LOCKS AND WATERPROOF STRUCTURES THEREOF

TECHNICAL FIELD

The present disclosure generally relates to security systems, and more particularly, relates to locks and structures for resisting water and/or foreign objects.

BACKGROUND

A lock is an important tool to secure a device (e.g., a door, a bicycle, a drawer). The lock is generally exposed to natural circumstances. On the one hand, the lock is subjected to water erosion in outdoor use (e.g., a lock of a bicycle), which may damage the components (e.g., a communication module, a lock cylinder) that need to be isolated from water. On the other hand, the lock usually includes one or more openings to facilitate the locking and/or unlocking operations. Foreign matters (e.g., stones, tree branches) can fall in the openings, and the lock can get stuck, and the normal locking and/or unlocking operations can be affected. Therefore, it may be desirable to develop a lock with structures to protect the lock from being affected by an aqueous solution or other foreign matters. Besides, the lock can be shocked or hit by an external force in normal use or abnormal use. In this case, the lock can become loose, and the lock can be unexpectedly unlocked. Therefore, it may be desirable to develop a lock with structures to limit the position of a lock pin of the lock and prevent the lock from being unexpectedly unlocked.

In some embodiments, one or more components of the security system 100 may access the data and/or instructions stored in the storage 150 via the network 120. In some embodiments, the storage 150 may be directly connected to the server 110 as a backend storage. In some embodiments, one or more components of the security system 100 (e.g., the server 110, the terminal device 130, or the device 140) may have permissions to access the storage 150. In some embodiments, one or more components of the security system 100 may read and/or modify the information related to the user, and/or the device 140 when one or more conditions are met. For example, the server 110 may read and/or modify one or more users' information after a ride of a bicycle is completed.

In some embodiments, the device 140 may be a bicycle of a bicycle sharing system. The information exchange between one or more components of the security system 100 may be initiated by way of launching the mobile application of the bicycle sharing service on a terminal device 130, requesting a bicycle service, or inputting a query via the terminal device 130 (e.g., searching for a bicycle). The object of the service request may be any product. In some embodiments, the product may include food, medicine, commodity, chemical product, electrical appliance, clothing, car, housing, luxury, or the like, or any combination thereof. In some other embodiments, the product may include a service product, a financial product, a knowledge product, an internet product, or the like, or any combination thereof. The internet product may include an individual host product, a web product, a mobile internet product, a commercial host product, an embedded product, or the like, or any combination thereof. The mobile internet product may be used in a software of a mobile terminal, a program, a system, or the like, or any combination thereof. The mobile terminal may include a tablet computer, a laptop computer, a mobile phone, a personal digital assistant (PDA), a smartwatch, a point of sale (POS) device, an onboard computer, an onboard television, a wearable device, or the like, or any combination thereof. For example, the product may be any software and/or application used on the computer or mobile phone. The software and/or application may relate to socializing, shopping, transporting, entertainment, learning, investment, or the like, or any combination thereof. In some embodiments, the software and/or application related to transporting may include a traveling software and/or application, a vehicle scheduling software and/or application, a mapping software and/or application, etc.

One of ordinary skill in the art would understand that when an element of the security system 100 performs, the element may perform through electrical signals and/or electromagnetic signals. For example, when a terminal device 130 processes a task, such as making a determination, unlocking a device 140, the terminal device 130 may operate logic circuits in its processor to process such task. When the terminal device 130 transmits out a query (e.g., information relating to a location of a device 140) to the server 110, a processor of the terminal device 130 may generate electrical signals encoding the query. The processor of the terminal device 130 may then transmit the electrical signals to an output port. If the terminal device 130 communicates with the server 110 via a wired network, the output port may be physically connected to a cable, which further transmits the electrical signal to an input port of the server 110. If the terminal device 130 communicates with the server 110 via a wireless network, the output port of the terminal device 130 may be one or more antennas, which convert the electrical signals to electromagnetic signals. Similarly, a device 140 and/or a lock 170 may process a task through operation of logic circuits in its processor, and receive an instruction and/or service order from the server 110 via electrical signals or electromagnet signals. Within an electronic device, such as the terminal device 130, the device 140, the lock 170, and/or the server 110, when a processor thereof processes an instruction, transmits out an instruction, and/or performs an action, the instruction and/or action is conducted via electrical signals. For example, when the processor retrieves data (e.g., a plurality of user profiles) from a storage medium (e.g., the storage 150), it may transmit out electrical signals to a reading device of the storage medium, which may read structured data in the storage medium. The structured data may be transmitted to the processor in the form of electrical signals via a bus of the electronic device. Here, an electrical signal may refer to one electrical signal, a series of electrical signals, and/or a plurality of discrete electrical signals.

FIG. 2 a schematic diagram illustrating exemplary hardware and/or software components of a computing device 200 according to some embodiments of the present disclosure. The computing device 200 may be a general purpose computer or a special purpose computer. The computing device 200 may be used to implement any component of the security system 100 as described herein. For example, the processing engine 112 of the server 110, and/or the terminal device 130 may be implemented on the computing device 200, via its hardware, software program, firmware, or a combination thereof. Although only one such computer is shown for convenience, the computer functions related to the security system 100 as described herein may be implemented in a distributed manner on a number of similar platforms to distribute the processing load.

The computing device 200, for example, may include COM ports 250 connected to and from a network (e.g., the network 120) connected thereto to facilitate data communications. The computing device 200 may also include a processor 220 for executing program instructions to perform the functions of the server 110 described herein. The exemplary computer platform may include an internal communication bus 210, program storage and data storage of different forms, for example, a disk 270, and a read-only memory (ROM) 230, or a random access memory (RAM) 240, for various data files to be processed and/or transmitted by the computer. The exemplary computer platform may also include program instructions stored in the ROM 230, the RAM 240, and/or another type of non-transitory storage medium to be executed by the processor 220. The methods and/or processes of the present disclosure may be implemented as the program instructions. The computing device 200 also includes an I/O 260, supporting input/output between the computer, the user, and other components therein. The computing device 200 may also receive programming and data via network communications.

Merely for illustration, only one CPU and/or processor is described in the computing device 200. However, it should be noted that the computing device 200 in the present disclosure may also include multiple CPUs and/or processors, thus operation and/or method steps that are performed by one CPU and/or processor as described in the present disclosure may also be jointly or separately performed by the multiple CPUs and/or processors. For example, the CPU and/or processor of the computing device 200 may execute both step A and step B. As in another example, step A and step B may also be performed by two different CPUs and/or processors jointly or separately in the computing device 200 (e.g., the first processor executes step A and the second processor executes step B, or the first and second processors jointly execute steps A and B).

FIG. 3 is a schematic diagram illustrating exemplary hardware and/or software components of a mobile device 300 on which a terminal device may be implemented according to some embodiments of the present disclosure. As illustrated in FIG. 3, the mobile device 300 may include a communication module 310, a display 320, a graphics processing unit (GPU) 330, a processor 340, an I/O 350, a memory 360, and a storage 390. In some embodiments, any other suitable component, including but not limited to a system bus or a controller (not shown), may also be included in the mobile device 300. In some embodiments, a mobile operating system 370 (e.g., iOS™, Android™, Windows Phone™) and one or more applications 380 may be loaded into the memory 360 from the storage 390 in order to be executed by the processor 340. The applications 380 may include a browser or any other suitable apps for transmitting, receiving and presenting information relating to the status of the device 140 (e.g., the location of the device 140) from the server 110. User interactions with the information stream may be achieved via the I/O 350 and provided to the server 110 and/or other components of the security system 100 via the network 120. In some embodiments, a user may borrow (or rent) a device 140 (e.g., a bicycle) via the mobile device 300. The user may also control the lock 170 of the device 140 via the mobile device 300. For example, the user may input an instruction to close the lock via the mobile device 300.

FIG. 4 is a schematic diagram illustrating hardware components of an exemplary lock according to some embodiments of the present disclosure. The lock 170 may include one or more components including, for example, a lock tongue 401, a lock pin 402, a position limiting component 403, an execution component 404, a handle 405, a lock shell 420, a waterproof structure 430, a cover shield 440, and a processor 450. In some embodiments, one or more of the components may be omitted. For example, the waterproof structure 430, the cover shield 440, and/or the processor 450 may be omitted. More descriptions of the structure of the lock 170 may be found elsewhere in the present disclosure (e.g., FIGS. 5A-9C and the descriptions thereof).

The lock tongue 401 may be configured to secure an object (e.g., the device 140). The lock tongue 401 may be movable along a predetermined pathway. In some embodiments, an end of the lock tongue 401 may move between two positions (e.g., position C and position D as shown in FIG. 6A). The lock tongue 401 may be made of a material including, for example, stainless steel, copper, aluminum, iron, polystyrene (PS), polymethyl methacrylate (PMMA), polyformaldehyde (POM), polycarbonate (PC), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyphenylene oxide (PPO), or the like, or any combination thereof. In some embodiments, the lock tongue 401 may include one or more lock tongue grooves. The lock tongue grooves may coordinate with, e.g., the lock pin 402, to block the lock tongue 401 to move along an axial direction of the lock tongue 401 (between two positions, e.g., position C and position D as shown in FIG. 6A).

The lock pin 402 may be configured to block the lock tongue 401 to move along the axial direction of the lock tongue 401 under certain conditions. The lock pin 402 may be inserted into a lock tongue groove to block the lock tongue 401 to move along the axial direction of the lock tongue 401. In some embodiments, the lock pin 402 may include a coupling pin and a drive pin. The coupling pin may be connected to the drive pin. The drive pin may drive the coupling pin to be inserted into the lock tongue groove. In some embodiments, the lock pin 402 may be connected to an actuator motor. The actuator motor may drive the coupling pin to move. In some embodiments, the actuator motor may drive the lock pin to move away from the lock tongue groove to unlock the lock 170. In some embodiments, the lock pin 402 may be retractable along a reciprocating movement direction of the lock pin 402. For example, at least a portion of the lock pin 402 may be moveable inward or outward the lock shell 420. In some embodiments, the lock pin 402 or an inner side of the lock shell 420 may include one or more limit pinholes. The limit pinholes may coordinate with, e.g., the position limiting component 403, to block a position of the lock pin 402 to move along the axial direction of the lock pin 402. The reciprocating movement direction of the lock pin 402 may be equal to the axial direction of the lock pin 402.

The position limiting component 403 may be configured to block the lock pin 402 to move along the axial direction of the lock pin 402. In some embodiments, the position limiting component 403 may block the lock pin 402 to move along the axial direction of the lock pin 402 when the lock pin 402 blocks the lock tongue 401 to move along the axial direction of the lock tongue 401. For example, the position limiting component 403 may block the lock pin 402 to move away from the lock tongue groove. Therefore, the position of the lock pin 402 relative to the lock shell 420 may remain unchanged if there is no instruction for unlocking the lock 170. In some embodiments, the position limiting component 403 may include at least one fixing part and at least one telescopic part. In some embodiments, the at least one telescopic part may be connected to the at least one fixing part. In some embodiments, the fixing part may be fixed on the lock shell 420 or the lock pin 402. The telescopic part may be inserted into a limit pinhole of the lock pin 402 after the lock pin 402 blocks the lock tongue 401 to move along the axial direction of the lock tongue 401.

The execution component 404 may be configured to drive a first movement of the position limiting component 403 and/or a second movement of the lock pin 402. In some embodiments, the first movement of the position limiting component 403 may include a movement of the position limiting component 403 away from the limit pinhole. The second movement of the lock pin 402 may include a movement of the lock pin 402 away from the lock tongue groove. In some embodiments, the first movement of the position limiting component 403 may be earlier than the second movement of the lock pin 402.

In some embodiments, the execution component 404 may be accommodated in the lock shell 420. In some embodiments, the execution component 404 may be connected or attached to the lock pin 402 and/or the position limiting component 403. In some embodiments, the execution component 404 may include a drive mechanism and a transmission mechanism. The drive mechanism may include a stepper motor, a direct current (DC) motor, a servo motor, a synchronous motor, a switched reluctance motor, an asynchronous motor, etc. The transmission mechanism may include a rack transmission mechanism, a gear transmission mechanism, etc.

The handle 405 may be configured to facilitate a manual manipulation of the lock tongue 401. In some embodiments, the handle 405 may be installed on the lock tongue 401. The handle 405 may be movable along a predetermined pathway. In some embodiments, the handle 405 may move between two positions (e.g., position A and position B as shown in FIG. 6A). The lock tongue 401 may move along with the handle 405. The status of the lock 170 may change with the movement of the handle 405 and/or the lock tongue 401. For example, the lock 600 may have a locked status if the handle 603 is in the position B as illustrated in FIG. 6A. As another example, the lock 600 may have an unlocked status if the handle 603 is not in the position B (e.g., in the position A). As still another example, the lock 600 may have an unlocked status if a first end of the lock tongue 602 moves to a position C as illustrated in FIG. 6A. As still another example, the lock 600 may have a locked status as illustrated in FIG. 6A if the first end of the lock tongue 602 moves to a position D.

The lock shell 420 may be configured to accommodate at least a portion of the lock tongue 401, at least a portion of the lock pin 402, at least a portion of the position limiting component 403, at least a portion of the execution component 404, etc. For example, the lock shell 420 may accommodate the lock pin 402, the position limiting component 403, the execution component 404, at least a portion of the lock tongue 401, etc. In some embodiments, the lock shell 420 may be configured to accommodate other components of the lock 170 described elsewhere in the present disclosure (e.g., a positioning module, a communication module, a lock cylinder, or the like, or any combination thereof).

The waterproof structure 430 may be configured to protect at least a portion of the lock tongue 401, at least a portion of the lock pin 402, at least a portion of the position limiting component 403, at least a portion of the execution component 404, etc., from being exposed to water. In some embodiments, the waterproof structure 430 may include the lock shell 420, the lock pin 402, and a waterproof pipe. The waterproof pipe may be connected to the lock shell 420 and the lock pin 402, and the waterproof pipe may block the gap between the lock shell 420 and the lock pin 402. In some embodiments, the waterproof pipe may be arranged around at least a portion of the lock pin 402. In some embodiments, the waterproof pipe may be retractable. In some embodiments, the waterproof pipe may be retractable along the direction that is the same as or opposite to the movement direction of the lock pin 402. For example, if the at least a portion of the lock pin 402 moves outward the lock shell 420, the waterproof pipe may extend. As another example, if the at least a portion of the lock pin 402 moves inward the lock shell 420, the waterproof pipe may contract. In some embodiments, the waterproof pipe may be non-retractable. For example, the waterproof pipe may be flexible and long enough to be arranged around at least a portion of the lock pin 402 that is moveable inward or outward the lock shell 420. In some embodiments, the waterproof structure 430 described herein may be used in other types of devices, e.g., a keyboard, a camera, a recorder.

The cover shield 440 may be configured to close an opening of the lock shell 420, and prevent an object from falling into the lock shell 420 through the opening. For example, the cover shield 440 may prevent objects like stones and tree branches from falling inside the lock shell 420. In some embodiments, the cover shield 440 may close the opening when the lock 170 is locked. Alternatively or additionally, the cover shield 440 may close the opening when the lock 170 is unlocked. In some embodiments, the cover shield 440 may be connected to the handle 405, the lock shell 420, the lock tongue 401, or a combination thereof.

The processor 450 may be configured to control one or more components of the lock 170 (e.g., the lock tongue 401, the lock pin 402, the position limiting component 403, the execution component 404, the handle 405). For example, the processor 450 may be configured to transmit one or more instructions to the execution component 404 to drive the first movement of the position limiting component 403 and/or the second movement of the lock pin 402 to unlock the lock 170. The instruction may include a user's input by, for example, pressing a button, pressing a digit button, inputting a correct password, scanning a barcode for unlocking the lock 170, etc. In some embodiments, the processor 450 may be accommodated in the lock shell 420.

It should be noted that the above description of the lock 170 is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, one or more components of the lock 170 (e.g., the waterproof structure 430, the cover shield 440, the position limiting component 403, the processor 450) may be omitted.

FIGS. 5A-5D illustrate sectional views of two exemplary waterproof structures according to some embodiments of the present disclosure. As shown in FIG. 5A, the waterproof structure 500a may include a sealing wall 510, a reciprocating piece 501, a sealing ring 502, and a waterproof space 503.

In some embodiments, the sealing ring 502 may be accommodated between the sealing wall 510 and the reciprocating piece 501. The sealing ring 502 may fill a gap between the sealing wall 510 and the reciprocating piece 501, and seal the sealing wall 510. In some embodiments, the sealing ring 502 may be mechanically connected to the sealing wall 510 and the reciprocating piece 501. A cross section shape of the sealing ring 502 may vary. For example, the cross section shape of the sealing ring 502 may be U-shaped, O-shaped, rectangular, or Y-shaped. The material of the sealing ring 502 may vary. For example, the sealing ring 502 may be made of a material including, for example, acrylonitrile-butadiene rubber (NBR), hydrogenated butadiene-acrylonitrile rubber (HNBR), silicone rubber, fluororubber, ethylene propylene rubber (EPR), chloroprene rubber, butyl rubber, natural rubber, polyurethane rubber, metallic rubber, or the like, or any combination thereof.

The waterproof space 503 may refer to an isolated place into which water may be prevented from flowing. In some embodiments, the sealing wall 510 and the reciprocating piece 501 may be sealed by the sealing ring 502. Therefore, the sealing wall 510, the reciprocating piece 501, and the sealing ring 502 may enclose the waterproof space 503. In some embodiments, water may be prevented from flowing into the waterproof space 503 when at least a portion of the reciprocating piece 501 moves inward or outward the sealing wall 510 along the directions as indicated by the arrows in FIG. 5A. In some embodiments, the reciprocating piece 501 may apply a force on the sealing ring 502 during the movement of the reciprocating piece 501.

As shown in FIGS. 5B-5D, the waterproof structure 500b may include the sealing wall 510, the reciprocating piece 501, the waterproof space 503, a waterproof pipe 520, and a through-hole 504. In some embodiments, the at least a portion of the reciprocating piece 501 may be moveable inward or outward the sealing wall 510 through the through-hole 504 along the direction as indicated by the arrows in FIG. 5B. In some embodiments, the waterproof pipe 520 may be connected to the sealing wall 510 and the reciprocating piece 501, and the waterproof pipe 520 may block the gap between the sealing wall 510 and the reciprocating piece 501. Therefore, the sealing wall 510, the reciprocating piece 501, and the waterproof pipe 520 may enclose the waterproof space 503.

In some embodiments, the waterproof pipe 520 may be arranged around the at least a portion of the reciprocating piece 501. In some embodiments, the waterproof pipe 520 may be retractable. In some embodiments, the waterproof pipe 520 may be retractable along the direction that is the same as or opposite to the movement direction of the at least a portion of the reciprocating piece 501 (e.g., along the direction as indicated by the arrows in FIG. 5B). In some embodiments, if the at least a portion of the reciprocating piece 501 moves outward the sealing wall 510, the waterproof pipe 520 may extend, and the length of the waterproof pipe 520 may increase; if the at least a portion of the reciprocating piece 501 moves inward the sealing wall 510, the waterproof pipe 520 may contract, and the length of the waterproof pipe 520 may decrease. In some embodiments, if the at least a portion of the reciprocating piece 501 moves inward the sealing wall 510, the waterproof pipe 520 may extend, and the length of the waterproof pipe 520 may increase; if the at least a portion of the reciprocating piece 501 moves outward the sealing wall 510, the waterproof pipe 520 may contract, and the length of the waterproof pipe 520 may decrease. Since the waterproof pipe 520 may extend or contract along with the movement of the at least a portion of the reciprocating piece 501, the at least a portion of the reciprocating piece 501 may move without resistance from the waterproof pipe 520. Therefore, the service life of the waterproof pipe 520 may be lengthened, and water may be prevented from flowing into the waterproof space 503 even after the reciprocating piece 501 has moved for many times. It should be noted that in some embodiments, the waterproof pipe 520 may be non-retractable. For example, the waterproof pipe 520 may be flexible and long enough to be arranged around at least a portion of the reciprocating piece 501 that is moveable inward or outward the sealing wall 510.

In some embodiments, the waterproof pipe 520 may be made of a material including at least one of a flexible material, an anticorrosion material, an elastic material, a wear-resistant material, or the like, or any combination thereof. Exemplary anticorrosion materials may include stainless steel, titanium, titanium alloy, phenolic resin, epoxy resin, NBR, HNBR, silicone rubber, fluororubber, EPR, chloroprene rubber, butyl rubber, natural rubber, polyurethane rubber, metallic rubber, or the like, or any combination thereof. Exemplary elastic materials may include NBR, HNBR, silicone rubber, fluororubber, EPR, chloroprene rubber, butyl rubber, natural rubber, metallic rubber, polyurethane elastomer, polyolefin elastomer, styrene-butadiene-styrene (SBS), or the like, or any combination thereof. Exemplary wear-resistant materials may include NBR, HNBR, silicone rubber, fluororubber, EPR, chloroprene rubber, butyl rubber, natural rubber, metallic rubber, polyurethane elastomer, polyolefin elastomer, SBS, polytetrafluoroethylene (PTEF), or the like, or any combination thereof.

In some embodiments, the waterproof pipe 520 may include a first connection end 5201 and a second connection end 5202. In some embodiments, the first connection end 5201 of the waterproof pipe 520 may connect to the sealing wall 510. In some embodiments, the second connection end 5202 of the waterproof pipe 520 may connect to the reciprocating piece 501. In some embodiments, the connection between the first connection end 5201 of the waterproof pipe 520 and the sealing wall 510, and/or the connection between the second connection end 5202 of the waterproof pipe 520 and the reciprocating piece 501 may be realized using glue. In some embodiments, a first aperture size of the first connection end 5201 of the waterproof pipe 520 may be larger than a second aperture size of the second connection end 5202 of the waterproof pipe 520. In some embodiments, at least a portion of the waterproof pipe 520 between the first connection end 5201 and the second connection end 5202 may be a corrugated telescopic pipe, or a spiral telescopic pipe, or the like. Water flowing into the through-hole 504 may be blocked by the first connection end 5201 and the second connection end 5202 of the waterproof pipe 520, and may not flow into the waterproof space 503.

In some embodiments, the first connection end 5201 of the waterproof pipe 520 may connect to the sealing wall 510 in various ways. For example, as shown in FIG. 5B, the first connection end 5201 of the waterproof pipe 520 may connect to an inner side of the sealing wall 510. As another example, as shown in FIG. 5C, the first connection end 5201 of the waterproof pipe 520 may connect to a wall of the through-hole 504. In some embodiments, at least a portion of the first connection end 5201 may not be directly in contact with the reciprocating piece 501. Accordingly, there may be a gap between the first connection end 5201 of the waterproof pipe 520 and the reciprocating piece 501. In some embodiments, the width of the gap between the first connection end 5201 and the reciprocating piece 501 may be less than a predetermined or suitable value (e.g., 1 mm, 2 mm, 3 mm, etc.). In some embodiments, the second connection end 5202 may be directly in contact with the reciprocating piece 501.

In some embodiments, the first connection end 5201 and/or the second connection end 5202 of the waterproof pipe 520 may include one or more protruding elements. Accordingly, the sealing wall 510 and/or the reciprocating piece 501 may include one or more grooves corresponding to the protruding element(s). The connection between the first connection end 5201 of the waterproof pipe 520 and the sealing wall 510, and/or the connection between the second connection end 5202 of the waterproof pipe 520 and the reciprocating piece 501 may be enhanced because of the protruding element(s) and the groove(s). Therefore, a separation of the first connection end 5201 from the sealing wall 510 and a separation of the second connection end 5202 from the reciprocating piece 501 may be avoided even after the reciprocating piece 501 has moved for many times.

Merely by way of example, the first connection end 5201 of the waterproof pipe 520 may include a first protruding element (not shown). If the first connection end 5201 connects to the inner side of the sealing wall 510, the inner side of the sealing wall 510 may include a first groove (not shown) corresponding to the first protruding element. If the first connection end 5201 connects to the wall of the through-hole 504, the wall of the through-hole 504 may include a first groove (not shown) corresponding to the first protruding element. In some embodiments, the lock shell (e.g., the lock shell 420 (see FIG. 4), the lock shell 601 (see FIGS. 6A-6D)) may be used as the sealing wall 510. Accordingly, the inner side of the lock shell or the wall of the through-hole of the lock shell may include a first groove corresponding to the first protruding element. In some embodiments, the first protruding element may be insertable in the first groove, and the connection between the first connection end 5201 of the waterproof pipe 520 and the sealing wall 510 or the through-hole 504 may be enhanced.

As another example, as shown in FIG. 5D, the second connection end 5202 of the waterproof pipe 520 may include a second protruding element 5203. In some embodiments, the reciprocating piece 501 may include a second groove 5014 corresponding to the second protruding element 5203. In some embodiments, the lock pin (e.g., the lock pin 402 (see FIG. 4), the lock pin 720 (see FIGS. 8A-9C)) may be used as the reciprocating piece 501. Accordingly, the lock pin may include a second groove. The second protruding element 5203 may be insertable in the second groove 5014, and the connection between the second connection end 5202 of the waterproof pipe 520 and the reciprocating piece 501 may be enhanced.

In some embodiments, a cross section shape of the protruding element(s) may vary. For example, the cross section shape of the protruding element(s) may be annular, toroidal, cylindrical, cubic, tri-prism, etc. Accordingly, the groove(s) may have the cross section shape(s) corresponding to the protruding element(s). For example, if a cross section shape of a protruding element is cylindrical, a corresponding cross section shape of a groove may be cylindrical. As another example, if a cross section shape of a protruding element is tri-prism, a cross section shape of a corresponding groove may be tri-prism.

The waterproof structure 500b may be applied in various devices including, for example, a lock of the device 140, a keyboard, a button of a camera, a button of a recorder, or the like.

As shown in FIG. 9B, the telescopic part 7302 may be inserted into the limit pinhole 7201 of the lock shell 710 once the lock pin 720 blocks the lock tongue 703 to move along an axial direction of the lock tongue 703. As shown in FIG. 9C, after receiving an instruction for unlocking the lock 950, the execution component 740 may drive the position limiting component 730 to move away from the lock shell 710. In some embodiments, the execution component 740 may then drive the lock pin 720 to move away from the lock tongue 703 to unlock the lock 950. Exemplary instructions may include an input of a user of the device 140 by, for example, pressing a button, pressing a digit button, inputting a password, scanning a barcode for unlocking the lock, etc.

In some embodiments, the lock 800 (or the lock 900, or the lock 950) may include a processor (not shown). The processor may transmit one or more instructions to the execution component 740 to drive the first movement of the position limiting component 730 and/or the second movement of the lock pin 720 to unlock the lock 800 (or the lock 900, or the lock 950). The instruction may include the user's input by, for example, pressing a button, pressing a digit button, inputting a correct password, scanning a barcode for unlocking the lock, etc. In some embodiments, at least a portion of the execution component 740 may be electrically connected to the processor. The processor may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction-set processor (ASIP), a graphics processing unit (GPU), a physics processing unit (PPU), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction-set computer (RISC), a microprocessor, or the like, or any combination thereof.

This description is intended to be illustrative, and not to limit the scope of the present disclosure. Many alternatives, modifications, and variations will be apparent to those skilled in the art. The features, structures, methods, and other characteristics of the exemplary embodiments described herein may be combined in various ways to obtain additional and/or alternative exemplary embodiments. However, those variations and modifications do not depart the scope of the present disclosure.

It should be noted that the above description of the lock 800, the lock 900, and the lock 950 is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, the lock 800, the lock 900, or the lock 950 may further include a waterproof structure as illustrated in FIGS. 5A-5D. As another example, the lock 800, the lock 900, or the lock 950 may further include a cover shield as illustrated in FIGS. 6A-6F.

FIG. 10 is a flowchart illustrating an exemplary process for unlocking a lock according to some embodiments of the present disclosure. In some embodiments, the process 1000 for unlocking a lock (e.g., the lock illustrated in FIGS. 6A-9C) may be implemented in the security system 100 as illustrated in FIG. 1. One or more operations of the process 1000 may be implemented in a terminal device 130 and/or the server 110. One or more operations of the process 1000 may also be implemented as one or more instructions stored in the storage 150 and called and/or executed by the processing engine 112. The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 1000 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 1000 as illustrated in FIG. 10 and described below is not intended to be limiting.

In 1010, a remote processor (e.g., the processing engine 112, the processor 220, the processor 340, etc.) may send one or more instructions to an execution component (e.g., the execution component 740 as shown in FIGS. 9A and 8A). The instruction may instruct the execution component 740 to unlock a lock described in FIGS. 8A-9C. In some embodiments, a user of the device 140 may send the instruction to the remote processor. The remote processor may then send the instruction to the execution component 740. In some embodiments, the user of the device 140 may send the instruction to a processor (e.g., the processor 450) of a lock (e.g., the lock 800, the lock 900, the lock 950). The processor of the lock may then send the instruction to the execution component 740. The instruction may include the user's input by, for example, pressing a button, pressing a digit button, inputting a password, scanning a barcode for unlocking the lock, etc.

In 1020, the execution component 740 may drive a position limiting component (e.g., the position limiting component 730 as shown in FIGS. 8A-9C) to release a position limitation of a lock pin (e.g., the lock pin 720 as shown in FIGS. 8A-9C). In some embodiments, a drive mechanism of the execution component 740 may output a force. A transmission mechanism of the execution component 740 may transmit the force to drive the position limiting component to release a position limitation of the lock pin. For example, as illustrated in FIGS. 8A-9C, a first portion of the transmission mechanism may transmit the force to drive a telescopic part 7302 of the position limiting component 730 to move away from the limit pinhole 7201 arranged on the coupling pin 702 or the lock shell 710.

In 1030, the execution component 740 may drive the lock pin (e.g., the lock pin 720) to move away from the lock tongue 703 to unlock a lock (e.g., the lock 800, the lock 900, the lock 950). In some embodiments, the execution component 740 may drive the lock pin to move after the position limitation of the lock pin is released. In some embodiments, the transmission mechanism of the execution component 740 may transmit the force to drive a coupling pin (e.g., the coupling pin 702) of the lock pin (e.g., the lock pin 720) to move away from the lock tongue groove. For example, as illustrated in FIGS. 8A-9C, a second portion of the transmission mechanism may transmit the force to drive the coupling pin 702 to move away from the lock tongue groove.

It should be noted that the above description of the process 1000 is merely provided for illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, the operations 1020 and 1030 may be performed simultaneously, and the operations 1020 and 1030 may be integrated into one single operation.

Having thus described the basic concepts, it may be rather apparent to those skilled in the art after reading this detailed disclosure that the foregoing detailed disclosure is intended to be presented by way of example only and is not limiting. Various alterations, improvements, and modifications may occur and are intended to those skilled in the art, though not expressly stated herein. These alterations, improvements, and modifications are intended to be suggested by this disclosure and are within the spirit and scope of the exemplary embodiments of this disclosure.

Moreover, certain terminology has been used to describe embodiments of the present disclosure. For example, the terms “one embodiment,” “an embodiment,” and/or “some embodiments” mean that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Therefore, it is emphasized and should be appreciated that two or more references to “an embodiment” or “one embodiment” or “an alternative embodiment” in various portions of this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined as suitable in one or more embodiments of the present disclosure.

Further, it will be appreciated by one skilled in the art, aspects of the present disclosure may be illustrated and described herein in any of a number of patentable classes or context including any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof. Accordingly, aspects of the present disclosure may be implemented entirely hardware, entirely software (including firmware, resident software, micro-code, etc.) or combining software and hardware implementation that may all generally be referred to herein as a “unit,” “module,” or “system.” Furthermore, aspects of the present disclosure may take the form of a computer program product embodied in one or more computer-readable media having computer readable program code embodied thereon.

A computer readable signal medium may include a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated signal may take any of a variety of forms, including electromagnetic, optical, or the like, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that may communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable signal medium may be transmitted using any appropriate medium, including wireless, wireline, optical fiber cable, RF, or the like, or any suitable combination of the foregoing.

Computer program code for carrying out operations for aspects of the present disclosure may be written in any combination of one or more programming languages, including an object-oriented programming language such as Java, Scala, Smalltalk, Eiffel, JADE, Emerald, C++, C#, VB. NET, Python or the like, conventional procedural programming languages, such as the “C” programming language, Visual Basic, Fortran 2103, Perl, COBOL 2102, PHP, ABAP, dynamic programming languages such as Python, Ruby, and Groovy, or other programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider) or in a cloud computing environment or offered as a service such as a Software as a Service (SaaS).

Furthermore, the recited order of processing elements or sequences, or the use of numbers, letters, or other designations, therefore, is not intended to limit the claimed processes and methods to any order except as may be specified in the claims. Although the above disclosure discusses through various examples what is currently considered to be a variety of useful embodiments of the disclosure, it is to be understood that such detail is solely for that purpose and that the appended claims are not limited to the disclosed embodiments, but, on the contrary, are intended to cover modifications and equivalent arrangements that are within the spirit and scope of the disclosed embodiments. For example, although the implementation of various components described above may be embodied in a hardware device, it may also be implemented as a software-only solution, for example, an installation on an existing server or mobile device.
