FIG. 5 illustrates a system structure drawing of the smart doorbell in the first embodiment of the present invention.

In the first embodiment of the present invention, as shown in FIG. 1, FIG. 2 and FIG. 5, the smart doorbell 1 has the anti-theft function, and the smart doorbell 1 can generate an alert when a person maliciously disassembles the smart doorbell 1. The smart doorbell 1 includes a case set 10, a lens 20, a circuit board 30, a vibration sensing module 40, a locking unit 50, a vibration unit 60, a vibration transferring unit 70 and an alarm module 80.

In the first embodiment of the present invention, the case set 10 includes a first case 11, a second case 12 and a hole 13. The first case 11 is the case towards outside, and the second case 12 is the case which is attached to the wall (wherein the second case 12 is shown with dotted lines in FIG. 2). The first case 11 is combined with the second case 12. The hole 13 is located in the first case 11.

In the first embodiment of the present invention, the lens 20 is disposed on the circuit board 30, and the lens 20 is electrically connected to the vibration sensing module 40 and the alarm module 80. The lens 20 is exposed to the outside of the case set 10 through the hole 13 to capture an image of the outside of the case set 10. The circuit board 30 is located inside the case set 10. The vibration sensing module 40 is connected to the circuit board 30. The vibration sensing module 40 can receive the image captured by the lens 20 and determine if there is a vibration by checking if the image captured by the lens 20 shakes.

The locking unit 50 locks the first case 11 and the second case 12. If there is a need to disassemble the case set 10, the locking unit 50 must be rotated to release the locking between the locking unit 50, the first case 11 and the second case 12. In the first embodiment of the present invention, the locking unit 50 is a screw. If there is a need to open the case set 10, a user may use a screwdriver to rotate the screw of the locking unit 50 to release the locking among the locking unit 50, the first case 11 and the second case 12.

In the first embodiment of the present invention, as shown in FIG. 2 to FIG. 4, the vibration unit 60 is connected to the top of the locking unit 50. The vibration unit 60 includes a plurality of crests 61 and a plurality of troughs 62. The crests 61 and the troughs 62 are aligned alternatingly along a circumference direction of the locking unit 50, and in a shape as a gear. When the locking unit 50 rotates, the locking unit 50 will cause the vibration unit 60 to rotate.

In the first embodiment of the present invention, the vibration transferring unit 70 contacts the vibration unit 60. The vibration transferring unit 70 includes a moving unit 71, an elastic unit 72 and a containing tube 73. The moving unit 71 is a sphere, and the vibration transferring unit 70 contacts the vibration unit 60 via the moving unit 71. The elastic unit 72 is a spring. The elastic unit 72 is connected to the moving unit 71 and located in the containing tube 73. The elastic force of the elastic unit 72 can push the moving unit 71 such that the moving unit 71 moves along the moving direction B shown in FIG. 4. One end of the containing tube 73 of the vibration transferring unit 70 is connected to the circuit board 30, and the moving unit 71 is located at the other end of the containing tube 73.

In the first embodiment of the present invention, as shown in FIG. 2 and FIG. 5, the alarm module 80 is disposed on the circuit board 30 and electrically connected to the vibration sensing module 40. The alarm module 80, as a specific example, is a network module connected to a police station or security agency server. When the vibration sensing module 40 senses a vibration, the vibration sensing module 40 will send a signal to the alarm module 80, and the alarm module 80 will then notify the police station or security agency.

In the first embodiment of the present invention, as shown in FIG. 2, if a thief wants to disassemble the case set 10 to damage the electronic components in the case set 10, the thief may use a screwdriver to rotate the locking unit 50 along the rotation direction R shown in FIG. 2. When the locking unit 50 rotates along the rotation direction R, the locking unit 50 will cause the vibration unit 60 to rotate along the rotation direction R along with the locking unit 50; as shown in FIG. 3, as the vibration unit 60 rotates along the rotation direction R, if one of the crests 61 displaces the moving unit 71, the moving unit 71 will move along the moving direction A shown in FIG. 3 and the elastic unit 72 will be compressed and deformed to provide an elastic force to push the moving unit 71; then, as shown in FIG. 4, since the moving unit 71 is pushed by the elastic unit 72, if the vibration unit 60 keeps rotating along the rotation direction R such that the crest 61 shifts, the moving unit 71, which is pushed, will move along the moving direction B and fall onto the trough 62 next to the shifting crest 61; then, if the vibration unit 60 keeps rotating along the rotation direction R, another adjacent crest 61 will displace the moving unit 71 such that the moving unit 71 moves along the moving direction A (which means that the vibration transferring unit 70 returns to the state shown in FIG. 3); thus, during the process of the vibration unit 60 rotating along the rotation direction R, the moving unit 71 moves back and forth on the crests 61 and the troughs 62 to generate a vibration. More particularly, during the process of the vibration unit 60 rotating along the rotation direction R, the moving unit 71 moves back and forth along the moving direction A and the moving direction B to generate the vibration.

The vibration generated by the back-and-forth movement of the moving unit 71 is transferred to the circuit board 30 via the elastic unit 72 and the containing tube 73 to cause the lens 20 on the circuit board 30 to shake regularly. Therefore, the shaking lens 20 will capture a shaking image, and the vibration sensing module 40 receives the shaking image captured by the lens 20. The vibration sensing module 40 can sense the vibration by receiving the shaking image. When the vibration sensing module 40 determines that there is a vibration, the vibration sensing module 40 will send a signal to the alarm module 80, and the alarm module 80 will then notify the police station or security agency. By this design, the police station or security agency will be alerted that someone is disassembling the case set 10 and the police station or security agency can execute a corresponding security action to achieve the anti-theft function.

It is to be known that, although wind or rain can also cause the lens 20 or the circuit board 30 to shake slightly in random directions, during the process of the vibration unit 60 of the present invention rotating along the rotation direction R, the back-and-forth movement of the moving unit 71 on the plurality of crests 61 and the plurality of troughs 62 will generate a regular vibration, not a random vibration; thus, the vibration sensing module 40 of the present invention can be further designed to determine that the vibration is generated when the shaking image captured by the lens 20 shakes regularly, and to send the signal to the alarm module 80, to prevent the random shaking caused by wind or rain from being mistaken as shaking caused by a thief disassembling the case set 10 and thus to prevent accidental triggering of the anti-theft function.

Furthermore, since wind or rain may only cause the circuit board 30 or the lens 20 to shake slightly (in the practical experiments performed by the applicant of this invention, the common wind and rain caused the circuit board 30 generate shaking with an amplitude of 0.1 mm) in random directions, the vibration sensing module 40 of the present invention can be further designed such that the following conditions apply: If the shaking amplitude of the image captured by the lens 20 is more than 1 mm, and the shaking direction of the image captured by the lens 20 is in the moving directions A, B, the vibration sensing module 40 will determine that there is a vibration and send the signal to the alarm module 80, to prevent the random shaking caused by wind or rain from being mistaken as shaking caused by a thief disassembling the case set 10 and thus to prevent accidental triggering of the anti-theft function. However, the shaking amplitude threshold of the image is not limited to 1 mm; it can be changed according to design requirements.

Furthermore, if a maintenance worker of the smart doorbell 1 needs to open the case set 10 to repair the electronic components, the smart doorbell 1 can also be designed to provide a safe removal mechanism such that the maintenance worker can disassemble the case set 10 without triggering the anti-theft function. For example, the alarm module 80 can provide a temporary shutdown mode; if the maintenance worker accesses the smart doorbell 1 via the network and inputs a specific password, the alarm module 80 will execute the temporary shut-down mode to shut down for a specific time. By this design, the maintenance worker can disassemble the case set 10 within that specific time without triggering the anti-theft function.

Please refer to FIG. 6, which illustrates the smart doorbell in the second embodiment of the present invention. FIG. 6 illustrates a schematic drawing of the vibration unit contacting the vibration transferring unit in the second embodiment of the present invention.

As shown in FIG. 6, the difference between the second embodiment and the first embodiment is that, in the second embodiment, the vibration unit 60a includes the plurality of crests 61a and the plurality of troughs 62a. The crests 61a and the troughs 62a of the vibration unit 60a are aligned alternatingly and in a shape as a radial disc, and the radial disc is located on the bottom of the locking unit 50a. When the locking unit 50a rotates, the moving unit 71 will move back and forth on the plurality of crests 61a and the plurality of troughs 62a on the radial disc to generate a vibration. Please refer to FIG. 7, which illustrates the smart doorbell in the third embodiment of the present invention. FIG. 7 illustrates a schematic drawing of the vibration unit contacting the vibration transferring unit in the third embodiment of the present invention.

As shown in FIG. 7, the difference between the third embodiment and the first embodiment is described below. When the case set is being disassembled, the locking unit 50b rotates along the counterclockwise rotation direction Rlshow in FIG. 7. The vibration unit 60b is connected to the top of the locking unit 50b and includes the plurality of crests 61b and the plurality of troughs 62b. The crests 61b and the troughs 62b of the vibration unit 60b are aligned alternatingly and in a shape as a radical star-shaped structure. The vibration transferring unit 70a includes a moving unit 71a and an elastic unit 72, but the vibration transferring unit 70a does not include the containing tube; the moving unit 71a is a sheet, one end of the moving unit 71a is pivotally connected to the case set 10, and the other end of the moving unit 71a contacts the vibration unit 60b. The elastic unit 72a is still a spring. One end of the elastic unit 72 is connected to the moving unit 71a, and the other end of the elastic unit 72 is connected to the vibration sensing module 40a. In the third embodiment, the vibration sensing module 40a is a piezoelectric sensor.

When the locking unit 50b rotates along the rotation direction R1, the locking unit 50b will cause the vibration unit 60b to rotate; one of the crests 61b which contacts the moving unit 71a will move the moving unit 71a; when the vibration unit 60b keeps rotating such that the crest 61b leaves the moving unit 71a, the elastic force of the elastic unit 72 will pull the sheet of the moving unit 71a such that the sheet of the moving unit 71a crosses the adjacent trough 62b and contacts the adjacent crest 61b. By this design, the moving unit 71a can move back and forth on the plurality of crests 61b and the plurality of troughs 62b; more particularly, during the process of the vibration unit 60b rotating along the rotation direction R1, the moving unit 71a will swing back and forth, and the moving unit 71a will pull the elastic unit 72 to generate a vibration. The elastic unit 72 will transfer the vibration to the piezoelectric sensor of the vibration sensing module 40a such that the vibration sensing module 40 senses the vibration and sends the signal to the alarm module 80.

By the design of the smart doorbell 1 of the present invention, the smart doorbell 1 has an anti-theft function. When people maliciously disassemble the case set of the smart doorbell 1, the vibration unit and the vibration transferring unit will be triggered to generate the vibration. By this design, the vibration sensing module will sense the vibration and alert a police station or security service.
