Referring to FIGS. 1A and 1B, an electric lock 100 according to the embodiment is suitable for a compartment of a vehicle, such as a scooter, a motorcycle, powered by electricity or gasoline. The electric lock 100 includes a main base 110, a lock bolt 120, an elastic rod 130, a driving assembly 140, and a remote receiver 150.

The main base 110 is suitable to be fixed onto an inner wall surface of the compartment (not shown). The lock bolt 120 is pivotally rotatably disposed on a top surface TS of the main base 110 and is configured to lock a fastener on a seat (not shown).

The elastic rod 130 is movably arranged in a sleeve 111 of the main base 110 and connected to a free end FE of the lock bolt 120. Specifically, the sleeve 111 is disposed on a side of the main base 110 opposite to the lock bolt 120 and suspended above the top surface TS, and the elastic rod 130 penetrates through the sleeve 111 and is adapted to slide linearly along the sleeve 111 to drive the lock bolt 120.

The driving assembly 140 is disposed on a side of the main base 110 and is connected to the elastic rod 130. In addition, the driving assembly 140 is powered by an external power source to operate automatically. The remove receiver 150 is coupled to the driving assembly 140 and is adapted to receive a wireless signal (through a wireless transmission technology, such as infrared rays, Bluetooth, RFID, or the like). In a remote mode, the remote receiver 150 is adapted to receive a signal of a remote controller (not shown) to start the driving assembly 140, and the driving assembly 140 drives the lock bolt 120 through the elastic rod 130 to rotate relative to the main base 110, so as to switch to a locked state or an unlocked state.

Referring to FIGS. 1A and 1B a connection frame 160, a plurality of bolts 170, and a receptacle 180 are provided. The connection frame 160 is disposed on the main base 110, and the bolts 170 penetrate through a first end E1 of the connection frame 160 and the main base 110 to integrate the connection frame 160 and the main base 110. A second end E2 of the connection frame 160 forms an accommodating space AS to accommodate and be engaged with the driving assembly 140. The receptacle 180 is disposed on the connection frame 160 and coupled to the driving assembly 140, and is adapted to be coupled to the external power source to supply power to the driving assembly 140.

Referring to FIGS. 1A, 1B, and 2A, the driving assembly 140 includes a motor 141, a rotary plate 142, and a linking rod 143. The rotary plate 142 is disposed on a rotary shaft SF of the motor 141. The linking rod 143 is pivotally connected to an eccentric part of the rotary plate 142 and abuts against a portion of the elastic rod 130. The rotary shaft SF of the motor 141 is adapted to drive the rotary plate 142 to rotate along an axial direction AD, such as rotating in a clockwise direction or a counter-clockwise direction. Since the linking rod 143 is pivotally connected to the eccentric part of the rotary plate 142, the linking rod 143 may rotate eccentrically with the rotary plate 142 to move relatively close to the main base 110 and press the elastic rod 130 or move relatively away from the main base 110 and release the elastic rod 130.

Specifically, the linking rod 143 includes an eccentric block 1431, a pivot part 1432, and a gripping part 1433. The eccentric block 1431 is disposed on an outer periphery of the rotary plate 142. The pivot part 1432 is pivotally connected to the eccentric block 1431. The gripping part 1433 is screwed to an end of the pivot part 1432 away from the eccentric block 1431 and the gripping part 1433 has a recess G. A portion of the elastic rod 130 is located in the recess G.

In addition, the gripping part 1433 has a screw structure, and the pivot part 1432 has a screw hole. By combining the screwing structure and the screw hole, the length dimension of the gripping part 1433 and the pivot part 1432 is manually adjustable to meet the elastic strength of the elastic rod 130.

In the remote mode, the remote receiver 150 turns on the driving assembly 140. The rotary shaft SF of the motor 141 drives the rotary plate 142 to pivotally rotate in the clockwise or counter-clockwise direction.

During the rotation, as shown in FIG. 2A and then FIG. 2B, when the linking rod 143 is relatively close to the main base 110, the gripping part 1433 presses the elastic rod 130 to deform the elastic rod 130 and drive the lock bolt 120 to pivotally rotate relative to the main base 110 toward a first rotation direction T1, so as to switch to a locked state (i.e., a locking end GE of the lock bolt 120 protrudes outside the main base 110).

Referring to FIG. 2B and then FIG. 2A, when the linking rod 143 is relatively away from the main base 110, the gripping part 1433 stops pressing the elastic rod 130, and the elastic rod 130 is elastically restored and drives the lock bolt 120 to pivotally rotate relative to the main base 110 toward a second rotation direction T2 opposite to the first rotation direction T1, so as to switch to an unlocked state (i.e., the locking end GE of the lock bolt 120 overlaps with the top of the main base 110).

Referring to FIGS. 2A and 2C, in the manual mode, the remote receiver 150 and the driving assembly 140 are not activated. The user may pull the elastic rod 130 to slide linearly along the axial direction AD of the sleeve 111 toward a first direction D1 by an external force, so as to drive the lock bolt 120 to rotate relative to the main base 110 toward the first rotation direction T1 and switch to the locked state (i.e., the locking end GE of the lock bolt 120 protrudes out of the main base 110).

The user may also push the elastic rod 130 to slide along the axial direction AD of the sleeve 111 toward a second direction D2 opposite to the first direction D1 by an external force, so as to drive the lock bolt 120 to rotate toward the second rotation direction T2 relative to the main base 110 to switch to the unlocked state (i.e., the locking end GE of the lock bolt 120 overlaps with the top of the main base 110).

The elastic rod 130 is adapted to slide along the axial direction AD in the recess G of the gripping part 1433 without being interfered.

Referring to FIGS. 1A and 1B, the free end FE of the lock bolt 120 has a ring 121, and a first column B1 is pivotally arranged in the ring 121. The first end E1 of the elastic rod 130 is connected to the first column B1. When the elastic rod 130 drives the first column B1 along the axial direction AD, the free end FE of the lock bolt 120 is adapted to rotate relative to the first column B1 and be driven by the first column B1 to swing laterally relative to the main base 110 (as shown in FIGS. 2A and 2C).

The lock bolt 120 is provided with a through hole TH formed at the center of the lock bolt 120. The main base 110 has a second column B2 formed on the top surface TS. The through hole TH of the lock bolt 120 is sleeved on the second column B2 and is adapted to rotate about the second column B2 relative to the main base 110. Accordingly, the locking end GE of the lock bolt 120 protrudes out of the main base 110 or overlaps with the top surface TS of the main base 110.

In view of the foregoing, in the electric lock according to the embodiments of the invention, the remote controller transmits a wireless signal to the remote receiver to turn on the driving assembly. In addition, the driving assembly drives the lock bolt through the elastic rod to rotate relative to the main base, so as to switch to the locked state or the unlocked state. Accordingly, compared with a conventional lock that is locked or unlocked manually, the electric lock according to the embodiments of the invention is simple and convenient to operate.

Besides, the electric lock according to the embodiments of the invention can still be locked and unlocked manually. In the case where the remote controller is damaged, the electric lock can still be locked or unlocked manually, which further facilitate the convenience of the electric lock.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
