Technical Field
[0001] This utility model relates to the field of two-wheeled motor vehicle technology, and in particular to an electronically controlled lock with mechanical unlocking. Background Technology
[0002] Existing two-wheeled motor vehicle steering locks use electronic unlocking, which does not require a key. After successful sensing, pressing the start button will unlock the lock. However, the electronic control system has potential risks such as battery depletion and circuit failure. Therefore, mechanical unlocking is essential. We propose to design an electronic lock that can be unlocked both mechanically and electronically without affecting each other. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present utility model aims to provide an electronically controlled lock with mechanical unlocking, wherein the drive plate drives the driven block through the first elastic element, and the clutch push plate abuts against the driven part to drive the driven block, without affecting each other.
[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This type of electrically controlled lock with mechanical unlocking includes a housing, within which a lock cylinder, a motor, a driven block, a drive plate, and a clutch push plate are provided. The lock cylinder is rotatably arranged with its rotation center line extending vertically. The lock cylinder is connected to a swing block. The motor is driven by a drive wheel, which is rotatably arranged with its rotation center line extending vertically. The drive wheel has an eccentric shaft. The driven block has a latch on its front side and a driven part. The drive plate has a first transmission hole and is movable back and forth. A first elastic element is provided between the drive plate and the driven block. The clutch push plate has a second transmission hole and is movable back and forth. The clutch push plate abuts against the front side of the driven part. The first transmission hole and the second transmission hole respectively cooperate with the swing block and the eccentric shaft.
[0005] In this scheme, the first transmission hole and the second transmission hole convert the swing of the swing block and the eccentric shaft into the forward and backward movement of the drive plate and the clutch push plate. When unlocking, the drive plate drives the driven block to move backward through the first elastic element, and the driven part separates from the clutch push plate, or the clutch push plate abuts against the front side of the driven part and drives the driven block to move backward, and the first elastic element deforms to adapt.
[0006] Preferably, the driven block and the driving plate together form a mounting cavity, and the first elastic element is provided in the mounting cavity along the front-to-back direction. The front cavity wall and the rear cavity wall of the mounting cavity are both composed of the driven block and the driving plate.
[0007] In this scheme, the first elastic element is in a compressed state in the mounting cavity. Compared with the free state, the structure is compact and the elastic force generated by the unit deformation is large. When the driven block and the driving plate undergo relative displacement in the front-to-back direction, the first elastic element will be further compressed and generate elastic force on the driven block and the driving plate.
[0008] Preferably, the driven block is provided with grooves arranged opposite each other in the vertical direction, the drive plate is provided with a first through hole, the groove wall and the hole wall of the first through hole together form the front cavity wall and the rear cavity wall of the mounting cavity, and the front hole wall and the rear hole wall of the first through hole are provided with mounting posts for the first elastic element to be sleeved.
[0009] In this design, when the first elastic element is compressed, one end abuts against the groove wall of the upper and lower grooves, and the middle of the other end abuts against the wall of the first through hole, so the force is even and it will not bend.
[0010] Preferably, the motor is positioned below the driven block in a left-right direction. The motor is connected to a worm gear, which meshes with a helical gear. An intermediate gear is coaxially arranged with the helical gear, and the intermediate gear meshes with a driven gear. The driven gear is coaxially arranged with the drive wheel, and the drive wheel is located behind the driven block.
[0011] In this design, the motor is positioned below the driven block in the left-right direction, and the drive wheel is positioned behind the driven block, so the housing is not too wide in the left-right direction.
[0012] Preferably, the eccentric shaft extends into the first transmission hole, and the first transmission hole extends in the left-right direction.
[0013] In this scheme, the rotation of the eccentric shaft around the rotation center line is decomposed into the left and right displacement of the eccentric shaft within the first transmission hole and the front and back displacement of the eccentric shaft and the drive plate.
[0014] Preferably, the clutch push plate is further provided with a clutch hole, into which the driven part extends and moves back and forth relative to the clutch push plate, and the wall of the clutch hole cooperates with the front side of the driven part.
[0015] In this scheme, the clutch hole wall separates from the front side of the driven part during electronic unlocking, and the clutch hole wall abuts against the front side of the driven part during mechanical unlocking.
[0016] Preferably, the second transmission hole allows the swing block to extend into and swing, the wall of the second transmission hole cooperates with the rear side of the swing block, the lock cylinder has a key insertion hole, and the lock cylinder is located behind the driven part.
[0017] In this scheme, the key is inserted into the lock cylinder to drive the lock cylinder to rotate, the swing block swings to drive the clutch push plate to move backward, the first elastic element deforms, the clutch push plate moves forward, and the driven block will reset due to the elastic force of the first elastic element.
[0018] Preferably, the lock cylinder is connected to a locking part, the locking part abuts against the rear side of the locking block, and a second elastic element is provided between the locking block and the housing.
[0019] In this design, the locking part abuts against the locking block to prevent the lock cylinder from rotating due to the elastic force of the first elastic element, thus maintaining the unlocking effect.
[0020] Preferably, a third elastic element is provided between the housing and the driven block, and the third elastic element is sleeved on the locking tongue.
[0021] In this design, the second elastic element keeps the locking tongue extended.
[0022] Preferably, the clutch push plate is equipped with ball bearings along its forward and backward movement path, the housing has a cavity for the ball bearings to protrude and move up and down, and a micro switch is provided above the ball bearings, the micro switch being connected in series with the motor.
[0023] In this design, when the clutch push plate moves backward, the ball bearings rise and fall, the micro switch is activated, and the circuit containing the motor is disconnected.
[0024] The beneficial effects of this utility model are as follows: the first transmission hole and the second transmission hole convert the swing of the swing block and the eccentric shaft into the forward and backward movement of the drive plate and the clutch push plate. When unlocking, the drive plate drives the driven block to move backward through the first elastic element, and the driven part separates from the clutch push plate, or the clutch push plate abuts against the front side of the driven part, driving the driven block to move backward, and the first elastic element deforms accordingly.

[0038] See appendix Figure 1-7 An embodiment of this invention provides an electrically controlled lock with mechanical unlocking, comprising a housing 1. The housing 1 contains a lock cylinder 2, a motor 4, a driven block 7, a drive plate 10, and a clutch push plate. The lock cylinder 2 is rotatably mounted with its rotation center line extending vertically. The lock cylinder 2 is connected to a swing block 3. The lock cylinder 2 has a key insertion hole 21. The lock cylinder 2 is connected to a locking part 24, which abuts against the rear side of a locking block 25. A second elastic element 26 is provided between the locking block 25 and the housing 1.
[0039] The motor 4 is positioned below the driven block 7 in a left-right direction. The motor 4 is connected to a worm gear, which meshes with a helical gear. An intermediate gear is coaxially arranged with the helical gear, and the intermediate gear meshes with a driven gear 23. The driven gear 23 is coaxially arranged with the drive wheel 5. The drive wheel 5 is rotatable, and its rotation center line extends vertically. The drive wheel 5 is provided with an eccentric shaft 6, which extends into the first transmission hole 11. The first transmission hole 11 extends in a left-right direction. The drive wheel 5 is located behind the driven block 7.
[0040] The driven block 7 is provided with a locking tongue 8 on its front side, the driven block 7 is provided with a driven part 9, and a third elastic element 27 is provided between the housing 1 and the driven block 7. The third elastic element 27 is sleeved on the locking tongue 8.
[0041] The drive plate 10 is provided with a first transmission hole 11. The drive plate 10 is moved back and forth. The driven block 7 is provided with grooves 17 arranged opposite each other in the vertical direction. The drive plate 10 is provided with a first through hole 18. The groove wall of the groove 17 and the hole wall of the first through hole 18 together form the front cavity wall and the rear cavity wall of the mounting cavity 16. The front hole wall and the rear hole wall of the first through hole 18 are provided with mounting posts 19 for the first elastic element 12 to be sleeved. The first elastic element 12 is provided in the mounting cavity 16 along the front and rear direction.
[0042] The clutch push plate is provided with a second transmission hole 14 and a clutch hole 15. The clutch push plate is arranged to move back and forth. The clutch hole 15 allows the driven part 9 to extend into and move back and forth relative to the clutch push plate. The hole wall of the clutch hole 15 cooperates with the front side of the driven part 9. The second transmission hole 14 allows the swing block 3 to extend into and swing. The hole wall of the second transmission hole 14 cooperates with the rear side of the swing block 3. The lock cylinder 2 is located behind the driven part 9.
[0043] In this embodiment, the driven block 7 moves forward to lock and moves backward to unlock. When mechanically unlocking, the key is inserted into the lock cylinder 2 to drive the swing block 3 to swing. The swing block 3 abuts against the clutch push plate, causing the clutch push plate to move backward. The clutch push plate abuts against the driven part 9, hooking the driven block 7 to move backward. The first elastic element 12 is compressed. When the start button is pressed for electronic unlocking, the motor 4 drives the driven gear 23 to rotate through the helical gear and the intermediate gear, driving the drive wheel 5 to rotate. The eccentric shaft 6 swings, causing the drive plate 10 to move backward. The first elastic element 12 is compressed and then stretched.
[0044] After mechanical unlocking, the first elastic element 12 and the third elastic element 27 exert a forward thrust on the driven block 7 and the clutch push plate, while the elastic force of the second elastic element 26 exerts a backward thrust on the locking block 25 and the lock cylinder 2. The two are balanced. When locked, the elastic force of the third elastic element 27 is balanced with the elastic force of the second elastic element 26. Alternatively, other locking structures can be used to fix the position of the lock cylinder 2. After electronic unlocking, the resistance formed by gear meshing is balanced with the third elastic element 27. The housing 1 guides the forward and backward movement of the driven block 7, the drive plate 10, and the clutch push plate. The drive plate 10 extends from the side into the groove 17 of the driven block 7. The clutch hole 15 is connected to the second transmission hole 14.
[0045] In other alternative embodiments, the drive plate 10 is disposed on the front side of the driven block 7.
[0046] See appendix Figure 8 The clutch push plate is equipped with ball bearings 28 on its forward and backward movement path. The housing 1 is provided with a cavity 20 for the ball bearings 28 to be exposed and raised and lowered. A micro switch 22 is provided above the ball bearings 28. The micro switch 22 is connected in series with the motor 4.
[0047] In this embodiment, the clutch push plate moves backward, and the ball 28 can separate from the rear wall of the clutch hole 15 or the rear wall of the second transmission hole 14, thereby generating a downward stroke, causing the micro switch 22 to extend, and the circuit containing the micro switch 22 and the motor 4 to be disconnected. When the start button is pressed, the motor 4 will not move. A support plate is provided below the clutch push plate to support the separated ball 28 and the clutch push plate, and can also limit the backward movement of the driven part 9.
[0048] In other alternative implementations, the micro switch 22 can be designed to be connected in parallel with the motor 4, and the micro switch 22 can be retracted to short-circuit the circuit containing the motor 4.
[0049] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
