Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle anti-theft locks, in particular to a self-resetting battery lock. Background Art

[0002] Electric vehicles and power-assisted bicycles have become a very important means of transportation in people's daily work and life. Due to their size and weight, electric vehicles and power-assisted bicycles are difficult to carry with you, so people need to store them under office buildings or in temporary parking spots in the community. However, the entire vehicle or battery is often stolen, causing property losses to users. As an anti-theft demand, battery locks are currently commonly installed on electric vehicles and power-assisted bicycles. The battery lock can be used to lock the electric vehicle after parking, and the battery position of the electric vehicle can also be locked to prevent the electric vehicle and its battery from being stolen.

[0003] The existing battery lock mainly includes a lock body, a motor module, and a lock core structure. The motor module and the lock core are connected through a gear assembly. The battery of the electric vehicle provides working power for the motor module of the battery lock, thereby driving the battery lock to unlock or lock. When the shared electric vehicles on the market are low on power, it is usually necessary to replace the battery. The battery lock is unlocked to pop up the seat cushion position, and then the battery is taken out of the battery compartment. Since the battery lock will be powered off and become invalid after the battery is removed, the lock core will be stuck in the unlocked position and cannot move. The battery needs to be replaced to drive the battery lock to be locked again. During this process, the battery lock needs to wait for a few seconds before the lock core can be driven back to its position. In addition, there is a large bite force between the gears and there is a motion stroke, which is prone to jamming. The motor load is relatively large, resulting in a long delay and jamming in the locking of the battery lock after the battery is replaced. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problems of long locking delay and jamming phenomenon and relatively large motor load in the battery lock in the prior art after replacing the battery, thereby providing a self-resetting battery lock with a simple structure, reduced motor load and capable of automatically resetting and locking.

It further includes a driving cam rotatably arranged in the installation cavity under the drive of the electric control device and a travel switch arranged on the movement path of the driving cam. The driving cam pushes the lock tongue to move during rotation. After the driving cam pushes the lock tongue to the unlocking position, it separates from the lock tongue and stops when it continues to rotate and contacts the travel switch. The reset spring drives the lock tongue to reset to the locked position when the driving cam separates from the lock tongue.

[0006] As a preferred solution, the reset spring extends along the moving direction of the lock tongue in the installation cavity. A first positioning groove is arranged at the other end of the lock tongue, and a second positioning groove opposite to the first positioning groove is arranged on the side wall of the installation cavity.

[0009] As a preferred solution, a guiding structure is arranged between the lock tongue and the installation cavity. The guiding structure includes a guiding chute extending along the moving direction of the lock tongue in the installation cavity and a guiding slide table arranged on the bottom side of the lock tongue and slidably connected to the guiding chute. The relief groove is arranged on one side of the guiding slide table.

[0010] As a preferred solution, the electric control device includes an electric control housing fixedly connected to the lock housing, and a motor, a gear assembly and a control board arranged in the inner cavity of the electric control housing. The motor and the travel switch are respectively electrically connected to the control board. The motor is connected to the driving cam through the gear assembly. The inner cavity of the electric control housing and the installation cavity are sealed and separated.

[0011] As a preferred solution, the installation cavity includes an installation groove arranged on the outer side wall of the electric control housing. The driving cam and the travel switch are respectively arranged in the installation groove. The electric control housing is provided with a wire passing hole communicating the inner cavity and the installation groove. The wire connecting the control board and the travel switch passes through the wire passing hole, and a sealing sleeve in sealing cooperation with the wire is arranged at the position of the wire passing hole.

[0012] As a preferred solution, an emergency unlocking structure for connecting the lock tongue is provided between the lock housing and the electric control device, and the emergency unlocking structure drives the lock tongue to move from the locked position to the unlocked position under the action of an external force.

[0013] As a preferred solution, the emergency unlocking structure includes an emergency operation shaft rotatably arranged in the installation cavity, and a push rod eccentrically arranged at one end of the emergency operation shaft.

The emergency operation shaft is perpendicular to the lock tongue, and the push rod extends and is connected in the push groove.

[0014] As a preferred solution, the other end of the operation shaft extends out of the lock housing and is provided with a detachable key handle.

[0015] The technical solution of the present utility model has the following advantages compared with the prior art:

[0016] 1. In the self-resetting battery lock provided by the present utility model, by arranging a reset spring connecting the lock tongue in the installation cavity, the lock tongue has a tendency to move upward to the locked position under the elastic force applied by the reset spring. The driving cam drives the lock tongue to move from the locked position to the unlocked position under the drive of the electric control device. During this process, the reset spring is compressed and stores energy by the lock tongue, thereby realizing the unlocking operation of the battery lock. Immediately afterwards, the driving cam will continue to rotate and separate from the lock tongue after unlocking, and will not stop rotating until it touches the travel switch. After the lock tongue separates from the driving cam, it will quickly reset to the locked position under the action of the reset spring, realizing the relocking of the battery lock. The battery lock adopting the present technical solution will complete the relocking process again within a short time after unlocking, thereby realizing the function of automatic reset and relocking. This kind of battery lock is suitable for the battery anti-theft protection of electric vehicles, and effectively overcomes the problems of locking delay and jamming of existing battery locks after battery replacement, reduces the load on the motor, improves work efficiency, enhances the product performance, and ensures the safety and reliability of product use.

[0017] 2. In the self-resetting battery lock provided by the present utility model, by providing a first positioning groove at the other end of the lock tongue and a second positioning groove corresponding to the side wall of the installation cavity, the two ends of the reset spring are respectively arranged in the two positioning grooves. The two positioning grooves play a role in positioning and installing the reset spring in the installation cavity. The elastic force direction of the reset spring designed in this way is parallel to the moving direction of the lock tongue, and the force is more concentrated, ensuring the accuracy and reliability of the reset spring driving the lock tongue to reset and move to realize locking.

[0018] 3. In the self - resetting battery lock provided by the present utility model, a relief groove with an L - shaped structure is provided on the bottom side of the locking tongue, and a convex platform portion is provided on the groove wall of the relief groove. The movement trajectory of the convex platform portion intersects with the movement trajectory of the driving cam. Such a design enables the protrusion of the driving cam to rotate into the relief groove and cooperate with the convex platform portion in contact, thereby pushing the locking tongue from the locked position to the unlocked position to cooperate and achieve the unlocking process. Moreover, after the driving cam pushes the locking tongue to the unlocked position, it will continue to rotate away from the convex platform portion, which not only cancels the thrust acting on the locking tongue but also moves away from the movement path of the locking tongue, ensuring that the locking tongue can quickly automatically reset and lock under the spring force, enabling the battery lock to complete an unlocking and locking action within a short time. Finally, the movement stroke of the driving cam is limited by a travel switch, with reasonable design and reliable cooperation.

[0019] 4. In the self - resetting battery lock provided by the present utility model, when the battery lock fails and cannot be electrically unlocked, manual unlocking is achieved through an emergency unlocking structure. Specifically, by rotating the emergency operation shaft, the emergency operation shaft drives the locking tongue to move inwardly towards the through - hole through a push rod, thereby driving the locking tongue from the locked position to the unlocked position, and realizing the emergency unlocking function of the battery lock.

[0032] Embodiment

[0033] The following is a specific description of this embodiment with reference to the accompanying drawings:

[0034] The present utility model provides as Figures 1 - 6A self-resetting battery lock as shown is used to lock the battery of an electric vehicle. It includes a lock housing 1, an electric control device 2 installed in the lock housing 1, an installation cavity 3 formed between the lock housing 1 and the electric control device 2, and a lock tongue 4 reciprocally movably arranged in the installation cavity 3. The lock housing 1 is provided with a through hole through which one end of the lock tongue 4 can extend. During the reciprocating movement of the lock tongue 4, it has a locked position where it extends outside the through hole and an unlocked position where it retracts into the through hole. A return spring 6 connecting the lock tongue 4 is arranged in the installation cavity 3, and this return spring 6 applies an elastic force to the lock tongue 4 to move it towards the outside of the through hole. It also includes a driving cam 5 rotatably arranged in the installation cavity 3 driven by the electric control device 2, and a travel switch 7 arranged on the movement path of the driving cam 5. The travel switch 7 is electrically connected to the electric control device 2 and sends a signal to stop the electric control device 2 when triggered by the driving cam 5. During the rotation of the driving cam 5, it pushes the lock tongue 4 to move, specifically pushing the lock tongue 4 from the locked position to the unlocked position. Among them, after the driving cam 5 pushes the lock tongue 4 to the unlocked position, it separates from the lock tongue 4 and continues to rotate until it contacts the travel switch 7 and then stops. The return spring 6 drives the lock tongue 4 to reset to the locked position when the driving cam 5 separates from the lock tongue 4.

[0035] The above implementation manner is the core technical solution of this embodiment. By arranging a return spring 6 connecting the lock tongue 4 in the installation cavity 3, the lock tongue 4 has a movement tendency to move towards the locked position under the elastic force applied by the return spring 6. The driving cam, driven by the electric control device 2, pushes the lock tongue 4 from the locked position to the unlocked position. During this process, the return spring 6 is compressed and stores energy by the lock tongue 4, thus realizing the unlocking operation of the battery lock. Immediately afterwards, after the driving cam 5 completes the unlocking, it will continue to rotate and separate from the lock tongue 4 until it contacts the travel switch 7 and then stops rotating. After the lock tongue 4 separates from the driving cam 5, it will quickly reset to the locked position under the action of the return spring, realizing the relocking of the battery lock. The battery lock adopting this technical solution will complete the locking process again within a short time after unlocking, thus realizing the function of automatic reset and locking. This kind of battery lock is applicable to the anti-theft protection of the battery of an electric vehicle, effectively overcomes the problems of locking delay and jamming existing in the existing battery lock after replacing the battery, reduces the load on the motor, improves work efficiency, enhances the use performance of the product, and ensures the safety and reliability of product use.

[0036] Such as Figures 2 - 3As shown in the figure, the return spring 6 is arranged in the installation cavity 3 along the moving direction of the locking tongue 4. The other end of the locking tongue 4 is provided with a first positioning groove 41. On the side wall of the installation cavity 3, a second positioning groove 31 opposite to the first positioning groove 41 is provided. The two ends of the return spring 6 are respectively arranged in the first positioning groove 41 and the second positioning groove 31. With this structural arrangement, the return spring 6 is positioned and installed in the installation cavity 3 through the two positioning grooves. In this way, the elastic force direction of the designed return spring 6 is parallel to the moving direction of the locking tongue 4, and the force is more concentrated, ensuring the accuracy and reliability of the return spring 6 driving the locking tongue 4 to reset and move to lock.

[0037] The following will combine Figures 3 - 6 to make a detailed description of the specific structures of the driving cam and the locking tongue:

[0038] A boss portion 42 cooperating with the driving cam 5 is provided on the bottom side of the locking tongue 4. The protruding portion of the driving cam 5 cooperates with and contacts or separates from the boss portion 42. Further preferably, the driving cam 5 is rotatably arranged on the bottom side of the locking tongue 4. An L-shaped structure relief groove 43 is provided on the bottom side of the locking tongue 4. The boss portion 42 is arranged on the groove wall of the relief groove 43. The movement trajectory of the boss portion 42 intersects with the movement trajectory of the driving cam 5. With this design, the protruding portion of the driving cam 5 can rotate into the relief groove 43 and cooperate with and contact the boss portion 42, thereby pushing the locking tongue 4 to move from the locked position to the unlocked position to cooperate and achieve the unlocking process. Moreover, after the driving cam 5 pushes the locking tongue 4 to the unlocked position, it will continue to rotate away from the boss portion 42. In this way, not only the thrust acting on the locking tongue 4 is withdrawn, but also it is away from the movement path of the locking tongue 4, ensuring that the locking tongue 4 can quickly and automatically reset and lock by means of the spring force, realizing that the battery lock completes an unlocking and locking action in a short time, and the movement stroke of the driving cam 5 is limited by the travel switch 7. The design is reasonable and the cooperation is reliable.

[0039] To ensure the reliability of the locking or unlocking movement of the locking tongue 4, a guiding structure is provided between the locking tongue 4 and the installation cavity 3. The guiding structure includes a guiding chute 32 extending in the installation cavity 3 along the moving direction of the locking tongue 4, and a guiding slide 44 arranged on the bottom side of the locking tongue 4 and slidably connected to the guiding chute 32. The relief groove 43 is arranged on one side of the guiding slide 44. The cooperation between the guiding slide 44 and the guiding chute 32 plays a guiding role in the movement of the locking tongue to prevent the locking tongue from shifting during the reciprocating movement, and the installation stability is good.

[0040] The following will combine Figures 1 - 3 to make a detailed description of the specific setting method of the electronic control device 2;

[0041] The electric control device 2 includes an electric control housing 21 fixedly connected to the lock housing 1, and a motor, a gear assembly 22 and a control board 23 disposed in the inner cavity of the electric control housing 21. The motor and the travel switch 7 are respectively electrically connected to the control board 23. When the control board receives an instruction signal sent by the travel switch, it can control the motor to stop rotating. The motor is connected to the driving cam 5 through the gear assembly 22. The gear assembly 22 is composed of a plurality of transmission gears. The driving cam 5 is coaxially linked with the last-stage gear of the gear assembly 22, so as to transmit the power of the motor to the driving cam through the way of gear transmission. Finally, the driving cam drives the lock tongue 4 to perform an unlocking operation.

[0042] The installation cavity 3 is a closed space formed by assembling the electric control housing 21 and the lock housing 1. In order to ensure the sealing performance inside the electric control housing 21, the inner cavity of the electric control housing 21 and the installation cavity are sealed and separated. Among them, the installation cavity 3 includes an installation groove provided on the outer side wall of the electric control housing 21. The driving cam 5 and the travel switch 7 are respectively disposed in the installation groove. The button part of the travel switch 7 is located on the rotation path of the driving cam 5. When the travel switch 7 is pressed by the driving cam 5, it sends an instruction signal to the control board 23. After receiving the instruction signal, the control board 23 controls the motor and the driving cam 5 to stop rotating. A wire passing hole 24 communicating with the inner cavity is provided in the installation groove. Since the travel switch and the control board are connected by a wire, the wire connecting the control board 23 and the travel switch 7 passes through the wire passing hole 24, and a sealing sleeve (the sealing sleeve is not shown in the drawing) that is hermetically matched with the wire is provided at the position of the wire passing hole 24, so as to ensure the sealing performance at the position of the wire passing hole.

[0043] In this embodiment, an emergency unlocking structure 8 connecting the lock tongue 4 is provided between the lock housing 1 and the electric control device 2. The emergency unlocking structure 8 drives the lock tongue 4 to move from the locked position to the unlocked position under an external force. Refer to Figures 3 - 5As shown in the figure, the emergency unlocking structure 8 includes an emergency operation shaft 81 rotatably arranged in the installation cavity 3, and a push rod 82 eccentrically arranged at one end of the emergency operation shaft. The emergency operation shaft 81 is perpendicular to the lock tongue 4. A push groove 45 cooperating with the push rod 82 is provided on one side wall of the lock tongue 4. The push rod 82 extends and is connected in the push groove 45. The other end of the operation shaft extends out of the lock housing 1 and is provided with a detachable key handle 83. The push rod 82 is designed in an arc structure. When the emergency operation shaft 81 is in the initial position, the push rod 82 is driven to be in the push groove 45. At this time, the push rod will not affect the normal locking and unlocking movement of the lock tongue. Only when the emergency operation shaft 81 rotates during unlocking, the push rod 82 is driven to abut against one end of the push groove, thereby driving the lock tongue 4 to move towards the unlocking position. The advantage of this design is that when the battery lock fails and cannot be electrically unlocked, the manual unlocking is realized through the emergency unlocking structure 8. Specifically, by rotating the emergency operation shaft 81, the emergency operation shaft 81 drives the lock tongue 4 to move towards the inner side of the through hole through the push rod 82, thereby driving the lock tongue 4 to move from the locked position to the unlocked position, realizing the emergency unlocking function of the battery lock and ensuring the safety of product use.

[0044] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
