Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a secondary lock, a battery holder, a power battery and a frame. Background Art

[0002] The battery is often locked in an electric bicycle to prevent the battery from being stolen, and the primary lock can completely release the battery with just one unlocking action. When the battery is taken out from under the tube of the electric bicycle, the battery may fall and be damaged if the lock is not opened carefully. Therefore, in order to reduce the damage caused by the battery falling and further improve the user experience, a secondary lock is often used to lock the battery of the electric bicycle, such as the patents with publication numbers DE102021102920A1, US20190165347A1, and public The patent with opening number TW202112601A, the patent with publication number JP2021068693A, the patent with publication number CN218677417U, the patent with publication number CN211008039U and the patent with publication number CN210403841U all use a two-level lock to lock the battery of the electric bicycle. Specifically, one unlocking is to twist the lock head with a lock tongue set on the base, that is, the key is used to twist the lock core to drive the lock tongue to move away from the battery to complete the one-time release of the battery.

[0003] However, in the above-mentioned secondary lock, the structure for realizing the secondary release of the battery still has the following problems:

[0004] The first is that the secondary release of the battery is completed by pressing or toggling other structures on the base, such as moving the secondary lock tongue or the clamping member to separate from the battery. In this way, the base needs to redesign related parts for different secondary unlocking methods, which has poor compatibility. In addition, the additional structure causes the base to occupy a larger space.

[0005] The second is: the secondary release of the battery is completed through other structures on the battery, such as pressing or sliding the movable part, retaining elements, etc. to move them away from the base. In this way, the battery needs to give up part of its volume for secondary unlocking, which has poor adaptability and a large difference between the primary and secondary release methods of the battery, affecting the user experience.

[0054] The present application provides a secondary lock. In order to better understand the secondary lock of the present application, the secondary lock of the present application is further explained below:

[0055] Please also read Figure 1 to Figure 2 A secondary lock 10 of one embodiment includes a lock tongue elastic body 100, a lock body 200, a lock tongue 300 and a lock core 400. The lock tongue elastic body 100 is connected to the lock body 200, and the lock tongue 300 is connected to the telescopic end of the lock tongue elastic body 100, so that the lock tongue 300 is telescopically connected to the lock body 200, and one end of the lock tongue 300 away from the lock tongue elastic body 100 at least partially protrudes from the lock body 200, the lock core 400 is movably connected to the lock body 200, and the lock core 400 is connected to the lock tongue 300, so that the lock core 400 drives the lock tongue 300 to move intermittently twice in a direction close to the lock tongue elastic body 100. When the lock core 400 drives the lock tongue 300 to move toward the direction close to the lock tongue elastic body 100 for the first displacement, the lock core 400 and the lock body 200 are unlocked once, and the lock tongue 300 and the battery are always in contact; when the lock core 400 drives the lock tongue 300 to move toward the direction close to the lock tongue elastic body 100 for the second displacement, the lock core 400 and the lock body 200 are unlocked for the second time, so that the lock tongue 300 and the battery are separated from the battery. Further, the lock tongue 300 is restricted in the lock body 200. Further, the lock tongue 300 is at least partially engaged in the lock body 200 and can be slidably connected to the lock body 200.

[0056] The above-mentioned secondary lock 10 makes the lock tongue elastic body 100 connected to the lock body 200, and the lock tongue 300 is connected to the telescopic end of the lock tongue elastic body 100, so that the lock tongue 300 is telescopically connected to the lock body 200. In this way, the lock tongue 300 spring plays a role in supporting the lock tongue 300 to extend out of the lock body 200, thereby achieving the stopping stability of the lock tongue 300 for the battery, and the lock tongue 300 can extend and retract relative to the lock body 200, and the lock tongue 300 retracts into the lock body 200, which better realizes The battery is released twice effectively, and the lock tongue 300 compresses the lock tongue 300 elastic member to generate elastic force storage. At the same time, after the lock tongue 300 retracts, it can be reset under the elastic force of the lock tongue elastic body 100 and extend out of the lock body 200, so that when the battery is locked, the lock tongue elastic body 100 can automatically reset after compressing the battery to complete the battery stop, which effectively improves the convenience of battery locking. The lock core 400 is movably connected to the lock body 200, and the lock core 400 is connected to the lock tongue 300. , so that the lock core 400 drives the lock tongue 300 to move twice discontinuously in the direction close to the lock tongue elastic body 100. When the lock core 400 drives the lock tongue 300 to move in the direction close to the lock tongue elastic body 100 for the first displacement, the lock core 400 and the lock body 200 are unlocked once, and the lock tongue 300 is always in contact with the battery; when the lock core 400 drives the lock tongue 300 to move in the direction close to the lock tongue elastic body 100 for the second displacement, the lock core 400 and the lock body 200 are unlocked for the second time, so that the lock tongue 300 is separated from the battery, that is, the two unlocking of the battery are completed by the secondary lock 10, and there is no need to design other structures on the base or the battery to complete the second unlocking of the battery, so that the base only needs to complete the setting of the secondary lock 10, which indirectly improves the compatibility and adaptability of the base, and realizes the simplification of the structure of the base, effectively realizes the miniaturization of the base, and the secondary lock 10 has the same unlocking method for the battery twice, thereby effectively improving the user experience.

[0057] It should be noted that the secondary locks currently used for battery locking of electric bicycles are mostly unlocked by using a lock tongue lock to release the battery once, and then releasing the battery a second time by pressing or toggling other structures on the base, or by pressing or toggling the lock tongue through other structures on the base to release the battery a second time. This complicates the structure of the base, and the user needs to operate at different positions to achieve the secondary release of the battery. In the present application, the lock core drives the lock tongue to move in two stages of displacement to achieve the secondary release of the battery. There is no need to structurally design the base, and only the lock body needs to be installed on the base. There is no need for the user to operate at different positions, and the user only needs to operate the lock core to achieve the secondary release of the battery, which effectively improves the compatibility and adaptability of the secondary lock and effectively improves the user experience.

[0058] Please also read Figure 2 , Figure 4 and Figure 6 In some embodiments, the lock tongue elastic body 100 is at least partially embedded in the lock tongue 300. In other embodiments, the lock tongue elastic body is sleeved on the lock tongue, and the lock tongue elastic body at least partially protrudes from the lock tongue and abuts against the lock body, thereby achieving a stable arrangement of the lock tongue elastic body on the lock tongue.

[0059] Please also read Figures 4 to 6 In one embodiment, the lock core 400 is rotatably connected to the lock body 200, and the rotation centerline of the lock core 400 intersects with the extension and contraction direction of the lock tongue 300. Further, a swivel 500 is convexly provided at the end of the lock core 400 close to the lock tongue 300, and the swivel 500 is arranged away from the rotation centerline of the lock core 400, and the lock core 400 and the lock tongue 300 are arranged in a avoidance manner. Further, the swivel 500 and the lock tongue 300 are arranged in a avoidance manner, and a linkage body 600 is convexly provided on a side of the lock tongue 300 close to the lock core 400, and the swivel 500 at least partially abuts against a side of the linkage body 600 away from the lock tongue elastic body 100. When the lock core 400 rotates on the lock body, the lock core drives the swivel to rotate eccentrically, so that the swivel pushes the linkage body to move twice in a direction close to the lock tongue elastic body. Furthermore, the swivel 500 includes a main body 510 and a connecting portion 520, the main body 510 is connected to the end of the lock core 400 close to the lock tongue 300 through the connecting portion 520, the main body 510 is set away from the rotation center line of the lock core 400, the main body 510 and the connecting portion 520 are both set to avoid the lock tongue 300, the main body 510 at least partially abuts against the side of the linkage body 600 away from the lock tongue elastomer 100, and the lock core 400 drives the lock tongue 300 to move intermittently twice in the direction close to the lock tongue elastomer 100 through the main body 510, thereby better ensuring the effectiveness of the lock core 400 driving the lock tongue 300 to move in the direction close to the lock tongue elastomer 100, and better realizing the driving of the lock tongue 300 to move twice in the direction close to the lock tongue elastomer 100. It can be understood that if the lock tongue moves twice intermittently, it can be achieved by controlling the intermittent rotation of the lock core, such as when the lock core rotates less than 180°, the lock tongue is driven to move the first displacement, and then when the lock core rotates less than 180° again, and the two rotations do not exceed 180°, the lock tongue is driven to move the second displacement. Furthermore, after the lock core is paired with the key, force is applied to the key to drive the lock core to rotate.

Further, a sliding groove 401b is provided on the sliding area 401, and the sliding groove 401b is arranged around the rotation center line of the lock core 400, and a portion of the lock body 200 is slidably arranged at the sliding groove 401b. It can be understood that in some other embodiments, a slide rail can be provided in the sliding area for sliding with the lock body, and the sliding area is set as a sliding groove, that is, while simplifying the structure of the lock core, it better plays a role in limiting the rotation of the lock core on the lock body, and better ensures the stability of the lock core driving the lock tongue to move, and better limits the rotation angle of the lock core 400, thereby better ensuring that the lock core 400 drives the lock tongue 300 to move twice toward the direction close to the lock tongue elastomer 100 through the swivel 500. Effective control.

[0062] Please also read Figure 2 , Figure 3 and Figure 5In one embodiment, the sliding area 401 includes two interconnected sliding sub-areas 401a, both of which are arranged around the rotation centerline of the lock core 400, and the two sliding sub-areas 401a are arranged in sequence along the rotation centerline direction of the lock core 400, and the projections of the two sliding sub-areas 401a on a plane perpendicular to the rotation centerline of the lock core 400 overlap at most, and the lock body 200 is partially slidably arranged at any sliding sub-area 401a, and the two sliding sub-areas 401a together surround the lock core 400 at most half a circle. Further, the lock core 400 and the lock tongue 300 are arranged in a avoidance position, the lock core 400 is slidably arranged on the lock body 200, at least one of the lock core 400 and the lock tongue 300 is slidably connected to the swivel 500, and the sliding direction of the lock core 400 and / or the lock tongue 300 is parallel to the rotation centerline of the lock core 400. Furthermore, when part of the lock body 200 is located in the sliding sub-area 401a away from the lock tongue 300, the lock core 400 is rotated relative to the lock body 200, so that the part of the lock body 200 slides from one end of the corresponding sliding sub-area 401a away from the other sliding sub-area 401a to the other end, and the swivel 500 pushes the linkage body 600 to move once in the direction close to the lock tongue elastic body 100, and the lock tongue elastic body 100 is compressed; when part of the lock body 200 is located in the sliding sub-area 401a away from the lock tongue 300 and is located in the corresponding sliding sub-area 401a close to the other sliding sub-area When the end of the movable area 401a is reached, the lock core 400 is pressed to move toward the lock body 200 so that the lock core 200 slides into another sliding area 401a; when part of the lock body 200 is located in the sliding area 401a close to the lock tongue 300, the lock core 400 is rotated relative to the lock body 200 so that part of the lock body 200 slides from one end of the corresponding sliding area 401a close to the other sliding area 401a to the other end, and the swivel 500 pushes the linkage body 600 to move a second displacement in the direction close to the lock tongue elastomer 100, and the lock tongue elastomer 100 is compressed again.It can be understood that when the lock body 200 needs to slide away from one sliding sub-area 401a and slide into the other sliding sub-area 401a, it is necessary to control the lock core 400 to slide relative to the lock body 200 along its own rotation centerline direction to achieve this. Specifically, the lock tongue 300 moves to the farthest end under the elastic force of the lock tongue elastic body 100, that is, when it moves to the maximum elongation of the lock tongue elastic body 100, the lock core 400 rotates, and a part of the lock body 200 starts to slide at an end of a sliding sub-area 401a close to the lock tongue 300 and away from the other sliding sub-area 401a. Synchronously, the lock core 400 drives the swivel 500 to rotate, and then the swivel 500 drives the lock tongue 300 to move in the direction close to the lock tongue elastic body 100 until the lock body 200 slides to the other end of the sliding sub-area 401a.
