In order that the above-recited objects, features and advantages of the present disclosure may be more clearly understood, a detailed description of the present disclosure will be rendered by reference to the appended drawings and appended drawings. In addition, embodiments of the present application and features of the embodiments may be combined with each other without conflict. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, and the described embodiments are merely some, rather than all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure are intended to be within the scope of this disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

In various embodiments, for ease of description and not limitation of the present disclosure, the term "coupled" as used in the specification and claims of this disclosure is not limited to a physical or mechanical connection, but may include an electrical connection, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship is changed accordingly.

Fig. 1 is a schematic structural view of a split locking device. As shown in fig. 1, the split locking device includes a split locking mechanism 1 and a driving device 2. The lock mechanism 1 may be provided in any one of the battery box, the vehicle-mounted area of the vehicle body, and the battery rack, and the lock mechanism 1 locks or unlocks the battery box to or from the vehicle-mounted area of the vehicle body or the battery rack by a lock operation or an unlock operation of the lock mechanism. The driving device 2 is used for movably connecting the locking mechanism 1, and when unlocking or locking operation is required, the locking mechanism 1 is locked or unlocked by the driving device 2 abutting against the locking mechanism 1. In the present embodiment, the lock mechanism 1 is a rotary lock mechanism 1, and after the lock mechanism 1 is abutted by the driving device 2, the components of the lock mechanism 1 are driven to rotate to lock or unlock.

Fig. 2 is a schematic structural view of the split lock mechanism 1 in an exploded state, and fig. 3 is a schematic sectional structural view of the split lock mechanism 1. As shown in fig. 2 and 3, the split locking mechanism 1 includes a lock body and a transmission assembly 20. The lock body is used for locking or unlocking other components, and the transmission assembly 20 is used for butting the driving device 2, so that the lock body can be driven to act to realize unlocking or locking.

In this embodiment, the lock body includes a first pull shaft 10, and is unlocked or locked by driving the first pull shaft 10 to rotate. Illustratively, in this embodiment, the first pull shaft 10 has a generally "T" shaped structure, and one or more detents 11 are provided at an upper portion thereof. During unlocking or locking, the first pull shaft 10 is rotated so that the bayonet 11 rotates to have different angles relative to the lock head (not shown in the figure), and thus, when the first pull shaft 10 rotates to an unlocking position (for example, to a position with an angle of 0 degree), the bayonet 11 corresponds to a special-shaped hole of the lock head, so that the lock head can be separated from the special-shaped bayonet to complete locking operation; when the first pull shaft 10 is rotated to a locking position (for example, rotated to a position with an angle of 90 degrees), the locking pin 11 is rotated to a position crossing the profiled clamp, for example, a position perpendicular to the profiled hole, so that the lock head can be hooked by the locking pin 11 to complete the locking action.

The conventional lock body directly abuts against the driving device 2 through the first pull shaft 10, and the rotation of the first pull shaft 10 is directly obtained through the driving device 2. However, the inventors have found that in implementing the locking mechanism 1, since the locking mechanism 1 and the driving device 2 are generally manufactured by different manufacturers, there is a need to provide different types of first pull shafts 10 corresponding to different driving devices 2, resulting in numerous types of locking mechanisms 1, and high production and maintenance costs. For this reason, in this application, through setting up the power transmission that drive arrangement 2 was transferred to drive arrangement 20, when using, to different drive arrangement 2 change corresponding drive arrangement 20 can, and to lock body part then can realize mass production to can effectively reduce locking mechanism 1's model quantity.

Fig. 4 is a schematic structural view of the transmission assembly 20. As shown in fig. 3 and 4, the transmission assembly 20 includes a base 21, a second pull shaft 22, and a rotation locking member. The base 21 is used for accommodating the first pull shaft 10 and the second pull shaft 22, and particularly accommodating the connection part of the first pull shaft 10 and the second pull shaft 22, so as to protect and support the first pull shaft 10 and the second pull shaft 22. The second pull shaft 22 is used for driving the first pull shaft 10 to rotate by transmitting the power of the driving device 2, and the rotation locking component is connected with the second pull shaft 22 to play a role of secondary locking and prevent the second pull shaft 22 from rotating by mistake.

Fig. 5 is a schematic structural view of the second pull shaft 22. As shown in fig. 3 and 5, the second pull shaft 22 has a generally cylindrical structure, one end is detachably connected to the first pull shaft 10, and the other end is used for abutting against the driving device 2 to rotate the first pull shaft 10. Specifically, one end (i.e., the top end) of the second pull shaft 22 has a step, and the first pull shaft 10 is coaxially abutted by the step, so that the first pull shaft 10 and the second pull shaft 22 can rotate synchronously. The side surface of the second pull shaft 22, which is used for connecting with the end part of the driving device 2, is provided with a clamping groove 223 extending along the length direction, and the driving device 2 is embedded into the clamping groove 223 to drive the second pull shaft 22 to rotate. In this embodiment, the bottom of the second pull shaft 22 may be a cylindrical structure, or may be a rectangular or other irregularly shaped cylindrical structure. For convenience of description, the side surface of the bottom of the second pull shaft 22 is referred to as a "lower end surface", and the surface of the bottom of the second pull shaft 22 parallel or substantially parallel to the length direction is referred to as a "side surface". The clamping groove 223 is arranged on the side surface in an open way, and the length direction of the clamping groove 223 is preferably parallel or approximately parallel with the length direction of the second pull shaft 22. Thus, in the winter icing scene, the driving device 2 can remove the ice cubes in the clamping groove 223 in the process of extending into the clamping groove 223, so that the problem of docking failure caused by icing in winter is avoided.

Fig. 6 is a schematic structural view of the base 21. As shown in fig. 6, the base 21 has a generally block-shaped structure, and has a cavity 215 therethrough in the middle. In some embodiments, to prevent dust and moisture from entering the lock body, the base 21 may further include an upper cover 211, where the upper cover 211 may be connected to the base 21 by a connection such as a screw or bolt, and function to seal the cavity 215 with the base 21.

The rotation locking means is for locking the second pull shaft 22 to prevent the second pull shaft 22 and the first pull shaft 10 from rotating due to an erroneous operation or vibration. Specifically, the rotation lock mechanism 1 includes an unlocking hole 212, a lock hole 213 and a limit groove 214, and an axial hole 222, a first radial hole 224, a second radial hole 225, and a stopper 26, a stopper 25, a knock pin 23, and an elastic member 24. Wherein the unlocking hole 212, the locking hole 213 and the limiting groove 214 are disposed on the inner wall of the cavity 215 of the base 21, the axial hole 222, the first radial hole 224 and the second radial hole 225 are disposed on the second pull shaft 22, and the knock pin 23 and the elastic member 24 are disposed between the first pull shaft 10 and the second pull shaft 22.

Specifically, as shown in fig. 4 and 6, the unlocking hole 212 and the locking hole 213 are disposed along the circumferential direction on the inner wall of the cavity 215 of the base 21, and as an example, the unlocking hole 212 corresponds to the unlocking position of the second pull shaft 22, the locking hole 213 corresponds to the locking position of the second pull shaft 22, and the angle between the unlocking hole 212 and the locking hole 213 is 90 degrees and is trapped in the inner wall of the cavity 215, but the relative positions of the unlocking hole 212 and the locking hole 213 may be set as required. The unlocking hole 212 and the locking hole 213 may be holes, but may also be grooves extending along the length direction, and a person skilled in the art may determine the specific structures of the unlocking hole 212 and the locking hole 213 according to a processing manner or other factors. The limiting groove 214 is disposed on an inner wall of the cavity 215 of the base 21, extends along the rotation direction of the second pull shaft 22, and has two ends corresponding to the unlocking hole 212 and the locking hole 213, respectively. Specifically, the limiting groove 214 is a groove body extending along the circumferential direction of the cavity 215, and two ends of the limiting groove 214 correspond to the unlocking hole 212 and the locking hole 213 respectively.

As shown in fig. 3 and 5, the second pull shaft 22 is internally provided with an axial hole 222, a first radial hole 224 and a second radial hole 225. In the present embodiment, the axial hole 222 is a blind hole, and the opening extends in the axial direction of the second pull shaft 22 toward the end of the first pull shaft 10. The first radial hole 224 and the second radial hole 225 are provided at the top of the second pull shaft 22, open toward the side of the second pull shaft 22, and the other end extends in the proceeding direction of the second pull shaft 22 and communicates with the axial hole 222.

As shown in fig. 3 and 4, the locking member 25 protrudes from the first radial hole 224 to be inserted into the unlocking hole 212 or the locking hole 213 to lock the rotation of the second pull shaft 22 and the first pull shaft 10. The locking member 25 includes one or more balls, and when the knock pin 23 moves to a position corresponding to the first radial hole 224 in the recess 231, the balls are withdrawn from the unlocking hole 212 or the locking hole 213 to unlock the rotation of the second pull shaft 22. As an example, in the present embodiment, the locking member 25 includes two balls disposed in the first radial hole 224, and the outer diameter is substantially equivalent to the inner diameter of the first radial hole 224.

As shown in fig. 2 and 3, the knock pin 23 is generally rod-shaped, and has a boss protruding in the radial direction at an upper portion thereof, a recess 231 having a smaller radial length than the boss is formed below the boss, and the recess 231 is provided on a side of the knock pin 23 facing the first radial hole 224 for receiving the locking member 25. The ejector pin 23 is movably located in the axial hole 222 of the second pull shaft 22 in the axial direction, and can move back and forth in the axial direction of the axial hole 222 under the action of an external force, so as to push the locking member 25 out of the first radial hole 224 or receive a part of the locking member 25 through the recessed area 231.

When the driving device 2 abuts against the second pull shaft 22, the driving device 2 pushes the ejector pin 23 to move to the concave area 231 corresponding to the first radial hole 224, and the locking piece 25 is separated from the base 21 and moves back to the concave area 231. Specifically, the locking member 25 may protrude from the first radial hole 224 into the unlocking hole 212 or the locking hole 213 under the pushing of the knock pin 23, so that the second pull shaft 22 may be prevented from rotating; in addition, when the recess 231 of the knock pin 23 is located at the position of the first radial hole 224, the locking piece 25 may be partially retracted into the recess 231 so as to be withdrawn from the unlocking hole 212 or the locking hole 213, and at this time, the second pull shaft 22 may be rotated by releasing the blocking of the locking piece 25, thereby achieving the unlocking operation.

Similarly, a limiting member 26 is disposed in the second radial hole 225 and extends into the limiting groove 214 for limiting the rotation angle of the second pull shaft 22. In this embodiment, the stop 26 comprises a ball that is positioned within the second radial hole 225 and partially engages the stop slot 214. In the present embodiment, a part of the stopper 26 is fitted into the stopper groove 214, and the other part is fitted into the second radial hole 225. In the rotation process of the ejector pin 23, the limiting member 26 rotates between the limiting groove 214 and the second radial hole 225, and when the rotation angle of the second pull shaft 22 exceeds the range of the limiting groove 214, the second pull shaft 22 is stopped by the limiting member 26 and cannot rotate, so that the second pull shaft 22 can only rotate within the range of the limiting groove 214, and cannot rotate beyond the range of the limiting groove 214, and thus the rotation range of the second pull shaft 22 can be limited.

In order to reset the knock pin 23, in this embodiment, the rotation locking member further includes an elastic member 24, where the elastic member 24 may be a spring, and is abutted between the knock pin 23 and the first pull shaft 10, so as to reset the knock pin 23, and push the locking member 25 to be inserted into the base 21 through the knock pin 23.

Referring back to fig. 3, in order to improve the sealing performance of the locking mechanism 1, in this embodiment, a sealing ring is disposed in the circumferential direction between the base 21 and the first pull shaft 10, a first sealing ring 232 is disposed between the top pin 23 and the second pull shaft 22, and a second sealing ring 221 may be disposed between the base 21 and the second pull shaft 22, so that the sealing performance of the locking mechanism 1 is effectively improved.

Fig. 7 is a schematic structural view of the abutment 30. As shown in fig. 7, the driving device 2 includes a butt joint 30, and the butt joint 30 is used for butt-jointing the end of the second pull shaft 22 of the split locking mechanism 1, and the second pull shaft 22 drives the first pull shaft 10 to rotate so as to unlock or lock. Specifically, the abutment 30 includes a clamping portion 31 and a plug 32, and the abutment 30 is inserted into the clamping groove 223 through the clamping portion 31 to drive the second pull shaft 22 to rotate. The plug 32 extends in the axial direction and is located at the end of the abutment 30. When the driving device 2 abuts against the second pull shaft 22, the top head 32 of the driving device 2 pushes the top pin 23 to move to the concave area 231 corresponding to the first radial hole 224, and the locking piece 25 is disengaged from the base 21 by being retracted into the concave area 231.

When the unlocking operation is needed, the driving device 2 approaches the second pull shaft 22, the clamping part 31 is embedded into the clamping groove 223 at the bottom of the second pull shaft 22, and meanwhile, the top head 32 pushes the top pin 23 upwards to move so as to compress the elastic piece 24; after the knock pin 23 moves up, the concave area 231 of the knock pin 23 moves to the position of the first radial hole 224, the locking piece 25 loses the pushing force and can withdraw from the locking hole 213, and part of the locking piece moves to the position of the concave area 231, so that the unlocking operation of the second pull shaft 22 is realized.

Then, the butt joint 30 of the driving device 2 drives the second pull shaft 22 to rotate, and the second pull shaft 22 drives the first pull shaft 10 to rotate until the bayonet 11 is located at the unlocking position. During the rotation of the second pull shaft 22, the stopper 26 moves within the stopper groove 214, rotationally moving from one end of the stopper groove 214 to the other end until the stopper 25 rotates to a position corresponding to the unlocking hole 212. At this time, since the stopper 26 has moved to the end position of the stopper groove 214 and cannot continue to rotate, excessive rotation of the first pull shaft 10 and the second pull shaft 22 can be prevented.

Finally, the driving device 2 is separated from the second pull shaft 22, the elastic piece 24 pushes the ejector pin 23 to reset downwards, the concave area 231 of the ejector pin 23 is separated from the position corresponding to the first radial hole 224, and the locking piece 25 is pushed out to the position partially located in the unlocking hole 212 along the direction of the first radial hole 224, so that unlocking operation is completed. The locking operation is similar to the unlocking operation and will not be described here again.

The split locking mechanism 1 and the split locking mechanism are detachably connected with the first pull shaft 10 through the second pull shaft 22 of the transmission assembly 20, and the other end of the second pull shaft 22 can be abutted against the driving device 2 to drive the first pull shaft 10 to rotate, so that the unlocking and locking states of the locking mechanism 1 are switched. In this way, different transmission assemblies 20 can be installed according to the model of the driving device 2, and the lock body does not need to be replaced, so that the adaptability of the locking mechanism 1 can be improved, and the cost of the locking mechanism 1 can be reduced. In addition, the limiting piece 26 is located in the limiting groove 214 to rotate in the rotating process, and the rotating angle of the second pull shaft 22 is limited by the length of the limiting groove 214 in the circumferential direction, so that the second pull shaft 22 is prevented from excessively rotating in the unlocking or locking process and cannot enter the locking or unlocking state.

When the locking mechanism 1 needs to be assembled, referring to fig. 2 and 3, the locking member 25 and the limiting member 26 are respectively placed in the first radial hole 224 and the second radial hole 225, then the second pull shaft 22 is placed in the accommodating cavity 215 of the base 21 from above the base 21, the ejector pin 23 is placed in the axial hole 222 from above the second pull shaft 22, the elastic member 24 is placed above the ejector pin 23, and finally the first pull shaft 10 and the upper cover 211 are mounted on the base 21, so that the whole locking mechanism 1 is mounted.

Therefore, since the second pull shaft 22 and the first pull shaft 10 are of a split structure, the knock pin 23 is fitted into the second pull shaft 22 from above the second pull shaft 22, and thus, the lower end surface of the second pull shaft 22 is not provided with a recessed area for mounting the knock pin 23, and thus, freezing of moisture on the lower end surface of the second pull shaft 22, which results in failure of the unlocking or locking operation, can be avoided. Further, in the present embodiment, the locking groove 223 of the second pull shaft 22 may be provided on the side surface of the second pull shaft 22 instead of the end surface, and the locking portion 31 of the driving device 2 may be inserted into the locking groove 223 during the abutting process with the driving device 2, and even when the locking groove 223 is frozen, the locking portion 31 may scoop out the ice cubes in the locking groove 223 without causing the abutting failure due to the ice cubes.

In the several specific implementations provided in the present disclosure, it will be apparent to those skilled in the art that the present disclosure is not limited to the details of the above-described exemplary embodiments, and that the present disclosure may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Furthermore, it is evident that the word "comprising" does not exclude other elements or steps, and that the singular does not exclude a plurality. The terms first, second, etc. are used to denote a name, but not any particular order.
