Example 1

In an electric truck, for example, a battery box is placed on a vehicle body of the electric truck, and the battery box needs to be locked to the vehicle body using a battery lock in order to prevent the battery box from moving on the vehicle body. The existing battery lock is generally screwed into a nut through a screw to lock a battery box, and the situation that the position of a thread head is not accurately butted when the threads are butted and screwed due to the possible deviation of the battery box at the placing position of a vehicle body causes the threads to be abraded in the thread screwing process, even the clamping stagnation situation occurs, the threads cannot be screwed normally, and the locking failure is caused.

The rotation member 36 has a substantially cylindrical structure, and has a threaded hole extending in a longitudinal direction in an inner portion of one end thereof, and the other end thereof rotatably connected to the base 34 through the receiving chamber 341 of the base 34. Specifically, a plurality of bearings arranged along the circumferential direction are arranged between the rotating surface of the rotating member 36 and the inner wall of the cavity 341 of the base 34, so that the rotating member 36 can rotate in the through hole of the base 34, and the rotating member 36 is clamped on the side wall of the cavity 341, so that the rotating member 36 drives the connecting member 32 to move along the length direction when rotating relative to the connecting member 32. The driving machine 35 is connected to the base 34 for driving the rotation member 36 and the connecting member 32 to rotate. In other embodiments, the drive assembly may have other configurations, such as a linear motor or other drive mechanism, to drive the link 32 in a longitudinal direction.

The connecting member 32 is rod-shaped, and has an external thread at the bottom thereof, and the rotating member 36 and the connecting member 32 are screwed together by engaging the internal thread and the external thread, and have a top portion extending from the receiving chamber 341.

Referring again to fig. 5, the bottom of the rotating member 36 is connected to the driving machine 35, so that the driving machine 35 can drive the rotating member 36 to rotate. The rotatable member 36 is coupled to the coupling member 32 and can rotate the coupling member 32 or rotate relative to the coupling member 32 to draw the lock cylinder 20 and the lock body 30 to move relative to each other via the coupling member 32. In this embodiment, the driving machine 35 comprises a motor and a gearbox, which are mounted at the bottom of the base 34, and an output shaft extending towards the base 34 is connected to a traction member 351. As shown in fig. 5, the bottom of the traction member 351 is connected to the output shaft of the driving machine 35, and the other end of the traction member 351 is connected to the bottom of the rotating member 36, so that the driving machine 35 can drive the rotating member 36 to rotate through the traction member 351. In other embodiments, the rotating element 36 may also be directly fixedly connected to the driving machine 35, which is not limited in this application.

Referring again to FIGS. 2-5, the shackle assembly is adapted to shackle the lock cylinder 20 and the lock body 30 such that when the lock cylinder 20 and the lock body 30 are moved toward each other to a predetermined position, the shackle assembly is engaged with each other such that the lock cylinder 20 and the lock body 30 are coupled by the shackle assembly without disengagement. The joint subassembly includes first joint spare 31 and second joint spare, one in first joint spare 31 and the second joint spare connect in tapered end 20, the other one connect in the connecting piece 32 of lock body 30, first joint spare 31 and second joint spare joint are in order to connect tapered end 20 and lock body 30. As an example, in the present embodiment, the first snap 31 is provided to the lock head 20.

In the present embodiment, as shown in fig. 2 and 3, the first clip 31 includes a bearing portion and an entry passage 21. The inlet channel 21 of the first engaging member 31 is a strip-shaped through hole penetrating through the lock head 20, and the bearing portion includes a bearing surface 22. The bearing surface 22 is the side of the lock cylinder 20 away from the lock body 30. The bearing portion is provided with a groove 221 corresponding to the clamping portion 312, and the clamping portion 312 abuts against the bearing surface 22 of the bearing portion in the groove 221. In other embodiments, the inlet channel 21 may also be a special-shaped hole with other shapes, such as a cross-shaped or a quincuncial through hole, so that the second engaging member can be engaged with the bearing surface 22 by rotating a predetermined angle after passing through the inlet channel 21 to achieve an engaging connection. Correspondingly, the second clamping piece comprises a plurality of clamping parts 312, and the clamping parts 312 form one of a straight line shape, a plum blossom shape, a cross shape or a meter shape along the projection of the length direction of the connecting piece 32.

As shown in fig. 1 and 4, the second snap-in member includes a lock lever 311 and a snap-in portion 312. In the present embodiment, the lock lever 311 is coaxially connected to the end of the connector 32, and is provided integrally with the connector 32. However, a person skilled in the art may set the locking lever 311 in other shapes, and the locking lever 311 may also be set separately, so that the connecting element 32 or the rotating element 36 may drive the locking lever 311 to rotate when rotating, thereby completing the snapping operation. The clamping portion 312 is connected to the locking bar 311, and extends along the radial direction of the locking bar 311 for hooking to the bearing portion. In this embodiment, there may be two snap-in portions 312, which extend along the radial direction of the lock bar 311 and form a T-shaped structure with the lock bar 311, but in other embodiments, the snap-in portions 312 may have other shapes, such as a cross or a quincunx structure. According to the relative position between the clamping portion 312 and the access passage 21, the clamping portion 312 has a clamping position and an unlocking position in the rotation process, the clamping position refers to a position where the clamping portion 312 rotates to overlap with at least a part of the bearing surface 22 of the bearing portion along the length of the lock bar 311, and preferably a position where the clamping portion 312 is perpendicular to the width direction of the access passage 21. The unlocking position is that the clamping portion 312 rotates to a position corresponding to the entrance channel 21, so that the clamping portion 312 can move along the entrance channel 21 until the lock head 20 is separated from the lock body 30, or alternatively, the clamping portion 312 can move along the entrance channel 21 to a position over the bearing surface 22 so that the clamping portion 312 rotates to the clamping position.

Fig. 6 is a partially enlarged view of a circled portion of fig. 5, and fig. 7 is a structural schematic view of a connecting member and a first snap member. As shown in fig. 6 and 7, the stop assembly serves to stop the link 32 to control the rotational position of the link 32. The stopping component comprises a plug piece 331 and a guide groove 33, one of the plug piece 331 and the guide groove 33 is connected to the connecting piece 32, and the other is arranged on the inner wall of the cavity 341 of the base 34. In the present embodiment, the guide groove 33 is provided in the connector 32, and the plug 331 is provided on the inner wall of the housing 341 of the base 34.

As shown in fig. 6, the inner wall of the receiving chamber 341 of the base 34 is provided with a mounting hole 342 extending in a radial direction of the connector 32, and the plug 331 includes one or more balls, which are mounted in the mounting hole 342 and a portion of which protrudes from an end of the mounting hole 342 and is inserted into the guide groove 33. The plug 331 is fitted into the guide groove 33 and controls the rotation of the link 32 (i.e., the position of the link 32 in the circumferential direction) according to the shape of the guide groove 33 during the up and down movement of the link 32 in the longitudinal direction, and also functions to prevent the rotation of the link 32, i.e., functions to lock the link 32 in the rotational direction of the link 32 so that the rotary piece 36 can rotate relative to the link 32. In other embodiments, the plug may also include a pin or a boss inserted into the guide slot, which is not limited in this application.

Fig. 8 is a structural view of the guide groove 33 in the expanded state. As shown in fig. 8, in the present embodiment, the guide groove 33 is provided in the side wall of the connecting member 32, and includes three portions: a first guide section, a curved section, and a second guide section. The first and second guide sections are located at both ends of the curved section, respectively, and communicate with the curved section, so that the plug 331 can move between the first and curved sections, and also between the curved section and the second guide section. As shown in fig. 8, the first guide section is an a-B section groove body, extends along the length direction of the connecting piece and is positioned above the curved section. The curved section is a B-C section groove body, the top end of which is communicated with the bottom end of the first guide section and extends spirally around the circumferential direction and the length direction of the connecting piece 32 to form a spiral groove around the connecting piece 32. The angle of extension of the curved section in the circumferential direction is set according to the rotation angle of the connecting piece 32, and when the plug-in unit 331 is located at one end of the curved section, the connecting piece 32 rotates to drive the clamping assembly to rotate until the first clamping piece and the second clamping piece are located at clamping positions (that is, the clamping portion rotates to a position at least partially overlapped with the bearing surface 22 of the bearing portion along the length); when the plug 331 is located at the other end of the curved section, the connecting member 32 rotates until the first and second catching members are in the unlocking position (i.e., the catching portion 312 corresponds to the position of the entry passage 21 so that the catching portion 312 can be disengaged from the entry passage 21 or moved along the entry passage 21). The second guide section is a C-D groove extending along the length direction of the connecting member 32 and located below the curved section, and the top end of the second guide section is communicated with the bottom end of the curved section, so that the plug 331 can move back and forth between the curved section and the second guide section.

The locking method using the battery lock is described in detail below.

First, the lock head 20 is mounted to the battery case 10, and the lock body 30 is mounted to the fixing member 11. In the initial state, the battery lock is in the unlocked position, at which time the plug 331 is inserted into the second guide section of the guide slot 33, corresponding to the position of the plug 331, and the engaging portion 312 corresponds to the position of the entry passage 21 (i.e., the unlocked position).

In the process that the battery box 10 and the fixing member 11 are close to each other, the locking rod 311 of the clamping assembly moves along the entering channel 21 until the clamping portion 312 crosses the bearing surface 22 of the bearing portion (i.e., extends out from the locking head 20), the end surface (i.e., the bearing surface 22) of the bearing portion, which is far away from the rotating member 36, is located below the clamping portion 312, and at this time, the clamping portion 312 is located obliquely above the bearing surface 22 of the bearing portion.

Then, the driving unit 35 of the driving unit is started, the traction member 351 of the driving unit 35 drives the rotation member 36 to rotate, and since one end of the connector 311 is located in the mounting hole 342 and the other end is inserted into the second guide section (i.e., the C-D section groove body) of the guide groove 33, the connecting member 32 is locked by the connector 311 in the circumferential direction and cannot rotate, and can only move in the length direction of the connecting member 32. Thus, the rotating member 36 can rotate relative to the connecting member 32, the connecting member 32 drives the engaging portion 312 to move in a direction close to the bearing surface 22, and meanwhile, the rotating member 36 is limited in the cavity 341 of the base 34 and cannot move in the length direction. When the plug 331 is located at the top end of the second guiding section of the guiding slot 33, the engaging portion 312 moves a distance along the direction close to the carrying surface 22, so as to adjust the distance between the engaging portion 312 and the carrying surface 22, and prevent the engaging portion 312 from being too high or too low and being blocked by other components, which affects the rotation of the engaging portion 312. Meanwhile, the connecting piece 32 can be prevented from rotating in the moving process, and the clamping portion 312 is prevented from deviating from the unlocking position in the moving process to cause locking failure.

When the connecting element 32 moves to the plug-in unit 331 along the length direction and enters the curved section (BC section slot) from the second guiding section (CD section) of the guiding slot 33, on one hand, the rotating element 36 can drive the connecting element 32 to rotate due to the fact that the rotating element 36 is in threaded connection with the connecting element 32, and a certain friction exists between the rotating element 36 and the connecting element 32, so that the locking rod 311 can be driven to rotate. On the other hand, since the rotating member 36 and the connecting member 32 drive the connecting member 32 to move in the longitudinal direction during the relative rotation, the plug member 331 can move relative to the guide slot 33 during the longitudinal movement of the connecting member 32, i.e., forcibly guide the connecting member 32 to rotate along the curved section of the guide slot 33, and the rotation angle of the connecting member 32 can be controlled according to the position of the plug member 331 on the curved section of the guide slot 33. When the plug 331 moves to the top end of the curved section, the connecting member 32 rotates to a position where at least a part of the clamping portion 312 overlaps with the carrying surface 22 of the carrying portion along the length direction of the lock rod 311, that is, the clamping component is located at the clamping position. In the present embodiment, the engagement position may be a position where the engagement portion 312 is at 90 degrees to the entry passage 21 (i.e., a position perpendicular to the width direction of the entry passage 21).

Then, the rotating member 36 continues to rotate, and drives the connecting member 32 to move in the length direction until the plug 331 enters the first guide section of the guide slot 33. Since the first guide section extends in the longitudinal direction of the link 32, the link 32 can be locked in the rotational direction of the link 32, resulting in that the link 32 cannot rotate but can move only in the longitudinal direction. Thus, the rotating member 36 can rotate relative to the connecting member 32, so as to drive the connecting member 32 to move along the length direction until the engaging portion 312 abuts against the groove 221 of the bearing surface 22. Meanwhile, the connecting piece 32 can be prevented from rotating in the moving process, and the clamping portion 312 is prevented from deviating from the clamping position in the moving process to cause locking failure.

Finally, the rotating member 36 continues to rotate to drive the connecting member 32 to continue to move along the length direction until the plug 331 moves to the top end position of the first guiding section, and at this time, the connecting member 32 has a preset pre-tightening force by pulling the locking head 20 through the engaging portion 312, so as to achieve the purpose of locking the locking head 20 to the fixing member 11. Furthermore, by controlling the length of the first guiding section, the locking force of the lock head 20 and the lock body 30 in the locked state can be controlled.

When the battery box 10 needs to be unlocked, the driving machine 35 drives the rotating member 36 to rotate in the opposite direction, and at this time, because the inserting member 331 is inserted into the first guiding section of the guiding slot 33, the connecting member 32 is locked along the rotating direction of the connecting member 32, so that the connecting member 32 cannot rotate and can only move along the length direction of the connecting member 32, and thus, the rotating member 36 can rotate relative to the locking rod 311, and the connecting member 32 can move along the direction away from the locking head 20, so that the pre-tightening force of the battery box 10 can be released.

When the plug 331 is located at the bottom end position of the first guiding segment of the guiding slot 33, the engaging portion 312 is already located above the carrying surface 22 and separated from the carrying surface 22 and has a predetermined distance from the carrying surface 22. At this time, the clamping portion 312 is far away from the bearing surface 22 and at a proper height position, so as to prevent the clamping portion 312 from being clamped in the subsequent process of rotating the clamping portion 312.

When the plug 331 moves along the first guiding section of the guiding slot 33 to the curved section, on one hand, since the rotating member 36 is in threaded connection with the connecting member 32, so that there is a certain friction between the rotating member 36 and the connecting member 32, the rotating member 36 can drive the connecting member 32 to rotate, and thus the locking lever 311 can be driven to rotate. On the other hand, since the rotation member 36 and the connection member 32 drive the connection member 32 to move in the longitudinal direction during the relative rotation, the plug member 331 can move along the curved section of the guide slot 33 to forcibly guide the connection member 32 to rotate during the movement of the connection member 32 in the longitudinal direction, and the rotation angle of the connection member 32 can be controlled according to the position of the plug member 331 on the curved section of the guide slot 33. When the plug 331 moves to the bottom end of the curved section, the connecting member 32 rotates until the catching portion 312 is located at a position corresponding to the entry passage 21, so that the catching portion 312 can be disengaged from the entry passage 21 (i.e., an unlocked position). At this time, the catching portion 312 is located at a position corresponding to the entry passage 21.

Then, the rotating member 36 continues to rotate, which drives the connecting member 32 to move along the length direction until the plug 331 enters the second guiding section of the guiding slot 33 from the curved section, and since the second guiding section extends along the length direction, the plug 331 locks the connecting member 32 along the rotation direction of the connecting member 32, which results in that the connecting member 32 cannot rotate, so that the rotating member 36 can rotate relative to the connecting member 32, thereby driving the connecting member 32 to move along the length direction.

Finally, the rotating member 36 continues to rotate to drive the connecting member 32 to continue to move along the length direction of the connecting member 32 until the plug 331 moves to the bottom position of the second guiding section, at this time, the clamping portion 312 is located in the access channel 21 or is separated from the lock 20 through the access channel 21, and the distance between the clamping portion and the bearing surface when the clamping portion is at the unlocking position can be adjusted according to the length of the second guiding section (i.e., different positions are provided according to the length of the second guiding section). In this way, it is further ensured that the position of the snap-in portion 312 already corresponds to the access passage 21, preventing damage to the battery lock when the lock head 20 and the lock body 30 are disengaged.

Finally, the battery box 10 can be moved, and the lock body 30 is separated from the lock head 20, thereby completing the unlocking process.

Example 2

Fig. 9 is a schematic structural view of the battery lock in embodiment 2, and fig. 10 is a schematic sectional structural view of the battery lock in embodiment 2. As shown in fig. 9 and 10, the embodiment 2 is different from the embodiment 1 in that the positions of the first and second locking members of the locking assembly are reversed, and in the embodiment 2, the access passage 21 and the bearing portion of the first locking member are connected to the connecting member 32 of the lock body 30. The structure of the first clamping piece is the same as that of embodiment 1, and is not described again here. Correspondingly, a second latch member (i.e., the T-bar configuration shown in FIG. 9) of the latch assembly is connected to the locking head 20. The structure of the second clamping member is the same as that of embodiment 1, and is not described herein again.

Further, embodiment 2 is different from embodiment 1 in that the positions of the plug 331 and the guide groove 33 are reversed, and specifically, the plug 331 may be a plug extending in the radial direction of the connecting member 32. The guide groove 33 is disposed on a sidewall of the receiving cavity 341 of the base 34, and one end of the plug 331 is connected to the connector 32, and the other end is inserted into the guide groove 33. The structure of the guide groove 33 is the same as that of embodiment 1, and is not described here again. It is noted that, due to the adjustment of the relative position, the guiding groove 33 is different from the embodiment 1 in that, in the embodiment 1, the first guiding section is located above the curved section, and the second guiding section is located below the curved section. In the present embodiment, the first guiding section is located below the curved section, and the second guiding section is located above the curved section. However, a person skilled in the art may also provide other types of arrangements for the guide slot 38, for example, different connectors 331 are used for three sections of the guide slot 33, so that the corresponding curved section, the first guide section and the second guide section of the guide slot 33 may be configured according to the position of the connector 331, which is not limited in the present application.

In some preferred embodiments, the end of the plug 331 may also be provided with a rotating ball or roller, so that the friction of the plug 331 may be reduced.

Foretell battery lock before the lock connects battery box 10, connecting piece 32 passes through threaded connection with rotating piece 36 rotate piece 36 and drive connecting piece 32 rotates extremely behind the first joint spare 31 joint of joint subassembly in the second joint spare, rotate 36 relative connecting piece 32 rotations, thereby make connecting piece 32 pulls tapered end 20, will battery box 10 lock in the automobile body. The screwing-in or screwing-out action in the thread matching process is not needed in the process of locking the battery box 10, the problem that threads are abraded due to inaccurate butt joint of thread heads when the threads are in butt joint and screwed is avoided, the battery lock is in butt joint in a clamping mode, large butt joint errors can be allowed, the structure is simple, and the production and maintenance cost is low.

In addition, in the battery lock, the guide groove 33 and the plug piece 331 are arranged on the stop component, and the plug piece 331 is inserted into the curved section of the guide groove 33, so that during the rotation of the rotating piece 36 relative to the connecting piece 32, on one hand, the rotating piece 36 can drive the connecting piece 32 to rotate through friction force, and on the other hand, when the connecting piece 32 is pulled to move along the length direction, the plug piece 331 moves along the curved section of the spiral groove 33 to guide the connecting piece 32 to rotate, thereby preventing the problem that the connecting piece 32 cannot rotate due to the clamping of external force. Further, the battery lock can control the rotation range of the connecting member 32 by setting the spiral angle of the curved section, and control the rotation angle of the connecting member 32 by the position of the insertion member 331 on the curved section, so that the rotation control of the connecting member 32 is more accurate.
