[0047] A battery lock, such as Figures 2 to 7 As shown, it includes a lock head 30 and a lock body 10, the lock head 30 has a bearing surface 32, and the bearing surface 32 is provided with a lock head through hole 31, and the lock body 10 includes a base 11, a lock rod 40, a clamping portion 41, a stopper assembly, a rotating member 20 and a rotating member protection device. The clamping portion 41 is arranged at one end close to the lock rod 40, and the other end of the lock rod 40 is threadedly connected to the rotating member 20. A lock hole 21 is arranged at one end of the rotating member 20, and the clamping portion 41 can pass through the lock head through hole 31. The bearing surface 32 is provided with a groove 321 for clamping the clamping portion 41, and the groove 321 is staggered with the lock head through hole 31. The groove 321 of the clamping portion 41 and the bearing surface 32 is used to clamp the lock head 30 and the lock body 10. When the clamping portion 41 is in the clamping position, the lock head 30 and the lock body 10 are connected together through the clamping portion 41 and the bearing surface 32. When the clamping portion 41 is in the unlocking position, the lock head 30 and the lock body 10 can be separated from each other to achieve unlocking. Figure 7 30 is a schematic diagram of the structure of the lock. Figure 7As shown, as an example, the lock head 30 can be installed on the battery box, and the lock body 10 can be installed on the fixing part (such as the car body), but the present embodiment is not limited to this. The lock head 30 can also be connected to the fixing part, and the lock body 10 can be installed on the battery box. Those skilled in the art can set the installation positions of the lock head 30 and the lock body 10 as needed. The lock head 30 is generally a flat plate structure, but it can also be a structural member of other shapes to adapt to the battery box. The stopper assembly includes a connector 60 and a guide groove 61. The guide groove 61 is arranged on the side of the lock rod 40. The connector 60 is fixed to the base 11. A part of the connector 60 can slide in the guide groove 61. The guide groove 61 includes at least one curved section of the guide groove 61. The curved section of the guide groove 61 is spirally extended around the circumferential direction and the length direction of the lock rod 40 to form a spiral groove around the lock rod 40. The stopper assembly is used to control the rotation angle of the lock rod 40, so as to realize the control of the clamping part 41 from the clamping position to the unlocking position or from the unlocking position to the clamping position. Specifically, when the lock head 30 needs to be locked with the lock body 10, the lock rod 40 with one end of the clamping part 41 passes through the lock head through hole 31, at which time the plug-in component 60 is located at the bottom of the guide groove 61 of the curved segment, the clamping part 41 and the lock rod 40 are located in the unlocking position, and the rotating member 20 is rotated, and the rotating member 20 drives the lock rod 40 to rotate a certain angle and move a certain distance in the axial direction, driving the clamping part 41 to rotate a certain angle and approach the groove 321 of the lock head 30, and reaching the locked position to complete the locking connection between the lock head 30 and the lock body 10.

[0048] like Figure 3 , Figure 4As shown, the rotating member protection device includes a moving member 13, a locking member 12 and an elastic member 14. The locking member 12 is fixed to the base 11 by a screw 111. The moving member 13 is used to accommodate the rotating member 20. When the moving member 13 accommodates the rotating member 20, the moving member 13 is engaged with the rotating member 20 and the locking member 12 along the rotation direction of the rotating member 20 to lock the rotating member 20. When the moving member 13 is disengaged from the engagement of the locking member 12, the rotating member 20 extends from the moving member 13, and the moving member 13 can rotate together with the rotating member 20. The moving member 13 has a first through hole 132 that penetrates along the axial direction of the rotating member 20, and the moving member 13 is accommodated in the first through hole 132, and the locking member 12 includes a second through hole 122 that penetrates along the axial direction of the rotating member 20, and the moving member 13 is accommodated in the second through hole 122. The inner wall of the first through hole 132 of the moving member 13 and the outer wall of the rotating member 20 are engaged through latch teeth and a latch groove, a truncated cone-shaped countersunk hole is provided at one end of the second through hole 122 of the locking member 12, a latch joint matching the shape of the countersunk hole is provided at one end of the moving member 13, and a plurality of continuous latch teeth are provided on the contact surface of the countersunk hole and the latch joint, which are respectively the locking member latch teeth 121 and the moving member latch teeth 131, and the locking member 12 and the moving member 13 are engaged and engaged through the locking member latch teeth 121 and the moving member latch teeth 131. The battery lock is engaged with the locking member 12 through the moving member 13, and the rotating member 20 is accommodated in the moving member 13, so that the outside world cannot contact the rotating member 20 and drive the rotating member 20 to rotate, and at the same time, the rotating member 20 is also engaged with the locking member 12 through the moving member 13 and will not loosen. When it is necessary to drive the rotating member 20 to rotate, the moving member 13 is pushed to disengage from the locking member 12, and the rotating member 20 is extended from the moving member 13 to facilitate driving the rotating member 20 to rotate, thereby preventing misoperation of the rotating member 20 and preventing the rotating member 20 from rotating uncontrollably. The inner wall of the first through hole 132 of the movable member 13 and the outer wall of the rotating member 20 are clamped together by means of latch teeth and a latch groove, and the countersunk hole and the contact surface of the clamping joint are respectively provided with a plurality of continuous latch teeth, and the locking member 12 and the movable member 13 are engaged and clamped together by means of the locking member latch teeth 121 and the movable member latch teeth 131. Compared with the prior art, in this clamping mode, when the movable member 13 and the locking member 12 just come into contact, the locking member 12 and the movable member 13 only need to be slightly rotated to make the locking member latch teeth 121 engage with the movable member latch teeth 131, which is more convenient for clamping into place, and a truncated cone-shaped countersunk hole is provided at one end of the second through hole 122 of the locking member 12, and a clamping joint matching the shape of the countersunk hole is provided at one end of the movable member 13, which further facilitates the movable member 13 and the locking member 12 to be clamped into place and the clamping position is accurate.

[0049] like Figure 4 As shown, the elastic member 14 is abutted between the moving member 13 and the rotating member 20. The elastic member 14 is used for the moving member 13 to be reset under the elastic force of the elastic member 14 when the external force abutting against the moving member 13 disappears.

[0050] like Figure 5 As shown, it also includes a first guide section and a second guide section, both of which are linear guide sections along the axial direction of the locking rod 40, and the first guide section, the curved section and the second guide section are connected in sequence. Figure 3 , Figure 4 , Figure 5 As shown, in this embodiment, the guide groove 61 is provided on the side wall of the lock rod 40, and includes three parts: a first guide section, a curved section, and a second guide section. The first guide section and the second guide section are respectively located at the two ends of the curved section and are connected to the curved section, so that the connector 60 can move between the first guide section and the curved section, or between the curved section and the second guide section. Figure 5 As shown, the first guide section is an AB section slot body, extending along the length direction of the lock rod 40 and located above the curved section. The curved section is a BC section slot body, the top of which is connected to the bottom of the first guide section, and spirally extends around the circumferential direction and length direction of the lock rod 40 to form a spiral groove around the lock rod 40. The angle of the curved section extending along the circumferential direction is set according to the rotation angle of the lock rod 40. When the plug-in 60 is located at one end of the curved section close to the first guide section, the lock rod 40 starts to rotate and drives the clamping part 41 to rotate from the unlocking position to the locking position; when the plug-in 60 is located at one end of the curved section close to the second guide section, the lock rod 40 rotates and drives the clamping part 41 to rotate to the locking position. The second guide section is a CD section slot body, extending along the length direction of the lock rod 40 and located below the curved section. The top of the second guide section is connected to the bottom of the curved section, so that the plug-in 60 can move back and forth between the curved section and the second guide section.

[0051] like Figures 8 to 12 As shown, an unlocking mechanism includes a top member 50. When unlocking, one end of the top member 50 abuts against the moving member 13 to lift the moving member 13 and separate it from the locking member 12. The middle of the top member 50 is provided with a receiving cavity for receiving the rotary head assembly. Fig.10 , Fig.11As shown, the swivel assembly includes a swivel 70, a transmission shaft 72, a first hinge shaft 71, and a second hinge shaft 7.

The shape of the swivel 70 is adapted to the lock hole 21, and the relative positions of the swivel 70 and the lock hole 21 remain unchanged after they are matched. A plurality of teeth are respectively provided on the outer side of the swivel 70 and the inner side of the lock hole 21, and the teeth of the swivel 70 mesh with the teeth of the lock hole 21. The unlocking mechanism is used in conjunction with the above-mentioned battery lock. When unlocking, one end of the top member 50 abuts against the moving member 13, and the moving member 13 is lifted up and disengaged from the locking member 12. The middle part of the top member 50 is provided with a receiving cavity for accommodating the swivel assembly. The swivel head 70 is hinged to one end of the transmission shaft 72 through the first hinge shaft 71, and the transmission shaft 72 is hinged to the inner wall of the top member 50 through the second hinge shaft 7. The swivel head assembly includes two hinge shafts, which allow the swivel head assembly to have a certain degree of curvature. When the swivel head 70 is inserted into the lock hole 21 of the rotating member 20, the two hinge shafts can automatically adjust the direction of the swivel head 70, making it easier to insert into the lock hole 21 and mesh with the teeth of the lock hole 21. The driving device drives the top member 50 to rotate.

[0052] like Fig.11 As shown, a first buffer spring 81 is provided on the outer side of the top member 50, and a first clamping shoulder is provided on the outer side of the top member 50. One end of the first buffer spring 81 abuts against the first clamping shoulder on the outer side of the top member 50, and the other end of the first buffer spring 81 abuts against the flange 90.

Fig.11 As shown, a second buffer spring 74 is provided on the outer side of the transmission shaft 72, a second clamping shoulder is provided on the inner side of the top piece 50, a support ring 75 is provided between the rotary head 70 and the top piece 50, one end of the second buffer spring 74 abuts against the second clamping shoulder, and the other end of the second buffer spring 74 abuts against the support ring 75. The second buffer spring 74 is used to buffer the pressure generated by the collision or friction between the rotary head 70 and the lock hole 21 when the rotary head 70 is inserted into the lock hole 21, to prevent hard contact, reduce the wear of parts and components, and extend the service life.

[0053] like Fig.10 As shown, the first hinge axis 71 and the second hinge axis 7 are perpendicular to each other, so that the rotary head 70 can be slightly movable in four directions, namely, along the axial direction of the first hinge axis 71 and the axial direction of the second hinge axis 7 .

[0054] like Figure 8 As shown, the driving device includes a motor 91 and a flange 90. The other end of the top member 50 is detachably connected to the flange 90, and the motor 91 drives the top member 50 to rotate through the flange 90. The other end of the top member 50 can be hinged to the flange 90, and the flange 90 drives the top member 50 to rotate through the hinge shaft. A sheath 80 is provided outside the top member 50 and the first buffer spring 81, and one end of the sheath 80 is fixed to the flange 90.

[0055] like Figure 12 to Figure 14 As shown, when the lock head 30 and the lock body 10 need to be locked, the lock rod 40 with one end of the clamping portion 41 passes through the lock head through hole 31, and the plug-in component 60 is located as shown in FIG. Figure 5 At the bottom of the second guide section of the guide groove 61, that is, point D of the CD section groove body, the clamping portion 41 and the locking rod 40 are located in the unlocking position, as shown in FIG. Fig.12 As shown, the unlocking mechanism moves upward from the lower part to the lower part of the lock body 10, at which time the moving member 13 and the locking member 12 are engaged with each other through teeth, and the rotating member 20 is received in the moving member 13. Fig.13 As shown, the unlocking mechanism has just contacted the lower part of the lock body 10, the top member 50 has just contacted the moving member 13, and has not yet lifted the moving member 13, the moving member 13 and the locking member 12 are still connected together, and the rotating head 70 has not yet extended into the lock hole 21. Fig.14 As shown, the unlocking mechanism continues to move upward, the top member 50 lifts the moving member 13, the moving member 13 is separated from the locking member 12, the rotating member 20 is exposed from the moving member 13, the swivel 70 extends into the lock hole 21 of the rotating member 20, and the teeth on the swivel 70 mesh with the teeth in the lock hole 21 so that the swivel 70 and the lock hole 21 are clamped together and fixed. The motor 91 drives the top member 50 to rotate through the flange 90, the top member 50 drives the transmission shaft 72 to rotate through the second hinge shaft 7, the transmission shaft 72 drives the swivel 70 to rotate through the first hinge shaft 71, and the swivel 70 drives the rotating member 20 to rotate through the meshed teeth. At this time, the plug-in member 60 moves from point D of the second guide section to point C, the rotating member 20 drives the lock rod 40 to move along the lock rod axial direction, and the clamping portion 41 approaches the receiving surface of the lock head 30.

When the plug-in component 60 reaches point B, the locking rod 40 stops rotating, and the locking rod 40 continues to move axially, and the clamping part 41 continues to approach the bearing surface 32 of the lock head 30. Finally, when the plug-in component 60 reaches point A, the clamping part 41 enters the groove 321 of the bearing surface 32 and abuts against the groove 321 of the bearing surface 32, so that the lock head 30 and the lock body 10 are locked. At this time, the unlocking mechanism is removed, and the moving component 13 is reset under the action of the elastic component 14. The moving component 13 covers the rotating component 20, and the teeth of the moving component 13 mesh with the teeth of the locking component 12 to clamp the rotating component 20 so that it cannot rotate at will. When unlocking is required, the action of the unlocking mechanism is the same as above, except that the rotation direction of the rotating head 70 of the unlocking mechanism is opposite to that of the above. The action of the battery lock is basically the same as above, except that the rotating member 20 and the locking rod 40 rotate in opposite directions, and the connector 60 moves from point A to point D.
