[0036] Referring to Figures 1 to 4 As shown, this embodiment provides a limiting structure for fast battery replacement. It is arranged on the frame 3. The frame 3 includes a supporting end face for supporting the battery 4. Specifically, the limiting structure for fast battery replacement includes a fixing member 1 and a movable member 2, where

[0037] The fixing member 1 is fixed to the frame 3 and jointly forms a slot 11 (not shown) with the frame 3. The movable member 2 includes a main body 21, a limiting portion, and a plug connector 23. The main body 21 is hinged to the frame 3, and the plug connector 23 is telescopically disposed in the main body 21 along a first direction. The limiting portion is disposed on both sides of the plug connector 23 along a second direction. The limiting portion includes a first limiting sub-portion 221 and a second limiting sub-portion 222, and the first limiting sub-portion 221 and the second limiting sub-portion 222 are used to respectively abut against two adjacent end faces of the battery 4. The main body 21 can rotate relative to the frame 3 to move the limiting portion below the supporting end face of the frame 3, or to align the plug connector 23 with the slot 11 so that the plug connector 23 is inserted into the slot 11. The first direction is perpendicular to the second direction.

[0038] In the drawings, the a direction is set as the first direction, and the b direction is set as the second direction. When the battery 4 is fixed to the frame 3, the first direction and the second direction are respectively the length direction and the width direction of the battery 4. The first direction is the direction for taking out or putting in the battery 4 from the frame 3 in this embodiment.

[0039] Specifically, when the main body 21 rotates to align the plug connector 23 with the slot 11, the first limiting sub-portion 221 extends along the first direction and can abut against the end face of the battery 4 in the second direction, and the second limiting sub-portion 222 extends along the second direction and can abut against the end face of the battery 4 in the first direction. The two end faces of the battery 4 abutting against the limiting portion are two adjacent end faces of the battery 4. In this embodiment, the first limiting sub-portion 221 and the second limiting sub-portion 222 are used to respectively abut against two adjacent end faces of the battery 4, and thus can realize the abutting and limiting of the battery 4 in two directions, effectively ensuring the reliability and effectiveness of the battery 4 limiting. And the limiting portion is disposed on both sides of the plug connector 23, and the limiting portions on both sides can correspondingly limit two batteries 4, increasing the number of batteries 4 limited.

[0040] In addition, the main body 21 is hinged to the frame 3, and the main body 21 can rotate relative to the frame 3 and has an unlocking state and a locking state. When in the unlocking state, the main body 21 rotates relative to the frame 3 so that the limiting portion can be located below the supporting end face of the frame 3, avoiding interference with the taking and placing of the battery 4, enabling the battery 4 to be smoothly taken off from the supporting end face of the frame 3, or smoothly put into the frame 3 and supported on the supporting end face. When in the locking state, the main body 21 rotates relative to the frame 3 to align the plug connector 23 with the slot 11, and the plug connector 23 is inserted into the slot 11 to lock and fix the movable member 2, ensuring the fixation of the limiting portion, and thus reliably limiting the battery 4. This structure can realize the switching between the locking and unlocking states without disassembly and assembly, without using external connecting parts such as screws and bolts and tools such as screwdrivers, wrenches, and spanners, with simple operation, reducing manpower consumption, and strong practicability.

[0041] In this embodiment, the main body 21 has a telescopic groove extending in the first direction, and the insertion joint 23 slides telescopically in the telescopic groove. Specifically, the setting of the telescopic groove can be slidably matched with the insertion joint 23 to ensure that the insertion joint 23 slides strictly along the first direction.

[0042] Specifically, the main body 21 includes a first base 211 and a second base 212. The limiting part is fixed on the first base 211. The second base 212 is detachably arranged on the first base 211 and jointly forms a telescopic groove with the first base 211. Specifically, the first base 211 and the second base 212 can be connected by connecting pieces such as screws. Setting the main body 21 as the split first base 211 and second base 212 is convenient for opening the telescopic groove during maintenance, facilitating the taking and placing of the insertion joint 23, with a flexible structure and convenient operation.

[0043] Specifically, the second base 212 is provided with a long hole 2121 extending in the first direction. The long hole 2121 communicates with the telescopic groove. A driving head 231 is fixed on the insertion joint 23, and the driving head 231 passes through the long hole 2121 and extends outside the second base 212. The setting of the driving head 231 facilitates the operator to pull the insertion joint 23 to slide by hand. The driving head 231 passes through the long hole 2121. The setting of the long hole 2121 can guide the movement of the driving head 231, and on the other hand, can also play a role in sliding limit for the insertion joint 23.

[0044] Specifically, an elastic member is arranged in the telescopic groove. The elastic member is adapted to provide a force for forcing the insertion joint 23 to extend outside the telescopic groove. By setting the elastic member, the elastic force of the elastic member itself can always drive the insertion joint 23 to extend outward, so that when the main body 21 is in the locked state, the insertion joint 23 can be reliably inserted into the slot 11, effectively maintaining the locked and fixed state.

[0045] In addition, placing the elastic member in the telescopic groove can also provide reliable protection for the elastic member.

[0046] Optionally, the elastic member is set as a spring.

[0047] Specifically, the first base 211 is provided with a first mounting hole (not shown), and the second base 212 is provided with a second mounting hole 2122. The first mounting hole and the second mounting hole 2122 are fixedly connected by a connecting piece.

[0048] Optionally, the connecting piece is set as a screw, the first mounting hole is set as a threaded hole, and the screw passes through the second mounting hole 2122 and is threadedly connected to the first mounting hole.

[0049] Optionally, the connecting piece is set as a bolt and a nut. The bolt passes through the second mounting hole 2122 and is threadedly connected to the first mounting hole and the nut.

[0050] In this embodiment, a hinge shaft 12 is fixedly provided on the frame 3, and a hinge hole 2111 is correspondingly formed in the main body 21. The main body 21 is sleeved on the hinge shaft 12 through the hinge hole 2111 and is hinged to the hinge shaft 12. Specifically, the mating relationship between the hinge shaft 12 and the hinge hole 2111 is set as a clearance fit or an interference fit.

[0051] In this embodiment, a limiting head 13 is fixedly provided on the frame 3. The limiting head 13 includes a first abutting end face 131 and a second abutting end face 132. The first abutting end face 131 is adapted to abut against the limiting portion when the main body 21 rotates outward relative to the frame 3 to the limit position; the second abutting end face 132 is adapted to abut against the limiting portion when the main body 21 rotates inward relative to the frame 3 to the limit position. Specifically, the setting of the limiting head 13 can limit the rotation range of the main body 21. Specifically, referring to Figure 3 As shown, when the main body 21 rotates to the unlocked state and moves to the limit position, the second limiting portion 222 abuts against the first abutting end face 131, restricting the main body 21 from continuing to rotate outward relative to the frame 3; referring to Figure 4 As shown, when the main body 21 rotates to the locked state and moves to the limit position, the second limiting portion 222 abuts against the second abutting end face 132, restricting the main body 21 from continuing to rotate inward relative to the frame 3.

[0052] In this embodiment, the hinge shaft 12 is fixedly provided on the limiting head 13. Optionally, the hinge shaft 12 is welded to the limiting head 13.

[0053] In this embodiment, the first limiting portion 221 and the second limiting portion 222 are integrally formed. Since the structures of the first limiting portion 221 and the second limiting portion 222 are simple, the integral formation can avoid the process of assembling the split first limiting portion 221 and the second limiting portion 222, and also avoid using external connecting parts such as screws and bolts.

[0054] In summary, the limiting structure for rapid battery replacement provided in this embodiment has a simple structure, is convenient to operate, can realize the switching between the locked and unlocked states without disassembly and assembly, and can fully limit the battery.

[0055] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
