[0036] The gear 131 is connected to the output shaft 141 , and the rack 132 is connected to the supporting platform 12 and is suitable for meshing with the gear 131 .

[0037] Specifically, the gear 131 can be connected to the output shaft 141, so that when the driving part drives the output shaft 141 to rotate, the output shaft 141 can drive the gear 131 to rotate. At the same time, since the driving part is fixed to the base 11, and the rack 132 and the gear 131 are in meshing transmission cooperation, when the gear 131 rotates, the rack 132 can be matched through the gear 131 and the rack 132, so that the rack 132 can move relative to the base 11, and then the movement of the rack 132 can drive the support platform 12 to move, so as to adjust the position of the support platform 12.

[0038] In addition, in some specific embodiments of the present utility model, the driving part includes: a motor 142, a reduction box 143 and a coupling 144, wherein the motor 142 is arranged on the base 11, the shaft of the motor 142 is connected to the power input end of the reduction box 143, and the coupling 144 is connected to the power output end of the reduction box 143 and the gear 131. In this way, the motor 142 can provide power, and the reduction box 143 and the coupling 144 can play a good role in transmitting power and torque, which is conducive to improving the reliability and efficiency of the power transmission of the driving part, and improving the working reliability and safety of the support platform 12.

[0042] The side plate 15 is disposed on the base 11 and extends away from the base 11 in the height direction. A mounting groove is formed on the side plate 15, and the rack 132 is movably disposed in the mounting groove.

[0043] Specifically, one end of the side panel 15 can be connected to the base 11, and the side panel 15 extends away from the base 11 in the height direction. The rack 132 can be set in the installation groove and can move in the height direction relative to the installation groove, so as to realize the movement of the support platform 12 in the height direction, so that the support platform 12 has the function of rising and falling. By setting the side panel 15, on the one hand, the side panel 15 has a certain length in the height direction, which can separate the support platform 12 from the base 11, so as to reserve enough space for the movement of the support platform 12 and the disassembly and assembly of the battery pack 2, which can ensure the normal operation of the battery pack tooling 1 and improve the convenience of battery replacement operation; on the other hand, the side panel 15 can provide an installation position for the rack 132, and support and protect the rack 132, which is conducive to extending the life of the rack 132 and improving the movement reliability of the support platform 12.

[0044] like Figure 1 As shown, according to some embodiments of the present invention, the rack 132 is constructed in two and is respectively connected to both ends of the support platform 12 in the width direction.

[0045] Specifically, the two racks 132 can be both connected to the support platform 12, and the two racks 132 can be spaced apart in the width direction of the support platform 12, and the two racks 132 can be opposite to each other in the width direction of the support platform 12. In this way, the two racks 132 can respectively support and transmit power to the support platform 12 at both ends in the width direction of the support platform 12, which can effectively improve the horizontality, movement stability and accuracy of the support platform 12, help to enhance the supporting strength of the support platform 12 for the battery pack 2, and improve the accuracy of the position adjustment of the support platform 12.

[0046] In addition, in some specific embodiments of the present invention, the side plates 15 are configured as two side plates 15 arranged opposite to each other in the width direction of the base 11, and at least parts of the end surfaces of the two side plates 15 facing each other are recessed away from each other to form mounting grooves corresponding to the two gears 131; the gears 131 are configured as two gear racks 132 corresponding to each other; the reduction boxes 143 are configured as two gear racks 143 corresponding to each other and arranged at intervals in the width direction of the base 11, and a connecting shaft 145 is provided between the two reduction boxes 143 to synchronize the two reduction boxes 143. In this way, the two gear racks 132 can be guaranteed to have good working performance, and the movement stability and accuracy of the support platform 12 can be further improved.

[0047] like Figure 1 As shown, according to some embodiments of the utility model, the battery pack tooling 1 also includes: a self-locking structure, which is arranged at the output end of the transmission assembly 13 and / or the input end of the transmission assembly 13, and is suitable for self-locking when the support platform 12 moves to a preset position.

[0048] Specifically, the self-locking structure can be only provided at the output end of the transmission assembly 13, but not at the input end of the transmission assembly 13; the self-locking structure can also be only provided at the input end of the transmission assembly 13, but not at the output end of the transmission assembly 13; the arrangement of the self-locking structure can also be that both the output end of the transmission assembly 13 and the input end of the transmission assembly 13 are provided with the self-locking structure. When the driving part drives the support platform 12 to move to a preset position that cooperates with the battery pack 2 through the transmission assembly 13, the self-locking structure can block the power transmission between the driving part and the support platform 12 to lock the support platform 12 in this position. For example, the self-locking structure can be in the form of a ratchet and a pawl, a worm wheel and a worm, etc. The self-locking structure can prevent the support platform 12 and the rack 132 from sliding, which can effectively improve the stability of the battery pack 2 placed on the support platform 12, and can optimize the working performance of the battery pack tooling 1 and the safety performance of battery replacement.

[0049] like Figure 2 As shown, according to some embodiments of the present invention, a first limiting portion 121 is formed on a side of the support platform 12 away from the base 11 , and a second limiting portion 21 suitable for cooperating with the first limiting portion 121 is formed on the battery pack 2 .

[0050] Specifically, a first limiting portion 121 may be formed on the support platform 12, and a second limiting portion 21 may be formed on the battery pack 2, and the first limiting portion 121 is suitable for limiting cooperation with the second limiting portion 21. When the support platform 12 and the battery pack 2 cooperate, the first limiting portion 121 may cooperate with the second limiting portion 21 to play a guiding and limiting role between the support platform 12 and the battery pack 2, which is conducive to the correct alignment between the support platform 12 and the battery pack 2, and improves the connection stability of the support platform 12 and the battery pack 2 after alignment, so as to further improve the efficiency and safety of disassembly and assembly of the battery pack 2.

[0051] like Figure 2 As shown, according to some embodiments of the present utility model, one of the first limiting portion 121 and the second limiting portion 21 is configured as a snap-fit ​​protrusion, and the other is configured as a snap-fit ​​groove.

[0052] Specifically, one of the first limiting portion 121 and the second limiting portion 21 can be configured as a snap-fitting protrusion, and the other can be configured as a snap-fitting groove. For example, at least a portion of the side of the support platform 12 away from the base 11 can be recessed toward the direction close to the base 11 and formed into a snap-fitting groove. At least a portion of the end surface of the battery pack 2 facing the support platform 12 can protrude from the battery pack 2 and form a snap-fitting protrusion. During the cooperation between the support platform 12 and the battery pack 2, the snap-fitting protrusion can extend into the snap-fitting groove and abut against at least a portion of the inner wall of the snap-fitting groove to limit the support platform 12 and the battery pack 2, thereby limiting the movement between the support platform 12 and the battery pack 2 and improving the support stability of the battery pack 2 during disassembly and assembly. In addition, when the battery pack 2 is disassembled and assembled, the snap-fitting protrusion can also be easily separated from the snap-fitting groove to release the limit between the battery pack 2 and the support platform 12, which is conducive to improving the working efficiency of the support platform 12.

[0053] In addition, in some specific embodiments of the utility model, the snap-fit ​​protrusion includes a first protrusion 1211 extending in the first direction and a second protrusion 1212 extending in the second direction, and the snap-fit ​​groove includes a first groove 211 suitable for snap-fitting with the first protrusion 1211 and a second groove 212 suitable for snap-fitting with the second protrusion 1212, wherein the first direction and the second direction intersect. Through the cooperation between the first protrusion 1211 and the first groove 211, and the cooperation between the second protrusion 1212 and the second groove 212, the first protrusion 1211, the second protrusion 1212, the first groove 211, and the second groove 212 can limit the support platform 12 and the battery pack 2 in multiple directions, which can improve the connection stability between the support platform 12 and the battery pack 2, and improve the support reliability of the support platform 12 for the battery pack 2.

[0054] Preferably, the first direction and the second direction are orthogonal, and the first protrusion 1211 is constructed to be at least two spaced apart in the second direction, so that the first protrusion 1211 and the second protrusion 1212 jointly define a rectangular protrusion, and the first groove 211 and the second groove 212 are arranged as rectangular grooves corresponding to the rectangular protrusion, which is beneficial to further enhance the connection stability between the support platform 12 and the battery pack 2.

[0055] like Figure 1 As shown, according to some embodiments of the present invention, the battery pack tooling 1 further includes: a support rod 16 , and the support rod 16 is arranged between the support platform 12 and the transmission assembly 13 .

[0056] Specifically, one end of the support rod 16 in the extension direction can be connected to the side of the support platform 12 facing the base 11 in the height direction, and the other end of the support rod 16 in the extension direction can be connected to the output end of the transmission assembly 13. When the driving unit drives the transmission assembly 13, the transmission assembly 13 can drive the support rod 16 to move, and the movement of the support rod 16 can drive the support platform 12 to move, so that the support platform 12 can be adjusted to a position suitable for supporting the battery pack 2 to be removed or the battery pack 2 to be installed, etc., so as to facilitate the battery replacement operation. By setting the support rod 16, on the one hand, the support rod 16 can have a good supporting and bearing effect on the support platform 12, and the support rod 16 can share and transfer the weight and pressure of the battery pack 2 on the support platform 12 to other parts of the battery pack tooling 1, thereby improving the stability and bearing capacity of the support platform 12; on the other hand, the support rod 16 itself has a certain length, which can further expand the position adjustment range of the support platform 12 and further improve the adaptability of the support platform 12 to different battery packs 2, so that the battery pack 2 can be lifted and lowered to a suitable position as needed for disassembly, assembly and replacement.

[0057] like Figure 1 As shown, according to some embodiments of the present invention, the battery pack tooling 1 further includes: a sensor 17 , which is disposed on the support platform 12 and is suitable for detecting the distance between the support platform 12 and the battery pack 2 .

[0058] Specifically, the sensor 17 can be arranged on the side of the support platform 12 facing the base 11 in the height direction to avoid the cooperation between the battery pack 2 and the support platform 12. The sensor 17 is used to detect the distance between the support platform 12 and the battery pack 2. When the sensor 17 detects that the distance between the support platform 12 and the battery pack 2 reaches a preset distance, that is, when the support platform 12 moves to a preset position, the sensor 17 can feedback a signal to the drive unit to stop the drive unit from working and put it in a self-locking state. Therefore, by setting the sensor 17, the working automation of the battery pack tooling 1 can be improved, and the working safety can be improved.
