[0048] Before the embodiment of the present application is described, the basic concepts and terms involved in the embodiment of the present application are explained for the convenience of understanding the technical solution of the present application:

[0049] The guide rail type rubber wheel system is one of the important components of the green traffic solution. Since the guide rail type rubber wheel system runs on the support rail (i.e. rail beam) erected in the air, it helps to solve urban traffic congestion, improve urban traffic efficiency, help to build a modern comprehensive transportation system, break through the urban traffic microcirculation, and improve the happiness of residents' travel.

[0050] Among them, the guide rail type traffic system carries a power battery system, etc. The power battery system includes a power battery pack, which is usually arranged at the bottom of the vehicle body and fixedly connected with the vehicle body. In this way, in an emergency, even if the vehicle is powered off, it can continue to travel by starting the power battery, ensuring the safety of passengers.

[0051] In order to facilitate the dismounting or maintenance of the power battery pack, the embodiment of the present application provides a battery pack dismounting and mounting equipment for assisting in dismounting the battery pack.

[0052] In some embodiments, the battery pack installation and removal equipment includes a base, a sliding lifting structure, and a working platform. The sliding lifting structure is disposed on the base, and the working platform is disposed on the sliding lifting structure. The working platform is used to support the battery pack, and the sliding lifting structure drives the working platform to rise and fall. Thus, when disassembling the battery pack, the battery pack installation and removal equipment moves to below the battery pack, and the sliding lifting structure drives the working platform to rise and fall, so that the working platform supports the battery pack below. When the fixed connection between the battery pack and the vehicle body is released, the battery pack is located on the working platform, and the sliding lifting structure drives the working platform and the battery pack to descend, so that the battery pack moves with the battery pack installation and removal equipment to the outside of the vehicle body. When it is necessary to install the battery pack, the battery pack is placed on the working platform, and the entire battery pack installation and removal equipment needs to be moved to below the vehicle body. According to the height of the battery pack installation position, the sliding lifting structure drives the working platform to rise and fall, so that the battery pack reaches the installation position and is fixed to the vehicle body, thereby completing the battery installation.

[0053] However, when the battery pack is multi-layered, meaning multiple battery packs are vertically spaced and stacked at the bottom of the vehicle body, there is insufficient space between adjacent battery packs to accommodate the battery pack disassembly and assembly equipment when it is necessary to disassemble the multi-layered battery packs independently. Therefore, the battery pack disassembly and assembly equipment provided in the above embodiments can only disassemble the bottommost battery pack or all battery packs when disassembling a multi-layered battery pack, and cannot disassemble each individual battery pack in the multi-layered battery pack independently. In other words, the battery pack disassembly and assembly equipment provided in the above embodiments is suitable for disassembling and assembling a single battery pack, but not for disassembling multi-layered battery packs independently.

[0054] To address the problem of individual battery pack disassembly in multi-layer battery packs, this application designs a battery pack disassembly and assembly device for disassembling battery packs in a guide rail type rubber wheel system. This device allows for the independent disassembly of individual battery packs in a multi-layer battery pack, thereby facilitating the replacement, maintenance, and upkeep of each battery pack.

[0055] Figure 1 This is a schematic diagram of a battery pack disassembly and assembly device provided in an embodiment of this application. Please refer to... Figure 1 As shown, the battery pack disassembly and assembly device 10 provided in this application embodiment includes a device body 100 and a telescopic mechanism 200. The device body 100 can be raised and lowered along a first direction to facilitate the disassembly and assembly of battery packs at different heights. The telescopic mechanism 200 is disposed on the device body 100 and has a telescopic member 210. The telescopic member 210 can be extended and retracted along a second direction to at least partially extend out of the device body 100 or retract into the device body 100. The first direction is, for example, a vertical direction, and the second direction is, for example, a horizontal direction that is perpendicular or approximately perpendicular to the vertical direction.

[0056] When disassembling one of the at least two battery packs 20, firstly, the battery pack disassembly and assembly device 10 is located outside one side of the support rail 30. The device body 100 is raised and lowered to the height of the battery pack 20 to be disassembled. Then, the telescopic member 210 extends from one end of the device body 100 near the support rail 30 and extends to the bottom of the battery pack 20 to be disassembled. After that, the fixed connection between the battery pack 20 and the vehicle body is released, so that the telescopic member 210 is supported at the bottom of the battery pack 20. Thus, when the telescopic member 210 retracts towards the device body 100, the battery pack 20 located on the telescopic member 210 is removed from the at least two battery packs 20. Therefore, in this embodiment of the application, By providing a telescopic mechanism 200 on the liftable device body 100, when disassembling the battery pack 20, only the telescopic component 210 in the telescopic mechanism 200 extends to the bottom of the battery pack 20. The device body 100 does not need to be moved as a whole to the bottom of the battery pack 20. Therefore, the gap between two adjacent battery packs 20 only needs to be large enough to accommodate the telescopic component 210. There is no need to provide a large space between two adjacent battery packs 20. Each battery pack 20 in the multi-layer battery pack 20 can be disassembled and assembled individually without interference from other battery packs 20. This reduces the difficulty of disassembling and maintaining any battery pack in the multi-layer battery pack, making it easier to disassemble, assemble, and maintain each battery pack 20 in the multi-layer battery pack.

[0057] In some embodiments, the telescopic member 210 may be a telescopic plate, a telescopic rod, or other telescopic structure, and the telescopic member 210 has a certain load-bearing support strength to improve the reliability of supporting the battery pack 20.

[0058] For example, such as Figures 1 to 3 As shown, the telescopic component 210 consists of two telescopic arms 211, which are spaced apart along a third direction. For example, the two telescopic arms 211 are located near the two sides of the device body 100 along the third direction. The third direction has an angle with the first direction and the second direction, respectively. For example, the third direction is perpendicular or approximately perpendicular to the first direction and the second direction. The telescopic arms 211 can extend and retract relative to the device body 100 along the second direction to extend to the bottom of the battery pack 20 to be disassembled. When the telescopic arms 211 retract, the battery pack 20 located on them is removed, thereby realizing the disassembly, assembly, and maintenance of each layer of battery pack 20.

[0059] Of course, the telescopic component 210 includes, but is not limited to, two telescopic arms 211. The number of telescopic arms 211 can be two, four, six, eight, etc. All telescopic arms 211 are divided into two groups, and the same number of the two groups of telescopic arms 211 are spaced apart along a third direction to enhance the support strength of the telescopic arms 211 for the battery pack 20.

[0060] In some embodiments, two adjacent battery packs 20 of the multi-layer battery pack 20 can have a gap therebetween, so that the telescopic member 210 can extend into the bottom of the battery pack 20 to be disassembled, or, the bottom of each layer of battery pack 20 has a protrusion protruding out of the edge of the battery pack 20, so that the telescopic member 210 can extend into the bottom of the protrusion of the battery pack 20, thereby disassembling the battery pack 20, so that the gap between the two adjacent layers of battery pack 20 can be omitted or reduced, thereby reducing the overall volume of the power battery composed of the battery pack 20, and at the same time, it is not necessary to consider the problem of reserving space at the bottom of each layer of battery pack 20 for the battery pack disassembling device 10 when disassembling the battery pack 20.

[0061] The battery pack disassembling device 10 provided by the embodiments of the present application is suitable for disassembling and assembling the multi-layer battery pack 20. For example, the battery pack disassembling device 10 is used for disassembling and assembling two-layer battery pack 20, as shown in FIG. 1, the device body 100 is raised in the first direction, so that the height of the telescopic member 210 in the telescopic mechanism 200 is located at the bottom of the upper layer of battery pack 20, and through the contraction of the telescopic member 210 in the second direction, the upper layer of battery pack 20 can be disassembled from the upper layer, or, after the contraction of the telescopic member 210 in the second direction, the battery pack 20 to be installed is placed on the telescopic member 210, and through the extension of the telescopic member 210 in the second direction, the battery pack 20 to be installed can be moved to the position to be installed, and then the battery pack 20 is fixed by screws or the like. Figure 1 Figure 2 As shown in FIG. 2, the device body 100 is lowered in the first direction, so that the height of the telescopic member 210 in the telescopic mechanism 200 is located at the bottom of the lower layer of battery pack 20, and through the contraction of the telescopic member 210 in the second direction, the lower layer of battery pack 20 can be disassembled from the lower layer, or, after the contraction of the telescopic member 210 in the second direction, the battery pack 20 to be installed is placed on the telescopic member 210, and through the extension of the telescopic member 210 in the second direction, the battery pack 20 to be installed can be moved to the position to be installed in the lower layer, and the battery pack 20 is fixed with the vehicle body, and then the telescopic member 210 is retracted to complete the installation.

[0062] ​Of course, the battery pack dismounting device 10 can be applied to the dismounting of multi-layer battery packs 20. For example, it can be applied to the dismounting of three-layer, four-layer, five-layer, six-layer, etc. multi-layer battery packs 20. The device body 100 is lifted along the first direction so that the telescopic member 210 in the telescopic mechanism 200 is at the bottom of the battery pack 20 in the corresponding layer. The battery pack 20 in the layer can be dismounted or mounted by the telescopic movement of the telescopic member 210 along the second direction, so as to realize the dismounting and maintenance of the battery pack 20 at any height position. In addition, if the multi-layer battery packs 20 are arranged along the third direction in addition to the height direction, the battery pack dismounting device 10 can be moved along the third direction to dismount and maintain the multi-layer battery packs 20 along the third direction.

[0063] In some embodiments, as shown in Figures 1 to 3 The bottom of the vehicle body is provided with a support frame 310 on which the battery pack 20 can be mounted. The multi-layer battery packs can be arranged in layers on the support frame 310 and fixedly connected to the support frame 310 by screws, etc., so as to improve the reliability of the mounting of the battery pack 20 on the vehicle body.

[0064] In this way, the telescopic member 210 is telescoped to the bottom of any one of the multi-layer battery packs and the fixed connection between the battery pack 20 and the support frame 310 is released, so that the battery pack 20 can be dismounted by retracting the telescopic member 210.

[0065] Since the battery pack 20 has a certain weight and the telescopic member 210 is in a cantilever state when it is extended outside the device body 100, in order to improve the support reliability of the telescopic member 210 to the battery pack 20, the battery pack dismounting device 10 further comprises two oppositely arranged guide supports 300. When the battery pack 20 is dismounted, the two guide supports 300 are arranged on opposite sides of at least two layers of battery packs 20 along the third direction, and the two guide supports 300 are configured to be hung with the support frame 310 on which the battery pack 20 is fixed, so that the guide supports 300 are fixed relative to the vehicle body. Along the second direction, at least two layers of support rails 320 are arranged on the side walls of the two guide supports 300 facing each other. The telescopic arm 211 is telescoped along the corresponding support rail 320 when it is telescoped. In this way, the support rail 320 can support and guide the telescopic member 210, so as to improve the rigidity reliability of the telescopic member 210 in the telescoping direction, thereby improving the support reliability of the telescopic member 210 to the battery pack 20.

[0066] In some embodiments, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, two guide supports 300 are arranged on the support rail 30 along the third direction and in direct contact with the support rail 30, and when the battery pack 20 is disassembled, the two guide supports 300 are respectively hung with the support frames 310 distributed on both sides of the fixed battery pack 20 along the third direction, and the two guide supports 300 are hung with the support frames 310 of the fixed battery pack 20, so as to make the connection between the two more firm, and the connection between the two can be reinforced by using a cable tie, a binding rope and the like.

[0067] In some embodiments, as Figure 3 As shown, along the second direction, the side of the two guide supports 300 facing each other has at least two layers of support rails 320, and the number of the support rails 320 is consistent with the number of layers of the battery pack 20. For example, if the battery pack 20 to be disassembled has two layers, each guide support 300 has two layers of support rails 320. When the upper layer of the battery pack 20 needs to be disassembled, the device body 100 rises along the first direction, so that the telescopic arm 211 extends along the upper layer of the support rail 320 to the bottom of the upper layer of the battery pack 20, and when the telescopic arm 211 is retracted, the upper layer of the battery pack 20 is disassembled from the upper layer. When the upper layer of the battery pack 20 needs to be installed, the telescopic arm 211 is retracted along the upper layer of the support rail 320, the battery pack 20 to be installed is placed on the telescopic arm 211, and when the telescopic arm 211 is extended, the battery pack 20 is moved to the designated position of the upper layer. When the lower layer of the battery pack 20 needs to be disassembled, the device body 100 is lowered along the first direction, so that the telescopic arm 211 extends along the lower layer of the support rail 320 to the bottom of the lower layer of the battery pack 20, and when the telescopic arm 211 is retracted, the lower layer of the battery pack 20 is disassembled from the lower layer. When the lower layer of the battery pack 20 needs to be installed, the telescopic arm 211 is retracted along the lower layer of the support rail 320, the battery pack 20 to be installed is placed on the telescopic arm 211, and when the telescopic arm 211 is extended, the battery pack 20 is moved to the designated position of the lower layer.

[0068] As Figure 3 As shown, each layer of the support rail 320 includes at least two guide wheels 321, and the at least two guide wheels 321 are arranged along the second direction. The telescopic arm 211 is configured to be arranged on the guide wheels 321 and in rolling contact with the guide wheels 321, so as to increase the support strength of the telescopic arm 211 and reduce the friction of the telescopic arm 211 during the telescopic process.

[0069] The number of guide wheels 321 in each layer includes but is not limited to two, three, four, five, six, etc., which can be selected according to the length and weight of the battery pack 20 along the second direction. When the length of the battery pack 20 to be disassembled along the second direction is longer or the weight of the battery pack 20 is heavier, more guide wheels 321 can be selected for each layer to increase the supporting force of the telescopic arm 211 during the disassembly of each layer of battery pack 20, so as to avoid the deformation of the telescopic arm 211 due to the weight of the battery pack 20, which affects the normal use of the telescopic arm 211. The rolling contact between the telescopic arm 211 and the guide wheel 321 can reduce the friction of the telescopic arm 211 during the telescopic process, so that the telescopic arm 211 is more smooth during the telescopic process.

[0070] As shown in Figure 3 , the top of each telescopic arm 211 has a plurality of support blocks 212, which are arranged at intervals along the extension direction of the telescopic arm 211. The support block 212 is configured to support the battery pack 20. It can be understood that a plurality of support blocks 212 are arranged between the telescopic arm 211 and the battery pack 20 to form gaps between the support blocks 212, so as to facilitate the arrangement of the bolts on the edge of the battery pack 20, thereby keeping the telescopic arm 211 stable when supporting the battery pack 20.

[0071] For example, the position of the support block 212 and the size of the support block 212 along the second direction can be set according to the number of bolts on the bottom of the battery pack 20 corresponding to the position of the telescopic arm 211 and the length of the bolts along the second direction, so that the telescopic arm 211 supports the battery pack 20, and the position of the support block 212 avoids the bolts on the bottom of the battery pack 20.

[0072] As shown in Figure 3 , the plurality of support blocks 212 includes a first support block 213 and a second support block 214, and the sizes of the first support block 213 and the second support block 214 in the extension direction of the telescopic arm 211 are different.

[0073] In some embodiments, as shown in Figure 3 , for example, four support blocks 212 are arranged on each telescopic arm 211, including two first support blocks 213 distributed at both ends of the telescopic arm 211 and two second support blocks 214 distributed in the middle of the telescopic arm 211, so that the telescopic arm 211 supports the battery pack 20, and the positions of the first support block 213 and the second support block 214 can avoid the bolts of different sizes on the bottom of the battery pack 20.

[0074] As shown in Figure 1 , Figure 2 and Figure 3 , each guide bracket 300 has a plurality of maintenance windows 330, and the plurality of maintenance windows 330 and the at least two guide wheels 321 are arranged alternately along the second direction.

[0075] In some embodiments, in order to facilitate the maintenance of the battery pack 20 by using a wrench or other tools, a plurality of maintenance windows 330 are arranged on each guide support 300. For example, as shown in Figure 3 seven maintenance windows 330 are arranged on each guide support 300, three large maintenance windows 330 are arranged alternately with four guide wheels 321 along the second direction, and four small maintenance windows 330 are arranged side by side with the four guide wheels 321, and the arrangement of the maintenance windows 330 can reduce the weight of the guide support 300.
