Detailed Implementation

[0093] The core of this application is to provide a battery pack maintenance fixture to improve the ease of disassembly and assembly of the battery pack.

[0094] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0095] Due to limited operating space in energy storage power stations, large hoisting equipment cannot enter the power station to move battery packs. This means that when installing or maintaining battery packs in energy storage cabinets, only small transport equipment can be used to move the battery packs. However, because the battery packs are quite heavy, it is difficult for workers to lift them, making it very difficult for workers to install or replace the battery packs, resulting in low disassembly and assembly efficiency.

[0096] Therefore, such as Figures 2 to 5 As shown in the figure, this application discloses a battery pack maintenance fixture, including a base 100, a movable platform 200, a push-pull mechanism 300, a control mechanism, and a locking mechanism 400. By cooperating with small transportation equipment, the battery pack maintenance fixture solves the problem of limited operating space and difficulty in disassembling and assembling battery packs in energy storage power stations, thus improving the convenience of battery pack disassembly and assembly.

[0097] The following will combine Figures 1 to 27 The battery pack maintenance fixture disclosed in the embodiments of this application will be explained and described in detail.

[0098] Among them, such as Figures 2 to 5 As shown, the movable platform 200 is mounted on the base 100 and is movably fitted with the base 100. The base 100 contacts a working surface, which can be the ground or the support surface of a small transport device. A control mechanism connected to the movable platform 200 allows the platform to move or rotate under the control mechanism's influence, aligning it with the target position. A locking mechanism 400 on the movable platform 200 locks its position to prevent displacement during battery pack movement. A push-pull mechanism 300 is mounted on the movable platform 200 and can move along it, allowing the battery pack to be moved to or removed from the target position, thus enabling battery pack assembly and disassembly. As can be seen from the above example, the entire battery pack disassembly and assembly process does not require staff to lift or move the battery pack, which solves the problem of limited operating space in energy storage power stations and the difficulty of disassembling and assembling battery packs, and improves the convenience and efficiency of battery pack disassembly and assembly.

[0099] In some embodiments, such as Figure 1 As shown, when disassembling the battery pack inside the energy storage cabinet, a small transport device, such as a small forklift, is used to transport the battery pack maintenance tooling to the location of the energy storage cabinet where the battery pack needs to be disassembled. A control mechanism drives the movable platform 200 to move horizontally, vertically, or rotate, aligning it with the target position, namely the location of the battery pack to be disassembled within the energy storage cabinet (hereinafter referred to as the disassembly battery pack position). Simultaneously, a locking mechanism 400 installed on the movable platform 200 locks its position to prevent displacement during battery pack movement. Then, the push-pull mechanism 300 on the movable platform 200 can be moved from its initial position to the disassembly battery pack position and secured to the battery pack. The push-pull mechanism 300 is then moved back to its initial position, allowing the battery pack to be pulled out from the disassembly battery pack position. Finally, the battery pack maintenance tooling and the disassembled battery pack are transported together out of the energy storage power station using a small transport device. It should be noted that a forklift sleeve 104 is provided on the base 100 to cooperate with the forklift. When a small forklift is used to transport the battery pack maintenance fixture, the forks of the small forklift can be inserted into the forklift sleeve 104 to lift the entire battery pack maintenance fixture and transport it to the target location by the small forklift.

[0100] In other embodiments, when installing the battery pack, the battery pack is first pre-positioned on the movable platform 200 of the battery pack maintenance fixture. Then, a small transport device transports the battery pack maintenance fixture and the battery pack to the energy storage cabinet where the battery pack needs to be installed. A control mechanism drives the movable platform 200 to move, lift, or rotate, so that the movable platform 200 is aligned with the target position, i.e., the position of the battery pack to be installed inside the energy storage cabinet (hereinafter referred to as the battery pack installation position). Simultaneously, a locking mechanism 400 on the movable platform 200 locks the position of the movable platform 200 to prevent it from shifting when the battery pack is moved. At this point, the battery pack can be installed by using a push-pull mechanism 300 on the movable platform 200 to abut against the battery pack and push the battery pack from its initial position to the battery pack installation position.

[0101] It should be noted that when replacing the battery pack, the battery pack to be replaced (hereinafter referred to as the replacement battery pack location) in the energy storage cabinet can be removed first using battery pack maintenance tools and small transport equipment. Then, the new battery pack can be transported and installed at the replacement battery pack location using the same tools. The specific implementation methods for disassembling and installing the battery pack have been explained and described in the above embodiments, and will not be repeated here.

[0102] To enable the movement of the activity platform 200, such as Figure 2 As shown, the control mechanism includes a translation mechanism and a lifting mechanism 700. The translation mechanism includes a first translation mechanism 500 and a second translation mechanism 600. The first translation mechanism 500 can move the movable platform 200 along a first direction, and the second translation mechanism 600 can move the movable platform 200 along a second direction. Simultaneously, the lifting mechanism 700 can raise and lower the movable platform 200. Furthermore, the first translation mechanism 500, the second translation mechanism 600, and the lifting mechanism 700 can be independently configured, allowing the control mechanism to control the movable platform 200 to move in a single direction. It should be noted that the first direction is towards the target position, and the second direction is perpendicular to the first direction on the horizontal plane.

[0103] For ease of understanding, the first direction can be defined as the x-direction, the central axis of the movable platform 200 in the x-direction can be defined as the x-axis, the second direction can be defined as the y-direction, the central axis of the movable platform 200 in the y-direction can be defined as the y-axis, the direction of lifting and lowering of the movable platform 200 perpendicular to the x-axis and y-axis can be defined as the z-direction, and the axis of the movable platform 200 in the z-direction perpendicular to the x-axis and y-axis can be defined as the z-axis.

[0104] The lifting mechanism 700 can be a pneumatic lifting mechanism, a hydraulic cylinder lifting mechanism, a screw lifting mechanism, a motor gear rack lifting motion mechanism, etc., so as to drive the movable platform 200 to move in the z direction, so as to ensure that the movable platform 200 is aligned with the target position in the z direction.

[0105] To ensure the stability and adjustability of the 200mm lifting platform, such as Figure 6 As shown, the lifting mechanism 700 may include lifting components 701 disposed at both ends of the movable platform 200, so as to realize the lifting and lowering of both ends of the movable platform 200 by means of the two lifting components 701 respectively. When the two lifting components 701 drive both ends of the movable platform 200 to move in the same direction, that is, when the two lifting components 701 rise or fall simultaneously, the lifting mechanism 700 can drive the movable platform 200 to rise and fall, while preventing the movable platform 200 from tilting to one end, thus ensuring the stability of the lifting and lowering of the movable platform 200. Of course, when the movable platform 200 tilts in the x-direction, only the lifting component 701 at one end of the movable platform 200 can be controlled, so that the movable platform 200 is in a horizontal position. When the two lifting components 701 drive the two ends of the movable platform 200 to move in opposite directions, that is, the lifting component 701 at one end of the movable platform 200 is raised and the lifting component 701 at the other end of the movable platform 200 is lowered, the lifting mechanism 700 can drive the movable platform 200 to rotate around the y-axis, thereby facilitating the adjustment of the position of the movable platform 200, so that the movable platform 200 is aligned with the target position in the z-direction, and can be kept in a horizontal position.

[0106] In some embodiments, such as Figure 6 and Figure 7 As shown, the lifting assembly 701 includes a first transmission device 7011, a second transmission device 7012, and a first drive device 7013. The first transmission device 7011 and the second transmission device 7012 are connected by a coupling 7016, and each is coupled to a corresponding lead screw 7015. Thus, the first drive device 7013 can drive the first transmission device 7011 to perform a lifting action along the lead screw 7015, and simultaneously drive the second transmission device 7012 to perform a lifting action along the lead screw 7015. This, in turn, can drive the lifting and lowering of the movable platform 200 through the first and second transmission devices 7011 and 7012. It should be noted that the first transmission device 7011 and the second transmission device 7012 can employ a helical pair transmission mechanism, a ball screw transmission mechanism, a gear and rack transmission mechanism, etc., and the first drive device 7013 can employ electric drive, hydraulic drive, etc., which are not limited here.

[0107] In some embodiments, a mounting plate 105 is provided on the base 100, and the lead screw 7015 is fixed to the mounting plate 105 via a connecting seat 7017. Thus, the first drive device 7013 can drive the first transmission device 7011 to perform a lifting action along the lead screw 7015, and simultaneously drive the second transmission device 7012 to perform a lifting action along the lead screw 7015. Therefore, the first transmission device 7011 and the second transmission device 7012 can drive the lifting and lowering of the movable platform 200. Furthermore, the lead screw 7015 can be hinged to the connecting seat 7017, which, compared to a rigid connection, effectively reduces the risk of breakage at the connection point between the lead screw 7015 and the mounting plate 105.

[0108] To prevent the mobile platform 200 from shifting in the y-direction when the battery pack is placed on it, such as... Figure 4 As shown, a floating mechanism 800 is provided between the lifting assembly 701 and the movable platform 200 so that when one side of the movable platform 200 shifts, the movable platform 200 can be automatically leveled under the action of the floating mechanism 800.

[0109] In some embodiments, such as Figures 8 to 10 As shown, the floating mechanism 800 includes a floating beam 801 connected to the movable platform 200. A floating pivot pin 8011 is provided on the floating beam 801, enabling the floating beam 801 to drive the movable platform 200 to swing around the pivot pin 8011. Simultaneously, a reset elastic element 8012 is provided on the floating beam 801, with at least two reset elastic elements 8012 symmetrically arranged on both sides of the pivot pin 8011. When one side of the movable platform 200 shifts, the movable platform 200 can return to a horizontal position under the elastic force of the corresponding reset elastic element 8012 on the floating beam 801. It should be noted that two, four, six, or more reset elastic elements 8012 can be used, and each reset elastic element 8012 is symmetrically arranged on both sides of the pivot pin 8011 to ensure that the forces on both sides of the movable platform 200 are equal, thereby guaranteeing the stability of the movable platform 200.

[0110] In some embodiments, such as Figure 8 and Figure 10As shown, the floating beam 801 has support plates 8013 at both ends, allowing it to abut against the movable platform 200. The lifting assembly 701 also includes a connecting beam 7014 connected to the first transmission device 7011 and the second transmission device 7012. The connecting beam 7014 is connected to the floating beam 801 via a floating pivot pin 8011, enabling the lifting assembly 701 to raise and lower the movable platform 200 via the connecting beam 7014 and the floating beam 801. Simultaneously, the floating beam 801 can cause the movable platform 200 to swing around the floating pivot pin 8011. In addition, the reset elastic element 8012 may include a fixed rod 8014 and a floating spring 8015 sleeved on the outside of the fixed rod 8014. One end of the fixed rod 8014 is connected to the connecting beam 7014, and the other end of the fixed rod 8014 is slidably provided with an abutment plate 8016. The abutment plate 8016 is provided on the floating crossbeam 801 so that when one side of the movable platform 200 is offset, the abutment plate 8016 on the floating crossbeam 801 corresponding to the movable platform 200 can slide along the fixed rod 8014 so that the abutment plate 8016 can compress the floating spring 8015. At this time, the floating spring 8015 generates an elastic force opposite to the offset direction of the movable platform 200, thereby restoring the movable platform 200 to a horizontal position and achieving the purpose of self-leveling of the movable platform 200.

[0111] To enable the activity platform 200 to move along the first direction, i.e., the x-direction, as follows: Figure 11 As shown, the first translation mechanism 500 includes a first slide rail 501, a slider 502, and a second driving device 503. The first slide rail 501 is mounted on the movable platform 200, and the slider 502 is mounted on the floating beam 801, with the slider 502 slidingly engaging with the first slide rail 501. The second driving device 503 is mounted on the movable platform 200 and can drive the movable platform 200 to move along a first direction.

[0112] In some embodiments, such as Figure 11As shown, to ensure the stability of the movable platform 200 moving along the first direction, two sliders 502 can be used, and the two sliders 502 are respectively fixed on the support plates 8013 at both ends of the floating beam 801. Simultaneously, two first slide rails 501 can also be used, adapted to the sliders 502. Thus, the stability of the movable platform 200 moving along the first direction is ensured through the sliding engagement between the first slide rails 501 on both sides of the movable platform 200 and the sliders 502 at both ends of the floating beam 801. Furthermore, the second driving device 503 may include a first drive motor and a first screw transmission mechanism. The first drive motor is fixed to the movable platform 200, and can drive the screw of the first screw transmission mechanism to rotate. The nut of the first screw transmission mechanism is fixed to the floating beam 801. When the screw of the first screw transmission mechanism rotates, the nut of the first screw transmission mechanism will move linearly along the axial direction of the screw, thereby causing the screw of the first screw transmission mechanism to drive the movable platform 200 to move along the first direction. Of course, the second drive device 503 can also be other devices that can drive the movable platform 200 to move, such as hydraulic telescopic rods, electric telescopic rods, etc., which are not limited here.

[0113] In order to enable the activity platform 200 to move along the second direction, i.e., the y-direction, as follows: Figure 12 As shown, the base 100 has a mounting groove 106, and the second translation mechanism 600 is disposed in the mounting groove 106 of the base 100. The lifting mechanism 700 is connected to the second translation mechanism 600, so that the lifting mechanism 700 can be driven to move along the second direction through the second translation mechanism 600, thereby driving the movable platform 200 to move along the second direction. The second translation mechanism 600 can be a lead screw translation mechanism, a gear and rack mechanism, etc., so that the movable platform 200 can be driven to move along the second direction to ensure that the movable platform 200 is aligned with the target position in the y-direction.

[0114] To ensure the stability and adjustability of the moving platform 200 along the second direction, such as Figure 12As shown, the second translation mechanism 600 may include translation components 601 disposed at both ends of the movable platform 200. The two translation components 601 can respectively drive both ends of the movable platform 200 to move along a second direction. When the two translation components 601 drive both ends of the movable platform 200 to move in the same direction, the second translation mechanism 600 can drive the movable platform 200 to move along the second direction, while preventing any end of the movable platform 200 from tilting in the horizontal plane, thus ensuring the stability of the movable platform 200's movement along the second direction. Of course, when any end of the movable platform 200 tilts in the horizontal plane, only one end of the translation component 601 of the movable platform 200 can be controlled, thereby ensuring that the movable platform 200 is aligned with the target position in the y-direction. When the two translation components 601 drive both ends of the movable platform 200 to move in opposite directions, the second translation mechanism 600 can drive the movable platform 200 to rotate around the z-axis, thereby facilitating the adjustment of the position of the movable platform 200 and ensuring that the movable platform 200 is aligned with the target position in the y-direction.

[0115] In some embodiments, such as Figure 12 As shown, the translation component 601 includes a connecting platform 6011 and a third drive device 6012, with a lifting mechanism 700 mounted on the connecting platform 6011. The third drive device 6012 can drive the connecting platform 6011 to move along a second direction, thereby causing the lifting mechanism 700 to move the movable platform 200 along the second direction. The third drive device 6012 may include a second drive motor and a second screw transmission mechanism. The second drive motor can be mounted in the mounting groove 106 of the base 100, and can drive the lead screw of the second screw transmission mechanism to rotate. The nut of the second screw transmission mechanism is fixed to the connecting platform 6011. When the lead screw of the second screw transmission mechanism rotates, the nut of the second screw transmission mechanism will move linearly along the axial direction of the lead screw, thereby causing the connecting platform 6011 to move the lifting mechanism 700 along the second direction, which in turn can move the movable platform 200 along the second direction. Of course, the third drive device 6012 can also be other devices that can drive the connecting platform 6011 to move, such as hydraulic telescopic rods, electric telescopic rods, etc., which are not limited here.

[0116] To enable the push-pull mechanism 300 to move on the movable platform 200, thereby moving the battery pack, such as... Figures 13 to 22 As shown, the push-pull mechanism 300 may include a push-pull component and a drive mechanism 302, and the push-pull component and the drive mechanism 302 are detachably connected, so that the push-pull component can move along the first direction on the movable platform 200 under the drive of the drive mechanism 302, so as to drive the battery pack to move on the movable platform 200, thereby realizing the installation and removal of the battery pack.

[0117] Among them, such as Figures 13 to 22As shown, the push-pull assembly may include a pushing component 303 and a traction component 304. When installing the battery pack, the pushing component 303 can be connected to the drive mechanism 302 so that when the pushing component 303 moves, the battery pack can be pushed to the target position. When removing the battery pack, the traction component 304 can be connected to the drive mechanism 302 so that when the traction component 304 moves, the battery pack can be pulled out from the target position, thereby achieving the removal of the battery pack.

[0118] In some embodiments, such as Figures 13 to 17 As shown, the pushing component 303 may include a first push-pull base plate 301 and pushing frames 3031 disposed at both ends of the first push-pull base plate 301. An extension rod 3032 is detachably connected to the pushing frame 3031. Due to the limited operating space of the energy storage power station, when pushing the battery pack on the movable platform 200, the pushing frames 3031 at both ends of the first push-pull base plate 301 first abut against one end of the battery pack. By moving the first push-pull base plate 301, the pushing frames 3031 push the battery pack until the other end of the battery pack extends out of the movable platform 200. Figure 16 As shown; then, the first push-pull base plate 301 is moved away from the battery pack, causing the pusher frame 3031 to detach from the battery pack. At this time, the extension rod 3032 can be installed on the pusher frame 3031. By moving the first push-pull base plate 301, the extension rod 3032 on the pusher frame 3031 is further pushed onto the battery pack until the battery pack is pushed to the target position, thereby realizing the installation of the battery pack. Figure 17 As shown in the example above, by designing the push component 303 with multi-level push functionality, the problem of limited operating space in energy storage power stations, which makes battery pack installation difficult, can be solved, thus improving the ease of battery pack installation.

[0119] In some embodiments, such as Figure 13As shown, the pusher frame 3031 may include a connecting plate 3033 and a push plate 3034 disposed on the connecting plate 3033. A slot for mounting a first push-pull base plate 301 is provided on the connecting plate 3033, allowing the end of the first push-pull base plate 301 to be disposed within the slot and fixed by bolts. Pushing the first push-pull base plate 301 then moves the pusher frame 3031. A fixing plate 3037 is also provided on the connecting plate 3033, with the push plate 3034 and fixing plate 3037 positioned opposite each other at both ends of the connecting plate 3033. A limiting groove for limiting the extension rod 3032 is provided on the push plate 3034, and a positioning rod 3035 for positioning the extension rod 3032 is connected between the push plate 3034 and the fixing plate 3037. When installing the extension rod 3032, one end of the positioning rod 3035 is fixed in the threaded hole of the fixing plate 3037, and the other end of the positioning rod 3035 is engaged in the limiting groove of the push plate 3034. At the same time, the extension rod 3032 and the end of the positioning rod 3035 in the limiting groove are threadedly connected, thereby realizing the installation of the extension rod 3032 and the push frame 3031.

[0120] Of course, in the above embodiments, the extension rod 3032 can also be positioned and installed by extending the extension rod 3032. Limiting grooves are provided on both the fixing plate 3037 and the push plate 3034. When installing the extended extension rod 3032, simply snap both ends of the extended extension rod 3032 into the limiting grooves on the push plate 3034 and the fixing plate 3037, respectively. It should be noted that the connection between the extension rod 3032 and the push frame 3031 can be achieved using, but is not limited to, the connection methods described in the above embodiments. Pin connections, plug-in connections, etc., can also be used, which are not limited here.

[0121] To ensure the stability of the extension rod 3032 pushing the battery pack, a pushing block 3036 that abuts against the battery pack can be provided on the extension rod 3032, and the cross-sectional area of ​​the pushing block 3036 is larger than the cross-sectional area of ​​the extension rod 3032, so as to increase the contact area between the extension rod 3032 and the battery pack and ensure the stability of the extension rod 3032 pushing the battery pack.

[0122] In some embodiments, such as Figures 18 to 22As shown, the traction assembly 304 may include a second push-pull base plate 301a, a pulley assembly 3041, and fasteners 3042 located at both ends of the second push-pull base plate 301a. The pulley assembly 3041 is disposed on the second push-pull base plate 301a, and the fasteners 3042 and the pulley assembly 3041 are connected by a traction member 3046. When disassembling the battery pack, the fasteners 3042 are connected to one end of the battery pack, and the second push-pull base plate 301a is moved away from the target position until the battery pack is disengaged from the target position. At this time, the other end of the battery pack is in the position extending out of the movable platform 200. Then, the traction member 3046 is further tightened by the pulley assembly 3041, so that the battery pack continues to move away from the target position under the pull of the traction member 3046 until the battery pack is completely located on the movable platform 200, thereby realizing the disassembly of the battery pack. Figure 22 As shown in the example above, by designing the traction component 304 with multi-stage traction, the problem of limited operating space in energy storage power stations, which makes battery pack disassembly difficult, can be solved, thus improving the ease of battery pack disassembly. It should be noted that the traction component 3046 can be made of flexible components such as steel wire rope, nylon rope, or iron ring chain, and the fastener 3042 can be made of eye bolts, hook bolts, etc., which are not limited here.

[0123] In some embodiments, such as Figures 18 to 20 As shown, the pulley assembly 3041 includes fixed pulleys 3043 and limiting shafts 3044. There are at least two fixed pulleys 3043, and each fixed pulley 3043 is connected to fasteners 3042 at both ends of the second push-pull base plate 301a via traction members 3046. The fixed pulleys 3043 can be mounted on the second push-pull base plate 301a via pulley pins 3045. Limiting shafts 3044 are provided at corresponding positions on the fixed pulleys 3043 to restrict the traction members 3046 to the fixed pulleys 3043, effectively preventing the traction members 3046 from detaching from the fixed pulleys 3043.

[0124] To ensure the synchronous pulling of the fasteners 3042 at both ends of the second push-pull base plate 301a, such as Figure 20 As shown, four fixed pulleys 3043 can be used, and each fixed pulley 3043 is spaced apart on the second push-pull base plate 301a. The fixed pulleys 3043 are connected by traction members 3046, so that when the fixed pulleys 3043 are rotated, the fasteners 3042 at both ends of the second push-pull base plate 301a can be pulled synchronously. It should be noted that the number of fixed pulleys 3043 can also be three, five, or more; this is not limited here.

[0125] In the above embodiments, the pushing component 303 and the traction component 304 can also share a common push-pull base plate to reduce the cost of battery pack maintenance tooling. In some embodiments, when the pushing component 303 needs to be assembled, the end of the push-pull base plate is placed in a slot and fixed by bolts, so that the battery pack can be moved by pushing the push-pull base plate to drive the pushing frame 3031. When the traction component 304 needs to be assembled, the pushing frames 3031 at both ends of the push-pull base plate can be removed first, and then the pulley assembly 3041 can be installed on the push-pull base plate. At the same time, the fasteners 3042 located at both ends of the push-pull base plate are connected to the pulley assembly 3041 through the traction member 3046, so that the battery pack connected to the fasteners 3042 can be moved by pulling the push-pull base plate.

[0126] In order to enable the push-pull assembly to move along a first direction on the movable platform 200 under the drive of the drive mechanism 302, in some embodiments, such as Figure 16 , Figure 17 , Figure 21 and Figure 22 As shown, the drive mechanism 302 includes a second slide rail 3021, a mounting base 3022, and a fourth drive device 3023. The second slide rail 3021 is mounted on the movable platform 200 and extends from one end of the platform 200 to the other. The mounting base 3022 is mounted on the second slide rail 3021 and is slidable along it. A push-pull assembly is detachably mounted on the mounting base 3022. Furthermore, the fourth drive device 3023 is mounted on the movable platform 200 and can drive the mounting base 3022 to slide.

[0127] In some embodiments, the fourth driving device 3023 may include a third driving motor and a third screw transmission mechanism. The third driving motor may be located at one end of the movable platform 200, and it drives the lead screw of the third screw transmission mechanism to rotate. The nut of the third screw transmission mechanism is fixed to the mounting base 3022. When the lead screw of the third screw transmission mechanism rotates, the nut of the third screw transmission mechanism moves linearly along the axial direction of the lead screw, thereby causing the mounting base 3022 to drive the push-pull base plate 301 to move in the first direction. Of course, the fourth driving device 3023 may also employ other devices capable of driving the push-pull base plate 301 to move, such as a hydraulic telescopic rod or an electric telescopic rod, which are not limited herein.

[0128] In some embodiments, such as Figure 14 and Figure 19As shown, the push-pull assembly is provided with a mounting pin 3012, and the mounting base 3022 is provided with a mounting hole that mates with the mounting pin 3012. When assembling the push-pull assembly, simply insert the mounting pin 3012 on the push-pull assembly into the mounting hole on the mounting base 3022, thereby improving the ease of assembly and disassembly of the push-pull assembly. Figure 21 As shown. Of course, the push-pull assembly and the mounting base 3022 can also be connected by bolts, snap-fit, or other methods, which are not limited here.

[0129] The mounting pins 3012 can be respectively disposed on the first push-pull base plate 301 and the second push-pull base plate 301a. When it is necessary to assemble the pushing component 303, simply insert the mounting pin 3012 on the first push-pull base plate 301 into the mounting hole on the mounting base 3022. When it is necessary to assemble the traction component 304, simply insert the mounting pin 3012 on the second push-pull base plate 301a into the mounting hole on the mounting base 3022.

[0130] In addition, to facilitate the disassembly and assembly of push-pull components, such as Figures 13 to 22 As shown, a first grip portion 3011 is provided on the push-pull assembly. The first grip portion 3011 can be a handle provided on the first push-pull base plate 301 and the second push-pull base plate 301a, and the handle can be hinged to the first push-pull base plate 301 and the second push-pull base plate 301a respectively through a hinge axis, so that the handle can be folded along the hinge axis. When it is necessary to install or remove the push assembly 303 or the traction assembly 304, the operator can install or remove the push assembly 303 or the traction assembly 304 by gripping the handle; after the push assembly 303 or the traction assembly 304 is removed, the operator can fold the handle along the hinge axis, so that the push assembly 303 and the traction assembly 304 can be stored easily.

[0131] To achieve locking of the locking mechanism 400 to the position of the movable platform 200, such as... Figures 23 to 26 As shown, the locking mechanism 400 includes a locking pin 401 disposed on the movable platform 200, which can engage with a pin hole at the target position.

[0132] In some embodiments, such as Figure 26 As shown, the movable platform 200 has a first surface and a second surface arranged opposite to each other. The first surface of the movable platform 200 is used to place the battery pack, and locking pins 401 are disposed on the second surface of the movable platform 200 to avoid interfering with the movement of the battery pack. There are two locking pins 401, symmetrically distributed on both sides of the second surface of the movable platform 200. Wherein, as... Figures 23 to 25As shown, the locking pin 401 includes a pin component and a driving component. The pin component includes a locking pin 4012 and a pin seat 4011. The locking pin 4012 can be fixed to the second surface of the movable platform 200 through the pin seat 4011. The driving component includes an electric push rod 4014 and a push rod support 4015. The locking pin 4012 is locked and released by the extension and retraction of the electric push rod 4014. The fixed end of the electric push rod 4014 is connected to the push rod support 4015. Both ends of the electric push rod 4014 can be connected by a joint hinge pin 4013, thereby ensuring traction force and swing floating. It should be noted that the driving component can also be a pneumatic telescopic rod, a hydraulic telescopic rod, etc., which is not limited here.

[0133] In some embodiments, such as Figure 26 As shown, when the operator moves the battery pack maintenance tool to the target energy storage cabinet position, the locking pin 4012 of the locking mechanism 400 extends under the drive of the electric push rod 4014 until it is inserted into the pin holes on both sides of the energy storage cabinet door frame, thereby realizing the positioning and locking between the energy storage cabinet and the movable platform 200, thus ensuring the stability of the battery pack maintenance tool during use.

[0134] To facilitate the maintenance of mobile battery packs, such as Figures 2 to 4 As shown, a movable wheel 101 is provided on the base 100, and the movable wheel 101 and the base 100 can be detachably connected by bolts, snap-fit, plug-in or other means.

[0135] In some embodiments, such as Figure 3 As shown, the base 100 is provided with at least two supports 102 in a direction perpendicular to the working plane, and the distances between the two supports 102 and the working plane are not equal, that is, the heights of the two supports 102 from the working plane are not equal. This is so that when the vertical space of the target position is limited, the overall height of the battery pack maintenance tool can be reduced by installing the moving wheels 101 on the supports 102 at a higher position, thereby solving the problem of limited vertical space at the target position.

[0136] In some embodiments, such as Figure 3As shown, the base 100 has two supports 102 arranged along a direction perpendicular to the working plane. For ease of understanding, the two supports 102 are defined as the first support and the second support, respectively. The first support can be located on the bottom surface of the base 100, and the second support can be located on the side surface of the base 100, creating a height difference between the first and second supports. This allows the battery pack maintenance fixture to adapt to various extreme working conditions, improving its adaptability. Of course, the number of supports 102 on the base 100 along the direction perpendicular to the working plane can be, but is not limited to, two; three, four, or more can also be used. Furthermore, the supports 102 located on the side surface of the base 100 can be staggered to avoid mutual interference.

[0137] It should be noted that the movable wheel 101 can also be connected to the base 100 via a lifting device, thereby allowing the height of the battery pack maintenance fixture to be adjusted via the lifting device. The lifting device can be a hydraulic lifting mechanism, a pneumatic lifting mechanism, a screw drive mechanism, a worm gear mechanism, etc., which will not be elaborated upon here.

[0138] To prevent the battery pack on the mobile platform 200 from detaching from the mobile platform 200 during the transfer of battery pack maintenance fixtures, such as Figure 2 As shown, a limiting member 201 is detachably provided at one end of the movable platform 200, and a second gripping part 204 can be provided at the other end of the movable platform 200. The limiting member 201 and the second gripping part 204 can limit the battery pack in a first direction on the movable platform 200 to prevent the battery pack from detaching from the movable platform 200 in that direction. The second gripping part 204 can be a handle provided on the movable platform 200, which, while limiting the battery pack, allows the operator to easily move the battery pack maintenance fixture using the handle. Simultaneously, limiting plates 202 are provided on both sides of the movable platform 200 to prevent the battery pack from detaching from the movable platform 200 in a second direction.

[0139] In addition, the limiting plates 202 on both sides of the movable platform 200 can guide and limit the movement of the battery pack, preventing it from shifting during movement on the movable platform 200. Simultaneously, symmetrical adjustment handwheels 203 for adjusting the battery pack position are provided on both sides of the movable platform 200, and each handwheel 203 has a contact end. When the battery pack shifts from its normal position on the movable platform 200, rotating the adjustment handwheel 203 will push the battery pack back to its normal position by moving its contact end. It should be noted that there can be two, four, or six adjustment handwheels 203, etc., which is not limited here.

[0140] like Figure 27As shown, the battery pack maintenance fixture also includes a handle 900 for controlling the adjustment mechanism and the push-pull mechanism 300. The handle 900 is equipped with a start knob 901 and an emergency stop knob 902 for controlling the start and stop of the battery pack maintenance fixture, as well as a lifting button 903, a flip button 904, a first-direction translation button 908, a second-direction translation button 905, a rotation button 906, and a push-pull button 907 for controlling the operation of the adjustment mechanism and the push-pull mechanism 300.

[0141] In some embodiments, such as Figure 27 As shown, the start knob 901 and emergency stop knob 902, which are not used during operation, are placed on the top surface of the handle 900, which is the most conspicuous and does not require two-handed operation. The lift button 903 and flip button 904 are respectively arranged at the positions operated by the index fingers of the operator's left and right hands, that is, on the two opposite sides of the handle 900. This allows the operator to lift the handle along the Z-axis and flip it around the Y-axis using two buttons arranged vertically on the sides of the handle 900. The second direction translation button 905 and rotation button 906 are respectively arranged on the left and right sides of the top surface of the handle 900 for easy operation by the operator's left and right thumbs. The first direction translation button 908 is arranged on the side of the handle 900 closest to the operator for easy operation by the operator's thumb. The push-pull button 907 is arranged on the top surface of the handle 900 and close to the operator's side, so that the operator can hold the handle 900 with one hand and operate the button with the other hand. To achieve Y-axis translation, operate the second-direction translation button 905; to achieve Z-axis lifting, operate the lifting button 903; to achieve Y-axis flipping, operate the flipping button 904, and so on. The operation is straightforward and will not be elaborated further here. As shown in the example above, the layout of the control buttons on the handle 900 corresponds to the movement layout of the battery pack maintenance fixture, making it easier for operators to control the fixture and improving its ease of use.

[0142] Of course, labels for the corresponding function buttons can also be set on the handle 900 to prevent operators from accidentally operating the buttons on the handle 900.

[0143] It should be noted that a cable connector 909 is provided on the side of the handle 900 away from the operator, so that the handle 900 can be connected to the battery pack maintenance fixture via cable to achieve control signal transmission. Of course, a Bluetooth control module can also be built into the battery pack maintenance fixture and the handle 900, so that the handle 900 can be operated after successful Bluetooth pairing with the battery pack maintenance fixture, reducing the use of cables.

[0144] like Figure 2As shown, the battery pack maintenance tooling also includes an electrical control box 103 mounted on the base 100. The electrical control box 103 includes an electrical control room and a storage room. The electrical control room can house control components such as controllers, while the storage room can be used to store detachable parts and commonly used tools of the battery pack maintenance tooling, such as handles 900, connecting terminals, and wrenches. Furthermore, the storage room and the electrical control room can be sealed and separated by a partition to prevent water stains, dust, and other debris from entering the electrical control room and damaging the controllers and other control components.

[0145] The terms "first" and "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units may include steps or units not listed, but rather not listed.

[0146] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
