DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0031] like Figure 1 As shown, an embodiment of the utility model provides a battery maintenance platform, including a lifting drive 100, a locking mechanism 200, a storage box 300 with a storage space 310 and a storage table 400 for placing batteries; the storage table 400 is installed on the lifting drive 100, and the lifting drive 100 is installed in the storage box 300 and is used to drive the storage table 400 to rise and fall in the storage space 310; the locking mechanism 200 is installed in the storage box 300 and is used to lock the storage table 400 at the current position when the storage table 400 completes the lifting.

[0032] In this embodiment, the battery maintenance platform can be in a storage mode, at which time the storage table 400 can be driven by the lifting drive 100 to rise to a certain position (for example, flush with or slightly higher than the top surface of the accommodating space 310), and the locking mechanism 200 can lock the storage table 400 at the current position when the storage table 400 reaches the above position, so as to facilitate disassembly or testing of the batteries placed on the storage table 400.

[0033] The storage space 310 in the storage box 300 may store a fire extinguishing medium (e.g., water, aerosol, or perfluorohexanone, etc.) in advance. During the process of disassembling or testing the batteries on the storage table 400, the batteries may burn or explode. The battery maintenance platform may also be in a fire extinguishing mode. At this time, if the batteries on the storage table 400 burn or explode, the locking mechanism 200 will release the lock on the storage table 400, and lower the batteries on the storage table 400 into the storage space 310 through the lifting drive 100, so that the batteries on the storage table 400 can be immersed in the fire extinguishing medium in the storage space 310 for a long time to extinguish the fire.

[0034] It can be understood that the lifting drive 100 can be located inside or outside the storage space 310, as long as it can drive the storage table 400 to rise and fall inside the storage space 310. The lifting drive 100 can be a drive member that can directly move in a straight line, such as a cylinder or a hydraulic cylinder, or a drive member that converts rotary motion into linear motion by a motor in conjunction with a gear rack or a worm gear. The locking mechanism 200 can be connected to the storage table 400 and directly lock the movement of the storage table 400 relative to the storage box 300; the locking mechanism 200 can also be connected to the lifting drive 100, and limit the movement of the storage table 400 relative to the storage box 300 by locking the lifting drive 100. The storage box 300 can be filled with sealing material to prevent the fire extinguishing medium in the storage space 310 from leaking. It can be understood that the storage box 300 has an opening; the storage table 400 is installed in the storage space 310 through the opening, and the projection of the storage table 400 in the opening direction of the storage box 300 does not intersect with the opening, so that the storage table 400 can enter and exit the storage space 310 in the storage box 300 through the opening.

[0035] In the above-mentioned embodiment of the utility model, the storage table 400 is driven to rise and fall in the accommodating space 310 by the lifting drive 100, and the storage table 400 is locked at the current position by the locking mechanism 200 when the storage table 400 completes the lifting, so that the lifting drive 100 does not need to always apply a supporting force to the storage table 400, thereby improving the durability of the lifting drive 100 and saving the energy consumption of the lifting drive 100. In addition, when the battery on the storage table 400 catches fire, the fire extinguishing medium can be directly stored in advance in the storage space 310 in the storage box 300, and when it is necessary to spray the battery placed on the storage table 400 with the fire extinguishing medium, the fire extinguishing medium after spraying can flow into the storage space 310; at the same time, after the locking mechanism 200 releases the lock on the storage table 400, the battery on the storage table 400 can be lowered into the storage space 310 in the storage box 300 through the lifting drive 100, so that the battery on the storage table 400 is immersed in the fire extinguishing medium in the storage space 310, thereby improving the fire extinguishing effect.

[0036] like Figure 1 and Figure 2As shown, in one embodiment, the locking mechanism 200 includes a clamping cylinder 210 and a connecting shaft 220 parallel to the lifting direction of the storage platform 400; one end of the connecting shaft 220 is connected to the storage platform 400, and the other end of the connecting shaft 220 is connected to the clamping cylinder 210; the clamping cylinder 210 is installed on the storage box 300 and is used to clamp the connecting shaft 220 when the storage platform 400 is lifted and lowered, so that the storage platform 400 is locked in the current position. It can be understood that the connection method between the connecting shaft 220 and the storage platform 400 includes but is not limited to one or more of the methods such as plug-in, bolt, buckle, rivet, welding or integrated molding, as long as a stable connection can be formed between the connecting shaft 220 and the storage platform 400. The clamping cylinder 210 is provided with a clamping hole, and the other end of the connecting shaft 220 is inserted into the clamping hole; when the clamping cylinder 210 is in the unclamping state, the connecting shaft 220 is slidably connected with the clamping cylinder 210; when the clamping cylinder 210 is in the clamping state, the clamping cylinder 210 clamps the connecting shaft 220, so that a fixed connection is formed between the clamping cylinder 210 and the connecting shaft 220, and at this time, the locking mechanism 200 locks the storage platform 400 in the current position. The clamping cylinder 210 may be provided with a control valve, and when the control valve is powered on, the clamping cylinder 210 is in the unclamping state, and when the control valve is powered off, the clamping cylinder 210 is in the clamping state, so as to prevent the clamping cylinder 210 from releasing the clamping of the connecting shaft 220 in the event of an accidental power failure, thereby preventing the storage platform 400 from falling due to the clamping cylinder 210 releasing the clamping of the connecting shaft 220.

[0037] like Figures 1 to 4As shown, in one embodiment, the storage box 300 includes a box body 320 with a storage space 310, and a mounting plate 330 disposed in the storage space 310; a guide hole 331 is disposed on the mounting plate 330; the clamping cylinder 210 is mounted on the mounting plate 330; the end of the connecting shaft 220 away from the storage platform 400 passes through the guide hole 331 to connect to the clamping cylinder 210; the fixed end of the lifting drive member 100 is mounted on the mounting plate 330, and the output end of the lifting drive member 100 is connected to the storage platform 400. It can be understood that the connecting shaft 220 is slidably connected to the guide hole 331, and the guiding direction of the guide hole 331 for the connecting shaft 220 is the lifting direction of the storage platform 400 in the storage space 310. The clamping hole and the guide hole 331 are coaxially arranged, so that the connecting shaft 220 can pass through the guide hole 331 and the clamping hole at the same time, and can move in the clamping hole 331 in the guiding direction corresponding to the guide hole 331. A flange may be provided at the fixed end of the lifting drive 100, and the flange may be mounted on the mounting plate 330 by bolts, thereby finally realizing a fixed connection between the fixed end of the lifting drive 100 and the mounting plate 330. The box 320 may be made of steel. A movable universal caster may be installed at the bottom of the box 320 to facilitate movement of the box 320. The connection method between the clamping cylinder 210 and the mounting plate 330 includes, but is not limited to, one or more of bolts, snaps, rivets or welding, as long as a stable connection can be formed between the clamping cylinder 210 and the mounting plate 330. The number of connecting shafts 220 may be set as required, for example, set to 4, and the 4 connecting shafts 220 may be set around the storage table 400, thereby forming a stable guide for the storage table 400. The clamping cylinder 210 can be mounted on the side of the mounting plate 330 facing the storage platform 400, or the clamping cylinder 210 can be mounted on the side of the mounting plate 330 facing away from the storage platform 400, as long as the connecting shaft 220 can be connected to the clamping cylinder 210. The fixed end of the lifting drive 100 can be mounted on the side of the mounting plate 330 facing the storage platform 400, or the fixed end of the lifting drive 100 can be mounted on the side of the mounting plate 330 facing away from the storage platform 400, as long as the lifting drive 100 can drive the storage platform 400 to rise and fall in the storage space 310.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the battery maintenance platform further includes a sliding protection member 800 disposed in the guide hole 331; the guide rod is slidably connected to the guide hole 331 through the sliding protection member 800. It can be understood that the sliding protection member 800 is used to reduce the wear when the guide rod slides with the guide hole 331. The sliding protection member 800 includes but is not limited to a sliding bushing or a linear bearing.

[0039] like Figures 1 to 4As shown, in one embodiment, the storage box 300 further includes at least one supporting leg 340; one end of the supporting leg 340 is mounted on the bottom surface of the storage space 310, and the other end of the supporting leg 340 is connected to the end surface of the mounting plate 330 away from the storage table 400; a supporting space 350 is formed between the bottom surface of the storage space 310 and the mounting plate 330; the clamping cylinder 210 is located in the supporting space 350; a through hole 332 is provided on the mounting plate 330; the fixed end of the lifting drive member 100 is located in the supporting space 350; and the output end of the lifting drive member 100 is connected to the storage table 400 through the through hole 332. It can be understood that the connection method between the supporting leg 340 and the bottom surface of the storage space 310 includes but is not limited to one or more of bolts, buckles, rivets or welding, as long as the supporting leg 340 can be stably mounted on the bottom surface of the storage space 310. The supporting space 350 is located in the storage space 310 and on the side of the mounting plate 330 away from the storage table 400. The fixed ends of the clamping cylinder 210 and the lifting drive member 100 are both arranged in the supporting space 350, that is, the fixed ends of the clamping cylinder 210 and the lifting drive member 100 are both located on the side of the mounting plate 330 away from the storage table 400, so that the clamping cylinder 210 or the lifting drive member 100 will not interfere with the descent of the storage table 400, and the storage table 400 can be lowered to a position abutting against the mounting plate 330, and the mounting plate 330 can form a stable support for the storage table 400.

[0040] like Figure 1 As shown, in one embodiment, the battery maintenance platform further includes a floating connector 500; one end of the floating connector 500 is connected to the storage platform 400, and the other end of the floating connector 500 is connected to the output end of the lifting drive 100. It can be understood that in this embodiment, the output end of the lifting drive 100 is connected to the storage platform 400 via the floating connector 500. The floating connector 500 can be used to compensate for the angle deviation that may exist between the output end of the lifting drive 100 and the storage platform 400, so as to avoid the lifting drive 100 from being stuck due to the above-mentioned angle deviation. Figure 5As shown, in one embodiment, the floating connection member 500 may include a floating connection seat 510 connected to the storage platform 400, and a floating connection head 520 connected to the output end of the lifting drive member 100. The floating connection seat 510 and the floating connection head 520 are floatingly connected to each other, thereby compensating for the angle deviation between the output end of the lifting drive member 100 and the storage platform 400. The connection method of the floating connection seat 510 and the storage platform 400 includes, but is not limited to, one or more of bolts, buckles, rivets or welding, as long as a stable connection can be formed between the floating connection seat 510 and the storage platform 400. The connection method of the floating connection head 520 and the lifting drive member 100 includes, but is not limited to, one or more of bolts, buckles, rivets or welding, as long as a stable connection can be formed between the floating connection head 520 and the output end of the lifting drive member 100.

[0041] like Figure 1 As shown, in one embodiment, the battery maintenance platform further includes a spray mechanism 600 for spraying the batteries on the storage platform 400. It can be understood that the spray mechanism 600 can spray a fire extinguishing medium. The spray mechanism 600 is used to spray the batteries to cool down or extinguish the fire when the batteries on the storage platform 400 are in thermal runaway. The spray mechanism 600 can be installed on the storage box 300 or not connected to the storage box 300, as long as it can spray the batteries on the storage platform 400.

[0042] like Figure 6 As shown, in one embodiment, the spray mechanism 600 includes a delivery pipeline 610 for inputting a fire extinguishing medium, and a mist spray head 620 connected to the delivery pipeline 610; the mist spray head 620 is arranged opposite to the storage table 400. It can be understood that the delivery pipeline 610 can be installed on the outer wall of the storage box 300, one end of the delivery pipeline 610 is connected to the external fire extinguishing medium, and the other end of the delivery pipeline 610 is connected to the mist spray head 620, and the fire extinguishing medium is sprayed onto the battery on the storage table 400 through the mist spray head 620. The mist spray head 620 can make the fire extinguishing medium evenly dispersed, so that the area covered by the fire extinguishing medium is larger, and the cooling or fire extinguishing effect on the battery is better. In one embodiment, the spray mechanism 600 also includes a mounting bracket 630 connected to the delivery pipeline 610, and the delivery pipeline 610 is installed on the outer wall of the storage box 300 through the mounting bracket 630.

[0043] like Figure 2As shown, in one embodiment, a receiving groove 410 for receiving battery disassembly materials is provided on the storage platform 400. It can be understood that the receiving groove 410 is used to receive battery disassembly materials (such as electrolyte or battery parts, etc.) generated by the battery when the battery on the storage platform 400 is disassembled or tested, so as to prevent the battery disassembly materials from falling into the storage box 300. Furthermore, the receiving groove 410 can also guide the heat (including high-temperature gas, etc.) ejected by the battery when the battery on the storage platform 400 is in thermal runaway, so as to prevent the heat from splashing out of the storage platform 400. Furthermore, the receiving groove 410 is arranged around the storage platform 400, so that the receiving groove 410 can surround the battery on the storage platform 400, so as to prevent the battery disassembly materials from falling into the storage box 300, and at the same time prevent the heat from splashing out of the storage platform 400.

[0044] like Figure 2 As shown, in one embodiment, a drainage hole 440 for draining the fire extinguishing medium is provided on the storage platform 400. It can be understood that the drainage hole 440 can drain the fire extinguishing medium when the storage platform 400 is raised or lowered in the storage space 310, that is, when the storage platform 400 descends into the storage space 310, the fire extinguishing medium located on the side of the storage platform 400 away from the battery in the storage space 310 flows into the side of the storage platform 400 facing the battery, so that the battery can be immersed in the fire extinguishing medium; when the storage platform 400 rises, the fire extinguishing medium located on the side of the storage platform 400 facing the battery in the storage space 310 flows into the side of the storage platform 400 away from the battery, thereby preventing the fire extinguishing medium from escaping from the storage space 310.

[0045] In one embodiment, the battery maintenance platform further includes a temperature sensor (not shown) disposed on the storage platform 400 and used to detect the temperature of the battery on the storage platform 400. It can be understood that the battery maintenance platform may also include Figure 7 The controller 700 shown is connected to the temperature sensor, the locking mechanism 200 and the lifting drive 100 respectively. The battery maintenance platform can activate the above-mentioned fire extinguishing mode through the temperature sensor, that is, after the temperature sensor detects that the temperature of the battery on the storage table 400 exceeds the preset value (that is, the battery may burn or explode), the locking mechanism 200 is controlled to release the lock of the storage table 400, and the lifting drive 100 is controlled to lower the battery on the storage table 400 into the storage space 310, so that the battery on the storage table 400 can be immersed in the fire extinguishing medium in the storage space 310 for a long time. The battery maintenance platform can also activate the above-mentioned fire extinguishing mode when the user needs it. In one embodiment, the controller 700 is also connected to the spray mechanism 600. After detecting that the battery on the storage table 400 burns or explodes, the spray mechanism 600 can be controlled to spray the battery on the storage table 400.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment, the storage platform 400 includes a storage plate 420 connected to the lifting drive member 100, and a reinforcing rib 430 disposed on one side of the storage plate 420 facing the lifting drive member 100. It can be understood that the reinforcing rib 430 can strengthen the support strength of the storage plate 420, so that a heavy battery can be placed on the storage plate 420 to prevent the battery and the lifting drive member 100 from forming a torsion on the storage plate 420 and causing the storage plate 420 to be deformed or damaged. In one embodiment, an insulating pad is laid on the surface of the storage plate 420 to prevent the battery placed on the storage plate 420 from contacting the storage plate 420 and causing a short circuit.

[0047] The above are only embodiments of the battery maintenance platform of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
