[0029] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0030] Refer to Figure 1 As shown, the safety disassembly device for a large battery pack provided in the embodiment of the present utility model includes a base 100, a support platform 200, a fixing component 300, a boom component 400, a first driving device 500, and a second driving device 600; the fixing component 300 is installed on the support platform 200, and the fixing component 300 is used to fix the battery pack on the support platform 200; both ends of the boom component 400 are rotatably connected to the base 100 and the support platform 200 respectively; the first driving device 500 is rotatably connected to the support platform 200, and the first driving device 500 is used to drive the support platform 200 to rotate; the second driving device 600 is connected to the boom component 400, and the second driving device 600 is used to drive the boom component 400 to rotate relative to the base 100.

[0031] The boom component 400 is rotatably connected to the base 100 and the support platform 200 respectively, and the first driving device 500 can drive the support platform 200 to flip relative to the boom component 400, so that the support platform 200 can be set in a side-turn state and a horizontal state. As Figure 1 shown, when the support platform 200 is in a side-turn state, it is convenient for workers to disassemble the battery pack on the support platform 200; the second driving device 600 can drive the boom component 400 to rotate relative to the base 100, so that the second driving device 600 can adjust the height of the support platform 200. As Figure 2 shown, when the support platform 200 is in a horizontal state, the second driving device 600 can adjust the height of the support platform 200 to a lower position, so that it is not necessary to lift too high when loading the battery pack, making the loading of the battery pack more convenient.

[0032] As Figure 1 、 2 shown, when it is necessary to place the battery pack, the second driving device 600 drives the boom component 400 to rotate counterclockwise, making the end of the boom component 400 away from the base 100 closer to the base 100, so that there is a smaller angle between the boom component 400 and the base 100. At the same time, the first driving device 500 drives the support platform 200 to rotate to make it horizontally set, and the worker places the battery pack on the support platform 200, and the fixing component 300 fixes the battery pack on the support platform 200;

[0033] As Figure 1As shown, when the battery pack needs to be turned over laterally, the second driving device 600 drives the boom assembly 400 to rotate clockwise, so that the end of the boom assembly 400 away from the base 100 moves away from the base 100, making the boom assembly 400 vertically arranged. At the same time, the first driving device 500 drives the support platform 200 to rotate, so that it can be turned over laterally, facilitating the disassembly operation of the middle position or other positions of the battery pack by the staff.

[0034] Specifically, the battery pack can be a large-sized battery pack; the first driving device 500 can adopt an oil cylinder or other structures capable of driving the support platform 200 to rotate relative to the boom assembly 400; the second driving device 600 can adopt an oil cylinder or other structures capable of driving the boom assembly 400 to rotate relative to the base 100; the first driving device 500 can be one, two or more, and the second driving device 600 can be one, two or more.

[0035] Further, as Figure 1 shown, the first driving device 500 is set to two, and the two first driving devices 500 are arranged at intervals in the left-right direction of the base 100. The first driving device 500 is a first oil cylinder with a hydraulic lock. Each first oil cylinder includes a first extension rod 510 and a first cylinder block 520. The first cylinder block 520 is used to drive the first extension rod 510 to extend and retract. The two ends of the first driving device 500 are respectively rotatably connected to the base 100 and the support platform 200; by driving the support platform 200 to rotate with the two first driving devices 500, the rotation of the support platform 200 can be made smoother; the first driving device 500 is a first oil cylinder with a hydraulic lock, so that the first driving device 500 can enable the support platform 200 to stop and stay at any angular position through the hydraulic lock. Specifically, the hydraulic lock is installed on the oil cylinder pipeline. Without a control signal, the support platform 200 cannot fall back and turn over under the action of its own gravity.

[0036] During operation, when the first cylinder block 520 drives the first extension rod 510 to extend and retract, the boom assembly 400 does not move, and the support platform 200 mainly rotates around the upper end of the boom assembly 400, and the support platform 200 also rotates a certain angle around the upper end of the first extension rod 510.

[0037] Specifically, as Figure 1 、 2 shown, the positions where the first driving device 500 is connected to the base 100 and the positions where the boom assembly 400 is connected to the base 100 are both located on the rear side of the base 100. The boom assembly 400 is located behind the first driving device 500, so that when the boom assembly 400 rotates counterclockwise, the first driving device 500 can also rotate counterclockwise, enabling the support platform 200 to be lowered to a lower position, and also ensuring that the first driving device 500 can normally drive the support platform 200 to turn over laterally;

[0038] On the premise that the support platform 200 can be adjusted in height normally up and down and can be turned over normally, the positions where the first driving device 500 is connected to the base 100 and the positions where the boom assembly 400 is connected to the base 100 can be at other positions on the base 100.

[0039] Specifically, as Figure 1 shown, one end of the first cylinder body 520 away from the first extension rod 510 is rotatably connected to the base 100, and one end of the first extension rod 510 away from the first cylinder body 520 is rotatably connected to the support platform 200.

[0040] Furthermore, as Figure 1 shown, the boom assembly 400 includes a first boom 410, a second boom 420 and a connecting rod 430. The first boom 410 and the second boom 420 are connected by the connecting rod 430 and are arranged at intervals in the left - right direction of the base 100. Both ends of the first boom 410 and both ends of the second boom 420 are respectively rotatably connected to the base 100 and the support platform 200. The connecting rod 430 is provided to ensure that the first boom 410 and the second boom 420 rotate synchronously, ensuring that the support platform 200 can be lowered to a lower position.

[0041] Specifically, both ends of the first boom 410 and both ends of the second boom 420 are respectively rotatably connected to the base 100 and the support platform 200 through pin shafts. Both ends of the first boom 410 and both ends of the second boom 420 can also be rotatably connected to the base 100 and the support platform 200 through other structures.

[0042] Furthermore, as Figure 1 shown, two second driving devices 600 are provided. The two second driving devices 600 are arranged at intervals in the left - right direction of the base 100. The second driving device 600 is a second oil cylinder with a hydraulic lock. Each second oil cylinder includes a second extension rod 610 and a second cylinder body 620. The second cylinder body 620 is used to drive the second extension rod 610 to extend and retract. One end of one second oil cylinder is respectively rotatably connected to the middle part of the first boom 410 and the base 100, and one end of the other second oil cylinder is respectively rotatably connected to the middle part of the second boom 420 and the base 100; the first boom 410 and the second boom 420 are respectively driven by the two second driving devices 600 to rotate, so that the rotation of the boom assembly 400 is smoother; the second driving device 600 is a second oil cylinder with a hydraulic lock, so that the second driving device 600 can make the support platform 200 stop and stay at any height position through the hydraulic lock. Specifically, the hydraulic lock is installed on the oil cylinder pipeline. Without a control signal, the support platform 200 cannot fall back under the action of its own gravity.

[0043] Specifically, as Figure 1As shown, one end of the second cylinder block 620 away from the second extension rod 610 is rotatably connected to the front side of the base 100 through a pin shaft, and one end of the second extension rod 610 away from the second cylinder block 620 is rotatably connected to the middle part of the first moving arm 410 or the middle part of the second moving arm 420 through a pin shaft. The first moving arm 410 and the second moving arm 420 are both arranged at the rear side of the base 100 to facilitate reducing the height of the support platform 200. One end of the second cylinder block 620 away from the second extension rod 610 can also be rotatably connected to the base 100 through other structures, and one end of the second extension rod 610 away from the second cylinder block 620 can also be rotatably connected to the middle part of the first moving arm 410 or the middle part of the second moving arm 420 through other structures.

[0044] Specifically, the first driving device 500 and the second driving device 600 are electrically connected to the control device. The control of the first driving device 500 can be through the proximal button of the control device or the remote controller at the remote end. By setting the remote controller and the proximal button, the flipping of the support platform 200 can be paused at any position within the adjustable range, facilitating the operator to disassemble the battery pack in an inclined state. The control of the second driving device 600 can be through the proximal button of the control device or the remote controller at the remote end. By setting the remote controller and the proximal button, the lifting of the support platform 200 can be paused at any position within the adjustable range, facilitating the operator to disassemble the battery pack in a horizontal state.

[0045] Further, as Figure 1 、 3 shown, the support platform 200 includes a support base 210, a disassembly table 220 and a disassembly table driving device 230. The support base 210 is rotatably connected to the boom assembly 400 and rotatably connected to the first driving device 500. The disassembly table 220 is movably installed on the support base 210 in the front-back direction. The fixing component 300 is installed on the disassembly table 220. The support base 210 has a chute 211, and the disassembly table 220 has a slide rail 221 slidably connected to the chute 211. The disassembly table driving device 230 is installed on the support base 210, and the disassembly table driving device 230 is used to drive the disassembly table 220 to move back and forth relative to the support base 210.

[0046] Enable the disassembly table 220 to move back and forth to adjust the height when the battery pack is turned over, so that the disassembly device can adapt to workers of different heights. And enable the safety disassembly device to adjust both the up-down height and the side-turning angle of the disassembly table 220, as well as the height when the battery pack is turned over.

[0047] Specifically, the support base 210 and the disassembly table 220 are welded by steel plates. The upper surface of the disassembly table 220 is paved with a PP board as the surface layer for insulation treatment, which can effectively isolate the battery pack from the disassembly table 220. When the battery pack leaks electricity, it can prevent the electricity from being conducted to the disassembly table 220. The disassembly table 220 can conduct the leaked current to the ground through a special grounding wire to prevent electric shock accidents.

[0048] Specifically, the boom assembly 400 is rotatably connected to the bottom of the rear side of the support base 210, and the first driving device 500 is rotatably connected to the bottom of the middle of the support base 210. When ensuring that the support base 210 can drive the disassembly table 200 to be horizontally set and inclined, the boom assembly 400 and the first driving device 500 can also be arranged at other positions at the bottom of the base 100.

[0049] Specifically, the disassembly table driving device 230 is an oil cylinder with a hydraulic lock, so that the disassembly table 220 can stop and maintain at any height position through the hydraulic lock.

[0050] Further, as Figure 2 、 4 shown, the fixing assembly 300 includes a support plate 310, a clamping mechanism 320 and a pressing mechanism 330. The support plate 310 is arranged at the rear end of the disassembly table 220. The clamping mechanism 320 and the pressing mechanism 330 are both installed on the disassembly table 220. The clamping mechanism 320 is located in front of the support plate 310. The clamping mechanism 320 can clamp the battery pack between the clamping mechanism 320 and the support plate 310, and the pressing mechanism 330 can press the battery pack between the pressing mechanism 330 and the disassembly table 220, so as to fix the battery pack on the disassembly table 220 through the clamping mechanism 320 and the pressing mechanism 330.

[0051] Specifically, the clamping mechanism 320 can adopt a cylinder or other devices that can clamp the battery pack on the support plate 310; the pressing mechanism 330 can adopt a cylinder or other devices that can press the battery pack on the disassembly table 220.

[0052] Further, as Figure 2 、 4As shown, the clamping mechanism 320 includes a first clamping block 321 and a clamping driving device 322. The clamping driving device 322 is installed on the disassembly table 220. The first clamping block 321 is installed on the clamping driving device 322 and is located in front of the support plate 310. The clamping driving device 322 is used to drive the first clamping block 321 to move back and forth. The battery pack is clamped between the first clamping block 321 and the support plate 310. The pressing mechanism 330 includes a second clamping block 331 and a pressing driving device 332. The pressing driving device 332 is fixedly connected to the first clamping block 321. The second clamping block 331 is installed on the pressing driving device 332. The pressing driving device 332 is used to drive the second clamping block 331 to move up and down. The battery pack is pressed between the second clamping block 331 and the disassembly table 220.

[0053] The battery pack can be fixed between the first clamping block 321 and the support plate 310 by the first clamping block 321 to achieve fixation in the front-back direction, and the battery pack can be fixed between the second clamping block 331 and the support platform 200 by the second clamping block 331 to achieve fixation in the up-down direction; since the first clamping block 321 can move back and forth and the second clamping block 331 can move up and down, the disassembly device can be applicable to battery packs of different sizes; since there are no other structures on the left and right sides of the support platform 200, it is convenient for the staff to disassemble the side of the battery pack.

[0054] When fixing the battery pack, the clamping driving device 322 drives the first clamping block 321 to move forward, the second clamping block 331 moves forward together with the first clamping block 321, the pressing driving device 332 drives the second clamping block 331 to move upward, so that the height of the second clamping block 331 is higher than the thickness of the battery pack. Then the battery pack is placed on the disassembly table 220 and is located between the first clamping block 321 and the support plate 310. The clamping driving device 322 drives the first clamping block 321 to move backward to fix the battery pack between the first clamping block 321 and the support plate 310. Then the pressing driving device 332 drives the second clamping block 331 to move downward to fix the battery pack between the second clamping block 331 and the disassembly table 220.

[0055] Specifically, the clamping driving device 322 and the pressing driving device 332 can adopt an oil cylinder or other structures that can drive the clamping block to move linearly; one, two or more than two clamping mechanisms 320 and pressing mechanisms 330 can be provided.

[0056] Further, as Figure 1 、 2As shown, there are two clamping mechanisms 320 and two pressing mechanisms 330. The two clamping mechanisms 320 are arranged at intervals in the left - right direction of the disassembly table 220 and are installed on the disassembly table 220. The two pressing mechanisms 330 are respectively installed on the two clamping mechanisms 320; the battery pack is fixed by the two clamping mechanisms 320 and the two pressing mechanisms 330 to clamp the battery pack more firmly, and the two clamping mechanisms 320 and the two pressing mechanisms 330 are both independently controlled. When clamping a battery pack with an uneven and irregular edge, the two clamping mechanisms 320 and the two pressing mechanisms 330 can act independently through the control system to clamp, making it easier to clamp the battery pack.

[0057] Furthermore, as Figure 2 , 5 shown, it further includes an induction component 700. The induction component 700 includes a proximity switch 710, a collision - prevention rod 720, a hinge support 730, a moving rod 740, and an elastic member 750. Both the hinge support 730 and the proximity switch 710 are installed at the bottom of the rear side of the disassembly table 220. The moving rod 740 is installed on the hinge support 730 so as to be movable back and forth relative to the disassembly table 220. One end of the moving rod 740 is rotatably connected to the collision - prevention rod 720, and one end of the collision - prevention rod 720 is rotatably connected to the bottom of the rear side of the disassembly table 220. The elastic member 750 is provided between the moving rod 740 and the hinge support 730;

[0058] The moving rod 740 can move between a first position and a second position; when the moving rod 740 is in the first position, the other end of the moving rod 740 is within the detection area of the proximity switch 710; when the moving rod 740 is in the second position, the other end of the moving rod 740 is outside the detection area of the proximity switch 710;

[0059] When the collision - prevention rod 720 causes the moving rod 740 to deviate from the second position, the elastic member 750 exerts a force on the collision - prevention rod 720 to move it towards the second position. Among them, the direction of the force is towards the second position, and in the absence of other forces, the collision - prevention rod 720 can move to the second position.

[0060] By providing the collision - prevention rod 720 and the proximity switch 710, when the disassembly table 220 overturns at a large angle and the collision - prevention rod 720 touches the ground, the proximity switch 710 can feedback the information that the disassembly table 220 is about to touch the ground, improving the safety of the disassembly device.

[0061] Specifically, the elastic member 750 is a spring or other elastic member that can elastically recover.

[0062] Further, the proximity switch 710 can be electrically connected to the alarm device, and then alarm through the alarm device; alternatively, the proximity switch 710 is electrically connected to the control device, and the control device is electrically connected to the first driving device 500. Then, the control device can control the opening and closing of the first driving device 500 according to the information fed back by the proximity switch 710. Thus, when the disassembly table 220 is about to touch the ground, the control device closes the first driving device 500; or the proximity switch 710 is electrically connected to the control device, and the control device is used to alarm and control the opening and closing of the first driving device 500.

[0063] Taking the example that the control device only controls the opening and closing of the first driving device 500:

[0064] As Figure 1 、 5 shown, during operation, when the first driving device 500 drives the support base 210 to rotate relative to the upper end of the boom assembly 400, it drives the disassembly table 220 to roll over. When the other end of the anti-collision bar 720 touches the ground during the rollover, the anti-collision bar 720 compresses the spring under the action of the ground and the upper end of the anti-collision bar 720 rotates around the bottom of the rear side of the disassembly table 220. The anti-collision bar 720 drives the moving rod 740 to move while rotating. Among them, since the moving rod 740 can only move along the front-back direction of the disassembly table 220 and the moving rod 740 is rotatably connected to the anti-collision bar 720, the anti-collision bar 720 can drive the moving rod 740 to move back and forth. When the other end of the moving rod 740 moves into the detection area of the proximity switch 710 (i.e., moves from the second position to the first position), the proximity switch 710 knows that the anti-collision bar 720 has touched the ground. The proximity switch 710 feeds back the information to the control device, and the control device controls the first driving device 500 to stop rolling over; when the rollover of the support platform 200 does not contact the ground, the spring resumes, causing the moving rod 740 to move from the first position to the second position and keeping the moving rod 740 in the second position all the time, that is, the anti-collision bar 720 resumes its original position, and the first driving device 500 can work normally.

[0065] Specifically, the upper end of the anti-collision bar 720 is connected to the bottom of the rear side of the disassembly table 220, one end of the moving rod 740 is rotatably connected to the middle of the anti-collision bar 720, and the proximity switch 710 is located to the left of the moving rod 740.

[0066] Specifically, the hinge support 730 has a through hole, and the moving rod 740 is movably arranged in the through hole relative to the disassembly table 220 in the front-back direction, so that the moving rod 740 is slidably connected to the hinge support 730.

[0067] Further, as Figure 1As shown, the second driving device 600 can lock the angle of the boom assembly 400 relative to the base 100. When the boom assembly 400 does not rotate, the support platform 200 can roll over relative to the boom assembly 400 to facilitate the rotation of the support platform 200.

[0068] Specifically, the second driving device 600 can adopt an oil cylinder with a hydraulic lock or other devices that can lock the angle of the boom assembly 400 relative to the base 100.

[0069] Furthermore, as Figure 6 shown, a power device 800 is provided on one side of the base 100. The power device includes an oil tank 810, a pipeline 820, a hydraulic oil pump, and a driving motor. The oil tank 810 is connected to the disassembly table driving device 230, the first driving device 500, and the second driving device 600 through the pipeline 820 respectively. A hydraulic oil pump is provided on the pipeline 820, and the driving motor is used to drive the hydraulic oil pump to open and close. The power device provides power for the disassembly table driving device 230, the first driving device 500, and the second driving device 600.

[0070] Furthermore, the base 100 is welded by steel plates, and the base 100 is fixed to the ground through anchor bolts.

[0071] Furthermore, a fence 110, a grating 120, and an audible and visual alarm are provided on the outer periphery of the base 100. When the grating 120 detects the presence of personnel in the equipment activity area in the overturned state of the disassembly table 220, it sends a signal to the control device to cut off actions such as flipping, clamping, and pressing, and prevent the tipping accident of the battery pack. The fence 120 encloses the base 100 to achieve mechanical isolation and prevent personnel from entering. After the proximity switch 710 and the grating 120 are triggered, the audible and visual alarm installed on the control device emits an alarm signal to remind personnel to pay attention to safety and prevent workers from entering the fence 110.

[0072] When the utility model works:

[0073] 1. As Figure 1 、 2 shown, the first cylinder block 520 makes the first extension rod 510 contract and the second cylinder block 620 makes the second extension rod 610 contract, so that the support seat 210 is horizontally arranged and lowered to the lowest position;

[0074] 2. As Figure 2As shown, the clamping drive device 322 drives the first clamping block 321 to move forward, and the second clamping block 331 follows the first clamping block 321 to move forward together. The pressing drive device 332 drives the second clamping block 331 to move upward, so that the height of the second clamping block 331 is higher than the thickness of the battery pack. Then, the battery pack is placed on the disassembly table 220 and located between the first clamping block 321 and the support plate 310. The clamping drive device 322 drives the first clamping block 321 to move backward, fixing the battery pack between the first clamping block 321 and the support plate 310. Then, the pressing drive device 332 drives the second clamping block 331 to move downward, fixing the battery pack between the second clamping block 331 and the disassembly table 220;

[0075] 3. As Figure 1 As shown, the second cylinder block 620 extends the second extension rod 610, driving both the first moving arm 410 and the second moving arm 420 to rotate clockwise relative to the base 100. At the same time, the first drive device 500 synchronously rotates clockwise relative to the base 100, thereby raising the height of the support base 210. Then, the first cylinder block 520 extends the first extension rod 510, driving the support base 210 to flip relative to the first moving arm 410 and the second moving arm 420, causing the battery pack on the disassembly table 220 to turn over, and the staff disassembles the turned-over battery pack.

[0076] Beneficial effects:

[0077] 1. The disassembly device of the present utility model is provided with a moving arm assembly 400, a first drive device 500, and a second drive device 600. The moving arm assembly 400 is respectively rotatably connected to the base 100 and the support platform 200. The first drive device 500 can drive the support platform 200 to flip relative to the moving arm assembly 400, so that the support platform 200 can be set to turn over and horizontally set. As Figure 1 shown, when the support platform 200 is in a turned-over state, it is convenient for the staff to perform disassembly operations on the battery pack on the support platform 200; the second drive device 600 can drive the moving arm assembly 400 to rotate relative to the base 100, so that the second drive device 600 can adjust the height of the support platform 200. As Figure 2As shown, when the support platform 200 is in a horizontal state, the second driving device 600 can adjust the height of the support platform 200 to a lower position, so that there is no need to lift too high when loading the battery pack, making the loading of the battery pack more convenient; and by making the support platform 200 include a support base 210, a disassembly table 220 and a disassembly table driving device 230, the disassembly table driving device 230 can drive the disassembly table 220 to move back and forth relative to the support base 210 to adjust the height when the battery pack is overturned, so that the disassembly device can adapt to workers of different heights, and the safety disassembly device can adjust both the up and down height of the disassembly table 220, the side turnover angle of the battery pack, and the height when the battery pack is overturned; and by arranging a first clamping block 321 that can move back and forth and a second clamping block 331 that can move up and down on the disassembly table 220, the first clamping block 320 can move back and forth so that the first clamping block 320 can clamp battery packs of different lengths or widths, and the second clamping block 331 can move up and down so that the second clamping block 331 can clamp battery packs of different heights, enabling the disassembly device to be applicable to battery packs of different sizes.

[0078] 2. The second driving device 600 of the disassembly device of the present utility model adopts an oil cylinder with a hydraulic lock, and the hydraulic lock is installed on the oil cylinder pipeline. In the absence of a control signal, the support platform 200 cannot lower its height under the action of its own gravity, so that the second driving device 600 can make the support platform 200 stop and remain at any horizontal height position through the hydraulic lock, and can flexibly adjust the horizontal height, facilitating disassembly operations on the battery pack at different heights by operators of different heights; the first driving device 500 of the disassembly device of the present utility model adopts an oil cylinder with a hydraulic lock, and the hydraulic lock is installed on the oil cylinder pipeline. In the absence of a control signal, the support platform 200 cannot rotate under the action of its own gravity. Furthermore, the first driving device 500 can make the support platform 200 stop and remain at any angle position through the hydraulic lock, and can flexibly adjust the side turnover angle, facilitating disassembly operations on the battery pack in the side turnover state by operators.

[0079] 3. The disassembly device of the present utility model is provided with a control device, a collision prevention rod 720, a moving rod 740, a proximity switch 710 and an audible and visual alarm. When the support platform 200 is turned over at a large angle, causing the collision prevention rod 720 to touch the ground, the collision prevention rod 720 moves the moving rod 740 into the detection range of the proximity switch 710. Furthermore, the proximity switch 710 can feedback the information that the collision prevention rod 720 touches the ground to the control device, and the control device controls the first driving device 500 to stop turning over and controls the audible and visual alarm to give an alarm, improving the safety of the disassembly device.
