Description

Technical Field

[0001] This utility model relates to the technical field of power battery handling, and more specifically, to a power battery pickup device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, higher requirements have been placed on the safety and automation levels of the production and assembly of power batteries. In actual production, especially on power battery assembly lines, when a power battery falls abnormally, it is necessary to handle the fallen battery as soon as possible to prevent dangerous situations such as short circuits, electrolyte leaks, or even thermal runaway caused by the fall, which could generate jets of gas or liquid and cause safety accidents such as burns to personnel.

[0003] However, due to the large weight and volume of individual power battery cells (reaching up to 30kg, typically exceeding 60cm in length and 20cm in width), manual handling is extremely difficult once a battery falls. This is because the casing of most power batteries is made of smooth aluminum, leaving almost no gap between the bottom of the battery and the ground. Operators struggle to find effective leverage points on the bottom and sides to move the battery. Furthermore, when a fallen battery leaks, the current initial treatment involves covering the battery surface with hydrogel. However, this makes the battery even more difficult to move, requiring operators to spend significantly more time safely transporting the leaking battery to its designated location. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as difficulty in handling power batteries when they are abnormally dropped, high operational risks, and low processing efficiency. This invention provides a power battery picking device that can quickly move abnormally dropped power batteries and is simple and convenient to operate.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A power battery pickup device is provided, including a handheld frame and a first clamp, a second clamp, a first hook and a second hook mounted on the handheld frame; The first hook, the first clamp, the second clamp, and the second hook are sequentially arranged on the handheld frame. The first clamp can be fixed to the handheld frame, and the second clamp, the first hook, and the second hook are all slidably connected to the handheld frame. The first clamp and the second clamp are used to clamp the opposite sides of the power battery respectively; the first hook and the second hook are both provided with a lifting area to support the power battery.

[0006] The handheld bracket includes two long rods, which are fixedly connected by connecting plates welded to their respective ends. A first hook, a first clamp, a second hook, and a second clamp can all slide on the two long rods. Both the first and second hooks have elongated holes through which the handheld bracket can pass. The handheld bracket can slide along the axis of these elongated holes, thereby changing the vertical position of the hooks and allowing them to move downwards on the handheld bracket as a whole until they contact the bottom surface of the power battery.

[0007] When the power battery pickup device of this utility model is in operation, firstly, two operators hold the two ends of the handle and cover the fallen power battery with the protective cover, at which point the power battery is located between the first clamp and the second clamp. Then, the two operators move the handle so that the first clamp abuts against the end face of the power battery. Then, the operator closer to the second clamp drives the second clamp towards the power battery until the second clamp also abuts against the end face of the power battery. After the second clamp also abuts against the end face of the power battery, the operator closer to the first clamp presses down on the handle. At this time, the handle can lift one side of the second clamp with the first hook as a support point. When one side of the second clamp on the handle is lifted, the power battery clamped between the first clamp and the second clamp can be lifted. To ensure that the clamp can smoothly lift the power battery, when the clamp abuts against the end face of the power battery, the height of the contact surface between the clamp and the power battery in the vertical direction is greater than 50% of the height of the power battery. After the power battery is tilted up, the operator on the side of the second clamp pushes the second hook to slide on the handheld bracket until the second hook abuts against the bottom surface of the power battery, i.e., the second hook extends into the bottom of the power battery. After the second hook extends into the bottom of the power battery, the operator near the first clamp slowly releases the handheld bracket upwards until the handheld bracket returns to its original position, and the bottom surface of the power battery returns to its original position. Then, the operator near the second clamp presses the handheld bracket down, and the handheld bracket uses the second hook as a fulcrum to tilt the first clamp up. The operator near the first clamp pushes the first hook to slide on the handheld bracket until the first hook abuts against the bottom surface of the power battery. After the first hook abuts against the bottom surface of the power battery, the operator near the second clamp slowly releases the handheld bracket upwards, and the handheld bracket returns to its original position. At this time, the first hook and the second hook respectively support the opposite sides of the bottom surface of the power battery, and the operator can lift the handheld bracket to move the power battery to the designated position.

[0008] The power battery picking device of this invention can easily and quickly move abnormally dropped power batteries to a designated location, which can significantly save manpower and emergency response time, improve production efficiency, quickly restore on-site operations, shorten equipment downtime, and avoid production capacity loss caused by abnormal events.

[0009] Furthermore, the first hook includes a first sliding part and a first lifting part connected in sequence. The first sliding part and the first lifting part are L-shaped. The first sliding part is slidably connected to the hand holder. The first lifting part can slide to abut against the bottom surface of the power battery. The second hook includes a second sliding part and a second lifting part connected in sequence. The second sliding part and the second lifting part are L-shaped. The second sliding part is slidably connected to the hand holder. The second lifting part can slide to abut against the bottom surface of the power battery.

[0010] The first and second hooks have the same structure, both including a sliding part and a lifting part, which are perpendicular to each other, allowing the lifting part to easily extend into the bottom of the raised power battery and lift it up. The lifting part can be hollowed out in the middle to further reduce the weight of the device.

[0011] Furthermore, a first rounded corner is provided at the connection between the first sliding part and the first lifting part; a second rounded corner is provided at the connection between the second sliding part and the second lifting part. When the handheld frame is tilted up, the connection between the sliding part and the lifting part serves as a fulcrum, and the rounded corner at the connection between the sliding part and the lifting part makes it easier for the operator to tilt the handheld frame up.

[0012] Furthermore, in the vertical direction, the center planes of the first hook, the first clamp, the second clamp, and the second hook coincide. That is, the first clamp is located in the middle of the first hook, and the second clamp is located in the middle of the second hook, so that the force applied to the battery when the clamps lift the battery can more easily lift the battery.

[0013] Furthermore, the first hook is provided with a first push rod, which is installed on the side of the first hook away from the first clamp; The second hook is provided with a second push rod, which is installed on the two sides of the second hook away from the second clamp.

[0014] When the operator needs to drive the hook to slide on the handheld frame, the hook can be driven to slide on the handheld frame by pushing the push rod, which makes it easier for the operator to operate.

[0015] Furthermore, a first slot is provided on the side of the first clamp near the first hook, the end of the first push rod passes through the first hook and is rotatably connected to the first hook, and a first hook is fixedly installed on the end of the first push rod, and the first push rod can be rotated to engage with the first slot. The second clamp has a second slot on each side near the second hook. The end of the second push rod passes through the second hook and is rotatably connected to the second hook. A second hook is fixedly installed on the end of the second push rod. The second push rod can be rotated until the second hook engages with the second slot.

[0016] The first hook can be threadedly connected to the first push rod; the second hook can be threadedly connected to the second push rod.

[0017] Once the hook abuts against the bottom of the power battery, rotating the push rod engages the hook with the slot, securing the clamp and hook together. The hook and slot design ensures relative fixation between the clamp and hook, allowing them to move synchronously on the handheld frame. When moving the power battery, only one of the clamps or hook needs to be controlled to prevent slippage on the handheld frame, making it easier for the operator. The threaded connection between the hook and push rod not only allows the push rod to rotate on the hook but also prevents relative slippage between the hook and push rod.

[0018] Furthermore, the first push rod has a first curved portion at the end away from the first hook, and the bending direction of the first curved portion is the same as the direction of the first hook; The second push rod has a second curved portion at both ends away from the second hook, and the bending direction of the second curved portion is the same as the direction of the second hook.

[0019] The operator can hold the curved part to rotate the push rod, making it easier for the operator to rotate the push rod. Furthermore, the curved part is in the same direction as the hook, and the operator can determine whether the hook is engaged with the slot by observing the direction of rotation of the push rod.

[0020] Furthermore, a third push rod is fixedly mounted on the second clamp, and the third push rod is mounted on the side of the second clamp away from the first clamp. The third push rod makes it easier for the operator to slide the second clamp on the handheld device.

[0021] Furthermore, it also includes a side clamp for holding the power battery. Both clamping tabs of the side clamp are fixed to the handheld bracket, and the distance between the bottoms of the two clamping tabs is greater than the distance between their tops. The side clamp can further hold the power battery, preventing it from slipping during transport. The greater distance between the bottoms of the two clamping tabs than the distance between their tops indicates that the bottoms of the clamping tabs are inclined away from the center line of the side clamp, meaning the bottoms of the clamping tabs are flared, making it easier to place the power battery into the inner cavity of the side clamp.

[0022] Furthermore, it also includes a protective cover that can be fitted onto the power battery; the protective cover includes a first cover, a second cover, and a third cover arranged sequentially. The first cover is fixedly connected to the first clamp, the second cover is fixedly connected to the handheld bracket, and the third cover is fixedly connected to the second clamp. Both ends of the second cover can extend into the inner cavities of the first cover and the third cover, respectively. The first cover, second cover, and third cover can all be transparent covers; specifically, all three covers can be made of transparent PC endurance board. The fact that the first cover, second cover, and third cover are all transparent covers allows the protective cover to provide good protection while also allowing observation of the battery's clamping position inside the cover through the transparent panels.

[0023] One end of the handheld frame and the first push rod pass through the first cover and are slidably connected to the first cover. The other end of the handheld frame, the second push rod, and the third push rod pass through the third cover and are slidably connected to the third cover.

[0024] With the protective cover in place, if a leak occurs during the handling of the power battery and liquid splashes, the liquid will directly adhere to the inner wall of the protective cover, providing excellent protection and effectively controlling the spread of risk. This reduces potential costs for businesses, such as medical expenses, equipment repairs, and insurance claims. The protective cover is designed in multiple sections, making its size adjustable to accommodate power batteries of varying lengths.

[0025] Furthermore, both the first hook and the second hook are provided with abutting parts that can abut against the end face of the second cover.

[0026] The abutment component prevents the end face of the second cover from directly contacting the third cover or the first cover after it extends into the first cover or the third cover, thus preventing the second cover from colliding with the structure of the inner cavity of the first cover or the third cover.

[0027] Compared with the prior art, the beneficial effects of this utility model are: The power battery picking device of this utility model can easily and quickly move abnormally dropped power batteries to a designated location, which can significantly save manpower and emergency response time, improve production efficiency, quickly restore on-site operations, shorten equipment downtime, avoid production capacity loss caused by abnormal events, and the device also has good protective performance, which can effectively control the spread of risks, thereby reducing the potential costs faced by enterprises such as medical compensation, equipment maintenance, and insurance claims.

[0032] Example 1 This embodiment is a first embodiment of a power battery pickup device, such as... Figure 1 As shown, it includes a handheld frame 100 and a protective cover 200, a first clamp 300, a second clamp 400, a first hook 500, and a second hook 600 mounted on the handheld frame 100. The first hook 500, the first clamp 300, the second clamp 400 and the second hook 600 are sequentially arranged on the handheld frame 100. The first clamp 300 is fixed to the handheld frame 100, and the second clamp 400, the first hook 500 and the second hook 600 are slidably connected to the handheld frame 100. The first clamp 300 and the second clamp 400 are used to clamp the opposite sides of the power battery 800 respectively; the first hook 500 and the second hook 600 can both slide to abut against the bottom surface of the power battery 800; the protective cover 200 can cover the power battery 800.

[0033] Specifically, both the first hook 500 and the second hook 600 are provided with elongated holes through which the handheld bracket 100 can pass. The handheld bracket 100 can slide along the axis of the elongated hole, thereby changing the position of the hook in the vertical direction. This allows the hook to move downwards on the handheld bracket 100 as a whole during the sliding process until the hook abuts against the bottom surface of the power battery 800. To ensure that the clamp can smoothly lift the power battery 800, when the clamp abuts against the end face of the power battery 800, the height of the contact surface between the clamp and the power battery 800 in the vertical direction is greater than 50% of the height of the power battery 800.

[0034] The working principle or process of this embodiment is as follows: When the power battery 800 pickup device of this embodiment is working, such as Figure 7 As shown, firstly, two operators hold the two ends of the grip 100 respectively and cover the protective cover 200 onto the fallen power battery 800. At this time, the power battery 800 is located between the first clamp 300 and the second clamp 400. Then, the two operators move the grip 100 so that the first clamp 300 abuts against the end face of the power battery 800, as shown. Figure 8 As shown. Immediately afterwards, the operator near the second chuck 400 drives the second chuck 400 to move towards the power battery 800 until the second chuck 400 also comes into contact with the end face of the power battery 800, as shown. Figure 9 As shown. After the second clamp 400 abuts against the end face of the power battery 800, the operator near the first clamp 300 presses down the handheld bracket 100. At this time, the handheld bracket 100 can lift one side of the second clamp 400 with the first hook 500 as a support point. When one side of the second clamp 400 on the handheld bracket 100 is lifted, the power battery 800 clamped between the first clamp 300 and the second clamp 400 can be lifted. After the power battery 800 is lifted, the operator on the side of the second clamp 400 pushes the second hook 600 to slide on the handheld bracket 100 until the second hook 600 abuts against the bottom surface of the power battery 800, that is, the second hook 600 extends into the bottom of the power battery 800, as shown. Figure 10 As shown. After the second hook 600 extends into the bottom of the power battery 800, the operator near the first clamp 300 slowly releases the handle 100 upwards until the handle 100 returns to its original position, and the bottom surface of the power battery 800 returns to the bottom surface, as shown. Figure 11 As shown. Then, the operator near the second clamp 400 presses down the handheld bracket 100. The handheld bracket 100, using the second hook 600 as a support point, lifts the first clamp 300. Then, the operator near the first clamp 300 pushes the first hook 500 to slide on the handheld bracket 100 until the first hook 500 abuts against the bottom surface of the power battery 800, as shown. Figure 12 As shown. After the first hook 500 abuts against the bottom surface of the power battery 800, the operator near the second clamp 400 slowly releases the handhold 100 upwards, and the handhold 100 returns to its original position. At this time, the first hook 500 and the second hook 600 respectively lift the opposite sides of the bottom surface of the power battery 800, as shown. Figure 13 As shown, the operator can lift the handheld bracket 100 to move the power battery 800 to a designated location. If the power battery 800 leaks and splashes during the process of moving the power battery 800, the splashed liquid will directly spray onto the inner wall of the protective cover 200.

[0035] The beneficial effects of this embodiment are as follows: The power battery 800 pickup device in this embodiment can easily and quickly move abnormally dropped power batteries 800 to a designated location, which can significantly save manpower and emergency response time, improve production efficiency, quickly restore on-site operations, shorten equipment downtime, avoid production capacity loss caused by abnormal events, and the device also has good protective performance, which can effectively control the spread of risks, thereby reducing the potential costs faced by enterprises such as medical compensation, equipment maintenance, and insurance claims.

[0036] Example 2 This embodiment is a second embodiment of a power battery pickup device, such as... Figures 2-6 As shown, this embodiment further defines the hook and clamp based on embodiment one.

[0037] Specifically, the first hook 500 includes a first sliding part 510 and a first lifting part 520 connected in sequence. The first sliding part 510 and the first lifting part 520 are L-shaped. The first sliding part 510 is slidably connected to the hand holder 100. The first lifting part 520 can slide to abut against the bottom surface of the power battery 800. The second hook 600 includes a second sliding part 610 and a second lifting part 620 connected in sequence. The second sliding part 610 and the second lifting part 620 are L-shaped. The second sliding part 610 is slidably connected to the hand holder 100. The second lifting part 620 can slide to abut against the bottom surface of the power battery 800.

[0038] Specifically, the connection between the first sliding part 510 and the first lifting part 520 is provided with a first rounded corner 530; the connection between the second sliding part 610 and the second lifting part 620 is provided with a second rounded corner 630.

[0039] Specifically, in the vertical direction, the center planes of the first hook 500, the first clamp 300, the second clamp 400, and the second hook 600 coincide.

[0040] Specifically, the first hook 500 is provided with a first push rod 540, which is installed on the side of the first hook 500 away from the first clamp 300; The second hook 600 is provided with a second push rod 640, which is installed on the two sides of the second hook 600 away from the second clamp 400.

[0041] Specifically, a first slot 310 is provided on the side of the first chuck 300 near the first hook 500. The end of the first push rod 540 passes through the first hook 500 and is threadedly connected to the first hook 500. A first hook 541 is fixedly installed on the end of the first push rod 540. When the first hook 500 slides to abut against the bottom surface of the power battery 800, the first push rod 540 can rotate until the first hook 541 engages with the first slot 310. The second clamp 400 has a second slot 410 on both sides near the second hook 600. The end of the second push rod 640 passes through the second hook 600 and is threadedly connected to the second hook 600. The end of the second push rod 640 is fixedly installed with a second hook 641. When the second hook 600 slides to abut against the bottom surface of the power battery 800, the second push rod 640 can rotate until the second hook 641 engages with the second slot 410.

[0042] Specifically, the first push rod 540 has a first bent portion 542 at the end away from the first hook 541, and the bending direction of the first bent portion 542 is the same as the direction of the first hook 541. The second push rod 640 has a second curved portion 642 at both ends away from the second hook 641, and the bending direction of the second curved portion 642 is the same as the direction of the second hook 641.

[0043] Specifically, a third push rod 420 is fixedly installed on the second chuck 400, and the third push rod 420 is installed on the side of the second chuck 400 away from the first chuck 300.

[0044] The beneficial effects of this embodiment are as follows: The first hook 500 and the second hook 600 have the same structure, both including a sliding part and a lifting part, which are perpendicular to each other, allowing the lifting part to smoothly extend into the bottom of the raised power battery 800 and lift it up. When the handheld bracket 100 is raised, the connection between the sliding part and the lifting part serves as a fulcrum. A rounded corner at the connection makes it easier for the operator to raise the handheld bracket 100. Vertically, the center surfaces of the first hook 500, the first clamp 300, the second clamp 400, and the second hook 600 coincide; that is, the first clamp 300 is located in the middle of the first hook 500, and the second clamp 400 is located in the middle of the second hook 600. This allows the force applied to the battery when the clamps lift it to more easily raise the battery. When the operator needs to drive the hook to slide on the handheld bracket 100, they can push a push rod to drive the hook to slide on the handheld bracket 100, making operation easier. The hook and slot design allows for relative fixation between the clamp and the hook, enabling synchronous movement of the clamp and hook on the handheld frame 100. During the movement of the power battery 800, only one of the clamp or hook needs to be controlled to prevent them from sliding on the handheld frame 100, making it easier for the operator. The hook and push rod are threaded together, allowing the push rod to rotate on the hook while preventing relative sliding between the hook and the push rod. The operator can hold the curved part to rotate the push rod, making it easier to operate. Furthermore, the curved part and hook face the same direction, allowing the operator to determine if the hook is engaged with the slot by observing the direction of the push rod's rotation. The third push rod 420 further facilitates the operator in pushing the second clamp 400 to slide on the handheld frame 100.

[0045] Example 3 This embodiment is a third embodiment of a power battery pickup device, such as... Figures 2-6 As shown, this embodiment further defines other structures of the device based on embodiment two.

[0046] Specifically, it also includes a side clamp 700 for holding the power battery 800. The two clamping pieces 710 of the side clamp 700 are fixed to the handheld bracket 100, and the distance between the bottom of the two clamping pieces 710 is greater than the distance between the top of the two clamping pieces 710.

[0047] Specifically, the protective cover 200 includes a first cover 210, a second cover 220 and a third cover 230 arranged in sequence. The first cover 210 is fixedly connected to the first clamp 300, the second cover 220 is fixedly connected to the hand holder 100, and the third cover 230 is fixedly connected to the second clamp 400. The two ends of the second cover 220 can respectively extend into the inner cavity of the first cover 210 and the third cover 230.

[0048] One end of the handheld bracket 100 and the first push rod 540 pass through the first cover 210 and are slidably connected to the first cover 210. The other end of the handheld bracket 100 and the second push rod 640 and the third push rod 420 pass through the third cover 230 and are slidably connected to the third cover 230.

[0049] Specifically, both the first hook 500 and the second hook 600 are provided with abutting parts that can abut against the end face of the second cover 220.

[0050] The beneficial effects of this embodiment are as follows: The side clamp 700 can further clamp the power battery 800, preventing it from slipping during transport. The distance between the bottoms of the two clamping pieces 710 is greater than the distance between their tops, meaning the bottoms of the clamping pieces 710 are inclined away from the centerline of the side clamp 700, essentially making the bottoms of the clamping pieces 710 flared, which facilitates placing the power battery 800 into the inner cavity of the side clamp 700. The protective cover 200 is configured in multiple parts, allowing its size to be adjusted to cover power batteries 800 of various lengths. The abutment prevents the end face of the second cover 220 from directly contacting the third cover 230 or the first cover 210 after it extends into the first cover 210 or the third cover 230, thus preventing collisions between the second cover 220 and the inner structure of the first cover 210 or the third cover 230.

[0051] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
