Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to a lightweight power battery module lifting tool. Background Technology

[0002] The new energy industry is developing rapidly, and the market's energy requirements for power battery packs are constantly increasing. This requires placing more battery modules in a limited battery pack, which in turn reduces the space between modules and makes the module assembly process more difficult.

[0003] The existing method of manually placing battery modules into the battery pack is time-consuming and labor-intensive, and cannot guarantee the safety and accuracy of placing the battery modules. Utility Model Content

[0004] In view of this, the present invention provides a lightweight power battery module lifting tool to solve the problems of time-consuming and labor-intensive operation and inability to guarantee the safety and accuracy of battery module placement in the prior art.

[0005] This utility model provides a lightweight power battery module lifting device, including:

[0006] Base plate;

[0007] A lifting ring is provided on the upper surface of the base plate;

[0008] The hoisting assembly includes a telescopic device mounted on a base plate, a guide plate fixedly mounted on the lower surface of the base plate, a transmission assembly mounted on the telescopic device and the guide plate, and a lifting pin extending through the guide plate. The transmission assembly is adapted to cause the lifting pin to have a first state in which its end extends out of the guide plate and a second state in which its end is located inside the guide plate under the action of the telescopic device. The telescopic device is connected to a controller.

[0009] Multiple slots are provided on the upper surface of the power battery module. With the lifting pin in the second position, the lifting ring is hoisted using a hook, causing the lifting pin on the guide plate to extend into the slot of the power battery module. Then, the lifting pin is placed in the first position, so that the extended lifting pin is engaged within the slot of the power battery module. The power battery module can then be hoisted and moved into the battery pack using the hook. This application makes the hoisting of battery modules time-saving and labor-saving, and also improves safety and accuracy through the hoisting method.

[0010] In one optional embodiment, the guide plate is an inverted U-shaped plate, the top end of the guide plate is fixedly connected to the lower surface of the base plate, and the bottom end of the guide plate is provided with a through hole penetrating the two support arms of the guide plate, and the lifting pin is disposed in the through hole.

[0011] The guide plate is configured as an inverted U-shaped plate to guide the movement of the transmission assembly, and the through hole can limit the lifting pin in the extension direction of the guide plate support arm.

[0012] In one optional embodiment, the lifting pin is horizontally positioned and has an adjustment groove, which is inclinedly positioned on the bottom surface of the lifting pin.

[0013] In one optional implementation, the transmission assembly includes:

[0014] The first connecting rod has one end connected to the telescopic device and the other end located between the two arms of the guide plate;

[0015] The second connecting rod is U-shaped and located between the two arms of the guide plate. The bottom end of the second connecting rod is located below the lifting pin, and the top end of the second connecting rod is fixedly connected to the end of the first connecting rod away from the telescopic device.

[0016] An adjusting pin is fixedly disposed between the two arms of the second connecting rod and is adapted to the adjusting channel. When the adjusting pin is located at the top of the adjusting channel, the lifting pin is in a first state; when the adjusting pin is located at the bottom of the adjusting channel, the lifting pin is in a second state.

[0017] The first connecting rod and the second connecting rod can form a connecting rod. The telescopic device drives the connecting rod to move up and down, which in turn causes the second connecting rod to drive the adjusting pin to move up and down. Because the adjusting pin moves up and down, and the adjusting slot is inclined on the lifting pin, the adjusting pin will exert a force on the side wall of the adjusting slot during its movement. Moreover, the lifting pin is set in the through hole, so that the lifting pin can move left and right in the through hole. This also gives the lifting pin a first state of extending out of the guide plate and a second state of being located inside the guide plate. When the lifting pin is in the first state, the guide plate can freely enter and exit the slot on the upper surface of the power battery module. When the bottom end of the guide plate, that is, the position of the lifting pin, extends into the slot on the upper surface of the power battery module, the telescopic device adjusts the position of the first connecting rod and the second connecting rod so that the lifting pin is in the first state of extending out. The lifting pin is stuck inside the slot, which allows the power battery module to be hoisted and moved.

[0018] In one optional implementation, a limiting component is further included, the limiting component comprising:

[0019] A limiting groove is provided on one of the support arms of the guide plate and communicates with the through hole;

[0020] A limiting protrusion is provided on the side wall of the lifting pin and located within the limiting groove;

[0021] A limiting shaft is located within the limiting groove and connected to the support arm of the guide plate, and the limiting shaft passes through the limiting protrusion.

[0022] When the lifting pin moves left and right in the through hole, the limiting protrusion follows the lifting pin and moves along the limiting axis in the limiting groove, which can prevent the lifting pin from deflecting along the central axis of the through hole, causing the adjusting pin to get stuck on the lifting pin.

[0023] In one optional implementation, the limiting component further includes:

[0024] A limiting block is fixedly mounted on the limiting shaft, and the limiting protrusion is located between the guide plate support arm and the limiting block.

[0025] The limiting protrusion is located between the guide plate support arm and the limiting block, which can limit the movement range of the lifting pin.

[0026] In one optional implementation, the limiting component further includes:

[0027] A connecting block is connected and disposed between the two arms of the guide plate. The connecting block is located above the through hole, and there is a limiting gap between the connecting block and the top of the guide plate. The first connecting plate is located within the limiting gap, and the connecting block is located between the two arms of the second connecting rod.

[0028] The limiting gap restricts the movement range of the first connecting rod, allowing the adjusting pin to move between the top and bottom positions of the adjusting slot. The connecting block is located between the two arms of the second connecting rod and guides the movement of the second connecting rod.

[0029] In one optional embodiment, the bottom end of the guide plate is provided with a guide block having a guiding slope. The guide block allows the guide plate to smoothly extend into the slot on the upper surface of the power battery module.

[0030] In one optional embodiment, the lower surface of the base plate is further provided with a plurality of limiting claws, which are respectively disposed at both ends of the base plate. The limiting claws can align the relative position between the base plate and the power battery module, thereby allowing the guide plate to smoothly extend into the slot on the upper surface of the power battery module when it approaches the power battery module.

[0031] In one optional embodiment, the hoisting assembly consists of two sets, respectively disposed at both ends of the base plate;

[0032] Each hoisting assembly consists of two sets of transmission components.

[0033] There are two controllers, and the two controllers and two telescopic devices are connected in series.

[0034] Multiple sets of hoisting components and multiple sets of transmission components can correspond to multiple slots set on the upper surface of the power battery module. Hoisting can be carried out through multiple slots set on the upper surface of the power battery module, which can increase the safety and accuracy of the hoisting process.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] The new energy industry is developing rapidly, and the market's energy requirements for power battery packs are constantly increasing. This requires placing more cells within a limited pack volume, which in turn reduces the space between modules, making the module assembly process more difficult. If an automated solution is adopted, special equipment must be selected to meet the lifting requirements due to size and weight limitations, resulting in high equipment investment costs, large footprint, and low utilization. If manual assembly is used, issues such as ease of lifting, lifting safety, and accuracy of placement must be addressed. Therefore, considering all aspects, this utility model's semi-automatic clamp requires the operator to simultaneously control two controllers to activate the clamping of the module, effectively preventing misoperation and avoiding the risk of the module falling. Secondly, the clamp adopts a built-in pin design, which can be driven by a guide block to pull the lifting pin into the internal slot of the module's end plate, lifting the module through the internal slot, eliminating concerns about insufficient gaps between modules during assembly. Finally, the guide block and limiting claws installed in the clamp allow the operator to more easily determine the module's position, facilitating precise placement into the assembly box. In summary, this lightweight power battery module lifting clamp offers the advantages of low cost, high safety, and portability.

[0045] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a lightweight power battery module lifting device is provided, comprising:

[0047] Base plate 1;

[0048] A lifting ring 2 is disposed on the upper surface of the base plate 1; a connector may be disposed on the upper surface of the base plate 1, and the lifting ring 2 is connected to the base plate 1 through the connector.

[0049] The hoisting assembly includes a telescopic device 3 mounted on a base plate 1, a guide plate 4 fixedly mounted on the lower surface of the base plate 1, a transmission assembly mounted on the telescopic device 3 and the guide plate 4, and a lifting pin 5 penetrating the guide plate 4. The transmission assembly is adapted to cause the lifting pin 5 to have a first state in which its end extends out of the guide plate 4 and a second state in which its end is located inside the guide plate 4 under the action of the telescopic device 3. The telescopic device 3 is connected to a controller.

[0050] The telescopic device 3 can be a telescopic motor or a telescopic cylinder. When the telescopic device 3 is a telescopic cylinder, the telescopic cylinder can be connected to compressed gas. The controller can be a control switch for controlling the extension and retraction of the telescopic device 3. A handle 18 can be provided on the upper surface of the base plate 1, and the control switch can be provided on the handle 18. The transmission component can be a connector. The guide plate 4 can be hollow. The connector is located inside the guide plate 4 and its top end is connected to the telescopic device 3. The lifting pin 5 is horizontally positioned at the bottom of the guide plate 4. The bottom end of the connector and the end of the lifting pin 5 are connected in a wedge shape. A return spring is provided between this end of the lifting pin 5 and the inner sidewall of the guide plate 4. When the telescopic device 3 drives the connector to move downward, the bottom end of the connector pushes the lifting pin 5 to move horizontally and penetrate the sidewall of the guide plate 4, so that the lifting pin 5 is in the first extended state. When the telescopic device 3 drives the connector to move upward, the return spring resets the lifting pin 5, so that the lifting pin 5 is in the second state inside the guide plate 4.

[0051] Multiple slots are provided on the upper surface of the power battery module. With the lifting pin 5 in the second position, the lifting ring 2 is lifted using a hook, causing the lifting pin 5 on the guide plate 4 to extend into the slot of the power battery module. Then, the lifting pin 5 is placed in the first position, so that the extended lifting pin 5 is engaged within the slot of the power battery module. The power battery module can then be lifted and moved into the battery pack using the hook. This application makes lifting the battery module time-saving and labor-saving, and also improves safety and accuracy through the lifting method.

[0052] In one embodiment, the guide plate 4 is an inverted U-shaped plate. The top end of the guide plate 4 is fixedly connected to the lower surface of the base plate 1. The bottom end of the guide plate 4 is provided with a through hole 19 penetrating the two arms of the guide plate 4, and the lifting pin 5 is disposed in the through hole 19. The through hole 19 can be horizontally disposed, and the two arms of the guide plate 4 can be plate-shaped. The through hole 19 can be vertically disposed on the two arms of the guide plate 4. The slot on the upper surface of the power battery module should be opposite to the guide plate 4, so that the extension direction of the lifting pin 5 is perpendicular to the side wall of the slot, so that the lifting pin 5 can be fully engaged in the inner side of the slot during hoisting. The slot can be an opening on the power battery module, or it can be composed of two connected and vertically distributed slots. The upper slot is connected to the upper surface of the power battery module, and the diameter of the lower slot is larger than that of the upper slot. The lifting pin 5 is in a second state and extends into the lower slot. When it changes from the second state to the first state, the lifting pin 5 is engaged in the lower slot.

[0053] The guide plate 4 is configured as an inverted U-shaped plate to guide the movement of the transmission assembly, and the through hole 19 can limit the lifting pin 5 in the extension direction of the guide plate 4 arm.

[0054] In one embodiment, the lifting pin 5 is horizontally positioned and has an adjusting groove 6, which is inclinedly positioned on the bottom surface of the lifting pin 5. The cross-section of the adjusting groove 6 can be an inclined rectangle, or it can include a first connecting surface, a second connecting surface, and a third connecting surface connected in sequence. The first connecting surface is an inclined surface, the second connecting surface is located at the top of the adjusting groove 6, and the third connecting surface is a convex surface that protrudes towards the location of the first connecting surface. A chamfer can be provided at the connection point of the first connecting surface, the second connecting surface, and the third connecting surface to prevent the adjusting pin 9 from getting stuck. The second connecting surface and the third connecting surface can also be an arc-shaped structure.

[0055] In one embodiment, the transmission assembly includes:

[0056] The first connecting rod 7 has one end connected to the telescopic device 3 and the other end located between the two arms of the guide plate 4;

[0057] The second connecting rod 8 is U-shaped and located between the two arms of the guide plate 4. The bottom end of the second connecting rod 8 is located below the lifting pin 5, and the top end of the second connecting rod 8 is fixedly connected to the end of the first connecting rod 7 away from the telescopic device 3.

[0058] An adjusting pin 9 is fixedly disposed between the two arms of the second connecting rod 8 and adapted to the adjusting groove 6. When the adjusting pin 9 is located at the top of the adjusting groove 6, the lifting pin 5 is in a first state; when the adjusting pin 9 is located at the bottom of the adjusting groove 6, the lifting pin 5 is in a second state. The adjusting pin 9 can always be located within the adjusting groove 6, or it can enter the adjusting groove 6 from below under the action of the second connecting rod 8. In this case, the size of the bottom end of the adjusting groove 6 can be larger than the size of the top end to facilitate the entry and exit of the adjusting pin 9.

[0059] The first connecting rod 7 and the second connecting rod 8 can form a connecting rod. The first connecting rod 7 can be configured as an inverted U-shape and fixedly connected to the outer wall of the second connecting rod 8. The telescopic device 3 drives the connecting rod to move up and down, thereby causing the second connecting rod 8 to drive the adjusting pin 9 to move up and down. Because the adjusting pin 9 moves up and down, and the adjusting slot 6 is inclinedly set on the lifting pin 5, the adjusting pin 9 will exert a force on the side wall of the adjusting slot 6 during its movement. Moreover, the lifting pin 5 is set in the through hole 19, thereby enabling the lifting pin 5 to... The left and right movement within the through hole 19 allows the lifting pin 5 to have a first state of extending out of the guide plate 4 and a second state of being located inside the guide plate 4. When the lifting pin 5 is in the first state, the guide plate 4 can freely enter and exit the slot on the upper surface of the power battery module. When the bottom end of the guide plate 4, which is the position of the lifting pin 5, extends into the slot on the upper surface of the power battery module, the position of the first connecting rod 7 and the second connecting rod 8 is adjusted by the telescopic device 3 so that the lifting pin 5 is in the first state of extending out. The lifting pin 5 is stuck inside the slot, allowing the power battery module to be hoisted and moved.

[0061] The limiting groove 10 is disposed on one of the support arms of the guide plate 4 and communicates with the through hole 19; the limiting groove 10 can be disposed above the through hole 19.

[0062] The limiting protrusion 11 is provided on the side wall of the lifting pin 5 and located within the limiting groove 10;

[0063] A limiting shaft 12 is located within the limiting groove 10 and connected to the support arm of the guide plate 4. The limiting shaft 12 passes through the limiting protrusion 11. The end of the limiting shaft 12 may be threaded and screwed into the support arm of the guide plate 4.

[0064] When the lifting pin 5 moves left and right in the through hole 19, the limiting protrusion 11 follows the lifting pin 5 and moves along the limiting axis 12 in the limiting groove 10, which can prevent the lifting pin 5 from deflecting along the central axis of the through hole 19, so that the adjusting pin 9 is stuck on the lifting pin 5.

[0065] In one embodiment, the limiting component further includes:

[0066] A limiting block 13 is fixedly mounted on the limiting shaft 12, and the limiting protrusion 11 is located between the guide plate 4 support arm and the limiting block 13. The limiting block 13 can be located at the end of the limiting shaft 12.

[0067] The limiting protrusion 11 is located between the guide plate 4 arm and the limiting block 13, which can limit the movement range of the lifting pin 5.

[0068] In one embodiment, the limiting component further includes:

[0069] A connecting block 14 is connected and disposed between the two arms of the guide plate 4. The connecting block 14 is located above the through hole 19, and there is a limiting gap 15 between the connecting block 14 and the top end of the guide plate 4. The first connecting plate is located within the limiting gap 15, and the connecting block 14 is located between the two arms of the second connecting rod 8.

[0070] The limiting gap 15 restricts the movement range of the first connecting rod 7, allowing the adjusting pin 9 to move between the top and bottom positions of the adjusting slot 6. The connecting block 14 is located between the two arms of the second connecting rod 8, and the connecting block 14 guides the movement of the second connecting rod 8.

[0071] In one embodiment, the bottom end of the guide plate 4 is provided with a guide block 16 having a guiding slope. The guide block 16 allows the guide plate 4 to smoothly extend into the slot on the upper surface of the power battery module. A gap may be provided between the bottom end of the guide block 16 and the second connecting rod 8 to prevent the guide block 16 from interfering with the movement of the second connecting rod 8.

[0072] In one embodiment, the lower surface of the base plate 1 is further provided with a plurality of limiting claws 17, which are respectively disposed at both ends of the base plate 1. The limiting claws 17 can align the relative position between the base plate 1 and the power battery module, thereby allowing the guide plate 4 to smoothly extend into the slot on the upper surface of the power battery module when it approaches the power battery module. The limiting claws 17 can be arranged in pairs, respectively disposed at both ends of the base plate 1.

[0073] In one embodiment, the hoisting assembly consists of two sets, respectively located at both ends of the base plate 1;

Lifting can be performed simultaneously through multiple slots on the upper surface of the power battery module, increasing safety and accuracy during the lifting process. Two controllers and two telescopic devices 3 are connected in series. Operators need to operate both controllers simultaneously to adjust the extension and retraction of the telescopic devices 3, and the two telescopic devices 3 can move synchronously. The lifting components and limiting claws 17 can be located at different ends of the base plate 1.
