Description

Technical Field

[0001] This utility model belongs to the field of battery swapping technology and relates to a battery lifting device. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include four main types: hybrid electric vehicles (HEVs), battery electric vehicles (BEVs, including solar-powered vehicles), fuel cell electric vehicles (FCEVs), and other new energy vehicles (such as supercapacitors, flywheels, and other high-efficiency energy storage devices). Unconventional vehicle fuels refer to fuels other than gasoline and diesel.

[0003] Currently, in addition to small new energy vehicles such as passenger cars and delivery vehicles, the market also offers larger new energy vehicles such as trailers, trucks, buses, and heavy trucks. Correspondingly, the battery packs of these larger new energy vehicles are also much larger in weight and volume. For example, the battery packs of some new energy heavy trucks weigh over 3 tons. Therefore, swapping these batteries requires specialized equipment to lift and move the battery packs. The battery packs also have frames for suspension and movement. The battery swapping system mainly includes a lifting device for connecting and disconnecting from the frame on top of the battery, and a structure for lifting and moving the lifting device (usually horizontal X and Y-axis tracks, while the lifting device can be raised and lowered to create a Z-axis effect). Because the battery packs of heavy trucks are large in mass and volume, not only are several (at least four) power structures installed on the lifting device, but also a certain number of sensors are installed, such as sensors for sensing the position of the battery pack and / or frame, and sensors for sensing the pressure on the stressed structure. These sensors have many wires, which are usually pulled down from the track structure above the lifting device. This can easily lead to a large number of movable wires on the lifting device, which can easily become tangled or even broken, resulting in poor performance. Utility Model Content

When placing or removing the battery pack (which has a frame for lifting on top), the support parts are initially located on the side of the frame. Then, the lifting plate moves downward until the support parts are located below the top frame of the battery pack. The drive mechanism then drives the sliding seat, lifting components, and support parts to move, so that the support parts are located below the frame. After that, the lifting plate rises, thus raising the battery pack. After the battery pack is moved to the designated position and lowered, the support parts move horizontally below the frame, moving to the side of the frame. Then, the lifting plate is raised to separate the lifting device from the battery pack.

[0023] During use, the wiring of all sensors on the hoisting platform is connected to the upper frame structure, effectively preventing the wires from becoming entangled with other external structures. The wires between the hoisting platform and the frame structure are spirally wound around a cable tie (similar to vines), and cable ties can be used to secure them to the tie, depending on the situation. This not only ensures the stability of the wiring between the hoisting platform and the frame structure, but also allows the cable tie to elastically deform during the hoisting platform's raising and lowering process, thus not affecting the normal lifting and lowering of the platform and resulting in better performance.

[0049] The bottom of the lifting plate is vertically provided with several guide seats 26, and each of the four sides of the lifting plate has at least one guide seat 26. The outer side of the bottom of the guide seat 26 is inclined. The inclined part of the guide seat 26 is provided with a collision plate 27 that fits against the guide seat 26. The top of the collision plate 27 is vertically provided with a fitting part 28, and the bottom is horizontally provided with a stabilizing part 29. The collision plate 27, the fitting part 28, and the stabilizing part 29 are integrally formed, and the fitting part 28 and the stabilizing part 29 are both fitted against the guide seat 26. The lower side of the collision plate 27 is provided with a buffer part 30, which is made of elastic material.

[0050] The inclined portion of the guide seat 26 is horizontally provided with a first dovetail groove 31. The X end of the first dovetail groove 31 passes through the guide seat 26, and the -X end has a set distance from the edge of the guide seat 26 on the -X side.

[0051] The guide seat 26 is provided with a positioning post 35 on the X side by a horizontal threaded connection. The end of the positioning post 35 is provided with a positioning disc 36, which abuts against the impact plate 27 and the X side of the buffer part 30. The second dovetail groove 34 is inclined, and the -X end of the second dovetail groove 34 is higher than the X end.

[0052] This utility model provides a battery lifting device. In practical use, the lifting plate 1 also has a frame structure (hereinafter referred to as "frame structure," which is not the structure claimed in this application and will not be described in detail here) for translating and raising / lowering the lifting plate 1. Each of the four corners of the top of the lifting plate 1 has a wheel for the overhead lifting cable to pass through and raise / lower the lifting plate 1. When placing or removing a battery pack (which has a frame for lifting on top), the support parts 7 are initially located on the sides of the frame. Then, the lifting plate 1 moves downwards until the support parts 7 are located below the top frame of the battery pack. The drive mechanism then drives the sliding seat 5, the lifting component 6, and the support parts 7 to move, positioning the support parts 7 below the frame. The lifting plate 1 then rises, raising the battery pack. After the battery pack is moved to the designated position and lowered, the support parts 7 move horizontally below the frame, moving to the side of the frame. Raising the lifting plate 1 then separates the lifting device from the battery pack.

[0053] During use, the wires of all sensors on the hoisting platform 1 are connected to the upper frame structure, which effectively prevents the wires from getting tangled with other external structures. Meanwhile, the wires between the hoisting platform 1 and the frame structure are spirally wound around the cable tie 8 (similar to vines). Depending on the situation, cable ties or similar items can be used to secure the wires to the cable tie 8. This not only ensures the stability of the wires between the hoisting platform 1 and the frame structure, but also allows the cable tie 8 to elastically deform during the lifting and lowering of the hoisting platform 1, thus not affecting its normal lifting and lowering, resulting in better performance.

[0054] During use, the cable tie 8 is held in place by the gathering member 9, which effectively prevents the cable tie 8 from deforming laterally and interacting with the external structure. The wire pass-through port 10 allows various wires to easily pass through the gathering member 9 and connect to various electrical components.

[0055] During actual battery installation, the lifting plate 1 descends, with the bottom of the guide seat 26 lower than the support part 7. The frame at the top of the battery pack can act on the buffer part 30 below the guide seat 26. Since the buffer part 30 is inclined, if the position of the lifting plate 1 is slightly offset (usually not by much), the frame can then act on the lower side of the buffer part 30, driving the lifting plate 1 to move. Because the four sides of the bottom of the lifting plate 1 have guide seats 26 (with corresponding columns or rods on the frame), the lifting plate 1 can move to the required position, and finally, the fitting part 28 fits against the inner side of the corresponding frame, thus ensuring the relative position of the entire lifting plate 1 and the battery pack.

[0056] Then the drive motor 14 starts and simultaneously drives the two drive cylinders 15 to rotate. Since the angle of the passive lead screw 18 is fixed, the drive cylinder 15 can pull the passive lead screw 18 towards the drive motor 14 when it rotates, which also drives the sliding cylinder 17 to slide on the drive frame 16. At the same time, the extension arm 19 and the drive arm 20 also move towards the drive motor 14. After the drive port 21 acts on the drive column 22, the drive column 22, the sliding seat 5, the lifting part 6, and the support part 7 all move outward until the lifting part 6 touches the inner side of the corresponding frame.

[0057] Then, the lifting plate 1 is raised, the support part 7 abuts against the bottom of the corresponding frame, and the anti-slip part 13 is located on the outside of the corresponding frame, thereby improving the lifting stability of the frame. The sliding seat 5, lifting component 6, support part 7, and reinforcing member 12 form a shape with a certain thickness, which improves the lifting stability of the battery and also ensures the strength of this part of the structure. Furthermore, since the lifting slide rail 4 is located at the top of the load-bearing column 3, this further ensures the strength and stability of the battery lifting.

[0058] This application requires only one dual-axis motor to simultaneously and synchronously drive the four lifting components 6, thus reducing production and usage costs and preventing asynchrony issues that can easily occur when each component is driven independently. Meanwhile, the anti-detachment disc 23 at the top of the drive column 22 ensures stable interaction between the drive arm 20 and the drive column 22.

[0059] The structure used to raise the lifting plate 1 has a vertical cylinder at the bottom, with a flared guide at the bottom of the cylinder. During the raising of the lifting plate 1, the top pointed part of the anti-sway bar 24 is first inserted into the cylinder (the guide makes the insertion smoother). After the battery pack is raised to the specified height, the outer wall of the anti-sway bar 24 fits against the inner wall of the cylinder. In this way, the anti-sway bar 24 and the cylinder can improve the stability of the lifting plate 1 and the structure above, and reduce the swaying of the battery pack during the translation process.

[0060] The guide seat 26 is fixedly connected to the lifting plate 1, while the impact plate 27 is made of a harder and more wear-resistant material. The final mating part 28 is mated to the frame on top of the battery pack. Because the impact plate 27 (made of the same material as the mating part 28 and the stabilizing part 29) has high strength and wear resistance, it can effectively ensure the interaction between the impact plate 27 and the battery pack frame. Similarly, if the lifting plate 1 deviates at an angle, causing the stabilizing part 29 to come into contact with the top of the frame on top of the battery pack, it can also effectively prevent damage to the guide seat 26. At the same time, the impact plate 27 is detachable and replaceable, so even if the impact plate 27 is deformed, it can be simply replaced, which is simple and convenient.

[0061] The buffer part 30 is made of elastic material, which also has great strength and wear resistance (such as special rubber), so it can better prevent the frame at the top of the battery pack from being subjected to hard rigid impacts, resulting in better performance.

[0062] When replacing the buffer section 30 and / or the impact plate 27, simply rotate the positioning plate 36 and remove the positioning post 35. Then, directly move the buffer section 30 and / or the impact plate 27 to disassemble it. Subsequent installation of a new one follows the reverse process, making it simple and convenient. The X-side of the first dovetail groove 31 does not penetrate the guide seat 26, and the X-side of the second dovetail groove 34 does not penetrate the buffer section 30. Therefore, there is no need to limit the sides of the impact plate 27 or the buffer section 30. Instead, the positioning plate 36 is used to limit and block the X-side of the impact plate 27 and the buffer section 30 to ensure their positional stability, resulting in better performance. The positioning plate 36 does not affect the normal use of the buffer section 30; that is, the positioning plate 36 does not act on the frame at the top of the battery pack.

[0063] Furthermore, since the second dovetail groove 34 is inclined (with a small inclination angle, only shown in the figure for illustration) and the height of -X is relatively high, while the buffer part 30 is mainly subjected to the upward (reaction) force of the battery pack frame during use, and the bottom of the second dovetail groove 34 does not penetrate the buffer part 30, the stability of the buffer part 30 during use can be further improved.

[0064] In another embodiment, such as Figure 11 As shown, the lower side of the buffer part 30 has a countersunk hole, and the impact plate 27 is plate-shaped with a hole coaxial with the countersunk hole. Then, a bolt passes through the countersunk hole and the hole on the impact plate 27 and is threadedly connected to the guide seat 26. This also allows the impact plate 27 to be replaced, but several bolts are needed to connect the three structures.

[0065] In another embodiment, the guide seat 26 is driven to reciprocate by a cylinder, hydraulic cylinder, or electric actuator (parallel to the top of the load-bearing column 3), and each guide seat 26 has a separate cylinder, hydraulic cylinder, or electric actuator.

[0066] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0067] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
