Description

Technical Field

[0001] This utility model relates to the field of battery swapping equipment technology, and specifically to a floating positioning component for battery swapping equipment. Background Technology

[0002] New energy vehicles that use battery swapping for energy replenishment involve moving a battery swapping cart under the vehicle to remove and install batteries, thereby achieving efficient energy replenishment.

[0003] Before battery installation and removal, the upper structure used for battery disassembly automatically aligns and positions the new energy vehicle. The drive unit used for positioning is susceptible to various structural factors that can lead to positioning errors, affecting battery swapping efficiency. This has led to the development of floating devices for automatic positioning, achieving accurate positioning. Existing technologies, such as patents CN207579841U and CN108058688B, disclose related technical solutions that utilize chains to achieve floating.

[0004] The existing technology has the following technical problems: 1. During the floating process, the chain structure is supported by four points of suspension. When there is a deviation in the chain length or a large force on one point, the lifting platform will tilt, which will cause the horizontal direction of the platform to change and affect the positioning accuracy; 2. When the battery is pushed into the battery compartment, due to the shift of the center of gravity, the four-point suspension of the chain becomes free, which will automatically generate a large height difference and cause the front and rear ends to tilt, which will have a very adverse effect on the automatic control. Summary of the Invention

[0005] This utility model provides a floating positioning component for battery swapping equipment. It uses a universal ball as rigid support and a spring for reset. Under the constraint force generated during positioning, the floating platform can move arbitrarily within a preset range on the lifting platform to ensure accurate positioning and prevent deviation in the height direction.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a floating positioning component, which is disposed between a floating platform and a lifting platform. The key features are: a floating platform support component that supports the floating platform to move arbitrarily within a preset range on the lifting platform under the action of positioning constraint force, and a reset spring component that resets the floating platform to its position after the positioning constraint force is released.

[0007] Furthermore, the floating platform support assembly includes a plurality of omnidirectional balls disposed on the lifting platform and arranged along the length direction of the lifting platform, and a support plate fixed on the floating platform and in contact with the omnidirectional balls.

[0008] Furthermore, at least two sets of the floating platform support components are provided along the width direction of the floating platform.

[0009] Furthermore, the reset spring assembly is provided in multiple sets, each set of reset spring assembly includes at least one longitudinal reset spring disposed between the floating platform and the lifting platform along the length direction of the lifting platform and at least one transverse reset spring disposed along the width direction of the lifting platform.

[0010] Furthermore, the lifting platform is provided with a longitudinal mounting sleeve for installing the longitudinal return spring and a transverse mounting sleeve for installing the transverse spring, and the floating platform is provided with a longitudinal limiting plate for limiting one end of the longitudinal return spring and a transverse limiting plate for limiting one end of the transverse return spring.

[0011] Furthermore, a limiting component is provided between the floating platform and the lifting platform. The limiting component includes a limiting shaft that passes through a limiting hole on the floating platform and is connected to the lifting platform, and a limiting plate that is connected to the bottom of the limiting shaft and located on the top surface of the floating platform.

[0012] Furthermore, the limiting plate is circular, and the floating platform is provided with a receiving groove for accommodating the limiting plate.

[0013] Furthermore, a positioning component is provided between the floating platform and the lifting platform. The positioning component includes a first positioning sleeve fixed on the floating platform, a first positioning rod disposed on the lifting platform and arranged laterally along the lifting platform, and a first positioning drive component that drives the first positioning rod to enter or leave the first positioning sleeve.

[0014] Furthermore, the positioning component also includes a second positioning sleeve fixed on the floating platform, a second positioning rod disposed on the lifting platform and arranged longitudinally along the lifting platform, and a second positioning drive component for driving the second positioning rod into or out of the second positioning sleeve.

[0015] Furthermore, the lifting platform is provided with a first guide sleeve for guiding the first positioning rod and a second guide sleeve for guiding the second positioning rod.

[0016] The beneficial effects of this utility model are: 1. Using a universal ball as support and a spring for reset, the lifting platform can move arbitrarily within a preset range on the floating platform without producing a horizontal height difference, thus ensuring positioning accuracy during battery swapping; 2. A limit component is set to prevent the lifting platform from tilting due to the shift of the center of gravity during battery transfer; 3.

Detailed Implementation

[0022] See appendix Figure 1-4 This utility model provides a floating positioning component for battery swapping equipment, disposed between a floating platform 1 and a lifting platform 2. It includes a floating platform support component that supports the floating platform 1 to move arbitrarily within a preset range on the lifting platform 2 under the positioning constraint force generated by the positioning device on the floating platform 1 positioning the vehicle body or battery on the vehicle, and a return spring component that resets the floating platform 1 to its original position after the positioning constraint force is released. The floating platform 1 is equipped with a positioning device. When a positioning error occurs during the positioning process of removing or installing a battery from a new energy vehicle, the floating platform 1 can move arbitrarily within a preset range on the lifting platform 2 under the positioning constraint force generated during positioning, overcoming the reset force of the return spring component. This allows it to move to a fully positioned position to ensure the smooth progress of battery removal and installation operations. After the battery removal and installation operations are completed, the return spring component drives the floating platform 1 to move back to its initial position.

[0023] See appendix Figure 2-4At least two sets of floating platform support components are arranged along the width direction of the floating platform 1. Each set of floating platform support components includes multiple omnidirectional balls 3 arranged on the lifting platform 2 along the length direction of the lifting platform 2, and a support plate 4 fixed on the floating platform 1 and in contact with the multiple omnidirectional balls 3. The bottom area of ​​the support plate 4 is the preset movable range of the floating platform 1 on the lifting platform 2. In this embodiment, two sets of support components are arranged and located on both sides of the width direction of the lifting platform 2. The omnidirectional balls 3 can also be polytetrafluoroethylene (PTFE) blocks, utilizing the low coefficient of friction of PTFE blocks to facilitate relative movement between the PTFE blocks and the floating platform 1.

[0024] See appendix Figure 2-4 The system comprises multiple sets of reset spring assemblies. Each set includes at least one longitudinal reset spring 6 positioned between the floating platform 1 and the lifting platform 2, along the length of the lifting platform 2, and at least one transverse reset spring 5 positioned along the width of the lifting platform 2. The lifting platform 2 has a longitudinal mounting sleeve 8 for mounting the longitudinal reset spring 6 and a transverse mounting sleeve 7 for mounting the transverse reset spring 5. The floating platform 1 has a longitudinal limiting plate 10 for limiting one end of the longitudinal reset spring 6 and a transverse limiting plate 9 for limiting one end of the transverse reset spring 5. After installation, the two ends of the springs are respectively limited by the inner ends of the mounting sleeves and the limiting plates. The reset of the lifting platform 2 after the constraint force is released is achieved through the transverse and longitudinal springs and the multiple sets of reset spring assemblies. In this embodiment, four sets of reset spring assemblies are provided, with two sets at each end of the lifting platform 2, and the two sets of reset spring assemblies located at the same end of the lifting platform 2 are symmetrically arranged. Each set of reset spring assemblies contains three transverse reset springs 5 ​​and three longitudinal reset springs 6.

[0025] See appendix Figure 1-3 To prevent the floating platform 1 from tilting relative to the lifting platform 2 due to changes in the center of gravity during battery transfer, a limiting component is provided between the floating platform 1 and the lifting platform 2. The limiting component includes a limiting shaft 11 passing through a limiting hole 1-1 on the floating platform 1 and connected to the lifting platform 2, and a limiting plate 12 connected to the bottom of the limiting shaft 11 and located on the top surface of the floating platform 1. The limiting plate 12 is circular, and a receiving groove 1-2 is provided on the floating platform 1 to accommodate the limiting plate 12. The receiving groove 1-2 is circular with a diameter larger than the diameter of the limiting plate 12, and the diameter of the limiting hole 1-1 is larger than the diameter of the limiting shaft 11, so as not to affect the relative movement of the floating platform 1 and the lifting platform 2. In this embodiment, two sets of the above-mentioned limiting component are provided.

[0026] See appendix Figure 3 and 4A positioning assembly is provided between the floating platform 1 and the lifting platform 2 to prevent relative movement between the lifting platform 2 and the floating platform 1 during battery lifting, transfer, etc. The positioning assembly includes a first positioning sleeve 13 fixed to the floating platform 1, a first positioning rod 14 fixed to the lifting platform 2 and arranged laterally along the lifting platform 2, and a first positioning drive component 15 that drives the first positioning rod 14 into or out of the first positioning sleeve 13. Furthermore, the positioning assembly may also include a second positioning sleeve 16 fixed to the floating platform 1, a second positioning rod 17 fixed to the lifting platform 2 and arranged longitudinally along the lifting platform 2, and a second positioning drive component 18 that drives the second positioning rod 17 into or out of the second positioning sleeve 16. A first guide sleeve 19 for guiding the first positioning rod 14 and a second guide sleeve 20 for guiding the second positioning rod 17 are provided on the lifting platform 2. In this embodiment, both positioning drive components are electric push rods, with their ends hinged to the lifting platform 2 and the positioning rod, respectively. The aforementioned positioning components are set at one or both ends of the floating platform 1: when set at one end, positioning is required in both directions, so a positioning component that can achieve positioning in both directions is set; when set at both ends, positioning components that can achieve positioning in both directions can be set at both ends, or a positioning component that can achieve horizontal or vertical positioning can be set at one end, and a positioning component that can achieve vertical and / or horizontal positioning can be set at the other end.

[0027] In specific implementation of this utility model, when the battery is disassembled or installed, the positioning rod in the positioning assembly leaves the corresponding positioning sleeve so that the positioning device on the floating platform 1 can position the vehicle body and the battery or the vehicle body. When there is a positioning error during the positioning process and a positioning constraint force is generated, the floating platform 1 can overcome the reset force of the reset spring assembly and move within a preset range on the lifting platform 2 to achieve complete positioning, so as to ensure the smooth disassembly and installation of the battery.

[0028] After the battery is removed or installed and the positioning device leaves the vehicle body, the floating platform 1 moves to its initial position under the restoring force of the return spring assembly. The positioning rod in the positioning assembly enters the corresponding positioning sleeve to achieve positioning between the floating platform 1 and the lifting platform 2, so as not to affect the subsequent lifting, lateral and other operations of the battery swapping equipment.
