Description

Technical Field

[0001] The utility model relates to the technical application field of new energy vehicle battery replacement stations, and in particular to a vehicle lifting mechanism used in new energy vehicle battery replacement stations. Background Art

[0002] When the battery swap station is swapping batteries for electric vehicles, the RGV cart needs to cooperate with the lifting mechanism to lift the battery pack. That is, during the battery swap process, the RGV cart carries the battery pack and drives under the electric vehicle, and the lifting mechanism lifts the battery for battery swapping.

[0003] However, the traditional lifting mechanism has exposed lifting columns that occupy part of the space, which not only affects the appearance but also increases the overall width of the battery swap station, adding additional costs to the site selection and transportation of the entire battery swap station.

[0004] Therefore, there is an urgent need to provide a vehicle lifting mechanism that does not require digging on the ground for battery replacement and has a certain aesthetic appeal and is used in new energy vehicle battery replacement stations. Utility Model Content

[0032] like Figure 1-Figure 3 As shown, the utility model specifically relates to a vehicle lifting mechanism for a new energy vehicle battery swap station, including a bearing base 100 for facilitating vehicle travel, the bearing base 100 is provided with a lifting assembly, the lifting assembly is provided with two groups, and includes a left lifting assembly 220 provided on one side of the bearing base 100 and a right lifting assembly 210 provided on the other side of the bearing base 100;

[0033] The left lifting assembly 220 includes a gantry 211 fixed to the bearing base 100 and a bearing plate assembly connected to the gantry 211 via a linear moving module;

[0034] The supporting base 100 is provided with a movable guide rail 110 for the AGV to travel, and one end of the movable guide rail 110 is located below the supporting plate assembly, and the other end of the movable guide rail 110 is located on one side of the right lifting assembly 210; when the supporting plate assembly moves vertically upward through the linear moving module, the AGV moves along the length direction of the movable guide rail 110 and travels to the bottom of the vehicle to replace the battery pack for the vehicle.

[0035] It should be noted that the vehicle can travel on the carrying base 100. When the vehicle reaches a designated position of the carrying base 100, the left lifting assembly 220 and the right lifting assembly 210 located on opposite sides of the vehicle are activated to lift the vehicle.

[0036] The gantry 211 is fixed on the bearing base 100 to provide support for the bearing plate assembly. The linear moving module drives the bearing plate assembly to move vertically upward, and the bearing plate assembly abuts against the bottom of the vehicle to lift the vehicle.

[0037] The linear moving module is a mechanism that can drive the supporting plate assembly to move vertically upward, and can be a lifting cylinder, a lifting motor, etc. In this embodiment, a servo motor 212 and a chain 216 are combined. The supporting plate assembly is slidably arranged in the gantry 211, one end of the chain 216 is connected to the supporting plate assembly, and the other end of the chain 216 is connected to the servo motor 212. The servo motor 212 drives the supporting plate assembly to move vertically up and down through the chain 216.

[0038] After the vehicle is lifted, the AGV passes through the gantry 211 of the left lifting assembly 220 via the moving guide rail 110 and enters the supporting base 100, and moves to the bottom of the vehicle, and the vehicle battery pack is replaced by the AGV.

[0039] Among them, AGV is a commonly used configuration in the field of new energy vehicle battery swap stations. It has its own power system and can independently complete the disassembly and replacement of battery packs. It is a relatively mature technical means in this field, so it will not be described in detail.

[0040] The structure of the left lifting assembly 220 is the same as that of the right lifting assembly 210, and two sets of identical lifting assemblies are used to ensure stability during the vehicle lifting process.

[0041] The supporting plate assembly includes a cantilever bracket 217 connected to the linear moving module and a cover plate 218 of a supporting bracket assembled on the cantilever bracket 217. A positioning pin is provided at the bottom of the cover plate 218, and the cantilever bracket 217 is provided with a positioning hole used to cooperate with the positioning pin. The positioning pin is snap-connected with the positioning hole to complete the assembly of the cover plate 218.

[0042] Among them, the cantilever bracket 217 is slidably connected in the gantry 211, and the upper end of the cantilever bracket 217 is connected to the chain 216. The servo motor 212 assembled on the gantry 211 is connected to the chain 216 through the coupling 213, the rotating shaft 214 and the sprocket 215. The chain 216 is driven to rotate by the servo motor 212 to drive the cantilever bracket 217 to move vertically up and down along the height direction of the gantry 211.

[0043] In addition, the cantilever bracket 217 is an L-shaped structure, and a positioning hole is provided at the lateral surface end of the cantilever bracket 217. A positioning pin is provided on the cover plate 218. The cover plate 218 is assembled on the lateral surface end of the cantilever bracket 217 through the positioning pin and the positioning hole. This can provide good support for the bottom of the vehicle and facilitate the wheels to run on the cover plate 218.

[0044] The cover plate 218 is provided with a plurality of rollers 2181, which guide the wheels to ensure that the vehicle will not deviate when it reaches a designated position.

[0045] The bottom of the cover plate 218 is provided with a plurality of limiting support rods 2182 , which further support the cover plate 218 , thereby ensuring the relative levelness of the cover plate 218 and the supporting base 100 , and further ensuring the flatness of the wheels when running on the cover plate 218 .

[0046] The movable guide rail 110 is located inside the gantry 211 , and the AGV can pass through the gantry 211 along the length direction of the movable guide rail 110 and complete the disassembly or assembly of the battery pack, ensuring that the gantry 211 and the load-bearing plate assembly will not interfere with the AGV.

[0047] A rack 120 is disposed inside the movable guide rail 110 , and the AGV is provided with a gear matched with the rack 120 . The gear is meshed with the rack 120 , so that the AGV can move linearly on the movable guide rail 110 .

[0048] The coordination of the rack 120 and the gear provides power for the movement of the AGV through the servo motor 212 provided on the AGV. The moving guide rail 110 ensures the smooth movement of the AGV and guides the moving direction of the AGV.

[0049] A limit block 130 is provided at one end of the rack 120 close to the right lifting assembly 210. The limit block 130 limits the moving range of the AGV so that it can accurately reach the specified position and quickly disassemble or assemble the battery pack.

[0050] The bearing base 100 is provided with a lane gate 300 .

[0051] The left lifting assembly 220 and the right lifting assembly 210 are connected by a fixing rod, wherein the fixing rod is arranged between the two gantries 211, thereby further ensuring the stability of the gantries 211, and thus ensuring the stability of the vehicle during the lifting process.

[0052] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
