DETAILED DESCRIPTION

[0031] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0033] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships recorded in the embodiments and shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0034] like Figure 1-Figure 6 As shown, the utility model specifically relates to a lifting mechanism based on battery replacement of new energy vehicles, including:

[0035] The RGV walking layer 100 assembly includes a bearing bracket 110, wherein the bearing bracket 110 is disposed on the track 500 via walking wheels and can move linearly along the length direction of the track 500;

[0036] The fixed layer assembly 300 includes a fixed bracket 310, and the fixed bracket 310 is connected to the RGV walking layer 100 assembly through a scissor fork assembly 200;

[0037] The floating layer assembly 400 includes a floating bracket 410, which is mounted above the fixed layer assembly 300 and is provided with a plurality of vehicle body locating pins 440, a battery support block 460, a battery pack locating pin 430 and a locking and unlocking gun 420;

[0038] The vehicle further includes a lifting assembly 120 disposed on the supporting bracket 110 . The lifting assembly 120 can drive the fixed layer assembly 300 to move and drive the floating layer assembly 400 to abut against the bottom of the vehicle body so as to quickly replace the battery pack.

[0039] It should be noted that, the floating bracket 410 is assembled on the fixed bracket 310, and the fixed bracket 310 is connected to the supporting bracket 110 through the scissor fork assembly 200. The lifting assembly 120 located on the supporting bracket 110 can drive the vertical up and down movement between the fixed brackets, which not only supports the fixed bracket 310 through the scissor fork assembly 200, but also ensures that the fixed bracket 310 is smoother in the process of moving up and down.

[0040] Among them, the function and use method of the scissor fork assembly 200 belong to the prior art, and those skilled in the art can easily deduce its function by combining with the drawings, so it will not be described in detail.

[0041] In addition, since the floating bracket 410 is assembled on the fixed bracket 310, when the fixed bracket 310 moves, it drives the floating bracket 410 to move, so that the vehicle body positioning pin 440 located on the floating bracket 410 abuts against and is positioned at the bottom of the vehicle, and at the same time, the battery support block 460 located on the floating bracket 410 abuts against the battery pack at the bottom of the vehicle, and the battery pack positioning pin 430 is positioned with the battery pack, and the bolts of the battery pack are unlocked by the unlocking gun 420 to complete the disassembly of the battery pack.

[0042] During this process, the floating bracket 410 abuts against the bottom of the vehicle, and the fixed bracket 310 also abuts against the bottom of the vehicle.

[0043] Furthermore, when the battery pack is disassembled, the fixed bracket 310 and the floating bracket 410 move vertically downward and move linearly relative to the guide rail through the running wheels provided on the supporting bracket 110 to move the battery pack out and replace it.

[0044] like Figure 2-Figure 4 As shown, an L-shaped connecting block 341 is provided at the bottom of the floating bracket 410, and the L-shaped connecting block 341 is connected to the fixed bracket 310 through a hanging chain 340. Such a configuration allows the floating bracket 410 to be movable relative to the fixed bracket 310, and adopts a movable assembly method, so that the locking and unlocking gun 420 can better disassemble or assemble the bolts of the battery pack, reduce errors in the assembly or disassembly process, and thus improve work efficiency.

[0045] Furthermore, the suspension chain 340 is used to prevent the floating bracket 410 from falling off, and the floating bracket 410 can actually only move within a small range.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, a plurality of positioning rods 450 are provided at the bottom of the floating bracket 410 , and a positioning groove 111 for cooperating with the positioning rods 450 is provided at the end of the fixed bracket 310 . The plurality of positioning rods 450 pass through the fixed bracket 310 and are connected to the positioning groove 111 .

[0047] The positioning rod 450 and the positioning groove 111 cooperate with each other to limit the lowest position of the fixed bracket 310 when it is lowered, so as to support and position the fixed bracket 310 and prevent the fixed bracket 310 from moving.

[0048] like Figure 1 and Figure 5As shown, the scissor fork assembly 200 includes a first cross arm and a second cross arm, the first cross arm and the second cross arm are arranged opposite to each other, and the structure of the first cross arm is the same as the structure of the second cross arm.

[0049] The first cross arm includes a support arm 1 210 and a support arm 220, one end of the support arm 1 210 is movably connected to the bearing bracket 110, and the other end of the support arm 1 210 is connected to the fixed bracket 310 through a linear module 230;

[0050] One end of the second support arm 220 is movably connected to the fixed bracket 310 , and the other end of the second support arm 220 is connected to the supporting bracket 110 via a linear module 230 .

[0051] In this embodiment, the scissor fork assembly 200 is further described, but since it is a conventional method in the prior art, it will not be described in detail.

[0052] like Figure 1 and Figure 6 As shown, it also includes a servo motor 130 arranged on the supporting bracket 110, and a rack 510 is arranged parallel to the inner side of the track 500. The servo motor 130 is meshed with the rack 510 through a gear and can drive the RGV walking layer 100 to move linearly.

[0053] The lifting assembly 120 includes a driving motor 121, a reversing reducer 122 and two sets of rigid chains 123. The bottom of the fixed bracket 310 is provided with an abutment block used in conjunction with the rigid chain 123. When the rigid chain 123 is started and abuts against the abutment block, it can drive the fixed bracket 310 to move vertically up and down.

[0054] Among them, the rigid chain 123 is a new type of mechanical component for vertically lifting loads or load-bearing platforms, which can withstand tension and pressure. The rigid chain 123 abuts against the bottom of the fixed bracket 310 to support the fixed bracket 310; in addition, since the fixed bracket 310 is connected to the load-bearing bracket 110 through a cross arm, when the rigid chain 123 abuts against the fixed bracket 310 and retracts, it can drive the fixed bracket 310 to move up and down.

[0055] like Figure 1-Figure 4 As shown, the fixed bracket 310 is provided with a plurality of positioning posts 330 , and the floating bracket 410 is provided with a through slot 411 used in conjunction with the positioning posts 330 .

[0056] The positioning column 330 and the through slot 411 cooperate with each other to position the floating bracket 410, limit the moving range of the floating bracket 410, and avoid collision with other components assembled on the floating bracket 410.

[0057] The fixing bracket 310 is provided with a plurality of vehicle lifting devices 320 , and the vehicle lifting devices 320 include a support pad movably connected to the fixing bracket 310 and a lifting motor, and the lifting motor can drive the support pad to move vertically up and down to lift the vehicle.

[0058] The vehicle lifting device 320 disposed on the fixed layer assembly 300 can lift the vehicle again by a certain distance, so as to separate the vehicle and the battery pack, and can be applied to vehicles of different models.

[0059] 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.
