Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle battery replacement, and in particular to a new energy vehicle battery loading and unloading auxiliary device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] The more common new energy vehicles mainly use electricity as the vehicle energy source. The battery module, electrical system, thermal management system and BMS are packaged in a shell to form the main body of the power battery system, which is usually located at the bottom of the frame and is large in size. When the battery of the new energy vehicle needs to be replaced or repaired, the new energy vehicle needs to be lifted before it can be disassembled.

[0004] As for the existing new energy vehicle battery disassembly process, the disassembly process uses a car lift that is often used in traditional fuel vehicles. Unlike electric vehicles, the chassis structure and layout of fuel vehicles are different. There is no large battery like that required for electric vehicles at the bottom of the fuel vehicle. After a simple lift, the fuel vehicle can be repaired directly under the vehicle. For electric vehicles, the damage and repair of the power supply module requires the entire vehicle to be lifted, and then the battery and related components at the bottom of the vehicle body are removed before repair. The battery, as the power supply source of the vehicle, is so large and heavy that it is not something that an ordinary person can lift and bear. The battery module as a whole may suddenly fall during the disassembly process, and there are serious safety hazards when maintenance personnel stand under the vehicle to disassemble. The process of removing the battery is often accompanied by the need for additional auxiliary support for the battery, which leads to the use of existing car lifts for battery repairs of such new energy vehicles. It is difficult and inconvenient to use. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention. Example 1

[0026] A new energy vehicle battery loading and unloading auxiliary device, such as Figure 1-Figure 3 As shown, it includes a load-bearing body 1, a fixed top plate 1a, a reduction motor 2, a load-bearing slider 3, a telescopic load-bearing support arm 4, a guide rod 5, a placement bracket 6 and a limit piece 7. The load-bearing body 1 is symmetrically fixed to the bottom of the left and right sides of the fixed top plate 1a by bolts. The load-bearing body 1 is used as a main load-bearing column. The reduction motor 2 is installed on the load-bearing body 1 on both sides. The load-bearing body 1 is connected with a screw rod for rotation. The load-bearing slider 3 is longitudinally slidably connected to the load-bearing body 1 and is threadedly connected to the screw rod. The reduction motor 2 drives the screw rod to rotate so that the load-bearing slider 3 is raised and lowered. The front and rear sides of the load-bearing slider 3 are hinged with the telescopic load-bearing support arm 4. The movable arm of the telescopic load-bearing support arm 4 is threadedly connected with a friction pad, which will not slip after contacting the underframe, thereby helping to improve stability. The load-bearing slider 3 is slidably connected to the guide rod 5 in a longitudinal sliding manner. The guide rods 5 on the left and right sides are jointly fixed to the placement bracket 6. The load-bearing slider 3 is slidably connected to the limit piece 7. A hole is opened on the guide rod 5, and the limit piece 7 is slidably fitted with the hole.

[0027] like Figure 1 and Figure 3 As shown, the limiting member 7 is composed of an N-shaped frame 71 and a limiting rod 72. The load-bearing slider 3 is slidably connected to the N-shaped frame 71, and the limiting rod 72 is fixed to the N-shaped frame 71. The limiting rod 72 is slidably fitted with the hole on the guide rod 5. In the initial state, after the limiting rod 72 is inserted into the hole of the guide rod 5, the bracket 6 is placed close to the bottom of the vehicle. After the vehicle body is lifted and the limiting rod 72 is pulled apart from the hole of the guide rod 5, the bracket 6 slides down and can be pulled farther away from the bottom of the vehicle.

[0028] like Figure 1 and Figure 4As shown, it also includes a pushing component 8, and the pushing component 8 is arranged on the load-bearing body 1; the pushing component 8 includes a first connecting plate 81, a push rod 82, a second connecting plate 83, a sliding plate 84 and a first spring 85, the sliding plate 84 is symmetrically slidably connected to the bottom of the fixed top plate 1a, and the sliding plates 84 on both sides are jointly fixed to the first spring 85, and the first spring 85 is used to keep the sliding plates 84 on the front and rear sides away from each other, and the push rod 82 is slidably connected to the load-bearing body 1 in a horizontal left and right sliding manner, and the first connecting plate 81 and the second connecting plate 83 are movably connected to the push rod 82 respectively, the first connecting plate 81 is hinged to the sliding plate 84, and the second connecting plate 83 is slidably hinged to the telescopic load-bearing support arm 4.

[0029] like Figure 1 and Figure 5 As shown, it also includes a pulling component 9, and the pulling component 9 is arranged on the fixed top plate 1a; the pulling component 9 includes a dual-axis motor 91, a winding wheel 92 and a pull rope 93, the dual-axis motor 91 is installed on the fixed top plate 1a, the winding wheel 92 is fixedly connected to the output shaft of the dual-axis motor 91, one end of the pull rope 93 is fixedly connected to the winding wheel 92, and the other ends of the pull ropes 93 on both sides are respectively fixedly connected to the sliding plates 84 on both sides.

[0030] When in use, the load-bearing body 1 is installed in a fixed place. After it is stabilized, the new energy vehicle is driven between the two load-bearing bodies 1. At this time, the placement bracket 6 is located at the bottom of the vehicle, and the winding wheel 92 is driven by the dual-axis motor 91 to rotate and rotate the winding rope 93, thereby pulling the sliding plates 84 closer to each other, and the movement of the sliding plates 84 makes the first connecting plate 81 tilt and pull the push rod 82, and the push rods 82 on the left and right sides slide closer to each other, so that the second connecting plate 83 pushes the telescopic load-bearing support arm 4 to rotate, and the telescopic load-bearing support arm 4 is extended into the bottom of the vehicle and located under the frame. At this time, the load-bearing slider 3 can be driven to move up by the reduction motor 2, and the telescopic load-bearing support arm 4 follows the load-bearing slider 3. The heavy slide block 3 moves up and lifts the new energy vehicle, and the placement bracket 6 moves up with it at this time. After the new energy vehicle rises to a certain height, it can stop, and then the battery module under the vehicle can be disassembled. After the battery module is disassembled, the battery module can be directly supported by the placement bracket 6, and then the limit piece 7 is pulled out to release the sliding restriction on the guide rod 5, and the placement bracket 6 slides down a distance to increase the distance between the battery module and the vehicle body, and then the reduction motor 2 can be slowly lowered to a suitable height, and then the battery module can be removed. In this way, the safety of maintenance personnel can be effectively protected during the disassembly of the new energy battery. Example 2

The N-shaped frame 71 is in sliding contact, and as the load-bearing slider 3 continues to move upward, the wedge-shaped push plate 102 will eventually contact the N-shaped frame 71 and push the N-shaped frame 71 to slide, thereby causing the limit rod 72 to slide out of the hole in the guide rod 5, thereby releasing the sliding restriction on the guide rod 5. As the load-bearing slider 3 descends, the placement bracket 6 first contacts the ground until the load-bearing slider 3 contacts the ground, and the hole in the guide rod 5 is realigned with the limit rod 72, allowing the limit rod 72 to penetrate into the hole again.

[0032] like Figure 1 and Figure 7 As shown, it also includes a marking component 11, and the marking component 11 is set on the fixed top plate 1a; the marking component 11 includes an extension frame 111 and an identification plate 112, the extension frame 111 is welded on the fixed top plate 1a, and the identification plate 112 is fixedly connected to the lower part of the extension frame 111. When the new energy vehicle moves in, the identification plate 112 can be used as a reference to align the sliding extension position of the telescopic load-bearing arm 4.

[0033] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a blocking component 12, and the blocking component 12 is arranged on the placement bracket 6; the blocking component 12 includes an extension plate 121, a blocking plate 122, a limiting plug rod 123 and a third spring 124, the extension plate 121 is welded symmetrically front and back on the placement bracket 6, the extension plate 121 is slidably connected to the blocking plate 122, the blocking plate 124 can limit the battery module from sliding back and forth and falling off on the placement bracket 6, and ensure the stability of the battery module, the limiting plug rod 123 is slidably connected to the blocking plate 122, and a third spring 124 is arranged between the limiting plug rod 123 and the blocking plate 122, and limiting holes 125 are evenly opened on the extension plate 121, the third spring 124 is used to keep the limiting plug rod 123 tightly inserted in the limiting hole 125 and will not fall off, and the limiting plug rod 123 can be inserted into different limiting holes 125 to adjust different spacing sizes to adapt to different battery modules.
