Description
Technical Field
[0001] This utility model relates to the field of electric bus battery replacement technology, and in particular to a battery box replacement tool for new energy buses. Background Technology
[0002] In recent years, the new energy vehicle market has shown a rapid development trend, with new energy battery vehicles gradually becoming an important force in the automotive market, and production, sales, and ownership all growing rapidly. In terms of power type, pure electric new energy vehicles are the mainstream development direction for new energy vehicles in China. As new energy buses age, their power batteries degrade, creating an urgent need for replacement. Battery swapping for buses has become the optimal choice for bus operation, while directly reducing costs for bus companies.
[0003] Existing bus power batteries are typically heavy and bulky, requiring specialized lifting equipment and tools for handling and installation. This also places high demands on the physical strength and operational skills of the operators. During loading and unloading, care must be taken to avoid personal injury or equipment damage due to the excessive weight of the batteries. The limited interior space of buses and the narrow operating space make it difficult to disassemble and assemble power battery packs, resulting in extremely low installation efficiency. Replacing the power battery packs with new ones can also easily damage them. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the existing technology where the power batteries of buses are usually heavy and bulky, requiring specialized lifting equipment and tools for handling and installation. At the same time, it also requires high physical strength and operating skills from the operators. During loading and unloading, care must be taken to avoid personal injury or equipment damage due to the excessive weight of the battery. The limited internal space of the bus and the narrow operating space make it difficult to disassemble and assemble the power battery pack, resulting in extremely low installation efficiency and a greater risk of damage to the power battery pack when replacing it. Therefore, this utility model proposes a new energy bus battery box replacement tool.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery box replacement tool for a new energy bus, comprising a replacement tool structure, wherein the replacement tool structure comprises an aluminum-magnesium plate, and multiple bullseye wheel bodies are distributed on the upper and lower surfaces of the aluminum-magnesium plate, and ball bearings are movably installed inside the bullseye wheel bodies.
[0006] Preferably, a pusher buckle is symmetrically installed on one end of the aluminum-magnesium plate, and a pusher is movably connected to the outer side of the pusher buckle.
[0007] Preferably, the diameter of the ball bearing is 12mm.
[0008] Preferably, both the aluminum-magnesium plate and the bullseye wheel body are provided with multiple bolt holes.
[0009] Preferably, the aluminum-magnesium plate has dimensions of 930mm × 569mm × 37mm.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] In this invention, bullseye wheel bodies are provided on both the upper and lower surfaces of the aluminum-magnesium plate. By using bolts to penetrate the bolt holes, it is easy to install the ball bearings on the aluminum-magnesium plate. After removing the fixing screws of the power battery pack to be replaced, one end of the battery pack is pried up with a tool, and the aluminum-magnesium plate is placed between the battery pack and the vehicle body. The power battery pack can then be easily pulled out. The power battery pack to be installed is placed on the aluminum-magnesium plate, and the mounting holes can be moved 360 degrees within the battery compartment. Once the mounting holes are successfully located, the aluminum-magnesium plate can be pulled out to complete the installation. This significantly shortens the battery swapping time, improves the operating efficiency of electric buses, reduces bus downtime, and ensures stability when carrying the battery. It effectively avoids the risk of battery slippage and damage during transportation and installation, ensuring the safety of operators and equipment. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a battery box replacement tool for a new energy bus, including a replacement tool structure 1. The replacement tool structure 1 includes an aluminum-magnesium plate 106. Multiple bullseye wheel bodies 104 are distributed on the upper and lower surfaces of the aluminum-magnesium plate 106. Ball bearings 105 are movably installed inside the bullseye wheel bodies 104. Push handle buckles 102 are symmetrically installed on one end of the aluminum-magnesium plate 106. Push handles 101 are movably connected to the outside of the push handle buckles 102. The diameter of the ball bearings 105 is 12mm. Multiple bolt holes 103 are opened on both the aluminum-magnesium plate 106 and the bullseye wheel bodies 104. The dimensions of the aluminum-magnesium plate 106 are 930mm × 569mm × 37mm.
[0020] In this embodiment, bullseye wheel bodies 104 are provided on both the upper and lower surfaces of the aluminum-magnesium plate 106. Bolts are inserted through bolt holes 103 to facilitate the mounting of ball bearings 105 onto the aluminum-magnesium plate 106. The height of the bullseye wheel bodies 104 is between 35-39 mm, and each bullseye wheel body 104 can bear a weight of 10 kg. Each side of the aluminum-magnesium plate 106 has 42 bullseye wheel bodies 104, which can easily support a weight of 300 kg. Furthermore, the dimensions of the aluminum-magnesium plate 106 conform to national standard battery boxes, making it suitable for most electric bus battery boxes. It can move easily 360 degrees in confined spaces, exhibiting broad versatility and application prospects. The flexible rolling of the ball bearings 105 allows for the smooth sliding of work plates, material boxes, and other objects running on it, reducing the labor intensity of workers, facilitating timely problem detection and handling by maintenance personnel, and lowering the difficulty of equipment maintenance. During replacement, the moving parts that need to be replaced can be easily moved... After removing the battery pack fixing screws, use a tool to pry up one end of the battery pack.

After successful positioning, pull out the aluminum-magnesium plate 106 to complete the installation. This significantly shortens the battery swapping time, improves the operating efficiency of electric buses, reduces bus downtime, and ensures the stability when carrying the battery. It effectively avoids the risk of battery slippage and damage during transportation and installation, and ensures the safety of operators and equipment.
[0021] The working principle of this embodiment is as follows: In use, a bolt is first inserted through the bolt hole 103 to facilitate the installation of the ball bearing 105 on the aluminum-magnesium plate 106. Both the upper and lower surfaces of the aluminum-magnesium plate 106 are provided with bullseye wheel bodies 104. When replacing, the fixing screws of the power battery pack to be replaced are removed, and one end of the battery pack is pried up with a tool. The aluminum-magnesium plate 106 is placed between the battery pack and the vehicle body, and the power battery pack can be easily pulled out. The power battery pack to be installed is placed on the aluminum-magnesium plate 106, and the fixing hole position can be found by moving 360 degrees in the battery compartment. After successful positioning, the aluminum-magnesium plate 106 is pulled out to complete the installation, which significantly shortens the battery swapping time and improves the operating efficiency of electric buses.
