[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] First Embodiment As attached Figure 1 To be continued Figure 4 As shown: An electric vehicle gearbox housing that is easy to fix and install includes a gearbox body 1 and rear axle housings 2 disposed on the left and right sides of the gearbox body 1. It also includes a connecting component 3 disposed outside the gearbox body 1, which includes multiple connecting rods 301 that are inserted into each rear axle housing 2 and the gearbox body 1. The connecting rods 301 can be used to connect the gearbox body 1 and the rear axle housings 2, thereby forming an initial positioning.

[0026] A quick-connect structure is provided on the outside of multiple connecting rods 301. The quick-connect structure includes a sector plate 302 fixedly connected to the other end of each group of connecting rods 301. Each sector plate 302 has a group of L-shaped plates 303 fixedly connected to its outer surface. The ends of each group of L-shaped plates 303 that are close to each other are connected by bolts 304. After the connecting rods 301 are installed, the sector plate 302 will drive the L-shaped plate 303 to be stabilized on the outside of the gearbox body 1. Then, the bolts 304 are used to connect them, thereby forming a tight and stable fastening of the L-shaped plate 303, further reducing the amount of bolts 304 used, thereby improving the installation efficiency of the gearbox body 1.

[0027] Each L-shaped plate 303 has a through groove 305 on one side. A connecting post 306 is slidably connected to the inner wall of each through groove 305. One end of each connecting post 306 is connected to the outer surface of the gearbox body 1. The other end of each gearbox body 1 is rotatably connected to a baffle 307. When the L-shaped plate 303 is stabilized outside the gearbox body 1, the through groove 305 will baffle 307, and then deflect the baffle 307 to make it perpendicular to the through groove 305, which further improves the firmness of the L-shaped plate 303. The sides of each group of L-shaped plates 303 that are close to each other are fixedly connected to a reinforcing plate 308. The reinforcing plate 308 can strengthen the connection between the L-shaped plates 303, further improving the firmness of the gearbox body 1 after the connection. Each L-shaped plate 303 has an anti-wear pad 309 fixedly connected to the side of each L-shaped plate 303 that is close to the gearbox body 1. The anti-wear pad 309 can prevent friction between the L-shaped plate 303 and the gearbox body 1.

[0028] Each sector plate 302 has a set of fastening holes 310 on the side away from the gearbox body 1. Each fastening hole 310 has a fastening post 311 inserted into its inner wall. The other end of each set of fastening posts 311 is fixedly connected to a fastening plate 312. When the sector plate 302 is stable, the fastening post 311 can be inserted into the fastening hole 310. The fastening plate 312 will pull on the fastening post 311, further strengthening the firmness between the sector plates 302.

[0029] Second Embodiment As attached Figure 1 Appendix Figure 5 With appendix Figure 6As shown: The shielding component 4 is disposed on the outside of each rear axle housing 2 and is used to shield and protect the connection between the gearbox body 1 and the rear axle housing 2. Each shielding component 4 includes a protective cover 401 sleeved on the outside of each rear axle housing 2. The protective cover 401 has a set of embedding grooves that are adapted to the size of the L-shaped plate 303 on the side near the gearbox body 1. After the gearbox body 1 and the rear axle housing 2 are connected, the protective cover 401 is pulled to be outside the connection between the rear axle housing 2 and the gearbox body 1, thereby forming a shield, which can effectively prevent mud and water from entering and further ensure the long-term stable operation of the connection between the gearbox body 1 and the rear axle housing 2.

[0030] Each protective cover 401 has a connecting frame 402 on one side, and a positioning plate 403 is slidably connected to the inner wall of each connecting frame 402. One end of each positioning plate 403 is connected to the outer surface of the protective cover 401. By sliding the positioning plate 403 outside the protective cover 401 into the connecting frame 402, the protective cover 401 is stabilized and its displacement can be prevented.

[0031] Each connecting frame 402 is slidably connected to a stop plate 404, and a movable plate 405 is fixedly connected to the back of each stop plate 404. Each movable plate 405 is slidably connected to a sliding post 406, and a spring 407 is sleeved on the outer surface of each sliding post 406. A circular plate 408 is fixedly connected to the top of each sliding post 406. The elasticity of the spring 407 can push the movable plate 405, and the stop plate 404 will slide into the connecting frame 402, thereby blocking the positioning plate 403 and preventing the positioning plate 403 from sliding out of the connecting frame 402.

[0032] Working principle: When installing the gearbox body 1, first align the mounting holes on the gearbox body 1 with the mounting holes on the rear axle housing 2. Then, fit the sector plate 302 onto the outside of the rear axle housing 2, insert the connecting rod 301 into the mounting hole on the rear axle housing 2 and extend it into the mounting hole on the gearbox body 1. At the same time, the L-shaped plate 303 will be outside the gearbox body 1. Then, use bolts 304 to connect the L-shaped plates 303 to complete the installation of the gearbox body 1. By reducing the number of bolts 304 tightened, the installation efficiency of the gearbox body 1 can be further improved.
