[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please see attached Figure 1 - Attachment Figure 2 The utility model provides an embodiment: a combined automobile chassis rear axle housing, including a diamond-shaped shell 1, a circular hole 14 is opened in the middle of the front and rear sides of the diamond-shaped shell 1, a sealing gasket 15 is fixedly connected to the inner side of the circular hole 14, a sealing cover 9 is attached to the outer side of the sealing gasket 15, and a bolt 10 is threadedly connected to the outer wall of the sealing cover 9 around the outer wall, and the inner end of the bolt 10 is threadedly connected to the outer wall of the diamond-shaped shell 1 of the circular hole 14, and a threaded hole 13 is opened at the left and right ends of the rear side of the diamond-shaped shell 1, and a column plug 11 is arranged on the inner side of the threaded hole 13. The outer wall of the column plug 11 is opened with a threaded groove 12, and the outer wall of the threaded groove 12 is threadedly connected to the inner side of the threaded hole 13, and a protective mechanism 2 is arranged at the bottom end of the diamond-shaped shell 1, and a mounting member 4 is fixedly connected to the left and right ends of the front side of the diamond-shaped shell 1;

[0030] Specifically, the design of the diamond-shaped shell 1 takes into account the integrity and sealing of the structure. In order to achieve these functions, a sealing gasket 15 is fixedly connected to the inner side of each circular hole 14. The function of this sealing gasket 15 is to fill the gap between the circular hole 14 and the external component to prevent liquid or gas leakage, thereby improving the sealing performance of the entire structure. The outer wall of the sealing cover 9 is designed to be threaded and fastened to the diamond-shaped shell 1 by bolts 10. The inward end of these bolts 10 is connected to the thread on the outer wall of the diamond-shaped shell 1 around the circular hole 14, forming a solid connection structure.

[0031] Please see attached Figure 3 The protection mechanism 2 includes a spring 201, the top of the spring 201 is fixedly connected to the bottom of the diamond-shaped housing 1, the other end of the spring 201 is fixedly connected to a conical protection plate 205, the left and right sides of the inside of the conical protection plate 205 are fixedly connected to a long block 202, the bottom end of the conical protection plate 205 is fixedly connected to a conical protection plate 1 203, the bottom surface of the conical protection plate 1 203 is fixedly connected to a long strip 204, and the left and right sides of the top of the diamond-shaped housing 1 are fixedly connected to a mounting member 2 5;

[0032] Specifically, the spring 201 plays a key supporting and buffering role. The top of the spring 201 is fixedly connected to the bottom of the diamond-shaped shell 1. This design ensures that the spring 201 can remain stable when under pressure, and also provides the necessary elasticity for the entire structure. The conical protective plate 205 is not only an integral part of the entire structure, but its unique shape helps to disperse external impact forces, thereby protecting internal components from damage. The bottom end of the conical protective plate 205 is fixedly connected to the conical protective plate 1 203, and the conical protective plate 1 203 also has a protective function.

[0033] Please see attached Figure 1 - Attachment Figure 2 The left and right sides of the diamond-shaped shell 1 are fixedly connected with a long plate 8, the outward side of the long plate 8 is rotatably connected with a rotating shaft 7, the outer wall of the rotating shaft 7 is fixedly connected with a protective strip 6, the top ends of the front and rear sides of the diamond-shaped shell 1 are fixedly connected with a fluorescent sticker 16, and the top end of the diamond-shaped shell 1 is fixedly connected with a top plate 3;

[0034] Specifically, the rotating shaft 7 is flexibly rotated through the design device, and a protective strip 6 is fixedly connected to the outer wall of the rotating shaft 7. The protective strip 6 may be used to provide protection to prevent the rotating shaft 7 from being affected or damaged by the external environment. It may also be used to increase friction to make the operation of the rotating shaft 7 more stable and precise. The presence of the fluorescent sticker 16 may be for safety reasons, so that the diamond-shaped shell 1 can be easily identified in a dimly lit environment, thereby improving the safety of the user.

[0035] Working principle: When the rear axle housing of the chassis needs to be used, first put the sealing gasket 15 into the circular hole 14 opened on the diamond-shaped shell 1, then fit the sealing cover 9 with the sealing gasket 15, and then install the sealing cover 9 on the outer wall of the diamond-shaped shell 1 through the bolt 10, and finally pick up the cylindrical plug 11, cooperate with the threaded groove 12 to threadedly connect with the threaded hole 13 opened on the rear side of the diamond-shaped shell 1, so as to seal the threaded hole 13, thereby preventing dust, moisture and other pollutants from entering the rear axle housing, slowing down the wear of parts and extending the service life, and then fix the elongated strip 204 with the conical protective plate 1 203, and then fix it to the bottom end of the diamond-shaped shell 1 with the spring 201 and the elongated block 202, and then fix it with the conical protective plate 2 205, and finally fix the conical protective plate 1 203 with the conical protective plate 2 205, thereby effectively preventing stones from flying and colliding with the rear axle housing during driving, thereby affecting the service life.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
