[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0027] Example 1:

[0028] This embodiment provides a car steering gear housing, including:

[0029] Main body 1, which is a cylindrical structure;

[0030] Mounting part 2, which is provided on both ends of the main body 1 for connecting the steering tie rod;

[0031] The connecting groove 3 is a ring-shaped structure and is provided on the periphery of the mounting part 2 for connecting the end of the dust cover 6.

[0032] Several snap-fit ​​pieces 4 are disposed on the mounting part 2. Each snap-fit ​​piece 4 includes a connecting block 41 and a pressing block 42. The connecting block 41 is hinged to the connecting groove 3. The pressing block 42 is installed on the end of the connecting block 41 near the connecting groove 3 and is used to press the end of the dust cover 6 into the connecting groove 3.

[0033] In this technical solution, when the automotive steering gear housing is in use, steering tie rods are installed on the two mounting parts 2 of the automotive steering gear housing, and dust covers 6 are installed at the connection points for protection. The dust cover 6 is made of rubber, with one end fixed to the steering tie rod and the other end fitted onto the connecting groove 3. The snap-fit ​​part 4 on the mounting part 2 consists of a connecting block 41 and a pressing block 42. The connecting block 41 is hinged to the connecting groove 3, and the pressing block 42 is installed on the end of the connecting block 41 near the connecting groove 3. By rotating the connecting block 41, the pressing block 42 moves into the connecting groove 3, and the end of the pressing block 42 abuts against the dust cover 6, pressing the dust cover 6 against the groove wall of the connecting groove 3, thus completing the connection between the dust cover 6 and the automotive steering gear housing.

[0034] Furthermore, several snap-fit ​​pieces 4 are arranged in a ring array on the mounting part 2 along the central axis of the main body 1. Through this structural design, the connection between the housing mounting part 2 and the dust cover 6 can be further strengthened by using multiple snap-fit ​​pieces 4, which is highly practical.

[0035] In summary, by opening connecting grooves 3 and snap-fit ​​parts 4 in the two mounting parts 2 of the automotive steering gear housing, the dust cover 6 can be fitted onto the mounting part 2 using the connecting grooves 3. The connecting block 41 of the snap-fit ​​part 4 is hinged to the connecting groove 3. By rotating the connecting block 41, the pressing block 42 is driven to squeeze the dust cover 6, so that the dust cover 6 is pressed and fixed in the connecting groove 3, thereby achieving a stable connection between the dust cover 6 and the automotive steering gear housing, and the operation is convenient.

[0036] Example 2:

[0037] This embodiment provides an automotive steering gear housing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] Furthermore, the clamping block 42 also includes:

[0039] Several protrusions 43 are provided on the end face of the clamping block 42 for abutting against the dust cover 6.

[0040] In this technical solution, by setting a number of protrusions 43, the contact area between the pressing block 42 and the dust cover 6 is increased when the pressing block 42 squeezes the dust cover 6, thereby increasing the friction between the pressing block 42 and the dust cover 6, and making the contact between the pressing block 42 and the dust cover 6 more stable, effectively improving the connection between the dust cover 6 and the car steering gear housing.

[0041] Example 3:

[0042] This embodiment provides an automotive steering gear housing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] Furthermore, the clamping block 42 is arc-shaped, and both ends of the clamping block 42 are provided with recessed holes 44.

[0044] This structural design ensures that when the clamping block 42 is positioned inside the connecting groove 3 and abuts against the dust cover 6, the clamping block 42 will not protrude above the top of the connecting groove 3. This reduces the risk of the clamping block 42 colliding with external objects, thereby preventing the clamping block 42 from being damaged by external impacts and effectively extending its service life.

[0045] Example 4:

[0046] This embodiment provides an automotive steering gear housing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] Furthermore, it also includes:

[0048] Several elastic snap-fit ​​pieces 5 are disposed in the connecting groove 3, and the ends of the elastic snap-fit ​​pieces 5 abut against the inner wall of the connecting groove 3.

[0049] In this technical solution, the elastic snap-fit ​​piece 5 is made of metal with a certain degree of elasticity. The elastic snap-fit ​​piece 5 is integrally connected in the connecting groove 3 and is set near the bottom of the connecting groove 3. When the dust cover 6 is installed, the worker puts the dust cover 6 into the connecting groove 3 and squeezes the end of the elastic snap-fit ​​piece 5. After the dust cover 6 is put on, the worker releases his grip, and the elastic snap-fit ​​piece 5 returns to its original position. The end of the elastic snap-fit ​​piece 5 will abut the dust cover 6 against the groove wall of the connecting groove 3, so that the dust cover 6 can be firmly put on the mounting part 2, improving the connection stability.

[0050] Furthermore, several elastic snap-fit ​​pieces 5 are arranged in a ring array within the connecting groove 3 along the central axis of the main body 1. This structural design further enhances the stability of the connection between the dust cover 6 and the mounting part 2.

[0051] Example 5:

[0052] This embodiment provides an automotive steering gear housing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] Furthermore, the elastic snap-fit ​​piece 5 and the connecting block 41 are respectively disposed on two opposite groove walls of the connecting groove 3.

[0054] In this technical solution, after the end of the dust cover 6 is installed and connected in the connecting groove 3, it will be as follows: Figure 3 As shown, the end of the dust cover 6 is S-shaped, and the elastic snap-fit ​​piece 5 and the clamping block 42 also play a certain clamping role on the dust cover 6, thereby further enhancing the connection between the dust cover 6 and the mounting part 2, and making it highly practical.

[0055] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
