[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a mounting structure for upper and lower shields of a vehicle steering column, which can solve the problem that the contact edges of the upper and lower shields cannot be kept smooth and the visual effect is poor after the upper and lower shields are installed and matched.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] The invention discloses an installation structure of upper and lower guards of a vehicle steering column, comprising an upper guard and a lower guard installed in cooperation with the upper guard. The edge of the upper guard is provided with a concave hole column, and the edge of the lower guard is provided with a round latch column in cooperation with the concave hole column.

[0008] The design of the concave hole column and the round pin column can improve the matching relationship of the parts after installation, and the visual flatness after assembly can enhance the overall visual effect. In addition, the upper and lower shields are optimized from the conventional single z-axis limit to the x-axis limit, and the assembly effect of the upper and lower shield matching area is optimized, which reserves more safety margins for the mold, making it more convenient to fine-tune the margins later and faster to install.

[0009] When the upper and lower guards are closed, the upper latch is snap-connected with the lower latch, the upper auxiliary latch is snap-connected with the lower auxiliary latch, and the round latch column is located inside the concave hole column. In this way, the upper and lower guards are firmly fixed through three fixing methods, and the mold process is simple, and the connection between the upper and lower guards is smoother.

[0010] According to one embodiment of the utility model, the edges where the upper shield and the lower shield are installed together are provided with a plug-in card structure, and the plug-in card structure includes an upper auxiliary latch and a lower auxiliary latch. The upper auxiliary latch is a snap-in structure extending inward from the edge of the upper shield; the lower auxiliary latch is a sheet protruding inward from the edge of the lower shield, and the sheet and the snap-in structure cooperate with each other. The plug-in card structures are both located on the inner side of the upper shield and the lower shield. A spacing distance is provided between the plug-in card structure and the concave hole column and the circular latch column. The plug-in card structure also includes an upper latch and a lower latch, the upper latch is a plate extending downward from the inner side of the edge of the upper shield, and an arc-shaped notch is provided in the middle of the plate, and the lower latch is a column extending inward from the edge of the lower shield, and the diameter of the column close to the lower shield is smaller than the diameter of the side away from the lower shield.

[0011] Conventional clamping structures have complex mold structures, large local gaps, uneven surface differences, and it is difficult for the upper and lower shields to match smoothly. This structure can increase the functional strength of the parts by optimizing the clamping design. In addition, the conventional clamping structure has higher requirements on the production process of the injection mold due to its complex design structure, and the product defective rate will also be higher. This structure optimizes the clamping structure, thereby simplifying the structure of the corresponding injection mold, reducing the difficulty of processing the injection mold for the parts, and improving the production efficiency of the product.

[0012] In addition, the plug-in card connection structure includes two card connection methods. The upper auxiliary pin and the lower auxiliary pin are mainly used to limit the displacement in the z direction, while the upper pin and the lower pin are mainly used to limit the displacement in the x direction and the y direction, thereby completely limiting the relative displacement of the upper and lower shields.

[0013] According to one embodiment of the utility model, a semi-cylinder protrudes downward from the lower end of the upper shield, and the diameter of the semi-cylinder is smaller than the thickness of the upper shield. A concave semi-cylindrical recessed structure is provided at the upper end of the lower shield, and the semi-cylindrical recessed structure corresponds to and complements the semi-cylindrical protruding downward from the upper shield.

[0014] The complementary semi-cylindrical structure can limit the displacement of the upper and lower shields in the y direction and is easy to install. After installation, the connection position of the upper and lower shields feels smoother, and it can also prevent foreign matter from entering the interior of the shield through the gap between the upper and lower shields, thereby protecting internal components.

[0015] According to one embodiment of the utility model, the edge where the upper shield and the lower shield are installed together is provided with a corresponding arc-shaped notch for passing through the combination switch, ignition lock and other equipment. The concave hole column and the circular latch column are both arranged on the inner side of the upper shield and the lower shield, making the outer side of the shield simple and beautiful and the joint smoother.

[0027] The design of the concave hole column 101 and the round latch column 102 can improve the matching relationship of the parts after installation, and the visual smoothness after assembly can enhance the overall visual effect. In addition, the upper and lower shields are optimized from the conventional single z-axis limit to the x-axis limit, which optimizes the assembly effect of the upper and lower shield matching area, reserves more safety margins for the mold, makes it more convenient to fine-tune the margins later, and is faster to install.

[0030] Conventional clamping structures have complex mold structures, large local gaps, uneven surface differences, and it is difficult for the upper and lower shields to match smoothly. This structure can increase the functional strength of the parts by optimizing the clamping design. In addition, the conventional clamping structure has higher requirements on the production process of the injection mold due to its complex design structure, and the product defective rate will also be higher. This structure optimizes the clamping structure, thereby simplifying the structure of the corresponding injection mold, reducing the difficulty of processing the injection mold for the parts, and improving the production efficiency of the product.
