Description

Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to an automotive seat cover structure that can provide high torque for installation in both forward and reverse positions. Background Technology

[0002] Existing automotive seat cover screw structures are achieved through conventional injection molding processes, which involve pre-drilling screw mounting holes in the cover. This type of structure suffers from poor stability, low strength, and the torque required for screw installation is limited to 2N-5N. Furthermore, the cover is prone to cracking during installation. In addition, due to the limitations of the draft angle of the injection mold, existing cover panels can only be fitted with screws in one direction (perpendicular to the draft angle), which restricts the installation of cover panel connectors. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, this utility model provides a car seat guard plate structure that can provide high torque for installation in both forward and reverse directions. The guard plate structure has a torque-increasing component with a specific structure embedded at the screw installation position. The setting of the torque-increasing component with a specific structure can enable the screw torque to reach 10N-15N, thereby improving the stability and strength of the connection structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A car seat protector structure that provides high torque for installation in both forward and reverse positions includes a protector body. The protector body has an I-shaped torque amplifying component embedded in the mounting screw positions via an injection molding process. The upper and lower ends of the I-shaped torque amplifying component are polygonal, the middle part is cylindrical, and a through-hole is provided at the axis. The bottom surface of the lower end of the I-shaped torque amplifying component is on the same horizontal line as the bottom surface of the protector body. The upper end of the I-shaped torque amplifying component is entirely embedded in the protector body. A clearance hole is provided at the position opposite to the internal threaded hole of the I-shaped torque amplifying component in the protector body.

[0006] As a preferred embodiment of the utility model, the upper end of the I-shaped torque-increasing component is a hexagonal structure, and the lower end is a hexagonal structure.

[0007] As a preferred embodiment of the utility model, the guard plate connector is installed on the front or back of the guard plate body. When the guard plate connector is installed on the front of the guard plate body, the screw is driven in from the front of the guard plate body and threadedly connected to the I-shaped torque-increasing component. When the guard plate connector is installed on the back of the guard plate body, the screw is driven in from the back of the guard plate body and threadedly connected to the I-shaped torque-increasing component.

[0008] Advantages and beneficial effects of this utility model:

[0009] (1) The automotive seat guard structure provided by this utility model has a torque-increasing component with a specific injection-molded structure (I-shaped) embedded at the screw installation position. The setting of the torque-increasing component with a specific structure can make the screw torque reach 10N-15N, which improves the stability and strength of the connection structure.

[0010] (2) The upper and lower ends of the I-shaped torque-increasing component of this utility model are both polygonal structures. The design of the multi-deformable I-shaped structure can form an "interlocking" structure between the torque-increasing component and the protective plate body, making the fixation more secure and avoiding the phenomenon of the torque-increasing component rotating when screwing.

[0011] (3) The protective plate structure provided by this utility model can completely solve the problem that the protective plate is easily cracked, and the screws can be installed from both the front and back directions, which makes the installation of the protective plate connector more convenient and flexible.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. 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.

[0016] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0017] like Figures 1 to 3As shown, this embodiment provides a car seat protector structure that can provide high torque for installation in both forward and reverse positions. It includes a protector body 1. The protector body 1 has an I-shaped torque amplifying component 2 pre-embedded at the mounting screw 4 locations using an injection molding process. The upper end 201 of the I-shaped torque amplifying component 2 has a polygonal structure, the lower end 203 has a polygonal structure, and the middle part 202 has a cylindrical structure. A through-hole (unmarked) is provided at the axis. The bottom surface of the lower end 203 of the I-shaped torque amplifying component is on the same horizontal line as the bottom surface of the protector body 1. The upper end 201 of the I-shaped torque amplifying component is entirely pre-embedded within the protector body 1. A clearance hole (unmarked) is provided at the position opposite to the internal thread hole of the I-shaped torque-increasing component 1; the guard plate connector 3 can be installed on the front or the back of the guard plate body 1. When the guard plate connector 3 is installed on the front of the guard plate body 1, the screw 4 is driven in from the front of the guard plate body 1 and threadedly connected to the I-shaped torque-increasing component 2, so as to achieve a stable connection between the guard plate body 1 and the guard plate connector 3; when the guard plate connector 3 is installed on the back of the guard plate body 1, the screw 4 is driven in from the back of the guard plate body 1 and threadedly connected to the I-shaped torque-increasing component 2, so as to achieve a stable connection between the guard plate body 1 and the guard plate connector 3.

[0018] Furthermore, such as Figure 3 As shown in this embodiment, the upper end 201 of the I-shaped torque-increasing component has a hexagonal structure, and the lower end 203 has a hexagonal structure.

[0019] In this embodiment, by pre-embedding a polygonal I-shaped torque-increasing component at the connection of the protective plate body 1, the screw torque can reach 10N-15N, which is greater than that of pre-embedding cylindrical or ordinary hexagonal torque-increasing components.

[0020] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
