Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to an arc-shaped upper guard plate of an automobile A-pillar. Background Technique

[0002] The upper guard plate of the automobile A-pillar is one of the main decorations inside the automobile. It not only plays a role in beautifying the interior of the automobile, but also plays a key role in the field of vision of the driver during the driving of the automobile.

[0003] The authorized announcement number is CN211076071U, which discloses an arc-shaped upper guard plate of an automobile A-pillar. In the manufacturing process of this patented technology, composite materials are used, which have good flexibility in general environments, and arc-shaped edges are provided at its joints. There are good gaps with other decorative parts and remain in a relatively fixed position with the fixing frame. When the door rotates without a buckle on one side of the door, the upper guard plate of the A-pillar will not become loose; in terms of the overall effect, the cross-sectional area of the upper guard plate of the A-pillar is reduced; however, in this solution, when strengthening the overall guard plate, only composite materials are used for installation. The single clamping method cannot ensure the overall stability of the A-pillar, and its shock absorption, sound insulation and heat insulation capabilities are also weak. Traditional reinforcing ribs generally use I-beams for reinforcement, but the contact surface between the I-beam and the corrugated cross-section is too small to completely conduct the pressure received, resulting in a large gap between the actual strengthening effect and the theoretical strengthening effect, which leads to the easy fracture of the A-pillar. Therefore, an arc-shaped upper guard plate of an automobile A-pillar is needed to improve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: Please refer to Figures 1-4 an arc-shaped upper A-pillar guard plate of an automobile shown in the figure, which includes a main body 1, a rectangular truss assembly 2 is fixedly connected to the side of the main body 1, and a connection assembly 3 is fixedly connected to the side of the rectangular truss assembly 2;

[0027] In this embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the main body 1 includes a housing 101. A inner housing 102 is fixedly connected to the side surface of the housing 101. A sponge rubber pad 107 is fixedly connected to the side surface of the inner housing 102. The rectangular truss assembly 2 includes a connecting rod 201. A horizontal round bar 202 is fixedly connected to the side surface of the connecting rod 201. A vertical round bar 203 is fixedly connected to the top of the connecting rod 201. An inclined round bar 204 is fixedly connected to the side surface of the connecting rod 201. The connecting component 3 includes a supporting plate 301. An expansion joint bolt rod 302 is arranged inside the supporting plate 301. A nut 303 is arranged at the bottom of the expansion joint bolt rod 302. The rectangular truss assembly 2 formed by welding the connecting rod 201, the horizontal round bar 202, the vertical round bar 203 and the inclined round bar 204 has a certain triangular plane space structure, which is easy to meet the requirements of standardized and industrialized production, increases the in-plane mechanical properties of the A-pillar guard plate, improves the out-of-plane stiffness, and can improve the integrity of the overall vehicle structure. Moreover, the equal-ratio structural requirements not only have aesthetics, but also can give full play to the material strength.

[0028] Among them, four connecting rods 201 are provided, and the four connecting rods 201 have the same specifications. A number of horizontal round bars 202, vertical round bars 203 and inclined round bars 204 are provided. A number of supporting plates 301, expansion joint bolt rods 302 and nuts 303 are provided. The expansion joint bolt rod 302 penetrates through the supporting plate 301, and the expansion joint bolt rod 302 is used in cooperation with the nut 303. Fixing the inner housing 102 and the rectangular truss assembly 2 as a whole by using the expansion joint bolt rod 302 and the nut 303 can prevent the weld from cracking caused by impact at the welding place. The sponge rubber pad 107 can be used to buffer and protect the whole A-pillar. The sponge rubber pad 107 is a porous structure material with pores throughout the whole material. It has a small density, excellent elasticity and flexibility, and has high shock absorption, sound insulation and heat insulation properties.

[0029] In this embodiment, referring to Figure 1 and Figure 2 As shown in the figure, a first mounting hole 108 and a second mounting hole 109 are opened on the side surface of the inner housing 102.

A bearing block 106 is fixedly connected to the side surface of the inner housing 102. The microwave emitted by the transmitting antenna of the microwave sensor 103 will be absorbed or reflected when it encounters the object to be measured, causing a change in power. The microwave sensor 103 is mainly composed of a microwave oscillator and a microwave antenna. The microwave oscillator is a device that generates microwaves. The devices that make up the microwave oscillator include klystrons, magnetrons or some solid components. When a collision occurs to the A-pillar, it can give an early warning in time and send a distress signal independently.

The rectangular truss assembly 2 composed of the connecting rod 201, the horizontal round rod 202, the vertical round rod 203, and the inclined round rod 204 has a certain triangular plane space structure, which is easy to meet the requirements of standardized and industrial production, and increases the in-plane mechanical properties of the A-pillar guard plate. Fixing the inner shell 102 and the entire rectangular truss assembly 2 with the expansion joint bolt rod 302 and the nut 303 can prevent the weld from cracking caused by impact at the welded joint, and at the same time, it is also convenient for disassembly. Adding a sponge rubber pad 107 to the guard plate can endow the entire A-pillar with the performance of shock absorption, sound insulation, and heat insulation.
