[0002] The comfort of car seats is one of the important indicators to measure the quality of a car, especially for long-distance driving. The design of the seat directly affects the driver's fatigue level and riding experience. In modern car seat design, leg rests are an important component to improve comfort, and their structural design is increasingly valued. The design of leg rests must not only take into account ergonomics, but also structural strength and stability to ensure reliability and durability under long-term use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0024] like Figure 1-5As shown, the utility model provides a technical solution: a rear support plate structure of a leg rest of a car seat, comprising a mounting plate 1, the mounting plate 1 comprising an arcuate section 101 and a straight section 102, a stabilizing frame 2 being fixedly connected to the surface of the arcuate section 101, and an end of the stabilizing frame 2 extending to the straight section 102 and fixedly connected to the straight section 102, a group of symmetrical mounting members 3 being fixedly connected to the surface of the straight section 102, a reinforcing rib 301 being fixedly connected to the outer sides of the mounting members 3, and the reinforcing rib 301 being fixedly connected to the surface of the straight section 102, a group of symmetrical supporting members 4 being fixedly connected to the surface of the arcuate section 101, a reinforcing strip 5 being fixedly connected to the top of the supporting members 4, a plurality of fixing members 6 being fixedly connected to the surface of the arcuate section 101, and the fixing members 6 being distributed along the length direction of the mounting plate 1, a spacer 7 being fixedly connected to the top of the fixing member 6, and a plurality of positioning grooves 8 being formed on the arcuate section 101 along its length direction.

[0025] The mounting plate 1 is configured as an arc segment 101 and a straight segment 102, and is integrally formed, which can better fit the curve of the leg, and the lower plate surface provides a more advantageous space for the structural setting; the fixing members 6 are divided into two categories, the first type of fixing members 6 are symmetrically arranged at both ends of the arc segment 101, and the second type of fixing members 6 are located in the middle position of the arc segment 101, and the spacers 7 have different shapes according to different types of fixing members 6. The first type of spacers 7 are provided with three limiting holes, and the second type of spacers 7 are provided with two limiting holes. These limiting holes are used together for docking other components.

[0026] like Figure 1 and Figure 3 As shown, the stabilizing frame 2 includes a stabilizing bar 201, a connecting bar 202 and a splicing bar 203. The stabilizing bar 201 is distributed in a linear array along the length direction of the mounting plate 1. The splicing bars 203 are arranged in pairs. The splicing bars 203 pass through the stabilizing bar 201 and are fixedly connected to the stabilizing bar 201. The connecting bars 202 are distributed in an staggered linear array and are fixedly connected between adjacent stabilizing bars 201.

[0027] The stabilizing strips 201 are linearly distributed on the arc segment 101 . Since the arc segment 101 has more notches, the structural strength of the arc segment 101 is increased, so that the stress is dispersed onto the stabilizing strips 201 .

[0028] like Figure 1 As shown, the stabilizing bar 201 is fixedly connected to the arc segment 101 , part of the stabilizing bar 201 is fixedly connected to the straight segment 102 , the end of the stabilizing bar 201 close to the straight segment 102 is a triangular structure, and the splicing bar 203 and the connecting bar 202 are both fixedly connected to the arc segment 101 .

[0029] The triangular structure helps to improve the structural strength of the stabilizing frame 2 .

[0030] like Figure 1 and Figure 4 As shown, a mounting hole 302 is provided at the top of the mounting member 3 , the bottom of the mounting member 3 is hollowed out, and the end of a portion of the stabilizing strip 201 is fixedly connected to the outer side of the mounting member 3 .

[0031] The mounting members 3 are arranged in pairs and are used for installing and fixing other components. Bolts are inserted and tightened through the mounting holes 302. The mounting members 3 are hollowed out to facilitate tool operation, and the reinforcing rib 301 is used to increase the contact area between the mounting members 3 and the mounting plate 1, thereby improving the overall firmness of the mounting members 3, thereby improving the stability of other components installed on the mounting plate 1.

[0032] like Figure 1 As shown, a positioning hole 103 and a positioning hole 2 104 are provided on the surface of the straight section 102 . The positioning hole 103 is circular and located on one side of the mounting member 3 . The positioning hole 2 104 is strip-shaped and located on one side of the other mounting member 3 .

[0033] After other components are fixed to the mounting plate 1 through the mounting member 3, the positions of the mounting components are corrected through the positioning holes 103 and 104 of different shapes to avoid displacement, thereby further improving the accuracy of the installation.

[0034] like Figure 1 and Figure 5 As shown, the reinforcing strip 5 includes a second reinforcing rib 501 and a third reinforcing rib 502. There are three second reinforcing ribs 501, and the second reinforcing ribs 501 are evenly fixedly connected to the top of the support member 4. The third reinforcing rib 502 passes through the second reinforcing rib 501, and the third reinforcing rib 502 is fixedly connected to the second reinforcing rib 501.

[0035] After other components are installed, they are supported by the support member 4. Since the support members 4 are respectively arranged at both ends of the mounting plate 1, they can play a supporting role to the greatest extent, reduce the extrusion of the mounting plate 1 and other components, and further improve the structural strength of the support member 4 by staggered arrangement of the second reinforcing rib 501 and the third reinforcing rib 502.

[0036] like Figure 1 As shown, the fixing member 6 , the positioning groove 8 and the supporting member 4 are fixedly connected to different positions of the stabilizing bar 201 , the straight section 102 is fixedly connected to a plurality of partition blocks 9 , and the partition blocks 9 are unevenly distributed along the length direction of the mounting plate 1 .

[0037] The partition block 9 helps to correct the positions of other components and can limit the outward movement of other components.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
