[0061] It can be understood that the specific arrangement of the first plate segment 121 and the third plate segment 123 can be determined according to actual production requirements and is not specifically limited here.

[0062] Therefore, the first plate segment 121 and the third plate segment 123 avoid the weight reducing hole 112 to prevent the weight reducing hole 112 from affecting the connection between the first plate segment 121 and the third plate segment 123, and the rear end of the first plate segment 121 and / or the rear end of the third plate segment 123 is located on the rear side of the weight reducing hole 112 to increase the area of ​​the hinge reinforcement plate 12, thereby increasing the connection area between the hinge reinforcement plate 12 and the door inner panel 11, and improving the reinforcement effect of the hinge reinforcement plate 12 on the hinge installation area 111, and the hinge reinforcement plate 12 can strengthen the door inner panel 11 near the weight reducing hole 112 to improve the structural strength of the door inner panel 11.

[0065] Among them, a plurality of second mounting holes 1234 are provided to improve the connection effect between the third plate section 123 and the door inner panel 11, and a plurality of hinge connecting holes 125 are provided to improve the connection effect between the hinge and the hinge reinforcement plate 12, thereby facilitating improving the installation stiffness of the hinge.

[0066] Combination Figure 1 and Figure 3 In some embodiments of the utility model, the third plate segment 123 includes a connecting segment 1231 and an extension segment 1232. The connecting segment 1231 is constructed as an L-shaped plate and is connected to the first plate segment 121 and the second plate segment 122, respectively. At the same time, one end of the connecting segment 1231 away from the second plate segment 122 is connected to the extension segment 1232. The extension segment 1232 extends backward from the connecting segment 1231 and the rear end of the extension segment 1232 is located on the rear side of the first weight reduction hole 1121.

The reinforcing portion 1233 can increase the connection strength between the connecting section 1231 and the extending section 1232, thereby increasing the strength of the third plate section 123, and increasing the reinforcing effect of the hinge reinforcing plate 12 on the hinge mounting area 111.

[0068] Among them, four hinge connection holes 125 can be arranged on the connecting section 1231, and the four hinge connection holes 125 are arranged at intervals on the connecting section 1231. A hinge connection hole 125 can be arranged at a position opposite to the hinge installation area 111 of the extension section 1232. By arranging multiple hinge connection holes 125 at intervals on the third plate section 123, the installation points of the hinges can be evenly distributed, thereby improving the stability of the hinge installation.

[0069] Combination Figure 1 and Figure 3 In some embodiments of the present invention, the hinge reinforcement plate 12 is provided with a reinforcement rib 124 on the surface of the side facing away from the door inner panel 11. There are multiple reinforcement ribs 124, and the arrangement of the multiple reinforcement ribs 124 at different positions can be different.

[0070] Specifically, the reinforcing rib 124 is arranged on the side of the hinge reinforcement plate 12 away from the door inner panel 11 and bulges from the plate surface of the hinge reinforcement plate 12 in the direction away from the door inner panel 11, which ensures the reinforcing effect of the reinforcing rib 124 on the hinge reinforcement plate 12 while preventing the reinforcing rib 124 from interfering with the installation of the hinge reinforcement plate 12, making it easier for the hinge reinforcement plate 12 to fit closely with the door inner panel 11, thereby facilitating the reinforcement effect of the hinge reinforcement plate 12 on the hinge installation area 111.

[0071] Optionally, at the location of the hole structure on the hinge reinforcement plate 12 (such as the first mounting hole 1212, the hinge connection hole 125, the second mounting hole 1234 and other structures), a plurality of reinforcing ribs 124 can be arranged around the hole structure to reinforce the hole structure in the circumferential direction of the hole structure to prevent failure.

[0072] One or more reinforcing ribs 124 are arranged in sequence in the extension direction of the hinge reinforcement plate 12, and one end of each two adjacent reinforcing ribs 124 are connected and the other end is spaced apart, so as to improve the reinforcing effect of the reinforcing ribs 124 on the hinge reinforcement plate 12 and improve the structural strength of the hinge reinforcement plate 12.

[0073] In some embodiments of the utility model, the hinge reinforcement plate 12 is a cast aluminum part, so that the weight of the hinge reinforcement plate 12 can be reduced while ensuring the strength and rigidity of the hinge reinforcement plate 12, which is conducive to realizing the lightweight design of the trackless sliding door, and can ensure the corrosion resistance of the hinge reinforcement plate 12 and improve the service life of the hinge reinforcement plate 12.

[0074] In some embodiments of the present invention, the thickness dimension of the hinge reinforcement plate 12 is L1, and L1 satisfies the relationship 1.5mm<L1<3.5mm. Preferably, the thickness dimension of the hinge reinforcement plate 12 can be 2mm, and the protrusion dimension of the reinforcement rib 124 relative to the hinge reinforcement plate 12 is L2, and satisfies the relationship 2mm<L2<4mm. Preferably, L2 can be 3mm, so as to ensure the reinforcement effect of the hinge reinforcement plate 12 on the hinge installation area 111 while reducing the weight of the hinge reinforcement plate 12, thereby avoiding a significant increase in the weight of the hinge reinforcement plate 12 due to increasing the area of ​​the hinge reinforcement plate 12.

[0075] In addition, in order to ensure the structural strength of the hole structure on the hinge reinforcement plate 12, the hinge reinforcement plate 12 at the outer peripheral edge of the hole structure can be partially thickened to prevent the hole structure from failing.

[0076] In the related art, the hinge reinforcement plate is constructed as a steel plate, and the thickness of the hinge reinforcement plate is 3 mm. However, it is only arranged opposite to the hinge installation area and close to the weight reduction hole, resulting in poor reinforcement effect of the hinge reinforcement plate on the hinge installation area. In addition, the density of the steel plate is high, resulting in a large weight of the hinge reinforcement plate.

[0077] The present application increases the area of ​​the hinge reinforcement plate 12 and constructs the hinge reinforcement plate 12 as a cast aluminum part to improve the reinforcement effect of the hinge reinforcement plate 12 on the hinge installation area 111 and reduce the weight of the hinge reinforcement plate 12, which is conducive to realizing a lightweight design of the trackless sliding door.

[0078] The vehicle according to the utility model comprises the above-mentioned trackless sliding door.

[0079] Since the vehicle is provided with the above-mentioned trackless sliding door, the area of ​​the hinge reinforcement plate 12 is increased and the hinge reinforcement plate 12 is connected to the window reinforcement plate 13 and the door lock reinforcement plate 14 at the same time to improve the reinforcement effect of the hinge reinforcement plate 12 on the hinge installation area 111, thereby improving the rigidity of the hinge installation area 111 and reducing the risk of deformation of the hinge installation area 111.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
