[0025] The body side reinforcement plate rear assembly in the application can be applied to related structures of vehicles, rail transit or industrial equipment, etc. The application will be described by taking the application of the body side reinforcement plate rear assembly to vehicles as an example.

[0026] Please refer to Figures 1 to 3 , Figure 1 is a schematic diagram of the overall structure of an embodiment of the body side reinforcement plate rear assembly of the application; Figure 2 is a schematic diagram of the side reinforcement plate rear sub-assembly of an embodiment of the body side reinforcement plate rear assembly of the application; Figure 3 is a schematic diagram of the side reinforcement plate lower sub-assembly of an embodiment of the body side reinforcement plate rear assembly of the application.

[0027] In one aspect of the application, a body side reinforcement plate rear assembly 10 is provided. The body side reinforcement plate rear assembly 10 comprises a first sub-assembly 11 and a second sub-assembly 12; the first sub-assembly 11 is provided with a first body mounting hole 1131; the second sub-assembly 12 is connected to the first sub-assembly 11 and is provided with a second body mounting hole 1141; the position degree of the first body mounting hole 1131 is the same as that of the second body mounting hole 1141.

[0028] From the above structure, first, in the application, the first sub-assembly 11 and the second sub-assembly 12 are connected, so that the body side reinforcement plate rear assembly 10 can be split into at least two parts for connection. Compared with the existing technology of manufacturing the body side reinforcement plate rear assembly 10 as a whole, the application can effectively reduce the difficulty of mold manufacturing and stamping process, and better improve the part precision and quality of the first sub-assembly 11 and the second sub-assembly 12.

[0029] Secondly, the first body mounting hole 1131 is provided in the first sub-assembly 11, and the second body mounting hole 1141 is provided in the second sub-assembly 12. The position degree of the first body mounting hole 1131 and the second body mounting hole 1141 can be controlled separately, so that the position degree of the first body mounting hole 1131 and the second body mounting hole 1141 is the same, thereby further improving the installation precision of the first body mounting hole 1131 and the second body mounting hole 1141, and effectively reducing the size chain of the body side reinforcement plate rear assembly 10. The position degree of the first body mounting hole 1131 and the second body mounting hole 1141 is set to be the same, which not only makes the installation precision of the first body mounting hole 1131 and the second body mounting hole 1141 consistent when the body side reinforcement plate rear assembly 10 is installed on the vehicle body, but also facilitates the use of the same detection standard for inspection in the production process, thereby improving the production efficiency and the quality stability of the product.

[0030] It should be noted that the position tolerance of the mounting hole refers to the allowable variation of the actual position of the mounting hole relative to the ideal position of the design. Therefore, the smaller the position tolerance of the mounting hole, the smaller the allowable variation between the actual position and the ideal position of the mounting hole, and the higher the installation accuracy of the mounting hole.

[0031] The first sub-assembly 11 and the second sub-assembly 12 can also be connected by welding, fastener connection, etc., which is not limited here.

[0032] In some embodiments of the present application, the first sub-assembly 11 includes a rear section sub-assembly 110 of a side wall reinforcement panel, which forms a first mounting surface 113, and the first mounting surface 113 is provided with a first vehicle body mounting hole 1131; the second sub-assembly 12 includes a lower section assembly 120 of a side wall reinforcement panel, which forms a second mounting surface 114, and the second mounting surface 114 is provided with a second vehicle body mounting hole 1141. In the present application, the rear section sub-assembly 110 of the side wall reinforcement panel is connected with the vehicle body through the first vehicle body mounting hole 1131, and the lower section assembly 120 of the side wall reinforcement panel is connected with the vehicle body through the second vehicle body mounting hole 1141, thereby realizing the connection between the rear section assembly 10 of the side wall reinforcement panel of the vehicle body and the vehicle body. Moreover, since the position tolerance of the first vehicle body mounting hole 1131 and the second vehicle body mounting hole 1141 is the same, the installation accuracy of the first vehicle body mounting hole 1131 and the second vehicle body mounting hole 1141 can be further improved, thereby effectively reducing the dimension chain of the rear section assembly 10 of the side wall reinforcement panel of the vehicle body. In addition, the first mounting surface 113 and the second mounting surface 114 can increase the contact area between the rear section sub-assembly 110 of the side wall reinforcement panel and the lower section assembly 120 of the side wall reinforcement panel and the vehicle body, thereby improving the stability of the connection between the two and the vehicle body, and improving the stability of the connection between the rear section assembly 10 of the side wall reinforcement panel of the vehicle body and the vehicle body, so as to improve the reliability of the vehicle.

[0033] In some embodiments of the present application, the rear section sub-assembly 110 of the side wall reinforcement panel includes an upper section assembly 111 of a side wall reinforcement panel and a rear quarter wheelhouse outer panel sub-assembly 112. The first vehicle body mounting hole 1131 is arranged on the rear quarter wheelhouse outer panel sub-assembly 112. The upper section assembly 111 of the side wall reinforcement panel and the rear quarter wheelhouse outer panel sub-assembly 112 are connected. In the present application, by arranging the rear section sub-assembly 110 of the side wall reinforcement panel as the upper section assembly 111 of the side wall reinforcement panel and the rear quarter wheelhouse outer panel sub-assembly 112, the rear section sub-assembly 110 of the side wall reinforcement panel can be divided into two parts for connection, which can effectively reduce the difficulty of mold manufacturing and stamping process compared with the whole stamping mode of the rear section sub-assembly 110 of the side wall reinforcement panel in the prior art, and can better improve the part precision and quality of the upper section assembly 111 of the side wall reinforcement panel and the rear quarter wheelhouse outer panel sub-assembly 112.

[0034] In the process of assembling the body side wall reinforcement plate rear assembly 10, the side wall reinforcement plate upper assembly 111 and the rear side wall wheel cover outer plate sub-assembly 112 are connected first to form a side wall reinforcement plate rear sub-assembly 110, and then the side wall reinforcement plate rear sub-assembly 110 and the side wall reinforcement plate lower assembly 120 are connected to form the body side wall reinforcement plate rear assembly 10.

[0035] The connection between the side wall reinforcement plate upper assembly 111 and the rear side wall wheel cover outer plate sub-assembly 112 can be by welding, fastener connection, etc., which is not limited here.

[0036] In some embodiments of the present application, the position tolerance of the first body mounting hole 1131 and the second body mounting hole 1141 is 2-4mm. In the present application, the position tolerance of the first body mounting hole 1131 and the second body mounting hole 1141 is set to be between 2-4mm. On the one hand, this can effectively reduce the cumulative assembly error between multiple components, improve the installation precision of the body side wall reinforcement plate rear assembly 10, and thus effectively reduce the dimension chain of the body side wall reinforcement plate rear assembly 10. On the other hand, setting the position tolerance of the mounting hole to be between 2-4mm not only has certain requirements for the position accuracy of the mounting hole, but also does not require too high, so that this kind of processing technology is relatively easy to realize, thereby improving the position accuracy while improving the production efficiency.

[0037] When the position tolerance of the first body mounting hole 1131 and the second body mounting hole 1141 is less than 2mm, the machining precision will be improved, affecting the overall production efficiency. When the position tolerance of the first body mounting hole 1131 and the second body mounting hole 1141 is greater than 4mm, the position tolerance is too high, which will increase the error between the assembled components, thereby reducing the installation precision of the body side wall reinforcement plate rear assembly 10. Therefore, when the position tolerance of the first body mounting hole 1131 and the second body mounting hole 1141 is between 2-4mm, not only can the assembly error between each component be reduced to improve the installation precision of the body side wall reinforcement plate rear assembly 10, but also the overall production efficiency can be improved.

[0038] The position tolerance of the first body mounting hole 1131 and the second body mounting hole 1141 can be 2mm, 2.3mm, 2.4mm, 2.6mm, 2.8mm, 3.2mm, 3.6mm, 3.7mm, 3.9mm, 4mm, etc., which will not be repeated here. Only the position of the first body mounting hole 1131 and the position tolerance of the second body mounting hole 1141 need to be the same.

[0039] Please refer to Figure 1 , Figure 2 Please refer to Figure 4 , Figure 4is a structural schematic view of a rear side wall wheel cover outer plate sub-assembly of an embodiment of the rear side wall reinforcement plate assembly of the application. In some embodiments of the application, a first welding surface 115 is formed on the rear side wall wheel cover outer plate sub-assembly 112, and a second welding surface 121 is formed on the lower side wall reinforcement plate assembly 120. The first welding surface 115 and the second welding surface 121 are welded to connect the rear side wall reinforcement plate sub-assembly 110 and the lower side wall reinforcement plate assembly 120. In the present application, the welding area between the rear side wall reinforcement plate sub-assembly 110 and the lower side wall reinforcement plate assembly 120 can be effectively increased by the first welding surface 115 and the second welding surface 121, thereby improving the connection strength and stability of the rear side wall reinforcement plate sub-assembly 110 and the lower side wall reinforcement plate assembly 120.

[0040] In some embodiments of the application, the first welding surface 115 and the second welding surface 121 are both flat surfaces. In the present application, the first welding surface 115 and the second welding surface 121 are flat surfaces. On the one hand, this can improve the fit between the first welding surface 115 and the second welding surface 121, thereby reducing the risk of virtual welding or ineffective welding when the rear side wall reinforcement plate sub-assembly 110 and the lower side wall reinforcement plate assembly 120 are welded, and thereby improving the connection strength and stability between the rear side wall reinforcement plate sub-assembly 110 and the lower side wall reinforcement plate assembly 120. On the other hand, the above arrangement can also facilitate the alignment and fixation of the rear side wall reinforcement plate sub-assembly 110 and the lower side wall reinforcement plate assembly 120 and the rear side wall reinforcement plate assembly 10 of the vehicle body with the components to be welded during welding with the remaining structure, thereby reducing the adjustment time and workload during assembly, and thereby improving the efficiency of welding.

[0041] Please refer to Figure 1 , Figure 2 , Figure 4 Please refer to Figure 5 , Figure 5 is Figure 1 is a cross-sectional structural schematic view of A-A in the above-mentioned embodiment. In some embodiments of the application, the angle A between the planes of the first welding surface 115 and the second welding surface 121 and the planes of the length and width directions of the vehicle is 10°-15° in the width direction of the vehicle. The above arrangement can ensure that the rear side wall reinforcement plate assembly 10 of the vehicle body can fit with the welding surfaces of the structures to be assembled when it is assembled on different vehicles, thereby effectively improving the applicability of the rear side wall reinforcement plate assembly 10 of the vehicle body. When the angle A between the planes of the first welding surface 115 and the second welding surface 121 and the planes of the length and width directions of the vehicle is less than 10° or greater than 15°, it can affect the fit between the above-mentioned welding surfaces and the welding surfaces of the structures to be assembled, thereby affecting the welding precision therebetween.

[0042] The angle A between the plane where the first welding surface 115 and the second welding surface 121 are located and the plane where the vehicle width direction is located can be 10°, 11°, 11.5°, 12°, 12.2°, 12.8°, 13°, 13.6°, 14.2°, 14.8°, 15°, and the like, which will not be repeated here.

[0043] In some embodiments of the present application, the width L of the first welding surface 115 and the second welding surface 121 in the vehicle width direction is greater than or equal to 20 mm. When the width L of the first welding surface 115 and the second welding surface 121 in the vehicle width direction is less than 20 mm, the area of the welding is small, which not only easily causes virtual welding or ineffective welding, but also is not conducive to the operation process of the production personnel. Therefore, the above setting can effectively increase the contact area between the first welding surface 115 and the second welding surface 121, thereby reducing the occurrence of virtual welding or ineffective welding when the side wall reinforcement plate rear section sub-assembly 110 and the side wall reinforcement plate lower section assembly 120 are welded, and further improving the connection strength and connection stability between the side wall reinforcement plate rear section sub-assembly 110 and the side wall reinforcement plate lower section assembly 120. On the other hand, due to the increase of the contact area, it can also provide more space for the production personnel in the welding operation process, which not only improves the operation efficiency of the production personnel, but also improves the success rate of welding.

[0044] In some embodiments of the present application, the width L of the first welding surface 115 and the second welding surface 121 in the vehicle width direction can be 20 mm, 22 mm, 23 mm, 24.2 mm, 26 mm, 26.5 mm, 26.8 mm, 27 mm, 27.6 mm, 28.3 mm, 29 mm, 29.5 mm, 29.7 mm, 29.9 mm, 30 mm, and the like, which will not be repeated here.

[0045] In some embodiments of the present application, the first mounting surface 113 is a back door hinge mounting surface, the first vehicle body mounting hole 1131 is a back door hinge mounting hole, the second mounting surface 114 is a rear door lock catch mounting surface, and the second vehicle body mounting hole 1141 is a rear door lock catch mounting hole. Through the above manner, the installation position of the rear back door and the rear door lock catch can be more accurate, thereby making the door opening and closing smooth and the locking firm, and further improving the reliability and durability of the vehicle. In addition, the position degree of the back door hinge mounting hole and the rear door lock catch mounting hole is the same, which can also improve the installation precision and facilitate the consistency of detection requirements in the production process, thereby improving the production efficiency and the stability of product quality.

[0046] In a second aspect of the present application, a vehicle is provided, which comprises a vehicle body and the rear quarter panel assembly 10 of any one of the above. The rear quarter panel assembly 10 is arranged at the rear side of the vehicle body. Specifically, since the vehicle comprises the rear quarter panel assembly 10 of the above embodiments, the vehicle also has the advantages of the rear quarter panel assembly 10 of the above, which will not be repeated here. In addition, the vehicle can also have the advantages of smooth opening and closing of the door, and firm locking, which can improve the reliability and durability of the vehicle, and also effectively enhance the structural strength of the region, improve the quality of the vehicle, and further improve the experience of the driver.
