DETAILED DESCRIPTION

[0023] The utility model will be further described below in combination with the drawings:

[0024] The orientation terms involved in the paragraphs of detailed description are only for the convenience of the person skilled in the art to understand the technical solutions recorded in the application according to the visual orientation shown in the drawings. Except for explicit provisions and limitations, the terms'set','mount', 'connect' and the like should be understood broadly, and for the person skilled in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a novel vehicle body side rear door hinge mounting reinforcing structure, which strengthens the vehicle body side mounting structure by optimizing the connecting structure of the upper and lower hinge nut plates 300 of the rear door and the rear door hinge reinforcing plate 100, enhances the vehicle body side hinge mounting strength, improves the reliability and durability of the vehicle, and improves the stability of the rear door.

[0026] As shown in Figures 1 to 7 A novel vehicle body side rear door hinge mounting reinforcing structure, comprising a hinge reinforcing plate 100, an upper hinge nut plate 200, a lower hinge nut plate 300 and a mounting pipe beam assembly 400, the mounting pipe assembly is fixed on one side of the hinge reinforcing plate 100, the upper hinge nut plate 200 is installed at one end of the mounting pipe beam assembly 400 and is fixedly connected with the hinge reinforcing plate 100, the lower hinge nut plate 300 is installed at the other end of the pipe beam assembly and is also fixedly connected with the hinge reinforcing plate 100, wherein the hinge reinforcing plate 100 is provided with a first through hole 101, one side of the mounting pipe beam assembly 400 is provided with a second through hole 411 and the other side is provided with a third through hole 421, and the second through hole 411 and the third through hole 421 are on the same straight line as the first through hole 101.

[0027] It can be understood that the first through hole 101, the second through hole 411 and the third through hole 421 not only reduce the overall weight of the hinge reinforcing plate 100 and the mounting pipe beam assembly 400, but also improve the overall structural strength of the hinge reinforcing plate 100 and the mounting pipe beam assembly 400. On the other hand, it provides wiring space for the cable, and does not need the reinforcing plate and the mounting pipe beam assembly 400 to provide additional wiring space, effectively improving its applicability.

[0028] Optionally, the surface of the hinge reinforcing plate 100 is provided with a plurality of reinforcing through holes 102. In this way, by means of the reinforcing through holes 102, the overall structure of the hinge reinforcing plate 100 can be changed, thereby effectively improving the overall structural strength of the hinge reinforcing plate 100.

[0029] As shown in Figures 4 to 7 The mounting pipe beam assembly 400 includes a pipe beam lower plate 410 and a pipe beam upper plate 420, the pipe beam upper plate 420 is embedded in one side of the pipe beam lower plate 410, and a cavity 430 is defined between the two. In this way, by means of the mounting mode of the two embedded in each other and the cavity 430 defined between the two, the mounting pipe beam assembly 400 provides sufficient structural strength and buffer space when subjected to external force, thereby improving the overall structural strength and impact resistance of the mounting pipe beam assembly 400. In addition, the cavity 430 defined between the two provides a certain wiring space for the cable, so that the mounting pipe beam assembly 400 has functional diversity.

[0030] As shown in Figure 6 The pipe beam lower plate 410 has a first through slot 412 and a second through slot 413 drilled on one side and extending to the other side. In this way, the overall structure of the pipe beam lower plate 410 is changed by means of the first through slot 412 and the second through slot 413, effectively improving the structural strength of the pipe beam lower plate 410. When the pipe beam lower plate 410 is subjected to external force, the external force can be shared, so that the pipe beam lower plate 410 is not easy to deform under the action of external force.

[0031] As shown in Figure 6 The pipe beam upper plate 420 is provided with a beam lower reinforcing plate 440 on the side facing the pipe beam lower plate 410, located above the second through slot 413. In this way, the reinforcing plate installed between the pipe beam upper plate 420 and the pipe beam lower plate 410 not only supports the two, but also makes the cavity 430 between the two more stable when subjected to external force, effectively improving the overall structural strength of the mounting pipe beam assembly 400. In addition, the reinforcing plate arranged between the two also plays a role in force transmission, which can transmit the force to the pipe beam upper plate 420 and / or the pipe beam lower plate 410 when the pipe beam upper plate 420 and / or the pipe beam lower plate 410 is subjected to external force, thereby achieving the effect of dispersion and absorption.

[0032] As shown in Figure 6As shown, the beam lower reinforcing plate 440 comprises a first plate body 441 and a second plate body 442, and both are oppositely arranged. In this way, the first plate body 441 and the second plate body 442 are respectively in abutment with the mouth along position of the second through groove 413, which not only improves the force transmission effect of the periphery of the second through groove 413, but also provides good support to the periphery of the second through groove 413, so that the periphery of the second through groove 413 is not easy to deform under external force.

[0033] Optionally, the upper hinge nut plate 200 is of a closed structure at the end away from the lower hinge nut plate 300, and the end of the installation pipe beam assembly 400 is wrapped inside. In this way, by wrapping the end of the installation pipe beam assembly 400 with the closed structure, when the installation pipe beam assembly 400 is deformed by a larger external force, the installation pipe beam assembly 400 can be limited by its wrapping design, and the displacement of the installation pipe beam assembly 400 with a large distance is reduced.

[0034] As shown in Figure 1 , Figure 2 and Figure 4 , the side of the upper hinge nut plate 200 away from the installation pipe beam assembly 400 is provided with a connecting plate 201. In this way, the installation pipe beam assembly 400 can be fixed to the specified position of the vehicle body by the connecting plate 201.

[0035] Optionally, the end of the lower hinge nut plate 300 away from the upper hinge nut plate 200 is also of a closed structure, and the end of the installation pipe beam assembly 400 is wrapped inside. In this way, the wrapping structure of the upper hinge nut plate 200 has the same effect, and also limits the installation pipe beam assembly 400, so that the installation pipe beam assembly 400 is not easy to displace a large distance when subjected to a large external force.

[0036] Finally, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
