Description

Technical Field

[0001] This utility model belongs to the field of vehicle manufacturing technology, and in particular relates to a door hinge installation structure. Background Technology

[0002] Door hinges are used to install car doors onto the vehicle and are an important component supporting the door. Existing door hinges are connected to the A-pillar or B-pillar of the vehicle body through a hinge mounting plate. The door hinge mounting plate structure is located inside the cavity of the A-pillar or B-pillar of the vehicle body. Its main function is to provide mounting and fixing points for the door hinges, and at the same time, through its own structure, it provides sufficient rigidity and strength for the door, and works with surrounding parts to increase the vehicle body performance.

[0003] However, the hinge mounting plate structure needs to be welded to surrounding parts to achieve a reinforcing effect. The welded overlap and reinforcing features result in larger and heavier parts, which does not meet the requirements of automotive lightweighting development.

[0004] In addition, existing hinge mounting plates have poor platform compatibility, and can only be designed to adapt to different vehicle models, lacking broad applicability. Utility Model Content

[0005] In view of the defects or deficiencies in the existing technology, this utility model provides a door hinge mounting structure that can reduce the weight of the hinge mounting plate and improve the applicability of the hinge mounting plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a door hinge mounting structure, including a side panel, an A-pillar under-reinforcement plate, and a hinge mounting plate. The side panel, the A-pillar under-reinforcement plate, and the hinge mounting plate are arranged in sequence, and the hinge mounting plate is fixed on the inner side of the A-pillar under-reinforcement plate. The hinge mounting plate has notches at both ends and an opening in the middle. The inner side of the A-pillar reinforcement plate is provided with an upper flap, a lower flap, and a middle flap. The upper flap and the lower flap are respectively provided with the notches at both ends of the hinge mounting plate, and the middle flap is provided with the opening in the middle of the hinge mounting plate.

[0007] Furthermore, the hinge mounting plate includes a mounting plate body, and a nut mounting seat is fixed on the upper surface of the mounting plate body. There are two nut mounting seats, which are arranged side by side along the length of the mounting plate body, and the nut mounting seats are integrally formed with the mounting plate body.

[0008] Furthermore, the nut mounting base includes a connecting section and a fixing section. The fixing section is located above the connecting section and is connected to the mounting plate body through the connecting section. A nut is fixed to the top of the fixing section.

[0009] Furthermore, a bolt mounting hole is provided at the axis of the top surface of the nut mounting base, and the bolt mounting hole penetrates the nut mounting base and the mounting plate body.

[0010] Furthermore, a serrated structure is provided on the bottom surface of the mounting plate body.

[0011] Furthermore, both the upper and lower flaps are perpendicular to the lower reinforcement plate of the A-pillar. Both the upper and lower flaps are located in the notches at both ends of the mounting plate body, and the upper and lower flaps are spaced at a set distance from the inner walls of the notches at both ends of the mounting plate body.

[0012] Furthermore, the middle flap is L-shaped and includes a fixing plate and a connecting plate. The fixing plate is connected to the lower reinforcing plate of the A-pillar through the connecting plate.

[0013] Furthermore, the fixing plate is arranged parallel to the A-pillar under the reinforcing plate, the connecting plate is arranged perpendicular to the fixing plate, and the length of the connecting plate is the same as the thickness of the mounting plate body.

[0014] Furthermore, the mounting plate body is located between the fixed plate and the A-pillar under the reinforcing plate, and the bottom surface of the fixed plate is in contact with the top surface of the mounting plate body, and the two sides of the connecting plate are spaced at a set distance from the inner wall of the opening.

[0015] Furthermore, through holes are provided on both the outer side panel and the lower reinforcement plate of the A-pillar, and the through holes are corresponding to the bolt mounting holes on the hinge mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features notches and openings on the mounting plate body, and upper, lower, and middle flaps on the A-pillar reinforcement plate. The upper and lower flaps correspond to the notches at both ends of the mounting plate body, limiting the two ends of the hinge mounting plate. The middle flap corresponds to the opening in the middle of the mounting plate body, fixing the hinge mounting plate. This connection structure eliminates the need for welding the hinge mounting plate to surrounding components, thus eliminating the need for welding overlap edges and reinforcing features, reducing the weight of the hinge mounting plate. Furthermore, the hinge mounting plate can be fixed simply by placing the upper, lower, and middle flaps at the corresponding positions on the A-pillar or B-pillar of the vehicle, without requiring adaptation design for different vehicle models, thus improving the applicability of the hinge mounting plate.

[0017] 2. This utility model, by setting a serrated structure on the bottom surface of the mounting plate body, can increase the friction between the hinge mounting plate and the A-pillar reinforcement plate when the hinge mounting bolts are tightened, thereby preventing the car door from sliding down under gravity after the hinge is installed.

[0018] 3. This utility model provides the necessary allowance for door installation and adjustment by providing gaps between the upper and lower flaps and the inner wall of the notch, as well as between the two sides of the connecting plate and the inner wall of the opening.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A typical embodiment of this utility model is as follows: Figure 1 As shown, a door hinge mounting structure includes a side panel 1, an A-pillar under-reinforcement plate 2, and a hinge mounting plate 3. The side panel 1, the A-pillar under-reinforcement plate 2, and the hinge mounting plate 3 are arranged sequentially. The side panel 1 is located on the outermost side and is welded and fixed to the outer surface of the A-pillar under-reinforcement plate 2, serving as the mating surface for hinge mounting. The A-pillar under-reinforcement plate 2 is located between the side panel 1 and the hinge mounting plate 3, serving as a reinforcement structure for the A-pillar cavity. The hinge mounting plate 3 is snapped onto the inner side of the A-pillar under-reinforcement plate 2 to fix the hinge.

[0022] Among them, such as Figure 2As shown, the hinge mounting plate 3 includes a mounting plate body 31. A nut mounting seat 32 is fixed on the upper surface of the mounting plate body 31. There are two nut mounting seats 32, which are arranged side by side along the length of the mounting plate body 31. The nut mounting seats 32 are integrally formed with the mounting plate body 31. The nut mounting seat 32 includes a connecting section 320 and a fixing section 321. The fixing section 321 is located above the connecting section 320 and is connected to the mounting plate body 31 through the connecting section 320. The connecting section 320 is annular, with its bottom surface connected to the mounting plate body 31 and its top surface connected to the bottom surface of the fixing section 321. The fixing section 321 is frustum-shaped, and the axes of the fixing section 321 and the connecting section 320 coincide. The diameter of the bottom surface of the fixing section 321 is smaller than the diameter of the connecting section 320. The top of the fixing section 321 is used to fix the nut.

[0023] The nut mounting base 32 is provided to facilitate the fixing of the nut and ensure the stability of the connection between the nut and the hinge mounting plate 3.

[0024] A bolt mounting hole 33 is provided at the axis of the top surface of the nut mounting base 3. The bolt mounting hole 33 passes through the nut mounting base 32 and the mounting plate body 31. The hinge mounting bolt can pass through the bolt mounting hole 33 from one side of the bottom surface of the mounting plate body 31 and be threadedly connected to the nut at the top of the nut mounting base 32, thereby fixing the hinge.

[0025] The mounting plate body 31 has a serrated structure on its bottom surface. During installation, the bottom surface of the mounting plate body 31 contacts the inner surface of the A-pillar lower reinforcing plate 2. By setting the serrated structure on the bottom surface of the mounting plate body 31, the friction between the hinge mounting plate 3 and the A-pillar lower reinforcing plate 2 can be increased when the hinge mounting bolts are tightened, thereby preventing the door from sliding down under gravity after the hinge is installed.

[0026] Both ends of the mounting plate body 31 are provided with notches 34, the cross-section of the notches 34 is U-shaped, and the middle of the upper surface of the mounting plate body 31 is provided with an opening 35, the cross-section of the opening 35 is rectangular.

[0027] like Figure 3 As shown, an upper flap 21, a lower flap 22 and a middle flap 23 are provided on the inner surface of the A-pillar under reinforcement plate 2. The upper flap 21 and the lower flap 22 are respectively provided with the notches 34 at both ends of the mounting plate body 31, and the middle flap 23 is provided with the opening 35 in the middle of the mounting plate body 31.

[0028] The upper flap 21, lower flap 22 and middle flap 23 are all formed by laser cutting and bending of the A-pillar lower reinforcing plate 2. The upper flap 21 and lower flap 22 are both set perpendicular to the A-pillar lower reinforcing plate 2. After installation, the upper flap 21 and lower flap 22 are located in the notches 34 at both ends of the mounting plate body 31, thereby using the upper flap 21 and lower flap 22 to limit the two ends of the hinge mounting plate 3.

[0029] Furthermore, such as Figure 4 As shown, the upper flap 21 and the lower flap 22 are respectively spaced at a set distance from the inner walls of the notches 34 at both ends of the mounting plate body 31. In this embodiment, the upper flap 21 and the lower flap 22 are respectively spaced at a distance of 2mm from the inner walls of the notches 34 at both ends of the mounting plate body 31.

[0030] The middle flap 23 is L-shaped and includes a fixing plate 230 and a connecting plate 231. The fixing plate 230 is connected to the A-pillar lower reinforcing plate 2 through the connecting plate 231. The fixing plate 230 and the A-pillar lower reinforcing plate 2 are arranged parallel to each other. The connecting plate 231 is arranged perpendicular to the fixing plate 230, and the length of the connecting plate 231 is the same as the thickness of the mounting plate body 31. The middle flap 23 is used to fix the mounting plate body 31 and the A-pillar lower reinforcing plate 2.

[0031] When the hinge mounting plate 3 is fixed to the A-pillar lower reinforcing plate 2, the mounting plate body 31 is located between the fixing plate 230 and the A-pillar lower reinforcing plate 2, and the bottom surface of the fixing plate 230 is in contact with the top surface of the mounting plate body 31, thereby fixing the hinge mounting plate 3. At this time, the two sides of the connecting plate 231 are spaced at a set distance from the inner wall of the opening 35. In this embodiment, the two sides of the connecting plate 231 are spaced at 3mm from the inner wall of the opening 35, which facilitates the installation and adjustment of the car door.

[0032] By providing gaps between the upper and lower flaps 21 and the inner wall of the notch 34, and between the two sides of the connecting plate 231 and the inner wall of the opening 35, the necessary allowance is provided for door installation and adjustment, facilitating the adjustment of the door gap. Both the outer side panel 1 and the lower A-pillar reinforcement plate 2 have through holes 24, which correspond to the bolt mounting holes 33 on the hinge mounting plate 3. In use, the hinge is first placed on the outer side panel 1, with the bolt holes on the hinge corresponding to the through holes 24 on the outer side panel 1. The hinge mounting bolts pass through the hinge, the outer side panel 1, the lower A-pillar reinforcement plate 2, and the hinge mounting plate 3 in sequence, and are finally threaded with the nut for pre-locking. Since there is a gap between the notch 34 and the opening 35 on the hinge mounting plate 3 and the flap on the lower A-pillar reinforcement plate 2, the door can be adjusted to meet the requirements. After adjustment, the bolts are tightened. Since the bottom surface of the hinge mounting plate 3 has a serrated structure, the friction between it and the lower A-pillar reinforcement plate 2 is increased after tightening, thereby preventing the door from sliding down.

[0033] By creating notches and openings on the mounting plate body, and simultaneously installing an upper, lower, and middle flap on the A-pillar reinforcement plate, the upper and lower flaps correspond to the notches at both ends of the mounting plate body to limit the ends of the hinge mounting plate. The middle flap corresponds to the opening in the middle of the mounting plate body to fix the hinge mounting plate. This connection structure eliminates the need for welding the hinge mounting plate to surrounding components, thus eliminating the need for welding overlap edges and reinforcing features, reducing the weight of the hinge mounting plate. Furthermore, the hinge mounting plate can be fixed simply by installing the upper, lower, and middle flaps at the corresponding positions on the A-pillar or B-pillar of the vehicle, without requiring adaptation design for different vehicle models, thereby improving the applicability of the hinge mounting plate.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
