Description

Technical Field

[0001] This utility model belongs to the field of vehicle body structure technology, specifically relating to an exposed hinge mounting structure for a car door and a vehicle. Background Technology

[0002] Currently, some vehicle models on the market use exposed hinges to connect the doors to the body in order to create a more rugged off-road appearance. However, the installation structure of exposed hinges does have a certain impact on the aesthetic appeal of the doors. This is because the adjustment of the door's position relative to the body depends on the position of the exposed hinges. The body end of the exposed hinge is connected to the body panel via fasteners that pass through it in the X or Y direction. This results in a lack of one direction for position adjustment between the body end of the exposed hinge and the body panel (if the fastener passes through it in the X direction, the body end can only be adjusted in the Y and Z directions; if the fastener passes through it in the Y direction, the body end can only be adjusted in the X and Z directions). Therefore, it is necessary to provide a position adjustment range between the door end of the exposed hinge and the door body.

[0003] Typically, the exposed hinge end of a car door can only be connected to the door body via fasteners along the Y-axis. Therefore, the door end can only be adjusted in the X and Z directions, not the Y-axis. Consequently, the exposed hinge body end must be connected to the body sheet metal via fasteners along the X-axis to allow for Y and Z-axis adjustment. X-axis adjustment is then performed using the door end. However, this method leads to uneven gaps between the door hinge arm and the hinge mounting area boundary (usually a recessed mounting surface) on the door's outer surface, affecting the door's aesthetic appearance and overall visual harmony. Therefore, there is an urgent need to optimize and improve the installation structure of exposed hinges. Utility Model Content

[0004] This utility model provides a door exposed hinge mounting structure and vehicle, which aims to improve the uniformity of the gap between the exposed hinge and the hinge mounting area boundary of the door, thereby enhancing the assembly coordination of the door exposed hinge and the overall exquisite appearance of the door.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: Firstly, an exposed hinge mounting structure for a car door is provided, including a car door body, a hinge seat, and a hinge body; a gap is formed between the car door body and its peripheral components, and the car door body and peripheral components together form a cavity with the car body sheet metal; the hinge seat is disposed in the cavity and connected to the car body sheet metal by a first fastener passing through in the Y direction; the hinge body includes a door-end hinge arm and a body-end hinge arm; wherein, the door-end hinge arm is fixedly connected to the outer surface of the car door body; the body-end hinge arm extends into the cavity and is connected to the hinge seat by a second fastener passing through in the X direction.

[0006] In conjunction with the first aspect, in one possible implementation, the hinge seat includes a first seat plate that is fitted to the body sheet metal along the Y direction, and a second seat plate that is fitted to the hinge arm at the body end along the X direction; the first seat plate is provided with a first connecting hole suitable for a first fastener to pass through, and the second seat plate is provided with a second connecting hole suitable for a second fastener to pass through; wherein, the first fastener has radial clearance in the first connecting hole and the second fastener has radial clearance in the second connecting hole.

[0007] In some embodiments, the inner surface of the body sheet metal is provided with a reinforcing plate, the reinforcing plate is aligned with the first seat plate along the Y direction, and the first fastener passes through the reinforcing plate.

[0008] For example, the door body includes an outer door panel, an inner door panel, and an outer panel reinforcing plate; wherein, the outer panel reinforcing plate is attached and fixed to the inner surface of the outer door panel, and one end of the outer panel reinforcing plate is bent inward and attached and fixed to the inner door panel; the door end hinge arm is connected to the outer door panel by a third fastener, and the third fastener passes through the outer panel reinforcing plate.

[0009] For example, the area corresponding to the outer panel of the car door and the outer panel reinforcement plate forms a concave surface, and the hinge arm at the car door end fits into the concave surface.

[0010] In one possible implementation, the concave surface has an avoidance groove near the edge of the seam; the door-end hinge arm and the body-end hinge arm are connected by a hinge shaft, which is located inside the avoidance groove.

[0011] In some embodiments, a clamping plate is provided between the concave surface and the outer reinforcing plate, and the edge of the clamping plate extends into the clearance groove to form a edging, which is folded over to cover the edge of the inner door panel.

[0012] For example, a connecting plate is attached and fixed to the inner side of the outer panel reinforcement plate. Both ends of the connecting plate are provided with threaded connection parts. Two third fasteners are spaced apart on the door hinge arm. The two third fasteners are respectively screwed to the threaded connection parts at both ends of the connecting plate.

[0013] For example, a pressure plate is pressed against the inner side of the connecting plate. The pressure plate is located between two threaded connection parts, and both ends of the pressure plate are attached and fixed to the outer plate reinforcing plate.

[0014] The beneficial effects of the exposed hinge mounting structure for car doors provided by this utility model are as follows: Compared with the prior art, in this utility model's exposed hinge mounting structure, the car door body and its adjacent peripheral parts, such as the sheet metal boundary of the adjacent car door, form a seam. A cavity capable of accommodating the hinge seat is formed between the inner side of the seam and the car body sheet metal. A first fastener passes through the hinge seat along the Y direction and is fixed to the car body sheet metal. A second fastener passes through the hinge seat along the X direction and is fixed to the door-end hinge arm of the hinge body. Loosening the first fastener allows for adjustment of the hinge seat's mounting position on the car body sheet metal in the X and Z directions using the assembly gap, thereby allowing the door-end hinge arm to... Along with the hinge base, the X and Z directions of the hinge arm can be adjusted. After adjustment, the first fastener can be re-secured. Similarly, by loosening the second fastener, the installation position of the door hinge arm on the hinge base can be adjusted in the Y and Z directions using the assembly gap. After adjustment, the second fastener can be re-secured. Without changing the fixed position of the door hinge arm on the outer surface of the door body, the door body can be adjusted in all directions. This ensures that the door hinge arm and the hinge installation area boundary on the outer surface of the door body always maintain a uniform installation gap, thereby improving the assembly coordination of the exposed hinges and the overall exquisite appearance of the door.

[0015] Furthermore, for the rear door assembled using the aforementioned exposed door hinge mounting structure, the B-pillar of the vehicle body, which connects to the hinge seat, can be hidden in the cavity inside the gap. The hinge seat, fixed to the B-pillar, connects to the hinge arm at the vehicle end. Compared to the existing technology that requires the exposed B-pillar to provide a hinge mounting position, this reduces one body gap, leaving only one gap between the front and rear doors, thereby further improving the overall appearance and refinement of the vehicle body.

[0016] The hinge seat utilizes a first seat plate that fits against the body sheet metal along the Y-axis. This not only improves the connection stability of the first fastener passing through the Y-axis to the first seat plate but also increases the stress-bearing area of ​​the body sheet metal, preventing stress concentration and deformation. A second seat plate is used to fix the hinge arm at the body end to the hinge seat via a second fastener passing through the X-axis. This increases the contact area between the hinge arm and the hinge seat, thereby improving the connection reliability of the hinge arm. Loosening the first fastener allows adjustment of the X-axis position of the first seat plate on the body sheet metal using the radial clearance between the first fastener and the first connecting hole. Z-axis position; Loosening the second fastener allows adjustment of the relative Y-axis and Z-axis positions of the second seat plate and the body-end hinge arm using the radial movement gap between the second fastener and the second connecting hole; Since the position adjustment of the first seat plate relative to the body sheet metal and the relative position adjustment of the second seat plate relative to the body-end hinge arm both ultimately manifest as the relative position adjustment of the door body relative to the body sheet metal, the position adjustment of the door body relative to the body sheet metal can be achieved by making all-round adjustments to the body-end connection position of the hinge body, thereby ensuring the uniformity of the gap between the door-end hinge arm and the hinge installation area boundary.

[0017] By setting a reinforcing plate on the inner surface of the body sheet metal, the structural strength of the mounting area of ​​the first seat plate on the body sheet metal can be improved, avoiding deformation or tearing of the body sheet metal under stress, thereby improving the connection reliability between the hinge seat and the body sheet metal, and further improving the stability and reliability of the door body connected to the body sheet metal through the hinge body.

[0018] Attaching an outer panel reinforcement plate to the inner side of the area where the door hinge arm is fixed to the outer panel improves the structural strength of the outer panel, preventing deformation or tearing under stress. Furthermore, placing the reinforcement plate on the inner side of the outer panel avoids exposing it and affecting the overall aesthetics. The bent end of the reinforcement plate can be fitted and fixed to the inner panel, increasing the connection strength between the two panels. The reinforcement plate also distributes stress from the outer panel to the inner panel, further enhancing its load-bearing capacity. The door hinge arm is then secured to the outer panel and reinforcement plate along the Y-axis using a third fastener, improving the connection strength and stability between the hinge arm and the outer panel.

[0019] A concave surface is provided on the outer door panel to allow the door hinge arm to be recessed and fixed on the outer door panel, thus preventing the door hinge arm from protruding excessively on the surface of the outer door panel. The boundary of this concave surface is the boundary of the hinge installation area. Since the position adjustment of the door body does not require changing the position of the door hinge arm on the concave surface, the door hinge arm can be first fixed to the concave surface during assembly, ensuring that the gap between the edge of the door hinge arm and the boundary of the concave surface is uniform. Then, the body hinge arm is installed. The assembly position accuracy of the door body is ensured by adjusting the Y-axis position of the body hinge arm and the hinge seat, and adjusting the X-axis and Z-axis positions of the hinge seat on the body sheet metal.

[0020] The concave edge is provided with a clearance groove to accommodate the hinge shaft, so that the hinge arm at the body end can extend into the cavity through the clearance groove. This helps to reduce the width of the gap while avoiding motion interference during the opening and closing of the door body, thereby improving the assembly coordination and appearance of the door.

[0021] The clamping plate set between the concave surface and the outer panel reinforcement plate can further enhance the structural strength of the connection area between the door hinge arm and the outer panel. On the other hand, the edge of the clamping plate can be folded and wrapped to fasten and fix the edge of the clearance groove and the edge of the inner panel, thereby improving the boundary structural strength of the clearance groove and preventing the clearance groove from tearing under stress.

[0022] The threaded connection parts at both ends of the connecting plate can be used to connect two third fasteners that pass through the hinge arm at the door end, so that the connecting plate is subjected to force as a whole and the force is evenly distributed. This avoids stress concentration and deformation of the outer door panel caused by the axial fastening force of the third fasteners, and can improve the connection structure strength of the hinge arm at the door end.

[0023] By setting a pressure plate on the inner side of the connecting plate and attaching the two ends of the pressure plate to the outer plate reinforcement plate, the fastening force of the third fastener can be evenly transmitted to the outer plate reinforcement plate through the connecting plate and the pressure plate, further avoiding the problem of stress concentration. On this basis, setting a pressure plate can provide support force to the outer door panel in the Y direction, thereby preventing the outer door panel from collapsing or bulging outward due to stress in the Y direction.

[0024] Secondly, this utility model embodiment also provides a vehicle including the above-mentioned exposed door hinge mounting structure.

[0025] The beneficial effects of the vehicle provided by this utility model are as follows: Compared with the prior art, the vehicle of this utility model adopts the above-mentioned exposed door hinge installation structure. The door body and its adjacent peripheral parts, such as the sheet metal boundary of the adjacent door, form a gap. A cavity that can accommodate the hinge seat is formed between the inner side of the gap and the body sheet metal. The first fastener passes through the hinge seat along the Y direction and is fixed to the body sheet metal. The second fastener passes through the hinge seat along the X direction and is fixed to the door end hinge arm of the hinge body. Loosening the first fastener allows the installation position of the hinge seat on the body sheet metal to be adjusted in the X and Z directions using the assembly gap, thereby allowing the door end hinge arm to move with the body. The hinge seat can be adjusted in both the X and Z directions. After adjustment, the first fastener can be re-secured. Similarly, by loosening the second fastener, the installation position of the door hinge arm on the hinge seat can be adjusted in the Y and Z directions using the assembly gap. After adjustment, the second fastener can be re-secured. Without changing the fixed position of the door hinge arm on the outer surface of the door body, the door body can be adjusted in all directions. This ensures that there is always a uniform installation gap between the door hinge arm and the hinge installation area boundary on the outer surface of the door body, thereby improving the assembly coordination of the exposed hinges and the overall exquisite appearance of the door.

[0026] For the rear door assembled using the aforementioned exposed hinge mounting structure, the B-pillar of the vehicle body, which connects to the hinge seat, can be hidden in the cavity inside the gap. The hinge seat, fixed to the B-pillar, connects to the hinge arm at the vehicle body end. Compared to the existing technology that requires the exposed B-pillar to provide a hinge mounting position, this reduces one body gap, leaving only one gap between the front and rear doors, thereby further improving the overall appearance and refinement of the vehicle body.

In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0036] Please refer to the following: Figures 1 to 6The exposed hinge mounting structure for a car door provided by this utility model is described below. The exposed hinge mounting structure includes a car door body 10, a hinge seat 20, and a hinge body 30. A gap 100 is formed between the car door body 10 and its peripheral components 80, and the car door body 10 and the peripheral components 80 together form a cavity 400 with the body sheet metal 40. The hinge seat 20 is disposed within the cavity 400 and connected to the body sheet metal 40 via a first fastener 50 extending in the Y direction. The hinge body 30 includes a door-end hinge arm 31 and a body-end hinge arm 32. The door-end hinge arm 31 is fixedly connected to the outer surface of the car door body 10. The body-end hinge arm 32 extends into the cavity 400 and is connected to the hinge seat 20 via a second fastener 60 extending in the X direction.

[0037] It should be understood that the exposed hinge mounting structure provided in this embodiment satisfies the installation requirements of all front and rear doors on both sides of the vehicle. Specifically, for the installation of the front door, a gap 100 is formed between the door body 10 and the sheet metal boundary located on the front side of the front door, and the hinge seat 20 is fixed to the lower section of the body sheet metal 40. For the installation of the rear door, the aforementioned peripheral component 80 can be understood as the front door, that is, a gap 100 is formed between the door body 10 and the rear boundary of the front door. At this time, the body B-pillar is recessed and hidden inside the gap 100 and serves as the mounting base for the hinge seat 20.

[0038] In this embodiment, both the first fastener 50 and the second fastener 60 can be bolt and nut pairs. Both the first fastener 50 and the second fastener 60 pass through the hinge seat 20 with a clearance fit, thereby allowing the first fastener 50 and the second fastener 60 to swing relative to the hinge seat 20 after being loosened. Since the first fastener 50 is inserted along the Y direction, the hinge seat 20 can be adjusted in the X and Z directions relative to the body sheet metal 40 after it is loosened. The second fastener 60 is inserted along the X direction, so the body-end hinge arm 32 can be adjusted in the Y and Z directions relative to the hinge seat 20 (also relative to the body sheet metal 40) after it is loosened. It can be seen that by using the connection and orientation of the first fastener 50 and the second fastener 60, the X, Y, and Z directions of the body-end hinge arm 32 can be adjusted in all directions, thereby achieving adjustable assembly position of the door body 10 on the basis of the fixed connection between the door-end hinge arm 31 and the door body 10.

[0039] Compared with the prior art, the exposed hinge mounting structure of the car door provided in this embodiment forms a gap 100 between the door body 10 and its adjacent peripheral parts 80, such as the sheet metal boundary of the adjacent door. A cavity 400 capable of accommodating the hinge seat 20 is formed between the inner side of the gap 100 and the body sheet metal 40. The first fastener 50 passes through the hinge seat 20 in the Y direction and is fixed to the body sheet metal 40. The second fastener 60 passes through the hinge seat 20 in the X direction and is fixed to the door end hinge arm 31 of the hinge body 30. By loosening the first fastener 50, the mounting position of the hinge seat 20 on the body sheet metal 40 can be adjusted in the X and Z directions using the assembly gap, so that the door end hinge arm 31 moves with the hinge seat. The first fastener 50 can be re-secured after the position of the door hinge arm 31 on the hinge seat 20 is adjusted in both the X and Z directions by loosening the second fastener 60 and using the assembly gap. After adjustment, the second fastener 60 can be re-secured. The door body 10 can be fully adjusted in all directions without changing the fixed position of the door hinge arm 31 on the outer surface of the door body 10. This ensures that the door hinge arm 31 and the hinge installation area boundary on the outer surface of the door body 10 always maintain a uniform installation gap, thereby improving the assembly coordination of the exposed hinges and the overall exquisite appearance of the door.

[0040] Furthermore, for the rear door assembled using the aforementioned exposed hinge mounting structure, the B-pillar of the vehicle body, which is connected to the hinge seat 20, can be hidden in the cavity 400 inside the gap 100. The hinge seat 20, which is fixed to the B-pillar of the vehicle body, is connected to the hinge arm 32 at the end of the vehicle body. Compared with the prior art, which requires the exposed B-pillar of the vehicle body to provide a hinge mounting position, one body gap 100 can be reduced, leaving only one gap 100 between the front door and the rear door. This can further improve the overall appearance and refinement of the vehicle body.

[0041] In some embodiments, see Figures 2 to 6 The hinge seat 20 includes a first seat plate 21 that is fitted to the body sheet metal 40 along the Y direction, and a second seat plate 22 that is fitted to the hinge arm 32 at the body end along the X direction; the first seat plate 21 is provided with a first connecting hole 211 suitable for the first fastener 50 to pass through, and the second seat plate 22 is provided with a second connecting hole 221 suitable for the second fastener 60 to pass through; wherein, the first fastener 50 has radial movement clearance in the first connecting hole 211 and the second fastener 60 has radial movement clearance in the second connecting hole 221.

[0042] Specifically, the hinge seat 20 can be an L-shaped bent structure. One bent portion serves as the first seat plate 21, which fits against the body sheet metal 40 along the Y direction. This not only improves the connection stability of the first fastener 50 passing through the Y direction to the first seat plate 21, but also increases the stress-bearing area of ​​the body sheet metal 40, preventing stress concentration and deformation. The other bent portion serves as the second seat plate 22, which is fixedly connected to the body end hinge arm 32 by the second fastener 60 passing through the X direction. This increases the contact area between the body end hinge arm 32 and the hinge seat 20, thereby improving the connection reliability of the body end hinge arm 32. Loosening the first fastener 50 allows for adjustment using the radial movement clearance between the first fastener 50 and the first connecting hole 211. The X and Z directions of the first seat plate 21 on the body sheet metal 40; by loosening the second fastener 60, the radial movement gap between the second fastener 60 and the second connecting hole 221 can be used to adjust the relative positions of the second seat plate 22 and the body end hinge arm 32 in the Y and Z directions; since the position adjustment of the first seat plate 21 relative to the body sheet metal 40 and the relative position adjustment of the second seat plate 22 relative to the body end hinge arm 32 are ultimately reflected in the relative position adjustment of the door body 10 relative to the body sheet metal 40, the position adjustment of the door body 10 relative to the body sheet metal 40 can be achieved by making all-round adjustments to the body end connection position of the hinge body 30, thereby ensuring the uniformity of the gap between the door end hinge arm 31 and the hinge installation area boundary.

[0043] It should be noted that, as Figure 2 and Figure 3 As shown, the inner surface of the aforementioned body sheet metal 40 is provided with a reinforcing plate 41, which is aligned with the first seat plate 21 along the Y direction, and the first fastener 50 passes through the reinforcing plate 41.

[0044] The reinforcing plate 41 can be glued or welded to the inner surface of the body sheet 40. Of course, considering that the first fastener 50 can pass through the reinforcing plate 41 to fix the reinforcing plate 41 to the body panel, the connection between the reinforcing plate 41 and the body sheet 40 can also be solely dependent on the first fastener 50. By setting the reinforcing plate 41, the structural strength of the mounting area of ​​the first seat plate 21 on the body sheet 40 can be improved, avoiding deformation or tearing of the body sheet 40 under stress, thereby improving the connection reliability between the hinge seat 20 and the body sheet 40, and further improving the stability and reliability of the door body 10 connected to the body sheet 40 through the hinge body 30.

[0045] As one specific embodiment of the aforementioned door body 10, please refer to Figure 5The door body 10 includes an outer door panel 11, an inner door panel 12, and an outer panel reinforcing plate 13; wherein, the outer panel reinforcing plate 13 is attached and fixed to the inner surface of the outer door panel 11, and one end of the outer panel reinforcing plate 13 is bent inward and attached and fixed to the inner door panel 12; the door end hinge arm 31 is connected to the outer door panel 11 by a third fastener 70, and the third fastener 70 passes through the outer panel reinforcing plate 13.

[0046] The basic structure of this door body 10 is similar to that of existing door structures, consisting of an outer door panel 11 and an inner door panel 12 that are snapped together at the edges. In this embodiment, an outer door reinforcing plate 13 is provided on the outer door panel 11 corresponding to the installation position of the door end hinge arm 31. The outer door reinforcing plate 13 can be glued or welded to the inner surface of the outer door panel 11. The provision of the outer door reinforcing plate 13 can improve the structural strength of the outer door panel 11, preventing the outer door panel 11 from deforming or tearing under stress. At the same time, the outer door reinforcing plate 13 is located on the inner side of the outer door panel 11, which not only prevents the outer door reinforcing plate 13 from being exposed and affecting the appearance, but also allows the bent end of the outer door reinforcing plate 13 to be fitted and fixed to the inner door panel 12, thereby improving the connection strength between the outer door panel 11 and the inner door panel 12. Furthermore, the outer door reinforcing plate 13 disperses and transmits the force on the outer door panel 11 to the inner door panel 12, further improving the stress performance of the outer door panel 11. Since no additional position adjustment function is required between the door hinge arm 31 and the outer door panel 11, the third fastener 70 can be a centering bolt. The centering bolt can ensure the uniqueness of the connection position between the door hinge arm 31 and the outer door panel 11, thereby improving the stability of the door hinge arm 31 being fastened together with the outer door panel 11 and the outer panel reinforcing plate 13 along the Y direction through the third fastener 70. This ensures the uniformity of the gap between the hinge installation area boundary of the door hinge arm 31 and the outer door panel 11, and enhances the exquisite appearance of the exposed door hinge assembly.

[0047] Specifically, such as Figure 4 and Figure 5As shown, in this embodiment, the area corresponding to the outer door panel 11 and the outer panel reinforcing plate 13 forms a concave surface 111, and the door end hinge arm 31 is in contact with the concave surface 111. A concave surface 111 is provided on the outer door panel 11 to allow the door-end hinge arm 31 to be recessed and fixed on the outer door panel 11, thereby avoiding excessive protrusion of the door-end hinge arm 31 on the surface of the outer door panel 11. The boundary of the concave surface 111 is the boundary of the hinge installation area. Since the position adjustment of the door body 10 does not require changing the position of the door-end hinge arm 31 on the concave surface 111, the door-end hinge arm 31 can be fixed to the concave surface 111 first during assembly to ensure that the gap between the edge of the door-end hinge arm 31 and the boundary of the concave surface 111 is uniform. Then, the body-end hinge arm 32 is installed. The assembly position accuracy of the door body 10 is ensured by adjusting the Y-axis position of the body-end hinge arm 32 and the hinge seat 20 and adjusting the X-axis and Z-axis positions of the hinge seat 20 on the body sheet metal 40.

[0048] For some possible implementations, please refer to [link / reference]. Figure 4 The concave surface 111 has a clearance slot 112 near the edge of the gap 100. The door-end hinge arm 31 and the body-end hinge arm 32 are connected by a hinge shaft 33, which is located within the clearance slot 112. The clearance slot 112 at the edge of the concave surface 111 accommodates the hinge shaft 33, allowing the body-end hinge arm 32 to extend into the cavity 400 through the clearance slot 112. This helps to reduce the width of the gap 100 while avoiding motion interference during the opening and closing of the door body 10, thereby improving the assembly coordination and appearance of the door.

[0049] In some embodiments, such as Figure 5 As shown, a clamping plate 14 is provided between the concave surface 111 and the outer panel reinforcing plate 13. The edge of the clamping plate 14 extends into the clearance groove 112 to form a edging 141, which folds over and covers the edge of the inner door panel 12. The clamping plate 14 provided between the concave surface 111 and the outer panel reinforcing plate 13 can, on the one hand, further improve the structural strength of the connection area between the door hinge arm 31 and the outer door panel 11, and on the other hand, the folded edging 141 of the clamping plate 14 can fasten and fix the edge of the clearance groove 112 and the edge of the inner door panel 12, thereby improving the boundary structural strength of the clearance groove 112 and preventing the clearance groove 112 from tearing under stress.

[0050] As a specific connection method of the door hinge arm 31, combined with Figures 2 to 5 It is understood that a connecting plate 15 is attached and fixed to the inner side of the outer panel reinforcing plate 13. Both ends of the connecting plate 15 are provided with threaded connection parts 151. Two third fasteners 70 are spaced apart on the door hinge arm 31. The two third fasteners 70 are respectively screwed to the threaded connection parts 151 at both ends of the connecting plate 15.

[0051] Specifically, the threaded connection part 151 can be a cylinder integrally formed on the end of the connecting plate 15. A threaded hole is provided at the center of the cylinder to engage with the third fastener 70. This ensures the thread engagement length and the axial load-bearing capacity of the third fastener 70 and the threaded connection part 151, preventing thread slippage and connection failure. On this basis, the threaded connection parts 151 at both ends of the connecting plate 15 can respectively connect the two third fasteners 70 passing through the door hinge arm 31, so that the connecting plate 15 is subjected to force as a whole and the force is evenly distributed to the outer plate reinforcing plate 13. This avoids stress concentration and deformation of the door outer plate 11 and the outer plate reinforcing plate 13 due to the axial fastening force of the third fasteners 70, thereby improving the connection structure strength of the door hinge arm 31.

[0052] Furthermore, such as Figure 5 As shown, a pressure plate 16 is pressed against the inner side of the connecting plate 15. The pressure plate 16 is located between the two threaded connection parts 151, and both ends of the pressure plate 16 are attached and fixed to the outer plate reinforcing plate 13. The two ends of the pressure plate 16 can be welded or bonded to the outer plate reinforcing plate 13. The pressure plate 16 and the connecting plate 15 form a cross-over joint, so that the pressure plate 16 presses the connecting plate 15 tightly onto the outer plate reinforcing plate 13. This allows the fastening force of the third fastener 70 to be evenly transmitted to the outer plate reinforcing plate 13 through the connecting plate 15 and the pressure plate 16, further avoiding the problem of stress concentration. On this basis, the pressure plate 16 can provide support force to the outer door panel 11 in the Y direction, thereby preventing the outer door panel 11 from collapsing or bulging outward due to force.

[0053] Based on the same inventive concept, combined with Figures 1 to 6 It is understood that this application also provides a vehicle including the above-described exposed door hinge mounting structure.

[0054] Compared with the prior art, the vehicle provided by this utility model adopts the above-mentioned exposed door hinge installation structure. The door body 10 and its adjacent peripheral parts 80, such as the sheet metal boundary of the adjacent door, form a gap 100. A cavity 400 that can accommodate the hinge seat 20 is formed between the inner side of the gap 100 and the body sheet metal 40. The first fastener 50 passes through the hinge seat 20 along the Y direction and is fixed to the body sheet metal 40. The second fastener 60 passes through the hinge seat 20 along the X direction and is fixed to the door end hinge arm 31 of the hinge body 30. By loosening the first fastener 50, the installation position of the hinge seat 20 on the body sheet metal 40 can be adjusted in the X and Z directions using the assembly gap, thereby allowing the door end hinge arm 31 to be adjusted. Along with the hinge base 20, the X and Z directions of the hinge arm 31 can be adjusted. After adjustment, the first fastener 50 can be re-secured. Similarly, by loosening the second fastener 60, the installation position of the door-end hinge arm 31 on the hinge base 20 can be adjusted in the Y and Z directions using the assembly gap. After adjustment, the second fastener 60 can be re-secured. Without changing the fixed position of the door-end hinge arm 31 on the outer surface of the door body 10, the door body 10 can be adjusted in all directions. This ensures that the door-end hinge arm 31 and the hinge installation area boundary on the outer surface of the door body 10 always maintain a uniform installation gap, thereby improving the assembly coordination of the exposed hinges and the overall exquisite appearance of the door.

[0055] For the rear door assembled using the above-mentioned exposed door hinge mounting structure, the body panel 40, which is connected to the hinge seat 20, can be hidden in the cavity 400 inside the gap 100. It is connected to the body hinge arm 32 by the hinge seat 20 fixed on the body B-pillar. Compared with the existing technology that requires the body B-pillar to be exposed to provide a hinge mounting position, one body gap 100 can be reduced, and only one gap 100 between the front door and the rear door needs to be retained, thereby further improving the overall appearance and refinement of the vehicle body.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
