Description

Technical Field

[0001] This application relates to the technical field of automobile doors, and more particularly to a door hinge structure and a vehicle. Background Technology

[0002] In current automotive assembly processes, asymmetrical double-hinged doors, such as butterfly doors, typically use two pin-type hinges (upper and lower) to connect to the car body. In the welding workshop, the door is first positioned and fixed using tooling fixtures. Minor adjustments to the hinges are then made to ensure the precision of the gap and surface finish between the door and the side panel. Subsequently, the door needs to be removed in the final assembly workshop to assemble accessories such as glass, wiring harnesses, and interior panels, before finally being reassembled into the car body. There are two common secondary assembly methods: one is to loosen and retighten the hinge mounting bolts at the door or body end. However, the threads of these bolts are easily damaged after being tightened once, requiring replacement. Furthermore, repositioning requires re-using specialized tooling, which is time-consuming and labor-intensive. The other method is to directly pull out the hinge pins and reinsert them during reassembly. Theoretically, this maintains the original positional relationship. However, due to manufacturing and welding errors, the upper and lower hinge axes often intersect or become misaligned, preventing the pins from being inserted smoothly. In severe cases, the hinges must be removed and readjusted again, extending the assembly time and posing a risk of scratching the paint.

[0003] The aforementioned structural defects are particularly pronounced in unconventional car doors such as butterfly doors: during door movement, misalignment of the upper and lower hinges can cause door jamming, abnormal noises, vibrations, and even failure to close completely, directly impacting overall vehicle quality and user experience. Current technology can only barely align the two axes by simultaneously adjusting the installation angles of the upper and lower hinges and supplementing with overall translation, requiring meticulous adjustments that are inconvenient and reduce production efficiency. Furthermore, re-adjustment is required during disassembly and reinstallation, further reducing production efficiency. Therefore, there is an urgent need for a door hinge structure that reduces coaxiality requirements and simplifies the installation process. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a door hinge structure and vehicle, which combines a first hinge with a second hinge with a ball joint. This design allows for a wide tolerance range; simply aligning the first hinge axis close to the center of the second hinge ball eliminates the need for precise adjustments, enabling the door to open and close normally. This avoids repeated adjustments, saves time and effort, and improves production efficiency. It solves the technical problem of low production costs in existing technologies.

[0006] To achieve the above objectives, in a first aspect, this application provides a door hinge structure, comprising: A first hinge, comprising: A first mounting bracket, the first mounting bracket being used for mounting to the vehicle body; A first support rod is hinged to a first mounting base, and the first support rod and the first mounting base rotate around the hinge line. The first support rod is used to connect to the vehicle door. The second hinge includes: A second mounting bracket is used for mounting to the vehicle body; The second support rod is ball-jointed to the second mounting base.

[0007] Traditionally, two hinges, one axle-hinged and the other axle-hinged, are used in the technical solution. During installation, the axes of the two hinges must be collinear to achieve the desired door opening effect, requiring high precision. This application, however, uses a hinge consisting of one axle-hinged joint and one ball joint. The ball joint has a wider acceptable tolerance range; as long as the hinge axis of the first hinge is close to the center of the ball joint of the second hinge, it can achieve normal door opening without requiring particularly precise adjustments. This solves the technical problem of increased labor time due to repeated adjustments during door installation in existing technologies, thus improving production efficiency.

[0008] In some embodiments of this application, the hinge line in the first hinge passes through the center of the ball in the ball hinge of the second hinge.

[0009] In the technical solution, the ideal state is when the hinge axis of the first hinge passes through the center of the ball joint of the second hinge. The first hinge and the second hinge work together. While the first support rod rotates along the hinge line on the first mounting base, the second support rod also rotates along the hinge line on the first hinge on the second mounting base. This ensures that the rotation direction and angle of the first support rod and the second support rod are synchronized, and ensures that the door opens smoothly.

[0010] In some embodiments of this application, the first mounting base is provided with an adjustment mechanism, which is used to adjust the angle of the first mounting base on the vehicle body.

[0011] In this technical solution, when the hinge line of the first hinge deviates significantly from the center of the ball of the second hinge, the angle of the first mounting base can be adjusted by the first adjusting mechanism. This adjusts the angular direction of the hinge line in the first hinge, allowing it to pass through the center of the ball of the second hinge. This eliminates the need to disassemble and reinstall the first and second hinges, improving production efficiency.

[0012] In some embodiments of this application, a first groove is provided on the first mounting base; The adjustment mechanism includes: The first positioning pin is slidably connected to the first slide groove; the first positioning pin is used to be inserted into the vehicle body. A first locking component is used to fix the position of the first locating pin within the first slide groove.

[0013] In this technical solution, because the first locating pin is inserted into the vehicle body, the first mounting seat moves along the length of the first slide groove. During this movement, the first locating pin slides within the first slide groove. When the first mounting seat is adjusted to the appropriate position, i.e., when the hinge line of the first hinge passes through or approaches the center of the second hinge, the relative positions of the first locating pin and the first mounting seat are fixed by the first locking assembly, thus completing the adjustment of the first hinge. In the production process, the car door is first fixed to the vehicle body using the first and second hinges. During painting, the car door is removed, and after painting, it is reinstalled. This solution allows for adjustment via the first locating pin during the initial door installation, ensuring that the hinge line of the first hinge passes through or approaches the center of the second hinge. During the second installation after painting, because the position of the first locating pin is fixed by the first locking assembly, the position of the first hinge remains unchanged after the first locating pin is inserted into the vehicle body. Therefore, there is no need to readjust the position of the first hinge, further improving installation efficiency.

[0014] In some embodiments of this application, the first locking component includes: The first clamping plate is fixed to the first positioning pin and is located on the side of the first mounting seat facing the vehicle body. The first nut is threaded onto the side of the first locating pin away from the vehicle body.

[0015] In this technical solution, after adjusting the position of the first mounting base to a suitable angle, the first nut is tightened. The first nut and the first clamping plate hold both sides of the first mounting base, thereby fixing the relative position of the first mounting base and the first locating pin. Its structure is simple, easy to operate, and ensures efficient installation.

[0016] In some embodiments of this application, a second groove is provided on the first mounting base, and the length direction of the second groove is perpendicular to the first groove; The adjustment mechanism includes: The second positioning pin is slidably connected to the second slide groove; the second positioning pin is used to be inserted into the vehicle body. The second locking component is used to fix the position of the second locating pin in the second slide groove.

[0017] In the technical solution, the first positioning pin adjusts the position of the first hinge along the direction of the first slide groove, and the second positioning pin adjusts the position of the first hinge along the direction of the second slide groove. The position of the first hinge can be adjusted within a plane coordinate system through two mutually perpendicular directions, which allows for a wider range of adjustment of the angle of the hinge line in the first hinge. This facilitates quick adjustment of the position of the first hinge by the operator, improving both the adjustable range and production efficiency.

[0018] In some embodiments of this application, the first mounting base is provided with a through hole; The adjustment mechanism includes: A second positioning pin is inserted through the through hole, and the diameter of the second positioning pin is smaller than the diameter of the through hole. The second locking component is used to fix the position of the second locating pin within the through hole.

[0019] In this technical solution, the second locating pin can be freely adjusted within the through hole, and its position is not limited to a single direction. This makes it easier for personnel to adjust the position of the first hinge. Once the position of the first locating pin is adjusted, the operator can rotate the first mounting base around the first locating pin as a pivot until the axis of the first hinge passes through the center of the ball of the second hinge. Then, the first and second locking components can be used to fix the first and second locating pins respectively. This operation is quick and convenient, improving production efficiency.

[0020] In some embodiments of this application, the second locking component includes: The second clamping plate is fixed to the second positioning pin and is located on the side of the second mounting seat facing the vehicle body. The second nut is threaded onto the side of the second locating pin away from the vehicle body.

[0021] In this technical solution, after adjusting the position of the second mounting base to a suitable angle, the second nut is tightened. The second nut and the second clamping plate hold the two sides of the first mounting base, thereby fixing the relative position of the second mounting base and the second positioning pin. Its structure is simple, easy to operate, and ensures efficient installation.

[0022] In addition, this application also provides a vehicle, including: a body, a door, and a door hinge structure as described above; The first mounting base and the second mounting base are connected to the vehicle body; The first support rod and the second support rod are connected to the vehicle door.

[0023] In this technical solution, the car door can be installed onto the vehicle body via a first hinge and a second hinge. Furthermore, because the first hinge is a pivot hinge and the second hinge is a ball hinge, the positions of the first and second hinges can be quickly and easily adjusted, allowing the car door to be installed onto the vehicle body quickly and efficiently.

[0024] In some embodiments of this application, a first positioning hole and a second positioning hole are provided on the vehicle body, and the first positioning hole and the second positioning hole are used for the insertion of the first positioning pin and the second positioning pin.

[0025] In the technical solution, the first positioning hole and the second positioning hole provide insertion positions for the first positioning pin and the second positioning pin. When the car door needs to be disassembled and reinstalled (such as after the painting process), due to the presence of the first positioning hole and the second positioning hole, and because the relative positions of the first positioning pin and the second positioning pin have been fixed, it can be ensured that the position of the car door hinge structure remains consistent each time it is installed, without the need for readjustment. This effectively avoids problems such as mismatch in gaps and surface differences between the door and the car body caused by positional deviations, and ensures the assembly accuracy of the car door and the overall appearance quality of the vehicle.

[0026] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that in the automotive industry, the welding workshop first positions and fixes the car door using tooling fixtures, and then uses the slight adjustment of the hinges to ensure the accuracy of the gap and surface difference between the car door and the side panel; then the car door needs to be removed in the final assembly workshop to complete the assembly of accessories such as glass, wiring harness, and interior panels, and finally reinstalled on the car body.

[0031] In existing technologies, there are two common secondary assembly methods: one is to loosen and retighten the hinge mounting bolts at the door or body end, but the threads of the bolts are easily damaged after being tightened once, and new parts must be replaced. Moreover, special tooling must be used again for repositioning during reassembly, which is time-consuming and labor-intensive. The other is to directly pull out the hinge pin and insert it again during reassembly. Theoretically, the original positional relationship can be maintained. However, due to manufacturing and welding errors, the upper and lower hinge axes often cross or are misaligned, making it impossible to insert the pin smoothly. In severe cases, the hinge needs to be removed and readjusted again, which not only prolongs the cycle time but also poses a risk of scratching the paint.

[0032] Based on this, this application proposes a door hinge structure and vehicle. By combining the axial hinge of the first hinge with the ball hinge of the second hinge, a large tolerance range is achieved. Simply aligning the hinge axis of the first hinge close to the center of the ball of the second hinge allows the door to open and close normally without precise adjustments, avoiding repeated adjustments, saving time and effort, and improving production efficiency. This solves the technical problem of low production efficiency in existing technologies.

[0033] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0034] Please refer to all the accompanying drawings. In one illustrative embodiment of the door 10 hinge structure and vehicle of this application, the door 10 hinge structure includes a first hinge, and the door 10 is hinged to the vehicle body through the first hinge.

[0035] Specifically, the first hinge includes a first mounting base 100 and a first support rod 200. The first mounting base 100 is used for mounting to the vehicle body. The first support rod 200 is hinged to the first mounting base 100, and the first support rod 200 and the first mounting base 100 rotate about the hinge line. The first support rod 200 is used for connecting to the door 10.

[0036] In some embodiments, the door 10 hinge structure includes a second hinge, through which the door 10 is hinged to the vehicle body.

[0037] Specifically, the second hinge includes a second mounting base 900 and a second support rod 110. The second mounting base 900 is used for mounting to the vehicle body; the second support rod 110 is ball-jointed to the second mounting base 900.

[0038] In existing technologies, two hinges with a single hinge joint are used. During installation, it is necessary to ensure that the axes of the two hinges are collinear to achieve the desired door opening effect, which requires high precision. Specifically, the angles of the two hinges need to be adjusted first to make their hinge lines parallel, and then the positions of the hinges need to be adjusted to make their hinge lines collinear.

[0039] This application uses a hinge consisting of a shaft hinge and a ball hinge. The ball hinge has a larger acceptable tolerance range. As long as the hinge axis of the first hinge is close to the center of the ball of the second hinge, the door can be opened normally without particularly precise adjustment. This solves the technical problem in the prior art where repeated adjustments are required during door installation, which increases working time and improves production efficiency.

[0040] In some embodiments, a first hinge is provided at the front end of the door 10, and a second hinge is provided at the top end of the door 10.

[0041] In another embodiment, a second hinge is provided at the front end of the door 10, and a first hinge is provided at the top end of the door 10.

[0042] It is understandable that the positions of the first hinge (shaft-hinged) and the second hinge (ball-hinged) can be adjusted according to actual needs to facilitate production operations. However, it is preferable that the first hinge is located at the front end of the door 10 and the second hinge is located at the top of the door 10. Because the acceptable tolerance of the ball-hinged joint is relatively large, the second hinge does not require precise adjustment. Therefore, compared to the second hinge located at the top of the door, the first hinge located at the front end of the door 10 is more convenient for operators to operate, allowing them to operate while standing on the ground without having to operate in an uncomfortable posture, thus improving production efficiency.

[0043] In some embodiments, the hinge line of the first hinge passes through the center of the ball joint of the second hinge. Ideally, the hinge axis of the first hinge passes through the center of the ball joint of the second hinge. The first and second hinges work together, and while the first support rod 200 rotates along the hinge line on the first mounting base 100, the second support rod 110 also rotates along the hinge line on the first hinge on the second mounting base 900. This ensures that the rotation direction and angle of the first support rod 200 and the second support rod 110 are synchronized, ensuring smooth opening of the door.

[0044] It is understandable that the first hinge is a axial hinge, therefore the axis of rotation between the first support rod 200 and the first mounting base 100 is the hinge line of the first hinge. The second hinge, however, is a ball joint. The second support rod 110 or the second mounting base 900 will have a ball head, and a corresponding ball socket will be provided on the second support rod 110 or the second mounting base 900, allowing the ball head to rotatably connect within the ball socket. The center of the ball head is the center of the second hinge, which is the center point of the rotatable connection between the second support rod 110 and the second mounting base 900.

[0045] In some embodiments, the first mounting base 100 is provided with an adjustment mechanism for adjusting the angle of the first mounting base 100 on the vehicle body. When the hinge line of the first hinge deviates significantly from the center of the ball of the second hinge, the angle of the first mounting base 100 can be adjusted by the first adjustment mechanism, thereby adjusting the angular direction of the hinge line in the first hinge so that it can pass through the center of the ball of the second hinge. This eliminates the need to remove and reinstall the first and second hinges, improving production efficiency.

[0046] Understandably, given the relatively large acceptable tolerances of ball joints, the significance of setting an adjustment mechanism on the second hinge is minimal. However, the possibility of setting an adjustment mechanism on the second hinge cannot be ruled out. That is, it may include the following two situations: no adjustment structure is set on the first hinge, but an adjustment mechanism is set on the second hinge; or both the first and second hinges have adjustment mechanisms.

[0047] In some embodiments, a first mounting base 100 is provided with a first sliding groove 300. The adjustment mechanism includes a first positioning pin 500, which is slidably connected to the first sliding groove 300; the first positioning pin 500 is used to insert into the vehicle body. When the first hinge is adjusted, the first mounting base 100 is moved, at which time the first positioning pin 500 slides within the first sliding groove 300.

[0048] In some embodiments, the adjustment mechanism further includes a first locking component 700, which is used to fix the position of the first positioning pin 500 within the first slide groove 300.

[0049] Because the first locating pin 500 is inserted into the vehicle body, the first mounting seat 100 moves along the length of the first slide groove 300. At this time, the first locating pin 500 slides within the first slide groove 300. When the first mounting seat 100 is adjusted to the appropriate position, i.e., when the hinge line of the first hinge passes through or is close to the center of the second hinge, the relative position of the first locating pin 500 and the first mounting seat 100 is fixed by the first locking assembly 700, thus completing the adjustment of the first hinge. During production, the door 10 is first fixed to the vehicle body using the first hinge and the second hinge. The door 10 is removed during painting and reinstalled after painting is complete. With this solution, the first locating pin 500 can be used to adjust the door 10 during its initial installation, ensuring that the hinge line of the first hinge passes through or is close to the center of the second hinge. When reinstalling after disassembly and painting, the position of the first locating pin 500 is fixed by the first locking component 700. When reinstalling the first hinge, the position of the first hinge will not change after the first locating pin 500 is inserted into the vehicle body. Therefore, there is no need to readjust the position of the first hinge, which further improves the installation efficiency.

[0050] In some embodiments, the first groove 300 can be an oblong groove, which is easy to open, and when the first positioning pin 500 is located at the end of the first groove 300, the rounded corner of its end fits against the peripheral wall of the first positioning pin 500, reducing wear on the first positioning pin 500.

[0051] In some embodiments, the first locking assembly 700 includes a first clamping plate 701 and a first nut 703. The first clamping plate 701 is fixed to the first positioning pin 500 and is located on the side of the first mounting base 100 facing the vehicle body. The first nut 703 is threadedly connected to the side of the first positioning pin 500 away from the vehicle body.

[0052] During production, after adjusting the position of the first mounting base 100 to a suitable angle, the first nut 703 is tightened. The first nut 703 and the first clamping plate 701 clamp the two sides of the first mounting base 100, thereby fixing the relative position of the first mounting base 100 and the first positioning pin 500. Its structure is simple, easy to operate, and ensures high installation efficiency.

[0053] Specifically, the first clamping plate 701 and the first positioning pin 500 are integrally formed to ensure the strength between the first clamping plate 701 and the first positioning pin 500, and to ensure that the first clamping plate 701 will not fall off when the first nut 703 and the first clamping plate 701 clamp the first mounting base 100, thus ensuring the connection strength.

[0054] Understandably, the peripheral wall of the first locating pin 500 at the end away from the vehicle body has a threaded section for the first nut 703 to be threaded onto the first locating pin 500.

[0055] In some embodiments, the contact area between the first nut 703 and the first mounting base 100 is small, because a smaller contact area results in greater pressure. This is to prevent damage to the first nut 703 or the first mounting base 100 due to excessive pressure. The first locking assembly 700 also includes a first washer 702, which is sleeved on the first locating pin 500 and located on the side of the first mounting base 100 away from the vehicle body. The contact between the first washer 702 and the first mounting base 100 prevents damage to the first mounting base 100 or the first nut 703.

[0056] Specifically, the first pad 702 is located between the first nut 703 and the first mounting base 100. It can be understood that the contact area between the first pad 702 and the first mounting base 100 is greater than the contact area between the first nut 703 and the first mounting base 100. When locking the first locating pin 500, rotating the first nut 703 causes it to contact and move the first pad 702 closer to the first pressure plate. The first pressure plate and the first pad 702 together clamp the first mounting base 100, thereby locking the first locating pin 500 onto the first mounting base 100.

[0057] Furthermore, a washer is provided on the first nut 703, located between the first nut 703 and the first mounting base 100. The washer increases the contact area, thereby reducing pressure and preventing the first nut 703 from damaging the first mounting base 100. In addition, because the washer rotates relative to the first nut 703, when vibration occurs, the force can be dissipated solely through the rotation of the washer. This prevents the first nut 703 from loosening due to vibration; in other words, the washer serves an anti-loosening function.

[0058] Understandably, the first nut 703 has a slot that connects with the inside of the washer, thus securing the washer to the first nut 703. This structure can be a standard component structure.

[0059] In addition, the first nut 703 can also be integrally formed and connected with the washer.

[0060] In some embodiments, the first mounting base 100 has a second sliding groove, the length direction of which is perpendicular to the first sliding groove 300; the adjustment mechanism includes a second positioning pin 600, which is slidably connected to the second sliding groove; the second positioning pin 600 is used to insert into the vehicle body. When the first hinge is adjusted, the first mounting base 100 is moved, at which time the first positioning pin 500 slides in the first sliding groove 300, and the second positioning pin 600 slides in the second sliding groove. The mutually perpendicular first and second sliding grooves define a plane, allowing the first mounting base 100 to adjust its angle and position within the corresponding plane on the vehicle body.

[0061] In some embodiments, the adjusting mechanism further includes a second locking component 800, which is used to fix the position of the second locating pin 600 within the second slide groove. After the position of the first hinge is adjusted, the positions of the first locating pin 500 and the second locating pin 600 can be locked by the first locking component 700 and the second locking component 800. When the position of the first hinge is adjusted and then removed and reinstalled, because the positions of the first locating pin 500 and the second locating pin 600 on the first hinge have not changed, and the positions of the corresponding locating holes on the vehicle body also do not change, the position of the reinstalled first hinge will not change much, eliminating the need for repeated adjustments and improving production efficiency.

[0062] During production, the first positioning pin 500 adjusts the position of the first hinge along the direction of the first slide groove 300, and the second positioning pin 600 adjusts the position of the first hinge along the direction of the second slide groove. By adjusting the position of the first hinge in one plane coordinate through two mutually perpendicular directions, the angle of the hinge line in the first hinge can be adjusted within a larger range, which makes it easier for the operator to quickly adjust the position of the first hinge, thereby improving the adjustable range and production efficiency.

[0063] In another embodiment, the first mounting base 100 has a through hole 400. The adjustment mechanism includes a second positioning pin 600, which passes through the through hole 400, and the diameter of the second positioning pin 600 is smaller than the diameter of the through hole 400. When the first mounting base 100 is moved, the second positioning pin 600 moves within the through hole 400 because it is already inserted into the vehicle body.

[0064] Furthermore, the adjustment mechanism also includes a second locking component 800, which is used to fix the position of the second positioning pin 600 within the through hole 400. This ensures that the position of the first hinge will not change significantly when the hinge is reinstalled. Through this design, the second positioning pin 600 can be freely adjusted within the through hole 400, not limited to a single direction. Therefore, it is easier for personnel to adjust the position of the first hinge. Once the position of the first positioning pin 500 is adjusted, the operator can rotate the first mounting base 100 around the first positioning pin 500 until the axis of the first hinge passes through the center of the ball of the second hinge. Then, the first locking component 700 and the second locking component 800 can respectively fix the first positioning pin 500 and the second positioning pin 600, making the operation quick and convenient and improving production efficiency.

[0065] In some embodiments, the second locking assembly 800 includes a second clamping plate 801 and a second nut 803. The second clamping plate 801 is fixed to the second locating pin 600 and is located on the side of the second mounting base 900 facing the vehicle body. The second nut 803 is threadedly connected to the side of the second locating pin 600 away from the vehicle body. After adjusting the position of the second mounting base 900 to a suitable angle, the second nut 803 is tightened. The second nut 803 and the second clamping plate 801 clamp the two sides of the first mounting base 100, thereby fixing the relative position of the second mounting base 900 and the second locating pin 600. Its structure is simple, easy to operate, and ensures efficient installation.

[0066] Specifically, the second clamping plate 801 and the second positioning pin 600 are integrally formed to ensure the strength between the second clamping plate 801 and the second positioning pin 600, and to ensure that the second clamping plate 801 will not fall off when the second nut 803 and the second clamping plate 801 clamp the first mounting seat 100, thus ensuring the connection strength.

[0067] Understandably, the second locating pin 600 has a threaded section on the peripheral wall at the end away from the vehicle body, so that the second nut 803 can be threaded onto the second locating pin 600.

[0068] In some embodiments, the contact area between the second nut 803 and the first mounting base 100 is small, because a smaller contact area results in greater pressure. This is to prevent damage to the second nut 803 or the first mounting base 100 due to excessive pressure. The second locking assembly 800 also includes a second washer 802, which is sleeved on the second locating pin 600 and located on the side of the first mounting base 100 away from the vehicle body. The contact between the second washer 802 and the first mounting base 100 prevents damage to the first mounting base 100 or the second nut 803.

[0069] Specifically, the second pad 802 is located between the second nut 803 and the second mounting base 900. It can be understood that the contact area between the second pad 802 and the first mounting base 100 is greater than the contact area between the second nut 803 and the first mounting base 100. When locking the second locating pin 600, rotating the second nut 803 causes it to contact and move the second pad 802 closer to the second pressure plate. The second pressure plate and the second pad 802 together clamp the first mounting base 100, thereby locking the second locating pin 600 onto the first mounting base 100.

[0070] In some embodiments, the first hinge and the second hinge are connected to the vehicle body via a connector. The first locating pin 500 and the second locating pin 600 on the first hinge serve only a positioning function and are specifically secured by the connector.

[0071] Furthermore, the connectors include, but are not limited to, bolts, screws, and rivets. Commonly used standard parts are used for the connectors, reducing costs and facilitating procurement.

[0072] Correspondingly, the first mounting base 100 of the first hinge is provided with a first mounting hole 120, which is used for the connector to pass through and connect to the vehicle body.

[0073] Preferably, there are three first mounting holes 120. The principle of stability of triangles can make the connection between the first mounting seat 100 and the vehicle body more stable.

[0074] In addition, the second mounting base 900 of the second hinge is provided with a second mounting hole 130, which is used for the connector to pass through and connect to the vehicle body.

[0075] Preferably, there are three second mounting holes 130. The principle of stability of triangles can make the connection between the second mounting seat 900 and the vehicle body more stable.

[0076] Furthermore, this application also provides a vehicle, including a body, a door 10, and the door 10 hinge structure as described above. A first mounting base 100 and a second mounting base 900 are connected to the body. A first support rod 200 and a second support rod 110 are connected to the door 10. The door 10 can be mounted to the body via a first hinge and a second hinge. Because the first hinge is a pivot hinge and the second hinge is a ball hinge, the positions of the first and second hinges can be quickly and easily adjusted, allowing the door 10 to be quickly and efficiently mounted to the body.

[0077] Specifically, the first hinge is located at the front end of the door 10, and the second hinge is located at the rear end of the door 10. The reasons for this have already been explained above and will not be repeated here. It is understandable that the front end of the door 10 refers to the front part of the vehicle or body.

[0078] In some embodiments, a first positioning hole and a second positioning hole are provided on the vehicle body, for the insertion of a first positioning pin 500 and a second positioning pin 600. The first positioning hole and the second positioning hole provide insertion positions for the first positioning pin 500 and the second positioning pin 600. When the door 10 needs to be disassembled and reinstalled (such as after the painting process), due to the presence of the first positioning hole and the second positioning hole, and because the relative positions of the first positioning pin 500 and the second positioning pin 600 have been fixed, it can be ensured that the hinge structure of the door 10 is always installed in the same position without readjustment. This effectively avoids problems such as mismatch in gaps and surface differences between the door and the vehicle body caused by positional deviations, and ensures the assembly accuracy of the door 10 and the overall appearance quality of the vehicle.

[0079] In some embodiments, the vehicle body is also provided with connecting holes, the number and position of which are the same as the number of connecting parts and correspond one-to-one. The connecting holes are used for the connecting parts to pass through and connect, thereby realizing the installation of the first hinge and the second hinge to the vehicle body.

[0080] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
