For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0045] The present application provides a hinge 100, which is used to connect a vehicle door and a vehicle body. The hinge 100 can realize the opening and closing of the vehicle door. The vehicle door and the vehicle body can be connected by only one hinge 100, which has a simple layout process and occupies a small space. Figures 1 to 3 As shown, the hinge 100 includes a hinge axis 110 , a first hinge leaf 120 and a second hinge leaf 130 .

[0046] The first hinge 120 is used to connect the vehicle door and can be fixedly connected to the vehicle door. The first hinge 120 is provided with a weight-reducing hole 1211, which is used to reduce the weight of the first hinge 120, thereby reducing the resistance when the vehicle door is opened and closed, and improving the smoothness and comfort of the operation of the driver and passengers.

[0047] The second hinge 130 is used to connect the vehicle body. One side of the second hinge 130 can be fixedly connected to the vehicle body. The first hinge 120 is rotatably connected to the second hinge 130 through the hinge shaft 110. The first hinge 120 and the second hinge 130 can be connected through the hinge shaft 110 to achieve the rotatable connection between the first hinge 120 and the second hinge 130. Specifically, the first hinge 120 and the second hinge 130 are both provided with an axis hole connected to the hinge shaft 110. The axis holes on the first hinge 120 and the second hinge 130 can be aligned and fixed by a tool, and the hinge shaft 110 is inserted into the axis hole for riveting and fixing. The first hinge 120 can rotate relative to the second hinge 130 around the hinge shaft 110.

[0048] The first hinge leaf 120 of the hinge 100 is fixedly connected to the vehicle door, and the second hinge leaf 130 is fixedly connected to the vehicle body. Under the action of the hinge 100, the vehicle door can rotate relative to the vehicle body along the axis of the hinge 100, that is, the vehicle door can rotate along the axial direction of the hinge shaft 110, so that the vehicle door can be opened and closed. It can be understood that the hinge 100 has an open state and a closed state. When the vehicle door is closed, the hinge 100 is in a closed state, and when the vehicle door is opened, the hinge 100 is in an open state.

[0049] The hinge 100 is a mechanical device for opening and closing the door, and requires the normal function of the door. The hinge 100 provided in the present application is designed with a weight-reducing hole 1211 on the first hinge leaf 120, which can reduce the weight of the first connecting arm 121, reduce the resistance when opening and closing the door, and improve the smoothness and comfort of the operation for the driver and passengers.

[0050] In a possible implementation, the first hinge 120 includes a first connecting arm 121, and the first connecting arm 121 is rotatably connected to the second hinge 130 through the hinge shaft 110. The first connecting arm 121 is rotatably connected to the hinge shaft 110, and the hinge shaft 110 is rotatably connected to the first connecting arm 121 and the second hinge 130, and the first connecting arm 121 is located on the side of the second hinge 130 away from the fixed connection with the vehicle body. The first connecting arm 121 can support the vehicle door and is connected to the second hinge through the hinge shaft. The hinge shaft 110 is rotatably connected to the first hinge 120 and the second hinge 130.

[0051] In a possible implementation, the length of the hinge shaft 110 can be designed to be between 180 mm and 210 mm. In some embodiments, the length of the hinge shaft 110 can be designed to be 180 mm, or 200 mm, or 210 mm. The longer hinge shaft 110 can bear a greater weight, can better support the weight of the door, and reduce the bending or deformation caused by the weight of the door. The diameter of the hinge shaft 110 can be in the range of 10 mm to 12 mm. For example, the diameter of the hinge shaft 110 can be 11 mm.

[0052] In one possible implementation, see Figure 1 As shown, the hinge 100 includes a bushing 140, which is embedded in the first hinge 120 and sleeved on the hinge shaft 110. For example, four bushings 140 may be sleeved on the hinge shaft 110, that is, the bushing 140 is located between the first hinge 120 and the hinge shaft 110. The outer surface of the hinge shaft 110 contacts the inner surface of the bushing 140. The bushing 140 may be made of a wear-resistant material, so that the bushing 140 is not easy to wear under the condition of frequent opening and closing of the door, and the hinge shaft 110 and the bushing 140 are not easy to loosen and cause abnormal noise. It can be understood that, considering the actual process and the test verification of the torque and durability, the bushing 140 can be replaced with a bushing 140 of other number or size, or the bushing 140 can be set on the second hinge 130.

[0053] In a possible implementation, the first connecting arm 121 is an arc-shaped structure. The weight-reducing hole 1211 includes a first weight-reducing hole 1211a, which is a through hole that passes through the first connecting arm 121 along the bending direction of the first connecting arm 121. Figure 2 and Figure 3 As shown, the first connecting arm 121 has an arc-shaped structure, and the bending direction refers to the direction of the arc formed by the first connecting arm 121 along its arc-shaped structure. The opening shape of the first weight-reducing hole 1211a is curved. The first weight-reducing hole 1211a may include a through hole, which is a hole passing through the first connecting arm 121, and the through hole passes through the first connecting arm 121 along the bending direction of the first connecting arm 121. The first weight-reducing hole 1211a in the shape of a through hole can help reduce the weight of the first connecting arm 121.

[0054] In a possible implementation manner, the weight-reducing hole 1211 includes a second weight-reducing hole 1211b along the axial direction of the hinge axis. Figure 3 and Figure 4As shown, the first connecting arm 121 is further provided with a second weight-reducing hole 1211b, and the second weight-reducing hole 1211b is used to further reduce the weight of the first connecting arm 121.

[0055] In one embodiment, see Figure 2 , Figure 3 and Figure 4 As shown, the first connecting arm 121 has two side arms 1212, and the two side arms 1212 are arranged opposite to each other. The two side arms are provided with second weight reducing holes 1211b. The number of the second weight reducing holes 1211b can be multiple. For example, four second weight reducing holes 1211b can be respectively provided on the two oppositely arranged side arms 1212. The shapes of the second weight reducing holes 1211b on the two side arms 1212 can be the same or different. The through hole (i.e., the first weight reducing hole 1211a) is located between the two side arms 1212.

[0056] In a possible embodiment, the second weight-reducing hole 1211b is a blind hole, that is, the second weight-reducing hole 1211b does not penetrate the first connecting arm 121 along the axial direction of the hinge shaft 110. The second weight-reducing hole 1211b is set as a blind hole, which can reduce the weight of the first connecting arm 121 while ensuring the structural strength of the first connecting arm 121, so that the hinge can reduce the resistance when the door is opened and closed, improve the smoothness and comfort of the driver and passengers' operation, and have higher structural rigidity, avoiding excessive bending or deformation of the first connecting arm 121 under the action of the gravity of the door or other external forces, thereby maintaining the normal working state of the hinge.

[0057] In one possible implementation, see Figures 3 to 5 As shown, the first hinge 120 also includes a first mounting seat 122, the first mounting seat 122 is used to be fixedly connected to the vehicle door, the first connecting arm 121 is fixedly connected to the first mounting seat 122, the first connecting arm 121 can be integrally formed with the first mounting seat 122, and the first connecting arm 121 can also be fixedly connected to the first mounting seat 122 by welding or riveting. The weight-reducing hole 1211 includes a third weight-reducing hole 1211c along the thickness direction of the first mounting seat 122, and the first mounting seat 122 is provided with a third weight-reducing hole 1211c, and the third weight-reducing hole 1211c is used to reduce the weight of the first mounting seat 122, thereby reducing the overall weight of the hinge 100, reducing the resistance when the vehicle door is opened and closed, and improving the smoothness and comfort of the driver and passenger operation. The third weight-reducing hole 1211c can be a blind hole or a through hole.

[0058] In one embodiment, see Figure 5As shown, three third weight-reducing holes 1211c are provided on the first mounting seat 122, wherein the shapes of the three third weight-reducing holes 1211c may be the same or different, and the first hole weight-reducing hole 1211, the second weight-reducing hole 1211b and the third weight-reducing hole 1211c can reduce the weight of the hinge 100 while ensuring the load requirements of the hinge 100 and the sinking stiffness requirements of the door, and can reduce the weight within the range of 15% to 25%, meeting the lightweight requirements.

[0059] In a possible implementation, the depth of the weight-reducing holes 1211, including the first weight-reducing holes 1211a, the second weight-reducing holes 1211b, and the third weight-reducing holes 1211c, can be in the range of 12 mm to 22 mm. The wall thickness of the weight-reducing holes 1211, including the first weight-reducing holes 1211a, the second weight-reducing holes 1211b, and the third weight-reducing holes 1211c, can be in the range of 7 mm to 10 mm.

[0060] In a possible implementation, the first mounting seat 122 is provided with mounting holes, and the mounting holes are used to fix the first mounting seat 122 to the vehicle door. The mounting holes include a first mounting hole 1221 and a second mounting hole 1222. The number of the second mounting holes 1222 is multiple, and the multiple second mounting holes 1222 are distributed around the first mounting hole 1221. The line connecting the multiple second mounting holes 1222 and the first mounting hole 1221 is "Y" shaped.

[0061] In one embodiment, see Figure 5 As shown, the first mounting seat 122 is provided with a first mounting hole 1221 and three second mounting holes 1222, wherein the first mounting hole 1221 is located in the middle of the first mounting seat 122, and the second mounting holes 1222 are distributed around the first mounting hole 1221, for example, they can be respectively located at three corners of the first mounting seat 122 away from the first connecting arm 121. The three second mounting holes 1222 are evenly distributed around the first mounting hole 1221, and the three second mounting holes 1222 are respectively set at a first distance from the first mounting hole 1221, and the first distance is in the range of 85 mm to 90 mm. The connecting line of multiple second mounting holes 1222 and the first mounting hole 1221 is in a "Y" shape, so that the first mounting holes 1221 and the second mounting holes 1222 are distributed in a "Y"-shaped structure on the first mounting seat 122. The vehicle door is also designed with a first through hole, and the first mounting hole 1221 and the second mounting hole 1222 match the first through hole on the vehicle door. After a fixing structure such as a pin or a screw passes through the first mounting hole 1221, the second mounting hole 1222 and the first through hole on the vehicle door to fix the hinge 100 to the vehicle door, the first mounting seat 122 can bear the weight of the vehicle door more evenly, ensure the stable support of the hinge 100 to the vehicle door, and ensure the sinking stiffness of the vehicle door.

The hole structure 153 is provided on the second mounting seat 131. When the door is closed, the first connecting arm 121 is at least partially located in the hole structure 153. When the door is opened, the first connecting arm 121 may be located outside the hole structure 153.

[0063] See also Figure 6 As shown, a hole structure 153 is provided on the second mounting seat 131, and the hole structure 153 has an opening 153a, and the opening 153a can be located on the side of the second mounting seat 131 that does not contact the vehicle body. The first connecting arm 121 is rotatably connected to the second hinge 130 through the hinge shaft 110. When the first connecting arm 121 rotates relative to the second mounting seat 131, when the door is closed, at least part of it is located in the hole structure 153. The hole structure 153 is used to avoid the first connecting arm 121, so as to prevent the first connecting arm 121 from colliding with the second mounting seat 131 when the first connecting arm 121 rotates relative to the second mounting seat 131. At the same time, the hole structure 153 can also reduce the weight of the hinge 100. Exemplarily, the shape of the hole structure 153 can be a rounded rectangle, and the depth of the hole structure 153 can be in the range of 12 mm to 22 mm.

Specifically, see Figure 3As shown, the first connecting arm 121 with an arc structure has two ends, one end of which is rotatably connected to the hinge shaft 110, and the other end is fixedly connected to the first mounting seat 122. The first connecting arm 121 has a height and a length. The length is the distance between the two ends of the first connecting arm 121. There are multiple vertical distances between the first connecting arm 121 and the line connecting the two ends of the first connecting arm 121. The height is the maximum vertical distance between the first connecting arm 121 and the line connecting the two ends of the first connecting arm 121. The straight-line distance between the two ends of the first connecting arm 121 is the length L2 of the first connecting arm 121, and the maximum vertical distance between the first connecting arm 121 and the line connecting the two ends of the first connecting arm 121 is the height L1 of the first connecting arm 121. The ratio of the height L1 to the length L2 is in the range of 0.9 to 1.1. By designing the height L1 and length L2 of the first connecting arm 121, the first connecting arm 121 can have a higher structural rigidity, thereby preventing the first connecting arm 121 from being excessively bent or deformed under the action of the door gravity or other external forces, and maintaining the normal working state of the hinge. At the same time, the rotation range and rotation angle of the first connecting arm 121 can be limited to avoid collision with other structures of the vehicle during operation.

[0069] In one embodiment, the ratio of the length L2 to the height L1 is 1, the structural rigidity of the first connecting arm 121 is higher, and the first connecting arm 121 can provide more stable support for the vehicle door, ensuring the sinking rigidity of the vehicle door.

[0070] In some other embodiments, the ratio of the length L2 to the height L1 is 0.9, 1.05, 1.1, and so on.

[0071] In a possible implementation, the length L2 is in the range of 100 mm to 110 mm. Under this design, the hinge with the first connecting arm 121 not only has higher structural rigidity but is also more suitable for sports car-type vehicles.

[0072] In one possible implementation, see Figure 6 , Figure 7 and Figure 8As shown, the hinge 100 further includes a positioning structure 160, which includes a positioning pin 161 and a nut 162. A first positioning hole 1312 is provided on the second hinge leaf 130, and the first positioning hole 1312 is provided on the second mounting seat 131. The first positioning hole 1312 is located on the side of the second mounting seat 131 away from the first mounting seat 122. The positioning structure 160 is used to cooperate with the first positioning hole 1312 and the second positioning hole on the vehicle body (not shown in the figure) to connect the hinge and the vehicle body. The positioning pin 161 passes through the first positioning hole 1312 and the nut 162 to ensure the relative position of the positioning structure 160 and the hinge 100. At the same time, when the door is installed and disassembled, the positioning structure 160 can also be used as a fulcrum for the weight of the door, which can effectively save effort.

[0073] At least one scale line 1313 is arranged on the periphery of the edge of the first positioning hole 1312, and the positioning structure 160 is used to be fixed at different positions with the first positioning hole 1312 to cover different numbers of scale lines 1313. There is at least one scale line 1313. The at least one scale line 1313 can be arranged at equal intervals or at unequal intervals. The spacing between the scale lines 1313 can also be designed according to actual conditions. After the positioning nut 162 is threadedly connected with the positioning pin 161, the positioning nut 162 covers part of the scale lines 1313. If the position of the door needs to be adjusted during the door matching process, the threaded connection between the positioning nut 162 and the positioning pin 161 is released, and the position of the positioning pin 161 is adjusted along the direction of the scale lines 1313, so that the positioning nut 162 covers different scale lines 1313, which can achieve the purpose of visually and accurately adjusting the relative position of the positioning pin 161 and the hinge 100.

[0074] In a possible implementation, the hinge 100 includes an adjusting portion 171, and the adjusting portion 171 is used to cooperate with an external adjusting member to adjust the relative position of the second hinge leaf 130 and the vehicle body, and the second hinge leaf 130 moves relative to the adjusting portion 171. Fig.12 and Fig.13 As shown, the adjustment portion 171 can be located on the hinge mounting plate 170, and the second hinge 130 can move relative to the adjustment portion 171 so that the second hinge 130 is close to or away from the adjustment portion 171, thereby being able to accurately adjust the relative position of the second hinge 130 and the vehicle body so that the vehicle body and the hinge are accurately installed.

[0075] In one possible implementation, see Fig. 9As shown, the second hinge 130 includes a second connecting arm 132, the second connecting arm 132 is fixedly connected to the second mounting seat 131, the second connecting arm 132 is sleeved on the hinge shaft 110 and is fixedly connected to the hinge shaft 110, and the second connecting arm 132 is fixedly connected to the second mounting seat 131, for example, the second connecting arm 132 and the second mounting seat 131 can be riveted. A reinforcing structure 133 is provided at the connection between the second connecting arm 132 and the second mounting seat 131, and the reinforcing structure 133 can be in a triangular cone shape, which can ensure the rigidity, stability and strength of passive safety in the opening process of the hinge 100.

[0076] In one possible implementation, see Fig.10 As shown, the hinge shaft 110 is fixedly connected to the second mounting seat 131, and the hinge 100 has an inclination angle β, which is the angle between the projection of the axis of the hinge shaft 110 on the X=0 plane and the Z axis. The inclination angle β is in the range of 25° to 30°.

[0077] In one possible implementation, see Fig.11 As shown, the hinge 100 has a front-to-back tilt angle α, which is the angle between the projection of the axis of the hinge shaft 110 on the Y=0 plane and the Z axis. The angle of the front-to-back tilt angle α is in the range of 42° to 47°. The hinge shaft 110 adopts a large front-to-back tilt angle and an inner-outer tilt angle design to meet the butterfly-type composite opening and closing mode of the door.

[0078] The present application also provides a vehicle door, which includes any of the above-mentioned hinges 100. The vehicle door may be a special-shaped vehicle door (such as a butterfly door) or other types of vehicle doors.

The second hinge 130 of the hinge 100 is used to connect with the vehicle body. It can be understood that the connection between the door and the vehicle body and the hinge 100 is not limited to a certain method. For example, the second hinge 130 can be fixedly connected to the vehicle body by welding, and the second hinge 130 can be fixedly connected to the vehicle body by riveting, and the second hinge 130 can be fixedly connected to the vehicle body by bolts.

[0081] The vehicle door provided in the present application is connected to the vehicle body by a hinge 100. The hinge 100 is lightweight, making the door easier to open and close. In addition, the hinge 100 has good structural rigidity, can withstand long-term use of the butterfly door, and ensures sufficient door sinking rigidity during use.

[0082] In a possible implementation, the hinge 100 further includes a hinge mounting plate 170, and the hinge mounting plate 170 is fixedly connected to the second mounting seat 131. An adjusting portion 171 is provided on the hinge mounting plate 170, and the hinge 100 includes an adjusting member 163, and the adjusting member 163 is matched and connected with the adjusting portion 171, and one end of the adjusting member 163 abuts against the second hinge leaf 130, and the adjusting member 163 is used to match and connect with the adjusting portion 171 at different positions to allow the second hinge leaf 130 to rotate around the positioning structure 160.

[0083] See also Fig.12 and Fig.13 As shown, the adjusting member 163 may be a bolt, and the adjusting portion 171 may have a threaded hole matched with the bolt, the bolt is matched with the threaded hole, and one end of the bolt passes through the adjusting portion 171 and abuts against the second hinge 130. According to the actual situation of the door, one end of the bolt may move relative to the adjusting portion 171 along the axial direction of the bolt to ensure that the bolt and the adjusting portion 171 are matched and connected at different positions, so that the bolt can push the second hinge 130 to rotate around the positioning structure 160 along the axial direction of the bolt to adjust the position of the second hinge 130, which has a good labor-saving effect.
