[0056] In the embodiments of the present application, refer to Figures 1 to 10The present application provides a car, which includes: a body 200, a door 300 and a door hinge 100. The door hinge 100 rotatably connects the door 300 to the body 200. The door 300 changes its relative position with the body 200 through the door hinge 100, thereby realizing the opening and closing of the door 300.

[0057] The automobile may be not only a vehicle without a B-pillar and a double-door design, but may also be a vehicle with a B-pillar, but is not limited thereto.

[0058] The vehicle door 300 may be a front door or a rear door of the vehicle, and this application does not make any specific limitation thereto, and the vehicle door 300 may be set according to actual circumstances.

[0059] In one embodiment, a plurality of door hinges 100 are provided, and each group of door hinges 100 is used to realize the connection between the door 300 and the vehicle body 200 to ensure the reliability of the connection between the door 300 and the vehicle body 200 .

[0060] Specifically, the door hinge 100 has a first direction X, a second direction Z, and a third direction Y that intersect each other. Exemplarily, in the application, the door hinge 100 has a first direction X, a second direction Z, and a third direction Y that are perpendicular to each other. Here, "perpendicular" means that the angle formed by a straight line, a straight line and a plane, or a plane and a plane is 89° to 91°.

[0061] In order to solve the technical problem that the door hinges in the prior art cannot effectively support the door, and the design strength of the door hinges cannot meet the working conditions of the car without the B-pillar and the door design, specifically, refer to Figures 1 to 10 The door hinge 100 includes: a first mounting member 110, a pin shaft 120 and a second mounting member 130, the pin shaft 120 extends along the second direction Z, the first mounting member 110 is rotatably connected to the second mounting member 130 through the pin shaft 120, the first mounting member 110 is mounted on the vehicle body 200, and the first mounting member 110 is fixedly connected to the vehicle body 200, the second mounting member 130 is mounted on the vehicle door 300, and the second mounting member 130 is fixedly connected to the vehicle door 300.

[0062] The first mounting member 110 and the second mounting member 130 are both made of profiled steel, but not limited thereto, so as to improve the structural strength of the first mounting member 110 and the second mounting member 130 .

[0063] Specifically, refer to Figure 6 to Figure 7, the dimension of the first mounting member 110 in the first direction X is L1 mm, and the dimension of the first mounting member 110 in the second direction Z is L2 mm, satisfying: 0.7≤L2 / L1≤0.889. That is, the ratio of the dimension L2 mm of the first mounting member 110 in the second direction Z to the dimension L1 mm of the first mounting member 110 in the first direction X can be controlled within the range of 0.7 to 0.889. Exemplarily, L2 / L1 can be a range consisting of one of 0.7, 0.72, 0.74, 0.76, 0.78, 0.8, 0.82, 0.84, 0.88 or 0.889 or any two thereof. The above specific values ​​of L2 / L1 are given for example only, and any value within the range of 0.7 to 0.889 is within the protection scope of the present application.

[0064] The dimension L1 mm of the first mounting member 110 in the first direction X can be obtained by disassembling the door hinge 100 in an actual automobile, measuring the distance between two outer wall surfaces of the first mounting member 110 arranged opposite to each other in the first direction X for multiple times using a measuring tool, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0065] The dimension L2 mm of the first mounting member 110 in the second direction Z can be obtained by disassembling the door hinge 100 in an actual automobile, measuring the distance between two outer wall surfaces of the first mounting member 110 arranged opposite to each other in the second direction Z by a measuring tool for multiple times, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0066] It can be understood that when the value of L2 / L1 is less than 0.7, the overall structure of the first mounting component 110 is smaller and the overall structural strength is lower, and the connection between the vehicle body 200 and the door 300 cannot be effectively achieved; when the value of L2 / L1 is greater than 0.889, the overall structure of the first mounting component 110 is larger, occupying more space, affecting the structural size and strength of other components.

[0067] The present application controls the ratio of the dimension L2 mm of the first mounting member 110 in the second direction Z to the dimension L1 mm of the first mounting member 110 in the first direction X within the range of 0.7 to 0.889, so as to reasonably design the overall structural size of the first mounting member 110 and optimize the structural size of the first mounting member 110, thereby effectively improving the structural strength and rigidity of the first mounting member 110, thereby ensuring that the door hinge 100 can carry a heavier door 300, ensuring the overall structural stability of the door hinge 100 during use, and ensuring that there is no abnormality in the door 300 during use, so as to meet the door use conditions of a car without a B-pillar design.

[0068] In one embodiment, the dimension L1 mm of the first mounting member 110 in the first direction X also satisfies: 90 mm ≤ L1 ≤ 100 mm. That is, the dimension L1 mm of the first mounting member 110 in the first direction X can be controlled within the range of 90 mm to 100 mm. Exemplarily, L1 mm can be one of 90 mm, 91 mm, 92 mm, 93 mm, 94 mm, 95 mm, 96 mm, 97 mm, 98 mm, 99 mm or 100 mm, or a range consisting of any two of them. The above specific values ​​of L1 mm are given for example only, and any value within the range of 90 mm to 100 mm is within the protection scope of the present application.

[0069] The present application limits the dimension L1 mm of the first mounting member 110 in the first direction X to be within the range of 90 mm to 100 mm, so as to further reasonably design the overall structural size of the first mounting member 110, optimize the structural size of the first mounting member 110, and effectively improve the structural strength and rigidity of the first mounting member 110, so as to ensure that the door hinge 100 can bear a heavier door 300, and ensure the overall structural stability of the door hinge 100 during use.

[0070] The dimension L2 mm of the first mounting member 110 in the second direction Z also satisfies: 70 mm ≤ L2 ≤ 80 mm. That is, the dimension L2 mm of the first mounting member 110 in the second direction Z can be controlled within the range of 70 mm to 80 mm. Exemplarily, L2 mm can be one of 70 mm, 71 mm, 72 mm, 73 mm, 74 mm, 75 mm, 76 mm, 77 mm, 78 mm, 79 mm or 80 mm, or a range consisting of any two of them. The above specific values ​​of L2 mm are given for example only, and any value within the range of 70 mm to 80 mm is within the protection scope of the present application.

[0071] The present application limits the dimension L2 mm of the first mounting component 110 in the second direction Z to be controlled within the range of 70 mm to 80 mm, so as to further reasonably design the overall structural size of the first mounting component 110, optimize the structural size of the first mounting component 110, and effectively improve the structural strength and rigidity of the first mounting component 110, so as to ensure that the door hinge 100 can bear a heavier door 300, and ensure the overall structural stability of the door hinge 100 during use.

[0072] In order to improve the structural strength of the second mounting member 130, in one embodiment, referring to Figure 6 to Figure 7, the dimension of the second mounting member 130 in the third direction Y is L3 mm, and the dimension of the second mounting member 130 in the second direction Z is L4 mm, satisfying: 0.37≤L3 / L4≤0.43. That is, the ratio of the dimension L3 mm of the second mounting member 130 in the third direction Y to the dimension L4 mm of the second mounting member 130 in the second direction Z can be controlled within the range of 0.37 to 0.43. Exemplarily, L3 / L4 can be a range consisting of one of 0.37, 0.375, 0.38, 0.385, 0.39, 0.395, 0.40, 0.405, 0.41, 0.415, 0.42, 0.425 or 0.43 or any two thereof. The above specific values ​​of L3 / L4 are given for example only, and any value within the range of 0.37 to 0.43 is within the protection scope of the present application.

[0073] The dimension L3 mm of the second mounting member 130 in the third direction Y can be obtained by disassembling the door hinge 100 in an actual automobile, measuring the distance between two outer wall surfaces of the second mounting member 130 that are oppositely arranged in the third direction Y by a measuring tool for multiple times, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0074] The dimension L4 mm of the second mounting member 130 in the second direction Z can be obtained by disassembling the door hinge 100 in an actual automobile, measuring the distance between two outer wall surfaces of the second mounting member 130 arranged opposite to each other in the second direction Z by using a measuring tool for multiple times, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0075] It can be understood that when the value of L3 / L4 is less than 0.37, the overall structure of the second mounting component 130 is smaller and the overall structural strength is lower, and the connection between the vehicle body 200 and the door 300 cannot be effectively achieved; when the value of L3 / L4 is greater than 0.43, the overall structure of the second mounting component 130 is larger, occupying more space, affecting the structural size and strength of other components.

[0076] The present application reasonably designs the overall structural size of the second mounting member 130 by setting the ratio of the dimension L3 mm of the second mounting member 130 in the third direction Y to the dimension L4 mm of the second mounting member 130 in the second direction Z in the range of 0.37 to 0.43, optimizes the structural size of the second mounting member 130, effectively improves the structural strength and rigidity of the second mounting member 130, further ensures that the door hinge 100 can carry a heavier door 300, ensures the overall structural stability of the door hinge 100 during use, and ensures that there is no abnormality in the door 300 during use, so as to meet the door use conditions of a car without a B-pillar design.

[0077] At the same time, the present application further ensures the overall structural stability of the door hinge 100 during use by simultaneously optimizing the structural size of the first mounting member 110 and the second mounting member 130, and ensures that there are no abnormalities in the door 300 during use, so as to meet the door usage conditions of a car without a B-pillar design.

[0078] In one embodiment, the dimension L3 mm of the second mounting member 130 in the third direction Y also satisfies: 55 mm ≤ L3 ≤ 65 mm. That is, the dimension L3 mm of the second mounting member 130 in the third direction Y can be controlled within the range of 55 mm to 65 mm. Exemplarily, L3 mm can be one of 55 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, 61 mm, 62 mm, 63 mm, 64 mm or 65 mm, or a range consisting of any two of them. The above specific values ​​of L3 mm are given for example only, and any value within the range of 55 mm to 65 mm is within the protection scope of the present application.

[0079] The present application limits the dimension L3 mm of the second mounting component 130 in the third direction Y to within the range of 55 mm to 65 mm, so as to further reasonably design the overall structural size of the second mounting component 130, optimize the structural size of the second mounting component 130, effectively improve the structural strength and rigidity of the second mounting component 130, further ensure that the door hinge 100 can bear a heavier door 300, and ensure the overall structural stability of the door hinge 100 during use.

[0080] The dimension L4 mm of the second mounting member 130 in the second direction Z also satisfies: 150 mm ≤ L4 ≤ 160 mm. That is, the dimension L4 mm of the second mounting member 130 in the second direction Z can be controlled within the range of 150 mm to 160 mm. Exemplarily, L4 mm can be one of 150 mm, 151 mm, 152 mm, 153 mm, 154 mm, 155 mm, 156 mm, 157 mm, 158 mm, 159 mm or 160 mm, or a range consisting of any two of them. The above specific values ​​of L4 mm are given for example only, and any value within the range of 150 mm to 160 mm is within the protection scope of the present application.

[0081] The present application limits the dimension L4 mm of the second mounting component 130 in the second direction Z to within the range of 150 mm to 160 mm, so as to further reasonably design the overall structural size of the second mounting component 130, optimize the structural size of the second mounting component 130, effectively improve the structural strength and rigidity of the second mounting component 130, further ensure that the door hinge 100 can bear a heavier door 300, and ensure the overall structural stability of the door hinge 100 during use.

[0082] In one embodiment, referring to Figures 1 to 3 The first mounting member 110 includes: a first mounting portion 111 and a first adapter portion 113 . The first mounting portion 111 is mounted on the vehicle body 200 . The first adapter portion 113 is connected to a side of the first mounting portion 111 close to the second mounting member 130 .

[0083] The first mounting portion 111 and the first adapter portion 113 are integrally die-cast.

[0084] The second mounting member 130 includes: a second mounting portion 131 and a second adapter portion 132 . The second mounting portion 131 is mounted on the vehicle door 300 . The second adapter portion 132 is connected to a side of the second mounting portion 131 close to the first mounting member 110 . The second adapter portion 132 is rotatably connected to the first adapter portion 113 via the pin shaft 120 .

[0085] Among them, the second mounting portion 131 and the second adapter portion 132 can be integrally formed, that is, the second mounting portion 131 and the second adapter portion 132 are an integral structure; the second mounting portion 131 and the second adapter portion 132 can also be separately provided, and the two are fixedly connected. For example, the second adapter portion 132 is fixedly connected to the second mounting portion 131 by welding or other processes. This is not specifically limited in this application and can be specifically set according to actual circumstances. For example, in this application, the second mounting portion 131 and the second adapter portion 132 are integrally die-cast.

[0086] In order to further improve the structural strength of the first mounting member 110, in one embodiment, referring to Figure 6 to Figure 7 The first mounting member 110 further includes: a bending portion 112, which is disposed between the first mounting portion 111 and the first adapter portion 113, and the first mounting portion 111 is connected to the first adapter portion 113 through the bending portion 112 to achieve connection between the first mounting portion 111 and the first adapter portion 113.

[0087] The first mounting portion 111 , the bending portion 112 and the first transition portion 113 are integrally die-cast.

[0088] Specifically, the thickness of the first mounting portion 111 is H1 mm, and the thickness of the bending portion 112 is H2 mm, which satisfies: H1<H2. That is, the thickness H2 mm of the bending portion 112 is greater than the thickness H1 mm of the first mounting portion 111, so as to further reasonably design the overall structural size of the first mounting member 110, so as to improve the structural strength of the bending portion 112 of the first mounting member 110, thereby improving the overall structural strength and rigidity of the first mounting member 110, ensuring that the bending portion 112 can effectively support the vehicle door 300 during use, so that the vehicle door 300 can be used without abnormality, so as to meet the vehicle door use conditions of the vehicle without a B-pillar design.

[0089] The thickness H1 mm of the first mounting portion 111 can be obtained by disassembling the door hinge 100 in an actual car, measuring the thickness of different positions of the first mounting portion 111 in the first mounting member 110 multiple times using a measuring tool, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0090] The thickness H2 mm of the bending portion 112 can be obtained by disassembling the door hinge 100 in an actual car, measuring the thickness of the bending portion 112 at different positions of the first mounting member 110 with a measuring tool for multiple times, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0091] Specifically, the thickness of the bending portion 112 can be uniform or non-uniform. When it is a structure with uniform thickness, the thickness ratio between the bending portion 112 and the first mounting portion 111 is fixed. If the bending portion 112 is not a structure with uniform thickness, the thickness ratio is a range value rather than a single point data.

[0092] Usually, in order to facilitate processing and forming, the thickness of the bending portion 112 at different positions is consistent. Even if it is inconsistent, it is based on the existence of a small thickness difference due to processing.

[0093] Specifically, the thickness H1 mm of the first mounting portion 111 and the thickness H2 mm of the bending portion 112 also satisfy: 1.38≤H2 / H1≤3.5. That is, the ratio of the thickness H2 mm of the bending portion 112 to the thickness H1 mm of the first mounting portion 111 can be controlled within the range of 1.38 to 3.5. Exemplarily, when the thickness ratio between the bending portion 112 and the first mounting portion 111 is fixed, H2 / H1 can be 1.38, 1.4, 1.6, 1.8, 2, 2.2, 2.4, 2.6, 2.8, 3, 3.2, 3.4 or 3.5. It should be noted that when the thickness ratio between the bending portion 112 and the first mounting portion 111 is a range value, any value of H2 / H1 within the range of 1.38 to 1.8, 1.7 to 2.5, 2.5 to 3 or 2.9 to 3.5 is within the protection scope of the present application. It is worth noting that the specific value of H2 / H1 is given for example only, and any value within the range of 1.38 to 3.5 is within the protection scope of the present application.

[0094] The present application limits the ratio of the thickness H2 mm of the bending portion 112 to the thickness H1 mm of the first mounting portion 111 within the range of 1.38 to 3.5, so as to further reasonably design the overall structural size of the first mounting member 110, improve the structural strength of the bending portion 112 of the first mounting member 110, and further improve the overall structural strength and rigidity of the first mounting member 110, thereby ensuring that the bending portion 112 can effectively support the vehicle door 300 during use, so that the vehicle door 300 can be used without abnormalities, thereby meeting the door usage conditions of a car without a B-pillar design.

[0095] In one embodiment, the thickness H1 mm of the first mounting portion 111 also satisfies: 8 mm ≤ H1 ≤ 13 mm. That is, the thickness H1 mm of the first mounting portion 111 can be controlled within the range of 8 mm to 13 mm. Exemplarily, H1 mm can be 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm or 13 mm, or a range consisting of any two of them. The above specific values ​​of L4 mm are given for example only, and any value within the range of 8 mm to 13 mm is within the protection scope of this application. The present application limits the thickness H1 mm of the first mounting portion 111 to be within the range of 8 mm to 13 mm, so as to further reasonably design the overall structural size of the first mounting member 110, thereby improving the structural strength of the first mounting portion 111 of the first mounting member 110, thereby effectively improving the structural strength and rigidity of the first mounting member 110, ensuring that the door hinge 100 can bear a heavier door 300, and ensuring the overall structural stability of the door hinge 100 during use.

[0096] The thickness H2 mm of the bending portion 112 also satisfies: 18 mm ≤ H2 ≤ 28 mm. That is, the thickness H2 mm of the bending portion 112 can be controlled within the range of 18 mm to 28 mm. Exemplarily, when the thickness of the bending portion 112 is fixed, H2 mm can be 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm or 28 mm. It should be noted that when the thickness of the bending portion 112 is not uniform, any value of H2 mm within the range of 18 to 20 mm, 20 to 25 mm or 25 to 28 mm is within the protection scope of the present application. It is worth noting that the specific numerical value of H2 mm is only given as an example, and any value within the range of 18 mm to 28 mm is within the protection scope of the present application.

[0097] The present application limits the thickness H2 mm of the bent portion 112 to be within the range of 18 mm to 28 mm, so as to further improve the structural strength of the bent portion 112 of the first mounting member 110, thereby improving the overall structural strength and rigidity of the first mounting member 110, ensuring that the bent portion 112 can effectively support the vehicle door 300 during use, so that the vehicle door 300 can be used without abnormalities, thereby meeting the door usage conditions of a vehicle without a B-pillar design.

[0098] In one embodiment, referring to Figures 1 to 3 The first mounting portion 111 is provided with a plurality of first mounting holes 1111, and each of the first mounting holes 1111 is respectively provided on two sides of the first mounting portion 111 that are arranged opposite to each other in the second direction Z. Exemplarily, each of the first mounting holes 1111 is respectively provided in the corner area of ​​the first mounting portion 111. The present application provides a plurality of first mounting holes 1111 on the first mounting portion 111, so as to utilize the plurality of first mounting holes 1111 to realize the installation between the first mounting member 110 and the vehicle body 200, thereby improving the mounting structural strength and modality of the first mounting member 110, ensuring that the door hinge 100 can effectively support the vehicle door 300 during use, so that the vehicle door 300 can be used without abnormality, so as to meet the door use conditions of the vehicle without a B-pillar design.

[0099] Illustratively, in the present application, four first mounting holes 1111 are opened on the first mounting portion 111 , and the four first mounting holes 1111 are respectively arranged at four corner areas of the first mounting portion 111 .

[0101] The first fastener 140 may be a bolt, but is not limited thereto.

[0102] In order to further improve the structural strength of the second mounting member 130, in one embodiment, referring to Figure 7 , the thickness of the second mounting portion 131 is H3 mm, satisfying: 7mm≤H3≤15mm. That is, the thickness H3 mm of the second mounting portion 131 can be controlled within the range of 7mm to 15mm. Exemplarily, H3 mm can be a range consisting of one of 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm or 15mm, or any two of them. The above specific values ​​of H3 mm are given for example only, and any value within the range of 8mm to 13mm is within the protection scope of this application. The present application limits the thickness H3 mm of the second mounting portion 131 to be within the range of 7 mm to 15 mm, so as to further reasonably design the overall structural size of the second mounting member 130, thereby improving the structural strength of the second mounting portion 131 in the second mounting member 130, effectively improving the structural strength and rigidity of the second mounting member 130, and ensuring the overall structural stability of the door hinge 100.

[0103] The thickness H3 mm of the second mounting portion 131 can be obtained by disassembling the door hinge 100 in an actual car, measuring the thickness of different positions of the second mounting portion 131 in the second mounting member 130 multiple times with a measuring tool, and calculating the average value. The measuring tool can be any one of a ruler, a vernier caliper, or other dimension measuring instruments, but is not limited thereto.

[0104] In one embodiment, referring to Figures 1 to 3 , a plurality of second mounting holes 1311 are provided on the second mounting portion 131, and each first mounting hole 1111 is respectively provided on two sides of the first mounting portion 111 that are arranged opposite to each other in the second direction Z. Exemplarily, each second mounting hole 1311 is respectively provided in the corner area of ​​the second mounting portion 131. In the present application, a plurality of second mounting holes 1311 are provided on the second mounting portion 131, so as to realize the installation between the second mounting member 130 and the vehicle door 300 by utilizing the plurality of second mounting holes 1311, thereby improving the mounting structural strength and modality of the second mounting member 130, ensuring that the door hinge 100 can effectively support the vehicle door 300 during use, so that the vehicle door 300 can be used without abnormality, so as to meet the vehicle door use conditions of the vehicle without a B-pillar design.

[0105] Exemplarily, in the present application, four second mounting holes 1311 are provided on the second mounting portion 131, and the four second mounting holes 1311 are respectively provided at four corner areas of the second mounting portion 131. Specifically, three second mounting holes 1311 are provided at the upper portion of the second mounting portion 131, and one second mounting hole 1311 is provided at the lower portion of the second mounting portion 131.

[0106] In one embodiment, the door hinge 100 further includes: a plurality of second fasteners 150 , each second fastener 150 is respectively passed through a corresponding second mounting hole 1311 , and the second fastener 150 is fixedly connected to the door 300 to achieve installation of the second mounting member 130 on the door 300 .

[0107] The second fastener 150 may be a bolt, but is not limited thereto.

[0108] In order to achieve the door opening limit of the vehicle door 300, in one embodiment, referring to Figures 1 to 8 The first mounting member 110 further includes: a first limiting portion 114 , and the first limiting portion 114 is disposed on a side of the first transition portion 113 in the second direction Z close to the second transition portion 132 .

[0109] The second mounting member 130 further includes a second limiting portion 133 , which is disposed on a side of the second adapter portion 132 away from the second mounting portion 131 . The second limiting portion 133 can selectively abut against the first limiting portion 114 to achieve the door opening limit of the vehicle door 300 .

[0110] Among them, the first limiter 114 and the first adapter 113 can be integrally formed, that is, the first limiter 114 and the first adapter 113 are an integral structure; the first limiter 114 and the first adapter 113 can also be separately provided, and the two are fixedly connected. For example, the first limiter 114 is fixedly connected to the first adapter 113 by welding or other processes. This is not specifically limited in this application and can be specifically set according to actual circumstances. For example, in this application, the first limiter 114 and the first adapter 113 are integrally die-cast.

[0111] The second position limiting portion 133 and the second transition portion 132 can be integrally formed, that is, the second position limiting portion 133 and the second transition portion 132 are an integral structure; the second position limiting portion 133 and the second transition portion 132 can also be separately provided, and the two are fixedly connected. For example, the second position limiting portion 133 is fixedly connected to the second transition portion 132 by welding or other processes. This is not specifically limited in this application, and can be specifically set according to actual circumstances. For example, in this application, the second position limiting portion 133 and the second transition portion 132 are integrally die-cast.

[0112] It can be understood that the door 300 of the automobile has two states: open and closed. Figure 7 When the door 300 is in the open state, the second limiting portion 133 does not contact the first limiting portion 114. When the door 300 is opened, the second mounting member 130 is synchronously driven to rotate around the central axis of the pin shaft 120. Figure 8 As shown, when the vehicle door 300 is opened to a certain angle, the second limiting portion 133 abuts against the first limiting portion 114 to limit the second mounting member 130 and further limit the vehicle door 300 to prevent damage to components due to excessive door opening angle.

[0113] In one embodiment, referring to Figures 1 to 3 A first through hole 1131 is formed on the first adapter portion 113, and a second through hole 1321 is formed on the second adapter portion 132; the pin 120 is passed through the first through hole 1131 and the second through hole 1321 to rotatably connect the first mounting member 110 and the second mounting member 130. The overall structure is simple and easy to process and assemble.

[0114] In one embodiment, referring to Figures 4 to 5 The first adapter portion 113 is provided with a third through hole 1132. The door hinge 100 further includes a third fastener 160, which is passed through the third through hole 1132 to be fixedly connected with the pin shaft 120, so as to fix the pin shaft 120.

[0115] The third fastener 160 may be a bolt, but is not limited thereto.

[0116] In one embodiment, referring to Figures 4 to 5 A avoidance hole 1312 is opened on the second mounting portion 131, and part of the third fastener 160 is located in the avoidance hole 1312 to avoid the third fastener 160, so that the overall structure of the door hinge 100 is compact and occupies a small space.

[0117] It should be understood that the third fastener 160 is not limited to cooperating with the first mounting member 110 to achieve fixation of the pin shaft 120. In the present application, the third fastener 160 can also be passed through the second adapter portion 132 of the second mounting member 130 and fixedly connected to the pin shaft 120 to achieve fixation of the pin shaft 120, which should also be regarded as an embodiment of the present application.

[0118] In summary, the present application optimizes the design of the structural dimensions of the first mounting member 110 and the second mounting member 130 in the door hinge 100 to improve the structural strength and rigidity of the first mounting member 110 and the second mounting member 130, thereby ensuring the overall structural strength and rigidity of the door hinge 100, ensuring the overall structural stability of the door hinge 100 during use, and ensuring that there are no abnormalities in the door 300 during use, so as to meet the door usage conditions of a car without a B-pillar design.
