Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a door hinge and an automobile. Background Technology

[0002] Car doors are connected to the vehicle body to open and close, and door hinges are located between the vehicle body and the door to connect the two to each other. Therefore, the door is rotatably connected to the vehicle body to open and close.

[0003] In cars with a pillarless design, the elimination of the traditional B-pillar necessitates the addition of components to the door assembly to enhance its strength in order to meet overall vehicle performance requirements. This results in an increase in the weight of the door assembly, making it difficult for existing door hinges to effectively support the door. Consequently, the design strength of the door hinges cannot meet the operating conditions of cars with pillarless door designs. Utility Model Content

[0052] To make the objectives, technical solutions, and beneficial effects of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0053] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In the embodiments of this application, reference is made to Figures 1 to 10This application provides an automobile, 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 to the body 200 through the door hinge 100, thereby realizing the opening and closing of the door 300.

[0057] Among them, the car can be not only a vehicle with a B-pillar-less, double-door design, but also a vehicle with a B-pillar, but is not limited to this.

[0058] The door 300 can be the front door or the rear door of the car. This application does not make specific limitations and can be set according to the actual situation.

[0059] In one embodiment, multiple sets of door hinges 100 are provided, and each set of door hinges 100 is used to realize the connection between the door 300 and the body 200, so as to ensure the reliability of the connection between the door 300 and the 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 in pairs. For example, 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 in pairs. Here, "perpendicular" refers to a state where the angle formed by a straight line and a straight line, a straight line and a surface, or a surface and a surface is 89° to 91°.

[0061] To address the technical issues of existing door hinges failing to effectively support the door and their design strength being insufficient for the operating conditions of vehicles with doors that open without a B-pillar, specifically, refer to... Figures 1 to 10 The door hinge 100 includes: a first mounting member 110, a pin 120 and a second mounting member 130. The pin 120 extends along the second direction Z. The first mounting member 110 is rotatably connected to the second mounting member 130 through the pin 120. The first mounting member 110 is mounted on the vehicle body 200 and is fixedly connected to the vehicle body 200. The second mounting member 130 is mounted on the door 300 and is fixedly connected to the door 300.

[0062] The first mounting component 110 and the second mounting component 130 are both made of structural steel, but are not limited to this, in order to improve the structural strength of the first mounting component 110 and the second mounting component 130.

[0063] Specifically, refer to Figures 6 to 7The first mounting member 110 has a dimension of L1 mm in the first direction X and a dimension of L2 mm in the second direction Z, 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. For example, L2 / L1 can be one or any combination of 0.7, 0.72, 0.74, 0.76, 0.78, 0.8, 0.82, 0.84, 0.88, or 0.889. The specific values ​​of L2 / L1 given above are merely illustrative; any value within the range of 0.7 to 0.889 is within the scope of protection of this application.

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

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

[0066] Understandably, when the L2 / L1 ratio is less than 0.7, the overall structure of the first mounting component 110 is small and the overall structural strength is low, making it impossible to effectively connect the body 200 and the door 300. When the L2 / L1 ratio is greater than 0.889, the overall structure of the first mounting component 110 is large, which takes up a lot of space and affects the size and strength of other components.

[0067] This application controls the ratio of the first mounting member 110's dimension L2 mm in the second direction Z to its dimension L1 mm in the first direction X within the range of 0.7 to 0.889, thereby rationally designing the overall structural size of the first mounting member 110 and optimizing its structural size. This effectively improves the structural strength and rigidity of the first mounting member 110, ensuring that the door hinge 100 can bear the weight of the door 300, guaranteeing the overall structural stability of the door hinge 100 during use, and ensuring that the door 300 is free from abnormalities during use, thus meeting the door usage conditions of cars without B-pillar designs.

[0068] In one embodiment, the dimension L1 mm of the first mounting member 110 in the first direction X further satisfies: 90mm ≤ L1 ≤ 100mm. That is, the dimension L1 mm of the first mounting member 110 in the first direction X can be controlled within the range of 90mm to 100mm. For example, L1 mm can be one or any combination of 90mm, 91mm, 92mm, 93mm, 94mm, 95mm, 96mm, 97mm, 98mm, 99mm, or 100mm. The specific values ​​of L1 mm mentioned above are only given as examples, and any value within the range of 90mm to 100mm is within the protection scope of this application.

[0069] This application limits the dimension L1 mm of the first mounting member 110 in the first direction X to within the range of 90 mm to 100 mm, so as to further rationally design the overall structural size of the first mounting member 110, optimize the structural size of the first mounting member 110, effectively improve the structural strength and rigidity of the first mounting member 110, so as to ensure that the door hinge 100 can bear the weight of the 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. For example, L2 mm can be one or any combination of 70 mm, 71 mm, 72 mm, 73 mm, 74 mm, 75 mm, 76 mm, 77 mm, 78 mm, 79 mm, or 80 mm. The specific values ​​of L2 mm given above are only illustrative examples, and any value within the range of 70 mm to 80 mm is within the protection scope of this application.

[0071] This application limits the dimension L2 mm of the first mounting member 110 in the second direction Z to within the range of 70 mm to 80 mm, thereby further optimizing the overall structural size of the first mounting member 110 and improving its structural strength and rigidity. This ensures that the door hinge 100 can support the heavier door 300 and guarantees the overall structural stability of the door hinge 100 during use.

[0072] To enhance the structural strength of the second mounting member 130, in one embodiment, referring to... Figures 6 to 7The second mounting member 130 has a dimension of L3 mm in the third direction Y and a dimension of L4 mm in the second direction Z, 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. For example, L3 / L4 can be a range consisting of one or any two of the following: 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. The specific values ​​of L3 / L4 given above are merely illustrative; any value within the range of 0.37 to 0.43 is within the scope of protection of this application.

[0073] The dimension L3 mm of the second mounting component 130 in the third direction Y can be obtained by disassembling the actual car door hinge 100 and measuring the distance between the two opposite outer wall surfaces of the second mounting component 130 in the third direction Y multiple times using a measuring tool, and then calculating the average value. The measuring tool can be any one of a ruler, vernier caliper, or other dimensional measuring instruments, but is not limited to this.

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

[0075] Understandably, when the L3 / L4 ratio is less than 0.37, the overall structure of the second mounting component 130 is small and its overall structural strength is low, making it impossible to effectively connect the body 200 and the door 300. When the L3 / L4 ratio is greater than 0.43, the overall structure of the second mounting component 130 is large, which takes up a lot of space and affects the size and strength of other components.

[0076] This application optimizes the overall structural size of the second mounting member 130 by setting the ratio of its dimension L3 mm in the third direction Y to its dimension L4 mm in the second direction Z within the range of 0.37 to 0.43. This effectively improves the structural strength and rigidity of the second mounting member 130, further ensuring that the door hinge 100 can support the heavier door 300, guaranteeing the overall structural stability of the door hinge 100 during use, and ensuring that the door 300 operates without abnormalities during use, thus meeting the operating conditions of doors in cars without B-pillar designs.

[0077] Meanwhile, by simultaneously optimizing the structural size of the first mounting component 110 and the second mounting component 130, this application further ensures the overall structural stability of the door hinge 100 during use and ensures that the door 300 is free from abnormalities during use, so as to meet the door usage conditions of cars without B-pillars.

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

[0079] This application limits the dimension L3 mm of the second mounting member 130 in the third direction Y to within the range of 55 mm to 65 mm, so as to further rationally design the overall structural size of the second mounting member 130 and optimize the structural size of the second mounting member 130. This effectively improves the structural strength and rigidity of the second mounting member 130, further ensuring that the door hinge 100 can bear the weight of the door 300, and ensuring 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. For example, L4 mm can be one or any combination of 150 mm, 151 mm, 152 mm, 153 mm, 154 mm, 155 mm, 156 mm, 157 mm, 158 mm, 159 mm, or 160 mm. The specific values ​​of L4 mm given above are only illustrative examples, and any value within the range of 150 mm to 160 mm is within the protection scope of this application.

[0081] This application limits the dimension L4 mm of the second mounting member 130 in the second direction Z to within the range of 150 mm to 160 mm, so as to further rationally design the overall structural size of the second mounting member 130 and optimize the structural size of the second mounting member 130. This effectively improves the structural strength and rigidity of the second mounting member 130, further ensuring that the door hinge 100 can bear the weight of the door 300, and ensuring the overall structural stability of the door hinge 100 during use.

[0082] In one embodiment, reference is made to Figures 1 to 3 The first mounting component 110 includes a first mounting part 111 and a first adapter part 113. The first mounting part 111 is mounted on the vehicle body 200, and the first adapter part 113 is connected to the side of the first mounting part 111 near the second mounting component 130.

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

[0084] The second mounting component 130 includes a second mounting part 131 and a second adapter part 132. The second mounting part 131 is mounted on the door 300, and the second adapter part 132 is connected to the side of the second mounting part 131 near the first mounting component 110. The second adapter part 132 is rotatably connected to the first adapter part 113 via a pin 120.

[0085] The second mounting portion 131 and the second adapter portion 132 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the second mounting portion 131 and the second adapter portion 132 can be separately configured and fixedly connected. For example, the second adapter portion 132 is fixedly connected to the second mounting portion 131 via welding or other processes. This application does not impose specific limitations and can be configured 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] To further enhance the structural strength of the first mounting component 110, in one embodiment, referring to... Figures 6 to 7 The first mounting component 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 realize the connection between the first mounting portion 111 and the first adapter portion 113.

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

[0088] Specifically, the thickness of the first mounting portion 111 is H1 mm, and the thickness of the bent portion 112 is H2 mm, satisfying: H1 < H2. That is, the thickness H2 mm of the bent portion 112 is greater than the thickness H1 mm of the first mounting portion 111. This allows for a more rational design of the overall structural size of the first mounting component 110, thereby improving the structural strength of the bent portion 112 of the first mounting component 110. This, in turn, enhances the overall structural strength and rigidity of the first mounting component 110, ensuring that the bent portion 112 can effectively support the door 300 during use, thus ensuring that the door 300 operates without abnormalities and meeting the operating conditions of doors in cars without B-pillar designs.

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

[0090] The thickness H2 mm of the bent portion 112 can be obtained by disassembling the actual car door hinge 100 and measuring the thickness of the bent portion 112 at different locations in the first mounting part 110 multiple times using a measuring tool, and then calculating the average value. The measuring tool can be any one of a ruler, vernier caliper, or other dimensional measuring instruments, but is not limited to these.

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

[0092] Typically, for ease of processing and forming, the thickness of the bent portion 112 is consistent at different locations, or if it is inconsistent, it is only due to the existence of small thickness differences in processing.

[0093] Specifically, the thickness H1 mm of the first mounting portion 111 and the thickness H2 mm of the bent portion 112 also satisfy the following condition: 1.38 ≤ H2 / H1 ≤ 3.5. That is, the ratio of the thickness H2 mm of the bent 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. For example, when the thickness ratio between the bent 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 bent 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 this application. It is worth noting that the specific values ​​of H2 / H1 are given only as examples, and any value within the range of 1.38 to 3.5 is within the protection scope of this application.

[0094] This 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 to within the range of 1.38 to 3.5, thereby further optimizing the overall structural size of the first mounting member 110, improving the structural strength of the bending portion 112 of the first mounting member 110, and thus enhancing the overall structural strength and rigidity of the first mounting member 110. This ensures that the bending portion 112 can effectively support the door 300 during use, making the door 300 work without abnormalities, and meeting the door usage conditions of cars without B-pillar designs.

[0095] In one embodiment, the thickness H1 mm of the first mounting portion 111 further 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. For example, H1 mm can be one or any combination of 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. The specific values ​​of L4 mm mentioned above are only given as examples, and any value within the range of 8 mm to 13 mm is within the protection scope of this application. This application limits the thickness H1 mm of the first mounting part 111 to within the range of 8 mm to 13 mm to further optimize the overall structural size of the first mounting member 110, thereby improving the structural strength of the first mounting part 111 of the first mounting member 110. This effectively enhances the structural strength and rigidity of the first mounting member 110, ensuring that the door hinge 100 can support the heavier door 300 and guaranteeing the overall structural stability of the door hinge 100 during use.

[0096] The thickness H2 mm of the bent portion 112 also satisfies: 18 mm ≤ H2 ≤ 28 mm. That is, the thickness H2 mm of the bent portion 112 can be controlled within the range of 18 mm to 28 mm. For example, when the thickness of the bent 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 bent portion 112 is not uniform, any value of H2 mm within the range of 18–20 mm, 20–25 mm, or 25–28 mm is within the protection scope of this application. It is worth noting that the specific 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 this application.

[0097] This application limits the thickness H2 mm of the bending portion 112 to within the range of 18 mm to 28 mm to further enhance 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. This ensures that the bending portion 112 can effectively support the door 300 during use, so that the door 300 can be used without abnormalities, thus meeting the door usage conditions of cars without B-pillar designs.

[0098] In one embodiment, reference is made to Figures 1 to 3 The first mounting portion 111 has a plurality of first mounting holes 1111, each first mounting hole 1111 being respectively located on both sides of the first mounting portion 111 in the second direction Z. For example, each first mounting hole 1111 is respectively located in the corner area of ​​the first mounting portion 111. This application improves the strength and modal characteristics of the mounting structure of the first mounting component 110 by providing a plurality of first mounting holes 1111 on the first mounting portion 111, thereby ensuring that the door hinge 100 can be effectively supported during use, so that the door 300 can be used without abnormalities, thus meeting the door usage conditions of cars without B-pillar design.

[0099] For example, in this application, the first mounting part 111 is provided with four first mounting holes 1111, and the four first mounting holes 1111 are respectively disposed in the four corner areas of the first mounting part 111.

[0100] In one embodiment, the door hinge 100 further includes a plurality of first fasteners 140, each of the first fasteners 140 being respectively disposed in a corresponding first mounting hole 1111, and the first fasteners 140 being fixedly connected to the vehicle body 200, so as to realize the installation of the first mounting member 110 on the vehicle body 200.

[0101] The first fastener 140 can be a bolt, but is not limited to this.

[0102] To further enhance the structural strength of the second mounting component 130, in one embodiment, referring to... Figure 7 The thickness of the second mounting portion 131 is H3 mm, satisfying the condition: 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. For example, H3 mm can be any one or any combination 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. The specific values ​​of H3 mm given above are merely illustrative; any value within the range of 8mm to 13mm is within the scope of protection of this application. This application limits the thickness H3 mm of the second mounting part 131 to the range of 7 mm to 15 mm to further optimize the overall structural size of the second mounting member 130, thereby improving the structural strength of the second mounting part 131 in the second mounting member 130, effectively enhancing 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 part 131 can be obtained by disassembling the actual car door hinge 100, measuring the thickness of the second mounting part 131 at different positions in the second mounting component 130 multiple times using a measuring tool, and calculating the average value. The measuring tool can be any one of a ruler, vernier caliper, or other dimensional measuring instruments, but is not limited to these.

[0104] In one embodiment, reference is made to Figures 1 to 3 The second mounting portion 131 has a plurality of second mounting holes 1311, and each first mounting hole 1111 is respectively located on both sides of the first mounting portion 111 in the second direction Z. For example, each second mounting hole 1311 is located in the corner area of ​​the second mounting portion 131. By providing a plurality of second mounting holes 1311 on the second mounting portion 131, this application utilizes the plurality of second mounting holes 1311 to realize the installation between the second mounting member 130 and the door 300, thereby improving the structural strength and modal characteristics of the second mounting member 130, ensuring that the door hinge 100 can effectively support the door 300 during use, so that the door 300 can be used without abnormalities, thus meeting the door usage conditions of cars without B-pillar designs.

[0105] For example, in this application, the second mounting part 131 has four second mounting holes 1311, which are respectively located in the four corner areas of the second mounting part 131. Specifically, three second mounting holes 1311 are located in the upper part of the second mounting part 131, and one second mounting hole 1311 is located in the lower part of the second mounting part 131.

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

[0107] The second fastener 150 can be a bolt, but is not limited to this.

[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 component 110 further includes a first limiting part 114, which is disposed on the side of the first adapter 113 in the second direction Z near the second adapter 132.

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

[0110] The first limiting part 114 and the first transition part 113 can be integrally formed, that is, the first limiting part 114 and the first transition part 113 are a one-piece structure; the first limiting part 114 and the first transition part 113 can also be separately provided, and the two are fixedly connected. For example, the first limiting part 114 is fixedly connected to the first transition part 113 by welding or other processes. This application does not impose specific limitations, and can be specifically set according to actual circumstances. For example, in this application, the first limiting part 114 and the first transition part 113 are integrally die-cast.

[0111] The second limiting part 133 and the second transition part 132 can be integrally formed, that is, the second limiting part 133 and the second transition part 132 are a one-piece structure; the second limiting part 133 and the second transition part 132 can also be separately provided, and the two are fixedly connected. For example, the second limiting part 133 is fixedly connected to the second transition part 132 by welding or other processes. This application does not impose specific limitations, and the specific configuration can be determined according to the actual situation. For example, in this application, the second limiting part 133 and the second transition part 132 are integrally die-cast.

[0112] Understandably, car doors 300 have two states: open and closed. (Refer to...) Figure 7 When the door 300 is in the open position, the second limiting part 133 is not in contact with the first limiting part 114. When the door 300 is opened, it synchronously drives the second mounting part 130 to rotate around the central axis of the pin 120. Figure 8 As shown, when the door 300 is opened to a certain angle, the second limiting part 133 abuts against the first limiting part 114 to limit the second mounting part 130, thereby limiting the door 300 and preventing damage to the parts caused by the door opening angle being too large.

[0113] In one embodiment, reference is made to Figures 1 to 3 The first adapter 113 has a first through hole 1131 and the second adapter 132 has a second through hole 1321. The pin 120 passes through the first through hole 1131 and the second through hole 1321 to rotatably connect the first mounting part 110 and the second mounting part 130. The overall structure is simple and easy to process and assemble.

[0114] In one embodiment, reference is made to Figures 4 to 5 The first adapter 113 has a third through hole 1132. The door hinge 100 also includes a third fastener 160, which passes through the third through hole 1132 to be fixedly connected to the pin 120 to fix the pin 120.

[0115] The third fastener 160 can be a bolt, but is not limited to this.

[0116] In one embodiment, reference is made to Figures 4 to 5 The second mounting part 131 has a clearance hole 1312, and part of the third fastener 160 is located in the clearance hole 1312 to avoid the third fastener 160, so that the overall structure of the door hinge 100 is compact and occupies little space.

[0117] It should be understood that the third fastener 160 is not limited to cooperating with the first mounting member 110 to fix the pin 120. In this application, the third fastener 160 can also be inserted through the second adapter 132 of the second mounting member 130 and fixedly connected to the pin 120 to fix the pin 120. This should also be regarded as an embodiment of this application.

[0118] In summary, this application optimizes 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, guaranteeing the overall structural stability of the door hinge 100 during use, and ensuring that the door 300 is free from abnormalities during use, thus meeting the door usage conditions of cars without B-pillars.

[0119] The above steps are provided only to help understand the method, structure, and core ideas of this application. Those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
