[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0064] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0065] The car door is connected to the vehicle body so that it can be opened and closed. Currently, there are double-door cars on the market, whose front and rear doors are restricted on the B-pillar. The use of the B-pillar will impose certain restrictions on passengers getting on and off the car, making it inconvenient for passengers to get on and off the car. If the B-pillar is removed from this type of double-door car, due to the interference between the front and rear doors, the passengers can only open the front door first and then the rear door, or close the rear door first and then the front door, which is inconvenient.

[0066] In order to solve the above problem, an embodiment of the present application provides a vehicle in which there is no interference between a first door and a second door, and the second door can be opened or closed in any state of the first door, which is more convenient.

[0067] Figure 1The vehicle provided in the embodiment of the present application is shown, comprising: a vehicle body 1 and a first door 2 and a second door 3, wherein the first door 2 and the second door 3 are arranged on the vehicle body 1 to form a double-door; the vehicle body 1 is provided with a first hinge device 11 and a second hinge device 12, wherein the vehicle body 1 and the first door 2 are rotatably connected via the first hinge device 11, and the vehicle body 1 and the second door 3 are rotatably connected via the second hinge device 12;

[0068] In which, during the opening process of the second door 3, the second door 3 can be opened outwardly in the direction away from the first door 2 through the second hinge device 12 to avoid interference with the first door 2; during the closing process of the second door 3, the second door 3 can be closed inwardly in the direction close to the first door 2 through the second hinge device 12 to avoid interference with the first door 2.

[0069] In this embodiment, the ends of the double-opening doors, i.e., the first door 2 and the second door 3, which are far from each other, are rotatably connected to the vehicle body 1, and the ends close to each other are opened or closed relative to the vehicle body 1. The second door 3 can be opened independently when the first door 2 is in any state, and the second door 3 can be opened freely without interference from the first door 2. Correspondingly, the second door 3 can be closed independently when the first door 2 is in any state, and the second door 3 can be closed freely without interference from the first door 2. In addition, in this embodiment, one of the first door 2 and the second door 3 is a front door, and the other is a rear door. For example, in this embodiment, the first door 2 is a front door, and the second door 3 is a rear door. In other embodiments, the first door 2 is a rear door, and the second door 3 is a front door.

[0070] The vehicle provided in this embodiment has double-doors so that passengers can get on and off the vehicle more conveniently, and the second door 3 can be opened outwardly away from the first door 2 by the second hinge device 12, which means that when the second door 3 is opened, it will not interfere with the first door 2, so that the second door 3 can be opened alone, which is more convenient. When the second door is closed, the second door 3 can be closed inwardly toward the first door 2 by the second hinge device 12, and it will not interfere with the first door 2, so that the second door 3 can be closed alone, which is more convenient.

[0071] Furthermore, the vehicle provided in this embodiment is applicable to the case where there is no B-pillar, that is, the vehicle provided in this embodiment has no B-pillar, which can further facilitate passengers getting on and off the vehicle.

[0072] In some embodiments, the first hinge device 11 includes: a first mounting component 111, a pin shaft 112 and a second mounting component 113, the pin shaft 112 extends along the second direction Z, the first mounting component 111 is rotatably connected to the second mounting component 113 through the pin shaft 112, the first mounting component 111 is installed on the vehicle body 1, and the first mounting component 111 is fixedly connected to the vehicle body 1, the second mounting component 113 is installed on the first door 2, and the second mounting component 113 is fixedly connected to the first door 2.

[0073] Specifically, refer to Figures 2 to 3 , the dimension of the first mounting component 111 in the first direction X is L1 mm, and the dimension of the first mounting component 111 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 component 111 in the second direction Z to the dimension L1 mm of the first mounting component 111 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.

[0074] It can be understood that when the value of L2 / L1 is less than 0.7, the overall structure of the first mounting component 111 is smaller and the overall structural strength is lower, and the connection between the vehicle body 1 and the first door 2 cannot be effectively achieved; when the value of L2 / L1 is greater than 0.889, the overall structure of the first mounting component 111 is larger, occupying more space, affecting the structural size and strength of other components.

[0075] The present application controls the ratio of the dimension L2 mm of the first mounting component 111 in the second direction Z to the dimension L1 mm of the first mounting component 111 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 component 111 and optimize the structural size of the first mounting component 111, thereby effectively improving the structural strength and rigidity of the first mounting component 111, ensuring the overall structural stability of the first hinge device 11, and ensuring that the first door 2 is free of abnormalities during use, so as to meet the door use conditions of a car without a B-pillar design.

[0076] In one embodiment, the dimension L1 mm of the first mounting assembly 111 in the first direction X also satisfies: 90 mm ≤ L1 ≤ 100 mm. That is, the dimension L1 mm of the first mounting assembly 111 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.

[0077] The present application limits the dimension L1 mm of the first mounting component 111 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 component 111, optimize the structural size of the first mounting component 111, effectively improve the structural strength and rigidity of the first mounting component 111, and ensure the overall structural stability of the first hinge device 11.

[0078] The dimension L2 mm of the first mounting assembly 111 in the second direction Z also satisfies: 70 mm ≤ L2 ≤ 80 mm. That is, the dimension L2 mm of the first mounting assembly 111 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.

[0079] The present application limits the dimension L2 mm of the first mounting component 111 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 111, optimize the structural size of the first mounting component 111, effectively improve the structural strength and rigidity of the first mounting component 111, and ensure the overall structural stability of the first hinge device 11.

[0080] In order to improve the structural strength of the second mounting assembly 113, in one embodiment, referring to Figures 2 to 3, the dimension of the second mounting component 113 in the third direction Y is L3 mm, and the dimension of the second mounting component 113 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 component 113 in the third direction Y to the dimension L4 mm of the second mounting component 113 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.

[0081] The dimension L3 mm of the second mounting assembly 113 in the third direction Y can be obtained by disassembling the first hinge device 11 in an actual automobile, measuring the distance between two outer wall surfaces of the second mounting assembly 113 arranged opposite to each other in the third direction Y 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.

[0082] The dimension L4 mm of the second mounting assembly 113 in the second direction Z can be obtained by disassembling the first hinge device 11 in an actual automobile, measuring the distance between two outer wall surfaces of the second mounting assembly 113 arranged opposite to each other in the second direction Z 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.

[0083] It can be understood that when the value of L3 / L4 is less than 0.37, the overall structure of the second mounting assembly 113 is smaller and the overall structural strength is lower, and the connection between the vehicle body 1 and the first door 2 cannot be effectively achieved; when the value of L3 / L4 is greater than 0.43, the overall structure of the second mounting assembly 113 is larger, and more space is occupied, which affects the structural size and strength of other components.

[0084] The present application reasonably designs the overall structural size of the second mounting component 113 by setting the ratio of the dimension L3 mm of the second mounting component 113 in the third direction Y to the dimension L4 mm of the second mounting component 113 in the second direction Z within the range of 0.37 to 0.43, thereby optimizing the structural size of the second mounting component 113, effectively improving the structural strength and rigidity of the second mounting component 113, further ensuring the overall structural stability of the first hinge device 11, and ensuring that the first door 2 is free of abnormalities during use, so as to meet the door use conditions of a car without a B-pillar design.

[0085] In one embodiment, the dimension L3 mm of the second mounting assembly 113 in the third direction Y also satisfies: 55 mm ≤ L3 ≤ 65 mm. That is, the dimension L3 mm of the second mounting assembly 113 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.

[0086] The present application limits the dimension L3 mm of the second mounting component 113 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 113 and optimize the structural size of the second mounting component 113, thereby effectively improving the structural strength and rigidity of the second mounting component 113 and further ensuring the overall structural stability of the first hinge device 11.

[0087] The dimension L4 mm of the second mounting assembly 113 in the second direction Z also satisfies: 150 mm ≤ L4 ≤ 160 mm. That is, the dimension L4 mm of the second mounting assembly 113 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.

[0088] The present application limits the dimension L4 mm of the second mounting component 113 in the second direction Z to be within the range of 150 mm to 160 mm, so as to further reasonably design the overall structural size of the second mounting component 113 and optimize the structural size of the second mounting component 113, thereby effectively improving the structural strength and rigidity of the second mounting component 113 and further ensuring the overall structural stability of the first hinge device 11.

[0089] In one embodiment, referring to Figures 2 to 4 The first mounting assembly 111 includes: a first mounting portion 1111 and a first adapter portion 1112 . The first mounting portion 1111 is mounted on the vehicle body 1 . The first adapter portion 1112 is connected to a side of the first mounting portion 1111 close to the second mounting assembly 113 .

[0090] The first mounting portion 1111 and the first adapter portion 1112 are integrally die-cast.

[0091] The second mounting assembly 113 includes: a second mounting portion 1311 and a second adapter portion 1316. The second mounting portion 1311 is mounted on the first door 2. The second adapter portion 1316 is connected to a side of the second mounting portion 1311 close to the first mounting assembly 111. The second adapter portion 1316 is rotatably connected to the first adapter portion 1112 via the pin shaft 112.

[0092] Among them, the second mounting portion 1311 and the second adapter portion 1316 can be integrally formed, that is, the second mounting portion 1311 and the second adapter portion 1316 are an integral structure; the second mounting portion 1311 and the second adapter portion 1316 can also be separately provided, and the two are fixedly connected. For example, the second adapter portion 1316 is fixedly connected to the second mounting portion 1311 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 1311 and the second adapter portion 1316 are integrally die-cast.

[0093] In order to further improve the structural strength of the first mounting assembly 111, in one embodiment, referring to Figure 3 to Figure 4 The first mounting assembly 111 further includes: a bending portion 1114 , and the first mounting portion 1111 is connected to the first adapter portion 1112 through the bending portion 1114 to achieve connection between the first mounting portion 1111 and the first adapter portion 1112 .

[0094] The first mounting portion 1111 , the bending portion 1114 and the first transition portion 1112 are integrally die-cast.

[0095] Specifically, the thickness of the first mounting portion 1111 is H1 mm, and the thickness of the bending portion 1114 is H2 mm, which satisfies: H1<H2. That is, the thickness H2 mm of the bending portion 1114 is greater than the thickness H1 mm of the first mounting portion 1111, so as to further reasonably design the overall structural size of the first mounting assembly 111, so as to improve the structural strength of the bending portion 1114 of the first mounting assembly 111, thereby improving the overall structural strength and rigidity of the first mounting assembly 111, ensuring that the bending portion 1114 can effectively support the first door 2 during use, so that the first door 2 can be used without abnormality, so as to meet the door use conditions of the car without B-pillar design.

[0096] The thickness H1 mm of the first mounting portion 1111 can be obtained by disassembling the first hinge device 11 in an actual automobile, measuring the thickness of different positions of the first mounting portion 1111 in the first mounting assembly 111 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.

[0097] The thickness H2 mm of the bending portion 1114 can be obtained by disassembling the first hinge device 11 in an actual automobile, measuring the thickness of the bending portion 1114 at different positions of the first mounting assembly 111 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.

[0098] Specifically, the thickness of the bending portion 1114 can be uniform or non-uniform. When it is a structure with uniform thickness, the thickness ratio between the bending portion 1114 and the first mounting portion 1111 is fixed. If the bending portion 1114 is not a structure with uniform thickness, the thickness ratio is a range value rather than a single point data.

[0099] Usually, in order to facilitate processing and forming, the thickness of the bending portion 1114 at different positions is consistent. Even if it is inconsistent, it is based on the existence of a small thickness difference due to processing.

[0100] Specifically, the thickness H1 mm of the first mounting portion 1111 and the thickness H2 mm of the bending portion 1114 also satisfy: 1.38≤H2 / H1≤3.5. That is, the ratio of the thickness H2 mm of the bending portion 1114 to the thickness H1 mm of the first mounting portion 1111 can be controlled within the range of 1.38 to 3.5. Exemplarily, when the thickness ratio between the bending portion 1114 and the first mounting portion 1111 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 1114 and the first mounting portion 1111 is a range value, any value of H2 / H1 in 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 only given as an example, and any value in the range of 1.38 to 3.5 is within the protection scope of the present application.

[0101] The present application limits the ratio of the thickness H2 mm of the bending portion 1114 to the thickness H1 mm of the first mounting portion 1111 within the range of 1.38 to 3.5, so as to further reasonably design the overall structural size of the first mounting assembly 111, improve the structural strength of the bending portion 1114 of the first mounting assembly 111, and further improve the overall structural strength and rigidity of the first mounting assembly 111, thereby ensuring that the bending portion 1114 can effectively support the first door 2 during use, so that the first door 2 can be used without abnormalities, thereby meeting the door usage conditions of a car without a B-pillar design.

[0102] In one embodiment, the thickness H1 mm of the first mounting portion 1111 also satisfies: 8mm≤H1≤13mm. That is, the thickness H1 mm of the first mounting portion 1111 can be controlled within the range of 8mm to 13mm. Exemplarily, H1 mm can be 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm or 13mm, or a range consisting of any two of them. The above specific numerical value of L4 mm is given only as an example, and any value within the range of 8mm to 13mm is within the protection scope of this application. This application further reasonably designs the overall structural size of the first mounting assembly 111 by limiting the thickness H1 mm of the first mounting portion 1111 within the range of 8mm to 13mm, so as to enhance the structural strength of the first mounting portion 1111 of the first mounting assembly 111, effectively enhance the structural strength and rigidity of the first mounting assembly 111, and ensure the overall structural stability of the first hinge device 11.

[0103] The thickness H2 mm of the bending portion 1114 also satisfies: 18 mm ≤ H2 ≤ 28 mm. That is, the thickness H2 mm of the bending portion 1114 can be controlled within the range of 18 mm to 28 mm. Exemplarily, when the thickness of the bending portion 1114 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 1114 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.

[0104] The present application limits the thickness H2 mm of the bending portion 1114 to within the range of 18 mm to 28 mm to further improve the structural strength of the bending portion 1114 of the first mounting assembly 111, thereby improving the overall structural strength and rigidity of the first mounting assembly 111, ensuring that the bending portion 1114 can effectively support the first door 2 during use, so that the first door 2 can be used without abnormalities, thereby meeting the door usage conditions of a car without a B-pillar design.

[0105] In one embodiment, referring to Figures 3 to 5 The first mounting portion 1111 is provided with a plurality of first mounting holes 1011, and each first mounting hole 1011 is respectively arranged at a corner area of ​​the first mounting portion 1111. The present application provides a plurality of first mounting holes 1011 on the first mounting portion 1111, so as to utilize the plurality of first mounting holes 1011 to realize the installation between the first mounting assembly 111 and the vehicle body 1, thereby improving the mounting structural strength and modality of the first mounting assembly 111, ensuring that the first hinge device 11 can effectively support the first vehicle door 2 during use, so that the first vehicle door 2 can be used without abnormality, thereby meeting the door use conditions of a vehicle without a B-pillar design.

[0106] Illustratively, in the present application, four first mounting holes 1011 are opened on the first mounting portion 1111 , and the four first mounting holes 1011 are respectively arranged at four corner areas of the first mounting portion 1111 .

[0107] In one embodiment, the first hinge device 11 further includes: a plurality of first fasteners 114 , each first fastener 114 is respectively passed through a corresponding first mounting hole 1011 , and the first fastener 114 is fixedly connected to the vehicle body 1 to achieve installation of the first mounting assembly 111 on the vehicle body 1 .

[0108] The first fastener 114 may be a bolt, but is not limited thereto.

[0109] In order to further improve the structural strength of the second mounting assembly 113, in one embodiment, referring to Figure 5 , the thickness of the second mounting portion 1311 is H3 mm, satisfying: 7mm≤H3≤15mm. That is, the thickness H3 mm of the second mounting portion 1311 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 1311 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 assembly 113, thereby improving the structural strength of the second mounting portion 1311 in the second mounting assembly 113, effectively improving the structural strength and rigidity of the second mounting assembly 113, and ensuring the overall structural stability of the first hinge device 11.

[0110] The thickness H3 mm of the second mounting portion 1311 can be obtained by disassembling the first hinge device 11 in an actual automobile, measuring the thickness of different positions of the second mounting portion 1311 in the second mounting assembly 113 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.

[0111] In one embodiment, referring to Figures 2 to 4 The second mounting portion 1311 is provided with a plurality of second mounting holes 1312, and each second mounting hole 1312 is respectively arranged at the corner area of ​​the second mounting portion 1311. In the present application, a plurality of second mounting holes 1312 are provided on the second mounting portion 1311, so as to realize the installation between the second mounting assembly 113 and the first door 2 by utilizing the plurality of second mounting holes 1312, thereby improving the mounting structural strength and modality of the second mounting assembly 113, ensuring that the first hinge device 11 can effectively support the first door 2 during use, so that the first door 2 can be used without abnormality, so as to meet the door use conditions of the car without B-pillar design.

[0112] Exemplarily, in the present application, four second mounting holes 1312 are provided on the second mounting portion 1311, and the four second mounting holes 1312 are respectively provided at four corner areas of the second mounting portion 1311. Specifically, three second mounting holes 1312 are provided at the upper portion of the second mounting portion 1311, and one second mounting hole 1312 is provided at the lower portion of the second mounting portion 1311.

[0113] In one embodiment, the first hinge device 11 further includes: a plurality of second fasteners 115 , each second fastener 115 is respectively passed through a corresponding second mounting hole 1312 , and the second fastener 115 is fixedly connected to the first door 2 to achieve installation of the second mounting assembly 113 on the first door 2 .

[0114] The second fastener 115 may be a bolt, but is not limited thereto.

[0115] In order to achieve the door opening limit of the first door 2, in one embodiment, referring to Figures 2 to 9 The first installation assembly 111 also includes: a first limiting portion 1113 , and the first limiting portion 1113 is connected to the first adapter portion 1112 .

[0116] The second installation assembly 113 further includes: a second limiting portion 1313 , the second limiting portion 1313 is connected to the second adapter portion 1316 , and the second limiting portion 1313 can selectively abut against the first limiting portion 1113 to achieve the door opening limit of the first vehicle door 2 .

[0117] Among them, the first limit part 1113 and the first adapter part 1112 can be integrally formed, that is, the first limit part 1113 and the first adapter part 1112 are an integral structure; the first limit part 1113 and the first adapter part 1112 can also be separately provided, and the two are fixedly connected. For example, the first limit part 1113 is fixedly connected to the first adapter part 1112 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 limit part 1113 and the first adapter part 1112 are integrally die-cast.

[0118] The second position-limiting portion 1313 and the second transition portion 1316 can be integrally formed, that is, the second position-limiting portion 1313 and the second transition portion 1316 are an integral structure; the second position-limiting portion 1313 and the second transition portion 1316 can also be separately provided, and the two are fixedly connected, and illustratively, the second position-limiting portion 1313 is fixedly connected to the second transition portion 1316 by welding or other processes. This is not specifically limited in this application, and can be specifically set according to actual circumstances. Exemplarily, in this application, the second position-limiting portion 1313 and the second transition portion 1316 are integrally die-cast.

[0119] It can be understood that the first door 2 of the automobile has two states: open and closed. Figure 8 When the first door 2 is in the open state, the second limiting portion 1313 does not contact the first limiting portion 1113. When the first door 2 is opened, the second mounting assembly 113 is synchronously driven to rotate around the central axis of the pin shaft 112. Fig. 9As shown, when the first door 2 is opened to a certain angle, the second limiting portion 1313 abuts against the first limiting portion 1113 to limit the second mounting assembly 113, and then limit the first door 2 to prevent damage to components caused by excessive door opening angle.

[0120] In one embodiment, referring to Figures 2 to 4 A first through hole 1116 is formed on the first adapter portion 1112, and a second through hole 1314 is formed on the second adapter portion 1316; the pin shaft 112 is passed through the first through hole 1116 and the second through hole 1314 to rotatably connect the first mounting component 111 with the second mounting component 113. The overall structure is simple and easy to process and assemble.

[0121] In one embodiment, referring to Figures 5 and 6 The first adapter portion 1112 is provided with a third through hole 1115. The first hinge device 11 further includes a third fastener 116, which is passed through the third through hole 1115 to be fixedly connected with the pin shaft 112, so as to fix the pin shaft 112.

[0122] The third fastener 116 may be a bolt, but is not limited thereto.

[0123] In one embodiment, referring to Figures 5 and 6 The second mounting portion 1311 is provided with an avoidance hole 1315 , and part of the third fastener 116 is located in the avoidance hole 1315 to avoid the third fastener 116 , so that the overall structure of the first hinge device 11 is compact and occupies a small space.

[0124] It should be understood that the third fastener 116 is not limited to cooperating with the first mounting component 111 to achieve fixation of the pin 112. In the present application, the third fastener 116 can also be passed through the second adapter portion 1316 of the second mounting component 113 and fixedly connected to the pin 112 to achieve fixation of the pin 112, which should also be regarded as an embodiment of the present application.

[0125] In some embodiments, the second hinge device 12 can rotate through a first angle α to drive the second door 3 to break away from the interference of the first door 2 .

[0126] In this embodiment, when the second door 3 is opened, the second hinge device 12 rotates the first angle α, driving the second door 3 to move away from the first door 2 and escape from the interference of the first door 2. When the second door 3 is closed, the second hinge device 12 rotates the first angle α, driving the second door 3 to move toward the first door 2 and escape from the interference of the first door 2.

[0127] In some embodiments, the second hinge device 12 can rotate through a second angle β to drive the second door 3 to open or close.

[0128] In this embodiment, when the second door 3 is opened, the second hinge device 12 rotates the second angle β, driving the second door 3 to move away from the vehicle body 1 to open the second door 3; when the second door 3 is closed, the second hinge device 12 rotates the second angle β, driving the second door 3 to move toward the vehicle body 1 to close the second door 3.

[0129] It should be noted that when the second door 3 is in the closed state, Fig.16 As shown, the second door 3 and the vehicle body 1 are in a parallel state. After the second hinge device 12 rotates by a first angle α, driving the second door 3 to move away from the first door 2, as shown in FIG. Fig.17 As shown, the second door 3 and the vehicle body 1 are still in a parallel state, and after the second hinge device 12 rotates the second angle β to drive the second door 3 to move away from the vehicle body 1, as shown in FIG. Fig.18 As shown, the second door 3 is in an open state, and the angle between the second door 3 and the vehicle body 1 is β.

[0130] Among them, in the process of the second door 3 from closing to opening, the second hinge device 12 first rotates by the first angle α, driving the second door 3 to move away from the first door 2, so that the second door 3 is free from the interference of the first door 2, and then the second hinge device 12 rotates by the second angle β to drive the second door 3 to move away from the vehicle body 1, and then the door is opened.

[0131] During the process of the second door 3 being opened and closed, the second hinge device 12 first rotates by the second angle β to drive the second door 3 to move toward the direction close to the vehicle body 1, so that the second door 3 is parallel to the vehicle body. Then, the second hinge device 12 rotates by the first angle α to drive the second door 3 to move toward the direction close to the first door 2 to close the door.

[0132] In some embodiments, the second hinge device 12 includes a third mounting assembly 121, and the third mounting assembly 121 is mounted on the vehicle body 1. The second hinge device 12 also includes a rotating arm assembly 122, and the rotating arm assembly 122 is rotatably connected to the third mounting assembly 121, and the rotating arm assembly can rotate at a first angle α or a second angle β. The second hinge device 12 also includes a fourth mounting assembly 123, and the fourth mounting assembly 123 is mounted on the second vehicle door 3, and the fourth mounting assembly 123 is rotatably connected to the rotating arm assembly 122.

[0133] In the above manner, the rotating arm assembly 122 of this embodiment is rotatably connected to the third mounting assembly 121 and the fourth mounting assembly 123 respectively, that is, the second hinge device 12 of this embodiment adopts a double rotation axis design. The connection between the rotating arm assembly 122 and the third mounting assembly 121 has a first rotation axis O1, and the rotating arm assembly 122 and the third mounting assembly 121 can rotate relative to each other around the first rotation axis O1. The connection between the rotating arm assembly 122 and the fourth mounting assembly 123 has a second rotation axis O2, and the rotating arm assembly 122 and the fourth mounting assembly 123 can rotate relative to each other around the second rotation axis O2. In this way, the second hinge device 12 of this embodiment constrains the motion trajectory of the second door 3 through the cooperation of the first rotation axis O1 and the second rotation axis O2, so that the second door 3 can achieve a specific compound motion during the opening and closing process, which can reduce the risk of the second door 3 interfering with other structures during the opening and closing process. Especially for a vehicle with a double-door design without a B-pillar, the second hinge device 12 of this embodiment can reduce the risk of interference between the second door 3 and other doors (such as the first door 2 mentioned above).

[0134] For example, Fig.11 and Fig.12 As shown, the movement trajectory of the second door 3 in this embodiment includes a closed position S1, a transition position S2, and an open position S3. The angle at which the second door 3 is opened relative to the vehicle body 1 at the open position S3 is greater than the angle at which the second door 3 is opened relative to the vehicle body 1 at the closed position S1. The second door 3 moves from the closed position S1 to the open position S3 via the transition position S2 during the opening process, and moves from the open position S3 to the closed position S1 via the transition position S2 during the closing process. Taking the opening process of the second door 3 as an example, during the movement of the second door 3 from the closed position S1 to the transition position S2, the rotating arm assembly 122 and the third mounting assembly 121 rotate relative to each other, and the rotating arm assembly 122 and the fourth mounting assembly 123 rotate relative to each other. During the movement of the second door 3 from the closed position S1 to the transition position S2, the rotating arm assembly 122 and the third mounting assembly 121 stop rotating relative to each other, while the rotating arm assembly 122 and the fourth mounting assembly 123 continue rotating relative to each other, so that the second door 3 moves from the transition position S2 to the open position S3, thereby completing the opening process of the second door 3.

[0135] Please also read Fig.14 and Fig.15 , Fig.14 This is a schematic structural diagram of an embodiment of the hinge device of the present application installed on a vehicle body. Fig.15 yes Fig.14 The hinge device shown is installed on the vehicle body in another state.

[0136] In one embodiment, the vehicle body 1 has an installation space inside, and the vehicle body 1 is further provided with an avoidance through hole 101 communicating with the installation space. The third installation assembly 121 is installed in the installation space, and the rotating arm assembly 122 is movably arranged in the avoidance through hole 101, so that the rotating arm assembly 122 can be rotatably connected to the third installation assembly 121 and the fourth installation assembly 123 respectively. The fourth installation assembly 123 and the rotating arm assembly 122 are detachably arranged.

[0137] In addition, the vehicle body 1 of this embodiment is also provided with an avoidance through hole 101 connected to the installation space, and the rotating arm assembly 122 can be movably inserted into the avoidance through hole 101, so that the rotating arm assembly 122 can be connected to the third installation assembly 121 and the fourth installation assembly 123 respectively. In this embodiment, the fourth installation assembly 123 and the rotating arm assembly 122 are detachably arranged, which can facilitate the installation of the second hinge device 12, and the fourth installation assembly 123 does not need to pass through the avoidance through hole 101, allowing the avoidance through hole 101 to be designed with a smaller opening area, which is conducive to ensuring the structural strength of the vehicle body 1. If the fourth installation assembly 123 and the rotating arm assembly 122 are not detachable, it means that the entire fourth installation assembly 123 needs to pass through the avoidance through hole 101 to be installed on the second door 3, which results in the avoidance through hole 101 needing to be designed with a larger opening area, which will weaken the structural strength of the vehicle body 1 to a certain extent.

[0138] Of course, in other embodiments of the present application, the rotating arm assembly 122 and the third mounting assembly 121 are detachably arranged, which can further facilitate the installation of the second hinge device 12, and is not limited here.

[0139] It should be noted that, for the example in which the second door 3 is the rear door of the vehicle, the installation space is located in the C-pillar structure 102 of the vehicle body 1. In this embodiment, at least part of the third installation assembly 121 and the rotating arm assembly 122 are located in the C-pillar structure 102 of the vehicle body 1, which not only enhances the structural strength of the vehicle body 1 and improves the safety performance of the overall structure, but also optimizes the structural layout of the second hinge device 12, which is conducive to improving space utilization. In addition, the second hinge device 12 has a compact structure, which is conducive to the installation design of the second hinge device 12 embedded in the C-pillar structure 102, while saving space in the vehicle body 1. In addition, the second hinge device 12 is forged as a whole, which is conducive to ensuring the structural stability and safety of the second hinge device 12 and meeting strict automotive industry standards.

[0140] See also Fig.13In one embodiment, the rotating arm assembly 122 includes a first rotating arm 1221 and a second rotating arm 1222. The first rotating arm 1221 is rotatably connected to the third mounting assembly 121 and the fourth mounting assembly 123, respectively, and the first rotating arm 1221 can rotate by a first angle α. The second rotating arm 1222 is rotatably connected to the third mounting assembly 121 and the fourth mounting assembly 123, respectively, and the second rotating arm 1222 can rotate by a second angle β. The first rotating arm 1221 and the second rotating arm 1222 can rotate relative to the third mounting assembly 121 around the first rotation axis O1, and the first rotating arm 1221 and the second rotating arm 1222 can rotate relative to the fourth mounting assembly 123 around the second rotation axis O2. The first rotating arm 1221 and the fourth mounting assembly 123 are detachably arranged, and the second rotating arm 1222 and the fourth mounting assembly 123 are detachably arranged, so that the rotating arm assembly 122 and the fourth mounting assembly 123 can be detachably arranged. The avoidance through hole 101 includes a first avoidance through hole 1101 and a second avoidance through hole 1102 which are spaced apart from each other. The first rotating arm 1221 is movably disposed in the first avoidance through hole 1101 , and the second rotating arm 1222 is movably disposed in the second avoidance through hole 1102 .

[0141] In the above manner, the rotating arm assembly 122 is connected to the third mounting assembly 121 and the fourth mounting assembly 123 through the first rotating arm 1221 and the second rotating arm 1222, respectively, and the first rotating arm 1221 and the second rotating arm 1222 can cooperate to improve the connection strength. In addition, the avoidance through hole 101 is designed for the first rotating arm 1221 and the second rotating arm 1222, namely the first avoidance through hole 1101 and the second avoidance through hole 1102, respectively, so that the avoidance through hole 101 can have a smaller opening area under the premise of ensuring the overall structural stability of the second hinge device 12, which is conducive to ensuring the structural strength of the vehicle body 1. If only one avoidance through hole 101 is designed, the first rotating arm 1221 and the second rotating arm 1222 both pass through the avoidance through hole 101 to connect to the fourth mounting assembly 123, and the opening area of ​​the avoidance through hole 101 is bound to be greater than the sum of the opening areas of the first avoidance through hole 1101 and the second avoidance through hole 1102, which will undoubtedly weaken the structural strength of the vehicle body 1.

[0142] Fig.14 The state of the first rotating arm 1221 and the second rotating arm 1222 when the second door 3 is closed is shown. Fig.15 The state of the first rotating arm 1221 and the second rotating arm 1222 when the second door 3 is opened is shown.

[0143] Further, the first rotating arm 1221 and the second rotating arm 1222 are spaced apart along the height direction of the vehicle body 1. Correspondingly, the first avoidance through hole 1101 and the second avoidance through hole 1102 are also spaced apart along the height direction of the vehicle body 1, so that the first rotating arm 1221 can be movably disposed in the first avoidance through hole 1101, and the second rotating arm 1222 can be movably disposed in the second avoidance through hole 1102.

[0144] Optionally, both the first rotating arm 1221 and the second rotating arm 1222 may be in a gooseneck shape, etc., which is not limited here.

[0145] In one embodiment, the rotating arm assembly 122 further includes a first rotating connection member 1223 and a second rotating connection member 1224. The first rotating arm 1221 is provided with a first connection hole, the fourth mounting assembly 123 is provided with a second connection hole, and the first rotating connection member 1223 is detachably inserted through the first connection hole and the second connection hole, so that the first rotating arm 1221 is rotatably connected to the fourth mounting assembly 123. The second rotating arm 1222 is provided with a third connection hole, the fourth mounting assembly 123 is provided with a fourth connection hole, and the second rotating connection member 1224 is detachably inserted through the third connection hole and the fourth connection hole, so that the second rotating arm 1222 is rotatably connected to the fourth mounting assembly 123. The central axis of the first rotating connection member 1223 and the central axis of the second rotating connection member 1224 both coincide with the second rotation axis O2.

[0146] In one embodiment, the rotating arm assembly 122 further includes a third rotating connection member 1225. The third rotating connection member 1225 is disposed through the third mounting assembly 121, the first rotating arm 1221, and the second rotating arm 1222, so that the first rotating arm 1221 and the second rotating arm 1222 are both rotatably connected to the third mounting assembly 121. The central axis of the third rotating connection member 1225 coincides with the first rotating axis O1.

[0147] In one embodiment, the third mounting assembly 121 includes a mounting seat 1211 and a connecting arm 1212. The mounting seat 1211 is used to connect with the vehicle body 1, and the connecting arm 1212 is protruding from the mounting seat 1211, and the connecting arm 1212 is rotatably connected to the rotating arm assembly 122. Specifically, the first rotating arm 1221 and the second rotating arm 1222 are both rotatably connected to the connecting arm 1212 through the third rotating connecting member 1225. The mounting seat 1211 is used to abut against the rotating arm assembly 122 to limit the rotation of the rotating arm assembly 122. During the closing process of the second door 3, the second door 3 moves from the transition position to the closed position, and at this time, the rotating arm assembly 122 rotates toward the third mounting assembly 121 until the first rotating arm 1221 and the second rotating arm 1222 abut against the mounting seat 1211, and the mounting seat 1211 limits the first rotating arm 1221 and the second rotating arm 1222 from further rotating.

[0148] In one embodiment, the rotating arm assembly 122 further includes a first support member 1226, which is detachably supported between the first rotating arm 1221 and the second rotating arm 1222. The first support member 1226 is configured to enhance the structural strength of the rotating arm assembly 122, thereby facilitating the overall structural stability of the second hinge device 12. Furthermore, the first support member 1226 and the first rotating arm 1221 and the second rotating arm 1222 are detachably arranged, which means that during the installation process of the second hinge device 12, the first support member 1226 does not need to pass through the avoidance through hole 101, further allowing the avoidance through hole 101 to be designed with a smaller opening area, thereby facilitating the structural strength of the vehicle body 1.

[0149] Specifically, the first support member 1226 is arranged close to the fourth mounting assembly 123. In this embodiment, the first support member 1226 is arranged to be detachably supported between the first rotating arm 1221 and the second rotating arm 1222. The first support member 1226 and the first rotating arm 1221 and the second rotating arm 1222 are detachably arranged, which means that during the installation process of the second hinge device 12, the first support member 1226 does not need to pass through the avoidance through hole 101, and further allows the avoidance through hole 101 to be designed with a smaller opening area, which is conducive to ensuring the structural strength of the vehicle body 1. In particular, for the case where the first support member 1226 is arranged close to the fourth mounting assembly 123 in this embodiment, if the first rotating arm 1221 and the second rotating arm 1222 are not detachable from the fourth mounting assembly 123, the first support member 1226 must be required to pass through the avoidance through hole 101 during the installation process of the second hinge device 12, resulting in the need to design a larger opening area for the avoidance through hole 101, which weakens the structural strength of the vehicle body 1.

[0150] In one embodiment, the rotating arm assembly 122 further includes a second support member 1227, which is supported between the first rotating arm 1221 and the second rotating arm 1222, and the second support member 1227 is disposed close to the third mounting assembly 121. In this embodiment, the first support member 1226 and the second support member 1227 cooperate to enhance the structural strength of the rotating arm assembly 122, thereby facilitating the overall structural stability of the second hinge device 12.

[0151] In one embodiment, a second hinge device 12 is provided. The second hinge device 12 includes a third mounting assembly 121, and the third mounting assembly 121 is used to connect to the vehicle body 1. The second hinge device 12 also includes a rotating arm assembly 122, and the rotating arm assembly 122 is rotatably connected to the third mounting assembly 121. The second hinge device 12 also includes a fourth mounting assembly 123, and the fourth mounting assembly 123 is used to connect to the second door 3 of the vehicle, and the fourth mounting assembly 123 is rotatably connected to the rotating arm assembly 122, and the fourth mounting assembly 123 and the rotating arm assembly 122 are detachably arranged.

[0152] In the above manner, the rotating arm assembly 122 of the second hinge device 12 is rotatably connected to the third mounting assembly 121 and the fourth mounting assembly 123, respectively. That is, the second hinge device 12 of this embodiment adopts a double rotating shaft design, which can reduce the risk of the second door 3 interfering with other structures during the opening and closing process. In particular, for a vehicle with a B-pillar-free double-door design, the second hinge device 12 of this embodiment can reduce the risk of the second door 3 interfering with other doors. In addition, the fourth mounting assembly 123 of this embodiment is detachably arranged from the rotating arm assembly 122, which can facilitate the installation of the second hinge device 12.

[0153] The vehicle further includes a first driving device 4 for driving the second hinge device 12 to rotate a first angle α or a second angle β to open or close the second door 3 .

[0154] The first driving device 4 includes a hinge assembly 401 and a first driving assembly 402 .

[0155] Reference Figures 16 to 18 The hinge assembly 401 includes a rotating arm 4010, and the rotating arm 4010 includes a first end 4111 and a second end 4112 disposed opposite to each other. Figure 2 , Figures 4 to 6 The first end 4111 is used for rotational connection with the vehicle body 1 , and the second end 4112 is used for rotational connection with the second door 3 of the vehicle body 1 , specifically, the second end 4112 is used for rotational connection with the connection side 31 of the second door 3 .

[0156] Reference Figure 16 to Figure 18 as well as Figure 20-21 The first driving assembly 402 includes a driving arm 41 , and the driving arm 41 includes a connecting end 411 and a driving end 412 that are arranged opposite to each other. The connecting end 411 is used for rotationally connecting with the vehicle body 1 , and the driving end 412 is used for connecting with the second vehicle door 3 .

[0157] Among them, the rotating arm 4010 can rotate a first angle α with the first end 4111 as the axis, so that the second door 3 switches between the closed state Z1 and the first open state Z2; the driving end 412 can move along the length direction of the second door 3 to drive the second door 3 to rotate a second angle β with the second end 4112 as the axis, so that the second door 3 switches between the second open state Z3 and the first open state Z2.

[0158] In some embodiments, the first driving device 4 also includes a first sensor, which is arranged on the driving member 42. The first sensor is used to sense the rotation angle of the rotating arm assembly 122. Before the first sensor senses that the rotating arm assembly 122 rotates to the first angle α, the driving member 42 is used to limit the rotating arm assembly 122 from rotating to the second angle β.

[0159] In this embodiment, the first sensor may be a Hall sensor. In other embodiments, the first sensor may also be an angle detector. In this embodiment, the rotation angle of the rotating arm assembly 122 can be obtained through the first sensor, so that when the second door 3 is opened or closed, the first sensor can sense that the rotating arm assembly 122 rotates to the first angle α, and the driving member 42 is used to limit the rotating arm assembly 122 from rotating to the second angle β.

[0160] The first driving device 4 provided in the embodiment of the present application is provided with a hinge assembly 401 and a first driving assembly 402 to realize a rotational connection between the vehicle body 1 and the second door 3 of the vehicle body 1. Specifically, the hinge assembly 401 includes a rotating arm 4010, and the rotating arm 4010 includes a first end 4111 and a second end 4112 arranged opposite to each other. The first end 4111 of the rotating arm 4010 is used for rotational connection with the vehicle body 1, and the second end 4112 is used for rotational connection with the second door 3. The first driving assembly 402 includes a driving arm 41, and the driving arm 41 includes a connecting end 411 and a driving end 412 arranged opposite to each other. The connecting end 411 is used for rotational connection with the vehicle body 1, and the driving end 412 is used for connection with the second door 3.

[0161] The rotating arm 4010 can rotate by a first angle α with the first end 4111 as the axis, so that the second door 3 switches between the closed state Z1 and the first open state Z2, and the driving end 412 of the driving arm 41 can move along the length direction of the second door 3 to drive the second door 3 to rotate by a second angle β with the second end 4112 of the rotating arm 4010 as the axis, so that the second door 3 switches between the second open state Z3 and the first open state Z2. Thus, the rotating arm 4010 in the hinge assembly 401 and the driving arm 41 in the first driving assembly 402 form a dual driving structure for the second door 3.

[0162] In some embodiments, the first driving assembly 402 further includes a driving member 42, which is used to be installed on the second door 3, and the driving end 412 of the driving arm 41 is connected to the driving member 42, and the driving member 42 can drive the driving end 412 to move along the length direction of the second door 3. The driving member 42 is provided to drive the driving end 412 to move along the length direction of the second door 3, and combined with the structural design of the connection end 411 of the driving arm 41 and the third mounting portion 4022 being rotatably connected, the driving end 412 can generate a force through the driving arm 41 during the movement, and the driving arm 41 then generates a reaction force on the second door 3 through the driving end 412, so as to drive the second door 3 to rotate around the second end 4112 as the axis, thereby ensuring the rotation stability of the second door 3, and improving the automaticity of opening and closing the second door 3, saving the passenger's effort in opening and closing the second door 3.

[0163] In some embodiments, the first driving assembly 402 further includes: a transmission rod 43 and a sliding member 44, wherein the transmission rod 43 is used to be installed on the second door 3 and extends along the length direction of the second door 3, one end of the transmission rod 43 is connected to the driving member 42, the sliding member 44 is arranged on the transmission rod 43, the driving end 412 of the driving arm 41 is connected to the sliding member 44, the driving member 42 is a rotary motor, the driving member 42 can drive the transmission rod 43 to drive the sliding member 44 to move along the length direction of the second door 3, and the sliding member 44 drives the driving end 412 to move along the length direction of the second door 3, thereby driving the second door 3 to switch between the first opening state Z2 and the second opening state Z3. The matching design of the transmission rod 43 and the sliding member 44 can ensure the stability of the driving end 412 moving along the length direction of the second door 3, thereby ensuring the stability and smoothness of the switching of the second door 3 between the first opening state Z2 and the second opening state Z3.

[0164] In some embodiments, the first driving assembly 402 further includes a stopper 54, the stopper 54 includes an elastic position 541 and a stopper 542, the elastic position 541 and the stopper 542 are sequentially connected, the stopper 542 is installed on the second door 3 through the elastic position 541, and the end of the stopper 542 away from the elastic position 541 is toward the transmission rod 43, referring to Fig.11 The sliding member 44 is provided with a groove 441, wherein the sliding member 44 moves along the length direction of the second door 3, the stopper 542 can be inserted into the groove 441 to limit the movement of the sliding member 44, and the driving member 42 can drive the transmission rod 43 to drive the sliding member 44 to separate from the stopper 542. The matching design of the elastic part 541 and the stopper 542 in the limiting member 54 can keep the sliding member 44 in a specific position during the movement of the sliding member 44 along the length direction of the second door 3, so that the second door 3 is kept in a specific state, ensuring the stability and smoothness of the opening or closing of the second door 3.

[0165] In some embodiments, reference Figure 16 to Figure 19 The first driving component 402 also includes a receiving member 4021, which extends along the length direction of the second door 3. The receiving member 4021 is arranged on the side of the second door 3 facing the vehicle body 1. The receiving member 4021 has a receiving groove on the side facing the vehicle body 1. The driving member 42, the transmission rod 43, the sliding member 44 and the limiting member 54 are all arranged in the receiving groove of the receiving member 4021, and the end of the elastic position 541 away from the stop position 542 abuts against the bottom of the receiving groove.

[0166] In some embodiments, reference Figure 4 , the second door 3 moves from the closed state Z1 to the first open state Z2, and the movement trajectory of the second door 3 is the first trajectory A1, that is, the movement trajectory of the movable side 32 of the second door 3 forms the first trajectory A1, and the shape of the first trajectory A1 is an arc. Specifically, in the process of the second door 3 moving from the closed state Z1 to the first open state Z2, along the first trajectory A1, the movable side 32 of the second door 3 moves in the direction away from the first door 2, thereby avoiding the interference between the second door 3 and the first door 2 during the opening process, and ensuring the smooth opening of the second door 3; conversely, the second door 3 moves from the first open state Z2 to the closed state Z1, and the movement trajectory of the second door 3 is also the first trajectory A1. Specifically, in the process of the second door 3 moving from the first open state Z2 to the closed state Z1, along the first trajectory A1, the movable side 32 of the second door 3 moves in the direction close to the first door 2, thereby avoiding the interference between the second door 3 and the first door 2 during the closing process, and ensuring the smooth closing of the second door 3.

[0167] In some embodiments, reference Fig.18 , the second door 3 moves from the first opening state Z2 to the second opening state Z3, and the movement trajectory of the second door 3 is the second trajectory A2, that is, the movement trajectory of the active side 32 of the second door 3 forms the second trajectory A2, and the shape of the second trajectory A2 is an arc. Specifically, in the process of the second door 3 moving from the first opening state Z2 to the second opening state Z3, along the second trajectory A2, the active side 32 of the second door 3 further moves away from the first door 2, and the length of the second trajectory A2 is greater than that of the first trajectory A1, thereby realizing a large-angle opening of the second door 3 and increasing the opening amplitude of the second door 3.

[0168] In some embodiments, reference Figure 16 to Figure 19 The hinge assembly 401 further includes a first mounting member 4011 and a second mounting member 4012. Figure 2 , Figure 4 as well as Figure 6The first mounting member 4011 is used to be mounted on the vehicle body 1, and the rotating arm 4010 is rotatably connected to the first mounting member 4011 through the first end 4111. The second mounting member 4012 is used to be mounted on the second door 3, and the second door 3 is rotatably connected to the second end 4112 through the second mounting member 4012. The provision of the first mounting member 4011 can ensure the connection stability between the rotating arm 4010 and the vehicle body 1, and further ensure the stability of the rotating arm 4010 rotating around the first end 4111 as the axis. The provision of the second mounting member 4012 can ensure the connection stability between the rotating arm 4010 and the second door 3, and further ensure the stability of the second door 3 rotating around the second end 4112 as the axis.

[0169] In some embodiments, reference Figure 16 to Figure 19 The first mounting member 4011 is provided with a first protruding portion 4013 protruding from one end adjacent to the first end 4111. Figure 8 , a second protrusion 4113 is protruded from the first end 4111, and when the second door 3 moves from the closed state Z1 to the first open state Z2, the first protrusion 4013 abuts against the second protrusion 4113 to limit the rotation of the rotating arm 4010. The matching design of the first protrusion 4013 and the second protrusion 4113 enables the first protrusion 4013 to abut against the second protrusion 4113 when the second door 3 moves from the closed state Z1 to the first open state Z2, so that the rotating arm 4010 does not continue to rotate about the first end 4111 after rotating about the first end 4111 as the axis by the first angle α, that is, when the second door 3 continues to move from the first open state Z2 to the second open state Z3, the rotating arm 4010 remains stationary, ensuring that the second door 3 moves from the first open state Z2 to the second open state Z3 smoothly and smoothly.

[0170] In some embodiments, reference Figure 16 to Figure 19 The first mounting member 4011 includes a first mounting seat 4014 and a first connecting arm 4015 connected to each other. Figure 2 , Figure 4 as well as Figure 6 The first mounting member 4011 is mounted on the vehicle body 1 through the first mounting seat 4014. Specifically, the first mounting seat 4014 is detachably mounted on the vehicle body 1 through bolts. One end of the first connecting arm 4015 is rotatably connected to the first end 4111 of the rotating arm 4010, and the other end is fixedly connected to the first mounting seat 4014 to ensure the installation stability between the first mounting seat 4014 and the vehicle body 1, thereby ensuring the connection stability between the rotating arm 4010 and the vehicle body 1. Figure 4 , Figure 6 as well as Figure 8 The first protrusion 4013 is protrudingly disposed at one end of the first connecting arm 4015 adjacent to the first end 4111 .

[0171] In some embodiments, reference Figure 16 to Figure 19 The second mounting member 4012 is provided with a third protrusion 4016 protruding from one end adjacent to the second end 4112. Figure 2 , Figure 4 as well as Figure 6 When the second door 3 is in the closed state Z1 and the second door 3 is in the first open state Z2, there is a gap between the third protrusion 4016 and the second end 4112 of the rotating arm 4010, that is, the third protrusion 4016 does not contact the second end 4112. Figure 6 and Figure 8 , Figure 6 It is a schematic diagram of the structure when the second door 3 moves to the second open state Z3. Figure 8 The figure shows a schematic diagram of the structural state of the rotating arm 4010 when the second door 3 moves to the second opening state Z3. When the second door 3 moves to the second opening state, the third protrusion 4016 abuts against the second end 4112 to limit the rotation of the second door 3. The third protrusion 4016 can block and limit the rotation of the second door 3 when the second door 3 rotates to the second opening state Z3, thereby preventing the second door 3 from opening too much, avoiding the damage caused by the collision with the vehicle body 1 due to the second door 3 opening too much, ensuring the opening safety of the second door 3, and ensuring the service life and use safety of the vehicle body 1.

[0172] In some embodiments, reference Figure 16 to Figure 19 The second mounting member 4012 includes a second mounting seat 4017 and a second connecting arm 4018. The second mounting member 4012 is installed on the second door 3 through the second mounting seat 4017. Specifically, the second mounting seat 4017 is detachably installed on the second door 3 through bolts. One end of the second connecting arm 4018 is fixedly connected to the second mounting seat 4017, and the other end is rotatably connected to the second end 4112 of the rotating arm 4010 to ensure the installation stability between the second mounting seat 4017 and the second door 3, thereby ensuring the connection stability between the rotating arm 4010 and the second door 3. The third protrusion 4016 is protrudingly arranged at one end of the second connecting arm 4018 adjacent to the second end 4112.

[0173] In some embodiments, reference Fig.19, the third protrusion 4016 can rotate to a third angle θ, satisfying: β=θ. Specifically, the second mounting seat 4017 is mounted on the second door 3, and the second connecting arm 4018 is fixedly connected to the second mounting seat 4017, so that when the second door 3 rotates from the first opening state Z2 to the second opening state Z3, the second door 3 can drive the second connecting arm 4018 and the third protrusion 4016 to rotate synchronously through the second mounting seat 4017, thereby making the rotation angle β of the second door 3 the same as the rotation angle θ of the third protrusion 4016, so that when the second door 3 rotates and moves to the second opening state Z3, the third protrusion 4016 can abut against the second end 4112 of the rotating arm 4010 to prevent the second door 3 from continuing to rotate with the second end 4112 as the axis, thereby ensuring the opening safety of the second door 3 and ensuring the service life and use safety of the vehicle body 1.

[0174] In some embodiments, a rotating drive member (not shown in the figure) for driving the rotating arm 4010 to rotate about the first end 4111 as an axis may be provided on the vehicle body 1, thereby automatically driving the rotating arm 4010 to drive the second door 3 to switch between the closed state Z1 and the first open state Z2. The rotating drive member may be a cylinder or a telescopic motor. In some other implementations, the second door 3 may be manually driven by the passengers to switch between the closed state Z1 and the first open state Z2, that is, the rotating arm 4010 is driven to rotate about the first end 4111 as an axis by the second door 3. Specifically, the passengers drive the second door 3 to switch between the closed state Z1 and the first open state Z2 through a handle (not shown in the figure) provided at one end of the second door 3 adjacent to the first door 2 along its length direction.

[0175] In some embodiments, reference Figure 16 to Figure 19 The hinge assembly 401 also includes a first rotating shaft 421 and a second rotating shaft 431. The first rotating shaft 421 is inserted between the first end 4111 and the first connecting arm 4015, so that the rotating arm 4010 can rotate a first angle α around the first rotating shaft 421 to ensure the rotational stability of the rotating arm 4010. The second rotating shaft 431 is inserted between the second end 4112 and the second connecting arm 4018, so that the second door 3 can rotate a second angle β around the second rotating shaft 431 through the second mounting member 4012 to ensure the rotational stability of the second door 3.

[0176] In some embodiments, reference Figure 16 to Figure 21 The first driving component 402 also includes a third mounting portion 4022, which is used to be installed on the vehicle body 1. The connecting end 411 of the driving arm 41 is rotatably connected to the third mounting portion 4022. The setting of the third mounting portion 4022 can ensure the connection stability between the driving arm 41 and the vehicle body 1, thereby ensuring the stability of the driving arm 41 driving the second door 3 to rotate around the second end 4112 as the axis.

[0177] The vehicle further comprises a second drive device 5, see Fig.24 , Fig.25 and Fig.26 The second driving device 5 is arranged at the door sill position of the vehicle body 1. The second driving device 5 includes a guide member 51, a connecting member 52 and a driver 53. The guide member 51 is connected to the vehicle body 1; the connecting member 52 is connected to the guide member 51, and the connecting member 52 is rotatably connected to the supporting member 55; the driver 53 is connected to the connecting member 52, and can drive the connecting member 52 to move along the target moving direction O.

[0178] In some embodiments, the driver 53 is an electric push rod.

[0179] In some embodiments, the guide member 51 is a guide rail, and the connecting member 52 can be slidably connected to the guide rail and guided along the target moving direction O by the guide member 51.

[0180] In the above embodiment, a guide member 51 is provided to guide the connecting member 52 along the target moving direction O, so as to reduce the possibility of the connecting member 52 deviating from the predetermined trajectory when moving along the target moving direction O, thereby reducing the possibility of the connecting member 52 getting stuck during the movement, making the movement of the second drive device 5 and the support member 55 smoother, and the opening and closing of the second door 3 also smoother, reducing the possibility of the second door 3 getting stuck during the opening and closing process, and improving the reliability of the vehicle.

[0181] In some embodiments, see Fig.24 , Fig.25 and Fig.26 The driver 53 includes a transmission part 531 and a driving part 532. The transmission part 531 is passed through the connecting member 52, and the guide member 51 can limit the rotation of the connecting member 52; the driving part 532 is connected to one end of the transmission part 531, and the driving part 532 can rotate the transmission part 531 to drive the connecting member 52 to move along the target moving direction O.

[0182] In some embodiments, the transmission part 531 is a screw with external threads, the driving part 532 is a motor capable of rotating the screw, and the connecting member 52 is a nut with internal threads and sleeved on the screw. When the transmission part 531 as a screw drives the connecting member 52 as a nut to move, it can withstand a large axial load, output a large force, and obtain better movement stability.

[0183] In some embodiments, the guide member 51 assembled with the connecting member 52 can limit the rotation of the connecting member 52 to prevent the connecting member 52 from rotating with the transmission part 531, so that the connecting member 52 can rotate relative to the transmission part 531, and then can be driven by the transmission part 531 to move along the target moving direction O.

[0184] In the above embodiment, the rotatable transmission part 531 is provided to drive the connecting member 52 to move along the target moving direction O, so that the second driving device 5 can output a larger torque when driving the second door 3 to rotate through the supporting member 55, and can adapt to the door opening method with higher torque requirements. At the same time, the second door 3 can also be opened and closed more smoothly.

[0185] In some embodiments, see Fig.23 and Fig.24 The connecting member 52 has a limiting groove 521 along one side perpendicular to the target moving direction O; the second driving device 5 also includes a limiter 56, which is connected to the guide member 51, and the limiter 56 can enter the limiting groove 521 along a direction perpendicular to the target moving direction O.

[0186] Specifically, when the stopper 56 enters the limit groove 521, the stopper 56 can abut against the groove wall of the limit groove 521 along the target moving direction O, and limit the connecting member 52 along the target moving direction O, so that the second door 3 can be suspended during the rotation process. When the driving part 532 continues to work or the second door 3 is driven by a large external force, the stopper 56 will move out of the limit groove 521 to allow the second door 3 to continue to rotate.

[0187] In the above embodiment, the stopper 56 is provided so that the second door 3 can be stopped after the rotation stops.

[0188] In some embodiments, the second driving device 5 includes a plurality of limiters 56 , and the plurality of limiters 56 are arranged at intervals along the target moving direction O.

[0189] In some embodiments, the second driving device also includes a second sensor, which is arranged on the driver 53 and is used to sense the rotation angle of the second hinge device 12. Before the second sensor senses that the second hinge device 12 rotates to the second angle β, it limits the second hinge device 12 from rotating in the direction of the first angle α.

[0190] In this embodiment, the second sensor may be a Hall sensor. In other embodiments, the second sensor may also be an angle detector. In this embodiment, the first sensor and the second sensor may be used in combination to replace the limiter 56 in the above embodiment. That is, without using the limiter 56, the rotation angle of the second hinge device 12 can be controlled by the first sensor and the second sensor. Therefore, when opening the second door 3, the second hinge device 12 can first rotate the first angle α and then rotate the second angle β to open the second door 3. When closing the second door 3, the second hinge device 12 can first rotate the second angle β and then rotate the first angle α to close the second door 3.

[0191] See also Fig.21 , the first sensor and the second sensor are used to replace the limiter 56 in the above embodiment, the driving member 42 is the first motor, and the driver 53 is the second motor. By increasing the damping of the first motor and the second motor, the transmission rod 43 and the sliding member 44 are controlled respectively, and the activities of the transmission part 531 and the driving part 532 are controlled to achieve the same effect as the limiter 56. For example, when the second door 3 is opened, before or during the second hinge device 12 rotates by the first angle α, the transmission rod 43 and the sliding member 44 are fixed by increasing the damping force of the first motor, so that the transmission The rod 43 and the sliding member 44 can limit the second hinge device 12 from rotating in the β direction. When the second hinge device 12 rotates to the first angle α, the damping of the first motor is reduced through the first sensor and a signal is sent to the second sensor. After the second sensor receives the signal, the transmission part 531 and the driving part 532 are controlled by the second motor to be fixed, so that the transmission part 531 and the driving part 532 can limit the second hinge device 12 from continuing to rotate to the first angle α, thereby controlling the second hinge device 12 not to exceed the first angle α and the second angle β, thereby achieving the limiting effect.

[0192] Correspondingly, when closing the second door 3, the transmission part 531 and the driving part 532 are controlled to be fixed by increasing the damping of the second motor, thereby limiting the second hinge device 12 from rotating to the first angle α. At this time, the first motor controls the transmission rod 43 and the sliding member 44 to rotate the second hinge device 12 to the second angle β. When the second hinge device 12 rotates to the second angle β, the first motor that controls the transmission rod 43 and the sliding member 44 increases the damping, so that the transmission rod 43 and the sliding member 44 are fixed, so that the second hinge device 12 rotates to the first angle α under the drive of the transmission part 531 and the driving part 532 until it rotates to the first angle α, and the second door 3 is closed.

[0193] In some embodiments, the limiter 56 and the second sensor can be used simultaneously to make the second hinge device 12 rotate the first angle α first and then the second angle β to open the second door 3, or make the second hinge device 12 rotate the second angle β first and then the first angle α to close the second door 3.

[0194] In some embodiments, a plurality of limiters 56 arranged at intervals along the target moving direction O can respectively limit the connection member 52 along the target moving direction O and form a plurality of limit points, wherein the plurality of limit points at least include a first limit point. When the second door 3 is closed, the connection member 52 is located at the first limit point to reduce the probability of accidental opening of the second door 3 when the second door 3 is closed. Fig.25 The connecting member 52 is located at the first limit point.

[0195] In some embodiments, the plurality of limit points further include a second limit point. When the second door 3 is opened to the maximum angle, the connecting member 52 is located at the second limit point to reduce the probability of the second door 3 being accidentally closed when the second door 3 is opened to the maximum angle. Fig. 27 The connecting member 52 is located at the second limit point.

[0196] In some embodiments, the plurality of limit points further include a third limit point, and the third limit point is located between the first limit point and the second limit point along the target moving direction O. When the second door 3 is located between the position opened to the maximum angle and the closed position, the connecting member 52 is located at the third limit point, so that the second door 3 remains suspended in the middle of opening, thereby reducing the possibility of accidental further opening or accidental further closing of the second door 3. Fig.26 The connecting member 52 is located at the third limit point.

[0197] In the above embodiment, a plurality of limiters 56 are provided to limit the second door 3 when it is located at different angles, so that the use of the second door 3 is more convenient and the use comfort of the vehicle is improved.

[0198] In some embodiments, see Fig.24 The limiter 56 includes an elastic portion 561 and a third limiting portion 562, one end of the elastic portion 561 is connected to the guide member 51; the third limiting portion 562 is connected to the other end of the elastic portion 561, and at least a portion of the third limiting portion 562 can enter the limiting groove 521 along a direction perpendicular to the target moving direction O.

[0199] In some embodiments, the elastic member is used to ensure that at least a portion of the third limiting portion 562 is located within the limiting groove 521, and when the connecting member 52 squeezes the third limiting portion 562 open, it generates elastic deformation in a direction perpendicular to the target moving direction O to send a portion of the limiter 56 into the limiting groove 521.

[0200] In some embodiments, the stopper 56 has a guide surface so that after being connected to the connecting member 52 along the target moving direction O, the stopper 56 can move in a direction perpendicular to the target moving direction O in a direction away from the connecting member 52 .

[0201] Specifically, when the third limiting portion 562 is located in the limiting groove 521 and contacts the groove wall of the limiting groove 521 along the target moving direction O, if the force applied by the connecting member 52 to the third limiting portion 562 along the target moving direction O forms a component force in a direction perpendicular to the target moving direction O that is greater than the force applied by the elastic portion 561 to the third limiting portion 562, then the limiting of the connecting member 52 by the limiter 56 is released, the connecting member 52 can continue to move along the target moving direction O, and the second door 3 continues to rotate; if the force applied by the connecting member 52 to the third limiting portion 562 along the target moving direction O forms a component force in a direction perpendicular to the target moving direction O that is less than or equal to the force applied by the elastic portion 561 to the third limiting portion 562, then the limiter 56 limits the connecting member 52, the connecting member 52 cannot move along the target moving direction O, and the second door 3 remains suspended.

[0202] In the above embodiment, the elastic portion 561 is provided so that the third limiting portion 562 can move in a direction perpendicular to the target moving direction O in a direction away from the connecting member 52 after contacting the connecting member 52, thereby releasing the limiting of the connecting member 52, and also allowing the third limiting portion 562 to enter the limiting groove 521 to achieve the limiting of the connecting member 52.

[0203] In some embodiments, see Fig.23 and Fig.24 The guide member 51 has a guide groove 551 on one side facing the support member 55, and the guide groove 551 extends along the target moving direction O. The connecting member 52 is arranged in the guide groove 551, and the limit groove 521 is connected with the guide groove 551; the guide member 51 also has an installation through hole 552, which is connected with the guide groove 551, and the limiter 56 is arranged in the installation through hole 552.

[0204] In some embodiments, the opening of the guide groove 551 is toward the vehicle support plane along the height direction Z.

[0205] In some embodiments, the elastic portion 561 passes through the mounting through hole 552 , and the third limiting portion 562 is disposed in the mounting through hole 552 .

[0206] In some embodiments, the mounting through hole 552 is a through hole that passes through the guide member 51 in a direction perpendicular to the target moving direction O. The limiter 56 also includes a mounting portion that is embedded in the through hole. The end of the elastic portion 561 away from the third limiting portion 562 is connected to the mounting portion to be indirectly connected to the guide member 51.

[0207] In the above embodiment, by setting the mounting through hole 552 to allow part of the limiter 56 to pass through the guide member 51, so as to reduce the influence of the limiter 56 on the size of the second drive device 5, the outer size of the second drive device 5 can be smaller, thereby reducing the space occupied by the second drive device 5.

[0208] In some embodiments, see Fig.24 The guide groove 551 has a first groove wall 5511 , the first groove wall 5511 is located on a side of the connecting member 52 away from the supporting member 55 , and the mounting through hole 552 is provided on the first groove wall 5511 .

[0209] Specifically, when the limiter 56 limits the connection member 52 , it is located at a side of the connection member 52 away from the vehicle support plane.

[0210] In the above embodiment, the limiter 56 connected to the first groove wall 5511 can further reduce the size of the second drive device 5 in the width direction of the vehicle body 1, so that the size of the door sill 103 along the width direction of the vehicle body 1 can be larger, thereby making the strength of the vehicle body 1 better and the performance of the vehicle better. In this embodiment, the width direction is the third direction Y.

[0211] In some embodiments, see Fig.25 , Fig.26 and Fig. 27 The driver 53 is disposed in the guide groove 551 , and the driver 53 is connected to the guide member 51 .

[0212] In the above embodiment, the guide member 51 of the driver 53 also serves as the housing of the second driving device 5, which can make the second driving device 5 more compact and facilitate the transportation of the second driving device 5. At the same time, when the second driving device 5 is installed on the second door 3, it is only necessary to connect the guide member 51 to the second door 3 to realize the connection between the second driving device 5 and the second door 3, thereby reducing the difficulty of vehicle assembly.

[0213] In some embodiments, the second door 3 can rotate relative to the vehicle body 1 around the rotation axis 33; the support member 55 includes a first connection end 553 and a second connection end 554 arranged at intervals, the first connection end 553 is rotationally connected to the second driving device 5, and the second connection end 554 is rotationally connected to the door sill 103; along the width direction of the vehicle body 1, the straight line where the rotation axis 33 is located has a first orthographic projection 331 on the longitudinal symmetry plane of the vehicle body 1; the first connection end 553 has a fourth orthographic projection 5531 on the longitudinal symmetry plane of the vehicle, and the second connection end 554 has a fifth orthographic projection 5541 on the symmetry plane of the vehicle, and the fourth orthographic projection 5531 is located on the side of the fifth orthographic projection 5541 away from the first orthographic projection 331. In this embodiment, the height direction of the vehicle body is the second direction Z.

[0214] Specifically, the connecting member 52 has a first position and a second position. During the process of the second door 3 rotating from closed to open, the connecting member 52 moves along the target moving direction O close to the straight line where the rotating shaft 33 is located to move from the first position to the second position. Fig.25the second door 3 from the opening to the closing process, the connecting member 52 along the target moving direction O away from the straight line where the rotation axis 33 moves from the second position to the first position, Fig. 27 The connecting member 52 is located in the second position.

[0215] In the above embodiment, the second connection end 554 of the support member 55 is closer to the side where the body 1 is connected to the second door 3 in the length direction of the body 1. In this embodiment, the length direction is the first direction X, and when the second door 3 is opened, the first connection end 553 of the support member 55 is closer to the side where the second door 3 is connected to the hinge, so that the support member 55 is closer to the connection between the body 1 and the second door 3, thereby reducing the possibility of collision between the support member 55 and people entering or exiting the vehicle when the second door 3 is opened, thereby improving the comfort of use of the vehicle.

[0216] See also Figure 1 In some embodiments, the vehicle further includes a first locking component 011 and a second locking component 012, and the first locking component 011 and the second locking component 012 are both arranged at the first door 2 and the vehicle body 1, and are used to lock the first door 2, wherein the first locking component 011 is located at a position where the first door 2 and the vehicle body 1 are close to the vehicle chassis and close to the second door 3, and the second locking component 012 is located at a position where the first door 2 and the vehicle body 1 are away from the vehicle chassis and close to the second door 3, and is used to lock the first door 2 at a position close to the second door 3.

[0217] In this embodiment, the first locking component 011 and the second locking component 012 have the same structure but different positions. The first door 2 can be locked more securely by using two locking components, and the first locking component 011 and the second locking component 012 are respectively arranged at positions close to and away from the vehicle chassis, so that both ends of the side of the front door away from the first hinge device can be locked, thereby further improving the locking security of the first door 2.

[0218] The first locking component 011 may be a lock buckle and a lock nose, wherein one of the lock buckle and the lock nose is arranged on the first door 2 and the other is arranged on the vehicle body 1. In other embodiments, the first locking component 011 may also be a magnetic attraction device.

[0219] In some embodiments, the vehicle further includes a third locking component 13 and a fourth locking component 14, both of which are arranged on the second door 3 and the vehicle body 1 for locking the second door 3, wherein the third locking component 13 is located at a position where the second door 3 and the vehicle body 1 are close to the vehicle chassis and close to the first door 2, and the fourth locking component 14 is located at a position where the second door 3 and the vehicle body 1 are away from the vehicle chassis and close to the first door 2, and is used to lock the second door 3 at a position close to the first door 2.

[0220] In this embodiment, the third locking component 13 and the fourth locking component 14 have the same structure but different positions. The second door 3 uses two locking components to lock the second door 3 more securely, and the third locking component 13 and the fourth locking component 14 are respectively arranged at positions close to and away from the vehicle chassis, so that both ends of the first door 2 away from the third mounting end can be locked, thereby further improving the secureness of the locking of the second door 3.

[0221] The third locking component 13 , the fourth locking component 14 and the first locking component 011 , the second locking component 012 have the same structure.

[0222] In some embodiments, the vehicle further includes an electronic lock disposed on the second door 3 and the vehicle body, wherein the electronic lock is located on a side of the second body away from the load-bearing portion, and is used to lock the second door 3 at a position away from the first door 2 .

[0223] In this embodiment, the electronic lock can be used to further lock the second door 3, thereby improving the stability of the second door 3 after closing.

[0224] In some embodiments, the vehicle also includes: a first sealing strip 15, which is arranged on the side of the first door 2 facing the second door 3; and a second sealing strip 16, which is arranged on the side of the second door 3 facing the first door 2, and when the first door 2 and the second door 3 are in a closed state, the first sealing strip 15 is arranged close to the outside relative to the second sealing strip 16; the second hinge device 12 is configured to guide the second sealing strip 16 to move with the second door 3 in a direction away from the body 1 and the first door 2 to avoid the first sealing strip 15.

[0225] In this embodiment, when the first door 2 and the second door 3 are in the closed state, the first sealing strip 15 and the second sealing strip 16 ensure the sealing between the first door 2 and the second door 3, and can prevent the first door 2 and the second door 3 from directly contacting and generating friction, thereby causing damage to the first door interior panel 17, the first door sheet metal 18, and the second door sheet metal 19. In the process of opening the second door 3, the second sealing strip 16 can be guided by the second hinge device 12 to move with the second door 3 away from the vehicle body 1 and the first door 2, so as to avoid the first sealing strip 15 and the second sealing strip 16.

[0226] In some embodiments, seats are also provided in the vehicle, among which the main driver seat and the co-driver seat are swivel seats. The setting of the swivel seats enables the main driver seat and the co-driver seat to rotate the seats when the vehicle is not moving, so as to communicate more conveniently with the passengers in the back seats.

[0227] In the prior art, in a car with double doors, the motion envelopes of the front and rear doors overlap, which makes it easy for the front and rear doors to interfere with each other during opening and closing. However, in the vehicle provided in this embodiment, when it is necessary to open the door, the second door 3 can move in a direction away from the first door 2 under the guidance of an external force by using the second hinge device 12, thereby eliminating the interference between the first door 2 and the second door 3, and then moving the first door 2 in a direction away from the vehicle body 1. Closing the rear door 202 is the opposite of the above process, which will not be repeated here.

[0228] When the first door 2 and the second door 3 are both closed, since the motion envelopes of the first door 2 and the second door 3 overlap, if the door is opened directly in a direction away from the vehicle body 1, the first sealing strip 15 and the second sealing strip 16 will also interfere with each other. However, in the automobile provided in this embodiment, when the second door 3 is opened alone, the first sealing strip 15 provided on the first door 2 is unsealed as the second door 3 moves away from the first door 2, and since the second door 3 moves in a direction away from the first door 2, the first sealing strip 15 will not interfere with the opening of the second door 3, and similarly, the second sealing strip 16 will not interfere with the opening of the front door.

[0229] It should be noted that in the process of opening the second door 3 alone, the second door 3 avoids the first door 2, so that the motion envelope of the second door 3 does not overlap with the motion envelope of the first door 2. This makes it possible for the first door 2 to be opened or closed at will in the process of opening the rear door alone. Similarly, in the process of closing the second door 3 alone, the first door 2 can also be opened or closed at will.

[0230] The technical solution provided in the embodiments of the present application is described below in conjunction with specific embodiments.

[0231] Embodiment 1:

[0232] The vehicle includes a body 1 and a first door 2 and a second door 3, wherein the first door 2 and the second door 3 are arranged on the body 1 to form a double-door; the body 1 is provided with a first hinge device 11 and a second hinge device 12, the body 1 and the first door 2 are rotationally connected via the first hinge device 11, and the body 1 and the second door 3 are rotationally connected via the second hinge device 12; during the opening process of the second door 3, the second door 3 can be opened outwardly via the second hinge device 12 in a direction away from the first door 2 to escape the interference of the first door 2; during the closing process of the second door 3, the second door 3 can be closed inwardly via the second hinge device 12 in a direction close to the first door 2 to escape the interference of the first door 2.

[0233] The double-doors make it easier for passengers to get on and off the vehicle, and the second door 3 can be opened outwardly away from the first door 2 via the second hinge device 12, so that when the second door 3 is opened, it will not interfere with the first door 2, so that the second door 3 can be opened alone, which is more convenient. When the second door is closed, the second door 3 can be closed inwardly toward the first door 2 via the second hinge device 12, and it will not interfere with the first door 2, so that the second door 3 can be closed alone, which is more convenient.

[0234] Embodiment 2:

[0235] The first hinge device 11 includes: a first mounting component 111, a pin shaft 112 and a second mounting component 113, the pin shaft 112 extends along the third direction Z, the first mounting component 111 is rotatably connected to the second mounting component 113 through the pin shaft 112, the first mounting component 111 is installed on the vehicle body 1, and the first mounting component 111 is fixedly connected to the vehicle body 1, the second mounting component 113 is installed on the first door 2, and the second mounting component 113 is fixedly connected to the first door 2.

[0236] The dimension of the first mounting component 111 in the first direction X is L1 mm, and the dimension of the first mounting component 111 in the third 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 component 111 in the third direction Z to the dimension L1 mm of the first mounting component 111 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.

[0237] When the value of L2 / L1 is less than 0.7, the overall structure of the first mounting assembly 111 is smaller and the overall structural strength is lower, and the connection between the vehicle body 1 and the first door 2 cannot be effectively achieved; when the value of L2 / L1 is greater than 0.889, the overall structure of the first mounting assembly 111 is larger, and more space is occupied, which affects the structural size and strength of other components.

[0238] The ratio of the dimension L2 mm of the first mounting component 111 in the third direction Z to the dimension L1 mm of the first mounting component 111 in the first direction X is controlled within the range of 0.7 to 0.889, so that the overall structural size of the first mounting component 111 is reasonably designed and the structural size of the first mounting component 111 is optimized, thereby effectively improving the structural strength and rigidity of the first mounting component 111, ensuring the overall structural stability of the first hinge device 11, and ensuring that the first door 2 is free of abnormalities during use, so as to meet the door use conditions of a car without a B-pillar design.

The connection between the rotating arm assembly 122 and the fourth mounting assembly 123 has a second rotating axis O2, and the rotating arm assembly 122 and the fourth mounting assembly 123 can rotate relative to each other around the second rotating axis O2. In this way, the second hinge device 12 of this embodiment constrains the motion trajectory of the second door 3 through the first rotating axis O1 and the second rotating axis O2, so that the second door 3 can achieve a specific compound motion during the opening and closing process, and can reduce the risk of the second door 3 interfering with other structures during the opening and closing process. In particular, for the case where the vehicle adopts a double-door design without a B-pillar, the second hinge device 12 of this embodiment can reduce the risk of the second door 3 interfering with other doors (such as the first door 2 mentioned above).
