[0028] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0029] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0030] In the related art, a vehicle includes a body, a tailgate, a hinge and a strut, wherein the body and the tailgate are connected by a hinge, and a partial structure of the hinge can move together with the tailgate, a first strut bracket is fixed to the body, a second strut bracket is fixed to the tailgate, one end of the strut is rotatably connected to the first strut bracket, and the other end of the strut is rotatably connected to the second strut bracket.

[0031] However, in the above-mentioned vehicle, when the vehicle is assembled and manufactured, the hinge and the first strut bracket need to be installed on the vehicle body respectively, which is not conducive to improving the assembly efficiency of the vehicle.

[0032] Therefore, in order to overcome this defect, the present embodiment provides a hinge assembly and a vehicle, wherein the hinge assembly integrates the hinge and the strut bracket together. When assembling the vehicle, it is only necessary to install the hinge assembly between the vehicle body roof and the rear door. Compared with the related art, one assembly link can be reduced, thereby improving the assembly efficiency of the vehicle.

[0033] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of the hinge assembly provided in the embodiment of the present application. Figure 2 An exploded view of the hinge assembly provided in an embodiment of the present application, Figure 3 A schematic diagram of a partial structure of a vehicle provided in an embodiment of the present application. As shown in the figure, the present embodiment provides a hinge assembly 10, including a hinge assembly 1 and a mounting bracket 2, wherein the hinge assembly 1 is used to be connected between the vehicle body roof 20 and the back door 30; the mounting bracket 2 is connected to the hinge assembly 1, and the mounting bracket 2 is used to be rotatably connected to one end of a support rod 40, and the other end of the support rod 40 is rotatably connected to the back door 30. When the support rod 40 is extended, it can drive the back door 30 to move upward so that the back door 30 is opened; when the support rod 40 is shortened, it can drive the back door 30 to move downward so that the back door 30 is closed.

[0035] Thus, when assembling a vehicle using the hinge assembly 10 provided in this embodiment, it is only necessary to install the hinge assembly 10 between the vehicle body roof 20 and the tailgate 30, whereas in the related art, the hinge and the first strut bracket need to be installed on the vehicle body separately. Therefore, compared with the related art, the present application can reduce one assembly link, thus improving the assembly efficiency of the vehicle.

[0036] In addition, compared with the solution using a hinge and a first strut bracket in the related art, the hinge assembly 10 provided in the present application omits the connection between the first strut bracket and the vehicle body. Therefore, it is not only possible to reduce the cost of using connecting parts during the assembly process, but also to reduce the labor cost during the assembly process.

[0037] It should be noted that, in this embodiment, the above-mentioned support rod 40 can be an electric support rod, or a support rod driven by a hydraulic method, etc. Here, the type of the support rod 40 is not specifically limited.

[0038] Specifically, the hinge assembly 1 includes a rotatably connected fixed portion 11 and a movable portion 12 ; the fixed portion 11 is used to connect with the vehicle body roof 20 , and the movable portion 12 is used to connect with the rear tailgate 30 , and the movable portion 12 can move together with the rear tailgate 30 .

[0039] The fixing portion 11 includes a fixing plate 111 and an adapter plate 112. The fixing plate 111 extends in the vertical direction. The thickness direction of the fixing plate 111 is consistent with the length direction of the vehicle. The fixing plate 111 is provided with a plurality of first connection holes 1111. The fixing plate 111 can be detachably connected to the vehicle body roof cover 20 by fasteners, such as screws or other threaded fasteners, which are passed through the plurality of first connection holes 1111. It should be noted that Figure 3 Only the outer panel of the vehicle body roof 20 is shown. In the vehicle, the vehicle body roof 20 may also have an inner panel and / or a reinforcing panel, and the above-mentioned fixing plate 111 should be connected to a part of the structure on the inner panel or the reinforcing panel through fasteners, and the part of the structure should also extend in the vertical direction.

[0040] The vertical direction mentioned above Figures 1 to 3 The direction of the central axis is consistent with the length of the vehicle. Figures 1 to 3 The xx-axis direction is consistent.

[0041] Furthermore, the adapter plate 112 is connected to the rear end surface of the fixed plate 111, the adapter plate 112 is perpendicular to the fixed plate 111, the thickness direction of the adapter plate 112 is consistent with the width direction of the vehicle, and the adapter plate 112 is rotatably connected to the movable part 12. Figures 1 to 3 The front and rear directions are shown in FIG. , and the width direction of the vehicle can be seen in FIG. Figure 3 The yy-axis direction in .

[0042] In order to facilitate the connection between the fixed plate 111 and the adapter plate 112, a positioning protrusion 1112 can be set on the top of the fixed plate 111, and the positioning protrusion 1112 can abut against the outer panel of the vehicle body roof cover 20. The setting of the positioning protrusion 1112 can not only determine the connection position between the fixed plate 111 and the adapter plate 112, but also strengthen the structural strength of the connection between the fixed plate 111 and the adapter plate 112, so as to improve the structural strength of the hinge assembly 10 provided in this embodiment.

[0043] In addition, the connection method between the fixed plate 111 and the adapter plate 112 can be welding. In order to improve the welding quality between the fixed plate 111 and the adapter plate 112, a notch 1121 can be formed on the side of the adapter plate 112 facing the fixed plate 111. The formation of the notch 1121 allows the welding arc to better penetrate into the junction between the fixed plate 111 and the adapter plate 112, ensuring that the weld can reach a sufficient penetration depth, thereby enhancing the strength of the weld.

[0044] Moreover, in this embodiment, the shape of the notch 1121 is close to a "V-shape". Such a design can make the weld more beautiful and is also conducive to the control of internal defects of the weld.

[0045] In addition, the design of notch 1121 can control the heat input during welding and avoid material deformation caused by excessive heat; in addition, the formation of notch 1121 can ensure that the welding tool or welding gun can reach the welding area, thereby achieving high-quality welding.

[0046] In order to achieve the connection between the movable part 12 and the rear tailgate 30 and enable the movable part 12 to move together with the rear tailgate 30, in some optional embodiments, the movable part 12 includes a avoidance plate 121 and a connecting plate 122 connected together, the avoidance plate 121 is rotatably connected to the fixed part 11, and the connecting plate 122 is used to connect to the rear tailgate 30.

[0047] Among them, two connecting ears 123 are set at one end of the avoidance plate 121 away from the connecting plate 122, and the two connecting ears 123 are arranged at intervals along the width direction of the vehicle. The adapter plate 112 is rotatably connected between the two connecting ears 123 through a rotating shaft 3, so that an axial hole 1122 is formed on the adapter plate 112.

[0048] It is understandable that if the movement angle of the tailgate 30 is to be ensured, it is necessary to overcome the interference problem between the tailgate 30 and the movable portion 12. Therefore, in some embodiments, a concave cavity 1211 with an upward opening can be formed on the avoidance plate 121. Through the setting of the concave cavity 1211, the tailgate 30 can be avoided during the opening process of the tailgate 30, so that the opening angle of the tailgate 30 is larger.

[0049] In order to strengthen the structural strength of the movable part 12 and further enhance the structural strength of the hinge assembly 1, a reinforcing protrusion 124 can be set on the front side of the avoidance plate 121. The setting of the reinforcing protrusion 124 can improve the structural strength of the movable part 12 and further enhance the structural strength of the hinge assembly 1.

[0050] It is understandable that if a detachable connection is adopted between the movable part 12 and the tailgate 30, the assembly efficiency between the hinge assembly 10 and the tailgate 30 can be improved. Therefore, in some optional embodiments, a plurality of second connecting holes 1221 can be provided on the connecting plate 122, and the connecting plate 122 and the tailgate 30 can be detachably connected together by fasteners such as screws passing through the second connecting holes 1221.

[0051] Since the size of fasteners such as screws is relatively fixed, if the thickness of the connecting plate 122 is large, it may not be able to adapt to the fastener. Therefore, in some specific embodiments, the thickness of the connecting plate 122 is less than the thickness of the avoidance plate 121. In this way, it can adapt to the length of the fastener and avoid interference problems caused by the large thickness of the avoidance plate 121 during the assembly process; in addition, the overall weight of the movable part 12 can be reduced, and then the overall weight of the hinge assembly 10 can be reduced, thereby facilitating the installation of the hinge assembly 10 between the vehicle body roof 20 and the tailgate 30.

[0052] In some embodiments, the mounting bracket 2 includes a bracket body 21 and a connecting portion 22 connected together; the bracket body 21 is fixedly connected to the hinge assembly 1, specifically, the bracket body 21 is connected to the edge of the fixed plate 111; the connecting portion 22 is used for rotationally connecting to the support rod 40.

[0053] Since the mounting bracket 2 is connected to the fixing plate 111, the mounting bracket 2 may also interfere with the opening process of the back door 30. To avoid this phenomenon, the bracket body 21 includes a first support portion 211 and a second support portion 212, wherein the second support portion 212 is connected to the rear side of the first support portion 211; the first support portion 211 is fixedly connected to the fixing plate 111, and the fixed connection here can be a welding connection mode, and the adapter portion 22 is arranged on the second support portion 212; wherein the top end of the first support portion 211 is higher than the top end of the second support portion 212, and the top end of the first support portion 211 is smoothly connected to the top end of the second support portion 212. In this way, an avoidance space can be formed above the second support portion 212 of the first support portion 211 to avoid the back door 30 during the opening process of the back door 30.

[0054] In some specific embodiments, the bracket body 21 is a support plate, and the adapter part 22 is connected to the end surface of the support plate; the adapter part 22 includes a connecting column 221 and a ball head structure 222, one end of the connecting column 221 is connected to the support plate, and the other end of the connecting column 221 is connected to the ball head structure 222, and the ball head structure 222 is used to be rotatably connected to the end of the support rod 40.

[0055] In some optional embodiments, in order to improve the structural strength of the mounting bracket 2, first flanges 23 are provided on both the upper and lower sides of the bracket body 21, and the first flanges 23 extend in a direction away from the bracket body 21. In this way, the first flanges 23 can disperse the stress acting on the bracket body 21 and reduce the stress concentration phenomenon. When the end of the support rod 40 is connected to the ball head structure 222, the bracket body 21 will be subjected to external force, and the first flanges 23 can share the stress more evenly to avoid damage caused by excessive local stress.

[0056] In this embodiment, in order to improve the structural strength of the connection between the mounting bracket 2 and the hinge assembly 1, a second flange 24 may be provided on the front side of the bracket body 21, the second flange 24 is connected to the fixing plate 111, and the second flange 24 is connected to the two first flanges 23. In this way, the structural strength of the mounting bracket 2 can be further enhanced, so as to further improve the structural strength of the hinge assembly 10 provided in this embodiment.

[0057] When the first flange 23 is provided, it may cause some interference to the connection between the support rod 40 and the adapter 22. Therefore, in order to overcome this phenomenon, in some embodiments, the first flange 23 has an escape end 231 close to the adapter 22, and there is a distance between the escape end 231 and the adapter 22, that is, the extension length of the first flange 23 is less than the side length of the bracket body 21 where it is located. In this way, a certain installation space can be provided for the connection between the support rod 40 and the adapter 22, which is convenient for installing the support rod 40, can improve the installation efficiency of the support rod 40, and further can improve the assembly and manufacturing efficiency of the vehicle as a whole.

[0058] This embodiment also provides a vehicle, including a vehicle body, a back door 30, a strut 40 and the above-mentioned hinge assembly 10, wherein the vehicle body includes a vehicle body roof 20; one end of the strut 40 is rotatably connected to the mounting bracket 2, and the other end of the strut 40 is rotatably connected to the back door 30. A strut bracket 50 may be provided on the back door 30, and the strut bracket 50 is rotatably connected to the other end of the strut 40. Here, the structure of the strut bracket 50 is not specifically limited.

[0059] It should be noted that the structure of the hinge assembly 10 has been described in detail in the above embodiments and will not be described in detail herein.

[0060] In the process of assembling the vehicle provided by the present embodiment, the hinge assembly 1 and the mounting bracket 2 are first welded together, and then the hinge assembly 1 is connected to the vehicle body roof 20 and the back door 30 respectively. After the hinge assembly 10 is installed, the strut 40 is installed, so that one end of the strut 40 is rotatably connected to the adapter 22, and the other end of the strut 40 is rotatably connected to the strut bracket 50. In this way, the installation of the hinge assembly 10 and the strut 40 is completed. Therefore, the assembly and manufacturing efficiency of the vehicle provided by the present embodiment is relatively high.

[0061] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto.
