Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a hinge assembly and a vehicle. Background Technology

[0002] To enable the opening and closing of the vehicle's tailgate, the tailgate needs to be connected to the vehicle body via a hinge assembly, allowing the tailgate to rotate relative to the vehicle body. Specifically, the hinge assembly is configured in two sets, connected to opposite sides of the tailgate along the Y-axis of the vehicle. The distance between the mounting bracket on the hinge assembly that connects to the tailgate and the side edge of the tailgate cannot be too large in order to increase the strength of the tailgate edge area and prevent deformation of the edge area. As a result, the current hinge assembly limits the width of the tailgate, which in turn restricts the further expansion of the vehicle's luggage compartment. Utility Model Content

[0047] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0050] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0051] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0052] like Figure 1As shown, in order to open and close flexibly, the tailgate 1 needs to be connected to the vehicle body via a hinge assembly. The hinge assembly can be a gooseneck hinge assembly 2, the main structure of which includes a curved gooseneck section. One end of the gooseneck section is connected to the vehicle body via a hinge seat and can rotate relative to the vehicle body. The other end is fixedly connected to the tailgate via a connecting seat 3, so that the tailgate can rotate relative to the vehicle body together with the gooseneck section. In order to achieve force balance, the gooseneck hinge assembly 2 is set into two sets. The two sets of gooseneck hinge assemblies 2 are connected to opposite sides of the tailgate along the Y direction of the vehicle. The distance W between the connecting seat 3 on the gooseneck hinge assembly 2 and the side edge of the tailgate 1 cannot be too large. That is, the connecting seat 3 needs to be close to the edge of the tailgate 1 to avoid deformation of the edge area (the middle area of ​​the tailgate 1 has a relatively complex structure due to its many design features, so it has sufficient strength and does not need to be supported by the connecting seat 3). Therefore, in related technologies, the width of the tailgate is actually constrained by the distance between the two connecting seats 3. Based on this, if it is necessary to expand the trunk, the trunk opening will also be expanded accordingly, and the width of the tailgate will also need to be increased accordingly. However, the connection position between the hinge assembly and the body is relatively fixed, making it difficult to increase the distance between the two hinge assemblies (i.e., between the connecting seats 3) by adjusting the connection position with the body. This restricts the width of the tailgate 1, which in turn affects the expansion of the trunk. Alternatively, when the trunk expands and the width of the tailgate 1 increases, the distance W between the connecting seat 3 and the side edge of the tailgate 1 increases, resulting in lower strength in the edge area of ​​the tailgate 1, making it more prone to deformation.

[0053] Based on the above problems, this utility model proposes a hinge assembly that can accommodate a wider tailgate, thereby facilitating the expansion of the luggage compartment. For ease of understanding, the directions in this utility model are first defined as follows: The directions of up, down, front, back, left, and right involved in this utility model refer to the vehicle's orientation in the O-XYZ coordinate system. The origin O coincides with the vehicle's center of mass. "Front end" refers to the X-direction parallel to the ground pointing forward; "rear end" refers to the X-direction parallel to the ground pointing backward; "left side" refers to the Y-direction parallel to the ground pointing to the driver's left; "right side" refers to the Y-direction parallel to the ground pointing to the driver's right; "upper end" refers to the Z-direction passing through point O pointing upward; "lower end" refers to the Z-direction passing through point O pointing downward. The XZ plane is a vertical plane parallel to the X-direction.

[0054] Reference Figures 2 to 4 The first embodiment of this utility model proposes a hinge assembly 10, including a hinge body 400, a first mounting base 100 and a second mounting base 200. The hinge body 400 includes a main body portion 410, at least a portion of which is bent in the X direction of the vehicle to form an arc-shaped structure. The opening of the arc-shaped structure faces outwards and the arched portion faces inwards, thereby increasing the opening angle of the tailgate.

[0055] The first mounting base 100 is connected to one end of the hinge body 400, for example... Figure 4 At the lower end, the second mounting base 200 is connected to the opposite end of the hinge body 400, for example... Figure 4 The upper part of the first mounting base 100 is used to connect with the tailgate of the vehicle, and is provided with a corresponding connection structure. For example, the connection structure is a connection hole, and fasteners can be fixedly connected to the tailgate through the connection hole. The second mounting base 200 is used to connect with the body of the vehicle, and is provided with a corresponding connection structure. For example, the connection structure is a connection hole, and fasteners can be fixedly connected to the body through the connection hole.

[0056] In addition, the hinge body 400 can also rotate relative to the second mounting base 200. Specifically, the hinge body 400 is connected to the second mounting base 200 through a pivot, so that the tailgate can rotate synchronously with the hinge body 400 relative to the second mounting base 200, thereby realizing the opening and closing of the tailgate.

[0057] Reference Figure 4 , Figure 5 The first mounting base 100 includes a first connecting portion 110 for connecting to the tailgate. For example, the first connecting portion 110 is provided with at least one mounting hole for connecting to the tailgate. Figures 2 to 4 As shown, the first mounting base 100 has two mounting holes, which are distributed along the length of the first connecting portion 110. In this embodiment, the first connecting portion 110 is offset outward in the Y direction of the vehicle relative to the main body 410 of the hinge body 400. This increases the distance between the two first connecting portions 110, allowing for a wider tailgate while ensuring sufficient strength in the tailgate edge area. This facilitates the installation of a larger luggage compartment and increases its storage capacity. It should be noted that the offset of one component relative to another can mean that the centerline of one component is offset from the centerline of another component. Figure 4 As shown in the example, viewed from behind the vehicle, Figure 4 The image shows the hinge assembly 10 located on the left side of the tailgate. Therefore, the offset of the first connecting portion 110 relative to the main body 410 in the Y-direction of the vehicle specifically means that the centerline of the first connecting portion 110 is offset to the left by a distance L1 relative to the centerline of the main body 410. Similarly, for the hinge assembly 10 located on the right side of the tailgate, the offset of the first connecting portion 110 relative to the main body 410 in the Y-direction of the vehicle specifically means that the centerline of the first connecting portion 110 is offset to the right relative to the centerline of the main body 410. The offset L1 of the first connecting portions 110 on both sides can be the same, thus increasing the distance between the two first connecting portions 110 by a factor of 2 L1.

[0058] It should be noted that in some specific embodiments, the offset of the first connecting portion 110 is relatively small, such as... Figure 4 As shown, the first connecting part 110 and the main body part 410 are not completely offset in the Y direction. When the overall size of the first mounting base 100 is small, the small offset can prevent the first mounting base 100 from undergoing large deformation, which is convenient for processing. In some other specific embodiments, the offset of the first connecting part 110 is relatively large. For example, the first connecting part 110 and the main body part 410 are completely offset in the Y direction, so as to accommodate a wider tailgate.

[0059] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figures 3 to 5 The first mounting base 100 also includes a first transition portion 120, through which the first connecting portion 110 is connected to the main body portion 410. The first transition portion 120 is configured to tilt or bend outwards in the Y-direction of the vehicle, thus making the transition between the first connecting portion 110 and the main body portion 410 smoother. Furthermore, compared to the naturally curved main body portion 410, the first transition portion 120 in the first mounting base 100 is easier to process, thereby reducing the processing difficulty of the hinge body 400. Figure 4 As shown, the first transition portion 120 is configured to be inclined outward in the Y direction of the vehicle, and a rounded corner is formed between the first transition portion 120 and the first connecting portion 110.

[0060] In some further embodiments, the first connecting part 110 and the first transition part 120 are connected as an integral structure, and the first transition part 120 and the hinge body 400 are fixed by welding, fastener connection or other means.

[0061] In some further embodiments, reference is made to Figure 4 Both the main body 410 and the first connecting part 110 are parallel to the XZ plane of the vehicle. That is, the projections of the main body 410 and the first connecting part 110 onto the horizontal plane extend along the X direction of the vehicle. This simplifies the structure of the first connecting part 110 and the main body 410. For example, the main body 410 only needs to be bent in the XZ plane and does not need to be bent in the Y direction, thus facilitating the processing of the main body 410. The same applies to the first connecting part 110. Furthermore, it also facilitates the connection between the first connecting part 110 and the tailgate. Figure 4 As shown, the first connecting part 110 is generally a strip structure extending in a straight line.

[0062] Based on the first embodiment, in some other embodiments of the present invention, the hinge body 400 further includes a third connecting portion and a third transition portion. The third connecting portion is connected to one end of the main body 410 via the third transition portion, and the third connecting portion is connected to the first mounting base 100. For example, the third connecting portion is connected to the lower end of the main body 410 via the third transition portion, thereby forming the lower end of the entire hinge body 400 (the third connecting portion and the third transition portion can be understood with reference to the fourth connecting portion 420 and the fourth transition portion 430 below). In this embodiment, the third transition portion is configured to tilt or bend outward in the Y direction of the vehicle, that is, in Figure 4 In the illustrated embodiment, a transition portion for offsetting the first connecting portion 110 of the first mounting base 100 is provided on the first mounting base 100, while in this embodiment, the transition portion for offsetting the first connecting portion 110 is provided on the hinge body 400.

[0063] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figure 2 , Figure 4 The second mounting base 200 includes a second connecting portion 210 for connecting to the vehicle body. In this embodiment, the second connecting portion 210 is offset inward relative to the main body portion 410 in the Y direction of the vehicle. This further increases the distance between the two first connecting portions 110, allowing for a wider tailgate while ensuring sufficient strength in the tailgate edge area. On the other hand, it can be seen that the main body portion 410 of the hinge body 400 avoids the outer side of the vehicle in the Y direction. Combined with a corresponding avoidance design for the trim panel inside the trunk, the usable space in the trunk can be increased. Figure 4 As shown in the example, viewed from behind the vehicle, Figure 4 The image shows the hinge assembly 10 located on the left side of the tailgate. Therefore, the inward offset of the second connecting portion 210 relative to the main body 410 in the Y-direction of the vehicle specifically means that the centerline of the second connecting portion 210 is offset to the right by a distance L2 relative to the centerline of the main body 410. Similarly, for the hinge assembly 10 located on the right side of the tailgate, the inward offset of the second connecting portion 210 relative to the main body 410 in the Y-direction of the vehicle specifically means that the centerline of the second connecting portion 210 is offset to the left relative to the centerline of the main body 410. Since the offset L2 of the second connecting portions 210 on both sides can be the same, the distance between the first connecting portions 110 on both sides increases by the sum of twice the offset L1 and twice the offset L2.

[0064] For example, as shown in Figure 4, the second connecting portion 210 includes two wing plates 211 located on opposite sides of the hinge body 400. Each wing plate 211 is provided with multiple mounting holes, and the mounting holes on both sides may be the same or different. The second mounting base 200 also includes a mounting protrusion 212 located between the two wing plates 211. The mounting protrusion 212 defines an insertion cavity. The end of the hinge body 400 is inserted into the insertion cavity and is rotatably connected to the mounting protrusion 212 via a pivot. Based on this, the offset of the second connecting portion 210 relative to the main body 410 in the vehicle Y direction specifically means that the centerline of the mounting protrusion 212 is offset relative to the main body 410 in the vehicle Y direction.

[0065] When the second connecting portion 210 is offset inward relative to the main body portion 410 in the Y direction of the vehicle, in some embodiments of the present invention, referring to Figure 4 , Figure 5 The hinge body 400 also includes a fourth connecting portion 420 and a fourth transition portion 430. The fourth connecting portion 420 is connected to the other end of the main body 410 via the fourth transition portion 430, and the fourth connecting portion 420 is connected to the second mounting base 200. For example, the fourth connecting portion 420 is connected to the upper end of the main body 410 via the fourth transition portion 430, thus forming the upper end of the entire hinge body 400. In this embodiment, the fourth transition portion 430 is configured to tilt or bend inwards towards the vehicle's Y-direction, thereby making the transition between the second connecting portion 210 and the main body 410 smoother. Figure 4 As shown, the fourth transition portion 430 is inclined inward toward the Y direction of the vehicle, and a rounded corner is formed between the fourth transition portion 430 and the fourth connecting portion 420.

[0066] In some further embodiments, reference is made to Figure 4 Both the main body 410 and the fourth connecting part 420 are parallel to the XZ plane of the vehicle. That is, the projections of the main body 410 and the fourth connecting part 420 onto the horizontal plane extend along the X direction of the vehicle. This simplifies the structure of the fourth connecting part 420 and the main body 410. For example, the main body 410 only needs to be bent within the XZ plane, not in the Y direction, thus facilitating its machining. The same applies to the fourth connecting part 420. Furthermore, it facilitates the connection between the fourth connecting part 420 and the second mounting base 200. Figure 4 As shown, the fourth connecting part 420 is generally a strip structure extending in a straight line.

[0067] Based on the first embodiment, in some other embodiments of the present invention, the second mounting base 200 further includes a second transition portion, and the second connecting portion 210 is connected to the main body portion 410 through the second transition portion. The second transition portion is configured to tilt or bend outward in the Y direction of the vehicle. Specifically, the third transition portion is configured to tilt or bend outward in the Y direction of the vehicle, that is, in... Figure 4 In the illustrated embodiment, the transition portion for offsetting the second connecting portion 210 is provided on the hinge body 400, while in this embodiment, the transition portion for offsetting the second connecting portion 210 is provided on the second mounting base 200.

[0068] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figures 2 to 4 The hinge assembly 10 also includes a third mounting base 300, a support rod 500, and an elastic element 600. The support rod 500 and the elastic element 600 provide auxiliary power during tailgate opening and damping during tailgate closing, reducing the user's effort. The support rod 500 can be a hydraulic rod or a gas spring, and the elastic element 600 can be a tension spring. In this embodiment, both the support rod 500 and the elastic element 600 are connected to the third mounting base 300. Compared to a scheme where they are connected through separate mounting bases, this reduces the number of mounting bases and lowers the weight of the hinge assembly 10.

[0069] The third mounting base 300 is connected to the hinge body 400. For example, the third mounting base 300 is located at the upper end of the hinge body 400 and is fixed to the hinge body 400 by welding or other means. The third mounting base 300 includes a first section and a second section. One end of the first section is connected to the hinge body 400 and the other end is connected to the second section. The second section is used to connect the support rod 500 and the elastic element 600. The first section extends approximately along the Y direction and the second section is approximately parallel to the XZ plane.

[0070] Reference Figure 5The third mounting base 300 has a fifth connecting portion 310 and a sixth connecting portion 320. A support rod 500 is connected to the fifth connecting portion 310, and an elastic element 600 is connected to the sixth connecting portion 320. The fifth connecting portion 310 and the sixth connecting portion 320 are located in different positions, which satisfies the requirement of connecting the support rod 500 and the elastic element 600 to the same mounting base while preventing interference between them. The fifth connecting portion 310 and the sixth connecting portion 320 can be mounting holes. The support rod 500 and the elastic element 600 can be connected to the third mounting base 300 directly or indirectly. For example, the hinge assembly 10 also includes a ball joint structure. One end of the ball joint structure has a mounting post connected to the third mounting base 300 via the fifth connecting portion 310, and the other end of the ball joint connects to a spherical groove on the support rod 500, thereby allowing the support rod 500 to rotate upwards relative to the third mounting base 300.

[0071] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figures 4 to 6 The hinge assembly 10 also includes a third mounting base 300, a plastic bushing 700 and an elastic element 600. The third mounting base 300 is connected to the hinge body 400. The third mounting base 300 and the elastic element 600 can be understood with reference to the aforementioned embodiments.

[0072] In this embodiment, the plastic bushing 700 is connected to the third mounting base 300. For example, when the third mounting base 300 is provided with the aforementioned sixth connecting portion 320, the plastic bushing 700 is connected to the sixth connecting portion 320. Correspondingly, the elastic member 600 includes an elastic portion 610 and a hook portion 620 connected to the elastic portion 610. Specifically, the elastic portion 610 provides elasticity, and the hook portion 620 is located at the end of the elastic portion 610, passing through the plastic bushing 700 and capable of rotating relative to the plastic bushing 700, thereby adapting to the angle change between the hinge body 400 and the elastic member 600 during the opening of the tailgate. In this embodiment, fixing the elastic member 600 with the plastic bushing 700 can significantly reduce the noise generated during the relative rotation of the elastic member 600 and the hinge body 400.

[0073] When the hinge assembly 10 also includes a plastic bushing 700, refer to Figure 7 The sixth connecting portion 320 of the third mounting base 300 includes a mounting hole 301, which can be a circular hole for ease of machining. (See reference...) Figure 8 The plastic bushing 700 includes a cylindrical body 710, which passes through the mounting hole 301, and a hook portion 620 passes through the cylindrical body 710 to achieve the connection between the elastic element 600 and the plastic bushing 700.

[0074] Furthermore, to prevent the plastic bushing 700 from rotating relative to the third mounting base 300, the sixth connecting portion 320 also includes a limiting hole 302. The plastic bushing 700 also includes a limiting portion 720 connected to the outer periphery of the cylinder 710. The limiting portion 720 passes through the limiting hole 302 to restrict the rotation of the plastic bushing 700 relative to the third mounting base 300. There can be multiple limiting holes 302, which are evenly distributed along the circumference of the mounting hole 301 to provide multiple limiting points. Correspondingly, there can also be multiple limiting portions 720. In addition, in this embodiment, the limiting hole 302 communicates with the mounting hole 301, and the limiting portion 720 is connected to the cylinder 710 as an integral structure. Therefore, the plastic bushing 700 can be formed by injection molding on the third mounting base 300.
