Description

Technical Field

[0001] This utility model relates to the field of hinge connection technology, specifically to a hinge structure and a vehicle. Background Technology

[0002] The hinge structure in the related technology includes a fixed part and a movable part. The fixed part has a fixed portion, and the movable part has a movable portion. A pivot passes through the fixed portion and the movable portion to allow the fixed portion and the movable portion to rotate relative to each other. The fixed portion has a limiting groove, and the movable portion has a limiting protrusion. The limiting protrusion is inserted into the limiting groove to limit the rotation angle of the fixed part and the movable part. However, the limiting protrusion is subjected to large forces and is prone to deformation. The limiting effect of the wire is poor, and the appearance is not neat, making it easy for impurities to enter and affect the rotation. Utility Model Content

[0003] One objective of this utility model is to provide a hinge structure to solve the problems in the prior art where the limiting protrusion is easily deformed, resulting in poor limiting effect and an uneven appearance that affects rotation; the second objective is to provide a vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A hinge structure includes: a first hinge member, including a plug portion having a first rotating hole, and first limiting protrusions at both axial ends of the plug portion; a second hinge member, including a limiting portion located on both axial sides of the plug portion, the limiting portion having a second rotating hole, and a second limiting protrusion on the side of the limiting portion facing the plug portion, the second limiting protrusion forming an abutment surface, the first limiting protrusion being adapted to abut against the abutment surface; and a pivot inserted into the first rotating hole and the second rotating hole, the first hinge member being rotatable relative to the second hinge member around the pivot, and the orthographic projection of the first limiting protrusion being located within the orthographic projection of the limiting portion on a plane perpendicular to the pivot.

[0006] According to the above-mentioned technical means, by placing the insertion part between the two limiting parts and using a rotating shaft inserted into the first rotating hole and the second rotating hole, the relative position between the first hinge member and the second hinge member can be limited, allowing them to rotate relative to each other. The relative position between the first and second hinge members is limited by the abutting surfaces of the first and second limiting protrusions. Furthermore, since the limiting protrusions are located at both axial ends of the insertion part, and the limiting parts are located on both axial sides of the insertion part, with the two first limiting protrusions respectively engaging with the two second limiting protrusions, the insertion part can be limited at both axial ends. This helps reduce the force on each first limiting protrusion, lowers the probability of deformation under stress, and improves the accuracy of limiting the first and second hinge members. In addition, on a plane perpendicular to the axis of rotation, the orthographic projection of the first limiting protrusion is located within the orthographic projection of the limiting part. That is to say, when the hinge structure is observed from one end of the axis of rotation, the first limiting protrusion is blocked by the limiting part and cannot be observed. The appearance of the hinge structure is neater, and the mating part between the insertion part and the limiting part is less likely to get dust and other impurities, which is conducive to improving the smoothness of the relative rotation between the first hinge and the second hinge.

[0007] Furthermore, the second limiting protrusion includes: a central portion connected to the limiting portion; and an abutting portion connected to the limiting portion, wherein the abutting portion is connected to the outer peripheral surface of the central portion, and the abutting portion is provided with the abutting surface along one circumferential side of the central portion.

[0008] According to the above technical means, by dividing the second limiting protrusion into a central part and an abutment part, the structural strength of the second limiting protrusion can be improved, the probability of damage to the second limiting protrusion can be reduced, and it is also beneficial to cover the first limiting protrusion. The appearance of the hinge structure is neater, and the mating part between the insertion part and the limiting part is less likely to get dust and other impurities, which is beneficial to improving the smoothness of the relative rotation between the first hinge and the second hinge.

[0009] Furthermore, the outer peripheral surface of the central portion is spaced apart from the first limiting protrusion.

[0010] According to the above-mentioned technical means, when the first hinge and the second hinge rotate relative to each other, the first limiting protrusion will not rub against the center, reducing noise and scratches, and improving the smoothness of the movement of the first hinge.

[0011] Furthermore, the second hinge also includes a mounting portion, which is connected to the limiting portion; the abutment portion includes a first abutment portion and a second abutment portion, which are arranged and connected along the circumference of the center portion. The first abutment portion and the mounting portion are located on opposite sides of the center portion in the x-direction, and the second abutment portion and the mounting portion are located on opposite sides of the center portion in the y-direction. The x-direction and the y-direction intersect and are both perpendicular to the pivot.

[0012] According to the above-mentioned technical means, the first abutting part and the second abutting part can block the first limiting protrusion from the x direction and the y direction, reducing the probability that the part of the second limiting protrusion and the first limiting protrusion mating is observed, and improving the appearance.

[0013] Furthermore, the wall thickness of the central part is D, where 3mm ≤ D ≤ 6mm.

[0014] The above-mentioned technical means can prevent the limiting part from cracking under stress, and also reduce material costs and weight.

[0015] Furthermore, the contact area between the first limiting protrusion and the contact surface has a first dimension L along the axial direction of the rotating shaft, and the contact area between the first limiting protrusion and the contact surface has a second dimension W along the radial direction of the rotating shaft, where 5mm≤L≤8mm and 2mm≤W≤4mm.

[0016] According to the above technical means, the contact area between the first limiting protrusion and the abutment surface is sufficient. After multiple collisions and abutments, the abutment surface can still effectively limit the first limiting protrusion, thereby improving the positioning reliability between the first hinge and the second hinge, and reducing the area of ​​the abutment surface, thereby reducing the weight and material cost of the second hinge.

[0017] Furthermore, the first hinge also includes: a mounting plate; a connecting plate connected to the mounting plate at a preset angle, the plug-in portion being connected to the connecting plate, and the plug-in portion and the mounting plate being located on opposite sides of the thickness direction of the connecting plate.

[0018] According to the above-mentioned technical means, the insertion part can be exposed between the door, body and trim, which is conducive to the connection between the first hinge and the second hinge. On the other hand, during the rotation of the door, the hinge structure is less likely to interfere with the door, body and trim, thus improving the smoothness of the door rotation.

[0019] Furthermore, the first hinge member also includes a reinforcing rib, which is connected to the mounting plate and the connecting plate.

[0020] The above-mentioned technical means are beneficial to improving the structural strength between the mounting plate and the connecting plate, and reducing the probability of damage to the first hinge component.

[0021] A vehicle includes a body, a door, and the aforementioned hinge structure, wherein one of the first hinge and the second hinge is connected to the body, and the other is connected to the door.

[0022] Furthermore, the vehicle also includes a trim cover connected to the vehicle body, the trim cover including a first trim panel and a second trim panel, the first trim panel being located on the side of the hinge structure facing away from the vehicle body, the second trim panel being connected to the first trim panel, and the second trim panel being located at the top of the hinge structure.

[0023] The above-mentioned technical means can reduce the exposed area of ​​the hinge structure connected to the vehicle body, improve the appearance, prevent dust and water from entering the hinge structure, extend the service life of the hinge structure, and reduce the probability of damage to the hinge structure.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0048] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0049] The following is combined Figures 1 to 16 The following describes embodiments of the present invention.

[0050] This utility model embodiment proposes a hinge structure 1, which includes a first hinge member 100, a second hinge member 200, and a rotating shaft 300.

[0051] The first hinge member 100 includes a plug portion 110 with a first rotating hole 111 and first limiting protrusions 112 at both axial ends. The second hinge member 200 includes a limiting portion 210 located on both axial sides of the plug portion 110. The limiting portion 210 has a second rotating hole 211 and a second limiting protrusion 212 on the side of the limiting portion 210 facing the plug portion 110. The second limiting protrusion 212 forms an abutment surface 217, and the first limiting protrusion 112 is adapted to abut against the abutment surface 217. A rotating shaft 300 is inserted into the first rotating hole 111 and the second rotating hole 211, and the first hinge member 100 is rotatable relative to the second hinge member 200 around the rotating shaft 300. On a plane perpendicular to the rotating shaft 300, the orthographic projection of the first limiting protrusion 112 is located within the orthographic projection of the limiting portion 210.

[0052] The hinge structure 1 can be applied to two relatively rotating components. For example, when applied to vehicle 5, the hinge structure 1 enables the opening and closing of the tailgate of vehicle 5. Specifically, as shown... Figures 1-4 As shown, vehicle 5 includes body 3, door 2, and the aforementioned hinge structure 1. One of the first hinge member 100 and the second hinge member 200 is connected to body 3, and the other of the first hinge member 100 and the second hinge member 200 is connected to door 2. The rotation angle of the second hinge member 200 around the pivot 300 is approximately 136°.

[0053] By placing the insertion part 110 between the two limiting parts 210 and inserting the rotating shaft 300 into the first rotating hole 111 and the second rotating hole 211, the relative position between the first hinge member 100 and the second hinge member 200 can be limited, and the first hinge member 100 and the second hinge member 200 can rotate relative to each other.

[0054] For example, the outer circumferential surface of the rotating shaft 300 is provided with a spline, and the first hinge member 100 has a structure that mates with the spline in the first rotating hole 111 to fix the relative position between the rotating shaft 300 and the first hinge member 100 in the circumferential direction of the rotating shaft 300. Alternatively, the second hinge member 200 has a structure that mates with the spline in the second rotating hole 211 to fix the relative position between the rotating shaft 300 and the second hinge member 200 in the circumferential direction of the rotating shaft 300. That is, one of the first hinge member 100 and the second hinge member 200 is fixed in relative position with the rotating shaft 300 in the circumferential direction of the rotating shaft 300, while the other can rotate relative to the rotating shaft 300 in the circumferential direction of the rotating shaft 300.

[0055] When the first hinge 100 and the second hinge 200 rotate relative to each other, the relative position between the first hinge 100 and the second hinge 200 is limited by the first limiting protrusion 112 abutting against the abutment surface 217. Furthermore, since the first limiting protrusion 112 is located at both axial ends of the insertion portion 110, and the limiting portion 210 is provided on both axial sides of the insertion portion 110, with the two first limiting protrusions 112 abutting against the two abutment surfaces 217 respectively, the insertion portion 110 can be limited at both axial ends. This helps reduce the force on each first limiting protrusion 112, lowers the probability of deformation of the first limiting protrusion 112 under force, and improves the accuracy of limiting the first hinge 100 and the second hinge 200.

[0056] Furthermore, on a plane perpendicular to the pivot 300, the orthographic projection of the first limiting protrusion 112 lies within the orthographic projection of the limiting portion 210. In other words, when viewing the hinge structure 1 from one end along the axial direction of the pivot 300, the first limiting protrusion 112 is obscured by the limiting portion 210, making it invisible. This results in a more unified appearance for the hinge structure 1, and the mating portion of the first hinge member 100 and the second hinge member 200 is less prone to dust and other impurities, thus improving the smoothness of relative rotation between the first hinge member 100 and the second hinge member 200.

[0057] Furthermore, such as Figure 8 and Figure 12 As shown, the second limiting protrusion 212 includes a central portion 213 and an abutting portion 214. The central portion 213 is connected to the limiting portion 210. The abutting portion 214 is connected to the limiting portion 210 and is connected to the outer peripheral surface of the central portion 213. The abutting portion 214 has an abutting surface 217 along one circumferential side of the central portion 213.

[0058] By dividing the second limiting protrusion 212 into a central portion 213 and an abutment portion 214, the structural strength of the second limiting protrusion 212 can be improved, the probability of damage to the second limiting protrusion 212 can be reduced, and it is also beneficial to cover the first limiting protrusion 112. The appearance of the hinge structure 1 is neater, and the mating part between the insertion portion 110 and the limiting portion 210 is less likely to get dust and other impurities, which is beneficial to improving the smoothness of relative rotation between the first hinge member 100 and the second hinge member 200.

[0059] Furthermore, such as Figure 8 and Figure 12 As shown, the outer peripheral surface of the central portion 213 is spaced apart from the first limiting protrusion 112. In this way, when the first hinge member 100 and the second hinge member 200 rotate relative to each other, the first limiting protrusion 112 will not rub against the central portion 213, reducing noise and scratches, and improving the smoothness of the movement of the first hinge member 100.

[0060] In some embodiments, such as Figure 8 and Figure 12 As shown, the second hinge member 200 also includes a mounting portion 220, which is connected to the limiting portion 210. The abutment portion 214 includes a first abutment portion 215 and a second abutment portion 216. The first abutment portion 215 and the second abutment portion 216 are arranged and connected along the circumference of the center portion 213. The first abutment portion 215 and the mounting portion 220 are located on opposite sides of the center portion 213 in the x-direction, and the second abutment portion 216 and the mounting portion 220 are located on opposite sides of the center portion 213 in the y-direction. The x-direction and y-direction intersect and are both perpendicular to the rotation axis 300.

[0061] The x and y directions can be set perpendicularly. When the hinge structure 1 is applied to the vehicle 5, the axis of the rotating shaft 300 is the vertical direction of the vehicle 5, the x direction is the front-back direction of the vehicle, and the y direction is the left-right direction of the vehicle.

[0062] In this way, the first abutting part 215 and the second abutting part 216 can block the first limiting protrusion 112 from the x and y directions, reducing the probability that the mating part of the second limiting protrusion 212 and the first limiting protrusion 112 will be observed, and improving the appearance.

[0063] Furthermore, such as Figure 8 As shown, the wall thickness of the central part 213 is D, where 3mm ≤ D ≤ 6mm. D can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, or 6mm.

[0064] If D is less than 3mm, the wall thickness of the central part 213 is too small, resulting in low structural strength and a tendency to crack under stress. If D is greater than 6mm, the wall thickness of the central part 213 is too large, which increases the material cost and weight of the second hinge 200. On the other hand, it will cause the gap between the first limiting protrusion 112 and the mounting part 220 to be too small, increasing the probability of interference between the first limiting protrusion 112 and the mounting part 220.

[0065] By setting D to be greater than or equal to 3mm and less than or equal to 6mm, the wall thickness of the central part 213 is moderate, which can ensure structural strength, prevent the central part 213 from cracking under stress, reduce material costs and weight, and the gap between the first limiting protrusion 112 and the mounting part 220 can meet the requirements, reducing the probability of interference between the first limiting protrusion 112 and the mounting part 220, and ensuring the smooth rotation of the first hinge 100.

[0066] In some embodiments, such as Figure 10 and Figure 12 As shown, the contact area between the first limiting protrusion 112 and the contact surface has a first dimension L along the axial direction of the second rotating hole 211, and a second dimension W along the radial direction of the second rotating hole 211, where 5mm ≤ L ≤ 8mm and 2mm ≤ W ≤ 4mm. Specifically, L can be 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, and W can be 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.

[0067] When the first hinge 100 rotates to its limit position, the contact area between the first limiting protrusion 112 and the abutment surface is not less than 8mm. 2In this way, the contact area between the first limiting protrusion 112 and the abutment surface 217 is sufficient. After multiple collisions and abutments, the abutment surface 217 can still effectively limit the first limiting protrusion 112, thereby improving the positioning reliability between the first hinge member 100 and the second hinge member 200. Furthermore, the contact area between the first limiting protrusion 112 and the abutment surface 217 is no greater than 30 mm. 2 This reduces the area of ​​the contact surface 217, thereby reducing the weight and material cost of the second hinge 200. The second hinge 200 also occupies less space, which helps to reduce the gap between the door 2 and the body 3.

[0068] In some embodiments, the yield strength of the first hinge 100 is greater than or equal to 720 MPa, or the yield strength of the second hinge 200 is greater than or equal to 720 MPa, or both the yield strength of the first hinge 100 and the yield strength of the second hinge 200 are greater than or equal to 720 MPa. The first hinge 100 and the second hinge 200 may be made of 42CrMn material.

[0069] In this way, the first hinge member 100 and the second hinge member 200 have high yield strength. After the first limiting protrusion 112 and the abutment surface 217 collide and abut repeatedly, the first limiting protrusion 112 and the abutment surface 217 are not easily deformed, which can extend the service life of the hinge structure 1 and improve the working reliability of the hinge structure 1.

[0070] In some embodiments, such as Figure 13 and Figure 14 As shown, the first hinge member 100 also includes a mounting plate 120 and a connecting plate 130. The connecting plate 130 is connected to the mounting plate 120 at a preset angle. The plug-in part 110 is connected to the connecting plate 130. The plug-in part 110 and the mounting plate 120 are located on opposite sides of the thickness direction of the connecting plate 130.

[0071] Specifically, along the axial direction of the pivot 300, the dimensions of the mounting plate 120 and the connecting plate 130 are both larger than the dimensions of the insertion part 110. This results in a larger connection area between the mounting plate 120 and the door 2, and greater structural strength of the connecting plate 130, which helps improve the installation stability between the first hinge 100 and the door 2.

[0072] For example, the first hinge 100 is installed on the door 2. The door 2 includes a door body and a cover edge. The door body is connected to the cover edge and the mounting plate 120. The cover edge and the mounting plate 120 are located on the same side of the door body. The door body and the mounting plate 120 can be connected by bolts. The cover edge covers the mounting plate 120 and the connecting plate 130. The connecting plate 130 and the cover edge are arranged approximately parallel to each other, and the mounting plate 120 and the connecting plate 130 are arranged perpendicularly to each other. In this way, the reliability of the connection between the mounting plate 120 and the door 2 can be improved, and the mounting plate 120 and the connecting plate 130 are not easily observed by the outside world because they are covered by the cover edge, which helps to improve the appearance of the vehicle 5.

[0073] In this way, the insertion part 110 can be exposed between the door 2 and the body 3, which is beneficial to the connection between the first hinge 100 and the second hinge 200. On the other hand, during the rotation of the door 2, the hinge structure 1 is less likely to interfere with the door 2, the body 3 and the trim 4, thus improving the smoothness of the door 2 rotation.

[0074] Furthermore, such as Figure 13 As shown, the first hinge 100 also includes a reinforcing rib 140, which is connected to the mounting plate 120 and the connecting plate 130 to improve the structural strength of the mounting plate 120 and the connecting plate 130 and reduce the probability of damage to the first hinge 100.

[0075] In some embodiments, such as Figure 1 and Figure 2 As shown, the vehicle 5 also includes a cover 4, which is connected to the body 3. The cover 4 includes a first trim panel 41 and a second trim panel 42. The first trim panel 41 is located on the side of the hinge structure 1 facing away from the body 3, and the second trim panel 42 is connected to the first trim panel 41 and is located at the top of the hinge structure 1.

[0076] By setting the cover 4, the exposed area of ​​the hinge structure 1 connected to the body 3 can be reduced, improving the appearance and making it less likely for dust and water to enter the hinge structure 1, thus extending the service life of the hinge structure 1 and reducing the probability of damage to the hinge structure 1.
