DETAILED DESCRIPTION

[0039] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0040] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0041] like Figures 1 to 20As shown, this embodiment proposes a hinge assembly for a vehicle tailgate, comprising: a female hinge structure 1, a male hinge structure 2 and a locking member 3. The female hinge structure 1 comprises a female hinge member 11 and a rotating member 12. The female hinge member 11 is provided with a rotating hole 101. The rotating member 12 is provided in the rotating hole 101 along the axial direction of the rotating hole 101 and can rotate in the rotating hole 101. The rotating member 12 is provided with a positioning structure 13. The male hinge structure 2 is detachably connected to the rotating member 12. The locking member 3 is connected to the female hinge member 11 and is located at the female hinge member 11. 1 and the rotating member 12, the locking member 3 has a locking position and an unlocking position that can be switched between each other; wherein, when the locking member 3 is in the locking position, the locking member 3 is connected to the positioning structure 13, the female hinge member 11 is combined with the rotating member 12, and the male hinge structure 2 can move independently relative to the female hinge member 11 and the rotating member 12, so as to be able to be disassembled relative to the female hinge structure 1; when the locking member 3 is in the unlocking position, the locking member 3 is separated from the positioning structure 13, and the male hinge structure 2 and the rotating member 12 can rotate synchronously around the axis of the rotating hole 101.

[0042] In this embodiment, since the locking member 3 has a lock position and an unlock position that can be switched between each other, when the locking member 3 is in the unlock position, the locking member 3 is separated from the positioning structure 13, and the male hinge structure 2 is coupled to the rotating member 12. This allows the male hinge structure 2 and the rotating member 12 to rotate synchronously relative to the female hinge member 11 about the axis of the rotating hole 101, thereby achieving the opening or closing function of the tailgate 6. When the locking member 3 is in the lock position, the locking member 3 is connected to the positioning structure 13 of the rotating member 12, thereby coupling the female hinge member 11 with the rotating member 12. At this time, the male hinge structure 2 can move independently relative to the female hinge member 11 and the rotating member 12, thereby enabling the male hinge structure 2 to be removed from the rotating member 12 and the female hinge member 11. Therefore, compared to the disassembly of a traditional hinge, this hinge assembly can be removed from the vehicle without disassembling the entire hinge assembly.

[0043] It should be understood that the female hinge structure 1 and the male hinge structure 2 are connected to the tailgate 6 or the cargo box of the vehicle in a one-to-one correspondence to achieve the installation and removal, opening and closing of the tailgate 6 of the vehicle cargo box.

[0044] In this embodiment, the female hinge structure 1 is connected to the tailgate 6, and the male hinge structure 2 is connected to the cargo box of the vehicle. Therefore, by disassembling the female hinge structure 1 and the male hinge structure 2, the tailgate 6 and the cargo box of the vehicle can be disassembled; and the female hinge structure 1 is rotated relative to the male hinge structure 2 to realize the rotation of the tailgate 6 relative to the cargo box of the vehicle.

[0045] For example, the vehicle is a pickup truck.

[0046] Combine Figure 2 、 Figure 4 、 Figure 8 and Figure 9 As shown, the positioning structure 13 includes a positioning groove 102, which is recessed in the side wall c of the rotating member 12. When the locking member 3 is in the locked position, the locking member 3 is engaged in the positioning groove 102; when the locking member 3 is in the unlocked position, the locking member 3 is located outside the positioning groove 102.

[0047] In this embodiment, the positioning groove 102 is provided on the side wall c of the rotating member 12, and the positioning groove 102 is communicated with the rotating hole 101, and the side wall c of the rotating member 12 is connected to the hole wall of the rotating hole 101. When the locking member 3 is in the locked position, the locking member 3 is engaged in the positioning groove 102, the female hinge member 11 is coupled with the rotating member 12, and the rotating member 12 cannot rotate or move relative to the female hinge member 11, thereby allowing the male hinge structure 2 to move independently relative to the rotating member 12, and the male hinge structure 2 can be disassembled relative to the rotating member 12, thereby realizing the disassembly of the male hinge structure 2 relative to the female hinge structure 1; when the locking member 3 is in the unlocked position, the locking member 3 is located outside the positioning groove 102, the male hinge structure 2 is coupled with the rotating member 12, so that the male hinge structure 2 and the rotating member 12 can synchronously rotate relative to the female hinge member 11 around the axis of the rotating hole 101, thereby realizing the rotation of the male hinge structure 2 relative to the female hinge structure 1.

[0048] Combine Figure 2 and Figure 4 As shown, the female hinge member 11 is provided with a receiving groove 103 . When the locking member 3 is located at the unlocking position, the locking member 3 is located in the receiving groove 103 .

[0049] In this embodiment, the receiving groove 103 is provided in the wall of the rotating hole 101 and communicates with the rotating hole 101. The receiving groove 103 is used to accommodate the locking member 3 when the locking member 3 is in the unlocked position, preventing the locking member 3 from protruding too far from the wall of the rotating hole 101, thereby preventing interference during the rotation of the rotating member 12 relative to the female hinge member 11 and affecting the normal rotation of the hinge assembly. When the locking member 3 is in the unlocked position, the locking member 3 is located within the receiving groove 103, allowing the rotating member 12 to rotate relative to the female hinge member 11. This allows the male hinge structure 2 and the rotating member 12 to rotate synchronously about the axis of the rotating hole 101 relative to the female hinge member 11, thereby achieving normal rotation of the hinge assembly.

[0050] It should be understood that when the locking member 3 switches from the locked position to the unlocked position, the portion of the locking member 3 located within the positioning groove 102 moves out of the positioning groove 102 and returns to the receiving groove 103, thereby preventing the rotation of the rotating member 12 within the rotating hole 101 from being interfered with by the locking member 3, thereby enabling free rotation. At this time, the male hinge structure 2 and the rotating member 12 can rotate synchronously about the axis of the rotating hole 101, ultimately achieving the opening or closing function of the tailgate 6. When the locking member 3 switches from the unlocked position to the locked position, the portion of the locking member 3 located within the receiving groove 103 moves out of the receiving groove 103 and returns to the positioning groove 102, thereby enabling the female hinge member 11 to engage with the rotating member 12. At this time, the male hinge structure 2 can move independently relative to the female hinge member 11 and the rotating member 12, thereby enabling the male hinge structure 2 to be removed relative to the rotating member 12 and the female hinge member 11, ultimately achieving the removal of the tailgate 6 from the vehicle.

[0051] Combine Figure 2 and Figure 4 As shown, the locking member 3 includes an elastic return member 31 and a tenon 32, and the elastic return member 31 is connected between the tenon 32 and the female hinge member 11; when the locking member 3 switches from the unlocking position to the locking position, the elastic return member 31 is in an elastic deformation state, and the tenon 32 is elastically engaged with the positioning groove 102.

[0052] In this embodiment, combined with Figure 2 as well as Figures 13 to 16 As shown, the tenon 32 is provided with a groove 301 for installing an elastic return member 31. The elastic return member 31 is connected between the groove wall of the groove 301 and the female hinge member 11. When the locking member 3 switches from the unlocking position to the locking position, the elastic return member 31 is in an elastic deformation state, so that the tenon 32 can move from the positioning groove 102 to the accommodating groove 103 through the elastic return member 31 to realize the opening or closing function of the hinge assembly.

[0053] Specifically, when the locking member 3 switches from the locking position to the unlocking position, the elastic return member 31 recovers from the elastic deformation state to the normal state, and the tenon 32 moves from the positioning groove 102 to the accommodating groove 103 through the restoring force of the elastic deformation, and when the elastic return member 31 is in the normal state, the tenon 32 can be maintained in the accommodating groove 103, avoiding the tenon 32 from protruding relative to the hole wall of the rotating hole 101, resulting in interference between the tenon 32 and the rotating member 12 during the rotation of the rotating member 12 relative to the female hinge member 11.

[0054] It should be understood that when the locking member 3 is in the locked position, the female hinge member 11 is driven to rotate relative to the rotating member 12 by rotating the tailgate 6, so that the tenon 32 can move from the positioning groove 102 to the accommodating groove 103, and the locking member 3 is switched from the locked position to the unlocked position, thereby realizing the opening function of the tailgate 6.

[0055] Further, combined with Figures 2 to 4 as well as Figure 8 As shown, the female hinge member 11 is provided with an operating hole 104 communicating with the rotating hole 101 , and the hinge assembly further comprises an unlocking member 4 , which can drive the locking member 3 to switch from the unlocking position to the locking position through the operating hole 104 .

[0056] In this embodiment, the unlocking member 4 includes an operating portion 41 and an unlocking portion 42 connected to the operating portion 41. The operating portion 41 is an arc-shaped structure to facilitate the installer to operate the unlocking portion 42, so that the unlocking portion 42 is penetrated by an operating hole 104 to drive the locking member 3 to switch from the unlocking position to the locking position, that is, the tenon 32 moves from the accommodating groove 103 to the positioning groove 102.

[0057] Furthermore, after the tenon 32 is engaged in the positioning groove 102, the rotating part 12 is combined with the female hinge part 11, making it almost impossible for the rotating part 12 to rotate relative to the female hinge part 11, thereby facilitating the disassembly of the male hinge structure 2 relative to the rotating part 12, and finally realizing the disassembly of the hinge assembly.

[0058] It should be understood that the operating hole 104 not only needs to be connected to the rotating hole 101, but also needs to be connected to the accommodating groove 103, so that the tenon 32 can be driven by the unlocking part 42 to move from the accommodating groove 103 to the positioning groove 102 to lock the rotating part 12 and the female hinge part 11.

[0059] Combine Figure 8 As shown, the female hinge part 11 includes a female hinge fixing part 111 and a female hinge guide part 112 connected to the female hinge fixing part 111, the female hinge fixing part 111 is provided with a rotating hole 101, the female hinge guide part 112 is located on one side of the female hinge fixing part 111 along the axial direction of the rotating hole 101, and a mounting hole 106 coaxial with the rotating hole 101 is provided in the female hinge guide part 112, the mounting hole 106 is connected to the rotating hole 101, and the diameter of the mounting hole 106 is larger than the diameter of the rotating hole 101.

[0060] In this embodiment, the female hinge fixing portion 111 is provided with two first fixing holes 105. The two first fixing holes 105 are spaced apart from the rotating hole 101 and are respectively located on two opposite sides of the rotating hole 101. The female hinge fixing portion 111 is connected to the tailgate 6 by two bolts passing through the two first fixing holes 105 respectively.

[0061] Combine Figure 8 and Figure 10 As shown, the male hinge structure 2 includes a male hinge fixing portion 21 and a male hinge mounting portion 22 connected to the male hinge fixing portion 21 . The male hinge mounting portion 22 is installed in the mounting hole 106 and can rotate along the hole wall of the mounting hole 106 relative to the female hinge guide portion 112 .

[0062] In this embodiment, the male hinge fixing portion 21 is provided with two second fixing holes 201, which are respectively located on two opposite sides of the male hinge mounting portion 22, and the male hinge fixing portion 21 is connected to the cargo box of the vehicle by two bolts passing through the two second fixing holes 201 respectively.

[0063] In addition, the female hinge guide portion 112 is provided with a mounting hole 106 coaxial with the rotating hole 101, and after the male hinge mounting portion 22 is installed in the mounting hole 106, the male hinge mounting portion 22 can be rotated along the hole wall of the mounting hole 106 relative to the female hinge guide portion 112, and then the female hinge guide portion 112 provides a certain guiding and limiting effect for the rotation of the male hinge mounting portion 22, which is beneficial to ensure the stability of the rotation between the female hinge structure 1 and the male hinge structure 2, and ultimately ensures the stability of the rotation of the tailgate 6 relative to the cargo box of the vehicle.

[0064] Combine Figures 7 to 9 and Figure 12 As shown, the male hinge mounting portion 22 is provided with a mounting groove 202; the rotating member 12 includes a rotating shaft 121 and a mounting protrusion 122 connected to the rotating shaft 121, the rotating shaft 121 is passed through the rotating hole 101, and is provided with a positioning structure 13, the radial length of the mounting protrusion 122 along the rotating shaft 121 is greater than the inner diameter of the rotating hole 101, the mounting protrusion 122 is located in the mounting hole 106, the mounting protrusion 122 is clamped in the mounting groove 202, and can move toward or away from the mounting groove 202 along the radial direction of the mounting hole 106 through the opening 203 of the mounting groove 202.

[0065] In this embodiment, the male hinge mounting portion 22 is connected to the mounting protrusion 122 through the mounting groove 202, that is, the male hinge mounting portion 22 is connected to the rotating shaft 121, so that the male hinge mounting portion 22 can rotate synchronously with the rotating shaft 121 relative to the female hinge fixing portion 111 to realize the opening and closing function of the tailgate 6.

[0066] It should be understood that the rotating shaft 121 and the mounting protrusion 122 are an integral structure, that is, the rotating shaft 121 and the mounting protrusion 122 rotate synchronously relative to the female hinge component 11 .

[0067] In this embodiment, combined with Figure 1 、 Figure 7 and Figure 12As shown, the mounting groove 202 is provided with an opening 203 for avoiding the mounting protrusion 122, so that the mounting protrusion 122 can move along the radial direction of the mounting hole 106 through the opening 203 of the mounting groove 202 toward the mounting groove 202, thereby realizing the connection between the mounting protrusion 122 and the male hinge mounting portion 22; the mounting protrusion 122 can move along the radial direction of the mounting hole 106 through the opening 203 of the mounting groove 202 toward away from the mounting groove 202, thereby realizing the separation of the mounting protrusion 122 and the male hinge mounting portion 22, thereby realizing the detachable connection between the female hinge structure 1 and the male hinge structure 2.

[0068] At the same time, the radial length of the mounting protrusion 122 along the rotating shaft 121 is greater than the inner diameter of the rotating hole 101, so that the mounting protrusion 122 can play a certain limiting role in the installation of the rotating shaft 121 in the female hinge fixing part 111, thereby preventing the rotating shaft 121 from passing through the rotating hole 101 from one end and then out from the other end, thereby affecting the installation of the hinge assembly.

[0069] It should be understood that since the mounting protrusion 122 is located in the mounting hole 106, and the male hinge mounting portion 22 engaged with the mounting protrusion 122 is also located in the mounting hole 106, the diameter of the mounting hole 106 should be greater than the radial length of the mounting protrusion 122 along the rotating shaft 121; at the same time, the radial length of the mounting protrusion 122 along the rotating shaft 121 is greater than the inner diameter of the rotating hole 101, therefore, the diameter of the mounting hole 106 should be greater than the diameter of the rotating hole 101.

[0070] In this embodiment, combined with Figure 1 、 Figures 7 to 10 As shown, the female hinge guide portion 112 is provided with an avoidance notch 107 along the radial direction of the mounting hole 106, and the avoidance notch 107 is connected to the mounting hole 106. The avoidance notch 107 enables the male hinge mounting portion 22 to enter the mounting hole 106 from outside the mounting hole 106 and connect with the mounting protrusion 122 to realize the installation of the female hinge structure 1 and the male hinge structure 2; at the same time, the male hinge mounting portion 22 can move from the mounting hole 106 to the outside of the mounting hole 106 through the avoidance notch 107 and separate from the mounting protrusion 122 to realize the disassembly of the female hinge structure 1 and the male hinge structure 2.

[0071] Combine Figure 2 、 Figure 7 and Figure 12 As shown, the groove wall of the mounting groove 202 has a disassembly wall a and a limiting wall b, and the disassembly wall a and the opening 203 of the mounting groove 202 are arranged correspondingly along the radial direction of the mounting hole 106; wherein, when the locking member 3 is in the locking position, the disassembly wall a is arranged corresponding to the avoidance notch 107, and can enable the male hinge mounting portion 22 to move to the outside of the mounting hole 106 through the avoidance notch 107.

[0072] In this embodiment, when the locking member 3 is in the locking position, the male hinge mounting portion 22 rotates to the disassembly wall a corresponding to the avoidance notch 107, that is, the opening 203 of the mounting groove 202 and the avoidance notch 107 are respectively located on two opposite sides of the disassembly wall a along the radial direction of the mounting hole 106. At this time, the male hinge mounting portion 22 can move from the inside of the mounting hole 106 to the outside of the mounting hole 106 through the avoidance notch 107 along the radial direction of the mounting hole 106. At the same time, the mounting protrusion 122 moves along the radial direction of the mounting hole 106 through the opening 203 of the mounting groove 202 toward away from the mounting groove 202, thereby separating the male hinge mounting portion 22 from the mounting protrusion 122 to realize the disassembly of the hinge assembly. In addition, the male hinge mounting portion 22 can move from the outside of the mounting hole 106 to the inside of the mounting hole 106 along the radial direction of the mounting hole 106 through the avoidance notch 107, and at the same time, the mounting protrusion 122 moves along the radial direction of the mounting hole 106 through the opening 203 of the mounting groove 202 toward the inside of the mounting groove 202, thereby connecting the male hinge mounting portion 22 to the mounting protrusion 122 to realize the installation of the hinge assembly.

[0073] It should be understood that, except for the disassembly wall a, the rest of the groove walls of the installation groove 202 are limiting walls b.

[0074] Combine Figure 7 As shown, the hinge assembly further includes a booster spring 5 , which is sleeved on the rotating shaft 121 , with one end of the booster spring 5 connected to the rotating shaft 121 , and the other end of the booster spring 5 connected to the female hinge fixing portion 111 .

[0075] In this embodiment, a first through-hole 108 is defined on the side wall c of the rotation shaft 121, spaced apart from the positioning slot 102. A second through-hole 109 is defined on the female hinge fixing portion 111, spaced apart from the operating hole 104 and the rotation hole 101. A booster spring 5 is sleeved around the rotation shaft 121, with one end of the booster spring 5 positioned within the first through-hole 108 and the other end within the second through-hole 109.

[0076] Specifically, when the locking member 3 is in the unlocked position, the male hinge structure 2 and the rotating member 12 can rotate synchronously around the axis of the rotating hole 101. Therefore, during the opening process of the tailgate 6, the female hinge fixing part 111 will rotate with the rotation of the tailgate 6. One end of the assist spring 5 is connected to the female hinge fixing part 111, so that the assist spring 5 will elastically deform due to the external force. The reverse resistance generated by the assist spring 5 can offset a certain amount of the gravity of the tailgate 6, so that the assist spring 5 plays a role of assisting in the process of opening the tailgate; during the closing process of the tailgate 6, the assist spring 5 will elastically deform due to the external force exerted on the tailgate when opening the tailgate, and will slowly return to its original state when the tailgate 6 is closed, so that the assist spring 5 plays a role of assisting in the process of closing the tailgate.

[0077] It should be understood that during the opening process of the tailgate 6, the gravitational potential energy of the tailgate 6 itself is converted into the elastic potential energy of the assisting spring 5, and the elastic deformation of the assisting spring 5 is cleverly used to convert energy, thereby achieving the effect of assisting without consuming external force.

[0078] In this embodiment, the female hinge structure 1 and the locking member 3 can be used or sold as one product after being matched; the male hinge structure 2 and the unlocking member 4 can both be used or sold as one product.

[0079] In summary, the installation method of the hinge assembly of the vehicle tailgate is as follows: first, one end of the elastic return member 31 is installed on the tenon 32 through the groove 301 of the tenon 32; secondly, the assembled elastic return member 31 and the tenon 32 are installed together to form an integral part in the positioning groove 102 of the rotating shaft 121; thirdly, the assembled elastic return member 31, the tenon 32, the rotating shaft 121 and the mounting protrusion 122 are passed through the female hinge guide portion 112 and the female hinge fixing portion 111 along the axial direction of the mounting hole 106 and the rotating hole 101 until the mounting protrusion 122 is in contact with the female hinge fixing portion 111. When the hinge 110 is in contact with the mounting hole 106, the mounting groove 202 is engaged with the mounting protrusion 122, and the elastic return member 31 is located between the groove 301 of the tenon 32 and the female hinge fixing portion 111. Then, the assist spring 5 is sleeved on the rotating shaft 121, one end of the assist spring 5 is located in the first through hole 108, and the other end of the assist spring 5 is located in the second through hole 109. Finally, the male hinge structure 2 is installed in the mounting hole 106 through the avoidance notch 107, so that the mounting groove 202 is engaged with the mounting protrusion 122, thereby completing the installation of the hinge assembly of the vehicle tailgate.

[0080] The vehicle tailgate hinge assembly is disassembled as follows: First, the unlocking member 4 is inserted into the female hinge fixing portion 111 through the operating hole 104. A certain force is applied to push the tenon 32 from the receiving groove 103 to the positioning groove 102, thereby switching the locking member 3 from the unlocked position to the locked position. The rotating shaft 121 and the mounting protrusion 122 cannot rotate relative to the female hinge guide portion 112 and the female hinge fixing portion 111. Then, the male hinge structure 2 is reversely withdrawn from the mounting hole 106 through the avoidance notch 107, thereby completing the disassembly function of the hinge assembly and facilitating the repair of the tailgate 6. After the tailgate 6 is repaired, the final step of the vehicle tailgate hinge assembly installation method is to install the male hinge structure 2 into the mounting hole 106 through the avoidance notch 107, so that the mounting groove 202 engages with the mounting protrusion 122, thereby facilitating the installation and removal of the tailgate 6, thereby facilitating the convenient removal and installation of the vehicle tailgate hinge assembly.

[0081] This embodiment also proposes a vehicle, including a tailgate 6, a cargo box and the hinge assembly of the above-mentioned vehicle tailgate, wherein the female hinge part 11 is connected to the tailgate 6, the rotating part 12 is located inside the tailgate 6, the male hinge structure 2 is connected to the cargo box, and the female hinge part 11 and the tailgate 6 rotate synchronously relative to the male hinge structure 2 and the cargo box around the axis of the rotating part 12.

[0082] In this embodiment, the hinge assembly of the vehicle tailgate is installed on the vehicle as follows: first, the integral component formed by the female hinge structure 1 and the locking member 3 is installed on the tailgate 6 through the first fixing hole 105 with bolts; then, the male hinge structure 2 is inserted into the mounting hole 106 through the avoidance gap 107 and connected to the mounting protrusion 122; finally, by moving the cargo box door, the male hinge structure 2 is installed on the vehicle cargo box through the second fixing hole 201 with bolts.

[0083] In this embodiment, combined with Figure 19 and Figure 20 As shown, the vehicle includes two hinge assemblies for the vehicle tailgate, and the two hinge assemblies are located on two opposite sides in the length direction of the tailgate 6 and are connected between the tailgate 6 and the cargo box of the vehicle; the axes of the rotating holes 101 of the two hinge assemblies are located on the same horizontal plane, and the tailgate 6 rotates around the axes of the rotating holes 101 of the two hinge assemblies to realize the opening and closing functions of the tailgate 6.
