[0005] Based on the hinge assembly of the embodiment of the present application, when the tailgate is connected to the vehicle body via the hinge assembly, there will be a gap between the tailgate and the vehicle body when the tailgate is in a closed state, and the shape of the hinge assembly will continuously change during the process of the tailgate being opened or closed relative to the vehicle body via the hinge assembly, and the hinge assembly with the changed shape drives the shielding member to move along the length direction of the vehicle body relative to the guide member; the specific process is: when the tailgate is in a closed state, the shielding member is in a first position, and the shielding member partially overlaps with the gap between the tailgate and the top cover of the vehicle body to cover the gap between the tailgate and the top cover of the vehicle body, and during the process of opening the tailgate, the shape of the hinge assembly changes, and drives the shielding member to move from the first position to the second position, so that the overlapping area between the shielding member and the gap between the tailgate and the top cover of the vehicle body gradually decreases, and the overlapping area between the shielding member and the guide member gradually increases to avoid the shape change of the hinge assembly.

[0006] In some embodiments of the present application, the guide member has a guide groove arranged along the length direction of the vehicle body; the shielding member is at least partially located in the guide groove and is slidably connected to the groove wall of the guide groove.

[0007] Based on the above embodiment, the guide member has a guide groove arranged along the length direction of the vehicle body, that is, the guide groove is provided in the guide member to limit the sliding direction of the shielding member to the length direction of the vehicle body.

[0009] Based on the above embodiments, the limiting portion in the limiting groove can not only realize the sliding connection between the shielding member and the guide member, but also the cooperation between the limiting portion and the limiting groove can prevent the shielding member and the guide member from being separated from each other.

[0010] In some embodiments of the present application, when the shielding member is in the second position, the shielding member and the guide member completely overlap along the height direction of the vehicle body.

[0011] Based on the above embodiment, when the shielding member is in the second position, the tailgate is in the maximum opening position. At this time, the length of the guide member can be reduced to make the vehicle body structure reasonable.

[0013] Based on the above embodiment, the tailgate is connected to the vehicle body via a connecting rod structure. When the tailgate rotates relative to the vehicle body, the shape of the connecting rod structure changes continuously. The connecting rod structure with continuously changing shape drives the first transmission member to move at least in the length direction of the vehicle body, and then drives the covering member to move along the length direction of the vehicle body through the first transmission member. The avoidance gap is used to accommodate one end of the first transmission member away from the connecting rod structure. When the first transmission member rotates relative to the covering member, the avoidance gap can prevent interference between the first transmission member and the covering member.

At this time, the first transmission member is connected to the position where the third connecting member moves the largest distance. The first transmission member has a sufficiently large moving distance, thereby allowing the shielding member to have a sufficiently large moving distance.

[0018] In some embodiments of the present application, the third connecting member includes a main body and a reinforcement portion, one end of the main body is rotatably connected to the second connecting member, and the other end is rotatably connected to the mounting seat and rotatably connected to the first transmission member; the reinforcement portion is protruding from the surface of the main body to strengthen the structure of the main body.

[0023] Based on the vehicle in the embodiment of the present application, since it has the above-mentioned hinge assembly, the hinge assembly can cover the gap between the tailgate and the top cover of the vehicle body, thereby improving the aesthetics of the vehicle.

[0024] Based on the hinge assembly of the embodiment of the present application, when the tailgate is connected to the vehicle body via the hinge assembly, there will be a gap between the tailgate and the vehicle body when the tailgate is in a closed state, and the shape of the hinge assembly will continuously change during the process of the tailgate being opened or closed relative to the vehicle body via the hinge assembly, and the hinge assembly with the changed shape drives the shielding member to move along the length direction of the vehicle body relative to the guide member; the specific process is: when the tailgate is in a closed state, the shielding member is in a first position, and the shielding member partially overlaps with the gap between the tailgate and the top cover of the vehicle body to cover the gap between the tailgate and the top cover of the vehicle body, and during the process of opening the tailgate, the shape of the hinge assembly changes, and drives the shielding member to move from the first position to the second position, so that the overlapping area between the shielding member and the gap between the tailgate and the top cover of the vehicle body gradually decreases, and the overlapping area between the shielding member and the guide member gradually increases to avoid the shape change of the hinge assembly.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] In the related art, the tailgate is usually connected to the top cover of the vehicle body through a single-axis hinge, so that the tailgate can rotate relative to the vehicle body. In some vehicles, the tailgate is connected to the vehicle body by other structures other than the single-axis hinge, such as a multi-link structure. When the multi-link structure is used, due to the large size of the multi-link structure in the length direction of the vehicle, there may be a significant gap between the tailgate and the top cover of the vehicle body when the tailgate is closed, thereby affecting the aesthetics of the vehicle.

[0033] To solve the above technical problems, please refer to Figure 1 to Figure 2 As shown, a first aspect of the present application proposes a hinge assembly, which can cover the gap between the top cover of the vehicle body and the tailgate when the tailgate is in a closed state.

[0034] Please refer to Figure 1 to Figure 2 As shown, the hinge assembly is used to connect the vehicle body and the back door. When the back door is in the closed state, there is a gap between the vehicle body and the back door. The hinge assembly includes a guide 10, a shield 20 and a hinge assembly 30. The guide 10 is fixed to the top cover of the vehicle body; the shield 20 is slidably connected to the guide 10, and the shield 20 has a first position and a second position; the hinge assembly 30 is used to connect the back door and the vehicle body, the shield 20 is rotatably connected to the hinge assembly 30, and the hinge assembly 30 can drive the back door to move between the maximum open position and the closed position. The hinge assembly 30 can also drive the shield 20 to move between the first position and the second position along the length direction of the vehicle body. Among them, when the back door is in the closed state, the shield 20 is in the first position and covers the gap between the back door and the top cover of the vehicle body; when the back door is in the open state, the shield 20 is in the second position.

[0035] It can be understood that as long as the tailgate and the top cover of the vehicle body are connected by a hinge assembly, the technical solution of the embodiment of the present application can be adopted to block the gap between the top cover of the vehicle body and the tailgate. The tailgate in the embodiment of the present application can be a hatchback tailgate or an upper and lower opening tailgate. The upper tailgate in the upper and lower opening tailgate can be rotatably connected to the top cover of the vehicle body by a hinge assembly.

[0036] The guide member 10 is used to guide the movement direction of the shielding member 20. In some embodiments of the present application, the guide member 10 has a guide groove 11 arranged along the length direction of the vehicle body; the shielding member 20 is at least partially located in the guide groove 11 and is slidably connected to the groove wall of the guide groove 11. The guide groove 11 arranged along the length direction of the vehicle body on the guide member 10 enables the shielding member 20 to move along the length direction of the vehicle body, thereby achieving guidance of the movement direction of the shielding member 20 by the guide member 10.

[0037] Based on the hinge assembly 30 of the embodiment of the present application, when the back door is connected to the vehicle body via the hinge assembly 30, there will be a gap between the back door and the vehicle body when the back door is in a closed state, and the shape of the hinge assembly 30 will continuously change when the back door is opened or closed relative to the vehicle body via the hinge assembly 30, and the hinge assembly 30 with a changed shape drives the shielding member 20 to move relative to the guide member 10 along the length direction of the vehicle body; the specific process is: when the back door is in a closed state, the shielding member 20 is in the first position, and the shielding member 20 is partially between the back door and the top cover of the vehicle body. The gap between the shielding member 20 and the top cover of the vehicle body overlaps to cover the gap between the back door and the top cover of the vehicle body, and the overlapping area with the guide member 10 is minimized. During the opening process of the back door, the shape of the hinge assembly 30 changes, and drives the shielding member 20 to move from the first position to the second position, so that the overlapping area between the shielding member 20 and the gap between the back door and the top cover of the vehicle body gradually decreases, and the overlapping area between the shielding member 20 and the guide member 10 gradually increases to avoid the shape change of the hinge assembly 30. When the back door is in the maximum open position, the overlapping area between the shielding member 20 and the guide member 10 is the largest.

[0038] Please refer to Figures 1 to 3 As shown, in some embodiments of the present application, the guide groove 11 includes a receiving groove 111 and a limiting groove 112 connected to the receiving groove 111; the shielding member 20 includes a main body 21 and a limiting portion 22, and the main body 21 is at least partially located in the receiving groove 111; the limiting portion 22 is fixedly connected to the main body 21, and the limiting portion 22 is located in the limiting groove 112 and is slidably connected to the groove wall of the limiting groove 112. The limiting portion 22 is located in the limiting groove 112, which can not only realize the sliding connection between the shielding member 20 and the guide member 10, but also the cooperation between the limiting portion 22 and the limiting groove 112 can prevent the shielding member 20 and the guide member 10 from being separated from each other.

[0039] Please refer to Figure 1 to Figure 2As shown, in some embodiments of the present application, the number of the limiting grooves 112 is two, and the two groove walls of the accommodating groove 111 parallel to the length direction of the vehicle body are partially recessed to form two limiting grooves 112, and the number of the corresponding limiting parts 22 is two, and the two limiting parts 22 are respectively located in the two limiting grooves 112, and the two sliding sub-parts are located on two oppositely arranged side walls of the main body 21 parallel to the length direction of the vehicle body.

[0040] As for the structure of the main body 21, in some embodiments of the present application, the main body 21 includes a sliding sub-part and a main body sub-part, the sliding sub-part is in the receiving groove 111, and the two limiting parts 22 are fixed on two side walls of the sliding sub-part that are parallel to the length direction of the vehicle body and are arranged opposite to each other. In other embodiments of the present application, the main body 21 is entirely in the receiving groove 111, and the two sliding sub-parts are on two side walls of the main body 21 that are parallel to the length direction of the vehicle body and are arranged opposite to each other.

[0041] In some embodiments of the present application, when the shielding member 20 is in the second position, the shielding member 20 and the guide member 10 completely overlap in the height direction of the vehicle body. When the shielding member 20 is in the second position, the tailgate is in the maximum opening position. At this time, the length of the guide member 10 can be reduced to make the vehicle body structure simple and reasonable.

[0043] The tailgate is connected to the vehicle body via a connecting rod structure 32. The shape of the connecting rod structure 32 changes continuously when the tailgate rotates relative to the vehicle body. The connecting rod structure 32 with continuously changing shape drives the first transmission member 31 to move at least in the length direction of the vehicle body, and then drives the shielding member 20 to move along the length direction of the vehicle body through the first transmission member 31.

[0044] The avoidance gap 23 is used to accommodate one end of the first transmission member 31. When the first transmission member 31 rotates relative to the shielding member 20, the avoidance gap 23 can prevent interference between the first transmission member 31 and the shielding member 20. It can be understood that the avoidance gap 23 passes through the main body 21 or the main body sub-part and the sliding sub-part in sequence along the height direction of the vehicle body.

[0045] Please refer to Figure 1 to Figure 2As shown, in some embodiments of the present application, the connecting rod structure 32 includes a mounting seat 321, a first connecting member 322, a second connecting member 323 and a third connecting member 324, the mounting seat 321 is fixedly connected to the top cover of the vehicle body, the first connecting member 322 and the mounting seat 321 are rotatably connected at a first hinge point, the second connecting member 323 and the first connecting member 322 are connected at a second hinge point, the second connecting member 323 is fixedly connected to the back door, the third connecting member 324 and the second connecting member 323 are connected at a third hinge point, and the third connecting member 324 and the mounting seat 321 are connected at a fourth hinge point.
