Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a door assembly and a vehicle. Background Art

[0002] Based on current technological developments and user aesthetic needs, taillights have become a vehicle highlight and are becoming increasingly common. Since taillights are typically mounted on the tailgate sheet metal, changes to the tailgate design affect their installation and coordination.

[0003] Existing taillights, similar to conventional tailgate light installation methods, utilize heat-inserted bolts or sheet metal nuts attached to the lamp. For example, some vehicles utilize this method, with the lamp mounted on the tailgate outer panel. However, this arrangement requires clearance within the tailgate inner panel to ensure proper assembly gun access. When the tailgate glass is sliding, it must maintain a minimum clearance of 10mm from surrounding components. Conventional installation methods require heat-inserted bolts or sheet metal nuts on the taillight housing. Furthermore, to ensure access, a hole must be drilled in the tailgate inner panel. This hole is located precisely at the rounded corner of the tailgate inner panel, making it difficult to drill. Furthermore, the large gap between the taillight and the inner panel makes the nuts or bolts required for installation easily fall off, complicating alignment. Finally, the nuts or bolts required for installation inevitably protrude from the tailgate outer panel, resulting in a clearance of less than 10mm from the tailgate glass. Therefore, a new installation form of running through taillight is needed badly. Summary of the Invention

[0023] 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.

[0024] 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.

[0025] like Figure 1 As shown, according to an embodiment of the present invention, the door body assembly includes a lamp 1, an exterior panel 2, a windshield 3, a first sheet metal door body 4 and a second sheet metal door body 5. The windshield 3 is slidably arranged between the first sheet metal door body 4 and the second sheet metal door body 5. The exterior panel 2 is located on the side of the first sheet metal door body 4 away from the windshield 3. The lamp 1 is provided with a first limiting portion 121 and a first clamping portion 122 spaced apart. The first sheet metal door body 4 is provided with a second limiting portion and a second clamping portion 41 spaced apart. The second limiting portion and the first limiting portion 121 are rotatably matched to limit the lamp 1 at least in the Z-axis direction. The second clamping portion 41 is clamped with the first clamping portion 122. In the Z-axis direction, the height of the upper edge of the exterior panel 2 is higher than the height of the second clamping portion 41, and the height of the upper edge of the exterior panel 2 is lower than the height of the second limiting portion.

[0026] To elaborate, the assembly of the first limiting portion 121 and the second limiting portion is hidden by the lamp 1 from the outside and will not be exposed to the outside. The assembly between the first clamping portion 122 and the second clamping portion 41 is lower than the height of the upper edge of the exterior panel 2 and can be hidden by the exterior panel 2 and will not be exposed to the outside. In this way, during assembly, the first clamping portion 122 is first extended between the exterior panel 2 and the first sheet metal door body 4, and then the first limiting portion 121 and the second limiting portion are matched, with the first limiting portion 121 and the second limiting portion matched as the fulcrum, as shown in FIG. Figure 1As shown, the lamp 1 is rotated in a direction parallel to the paper surface, thereby realizing the engagement of the first clamping portion 122 and the second clamping portion 41, and completing the assembly between the lamp 1 and the first sheet metal door body 4. In this way, the lamp 1 is first limited in the Z-axis direction by the cooperation between the first limiting portion 121 and the second limiting portion. The first limiting portion 121 and the second limiting portion do not limit the lamp 1 in the X-axis direction and the Y-axis direction. In this way, after the lamp 1 cannot move in the Z-axis direction, the first clamping portion 122 and the second clamping portion 41 are aligned, which can reduce the difficulty of accurate alignment. Figure 1 As shown, the lamp 1 rotates with point e as the fulcrum, and fg is the moving track of the upper edge of the first clamping portion 122 .

[0027] Among them, the first sheet metal door body 4 and the second sheet metal door body 5 jointly define a connected installation groove, and the windshield 3 can be slidably arranged in the installation groove. The installation groove includes a connected first sub-groove and a second sub-groove. The first sub-groove is located above the second sub-groove, and the width of the first sub-groove is smaller than the width of the second sub-groove. The second sub-groove is also provided with a driving component for driving the windshield 3 to slide.

[0028] It should be noted that after the first clamping portion 122 and the second clamping portion 41 are clamped together, they can limit the position of the lamp 1 in the X-axis, Y-axis, and Z-axis directions, or they can limit the position of the lamp 1 in the X-axis and Y-axis directions. Alternatively, the lamp 1 can be limited in the X-axis or Y-axis direction, and the exterior panel 2 and the first sheet metal door body 4 can be used to limit the position of the lamp 1 in the Y-axis or X-axis direction. Specifically, after the first clamping portion 122 and the second clamping portion 41 are clamped together, the lamp 1 is not limited in the Z-axis direction. This can correspondingly reduce the molding and positioning accuracy of the first limiting portion 121, the second limiting portion, the first clamping portion 122, and the second clamping portion 41, allowing for a certain degree of error during the manufacturing process and reducing manufacturing costs.

[0029] In the above description, the door body assembly is used as a tailgate, the X-axis direction refers to the front and rear direction of the vehicle when the door body assembly is applied to the vehicle; the Y-axis direction refers to the left and right direction of the vehicle when the door body assembly is applied to the vehicle; and the Z-axis direction refers to the up and down direction of the vehicle when the door body assembly is applied to the vehicle.

[0030] It is understandable that the door body assembly can be used as a back door, a front side door, or a rear side door.

[0031] In addition, one of the first limiting portion 121 and the second limiting portion can be configured as a groove or a hole, and the other can be configured as a column or a stick, wherein the cross section of the stick can be square, rectangular, elliptical, triangular or other shapes.

[0032] In addition, the lamp 1 includes but is not limited to a through taillight and an ordinary taillight, and is particularly suitable for a through taillight.

[0033] like Figure 1 As shown, according to the door body assembly of an embodiment of the present invention, the lamp 1 can be fixed on the first sheet metal door body 4 through the cooperation of the first limiting portion 121 and the second limiting portion, and the cooperation of the first clamping portion 122 and the second clamping portion 41, thereby simplifying the difficulty of installing and fixing the lamp 1.

[0034] According to the door body assembly of an embodiment of the present invention, the first limiting portion 121 is configured as a first limiting pin, the second limiting portion is configured as a first limiting groove, the first limiting pin is passed through the first limiting groove, and the first limiting pin is set away from the horizontal plane in a direction close to the first sheet metal door body 4.

[0035] Among them, the first limit groove can not only limit the first limit pin shaft, but also facilitate the insertion of the first limit pin shaft due to the top opening. The first limit pin shaft is set away from the horizontal plane in the direction close to the first sheet metal door body 4, so that the force applied by the lamp 1 to the first sheet metal door body 4 through the first limit pin shaft can be decomposed into a component with a vertical direction, so that the first limit pin shaft and the first limit groove are more stable after assembly and are not easy to shake out.

[0036] It can be understood that the description of the relative position relationship between the first limiting pin and the horizontal plane is based on the position of the door body assembly when assembled in the vehicle.

[0037] According to the door assembly of an embodiment of the present invention, the angle ɑ between the first limit pin and the horizontal plane satisfies: 10°≤ɑ≤80°. If ɑ is too large, the first limit pin will not be easily inserted into the first limit groove. If ɑ is too small, the first limit pin will easily fall out of the first limit groove. Therefore, it is necessary to set a suitable size of ɑ. Among them, ɑ can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° and 80°, etc.

[0038] According to the door assembly of the embodiment of the present invention, there are multiple first limiting portions 121 and multiple second limiting portions, and the multiple first limiting portions 121 correspond to the multiple second limiting portions in a one-to-one manner.

[0039] like Figure 2 As shown, in some embodiments, the second clamping portion 41 is clamped with the first clamping portion 122 to limit the lamp 1 in the Y-axis direction. The lamp 1 includes a lamp housing 12 and a light distribution lens 11 fixed on the lamp housing 12. The lamp housing 12 is also provided with a first limiting hole. The first sheet metal door body 4 is provided with a second limiting hole 42. The first limiting hole and the second limiting hole 42 are aligned and connected to jointly sleeve the fastener 13. The fastener 13 is used to limit the lamp 1 in the X-axis direction. The exterior panel 2 is detachably provided on the first sheet metal door body 4.

[0040] Specifically, the first clamping portion 122 and the second clamping portion 41 are clamped to limit the lamp 1 in the Y-axis direction, which can reduce the difficulty of clamping the first clamping portion 122 and the second clamping portion 41, reduce the molding and positioning accuracy of the first clamping portion 122 and the second clamping portion 41, allow a certain error in the production process, and reduce manufacturing costs.

[0041] When installing, after the first clamping portion 122 and the second clamping portion 41 are clamped, the position of the lamp 1 and the first sheet metal door body 4 is adjusted so that the first limiting hole and the second limiting hole 42 are aligned, and the fastener 13 is clamped into the first limiting hole and the second limiting hole 42, thereby limiting the lamp 1 in the X-axis direction. In this way, while limiting the X-axis direction, Y-axis direction and Z-axis direction of the lamp 1 respectively, the difficulty of assembling the lamp 1 and the first sheet metal door body 4 is further reduced. Among them, the exterior panel 2 is detachably provided on the first sheet metal door body 4, which is convenient for assembling the lamp 1 on the first sheet metal door body 4 first, and then installing the exterior panel 2 on the first sheet metal door body 4 to make space for the installation of the fastener 13. At the same time, since the exterior panel 2 and the lamp 1 are both installed on the first sheet metal door body 4, the clearance and surface difference between the lamp 1 and the first sheet metal door body 4 can be effectively guaranteed.

[0042] In some embodiments, the second clamping portion 41 is configured as a waist-shaped hole extending along the Z-axis, and the first clamping portion 122 is configured as a second limiting pin, with the waist-shaped hole sleeved outside the second limiting pin. In this way, the first clamping portion 122 can be limited in the Y-axis direction while reducing the difficulty of assembling the first clamping portion 122 and the second clamping portion 41, reducing the molding and positioning accuracy of the first clamping portion 122 and the second clamping portion 41, allowing for a certain degree of error in the manufacturing process, and reducing manufacturing costs.

[0043] like Figure 2 As shown, in some embodiments, the fastener 13 includes a fastener body and a plurality of limiting portions provided on the surface of the fastener body. A limiting head is further provided at one end of the fastener body close to the lamp 1. The diameter of the limiting head is larger than the diameter of the fastener body. The limiting portion is deformable or movable. A first wall thickness region and a second wall thickness region 123 are provided on the lamp housing 12. The thickness of the first wall thickness region is smaller than the thickness of the second wall thickness region 123. The first clamping portion 122 is provided in the first wall thickness region. Figure 1 The first wall thickness area is shown, and the second wall thickness area 123 is provided with a first limiting hole, and at least one limiting portion is clamped on the surface of the side of the first sheet metal door body 4 facing away from the lamp 1.

[0044] To elaborate, since the first clamping portion 122 and the second clamping portion 41 only limit the position of the lamp 1 in the Y-axis direction or limit the position of the Y-axis direction and the Z-axis direction, a smaller thickness can meet the structural strength requirement. Therefore, the first clamping portion 122 can be set in the first wall thickness area, and the first limiting hole and the second limiting hole 42 cooperate with the fastener 13 to limit the lamp 1 in the X-axis direction, so that the lamp 1 needs to withstand the force in the X-axis direction in the second wall thickness area 123. Therefore, a larger thickness is required to meet the structural strength requirement. Therefore, the first limiting hole is set in the second wall thickness area 123. Secondly, at least one limiting portion is clamped on the side surface of the first sheet metal door body 4 facing away from the lamp 1, and the limiting head is against the side of the lamp 1 facing away from the first sheet metal door body 4, which can prevent the fastener 13 from escaping from the first limiting hole and the second limiting hole 42. The limiting part is deformable or movable, so that when the fastener body is inserted into the first limiting hole and the second limiting hole 42 in sequence from the side of the lamp 1 away from the first sheet metal door body 4, after the limiting part passes through the side of the first sheet metal door body 4 away from the lamp 1, the limiting part rests on the first sheet metal door body 4 by restoring its position or shape.

[0045] The fastener 13 may be an open-end rivet or a plastic rivet with barbs.

[0046] like Figure 1 As shown, in some embodiments, the lamp 1 includes a lamp housing 12 and a photometric lens 11 fixed to the lamp housing 12. The lamp housing 12 includes a first bent wall portion that is face-to-face matched with the first sheet metal door body 4. The first bent wall portion is Z-shaped and includes a first sub-wall portion, a second sub-wall portion, and a third sub-wall portion ab. The first sub-wall portion and the third sub-wall portion ab are respectively connected to two ends of the second sub-wall portion. The first sub-wall portion is located below the third sub-wall portion. The third sub-wall portion ab is connected to a fourth sub-wall portion. The angle between the fourth sub-wall portion and the third sub-wall portion ab is obtuse. The fourth sub-wall portion is provided with a first limiting pin. The obtuse angle between the fourth sub-wall portion and the third sub-wall portion ab ensures that the first limiting pin is deviated from the horizontal plane and disposed in a direction close to the first sheet metal door body 4, while increasing the angle between the fourth sub-wall portion and the first limiting pin, thereby reducing molding difficulty and improving the yield rate.

[0047] like Figure 2 As shown, in some embodiments, the first sub-wall portion is provided with a first wall thickness region and a second wall thickness region 123, and the first wall thickness region 123 is arranged along the Y-axis. In this way, the first clamping portion 122 and the first limiting portion 121 are spaced apart without extending the length of the first sub-wall portion in the Z-axis direction, thereby appropriately reducing the size of the lamp 1 and saving raw materials and reducing costs.

[0048] like Figure 1As shown, in some embodiments, the lamp 1 is further provided with at least one support portion 124, which is disposed adjacent to the second clamping portion 41 and abuts against the first sheet metal door 4. This can increase the contact area between the lamp 1 and the first sheet metal door 4, thereby increasing the stability of the lamp 1 connected to the first sheet metal door 4 and preventing the lamp 1 from shaking when the vehicle is traveling in various extreme road conditions.

[0049] According to the door assembly of this embodiment of the present invention, the minimum distance D between the lamp 1 and the windshield 3 satisfies the following: 5mm ≤ D < 10mm. If D is too large, rain, dust, and the like can easily fall between the lamp 1 and the windshield 3. If D is too small, the lamp 1 may interfere with the windshield 3. Therefore, an appropriate value for D is required. Examples of D include 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm.

[0050] A vehicle according to an embodiment of the present invention includes the above-mentioned door assembly.

[0051] According to the vehicle of the embodiment of the present invention, the lamp 1 can be fixed to the first sheet metal door body 4 through the cooperation between the first limiting portion 121 and the second limiting portion, and the cooperation between the first clamping portion 122 and the second clamping portion 41, thereby simplifying the difficulty of installing and fixing the lamp 1.
