Technical Field

[0001] The present invention generally relates to the field of vehicle components. More specifically, the present invention relates to a door assembly and a vehicle including such a door assembly. Background Art

[0002] The door assembly includes an inner door panel and a trim panel mounted to the inner side of the inner door panel, and the two are usually connected by a snap device. More specifically, a plurality of protruding snap seats are usually integrally provided on the trim panel, and the trim panel is mounted to the inner door panel by a plurality of snaps that match these snap seats.

[0003] One side of a traditional snap seat has an opening for the snap to enter, so only the remaining several side walls interfere with the snap to limit the position of the snap. Such a structure may cause the snap to shift and loosen in the snap seat and has a risk of falling off, thus failing to ensure the accuracy and stability of the door assembly during the assembly process, increasing the assembly difficulty and reducing the assembly efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a door assembly that can avoid the falling off of the snap during the assembly process and keep the snap stably on the snap seat, thereby improving the assembly efficiency and safety performance of the door assembly.

[0005] To this end, a first aspect of the present invention provides a door assembly, including an inner door panel and a trim panel. Wherein, the trim panel is provided with snap seats and is mounted to the inner side of the inner door panel by snaps fixed to the snap seats. The snap seats include a top wall and side walls. Wherein, the top wall includes: an edge portion, the edge portion includes a first edge portion connected to the side walls and a second edge portion not connected to the side walls; and a plurality of elastic limiting members, each of the plurality of elastic limiting members extends from the edge portion towards the center of the top wall and overhangs the edge portion, and the plurality of elastic limiting members jointly define a limiting hole, and the limiting hole communicates with the second edge portion through an opening allowing the snap to enter the limiting hole; and, the snap includes a neck, and the neck passes through the limiting hole and abuts against each of the plurality of limiting members to keep the neck fixed in a plane perpendicular to the axis of the limiting hole.

[0006] According to an optional embodiment of the present invention, the plurality of elastic limiting members are circumferentially and uniformly distributed around the limiting hole, and each free end of the plurality of elastic limiting members has an abutting surface that abuts against the neck in a plane perpendicular to the axis of the limiting hole.

[0007] According to an alternative embodiment of the present invention, the distance between the abutting surface of one of the plurality of elastic limit members and the abutting surface of an adjacent elastic limit member among the plurality of elastic limit members is less than the diameter of the neck portion.

[0008] According to an alternative embodiment of the present invention, the top wall includes four elastic limit members that are circumferentially and uniformly distributed around the limit hole.

[0009] According to an alternative embodiment of the present invention, the buckle support further includes: a base plate that extends from the inner surface of the side wall; and at least one support rib that protrudes from the base plate toward the top wall and defines a card slot that matches the engaging portion of the buckle with the top wall.

[0010] According to an alternative embodiment of the present invention, the opening has a shape that tapers from the second edge portion toward the limit hole.

[0011] A second aspect of the present invention provides a vehicle, including a door assembly according to the first aspect of the present invention.

[0012] According to an alternative embodiment of the present invention, the door assembly is a tailgate assembly of the vehicle.

[0013] Compared with the prior art, the door assembly according to the present invention has multiple advantages, especially: the elastic limit members limit the buckle from multiple directions, so that the engaging portion of the buckle is stably held in the card slot of the buckle support. Therefore, the assembly process is more convenient and fast, and the assembly stability is improved, avoiding the risk of assembly looseness. The door assembly has a simple structure, is easy to install, has a low cost, and can be widely applied to various types of vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 5 It is a schematic diagram after cutting along Figure 3 the middle plane B-B. Specific Embodiments

[0020] The implementation and use of specific embodiments will be discussed in detail below. However, it should be understood that the specific embodiments discussed are only illustrative of specific ways of implementing and using the present invention, and do not limit the scope of the present invention.

[0021] In this specification, when describing the structural positions of various components, directional expressions such as "upper", "lower", "left", "right", etc. are not absolute but relative. When the components are arranged as shown in the figures, these directional expressions are appropriate, but when the positions of the components in the figures change, these directional expressions should also change accordingly.

[0022] In this specification and the accompanying drawings, the X1 direction represents the first diagonal direction of the snap support, the X2 direction represents the second diagonal direction of the snap support (i.e., the direction perpendicular to the X1 direction by 90 degrees), and the H direction represents the height direction of the snap support (i.e., the direction of the axis C of the limiting hole of the snap support, i.e., the up and down direction shown in the figure).

[0023] In this specification, unless otherwise clearly specified and limited, terms such as "fixed" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a direct connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those skilled in the art, the specific meanings of the above terms in this specification can be understood according to specific circumstances.

[0024] As Figure 1 and Figure 2 shown, the door assembly A of the present invention includes a door trim 400, a snap support 100, a snap 500, and a door inner panel 300. Among them, only partial assembly areas of the door trim 400 and the door inner panel 300 are schematically shown. More specifically, the door trim 400 is integrally formed with the snap support 100, and through holes matching the snaps 500 are provided on the door inner panel 300, so that the door trim 400 is installed on the inner side (the side facing the interior of the vehicle) of the door inner panel 300 by the snaps 500 fixed to the snap support 100 and passing through the through holes. Preferably, the door assembly A is the tailgate assembly of the vehicle V, that is, the door inner panel 300 is the tailgate inner panel, and the door trim 400 is the tailgate trim. The door assembly A can also be other door assemblies of the vehicle V, and the present invention does not limit this.

[0025] As Figures 3 to 5As shown, the snap support 100 includes a top wall 31, side walls 21, 22, 23, a base plate 34, and support ribs 35.

[0026] More specifically, the side walls 21, 22, 23 include a first side wall 21, a second side wall 22 opposite to the first side wall 21, and a third side wall 23 connecting the first side wall 21 and the second side wall 22. These three side walls 21, 22, 23 together form a substantially U-shaped configuration.

[0027] The top wall 31 includes an edge portion 32 and a plurality of elastic limiting members 33. Among them, the edge portion 32 includes a first edge portion 321 connected to the three side walls 21, 22, 23 and a second edge portion 322 not connected to the three side walls 21, 22, 23. Each of the plurality of elastic limiting members 33 extends from the edge portion 32 towards the center of the top wall 31 and overhangs the edge portion 32. This cantilever structure allows the elastic limiting members 33 to undergo a certain degree of elastic deformation.

[0028] Preferably, the top wall 31 includes a first elastic limiting member 33a, a second elastic limiting member 33b, a third elastic limiting member 33c, and a fourth elastic limiting member 33d that are circumferentially and uniformly distributed around the limiting hole 39. And each of the free ends of these four elastic limiting members 33a, 33b, 33c, 33d has a contact surface 337 that abuts against the neck 504 in a plane perpendicular to the axis C of the limiting hole 39. That is to say, the contact surfaces 337 of the free ends of these four elastic limiting members 33a, 33b, 33c, 33d jointly define the limiting hole 39, and the limiting hole 39 communicates with the second edge portion 322 through an opening 25 that allows the snap 500 to enter the limiting hole 39. In the illustrated embodiment, the opening 25 is defined by the opposite edges of two adjacent elastic limiting members (i.e., the illustrated first limiting member 33a and the second limiting member 33b), and has a shape that tapers from the second edge portion 322 towards the limiting hole 39. The flared tapered shape of the opening 25 is conducive to guiding the snap 500 into the opening 25.

[0029] The base plate 34 extends from the inner surfaces of the three side walls 21, 22, 23 in a manner opposite to the top wall 31, and at least one support rib 35 (such as two parallel support ribs 35 shown in the figure) protrudes from the upper surface of the base plate 34 towards the top wall 31. Thus, the top wall 31 and the support ribs 35 jointly define a card slot 30.

[0030] The buckle 500 includes a base portion 503 that abuts against the upper surface of the top wall 31, a tapered main body portion 501 that extends upward from the base portion 503 to be snap-fitted to the inner door panel 300, a neck portion 504 that extends downward from the base portion 503 to pass through the limiting hole 39 and abut against four elastic limiting members 33a, 33b, 33c, 33d, and a disc-shaped snap-fitting portion 502 that extends downward from the neck portion 504 to match the card slot 30.

[0031] More specifically, the distance L between the abutting surfaces 337 of one of the four elastic limiting members 33a, 33b, 33c, 33d and the abutting surfaces 337 of the adjacent elastic limiting members is less than the diameter D of the neck portion 504 of the buckle 500. Thus, the neck portion 504 of the buckle 500 can enter the limiting hole 39 through the opening 25 due to the elastic deformation of the elastic limiting members, and is held in the limiting hole 39 by the abutting surfaces 337 of the free ends of the elastic limiting members, and will not slip through the opening 25.

[0032] In fact, the structure of this buckle support 100 can keep the neck portion 504 of the buckle 500 fixed in a plane perpendicular to the axis C of the limiting hole 39. More specifically, the first elastic limiting member 33a and the fourth elastic limiting member 33d abut against the neck portion 504 opposite to each other to keep the neck portion 504 fixed in the X1 direction; the second elastic limiting member 33b and the third elastic limiting member 33c abut against the neck portion 504 opposite to each other to keep the neck portion 504 fixed in the X2 direction perpendicular to the X1 direction. In addition, the top wall 31 and the support rib 35 abut against the snap-fitting portion 502 opposite to each other to keep the snap-fitting portion 502 fixed in the H direction. It can be understood that "keep fixed" here does not mean absolute immobility, but also includes restoring to the initial fixed position through the four elastic limiting members 33a, 33b, 33c, 33d when the buckle 500 makes a slight movement.

[0033] As Figure 5As shown, when assembling the door assembly A, first, the buckle 500 is pushed into the buckle support 100 through the opening 25. Due to the elastic deformation of the first elastic limiting member 33a and the second elastic limiting member 33b, the neck 504 of the buckle 500 crosses the relative edges of the first elastic limiting member 33a and the second elastic limiting member 33b and enters the limiting hole 39, and the clamping portion 502 enters the card slot 30 bounded by the top wall 31 and the support rib 35. And through the elastic reset of the first elastic limiting member 33a and the second elastic limiting member 33b, the neck 504 stably abuts against the four elastic limiting members 33a, 33b, 33c, and 33d, so that the buckle 500 is stably fixed to the buckle support 100. Then, the buckle 500 is passed through the through hole of the inner door panel 300 to install the door trim 400 to the inner door panel 300, so as to obtain the entire assembled door assembly A. During the process of installing the door trim 400 to the inner door panel 300, the buckle 500 may be slightly offset due to external force. At this time, for the neck 504 of the buckle 500, the first elastic limiting member 33a and the fourth elastic limiting member 33d can apply a force in the X1 direction to it, and the second elastic limiting member 33b and the third elastic limiting member 33c can apply a force in the X2 direction to it, so that the buckle 500 can move back to the initial fixed position again, preventing the buckle 500 from falling off the card slot 30.

[0034] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative concept of the present invention, those skilled in the art can make various changes and improvements to the above-disclosed concept, but all belong to the protection scope of the present invention.

[0035] The description of the above embodiments is exemplary rather than restrictive, and the protection scope of the present invention is determined by the claims.
