Description

Technical Field

[0001] The invention relates to a vehicle, and in particular provides a guide rail end cover for a door assembly, a door assembly and a vehicle. Background Art

[0002] The front door of an existing vehicle usually includes a door frame, fixed glass, sliding glass, guide rails and guide rail end covers. The guide rails are arranged between the fixed glass and the sliding glass, and are used to support the slide grooves of the fixed triangular window glass and the sliding glass. The guide rails are usually sheet metal structures, providing the necessary strength and rigidity. The guide rail end covers are usually made of rubber or similar soft materials, and are used to close the upper ports of the guide rails and connect to the door frame. This structure has the following technical problems in practical applications:

[0003] First, since the guide rail end cap is usually made of rubber material, while the guide rail is usually made of metal sheet material, the appearance of the two is quite different, which affects the appearance of the door assembly. Although the use of hard materials similar to the appearance of the guide rail to make the guide rail end cap can solve the above problem, the surface of the door frame is usually provided with a film. When the hard material abuts against the door frame, it is easy to squeeze the film, causing the film to wrinkle or be damaged.

[0004] Secondly, the guide rail end cap is usually connected to the guide rail by partially inserting the guide rail end cap into the guide rail port. However, since the guide rail end cap is made of soft material, its rigidity is poor and it is easy to deform during the plug-in and assembly process. This will increase the difficulty of assembling the door assembly and may also cause the guide rail end cap to be assembled in a deformed state, affecting the appearance of the door assembly.

[0005] Therefore, there is an urgent need in the art for a guide rail end cover for a door assembly, a door assembly and a vehicle to solve the above problems. Summary of the invention

[0006] The present invention aims to solve the above technical problems, that is, to solve the problems of appearance effect and easy deformation of existing guide rail end covers made of soft materials.

[0007] In a first aspect, the present invention provides a guide rail end cover for a vehicle door assembly, wherein the vehicle door assembly includes a guide rail and a door frame, and the guide rail end cover includes a hard part and a soft part connected to the hard part, wherein the hard part is used to connect the guide rail, and the soft part is used to connect the door frame.

[0008] In a specific embodiment of the guide rail end cover, the hard portion is provided with a connecting portion, the connecting portion includes at least one of a stepped surface, a wavy surface, and a serrated surface, and the soft portion is bonded to the connecting portion.

[0009] In a specific implementation of the above-mentioned guide rail end cover, a connecting hole is provided on the hard portion, and the soft portion partially extends into the connecting hole and is bonded to the inner wall of the connecting hole.

[0010] In a specific embodiment of the guide rail end cover, the soft portion extends from the opening of the connecting hole into the connecting hole, and a cross-sectional area of ​​the soft portion partially located in the connecting hole is larger than an area of ​​the opening.

[0011] In a second aspect, the present invention provides a vehicle door assembly, which includes a guide rail, a door frame and the above-mentioned guide rail end cover, wherein the hard part is spaced apart from the door frame, and the soft part abuts against the door frame so that the soft part closes the gap between the hard part and the door frame.

[0012] In the door assembly of the guide rail end cover, one of the hard portion and the guide rail includes a first connecting portion, and the other includes a second connecting portion, the first connecting portion is connected to the second connecting portion, so that the guide rail end cover is connected to the guide rail; and / or

[0013] The hard part and the guide rail are bonded and connected.

[0014] In the door assembly of the guide rail end cover, the first connection portion includes a protrusion, and the second connection portion includes a socket, and the protrusion can extend into the socket to connect the guide rail end cover to the guide rail; and / or

[0015] The first connecting portion includes a protrusion, the second connecting portion includes a plate, the protrusion abuts against the plate to limit the relative position of the hard portion and the guide rail; and / or

[0016] The first connection portion includes a plurality of protrusions, and the second connection portion includes a plate, and the plurality of protrusions clamp the plate.

[0017] In the above-mentioned door assembly of the guide rail end cover, the hard portion includes a first outer wall, and the first outer wall is provided as a part of the outer wall of the door assembly; and / or

[0018] The soft portion is arranged inside the vehicle door assembly.

[0019] In the above-mentioned door assembly with a guide rail end cover, the first outer wall and a part of the outer wall of the guide rail are located on the same plane; and / or

[0020] The outer wall of the guide rail is provided with a coating, and the first outer wall and the coating are located on the same plane.

[0021] In a third aspect, the present invention provides a vehicle comprising the above-mentioned door assembly.

[0022] In the case of adopting the above technical solution, the guide rail end cover of the present invention includes a hard part and a soft part connected to the hard part. Compared with the guide rail end cover made entirely of soft materials in the prior art, the hard part has higher rigidity, is less likely to deform, and is easier to connect to the guide rail. The soft part is used to connect to the door frame, which can prevent the hard part from squeezing the film on the surface of the door frame when it abuts against the door frame, so that the appearance of the door assembly is better.

[0023] Furthermore, a connecting portion is provided on the hard portion, and the soft portion is bonded to the connecting portion. The connecting portion includes at least one of a stepped surface, a wavy surface, and a serrated surface. This arrangement can increase the bonding area between the hard portion and the soft portion, so that the soft portion is bonded more firmly.

[0024] Furthermore, a connection hole is provided on the hard part, the soft part can extend into the connection hole, and the soft part is bonded to the inner wall of the connection hole. This arrangement further increases the bonding area of ​​the soft part to improve the connection stability. Furthermore, the cross-sectional area of ​​the soft part located in the connection hole is larger than the opening area of ​​the connection hole. This arrangement can effectively prevent the soft part from escaping from the connection hole, thereby improving the connection strength between the soft part and the hard part.

[0025] Furthermore, the hard part is spaced apart from the door frame to avoid squeezing the film on the surface of the door frame when the hard part abuts against the door frame. This design can effectively prevent the hard part from directly contacting the door frame, thereby avoiding deformation or wrinkling of the film on the surface of the door frame caused by pressure. This structural setting not only greatly improves the appearance flatness and aesthetics of the door assembly, but also reduces the technical difficulty and complexity of door assembly, making the production and assembly process smoother, saving production costs and improving efficiency. The soft part abuts against the door frame, which can close the gap between the hard part and the door frame to prevent air and water leakage.

[0026] Furthermore, the hard part and the guide rail are mechanically connected to the second connecting part through the first connecting part. The hard part and the guide rail can also be connected by bonding. Furthermore, the hard part and the guide rail can also be connected by mechanical connection and bonding at the same time. This setting method can improve the connection strength between the two. This dual connection method can effectively resist potential loosening problems caused by environmental stress, temperature changes and long-term use, extend the service life of the components, simplify the production and assembly process, reduce dependence on precision machining tolerances, and improve production efficiency and consistency. The combination of multiple connection methods not only provides the necessary guarantee for high-intensity application scenarios, but also increases the durability and reliability of the structure, thereby improving the durability and user experience of the entire system. This improvement meets the needs of high-performance and high-reliability connections in practical applications.

[0027] Furthermore, the first connecting part and the second connecting part include multiple connection methods: through the interlocking structure of the socket and the protrusion, a reliable connection between the guide rail end cover and the guide rail is achieved, simplifying the installation process; the abutment between the protrusion and the plate limits the relative position of the hard part and the guide rail, ensuring the stability of the connection; the structure of multiple protrusions clamping the plate provides multi-point support and mechanical clamping effects, enhancing the connection strength, anti-slip ability and adaptability.

[0028] Furthermore, the first outer wall of the hard part is set as a part of the outer wall of the door assembly. Compared with the guide rail end cover made of soft material in the prior art, the appearance of the hard part is similar to that of the guide rail. Therefore, this arrangement can improve the appearance of the door assembly. The soft part is set inside the door assembly and will not affect the appearance of the door assembly, thereby improving the appearance.

[0029] Furthermore, the first outer wall and a part of the outer wall of the guide rail are located on the same plane, or the coating of the first outer wall and the outer wall of the guide rail are located on the same plane. This arrangement can visually achieve an overall integrated appearance of the door assembly, avoid abruptness or incoordination in appearance, and improve the aesthetics and refinement of the door system.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In order to solve the problems of appearance and easy deformation of the existing guide rail end caps made of soft materials, this embodiment discloses a vehicle, which includes a door assembly. Figure 1 and Figure 2 The vehicle door assembly includes a guide rail end cover 1, a guide rail 2, and a door frame 3.

[0051] Reference Figure 3 The guide rail end cover 1 includes a hard part 11 and a soft part 12. The hard part 11 is made of a hard material. In the present embodiment, the hard part 11 is made of a PMMA / ASA composite material (PMMA is polymethyl methacrylate, commonly known as plexiglass or acrylic; ASA is acrylonitrile-styrene-acrylate copolymer). The soft part 12 is made of a soft material. The soft part 12 has a certain elasticity or flexibility relative to the hard part 11, and can be deformed when the soft part 12 abuts against other structures. In the present embodiment, the soft part 12 is made of TPE (thermoplastic elastomer).

[0052] Regarding the material of the hard part 11, it should be noted that although the material of the hard part 11 in this embodiment is a PMMA / ASA composite material, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, such as other plastic hard materials. As long as the hard part 11 has sufficient rigidity and does not deform when connected to the guide rail 2, it does not deviate from the basic principle of the present invention and therefore falls within the scope of protection of the present invention.

[0053] Regarding the material of the soft part 12, it should be noted that although the material of the soft part 12 in this embodiment is TPE, this setting method is not a limitation of the present invention. Without departing from the principles of the present invention, technical personnel in this field may also adopt other settings in other embodiments, such as other rubber soft materials, which do not deviate from the basic principles of the present invention and therefore fall within the scope of protection of the present invention.

[0054] The soft part 12 is connected to the hard part 11. In this embodiment, the soft part 12 is formed on the hard part 11 by injection molding, so that the soft part 12 and the hard part 11 are bonded.

[0055] Furthermore, a connecting portion 111 is provided on the hard portion 11, and the soft portion 12 is bonded to the connecting portion 111. Figure 4 and Figure 5 In this embodiment, the connection portion 111 is in the shape of a stepped surface. This arrangement can increase the connection area between the soft portion 12 and the hard portion 11, so that the two are more firmly bonded.

[0056] Regarding the shape of the connecting portion 111, it should be noted that although the shape of the connecting portion 111 in the present embodiment is a stepped surface, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may also adopt other arrangements in other embodiments. For example, the shape of the connecting portion 111 may be a combination of one or more stepped surfaces, wavy surfaces, and serrated surfaces. As long as the connecting portion 111 can increase the contact area between the hard portion 11 and the soft portion 12, this does not deviate from the basic principles of the present invention and therefore falls within the scope of protection of the present invention.

[0057] Further, refer to Figure 6 The hard part 11 is provided with a connection hole 112, and the soft part 12 partially extends into the connection hole 112 and is bonded to the inner wall of the connection hole 112. The connection hole 112 can increase the connection area between the soft part 12 and the hard part 11, and can also make the connection between the two more firmly. Figure 7 and Figure 8 The shape of the connection hole 112 is a conical connection hole 112 or a stepped connection hole 112, and the soft part 12 extends from the small end of the connection hole 112 and fills the space inside the connection hole 112. The cross-sectional area of ​​the part of the soft part 12 inside the connection hole 112 is larger than the small end area of ​​the connection hole 112, so that the soft part 12 cannot be separated from the connection hole 112, so as to improve the connection stability between the soft part 12 and the hard part 11. Furthermore, the connection hole 112 can be a through hole, and the soft part 12 is penetrated in the through hole, and both ends of the soft part 12 penetrated in the through hole are connected to the main body of the soft part 12, such as Fig. 9 This arrangement can also enhance the connection stability between the soft part 12 and the hard part 11 .

[0058] Regarding the shape of the connection hole 112, it should be noted that although the shape of the connection hole 112 in the present embodiment is a tapered connection hole 112 or a stepped connection hole 112, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, as long as the opening area of ​​the connection hole 112 is smaller than the internal cross-sectional area of ​​the connection hole 112, the soft part 12 will be formed into a soft part 12 structure with a cross-sectional area larger than the opening of the connection hole 112 after foaming and molding in the connection hole 112, so as to limit the soft part 12 from being separated from the connection hole 112. This does not deviate from the basic principle of the present invention, and therefore falls within the protection scope of the present invention.

[0059] Regarding the shape of the inner wall of the connection hole 112, it should be noted that although the shape of the inner wall of the connection hole 112 in the present embodiment is a cylindrical surface, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, such as a prismatic surface, or an irregular curved surface, or a shape in which multiple planes and multiple curved surfaces are combined, as long as the contact area between the hard portion 11 and the soft portion 12 can be increased. This does not deviate from the basic principle of the present invention and therefore falls within the scope of protection of the present invention.

[0060] The hard part 11 is provided with a first connection part, and the guide rail 2 is provided with a second connection part, and the first connection part is connected with the second connection part, so that the guide rail end cover 1 is connected with the guide rail 2. Figure 3 The first connection portion includes a first bump 113, a second bump 114, a third bump 115, a fourth bump 116, a fifth bump 117 and a sixth bump 118. Fig.10 , the second connection part is a sheet metal structure at the upper end of the guide rail 2. The sheet metal structure is formed by bending and folding a metal plate, a part of which forms a C-shaped structure, and the C-shaped structure includes a first plate 121, a second plate 122, and a third plate 123 connected in sequence. The metal plate is bent at one end of the first plate 121 to form a first plug hole 124. The metal plate is bent at the left and right ends of the third plate 123 to form a second plug hole 125 and a third plug hole 126.

[0061] Reference Fig.11 The shape of the first protrusion 113 matches the shape of the first insertion hole 124, and the first protrusion 113 can be inserted into the first insertion hole 124. The shape of the second protrusion 114 matches the shape of the second insertion hole 125, and the second protrusion 114 can be inserted into the second insertion hole 125. The shape of the third protrusion 115 matches the shape of the third insertion hole 126, and the third protrusion 115 can be inserted into the third insertion hole 126.

[0062] The fourth protrusion 116 and the fifth protrusion 117 are both plate-shaped structures, the fourth protrusion 116 is fitted and abutted against the first plate 121, and the fifth protrusion 117 is fitted and abutted against the third plate 123. This connection structure can limit the position of the guide rail end cover 1 in the Y direction shown in the figure.

[0063] The first protrusion 113 and the fourth protrusion 116 are clamped on the upper and lower sides of the first plate 121, which can further limit the position of the guide rail end cover 1 in the Y direction shown in the figure. The sixth protrusion 118 abuts against the left side wall of the second plate 122, and the sixth protrusion 118 and the first protrusion 113 are clamped on the left and right ends of the first plate 121. This arrangement can limit the position of the guide rail end cover 1 in the X direction shown in the figure. Furthermore, the size of the first protrusion 113 is slightly smaller than the size of the first jack 124. This arrangement can compensate for the deviation between the guide rail end cover 1 and the guide rail 2, so that the first connecting portion and the second connecting portion are easier to connect.

[0064] The second protrusion 114 and the fifth protrusion 117 are clamped on the upper and lower sides of the third plate 123, which can further limit the position of the guide rail end cover 1 in the Y direction shown in the figure. The third protrusion 115 abuts against the left side wall of the second plate 122, and the third protrusion 115 and the second protrusion 114 are clamped on the left and right ends of the third plate 123. This arrangement can limit the position of the guide rail end cover 1 in the X direction shown in the figure. Furthermore, the size of the second protrusion 114 is slightly smaller than the size of the second jack 125. This arrangement can compensate for the deviation between the guide rail end cover 1 and the guide rail 2, so that the first connecting portion and the second connecting portion are easier to connect.

[0065] Furthermore, after the first connection part is connected to the second connection part, glue is injected into the connection between the first connection part and the second connection part to bond the first connection part and the second connection part, thereby further strengthening the connection between the guide rail end cover 1 and the guide rail 2. Bonding can also fill the connection gap and enhance the overall anti-vibration performance. This dual connection method can effectively resist potential loosening problems caused by environmental stress, temperature changes and long-term use, extend the service life of the components, simplify the production and assembly process, reduce dependence on precision machining tolerances, and improve production efficiency and consistency. The combination of multiple connection methods not only provides the necessary guarantee for high-intensity application scenarios, but also increases the durability and reliability of the structure, thereby improving the durability and user experience of the entire system. This improvement meets the needs for high-performance and high-reliability connections in practical applications.

[0066] Furthermore, the hard part 11 includes a first outer wall 119, which is provided as a part of the outer wall of the door assembly. The appearance characteristics of the first outer wall 119, such as color and glossiness, can be set to be similar to the appearance characteristics of the outer wall of the guide rail 2, or a decorative coating can be provided on the first outer wall 119, so that the appearance of the hard part 11 is similar to the appearance of the guide rail 2, thereby beautifying the appearance of the vehicle.

[0067] Furthermore, refer to Fig.12 In the prior art, when the guide rail end cover 1 made entirely of soft material is connected to the end of the guide rail 2, an abutting surface 4 is usually provided on the guide rail end cover 1, and the end of the guide rail 2 abuts against the abutting surface 4, and part of the guide rail end cover 1 protrudes relative to the outer wall of the guide rail 2, so that the guide rail end cover 1 is tightly connected to the guide rail 2 to prevent water leakage and air leakage at the end of the guide rail 2. This will affect the appearance of the vehicle. Fig.13 , and the first outer wall 119 of this embodiment is in the same plane as the outer wall of the guide rail 2, or when the outer wall of the guide rail 2 is coated with a coating such as paint, it is in the same plane as the first outer wall 119, so as to make the appearance of the vehicle more beautiful. At the same time, since the hard part 11 is made of hard material, this arrangement can also ensure the sealing effect of the port of the guide rail 2.

[0068] Reference Fig.14 A gap 13 is provided between the hard part 11 and the door frame 3, and this arrangement can prevent the hard part 11 from squeezing the film on the surface of the door frame 3 and causing the film to wrinkle. The soft part 12 is provided inside the door assembly, and the soft part 12 is attached to the inner wall of the door frame 3 to close the gap 13 between the hard part 11 and the door frame 3.

[0069] Furthermore, the connection structure between the soft part 12 and the door frame 3 and the elastic deformation property of the soft part 12 can compensate for the tolerance during the assembly process.

[0070] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
