Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a novel window frame decorative strip, a decorative strip structure, an automobile, and an installation method. Background Technology

[0002] Currently, the decorative strips installed on the exterior of car doors in the industry are often co-extruded from stainless steel and soft PVC, forming a "C"-shaped installation structure. This installation structure can only be used for rolled window frame doors and cannot be used for one-piece stamped doors. Furthermore, conventional window frame trim strips are attached with tape, which results in unreliable fixing.

[0003] Meanwhile, with the continuous development of the automotive industry, people are no longer only focusing on the basic performance of cars, but also have increasingly higher requirements for their appearance. However, conventional composite co-extruded bright strips cannot undergo post-processing surface treatment and cannot meet users' needs for color diversity.

[0004] Therefore, there is a need to provide a new type of window frame trim strip that satisfies the assembly firmness of integral stamped doors and offers users a wider range of color options to solve the aforementioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a novel window frame decorative strip. It solves the technical issues of existing window frame decorative strips, such as the unreliable use of adhesive tape for adhesion, the inability to perform subsequent surface treatments on conventional composite co-extruded bright strips, and the inability to meet users' demands for diverse colors.

[0006] The technical effects of this invention are achieved through the following:

[0007] A novel window frame trim strip, for installation on a one-piece stamped car door, includes a window frame trim strip body and a window frame bright strip. The window frame trim strip body includes a side wall and a mounting portion with mounting holes. The side wall and the mounting portion are at a preset angle. A fixing member is provided on the outer panel of the one-piece stamped car door. The window frame trim strip body is fixed to the mounting portion on the fixing member through the mounting member. The side wall near the mounting portion and away from the mounting portion have corresponding protrusions of a first adhesive body and a second adhesive body. The window frame bright strip is snapped onto the first adhesive body and the second adhesive body. The window frame trim strip body and the outer panel of the car door form a guide groove structure for the glass groove to snap into the guide groove structure. By separating the window frame bright strip and the window frame trim strip body, the window frame bright strip can be pre-painted and then snapped together for fixation, meeting users' needs for different colors and solving the problem that conventional C-shaped window frame trim strips in the prior art cannot undergo post-processing surface treatment. By using a window frame trim body with sidewalls and mounting parts at a preset angle, the window frame trim body and the outer door panel form a guide channel structure, providing a hook structure for the glass groove, thereby replacing conventional guide rails, making the overall window frame trim structure simpler, easier to implement, and cost-saving.

[0008] Furthermore, the fastener is a nut seat, which is snapped and fixed to the outer panel of the car door, and the mounting component is a screw.

[0009] Furthermore, the fixing component is a screw, which is riveted to the outer door panel, and the mounting component is a nut. Mounting holes are provided in the mounting section, and the window frame trim body is stably fixed to the outer door panel by screwing the mounting component and the fixing component together. This solves the problem of using tape to stick the window frame trim to the outer door panel and effectively prevents the window frame trim from aging and falling off.

[0010] Furthermore, the first adhesive and the outer door panel are interference-fitted. By configuring the first adhesive and the outer door panel with an interference fit, the window frame trim strip can be effectively waterproofed, providing a good sealing effect.

[0011] Furthermore, the length of the sidewall in the extending direction is greater than the length of the mounting portion in the extending direction, and the end of the sidewall that extends beyond the mounting portion is snapped onto the outer panel of the door by a snap-fit ​​member.

[0012] By providing a snap-fit ​​component at the end of the side wall, the end of the side wall can be snapped onto the outer panel of the door, thus fixing the end to the outer panel and effectively preventing the end from lifting up.

[0013] Furthermore, the window frame trim body, the first adhesive, and the second adhesive are an integrated structure, which is manufactured using a composite co-extrusion molding process.

[0014] In addition, a novel window frame trim structure is provided, including an outer door panel, a door glass, a glass groove, and the aforementioned novel window frame trim. The novel window frame trim is screwed and fixed to the outer door panel, and the glass groove is engaged in the guide groove structure formed by the window frame trim body and the outer door panel.

[0015] In addition, an automobile is provided that includes the aforementioned novel window frame trim structure.

[0016] In addition, a novel method for installing window frame decorative strips is provided, the method being implemented based on the aforementioned novel window frame decorative strip, the method comprising:

[0017] The window frame trim body, the first adhesive, and the second adhesive are processed into an integrated structure using a composite co-extrusion molding process;

[0018] The window frame bright strip is snapped onto the first adhesive and the second adhesive to fix the window frame bright strip onto the window frame trim body;

[0019] Pass the mounting or fastening parts through the mounting holes and complete the fixed connection between the mounting and fastening parts to fix the window frame trim body to the outer door panel, while completing the interference fit between the first adhesive and the outer door panel.

[0020] Further, the window frame bright strip is snapped onto the first adhesive and the second adhesive to fix the window frame bright strip to the window frame trim body, which includes the following steps:

[0021] Obtain the user's color customization requirements;

[0022] The surface of the window frame bright strip is sprayed according to the color customization requirements to obtain a window frame bright strip that meets the user's color customization needs.

[0023] As described above, the present invention has the following beneficial effects:

[0024] 1) Mounting holes are provided in the mounting section. The window frame trim is fixed to the outer door panel more stably by screwing the mounting parts and the fasteners together. This solves the problem of using tape to stick the window frame trim to the outer door panel and effectively avoids the problem of the window frame trim aging and falling off.

[0025] 2) By separating the window frame bright strip and the window frame trim body, the window frame bright strip can be sprayed first and then snapped together to complete the fixation, which can meet the user's needs for different colors and solve the problem that conventional C-shaped window frame trim cannot be surface treated in the later process in the existing technology.

[0026] 3) By providing a window frame trim body with sidewalls and mounting parts at a preset angle, the window frame trim body and the outer door panel form a guide channel structure, providing a hanging structure for the glass groove, thereby replacing the conventional guide rail, making the overall window frame trim structure simpler, easier to implement, and cost-saving.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] Example 1:

[0038] like Figure 1 and Figure 2 As shown in the embodiment of this specification, a novel window frame decorative strip is provided for installation on an integral stamped car door. It includes a window frame decorative strip body 1 and a window frame bright strip 2. The window frame decorative strip body 1 includes a side wall 11 and a mounting part 12 with mounting holes 121. The side wall 11 and the mounting part 12 are at a preset angle. A fastener 4 is provided on the outer panel 3 of the integral stamped car door. The window frame decorative strip body 1 is fixed to the mounting part 12 on the fastener 4 by the mounting part 5. The side wall 11 has a first adhesive body 13 and a second adhesive body 14 protruding one to one on the side near the mounting part 12 and the side away from the mounting part 12, respectively. The window frame bright strip 2 is snapped onto the first adhesive body 13 and the second adhesive body 14. The window frame decorative strip body 1 and the outer panel 3 of the car door form a guide groove structure for the glass groove 7 to be snapped into the guide groove structure.

[0039] It should be noted that, as Figure 3 As shown, the conventional C-shaped window frame trim 10 in the prior art is an integrated trim, and the color of the outer surface 101 of the C-shaped window frame trim is the same as the color of the C-shaped window frame trim. When customers request different colors, because the C-shaped window frame trim needs to have a sealing function, there is an adhesive 102 on the outer surface 101 of the C-shaped window frame trim. Therefore, when spraying color onto the outer surface 101, the area of ​​the adhesive 102 needs to be covered before spraying can be carried out. However, in actual operation, it cannot be guaranteed that while the adhesive 102 is covered, the area of ​​the outer surface 101 not covered by the adhesive 102 can be fully sprayed.

[0040] Therefore, by separating the window frame bright strip 2 and the window frame trim body 1, this application allows the window frame bright strip 2 to be painted first, and then snapped together to fix the window frame bright strip 2 and the window frame trim body 1, thus meeting the user's needs for different colors and solving the problem that conventional C-shaped window frame trims in the prior art cannot undergo post-process surface treatment.

[0041] Specifically, such as Figure 1 As shown, the preset angle is 80 to 120 degrees, preferably 90 degrees. The side wall 11 and the mounting part 12 form an L-shaped structure. The L-shaped structure and the outer door panel 3 together form a Z-shaped structure, that is, a guide groove structure, which is used for the glass groove 7 to be engaged in it.

[0042] Specifically, the window frame trim body 1 is made of stainless steel.

[0043] In this embodiment, the fixing component 4 is a nut seat, which is snapped and fixed to the outer door panel 3, and the mounting component 5 is a screw. After the screw passes through the mounting hole 121, it is screwed into the nut seat to complete the connection, thereby fixing the window frame trim body 1 to the outer door panel 3.

[0044] In some other embodiments, the fastener 4 is a screw, which is riveted to the outer door panel 3, and the mounting element 5 is a nut. The mounting hole 121 of the window frame trim body 1 is passed through the screw, and then the nut is used to complete the screw connection with the screw, thereby fixing the window frame trim body 1 to the outer door panel 3.

[0045] It should be noted that, as Figure 3 As shown, the installation process of the conventional C-shaped window frame trim 10 includes: hooking the upper and lower clips of the C-shaped window frame trim 10 onto the vertically positioned clips 81 on the rolled door 8; and attaching the middle area of ​​the C-shaped window frame trim 10 to the corresponding position on the rolled door 8 using tape 15. After installing the C-shaped window frame trim 10, a guide rail 9 with a Z-shaped structure is installed at the lower position of the rolled door 8, and then the glass groove is installed in the guide rail 9.

[0046] In this application, the nut seat is pre-installed on the outer door panel 3, and then self-tapping screws are passed through the mounting holes 121 of the window frame trim body 1 and locked to the outer door panel 3. Therefore, by providing mounting holes 121 in the mounting part 12, and screwing the mounting part 5 and the fixing part 4 together, the window frame trim body 1 is more stably fixed to the outer door panel 3, solving the problem of using tape to stick the window frame trim to the outer door panel and effectively avoiding the problem of aging and falling off the window frame trim. By providing a side wall 11 with a preset angle and a mounting part 12, the window frame trim body 1 and the outer door panel 3 form a guide groove structure, providing a hanging structure for the glass groove 7, thereby replacing the conventional guide rail, making the overall window frame trim structure simpler, easier to implement, and cost-effective.

[0047] Preferably, the first colloid 13 and the outer door panel 3 are interference-fitted.

[0048] Specifically, such as Figure 1As shown, the L-shaped structure formed by the side wall 11 and the mounting part 12 is not a standard L-shaped structure, but only close to an L-shape. The connection position between the side wall 11 and the mounting part 12 is upwardly protruding, causing the first adhesive 13 located at the connection position to protrude upwards. After the window frame bright strip 2 is engaged with the first adhesive 13 and the second adhesive 14, the first adhesive 13 wraps around the upper end of the window frame bright strip 2. The window frame bright strip 2 is engaged with the window frame trim body 1 through the second adhesive 14 and the portion of the first adhesive 13 located inside the window frame bright strip 2. The portion of the first adhesive 13 located outside the window frame bright strip 2 is tightly abutted against the outer door panel 3, completing the interference fit with the outer door panel 3.

[0049] Specifically, the first colloid 13 and the second colloid 14 are made of TPV material.

[0050] Specifically, the first colloid 13 and the second colloid 14 can be an integrated colloid, and the thickness of the integrated colloid is uniformly distributed at the middle position of the window frame bright strip 2.

[0051] Preferably, the length of the side wall 11 in the extending direction is greater than the length of the mounting part 12 in the extending direction. The outer door panel 3 is provided with an opening. The end of the side wall 11 that extends beyond the mounting part 12 is snapped into the opening at the corresponding position on the outer door panel 3 by a snap-fit ​​member 111.

[0052] Specifically, such as Figure 2 As shown, the window frame trim body 1 has four mounting positions, including three mounting holes 121 and a snap-fit ​​piece 111. The window frame trim body 1 and the outer door panel 3 are fixed through these four mounting positions.

[0053] Preferably, the window frame trim body 1, the first colloid 13, and the second colloid 14 are an integrated structure, which is processed by a composite co-extrusion molding process.

[0054] like Figure 3 As shown in the figure, this specification provides a novel window frame decorative strip installation method, which is based on the novel window frame decorative strip in Embodiment 1, and includes the following steps:

[0055] S100: The window frame trim body 1, the first colloid 13, and the second colloid 14 are processed into an integrated structure using a composite co-extrusion molding process;

[0056] S200: Attach the window frame bright strip 2 to the first adhesive 13 and the second adhesive 14 to fix the window frame bright strip 2 to the window frame trim body 1;

[0057] S300: Pass the mounting part 5 or the fastener 4 through the mounting hole 121 and complete the fixed connection between the mounting part 5 and the fastener 4 to fix the window frame trim body 1 to the outer door panel 3, and at the same time complete the interference fit between the first adhesive 13 and the outer door panel 3.

[0058] It should be noted that steps S200 and S300 can also be interchanged, that is, the window frame trim body 1 can be fixed first, and then the window frame bright strip 2 can be snapped on.

[0059] like Figure 4 As shown, in one specific embodiment, step S300 involves snapping the window frame bright strip 2 onto the first adhesive 13 and the second adhesive 14 to fix the window frame bright strip 2 onto the window frame trim body 1. Prior to this step, the following steps are included:

[0060] S401: Obtain the user's color customization requirements;

[0061] S402: Spray paint the surface of the window frame bright strip 2 according to the color customization requirements to obtain the window frame bright strip 2 that meets the user's color customization requirements.

[0062] Furthermore, after the car is delivered, if the user needs to change the color of the window frame bright strip 2, there is no need to remove the window frame trim body 1. The window frame bright strip 2 can be replaced directly. The process of changing the color of the new window frame trim is simpler and helps to improve the user experience.

[0063] Example 2:

[0064] This specification provides a novel window frame trim structure, including a door outer panel 3, a door glass 6, a glass groove 7, and the novel window frame trim strip in Embodiment 1. The novel window frame trim strip is screwed and fixed to the door outer panel 3, and the glass groove 7 is snapped into the guide groove structure formed by the window frame trim strip body 1 and the door outer panel 3.
