Description

Technical Field

[0001] This utility model belongs to the field of automotive body parts, specifically relating to a concealed door outer clip assembly, a door, and a vehicle. Background Technology

[0002] The exterior door trim assembly is a key functional component of the door system, providing support, clamping, and sealing for the window operation, while also serving a decorative purpose. Traditional exterior door trim is typically installed on the outer edge of the door panel, with a portion of its structure exposed beyond the panel, and a significant visible area. This necessitates careful consideration of the trim's impact on the overall vehicle appearance during the design process, increasing the complexity of the body design and resulting in additional manpower and material costs.

[0003] In recent years, with the continuous evolution of vehicle body styling, design requirements have gradually shifted towards minimizing and narrowing the visible surface of the door exterior trim assembly, even concealing most of its structure inside the door. This effectively reduces the surface difference between the trim assembly and the door glass surface, placing it in an invisible area to the greatest extent possible; especially when the concealed door exterior trim assembly is applied to frameless doors, it can further enhance the overall visual quality of the vehicle's appearance. However, existing concealed door exterior trim assemblies generally suffer from insufficient installation stability, and are prone to loosening or even detachment during use. Utility Model Content

[0004] The purpose of this invention is to provide a concealed door external clamping strip assembly, door, and vehicle to improve their installation stability.

[0005] In a first aspect, this utility model provides a concealed door outer clamping strip assembly, which includes: an outer clamping strip body, an outer clamping strip lower lip, a mounting clip, an outer clamping strip upper lip, and a steel strip; the steel strip is embedded in the outer clamping strip body to support the outer clamping strip body, the outer top of the outer side of the outer clamping strip body protrudes outward to form a boss that can fit against the snap-fit ​​edge of the outer door panel, the outer clamping strip upper lip is located on the upper inner side of the outer clamping strip body and can fit tightly against the outer side of the door glass, the outer clamping strip lower lip is located on the lower inner side of the outer clamping strip body and can fit tightly against the outer side of the door glass, the bottom of the mounting clip body is bent inward and extended upward to form a slot, the bottom of the mounting clip body is bent outward to form a lower limit locking foot, the outer side of the mounting clip has an upper limit locking block, the bottom of the outer clamping strip body is inserted into the slot and engaged with the mounting clip, and the mounting clip can be engaged with the reinforcing member on the outer door panel through the upper limit locking block and the lower limit locking foot.

[0006] Preferably, the inner side of the mounting clip and the outer side of the outer clamping strip body are bonded together with adhesive. This surface-contact adhesive bonding method, compared to a connection using only a snap-fit ​​method, further enhances the stability of the connection between the mounting clip and the outer clamping strip body, preventing loosening and detachment.

[0007] Preferably, the lower part of the outer clamping strip body has a limiting step, and the end of the slot has a barb. When the bottom of the outer clamping strip body is inserted into the slot, the limiting step and the barb engage and limit the movement, making assembly simple and quick.

[0008] Preferably, the upper limit stop block is T-shaped and has a stop bar perpendicular to the main body and a limiting plate parallel to the main body, which helps to improve the firmness of the connection between the mounting clip and the reinforcing member on the outer panel of the door.

[0009] Preferably, the upper limit stop block can engage with the T-shaped hole on the reinforcement of the outer door panel for X-axis and Y-axis limiting; the lower limit stop pin can engage with the upper edge of the straight hole on the reinforcement of the outer door panel for Z-axis limiting. By using the upper limit stop block and the lower limit stop pin to cooperate with the T-shaped hole and the straight hole respectively, the concealed outer door trim assembly can be precisely positioned in the X, Y, and Z directions, improving assembly efficiency and stability.

[0010] Preferably, the height of the retaining strip along the inward and outward directions is slightly greater than the depth of the T-shaped hole along the inward and outward directions. The retaining strip can be engaged within the vertical portion of the T-shaped hole, allowing the limiting plate to fit and limit the outer side of the reinforcement on the outer door panel, and allowing the main body to fit and limit the inner side of the reinforcement on the outer door panel. The retaining strip engaging within the vertical portion of the T-shaped hole forces the limiting plate to fit tightly against the outer side of the reinforcement on the outer door panel, eliminating assembly gaps and improving X and Y direction positioning accuracy and vibration resistance.

[0011] Preferably, the outer clamping strip body is made of PVC, the steel strip is made of stainless steel, and the outer clamping strip body and the steel strip are co-extruded together by injection molding.

[0012] Preferably, the mounting clip is made of PA6+15% glass fiber.

[0013] Secondly, this utility model provides a car door, including an outer door panel, a reinforcing member on the outer door panel, an outer clamping strip assembly, a door glass, a door interior panel, an inner clamping strip assembly, an inner door panel, and a reinforcing member on the inner door panel; the reinforcing member on the outer door panel is connected to the outer door panel, the outer clamping strip assembly is snapped onto the reinforcing member on the outer door panel and is tightly attached to the upper edge of the outer door panel and the outer side of the door glass, the reinforcing member on the inner door panel is connected to the inner door panel, the inner clamping strip assembly is snapped onto the upper edge of the inner door panel and the reinforcing member on the inner door panel and is tightly attached to the inner side of the door glass, and the door interior panel covers the inner door panel, the reinforcing member on the inner door panel, and the inner clamping strip assembly; the outer clamping strip assembly adopts the above-mentioned concealed door outer clamping strip assembly.

[0014] Thirdly, this utility model provides a vehicle that includes the aforementioned door.

[0015] This utility model has the following effects: (1) The steel strip embedded in the outer clamp strip body can provide rigid support, ensuring that the outer clamp strip maintains the preset shape after long-term use, avoiding sealing failure or loose assembly due to deformation; and the supporting effect of the steel strip can make the outer clamp strip body fit more stably against the car door outer panel and car door glass, reducing abnormal noise or sealing gap caused by deformation of the outer clamp strip body.

[0016] (2) The lower lip and upper lip of the outer clamp strip can fit tightly against the outside of the door glass to form an elastic fit structure. No matter where the door glass is raised or lowered, the two lips can tightly wrap the outside of the door glass, which not only prevents rainwater, dust and sand from seeping into the door from the gap between the door glass and the outer clamp strip, but also plays a buffering role when the door glass is raised or lowered, reducing the friction noise between the door glass and the outer clamp strip. The protrusion on the top of the outer side of the outer clamp strip body can fit with the snap-fit ​​edge of the door panel, filling the assembly gap between the outer clamp strip body and the door panel, further blocking the entry of external airflow and moisture, and at the same time enhancing the integrated look of the door.

[0017] (3) The outer clamping strip body is inserted into the bottom slot and connected to the mounting clip. The mounting clip is then connected to the door outer panel reinforcement through the upper limit block and the lower limit foot. The entire process does not require complex connection methods such as bolts and welding, which greatly shortens the production line time and reduces the assembly cost. The upper limit block (limiting the upward displacement of the mounting clip) and the lower limit foot (limiting the downward displacement of the mounting clip) form a two-way limit. Combined with the slot to fix the clamping strip body, the installation stability is improved. It can effectively prevent the clamping strip from loosening or falling off due to vibration during vehicle operation, and ensure long-term assembly reliability. Attached Figure Description
