Description

Technical Field

[0001] The invention belongs to the technical field of automobile accessories, in particular to an external water-cut assembly with unequal cross-sections. Background Art

[0002] The outer water cut of the car door is a rubber sealing strip in the groove at the bottom edge of the car door glass. It is mainly located on the outside of the car door, so it is called the outer water cut. The outer water cut of the car door is a rubber sealing strip in the groove at the bottom edge of the car door glass, which corresponds to the inner water cut of the car door (located inside the car door). Sealing function: When raising and lowering the car window glass, the outer water cut can effectively prevent rain, dust and other external impurities from entering the car, keeping the car environment clean and dry; Drainage function: The design of drainage holes and drainage pipes can quickly discharge the water accumulated inside the car door to the outside of the car, preventing water from being retained inside the car door and causing corrosion or damage.

[0003] The outer water cut of the car door is usually made of rubber material, which has a certain degree of elasticity and sealing. It may contain structures such as drainage holes and drainage pipes inside to drain water. When it rains or washes the car, water droplets will flow along the door glass to the outer water cut. The outer water cut prevents water from entering the car through its sealing performance and guides the water into the drainage pipe through the drainage holes. The drainage pipe guides the accumulated water along a predetermined path and discharges it to the outside of the vehicle, thereby keeping the door dry and clean.

[0004] With the optimized design of commercial vehicles, the lines of the water cut outside the car door will change accordingly to achieve a special-shaped design that is compatible with the edge of the lower frame of the window. In order to improve the side observation field of view, the lower frame of the commercial vehicle window will be designed in a stepped shape. In the prior art, rubber wipers are directly used for the water cut of windows with this structure, which lack external support, resulting in a lack of external protection and support for the wipers, which accelerates the aging of the wipers. Summary of the invention

[0005] In order to solve the problem that special-shaped water-cut parts lack external protection and support, the present invention provides an external water-cut assembly with unequal cross-sections.

[0006] The present invention is achieved through the following technical solutions: An external water-cut assembly of unequal cross-sections comprises an external water-cut shell, which is generally in a wavy structure with a lower front and a higher rear; an extrusion piece is embedded in the inner side of the external water-cut shell through a clamping assembly, and the extrusion piece is generally in an n-shaped structure, and at least two layers of cleaning pieces inclined upward are provided on the side of the extrusion piece away from the external water-cut shell.

[0007] The outer water-cut shell can form a conformal design with the lower frame of the car window, providing external support and protection for the extrusion with wiping function; the outer water-cut shell has a wavy shape with low front and high back, which can reduce the transition bending of the internal extrusion while improving its own structural strength, and help improve the wiping effect; the extrusion is embedded in the bent outer water-cut shell, which helps to improve the installation strength of the extrusion on the outer water-cut shell and improve the convenience of disassembly, assembly and replacement.

[0008] A further improvement of the present invention is that the front section of the outer water-cut shell is further provided with an outer support shell, the lower edge of which gradually decreases from the back to the front, and in the same cross section, the lower edge of the outer support shell is lower than the lower edge of the outer water-cut shell. The outer support shell helps to improve the structural strength of the lower part of the front section of the outer water-cut shell.

[0009] A further improvement of the present invention is that the gap between the outer support shell and the outer water-cut shell gradually increases from the back to the front.

[0010] A further improvement of the present invention is that a support sheet is provided between the outer support shell and the outer water-cut shell.

[0011] A further improvement of the present invention is that the above-mentioned clamping assembly includes upper clamping parts and lower clamping parts evenly distributed inside the outer water-cutting shell, and the upper clamping parts and the lower clamping parts are arranged in a staggered manner. The clamping parts arranged in a staggered manner increase the radiation area for fixing the extruded part.

[0012] A further improvement of the present invention is that the top surface of the extrusion is provided with a slot that can be matched with the upper clamp, and the extrusion is supported by the lower clamp near the lower edge of the outer water-cut shell. The extrusion is fixedly installed on the outer water-cut shell by cooperating with the upper clamp and the lower clamp.

[0013] A further improvement of the present invention is that a support frame is embedded inside the extrusion piece, which helps to strengthen the structural strength of the extrusion piece and prevent the extrusion piece from easily slipping out of the clamping assembly.

[0014] A further improvement of the present invention is that a downwardly inclined abutment sheet is provided on one side of the extrusion piece close to the outer water-cut shell. The abutment sheet and the inner wall support of the outer water-cut shell provide a reverse force for the extrusion piece, so that the extrusion piece is closely fitted in the clamping assembly, which helps to improve the installation strength of the extrusion piece on the outer water-cut shell and the water-scraping effect.

[0015] A further improvement of the present invention is that the inner groove of the extrusion piece is provided with at least two resilient support pieces, and the at least two resilient support pieces are arranged to be tilted upward as a whole. When the cleaning piece is in a squeezed state for wiping, the resilient support piece forms a support inside the n-shaped extrusion piece to ensure the adhesion between the external cleaning piece and the glass. A further improvement of the present invention is that the lower edge of the extrusion away from the outer water-cutting shell is provided with a flange bent toward the inner groove of the extrusion. When the cleaning sheet is in a squeezed state for wiping, the rebound support sheet forms a support inside the n-shaped extrusion to ensure the adhesion of the external cleaning sheet to the glass. This helps to provide support and reinforcement for the arrangement of the cleaning sheet on the extrusion.

[0016] It can be seen from the above technical scheme that the beneficial effects of the present invention are: the outer water-cut shell can form a conformal design with the lower frame of the vehicle window, providing external support and protection for the extrusion with wiping function; the outer water-cut shell has a wavy shape with low front and high back, which can reduce the transition bending of the internal extrusion while improving its own structural strength, and help improve the wiping effect; the extrusion is embedded in the bent outer water-cut shell, which helps to improve the installation strength of the extrusion on the outer water-cut shell and improve the convenience of disassembly, assembly and replacement.

[0025] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0026] like Figure 1-6 As shown, an external water cut assembly of unequal cross-sections includes an external water cut shell 1, and the external water cut shell 1 is an overall wave-shaped structure with a low front and a high back; it can not only improve the aesthetics, but also improve the structural strength of the external water cut shell 1. The front section of the external water cut shell is also provided with an external support shell 2, the lower edge of which gradually decreases from the back to the front, and in the same cross section, the lower edge of the external support shell 2 is lower than the lower edge of the external water cut shell 1, and the gap between the external support shell 2 and the external water cut shell 1 gradually increases from the back to the front; a support sheet 3 is provided between the external support shell 2 and the external water cut shell 1. Since the front section of the external water cut shell 1 is a low-lying section, the external support shell 2 can improve the torsional strength of the front section of the external water cut shell 1 when it is squeezed by the glass lifting.

[0027] The extrusion piece 4 is an n-shaped structure as a whole, and a support frame 5 is embedded inside the extrusion piece 4; a support is formed inside the extrusion piece 4. The side of the extrusion piece 4 away from the outer water-cut shell 1 is provided with at least two layers of cleaning pieces 8 inclined upward; used to scrape water drops on the outer wall of the glass when it is raised or lowered. The side of the extrusion piece 4 close to the outer water-cut shell 1 is provided with a downwardly inclined abutment piece 6; the inner groove of the extrusion piece 4 is provided with at least two rebound support pieces 7, and at least two rebound support pieces 7 are arranged upwardly inclined as a whole; when the extrusion piece 4 is squeezed and deformed, the rebound support piece 7 can serve as a support to reduce the deformation amplitude of the extrusion piece 4. The lower edge of the extrusion piece 4 away from the outer water-cut shell 1 is provided with a flange bent toward the inner groove of the extrusion piece 4; since the side of the extrusion piece 4 away from the outer water-cut shell 1 is longer, the flange enhances the structural strength of the longer side.

[0028] The inner side of the outer water-cut housing 1 is embedded with an extrusion 4 through a clamping assembly, and the clamping assembly includes an upper clamp 9 and a lower clamp 10 evenly distributed on the inner side of the outer water-cut housing 1, and the upper clamp 9 and the lower clamp 10 are arranged in a staggered manner. The top surface of the extrusion 4 is provided with a clamping groove that can be matched with the upper clamp 9, and the extrusion 4 is supported by the lower clamp 10 near the lower edge of the outer water-cut housing 1; the lower clamp 10 is inclined toward one side of the extrusion 4 and upward, and the lower section of the extrusion 4 near the outer water-cut housing 1 is parallel to the lower clamp 10 as a whole. It is convenient for the extrusion 4 to be quickly assembled into one with the outer water-cut housing 1.

[0029] The present invention describes an external water-cut assembly with unequal cross-sections, in which the external water-cut shell can form a conformal design with the lower frame of the vehicle window, providing external support and protection for the extrusion with a wiping function; the external water-cut shell has a wavy shape with a low front and a high rear, which can reduce the transition bending of the extrusion inside it while improving its own structural strength, and help improve the wiping effect; the extrusion is embedded in the bent external water-cut shell, which helps to improve the installation strength of the extrusion on the external water-cut shell and improves the operational convenience of disassembly, assembly and replacement.
