Detailed Description
The making and using of the embodiments are discussed in detail below. It should be understood, however, that the detailed description and the specific examples, while indicating specific ways of making and using the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention. The structural position of the various components as described, such as the directions of up, down, top, bottom, etc., is not absolute, but rather relative. When the individual components are arranged as shown in the figures, these directional expressions are appropriate, but when the position of the individual components in the figures changes, these directional expressions also change accordingly.
Herein, unless specifically stated and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly. For example, the two parts can be fixedly connected, detachably connected or integrated; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the terms herein above will be understood by those skilled in the art as the case may be.
Herein, "outer" and "inner" are relative to the inside and outside of the vehicle, "outer" refers to a direction toward the outside of the vehicle, and "inner" refers to a direction toward the inside of the vehicle.
Typically, the out-of-window trim includes an integral structural member to be attached to both the body sheet metal (e.g., door sheet metal) and the window glass, thereby functioning as a seal. Due to the complex structure, difficult machining, difficult disassembly or replacement, etc., more and more outside window water cuts employ a combination of the outer body 30 and the lip 40 and connect the two to each other, for example, by ultrasonic welding. As shown in fig. 2A to 4C, the outer body 30 includes an outer garnish 31 and a first connecting portion 32 formed by a double injection molding process, wherein the first connecting portion 32 is provided with a welding portion 33 protruding toward the inside. The lip 40 includes an abutment lip 41 adapted to contact the window glass, and a second connecting portion 42 corresponding to the first connecting portion 32, the second connecting portion 42 and the welded portion 33 on the first connecting portion 32 being welded to each other when the outer body 30 and the lip 40 are connected.
It has been appreciated that although the attachment of the lip 40 to the window glass and the attachment of the outer body 30 to the body panel work together for achieving the effects of leakage prevention, sound insulation, dust prevention, shock absorption and sealing, the welded portions 33 formed on the first connecting portion 32 are not continuous structures due to the limitation of the welding process, as shown in fig. 2A and 2B, so as to be suitable for performing welded connection at the respective welded portions 33 by, for example, a welding gun. Although the distances between the welded parts are different based on different vehicle types, since there is a certain distance between the adjacent welded parts 33, the adhesion between the outer body 30 and the lip 40 is weaker than that of the region connected by the welded parts for the region where there is no welded part, thereby forming an assembly gap, so that air or water easily enters the region where there is no welded part inside the door during running or washing of the vehicle, as shown by an arrow in fig. 4C, thereby causing problems such as water leakage or vibration noise.
The present invention thus proposes an improved out-of-window water cut by varying the lip configuration so that after the lip is attached to the outer body 30, a complete seal is formed therebetween. It should be understood that while the invention is described based on the outer body and lip shown in fig. 2A-4C, the construction shown is not meant to be prior art.
Referring specifically to one embodiment shown in fig. 5A and 5B, the lip 50 of the present invention includes an abutment lip 51 adapted to contact the window glass, and a second connection 52 corresponding to the first connection 32. In addition, the lip 50 includes a sealing portion 53 that mates with the outer body for enabling the sealing portion 53 to closely contact the first connection portion 32 to seal all contact areas with the first connection portion 32 when the lip 50 is connected with the outer body 30.
Advantageously, the sealing portion 53 is configured as a sealing lip disposed along the entire length of the lip 50, as shown in fig. 5A. In the illustrated preferred embodiment, the sealing portion 53 is disposed between the abutment lip 51 and the second connecting portion 52, as shown in fig. 5B. In this way, when the lip 50 is still welded to the outer body 30, both in the region of the weld 33 of the first connection portion 32 of the outer body 30 shown in fig. 6A and in the region of the non-weld 33 shown in fig. 6B, the sealing portion 53 of the lip 50 can be maintained in sealing contact with the first connection portion 32, completely avoiding the gap between the two flows of outside air or water.
It should be appreciated that the first connection portion 32 of the outer body 30, which serves as a structural support for the lip 50, should have sufficient structural strength or rigidity and may be of a different material than the outer trim piece 31. For example, the outer decorative member 31 may be a thermoplastic elastomer (TPE) having a certain flexibility and securing an external beauty, and the first connecting portion 32 may be polypropylene (PP) having a certain hardness and being adapted to be welded. Similarly, the abutment lip 51 of the lip 50 may likewise be TPE to ensure a tight fit with the glazing to ensure tightness, and the second connection 52 may be PP to ensure connection strength. The weld 33 may be integrally formed, such as by extrusion, at the lower end of the lip adjacent the second connecting portion 52 by an injection molding process. Also, since the hardness of the first connection portion 32 is greater than that of the sealing portion 53, after the lip 50 is connected to the outer body 30, the sealing portion 53 can be deformed to be tightly fitted or over-fitted with the first connection portion 32, thereby better filling the fitting gap therebetween and ensuring the sealing effect.
Fig. 7 shows a schematic cross-sectional view of the application of the out-of-window water cut of the present invention to a window glass. The outer body 30 is adapted to be connected to the body panel 60, and a tongue 34 may be provided at the lower end of the outer garnish 31 to abut against the body panel 60 to improve the sealing property. The lip 50 is adapted to abut against the window pane 20 and may be provided with a scraping portion 54, such as a nap, to scrape the pane from foreign matter as the window pane is lifted. The extra-window water cut of the present invention achieves a complete seal by forming the sealing portion 53 in the form of a lip on the lip 50, prevents air or water from entering due to the gap formed between the outer body 30 and the lip 50, and improves reliability and NVH performance of the extra-window water cut. The sealing part is simple in design and easy to implement, a new process is not needed to be added, and the external main body is not needed to be structurally changed, so that the cost is saved, the sealing part can be suitable for various external water cuts, and the application is wide.
It should be understood herein that the embodiments shown in the drawings show only alternative shapes, sizes and arrangements of the outside water cuts of the vehicle window according to the present invention, which are however illustrative only and not limiting, other shapes, sizes and arrangements may be adopted without departing from the spirit and scope of the present invention.
While the foregoing has described the technical content and features of the present invention, it will be appreciated that those skilled in the art, upon attaining the teachings of the present invention, may make variations and improvements to the concepts disclosed herein, which fall within the scope of the present invention. The above description of embodiments is illustrative and not restrictive, and the scope of the invention is defined by the claims.
