Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a guide channel for automotive mirror door glass and a vehicle. Background Technology
[0002] Cars have become an indispensable means of transportation for modern people. Car windows are an important component of the whole vehicle, playing an important role in meeting the requirements of lighting, ventilation and visibility. Existing car windows are mainly of the type of lift windows. The windows are equipped with glass guide channels that slide with the door glass. The glass guide channels guide and seal the door glass, and the door glass can move up and down along the glass guide channels.
[0003] Due to limitations in space and angle, existing automotive door glass guide channels only comprise a small section between the upper and lower stops of the door frame, resulting in insufficient overall length. This causes uneven pressure on the edge of the door glass as it slides up and enters the guide channel, making the guide channel lip prone to warping, curling, or deformation. This further exacerbates friction and noise during the raising and lowering process, reducing the driving experience. Furthermore, it can lead to wear and tear, or even detachment, of the door glass after prolonged use, increasing safety hazards and affecting its lifespan.
[0004] Therefore, there is an urgent need for a car mirror door glass guide channel and vehicle to solve the above problems. Utility Model Content

[0034] like Figures 1 to 6As shown, this embodiment provides a car mirror door glass guide channel, which is installed on the car door frame and used to guide the lifting and lowering of the door glass 1. The car mirror door glass guide channel includes: a guide channel body 2 and a corner portion 3. The car door frame has a lower stop point, a transition point and an upper stop point along the direction from bottom to top. The guide channel body 2 is disposed between the transition point and the upper stop point. The guide channel body 2 has an inner lip, an outer lip and a supporting bottom. The supporting bottom is connected between the inner lip and the outer lip. The door glass 1 is disposed between the inner lip and the outer lip, and the door glass 1 can slide in contact with the inner lip and the outer lip. The corner portion 3 is disposed at the transition point, and the corner portion 3 can squeeze the guide channel body 2 so that the inner lip and the outer lip located at the transition point are disengaged from the door glass 1. With this configuration, the corner portion 3 presses against the guide groove body 2, causing the door glass 1 to separate from the inner and outer lips when it rises from the lower stop point to the transition point and just enters the guide groove body 2. This avoids uneven pressure on the door glass 1, which could cause the glass guide groove lip to curl or deform. It further reduces friction and noise during the lifting and lowering process of the door glass 1, effectively improves the smoothness of the lifting and lowering of the door glass 1, and extends its service life.
[0035] Optionally, the corner portion 3 is disposed on the outer side of the guide channel body 2 and protrudes from one end of the guide channel body 2. It should be noted that the corner portion 3 can create a gradient structure on the extrusion cross-section of the guide channel body 2.
[0036] Furthermore, the corner portion 3 and the guide groove body 2 are integrally formed. This configuration results in better structural stability of the integrally formed corner portion 3 and guide groove body 2, reduces the number of additional parts, lowers assembly complexity, and effectively improves production and processing efficiency.
[0037] Optionally, the door frame is provided with a guide rail along its length, and the guide groove body 2 is embedded in the guide rail. Specifically, the guide rail is U-shaped. This design can further prevent the door glass 1 from shifting, shaking, or getting stuck during the lifting and lowering process, ensuring its smoothness and reliability.
[0038] Optionally, in order to reduce the sliding friction resistance between the inner lip and the door glass 1 and reduce the power consumption of the electronic devices that drive the door glass 1 to rise and fall, the contact area between the inner lip and the door glass 1 is coated with a first coating, which is made of a low-friction material.
[0039] Optionally, in order to reduce the sliding friction resistance between the outer lip and the door glass 1, a second coating is applied to the contact area between the outer lip and the door glass 1. The second coating is made of a low-friction material.
[0040] In this embodiment, the first and second coatings can be PTFE (polytetrafluoroethylene) coatings, which are high-performance, low-friction, wear-resistant, and chemically resistant surface treatment materials. Of course, in other embodiments, the coating materials of the first and second coatings can be set according to actual needs, and no further limitations are imposed here.
[0041] Optionally, the guide channel body 2 is made of EPDM rubber. This design gives EPDM rubber excellent corrosion resistance and aging resistance, resulting in a long service life. It also absorbs vibrations from the door glass 1 and the door frame, reducing the risk of abnormal noise and ensuring structural stability and reliability. Of course, in other embodiments, the material used to make the guide channel body 2 can be chosen according to actual needs, and no further limitations are imposed here.
[0042] This embodiment also provides a vehicle, including a door frame and the automotive mirror door glass guide channel in the above solution, with the guide channel body 2 installed on the door frame.
[0043] Optionally, the vehicle also includes a front door fixed corner window 4, which is fixedly connected to the guide channel body 2. Further, the front door fixed corner window 4 and the guide channel body 2 are integrally formed.
[0044] It should be noted that the assembly process of the car mirror door glass guide channel in this embodiment is as follows: First, the guide channel body 2 is fixedly installed on the front door fixed corner window 4, and then the door glass 1 is raised from the lower stop point to the upper stop point and placed into the guide channel body 2.
[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
