[0026] like Figure 1As shown, the zero-order difference structure of the door glass is used to manufacture various automobile door frames, mainly including an inner panel 100, an outer panel 200, a glass component and a window frame groove 202. Here, the inner panel 100 and the outer panel 200 can be formed and assembled in a variety of ways such as rolling or stamping. The outer panel 200 is located on the upper part of the inner panel 100, wherein the inner panel 100 and the outer panel 200 extend horizontally and are connected into a whole to form a door frame body. The door frame body is hollow inside, so that the overall weight of the door can be reduced while ensuring strength. The upper surface of the outer panel 200 has an outer decorative cover plate 800, which can be connected by pasting or locking, and is mainly used for covering up and sealing. , preventing the outer panel 200 from being directly exposed to the outside, the glass assembly includes a guide assembly 300 and a glass piece 400, wherein the lower end of the glass piece 400 is connected to the guide assembly 300, and the window frame groove 202 in this embodiment is formed by bending the left side of the outer panel 200 and is used to install the guide assembly 300, and the glass piece 400 is located at the upper part outside the window frame groove 202, and the guide assembly 300 drives the glass piece 400 to rise and fall while making the glass piece 400 flush with the surface of the outer decorative cover plate 800. The main innovation of this patent here is to make the glass piece 400 flush with the surface of the outer decorative cover plate 800, thereby achieving a low step difference between the glass piece 400, the window frame groove 202 and the outer decorative cover plate 800, thereby reducing the wind resistance of the vehicle movement and improving the vehicle comfort.

[0027] In order to facilitate installation with the side body inside the car, the inner panel body 100 has an inner support part 101 extending to the left side, and a plastic protective part 103 is adhered to the outer bottom surface of the inner support part 101. A vehicle side seal 102 is installed on the right side surface of the inner panel body 100. The plastic protective part 103 can be used to protect the outer bottom surface of the inner support part 101, and the vehicle side seal 102 can improve the sealing performance.

[0028] Here, when the glass member 400 and the guide assembly 300 are raised and lowered, it is necessary to limit the movement of the door glass in the front and rear directions of the vehicle and in and out of the vehicle in order to achieve smooth raising and lowering, and good sealing performance must be considered. Specifically, Figure 2 As shown, the guide assembly 300 includes a guide member 600 and an auxiliary mud trough 700. A connecting member 401 is provided between the guide member 600 and the lower end plane of the glass member 400. In this way, the glass member 400 and the guide member 600 are formed into a whole by using the connecting member 401. The guide member 600 is U-shaped as a whole and has a U-shaped groove 601. Since the guide member 600 is located in the window frame groove 202, it is necessary to limit and seal each position of the guide member 600 to ensure the stability of lifting and lowering.

[0029] The auxiliary mud groove 700 is nested in the U-shaped groove 601 and maintains a seal with both sides of the U-shaped groove 601. In this embodiment, as an optimization, a plurality of protrusions 701 are distributed on the left side of the auxiliary mud groove 700, and a first lip edge 702 and a second lip edge 703 are respectively integrally connected to the right side and the lower side of the auxiliary mud groove 700. The protrusions 701, the first lip edge 702 and the second lip edge 703 are respectively in contact with the left, right and lower sides of the guide member 600, wherein a rest adjustment lip 704 is integrally connected to the upper end of the auxiliary mud groove 700, and the rest adjustment lip 704 is rested on the right end of the glass member 400 and is used to close the gap 705 formed between the glass member 400 and the outer decorative cover plate 800. The protrusions 701, the first lip edge 702 and the second lip edge 703 can ensure the position and sealing of the guide member 600, and the rest adjustment lip 704 can ensure the sealing of the end of the glass member 400 and prevent impurities from falling into the inside, affecting the overall lifting and lowering.

[0030] In order to fix and limit the position of the auxiliary mud trough 700, as an optimization, a positioning groove 706 is provided on the auxiliary mud trough 700, and a limiting member 500 extending toward the side of the outer plate body 200 and fixedly connected to the outer plate body 200 is installed on the positioning groove 706. A support member 501 is also integrally connected to the limiting member 500, and the support member 501 is supported on the bottom of the outer decorative cover plate 800, so as to ensure the assembly stability of the outer decorative cover plate 800 and the appearance effect.

[0031] A locking piece 502 is provided on the limiting piece 500. As an optimization, the outer plate 200 is bent toward the locking piece 502 to form a locking platform 201. The locking piece 502 passes through the limiting piece 500 and the locking platform 201. A retaining spring 503 is provided at the bottom of the locking platform 201. The locking piece 502 and the retaining spring 503 fasten the limiting piece 500 and the auxiliary mud groove 700 into one, and realize the lifting and lowering of the glass piece 400 and the guide piece 600. In this embodiment, the matching method of the retaining spring 503 and the locking piece 502 is adopted. In the event of damage, the guide member 600 and the glass member 400 can be disassembled and replaced more conveniently. Since the limiting member 500 is locked together by the locking member 502, the retaining spring 503 and the outer plate 200, this is equivalent to fixing the position of the limiting member 500. Since the limiting member 500 is connected to the auxiliary mud groove 700 through the positioning groove 706, the position of the auxiliary mud groove 700 is also fixed, thereby facilitating the subsequent cooperation of the guiding member 600 therewith and ensuring the limiting position and sealing performance of the guide line lifting and lowering.

[0032] In order to seal and limit the left side position of the guide member 600, as an optimization, the inner plate body 100 is integrally extended to the left with an inner support portion 101, wherein an end fitting portion 104 is provided between the left end of the inner plate body 100 and the left end of the outer plate body 200, and a retaining sealing strip 900 is provided on the end fitting portion 104. Figure 3 As shown, the sealing strip 900 includes an integrally formed sleeve portion 901, an upper supporting portion 902, a fitting portion 903 and a retaining lip 904, wherein the sleeve portion 901 is sleeved on the end matching portion 104 for overall fixation, the upper supporting portion 902 is located at the upper end of the sleeve portion 901 and is attached to the bottom of the glass member 400, the fitting portion 903 extends to the lower right and is attached to the lower bottom surface of the window frame groove 202, the retaining lip 904 is located on the right side of the sleeve portion 901 and contacts and cooperates with the left side of the guide member 600, wherein the left end of the plastic protective member 103 is inserted into the end formed by the upper supporting portion 902 and the sleeve portion 901 The upper supporting portion 902 is used to ensure the stability of the glass component 400, and the fitting portion 903 can prevent the bottom of the guide component 600 from being scratched during movement, thereby protecting the center column. The lip 904 can ensure the left position and sealing of the guide component 600. The above structure limits the movement of the door glass in the front and rear directions, inside and outside directions of the vehicle, reduces the step difference among the glass component 400, the outer decorative cover 800 and the window frame groove 202, improves the aesthetics and sealing performance of the entire vehicle, reduces the wind resistance of the vehicle movement, and improves the comfort of the vehicle.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them with similar methods without departing from the scope defined by the spirit of the present invention.
