[0039] The guide groove structure of an automobile is the main connecting component between the door glass and the door. The guide groove structure is generally installed on the sheet metal main body to guide the lifting trajectory of the glass and seal the gap between the door glass and the sheet metal main body. At present, most commercial vehicles on the market use sliding doors, and the guide groove structure of the sliding door is usually installed in an embedded structure inside the installation groove of the sheet metal main body. However, due to the influence of the installation space of the glass and the welding process on the installation groove structure of the sliding door sheet metal, there will be a situation where the outer side wall of the installation groove is missing at the C-pillar end. Therefore, it is impossible to provide sufficient limiting and positioning effects on the outer side of the guide groove structure in this area, resulting in a non-fitting situation between the glass and the guide groove structure at the missing outer side wall of the installation groove, affecting its sealing performance and appearance.

[0040] The present invention provides a door structure 100. It should be noted that, without special explanation, the front-back direction in the following description refers to the length direction of the automobile, the inner-outer side refers to the width direction of the automobile, where the inner side refers to the inner side of the automobile and the outer side refers to the side of the automobile communicating with the outside, and the up-down direction refers to the height direction of the automobile.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 4 In an embodiment of the present invention, the door structure 100 includes a sheet metal main body 1, a guide groove structure 2, a glass 3, a decorative member 4, and a limiting member 5. Among them, the sheet metal main body 1 is formed with a window 11 communicating its inner and outer sides. An installation groove 12 is formed on the inner side wall of the window 11. The installation groove 12 extends along the circumference of the window 11. The installation groove 12 has an inner side wall 121 and an outer side wall 122. Among them, at least a part of the outer side wall 122 is missing; the guide groove structure 2 is installed in the installation groove 12 and defines a guide groove; the glass 3 is installed in the window 11, and the periphery of the glass 3 cooperates with the guide groove; the decorative member 4 is arranged on the outer side of the sheet metal main body 1; the limiting member 5 is arranged on the inner side of the decorative member 4 and corresponds to the outer side wall 122 of the installation groove 12.

[0042] The technical solution of the present invention is to provide a limiting member 5 on the decorative member 4. At the same time, the decorative member 4 is installed on the outer side of the sheet metal main body 1. In the missing part of the outer side wall 122 of the installation groove 12, the outer side of the guide groove structure 2 is limited by the limiting member 5, and the inner side of the guide groove structure 2 is limited by the inner side wall 121 of the installation groove 12; in the part where the outer side wall 122 of the installation groove 12 is complete, the outer side of the guide groove structure 2 is limited by the outer side wall 122 of the installation groove 12, and the inner side of the guide groove structure 2 is limited by the inner side wall 121 of the installation groove 12. Thus, the guide groove structure 2 is limited in each area of the installation groove 12, ensuring the fit between the glass 3 and the guide groove structure 2, and solving the problem that the guide groove structure 2 and the glass 3 cannot fit due to the lack of an outer limiting structure at the missing part of the outer side wall 122 of the installation groove 12.

[0043] It should be noted that the present invention is not limited to the case where the outer side wall 122 of the installation groove 12 at the C-pillar end of the sliding door of a commercial vehicle is missing. As long as the side wall of the installation groove 12 in the window 11 part of the sheet metal main body 1 is missing, it can be applied. Specifically, the missing part of the outer side wall 122 is not limited to the C-pillar part, and can also be the top of the window 11, or the front and rear sides. The present invention does not limit this.

[0044] In order to provide a receiving space for the movement of the glass 3 of the window 11, in an embodiment of the present invention, the sheet metal main body 1 further includes a receiving cavity, and the receiving cavity includes an opening that communicates with the window 11 on one side. With such a setting, when a passenger needs to open the window 11, the glass 3 can be moved into the receiving cavity to open the window 11. It should be noted that the present invention does not limit the position of the receiving cavity. The receiving cavity can be arranged on the front and rear sides or the upper and lower sides of the window 11. In an embodiment of the present invention, preferably, the receiving cavity is arranged on the lower side of the window 11.

[0045] Please refer to Figure 3 and Figure 4 , in an embodiment of the present invention, a part of the outer side wall 122 is missing to form a partially missing area corresponding to a part of the inner side wall 121. The limiting member 5 is arranged inside the decorative member 4 and corresponds to the outside of the partially missing area. The installation groove 12 of the partially missing area is hook-shaped. A part of the guide groove structure 2 on the inner side wall 121 is supported by the inner side wall 121 of the installation groove 12, and a part of the guide groove structure 2 where the outer side wall 122 is partially missing lacks support. For this reason, the limiting member 5 is arranged inside the decorative member 4 and corresponds to the outside of the partially missing area. The limiting member 5 can replace the part where the outer side wall 122 of the installation groove 12 is partially missing to provide support for the guide groove structure 2, so as to ensure that the structures of the installation groove 12, the guide groove structure 2 and the glass 3 in this area are tightly structured and well-fitted.

[0046] Please refer to Figure 3 and Figure 5 , in an embodiment of the present invention, the outer side wall 122 is completely missing to form a completely missing area corresponding to a part of the inner side wall 121. The limiting member 5 is arranged inside the decorative member 4 and corresponds to the outside of the completely missing area. The installation groove 12 of the completely missing area is L-shaped. A part of the guide groove structure 2 on the inner side wall 121 is supported by the inner side wall 121 of the installation groove 12, and a part of the guide groove structure 2 where the outer side wall 122 is completely missing lacks support. For this reason, the limiting member 5 is arranged inside the decorative member 4 and corresponds to the outside of the completely missing area. The limiting member 5 can replace the part where the outer side wall 122 of the installation groove 12 is completely missing to provide support for the guide groove structure 2, so as to ensure that the structures of the installation groove 12, the guide groove structure 2 and the glass 3 in this area are tightly structured and well-fitted.

[0047] In order to fix the guide groove structure 2 to the installation groove 12, in the embodiment of the present invention, the guide groove structure 2 includes an installation part; correspondingly, the installation groove 12 includes a matching part for mating and installing with the installation part. It should be noted that the present invention does not limit the specific forms of the installation part and the matching part, as long as the guide groove structure 2 can be fixed to the installation groove 12. In the embodiment of the present invention, the installation part is a buckle groove structure, and the matching part includes the inner side wall 121 and the outer side wall 122 of the installation groove 12. The installation of the guide groove structure 2 can be completed by directly buckling the installation part into the inner side wall 121 and the outer side wall 122 of the installation groove 12, which is convenient for workers to install.

[0048] In order to adjust the position of the glass 3 according to the needs of the user, in the embodiment of the present invention, the glass 3 is in sliding fit with the guide groove. During its moving stroke, the glass 3 has a first position where at least part of it is placed in the accommodating cavity and a second position where it is completely placed at the window 11. When the user needs to completely close the automobile window 11, the glass 3 can be slid to the second position to completely close the automobile window 11. When the user needs to open the automobile window 11, the glass 3 can be slid to the first position. It should be noted that the first position includes the position where part of the glass 3 is placed in the accommodating cavity and part is placed at the automobile window 11, and the position where the glass 3 is completely placed in the accommodating cavity. With such a setting, it is convenient for the user to choose to completely close the automobile window 11, partially open the automobile window 11, or completely open the automobile window 11 according to their own needs.

[0049] In order to ensure the sealing performance of the guide groove structure 2 and facilitate the sliding of the glass 3, in the embodiment of the present invention, the material of the guide groove structure 2 includes rubber. The guide groove structure 2 made of rubber separates the installation groove 12 and the glass 3. The glass 3 directly contacts the guide groove structure 2 made of a relatively soft rubber material, avoiding the direct contact between the glass 3 and the rigid installation groove 12, which can well protect the glass 3. At the same time, rubber itself has good waterproofness and sealing performance, which can effectively prevent water seepage at the automobile window 11 and ensure the sound insulation effect.

[0050] In an embodiment of the present invention, the dimensions of the limiting member 5 include a length of 78 mm - 82 mm, a width of 4 mm - 6 mm, and a thickness of 0.8 mm - 1.2 mm. Since the size of the missing part of the outer side wall 122 of the mounting groove 12 is limited, in order to save materials, the dimensions of the limiting member 5 are set to a length of 78 mm - 82 mm, a width of 4 mm - 6 mm, and a thickness of 0.8 mm - 1.2 mm. It should be noted that the present invention does not specifically limit the installation position of the limiting member 5. The specific installation position needs to be adjusted according to the doors of different models and the missing parts of the outer side wall 122 of the mounting groove 12 at different positions, as long as it is ensured that the position of the limiting member 5 on the decorative member 4 can correspond to the missing part of the outer side wall 122 of the mounting groove 12 after adjustment.

[0051] In an embodiment of the present invention, in order to determine whether the installation position of the limiting member 5 is appropriate, after the decorative panel provided with the limiting member 5 is assembled on the outer side of the sheet metal main body 1, if there is no gap between the guide groove structure 2 and the glass 3 observed, and the glass 3 can slide normally and continuously without other abnormal phenomena such as noise, it indicates that the installation position of the limiting member 5 is appropriate and can provide an outer limit for the guide groove structure 2. If there is an obvious gap between the guide groove structure 2 and the glass 3 observed, and the sliding of the glass 3 is not continuous or abnormal phenomena such as noise occur, it indicates that the size or installation position of the limiting member 5 is not appropriate and needs to be readjusted.

[0052] In an embodiment of the present invention, the material of the limiting member 5 includes foam. Selecting foam as the material, on the one hand, the foam itself is a flexible material and has elasticity, and will not cause too much damage to the guide groove structure 2 when providing a limit. On the other hand, in an embodiment of the present invention, a sticky material is provided on one side of the foam, and the foam is installed on the decorative panel through the sticky material, which is convenient and fast. In a specific embodiment of the present invention, the sticky material is preferably an adhesive.
