They are relative concepts and may vary depending on the location and usage of the device. Therefore, these or other directional terms should not be interpreted as restrictive.
[0037] The present application provides a door rail middle guide rail installation device, comprising: an installation portion 1, the installation portion 1 is used to install the middle guide rail 5.
[0038] like Figures 1 to 2 As shown, the mounting portion 1 includes a side outer panel 2, a front mounting plate 3 and a rear mounting plate 4 that are separately arranged. Along the length direction of the vehicle body, the front mounting plate 3 is located in front of the rear mounting plate 4.
[0039] like Figure 8 As shown, the front mounting plate 3 includes a first mounting end 30 and a second mounting end 31 that are relatively arranged along the length direction of the vehicle body, and a transition section 32 that is inclined toward the inner side of the vehicle body and has a controllable molding depth is provided between the first mounting end 30 and the second mounting end 31. The front mounting plate 3 in the embodiment of the present application is made of mild steel for ease of molding. The transition section 32 can be stamped, and the stamping depth is determined solely based on the degree of displacement of the middle sliding door toward the inner side of the vehicle body during the closing process, so that the middle guide rail 5 installed on the transition section 32 always maintains a specific distance from the sliding door. For example, the middle guide rail 5 installed on the transition section 32 always maintains a preset design distance from the sliding door. The inner side of the vehicle body refers to the inner side of the vehicle body in the lateral direction.
[0040] like Figure 5 As shown, the side panel 2 is connected to the first mounting end 30. A sealing groove 34 is provided at the connection between the first mounting end 30 and the side panel 2. The sealing groove 34 is used to fill a sealing member. The sealing member can be a sealant or other sealing filler.
[0041] like Figures 6 and 7As shown, the rear mounting plate 4 is connected to the second mounting end 31, and a reinforcement portion is provided on the rear mounting plate 4. The reinforcement portion in the embodiment of the present application can be a reinforcement rib, a reinforcement plate or a reinforcement groove, which is specifically provided according to the force distribution and force strength of the rear mounting plate 4.
[0042] The door center rail mounting device provided in the embodiment of the present application is configured so that the side outer panel 2, the front mounting plate 3 and the rear mounting plate 4 are separately arranged, so that the front mounting plate 3 can be independently provided with a transition section 32 that is inclined toward the inner side of the vehicle body and has an independently controllable depth, so as to adapt to the offset trajectory required for the sliding door to slide toward the inner and outer sides of the vehicle body during the sliding process. This solves the problem that it is difficult to stamp out a front mounting plate 3 with a larger depth to adapt to the sliding door caused by the current one-piece molding of the center guide rail 5 mounting structure. The sealing groove 34 defined between the first mounting end 30 of the front mounting plate 3 and the side outer panel 2 can effectively seal the connection between the front mounting plate 3 and the side outer panel 2 after being filled with a seal.

[0052] The vehicle door assembly provided in the embodiment of the present application is configured so that the side outer panel 2, the front mounting plate 3 and the rear mounting plate 4 are separately arranged, so that the front mounting plate 3 can be independently provided with a transition section 32 that is inclined toward the inner side of the vehicle body and has an independently controllable depth, so as to adapt to the offset trajectory required for the sliding door to slide toward the inner and outer sides of the vehicle body during the sliding process. This solves the problem that it is difficult to stamp out a front mounting plate 3 with a larger depth to adapt to the sliding door due to the current one-piece molding of the center guide rail 5 mounting structure. The sealing groove 34 defined between the first mounting end 30 of the front mounting plate 3 and the side outer panel 2 can effectively seal the connection between the front mounting plate 3 and the side outer panel 2 after being filled with a seal. The reinforcement portion provided on the rear mounting plate 4 increases the structural strength of the rear mounting plate 4 and improves the support effect on the center guide rail 5, so as to extend the service life of the rear mounting plate 4 and ensure the repeated opening and closing of the sliding door.
