[0041] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0042] In some related technologies, since the rear section of the lower guide rail gasket is located at a relatively deep position in the Y direction of the vehicle body, it is located in the blind spot of the operator's field of vision. During assembly, the problem of inaccurate assembly position is likely to occur, which will cause the subsequent lower hinge of the sliding door to not match the lower guide rail gasket, thereby affecting the sliding smoothness and quietness of the sliding door. Based on this, the embodiment of the present disclosure provides a sliding door lower hinge assembly device, which facilitates the blind installation of the lower guide rail gasket, helps to improve the matching accuracy of the lower hinge of the sliding door and the lower guide rail gasket, and enables the lower hinge of the sliding door to be more conveniently installed on the vehicle body.
[0043] Figure 1 Schematic diagram of the structure of the lower hinge assembly device for a sliding door of a vehicle according to some embodiments of the present disclosure. Figure 1 As shown, the sliding door lower hinge assembly device 100 includes: a mounting plate 101, the mounting plate 101 is used to be installed at the lower part of the body of the vehicle, and the mounting plate 101 has a convex structure 102; one or more locating pins 103, each of the one or more locating pins 103 is fixed to the mounting plate 101; a lower guide rail gasket 104, the lower guide rail gasket 104 has one or more circular holes corresponding to the one or more locating pins 103, wherein each of the one or more locating pins 103 passes through a corresponding circular hole in the one or more circular holes, and wherein the side wall of the lower guide rail gasket abuts against the convex structure 102; and a lower guide rail 105, the lower guide rail 105 has a notch and is used to be installed at the lower part of the body and is located above the mounting plate; and a sliding door lower hinge ( Figure 1 ), the lower hinge of the sliding door includes a roller, wherein the roller can slide along the lower guide rail 105 between the lower guide rail 105 and the lower guide rail gasket 104, and wherein the notch is used to enable the roller to enter the lower guide rail through the notch during the installation of the lower hinge of the sliding door.
[0044] Figure 2 Schematic diagram of the position of the lower hinge of the sliding door on the lower guide rail in the lower hinge assembly of the sliding door in some embodiments of the present disclosure. Figure 2 As shown, when the roller 202 of the lower hinge 201 of the sliding door is located at the leftmost end of the lower guide rail 105, the sliding door is in a fully open state. When the roller 202 of the lower hinge 201 of the sliding door is located at the rightmost end of the lower guide rail 105, the sliding door is in a fully closed state.
[0045] Figure 3 It is a schematic diagram of the structure of the positioning pins of some embodiments of the present disclosure.
[0046] According to some embodiments, each of the one or more positioning pins 103 includes a projection welding end 301, wherein a pin column 302 is arranged on the projection welding end 301, and wherein a plurality of projection welding points 303 are arranged on the surface of the projection welding end 301 on the side facing the pin column 302.
[0047] In one example, the pin 302 further includes a guide area 302-1 and a positioning area 302-2, so that the positioning pin 103 can position the lower guide rail gasket on the mounting plate 101 by passing through the circular hole on the lower guide rail gasket 104. Such a structural arrangement enables the positioning pin to guide and position the lower guide rail gasket 104, and can achieve blind installation of the lower guide rail gasket 104 while ensuring precise assembly position and precise matching with the lower hinge of the sliding door.
[0048] Figure 4 FIG. 1 is a side view of a bump structure in some embodiments of the present disclosure. Figure 4 As shown, the height of the protruding point structure 102 is at least 1 mm higher than the thickness of the lower rail gasket 104. Therefore, during the installation of the lower rail gasket 104, the side wall of the lower rail gasket 104 can be pressed against to cooperate with the positioning pin to achieve the positioning of the lower rail gasket 104.
[0049] According to some embodiments, each of the one or more positioning pins 103 is fixed to the mounting plate 101 by projection welding.
[0050] According to some embodiments, the sliding door lower hinge assembly 100 includes two positioning pins 103 , and the two positioning pins 103 are respectively located at two ends of the mounting plate 101 .
[0051] During the assembly of the lower hinge assembly of the sliding door, the lower guide rail gasket is assembled first.
[0052] Figure 5 Schematic diagram of the assembly of the lower rail gasket of some embodiments of the present disclosure. Figure 5 As shown, the lower rail gasket 104 is first positioned mainly through its own circular hole and the positioning pin 103 on the left side of the mounting plate, and at the same time, the side wall of the lower rail gasket 103 located on the inner side of the vehicle is pressed against the protruding point structure 102 on the mounting plate 101 for auxiliary positioning, thereby achieving the overall positioning of the lower rail gasket 104. Then, the lower rail gasket 104 is pushed along the arrow direction to the positioning pin 103 on the right side of the mounting plate to complete the final positioning of the lower rail gasket 104.
[0053] In one example, the lower rail gasket 104 is adhered to the mounting plate 101 by the 3M adhesive at the lower end thereof, so as to fix the lower rail gasket 104 on the mounting plate 102 and complete the installation of the lower rail gasket 104. After the installation of the lower rail gasket 104 is completed, the lower hinge of the sliding door is assembled.
[0054] Figure 6 Schematic diagram of the lower rail baffle and the mounting bracket of some embodiments of the present disclosure. Figure 6 As shown, the sliding door lower hinge assembly 100 further includes: a mounting bracket 106 fixed to one end of the lower rail 105; and a lower rail blocking piece 107 fixed to the mounting bracket 106 for blocking the notch on the lower rail 105. It is understandable that Figure 6 In the embodiment, the lower rail baffle 107 blocks the notch on the lower rail 105, so Figure 6 The notch is not shown.
[0055] The lower guide rail baffle 107 fills the gap area on the lower guide rail 105, so that the entire lower guide rail 105 assembly forms an integral structure, ensuring that the lower hinge of the sliding door can slide smoothly on the lower guide rail gasket 104 from the sliding door closed state to the sliding door maximum open state.
[0056] According to some embodiments, the thickness of the lower guide rail baffle is 2 mm.
[0057] Figure 7 Schematic diagram of the assembly of the lower hinge of the sliding door according to some embodiments of the present disclosure. After the installation of the lower rail gasket 104 is completed, the assembly of the lower hinge of the sliding door can be carried out.
[0058] like Figure 7 As shown, the roller 202 of the lower hinge 201 of the sliding door passes through the notch 701 on the lower guide rail 105 in the Y direction (i.e. Figure 4 The mounting bracket 106 is inserted into the lower guide rail 105 in the direction perpendicular to the paper surface, and then slides along the lower guide rail 105 along the X direction between the lower guide rail 105 and the lower guide rail gasket 104. Thus, the assembly of the lower hinge 201 of the sliding door is achieved. It can be understood that the mounting bracket 106 is used to insert the lower guide rail baffle to cover the notch 701 on the lower guide rail 105. Figure 7 In order to facilitate the illustration of the position of the notch 701 , the figure shows a state where the lower guide rail blocking piece is not inserted.
[0059] According to some embodiments, the size of the notch ranges from 2.5 mm to 3 mm.
[0060] In one example, the size range of the notch of the lower rail 105 in the Z direction and the Y direction is 2.5 mm to 3 mm. This size matches the size of the roller of the lower hinge of the sliding door so that the roller can enter the lower rail 105 through the notch.
[0061] In one example, the mounting bracket 106 and the lower guide rail 105 are connected to form an assembly by welding; the lower hinge 201 of the sliding door is first pushed into the lower guide rail 105 from the Y direction through the notch of the lower guide rail 105, and then the sliding door is pushed along the X direction to drive the lower hinge 201 of the sliding door to move toward the front of the vehicle so that the lower hinge 201 of the sliding door can slide smoothly along the lower guide rail 105; finally, the lower guide rail baffle 107 is inserted into the mounting bracket 106 and locked by the hexagonal pan head screw to complete the installation.
[0062] According to some embodiments of the present disclosure, a vehicle is further provided, comprising the sliding door lower hinge assembly device 100 according to any of the aforementioned embodiments.
