[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] It should be explained first that the middle slide rail mounting plate assembly proposed in the present application is a part of the automobile sliding door system. Its function is to provide an installation fixing point for the middle slide rail and to provide the required rigidity and strength for the mounting point, thereby ensuring that the sliding stroke of the sliding door meets the use requirements while also ensuring the stability of the sliding door during the sliding process.

[0041] Please also read Figures 1 to 6 The middle slide rail mounting plate assembly provided by the present application is now described. The middle slide rail mounting plate assembly provided by the present application comprises a middle slide rail mounting plate body 1 and a middle slide rail mounting cover plate 2.

[0042] The middle slide rail mounting plate body 1 is arranged below the rear side window glass and extends along the X direction of the vehicle body; based on the conventional vehicle structure (mainly the positions of the side inner panel 100 and the side outer panel 200), the front end of the middle slide rail mounting plate body 1 is connected to the side inner panel 100 and the side outer panel 200, and the rear end of the middle slide rail mounting plate body 1 is located on the inner side of the side outer panel 200 and connected to the side outer panel 200.

[0043] In this embodiment, the middle slide rail mounting plate body 1 is made of steel plate and formed by a stamping process, mainly to ensure the installation length of the middle slide rail on the side panel assembly along the X-direction of the vehicle body, so as to achieve the travel requirement of the rear door opening in the X-direction of the vehicle body, and to ensure that the installation strength and rigidity of the middle slide rail meet the requirements.

[0044] The middle slide rail mounting cover plate 2 is connected to the rear end of the middle slide rail mounting plate body 1, and is located on the rear side of the middle slide rail, between the middle slide rail mounting plate body 1 and the side outer plate 200; thus, a cavity open to the middle slide rail is formed between the inner side surface of the middle slide rail mounting cover plate 2 and the outer side surface of the middle slide rail mounting plate body 1, and this cavity is used to accommodate the pulley seat, and the traction member related to the pulley seat extends to the middle slide rail through the opening of the cavity.

[0045] In the embodiment of the present application, the installation position of the middle slide rail is determined by the middle slide rail mounting plate body 1; on this basis, the cavity structure between the middle slide rail mounting cover plate 2 and the middle slide rail mounting plate body 1 is used for reinforcement to balance the structural strength of the front and rear ends of the middle slide rail mounting plate body 1; at the same time, the cavity structure can also accommodate the pulley seat to center the drive of the sliding door.

[0046] Compared with the prior art, the middle slide rail mounting plate assembly provided in this embodiment can provide an installation space for the pulley seat while ensuring that the shape of the entire vehicle is not damaged, so that the pulley seat can be fixed to the end of the middle slide rail and a central drive can be realized, thereby ensuring the stability of the sliding door during movement, reducing fatigue damage to related structures during the movement of the sliding door, and extending the service life of the vehicle sliding door system.

[0047] In some embodiments, Figure 2 As shown, the outer side surface of the middle slide rail mounting plate body 1 has a concave structure 11 ; during actual assembly, the middle slide rail is arranged in the concave structure 11 , and the middle slide rail mounting cover plate 2 is arranged on the outer side of the concave structure 11 .

[0048] By adopting the above technical solution, even if the middle slide rail mounting cover plate 2 is a plane, due to the presence of the concave structure 11, a cavity structure for the pulley seat to be placed can still be formed between the middle slide rail mounting plate body 1 and the middle slide rail mounting cover plate 2.

[0049] When the middle slide rail installation cover plate 2 is not in contact with the concave surface of the inner concave structure 11, the cavity formed by the inner concave structure 11 and the middle slide rail installation cover plate 2 is through along the X direction of the vehicle body; however, in this case, some impurities will enter the position of the pulley seat, thereby affecting the normal use of the pulley seat, causing noise or unsmooth movement. In order to solve this technical problem, in some embodiments, such as Figure 3As shown, the rear end of the middle slide rail mounting cover plate 2 is connected to the recessed surface of the inner recessed structure 11; that is, the rear end of the middle slide rail mounting cover plate 2 seals the rear end opening of the cavity, so that the cavity formed by the inner recessed structure 11 and the middle slide rail mounting cover plate 2 only has an opening toward the middle slide rail, ensuring long-term normal use of the pulley seat.

[0050] In some embodiments, Figure 3 As shown, the middle slide rail installation cover plate 2 adopts a structure that bulges toward the side outer plate 200 to cooperate with the aforementioned concave structure 11, increase the volume of the enclosed space, and ensure the normal use of the pulley seat.

[0051] In some embodiments, Figure 5 As shown, the middle slide rail mounting cover plate 2 is also connected to the inner side surface of the side outer panel 200 to form a three-layer panel structure of the rear end of the middle slide rail mounting plate body 1, the middle slide rail mounting cover plate 2 and the side outer panel 200, corresponding to the three-layer panel structure of the side inner panel 100, the front end of the middle slide rail mounting plate body 1 and the side outer panel 200, thereby achieving the technical purpose of unifying (or approaching the same) the strength of the front and rear ends of the middle slide rail mounting plate body 1.

[0052] In some embodiments, Figure 4 As shown, the middle slide rail mounting plate body 1 is provided with an avoidance hole 12 which penetrates along the Y direction of the vehicle body and allows part of the pulley seat to pass through; due to the existence of this avoidance hole 12, the space inside the middle slide rail mounting plate body 1 can be utilized to ensure the normal use of the pulley seat.

[0053] In some embodiments, Figure 6 As shown, the middle slide rail mounting plate body 1 has several groups of connection structures 3 connected to the middle slide rail. Through the connection function of the connection structures 3, the installation position of the middle slide rail can be limited and the middle slide rail can be fixedly connected to the middle slide rail mounting plate body 1.

[0054] In some embodiments, Figure 6 As shown, each set of connection structures 3 includes a through hole 31 and a fastener 32 .

[0055] The through hole 31 is provided on the middle slide rail mounting plate body 1. Specifically, the middle slide rail mounting plate body 1 has a straight portion and an inclined portion; the straight portion has at least two groups of connection structures 3, and the inclined portion has at least one group of connection structures 3; accordingly, the straight portion has at least two through holes 31, and the two through holes 31 are parallel to each other; the axial direction of the through hole 31 provided on the inclined portion forms an angle with the axial direction of the through hole 31 on the straight portion.

[0056] The fastener 32 is arranged in the through hole 31 and connects the middle slide rail mounting plate body 1 and the middle slide rail; specifically, when the middle slide rail is placed on the middle slide rail mounting plate body 1 and overlaps with the through hole 31, the fastener 32 can connect the middle slide rail mounting plate body 1 and the middle slide rail to prevent either of them from moving relative to the through hole 31, thereby realizing the positioning connection between the middle slide rail mounting plate body 1 and the middle slide rail.

[0057] In some embodiments, Figure 6 As shown, the fastener 32 includes a positioning nut 321 and a positioning bolt 322 .

[0058] The positioning nut 321 is fixedly connected to the middle slide rail mounting plate body 1 and communicates with the aforementioned through hole 31 .

[0059] Among them, in order to avoid occupying the space between the middle slide rail mounting plate body 1 and the middle slide rail, the positioning nut 321 can be fixed on the inner side of the middle slide rail mounting plate body 1; on the other hand, in order to improve the convenience of repair and maintenance of the positioning nut 321 on the vehicle, the positioning nut 321 can also be fixed on the outer side of the middle slide rail mounting plate body 1, and a corresponding sinking structure is set on the inner side of the middle slide rail or the outer side of the middle slide rail mounting plate body 1.

[0060] The positioning bolt 322 is threadedly connected to the positioning nut 321, and its head is located on the outside of the middle slide rail and abuts against the middle slide rail, thereby limiting the outward movement of the middle slide rail relative to the middle slide rail mounting plate body 1, thereby realizing a fastened connection between the middle slide rail mounting plate body 1 and the middle slide rail based on the positioning of the through hole 31.

[0061] In other embodiments, the fastener 32 can be made of glue dots with high viscosity, or pre-assembled parts that can be melted when heated; after this component is assembled in the through hole 31, the outside world applies high temperature or high pressure to the connection, which can also achieve a fastened connection between the middle slide rail mounting plate body 1 and the middle slide rail based on the positioning of the through hole 31.

[0062] In some embodiments, Figure 4 and Figure 6 As shown, the positioning nut 321 is located on the inner side of the middle slide rail mounting plate body 1, and the positioning nut 321 has a docking plate 3211 extending radially outward and connected to the inner side surface of the mounting plate body; during actual assembly, the positioning nut 321 can be fixedly connected by welding the docking plate 3211 to the middle slide rail mounting plate body 1.

[0063] That is to say, the positioning nut 321 and the docking plate 3211 together form a nut plate, and the nut plate is connected to the middle slide rail mounting plate body 1 by spot welding, which plays the role of providing a screw connection point for the middle slide rail.

[0064] Based on the same inventive concept, an embodiment of the present application also provides a car, comprising the middle slide rail mounting plate assembly proposed in any of the aforementioned items.

[0065] The beneficial effects of the automobile provided by this embodiment are the same as the beneficial effects of the aforementioned middle slide rail mounting plate assembly, and will not be repeated here.

[0066] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
