Description

Technical Field

[0001] The utility model relates to a sliding door for an automobile, in particular to a sliding door hinge assembly for achieving avoidance in the width direction of the automobile. Background Art

[0002] The opening and closing of the lower hinge in the current mass-produced sliding door hinges depends on the width change of the lower guide rail to realize the door hinge opening outwards, such as Figure 1 Therefore, the design of the guide rail occupies a large part of the vehicle chassis space, resulting in insufficient space for the arrangement of other parts. Summary of the invention

[0003] The utility model aims to overcome the defects of the prior art, and provides a sliding door hinge assembly that can avoid the vehicle in the width direction, so as to solve the problem that the traditional guide rail occupies a large width direction dimension and occupies a large space.

[0004] In order to solve the above technical problems, the utility model is achieved as follows:

[0005] A sliding door hinge assembly for achieving avoidance in the vehicle width direction, comprising an upper guide rail and an upper hinge hinged thereto, the upper hinge making lateral movement in the upper guide rail via a width guide wheel at its upper portion; a lower guide rail and a lower hinge hinged thereto, characterized in that: the lower hinge comprises a vehicle body side hinge seat and a vehicle door side hinge seat, the upper end of the vehicle body side hinge seat is rollingly connected to the lower guide rail, the lower end of the vehicle body side hinge seat is hinged to the vehicle door side hinge seat, the vehicle door side hinge seat is a four-bar mechanism, and the movement of the four-bar mechanism enables the vehicle door to move outward.

[0006] The sliding door hinge assembly for achieving avoidance in the vehicle width direction is characterized in that: a four-bar linkage includes a first link, a second link, a third link and a hinge seat; the lower end of the vehicle body hinge chain seat is connected to one end of the first link, and the other end of the first link is provided with two connecting holes, which are respectively connected to one end of the second link and one end of the third link, and the hinge seat is provided with two connecting holes, which are respectively connected to one end of the second link and the other end of the third link.

[0007] The sliding door hinge assembly for achieving avoidance in the vehicle width direction is characterized in that it also includes a height guide wheel, which is vertically arranged in the upper guide rail and the upper part of which presses against the upper guide rail to move horizontally.

[0008] The beneficial effects of the present utility model are as follows: It can be seen from the above technical scheme that the present application provides a sliding door hinge assembly that can achieve avoidance in the vehicle width direction, and adopts a four-link hinge instead of a conventional hinge-type hinge. The function of moving the door outward is realized through the motion trajectory of the four-link, so that the bent guide rail can be designed as a straight guide rail, which greatly releases the width space occupied by the track.

[0009] The present application designs the bent guide rail to be a straight guide rail, which releases space in the width direction of the chassis, and realizes the space occupied by the lower hinge in the sliding door system in the width direction of the door, thereby increasing the bottom plate space for the arrangement of other parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0011] Figure 1 This is a schematic diagram of the existing structure;

[0012] Figure 2 This is a schematic diagram of the structure of this application;

[0013] Figure 3 A decomposition diagram.

[0015] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.

[0016] like Figure 2-4 As shown: a sliding door hinge assembly for avoiding in the width direction of the vehicle, including an upper guide rail 7 and an upper hinge 8 hinged thereto, the upper hinge moves laterally in the upper guide rail through a width guide wheel 9 at its upper portion; a lower guide rail 1 and a lower hinge hinged thereto, the lower hinge including a body side hinge seat 2 and a door side hinge seat, the upper end of the body side hinge seat is rollingly connected to the lower guide rail, the lower end of the body side hinge seat is hinged to the door side hinge seat, the door side hinge seat is a four-bar mechanism, and the movement of the four-bar mechanism enables the door to move outward.

[0017] Furthermore, the four-bar linkage includes a first link 3, a second link 4, a third link 5 and a hinge seat 6; the lower end of the vehicle body hinge chain seat is connected to one end of the first link, and the other end of the first link is provided with two connecting holes, which are respectively connected to one end of the second link and one end of the third link, and the hinge seat is provided with two connecting holes, which are respectively connected to one end of the second link and the other end of the third link.

[0018] Furthermore, it also includes a height guide wheel 10, which is vertically arranged in the upper guide rail, and the upper part of which presses against the upper guide rail to perform lateral movement.

[0019] The present application optimizes the lower hinge from a hinge-type hinge structure to a four-link structure, and relies on the motion trajectory of the four-link to realize the door opening to the outside, thereby optimizing the design of the lower guide rail, designing the bent guide rail into a straight guide rail, and releasing space in the width direction of the chassis;

[0020] Traditional automobile sliding doors only rely on the four-bar design and lack the degree of freedom in the height direction in the motion trajectory. The traditional upper guide rail only has limiting wheels in the width direction. In order to constrain all degrees of freedom, it is necessary to add limiting wheels in the height direction to the upper guide rail to ensure that the four-bar motion follows the trajectory we set.

[0021] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
