In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
As shown in connection with fig. 2, an embodiment of the present disclosure provides a sliding door rail including a rail body 1; the guide rail body 1 is provided with a first straight section 11 positioned at the beginning of the guide path; the extension direction of the first straight section 11 coincides with the overall guiding direction of the sliding door rail.
Compared with the automobile sliding door guide rail in the prior art, the sliding door guide rail is provided with the first straight section 11 which is consistent with the overall guiding direction of the sliding door guide rail at the guiding path initial end of the guide rail body 1, so that when the sliding door is in a closing working condition through the roller moving to the guiding path initial end of the sliding door guide rail, an extrapolation experiment and a side door collision experiment are carried out on the sliding door, external thrust or side collision force acting on the sliding door can be vertically transmitted to the first straight section 11 acting on the guide rail body 1 through the hinge and the roller, and the roller can not generate component force in other directions at the first straight section 11, so that the sliding door can keep a covering working condition more stably and firmly. Particularly, when a vehicle suddenly encounters a side collision accident in the running process, the sliding door guide rail provided by the embodiment of the disclosure can effectively improve the safety protection performance of passengers in the vehicle body.
Of course, it should be noted that the sliding door guide rail may be applied to, but not limited to, automobiles, cable cars with sliding doors, subways, vehicles such as high-speed rails, or some building facilities with sliding doors.
In some embodiments, the sliding door rail further comprises a second straight section 13 at the end of the guiding path, and a transition section 12 connected to the first straight section 11, the second straight section 13, respectively; wherein the first straight section 11 and the second straight section 13 are arranged in parallel at intervals.
Specifically, as further detailed in connection with fig. 2, the first straight section 11 and the second straight section 13 are arranged at intervals in parallel along two straight directions and are connected through the transition section 12, so that when the sliding door is opened in a sliding manner, the rollers firstly translate and roll along the first straight section 11, the margin of the backward movement of the sliding door is enabled, the rollers enter the transition section 12 and roll obliquely outwards, the sliding door starts to open while backing and moving outwards, and finally translate and roll along the second straight section 13 again, the sliding door is enabled to finish opening again, and three-stage actions of the backward, outward and backward are enabled to be achieved, and final opening of the sliding door is achieved.
The specific setting mode of the sliding door guide rail has the beneficial effects of simple structure, convenience in opening and stable closing of the sliding door.
In some embodiments, the length of the first straight section 11 is less than the length of the second straight section 13, the transition section 12, respectively.
Specifically, as described in further detail with reference to fig. 2, the length of the first straight section 11 is set to be the smallest relative to the lengths of the second straight section 13 and the transition section 12, so that the roller can only move along the first straight section 11 by a small margin, and the movement margin can be completely compensated by compression of the sliding door and the sealing member or some other connecting members in the door frame, thereby avoiding the problems that motion interference occurs in the opening process of the sliding door and the sliding door cannot be normally opened,
in some embodiments, the length of the first straight section 11 ranges from 40mm to 80mm.
Specifically, in combination with the further detailed description of fig. 2, the length value range of the first straight section 11 is limited to be between 40mm and 80mm, so that on one hand, the problem that the sliding door and the door frame cannot be normally opened due to motion interference caused by overlong rolling distance of the roller along the first straight section 11 due to overlarge length of the first straight section 11 can be avoided, and on the other hand, the roller cannot be effectively supplied to the roller for translational rolling due to overlarge length of the first straight section 11 can be avoided.
Thus, the length of the first straight section 11 is limited to a range of values between 40mm and 80mm, and may be, in particular but not limited to, 40mm, 50mm, 60mm, 80mm, etc.
In some embodiments, the two ends of the transition section 12 are smoothly connected to the first and second straight sections 11 and 13, respectively.
Specifically, as described in further detail with reference to fig. 2, the two ends of the transition section 12 are respectively and smoothly connected with the first straight section 11 and the second straight section 13, so that the roller does not jolt when entering the transition section 12 from the first straight section 11 or entering the second straight section 13 from the transition section 12, and the opening and closing processes of the vehicle door can be smoother.
Of course, the first straight section 11, the transition section 12 and the second straight section 13 may be formed by one-step processing through an integral stamping process, an integral casting process, or the like.
In some specific embodiments, the transition section 12 includes a first circular arc sub-section 121 and a second circular arc sub-section 122; one end of the first arc sub-segment 121 is in tangent butt joint with the first straight segment 11, and the other end of the first arc sub-segment is in tangent butt joint with the second straight segment 122; the other end of the second circular arc sub-section 122 is in tangential abutment with the second straight section 13.
Specifically, as described in further detail with reference to fig. 2, the transition section 12 is specifically configured such that the first arc sub-section 121 and the second arc sub-section 122 are connected to form a rail section similar to an S shape, and the arc lengths and sizes of the first arc sub-section 121 and the second arc sub-section 122 may be specifically configured to be completely equal, and may be distributed in a central symmetry manner with respect to the center of the transition section 12, and since one end of the first arc sub-section 121 is in tangent smooth butt joint with the first straight section 11 and one end of the second arc sub-section 122 is in tangent smooth butt joint with the second straight section 13, the roller can be in a very smooth switching motion state between the first straight section 11 and the first arc sub-section 121 and between the second arc sub-section 122 and the second straight section 13.
The specific arrangement of the transition section 12 has a simple structure, and can enable the roller to smoothly switch back and forth between linear motion and curved motion.
In addition, the application also provides a sliding door guide rail assembly, which comprises a vehicle door, a vehicle body and the sliding door guide rail; the sliding door guide rail is arranged on the vehicle body, and rollers are arranged in the sliding door guide rail; the roller is connected with the vehicle door through a hinge.

In addition, the sliding door guide rail assembly can be particularly but not exclusively applied to automobiles, and can also be applied to traffic car body equipment such as cable cars, high-speed rails and the like.
In some specific embodiments, the vehicle body is provided with three guide rails in the height direction at intervals in sequence; wherein the uppermost guide rail and/or the lowermost guide rail is/are provided as a sliding door guide rail.
Specifically, the uppermost guide rail and the lowermost guide rail in the vehicle body can be set to be the sliding door guide rails, so that the rollers can be limited simultaneously through the first straight sections 11 in the upper sliding door guide rail and the lower sliding door guide rail, and external thrust or side collision force generated during a vehicle door extrapolation experiment or a side collision experiment can be better vertically transferred to act on the first straight sections 11 of the guide rail body 1.
In some embodiments, the centrally located guide rail in the body is arranged with the head end progressively sloping away from the body rail section.
The guide rail at the middle position in the car body is of a structure similar to the sliding door guide rail in the prior art, the head end of the guide rail is gradually far away from the inclined rail section of the car body, so that when the car door is initially opened, the guide rail head end rail section at the middle position can generate a certain outward motion component for the action of the car door, a certain guide is generated for the subsequent motion track of the car door, the actual motion of the car door is still translational consistent with the extending direction of the first straight section 11, and the sealing parts or some other connecting parts in the car door and the car frame can correspondingly deform under compression to compensate the generated motion interference.
In addition, the application also provides a vehicle which comprises a vehicle body and the sliding door guide rail assembly.
The automobile comprises the sliding door guide rail and the sliding door guide rail, and all the beneficial effects of the sliding door guide rail can be realized, and the sliding door guide rail is not repeated herein.
