DETAILED DESCRIPTION

[0035] To make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. It should be explained that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0036] The embodiments of the present application provide a vehicle door assembly, as shown in the drawings. Figures 1 to 5 The vehicle door assembly includes a first door body 1 and a second door body 2, the first door body 1 is rotatably mounted on a vehicle body 3, the second door body 2 is slidably mounted on the vehicle body 3, and the second door body 2 is located below the first door body 1 in the height direction; a free end of the first door body 1 is provided with a first guide rail 11 matched with the second door body 2.

[0037] The first door body 1 can be in the form of a gull-wing door and is rotatably mounted on the vehicle body 3, such as at the top of the vehicle body 3; the second door body 2 can be in the form of a sliding door and is slidably mounted on the vehicle body 3 by matching with the first guide rail 11 on the first door body 1.

[0038] After the first door body 1 located at the top of the vehicle body 3 is opened, the opening space on the vehicle is greatly increased, so that the driver and passenger can get in and out of the vehicle without bending over, greatly improving the convenience of getting in and out of the vehicle for the rear passengers. The second door body 2 is opened in a sliding manner, i.e., the second door body 2 moves along the length direction (X direction) of the vehicle; and the first door body 1 located at the top of the vehicle body 3 is also not occupied in the width direction (Y direction) of the vehicle when it is rotated to open, so that the space required for opening the vehicle door is small, and the vehicle door can be smoothly opened in a narrow alley or garage, which is convenient and practical. Moreover, when the vehicle door is closed, the first guide rail 11 matched with the second door body 2 can limit the first door body 1 to a certain extent, avoiding the first door body 1 from being opened by mistake. The guide rail connection structure directly arranged on the first door body 1 and the second door body 2 greatly improves the stability of the vehicle door and the sealing performance of the whole system.

[0039] In a specific application, for the opening mode of the door assembly, when opening the door, the second door body 2 is first slid open, and then the first door body 1 is rotated open; when closing the door, the first door body 1 is first rotated closed, and then the second door body 2 is slid closed. For the opening control of the first door body 1 and the second door body 2, it can be automatically realized through a preset program, or it can be manually realized by the driver or passenger, and the present application does not limit this.

[0040] The first guide rail 11 can be fixed on the first door body 1 by spot welding, riveting or the like, or can be directly formed by integral molding.

[0041] In an exemplary embodiment, as shown in Figure 5 , the second door body 2 is provided with a sliding mechanism, which includes an upper hinge assembly 21 at the upper end of the second door body 2, and the upper hinge assembly 21 is arranged to slide in the first guide rail 11.

[0043] Specifically, the upper hinge assembly 21 can include a roller, which is mounted on the second door body 2 through a hinge structure, and the roller slides in the first guide rail 11.

[0044] In an exemplary embodiment, as shown in Figure 1 , Figure 2 and Figure 5 , the sliding mechanism further includes a lower hinge assembly 22 at the lower end of the second door body 2, and a middle hinge assembly 23 between the upper hinge assembly 21 and the lower hinge assembly 22 in the height direction; the vehicle body 3 is provided with a second guide rail 33 cooperating with the lower hinge assembly 22, and a third guide rail 34 cooperating with the middle hinge assembly 23.

[0045] The second door body 2 can be provided with three sliding structures for sliding cooperation with the guide rails, i.e. the upper hinge assembly 21, the middle hinge assembly 23 and the lower hinge assembly 22. The first guide rail 11 cooperating with the upper hinge assembly 21 is located at the free end of the first door body 1, and the second guide rail 33 cooperating with the lower hinge assembly 22 and the third guide rail 34 cooperating with the middle hinge assembly 23 are both located on the vehicle body 3.

[0046] The first guide rail 11, the second guide rail 33 and the third guide rail 34 can be guide rails with a certain curvature at the end, and the guide rails are inwardly contracted along the width direction (Y direction) of the vehicle body 3, so as to facilitate the sliding of the second door body 2 along the guide rails, and finally the second door is embedded in the opening position on the vehicle body 3 to smoothly close the door.

[0047] The upper hinge assembly 21, the middle hinge assembly 23 and the lower hinge assembly 22 can be installed on the second door body 2 by means of bolt fixation. The second guide rail 33 and the third guide rail 34 can be installed on the vehicle body 3 by means of bolt fixation.

[0048] The vehicle door assembly provided by the embodiment of the present application, while comprising the first door body 1 and the second door body 2, ingeniously solves the problem of loose cooperation between the first door body 1 and the second door body 2 by arranging the first guide rail 11 at the free end of the first door body 1, and improves the sliding accuracy of the second door body 2.

[0049] In an exemplary embodiment, as shown in Figure 5 The upper hinge assembly 21 is arranged at the front end of the second door body 2 along the door closing sliding direction, the middle hinge assembly 23 is arranged at the rear end of the second door body 2 along the door closing sliding direction, and the lower hinge assembly 22 is arranged at the front end of the second door body 2 along the door closing sliding direction.

[0050] The upper hinge assembly 21 and the lower hinge assembly 22 are arranged at the front part along the length direction of the vehicle body 3, so as to realize the rear sliding of the second door body 2 for door opening. The middle hinge assembly 23 is arranged at the rear part along the length direction of the vehicle body 3, so as to cooperate with the third guide rail 34 located at the rear of the door opening of the vehicle body 3, and effectively hide the middle hinge assembly 23, so that the middle hinge assembly 23 cannot be seen by the person inside the vehicle when the door is completely closed, and the appearance of the vehicle is improved.

[0051] It should be understood that the specific positions of the upper hinge assembly 21, the middle hinge assembly 23 and the lower hinge assembly 22 can be adjusted according to actual conditions, and are not limited to the above arrangement positions, and the present application does not limit this.

[0052] In an exemplary embodiment, as shown in Figure 4 The first door body 1 is installed on the top of the vehicle body 3 through the rotating mechanism 14; the rotating mechanism 14 comprises a rotating hinge 141 and an extension support rod 142, the hinge end of the first door body 1 is connected with the vehicle body 3 through the rotating hinge 141; one end of the extension support rod 142 is connected with the first door body 1, and the other end is connected with the vehicle body 3, and the extension support rod 142 drives the first door body 1 to rotate around the rotating hinge 141.

[0053] The rotating hinge 141 realizes the rotation of the first door body 1 relative to the vehicle body 3, and the extension support rod 142 is elongated or shortened to drive the first door body 1 to rotate, in other words, the opening or closing of the first door body 1 is realized by controlling the extension and contraction of the extension support rod 142. The two ends of the extension support rod 142 can be connected with the vehicle body 3 and the first door body 1 respectively by means of bolt connection.

[0054] The extension support rod 142 can be connected with a driving device, and automatic control of the extension support rod 142, i.e. automatic opening and closing of the first door body 1, is realized by a motor or other mechanism.

[0055] In an example embodiment, as shown in Figure 4 The first door body 1 includes a door body sheet metal 12 and a light-transmitting member 13 arranged on the door body sheet metal 12. The number of the telescopic struts 142 is two, and each is arranged on the two sides of the light-transmitting member 13. The part of the door body sheet metal 12 on the two sides of the light-transmitting member 13 blocks the telescopic struts 142.

[0056] The light-transmitting member 13 can be glass or other components, which improves the wide view in the vehicle. The light-transmitting member 13 can be arranged at the middle position of the door body sheet metal 12. The telescopic struts 142 are arranged on the two sides of the light-transmitting member 13 to avoid blocking the light-transmitting member 13 and affecting the view. Meanwhile, the door body sheet metal 12 on the two sides of the light-transmitting member 13 can block the telescopic struts 142 to avoid directly seeing the telescopic struts 142 from the outside of the vehicle, which improves the appearance of the vehicle.

[0057] It should be understood that the light-transmitting member 13 can also not be arranged on the first door body 1. In other words, the first door body 1 can be a complete sheet metal without glass. In this case, the arrangement position of the telescopic struts 142 does not need to consider blocking and avoiding, and can be adjusted according to the requirement. The present application does not limit this.

[0058] The vehicle door assembly provided by the embodiment of the present application not only serves as an appearance part and a moving part of the whole vehicle to ensure the appearance, safety and sealing, and provide basic functions such as passenger access, but also has the function of attracting attention and creating a sense of ceremony, which enriches the functions of the vehicle door assembly.
