[0031] Please combine Figures 1 to 4 As shown, the present application first provides a vehicle door connection structure, including a vehicle body 100, a front door 200a, a rear door 200b and a connection assembly 300, wherein the vehicle body 100 is provided with a door frame 110;
[0032] The connecting assembly 300 includes a guide rail 10, a slider 20, a driving member 30, and a transmission gear 40. The guide rail 10 is fixed in the door frame 110. The guide rail 10 has a slide groove 11 along the length of the vehicle body 100. The slider 20 is slidably connected to the inner wall of the slide groove 11. The driving member 30 is fixed to the guide rail 10 and slidably connected to the transmission gear 40. The driving member 30 can drive the transmission gear 40 to move along its own axis and rotate around its own axis.
[0033] The front door 200 a and the rear door 200 b are both provided with a connecting rod 210 and a rack 220 . The rack 220 is engaged with the transmission gear 40 . The connecting rod 210 is slidably connected to the slider 20 along the width direction of the vehicle body 100 .
[0034] In this application, the front door 200a and the rear door 200b are connected to the vehicle body 100 through the connecting assembly 300, so that the front door 200a and the rear door 200b can slide open to obtain a larger door opening to meet the different needs of users.
[0035] Specifically, the driving member 30 can drive the transmission gear 40 to move along its own axis (i.e., the width direction of the vehicle body 100) to push the front door 200a and the rear door 200b to protrude outward from the door frame 200, so as to ensure that the doors are flush with the outer surface of the vehicle body 100 when closed, thereby reducing wind resistance and improving the overall aesthetics.
[0036] More specifically, the transmission gear 40 is in contact with the front door 200a and the rear door 200b along its own axis (not shown) to ensure that the extension and retraction of the transmission gear 40 can drive the front door 200a and the rear door 200b to complete the extension and retraction along the width direction of the vehicle body 100.
[0037] The driving member 30 can also drive the transmission gear 40 to rotate, thereby driving the front door 200a and the rear door 200b to slide along the length direction of the vehicle body 100 through the rack 220 to complete the opening and closing of the doors.
[0038] It is worth mentioning that the front door 200a and the rear door 200b of the present application are both connected to the guide rail 10 through a connecting assembly 300, so the two can share the guide rail to achieve some special opening methods. For example, the rear door 200b is opened backward, and the front door 200a is moved backward to the rear door opening position, so that the front half of the door frame 110 is opened forward to facilitate the front driver or passenger to enter the front seat.
[0039] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, two groups of connecting components 300 are fixed in the door frame 110 along the length direction of the vehicle body 100, wherein one group of connecting components 300 close to the front of the vehicle is correspondingly connected to the front door 200a, and the other group of connecting components 300 is correspondingly connected to the rear door 200b.
[0040] Of course, in some other embodiments, the front door 200a and the rear door 200b may also share a guide rail 10 to obtain a larger sliding length.
[0041] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, each group of connecting components 300 includes two guide rails 10, which are respectively fixed on the upper and lower sides of the door frame 110. A slider 20, a driving member 30 and a transmission gear 40 are provided in each guide rail 10 to improve the connection stability between the door and the connecting component 300, and also to increase the sliding stability of the door during the sliding process.
[0042] Please combine Figure 1 、 Figure 2 as well as Figure 3As shown, in some embodiments, the slider 20 is located closer to the center of the two groups of connecting components 300 than the driving member 30; by arranging the slider 20 on the driving member 30 closer to the center of the two groups of connecting components 300, interference between the slider 20 and the driving member 30 can be avoided, thereby increasing the maximum opening degree that the door can open by moving away from the center of the door frame 110.
[0043] Preferably, the driving member 30 is fixed to an edge of the guide rail 10 along the length direction of the vehicle body 100 .
[0044] It is not difficult to understand that when the position of the rack 220 on the vehicle door is constant, the further the driving member 30 is away from the center position of the door frame 110, the greater the maximum opening that the door can open by moving away from the center of the door frame 110. Therefore, fixing the driving member 30 to the edge of the guide rail 10 along the length direction of the vehicle body 100 can enable the door to obtain the maximum opening when it is opened away from the center of the door frame 110.
[0045] Please refer to Figure 5 As shown, in some embodiments, a step groove 11a is provided on the bottom wall of the slide groove 11, and the driving member 30 is fixed in the step groove 11a, and at least part of the projection of the driving member 30 along the length direction of the vehicle body 100 coincides with the slider 20. On the one hand, the step groove 11a can play a positioning effect when the driving member 30 is installed. On the other hand, the slider 20 can be blocked by the driving member 30 when sliding along the slide groove 11, thereby playing a limiting effect on the slider 20 through the driving member 30.
[0046] In some embodiments, the driving member 30 can be composed of multiple power members, thereby driving the transmission gear 40 to complete two different movements respectively, or it can be completed by only one power member and the corresponding transmission assembly to drive the transmission gear 40 to complete two different movements in sequence according to the required movement order. This application does not make further limitations here.
[0047] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the slider 20 includes a large diameter portion 21 and a small diameter portion 22 fixed to each other, the small diameter portion 22 is close to the opening of the slide groove 11, and the cross section of the slide groove 11 is contoured corresponding to the large diameter portion 21 and the small diameter portion 22.
[0048] With this arrangement, the large diameter portion 21 is clamped in the slide groove 11 along the width direction of the vehicle body 100 to play a certain limiting role, thereby preventing the slider 20 from escaping from the slide groove 11 along the width direction of the vehicle body 100.
[0049] Please combine Figure 4 as well as Figure 5As shown, in some embodiments, the large diameter portion 21 is spherical to reduce the sliding resistance between the slider 20 and the slide groove 11, and to minimize the difficulty of the door sliding relative to the body 100 while ensuring the limiting effect.
[0050] In some embodiments, the small-diameter portion 22 is provided with a connecting groove, and the connecting rod 210 is inserted into the connecting groove. The two are slidably connected with a certain damping force.
[0051] Please refer to Figure 3 As shown, in some embodiments, the front door 200a and the rear door 200b are both provided with a rack groove 230, and the upper and lower inner walls of the rack groove 230 are fixed with racks 220. The upper and lower rows of racks 220 are engaged with the transmission gear 40 to improve the driving stability of the transmission gear 40 to drive the door to move.
[0052] A second aspect of the present application provides an MPV vehicle, comprising the above-mentioned door connection structure.
[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
