[0041] The present utility model provides a scissor door and side door linkage opening mechanism for new energy vehicles. Through a delicate mechanical structure design, seamless switching between the scissor door driving mode and the side door driving mode of the vehicle door is achieved, providing users with an unprecedented personalized and convenient experience.

[0042] The following will detail the linkage opening mechanism and vehicle of the present application through the following embodiments.

[0043] Embodiment 1:

[0044] As Figures 1-3 shown, in this embodiment, a vehicle includes: a vehicle body 10; a vehicle door 20; and a linkage opening mechanism for opening and closing the vehicle door 20 in a scissor door driving mode or opening and closing it in a side door driving mode.

[0045] As Figures 4-6 shown, among them, the linkage opening mechanism includes: a mounting plate 100, which is arranged on the vehicle body 10 and mainly serves as the mounting carrier of the entire mechanism, and at least one first slot portion 110 is arranged thereon; a rotating arm 200; a vehicle door 20 connecting arm, one end of which is rotatably connected to the rotating arm 200, and the other end is connected to the vehicle door 20. At least one second slot portion 310 is also arranged on the vehicle door 20 connecting arm; and a switching component 400 for enabling the vehicle door 20 to open and close in a side door driving mode along the rotation point between the rotating arm 200 and the vehicle door 20 connecting arm; or enabling the vehicle door 20 to be driven by the rotating arm 200 and open and close in a scissor door driving mode.

[0046] The opening mode of the vehicle door 20 is realized by switching the component 400. Specifically, the switching component 400 includes: a slide rail 410 disposed on the rotating arm 200; a slider 420 slidably disposed on the slide rail 410; a switching arm 430 disposed on the slider 420, on which at least one insertion portion 431 is provided; and a driving portion 440 for driving the switching arm 430 to perform a linear motion on the slide rail 410, so that the insertion portion 431 is connected to the first slot portion 110 to lock the rotating arm 200 on the mounting plate 100; or the insertion portion 431 is connected to the second slot portion 310 to lock the connecting arm of the vehicle door 20 on the rotating arm 200.

[0047] In the original solution of the applicant, the driving of the switching rod is realized by using the transmission mode of a gear and a rack, and the switching rod is disposed in the installation cavity of the rotating arm 200. Not only is the installation inconvenient and more components are required, but after a long time, there will be noise between the gear and the rack, affecting the experience. Therefore, in this application, a slide rail 410 and a slider 420 structure are provided. The switching arm 430 is slidably disposed on the rotating arm 200 through the slide rail 410 and the slider 420, and then by using the plugging method, through the combination of the insertion portion 431 and the first slot portion 110 or the second slot portion 310, the free switching of the opening mode of the vehicle door 20 is realized. Not only are fewer components used, but also when the switching arm 430 moves, it is not easy to generate noise, effectively reducing the noise. And during maintenance, only lubricating oil needs to be applied to the slide rail 410 and the slider 420.

[0048] It should be noted that an opening 210 is provided on the rotating arm 200. When the vehicle door 20 is closed, the second slot portion 310 on the connecting arm of the vehicle door 20 passes through the opening 210. By adopting a method similar to that of a bolt, after the insertion portion 431 is embedded in the second slot portion 310, the connecting arm of the vehicle door 20 is locked on the rotating arm 200 to restrict the rotation of the connecting arm of the vehicle door 20. At the same time, the rotating arm 200 is released from the restriction of the mounting plate 100 and can rotate, realizing the opening and closing of the scissor door driving mode.

[0049] It should be noted that the driving portion 440 is a cylinder, a hydraulic cylinder or an electric push rod. The structure of the driving portion 440 is not limited, as long as it can drive the switching arm 430 to perform a linear motion.

[0050] It should be noted that to ensure the strength of the entire mechanism, components such as the mounting plate 100, the connecting arm of the vehicle door 20, the rotating arm 200, and the switching arm 430 are all made of metal sheet metal parts.

[0051] In this embodiment, it further includes: a first driving component 500 for driving the rotating arm 200 to move, so that the vehicle door 20 is opened or closed in a scissor door driving mode; a second driving component (not shown in the figure) for driving the connecting arm of the vehicle door 20 to move, so that the vehicle door 20 is opened or closed in a side-opening door driving mode.

[0052] Regarding the first driving component 500 and the second driving component, the prior art in the background art has been described in detail. In this application, the first driving component 500 and the second driving component are not optimized or improved, so they will not be described in detail in this application.

[0053] Embodiment Two:

[0054] This embodiment is a further improvement based on Embodiment One.

[0055] As Figure 5 shown, in this embodiment, the insertion part 431 is divided into an upper insertion end 4311 and a lower insertion end 4312;

[0056] Among them, the upper insertion end 4311 corresponds to the first slot part 110, and the lower insertion end 4312 corresponds to the second slot part 310; or the upper insertion end 4311 corresponds to the second slot part 310, and the lower insertion end 4312 corresponds to the first slot part 110.

[0057] The upper insertion end 4311 and the lower insertion end 4312 are respectively located at different positions of the switching arm 430, each undertaking the task of docking with different slot parts. Specifically, the upper insertion end 4311 is designed to closely cooperate with the first slot part 110 on the mounting plate 100. When it is necessary to implement the side-opening door driving mode, the upper insertion end 4311 is accurately inserted into the first slot part 110 under the push of the driving part 440, so as to lock the rotating arm 200 on the mounting plate 100, ensuring that the vehicle door 20 can be smoothly opened or closed along the rotation point between the rotating arm 200 and the connecting arm of the vehicle door 20. The lower insertion end 4312 corresponds to the second slot part 310 on the connecting arm of the vehicle door 20. When switching to the scissor door driving mode, the lower insertion end 4312 will accurately dock with the second slot part 310, firmly locking the connecting arm of the vehicle door 20 on the rotating arm 200. At this time, the vehicle door 20 can be gracefully unfolded or retracted in the form of a scissor door under the drive of the rotating arm 200.

[0058] The independent design of the upper insertion end 4311 and the lower insertion end 4312 enables the switching component 400 to flexibly select to dock with different slot parts according to different door opening requirements, thus easily realizing the switching between the scissor door and the side-opening door modes.

[0059] As Figures 5-6As shown, in this embodiment, optimally, there are two first slot portions 110, which are arranged vertically on the mounting plate 100; there are two second slot portions 310, which are arranged vertically on the door 20 connecting arm; there are two insertion portions 431, which are arranged vertically on the switching arm 430;

[0060] Among them, the two first slot portions 110 and the two second slot portions 310 are arranged vertically offset from each other.

[0061] By setting the first slot portion 110, the second slot portion 310, and the insertion portion 431 to be two each, the connection strength is improved.

[0062] The various embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the embodiments disclosed herein.
