[0040] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0042] See also Figure 1 and Figure 2 The present embodiment provides an adjustable tail guide structure, which is used to be installed at the tail of the vehicle body 600. The adjustable tail guide structure includes a foldable guide member. When the foldable guide member is opened, it protrudes toward the rear of the vehicle body 600 and is streamlined, and is used to guide the gas behind the vehicle body 600; the foldable guide member can be retracted to the tail of the vehicle body 600 after being folded.

[0043] When there is a problem of large wind resistance, the foldable guide is opened, and the streamlined foldable guide is used to guide the gas behind the vehicle body 600, which can effectively reduce wind resistance, not only improving driving safety, providing feasible conditions for increasing vehicle speed, meeting the driver's demand for high-speed driving, but also saving vehicle energy consumption and energy. When there are requirements for vehicle size or the wind resistance is small, the foldable guide is folded and retracted to the rear of the vehicle body 600, so that the vehicle basically restores the original volume of the vehicle body 600, which can reduce the size of the vehicle, facilitate merging, and occupy a smaller area when parking, and can be parked in a smaller parking space.

[0044] The adjustable tail guide structure provided in this embodiment is particularly suitable for small and micro vehicles with relatively large wind resistance. It can enable small and micro vehicles to approach or even exceed the speed that ordinary vehicles can achieve, which is conducive to alleviating the contradiction between low wind resistance and lightweight and low cost of the vehicle, and achieving low driving resistance while ensuring passenger space.

[0045] Preferably, the foldable guide member may include an airbag 100, which can be opened after being inflated. The shape of the airbag 100 only needs to be pre-designed, and the airbag 100 can be expanded and fully formed into a streamlined structure under the action of air pressure; the airbag 100 can be folded toward the rear of the vehicle body 600 after being deflated. The airbag 100 is mainly expanded by gas. On the one hand, the volume occupied by the airbag 100 after being folded is small, which is conducive to reducing the impact of the adjustable rear guide structure on the overall size of the vehicle, and can even be completely retracted into the receiving groove at the rear of the vehicle body 600; on the other hand, the airbag 100 is light in weight, which is conducive to reducing the overall weight of the adjustable rear guide structure, and then reducing the impact of the additional adjustable rear guide structure on the vehicle load, so as to save vehicle energy. Specifically, the airbag 100 can be made of a lightweight film material.

[0046] Furthermore, the foldable deflector may also include a support frame 200, which is rotatably connected to the rear of the vehicle body 600, and the support frame 200 is connected to the airbag 100. During the opening of the airbag 100, the support frame 200 may be driven by the airbag 100 to rotate in a direction away from the vehicle body 600. After the airbag 100 is opened, the support frame 200 may support the airbag 100. With the support of the support frame 200, the airbag 100 is not prone to tilt or shake, thereby improving the stability of the adjustable rear deflector structure. During the folding of the airbag 100, the support frame 200 may be driven by the airbag 100 to rotate in a direction close to the vehicle body 600 until it rotates to the rear of the vehicle body 600.

[0047] See also Figure 3 and Figure 5In the specific structure of the support frame 200, a support cross bar 210 and two support side bars 220 can be set, and one end of each support side bar 220 is rotatably connected to the lower side of the rear of the vehicle body 600, and the two support side bars 220 are respectively close to the two side surfaces of the airbag 100; the other ends of the two support side bars 220 are respectively connected to the two ends of the support cross bar 210, and the support cross bar 210 is close to the top surface of the airbag 100, and the two ends of the support cross bar 210 are respectively connected to the two sides of the airbag 100, so that the support effect of the support frame 200 on the airbag 100 can be guaranteed. Among them, the support side bars 220 can be set as telescopic bars to adapt to the volume change of the airbag 100. Specifically, the support cross bar 210 is set horizontally, and the rotation axis of the support side bars 220 can be set as a horizontal rotation axis.

[0048] See also Figure 4 , cords may be fixed on the airbag 100, and the cords include warp cords 300 and weft cords 400, wherein the warp cords 300 are arranged to extend along the front-rear direction of the airbag 100, and the weft cords 400 are annular and arranged along the axial direction of the airbag 100, and the warp cords 300 and the weft cords 400 are staggered to ensure the streamlined shape of the airbag 100, and further ensure the diversion effect of the airbag 100. Among them, there are a plurality of warp cords 300, which are densely distributed in the airbag 100, and the lengths of the plurality of warp cords 300 are not the same; there are also a plurality of weft cords 400, which are densely distributed in the airbag 100, and the lengths of the plurality of weft cords 400 are not the same.

[0049] The above-mentioned cords include elastic cords and rigid cords, wherein the elastic cords can be stretched and retracted as the size of the airbag 100 changes, so that the elastic cords can adapt to the size changes of the airbag 100. When the size of the airbag 100 changes within a certain range, the elastic cords can form a certain tension on the airbag 100, so that the airbag 100 can maintain a streamlined shape at different sizes; when the airbag 100 is stretched to the limit size, the rigid cords can be tightened, at this time, the shape of the airbag 100 can be better restricted to ensure its streamlined shape, and the elastic cords can be prevented from being broken due to infinite elongation, so as to ensure the reliability of the airbag 100 at the maximum size. Among them, the elastic cords can be elastic rubber bands, and the rigid cords can be fishing net lines. The elastic cords can include any one or both of the above-mentioned warp cords 300 and the above-mentioned weft cords 400, and the rigid cords can also include any one or both of the above-mentioned warp cords 300 and the above-mentioned weft cords 400.

[0050] See also Figure 5A fixing frame 500 can be installed at the rear of the airbag 100 to install a license plate, a rear camera and / or a taillight, thereby meeting the vehicle's requirements for a license plate, a rear view and a rear display, and the setting of the fixing frame 500 can ensure the installation firmness of the license plate, the rear camera and the taillight. The fixing frame 500 can be a supporting sandwich carbon fiber plate structure, which has the advantages of light weight and high strength. The fixing frame 500 can be embedded with a mounting nut to meet the assembly requirements of the license plate, the rear camera and the taillight.

[0051] Further, see Figure 4 The plurality of warp cords 300 include a plurality of main warp cords 310. One end of the main warp cord 310 is fixed to one end of the airbag 100 close to the vehicle body 600, and the other end is fixed to the edge of the fixing frame 500. At the same time, the main warp cord 310 is set as an elastic cord, so that when the airbag 100 is deflated, the fixing frame 500 can be pulled to the middle area of ​​the rear of the vehicle body 600 under the tension of the main warp cord 310, so that the license plate installed on the fixing frame 500 is located in the middle area of ​​the rear of the vehicle body 600, which is more beautiful. Specifically, the fixing frame 500 can be set as a rectangular structure. On this basis, four main warp cords 310 are set, and one end of the four main warp cords 310 is respectively connected to the four corners of the fixing frame 500, so that the fixing frame 500 can be better positioned, so that the license plate installed on the fixing frame 500 can be set horizontally like a normal license plate after the airbag 100 is folded.

[0052] In addition, a power mechanism and a controller may be provided in the above-mentioned adjustable tail guide structure, and the controller is communicatively connected with the power mechanism so that the controller can control the power mechanism to drive the foldable guide member to open or fold, as follows:

[0053] A1, if the vehicle speed reaches a high threshold, the controller controls the driving mechanism to drive the foldable deflector to open, so as to reduce wind resistance, enable the vehicle to maintain stable and high-speed driving, and ensure vehicle driving safety. Specifically, the controller can choose to communicate with the vehicle's speed detection system so that the controller can directly obtain the vehicle's real-time speed from the speed detection system; of course, the controller can also choose to communicate with a separately added speed detection element so that the controller can obtain the vehicle's real-time speed from the added speed detection element. The above-mentioned high threshold can be set to 80km / h.

[0054] A2, if an opening instruction issued by the user is received, the controller controls the driving mechanism to drive the foldable guide member to open to meet the user's personalized needs.

[0055] A3, if the vehicle speed is lower than a low threshold, the controller controls the driving mechanism to drive the foldable deflector to fold, so as to reduce the size of the vehicle and facilitate merging and parking. The above low threshold can be set to 60km / h.

[0056] A4, if a folding instruction is received, the controller controls the driving mechanism to drive the foldable guide member to fold to meet the user's personalized needs.

[0057] A5, under the premise that the foldable deflector is elastic, if the foldable deflector includes an airbag 100, if there is a risk of rear-end collision, the controller controls the driving mechanism to drive the foldable deflector to open, so that the foldable deflector can absorb the collision energy generated when being rear-ended, play a buffering role, and improve the rear safety of the vehicle. In addition, when there is a risk of being rear-ended, the controller can also control the alarm to sound an alarm to remind the driver that he is about to be rear-ended. Specifically, the millimeter wave radar can be used to detect the distance and relative acceleration of the rear vehicle to determine whether there is a risk of being rear-ended.

[0058] Preferably, a pressure sensor may be provided in the airbag 100 of the foldable guide member, so as to sense the pressure value in the airbag 100 by using the pressure sensor, and the controller is communicatively connected with the pressure sensor so that the controller can control the power mechanism to drive the foldable guide member to open or fold according to the pressure value in the airbag 100 sensed by the pressure sensor, as follows:

[0059] B1, the controller can control the power mechanism to inflate or exhaust the airbag 100 according to the vehicle speed and the pressure value sensed by the pressure sensor, so as to adjust the size of the airbag 100 after opening, so that the size of the airbag 100 can change with the vehicle speed, so as to reduce the air pressure in the airbag 100 as much as possible on the basis of ensuring the airbag 100's gas diversion effect, so as to extend the service life of the airbag 100. In fact, when the vehicle speed is within a certain preset range (such as: 60km / h to 80km / h), the size of the airbag 100 will change with the change of the vehicle speed. When the vehicle speed exceeds the range (less than 60km / h or greater than 80km / h), the size of the airbag 100 will no longer change; that is, when the vehicle speed reaches more than 80km / h, the airbag 100 is expanded to the maximum.

[0060] B1.1 When the vehicle speed increases, the size of the airbag 100 should be increased to improve the airbag 100's gas diversion effect and reduce wind resistance. At this time, the controller can control the power mechanism to inflate the airbag 100, and at the same time, obtain the air pressure value in the airbag 100 sensed by the pressure sensor in real time. When the obtained pressure value rises to the pressure value corresponding to the vehicle speed, the power mechanism is controlled to stop inflating.

[0061] B1.2 When the vehicle speed slows down, the controller can control the power mechanism to pump air into the airbag 100, and at the same time, obtain the air pressure value in the airbag 100 sensed by the pressure sensor in real time. When the obtained pressure value drops to the pressure value corresponding to the vehicle speed, the power mechanism is controlled to stop pumping air.

[0062] B2, if the pressure value sensed by the pressure sensor is lower than the pressure threshold, it indicates that the airbag 100 is likely to be scratched at this time, and the controller controls the power mechanism to pump air into the airbag 100 to ensure driving safety.

[0063] The driving mechanism may be an electric air pump valve group.

[0064] See also Figure 1-Figure 3 This embodiment also provides a vehicle, which includes a vehicle body 600 and the above-mentioned adjustable rear air guide structure, and the adjustable rear air guide structure is installed at the rear of the vehicle body 600.

[0065] Preferably, a storage groove can be opened at the rear part of the vehicle body 600, and the above-mentioned adjustable rear air guide structure can be stored in the storage groove, so as to minimize the influence of the adjustable rear air guide structure on the overall length of the vehicle. The overall length of the vehicle can be maintained at the original length, and the overall length of the vehicle will not be lengthened due to the addition of the adjustable rear air guide structure, thereby improving the aesthetics of the vehicle.

[0066] See also Figure 1 , Figure 2 and Figure 6 A rear door 610 that can be flipped up and down can be provided at the rear of the vehicle body 600 , and on this basis, the above-mentioned adjustable rear deflector structure can be installed on the rear door 610 .

[0067] A display is provided in the cab of the vehicle body 600, and on this basis, the display is communicatively connected to the controller of the adjustable rear deflector structure, and the display can be used to display the status of the above-mentioned foldable deflector to let the driver know the status of the rear of the vehicle.

[0068] The shape of the vehicle body 600 may be set to a teardrop shape to reduce wind resistance.

[0069] The above-mentioned vehicle may be a small or micro vehicle.
