Obviously, the described embodiments are one of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment 1:

[0032] Please refer to Figures 1 to 5, an embodiment of the present utility model provides a pneumatic suspension lifting tail wing, which includes a tail wing body 1, and further includes a lifting drive mechanism 2 installed on the tail wing body 1, tail wing wind wheels 3 installed on one side or both sides of the tail wing body 1, and a power transmission mechanism 4 installed on the tail wing wind wheels 3 and used to drive the lifting drive mechanism 2 to reciprocate up and down. The lifting drive mechanism 2 includes a support seat 20 installed on the tail wing body 1, a rotating shaft 21 inserted into the support seat 20, an inflatable airbag 22 installed on one side of the rotating shaft 21 and used to drive the rotating shaft 21 to rotate, a first lifting assembly 23 installed at one end of the rotating shaft 21, and a second lifting assembly 24 installed at the other end of the rotating shaft 21. The power transmission mechanism 4 includes a generator 41 installed on the tail wing wind wheel 3 and an air inflating pump 42 installed on the generator 41 and communicated with the inflatable airbag 22. There is an air valve switch connected between the generator 41 and the inflatable airbag 22.

[0033] Among them, a rotating connection plate 220 is installed on the above-mentioned inflatable airbag 22. The rotating connection plate 220 is installed on one side of the rotating shaft 21. The movement stroke of the rotating connection plate 220 is only an angle. Therefore, the cooperation between the inflatable airbag 22 and the rotating connection plate 220 can easily complete the reciprocating rotation drive of the rotating shaft 21.

[0034] Among them, the above-mentioned air inflating pump 42 is a prior art. Among them, the air inflating pump 42 has two implementation manners:

[0035] The first implementation manner of the air inflating pump 42 is: an electric air pump, which is a prior art; that is, when the generator 41 is started, while controlling the air valve switch to close, it also controls the electric air pump (driven by electricity) to inflate the inflatable airbag 22, and finally the tail wing body 1 is lifted; (For the specific operation principle of the electric air pump, refer to the Chinese utility model patent with the patent number: CN219622855 and the patent name: A low-noise steady-flow diaphragm pump body structure).

[0036] The second implementation manner of the air inflating pump 42 is: a rotary air pump, which is a prior art; that is, when the generator 41 is started, the rotary air pump is driven to rotate at the same time. The rotation of the rotary air pump will pump air into the inflatable airbag 22, and finally the tail wing body 1 is lifted; (For the specific operation principle of the rotary air pump, refer to the Chinese utility model patent with the patent number: CN219622855 and the patent name: A low-noise steady-flow diaphragm pump body structure. The rotary air pump is improved on the basis of this structure of a low-noise steady-flow diaphragm pump body structure, that is, a low-noise steady-flow diaphragm pump body structure omits the motor, and its eccentric wheel is directly coaxially connected with the shaft of the generator 41 in this embodiment 1).

[0037] The first lifting assembly 23 includes a first swing arm rod assembly 231 clamped to one end of the rotating shaft 21 and a first vehicle connection seat 232 hinged to the other end of the first swing arm rod assembly 231. The first vehicle connection seat 232 is used to be installed on one side of the vehicle tail. The first lifting assembly 23 further includes a first tail wing connection seat 233 installed on one side of the tail wing body 1. One end of the rotating shaft 21 passes through the first tail wing connection seat 233, and a first connecting rod assembly 234 is connected between the first tail wing connection seat 233 and the first vehicle connection seat 232. Among them, the two first swing arm rods of the first swing arm rod assembly 231 are respectively located at both ends of the first tail wing connection seat 233, and the two first connecting rods of the first connecting rod assembly 234 are respectively located at both ends between the first tail wing connection seat 233 and the first vehicle connection seat 232. The operating principle of the first lifting assembly 23 is as follows: by rotating one end of the rotating shaft 21, it drives one end of the first swing arm rod assembly 231 to rotate. However, the first vehicle connection seat 232 at the other end of the first swing arm rod assembly 231 is fixedly installed on the vehicle. Therefore, the other end of the first swing arm rod assembly 231 is fixed, and one end of the first swing arm rod assembly 231 rotates in compliance with the rotation of one end of the rotating shaft 21, and the first swing arm rod assembly 231 swings, causing one side of the tail wing body 1 to lift up. The first tail wing connection seat 233 and the first connecting rod assembly 234 play an auxiliary connection role, making the movement relationship between the tail wing body 1 and the first vehicle connection seat 232 smoother and the connection more convenient.

[0038] The second lifting assembly 24 includes a second swing arm rod assembly 241 clamped to the other end of the rotating shaft 21 and a second vehicle connection seat 242 hinged to the other end of the second swing arm rod assembly 241. The second vehicle connection seat 242 is used to be installed on the other side of the vehicle tail. The second lifting assembly 24 further includes a second tail wing connection seat 243 installed on the other side of the tail wing body 1. The other end of the rotating shaft 21 passes through the second tail wing connection seat 243, and a second connecting rod assembly 244 is connected between the second tail wing connection seat 243 and the second vehicle connection seat 242. The operating principle of the second lifting assembly 24 is as follows: by rotating the other end of the rotating shaft 21, it drives one end of the second swing arm rod assembly 241 to rotate. However, the second vehicle connection seat 242 at the other end of the second swing arm rod assembly 241 is fixedly installed on the vehicle. Therefore, the other end of the second swing arm rod assembly 241 is fixed, and one end of the second swing arm rod assembly 241 rotates in compliance with the rotation of the other end of the rotating shaft 21, and the second swing arm rod assembly 241 swings, causing the other side of the tail wing body 1 to lift up. The second tail wing connection seat 243 and the second connecting rod assembly 244 play an auxiliary connection role, making the movement relationship between the tail wing body 1 and the second vehicle connection seat 242 smoother and the connection more convenient.

[0039] Among them, the first vehicle connection seat 232 and the second vehicle connection seat 242 are adhered to the vehicle tail by 3M stickers or other adhesive materials.

[0040] The tail wing wind wheel 3 includes a cylindrical housing 31, a drive shaft 32 (not shown in the drawings) inserted into the cylindrical housing 31, and at least one guide vane 33 (not shown in the drawings) sleeved on the drive shaft 32.

[0041] The output shaft of the generator 41 is coaxially connected to the drive shaft 32, and the air inflation pump 42 is installed at one end of the motor.

[0042] A first air pipe is connected between the air inflation pump 42 and the air inflation balloon 22.

[0043] A second air pipe is connected between the air inflation balloon 22 and the air valve switch.

[0044] Among them, the first air pipe, the air valve switch, and the second air pipe (shown in the drawings) can be internally connected to the tail wing body 1 or externally connected to the tail wing body 1 (when connected to the air inflation balloon 22, it can pass through the tail wing body 1 through the installation hole). Figure 3 In the drawings) can be internally connected to the tail wing body 1 or externally connected to the tail wing body 1 (when communicating with the air inflation balloon 22, it can pass through the tail wing body 1 through the installation hole).

[0045] For a pneumatic suspension lifting tail wing of the present utility model, its operating principle is as follows:

[0046] A. When the vehicle travels to a certain speed, the vehicle flow causes the tail wing wind wheel 3 to rotate, thereby driving the generator 41 to rotate. The generator 41 is thus started. The generator 41 controls the air valve switch to close. At the same time, the generator 41 controls the air inflation pump 42 to inflate the air inflation balloon 22 (if the air inflation pump 42 is an electric air pump, the generator 41 simultaneously controls the electric air pump to inflate; if the air inflation pump 42 is a rotary air pump, the rotation of the tail wing wind wheel 3 also drives the rotary air pump to rotate and inflate). Finally, the air inflation balloon 22 drives the rotating shaft 21 to rotate, thereby driving the first lifting assembly 23 and the second lifting assembly 24 to lift, and finally driving the pneumatic suspension lifting tail wing of the present utility model to lift;

[0047] For example: When the vehicle travels at a speed of 40 yards to 100 yards, the pneumatic suspension lifting tail wing gradually lifts. The greater the pressure of the wind flow on the guide vane 33 of the tail wing wind wheel 3, the more sufficient the air inflated by the air inflation pump 42 into the air inflation balloon 22, and the greater the lifting angle of the pneumatic suspension lifting tail wing.

[0048] B. When the pneumatic suspension lifting tail wing of the present utility model descends, the air valve switch needs to be opened for ventilation, and it has two working modes:

[0049] The first one: non-external connection type. When the vehicle stops, the motor does not generate electricity at this time, causing the air valve switch to open, making the second air pipe conduct, causing the air inflation balloon 22 to deflate, and causing the pneumatic suspension lifting tail wing to descend. This working mode has a better decorative effect, making the tail wing of the vehicle often fluctuate during the traffic process;

[0050] The second type: An external control device is connected to the vehicle console. The control device is powered by a battery and is electrically connected to the air valve switch through a wire or a wireless protocol. The control device facilitates the user to independently control when the rear wing descends.

[0051] A pneumatic suspension lift rear wing of the present utility model has the following advantages: It does not need to be connected to the vehicle circuit for power supply. During driving, it can generate electricity through the wind flow and drive the rear wing to lift and lower, so it can be adapted to all vehicles, with a wide vehicle type adaptability. At the same time, between vehicle startup and vehicle stop, there can be visual effects of automatic rear wing lifting, rear wing undulating, and rear wing descending, and its decorative effect is good.

[0052] Embodiment 2:

[0053] The difference between a pneumatic suspension lift rear wing in Embodiment 2 and a pneumatic suspension lift rear wing in Embodiment 1 lies in: There is only a difference in the installation and connection relationship between the generator 41 and the air pump 42, and their functional principles are the same, so they will not be elaborated.

[0054] As Figure 6 shown, a pneumatic suspension lift rear wing includes a rear wing body 1, and further includes a lift drive mechanism 2 installed on the rear wing body 1, rear wing wind wheels 3 installed on both sides of the rear wing body 1, and a power transmission mechanism 4 installed on the rear wing wind wheels 3 and used to drive the lift drive mechanism 2 to reciprocate up and down. The lift drive mechanism 2 includes a support seat 20 installed on the rear wing body 1, a rotating shaft 21 inserted into the support seat 20, an inflatable airbag 22 installed on one side of the rotating shaft 21 and used to drive the rotating shaft 21 to rotate, a first lift assembly 23 installed at one end of the rotating shaft 21, and a second lift assembly 24 installed at the other end of the rotating shaft 21. The power transmission mechanism 4 includes a generator 41 installed on one of the rear wing wind wheels 3 and an air pump 42 installed on the other rear wing wind wheel 3 and communicated with the inflatable airbag 22. A gas valve switch is connected between the generator 41 and the inflatable airbag 22.

[0055] Among them, a rotating connection plate 220 is installed on the above-mentioned inflatable airbag 22. The rotating connection plate 220 is installed on one side of the rotating shaft 21. The movement stroke of the rotating connection plate 220 is only an angle. Therefore, the cooperation between the inflatable airbag 22 and the rotating connection plate 220 can easily complete the reciprocating rotation drive of the rotating shaft 21.

[0056] Among them, the above-mentioned air pump 42 is a prior art, and the air pump 42 has an implementation method:

[0057] The first embodiment of the inflatable pump 42 is: a rotary air pump, which is a prior art; that is, when the guide vane 33 of one of the tail wing rotors 3 rotates, it drives the rotary air pump to rotate at the same time. The rotation of the rotary air pump will pump air onto the inflatable airbag 22, and finally lift the tail wing body 1; (For the specific operation principle of the rotary air pump, refer to the Chinese utility model patent with the patent number: CN219622855 and the patent name: A low-noise and steady-flow diaphragm pump body structure. The rotary air pump is improved on the basis of the structure of this low-noise and steady-flow diaphragm pump body structure, that is, the motor is omitted from the low-noise and steady-flow diaphragm pump body structure, and its eccentric wheel is directly coaxially connected to the shaft of the generator 41 in Embodiment 1.)

[0058] The first lifting assembly 23 includes a first swing arm rod assembly 231 clamped at one end of the rotating shaft 21 and a first vehicle connection seat 232 hinged to the other end of the first swing arm rod assembly 231. The first vehicle connection seat 232 is used to be installed on one side of the vehicle tail. The first lifting assembly 23 further includes a first tail wing connection seat 233 installed on one side of the tail wing body 1. One end of the rotating shaft 21 passes through the first tail wing connection seat 233, and a first connecting rod assembly 234 is connected between the first tail wing connection seat 233 and the first vehicle connection seat 232. Among them, the two first swing arm rods of the first swing arm rod assembly 231 are respectively located at both ends of the first tail wing connection seat 233, and the two first connecting rods of the first connecting rod assembly 234 are respectively located at both ends between the first tail wing connection seat 233 and the first vehicle connection seat 232. The operation principle of the first lifting assembly 23 is: by the rotation of one end of the rotating shaft 21, it drives the rotation of one end of the first swing arm rod assembly 231. However, the first vehicle connection seat 232 at the other end of the first swing arm rod assembly 231 is fixedly installed on the vehicle. Therefore, the other end of the first swing arm rod assembly 231 is fixed, and one end of the first swing arm rod assembly 231 rotates in compliance with the rotation of one end of the rotating shaft 21, and the first swing arm rod assembly 231 swings, causing one side of the tail wing body 1 to lift. The first tail wing connection seat 233 and the first connecting rod assembly 234 play an auxiliary connection role, making the movement relationship between the tail wing body 1 and the first vehicle connection seat 232 smoother and the connection more convenient.

[0059] The second lifting assembly 24 includes a second swing arm rod assembly 241 clamped to the other end of the rotating shaft 21 and a second vehicle connecting seat 242 hinged to the other end of the second swing arm rod assembly 241. The second vehicle connecting seat 242 is used to be installed on the other side of the vehicle tail. The second lifting assembly 24 further includes a second tail wing connecting seat 243 installed on the other side of the tail wing body 1. The other end of the rotating shaft 21 penetrates through the second tail wing connecting seat 243, and a second connecting rod assembly 244 is connected between the second tail wing connecting seat 243 and the second vehicle connecting seat 242. The operating principle of the second lifting assembly 24 is as follows: by the rotation of the other end of the rotating shaft 21, one end of the second swing arm rod assembly 241 is driven to rotate. However, the second vehicle connecting seat 242 at the other end of the second swing arm rod assembly 241 is fixedly installed on the vehicle. Therefore, the other end of the second swing arm rod assembly 241 is fixed, and one end of the second swing arm rod assembly 241 rotates in compliance with the rotation of the other end of the rotating shaft 21, causing the second swing arm rod assembly 241 to swing, so that the other side of the tail wing body 1 is lifted. The second tail wing connecting seat 243 and the second connecting rod assembly 244 play an auxiliary connection role, making the movement relationship between the tail wing body 1 and the second vehicle connecting seat 242 smoother and the connection more convenient.

[0060] Among them, the first vehicle connecting seat 232 and the second vehicle connecting seat 242 are adhered to the vehicle tail by 3M stickers or other adhesive materials.

[0061] Both of the two tail wing wind wheels 3 include a cylindrical shell 31, a driving shaft 32 (not shown in the drawings) inserted into the cylindrical shell 31, and at least one guide vane 33 (not shown in the drawings) sleeved on the driving shaft 32.

[0062] The output shaft of the generator 41 is coaxially connected to the driving shaft 32 of one of the tail wing wind wheels 3, and the air inflation pump 42 is a rotary air pump, and its rotary air pump is coaxially connected to the driving shaft 32 of the other tail wing wind wheel 3.
