Example 1

A two-wheeled vehicle pneumatic stand as shown in fig. 1-9, comprising: a housing 1 and a cylinder 2 which are fixedly connected with a vehicle body 8; the body of the air cylinder 2 is rotationally connected with the shell 1; a support column 3 is fixedly arranged at the driving end of the air cylinder 2; a guide rod 4 is further arranged on the support column 3; a first guide groove 5 and a second guide groove 6 which are oppositely arranged are arranged in the shell 1; the middle part and the bracing piece fixed connection of guide bar 4, the both ends of guide bar 4 slide respectively and set up in the inside of first guide way 5 and the inside of second guide way 6.

In order to make people more labor-saving when parking, and not need to laboriously lift the vehicle, the utility model provides a pneumatic control rear wheel support, in particular to a pneumatic control rear wheel support, wherein a cylinder 2 is rotatably arranged in a shell 1, a guide rod 4 is slidably arranged in the shell 1, so that when a driving end of the cylinder 2 extends out, the guide rod 4 slides in a guide groove to drive the cylinder 2 to rotate, and when the cylinder 2 rotates to the lowest, the guide rod 4 can also extend downwards in a vertical direction for a distance to enable a wheel 9 to be lifted upwards in situ. As will be appreciated by those skilled in the art, the use of the present apparatus to raise the wheels 9 requires that a rear wheel support be provided on each side of the rear wheel so that the rear wheel can be raised smoothly. By adopting the wheel 9 supporting device provided by the utility model, the rear wheel of the vehicle can be automatically lifted in situ when people need to park, people do not need to lift the vehicle hard, and a rider with smaller strength can park conveniently. By adopting the utility model, the rear wheels of the vehicle can be lifted or lowered in situ at the parking position, the support of the vehicle can be rotated without additionally occupying parking space, and the space required by parking is smaller.

Optionally, the housing 1 includes: a top plate 11, a first side plate 12, and a second side plate 13; the top of the first side plate 12 and the top of the second side plate 13 are fixedly connected with the two side edges of the top plate 11 respectively; two sides of the body of the air cylinder 2 are respectively connected with a first side plate 12 and a second side plate 13 in a rotating way; the first guide groove 5 is formed on the inner side surface of the first side plate 12; the second guide groove 6 is formed on the inner side surface of the second side plate 13. Specifically, in the present utility model, the side plate may be fixedly connected to the vehicle body 8, or the top plate 11 may be fixedly connected to the vehicle body 8, which should be understood by those skilled in the art, and all alternatives are within the scope of the present utility model.

Alternatively, as shown in fig. 7 and 8, the first guide groove 5 includes: a first straight groove 51 and a first arc-shaped groove 52; the top end of the first straight groove 51 communicates with the bottom end of the first arc groove 52, and the radius of the first arc groove 52 gradually decreases in the upward direction. Optionally, the second guide groove 6 includes: a second straight groove 61 and a second arc-shaped groove 62; the top end of the second straight groove 61 communicates with the bottom end of the second arc groove 62, and the radius of the second arc groove 62 gradually decreases in the upward direction.

In particular, the first guide groove 5 and the second guide groove 6 need to be mirror images. If only the simple requirement is that the wheels 9 are lifted away from the ground, the mode of arranging the straight-up and straight-down air cylinders 2 can be directly adopted, when the driving ends of the air cylinders 2 extend, the supporting rods contact the ground, the wheels 9 leave the ground, and when the air cylinders 2 retract, the wheels 9 fall back to contact the ground. Since the vehicle body 8 is inclined when the two-wheeled vehicle turns, the vertically disposed support bar affects the traveling of the vehicle when the vehicle turns. In order to avoid the influence, the utility model also arranges an arc groove above the straight groove, and the arc groove is used for enabling the supporting rod to rotate to a position close to the horizontal along the arc groove under the condition that the air cylinder 2 is retracted, so that the influence of the supporting rod on the running of the vehicle can be reduced as much as possible.

Optionally, a first rotary bearing 41 and a second rotary bearing 42 are also included; the inner ring of the first rotary bearing 41 is fixedly connected with one end of the guide rod 4, and the inner ring of the second rotary bearing 42 is fixedly connected with the other end of the guide rod 4; the first rotary bearing 41 is accommodated inside the first guide groove 5, and the second rotary bearing 42 is accommodated inside the second guide groove 6. The tip of guide bar 4 can directly set up and make a round trip to slide in the guide way, because guide bar 4 is under the condition of stretching out or retracting, needs to form spacingly with the mutual butt of the lateral wall of guide way, consequently set up the bearing at the tip of guide bar 4, can reduce the frictional force between guide bar 4 and the guide way, improve the life of equipment.

Optionally, the bottom of bracing piece still fixedly is provided with supporting legs 7. The supporting feet 7 can enlarge the contact area between the supporting rod and the ground, and improve the supporting firmness of the vehicle.

Specifically, in fig. 9, the double connection lines are shown as gas pipes which are mutually communicated, and the single connection lines are shown as electric connection, and since the utility model adopts the cylinder 2 as a driving device, a driving device for driving the cylinder 2 to reciprocate is also required, the inflator pump is used for inflating the gas storage bottle, so that the gas in the gas storage bottle is in a high pressure state, the pressure sensing device is used for sensing the gas pressure in the gas storage bottle, and the inflator pump can inflate the gas storage bottle under the condition that the gas pressure in the gas storage bottle is reduced. The electromagnetic valve is used for controlling the flowing direction of gas in the gas storage bottle, the control button can control the electromagnetic valve to switch the gas transmission direction, and the electromagnetic valve can be controlled to switch the connection and conduction direction once every time the electromagnetic valve is pressed, in the utility model, the cylinder 2 adopts the double-end acting cylinder 2, namely the extension and retraction of the cylinder 2 are all controlled by high-pressure gas, when the cylinder 2 extends, the high-pressure gas is input from the first input end of the cylinder 2, and when the cylinder 2 retracts, the high-pressure gas is input from the second input end of the cylinder 2. As will be appreciated by those skilled in the art, with a single-ended cylinder 2, only one input is required to be connected to the solenoid valve. The control device refers to a computing device capable of supporting commands according to a preset program, such as a singlechip, an MCU chip and the like, and the energy source of the utility model is mainly a battery of a motor vehicle. For the same unpowered two-wheeled vehicle, a battery can be additionally provided for power supply.

In summary, according to the utility model, the rotatable cylinder 2 is arranged in the housing 1, and the support rod is arranged at the driving end of the cylinder 2, so that the vehicle can be automatically lifted upwards when parked, and the rear wheel is separated from the ground, thereby completing the parking operation.
