Problems solved by technology

[0002] Two-wheeled bicycles, motorcycles and electric vehicles are very convenient small means of transportation, and they are also very stable when riding. The disadvantage is that the speed should not be too low when riding. Use your feet to touch the ground or support it left and right to help the electric car start or stop slowly
Standing up the electric car is also a troublesome thing. At this time, it is necessary to use hands and feet together to support the rear frame and stabilize the electric car.

Embodiment 1

[0021] Such as figure 1 , figure 2 , image 3 Shown is an electric landing gear and landing wheels that can be raised and lowered.

[0022] Below the landing gear that can be raised and lowered is a flat-fork swing rod 10 with one end movably connected to the body and one end that can swing up and down. A landing wheel 1 is installed in the flat fork fork of the flat-fork swing rod 10. The steel ring side of the landing wheel 1 is The ratchet wheel 2 formed by several ratchet teeth and connected with the steel ring as a whole. At the position close to the ratchet wheel 2, a fixed vertical rod 12 fixedly connected to the horizontal fork swing rod 10 is erected on the flat fork swing rod 10, and the fixed vertical rod 12 A little behind, there is a swinging pole 11 that is movably connected to the flat-fork pendulum rod 10 and can swing back and forth. The top of the swinging pole 11 is a set of curved extension struts 6 that can drive the flat-fork pendulum rod 10 to swing up and ...

Embodiment 2

[0027] Such as Figure 4-12 Shown is an electric vehicle stamped and formed from a thin plate. Under the belly on the left and right sides of the electric vehicle, there are a set of landing wheels 1 and 15 that are lifted and lowered by a landing gear. Such as Figure 4 , Image 6 It is a diagram of the landing wheels 1 and 15 on the left and right sides being lifted. Such as Figure 7 , Picture 9 It is a diagram showing the landing wheels 1 and 15 on the left and right sides descend to the ground. Such as Picture 10 , Picture 12 It is a diagram showing the landing wheels 1 and 15 on the left and right sides land and the rear wheel 4 is raised.

Embodiment 3

[0029] Such as Figure 13 Shown is a pneumatic speed sensor. On the axles of the front or rear wheels of the electric vehicle, or on the side of the wheel, there is a set of fan blades 23 like a blower, a pneumatic speed sensor 25 driven by wheels, a pneumatic speed sensor 25 The outer shell 22 is opened with a damper 19 that communicates with the inside and the outside. The damper 19 is covered with a layer of pneumatic membrane 21 that can be inflated by wind. Just outside the pneumatic membrane 21 is a micro switch 20 that can be inflated by the pneumatic membrane 21. The movable switch 20 is connected to the motor 9 again. It is also possible to install a wind-driven door leaf 24 at the door opening of the air door 19. Outside the door leaf 24 is a micro switch 20 that can be pressed by the door leaf. The micro switch 20 is then connected to the motor 9.

Abstract

The invention discloses electric landing gears and a pneumatic speed sensor. The two sets of electric landing gears driven by motors are arranged on the left and right sides of an electric car correspondingly, and landing wheels are arranged on the lower parts of the landing gears; the motors rotate screws and nuts, flexion-extension supporting rods drive flat fork swinging rods and the landing wheels to ascend and descend, and stabilization of the electric car at the low speed is kept through the left and right landing wheels; and the pneumatic speed sensor is assembled on the front or rear wheel axle of the electric car to sense the magnitude of the car speed and control left and right rotation of the motors and taking-off and landing of the landing wheels.

Description

Technical field [0001] The invention relates to a vehicle, a landing gear and a pneumatic speed sensor for an electric vehicle. Background technique [0002] Two-wheeled bicycles, motorcycles, and electric vehicles are very convenient small vehicles, and they are also very stable when riding. The disadvantage is that the speed cannot be too low when riding. If the speed is low, the palm is not easy to hold. You must use your feet or support left and right to help the electric car start or stop slowly. It is also more troublesome to stand up an electric vehicle. At this time, you need to use your hands and feet together to support the rear frame and stabilize the electric vehicle. Is it possible to use something like two feet to support it when needed, and to lift the rear wheel of the electric vehicle and stand firmly. Now, there is a patent application (application number: 201510967015X) that provides an electric vehicle stamped and formed from a thin plate. The body shell of ...
