Embodiment 1

[0024] figure 1 and figure 2 Among them, a shock-absorbing structure capable of driving the ejection of the vehicle body includes an energy storage chamber, the energy storage chamber includes a housing 10 and a cavity located in the housing 10, the housing 10 is in the shape of a cylinder, and the energy storage chamber is provided with The piston rod 106 is slidingly arranged relative to the energy storage chamber, and the lower end of the piston rod 106 is provided with a piston 105 that cooperates with the inner wall of the energy storage chamber. The piston 105 is provided with the side of the piston rod 106, that is, the lower side of the piston 105 forms a pressure chamber 11 with the housing 10 of the energy storage chamber, and the upper side of the piston 105 forms a flat pressure chamber 14 with the housing 10 of the energy storage chamber. The side wall at the upper end of 14 is provided with a flat pressure hole 141 communicating with the outside world. The cro...

Embodiment 2

[0026] A shock-absorbing structure that can drive the ejection of the car body, such as image 3 The difference between the illustrated embodiment 2 and the embodiment 1 is that the piston rod 106 is a two-stage structure, which is divided into an upper piston rod 1061 and a lower piston rod 1062, the piston 105 is fixed on the upper end of the upper piston rod 1061, and the upper piston rod A damping spring 183 is provided between the rod 1061 and the lower piston rod 1062 . The side wall of the housing 10 of the accumulator chamber is only provided with a single air release valve assembly. The lower end of the housing 10 is provided with a protrusion for setting the vent hole 100 . The shell 10 of the energy storage chamber is a spliced ​​structure of two halves, and the two half shells 10 are airtightly connected by screws of an enamel mounting ring 101 . Both the piston 105 and the piston rod 106 are cylinders, and the inner wall of the energy storage chamber is also a c...

Embodiment 3

[0028] A shock-absorbing structure that can drive the ejection of the car body, such as Figure 4 The difference between the illustrated embodiment 3 and the embodiment 2 is that: the upper piston rod 1061 is provided with an airtight buffer chamber 19, the buffer chamber 19 is hourglass-shaped, and the buffer chamber 19 includes two elliptical cavities, The two cavities are vertically arranged up and down, and the two cavities are connected through the constriction. The axis of the buffer chamber 19 is coaxial with the piston rod 106. The buffer chamber 19 is provided with an energy-dissipating liquid 191 whose volume is smaller than that of the buffer chamber. 19 in volume. When the piston 105 vibrates, the energy-consuming fluid 191 in the two cavities vibrates, and flows back and forth in the two cavities through the constriction. When flowing through the constriction, due to the reduction of the flow cross-section, the energy-consuming fluid 191 changes from a slower spee...

Abstract

The invention discloses a shock-absorbing structure capable of driving a car body to be ejected, which comprises an energy storage chamber, on which a one-way valve that can only enter air is provided, and on the energy storage chamber, an adjustable safety valve and an air release gate are also provided. Assemblies, the energy storage chamber is provided with a piston rod slidably arranged relative to the energy storage chamber, one end of the piston rod is provided with a piston cooperating with the inner wall of the energy storage chamber, and the energy storage chamber is provided with an ejection spring cooperating with the piston. The invention is beneficial in that it can complete the ejection of the electric vehicle, facilitate the electric vehicle to cross steps, road pits or ride on curbs, etc., facilitate the driving and parking of the electric vehicle, without external ejection power, simple structure and high reliability; Good ejection stability.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a shock-absorbing structure capable of driving the vehicle body to eject. Background technique [0002] Electric vehicles have become more and more popular short-distance scooter due to their advantages of less space constraints, low cost and easy parking. However, existing electric vehicles may need to go up steps or curbs during parking and driving. In some cases, lifting electric vehicles obviously requires certain physical strength and physical fitness. The existence of this situation has caused great inconvenience to the use of electric vehicles and has restricted the further development of electric vehicles. No one in the prior art proposes a solution to the problem of how the electric vehicle saves effort on steps and avoids road obstacles. [0003] Therefore, it is just necessary to design a shock-absorbing structure that can drive the ejection of the car body for an electric veh...
