However, the electric bicycle has many defects, such as: the safety of lithium batteries still remains to be improved. The hidden danger of ignition, combustion and even explosion of the lithium battery cannot be completely eliminated at present. When a vehicle collides, the anode and cathode materials of the battery can break through the diaphragm, and when the energy is quickly recharged to the battery during braking, the battery is short-circuited and the temperature is increased due to the reasons of instantaneous ultrahigh current and the like, so that combustion and even explosion are caused. In addition, the electrolyte of the lithium ion battery is an organic electrolyte, and the substances are more easily ignited and burnt after contacting with air.
The environmental pollution caused by the discarded storage battery is serious in the aspect of environmental protection.
In order to overcome the defects of the electric power-assisted vehicle, people begin to research and develop a pneumatic power-assisted vehicle, namely a compressed air power-assisted vehicle, which drives the power-assisted vehicle to run by utilizing high-pressure compressed air. The electric moped does not consume fuel, is an environment-friendly moped with real zero emission, can effectively relieve the serious urban air pollution and the lack of petroleum resources, and solves the problems of slow energy storage of the electric moped and secondary pollution caused by a lead storage battery.
Although the existing pneumatic power-assisted vehicle can overcome the defects of air pollution and the like caused by the existing electric power-assisted vehicle, the existing pneumatic power-assisted vehicle supplies air to the pneumatic power device through the air storage bottle, the air supply mode is similar to adiabatic expansion, the overall use efficiency of the air is low, and the cruising ability is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1 and 2, an embodiment of the present invention provides a novel pneumatic power assisted vehicle 100/200, including:
a wheel 11 provided on the frame 10;
a pneumatic motor 15 for driving the wheel 11 to rotate;
a connecting pipe 12 connected between the pneumatic motor 15 and the tubular bracket 102; and
a pressure reducing valve 13 and a valve 16 provided on the connecting pipe 12.
The tubular support 102 is not limited in structure and shape, and on one hand, the tubular support plays a role in supporting, and on the other hand, the tubular support utilizes the structure of the frame 10 to store air, so that the integral cruising ability is improved. The tubular stent 102 may be formed integrally with the gas storage structure, or formed partially with the gas storage structure, or may be arranged according to actual needs, which will not be described in detail herein. The air pressure of the tubular support 102 may be selected according to the endurance requirement, for example, greater than or equal to 1 MPa. However, it will be clear to the skilled person that the higher the gas pressure per unit volume, the greater the endurance, but the higher the requirements for gas tightness and strength of the tubular stent 102. Therefore, the gas pressure of the tubular holder 102 may be preferably 1MPa to 20 MPa.
The frame 10 may further include an air reservoir 101 in communication with the tubular bracket 102 or an air reservoir 101 independently disposed with respect to the tubular bracket 102. The gas storage tubes 101 may be disposed in parallel and spaced apart on the tubular bracket 102, for example, the gas storage tubes 101 may be disposed transversely on the tubular bracket 102 or longitudinally on the tubular bracket 102. In order to make the gas storage tubes 101 have a large gas storage space in a unit volume and to make the heat absorption between the gas storage tubes 101 good. It is necessary to control the pipe diameter of the gas bomb 101 and the interval between the gas bombs 101. Defining the distance between the air storage pipes 101 to be H, and the pipe diameter of the air storage pipes 101 to be R, wherein the ratio of R to H is 10-60: 1. More preferably, the ratio of R to H is 40-50: 1, because the air storage pipe 101 of the pneumatic power-assisted vehicle 100/200 is generally exposed to air, and thus has a good heat absorption area. In one embodiment, the distance H between the air reservoirs 101 is 1mm, and the diameter R of the air reservoirs 101 is 40mm, so that the air can expand approximately isothermally when entering the pneumatic engine 15, thereby improving the efficiency of the pneumatic engine 15.
As a further refinement, the vehicle frame 10 may further include an air reservoir 14 in communication with the tubular bracket 102. Specifically, the air storage tank 14 may be detachably connected or fixed to the air storage pipe 101 or the tubular bracket 102, so as to further improve the endurance of the whole lift. More preferably, the air reservoir 14 may communicate with the tubular support 102 via an air reservoir 101, such that air absorbs heat through the tubular support 102 to achieve isothermal expansion.
The pneumatic engine 15 can refer to CN201821336081.2CN201710458557.3 or other types of pneumatic engines, and details are not repeated herein; CN201821336081.2CN201710458557.3 are also within the scope of the present disclosure. The position of the pneumatic engine 15 is not limited, and may be selected according to actual needs, for example, the pneumatic engine 15 may be disposed on the rear wheel of the novel pneumatic moped 100/200 and directly drive the rear wheel; the pneumatic engine 15 can be arranged in the middle of the novel pneumatic moped 100/200 and drives a chain of the novel pneumatic moped 100/200; alternatively, the pneumatic engine 15 may be provided on the front wheel of the new pneumatic booster vehicle 100/200 to directly drive the front wheel.
Referring to fig. 2, in one embodiment, the pneumatic engine 15 is disposed in the middle of the frame 10 of the new pneumatic booster vehicle 100/200 and is used for driving the chain thereof.
In a further improvement, the pressure reducing pressure of the pressure reducing valve 13 is 0.2MPa to 1 MPa. In one embodiment, the pressure relief pressure of the pressure relief valve 13 is about 0.3 MPa.
In one embodiment, the valve 16 is disposed between the pressure reducing valve 13 and the pneumatic motor 15, so that the valve 16 is prevented from being damaged by high-pressure gas.
In one embodiment, the new pneumatic assisted vehicle 100/200 further comprises a pressure sensor (not shown) for acquiring the pressure of the tubular bracket 102. It can be understood that the pressure sensor can be used for acquiring the gas quantity of the tubular bracket 102 and/or the gas storage pipe 101, and further acquiring the remaining stroke of the novel pneumatic moped 100/200.
Referring to fig. 3, an embodiment of the present invention further provides a control method of the novel pneumatic moped 100/200, including the following steps:
s1, acquiring the pressure of the tubular stent 102;
and S2, acquiring the driving distance of the novel pneumatic moped 100/200 according to the pressure of the tubular bracket 102.
In step S1, the pressure of the tubular stent 102 may be acquired by a pressure sensor provided in the tubular stent 102.
In step S2, the distance that the new pneumatic power-assisted vehicle 100/200 can travel needs to be converted according to the actual weight of the new pneumatic power-assisted vehicle 100/200, the efficiency of the pneumatic engine 15, and the pressure of the tubular bracket 102, and will not be described in detail herein.
In other embodiments, the control method further comprises:
and S3, when the pressure of the tubular stent 102 is lower than a first threshold value, giving an early warning.
The first threshold value may be set to be slightly higher than the relief pressure of the relief valve 13. In one embodiment, the first threshold is 0.35-0.4 MPa.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
