Hybrid electric vehicle gas cylinder for capable of potentiometer type detecting relative displacement in potentiometer type

Abstract

The invention provides a hybrid electric vehicle gas cylinder for capable of potentiometer type detecting relative displacement in a potentiometer type. The hybrid electric vehicle gas cylinder for potentiometer type detecting relative displacement comprises an outer shell, an inner shell, a controller and a display terminal, wherein a cavity is formed between the outer shell and the inner shell; the cavity is filled with buffer fillers are filled in the cavity; the outer shell is connected with the inner shell through a buffer spring; a relative displacement sensor and the controller are also arranged in the cavity. Compared with the prior art, the hybrid electric vehicle gas cylinder has the following beneficial effects that through arranging the outer shell and the inner shell, the structure firmness is good, and the connection strength is good; with the buffer fillers and the buffer spring, the impact force can be effectively absorbed, and the damage of rigid impact on the inner shell is avoided; through arranging the relative displacement sensor, the displacement situation of the inner shell inside the outer shell can be detected, and workers can detect whether the buffer fillers and the buffer spring work normally or not according to the displacement information and then judges whether the buffer fillers and the buffer spring need to be replaced or not, so that the personal safety of passengers in an vehicle is further ensured.

Description

technical field [0001] The invention relates to a gas cylinder of a hybrid electric vehicle with a potentiometer type for detecting relative displacement, and relates to a power source of the hybrid electric vehicle. Background technique [0002] In order to protect the ecological environment, adjust the energy structure and meet the requirements of strict emission indicators, automobile manufacturers have introduced a series of hybrid electric vehicles. There are many power sources for hybrid electric vehicles: batteries, generators, and combustible gas. The use of clean combustible gas instead of gasoline and diesel as vehicle fuel has developed relatively maturely. [0003] For example, Chinese patent literature discloses a gas supply device for automobiles [application number: 200620086652.2; authorized announcement number: CN200940523Y], which includes a gas storage tank, a conduit, an evaporation regulator and a gas nozzle, and the gas storage tank passes through The ...

Problems solved by technology

This structure has higher requirements for the impact strength of the bracket and the hoop. During a high-speed collision, the hoop will come into contact with the safety valve and pressure valve on the gas cylinder when a side collision occurs, which may cause gas leakage; When a rear collision occurs, the gas cylinder has a huge backward inertial force, causing the gas cylinder bracket to fail, and the gas cylinder may collide with the rear of the vehicle at high speed, causing excessive force on the gas cylinder and causing an explosion hazard; The huge forward inertial force causes the bracket connection to be destroyed, which is very likely to cause an impact on the rear seats, causing injury to the occupants or damage to the gas cylinder. The current installation structure of the gas cylinder has a relatively large safety hazard
