Vacuum pipeline clamp for electric automobile

Abstract

A vacuum pipeline clamp for an electric automobile comprises a nylon self-locking binding belt, an arc nylon auxiliary binding head and a binding belt holding force measurement alarm assembly. The binding belt holding force measurement alarm assembly comprises a pressure sensor, a battery, a loudspeaker, an adjusting switch and a mounting plate. the battery, the loudspeaker, the adjusting switch and the pressure display are all installed on the mounting plate, the pressure sensor is electrically connected with the loudspeaker, the adjusting switch and the battery in series through wires, the pressure display is connected with the pressure sensor in parallel, and the pressure display displays the deformation degree of the pressure sensor by measuring the voltage between the two wire outletends of the pressure sensor. According to the vacuum pipeline clamp for the electric automobile, the balance of tightening of the vacuum pipeline near the binding head part and other parts of the tightening belt can be improved; according to the vacuum pipeline clamp for the electric automobile, the binding force can be reasonably controlled through the binding belt holding force measurement alarmassembly, the leakage-proof reliability is improved, the durability of the leakage-proof function can be improved, and therefore the vacuum pipeline clamp for the electric automobile is very excellent.

Description

technical field [0001] The invention relates to an intelligent vacuum pipeline clip for an electric vehicle. Background technique [0002] The vacuum boosting effect of the braking system is related to the driving safety of the car. In the automobile brake booster system, because the vacuum booster cannot obtain vacuum or the vacuum obtained is insufficient, the boosting effect of the brake system will be poor. The electric vacuum pump can monitor the change of vacuum in the booster through the vacuum sensor, so as to ensure that the driver can provide sufficient boosting effect under various working conditions. [0003] Electric vehicles are driven by electric motors, which cancel the traditional engine, so they lose the source of vacuum, that is, they cannot provide vacuum boost for the brake master cylinder of the car. The electric vehicle electric vacuum pump is produced to make up for this deficiency. It uses the vehicle power supply to provide power, and pushes the m...

Problems solved by technology

The previous Chinese patent did not reveal the corresponding clamp technology. In fact, the traditional vacuum pipeline clamps used now are made of metal materials, and the strain of the material itself is used to clamp the vacuum tubes. However, once the clamps are made, the specifications Fixed, and the hardness of the rubber of the vacuum tube will vary with different manufacturers, which will easily cause the problem of either the card is too tight or the card is not tight.

If the card is too tight, it is easy to cause permanent deformation of the rubber, resulting in air leakage, and if the card is not tight, it is also easy to leak air
