Description
Technical field
The utility model relates to vehicle component field, in particular to a kind of air-conditioner temperature pressure sensor.
Background technique
Presently used air-conditioner temperature pressure sensor is generally divided into temperature sensor and pressure sensor two states.It is existing
There is the sensor for having the following deficiencies: that 1. pressure sensors are pressure switch formula in technology, is controlled by induction high pressure and low pressure
Compressor switch processed, low efficiency be easy to cause power dissipation.2, temperature sensor is typically mounted inside evaporator, induction essence
It is poor to spend, and cools down when reaching a certain level, and needs to shut down compressor, otherwise will cause frost.3, split type temperature passes
Sensor and pressure sensor are unfavorable for system data acquisition and control, and power dissipation is serious, is unsuitable for the application of new energy vehicle.
Because to avoid disadvantages described above, need a kind of structure simple and low cost, at the same detect in air-conditioning duct temperature and
The sensor device of pressure.
Utility model content
In view of this, that the purpose of this utility model is to provide a kind of probe positioning accuracies is high, it is steady to simplify technique, performance
Determine, improve production efficiency, while metal probe and outer casing bottom can realize the air-conditioner temperature pressure sensor of sealing.
Air-conditioner temperature pressure sensor provided by the utility model, including shell, the temperature sense being set in the shell
Answer element and pressure responsive element, and the communication plug connecting with the temperature sensitive member and pressure responsive element signal；
The temperature sensitive member includes head and bar portion；The head of the temperature sensitive member is located in shell, and bar portion is stretched out outer
The front end face of shell；The pressure responsive element is round pressure chip, is located at head and the communication plug of temperature sensitive member
Between front end face；
Further, inner seal rings I, temperature are equipped between the head front end and case nose inner wall of the temperature sensitive member
It spends and is equipped with inner seal rings II between the head rear end and pressure chip money end face of sensing element；
Further, gasket is equipped between the pressure chip and communication plug；
Further, the case nose forms flange, and the flange sleeve has external sealing ring.
The utility model has the beneficial effects that
The air-conditioner temperature pressure sensor of the utility model, can be applied to the sensing of new-energy automobile heat pump air conditioning system
Device is integrated with the function of pressure detecting in air-conditioning duct temperature detection and pipeline in one, passes through the temperature in detection air-conditioning duct
Degree and pressure, and it is real-time transmitted to air-conditioning system, the switch of compressor is controlled by air-conditioning system, the utilization of resources is abundant, to new
The power source saving of energy vehicle has great promotion.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the explosive view of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
As illustrated in fig. 1 and 2, the air-conditioner temperature pressure sensor of the present embodiment, including shell 6, be set in the shell 6
Temperature sensitive member and pressure responsive element, and connect with the temperature sensitive member and pressure responsive element signal logical
Letter rack head 1；The temperature sensitive member includes head and bar portion；PTC positive temperature coefficient heat is equipped in the temperature sensitive member
The head of quick resistance, temperature sensitive member is located in shell 6, and bar portion stretches out the front end face of shell 6；The pressure responsive element
For round pressure chip 3, it is located between 1 front end face of head and communication plug of temperature sensitive member.This temperature pressure sensing
Device can be applied to the sensor of new-energy automobile heat pump air conditioning system, is integrated with pressure in air-conditioning duct temperature detection and pipeline and examines
The function of survey by the temperature and pressure in detection air-conditioning duct, and is real-time transmitted to air-conditioning system, by air-conditioning system in one
The switch of compressor is controlled, the utilization of resources is abundant, have great promotion to the power source saving of new energy vehicle.
In the present embodiment, inner sealing is equipped between 6 front inner wall of head front end and shell of the temperature sensitive member
I 5 are enclosed, inner seal rings II is equipped between 3 front end face of head rear end and pressure chip of temperature sensitive member, passes through inner sealing
Circle may insure the sealing performance inside sensor outer housing 6.
In the present embodiment, gasket 2 is equipped between the pressure chip 3 and communication plug 1；
In the present embodiment, 6 front end of shell forms flange, and the flange sleeve has external sealing ring 7.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention；It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on are included in the protection scope of the present invention.
