Abstract
The utility model relates to a vacuum control sensor belonging to the vehicle electrical product. The vacuum control sensor comprises a joint, a small spring, a shell, a sealing plate, a coil strip core tube assembly, a diaphragm, a tube seat, a filter, a big spring and an upper cover. The sealing plate, the coil strip core tube assembly and the small spring are arranged in the shell and are led out through a socket to form the electrical control contact of the vacuum control sensor; and the big spring, the diaphragm and the upper cover are connected with the shell in a press fit way to form the tail gas input contact of the vacuum control sensor. The utility model can solve the problems that the mechanical contact sensor has high contact resistance and is prone to poor contact, the parts of the mechanical contact sensor can be rusted and the like.
Description
Technical field
The utility model relates to a kind of automobile electrical appliances product, is a sensor, a kind of specifically vacuum control sensor.
Background technique
Existing domestic seldom vehicle is used automobile exhaust gas recirculating system (EGR), and corresponding supporting product sensor is not developed yet, and does not have matured product.But along with the development of Domestic Automotive Industry, when more and more higher, the parts of automobile exhaust gas recirculating system (EGR) will obtain more applications to the requirement of motor vehicle emission.Vacuum control sensor is used for automobile exhaust gas recirculating system (EGR), is as a control unit in the automobile exhaust gas recirculating system, is core component.Vacuum control sensor belongs to the contact type sensor, be similar to switch control, and contact type sensor in the past is mechanical contact mostly, there is the part corrosion, contact resistance is big, occurs faults such as bad connection easily, is not suitable for using in the automobile exhaust gas recirculating system.
Summary of the invention
Technical problem to be solved in the utility model is: the shortcoming at above prior art exists, a kind of vacuum control sensor is proposed, and can solve the part corrosion, contact resistance is big, occurs the problem of bad connection easily.
The technological scheme that the utility model solves above technical problem is:
Vacuum control sensor, comprise joint, little spring, shell, sealing plate, coil belt carcass pipe assembly, barrier film, base, filter, big spring and loam cake; Sealing plate, coil belt carcass pipe assembly and little spring install in the enclosure, draws by plug, forms the contact of the electrical equipment control of sensor; Big spring, barrier film and loam cake adopt to be press-fitted with shell and link to each other, and form the tail gas input contact of sensor.Joint and shell adopt ultrasonic welding.
Under the situation that does not have vehicle exhaust input and electrical equipment control, sealing plate and barrier film are under the support of large and small spring, be in off position, no matter this moment, sensor was imported the vacuum of much pressure, the sensor delivery outlet communicates with external atmosphere pressure all the time, be output as barometric pressure numerical value, the control of not imported.When control port input vehicle exhaust, pressure value reaches certain numerical value, make the barrier film action, the pressure that overcomes spring contacts with base, stops up base, this moment, delivery outlet and external atmosphere pressure disconnected, communicate with the inlet opening, make the certain vacuum value of sensor output, this vacuum values is delivered to next stage, thereby the action of control next stage assembly makes system be in normal working.When access+13.5V supply voltage, the force disconnect of sensor gas passageway reaches the work of artificial control system in addition.
The utility model can solve the part corrosion that the mechanical contact-type sensor exists, and contact resistance is big, occurs problems such as bad connection easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the rear view of Fig. 1.
Embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, Fig. 2 is the rear view of Fig. 1, vacuum control sensor comprises joint 1, little spring 2, shell 3, sealing plate 4, coil belt carcass pipe assembly 5, barrier film 6, base 7, filter 8, big spring 9 and loam cake 10; Sealing plate 4, coil belt carcass pipe assembly 5 and little spring 2 are installed in the shell 3, draw by plug, form the contact of the electrical equipment control of sensor; Joint 1 adopts ultrasonic welding with shell 3, with anti-gas-leak; Big spring 9, barrier film 6 adopt to be press-fitted with shell 3 with loam cake 10 and link to each other, and form the tail gas input contact of sensor.
The A mouth connects the input vacuum, it is the vacuum-pressure signal of motor, the B mouth is a sensor delivery pressure signal, the C mouth is the vehicle exhaust pressure signal, K to electrical connector between during access+13.5V voltage, produce electric current by coil, with the effect of core pipe, play the effect of electromagnet, make the sealing plate action, middle silicone rubber partly stops up the vent of core pipe, the gas of A mouth input can't be transmitted, no matter this moment, vehicle exhaust added great pressure, no matter also the A mouth is imported much pressure vacuums, the B mouth is no-output all the time.When not feeding voltage, when C mouth input vehicle exhaust, pressure value reaches certain numerical value, make barrier film 6 actions, the pressure that overcomes big spring 9 contacts with base 7, stops up base 7, this moment, B mouth and external atmosphere pressure disconnected, communicate with the A mouth, make the certain vacuum value of sensor output, go to control the action of next stage assembly.
The utility model is under the situation that does not have vehicle exhaust input and electrical equipment control, sealing plate 4 and barrier film 6 are under the support of big spring 9 and little spring 2, be in off position, no matter this moment, sensor was imported the vacuum of much pressure, the sensor delivery outlet communicates with external atmosphere pressure all the time, be output as barometric pressure numerical value, the control of not imported.When control port input vehicle exhaust, pressure value reaches certain numerical value, make barrier film 6 actions, the pressure that overcomes spring contacts with base 7, stops up base 7, this moment, delivery outlet and external atmosphere pressure disconnected, communicate with the inlet opening, make the certain vacuum value of sensor output, this vacuum values is delivered to next stage, thereby the action of control next stage assembly makes system be in normal working.When access+13.5V supply voltage, the force disconnect of sensor gas passageway reaches the work of artificial control system in addition.
The utility model can also have other mode of execution, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
