Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figures 2 and 3, the utility model module of gas saving valve for mini engine is made up of throttle body assembly 11 and the intake air temperature sensor 5, throttle position sensor ceramic substrate 7, air inlet pressure sensor 8, stepper motor 6 and the pcb board 40 that are arranged in the housing.Described housing comprises housing assembly 10 and cover plate 1.Outer side wall respectively is provided with an engaging projection 20 around the described housing assembly 10, and clip 2 is fastened on cover plate 1 and engages between the projection 20, and housing assembly 10 and cover plate 1 are fixed together, and can carry out dismounting, maintenance very easily like this.Extend to form surrounding edge 17 under all side direction of cover plate 1, this surrounding edge 17 is suitable with the shape of housing assembly 10, and housing assembly 10 is coated.Like this when cover plate 1 with after housing assembly 10 is fixedlyed connected, formed sealing configuration can prevent effectively that greasy dirt, water or other fouls from entering enclosure interior.Particularly when carwash, can prevent effectively that the high pressure water of high pressure water gun ejection from entering in the housing, cause internal sensor and circuit board damage, influence its reliability, simultaneously this sealing means maintainalbility can be good, and dismounting is very convenient.
Sides in this housing assembly 10 are provided with stepper motor 6, and the left end of the opposite side relative with stepper motor 6 is provided with throttle position sensor ceramic substrate 7, and its right-hand member is provided with pcb board 40.Pcb board 40 is provided with flush type copper cash 41, and pcb board 40 is electrically connected with the welding of stepper motor 6 by flush type copper cash 41 and welded post 61; Pcb board 40 is electrically connected with the welding of throttle position sensor ceramic substrate 7 by flush type copper cash 41 and solder joint 71.Throttle position sensor rotor 3 is arranged between throttle position sensor ceramic substrate 7 and the pcb board 40, and directly is connected with throttle plate pin.
Air inlet pressure sensor 8 pasters are at the back side of pcb board 40, and the other end of air inlet pressure sensor 8 is close on the bottom end of housing assembly 10, are provided with one with the bottom end of its corresponding shell assembly 10 and detect the hole, and this detection hole is connected with the closure air flue.The detection hole of described air inlet pressure sensor below also can be communicated with the force samples hole on being arranged on throttle body assembly 11, is used to gather the pressure at other positions of automobile with small output volumn.
The back side of pcb board 40 is provided with the intake air temperature sensor 5 that is electrically connected with it.Be provided with a mounting hole in the housing assembly 10, the thermistor of intake air temperature sensor 5 is installed in this hole and the closure air flue.Direct and the pcb board electrical connection of air inlet pressure sensor, the direct and pcb board electrical connection of stepper motor.
Described housing assembly 10 and pcb board 40 corresponding side outer ends are directly made the standard male end socket of contact pin more than by the method for quadric injection mould, and as input/output interface, this interface is electrically connected with pcb board 40.The user just can be connected with client end is convenient by the female end of a standard, and interface is very succinct, convenient.
