Description
Technical field
The utility model relates to car accessories technical field, especially a kind of engine hall-effect speed sensor.
Background technology
At present, the speed probe that engine uses mainly contains two kinds: magnetoelectric tachometric transducer and hall-effect speed sensor, because the output signal of magnetoelectric sensor is for being similar to sinusoidal wave AC signal and output signal is very large by the impact of rotating speed, so the transducer market share of the mode of kind can be fewer and feweri.Contrary hall-effect speed sensor output signal is easy-to-handle pulse voltage signal, now hall-effect speed sensor connector commercially be substantially all with probe is integrated be injection-moulded in together with, due to the problem such as engine bin assembly space is limited and car load oscillation intensity is large, there will be the problem of losing signal.
Utility model content
The applicant for the shortcoming in above-mentioned existing production technology, provide a kind of with wire harness, vibration resistance assembles by force hall-effect speed sensor on the engine, adopts Split type structure design, increase buffering, reduce the vibrations of connector, installation and removal are convenient, are convenient to safeguard.
The technical scheme that the utility model adopts is as follows:
A kind of engine hall-effect speed sensor, comprise housing, the inside of described housing is provided with support, and described support is fixed with printed board, magnet steel and Hall chip respectively, above-mentioned be in place after at the inner chamber embedding glue of housing; Also comprise cable, enclosure interior is stretched in one end of described cable, and it is connected by wire and printed board, and the other end of described cable stretches out housing, and installs three core connectors at its other end, and described three core connectors overlap flexible sheath.
Its further technical scheme is:
Described three core connectors are connected with Engine ECU.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, compact, easy for installation, the utility model is connected with Engine ECU by three core connectors, the related datas such as Real-time Collection engine speed, by calculating the current oil spout of engine and fired state, and by this signal transmission to oil spout and ignition module, enable engine oil spout accurately and igniting, car load normally works.Thus the control achieved engine output torque, serve that engine is fuel-efficient, the object of vehicle-speed limit and vehicle emissions reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, Hall chip; 2, magnet steel; 3, printed board; 4, support; 5, wire; 6, housing; 7, cable; 8, flexible sheath; 9 three core connectors.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the engine hall-effect speed sensor of the present embodiment, comprises housing 6, and the inside of housing 6 is provided with support 4, support 4 is fixed with respectively printed board 3, magnet steel 2 and Hall chip 1, above-mentioned be in place after at the inner chamber embedding glue of housing 6; Also comprise cable 7, it is inner that housing 6 is stretched in one end of cable 7, and it is connected by wire 5 and printed board 3, and the other end of cable 7 stretches out housing 6, and install on three core connector 9, three core connectors 9 at its other end and overlap flexible sheath 8.
Three core connectors 9 are connected with Engine ECU.
Three core connectors 9 provide sensor voltage to interior, external transmission sensor signal.
The hall signal that sensor detects is transferred to ECU by the three core connectors 9 that anti-vibration ability is strong.
Three core plug-in units 9 described in the utility model overlap flexible sheath 8, and the oscillation intensity that flexible sheath 8 pairs of plug positions are born carries out damping.
Housing described in the utility model 6 pairs of inner components are fixed by encapsulating mode, improve the manufacturability of product.
The utility model can be applicable on engine cam, also can be applicable on engine crankshaft simultaneously.
Specific works process of the present utility model is as follows:
First vehicle-mounted 24V storage battery is 5V by ECU photovoltaic conversion, then 5V supply voltage is passed to Hall revolution speed transducer by three core connectors 9 by ECU, after car load starts, the gear signal of sensor meeting Real-Time Monitoring engine, and mechanical signal is converted into the pulse voltage signal being easy to identify, signal wheel often turns around, the quantity that sensor exports pulse equals the quantity that signal takes turns upper tooth or hole, the change moment of Hall voltage reflects the position of camshaft or bent axle, after ECU receives the output signal of sensor, the number of times of Hall voltage change in the unit interval can be can be calculated by inter-process, the rotating speed of engine can be reflected.
The utility model structure is simple, critical piece is arranged in a housing 6, by being with three core connectors 9 of wire harness as the interface with ECU, thus ensure that the convenience of installation, make can freely dismantle in the very limited nacelle in space, simultaneously also for the maintenance in later stage, maintenance provide conveniently.
Another advantage of the present utility model is that three core connectors 9 devise a resilient sheath in its structure, can play effective mitigation to the strong vibration of car load.As everyone knows, the environment for use of commercial car is more severe, during road bump may there is the phenomenon loosening instantaneously or depart from sensor and overall wire sheaves to interface place, and be a very large hidden danger concerning the speed probe of signal demand Real-time Collection and process, the utility model is on the basis summarizing sensor construction in the past, by knowing the real situation in divergent thinking, early stage and Multitest checking, and finally have developed this kind of speed probe through repeatedly optimizing, overcome existing product to rigidly fix interface, to the non-cushioned defect of strong vibration.
The utility model is connected with Engine ECU by three core connectors 9, the wheel speed signal of Real-Time Monitoring engine, and mechanical signal is changed into the pulse voltage signal being easy to identify and process, input to car load ECU, so that ECU is presented at the rotating speed of engine on panel board by calculating.In addition, this speed probe also identifies cylinder compression top dead centre for ECU, thus carries out sequential fuel injection control, time of ignition control and detonation control.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
