Abstract
The utility model relates to an electronic oil pressure sensor, which comprises a shell and a joint base assembled and connected with the shell. An oil passage hole is arranged in the joint base. A filter screen is arranged above the oil passage hole of the joint base. A socket board is arranged above the filter screen. The socket board is positioned in the joint base. A circuit board with a piezoelectric sensor is arranged in the socket board. The piezoelectric sensor is opposite to the oil passage hole across the filter screen. The utility model solves the problems of multiple mechanical faults, bad anti-vibration performance and short service life of the common mechanical oil pressure sensor in the prior art. By the design, oil enters the electronic oil pressure sensor from the oil passage hole; and after the oil is filtered by the filter screen, the piezoelectric sensor can detect oil pressure so as to transmit the oil pressure to the circuit board. The electronic oil pressure sensor has the advantages of simple structure, convenient assembly, difficult wear, high measuring precision and stable and reliable performance.
Description
Technical field
The utility model relates to a kind of electronic type engine oil pressure pickup.
Background technology
Engine oil pressure pickup is the sensor that generally uses on automobile and diesel vehicle.Traditional engine oil pressure pickup all is a mechanical structure, its product design principle is to utilize the metallic membrane compressive deformation, promote cursor slide by a cover complicated mechanical devices and slide on slide wire resistance, the slide wire resistance value is changed, the electric current that changes the tensimeter coil is with detected pressures.The defective of its structural design is: because the plasticity and the reminiscence characteristic of sensing element metallic membrane, its stability and fatigue resistence are relatively poor; The slip plate portion adopts Φ 0.08 constantan wire, and brush is Φ 0.12 a silvery white copper, and this structure makes the wearing quality of line plate slipper relatively poor; Pressure alarm partly adopts the sliding contact form, and warning bulb cold-state resistance is very little, and the temporary impact electric current is very big, easily produces electric arc during frequent power on/off and burns out alarm actuating contact.The inadequate natural endowment of these designs, add influence of various factors such as engine manufacture level and road conditions, caused mechanical type engine oil pressure pickup mechanical fault many, as brush, slide wire resistance wearing and tearing and ablation, alarm actuating contact wearing and tearing, the anti-vibration performance is poor, standardization level is low, and serviceable life is short.
Summary of the invention
For the problem that mechanical fault is many, the anti-vibration performance is poor, serviceable life is short that overcomes standard machinery formula engine oil pressure pickup in the prior art, the utility model provides a kind of electronic type engine oil pressure pickup, this electronic type engine oil pressure pickup simple in structure, easy to assembly, not easy to wear, measuring accuracy is high, stable and reliable for performance.
The technical scheme that its technical matters that solves the utility model adopts is: comprise shell and the joint pedestal that is connected with the shell assembling, be provided with oil hole in the joint pedestal, it is provided with screen pack above the oil hole of joint pedestal, the screen pack top is provided with socket, socket is positioned in the joint pedestal, the circuit board of band piezoelectric sensor is set in the socket, and piezoelectric sensor is relative with oil hole across screen pack.
Be provided with groove in the socket, the circuit board of band piezoelectric sensor is installed in the groove.
Be provided with pad between socket bottom and the joint pedestal.
Screen pack is one deck, two-layer or multilayer.
The utility model is by above-mentioned specific design, machine oil is entered in the electronic type engine oil pressure pickup by oil hole, after the screen pack filtering, piezoelectric sensor can the machines oil pressure, thereby be transferred on the circuit board, have advantage simple in structure, easy to assembly, not easy to wear, that measuring accuracy is high, stable and reliable for performance.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model comprises shell 2 and the joint pedestal 5 that is connected with shell 2 assemblings, be provided with oil hole 6 in the joint pedestal 5, above the oil hole 6 of joint pedestal 5, be provided with screen pack 8, screen pack 8 is one deck, two-layer or multilayer, screen pack 8 tops are provided with socket 1, socket 1 is positioned in the joint pedestal 5, the circuit board 7 of band piezoelectric sensor 4 is set in the socket 1, the concrete plan of establishment of circuit board 7 can be to be provided with groove 9 in socket 1, and the circuit board 7 of band piezoelectric sensor 4 is installed in the groove 9.Piezoelectric sensor 4 is relative with oil hole 6 across screen pack 8.Be provided with pad 3 between socket 1 bottom and the joint pedestal 5, pad 3 plays the effect of adjusting socket 1 position.Under user mode, machine oil is entered in the electronic type engine oil pressure pickup by oil hole 6, and after screen pack 8 filterings, piezoelectric sensor 4 can the machines oil pressure, thereby is transferred on the circuit board 7.Above-described embodiment only is that the preferred implementation to the utility model electronic type engine oil pressure pickup is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain of the utility model electronic type engine oil pressure pickup.
