Embodiment Construction

[0009] The non-contact photoelectric sensor of automobile fuel capacity is composed of a float frame 1, a shading plate 2, a float rod 3, a light source 5, a photoresistor 9, and a float 16. The float frame 1 is connected with a fixed photoresistor 9 and a light source 5 . The light source 5 can be one, two, or several (closely arranged) light-emitting diodes (LEDs) welded together and made into a specific emission light (surface).

[0010] figure 2 It is the embodiment of this invention: 1 is the buoy frame, which is reformed on the existing buoy frame, on which the buoy bar 3 hinged holes are set, the elliptical connecting hole of the light source 5 can be moved up and down, the lower limit end 10, the upper limit End 17, the fixed barb 11 of photoresistor 9, and the connecting terminal of lead 12,13,14,15, 5 is light source, is provided with connection hole on it, positive pole circuit 6, negative pole circuit 7, and light-emitting diode (LED) is welded on On its circuit...

Abstract

An automobile fuel volume non-contact photoelectric sensor is made by the characteristic that a photoresistance varies according to the variation of the strength and the irradiation area of light. When the fuel is in a full state, a float 16 is located in the top position, a shading plate 2 hardly shades light emitted from a light source 5, and the photoresistance is minimum; when the fuel reduces, the shading plate 2 decreases correspondingly to shade corresponding light ray of the light source 5, and the photoresistance increases correspondingly; and when the fuel deceases to an empty state, the shading plate 2 is located in the lowest position and nearly shades all light ray of the light source 5, and the photoresistance is maximum and designed to be null.

Description

Technical field: [0001] The invention belongs to the technical field of automobile fuel control, in particular to a non-contact photoelectric sensor for automobile fuel capacity Background technique: [0002] The existing fuel oil quantity sensor is a contact sliding resistance type. Due to the existence of contact sliding, sliding wear occurs, and the wear causes the contact surface to change or even break away from contact. Contact wear is the main cause of damage to this type of sensor, resulting in early damage to the sensor and a high failure rate. High and difficult to repair. Invention content: [0003] The present invention is a non-contact sensor designed for the defects of the above-mentioned contact sensor. The non-contact photoelectric sensor is designed with extremely low calorific value, light-emitting diode (LED) as the light source (other light-emitting parts can also be used), and the characteristics of the photoresistor changing correspondingly to the in...
