Abstract
The utility model discloses a throttle valve position sensor, which comprises a front cover (2) and a base (9) sealed with a front cover (2). A rotor (7) the winding shaft (1) of which is driven by a throttle valve shaft to rotate is arranged in the base (9). A torsional spring (5) resetting the rotor (7) is arranged outside the rotor (7). The inner side of the front cover (2) is provided with the circuit board (3) with a carbon diaphragm resistor disc. The upper end plane of the rotor (7) is provided with a brush (4) sliding on the carbon diaphragm resistor disc. The circuit board (3) is a hard printed circuit board. In the utility model, the circuit board with the carbon diaphragm resistor disc is arranged at the inner side of the panel, so the processing of products is facilitated and signal precision is improved.
Description
Technical field
The utility model relates to a kind of sensor, is specifically related to a kind of throttle position sensor.
Background technology
Existing throttle position sensor comprises panel, the base that matches with panel, drives the rotor that rotates by throttle plate pin, and the side surface of rotor is provided with brush, and brush contacts with the wiring board that is printed with carbon film resistance plate.The voltage and the earth lead that connect input, output on the wiring board by plug connector.Drive the rotation of rotor along with the rotation of throttle plate pin, and then brush is mobile on resistor disc, exports different magnitudes of voltage, to show the diverse location at throttle plate pin place.
But this structure has its weak point: because brush is arranged on the side surface of rotor, therefore wiring board can only be soft board bending, that be centered around peritrochanteric, this is inconvenience concerning processing, and after throttle sensor advanced long-time the use, the precision of detection can be affected.
The utility model content
The purpose of this utility model provides a kind of throttle position sensor easy to process.
To achieve these goals, by the following technical solutions:
A kind of throttle position sensor, comprise cover and the base that is sealed and matched mutually with cover, be provided with in the base by throttle plate pin and drive the rotor that pivots, rotor exterior is provided with the torsion spring that rotor is resetted, it is characterized in that: the inboard of described cover is provided with the wiring board that has carbon film resistance plate, and the upper surface of described rotor is provided with sliding brush on carbon film resistance plate.
In order to improve the precision of processing, be convenient to processing, described wiring board is a hard printed circuit board.
Sway for the ease of rotor, the outer face of described rotor is provided with the pit that inside has bowl-shape rotary sleeve, described pit and rotary sleeve interference fit; Described axle is arranged at the lower surface of cover, and the concave surface that passes wiring board and rotary sleeve joins.
In order to make the rotary sleeve self-lubricating, the material of described rotary sleeve adopts Teflon.
In order to guarantee the sealing of rotor and base, be provided with sealing gasket between the housing of described rotor and base.
The beneficial effects of the utility model are:
(1) the utility model wiring board that will have a carbon film resistance plate is arranged on the inboard of panel, has made things convenient for the processing of product.
(2) owing to be provided with the rotary sleeve of self-lubricating material, make rotor smooth more when rotating, improved the precision of signal.
(3) because wiring board is a hard printed circuit board, reduce the cost of product, improved the precision that detects, made things convenient for the production of product.
