Abstract
The utility model discloses a sensor of a milometer, which comprises a casing. A rotating shaft is arranged in the casing, a plug is arranged on one side of the casing and provided with a circuit board assembly, a bearing is embedded between the rotating shaft and the casing, a magnetic steel is arranged on one side of the rotating shaft which extends into the casing, a sensing head is arranged on the circuit board assembly and matched with the magnetic steel, the bearing is sleeved on the upper portion of the rotating shaft, and a protruding disk arranged at the top of the bearing is matched with the casing. The bearing is arranged on the rotating shaft of the sensor of the milometer, and the other parts are not contacted with the inner wall of the casing, thereby reducing friction, enabling the operation to be stable, and prolonging service life of the novel sensor of the milometer. Simultaneously, the protruding disk which is arranged at the upper portion of the bearing is matched with the inner wall of the casing in shape, thereby being more compact in structure.
Description
Technical field
The utility model relates to a kind of car electrics spare, is specifically related to a kind of kilometer sensor.
Background technology
Kilometer sensor is a kind of car electrics spare commonly used, is the device that physical quantity is converted to electric signal, is widely used in each automobile industry.Existing kilometer sensor generally comprises housing and is arranged on the rotating part in the housing, and rotating part comprises rotating shaft, and rotating shaft is provided with magnet steel near an end of enclosure interior.This kilometer sensor in use moves not steady, influences the sensing effect.
Summary of the invention
The purpose of the utility model is: in order to overcome the deficiency of prior art, the utility model provides a kind of and has operated steadily, the kilometer sensor of long service life.
In order to realize above-mentioned purpose, the technical scheme below the utility model has adopted: a kind of kilometer sensor comprises housing; Be provided with rotating shaft in the described housing, a side of housing is provided with plug, and described plug is provided with circuit board module; Be inlaid with bearing between described rotating shaft and the housing, the side that rotating shaft is stretched in the housing is provided with magnet steel, and described circuit board module is provided with inductive head; Inductive head and magnet steel are equipped with; Bearing holder (housing, cover) is located at the top of rotating shaft, and the top portion of bearing is provided with protruding dish, with the shell setting.
As preferably, be provided with boss with cooperation place, bearing bottom in the described rotating shaft, be provided with bearing shim between bearing and the boss.After adopting above-mentioned preferred version, the bearing of the utility model, can be cooperated more reposefully in rotating shaft when rotating with rotating shaft.
As preferably, described bearing is an oiliness bearing.The oiliness bearing cost is low, can absorbing, noise is little, doing in the time than the farm labourer without characteristics such as apply oils; Be applicable to and be difficult for lubricated or do not allow the dirty working environment of oil; After adopting above-mentioned preferred version, the kilometer sensor of the utility model is practical more.
As preferably, described magnet steel bottom and rotating shaft cooperation place are provided with the magnet steel pad.After adopting above-mentioned preferred version, more steady when magnet steel is rotated along with rotating shaft.
As preferably, described circuit board module and shell place are provided with rubber sheet gasket.After adopting above-mentioned preferred version, circuit board module is played buffer protection function.
As preferably, described housing is provided with seal groove outward, is provided with the O RunddichtringO in the described seal groove.After adopting above-mentioned preferred version, when making the kilometer sensor of the utility model be installed on the automobile, and can form the setting that is sealed and matched, cooperate more tight with associated components.
The rotating shaft top of the kilometer sensor of the utility model is provided with bearing; Remainder does not contact with inner walls, has reduced friction force, moves more steady; Increased the serviceable life of the utility model kilometer sensor; Simultaneously the top of bearing is provided with protruding dish, is equipped with the inner wall shape of housing, and structure is more compact.
Description of drawings
Fig. 1 is the structural representation of the utility model mileometer.
Embodiment
As shown in Figure 1, the embodiment of the utility model specifically is a kind of kilometer sensor, comprises housing 1, is provided with rotating shaft 2 in the housing 1, and a side of housing 1 is provided with plug 3, and plug 3 is three slotting plugs.Plug 3 is provided with circuit board module 4, and circuit board module 4 is provided with rubber sheet gasket 5 with housing 1 cooperation place.Circuit board module 4 is provided with inductive head 6, is inlaid with bearing 8 between rotating shaft 2 and the housing 1, and bearing 8 is an oiliness bearing.The side that rotating shaft 8 is stretched in the housing 1 is provided with magnet steel 7, and magnet steel 7 bottoms and rotating shaft 2 cooperation places are provided with magnet steel pad 11.Inductive head 6 is equipped with magnet steel 7, and bearing 8 is sheathed on the top of rotating shaft 2, and the top portion of bearing 8 is provided with protruding dish 13, is equipped with housing 1.Be provided with boss with cooperation place, bearing 8 bottom in the rotating shaft 2, be provided with bearing shim between bearing and the boss.Housing is provided with seal groove 9 outward, is provided with O RunddichtringO 10 in the seal groove 9.
The principle of work of the kilometer sensor of the utility model is identical with the principle of work of the kilometer sensor of prior art, and difference is: the bearing 8 of the utility model is sheathed on the top of rotating shaft 2, has reduced friction force; Simultaneously the top of bearing 8 be provided with protruding dish 13, be equipped with the inner wall shape of housing 1, structure is more compact.
