Abstract
The utility model discloses an electric power-assisted steering system shell for protecting internal electronic elements. The shell is provided with a plurality of water dripping holes; and the water dripping holes are positioned in the shell which is provided with a large quantity of internal electronic elements. When the humidity and temperature differences are large in an entire automobile environment, condensed water is produced easily in the shell, so that normal work and the service life of internal electronic elements of the shell are influenced. After the water dripping holes are formed, produced condensed water can flow out of the shell successfully through the water dripping holes, so that the internal electronic elements are protected.
Description
Technical field
The utility model relates to a kind of device of automobile technical field, and specifically, what relate to is a kind of electric boosting steering system housing for the protection of internal electronic element.
Background technology
Electric boosting steering system (Electric Power Steering, abbreviation EPS) is the developing direction of automobile steering system.This system directly provides power steering by electric boosted machine, has saved the necessary power steering oil pump of hydraulic power steering system, flexible pipe, hydraulic oil, belt conveyor and has been loaded on belt pulley on the driving engine, has both saved energy, has protected again environment.In addition, also have the characteristics that adjustment is simple, assembling is flexible and power steering can both be provided under multiple situation.Electric boosting steering system and traditional hydraulic power-assist steering system HPS(Hydraulic Power Steering) compare, the EPS system has lot of advantages.EPS mainly is comprised of torque sensor, car speed sensor, electrical motor, speed reduction gearing and electronic control unit (ECU) etc.
When chaufeur turns at the steering dish, torque sensor detects the size of turning to of steering handwheel and torque, voltage signal is transported to electronic control unit, torque voltage signal, rotation direction and vehicle speed signal etc. that electronic control unit detects according to torque sensor, send instruction to motor controller, make electrical motor export the power steering torque of corresponding size and Orientation, thereby produce auxiliary power.When automobile did not turn to, electronic control unit did not send instruction to motor controller, and electrical motor is not worked.
Because relate to a lot of electronic components; electric boosting steering system protects these original papers not to be subjected to influence of moisture by housing; but except entering steam, the outside can affect the damage of ECU internal electronic element; in the car load environment; when humidity, when the temperature difference is larger, easily produce condensed water, thereby also can affect normal operation and the life-span of internal electronic element; and might cause circuit card to be burned, cause vehicle and personal safety.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of electric boosting steering system housing for the protection of internal electronic element is provided.
For realizing above-mentioned purpose, the electric boosting steering system housing (hereinafter to be referred as housing) for the protection of internal electronic element described in the utility model arranges a plurality of weepers on the described housing.
Further, described weeper is positioned at the many housing places of internal electronic element.
Further, described weeper can be two or more also, depends on actual needs.
Further, described weeper is positioned at the edge of housing.
Further, if weeper is arranged on the seal casinghousing, then described weeper place can arrange sealing plug.
Further, described sealing plug can adopt the materials such as general plastics or rubber, is mainly used in guaranteeing the leak tightness of shell.
In the car load environment, when humidity, when the temperature difference is larger, easily produce condensed water in the electric boosting steering system housing, thereby affect normal operation and the life-span of enclosure interior electronic component.The utility model when condensed water produces, makes condensed water wherein can flow out smoothly housing through weeper, with the protection internal electronic element by above-mentioned weeper is set.
The utility model is simple in structure, and is easy to use, and technique realizes also simple, improved the reliability of automobile, normal operation and the life-span of protection internal electronic element, vehicle and the personal safety also avoiding so cause.The utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1, the present embodiment provides a kind of electric boosting steering system housing for the protection of internal electronic element, and this servo steering system is steering tube pillar electric boosting steering system, is positioned at vehicle drive indoor.Five weepers 1,2,3,4,5 are set on the described electric boosting steering system housing.These five weepers 1,2,3,4,5 lay respectively at front and back and the left and right sides of housing.
In the present embodiment, described five weepers 1,2,3,4,5 diameter are 4mm.
In the present embodiment, described five weepers 1,2,3,4,5 are positioned at the many housing places of internal electronic element.
In the present embodiment, described weeper is positioned on the housing, and is better, is positioned at the housing edge.Certainly, this will be according to actual needs and the situation of position and deciding.
In the present embodiment, better, if weeper is arranged on the seal casinghousing, then described weeper place need to arrange sealing plug.
In the present embodiment, described sealing plug adopts rubber seal plug, and its shape is identical with the weeper shape, guarantees the leak tightness of housing.
In the car load environment, when humidity, when the temperature difference is larger, easily produce condensed water in the electric boosting steering system housing, thereby affect normal operation and the life-span of enclosure interior electronic component.The utility model when condensed water produces, makes condensed water wherein can flow out smoothly housing through weeper, with the protection internal electronic element by above-mentioned weeper is set.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
Claims (4)
1. the electric boosting steering system housing for the protection of internal electronic element is characterized in that arranging on the described housing a plurality of weepers.
2. the electric boosting steering system housing for the protection of internal electronic element according to claim 1 is characterized in that: described weeper is positioned at the many housing places of internal electronic element.
3. the electric boosting steering system housing for the protection of internal electronic element according to claim 2, it is characterized in that: described weeper is positioned at the edge of housing.
