Abstract
The invention relates to a sealing method of an electric power steering controller. The sealing method of the electric power steering controller involves a base, a shell, a plastic framework, a circuit board, sealing rings and some connecting components. With the sealing method, the electric power steering controller can be comprehensively sealed in a waterproof mode, and meanwhile the cooling problem of the controller is solved. The sealing method is mainly designed on the basis of 360-degree closed sealing gaskets and the interface sealing rings. The 360-degree closed sealing gaskets are placed on the joint between the base and the plastic framework and the joint between the shell and the plastic framework, and the interface sealing rings are placed on external interfaces.
Description
Technical field
The present invention relates to a kind of encapsulating method of electric booster steering controller, in brief, aim to provide a kind of effective encapsulating method realizing comprehensive waterproof for electric booster steering controller exactly.
Background technology
Electric booster steering device, as the important component part of automobile, receives much concern all the time and studies widely.Electric booster steering device (Electric Power Steering, abbreviation EPS) be the power steering system that a kind of direct dependence motor provides auxiliary torque, compared with traditional hydraulic power-assist steering system HPS (Hydraulic Power Steering), EPS have reduce fuel oil consumption, operational stability and returnability good, be easy to the advantages such as maintenance.EPS is primarily of compositions such as torque sensor, car speed sensor, electrical motor, speed reduction gearing and electronic control units (ECU).Its principle of work is as follows: first, and torque sensor is measured chaufeur and applied operating torque on the steering wheel, and car speed sensor measures the current moving velocity of vehicle, then by these two signal transmission to ECU; ECU, according to built-in control policy, calculates desirable target assist torque, is converted into current-order to motor; Then, the assist torque that motor produces through speed reduction gearing amplification, overcomes steering resisting torque, realizes turning to of vehicle on mechanical type steering swivel system together with the operating torque of chaufeur.Core as electric booster steering controller one of forms, and ECU is the arithmetic center of whole system, and therefore the Performance And Reliability of ECU is most important.Due to electron component characteristic, waterproof and dampproof performance is for very important electric booster steering controller.
Controller can be operated in operator's compartment, also can be operated in engine bin.The controller of current design is operated in operator's compartment mostly, requires lower to classification of waterproof.As worked in engine bin, environment is relatively more severe, and often there will be the phenomenons such as water pouring, water logging, if controller is non-watertight, controller very easily damages.In order to ensure that controller also can normally work under this harsh environment, comprehensively waterproof and dampproof design is absolutely necessary.
Summary of the invention
The object of the invention is to: realize that a kind of structure is simple, with low cost, reliable operation, comprehensive hermetically-sealed construction for electric booster steering controller.
For achieving the above object, the present invention proposes a kind of encapsulating method of electric booster steering controller, the realization of the method is made up of base, plastic skeleton, packing seal and shell.It is characterized in that: electric booster steering controller entirety adopts seal ring design, discharges water, to ensure circuit card safety in order to comprehensive.
For achieving the above object, the present invention adopts upper and lower 360 ° of circulating type packing seals and full waterproof connector design.
360 ° of circulating type packing seal sealings are all adopted between shell and plastic skeleton and between base and plastic skeleton, 4, exterior angle fixed bit is outside circulating type packing seal, both secured shell and plastic skeleton and base and plastic skeleton, ensured again that water can not immerse plastic skeleton from shell or base.
Interface and the injection moulding of plastic skeleton integral type, in interface sealing joint pad design, anti-sealing enters in plastic skeleton from interface.
More than invention reaches the object of comprehensive waterproof, succinctly easy, convenient and practical.

Nomenclature: 1-base; 2-shell; 3-plastic skeleton; 4-circuit card; 5-packing seal; 7-screw; 8-interface; 9-sealing joint circle
Specific implementation
Referring to accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, by 1-base, 2-shell, 3-plastic skeleton, 4-circuit card, 5-packing seal and some links form the structure of electric booster steering controller sealing system.4-circuit card is screwed on 3-plastic skeleton, realizes the fixing of 4-circuit card.5-packing seal is positioned in seal groove special above 3-plastic skeleton, covers 2-shell, with 4 screws, 2-shell and 3-plastic skeleton are fixed.5-packing seal is positioned in seal groove special below 3-plastic skeleton, 1-base is connected with 3-plastic skeleton, be fixed with 4 screws, solve controller heat dissipation problem simultaneously.1-base and 2-shell is connected with screw.
As shown in Figure 2, eight symmetrical up and down 7-screws are utilized to realize the connection of 3-plastic skeleton and 1-base, 2-shell, utilize 5-seal ring front elevation to realize airtight waterproof, notice are as follows: 1, packing seal should adopt 360 ° totally-enclosedly to design without seam formula; 2, reserved on the space that produces after should connecting higher than 3-plastic skeleton and 1-base, 2-shell of packing seal height and 3-plastic skeleton groove sum; 3,5-packing seal shape is octagon, and when meeting 7-screw, crossingly to process near the limit of 7-screw with other both sides being 135 ° respectively, length, slightly larger than 7 screwhole diameters, prevents moisture from corroding 4 circuit cards by 7-screw in this way.
As shown in Figure 3,8-interface, utilize 9-sealing joint circle to achieve a butt joint the waterproof of mouth, it is characterized in that being close to interface inwall, height a little more than interface card slot, and adopts two-stage stepped design.
In sum, present invention achieves the comprehensive water-proff packing to electric booster steering controller, and method is succinct, practical, there is higher realistic meaning.
