Description
Technical field
The present invention relates to a kind ofly for the power-assisted steering electric-controlled box on automobile, belong to frame for movement technical field.
Background technology
Power-assisted steering electric-controlled box is requisite part in Electric Power Steering Control System, by lineRoad plate, base plate, cover plate and plug connector composition. Cover plate and base plate surround an electric-controlled box housing, line jointlyRoad plate is arranged on base plate, and is positioned at electric-controlled box housing. Plug connector is arranged in cover sidewall, insertsThe equal vertically-arranged of fitting, the square casing that whole electric-controlled box housing is standard.
The subject matter that this structure exists is: because the size of plug connector differs, motor power is pegged graftThe size of part is all higher than sensor signal plug connector, vehicle body electric power connecting and vehicle body signal plug connector, and coversPlate, in order to meet the installation requirement of motor power plug connector, also will correspondingly increase height and this plug connectorCoupling, thus make whole electric-controlled box seem huge, bring a lot of troubles to mounting arrangements, especially at skyBetween in limited situation, cannot install at all. Meanwhile, each plug connector arranges separately, and main engine plants are carrying outWhen general assembly, often can produce between line and disturb, affect efficiency of assembling.
Summary of the invention
The present invention is directed to above-mentioned technical problem and improve, intend providing a kind of compact conformation, small volumePower-assisted steering electric-controlled box, and disturb between line can effectively stop general assembly time.
For this reason, the technical solution adopted in the present invention is: a kind of power-assisted steering electric-controlled box, comprise wiring board,Rectangular base plate and the cover plate mating with rectangular base plate, be provided with to downward along the circumferential edge of described cover plateThe sidewall of stretching, surrounds an electric-controlled box housing jointly with base plate, and described wiring board is arranged on base plate, andBe positioned at electric-controlled box housing, be respectively arranged with installation journal stirrup at the left and right side of described base plate, in cover plate sideMotor power plug connector, sensor signal plug connector, vehicle body power supply plug-in unit and vehicle body signal are housed on wallPlug connector, is characterized in that: described motor power plug connector becomes with sensor signal plug connector integrated injection moldingType, is arranged on the front side wall of cover plate; Vehicle body power supply plug-in unit becomes with vehicle body signal plug connector integrated injection moldingType, is arranged on the rear wall of cover plate; Described motor power plug connector is horizontal, sensor signal plug connector,Vehicle body power supply plug-in unit and vehicle body signal plug connector vertically-arranged; Described cover plate from middle part to anterior height graduallyReduce, the height from middle part to rear portion remains unchanged; Taking separated time in the left and right of described electric-controlled box housing as boundary,Motor power plug connector and vehicle body power supply plug-in unit are positioned at left side, and sensor signal plug connector and vehicle body letterNumber plug connector is positioned at right side; The left side wall part of described base plate stretches out and forms interval, two front and back layoutCircular mounting journal stirrup, the right side wall part of base plate stretch out form a circular mounting journal stirrup, threeCircular mounting journal stirrup triangularity is arranged, and the height of installation journal stirrup is greater than the thickness of base plate; Described cover plateThe part, lower end of left and right sidewall extends to form positioning convex downwards, on the left and right sidewall of described base plate, establishesBe equipped with and the detent that positioning convex quantity equates, position is corresponding, size is mated, described positioning convexStretch into the installation location of realizing base plate and cover plate in detent.
The postmedian at described cover plate top is provided with the punching press reinforcement of rectangular ring. At the flat part of cover plateDivide punching press reinforcement, both improved the intensity of whole housing, reduced again mould complexity.
Beneficial effect of the present invention:
(1) every two plug connector integrated injection moldings, arranged apart on forward and backward sidewall, optimized fourThe layout of individual plug connector, has simplified number of molds, has reduced assembling complexity, has saved manufacturing cost,Compact conformation, and avoided disturbing between the line of each plug connector;
(2) by horizontal highly maximum motor power plug connector, and highly general sensor signal is insertedFitting, vehicle body power supply plug-in unit and vehicle body signal plug connector continue to adopt existing vertically-arranged mode, will simultaneouslyCover plate reduces near one end height of motor power plug connector, to vacate the space at the front top of cover plate, justIn the reasonable Arrangement of whole assembly, avoid producing and interfere;
(3) taking separated time in the left and right of electric-controlled box housing as boundary, two power supply plug-in units (being forceful electric power) homonymyArrange, two signal plug connectors (being light current) homonymy layout, strong, weak electricity is respectively a word line to be arranged,Facilitate assembly to arrange, correspondingly, in the circuit board strong, weak electricity is separated, avoid electromagnetic interference, improveThe reliability of product;
(4) three circular mounting journal stirrups form the mounting points of power-assisted steering electric controller, and the height of journal stirrup is installedDegree is greater than the thickness of base plate, ensures to install the intensity of journal stirrup;
(5) installation of base plate and cover plate, by positioning convex and detent location, can realize quick locationInstall.
