Description
Technical field
The invention belongs to automobile electrically-controlled technical field, is related to a kind of automobile-used electric-controlled box, more particularly, to a kind of water proof and dust proof
Electric-controlled box radiator structure.
Background technology
Existing automobile central control box body solely considers the sealing of box body or the thermal diffusivity of product, does not examine simultaneously
The sealing and thermal diffusivity of product are considered, because sealing and thermal diffusivity have counter performance.Plain edition electric-controlled box sets sealing general
It is that electric-controlled box lid is sealed using caulking gum packing ring, next to that being carried out using encapsulating mode to electric-controlled box port position
Sealant pouring and sealing；Both mode sealing effectiveness are all relatively better, but the process produced is cumbersome, product cost is higher, and dissipate
Hot property is poor.Sealing and thermal diffusivity exist it is converse, when running counter to relation, i.e. good airproof performance, thermal diffusivity is relatively poor；Thermal diffusivity
When good, sealing is relatively poor.For most of automobile-used electric-controlled boxes, sealing and radiating is set all to reach ideal effect
Fruit, it is that those skilled in the art are often required to one of technical barrier for facing.The hair of my company's Application No. 201110301506.2
Bright patent discloses a kind of control box body of automobile central electric appliance, has both considered the sealing of control box body, has taken into account control box again
Heat dispersion, sealing, dust-proof, good water-proof effect.But found in use, its radiating effect does not include ideal, is on the one hand convex
Gap between platform medial surface and groove side wall is vertical masonry joint, and hot gas, which is flowed at gap, to be not easy to discharge；On the other hand it is steam vent
Fraction blocked by sealing ring, hinder thermal current from steam vent discharge.
The content of the invention
It is simultaneous so as to reach the invention provides a kind of electric-controlled box radiator structure of water proof and dust proof in order to solve the above problems
Care for its sealing and the effect of thermal diffusivity.
The present invention is achieved by following technical solution.
A kind of electric-controlled box radiator structure of water proof and dust proof, including lid and cassette bottom, the lid coordinate with cassette bottom, the box
Cover buckle is covered in cassette bottom, and the face that the lid coordinates with cassette bottom is provided with boss, corresponding, is set in the mating surface of the cassette bottom
There is seal groove, the sealing trench bottom is provided with steam vent, and the boss section is equal between inverted trapezoidal, and three faces of seal groove
Gap is left, sealing ring is provided between boss top surface and sealing groove bottom, is provided with the inside of the sealing ring with steam vent one by one
Corresponding exhaust groove, is provided with groove on the cassette bottom top surface, and heat emission hole is surrounded between mating surface under groove and lid, described to dissipate
Hot hole connects with exhaust groove and steam vent.
Further, the sealing ring is pressed close on the outside of seal groove and installed.
Further, the steam vent is located on the inside of seal groove, and is circumferentially uniformly distributed along seal groove.
Further, the heat emission hole is uniformly distributed along cassette bottom upper surface, indention arrangement.
Further, the sealing ring is the rubber seal of square-section.
Further, the inner side of the trapezoid cross section of the boss tilts or two sides tilt.
The beneficial effects of the invention are as follows：
A kind of electric-controlled box radiator structure of water proof and dust proof of the present invention, is covered in cassette bottom by lid button, and box body
The effect for closely, having reached waterproof and dustproof is bonded with lid；By setting heat emission hole on the inside of cassette bottom, the heat emission hole port of export is opposite
Inclined plane, there is guide effect to heat, reduce and atmidometer, thermal current is easier from heat emission hole out；Inside control box
Thermal current can be by heat emission hole, the gap between boss and cassette bottom seal groove inwall through lid enters in seal groove, then
It is discharged to by the sealing ring exhaust groove and steam vent that seal trench bottom outside box body, more preferable radiating effect can be reached；This structure
The sealing property and heat dispersion of control box body have been taken into account simultaneously, and it is dust-proof, anti-both to have considered automobile control box working environment needs
The characteristics of water, it is also considered that its in the case of hot environment and overload caused high temperature to control box inner member and box body meeting
Certain infringement is produced, improves the heat-sinking capability of box body and dust-proof, water resistance, so as to improve the reliability of product, and can
Extend its service life.

Embodiment
Technical scheme is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in Fig. 1~5, a kind of electric-controlled box radiator structure of water proof and dust proof of the present invention, including lid 1 and cassette bottom
3, the lid 1 coordinates with cassette bottom 3, is connected by screw fastening, and the button of lid 1 is covered in cassette bottom 3, to prevent water drop to be directly entered
Matching part, the face that the lid 1 coordinates with cassette bottom 3 are provided with boss 2, and corresponding, the mating surface of the cassette bottom 3 is provided with
Seal groove 5, the bottom of seal groove 5 are provided with steam vent 7, and the steam vent 7 is located at the inner side of seal groove 5, and circumferential along seal groove 5
It is uniformly distributed；The section of boss 2 is inverted trapezoidal, and the inner side of the trapezoid cross section of boss 2 tilts or two sides tilt, convex
Gap is left between platform 2 and three faces of seal groove 5, sealing ring 4, institute are provided between the top surface of boss 2 and the bottom surface of seal groove 5
State sealing ring 4 and press close to the outside of seal groove 5 and install, sealing ring 4 is the rubber seal of square-section, the inner side of sealing ring 4 be provided with
The one-to-one exhaust groove 8 of steam vent 7, the boss 2 play pressuring action to sealing ring 4；The top surface of cassette bottom 3 is provided with
Heat emission hole 6 is surrounded between groove, with 1 time mating surface of lid, the heat emission hole 6 connects with exhaust groove 8 and steam vent 7.
The heat emission hole 6 is uniformly distributed along the upper surface of cassette bottom 3, indention arrangement, and heat is carried out by heat emission hole 6 in box
Radiating, so as to reduce temperature in box, preventing in box that temperature is too high makes product plastic deformation, influences product quality.
Embodiment
When lid 1 and cassette bottom 3 are fitted close, due to working environment or load effect inside control box, make inside it
Temperature is raised, and now, as shown in Figure 6, Figure 7, tray interior heat is entered in the medial surface of boss 2 and seal groove 5 by heat emission hole 6
Gap between wall, under the guiding of the medial surface inclined plane of boss 2, then exhaust groove 8 and steam vent by the bottom of seal groove 5
7, it is discharged to outside control box box body, makes interiors of products heat be easier to discharge, more efficiently have adjusted product internal temperature, play
It good radiating effect, ensure that interiors of products component radiates in time, so as to ensure that product quality, improve product use
Life-span；After box body is completed, because steam vent 7 is located at the lower section concealment part at the edge of cassette bottom 3, box body contacts with water and dust
All it is not easy to enter in box body at steam vent 7, so as to reach good waterproof and dustproof effect.
According to hung to vehicle electric-controlled box, dust-proof, classification of waterproof requires higher during to outdoor study, and box body temperature sink
The characteristics of very fast, this structure are also applied on the heavy-duty machineries such as large-scale truck, engineering machinery；As the technical program is in work
