Abstract
The utility model provides a sealing structure of an electric vehicle controller. The sealing structure of the electric vehicle controller comprises an upper cover and a lower cover which are clamped with each other. Control assemblies are disposed in a cavity formed between and enclosed by the upper cover and the lower cover. Additionally, a sealing ring is arranged between the upper cover and the lower cover to prevent water from penetrating into the cavity. A protrusive strip is disposed on an end portion of the upper cover. A groove is disposed in the upper bottom face of the lower cover. The protrusive strip of the upper cover and the groove of the lower cover are mutually clamped. The sealing ring additionally arranged between the upper cover and the lower cover is embedded into the groove in the upper cover or the lower cover, can effectively prevent dust or water from penetrating into the inside from the outside, and plays a role of sealing and protecting the control assemblies in the cavity. Meanwhile, a connecting surface between the upper cover and the lower cover is moved into the inside from the outside, and thus the penetration by the dust can be substantially reduced.
Description
Technical field
The utility model relates to electric automobile, refers to especially a kind of hermetically-sealed construction of electric vehicle controller.
Background technology
Along with the enhancing gradually of environmental consciousness, nowadays fuel orthodox car is replaced by novel electric vehicle gradually.In existing electric automobile, the controller of electric automobile is a square casing, be built-in with various control assemblys, in controller, lock in outside by screw, contact-making surface is in the outside of controller, dust or the water capacity are easily therefrom infiltrated in controller cavity, and various control assemblys are caused corrosion or polluted, and affect its service behaviour and precision.
Utility model content
Based on the deficiencies in the prior art, main purpose of the present utility model is to provide the hermetically-sealed construction of the electric vehicle controller with sealing ring, by set up sealing ring between upper cover and lower cover, plays the effect of dustproof and waterproof vibration damping.
The utility model provides a kind of hermetically-sealed construction of electric vehicle controller, it comprises upper cover and the lower cover of mutual fastening, built-in each control assembly in the cavity encapsulating between upper cover and lower cover, wherein, between described upper cover and lower cover, have additional sealing ring, prevent that infiltration from entering in cavity.
Preferably, the end of described upper cover is provided with raised line, and the upper bottom surface of lower cover offers groove, and the raised line of described upper cover and the groove of lower cover fasten mutually.Certainly, the position of raised line and groove can also be replaced, and the end of described upper cover is provided with groove, and the upper bottom surface of lower cover is provided with raised line, and the raised line of described lower cover and the groove of upper cover fasten mutually.Described raised line and groove are around the outer rim setting of upper cover or lower cover.By the mutual fastening of raised line and groove, so that upper cover and lower cover are assembled into one.
Preferably, the side of described sealing ring is curved, to avoid water to infiltrate in cavity from outside.Meanwhile, sealing ring is made as arcwall face, and point between sealing ring and groove inwall is contacted, and has reduced both frictions.
Compared with prior art; the hermetically-sealed construction of a kind of electric vehicle controller of the utility model; between upper cover and lower cover, have additional sealing ring; sealing ring is embedded in the groove of upper cover or lower cover; can effectively prevent that dust or water from infiltrating from outside inner, the control assembly in cavity is played to seal protection effect.Meanwhile, the joint face between upper cover and lower cover is moved into inside from outside, can greatly reduce dust and infiltrate.The side of sealing ring is arc, contacts with the inwall point of groove, has reduced the friction stree of both contacts.

Fig. 3 is the structure chart of the lower cover of the hermetically-sealed construction of a kind of electric vehicle controller of the utility model;
Fig. 4 is the enlarged drawing in A district of the hermetically-sealed construction of a kind of electric vehicle controller of the utility model.
Embodiment
Shown in Fig. 4, the utility model provides a kind of hermetically-sealed construction of electric vehicle controller, it comprises upper cover 1 and the lower cover 2 of mutual fastening, built-in each control assembly in the cavity 3 of encapsulation between upper cover 1 and lower cover 2, wherein, between described upper cover 1 and lower cover 2, have additional sealing ring 4, prevent that infiltration from entering in cavity 3.
Described upper cover 1 is a square cover body, wherein has a cavity 3, can be built-in various for driving the control assembly of electric automobile operation in cavity 3.Described lower cover 2 is the tetragonal body structure matching with the shape of upper cover 1, and four jiaos of lower cover 2 have screw hole, after by upper cover 1 and the mutual fastening of lower cover 2, penetrates the screw hole of lower cover 2 by screw from upper cover 1, and upper cover 1 and lower cover 2 are locked mutually.
In an embodiment of the present utility model, the end of described upper cover 1 is provided with raised line 10, and the upper bottom surface of lower cover 2 offers groove 20, and the raised line 10 of described upper cover 1 and the groove 20 of lower cover 2 fasten mutually.Described raised line 10 extends along the outward flange of upper cover 1, forms annular raised line 10.Accordingly, the groove 20 of described lower cover 2 also extends along the outward flange of lower cover 2, ringwise groove 20, and position and the corresponding coupling of profile of the position of groove 20 and raised line 10, can fasten both mutually.Described sealing ring 4 is clipped between raised line 10 and groove 20, can infiltrate in cavity 3 from outside by anti-sealing by sealing ring 4,, make because sealing ring 4 adopts rubber elastomeric material meanwhile, be embedded between upper cover 1 and lower cover 2, also can alleviate the vibration between upper cover 1 and lower cover 2.The side of described sealing ring 4 is curved, and point between sealing ring 4 and groove 20 inwalls is contacted, and has reduced both frictions.
In another embodiment of the present utility model, the position of described raised line 10 and groove 20 can also be replaced, and described raised line is arranged on lower cover 2, and described groove is opened on upper cover 1, and the raised line of described lower cover and the groove of upper cover fasten mutually.
The hermetically-sealed construction of a kind of electric vehicle controller of the utility model; between upper cover and lower cover, have additional sealing ring; sealing ring is embedded in the groove of upper cover or lower cover; can effectively prevent that dust or water from infiltrating from outside inner; control assembly in cavity is played to seal protection effect; the side of sealing ring is arc, contacts with the inwall point of groove, has reduced the friction stree of both contacts.
