Detailed description of the invention

As shown in Figure 3, Figure 4, the carriage interface of an embodiment of the present utility model, for the housing of Body control module, comprise interface body 1 and be arranged at the holding part 3 of interface body 1 both sides, carriage interface also comprises: interface body is provided with the projection 5 with interference surface 51, and interference surface 51 is interfered for being formed with the edge 611 of through hole 61 of the support 6 inserting carriage interface.

Protruding 5 is trapezium structure, two waists of trapezium structure are interference surface 51, support 6 inserts carriage interface, under the pressure effect of holding part 3, the end of protruding 5 is embedded in the through hole 61 of support 6, the edge 611 of through hole 61 is stuck in interference surface 51 and forms interference, thus forms zero-lash between protruding 5 and support 6 closely cooperating, as shown in Figure 4.

Owing to being zero-lash closely cooperating, can avoid producing in vehicle travel process the wearing and tearing that noise and phase mutual friction cause.

The end of protruding 5 can embed in the through hole 61 of support 6, and the bottom of protruding 5 can not embed in the through hole 61 of support 6.

Two parts are projection 5 and support 6, the mating surfaces of the two is the upper limb of the through hole 61 of interference surface 51 and support 6, location overlap on the contact surface, produce elastic deformation, the relative sliding of the mechanical resistance produced by elastic deformation only between protruding 5 and support 6, formation protruding 5 closely cooperates with support 6.

In the present embodiment, protruding 5 comprise two interference surface be oppositely arranged 51, and making protruding 5 can the movement of limit bracket 6 upwards, downwards in both direction, therefore, it is possible to two-way installation.And buckle 4 of the prior art, as shown in Figure 1, only there is a locking face, can only limit bracket 6 move up, therefore can only install from the top down, can not two-wayly install.

The interference surface 51 of the present embodiment protrusions 5 comprises a sub-interference surface, and this sub-interference surface is plane, as shown in Figure 5 a.

In another embodiment, the interference surface 51 of protruding 5 comprises two sub-interference surfaces, the angle 5121 of the first sub-interference surface 511 and the sub-interference surface 512 of the second sub-interference surface 512, second and interface body 1, be greater than the angle 5111 of the first sub-interference surface 511 and interface body 1, as shown in Figure 5 b.

Second sub-interference surface 512 equals 90 degree with the angle 5121 of interface body 1 is maximum, as shown in Figure 5 c.

Interference surface comprises the first sub-interference surface 511 and the second sub-interference surface 512 that different angles are arranged, and after installation, edge 611 and the plane 511 of the through hole 61 of usual support 6 are formed interferes.In vehicle travel process, if device is impacted, make edge 611 depart from plane 511, edge 611 can be formed with plane 512 interferes, and stops support 6 to be deviate from from carriage interface.

In another embodiment, interference surface 51 also can comprise multiple sub-interference surface, such as three, the sub-interference surface of the end near protruding 5 and the angle of interface body 1 maximum.

In another embodiment, sub-interference surface also can be curved surface, and such as protruding 5 is taper platform, and each interference surface comprises a sub-interference surface, and sub-interference surface is part conic face.

In the present embodiment, carriage interface injection moulding together with the housing of Body control module is formed, support is metallic support, and the edge of the through hole on metallic support can be formed with the interference surface of plastics interferes, thus forms plastic stent interface and metallic support is zero-lash closely cooperates.

In the utility model, the material forming two parts (carriage interface and support) of interfering is not limited, both can be made by the material of identical type or same rigidity, also can be made by the material of variety classes or different hardness.Such as carriage interface and support all can adopt plastic production, also can all adopt metal to make, and all right one adopts plastic production, and one adopts metal to make.

Carriage interface of the prior art, for the thickness bad adaptability of support 6, thinner support 6, the gap between support 6 and carriage interface is comparatively large, easily produces noise, also easily weares and teares; Thicker support 6, possibly cannot insert carriage interface.

As shown in Figure 6, holding part 3 comprises press keeping section 31 and elastic portion 32, and press keeping section 31 is for being pressed in carriage interface by support 6, and the cylinder of elastic portion 32 to be cross-sectional planes be arc, for regulating the spacing between press keeping section 31 and rack body 1.When inserting the support 6 of different-thickness, because the elastic portion of arc has flexibility, press keeping section 31 can both contact well with support 6, firm grip support 6, can adapt to the support of different-thickness.

In addition, the cross-sectional plane of elastic portion also can be the structure of the similar arc be made up of polygon.

As shown in Figure 3, inside the one or both ends of holding part 3, be provided with guiding surface 33, make support 6 insert carriage interface easier.

Carriage interface also comprises the stay bearing plate 2 be arranged in interface body 1, adopts stay bearing plate 2 can reduce the working accuracy of the spacing between holding part 3 and rack body 1, is convenient to support 6 and inserts carriage interface.

A housing for electronics package, the housing of such as Body control module, as shown in Figure 7, the multiple above-mentioned carriage interface of arranged outside, inserts support from below or inserts support from top, Body control module can both be securely fixed in vehicle.

Although the utility model discloses as above with preferred embodiment, the utility model is not defined in this.Any those skilled in the art, not departing from the various change and amendment done in spirit and scope of the present utility model, all should include in protection domain of the present utility model, therefore protection domain of the present utility model should be as the criterion with claim limited range.
