Abstract
The invention discloses a connecting device for an expansion brake block of an electrombile. The connecting device comprises a bracket, a cover plate, a first lug, a second lug and a hole, wherein a lug pair is arranged on the outer edge of the bracket and consists of the first lug and the second lug, the cover plate closely clings to the outer edge of the bracket, the hole is arranged on the cover plate and is matched with the first lug and the second lug in position and shape, the parts of the first lug and the second lug, extending out of the cover plate, are of elbow structures, the elbows closely cling to the cover plate, and the cover plate and the bracket are fixed together to form a whole. According to the invention, the adhesive force of the cover plate with the friction material of the bracket is greatly improved, so that the structure is firmer and in no need of welding, thereby saving cost.
Description
Technical field
The present invention relates to a kind of battery-driven car parts, be specifically related to a kind of electric vehicle expansion lock slipper connecting device.
Background technology
The present bicycle in the society, the battery-driven car major part all need be used the good lock that rises of deceleration and stopping performance, and like Fig. 1, shown in Figure 2: the lock inboard of rising is furnished with two shoe brake pieces; Brake shoe is made up of support 1 and cover plate 2, is pressed with the blob of viscose of friction material on the cover plate 2, and support is provided with projection 3, cover plate 2 has hole 4; Projection 3 is complementary with hole 4; Solder joint piece 5 is set near projection 3, through fixedly spot welding of welding machine, after weld; Because during spot welding; Size of current, weld time are difficult to grasp, and the mechanical property of materials is damaged and causes recessive separation-type fracture, thereby the situation generation that after the position in support 1, projection 3, cover plate 2, hole 4 replenishes welding, still has support and cover plate fracture to separate again.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, a kind of electric vehicle expansion lock slipper connecting device is provided.
The technical scheme that the present invention adopts is: a kind of electric vehicle expansion lock slipper connecting device; Comprise support, cover plate, first projection, second projection and hole, it is right that the outer rim of said support is provided with projection, and projection is to being made up of first projection and second projection; Said cover plate is close to the outer rim of support; Cover plate is provided with the hole, and the position in hole and shape and first projection, second projection are complementary, and the part that first projection, second projection stretch out cover plate is the elbow structure; And elbow is close to cover plate, and cover plate and support are fixed into an integral body.
As preferably, the elbow on said first projection and second projection is a different directions.
As preferably, according to the brake shoe size of the lock that rises, it is how right to projection to be provided with on the outer rim of said support.
As preferably, be provided with recess around the said hole, the elbow on the position of recess and shape and first projection, second projection is complementary, and makes the projection on the support be arranged at the thickness that the cover plate recess does not influence friction shoe on the cover plate.
Beneficial effect: the present invention has strengthened the binding power of cover plate and support friction material greatly, makes structure not only more firm, and need not weld, and saves cost.
