Specific embodiment

Such as Fig. 1, shown in 2,3, a kind of motor-car switching mechanism glass reinforced plastic outer cover with centering body, including it is left head-shield 1, right Head-shield 2 and fixed cover 3, design specialized mold, left head-shield molds molding mode using vacuum with right head-shield, fixed to be provide with meter specially Mold and tooling guarantee appearance and modeling and install the accuracy of interface；The left head-shield 1 and 2 corresponding part of right head-shield are set There is arc-shaped protrusion 7, centering body 4 is equipped between the left head-shield and right head-shield and centering body (4) is set to left head-shield and the right side In the protrusion 7 of head-shield, the centering body includes the centering concave head 5 on the left head-shield and the centering plush copper 6 set on right head-shield, Centering body uses adhesive tool, to guarantee the position of installation.

Such as Fig. 4, shown in 5, the centering concave head 5 is the bolt arrangement that there is a circular groove 51 at top center, described right Perforative through-hole 52 is equipped with inside middle concave head 5.

From figure 3, it can be seen that the centering concave head 5 is fixed on left head-shield 1 by hex nut 53.The hexagonal spiral shell Spring washer 54 and plain washer 55 are equipped between mother 53 and left head-shield 1.

Such as Fig. 6, shown in 7, the centering plush copper 6 is disc structure, and it is convex that the center of the centering plush copper (6) is equipped with arc-shaped It plays 61 and arc-shaped protrusion 61 and the circular groove 51 of centering concave head matches.

61 outside of arc-shaped protrusion of the centering plush copper is equipped with mounting hole 62, and the mounting hole 62 can be incited somebody to action by bolt 63 Centering plush copper 6 is fixed with right head-shield 2.

The quantity of the mounting hole 62 is 4.

As shown in figure 8, being respectively equipped with reinforced metal part 8, the reinforced metal part on the inside of the left head-shield 1 and right head-shield 2 Including metal body 81 and reinforcing rib 82, the metal body 81 is centered concave head 5 respectively and centering plush copper 6 passes through and tightly Keep left head-shield and right head-shield, and the reinforcing rib 82 is vertical with metal body 81 and is close to according to the shape of left head-shield and right head-shield In on left head-shield and right head-shield.

Centering body is devised between the head-shield of left and right, avoids and covers in practical entrucking that interference, face occur poor outside glass reinforced plastic The problems such as, there is complete installation interface in an installation, can be very easily adjusted after entrucking, do not need because of entrucking error Nonstandard change is carried out to product, the working hour of entrucking can be effectively reduced, improves entrucking efficiency；The excellent appearance and modeling energy of the present invention Air drag is enough reduced, motor-car energy consumption is reduced.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
