Description

A New Type of Passenger Car Cabin Door Heat Dissipation Structure

technical field

The invention relates to a heat dissipation structure for passenger car cabin doors, which is mainly used on passenger car side and rear wall hatches. Through this structure, the grille is opened by means of the wind force discharged by the cooling fan in the cabin to realize efficient heat dissipation. When the cooling fan stops When working, the grille can be closed automatically due to the design of the upper eccentric hole and the limit device.

Background technique

The heat dissipation hatch of a passenger car is an important exterior decoration and covering part on the passenger car body. It should not only have a simple and beautiful appearance and a reliable structure, but also meet various requirements for use. With more and more differentiated configurations of passenger cars, configurations such as ATS fan engine cooling and rear-mounted passenger car air conditioners continue to appear and are widely used in conventional passenger cars. These parts are often designed with large cooling fans to meet the use requirements. There is a need for efficient heat dissipation for the relevant heat dissipation hatches. The ventilation rate of the traditional hatch heat dissipation structure is often lower than 60% of the opening area of the hatch skin, which cannot meet the heat dissipation requirements. Therefore, a new hatch heat dissipation structure is needed to solve the current problem.

Contents of the invention

In order to solve the above-mentioned problems, the present invention designs a brand-new heat dissipation structure for the cabin door of passenger cars, and the ventilation rate of the cabin door can be increased to more than 80% through the rotating blade grille.

The blade rotation mechanism includes a nylon pin with holes, a stainless steel shaft, a lateral limit block, and a maintenance-free plastic bushing;

The slotted side frame of the hatch door is bonded with a nylon pin fixing part with holes; the stainless steel rotating shaft is inserted into the nylon pin fixing part with holes on one side, and the transverse limit pad is installed on the rotating shaft;

The holes at both ends of the perforated blade grid are fitted on the stainless steel rotating shaft through maintenance-free plastic bushings.

The diameter of the stainless steel rotating shaft is 5mm; the stainless steel rotating shaft is interference fit with the nylon pin shaft fixing part with holes.

The sponge strip is pasted in the concave groove at the lower part of the perforated blade grid.

The perforated blade grid can rotate around the center of the rotating shaft under the wind force of the cooling fan in the cabin; the perforated blade grid is designed with a limited structure, and the upper end of the blade is outwardly inclined and the lower end is inwardly inclined due to the center of gravity in the natural state. As a result, two adjacent grids are connected to form a natural closure, which is kept perpendicular to the ground plane.

The lower part of the perforated blade grid is designed with a curved and folded shape.

The installation steps of the cooling structure are as follows:

Open a square hole on the outer skin of the hatch, bend and flang the upper and lower sides of the square hole, and design a frame-shaped skeleton on the inner side of the skin, including the slotted side skeleton of the hatch and the transverse skeleton of the hatch to form a heat dissipation cabin The basic frame of the door;

Bond the nylon pin fixing piece with holes in the groove of the slotted side frame of the hatch, and at the same time insert a 5mm diameter stainless steel shaft into the nylon pin fixing piece with holes on one side, and install the lateral limit pad on the shaft superior;

Put the maintenance-free plastic bushing into the holes at both ends of the perforated blade grille; insert another stainless steel shaft into the hole at the other end of the grille, and then pass the other end of the grille together with the bushing and fix it on the hatch on the stainless steel shaft;
