Description

A cushion support assembly suitable for passenger car back doors

technical field

The invention belongs to the field of automobile body manufacture, and in particular relates to a cushion support assembly of an automobile back door accessory system.

Background technique

With the continuous development of society, consumers have a deeper and deeper understanding of cars, and they have higher and higher requirements for the comfort and man-machine of current cars. The back door is one of the main components of the hatchback body parts. Consumers not only require that the back door should not make abnormal noise or scratch other matching parts due to the vibration of the bumpy road during the driving process of the car; they also require the appearance of the back door Give people a visual enjoyment. The car back door often solves the problem of abnormal noise or scratches on the back door due to the vibration of the bumpy road by installing a cushion on the back door body. Due to the limitations of the size of the cushion and the structure of the car body, Its mating surface cannot be in smooth contact with the car body, so that the expected effect of the cushion pad cannot be achieved, and the shape of the whole car is often sacrificed to avoid the problems of abnormal noise and scratching other parts. As shown in Figure 1, when the height of the mating surface of the cushion pad 1 and the car body 4 is too large for the traditional car back door 2 to be in contact with the car body smoothly to achieve cushioning and shock absorption, it is often achieved by increasing the height of the boss 3 on the car body. The buffer pad 1 is in contact with the vehicle body 4 to achieve the effect of buffering and shock absorption, but this will not only make the processing of the vehicle body more difficult, but also the shape of the entire vehicle body will be greatly compromised because of the defect.

Contents of the invention

In order to solve the defect that the buffer pad cannot be well matched with the vehicle body, the invention provides an automobile buffer pad support assembly with simple processing, convenient installation, good cooperation with the buffer pad and exquisite appearance.

Technical scheme of the present invention is as follows:

A cushion support assembly suitable for the back door of a passenger car. The assembly has a drum-shaped structure and includes a cushion support and a support waterproof pad. The lower part of the cushion support is pasted and connected to the support waterproof pad. The center of the buffer pad support assembly has a through bolt hole, and the top of the bolt hole is a counterbore structure, and the depth of the counterbore hole is consistent with the thickness of the pan head of the bolt. flush with the top surface of the bolt's pan head.

Further, the lower part of the bolt hole is expanded into an avoidance hole whose diameter is larger than that of the bolt hole.

Furthermore, the support of the cushion pad is made of PC plus ABS material, and the waterproof pad of the support is made of closed-cell foamed EPDM material.

When the cushion support assembly of the present invention is installed, there is a counterbore at the top of the bolt hole at the center of which is matched with the bolt. The top of the head is even, so that the mating surface of the cushion pad is increased, and the contact surface between the cushion pad and the cushion support assembly is not reduced due to the height difference between the cushion support assembly and the matching cross-recessed countersunk head screw, so that the cushion The pad achieves the function of cushioning during use; and due to the use of the cushion support assembly, the size of the boss on the surface of the car body and the cushion pad is small, which is not only beneficial to the processing of the car body structure, but also conducive to the maintenance of the car body. beautiful.

detailed description

Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

As shown in Figures 2, 3 and 4, the cushion support assembly has a drum-shaped structure 8, including a cushion support 6 and a support waterproof pad 7, and the lower part of the cushion support is pasted and connected with the support waterproof pad. The center of the buffer pad support assembly has a through bolt hole 9, and the top of the bolt hole is a counterbore structure, and the depth of the counterbore hole is consistent with the thickness of the pan head of the bolt. The surface is flush with the top of the bolt's pan head.

The lower part of the buffer pad support is expanded into an avoidance hole 10 whose diameter is greater than that of the bolt hole. The support of the buffer pad can be made of PC+ABS material, and the waterproof pad of the support can be made of closed-cell foamed EPDM material.

In order to ensure the airtightness of the fit, the size of the bolt hole 9 should be slightly smaller than the size of the bolt 11, and an interference fit is used.

As shown in Figure 5, when the cushion support assembly of the present invention is fixed on the vehicle body, its top is matched with the cushion pad 1; Interference; the avoidance hole 10 with a large bottom size is used to keep the part in contact with the car body 4 as small as possible without affecting the assembly, so as to avoid the contact with the bump 12 of the car body as much as possible to affect the buffering The waterproofness of the cushion support assembly; the closed-cell foam support waterproof cushion 7 is pasted on the lower part of the cushion support 6, which can better prevent water from entering the mating surface of the cushion support assembly and the vehicle body 4 affect the life of parts.
