Description

Roof structure, manufacturing method and vehicle

technical field

The present disclosure relates to the technical field of vehicles, and in particular, to a vehicle roof structure, a manufacturing method and a vehicle.

Background technique

The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art.

At present, the traditional way of connecting the car roof and the side wall is to first weld them together by electric welding, then apply electric welding sealant, and finally leave a large gap. In order to solve the problem of water leakage, a sealing strip is also attached to seal it. Then, the gap left by the electric welding is filled with expansion glue, and further waterproofing is completed.

The inventors of the present disclosure have found that with such a traditional roof structure, as the vehicle is used for an extended period of time, the roof is prone to loosening, and a roaring sound may occur inside the vehicle; There is twist on both sides of the top cover, and the top cover is prone to abnormal noise, which reduces the strength of the top cover.

SUMMARY OF THE INVENTION

In order to solve the deficiencies of the prior art, the present disclosure provides a roof structure, a manufacturing method and a vehicle. By changing the modeling structure of the roof, combining the bonding of the upper and lower layers and the height difference, the water leakage prevention function is ensured, It essentially solves the problem of water leakage, while also saving costs and improving production efficiency.

In order to achieve the above object, the present disclosure adopts the following technical solutions:

A first aspect of the present disclosure provides a vehicle roof structure.

A vehicle roof structure includes a top cover, an upper enclosure cover plate and an upper vehicle body assembly, the upper side of the upper enclosure cover plate is provided with a groove, the groove divides the upper enclosure cover plate into two parts, and the groove One side of the groove is the main body of the upper enclosure cover, and the other side of the groove is the protrusion of the upper enclosure cover;

The front edge of the top cover is bent downward and extends into the groove, and the position of the bottom surface of the top cover close to the front edge is closely fitted with the upper surface of the protruding portion of the upper enclosure cover;

The upper body assembly includes a first protruding portion extending upward, and the outer surface of the first protruding portion is in close contact with the lower surface and the end surface of the protruding portion of the upper cowl cover and the bottom surface of the upper cowl cover.

A second aspect of the present disclosure provides a manufacturing method for the vehicle roof structure described in the first aspect of the present disclosure. First, a vehicle body assembly is installed, and then glue is applied to connect the upper cowling cover to the first protruding portion. Fix and glue, and finally fix the top cover on the upper side of the upper wall cover by gluing.

A third aspect of the present disclosure is a vehicle, including the roof structure described in the first aspect of the present disclosure.

Compared with the prior art, the beneficial effects of the present disclosure are:

1. The roof structure, method and vehicle described in the present disclosure ensure the water leakage prevention function by changing the modeling structure of the roof, combining the bonding of the upper and lower layers and the height difference, and essentially solves the problem of water leakage, At the same time, it saves costs and improves production efficiency.

2. In the roof structure, method and vehicle described in this disclosure, after installing the upper body assembly, first install the upper wall cover and then install the top cover, and fix the roof on the upper wall cover by applying glue twice Above, if it rains, the rainwater will accumulate in the grooves of the top cover and the upper cover plate, and because the grooves are located at a low position, the rainwater will flow out from the upper side after filling the grooves, and there will be no backflow. Happening.

3. With the roof structure, method and vehicle described in the present disclosure, even if rainwater is poured from the groove, it will only pass through two adhesive layers and then flow down from the outside of the upper body assembly, rather than from the top of the cab into the cab, avoiding the problem of rainwater leakage.

4. The roof structure, method and vehicle described in the present disclosure can be directly installed in place by applying glue at one time by means of bonding, which is convenient for installation, saves time and labor, and can play a role in the new design of flanging compared with the traditional structure. Better waterproof effect.

5. The roof structure, method and vehicle described in the present disclosure, through new structural coordination and two glue injection operations, omit other installation processes, such as sealant strips, electric welding sealants, etc. Repeated labor of sealant greatly saves manpower and material costs.
