Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

A ceiling assembly 100 according to an embodiment of the present invention, the ceiling assembly 100 being used in a vehicle, is described below with reference to fig. 1-4.

As shown in fig. 1 to 4, a ceiling assembly 100 according to an embodiment of the present invention may include: a ceiling 10 and a sealing structure 20, the sealing structure 20 being fixed to a rear edge of the ceiling 10, the sealing structure 20 being provided to protrude rearward at the rear edge of the ceiling 10, and a rear end of the sealing structure 20 being in contact with the back door 200. That is, the sealing structure 20 is provided at the rear edge of the ceiling 10, and the sealing structure 20 may have a long shape, and the length direction thereof may be the same as the width direction of the ceiling 10, i.e., the left and right direction shown in fig. 1, so that the sealing may be performed uniformly in a certain direction. This sealing structure 20 can be through the form and the back door 200 overlap joint cooperation that backward protrusion set up, and the rear end and the back door 200 of this sealing structure 20 contact, can effectively close the cavity between ceiling 10 and the back door 200 like this to can avoid wind to get into inside cavity, can avoid producing the cavity noise at the vehicle in-process of traveling, and then can promote user's use and experience.

In addition, by fixing the sealing structure 20 to the rear edge of the ceiling 10, the sealing structure 20 can be formed as an integral structure with the ceiling 10, a separate assembly step of the sealing structure 20 between the ceiling 10 and the back door 200 can be omitted, and the structural stability therein can be made higher.

Therefore, according to the utility model discloses ceiling assembly 100 through set up sealing structure 20 at the rear edge of ceiling 10, can effectively seal the cavity between ceiling 10 and back door 200 to can avoid producing the cavity noise, can guarantee sealing structure 20's reliability moreover, and then can rise user's use and experience.

According to an alternative embodiment of the invention, the length of the upper surface 21 of the sealing structure 20 is the same as the width of the ceiling 10. That is to say, the sealing structure 20 can extend from the left end to the right end on the rear edge of the ceiling 10, so that the sealing structure 20 can be arranged flush with the two ends of the rear edge of the ceiling 10, the connection reliability of the sealing structure 20 and the rear edge of the ceiling 10 can be improved, the sealing effectiveness can be ensured, and the problem of end air leakage can be avoided. Wherein the length of the upper surface 21 of the sealing structure 20 may be between 1100mm and 1200mm, for example 1100mm, 1125mm, 1150mm, 1175mm and 1200mm.

As shown in fig. 3, the width of the upper surface 21 of the sealing structure 20 is d1, and d1 satisfies the following relation: d1 is more than or equal to 6mm and less than or equal to 8mm. Wherein, cavity open-ended width can be 5.5mm, through the width of rationally setting up sealed structure 20 upper surface 21, can guarantee that sealed structure 20 covers the cavity opening completely and with back door 200 overlap joint cooperation, but also can leave certain interference volume to can avoid appearing the cavity noise. For example, d1 may be 6mm, 6.5mm, 7mm, 7.2mm, 7.5mm, and 8mm. The upper surface 21 of the sealing structure 20 may be disposed non-coplanar with the upper surface of the ceiling 10, for example, the upper surface 21 of the sealing structure 20 may be disposed to be inclined downward in a front-to-rear direction, which may facilitate guiding airflow and reduce wind resistance and noise.

Alternatively, the sealing structure 20 may be a rubber member vulcanized on the rear edge of the ceiling 10. The rubber member has a certain deformability, so that when the rubber member interferes with the back door 200, the rubber member can be kept sealed in a deformed manner, and the rubber member has a good sealing effect due to the self characteristic. In addition, since the rubber member is vulcanized on the rear edge of the ceiling 10, the connection reliability of the rubber member to the ceiling 10 is higher, the assembling step can be eliminated, and the assembling efficiency can be improved. Specifically, the rubber part is 65-70 Shore hardness. The rubber part has proper hardness, can better ensure the sealing effect and has higher reliability.

Wherein the front surface 22 of the rubber member is vulcanized to the rear edge of the ceiling 10 as shown in fig. 3, and the front surface 22 of the rubber member is an arcuate surface that is convex rearward. The provision of the arcuate surface can increase the vulcanization area of the rear edge of the ceiling 10, thereby further increasing the connection durability, improving the structural reliability of the ceiling assembly 100, and extending the service life of the ceiling assembly 100.

Further, as shown in fig. 3, the extension length from the upper end to the lower end of the arcuate surface is d2, and d2 satisfies the relation: d2 is more than or equal to 4.5mm and less than or equal to 6mm. That is, the distance from the upper end to the lower end of the arch surface is 4.5mm-6mm, that is, the width of the arch surface can be 4.5mm-6mm, so that the vulcanization area of the rubber member and the rear edge of the ceiling 10 can be further ensured, and the connection reliability of the rubber member and the ceiling can be ensured. For example, the distance that the arcuate faces extend from the upper end to the lower end may be 4.5mm, 4.8mm, 5.3mm, 5.7mm, and 6mm.

Alternatively, as shown in fig. 3, the sealing structure 20 has a triangular longitudinal section. Therefore, the sealing structure 20 can increase the sectional strength of the sealing structure 20 by using the characteristic of stable triangle, and the durability of the sealing structure 20 can be further improved. The longitudinal section is a section perpendicular to the left-right direction.

Further, as shown in fig. 3, the rear end of the sealing structure 20 is provided with a transition chamfer 24. Transition chamfer 24 department can take place to interfere with back door 200 when back door 200 opens and closes, and the setting of transition chamfer 24 can reduce the interference volume on the one hand, and on the other hand can be so that both relative motion smoothly when interfering, avoids back door 200 to block when opening and closing and feels.

The cavity noise can be effectively reduced by ensuring that the sealing structure 20 contacts with the back door 200, preferably, as shown in fig. 3 and 4, the lower surface of the rear end of the sealing structure 20 is in lap joint with the inner plate of the back door 200 in the closed state, the thickness of the sealing structure 20 at the position where the sealing structure is in lap joint with the inner plate of the back door 200 is d3, and d3 satisfies the relation: d3 is less than or equal to 1.5 mm. Wherein, the inner plate of the back door 200 is lapped with the lower surface of the rear end of the sealing structure 20, and the outer plate of the back door 200 is jointed with the rear end surface or the upper surface of the rear end of the sealing structure 20. The thickness d3 may be selected according to the actual situation, for example, d3 may be 1.5mm, 2.0mm, 2.5mm, 3.0mm, and the like. With the arrangement, a sufficient lap joint area can be effectively ensured between the sealing structural member 20 and the inner plate of the back door 200, and the sealing at the position can be better ensured, so that the problem of cavity noise can be avoided.

According to the utility model discloses vehicle, including the ceiling assembly 100 of above-mentioned embodiment. Adopt above-mentioned embodiment ceiling assembly 100's vehicle sealing performance good, can avoid producing the cavity noise, can promote user's use experience.
