Abstract
Description
Technical Field
[0001] The present application relates to the field of automobile technology, and in particular to a sunroof assembly and an automobile. Background Art
[0002] The sunroof assembly is installed on the roof of the car, usually including the sunroof glass, drainage groove and sealing strip. The drainage groove is wrapped around the outer edge of the sunroof glass. Due to the limitation of the drainage groove material (PP+GF30), the drainage groove cannot be directly overlapped with the car roof, and a gap needs to be left. The gap between the two is sealed by the sealing strip.
[0003] However, under this structure, when it rains heavily or the car is washed under high pressure, the water column will impact the sealing strip and deform it, and then a gap will be formed at the contact position between the sealing strip and the gutter or the car roof. The water column will shoot into the gutter from the gap, causing the water in the gutter to be shot and produce irregular water splashes, which will bounce to the top cover and fall onto the sunshade below, causing the risk of water leakage and getting the sunshade wet. The splashing of water will also produce a certain amount of noise, affecting the NVH performance of the whole vehicle. Utility Model Content
[0004] Based on this, it is necessary to provide a sunroof assembly and a car that can avoid the risk of water leakage and improve NVH performance.
[0005] A sunroof assembly is provided on a car roof, wherein the car roof is provided with a sunroof opening for accommodating the sunroof assembly; the sunroof assembly comprises:
[0006] Skylight glass;
[0007] A drainage member is covered on the outer peripheral edge of the skylight glass, and a gap is formed between the side of the drainage member away from the skylight glass and the skylight opening; a drainage port is formed on the drainage member, and the drainage port is located below the gap;
[0008] A sealing strip is disposed in the gap, and opposite side walls of the sealing strip are respectively in sealing cooperation with the drainage member and the skylight opening;
[0009] The sealing lip is arranged on a side of the sealing strip close to the drain outlet and extends toward the drain outlet.
[0010] In one of the embodiments, there is a gap between one end of the sealing lip close to the drain outlet and the drain outlet.
[0011] In one of the embodiments, the width of the gap is set to D1, and D1 ≥ 10 mm.
[0012] In one of the embodiments, a water absorbing member is provided in the drain port, and the position of the water absorbing member corresponds to the gap.
[0013] In one of the embodiments, the thickness of the water absorbing member is set to D2, 30mm≥D2≥10mm.
[0014] In one of the embodiments, one end of the sealing lip close to the drain port abuts against the water absorbing member.
[0015] In one of the embodiments, a stopper is provided on one end of the drainage member close to the skylight opening, and the stopper extends from the drainage member toward the direction of the automobile roof.
[0016] In one of the embodiments, an extension portion is provided on the water absorbing member, and the extension portion is fixedly connected to the blocking portion.
[0017] In one embodiment, the height of the extending portion is set to H1, and the height of the blocking portion is set to H2, and the relationship between H1 and H2 satisfies H1<H2.
[0018] The present application also provides a car, comprising the sunroof assembly described in any one of the above embodiments.
[0019] Compared with the prior art, the sunroof assembly cuts off the movement line of the water splashed by shooting in the drainage groove by setting the sealing lip edge. The water splash is blocked by the sealing lip edge, and the splashed water will not splash onto the top cover and flow into the sunshade, thus solving the problem of water leakage in the sunroof. Secondly, the blocking of the sealing lip edge avoids the noise caused by splashing water, reduces NVH noise, and improves the NVH performance of the car. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0030] See also Figures 1 to 3 The present application provides a car, wherein a sunroof opening 20 is provided on a car roof 10, and the sunroof opening 20 is used to accommodate a sunroof assembly 40, that is, the sunroof assembly 40 is installed on the sunroof opening 20. A sunshade 30 is provided below the sunroof assembly 40.
[0031] See also Figures 2 to 3 The sunroof assembly 40 includes a sunroof glass 41, a drain member 42, a sealing strip 43 and a sealing lip 44. Specifically, the drain member 42 is coated on the outer peripheral edge of the sunroof glass 41, and a gap 45 is formed between the side of the drain member 42 away from the sunroof glass 41 and the sunroof opening 20. The sealing strip 43 is arranged in the gap 45, and the sealing strip 43 is respectively sealed with the drain member 42 and the sunroof opening 20. A drain port 421 is provided on the drain member 42, and the drain port 421 is located below the gap 45. The sealing lip 44 is arranged on one side of the sealing strip 43 close to the drain port 421, and extends in the direction of the drain port 421. The extended sealing lip 44 is separated in the middle of the drain port 421, and the moving line of the splashing water is blocked by the sealing lip 44, the moving line of the splashing water is shortened, and the noise caused by it is reduced. Secondly, the sealing lip 44 prevents water from splashing out from the gap 46 between the drainage member 42 and the ceiling, thereby preventing the sunshade 30 from being splashed.
[0032] Furthermore, there is a gap 46 between the end of the sealing lip 44 close to the drain outlet 421 and the drain outlet 421, that is, the sealing lip 44 does not directly abut against the drain outlet 421, thereby avoiding friction and wear between the sealing lip 44 and the drain outlet 421 during driving, thereby improving the service life of the sealing lip 44.
[0033] Preferably, the width of the gap 46 is set to D1, and D1 ≥ 10 mm. The specific value may be 10 mm, 15 mm, 20 mm, 25 mm, etc. Of course, the corresponding value may also be selected according to the actual situation.
[0034] Furthermore, a water absorbing member 47 is provided in the drain port 421, and the position of the water absorbing member 47 corresponds to the position of the gap 45. By providing the water absorbing member 47, after the water column enters from the gap 46 between the sealing strip 43 and the drain member 42 or the skylight opening 20, it hits the water absorbing member 47, and is then fully or partially absorbed by the water absorbing member 47, and no water splashes, or only a small amount of water splashes and is blocked by the sealing lip 44. By providing the water absorbing member 47, the splashing of water is greatly suppressed, the noise generated by the splashing of water is reduced, and the NVH performance of the whole vehicle is improved.
[0035] Preferably, the thickness of the water absorbing member 47 is set to D2, 30 mm ≥ D2 ≥ 10 mm. Under such a numerical range, the thickness of the water absorbing member 47 is neither too thin to absorb water splashes to the maximum extent, nor too thick to cause waste of materials. The value of D2 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc., and of course, the corresponding value can be selected according to the actual situation.
[0036] Furthermore, the water absorbing member 47 may be made of sponge, foaming material, etc. In this embodiment, the water absorbing member 47 is made of sponge, and is preferably EPDM closed-cell foam.
[0037] In this embodiment, one end of the sealing lip 44 close to the drain port 421 abuts against the water absorbing member 47. Since the material of the water absorbing member 47 will not cause wear to the sealing lip 44, the abutment can better block water splashes and prevent water splashes from splashing out from the matching point of the two.
[0038] In one embodiment, a stopper 422 is provided on one end of the drainage member 42 close to the skylight opening 20 to prevent the water level in the drainage port 421 from being too high and leaking out. Specifically, the stopper 422 is formed by the end of the drainage member 42 extending toward the automobile roof 10, and there is a distance between the end of the stopper 422 close to the automobile roof 10 and the roof, so that the two do not contact each other to avoid interference.
[0039] Furthermore, the water absorbing member 47 is provided with an extension portion 471, the position of the extension portion 471 corresponds to the position of the stopper 422, and the extension portion 471 is fixedly connected to the stopper 422. Specifically, the extension portion 471 is fixedly connected to the stopper 422 at a position corresponding to one side of the drain port 421. Through the setting of the extension portion 471, even if there is still water splashing to this position, it can still be absorbed by the extension portion 471, ensuring that no water splashes out to wet the sunshade curtain 30. The extension portion 471 and the stopper 422 can be fixedly connected by bonding, clamping, etc. In this embodiment, the fixing is achieved by bonding, and the processing operation is simple.
[0040] In this embodiment, the extending portion 471 and the water absorbing member 47 are made of the same material and are an integral structure.
[0041] Furthermore, the height of the extension part 471 is set to H1, and the height of the stopper part 422 is set to H2, and the relationship between H1 and H2 satisfies that H1<H2. That is, the height of the extension part 471 is slightly lower than the height of the stopper part 422, and even if the extension part 471 accidentally interferes with the ceiling and is squeezed, the water squeezed out of the extension part 471 will be blocked by the stopper part 422 and flow back into the drain port 421, ensuring that no water leaks out.
[0042] In this embodiment, the sealing strip 43 is a flexible structure and can be made of materials such as rubber and resin. This embodiment preferably uses EPDM material, which is realized by extrusion and spraying process, which can effectively reduce noise, waterproof and dustproof. Preferably, the material of the sealing lip 44 is set to be the same as that of the sealing strip 43, and the sealing lip 44 and the sealing strip 43 are an integrated structure for easy processing. Of course, in other embodiments, the sealing lip 44 and the sealing strip 43 can also be set to be separated, and the material can also be set to be the same as that of the sealing strip 43, which is selected according to actual needs.
[0043] In this embodiment, the drainage member 42 is a flexible structure and can be made of rubber, resin, etc. It can be integrally molded on the skylight glass 41 by injection molding, or can be covered on the outer edge of the skylight glass 41 by sleeve connection or bonding.
[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
