Description

Technical Field

[0001] The present invention relates to the technical field of automotive glass windows, and particularly to a drainable glass window assembly. Background Art

[0002] When driving in the rain, it is a common phenomenon that rainwater pours back into the vehicle compartment from the window, especially at the movable glass panel of a sliding glass window. This is more prominent because the rainwater deposited on the aluminum profile will overflow over the sliding rail and enter the vehicle compartment, and the shaking and bumping during driving will exacerbate this phenomenon. Generally, in order to reduce the phenomenon of rainwater backflow, an overflow notch is provided on the outer side of the aluminum profile relative to the sliding rail. However, this method has a very weak effect on the window. Mainly, during vehicle driving, frequent speed changes, such as acceleration and deceleration, will concentrate the rainwater at the head or tail of the aluminum profile, rather than evenly dispersing it. Unless the overflow notches are sufficient in number or width, it is difficult to drain the rainwater, and it is difficult to drain it completely. If the overflow notches are numerous or wide, it will affect the appearance, strength, and sliding effect of the profile.

[0003] In the actual production of sliding windows, considering the problem of rainwater backflow, between the means of "drainage" and "blockage", more choices are made for "blockage", that is, to improve the seal between the movable (slidable) glass part and the aluminum profile, such as adding a water-blocking rubber strip, increasing the height of the slide rail to increase the sealing area, etc. However, these are all temporary solutions. There is an urgent need for a glass window assembly with stable and thorough drainage. Summary of the Invention

[0004] The purpose of the present invention is to provide a drainable glass window assembly to solve the problem of poor and incomplete drainage of existing sliding glass windows.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: A drainable glass window assembly includes a fixed glass, an upper profile, a lower profile, and a movable glass. The fixed glass is provided with a window. The upper profile and the lower profile are respectively arranged in parallel at the upper edge and the lower edge of the window. The fixed glass is slidably connected to the upper profile and the lower profile through sliding rails. Among them, the lower profile is provided with a drainage structure, and the drainage structure includes a water storage cavity, a rapid drainage port, a windproof drainage buckle, a pressure relief hole, and a water inlet hole. The water storage cavity is arranged inside the lower profile. The rapid drainage port is arranged on the outer side of the lower profile and is communicated with the water storage cavity. The windproof drainage buckle is installed on the rapid drainage port. The pressure relief hole and the water inlet hole are both arranged at the top of the lower profile and are communicated with the water storage cavity. One end of the water inlet hole is communicated with the sliding track of the lower profile.

[0006] A further technical solution is that the windproof drainage buckle includes a housing, a bottom plate and an elastic flap. The housing and the bottom plate are buckled with each other to form an interface communicating with the quick drainage port. A drain opening is provided on one side of the bottom plate, and one end of the elastic flap is installed on the bottom plate and adapted to the drain opening.

[0007] A further technical solution is that the elastic flap is a hard plastic sheet.

[0008] A further technical solution is that auxiliary drainage holes are also provided on the lower profile, and the openings of the auxiliary drainage holes are close to the outer surface of the fixed glass.

[0009] A further technical solution is that a limiting block for the movable glass is provided on the lower profile, and a part of the limiting block is located above the pressure relief hole.

[0010] A further technical solution is that reinforcing ribs are provided in the water-containing cavity.

[0011] A further technical solution is that the water inlet hole extends to the inner top rounded corner of the lower profile.

[0012] A further technical solution is that a positioning plate adapted to the quick drainage port is provided on the inner side of the lower profile.

[0013] A further technical solution is that a filter screen is provided on the water inlet.

[0014] Compared with the prior art, at least one of the following beneficial effects can be achieved by the present invention: The present invention provides a drainage glass window assembly. By utilizing the position conditions of the lower profile, the rainwater on the movable glass will automatically fall onto it under the action of gravity, and with the help of the central water inlet hole, during the driving process of frequently increasing and decreasing the vehicle speed, the rainwater moving back and forth will pass through the water inlet hole and fall into the water-containing cavity, ensuring the timely and effective drainage of the rainwater on the glass part by means of the driving dynamics of the vehicle itself.

[0015] In addition, a windproof drainage buckle is installed on the quick drainage port of the lower profile to achieve the effect of discharging water without letting in wind. One is to prevent the wind generated by the vehicle speed and the strong wind in rainy weather from pouring back into the quick drainage port, affecting normal drainage; the other is to reduce the wind noise generated by the quick drainage port affected by strong wind.

[0016] Combined with the effect that the windproof drainage buckle allows water to drain out but not air to enter, which is similar to a check valve, it proves by contradiction the important role of the water storage cavity. Generally, there is not much rainwater to be drained that is distributed on the lower profile and retained. It is very difficult for this rainwater to directly break through the one-way blocking effect of the windproof drainage buckle. However, the water storage cavity can continuously store water and reach a certain water storage capacity during rainy weather, and then generate sufficient water pressure to break through the one-way blockade of the windproof drainage buckle for drainage. The water storage cavity and the windproof drainage buckle complement each other and are indispensable in the use of this window, jointly ensuring that the window can achieve the windproof and drainage effects relying solely on a simple mechanical structure.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Embodiment 1: In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a drainable glass window assembly includes a fixed glass 1, an upper profile 2, a lower profile 3, and a movable glass 4. The fixed glass 1 is provided with a window opening. The upper profile 2 and the lower profile 3 are respectively arranged in parallel at the upper edge and the lower edge of the window opening. The fixed glass 1 is slidably connected to the upper profile 2 and the lower profile 3 through sliding rails 5 respectively. The lower profile 3 is provided with a drainage structure, which includes a water storage cavity 6, a quick drainage port 7, a windproof drainage buckle 8, a pressure relief hole 9, and a water inlet hole 10. The water storage cavity 6 is arranged inside the lower profile 3. The quick drainage port 7 is arranged on the outer side of the lower profile 3 and communicates with the water storage cavity 6. The windproof drainage buckle 8 is installed on the quick drainage port 7. The pressure relief hole 9 and the water inlet hole 10 are both arranged at the top of the lower profile 3 and communicate with the water storage cavity 6. One end of the water inlet hole 10 communicates with the sliding track of the lower profile 3.

[0030] This window assembly belongs to the structure of a window within a window, that is, a fixed glass 1 is installed on the window opening of a vehicle, and a movable glass 4 is installed on the window opening of the fixed glass 1. Such a window structure greatly limits the specifications of the upper profile 2 and the lower profile 3. The width cannot be comparable to that of ordinary window aluminum profiles because its width needs to match the thickness of the fixed glass 1.

[0031] It can be seen that under the limitation of the profile's own specifications, it is impossible to use the method of "blocking" to ensure extreme sealing and the method of "draining" to set enough or wide openings. The window of this product converts the heat insulation cavity of the aluminum profile itself into a water storage cavity 6 for use, and a water inlet hole 10 is designed at the middle position of the lower profile 3. The rainwater on the movable glass 4 will automatically fall onto the lower profile 3 under the action of gravity. During the driving process of frequently accelerating and decelerating the vehicle speed, the moving rainwater will pass through the water inlet hole 10 and fall into the water storage cavity 6. Therefore, with the help of the centered water inlet hole 10 and the driving dynamics of the vehicle itself, the rainwater on the movable glass 4 part is discharged in a timely and effective manner.

[0032] In addition, a windproof drainage buckle 8 is installed on the quick drainage port 7 of the lower profile 3 to achieve the effect of water discharge without wind entering. One is to prevent the wind generated by the vehicle speed and the strong wind in rainy weather from flowing back into the quick drainage port 7, affecting normal drainage; the other is to reduce the wind noise generated by the quick drainage port 7 affected by strong wind. When the quick drainage port 7 is draining water, the pressure relief hole 9 will balance the pressure inside and outside the water storage cavity 6 to ensure smooth drainage.

[0033] It should be noted that: Combining the effect of the windproof and drainage buckle 8 where water flows out but air does not enter, which is similar to a check valve, it proves by contrast the important role of the water storage cavity 6. Generally, there is not much rainwater to be drained that remains on the lower profile 3, and it is difficult for this small amount of rainwater to directly break through the one-way blocking effect of the windproof and drainage buckle 8. However, the water storage cavity 6 can continuously store water during rainy weather until it reaches a certain water storage level, and then generate sufficient water pressure to break through the one-way blockade of the windproof and drainage buckle 8 for drainage. The water storage cavity 6 and the windproof and drainage buckle 8 complement each other and are both indispensable in the use of this vehicle window, jointly ensuring that the vehicle window can achieve the effects of windproof and drainage relying solely on a simple mechanical structure.

[0034] Embodiment 2: Based on the above embodiment, in this embodiment, as Figure 5 shown, the windproof and drainage buckle 8 includes a housing 11, a bottom plate 12, and an elastic flap 13. The housing 11 and the bottom plate 12 are buckled together to form an interface that communicates with the quick drainage port 7. One side of the bottom plate 12 is provided with a drain opening, and one end of the elastic flap 13 is installed on the bottom plate 12 and is adapted to the drain opening.

[0035] The windproof and drainage buckle 8 is directly buckled on the quick drainage port 7. Under the water pressure inside the water storage cavity 6, it will break through the blockage of the elastic flap 13 on the drain opening, and the rainwater will be discharged smoothly. When there is no water or little water, the elastic flap 13 returns and blocks the drain opening, preventing strong winds from the outside from affecting the vehicle window. For example, preventing strong winds from flowing back into the quick drainage port 7 and affecting the normal drainage of the lower profile 3 into the water storage cavity 6; reducing the wind noise generated by the quick drainage port 7 affected by strong winds. Preferably, the elastic flap 13 is a hard plastic sheet.

[0036] The hard plastic sheet has its own elasticity and can automatically reset. Moreover, it has a low cost and is easy to replace.

[0037] Preferably, the lower profile 3 is further provided with an auxiliary drainage hole 14, and the opening of the auxiliary drainage hole 14 is close to the outer surface of the fixed glass 1.

[0038] When there is no water or little water in the water storage cavity 6, the elastic flap 13 returns and blocks the drain opening. Mainly when there is little water, the auxiliary drainage hole 14 can drain water independently on the basis that the quick drainage port 7 does not drain water. Moreover, the auxiliary drainage hole 14 is close to the outer surface of the fixed glass 1 and is hardly affected by the wind force.

[0039] Preferably, the lower profile 3 is provided with a limiting block 15 for the movable glass 4, and part of the limiting block 15 is located above the pressure relief hole 9.

[0040] The limiting block 15 is used to limit the pushing and pulling position of the movable glass 4 and to block the pressure relief hole 9 to prevent the water in the water storage cavity 6 from splashing out due to inertia during vehicle acceleration or deceleration.

[0041] Preferably, reinforcing ribs 16 are provided in the water storage cavity 6.

[0042] The reinforcing ribs 16 serve to strengthen the profile.

[0043] Preferably, the water inlet hole 10 extends to the inner top rounded corner of the lower profile 3.

[0044] When the inner side of the lower profile 3 is attached to the fixed glass 1, a water storage groove dead angle will be formed between the inner top rounded corner of the lower profile 3 and the fixed glass 1. If the rainwater here is not drained in time, then for a long time, this part of the rainwater will erode the sealant between the lower profile 3 and the fixed glass 1. Therefore, the water inlet hole 10 extends to the inner top rounded corner of the lower profile 3, which can effectively drain all the rainwater in this part.

[0045] Preferably, a positioning plate 17 adapted to the quick drainage port 7 is provided on the inner side of the lower profile 3.

[0046] The function of the positioning plate 17 is to ensure that the quick drainage port 7 is not blocked by the fixed glass 1 through the limitation of the positioning plate 17 when the lower profile 3 is installed.

[0047] Preferably, a filter screen 18 is provided on the water inlet 10.

[0048] The filter screen 18 can filter out foreign impurities and prevent the water path of the window drainage structure from being blocked.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
