Description

Technical Field

[0001] The utility model is applied to the technical field of automobiles, and particularly relates to an upper waterproof structure of an inner swing door of a passenger car. Background Art

[0002] With the continuous advancement of science and technology and the continuous improvement of people's living standards, people's lives are becoming increasingly dependent on cars. Buses are an essential means of transportation in urban life. Existing bus rear doors often use a two-way swing door design. The swing door is controlled by a main air pump. When the engine is running, the air compressor operates, and the air compressor outlet is connected to the air tank. The air tank has a safety valve that automatically opens when the pressure inside the tank exceeds a certain level. Buses and large passenger vehicles generally use inner swing doors to open and close the vehicle. Brushes are installed at the upper edge of the vehicle's inner swing door. When the inner swing door is closed, a brush installed at the bottom of the inner swing door seals the upper door opening between the inner swing door and the vehicle floor, preventing dust from entering the vehicle interior and preventing air conditioning from leaking out.

[0003] Currently, the inner swing doors of buses on the market are generally not sealed and leak. Most of them use an upper water gutter and a brush structure at the bottom of the gutter to block most of the water. Although the gutter can drain most of the water and the brush can prevent water from flowing directly into the bus, in heavy rain, water can still flow along the brush into the inner door panel, forming water stains and water flow on the inner door panel, affecting the passenger driving experience and causing water accumulation on the bottom floor of the bus. Therefore, it is necessary to provide a waterproof structure for the upper part of the inner swing door of buses with the advantages of simple structure, easy disassembly and assembly, economical and practical, effectively solving the problem of water inflow and seepage at the upper part of the inner swing door, and ensuring the comfort and sealing of the interior environment of the bus. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the existing technology and provide a waterproof structure for the upper part of the inner swing door of a passenger car, which has the advantages of simple structure, easy disassembly and assembly, economy and practicality, effectively solves the problem of water inflow and seepage in the upper part of the inner swing door, and ensures the comfort and sealing of the interior environment of the car.

[0005] The technical solution adopted by the present invention is: the present invention includes an inner swing door, an upper curved arm, a mounting profile, a brush and a water-retaining rubber strip, the mounting profile is arranged at the upper end of the inner swing door, the lower end of the mounting profile is provided with a water-retaining profile, the bottom of the water-retaining profile is provided with a first mounting groove, the upper end of the brush is arranged in the first mounting groove, a second mounting groove is provided above the first mounting groove, the upper end of the water-retaining rubber strip is arranged in the second mounting groove, and the water-retaining rubber strip, the brush and the upper curved arm are arranged in sequence from the outside to the inside.

[0006] It can be seen from the above scheme that the water-retaining strip serves as the first line of waterproof defense, and the brush serves as the second line of waterproof defense. A double-layer waterproof structure is adopted. Even when it rains heavily, rainwater is difficult to flow into the door panel along the brush, ensuring that the car is clean and free of water stains. The overall structure is simple, easy to disassemble and assemble, and economical and practical.

[0007] A preferred solution is that a water flow trough is provided on the outer side of the installation profile, and the water flow trough is located above the outer side of the water retaining rubber strip.

[0008] A preferred solution is that the lower portion of the water-retaining rubber strip is turned outward, and the angle between the lower portion of the water-retaining rubber strip and the brush is 6 degrees.

[0009] A preferred solution is that the vertical length of the water-retaining rubber strip is greater than the vertical length of the brush.

[0010] A preferred solution is that the water-retaining rubber strip exceeds the upper edge of the inner swing door by 4 mm, and when the inner swing door is in a closed state, the water-retaining rubber strip overlaps the outer side of the upper edge of the inner swing door.

[0011] A preferred solution is that the installation profile is fixed by self-tapping screws from the lower part of the door frame, and the water retaining profile is connected and fixed to the installation profile by pre-welded bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figures 1 to 4 As shown, in this embodiment, the utility model includes an inner swing door 8, an upper curved arm 9, a mounting profile 1, a brush 2 and a water-retaining rubber strip 3, the mounting profile 1 is arranged at the upper end of the inner swing door 8, the lower end of the mounting profile 1 is provided with a water-retaining profile 4, the bottom of the water-retaining profile 4 is provided with a first mounting groove 5, the upper end of the brush 2 is arranged in the first mounting groove 5, a second mounting groove 6 is provided above the first mounting groove 5, the upper end of the water-retaining rubber strip 3 is arranged in the second mounting groove 6, the water-retaining rubber strip 3, the brush 2 and the upper curved arm 9 are arranged in sequence from the outside to the inside.

[0017] The brush 2 and the water-retaining strip 3 are both in a row structure and are distributed above the outer side of the inner swing door 8. The water-retaining strip 3 is inserted into the second mounting groove 6. The water-retaining strip 3 serves as the first line of waterproofing, and the brush 2 serves as the second line of waterproofing. A double-layer waterproof structure is adopted. Even when it rains heavily, it is difficult for rainwater to flow into the door panel along the brush 2, ensuring that the car is clean and free of water stains, and realizing double sealing of the outer water-retaining strip and the inner brush, thereby enhancing the water-retaining and sealing performance.

[0018] like Figures 1 to 4 As shown, in this embodiment, a water flow groove 7 is provided on the outside of the mounting profile 1, and the water flow groove 7 is located above the outside of the water retaining strip 3. When it rains, water on the door flows along the water flow groove 7 to drain to both sides of the door opening to prevent it from falling into the car or onto passengers.

[0019] like Figures 1 to 4 As shown, in this embodiment, the lower portion of the water-blocking strip 3 is turned outward, and the angle between the lower portion of the water-blocking strip 3 and the brush 2 is 6 degrees. The water-blocking strip 3 is naturally tilted to prevent the water-blocking strip 3 from being clamped when the inner swing door 8 is closed, which not only affects the appearance but also affects the water-blocking and sealing performance.

[0020] like Figures 1 to 4 As shown, in this embodiment, the vertical length of the water-retaining strip 3 is greater than the vertical length of the brush 2, achieving double sealing of the outer water-retaining strip and the inner brush, thereby enhancing the water-retaining and sealing performance.

[0021] like Figures 1 to 4 As shown, in this embodiment, the water-retaining rubber strip 3 exceeds the upper edge of the inner swing door 8 by 4 mm. When the inner swing door 8 is in a closed state, the water-retaining rubber strip 3 overlaps the outer side of the upper edge of the inner swing door 8, and rainwater cannot flow into the upper edge of the door panel, forming a first waterproof structure.

[0022] like Figures 1 to 4 As shown, in this embodiment, the installation profile 1 is fixed by self-tapping screws from the lower part of the door frame, and the water retaining profile 4 is connected and fixed to the installation profile 1 by pre-welded bolts.
