Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an embedded door top water-blocking structure and a commercial vehicle. Background Technology

[0002] The top of commercial vehicle doors is an area where rainwater easily seeps in. Traditional water-blocking structures include:

[0003] Exposed water deflector: Traditional car door water deflectors are usually exposed at the top of the door and contact the car body through a sealing strip to prevent rainwater from entering the car.

[0004] Internal water-cutting barrier structure: Some technologies adopt an internal water-cutting barrier structure, which prevents rainwater from entering the interior of the car door by contacting the window glass with the water-cutting lip.

[0005] Waterproof eaves structure at the top of the door: Some designs have a waterproof eaves at the top of the door, which is a structure that directs water out of the vehicle.

[0006] The above three types of water deflectors have the following drawbacks: exposed water deflector structures affect the overall aesthetics of the vehicle body; exposed designs increase wind resistance during vehicle operation, reducing fuel economy. Traditional water deflector structures cannot effectively block rainwater when the doors are open, easily allowing rainwater to flow into the vehicle. Complex structures: some water deflector structures have complex designs, increasing manufacturing and assembly difficulties. These problems urgently need to be addressed. Utility Model Content

[0031] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] To address the problems existing in the prior art, this application provides an embedded door top water-blocking structure and a commercial vehicle.

[0033] like Figures 1-4 As shown, an embedded water-blocking structure at the top of a car door is provided to prevent external water from entering the vehicle through the joint between door assembly A and door frame assembly B (i.e., the joint gap between door assembly A and door assembly B). Door assembly A is rotatably connected to door assembly B, and door assembly A can be flipped upwards. The water-blocking structure includes a water-receiving groove 1, a water-blocking strip 2, and a sealing strip 3. The water-receiving groove 1 is located inside door assembly B and along the joint. One groove wall is located along the edge of door assembly B and is used for sealing connection with door assembly B. The other groove wall is located along the edge of door assembly A and is spaced from door assembly A. When door assembly A is in the closed state, it can be sealed with door assembly A by the sealing strip 3. The water-blocking strip 2 is located inside the water-receiving groove 1, and one edge is located along the edge of door assembly A and is sealed, such as by welding or bonding. The other edge can form a sealed connection with the water-receiving groove 1 when door assembly A is in the open state.

[0034] This utility model discloses an embedded water-blocking structure for the top of a car door. Based on the water-receiving groove 1, water-blocking strip 2, and sealing strip 3 installed inside the vehicle, water is blocked at the junction of door assembly A and door assembly B. This can reduce the wind resistance of the vehicle. The water-receiving groove 1 and water-blocking strip 2 work together to block water when door assembly A is open, and the water-receiving groove 1 and sealing strip 3 work together to block water when door assembly A is closed, thus improving the water-blocking effect. The embedded water-blocking structure of this utility model has a simple structure and is easy to process and assemble.

[0035] In some preferred embodiments, such as Figures 2-4 As shown, the water receiving groove 1 is a groove-shaped structure formed by bending a flat plate; it is fastened at the joint of door assembly A and door assembly B. When door assembly A is closed, the water receiving groove 1 is fastened to the gap between door assembly A and door assembly B, and the groove side wall adjacent to door assembly B is sealed to door assembly B, such as by welding or bonding. The groove wall on the other side is sealed to door assembly A by sealing strip 3, thereby forming a seal at the joint of door assembly A and door assembly B, which can prevent external water from entering the vehicle. When door assembly A is open, the water baffle 2 can abut against the inner wall of the water receiving groove 1 and be sealed, such as against the bottom surface of the water receiving groove 1. Thus, a part of the water receiving groove 1 and the water baffle 2 form a barrier at the joint between door assembly A and door assembly B, preventing external water from entering the vehicle.

[0036] In some preferred embodiments, such as Figures 1-4 As shown, it also includes a guide plate 4; the guide plate 4 is located in the water receiving tank 1 and extends along the extension direction of the water receiving tank 1. One side is sealed and connected to the bottom surface of the water receiving tank 1, and the other side is located on the rotation path of the water baffle 2 and can overlap and seal with the water baffle 2; the setting of the guide plate 4 can reduce the size of the water baffle 2, thereby increasing the angle at which the door assembly A can be rotated and opened.

[0037] Preferably, the baffle plate 4 is made of an elastic material, such as an elastic metal sheet or elastic rubber; thus, on the one hand, when overlapping, the baffle plate 4 and the water-blocking strip 2 are elastically abutted to achieve a seal, and on the other hand, the angle at which the door assembly A can be rotated and opened can be further improved.

[0038] Preferably, the side of the guide plate 4 that overlaps with the water baffle 2 is inclined to form a water channel with the bottom surface of the water receiving tank 1. Thus, after external water flows in along the water baffle 2, it flows into the water channel formed by the water baffle 2 and is then guided out of the vehicle, preventing external water from flowing into the vehicle due to poor sealing at the overlap between the water baffle 2 and the guide plate 4. Optionally, the side of the guide plate 4 that connects to the bottom surface of the water receiving tank 1 is parallel to the side wall of the water receiving tank 1, while the other side is inclined upwards.

[0039] Preferably, when the guide plate 4 and the water-blocking strip 2 overlap, their surfaces fit together, thereby increasing the overlap area and improving the sealing effect.

[0040] In some preferred embodiments, such as Figures 3-4 As shown, the water-blocking strip 2 includes a first folding plate 21. One side of the first folding plate 21 is used to connect to the door assembly A, and the other side can block the joint when the door assembly A is closed. Based on this, it can block external water. For example, a water-storing groove is formed between the first folding plate 21 and the door assembly B. When the door assembly A is closed, external water entering from the joint will be temporarily stored in the groove. When the water level is higher than the joint, it will overflow from the joint, thereby reducing the amount of water entering the water-receiving groove 1 and preventing the sealing strip 3 from being in contact with water for a long time, which would reduce the sealing effect. Preferably, the edge of the first folding plate 21 connecting to the door assembly A is flush with the edge of the door assembly A to reduce the amount of water stored. Preferably, the first folding plate 21 is a 90° folding plate.

[0041] In some preferred embodiments, such as Figures 3-4 As shown, it also includes a second folding plate 22; one side edge of the second folding plate 22 is sealed to the first folding plate 21 and is inclined toward the door assembly B; the second folding plate 22 is inclined toward the door assembly B and then in the opposite direction.

[0042] In some preferred embodiments, such as Figures 2-4As shown, the water receiving groove 1 is connected to the door assembly B through the insertion groove 5. The insertion groove 5 is inserted into the frame of the door assembly B, thereby reducing the installation difficulty and improving the sealing effect; preferably, the insertion groove 5 and the water receiving groove 1 are integrally formed.

[0043] A commercial vehicle comprising the aforementioned right-embedded door top water-retaining structure.

[0044] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
