Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction machinery cabs, in particular to a waterproof structure of an engineering vehicle cab door and a cab. Background Technique
[0002] The working environment of engineering vehicles is relatively harsh. After working for a period of time, a lot of dust and sediment adhere to the body and glass. Therefore, it is necessary to wash the vehicle frequently to ensure the cleanliness of the body and glass. At present, the cab doors of most engineering vehicles have similar structures, and the sealing structure is basically a sealing rubber strip. Because the sealing structure is relatively simple and has high flexibility, it is easy to deform when facing the high-pressure water flow of a high-pressure water gun, and then the sealing rubber strip loses its sealing and waterproof function, resulting in water seepage in the cab. Because the front edge of the cab door frame is relatively easy to be washed, when the cab is cleaned with a high-pressure water gun, the water seepage at the front edge of the cab door frame is relatively serious, and the water seeps into the cab, affecting the cleanliness and driving experience inside the cab; and if a large amount of water seeps in, it takes time to clean, affecting the washing work efficiency of the driver and causing time waste. Content of the Utility Model
[0003] The purpose of the utility model is to provide a waterproof structure of an engineering vehicle cab door and a cab. When the cab is washed with a high-pressure water gun, the water baffle can effectively block the high-pressure water flow from impacting the front border of the door frame sealing rubber strip, thereby reducing the water seepage amount in the cab during car washing, and improving the cab cleanliness and driving experience.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a waterproof structure of an engineering vehicle cab door, including a door frame sealing rubber strip and a water baffle. The door frame sealing rubber strip is arranged in a rubber strip installation groove on the cab door frame. The water baffle is arranged on the cab frame and is distributed along the edge of the front border of the cab door frame. When the cab door is in a closed state, the water baffle is adjacent to the front border of the door frame sealing rubber strip.
[0005] Preferably, the cross-section of the water baffle is in an ∠ shape.
[0006] Further, the upper and lower ends of the water baffle are in a through state.
[0007] Further, the water baffle is an integral sheet metal part.
[0008] Further, the water baffle is fixedly connected to the side surface of the cab frame by welding.
[0009] A cab includes the waterproof structure of the engineering vehicle cab door described above.
[0010] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple and convenient for processing and manufacturing; the water baffle is fixedly arranged on the cab frame. When the cab door is in the closed state, the water baffle is located on the front side of the front border of the door frame sealing strip. Therefore, when washing the cab with a high-pressure water gun, through the blocking effect of the water baffle, it can effectively prevent the high-pressure water flow from directly impacting the front border of the door frame sealing strip, thereby greatly reducing the water seepage volume in the cab during car washing. With less water seepage in the cab, it can improve the cleanliness and the experience of the cab. At the same time, due to less water seepage, the driver does not need to spend a lot of time cleaning the water seepage, which is conducive to improving the car washing work efficiency of the driver; the water baffle is an integral sheet metal part, which is convenient for processing and manufacturing; the upper and lower ends of the water baffle are in a through state, so that when washing the car, there will be no water accumulation between the water baffle and the cab frame, effectively avoiding the problem of rust.

[0017] The following will combine specific embodiments and the attached Figures 1-4 , and clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only partial preferred embodiments of the present utility model, rather than all embodiments. Those skilled in the art can make similar deformations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0018] The cab 1 of an engineering vehicle has a main structure of a cab frame 11. The accessory components on the cab 1, such as the cab door 2 and some glasses, are directly installed on the cab frame 11. Among them, the cab door 2 is usually hinged on one side of the cab 1 by a hinge. The cab door 2 includes a cab door frame 21.
[0019] The utility model provides a waterproof structure for the cab door of an engineering vehicle (as Figure 1 shown), which includes a door frame sealing strip 3 and a water baffle 4. The door frame sealing strip 3 is a commonly used technical product in the existing sealing technology field, so the detailed structure of the door frame sealing strip 3 will not be described in detail. In actual application, the door frame sealing strip 3 is arranged in a strip installation groove on the cab door frame 21, and the water baffle 4 is arranged on the cab frame 11 and is distributed along the edge of the front border of the cab door frame 21. The water baffle 4 is distributed along the edge of the front border of the cab door frame 21, so as to facilitate the water baffle 4 to correspond to the entire upper and lower range of the front edge of the cab door frame 21. When the cab door 2 is in a closed state, the water baffle 4 is adjacent to the front border 31 of the door frame sealing strip 3. When installing and fixing the water baffle 4 on the cab frame 11, first close the cab door 2, and then make the rear side of the water baffle 4 as close as possible to the front side of the front border 31 of the door frame sealing strip 3, so as to determine the installation and fixing position of the water baffle 4. During the car washing process, the water baffle 4 is located on the front side of the front border 31 of the door frame sealing strip 3. Therefore, when flushing the cab 1 with a high-pressure water gun, through the blocking effect of the water baffle 4, the high-pressure water flow can be effectively prevented from directly impacting the front border 31 of the door frame sealing strip 3, thereby greatly reducing the water seepage volume in the cab 1 when washing the car. The water seepage volume in the cab 1 is small, which can effectively maintain the cleanliness in the cab 1. At the same time, the time for the driver to clean the water seepage is greatly reduced, which is conducive to improving the car washing work efficiency of the driver.
[0020] On the basis of the above embodiment, the specific implementation manner of the water baffle 4 is: the cross section of the water baffle 4 is in an ∠ shape, and the water baffle 4 is an integral sheet metal part. In the actual processing process, the water baffle 4 can be processed and formed by a sheet metal mold, which not only has high processing accuracy but also high processing efficiency.
[0021] To prevent water from accumulating between the water baffle 4 and the cab frame 11, here, the upper and lower ends of the water baffle 4 are in a through state. During the car washing process, the water flowing in from the upper part of the water baffle 4 will automatically flow out from its lower part, so that no water accumulation phenomenon will occur. If there is no water accumulation inside the water baffle 4, the rust problem can be effectively eliminated.
[0022] In practical applications, to ensure the impact resistance of the water baffle 4, here, the water baffle 4 is directly fixedly connected to the side of the cab frame 11 by welding. When welding the water baffle 4, both outer ends of the water baffle 4 are welded and fixedly connected to the side of the cab frame 11.
[0023] The present utility model also provides a cab, which includes the waterproof structure of the engineering vehicle cab door described above.
[0024] In the present utility model, "front", "rear", "upper", "lower", "left", and "right" are all relative positions used for conveniently describing the positional relationship, and therefore cannot be understood as absolute positions to limit the protection scope.
[0025] Except for the technical features described in the specification, they are all known technologies to those skilled in the art.
[0026] As described above, the preferred embodiments and examples of the present utility model have been described in detail in conjunction with the drawings. However, the present utility model is not limited to the above embodiments and examples. For those of ordinary skill in the art in this technical field, without departing from the concept of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
