Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of special vehicle technology, in particular to a structure of a driver's cabin of an all-terrain vehicle. BACKGROUND
[0002] The all-terrain vehicle is a special vehicle used in flat land, mountain, plateau, river beach, desert, gully and other terrains. Figure 1 The existing driver's cabin structure is shown in the figure, the maintainability of the vehicle is very poor. The air inlet and outlet are close to the air suction port of the power cabin, which hinders the engine air intake, and the noise transmitted to the driver's cabin is large, and the comfort is poor. Secondly, when the all-terrain vehicle is involved in water, once the water seeps into the driver's cabin, the water pump needs to be used to drain the water outside the driver's cabin to ensure the safety of the personnel. The drainage port is arranged at the top end, and when the pipeline is not long enough in the event of an emergency, it will affect the drainage, and when the pipeline is removed, the water flow may directly leak into the driver's cabin from the top. SUMMARY
[0003] The purpose of the present application is to provide a structure of a driver's cabin of an all-terrain vehicle, which re-arranges the structure at the top end, so that the noise in the driver's cabin is small, the engine air intake is increased, and the drainage is reasonable.
[0004] The technical scheme of the present application is a structure of a driver's cabin of an all-terrain vehicle, the rear end of which is provided with an engine, comprising a roof, the top front of which is provided with an air inlet and outlet, and the top rear of which is provided with an inclined air inlet groove, the inclination angle of the air inlet groove being 11 degrees, and air inlets being arranged on the groove walls on both sides.
[0005] Preferably, the air inlet groove comprises a slanting groove section and a diameter expanding groove section connected in sequence; the inclination angle of the slanting groove section is 11 degrees; the cross section of the diameter expanding groove section is rectangular, and the depth and width thereof are both greater than the corresponding dimensions of the slanting groove section.
[0006] Preferably, the slanting groove comprises an inclined groove bottom surface and two triangular groove side surfaces; the groove bottom surface forms the 11-degree inclination angle; the two groove side surfaces are connected to the two side edges of the groove bottom surface, respectively.
[0007] Preferably, the width of the diameter expanding groove section is greater than the width of the engine air inlet.
[0008] Preferably, the bottom edge height of the engine air outlet is not less than the bottom edge height of the slanting groove section. The beneficial effects of the present application are that by re-arranging the structure of the roof, the original air inlet and outlet are moved forward, the drainage port is moved to the side end of the vehicle, and a slanting groove is added at the position of the original engine air outlet. The noise in the driver's cabin is reduced, the drainage is reasonable, and the engine air intake is ensured. BRIEF DESCRIPTION OF DRAWINGS
[0009] In order to more clearly illustrate the technical solutions in the specific embodiments of the present application, the drawings needed to be used in the following embodiment description will be briefly introduced. Obviously, the drawings described below only represent some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without creative effort on the basis of these drawings.
[0010] Figure 1 is a structural schematic diagram of the original cab; Figure 2 is a schematic diagram of the cab and engine installation of the present application; Reference signs: 1 - air inlet and exhaust port, 2 - water outlet, 3 - engine air inlet, 4 - air inlet groove. DETAILED DESCRIPTION
[0011] The present application will be further described below in combination with the drawings and specific embodiments, but it should not be understood that the scope of the subject matter described in the present application is limited to the following embodiments. Any modifications, replacements and changes made according to the ordinary technical knowledge and common practice in the art without departing from the technical idea of the present application are included in the scope of the present application.
[0012] Reference Figure 2 The air inlet and exhaust port 1 is arranged near the front of the cab roof, the water outlet 2 is arranged on the two side surfaces of the cab roof, and an 11-degree inclined groove is added to the rear of the cab roof to form an air inlet groove 4. The engine air inlet 3 is fixed at the air inlet groove. The windows of the all-terrain vehicle are fixed and cannot be opened. In order to supply oxygen to the personnel in the cab, an air inlet and exhaust port is needed to exchange oxygen. The air inlet and exhaust port of the present cab is designed to be located near the front of the cab roof. This design can reduce the noise from the engine. When the all-terrain vehicle is wading, water that has penetrated into the cab needs to be pumped out of the cab to ensure the safety of the personnel. The position of the water outlet is arranged on the two side surfaces of the cab, making the water drainage more reasonable. Since the existing cab structure blocks the air inlet of the engine, the air intake of the engine is affected. The present application opens an 11-degree inclined groove at the rear of the cab roof to ensure the air intake of the engine.
[0013] Embodiment: The present embodiment provides an optimized cab structure of an all-terrain vehicle. The rear end of the cab structure is provided with an engine. The innovation of the cab structure mainly focuses on the layout of the roof, which specifically includes: Optimized layout of air inlet and exhaust port: The air inlet and exhaust port 1 is arranged in the front region of the roof. This position is far away from the engine at the rear end, which can effectively reduce the intensity of the engine noise transmitted to the cab, and improve the driving comfort.
[0014] Drainage system layout optimization: the drain is arranged on the two sides of the top of the cab instead of the top. This lateral drainage design avoids the risk of water directly leaking into the cab when the top drain pipe falls off or is not long enough, making the drainage path more direct and reasonable, and improving the safety during water driving.
[0015] Engine air intake guarantee structure: a 11-degree inclined groove, i.e. air intake groove 4, is specially arranged at the rear of the roof. The air intake groove 4 is opposite to the engine air inlet 3 below, and its function is to form an unobstructed air intake channel to ensure that the engine has sufficient air intake and avoids the obstruction of the original cab structure to the air intake.
[0016] Working principle: the structure of the present application can effectively reduce noise, the air inlet and outlet 1 is moved forward, which effectively isolates the engine noise by using the principle of distance attenuation. Reasonable drainage, the drain 2 is placed on the side, establishing a more reliable and efficient drainage path, reducing the risk of water entering the cab. Guarantee power: the 11-degree air intake groove 4 provides a dedicated air intake channel for the engine air inlet 3, completely solves the problem of air intake obstruction, and ensures the power performance of the engine.
[0017] In summary, the cab structure of the all-terrain vehicle of the present embodiment significantly improves the quietness, safety and power reliability of the vehicle through the re-layout and innovative design of the key functional components of the roof.
[0018] The cab structure of the all-terrain vehicle provided by the present application is described in detail above, and specific examples are applied to describe the structure and working principle of the present application. The above examples are only used to help understand the method and core idea of the present application. It should be noted that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
