Description

Technical Field

[0001] This utility model relates to the field of special vehicle technology, specifically to the structure of an all-terrain vehicle driver's cab. Background Technology

[0002] An all-terrain vehicle is a special type of vehicle used in terrains such as flat land, mountains, plateaus, riverbanks, deserts, and ravines. (See reference) Figure 1 The existing cab structure results in extremely poor maintainability. The air intake and exhaust vents are too close to the engine compartment's air intake, obstructing engine air intake and causing significant noise and discomfort in the cab. Secondly, when the all-terrain vehicle is wading through water, any water seeping into the cab requires a water pump to remove it outside to ensure occupant safety. The drain outlet is located at the top, which can affect drainage in emergencies if the pipe is not long enough, and water may leak directly into the cab from the top if the pipe detaches. Finally, the existing cab structure blocks the engine's air intake, affecting the engine's air intake volume. Summary of the Invention

[0003] The purpose of this utility model is to provide a driver's cab structure for an all-terrain vehicle, which reduces noise in the driver's cab, increases engine air intake, and improves drainage by rearranging the top structure.

[0004] The technical solution of this utility model is as follows: a driver's cab structure for an all-terrain vehicle, which has an engine at its rear end, a roof, an air intake and exhaust port at the front of the roof, and an inclined air intake slot at the rear of the roof. The inclination angle of the air intake slot is 11 degrees, and air intake ports are provided on the side walls of the slot.

[0005] Preferably, the air intake groove includes a sloping groove section and an expanding groove section connected in sequence; the sloping groove section has an inclination angle of 11 degrees; the expanding groove section has a rectangular cross-section, and its depth and width are both greater than the corresponding dimensions of the sloping groove section.

[0006] Preferably, the inclined groove includes an inclined bottom surface and two triangular side surfaces; the bottom surface forms the 11-degree inclination angle; the two side surfaces are respectively connected to the two sides of the bottom surface.

[0007] Preferably, the width of the expanded diameter groove section is greater than the width of the engine air inlet.

[0008] Preferably, the bottom edge height of the engine exhaust port is not lower than the bottom edge height of the inclined groove section. The beneficial effects of this utility model are as follows: By redesigning the roof structure, the original air intake and exhaust ports are moved forward, the drainage outlet is moved to the left side of the vehicle, and a sloping channel is added at the original engine exhaust port location. This reduces noise in the driver's cab, improves drainage, and ensures sufficient air intake for the engine. Attached Figure Description

[0009] To more clearly illustrate the technical solutions in the specific embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0012] Reference Figure 2 This utility model describes the external structure of the driver's cab. Air intake and exhaust ports 1 are located near the front of the cab roof, and drain ports 2 extend from both sides of the cab roof. An 11-degree sloping groove is added to the rear of the cab roof to form an air intake slot 4. An engine air intake port 3 is fixed at the air intake slot. Since all-terrain vehicle windows are fixed and cannot be opened, air intake and exhaust ports are needed to exchange oxygen for the occupants in the cab. This driver's cab design places the air intake and exhaust ports near the front of the cab roof, which reduces engine noise. When the all-terrain vehicle is wading through water, if water seeps into the cab, a water pump is needed to drain the water outside the cab to ensure the safety of the occupants. The drain ports are located on both sides of the cab for more efficient drainage. Because the existing driver's cab structure blocks the engine air intake, affecting the engine's air intake, this utility model adds an 11-degree sloping groove at the rear of the cab roof to ensure sufficient air intake for the engine.

[0013] Example: This example provides an optimized all-terrain vehicle driver's cab structure. The engine is located at the rear of this cab structure. The innovation of the driver's cab structure mainly focuses on the roof layout, specifically including: Optimized air intake and exhaust port layout: The air intake and exhaust port 1 is located in the front area of ​​the roof. This position is far from the rear engine, which can effectively reduce the intensity of engine noise transmitted to the driver's cabin and improve driving comfort.

[0014] Optimized drainage system layout: Drain outlets are located on the two sides of the driver's cab roof, rather than on the roof. This lateral drainage design avoids the risk of water leaking directly into the cab if the top drain pipe comes loose or is insufficient in length, making the drainage path more direct and reasonable, and improving safety when driving through water.

[0015] Engine intake support structure: At the rear of the roof, there is a specially designed inclined slot with an angle of 11 degrees, namely the intake slot 4. The intake slot 4 is directly opposite the engine air intake 3 below, and its function is to form an unobstructed air intake channel to ensure that the engine receives sufficient air volume and avoid the obstruction of air intake by the original driver's cab structure.

[0016] Working Principle: The structure of this invention effectively reduces noise. The forward-positioned intake and exhaust ports 1 utilize the principle of distance attenuation to effectively isolate engine noise. Reasonable drainage is achieved through the side-positioned drain port 2, establishing a more reliable and efficient drainage path and reducing the risk of water ingress into the cab. Power Guarantee: The 11-degree inclined intake slot 4 provides a dedicated intake channel for the engine intake port 3, completely solving the problem of air intake obstruction and ensuring engine power performance.

[0017] In summary, the all-terrain vehicle driver's cab structure of this embodiment significantly improves the vehicle's quietness, safety, and power reliability through the rearrangement and innovative design of key functional components on the roof.

[0018] The above provides a detailed description of the all-terrain vehicle driver's cab structure provided by this utility model. Specific examples have been used to illustrate the structure and working principle of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
