[0016] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] As Figure 1 shown, the embodiment of the present invention provides a vehicle. As Figure 1 and Figure 3 shown, it includes:

[0018] An air chamber 2, which is fixedly arranged in the vehicle engine compartment, is a sealed cavity formed by welding an air chamber bottom plate 3 parallel to the vehicle front bulkhead 5 and an L-shaped plate 8 perpendicular to the vehicle front bulkhead 5 on the vehicle front bulkhead 5;

[0019] An air conditioner air inlet 9, which is opened on the vehicle front bulkhead 5, and the interior of the air chamber 2 is communicated with the vehicle air conditioner through the air conditioner air inlet 9;

[0020] The natural wind inlet 1 is opened on the side surface of the front engine compartment of the vehicle and communicates with the air chamber 2;

[0021] A drainage structure is fixedly arranged at the bottom end of the air chamber 2, with one end communicating with the bottom of the air chamber 2 and the other end communicating with the outside of the vehicle.

[0022] In the embodiment of the present invention, the shape of the sealed cavity formed by welding the air chamber bottom plate 3 and the L-shaped plate 8 perpendicular to the vehicle front bulkhead 5 on the vehicle front bulkhead 5 can be of any shape. That is, in the embodiment of the present invention, the shape of the air chamber 2 is not limited, as long as there is a space for gas to flow in and it has airtightness to prevent gas leakage. For example Figure 1 The air chamber 2 shown in the cuboid structure. In some alternative examples, it can also be made into a sealed cavity with other shape structures such as a trapezoid or a cone according to the internal structure of the vehicle. In addition, the specific materials of the air chamber bottom plate 3 and the L-shaped plate 8 are not limited. For example: any solid material such as a metal material or a carbon fiber composite material that can be welded and can impede the flow of gas is not limited in the embodiment of the present invention. The setting of the air chamber 2 can prevent the air inlet connected to the air conditioner from being directly exposed to the environment, resulting in rainwater, sundries, etc. entering the air conditioner and causing the air conditioner to malfunction. In addition, in some alternative embodiments, the weld length between the air chamber bottom plate 3 and the L-shaped plate 8 perpendicular to the vehicle front bulkhead 5 and the vehicle front bulkhead 5 is small, and the spacing distance is large. Welding is minimized as much as possible while meeting the structural strength requirements to reduce the problem of the heat affected zone and the decline in protective performance caused by welding.

[0023] The above air conditioner air inlet 9 can be understood as a structure for introducing the gas in the air chamber 2 into the vehicle air conditioner. In the embodiment of the present invention, the specific form is not limited. For example, the air conditioner air inlet 9 can transport the gas in the air chamber 2 into the interior of the vehicle air conditioner through the combination of the air inlet and the air duct; it can also directly enter the air conditioner through the opening formed on the vehicle front bulkhead 5. At the same time, the shape type of the air conditioner air inlet 9 formed on the vehicle front bulkhead 5 is not limited. In some alternative embodiments, the air conditioner air inlet 9 can be a common rectangular, circular or square air inlet, or a grid-shaped air inlet can be used to increase the air flow area and efficiency. The embodiment of the present invention does not limit this. In addition, the position of the air inlet formed on the vehicle front bulkhead 5 can be any position within the range of the air chamber 2 on the vehicle front bulkhead 5, as long as the air in the air chamber 2 can flow in. The embodiment of the present invention does not limit its specific position.

[0024] The above-mentioned natural wind inlet 1 can be understood as a structure for introducing the air outside the vehicle into the air chamber 2. Similarly, the embodiments of the present invention do not limit the specific form. At the same time, the specific position of the side surface of the front cabin is not limited. The natural wind inlet 1 can be set on the front side of the front cabin, such as the grille part of the front of the vehicle, to directly inhale air when the vehicle is driving; the natural wind inlet 1 can also be set near the side window of the vehicle or above the door; the natural wind inlet 1 can also be set on the upper side of the front cabin according to some specially designed vehicles to enhance air circulation, etc. In addition, the embodiments of the present invention do not limit the shape type of the natural wind inlet 1, for example: square, circular, grid-shaped or other shapes, as long as it can allow external air to pass through, it can be used in the embodiments of the present invention.

[0025] The specific communication form between the natural wind inlet 1 and the air chamber 2 is not specifically limited in the embodiment of the utility model. A pipeline can be used or a tubular opening can be directly opened on the air chamber 2 to communicate with the outside, as long as the external air can enter the air chamber 2 from the natural wind inlet 1.

[0026] The drainage structure can be understood as a structure that uses gravity to collect and guide the liquid entering the air chamber 2 and discharge it to the outside of the vehicle, which can prevent rainwater and other liquids from entering the air inlet 9 of the air conditioner; the specific type and material of the drainage structure are not specifically limited in the embodiment of the utility model, for example: it can be used, for example Figure 3 The lower end of the air chamber 2 is provided with a certain inclination to cooperate with the gap 10 and the drainage groove fixedly provided below the gap 10 to receive the liquid. The lower end of the air chamber 2 can also be provided with a cone-like body to gather the liquid, and the bottom of the cone is directly welded to the drain pipe to guide the liquid to the outside of the vehicle. In addition, the other end of the drainage structure is connected to the outside of the vehicle. The specific position of the above-mentioned connection with the outside of the vehicle, that is, the setting position of the drainage outlet of the drainage structure, is not specifically limited in the embodiment of the utility model, and can be provided at the bottom or side of the vehicle, as long as the liquid in the air chamber 2 can be smoothly discharged to the outside of the vehicle body.

[0027] Exemplarily, the air outside the vehicle flows along Figure 1 The air enters the air conditioning outlet in the direction of the middle arrow. During this process, the air passes through the air chamber 2, and the wind speed changes from turbulent to gentle, and enters the air conditioning inlet 9 connected to the air conditioning outlet. The rainwater entrained in the air is discharged through the drainage structure.

[0028] By arranging an air chamber 2 in front of the air inlet 9 of the vehicle air conditioner and a drainage structure below the air chamber 2, when external air enters the air chamber 2 and then enters the air conditioner, rainwater or other liquids mixed in the air can flow to the drainage structure in the air chamber 2, thus realizing the filtration and impurity removal of the external air. Compared with the air-conditioning vehicles in the prior art, the air inlet structure of the vehicle in the embodiment of the present invention is simple in design.

[0029] As an alternative embodiment, as Figure 1 and Figure 4 shown, the drainage structure includes a drainage gap 10 and a diversion groove 11; the drainage gap 10 is arranged at the bottom end of the air chamber 2, and the drainage gap 10 is a gap 10 formed between the bent lower end of the air chamber bottom plate 3 and the vehicle front wall panel 5 for liquid to flow out.

[0030] The diversion groove 11 is fixedly arranged under the drainage gap 10 and one end is communicated with the outside of the vehicle.

[0031] In this embodiment, the bending of the lower end of the air chamber bottom plate 3 can be understood as forming a slope at the lower end of the air chamber 2, which is convenient for guiding the liquid in the air chamber 2 to flow to the gap 10 at the bottom of the air chamber 2. The specific angle of the bending of the lower end of the air chamber bottom plate 3 is not specifically limited in the embodiment of the present invention. In addition, the above-mentioned diversion groove is arranged to receive the liquid flowing out from the gap 10 at the bottom end of the air chamber 2 and drain it to the outside of the vehicle.

[0032] In this embodiment, the drainage structure with the drainage gap 10 and the diversion groove 11 arranged in cooperation at the bottom end of the air chamber 2 can effectively guide and drain the accumulated water in the air chamber 2 while preventing the liquid from entering the air inlet 9 of the air conditioner, preventing water retention, and reducing the influence of the humid environment on the equipment and materials.

[0033] Of course, in some alternative embodiments, other types of drainage structures can be adopted. For example, the diversion groove 11 can be replaced with a drain pipe directly welded to the bottom end of the air chamber 2. The bottom end of the air chamber 2 no longer adopts the form with a gap 10, but is set into a conical-like structure for converging the liquid in the air chamber 2, and the liquid is directly led out to the outside of the vehicle through the drain pipe; or a condenser can be arranged at the bottom end of the air chamber 2 to condense the water vapor in the air chamber 2 at the lower end, and the water vapor flows to the outside of the vehicle through the drain pipe or the drainage groove 11, etc.; adopting other types of drainage structures does not affect the realization of the basic functions of the vehicle in the embodiment of the present invention.

[0034] As an alternative embodiment, the vehicle further includes at least one baffle 4, and the at least one baffle 4 is fixedly arranged on the gas passage of the air chamber 2, and the shielding area of the baffle 4 is smaller than the cross-sectional area of the gas passage of the air chamber 2.

[0035] In this embodiment, the baffle 4 can be understood as an obstruction provided inside the air chamber 2 for the gas flow inside the air chamber 2, but it does not completely block the gas flow. The material type of the baffle 4 is not limited in the embodiments of the present utility model, and metals, composite materials, foam materials, etc. can be used. The number and size of the above-mentioned baffle 4 are also not limited in the embodiments of the present utility model, as long as it can form a certain obstruction and buffering effect on the gas flowing in the air chamber 2. In addition, the type of obstruction of the above-mentioned baffle 4 inside the air chamber 2 is not specifically limited in the present utility model. For example, a mesh or perforated baffle 4 can be embedded in the air chamber 2 passage, or one end of a sealed solid plate can be tightly connected to the air chamber 2 passage, and the other end can leave a gap for the gas in the air chamber 2 to flow through, etc.

[0036] By providing the baffle 4 on the gas passage of the air inlet air chamber 2 of the air conditioner, while reducing the wind speed and softening the incoming air, it can further block dust and impurities in the air, improve the air filtration effect, and improve the air intake quality of the air conditioner.

[0037] Of course, in some alternative embodiments, an air outlet regulator or a filter screen, etc. can also be used to replace the baffle 4 in this embodiment, and the effect of reducing the wind speed and softening the incoming air can also be achieved. If there is a protective structure, it can compensate for the weak protection area of the air inlet 9 of the air conditioner.

[0038] As an alternative embodiment, the at least one baffle 4 is arranged in a staggered tooth shape.

[0039] In this embodiment, reference can be made to Figure 2 , and the specific number of the baffle 4 forming the staggered tooth shape is not specifically limited in the embodiments of the present utility model. Utilizing the unique arrangement of the air inlet 9 of the air conditioner in a staggered tooth shape makes the incoming air softer. At the same time, the evenly distributed toothed baffle 4 can effectively rectify the air flow, make the air flowing into the air conditioner more stable, reduce the turbulence and non-uniformity of the air flow, and at the same time can effectively prevent the phenomenon of air flow backflow.

[0040] Of course, other layout forms of the baffle 4 can also be adopted. For example, a group of baffles 4 are arranged side by side opposite to each other, and by setting different angles or different lengths of the baffle 4, gaps 10 with different positions are formed between each group of baffles 4, so as to effectively disperse the air flow and reduce the direct impact feeling of the air flow; a baffle 4 with small holes can also be directly embedded in the air chamber 2 passage or other arrangement methods of the baffle 4, and the effect of softening the incoming air can also be achieved.

[0041] As an alternative embodiment, the incoming air opening direction of the natural air inlet 1 is consistent with the forward direction of the vehicle.

[0042] In this embodiment, the natural air inlet 1 is arranged outside the vehicle body. The air inlet is unobstructed, and the direction of the air inlet is consistent with the direction of vehicle advancement. During the vehicle's forward movement, the wind speed increases, enabling more effective intake of a large amount of air, meeting the air intake requirements of the air conditioner, enhancing power output. At the same time, the air inlet design consistent with the forward direction can better integrate with the overall appearance of the vehicle, improving the aesthetics of the vehicle as a whole.

[0043] Of course, setting the air inlet opening direction of the natural air inlet 1 in different directions, such as upward or downward, does not affect the realization of the basic functions of the vehicle in the embodiments of the present invention.

[0044] As an alternative embodiment, a plurality of small holes are provided on the air inlet opening surface of the natural air inlet 1.

[0045] In this embodiment, the above-mentioned natural air inlet 1 adopts a small hole and porous structure design, which can increase the contact area between air and the filter, thereby improving the air filtration efficiency, helping to remove dust, pollen, and other particulate matters in the air, improving air quality. At the same time, the design of small holes also helps to reduce the wind resistance of the natural air inlet 1.

[0046] Of course, the above-mentioned natural air inlet 1 can also use a filter mesh structure or an adjustable air inlet that can adjust the opening size and air flow direction according to needs. Adopting different air inlet types, as long as it can allow external air of the vehicle to enter the air chamber 2, it does not affect the realization of the basic functions of the vehicle in the embodiments of the present invention.

[0047] As an alternative embodiment, the vehicle further includes a bulletproof steel plate 7, which is welded on the air chamber bottom plate 3 and is arranged in parallel in front of the air conditioner air inlet 9.

[0048] The bulletproof steel plate 7 can provide additional protection for the vehicle, prevent external impacts and ballistic threats, enhance the safety of the vehicle in dangerous environments, and is particularly suitable for the safe transportation of vehicles in multiple scenarios.

[0049] Of course, other alternative materials such as high-strength plastics, steel fiber composites, tempered glass, or aluminum alloys can also be used according to specific requirements and usage scenarios, which can also resist ballistic impacts to a certain extent and provide a certain degree of protection for the air conditioner air inlet 9.

[0050] As an alternative embodiment, sealant is applied around the weld of the air chamber 2.

[0051] In this embodiment, sealant is applied around the weld of the air chamber 2, which can effectively fill the gap 10 between the welds, prevent air leakage, ensure the airtightness of the air chamber 2, prevent rainwater from entering the air conditioner air inlet 9, and can also reduce the wear and damage of the welds, thereby reducing the frequency of maintenance and repair.

[0052] Of course, waterproof coating can also be used to coat around the weld to form a protective film to prevent water penetration, or a self-adhesive sealing tape can be directly pasted around the weld, which can also provide a certain sealing effect.

[0053] As an alternative implementation, the weld around the air chamber 2 is coated with a polymer-based coating.

[0054] In this implementation, the above polymer-based coating has good anti-corrosion and sealing properties and is suitable for protecting the weld. Of course, other alternative materials such as polyurethane sealant or silicone sealant can also be used according to specific scenarios and application requirements, which can also effectively prevent water and air penetration.

[0055] As an alternative implementation, the material of the air chamber bottom plate 3 is thin ordinary steel plate.

[0056] In this implementation, the front baffle of the above air chamber 2 is made of thin ordinary steel plate, which is beneficial for weight reduction, and the thin ordinary steel plate has a lower cost compared to other materials (such as stainless steel or aluminum alloy), which helps to reduce the overall manufacturing and production costs and is suitable for mass production.

[0057] Of course, in other embodiments of the present utility model, the air chamber bottom plate 3 made of other materials can also be used, such as aluminum alloy, stainless steel or glass fiber reinforced plastic, etc. Using the air chamber bottom plate 3 made of different materials does not affect the realization of the basic functions of the vehicle in the embodiments of the present utility model.

[0058] In summary, in the embodiments of the present utility model, since the vehicle includes:

[0059] An air chamber 2, which is fixedly arranged in the vehicle engine compartment and is a sealed cavity formed by welding an air chamber bottom plate 3 parallel to the vehicle front bulkhead 5 and an L-shaped plate 8 perpendicular to the vehicle front bulkhead 5 on the vehicle front bulkhead 5;

[0060] An air-conditioning air inlet 9, which is opened on the vehicle front bulkhead 5, and the interior of the air chamber 2 is communicated with the vehicle air conditioner through the air-conditioning air inlet 9;

[0062] A drainage structure, which is fixedly arranged at the bottom end of the air chamber 2, one end is communicated with the bottom of the air chamber 2, and the other end is communicated with the outside of the vehicle.

[0063] By arranging an air chamber 2 in front of the air inlet 9 of the vehicle air conditioner and a drainage structure below the air chamber 2, when the external air enters the air chamber 2 and then enters the air conditioner, the rainwater or other liquids mixed in the air can flow to the drainage structure in the air chamber 2, thereby realizing the filtration and impurity removal of the external air. Compared with the vehicle air conditioners in the prior art, the air inlet structure of the vehicle air conditioner in the embodiment of the present utility model is simple in design.
