Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a vehicle. Background Art

[0002] The air conditioning system on a traditional fuel vehicle generally includes a compressor, a condenser, a blower, an expansion valve and an evaporator. The compressor is installed on the engine and driven by the engine crankshaft belt; the condenser is installed behind the air intake grille on the front of the car for heat dissipation; the blower, expansion valve and evaporator are installed under the car dashboard. The high-temperature, high-pressure refrigerant coming out of the compressor enters the condenser through a high-pressure hose. Since the temperature outside the car is lower than the temperature of the refrigerant entering the condenser, with the help of the condensing fan. A large amount of heat of the refrigerant in the condenser is taken away by the air outside the car, so that the high-temperature, high-pressure gas is condensed into a high-temperature, high-pressure liquid. When this high-temperature, high-pressure liquid flows through the throttling expansion valve, due to the throttling effect, the volume suddenly increases and the pressure drops, and it becomes a low-temperature, low-pressure mist (liquid) that enters the evaporator, vaporizes under a constant pressure, and is transported to the cockpit and passenger compartment through the blower. Since the temperature of the refrigerant when it vaporizes in the tube is lower than the circulating air in the car outside the evaporator tube, it can automatically absorb heat from the air outside the tube, thereby lowering the temperature of the air flowing through the evaporator, producing a cooling effect. The vaporized refrigerant is sucked and compressed by the compressor, becoming a high-temperature, high-pressure gas, and then sent to the condenser through a high-pressure hose, thus completing a thermal cycle of the refrigeration system.

[0003] However, the major equipment in the above-mentioned air-conditioning system is relatively scattered, the pipeline distribution is complex, and the blower, expansion valve and evaporator are very close to the cockpit, so they will generate loud noise when working, affecting the NVH performance of the vehicle.

[0004] In new energy vehicles, since there is no engine, it is possible to implement a highly integrated vehicle air-conditioning system. Summary of the invention

[0005] The present disclosure provides a vehicle to solve at least part of the problems in the related art.

[0006] According to a first aspect of the present disclosure, a vehicle is proposed, comprising a vehicle body and a hood, a cabin, a cockpit and an air-conditioning system arranged on the vehicle body; the cabin is located between the hood and the vehicle body; the air-conditioning system is located in the cabin and comprises a shell, an exhaust passage and a water receiving structure; the shell comprises an upper surface facing the hood; the exhaust passage comprises an air inlet connected to the cockpit and an air outlet arranged on the upper surface; the water receiving structure is arranged on the upper surface, and condensed water generated after the gas discharged through the air outlet contacts the hood at least partially falls into the water receiving structure.

[0007] Optionally, the vehicle body includes a front end and a rear end along its length direction; the hood includes a first plate located above the air outlet; the first plate gradually tilts downward in a direction from the rear end to the front end.

[0008] Optionally, the water receiving structure and the air outlet are arranged in sequence along the direction from the front end to the rear end.

[0009] Optionally, the front cover also includes a second plate and a connecting portion connected between the first plate and the second plate; the connecting portion is located above the water receiving structure; along the direction from the rear end to the front end, the second plate is horizontal or gradually tilted upward.

[0010] Optionally, the water receiving structure includes a trough body extending along the width direction of the vehicle body.

[0011] Optionally, the water receiving structure also includes a water outlet; the water outlet is arranged at one end of the trough body.

[0012] Optionally, along the direction from the rear end to the front end, the trough body sequentially includes a first side wall and a second side wall that are arranged opposite to each other;

[0013] The water receiving structure further includes a first baffle and a second baffle protruding from the upper surface; the first baffle is disposed on the first side wall, and the second baffle is disposed on the second side wall.

[0014] Optionally, the second baffle is inclined in a direction approaching the first baffle.

[0015] Optionally, the air conditioning system further comprises an evaporator core, a drain port and a water receiving hole; the water receiving hole is arranged on the upper surface; the evaporator core is located in the shell; and is located below the water receiving hole;

[0016] The condensed water generated after the gas discharged through the air outlet contacts the hood at least partially falls into the evaporator core through the water receiving hole;

[0017] The drain port is connected to the evaporator core to drain the condensed water in the evaporator core.

[0018] Optionally, the air conditioning system includes two water receiving holes; the two water receiving holes are respectively located at the front and rear sides of the water receiving structure.

[0019] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0020] In the present disclosure, the air outlet of the exhaust duct is arranged on the upper surface of the shell. This is because the distance between the upper surface of the shell and the hood is small. After the cold air is discharged from the air outlet, it can still remain in a gathered state within a short distance, so that the contact area between the cold air and the hood is controlled within a smaller range. In other words, the area where condensed water is generated is determined and is almost the same size as the air outlet, thereby facilitating the control of condensed water. When condensed water is generated and accumulates, it will drip due to gravity. At this time, the dripping condensed water is received and restrained by the water receiving structure arranged on the upper surface of the shell, thereby preventing the condensed water from moving arbitrarily on the shell and corroding the wires to cause a short circuit.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0030] The present disclosure provides a new energy vehicle that no longer has an engine. The new energy vehicle includes a vehicle body (not shown in the figure) and a hood 1, a cabin 2, a cockpit (not shown in the figure) and an air-conditioning system 3 arranged on the vehicle body. The cabin 2 is located between the hood 1 and the vehicle body. Among them, the air-conditioning system 3 is highly integrated and is located in the cabin 2. Of course, in other embodiments, the vehicle can also be a traditional fuel vehicle, as long as its air-conditioning system 3 is highly integrated and arranged in the cabin 2, and the present disclosure does not limit this.

[0031] The air conditioning system 3 includes a compressor, a condenser (not shown in the figure), a blower (not shown in the figure), an expansion valve (not shown in the figure) and an evaporator (not shown in the figure). Among them, the pipeline distribution and operation principle between the compressor, condenser, blower, expansion valve and evaporator are no different from the existing air conditioning system 3, and will not be described in detail here. The high degree of integration of the air conditioning system 3 means that the compressor, condenser, blower, expansion valve and evaporator are installed in a centralized manner, thereby reducing the space occupied by the air conditioning system 3, so that the air conditioning system 3 can be placed in the cabin 2. Compared with the blower, expansion valve and evaporator in the traditional fuel vehicle are arranged under the car dashboard, it can greatly reduce the noise impact of the blower when working and improve the NVH performance of the vehicle.

[0032] It should be noted that the compressor in a traditional fuel vehicle is located at the engine, that is, it is close to the chassis of the car. When the compressor discharges cold air out of the car, even if the cold air encounters metal parts or plastic parts at the outlet and forms condensed water on their surface, since there is no other equipment of the air-conditioning system 3 near the compressor, the condensed water will not affect the air-conditioning system 3. At the same time, since the compressor is located at the chassis of the car, the condensed water can also be discharged quickly. In the present disclosure, since the air-conditioning system 3 is located in the cabin 2, the wires in the cabin 2 are densely distributed. In this way, when the discharged cold air encounters condensed water formed by metal parts or plastic parts, it is easy to drip on other equipment of the air-conditioning system 3, causing corrosion of the equipment. In more serious cases, if the condensed water in the cabin 2 is not discharged through the drainage channel, it is easy to accumulate, thereby corroding the wires and causing a short circuit. Therefore, in some embodiments, such as Figure 1-3 As shown, the air conditioning system 3 includes a housing 30, an exhaust passage and a water receiving structure 31. The housing 30 includes an upper surface 300 facing the hood 1. The exhaust passage includes an air inlet connected to the cockpit and an air outlet 32 ​​arranged on the upper surface 300. The water receiving structure 31 is arranged on the upper surface 300, and the condensed water generated after the gas discharged through the air outlet 32 ​​contacts the hood 1 falls into the water receiving structure 31 at least partially. Among them, the housing 30 refers to the housing 30 of the compressor.

[0033] In the present disclosure, the air outlet 32 ​​of the exhaust channel is set on the upper surface 300 of the shell 30. Considering that the distance between the upper surface 300 of the shell 30 and the front cover 1 is small, the cold air can still maintain a gathered state within a short distance after being discharged from the air outlet 32, so that the contact area between the cold air and the front cover 1 is controlled within a smaller range. In other words, the area where condensed water is generated is determined and is about the same size as the air outlet 32, so that it is convenient to control condensed water. When condensed water is generated and accumulates more, the condensed water will drip due to gravity. At this time, the water receiving structure 31 set on the upper surface 300 of the shell 30 receives and restrains the dripping condensed water, so as to prevent the condensed water from moving randomly on the shell 30 and corroding the wires to cause a short circuit.

[0034] Continue to refer Figure 1 The vehicle body includes a front end and a rear end along its length direction. The hood 1 includes a first plate 10 located above the air outlet 32. The first plate 10 gradually tilts downward in the direction from the rear end to the front end. When the condensed water is just formed, the water droplets of the condensed water are small, and the condensed water mainly adheres to the surface of the first plate 10. At the same time, since the first plate 10 gradually tilts downward in the direction from the rear end to the front end, the condensed water rolls forward along the first plate 10 under the action of gravity, that is, the first plate 10 can guide the condensed water.

[0035] As an optional embodiment, the first plate 10 includes a lower surface for contacting the gas. The lower surface includes a first surface and a second surface and a third surface respectively arranged on both sides of the first surface. The first surface, the second surface and the third surface all extend along the length direction of the vehicle and gradually tilt downward. Among them, the first surface is lower than the second surface and the third surface. Through such a configuration, the condensed water on the second surface and the third surface will gradually flow to the first surface during the process of moving forward, thereby further reducing the falling area of ​​the condensed water, so that the water receiving structure 31 can more easily receive the dripping condensed water.

[0036] As an optional embodiment, the hood 1 also includes a second plate 11 and a connecting portion 12 connected between the first plate 10 and the second plate 11. The connecting portion 12 is located above the water receiving structure 31. In the direction from the rear end to the front end, the second plate 11 is horizontal or gradually tilted upward. Through the second plate 11 and the connecting portion 12. The condensed water moving from the first plate 10 is greatly deflected in the displacement direction when flowing through the connecting portion 12 and the second plate 11, and can then fall off the first plate 10. In other words, the condensed water will basically fall from the front edge of the first surface. In this way, the water receiving structure 31 is arranged just below the front edge of the first surface to receive the dripping condensed water.

[0037] As an optional embodiment, the water receiving structure 31 and the air outlet 32 ​​are arranged in sequence in the direction from the front end to the rear end. In this way, the water receiving structure 31 cooperates with the first plate 10, so that the condensed water formed after the cold air out of the air outlet 32 ​​contacts the first plate 10 can drip into the water receiving structure 31.

[0038] In some embodiments, the water receiving structure 31 includes a groove 310 extending in the width direction of the vehicle body. Referring to the above, it can be seen that the falling area of ​​condensed water is the front edge of the first surface, and the front edge of the first surface is a line extending in the width direction of the vehicle. Therefore, the water receiving structure 31 includes a groove 310 extending in the width direction of the vehicle body, which can be adapted to the front edge of the first surface, so as to have a larger effective water receiving area, thereby preventing condensed water from dripping outside the water receiving structure 31.

[0039] As an optional embodiment, the projection of the front edge of the first surface on the trough body 310 in the vertical direction is the central axis of the trough body 310. In this way, the trough body 310 is symmetrically distributed along the front edge of the first surface, which can have a larger effective water receiving area, thereby preventing condensed water from dripping outside the water receiving structure 31.

[0040] As an optional embodiment, the water receiving structure 31 also includes a water outlet 313. The water outlet 313 is arranged at one end of the tank body 310. When the condensed water in the tank body 310 accumulates to a certain extent, the condensed water can be discharged to avoid excessive water accumulation in the tank body 310. Among them, the water outlet 313 can be connected to the drainage pipe, so that the condensed water in the tank body 310 is directly discharged outside the cabin body 2 through the drainage pipe. The water outlet 313 can also be connected to the side wall of the shell 30, that is, the condensed water flows along the side wall of the shell 30 to the bottom of the cabin body 2, thereby preventing the condensed water from flowing into the equipment through the gap between the shells 30 and corroding the wires.

[0041] Considering that the vehicle may decelerate, accelerate, turn, and other situations during driving, when the condensed water in the tank body 310 is collected to a certain extent, the condensed water in the tank body 310 may flow and fluctuate due to the above situation, or even spill out of the tank body 310. Therefore, in some embodiments, along the direction from the rear end to the front end, the tank body 310 includes a first side wall and a second side wall arranged opposite to each other in sequence. The water receiving structure 31 also includes a first baffle 311 and a second baffle 312 protruding from the upper surface 300. The first baffle 311 is arranged on the first side wall, and the second baffle 312 is arranged on the second side wall. In this way, by setting the first baffle 311 and the second baffle 312, the above situation can be effectively avoided. In addition, the first baffle 311 and the second baffle 312 are equivalent to increasing the height of the tank body 310 in disguised form, that is, shortening the distance between the tank body 310 and the first sheet metal, so that the condensed water on the first sheet metal can drip into the tank body 310 more easily.

[0042] As an optional implementation, the second baffle 312 is inclined in a direction close to the first baffle 311. In this way, it is possible to more effectively prevent the water in the tank body 310 from being splashed out.

[0043] As an optional implementation, the first baffle 311 is inclined in a direction close to the second baffle 312. In this way, it is possible to more effectively prevent the water in the tank body 310 from being splashed out.

[0044] Considering that the vehicle may experience various situations such as deceleration, acceleration, and turning during driving, and when this situation occurs simultaneously with the dripping of condensed water. The dripping condensed water will be greatly deflected, that is, it is very likely to cause the condensed water to drip outside the water receiving structure 31, that is, the trough body 310. Therefore, in some embodiments, the air-conditioning system 3 also includes an evaporator core 33, a drain port 34, and a water receiving hole. The water receiving hole is provided on the upper surface 300. The evaporator core 33 is located in the shell 30. And it is located below the water receiving hole. The condensed water generated after the gas discharged through the air outlet 32 ​​contacts the hood 1 falls into the evaporator core 33 through the water receiving hole at least in part. The drain port 34 is connected to the evaporator core 33 to discharge the condensed water in the evaporator core 33. Through such an arrangement, the air-conditioning system 3 cleverly utilizes its own evaporator core 33 and drain port 34, so that the condensed water dripping outside the trough body 310 falls into the evaporator core 33, and the condensed water is discharged by utilizing the drainage pipe of the evaporator core 33 itself, thereby cooperating with the water receiving structure 31 to ensure that the condensed water on the hood 1 can be completely discharged.

[0045] As an optional embodiment, the air conditioning system 3 includes two water receiving holes. The two water receiving holes are respectively located on the front and rear sides of the water receiving structure 31. When the vehicle decelerates, the dripping condensed water will fall in front of the water receiving structure 31, and when the condensed water moves back and forth on the upper surface 300, it will fall into the evaporator core 33 through the water receiving hole in front of the water receiving structure 31. Similarly, when the vehicle accelerates, the dripping condensed water will fall behind the water receiving structure 31, and fall into the evaporator core 33 through the water receiving hole behind the water receiving structure 31, thereby ensuring that most of the condensed water dripping from the hood 1 is received by the water receiving structure 31, i.e., the trough 310, and the remaining small part can fall into the evaporator core 33 from the water receiving hole.
