[0028] The following further describes the present utility model in detail with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0029] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0031] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0032] In the prior art, due to the relatively harsh working environment of mining dump trucks, they are easily attached with dust and need to be cleaned in time. The air compressors of existing driverless mining dump trucks are only used for purging radars, resulting in the need for additional air sources for other air-using structures (such as air seats and air horns) of driverless mining dump trucks to operate.

[0033] Therefore, the present utility model provides an auxiliary air-using system for vehicles. As Figure 1 shown, the auxiliary air-using system for vehicles includes an air compressor 1, a gas storage tank 2, a gas distribution valve 4, a purging pipe 5 and a switch valve 6. The air compressor 1, the gas storage tank 2, the gas distribution valve 4 and the switch valve 6 are sequentially connected through pipelines. Among them, the air compressor 1 is an air compressor, which is used to compress air and transport it into the gas storage tank 2. The gas storage tank 2 is used to store gas. In this way, when any air-using structure operates, the air compressor preferentially uses the compressed air in the gas storage tank 2 to operate. When the air pressure in the gas storage tank 2 is lower than the minimum preset air pressure, the air compressor operates to supply gas to the gas storage tank 2. The purging pipe 5 is communicated with the outlet of the switch valve 6. The gas distribution valve 4 has one inlet and multiple working outlets. The inlet of the switch valve 6 is communicated with one of the working outlets of the gas distribution valve 4, and other air-using structures can be communicated with other working outlets. The inlet and multiple working outlets of the gas distribution valve 4 are all communicated. In this way, when the purging pipe 5 purges the radar, other air-using structures can also obtain compressed air to operate normally. In this embodiment, by setting the gas distribution valve 4, the working requirements of radar purging and other air-using structures can be met, and the utilization rate of the air compressor 1 and the gas storage tank 2 is further improved. Since the radar purging and other air-using structures share the air compressor 1 and the gas storage tank 2, the additional setting of the air compressor 1 and the gas storage tank 2 is also eliminated.

[0034] It should be noted that the number of switch valves 6 is limited according to the number of radars. For example, if the radar includes two front radars and one rear radar, the number of switch valves 6 is three, so that each front radar and rear radar has a corresponding switch valve 6 for purging operations.

[0035] In some embodiments, the auxiliary air-using system for vehicles further includes a pressure limiting valve 3. The inlet of the pressure limiting valve 3 is communicated with the outlet of the gas storage tank 2, and the outlet of the pressure limiting valve 3 is communicated with the inlet of the gas distribution valve 4. The setting of the pressure limiting valve 3 can be used to limit the pressure of the compressed gas flowing out of the gas storage tank 2 to avoid damage to air-using structures (such as air seats, air horns 400, etc.) due to excessive gas pressure.

[0036] In some embodiments, the auxiliary air system for the vehicle further includes a cooling structure for cooling the compressed air. The inlet of the cooling structure is communicated with the outlet of the air compressor 1, and the outlet of the cooling structure is communicated with the inlet of the air storage tank 2. The air compressed by the air compressor 1 is a high-temperature and high-pressure gas. After passing through the cooling structure, the temperature decreases. In this way, the gas entering the air storage tank 2 is a low-temperature and high-pressure gas, avoiding explosion caused by too high temperature of the gas entering the air storage tank 2.

[0037] Specifically, as Figures 1-3 shown, the cooling structure includes a spiral tube 7. One end of the spiral tube 7 is communicated with the outlet of the air compressor 1, and the other end is communicated with the inlet of the air storage tank 2. The spiral tube 7 is formed by spirally arranging steel pipes. Here, a specific shape of the steel pipe is provided. As long as it can realize the cooling pipeline for compressed gas, it is within the protection scope. The spiral setting of the spiral tube 7 can make the overall length of the steel pipe longer, increase the flow path of the compressed air, and thus improve the cooling capacity of the steel pipe.

[0038] In some embodiments, the cooling structure further includes a condenser, which is respectively communicated with the spiral tube 7 and the air compressor 1, or the condenser is respectively connected with the spiral tube 7 and the air storage tank 2. The setting of the condenser can double-cool the compressed air and further reduce the temperature of the compressed air.

[0039] In some embodiments, the auxiliary air system for the vehicle further includes a dryer 8 for drying the compressed air. The inlet of the dryer 8 is communicated with the outlet of the air compressor 1, and the outlet of the dryer 8 is communicated with the inlet of the air storage tank 2.

[0040] The auxiliary air system for the vehicle further includes a first shunt valve. The inlet of the first shunt valve is communicated with one of the working outlets of the air distribution valve 4. The first shunt valve has at least two outlets, and each outlet of the first shunt valve is connected with a switching valve 6. The setting of the first shunt valve is used to increase the diversity of the air-using structures connected to the air distribution valve 4, and thus meet the air-using requirements of more air-using structures. Since the radar includes at least two front radars 200 and one rear radar 300, the two front radars 200 are arranged on the front end face of the vehicle frame 100, and the rear radar 300 is arranged on the rear end face of the vehicle frame 100. Therefore, one of the outlets of the first shunt valve is also connected with the inlet of a second shunt valve. The two outlets of the second shunt valve can be respectively connected with the purge pipes 5 for purging the two front radars 200, and the other outlet of the first shunt valve is directly connected with the purge pipe 5 for purging the rear radar 300.

[0041] In some embodiments, the auxiliary air system for the vehicle further includes an air filter 9. The outlet of the air filter 9 is communicated with the inlet of the air compressor 1. The air filter 9 is used to filter out impurities in the air, avoid the internal structure of the air compressor 1 from being worn by the impurities entering the air compressor 1, and in addition, it can also avoid the dust and impurities in the air from being sprayed on the radar and causing secondary shielding to the radar.

[0042] In some embodiments, the auxiliary air supply system for vehicles further includes a two-way solenoid valve 10 for supplying gas to the axle. The inlet of the two-way solenoid valve 10 is communicated with the inlet or the working outlet of the air distribution valve 4. The two-way solenoid valve 10 and the air distribution valve 4 are integrated into an integral valve, that is, the solenoid valve and the air distribution valve 4 share the same valve block. Such an arrangement can reduce the clutter of the air circuit layout and improve the neatness of the auxiliary air supply system for vehicles.

[0043] The present utility model also provides a vehicle, as Figure 1 and Figure 4 shown. The vehicle includes a vehicle frame 100, an air horn 400, an air seat, and the auxiliary air supply system for vehicles provided by the embodiments of the present utility model. The air horn 400 and the air seat are respectively communicated with the working outlets of the air distribution valve 4. Since the above-mentioned auxiliary air supply system for vehicles is included, the air distribution valve 4 has one inlet and multiple working outlets. The inlet of the switching valve 6 is communicated with one of the working outlets of the air distribution valve 4, while other air-using structures can be communicated with other working outlets. The inlet and the multiple working outlets of the air distribution valve 4 are all communicated. In this way, when the purging pipe 5 purges the radar, other air-using structures can also obtain compressed air to work normally. In this embodiment, by providing the air distribution valve 4, the working needs of radar purging and other air-using structures can be met, further improving the utilization rate of the air compressor 1 and the gas storage tank 2. Since the radar purging and other air-using structures share the air compressor 1 and the gas storage tank 2, the additional setting of the air compressor 1 and the gas storage tank 2 is also eliminated.

[0044] For example, the vehicle is a mine-use driverless dump truck.

[0045] Due to the inclusion of the above-mentioned auxiliary air supply system for vehicles, the vehicle of the embodiment of the present utility model has all the advantages and beneficial effects of the above embodiments, which will not be elaborated here.

[0046] In addition, the above is only the preferred embodiment of the present utility model and the applied technical principle. Those skilled in the art will understand that the present utility model is not limited to the specific embodiments described here. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present utility model. Therefore, although the present utility model has been described in more detail through the above embodiments, the present utility model is not limited to the above embodiments. Without departing from the concept of the present utility model, more other equivalent embodiments can be included, and the scope of the present utility model is determined by the scope of the appended claims.
