Detailed Description

Referring to fig. 1 to 5, an embodiment of the auxiliary air conditioning system 100 for a vehicle according to the present invention is adapted to be installed on a vehicle 900, the vehicle 900 includes a vehicle body 901 having a cabin space 902, and a vehicle air conditioning system 903 installed on the vehicle body 901, the vehicle air conditioning system 903 has a plurality of air conditioning outlets 905 and a plurality of internal circulation air inlets 904 communicating with the cabin space 902, and for convenience of description, only some of the air conditioning outlets 905 and the internal circulation air inlets 904 are shown in the drawings. The vehicle air conditioning system 903 can be controlled to switch between an in-vehicle circulation mode and an out-vehicle circulation mode, and when the in-vehicle circulation mode is switched, the air in the cabin space 902 is sucked through the internal circulation air inlet 904 for filtering, temperature adjustment and the like, and the treated air is discharged into the cabin space 902 through the air conditioner air outlet 905. In the present embodiment, the vehicle 900 shown in the drawings is a general sedan type vehicle as an example, but in practice, the vehicle 900 may be other types of vehicles, such as but not limited to a bus or a minibus.

The auxiliary air conditioning system 100 for a vehicle comprises a ventilation pipe 2 for being mounted on the vehicle body 901, a fan 31, a filter 32, a cooler 33, a heater 34 and an auxiliary damper 4 which are mounted on the ventilation pipe 2, an oxygen sensor 52, a timer 53 and a controller 51, wherein the controller 51 is in signal connection with the fan 31, the cooler 33, the heater 34, the auxiliary damper 4, the oxygen sensor 52 and the timer 53.

Referring to fig. 2, 3 and 4, the breather pipe 2 has an outer communicating end 21 for communicating with the outside, and a plurality of inner communicating ends 22 for communicating with the cabin space 902. In practice, the openings of the inner communication end 22 of the ventilation pipe 2 may be respectively disposed beside the air-conditioning exhaust port 905 (as shown in fig. 3), for example, beside the air-conditioning exhaust port 905 adjacent to the driver's seat and the front passenger seat, so that the air discharged into the cabin space 902 through the ventilation pipe 2 can be rapidly mixed with the air-conditioning gas discharged from the air-conditioning exhaust port 905 and dispersed in the cabin space 902. Alternatively, one or more openings of the internal communication end 22 of the snorkel 2 may be respectively disposed beside the internal circulation air inlet 904 of the vehicle air conditioning system 903 (as shown in fig. 4), so that the air discharged into the cabin space 902 through the snorkel 2 may be immediately sucked into the internal circulation air inlet 904 of the vehicle air conditioning system 903 for air conditioning, and then discharged through the air conditioning outlet 905. However, in practice, the position of the inner communication end 22 is not limited to the above-described configuration, and may be set to any position exposed to the vehicle interior space 902.

In the present embodiment, the breather pipe 2 has a plurality of branch pipe portions 20 each defining the inner communication end portion 22, but in other embodiments of the present invention, the breather pipe 2 may have only one inner communication end portion 22.

The fan 31, the filter 32, the cooler 33 and the heater 34 are arranged in the ventilation pipe 2 along the length direction of the ventilation pipe 2, and when the fan 31 is controlled to be activated, an airflow flowing from the outer communication end portion 21 to the inner communication end portion 22 is generated in the ventilation pipe 2, so that the outside air is injected into the cabin space 902 through the filter 32, the cooler 33 and the heater 34 in the ventilation pipe 2, that is, the air is pumped from the outside of the vehicle body 901 to the cabin space 902.

Referring to fig. 2, 4 and 5, the filter 32 filters the air passing through, for example, to remove dust and other harmful substances from the air. The cooler 33 is controlled by the controller 51 to cool the passing air. The heater 34 is controlled by the controller 51 to heat the air passing through. Since the filter 32 can filter air, the cooler 33 and the heater 34 can adjust the temperature of the air passing through the cooler according to the prior art and various types, and therefore, will not be described in detail.

The auxiliary damper 4 is installed at the external communication end 21 of the ventilation pipe 2, and is controlled by the controller 51 to be switched between a closed state for closing the external communication end 21 and an open state for allowing the external communication end 21 to communicate with the outside. Since the auxiliary damper 4 for openably closing the pipe port is of various types, such as but not limited to an electrically controlled valve, and is not the subject of the present invention, it will not be described in detail.

The oxygen sensor 52 is disposed in the cabin space 902 and is activated by the controller 51 to sense the oxygen content in the cabin space 902 and generate an oxygen sensing signal.

The controller 51 is used for signal connection with the vehicle air conditioning system 903, is built with a hypoxic ventilation mode and an automatic ventilation mode which can be switched on, and has a console 511 for being disposed in the cabin space 902 for operation. The console 511 is operable to perform switching activation of the cooler 33 and the heater 34, and switching between the hypoxic ventilation mode and the automatic ventilation mode.

When the controller 51 switches to the low-oxygen ventilation mode, it is triggered when the vehicle air conditioning system 903 starts the vehicle interior circulation mode, and controls the oxygen sensor 52 to start sensing the oxygen concentration of the cabin space 902, and controls the auxiliary damper 4 to switch to the open state when it is determined that the oxygen concentration corresponding to the oxygen sensing signal is lower than a low-oxygen threshold, and controls the timer 53 to start timing a ventilation time, during which the fan 31 is also controlled to start for drawing the outside air into the cabin space 902 through the ventilation pipe 2, so as to increase the oxygen concentration in the cabin space 902. The controller 51 controls the fan 31 to be turned off and the auxiliary damper 4 to be switched to the closed state after the ventilation time is timed out.

When the controller 51 switches to the automatic ventilation mode, the controller 51 is triggered when the vehicle air conditioning system 903 starts the vehicle circulation mode, and controls the timer 53 to start timing, and controls the auxiliary damper 4 to switch to the open state once every timing of a closed time, for example, every timing of 15 minutes or 30 minutes, and to maintain the open state for a ventilation time, for example, 5 minutes, during which the fan 31 is simultaneously controlled to start to suck the outside air into the cabin space 902 for increasing the oxygen concentration in the cabin space 902. When the ventilation time is timed out, the controller 51 controls to turn off the fan 31, controls the auxiliary damper 4 to switch to the closed state, and controls the timer 53 to count the off time again.

When the auxiliary air conditioning system 100 for a vehicle of the present invention is installed in the vehicle 900 for use, the controller 51 may be operated to switch the low-oxygen ventilation mode or the automatic ventilation mode, so that the auxiliary air conditioning system 100 for a vehicle is switched to the in-vehicle circulation mode for starting when the air conditioning system 903 of the vehicle 900 is switched to the in-vehicle circulation mode, and when the oxygen amount in the cabin space 902 is determined to be too low through analysis, the outside air is automatically sucked to increase the oxygen concentration, or the outside air is automatically sucked every time the off time is counted and the ventilation time is continued, so as to increase the oxygen concentration in the cabin space 902. By designing both of the ventilation modes, the oxygen concentration in the cabin space 902 can be increased at a proper time, which is helpful to reduce the problem of the driver's mind caused by the low oxygen.

In other embodiments of the present invention, the auxiliary damper 4 is not necessarily provided.

In addition, in the embodiment, the fan 31 is designed to be controlled to be activated to pump air into the cabin space 902 through the ventilation pipe 2, but in another embodiment of the present invention, the fan 31 may be designed to be controlled by the controller 51 to rotate in forward and reverse directions, wherein when the fan 31 is controlled to rotate in forward direction, air is pumped into the cabin space 902 through the ventilation pipe 2, and when the fan 31 is controlled to rotate in reverse direction, air flowing from the inner communication end 22 to the outer communication end 21 is generated in the ventilation pipe 2, that is, air is pumped out of the vehicle body 901 from the cabin space 902.

The controller 51 can control the design of the forward rotation and reverse rotation of the fan 31, and an air quality sensor (not shown) can be additionally installed in the cabin space 902, so that when the controller 51 analyzes that the sensing result of the air quality sensor is that the air quality is poor, for example, peculiar smell or smoke exists, the controller 31 is controlled to reverse rotation to discharge the air in the cabin space 902 to the outside. In addition, in other embodiments, it can be designed that when the user uses the remote controller to unlock the vehicle 900, the controller 51 is immediately powered on to control the fan 31 to rotate reversely for a predetermined time to remove the air staying in the cabin space 902 for a long time.

In another embodiment of the present invention, the controller 51 may further include a control key 512 disposed in the cabin space 902, the control key 512 may be used to electrically connect to an electrical system (not shown) of the vehicle 900, the controller 51 may be powered ON when the control key 512 is operated to be turned ON (ON), so that the console 511 may be used to operate a selection mode, and the fan 31 and/or the auxiliary damper 4 may be controlled to operate according to the sensing result of the oxygen sensor 52 or the timing result of the timer 53.

Since it is conventional and numerous that the main damper 72 can be controlled to close either the outer inlet end 711 or the inner inlet end 712 of the door, it will not be described in detail.

The blower 73 can be controlled by the controller 51' to generate an airflow in the main duct 71, which flows through the filter device 74 and the air conditioner 75 and is discharged into the cabin space 902 through the outlet end 713.
