Description

Technical Field

[0001] The utility model relates to the technical field of rail transit seats, in particular to a lumbar support system with heating and ventilation functions for rail transit vehicles. Background Art

[0002] Rail transit vehicles, especially urban rail vehicles, are required to be equipped with wheelchair areas, and lumbar supports are installed in these areas for the convenience of passengers. When the wheelchair area is not occupied by a wheelchair, normal passengers can stand in this area to ride. To improve riding comfort, passengers can lean on the lumbar support, which saves effort and keeps the body stable. The lumbar support is mainly divided into two parts: the lumbar support surface and the connecting structure. The lumbar support surface allows passengers to lean on it and is generally supported by aluminum alloy or fiberglass. The back of the lumbar support surface is connected to the connecting structure, which is generally supported by a stainless steel pipe. It is used to support the lumbar support surface and fix the lumbar support to the side wall of the vehicle body.

[0003] Currently, wheelchair areas on rail transit vehicles are very common, and all are equipped with lumbar supports. However, existing wheelchair areas or lumbar supports have the following two major problems: First, during peak hours, when the subway is crowded, the heads and shoulders of wheelchair passengers are at the waist level of the standing crowd. There are generally no air conditioning vents at this height, so the cooling effect is weak in the summer, which generally causes disabled people to feel hot and even sweat. Second, when disabled people who are not in wheelchairs are riding the subway, they can lean on the lumbar support. The surface temperature of the lumbar support is lower in winter, but in the summer, after leaning for a long time, the contact area will sweat due to lack of ventilation. These problems occur on almost all subway lines and need to be solved urgently. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a lumbar support system with heating and ventilation functions for rail transit vehicles. The heating and ventilation functions of the lumbar support can be automatically controlled by the system, and a manual control function is provided on the lumbar support, which is convenient for passengers to adjust the temperature and air volume according to their body sensation.

[0005] The technical solutions provided by this utility model are as follows:

[0006] A lumbar support system with heating and ventilation functions for rail transit vehicles includes an air conditioner for ventilation according to input, a lumbar support, and a driver display screen. The lumbar support is provided with a temperature sensor, an air volume sensor, and a mode switching knob. The air conditioner includes a passenger compartment air conditioning unit for executing ventilation temperature and air volume instructions, and an air conditioning control panel for identifying the state of the mode switching switch and monitoring the state and data of the received temperature sensor and air volume sensor in real time. The driver display screen is effectively electrically connected to the lumbar support for displaying data input by the temperature sensor and the air volume sensor.

[0007] Preferably, the lumbar support is arranged on the side wall of the wheelchair area on the rail vehicle, a plurality of ventilation holes are provided on the front of the lumbar support, a heating resistance wire is provided inside the lumbar support, and an air inlet duct and an air outlet duct are respectively provided on the side and back of the lumbar support.

[0008] Preferably, the mode switching knob includes an automatic control mode and / or a manual control mode.

[0009] Preferably, when the mode switching knob includes a manual control mode, a temperature adjustment knob and a vent air volume knob are provided, and the temperature adjustment knob includes knob one for setting target temperature value one and knob two for setting target temperature value two, and the target temperature value one is not higher than the target temperature value two.

[0010] Preferably, the knob 1 and the knob 2 are arranged on different end surfaces of the lumbar support.

[0011] Preferably, when the mode switching knob includes the automatic control mode, option boxes for target temperature value 1, target temperature value 2, and air volume target value are provided on the driver display screen.

[0012] Preferably, the temperature sensor is arranged on the inner side of the lumbar support surface to monitor the temperature of the lumbar support surface and the air outlet temperature of the ventilation holes and transmit the data to the air conditioning control panel.

[0013] Preferably, the air volume sensor is arranged at the lumbar support air inlet duct to monitor the air supply volume of the two lumbar support air inlet ducts and transmit the data to the air conditioning control panel.

[0014] The control process and method of the lumbar support system with heating and ventilation functions for rail transit vehicles of the present invention are as follows:

[0015] When it is detected that the mode switch is in automatic control mode, the temperature of the lumbar support surface is monitored in real time and compared with the target temperature value set by the system. When it is lower than target temperature value 2, the lumbar support ventilation function is disabled. When it is lower than target temperature value 1, the resistance wire heating function is activated, and the power of the heating resistance wire is increased or decreased according to the difference between the real-time lumbar support surface temperature and target temperature value 1, to ensure that the lumbar support comfort is always at the value set by the system. When it is detected that the mode switch is in manual control mode, the automatic control process is automatically cut off. Different target temperature values 1 and 2 can be set in manual mode. When the surface temperature of the lumbar support is lower than target temperature value 1, the heating system is activated. The heating system will activate the resistance wire heating function and increase or decrease the power of the heating resistance wire according to the manual control requirements to ensure that the lumbar support comfort can be changed according to the passenger's own preferences at any time.

[0016] The utility model has the following advantages over the prior art:

[0017] The utility model relates to a lumbar support system with heating and ventilation functions for rail transit vehicles. The system links the vehicle's closed-loop control system with the lumbar support control system, and is provided with an automatic control mode and a manual control mode. The system can turn the heating and ventilation functions on, off, and adjust them according to the set temperature and air volume values. When the ambient temperature inside the vehicle is lower than the set target temperature value 1, the lumbar support surface has a surface heating function to ensure the comfort of the passenger when leaning at low temperatures. The lumbar support surface is provided with a plurality of small holes. When the ambient temperature inside the vehicle is higher than the set target temperature value 2, the lumbar support uses the connecting structure as an air duct to introduce the air from the air conditioner into the lumbar support, and uses the small holes to discharge the air, ensuring that the passenger does not sweat at the contact part of the support, or ensuring the comfort of disabled people in wheelchairs. The heating and ventilation functions of the lumbar support can be automatically controlled by the system, and a manual control function is provided on the lumbar support, which is convenient for passengers to adjust the temperature and air volume according to their body sensation.
