Description

Commercial car carpet, carpet heating system and vehicle Technical Field The invention belongs to the technical field of commercial vehicle heating, and particularly relates to a commercial vehicle carpet, a carpet heating system and a vehicle. Background With the continuous improvement of the living standard of the modern society, the requirements of commercial vehicle users on the thermal comfort in the cab are increasingly improved, the cab is used as the main movable space of the commercial vehicle drivers and passengers, the quality of the thermal environment directly influences the body feeling experience, the working efficiency and the rest quality of drivers and passengers, and especially under the low-temperature working condition in winter, the improvement of the thermal comfort in the cab becomes one of important stress points of commercial vehicle market competition. Currently, commercial vehicles are operated in winter, and heating in a cab is mainly realized by means of a vehicle-mounted air conditioning system, and warm air is blown into the cab through an air outlet arranged in an instrument panel area, so that temperature rise in the cab is realized. Under the parking working condition, the running air conditioner cannot continuously work, and the commercial vehicle is heated by an independent warm air heater arranged below the sleeper area, and the independent warm air heater blows warm air to the front area of the cab through an air outlet arranged on the sleeper baffle to maintain the basic temperature inside the cab. On the one hand, the warm air of the air conditioner under the driving working condition or the independent warm air heater under the parking working condition is blown through the air outlet, the problem that the coverage area of the warm air is smaller exists, the whole area of the cab cannot be heated uniformly, the whole temperature rising speed of the cab is slow, on the other hand, the heating effect of the heating mode on the main and auxiliary driving foot areas is extremely poor, and the warm air is difficult to effectively deliver because the foot areas are positioned at the bottom of the cab and far away from the air outlet, so that the temperature of the main and auxiliary driving foot areas is in a lower level for a long time, and uncomfortable symptoms such as foot cooling and limb stiffness are easy to occur to drivers and passengers. The commercial vehicle driver often faces the scenes of goods such as parking, long-distance parking rest and the like, under the scenes, the driver and the passenger are in the cab for a long time, the defects of the heating mode are further amplified, the thermal comfort of the cab is extremely poor, the rest quality of the driver and the passenger is seriously influenced, and the physical health and the follow-up driving safety of the driver and the passenger are possibly influenced if the driver and the passenger are in a low-temperature foot environment for a long time. Especially in the severe cold region of north or extremely cold operation scene, this problem is more prominent. Therefore, an independent heating system capable of heating the ground area of the cab of the commercial vehicle and realizing rapid foot temperature rise is developed, the defects in the prior art are overcome, the technical problem to be solved in the current commercial vehicle field is solved, and the independent heating system has important market application value and practical significance. Disclosure of Invention The invention aims to provide a commercial vehicle carpet, a carpet heating system and a vehicle, wherein an air guide channel is formed in a carpet main body and is communicated with an independent heating system, so that warm air can be quickly conducted to a main foot region and an auxiliary foot region from the surface of the carpet, a temperature sensor is arranged in the carpet region, automatic temperature control is realized, local overhigh temperature is avoided, the heating comfort of feet of passengers is improved, the structure is simple, the cost is low, the waste heat of the independent heating system is used for heating the ground of a cab, the problem that the main foot region and the auxiliary foot region are difficult to quickly heat when the commercial vehicle resides in winter is solved, and the purpose of energy conservation is realized. The specific scheme comprises the following steps: the utility model provides a commercial car carpet, includes carpet main part and carpet wind-guiding wind channel, and the carpet main part is multilayer structure, and carpet wind-guiding wind channel wears to locate between the top layer and the bottom of carpet main part along X to the interval, and carpet wind-guiding wind channel one end is arranged in being linked together with the heating wind channel that corresponds in the independent heating system, and its other end is arranged in being linked together with driver a
