[0025] In addition, if these terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "a plurality of" appears, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically limited.

For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically defined. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] In the present application, unless specifically defined otherwise, if there is a description of the first feature "on" or "under" the second feature and the like, it can mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are for illustrative purposes only and are not the only embodiment.

[0029] It should be noted that the dry and wet states of the driver's hands under different environmental conditions are different, and the hand conditions of the driver exist in both possible and impossible situations. For example, hand sweating and drying are possible situations, but if there is dust on the user's hands or other non-encountered conditions, the original function of the steering wheel disappears. In order to ensure the safety of driving, different hand conditions need to be dealt with. The function of the traditional car steering wheel is single and cannot deal with multiple hand conditions.

[0030] Referring to Figure 1 , Figure 1A schematic diagram of a steering wheel in an embodiment of the present application is shown, and the steering wheel provided by the embodiment of the present application comprises a steering wheel body 200, which is provided with an inner ring 201 and an outer ring 202 arranged outside the inner ring, and the steering wheel body is provided with a plurality of function parts 300 arranged adjacently or at intervals from the inner ring 201 to the outer ring 202.

[0031] The shape of the steering wheel body 200 can be, but is not limited to, a circle, and can also be a rectangle or other shapes. The number of function parts 300 from the inner ring to the outer ring is a plurality, and the arrangement position of each function part 300 can be set according to actual needs, and the function parts 300 can be arranged adjacently or at intervals.

[0032] Optionally, the plurality of function parts 300 comprises at least two of a protection part 301, a heating part 302, a ventilation part 303 and a health monitoring part 304, for example, the plurality of function parts 300 can comprise the protection part 301 and the heating part 302, can also comprise the protection part 301 and the ventilation part 303, and can also comprise the protection part 301, the heating part 302, the ventilation part 303 and the health monitoring part 304.

[0033] The protection part 301 can cope with different situations of the hand state, thereby improving the driving experience, enhancing the driving safety and protecting the cleanliness and appearance of the steering wheel, etc. For example, when the driver holds the steering wheel, hand slipping can occur due to sweating of the hands, and hand slipping can occur after holding the steering wheel for a long time, etc. The anti-slip setting can be performed by the protection part 301. For example, in order to avoid hand slipping in the case of sweating of the hands, the protection part 301 can be used for sweat absorption, and the protection part 301 can be used for oil absorption in the case of oil stains caused by sweating.

[0034] The heating part 302 is used for cold working conditions of the steering wheel, and the heating part 302 can be used for heating the steering wheel in order to ensure the safety of driving. The health monitoring part 304 can obtain physiological parameters (such as blood pressure, blood oxygen and heart rate, etc.) of the driver during driving, and report the collected parameters to a vehicle domain controller, so as to monitor the health of the driver.

[0035] The automobile steering wheel can detect the hand state at any position on the steering wheel, and different functional parts 300 can cope with the respective corresponding hand state, without the need to increase additional external accessories to cope with various hand states at any position, avoiding the application of only a single hand state and the application of only a specified position hand state.

When ventilation is needed, the air conditioning of the vehicle is triggered to send air, the electromagnetic valve is opened, and the air from the air conditioning pipeline of the vehicle is transmitted to the second annular cavity to ventilate the steering wheel of the vehicle. When ventilation is needed, the air conditioning of the vehicle is triggered to send air, the air is transmitted to the second annular cavity by the fan to ventilate the steering wheel of the vehicle, and the steering wheel ventilation function can keep the hands dry, reduce the influence of hand sweat on the steering wheel, and improve the comfort and safety of driving.

Further, the physiological parameters collected by the monitoring sensor in real time can be uploaded to the vehicle system for analysis, the vehicle system can intelligently track and feedback the physical and emotional state of the driver, and provide instant reminders and warnings when abnormal conditions occur, to improve driving safety. In addition, when the driver is detected to have a health risk, the system can notify through the mobile phone network communication module and send control information to the vehicle body control module to take appropriate safety measures to prevent risks caused by sudden health problems.

[0041] In addition, based on the health monitoring part 304, the health signs of the user are monitored in real time, and the corresponding ventilation and heating functions are automatically triggered to keep the user's hands at a dry and sweating intermediate point, so as not to be too dry and not enough friction, or too wet and not enough friction.
