A self-opening heat-contacting car steering wheel heating pad

Abstract

The invention discloses a self-opening heat-contacting automobile steering wheel heating pad, which belongs to the field of automobile steering wheel-related equipment. The invention realizes the inward extrusion of the self-opening heat-conducting ball through the driver's grip pressure on the soft cover, not only The position of the self-opening heat conduction ball is changed to release hot gas, and the shape of the self-opening heat conduction ball itself changes, so that the soft cover and the heat conductor are in direct contact, and combined with the dual heat conduction of the heat conductor and hot gas, the heat is effectively transferred to the The driver's hand is heated; when the driver's grip pressure disappears, the self-opening heat conduction ball rebounds and recovers its shape, effectively blocking the release of hot air and its own heat transfer, so the present invention realizes the protection of the driver's hand The required self-heating process effectively reduces heat loss.

Description

technical field [0001] The invention relates to the field of equipment related to automobile steering wheels, in particular to a self-opening heat-contact heating pad for automobile steering wheels. Background technique [0002] As the outdoor temperature drops in winter, it has gradually become a trend that the heating function of the steering wheel of a car has gradually become a trend. Now both high-end and low-end cars are beginning to develop electric heating steering wheels. This function can make the steering wheel warm in a short time in the cold season, so that the driver no longer feels cold and uncomfortable when holding the steering wheel, increases driving comfort, and reduces driving accidents caused by low temperature. [0003] However, this type of heating device has obvious disadvantages, that is, uneven heating, and it is easy to cause fire accidents due to uneven heating. Partial locations are extremely cold, which can easily affect the driver's feel and ...

[0003] However, this type of heating device has obvious disadvantages, that is, uneven heating, and it is easy to cause fire accidents due to uneven heating. Partial locations are extremely cold, which can easily affect the driver's feel and cause safety accidents

[0004] Most of the driver's grip areas are 3 o'clock and 9 o'clock on the steering wheel, and there are relatively few grips in other positions. One method is to heat these two areas alone, which is likely to cause uneven heating and cause fire accidents. The driver's hand is held in other positions, and switching between extremely hot and extremely cold can easily affect the driver's feel and cause safety accidents. Another method is to heat the steering wheel as a whole, but this will easily cause heat loss in other positions. and churn, costly
