|Applicants:||YANCHENG ZHENYU TECHNOLOGY DEVELOPMENT CO., LTD.
|Title:||PTC CONSTANT-TEMPERATURE HEATED ELECTRICALLY ASSISTED BICYCLE WIND BLANKET|
A PTC heated electrically assisted bicycle wind blanket, capable of keeping warm at a constant temperature, comprising an upper wind blanket (1), protective sleeves (2), side wind blankets (3), a front wind blanket (4), permanent magnets (9) and a pocket (12). A cross-section of the wind blanket from outside to inside consists of a waterproof and windproof layer (5), a heat insulation layer (6), a PTC constant-temperature heating layer (7) and a lining (8); a lower hem location of a side wind blanket (3) is provided with two permanent magnets (9), and when a rider is riding, connecting the lower hems can increase warming effects of the wind blanket while also not causing difficulties for the rider dismounting; a pocket (12) is sewn into the wind blanket on a side close to a rider, used to place a mobile power source required for heating; two wires (11) lead out of the PTC constant-temperature heating layer (7) to acquire electrical energy from the mobile power source, hence a storage battery of the vehicle is not used as a power source, and no modification of an electric vehicle is required. The present bicycle wind blanket may be used to block wind and keep warm on an electrically assisted bicycle in winter; the wind blanket has a simple structure, is convenient to manufacture, has good warming effects and has strong usability.
