[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0018] like Figure 1-3 As shown, the embodiment of the present application discloses a heatable windproof quilt, comprising a leg guard 10, a hand guard 20, a chest guard 30, a shoulder guard 40, a side guard 50 and a leg rest 60. The leg guard 10, the hand guard 20, the chest guard 30, the shoulder guard 40 and the side guard 50 are all three-layer structures arranged from the outside to the inside, namely, an outer waterproof layer 1, an inner thermal insulation layer 2 and an inner lining 3. The outer waterproof layer 1 is made of polyester taffeta waterproof fabric, which has strong waterproof performance and is not easy to be broken. It is located in the outermost layer of the windproof quilt and can effectively prevent rain and water vapor mixed in the cold air from wetting the quilt body. At the same time, it can effectively prevent cold wind from penetrating, playing the role of windproof and waterproof. The inner thermal insulation layer 2 is made of thickened thermal insulation cotton, which mainly plays the role of heat preservation. The inner lining 3 is made of arctic velvet fabric, which has the advantages of softness and skin-friendliness. It is arranged in the innermost layer and is in direct contact with the rider's body to improve the rider's comfort. The leg rest 60 is arranged on the inner side of the leg guard 10, and is located as a whole in the area enclosed by the leg guard 10, the chest guard 30, and the side guard 50. It does not need to be windproof or waterproof. Its main function is to rest on the rider's knees and thighs to keep the knees and thighs warm.
[0019] Specifically, the leg guard 10 is a sheet-like structure positioned in the front of the rider to protect against cold wind blowing in from the front. A chest guard 30 extends obliquely rearward from the top edge of the leg guard 10, shielding the rider's chest from wind and cold. Two side guards 50 are provided, extending rearward from either side of the leg guard 10. The leg guard 10, chest guard 30, and two side guards 50 form a semi-shell that is fixed in front of the rider to protect against cold wind while riding.
[0020] Two hand guards 20 are provided, one on each side of the top of the leg guard 10 and extending forward. The hand guards 20 are L-shaped cylindrical structures with two open ends. One end is connected to the leg guard 10 and has a corresponding notch in the leg guard 10 for the rider's hand to pass through. A tightening cord (not shown) is attached to the other end of the hand guard 20. When in use, the hand guard 20 is placed over the handlebars of the electric bike and tightened with the tightening cord to prevent air leakage. To prevent the rider's hands from freezing in cold weather, a heating layer 4 is installed between the inner insulation layer 2 and the inner lining layer 3 on the upper wall of the hand guard 20. Since the backs of the rider's hands contact the upper wall of the hand guard 20 when gripping the handlebars, the heating layer 4 is located between the inner insulation layer 2 and the inner lining layer 3 on the upper wall of the hand guard 20. This electrically heats the hand guard 20, keeping the rider's hands warm.
[0021] The shoulder guard 40 extends diagonally rearward from the top edge of the chest guard 30. The shoulder guard 40 rests entirely on the rider's shoulders, shielding them from wind and cold. Specifically, the shoulder guard 40 comprises a front shoulder portion 41, side shoulder portions 42, and a rear shoulder portion 43. The front shoulder portion 41 extends diagonally rearward from the top edge of the chest guard 30, connecting to the chest guard 30 on one side and extending to the rider's shoulders on the other. A circular notch is provided in the middle of the front shoulder portion 41, facing away from the chest guard 30, to protect the rider's neck.
[0022] Side shoulders 42 are provided downwardly on both sides of the front shoulder 41. The front sides of the two side shoulders 42 are fixedly connected to the corresponding side guards 50, so that the sides form a whole, improving stability and windproof effect. The rear shoulders 43 are provided on the rear sides of the side shoulders 42. The rear shoulders 43 and the side shoulders 42 are sewn together, so that the rear shoulders 43 can rotate relative to the side shoulders 42. The inner side surface of one rear shoulder 43 away from the side shoulder 42 is connected to the outer side surface of the other rear shoulder 43 away from the side shoulder 42 by Velcro. When in use, the front shoulder 41 is placed on the rider's shoulders, the two side shoulders 42 are located on both sides of the shoulders, and the two rear shoulders 43 are placed on the rider's back shoulders from both sides to the middle and connected by Velcro, thereby keeping the rider's entire shoulders warm and cold-proof.
[0023] A further configuration is that a heating layer 4 is provided between the inner insulation layer 2 and the inner layer 3 of the rear shoulder portion 43. The heating by the heating layer 4 enables the rider's rear shoulder to feel the heat while riding, thereby preventing the shoulder from getting cold.
[0024] Because the rider sits while riding, a triangular cavity is formed between the thigh and abdomen. The leg guard 10 and the chest guard 30 can only block the wind and keep the rider warm. However, in extremely cold weather, the thermal insulation effect of the leg guard 10 and the chest guard 30 is limited, and the rider can still feel the cold. Therefore, a leg rest 60 is provided on the inner side of the leg guard 10. The leg rest 60 is in the form of a sheet, and its upper side is sewn to the inner side of the leg guard 10, so that the leg rest 60 can be rotated along the sewing line. When riding, the leg rest 60 can be turned over and placed on the rider's thigh. Since the leg rest 60 is provided on the inner side, waterproof performance does not need to be considered. It is composed of thermal insulation cotton provided in the middle and flannel provided on both sides. In this way, both sides of the leg rest 60 can contact the rider, providing a comfortable contact experience. In order to ensure the warmth-keeping effect of the leg rest 60, a heating layer 4 is provided between the thermal insulation cotton and the flannel cloth adjacent to the leg guard 10. The heat generated by the heating layer 4 can directly act on the rider's thighs and knees, thereby achieving a better warmth-keeping effect.
[0025] Furthermore, a thermal insulation cotton cloth (not shown) is provided on the side of the leg rest 60 adjacent to the leg guard 10. The upper and lower edges of the thermal insulation cotton cloth are sewn together with the upper and lower edges of the flannel cloth on the side of the leg rest 60 adjacent to the leg guard 10, thereby forming a sleeve with both ends open in the horizontal direction on the side of the leg rest 60 adjacent to the leg guard 10. When a rider needs to carry a child while riding, the child can squat on the footboard of the electric vehicle, so that the child is covered by the windproof quilt. In cold weather, the child can put his or her hands into the sleeve formed between the leg rest 60 and the thermal insulation cotton cloth to warm their hands.
[0026] Furthermore, the heating layer 4 of the embodiment of the present application includes a tin film temperature-locking layer 401 and an electric heating wire layer 402 from the outside to the inside. The tin film temperature-locking layer 401 is arranged adjacent to the inner thermal insulation layer 2, so that the heat generated by the electric heating wire layer 402 can only be transferred to the inner layer 3 in one direction, thereby greatly improving the heating effect, effectively preventing part of the heat from being lost after being transferred to the inner thermal insulation layer 2, and greatly improving the thermal efficiency. The electric heating wire layer 402 includes a composite fiber heating wire sheet and an insulating film arranged on both the inside and outside sides, and the insulating film plays an electrical insulating role. Each electric heating wire layer 402 leads to a set of power lines, which are routed along the inner layer 3 to the bottom of the leg guard 10, integrated into a wiring harness, and then led out from the inner layer 3. The integrated wiring harness is connected to an inverter and a connector, and is connected to the electric vehicle power supply through the connector.
[0027] The operating principle of a heatable windshield blanket in the present embodiment is as follows: the hand guard 20 is put on the handlebar of the electric vehicle and fixed, and the power is turned on when in use. The heating layer 4 of the hand guard 20, the shoulder guard 40, and the leg rest 60 are energized and heated to provide heat for the rider's hands, shoulders and legs, so that the rider's hands, shoulders and legs are always in a warm state. When the rider's hands, shoulders and knees are very warm, the rider will not feel cold while riding, and will not have frozen hands, frozen legs or even catch a cold, thereby solving the problem of poor thermal insulation effect of traditional windshield blankets.
[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
