[0016] See also Figures 1-4 The utility model provides the following technical solution: it includes a solar energy storage panel 1, a heating plate 3, a connecting block 31 and a connecting seat 41, and is characterized in that: a base frame 2 is provided on the bottom of both sides of the solar energy storage panel 1, the heating plate 3 is fixedly connected to the inner side of the base frame 2, and the connecting block 31 is fixedly connected to the top of the heating plate 3, a plurality of return springs 32 are provided on the top of the heating plate 3, and a movable plate 4 is provided at the end of the return spring 32 away from the heating plate 3, and the connecting seat 41 is fixedly connected to the bottom of the movable plate 4, and wires 11 are provided on both sides of the solar energy storage panel 1, and the ends of the two wires 11 away from the solar energy storage panel 1 are respectively fixedly connected to the two connecting seats 41, and a protective cover 5 is provided on the outside of the movable plate 4.

[0017] In this embodiment, it includes a solar energy storage panel 1, a heating panel 3, a connecting block 31 and a connecting seat 41. The solar energy storage panel 1 includes a solar panel and a power storage processor. Therefore, when the solar energy storage panel 1 is located outdoors, it can convert the absorbed solar thermal radiation energy into electrical energy and store it. The connecting seat 41 and the connecting block 31 can be connected. When the connecting seat 41 and the connecting block 31 are connected, the solar energy storage panel 1 can supply power to the heating panel 3 to increase the temperature of the heating panel 3. Since the battery of the electric vehicle is located in the battery compartment at the bottom of the pedal, by fixing the heating panel 3 to the top of the pedal, the heating panel 3 can transfer heat to the battery compartment through the pedal when the temperature rises, thereby avoiding the battery from being too cold in winter due to excessive cold weather. 2 and the bottom of the base frame 2 is flush with the bottom of the solar energy storage panel 1. The heating plate 3 is fixedly connected to the inner side of the base frame 2, and the bottom of the heating plate 3 is flush with the bottom of the solar energy storage panel 1 and the base frame 2. By fixing the base frame 2 on the foot pedal, the heating plate 3 can be attached to the top of the foot pedal, so that when the temperature of the heating plate 3 rises, the foot pedal can transfer heat. The connecting block 31 is fixedly connected to the top of the heating plate 3. The top is provided with several return springs 32, and the return springs 32 are all located at the corners of the heating plate 3. A movable plate 4 is provided at one end of the return spring 32 away from the heating plate 3. The movable plate 4 matches the size of the heating plate 3. Through the connection of the return spring 32, the movable plate 4 can bounce upward and reset after falling. The connecting seat 41 is fixedly connected to the bottom of the movable plate 4. When the rider's foot steps on the movable plate 4, the foot will exert downward pressure on the movable plate 4, causing the connecting seat 41 to move downward to connect with the connecting block 31, so that the heating plate 3 is energized, and it can provide heat to the battery compartment during riding. When the riding is completed, the pressure above the movable plate 4 disappears, and the movable plate 4 can be moved upward by the return spring 32, and the connection The seat 41 will be separated from the connecting block 31, and the temperature of the heating plate 3 will gradually drop. Wires 11 are provided on both sides of the solar energy storage panel 1. The ends of the two wires 11 away from the solar energy storage panel 1 are fixedly connected to the two connecting seats 41 respectively. Through the connection of the wires 11, the solar energy storage panel 1 can be energized with the connecting seat 41. A protective cover 5 is provided on the outside of the movable panel 4. The protective cover 5 can protect the structure between the heating plate 3 and the movable panel 4 to avoid damage caused by long-term exposure to the outside. The protective cover 5 is made of soft material. When the movable panel 4 is raised or lowered, the protective cover 5 will be deformed accordingly. The gravity of the rider's feet can apply downward pressure to the movable panel 4, so that the connecting seat 41 and the connecting block 31 are connected during riding.The temperature of the heating plate 3 will rise, and through the conduction of heat from the pedal, the temperature of the battery compartment at the bottom of the pedal will rise, thus providing heat to the battery compartment during riding, thus preventing the battery from running at too low a temperature in winter due to excessive cold weather, which will lead to performance degradation and shortening of service life. At the same time, it can also protect the pedals of the electric vehicle and prevent the pedals from peeling or being damaged due to long-term pedaling.

[0018] One side of the two heating plates 3 is fixedly connected to the solar energy storage panel 1, and the base frame 2, heating plates 3 and movable plates 4 on both sides of the solar energy storage panel 1 are symmetrical to each other; since the solar energy storage panel 1 is located in the middle position, it is not easy for cyclists to step on the solar energy storage panel 1.

[0019] The position of the connecting seat 41 corresponds to that of the connecting block 31, and the wire 11 is located between the heating plate 3 and the wire 11; the size of the wire 11 is smaller than the thickness of the connecting seat 41 and the connecting block 31, therefore, when the connecting seat 41 is connected to the connecting block 31, the movable plate 4 and the heating plate 3 will not squeeze the wire 11.

[0020] A connecting plate 21 is provided on the side of the base frame 2 away from the solar energy storage panel 1, and an adhesive layer 211 is provided on the bottom of the connecting plate 21; by sticking the adhesive layer 211 on the pedal of the electric vehicle, the heating plate 3 can be fixed on the top of the pedal.

[0021] The edge of the protective cover 5 is fixedly connected to the solar energy storage panel 1 and the base frame 2, and a pedal 51 is provided on the top of the protective cover 5; when the rider's two feet step on the two pedals 51 respectively, the movable board 4 can be moved downward.

[0022] The working principle and usage process of the present invention are as follows: when riding, the rider's two feet are respectively placed on the two pedals 51, and the gravity of the feet can apply downward pressure to the pedals 51, which will cause the position of the movable plate 4 to drop. When the connecting seat 41 moves down to connect with the connecting block 31, the solar energy storage panel 1 can supply power to the heating plate 3, thereby increasing the temperature of the heating plate 3. Then, through conduction through the pedals, the temperature of the battery compartment at the bottom of the pedals is increased, thereby providing heat to the battery compartment during riding.
