[0055] Circuit board 203 is disposed in the mounting cavity and is fixedly connected to the first housing 201;

[0056] The power module is electrically connected to the circuit board 203. The power module includes a power source, which is a battery.

[0067] Application Examples

[0068] The technical solution adopted in this utility model is as follows: After clarifying user needs and the shortcomings of existing products on the market, the various functions of the utility model are designed. Then, the circuit design is carried out, including designing a heating circuit to ensure the heating wire operates normally under different power supply conditions and the current remains within a safe range; designing a high-power MOSFET control circuit to achieve precise control of the heating wire current; designing a power input circuit to be compatible with two power supply voltages and setting up reverse connection protection circuits; and designing peripheral circuits based on a microcontroller, including key input, temperature sensor interface, color light control, and safety protection circuits. Next, component selection is performed. The heating wire is selected based on cost and product functional requirements; the STC8G1K08A microcontroller is selected as the main control unit; the WS2812B color light is selected for temperature display based on product functional and accuracy range requirements; a high-power NMOS transistor is selected for heating wire control based on circuit parameters; and the heating wire and various basic circuit components are selected. Next, the program was designed, including a temperature control program to implement cyclical temperature settings, a temperature display program to control the color and status of the LEDs, and an intelligent heating program to implement power-off data saving and temperature sensing functions, as well as safety protection functions. Afterwards, installation and debugging were performed. All components were mounted on circuit board 203 and soldered together. The handle heating device and controller were connected, and power was turned on for testing. All functions, including temperature control, display, intelligent heating, and safety protection, were tested. Finally, the product was packaged, and products that passed the testing were sealed and packaged.

[0069] The heated handlebar includes a handlebar body structure and a heating controller structure. The handlebar body includes an internal handle sleeve, a heating element, and a rubber grip. For example... Figure 2As shown, multiple annular grooves are provided on the outer circumference of the handle barrel, and heating wires are embedded in the grooves. Then, the inner core is injection molded and coated with an outer rubber sleeve. The heating wires are connected to the power cord to heat the resistance wires, thereby achieving the purpose of heating the handle. A handle rubber sleeve is also fitted on the outside of the handle barrel.

[0070] Heating controller (see) Figure 3 It uses the STC8G1K08A microcontroller as the main control unit and has functions such as temperature regulation, temperature display, intelligent heating and various safety protection.

[0071] For temperature adjustment, a single-button step-by-step operation is adopted, embedded in two locations on the edge of the heating controller housing. It is set with temperature gradients of 10℃, 20℃, and 30℃, with an initial adjustment temperature of 40℃. Three levels are available for different step lengths and can be cycled. This design comprehensively considers the needs of users in different regions, climates, and temperatures, overcoming the shortcomings of most heating handles on the market that only offer two-level temperature adjustment.

[0072] For temperature display, a WS2812B color LED is used, embedded in two spots on the edge of the heating controller housing. Different colors indicate different adjusted temperatures; for example, the low temperature setting is blue, the high temperature setting is red, and the intermediate temperature setting is green that gradually changes from blue to red. The heating and heat preservation processes are indicated by a breathing flashing pattern.

[0073] In terms of intelligent heating, the heating controller can achieve intelligent heating function with power failure preservation. That is, after an abnormal shutdown, the system automatically saves the previous heating level and resumes heating in the original state when power is restored. The principle of intelligent heating is that the controller needs to monitor the power status in real time. Once a power failure occurs, the system can immediately detect the power interruption and save the current heating status, including the heating operating temperature, operating mode, and set temperature control parameters. To ensure that the information is still preserved after a power failure, the system saves this status data to a non-volatile memory. When the device is powered on, it reads the data saved in the memory and restores the original state for heating.

[0074] In terms of power supply, the heated handle can be powered by either 48-100V or 12V.

[0075] In terms of safety protection, the controller incorporates multiple protection mechanisms, including over-temperature protection, short-circuit protection, and fault detection. Firstly, the controller has over-temperature protection, automatically shutting off the heating after a certain period to prevent overheating and potential safety hazards such as burns or fires, ensuring user safety and property security. Short-circuit protection is also included in the controller's safety features; a fuse at the power input terminal blows when excessive current occurs, preventing overheating or fire hazards in case of a short circuit in the heating element. Simultaneously, the controller features conventional temperature sensor open-circuit and short-circuit detection functions, as well as heating element open-circuit detection. These functions can diagnose faults such as temperature sensor open-circuit and short-circuit, heating element open-circuit, and over / under voltage, providing fault indications via different LED colors or flashing frequencies. This fault detection and indication function facilitates timely problem identification and resolution for users, and also makes troubleshooting and repair easier for maintenance personnel, reducing maintenance costs and time.

[0076] The beneficial effects of this invention are as follows: All components of this invention are from domestic brands, giving it an advantage in the supply chain. This allows for effective control of production costs and enhances product competitiveness while ensuring product quality.

[0077] In terms of power supply, it is compatible with both 48-100V DC and 12-25V DC input voltages, enabling the circuit to operate normally in various power supply environments and improving the circuit's versatility and application range.

[0078] This electrically heated handlebar integrates multiple functions such as heating, temperature adjustment, temperature display, and intelligent heating. Its compact design and comprehensive functionality meet diverse user needs. Regarding temperature adjustment, this invention allows for tiered, cyclical temperature control of the electric handlebar, enabling riders to adjust the temperature according to their individual needs. This satisfies users' requirements for temperature control under different climates and temperatures, effectively overcoming the limitation of ordinary two-level temperature adjustment in conventional heated handlebars. The control method employs a single-button step-by-step operation, which is simple and intuitive, allowing users to easily adjust the temperature and significantly improving the user experience. The temperature display uses a full-color LED design, providing a highly intuitive and visually clear display of the temperature settings. Users can easily understand the heating status and temperature level of the handlebar without needing to manipulate the knobs or perform other complex operations, enhancing the product's convenience, technological sophistication, and aesthetics. For intelligent heating, this invention includes a power-off retention function, enabling intelligent control of the device and improving ease of use.

[0079] In terms of safety protection, the utility model incorporates multiple protective designs, including waterproofing and overheat protection, which enhances the reliability and durability of the product, ensures the safety of users, and extends the product's service life.
