Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to an automatic power-off system for heated handlebars based on riding status detection. Background Technology

[0002] In existing technologies, the throttle is a core control component of electric vehicles and motorcycles, its function being to adjust the vehicle speed by the user turning the throttle. Typically, the throttle integrates a Hall effect sensor and a magnet structure: when the user turns the throttle, the change in the relative position of the magnet and the Hall effect sensor generates a voltage signal (for example, the output voltage is approximately 0.9V when stationary, rising to over 1.3V after turning). This signal is transmitted to the vehicle controller, which then controls the motor speed, achieving acceleration or deceleration. This Hall effect-based speed control method has become an industry standard and is widely used in electric bicycles, electric motorcycles, and some electronically controlled gasoline vehicles.

[0003] However, existing throttle grips have a relatively simple function, focusing solely on vehicle speed adjustment. In practical applications, throttle grips are often used in conjunction with heated grips to provide hand heating for the rider in low-temperature environments. However, the heated grips are usually controlled independently of the throttle grip and require manual operation. Users often forget to turn off the heated grips after use, causing the heating function to continue running even when the vehicle is parked. Especially for electric vehicles, where there is no engine sound warning and the vehicle is left stationary in enclosed spaces such as garages for extended periods, continuous heating could lead to safety hazards such as overheating, short circuits, or even fires. Furthermore, some existing solutions attempt to achieve automatic power-off by detecting vehicle speed or engine status, but these solutions often require additional sensors (such as gravity sensors or speed detection modules), increasing costs and installation complexity, and may also be difficult to popularize due to wiring difficulties and low reliability.

[0004] Therefore, there is an urgent need in this field for an improved heated handle to address the potential problems caused by forgetting to turn off the heated handle. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic power-off system for heated handlebars based on riding status detection, so as to solve the problems existing in the prior art and improve the safety of using heated handlebars.

[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides an automatic power-off system for heated handlebars based on riding status detection, applied to a vehicle. The vehicle includes a frame and a control throttle operated by the user, comprising: An electrically heated handle is fitted onto the control throttle, and the electrically heated handle contains an electrically heated material. The signal acquisition unit is used to acquire riding status signals that reflect the riding status of the vehicle; The controller, electrically connected to the signal acquisition unit and the heated handlebar, is configured to: control the heated handlebar to start heating when the vehicle enters the riding state based on the riding state signal; and control the heated handlebar to stop heating after the vehicle exits the riding state.

[0007] Preferably, the signal acquisition unit is configured to acquire the throttle operation signal of the control throttle as the riding status signal; The throttle operation signal includes the voltage signal output by the Hall element installed inside the control throttle.

[0008] Preferably, the vehicle is a gasoline-powered vehicle and includes an engine; The signal acquisition unit is configured to acquire the engine's operating electrical signal as the riding status signal.

[0009] Preferably, the signal acquisition unit is configured to acquire the wheel rotation signal of the vehicle as the riding status signal.

[0010] Preferably, the signal acquisition unit is configured to acquire the vehicle's seat sensor signal as the riding status signal, wherein the vehicle's seat sensor is located under the vehicle's seat cushion and can be triggered when the user sits on the seat cushion.

[0011] Preferably, the controller is further configured to: after determining that the vehicle has exited the riding state, delay for a preset time before controlling the heated handlebar to stop heating.

[0012] Preferably, the controller is specifically configured as follows: When the output voltage of the Hall element changes from the first threshold to the second threshold, it is determined that the vehicle has entered the riding state, and the heated handlebar is controlled to start heating. When the output voltage of the Hall element recovers from the second threshold to the first threshold, it is determined that the vehicle has exited the riding state.

[0013] Preferably, the heating material is wound around the surface of the control throttle and rotates together with the control throttle.

[0014] Preferably, the power source for the heated handle is connected to the vehicle's battery.

[0015] Preferably, the heating material is a heating wire.

[0016] The present invention also provides a vehicle comprising the above-described automatic power-off system for heated handlebars based on riding status detection.

[0017] The present invention achieves the following technical effects compared to the prior art: The automatic power-off system for heated handlebars based on riding status detection provided by this invention fundamentally eliminates the safety hazards of heated handlebars compared to existing technologies, significantly improving vehicle safety. This invention controls the on / off state of the heated handlebars by automatically detecting riding status, effectively solving the problem of the heated handlebars continuing to heat after the vehicle is parked due to users forgetting to turn them off. Especially for electric vehicles without engine sound indicators, this system prevents the heated handlebars from overheating, short-circuiting, or even causing fires due to prolonged operation in enclosed spaces such as garages, achieving inherent safety.

[0018] This invention cleverly utilizes the Hall element and its output voltage signal in the vehicle's original throttle as the basis for judging the riding status. This means that there is no need to add any additional hardware devices such as gravity sensors or microswitches. The function can be achieved simply through signal line connection and controller logic optimization, which greatly reduces the material cost, installation complexity and failure rate of the system, and can be seamlessly compatible with most electric vehicles, electric motorcycles and fuel vehicles with electronic throttle on the market.

[0019] The technical solution of the present invention is not limited to Hall signals, but also covers multiple detection paths such as engine electrical signals, wheel rotation signals, and seat sensor signals, which improves the adaptability of the system in different vehicle models and scenarios (for example, engine signals can be used for fuel vehicles).

[0020] When the system detects that the riding activity has ended (such as when the throttle returns to its original position), it does not immediately cut off the power, but delays for a preset time before turning off the heating. This design effectively distinguishes between the two scenarios of "brief stop" and "end of riding," avoiding the discomfort caused by users frequently starting and stopping the heating on the handlebars while waiting at a red light or having a brief conversation. It greatly improves the practicality and user-friendliness of the product while ensuring safety. Attached Figure Description

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

In the diagram: 1. Heated handle; 2. Control throttle; 3. Controller; 4. Hall element; 5. Heating material. Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The purpose of this invention is to provide an automatic power-off system for heated handlebars based on riding status detection, so as to solve the problems existing in the prior art and improve the safety of using heated handlebars.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1 This embodiment provides an optimized and lowest-cost implementation scheme. For example... Figure 1 As shown in the schematic block diagram, the automatic power-off system for heated handlebars based on riding status detection in this embodiment mainly includes heated handlebars 1, signal acquisition unit, and controller 3.

[0027] A heated handle 1 is mounted on the vehicle's control throttle 2. The heating material 5 inside the heated handle 1 is preferably a heating wire, which is wound around the surface of the control throttle 2 and rotates with the control throttle 2. The power supply to the heated handle 1 is connected to the vehicle's battery through the vehicle's ignition switch to ensure stable power supply.

[0028] In this embodiment, the signal acquisition unit is not a separate hardware module, but rather refers to the physical connection and interface for acquiring signals from existing vehicle components. Its core function is to acquire the output voltage signal of the Hall element 4 located within the control throttle 2 as a riding status signal. Specifically, it is directly connected to the Hall signal output line of the throttle via a wire.

[0029] exist Figure 1 For illustrative purposes, the controller 3 is shown on the outside of the heated handle 1. However, in practical applications, the controller 3 can be integrated inside the heated handle 1 and electrically connected to the signal acquisition unit and the heating material 5. The controller 3 can be a microcontroller (MCU) that stores control logic internally. The controller 3 is configured to continuously monitor the output voltage of the Hall element 4.

[0030] Heating activation logic: When the controller 3 detects that the output voltage of the Hall element 4 changes from a first threshold (e.g., 0.9V representing the throttle being stationary) to a second threshold (e.g., 1.3V representing the throttle starting to rotate), it determines that the vehicle has entered riding mode (or is ready to ride). At this time, the controller 3 controls the heating circuit of the heated handlebar 1 to be turned on, and heating begins.

[0031] Heating Stop Logic: When the vehicle stops riding and the user releases the throttle, the output voltage of Hall element 4 returns from the second threshold to the first threshold. At this time, controller 3 determines that the vehicle has exited riding mode. However, to avoid frequent start-stop of the handlebars when waiting at a red light or during temporary short stops, controller 3 does not immediately cut off power, but instead initiates a delay program (e.g., a delay of 3-5 minutes). During the delay, if throttle rotation is detected again (voltage rises to the second threshold), the heating state is restarted and the delay timer is reset. If no riding signal is detected after the delay ends, controller 3 controls the heating circuit to disconnect, stopping heating.

[0032] The greatest advantage of this embodiment is that it achieves intelligent and safe automatic power-off control by using only one signal line and the vehicle's inherent Hall signal, with extremely low cost and excellent compatibility.

[0033] Example 2 This embodiment is a workaround for fuel-powered vehicles (such as motorcycles). The automatic power-off system for the heated handlebars based on riding status detection in this embodiment is similar in structure to that in Embodiment 1, with the main difference being the signal source of the signal acquisition unit.

[0034] In this embodiment, the signal acquisition unit is configured to acquire the engine's operating electrical signals as riding status signals. Specifically, this can be achieved by detecting the AC signal generated by the generator after the engine starts, or by detecting the pulse signal from the engine ignition coil. When the signal acquisition unit detects the engine start signal, it determines that the vehicle has entered a "ready to ride" state, and the controller 3 controls the heated handlebar 1 to start heating. When the engine is turned off, the signal disappears, and after a delay (logic as in Embodiment 1), the controller 3 controls the heated handlebar 1 to stop heating. This solution also eliminates the need for additional complex sensors, utilizing the inherent characteristic signals of gasoline-powered vehicles.

[0035] Example 3 This embodiment is an alternative implementation based on wheel rotation signals. The automatic power-off system for the heated handlebars based on riding status detection in this embodiment is similar in structure to Embodiment 1, but the signal acquisition unit is configured to acquire the vehicle's wheel rotation signals. For example, it can be taken from the vehicle's existing speed sensor (usually Hall effect or magnetoelectric), whose signal changes with wheel rotation. When a wheel rotation signal is detected, riding status is determined, and heating is initiated; after the wheel stops rotating for more than a preset delay, riding is determined to have ended, and heating is stopped. Although this solution may require additional signal processing or have installation considerations, its technical path is covered by this invention.

[0036] Example 4 This embodiment is an alternative implementation based on seat sensor signals. The automatic power-off system for the heated handlebars based on riding status detection in this embodiment is similar in configuration to Embodiment 1, but the signal acquisition unit is configured to acquire signals from the vehicle's seat sensor. For example, a seat sensor is installed under the vehicle's seat cushion, and the sensor is triggered when the user sits on it. The seat sensor is connected in series between the heating material 5 and the power supply circuit. When the seat sensor is on, the heating material 5 is energized and heats up; when the seat sensor is off, the heating material 5 is de-energized and stops heating. Alternatively, the seat sensor can be electrically connected to the controller 3. When the user sits on the seat cushion and the seat sensor is on, it is determined that riding is in progress, and heating is initiated. When the user leaves the seat cushion and the seat sensor is off, after a preset delay, it is determined that riding has ended, and the controller 3 controls the heating material 5 to turn off, stopping heating.

[0037] It is worth noting that in actual product design, the signal paths in the different embodiments described above are not mutually exclusive. The controller 3 of this invention can be designed to receive and process various types of riding status signals. In a preferred embodiment, the system can default to using the Hall effect throttle signal from Embodiment 1. Meanwhile, the possibility of connecting other signals (such as engine signals) is reserved on the hardware interface to accommodate the needs of different vehicle models.

[0038] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
