[0026] The core of the utility model is to provide a handlebar air-heating system to solve the technical problem of cold hands of the driver during driving.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1The utility model provides a handle air heating system, including a water-cooled radiator 1, a handle air guide cover 5, and a handle air heater 4 arranged inside the handle air guide cover 5; the handle air heater 4 is connected to the water-cooled radiator 1 through a pipeline, which is used to realize water circulation between the water-cooled radiator 1 and the handle air heater 4; the handle air guide cover 5 is arranged at the front end of the handle, and the handle air guide cover 5 is formed with an air inlet opening 21 and a handle receiving opening 22, which are used to transfer the heat of the handle air heater 4 to the handle. Heat can be dissipated by designing a heat dissipation fin 41 on the handle air heater 4, and the handle air heater 4 is also provided with a handle air heater water inlet 42 and a handle air heater water outlet 43 for connecting a water pipe.

[0029] It should be noted that, in this article, the direction of travel of the vehicle when it is in a non-reverse gear state is defined as forward.

[0030] Through the above structure, the heat of the cooling water in the existing water-cooled radiator 1 installed inside the vehicle can be directly used to heat the handlebars. The above vehicle can be a series of vehicles that use handlebars for driving and control, such as two-wheeled vehicles, three-wheeled vehicles, and all-terrain vehicles. The above water-cooled radiator 1 can be a device for dissipating heat for power supply equipment (such as engines, motors, and power batteries), or a device for dissipating heat for control equipment. There is no need to add additional heating equipment, which saves costs. At the same time, the heat exchange between the cooling water and the air heater accelerates the dissipation of the cooling water heat. The fixed position of the handlebar air guide hood 5 can be determined according to the overall layout of the vehicle. Optionally, the handlebar air guide hood 5 is fixedly connected to the handlebar by welding, clamping, threaded connection, etc. At the same time, the handlebar air guide hood 5 can be an integrally formed design, or it can be composed of several panels.

[0031] Reference Figure 2 Furthermore, a protective isolation member 51 is provided on the inner side of the handlebar air guide cover 5, and the protective isolation member 51 is used to separate the handlebar air heater 4 from the handlebar to prevent the driver's hands from contacting the high-temperature handlebar air heater 4.

[0032] The shape of the handle air guide cover 5, the number of pipes and the structure of the protective isolation member 51 can be designed according to the actual product structure, and no limitation is made here. Optionally, the protective plate isolation member is plate-shaped, and can also be designed as follows: Figure 2 The strip structure shown installed between the handlebar fan heater and the handle optimizes the ventilation area.

[0033] In one embodiment, the air inlet opening 21 formed on the handle air guide cover 5 is composed of a plurality of small openings, which can effectively prevent larger foreign objects from entering the air guide cover through the openings and causing damage to the internal components. The shape of the small openings can be designed according to needs. Optionally, the air inlet opening 21 can be used. Figure 2 The square design provided.

[0034] Reference Figure 1 Furthermore, the handlebar air heating system also includes a valve 6 arranged on the pipeline, which is used to control the cooling water flowing into or out of the handlebar air heater 4. Preferably, a control device 13 is provided on the vehicle. The setting position of the control device 13 can be determined according to the layout of the entire vehicle. It can be installed or integrated in the body controller position, which cooperates with the electromagnetic valve 6 arranged on the pipeline, and connects the control device 13 with the electromagnetic valve 6 to realize automatic controllability of the air heating system.

[0035] Furthermore, the handle air heater system also includes a flow detection device 7, which is connected to the control device 13 and is used to detect the flow of water in the pipeline to determine whether there is a leakage problem in the water circuit. The flow detection device 7 can be a flow sensor, which is electrically connected to the control device 13. The flow detection device 7 can be set at the water inlet and outlet 43 of the water-cooled radiator 1 or the water inlet and outlet 42 of the handle air heater, and can also be set at any position near the pipeline. When the valve 6 is in the open state, if a sudden and continuous decrease in the flow is detected, there may be a leakage problem in the water circuit.

[0036] Furthermore, the handlebar air heating system further includes a start-stop switch 8, which is electrically connected to the control device 13 to realize the start-stop control of the handlebar air heating system. The driver turns on or off the handlebar air heating system according to the ambient temperature through the start-stop switch 8. The start-stop switch 8 is preferably arranged outside the vehicle where the driver can operate it conveniently, and can be optionally arranged on the handlebar seat switch assembly 10 of the handlebar.

[0037] Furthermore, the handlebar air heating system also includes a radiator water temperature detection device and an ambient temperature detection device, and both the radiator water temperature detection device and the ambient temperature detection device are connected to the control device 13. The radiator water temperature and the ambient temperature are compared to determine whether the handlebar air heating system needs to be activated. Both the radiator water temperature detection device and the ambient temperature detection device can use sensors, which are electrically connected to the control device 13. The radiator water temperature detection device can be installed inside the radiator, and the installation position of the ambient temperature detection device can be determined according to the overall layout of the vehicle body.

[0038] Furthermore, the water-cooled radiator is designed with a variable air intake grille 12 and a motor 11 drivingly connected to the variable air intake grille 12. The opening angle of the variable air intake grille 12 is controlled by the motor 11. The motor 11 is electrically connected to the control device 13 to adjust the speed of temperature change. When the vehicle is just started and the internal components have not yet warmed up, the grille is closed to reduce ventilation with the outside world, which can achieve a rapid temperature rise effect. After warming up, the opening angle of the air intake grille is controlled according to demand, and the air intake volume is controlled to maintain the water temperature within the normal working range.

[0039] Furthermore, the handle air heating system also includes an electronic water pump 9 and a temperature detection device inside the hood. The temperature detection device inside the hood is used to detect the temperature inside the handle air guide hood 5. The electronic water pump 9 and the temperature detection device inside the hood are both electrically connected to the control device 13. The speed of the electronic water pump 9 is adjusted according to the achievement of the set temperature target, so as to control the water flow of the handle air heating system to achieve the effect of controlling the temperature of the air heater. Optionally, the electronic water pump is set at the connection between the water-cooled radiator and the pipeline or on the pipeline, and the temperature detection device inside the hood is set near the handle air heater 4.

[0040] In one embodiment, two handlebar air heaters are provided, which are distributed at the front end of the left and right handlebars of the vehicle. The water-cooled radiator is connected to the two handlebar air heaters through three pipes. Specifically, the water outlet of the water-cooled radiator is connected to the water inlet 42 of the first handlebar air heater through the first pipe, the water outlet 43 of the first handlebar air heater is connected to the water inlet 42 of the second handlebar air heater through the second pipe, and the water outlet 43 of the second handlebar air heater is connected to the water inlet of the water-cooled radiator through the third pipe.

[0041] More preferably, the pipeline is composed of a water inlet pipe 2 of the handle air heater 4 and a water outlet pipe 3 of the handle air heater 4, and both the water inlet pipe 2 of the handle air heater 4 and the water outlet pipe 3 of the handle air heater 4 are three-way pipes, the water inlet pipe 2 of the handle air heater is connected to both the two handle air heaters 4 and the water-cooled radiator 1, and the water outlet pipe 3 of the handle air heater is connected to both the two handle air heaters 4 and the water-cooled radiator 1. Through this structural setting, the water inlet of the left and right handle air heaters is divided and the water outlet is converged, so that the left and right handle air heaters can obtain similar heat dissipation, avoiding the situation where one handle is hot and the other is cold.

[0042] On the other hand, the utility model also provides a vehicle, comprising the above-mentioned handlebar air heating system, and the vehicle can solve the problem of the driver's cold hands while driving.

[0043] Reference Figure 6-Figure 7 In one embodiment, the vehicle is a fuel-powered motorcycle, and the water-cooled radiator 1 is used for cooling the engine on the motorcycle. The specific control method is as follows:

[0044] When the valve 6 is opened, the cooling water in the engine water-cooled radiator 1 enters the handlebar air heater 4 through the handlebar air heater water inlet pipe 2, and then returns to the water-cooled radiator 1 through the handlebar air heater 4 outlet pipe 3. When the cooling water passes through the handlebar air heater, the airflow during vehicle driving enters the handlebar air guide hood 5 through the air inlet opening 21 of the handlebar air guide hood 5 and flows through the heat dissipation fins 41 of the handlebar air heater, bringing the heat in the cooling water to the handlebar handle receiving opening 22, thereby achieving wind heating of the driver's hands. A three-way pipe is provided at the center of the handlebar air heater water inlet pipe 2 and the handlebar air heater outlet pipe 3 near the motorcycle handlebar cross pipe, which diverts the cooling water entering the left and right handlebar air heaters, so that the left and right handlebar air heaters can obtain similar heat dissipation.

[0045] When the valve 6 on the water inlet and outlet pipe 3 of the handlebar air heater 4 is a solenoid valve, after the vehicle engine is started, the control device 13 can determine whether to start the handlebar air heating system based on the detection signals of the radiator water temperature sensor and the ambient temperature sensor. Specifically, the control device 13 includes an engine controller and an air heating system controller. The radiator water temperature sensor and the ambient temperature sensor are connected to the air heating system controller through the engine controller, and the detection signal is transmitted to the air heating system controller through the engine controller.

[0046] When both:

[0047] Ambient temperature < threshold value (can be adjusted and calibrated by yourself);

[0048] Radiator water temperature > threshold value (can be adjusted and calibrated by yourself);

[0049] It is determined that the handlebar air heating system needs to be started, otherwise it is determined that the air heating system does not need to be started.

[0050] When it is determined that the handlebar air heating system needs to be started, the control device 13 controls the water inlet pipe electromagnetic valve 6 and the water outlet pipe electromagnetic valve 6 to open, and the cooling water in the radiator 1 enters the handlebar air heater through the handlebar air heater water inlet pipe 2, and then returns to the water-cooled radiator 1 through the handlebar air heater water outlet pipe 3. When the cooling water passes through the handlebar air heater 4, the airflow during vehicle driving enters the handlebar air guide cover 55 through the air inlet opening 21 of the handlebar air guide cover 5 and flows through the heat dissipation fins 41 of the handlebar air heater 4, bringing the heat in the cooling water to the handlebar handle receiving opening 22, thereby achieving air heating of the driver's hands. The flow sensor set at the water inlet and outlet 43 of the radiator determines whether there is a leak in the water circuit of the handlebar air heating system by calculating the flow difference of the water inlet and outlet 43. When a leak occurs, the control device 13 can close the valve 6.

[0051] When (inlet flow - outlet flow) > threshold value (adjustable and calibrated by oneself), it can be determined that there is leakage at this time, or when (inlet flow - outlet flow) * time is used to calculate and compare with the threshold value (adjustable and calibrated by oneself), the total amount of leakage can be obtained. When the total amount of leakage is too large, close the valve 6 and turn off the electronic water pump 9.

[0052] The driver can open or close the valve 6 through the start-stop switch 8 according to the riding temperature. More intelligently, the driver can set the temperature target value and threshold of the air heating system through the vehicle-computer interaction system. When the start-stop switch 8 is turned off, the control device 13 does not open the valve 6 under various working conditions. When the start-stop switch 8 is turned on, the specific opening and closing timing of the valve 6 is as follows:

[0053] When the actual temperature is greater than the set temperature target value + threshold value (which can be adjusted and calibrated by yourself), valve 6 is closed.

[0054] When the actual temperature is less than the set temperature target value – threshold value (which can be adjusted and calibrated by yourself), valve 6 opens.

[0055] When the start-stop switch is turned on, the operation of the air heating system is controlled according to the above process.

[0056] An electronic water pump 9 and a temperature sensor are added to the air heating system. The temperature signal (actual temperature) of the temperature detection device inside the handle air guide cover 5 will be transmitted to the control device 13. The control device 13 adjusts the speed of the electronic water pump 9 according to the achievement of the set temperature target, thereby controlling the water flow of the air heating system to achieve the effect of controlling the air heating temperature. The speed of the electronic water pump 9 is closed-loop regulated with temperature as feedback. The specific adjustment method is as follows:

[0057] The temperature difference is obtained by setting the temperature target value - the actual temperature;

[0058] Get appropriate PID control parameters, specific values ​​of P, I, and D through experiments in advance;

[0059] The speed is calculated by speed = P*temperature difference + I*(temperature difference integral) + D*temperature difference differential.

[0060] In order to speed up the heating effect of the water cooling system, the control motor 11 of the variable air intake grille 12 can be controlled by the control device 13 when the engine is not warmed up, so that the grille is in a closed state to achieve a rapid heating effect. When the engine is warmed up, the opening angle of the air intake grille is controlled according to the requirements of the water cooling system to maintain the water temperature within a normal working range. In another embodiment, the motor 11 can also be controlled by an engine controller, and the engine controller is in communication with the control device 13.

[0061] The switching between the two states is determined by step D1, and the specific determination method is as follows:

[0062] When the engine is not fully warmed up, the process goes to step S2 - closing the grille, at which time the engine water temperature rises rapidly; when the engine is fully warmed up, the process goes to step S1 - closed-loop regulation, in which the opening of the grille is adjusted in a closed-loop manner to maintain the water temperature of the water cooling system.

[0063] The specific logic of S1-closed loop regulation is as follows:

[0064] The temperature difference is obtained by subtracting the set water temperature from the actual water temperature, wherein the set water temperature may be the best engine water temperature obtained through experiments;

[0065] Get appropriate PID control parameters, specific values ​​of P, I, and D through experiments in advance;

[0066] The grille opening is calculated by grille opening = P*temperature difference + I*(temperature difference integral) + D*temperature difference differential.
