Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle technology, specifically to a hand heating component and a mobility scooter. Background Technology
[0002] In related technologies, electric vehicle handlebars often use resistance wires or heating films to achieve heating functions. However, these methods have the following drawbacks: 1. High energy consumption: The resistance wire needs to be continuously energized for heating, resulting in low energy conversion efficiency; 2. High safety hazards: Direct contact heating may lead to localized overheating or leakage; 3. Complex maintenance: Heating elements are prone to aging and require frequent replacement. In addition, some electric vehicles are equipped with heated gloves, which contain resistance wires connected to the vehicle body via electrodes. However, this setup presents risks of cumbersome heating operation and easy wear and tear on the wiring. Utility Model Content

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0027] The following is combined with Figures 1-4 This invention describes a hand heating assembly according to an embodiment of the present invention.
[0028] The hand heating assembly of this utility model embodiment includes a handle 1, a transmitting coil 3, and a heating element 5. The transmitting coil 3 is disposed inside the handle 1. The heating element 5 is disposed outside the handle 1 and makes heat exchange contact with the hand. The heating element 5 can generate heat through eddy currents under the action of the transmitting coil 3.
[0029] According to an embodiment of this utility model, the hand heating assembly includes a transmitting coil 3 inside the handle 1 and a heating element 5 outside the handle 1 for heat exchange with the hand. When alternating current is applied to the transmitting coil 3, an alternating magnetic field is generated around the handle 1, causing eddy currents to form inside the heating element 5. This generates heat due to the Joule effect, thus heating the hand. The heating element 5 is a non-contact heating method, requiring no external wires, resulting in a simple structure, long service life, and avoiding leakage, ensuring high safety. Furthermore, the heating element 5 is heated via electromagnetic induction, resulting in high energy conversion efficiency and low energy consumption.
[0030] It should be noted that the heating element 5 is a conductor, such as graphene composite material, copper wire, and carbon wire. The heating element 5 can be fixedly installed on the outside of the handle 1, or it can be detachably installed on the outside of the handle 1. For example, the heating element 5 can be installed on the glove 2 and thus detached from the handle 1.
[0031] In some embodiments, such as Figure 1 As shown, the handle 1 includes an inner liner 11, a heat insulation layer 12, and an outer shell 13, with the heat insulation layer 12 sleeved on the inner liner 11. The transmitting coil 3 is sleeved on the heat insulation layer 12. The inner liner 11, the heat insulation layer 12, and the transmitting coil 3 are all disposed inside the outer shell 13.
[0032] By incorporating the heat insulation layer 12, heat from the user's hands is effectively prevented from being transferred to the inner liner 11 through the outer shell 13 and the transmitting coil 3, resulting in heat loss and greater comfort for the user when gripping the handle 1. In addition, the outer shell 13 separates the transmitting coil 3 from the outside environment, effectively preventing the transmitting coil 3 from being exposed and increasing its aging rate and the risk of damage from external objects, thus extending the service life of the transmitting coil 3.
[0033] For example, the inner liner 11 is a sleeve structure that fits onto the metal handlebars of the electric vehicle and is secured with screws to allow the handlebar 1 to be mounted on the electric vehicle. The outer shell 13 is made of insulating material to effectively prevent leakage of electricity from the handlebar 1 and improve the reliability of the hand heating component.
[0034] In some embodiments, the hand heating assembly further includes a temperature sensor disposed on the housing 13 and used to detect the temperature of the housing 13.
[0035] The temperature sensor is electrically connected to the vehicle controller of the electric vehicle. It is used to detect the surface temperature of the handlebar 1 in real time and control the heating power of the transmitting coil 3 through a PID algorithm. This prevents the heating element 5 from overheating and affecting user comfort, and also facilitates its rapid heating to improve user satisfaction.
[0036] For example, the vehicle controller adjusts the power of the transmitting coil 3 and, in conjunction with the temperature sensor monitoring the temperature, controls the surface temperature of the housing 13 between 35°C and 45°C.
[0037] Optionally, the insulation layer 12 is made of ceramic. This ensures that it not only has good thermal insulation performance, but also higher strength, making it less prone to breakage when subjected to impact, resulting in higher thermal insulation reliability and service life.
[0038] Optionally, the outer shell 13 is made of soft rubber. This improves the user's comfort when holding the handle 1, and also provides better insulation and heat insulation, further preventing heat loss and reducing the energy consumption of the hand heating component.
[0039] In some embodiments, the hand heating assembly further includes a glove 2, with a heating element 5 disposed on the glove 2.
[0040] Therefore, when a user wears gloves 2 and grips handle 1, the heating element 5 on gloves 2 is more reliably located within the alternating magnetic field formed by the transmitting coil 3 inside handle 1, thus achieving better eddy current heating. Furthermore, this arrangement facilitates heat exchange between the heating element 5 and the hand, resulting in better heat preservation and heating effects on the hand, while consuming less energy.
[0041] For example, glove 2 is a closed glove, meaning that the fingers 22 are all closed, and the user's hands are entirely inside the glove 2. The heating element 5 is located inside the interlayer of the glove 2 to prevent it from being exposed to the outside environment and affecting its service life. The outer layer of the glove 2 is made of heat-insulating material to effectively reduce heat loss and further reduce energy consumption.
[0042] In some embodiments, the hand heating assembly further includes a receiving coil 4, a rectifier 8, and a capacitor 9. The receiving coil 4, rectifier 8, and capacitor 9 are disposed on the glove 2. The receiving coil 4 is electrically connected to the rectifier 8, the rectifier 8 is electrically connected to the capacitor 9, and the capacitor 9 is electrically connected to the heating element 5.
[0043] The receiving coil 4 is coupled to the transmitting coil 3 to generate alternating current (AC). The rectifier 8 converts the AC to direct current (DC) and supplies it to the capacitor 9 for energy storage. The capacitor 9 is electrically connected to the heating element 5, allowing the heating element 5 to heat up after being powered on. Combined with the eddy current heating inherent in the heating element 5, the heating element 5 heats up more quickly. Furthermore, the energy stored in the capacitor 9 allows the heating element 5 to continue heating for a certain period even when the transmitting coil 3 is de-energized or the glove 2 is removed from the handle 1, resulting in longer battery life and a better user experience. In addition, the above configuration also ensures greater uniformity of heating across all parts of the heating element 5, further enhancing the user experience.
[0044] For example, the receiving coil 4, rectifier 8 and capacitor 9 are all disposed in the interlayer of the palm portion 21 of the glove 2.
[0045] Optionally, the glove 2 includes a palm portion 21 and a finger portion 22, and the heating element 5 includes heating plates or heating wires evenly distributed on each of the palm portion 21 and the finger portion 22. This results in a more uniform temperature rise across all parts of the glove 2, and greater user comfort.
[0046] In some embodiments, a pressure sensor 6 is provided on the handle 1 or in any finger portion 22.
[0047] Therefore, users can change the signal by lightly touching the pressure sensor 6, thereby enabling the start / stop and power adjustment functions of the transmitting coil 3. The start / stop and power adjustment of the hand heating component are convenient and quick.
[0048] For example, pressure sensor 6 is located at the tip of the index finger.
[0049] It should be noted that a switch or touch screen can also be installed on the handle 1 to start and stop the transmitting coil 3. Alternatively, the starting and stopping of the transmitting coil 3 and the power adjustment can be remotely controlled via a terminal device.
[0050] The mobility scooter according to an embodiment of the present invention includes a hand heating assembly as described in any of the above embodiments.
[0051] The technical advantages of the mobility scooter according to the present invention are the same as those of the hand heating component in the above embodiments, and will not be repeated here.
[0052] In some embodiments, such as Figure 4 As shown, the mobility scooter also includes a power supply 7 and an inverter 10, which are electrically connected to the transmitting coil 3 and the power supply 7. The inverter 10 is used to convert the DC power from the power supply 7 into high-frequency AC power, matching the resonant frequency of the transmitting coil 3, and supporting dynamic power adjustment.
[0053] Optionally, the mobility scooter also includes an onboard controller, a fuse, and an insulation monitoring module, both of which are electrically connected to the controller.
[0054] Therefore, when the handle 1 is too hot, the fuse will trip to stop the power supply to the transmitting coil 3. The insulation monitoring module will also stop the power supply to the transmitting coil 3 when the internal electronic components of the handle 1 leak current, thereby effectively improving the safety of the hand heating component.
[0055] In addition, the mobility scooter is equipped with overcurrent protection to effectively prevent circuit breaks and further ensure the safe operation of the hand heating components.
[0056] It should be noted that the handle 1 and glove 2 can also be paired via Bluetooth or NFC to automatically identify the user and more conveniently adjust the personalized temperature.
