[0001] The present invention relates to the technical field of vehicle-mounted equipment, and in particular to a vehicle-mounted electronic device powered by ultrasonic remote wireless charging. Background Art

[0002] With the development of wireless charging technology, more and more consumer electronic products are beginning to support wireless charging functions. However, in the field of automotive electronics, due to factors such as space limitations and electromagnetic interference, traditional wireless charging technology is difficult to apply directly. In existing vehicles, the charging and power supply of electronic devices generally adopt wired methods. This traditional method not only limits the freedom of device placement, but also affects the aesthetics and convenience of the interior of the car due to the constraints of cables. The current design of in-vehicle electronic equipment usually separates the charging and power supply functions, and the same device cannot be charged and powered at the same time, which reduces the flexibility and convenience of use. For the simultaneous use of multiple in-vehicle electronic devices, the existing power supply method requires each device to be connected to a power source or charger separately, which not only increases the complexity of wiring, but also increases the consumption of electricity and the difficulty of management.

[0003] For example, Chinese patent 202110671926.3 proposes an ultrasonic remote wireless charging and powering vehicle-mounted electronic device. The technical solution proposed can only be used on the vehicle-mounted display screen, and cannot perform ultrasonic remote wireless charging on other vehicle-mounted equipment, which seriously affects the actual use effect of wireless charging of vehicle-mounted equipment.

The system design can support multiple ultrasonic receivers working at the same time, which means that multiple on-board electronic devices can be powered at the same time to meet the growing demand for electronic devices in modern vehicles. The application of ultrasonic wireless charging technology makes the interior design of the vehicle more free and flexible, helps to optimize the utilization of the interior space of the vehicle, improves the comfort of passengers and the aesthetics of the vehicle, reduces the energy loss and waste generation (such as discarded charging cables) in traditional charging methods, complies with the environmental protection concept of energy conservation and emission reduction, and is beneficial to sustainable development. Due to the transmission characteristics of ultrasound, this charging method can adapt to a variety of vehicle models and different electronic devices, and has strong versatility and adaptability. End users will experience a more convenient and worry-free use of on-board electronic devices without having to worry about insufficient power or difficulty charging the device, thereby improving user satisfaction and comfort.

[0035] 3.

This involves adjusting the receiving sensitivity and maximizing the signal conversion efficiency.

[0036] 4. Power processing and management control: The rectifier circuit and voltage regulator circuit convert the received electrical signal into direct current suitable for device charging.

[0044] A fixing block 4 is fixedly connected to the outer wall of the bottom end of the housing 1 , and a plurality of fixing bolts 5 are threadedly connected to the top of the fixing block 4 .

[0046] An adhesive tape 29 is fixedly connected to the top of the mounting plate 12 , and an output port 13 is formed through the outer wall of the bottom end of the mounting plate 12 . The input end of the output port 13 is electrically connected to the output end of the receiving rectifier 32 .

[0047] The conversion method of electrical energy to ultrasonic wave:

[0048] Application of piezoelectric effect: When an alternating voltage is applied, piezoelectric ceramics will deform and produce mechanical vibrations. This deformation is periodic, thus generating high-frequency vibration waves, namely ultrasonic waves.

[0049] Transducer structure: Ultrasonic transducer consists of piezoelectric ceramics, matching layer, shell, etc., among which piezoelectric ceramics are the key part to realize the conversion of electrical energy into mechanical vibration energy.

[0050] Determination of operating frequency: The operating frequency of the transducer is usually close to the resonant frequency of its piezoelectric ceramic, at which time the output energy is the highest and the conversion efficiency is optimal.

[0051] Coordination of system components: including transmitting transducer, receiving transducer, control part and power supply part, etc. These components work together to achieve effective transmission of ultrasound.

[0052] The role of the power amplifier: In the ultrasonic generator, the power amplifier amplifies the modulated signal to drive the transmitting transducer to generate high-intensity ultrasonic waves.

[0053] Ultrasonic energy conversion method

[0054] Function of the receiving transducer: When the ultrasonic wave reaches the receiving transducer, the piezoelectric ceramic inside the transducer will vibrate due to the mechanical vibration of the ultrasonic wave.

[0055] Reverse application of the piezoelectric effect: Vibration causes piezoelectric ceramics to generate electric charges, converting mechanical energy into electrical energy through the positive piezoelectric effect.

[0056] Processing of electrical signals: The received electrical signals are converted into direct current by a rectifier circuit and then stabilized by a voltage stabilization circuit for subsequent use or storage.

[0057] The working principle of the present invention is: the housing 1 is installed to a suitable position by means of the fixing block 4 in cooperation with the fixing bolts 5. According to the specific situation of the vehicle, the battery 19 can be supplemented with electric energy through the power connection port 3. At the same time, the battery 19 can also be supplemented with electric energy through the transmitting plate in cooperation with the side receiving plate 2. Then, the mounting plate 12 is installed to the electrical equipment through the adhesive tape 29. During installation, it is necessary to pay attention to setting the bottom of the mounting plate 12, that is, the position of the bottom receiving plate 31, toward one end of the housing 1, and then establish an electrical connection with the electrical equipment through the power cord through the output port 13.

[0058] After the installation is completed, when it is necessary to power the electrical equipment, it is only necessary to start the equipment through the vehicle system. At this time, the electric energy of the battery 19 is rectified, filtered and stabilized through the oscillator 20, the power amplifier 21, the filter 22, the output rectifier 23 and the transducer 24, and then transmitted through the transmitting board 17, and then the transmitted ultrasonic information is received by the bottom receiving board 31, and the receiving rectifier 32 is used for inversion and rectification, and finally the electrical equipment is powered through the output port 13 and the wires.

[0059] It should be noted that, in this embodiment, the specific working modes of the ultrasonic transmission and reception of the transmitting plate 17, the bottom receiving plate 31 and the side receiving plate 2, i.e., the conversion of electric energy into ultrasonic waves, are disclosed by those skilled in the art.
