Description

Technical Field

[0001] This utility model relates to the field of radio charging technology, specifically to a portable handheld radio charging and power supply converter. Background Technology

[0002] A handheld radio, or simply a handheld radio, is a type of radio that is set up in contrast to vehicle-mounted or fixed radios. It is typically used while on the move and is more portable and flexible than the latter two. It is an evolutionary history from classic analog circuits (modulation / demodulation, superheterodyne) to modern radio frequency integrated circuits (frequency synthesis, high-efficiency power amplifiers), and then to digital signal processing and software-defined radio. It is an engineering art that "loads" sound onto electromagnetic waves and overcomes distance, interference, and spectrum resource limitations through various ingenious technologies to ultimately achieve reliable communication. In existing technologies, portable handheld radios are equipped with two 14.4V / 3AH lithium-ion batteries. The charging mode of lithium-ion batteries is relatively simple, limited to removing the batteries from the bottom of the radio body and charging them with a dedicated desktop charger using 220V AC power. This charging method is particularly inconvenient when working in the field for extended periods, because once the batteries are depleted and there is no AC power available for charging, the radio will be unusable. Furthermore, when the batteries are depleted and a spare battery needs to be replaced, the operator must first turn off the radio, replace the battery, and then turn it back on. During this process, the radio is in a switched-off state and cannot communicate, resulting in communication interruptions. Therefore, the limitations of the radio's battery life and charging method are key factors affecting the operator's efficiency and reliability in the field or in emergency situations.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: A portable handheld radio charging and power converter, such as Figure 1-3 As shown, it includes an upper cover plate 1 and a housing 2. A lower cover plate 3 is provided on the side of the housing 2 away from the upper cover plate 1. The upper end face of the upper cover plate 1 and the lower end face edge of the lower cover plate 3 are provided with a plurality of mounting holes 101 that are connected to the housing 2. A circular connecting cylinder 11 is provided in the middle of the upper cover plate 1. Two electrode springs 12 connected to the electrodes of the radio equipment are provided in the connecting cylinder 11. A cavity 201 is provided in the middle of the housing 2. A buck-boost charging module is provided in the cavity 201. A fixing plate 21 is provided on the side of the buck-boost charging module near the lower cover plate 3. A groove 202 for mounting the display screen is provided on one side of the housing 2. A charging hole 205 for connecting to the buck-boost charging module is provided on the outer wall of the housing 2 at one end of the groove 202. Two electrode posts 31 are provided in the middle of the lower cover plate 3. The electrode posts 31 are connected to the buck-boost charging module and the electrode springs 12. The charging hole 205 is a Type-C input interface. The buck-boost charging module supports most public or private protocols on the market, with a maximum charging and discharging power of 45W, an input voltage of DC 5-20V adaptive, and an output of DC 16.8V. The buck charging module includes a buck-boost controller IC, power MOSFETs, and solid-state capacitors or low-ESR electrolytic capacitors. The buck-boost controller IC is one of the "hearts" and "brains" of the buck-boost charging module. It is a dedicated chip that generates high-frequency PWM signals to precisely control the switching timing and duty cycle of four MOSFETs to achieve stable voltage boosting and bucking. The power inductor and power MOSFETs are used as high-speed electronic switches. A typical synchronous buck-boost circuit requires four MOSFETs, which form a full-bridge structure to control the energy switching of the input and output respectively. They are one of the main heat sources. Input / output capacitors, solid-state capacitors or low-ESR electrolytic capacitors, are used for large-capacity filtering at the input and output terminals to stabilize the voltage and absorb ripple current. Multilayer ceramic capacitors are distributed in large quantities near the power supply pins of the IC for high-frequency decoupling and filtering out noise generated by switching.

[0019] This utility model, through its wide voltage input setting (supporting DC 5-20V adaptive) and Type-C input interface configuration, enables diversified expansion of charging methods. In outdoor scenarios without mains power, users can connect various devices such as power banks, car cigarette lighter sockets, solar chargers, and hand-cranked chargers to charge the radio battery, eliminating the need for a fixed mains power supply. This completely solves the problem of the inability to recharge the battery after it is depleted during long-term outdoor work, significantly improving the radio's continuous use capability in special environments such as the field and emergencies.

[0020] The mounting holes 101 of both the upper cover plate 1 and the lower cover plate 3 are provided with screw caps 14 to fix the two cover plates to the housing 2. Figure 1 As shown.

[0021] Furthermore, both electrode springs 12 are fixed to the middle of the connecting cylinder 11 by screws, and two L-shaped electrode rotors 13 are provided on both sides of the connecting cylinder 11. The electrode rotors 13 are used to rotate and engage with the handheld radio device.

[0022] Furthermore, the lower cover plate 3 is provided with a connecting groove 301 for fixing two electrode posts 31 in the middle. Both sides of the connecting groove 301 are provided with arc-shaped spiral grooves 302. The spiral grooves 302 are used for rotating and fastening connection with the lithium-ion battery. The motor post 31 and the motor spring 12 are both connected to the step-up and step-down charging module through wires.

[0023] The L-shaped electrode rotor 13 on the upper cover plate 1 can be rotatably connected to the radio, and the arc-shaped spiral groove 302 on the lower cover plate 3 can be rotatably connected to the lithium-ion battery. The converter can be quickly assembled with the radio and battery without disassembling the battery. No special charging dock is needed; the converter can directly charge the radio or battery. The Type-C interface supports reversible insertion, further reducing the difficulty of operation in complex outdoor environments and improving the convenience of charging and power supply.

[0024] Furthermore, a plurality of heat dissipation grooves 204 are provided on one side of the housing 2. The heat dissipation grooves 204 are located on the side of the housing 2 away from the groove 202. The heat dissipation grooves 204 are used for heat dissipation of the buck-boost charging module in the cavity 201. A rectangular through hole 203 communicating with the cavity 201 is provided on one side of the housing 2. The through hole 203 is located on the side of the groove 202. The rectangular through hole 203 is used for connecting the display screen and the buck-boost charging module. The buck-boost charging module in the housing 2 has a size of 46×30mm. The buck-boost charging module is fixed to the shelf plate 21 by screws. Thermal grease is provided on the buck-boost charging module and the shelf plate 21. The thermal grease is used for heat dissipation of the buck-boost charging module.

[0025] With the heat dissipation grooves 204 and thermal grease on the housing 2, thermal grease is filled between the buck-boost charging module and the shelf 21. The dual heat dissipation structure can quickly dissipate the heat generated by the buck-boost charging module during operation, avoiding the impact of high temperature on the performance of the buck-boost charging module or damage to the equipment. This ensures the stability of the converter under high power (maximum 45W charging power). The buck-boost charging module has IC over-temperature protection, overcharge protection, over-voltage protection, and over-current protection functions, which can effectively prevent damage to radio equipment and lithium-ion batteries due to abnormal voltage / current. At the same time, the standby power consumption of the buck-boost charging module is only 100μA, reducing power loss in non-working state and taking into account both safety and energy saving.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
