Problems solved by technology
[0002] With the development of science and technology, the car key has gradually changed from the original plug-in key structure to a wireless transmitter remote control type, which greatly facilitates the driver's operation. The transmitter car key integrates a wireless control circuit inside. It needs a certain power supply to operate, and the power consumption is small. Most of the current power supply methods use built-in button batteries. Although they can last for a long time, after the consumption is over, the panel needs to be disassembled to replace the battery. The operation process is more complicated. Trouble, if you use a hand-operated generator to supply power, you will never need to replace the battery, which is convenient for car key users

The invention discloses a precision injection molding casing of a hand-rocking power generation type automobile transmitter. The precision injection molding casing comprises a casing body, wherein a signal transmitting device is arranged in the casing; a plurality of functional press keys are convexly arranged at the surface of the signal transmitting device; a rotary shaft is arranged at the other side surface of the casing, and penetrates through the casing body; the outer side of the rotary shaft is connected with a hand-rocking rod; the hand-rocking rod is parallel with the side surface ofthe casing body; a miniature power generator is arranged in the casing; an input rotary shaft of the miniature power generator is connected with the rotary shaft, and the output end of the miniaturepower generator is connected with a bridge type rectifying circuit; the output end of the bridge type rectifying circuit is connected with the input end of a charging and discharging controller; the output end of the charging and discharging controller is connected with a lithium battery pack, and the other output end of the charging and discharging controller is connected with the signal transmitting device. By adopting the type, the precision injection molding casing has the advantage that by adopting the hand-rocking power generation type, the electric energy is provided for the internal signal transmitter to work.
Description
technical field [0001] The invention relates to the field of injection molding products, in particular to a precision injection molding casing of a hand-operated power generation automobile transmitter. Background technique [0002] With the development of science and technology, the car key has gradually changed from the original plug-in key structure to a wireless transmitter remote control type, which greatly facilitates the driver's operation. The transmitter car key integrates a wireless control circuit inside. It needs a certain power supply to operate, and the power consumption is small. Most of the current power supply methods use built-in button batteries. Although they can last for a long time, after the consumption is over, the panel needs to be disassembled to replace the battery. The operation process is more complicated. Trouble, if a hand-operated generator is used for power supply, there is no need for battery replacement forever, which is convenient for car ...
