[0028] Embodiment 1:

[0029] See attached Figure 1A door handle structure based on friction power generation and electromagnetic power generation, comprising a door handle 1, a transmission unit, a friction power generation component, an electromagnetic power generation component and a fixed seat 5; the door handle 1 is drivingly connected to the transmission unit; the transmission unit at least comprises a transmission gear component and a transmission shaft 21; the transmission gear component is used to drive the transmission shaft 21 to rotate when the door handle 1 is rotated; the friction power generation component at least comprises a friction power generation sheet 31 and a first matching piece 32; the first matching piece 32 is transversely arranged on one side of the fixed seat 5; the friction power generation sheet 31 is sleeved on the transmission shaft 21, and is used to contact and rub with the first matching piece 32 to generate electricity; the electromagnetic power generation component at least comprises a coil component 41 and a magnet rotating shaft 21; the door handle 1 is connected to the transmission shaft 21 by a frictional force ... sheet 31 is sleeved on the transmission shaft 21, and is used to contact The first engaging member 32 is hollow inside and connected with the mounting through hole 51, so as to form a mounting channel which runs horizontally through the fixed seat 5; the transmission shaft 21 is arranged horizontally and rotatably in the mounting channel; when the door handle 1 is rotated, the transmission shaft 21 will drive the friction power generation sheet 31 and the magnet rotor 42 to rotate at the same time, so that the friction power generation component and the electromagnetic power generation component can generate electricity at the same time. As can be seen from the above structure, the door handle 1, as one of the important structures for opening and closing the door, will generate mechanical energy when it rotates. The transmission unit at least includes a transmission gear assembly and a transmission shaft 21. The transmission gear assembly is used to transmit the power generated by the rotation of the door handle 1 to the transmission shaft 21 when the door handle 1 rotates, so that the transmission shaft 21 rotates, and the gears in the transmission gear assembly amplify the speed and rotation angle of the rotating shaft, so that the friction power generation assembly and the electromagnetic power generation assembly generate more electric energy. The friction power generation assembly generates electricity by contact friction, and can store the electric energy generated by friction through external wires and power storage devices to power the electric door lock. The friction power generation assembly at least includes a friction power generation sheet 31 and a first matching piece 32. The friction power generation sheet 31 is sleeved on the transmission shaft 21. When the transmission shaft 21 rotates, it will also drive the friction power generation sheet 31 to rotate. At this time, the friction power generation sheet 31 will generate electricity with the first matching piece 32 through contact friction. The electromagnetic power generation assembly can also store the current generated by magnetic power generation through external wires and storage devices, and power the electric door lock. The electromagnetic power generation component at least includes a coil component 41 and a magnet rotor 42, wherein the coil component 41 is fixedly installed in the installation through hole 51, and the magnet rotor 42 is sleeved on the transmission shaft 21. The magnet rotor 42 rotates synchronously when the transmission shaft 21 rotates. At this time, the magnet rotor 42 and the coil component 41 perform magnetic flux cutting motion to generate induced current to achieve the power generation function.Since the first matching member 32 is hollow inside and connected to the mounting through hole 51, a mounting channel is formed that runs horizontally through the fixing seat 5, so that the transmission shaft 21 can be rotatably inserted into the mounting channel and has enough room for movement when rotating. When the user rotates the door handle 1 when opening the door, the transmission shaft 21 is driven to rotate through the transmission gear assembly, and then the friction power generation sheet 31 and the magnet rotor 42 are driven to rotate at the same time, so that the friction power generation assembly and the friction power generation assembly generate electricity at the same time, supply power to the smart door lock, reduce the energy consumption of the electric door lock, and then reduce the frequency of battery replacement and the cost of using the electric door lock. The present invention can effectively utilize and convert mechanical energy, achieve the effect of energy saving and consumption reduction, and further improve the efficiency of energy recovery through dual-mode power generation. In addition, the present invention has a compact structure and can be applied to different scenarios and different types of electric door locks.

It can be seen from the above structure that the coil assembly 41 is installed in the mounting through hole 51 of the fixing seat 5, and the fixing seat 5 can be fixedly arranged inside the door. A plurality of magnets 422 are attached to the rotor body 421 through a plurality of mounting grooves 4211 to form a magnet rotor 42 with magnetic force. The magnet rotor 42 is fitted into the mounting through hole 51. When the magnet rotor 42 is driven by the transmission shaft 21 to rotate, the magnet rotor 42 and the coil assembly 41 perform magnetic flux cutting to generate induced current and realize the electromagnetic power generation function.

It can be seen from the above structure that when the door handle 1 rotates, the first transmission gear 25 is driven to rotate, so as to drive the first matching gear 26 to rotate, thereby causing the second transmission gear 28 on the first matching shaft 27 to rotate, and then driving the second matching gear 29 to rotate, and finally causing the transmission shaft 21 to rotate. The present invention amplifies the rotation angle and rotation speed of the transmission shaft 21 by utilizing the transmission cooperation of the first transmission gear 25, the first matching gear 26, the second transmission gear 28, and the second matching gear 29. Specifically, the sizes of the first transmission gear 25 and the second transmission gear 28 are both larger than the first matching gear 26 and the second matching gear 29 , and the specific size of each gear can be adaptively set according to requirements.
