[0009] Furthermore, the upper magnet and the movable magnet, and the movable magnet and the lower magnet have magnetic poles of the same polarity.

[0010] Wherein, the movable magnet includes one or more cylindrical magnets.

[0011] Furthermore, two ends of the copper wire group are electrically connected to a rectifier, the rectifier is electrically connected to a voltage regulator, and the voltage regulator is electrically connected to a battery in the electronic product.

[0012] Furthermore, a receiving cavity corresponding to the shell is provided inside the electronic product, and the shell is arranged in the receiving cavity.

[0013] The beneficial effects of the present invention are as follows: the built-in power generation device of the electronic product of the present invention is an independent power generation body, which does not affect the operation of other components inside the electronic product, and is only connected to the electronic product to achieve the charging function; the power generation device has a simple structure and high working efficiency, and can achieve the effect of charging the battery of the electronic product at a very low cost; when it is particularly applied to mobile phones, when the mobile phone has no power and there is no charging device nearby, the mobile phone can be waved vigorously to help charge the mobile phone for emergency use, which is convenient to use.

[0017] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. The present application can be implemented in a variety of different forms and is not limited to the implementation described in this embodiment. The purpose of providing the following specific implementations is to facilitate a clearer and more thorough understanding of the disclosure of the present application, wherein words indicating directions such as up, down, left, and right are only for the position of the structure shown in the corresponding drawings.

[0018] See also Figure 1 As shown, the present invention relates to a built-in power generation device for an electronic product, comprising a hollow cylindrical shell 1, an upper magnet 2 is arranged on the top of the shell 1, a lower magnet 3 is arranged on the bottom of the shell 1, and a movable magnet 4 suspended inside the shell 1 is arranged between the upper magnet 2 and the lower magnet 3. One or more groups of copper wire groups 5 are wound around the outside of the shell 1, and both ends of the copper wire group 5 are electrically connected to a battery in the electronic product through a rectifier 6 and a voltage stabilizer 7 in sequence; when a force is applied to the shell 1 in the up and down directions, the movable magnet 4 moves back and forth inside the shell 1 and generates current to charge the battery.

[0019] In this embodiment, the shell 1 can be designed as a cylinder, an elliptical cylinder or other cylinders, and the shell 1 adopts an insulating material that does not affect magnetism, preferably a PMMA acrylic plastic shell 1, and the surface of the copper wire group 5 is coated with insulating paint; wherein, the copper wire groups 5 are connected in series or in parallel and tightly wound to ensure more wires and more induced currents under the same conditions; both ends of the copper wire group 5 are electrically connected to the rectifier 6, the rectifier 6 is electrically connected to the voltage regulator 7, and the voltage regulator 6 is electrically connected to the battery in the electronic product, so the built-in power generation device charges the battery of the electronic product after rectification and voltage stabilization.

[0020] In this embodiment, the upper magnet 2 and the lower magnet 3 are both fixedly connected with the shell 1, and a lubricant is provided inside the shell 1 to facilitate sliding between the movable magnet 4 and the shell, thereby reducing the friction between the movable magnet 4 and the inner surface of the shell 1. Among them, the upper magnet 2 and the movable magnet 4, and the movable magnet 4 and the lower magnet 3 are the same poles, for example, the bottom surface of the upper magnet 2 is the S pole, the top of the movable magnet 4 is also the S pole, and the bottom of the movable magnet 4 is the N pole, and the top of the lower magnet 3 is also the N pole. By using the principle of magnet repulsion of the same pole, the movable magnet 4 is suspended inside the cylindrical shell 1; in addition, the movable magnet 4 includes one or more cylindrical magnets, and one or more magnets can be used according to actual needs.

[0021] It should be noted that this embodiment is a power generation device invented based on the principle of magnetoelectricity. The principle of magnetoelectricity is that when a part of the conductor of a closed circuit moves to cut the magnetic lines of force, a phenomenon called electromagnetic induction will generate current on the conductor, and the generated current is called induced current.

[0022] When the built-in power generation device of the electronic product of this embodiment is installed, it is necessary to provide a receiving cavity 9 corresponding to the built-in power generation device inside the electronic product, for example, Figure 2 As shown, the built-in power generation device is installed in the accommodating cavity 9 of the mobile phone shell 8. Its working principle is as follows: you only need to wave the mobile phone or other electronic products installed with the power generation device vigorously, and the movable magnet 4 in the power generation device will slide quickly, and the movable magnet 4 will move back and forth quickly inside the shell 1 by using the principle of magnet repulsion of the same sex. Therefore, when using, you only need to wave the electronic product regularly, and the movable magnet 4 inside the power generation device will move back and forth quickly, and the magnetic lines of force generated by the moving magnet 4 will cut the copper wires of the copper wire group 5 on the surface of the shell 1, thereby generating current, and the current passes through the rectifier 6 and the voltage regulator 7 to charge the battery of the electronic product.

[0023] Compared with the prior art, the built-in power generation device of the electronic product in this embodiment is an independent power generation body, which does not affect the operation of other components inside the electronic product, and is only connected to the electronic product to achieve the charging function; the power generation device has a simple structure and high working efficiency, and can achieve the effect of charging the battery of the electronic product at a very low cost; especially when it is applied to mobile phones, when the mobile phone has no power and there is no charging device nearby, the mobile phone can be waved vigorously to help charge the mobile phone for emergency use.

[0024] It should be further explained that, unless otherwise clearly specified and limited, terms such as "setting" and "installation" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
