Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a self-generating device. Background Art

[0002] Currently, most electronic devices generally use active (power) power supply structure solutions, such as batteries or dedicated drive mains power supply solutions.

[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0025] A self-generating device comprises an upper cover, a base, a motor, a vertical transmission assembly, a rotating assembly and at least two groups of limiting posts and springs; one end of the limiting post is connected to the base, and the other end of the limiting post passes through the upper cover, so as to enable the upper cover to slide on the limiting post; the spring is sleeved on the limiting post; one end of the vertical transmission assembly is connected to the upper cover, and one end of the vertical transmission assembly away from the upper cover is slidably connected to one end of the rotating assembly, so as to drive the rotating assembly to rotate; one end of the rotating assembly away from the vertical transmission assembly is rotatably connected to the motor.

[0026] From the above description, it can be seen that the beneficial effect of the utility model is that: by slidingly connecting the upper cover and the base through at least two groups of limit columns, and connecting the vertical transmission assembly to the upper cover and the rotating assembly respectively, the vertical transmission assembly and the rotating assembly are driven to move in turn by the up and down movement of the upper cover, thereby driving the motor to rotate and generate electricity; at the same time, the spring is arranged on the limit column, so that when the upper cover slides up and down along the limit column, the elastic potential energy provided by the spring makes the movement of the upper cover more stable, thereby improving the power generation efficiency.

[0027] Furthermore, the vertical transmission assembly includes a rack; one end of the rack is connected to the upper cover; and one end of the rack away from the upper cover is slidably connected to one end of the rotating assembly.

[0028] From the above description, it can be seen that the rack is used as a transmission member, so that when the upper cover moves up and down, the rack is driven to move up and down, thereby realizing energy transmission through the cooperation of the rack and the rotating component, driving the motor to generate electricity.

[0029] Furthermore, the vertical transmission assembly also includes a slider, a slide rail and a fixed plate; the fixed plate is arranged on the base; the slide rail is arranged on one side of the fixed plate; one side of the slider is connected to the rack, and the other side of the slider is slidably connected to the slide rail.

[0030] From the above description, it can be seen that by fixing the fixed plate on the base, setting a slide rail on the fixed plate, and setting a slider on the rack, the process of the rack moving up and down can remain stable and reduce shaking, thereby improving the stability of the vertical transmission assembly and reducing energy loss.

[0031] Furthermore, the rotating assembly includes a rotating shaft, a first gear, a second gear and a third gear; the third gear is arranged on the transmission rod of the motor; the first gear and the second gear are respectively sleeved on both ends of the rotating shaft, and the first gear is gear-connected with the rack, and the second gear is gear-connected with the third gear.

[0032] From the above description, it can be seen that by tooth connection between the first gear and the rack, and between the second gear and the third gear, energy is transmitted from the rack, the first gear, the second gear, and the third gear to the transmission rod of the motor in sequence, thereby realizing motor power generation.

[0033] Furthermore, the rotating assembly also includes an inertia wheel, a one-way bearing, a first tightening block and a second tightening block; the inertia wheel, the one-way bearing, the first tightening block and the second tightening block are all sleeved on the rotating shaft; the one-way bearing is sleeved in the inertia wheel; the inertia wheel is arranged on the side of the second gear away from the first gear; the first tightening block is placed on the side of the second gear away from the inertia wheel, and the second tightening block is placed on the side of the inertia wheel away from the second gear.

[0034] From the above description, it can be seen that by providing an inertia wheel and a one-way bearing, the one-way rotation of the inertia wheel is utilized to drive the second gear to rotate, thereby enabling the motor to generate electricity and improving the power generation efficiency; at the same time, the inertia wheel is fixed by the first tightening block and the second tightening block, which can avoid the problem of the inertia wheel sliding left and right, thereby improving the stability of the inertia wheel.

[0035] Furthermore, it also includes a fixing block; one end of the fixing block is connected to the base; and one end of the fixing block away from the base is connected to the motor.

[0036] It can be seen from the above description that fixing the motor by means of a fixing block can reduce the shaking of the motor during operation and reduce energy loss.

[0037] Furthermore, it also includes an end cover; the end cover is arranged at one end of the limiting column away from the base; the upper cover is movably arranged between the end cover and the base.

[0038] It can be seen from the above description that by arranging the end cover at the top end of the limiting column, the upper cover is limited between the end cover and the base to prevent the upper cover from being separated from the limiting column.

[0039] Furthermore, the base includes an annular protective wall; the spring and the limiting column are arranged on the outside of the annular protective wall; the motor, the vertical transmission assembly and the rotating assembly are arranged on the inside of the annular protective wall.

[0040] It can be seen from the above description that by providing an annular protective wall and arranging the motor, the vertical transmission assembly and the rotating assembly on the inner side of the annular protective wall, the key power generation assembly can be protected by the annular protective wall.

[0041] The self-generating device provided by the utility model can be applied to the application scenarios of passive devices, such as power supply for GPS positioning modules, or as a backup power supply for emergency power supply in case of power outage or power grid failure. The following is an explanation through specific implementation methods:
