In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

As shown in Figures 1-4, the present invention discloses a door closer that can recover kinetic energy, which includes a guide rail angle steel 1, a reduction box frame 2, and a kinetic energy recovery structure 3; Above the guide rail 11, the kinetic energy recovery structure 3 is installed in the reduction box frame 2; the kinetic energy recovery structure 3 includes a rack 4, a gear set 5, a generator 6 and a connecting rod 7, and the rack 4 is fixed on the guide rail angle steel In the guide rail 11 in the middle of 1, the gear set 5 and the generator 6 are installed in the reduction box frame 2, and the gear set 5 and the generator 6 are correspondingly meshed and connected, and one end of the connecting rod 7 is connected to the reduction box frame One end of 2 is connected, and the other end is fixed on the wall (not shown); through the connecting rod 7, the reduction box frame 2 is driven to move on the guide rail 11 of the guide rail angle steel. Driven by the reduction box frame 2, the gear set 5 moves on the rack 4 rolls on, makes generator 6 generate electricity.

After adopting the above structure, the present invention installs the guide rail angle steel 1 on the door, and then installs the reduction box frame 2 with the recovery kinetic energy structure 3 on the guide rail 11 of the guide rail angle steel 1, so that the reduction box frame 2 is opened when the door is opened. At the same time, the rack 4 is installed in the guide rail 11, so that the gear set 5 rolls under the action of the connecting rod 7, and then the kinetic energy is transmitted to the generator 6 through the gears in the gear set 5 to generate electricity. generator 6 to generate electricity; so the present invention can not only realize recovery of kinetic energy through the kinetic energy recovery structure 3 in the reduction box frame 2, but also realize deceleration and buffering through the generator 6.

In actual work, the transmission ratio of the rolling gear and the transmission gear of the present invention is 1:1000-1:125.

The formula for calculating the transmission ratio is:

Input speed = number of revolutions of input gear / 3s = input speed (r/s)

From the above formula it can be concluded that

When it is input from the door shaft, it will turn 1/4 circle within 3 seconds; then the input speed is 0.0834(r/s)=5(r/m); the minimum transmission ratio required by the generator to generate 24V is 1:1000.

Assuming that the transmission ratio is to be reduced by 1/8, the minimum transmission ratio required to generate 24V DC is 1:125. Then the input speed needs to be increased to 8 times. When the opening and closing time remains unchanged, the input gear (that is, the rolling gear) needs to be increased to 8 times the number of input turns; that is, the input gear (the rolling gear needs to input 2 turns).

From the above analysis, it can be obtained that when the number of turns N1 is 1/4, the required minimum transmission ratio is 1:1000; when the number of turns N2 is 2, the required minimum transmission ratio is 1:125; in summary, the input The number of turns is linear with the minimum transmission ratio.
