Problems solved by technology

[0002] Electric doors can realize electric opening and closing, and can cooperate with automatic control devices such as sensors to realize automatic opening and closing, so they are widely used, such as elevator doors, hotel lobby doors, bank lobby doors, and other relatively high-end or high-safety requirements. In places, electric doors generally require fast opening and slow closing to meet the requirements of high door opening efficiency and high door closing safety factor. At present, the speed regulation of electric doors generally adopts motor speed control system or clutch to switch gears with different speed ratios. To achieve different speeds of door opening and closing, the above-mentioned system has disadvantages such as complex structure of the control system, high cost, high failure rate, and high maintenance cost.
At the same time, the function of its mechanical transmission device is single, and it cannot be integrated to meet the requirements of mechanical forward and reverse rotation at different speeds.

Embodiment 1

[0023] Such as figure 1 As shown, an electric door integrated transmission box includes:

[0024] Transmission box 9, planetary gear, door opening driving gear 2, door closing driving gear 4, driving shaft 3, door opening driven gear 5, door closing driven gear 7 and driven shaft 6, the door opening driving gear 2 and door closing driving gear 4 are coaxially connected On the drive shaft 3, the drive shaft 3 is in transmission connection with the output shaft of the planetary gear, and the input shaft of the planetary gear is in transmission connection with the power system 1 of the electric door; the planetary gear includes a sun gear 12, Two planetary gears 11 and a planetary carrier 13, the sun gear 12 is fixed and coaxially connected with the input shaft, the two planetary gears 11 are both rotatably connected to the planetary carrier 13, and the output shaft is fixedly connected to the on the rotation axis of the planet carrier. The planetary gears, the door-opening dri...

Embodiment 2

[0030] The rest are the same as in Embodiment 1, except that the door-opening driven gear and the door-closing driven gear are respectively provided with a one-way transmission device that rotates synchronously with the driven shaft in one direction and freely rotates around the driven shaft in the other direction. A one-way device is opposite to the follow-up direction of the driven shaft. And the driving gear 2 for opening the door and the driving gear 4 for closing the door are fixedly connected with the drive shaft 3 .

Embodiment 3

[0032] The rest are the same as in Embodiment 1, except that the electric door integrated transmission box also includes a door-opening reduction box and a door-closing reduction box, the door-opening driving gear 2, the door-closing driving gear 4 and the door-opening passive gear 5 and the door-closing passive gear 7 The door-opening reduction gearbox and the door-closing reduction gearbox are matched and meshed respectively; in this way, a more optimized speed ratio and torque transmission can be realized.

[0033] In the above embodiments, the one-way transmission device is a one-way bearing, one-way clutch or one-way gear that rotates synchronously with the driving shaft or the driven shaft in one direction and freely rotates around the driving shaft or the driven shaft in the other direction. And other one-way transmissions similar to bicycle flywheel structure. Since there are many similar structures in the prior art, details are not described here. Similarly, the numb...

Abstract

The invention discloses an integrated transmission box of an electric door, which can realize fast opening and slow closing of the electric door through a simple structure by utilizing two sets of one-way transmission devices with opposite transmission directions and has the advantages of simple structure, low cost, and low failure rate and manufacturing cost. Simultaneously, the devices above and a planetary gear speed-reduction device are integrally arranged in a same transmission box body so as to solve the problem that a mechanical transmission device has a single function,, so that the whole transmission box is capable of integrally meeting requirements on the output at different rotation speeds with mechanical positive and negative rotation.
