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. When the speed of the motor is the same, the output speed and torque are the same. In order to achieve fast opening and slow closing, the speed regulation generally adopts the motor speed control system or the clutch to switch gears with different speed ratios to realize door opening and closing. The above-mentioned system has the disadvantages of complex structure of the control system, high cost, high failure rate, and high maintenance cost.
At the same time, electric doors are required to have an anti-pinch function to prevent personal and equipment safety accidents. At present, electric doors are generally detected by sensors, and the obstruction signal is transmitted to the electric door electric control device to control the electric door to stop closing and reverse open, so that Avoid accidents, but the system structure is complicated, the cost is high, and failures are prone to occur. For example, the possibility of sensor failure brings certain safety hazards to the system

Embodiment 1

[0038] Such as figure 1 , figure 2 , image 3 As shown, an electric door integrated transmission box includes:

[0039] An electric door integrated transmission box, comprising:

[0040] Transmission box 9, torque clutch 14 and forward and reverse non-constant speed output gear set;

[0041] The positive and negative non-constant speed output gear set is provided with a driving shaft 3 for torque input and a driven shaft 6 for outputting torque, as well as a door opening driving gear 2, a door closing driving gear 4, a door opening driven gear 5 and a door closing driven gear 7;

[0042] The drive shaft 3 is in transmission connection with the power system 1 of the electric door;

[0043] The torsion clutch 14 is provided between the driven shaft 6 and the opening and closing device 8 of the electric door; the torsion clutch 14 includes a power input shaft 22 and a power output shaft 27;

[0044] The door-opening driven gear 5 and the door-closing driven gear 7 are coaxi...

Embodiment 2

[0060] The rest are the same as in Embodiment 1, the difference is that the electric door anti-pinch device is also provided with a sensor for detecting the torque, the angle of rotation of the torque output slider 6 or the position of the torque output slider 6, and the sensor is connected with the power system electrical connection. When an obstacle is encountered, the sensor detects the relevant variable, controls the power system 1 to reverse, and makes the electric door open to facilitate removal of the obstacle.

Abstract

The invention discloses an integrated transmission case for an electronically operated gate. The integrated transmission case adopts two one-way transmissions in opposite directions and rapid opening and slow closing of the electronically operated gate can be realized by a simple structure, so that the integrated transmission case has the advantages of simple structure, low construction cost, low failure rate and low maintaining cost. Meanwhile, the transmission case and a planetary gear reduction gear can be integrally installed in the same transmission case body, so that the problem of single function of a mechanical transmission can be overcome and the whole transmission case can integrally complete mechanical outputs of forward and backward rotation at different speeds.
