Abstract

A gate device includes a base plate, a gate, and a power system for driving the gate to slide, the base plate has an opening, the gate is arranged on an inner side of the base plate, a rack is provided on an inner side of the gate in an opening-closing direction, and the power system includes a bi-directional power motor having a power output gear; a first transmission gear engaged with the power output gear and configured to drive a second transmission gear by a first transmission shaft, and the second transmission gear being engaged with the rack; and a third transmission gear engaged with the first transmission gear and configured to drive a sleeve component by a screw rod to make a reciprocation movement in a direction perpendicular to a sliding direction of the gate on a plane in parallel with the gate.

First claim

The invention claimed is:

1. A gate device, comprising a base plate, a gate, and a power system configured to drive the gate to slide, the base plate having an opening, the gate being arranged on an inner side of the base plate, a rack being provided on an inner side of the gate in an opening-closing direction, and the gate being driven by the power system to slide to open or close the opening, wherein the power system comprises:
a power motor, wherein the power motor has a power output gear and is a bi-directional motor;
a first transmission gear, wherein the first transmission gear is assembled with the power output gear in a meshing manner, and configured to drive a second transmission gear by a first transmission shaft, and the second transmission gear is assembled with the rack in the meshing manner; and
a third transmission gear, wherein the third transmission gear is assembled with the first transmission gear in the meshing manner, and is configured to drive a sleeve component by a screw rod to make a reciprocation movement in a direction perpendicular to a sliding direction of the gate on a plane in parallel with the gate, and the reciprocation movement of the sleeve component is configured to lock and unlock the gate.

2. The gate device according to claim 1 , wherein a first slipping device is provided between the first transmission gear and the first transmission shaft.

3. The gate device according to claim 1 , wherein a second slipping device is provided between the third transmission gear and the screw rod.

4. The gate device according to claim 1 , wherein the sleeve component is provided with an engaging foot configured to retain the gate.

5. The gate device according to claim 4 , wherein the gate is provided with an engaging arm configured to selectively engage with the engaging foot arranged on the sleeve component.

6. The gate device according to claim 1 , wherein the gate is provided with a stop strip at a side close to the sleeve component, and the stop strip is configured to limit a maximum stroke point of the movement of the sleeve component on the screw rod.

7. The gate device according to claim 6 , wherein the stop strip abuts against the sleeve component when the gate is opened fully, to lock the gate.

8. The gate device according to claim 1 , wherein the sleeve component is provided with a restricting platform at a side close to the base plate, and the restricting platform is configured to restrict the sleeve component from rotating along with the screw rod.

9. The gate device according to claim 1 , wherein the gate device further comprises a first sensor configured to detect whether the sleeve component is moved to a designated position, and the sleeve component is provided with a detecting arm configured to be selectively sensed by the first sensor.

10. The gate device according to claim 1 , further comprising an opening position detecting sensor configured to detect whether the gate is opened fully and a closing position detecting sensor configured to detect whether the gate is closed fully.
