Abstract

A carrying device includes a rack and a platform. The platform that loads goods, is moveably arranged on a handle of the rack. The carrying device further includes a sensor that detects the goods loaded on the platform, a motor that is connected to the platform, and a controlling unit that controls the motor drive the platform to move relative to the handle with a predetermined distance, according to whether the sensor detects the goods loaded on the platform.

First claim

What is claimed is:

1. A carrying device, comprising:
a rack that comprises a handle;
a platform moveably arranged on the handle for loading goods;
a sensor;
a motor that is connected to the platform;
at least one processor; and
a storage device storing a plurality of instructions, which when executed by the at least one processor, causes the at least one processor to:
determine a movement direction of the platform, the movement direction comprising a first direction towards downwards relative to the handle, and a second direction towards upwards relative to the handle;
determine whether the sensor detects the goods loaded on the platform; and
control the motor to drive the platform to move downwards relative to the handle with a predetermined distance, when the sensor detects the goods and the movement direction of the platform is determined to be the first direction; or
control the motor to drive the platform to move upwards relative to the handle with the predetermined distance, when the sensor does not detect the goods and the movement direction of the platform is determined to be the second direction.

2. The carrying device of claim 1 , wherein a rail is arranged on the handle, the rail is extended from a top end of the handle to a bottom end of the handle, and the platform is moveably fastened on the rail.

3. The carrying device of claim 1 , wherein the sensor is adjustably fixed on the handle and located above and near the platform.

4. The carrying device of claim 3 , wherein the sensor is an infrared sensor, and the processor determines that the goods are detected by the sensor when the sensor receives reflected infrared light from the goods loaded on the platform.

5. The carrying device of claim 1 , wherein the rack further comprises a support which supports the handle and the platform.

6. The carrying device of claim 5 , wherein the rack further comprises one or more wheels which are mounted on the support.

7. A method for controlling a carrying device, the carrying device comprising a rack that comprises a handle, a platform that loads goods, is moveably arranged on the handle, a sensor that detects the goods loaded on the platform, a motor that is connected to the platform, and a processor, the method comprising:
determining a movement direction of the platform, the movement direction comprising a first direction towards downwards relative to the handle, and a second direction towards upwards relative to the handle;
determining whether the sensor detects the goods loaded on the platform; and
controlling the motor to drive the platform to move downwards relative to the handle with a predetermined distance, when the sensor detects the goods and the movement direction of the platform is determined to be the first direction; or
controlling the motor to drive of the platform to move upwards relative to the handle with the predetermined distance, when the sensor does not detect the goods and the movement direction of the platform is determined to be the second direction.

8. The method of claim 7 , wherein a rail is arranged on the handle, the rail is extended from a top end of the handle to a bottom end of the handle, and the platform is moveably fastened on the rail.

9. The method of claim 7 , wherein the sensor is adjustably fixed on the handle and located above and near the platform.

10. The method of claim 9 , wherein the sensor is an infrared sensor, and the goods are detected by the sensor when the sensor receives reflected infrared light from the goods loaded on the platform.

11. The method of claim 7 , wherein the rack further comprises a support which supports the handle and the platform.

12. The method of claim 11 , wherein the rack further comprises one or more wheels which are mounted on the support.

13. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of a carrying device, causes the processor to perform a controlling method in the carrying device, the carrying device comprising a rack that comprises a handle, a platform moveably arranged on the handle for loading goods, a sensor that detects the goods loaded on the platform, and a motor that is connected to the platform, wherein the method comprises:
determining a movement direction of the platform, the movement direction comprising a first direction towards downwards relative to the handle, and a second direction towards upwards relative to the handle;
determining whether the sensor detects the goods loaded on the platform; and
controlling the motor to drive of the platform to move downwards relative to the handle with a predetermined distance, when the sensor detects the goods and the movement direction of the platform is determined to be the first direction; or
controlling the motor to drive the platform to move upwards relative to the handle with the predetermined distance, when the sensor does not detect the goods and the movement direction of the platform is determined to be the second direction.

14. The non-transitory storage medium of claim 13 , wherein a rail is arranged on the handle, the rail is extended from a top end of the handle to a bottom end of the handle, and the platform is moveably fastened on the rail.

15. The non-transitory storage medium of claim 13 , wherein the sensor is adjustably fixed on the handle and located above and near the platform.

16. The non-transitory storage medium of claim 15 , wherein the sensor is an infrared sensor, and the goods are detected by the sensor when the sensor receives reflected infrared light from the goods loaded on the platform.

17. The non-transitory storage medium of claim 13 , wherein the rack further comprises a support which supports the handle and the platform.

18. The non-transitory storage medium of claim 17 , wherein the rack further comprises one or more wheels which are mounted on the support.
