Moving lead wire collecting device capable of feeding back position and actuator

Abstract

The invention belongs to the technical field of smart homes, and relates to a moving lead wire collecting device capable of feeding back a position and an actuator. The lead wire collecting device comprises a shell, a wire collecting roller, a lead wire and a detection assembly, wherein a holding space is formed in the shell; the wire collecting roller is arranged in the holding space, the wire collecting roller and the shell are elastically and rotatably connected, and a wire collecting groove is formed in the surface of the wire collecting roller; the lead wire is wound in the wire collecting groove, the end, capable of being pulled out relative to the wire collecting groove, of the lead wire is marked as a movable end, the other end of the lead wire is marked as a fixed end, the movable end penetrates out of the shell, and the fixed end penetrates through the wire collecting groove; and the detection assembly detects the angle of rotation of the wire collecting roller relative to the shell so as to judge the movement distance of the movable end. According to the moving lead wire collecting device, orderly winding of the lead wire and position detection are integrated, the problem of winding of the lead wire is solved, the lead wire is prevented against the damage such as extrusion and scraping in the moving process, and the cost of additionally arranging a position detection device is saved. In addition, the moving lead wire collecting device can be used in cooperation with the actuator.

Description

technical field [0001] The invention belongs to the technical field of smart home, and in particular relates to a moving wire collection device and an actuator capable of feedbacking positions. Background technique [0002] Automation and intelligence are one of the important development directions of current household products. At present, there are some smart home products with drawers that can be pushed and pulled automatically or partitions that can be lifted and lowered automatically on the market. In these products, most of the electric actuators are arranged in such a way that the actuator body does not move and the actuator parts (such as racks, push rods, etc.) move relative to the actuator body. Realize the full opening of the drawer and the long-distance lifting of the partition. The high cost of this technical route will increase the complexity of household products, reduce the reliability of the entire product, and even bring certain safety hazards. For examp...

Problems solved by technology

However, this patent does not describe the connection method between the controller and the door switch actuator assembly, nor does it describe how to overcome the above-mentioned disadvantages caused by the reciprocating motion of the wiring harness

[0004] In addition, whether it is the technical solution of patent CN207881333U or patent CN110926090A, in order to realize automatic control, it is necessary to separately install a position detection device in the actuator to realize the judgment of the position, which not only increases the overall complexity, but also brings Additional wiring harness costs

Moreover, the accuracy and cost of conventional position detection devices are closely related

The photoelectric encoder has high precision, takes up a large space, and has poor operation reliability and high cost under low temperature or temperature shock environment; the micro switch cooperates with the rack, and the trigger method is single, and the accuracy depends on the convex point or concave on the rack. The number of slots, if the cost factor is considered, the number of bumps or grooves should be reduced. During the process of entering and exiting the drawer, due to the fast travel speed of the rack, overshooting is prone to occur.
