A special high-flexibility and bending-resistant photoelectric composite cable for sweeping robots and its fixing fixture

Abstract

The invention discloses a special high-flexibility and bending-resistant photoelectric composite cable for sweeping robots and a fixing clamp thereof. The outermost layer of the photoelectric composite cable is an outer rubber skin. A power cable unit, a control cable unit and an optical fiber unit are distributed inside the photoelectric composite cable. The areas between the power cable unit, the control cable unit and the optical fiber unit on one hand and the outer rubber skin on the other hand are adhered by a glue layer to form three air bags, and the air bags are filled with a polyamidefiber woven fabric. According to the special high-flexibility and bending-resistant photoelectric composite cable for sweeping robots and the fixing clamp thereof in the invention, three air bags areadded to the surface layer of the cable. On one hand, the filling of the gaps of the three cable units ensures the structural strength of the whole cable. On the other hand, the air bags with good elasticity and high bending degree can reduce the redundant filling gravity load for the cable, and when there is an external open fire, the air bags can be burnt to release nitrogen to extinguish the fire. The cable is applicable to different working conditions, and has a better use prospect.

Description

technical field [0001] The invention relates to the field of composite cables, in particular to a high-flexibility and bending-resistant photoelectric composite cable for sweeping robots and a fixing fixture thereof. Background technique [0002] Sweeping robot, also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence; the battery, motor, sensor and A variety of cables are needed between the control circuit boards, and considering that the sweeping robot sweeping robot is developing in the direction of smaller and smaller volume, the current composite cable can no longer meet the design requirements of the sweeping robot, and the current composite cable is for There are also the following defects in the adaptation of the sweeping robot: [0003] 1.

[0002] Sweeping robot, also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence; the battery, motor, sensor and A variety of cables are needed between the control circuit boards, and considering that the sweeping robot sweeping robot is developing in the direction of smaller and smaller volume, the current composite cable can no longer meet the design requirements of the sweeping robot, and the current composite cable is for There are also the following defects in the adaptation of the sweeping robot:

[0003] 1. The sweeping robot is small in size, complex in internal structure, and crowded in parts. Cables with high flexibility and bending resistance are required to be placed flexibly. The current composite cables have armored metal structures, which are poor in flexibility and bending, and are easily damaged after being squeezed. ;

[0004] 2. The sweeping robot moves for a long time, and the number of times of changing directions is frequent, and the number of impacts on the internal cable is large. The current composite cable has poor shock absorption effect, and the fixed fixture that matches it is easy to move relative to the cable under vibration. Therefore, the position of the cable is changed, and the clamping effect is poor;
