[0002] In the design and manufacturing process of massage machine, the wire or connecting line connecting the moving components (such as massage head, roller or other movable parts) of massage machine is a key component. These connecting lines not only need to have good electrical conductivity, but also need to withstand frequent movement and bending to ensure the stability and durability of the massage machine. After being bent for many times, the traditional round or cylindrical connecting line is prone to wire breakage, insulation layer damage and other problems, which not only affects the normal operation of the massage machine, but also may cause safety hazards.

[0003] In order to meet the high requirements of the moving components of the massage machine on the connecting line, various improved connecting lines appear on the market. However, most of these connecting lines still adopt round or approximately round structure design. When bending, the wire will be subjected to a large bending stress under a small curvature radius, accelerating the fatigue and damage process of the wire. In addition, the round connecting line also has certain limitations in layout and space utilization, especially in the case of compact internal space of the massage machine, the installation and wiring of the round connecting line may become more difficult. SUMMARY

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a circuit that can monitor the charging state of the battery in real time and automatically adjust the charging parameters according to the current state of the battery and the preset parameters to improve the charging efficiency and the service life of the battery.

[0006] A bend-resistant connecting line for massage machine for electrically connecting the moving components of the massage machine, comprising a protective sleeve and a plurality of wires wrapped in the protective sleeve,

[0007] The protective sleeve is configured in a flat shape with a width greater than a thickness, and the plurality of wires are arranged side by side in the protective sleeve along the width direction;

[0008] The bend-resistant connecting line can reduce the bending stress applied to the plurality of wires in the bending state of the flat protective sleeve during movement with the moving components.

[0009] Further, the number of wires is 2-5.

[0010] Further, the connecting wire has a center point, and the compressive stress and / or tensile stress at the center point is greater than that on both sides in the bent state.

[0011] Further, the wire includes a wire core and an insulation layer wrapped outside the wire core.

[0012] Further, the diameter of each wire ranges from 0.2 to 0.5 mm.

[0013] Further, the wire is one or more of circular, oval, flat, and irregular.

[0014] Further, the distance between adjacent wires ranges from 0.1 to 0.4 mm.

[0015] Further, the end of the connecting wire has a terminal to which an electrical connector is connected.

[0016] Further, the moving member is a massage core or an electric push rod.

[0017] Further, the plurality of wires are arranged in at least one row side by side.

[0018] Thanks to the above technical solutions, the utility model has the following advantages:

[0019] 1. The protective sleeve is configured to be flat and has a width greater than a thickness, so that the plurality of wires are arranged side by side in the protective sleeve along the width direction.

[0033] Some embodiments of the present patent will be described in detail below with reference to the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.

[0034] Please refer to Figures 1-4The utility model discloses a kind of bend-resistant connecting wires, which are used to electrically connect the moving components of a massager, to improve the durability and reliability of the connecting wires. The bend-resistant connecting wires of the utility model are particularly suitable for use in the massage machine core or electric push rod application scenarios. In the present embodiment, the connecting wires are arranged on the electric push rod 3 of the massager. The bend-resistant connecting wires include a protective sleeve 1 and a plurality of wires 2 wrapped in the protective sleeve. The protective sleeve 1 is configured in a flat shape and has a width greater than its thickness. The plurality of wires 2 are arranged side by side in the protective sleeve 1 along the width direction. During movement with the moving components, the flat protective sleeve 1 can reduce the bending stress applied to the plurality of wires 2 in the bent state. It should be noted that the number of wires 2 can be 5-10, and these wires 2 have different purposes. For example, they can be different types of power lines or signal lines. In the present embodiment, the number of wires 2 is 5. The 5 wires 2 in the present embodiment are arranged in an array to form a flat cable structure. The cable structure is wrapped with the protective sleeve 1. In other embodiments, the array arrangement of the plurality of wires 2 can be designed according to the size and arrangement requirements of the space in the massager. For example, the plurality of wires 2 can be arranged in one row and multiple columns, or in multiple rows and multiple columns. The utility model does not limit this.

[0035] It should be noted that the bend-resistant connecting wires of the utility model are particularly suitable for use in the moving components of a massager. These components need to be frequently moved and bent during the operation of the massager, so the durability and reliability of the connecting wires are extremely high. The utility model uses a flat protective sleeve 1 design, and the width is greater than the thickness, so that the plurality of wires 2 can be arranged side by side in the protective sleeve 1 along the width direction. In the bent state, the compressive stress and / or tensile stress at the center point of the connecting wires is greater than that on both sides and / or the tensile stress. This not only optimizes the use of space, making it easier to layout and install the connecting wires inside the massager, but more importantly, the flat protective sleeve 1 can more effectively distribute and reduce the bending stress applied to the plurality of wires 2 when the connecting wires are moved multiple times with the moving components of the massager and frequently bent. This significantly improves the durability and reliability of the connecting wires. The bend-resistant connecting wires for massagers and the massage chairs using the same proposed by the present patent have significant benefits in terms of bending durability, space utilization, electrical performance, connection reliability, wide applicability, and user experience. They have important practical application value and promotional significance.

[0036] Please refer to Figure 5Each wire 2 includes a plurality of cores 21, which are wrapped with an insulating sleeve 22. The insulating sleeve 22 can isolate the plurality of cores 21 in the cable structure and wrap the plurality of cores 21 and the insulating sleeve 22 wrapped thereon, so that the cores 21 are located at the center of the whole wire 2, further reducing the stress of the cores 21 and avoiding stress damage to the cores 21. Since the insulating sleeve 22 needs to have good flexibility, wear resistance and corrosion resistance, in the embodiment, the insulating sleeve 22 can be made of polyvinyl chloride (PVC) or polyurethane (PU) and the like. These materials not only have excellent physical properties, but also are easy to process and shape, and can meet the needs of connecting wires of different shapes and sizes. The number of cores 21 in each wire 2 can also be determined according to actual needs in specific implementation, which will not be described in detail here.

[0037] Further, the wires 2 in the connecting wire can adopt one or more of circular, oval, flat or irregular shapes. The selection of these shapes depends on the specific application scenario and the spatial layout between the wires 2. For example, in the case where the wires 2 need to be arranged closely, flat or irregular wires 2 can be used to save space; and in the case where the shape of the wire 2 is not required, circular or oval wires 2 can be selected to improve the convenience of manufacturing.

[0038] Further, the diameter of the wire 2 is controlled to be between 0.2-0.5mm. The selection of such a size not only ensures the conductivity of the wire 2, but also avoids the bending stress concentration caused by the over-thickness of the wire 2. The distance between the adjacent wires 2 is controlled to be between 0.1-0.4mm. The selection of such a distance is to minimize the thickness and weight of the protective sleeve 1 while ensuring that the wires 2 do not interfere with each other. At the same time, appropriate spacing between the wires 2 also helps to improve the heat dissipation performance of the connecting wire and prolong its service life.

[0039] It should be noted that the material of the core 21 of the wire 2 can be copper or copper alloy, because they have good electrical conductivity and mechanical strength. In the preferred embodiment of the utility model, the core 21 is made of oxygen-free copper (OFC), which has higher conductivity and lower resistivity, and can reduce energy loss and heat generation. The material of the insulating sleeve 22 of the wire 2 must have good insulation performance and heat resistance. In the preferred embodiment of the utility model, the insulating sleeve 22 is made of polytetrafluoroethylene (PTFE) or polyethylene (PE) and the like. These materials not only have excellent insulation performance, but also can maintain stable physical and chemical properties at high temperatures. Further, the materials of the core 21 and the insulating sleeve 22 in the embodiment are materials in the prior art, which will not be described in detail here.

[0040] Further, in order to realize the connection and signal transmission function of the connecting line, the end of the connecting line has a terminal, and the terminal is connected with the wire 2 by welding or pressure welding and the like. Then, the terminal is connected with the electric connector to realize the electrical connection between the connecting line and the massage machine moving member. The massage machine bending-resistant connecting line of the utility model effectively improves the durability and reliability of the connecting line by adopting the design of arranging the flat protective sleeve 1 and the plurality of wires 2 side by side. At the same time, through reasonable material selection and manufacturing process optimization, the performance and quality of the connecting line are further improved.

[0041] It should be noted that the structure of the bending-resistant connecting line of the utility model can also be applied to various devices / equipment which need frequent movement and small installation space, such as the massage core movement assembly and the push rod movement assembly, and here is not too much elaboration.

[0042] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
