Description

Technical Field

[0001] The utility model relates to the technical field of massage, in particular to a rolling conductive structure for massage. Background Art

[0002] In order to make the walking massage cushion suitable for various types of seats for massage, the walking massage cushion is required to be thinner and lighter. The massage chair movement needs to move back and forth on the chair back when working. The traditional movement conduction generally uses slingshot wires for electrical connection, and the automatic contraction ability of the slingshot wire is used to automatically store the redundant wire length after the movement returns.

[0003] In order to make the massage movement adapt to different users, flexible guide rails began to appear. The massage movement moves up and down along the flexible guide rails to adapt to users with different back curves, which puts higher requirements on the power supply method of the massage movement.

[0004] For example, a Chinese patent published on March 31, 2023 with patent publication number CN112510458B discloses a flexible sliding power supply component, a massage cushion and a control method thereof. The flexible conductive track of this solution can bend in one direction to adapt to massage chairs of different shapes, has good adaptability, and can be used for both ordinary cushions and curved cushions;

[0005] However, in this solution, the sliding friction between the conductive probe and the conductive strip causes great friction, which makes it inconvenient for the massage movement to move up and down, and the sliding friction causes great wear on the conductive probe; the friction between the conductive probe and the conductive strip will generate heat, and the heated conductive strip attracts the surrounding dust. During long-term use, dust is easily accumulated on the conductive strip, resulting in poor conduction between the conductive probe and the conductive strip. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a rolling conductive structure for massage and a construction method to solve the above problems.

[0007] The utility model provides the following technical solutions:

[0008] A rolling conductive structure for massage, comprising a flexible conductive track and a sliding conductive component, wherein the sliding conductive component comprises:

[0009] A lower seat and an upper cover, wherein a through slot is formed between the lower seat and the upper cover for the flexible conductive track to pass through;

[0010] The upper cover is provided with a sleeve, which has a spring, a conductor and a rolling element built in it. The conductor is located between the spring and the rolling element. The rolling element moves freely in the sleeve. The rolling element partially extends to the outside of the sleeve and is in rolling electrical connection with the flexible conductive track.

[0011] Preferably, the flexible conductive track is provided with two or more parallel slide grooves, and a conductive strip is installed on the bottom wall of each slide groove.

[0012] Preferably, one end of the sleeve extends into the corresponding slide groove, and a movable gap is left between the sleeve and the conductive strip.

[0013] Preferably, the upper cover is provided with a scraper extending in an arc shape toward the flexible conductive track, the scraper is made of an elastic material and a free end thereof is in abutment with the conductive strip.

[0014] Preferably, there are more than two groups of corresponding rolling elements in each of the slide grooves.

[0015] Preferably, two or more groups of rolling elements corresponding to the same slide groove share a conductor.

[0016] Preferably, a wave protrusion is provided on the side of the lower seat that contacts the flexible conductive track.

[0017] Preferably, the rolling element is a roller or a ball.

[0018] Preferably, the conductor is made of carbon brush.

[0019] The utility model has the following beneficial technical effects:

[0020] The rolling element is used to replace the conductive probe and the conductive strip for rolling cooperation. The rolling cooperation has low friction, which is conducive to the movement of the massage core. In addition, the rolling cooperation between the rolling element and the conductive strip causes less wear on the rolling element.

[0021] The conductive strip and the rolling element roll together to avoid frictional heating, thereby preventing the heated conductive strip from attracting surrounding dust; in the process of the massage core moving up and down, the foreign matter attached to the conductive strip is scraped off by a scraper to avoid affecting the electrical connection between the rolling element and the conductive strip.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Embodiment 1: Figure 1-8 As shown:

[0037] The massage movement 400 moves up and down along the back curve of the human body under the guidance of the flexible guide rail 300, and the massage movement 400 is electrically connected to an external power source through a conductive structure.

[0038] The flexible conductive track 1 is arranged in parallel with the flexible guide rail 300 . The flexible conductive track 1 is provided with four “T”-shaped slide grooves 11 along its length direction. The bottom wall of the slide groove 11 is provided with a conductive strip which is electrically connected to an external power source.

[0039] The sliding conductive component 2 includes a lower seat 21, an upper cover 22, a spring 3, a conductor 4 and a rolling element 5. The lower seat 21 and the upper cover 22 are fixed together by bolts, and one side of the upper cover 22 is installed on the massage movement 400 by bolts; a through groove 23 is formed between the lower seat 21 and the upper cover 22, and the flexible conductive track 1 passes through the through groove 23 relatively. The cross-sectional outer contour of the flexible conductive track 1 is slightly smaller than the contour of the through groove 23, thereby realizing the sliding fit of the sliding conductive component 2 relative to the flexible conductive track 1.

[0040] like Figure 5 As shown, a wave protrusion 211 is provided on one side of the through slot 23 of the lower seat 21, and the wave protrusion 211 abuts against the flexible conductive track 1. The wave-shaped structure is to reduce the contact area and slide smoothly on the conductive strip while ensuring the compression.

[0041] like Figure 6-7 As shown, the upper cover 22 is provided with arc-shaped scrapers 221 at both ends of one side of the through slot 23. The scrapers 221 are made of elastic material and have a certain elastic deformation ability. The free ends (tip ends) of the scrapers 221 abut against the conductive strips on the bottom wall of the corresponding slide slot 11. Each conductive strip corresponds to two scrapers 221 with opposite bending directions.

[0042] A sleeve 25 is fixedly provided on the upper cover 22. The interior of the sleeve 25 is hollow and is used to accommodate a spring 3, a conductor 4 and a rolling element 5. The conductor 4 is electrically connected to the circuit board 24 through a wire. The shorter conductive path improves the conductive efficiency and reduces the conductive loss. The conductor 4 can also be electrically connected to the circuit board 24 through the spring 3 made of conductive material. The conductor 4 and the rolling element 5 are electrically connected by abutment. The structure of the conductor 4 is compatible with the structure of the rolling element 5. The rolling element 5 is restricted by the shape of the conductor 4 and its relative position will not change arbitrarily when it rotates relative to the conductor 4.

[0043] One end of the sleeve 25 extends into the chute 11, and there is a movable gap between the sleeve 25 and the conductive strip. The movable gap is used to compensate for the deformation of the flexible conductive track 1, and the maximum height of the movable gap is less than the radius of the rolling element 5. The elastic force of the spring 3 inside the sleeve 25 pushes the rolling element 5 to contact the conductive strip of the corresponding chute 11 through the conductor 4. It should be noted that the conductor 4 slides linearly in the sleeve 25, the rolling element 5 slides linearly in the sleeve 25, and the rolling element 5 rotates relatively in the sleeve 25.

[0044] The rolling element 5 can be a roller with a wheel structure or a ball with a spherical structure.

[0045] One end of the sleeve 25 extends into the slide groove 11 to prevent the rolling element 5 from being separated from the slide groove 11 due to the deformation of the flexible conductive track 1 .

[0046] The rolling element 5 in the same slide groove 11 is connected to the same terminal of the circuit board 24. There are at least two sets of sleeves 25 corresponding to each slide groove 11 to avoid power outage due to sudden loss of contact between a conductor 4, a rolling element, or a conductive strip during operation, while the other one remains in contact to provide power.

[0047] The rolling element 5 abuts against the conductive strip of the slide groove 11. Even if the flexible conductive track 1 is deformed, during the movement of the sliding conductive component 2 relatively along the track of the flexible conductive track 1, the elastic force of the spring ensures that the rolling element 5 always abuts against the conductive strip to achieve electrical connection. The rolling element 5 itself can roll so as to roll with the conductive strip during the process.

[0048] When the sliding conductive component 2 moves relatively along the track of the flexible conductive track 1 , the free end of the scraper 221 scrapes off the powder attached to the conductive strip to avoid poor contact.

[0049] Embodiment 2:

[0050] Contains all the contents of the embodiments, except that, Figure 9-10 As shown, the interior of the sleeve 25 is hollow and is used to accommodate two springs 3, a conductor 4 and two rolling elements 5. The springs 3 and the rolling elements 5 correspond to each other one by one and are positioned appropriately. One conductor 4 can correspond to two or more rolling elements 5 at the same time, so as to avoid power failure caused by a sudden failure of one of the rolling elements 5 to make contact.

[0051] The inner cavity of the sleeve 25 limits the spring 3 from moving freely except in the radial direction.

[0052] The conductor 4 may be made of carbon brushes to reduce wear, or may be made of brass.

[0053] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
