Description

Technical Field

[0001] The utility model relates to a guide rail rolling conductive device for a massage movement. Background Art

[0002] The massage mechanism on the massage chair has the function of massaging parts of the human body and sliding and adjusting to the corresponding position according to the required massage part.

[0003] However, the massage movements installed on most massage chairs on the market are powered by directly connecting the power cord to the movement. When the massage movement slides, the movement will pull the power cord to move together. If the user accidentally bumps into it, it will cause adverse effects and pose a safety hazard. In addition, the exposed power cord will be pulled and changed its position at will, which will also lead to poor aesthetics of the massage chair and poor user experience. Utility Model Content

[0034] like Figure 1 to Figure 3 As shown, a guide rail rolling conductive device for a massage movement comprises a mounting guide rail 10 arranged on both sides of a chair frame guide rail 70, a conductive box 20 installed on both sides of a movement 80 and slidingly matched with the mounting guide rail 10; a conductive carrier 30 connected to a power line (not shown in the figure) is fixedly installed in the guide rail groove 101 of the mounting guide rail 10 along its own extension direction; a power receiving wheel 40 rollingly matched with the mounting guide rail 10, a circuit board 60 tangentially contacting the upper end of the power receiving wheel 40 and electrically connected to the movement 80, and a pressing member 50 located above the circuit board 60 are arranged in the conductive box 20, and the pressing member 50 presses the circuit board 60 to make the circuit board 60, the power receiving wheel 40 and the conductive carrier 30 contact each other, so that the conductive carrier 30 supplies power to the movement 80 through the power receiving wheel 40 and the circuit board 60. It should be noted here that the power provided to the movement 80 by the present application can be used to support the movement 80 to slide on the chair frame 70 and provide massage.

[0035] It should be noted here that the power wheel 40, the circuit board 60 and the conductive carrier 30 are all copper products with excellent conductive properties; since the conductive carrier 30 connected to the power cord is built into the assembly rail 10 fixed on the chair frame rail 70, when the powered movement 80 slides on the chair frame rail 70, it will not drag the power cord to move together, thereby avoiding the movement of the power cord and the movement of the movement 80, which not only improves the safety of the use of the movement 80, but also improves the overall aesthetics of the massage chair.

[0036] The sliding of the circuit board 60 in a direction close to or away from the conductive carrier 30 is defined as axial sliding for the following description.

[0037] Specifically, Figure 2 and Figure 3 As shown, the conductive box 20 consists of a cover plate 21 threadedly connected to the side of the movement 80, an upper buckle plate 22 and a lower buckle plate 23 aligned with the upper cover plate 21, and the upper buckle plate 22 and the lower buckle plate 23 that are buckled together are fixedly connected to the cover plate 21 by bolts; an air avoidance hole 201 is formed between the upper buckle plate 22 and the lower buckle plate 23 to allow the assembly guide rail 10 to slide, and a constraint seat 24 is provided on the upper surface of the upper buckle plate 22. The constraint seat 24 is sequentially provided with a pair of communicating limit grooves 241 for axial sliding limitation of the circuit board 60 and a rolling groove 242 that is connected to the air avoidance hole 201 and is adapted to accommodate the electric wheel 40.

[0038] It should be noted here that since the circuit board 60 is a long strip structure, considering the stability of the structural installation and the stability of the power supply, in this embodiment, one circuit board 60 is arranged in a manner of corresponding to two power-connecting wheels 40, and when a limit groove 241 is opened on the constraint seat 24, two rolling grooves 242 for adapting and accommodating the power-connecting wheel 40 are also opened at intervals.

[0039] like Figure 2 to Figure 5 As shown, the pressing member 50 is a spring 51, one force-bearing end of the spring 51 presses the inner side of the cover plate 21, and the other force-bearing end presses the upper surface of the circuit board 60, so as to force the circuit board 60 to always have a tendency to press the power-connecting wheel 40 onto the conductive carrier 30; it is worth noting that in this embodiment, the point of action of the spring 51 pressing the circuit board 60 and the power-connecting wheel 40 pressed by the circuit board 60 are in the same straight line position, so that the spring 51 can provide the circuit board 60 with a more stable pressing pressure to press the power-connecting wheel 40 and the conductive carrier 30, so as to ensure the stability of the power supply of the movement 80.

[0040] like Figure 3As shown, the two sides of the circuit board 60 are limiting parts 61, and the circuit board 60 also includes a touch-pressing part 62 located between the two limiting parts 61; the constraint seat 24 is correspondingly provided with a limiting groove 243 for the limiting part 61 to adapt and slide, and a touch-pressing groove 244 for the touch-pressing part 62 to adapt and slide. Such a design can effectively limit the left and right movement of the circuit board 60 perpendicular to the axial direction during use, and further improve the stability of the power supply of the movement 80. It should be noted here that the force-bearing end of the spring 51 forms a contact pressure with the touch-pressing part 62 of the circuit board 60, and the spring 51 is adapted to be accommodated in the touch-pressing groove 244, thereby effectively limiting the bending of the spring 51 away from the axial direction, protecting the spring 51, and improving the service life of the spring 51.

[0041] like Figure 2 and Figure 3 As shown, a stepped groove 202 is formed between the restraining seat 24 and the upper buckle plate 22, and a side plate 25 is formed on the circumferential side of the lower end surface of the cover plate 21, which is inserted into and fits with the stepped groove 202. Threaded columns 26 are provided at the top corners of the upper buckle plate 22, through holes 211 corresponding to the threaded columns 26 are provided at the top corners of the cover plate 21, and threaded holes 231 corresponding to the threaded columns 26 are provided at the top corners of the lower buckle plate 23. During assembly, the bolts are first passed through the through holes 211 on the cover plate 21, and then the bolts (not shown in the figure) are screwed and matched with the threaded columns 26 of the upper buckle plate 22 and the threaded holes 231 on the lower buckle plate 23 in sequence, thereby completing the installation of the conductive box 20.

[0042] Further, such as Figure 2 to Figure 4 As shown, the assembly guide rail 10 includes a plurality of guide rail grooves 101 arranged side by side, and the conductive carrier 30 is correspondingly arranged in each guide rail groove 101. The circuit board 60, the power receiving wheel 40 and the spring 51 in the conductive box 20 are grouped as one circuit board 60 corresponding to two power receiving wheels 40 and two springs 51, and are arranged corresponding to the conductive carrier 30 in each guide rail groove 101. This can increase the electrical contact points between the circuit board 60 and the conductive carrier 30, and improve the stability of power supply to the movement 80, that is, when one of the power receiving wheels 40 has poor contact, the other power receiving wheel 40 can continue to ensure the normal operation of the movement 80.

[0043] As time goes by, dust, debris and other pollutants may easily adhere to the surface of the conductive carrier 30 in the guide groove 101 of the assembly guide rail 10 due to static electricity, which may cause poor contact between the power receiving wheel 40 and the conductive carrier 30, affecting the stability of the power supply of the movement 80.

[0044] To solve the above problems, Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, both front and rear ends of the air avoidance hole 201 of the conductive box 20 are provided with outwardly bent chip sweeping arc plates 27 on the lower surface of the upper buckle plate 22. The chip sweeping arc plates 27 extend into the guide groove 101 of the assembly guide rail 10 and contact the upper surface of the conductive carrier 30. The chip sweeping arc plates 27 are plastic products with a certain elastic force; the upper buckle plate 22 is provided with a chip guide opening 221 which is arranged corresponding to the chip sweeping arc plates 27 and is located above the chip sweeping arc plates 27; when the movement 80 drives the conductive box 20 to slide along the extension direction of the assembly guide rail 10, the chip sweeping arc plates 27 on the conductive box 20 first clean the pollutants retained on the surface of the conductive carrier 30, and the pollutants move upward along the outer bent surface of the chip sweeping arc plates 27, and then are guided out from the chip guide opening 221 on the upper buckle plate 22 to ensure that the electric wheel 40 can always form a stable contact pressure with the conductive carrier 30, thereby solving the problem of dust, debris and other pollutants retained on the surface of the conductive carrier 30 affecting the poor contact of the contact point.

[0045] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
