Description

Technical Field

[0001] The present invention relates to the field of massage equipment, and in particular to a massage device and a massage bed using the massage device. Background Art

[0002] A massage bed is a home or commercial device that combines traditional massage techniques with modern technology. Its main function is to provide body massage and relaxation, helping to relieve muscle tension, promote blood circulation, and even improve sleep quality.

[0003] Existing massage beds generally use the rolling pressure of massage wheels on the human body during movement to achieve a massage effect. Such massage wheels are driven by motors and imitate human hand massage. However, due to the mechanical movement, the effect is stiff. Especially after a long period of time, the body will feel too strong and uncomfortable. Therefore, this rolling pressure massage method has shortcomings and no longer meets people's needs.

[0004] The inventor has previously developed a new type of semi-suspended electric massage bed, patent number: ZL2020205478754, which adopts a semi-suspended drive design with a simple structure. A single drive motor can easily drive the movable bed board to work. Moreover, the structure is ingenious, with few nodes of relative motion. Through the movable connection of bearings, the noise can be reduced to a very low level, and the reliability is also guaranteed accordingly. When the human body lies on the bed, the muscles pressed on the bed board can get intermittent rest due to the rising and falling of the bed board, thereby achieving a massage and relaxation function. This can be done during sleep, which helps to improve sleep quality and relax the body, promote blood circulation, especially for the elderly, especially patients who have been bedridden for a long time, can effectively prevent the formation of bedsores on the skin.

[0005] However, in actual production and use, it was found that there were still some shortcomings, because the movement range of the bed board of this design was fixed and unchanged, which could not meet people's demand for high-intensity massage in a short time.

[0006] In view of the above shortcomings, the existing technology obviously has inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0007] The object of the present invention is to provide a massage device and a massage bed using the massage device to solve the technical deficiencies raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions: A massage device includes a drum, a roller and a rocker connecting rod, wherein the roller is installed at both ends of the drum, one end of the rocker connecting rod is fixedly connected to the drum shaft, and the other end is provided with a through hole, and the roller is also provided with a groove.

[0009] An embodiment of the present application provides a massage bed, comprising a bed frame and a plurality of massage devices. A reciprocating mechanism is provided in the bed frame, and the reciprocating mechanism is provided with a fan-shaped plate. The fan-shaped plate can support the massage device under the drive of the reciprocating mechanism, thereby generating a wave-shaped massage action.

[0010] Furthermore, the sector plate matches the groove provided on the roller, and the sector plate is stuck in the groove of the roller.

[0011] Furthermore, the reciprocating mechanism includes a motor, a synchronous belt and a first synchronous shaft, the motor is connected to the first synchronous belt through a synchronous pulley, the first synchronous belt is connected to one end of the first synchronous shaft, and the other end of the first synchronous shaft is connected to a second synchronous belt symmetrical to the first synchronous belt.

[0012] Furthermore, the fan-shaped plate is also provided with a height adjustment device.

[0013] Furthermore, the height adjustment device includes a push rod motor, a second synchronous shaft, a third synchronous shaft, and a support wheel. The push rod motor is connected to the second synchronous shaft through a crank. Gears are installed at both ends of the second synchronous shaft, which engage with the gears on the third synchronous shaft. The two ends of the second synchronous shaft and the third synchronous shaft are respectively connected to an adjusting swing arm, and the adjusting swing arm is connected to the support wheel. The support wheel where the second synchronous shaft is connected is fixedly connected to the synchronous belt.

[0014] Furthermore, the support wheels use the track side plates provided on the bed body as support planes and can slide freely along the track side plates.

[0015] Furthermore, a reversing induction switch and a microcircuit control unit are provided at both ends of the bed, and the reversing induction switch and the microcircuit control unit are electrically connected to generate a motor reversing rotation signal.

[0016] Furthermore, limit protection switches are provided at both ends of the bed, and the limit protection switches are electrically connected to the microcircuit control unit for emergency shutdown and power off.

[0017] As an optional implementation scheme, the synchronous belt transmission structure can be transformed into a chain transmission structure.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] In the embodiment of the present application, the massage equipment may be a massage bed, a massage chair, etc.

[0023] Figure 1 A schematic structural diagram of a massage device provided in an embodiment of the present application.

[0024] like Figure 1 As shown, a massage device 1 includes a roller 101, a roller 102 and a rocker connecting rod 103, wherein the roller 102 is installed at both ends of the roller 101, one end of the rocker connecting rod 103 is fixedly connected to the roller shaft 102, and the other end is provided with a through hole for being fixedly installed on the bed with screws, and the roller 102 is also provided with a groove 1021.

[0025] Figure 2 A structural schematic diagram of a massage bed is provided for an embodiment of the present application, wherein the massage bed includes a bed body 2 and a plurality of the above-mentioned massage devices 1.

[0026] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the bed frame 1 is provided with a reciprocating mechanism, which is equipped with a fan-shaped plate 305. Driven by the reciprocating mechanism, the fan-shaped plate 305 can support the massage device 1, thereby producing a wave-like massage action. The fan-shaped plate 305 matches the groove provided in the roller 102, and the fan-shaped plate 305 is precisely stuck in the groove of the roller 102. The reciprocating mechanism includes a motor 301, a first synchronous belt 302, a first synchronous shaft 303, and a second synchronous belt 304. The motor 301 is connected to the first synchronous belt 302 via a pulley. The first synchronous belt 302 is connected to one end of the first synchronous shaft 303. The other end of the first synchronous shaft 303 is connected to the second synchronous belt 304, which is symmetrical with the first synchronous belt 302.

[0027] like Figure 8 or Figure 9 As shown, the fan-shaped plate 305 is also equipped with a height adjustment device, which includes a push rod motor 401, a second synchronous shaft 403, and a third synchronous shaft 404. The push rod motor 401 is connected to the second synchronous shaft 403 via a crank 402. Gears are installed at both ends of the second synchronous shaft 403, which mesh with the gears on the third synchronous shaft 404. The second and third synchronous shafts 403 and 404 are each connected to an adjustment swing arm 405 at both ends. The adjustment swing arm 405 is connected to a support wheel 406. The support wheel 406 connected to the second synchronous shaft 403 is equipped with a fixed clamping device 407, which is fixedly connected to the synchronous belt. The support wheel 406 uses the track side plate provided on the bed as a support plane and can slide freely along the track side plate track 201.

[0028] A reversing induction switch 501 and a microcircuit control unit are also provided at both ends of the bed. The reversing induction switch is electrically connected to the microcircuit control unit to generate a motor reversing rotation signal.

[0029] The two ends of the bed are also provided with limit protection switches 502, which are electrically connected to the microcircuit control unit and are used to generate emergency stop signals.

[0030] Working principle: The microcircuit control unit controls the operation of the motor 301. When the motor 301 drives the fan-shaped plate 305 to one end of the bed, it triggers the reversing sensor switch 501A, generating a reversing signal. The microcircuit control unit then controls the motor 301 to reverse direction, causing the fan-shaped plate 305 to move back until it triggers the reversing sensor switch 501B at the other end, causing the motor 301 to reverse direction again. This reciprocating motion props up the massage device under the reciprocating mechanism, producing a wave-like massage action. Adjusting the motor speed allows for different massage speeds. Because the roller 101 is bolted to the bed, it can both rotate freely around the bolts and rotate on its own, naturally stabilizing at the bottom. Driven upward by the fan-shaped plate 305, the fan-shaped plate 305 falls back to its bottom position under its own weight when it leaves the bed.

[0031] The fan-shaped plate 305 is provided with a height adjustment device, which works as follows: The push rod motor 401 contracts and moves in the direction of F1, driving the second synchronous shaft 403 and the third synchronous shaft 404 to rotate through the crank 402, and the support wheel 406 moves downward along F2, thereby raising the sector plate; the push rod motor 401 extends and moves in the reverse direction, and the support wheel 406 moves upward, thereby lowering the sector plate.

[0032] As another optional implementation scheme, the synchronous belt transmission structure can be replaced with a chain transmission structure, which should fall within the scope of protection of this patent.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
