Description

Technical Field

[0001] The present invention relates to the field of massage devices, and particularly to a massage bed. Background Art

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

[0003] For existing massage beds, generally, the rolling pressure generated by massage wheels during movement on the human body is used to achieve the massage effect. Such massage wheels are driven by motors to imitate the movement of human hands for massage. However, because they are all mechanical actions, the effect will be rigid. Especially after a long time of pressing, the body will feel that the force is too large and uncomfortable. Therefore, this rolling pressure massage method has deficiencies and no longer meets people's needs.

[0004] Previously, the inventor also developed a new type of semi-suspended electric massage bed, patent number: ZL2020205478754. It 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 relative movement nodes. Through bearing movable connections, the noise can be reduced to a very low level, and the reliability is correspondingly guaranteed. When a person lies on the bed, the muscles pressed on the bed board can get intermittent rest due to the lifting and lowering of the bed board, thus achieving the massage and relaxation function. This can be carried out during sleep, which helps to improve sleep quality, relax the body, and promote blood circulation. Especially for the elderly, especially bedridden patients, it can effectively prevent the formation of bedsores on the skin.

[0005] However, in actual production and use, it is found that there are still deficiencies. Because the movement amplitude of the bed board in this design is fixed and unchanged, it cannot meet people's massage needs for strong force in a short time.

[0006] In view of the above deficiencies, the existing technology is obviously inconvenient and defective in actual use, so it is necessary to make improvements. Summary of the Invention

[0007] The purpose of the present invention is to provide a massage bed to solve the technical deficiency problems raised in the above background art.

[0008] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] A massage bed, comprising a bed body and a plurality of massage devices, wherein a reciprocating mechanism is provided inside the bed body, the reciprocating mechanism is provided with a sector plate, and the sector plate can support the massage device under the drive of the reciprocating mechanism, so as to generate a wavy massage action; the massage device includes a roller, a roller and a rocker connecting rod, the roller is installed at both ends of the roller, one end of the rocker connecting rod is fixedly connected to the roller shaft, the other end is provided with a through hole, the roller is also provided with a groove, and the sector plate matches the groove provided on the roller, and the sector plate is stuck in the groove of the roller; the sector plate is also provided with a height adjustment device.

[0010] Further, 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 symmetric to the first synchronous belt.

[0011] Further, 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 and are engaged with the gears on the third synchronous shaft. Adjusting swing arms are connected to both ends of the second synchronous shaft and the third synchronous shaft, the adjusting swing arms are connected to the support wheels, and the support wheel connected to the second synchronous shaft is fixedly connected to the synchronous belt.

[0012] Further, the support wheel uses the track side plate provided on the bed body as a support plane and can slide freely along the track side plate.

[0013] Further, a commutation induction switch and a microcircuit control unit are also provided at both ends of the bed body. The commutation induction switch and the microcircuit control unit are electrically connected to generate a motor commutation rotation signal.

[0014] Further, limit protection switches are also provided at both ends of the bed body. The limit protection switches and the microcircuit control unit are electrically connected for emergency shutdown and power off.

[0015] As an alternative implementation, the synchronous belt drive structure can be changed to a chain drive structure.

[0028] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0029] In the embodiments of the present application, the massage device may be a massage bed, a massage chair, etc.

[0030] Figure 1 Schematic structural diagram of a massage device provided by an embodiment of the present application.

[0031] As Figure 1 shown, a massage device 1 includes a roller 101, a roller 102 and a rocker connecting rod 103. Among them, 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 screw-fixed installation on the bed body. The roller 102 is also provided with a groove 1021.

[0032] Figure 2 The structural schematic diagram of a massage bed is provided for an embodiment of the present application, including a bed body 2 and a plurality of the above-mentioned massage devices 1.

[0033] As Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a reciprocating mechanism is provided in the bed frame 1. The reciprocating mechanism is provided with a sector plate 305. The sector plate 305 can support the massage device 1 under the drive of the reciprocating mechanism, thereby generating a wavy massage action. The sector plate 305 matches the groove provided on the roller 102, and the sector plate 305 just fits into 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 through a pulley. The first synchronous belt 302 is connected to one end of the first synchronous shaft 303, and the other end of the first synchronous shaft 303 is connected to the second synchronous belt 304 symmetrical to the first synchronous belt 302.

[0034] As Figure 8 As shown, the sector plate 305 is further provided with a height adjustment device. The height adjustment device includes a push rod motor 401, a second synchronous shaft 403, a third synchronous shaft 404. The push rod motor 401 is connected to the second synchronous shaft 403 through a crank 402. Gears are installed at both ends of the second synchronous shaft 403 and are engaged with the gears on the third synchronous shaft 404. Adjusting swing arms 405 are connected to both ends of the second synchronous shaft 403 and the third synchronous shaft 404. The adjusting swing arms 405 are connected to support wheels 406. A fixed clamping device 407 is provided at the support wheel 406 connected to the second synchronous shaft 403 and is fixedly connected to the synchronous belt. The support wheel 406 uses the track side plate provided on the bed body as a support plane and can slide freely along the track 201 of the track side plate.

[0035] Reversing induction switches 501 and a microcircuit control unit are further provided at both ends of the bed body. The reversing induction switches are electrically connected to the microcircuit control unit and are used to generate a motor reversing rotation signal.

[0036] Limit protection switches 502 are further provided at both ends of the bed body and are electrically connected to the microcircuit control unit and are used to generate an emergency stop signal.

[0037] Working principle:

[0038] The microcircuit control unit controls the operation of the motor 301. When the motor 301 drives the sector plate 305 to move to one end of the bed, it touches the commutation induction switch 501A to generate a commutation signal. The microcircuit control unit controls the motor 301 to work in the reverse direction, and the sector plate 305 moves back until it touches the commutation induction switch 501B at the other end. Then the motor 301 works in the reverse direction again, and so on. Driven by the reciprocating mechanism, the sector plate 305 supports the massage device, thus generating a wavy massage action. By adjusting the motor speed, different massage speeds can be obtained. Since the roller 101 is installed on the bed body by bolts, the roller 101 can rotate freely around the bolts and can also rotate by itself. In the natural state, it is in the lowest position. It moves upward under the action of the sector plate 305. When the sector plate 305 leaves, it falls back to the lowest position under its own weight.

[0039] The sector plate 305 is provided with a height adjustment device, and it works as follows:

[0040] As Figure 8 shown, when the push rod motor 401 contracts, it drives the second synchronous shaft 403 (rotating along the direction of F1B) through the crank 402, and drives the third synchronous shaft 404 to rotate (rotating along the direction of F1A) through the gear. The supporting wheel 406 moves downward along F2. However, since the supporting wheel supports on the bed frame, it forces the sector plate to rise; when the push rod motor 401 extends, it acts in the reverse direction, and the supporting wheel 406 moves upward, forcing the sector plate to lower.

[0041] As another alternative implementation, the synchronous belt drive structure can be replaced with a chain drive structure, which should fall within the protection scope of this patent.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
