Description

Technical Field

[0001] This utility model relates to the field of functional furniture, and in particular to a variable amplitude horizontal rhythmic furniture. Background Technology

[0002] Sofas, beds, and other furniture are essential resting devices in people's lives. Driven by digitalization and globalization, the pace of life in modern society is constantly accelerating. Long working hours, high-intensity work environments, and the pursuit of results often leave people in a state of tension and anxiety.

[0003] Rhythm expert Chien Chih-Lung compiled his research findings in the book "Rhythm Therapy," which offers people a highly effective way to rest. Horizontal rhythm therapy integrates theories of ergonomics and hemodynamics with high-tech methods and mattresses. The interaction between the heartbeat wave and the horizontal rhythm wave within the blood vessels creates an enhanced beat frequency. This increased blood flow and velocity from the beat frequency is the principle behind the physiological effects of horizontal rhythm therapy.

[0004] The effect of horizontal rhythm:

[0005] 1. Low-frequency rhythmic movements stimulate the brain to secrete melatonin, effectively inhibiting the excitation of the sympathetic nervous system, thereby reducing mental stress, relieving fatigue, improving insomnia, and enhancing sleep quality. Clinical trial data shows that rhythmic movements improve sleep quality and prolong sleep duration.

[0006] 2. Through mid-frequency rhythmic movements, the diaphragm tissue is pushed upwards to massage the heart and lungs, and downwards to massage the intestines. This regular rhythmic movement makes the entire abdomen and chest soft and relaxed, effectively promoting gastrointestinal motility, aiding digestion, improving the immunity of the gastrointestinal mucosa, regulating gastrointestinal motility, and benefiting the secretion of large intestine glands.

[0007] 3. It can generate a large amount of nitric oxide in the human body, increasing blood flow to all tissues, dilating blood vessels, ensuring blood supply to the heart, accelerating blood circulation, nourishing all tissues, and metabolizing blood waste. Wherever there is blood flow in the body, the blood cells of various organs can be repaired, thereby greatly reducing the incidence of cardiovascular and cerebrovascular diseases.

[0008] Therefore, enabling furniture to move horizontally can be beneficial to the health of users. Chinese patent application number 202211004016.0 discloses "a horizontally moving bed". The horizontally moving bed includes a frame, on which a bed board is mounted and guided to move in the left and right direction. The frame is provided with a drive mechanism that drives the bed board to move left and right in the horizontal direction. The drive mechanism includes a drive motor mounted on the frame and an eccentric shaft whose rotation axis extends in the front and back direction. The drive motor and the eccentric shaft are connected by a transmission belt mechanism. A transmission sleeve that cooperates with the eccentric shaft is provided on the bed board.

[0009] In use, the drive motor rotates the eccentric shaft, which engages with the inner wall of the transmission sleeve, thereby moving the bed board back and forth in the left and right directions to achieve horizontal rhythm. The problem with existing horizontal rhythm beds is that the rhythm amplitude of existing horizontal rhythm beds is fixed and cannot be adjusted, thus failing to meet the needs of different rhythm amplitude applications. Utility Model Content

[0010] The purpose of this invention is to provide a variable amplitude horizontal rhythmic furniture with adjustable horizontal rhythm amplitude.

[0011] To solve the above-mentioned technical problems, the technical solution of this utility model for a variable amplitude horizontal rhythmic furniture is as follows:

[0012] A variable-amplitude horizontally rhythmic furniture includes a fixed frame, on which a movable frame is guided and moved in a left-right direction. A drive mechanism is provided between the fixed frame and the movable frame to drive the movable frame to reciprocate in the left-right direction. The drive mechanism includes an eccentric shaft with a rotation axis extending in a front-back direction and rotatably mounted on the fixed frame. The drive mechanism also includes an eccentric sleeve with a rotation axis extending in a front-back direction and rotatably mounted on the movable frame. The eccentric sleeve has an inner hole and an outer circumferential surface eccentrically positioned relative to the inner hole. The outer circumferential surface of the eccentric sleeve is rotatably engaged with the movable frame via an outer bearing. An inner bearing is provided on the inner wall of the eccentric sleeve. The eccentric shaft has an eccentric portion that engages with the inner bearing for force transmission. An angle adjustment mechanism is provided on the movable frame to adjust the rotation angle of the eccentric sleeve relative to the movable frame.

[0013] Furthermore, the horizontally rhythmic furniture is a horizontally rhythmic sofa or a horizontally rhythmic bed.

[0014] Furthermore, the fixed frame is equipped with a guide mechanism that coordinates with the movable frame to guide its movement in the left and right directions.

[0015] Furthermore, the left end of the movable frame is provided with two left guide rods arranged side by side at intervals in the front-back direction, and the right end of the movable frame is provided with two right guide rods arranged side by side at intervals in the front-back direction. The guiding mechanism includes guide wheel sets corresponding to each guide rod. The guide wheel set includes a wheel set bracket. Two lower rollers arranged left and right are rotatably mounted on the wheel set bracket. An upper roller located above the lower rollers is also rotatably mounted on the wheel set bracket. Each guide rod is located between the upper roller and the two lower rollers of the corresponding guide wheel set.

[0016] Furthermore, the movable frame includes a left crossbeam extending in the front-back direction and a right crossbeam extending in the front-back direction, with the left ends of the two left guide rods fixed to the left crossbeam and the right ends of the two right guide rods fixed to the right crossbeam.

[0017] Furthermore, a transmission frame is provided on the movable frame, and an eccentric sleeve support is provided on the transmission frame. The eccentric sleeve is rotatably engaged with the eccentric sleeve support through the outer bearing. The angle adjustment mechanism includes a telescopic cylinder provided on the transmission frame. One end of the telescopic cylinder is connected to the transmission frame, and the other end of the telescopic cylinder is connected to the eccentric sleeve.

[0018] Furthermore, an adjusting arm is fixed on the eccentric sleeve, and a connecting rod is fixed on the adjusting arm. One end of the telescopic cylinder is hinged to the connecting rod, and the other end of the telescopic cylinder is hinged to the movable frame.

[0019] The beneficial effects of this utility model are as follows: The transmission principle of this utility model is basically the same as that of the prior art. It utilizes the cooperation of an eccentric shaft and an eccentric sleeve. When the eccentric shaft rotates, the eccentric sleeve drives the movable frame to move back and forth in the left and right directions, thereby realizing the horizontal rhythm of the furniture. Unlike the prior art, the eccentric sleeve in this utility model has an inner hole and an outer circumferential surface that is eccentrically set with respect to the inner hole. When it is necessary to adjust the horizontal rhythm amplitude of the furniture, the eccentric sleeve is rotated relative to the movable frame through the angle adjustment mechanism, so that the eccentricity between the eccentric shaft and the eccentric sleeve changes, thereby causing a change in the rhythm amplitude.

[0027] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0029] An embodiment of this utility model of a variable amplitude horizontal rhythmic furniture is as follows: Figures 1-5 As shown: The horizontal rhythmic furniture in this embodiment is a horizontal rhythmic bed (or a horizontal rhythmic sofa).

[0030] The horizontally movable furniture includes a fixed frame 5, on which a movable frame is mounted for lateral movement. A drive mechanism is provided between the fixed frame and the movable frame to drive the movable frame to reciprocate in the lateral direction. In this embodiment, the movable frame includes a left crossbeam 1 extending in the front-back direction and a right crossbeam 14 extending in the front-back direction. Two left guide rods 4 extending in the left-back direction are fixed on the left crossbeam, and two right guide rods 13 extending in the left-back direction are fixed on the right crossbeam. The two left guide rods are spaced apart front-back, and the two right guide rods are spaced apart front-back. The left ends of the two left guide rods are fixed to the left crossbeam, and the right ends of the two right guide rods are fixed to the right crossbeam.

[0031] The fixed frame is equipped with a guide mechanism that guides the movable frame in the left-right direction. The guide mechanism includes guide wheel sets 2, each corresponding to a guide rod. Each guide wheel set includes a wheel set bracket 3. Two lower rollers, arranged left and right, are rotatably mounted on the wheel set bracket. An upper roller, located above the lower rollers, is also rotatably mounted on the wheel set bracket. Each guide rod is positioned between the upper roller and the two lower rollers of its corresponding guide wheel set. The two lower rollers and one upper roller are arranged in a triangular pattern, meaning that the lower end of the guide rod is in rolling contact with the two lower rollers, and the upper end of the guide rod is in rolling contact with the upper roller.

[0032] The drive mechanism includes an eccentric shaft 16 with its rotation axis extending in the front-rear direction and rotatably mounted on a fixed frame. A bearing bracket is mounted on the fixed frame, and both ends of the eccentric shaft are rotatably engaged with the bearing bracket via end bearings. The eccentric shaft is driven to rotate by a drive motor 6; specifically, the motor shaft of the drive motor 6 is connected to the eccentric shaft via a transmission belt. The drive mechanism also includes an eccentric sleeve 7 with its rotation axis extending in the front-rear direction and rotatably mounted on a movable frame. The eccentric sleeve has an inner hole and an outer circumferential surface eccentrically positioned relative to the inner hole. The outer circumferential surface of the eccentric sleeve is rotatably engaged with the movable frame via an outer bearing 17. Specifically, a transmission frame 11 is mounted on the movable frame, and an eccentric sleeve support 9 is fixedly mounted on the transmission frame 11. The eccentric sleeve is rotatably engaged with the eccentric sleeve support 9 via the outer bearing 17. An inner bearing 12 is mounted on the inner wall of the eccentric sleeve, and the eccentric shaft has an eccentric portion that engages with the inner bearing for force transmission. An angle adjustment mechanism is mounted on the transmission frame for adjusting the rotation angle of the eccentric sleeve relative to the movable frame.

[0033] The angle adjustment mechanism includes a telescopic cylinder 10 mounted on the transmission frame. One end of the telescopic cylinder 10 is connected to the transmission frame 11, and the other end of the telescopic cylinder 10 is connected to the eccentric sleeve. In this embodiment, the telescopic cylinder is an electric telescopic cylinder. An adjusting arm 8 is fixed to the eccentric sleeve by bolts, and a connecting rod 15 is fixed to the adjusting arm. One end of the telescopic cylinder 10 is hinged to the connecting rod 15, and the other end of the telescopic cylinder 10 is hinged to the movable frame 11.

[0034] In operation, the drive motor drives the eccentric shaft to rotate around its own axis via a transmission belt. The eccentric part of the eccentric shaft pushes against the inner ring of the inner bearing, thus moving the eccentric sleeve. The eccentric sleeve, along with the movable frame, moves back and forth in the left and right directions, achieving a certain amplitude of horizontal rhythmic movement. The output speed of the drive motor can be changed to adjust the rhythmic frequency. When the rhythmic amplitude needs to be adjusted, the telescopic cylinder activates, causing the adjusting arm to rotate the eccentric sleeve. This changes the eccentricity between the eccentric sleeve and the eccentric shaft, thereby altering the rhythmic amplitude and meeting various rhythmic amplitude requirements.
