Description

[Technical field]

[0001] The invention relates to the technical field of fitness equipment, in particular to a massage chair which can be translated forward and backward to achieve zero leaning against a wall. [Background Technology]

[0002] At present, conventional massage chairs on the market often require sufficient safety clearance (50-500mm) between the chair back and the wall. The national standard GB-T 26182-2022 requires a zero wall standard of 80mm to ensure that the chair back will not hit the wall when the massage chair is lying down (such as the attached Figure 1a and attached Figure 1b shown).

[0003] However, there is currently no massage chair on the market that can move forward or backward using a four-wheel moving device, and it is impossible to achieve complete zero leaning against the wall. This requires that sufficient safety space must be reserved when placing the massage chair at home, thus wasting the home placement space.

[0004] Therefore, it will be of great significance if this gap can be addressed and a massage chair that can be moved forward and backward to achieve zero wall contact can be provided, so that users do not need to consider the distance from the wall when placing the massage chair at home, and do not need to spend a lot of manpower when moving and cleaning. [Summary of the invention]

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a massage chair that can be translated forward and backward to achieve zero leaning against the wall, which solves the problem that traditional massage chairs cannot achieve complete zero leaning against the wall, so that when the massage chair is placed at home, it is no longer necessary to reserve a safe space, saving more placement space for the family.

[0006] In order to achieve the above-mentioned purpose, a massage chair that can be translated forward and backward to achieve zero leaning against the wall is designed, comprising a massage chair body 11 and a chair frame 12 installed under the massage chair body 11, a moving mechanism is arranged at the bottom of the chair frame 12, the moving mechanism includes a driving wheel device 3 and a driven wheel 2, the driving wheel device 3 and the driven wheel 2 are arranged front and back, the driving wheel device 3 includes a motor 4, a gearbox 5, a driving shaft 6, a bearing seat 7 and a driving wheel 8, the output end of the motor 4 is connected to the driving shaft 6 through the gearbox 5, and drives the driving shaft 6 to rotate forward and reverse, the driving shaft 6 is installed with a driving wheel 8 and a bearing seat 7 on both sides, the bearing seat 7 is fixedly installed at the bottom of the chair frame 12, the driving wheel 8 rotates forward or resets backward under the drive of the motor 4 and the driving shaft 6, thereby driving the chair frame 12 and the massage chair body 11 to move forward or backward.

[0007] Furthermore, the driving wheel device 3 is installed on the front side / rear side of the bottom of the chair frame 12, and the driven wheel 2 is installed on the rear side / front side of the bottom of the chair frame 12. The driven wheel 2 and the driving wheel 8 of the driving wheel device 3 are distributed at the four corners of the bottom of the chair frame 12. Since the front and rear positions of the driving wheel device 3 and the driven wheel 2 can be swapped, they can be adjusted according to the specific placement requirements, which is more flexible to use.

[0008] Furthermore, the bearing seat 7 adopts a rolling bearing or a plastic bushing, and mounting holes are symmetrically arranged on the bearing seat 7, and is fixed to the bottom of the chair frame 12 through the mounting holes.

[0009] Furthermore, the driving shaft 6 passes through the gearbox 5 , the bearing seat 7 is installed at the left and right ends of the driving shaft 6 , and the driving wheel 8 is installed on the inner side of the bearing seat 7 .

[0010] Furthermore, a counting disc 9 is installed on the driving shaft 6 , and the counting disc 9 rotates with the rotation of the driving shaft 6 . An optical coupling sensor 10 is installed on the counting disc 9 , and the number of rotations of the driving shaft 6 is calculated by the optical coupling sensor 10 .

[0011] Furthermore, the number of holes on the counting code disk 9 is X, and the outer diameter of the roller of the counting code disk 9 is R, then the movement amount of one count is 2πR / X. According to the safe distance L that different massage chairs need to move forward, the movement count amount Y can be predetermined: Y=L / 2πR / X=XL / 2πR.

[0012] Furthermore, the motor 4 is connected to the controller through a line, and is started after the power switch of the controller is pressed, thereby driving the massage chair body 11 to move forward to a safe distance L; after the massage of the massage chair body 11 is finished, the motor 4 reverses by pressing the power off button, thereby driving the massage chair body 11 to move backward the same distance to return to its position against the wall.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) The present invention provides a structure that enables the massage chair to be completely zero-walled, thereby saving more placement space for the family;

[0015] (2) The present invention fully considers the space requirements of different families for placing massage chairs, and solves the problem of structural limitations of ordinary massage chairs;

[0016] (3) The present invention fills the gap of this function in the market through a transmission mechanism, is more humane in design, and saves more space for household placement;

[0017] (4) The present invention has lower cost, is more in line with market demand, and can promote the continuous development of massage chair technology;

[0018] (5) The present invention allows users to place the massage chair at home without having to consider the distance from the wall, and does not require much effort when moving and cleaning the massage chair;

[0019] In summary, the present invention provides a structure in which a four-wheel massage chair can be translated forward and backward as a whole, which solves the problem that traditional massage chairs cannot achieve complete zero-wall proximity. Through this structure, complete zero-wall proximity can be achieved, so that the massage chair can be placed at home without reserving a safe space, and is worthy of promotion and application.

[0034] The present invention provides a massage chair that can be translated forward and backward to achieve zero leaning against the wall, comprising a massage chair body 11 and a chair frame 12 installed below the massage chair body 11, a moving mechanism is arranged at the bottom of the chair frame 12, the moving mechanism comprises a driving wheel device 3 and a driven wheel 2, the driving wheel device 3 and the driven wheel 2 are arranged front and back, the driving wheel device 3 comprises a motor 4, a gearbox 5, a driving shaft 6, a bearing seat 7 and a driving wheel 8, the output end of the motor 4 is connected to the driving shaft 6 through the gearbox 5, and drives the driving shaft 6 to rotate forward and reverse, the driving wheel 8 and the bearing seat 7 are installed on the left and right sides of the driving shaft 6, the bearing seat 7 is fixedly installed at the bottom of the chair frame 12, the driving wheel 8 rotates forward or resets backward under the drive of the motor 4 and the driving shaft 6, and then drives the chair frame 12 and the massage chair body 11 to move forward or backward.

[0035] The driving wheel device 3 is installed at the front / rear side of the bottom of the chair frame 12, the driven wheel 2 is installed at the rear / front side of the bottom of the chair frame 12, and the driven wheel 2 and the driving wheel 8 of the driving wheel device 3 are distributed at the four corners of the bottom of the chair frame 12. Since the front and rear positions of the driving wheel device 3 and the driven wheel 2 can be swapped, they can be adjusted according to the specific placement requirements, and the use is more flexible. The bearing seat 7 uses a rolling bearing or a plastic bushing, and the bearing seat 7 is symmetrically provided with mounting holes, and is fixed to the bottom of the chair frame 12 through the mounting holes; the bearing seat 7 is installed at the left and right ends of the driving shaft 6, the driving shaft 6 passes through the gearbox 5, and the driving wheel 8 is installed on the inner side of the bearing seat 7.

[0036] A counting disc 9 is installed on the driving shaft 6. The counting disc 9 rotates with the rotation of the driving shaft 6. An optical coupling sensor 10 is installed on the counting disc 9, and the number of rotations of the driving shaft 6 is calculated by the optical coupling sensor 10; the number of holes on the counting disc 9 is X, and the outer diameter of the roller of the counting disc 9 is R, then the movement amount of one count is 2πR / X, and according to the safe distance L that different massage chairs need to move forward, the movement count amount Y can be predetermined: Y=L / 2πR / X=XL / 2πR.

[0037] The motor 4 is connected to the controller through a line and starts after the power switch of the controller is pressed, thereby driving the massage chair body 11 to move forward to a safe distance L; after the massage of the massage chair body 11 is finished, the motor 4 reverses by pressing the power off button, thereby driving the massage chair body 11 to move backward the same distance to return to its position against the wall.

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0039] As attached Figure 2 As shown, the conventional massage chair is provided with four foot pads 1 at the front, back, left and right sides, plus two driven wheels 2 at the rear end.

[0040] As attached Figure 3 As shown, the present invention removes the four conventional foot pads, or only the two front foot pads, or only the two rear foot pads, and designs a driving wheel device 3 to cooperate with the original driven wheel 2 to form a front and rear four-wheel moving structure. If the driven wheel 2 is on the front side, the driving wheel device 3 is installed on the rear side to form a four-wheel moving device (i.e., the positions are reversed).

[0041] As attached Figure 4a , Attachment Figure 4b , Attachment Figure 4c And attached Figure 4d As shown, it is a schematic diagram of the installation at the bottom of the massage chair frame, in which the driven wheel 2 and the driving wheel device 3 form a four-wheel moving device, wherein the front and rear positions of the driving wheel 9 and the driven wheel 2 can be swapped.

[0042] As attached Figure 5a and attached Figure 5b As shown, the driving wheel device 3 drives the driving shaft 6 to rotate forward and reverse through the motor 4 and the gearbox 5 (which can be a single-stage transmission or a multi-stage transmission). The driving shaft 6 drives the driving wheel 8 to rotate forward or reset backward through the bearing seat 7 (which can be a rolling bearing or a plastic bushing). The rotation of the driving wheel 8 drives the entire chair frame to move forward and backward, thereby realizing the function of the massage chair being able to lean against the wall.

[0043] In addition, the rotation of the drive shaft 6 can drive the counting code disk 9 on the shaft to start rotating, and the number of shaft rotations can be calculated by the optical coupling sensor 10. Specifically, the number of holes in the code disk is X, and the outer diameter of the roller is R. The movement amount of one count is: 2πR / X. According to the amount L that different massage chairs need to move forward, the movement count amount Y is predetermined: Y=L / (2πR / X)=XL / 2πR.

[0044] As attached Figure 6a As shown, when the massage chair is placed at home, there is no need to reserve a safe distance from the wall; when the customer presses the power switch of the controller and starts the massage, the mobile device is first controlled to drive the massage chair to move forward to a certain safe distance L (the movement amount L can be pre-set according to the actual lying amount of the massage chair); when it moves to the attached Figure 6b After reaching a safe distance, tilt the seat back; if attached Figure 6c As shown, the chair back will not collide with the wall when it is lying down, and then start the massage function. After the massage structure, when the guest presses the off button, the chair back must first be reset to an upright state (as shown in the attached Figure 6b ), and then through this moving device, the motor reverses and moves the same distance L (as shown in the attached Figure 6a), and finally return the massage chair to the wall.

[0045] The present invention can also set a manual control function during control to facilitate guests to control the driving device to move forward and backward, which is used for controlling the normal manual movement of the massage chair, such as cleaning the dust at the bottom of the massage chair or translating when transporting it to a certain space, saving time and effort for guests.

[0046] In summary, the present invention is provided with a transmission mechanism, the motor is decelerated through the gearbox, drives the drive shaft to rotate, and then drives the massage chair forward on the ground through the drive wheel installed on the drive shaft; the position of the massage chair can be calculated by the walking count signal on the transmission shaft, and the distance the massage chair moves forward can be calculated. After walking to the preset distance, the backrest of the massage chair can be laid down, and this distance can be set according to the distance that different massage chairs need to reserve from the wall when lying down; this structure can be used on all massage chairs. After the massage is completed, the backrest is stored first, and then the motor is reversed to run the same distance as when moving forward, so as to return the massage chair to the wall. At the same time, the device can also be provided with a manual moving function, which is convenient for moving the massage chair forward through the manual moving function when cleaning the house, and after the massage chair is placed, the massage chair can be moved back to the wall for safekeeping through the manual moving function, which is very convenient to use.
