Description

[Technical field]

[0001] This utility model relates to the field of fitness equipment technology, specifically a massage chair that can be moved forward and backward to achieve zero wall contact. [Background Technology]

[0002] Currently, most conventional massage chairs on the market require a sufficient safety gap (50-500mm) between the chair back and the wall. The national standard GB-T 26182-2022 requires a minimum clearance of 80mm between the chair back and the wall to ensure the massage chair back does not hit the wall when the chair is reclined (see attached). Figure 1a and attached Figure 1b (As shown).

[0003] However, there is currently no massage chair on the market that moves forward or backward using a four-wheeled movement device, making it impossible to achieve complete zero-wall support. This means that sufficient safety space must be reserved when placing a massage chair in the home, thus wasting home space.

[0004] Therefore, if this gap can be filled and a massage chair that can be moved forward and backward to achieve zero wall contact can be provided, it will be of great significance that users do not need to consider the distance from the wall when placing the massage chair at home, and that it will not require much manpower or effort when moving and cleaning it. [Utility Model Content]

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a massage chair that can slide forward and backward to achieve zero wall contact. This solves the problem that traditional massage chairs cannot achieve complete zero wall contact, eliminating the need to reserve safety space when placing the massage chair at home and saving more space for the family.

[0006] To achieve the above objectives, a massage chair capable of forward and backward sliding to achieve zero wall contact is designed, comprising a massage chair body 11 and a chair frame 12 installed below the massage chair body 11. The bottom of the chair frame 12 is provided with a moving mechanism, which includes a drive wheel device 3 and a driven wheel 2. The drive wheel device 3 and the driven wheel 2 are arranged front and rear. The drive wheel device 3 includes a motor 4, a gearbox 5, a drive shaft 6, a bearing seat 7, and a drive wheel 8. The output end of the motor 4 is connected to the drive shaft 6 through the gearbox 5, and drives the drive shaft 6 to rotate forward and backward. Drive wheels 8 and bearing seats 7 are installed on both the left and right sides of the drive shaft 6. The bearing seats 7 are fixedly installed at the bottom of the chair frame 12. The drive wheels 8 rotate forward or return to their original position under the drive of the motor 4 and the drive shaft 6, thereby driving the chair frame 12 and the massage chair body 11 to move forward or backward.

[0007] Furthermore, the drive wheel device 3 is installed on the front / rear side of the bottom of the chair frame 12, and the driven wheel 2 is installed on the rear / front side of the bottom of the chair frame 12. The driven wheel 2 and the drive wheel 8 of the drive 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 drive wheel device 3 and the driven wheel 2 can be interchanged, they can be adjusted according to the specific placement requirements, making the use more flexible.

[0008] Furthermore, the bearing seat 7 is a rolling bearing or a plastic bushing, and the bearing seat 7 is symmetrically provided with mounting holes, which are then fixed to the bottom of the chair frame 12.

[0009] Furthermore, the drive shaft 6 passes through the gearbox 5, the bearing housing 7 is installed at both ends of the drive shaft 6, and the drive wheel 8 is installed inside the bearing housing 7.

[0010] Furthermore, a counting disk 9 is installed on the drive shaft 6. The counting disk 9 rotates with the rotation of the drive shaft 6. An optocoupler sensor 10 is installed on the counting disk 9, and the number of rotations of the drive shaft 6 is obtained through the optocoupler sensor 10.

[0011] Furthermore, the motor 4 is connected to the controller via a circuit and starts when the power switch of the controller is pressed, thereby driving the massage chair body 11 forward to a safe distance L; after the massage is finished, the motor 4 reverses when the power off button is pressed, thereby driving the massage chair body 11 backward by the same distance to return to its original position against the wall.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] (1) This utility model provides a structure that allows the massage chair to be completely free from wall support, thereby saving more placement space in the home;

[0014] (2) This utility model fully considers the different family needs for the space to place the massage chair and solves the problem of the structural limitations of ordinary massage chairs;

[0015] (3) This utility model fills the gap in the market for this function through a transmission mechanism, and is more user-friendly in design and saves more space in the home.

[0016] (4) This utility model has a lower cost and is more in line with market demand, which can promote the continuous development of massage chair technology;

[0017] (5) This utility model allows users to place a massage chair at home without having to consider the distance from the wall, and it also does not require much manpower or effort when moving and cleaning it.

[0018] In summary, this utility model provides a structure for a four-wheeled massage chair that allows for overall forward and backward translation, solving the problem that traditional massage chairs cannot achieve complete zero-wall placement. This structure enables complete zero-wall placement, eliminating the need to reserve safety space when placing the massage chair at home, and is worthy of widespread application.

[0033] This utility model provides a massage chair that can move forward and backward to achieve zero wall contact, including a massage chair body 11 and a chair frame 12 installed below the massage chair body 11. The bottom of the chair frame 12 is provided with a moving mechanism, which includes a drive wheel device 3 and a driven wheel 2. The drive wheel device 3 and the driven wheel 2 are arranged front and rear. The drive wheel device 3 includes a motor 4, a gearbox 5, a drive shaft 6, a bearing seat 7 and a drive wheel 8. The output end of the motor 4 is connected to the drive shaft 6 through the gearbox 5 and drives the drive shaft 6 to rotate forward and backward. Drive wheels 8 and bearing seats 7 are installed on both sides of the drive shaft 6. The bearing seats 7 are fixedly installed at the bottom of the chair frame 12. The drive wheels 8 rotate forward or return to their original position under the drive of the motor 4 and the drive shaft 6, thereby driving the chair frame 12 and the massage chair body 11 to move forward or backward.

[0034] The drive wheel assembly 3 is installed on the front / rear side of the bottom of the chair frame 12, and the driven wheel 2 is installed on the rear / front side of the bottom of the chair frame 12. The driven wheel 2 and the drive wheel 8 of the drive wheel assembly 3 are distributed at the four corners of the bottom of the chair frame 12. Since the front and rear positions of the drive wheel assembly 3 and the driven wheel 2 can be interchanged, they can be adjusted according to the specific placement requirements, making them more flexible to use. The bearing seat 7 uses a rolling bearing or a plastic bushing. The bearing seat 7 has symmetrical 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 drive shaft 6, which passes through the gearbox 5. The drive wheel 8 is installed inside the bearing seat 7.

[0035] A counting disk 9 is mounted on the drive shaft 6. The counting disk 9 rotates with the drive shaft 6. An optocoupler sensor 10 is mounted on the counting disk 9, and the number of rotations of the drive shaft 6 is obtained through the optocoupler sensor 10. The motor 4 is connected to the controller via a circuit and starts when the power switch of the controller is pressed, thereby driving the massage chair body 11 forward to a safe distance L. After the massage is finished, the motor 4 reverses when the power off button is pressed, thereby driving the massage chair body 11 backward by the same distance to return to its original position against the wall.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0037] As attached Figure 2 As shown, a traditional massage chair has four foot pads 1 in the front, back, left, and right, plus two driven wheels 2 at the rear.

[0038] As attached Figure 3As shown, this utility model removes the traditional four foot pads (front, back, left, and right), or only the two front foot pads, or only the two rear foot pads, and designs a drive wheel device 3 to work with the original driven wheel 2 to form a four-wheel movement structure. If the driven wheel 2 is on the front side, the drive wheel device 3 is installed on the rear side to form a four-wheel movement device (i.e., the positions are reversed).

[0039] As attached Figure 4a , Attachment Figure 4b , Attachment Figure 4c and appendix Figure 4d The diagram shows the installation of the bottom of the massage chair frame. The driven wheel 2 and the drive wheel device 3 form a four-wheel moving device, wherein the front and rear positions of the drive wheel 9 and the driven wheel 2 can be interchanged.

[0040] As attached Figure 5a and attached Figure 5b As shown, the drive wheel device 3 drives the drive shaft 6 to rotate forward and backward through the motor 4 and the gearbox 5 (which can be a single-stage or multi-stage transmission). The drive shaft 6 drives the drive wheel 8 to rotate forward or return to its original position through the bearing seat 7 (which can be a rolling bearing or a plastic bushing). The rotation of the drive 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.

[0041] Furthermore, the rotation of the drive shaft 6 can cause the counting disk 9 on the shaft to start rotating, and the number of shaft rotations can be calculated by the optocoupler sensor 10. Specifically, the following can be used: the number of holes in the counting disk 9 is X, the outer diameter of the roller of the counting disk 9 is R, then the movement amount for counting one number is: 2πR / X. According to the amount L that different massage chairs need to move forward, the amount of movement counting Y can be predetermined: Y=L / (2πR / X)=XL / 2πR.

[0042] As attached Figure 6a As shown, when placing the massage chair at home, no safety distance needs to be reserved between it and the wall. When the customer presses the power switch on the controller and starts the massage, the moving device is first controlled to move the massage chair forward to a certain safety distance L (the amount of movement L can be preset according to the actual reclining needs of the massage chair). Once it has moved to the position shown in the attached diagram... Figure 6b After maintaining a safe distance, lean back in your chair; as per attached Figure 6c As shown, the chair back will not collide with the wall when reclined, and then the massage function will begin. After the massage is complete, when the guest presses the power off button, the chair back must first be returned to the upright position (as shown in the attached image). Figure 6b Then, through this moving device, the motor reverses direction and moves the same distance L (as shown in the attached diagram). Figure 6a Finally, the massage chair was moved back to its original position against the wall.

[0043] This invention can also be set with a manual control function to facilitate guests to control the drive device to move forward and backward. This is used for controlling the massage chair when moving it manually, such as when cleaning the dust at the bottom of the massage chair or when moving it in a certain space, saving guests time and effort.

[0044] In summary, this invention features a transmission mechanism. The motor, through a gearbox, reduces speed and drives the drive shaft to rotate. The drive shaft, via a drive wheel, propels the massage chair forward on the ground. The distance the massage chair travels is determined by a walking counter signal on the transmission shaft. After reaching a preset distance, the chair reclines, a distance adjustable based on the required clearance between the reclining chair and the wall. This structure is applicable to all massage chairs. After the massage is complete, the chair back is retracted, and the motor reverses direction, traveling the same distance as before to return the massage chair to the wall. Furthermore, this device can be equipped with a manual movement function. This allows for convenient use during household cleaning. The massage chair can be moved forward, and once the designated area is clean, it can be manually moved back to the wall for storage. This makes it very convenient to use.
