DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a massage chair that is easy to move, including a massage chair body 1. The massage chair body 1 is a common electric massage chair in the prior art and will not be described in detail herein. A bottom plate 2 is fixed to the bottom of the massage chair body 1, and a walking structure is evenly fixed to the bottom of the bottom plate 2. The walking structure can support the massage chair, and the walking structure is used to facilitate the movement of the massage chair.

[0028] The above-mentioned walking structure includes a fixed plate 10, a wheel frame 14 and a walking wheel 9; the fixed plate 10 is fixedly connected to the bottom of the base plate 2, and the fixed plate 10 and the wheel frame 14 are connected through a brake structure 1, and the brake structure 1 includes an I-frame 16, an upper brake pad 15, a lower brake pad 8, a spring 12 and a first push rod 13.

[0029] The top of the I-shaped frame 16 is movably connected to the middle of the bottom of the inner cavity of the fixed plate 10, and the bottom of the I-shaped frame 16 is fixedly connected to the middle of the top of the wheel frame 14. Through the setting of the I-shaped frame 16, the wheel frame 14 can rotate along the axis of the vertical end of the I-shaped frame 16.

[0030] The upper brake pad 15 is fixedly connected to the outer ring of the vertical end of the I-shaped frame 16, and the upper brake pad 15 is located below the fixed plate 10. The lower brake pad 8 is movably connected to the outer ring of the vertical end of the I-shaped frame 16, and the lower brake pad 8 is located below the upper brake pad 15. The two ends of the top of the lower brake pad 8 are fixed with a spring 12 and a first push rod 13. The top of the spring 12 is fixedly connected to the bottom of the fixed plate 10, and the spring 12 is in a contracted state. Under the action of the rebound force of the spring 12, the lower brake pad 8 is tightly fitted with the upper brake pad 15. The friction between the lower brake pad 8 and the upper brake pad 15 makes the I-shaped frame 16 unable to rotate relative to the fixed plate 10, thereby fixing the position of the wheel frame 14. The first push rod 13 is in a state of movably connected with the fixed plate 10. When the first push rod 13 moves downward, the first push rod 13 can drive the lower brake pad 8 to move downward. When the lower brake pad 8 is separated from the upper brake pad 15, the I-shaped frame 16 can rotate relative to the fixed plate 10.

[0031] From the above description of brake structure 1, it can be seen that when the lower brake pad 8 contacts the upper brake pad 15, the position of the I-frame 16 can be fixed, and the brake structure 1 realizes braking; when the lower brake pad 8 separates from the upper brake pad 15, the I-frame 16 can rotate under the action of external force.

[0032] The wheel frame 14 and the traveling wheel 9 are connected through a brake structure 2. The wheel frame 14 is an inverted U-shaped structure. A brake structure 2 is provided in the middle of both sides of the bottom end of the wheel frame 14. The brake structure 2 includes a rotating rod 26, a first brake pad 25, a fixed shell 20, a fixed box 21, a spring 24, a second brake pad 22 and a second push rod 23.

[0033] The rotating rod 26 is movably connected to the inner side of the inner cavity at the bottom end of the wheel frame 14, the two rotating rods 26 are connected through the walking wheel 9, and the rotating rod 26 is fixedly connected to the middle part of the end of the walking wheel 9, and a first brake pad 25 is fixed to the end of the rotating rod 26 away from the walking wheel 9, and the first brake pad 25 is movably connected to the inner cavity at the bottom end of the wheel frame 14, and the rotating rod 26 can rotate in the inner cavity at the bottom end of the wheel frame 14. When the rotating rod 26 rotates, it can drive the walking wheel 9 to rotate, thereby allowing the position of the massage chair body 1 to move.

[0034] The fixed shell 20 is threadedly connected to the outer side of the inner cavity at the bottom end of the wheel frame 14, and a fixed box 21 is movably connected to the inner cavity of the fixed shell 20. A second brake pad 22 is connected to the inner cavity of the fixed box 21 through a spring 24. The second brake pad 22 is movably connected to the inner cavity of the fixed box 21, and the second brake pad 22 is a convex structure. The outer diameter of one end of the second brake pad 22 away from the spring 24 is smaller than the outer diameter of the other end. The outer diameter of one end of the second brake pad 22 away from the spring 24 is the same as the outer diameter of the first brake pad 25, and one end of the second brake pad 22 away from the spring 24 is located outside the fixed box 21, and the spring 24 is in a contracted state. Under the action of the rebound force of the spring 24, the second brake pad 22 and the first brake pad 25 can fit tightly, restricting the rotation of the rotating rod 26, and the walking wheel 9 is in a braking state.

[0035] A second push rod 23 is fixed to the end of the second brake pad 22 away from the second spring 24. The second push rod 23 is L-shaped and is in an movably connected state with the wheel frame 14. The second brake pad 22 is located between the horizontal end of the second push rod 23 and the second spring 24. Therefore, when the horizontal end of the second push rod 23 moves toward the second spring 24 under the action of external force, the second push rod 23 can drive the second brake pad 22 to separate from the first brake pad 25, thereby releasing the braking state of the walking wheel 9.

[0036] The present application utilizes compressed air to drive the first push rod 13 or the second push rod 23 to move.

[0037] An air compressor 3 is fixed in the middle of the bottom of the base plate 2, and the air outlet end of the air compressor 3 is connected to the first air supply pipe 5 through the one-way valve 4. The compressed air generated by the air compressor 3 can enter the first air supply pipe 5 through the one-way valve 4. An exhaust pipe 6 is fixed to one end of the first air supply pipe 5 close to the one-way valve 4, and an electric exhaust valve 7 is provided on the exhaust pipe 6. Through the setting of the electric exhaust valve 7 and the exhaust pipe 6, when the exhaust pipe 6 is in an open state, the compressed air in the first air supply pipe 5 can be discharged.

[0038] An inverted mountain-shaped groove 18 is provided at the top of the inner cavity of the fixed plate 10, and the inner cavity of the inverted mountain-shaped groove 18 is connected to the inner cavity of the first air supply pipe 5 through a connecting pipe 11. The compressed air in the first air supply pipe 5 can enter the inner cavity of the inverted mountain-shaped groove 18 through the connecting pipe 11; the inner cavities at both ends of the inverted mountain-shaped groove 18 are movably connected with the first push rod 13, and the compressed air in the inverted mountain-shaped groove 18 can squeeze the first push rod 13. Under the action of the compressed air, the lower brake pad 8 and the upper brake pad 15 can be separated.

[0039] A second air supply pipe 19 is embedded in the middle of the bottom of the inverted mountain-shaped groove 18, a through hole is provided in the middle of the I-shaped frame 16, the bottom end of the second air supply pipe 19 is movably connected to the top of the inner cavity of the through hole, an air duct 17 is provided on the wheel frame 14, the bottom of the through hole is in contact with the top of the air duct 17, and the horizontal end of the second push rod 23 is movably connected to the inner cavity of the air duct 17 away from the through hole; through the arrangement of the air duct 17, the through hole and the second air supply pipe 19, the compressed air in the inverted mountain-shaped groove 18 can enter the inner cavity of the air duct 17 and squeeze the second push rod 23, so that the second brake pad 22 is separated from the first brake pad 25.

[0040] From the above description, it can be seen that when the air compressor 3 is working, the walking wheels 9 and the I-frame 16 can be released from the braking state at the same time, which is convenient for the movement of the massage chair. When the compressed air in the first air supply pipe 5 is discharged, the walking wheels 9 and the I-frame 16 can be in the braking state at the same time. The massage chair is supported by the walking structure, which is convenient for the use of the massage chair.

[0041] The outer surface of the first push rod 13 and the outer surface of the horizontal end of the second push rod 23 are both wrapped with a sealing sleeve, the material of the sealing sleeve can be rubber. Through the setting of the sealing sleeve, the sealing performance between the first push rod 13 and the inverted mountain-shaped groove 18 can be increased. The sealing sleeve can be used to increase the sealing performance between the second push rod 23 and the air duct 17, so that compressed air can push the first push rod 13 or the second push rod 23 to move.

[0042] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0043] To sum up: during normal use of the mobile massage chair, under the action of the rebound force of spring 12, the lower brake pad 8 fits tightly with the upper brake pad 15, and the friction between the lower brake pad 8 and the upper brake pad 15 fixes the position of the I-beam 16, thereby fixing the position of the wheel frame 14; under the action of the rebound force of spring 24, the first brake pad 25 fits tightly with the second brake pad 22, and the friction between the first brake pad 25 and the second brake pad 22 fixes the position of the walking wheel 9; the walking structure is in a braking state, and the walking structure supports the massage chair, so that the massage chair can work normally.

[0044] When the massage chair needs to be moved, the air compressor 3 works, and the compressed air generated by the air compressor 3 when working enters into the inverted mountain-shaped groove 18 through the first air supply pipe 5 and the connecting pipe 11. The compressed air in the inverted mountain-shaped groove 18 pushes the first push rod 13 to move downward, and the compressed air in the inverted mountain-shaped groove 18 enters into the air duct 17 through the second air supply pipe 19 and the through hole. The compressed air in the air duct 17 pushes the second push rod 23 away from the first brake pad 25. The first brake pad 25 and the upper brake pad 15 can release the braking state at the same time. Under the action of external force, the walking structure can move, which is convenient for the movement of the massage chair.
