Description

Technical Field

[0001] The invention relates to a control method and a device thereof, and in particular to a calf unit translation type seat giving way control method and a mechanism thereof. Background Art

[0002] The calf units in massage chairs usually include electric rollers or air bags, which can simulate the kneading, tapping and squeezing of the calf by human hands. These units can automatically wrap the user's calf according to the user's calf size to adapt to different leg shapes. The electric roller moves along the contour of the calf to provide acupressure and massage effects, while the air bag simulates squeezing massage by inflating and deflating, promoting blood circulation in the legs and relieving muscle fatigue. Some advanced massage chairs may also include a heat compress function to further enhance the relaxation effect.

[0003] Chinese patent document CN208464566U discloses a massage chair, including a chair frame mechanism, which includes a backrest frame and a base frame assembly, and also includes a supporting round rod and a support plate. The base frame assembly includes a base frame, a backrest electric push rod, a linear guide and a sliding frame, the linear guide is installed on the base frame, one end of the backrest electric push rod is fixedly connected to the base frame, and the other end of the backrest electric push rod is connected to the sliding frame and can drive the sliding frame to reciprocate horizontally along the extension direction of the linear guide, and the two sides of the front section of the backrest frame are respectively hingedly connected to the two sides of the sliding frame through the support plate; the supporting round rod is arranged on the rear side of the support plate, and the two ends of the supporting round rod are respectively hingedly connected to the backrest frame and the base frame. It also includes a calf assembly and a linkage assembly. One end of the back of the calf assembly is movably connected to the front end of the backrest frame. The linkage assembly includes a calf electric push rod, a linkage rod and a support wheel. One end of the linkage rod is hingedly connected to the front end of the bottom of the backrest frame, and the support wheel is movably connected to the other end of the linkage rod. The support wheel always contacts the back of the calf assembly. The two ends of the calf electric push rod are respectively hingedly connected to the support plate and the linkage rod.

[0004] The above scheme realizes the lifting and lowering of the calf component through the linkage component, so that the user can enjoy the service of the massage chair in a lying position. However, the above scheme has the following shortcomings: after completing the massage action, although the calf component can be lowered to a position close to the ground, it is still at a certain distance from the ground, and because the user's calf is embedded in the calf component, it is necessary to support the armrest with the arm to lift the body before walking out of the massage chair; similarly, when the user enters the massage chair, it is also necessary to support the armrest with the arm to lift the lower part of the body before entering the massage chair. The above action will cause trouble for young people who are strong and healthy, and it will make it completely impossible for the elderly who are entering their twilight years to use the massage chair. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a calf unit translation type seating control method which is more convenient for users to sit in or leave a seat.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a calf unit translation type seat-giving control method, comprising a calf unit composed of a leg assembly and a foot assembly, the calf unit comprising a working state, an initial state and a seat-giving state, and the process of the calf unit returning from the working state to the initial state is as follows: S1, the leg assembly maintains the working position, and the foot assembly moves to the initial state first; S2, the foot assembly is in an initial state and then translates to a yielding state; S3, the leg assembly moves to the initial state after the foot assembly is in the yielding state.

[0007] Furthermore, the foot component moves from the initial state toward the yielding state in a direction away from the leg component until it does not interfere with the leg component.

[0008] Furthermore, the leg assembly is provided with a massage groove for placing the human leg, and the massage groove at least exceeds the knee position along the extension direction of the human leg.

[0009] It should be noted that the reverse process can be naturally inferred from the above scheme, that is, the operation process of the leg unit when the user enters the massage chair. First, the foot component is in a yielding state. After the user's legs are placed in the leg component, the foot component moves from the yielding state to the initial state and then turns to the working state. The movement of the foot component until it does not interfere with the leg component means that after it moves, there is no foot component within the distance formed by the two massage grooves compared to the two side edges of the outer side of the human leg projected on the ground. At this time, it will not affect the user's sitting or leaving the massage chair, and the above movement can be either a one-way movement or a movement between the foot components.

[0010] The beneficial effects of the calf unit translational giving way and sitting control method of the present invention are as follows: first, the control method restores the calf unit to its initial state in steps, first allowing the foot component to move to the initial state, then translation to the giving way state, and finally the leg component to move to the initial state. This step-by-step control can adjust the state of the massage chair more smoothly, reduce the user's discomfort when sitting in and out of the seat, and enable the user to sit in and out of the seat without having to support the body with the arms, effectively improving the user experience.

[0011] Secondly, the foot component moves to the initial state first, and then moves horizontally to the yielding state. This design allows the foot component to be adjusted without interfering with the leg component. This design optimizes space utilization, allowing the massage chair to provide more flexible leg and foot position adjustment in a limited space to adapt to the leg length and shape of different users.

[0012] In addition, by gradually adjusting the positions of the foot and leg components, the control method reduces the potential safety hazards caused by rapid mechanical movement. In particular, after the foot component moves to the initial state first, it translates to the yielding state, and during this process the leg component always remains in the working state. This separate movement can not only prevent the foot component from accidentally squeezing or impacting the user's legs during movement, but also enhance the safety of the massage chair and improve the user's experience when sitting and leaving the seat.

[0013] Furthermore, the massage groove design on the leg component allows the leg component to cover the position below the knee. This design helps to avoid the user's legs needing to exert their own strength to keep suspended in the air when the foot component moves from a working state to a yielding state, further improving the user experience.

[0014] Finally, the yielding state design of the foot assembly allows the foot assembly to be set on the same side as the end face of the leg assembly in the working state and the yielding state, and allows sufficient misalignment between the foot assembly and the leg assembly to prevent the position of the foot assembly from interfering with the position of the user entering and leaving the seat.

[0015] The present invention also provides a calf unit translational seating control mechanism for realizing the above-mentioned calf unit translational seating control method, and its technical scheme is as follows: it includes a massage chair body, a calf unit composed of a leg assembly and a foot assembly, and a lifting assembly for controlling the lifting and lowering of the leg unit. The leg assembly and the foot assembly are respectively provided with a leg lifting assembly and a foot lifting assembly for controlling the independent lifting and lowering of the above two assemblies relative to the rear side of the human body's legs. The leg assembly includes a leg flip plate hinged on the massage chair body and a leg massage piece fixed on the leg flip plate. The foot assembly includes a foot flip plate hinged on the leg flip plate and a foot massage piece fixed on the foot flip plate. A translation driving member for driving the foot flip plate to translate is provided between the leg flip plate and the foot flip plate.

[0016] Furthermore, the leg flip plate and the foot flip plate are respectively provided with a leg thrust plate and a foot thrust plate facing the direction of the massage chair, and the leg lifting assembly and the foot lifting assembly are respectively against the leg thrust plate and the foot thrust plate and respectively drive the leg flip plate and the foot flip plate to rotate.

[0017] Furthermore, the foot flip plate is provided with two hinged tubes, and both sides of the leg flip plate are provided with rotation holes for the hinged tubes to be sleeved and for the hinged tubes to rotate therein.

[0018] Furthermore, the leg flip plate is provided with a fixed tube located between the two hinged tubes, and the two hinged tubes are each provided with a translational drive member connected to the fixed tube and driving the foot flip plate away from or approaching the fixed tube, and one end of the translational drive member fixed in the fixed tube can rotate in the fixed tube.

[0019] The beneficial effects of the calf unit translational seat-taking control mechanism of the present invention are: the above scheme can realize the independent movement of the leg assembly and the foot assembly without affecting the normal operation of the massage chair, and can realize the switching of the leg assembly and the foot assembly between various states.

DETAILED DESCRIPTION

[0021] A method for controlling the translational seat-taking of a lower leg unit according to an embodiment of the present invention is as follows: Figure 1 As shown, the calf unit 1 is composed of a leg component 2 and a foot component 3. The calf unit 1 includes a working state, an initial state and a yielding state. The yielding state of the foot component 3 means that when the foot component 3 is in the working state, one of the end faces on the same side as the leg component 2 is located on the same side as the other end face of the leg component 2 when it is in the yielding state. The leg component 2 is provided with a massage groove 211 for placing the human leg, and the massage groove 211 at least exceeds the knee position in the extension direction of the human leg. The above control method is implemented according to the following steps, which is the flow of the control method in this embodiment when the user leaves the seat: S1, the leg assembly 2 maintains the working position, and the foot assembly 3 moves to the initial state first; S2, the foot component 3 is in the initial state and then moves to the yielding state; S3, the leg component 2 moves to the initial state after the foot component 3 is in the yielding state.

[0022] The reverse workflow, i.e. the workflow when the user takes a seat, is as follows: first, the foot component 3 is in a yielding state. After the user's legs are placed in the massage grooves 211 of the leg component 2, the foot component 3 moves from the yielding state to the initial state and then to the working state.

[0023] The present invention provides a calf unit translation type seat-taking control mechanism as shown in the following example. Figure 2-5 As shown: it includes a massage chair body 4, a calf unit 1 composed of a leg component 2 and a foot component 3, and a leg lifting component 5 and a foot lifting component 6 for respectively controlling the lifting and lowering of the leg component 2 and the foot component 3 and being arranged farther away from the human body than the leg component 2 and the foot component 3.

[0024] The leg assembly 2 includes a leg flip plate 22 hinged on the massage chair body 4 and a leg massage piece 21 fixed on the leg flip plate 22, a massage groove 211 is provided on the leg massage piece 21 and the massage groove 211 at least exceeds the knee position along the extension direction of the human leg; the foot assembly 3 includes a foot flip plate 32 hinged on the leg flip plate 22 and a foot massage piece 31 fixed on the foot flip plate 32.

[0025] A fixed tube 221 is hingedly connected to the leg flip plate 22, and both ends of the fixed tube 221 are hinged tubes 321 of the foot flip plate 32, and a translation driving member 7 is arranged in each hinged tube 321, one end of which is fixed in the fixed tube 221. A fixing hole 2211 with a T-shaped cross section is formed in the fixed tube 221, and the translation driving member 7 is a telescopic cylinder, and the shape of one end of the cylinder located in the fixed tube 221 is adapted to the fixing hole 2211.

[0026] The foot assembly 3 includes two groups of foot massage parts 31 that are independent of each other and a foot flip plate 32 for driving the foot massage parts 31 to move. A foot thrust plate 322 is arranged on the fixed tube 221. The foot lifting assembly 6 acts on the foot thrust plate 322 to drive the foot assembly 3 to rotate. The foot lifting assembly 6 includes a telescopic cylinder 61 and a roller 62 arranged on the top of the telescopic cylinder. How the leg lifting assembly 5 pushes the leg thrust plate 23 to drive the leg flip plate 22 to rotate belongs to the prior art and will not be elaborated here. As a preferred embodiment, the angle between the telescopic cylinder in the leg lifting assembly 5 and the ground is greater than the angle between the telescopic cylinder 61 in the foot lifting assembly 6 and the ground, and when the foot assembly 3 is in the initial state, the roller 62 in the foot lifting assembly 6 abuts against the top of the foot thrust plate 322, that is, the end closest to the fixed tube 221.

[0027] The use process of this embodiment is as follows: The movement of the leg assembly 2 of this embodiment belongs to the prior art and will not be described in detail here. When the foot assembly 3 rotates, the translation drive member 7 applies a torque to achieve a close fit with the fixed tube 221, so that when the foot lifting assembly 6 drives the fixed tube 221 to rotate by pushing the foot thrust plate 322, it can also drive the hinged tubes 321 located on both sides of the fixed tube 221 to rotate. As a preferred embodiment, the surfaces where the fixed tube 221 and the hinged tube 321 contact are respectively provided with positioning beads 2212 and positioning holes 3211 arranged in a semicircular arc to further synchronize the rotation of the fixed tube 221 and the hinged tube 221. When the foot assembly 3 moves from the initial state to the yielding state, the translation drive member 7 pushes the hinged tube 321 to move in a direction away from the fixed tube 221 until there is no foot massage member 31 within the range of the massage groove 221.

[0028] The above embodiment is only one of the preferred specific embodiments of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
