Description

Technical Field

[0001] The present invention relates to the technical field of massage chairs, and in particular to a massage device and a movement control method of a massage chair. Background Art

[0002] The massage chair is one of the common massage devices. The movement of the massage components in the chair can be found in the "A massage cushion with a parking position for theaters" disclosed in the announcement number CN218571799U. The massage movement drives the gear of the gear set to rotate on the rack through the drive motor, so that the massage movement can move along the track. However, the drive motor needs to be electrically connected to the power supply through wires, so that part of the wire moves with the massage movement, that is, there is a risk of the wire being entangled in the track. If the wire is entangled in the track, it is easy to cause the massage chair to not work normally, or the equipment to short-circuit. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a massage device and a movement control method for a massage chair, which can effectively ensure the massage operation of the massage chair without changing the movement mode of the massage components.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a massage device for a massage chair, comprising a massage bracket and a massage component; the massage bracket is provided with a guide rail arranged along its own length direction, and the guide rail is provided with a conductive strip along its own length direction; the massage component is slidably arranged on the guide rail, and the massage component is provided with a conductive thimble, and the conductive thimble is in contact with the conductive strip.

[0005] A method for controlling movement of a massage device of a massage chair, wherein when a neck massager moves in a neck massage section, a sensing module on the neck massager senses a trigger block, and the neck massager moves on a guide rail in a direction opposite to the current moving direction; When the waist and hip massager moves in the waist and hip massage section, when the sensing module on the waist and hip massager senses the trigger block, the waist and hip massager moves on the guide rail in the opposite direction of the current moving direction.

[0006] The beneficial effects of the present invention are as follows: a conductive strip is added to the guide rail, and a conductive pin in contact with the conductive strip is added to the massage component, so that the massage component can directly draw power from the guide rail to operate, thereby avoiding the wire being twisted into the guide rail, causing the massage chair to fail to operate normally or causing a short circuit in the equipment.

[0008] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0009] Please refer to Figures 1 to 3 As shown, a massage device of a massage chair of the present invention comprises a massage support 1 and a massage component 2; the massage support 1 is provided with a guide rail 3 arranged along its length direction, and the guide rail 3 is provided with a conductive strip 31 along its length direction; the massage component 2 is slidably arranged on the guide rail 3, and the massage component 2 is provided with a conductive thimble 21, which is in contact with the conductive strip 31.

[0010] Working principle: The conductive strip 31 is electrically connected to the power supply of the massage chair, so that the conductive strip 31 is charged, and the massage component 2 is in contact with the conductive strip 31 through the conductive pin 21, and the conductive strip 31 continuously provides power to the massage component 2.

[0011] In the first optional implementation, please refer to Figure 4 As shown, a mounting groove 34 is provided on the guide rail 3, and the conductive ejector pin 21 extends into the mounting groove 34 and contacts the conductive bar 31. The mounting groove 34 is used to limit the conductive ejector pin 21, so as to prevent the conductive ejector pin 21 from being separated when sliding on the surface of the conductive bar 31.

[0012] It is worth noting that the conductive strip 31 can be bonded in the assembly groove 34 by glue, or installed in the assembly groove 34 by welding.

[0013] In one implementation, please refer to Figure 1As shown, a rack 32 is provided on one side of the guide rail 3 away from the center of the massage bracket 1, and a driving assembly meshing with the rack 32 is provided on the massage component 2. The rack 32 is provided on one side of the guide rail 3 away from the center of the massage bracket 1, which can not only reduce the friction area between the bottom of the massage component 2 and the massage bracket 1 without changing the internal transmission structure of the massage component 2, but also free up space on one side end of the guide rail 3 close to the center of the massage bracket 1 for installing the conductive strip 31, so that the conductive strip 31 can be closer to the center position of the massage component 2, thereby facilitating the direct installation of the conductive ejector pin 21 on the housing of the massage component 2, so as to avoid increasing the housing volume of the massage component 2 for installing the conductive ejector pin 21.

[0014] In the second alternative implementation, please refer to Figure 2 and Figure 3 As shown, the driving assembly inside the massage assembly 2 includes a motor 24 and a gear set 25 , the output shaft of the motor 24 is transmission-connected to the gear set 25 , and the gear set 25 is transmission-connected to the rack 32 .

[0015] With respect to the above-mentioned second optional implementation, the massage block on the massage component 2 is transmission-connected to the gear set 25 .

[0016] In one implementation, please refer to Figure 1 As shown, the massage support 1 includes a waist and back support 11 and a buttocks support 12, and the massage component 2 reciprocates between the waist and back support 11 and the buttocks support 12 through the guide rail 3. The massage component 2 can move to the buttocks support 12 through the guide rail 3, thereby achieving massage of the buttocks of the human body.

[0017] In a third optional embodiment, the waist and back support 11 is made of elastic material so that the waist and back support 11 can be twisted to a certain extent, thereby allowing the waist and back support 11 to adapt to various sitting postures. The guide rail 3 is made of elastic material so that the guide rail 3 can extend to the hip support 12. At the same time, the conductive strip 31 is set as a flexible metal strip to ensure that the conductive strip 31 can always fit on the guide rail 3.

[0018] In a fourth optional embodiment, the waist and back support 11 is connected to the hip support 12 via a folding joint (not shown in the figure). The folding joint can be used to achieve the swinging of the waist and back support 11 on the hip support 12.

[0019] With regard to the folding joint in the fourth optional embodiment, such as the "L-shaped folding massage cushion" disclosed in the announcement number CN219847323U, the specification of the massage cushion states in paragraph

[0024] that the backrest bottom shell can be bent along the folding joint to be folded close to the seat cushion bottom shell, and the folding joint is composed of two connecting rods pivotally connected to each other, one connecting rod is fixed to the mounting groove of the seat cushion bottom shell by bolts, and the other connecting rod is fixed to the mounting groove of the backrest bottom shell by bolts, and the mounting grooves are correspondingly provided with assembly holes, so that the cushion can be folded by rotating the connecting rod between the seat cushion bottom shell and the backrest bottom shell, so that the angle of the seat can be better adjusted to facilitate the comfort of the user. The folding angle between the connecting rods is preferably 75° to 180°. When the connecting rod is opened, the backrest bottom shell and the seat cushion bottom shell are in an L-shaped structure. When the connecting rod is folded, the backrest bottom shell and the seat cushion bottom shell are closed to reduce the occupied space.

[0020] Regarding the folding joint in the fourth optional embodiment, such as the "A folding massage cushion" disclosed by announcement number CN219721223U, paragraph

[0023] of its specification records that the upper support frame and the lower support frame are connected together by a folding joint, and the soft rubber back shell can form a folded or unfolded state of the upper support frame and the lower support frame through the folding joint; the folding joint can adopt a foldable unit structure or a deformable structure. In the specific embodiment of the present application, the folding joint is composed of two fixed rods and a connecting rod, and the connecting rod is hinged with the fixed rods at both ends. Two mounting grooves are respectively provided on the upper support frame and the lower support frame, and the fixing rod is fixed to the corresponding mounting groove by bolts. The upper support frame and the lower support frame can be folded to an angle between 0° and 180° through the folding joint. When the upper support frame and the lower support frame are 0°, the massage cushion is in a fully unfolded state, and when the upper support frame and the lower support frame are 180°, the massage cushion is in a fully folded state.

[0021] In a fifth optional implementation, please refer to Figure 1 As shown, the massage assembly 2 includes a neck massager 22 and a waist and hip massager 23. The neck massager 22 reciprocates on the waist and back support 11 through the guide rail 3, and the waist and hip massager 23 reciprocates between the waist and back support 11 and the hip support 12 through the guide rail 3. The neck massager 22 massages the neck of the human body, and the waist and hip massager 23 performs a circular massage on the waist, back and hips of the human head, which can enhance the user experience.

[0022] In a sixth optional implementation, please refer to Figure 1 and Figure 5As shown, a plurality of trigger blocks 33 are arranged on the guide rail 3, and the trigger blocks 33 divide the guide rail 3 into a neck massage section and a waist and hip massage section. The neck massager 22 and the waist and hip massager 23 are provided with sensing modules for sensing the trigger blocks 33. Among them, the sensing module preferably adopts a Hall sensor, and the trigger block 33 is a magnetic block. The sensing module on the neck massager 22 controls the rotation direction of the output shaft of the motor 24 inside the neck massager 22 by magnetic induction, so that the neck massager 22 can only reciprocate in the neck massage section; the sensing module on the waist and hip massager 23 controls the rotation direction of the output shaft of the motor 24 inside the waist and hip massager 23 by magnetic induction, and the waist and hip massager 23 can only reciprocate in the waist and hip massage section.

[0023] In the fifth or sixth optional implementation, the massage device of the massage chair further includes a collision insurance (not shown in the figure), and the collision insurance has a first induction insurance respectively arranged on the neck massager 22 and a second induction insurance arranged on the waist and hip massager 23. When the neck massager 22 and the waist and hip massager 23 are approaching each other, the first induction insurance and the second induction insurance mutually sense the distance between the neck massager 22 and the waist and hip massager 23. If the distance between the neck massager 22 and the waist and hip massager 23 reaches a set threshold distance, the collision insurance will control the motor 24 inside the neck massager 22 or the waist and hip massager 23 to immediately reverse, so as to avoid the neck massager 22 and the waist and hip massager 23 from colliding.

[0024] Among them, since the waist and hip massager 23 has a large range of motion, preferably when the distance between the neck massager 22 and the waist and hip massager 23 reaches a set threshold distance, the collision insurance will control the motor 24 inside the waist and hip massager 23 to reverse immediately.

[0025] Specifically, the first induction fuse is a magnetic block, and the second induction fuse is a Hall sensor, which determines the distance between the neck massager 22 and the waist and hip massager 23 by magnetic induction.

[0026] In the seventh optional implementation, please refer to Figure 1 As shown, the hip support 12 is provided with air bags 121 at both ends along its width direction, and the air bags 121 and the hip support 12 are enclosed to form a leg clamping space. By circulating inflation and deflation inside the air bags 121, squeezing and massaging the side of the human thigh can be achieved.

[0027] Preferably, the airbag 121 is at least two inflatable bags with interconnected inner cavities. The airbag 121 is composed of multiple inflatable bags, which can reduce the volume of the inflated airbag 121 while satisfying the need for the airbag 121 to squeeze the side of the human thigh.

[0028] Taking the example of two inflatable bags with interconnected inner cavities constituting the airbag 121, the expansion coefficients of the two inflatable bags can be the same, and the expanded volumes of the two inflatable bags after inflation are similar. The expansion coefficients of the two inflatable bags can also be different, and specifically, the expanded volume of the inflatable bag near the center of the hip support 12 after inflation is larger than the expanded volume of the other inflatable bag.

[0029] With respect to the seventh optional implementation, the air injected into the airbag 121 may be cold air, hot air or room temperature air.
