Description

Technical Field

[0001] The utility model relates to a novel massage pad structure and belongs to the technical field of massage devices. Background Art

[0002] The massage chair in the cinema is a facility that combines movie watching and relaxation, aiming to provide the audience with a more comfortable movie watching experience. These massage chairs usually have multiple massage functions to relieve the audience's fatigue and stress while watching movies.

[0003] At present, most massage chairs are equipped with massage cushions to massage the audience's back. However, if the audience does not need massage, the massage cushion may hit the back when not in use. Therefore, in the prior art, a utility model patent with Chinese patent publication number CN218571799U discloses a massage cushion with a parking position for use in theaters. The massage movement can move along a track. When massage is not needed, the massage movement leaves the back area to achieve the effect of no hard objects on the backrest, so as to improve comfort and provide a better user experience.

[0004] Such massage cushions that can move are usually equipped with corresponding conductive rails to electrically connect the external control components to the massage cushion. The utility model patent with Chinese patent publication number CN215081807U discloses a flexible sliding control component and a massage cushion, including a flexible conductive rail, a sliding conductive component, and a cushion body mounted on the flexible conductive rail. When the cushion body slides along the flexible conductive rail, the metal probe in the sliding conductive component can make sliding contact with the conductive strip embedded on the flexible conductive rail to electrically connect the circuit board to the conductive strip, so as to facilitate the subsequent signal control work and power supply work.

[0005] The way to control the moving direction of this type of massage cushion that can walk is mostly to set a special movement board in the massage cushion, and then issue corresponding instructions to the movement board, so that the movement board controls the driving mechanism installed in the massage cushion and used to drive the massage cushion to slide to change the working state according to the instructions, so as to change the sliding direction of the massage cushion. For example, the technical solution of the above-mentioned utility model patent for a massage cushion with a parking position for a theater is to control the forward and reverse rotation of the drive motor by setting a movement board to change the moving direction of the massage movement. For example, the above-mentioned flexible sliding control part and massage cushion, it is to send instructions through a mobile phone or controller, and the instructions are transmitted to the MCU through the conductive strip. The MCU controls the massage movement to perform specified actions according to the instructions, such as sliding to the corresponding position along the flexible conductive track.

[0006] However, in the above scheme, when the metal probe and the embedded conductive strip are in sliding contact, the contact area is small, which easily leads to unstable contact, thereby causing the power supply to the massage cushion to be disconnected. At the same time, since a dedicated movement board is required on the massage cushion to control the forward and reverse rotation of the drive motor, when the power supply to the massage cushion is disconnected, the power supply of the dedicated movement board set on the massage cushion will also be disconnected, which will cause the massage data on the dedicated movement board to be lost, thereby affecting the subsequent massage work.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example: Please refer to Figures 1 to 5The present embodiment provides a novel massage pad structure, including two rack guides 1 and a massage movement 2, the two rack guides 1 are symmetrically arranged, and the massage movement 2 is arranged between the two rack guides 1. A driving mechanism 3 is arranged on the massage movement 2, and the driving mechanism 3 is meshed and connected with the two rack guides 1. The corresponding side ends of the two rack guides 1 are connected by setting a connecting strip a to form an integral structure, so as to facilitate subsequent installation work. A placement groove 4 is opened on the top surface of the two rack guides 1, and the layout direction of the placement groove 4 is adapted to the length direction of the rack guide 1. A conductive wire 5 is arranged in each placement groove 4, and the layout direction of the conductive wire 5 is adapted to the length direction of the corresponding placement groove 4. The specific shape of the conductive wire 5 can be selected and determined according to actual needs, such as a cylindrical shape for easy processing, or a flat shape to obtain a more stable contact.

[0029] The massage movement 2 is provided with an elastic metal pressing plate 6 which is in contact with two conductive wires 5 respectively. The elastic metal pressing plate 6 is made of elastic metal material. In the present embodiment, the elastic metal pressing plate 6 is a conductive elastic plate made of copper material. The elastic metal pressing plate 6 is arranged in a U-shaped structure. When the elastic metal pressing plate 6 is installed on the massage movement 2, it can be installed with the help of common connecting parts such as screws, or it can be installed in a common structural limit mode. The specific installation mode can be selected and determined according to the actual situation, and is not limited here. In the present embodiment, the elastic metal pressing plate 6 is installed with the massage movement 2 by using screws. The bottom surfaces of the two elastic metal pressing plates 6 are extended into the corresponding placement grooves 4. The bottom surfaces of the two elastic metal pressing plates 6 can be in close contact with the conductive wires 5 under pressure. The bottom surfaces of the two elastic metal pressing plates 6 are provided with convex arc portions 61. The number of arc portions 61 on the elastic metal pressing plate 6 can be determined according to the actual situation. In the present embodiment, two arc portions 61 are provided on the bottom surface of each elastic metal pressing plate 6. Each arc-shaped portion 61 is pressed against the conductive wire 5 at the corresponding position. The elastic metal pressing plate 6 is under pressure when the arc-shaped portion 61 is pressed against the conductive wire 5. The elastic metal pressing plate 6 can elastically deform itself to enable the arc-shaped portion 61 to be pressed against the conductive wire 5 in real time, thereby having a sufficient contact area with the conductive wire 5, thereby effectively avoiding the power supply disconnection of the massage movement 2. The two elastic metal pressing plates 6 are also electrically connected to the drive mechanism 3.

[0030] The massage cushion structure also includes a control component, which is arranged outside the massage cushion structure, such as being arranged in an external massage chair. The control component includes at least one external control circuit board, which is electrically connected to two conductive wires 5 and an external power supply. The control component, the two conductive wires 5, two elastic metal pressing plates 6 electrically connected to the two conductive wires 5, and the driving mechanism 3 form a circuit. The control component is used to control the current of the external power supply and provide the driving mechanism 3 with the current required for operation. The driving mechanism 3 reciprocates between the two rack guides 1 according to the change in the current flow direction on the two conductive wires 5, thereby driving the massage movement 2 to perform a corresponding movement between the two rack guides 1, so that there is no need to install a movement board on the massage movement 2. When the control circuit board is actually used, it can only realize the control of the current direction according to the needs, or it can integrate the current control and communication control.

[0031] Through the above-mentioned settings, there is no need to set up a special movement board and corresponding communication lines on the massage movement 2, so that the entire massage movement 2 can be made smaller, more convenient and more stable, reducing the production cost of the massage movement 2, and can also develop one less set of control programs, reducing the difficulty of development and improving maintainability; at the same time, only two conductive wires 5 are needed. Since the conductive wires 5 are moving to transmit electricity, there is a probability of disconnection in principle (the contact and the conductive wire 5 are disconnected for a short or long time without contact and electrical connection). Any disconnection of the conductive wire 5 will cause abnormal operation of the product. Assuming that the probability of disconnection of each conductive wire 5 is 10%, the probability of normal operation (no disconnection of the three wires) of the product with the utility model patent with Chinese patent publication number CN215081807U in the prior art is (1-10%) 3 =72.9%. If the power supply is disconnected, even if the contact is restored quickly, it will still cause the MCU program on the movement board to restart, thereby affecting the normal operation of the product (ending the massage in advance, etc.). The massage pad structure provided in this embodiment only needs two conductive wires 5. Because the number of conductive wires is reduced, assuming that the disconnection probability is 10%, the probability that the massage pad structure provided in this embodiment works normally (no disconnection occurs in the two conductive wires) is (1-10%). 2 =81%, which improves stability. Furthermore, if the power supply is temporarily disconnected, since there is no need to set a special movement board on the massage movement 2, it will not have a significant impact on its actual massage function. As long as the contact is restored, the driving mechanism 3 can immediately continue to operate normally.

[0032] In this embodiment, the driving mechanism 3 includes a double-headed motor 31 and two driving gear sets 32 corresponding to the two rack guide rails 1. The double-headed motor 31 is embedded on the top surface of the massage movement 2, and the double-headed motor 31 is installed between the two driving gear sets 32. The two elastic metal pressing plates 6 are electrically connected to the power supply end of the double-headed motor 31, so that when current is passed through the two conductive wires 5, the current can pass through the elastic metal pressing plates 6 to reach the double-headed motor 31, so as to provide the required working current for the double-headed motor 31. One end of the two driving gear sets 32 is meshed with the driving part at the corresponding position of the double-headed motor 31, and the other end of the two driving gear sets 32 is meshed with the rack guide rail 1 on the corresponding side.

[0033] Through the above-mentioned settings, when the massage pad structure needs to adjust the position of the massage movement 2, it starts working by starting the control component. The control component can output current to the two conductive wires 5 through electrical connection with the external power supply. The two conductive wires 5 cooperate with two elastic metal pressing plates 6 to form a circuit between the control component and the double-headed motor 31. The double-headed motor 31 can perform corresponding forward and reverse operations according to the flow direction of the current on the two conductive wires 5, thereby driving the two driving gear sets 32 to start working. The two driving gear sets 32 can drive the massage movement 2 to move along the two rack guides 1 by meshing with the two rack guides 1, thereby realizing the adjustment of the position of the massage movement 2. At the same time, by changing the direction of the current output by the control component, at this time, the direction of the current on the two conductive wires 5 is changed, and the direction of the double-headed motor 31 will change, so that the movement direction of the massage movement 2 on the two rack guides 1 can also be adjusted. Compared with the prior art, there is no need to set a dedicated movement board on the massage movement 2. The control component can change the direction of the output end of the double-headed motor 31 by changing the direction of the output current, thereby controlling the movement direction of the drive mechanism 3 and the massage movement 2. Even if the power supply to the massage movement 2 is disconnected later, because there is no dedicated movement board on the massage movement 2, the relevant massage data will not be lost.

[0034] Two connecting blocks 7 corresponding to the two rack guide rails 1 are installed on the left and right sides of the massage movement 2. The two connecting blocks 7 are arranged in a C-shaped structure. The tops of the two connecting blocks 7 are fixedly connected to the top surface of the massage movement 2. The two rack guide rails 1 are arranged to pass through the middle of the corresponding side connecting blocks 7. The upper walls of the bottoms of the two connecting blocks 7 are abutted against the bottom surfaces of the corresponding side rack guide rails 1. The middle inner side walls of the two connecting blocks 7 are abutted against the side walls of the corresponding side rack guide rails 1. Through the above-mentioned arrangement, the massage movement 2 can be stably installed on the two rack guide rails 1 with the help of the arrangement of the two connecting blocks 7, ensuring that the massage movement 2 is unlikely to fall off when moving along the two rack guide rails 1.

[0035] To ensure the stability of the massage movement 2 on the two rack guide rails 1. In this embodiment, the massage movement 2 is provided with a pair of first sliders 8 at the bottom close to the two side edges, and each pair of first sliders 8 has two sliders. The two first sliders 8 on the same side are slidably connected to the corresponding side placement groove 4, and the side walls of the two first sliders 8 on the same side that are away from each other are abutted against the two side groove walls of the corresponding side placement groove 4. At the same time, auxiliary grooves 9 are also provided on the two rack guide rails 1, and the massage movement 2 is provided with a second slider 10 at the bottom close to the two side edges, and the second sliders 10 on both sides are slidably matched to the corresponding side auxiliary grooves 9.

[0036] Through the above-mentioned settings, when the massage movement 2 moves on the rack guides 1 on both sides, the first slider 8 can slide in the placement groove 4, and the second slider 10 can slide in the auxiliary groove 9. The cooperation between the first slider 8 and the placement groove 4 and the cooperation between the second slider 10 and the auxiliary groove 9 can ensure that the massage movement 2 is unlikely to deviate left and right during the movement, thereby ensuring that the massage movement 2 is unlikely to fall off during the movement.

[0037] In order to control the position of the massage movement 2 on the two rack guides 1, the rack guides 1 and the massage movement 2 are both provided with positioning components for determining the position of the massage movement 2 on the rack guides 1. In the present embodiment, the positioning component includes a Hall sensor 11. The Hall sensor 11 is arranged at the two side end positions of one of the rack guides 1. The Hall sensors 11 on both sides are electrically connected to the control component. The control component can provide the Hall sensor 11 with the current required for its operation. Magnets 12 distributed front and back are provided in the massage movement 2. The magnets 12 on both sides are arranged close to the rack guides 1 here. The Hall sensors 11 on both sides can determine the position of the massage movement 2 by sensing the magnetic field strength generated by the corresponding side magnets 12, so as to facilitate the regulation of the position of the massage movement 2 during the subsequent massage process. At the same time, a threshold value can be set on the Hall sensor 11. When the Hall sensor 11 detects that the magnetic field strength exceeds the set threshold value, the Hall sensor 11 can send an electrical signal to the control component. After receiving the electrical signal, the control component can commutate the output current to change the movement direction of the massage movement 2. In this way, the movement range of the massage movement 2 on the rack guide 1 can be limited, thereby preventing the massage movement 2 from falling out of the rack guide 1.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
