Description

Technical Field

[0001] This application relates to the field of massage equipment technology, and more specifically, to a massage chair and a car. Background Technology

[0002] In existing technologies, the massage function of massage chairs is mostly achieved by installing the massage mechanism inside the seat back frame. After the massage function is activated, the massage mechanism drives the surface disc to rotate through the internal transmission to complete the massage. Some solutions will set an airbag under the massage head and use the airbag to fix the position and push out the massage.

[0003] However, these existing solutions have the following shortcomings: on the one hand, the massage techniques are monotonous and the massage intensity is weak, making it difficult to meet the diverse massage needs of users; on the other hand, the massage mechanism cannot move, limiting the massage position and making it impossible to adjust the massage angle and depth according to the curve of the human back, resulting in a narrow massage coverage area and poor fit, ultimately leading to a poor overall massage effect and a poor user experience. Utility Model Content

[0004] The purpose of this application is to provide a massage chair and car, which, through the cooperation of a fixed plate, a flexible guide rail, a pushing component and a massage mechanism, uses the pushing component to deform the flexible guide rail to drive the massage mechanism to move in the same direction, thereby solving the problems of existing solutions such as monotonous massage techniques, difficulty in moving the massage mechanism and poor fit, and improving the massage effect and user experience.

[0005] The embodiments of this application are implemented as follows: A first aspect of this application provides a massage chair, including a chair frame, a fixed plate and a flexible guide rail disposed on the chair frame, a pushing member disposed between the fixed plate and the flexible guide rail, and a massage mechanism disposed on the flexible guide rail. The pushing member is used to push the flexible guide rail to deform relative to the fixed plate, thereby driving the massage mechanism to move in the same direction as the pushing direction of the pushing member. This massage chair, through the cooperation of the fixed plate, flexible guide rail, pushing member, and massage mechanism, utilizes the pushing member to deform the flexible guide rail, thereby driving the massage mechanism to move in the same direction. This solves the problems of existing solutions such as limited massage techniques, difficulty in moving the massage mechanism, and poor fit, thus improving the massage effect and user experience.

[0006] As one possible implementation, a transmission plate is also included, which is disposed between the fixed plate and the flexible guide rail. The pushing member pushes the transmission plate to deform relative to the fixed plate, thereby causing the flexible guide rail to deform relative to the fixed plate.

[0007] In one possible implementation, there are two flexible guide rails, which are symmetrically arranged along the left and right sides of the chair frame, and the orthographic projection of the two flexible guide rails on the transmission plate falls on the surface of the transmission plate.

[0008] As one possible implementation, it also includes two crossbeams, which are arranged parallel to each other along the upper and lower sides of the chair frame, and the opposite ends of each crossbeam are respectively connected to the ends of the two flexible guide rails located on the same side of the massage mechanism.

[0009] As one possible implementation, it also includes two limit switches, which are respectively disposed on the two crossbeams to limit the movement of the massage mechanism along the extension direction of the flexible guide rail.

[0010] In one possible implementation, the massage mechanism includes a drive unit, a gear transmission assembly connected to the drive unit, and a massage head fixed on the rotating shaft of the gear transmission assembly. The flexible guide rail is provided with a flexible rack, and the end of the gear transmission assembly away from the drive unit meshes with the flexible rack.

[0011] In one possible implementation, the driving component is a drive motor with a double-headed worm gear, and there are two gear transmission groups and two massage heads. The two gear transmission groups are respectively connected to the double-headed worm gear of the drive motor, and the two massage heads are respectively arranged on the rotating shafts of the two gear transmission groups.

[0012] In one possible implementation, the gear transmission assembly includes a plurality of gears meshing sequentially, and the massage head is fixedly mounted on the shaft of one of the gears.

[0013] As one possible implementation, the number of the pushers is at least one; when the number of the pushers is multiple, the multiple pushers are spaced apart along the extension direction of the flexible guide rail; or, the pushers are airbags, thrust motors, or linkage structures.

[0014] A second aspect of this application provides an automobile that includes the aforementioned massage chair. This massage chair, through the cooperation of a fixed plate, a flexible guide rail, a pushing component, and a massage mechanism, utilizes the pushing component to deform the flexible guide rail, thereby driving the massage mechanism to move in the same direction. This solves the problems of existing solutions, such as limited massage techniques, difficulty in moving the massage mechanism, and poor fit, thus improving the massage effect and user experience.

[0015] The beneficial effects of the embodiments of this application include: This massage chair includes a chair frame, a fixed plate and a flexible guide rail mounted on the chair frame, a pushing component positioned between the fixed plate and the flexible guide rail, and a massage mechanism mounted on the flexible guide rail. The pushing component causes the flexible guide rail to deform relative to the fixed plate, thereby driving the massage mechanism to move in the same direction as the pushing component. This application utilizes the deformable characteristics of the flexible guide rail, combined with the directional pushing of the pushing component, to allow the flexible guide rail to bend into an arc shape consistent with the curvature of the human body. When the flexible guide rail deforms, the movement track on its surface drives the massage mechanism to move synchronously along the deformation trajectory. While moving with the flexible guide rail, the massage mechanism itself activates the massage head, forming a composite technique of "trajectory following + basic massage." This effectively solves the problems of existing solutions, such as limited massage techniques, immobile massage mechanisms, and poor fit. It significantly enriches the massage techniques, expands the massage coverage area, and improves the massage fit and intensity, thereby optimizing the massage effect and user experience.

[0022] Please refer to the reference. Figures 1 to 4 This application provides a massage chair 1, including a chair frame 11, a fixed plate 15 and a flexible guide rail disposed on the chair frame 11, a pushing member disposed between the fixed plate 15 and the flexible guide rail, and a massage mechanism 201 disposed on the flexible guide rail. The pushing member is used to push the flexible guide rail to deform relative to the fixed plate 15, so as to drive the massage mechanism 201 to move in the same direction as the pushing member. This massage chair 1, through the cooperation of the fixed plate 15, the flexible guide rail, the pushing member, and the massage mechanism 201, utilizes the pushing member to deform the flexible guide rail, thereby driving the massage mechanism 201 to move in the same direction. This solves the problems of existing solutions, such as limited massage techniques, difficulty in moving the massage mechanism 201, and poor fit, thus improving the massage effect and user experience.

[0023] It should be noted that the massage chair 1 includes a chair frame 11, a fixing plate 15, a pushing component, and a massage mechanism 2. Specifically, the massage mechanism 2 includes a flexible guide rail and a massage core 201. The chair frame 11 serves as the overall skeleton of the massage chair 1, providing a fixing reference for components such as the fixing plate 15 and the flexible guide rail, ensuring stability of each structure under stress, and is the load-bearing foundation of the device. The fixing plate 15 is a rigid support structure (such as a metal plate or a high-strength plastic plate) that can be fixed to the back, buttocks, or leg areas of the chair frame 11 (adapted to the massage area). The fixing plate 15 also serves as the fixing point for the pushing component. The fixed end support may have mounting grooves or positioning holes for the pusher to restrict the direction of movement of the pusher; the flexible guide rail is a guide carrier with deformable characteristics (such as high-strength elastic steel sheet or multi-layer composite flexible material guide rail), which is set parallel to the outside of the fixed plate 15 (i.e. the side closer to the user's body). Its length matches the massage area (such as the back guide rail covering the shoulders and neck to the waist). The surface may have sliding grooves or buckles for the massage mechanism 201 to provide a movement track for the massage mechanism 201. At the same time, it can bend and deform with external force, and can maintain a stable shape after deformation without rebounding.

[0024] The pusher, acting as a power output and deformation control unit (such as an electric push rod, a miniature cylinder, or a lead screw and slider assembly), can be arranged in multiples at intervals along the length of the fixed plate 15 (e.g., 3-5 evenly arranged on the back guide rail). Its fixed end is rigidly connected to the fixed plate 15, and its output end (such as the top of the push rod or the slider) contacts or is hinged to the inner side of the flexible guide rail (i.e., the side closest to the fixed plate 15). The pusher can apply a directional thrust to the flexible guide rail through telescopic or translational movements, forcing the flexible guide rail to bend and deform along the pushing direction (e.g., bulge upwards, dent downwards, or shift to the side). The massage mechanism 201 integrates the massage head 21 and the drive... The core actuator of the motor (such as a roller type or airbag type mechanism) can be connected to the outer side of the flexible guide rail (i.e., the side away from the fixed plate 15) through a slider or buckle, and can move along the length of the flexible guide rail. When the flexible guide rail deforms under the action of the pusher, the change in the trajectory of the flexible guide rail will drive the massage mechanism 201 to move synchronously. For example, when the flexible guide rail bulges upward, the massage mechanism 201 is pushed upward along the trajectory. When the flexible guide rail bends to fit the waist curve, the massage mechanism 201 fits the waist along the trajectory. At the same time, the massage head 21 of the massage mechanism 201 itself can perform basic massage actions such as kneading, pushing, and tapping.

[0025] The massage chair 1 also includes an electronic control system 102 electrically connected to the pushers and massage mechanism 201. After the user sits down, the electronic control system 102 controls the movement of the pushers in the corresponding areas according to the curves of the human body of the massage areas (such as the shoulders, neck, waist, and legs). For example, when massaging the waist, the pushers in the waist area extend and apply an outward pushing force to the flexible guide rail, causing the flexible guide rail to bend into an arc shape consistent with the physiological curvature of the waist. When the flexible guide rail deforms, the motion track on its surface drives the massage mechanism 201 to move synchronously along the deformation trajectory. When the flexible guide rail protrudes upward, the massage core 201 rises along the track, deeply massaging the waist muscles. When the flexible guide rail shifts to the side, the massage core 201 moves laterally along the track, covering a wider massage area. While moving with the flexible guide rail, the massage core 201 activates the massage head 21 (such as roller rotation and kneading, airbag inflation and deflation), forming a composite technique of "track following + basic massage" (such as massage along the shoulder and neck curve, and deep kneading that fits the waist), achieving more precise acupoint coverage and muscle relaxation.

[0026] Traditional massage chairs typically use massage mechanisms that move along fixed, rigid guide rails (such as straight lines or fixed arcs), allowing only unidirectional massage (like vertical up-and-down linear massage). The trajectory cannot be adjusted to suit individual needs, and the techniques are limited to basic movements like kneading and tapping. This application utilizes the deformable characteristics of flexible guide rails, combined with the directional pushing of the pushers, to generate various dynamic trajectories. For example, for the shoulders and neck, the upper pusher can be extended while the lower pusher retracts, creating a "convex upper, flat lower" trajectory on the flexible guide rail. This causes the massage mechanism 201 to lift and massage acupoints in the shoulders and neck. For the waist, the middle pusher can be extended, creating an "arc-shaped concave" trajectory on the flexible guide rail. This allows the massage mechanism 201 to conform to the waist curve for deep kneading. For the entire back, the pushers can be extended and retracted sequentially, creating a "wave-shaped" trajectory on the flexible guide rail. This allows the massage mechanism 201 to continuously roll and massage along the back curve, addressing the limitations of traditional massage techniques and meeting users' personalized needs for different areas and massage intensities.

[0027] Traditional rigid guide rails, with their fixed trajectories, cannot adapt to the different body shapes of users (e.g., the back curves of a 150cm and 190cm user are completely different), easily leading to problems such as the massage head 21 being suspended (e.g., without lumbar support) or excessive compression (e.g., excessive pressure on the shoulders and neck), resulting in poor fit and low comfort. The pusher provided in this application can adjust the deformation degree of the flexible guide rail according to the user's body shape data (e.g., by detecting the user's body contour through pressure sensors). For thinner users, the pusher extends less, and the flexible guide rail deforms gently; for heavier users, the pusher extends more, and the flexible guide rail deforms more significantly, ensuring that the massage core 201 always fits the body surface without being suspended or compressed. When the user adjusts their sitting posture (e.g., leaning forward or backward), the pressure sensor detects the change in body position, and the electronic control system 102 synchronously adjusts the movement of the pusher in the corresponding area, causing the flexible guide rail to re-deform with the posture change, keeping the massage core 201 in contact with the body. This avoids the fit failure caused by posture changes in traditional guide rails, greatly improving massage comfort and accuracy.

[0028] As one possible implementation method, such as Figure 2 and Figure 3 As shown, the massage chair 1 also includes a transmission plate 14, which is disposed between the fixed plate 15 and the flexible guide rail. The pusher pushes the transmission plate 14 to deform relative to the fixed plate 15, so as to drive the flexible guide rail to deform relative to the fixed plate 15.

[0029] It should be noted that the transmission plate 14 is a "force homogenization and transmission carrier" between the fixed plate 15 and the flexible guide rail. It can be made of a medium-rigidity elastic material (such as thin spring steel sheet or fiberglass reinforced composite board), and its length and width are perfectly matched with the flexible guide rail (e.g., the back transmission plate 14 covers the area from the shoulder and neck to the waist). The surface can have connection points along the length direction corresponding to the pusher and the flexible guide rail (e.g., lugs hinged to the output end of the pusher, protrusions bonded or snapped to the inner side of the flexible guide rail). The transmission plate 14 can bend under external force (e.g., protruding outward following the pusher's thrust), and at the same time, it can disperse the single-point thrust into a uniform force along the length direction of the flexible guide rail, avoiding uneven deformation of the flexible guide rail due to excessive local stress.

[0030] The electronic control system 102 controls the movement of the pusher (such as the extension of the electric push rod), and the output end of the pusher applies a directional thrust (such as an outward thrust) to the transmission plate 14. After receiving the thrust, the transmission plate 14, due to its moderate rigidity, will disperse the single-point thrust (such as the thrust of a certain group of pushers) into a uniform force along the length of the plate (such as the thrust spreading from the point of force to both sides, causing the transmission plate 14 to bend as a whole). When the transmission plate 14 deforms, the connection point on its outer side drives the flexible guide rail to bend synchronously (such as when the transmission plate 14 bulges upward, the flexible guide rail bends synchronously with the bulging trajectory). Due to the homogenizing effect of the transmission plate 14, the deformation of the flexible guide rail becomes smooth, without local wrinkles or excessive stretching. After the flexible guide rail deforms, the massage core 201 on its surface moves synchronously with the trajectory of the flexible guide rail, realizing a massage that conforms to the curve of the human body.

[0031] As one possible implementation method, such as Figures 1 to 4 As shown, there are two flexible guide rails, which are symmetrically arranged on the left and right sides of the chair frame 11. The orthographic projection of the two flexible guide rails on the transmission plate 14 falls on the plate surface of the transmission plate 14.

[0032] It should be noted that there are two flexible guide rails, which are symmetrically arranged on the left and right sides of the chair frame 11. For example, the first flexible guide rail 12 is located on the left side of the chair frame 11, and the second flexible guide rail 13 is located on the right side of the chair frame 11. The orthographic projection of the two flexible guide rails on the transmission plate 14 falls on the surface of the transmission plate 14. That is to say, when viewed from a direction perpendicular to the transmission plate 14 (such as a frontal view), the overall outline of the two flexible guide rails (including the connection point with the transmission plate 14 and the stress area) is projected within the plate body of the transmission plate 14. This ensures that when the transmission plate 14 deforms, its force can be transmitted to both flexible guide rails simultaneously, and the force on both flexible guide rails is uniform. This avoids "insufficient force on one side" caused by the projection of the flexible guide rails exceeding the transmission plate 14 (such as a part of the flexible guide rail on one side not being supported by the transmission plate 14, and the deformation amplitude being smaller than that on the other side).

[0033] As one possible implementation method, such as Figure 1 and Figure 4 As shown, the massage chair 1 also includes two crossbeams 27, which are arranged parallel to each other on the upper and lower sides of the chair frame 11. The two ends of each crossbeam 27 are respectively connected to the ends of the two flexible guide rails located on the same side of the massage mechanism 201.

[0034] It should be noted that the massage chair 1 also includes two crossbeams 27. The crossbeams 27 are made of high-strength rigid materials (such as aluminum alloy profiles or high-strength plastics), and their length is adapted to the spacing of the two flexible guide rails. The two crossbeams 27 are arranged parallel to each other along the vertical direction of the chair frame 11. For example, the upper crossbeam connects to the top of the flexible guide rail (such as the shoulder and neck end of the back guide rail), and the lower crossbeam connects to the bottom of the flexible guide rail (such as the waist end of the back guide rail). This connection makes the two flexible guide rails and the upper and lower crossbeams 27 together form a closed "rectangular frame" (or "parallelogram frame"). The four corners of the frame are rigid connection points, the two sides are deformable flexible guide rails, and the upper and lower sides are rigid crossbeams 27 to form a longitudinal constraint on the flexible guide rails.

[0035] As one possible implementation method, such as Figure 1 and Figure 4 As shown, the massage chair 1 also includes two limit switches, which are respectively set on the two crossbeams 27 to limit the movement of the massage mechanism 201 along the extension direction of the flexible guide rail.

[0036] It should be noted that the massage chair 1 also includes two limit switches. The limit switches adopt non-contact (such as infrared photoelectric switches, Hall switches) or contact (such as mechanical micro switches) structures, and have high sensitivity and fatigue resistance (adapting to the high-frequency start and stop of the massage mechanism 201). The two limit switches are set on the two crossbeams 27 in a one-to-one correspondence. For example, the first limit switch 101 is set on the lower crossbeam and the second limit switch 103 is set on the upper crossbeam. The sensing end of the limit switch faces the extension direction of the flexible guide rail (such as aligning with the movement path of the massage mechanism 201 along the length of the guide rail), ensuring that the mechanism can be accurately triggered when it moves to the boundary.

[0037] When the massage mechanism 201 moves up and down along the flexible guide rail (e.g., from the waist to the shoulders and neck), the preset sensors on the massage mechanism 201 (such as metal baffles or magnets) move synchronously with the massage mechanism 201, always remaining within the sensing range of the limit switches. When the massage mechanism 201 moves to the sensing area of ​​the first limit switch 101 on the lower crossbeam, the first limit switch 101 is triggered, sending a "lower stroke complete" signal to the electronic control system 102. Similarly, when the massage mechanism 201 moves to the second limit switch on the upper crossbeam... At time 103, the second limit switch 103 is triggered, sending a "upper travel complete" signal to the electronic control system 102. After receiving the limit switch signal, the electronic control system 102 immediately cuts off the power supply to the drive motor of the corresponding massage mechanism 201 (or controls the drive motor to rotate in the opposite direction), forcing the massage mechanism 201 to stop moving in the overtravel direction, and only allowing it to move in the opposite direction (such as from the shoulder and neck to the waist). If the travel needs to be readjusted, the limit state needs to be released through user operation (such as button reset) or the electronic control system 102 program.

[0038] As one possible implementation method, such as Figure 4 As shown, the massage mechanism 201 includes a drive unit 28, a gear transmission assembly connected to the drive unit 28, and a massage head 21 fixed on the rotating shaft of the gear transmission assembly. A flexible guide rail is provided with a flexible rack, and the end of the gear transmission assembly away from the drive unit 28 meshes with the flexible rack. As one possible implementation, such as... Figure 4 As shown, the gear transmission assembly includes multiple gears that mesh in sequence, and the massage head 21 is fixedly mounted on the shaft of one of the gears.

[0039] It should be noted that the massage mechanism 201 includes a drive unit 28, a gear transmission assembly, and a massage head 21. The drive unit 28 serves as a power source and can be a DC geared motor or a servo motor, possessing adjustable speed and torque characteristics (e.g., speed can be controlled via PWM signals to adjust the speed of the massage head 21). Its output shaft is rigidly connected to the input end of the gear transmission assembly (e.g., via a key connection or coupling), providing power to the entire massage mechanism 201. The gear transmission assembly can consist of 2 to 5 meshing gears (e.g., cylindrical gears or bevel gears), serving to reduce speed, increase torque, and change direction. For example, the high-speed, low-torque input of the drive unit 28 can be converted into the low-speed, high-torque output required by the massage head 21 (e.g., the drive unit 28 rotates at 3000 rpm, and after reduction by the gear transmission assembly, the massage head 21 rotates at 30 to 60 rpm). Alternatively, through a bevel gear combination, the horizontal rotational power of the drive unit 28 can be converted into the vertical oscillating or rotating motion of the massage head 21.

[0040] A "drive gear" extends from the end of the gear transmission assembly furthest from the drive member 28 (i.e., the shaft of the last stage gear). This drive gear meshes with a "flexible rack" pre-set on the side of the flexible guide rail. When the drive gear rotates, it generates a thrust along the length of the flexible guide rail through meshing with the flexible rack, causing the massage mechanism 201 to move along the flexible guide rail as a whole (e.g., moving upwards or downwards), thus adjusting the massage position. Simultaneously, because the flexible rack deforms synchronously with the flexible guide rail (e.g., when the flexible guide rail bends, the flexible rack bends synchronously), the drive gear and the flexible rack always remain meshed (i.e., there is no disengagement between the teeth), ensuring that the massage mechanism 201 can move stably on any trajectory. For example, the gear transmission assembly of this application includes a first gear 22, a second gear 23, a third gear 24, a fourth gear 25, and a fifth gear 26 meshing sequentially. The fifth gear 26 is the aforementioned drive gear, used to mesh with the flexible guide rail.

[0041] The massage head 21 (such as a silicone roller or airbag massage block) is fixed to the intermediate shaft of the gear transmission group (i.e., the shaft excluding the first and last gears) via an eccentric shaft or linkage mechanism. When the gear transmission group is running, it drives the massage head 21 to perform various basic movements: if fixed by an eccentric wheel structure, the massage head 21 oscillates in a circular motion, simulating kneading; if fixed by a bidirectional rotating gear, the massage head 21 rotates alternately in both directions, simulating massage; if fixed with a cam structure, it can reciprocate and extend, simulating tapping. These movements, combined with the movement of the massage mechanism 201 along the flexible guide rail, form a composite massage effect of "movement + kneading / massage / tapping" (such as kneading while moving along the shoulder and neck curve).

[0042] As one possible implementation method, such as Figure 4 As shown, the drive unit 28 is a drive motor with a double-headed worm gear. There are two gear transmission groups and two massage heads 21. The two gear transmission groups are respectively connected to the double-headed worm gear of the drive motor, and the two massage heads 21 are respectively set on the rotating shafts of the two gear transmission groups.

[0043] It should be noted that the drive unit 28 adopts a DC geared motor with an integrated double-headed worm gear. Worms with opposite rotation directions extend from both ends of its output shaft (e.g., the left worm rotates clockwise, and the right worm rotates counterclockwise), forming a "one-shaft, dual-drive" structure. The two gear transmission groups are symmetrically distributed (based on the central axis of the drive motor). Each gear transmission group consists of an "input gear + intermediate reduction gear set + output gear + drive gear." The input gear (i.e., the gear meshing with the worm) meshes with the corresponding worm of the drive motor (e.g., the left gear transmission group matches the left worm, and the right gear transmission group matches the right worm), converting the worm's horizontal rotational motion into the gear's vertical rotational motion. The intermediate reduction gear set can achieve speed reduction and torque increase through the meshing of 2-3 gears, ensuring sufficient pressing pressure for the massage head 21. The output gear's shaft can extend into an eccentric shaft or crank to connect to the massage head 21, converting the rotational motion into the oscillating or retracting motion of the massage head 21. The structural parameters of the two transmission groups are completely identical (such as the same gear module and reduction ratio), ensuring the basic synchronization of the massage heads 21 on both sides (such as the speed difference ≤ 2 rpm).

[0044] As one possible implementation method, such as Figure 2 and Figure 3 As shown, the number of pushers is at least one. When the number of pushers is multiple, the multiple pushers are distributed at intervals along the extension direction of the flexible guide rail (or along the length direction of the fixed plate 15). For example, the first pusher 16 is located in the waist area and the second pusher 17 is located in the shoulder area, so that the electronic control system 102 can control the pusher action in different areas accordingly.

[0045] As one possible implementation method, such as Figure 2 and Figure 3 As shown, the actuating component can be an airbag, a thrust motor, or a linkage structure. Those skilled in the art should be able to make reasonable selections and designs based on actual conditions; no specific limitations are imposed here.

[0046] This application also provides a car that includes the massage chair 1 described above. Since the structure and beneficial effects of the massage chair 1 have been described in detail in the foregoing embodiments, they will not be repeated here.

[0047] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0048] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
