[0002] A back massager is a device specifically designed for back massage. It is typically used to relieve back pain, promote blood circulation, and provide a comfortable massage experience. It usually uses multiple massage heads to perform multi-point massage and kneading on the back.

[0003] Most existing back massagers use multiple sets of massage heads for multi-point massage. The massage heads themselves and their internal transmission structures cannot move. The need for multiple sets of drive transmission structures increases the cost of the device and also increases the difficulty of subsequent maintenance and repair. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing back massagers use multiple sets of massage heads for multi-point massage, but the massage heads themselves and their internal transmission structures cannot move, requiring multiple sets of drive transmission structures which increases the cost of the device and makes subsequent maintenance and repair more difficult. This invention provides a flexible walking back massager.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible walking back massager, comprising: a core assembly, a flexible rack, a guide rail, a conductive PCB, and a hand control assembly, wherein the core assembly includes a rear housing, a front housing, a massage head, and an internal transmission mechanism;

[0006] The internal transmission mechanism of the mechanism includes a motor, double gears, massage gears, double bevel gears, bevel gears, straight gears, and traveling gears.

[0007] As a further embodiment of this utility model: the motor is fixed on the rear housing, the motor has a bidirectional output structure, and a screw is provided at the output end. The double gear is composed of two sets of coaxial gears of different sizes closely fitted together, wherein the larger gear meshes with the screw and the smaller gear meshes with the massage gear.

[0008] As a further embodiment of this utility model: the double bevel teeth consist of two parts, one part being straight teeth that mesh with massage teeth, and the other part being conical teeth on the side that mesh with bevel teeth. A shaft fixing component is fixedly connected inside the rear housing, and a connecting shaft passes through the shaft fixing component. The bevel teeth are fixedly sleeved on the connecting shaft, and the straight teeth are fixedly sleeved at the end of the connecting shaft. The traveling teeth consist of two sets of coaxial gears of different sizes, wherein the larger gear meshes with the straight teeth, and the smaller gear meshes with the flexible rack.

[0009] As a further embodiment of this utility model: the number of double teeth, massage teeth, double bevel teeth, bevel teeth, straight teeth, and walking teeth, as well as the connecting structure, are all provided in two sets, symmetrically arranged inside the rear housing. The number of flexible racks is provided in two sets, connected to each other by rack connecting frames. An arc-shaped guide rail is provided on the back side of the rear housing. A meshing groove is provided through the middle section of the arc-shaped guide rail at the rear housing, allowing the walking teeth and flexible racks to mesh perpendicularly to the human body. A rack limiting plate is installed at the arc-shaped guide rail on the back side of the rear housing. The flexible rack passes between the arc-shaped guide rail and the rack limiting plate. The meshing structure between the walking teeth and the flexible rack enables the entire mechanism assembly to move vertically.

[0010] As a further improvement of this utility model: both sets of massage teeth are engaged with massage heads, one end of which penetrates the front housing and is driven to rotate by the massage teeth.

[0011] As a further embodiment of this utility model: the conductive PCB is disposed on one side of the guide rail and is controlled and driven by the manual control component, and is electrically connected to the motor. The conductive circuit etched and coated on the conductive PCB powers the motor and drives it electrically. The guide rail passes through the inside of the movement assembly to assist the movement assembly in directional movement.

[0012] As a further embodiment of this utility model: the rear housing and the front housing together form the outer housing of the movement assembly, and the double teeth, massage teeth, double bevel teeth, bevel teeth, straight teeth and walking teeth are all fixed-point rotatable structures achieved by limiting posts sleeved inside the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the massage head rotates or oscillates through the gear transmission mechanism of the core assembly to achieve the kneading massage function. The massage teeth not only drive the massage head to rotate, but also drive the intermediate transmission gear of the walking teeth. The gear direction is changed through double bevel teeth and bevel teeth, allowing the walking teeth to move vertically with the flexible rack. This allows the entire core assembly to move on the flexible rack, thereby massaging different parts of the back. The flexible material of the flexible rack and the design of the meshing surface perpendicular to the human body allow the entire core assembly to make flexible curved movements. This allows the flexible rack to fit closely to different chairs and makes the massage core assembly fit the back more closely. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0026] Reference Figures 1 to 7 In this embodiment of the utility model, a flexible walking back massager includes: a core assembly 1, a flexible rack 2, a guide rail 3, a conductive PCB 4, and a hand control assembly 5. The core assembly 1 includes a rear shell 6, a front shell 7, a massage head 8, and an internal transmission mechanism.

[0027] The internal transmission mechanism of the movement assembly 1 includes a motor 100, a double gear 101, a massage gear 102, a double bevel gear 103, a bevel gear 104, a straight gear 105, and a traveling gear 106.

[0028] Reference Figure 2 and Figure 3 The motor 100 is fixed on the rear housing 6. The motor 100 has a bidirectional output structure and a screw 1001 is provided at the output end. The double gear 101 is composed of two sets of coaxial gears of different sizes that are closely fitted together. The larger gear meshes with the screw 1001, and the smaller gear meshes with the massage gear 102.

[0029] Using the above scheme: the screw 1001 symmetrically arranged at the bidirectional output end of the motor 100 meshes with the larger gear in the double gear 101. When the double gear 101 rotates, it drives the massage tooth 102 that meshes with the smaller gear to rotate. The smaller gear in the double gear 101 and the massage tooth 102 are located on the same plane.

[0030] Reference Figures 3 to 5The double bevel gear 103 consists of two parts: one part is a straight tooth that meshes with the massage tooth 102, and the other part is a tapered tooth on the side that meshes with the bevel gear 104. A shaft fixing member 1041 is fixedly connected inside the rear housing 6. A connecting shaft 1042 passes through the shaft fixing member 1041. The bevel gear 104 is fixedly sleeved on the connecting shaft 1042, and the straight tooth 105 is fixedly sleeved at the end of the connecting shaft 1042. The traveling gear 106 consists of two sets of coaxial gears of different sizes, with the larger gear meshing with the straight tooth 105 and the smaller gear meshing with the flexible rack 2.

[0031] Using the above scheme: the outer gear of the double bevel gear 103 and the massage gear 102 are located on the same plane and mesh with each other. The conical teeth on the side of the double bevel gear 103 mesh with the bevel gear 104 sleeved on the connecting shaft 1042. The rotating bevel gear 104 drives the straight gear 105, which is also sleeved on the connecting shaft 1042, to rotate synchronously. The straight gear 105 meshes with the traveling gear 106 on the same horizontal plane. When meshing and rotating, the small gear in the traveling gear 106 rotates. The small gear meshes with the flexible rack 2, thereby enabling the massage gear 102 to rotate and drive the massage head 8 to rotate and knead, while also allowing the entire core assembly 1 to move on the flexible rack 2.

[0032] Reference Figures 1 to 5 The mechanism includes two sets of double teeth 101, massage teeth 102, double bevel teeth 103, bevel teeth 104, straight teeth 105, and walking teeth 106, as well as two sets of connecting structures, all symmetrically arranged inside the rear housing 6. Two sets of flexible racks 2 are also provided, connected to each other via rack connecting brackets 201. An arc-shaped guide rail 601 is provided on the back side of the rear housing 6. A meshing groove 602 is provided through the middle section of the arc-shaped guide rail 601 at the rear housing 6, allowing the walking teeth 106 and flexible racks 2 to mesh perpendicularly to the human body. A rack limiting plate 603 is installed at the arc-shaped guide rail 601 on the back side of the rear housing 6. The flexible racks 2 pass between the arc-shaped guide rail 601 and the rack limiting plate 603, and the meshing structure between the walking teeth 106 and the flexible racks 2 enables the entire mechanism assembly 1 to move vertically.

[0033] The above scheme is adopted: the symmetrically arranged transmission structure can perform double-row moving rotation kneading operation on the back. The flexible rack 2 is limited by the rack limiting plate 603 installed on the back side of the rear shell 6 through the arc-shaped guide rail 601, which ensures the accurate guiding position of the flexible rack 2. The arc-shaped guide rail 601 also ensures the flexibility of the flexible rack 2. The flexible rack 2 is set perpendicular to the human body in the meshing groove 602 with the meshing surface of the walking tooth 106. With the help of the arc-shaped guide rail 601, the entire core assembly 1 can flexibly complete the curved movement.

[0034] Reference Figure 2Both sets of massage teeth 102 are engaged with massage heads 8, and one end of the massage head 8 passes through the front housing 7 and is driven to rotate by the massage teeth 102.

[0035] The above solution is adopted: the massage head 8 is set with a smooth convex arc surface structure to provide a comfortable touch to the user's back.

[0036] Reference Figure 1 The conductive PCB4 is located on one side of the guide rail 3 and is controlled and driven by the hand control component 5. It is also electrically connected to the motor 100. The motor 100 is electrically driven by the conductive lines etched and coated on the conductive PCB4. The guide rail 3 passes through the inside of the movement assembly 1 to assist the movement of the movement assembly 1.

[0037] The main purpose of setting the conductive PCB4 on the guide rail 3 is to achieve electrical connection and support. The conductive PCB4 can serve as the electrical connection part of the guide rail system, ensuring that current can be effectively transmitted between different components or modules. It can also provide structural support, which can help stabilize and fix other electronic components, preventing them from moving or shifting during use.

[0038] Reference Figure 1 and Figure 7 The rear housing 6 and the front housing 7 form the outer housing of the mechanism assembly 1. The double teeth 101, massage teeth 102, double bevel teeth 103, bevel teeth 104, straight teeth 105 and walking teeth 106 are all fixed-point rotatable structures achieved by being sleeved on the limiting post inside the housing.

[0039] The above scheme is adopted: both the rear housing 6 and the front housing 7 are provided with support structures for limiting and fixing the position of each gear structure, so as to ensure that the position of each gear group relative to the core assembly 1 is fixed and to provide a support center point.

[0040] The working principle of this utility model is as follows: The main purpose of setting the conductive PCB4 on the guide rail 3 is to achieve electrical connection and support. The conductive PCB4 can serve as the electrical connection part of the guide rail system, ensuring that current can be effectively transmitted between different components or modules. It can also provide structural support, helping to stabilize and fix other electronic components, preventing them from moving or shifting during use. Both the rear housing 6 and the front housing 7 are provided with support pillar structures for limiting and fixing the positioning points of each gear structure, ensuring that the position of each set of gears relative to the core assembly 1 is fixed, and providing support center points. The screws 1001 symmetrically arranged at the bidirectional output end of the motor 100 mesh with the larger gear in the double gear 101. When the double gear 101 rotates, it drives the massage teeth 102 that mesh with the smaller gear to rotate. The smaller gear in the double gear 101 and the massage teeth 102 are located on the same plane. The outer gear of the double bevel gear 103 and the massage teeth 102 are located on the same plane and mesh with each other. The conical teeth on the side of the double bevel gear 103 mesh with the bevel teeth 104 sleeved on the connecting shaft 1042. The rotating bevel teeth 104 drive the straight teeth 105, which are also sleeved on the connecting shaft 1042, to rotate synchronously. When the spur gear 105 rotates, it meshes with the traveling gear 106 on the same horizontal plane. During this meshing rotation, the small gear in the traveling gear 106 rotates, and the small gear meshes with the flexible rack 2. This allows the massage teeth 102 to rotate, driving the massage head 8 to rotate and knead. Simultaneously, the entire mechanism assembly 1 moves on the flexible rack 2. The flexible rack 2 is limited by a rack limiting plate 603 installed on the back side of the rear housing 6, passing through an arc-shaped guide rail 601. This ensures the accurate guiding position of the flexible rack 2, and the arc-shaped guide rail 601 also ensures the flexibility of the flexible rack 2. 2. The meshing surface of the walking teeth 106 in the meshing groove 602 is set perpendicular to the human body. With the help of the arc guide rail 601, the entire core assembly 1 can flexibly complete the curved movement. The symmetrically arranged transmission structure can perform double-row moving rotation kneading operation on the back. The flexible material of the flexible toothed bar 2 and the design of the meshing surface perpendicular to the human body can make the entire core assembly 1 flexibly perform curved movement. The flexible toothed bar 2 can fit closely to the chair and be used with different seats. It also makes the massage core assembly 1 fit the back better. The massage head 8 is set with a smooth convex arc surface structure to provide a comfortable touch to the user's back.

[0041] The massage head 8 is rotated or oscillated by the gear transmission mechanism of the core assembly 1 to achieve the kneading massage function. The massage teeth 102 not only drive the massage head 8 to rotate, but also drive the intermediate transmission gear of the walking teeth 106. The gear direction is changed by the double bevel teeth 103 and bevel teeth 104, so that the walking teeth 106 and the flexible rack 2 can move vertically, so that the entire core assembly 1 can move on the flexible rack 2, thereby massaging different parts of the back. The flexible material of the flexible rack 2 and the design of the meshing surface perpendicular to the human body can make the entire core assembly 1 move flexibly in curves, so that the flexible rack 2 can fit closely to the chair and be used with different seats, and also make the massage core assembly 1 fit the back better.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
