Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a massage mechanism component. Background Technology

[0002] With the fast pace of modern life, people spend long hours working at desks and frequently use electronic devices, leading to physical fatigue and mental stress, making neck, shoulder, and back pain commonplace. Traditional massagers only offer a single massage angle, which cannot be adjusted for different users. This makes it difficult for traditional massagers to meet diverse individual needs in actual use, thus reducing the user experience and massage effect. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a massage mechanism component and a massager to solve the technical problems of traditional massagers having a single angle and poor user experience due to the fixed angle.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A massage mechanism assembly includes an upper base and a lower base rotatably connected at one end. The upper base has a massage mechanism body located away from the rotatable connection point. The lower base has a drive device and a sloping protrusion on the side near the upper base. The drive device has a fixed end and an output end. The fixed end is rotatably connected to the lower base, and the output end faces the sloping surface and the rotatable connection point. The output end is connected to a roller via a roller shaft, which is slidably connected to the upper base. When the drive device drives the roller to move along the sloping surface, the roller shaft drives the upper base to move, thereby adjusting the tilt angle of the upper base relative to the lower base.

[0006] Furthermore, the roller passes through the center of the roller, and the upper base extends vertically to the side near the lower base with a connecting ear plate, the connecting ear plate having a sliding groove adapted to slide with the roller.

[0007] Furthermore, there are two connecting lugs, and the protrusion is located between the two connecting lugs.

[0008] Furthermore, the length of the roller is greater than the distance between the two connecting lugs.

[0009] Furthermore, the upper base is rotatably connected to the highest point of the slope.

[0010] Furthermore, the upper base is provided with a coaxial connecting hole at one end and the highest point of the slope, and a first pin passes through the connecting hole.

[0011] Furthermore, the fixed end is rotatably connected to the lower base via a second pin.

[0012] Furthermore, the lower base has at least one positioning post on the side near the upper base. When the upper base and the lower base are parallel to each other, the positioning post abuts against the side of the upper base near the lower base.

[0013] Furthermore, the lower base has a plurality of spaced positioning posts on one side near the upper base.

[0014] A massager includes the massage mechanism assembly as described above.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model proposes a massage mechanism assembly that, through a rotating connection structure between upper and lower bases, utilizes a drive device to move rollers along the slope of the lower base, thereby driving the roller shaft to apply a lifting force to the upper base. This causes the upper base to rotate around the rotating connection point, thus achieving adjustment of the massage angle. This structure avoids the problems of limited angle and poor user experience associated with traditional fixed angles, better meeting diverse individual needs. Simultaneously, the transmission path is simple and reliable, and the adjustment process is smooth and shock-free, significantly enhancing user comfort and safety.

[0017] 2. The massage mechanism component proposed in this utility model has a protrusion located between two connecting ear plates. This arrangement not only ensures the centering of the path when the roller moves along the slope, but also makes the entire angle adjustment mechanism more compact and reasonable in spatial distribution, thereby improving the stability and smooth operation of the overall structure.

[0018] 3. The massage mechanism component proposed in this utility model has an upper base rotatably connected to the highest point of the slope. By setting the rotatable connection between the upper base and the lower base at the highest point of the slope, when the drive device pushes the roller to move along the slope, the high point can be used as a fixed rotation center to form a stable lever-type lifting mechanism, thereby realizing smooth and controllable angle adjustment of the upper base.

Detailed Implementation

[0026] The following is combined with Figures 1-5 This utility model will be described in detail.

[0027] A massage mechanism assembly includes an upper base 10 and a lower base 30 rotatably connected at one end. The upper base 10 has a massage mechanism body 20 located away from the rotatable connection point. The lower base 30 has a drive device 40 and a protrusion 50 with a slope 501 on the side near the upper base 10. The drive device 40 has a fixed end and an output end. The fixed end is rotatably connected to the lower base 30, and the output end faces the slope 501 and the rotatable connection point. The output end is connected to a roller 602 via a roller 601. The roller 601 is slidably connected to the upper base 10. When the drive device 40 drives the roller 602 to move along the slope 501, the roller 601 drives the upper base 10 to move, thereby adjusting the tilt angle of the upper base 10 relative to the lower base 30.

[0028] Specifically, the upper base 10 serves as the basic platform for supporting the massage function module. The massage mechanism body 20 is mounted on its top, capable of performing various massage actions. The upper base 10 has a plate-like structure, facilitating integration and assembly with other components. The lower base 30 is the supporting base for the entire assembly. Its first end is hinged to the corresponding end of the upper base 10, forming a rotation fulcrum. The drive device 40 can be an actuator capable of outputting linear or rotary motion, such as a lead screw mechanism, electric push rod, pneumatic cylinder, hydraulic cylinder, stepper motor with linkage mechanism, worm gear mechanism, or rack and pinion mechanism. For example, in this embodiment, when a lead screw mechanism is used, the motor drives the lead screw to rotate, causing the nut to move axially, thereby pushing the connected output rod forward or backward. These different types of drive devices 40 can be selected and replaced according to the actual spatial layout and power requirements, as long as the output end has controllable linear displacement capability. The roller 602, as a moving element in direct contact with the slope 501, is positioned on the slope 501 of the protrusion 50 and can move up or down along the slope 501 under driving action. The roller 602 is typically made of high-hardness rubber, polyurethane, or metal-coated material to ensure sufficient wear resistance and maintain good friction performance on the slope 501, preventing slippage. The output end is connected to a roller 601, which is generally a cylindrical metal rod with a ground surface to improve smoothness and reduce sliding friction. The roller 601 and... The sliding connection of the upper base 10 can be achieved by setting a sliding groove 1011, a guide rail or a linear bearing at the bottom of the upper base 10 to ensure that the roller 601 does not jam or deviate during the movement; the angle of the slope 501 can be designed to be any value between 15° and 60° according to the required adjustment range, and the slope in this embodiment is 21°; there are two rollers 602, which are coaxially arranged on the roller 601 and located on both sides of the output end of the drive device 40, so as to improve the stability of the movement along the slope 501 and distribute the load.

[0029] In this embodiment, the roller 601 passes through the center of the roller 602. The upper base 10 has a connecting ear plate 101 extending vertically on the side near the lower base 30. The connecting ear plate 101 has a sliding groove 1011 that is slidably adapted to the roller 601. Specifically, the roller 601 has a limiting groove adapted to the roller 602 or limiting protrusions located at both ends of the roller 602, which are used to limit the change of position of the roller 602 relative to the roller 601 and prevent the roller 602 from rolling off-center when rolling on the slope 501. The length direction of the sliding groove 1011 is parallel to the upper base 10.

[0030] In this embodiment, there are two connecting ear plates 101, and the protrusion 50 is located between the two connecting ear plates 101. Specifically, this arrangement ensures that the roller 602 moves along the slope 501 with a centered path, making the force center line of the roller 602 coincide with the symmetry plane of the two connecting ear plates 101. This effectively avoids the torsional load caused by eccentric load being transmitted to the roller 601 and the slide groove 1011 structure, reducing wear and vibration, and improving smooth operation. It also makes the entire angle adjustment mechanism more compact and reasonable in spatial distribution, making full use of the idle space inside the connecting ear plates 101. When the upper base 10 is lowered to its lowest position, the connecting ear plates 101 and the protrusion 50 are staggered, so that the upper base 10 is as close as possible to the lower base 30, which is conducive to the overall thinness and lightweight design. Since the protrusion 50 is located in a protected internal area, it is not easily affected by external collisions or foreign object intrusion, which improves the reliability and service life of the mechanism. This structure facilitates positioning and alignment operations during assembly, which is conducive to realizing automated production and modular assembly. Overall, it has improved the stability of the overall structure and the smoothness of operation.

[0031] In this embodiment, the length of the roller 601 is greater than the distance between the two connecting lugs 101. When the length of the roller 601 is greater than the distance between the two connecting lugs 101, even when the upper base 10 is tilted at its maximum angle relative to the lower base 30, both ends of the roller 601 can still reliably remain inside their respective sliding grooves 1011, preventing the ends from coming out of the sliding grooves 1011 due to deflection. The length of the roller 601 can be set to be 5mm to 20mm greater than the net distance between the inner edges of the two connecting lugs 101 to allow for sufficient safety margin.

[0032] In this embodiment, the upper base 10 is rotatably connected to the highest point of the slope 501. Specifically, by setting the rotatable connection between the upper base 10 and the lower base 30 at the highest point of the slope 501, when the drive device 40 pushes the roller 602 to move along the slope 501, this high point can be used as a fixed rotation center to form a stable lever-type lifting mechanism, thereby achieving smooth and controllable angle adjustment of the upper base 10. This rotatable connection can be achieved through a pin, shaft, bearing, or pivot structure.

[0033] In this embodiment, the upper base 10 has a coaxial connecting hole 701 at one end and the highest point of the slope 501, through which a first pin 702 passes. After the first pin 702 is inserted into the connecting hole 701, a coaxial hinge is formed, creating a stable pivot point. This allows the upper base 10 to rotate smoothly around the axis relative to the lower base 30, ensuring stability and low friction during rotation, thereby reliably achieving the overall angle adjustment function of the massage mechanism assembly. This connection method is simple in structure and easy to assemble, while possessing sufficient mechanical strength to withstand the shear force and bending moment generated during repeated adjustments, making it suitable for high-frequency use scenarios. Both ends of the first pin 702 can protrude a certain amount outside the connecting hole 701 and are equipped with anti-detachment components, such as cotter pins, elastic retaining rings, and nylon anti-reverse locking buckles.

[0034] In this embodiment, the fixed end of the drive device 40 is rotatably connected to the lower base 30 via the second pin 703. Both ends of the second pin 703 are also axially limited by anti-disengagement elements such as cotter pins and elastic retaining rings to prevent it from accidentally disengaging during operation.

[0035] In this embodiment, the lower base 30 is provided with at least one positioning post 80 on the side near the upper base 10. When the upper base 10 and the lower base 30 are parallel to each other, the positioning post 80 abuts against the side of the upper base 10 near the lower base 30, that is, against the bottom of the upper base 10. Furthermore, the lower base 30 is provided with a plurality of spaced positioning posts 80 on the side near the upper base 10, that is, on the top of the lower base 30, specifically three. The top of each positioning post 80 may be fitted with a rubber buffer pad, or the positioning post 80 may be made of an elastic material to absorb the impact when the upper base 10 falls back, reduce noise and extend service life.

[0036] This embodiment also proposes a massager, including the massage mechanism assembly as described above.

[0037] The working principle of the massage mechanism component proposed in this utility model is as follows:

[0038] Before the drive unit 40 is started, such as Figure 1 As shown, in its natural state, the upper base 10 and the lower base 30 are parallel to each other. After the drive device 40 is started, its output end pushes the roller 602 to climb up the slope 501 of the protrusion 50. The roller 602 transmits the vertical lifting force to the bottom of the upper base 10 through the roller 601. Since one end of the upper base 10 is hinged to the lower base 30, it rotates around the hinge point, i.e., the rotation connection point, under the action of this lifting force, thus forming an inclination angle, such as... Figure 2 As shown; conversely, when the roller 602 slides down the slope 501, the upper base 10 falls back to the initial horizontal state, and the upper base 10 and the lower base 30 are parallel to each other.

[0039] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
