Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and more specifically to a massage mechanism angle adjustment device and an adjustable-angle shoulder and neck massage mechanism. Background Technology

[0002] Massage mechanisms can typically be assembled independently as a dedicated massage device for a specific body part, or integrated into massage chairs, massage beds, or other massage equipment as part of a comprehensive massage system. Whether used alone or within a massage chair or bed, the mechanism is first fixed in place, and the user then places the area to be massaged against the corresponding area on the massage device where the massage mechanism is positioned before activating the massage. However, due to individual differences in body shape (height, weight, etc.), the areas requiring massage may differ relative to the positioning of the massage mechanism within the same fixed massage device. When massaging individuals of different body types, this can lead to misalignment of the massage area, resulting in reduced user comfort.

[0003] Taking a neck and shoulder massage mechanism fixedly mounted on a massage chair as an example, the position of the massage mechanism on the body varies depending on the user's height and build. For a taller user, the massage mechanism might be positioned on their back; for a shorter user, it might be positioned above the neck or at the back of the head. Therefore, this type of massage chair cannot adapt to different user body shapes, and the angle of the massage mechanism cannot be adjusted, resulting in inadequate or uncomfortable massage. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable massage mechanism angle adjustment device.

[0005] To achieve the above objectives, this utility model provides a massage mechanism angle adjustment device, located below the massage mechanism, including an angle adjustment mechanism. The angle adjustment mechanism includes a support arm, a first motor, a first transmission component, and a rotating shaft. The first motor and the rotating shaft are connected by the first transmission component. One end of the support arm is supported at one end of the bottom of the massage mechanism, and the other end of the support arm is fixed to the rotating shaft and rotates with the transmission shaft. The rotating support arm drives the massage mechanism to rotate at a certain angle.

[0006] Furthermore, the first transmission assembly includes a first transmission gear, a second worm, and an angle adjustment gear. The first transmission gear is fixedly mounted on the second worm and is connected to the first motor for transmission. The angle adjustment gear is fixedly mounted on the rotating shaft and meshes with the helical teeth on the second worm, thereby being connected to the second worm for transmission.

[0007] Furthermore, it also includes a mounting housing, and the massage mechanism has a lower housing. The angle adjustment mechanism is located inside the mounting housing. The upper end of the lifting arm extends through the upper surface of the mounting housing and is supported at the rear end of the lower housing of the massage mechanism. The front end of the lower housing of the massage mechanism is pivotally connected to the upper surface of the mounting housing.

[0008] Furthermore, the angle adjustment gear is a sector gear.

[0009] Furthermore, the rear end of the lower housing is provided with a lifting groove for the lifting arm to be inserted and limited therein, and the lifting arm bends upward and extends forward into the lifting groove.

[0010] Furthermore, the upper surface of the mounting housing is provided with complementary arc-shaped guide grooves corresponding to the lower housing of the massage mechanism. The arc-shaped guide grooves are located between the supported part at the rear end of the lower housing of the massage mechanism and the pivot point at the front end.

[0011] Furthermore, an angle sensor is provided at one end of the rotating shaft to detect the rotation angle of the rotating shaft.

[0012] Furthermore, it also includes a traveling mechanism, which is disposed within the mounting housing and is used to drive the mounting housing together with the angle adjustment mechanism to slide on a base.

[0013] Furthermore, the walking mechanism includes a second motor and a second transmission component that is connected to the second motor. The second transmission component includes a first worm gear, a second transmission gear, a third transmission gear, and a walking gear that mesh in sequence. A rack that meshes with the walking gear is provided on the base.

[0014] This utility model also provides an adjustable angle neck and shoulder massage mechanism, including the above-mentioned massage mechanism angle adjustment device. The bottom of the massage mechanism is a lower shell. The massage mechanism includes a neck massage component, a shoulder massage component, an eccentric component, a third motor, and a massage shaft driven by the third motor to rotate. The eccentric component is located at both ends of the massage shaft. The neck massage component and the shoulder massage component are sleeved on the eccentric component. The eccentric component drives the neck massage component and the shoulder massage component to swing.

[0015] After adopting the above solution, the present invention has at least the following technical effects: by setting the lifting arm on the rotating shaft and rotating it through the first transmission component driven by the first motor, the tilt angle of the massage core lifted on the lifting arm is changed, thereby changing the massage angle of the massage core relative to the human body, so that the massage core can be flexibly adapted to individuals of different body types and improve comfort.

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] See Figures 1-5This utility model discloses a massage mechanism angle adjustment device, which is located below the massage mechanism 3. The angle adjustment device includes an angle adjustment mechanism 1, which includes a support arm 2, a first motor 11, a first transmission component 12, and a rotating shaft 13. The first motor 11 and the rotating shaft 13 are connected by the first transmission component 12. One end of the support arm 2 is supported at one end of the bottom of the massage mechanism 3, and the other end of the support arm 2 is fixed to the rotating shaft 13 and rotates with the rotation of the transmission shaft 13. After rotation, the support arm 2 can change the support height and support angle, thereby driving the massage mechanism 3 to rotate by a certain angle and adjusting the massage angle.

[0030] See Figure 4 , Figure 5 The first transmission assembly 12 includes a first transmission gear 121, a second worm gear 122, and an angle adjustment gear 123. The first transmission gear 121 is fixedly mounted on the second worm gear 122 and is connected to the first motor 11 for transmission. The angle adjustment gear 123 is fixedly mounted on the rotating shaft 13 and meshes with the helical teeth on the second worm gear 122, thereby being connected to the second worm gear 122 for transmission.

[0031] In this embodiment, the output shaft of the first motor 11 is a first worm gear 111 (or the first worm gear 111 can be provided on the output shaft of the first motor 11). The first worm gear 111 meshes with the first gear so that the first gear is connected to the first motor 11 for transmission.

[0032] See Figure 3The angle adjustment device also includes a mounting housing 14, and the massage mechanism 3 has a lower housing 31. The angle adjustment mechanism 1 is disposed within the mounting housing 14. In this embodiment, the mounting housing 14 has an upper cover 141 and a lower cover 142. The angle adjustment mechanism 1 is disposed between the upper cover 141 and the lower cover 142. The upper end of the lifting arm 2 extends through the upper cover 141 and is supported at the rear end of the lower housing 31 of the massage mechanism 3. In this embodiment, a lifting groove 313 (not specifically shown in the figure) is also provided at the rear end of the lower housing 31 for the lifting arm 2 to be inserted and limited therein. The rotating lifting arm 2 drives the massage mechanism 3 to be lifted to achieve an angle change. In this embodiment, the lifting arm 2 bends upward and extends forward into the lifting groove 313, and a stop section 21 is formed at the free end of the lifting arm 2. The lifting groove 313 corresponds to the shape of the lifting arm 2. The lower housing 31 of the massage mechanism 3 has at least one pivot groove 311 at its front end. In this example, there are two pivot grooves 311. The upper surface of the upper cover 141 of the mounting housing 14 has a corresponding pivot lug 1411. The pivot lug 1411 passes through the pivot groove 311 to achieve hinge connection. The front end of the lower housing 31 of the massage mechanism 3 is pivotally connected to the upper cover 141 of the mounting housing 14 through the pivot groove 311 and the pivot lug 1411. The front end of the lower housing 31 of the massage mechanism 3 is pivotally connected, and the rear end of the lower housing 31 of the massage mechanism 3 is supported by the lifting arm 2. When the rotating shaft 13 drives the support angle of the lifting arm 2 to change, it drives the lower housing 31 to rotate around the pivot point at the front end of the lower housing 31, thereby realizing the angle change of the massage mechanism 3.

[0033] The angle adjustment gear 123 can be a sector gear. In this embodiment, the angle adjustment gear 123 is formed as a sector gear with a central angle of 45°. This limits the rotation angle of the rotating shaft 13 to 45°. Of course, the angle adjustment gear can also be formed as a sector gear with a larger arc or directly as a circular gear. Furthermore, an angle sensor 131 for detecting the rotation angle of the rotating shaft 13 can be provided at one end of the rotating shaft 13. By detecting the rotation angle of the rotating shaft 13, the tilt angle of the massage mechanism 3 can be obtained.

[0034] To ensure a smooth and non-displacement-free angle adjustment process for the massage mechanism 3, the upper surface of the mounting housing 14 of the angle adjustment device is provided with a complementary arc-shaped guide groove 312 corresponding to the lower housing 31 of the massage mechanism 3. The arc-shaped guide groove 312 is located between the supported portion at the rear end and the pivot portion at the front end of the lower housing 31 of the massage mechanism 3. In this embodiment, an arc-shaped groove is recessed upward in the middle of the lower housing 31, and an arc-shaped protrusion is protruded upward on the upper cover 141, which can be precisely inserted into the arc-shaped groove. The arc-shaped groove and the arc-shaped protrusion fit together to form the arc-shaped guide groove 312.

[0035] The angle adjustment mechanism 1 in the angle adjustment device can be controlled by a separate circuit, which is electrically connected to the control circuit and switch via a separate wire 5, without needing to be started together with the massage mechanism 3. When the massage mechanism 3 with this angle adjustment device needs to be activated, the user can control the circuit of the angle adjustment mechanism 1 separately before starting the massage to adjust the angle of the massage mechanism 3. After adjusting to a suitable angle, the massage mechanism 3 can then be started for massage.

[0036] The angle adjustment device in this embodiment also includes a walking mechanism 4, which is disposed inside the mounting housing 14. The walking mechanism 4 is used to drive the mounting housing 14 together with the angle adjustment mechanism 1 to slide on a base, so that the angle adjustment device can be slidably disposed on a base (not shown), thereby allowing the massage core 3 to be slidably disposed on the base. The base can be the back shell of a massage chair or a massage bed.

[0037] See Figure 5 The walking mechanism 4 includes a second motor 41 and a second transmission assembly 42 that is driven by the second motor 41. The second transmission assembly 42 includes a first worm gear 421, a second transmission gear 422, a third transmission gear 423, and a walking gear 424 that mesh in sequence. A rack (not shown) that meshes with the walking gear 424 is provided on the base. In this embodiment, the output shaft of the second motor 41 is a third worm 411 (or the output shaft of the second motor 41 may be provided with a third worm 411). The third worm 411 meshes with the first worm gear 421, thereby driving the second transmission assembly 42 and the second motor 41.

[0038] Preferably, a travel guide groove 43 is provided at the bottom of the lower cover 142 of the housing 14, and a corresponding travel guide rail (not shown) is provided on the base, so that the entire angle adjustment device and the massage mechanism 3 can slide along a preset route.

[0039] By setting an angle adjustment mechanism 1 in the angle adjustment device, the lifting arm 2 is set on the rotating shaft 13 and driven to rotate by the first motor 11 through the first transmission component 12, thereby changing the tilt angle of the massage core 3 that is supported and pivoted on the lifting arm 2. This allows the massage angle of the massage core 3 relative to the human body to be changed, making the massage core 3 flexibly applicable to individuals of different body types and improving comfort.

[0040] See Figure 6 This utility model also provides an adjustable-angle shoulder and neck massage mechanism 3, including the angle adjustment device of the massage mechanism 3 in the above embodiment. The bottom of the massage mechanism 3 is a lower shell 31, and the top of the massage mechanism 3 is also provided with an upper shell 38. Figure 6 (Hidden upper shell 38).

[0041] The massage mechanism 3 (inside the lower housing 31) includes a neck massage component 32, a shoulder massage component 33, an eccentric component 34, a third motor 35, and a massage shaft 36 driven by the third motor 35 to rotate. The eccentric component 34 is located at both ends of the massage shaft 36. The neck massage component 32 and the shoulder massage component 33 are sleeved on the eccentric component 34. The eccentric component 34 drives the neck massage component 32 and the shoulder massage component 33 to swing.

[0042] In this embodiment, the third motor 35 and the massage shaft 36 are connected by a third transmission component 37. The third transmission component 37 includes a second worm gear 371 and a massage transmission gear 372. The output shaft of the third motor 35 is a worm (not shown). The second worm gear 371 meshes with the worm of the third motor 35. The massage transmission gear 372 is fixedly mounted on the massage shaft 36 and meshes with the second worm gear 371, thereby driving the massage shaft 36 to rotate. When the massage shaft 36 rotates, the neck massage component 32 and the shoulder massage component 33 sway, realizing kneading and pinching actions.

[0043] The above is merely one embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
