[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] The following is a reference appendix. Figure 1-6 Description of a massage head assembly 100 according to an embodiment of the present invention.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 According to a first aspect of the present invention, a massage head assembly 100 includes a massage head 10, a drive shaft 20, and a connector 30.

[0038] Specifically, the drive shaft 20 is along the first direction (e.g., Figure 3 The shaft extends in the front-back direction and is connected to the massage head 10 to drive the massage head 10 to rotate around the axis of the drive shaft 20; the connector 30 is located between the drive shaft 20 and the massage head 10, and the connector 30 is rotatably connected to the drive shaft 20 around the first sphere center, and the massage head 10 is located on the connector 30.

[0039] For example, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the massage head 10 has multiple spaced protrusions for massaging the user's waist. The drive shaft 20 extends in the front-to-back direction, and the rear end of the massage head 10 is connected to the front end of the drive shaft 20 via a connector 30. It should be explained that the connector 30 is rotatably connected to the drive shaft 20 around a first sphere center, which is the instantaneous rotation center of the massage head 10 at a certain moment. That is, at that instant, the movement trajectory of the massage head 10 can be considered as rotation around this point, thus allowing the massage head 10 to rotate to any position to meet the user's needs.

[0040] When using the massage head assembly 100 for massage, the drive shaft 20 drives the connector 30 to rotate, and the connector 30 drives the massage head 10 to rotate around the axis of the drive shaft 20. When the position of the massage head 10 is not suitable, the user applies a force to the massage head 10, and the force causes the massage head 10 to rotate relative to the drive shaft 20 through the connector 30, thereby achieving the adjustment of the position of the massage head 10.

[0041] The massage head assembly 100 of this utility model is equipped with a connector 30, which allows the position of the massage head 10 to be adjusted according to actual needs. This enables the massage head 10 to apply precise pressure to different areas such as the shoulders, neck, waist, buttocks, and thighs, thereby meeting user needs and improving the user experience. Furthermore, the adjustable massage head 10 prevents excessive pressure on specific areas, thus avoiding muscle injury and protecting the user's health. Moreover, the movement of the massage head 10 expands the massage coverage area, relieving fatigue in large areas of muscles and further enhancing massage comfort and effectiveness.

[0042] According to the embodiments of the present invention, the massage head assembly 100 is provided with a connector 30, which can adjust the position of the massage head 10 according to actual needs, thereby meeting the user's usage needs, improving the user experience, and at the same time, avoiding excessive local pressure that could lead to muscle injury, thus protecting the user's health.

[0043] According to some embodiments of this utility model, refer to Figure 2 , Figure 3 and Figure 5 Connector 30 is wound around the second direction (e.g.) Figure 2 The first axis extending in the left-right direction (as shown) is rotatably connected to the drive shaft 20, and / or, the connector 30 is rotatably connected around a third direction (such as...) Figure 2 The second axis extending in the vertical direction (as shown) is rotatably connected to the drive shaft 20, and the first direction (as shown) Figure 2 The front and back directions shown), the second direction and the third direction are perpendicular to each other.

[0044] In this way, the connector 30 can rotate relative to the drive shaft 20 in two directions. The rotational displacements in the two directions are superimposed, which allows the massage head 10 to move in a plane perpendicular to the first direction, thereby ensuring the range of movement of the massage head 10 and effectively guaranteeing the user's experience.

[0045] For example, such as Figure 2 , Figure 3 and Figure 5 As shown, the connector 30 is rotatably connected to the drive shaft 20 about a first axis extending in the left-right direction, and the connector 30 is rotatably connected to the drive shaft 20 about a second axis extending in the up-down direction.

[0046] According to some embodiments of this utility model, refer to Figure 2 , Figure 3 and Figure 6 The massage head assembly 100 includes a connecting seat 40, which is fixed to a drive shaft 20. A connecting member 30 is rotatably mounted on the connecting seat 40 around a first sphere. Thus, the connection seat 40 is fixed to the drive shaft 20, facilitating the connection of the connecting member 30 to the drive shaft 20, thereby reducing assembly difficulty. Simultaneously, the connecting member 30 is rotatable relative to the connecting seat 40. Since the connecting seat 40 is fixed to the drive shaft 20, the connecting member 30 can rotate relative to the drive shaft 20, thereby enabling normal movement of the massage head 10. Preferably, the connecting seat 40 and the drive shaft 20 are fastened together with bolts, facilitating maintenance and replacement of the connecting seat 40.

[0047] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 4The end of the connector 30 facing the drive shaft 20 (e.g.) Figure 4 The rear end of the connector 30 shown forms a rotating part 31, the outer surface of which is spherical, and the connecting seat 40 is along a first direction (e.g. Figure 3 The sleeve (shown in the front-to-back direction) extends into a sleeve, and the rotating part 31 is rotatably fitted into the connecting seat 40.

[0048] Therefore, the rotating part 31 is provided to facilitate the cooperation between the rotating part 31 and the connecting seat 40. At the same time, the reasonable structure of the outer surface of the rotating part 31 can reduce the frictional resistance when the rotating part 31 rotates relative to the connecting seat 40, thereby ensuring the smoothness and stability of the rotation of the rotating part 31. Furthermore, the reasonable extension direction of the connecting seat 40 can limit the rotation space for cooperation with the rotating part 31 inside the sleeve without additional processing, thereby reducing the processing steps of the sleeve and reducing production costs.

[0049] For example, such as Figure 2 , Figure 3 and Figure 4 As shown, the rear end of the connector 30 forms a rotating part 31, which is formed into a spherical structure. The connector 40 extends into a sleeve in the vertical direction, and the rotating part 31 is rotatably fitted inside the sleeve.

[0050] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 4 Connector 40 in the second direction (e.g.) Figure 3 Limiting holes 41 are formed on both opposite sidewalls in the left-right direction (as shown), and the second direction and the first direction (as shown) Figure 3 (as shown in the front-back direction) is perpendicular, and the rotating part 31 is provided with a limiting shaft 311 extending in the second direction. The limiting shaft 311 is rotatably fitted in the limiting hole 41 around the first axis extending in the second direction.

[0051] In this way, the limiting hole 41 and the limiting shaft 311 cooperate to both realize the rotation of the rotating part 31 within the sleeve and limit the rotation direction of the rotating part 31. At the same time, the structure of the limiting hole 41 and the limiting shaft 311 is simple, easy to process, and facilitates improved processing efficiency. Furthermore, the cooperation of two limiting holes 41 and two limiting shafts 311 can improve the rotational stability of the rotating part 31, thereby ensuring the rotational stability of the massage head 10 relative to the drive shaft 20.

[0052] For example, such as Figure 2 , Figure 3 and Figure 4As shown, the connecting seat 40 has limiting holes 41 on the two side walls opposite to each other in the left and right directions. The limiting holes 41 penetrate the sleeve in the left and right directions. The rotating part 31 has limiting shafts 311 extending in the left and right directions on the left and right sides. The limiting shafts 311 are fitted into the limiting holes 41 so that the limiting shafts 311 are rotatably fitted into the limiting holes 41 around the first axis extending in the left and right directions.

[0053] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 4 The limiting hole 41 is along the first direction (e.g.) Figure 3 The front-to-back direction shown) extends into a long strip shape, and the limiting shaft 311 extends around a third direction (such as...). Figure 3 The second axis (extending in the vertical direction as shown) is oscillatingly disposed within the limiting hole 41.

[0054] In this way, the direction of the extension of the limiting hole 41 is reasonable, and the limiting shaft 311 can rotate around the second axis within the limiting hole 41. Therefore, it can ensure that the rotating part 31 can rotate around the second axis, and improve the functional integration of the limiting hole 41. At the same time, only the limiting hole 41 is set to realize the rotation of the limiting shaft 311 around the first axis and the second axis, thereby reducing the processing steps and reducing production costs.

[0055] For example, such as Figure 2 , Figure 3 and Figure 4 As shown, the limiting hole 41 extends in a long strip shape along the front-back direction. The limiting hole 41 is an oblong hole. The limiting shaft 311 is oscillatingly disposed in the limiting hole 41 around the second axis extending in the up-down direction.

[0056] According to some embodiments of this utility model, refer to Figure 2 , Figure 3 and Figure 6 The end of the connector 30 facing the massage head 10 (e.g.) Figure 3 The front end of the connector 30 shown is provided with a connecting rod 32, and the connecting seat 40 faces the end of the massage head 10 (e.g., Figure 3 The inner peripheral wall of the front end of the connecting seat 40 shown is provided with a limiting surface 42. The limiting surface 42 extends into a conical surface along the circumference of the connecting seat 40. In the direction from the massage head 10 to the connector 30, the limiting surface 42 extends radially inward along the connecting seat 40. The connecting rod 32 is located radially inside the limiting surface 42.

[0057] In this way, the connecting rod 32 abuts against the limiting surface 42, which limits the tilt angle of the connecting rod 32, thereby limiting the rotation angle of the rotating part 31 within the sleeve. This ensures that the massage head 10 can rotate to a suitable angle, improving the user experience. At the same time, the limiting surface 42 extends in a reasonable direction, allowing the connecting rod 32 to abut against the limiting surface 42 at any position. This ensures that the tilt angle of the connecting rod 32 is uniform at any position, further improving the rationality of the rotation angle of the massage head 10.

[0058] In addition, the connecting rod 32 is positioned reasonably, which can ensure that the connecting rod 32 can always abut against the limiting surface 42, thereby ensuring that the connecting rod 32 can cooperate normally with the limiting surface 42.

[0059] For example, such as Figure 2 , Figure 3 and Figure 6 As shown, the front end of the connector 30 is provided with a connecting rod 32, and the inner peripheral wall of the front end of the connector 40 is provided with a limiting surface 42. The limiting surface 42 extends into a conical surface along the circumference of the connector 40. In the direction from front to back, the limiting surface 42 extends inwardly along the radial direction of the connector 40, and the connecting rod 32 is located in the radial interior of the limiting surface 42.

[0060] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 6 The angle between the limiting surface 42 and the horizontal plane perpendicular to the axis of the drive shaft 20 is greater than or equal to 45°. Therefore, by limiting the angle of the limiting surface 42, the rotation angle of the connecting rod 32 can be limited, thereby limiting the rotation angle of the massage head 10 within a reasonable range, thus ensuring the user's experience.

[0061] It should be noted that if the angle between the limiting surface 42 and the horizontal plane perpendicular to the axis of the drive shaft 20 is greater than or equal to 45°, then the rotation angle of the connecting rod 32 relative to the connecting seat 40 is less than or equal to 45°.

[0062] For example, such as Figure 2 , Figure 3 and Figure 6 As shown, the angle between the limiting surface 42 and the horizontal plane perpendicular to the axis of the drive shaft 20 can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80° or 85°.

[0063] According to some embodiments of this utility model, refer to Figure 2 , Figure 3 and Figure 5 The end of the connector 30 facing the massage head 10 (e.g.) Figure 3The connector 30 shown has a connecting rod 32 at its front end. The massage head 10 has a connecting groove that mates with the connecting rod 32. The connecting rod 32 extends into the connecting groove so that the massage head 10 and the connector 30 are inserted and fixed together. Therefore, the plug-in connection structure is simple and facilitates the insertion and mating of the massage head 10 and the connector 30. At the same time, it facilitates the maintenance and replacement of the massage head 10 and reduces maintenance costs.

[0064] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 5 The massage head assembly 100 also includes an elastic element 50, which is sleeved on the connecting rod 32. The connecting rod 32 is connected to the massage head 10 via the elastic element 50. Thus, the massage head 10 can move along the extension direction of the connecting rod 32 via the elastic element 50, thereby adaptively adjusting the support force of the massage head 10 on the user's body, and ensuring the massage effect.

[0065] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 5 The massage head assembly 100 includes: a support plate 60, which is sleeved on the connecting rod 32, and elastic elements 50 at both ends (e.g., Figure 2 The front and rear ends of the elastic element 50 shown abut against the support plate 60 and the massage head 10, respectively. Thus, the support plate 60 provides a connection point for the elastic element 50 to connect with the connecting rod 32, facilitating the connection between the elastic element 50 and the connecting rod 32. Simultaneously, the support plate 60, in conjunction with the massage head 10, allows the elastic element 50 to store and release elastic force, enabling the massage head 10 to reciprocate along the extension direction of the connecting rod 32, thereby improving the user experience.

[0066] For example, such as Figure 2 , Figure 3 and Figure 5 As shown, the support plate 60 is sleeved on the connecting rod 32, the rear end of the elastic element 50 is supported on the support plate 60, and the front end of the elastic element 50 abuts against the massage head 10. Preferably, the elastic element 50 is a spring, which has a simple structure, low cost, and is easy to use in mass production.

[0067] When the user squeezes the massage head 10 backward, the massage head 10 compresses the elastic element 50, causing the massage head 10 to move backward. When the user stops squeezing the massage head 10, the elastic element 50 releases its elasticity and pushes the massage head 10 forward, completing the reset of the massage head 10.

[0068] Furthermore, such as Figure 1 and Figure 2As shown, the massage head assembly 100 includes: a drive member 70, two drive shafts 20, the two drive members 70 are arranged at intervals in the left and right direction, the left and right ends of the drive member 70 are respectively connected to the two drive shafts 20, and the number of massage heads 10 is two, with each massage head 10 corresponding to a drive shaft 20, so that one drive member 70 can drive two massage heads 10 to rotate.

[0069] The seat according to a second aspect embodiment of the present utility model, referring to... Figure 1 , Figure 2 and Figure 3 This includes the massage head assembly 100 of the first aspect of this embodiment.

[0070] According to the embodiments of the present invention, the seat, by providing the massage head assembly 100 of the first aspect embodiment and the connecting member 30, can adjust the position of the massage head 10 according to actual needs, thereby meeting the user's usage needs and improving the user experience. At the same time, it can avoid excessive local pressure that could lead to muscle injury, thereby protecting the user's health.

[0071] Furthermore, such as Figure 1 and Figure 2 As shown, multiple massage head assemblies 100 can be installed on the seat, which can massage multiple parts of the user's body, thereby improving the user experience.
