[0034] 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.

[0035] The following is a reference appendix. Figure 1-8 Description of a massage head assembly 100 according to an embodiment of the present invention.

[0036] 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.

[0037] Specifically, the drive shaft 20 is along the first direction (e.g., Figure 3 The drive shaft 20 extends in the front-to-back direction and is connected to the massage head 10, for driving the massage head 10 to rotate about the axis of the drive shaft 20; the connector 30 is connected between the drive shaft 20 and the massage head 10, and the connector 30 rotates along the second direction (e.g., in the front-to-back direction shown) and is connected to the massage head 10 for driving the massage head 10 to rotate about the axis of the drive shaft 20; Figure 3 The first axis extending in the vertical direction (as shown) can rotate relative to the drive shaft 20, and the massage head 10 rotates around a third axis (such as...) Figure 3 The second axis extending in the left-right direction (as shown) can rotate relative to the connector 30, and the first direction, the second direction and the third direction are perpendicular to each other.

[0038] 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-back direction. The rear end of the massage head 10 is connected to the front end of the drive shaft 20 via a connector 30. The connector 30 is located between the drive shaft 20 and the massage head 10. The front end of the connector 30 is connected to the massage head 10, and the rear end of the connector 30 is connected to the drive shaft 20. The connector 30 can rotate relative to the drive shaft 20 about a first axis extending in the up-down direction, and the massage head 10 can rotate relative to the connector 30 about a second axis extending in the left-right direction.

[0039] 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 massage head 10 is not in the correct position, the user applies a force to the massage head 10. The force causes the massage head 10 to rotate up and down relative to the connector 30 around the second axis. The force can also cause the connector 30 to rotate left and right around the first axis through the massage head 10, so that the massage head 10 can rotate left and right, thereby realizing the rotation of the massage head 10 in the up and down direction and the left and right direction.

[0040] The massage head assembly 100 of this utility model is provided with a connector 30. Through the cooperation of the connector 30 and the drive shaft 20, the position of the massage head 10 in the left and right directions can be adjusted. Through the cooperation of the connector 30 and the massage head 10, the position of the massage head 10 in the up and down directions can also be adjusted. Therefore, the position of the massage head 10 can be adjusted according to actual needs, so that the massage head 10 can apply force precisely to different parts of the user's body, thereby meeting the user's needs and improving the user experience. At the same time, the cooperation of the connector 30, the drive shaft 20 and the massage head 10 can realize the adjustment of the massage head 10 in the up and down and left and right directions. This structure is simple and has good stability, thus ensuring the smooth movement of the massage head 10.

[0041] Furthermore, the massage head 10 is adjustable, which can prevent excessive local pressure from causing muscle injury and thus protect the user's health. In addition, by moving the massage head 10, the massage coverage area can be expanded, thereby relieving large-area muscle fatigue and improving massage comfort and effect.

[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 3 , Figure 4 , Figure 5 and Figure 7 The massage head assembly 100 may further include: a connecting seat 40, which is fixed to the drive shaft 20, with the connecting seat 40 facing the side of the connector 30 (e.g., Figure 7 The front side of the connecting seat 40 shown has two first protrusions 41, and the two first protrusions 41 are arranged along the second direction (such as...). Figure 7 The two first bosses 41 are arranged at intervals in the vertical direction shown. Each of the two first bosses 41 has a first shaft hole 411. The connector 30 is provided with a first rotating shaft 31 extending in the second direction. The two ends of the first rotating shaft 31 are rotatably fitted into the two first shaft holes 411.

[0044] In this way, the first boss 41 is provided on the connecting seat 40, which not only facilitates the arrangement of the first boss 41, but also facilitates the rotatable connection between the connecting member 30 and the connecting seat 40 through the first boss 41. At the same time, the first shaft hole 411 of the two first bosses 41 cooperates with the first rotating shaft 31, which can ensure the stability of the rotation of the connecting member 30 relative to the connecting seat 40, thereby preventing the first rotating shaft 31 from disengaging from the first shaft hole 411, and thus ensuring the stability of the system.

[0045] In addition, the structure of the first boss 41 is simple and easy to process, which can improve processing efficiency. Furthermore, the two first bosses 41 define the installation space, which can facilitate the assembly of the connector 30 and support the connector 30 in the first direction, effectively preventing interference between the connector 30 and the drive shaft 20.

[0046] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the connecting seat 40 is fixedly connected to the drive shaft 20. The front side of the connecting seat 40 is provided with two first protrusions 41. The first protrusions 41 extend forward and are arranged at intervals in the vertical direction. Each first protrusion 41 has a first shaft hole 411 formed on it. The first shaft hole 411 passes through the first protrusion 41 in the vertical direction. The rear side of the connecting member 30 is provided with a first rotating shaft 31. The first rotating shaft 31 extends in the vertical direction and its two ends extend into the corresponding first shaft hole 411.

[0047] According to some embodiments of this utility model, refer to Figure 2 , Figure 4 , Figure 5 and Figure 8 The massage head 10 faces the side of the connector 30 (e.g.) Figure 8 The massage head 10 shown has two second protrusions 11 on its rear side, and the two second protrusions 11 are arranged along a third direction (such as...). Figure 8 The second protrusions 11 are arranged at intervals in the left-right direction (as shown), and each of the two second protrusions 11 has a second shaft hole 111. The connector 30 is provided with a second rotating shaft 32 extending in the third direction. The two ends of the second rotating shaft 32 (as shown) Figure 8 The left and right ends of the second rotating shaft 32 shown are rotatably fitted into the two second shaft holes 111.

[0048] In this way, the second protrusion 11 on the massage head 10 can facilitate the arrangement of the second protrusion 11 and facilitate the rotatable connection between the massage head 10 and the connector 30 through the second protrusion 11. At the same time, the second shaft hole 111 of the two second protrusions 11 cooperates with the second rotating shaft 32 to ensure the stability of the rotation of the massage head 10 relative to the connector 30, thereby preventing the second rotating shaft 32 from disengaging from the second shaft hole 111, and thus ensuring the stability of the system.

[0049] In addition, the second boss 11 has a simple structure and is easy to process, which can improve processing efficiency. Furthermore, the two second bosses 11 define the installation space, which can facilitate the assembly of the connector 30 and support the connector 30 in the first direction, effectively preventing interference between the connector 30 and the massage head 10.

[0050] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the massage head 10 has two second protrusions 11 on its rear side. The second protrusions 11 extend rearward and are arranged at intervals in the left-right direction. Each second protrusion 11 has a second shaft hole 111 formed on it. The second shaft hole 111 passes through the second protrusion 11 in the left-right direction. The connector 30 has a second rotating shaft 32 on its front side. The second rotating shaft 32 extends in the left-right direction and its two ends extend into the corresponding second shaft hole 111.

[0051] According to some embodiments of this utility model, refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 The rotation angle of the connector 30 around the first axis is less than or equal to 45°, and / or the rotation angle of the massage head 10 around the second axis is less than or equal to 45°. Therefore, by limiting the rotation angles of the connector 30 and the massage head 10, the rotation angle of the massage head 10 relative to the drive shaft 20 can be kept within a reasonable range. This ensures a good user experience while preventing excessively large rotation angles that would prevent the massage head 10 from effectively conforming to the user's body, and also preventing excessively small rotation angles that would affect the range of motion of the massage head 10. Thus, the massage head 10 can meet the user's needs.

[0052] For example, such as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the rotation angle of the connector 30 around the first axis can be 45°, 40°, 35°, 30°, 25°, 20°, 15°, 10° or 5°, and the rotation angle of the massage head 10 around the second axis can be 45°, 40°, 35°, 30°, 25°, 20°, 15°, 10° or 5°.

[0053] According to some embodiments of this utility model, refer to Figure 3 , Figure 4 and Figure 6 The end face of the connector 30 facing the drive shaft 20 (e.g.) Figure 4 The rear end face of the connector 30 shown is formed as a first clearance surface 33, and in a third direction (e.g., from the middle of the first clearance surface 33 toward the first clearance surface 33) Figure 6 In the direction of the left and right sides shown, the first clearance surface 33 extends at an angle toward gradually moving away from the drive shaft 20.

[0054] Thus, by setting the first clearance surface 33, a clearance portion can be formed between the connector 30 and the drive shaft 20. During assembly or movement, this prevents the connector 30 from colliding and interfering with the drive shaft 20, thereby ensuring that the connector 30 can rotate normally relative to the drive shaft 20. Furthermore, the extension direction of the first clearance surface 33 is reasonable, maximizing the rotational space between the connector 30 and the drive shaft 20. In addition, the structure of the first clearance surface 33 is simple and easy to manufacture, thereby improving processing efficiency.

[0055] For example, such as Figure 3 , Figure 4 and Figure 6 As shown, the end face of the rear end of the connector 30 is formed as a first clearance surface 33. In the direction from the middle of the first clearance surface 33 toward the two sides of the first clearance surface 33 in the left-right direction, the first clearance surface 33 extends obliquely away from the drive shaft 20.

[0056] According to some optional embodiments of the present invention, refer to Figure 3 , Figure 4 and Figure 6 The first avoidance surface 33 includes the third-party direction (such as...) Figure 6 The first segment 331, the second segment 332, and the third segment 333 are sequentially connected in the left-right direction (as shown). The second segment 332 is in the first direction (as shown). Figure 6The arc surface protruding towards the drive shaft 20 in the front-back direction (as shown) has two planar sections, the first section 331 and the third section 333, and the distance between the first section 331 and the third section 333 gradually increases in the third direction from the drive shaft 20 toward the massage head 10.

[0057] In this way, the extension directions of the first segment 331 and the third segment 333 are reasonable, so that the first clearance surface 33 can extend in an inclined direction gradually away from the drive shaft 20. At the same time, the second segment 332 is an arc surface. If the connector 30 contacts the drive shaft 20, the load on the arc surface is distributed in a progressive manner, which can avoid local stress concentration and reduce the friction between the connector 30 and the drive shaft 20, thereby effectively protecting the connector 30 and the drive shaft 20.

[0058] For example, such as Figure 3 , Figure 4 and Figure 6 As shown, the first clearance surface 33 includes a first segment 331, a second segment 332, and a third segment 333 connected sequentially in the left-right direction. The first segment 331 is located to the right of the second segment 332, and the third segment 333 is located to the left of the second segment 332. The second segment 332 is an arc-shaped surface that protrudes towards the drive shaft 20 in the front-rear direction. Both the first segment 331 and the third segment 333 are planar, and from back to front, the first segment 331 extends inclined to the right and forward, while the third segment 333 extends inclined to the left and forward, so that the distance between the first segment 331 and the third segment 333 gradually increases in the left-right direction. Preferably, the second segment 332 is formed by a chamfering process, which is simple and efficient, thereby improving processing efficiency.

[0059] According to some embodiments of this utility model, refer to Figure 3 , Figure 4 and Figure 5 The end face of the connector 30 facing the massage head 10 (e.g.) Figure 4 The front end face of the connector 30 shown is formed as a second clearance surface 34, and the second clearance surface 34 is oriented in a second direction (e.g., from the middle of the second clearance surface 34 toward the second clearance surface 34) Figure 5 In the direction of the two sides of the upper and lower direction shown, the second clearance surface 34 extends in an inclined direction away from the massage head 10.

[0060] Thus, by providing the second clearance surface 34, a clearance area can be formed between the connector 30 and the massage head 10. During assembly or movement, this prevents the connector 30 from colliding and interfering with the massage head 10, thereby ensuring that the massage head 10 can rotate normally relative to the connector 30. Furthermore, the extension direction of the second clearance surface 34 is reasonable, maximizing the rotational space between the connector 30 and the massage head 10. In addition, the structure of the second clearance surface 34 is simple and easy to manufacture, thereby improving processing efficiency.

[0061] For example, such as Figure 3 , Figure 4 and Figure 5 As shown, the front end face of the connector 30 is formed as a second clearance surface 34. In the direction from the middle of the second clearance surface 34 toward the two sides of the second clearance surface 34 in the vertical direction, the second clearance surface 34 extends obliquely away from the massage head 10.

[0062] According to some optional embodiments of the present invention, refer to Figure 3 , Figure 4 and Figure 5 The second avoidance surface 34 includes the second direction (e.g.) Figure 5 The first part 341, the second part 342, and the third part 343 are connected sequentially in the vertical direction (as shown). The second part 342 is in the first direction (e.g., Figure 1 The first part 341 and the third part 343 are both planar surfaces, and the distance between the first part 341 and the third part 343 gradually increases in the second direction from the massage head 10 toward the drive shaft 20.

[0063] In this way, the extension directions of the first part 341 and the third part 343 are reasonable, so that the second clearance surface 34 can extend in an inclined direction gradually away from the massage head 10. At the same time, the second part 342 is an arc surface. If the connector 30 contacts the massage head 10, the load on the arc surface is distributed in a progressive manner, which can avoid local stress concentration and reduce the friction between the connector 30 and the massage head 10, thereby effectively protecting the connector 30 and the part.

[0064] For example, such as Figure 3 , Figure 4 and Figure 6 As shown, the second clearance surface 34 includes a first part 341, a second part 342, and a third part 343 connected sequentially in the vertical direction. The first part 341 is located above the second part 342, and the third part 343 is located below the second part 342. The second part 342 is an arc-shaped surface that protrudes towards the massage head 10 in the front-back direction. Both the first part 341 and the third part 343 are planar. From front to back, the first part 341 extends upward and backward at an angle, while the third part extends downward at an angle, causing the distance between the first part 341 and the third part 343 to gradually increase in the left-right direction. Preferably, the second part 342 is formed by a chamfering process, which is simple and efficient, thereby improving processing efficiency.

[0065] According to some embodiments of this utility model, refer to Figure 3 , Figure 4 and Figure 7 One end of the drive shaft 20 (e.g. Figure 7 The front end of the drive shaft 20 shown is provided with a connecting flange 21, and the end of the connecting seat 40 opposite to the massage head 10 (such as...) Figure 7 The rear end of the connecting seat 40 shown is provided with a fixed flange 42, and the connecting flange 21 and the fixed flange 42 are connected by fasteners. Thus, by setting the connecting flange 21 and the fixed flange 42, a fixed position can be provided for the drive shaft 20 and the connecting seat 40, which facilitates operation. At the same time, this connection is simple, convenient to operate, and can improve connection efficiency.

[0066] For example, such as Figure 3 , Figure 4 and Figure 7 As shown, the front end of the drive shaft 20 is provided with a connecting flange 21, and the rear end of the connecting seat 40 is provided with a fixing flange 42. The connecting seat 40 and the fixing flange 42 are connected by bolts. Preferably, multiple bolts are provided to improve the fixing strength.

[0067] According to some embodiments of this utility model, refer to Figure 1 , Figure 2 and Figure 3 The massage head assembly 100 also includes a drive mechanism 50, which includes a drive motor and a transmission assembly. The drive motor is connected to the drive shaft 20 through the transmission assembly and is used to drive the drive shaft 20 to rotate. There are two drive shafts 20, which are respectively arranged on opposite sides of the drive mechanism 50. The massage head 10 and the connector 30 are connected to the drive shaft 20 one by one.

[0068] In this way, by setting up the transmission component, the drive motor can drive the drive shaft 20 to rotate through the drive transmission component, thereby realizing the rotation of the massage head 10. At the same time, one drive motor can drive two massage heads 10, which can reduce the number of drive motors and effectively reduce the size of the massage head assembly 100, making it easier to arrange the massage head assembly 100 in the seat.

[0069] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, two drive shafts 20 are respectively arranged on the left and right sides of the drive mechanism 50. The drive mechanism 50 drives the two drive shafts 20 to rotate through the transmission assembly, which in turn drives the two massage heads 10 to rotate.

[0070] The seat according to a second aspect embodiment of the present utility model, referring to... Figure 1 , Figure 2 and Figure 3 It includes: a seat body and a massage head assembly 100 of the first aspect of this embodiment, wherein the massage head assembly 100 is disposed on the seat body.

[0071] For example, the massage head assembly 100 can be installed on the backrest, headrest, and seat cushion of the seat body. Multiple massage head assemblies 100 can operate to provide multi-body, all-round massage to the user, thereby effectively ensuring the massage range and improving the user experience.

[0072] 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.
