[0018] With the development of the massage equipment industry, more and more diverse massage devices are being widely sought after by users. In this field, the tapping and reciprocating motion of most massage devices is limited to a fixed stroke and cannot change the tapping depth according to the needs of the human body. This is due to the limitation of the movement direction of the drive device inside the massage device, which can only move within a fixed stroke, thereby reducing the comfort and flexibility of the massage device.

[0019] like Figures 1-5 As shown, Figure 1 This is a schematic diagram of the structure of the driving device according to an embodiment of this application.

[0020] The purpose of this application is to overcome the defects and deficiencies in the prior art and provide a driving device 1. This driving device 1 aims to solve the problems of single driving direction and limited driving stroke in related technologies. It includes a first driving module 10 and a second driving module 11. The first driving module 10 includes a first driving component 100 and a first driven component 101. In some embodiments, the first driving component 100 and the first driven component 101 can be connected by, but is not limited to, a gear drive connection. The first driving component 100 and the first driven component 101 are arranged adjacent to each other. Adjacent arrangement means that the first driving component 100 and the first driven component 101 are arranged on opposite sides of the central axis of the driving device 1. The first driving component 100 drives the first driven component 101 to move. In some embodiments, when the first driving component 100 rotates or reciprocates, it pushes the first driven component 101 to move through the contact surface or connecting member. The first driven component 101 drives the second driven component 1110 along a first direction ( Figure 1 The first direction is the direction of the axis extension of the second drive component 110.

[0021] The second drive module 11 includes a second drive component 110 and a second driven component 111. A first driven component 101 is connected to the second driven component 111. The second drive component 110 drives the second driven component 111. In some embodiments, the second driven component 111 can be driven simultaneously by both the first drive component 100 and the second drive component 110. The second driven component 111 can be moved in a first direction by the first driven component 101, and it can also be moved in a second direction by the second drive component 110. Figure 1 The second direction is the direction of rotation around the axis of the second drive component 110, and the direction of rotation can be clockwise or counterclockwise.

[0022] This application utilizes the coordinated operation of the first drive module 10 and the second drive module 11. The first drive component 100 drives the first driven component 101 to move along a first direction, and the second drive component 110 drives the second driven component 111 to move along a second direction. Through structural design, the first driven component 101 of the drive device 1 can move in different directions, thereby enhancing the diversity of drive directions and the controllability of drive stroke of the drive device 1. This improves the comfort and precision of the massage provided by the device driven by the drive device 1. At the same time, the modular drive module design simplifies the internal structure, shortens the R&D cycle, reduces production costs, and improves product consistency and stability.

[0023] The first driven component 101 includes a first driven member 1010, a fixing member 1012, and a driving mating member 1011. The first driven member 1010 is the core moving component that receives power from the first driving module 10 and generates displacement. The fixing member 1012 serves as a support or guide structure and engages with the second driven member 1010. In some embodiments, the driving mating member 1011 may be, but is not limited to, a guide structure with threaded teeth. The first driven member 1010 is located outside the driving mating member 1011 and engages with it in a helical manner. The first driven member 1010 can... The driven wheel is provided with threads on the side facing the drive mating member 1011, and the fixing member 1012 is a snap-fit ​​member that connects to the first driven member 1010. The fixing member 1012 is disposed on the side of the first driven member 1010 away from the drive mating member 1011. The second driven assembly 111 includes a second driven member 1110, which is disposed between the first driven member 1010 and the fixing member 1012. The fixing member 1012 is used to fix the second driven member 1110 to the first driven member 1010. The second driven member 1110 may be, but is not limited to, a snap-fit ​​block.

[0024] The first drive assembly 100 includes a first drive connector 1000 and a first drive member 1001. The first drive connector 1000 forms a helical engagement with the first driven member 1010, and the first drive connector 1000 is connected to the first driven member 1010. In some embodiments, the first drive member 1001 is the source of providing the original power. The first drive member 1001 may be, but is not limited to, a rotary motor or a similar rotary power source, such as a geared motor. The first drive connector 1000 is the core component for power transmission and motion mode conversion. One end of it is connected to the first drive member 1001 to receive rotary power, and the other end engages with the first driven member 1010. The first drive connector 1000 may be, but is not limited to, a gear. The first driving connector 1000 and the first driven component 1010 form a helical fit, which means that there is a threaded connection between the two. When the first driving connector 1000 and the first driven component 1010 are helically fitted, a position will also be generated in the first direction, so that the rotational motion of the first driving connector 1000 can be converted into the linear reciprocating motion of the first driven component 1010.

[0025] A fixing groove 1013 is formed between the first driven member 1010 and the fixing member 1012. The second driven member 1110 is disposed in the fixing groove 1013. The fixing groove 1013 is a groove for accommodating the second driven member 1110. There can be a gap or a tight connection between the second driven member 1110 and the side wall of the fixing groove 1013. Since the second driven member 1110 only needs to receive the linear displacement in the first direction during the spiral movement of the first driven member 1010 and the fixing member 1012, it can be flexibly set. The first driving member 1001 drives the first driven member 1010 to move linearly in the first direction by driving the first driving connector 1000 to rotate and drive the first driven member 1010 to move spirally on the driving mating member 1011.

[0026] The drive device 1 also includes a bracket 12, and a second drive assembly 110 is disposed on the bracket 12. The bracket 12 may be, but is not limited to, a hollow support member with protruding supports. The second drive assembly 110 rotates around the bracket 12. The second drive assembly 110 includes a rotating member 1100 and a rotating mating member 1101. The rotating mating member 1101 may be, but is not limited to, a stator and a magnet. The rotating member 1100 may be, but is not limited to, a rotating shaft and a bearing. A protrusion 120 is provided inside the bracket 12, and a receiving groove 121 is provided inside the protrusion 120. The rotating mating member 1101 is disposed on the bracket 12. In some embodiments, the stator of the rotating mating member 1101 has a hollow structure surrounding the protrusion 120, and a magnet is disposed on the side of the stator away from the protrusion 120. The rotating member 1100 is disposed at the central axis position of the receiving groove 121. The rotating member 1100 is connected to the second driven member 1110. The rotating member 1100 is used to drive the rotating member 1100 to rotate in the second direction, thereby driving the second driven component 111 to rotate in the second direction. That is, the rotating member 1100 is used to drive the second driven component 111 to rotate.

[0027] The drive device 1 also includes a drive bracket 13, which includes a first support portion 130 and a second support portion 131. The first support portion 130 and the second support portion 131 are arranged side by side. The first drive assembly 100 is disposed on the first support portion 130, and the bracket 12 is disposed on the second support portion 131. In some embodiments, the first support portion 130 and the second support portion 131 are integrally formed shell structures. The first support portion 130 is mainly used to support and fix the core moving parts of the first drive assembly 100, such as motors, eccentric wheel mechanisms, or transmission linkages, to ensure that the power source and motion conversion mechanism are stably installed. The second support portion 131 is used to install the bracket 12, thereby stabilizing the operation and rotation of the second drive assembly 110 inside the bracket 12. The first support portion 130 and the second support portion 131 are arranged adjacent to each other on the left and right sides, so that the first drive assembly 100 and the second drive assembly 110 will not affect each other when they operate simultaneously or indirectly. In some embodiments, a vibration damping device is also provided on the side of the drive bracket 13 away from the first drive assembly 100 and the bracket 12 for further vibration damping during operation.

[0028] The first drive assembly 100 is arranged parallel to the central axis of the bracket 12, and the bracket 12 is coaxially arranged with the second drive module 11 and the first driven component 1010. In some embodiments, the force direction or motion axis of the first drive assembly 100 is consistent with or parallel to the geometric center axis of the bracket 12. This arrangement is conducive to the direct transmission of force and reduces off-center load. The coaxial arrangement of the bracket 12 with the second drive module 11 and the first driven component 1010 indicates that the second drive module 11 and the first driven component 1010 are spatially distributed around the central axis of the bracket 12, or their motion axes coincide with the central axis of the bracket 12. This coaxial design makes the power transmission path short and straight, reducing interference and wear caused by eccentricity or non-collinearity.

[0029] The first drive module 10 includes two first driven components 101, and the second drive module 11 includes two second driven components 111. The two first driven components 101 and the two second driven components 111 are disposed at both ends of the connecting member of the rotating member 1100. The first drive component 100 includes two drive mating components 1011. In some embodiments, the drive device 1 is a dual-head design, and the rotating heads on both sides are driven simultaneously by one first drive component 1001 and the second drive component 110. Therefore, one first drive component 1001 is connected to two drive mating components 1011 at the same time, so that the two first driven components 101 can be moved simultaneously by one first drive component 1001. At the same time, one second drive component 110 is also disposed. At the same time, the two ends of the rotating member 1100 are respectively connected to the two second driven components 111, so that when the rotating member 1100 rotates, it drives the two second driven components 111 to rotate simultaneously.

[0030] In some embodiments, the drive device 1 is a dual-head design, with two first drive members 1001 and two drive components 110, which drive the rotating heads on both sides respectively. Therefore, the two first drive members 1001 are respectively connected to two drive mating members 1011 and controlled separately according to different needs. Thus, the two first drive members 1001 drive the two first driven components 101 to move respectively. Simultaneously, two second drive components 110 are also provided, with both ends of the two rotating members 1100 connected to the two second driven components 111 respectively, so that when the rotating members 1100 rotate, they drive the two second driven components 111 to rotate respectively. The drive device 1 also includes a connector 14, which is disposed at the end of the rotating member 1100. The connector 14 is used to connect to an external device and is provided with a guide groove 140. The second driven member 1110 is connected to the connector through a connecting feature 141, which can move within the guide groove 140. The connector is a structural component in the drive device 1 that is directly connected to an external massage component (such as a massage head or linkage mechanism). The connector has a guide groove 140 inside or on its surface. The guide groove 140 is a long strip or curved receiving space used to guide and restrict the movement trajectory of the internal component. The second driven member 1110 is a moving component that cooperates with the connector. The connecting feature 141 is a protruding or extended part on the driving member, such as a pin, boss, or slider. It is embedded in the guide groove 140 of the connector 14, so that the second driven member 1110 and the connector form a sliding or rolling cooperation relationship.

[0031] like Figure 1-6 As shown, Figure 6 This is a simplified structural diagram of the massage device according to an embodiment of this application. This application also provides a massage device 20, including the aforementioned drive device 1. The drive device 1 of the massage device is connected to the massage head, so that the user can appropriately adjust the massage depth according to the needs of different parts of the body, thereby improving the experience. It is also a multi-head massage head adjustable stroke module designed to meet the needs of different user body shapes, thereby improving user adaptability. At the same time, in order to meet the needs of different appearances, different drive modules are designed to shorten the research and development cycle and reduce production costs, thereby reducing the cost of redeveloping for each different appearance, and improving the stability and consistency of the product.
