Description

Technical Field

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

[0002] Telescopic massagers work by driving a massage head to extend and retract at high frequency, relaxing muscles and relieving muscle fatigue, making them popular among users. Currently, most telescopic massagers on the market have a bushing inside the casing to guide a piston. The piston, which drives the extension and retraction of the massage head, is inserted into the bushing. When the massager is in use, the piston reciprocates steadily along the bushing under the drive of the drive mechanism and the guidance of the bushing. However, in this design, the bushing usually needs to be lubricated to reduce friction. But at high speeds, the oil on the bushing can easily overflow and leak. When the bushing is unlubricated, the piston's reciprocating motion causes it to rub against the bushing, causing it to heat up, wear easily, and generate a lot of noise. After a certain period of use, the bushing will wear down due to heat, creating a gap between it and the piston, further increasing the piston's noise, reducing its stability, and causing the massager to malfunction, thus shortening its lifespan. Furthermore, the piston's stroke cannot be too long, otherwise the bushing may overheat and burn out. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0019] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0020] This utility model mainly proposes a massager, which is primarily used for body massage. The massager includes a housing, and within the housing are a power mechanism, a linkage mechanism, a swing arm mechanism, and a main control board. The linkage mechanism includes a linkage seat, a driving link, and a driven link, which are rotatably connected in sequence. The driven link is used to mount the massage head. The swing arm mechanism includes at least two swing arms, which are rotatably connected in sequence. The first end of the swing arm mechanism is rotatably connected to a support, and the second end is rotatably connected to the driven link. When the massager is in operation, the main control board controls the power mechanism to start. The power mechanism drives the linkage seat to rotate, causing the driving link to swing, thus transmitting a driving force to the driven link. Under the combined action of the driving force of the driving link and the limiting action of the swing arm mechanism, the driven link performs linear reciprocating motion, causing the massage head mounted on the driven link to reciprocate for massage. In this invention, the driven link (equivalent to the piston rod of existing massagers) is limited by a rocker arm mechanism to ensure stable reciprocating motion. Therefore, there is no need to set a bushing to guide the driven link, avoiding the problems of high noise, poor motion stability, short service life, and short stroke caused by using bushings. Furthermore, the various nodes of the rocker arm mechanism are rotatably connected, resulting in low motion resistance, which makes the reciprocating motion of the driven link smoother and extends its service life. Thus, the lifespan of the massager and the stroke of the massage head are effectively improved.

[0021] The specific structure of this massager will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 4 In this embodiment of the invention, the massager includes a housing 10, a power mechanism 20, a linkage mechanism 30, at least one swing arm mechanism 40, and a main control board 60. The power mechanism 20, linkage mechanism 30, at least one swing arm mechanism 40, and main control board 60 are all housed within the housing 10. The power mechanism 20 can be directly mounted and fixed to the housing 10 or indirectly fixed to the housing 10 via an intermediate component. This embodiment uses only one swing arm mechanism 40 as an example; however, in other embodiments, the number of swing arm mechanisms 40 can be two, three, or more.

[0023] In this embodiment, the housing 10 has an opening 102 at one end in the first direction F1. The driven link 33 is located near the end of the housing 10 with the opening 102. This opening 102 is used for mounting and connecting the driven link 33 to the massage head. Alternatively, the end of the driven link 33 furthest from the link seat 31 may extend out of the housing 10 through the opening 102 to connect with the massage head; or the entire driven link 33 may be located inside the housing 10, with one end of the massage head inserted into the housing 10 through the opening 102 to connect with the driven link 33. In the figures of this embodiment, one end of the driven link 33 extends out of the housing 10 through the opening 102, and the driven link 33 and the massage head are detachably connected. This facilitates the installation and removal of the massage head and the driven link, allowing users to quickly change to different massage heads to meet different massage needs. The detachable connection method between the driven link 33 and the massage head is described in the previous embodiments and will not be repeated here.

[0024] In some embodiments, the housing 10 includes a main housing portion 11 extending along a first direction F1 and a handheld portion 12 connected to the side wall of the main housing portion 11. The handheld portion 12 is used for a user to grip the massager for easier use. The power mechanism 20, the linkage mechanism 30, and the swing arm mechanism 40 are disposed within the main housing portion 11, and the opening 102 of the housing 10 is located at one end of the main housing portion 11. The main control board 50 may be disposed within the main housing portion 11 or within the handheld portion 12 of the housing 10.

[0025] The main control board 60 is electrically connected to the power mechanism 20. The main control board 60 controls the operation of the power mechanism 20, including controlling the start, stop, and drive frequency of the power mechanism 20.

[0026] In the description of the embodiments of this utility model, the directions involved include a first direction F1, a second direction F2, and a third direction F3. The first direction F1, the second direction F2, and the third direction F3 are all perpendicular to each other, that is, any two of them are perpendicular (i.e., the first direction F1 is perpendicular to the second direction F2, the first direction F1 is perpendicular to the third direction F3, and the second direction F2 is perpendicular to the third direction F3). It can also be understood that the first direction F1, the second direction F2, and the third direction F3 are the X-axis direction, the Y-axis direction, and the Z-axis direction in the same XYZ coordinate system, respectively.

[0027] Reference Figure 2 , Figure 3 ,as well as Figures 6a to 6cThe linkage mechanism 30 includes a linkage seat 31, a driving link 32, and a driven link 33. The linkage seat 31 is connected to the power mechanism 20, which drives the linkage seat 31 to rotate. The rotation axis of the linkage seat 31 is parallel to the second direction F2. That is, when the power mechanism 20 is working, it drives the linkage seat 31 to rotate around its rotation axis. The first end 321 of the driving link 32 is rotatably connected to the linkage seat 31, and the second end 322 of the driving link 32 is rotatably connected to the driven link 33. The rotation axes of the rotation nodes at both ends of the driving link 32 are parallel to the second direction F2 (the rotation axes of the rotation nodes at both ends of the driving link 32 refer to the rotation axes of the rotation connection positions at both ends of the driving link 32). Therefore, the driven link 33 can only move in a plane perpendicular to the second direction F2. The end of the driven link 33 furthest from the link seat 31 is used to install and connect a massage head, so that the massage head moves together with the driven link 33. The massage head and the driven link 33 can be installed in a detachable manner, or the massage head can be integrally set with the driven link 33. In this embodiment, the massage head and the driven link 33 are detachably connected as an example. In this way, the driven link 33 can be matched with more massage heads of different shapes, sizes or functions to achieve more diversified massage and better meet the different usage needs of different users.

[0028] The detachable connection between the driven link 33 and the massage head can take many forms, such as threaded connection, socket connection, plug connection, snap connection, etc. (Refer to the reference...) Figure 7 and Figure 8 In some embodiments, the driven link 33 has an interface 331 for mounting a massage head at its end away from the link seat. This interface 331 can be a threaded connector (such as a stud or threaded hole), a plug-in connector, a bayonet, or a clamping head. The massage head can be mounted onto the interface 331 using a screw connection, plug connection, or clamping method. For example, if the interface 331 is a stud, when assembling the massage head, the threaded hole on the massage head is threaded into the stud. When the massage head needs to be replaced, the currently connected massage head is unscrewed, and the massage head to be replaced is screwed on.

[0029] In some embodiments, the massager further includes a massage head (not shown) that is detachably connected to the end of the driven link 33 away from the link seat 31. For example, the massage head may be threaded, plugged in, or clamped to the end of the driven link 33 away from the link seat 31.

[0030] Combined with reference Figure 2 , Figure 5 , Figure 6a Zhihe Figure 6cThe rocker arm mechanism 40 includes at least two rocker arms 41 rotatably connected in sequence. The rocker arm mechanism 40 has a head end 401 and a tail end 402. The head end 401 of the rocker arm mechanism 40 refers to the end of the first rocker arm 41 that is not connected to the other rocker arms 41, and the tail end 402 of the rocker arm mechanism 40 refers to the end of the last rocker arm 41 that is not connected to the other rocker arms 41. The head end 401 of the rocker arm mechanism 40 is rotatably connected to the housing 10 (either the head end 401 of the rocker arm mechanism 40 is directly rotatably connected to the housing 10, or the head end 401 of the rocker arm mechanism 40 is rotatably connected to an intermediate component fixed to the housing 10 inside the housing 10). (e.g., bracket 50). The tail end 402 of the rocker arm mechanism 40 is rotatably connected to the driven link 33. The axis of each rotation node of the rocker arm mechanism 40 is parallel to the third direction F3 (the axis of each rotation node of the rocker arm mechanism 40 refers to the rotation axis of each rotational connection position of the rocker arm mechanism 40). Therefore, each rocker arm 41 of the rocker arm mechanism 40 can only move in a plane perpendicular to the third direction F3. The movement trajectory of the tail end 402 of the rocker arm mechanism 40 is also in a plane perpendicular to the third direction F3. In this way, the driven link 33 rotatably connected to the tail end 402 of the rocker arm mechanism 40 is restricted to moving only in a plane perpendicular to the third direction F3. In this embodiment, the rocker arm mechanism 40 includes two rocker arms 41 rotatably connected in sequence as an example. Of course, in other embodiments, the number of rocker arms 41 of the rocker arm mechanism 40 can be three, four or more. The lengths of each rocker arm 41 of the rocker arm mechanism 40 can be the same or different, depending on the structural design requirements of the housing 10.

[0031] In this embodiment of the massager, during operation, the power mechanism 20 drives the connecting rod seat 31 to rotate. The rotation of the connecting rod seat 31 causes the first end 321 of the active connecting rod 32 to swing around the rotation axis of the connecting rod seat 31 (that is, there is a certain distance between the axis of the rotation node of the first end 321 of the active connecting rod 32 and the rotation axis of the connecting rod seat 31, so that the first end 321 of the active connecting rod 32 makes an eccentric motion with the rotation of the connecting rod seat 31). The second end 322 of the active connecting rod 32 is rotatably connected to the driven connecting rod 33, and the driven connecting rod 33 is rotatably connected to the tail end 402 of the swing rod mechanism 40. Next, the driven link 33 is restricted by the swing arm mechanism 40 to move only in a plane perpendicular to the second direction F2, so that the second end 322 of the active link 32 cannot swing with its first end 321. Instead, the force transmitted by the swing of the first end 321 of the active link 32 is converted into a driving force along the first direction F1. Thus, under the limiting and stabilizing effect of the swing arm mechanism 40, the driven link 33 is driven by the active link 32 to reciprocate along the first direction F1. The massage head installed on the driven link 33 follows the driven link 33 to reciprocate along the first direction F1, realizing the massage action.

[0032] The technical solution of the massager in this embodiment includes a housing 10, and a power mechanism 20, a linkage mechanism 30, at least one swing arm mechanism 40, and a main control board 60 disposed within the housing 10. The linkage mechanism 30 includes a linkage seat 31, an active linkage 32, and a driven linkage 33 rotatably connected in sequence. The linkage seat 31 is connected to the power mechanism 20 and is used to drive the linkage seat 31 to rotate about a rotation axis parallel to the second direction F2. The driven linkage 33 is used to connect the massage head. The swing arm mechanism 40 includes at least two swing arms 41 rotatably connected in sequence. The first end 401 of the swing arm mechanism 40 is rotatably connected to the housing 10, and the last end 402 of the swing arm mechanism 40 is rotatably connected to the driven linkage 33. The axes of the rotation nodes at both ends of the active linkage 32 are parallel to the second direction F2, and the axes of each rotation node of the swing arm mechanism 40 are parallel to the second direction F2. In the three directions F3; thus, when the power mechanism 20 drives the connecting rod seat 31 to rotate, the connecting rod seat 31 drives the active connecting rod 32 to swing, so that the active connecting rod 32 generates a driving force on the driven connecting rod 33. Under the motion limiting and stabilizing effect of the swing rod mechanism 40 on the driven connecting rod 33, the driven connecting rod 33 is guaranteed to reciprocate stably along the first direction F1. Compared with the prior art, the technical solution of this embodiment eliminates the need for a bushing to guide the driven connecting rod 33 in the massager, avoiding the problems of high noise, poor motion stability, short service life and short stroke caused by the use of bushings. In addition, each node of the swing rod mechanism 40 is a rotating connection with low motion resistance, making the reciprocating motion of the driven connecting rod 33 smoother and longer in service life. Therefore, the service life of the massager and the stroke of the massage head are effectively improved.

[0033] In some embodiments, the rotation axis of the connecting rod seat 31 and the axis of rotation of the second end 322 of the active connecting rod 32 can be located in the same plane, and designed to be parallel to the first direction F1; that is, the rotation axis of the connecting rod seat 31 and the axis of rotation of the second end 322 of the active connecting rod 32 are distributed in a sequentially opposite manner along the first direction F1, one in front and the other in the rear. With this design, when the power mechanism 20 drives the connecting rod seat 31 to rotate, the distance of the first end 321 of the active connecting rod 32 from the first direction F1 is minimized, and the driving force generated by the second end 322 of the active connecting rod 32 on the driven connecting rod 33 has a larger component in the first direction F1, that is, the effective driving force of the active connecting rod 32 on the reciprocating motion of the driven connecting rod 33 is increased. At the same time, the driving force generated by the second end 322 of the active connecting rod 32 on the driven connecting rod 33 has a smaller component in the third direction F3, reducing the squeezing force of the driven connecting rod 33 on the rocker mechanism 40, thus improving the smoothness and stability of the movement of the driven connecting rod 33. In addition, it can make the design of the linkage mechanism 30 more concentrated in the third direction F3, and the space requirement for the third direction F3 will be smaller, which is more conducive to the compact design of the housing 10.

[0034] Of course, in some other embodiments, the rotation axis of the connecting rod seat 31 and the rotation node of the second end 322 of the active connecting rod 32 are located in the same plane, or they are at a certain angle to the X-axis (such as the range of 0° to 45° or the range of 0° to 60°).

[0035] Reference Figure 5 , Figure 6a and Figure 6b In some embodiments, the rotation node of the second end 322 of the active link 32 is located directly behind the driven link 33 in the first direction F1 (relative to the end of the driven link 33 furthest from the link seat 31 as the front end). Thus, the force exerted by the second end 322 of the active link 32 on the driven link 33 is directly behind the driven link 33, resulting in a smaller lever arm. This reduces the force required for the active link 32 to drive the driven link 33 in reciprocating motion, and consequently, the torque required for the power mechanism 20 to drive the link seat 31 to rotate is also smaller, effectively reducing the power requirement of the power mechanism 20 and thus reducing the power of the massager. In other embodiments, the rotation node of the second end 322 of the active link 32 can also be located to the side or rear of the driven link 33 (e.g., above, below, to the left, or to the right).

[0036] Reference Figure 5 In some embodiments, the swing arm mechanism 40 and the active connecting rod 32 can be arranged in a roughly parallel configuration, with the first end 401 of the swing arm mechanism 40 close to the first end 321 of the active connecting rod 32, and the tail end 402 of the swing arm mechanism 40 close to the second end 322 of the active connecting rod 32. This makes the structure of the swing arm mechanism 40 and the connecting rod mechanism 30 more concentrated, the structure within the housing 10 more compact, and the space requirement within the housing 10 smaller. This helps to reduce the overall size of the massager, making the massager more compact and aesthetically pleasing. Of course, since there are no restrictions on the position of the swing arm mechanism 40's rotatable connection to the housing 10, the swing arm mechanism 40 can be located in various positions relative to its tail end 402, such as directly behind, directly in front, directly above, directly below, or diagonally behind. Therefore, in other embodiments, the swing arm mechanism 40 can also be arranged in other ways.

[0037] In some embodiments, the massager may employ a single swing arm mechanism 40, comprising only two rotatably connected swing arms 41. Using only one swing arm mechanism 40 offers the following advantages: it reduces the size of the mechanism, occupies less internal space, and facilitates a compact design; it also lowers the cost of the mechanism, reducing the overall cost of the massager. Furthermore, having only two swing arms 41 in the mechanism offers the following advantages: the number of swing arms 41 between the tail end 402 and the head end 401 is minimized, resulting in the shortest lever arm. The tail end 402 can withstand a larger component of the third-direction force F3 exerted by the second end 322 of the active connecting rod 32 without deformation along the third-direction F3, meaning the swing arm mechanism 40 has the highest resistance to deformation and is more stable and reliable. Simultaneously, the reduced number of swing arms 41 further lowers the cost of the mechanism, further reducing the overall cost of the massager. Therefore, the solution in this embodiment can achieve the limiting and stabilizing effect on the driven link 33 with the most streamlined swing arm mechanism 40, effectively reducing the cost of the massager and making it more conducive to the miniaturization design of the massager.

[0038] Reference Figure 12 In some embodiments, the massager may also employ two swing arm mechanisms 40, symmetrically arranged on both sides of the driven link 33. This allows the two swing arm mechanisms 40 to limit and stabilize both sides of the driven link 33, better ensuring the stability of the reciprocating motion of the driven link 33. Of course, in other embodiments, the massager may also employ two asymmetrically arranged swing arm mechanisms 40, or even a greater number (e.g., 3 or 4) of swing arm mechanisms 40.

[0039] Reference Figure 3 , Figures 6a to 6c and Figure 10 In some embodiments, the driven link 33 has a connecting platform 332 extending toward the connecting platform 31 at one end near the connecting rod seat 31. The second end 322 of the driving link 32 is rotatably connected to the connecting platform 332 to achieve a rotatable connection between the second end 322 of the driving link 32 and the driven link 33. The connecting platform 332 may extend from the bottom of the driven link 33 near the connecting platform 31, leaving sufficient space above the connecting platform 332 directly behind the driven link 33 to accommodate the second end 322 of the driving link 32. This allows the second end 322 of the driving link 32 to be located directly behind the driven link 33, enabling better driving of the driven link 33. Furthermore, the second end 322 of the driving link 32 shares the Y-axis space occupied by the driven link 33, reducing the Y-axis space requirement in the area where the driven link 33 is located, making the structure within the assembly cavity 101 more compact.

[0040] Continue to refer to Figures 6a to 6c In some embodiments, a step portion 333 is provided on the side of the driven link 33 opposite to the tail end 402 of the rocker arm mechanism 40. The tail end 402 of the rocker arm mechanism 40 is located on the step portion 333 and is rotatably connected to the driven link 33. By providing the step portion 333 on the driven link 33, it is convenient for the driven link 33 to be rotatably connected to the tail end 402 of the rocker arm mechanism 40. The step portion 333 can be formed by a protrusion or a recess in the driven link 33.

[0041] The overall shape of the driven link 33 can be columnar (such as cylindrical, square, etc.) or rod-shaped. In this embodiment, the driven link 33 is generally columnar along the first direction F1 as an example.

[0042] Combined with reference Figure 2 , Figure 3 , Figure 5 , Figures 6a to 7 In some embodiments, the first end 321 of the active link 32 and the link seat 31, and the second end 322 of the active link 32 and the driven link 33 are rotatably connected by a first bearing structure; that is, each rotation node of the linkage mechanism 30 is rotatably connected by a first bearing structure (with low rotational resistance), which makes the rotational resistance of each rotation node of the linkage mechanism 30 smaller, the rotation smoother, and there is almost no wear at the rotation nodes at both ends of the active link 32, which greatly extends the service life of the linkage mechanism 30. In some embodiments, the rocker arms 41 of the rocker arm mechanism 40, the head end 401 of the rocker arm mechanism 40 and the housing 10, and the tail end 402 of the rocker arm mechanism 40 and the driven connecting rod 33 are all rotatably connected by a second bearing structure; that is, each rotation node of the rocker arm mechanism 40 is rotatably connected by a second bearing structure (with low rotational resistance), which makes the rotational resistance of each rotation node of the rocker arm mechanism 40 lower, the rotation smoother, and there is almost no wear at each rotation node of the rocker arm mechanism 40, which greatly extends the service life of the rocker arm mechanism 40. With each rotating node of the linkage mechanism 30 and each rotating node of the swing arm mechanism 40 using a bearing structure for rotational connection, the movement of the linkage mechanism 30 and the swing arm mechanism 40 is smoother, and their service life is significantly improved. This improves the smoothness and service life of the power mechanism 20, resulting in a significant improvement in the smoothness of the massager's operation and its service life. Furthermore, since each rotating node of the linkage mechanism 30 and the swing arm mechanism 40 uses a bearing structure for rotational connection, even if the stroke of the driven linkage (i.e., the maximum stroke of the reciprocating motion along the first direction F1) is significantly increased, there is almost no impact on the wear and tear of each rotating node, allowing the massager to achieve a larger stroke massage operation of the massage head.

[0043] Reference Figure 7The first bearing structure includes a first bearing Z11, a first bearing post Z12, and a first bearing hole Z13 along the second direction F2. The first bearing Z11 is disposed in the first bearing hole Z13, and the outer ring of the first bearing Z11 is fixed to the first bearing hole Z13. The first bearing post Z12 is inserted into the inner ring of the first bearing Z11 and is fixed to the inner ring of the first bearing Z11.

Of course, in other embodiments, the positions of the first bearing post Z12 and the first bearing hole Z13 on the two rotatably connected parts can be interchanged. For example, a first bearing hole Z13 is provided on the first end 321 of the active connecting rod 32, a first bearing post Z12 is provided on the connecting rod seat 31, a first bearing post Z12 is provided on the second end 322 of the active connecting rod 32, and a first bearing hole Z13 is provided on the driven connecting rod 33.

The second bearing post Z22 is inserted into the inner ring of the second bearing Z21 and is fixed to the inner ring of the second bearing Z21. The second bearing post Z22 and the second bearing hole Z23 of the second bearing structure are respectively disposed at two locations rotatably connected by the second bearing structure.

Of course, in other embodiments, the positions of the second bearing post Z22 and the second bearing hole Z23 on the two rotatably connected parts can be interchanged. For example, a second bearing hole Z23 is provided on the first end 401 of the rocker arm mechanism 40, a second bearing post Z22 is provided on the bracket 50, a second bearing hole Z23 is provided on the tail end 402 of the rocker arm mechanism 40, and a second bearing post Z22 is provided on the driven link 33.

[0045] Reference Figure 8 , Figure 8 The diagram shown is a cross-sectional view of one embodiment in which the first component 310 and the second component 320 are rotatably connected by a bearing structure; the two parts rotatably connected by the first bearing structure and / or the two parts rotatably connected by the second bearing structure can all adopt... Figure 8The embodiment shown is as follows. In this embodiment, the bearing post 330 includes a large end 3301, a smooth section 3302 near the large end 3301, and a threaded section 3303 away from the large end 3301. A first component 310 has a locking screw hole 311 that engages with the threaded section 3303. A second component 320 has a bearing hole, and a bearing 340 is disposed in the bearing hole. The outer ring of the bearing 340 is fixed to the bearing hole. The bearing post 330 is inserted into the inner ring of the bearing 340. The smooth section 3302 fits against the inner ring, and the threaded section 3303 extends out of the inner ring of the bearing 340 and is threadedly connected to the locking screw hole 311 on the first component 310, so that the large end 3301 of the bearing post 330 presses against the end of the inner ring of the bearing 340. Furthermore, in this embodiment, an annular flange 3201 is provided on the inner wall of the bearing hole of the second component 320 near the locking screw hole. The outer ring of the bearing 340 abuts against the annular flange 3201 under the locking action of the bearing post 330. An annular boss 312 is provided on the periphery of the locking screw hole 311 of the first component 310. The annular boss 312 abuts against the inner ring of the bearing 340 near the locking screw hole 311. The inner ring of the bearing 340 is clamped between the annular boss 312 and the large end 3301 of the bearing post 330. This makes the rotational connection between the first component 310 and the second component 320 more stable and reliable. The first component 310 and the second component 320 can be either the two parts rotatably connected by the first bearing structure or the two parts rotatably connected by the second bearing structure.

[0046] It should be noted that in other embodiments, the rotational connection of each rotation node of the linkage mechanism 30 and the rotational connection of each rotation node of the rocker arm mechanism 40 can also be achieved by other commonly used rotational connection methods; for example, the two parts of the rotational connection are respectively provided with a shaft and a shaft hole, and the shaft is rotatably inserted into the shaft hole.

[0047] Reference Figure 3 , Figures 6a to 7In some embodiments, the power mechanism 20 includes a motor 21, which is fixed inside the main housing 11. The output shaft 211 of the motor 21 is arranged along the second direction F2, and the output shaft 211 of the motor 21 directly or indirectly drives the connecting rod seat 31 to rotate. In this embodiment, the connecting rod seat 31 is fixed to the output shaft 211 of the motor 21, and the output shaft 211 directly drives the connecting rod seat 31 to rotate, as an example. In this embodiment, the power mechanism 20 drives the connecting rod seat 31 to rotate in the following way: the motor 21 of the power mechanism 20 is directly and fixedly connected to the connecting rod seat 31 through its output shaft 211, so that the connecting rod seat 31 rotates synchronously with the output shaft 211. In this embodiment, the power mechanism 20 uses a motor 21 to drive the connecting rod seat 31 directly. This eliminates the need for mechanical transmission components, simplifies the structural design, and reduces the size and space occupied. At the same time, it avoids problems such as backlash, hysteresis, and elasticity caused by mechanical transmission, resulting in higher precision and reliability. It also reduces energy loss, noise, and vibration caused by mechanical transmission, improves energy efficiency, and provides better quiet operation.

[0048] The fixed connection between the connecting rod seat 31 and the output shaft 211 of the motor 21 can be achieved by: one side of the outer peripheral wall of the output shaft 211 having a positioning plane; the connecting rod seat 31 having a shaft hole adapted to the output shaft 211, into which the output shaft 211 is inserted; and one side of the connecting rod seat 31 having at least one screw hole perpendicular to and communicating with the shaft hole, into which a locking screw is fitted, the end of which presses against the positioning plane of the output shaft 211, thereby achieving a fixed connection between the output shaft 211 and the connecting rod seat 31. Alternatively, the fixed connection between the connecting rod seat 31 and the output shaft 211 of the motor 21 can also be achieved in other ways, such as clamping the connecting rod seat 31 onto the output shaft 211 of the motor 21, or bonding or welding the connecting rod seat 31 to the output shaft 211 of the motor 21, etc. The shape of the connecting rod seat 31 can be rod-shaped, block-shaped, column-shaped, etc.; in this embodiment, a long strip block shape is used as an example.

[0049] Of course, in other embodiments, the output shaft 211 of the motor 21 can also indirectly drive the connecting rod seat 31 to rotate, such as the output shaft 211 of the motor 21 being connected to the connecting rod seat 31 through mechanical transmission components (such as gearbox, synchronous belt, pulley or lead screw).

[0050] In some embodiments, the first end 321 of the active link 32 is rotatably connected to the side of the link seat 31 away from the motor 21. In this way, when the first end 322 of the active link 32 swings around the rotation axis of the link seat 31 (which is also the output shaft 211 of the motor 21), the output shaft 211 of the motor 21 will not interfere with the active link 32, so that the first end 321 of the active link 32 can swing a full circle.

[0051] In some embodiments, a bracket 50 is fixedly provided inside the main housing 11. The bracket 50 and the main housing 11 can be two separate parts, and the bracket 50 is fixedly connected to the main housing 11 by a fixing structure (such as a snap-fit ​​structure, screws, etc.). Alternatively, the bracket 50 and the main housing 11 can be an integral structure, that is, the bracket 50 is part of the main housing 11 itself. In this case, the first end 401 of the swing arm mechanism 40 is directly rotatably connected to the housing 10. In the figures of this embodiment, the bracket 50 and the main housing 11 are two separate parts and are fixed by screws as an example. The structural form of the bracket 50 is not particularly limited and can be designed according to actual needs. In the figures of this embodiment, the bracket 50 is generally plate-shaped as an example. In the figures of this embodiment, the motor 21 is fixed to one side of the bracket 50, and the connecting rod seat 31 is located on the other side of the bracket 50 as an example. The output shaft 211 of the motor 21 passes through the bracket 50 and is fixedly connected to the connecting rod seat 31. Of course, in some other embodiments, the motor 21 may also be located on the same side of the bracket 50 as the connecting rod seat 31, so the output shaft 211 of the motor 21 does not need to pass through the bracket 50.

[0052] In this embodiment, there are many ways to fix the motor 21 to the bracket 50. For example, the motor 21 can be locked onto the bracket 50 with multiple screws, or the bracket 50 can be provided with a structure and buckle that are compatible with the motor 21. The motor 21 can be fastened and fixed onto the bracket 50 by the buckle, or the motor 21 can be directly glued and fixed onto the bracket 50, etc.

[0053] Reference Figure 2 , Figure 3 , Figures 6a to 7 In some embodiments, a base 51 is provided on the bracket 50, and the first end 401 of the swing arm mechanism 40 is rotatably connected to the base 51. The bracket 50 facilitates the rotatable connection with the first end 401 of the swing arm mechanism 40 by providing the base 51. The base 51 can be part of the bracket 50 or an additional structural component mounted and fixed to the bracket 50. In this embodiment, taking the base 51 and motor 21 located on the same side of the bracket 50, and the base 51 and connecting rod seat 31 located on different sides of the bracket 50 as an example, this ensures that the position of the first end 401 of the swing arm mechanism 40 does not interfere with the rotation of the connecting rod seat 31 and the swing of the first end 321 of the active connecting rod 32, allowing for a more compact overall structure within the housing 10.

[0054] The shape of the active linkage 32 is not specifically limited and can be designed according to the space and structure within the massager's housing 10. For example, the active linkage 32 can be a straight strip (see reference). Figure 6c It can also be multi-segmented and bent (see reference). Figure 3 , Figure 5 , Figure 6a or Figure 9). refer to Figure 9 When the active link 32 is a multi-segment bent structure, reinforcing ribs 323 can be set at the bends to enhance the rigidity of each bend of the active link 32 and prevent deformation caused by material elasticity at the bends, thereby ensuring the stable transmission effect of the active link 32.

[0055] like Figure 11 As shown, in some embodiments, the housing 10 may be T-shaped overall (see reference). Figure 11 The casing 10 can also be cross-shaped (see reference). Figure 1 The main shell 11 and the handle 12 are connected to form a T-shaped or cross-shaped structure. Specifically, the handle 12 can extend perpendicularly to the first direction F1, that is, the handle 12 and the main shell 11 are perpendicular to each other; of course, the extension direction of the handle 12 can also have a small angle with the first direction F1 (e.g., 10°, 15°, 20°). In this embodiment, the massager shell 10 adopts an overall shape that is roughly T-shaped or cross-shaped, making the overall shape of the massager more aesthetically pleasing and easier for the user to hold and use. Of course, in other embodiments, the shell 10 can also have other shapes.

[0056] Reference Figure 4 In some embodiments, a control button 103 is installed at the other end of the main housing 11 (i.e., the end away from the opening 102). The main control board 60 is located inside the main housing 11 and close to the control button 103. The main control board 60 has a trigger key 61 corresponding to the position of the control button 103, and the trigger key 61 abuts against the control button 103. The number of control buttons 103 can be one or more. In this embodiment, only one control button 103 is used as an example. By using only one control button 103, the appearance of the massager is made simpler and more aesthetically pleasing. When using the massager, the user presses the control button 103 to trigger the trigger key 61 on the main control board 60, thereby adjusting and controlling the massager, such as controlling the start and stop of the massager and adjusting the massage level. Furthermore, the handheld part 12 is positioned at the other end near the main shell part 11, so that when the user holds the handheld part 12 with one hand, the thumb of the hand holding the handheld part 12 can press the control button 103, thus enabling one-handed operation of the massager, making it more convenient to use.

[0057] Reference Figure 4In some embodiments, a power supply component 70 is installed within the handheld unit 12. The power supply component 70 is electrically connected to the main control board 60 to supply power to the main control board 60 and the power mechanism 20. The power supply component 70 may include a rechargeable battery (such as a lithium battery) and / or a dry cell battery. Additionally, the handheld unit 12 may be equipped with a charging interface (USB port or Type-C port, etc.) to charge the power supply component 70. The handheld unit 12 may also be equipped with a power switch to control the power supply of the power supply component 70 on and off.

[0058] In some embodiments, one end of the main housing 11 is a gradient section 111, and an opening 102 is provided at the end of the gradient section 111. The outer diameter of the gradient section 111 gradually increases from the opening 102 toward the other end of the main housing 11. Thus, the end of the housing 10 where the massage head is mounted is approximately tapered, and the overall shape curve is smoother and more aesthetically pleasing.

[0059] Reference Figure 1 and Figure 4 In some embodiments, an anti-slip sleeve 122 is provided on the outer side of the handheld part 12. The anti-slip sleeve 122 wraps around the outer side of the handheld part 12, making the user's grip more stable. The anti-slip sleeve 122 can be made of a material that improves the grip feel (such as rubber). Specifically, the outer wall of the handheld part 12 can be provided with a groove that matches the shape and size of the anti-slip sleeve 122. The anti-slip sleeve 122 is accommodated in the groove, which can prevent the anti-slip sleeve 122 from moving on the handheld part 12.
