Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a rocker arm type vibration generating device and a vibration massage device. Background Technology

[0002] With the widespread use of massage devices such as fascia guns and massagers, vibration massage has become their most common functional mode. Currently, most of these products use a rotary motor to drive an eccentric counterweight to generate vibration. To increase the vibration intensity, it is usually necessary to increase the motor power or increase the weight and eccentricity of the counterweight; essentially, this relies on increasing centrifugal force to achieve a stronger vibration effect. However, the high-frequency, low-amplitude vibrations generated by this method, when applied to the human body, can easily cause numbness and decreased local sensitivity in the massaged area within a short period of time (approximately 1 minute, varying slightly depending on the location).

[0003] During a massage, the target area must be stimulated to reach its excitation threshold in order to achieve effective relaxation or relief. If local sensory perception weakens, it becomes more difficult to reach the excitation threshold, reducing the actual effectiveness of the massage and the user experience. Therefore, existing vibration generation methods have significant limitations in terms of ergonomics, and the market needs a new type of vibration device that can balance stimulation intensity and sensory adaptability. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rocker arm type vibration generator, which includes a drive motor and comprises... A rocker arm assembly having a passive part, an active part, and a rocker arm joint; A linkage component with a driving end and a response end; A support assembly having a first end and a second end; The drive motor is connected to the drive end; The passive unit is connected to the response terminal; The first end is connected to the rocker arm joint and is used to support and form the fulcrum of the rocker arm assembly; Wherein, the axis from the second end to the middle of the first end is axis L1, and the axis from the rocker arm joint to the middle of the active part is axis L2; The axes L1 and L2 are not parallel; The linkage component is used to link the rotational motion of the drive end into the swaying and / or rotational motion of the axis L2 relative to the axis L1. Wherein, the first end is connected to the first vibration load, and / or, The second end is connected to the second vibration load, and / or, The active part is connected to the third vibration load; The first end, the second end, and the active part are used to transmit vibrational energy to the outside.

[0005] Furthermore, the third vibration load is a counterweight.

[0006] Furthermore, the active part performs circular motion around axis L1.

[0007] Furthermore, the axis L2 moves in a swinging motion with the rocker arm joint as the center.

[0008] Furthermore, the active part performs elliptical motion around axis L1.

[0009] Furthermore, the first end is provided with a first sliding groove, the sliding direction is perpendicular to the axis L1, and a first slider is installed in the first sliding groove; The rocker arm joint is connected to the first slider, and the first slider forms the fulcrum.

[0010] Furthermore, the first end is provided with a waist-shaped hole, the length direction of which is perpendicular to the axis L1; the rocker arm joint is provided with a first protrusion, and the circumferential wall surface of the first protrusion and the inner wall surface of the waist-shaped hole are provided with mutually coupled spherical surfaces.

[0011] Furthermore, the active part has a protective sleeve; The sheath is fitted over the outside of the active part to isolate the active part from the flexible layer of the massager. Furthermore, the sheath can rotate freely relative to the active part.

[0012] Furthermore, the support component is fixedly connected to the drive motor.

[0013] Furthermore, the drive motor is flexibly connected to the drive end, and, It is flexibly connected directly or indirectly to the support component.

[0014] Furthermore, the angle between axis L1 and axis L2 is α, and the degree of angle α is 5°-30°.

[0015] Furthermore, a vibration massage device, the massage device comprising, any one of the rocker arm vibration generating devices described above; and including, A cylindrical elastic massage sleeve with an inner cavity; The rocker arm type vibration massage device is disposed inside the inner cavity; The swaying and / or rotational motion of axis L2 relative to axis L1 can cause the cylindrical elastic massage sleeve to undergo periodic bending deformation.

[0016] The beneficial effects of this invention are reflected in the fact that, during the movement of the rocker arm assembly, both the active and passive parts generate centrifugal force, and the ends of both the active and passive parts can vibrate. Since this location does not experience vibration transmission and loss, the amplitude is relatively large. Furthermore, both ends of the fulcrum in this invention vibrate, and the vibrations from both ends converge towards the fulcrum. The energy of the two vibrations is superimposed at the fulcrum, which to some extent compensates for the energy lost when a single vibration energy is transmitted to the fulcrum. This results in a relatively consistent vibration amplitude along the overall length of the vibration generating device, and the vibration amplitude in this area is basically close to the maximum amplitude that the device can generate. Therefore, using the vibration massager of this invention ensures a large-amplitude vibration effect over a large massage area. Attached Figure Description

[0019] 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.

[0020] Example 1 Reference Figure 1 - Figure 20 .

[0021] A rocker arm type vibration generator, comprising a drive motor 1, including, A rocker arm assembly 2 having a passive part 21, an active part 22 and a rocker arm joint 23; A linkage component 3 having a driving end 31 and a response end 32; A support assembly 4 having a first end 41 and a second end 42; The drive motor 1 is connected to the drive end 31; The passive unit 21 is connected to the response terminal 32; The first end 41 is connected to the rocker arm joint 23 and is used to support and form the fulcrum of the rocker arm assembly 2. Wherein, the axis from the second end 42 to the first end 41 is L1, and the axis from the rocker arm joint 23 to the active part 22 is L2; The axes L1 and L2 are not parallel; The linkage component 3 is used to link the rotational motion of the drive end 31 into the swaying and / or rotational motion of the L2 relative to the L1. The first end 41 is connected to the first vibration load 51; The second end 42 is connected to the second vibration load 52; The active part 22 is connected to the third vibration load 53; The first end 41, the second end 42, and the active part 22 are used to transmit vibration energy to the outside.

[0022] This embodiment provides a rocker arm type vibration generator. It first includes a drive motor 1, which provides the power for rotation.

[0023] It also includes a rocker arm assembly 2 and a support assembly 4.

[0024] The rocker arm assembly 2 includes at least a passive part 21, an active part 22, and a rocker arm joint 23.

[0025] A support assembly 4 having a first end 41 and a second end 42; Regarding the swing motion, the rod that is hinged to the support assembly 4 and swings back and forth can be referred to as the rocker arm assembly 2, see reference. Figure 1 and Figure 2 Alternatively, a rod that is tilted relative to a rotation axis and then rotates around a point on the rotation axis as a fulcrum can be called rocker arm assembly 2, see reference. Figure 6 - Figure 9 .

[0026] The support component 4 is a part that can provide a fulcrum for the rocker arm assembly 2. The support component 4 has at least two connecting parts, namely a first end 41 and a second end 42. The first end 41 is connected to the rocker arm joint 23 to support and form a fulcrum for the rocker arm assembly 2, and is connected to the first vibration load 51. The first vibration load 51 refers to a structure that can generate resistance to the movement of the support component 4. That is, the first vibration load 51 restricts the movement of the first end 41, and the first end 41 restricts the movement of the rocker arm assembly 2, as shown in the reference. Figure 20 As shown, the first vibration load 51 can be a flexible sleeve or a rigid shell surrounding the first end 41 of the support assembly 4. (Refer to...) Figure 20 As shown, the second end 42 is connected to the second vibration load 52. The support component 4 has a certain length and can be understood as a cylindrical structure. The two ends of the cylindrical structure are the first end 41 and the second end 42, respectively. A hole is provided at the first end 41, which connects to the rocker arm joint 23 and provides a fulcrum for the rocker arm component 2. Then, the flexible sleeve can directly wrap around the outer circular wall of the cylindrical structure. That is, the first end 41 is connected to the first vibration load 51, and the second end 42 is connected to the second vibration load 52.

[0027] Wherein, the axis from the second end 42 to the first end 41 is L1, and the axis from the rocker arm joint 23 to the active part 22 is L2; Axis L1 is an axis formed by the support assembly 4. The support assembly 4 can be a bracket or sleeve of various shapes. Axis L1 is formed between the position connecting the rocker arm joint 23 and the position connecting the second vibration load 52 in the support assembly 4. That is, axis L1 is formed between the first end 41 and the second end 42. Axis L2 is the axis extending from rocker arm joint 23 in rocker arm assembly 2 to the active part 22. The extension direction of passive part 21 and rocker arm joint 23 does not require special requirements. Passive part 21 can swing or rotate relative to axis L1 through the cooperation between linkage assembly 3 and drive motor 1.

[0028] Among them, reference Figure 1-3 As shown, oscillation refers to the fact that when axis L2 oscillates, the fulcrum position forms a rotation axis that is perpendicular to axis L1 and passes through axis L1, and axis L2 oscillates back and forth on the left and right sides of axis L1 around the rotation axis.

[0029] Among them, reference Figure 4-10 As shown, rotation means that axis L2 and axis L1 are not parallel, but intersect. When axis L2 rotates, the intersection of axis L2 and axis L1 forms the rotation vertex, which is the position where the first end 41 and rocker arm joint 23 are connected. The movement path of axis L2 will form a cone shape.

[0030] In this application, the passive part 21 in the rocker arm assembly 2 refers to the part that connects to the drive motor 1, and the passive end is responsible for receiving the power of the drive motor 1 to rotate.

[0031] If the rocker arm assembly 2 performs the aforementioned swinging motion, then the drive motor 1 will drive the passive part 21 to reciprocate around the rotation axis in an arc path; if the rocker arm assembly 2 performs the aforementioned rotating motion, then the drive motor 1 will drive the passive part 21 to rotate around the motor axis in a circular motion. This circular rotational motion can be further improved into an elliptical rotational motion.

[0032] Furthermore, the rocker arm assembly 2 has three motion modes: horizontal swing, circular rotation, and elliptical rotation. The transmission structure (passive part 21 and linkage assembly 3) and connection structure (first end 41 and rocker arm joint 23) of the rocker arm assembly 2 are different in the three motion modes.

[0033] I. Forms of Swaying Motion The vibrations generated by the reciprocating rocking motion are mainly concentrated on both sides perpendicular to the swing axis, while the vibration amplitude at the ends of the swing axis is smaller. Therefore, the circumferential vibration effect of the rocker arm vibration generator is not uniform. This is suitable for massage applications requiring concentrated vibration, specifically targeting specific massage points. The corresponding structure is as follows: 1.Reference Figure 2 , Figure 3 As shown, the first end 41 is provided with a shaft, and the rocker arm joint 23 is provided with a hole; or the first end 41 is provided with a hole, and the rocker arm joint 23 protrudes with a shaft, and the two can be hinged together, with the hinge axis perpendicular to the axis L1.

[0034] II. Rotational Motion Forms The vibration generated by the circular rotation motion spreads around the axis of the drive motor 1, resulting in a uniform vibration effect throughout the circumference of the entire rocker arm vibration generator. This is suitable for cylindrical massagers inserted into the body for massage, providing a uniform massage effect to the areas around the massager. Furthermore, the directionality of the massager is not a concern; the user can rotate the massager to allow the external massage textures to create a rotating massage effect on the target area without affecting the vibration massage effect. In the rocking motion, the active part 22 cannot participate in vibration output during its swing back towards L1, and the drive motor 1 needs to actively overcome inertia to swing the active part 22 back to the other side. However, in the circular rotation motion, the active part 22 always maintains the same distance from the axis L, and the direction of motion does not change during the rotation. The drive motor 1 does not need to counteract the inertia of the active part 22. Therefore, the rocker arm vibration generator with the rotation motion is easier to achieve a vibration effect with a smaller drive motor 1. The corresponding structure is as follows: First, refer to Figure 5 and Figure 6 The first end 41 is provided with a hole, the wall of which is spherical, and the center of the hole is located in L1. The rocker arm joint 23 forms a protrusion along the radial direction of the rocker arm assembly 2, and the circumferential wall of the protrusion is spherical, forming a spherical fit between the two. When the spherical wall of the hole is a convex spherical surface, the circumferential wall of the protrusion is a concave annular spherical surface; when the spherical wall of the hole is a concave spherical surface, the circumferential wall of the protrusion is a convex spherical surface. Under this fit, the rocker arm assembly 2 uses the center of the sphere as the center of rotation, and the points where the wall of the spherical hole participates in support are all fulcrums.

[0035] Secondly, refer to Figure 7 The first end 41 can be provided with a flexible cover plate (such as rubber, silicone, etc.) and has holes. The main body of the support component 4 is cylindrical. The flexible cover plate is connected to the front end of the support component 4. The rocker arm component 2 passes through the hole of the flexible cover plate. At this time, the rocker arm component 2 and the edge of the hole it passes through when passing through the flexible cover plate are the fulcrum. During the swinging process of the rocker arm component 2, the flexible cover plate is squeezed and deformed, and the fulcrum will change, so as to avoid the swinging of the rocker arm component 2. The rocker arm joint 23 can be directly bonded to the flexible cover plate, or it can protrude in the radial direction of the rocker arm component 2 to form two axial limiting parts. The flexible cover plate is located between the two axial limiting parts, and the axial limiting parts prevent the rocker arm joint 23 and the flexible cover plate from sliding.

[0036] Thirdly, refer to Figure 8 The first end 41 is set as a thin plate that is not easily deformed. A hole is made in the thin plate, and the axis of the hole is coaxial with the drive motor 1. The hole is made in the thin plate and the depth of the hole is very short. For a hole with a certain depth, both ends of the hole will support the rod, so that the two points determine a straight line, which prevents the rod from swinging. However, the two ends of the hole with a very short depth are very close, so the original two support points are combined into one. The straight line can rotate freely 360 degrees through a single point. Since the short hole cannot restrict the swing freedom of the rod, the rocker arm assembly 2 can still swing freely in the short hole of the first end 41. At the same time, the rocker arm assembly 2 is provided with at least two protrusions around its circumference. The two protrusions are spaced apart along the axis L1. The groove between the two protrusions forms the rocker arm joint 23, which is coupled to the aforementioned short hole. The greater the distance between the two protrusions, the greater the range of motion of the rocker arm.

[0037] Fourth, refer to Figure 9The first end 41 still has a hole, which is coaxial with the drive motor 1. A groove is formed on the inner circumferential wall of the hole, and a boss protrudes radially at the rocker joint position, with the boss located inside the groove. It should be noted that the thickness of the boss is less than the thickness of the groove, and the diameter of the hole is greater than the diameter of the rocker joint 23 (the rocker joint 23 is not necessarily cylindrical; here, the diameter refers to the diameter of the circumcircle formed by the edge of the rocker joint 23) to ensure that the boss has a certain amount of tilting space.

[0038] Fifth, refer to Figure 10 The support component 4 remains a cylindrical structure, with the first end 41 being one end of the cylindrical structure. Several flexible strips connect the outer circular wall of the rocker arm assembly 2 to the inner circular wall of the cylindrical structure. The connection points are located at the first end 41 and the rocker arm joint 23 (at this point, the first end 41 and the rocker arm joint 23 do not require additional structures, only specific locations). For example, four rubber strips are arranged in a cross shape. One end of each rubber strip connects to the inner wall of the support component 4, and the other end connects to the rocker arm joint 23. When the rocker arm assembly 2 swings towards one of the rubber strips, the point where the rubber strip on the opposite side connects to the rocker arm joint 23 serves as the fulcrum for the rocker arm assembly 2's swing. The front and rear ends of the rocker arm assembly 2 swing in opposite directions.

[0039] III. Elliptical Rotational Motion The vibration generated by the elliptical rotational motion is actually a combination of the reciprocating oscillation and rotational motions mentioned above. That is, the vibration effect along the major axis of the elliptical trajectory is greater than that of the rotational motion, while the vibration effect along the minor axis is greater than that on both sides of the oscillating axis in the swinging motion. The vibration of the rotational motion is non-directional, propagating evenly in all directions. Although the area to be massaged can be enveloped by the massager, different locations on the inner wall of the area to be massaged have different levels of sensitivity. There are sensitive points at the top and bottom of the channel within the area to be massaged. Therefore, the vibrational energy can be mainly concentrated at the upper top and lower bottom of the channel, i.e., the major axis of the elliptical trajectory points towards the top and bottom. The minor axis of the elliptical trajectory points towards the left and right sides of the channel, ensuring sufficient vibration on both sides of the area to be massaged.

[0040] Structurally, the elliptical rotational motion form is actually a further improvement on the circular rotational form. The corresponding structure is: First, refer to Figure 11 and Figure 12The first end 41 is provided with a first groove 411, and a first slider 412 is installed in the first groove 411. The sliding direction is perpendicular to the axis L1. Then, a spherical hole is provided in the first slider 412. The rocker arm joint 23 is a spherical protrusion. The rocker arm joint 23 is nested in the spherical hole to realize the rotation action. The first slider 412 drives the rocker arm joint 23 to slide along the first groove 11. Therefore, the original circular trajectory will be elongated to form an ellipse.

[0041] Secondly, refer to Figure 13 and Figure 14 A waist-shaped hole 413 is provided in the first end 41, and then the rocker arm assembly 2 is inserted into the waist-shaped hole 413. The inner wall surface of the waist-shaped hole 413 is spherical, and the rocker arm joint 23 is provided with a first protrusion 231. The circumferential wall surface of the first protrusion 231 is spherical, and the spherical surfaces of the two are coupled to each other. When the spherical surface of the waist-shaped hole 413 is concave, the spherical surface of the rocker arm joint 23 is convex; correspondingly, when the spherical surface of the waist-shaped hole 413 is convex, the spherical surface of the rocker arm joint 23 is concave. The spherical fit provides a center point for the rotation of the rocker arm assembly 2. The waist-shaped hole 413 has a length, and the rocker arm assembly 2 will also slide during rotation, thereby lengthening the circular rotation trajectory and forming an elliptical trajectory.

[0042] Furthermore, the drive motor 1 can only provide rotational force, while the rocker arm assembly 2 has multiple motion forms, making it difficult for the drive motor 1 to directly drive the passive part 21. Therefore, the device in this application also includes a linkage assembly 3, which includes a drive end 31 and a response end 32. The drive end 31 only needs to be able to connect to the output shaft of the drive motor 1; for example, the drive end 31 can have a hole, and the output shaft of the drive motor 1 can be directly inserted into the hole of the drive end 31 for fixation.

[0043] The response end 32 has various structural forms, and the structure of the response end 32 will also be different when the rocker arm assembly 2 performs different motion forms.

[0044] I. Structure corresponding to the swinging motion: 1. A groove is provided in the passive part 21, wherein the two side walls of the groove are respectively located in the reciprocating direction of the swing. The response end 32 rotates around the axis L1 (which can be achieved by the linkage component 3 being connected to the support component 4 by a shifting connection), or the axis of the drive motor 1 is coaxial with the axis L1, and the linkage component 3 is directly fixed in the output shaft of the drive motor 1. The response end 32 is set as an eccentric protrusion, which is eccentric relative to the axis L1. The eccentric protrusion is inserted into the groove of the passive part 21 and abuts against the side wall of the groove. When the eccentric protrusion rotates, the direction of deviation from L1 changes, thereby abutting against and pushing the side wall of the groove, causing the rocker arm assembly 2 to swing.

[0045] II. Structures corresponding to rotational motion: During the rotational movement of the rocker arm assembly 2, the passive part 21 can be a simple rod, one end of which is fixedly connected to the rocker arm joint 23, and the other end serves as a mating end. The mating end mates with the responding end 32, which only needs to be able to push the mating end to rotate around the axis L1. Specifically, for example: First, refer to Figure 5 - Figure 9 The linkage component 3 is a connecting plate. The output shaft of the drive motor 1 is perpendicular to the plate surface of the connecting plate and fixed to the linkage component 3. The edge of the connecting plate is provided with a groove or hole as a response end 32. The mating end of the passive part 21 is inserted into the response end 32. The drive motor 1 drives the entire connecting plate to rotate, and then the wall of the groove or hole pushes the mating end to rotate around the axis L1.

[0046] Secondly, refer to Figure 15 Correspondingly, the mating end of the passive part 21 can also be provided with a groove or hole, and then a protruding rod is provided in the connecting plate as a response end 32. The response end 32 is inserted into the groove or hole of the mating end, which can also achieve the same result: the mating end rotates around the axis L1.

[0047] Thirdly, refer to Figure 16 The response part is set as a V-shaped structure, and the passive part 21 is set as a rod. It is passively inserted into the opening position of the V-shaped structure. The main shaft of the drive motor 1 is connected to the intersection position of the V-shaped structure, which drives the entire V-shaped structure to rotate. The wall of the opening of the V-shaped structure pushes the passive part 21 to rotate.

[0048] Furthermore, Wherein, the first end 41 is connected to the first vibration load 51; and or, The second end 42 is connected to the second vibration load 52; and or, The active part 22 is connected to the third vibration load 53; Vibration is relative. The rotation or swaying of the active part 22 is relative to the support component 4. Therefore, the support component 4 must have a certain resistance. For example, if you pinch the support component 4 directly with your fingers, if there is only one position that generates resistance to the support component 4, the entire vibration generating device will easily swing. Therefore, at least one position is needed to connect the load. This makes the first end 41 and the second end 42 of the support component 4 connected to the first vibration load 51 and the second vibration load 52, respectively. The position of the second end 42 is not special and can be any position in the support component 4. The optimal setting is that the second end 42 is the end of the support component 4 that is farthest from the first end 41. The second vibration load 52 can also be understood as the resistance from the massager housing or silicone sleeve. At the same time, the drive motor 1 can also be fixedly connected in the support component 4, and the weight of the support motor itself generates a load on the second end 42.

[0049] The active part 22 is connected to the third vibration load 53. The active part 22 is the end of the rocker arm assembly 2, which can be connected to a counterweight as the third vibration load 53, or any external component that can block the movement of the third vibration load 53. All movements are relative. A motor drives a shaft to rotate, but if the motor shaft is fixed, the motor will drive the housing to rotate. In this application, the rocker arm assembly 2 can be understood as the shaft of the aforementioned motor. If the active part 22 is fixed, it will support the swinging of the assembly 4. Therefore, the aforementioned first vibration load 51, second vibration load 52, and third vibration load 53 are actually a kind of resistance, preventing the movement of each component. However, the device needs to generate vibration, and the device cannot be completely fixed. Therefore, the method of connecting loads is used to generate resistance to the movement of the device while having a offset movement that does not completely restrict the vibration.

[0050] A comparison is made between a rocker arm vibration generator in the form of circular rotation motion and a vibration motor in the prior art; Existing vibration motors consist of a drive motor 1 and an eccentric counterweight. The eccentric counterweight moves in a circular motion around the output shaft of the drive motor 1. Typically, the housing of the drive motor 1 is fixed. Imagine that in this type of vibration motor, the vibration amplitude is greatest near the eccentric counterweight, and the vibration transmission exhibits a conical structure. After the vibration motor is connected to the massager housing, the vibration amplitude that the massager housing can receive is further reduced. Therefore, massagers using existing vibration motors with the same drive motor 1 are more likely to cause numbness, mainly because the transmitted vibration amplitude is smaller. Furthermore, products using existing vibration motors do not exhibit uniform vibration intensity across the vibration functional areas; the best vibration effect is concentrated near the eccentric counterweight.

[0051] Using the rocker arm vibration generator of this application, a wide-range and uniform vibration effect can be obtained, and the vibration amplitude is superior to that of existing vibration motors, making it less likely for users of the massager to feel numb and expanding the coverage of the vibration massage. Specifically, when the drive device of this application rotates, both ends of the drive device, namely the active part 22 and the passive part 21, will participate in the movement deviating from the axis L1. Taking the line connecting the rocker arm joint 23 to the force point of the passive part 21 as L3, both L2 and L3 are inclined relative to L1. Figure 17As shown, after rotation occurs, L2 and L3 form a double cone shape with the rocker joint 23 as the vertex (in the swing motion form, a double triangle with the rocker joint 23 as the vertex opposite each other). Both the active part 22 and the passive part 21 can be equivalent to the eccentric blocks of a vibration motor in the prior art. The active part 22 and the passive part 21 are located on both sides of the rocker joint 23, which is connected to the first end 41. This causes centrifugal force to be generated at both ends of the rocker joint 23. The fulcrum of the support component 4 supports the rocker joint 23. Originally, the centrifugal force is smaller closer to the fulcrum, and the vibration effect is worse. However, in this application, both ends of the fulcrum generate vibration, and the vibrations at both ends converge towards the fulcrum position. The energy of the two vibrations is superimposed at the fulcrum position, which to some extent compensates for the energy consumed when a single vibration energy is transferred to the fulcrum position. This ensures that the vibration generating device has a relatively consistent vibration amplitude along its overall length, and the vibration amplitude in this area is basically close to the maximum amplitude that the device can emit (the maximum amplitude that the device can emit refers to the amplitude near the active end, which is equivalent to the amplitude at the position of the eccentric counterweight in the prior art). This guarantees that the vibration massager of this application has a large-amplitude vibration effect over a large massage area, ensuring that the massage area completely covers the sensitive points in the massage area; the coverage of the massage area and the maintenance of a large vibration amplitude within this area effectively prevent localized numbness in the massaged area.

[0052] Furthermore, refer to Figure 6 - Figure 8 as well as Figure 17 The angle between axis L1 and axis L2 is α, and the degree of angle α is 5°-30°. The degree of angle α should not be too large. After axis L2 rotates or swings, the angle formed by the two sides of axis L2 in the motion path is twice the degree of angle α. The maximum degree of angle α is 30°. The smaller the degree of angle α, the more vibration energy will converge towards the vertex position, thereby avoiding the vibration energy of the active part 22 being much greater than the vibration energy of the vertex, resulting in uneven vibration amplitude. Figure 17 The shaded area is the region where vibrational energy converges on both sides of the fulcrum.

[0053] Example 2 Reference Figure 2 As shown, the active part 22 has a main body and a sheath 221; The sheath 221 is fitted over the outside of the main body, and the sheath 221 can rotate freely relative to the main body.

[0054] During rotation, the active part 22 rubs against the inner wall of the flexible layer of the massager for an extended period, which can easily cause it to tear. Reducing friction usually involves adding a lubricating medium, but this friction path is a loop, and the relative positions of the active part 22 and the flexible layer are constantly changing, making it difficult for the lubricating medium to remain within the friction path. To address this, in this embodiment, a protective sleeve 221 is added to the active part 22. The sleeve 221 is fitted over the active part 22, with its outer wall directly contacting the flexible layer of the massager, and its inner wall rotatably connected to the active part 22. A bearing can be installed between the sleeve 221 and the active part 22 to make their rotation smoother. The active part 22 indirectly contacts the flexible layer through the sleeve 221, converting the original sliding friction into rolling friction, greatly reducing friction and effectively preventing the active part 22 from tearing the flexible layer. Furthermore, the vibration effect at the indirect contact point between the active part 22 and the flexible layer can still be effectively transmitted to the outside of the massager. When the third vibration load 53 is a counterweight, the sheath 221 also needs to wrap the third vibration load 53. That is to say, the active part 22 is only allowed to contact the flexible layer spacing through the sheath 221.

[0055] Example 3 Reference Figure 1 - Figure 16 As shown.

[0056] The support assembly 4 can be directly and fixedly connected to the drive motor 1. For example, if the support assembly 4 is a cylindrical structure, then the two ends of the support assembly 4 are respectively the first end 41 and the second end 42. The first end 41 is connected to the rocker arm joint 23, and the second end 42 is connected to the drive motor 1. In this case, the weight of the drive motor 1 itself can be directly used as the second vibration load 52.

[0057] Example 4 Reference Figure 18 and Figure 19 .

[0058] Furthermore, the drive motor 1 is flexibly connected to the drive end 31, and, It is flexibly connected directly or indirectly to the support component 4.

[0059] The output shaft of the drive motor 1 can be connected to the drive end 31 via a flexible shaft 11. The flexible shaft 11 needs to have sufficient anti-rotation strength to ensure that the power of the drive motor 1 can be transmitted to the drive end 31. The flexible shaft 11 has low bending resistance.

[0060] In the entire massager, the drive motor 1 must be fixed, but it does not necessarily need to be fixed in the support assembly 4. The drive motor 1 can also be fixed in the massager's housing, and then the drive motor 1 and the drive end 31 are flexibly connected. This means that there can be relative displacement between the drive end 31 and the drive motor 1 (the displacement here mainly refers to the offset generated during vibration). Furthermore, the drive motor 1 does not need to be directly connected to the support assembly 4. For example, the flexible layer of the massager directly wraps around the support assembly 4 and the drive motor 1, and the drive motor 1 is not rigidly connected to the support assembly 4, but is connected through the flexible layer of the massager in this application. Further, refer to... Figure 18 The flexible layer of the massager needs to be in direct contact with the human body, so the material is limited. An overly soft flexible layer may not be able to maintain the basic shape of the massager. An elastic element 43 can be added between the support component 4 and the drive motor 1 to maintain the basic shape of the massager, while not completely restricting the freedom of the support component 4. The support component 4 will not be unable to move because the drive motor 1 is fixed. At this time, the better the rigidity of the part, the better the vibration transmission effect. At this time, the flexible connection structure of the drive motor 1 blocks the transmission of vibration. The position of the drive motor 1 can be almost without vibration. The drive motor 1 is fixedly connected to the shell of the grip part in the massager, so the user's hand will not be affected by vibration and avoid numbness of the hand.

[0061] Meanwhile, the second end 42 of the support component 4 no longer needs to be connected to the drive motor 1. The second end 42 can be directly connected to the flexible layer, using the elasticity of the flexible layer as the second vibration load 52 (the second vibration load 52 also includes the elasticity of the flexible shaft 11 and the elastic element 43). With the power of the drive motor 1 remaining constant, the heavier the load, the more difficult it is to increase the vibration amplitude. The drive motor 1 is the heaviest component in the entire rocker arm vibration drive device. In this embodiment, the vibration motor does not participate in the vibration, greatly reducing the weight of the second vibration load 52, allowing the device of this application to easily increase the vibration amplitude; and as... Figure 19 As shown, the drive motor 1 is connected to the drive end 31 via a flexible shaft 11. The flexible shaft 11 can transmit power in a bent state, thus the drive motor 1 has a more flexible installation position. When the length of the part of the massager that needs to vibrate is insufficient to accommodate the rocker arm vibration drive device together with the drive motor 1, the flexible shaft 11 can be bent, and then the drive motor 1 can be installed on the side of the support assembly 4, so that the rocker arm vibration drive device of this application can be adapted to more types of vibration massagers.

[0062] Example 5 Reference Figure 1-20 As shown.

[0063] This embodiment provides a vibration massage device using the rocker arm vibration drive device of this application.

[0064] Includes a cylindrical elastic massage sleeve 6 with an inner cavity; The rocker arm type vibration massage device is disposed inside the inner cavity; The swaying and / or rotational motion of direction L2 relative to direction L1 can cause the cylindrical elastic massage sleeve 6 to undergo periodic bending deformation.

[0065] In existing vibrating massagers, the vibrating motor is wrapped very tightly because the vibration needs to pass through the flexible layer of the massager to be transmitted to the human body. The better the rigidity of the parts and the tighter the connection with the vibrating motor, the better the vibration is transmitted. Therefore, the flexible layer wrapped around the vibrating motor in existing technology is relatively thick, achieving a kind of toughness and elasticity, and the flexible layer wrapped around the vibrating motor will not deform during massage.

[0066] In this embodiment, the cylindrical elastic massage sleeve 6 has a relatively small elastic coefficient, making it more prone to bending. The vibration energy from the rocker-arm vibration drive device, once activated, can deform the cylindrical elastic massage sleeve 6. The main offset direction of vibration in the rocker-arm vibration drive device is perpendicular to the axis L1, and the amplitude of vibration is greatest in this direction. By installing the rocker-arm vibration drive device in the cavity with the axis L1 parallel to the length of the cylindrical elastic massage sleeve 6, the offset of vibration makes it easier for the cylindrical elastic massage sleeve 6 to undergo periodic bending deformation. Simultaneously, during use, the cylindrical elastic massage sleeve 6 is inserted into the area to be massaged, and the area to be massaged wraps around the circumferential wall of the cylindrical elastic massage sleeve 6. Therefore, the area to be massaged mainly receives vibration in the direction of maximum amplitude, avoiding the numbness caused by small vibrations.
