TECHNICAL AREA
[0001] The present invention belongs to the technical field of massage and health care and relates to percussion massage simulation technology and in particular to a contact mass percussion device and a massage device. BACKGROUND
[0002] Massage aims to achieve health, well-being, and stimulation through direct contact with the body. The commercial market for massage products is growing rapidly. Among the numerous types of massage, percussion massage is one of the most important. The massage effects and stimulation achieved through percussion massage are difficult to replicate with other massage methods.
[0003] Many existing massage products utilize a contact massage mode, all of which can be considered either a tapping massage or an extension of a tapping massage mode. For example, an eccentric vibration motor is mounted on the main body of a massager, and this motor drives an inertial eccentric wheel, causing it to rotate and vibrate a housing within the device's main body. The object being massaged experiences a tapping sensation caused by the impact during vibration. However, the frequency of this type of tapping sensation is generally high, and the amplitude is not large, resulting in insufficient tapping intensity.Especially when a massage device is an in-body massager or one that is placed on the skin, the vibration / tapping sensation is significantly reduced when the device is applied to the skin or internally with a certain amount of force. Furthermore, when a vibrating massager simulates tapping effects, the entire main body (housing) of the device typically vibrates. This vibration generally arises from the reaction force of the vibration, generated by the inertia of a motor and cams within the housing. The housing's vibration creates an undifferentiated tapping stimulation. Currently, there is no solution for targeted tapping stimulation in specific local areas. BRIEF DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE EXECUTION FORMS
[0018] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings. It is obvious that the described embodiments represent only some, and not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art in this field, without any creative effort, based on the embodiments of the present invention, fall within the scope of protection of the present invention.
[0019] With reference to the figures, specific embodiments of the present invention are as follows: Design 1:
[0020] A contact massage percussion device comprising a percussion device housing with a cavity (1) having a first opening (3) wherein the housing comprises: • a knocking body (2) with at least one movable connecting element and a drive end (23); • a connecting seat; • a knock drive arrangement (5); • at least one movable connecting element connects the knocking body (2) to the connecting seat; • the knocking body (2) has at least one degree of freedom A for a back-and-forth movement relative to the connecting seat; • the drive arrangement (5) is connected to the drive end (23) of the knocking body (2) and is configured to provide the force for a reciprocating movement of the knocking body (2) in degree of freedom A; and • the housing of the knocking device is arranged inside the cavity (1).
[0021] In this embodiment, the connecting seat is configured to support the tapping body (2); the tapping body (2) is the main part that performs the tapping massage stimulation function, and its massage characteristics can be configured with various or user-defined settings according to the type of massage and the stimulation site. The tapping body (2) can have a specific inertial orientation; for example, the center of the tapping body (2) can be located as close as possible to the point where the tapping motion takes place, or it can be positioned at other locations according to the massage and tapping requirements to achieve better inertia; in particular, under the action of the drive arrangement, the tapping body (2) exhibits a reciprocating oscillation mode of motion.Given a specific material selection, adjusting the center of gravity within a reasonable range can improve the torque required to drive the tapping body (2) and further improve the natural frequency of the moving tapping body (2), thus optimizing the dynamic process of the tapping motion. Optimized results can improve the energy efficiency of the drive assembly and enhance the tapping motion of the tapping body (2). Regarding the arrangement of the cavity (1), the cavity (1) is configured to protect the freedom of movement of the tapping body (2) from obstructions, including collisions and friction upon contact, as well as from obstructions caused by the escape of a medium (e.g., air) into a small space (or a negative pressure created by the striking device upon exiting the cavity (1)).The obstruction caused by the medium can be overcome by incorporating backflow grooves or holes on an inner wall of the cavity (1) or on side arms of the housing, as well as by other solutions. This embodiment achieves a genuine stimulating effect of the percussion massage, and the cavity (1) provides the percussion body (2) with an inertial energy storage space, so that the energy of the percussion action of the percussion body (2) exhibits both stored and explosive properties, significantly enhancing the stimulation. The structure in which the percussion body (2) is connected via the connecting seat makes the movement of the percussion body (2) relatively independent, so that it is virtually impossible for the percussion effect to be significantly reduced due to poor energy storage of the percussion body (2) caused by the close contact between the massager and the object being massaged (including the body's enveloping surface). Design 2:
[0022] The knocking body (2) has a first knocking surface (21); • wherein the first tapping surface (21) has a first extreme position; and • the first extreme position is the extreme position in which the first knocking surface (21) can protrude from the cavity (1) through the first opening (3) by at least one movement segment of the degree of freedom A.
[0023] In this embodiment, the striking surface can be designed in various shapes or structures depending on the desired massage effects or application areas. Since the striking body (2) performs a reciprocating motion, there is an extreme position during this motion. In this embodiment, the extreme position refers to the position that the first striking surface (21) can reach during general movement (at any speed) of the drive device. In contrast to the extreme position, there is an inertial end position, since in reality no rigid bodies exist (no elastic deformation is observed). This means that the actual position reached by the striking surface depends not only on the movement of the drive module but also on the inertial mass distribution (center of gravity position) and the speed of movement of the striking body (2).This can result in the inertial end position being larger or smaller than the extreme position defined in this embodiment. This embodiment is based on the premise that the tapping element (2) is considered approximately as a rigid body (the intrinsic elasticity of the tapping element (2) is only minimally affected by the inertia of the drive device at normal operating speed and meets the criterion of being significantly smaller / negligible). Based on this premise, the first extreme position is set such that the tapping element (2) protrudes from the cavity (1), in particular from the first opening (3) of the cavity (1).Since the application device is a contact massager, the interaction of the percussion body (2) with the object to be massaged generally occurs at the first opening (3) of the cavity (1) or slightly further forward when the percussion body (2) reaches the first opening (3), as the object to be massaged is generally a physical body that penetrates the interior of the cavity (1). As a result, the percussion body (2) has high inertial energy at the start of the massage / stimulation, and the movement of the drive module provides a forward driving force (enhancing the percussion effect), thus making the percussion effect more pronounced. From the perspective of commercial manufacturing of massagers, this embodiment can reduce the power requirements of the drive module as well as the requirements for energy storage, control, and other system requirements, thereby lowering costs. Design 3:
[0024] The cavity (1) has a second opening (4); the knocking body (2) has a second knocking surface; wherein the second knocking surface has a second extreme position; and the second extreme position is the extreme position at which the second knocking surface can project out of the cavity (1) through the second opening (4) by at least one degree of freedom A.
[0025] In this embodiment, the tapping surface is enlarged by adding a second opening. The additional tapping surfaces do not affect the energy consumption of the massage device or the tapping effect of the first opening (3), since the energy accumulation occurs in a single direction of movement. This embodiment makes it possible to increase the massage and stimulation effects when used in inserted or fully enclosed massage devices. Design 4:
[0026] The drive knock arrangement (5) comprises: • a drive module; • an eccentric wheel module; • wherein the drive module is configured to rotate the eccentric wheel module; • the drive end (23) has an eccentric wheel guide; • The eccentric wheel guide is connected to the eccentric wheel in a first tuning mode; and • The rotation of the eccentric wheel causes the knocking body (2) to have at least one degree of freedom A for a back-and-forth movement relative to the connecting seat.
[0027] This embodiment primarily offers a solution for the drive arrangement of the contact massage percussion device. The adjustment of the eccentric wheel module and the associated guide structure for converting the rotation into a reciprocating motion can be achieved using a simple and reliable force such as a drive motor to realize the reciprocating movement of the percussion body (2). Design 5:
[0028] The connection mode of the guide of the eccentric wheel and the eccentric wheel module has a further adjustment mode; and the rotation of the eccentric wheel causes the knocking body (2) to have at least one degree of freedom B for a back-and-forth movement relative to the connection seat.
[0029] In this embodiment, the introduction of the connection type of the eccentric wheel guide and the eccentric wheel module achieves a variety of adjustment modes (the first adjustment mode should be considered as other types of adjustment that differ from the first type of adjustment; it can be one type or several types), and the change in the freedom of movement (path of motion) of the tapping body (2) is achieved through different adjustment modes. If such a modification is applied to a massage device, the adjustment of massage modes and industrial adaptation to several models, etc., can be realized, and multifunctionality or multiple modes of the massage devices can be implemented to achieve the output of various massage / stimulation effects.Intelligent control programs can also be combined to create a dynamic / intelligent process, providing a basic hardware platform with stronger features for product variety and performance improvements. Design 6:
[0030] In degree of freedom B, the first tapping surface (21) exhibits: • a third extreme position; • where the third extreme position • the extreme position is in which the first knocking surface (21) can protrude from the cavity (1) through the first opening (3) in at least one movement section of the degree of freedom B; and • a distance b1 between the first tapping surface (21) and the plane of the first opening (3) is smaller than the distance a1 between the first tapping surface (21) and the plane of the first opening (3) at the first extreme position. Design 7:
[0031] In degree of freedom B, the second tapping surface exhibits: • a fourth extreme position; • where the fourth extreme position • the extreme position is in which the second knocking surface can protrude from the cavity (1) through the second opening (4) in at least one movement section of the degree of freedom B; and • a distance b2 between the second tapping surface and the plane of the second opening (4) is smaller than the distance a2 between the second tapping surface and the plane of the second opening (4) in the second extreme position.
[0032] Embodiments 6 and 7 are implementations of embodiment 5, such that the tapping device has different degrees of freedom, thereby achieving different tapping / stimulation effects. With regard to massage stimulation, different positions are generally used during a massage procedure, with different positions producing different stimulation sensations. The adaptability of the tapping motion can meet these requirements. For example, the tapping and stimulation effects differ considerably between bones and muscles. Design 8:
[0033] The knocking device includes: • an elastic energy storage element; and • The elastic energy storage element is configured to absorb kinetic energy that is directly exerted and / or transferred by the knocking drive arrangement (5) when the movement of the knocking body (2) is hindered by a first damping M1 within degree of freedom A and / or degree of freedom B.
[0034] Since the massage stimulation effect of the percussion device is generated by the impact of the percussion body (2) on the target object, but the point of impact is not fixed, different users have different stimulation requirements, and the impact positions of the percussion body (2) also vary. If both the percussion body (2) and the drive assembly are made of rigid materials (similar to materials of a rigid body whose deformation variables can be neglected), the drive assembly can become jammed, leading to failure of the percussion device, which is also one of the main problems of the percussion device. A general solution to this problem is to shorten the jamming path, for example, by minimizing the vibration amplitudes of vibration products.While vibration products use the method of changing the vibration frequency to enhance the sensation of stimulation, this cannot replace the realization of the actual tapping effect, as a small amplitude leads to poor stimulation effects.
[0035] The general frequency of a reciprocating percussion massager is far lower than that of a vibrating product, but its percussion amplitude and intensity differ significantly, so the resulting massage stimulation effect is obviously different. This embodiment aims to achieve a true percussive massage and provides a solution to the problem of the percussive element encountering an obstacle in any extreme position. In this solution, the elastic energy storage element is configured to buffer energy storage when the percussive surface is obstructed, allowing it to be positioned along a transmission path for any force. At the same time, the function of the elastic energy storage element extends far beyond simply buffering energy storage in the event of obstruction.It has a further advantageous effect, namely that the reciprocating tapping body (2) definitely undergoes acceleration, deceleration, and other processes during its oscillation. At an extreme position, the theoretical velocity of the tapping body (2) is zero. If the tapping device relies solely on the eccentric structure for transmission, it generally achieves a reciprocating oscillation similar to that of a pendulum. This type of oscillation has the disadvantage that the velocity of the tapping body (2) is low at a position where contact is required (when the tapping surface is near the end position), thus entering the deceleration process, and the tapping effect is naturally poor. The elastic energy storage element of this embodiment can store energy during the drive process.The energy-storing deformation of the elastic energy storage element allows the maximum speed (peak velocity position) of the tapping body (2) to be shifted during the reciprocating motion to a position closer to the extreme position of the tapping surface, thereby significantly improving the effect of the tapping massage. Furthermore, the energy storage process of the elastic energy storage element also eliminates the impact on the drive and transmission system when the tapping body (2) is moved back and forth and changes direction (the energy loss caused by the impact is relatively large), so that the energy can be released explosively at the moment of the tapping motion. Design 9:
[0036] The first damping M1 is not less than m times the second damping M2; • where the second damping M2 is the damping that the object being acted upon exerts on the tapping surface during normal use of the tapping device; and • the range of values is from m 1.2 to 4.
[0037] This embodiment is based on embodiment 8, which defines a proportional relationship between the first damping element M1 and the second damping element M2. This embodiment demonstrates the improvement that the rigid transmission and the percussive force are transmitted more completely. The object to be massaged generally consists of flesh / muscle and is flexible / elastic compared to the percussive element (2), and different settings of the elastic elements during the transmission process produce different percussive effects.For example, if the equivalent damping formed by the elastic energy storage element is low (less than or equal to the reaction damping generated by the object being massaged), the tapping energy can be absorbed by the elastic energy storage element when the tapping body (2) comes into contact with the object being massaged. This results in insufficient energy being applied to the massage area and a significant reduction in the tapping effect. This embodiment specifies an equivalent damping ratio of at least 1.2. Practical experience has shown that this allows the tapping energy to be transferred effectively and results in a significant reduction in blockages. Increasing the equivalent damping ratio to a factor of 3 to 4 further improves the tapping effects and significantly enhances the stimulation; however, some resistance may arise during high-frequency reciprocating movements of the tapping body.With a ratio greater than 4, the inertial damping during the back-and-forth motion increases, and the energy losses during the motion increase accordingly. Design 10:
[0038] The elastic energy storage element exhibits: • at least two sets of elastic energy storage units; and • wherein the elastic energy storage units are arranged at any position on a force transmission connection from the drive arrangement (5) to the first and / or second knocking surface. Design 11:
[0039] In this embodiment • k sets of elastic energy storage units provided, where no integer is greater than or equal to 2; • where the i-th set of elastic energy storage units Ni can provide a damping Pi, with 1≤i≤k; • Pi is an equivalent damping that the i-th set of elastic energy storage units transfers from the drive arrangement to the knocking surface; • where there exists an index j such that Pj≠Pi; and • where 1 ≤ j ≤ k and j ≠ i.
[0040] Embodiments 10 and 11 provide multiple sets of elastic energy storage elements with different damping characteristics. The difference between the elastic energy storage elements should be considered as an obvious difference in the equivalent elastic damping generated in the system. Generally, a difference of at least 1.2 times is considered an obvious difference. The obvious difference between at least one set of elastic damping elements is that the elastic energy storage element with higher damping behaves rigidly in most cases (in a state without energy storage), but can temporarily store energy or prevent stalling when greater damping or an occasional collision occurs, thereby significantly improving the stability of the system and the user experience.
