Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and in particular to a massage device. Background Technology

[0002] A fascia gun is a common massage device that primarily uses high-frequency vibrations to act on receptors in muscles, tendons, and joint capsules, producing a significant massage effect. This tool can effectively relieve muscle-related pain, increase the body's pain tolerance threshold, and reduce lactic acid buildup in muscles after exercise. Especially after exercise, using a fascia gun can help quickly relieve muscle soreness and significantly shorten muscle recovery time, providing great convenience for sports enthusiasts and fitness enthusiasts.

[0003] However, most fascia guns on the market are pistol-style. When massaging areas away from the user's front, such as the back, the user's hand usually needs to bend significantly to massage certain areas, making some areas difficult to reach or resulting in poor massage effects. In other words, these fascia guns have certain limitations in use, restricting their application scenarios and target users, and failing to meet the diverse needs of users in different situations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art, thereby providing a massage device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A massage device includes a main body, a reciprocating drive assembly, a massage head, and a handle. The reciprocating drive assembly is mounted on the main body, and its power output end is connected to the massage head. The handle is for a user to hold. It also includes an extended connection part; One end of the extension connection is connected to the main body, and the other end extends toward the main body near the massage head and is connected to the handle.

[0006] In the above design, the main body and handle are connected by an extension connector, and the massage head and handle are located on the same side. This allows the arm to maintain a natural bent angle (similar to the everyday posture of raising your hand to scratch your back), making it easier for the user to massage their back. Furthermore, because the massage head and handle are on the same side, it is easier for the user to control the pressure direction of the massage head to be perpendicular to their back, improving the massage effect. Simultaneously, the force applied by the hand to the handle is also more effectively directed along the axis of the massage head, ensuring it fits snugly against the user's back and preventing it from deviating or shifting, further enhancing the massage effect.

[0007] Preferably, the longest distance from the massage head to the connection point between the extension connection and the main body is H1, and the longest distance from the handle to the connection point between the extension connection and the main body is H2, then H1 < H2; and / or; One end of the handle portion has an abutting end face that abuts against the extended connecting portion, and the end of the massage head away from the reciprocating drive assembly is located on the plane where the abutting end face is located.

[0008] In the above design, the handle is relatively further away from the main body, meaning it's closer to the user than the massage head. This arrangement allows the handle to be closer to the user's front when the massage head touches the user's back. When the user holds it, the degree of hand bending can be further reduced, making it easier to grip and apply force to the massage head, allowing it to better conform to the user's back and improve the massage effect. Furthermore, the end of the massage head furthest from the reciprocating drive assembly is located on the contact surface of the handle. That is, one end of the massage head is flush with the end where the handle and extension connection are located. This not only facilitates gripping but also ensures more even force distribution during use.

[0009] Preferably, the extended connection includes a metal elastic plate and a protective sleeve fitted over the outside of the metal elastic plate; At least two ends of the metal elastic plate are fixedly connected to the main body and the handle portion, respectively. The metal elastic plate includes a bending section; Under stress, the bent segment can deform; under free state, the bent segment returns to its original position.

[0010] In the above solution, the metal elastic plate can undergo a certain degree of bending deformation under force. This means that when the user uses the massage device, the bending angle between the massage head and handle can be adjusted appropriately according to the massage position and grip position to create an angle suitable for massaging the back. In other words, this design is both user-friendly and enhances the massage effect.

[0011] Preferably, the curved segment is arc-shaped, and when the curved segment is in a free state, its corresponding central angle is 90°; the deformation range of the curved segment is 80°-100°.

[0012] In the above design, the curved section is arc-shaped and 90° in its free state, allowing the massage head and handle to extend in approximately the same direction, making the massage device structure more compact. Compared to a corrugated shape, the arc shape provides structural strength and facilitates its rebound and recovery. By appropriately setting the deformation range of the curved section, excessive deformation can be avoided, and its applicability can be broadened, enabling effective massage of different positions.

[0013] Preferably, the metal elastic plate further includes a first straight plate segment and a second straight plate segment respectively connected to both ends of the bent section; The first straight section is fixedly connected to the main body by a first fastening structure; The second straight section is fixedly connected to the handle section by a second fastening structure.

[0014] In the above solution, the first and second straight plate segments are designed to facilitate the connection of both ends of the metal elastic plate to the main body and the handle, respectively (e.g., pre-insertion followed by connection using a fastening structure). Furthermore, the metal elastic plate serves as the primary connecting structure, with the first and second straight plate segments at both ends, and both segments being fixedly connected to the main body and handle via a first and second fastening structure, respectively, thereby enhancing the overall stability of the massage device.

[0015] Preferably, the first fastening structure includes a fixing plate, a first fixing hole, a first fastener, a surrounding part, and a reinforcing rib plate; The fixing plate abuts against the first straight plate segment; The first fixing hole penetrates the fixing plate and the first straight plate section, so that the first fastener can pass through and fix the fixing plate and the first straight plate section; The surrounding portion is arranged around the outside of the fixing plate, and an insertion limiting groove is formed on the side of the fixing plate facing the first straight plate segment, and a clearance area is formed on the side of the fixing plate away from the first straight plate segment corresponding to the reinforcing rib plate; Two reinforcing ribs are symmetrically arranged about the first fixing hole, and an installation groove for installing the first fastener is formed between the two reinforcing ribs.

[0016] In the above scheme, the fixing plate abuts against the first straight plate segment and is connected by the first fastener, which increases the contact area between the two and improves the stability of the connection. The surrounding portion serves two purposes: firstly, it cooperates with the fixing plate to form an insertion limiting groove, limiting the first straight plate segment after insertion; secondly, it surrounds the outer periphery of the fixing plate, reinforcing it and increasing its stability. The reinforcing rib is located on the side away from the first straight plate segment and forms a receiving groove for the first fastener, thereby reinforcing the area of ​​the fixing plate near the first fastener and further ensuring the structural stability of the fixing plate, preventing breakage in the area corresponding to the first fixing hole. Furthermore, the surrounding portion has a clearance area corresponding to the reinforcing rib area, thus preventing the surrounding portion from affecting the installation of the first fastener, especially when there are several first fasteners along the length of the fixing plate.

[0017] Preferably, the handle portion includes a first handle housing and a second handle housing disposed opposite to each other; The second fastening structure includes a limiting slot, a pressing protrusion, a second fixing hole, and a second fastener; The limiting slot is provided on the first handle housing, the pressing protrusion is provided on the second handle housing, and when the first handle housing and the second handle housing are engaged, the pressing protrusion presses the second straight plate segment into the limiting slot; The second fixing hole passes through the first handle housing, the second straight plate section and the second handle housing in sequence, so that the second fastener passes through and fixes the first handle housing, the second straight plate section and the second handle housing.

[0018] In the above solution, the limiting slot and the pressing protrusion cooperate to limit the second straight plate segment, thereby improving the stability of the connection between the second straight plate segment and the handle part. It can also prevent the second straight plate segment from undergoing torsional deformation, which would cause the first handle housing and the second handle housing to separate. Furthermore, it can prevent the torsional deformation of the second straight plate segment from spreading to the bending segment and affecting the performance of the bending segment.

[0019] Preferably, the extension length of the first straight section is L1, and the extension length of the second straight section is L2, then 5 / 3 < L2 / L1 < 5 / 2; The second fastening structure also includes a third fixing hole, a connecting post, and a third fastener; The third fixing hole penetrates the second straight plate section and is located on the side of the second fixing hole away from the curved section; The connecting post is fixedly connected to the first handle housing or the second handle housing; The third fastener passes through the third fixing hole and is fixedly connected to the connecting post to fix the second straight plate segment.

[0020] In the above scheme, the ratio range of the first straight section and the second straight section is reasonably set, which not only makes it convenient for users to hold, but also helps to improve the stability between the main body and the handle.

[0021] Furthermore, due to the relatively long length of the second straight section, the addition of the third fixing hole, third fastener, and connecting post increases the number of connection points, thereby improving the stability of the second straight section's installation. In addition, since the second fixing hole and second fastener need to simultaneously secure the first handle housing, second handle housing, and second straight section, the main connection structure ensuring a stable connection between the handle and the second straight section features mutually cooperating limiting grooves and pressing protrusions, as well as mutually cooperating third fixing holes, third fasteners, and connecting posts distributed along a direction away from the curved section, further enhancing the securing effect of the second straight section. Moreover, during installation, the third fixing hole, third fastener, and connecting post can be used to pre-position the second straight section with either the first or second handle housing, facilitating the assembly of the first and second handle housings and the second straight section.

[0022] Preferably, the two ends of the protective sleeve are respectively inserted into the main body and the handle portion, and the two ends of the protective sleeve are respectively arranged around the outside of the main body and the handle portion; And / or, the metal elastic plate is configured as an elastic steel plate, and the thickness of the elastic steel plate is in the range of 2mm-4mm.

[0023] In the above solution, the protective cover is inserted into the main body and the handle, which facilitates the assembly of the massage device. When the main body or the handle is set separately, the protective cover can be wrapped around the outside of the main body and the handle to achieve radial limitation of the main body and the handle, further improving the stability of the structure.

[0024] Preferably, it also includes at least two batteries, which are respectively installed in the main body and the handle.

[0025] In the above design, the arrangement of installing two batteries, one on the main body and the other on the handle, allows the center of gravity of the massage device to be located between the main body and the handle, thereby balancing the forces between the two parts and making it easier for the user to hold. Furthermore, the two batteries working together can serve as backups for each other, extending the usage time of the massage device.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The main body and handle are connected by an extension joint, placing the massage head and handle on the same side. This allows the arm to maintain a natural bent angle (similar to the everyday posture of raising your hand to scratch your back), making it easier for users to massage their backs. Furthermore, because the massage head and handle are on the same side, it's easier for users to control the massage head's pressure direction to be perpendicular to their backs, enhancing the massage effect. Simultaneously, the force applied by the hand to the handle is also more effectively directed along the axis of the massage head, ensuring it adheres closely to the user's back and preventing it from shifting or deviating, further improving the massage effect.

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] See Figures 1 to 14 This invention provides a massage device, including a main body 1, a reciprocating drive assembly 2, a massage head 3, and a handle 4. The reciprocating drive assembly 2 is mounted on the main body 1, and its power output end is connected to the massage head 3. The handle 4 is connected to the main body 1 for use by a user.

[0047] See Figures 1 to 4 The reciprocating drive assembly 2 includes a motor 21 and a transmission assembly. The transmission assembly includes an eccentric block 22, a transmission connecting plate 23, a transmission rod 24, and a connecting rod 25. The motor 21, eccentric block 22, transmission connecting plate 23, transmission rod 24, connecting rod 25, and massage head 3 are sequentially connected to drive the massage head 3 to reciprocate, thereby providing a massage to the user.

[0048] Specifically, the transmission connecting plate 23 is installed in the groove provided on the transmission rod 24, and the end of it away from the groove opening is connected to the eccentric block 22 to achieve a stable connection. The end of the transmission rod 24 away from the transmission connecting plate 23 is connected to the connecting rod 25. The end of the connecting rod 25 that extends out of the inner cavity of the main body 1 has a thread so that the massage head 3 can be threadedly connected to the connecting rod 25. In addition, an anti-loosening washer 26 can be provided between the massage head 3 and the connecting rod 25 to ensure that the massage head 3 and the connecting rod 25 are detachable and stably connected.

[0049] Furthermore, the transmission rod 24 and the connecting rod 25 are detachably connected via a connecting assembly 27. In this embodiment, the connecting assembly 27 includes a first limiting hole 271, a second limiting hole 272, a limiting pin 273, a limiting protrusion 274, a guide channel 275, a limiting channel 276, and an elastic pressing part 277. The first limiting hole 271 and the second limiting hole 272 are respectively disposed on the transmission rod 24 and the connecting rod 25, and the first limiting hole 271 and the second limiting hole 272 are respectively arranged radially along the transmission rod 24 and the connecting rod 25 and pass through their central axes. The limiting pin 273 can pass through the first limiting hole 271 and the second limiting hole 272 when they are aligned, so as to realize the axial limiting connection between the transmission rod 24 and the connecting rod 25. A limiting protrusion 274 is provided on the connecting rod 25 and can move along the guide channel 275 to the limiting channel 276. When the limiting protrusion 274 rotates within the limiting channel 276 to abut against the end of the limiting channel 276 away from the guide channel 275, the first limiting hole 271 and the second limiting hole 272 are aligned. That is, the limiting pin 273, the limiting protrusion 274, the guide channel 275, and the limiting channel 276 cooperate with each other to achieve the alignment of the first limiting hole 271 and the second limiting hole 272, so as to facilitate the installation of the limiting pin 273, and to achieve dual limiting of the transmission rod 24 and the connecting rod 25, ensuring connection stability. The elastic compression part 277 is provided on the transmission rod 24 and the connecting rod 25. It can not only achieve axial compression and pressing between the two, but also utilize the contact between the ball formed on the outer periphery of the elastic compression part 277 and the main body 1, thereby enabling the connecting rod 25 and the massage head 3 to move in a preset direction, reducing the vibration of the massage device and improving the massage effect.

[0050] See Figures 1 to 9 The massage device also includes an extension connection 5, one end of which is connected to the main body 1, and the other end extends toward the end of the main body 1 near the massage head 3 and is connected to the handle 4.

[0051] It's easy to understand that the main body 1 and the handle 4 are connected by an extension connector 5, and the massage head 3 and handle 4 are located on the same side. This allows the arm to maintain a natural bent angle (similar to the everyday posture of raising your hand to scratch your back), making it easier for the user to massage their back. Furthermore, because the massage head 3 and handle 4 are on the same side, it's easier for the user to control the pressure direction of the massage head 3 to be perpendicular to their back, improving the massage effect. Simultaneously, the force applied by the hand to the handle 4 is also more concentrated along the axis of the massage head 3, ensuring the massage head 3 fits snugly against the user's back and preventing it from deviating or moving, further enhancing the massage effect.

[0052] Furthermore, the longest distance from the massage head 3 to the connection point of the extension connecting part 5 and the main body 1 is H1, and the longest distance from the handle part 4 to the connection point of the extension connecting part 5 and the main body 1 is H2, then H1 < H2; that is, the handle part 4 is relatively farther away from the main body 1, and the handle part 4 is closer to the user side than the massage head 3. This arrangement makes the handle part 4 closer to the user's front when the massage head 3 touches the user's back. When the user holds it, the degree of hand bending can be further reduced, making it easier for the user to hold and apply force to the massage head 3, so that the massage head 3 better fits the user's back and improves the massage effect.

[0053] Furthermore, one end of the handle portion 4 has an abutment end face 40 that abuts against the extension connection portion 5, and the end of the massage head 3 away from the reciprocating drive assembly 2 is located in the plane of the abutment end face 40 (see...). Figure 6 On the plane where the dashed line S is located, that is, the end of the massage head 3 is flush with the end where the handle part 4 and the extension connection part 5 are connected, which makes it easier for the user to hold and makes the massage device more evenly stressed during use.

[0054] See Figure 2 , Figure 3 as well as Figures 5 to 9 The extension connection part 5 includes a metal elastic plate 51, with both ends of the metal elastic plate 51 fixedly connected to the main body 1 and the handle part 4, respectively, to achieve a stable connection between the main body 1 and the handle part 4. The metal elastic plate 51 includes a bending section 510, which can deform under stress and return to its original position under free state.

[0055] It is easy to understand that the metal elastic plate 51 can undergo a certain degree of bending deformation when subjected to force. That is, when the user uses the massage device, the bending angle between the massage head 3 and the handle 4 can be appropriately adjusted according to the massage position and grip position to form an angle that is convenient for massaging the back. In other words, this setting is both beneficial to the user's operation and can improve the massage effect.

[0056] Specifically, the curved section 510 is arc-shaped, and when the curved section 510 is in a free state, its corresponding central angle is 90°, so that the massage head 3 and the handle 4 can extend in approximately the same direction, making the massage device structure more compact. Furthermore, compared to a corrugated shape, the arc-shaped curved section 510 has a certain structural strength and is easy to rebound and reset. At the same time, it can also avoid the situation where adjacent corrugated sections of the curved section 510 squeeze each other, which may affect other structures (such as squeezed wires).

[0057] Furthermore, the deformation range of the bending segment 510 is 80°-100°, that is, the bending segment 510 can be deformed to a central angle of 80°, 85°, 95° or 100°, etc. By reasonably setting the deformation range of the bending segment 510, excessive deformation can be avoided, and its application range can be made wider, enabling effective massage of different positions.

[0058] Furthermore, the metal elastic plate 51 also includes a first straight plate segment 511 and a second straight plate segment 512 respectively connected to both ends of the bending section 510; the first straight plate segment 511 is fixedly connected to the main body 1 by a first fastening structure 6; and the second straight plate segment 512 is fixedly connected to the handle part 4 by a second fastening structure 7.

[0059] It is easy to understand that the first straight plate segment 511 and the second straight plate segment 512 are designed to facilitate the connection of both ends of the metal elastic plate 51 to the main body 1 and the handle part 4 respectively (e.g., pre-insertion followed by connection using a fastening structure). The metal elastic plate 51 is the main connecting structure, and the first straight plate segment 511 and the second straight plate segment 512 are provided at both ends of the metal elastic plate 51. Both are fixedly connected to the main body 1 and the handle part 4 respectively through the first fastening structure 6 and the second fastening structure 7, which can improve the overall stability of the massage device.

[0060] To elaborate further, if the extension length of the first straight section 511 is L1 and the extension length of the second straight section 512 is L2, then 5 / 3 < L2 / L1 < 5 / 2, for example, L2 / L1 = 2.

[0061] It is easy to understand that by reasonably setting the ratio range of the first straight section 511 and the second straight section 512, it is not only convenient for users to hold, but also conducive to improving the stability between the main body 1 and the handle part 4.

[0062] Furthermore, the metal elastic plate 51 is set as an elastic steel plate, and the thickness of the elastic steel plate is in the range of 2mm-4mm, such as 2mm, 3mm or 4mm, etc.

[0063] See Figure 2 , Figure 3 as well as Figures 5 to 9The extended connection part 5 also includes a protective sleeve 52 sleeved on the outside of the metal elastic plate 51. The protective sleeve 52 can prevent the user from being injured during the deformation of the metal elastic plate 51, thus improving the user experience.

[0064] It is worth noting that the protective sleeve 52 is preferably made of injection molding, which can produce slight bending deformation, and its two ends are respectively inserted and matched with the main body 1 and the handle part 4. The protective sleeve 52 is not directly fixed to the metal elastic plate 51 so as not to affect the bending deformation of the metal elastic plate 51.

[0065] Furthermore, the two ends of the protective cover 52 are respectively arranged around the outside of the main body 1 and the handle part 4, which is conducive to the assembly of the massage device (that is, it is conducive to the assembly of the protective cover 52 with the main body 1 and the protective cover 52 with the handle part 4).

[0066] Furthermore, the handle portion 4 includes a first handle housing 41 and a second handle housing 42 disposed opposite to each other; the first handle housing 41 and the second handle housing 42 are connected to each other to form an installation chamber, and one end of the protective sleeve 52 is disposed around the outside of the first handle housing 41 and the second handle housing 42 and abuts against the first handle housing 41 and the second handle housing 42. Thus, the protective sleeve 52 can be used to achieve radial limiting of the first handle housing 41 and the second handle housing 42, thereby increasing the stability of the connection between the first handle housing 41 and the second handle housing 42, and further improving the installation stability of the structures installed in the installation chamber (such as the second battery 200, the counterweight 8, etc. mentioned later).

[0067] Furthermore, the outer wall surfaces of the first handle housing 41 and the second handle housing 42 are partially recessed to form an annular groove 43; the inner wall surface of the protective sleeve 52 has an annular protrusion 521, and when the protective sleeve 52 surrounds the handle portion 4, the annular protrusion 521 engages with the annular groove 43. It is easy to understand that the annular groove 43 and the annular protrusion 521 restrict the relative sliding of the protective sleeve 52 and the handle portion 4 along the axial direction, thereby improving the stability of the connection between them and facilitating installation.

[0068] To further facilitate the docking and installation of the protective cover 52 and the handle part 4, the first handle housing 41 and the second handle housing 42 are provided with a guide conical surface 44 at one end facing the extension connection part 5, and the diameter of the guide conical surface 44 gradually decreases from the installation direction of the extension connection part 5.

[0069] The first fastening structure 6 can be configured in various ways, as long as it can achieve a stable connection between the first straight plate segment 511 and the main body 1. Similarly, the second fastening structure 7 can also be configured in various ways, as long as it can achieve a stable connection between the second straight plate segment 512 and the handle part 4.

[0070] See Figure 2 , Figure 3 as well as Figures 5 to 9 In this embodiment, the first fastening structure 6 includes a fixing plate 61, a first fixing hole 62, and a first fastener 63. The fixing plate 61 (end face) abuts against the first straight plate segment 511 (end face), and the first fixing hole 62 penetrates through the fixing plate 61 and the first straight plate segment 511, allowing the first fastener 63 to pass through and fix the plate 61 and the first straight plate segment 511. It is worth noting that the abutment between the fixing plate 61 (end face) and the first straight plate segment 511 (end face) increases the contact area between the two, thereby effectively improving the stability of the connection between them.

[0071] Furthermore, the first fastening structure 6 also includes a surrounding portion 64, which surrounds the outside of the fixing plate 61 and forms an insertion limiting groove 66 on the side of the fixing plate 61 facing the first straight plate segment 511. It is easy to understand that the surrounding portion 64 is provided in two ways: firstly, it can cooperate with the fixing plate 61 to form the insertion limiting groove 66, thereby limiting the first straight plate segment 511 after insertion; secondly, it surrounds the outer periphery of the fixing plate 61, thereby reinforcing the fixing plate 61 and increasing its stability.

[0072] Furthermore, the first fastening structure 6 also includes reinforcing ribs 65. Two reinforcing ribs 65 are symmetrically arranged about the first fixing hole 62, and an installation groove 67 for the first fastener 63 is formed between the two reinforcing ribs 65, so that the reinforcing ribs 65 can reinforce the area of ​​the fixing plate 61 near the first fastener 63, further ensuring the structural stability of the fixing plate 61 and preventing the fixing plate 61 from breaking in the area corresponding to the first fixing hole 62.

[0073] Furthermore, the surrounding portion 64 forms a clearance area on the side of the fixing plate 61 away from the first straight plate segment 511, corresponding to the reinforcing rib plate 65. That is, the surrounding portion 64 is disconnected at the corresponding mounting groove 67, so that the lower opening of the mounting groove 67 is enlarged, avoiding interference of the surrounding portion 64 with the installation of the first fastener 63, especially when there are several first fasteners 63 along the length direction of the fixing plate 61.

[0074] See Figure 2 , Figure 3 as well as Figures 5 to 9In this embodiment, the second fastening structure 7 includes a limiting groove 71, a pressing protrusion 72, a second fixing hole 73, and a second fastener 74. The limiting groove 71 is disposed on the first handle housing 41, and the pressing protrusion 72 is disposed on the second handle housing 42. When the first handle housing 41 and the second handle housing 42 are engaged, the pressing protrusion 72 presses the second straight plate segment 512 into the limiting groove 71. The second fixing hole 73 passes through the first handle housing 41, the second straight plate segment 512, and the second handle housing 42 in sequence, so that the second fastener 74 can pass through and fix the first handle housing 41, the second straight plate segment 512, and the second handle housing 42.

[0075] It is easy to understand that by the cooperation of the limiting slot 71 and the pressing protrusion 72, the second straight plate segment 512 can be limited, which can improve the stability of the connection between the second straight plate segment 512 and the handle part 4. It can also prevent the second straight plate segment 512 from undergoing torsional deformation, which would cause the first handle housing 41 and the second handle housing 42 to separate. It can also prevent the torsional deformation of the second straight plate segment 512 from spreading to the bending segment 510 and affecting the performance of the bending segment 510. Furthermore, since the second straight plate segment 512 is relatively long (see L2 / L1=2 above), and the second straight plate segment 512 is connected to the handle portion 4, in order to increase the stability of the connection between the second straight plate segment 512 and the handle portion 4, the second fastening structure 7 also includes a third fixing hole 75, a connecting post 76, and a third fastener 77; the third fixing hole 75 passes through the second straight plate segment 512 and is located on the side of the second fixing hole 73 away from the crimping protrusion 72; the connecting post 76 is fixedly connected to the first handle housing 41 or the second handle housing 42; the third fastener 77 passes through the third fixing hole 75 and is fixedly connected to the connecting post 76 to fix the second straight plate segment 512.

[0076] It is easy to understand that the arrangement of the third fixing hole 75, the third fastener 77, and the connecting post 76 can improve the stability of the second straight plate segment 512 installation by increasing the number of connection points. Furthermore, since the second fixing hole 73 and the second fastener 74 need to simultaneously achieve the fixed connection of the first handle housing 41, the second handle housing 42, and the second straight plate segment 512, the main connection structure ensuring a stable connection between the handle part 4 and the second straight plate segment 512 distributes the mutually cooperating limiting groove 71 and pressing protrusion 72, the mutually cooperating third fixing hole 75, the third fastener 77, and the connecting post 76 in a direction away from the bending section 510. This further improves the fixing effect of the second straight plate segment 512 and enhances the connection stability of the second fixing hole 73 and the second fastener 74.

[0077] Furthermore, during installation, the third fixing hole 75, the third fastener 77 and the connecting post 76 can be used to achieve the pre-positioning of the second straight plate segment 512 with the first handle housing 41 or the second handle housing 42, which facilitates the assembly of the first handle housing 41, the second handle housing 42 and the second straight plate segment 512.

[0078] It is worth noting that in this embodiment, the first fastener 63, the second fastener 74 and the third fastener 77 can be selected as screws or bolts according to actual needs. The corresponding first fixing hole 62, the second fixing hole 73 and the third fixing hole 75 can also be set as through holes or threaded holes according to their setting positions. The connecting post 76 can be set as a threaded post or an annular post with a through hole, etc. The specific settings can be made according to actual needs, as long as the fixing effect can be achieved.

[0079] See Figure 1 and Figure 2 The massage device also includes a counterweight 8, which is installed inside the handle 4. By increasing the weight of the counterweight 8, the center of gravity of the massage device can be adjusted to the area between the massage head 3 and the handle 4.

[0080] It is easy to understand that the center of gravity of the entire massage device can be adjusted by setting the counterweight 8, so that the user can use it with less effort and the massage effect is better. In addition, the counterweight 8 is installed in the handle part 4, which facilitates the installation of the counterweight 8, balances the weight of the reciprocating drive assembly 2, and does not interfere with the installation of the reciprocating drive assembly 2.

[0081] Furthermore, the first handle housing 41 and the second handle housing 42 are connected to each other and form a receiving area for accommodating the counterweight 8; the counterweight 8 is detachably installed within the receiving area. It is easy to understand that designing the handle 4 as a split structure, and allowing the counterweight 8 to be detachably installed within the handle 4, facilitates the assembly of the handle 4 and the counterweight 8. Moreover, the weight of the counterweight 8 can be adjusted according to the weight of the corresponding area of ​​the main body 1 and the weight of the handle 4.

[0082] Since existing massage devices are typically powered by a single battery, their usage time is limited and often fails to meet users' needs for extended use.

[0083] See Figures 1 to 14 In this embodiment, the massage device further includes at least two batteries, namely a first battery 100 and a second battery 200, so that the first battery 100 and the second battery 200 can serve as backups for each other, thereby increasing the single-use time of the massage device. Of the first battery 100 and the second battery 200, one is installed inside the main body 1 and the other is installed inside the handle part 4. This embodiment will be described with the first battery 100 installed inside the main body 1 and the second battery 200 installed inside the handle part 4 as an example.

[0084] Specifically, in order to facilitate the assembly of the first battery 100, the reciprocating drive assembly 2 and the main body 1, the main body 1 includes a first housing 11 and a second housing 12 connected to each other; the reciprocating drive assembly 2 is connected to the first housing 11, the first battery 100 is connected to the second housing 12, and the area of ​​the reciprocating drive assembly 2 (specifically its transmission rod 24) corresponding to the first battery 100 extends away from the first battery 100 to form a clearance area, so as to avoid interference between the transmission rod 24 and the first battery 100 during installation, and also to prevent the transmission rod 24 from directly transmitting vibration to the first battery 100 during movement, thus ensuring the stability of the installation of the first battery 100.

[0085] Furthermore, the inner wall of the second housing 12 is provided with a fixing post 121 and a positioning strip 122 protruding from it; the massage device also includes a battery limiting plate 700, which is connected to the fixing post 121 to fix the first battery 100 to the second housing 12; when the first battery 100 is fixed to the second housing 12, the positioning strip 122 is formed on the periphery of the first battery 100 to achieve stable installation of the first battery 100 and the second housing 12.

[0086] It is easy to understand that the main body 1 is set as a split first shell 11 and second shell 12, and the reciprocating drive assembly 2 and the first battery 100 are respectively connected to the first shell 11 and the second shell 12, which facilitates the installation of the first battery 100 and the reciprocating drive assembly 2.

[0087] Furthermore, the main body 1 also includes a threaded platform 13, a reinforcing platform 14, and a cover 15; the threaded platform 13 and the reinforcing platform 14 are partially formed on the first housing 11 and partially formed on the second housing 12; the cover 15 includes a threaded connecting section 151 and a reinforcing ring 152, the threaded connecting section 151 is threadedly connected to the threaded platform 13 and is located radially outside the threaded platform 13; the end face of the reinforcing platform 14 away from the threaded platform 13 is supported on the end of the reinforcing ring 152.

[0088] It is easy to understand that the cover 15 is connected to the radial outer side of the threaded platform 13, which can limit the radial movement of the first housing 11 and the second housing 12, improving the engagement effect and connection stability. Furthermore, the end of the reinforcing platform 14 is supported by the end of the reinforcing ring 152, which can achieve axial limiting, thereby preventing axial loosening to a certain extent and further improving the stability of the connection between the various parts of the main body 1.

[0089] Furthermore, the edges of the first housing 11 and the second housing 12 abut against each other for sealing, and several intermittently spaced snap fasteners can be provided on the opposing edges of the two housings to improve the stability of the edge connection. Of course, mutually cooperating positioning pins and positioning holes can also be provided on the opposing edges of the first housing 11 and the second housing 12 to facilitate the assembly of the two and prevent the snap fasteners from breaking due to force applied when misaligned.

[0090] See Figures 1 to 10 The massage device also includes a control circuit 300, which is electrically connected to the first battery 100, the second battery 200, and the reciprocating drive assembly 2 (specifically, the motor 21) to control the first battery 100 and the second battery 200 to supply power to the reciprocating drive assembly 2 in one or a combination of simultaneous power supply and alternating power supply; the control circuit 300 is also used to control the charging of the first battery 100 or the second battery 200 when the first battery 100 or the second battery 200 is in a non-powered state.

[0091] It is easy to understand that the first battery 100 and the second battery 200 can simultaneously and alternately supply power to the reciprocating drive component 2, thereby enabling efficient use of the power of the first battery 100 and the second battery 200. At the same time, it can also control the charging of the first battery 100 or the second battery 200 when the first battery 100 or the second battery 200 is not supplying power, solving the problem of the massage device not being able to charge during use, and thus effectively increasing the continuous use time of the massage device to meet the needs of users for long-term use.

[0092] Furthermore, the control circuit 300 includes a power supply circuit connected between the power source of the reciprocating drive assembly 2 (i.e., the motor 21) and the second battery 200. The power supply circuit is also connected between the power source of the reciprocating drive assembly 2 and the first battery 100. Specifically, the control circuit 300 includes a first power supply circuit 301 and a second power supply circuit 302. The first power supply circuit 301 is connected between the first battery 100 and the motor 21, and the second power supply circuit 302 is connected between the second battery 200 and the motor 21.

[0093] Furthermore, the control circuit 300 also includes a charging port 303, a first charging circuit 304, and a second charging circuit 305; the charging port 303 is used to connect to an external power supply structure; the charging port 303 is connected to the positive and negative terminals of the first battery 100 through the first charging circuit 304; the charging port 303 is connected to the positive and negative terminals of the second battery 200 through the second charging circuit 305.

[0094] It is easy to understand that when the first power supply circuit 301 is turned on (switches S4 and S6 are closed, and the other switches S1, S2, S3, S5, and S6 are closed), the first battery 100 supplies power to the motor 21. When the second power supply circuit 302 (switches S5 and S6 are closed, and the other switches S1-S4 are closed) is turned on, the second battery 200 supplies power to the motor 21. When the charging port 303 is connected to the external power supply structure and the first charging circuit 304 (switches S1 and S3 are on, and the other switches S2, S4, S5, and S6 are turned on), the first battery 100 is charged. When the charging port 303 is connected to the external power supply structure and the second charging circuit 305 is turned on, the second battery 200 is charged.

[0095] It is worth noting that the first power supply circuit 301 and the first charging circuit 304 do not conduct simultaneously, and the second power supply circuit 302 and the second charging circuit 305 do not conduct simultaneously. Other combinations are possible, namely: the first power supply circuit 301 and the second power supply circuit 302 can conduct simultaneously; the first power supply circuit 301 and the second charging circuit 305 can conduct simultaneously; the second power supply circuit 302 and the first charging circuit 304 can conduct simultaneously; and the first charging circuit 304 and the second charging circuit 305 can conduct simultaneously. Furthermore, when switches S1 and S2 are closed, and the other switches S1-S6 are open, the second battery 200 can be used to charge the first battery 100.

[0096] Here, "conduction" means that the circuit is connected to form a closed loop. Power supply circuit and charging circuit also refer to closed loop paths. Wires can be shared between different circuits.

[0097] See Figures 1 to 10 Since the second battery 200 is installed in the handle portion 4 and the motor 21 is installed inside the main body 1, in this embodiment, the metal elastic plate 51 has a smooth surface, and a first wire channel 400 for the second power supply circuit 302 to pass through is formed between the inner wall surface of the protective sleeve 52 and the smooth surface. That is, the side of the metal elastic plate 51 facing the first wire channel 400 is a smooth surface, so as to ensure that the deformation process of the metal elastic plate 51 will not affect some of the wires of the second power supply circuit 302, and to ensure the effective electrical connection of the second power supply circuit 302.

[0098] Furthermore, the first wire channel 400 is located on the side of the metal elastic plate 51 opposite to the preset direction. One end of the first wire channel 400 communicates with the inner cavity of the main body 1 through the first through hole 401, and the other end communicates with the mounting chamber of the handle part 4 through the second through hole 402. The first through hole 401 is formed on the first housing 11, and the second through hole 402 is formed by the first handle housing 41 and the second handle housing 42. To avoid wear on the wire, both the first through hole 401 and the second through hole 402 are rounded.

[0099] Furthermore, the massage device also includes a mounting bracket 500 and a second wire channel 600; the mounting bracket 500 includes a fixed platform 501 and a wire baffle 502; the reciprocating drive assembly 2 is mounted on the fixed platform 501, the wire baffle 502 is fixed on the fixed platform 501, and forms the second wire channel 600 with the main body 1; the wire baffle 502 has a wire hole 503, which connects the second wire channel 600 and the reciprocating drive assembly 2.

[0100] It is easy to understand that by setting the wire baffle 502, the second wire channel 600 and the reciprocating drive assembly 2 can be isolated, thereby preventing the power supply circuit wires from getting stuck between the relatively moving structures of the reciprocating drive assembly 2, so as to ensure the effectiveness of the electrical connection and the stability of the movement of the reciprocating drive assembly 2.

[0101] Furthermore, the wire baffle 502 includes a first arc-shaped baffle 5021 and a second arc-shaped baffle 5022. The first arc-shaped baffle 5021 is located on one side of the motor 21 to separate the motor 21 from the second wire channel 600. The second arc-shaped baffle 5022 is located on one side of the eccentric block 22, the transmission connecting plate 23, and the transmission rod 24 to separate the eccentric block 22, the transmission connecting plate 23, the transmission rod 24, and the second wire channel 600. The wire routing hole 503 is provided on the first arc-shaped baffle 5021, and reinforcing plates 504 are provided on both sides of the wire routing hole 503 to improve the structural strength of the mounting bracket 500.

[0102] This embodiment also provides a control method applicable to the above-mentioned massage device, wherein the massage device has a low-level operation state, a medium-level operation state, and a high-level operation state with successively increasing massage intensity; the first battery 100 has a battery capacity of C1, and the second battery 200 has a battery capacity of C2.

[0103] The control method specifically includes the following steps: Control the first battery 100 and the second battery 200 to supply power to the reciprocating drive component 2 in one or a combination of simultaneous power supply, alternating power supply, etc. When the first battery 100 is not in a power-off state, the first battery 100 is charged; When the second battery 200 is not in a power supply state, the second battery 200 is charged.

[0104] The process of controlling the first battery 100 and the second battery 200 to supply power to the reciprocating drive component 2 in a manner that is simultaneous, alternating, or a combination thereof specifically includes the following steps: When the massage device is operating at a medium speed, the second battery 200 is prioritized for power supply. Simultaneously, the real-time power levels C11 of the first battery 100 and C21 of the second battery 200 are monitored. The charging threshold Y1 and downsizing threshold J1 for the first battery 100 are set, as are the charging threshold Y2 and power consumption threshold Z2 for the second battery 200. When C21 < Y2 (e.g., Y2 = 10% C2), the second battery 200 is stopped from supplying power, and the first battery 100 is used for power supply until C21 ≥ Z2 (e.g., Z2 = 80% C2), at which point the second battery 200 is switched to power supply. When only the first battery 100 is used, if C11 < J1 (e.g., J1 = 50% C1), the massage device is switched to a low speed operating state until C21 ≥ Z2 (Z2 = 80% C2), at which point the second battery 200 is switched to power supply, and the massage device is switched to a medium speed operating state.

[0105] When the massage device is operating at a high setting, the first battery 100 and the second battery 200 are simultaneously powered. At the same time, the real-time charge levels C11 of the first battery 100 and C21 of the second battery 200 are monitored. A charging threshold Y1 for the first battery 100, a charging threshold Y2, a power consumption threshold Z2, and a reduction charge level J2 for the second battery 200 are set. When C11 < Y1 (e.g., Y1 = 30% C1), power supply to the first battery 100 is stopped, and the first battery 100 is charged. When C21 < Y2 (e.g., Y2 = 10%C2), the second battery 200 is stopped from supplying power and is charged until C21 ≥ Z2 (e.g., Z2 = 80%C2), at which point the second battery 200 is switched to supply power. In addition, when the second battery 200 is supplying power, if C21 < J2 (e.g., J2 = 40%C2), the massage device is switched to the medium-level operation state until C21 ≥ J2 (e.g., J2 = 40%C2), at which point the silencer is switched to the high-level operation state.

[0106] When the massage device is operating at a low setting, the second battery 200 is prioritized for power supply. Simultaneously, the real-time power levels C11 of the first battery 100 and C21 of the second battery 200 are monitored. The charging threshold Y1 of the first battery 100, the charging threshold Y2 of the second battery 200, and the power consumption threshold Z2 are set. When C21 < Y2 (e.g., Y2 = 10% C2), the second battery 200 is stopped from supplying power, and the first battery 100 is used for power supply until C21 ≥ Z2 (e.g., Z2 = 80% C2), at which point the second battery 200 is switched to power supply. When C11 < Y1 (Y1 = 10% C1), the first battery 100 is stopped from supplying power, and the second battery 200 is used for power supply.

[0107] It is easy to understand that the second battery 200 is the main power supply battery, and the first battery 100 is the auxiliary power supply battery. During the operation of the massage device, the second battery 200 is used first for power supply. When the second battery 200 alone cannot meet the power requirements of the massage level or when the second battery 200 is charging, the first battery 100 is used to supply power so that the second battery 200 can be used again. In addition, when the first battery 100 or the second battery 200 alone is used for power supply, if the power is insufficient to support the corresponding power level, the massage level can be reduced or the device can be turned off.

[0108] Furthermore, to meet the requirement that the second battery 200 serves as the primary power supply battery, the battery capacity C2 of the second battery 200 is greater than the battery capacity C1 of the first battery 100. Preferably, the range of values ​​for the battery capacity C2 of the second battery 200 and the battery capacity C1 of the first battery 100 satisfies: 2 ≤ C2 / C1 ≤ 3. In addition, the value of C2 / C1 can also determine the values ​​of the previously mentioned reduced power level J1, power consumption threshold Z2, and reduced power level J2.

[0109] It is worth noting that the corresponding power reduction amount J1, power consumption threshold Z2, and power reduction amount J2 may be different for different levels.

[0110] Furthermore, this control method also includes the following steps: Monitor the real-time power level C11 of the first battery 100 and the real-time power level C21 of the second battery 200; Set the charging threshold Y1 and charging critical value X1 for the first battery 100, and set the charging threshold Y2 and the critical capacity value X2 that allows reverse charging for the second battery 200. When the fascia gun is not in operation, when C11 < Y1 (e.g., Y1 = 10% C1) and C21 ≥ X2 (e.g., X2 = 60% C2), the second battery 200 is controlled to charge the first battery 100 until C11 > X1 (e.g., X1 = 30% C1), then charging stops. When the fascia gun is in operation, if C11 < Y1 (e.g., Y1 = 10% C1) and C21 < Y2 (e.g., Y2 = 10% C2), the user is prompted to charge. If the user is not prompted to charge within a preset time period, the fascia gun is stopped.

[0111] Furthermore, the control circuit 300 also includes a display screen 306 and a control button 307, both of which are mounted on the handle part 4. The display screen 306 can be used to display the real-time power of the first battery 100 and the second battery 200, while the control button 307 can be used to switch the massage device's intensity level or control the massage device to stop.

[0112] It should be understood that users can control the massage device to charge, switch gears, or stop based on the real-time power levels of the first battery 100 and the second battery 200 displayed. Alternatively, users can set up a control board and directly use the built-in algorithm program on the control board to implement the above control methods. The algorithm is not an improvement point, so it will not be described in detail.

[0113] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
