DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0037] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0038] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0039] In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance. It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered as the scope of protection of the present utility model.

[0040] With reference to Figures 2 to 3 of the specification, the present invention provides a flexible rehabilitation device, which includes a telescopic structure 1 and a charging component 2. The telescopic structure 1 has a telescopic cavity 11, and a first opening is provided at one end of the telescopic cavity 11. The telescopic structure 1 is axially corrugated; the charging component 2 is connected to the telescopic cavity 11 through the first opening, and the charging component 2 is suitable for flushing or sucking fluid into the telescopic cavity 11, and driving the telescopic structure 1 to axially telescope and deform.

[0041] In this embodiment, the telescopic structure 1 is corrugated axially, and the charging component 2 can drive the telescopic structure 1 to axially telescopically deform faster and more sensitively. The telescopic structure 1 has a faster telescopic response and the hardness of the telescopic structure 1 after deformation is better, and the user experience is better.

[0042] Specifically, the telescopic structure 1 is axially corrugated, with troughs and peaks in the axial direction. The pressure-charging assembly 2 is adapted to inject fluid into the telescopic chamber 11. Under the action of the fluid, the telescopic structure 1 preferentially undergoes axial telescopic deformation, and the axial telescopic deformation response of the telescopic structure 1 is rapid. Simultaneously, the corrugated telescopic structure 1 has improved telescopic flexibility, enabling it to be driven and achieve large deformations with a smaller volume. The telescopic structure 1 has a shorter axial telescopic response and higher sensitivity. Furthermore, the corrugated telescopic structure 1 has a greater elongation ratio, enabling it to extend farther. Fluids include media such as gas and water, and the pressure-charging assembly 2 includes, but is not limited to, micro air pumps, micro water pumps, and the like, which are not further defined in this application.

[0043] Furthermore, referring to Figures 3 and 4 of the specification, the telescopic sleeve 3 is also included. The telescopic sleeve 3 is arranged on the outside of the telescopic structure 1. The telescopic structure 1 is also provided with a protrusion 12. The protrusion 12 extends along the axial direction of the telescopic structure 1 to the side away from the first opening. The protrusion 12 is provided with a placement groove connected to the telescopic cavity 11. The placement groove is suitable for placing a vibration module; the telescopic sleeve 3 is provided with a mounting groove 31 at a corresponding position of the protrusion 12. The protrusion 12 is suitable for abutting and mounting in the mounting groove 31, so that the vibration module can better transmit torque to the telescopic sleeve 3. The vibration module has the ability to convert its own state into undulating or turbulent; or the vibration module has the ability to convert the state of another object into undulating or turbulent. Exemplarily, the other object mentioned above can include the telescopic sleeve 3.

[0044] In this embodiment, the protrusion 12 of the telescopic structure 1 is suitable for being snap-fitted and placed in the mounting groove 31 of the telescopic sleeve 3, thereby enhancing the connection stability between the telescopic structure 1 and the telescopic sleeve 3. The vibration module in the protrusion 12 is more tightly connected to the telescopic sleeve 3, and the torque of the vibration module is transmitted more easily and quickly, so that the telescopic sleeve 3 vibrates along with the vibration module, providing a better user experience.

[0045] Specifically, the telescopic sleeve 3 is mounted on the outside of the telescopic structure 1. Made of skin-friendly silicone, the sleeve 3 effectively prevents the telescopic structure 1 on the flexible rehabilitation device from directly contacting the human body's muscles, which could cause discomfort. The sleeve 3 is also replaceable, effectively ensuring hygiene during long-term use and extending the service life of the flexible rehabilitation device. The cross-section of the protrusion 12 along the axial direction of the telescopic structure 1 is a D-shaped circle, and the mounting groove 31 of the telescopic sleeve 3 is also a D-shaped circle. This means that the notch of the mounting groove 31 is smaller than the maximum width of the protrusion 12. The width of the protrusion 12 first increases and then decreases along the axial direction of the telescopic structure 1. The protrusion 12 is adapted to be snap-fitted and fixed within the mounting groove 31. The telescopic sleeve 3 has a certain degree of elasticity. The protrusion 12 is placed in the mounting groove 31. The notch of the mounting groove 31 is first stretched open, and then the protrusion 12 is fixedly installed in the mounting groove 31. The outer wall of the protrusion 12 is tightly fitted and abutted against the inner wall of the mounting groove 31, increasing the contact area between the protrusion 12 and the mounting groove 31, so that the protrusion 12 is more firmly fixed in the mounting groove 31. At the same time, the mounting groove 31 also applies an axial limiting force to the protrusion 12 to prevent the protrusion 12 from accidentally separating axially from the mounting groove 31 during the telescopic structure 1. In addition, the vibration module is arranged at the end of the telescopic structure 1 away from the charging component 2, with greater torque and better vibration amplitude, so that it can contact the muscles to a greater extent, thereby producing a more effective stimulation effect. The vibration module promotes muscle contraction by generating a stimulation signal that can stimulate the muscles, thereby enabling the muscles to recover elasticity faster, thereby effectively enhancing the massage effect. The vibration module includes but is not limited to any one or more of a vibration motor, a current pulse patch, and a telescopic motor. The vibration motor, current pulse patch and telescopic motor can generate vibration stimulation signals, current stimulation signals and impact stimulation signals respectively, all of which can stimulate the muscles in the corresponding positions, thereby achieving the effect of promoting muscle contraction.

[0046] It is worth noting that the shapes of the protrusion 12 and the mounting groove 31 include, but are not limited to, the D-shaped circle of the present embodiment, and may also be other irregular shapes, such as a gourd, a wave, an ellipse, etc., so that the telescopic sleeve 3 and the telescopic structure 1 fit perfectly together and have an axial limiting force between the telescopic sleeve 3 and the telescopic structure 1, thereby preventing the telescopic sleeve 3 and the telescopic structure 1 from axially separating. In a modified embodiment, the vibration module can also be placed arbitrarily within the telescopic cavity 11 of the telescopic structure 1. When the vibration module is turned on, it will randomly impact within the telescopic cavity 11, causing the telescopic sleeve 3 to produce irregular and disordered movement, thereby providing the user with a more intense and comfortable user experience and achieving a better massage effect.

[0047] Furthermore, referring to Figure 5 of the specification, a limiting member 4 is provided between the telescopic sleeve 3 and the telescopic structure 1, and a second opening is provided at one end of the limiting member 4. The limiting member 4 is sleeved on the outside of the telescopic structure 1 through the second opening, and a through hole is provided on the side of the limiting member 4 away from the second opening. The protrusion 12 is suitable for passing through the through hole and reaching the mounting groove 31.

[0048] In this embodiment, the limiting member 4 is sleeved on the outside of the telescopic structure 1. The limiting member 4 can limit the radial telescopic deformation of the telescopic structure 1, so that the response speed of the axial telescopic deformation of the telescopic structure 1 is faster. At the same time, the limiting member 4 also ensures the radial hardness of the telescopic structure 1, bringing a better comfortable experience to the user.

[0049] Specifically, the limiting member 4 is primarily made of a material that is less elastic than the telescopic structure 1. The limiting member 4 is precisely fitted to the telescopic structure 1 through weaving, gluing, snapping, or sewing. This restrictive effect of the limiting member 4 effectively prevents radial expansion and deformation of the telescopic structure 1. The side of the limiting member 4 facing away from the second opening is a flat surface, perpendicular to the outer surface of the protrusion 12. This surface abuts the inner sidewall of the telescopic sleeve 3, facilitating the conversion of the radial expansion force of the telescopic structure 1 into an axial expansion force, thereby ensuring the telescopic length of the telescopic sleeve 3 while maintaining its hardness. It is worth noting that the limiting member 4 includes, but is not limited to, a structure disposed on the outside of the telescopic structure 1. The limiting member 4 may also be a restrictive structure such as a limiting rib, which is disposed along the circumferential direction of the telescopic structure 1 to control the radial expansion of the telescopic structure 1 without affecting the axial expansion and contraction of the telescopic structure 1.

[0050] In a modified embodiment, the limiting member 4 can also be a plurality of collar members arranged at intervals, which are arranged on the outside of the telescopic structure 1 and are relatively located at the troughs of the telescopic structure 1. The collar members can be made of a material with no elasticity or only weak elasticity, or can be made of a fiber, mesh, or other object with a longitudinal or transverse restriction. By providing the collar members, the connection structure between the telescopic structures 1 can be made more compact, thereby making the deformation of the entire telescopic structure 1 more flexible, so as to achieve a better massage effect. It is worth noting that the limiting member 4 can also control the bending deformation of the telescopic structure 1. As long as the limiting members 4 on both sides of the telescopic structure 1 are set to different elastic forces, the telescopic structure 1 bends toward the side with smaller elastic force during movement, so that the telescopic structure can move more flexibly, thereby effectively improving the massage effect and effectively improving the user comfort.

[0051] Furthermore, referring to Figures 1 and 5 to 8 of the specification, it also includes a shell 7 and an adapter 5, and a charging assembly 2 is provided in the shell 7; the two ends of the adapter 5 are detachably connected to the telescopic structure 1 and the shell 7 respectively, and a separation part 51 is provided on the cross section of the adapter 5, and the separation part 51 is axially provided with a through connecting piece 52, and the connecting piece 52 connects the telescopic cavity 11 and the charging assembly 2.

[0052] In this embodiment, the adapter 5 is detachably connected to the telescopic structure 1 and the housing 7 at both ends, making assembly and disassembly easy. Specifically, the telescopic structure 1, the limiting member 4, and the telescopic sleeve 3 resemble a nesting doll structure, one layer within another. The telescopic structure 1 and the limiting member 4 are fixed to the adapter 5 via a locking member 61, while the telescopic sleeve 3 is independently detachably fixed to the adapter 5. More specifically, the telescopic structure 1 is provided with a fixing portion 13 at one end having a first opening. The fixing portion 13 has a fixing groove 130. The adapter 5 is provided with a locking groove 53 corresponding to the fixing groove 130 on the outer side of the side adjacent to the telescopic structure 1. The limiting member 4 and the locking member 61 are also sleeved on the outer side of the telescopic structure 1. The locking member 61 locks the limiting member 4 and the telescopic structure 1 into the locking groove 53 of the adapter 5. The separating portion 51 of the adapter 5 separates the telescopic chamber 11 from the charging assembly 2. The output end of the charging assembly 2 is connected to the telescopic chamber 11 via a connecting member 52. It is worth noting that the locking member 61 is a commonly used locking structure, such as a rolled belt, a binding belt, a tightening belt, etc. Moreover, the telescopic structure 1 and the limiting member 4 can also be braided, bonded, snapped, or sewn together in other ways, which are not described in detail in this application. At the same time, the bottom of the telescopic sleeve 3 abuts the bottom of the adapter 5, so that the bottom of the telescopic sleeve 3 wraps around the bottom of the adapter 5, and the assembly 54 is relatively located outside the telescopic sleeve 3, that is, the bottom of the telescopic sleeve 3 is clamped between the adapter 5 and the assembly 54, so that the telescopic sleeve 3 is firmly fixed to the adapter 5, preventing the telescopic sleeve 3 from accidentally detaching from the adapter 5 during the telescopic structure 1 extension and contraction process, resulting in a very poor user experience.

[0053] Furthermore, the outer side of the locking member 61 is sleeved on the locking sleeve 6 , and the inner side of the locking sleeve 6 is provided with a receiving groove 60 for receiving the head of the locking member 61 .

[0054] In this embodiment, a locking sleeve 6 is provided on the outside of the locking member 61. The receiving groove 60 on the inside of the locking sleeve 6 is suitable for accommodating the head of the locking member 61, ensuring the smoothness of the outside of the telescopic structure 1 and preventing the outer surface of the telescopic sleeve 3 from denting. Specifically, the locking member 61 is not large enough to fill the entire space of the fixing groove 130, resulting in a loose fit between the telescopic sleeve 3 and the telescopic structure 1 at the fixing groove 130. This can easily cause the telescopic sleeve 3 to fail to respond to the telescopic deformation of the telescopic structure 1 in a timely manner, resulting in a longer time required for the telescopic sleeve 3 to extend and retract. The telescopic sleeve 3 is even prone to denting inward at the fixing groove 130, making the overall feel of the telescopic sleeve 3 uncomfortable and affecting the user experience. A locking sleeve 6 is provided on the outside of the locking member 61. The locking sleeve 6 fills the fixing groove 130, making the outer edge of the locking sleeve 6 relatively flush with the outer edge of the limiting member 4. The telescopic sleeve 3 fully contacts the locking sleeve 6 and the limiting member 4, ensuring a closer contact between the telescopic structure 1 and the telescopic sleeve 3. This prevents the telescopic sleeve 3 from being insufficiently rigid or dented in the locked position, making the outer surface of the telescopic sleeve 3 smoother and more comfortable for the user. Furthermore, to further eliminate the potential risk of unevenness or unevenness caused by the head of the locking member 61, a receiving groove 60 is provided on the inside of the locking sleeve 6 to accommodate the head of the locking member 61. The head of the locking member 61 is placed in the receiving groove 60 inside the locking sleeve 6 without affecting the overall outer edge of the locking sleeve 6. Furthermore, the abutment between the head of the locking member 61 and the inner wall of the receiving groove 60 of the locking sleeve 6 further strengthens the connection between the locking member 61 and the locking sleeve 6, preventing the locking sleeve 6 from detaching from the locking member 61 or accidental displacement of the locking sleeve 6, which could lead to unpredictable consequences. It is worth noting that, due to the variety and structure of locking member 61, the above embodiment focuses on a locking member 61 with a locking head, such as a rolled strip. In another embodiment, locking member 61 can also be a smoothly disposed circular band, etc. This avoids the disadvantage of a protruding head of locking member 61 and eliminates the need for a receiving groove 60 inside locking sleeve 6 to accommodate the head of locking member 61. Therefore, according to the specific structure of locking member 61, those skilled in the art may make other simple modifications or adaptive changes to locking sleeve 6, which are also within the scope of protection of this application.

[0055] It is worth noting that the cross-section of the adapter 5 is not further limited in this application. The adapter 5 can be circular, consistent with the cross-section of the fixing portion 13 of the telescopic structure 1; in another embodiment, the end of the adapter 5 close to the telescopic structure 1 can also be set to be non-circular, that is, one side of the adapter 5 is flat, and the adapter 5 is D-shaped as a whole, which can increase the locking strength between the adapter 5 and the telescopic structure 1, prevent the locking member 61 from rotating arbitrarily, and also reserve further space for the head of the locking member 61.

[0056] Furthermore, referring to Figure 7 of the specification, an assembly part 54 is provided at the bottom of the adapter 5, and a first locking structure 541 is provided on the assembly part 54. The shell 7 is also provided with a sliding groove 71 suitable for the sliding of the first locking structure 541, and a second locking structure 72 is provided in the sliding groove 71. The second locking structure 72 is suitable for abutting and fixing with the first locking structure 541.

[0057] In this embodiment, the adapter 5 is assembled to the housing 7 via an assembly 54, making installation simple and convenient. Specifically, the assembly 54 is ultrasonically welded to the bottom of the adapter 5. Both the adapter 5 and the assembly 54 are axially connected by a first extension and a second extension. The connecting piece 52 is press-fitted between the first and second extensions. The assembly 54 is removably mounted to the housing 7. An assembly groove is provided on the top of the housing 7, and a slide groove 71 is provided on the inner side wall of the assembly groove. The slide groove 71 includes an axial section and a circumferential section. The second locking structure 72 is provided on the side of the circumferential section close to the axial section. First locking structures 541 are provided at intervals in the circumference of the assembly 54. The first locking structures 541 slide along the axial section of the slide groove 71. When the first locking structure 541 reaches the end of the axial section, the assembly 54 is rotated again, so that the first locking structure 541 on the assembly 54 enters the circumferential section and passes through the second locking structure 72. Then, the first locking structure 541 abuts against the second locking structure 72, so that the assembly 54 is fixedly installed in the circumferential section of the slide groove 71. It is worth noting that other locking structures can also be provided on the adapter 5, such as screws, limit columns, electric limit rods, etc., which are all easily conceivable by those skilled in the art and are all within the scope of protection of this application.

[0058] Furthermore, referring to Figures 4 and 6 of the specification, a telescopic sleeve 3 is further provided on the outside of the telescopic structure 1. A plurality of clipping portions 55 are also spaced apart on the end of the adapter 5 away from the locking groove 53. A plurality of clipping grooves 32 matching the clipping portions 55 are further provided on the inside of the telescopic sleeve 3, so that the telescopic sleeve 3 is sleeved and fixed on the outside of the adapter 5. In this embodiment, the telescopic sleeve 3 is sleeved on the adapter 5 so that the clipping portions 55 are snap-fitted and installed in the clipping grooves 32. The assembly stability of the telescopic sleeve 3 and the adapter 5 is improved, the assembly is also simpler, and subsequent disassembly and assembly are convenient. The telescopic sleeve 3 has a certain degree of elasticity. When installing the telescopic sleeve 3, it is only necessary to expand the side of the telescopic sleeve 3 close to the first opening and sleeve it on the outside of the adapter 5 so that the clipping portions 55 of the adapter 5 are just snap-fitted and installed in the clipping grooves 32 on the inside of the telescopic sleeve 3, which can effectively prevent the telescopic sleeve 3 from accidentally detaching.

[0059] Furthermore, referring to FIG7 and FIG8 of the specification, the adapter 5 is further provided with a plurality of first conducting pins 56 , which axially penetrate the adapter 5 and are suitable for connecting to the vibration module in the telescopic structure 1 .

[0060] In this embodiment, the first conductive pin 56 axially passes through the separation portion 51 of the adapter 5. The two ends of the first conductive pin 56 are respectively connected to the vibration module and other components inside the housing 7, which facilitates conductive connection of the vibration module inside the telescopic structure 1 while ensuring the airtightness of the telescopic structure 1. Specifically, a third conductive pin 73 is provided in the assembly groove of the housing 7. The third conductive pin 73 is connected to the battery and circuit board inside the housing 7. After the adapter 5 and the housing 7 are installed, the third conductive pin 73 is suitable for conductive connection with the first conductive pin 56; the first conductive pin 56 passes through the center of the adapter 5 and the assembly 54. A first connector is provided inside the telescopic structure 1. The first connector connects the vibration module and the first conductive pin 56. The first connector needs to leave a reserved length for the telescopic structure 1 to extend and retract to prevent the first connector from separating from the first conductive pin 56 after the telescopic structure 1 is extended and retracted.

[0061] Furthermore, the adapter 5 is also provided with a plurality of second conducting pins 57, which axially penetrate the adapter 5 and are suitable for connecting to the heating module. The second conducting pins 57 are relatively close to the outer edge of the adapter 5, that is, the second conducting pins 57 are relatively located radially outside the telescopic structure 1. The clamping portion 55 of the adapter 5 also leaves a gap for the second conducting pins 57, and this gap also facilitates the removal of the telescopic sleeve 3. A fourth conducting pin 74 is provided on the shell 7, and the fourth conducting pin 74 is also connected to the battery and circuit board inside the shell 7. After the adapter 5 and the shell 7 are installed, the fourth conducting pin 74 is suitable for conducting and connecting with the second conducting pin 57. In this embodiment, after the heating module is turned on, the flexible rehabilitation device is heated so that the temperature of the flexible rehabilitation device rises to a certain level, thereby effectively avoiding the situation where the user feels uncomfortable due to the low temperature during use, thereby bringing a more comfortable experience to the user. The heating module can be arranged between the telescopic sleeve 3 and the limiting member 4, or between the limiting member 4 and the telescopic structure 1, or even embedded in the telescopic sleeve 3, or the heating module heats the fluid in the telescopic structure 1, or the heating module is spirally sleeved on the outside of the limiting member 4 or the telescopic structure 1. These are all variant embodiments of this embodiment. This application does not further limit the installation position and specific heating structure of the heating module. As long as it is connected to the battery and circuit board inside the shell 7 through the second conductive pin 57, this is within the scope of protection of this application.
