Description

Technical Field

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

[0002] A fascia gun, also known as a "muscle fascia relaxation massage gun," is a portable soft tissue rehabilitation tool that uses high-frequency impact vibrations to relax muscles and fascia. It utilizes an internal high-speed motor to drive the massage head, producing deep percussion. Its main functions include relieving muscle tension after exercise, promoting blood circulation, accelerating lactic acid metabolism, and helping users warm up quickly before exercise, activate target muscle groups during exercise, and restore muscle elasticity after exercise. Due to its effectiveness in improving muscle soreness and fatigue, this type of device is widely used in sports rehabilitation and daily health care.

[0003] However, existing fascia gun products lack real-time pressure detection. When massaging muscles in different areas, such as the shoulders, neck, and lower back, the tolerance of different areas varies greatly, making it difficult for users to accurately control the pressure based on subjective feelings. Utility Model Content

[0004] The main purpose of this invention is to propose a fascia gun that enables real-time detection of the massage intensity of the fascia gun.

[0005] To achieve the above objectives, the fascia gun proposed in this utility model includes: The outer shell has a flexible structure; A driving structure is fixed to the elastic structure; A massage head is disposed at the output end of the drive structure, the drive structure being used to drive the massage head to reciprocate and extend, the reciprocating and extending direction of the massage head being perpendicular to the axial direction of the drive shaft of the drive structure; and A force detection element is disposed on the elastic structure; When the driving structure drives the massage head to extend and act on the human body, the massage head receives a reaction force from the human body. This reaction force is transmitted to the elastic structure via the driving structure and causes deformation of the elastic structure. The force detection element detects the magnitude of the massage force exerted by the massage head on the human body in real time by detecting the deformation of the elastic structure.

[0006] In one embodiment, the elastic structure is formed on the outer shell.

[0007] In one embodiment, the outer shell includes a shell body and an elastic portion connected to the shell body, wherein a deformation groove is provided between the elastic portion and the shell body, and the elastic structure is configured as the elastic portion.

[0008] In one embodiment, the shell body and the elastic portion are connected by bridging portions, and multiple bridging portions are provided, with deformation grooves provided between adjacent bridging portions.

[0009] In one embodiment, one of the bridging portions is provided with a mounting position for mounting the force detection element. Of all the bridging portions, the bridging portion with the mounting position has the largest width; and / or, The length of the deformation grooves on both sides of the mounting position is greater than the length of the mounting position, and the mounting position is located away from the shell body.

[0010] In one embodiment, the elastic portion is provided with a plurality of interconnected connection positions arranged at intervals, the connection positions being used for fixing the drive structure, and the connection positions being staggered from the bridging portion.

[0011] In one embodiment, along the direction of movement of the massage head, the force detection element is disposed on at least one of the opposite sides of the elastic structure.

[0012] In one embodiment, the force sensing element is configured as a strain gauge.

[0013] In one embodiment, the fascia gun is further provided with a position detection element and a controller. The controller is electrically connected to the position detection element and the force detection element respectively. The position detection element is used to send position information to the controller when the massage head is at its maximum extension stroke. After receiving the position information, the controller controls the force detection element to detect the massage force.

[0014] In one embodiment, the position detection element is configured as a Hall sensor mounted on the housing, and the drive structure includes a drive motor, an eccentric wheel, and a connecting rod connected in sequence. The connecting rod is connected to the massage head in a driving connection. The eccentric wheel is provided with a sensing magnet. When the massage head is at its maximum extension stroke, the sensing magnet corresponds to the detection unit of the Hall sensor.

[0015] This invention provides a fascia gun with a housing, a drive structure, a massage head, and a force detection component. The housing has an elastic structure, one end of the drive structure is fixed to the elastic structure, and the other end is connected to the massage head to drive its reciprocating extension and retraction. The force detection component is located on the elastic structure. When the drive structure extends the massage head to act on the human body, the massage head receives a reaction force from the human body. This reaction force is transmitted to the elastic structure through the drive structure, causing deformation of the elastic structure. The force detection component detects the deformation of the elastic structure in real time to determine the magnitude of the massage force exerted by the massage head on the human body. Thus, on the one hand, by incorporating an elastic structure on the housing and detecting its deformation in real time, the magnitude of the massage force exerted by the massage head on the human body can be detected in real time. This allows for adjustment of the massage force by adjusting the drive force of the drive structure, thereby improving the comfort of using the fascia gun. On the other hand, placing the elastic structure on the housing avoids the possibility that deformation of the elastic structure might be caused by the extension and retraction of the massage head, ensuring the accuracy of the massage force detection results.

[0023] A fascia gun, also known as a "muscle fascia relaxation massage gun," is a portable soft tissue rehabilitation tool that uses high-frequency impact vibrations to relax muscles and fascia. It utilizes an internal high-speed motor to drive the massage head, producing deep percussion. Its main functions include relieving muscle tension after exercise, promoting blood circulation, accelerating lactic acid metabolism, and helping users warm up quickly before exercise, activate target muscle groups during exercise, and restore muscle elasticity after exercise. Due to its effectiveness in improving muscle soreness and fatigue, this type of device is widely used in sports rehabilitation and daily health care.

[0024] However, existing fascia gun products lack real-time pressure detection. When massaging muscles in different areas, such as the shoulders, neck, and back, the tolerance of different areas varies greatly. Users find it difficult to accurately control the pressure based on subjective feelings. This may result in situations where excessive pressure causes back muscle strain and subcutaneous bruising, while insufficient pressure fails to achieve an effective relaxation effect.

[0025] This utility model proposes a fascia gun.

[0026] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the fascia gun includes a housing 100, a drive structure 300, a massage head 400, and a force detection component 500. The housing 100 is provided with an elastic structure 200 (such as...). Figure 3 As shown, the drive structure 300 is fixed to the elastic structure 200, and the massage head 400 is located at the output end of the drive structure 300. The drive structure 300 is used to drive the massage head 400 to reciprocate and extend, and the direction of reciprocating extension and retraction of the massage head 400 is perpendicular to the axial direction of the drive shaft of the drive structure 300. The force detection element 500 is located on the elastic structure 200. When the drive structure 300 drives the massage head 400 to extend and act on the human body, the massage head 400 receives a reaction force from the human body. This reaction force is transmitted to the elastic structure 200 through the drive structure 300 and causes the elastic structure 200 to deform. The force detection element 500 detects the deformation of the elastic structure 200 in real time to detect the magnitude of the massage force of the massage head 400 acting on the human body in real time.

[0027] Specifically, such as Figure 3 As shown, the outer shell 100 is provided with an elastic structure 200, which has a certain deformation capacity. A drive structure 300 is fixed to the elastic structure 200 of the outer shell 100, and the output end of the drive structure 300 is connected to the massage head 400, causing the massage head 400 to reciprocate under the drive of the drive structure 300, thereby achieving massage of the human body. When the driving force of the drive structure 300 is different, the massage intensity of the massage head 400 on the human body is also different. In order to detect the massage intensity received by the human body in real time, the fascia gun of this invention is provided with a force detection component 500.

[0028] Understandable, such as Figures 1 to 3As shown, the elastic structure 200, driving structure 300, and massage head 400 are connected in sequence. When the massage head 400 comes into contact with the human body, it receives a reaction force from the body. This reaction force is transmitted to the elastic structure 200 through the driving structure 300, causing a slight deformation of the elastic structure 200 under this reaction force. Simultaneously, a force detection element 500 is installed on the elastic structure 200, which can detect the deformation of the elastic structure 200 in real time. It can be understood that when the deformation of the elastic structure 200 is large, the massage force received by the human body is large; when the deformation of the elastic structure 200 is small, the massage force received by the human body is small. The force detection element 500 can detect the deformation of the elastic structure 200. Therefore, the magnitude of the massage force received by the human body can be determined based on the detected deformation of the elastic structure 200, thus achieving real-time detection of the massage force. Furthermore, the massage force can be adjusted as needed by adjusting the driving force of the driving structure 300.

[0029] Understandably, when using a fascia gun, the drive structure 300 drives the massage head 400 to reciprocate, while the outer shell 100 remains stationary during this process. By placing the elastic structure 200 on the outer shell 100, the possibility that deformation of the elastic structure 200 might be caused by the reciprocating motion of the massage head 400 is avoided, ensuring the accuracy of the massage force detection results. Furthermore, the outer shell 100 has one end near the massage head 400, one end away from the massage head 400, and a middle portion between the two ends. In one embodiment, the elastic structure 200 is located at the end of the outer shell 100 away from the massage head 400. This further reduces the possibility that deformation of the elastic structure 200 might be caused by the reciprocating motion of the massage head 400, further improving the accuracy of the massage force detection.

[0030] In this invention, the direction of reciprocating extension and retraction of the massage head 400 is perpendicular to the axial direction of the drive shaft of the drive structure 300. Please refer to [link / reference]. Figure 1 and Figure 2 The drive structure 300 includes a drive motor 310, an eccentric wheel 320, and a connecting rod 330. The motor shaft of the drive motor 310 is also the drive shaft of the drive structure 300. The eccentric wheel 320 is sleeved on the drive shaft of the drive motor 310. One end of the connecting rod 330 is connected to the eccentric wheel 320, and the other end is connected to the massage head 400. The drive shaft of the drive motor 310 and the connecting rod 330 are approximately L-shaped. The extension direction of the connecting rod 330 is consistent with the extension and retraction direction of the massage head 400, thus making the axial direction of the drive shaft of the drive structure 300 perpendicular to the reciprocating extension and retraction direction of the massage head 400.

[0031] The technical solution of this utility model involves setting a shell 100, a drive structure 300, a massage head 400, and a force detection component 500 in a fascia gun. The shell 100 is provided with an elastic structure 200. One end of the drive structure 300 is fixed to the elastic structure 200, and the other end is driven to connect to the massage head 400 to drive the massage head 400 to reciprocate and extend. The force detection component 500 is provided in the elastic structure 200. When the drive structure 300 drives the massage head 400 to extend and act on the human body, the massage head 400 receives a reaction force from the human body. This reaction force is transmitted to the elastic structure 200 through the drive structure 300, causing the elastic structure 200 to deform. The force detection component 500 detects the deformation of the elastic structure 200 in real time to detect the magnitude of the massage force exerted by the massage head 400 on the human body. Thus, on the one hand, by providing an elastic structure 200 on the outer shell 100 and detecting the deformation of the elastic structure 200 in real time through the force detection component 500, the magnitude of the massage force exerted by the massage head 400 on the human body can be detected in real time. Furthermore, the massage force can be adjusted by regulating the driving force of the drive structure 300, thereby improving the comfort of using the fascia gun. On the other hand, by placing the elastic structure 200 on the outer shell 100, the possibility that the deformation of the elastic structure 200 might be caused by the extension and retraction of the massage head 400 is avoided, ensuring the accuracy of the massage force detection results.

[0032] Please see Figure 3 In this embodiment of the invention, the elastic structure 200 is formed on the outer shell 100. That is, the elastic structure 200 and the outer shell 100 are integrally formed structures and are manufactured as a whole. Compared with the arrangement where the elastic structure 200 and the outer shell 100 are connected by an intermediate component, this arrangement is beneficial for simplifying the structure and processing of the elastic structure 200 and the outer shell 100.

[0033] Please see Figure 3 In an embodiment of the present invention, the outer shell 100 includes a shell body 110 and an elastic portion 120 connected to the shell body 110. A deformation groove 130 is provided between the elastic portion 120 and the shell body 110. The elastic structure 200 is configured as the elastic portion 120.

[0034] Specifically, in the solution shown in the figures of this utility model, the outer shell 100 includes a shell body 110 and an elastic portion 120 connected together, wherein the elastic structure 200 is also the elastic portion 120, and a deformation groove 130 is provided between the shell body 110 and the elastic portion 120. It is understood that the deformation groove 130 provides deformation space for the elastic portion 120, which is beneficial to the deformation of the elastic portion 120. It is also understood that the elastic portion 120 needs to be made of a deformable material. In one embodiment, the elastic portion 120 is made of aluminum alloy, which can balance high strength and good elasticity, thus improving the accuracy of massage force detection.

[0035] Please see Figure 3 In an embodiment of this utility model, the shell body 110 and the elastic portion 120 are connected by a bridging portion 140. Multiple bridging portions 140 are provided, and deformation grooves 130 are provided between adjacent bridging portions 140.

[0036] Specifically, the shell body 110 and the elastic portion 120 are connected by bridging portions 140, making the shell body 110 and the elastic portion 120 an integral structure. Multiple bridging portions 140 are provided, spaced apart, and deformation grooves 130 are provided between adjacent bridging portions 140. That is, in the solution shown in the figures of this utility model, the shell body 110 and the elastic portion 120 are connected at multiple points. Compared to a single-point connection, this makes it easier for the elastic portion 120 to receive the reaction force from the massage head 400 and to deform more easily, thus making the detection of massage force more accurate. It also improves the stability and reliability of the connection between the elastic portion 120 and the shell body 110, and facilitates the deformation recovery of the elastic portion 120. In the solution shown in the figures of this utility model, the elastic portion 120 and the shell body 110 are connected by three bridging portions 140, which are evenly spaced apart. The number of bridging portions 140 is not limited here.

[0037] Please see Figure 3 In an embodiment of this utility model, a bridging portion 140 is provided with a mounting position 141 for mounting the force detection component 500. Among all the bridging portions 140, the bridging portion 140 with the mounting position 141 has the largest width; and / or, the length of the deformation grooves 130 on opposite sides of the mounting position 141 is greater than the length of the mounting position 141, and the mounting position 141 is located away from the shell body 110.

[0038] Specifically, in the solution shown in the figures of this utility model, the force detection element 500 is mounted on a bridging portion 140, thus facilitating and directly detecting the deformation of the elastic portion 120. It is understood that the force detection element 500 has a certain size, and the bridging portion 140 needs to have a certain width to ensure the mounting area of ​​the force detection element 500. The other bridging portions 140 without force detection elements 500 only serve to connect the elastic portion 120 and the shell body 110. To ensure good elasticity of the elastic portion 120, the other bridging portions 140 do not need to have a large width. Therefore, the width of the bridging portion 140 with the force detection element 500 is set to be greater than the width of the other bridging portions 140 without the force detection element 500. In this way, both the installation requirements of the force detection element 500 and the elastic capacity of the elastic portion 120 are satisfied.

[0039] In one embodiment, the length of the deformation grooves 130 on opposite sides of the mounting position 141 is greater than the length of the mounting position 141. This facilitates the transmission of deformation of the elastic portion 120 to the mounting position 141, allowing it to be detected by the force detection element 500, further improving the accuracy of massage force detection. Furthermore, the mounting position 141 is positioned away from the housing body 110, allowing the force detection element 500 to be closer to the elastic portion 120. This enables the force detection element 500 to detect the deformation of the elastic portion 120 more directly, promptly, and quickly, avoiding loss of deformation of the elastic portion 120 over a longer transmission path. This improves the accuracy of deformation detection by the force detection element 500, and consequently, improves the accuracy of massage force detection by the fascia gun.

[0040] Please see Figure 3 In an embodiment of this utility model, the elastic part 120 is provided with a plurality of interconnecting positions 121 arranged at intervals. The interconnecting positions 121 are used for fixing the drive structure 300. The interconnecting positions 121 are staggered with the bridging part 140.

[0041] Specifically, the drive structure 300 is fixed to the elastic portion 120. The elastic portion 120 has multiple spaced-apart connection positions 121, and the drive structure 300 has multiple fixing positions, each corresponding to and matching one-to-one with a connection position 121. The connection positions 121 and the bridging portion 140 are staggered. Compared to placing the connection positions 121 on the bridging portion 140, this arrangement is more conducive to the drive structure 300 accurately transmitting the reaction force from the massage head 400 to the elastic portion 120, thus reducing losses during transmission.

[0042] In the embodiment shown in the figures of this utility model, the connecting position 121 is configured as a connecting hole, the driving structure 300 is configured as a driving motor 310, and the motor housing of the driving motor 310 is provided with a fixing hole. The connecting hole and the fixing hole correspond one-to-one, and the bolt passes through the connecting hole and the fixing hole, thereby fixing the driving structure 300 and the elastic structure 200 together. It can be understood that, to achieve the connection between the driving structure 300 and the massage head 400, the elastic part 120 is provided with a clearance hole for the motor shaft of the driving motor 310 to pass through. There is a gap between the motor shaft and the clearance hole to prevent the elastic part 120 from interfering with the rotation of the motor shaft. The clearance hole is a circular hole, and multiple bridging parts 140 are evenly spaced along the circumference of the clearance hole, as are multiple connecting positions 121.

[0043] Please see Figure 1 and Figure 3 In an embodiment of this utility model, along the movement direction of the massage head 400, the force detection element 500 is disposed on at least one of the opposite sides of the elastic structure 200.

[0044] Understandably, when the massage head 400 is working, it will reciprocate and extend under the drive of the drive structure 300. Correspondingly, the reaction force from the human body that the massage head 400 receives is in the same direction as the retraction of the massage head 400. When this reaction force is transmitted to the elastic structure 200 through the drive structure 300, the deformation of the elastic structure 200 is mainly concentrated in the extension and retraction direction of the massage head 400. Thus, placing the force detection element 500 on at least one of the opposite sides of the elastic structure 200 along the extension and retraction direction of the massage head 400 further improves the accuracy of the detection.

[0045] In one embodiment, two force detection elements 500 are provided, located on opposite sides of the elastic structure 200 along the movement direction of the massage head 400. When calculating the massage force, the average of the detection results of the two force detection elements 500 can be used.

[0046] In one embodiment, a force detection element 500 is provided along the movement direction of the massage head 400, and is located on one of the opposite sides of the elastic structure 200. In the embodiment shown in the figures of this utility model, the force detection element 500 is located on the side of the elastic structure 200 away from the massage head 400, thus keeping the force detection element 500 away from the massage head 400 and further avoiding the influence of the movement of the massage head 400 on the detection results.

[0047] In embodiments of this invention, the force detection element 500 is configured as a strain gauge. Specifically, in this invention, commercially available strain gauges can be used, thus avoiding the need for custom-made strain gauges and reducing costs. In one embodiment, a full-bridge metal foil strain gauge is used. The strain gauge is fixed to the bridging portion 140 by means of bonding or other methods.

[0048] Of course, in other embodiments, the force detection element 500 can also be a linear variable differential transformer, a capacitive displacement sensor, etc., and there are no limitations here.

[0049] Please see Figure 1 In an embodiment of this utility model, the fascia gun is further provided with a position detection component 600 and a controller. The controller is electrically connected to the position detection component 600 and the force detection component 500 respectively. The position detection component 600 is used to send position information to the controller when the massage head 400 is at its maximum extension stroke. After receiving the position information, the controller controls the force detection component 500 to detect the massage force.

[0050] Specifically, the fascia gun also includes a controller and a position detection component 600. The controller is electrically connected to the position detection component 600 and the force detection component 500, respectively. This means the controller can receive signals from the position detection component 600 and the force detection component 500, and can control their operation. Understandably, when the fascia gun is in use, the massage head 400 reciprocates under the drive of the drive structure 300. The massage force of the fascia gun refers to the force exerted by the massage head 400 on the human body when it is at its maximum extension. That is, when detecting the massage force exerted by the massage head 400 on the human body, the deformation of the elastic structure 200 when the massage head 400 is at its maximum extension needs to be measured.

[0051] Therefore, this invention includes a position detection component 600. When the massage head 400 is at its maximum extension stroke, the position detection component 600 sends position information to the controller. Upon receiving this position information, the controller controls the force detection component 500 to detect the deformation of the elastic structure 200, thereby detecting the massage force. In this way, by incorporating the position detection component 600, this invention solves the problem of existing fascia guns lacking a position detection component 600, resulting in the inability to detect whether the massage head 400 is in contact with the human body and the collection of excessive random invalid data, significantly improving detection accuracy. When the fascia gun is mounted on a robotic arm, this greatly increases the proportion of effective data, reduces data processing workload, and allows for more timely motion compensation commands to the robotic arm, effectively improving the fit accuracy during massage.

[0052] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the position detection component 600 is configured as a Hall sensor 610 installed on the housing 100. The drive structure 300 includes a drive motor 310, an eccentric wheel 320 and a connecting rod 330 connected in sequence. The connecting rod 330 is connected to the massage head 400 in a transmission manner. The eccentric wheel 320 is provided with a sensing magnet 321. When the massage head 400 is at its maximum extension stroke, the sensing magnet 321 corresponds to the detection unit of the Hall sensor 610.

[0053] Specifically, in one embodiment, the position detection element 600 is configured as a Hall sensor 610. The Hall sensor 610 is mounted on the housing 100 via a mounting bracket, and the detection unit of the Hall sensor 610 is located above the elastic structure 200. The drive structure 300 includes a drive motor 310, an eccentric wheel 320, and a connecting rod 330. The motor housing of the drive motor 310 is mounted on the connection position 121 of the elastic structure 200. The motor shaft of the drive motor 310 passes through the clearance hole on the elastic structure 200 and is fitted with the eccentric wheel 320. The output shaft of the eccentric wheel 320 is fitted with the connecting rod 330, and the other end of the connecting rod 330 is connected to the massage head 400. In this way, the eccentric wheel 320 converts the circular rotational motion into linear reciprocating motion. An induction magnet 321 is mounted on the eccentric wheel 320, and the detection unit of the Hall sensor 610 is located above the induction magnet 321, meaning that there is no contact between the two. As the drive motor 310 rotates, the eccentric wheel 320 rotates accordingly, and the induction magnet 321 on the eccentric wheel 320 also rotates. When the induction magnet 321 is exactly opposite to the detection unit of the Hall sensor 610, that is, when the projection of the detection unit falls on the induction magnet 321, the massage head 400 is at its maximum extension stroke. At this time, the Hall sensor 610 sends position information to the controller. After receiving the position information, the controller controls the force detection element 500 to start detecting the deformation of the deformable structure, thereby realizing the detection of the massage force.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
