Description

Technical Field

[0001] This utility model relates to the field of massage device technology, specifically to a fascia gun. Background Technology

[0002] A fascia gun is a portable tool that uses high-frequency vibration to relax muscles and fascia. It contains a high-speed motor that drives the massage head to vibrate through a transmission mechanism.

[0003] In related technologies, high-speed motors vibrate strongly, and since the motor is fixed inside the housing by a support structure, the motor and the housing resonate when the motor is working, causing the housing to vibrate significantly. This affects the operator's gripping ability and also leads to excessive noise, impacting the user experience and product performance. Utility Model Content

[0004] In view of this, the present invention provides a fascia gun to solve the problem that the strong vibration of the high-speed motor causes the shell to vibrate greatly and the noise to be loud, which affects the user experience and product performance.

[0005] This utility model provides a fascia gun, comprising: a housing; a motor disposed inside the housing; a support having a support plate and a wing plate connected to the support plate; the support plate is fixed to the motor, the wing plate is spaced apart from and opposite to at least a portion of the housing, and a mounting hole is provided through the wing plate; a fixing post having a first end fixed to the inner wall of the housing and a second end movably passing through the mounting hole; a first elastic member disposed inside the housing, with both ends abutting against the wing plate and the opposite wall surface of the housing, the wing plate being adapted to move along the axial direction of the fixing post in the direction of compressing the elastic member; and a second elastic member sleeved on the fixing post and sandwiched between the fixing post and the inner wall of the mounting hole, the second elastic member being limitedly connected to the wing plate.

[0006] Beneficial effects: By incorporating a first elastic element located inside the housing with its two ends abutting against the support and the opposing wall of the housing, when the motor vibrates or displaces, the vibration or displacement is transmitted to the first elastic element via the support, causing the first elastic element to undergo elastic deformation to absorb vibration energy and provide cushioning. Thus, during motor operation, the vibration transmitted to the housing is effectively reduced through the shock absorption effect of the first elastic element, thereby reducing product operating noise and improving user experience. Simultaneously, when the fascia gun is subjected to external impact or drop, the first elastic element can provide cushioning, preventing the motor assembly from directly bearing the impact, thereby effectively protecting the connection structure between the motor and the housing, reducing the risk of damage, and extending the normal service life of the product.

[0007] In one alternative embodiment, the first elastic element is disposed around the periphery of the fixed post.

[0008] Beneficial effects: The fixed column is used to connect the wing plate and the shell. By circling the first elastic element around its periphery, it serves two purposes: firstly, it limits the first elastic element, preventing it from shifting or falling off when subjected to force, thus ensuring that the first elastic element is stably positioned at the motor; secondly, the end of the first elastic element abuts against the wing plate, and the circumferential arrangement increases the contact area between it and the bracket and the shell, so that the first elastic element is subjected to force evenly as a whole when subjected to vibration or impact, thereby improving the buffering effect.

[0009] In one alternative embodiment, the fascia gun further includes a fastener connected to the fixing post and having an end plate protruding radially from the fixing post, the end plate abutting against the side of the elastic member opposite to the first elastic member.

[0010] Beneficial effects: By setting a second elastic element, which is clamped between the inner wall of the mounting hole and the outer wall of the fixed column and connected to the wing plate for limiting, the motor bracket is prevented from directly contacting the fixed column. When the motor is working, hard collisions between the fixed column and the motor bracket are prevented, reducing damage and noise. The fixed column, with the cooperation of the second elastic element, the mounting hole and the fasteners, achieves a flexible connection with the bracket, further improving the stability and shock absorption effect of the overall structure.

[0011] In one alternative embodiment, the fascia gun further includes a limiting sleeve that surrounds the periphery of the elastic member and is fixed to the inner wall of the housing.

[0012] Beneficial effects: The limiting sleeve is fitted on the outer periphery of the first elastic element, which can effectively limit the deformation range of the first elastic element during compression or rebound, prevent it from radial displacement or twisting, thereby ensuring that the first elastic element can be stably compressed or reset in the axial direction when subjected to force, and improving the shock absorption performance.

[0013] In one optional embodiment, the wall of the housing located at the limiting sleeve has a protrusion forming a boss in the direction of extending into the limiting sleeve, the boss being spaced apart from and opposite to the end face of the wing plate; the two ends of the first elastic member abut against the wall surfaces opposite to the wing plate and the boss, respectively.

[0014] Beneficial effects: The boss extends from the shell wall into the limiting sleeve and is used to abut against the first elastic member; one end of the first elastic member abuts against the end face of the boss and the other end abuts against the end face of the wing plate. The boss provides abutment plane to prevent the first elastic member from being unstable due to the tilt of the inner wall of the shell. The boss provides a stable support position for the first elastic member. At the same time, the boss cooperates with the limiting sleeve to ensure the stability of the bottom end of the first elastic member, thereby ensuring that the elastic member can be stably compressed or rebounded along the axial direction when deformed, avoiding shaking or displacement due to unstable installation.

[0015] In one alternative embodiment, a gap is left between the limiting sleeve and the wing plate.

[0016] Beneficial effects: The end of the limiting sleeve that is away from the boss has a certain gap with the wing plate to prevent hard collision between the bracket wing plate and the limiting sleeve when the bracket vibrates due to motor vibration, thus preventing wear and reducing noise.

[0017] In one optional embodiment, a plurality of grooves or protrusions are formed on the inner wall of the mounting hole, and the second elastic member is provided with a plurality of protrusions or grooves at corresponding positions. The protrusions engage with the grooves to limit the connection between the second elastic member and the wing plate.

[0018] Beneficial effects: The protrusion and groove engage to effectively prevent the second elastic element from shifting or falling off during operation, ensuring that it can maintain a stable connection even under long-term vibration.

[0019] In one alternative embodiment, the fastener further includes a base connected to the fixing post, and the end plate is formed on the base.

[0020] In one optional embodiment, the first elastic element is a spring, and the wire diameter of the first elastic element is d, which satisfies 2mm≤d≤3mm.

[0021] Beneficial effects: The first elastic element can be a spring, and the value of the spring wire diameter d is in the range of 2mm≤d≤3mm. This setting ensures that the first elastic element has sufficient elasticity and strength to provide effective shock absorption and cushioning, while avoiding fatigue fracture of the first elastic element after long-term use due to excessively small wire diameter.

[0022] In one optional embodiment, the wing plate is provided with at least two pieces, and the at least two wing plates are respectively located on opposite sides of the motor; the first elastic member is provided with a plurality of pieces, and the plurality of first elastic members are respectively provided on opposite sides of the motor and respectively abut against the wing plate.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model according to the specific circumstances.

[0037] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0039] According to an embodiment of the present invention, a fascia gun is provided, comprising: a housing 1; a motor 2 disposed inside the housing 1; a support 3 having a support plate 31 and a wing plate 32 connected to the support plate 31; the support plate 31 is fixed to the motor 2, the wing plate 32 is spaced apart from and opposite to at least a portion of the housing 1, and a mounting hole 321 is provided through the wing plate 32; a fixing post 4, the first end of which is fixed to the inner wall of the housing 1, and the second end of which is movably disposed through the mounting hole 321; a first elastic member 5 disposed inside the housing 1, and both ends of which abut against the wing plate 32 and the opposite wall surface of the housing 1, respectively, the wing plate 32 being adapted to move along the axial direction of the fixing post 4 in the direction of compressing the first elastic member 5; and a second elastic member 6 sleeved on the fixing post 4 and sandwiched between the fixing post 4 and the inner wall of the mounting hole 321, the second elastic member 6 being limitedly connected to the wing plate 32.

[0040] It should be noted that the motor 2 inside the fascia gun in the relevant technology vibrates strongly, causing the housing 1 to vibrate significantly and generate a lot of noise, which affects the user experience and product performance. Furthermore, when the fascia gun is subjected to external impact or is accidentally dropped, the motor 2 is impacted, and the connection between the motor 2 and the housing 1 is prone to breakage, resulting in product damage and shortening the normal service life of the product.

[0041] Specifically, when the motor 2 is working, it will generate a large vibration. The first elastic element 5 is compressed and set between the bracket 3 and the inner wall of the housing 1. The vibration of the motor 2 causes the bracket 3 to vibrate. Since the two ends of the first elastic element 5 are respectively in contact with the bracket 3 and the inner wall of the housing 1, the first elastic element 5 will deform. The first elastic element 5 absorbs the vibration energy through its own elastic deformation, thereby reducing the transmission of vibration to the housing 1. When the fascia gun is hit by an external force or dropped, the motor 2 assembly is prone to displacement, which in turn causes the bracket 3 to move. Since the two ends of the first elastic element 5 are respectively in contact with the bracket 3 and the inner wall of the housing 1, the elastic element will deform, thereby absorbing the impact energy, thus effectively buffering the impact of external force on the motor 2 and the bracket 3, reducing the risk of bracket 3 breaking.

[0042] In this embodiment, a first elastic element 5 is provided inside the housing 1, with both ends abutting against the support 3 and the opposite wall surface of the housing 1. When the motor 2 vibrates or displaces, the vibration or displacement is transmitted to the first elastic element 5 through the support 3, causing the first elastic element 5 to undergo elastic deformation to absorb vibration energy and provide cushioning. Thus, when the motor 2 is working, the vibration transmitted to the housing 1 is effectively reduced through the shock absorption effect of the first elastic element 5, reducing product operating noise and improving user experience. At the same time, when the fascia gun is impacted or dropped by external force, the first elastic element 5 can provide cushioning to prevent the motor 2 assembly from directly bearing the impact, thereby effectively protecting the connection structure between the motor 2 and the housing 1, reducing the risk of damage, and extending the normal service life of the product.

[0043] In some embodiments, combined with Figure 8 As shown, the first elastic element 5 is arranged around the periphery of the fixed post 4.

[0044] In this embodiment, the fixing column 4 is used to connect the wing plate 32 and the housing 1. By circling the first elastic element 5 around its periphery, the first elastic element 5 is limited to prevent it from shifting or falling off when subjected to force, so that the first elastic element 5 is stably set at the motor 2. On the other hand, the end of the first elastic element 5 abuts against the wing plate 32. The circumferential arrangement increases the contact area between it and the bracket 3 and the housing 1, so that the first elastic element 5 is subjected to force evenly when subjected to vibration or impact, thereby improving the buffering effect.

[0045] Optionally, the elastic extension and contraction direction of the first elastic element 5 is consistent with the axial direction of the fixed column 4, so that the elastic element can deform along the axial direction of the fixed column 4 when subjected to force, ensuring that its compression and rebound process is stable and reliable.

[0046] In some embodiments, combined with Figure 6As shown, the fascia gun also includes a fastener 7, which is connected to the fixing post 4 and has an end plate 71 protruding radially along the fixing post 4. The end plate 71 abuts against the side of the elastic member opposite to the first elastic member 5.

[0047] It should be noted that the structural form of the wing plate 32 is not limited. In this embodiment, the wing plate 32 includes a base plate and a protrusion on the base plate. The mounting hole 321 is provided through the protrusion and the base plate. The protrusion can strengthen the structural strength of the wing plate 32. The second elastic member 6 is limited and connected to the wing plate 32. At the same time, the end plate 71 abuts against the side of the second elastic member 6 away from the first elastic member 5, so that the second elastic member 6 is limited and fixed in the mounting hole 321, thereby preventing it from displacing or falling off during operation.

[0048] Specifically, when the motor 2 is working, the second elastic element 6 is sandwiched between the fixed column 4 and the bracket 3. When the motor 2 vibrates and drives the bracket 3 to vibrate, the second elastic element 6 can effectively prevent hard collisions between the fixed column 4 and the bracket 3, thereby reducing noise. Furthermore, when the motor 2 vibrates and drives the bracket 3 to vibrate, the second elastic element 6 undergoes a certain elastic deformation, thereby playing a shock absorption and buffering effect and reducing the amount of vibration transmitted to the fixed column 4.

[0049] In this embodiment, by setting a second elastic element 6, it is clamped between the inner wall of the mounting hole 321 and the outer wall of the fixing column 4, and is limitedly connected with the wing plate 32 to prevent the motor 2 bracket 3 from directly contacting the fixing column 4. When the motor 2 is working, it prevents hard collisions between the fixing column 4 and the motor 2 bracket 3, reducing damage and noise. The fixing column 4 uses the cooperation of the second elastic element 6, the mounting hole 321 and the fastener 7 to achieve a flexible connection with the bracket 3, further improving the stability and shock absorption effect of the overall structure.

[0050] Optionally, the second elastic element 6 may be made of materials with elasticity and wear resistance, such as rubber or silicone.

[0051] In some embodiments, combined with Figure 4 and Figure 5 As shown, the fascia gun also includes a limiting sleeve 8, which is arranged around the periphery of the elastic member and fixed to the inner wall of the housing 1.

[0052] Specifically, the limiting sleeve 8 has a through hole and openings at both ends. One end of the limiting sleeve 8 is fixed to the inner wall of the housing 1. The first elastic member 5 extends into the limiting sleeve 8 and the end of the first elastic member 5 abuts against the inner wall of the housing 1 inside the limiting sleeve 8.

[0053] In this embodiment, the limiting sleeve 8 is fitted on the outer periphery of the first elastic member 5, which can effectively limit the deformation range of the first elastic member 5 during compression or rebound, prevent it from radially shifting or twisting, thereby ensuring that the first elastic member 5 can be stably compressed or reset in the axial direction when subjected to force, and improve the shock absorption performance.

[0054] In some embodiments, combined with Figure 4 As shown, the wall of the housing 1 located at the limiting sleeve 8 has a protrusion 11 protruding in the direction of extending into the limiting sleeve 8. The protrusion 11 is spaced apart from and opposite to the end face of the wing plate 32. The two ends of the first elastic member 5 abut against the opposite wall surfaces of the wing plate 32 and the protrusion 11, respectively.

[0055] In this embodiment, the boss 11 extends from the wall of the housing 1 into the limiting sleeve 8 and is used to abut against the first elastic member 5. One end of the first elastic member 5 abuts against the end face of the boss 11 and the other end abuts against the end face of the wing plate 32. The boss 11 provides an abutment plane to prevent the first elastic member 5 from being unstable due to the tilt of the inner wall of the housing 1. The boss 11 provides a stable support position for the first elastic member 5. At the same time, the boss 11 cooperates with the limiting sleeve 8 to ensure the stability of the bottom end of the first elastic member 5, thereby ensuring that when the elastic member is deformed, it can be stably compressed or rebounded along the axial direction, avoiding shaking or displacement due to unstable installation.

[0056] In some embodiments, combined with Figure 7 As shown, there is a gap between the limiting sleeve 8 and the wing plate 32.

[0057] In this embodiment, a certain gap is left between the end of the limiting sleeve 8 away from the boss 11 and the wing plate 32 to prevent hard collision between the wing plate 32 of the bracket 3 and the limiting sleeve 8 when the bracket 3 vibrates due to the vibration of the motor 2, thereby preventing wear and reducing noise.

[0058] In some embodiments, combined with Figure 5 As shown, a plurality of grooves 91 or protrusions 92 are formed on the inner wall of the mounting hole 321. The second elastic member 6 is provided with a plurality of protrusions 92 or grooves 91 at the corresponding positions. The protrusions 92 and the grooves 91 engage with each other, so that the second elastic member 6 is limited and connected to the wing plate 32.

[0059] In this embodiment, the second elastic member 6 and the mounting hole 321 are connected by a snap-fit ​​engagement of the groove 91 or the protrusion 92. The inner wall of the mounting hole 321 is recessed at the end opposite to the first elastic member 5 to form a groove 91. The second elastic member 6 protrudes at the corresponding position to form a protrusion 92. The protrusion 92 engages with the groove 91 to effectively prevent the second elastic member 6 from shifting or falling off during operation, ensuring that it can maintain a stable connection even under long-term vibration.

[0060] In some embodiments, combined with Figure 5 As shown, the fastener 7 also includes a base 72, which is connected to the fixing post 4, and the end plate 71 is formed at the base 72.

[0061] Specifically, the base 72 can be a stud, and a threaded hole is provided through the fixing post 4. The stud and the threaded hole are connected by a threaded engagement to achieve a stable connection between the base 72 and the fixing post 4. At the same time, the end plate 71 is connected to the end of the base 72 and is used to abut against the second elastic member 6.

[0062] In some embodiments, combined with Figure 4 As shown, the first elastic element 5 is a spring, and the wire diameter of the first elastic element 5 is d, which satisfies 2mm≤d≤3mm.

[0063] Specifically, the spring wire diameter refers to the diameter of the metal wire that makes up the spring. In this embodiment, the first elastic element 5 can be a spring, and the value of the spring wire diameter d is in the range of 2mm≤d≤3mm, specifically 2.5mm. This setting ensures that the first elastic element 5 has sufficient elasticity and strength to provide effective shock absorption and buffering, while avoiding fatigue fracture of the first elastic element 5 after long-term use due to the wire diameter being too small.

[0064] Optionally, the material of the spring can be, but is not limited to, piano wire. Piano wire is a type of fatigue-resistant carbon steel wire used in mechanical springs, which is cold-drawn after being quenched in a lead bath to produce a high-strength carbon steel spring material.

[0065] In some embodiments, combined with Figure 6 As shown, the wing plate 32 is provided with at least two pieces, and the at least two wing plates 32 are respectively located on opposite sides of the motor 2; the first elastic member 5 is provided with a plurality of pieces, and the plurality of first elastic members 5 are respectively provided on opposite sides of the motor 2 and respectively abut against the wing plate 32.

[0066] In this embodiment, there are two wing plates 32, which are arranged on opposite sides of the motor 2. At the same time, there are four first elastic elements 5, which are arranged in pairs on opposite sides of the motor 2 and cooperate with the wing plates 32 respectively. The two first elastic elements 5 located on the same side of the motor 2 are connected at intervals to the same wing plate 32 to achieve balanced support and shock absorption for the motor 2 as a whole.

[0067] The specific assembly process of the fascia gun is as follows: the housing 1 includes an interlocking upper cover 13 and a lower cover 14, and the fixing post 4 and the limiting sleeve 8 are connected to the lower cover 14, as shown below. Figure 8As shown, the number of limiting sleeves 8 and fixing posts 4 corresponds to the number of first elastic elements 5. First, the first elastic elements 5 are fitted one by one around the fixing posts 4, while the first elastic elements 5 extend into the limiting sleeves 8, and the ends of the first elastic elements 5 contact the bosses 11. Then, the motor 2, the bracket 3, and the transmission assembly 10 are connected together to form a motor assembly. The transmission assembly 10 refers to the structure connecting the motor 2 and the massage head. The transmission assembly 10 is an existing component, consisting of multiple transmission arms connected by transmission. Then, the mounting holes 321 of the motor assembly are aligned and inserted into the fixing posts 4. The second elastic elements 6 and fasteners 7 are assembled into the mounting holes 321 and the ends of the fixing posts 4, and the fasteners 7 are locked, so that the bracket 3 is connected to the fixing posts 4. At the same time, the first elastic elements 5 are compressed between the limiting sleeves 8 and the bracket 3. After that, the upper cover 13 and the lower cover 14 are fastened together to complete the assembly.

[0068] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
