Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment technology, and in particular to a fascia gun. Background Technology
[0002] With the rapid development of the fitness and rehabilitation field, fascia guns are widely used due to their efficient muscle relaxation and sports injury relief functions. To improve efficiency, dual-head fascia gun designs have gradually emerged in the market. However, existing dual-head fascia guns have significant structural design flaws: First, the redundant layout of the dual power modules and transmission mechanism leads to a surge in the number of parts, resulting in complex assembly processes, high production costs, and accumulated tolerances between components affecting overall stability. Second, uneven load distribution during asynchronous dual-head operation can easily cause stress concentration in the shell, which can lead to deformation of the internal support or misalignment of the motor shaft after long-term use, resulting in abnormal vibration and noise, seriously affecting user experience and product reliability. Third, the multi-point plug-in connection structure used to accommodate dual-head swinging lacks mechanical optimization, making it prone to breakage or loosening at connection points during accidental drops or external impacts, posing a safety hazard.

[0032] This utility model proposes a fascia gun.
[0033] Please see Figures 1 to 5 In one embodiment of this utility model, the fascia gun 100 includes a housing assembly 1, a mechanism assembly 2, and a massage head (not shown). The housing assembly 1 includes a housing body 11 and a mounting base 12. The housing body 11 has an internal receiving cavity 11a and a mounting opening 11b communicating with the receiving cavity 11a on its side surface. The integrally formed mounting base 12 covers the housing body 11 and is located at the mounting opening 11b. The mounting base 12 has two spaced mounting holes 12a communicating with the mounting opening 11b. The mechanism assembly 2 includes... The device includes two pistons 21, two connecting rod assemblies 22, and at least one drive motor 23. The two pistons 21 are respectively disposed in two mounting holes 12a of the mounting base 12 and are movably disposed along the axial direction of the holes. The drive motor 23 is disposed in the receiving cavity 11a. The two pistons 21 are connected to the drive motor 23 through the two connecting rod assemblies 22. The drive motor 23 can drive the pistons 21 to perform high-frequency reciprocating motion within the mounting holes 12a. A massage head is detachably provided at the end of the piston 21 away from the connecting rod assembly 22 for massaging human tissue.
[0034] For the two connecting rod assemblies 22, two drive motors 23 can be installed inside the housing body 11, with each drive motor 23 connected to one connecting rod assembly 22. Alternatively, a dual-axis drive motor 23 can be installed inside the housing body 11, with two output shafts 231 simultaneously connected to both connecting rod assemblies 22 to achieve drive. The number of drive motors 23 is not specifically limited. The connecting rod assembly 22 may include a connecting rod and bearings installed at both ends of the connecting rod, and can be rotatably connected by eccentric wheels on the output shaft of the drive motor 23 and on the piston 21. Of course, the connecting rod assembly 22 may also adopt other connection methods to achieve high-frequency reciprocating motion of the piston 21 within the mounting hole 12a, which is also not specifically limited here.
[0035] As can be seen from the above, the integrated mounting base 12 reduces the number of structural parts in the double-headed fascia gun 100, simplifies the structure, streamlines the installation process, and improves production efficiency. Furthermore, the integrated mounting base 12 has higher structural strength, making it less likely for the joints of the parts to break or loosen when subjected to impact, thus improving product quality.
[0036] In one embodiment, the housing assembly 1 further includes a connector 13 disposed between the housing body 11 and the mounting base 12. The connector 13 is provided with two first through holes 13a. The two ends of each first through hole 13a are respectively connected to the mounting port 11b and a mounting hole 12a. The first through hole 13a is used for the connecting rod assembly 22 to pass through.
[0037] like Figure 2 As shown, in one embodiment of this utility model, the outer shell assembly 1 further includes a connector 13. Specifically, the connector 13 is disposed between the shell body 11 and the mounting base 12. Two first through holes 13a are provided on the connector 13 corresponding to the two mounting holes 12a of the mounting base 12. One end of each first through hole 13a communicates with the mounting opening 11b of the shell body 11, and the other end communicates with the mounting hole 12a of the mounting base 12. Figure 7 It is known that the piston 21 is located within the mounting hole 12a, and the connecting rod assembly 22 passes through the first through hole 13a and is connected to the piston 21 and the drive motor 23 respectively. In this design, the first through hole 13a of the connector 13 provides sufficient space for the connecting rod assembly 22 to move. The connector 13 is also an integrally formed structure. The connector 13 and the mounting base 12 together provide support, which can improve the working stability of the two massage heads and the overall structural strength of the fascia gun 100. Of course, in some other embodiments of this utility model, the mounting base 12 and the connector 13 can be set as an integral structure to further improve product quality.
[0038] In one embodiment, the housing assembly 1 further includes a sleeve assembly 15. Each mounting hole 12a on the mounting base 12 is provided with a sleeve assembly 15 for limiting. The inner wall of the mounting hole 12a is provided with a step portion 121 that abuts against the sleeve assembly 15 for limiting. The side of the connector 13 away from the housing body 11 is provided with a protrusion 131, which abuts against the side of the sleeve assembly 15 away from the step portion 121.
[0039] like Figures 2 to 4 As shown, in one embodiment of this utility model, the outer shell assembly 1 further includes a sleeve assembly 15. Specifically, the two mounting holes 12a of the mounting base 12 are respectively provided with sleeve assemblies 15, and the piston 21 is movably installed in the sleeve assembly 15. (Referring to the reference...) Figure 7In order to limit the sleeve assembly 15, two stepped portions 121 are formed on the inner wall of the mounting hole 12a. The end of the sleeve assembly 15 away from the connector 13 extends into the mounting hole 12a and abuts against one of the stepped portions 121. The end of the sleeve assembly 15 near the connector abuts against the other stepped portion 121. The connector 13 is provided with an annular protrusion 131 on the side near the mounting base 12 and circumferentially located in the first through hole 13a. The protrusion 131 abuts against the side of the sleeve assembly 15 away from the stepped portion 121 to limit the sleeve assembly 15 on the mounting base 12.
[0040] As can be seen from the above, by using the connector 13 to confine the two sleeve assemblies 15 within the mounting base 12, the installation steps are simpler and easier to assemble to improve production efficiency. Furthermore, by using the one-piece molded connector 13 and mounting base 12 to fasten together, the stability of the piston 21 and the sleeve assembly 15 is better, which can reduce structural deformation caused by external forces.
[0041] In one embodiment, the connector 13 is provided with a plurality of first threaded holes 13b at a position away from the first through hole 13a, and the mounting base 12 is provided with a plurality of first mating holes 12b corresponding to the first threaded holes 13b. The connector 13 is connected to the mounting base 12 by screws passing through the first mating holes 12b and the first threaded holes 13b in sequence.
[0042] like Figure 3 As shown, in one embodiment of this utility model, the connector 13 has a plurality of first threaded holes 13b located between two through holes, and the mounting base 12 has a plurality of first mating holes 12b located between two mounting holes 12a. The first threaded holes 13b and the first mating holes 12b are arranged in a one-to-one correspondence. By passing a screw through the first mating hole 12b and screwing it into the first threaded hole 13b, the connector 13 can be connected to the mounting base 12. During assembly, the sleeve assembly 15 can be inserted into the mounting hole 12a first, and then the screws can be used to connect it to confine the sleeve assembly 15 within the mounting hole 12a.
[0043] Using screws for fastening facilitates disassembly and maintenance, and reduces manufacturing costs. In some other embodiments of this utility model, the connector 13 and the mounting base 12 can also be connected by means of slot pin, strong adhesive bonding, hot melt welding, snap-fit connection, etc. The specific connection method can be selected according to the material and structure of the connector 13 and the mounting base 12. The material of the connector 13 and the mounting base 12 can be plastic or metal, and no specific limitation is made here.
[0044] In one embodiment, the housing assembly 1 further includes a decorative member 14 disposed between the connector 13 and the mounting base 12. The decorative member 14 has a second through hole 14a corresponding to the protrusion 131, and a through hole corresponding to the first mating hole 12b. The screw passes through the first mating hole 12b, the second through hole 14a, and the first threaded hole 13b in sequence.
[0045] Furthermore, such as Figure 2 and Figure 3 As shown, in order to improve the aesthetics of the fascia gun 100, in one embodiment of the present invention, the outer shell assembly 1 further includes a decorative member 14. Specifically, the decorative member 14 is disposed between the connector 13 and the mounting base 12. The decorative member 14 is provided with two second through holes 14a corresponding to the two protrusions 131 of the connector 13. The decorative member 14 is sleeved on the two protrusions 131 of the connector 13 through the second through holes 14a. The decorative member 14 is also provided with through holes that match the first threaded hole 13b and the first mating hole 12b for screw insertion.
[0046] In one embodiment, a drive motor 23 is provided inside the housing body 11, and a motor bracket 24 is provided on both sides of the drive motor 23 inside the housing body 11. The drive motor 23 has two output shafts 231, each of which extends into a motor bracket 24 and is driven connected to the end of a connecting rod assembly 22 away from the piston 21.
[0047] like Figure 2 , Figure 5 and Figure 7 As shown, in one embodiment of this utility model, a drive motor 23 with dual output shafts 231 is provided inside the shell body 11. Specifically, the drive motor 23 is located inside the shell body 11 and in the receiving cavity 11a near the mounting port 11b. The shell body 11 is cylindrical and a motor bracket 24 is provided on both sides of the drive motor 23 in the receiving cavity 11a. The motor bracket 24 is a hollow structure and has an opening on the side wall facing the mounting port 11b. The two output shafts 231 of the drive motor 23 extend into the two motor brackets 24 respectively and are provided with eccentric wheels. The end of the connecting rod assembly 22 away from the piston 21 passes through the mounting port 11b into the interior of the motor bracket 24 and connects with the eccentric wheel.
[0048] Understandably, setting up a dual-axis single motor can save internal space in the housing body 11, which is beneficial for controlling the overall size and manufacturing cost of the fascia gun 100. Setting up motor brackets 24 on both sides of the drive motor 23 can improve the installation stability of the drive motor 23 and reduce vibration and noise.
[0049] In one embodiment, the motor bracket 24 is provided with a plurality of second threaded holes 24a, and the connector 13 is provided with a plurality of second mating holes 13c corresponding to each second threaded hole 24a of the motor bracket 24. The connector 13 is connected to the motor bracket 24 by screws passing through the second mating holes 13c, the mounting port 11b and the second threaded holes 24a in sequence.
[0050] like Figures 3 to 5 As shown, in one embodiment of this utility model, the motor bracket 24 is provided with a plurality of second threaded holes 24a on the side facing the mounting port 11b, and the connector 13 is provided with a plurality of second mating holes 13c through the protrusion 131. When the connector 13 is attached to the mounting port 11b of the shell body 11, the plurality of second threaded holes 24a and the plurality of second mating holes 13c are provided one-to-one. By using screws to pass through the second mating holes 13c and the mounting port 11b in sequence and screwing them into the second threaded holes 24a, the motor bracket 24 and the connector 13 can be connected and the shell body 11 can be clamped. Combined with the connection of the connector 13 to the mounting base 12 by screws as described above, the assembly tightness between the parts can be further improved, thereby improving the structural strength.
[0051] During installation, first, the drive motor 23 and motor bracket 24 are inserted into the receiving cavity 11a of the housing body 11 and aligned with the mounting port 11b. Then, the connecting rod assembly 22 with piston 21 is connected to the drive motor 23. Next, the piston 21 and connecting rod are passed through the first through hole 13a of the connector 13, and the connector 13 is connected to the motor bracket 24 with screws. Then, the decorative piece 14 is fitted onto the protrusion 131 of the connector 13. Next, the sleeve assembly 15 is inserted into the mounting hole 12a of the mounting base 12. Finally, the mounting base 12 is connected to the connector 13 with screws to clamp the decorative piece 14. The above is a general installation process for the components of the fascia gun 100 proposed in this utility model. It can be seen that the various components of the fascia gun 100 are tightly connected, and the connection points are not prone to breakage or loosening in the event of an accidental drop or impact, thus avoiding safety hazards during use.
[0052] In one embodiment, the motor bracket 24 is provided with a plurality of third threaded holes 24b, and the housing body 11 is provided with a plurality of third mating holes 11c corresponding to the plurality of third threaded holes 24b. The housing body 11 is fitted with screws through the third mating holes 11c and the third threaded holes 24b in sequence to limit the motor bracket 24 to be installed in the receiving cavity 11a.
[0053] like Figure 4 and Figure 5As shown, in one embodiment of this utility model, the motor bracket 24 is provided with a plurality of third threaded holes 24b on the side facing the mounting port 11b, and the outer wall of the housing body 11 is provided with a plurality of third mating holes 11c corresponding to the third threaded holes 24b. Before the drive motor 23 and the motor bracket 24 are installed in the housing body 11 and before the connector 13 is installed, screws can be screwed into the third threaded holes 24b through the third mating holes 11c to fix the two motor brackets 24 in the receiving cavity 11a. It can be understood that the connector 13, the mounting base 12, and the drive motor 23 are fixed to the housing body 11 only through the motor bracket 24, reducing the connection structure to make assembly simpler and more convenient, and improving the production efficiency of the product.
[0054] In one embodiment, a plurality of third threaded holes 24b are arranged around the projection of the mounting hole 12a at the mounting opening 11b, and a plurality of protrusions 111 are provided along the outer side wall of the motor bracket 24 at the edge of the mounting opening 11b, and at least a portion of the third mating holes 11c are provided on the protrusions 111.
[0055] like Figure 5 As shown, in one embodiment of this utility model, in order to prevent the third threaded hole 24b from interfering with the connecting rod assembly 22, a plurality of third threaded holes 24b are arranged around the projection of the mounting hole 12a at the mounting opening 11b. A plurality of protrusions 111 extend from the edge of the mounting opening 11b toward the middle position of the mounting opening 11b. The plurality of protrusions 111 extend along the outer side wall of the motor bracket 24 and the third mating hole 11c is opened on the protrusions 111, so that the motor bracket 24 can be fixed in the housing body 11 by screws.
[0056] It should be noted that the protrusion 111 is to cooperate with the third threaded hole 24b on the motor bracket 24. Its position and number are not specifically limited and can be set according to actual needs. In some other embodiments of this utility model, when the third threaded hole 24b of the motor bracket 24 surrounds the mounting opening 11b, the edge of the mounting opening 11b does not need to be provided with the protrusion 111.
[0057] In one embodiment, the third mating hole 11c is provided on the side of the connector 13 away from the mounting base 12, and the connector 13 is provided with a relief groove 13d at the position corresponding to the third mating hole 11c, so as to avoid the screws of the connecting shell body 11 and the motor bracket 24.
[0058] like Figure 4As shown, in one embodiment of this utility model, the third mating hole 11c is aligned with the side wall of the connector 13 away from the mounting base 12. In order to improve the aesthetics of the fascia gun 100, the connector 13 is recessed on the side wall facing the shell body 11 with a relief groove 13d. The relief groove 13d is used to avoid the screws connecting the shell body 11 and the motor bracket 24, so that the connector 13 can fit tightly against the outer side wall of the shell body 11 and hide the screws inside the connector 13, making the appearance of the fascia gun 100 more simple and design-oriented.
[0059] Of course, in some other embodiments of this utility model, considering the convenience of installation, the installation steps are set to first connect the mounting base 12 and the connector 13, and then install the connector 13 and the mounting base 12 assembly onto the shell body 11. At this time, the second mating hole 13c on the connector 13 can be set on the outside to facilitate the connection between the connector 13 and the motor bracket 24. Other structures can be adjusted accordingly, and no specific limitations are made here.
[0060] In addition, please refer to Figure 7 The fascia gun 100 also includes a battery assembly 3 disposed in the housing body 11 and a control board assembly 4 electrically connected to the battery assembly 3. The control board assembly 4 is used to control the operation of the drive motor 23, and its structure will not be described in detail.
[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope 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 patent protection scope of the present utility model.
