Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a massage device and its vibration damping device. Background Technology

[0002] In related technologies, massage guns typically use a motor inside the housing to drive an eccentric wheel to rotate, which in turn drives a connecting rod to swing back and forth. This, in turn, causes the massage head connected to the connecting rod to extend and retract. The massage head then contacts the muscles to perform the massage operation. During the massage, the reaction force received by the massage head is also transmitted back to the motor through the connecting rod and the eccentric wheel, which can easily cause the housing to vibrate and generate significant noise, and also reduces the grip feel. Utility Model Content

[0003] In view of the above-mentioned technical problems, the present invention provides a massage device and a vibration reduction device thereon to reduce the vibration caused by the reaction force on the motor output shaft, so as to at least partially solve the above-mentioned technical problems.

[0009] Optionally, the damping plate includes a frame and a damping layer integrally formed outside the frame.

[0010] Optionally, the first mounting hole and the second mounting hole are provided in the vibration damping layer, and the frame is provided with a third mounting hole coaxial with the first mounting hole and a fourth mounting hole coaxial with the second mounting hole.

[0011] Optionally, the edges of the skeleton are provided with flanges, and / or the surface of the skeleton is provided with adhesive holes.

[0013] A second aspect of this utility model provides a massage device, including a body, a motor, an eccentric wheel assembly, a connecting rod assembly, a massage head, and a vibration damping device as described in any of the above optional solutions.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In related technologies, massage guns typically use a motor inside the housing to drive an eccentric wheel to rotate, which in turn drives a connecting rod to swing back and forth. This, in turn, causes the massage head connected to the connecting rod to extend and retract. The massage head then contacts the muscles to perform the massage operation. During the massage, the reaction force received by the massage head is also transmitted back to the motor through the connecting rod and the eccentric wheel, which can easily cause the housing to vibrate and generate significant noise, and also reduces the grip feel.

[0028] In view of the above-mentioned technical problems, the first aspect of this utility model provides a vibration damping device that can be used in massage equipment. (See reference...) Figures 1 to 7 As shown, the vibration damping device includes a vibration damping plate 1, wherein the vibration damping plate 1 is provided with a first mounting hole 110 and a second mounting hole 120, the motor output shaft of the massage device can pass through the first mounting hole 110, and the second mounting hole 120 is used to connect to the motor through a fastener; the vibration damping plate 1 can at least partially absorb the force on the first mounting hole 110 when the output shaft rotates.

[0029] Through the above technical solution, namely the vibration damping device provided by this utility model, when the massage device is used for massage operation, the output shaft of the massage device motor can be inserted into the first mounting hole 110 of the vibration damping plate 1, and a fastener (such as a screw, bolt, or positioning pin) can be inserted into the second mounting hole 120 to fix the vibration damping plate 1 to the motor. When the motor of the massage device is running, the rotation of the motor output shaft will drive the eccentric wheel and connecting rod to move, and finally drive the massage head to extend and retract. The reaction force of the massage head contacting the muscle will also be transmitted back to the output shaft of the motor through the connecting rod and eccentric wheel, causing the output shaft of the motor to shake. When the output shaft of the motor shakes, the side wall of the motor output shaft will make high-frequency contact with the inner wall of the first mounting hole 110. The shaking generated by the output shaft of the motor can be absorbed by the vibration damping plate 1 at this time. With the elastic buffering effect of the vibration damping plate 1 itself, the shaking generated by the output shaft of the motor can be reduced or even prevented from continuing to be transmitted to the outside, thereby reducing the vibration of the massage device housing, so as to reduce the noise and reduced grip feel caused by vibration.

[0030] It should be noted that the purpose of the fastener mentioned in the above specific embodiment is to connect with the main body of the motor to fix the relative position of the vibration damping device and the motor, thereby reducing or avoiding the occurrence of the vibration damping device swaying due to the rotation of the motor's output shaft, and improving the vibration damping effect of the vibration damping device.

[0031] Furthermore, in the above embodiments, in order to improve the vibration damping effect of the vibration damping device, the material used for the vibration damping plate 1 can also be any material with good vibration damping capacity, such as the reference material. Figures 1 to 3As shown, the damping plate 1 can be made of a composite material of nylon and glass fiber. The nylon can be nylon 66, which is a material formed by the condensation of adipic acid and hexamethylenediamine, and 20% to 30% glass fiber can be added to increase the structural strength and damping performance.

[0032] In some implementations, to improve the stability of the connection between the damping plate 1 and the motor, it can be combined with... Figure 1 , Figure 6 and Figure 7 As shown, there can be multiple second mounting holes 120, and multiple second mounting holes 120 are arranged at intervals along the circumference of the first mounting hole 110 on the vibration damping plate 1.

[0033] With the above solution, when the damping plate 1 is connected to the motor, due to the presence of multiple second mounting holes 120, the damping plate 1 can be connected to the motor through multiple fasteners passing through the second mounting holes 120. This multiple fasteners improve the stability of the connection between the damping plate 1 and the motor. Figure 1 In this arrangement, the number of second mounting holes 120 can be three, and any two of the three second mounting holes 120 are spaced 120° apart along the circumference of the first mounting hole 110. In this arrangement, the three second mounting holes 120 are arranged in a triangular manner along the first mounting hole 110, which can achieve the limiting and fixing of the damping plate 1 by fasteners at multiple points to improve the fixing stability.

[0034] It should be noted that the second mounting hole 120 can be a through hole or a threaded hole, and the motor surface can also be provided with threaded holes corresponding to the position of the second mounting hole 120. In this embodiment, when the second mounting hole 120 is a threaded hole, the fastener can be as follows: Figure 6 and Figure 7 The screw shown can be threaded onto the threaded hole on the motor surface after passing through the second mounting hole 120 which is configured as a threaded hole, so as to achieve fixation.

[0035] Alternatively, when the second mounting hole 120 is a through hole, the motor surface can also be provided with a threaded hole corresponding to the position of the through hole, and the screw can also be threaded into the threaded hole on the motor surface after passing through the through hole, so as to fix the vibration damping plate 1 to the motor.

[0036] In some implementations, reference Figures 1 to 3 As shown, the damping plate 1 includes a first surface 101 and a second surface 102. A first mounting hole 110 and a second mounting hole 120 pass through the first surface 101 and the second surface 102. The second surface 102 cooperates with the motor and is provided with a reinforcing structure 130.

[0037] With the above scheme, the first mounting hole 110 and the second mounting hole 120 pass through the first surface 101 and the second surface 102, which facilitates the installation of the motor output shaft and the installation and fixing of the fasteners. The reinforcing structure 130 can further improve the structural strength of the damping plate 1 itself, so as to have better impact resistance and shock absorption capabilities.

[0038] Further, refer to Figures 1 to 3 As shown, the second surface 102 is provided with a recess 103, and a reinforcing structure 130 is disposed in the recess 103. The reinforcing structure 130 includes a first reinforcing part 131 and a second reinforcing part 132. The first reinforcing part 131 is annular, and a first mounting hole 110 and a second mounting hole 120 are located in the first reinforcing part 131. One end of the second reinforcing part 132 is connected to the first reinforcing part 131, and the other end is connected to the inner wall of the recess 103.

[0039] The above solution allows for a lightweight design of the vibration damping device by setting the recessed portion 103. The first mounting hole 110 and the second mounting hole 120 are both located inside the first reinforcing portion 131, which can further improve the structural strength around the first mounting hole 110 and the second mounting hole 120, thereby indirectly improving the vibration damping effect on the motor output shaft and improving the stability of the connection between the fastener passing through the second mounting hole 120 and the motor, thus improving the stability of the fixed connection between the vibration damping plate 1 and the motor.

[0040] The second reinforcing part 132 can serve as an additional reinforcing rib to further enhance the reinforcing effect of the first reinforcing part 131, as can be seen from [reference needed]. Figure 2 As shown, multiple second reinforcing parts 132 can be spaced out in the outer circumference of the first reinforcing part 131, and one end of each of the multiple second reinforcing parts 132 extends away from the first reinforcing part 131 to improve the overall structure of the reinforcing damping plate 1.

[0041] To further improve the structural strength or stiffness of damping plate 1, you can refer to... Figures 1 to 4 As shown, the damping plate 1 may include a frame 140 and a damping layer 150 integrally formed outside the frame 140.

[0042] In this way, the frame 140 can further improve the structural strength or stiffness of the damping plate 1. The frame 140 can be made of aluminum alloy plate by stamping, while the damping layer 150 on the outside of the frame 140 can be integrally manufactured by injection molding. As can be seen from the above specific embodiments, when the damping layer 150 is made of a composite material of nylon and glass, the stamped frame 140 can be placed into the injection mold, and the composite material can be injected into the mold to fuse the frame 140 and the damping layer 150, so as to finally integrally form the damping plate 1. In this way, the structural strength of the damping plate 1 can be improved, and the damping plate 1 can also ensure that the damping plate 1 has a good damping effect on the output shaft of the motor.

[0043] In some implementations, reference Figures 1 to 4 As shown, the first mounting hole 110 and the second mounting hole 120 are provided on the vibration damping layer 150, and the frame 140 is provided with a third mounting hole 141 coaxial with the first mounting hole 110 and a fourth mounting hole 142 coaxial with the second mounting hole 120.

[0044] In the process of manufacturing the damping plate 1 as a whole, the frame 140 can be stamped first, and holes can be drilled at the positions of the third mounting hole 141 and the fourth mounting hole 142 on the frame 140. Then, the drilled frame 140 can be put into the mold for injection molding. After the damping layer 150 is injection molded and cooled, holes can be drilled at the positions of the third mounting hole 141 and the fourth mounting hole 142 to create the first mounting hole 110 and the second mounting hole 120. The coaxiality of the first mounting hole 110 and the third mounting hole 141 can not only ensure the structural fixation of the damping plate 1, but also improve the damping effect. The coaxiality of the second mounting hole 120 and the fourth mounting hole 142 can improve the coaxiality of the fixing parts installation and positioning, thereby improving the stability of the connection between the damping plate 1 and the motor.

[0045] To further improve the stability of the connection between the frame 140 and the damping layer 150 and / or the convenience of the overall processing of the damping plate 1, reference can be made to... Figure 4 As shown, the edge of the skeleton 140 may be provided with a flange 143, and / or the surface of the skeleton 140 is provided with a glue-pulling hole 144.

[0046] Through the above scheme, the flange 143 can increase the contact area with the frame 140 after the damping layer 150 of the damping plate 1 is injection molded, and can play a certain positioning role, thereby making the connection between the frame 140 and the damping layer 150 more stable. In addition, the flange 143 can also improve the structural strength of the frame 140 and make the frame 140 have stronger bending resistance. The glue-pulling hole 144 can facilitate the injection molding of glue to manufacture the damping layer 150 after the frame 140 is manufactured and placed into the mold.

[0047] In some implementations, reference Figures 1 to 3 ,as well as Figure 6 As shown, the damping plate 1 also includes a cable management groove 160.

[0048] By setting up the cable management groove 160, the motor's lead wires can be constrained within the cable management groove 160, thereby reducing or preventing scratches from moving components of the massage device, such as connecting rods, eccentric wheels, or the motor housing.

[0049] A second aspect of this utility model provides a massage device, as shown in the reference. Figures 1 to 7 As shown, the massage device includes a body 2, a motor 3, an eccentric wheel assembly 4, a connecting rod assembly 5, a massage head 6, and a vibration damping device mentioned in the above specific embodiments, and the vibration damping device has all the beneficial effects of the above specific embodiments.

[0050] The motor 3, eccentric wheel assembly 4 and connecting rod assembly 5 are all located inside the body 2. The output shaft of the motor 3 is connected to the eccentric wheel assembly 4 and passes through the first mounting hole 110 of the vibration damping device. The eccentric wheel assembly 4 is connected to the connecting rod assembly 5, and the connecting rod assembly 5 is connected to the massage head 6.

[0051] In this connection method, when the massage device is performing a massage operation, the motor 3 inside the body 2 starts. The output shaft of the motor 3 passes through the first mounting hole 110 and is connected to the eccentric wheel assembly 4, driving the eccentric wheel assembly 4 to rotate. The rotation of the eccentric wheel assembly 4 can drive the connecting rod assembly 5 to reciprocate and extend, thereby driving the massage head 6 to extend and retract to achieve the massage effect. When the massage head 6 contacts the muscle, the reaction force received by the massage head 6 will also be transmitted back. The reaction force is transmitted back to the output shaft of the motor 3 through the connecting rod assembly 5 and the eccentric wheel assembly 4 in sequence, which can easily cause the output shaft of the motor 3 to vibrate significantly. However, since the output shaft of the motor 3 passes through the first mounting hole 110 of the vibration damping device, the vibration damping plate 1 can absorb this vibration, thereby allowing the output shaft of the motor 3 to remain as stable as possible without generating too much vibration, thus improving the grip feel of the massage device.

[0052] 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 such modifications and variations all fall within the scope of protection claimed in this application.
