[0035] like Figure 1-Figure 3 As shown, the utility model provides an embodiment of a telescopic swing transmission mechanism.

[0036] The telescopic swing transmission mechanism includes a fixed frame 2 and a bracket 1 with one end movably connected to the fixed frame 2, and a driving component 4 that enables the other end of the bracket 1 to telescope and swing. The driving component 4 includes a motor 41 and a swing wheel 43 connected to a motor shaft (not shown in the drawings) and capable of sliding along the motor shaft. The swing wheel 43 is provided with a swing shaft 44 that drives one end of the bracket 1 to swing. A toggle member 42 is provided between the swing wheel 44 and the motor 41. When the toggle member 42 cooperates with the rotating swing wheel 43, the swing wheel 43 can be extended and retracted along the axial direction of the motor shaft.

[0037] Specifically, the swing shaft 44 is not in the same straight line as the motor shaft, and an angle a is formed between the swing shaft 44 and the motor shaft, and the driving component 4 causes the bracket 1, which is fixed at one end, to swing at the other end. The angle a formed between the swing shaft 43 and the motor shaft is an acute angle. The driving component 4 includes a motor 41 and a swing wheel 43 connected to the motor shaft 41, a toggle member 42 is provided between the swing wheel 43 and the motor 41, the motor 41 is fixed to the base 40 through a motor base 47, the toggle member 42 is fixed to the base 40, and an elastic fixing component 7 is provided between the swing wheel 43 and the motor shaft, which moves along the axial direction of the motor shaft.

[0038] During operation, the swing wheel 43 rotates under the drive of the motor 41. Due to the bevel fit between the swing wheel 43 and the moving member 42, the swing wheel 43 rotates and the toggle member 42 causes the swing wheel 43 to move away from the motor along the motor shaft, that is, to telescopically move along the motor shaft. When the swing wheel 43 rotates, the swing shaft 44 on the swing wheel 43 drives one end of the bracket 1 to move. The elastic fixing component includes a fixing pin 71 fixed to the motor shaft and a spring 72 sleeved on the fixing pin 71 to move the swing wheel 43 toward the motor. The toggle member 42 includes a body 420 and a toggle portion 421 provided on the mating surface between the body 420 and the swing wheel to enable the swing wheel 43 to telescopically move along the motor shaft. The toggle portion 421 includes a protrusion 423 extending along the motor shaft.

[0039] In order to reduce resistance and noise, the side of the protrusion 423 is set as an inclined surface 422, and the inclined surface 422 cooperates with the elastic fixing component 7 to realize the extension movement of the swing wheel 43. The protrusion 423 can be set as multiple as needed. In this case, a groove 424 is set between adjacent protrusions 423. Multiple protrusions 423 are evenly distributed in an annular shape on a circle with the motor shaft as the center. When the body 421 is set as a circle, the protrusions 423 are evenly distributed on the radial edge of the body 421. In this way, the toggle member 42 is set to cooperate with the swing wheel 43, which can not only realize the swing movement of the bracket 1, but also realize the smooth and continuous telescopic movement of the bracket 1, and can also amplify the output torque of the motor, thereby avoiding the increase of the load on the motor due to excessive resistance of the bracket during use, which affects the service life. The protrusion 423 and the groove 424 are connected by a smooth connection. For example, the protrusion 423 and the groove 424 are set as an annular wave structure, that is, the side of the protrusion 423 or the side wall of the groove 424 is set as an arc surface, which can realize continuous telescopic movement during the rotation of the swing wheel 43. The bottom of the bracket 1 is provided with a bearing (not shown in the figure) matched with the swing shaft 44, which can reduce the frame momentum of the swing shaft 44 and the bracket 1, prolong the service life, and reduce noise.

[0040] An elastic component 32 is provided between the bracket 1 and the fixing frame 2, which is partially retracted and stretched when the bracket 1 swings. The elastic component 32 is set as an annular structure, such as an annular silicone, or can be made of other materials to achieve partial retraction and stretching when the bracket swings. A fixing component 3 for fixing the elastic component 32 is provided between the bracket 1 and the fixing frame 2. The fixing component 3 includes a lower fixing sleeve 31 that is sleeved on the bracket 1 to fix the lower end of the elastic component 32 and an upper fixing sleeve 33 that directly or indirectly fixes the upper end of the elastic component 32 to the fixing seat 2. In order to improve the fixing effect, a fixing groove (not shown in the figure) is provided between the elastic component 32 and the bracket 1

[0041] When in use, the motor 41 drives the swing wheel 43 to rotate synchronously, and the swing shaft 44, which is not coaxial with the swing wheel 43, rotates with the swing wheel 43, which is coaxial with the motor shaft, as the shaft, driving one end of the bracket 1 to rotate, while the other end is connected to the fixing seat 2 by the elastic component 32 and does not rotate, so as to realize the swinging motion of one end of the bracket 1. At the same time, the rotating swing wheel 43 cooperates with the protrusion 423 and the groove 424 on the stationary toggle part 421, and the swing wheel 43 rotates along the motor shaft direction with the motor 41, and under the action of the elastic fixing component 7 set between the swing wheel 43 and the motor shaft, when the swing wheel 43 is driven by the motor 41, the swing wheel 43 slides along the motor shaft direction with the cooperation of the toggle part 42, that is, telescopic motion, so that a motor can not only drive the bracket to swing, but also realize telescopic motion during the swinging process.

[0042] In this embodiment, the shifting part 421 and the base 40 are separate components, but the base 40 and the shifting component can also be integrated as needed.

[0043] like Figure 4 As shown in FIG. 5 , the utility model also provides an embodiment of a massage device.

[0044] The massage device comprises an elastic massage body 5 fixed at one end to a fixing frame 2 or a bracket 1, and the other end of the elastic massage body 5 is received in a cavity formed by the bracket 1, and a telescopic swing transmission mechanism for driving the elastic massage body 5 to swing is provided at the bottom of the bracket 1. The elastic massage body 5 is provided with an opening (not shown in the drawings) and a massage channel (not shown in the drawings) connected to the opening, and an upper protective cover 6 is provided at the fixing frame 2 at the end where the elastic massage body is provided with the opening, and a lower protective cover 5 fixed to the fixing frame 2 is provided outside the telescopic swing transmission mechanism.

[0045] Specifically, the swing shaft 44 is not in the same straight line as the motor shaft, and an angle a is formed between the swing shaft 44 and the motor shaft, and the driving assembly 4 causes the bracket 1 fixed at one end to swing at the other end. The angle a formed between the swing shaft 43 and the motor shaft is an acute angle. The driving assembly 4 includes a motor 41 and a swing wheel 43 connected to the motor shaft 41, and a toggle 42 is provided between the swing wheel 43 and the motor 41. The motor 41 is fixed to the base 40 through a motor base 47, and the toggle 42 is fixed on the base 40. An elastic fixing assembly 7 that moves along the axial direction of the motor shaft is provided between the swing wheel 43 and the motor shaft. During operation, the swing wheel 43 rotates under the drive of the motor 41. Since there is a bevel fit between the swing wheel 43 and the moving member 42, the swing wheel 43 rotates while the toggle 42 causes the swing wheel 43 to move away from the motor along the motor shaft, that is, to telescopically move along the motor shaft. When the swing wheel 43 rotates, the swing shaft 44 on the swing wheel 43 drives one end of the bracket 1 to move. The elastic fixing assembly includes a fixing pin 71 fixed to the motor shaft and a spring 72 sleeved on the fixing pin 71 to move the swing wheel 43 toward the motor. The toggle member 42 includes a body 420 and a toggle portion 421 provided on the mating surface between the body 420 and the swing wheel to enable the swing wheel 43 to move telescopically along the motor shaft. The toggle portion 421 includes a protrusion 423 extending along the motor shaft.

[0046] In order to reduce resistance and noise, the side of the protrusion 423 is set as an inclined surface 422, and the inclined surface 422 cooperates with the elastic fixing component 7 to realize the extension movement of the swing wheel 43. The protrusion 423 can be set as multiple as needed. In this case, a groove 424 is set between adjacent protrusions 423. Multiple protrusions 423 are evenly distributed in annular shapes on a circle with the motor shaft as the center. When the body 421 is set as a circle, the protrusions 423 are evenly distributed on the radial edge of the body 421. In this way, the toggle member 42 is set to cooperate with the swing wheel 43, which can not only realize the swing movement of the bracket 1, but also realize the smooth and continuous telescopic movement of the bracket 1, and can also amplify the output torque of the motor, thereby avoiding the increase of the load on the motor due to the excessive resistance of the bracket during use, which affects the service life. The protrusion 423 and the groove 424 are smoothly connected, which can reduce the resistance between the swing wheel 43 and the toggle member 42, and also reduce noise. The bottom of the bracket 1 is provided with a bearing (not shown in the drawings) that cooperates with the swing shaft 44, which can reduce the frame momentum of the swing shaft 44 and the bracket 1, extend the service life, and reduce noise.

[0047] An elastic component 32 is provided between the bracket 1 and the fixing frame 2, which is partially retracted and stretched when the bracket 1 swings. The elastic component 32 is set as an annular structure, such as an annular silicone, or can be made of other materials to achieve partial retraction and stretching when the bracket swings. A fixing component 3 for fixing the elastic component 32 is provided between the bracket 1 and the fixing frame 2. The fixing component 3 includes a lower fixing sleeve 31 that is sleeved on the bracket 1 to fix the lower end of the elastic component 32 and an upper fixing sleeve 33 that directly or indirectly fixes the upper end of the elastic component 32 to the fixing seat 2. In order to improve the fixing effect, a fixing groove (not shown in the figure) is provided between the elastic component 32 and the bracket 1

[0048] When in use, the motor 41 drives the swing wheel 43 to rotate synchronously, and the swing shaft 44, which is not coaxial with the swing wheel 43, rotates with the swing wheel 43, which is coaxial with the motor shaft, as the shaft, driving one end of the bracket 1 to rotate, while the other end is connected to the fixing seat 2 by the elastic component 32 and does not rotate, so as to realize the swinging motion of one end of the bracket 1. At the same time, the rotating swing wheel 43 cooperates with the protrusion 423 and the groove 424 on the stationary toggle part 421, and the swing wheel 43 rotates along the motor shaft direction with the motor 41, and under the action of the elastic fixing component 7 set between the swing wheel 43 and the motor shaft, when the swing wheel 43 is driven by the motor 41, the swing wheel 43 slides along the motor shaft direction with the cooperation of the toggle part 42, that is, telescopic motion, so that a motor can not only drive the bracket to swing, but also realize telescopic motion during the swinging process.

[0049] Since it can realize swinging motion and telescopic motion during the swinging process, it can realize multiple motion combination and improve the user experience.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
