[0019] like Figures 1 to 5As shown, a telescopic motor with an upward and downward sliding ball bearing includes a motor 1, a telescopic mechanism 2, an upward and downward sliding ball bearing mechanism 3, and a vibration structure 4. One end of the telescopic mechanism 2 is connected to the motor 1, and the other end of the telescopic mechanism 2 is provided with a rotating shaft 5. The upward and downward sliding ball bearing mechanism 3 is fitted on the rotating shaft 5 and is driven by the telescopic mechanism 2 to rotate the rotating shaft 5. The upward and downward sliding ball bearing mechanism 3 includes a sliding ball shaft 30, a sliding ball sleeve 31, and a movable sliding ball assembly 32. The sliding ball shaft 30 is fitted on the rotating shaft 5, and a movable groove 33 is provided around the outer side of the sliding ball shaft 30. The sliding ball sleeve 31 is fitted on the outside of the sliding ball shaft 30, and one end of the sliding ball sleeve 31 is fastened to the telescopic mechanism 2. The sliding ball sleeve 31 is provided with a plurality of upward and downward sliding holes 34, which communicate with the movable groove 33. One end of the movable sliding ball assembly 32 passes through the upward and downward sliding holes 34 and is engaged in the movable groove 33.

[0020] like Figures 1 to 5 As shown, the movable groove 33 is wavy, and the movable groove 33 has multiple highest points and multiple lowest points.

[0021] like Figures 1 to 5 As shown, there is no limit to the number of the movable slots 33, that is, the number of movable slots 33 is one or more.

[0022] like Figures 1 to 5 As shown, there is no limit to the number of movable ball joints 32, that is, the number of movable ball joints 32 is one or more, and the number of movable ball joints 32 corresponds to the number of movable slots 33.

[0023] like Figures 1 to 5 As shown, the movable ball assembly 32 consists of several balls.

[0024] It should be noted that when the rotating shaft 5 rotates, it drives the sliding ball shaft 30 to rotate. With the cooperation of the sliding ball sleeve 31, the movable sliding ball group 32 and the sliding ball shaft 30, the movable sliding ball group 32 slides along the movable groove 33. At the same time, the movable sliding ball group 32 moves up and down along the upper and lower sliding holes 34 to realize the massage function of the upper and lower sliding balls.

[0025] like Figures 1 to 5 As shown, the output end of the motor 1 is provided with a rotating shaft 10, and one end of the rotating shaft 10 is connected to the telescopic mechanism 2.

[0026] It should be noted that the rotating shaft 10 drives the telescopic mechanism 2 to rotate and telescopic, which in turn drives the rotating shaft 5 to rotate. The rotating shaft 5 then drives the ball bearing shaft 30 to rotate. Under the limit of the ball bearing sleeve 31, the movable ball bearing assembly 32 moves along the movable groove 33, so that the movable ball bearing assembly 32 can slide up and down along the upper and lower sliding holes 34, forming the effect of up and down sliding balls.

[0027] like Figures 1 to 5 As shown, a reducer 11 is mounted on the upper end of the motor 1. This reducer 11 adopts existing technologies such as common planetary gear reducers, which will not be described in detail here. By setting the reducer 11, this utility model can achieve better deceleration function, thereby providing a smoother extension and retraction effect, suitable speed and lower noise, enhancing output stability, and having strong practicality.

[0028] like Figures 1 to 5 As shown, the structure of the vibrating head 41 includes a damping sleeve 40, a vibrating head 41, a weight 42, and a vibrator 43. The damping sleeve 40 is disposed outside the vibrating head 41, and the lower end of the damping sleeve 40 abuts against the ball bearing sleeve 31. The weight 42 and the vibrator 43 are both located inside the vibrating head 41. The output shaft of the vibrator 43 is connected to the weight 42, and the vibrator 43 is electrically connected to the motor 1.

[0029] It should be noted that the shock-absorbing sleeve 40 in this embodiment is made of a soft material, such as silicone. Its function is to buffer the vibration energy at the upper end when the vibrating head 41 vibrates, thereby preventing the energy from being directly transmitted to the lower end and improving the user experience. At the same time, the weight block 42 installed inside the vibrating head 41 can increase the overall weight of the vibrating head 41, enhance the vibration effect, and further improve the user experience.

[0030] like Figures 1 to 5 As shown, the telescopic mechanism 2 includes a sliding outer cylinder 20, a rotating inner cylinder 21, a telescopic shaft 22, and a connecting shaft 23 arranged sequentially from the outside to the inside. The connecting shaft 23 is fitted onto the outside of the rotating shaft 5. A pusher (not shown) is mounted on the rotating inner cylinder 21, and a pusher mounting hole 24 is provided on the rotating inner cylinder. One end of the pusher is fixed in the pusher mounting hole 24. In this embodiment, the pusher is a conventional component such as a pin.

[0031] It should be noted that the rotating shaft 10 is connected to the connecting shaft 23 and can drive the connecting shaft 23 to rotate, thereby enabling the telescopic rotating shaft 22 to rotate.

[0032] like Figures 1 to 5 As shown, the telescopic shaft 22 is provided with a spiral guide groove 25, and one end of the pusher is engaged in the spiral guide groove 25, allowing the pusher to move along the spiral guide groove 25. The pusher is in a fixed state.

[0033] like Figures 1 to 5As shown, the telescopic mechanism 2 also includes an upper fixed seat 26 and a rotating connecting seat 27. The upper fixed seat 26 is fastened between the ball sleeve 31 and the sliding outer cylinder 20. The rotating connecting seat 27 is movably disposed within the upper fixed seat 26. The upper end of the rotating connecting seat 27 is connected to the rotating shaft 5, and the lower end of the rotating connecting seat 27 is connected to the telescopic rotating shaft 22.

[0034] It should be noted that during use, the rotating inner cylinder 21 is in a fixed state. When the motor 1 drives the rotating shaft 10 to rotate, it drives the connecting shaft 23 to rotate. The rotation of the connecting shaft 23 in turn drives the telescopic rotating shaft 22 to rotate. The rotation of the telescopic rotating shaft 22 causes the rotating connecting seat 27 to rotate. The rotation of the rotating connecting seat 27 causes the rotating shaft 5 to rotate.

[0035] It should be further explained that when the rotating shaft 10 rotates, the rotating shaft 10 drives the connecting shaft 23 to rotate, and the connecting shaft 23 drives the telescopic rotating shaft 22 to rotate. The pushing member can slide along the spiral guide groove 25 of the telescopic rotating shaft 22. Since the pushing member is in a fixed state, the telescopic rotating shaft 22 can realize the movement of rotation and up and down. The sliding outer cylinder 20 moves up and down along the rotating inner cylinder 21, thereby driving the up and down sliding ball mechanism 3 to move up and down, realizing the telescopic function. With the cooperation of the rotating connecting seat 27, the rotating shaft 5, the sliding ball rotating shaft 30, the sliding ball sleeve 31 and the movable sliding ball group 32, the effect of up and down sliding ball is realized.

[0036] like Figures 1 to 5 As shown, the telescopic mechanism 2 also includes a lower fixed seat 28, the lower end of which is connected to the upper end of the motor 1. The telescopic shaft 22 is rotatably installed in the middle of the lower fixed seat 28, and the upper end of the lower fixed seat 28 is fastened to the lower end of the rotating inner cylinder 21.
