Description

Technical Field

[0001] The invention relates to the technical field of transmission mechanisms, and in particular to a servo synchronous belt reciprocating sliding structure. Background Art

[0002] The traditional reciprocating sliding structure usually uses a servo motor and a synchronous belt to achieve the linear motion of the moving parts; this structure is widely used in various occasions that require precise control of displacement and speed, such as industrial automation equipment, medical devices, and personal care products; however, in specific application scenarios, such as the products involved in the present invention (such as masturbation cups), the traditional structure may not be able to fully meet the higher requirements in terms of space limitations, operating noise, operating comfort and safety.

[0003] Disadvantages of existing technology 1. Assembly complexity and cost: Traditional servo synchronous belt reciprocating sliding structures often require complex assembly processes, which not only increases manufacturing costs, but also may cause assembly errors that affect the performance of the final product. In addition, the encoders or sensors that may be used in traditional designs are relatively expensive, increasing the overall cost.

[0004] 2. Friction and wear problems: Traditional systems using brushed motors have friction between mechanical contact parts. Long-term operation will cause wear, increase maintenance difficulty, and may generate sparks, posing a safety hazard.

[0005] 3. Noise and vibration: Due to the design characteristics of traditional structures, it is easy to generate loud noise and vibration during operation, especially at high speeds, which has a negative impact on the user experience.

[0006] 4. Inconvenient adjustment of the synchronous belt: In traditional designs, it is difficult to fine-tune the length of the synchronous belt. If the synchronous belt is too loose or too tight, it will affect the transmission efficiency and stability, and even cause the synchronous belt to slip or break.

[0007] Therefore, the prior art has deficiencies and needs further improvement. Summary of the invention

[0022] 4. Reduce noise and vibration: By suspending the tail of the driving gear box, the vibration generated during the operation of the machine is effectively reduced, and the working noise is significantly reduced, which improves the user experience.

[0023] 5. Precise position control: The position detection method combining Hall elements and magnets can accurately determine the travel limit of moving parts (such as TPE cups), ensuring the accuracy and stability of the telescopic action.

[0024] 6. Effective temperature management: The introduction of components such as thermal insulation gaskets, thermal insulation skins and temperature sensors effectively blocks the heat generated during the operation of the motor from being transferred to other components, prevents plastic deformation and other structural problems caused by high temperature, and ensures the safe and reliable operation of the entire machine.

The first magnet 12 encounters the first Hall element 14 and the second Hall element 15 during the reciprocating motion, thereby determining the positions of the two ends of the arrangement.

[0034] A PCB bracket 16 is also provided at the tail end of the driving motor 1; A second magnet 17 is also installed at the tail end of the rotating shaft of the driving motor 1, a gear box driving PCB board 18 is installed on the PCB bracket 16, and a third Hall element 19 is installed on the gear box driving PCB board 18.

[0039] Working principle of the present invention: The present invention describes a servo synchronous belt 5 reciprocating sliding structure, and its working principle can be summarized as the following steps: Power Transmission: After the driving motor 1 is started, it is decelerated and torque-increased through the driving gear box 2 connected thereto, thereby driving the driving wheel 3 installed on the driving gear box 2 to rotate.

[0040] The rotation of the driving wheel 3 causes the synchronous belt 5 wound on it and the driven wheel 4 to move accordingly. The movement of the synchronous belt 5 directly drives the moving part (TPE cup body 6) installed thereon to perform reciprocating telescopic movement along the set path.

[0041] Moving parts guide: Optical axis guide rails 7 are provided on both sides of the TPE cup body 6 to ensure that the cup body can move back and forth smoothly along a straight line to prevent deviation or jamming caused by the transmission of the synchronous belt 5.

[0043] The first magnet 12 on the cup body moves with the movement of the cup body. When it passes through the first Hall element 14 and the second Hall element 15 on the Hall PCB board 13 fixed on the side of the synchronous belt 5, a signal is generated and fed back to the control system to determine the front and rear ends of the stroke of the TPE cup body 6 and complete the longest stroke calibration.

[0044] The second magnet 17 installed at the rear end of the shaft of the driving motor 1 cooperates with the third Hall element 19 on the PCB bracket 16 to detect the specific number of rotations of the driving motor 1, thereby accurately controlling the telescopic distance of the TPE cup body 6.

[0045] Temperature monitoring: The temperature sensor arranged on the side of the outer wall of the drive motor 1 monitors the motor operating temperature in real time. Once the temperature exceeds the preset value, the system will take corresponding measures, such as adjusting the motor speed or suspending operation, to protect the motor and other components from high temperature damage.

[0046] Synchronous belt 5 tension adjustment: The bracket where the driven wheel 4 is located is designed with an annular hole 23, which allows the user to fine-tune the position of the driven wheel 4 according to actual conditions, ensuring that the synchronous belt 5 maintains appropriate tension to avoid adverse effects caused by being too loose or too tight.

The user can select different modes by pressing buttons, and the PCB main control board 24 sends instructions to the tooth box drive PCB board 18, and the brushless motor controls the rotation angle and number of turns of the tooth box according to the set parameters to achieve a variety of telescopic modes.
