Technical Field

[0001] The invention relates to the technical field of automatic equipment, and in particular to a multi-purpose motor magnetic woven screw telescopic transmission mechanism and a bracket thereof. Background Art

[0002] In the design of personal massage equipment, traditional transmission mechanisms mostly use brushed motors and gear boxes to achieve reciprocating motion. Although this type of design can meet basic functional requirements, it has some shortcomings in practical applications: 1. Wear and noise: Traditional brushed motors have contact friction between the brushes and the commutator, which will produce loud noise after long-term use, and the brushes will gradually wear, affecting the performance and life of the motor.

[0003] 2. Low positioning accuracy: Traditional mechanical travel limit devices are difficult to provide accurate position feedback, resulting in the inability to accurately control the telescopic length of the equipment during operation, affecting the user experience.

[0004] 3. High structural complexity: Due to the need for additional gearboxes and other auxiliary components, the structure of the entire system becomes more complicated, which not only increases the manufacturing cost but also increases the difficulty of maintenance.

[0005] 4. Safety issues: The screw drive mechanism in the traditional design lacks an effective buffer mechanism. When moving quickly, it may hit the end face of the motor shaft due to inertia, causing damage to the motor.
