Description

Technical Field

[0001] The invention belongs to the technical field of vibration motors, in particular to a vibration motor for a massage chair. Background Art

[0002] The vibration motor used in massage chairs is a special motor that plays a vital role in massage chairs. A vibration motor, also called a vibration motor or exciter, is a motor that converts mechanical energy into electrical energy to produce a vibration effect. In massage chairs, vibration motors are often used to produce a vibration massage effect to help users relax their muscles and relieve fatigue. The vibration motor generates centrifugal force through the internal eccentric block or eccentric shaft when it rotates, causing the massage mechanism of the massage chair to vibrate. This vibration effect can stimulate muscles and nerves and promote blood circulation, thereby relaxing muscles and relieving fatigue; the vibration motor combined with other massage functions of the massage chair (such as kneading, tapping, etc.) can further enhance the massage effect; through vibration, muscle tissue can be stimulated more deeply, improving the comfort and effect of massage; the use of vibration motors can also enhance the overall user experience of the massage chair; it can not only provide users with more diverse massage methods, but also meet the needs and preferences of different users by adjusting the vibration frequency and intensity; however, the existing vibration motors for massage chairs themselves and the eccentric blocks at their transmission ends are usually installed and fixed with a large number of bolts, and a large number of bolts need to be tightened with the help of external tools during installation, which makes it inconvenient for operators to install during production and use, thereby reducing production and use efficiency.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When installing the eccentric block, the operator puts the connecting tube on the eccentric block onto the transmission shaft and inserts the three inserting strips into the three slots. Then the operator drives the fixing strip to rotate through the first hand wheel. When the fixing strip rotates, the shaft rod rotates inside the two shaft sleeves.

When the rotating rod rotates, the driven bevel gear is driven to rotate through the active bevel gear. When the driven bevel gear rotates, the threaded sleeve is driven to move downward through the threaded rod. When the threaded sleeve moves downward, the two pushing bars are driven to move downward through the two support bars. When the two pushing bars move downward, they both drive the slider to slide along the inside of the slide groove, which increases the stability of the two pushing bars when they move downward.

[0017] When the two pushing bars move downward, they push the two card blocks to move toward each other. When the two card blocks move toward each other, they drive the limit sleeve to slide along the surface of the limit rod and squeeze the telescopic spring at the same time, thereby ensuring the movement stability of the two card blocks while enabling them to have an elastic reset effect. When the two card blocks move toward each other, they are stuck in the inside of the two card slots for limiting, thereby quickly completing the fixed installation of the vibration motor body;

[0018] (3) The vibration motor body for the massage chair and the eccentric block at the output end thereof are very convenient to install, which reduces the workload of operators and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
