[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an electric flipping device for a massage chair helmet, including a massage chair body 1, a massage chair helmet 2 at the top of the massage chair body 1, and drive components 3 symmetrically arranged on the upper parts of the outer shells on both sides of the massage chair body 1 to drive the massage chair helmet 2 to rotate. The drive components 3 include a connecting plate 301, a rotating sleeve 302, and an electric push rod 303. One end of the connecting plate 301 is fixedly connected to the rotating sleeve 302, and the other end is rotatably connected to the output end of the electric push rod 303. The outer shell of the electric push rod 303 is rotatably connected to the massage chair body. The rotating sleeve 302 is rotatably mounted on the massage chair body 1. The massage chair helmet 2 is fixedly connected to the rotating sleeve 302. The extension and retraction of the output end of the electric push rod 303 will cause the connecting plate 301 to swing, thereby causing the rotating sleeve 302 to rotate and making the massage chair helmet 2 rotate.

[0026] In order to hide the drive component 3, the two outer shells on the top of the massage chair body 1 are provided with a hidden groove 4 for the drive component 3 to be installed. The massage chair body 1 is also provided with a decorative shell 5 for covering the hidden groove 4. The decorative shell 5 is fixed to the massage chair body 1. The two sides of the decorative shell 5 are provided with mounting holes 6 for the rotating sleeve 302 to pass through. The hidden groove 4 hides the drive component 3 well, and the decorative shell 5 effectively covers the hidden groove 4, achieving a good decorative effect.

[0027] Specifically, a fixed seat 7 is fixedly provided in the hidden groove 4, and the rotating sleeve 302 is rotatably set on the fixed seat 7. The outer end of the rotating fixed sleeve is also provided with a connecting shaft 8. The massage chair helmet 2 is provided with connecting protrusions 9 on both sides. The outer end of the connecting shaft 8 extends to the inner end face of the connecting protrusion 9 and forms a fixed connection. One end of the shaft is fixed to the rotating sleeve 302 by bolts, and the other end is fixed to the connecting protrusion 9 by bolts.

[0028] Specifically, one end of the hidden groove 4 extends upward with a notch 10, and the other end of the hidden groove 4 is provided with a hinge seat. The housing of the electric push rod 303 is rotatably connected to the hinge seat through a pin. By setting the notch 10, the area of ​​the hidden groove 4 can be reduced, making the overall structure design of the massage chair more regular.

[0029] Specifically, the top of the massage chair helmet 2 is equipped with an arc-shaped track 11 (see reference). Figure 3 The massage chair body 1 has an arc-shaped rod 12 on the back of its outer shell. One end of the arc-shaped rod 12 extends into the arc-shaped track 11 and forms a sliding connection with the arc-shaped track 11. The center of the arc-shaped rod 12 coincides with the axis of the rotating sleeve 302. When the massage chair helmet 2 rotates, the arc-shaped track 11 will slide relative to the arc-shaped rod 12. The arc-shaped track 11 has a balancing component 13 inside to balance the torque generated by the massage chair helmet 2 on the rotating sleeve 302. When the massage chair helmet 2 is fixed at a position where the center of gravity is not directly above the connecting shaft 8, it will generate torque on the connecting shaft 8. The balancing component 13 will balance the gravity of the massage chair helmet 2 that is biased to one side, thereby greatly offsetting the torque generated by the massage chair helmet 2 on the connecting shaft 8 and effectively protecting the electric push rod 303. It should be noted that the outer shell of the massage chair body 1 has an extension rod 14. One end of the arc-shaped rod 12 is fixed to the extension rod 14. The extension rod 14 can make the arc-shaped rod 12 fit in a suitable position with the arc-shaped track 11 without interfering with the decorative outer shell 5.

[0030] The balancing component 13 tilts the massage chair helmet 2 to one side by means of gravity: an arc-shaped groove 15 is provided inside the arc-shaped track 11, the center of the arc-shaped groove 15 coincides with the axis of the rotating sleeve 302. The balancing component 13 includes a balance plate 131, a spring 132, and a sliding plate 133. The balance plate 131 is fixed in the middle of the arc-shaped groove 15. Sliding plates 133 are slidably provided on both sides of the balance plate 131 inside the arc-shaped groove 15. An arc-shaped rod 12 passes through the balance plate 131 and forms a sliding connection with the balance plate 131. The spring 132 is sleeved on the arc-shaped rod 12 and is located between each set of sliding plates 133 and the balance plate 131. When the center of gravity of the massage chair helmet 2 is directly above the connecting shaft 8, the balance plate 131 is exactly directly above the connecting shaft 8. Figure 3 When the balance plate 131 is directly above the connecting shaft 8, and the massage chair helmet 2 rotates, if the balance plate 131 is not directly above the connecting shaft 8, it will compress the spring 132 that is biased to one side of the massage chair helmet 2. The spring 132 on the arc rod 12 will generate a counterforce on the massage chair helmet 2, thereby balancing the gravity generated by the bias of the massage chair helmet 2 to one side (the gravity on one side will be greater, thus generating a torque on the connecting shaft 8). It should be noted that the outer and inner ends of the sliding plate 133 of the massage chair helmet 2 are both set to fit the arc surface of the inner wall of the arc groove 15, making the sliding smoother.

[0031] In order to compress the spring 132 between the balance plate 131 and the slide plate 133 when the massage chair helmet 2 rotates, the two ends of the arc rod 12 in the length direction are provided with limiting arc grooves 15. The slide plates 133 on both sides of the balance plate 131 are provided with limiting blocks 17 that are slidably connected to the arc grooves 15. When the massage chair helmet 2 rotates and drives the balance plate 131 to compress the spring 132, the slide plate 133 on the side with the compressed spring 132 will not slide under the action of the limiting blocks 17 and the limiting arc grooves 15, while the slide plate 133 on the side with the uncompressed spring 132 will slide. This avoids the situation where the spring 132 on one side of the balance plate 131 is in a compressed state and the spring 132 on the other side is in a stretched state, which would cause the gravity to be unbalanced.

[0032] Specifically, multiple sets of sliding plates 133 are provided on both sides of the balance plate 131. All sets of sliding plates 133 are slidably connected to the arc-shaped rod 12. A spring 132 is provided between the sliding plates 133 on one side of the balance plate 131 and between the sliding plates 133 on the other side of the balance plate 131. This can prevent the massage chair helmet 2 from rotating too much, which would cause the deformation of a set of springs 132 to be too large. When multiple sets of sliding plates 133 are provided on one side of the balance plate 131, the sliding plates 133 furthest from the balance plate 131 on both sides are provided with limiting blocks 17 that are slidably connected to the arc-shaped groove 15. This allows the sliding plate 133 between the furthest sliding plate 133 and the balance plate 131 to compress the spring 132 to a certain extent, so that the lower sliding plate 133 can smoothly drive the lower sliding plate 133 to compress the spring 132 (if there are more than two sets of sliding plates 133 on one side of the balance plate 131, such as three or four sets, this embodiment uses two sets).

[0033] Specifically, multiple sets of arc-shaped tracks 11 are provided along the width direction of the massage chair helmet 2, and multiple sets of arc-shaped tracks 11 are provided on the back of the outer shell of the massage chair body 1. Each set of arc-shaped tracks 11 is provided with a balance component 13. This method can better distribute the balance force and avoid setting a single set of balance components 13, which would result in the spring 132 having an excessively thick diameter.

[0034] A specific application process of this embodiment is as follows:

[0035] The extension and retraction of the output end of the electric push rod 303 drives the connecting plate 301 to swing. The swing of the connecting plate 301 drives the rotating sleeve 302 to rotate. The rotation of the rotating sleeve 302 drives the massage chair helmet 2 to rotate through the connecting shaft 8. When the massage chair rotates to a position where the balance plate 131 is biased to one side directly above the connecting shaft 8, the balance plate 131 will compress the spring 132 whose center of gravity is biased to one side. Since the spring 132 and the slide plate 133 are both set on the arc rod 12, the deformation of the spring 132 will generate a reaction force on the balance plate 131, which can greatly counteract the gravity of the massage chair helmet 2 whose center of gravity is biased to one side, and greatly reduce the force of the electric push rod 303 to drive the massage chair helmet 2 to rotate or maintain a certain position.
