[0033] Reference Figures 1 to 6 In one embodiment of this utility model, a massage cushion includes:

[0034] The outer casing 100 has a motor bracket 111 and a bearing bracket 112 respectively installed on the inner walls of one end and the other end along its length.

[0035] A rotary motor 200 is mounted on the motor bracket 111. The rotary motor 200 has an output shaft 210, and a first eccentric counterweight 220 is fixed on the output shaft 210.

[0036] The bearing portion 300 is fixed to the bearing bracket 112;

[0037] A driven shaft 400 is mounted on the bearing part 300, and a second eccentric counterweight part 410 is fixed on the driven shaft 400;

[0038] A belt 500 is connected between the output shaft 210 and the driven shaft 400;

[0039] The power supply unit 600 is electrically connected to the rotary motor 200;

[0040] The controller 700 is electrically connected to the rotary motor 200.

[0041] In existing technologies, massage cushions typically use one or two motors to drive two rotating shafts with counterweights to achieve the vibration effect, which increases the complexity of the transmission structure.

[0042] In this invention, the outer shell 100 serves as the structural foundation of the entire massage cushion, and the material of the outer shell 100 can be metal or polymer. A cushioning layer (such as fabric or foam) is also provided around the outer shell 100. A motor bracket 111 and a bearing bracket 112 are respectively provided on the inner walls of one end and the other end along the length of the outer shell 100. The motor bracket 111 and the bearing bracket 112 can be mounted on the outer shell 100 or integrally formed.

[0043] A rotary motor 200 is mounted on the motor bracket 111. The rotary motor 200 has an output shaft 210. A first eccentric counterweight 220 is fixed on the output shaft 210. The rotary motor 200 drives the output shaft 210, thereby causing the first eccentric counterweight 220 on the output shaft 210 to vibrate.

[0044] The bearing portion 300 is fixed to the bearing bracket 112. For example, the bearing portion 300 includes an inner ring and an outer ring, with the inner ring rotatably supported by the outer ring, thereby forming a bearing structure.

[0045] The driven shaft 400 is mounted on the bearing portion 300, enabling it to rotate with low friction. A second eccentric counterweight 410 is fixed to the driven shaft 400, and this second eccentric counterweight 410 vibrates during the rotation of the driven shaft 400. Ultimately, the rotation of the first eccentric counterweight 220 and the second eccentric counterweight 410 together create the vibration effect. The specific arrangement of the first eccentric counterweight 220 and the second eccentric counterweight 410 can be varied to create a mass unevenness in the circumferential direction, thereby generating a vibration effect during rotation.

[0046] A belt 500 is connected between the output shaft 210 and the driven shaft 400. The type of belt 500 can be various, specifically designed to transmit the rotation of the output shaft 210 to the driven shaft 400.

[0047] The power supply unit 600 is electrically connected to the rotary motor 200. The power supply unit 600 can be connected to an external power cord or a battery for storing electricity.

[0048] The controller 700 is electrically connected to the rotary motor 200. The controller 700 controls the switching and rotation speed of the rotary motor 200. The controller 700 can be mounted on the housing 100 or connected externally via a cable.

[0049] In summary, by directly mounting the first eccentric counterweight 220 onto the output shaft 210 of the rotary motor 200, the overall mechanism is simplified; the driven shaft 400 is mounted on the bearing 300, and the belt 500 links the output shaft 210 and the driven shaft 400 together; the rotary motor 200 and the driven shaft 400 are positioned at opposite ends along the length, thereby creating a stable vibration effect.

[0050] Reference Figures 3 to 5 In one embodiment, the output shaft 210 passes through the rotary motor 200, and the first eccentric counterweight 220 includes two first sub-countershoulders 221, which are disposed at both ends of the output shaft 210 in the length direction.

[0051] In this embodiment, two first sub-counterweights 221 are set as the first sub-counterweights 221, thereby providing a more stable vibration effect during the rotation of the output shaft 210. The first sub-counterweights 221 can be fixed to the output shaft 210 by means of pin connection or the like.

[0052] Reference Figures 3 to 5 In one embodiment, the second eccentric counterweight 410 includes two second sub-countershoulders 411, which are disposed at both ends of the driven shaft 400 in the length direction.

[0053] In this embodiment, the second eccentric counterweight 410 is configured as two second sub-countersets 411, thereby providing a more stable vibration effect during the rotation of the driven shaft 400. The second sub-countersets 411 can be fixed to the driven shaft 400 by means of pins or the like.

[0054] Reference Figures 1 to 3 In one embodiment, the housing 100 includes an upper housing 110 and a lower housing 120 connected to each other, and the motor bracket 111 and the bearing bracket 112 are integrally formed on the upper housing 110 and the lower housing 120.

[0055] In this embodiment, to improve processing convenience, either the upper shell 110 or the lower shell 120 can be processed simultaneously during the integral molding of the upper shell 110 and the lower shell 120. The design of the mold facilitates the processing of the motor bracket 111 and the bearing bracket 112.

[0056] Reference Figure 1 In one embodiment, the outer surface of the upper shell 110 is provided with a protrusion 113 at the front and a recess 114 at the rear.

[0057] In this embodiment, the protrusions 113 and the recesses 114 can correspondingly enhance the effect of using the buttocks.

[0058] Reference Figures 3 to 6 In one embodiment, the bearing portion 300 includes two rotary bearings 310 that clamp the driven shaft 400 in the longitudinal direction.

[0059] In this embodiment, the bearing section 300 is configured as two rotary bearings 310, and the two rotary bearings 310 clamp the driven shaft 400 in the length direction, thereby fixing the driven shaft 400 in the length direction and avoiding abnormal movement in the length direction.

[0060] Reference Figure 1 In one embodiment, the power supply unit 600 is a battery.

[0061] In the foregoing embodiments, the type of power supply unit 600 is not limited; it can be a battery and / or an external power cord. In this embodiment, the power supply unit 600 is a battery, thereby increasing the flexibility of use of the massage cushion. Specifically, it can be a rechargeable battery, increasing ease of use.

[0062] In one embodiment, the power supply unit 600 is disposed at the other end of the housing 100 in the longitudinal direction.

[0063] In this embodiment, considering that the rotary motor 200 has a large mass and is prone to generating adverse abnormal vibrations during use, the power supply unit 600 is used as a counterweight to make the weight of the entire massage cushion more even.

[0064] Reference Figure 1 In one embodiment, a perforated hole 130 is provided through the center of the plane of the outer casing 100.

[0065] In this embodiment, the perforated holes 130 prevent the user's contact area from becoming too hot during use, thus improving the user experience.

[0066] In one embodiment, the belt 500 is a synchronous belt type.

[0067] In this embodiment, by limiting the type of belt 500, the rotational synchronization between the output shaft 210 and the driven shaft 400 is well achieved. Specifically, a toothed structure is provided on the driven shaft 400 at the position corresponding to the belt 500, a toothed structure is provided on the output shaft 210 at the position corresponding to the belt 500, and a toothed structure is provided on the inner circumference of the belt 500 itself, thereby forming a synchronous belt drive between the output shaft 210 and the driven shaft 400.

[0068] In summary, the massage cushion provided by this utility model simplifies the overall mechanism by directly mounting the first eccentric counterweight 220 onto the output shaft 210 of the rotary motor 200; the driven shaft 400 is mounted on the bearing part 300, and the belt 500 links the output shaft 210 and the driven shaft 400 together; the rotary motor 200 and the driven shaft 400 are positioned at both ends in the length direction, thereby creating a stable vibration effect.
