[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0035] refer to Figures 1 to 3 , Figure 1 This invention provides a three-dimensional illustration of a shoulder and neck integrated massage device according to an embodiment of the present invention. Figure 1 ; Figure 2 This invention provides a three-dimensional illustration of a shoulder and neck integrated massage device according to an embodiment of the present invention. Figure 2 ; Figure 2 This diagram shows a partial structural schematic of a shoulder and neck massage device provided in an embodiment of the present invention.

[0036] like Figures 1 to 3 As shown, the technical solution provided in this application is a shoulder and neck integrated massage device, including a housing 1, wherein the housing 1 includes a drive section 10 and a massage section 11. The massage sections 11 are respectively disposed on the drive section 10 along a first direction ( Figure 1 (as shown in the X direction) at both ends, and along the second direction ( Figure 1 Extending in the Y direction (as shown), it cooperates with the drive section 10 to form the neck area 12. The drive section 10 is equipped with a drive assembly, a transmission shaft 3 and a kneading assembly. The transmission shaft 3 extends in the first direction and is placed at both ends within the massage section 11.

[0037] The kneading components are symmetrically arranged on both sides of the drive component along the first direction, including a first eccentric wheel 40, a limiting cam 41, a swing seat 42, and a massage arm 43. The limiting cam 41 has an inclined surface on the side away from the drive component along the first direction, and the first eccentric wheel 40 is abutted against the inclined surface and is connected to the drive shaft 3 for transmission.

[0038] The base 42 is mounted on the first eccentric wheel 40, and a connecting rod 45 is provided at one end along the second direction. The connecting rod 45 extends from the side wall of the drive section 10 into the neck area 12 and is connected to the massage arm 43 so as to drive the transmission shaft 3 to rotate through the drive assembly, thereby causing the base 42 and the massage arm 43 to reciprocate within the neck area 12.

[0039] This application provides a shoulder and neck integrated massage device. The drive assembly drives the transmission shaft 3 to rotate. The first eccentric wheel 40 causes the swing seat 42 and massage arm 43 to reciprocate through its eccentric action. Since the plane in contact with the first eccentric wheel 40 is an inclined surface, the limiting cam 41 applies an unbalanced force to the first eccentric wheel 40 during rotation, which in turn causes the massage arm 43 to move in the first direction and the third direction. Figure 1 The varying heights (as shown in the Z-direction) make the neck massage more diverse and improve user comfort.

[0040] In some embodiments, reference Figures 1 to 3 The kneading assembly also includes a limiting assembly located on the side of the drive shaft 3 away from the neck section 12 along the second direction. The limiting assembly includes a rotating frame 50 and a sliding sleeve 51. The rotating frame 50 extends along the first direction and has connecting guide posts 72 at both ends. The sliding sleeve 51 is respectively fitted onto the connecting guide posts 72 at both ends and fixedly connected to the housing 1, allowing the rotating frame 50 to rotate relative to the sliding sleeve 51. A limiting rod 44 is provided at the other end of the swing seat 42 along the second direction, and the limiting rod 44 passes through the rotating frame 50.

[0041] For example, the limiting rod 44 swings with the swing of the massage arm 43. When the massage arm 43 moves in the first direction, the limiting rod 44 moves within the rotating frame 50. When the massage arm 43 moves in the third direction, the limiting rod 44 rotates together with the rotating frame 50. The cooperation between the limiting rod 44 and the rotating frame 50 enhances the stability of the kneading component during operation, ensuring that the massage arm 43 moves accurately on the preset path, thereby improving the precision and effect of the massage.

[0042] In some embodiments, reference Figures 1 to 3The drive assembly includes a gear module and a drive motor 21. The gear module includes a first gear 20 and a second gear. The first gear 20 is connected to the transmission shaft 3. The drive motor 21 is on the same side as the limiting assembly and is located close to the first gear 20. The second gear is connected to the drive end at the bottom of the drive motor 21. The tooth surface of the first gear 20 is inclined, and the second gear has a helical tooth surface that meshes with the first gear 20, which is used to drive the second gear through the drive motor 21, thereby causing the first gear 20 and the transmission shaft 3 to rotate.

[0043] For example, the gear module simplifies the complex mechanical structure of traditional massage devices, making the entire device more compact and space-saving. At the same time, the massage device has low power loss during operation, improving overall work efficiency.

[0044] In some embodiments, reference Figures 1 to 3 The massage section 11 is internally equipped with a clamping assembly, which includes a second eccentric wheel 60, a third eccentric wheel 61, a rear clamping arm 62, a front clamping arm 63, and massage balls 64. The second eccentric wheel 60 and the third eccentric wheel 61 are coaxially stacked and connected to the drive shaft 3. One end of the rear clamping arm 62 is rotatably connected to the second eccentric wheel 60, and the other end extends from the bottom of the massage section 11 along the second direction near the drive shaft 3. One end of the front clamping arm 63 is rotatably connected to the third eccentric wheel 61, and the other end extends from the bottom of the massage section 11 along the second direction away from the drive shaft 3, so that the second eccentric wheel 60 and the third eccentric wheel 61 respectively drive the rear clamping arm 62 and the front clamping arm 63 to reciprocate back and forth. The massage balls 64 are respectively located at the bottom of the rear clamping arm 62 and the bottom of the front clamping arm 63.

[0045] For example, by coaxially stacking the second eccentric wheel 60 and the third eccentric wheel 61, and by driving the transmission link with the transmission shaft 3, the coordinated work of the front and rear clamping arms 62 is realized, simulating the pinching action of a human hand, thus improving the realism and effect of the massage.

[0046] In some embodiments, reference Figures 1 to 3 The clamping assembly also includes a guide assembly, which includes a fixing frame 70 and a connector 71.

The connecting guide post 72 passes through the limiting waist hole 73 and is placed inside the fixing frame 70.

[0047] For example, the connection and fixation between the fixed frame 70 and the housing 1, as well as the design of the limiting waist hole 73 of the front clamping arm 63, enhance the stability and precision of the clamping assembly during the massage process, allowing the front clamping arm 63 and the rear clamping arm 62 to perform reciprocating movements, simulating a more natural clamping action, improving the adaptability and flexibility of the massage device, and reducing the shaking of the front clamping arm 63 during the sliding process, thereby improving the sliding efficiency.

[0048] In some embodiments, reference Figures 1 to 3 The bottom of the housing 1 is provided with multiple clearance grooves 13, which are correspondingly provided with the rear clamping arm 62 and the front clamping arm 63. Each clearance groove 13 extends along the second direction and is used to guide and limit the reciprocating motion of the rear clamping arm 62 and the front clamping arm 63.

[0049] For example, the clearance groove 13 is provided correspondingly to the rear clamping arm 62 and the front clamping arm 63, which can more accurately guide and limit the back-and-forth reciprocating motion of the rear clamping arm 62 and the front clamping arm 63, thereby improving the accuracy and stability of the assembly.

[0050] In some embodiments, reference Figures 1 to 3 Both ends of the drive shaft 3 are provided with rotating bearings 30 and bearing seats 31. The rotating bearings 30 are located between the first eccentric wheel 40 and the second eccentric wheel 60 and are sleeved on the drive shaft 3. The bearing seats 31 are sleeved on the outside of the rotating bearings 30 and are connected and fixed to the housing 1.

[0051] For example, both ends of the drive shaft 3 are provided with rotating bearings 30 and bearing seats 31, which can provide more stable support, reduce shaft vibration and sway, and improve the stability and reliability of the entire system.

[0052] In some embodiments, reference Figures 1 to 3 The drive assembly also includes a rechargeable battery 22, which is disposed on both sides of the drive motor 21 along the first direction and is electrically connected to the drive motor 21.

[0053] For example, by arranging the rechargeable battery 22 on both sides of the drive motor 21, space can be utilized more effectively, which helps to improve the overall compactness of the device and balance the weight distribution of the device.

[0054] In some embodiments, reference Figures 1 to 3 The massage device also includes a PCB control board assembly 14, which is located on one side of the housing 1 along the first direction and is connected to the drive motor 21 and the rechargeable battery 22. The PCB control board assembly 14 includes a charging socket 140 and a plurality of adjustment buttons 141. The charging socket 140 is used to charge the rechargeable battery 22, and the plurality of adjustment buttons 141 are used to adjust the speed of the drive motor 21.

[0055] For example, the integrated design of the PCB control board assembly 14 can simplify the internal structure of the massage device, making the control more centralized and efficient, allowing users to easily charge and adjust the speed of the drive motor 21, thus improving the ease of operation.

[0056] In some embodiments, reference Figures 1 to 3 The massage device also includes an auxiliary strap.
