Description

Technical Field

[0001] This invention relates to the field of massage equipment, specifically a displacement massage mechanism. Background Technology

[0002] Most massage mechanisms currently on the market use fixed roller structures, multiple rows of rollers, or a combination of back-and-forth rocking mechanisms to achieve localized massage. However, existing massage mechanisms have significant shortcomings, such as fixed massage positions, limited range of motion, single massage area, and inability to move back and forth relative to the user. In addition, due to the large differences in user body shapes, fixed or rocking mechanisms are difficult to adapt to different users, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a displacement massage mechanism, which has a simple structure, reliable operation, wide massage range, and can realize the forward and backward displacement of the massage components, thus having good applicability.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A displacement massage mechanism, comprising:

[0006] The mounting bracket has guide grooves extending forward and backward on both its left and right sides;

[0007] The rotating shaft extends to the left and right, with its two ends passing through the two guide grooves respectively;

[0008] The drive mechanism, installed in the middle of the rotating shaft, is used to drive the rotating shaft to rotate;

[0009] Several massage components are fixed on the rotating shaft and are located on the left and right sides of the drive mechanism.

[0010] Two linkage mechanisms are respectively located at both ends of the rotating shaft, which are used to drive the rotating shaft to move back and forth along the guide groove;

[0011] The linkage mechanism includes a transmission arm and a rotating arm. One end of the transmission arm is fixedly sleeved on the end of the rotating shaft, and one end of the rotating arm is rotatably connected to the corresponding side wall of the mounting frame. The other end of the transmission arm is hinged to the other end of the rotating arm.

[0012] Compared with the prior art, the advantages of the present invention are as follows:

[0013] 1. Through the cooperation of the transmission arm, the rotating arm and the guide groove, the rotating shaft can move back and forth along the guide groove under the drive mechanism, thereby making the massage component move back and forth with the rotating shaft, improving the massage coverage and massage experience;

[0014] 2. The cooperation between the guide rod and the guide sleeve effectively guides the drive mechanism during displacement, ensuring the reliability of the drive mechanism and improving the massage stability of the invention. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-4 The diagram shown is a schematic representation of an embodiment of a displacement-type massage mechanism provided by the present invention:

[0022] A displacement massage mechanism, comprising:

[0023] Mounting bracket 1 has guide grooves 2 extending forward and backward on both its left and right sides;

[0024] The rotating shaft 3 extends to the left and right, with its two ends passing through the two guide grooves 2 respectively;

[0025] The drive mechanism is installed in the middle of the rotating shaft 3 and is used to drive the rotating shaft 3 to rotate;

[0026] Several massage components 5 are fixed on the rotating shaft 3 and are respectively located on the left and right sides of the drive mechanism;

[0027] Two linkage mechanisms are respectively located at both ends of the rotating shaft 3, which are used to drive the rotating shaft 3 to move back and forth along the guide groove 2;

[0028] The linkage mechanism includes a transmission arm 61 and a rotating arm 62. One end of the transmission arm 61 is fixedly sleeved on the end of the rotating shaft 3, and one end of the rotating arm 62 is rotatably connected to the corresponding side wall of the mounting frame 1. The other end of the transmission arm 61 is hinged to the other end of the rotating arm 62.

[0029] The drive mechanism 4 includes a motor 41 and a worm gear 42. The worm gear 42 is fixedly sleeved on the rotating shaft 3, and a worm 43 that meshes with the worm gear 42 is fixedly mounted on the output shaft of the motor 41.

[0030] Two guide rods 7 are fixed on the mounting frame 1. The two guide rods 7 are arranged at a left-right interval and are parallel to the guide groove 2.

[0031] The outer side of the worm gear 42 is provided with a protective shell 44, and guide sleeves 45 are fixed on both the left and right sides of the protective shell 44. The two guide sleeves 45 correspond one-to-one with the two guide rods 7, and the guide sleeves 45 and guide rods 7 are slidably engaged.

[0032] The protective shell 44 has a through hole for the rotating shaft 3 to pass through, and the motor 41 is fixed to the protective shell 44.

[0033] The massage component 5 includes a bushing 51 and two roller groups. The bushing 51 is fixedly sleeved on the rotating shaft 3, and the two roller groups are arranged on the bushing 51 with a left-right interval.

[0034] The roller assembly includes a fixing plate 52, a cover 53, and several columns 54. The fixing plate 52 is fixedly connected to the outer peripheral wall of the bushing 51. The several columns 54 are arranged in a circular array. One end of each column 54 is fixedly connected to the fixing plate 52, and the other end is detachably connected to the cover 53. Rollers 55 are fitted on the columns 54 to rotate with them.

[0035] The fixing plates 52 in the two roller assemblies are arranged opposite to each other.

[0036] Furthermore, such as Figure 4 As shown, in order to protect the massage component 5, protective covers 8 are fixed on the top left and right sides of the mounting bracket 1. The protective covers 8 are provided with several front-to-back extending receiving grooves 81 corresponding to the massage component 5. Specifically, the top of the massage component 5 is exposed on the top side of the receiving grooves 81, making it easier for the massage component 5 to contact the user's massage area.

[0037] The working principle of this invention is roughly as follows:

[0038] When motor 41 starts, its output shaft drives worm gear 43 to rotate, which in turn drives worm wheel 42 to rotate rotating shaft 3. This causes the massage component 5, fixed on rotating shaft 3, to rotate synchronously. Simultaneously, through the cooperation of transmission arm 61, rotating arm 62, and guide groove 2, rotating shaft 3 moves back and forth along guide groove 2 under the drive of drive mechanism 4. This causes massage component 5 to move back and forth with rotating shaft 3, expanding the massage coverage area. Furthermore, the sliding cooperation between guide rod 7 and guide sleeve 45 effectively guides drive mechanism 4 during displacement, ensuring overall operational stability and enhancing the massage experience.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
