[0032] The knee joint bears the weight of the entire body, and many people suffer knee damage due to injury, overexertion, or certain diseases. The most common symptoms are pain and reduced mobility. Additionally, dampness can impair blood circulation in the knee, causing inflammation and pain. Actually, there are several acupoints in the popliteal fossa (the area behind the knee). Stimulating these acupoints through tapping and kneading can significantly improve knee muscle relaxation and pain relief. However, most existing massage chairs primarily target the shoulders, neck, back, buttocks, and legs, and no specific massage devices have been developed for the knees.

[0033] To address the aforementioned technical problems, this application provides a leg massage device.

[0034] Reference Figure 1 , Figure 2 As shown, this application provides a leg massage device, including: a base 10, two linked swing arms 20, a first massage element 30 and a second massage element 40;

The second side plates 121 on both sides of the second open end 122 are provided with second through holes 123, and the sides of the two second side plates 121 away from the second open end 122 are provided with second bearings 125. The two ends of the second shaft 42 are rotatably connected to the second bearings 125 respectively. A bolt 124 is used to pass through the first through hole 113 and the second through hole 123, so that the first housing 11 and the second housing 12 are rotatably connected, and the included angle between the first housing 11 and the second housing 12 can be adjusted.

[0036] A drive motor 13 is located near the center of the base 10. Drive shafts 131 are located on both sides of the drive motor 13. Drive blocks 14 are sleeved on the drive shafts 131. Eccentric shafts 141 parallel to the drive shafts 131 are provided on the drive blocks 14. One end of the linkage arm 20 is a drive end 21, and the other end is a passive end 22 with a linkage shaft 221. The two drive ends 21 are rotatably connected to the eccentric shafts 141 on both sides of the drive motor 13 through mounting holes 211. A massage unit 23 is located above the drive end 21. The two passive ends 22 extend away from the center of the base 10. The massage unit 23 includes a base plate 231 and a plurality of massage bodies 232 arranged side by side on the base plate 231.

[0037] The first massage element 30 has a first block 31 at both ends of its bottom. A first shaft 32 is passed through the first block 31 and is sway-connected to one side of the base 10. The first block 31 has a first connecting hole 311 that is rotatably connected to a connecting shaft 221. The second massage element 40 has a second block 41 at both ends of its bottom.

The second block 41 has a second connecting hole 411 that is rotatably connected to another connecting shaft 221. The drive motor 13 drives the first massage element 30 and the second massage element 40 to swing back and forth through two connecting swing arms 20 respectively.

[0038] The upper surface of the first massage component 30 is provided with two sets of first supports 33; each set of first supports 33 is equipped with a first massage roller 34, the first massage roller 34 includes two first large rollers 341 and two first small rollers 342 disposed between the two first large rollers 341.

[0039] The upper surface of the second massage component 40 is provided with two sets of second brackets 43. Each set of second brackets 43 is equipped with a second massage roller 44. The second massage roller 44 includes two second large rollers 441 and two second small rollers 442 disposed between the two second large rollers 441.

[0040] This application provides a leg massage device, comprising: a base 10, a first massage element 30, a second massage element 40, and two linked swing arms 20; the two linked swing arms 20 are driven by a drive motor 13, which simultaneously drives the first massage element 30 and the second massage element 40 to massage the thigh and calf. This application also includes a massage unit 23 positioned above the two linked swing arms 20, allowing the massage unit 23 to massage and relieve pressure on the popliteal fossa area under the influence of the linked swing arms 20. This helps to improve blood circulation in the knee, relax the knee joint, and alleviate knee pain, further achieving the purpose of knee maintenance and enhancing the functionality of the leg massage device.

[0041] Reference Figure 2 , Figure 3 , Figure 4As shown, in this embodiment of the application, the first opening end 112 of the first housing 11 is opposite to the second opening end 122 of the second housing 12, and the first through hole 113 and the second through hole 123 are connected in series by a shaft bolt 124, so that the first housing 11 and the second housing 12 can be rotatably connected to achieve angle adjustment.

[0042] In this embodiment of the application, a drive motor 13 is installed at the center of the first opening end 112 of the first housing 11, and then the drive motor 13 is installed at the center of the base 10. Two linked swing arms 20 are respectively connected to the eccentric shaft 141 of the drive block 14 through the mounting holes 211 of the drive end 21, and are then installed on the two drive shafts 131 on the left and right sides of the drive motor 13 through the two drive blocks 14, and the passive ends 22 of the two linked swing arms 20 extend to the front and rear sides of the drive motor 13 respectively.

[0043] Further explanation: The passive end 22 of one linkage arm 20 is located within the first housing 11, while the passive end 22 of the other linkage arm 20 is located within the second housing 12. The first massage element 30 is oscillatingly mounted between two first bearings 114 of the first housing 11 via a first shaft 32, and is rotatably connected to the first connecting hole 311 of the first block 31 with the connecting shaft 221 of one of the linkage arms 20. The second massage element 40 is oscillatingly mounted between two second bearings 125 of the second housing 12 via a second shaft 42, and is rotatably connected to the second connecting hole 411 of the second block 41 with the connecting shaft 221 of the other linkage arm 20. By linking the first massage element 30 and the second massage element 40 to the two linkage arms 20 respectively, the drive motor 13 enables the two linkage arms 20, the first massage element 30, and the second massage element 40 to move synchronously, allowing the leg massage mechanism to simultaneously massage the user's thighs, calves, and back of the knees.

[0044] Reference Figure 5 , Figure 6 , Figure 7 as well as Figure 8As shown, when using the leg massage device, the first housing 11 and the second housing 12 of the base 10 are laid flat on a surface such as the ground, sofa, or bed, so that the user's legs can be naturally placed on the leg massage device. In this embodiment, the thigh rests against the second massage member 40. At the same time, the calf rests against the first massage member 30, and the back of the knee between the thigh and the calf rests against the massage unit 23 of the two linked swing arms 20. When the drive motor 13 is activated, the drive ends 21 of the two linked swing arms 20 are driven by the eccentric shafts 141 of the two drive blocks 14 to generate a circular lifting motion, thereby using the massage unit 23 to knead and massage the back of the knee. When the drive ends 21 of the two linked swing arms 20 move in a circle, the passive ends 22 of the two linked swing arms 20 simultaneously move back and forth. Then, the linkage shaft 221 of the passive end 22 pulls and drives the first massage member 30 and the second massage member 40 to move, so that the first massage member 30 can swing back and forth around the first shaft 32 as the axis, and at the same time use the first massage roller 34 to massage the calf. The second massage member 40 swings back and forth around the second shaft 42 as the axis, and at the same time uses the second massage roller 44 to massage the thigh, thereby achieving the leg massage effect of both back of the knee and massage.

[0045] Furthermore, the leg massage device can interchange the positions of the first massage element 30 and the second massage element 40 by changing the direction of the base 10, that is, the first massage element 30 massages the thigh, while the second massage element 40 massages the calf, so as to have different massage effects.

[0046] Reference Figure 9 , Figure 10 as well as Figure 11 As shown, this application also provides another implementation method.

[0047] In this embodiment, the angle between the first housing 11 and the second housing 12 of the base 10 is adjusted using a pivot bolt 124, so that the first housing 11 and the second housing 12 have a certain preset angle. The base 10 can be placed at the preset angle on the front edge of a chair such as a recliner or sofa. In this embodiment, the second housing 12 can be placed flat on the chair seat, and the first housing 11 extends downward along the front edge of the chair seat. When the user sits on the chair, their thighs will rest against the second massage member 40 of the second housing 12, their calves will hang down naturally and rest against the first massage member 30 of the first housing 11, and their knees will also rest against the massage unit 23 of the two linked swing arms 20. Thus, the leg massage device can provide massage effects for the thighs, calves, and knees, making the leg massager suitable for use in chairs, improving the practicality and convenience of the structure.

[0048] In this embodiment, a drive motor 13 drives two linked swing arms 20, which simultaneously drive the first massage element 30 and the second massage element 40 to massage the thigh and calf. A massage unit 23 is provided above the two linked swing arms 20, allowing the massage unit 23 to massage and relieve pressure on the back of the knee under the influence of the linked swing arms 20. This helps to improve blood circulation in the knee, relax the knee joint, and alleviate knee pain, further achieving the purpose of knee maintenance and enhancing the functionality of the leg massage device.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
