[0002] The automobile seat leg support is a device installed at the front end of the seat frame of a vehicle, used to support the lower legs of the occupant. Its function is to provide additional support and comfort to the legs of the occupant, so that the legs of the occupant can obtain better support and reduce the fatigue of the lower limbs.

[0003] With the progress of science and technology, people's requirements for the comfort of automobile seats are also constantly improving. Therefore, some seats have added leg massage functions, i.e., massage mechanisms are provided on the surface of the leg support to relieve the fatigue of the legs of the occupant and increase comfort. In the prior art, the massage mechanism provided on the surface of the leg support is usually an air bag massage mechanism. However, compared with mechanical massage mechanisms, the traditional air bag massage has obvious gaps in intensity and effect, and cannot relieve the fatigue of the rear side of the lower legs of the occupant. Therefore, the calf rear side massage mechanism provided on the leg support needs to be further optimized. SUMMARY

[0008] With the above structure, the drum component is eccentrically connected to the rotating shaft, and the driving mechanism drives the rotating shaft to rotate, which can drive the drum component to make circular motion around the center line of the rotating shaft. The massage protrusions on the drum component can intermittently protrude upward from the upper surface of the leg support main body, thereby performing mechanical rolling massage on the rear side of the lower legs of the user to achieve the effect of deeply relaxing the muscles of the lower legs and relieving fatigue.

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] like Figure 1 and 2 As shown, a calf massage device for a seat leg rest comprises a leg rest body 1, a rotating shaft 2 is rotatably mounted on the leg rest body 1, and a driving mechanism 3 for driving the rotating shaft 2 to rotate, wherein the rotating shaft 2 is arranged along the width direction of the leg rest body 1. In this embodiment, the orientation concept of the leg rest body 1 is based on the car seat, that is, the width direction of the leg rest body 1 corresponds to the width direction of the car seat. Figure 4It can be seen that the rotating shaft 2 is eccentrically connected with the roller part 4, and the circumferential surface of the roller part 4 is distributed with massage protrusions 41. The driving mechanism 3 drives the rotating shaft 2 to rotate, which can drive the roller part 4 to make a circular motion around the center line of the rotating shaft 2, so that the massage protrusions 41 on the roller part 4 can protrude upward intermittently on the upper surface of the leg supporting body 1, thereby mechanically rolling and massaging the back side of the user's lower leg, so as to achieve the effect of relaxing the lower leg muscles and relieving fatigue. When the massage function is not used, the roller part 4 is eccentrically rotated below the leg supporting body 1, and the massage protrusions 41 on the roller part 4 are all located below the leg supporting body 1. At this time, the upper surface of the leg supporting body 1 remains flat and does not interfere with the user's leg movement, so that the leg supporting function can be normally used, and the roller part 4 can also be protected to prevent the massage protrusions 41 on the roller part 4 from being damaged due to collision.

[0028] Based on the above structural design, by eccentrically connecting the roller part 4 on the rotating shaft 2, when in use, the driving mechanism 3 drives the rotating shaft 2 to rotate, which can drive the roller part 4 to make a circular motion around the center line of the rotating shaft 2, so that the massage protrusions 41 on the roller part 4 can protrude upward intermittently on the upper surface of the leg supporting body 1, thereby mechanically rolling and massaging the back side of the user's lower leg, so as to achieve the effect of relaxing the lower leg muscles and relieving fatigue. When the massage function is not used, the roller part 4 is eccentrically rotated below the leg supporting body 1, and the massage protrusions 41 on the roller part 4 are all located below the leg supporting body 1. At this time, the upper surface of the leg supporting body 1 remains flat and does not interfere with the user's leg movement, so that the leg supporting function can be normally used, and the roller part 4 can also be protected to prevent the massage protrusions 41 on the roller part 4 from being damaged due to collision.

[0029] Again, as shown in Figure 3 To improve the massage effect, in the present embodiment, the number of rotating shafts 2 is two groups, and the two groups of rotating shafts 2 are arranged along the width direction of the leg supporting body 1. The number of roller parts 4 is four groups, and the four groups of roller parts 4 are respectively connected at the four end positions of the two groups of rotating shafts 2, that is, the two roller parts 4 at the left end of the two groups of rotating shafts 2 are used for massaging the left lower leg of the user, and the two roller parts 4 at the right end of the two groups of rotating shafts 2 are used for massaging the right lower leg of the user.

[0030] Further, as shown in Figure 1 It can be seen that the leg supporting body 1 is provided with openings 11 corresponding to the positions of the roller parts 4, so that the massage protrusions 41 on the roller parts 4 can better act on the back side of the user's lower leg. In the present embodiment, two openings 11 are provided, and the two openings 11 correspond to the left two groups of roller parts 4 and the right two groups of roller parts 4 respectively, and the two openings 11 are rectangular openings.

[0031] Please refer to Figure 2 and 4 The driving mechanism 3 includes a motor 31 assembled at the middle part of the lower side of the leg supporting body 1. The motor 31 has two output shafts a, and the two output shafts a correspond to the two groups of rotating shafts 2 one by one. The corresponding output shaft a and the rotating shaft 2 are power-connected through a transmission assembly 32. The motor 31 can drive the two groups of rotating shafts 2 to rotate synchronously through the transmission assembly 32.

[0032] Further, please refer to Figure 2 and 4The transmission assembly 32 comprises a first transmission gear 321 sleeved on the output shaft a and a second transmission gear 322 sleeved in the middle of the rotating shaft 2, and the second transmission gear 322 is engaged with the first transmission gear 321. The motor 31 drives the first transmission gear 321 on the output shaft a to rotate, that is, it can drive the corresponding second transmission gear 322 to rotate. The transmission modes of the two groups of rotating shafts 2 are the same, and details are not repeated here.

[0033] In the embodiment, the motor 31 is located between the two rotating shafts 2, the output shaft a of the motor 31 is located below the rotating shaft 2 and perpendicular to the rotating shaft 2, the first transmission gear 321 and the second transmission gear 322 are both helical gears, and the first transmission gear 321 and the corresponding second transmission gear 322 are staggered in space, forming a staggered helical gear transmission of the two shafts. By such design, compared with other gear transmission modes, such as coaxial gear transmission and belt gear transmission, the occupied space of the transmission components can be reduced, the overall structure of the device is more compact, and the device has the advantages of high transmission efficiency, good stability and long service life.

[0034] As shown in Figure 2 and Figure 3 , taking one of the left drum components 4 as an example, the second eccentric bracket 6 protrudes radially outward at the left end of the rotating shaft 2, and the drum component 4 is rotatably installed at the distal end of the second eccentric bracket 6. By such design, when the rotating shaft 2 rotates, it can drive the second eccentric bracket 6 to rotate, thereby driving the drum component 4 to revolve around the rotating shaft 2 and rotate around its own axis, further deepening the stimulation of the massage protrusions 41 to the muscles and improving the massage effect.

[0035] As shown in Figure 2 and 3 , the rotating shaft 2 is horizontally arranged in the middle of the leg support body 1, the support shaft 7 is rotatably installed on the left side of the leg support body 1 and coaxially opposite to the rotating shaft 2, the first eccentric bracket 5 protrudes radially outward on the support shaft 7, and the drum component 4 is rotatably connected to the first eccentric bracket 5 away from the second eccentric bracket 6. By such design, the stability of the drum component 4 in support and rotation can be ensured. On the same rotating shaft 2, the connection structure of the drum component 4 at the right end of the rotating shaft 2 is the same as that at the left end, and the two groups of rotating shafts 2 have the same structure, and details are not repeated here.

[0036] As shown in Figure 2 and 5 , the first mounting seat 8 extends downward and is fixedly assembled on the lower side of the leg support body 1, the first mounting seat 8 is provided with two first connecting through holes 81, the two first connecting through holes 81 are distributed along the length direction of the leg support body 1, and the two groups of rotating shafts 2 are respectively rotatably supported on the two first connecting through holes 81 through the first bearings c. In order to increase the stability of the support of the rotating shaft 2, in the embodiment, the first mounting seat 8 is provided with two groups.

[0037] As shown inFigure 2 and 5 The second mounting seat 9 is arranged on the lower side of the leg supporting body 1, and two second connecting through holes 91 are arranged on the second mounting seat 9. The left two supporting shafts 7 are rotatably supported in the two second connecting through holes 91 on the left second mounting seat 9 through the second bearing b. The right two supporting shafts 7 are arranged in the same manner.

Such changes fall within the scope of the present application.
