[0002] In contemporary society, cars are not only essential tools for travel but also a part of daily life. With the improvement of living standards, people have higher expectations for the comfort inside cars. Especially for occupants during long - term driving or riding, due to maintaining the same posture for a long time, it is easy to cause physical fatigue and muscle stiffness. To improve the comfort of vehicle seats, vehicle seats with massage functions have been introduced on the market to relieve the fatigue caused by long - term driving or riding of occupants.

[0041] The present utility model will be further described below in conjunction with the embodiments and the accompanying drawings.

[0042] As Figure 13 and 14As shown in the figure, an automotive seat includes a seat frame assembly F. A calf massage device is rotatably installed on the front side of the seat frame assembly F. This leg rest can massage both sides and the back side of the user's calves simultaneously, enabling the user's legs to be fully relaxed. The calf massage device will be described in detail below. In this embodiment, the orientation of the leg rest is referenced to the automotive seat, that is, the width direction of the leg rest corresponds to the width direction of the automotive seat.

[0043] As Figures 1 to 3 shown in the figure, a calf massage device includes a leg rest main body 1. A splint sleeve group A is movably installed on the leg rest main body 1, and this splint sleeve group A can be switched between a folded state and an unfolded state. A first driving mechanism B is also provided on the leg rest main body 1, which is used to drive the splint sleeve group A to switch between the folded state and the unfolded state. Combining Figure 3 and 4 , in the unfolded state, the splint sleeve group A can enclose two accommodating grooves a distributed left and right. The splint sleeve group A integrates massage components 2 in the side regions corresponding to the accommodating grooves a. When the user's calves are placed in the accommodating grooves a, the massage components 2 can massage both sides of the user's calves. In the folded state, the splint sleeve group A covers the surface of the leg rest main body 1 or is stored inside the leg rest main body 1.

[0044] Again, as Figure 3 and 4 shown in the figure, two groups of bottom massage mechanisms D are symmetrically arranged on the leg rest main body 1 along its width direction. When the splint sleeve group A is unfolded, the two groups of bottom massage mechanisms D are respectively exposed at the bottoms of the two accommodating grooves a, and the two groups of bottom massage mechanisms D are respectively used to massage the back sides of the two calves of the user.

[0045] Based on this, when the user uses the leg massage function, the first driving mechanism B drives the splint sleeve group A to unfold to the upper side of the leg rest main body 1 and enclose two accommodating grooves a. The user's calves can be placed in the two accommodating grooves a. The splint sleeve group A can clamp both sides of the two calves. The massage components 2 work, that is, they can massage both sides of the calves. At the same time, the bottom massage mechanisms D located at the bottoms of the two accommodating grooves a can respectively massage the back sides of the two calves, so as to be able to massage the user's calves in all directions and at multiple angles, achieving the purpose of fully relieving leg fatigue. When the leg massage function is not used, the splint sleeve group A can cover the surface of the leg rest main body 1 or be stored inside the leg rest main body 1, without occupying the foot space of the occupant, having the technical advantages of a compact, reasonable structure and good overall aesthetics.

[0046] Please refer to Figure 1 and 3, the splint set A includes a first splint A1, a second splint A2, a third splint A3, and a fourth splint A4 that are sequentially assembled in the width direction of the leg rest main body 1. All four splints can be flipped relative to the leg rest main body 1 and moved in the width direction. The first driving mechanism B can drive the four splints to flip and move relative to the leg rest main body 1. From Figure 7 and Figure 9 it can be seen that the massage component 2 is arranged on the upper surfaces of the four splints. When the four splints enclose two groups of receiving grooves a through movement and flipping, the massage components 2 on the first splint A1 and the second splint A2 can correspond to both sides of the left group of receiving grooves a, and the massage components 2 on the third splint A3 and the fourth splint A4 can correspond to both sides of the right group of receiving grooves a. Among them, the massage component 2 is a massage airbag or a mechanical massage component. In this embodiment, the massage component 2 is preferably a massage airbag. When the user's calves are placed in the two groups of receiving grooves a, the massage airbags are inflated and deflated cyclically, and can respectively perform clamping and kneading massages on both sides of the two calves.

[0047] Refer again Figure 6 and 7 , a first connecting rod 5 is provided between the first splint A1 and the leg rest main body 1. One end of the first connecting rod 5 is hinged to the lower side of the first splint A1, and the other end is hinged to the left end of the leg rest main body 1. The lower side of the first splint A1 is also the side of the first splint A1 that faces the leg rest main body 1 when it is folded. A second connecting rod 6 is provided between the fourth splint A4 and the leg rest main body 1. The connection principle of the second connecting rod 6 is the same as that of the first connecting rod 5, that is, one end of the second connecting rod 6 is hinged to the lower side of the fourth splint A4, and the other end is hinged to the right end of the leg rest main body 1. The second splint A2 and the third splint A3 are hinged to each other. Combining Figure 2 as shown, the first driving mechanism B includes a lead screw B1 rotatably arranged on the leg rest main body 1, four sliders B3 slidably arranged on the leg rest main body 1, and a first motor B2 for driving the lead screw B1 to rotate. Among them, the lead screw B1 extends along the width direction of the leg rest main body 1, and all four sliders B3 are threadedly sleeved on the lead screw B1. When the lead screw B1 rotates, two adjacent sliders B3 can move in opposite directions. To ensure the reliability and accuracy of the linear movement of the four sliders B3 and reduce the assembly and adjustment difficulty, the lead screw B1 is composed of a left section lead screw B1a and a right section lead screw B1b spliced coaxially. The left section lead screw B1a and the right section lead screw B1b are coaxially connected by a coupling B4 so that the left section lead screw B1a and the right section lead screw B1b can rotate synchronously.

[0048] Taking Figure 6For reference, the right end of the first clamping plate A1, the left end of the second clamping plate A2, the right end of the third clamping plate A3, and the left end of the fourth clamping plate A4 are respectively rotatably connected to four sliders B3. In the initial state, the two sliders B3 connected to the first clamping plate A1 and the second clamping plate A2 are located in the middle of the left section of the lead screw B1a, and the two sliders B3 connected to the third clamping plate A3 and the fourth clamping plate A4 are located in the middle of the right section of the lead screw B1b. Referring to Figure 7 As shown, when the lead screw B1 rotates, the two sliders B3 on the left section of the lead screw B1a move left and right respectively. The slider B3 moving left can drive the right end of the first clamping plate A1 to slide left. At this time, under the action of the first connecting rod 5, the first clamping plate A1 can rotate upward with the slider as the rotation fulcrum while moving. The slider B3 moving right on the left section of the lead screw B1a can drive the left end of the second clamping plate A2 to slide right. At this time, under the restraint of the third clamping plate A3, the second clamping plate A2 can rotate upward with the slider as the rotation fulcrum while moving. The first clamping plate A1 and the second clamping plate A2 enclose a receiving groove a. Similarly, when the lead screw B1 rotates, the two sliders B3 on the right section of the lead screw B1b can also move left and right respectively. The slider B3 moving left can drive the right end of the third clamping plate A3 to slide left. At this time, under the restraint of the second clamping plate A2, the third clamping plate A3 can rotate upward with the slider as the rotation fulcrum while moving. The slider B3 moving right on the right section of the lead screw B1b can drive the left end of the fourth clamping plate A4 to slide right. At this time, under the action of the second connecting rod 6, the fourth clamping plate A4 can rotate upward with the slider as the rotation fulcrum while moving. The third clamping plate A3 and the fourth clamping plate A4 enclose another receiving groove a.

[0049] Conversely, when the lead screw B1 rotates in the opposite direction, it can drive the four clamping plates to fold and cover the surface of the leg rest main body 1. The surfaces of the four clamping plates are kept flat, so that it is convenient for users to use it as a leg rest function. In addition, this structure will not interfere with the user's leg activities and can also take into account the overall aesthetics of the car seat.

[0050] Furthermore, as shown in Figure 2 and 7 the lead screw B1 is successively provided with a left-handed thread section c, a right-handed thread section d, a left-handed thread section c, and a right-handed thread section d along the axial direction, and each of the four sliders B3 corresponds to a section of thread. Designed in this way, it can achieve the movement of adjacent two sliders B3 in opposite directions.

[0051] Please refer to Figure 7 and 8 , upwardly extending connecting blocks B31 are fixedly provided on the inner sides of the four sliders B3. One ends of the first clamping plate A1, the second clamping plate A2, the third clamping plate A3, and the fourth clamping plate A4 are respectively rotatably connected to the corresponding connecting blocks B31 through rotating components b. Considering this way is for the convenience of assembly.

[0052] Refer to Figure 2and 8 , in this embodiment, there are two sets of lead screws B1. The two sets of lead screws B1 both extend along the width direction of the leg rest main body 1 and are distributed at both ends in the length direction of the bottom of the leg rest main body 1. The structures of the two sets of lead screws B1 are the same, and the sliders B3 on the two sets of lead screws B1 correspond one by one, that is, both ends of one side of each clamping plate are respectively rotatably connected with two sets of sliders B3, which will not be elaborated here. The first motor B2 is arranged at the right end of the leg rest main body 1. Combining Figure 5 and 6 shown, this first motor B2 has two first output shafts, and first gears B21 are assembled on both first output shafts. Second gears B11 are provided at the right ends of the two sets of lead screws B1, and the two second gears B11 are respectively meshed with the two first gears B21. In this embodiment, both the first gear B21 and the second gear B11 are helical gears, and the corresponding first gear B21 and second gear B11 are arranged staggeredly in space. Arranging the first motor B2 at the end and adopting helical gear transmission can reduce the occupied space of the first driving mechanism B, making the overall structure of the device more compact. At the same time, it also has the advantages of high transmission efficiency, good stability and long service life. In addition, arranging the two sets of lead screws B1 at both ends in the length direction of the bottom of the leg rest main body 1 can leave space in the middle of the leg rest main body 1 for facilitating the installation of the bottom massage mechanism D, having the technical advantages of compact and reasonable structural arrangement.

[0053] Another example Figure 2 and Figure 8 shown, mounting seats 11 are fixedly assembled at the end positions of the bottom of the leg rest main body 1 corresponding to the two sets of lead screws B1, and the four ends of the two sets of lead screws B1 are respectively rotatably supported in the corresponding mounting seats 11. Combining Figure 3 shown, the number of the first connecting rods 5 is two sets. One ends of the two sets of first connecting rods 5 are respectively hinged on the left two mounting seats 11, and the other ends are respectively hinged on both ends of the lower side of the first clamping plate A1. Similarly, one ends of the two sets of second connecting rods 6 are respectively hinged on the right two mounting seats 11.

[0054] Please refer Figure 2 and 4 , a rotating shaft 3 extending along the width direction of the leg rest main body 1 and a second driving mechanism E for driving the rotating shaft 3 to rotate are provided on the lower side of the leg rest main body 1. In this embodiment, the bottom massage mechanism D is a roller component, which is composed of Figure 11It can be seen that massage protrusions D1 are distributed on the circumferential surface of the roller member. Two groups of bottom massage mechanisms D are eccentrically rotationally connected to both ends of the rotating shaft 3. When the splint sleeve group A is unfolded, the left and right groups of bottom massage mechanisms D respectively correspond to the bottoms of the left and right groups of receiving grooves a. The second driving mechanism E drives the rotating shaft 3 to rotate, which can drive the two groups of roller members to make a circular motion around the center line of the rotating shaft 3. The massage protrusions D1 on the bottom massage mechanism D can intermittently protrude upward from the upper surface of the leg support main body 1, so as to perform mechanical rolling massage on the back side of the user's calf, so as to achieve the effect of deeply relaxing the calf muscles and relieving fatigue. When the massage function is not used, the bottom massage mechanism D eccentrically rotates to the lower side of the leg support main body 1, and the massage protrusions D1 on the bottom massage mechanism D are all located on the lower side of the leg support main body 1. At this time, the upper surface of the leg support main body 1 is kept flat, so as to facilitate folding the splint sleeve group A onto the surface of the leg support main body 1. In addition, it can also protect the bottom massage mechanism D and prevent the massage protrusions D1 on the bottom massage mechanism D from being damaged due to collision.

[0055] Referring again Figure 2 , to improve the massage effect, in this embodiment, the number of the rotating shafts 3 is two groups, and the two groups of rotating shafts 3 are both arranged along the width direction of the leg support main body 1. The total number of the bottom massage mechanisms D is four groups, and the four groups of bottom massage mechanisms D are respectively connected to the four end positions of the two groups of rotating shafts 3, that is, the two bottom massage mechanisms D at the left end of the two groups of rotating shafts 3 are used to massage the left calf of the user, and the two bottom massage mechanisms D at the right end of the two groups of rotating shafts 3 are used to massage the right calf of the user.

[0056] Furthermore, Figure 4 It can be seen that openings 12 are provided at the positions of the leg support main body 1 corresponding to the bottom massage mechanisms D, so that the massage protrusions D1 on the bottom massage mechanisms D can better act on the back side of the user's calf. In this embodiment, there are two openings 12, and the two openings 12 respectively correspond to the two groups of bottom massage mechanisms D on the left side and the two groups of bottom massage mechanisms D on the right side, and the two openings 12 are both rectangular openings.

[0057] As Figure 10 and 12 shown, the second driving mechanism E includes a second motor E1 assembled in the middle of the lower side of the leg support main body 1. The second motor E1 has two second output shafts e, and the two second output shafts e correspond to the two groups of rotating shafts 3 one by one. The corresponding second output shaft e is power-connected to the rotating shaft 3 through a transmission component E2. The two groups of rotating shafts 3 share one motor, and the second motor E1 can drive the two groups of rotating shafts 3 to rotate synchronously through the transmission component E2.

[0058] Furthermore, again as Figure 10 , 11As shown in FIGS. 11 and 12, the transmission assembly E2 includes a first transmission gear E21 sleeved on the second output shaft e, and a second transmission gear E22 sleeved in the middle of the rotating shaft 3. The second transmission gear E22 meshes with the first transmission gear E21. The second motor E1 drives the first transmission gear E21 on the second output shaft e to rotate, which can drive the corresponding second transmission gear E22 to rotate. The transmission modes of the two groups of rotating shafts 3 are the same, and will not be elaborated here.

[0059] In this embodiment, the second motor E1 is located between the two rotating shafts 3. The second output shaft e of the second motor E1 is located below the rotating shaft 3 and is perpendicular to the rotating shaft 3. Both the first transmission gear E21 and the second transmission gear E22 are helical gears, and the first transmission gear E21 and the corresponding second transmission gear E22 are staggeredly arranged in space, forming a helical gear transmission with two intersecting shafts. With such a design, compared with other gear transmission modes, such as: coaxial gear transmission and belt gear transmission, it can reduce the occupied space of transmission components and make the overall structure of the device more compact.

[0060] Combined with Figure 10 and Figure 11 As shown, taking one of the bottom massage mechanisms D on the left side as an example, a second eccentric bracket 7 protruding radially outward is fixedly provided at the left end of the rotating shaft 3. The bottom massage mechanism D is rotatably installed at the distal end of the second eccentric bracket 7. With such a design, when the rotating shaft 3 rotates, it can drive the second eccentric bracket 7 to rotate, thereby driving the bottom massage mechanism D to revolve and rotate around the rotating shaft 3, further deepening the stimulation of the massage protrusions D1 to the muscles and improving the massage effect.

[0061] Referring again to Figure 2 and 11 , the rotating shaft 3 is horizontally arranged in the middle of the leg rest main body 1. A support shaft 8 coaxially opposite to the rotating shaft 3 is rotatably installed on the left side of the leg rest main body 1. A first eccentric bracket 9 protruding radially outward is fixedly provided on the support shaft 8. One end of the bottom massage mechanism D away from the second eccentric bracket 7 is rotatably connected to the first eccentric bracket 9. With such a design, the stability of the support and rotation of the bottom massage mechanism D can be ensured. On the same rotating shaft 3, the connection structure of the bottom massage mechanism D at the right end of the rotating shaft 3 is the same as that at the left end, and the two groups of rotating shafts 3 have the same structure, which will not be elaborated here.

[0062] As Figure 10 shown, a first mounting seat 10 extending downward is fixedly assembled on the lower side of the leg rest main body 1. Two first connection through holes 10a are provided on the first mounting seat 10. The two first connection through holes 10a are distributed along the length direction of the leg rest main body 1. Each of the two groups of rotating shafts 3 is rotatably supported on the two first connection through holes 10a through bearings respectively. To increase the stability of the support of the rotating shaft 3, in this embodiment, there are two groups of first mounting seats 10.

[0063] Referring again to Figure 2And 10 , on both left and right ends of the lower side of the leg support main body 1, second mounting seats 13 extending downward are fixedly provided. Two second connection through holes 13a are provided on the second mounting seats 13, and the two second connection through holes 13a are distributed along the length direction of the leg support main body 1 in the opposite direction. The left ends of the two support shafts 8 on the left side are rotatably supported in the two second connection through holes 13a on the left second mounting seat 13 through bearings, and the two support shafts 8 on the right side are arranged in the same structure as above.

[0064] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without departing from the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
