[0043] The present invention will be further described below in conjunction with the embodiments and the drawings.

[0044] As Figure 15 and 16 shown, a vehicle seat includes a seat frame assembly F. A leg rest F1 is rotatably installed on the front side of the seat frame assembly F. The leg rest F1 is integrated with a calf side massage device, which can massage and relax the calf muscles of the user. The structure of the calf side massage device will be described in detail below. In the following embodiments, the orientation description of the leg rest plate 1 is based on the vehicle seat, that is, the width direction of the leg rest main body 1 corresponds to the width direction of the vehicle seat.

[0045] Embodiment 1

[0046] As Figures 1 to 3As shown in the figure, a calf side massage device includes a leg support plate 1, on which a splint sleeve group A is movably installed. The splint sleeve group A can be unfolded and surrounded to form two accommodating grooves a distributed left and right. The splint sleeve group A is integrated with a massage component 2 in the side area corresponding to the accommodating groove a. A driving component B is also provided on the leg support plate 1, and the driving component B can drive the splint sleeve group A to unfold to form two accommodating grooves a.

[0047] Based on the above structural design, during use, the driving component B drives the splint sleeve group A to unfold to the upper side of the leg support plate 1 and surround to form two accommodating grooves a. The user's calves can be placed in the two accommodating grooves a. The splint sleeve group A can clamp the two sides of the calves. When the massage component 2 works, it can massage the two sides of the calves, thereby effectively relieving the leg fatigue of the occupant. When not in use, the splint sleeve group A can be folded on the leg support plate 1 to keep the surface of the leg support plate 1 flat, without occupying the foot space of the occupant, having the technical advantages of compact, reasonable structure and good overall aesthetics.

[0048] Furthermore, as shown in Figure 4 , 11 and 14, after the splint sleeve group A is unfolded, the accommodating groove a is a rectangular groove, a regular trapezoidal groove, an inverted trapezoidal groove or a V-shaped groove. In this embodiment, the accommodating groove a is an inverted trapezoidal groove.

[0049] Please refer to Figure 1 and 2 , the splint sleeve group A includes a first splint A1, a second splint A2, a third splint A3 and a fourth splint A4 assembled in sequence in the width direction of the leg support plate 1. All four splints can be flipped relative to the leg support plate 1 and moved in the width direction. The driving component B can drive the four splints to flip and move relative to the leg support plate 1. It can be seen from Figure 7 that the massage component 2 is arranged on the upper surfaces of the four splints. When the four splints surround to form two accommodating grooves a through movement and flipping, the massage components 2 on the first splint A1 and the second splint A2 can correspond to the two sides of the left accommodating groove a, and the massage components 2 on the third splint A3 and the fourth splint A4 can correspond to the two sides of the right accommodating groove a. Among them, the massage component 2 is a massage air bag or a mechanical massage component. In this embodiment, the massage component 2 is preferably a massage air bag. After the user's calves are placed in the two accommodating grooves a, the massage air bag inflates and deflates cyclically, and can respectively massage the two sides of the two calves by pinching and kneading.

[0050] Refer to Figure 4 and 5, a first clamping plate A1 and the leg support plate 1 are provided with a first connecting rod 3. One end of the first connecting rod 3 is hinged to the lower side of the first clamping plate A1, and the other end is hinged to the left end of the leg support plate 1. The lower side of the first clamping plate A1 is the side facing the leg support plate 1 when the first clamping plate A1 is folded. A second connecting rod 4 is provided between the fourth clamping plate A4 and the leg support plate 1. The connection principle of the second connecting rod 4 is the same as that of the first connecting rod 3, that is, one end of the second connecting rod 4 is hinged to the lower side of the fourth clamping plate A4, and the other end is hinged to the right end of the leg support plate 1. The connection between the second clamping plate A2 and the third clamping plate A3 is hinged to each other. The driving assembly B includes a lead screw B1 rotatably arranged on the leg support plate 1, four sliders B3 slidably arranged on the leg support plate 1, and a motor B2 for driving the lead screw B1 to rotate. Among them, the lead screw B1 extends along the width direction of the leg support plate 1, and the four sliders B3 are all 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 difficulty of assembly and adjustment, 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.

[0051] Taking Figure 5 as a 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 the 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 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 lead screw B1b. Combining Figure 4 shown, when the lead screw B1 rotates, the two sliders B3 on the left section lead screw B1a move left and right respectively, and the two sliders B3 on the right section lead screw B1b move left and right respectively. The slider B3 moving left on the left section lead screw B1a drives the right end of the first clamping plate A1 to slide left. At this time, under the action of the first connecting rod 3, 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 lead screw B1a can drive the left end of the second clamping plate A2 to slide right, and the slider B3 moving left on the right section lead screw B1b can drive the right end of the third clamping plate A3 to slide left. At this time, under the mutual hinge action of the second clamping plate A2 and the third clamping plate A3, the second clamping plate A2 and the third clamping plate A3 can be driven to rotate upward simultaneously. The slider B3 moving right on the right section 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 4, the fourth clamping plate A4 can rotate upward with the slider as the rotation fulcrum while moving. Thus, the first clamping plate A1 and the second clamping plate A2 can enclose a receiving groove a, and the third clamping plate A3 and the fourth clamping plate A4 enclose another receiving groove a. Both groups of receiving grooves a are trapezoidal structures with the upper base smaller than the lower base.

[0052] Furthermore, asFigure 4 and 6 As shown in 6 , the lead screw B1 is axially 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 in sequence, and each of the four sliders B3 corresponds to one thread section. With such a design, adjacent two sliders B3 can move in opposite directions.

[0053] Please refer to Figure 6 , connection blocks B31 extending upward are fixedly provided inside each of the four sliders B3, and 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 connection blocks B31 through rotating members b. Such consideration is for the convenience of assembly.

[0054] Refer to again Figure 3 and 6 , in this embodiment, there are two sets of lead screws B1. Both sets of lead screws B1 extend along the width direction of the leg rest plate 1 and are distributed at both ends in the length direction of the bottom of the leg rest plate 1. The structures of both sets of lead screws B1 are the same and will not be elaborated here. The motor B2 is arranged at the right end of the leg rest plate 1. The motor B2 has two output shafts, and first gears B21 are assembled on both output shafts. Second gears B11 are provided at the right ends of both sets of lead screws B1. As can be seen from combining Figure 5 , 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 motor B2 at the end and using helical gear transmission can reduce the occupied space of the drive assembly 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 plate 1 can leave space in the middle of the leg rest plate 1, and a massage mechanism such as a massage airbag can be arranged in the middle of the leg rest plate 1 according to requirements, increasing the massage of the back of the calf.

[0055] For another example Figure 6 As shown in Figure 6 , mounting seats 11 are fixedly assembled at the end positions of the bottom of the leg rest plate 1 corresponding to the two sets of lead screws B1, and both ends of the lead screw B1 are respectively rotatably supported in the corresponding mounting seats 11. The number of the first connecting rods 3 is two sets, and one ends of the two sets of first connecting rods 3 are respectively hinged on the two left mounting seats 11. Similarly, one ends of the two sets of second connecting rods 4 are respectively hinged on the two right mounting seats 11.

[0056] Embodiment 2

[0057] In this embodiment, after the clamping plate sleeve group A is unfolded, the receiving groove a is a rectangular groove.

[0058] Please refer to Figure 8 and 9, the splint set A includes three groups of partitions A5 arranged in sequence along the width direction of the leg support plate 1, and the three groups of partitions A5 are installed on the leg support plate 1 in a lifting manner. After the driving component B drives the three groups of partitions A5 to rise above the leg support plate 1, the two accommodation grooves a formed by the three groups of partitions A5 are rectangular grooves. Among the three groups of partitions A5, the massage member 2 is arranged on the inner sides of the partitions A5 on both sides and on both sides of the partition A5 in the middle.

[0059] In this embodiment, among the three groups of partitions A5, the partition A5 in the middle can be composed of two plate bodies.

[0060] Such as Figure 11 shown, vertical installation grooves 12 extending downward are provided at the positions of the leg support plate 1 corresponding to the partitions A5, and each partition A5 is slidably assembled up and down in the corresponding installation groove 12.

[0061] Furthermore, as Figure 10 and 11 shown, taking the partition A5 in the middle as an example, the driving component B includes a second motor B5 arranged at the bottom of its corresponding installation groove 12 and a second lead screw B6 driven by the second motor B5 to rotate. The second lead screw B6 extends along the height direction of the installation groove 12, and a slider B7 is fixedly provided at the bottom of the partition A5. The slider B7 is slidably sleeved on the second lead screw B6. When the second motor B5 drives the second lead screw B6 to rotate, the partition A5 can be driven to move up and down.

[0062] Embodiment Three

[0063] In this embodiment, after the splint set A is unfolded, the accommodation groove a is a rectangular groove.

[0064] Such as Figure 12 shown, this embodiment is different from Embodiment Two. The splint set A includes three groups of baffles A6 arranged in sequence along the width direction of the leg support plate 1. The three groups of baffles A6 can rotate upward or downward relative to the leg support plate 1. That is, one end of the three groups of baffles A6 is connected by a rotating shaft. The driving component B drives the rotating shaft to rotate, which can drive the three groups of baffles A6 to rotate upward above the leg support plate 1 to form two rectangular accommodation grooves a, or drive the three groups of baffles A6 to rotate downward to the lower side of the leg support plate 1 (refer to Figure 13 ), avoiding interfering with the user's leg activities and maintaining the aesthetics of the device exterior.

[0065] Embodiment Four

[0066] In this embodiment, after the splint set A is unfolded, the accommodation groove a is a V-shaped groove.

[0067] Please refer to Figure 14, the splint set A includes four groups of fifth splints A7 arranged in sequence along the width direction of the leg support plate 1. One ends of the four groups of fifth splints A7 are all rotatably connected to the leg support plate 1, and the driving assembly B can drive two adjacent groups of fifth splints A7 to rotate upwards, so that the four groups of fifth splints A7 enclose two accommodating grooves a in a V-shaped structure.

[0068] Embodiment Five

[0069] Please refer to Figure 17 and 18 , in this embodiment, the splint set A includes four baffle plates A8 all rotatably connected to the upper side of the leg support plate 1. The baffle plates A8 can be flipped from the horizontal state to the inclined state (refer to Figure 17 → Figure 18 ). After each baffle plate A8 is flipped and unfolded to the inclined state, the two baffle plates A8 at the left end and the two baffle plates A8 at the right end respectively enclose an accommodating groove a. The massage component 2 is arranged on the surface of the baffle plate A8. When the calf is placed in the two accommodating grooves a and the massage component 2 works, the side part of the calf can be massaged.

[0070] Furthermore, referring to Figure 18 again, each baffle plate A8 includes an inner plate body A81 hinged to the leg support plate 1 and an outer plate body A82 that can slide and stretch relative to the inner plate body A81. During the process of the baffle plate A8 being flipped and unfolded towards the inclined state, the outer plate body A82 can be driven to extend outwards, so as to expand the side blocking and supporting area of the baffle plate A8, making the wrapping of the baffle plate A8 around the calf better and improving the massage effect. On the contrary, during the process of the inner plate body A81 rotating and folding towards the leg support plate 1, the outer plate body A82 can be retracted inwards to ensure the compactness of the structure when the mechanism is in the unused state.

[0071] It can be seen from Figure 18 that in this embodiment, the outer plate body A82 and the inner plate body A81 are telescopically linked through a linkage assembly A9. When the inner plate body A81 rotates from the horizontal state to the inclined state, the linkage assembly A9 can drive the outer plate body A82 to extend outwards in a linked manner; when the inner plate body A81 rotates from the inclined state to the horizontal state, the linkage assembly A9 can drive the outer plate body A82 to retract inwards in a linked manner.

[0072] For another example, as shown in Figure 17 and 18 , a bottom massage area A83 is provided between the two baffle plates A8 at the left end and between the two baffle plates A8 at the right end. The bottom massage area A83 is integrated with massage air bags. With such a design, the massage function on the back side of the calf is increased, so that the user's calf can be massaged in all directions and at multiple angles.

[0073] Finally, it should be noted that the above description is only the preferred embodiment of the present utility model.
