Description

Technical Field

[0001] The present application relates to the technical field of massage devices, and in particular to a massage assembly, a leg support device, a seat and a vehicle. Background Art

[0002] Massage devices are typically used to massage the legs, waist, and other areas of the body to enhance comfort and relaxation. As drivers and passengers increasingly demand greater ride comfort, some vehicles are now equipped with leg rests equipped with massage components to massage the legs, enhancing passenger comfort.

[0003] In the prior art, when a massage component provided on a vehicle seat massages the legs, the fit between the legs and the massage component is not stable enough, resulting in a poor massage effect on the legs, affecting the experience of the driver and passengers. Summary of the Invention

"Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.

[0076] As people's quality of life improves, they demand ever-higher comfort in seats 200. For example, a leg rest 210 can be provided on seat 200 to support the occupant's legs, accommodating different sitting postures and enhancing riding comfort. A massage component 20 can also be provided on leg rest 210 to massage the legs, relieving fatigue and enhancing comfort.

[0077] It should be understood that the seat 200 can be a seat 200 used at home or in the office, or a seat 200 used in a public place, such as a movie theater, a cafe, etc. The seat 200 can also be a seat used in a vehicle, such as an airplane seat, a train seat, a car seat, etc.

[0078] For ease of understanding, the embodiment of the present application is described by taking the seat 200 applied to the vehicle 1000 as an example.

[0079] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of the present application. Vehicle 1000 can be a pure gasoline vehicle, a pure electric vehicle, a hybrid vehicle, etc. Vehicle 1000 can also be a car, a bus, a van, a truck, a trailer, etc.

[0080] Vehicle 1000 may include a vehicle body 100 and seats 200 disposed within the vehicle body 100. The seats 200 are connected to the vehicle body 100 via a frame and are used to carry passengers or cargo. The seats 200 typically include a driver's seat 200, a passenger seat 200, and rear seats 200. The rear seats 200 may be arranged in multiple rows along the length of the vehicle 1000, depending on the interior space of the vehicle 1000. The seats 200 may be equipped with heating devices that regulate the surface temperature of the seats 200 to enhance passenger comfort.

[0081] See Figure 2 , Figure 2 for Figure 1 Schematic diagram of the structure of the seat 200 of the vehicle 1000. The seat 200 can also be provided with a leg support device 210, which supports the legs of the driver and passenger to accommodate different sitting postures of the driver and passenger and improve riding comfort.

[0082] A massage component 20 may also be provided on the leg support device 210. The leg support device 210 supports the legs of the driver and passenger while massaging the legs through the massage component 20, thereby improving riding comfort.

[0083] In some embodiments, see Figure 3 and Figure 4 , Figure 3 for Figure 2 Schematic diagram of the leg support device 210 of the middle seat 200 from a first perspective, Figure 4 for Figure 2 Schematic diagram of the leg support device 210 of the middle seat 200 at a second viewing angle. Figure 3 and Figure 42 shows a massage assembly 20 for a leg support device 210 of a seat 200. The leg support device 210 includes a fixing plate 10. The massage assembly 20 comprises a massage structure 1 and a retaining structure 2. The massage structure 1 has a massage surface 111 suitable for massaging the legs and includes a first end and a second end opposite to each other. The first end is suitable for connecting to the fixing plate 10, and the second end is suitable for connecting to the retaining structure 2.

[0084] In some examples, the massage structure 1 may include magnets to massage the legs.

[0085] In other examples, the massage structure 1 may include a mechanical massage structure, which is provided with a reciprocating member such as a crankshaft, and the reciprocating member intermittently squeezes or beats the legs to achieve leg massage.

[0086] In some other examples, the massage structure 1 may include a massage air bag, which is inflated and deflated to cause the massage air bag to intermittently squeeze the legs, thereby achieving leg massage.

[0087] In some examples, a first rotating shaft can be provided on the fixing plate 10, and the massage structure 1 can be rotatably connected to the first rotating shaft, so that the fixing plate 10 can be rotated relative to the massage structure 1 to adjust the limiting angle and position of the fixing plate 10 on the leg.

[0088] In other examples, a mounting frame may be provided on the fixing plate 10, and connected to the first end of the massage structure 1 via the mounting frame. The mounting frame may realize actions such as rotation and translation.

[0089] In some examples, the limiting structure 2 is rotatably connected to the second end of the massage structure 1. For example, a second rotating shaft is provided at the second end of the massage structure 1, and the limiting structure 2 is rotatably connected to the second rotating shaft.

[0090] In order to cover the legs through the limiting structure 2, at least a portion of the limiting structure 2 is located on the side facing the massage surface 111 and is suitable for defining a covering space for covering the legs together with the fixing plate 10.

[0091] In some examples, the limiting structures 2 are all located on the side facing the massage surface 111 .

[0092] In other examples, part of the limiting structure 2 is located on the side facing the massage surface 111. For example, a receiving cavity is provided at the second end of the massage structure 1, and part of the limiting structure 2 is located in the receiving cavity, so that part of the limiting structure 2 is located on the side facing the massage surface 111.

[0093] In some examples, the limiting structure 2 may include a limiting plate 21 , and an enclosing space is defined by the limiting plate 21 and the fixing plate 10 .

[0094] In other examples, the limiting structure 2 may include a plurality of limiting rods, and the plurality of limiting rods may be located on the side of the leg facing away from the fixing plate 10 to limit the side of the leg facing away from the fixing plate 10 .

[0095] In the above embodiment, the first end of the massage structure 1 is connected to the fixed plate 10, and the second end is connected to the limiting structure 2, with the limiting structure 2 being at least partially located on the side facing the massage surface 111. In this way, the fixed plate 10, the massage surface 111 of the massage structure 1, and the limiting structure 2 enclose and define a covering space that encloses the legs. When massaging the legs, the legs can be placed within the covering space, and the covering space is used to limit the legs. In this way, the massage assembly 20 can better wrap the legs, preventing the legs from being lifted up due to squeezing during the massage process, allowing the legs to fit more closely to the massage surface 111, ensuring the stability of the fit between the legs and the massage surface 111, and improving the massage effect on the legs.

[0096] In some embodiments, see Figure 3 、 Figure 4 The limiting structure 2 has a limiting surface 211 for covering the leg. The limiting structure 2 is rotatably connected to the massage structure 1 to adjust the angle between the limiting surface 211 and the massage surface 111. Because the limiting structure 2 is rotatably connected to the massage structure 1, the angle between the limiting surface 211 of the limiting structure 2 and the massage surface 111 can be adjusted so that the limiting surface 211 of the limiting structure 2 can fit the leg to limit the leg regardless of the leg circumference. This allows the massage assembly 20 to adapt to drivers and passengers with different leg circumferences. In addition, by adjusting the angle between the limiting surface 211 and the massage surface 111, the degree of coverage of the leg by the massage assembly 20 can be adjusted, thereby improving the comfort of the massage.

[0097] In some examples, the limiting surface 211 of the limiting structure 2 is a plane.

[0098] In other examples, the limiting surface 211 of the limiting structure 2 is an arc-shaped surface.

[0099] In some examples, the limiting structure 2 and the massage structure 1 may be rotatably connected via a third rotating shaft.

[0100] In some examples, the massage structure 1 has a certain thickness and is provided with a receiving cavity. The limiting structure 2 is rotatably connected to the receiving cavity. Part of the limiting structure 2 can extend outside the receiving cavity to limit the position of the leg. The opening width of the receiving cavity ensures that the limiting structure 2 can rotate within a certain angle range relative to the massage structure 1.

[0101] In some embodiments, the massage assembly 20 further includes a first drive structure for driving the limiting structure 2 to rotate relative to the massage structure 1. By driving the limiting structure 2 to rotate with the first drive structure, the angle between the limiting surface 211 of the limiting structure 2 and the massage surface 111 of the massage structure 1 can be easily adjusted, so that the covering space can be adapted to the leg circumference of different users.

[0102] In some examples, the first driving structure can be a telescopic rod device, such as a cylinder, an electric push rod, or a hydraulic rod, etc. One end of the telescopic rod device is fixed, and the other end is rotatably connected to the limiting structure 2. The limiting structure 2 rotates relative to the massage structure 1 as the telescopic rod device is extended or retracted.

[0103] In other examples, the first driving structure may include a motor and a fourth rotating shaft, wherein the fourth rotating shaft is rotationally connected to the massage structure 1 and is fixedly connected to the limiting structure 2. The motor drives the fourth rotating shaft to rotate, thereby driving the limiting structure 2 to rotate relative to the massage structure 1.

[0104] In some embodiments, see Figure 4 The first drive structure includes a first drive member 22 and a second drive member 23. The first drive member 22 is used to drive the limiting structure 2 to rotate toward the massage structure 1, and the second drive member 23 is used to drive the limiting structure 2 to rotate away from the massage structure 1. The first drive member 22 and the second drive member 23 can drive the limiting structure 2 to rotate in opposite directions relative to the massage structure 1. When the first drive member 22 drives the limiting structure 2 to rotate toward the massage structure 1, the angle between the limiting surface 211 of the limiting structure 2 and the massage surface 111 increases, and the covering space becomes larger. When the second drive member 23 drives the limiting structure 2 to rotate away from the massage structure 1, the angle between the limiting surface 211 of the limiting structure 2 and the massage surface 111 decreases. By providing the first drive member 22 and the second drive member 23, the size of the covering space can be adjusted, thereby improving the comfort of the limiting structure 2 in covering the legs.

[0105] In some examples, the first drive member 22 and the second drive member 23 are simultaneously connected between the side of the limiting structure 2 facing away from the limiting surface 211 and the massage structure 1. For example, the first drive member 22 can be a first telescopic rod, and the second drive member 23 can be a second telescopic rod. The two ends of the first telescopic rod are respectively hinged to the side of the limiting structure 2 facing away from the limiting surface 211 and the massage structure 1. The contraction of the first telescopic rod drives the limiting structure 2 to rotate toward the massage structure 1. In this case, the first telescopic rod actively moves, and the second telescopic rod passively moves. The two ends of the second telescopic rod are respectively hinged to the side of the limiting structure 2 facing away from the limiting surface 211 and the massage structure 1. The extension of the second telescopic rod drives the limiting structure 2 to rotate away from the massage structure 1. In this case, the second telescopic rod actively moves, and the first telescopic rod passively moves.

[0106] In other examples, the first driving member 22 and the second driving member 23 are respectively disposed on both sides of the limiting structure 2. For example, the first driving member 22 acts on one side of the limiting surface 211 of the limiting structure 2, and the second driving member 23 acts on the side of the limiting structure 2 facing away from the limiting surface 211. When the first driving member applies force to one side of the limiting surface 211 of the limiting structure 2, the limiting structure 2 moves toward the massage structure 1; when the second driving member 23 applies force to the side of the limiting structure 2 facing away from the limiting surface 211, the limiting structure 2 moves away from the massage structure 1.

[0107] In some embodiments, the first driving member 22 comprises an elastic member connected between the massage structure 1 and the retaining structure 2, and exerts a force on the retaining structure 2 to rotate toward the massage structure 1. By connecting the elastic member between the massage structure 1 and the retaining structure 2, the elastic member exerts a force on the retaining structure 2 to rotate toward the massage structure 1, thereby driving the retaining structure 2 to rotate toward the massage structure 1. As the retaining structure 2 rotates toward the massage structure 1, the enclosed space defined by the retaining structure 2 and the fixing plate 10 gradually increases. This allows the size of the enclosed space to be adjusted to accommodate users with different leg circumferences, or the enclosed space to be opened up to provide more room for leg movement.

[0108] In some examples, the first driving member 22 can be a tension spring, the two ends of which are respectively connected to the side of the limiting structure 2 facing away from the limiting surface 211 and the massage structure 1, and the tension of the tension spring drives the limiting structure 2 to rotate toward the massage structure 1.

[0109] In other examples, the first driving member 22 can be an elastic rubber member, which is stretched and connected between the side of the limiting structure 2 facing away from the limiting surface 211 and the massage structure 1, and the limiting structure 2 is driven to rotate toward the massage structure 1 by the tension of the rubber member.

[0110] In some embodiments, the second driving member 23 comprises a pneumatic element, disposed between the retaining structure 2 and the massage structure 1, and configured to drive the retaining structure 2 to rotate away from the massage structure 1. Because the second driving member 23 is configured to drive the retaining structure 2 to rotate away from the massage structure 1, when the second driving member 23 applies a driving force to the retaining structure 2, the space defined by the retaining structure 2 and the fixing plate 10 tends to shrink, gradually bringing the retaining structure 2 closer to the leg. The compressibility of the gas in the pneumatic element creates a buffer space when the retaining structure 2 is in close contact with the leg, preventing the retaining structure 2 from excessively squeezing the leg and causing pain.

[0111] In some examples, the second driving member 23 may be a cylinder, one end of which is hinged to the limiting structure 2 and the other end of which is hinged to the massage structure 1. The limiting structure 2 is driven to rotate away from the massage structure 1 by the extension of the cylinder.

[0112] In some specific examples, the second driving member 23 comprises a driving air bag, which is positioned between the retaining structure 2 and the massage structure 1. When inflated, the driving air bag propels the retaining structure 2 to rotate away from the massage structure 1. By driving the retaining structure 2 to rotate away from the massage structure 1, the driving air bag absorbs impact forces, preventing excessive impact forces and discomfort when the retaining structure 2 contacts the leg. Furthermore, when uninflated, the driving air bag occupies little space, saving installation space.

[0113] When the first driving member 22 is an elastic member and the second driving member 23 is a driving air bag, inflating the driving air bag can push the limiting structure 2 to rotate away from the massage structure 1. Simultaneously, the limiting structure 2 applies a force to the elastic member, causing it to deform. Therefore, when the limiting structure 2 needs to rotate toward the massage structure 1, the driving air bag can be deflated. The elastic force of the elastic member then causes the limiting structure 2 to rotate toward the massage structure 1. This coordination of the elastic member and the driving air bag facilitates adjustment of the angle between the driving surface of the driving structure and the massage surface 111 of the massage structure 1.

[0114] In some embodiments, the limiting structure 2 includes a limiting plate 21 and a first massage element connected to the limiting plate 21. The limiting plate 21 is connected to the massage structure 1, and the first massage element is suitable for covering the leg. The limiting structure 2 includes the limiting plate 21 and the first massage element on the limiting plate 21. The limiting plate 21 can be used to limit the leg, and the first massage element can be used to massage the leg at the limit position, thereby increasing the massage area and improving comfort.

[0115] In some examples, the first massage element may be a magnet, a massage air bag, a massage plate, a massage ball, or the like.

[0116] In some embodiments, the first massage element includes a first gas massage element. Since the first gas massage element is driven by gas for massage, it has a good ability to absorb shock, thereby preventing shock or excessive squeezing on the legs during massage and improving massage comfort.

[0117] In some specific examples, the first gas massage element may be a massage air bag, which is inflated and deflated to provide an intermittent beating massage to the legs.

[0118] In some other specific examples, the first gas massage element may also be an air wave pressure massager.

[0119] In some embodiments, the massage assembly 20 further includes a first pressure detector connected to the first massage element for detecting the pressure applied by the first massage element to the leg. By detecting the pressure applied by the first massage element to the leg, the massage comfort can be ensured, preventing excessive pressure from the first massage element on the leg, which could cause discomfort such as pain, and also preventing insufficient pressure, which could result in an ineffective massage. Furthermore, the pressure detected by the first pressure detector can be used to reversely control the angle between the limiting structure 2 and the massage structure 1, thereby providing a good massage experience within the space defined by the limiting structure 2.

[0120] In some examples, the first pressure detecting member is a pressure sensor that can be bonded to the side of the first massage member near the leg using glue or the like. In this way, when the first massage member is massaging the leg, the first pressure detecting member is always located between the first massage member and the leg, and can detect the massaging force of the first massage member on the leg in real time, thereby facilitating adjustment of the angle of the limiting structure 2 relative to the massage structure 1 to ensure that the massage force is neither too strong nor too weak.

[0121] In some embodiments, the massage structure 1 includes a support plate 11 and a second massage member 112 connected to the support plate 11. The support plate 11 is adapted to be connected to the fixed plate 10. The second massage member 112 has a massage surface 111 on a side facing away from the support plate 11. The second massage member 112 is disposed on the support plate 11, and specifically, the massage surface 111 is configured on a side facing away from the support plate 11. The massage surface 111 massages the legs, thereby improving riding comfort.

[0122] In some examples, the limiting structure 2 may be connected to the support plate 11 . For example, the limiting structure 2 is connected to the support plate 11 via a connecting member such as a fifth rotating shaft, so that the limiting structure 2 is rotatably connected to the support plate 11 .

[0123] In other examples, the limiting structure 2 can be connected to the second massage member 112 . For example, a connecting member such as a sixth rotating shaft is provided on the second massage member 112 so that the limiting structure 2 is rotatably connected to the second massage member 112 .

[0124] In some examples, the structure of the second massage element 112 may be the same as that of the first massage element, and will not be described in detail herein.

[0125] In some embodiments, the massage assembly 20 further includes a second pressure sensor connected to the second massage element 112 for detecting the pressure applied by the second massage element 112 to the leg. This second pressure sensor detects the pressure applied by the second massage element 112 to the leg, preventing the massage force provided by the second massage element 112 from being too weak, resulting in an ineffective massage, or from being too strong, resulting in discomfort. This second pressure sensor ensures a comfortable massage.

[0126] In some examples, the second pressure detecting member may be a pressure sensor installed between the second massage member 112 and the support plate 11 .

[0127] In some embodiments, see Figure 3 、 Figure 4 The leg support device 210 further includes a massage mechanism, which includes a first massage component 20a and a second massage component 20b. That is, the massage mechanism includes two massage components 20 in any of the above-described embodiments, and the two massage components 20 form a single massage mechanism. For ease of distinction, the two massage components 20 are respectively named the first massage component 20a and the second massage component 20b. The structures of the first massage component 20a and the second massage component 20b may be the same or different.

[0128] The massage surface 111 includes a first massage surface 111a and a second massage surface 111b. The first massage surface 111a is provided on the first massage component 20a, and the second massage surface 111b is provided on the second massage component 20b. The first massage surface 111a and the second massage surface 111b are suitable for massaging the legs. In the above embodiment, the massage mechanism includes the first massage component 20a and the second massage component 20b. The first massage component 20a and the second massage component 20b cover both sides of the legs. The first massage surface 111a of the first massage component 20a and the second massage surface 111b of the massage component 20b massage both sides of the legs, thereby improving the massage comfort.

[0129] In some examples, the first massage component 20a and the second massage component 20b are arranged along the width direction of the seat 200, and the first massage surface 111a of the first massage component 20a and the second massage surface 111b of the second massage component 20b are arranged opposite to each other, respectively located on both sides of the legs, and are used to massage both sides of the legs.

[0130] In some embodiments, the leg support device 210 further includes a fixed plate 10, and the massage structure 1 is connected to the fixed plate 10 and can be switched between an expanded state and a retracted state relative to the fixed plate 10. When the massage structure 1 is in the expanded state, the first massage surface 111a of the first massage component 20a and the second massage surface 111b of the second massage component 20b face each other, defining an enclosing space for placing the legs, and the first massage surface 111a and the second massage surface 111b massage both sides of the legs within the enclosing space, thereby improving the massage comfort. When the massage structure 1 is in the retracted state, the first massage surface 111a of the first massage component 20a and the second massage surface 111b of the second massage component 20b both face away from the fixed plate 10. At this time, the massage structure 1 is a flat massage structure 1, and the side of the leg facing the fixed plate 10 can be massaged by the flat massage structure 1. By switching the massage structure 1 between the expanded state and the retracted state, different massage postures can be achieved, thereby improving the flexibility of use.

[0131] In some examples, the first massage component 20a and the second massage component 20b of the massage structure 1 can be rotatably connected to the fixed plate 10. By rotating the first massage component 20a and the second massage component 20b relative to the fixed plate 10, the massage structure 1 can be deployed and retracted.

[0132] In some embodiments, reference Figure 4 、 Figure 6 The massage mechanism further includes a first transmission structure 12 and a second transmission structure 13, and the leg support device 210 further includes a first drive assembly 14. The first transmission structure 12 is connected between the first drive assembly 14 and the first massage component 20a, and the second transmission structure 13 is connected between the first drive assembly 14 and the second massage component 20b. The first drive assembly 14 is used to drive the first massage component 20a and the second massage component 20b to move, thereby switching the massage mechanism between an extended state and a retracted state.

[0133] In this way, by arranging the first transmission structure 12 between the first drive component 14 and the first massage component 20a, and the second transmission structure 13 between the first drive component 14 and the second massage component 20b, the first drive component 14 can drive the first transmission structure 12 and the second transmission structure 13 to work, so that the first transmission structure 12 drives the first massage component 20a to move, and the second transmission structure 13 drives the second massage component 20b to move. Through the cooperation of the first massage component 20a and the second massage component 20b, the massage structure 1 can be switched between an expanded state and a retracted state to massage the legs. In this way, the first massage component 20a and the second massage component 20b can be driven to move simultaneously by only the first drive component 14. Compared with one drive component driving one massage component 20, this drive method has a simple structure and can reduce the number of components, thereby reducing the space occupied by the leg support device 210 in the seat 200. In addition, the cost is low.

[0134] In some other embodiments, the massage structure 1 may also include two driving structures, such as motors, one driving structure drives the first massage component 20a to move, and the other driving structure drives the second massage component 20b to move, so that the massage structure 1 can be switched between the expanded state and the retracted state.

[0135] In some embodiments, the first drive assembly 14 drives the first massage assembly 20a to swing relative to the fixed plate 10 through the first transmission structure 12, and the first drive assembly 14 drives the second massage assembly 20b to swing relative to the fixed plate 10 through the second transmission structure 13. The swinging direction of the first massage assembly 20a is opposite to the swinging direction of the second massage assembly 20b.

[0136] Illustratively, during the switching of the massage structure 1 from the deployed state to the retracted state, an end of the first massage member proximate to the fixed plate 10 and an end of the second massage member 112 proximate to the fixed plate 10 move toward each other, while an end of the first massage member 112 distal to the fixed plate 10 and an end of the second massage member 112 distal to the fixed plate 10 move away from each other, thereby achieving opposite swing directions of the first massage member 112. During the switching of the massage structure 1 from the retracted state to the deployed state, the ends of the first massage member 112 distal to each other gradually move away from the fixed plate 10 and gradually move toward each other, while an end of the first massage member 112 distal to each other gradually moves away from each other, thereby achieving opposite swing directions of the first massage member 112.

[0137] In this way, the reverse swing of the first massage component 20a and the second massage component 20b can make the massage structure 1 in the retracted state, with the first massage surface 111a of the first massage component and the second massage surface 111b of the second massage component 20b both facing away from the fixed plate 10. At this time, when massaging the side of the leg facing the fixed plate 10, the placement position of the leg can be increased, that is, the legs can be placed at the positions of the first massage surface 111a and the second massage surface 111b, and both can massage the legs, so as to improve the massage effect of the legs and improve the driving experience of the person on the seat 200.

[0138] In some other embodiments, the first massage component 20a and the second massage component 20b may also have the same swing direction. In this case, when the massage structure 1 is in the retracted state, the side of the first massage component 20a facing the fixed plate 10 and the side facing away from the fixed plate 10 are both set as the first massage surface 111a, and / or the side of the second massage component 20b facing the fixed plate 10 and the side facing away from the fixed plate 10 are both set as the second massage surface 111b. In this way, the placement position of the legs can be increased and the massage effect of the legs can be improved.

[0139] In some embodiments, see Figure 4 and Figure 6 The first drive assembly 14 includes a first motor 141 and a first transmission shaft 142. The first motor 141 is connected to the fixed plate 10. The first transmission shaft 142 is rotationally connected to the fixed plate 10. The output shaft of the first motor 141 is in transmission connection with the first transmission shaft 142. The first transmission structure 12 and the second transmission structure 13 are both connected to the first transmission shaft 142. The axial direction of the first transmission shaft 142 can be consistent with the width direction of the seat 200 and parallel to the fixed plate 10. The width direction of the seat 200 is the width direction of the vehicle 1000.

[0140] In this manner, by connecting the output shaft of first motor 141 to first transmission shaft 142, first motor 141 can drive first transmission shaft 142 to rotate, thereby driving first transmission structure 12 and second transmission structure 13 to rotate, causing first and second massage elements 112 to swing relative to fixed plate 10, thereby switching massage structure 1 between an extended state and a retracted state. First transmission shaft 142 has a simple structure and occupies a small space, which can reduce the space occupied by the leg support structure and facilitate the placement of seat 200 within vehicle 1000.

[0141] In some other examples, the first driving assembly 14 may also include multiple motors, one motor drives the first transmission structure 12 , and another motor drives the second transmission structure 13 .

[0142] In some embodiments, the first transmission structure 12 includes a first gearing 121 and a second gearing 122. The first gearing 121 is fixed to the first transmission shaft 142. The second gearing 122 engages with the first gearing 121 and is rotatable about a first axis, which is perpendicular to the axis of the first transmission shaft 142. The second gearing 122 is in transmission connection with the first massage component 20a. For example, the second axis is parallel to the fixed plate 10 and coincides with the height of the seat 200, which is the height of the vehicle 1000. The second gearing 122 is in transmission connection with the first massage component.

[0143] In this way, by fixing the first engagement member 121 to the first transmission shaft 142, the second engagement member 122 engages with the first engagement member 121, so that the driving force output by the first motor 141 is transmitted to the first engagement member 121 through the first transmission shaft 142, thereby driving the second engagement member 122 to rotate about the first axis, thereby causing the first massage member to swing. The provision of the first transmission structure 12 can facilitate the spatial arrangement of the first transmission shaft 142 and the first massage member, making the arrangement of the first transmission shaft 142 and the first massage member more reasonable.

[0144] In some embodiments, see Figure 6 、 Figure 7 The first engaging member 121 includes a worm, and the second engaging member 122 includes a worm wheel.

[0145] In this way, the driving force output by the first motor 141 is transmitted to the worm via the first transmission shaft 142. The worm engages with the worm wheel, driving the worm wheel to rotate about the first axis, thereby transmitting the driving force to the first massage element. The worm gear features a 90° staggered transmission on both axes, which allows for efficient transmission of the driving force to the first massage element. Furthermore, compared to multi-stage gear transmissions, the worm wheel and worm are relatively compact, reducing the space occupied by the leg support device 210 within the seat 200.

[0146] In some other examples, the first engaging member 121 and the second engaging member 122 may also be bevel gears, both of which can transmit the driving force output by the motor to the first massage member.

[0147] In some other embodiments, the first transmission structure 12 may also be a belt transmission structure, a chain transmission structure, etc.

[0148] In some embodiments, see Figure 7 The first transmission structure 12 further includes a first connecting shaft 123 , the first connecting shaft 123 is rotatably connected to the fixed plate 10 , the second engaging member 122 is connected to the first connecting shaft 123 , and the axis of the first connecting shaft 123 is the first axis.

[0149] In this way, the first connecting shaft 123 facilitates the connection between the second engaging member 122 and the first massage member, thereby facilitating the transmission of the driving force output by the first motor 141 to the first massage member through the first connecting shaft 123 to cause the first massage member to swing.

[0150] In some embodiments, see Figure 7 The first transmission structure 12 further includes a first connecting rod 124 assembly, which includes a first connecting rod 124 and a second connecting rod 125. One end of the first connecting rod 124 is rotatably connected to the first massage assembly 20a, and the other end of the first connecting rod 124 is connected to the first connecting shaft 123. One end of the second connecting rod 125 is rotatably connected to the first massage assembly 20a, and the other end of the second connecting rod 125 is rotatably connected to the fixed plate 10. When the massage mechanism is in the deployed state, the first connecting rod 124 and the second connecting rod 125 are spaced apart along the axial direction of the first transmission shaft 142.

[0151] In this way, the first connecting rod 124, the second connecting rod 125, the first massage element, and the fixed plate 10 form a four-bar structure. When the first connecting shaft 123 rotates, the first connecting rod 124 and the second connecting rod 125 can drive the first massage element to move to different positions, so that the first massage element moves in a swinging manner. That is, the first connecting rod 124 and the second connecting rod 125 can define the swinging trajectory of the first massage element. When the massage structure 1 switches between the deployed state and the retracted state, the first massage element moves in a smaller space, thereby further reducing the space occupied by the leg support device 210.

[0152] Specifically, the driving force output by the first motor 141 is transmitted to the worm through the first transmission shaft 142, and the worm is meshed with the worm gear for transmission, thereby driving the worm gear to rotate around the first axis. The worm gear is connected to the first connecting shaft 123, and the worm gear drives the first connecting shaft 123 to rotate with the worm gear. The rotation of the first connecting shaft 123 will drive the end of the first connecting rod 124 connected to the first connecting shaft 123 to rotate, thereby causing the end of the first connecting rod 124 connected to the first massage part to swing. The swinging of the end of the first connecting rod 124 connected to the first massage part will drive the first massage part to swing accordingly. The swinging of the first massage part will drive the second connecting rod 125 to swing. At the same time, the end of the second connecting rod 125 connected to the first massage part rotates relative to the first massage part, and the end of the second connecting rod 125 connected to the fixed plate 10 rotates relative to the fixed plate 10. Thus, under the action of the first connecting rod 124 and the second connecting rod 125, when the massage structure 1 switches from the deployed state to the retracted state, the end of the first massage element closer to the fixed plate 10 moves closer to the second massage element 112, and simultaneously, the end of the first massage element farther from the fixed plate 10 moves away from the second massage element 112 and moves closer to the fixed plate 10. When the massage structure 1 switches from the retracted state to the deployed state, the end of the first massage element farther from the second massage element 112 gradually moves away from the fixed plate 10 and gradually moves closer to the second massage element 112, and simultaneously, the end of the first massage element closer to the second massage element 112 gradually moves away from the second massage element 112.

[0153] If the first massage surface 111a of the first massage element is facing away from the fixed plate 10 and is parallel to the fixed plate 10, the first massage element is in a retracted state; if the massage angle of the first massage element changes within a certain range (the massage angle is greater than 0° and less than or equal to 90°), the first massage element is in an extended state.

[0154] Among them, the worm gear and the worm are driven to work by the first transmission shaft 142, thereby driving the first massage part to move through the first connecting rod 124 and the second connecting rod 125. The first massage surface 111a of the first massage part can be rotated to any angle between 0° and 90° relative to the fixed plate 10 according to the leg shape and massage needs of the driver and passenger, so as to improve the covering effect of the first massage part on the leg, and can massage different positions of the leg, further improving the flexibility and massage effect of the massage structure 1.

[0155] Furthermore, the above arrangement makes the massage structure 1 more compact, thereby reducing the dimension of the leg support device 210 in the thickness direction of the fixing plate 10, thereby reducing the space occupied by the leg support device 210 in the seat 200, facilitating overall vehicle layout, and being particularly suitable for use in scenarios where the space in front of the rear seat 200 is limited (such as a compact vehicle 1000), thereby improving the overall practicality of the seat 200. The thickness direction of the fixing plate 10 coincides with the length direction of the seat 200 (i.e., the length direction of the vehicle 1000).

[0156] In some examples, a group of first connecting rod 124 components can be respectively provided at the upper and lower ends of the first massage component 20a along the height direction of the seat 200 to improve the rotation stability of the first massage component 20a.

[0157] In some embodiments, see Figure 6 、 Figure 8 The first transmission shaft 142 is provided with an external thread, and the second transmission structure 13 includes a moving member 131 and a transmission connecting rod 132. The moving member 131 is provided with an internal thread. The moving member 131 extends along the circumference of the first transmission shaft 142, and the internal thread is screwed to the external thread. One end of the transmission connecting rod 132 is rotationally connected to the moving member 131, and the other end of the transmission connecting rod 132 is rotationally connected to the first end of the second massage component 20b. Because the first transmission shaft 142 and the moving member 131 are connected by the external thread and the internal thread, when the first transmission shaft 142 rotates, the moving member 131 is displaced along the axis of the first transmission shaft 142 under the drive of the threads. Because one end of the transmission connecting rod 132 is connected to the moving member 131 and the other end is connected to the second massage component 20b, when the moving member 131 is displaced along the axis of the first transmission shaft 142, the second massage component 20b is pulled to move through the transmission connecting rod 132. When the second massage component 20b is rotatably connected to the fixed plate 10, the transmission connecting rod 132 can pull the second massage component 20b to rotate relative to the fixed plate 10, thereby realizing the switching of the second massage component 20b between the deployed state and the retracted state, and the massage mode is more flexible.

[0158] Since the first transmission structure 12 is driven by the rotation of the first transmission shaft 142, and the second transmission structure 13 is also driven by the rotation of the first transmission shaft 142, the first drive assembly 14 can simultaneously drive the first massage assembly 20a and the second massage assembly 20b to switch between the open state and the closed state. This structure is simple and space-saving.

[0159] In some examples, the moving member 131 is hingedly connected to one end of the transmission link 132, and the other end of the transmission link 132 is hingedly connected to the second massage component 20b.

[0160] In some embodiments, the leg support device 210 further includes a second connecting rod 125 assembly, one end of which is movably connected to the fixed plate 10, and the other end of which is movably connected to the second massage assembly 20b. The structure of the second connecting rod 125 assembly can be the same as that of the first connecting rod 124 assembly. The second connecting rod 125 assembly connects the fixed plate 10 and the second massage assembly 20b, thereby improving the rotational stability of the second massage assembly 20b relative to the fixed plate 10.

[0161] It should be noted that the structure of the second connecting rod 125 assembly can be the same as the structure of any of the above-mentioned first connecting rod 124 assembly embodiments, and will not be repeated here.

[0162] In some embodiments, there may be multiple massage mechanisms, which are spaced apart along the axial direction of the first transmission shaft 142. In this way, multiple massage mechanisms can form multiple covering spaces, thereby massaging both legs of a passenger at the same time, or massaging the legs of multiple passengers at the same time, thereby improving massage comfort.

[0163] In some examples, the leg support device 210 is provided on the single seat 200, and the number of massage mechanisms may be two, so that the passenger's legs are massaged simultaneously by the two massage mechanisms.

[0164] In other examples, the leg support device 210 is provided on a row of multi-passenger seats 200, and the number of massage mechanisms can correspond to the number of seats in the multi-passenger seat 200, for example, two massage mechanisms can be provided for each seat. If the multi-passenger seat 200 is a three-passenger seat 200, six massage mechanisms can be provided on the leg support device 210 to massage the legs of three passengers simultaneously.

[0165] In some embodiments, multiple massage mechanisms are all in transmission connection with the first transmission shaft 142. The multiple massage mechanisms are driven simultaneously by the first transmission shaft 142, which optimizes the transmission structure, saves space and reduces costs compared to setting up multiple drive mechanisms.

[0166] For some specific examples, see Figures 2 to 4 , Figures 2 to 4 The leg support device 210 shown in FIG. 2 is provided with two massage mechanisms. A first motor 141 is positioned between the two massage mechanisms, and the output end of the first motor 141 is connected to a first transmission shaft 142. The length of the first transmission shaft 142 extends to both sides of the first motor 141, so that the first transmission structure 12 and the second transmission structure 13 of the two massage mechanisms are both connected to the first transmission shaft 142.

[0167] In some embodiments, see Figure 4 The leg support device 210 further includes a stabilizer bar 3. The plurality of massage mechanisms include a plurality of massage mechanism groups, each massage mechanism group including two massage mechanisms. In other words, two massage mechanisms form a group in the plurality of massage mechanisms, thereby dividing the plurality of massage mechanisms into a plurality of groups, and the plurality of massage mechanism groups are arranged along the width direction of the vehicle 1000.

[0168] In each group of massage mechanisms, the second massage assembly 20b of one massage mechanism is adjacent to the second massage assembly 20b of the other massage mechanism. Furthermore, one end of the stabilizing rod 3 is pivotally connected to the second massage assembly 20b of one massage mechanism, while the other end of the stabilizing rod 3 is pivotally connected to the second massage assembly 20b of the other massage mechanism. The stabilizing rod 3 connects the second massage assemblies 20b of the two massage mechanisms, improving stability between them.

[0169] In some examples, the stabilizing bar 3 and the two second massage assemblies 20b are both hingedly connected. The length of the stabilizing bar 3 and the connection position with the second massage assemblies 20b should ensure that the two second massage assemblies 20b on both sides of the stabilizing bar 3 do not interfere with each other during rotation.

[0170] In some embodiments, see Figure 3 、 Figure 4 The massage mechanism also includes a third massage component 20c, which is connected to the fixed plate 10. When the massage mechanism is in the deployed state, the third massage component 20c is located between the first massage component 20a and the second massage component 20b. When the massage mechanism is in the deployed state, the first massage component 20a and the second massage component 20b can massage both sides of the leg, while the third massage component 20c massages the side of the leg closest to the seat 200, thereby simultaneously massaging different parts of the leg and improving massage comfort.

[0171] In some examples, the third massage component 20c includes a massage air bag, which is connected to the fixed plate 10 through a fixed structure. The massage air bag is inflated and deflated to beat the legs, thereby achieving a massage effect.

[0172] In some embodiments, see Figure 3 、 Figure 4 、 Figure 5 The leg rest 210 is connected to the seat 200 via a four-way adjustment mechanism 4. The four-way adjustment mechanism 4 is slidably connected to the fixing plate 10 of the leg rest 210. The four-way adjustment mechanism 4 drives the leg rest 210 to move along the height direction of the vehicle 1000, thereby adjusting its height. The four-way adjustment mechanism 4 also drives the leg rest 210 to rotate, thereby adjusting its angle with the seat 200 to accommodate different sitting postures of passengers.

[0173] In some embodiments, see Figure 4The four-way adjustment structure includes a first bracket 41. The fixed plate 10 is connected to the first bracket 41 and can move relative to the first bracket 41 in the height direction of the seat 200. The four-way adjustment mechanism 4 also includes a third driving member 42 and a first transmission member 43. The first transmission member 43 is connected between the third driving member 42 and the fixed plate 10. The third driving member 42 drives the fixed plate 10 to move in the height direction of the seat 200 through the first transmission member 43.

[0174] In some examples, the third driving member 42 may be a motor, an air pump 51 , or the like.

[0175] In some embodiments, a first threaded hole is provided on the first bracket 41 ; the first transmission member 43 is a first screw rod, which passes through the first threaded hole and is screwed to the first threaded hole.

[0176] In this way, the first bracket 41 and the first transmission member 43 can be fixed by the cooperation between the first threaded hole and the first screw rod, and the thread and the screw rod also have a self-locking function. In addition, the structure of the threaded screw rod is relatively simple and easy to implement.

[0177] In some other embodiments, the first transmission member 43 may also be a gear rack structure, a worm gear and worm lifting structure, etc.

[0178] In some embodiments, the four-way adjustment mechanism 4 further includes a second bracket 46 adapted to be connected to the seat 200, with the upper end of the first bracket 41 being rotatably connected to the second bracket 46. The four-way adjustment mechanism 4 further includes a fourth drive member 44 and a second transmission member 45, with the second transmission member 45 connected between the fourth drive member 44 and the lower end of the first bracket 41. The fourth drive member 44 drives the first bracket 41 to rotate via the second transmission member 45.
