The legs of the passengers are prone to fatigue during riding of the vehicle for a long period of time because the legs of the passengers need to remain in the same posture for a long period of time.

In order to alleviate leg fatigue of passengers during riding, a seat of a vehicle is generally provided with a leg rest in the related art. The passenger can put the legs on the leg support, and the leg support can form support for the legs of the passenger, so that fatigue of the legs of the passenger is relieved.

However, the leg rest in the related art is generally a flat plate structure, and only supports the bottom of the legs of the passengers, so that the effect of relieving the fatigue of the legs of the passengers is limited.

In some related art, the leg rest may further be provided with a groove, and the passenger's leg may be placed in the groove, and the groove may support the passenger's leg and restrict the passenger's leg from sliding off the leg rest. Thus, the leg rest can improve the effect of relieving fatigue of the legs of the passengers. However, the size of the grooves formed in the existing leg support is usually fixed, and cannot be adjusted correspondingly according to the leg sizes of passengers, so that the effect of relieving fatigue of the legs of the passengers is poor.

Based on this, an embodiment of the present application provides an automobile seat, as shown in fig. 1, fig. 1 is a schematic structural diagram of an automobile seat 100 according to an embodiment of the present application, where the automobile seat 100 may include a seat body 1. The seat body 1 may be connected to a vehicle body to fix the car seat 100 inside the vehicle.

For example, as shown in fig. 1, the seat body 1 may include a seat bottom frame 11 and a connection bracket 12. The seat bottom frame 11 is connected to the connection bracket 12, and the connection bracket 12 is connected to the vehicle body, thereby fixing the seat body 1 inside the vehicle.

As shown in fig. 1, the car seat 100 may further include two seat leg rest 2, and both the seat leg rest 2 are connected to the seat body 1. In this way, the seat body 1 can provide a mounting position for the seat leg rest 2. The legs can be placed on the seat leg rest 2 when the passenger takes the vehicle, and the seat leg rest 2 can relieve the fatigue of the legs of the passenger.

For example, as shown in fig. 1, two seat leg rest 2 may be installed on the right side in fig. 1, and the position of the seat leg rest 2 exactly corresponds to the position of the lower leg of the passenger when the passenger sits on the seat body 1. This facilitates the passenger to put the legs on the seat leg rest 2.

As shown in fig. 2, fig. 2 is a second schematic structural view of an automobile seat 100 according to an embodiment of the present application, and two seat leg rests 2 are spaced apart. Thus, the two seat leg rests 2 can support the legs of the passenger separately, improving the comfort of the passenger riding.

In some embodiments, as shown in fig. 1, the seat body 1 may further include a rotation mechanism 13, the rotation mechanism 13 being coupled to the seat bottom frame 11. The seat leg rest 2 is connected to a side of the swivel mechanism 13 remote from the seat bottom frame 11. Thus, the rotation mechanism 13 can drive the seat leg rest 2 to rotate, thereby adjusting the angle of the seat leg rest 2 so that a passenger can comfortably put the legs on the seat leg rest 2. It should be noted that, how the rotation mechanism 13 drives the seat leg rest 2 to rotate is a technical means well known to those skilled in the art, so that the description thereof is omitted herein.

As shown in fig. 2, the seat leg rest 2 includes a bottom support 21 and two side supports 22. The bottom support 21 is connected to the seat body 1. In this way, the bottom support 21 may be used to support the legs of the occupant.

The two side supports 22 are located on opposite sides of the bottom support 21, respectively, and are rotatably connected to the bottom support 21. In this way, the two side supports 22 can be rotated. Since the two side supports 22 are located at opposite sides of the bottom support 21, respectively, the two side supports 22 can be rotated to positions corresponding to each other, thereby forming support for the legs of the passenger from both sides.

In some embodiments, as shown in fig. 3, fig. 3 is a schematic structural diagram of a seat leg rest 2 according to an embodiment of the present application, and the seat leg rest 2 may further include a driving mechanism 23. The driving mechanism 23 is connected to the two side supporting members 22, and is used for driving the two side supporting members 22 to rotate relative to the bottom supporting member 21, so that the two side supporting members 22 and the bottom supporting member 21 form an enclosed space for partially accommodating the legs.

Thus, the passenger does not need to manually rotate the side support 22, and the seat leg rest 2 is highly practical. When the driving mechanism 23 stops moving, the positions of the two side supports 22 are also fixed. The passenger can adjust the position of the side support 22 according to the actual demand so that the side support 22 can stay in place. After the legs of the passenger are put into the surrounding space surrounded by the two side supports 22 and the bottom support 21, the side supports 22 can provide moderate supporting force for the legs of the passenger, thereby improving the comfort of the legs of the passenger.

Illustratively, as shown in FIG. 2, two side supports 22 are located on opposite sides of the bottom support 21 along the first direction X, respectively. The rotation axes of the two side supports 22 are parallel to a second direction Y, which is mutually perpendicular to the first direction X and parallel to the bottom support 21. In this way, the two side supports 22 can be turned in directions approaching each other, thereby forming an enclosed space with the bottom support 21.

In order to improve the comfort of the seat leg rest 2, in some embodiments, as shown in fig. 4, fig. 4 is a schematic diagram of a second structure of the seat leg rest 2 according to an embodiment of the present application, the driving mechanism 23 may be located on a side of the bottom support 21 facing away from the surrounding space, and connected to the bottom support 21.

Since the drive mechanism 23 can be located on the side of the bottom support 21 facing away from the enclosure, the passenger will not collide with the drive mechanism 23 when placing the legs in the enclosure, and the comfort and safety of the seat leg rest 2 is high.

As the drive mechanism 23 is connected to the bottom support 21. The bottom support 21 may provide a mounting location for the drive mechanism 23.

In some embodiments, as shown in fig. 5, fig. 5 is a third schematic structural view of the leg rest 2 according to the embodiment of the present application, and the driving mechanism 23 includes a driving motor 231 and a driving assembly 232. The driving motor 231 is provided on the bottom supporter 21.

For example, as shown in fig. 4, the driving motor 231 may be disposed at a side of the bottom supporter 21 facing away from the surrounding space.

As shown in fig. 5, the driving assembly 232 may be connected to an output end of the driving motor 231 and to the two side supporters 22. Thus, the driving motor 231 may drive the driving assembly 232 to move, and the driving assembly 232 may drive the two side supporting pieces 22 to move, so as to rotate the two side supporting pieces 22.

In some embodiments, as shown in fig. 5, the drive assembly 232 includes a transmission assembly 2321, two first links 2322, and two second links 2323. The transmission assembly 2321 is connected with the output end of the driving motor 231 and is used for moving under the driving of the driving motor 231. One end of each of the two first connecting members 2322 is rotatably connected to the transmission assembly 2321.

For example, the transmission assembly 2321 may be driven by the driving motor 231 to move along the first direction X. The two first connection members 2322 may also move along the first direction X under the driving of the transmission assembly 2321, and the two first connection members 2322 may rotate around the connection position between themselves and the transmission assembly 2321 during the movement process.

As shown in fig. 5, two second connection members 2323 are respectively connected to one side supporter 22. A second link 2323 is also rotatably coupled to the other end of a first link 2322. The rotation axes of both ends of the first link 2322 are parallel to the rotation axis of the side supporter 22.

In this way, rotation may occur during movement of the two first links 2322 in the first direction X, thereby pushing the two second links 2323 to rotate about the side support 22 axis of rotation. The two second connecting members 2323 can drive the side supporting members 22 to rotate during rotation, so that the positions of the side supporting members 22 can be adjusted, the side supporting members 22 can stay at proper positions, and the side supporting members 22 can provide moderate supporting force for the legs of the passengers, so that the comfort level of the legs of the passengers is improved.

In some embodiments, as shown in fig. 5, the transmission assembly 2321 may include a first transmission gear 23211, a second transmission gear 23212, a lead screw 23213, and two movers 23214. The first transmission gear 23211 is sleeved on the output shaft of the driving motor 231. Thus, the rotation of the driving motor 231 may drive the first transmission gear 23211 to rotate.

The screw 23213 penetrates through the second transmission gear 23212 and is connected with the second transmission gear 23212. The second transfer gear 23212 meshes with the first transfer gear 23211. Thus, the first transmission gear 23211 can rotate to drive the second transmission gear 23212 to rotate, and the second transmission gear 23212 can drive the screw 23213 to rotate.

The threads on the two ends of the screw 23213 are opposite. The two moving members 23214 are sleeved at two ends of the screw 23213 and are in threaded connection with the screw 23213. Thus, the two moving members 23214 may move in opposite directions during rotation of the screw 23213.

A moving member 23214 is coupled to the other end of a first coupling member 2322. Thus, the two moving members 23214 may drive the two first connecting members 2322 to move in opposite directions during the movement of the two moving members in opposite directions.

For example, as shown in fig. 4, during the movement of the two first connecting members 2322 in the direction away from each other, the two second connecting members 2323 may be pushed to rotate in the direction approaching each other, so as to drive the two side supporting members 22 to rotate in the direction approaching each other. As the two side supports 22 are rotated in directions approaching each other, the enclosure space formed by the two side supports 22 and the bottom support 21 decreases.

During the movement of the two first connecting members 2322 in the direction approaching each other, the two second connecting members 2323 may be pulled to rotate in the direction separating from each other, so as to drive the two side supporting members 22 to rotate in the direction separating from each other. As the two side supports 22 are rotated in the directions away from each other, the enclosure space formed by the two side supports 22 and the bottom support 21 increases.

According to the above, the passenger can control the rotation direction of the driving motor 231 according to his/her own needs, thereby controlling the size of the enclosed space formed by the two side supports 22 and the bottom support 21 so that the two side supports 22 can be fitted to the lower legs of the passenger. In this way, the comfort level of the passengers riding can be improved.

In other embodiments, as shown in fig. 5, the number of first connectors 2322 may be four. Two of the four first connection members 2322 are connected to two of the moving members 23214 and two of the second connection members 2323, respectively. The two first connection members 2322 of the same group are disposed at intervals along a direction parallel to the extending direction of the first connection members 2322.

In some embodiments, as shown in fig. 5, the side support 22 is formed with a plurality of connection portions 221 disposed at intervals. The second connection member 2323 penetrates the plurality of connection portions 221 and is connected to the plurality of connection portions 221. The connection 221 may provide a mounting location for the second connection 2323, facilitating connection of the second connection 2323 with the side support 22.

As shown in fig. 6, fig. 6 is a schematic structural diagram of a leg rest 2 according to an embodiment of the present application, and two connection portions 221 are formed on each side support 22. Along the extending direction of the second connection member 2323, the two connection portions 221 are disposed at intervals. The two ends of the second connection member 2323 respectively penetrate through the two connection portions 221, and the two connection portions 221 can limit the two ends of the second connection member 2323, so that the second connection member 2323 is connected with the side support member 22.

In some embodiments, as shown in fig. 5, the drive mechanism 23 may further include a third link 233. The third connecting piece 233 is connected to the bottom supporting piece 21 and sleeved on the screw 23213. Thus, third link 233 may provide an installation location for lead screw 23213.

The third link 233 is rotatably coupled to the screw 23213. Thus, the third link 233 does not affect the normal rotation of the screw 23213.

Illustratively, as shown in FIG. 5, the third link 233 is coupled to the bottom support 21 on a side of the bottom support 21 facing away from the enclosed space. The number of the third links 233 may be two, and the two third links 233 are spaced apart along the extension direction of the screw 23213. Two third connectors 233 may be respectively sleeved at both ends of the screw 23213.

It is to be understood that the number of the third connecting members 233 may be set according to actual use requirements, for example, the number of the third connecting members 233 may be three or four, so long as it is ensured that the third connecting members 233 do not affect the movement of the first connecting member 2322 along the screw 23213.

In other embodiments, as shown in fig. 7, fig. 7 is a schematic structural diagram of another car seat 100 according to an embodiment of the present application, and the seat body 1 may further include a mounting member 14. The mounting member 14 is connected to the seat bottom frame 11.

Illustratively, as shown in FIG. 7, the mounting member 14 may be rotatably coupled to the seat bottom frame 11 by a rotation mechanism 13. The bottom support 21 is connected to the mounting member 14. In this way, the mounting 14 may provide a mounting location for the seat leg rest 2.

As shown in fig. 7, the mounting member 14 is located on a side of the bottom support 21 away from the surrounding space, and is connected to the bottom support 21. In this way, the legs of the passenger do not interfere with the mounting member 14 when placed on the bottom support member 21.

At least a portion of the mounting member 14 is disposed opposite the four side support members 22. The drive mechanism 23 may also include a plurality of support airbags 234. The plurality of support cells 234 are disposed between the four side support members 22 and the mounting member 14, respectively. A plurality of support cells 234 are connected to the mounting member 14 on one side and to the side support members 22 on the other side. The plurality of support cells 234 are configured to be inflated to respectively rotate the four side support members 22 relative to the bottom support member 21.

The volume of the support airbag 234 increases after inflation, and as the volume of the support airbag 234 increases, the support airbag 234 can push the side support members 22 to rotate relative to the bottom support member 21, and the two side support members 22 of each seat leg rest 2 move in directions approaching each other under the pushing of the support airbag 234, so that the enclosed space formed by the two side support members 22 of each seat leg rest 2 and the bottom support member 21 decreases.

The volume of the support airbag 234 after the gas is exhausted decreases, and as the volume of the support airbag 234 decreases, the support airbag 234 drives the side support members 22 to rotate, and the two side support members 22 of each seat leg rest 2 are driven by the support airbag 234 to rotate in a direction away from each other, so that the surrounding space formed by the two side support members 22 and the bottom support member 21 of each seat leg rest 2 increases.

The passenger can adjust the setting angle of the two side supports 22 of each seat leg rest 2 by inflating or deflating the support airbag 234 so that the two side supports 22 of each seat leg rest 2 can comfortably support the legs of the passenger.

It should be noted that, in some embodiments, the driving mechanism 23 may further include an electric inflator (not shown in the drawings), and the electric inflator is connected to the support airbag 234 through a pipe for inflating the support airbag 234.

In some embodiments, each support airbag 234 may be configured with a separate electric inflator. In this way, the occupant can control the inflation and deflation of each support airbag 234 according to actual needs so that the side supports 22 can conform to the occupant's legs.

Illustratively, the electric inflator may be an electric inflator with inflation and deflation functions. In this way, the occupant can control the inflation and deflation of the support airbag 234 by activating the various functions of the electric inflator.

Or the electric inflator pump can also be selected to have the inflating function only. The support airbag 234 may further be provided with an electric valve, so that a passenger can start the electric inflator to inflate the support airbag 234, and control the electric valve to open to discharge air in the support airbag 234.

It should be noted that, how to control the operation of the electric inflator and control the opening and closing of the electric valve are all technical means well known to those skilled in the art, and are not repeated in the present application.

In order to improve the comfort of the passenger, in some embodiments, as shown in fig. 8, fig. 8 is a schematic structural diagram of another seat leg rest 2 according to an embodiment of the present application, and the seat leg rest 2 may further include a plurality of massage air bags 24. A plurality of massage air bags 24 are provided at one side of the two side supports 22.

As shown in fig. 8, when the two side supports 22 are rotated to the opposite state, the plurality of massage air bags 24 may be located at the sides where the two side supports 22 are close to each other. In this way, the plurality of massage air bags 24 can press and massage the legs of the passenger, thereby relieving fatigue in riding the passenger and improving comfort of riding the passenger.
