[0047] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0049] like Figures 1 to 6As shown, the present disclosure provides a leg rest mechanism for supporting a leg rest on a vehicle seat and driving the leg rest to be folded or stowed, or to be opened to support the calves of passengers.

[0050] Specifically, the leg support mechanism includes a base support 1, a support support 2, a drive assembly 3 and a lifting support 4. Among them, the base support 1 is connected to the body floor of the vehicle (not shown in the figure). The support support 2 is connected to the base support 1. The drive assembly 3 includes a drive support 31 and a lifting structure 32 arranged on the drive support 31, and the drive support 31 is connected to the support support 2. The lifting support 4 is rotatably connected to the drive support 31, and a transmission member 42 is arranged on the lifting support 4, and the transmission member 42 is rotatably connected to the lifting structure 32, and the lifting structure 32 drives the transmission member 42 to make the lifting support 4 rotate relative to the drive support 31. The supporting plate frame 5 is arranged on the lifting support 4. The supporting plate frame 5 is used to support the leg support.

[0051] It can be understood that by setting up the base bracket 1, the supporting bracket 2, the driving assembly 3, the lifting bracket 4 and the supporting plate frame 5, and driving the transmission member 42 through the lifting structure 32 to rotate the lifting bracket 4 relative to the driving bracket 31, the lifting bracket 4 and the supporting plate frame 5 can be rotated down or rotated up, thereby realizing the folding or opening of the leg rest and realizing the stable rotation function of the leg rest.

[0052] Moreover, the base bracket 1 is connected to the vehicle body floor, so that the base bracket 1 can be arranged below the seat bracket, which can save space in front of the seat, so that the leg support mechanism is suitable for the rear seats of the vehicle, such as the rear seats of a five-seat vehicle, so that the rear seats of the five-seat vehicle can also be designed with leg supports. Among them, the seat cushions of the rear seats of the five-seat vehicle are long seat cushions, usually three-seat seat cushions. Of course, the leg support mechanism is usually suitable for the front seats or rear seats of other models.

[0053] It should be noted that in the prior art, the base bracket 1 of the leg rest mechanism is installed on the seat bracket, so that the base bracket 1 extends to the front side of the seat. The space in front of the rear seat of the vehicle is relatively small, so it is not suitable for installation on the leg rest mechanism. Directly connecting the base bracket 1 to the vehicle body floor can not only reduce the space occupied in front of the seat, but also be suitable for the rear seat, and provide support for the leg rest mechanism through the body floor. Combined with the stable structure of the leg rest mechanism itself, the leg rest can be stably rotated and extended.

[0054] like Figures 1 to 4As shown, the leg support mechanism further includes an elastic member 7, one end of which is connected to the base support 1, and the other end is connected to the lifting support 4. When the lifting support 4 rotates relative to the driving support 31 and lifts upward, the elastic member 7 is stretched. The lifting of the lifting support 4 upward means that the end of the lifting support 4 away from the driving support 31 gradually moves upward in the vertical direction as the lifting support 4 rotates.

[0055] It can be understood that when the lifting bracket 4 rotates relative to the driving bracket 31 and is lifted upward under the drive of the lifting structure 32, the elastic member 7 can be gradually stretched, so that the elastic force of the elastic member 7 applies a force to the lifting bracket 4 to resist the drive of the lifting structure 32, so that the lifting bracket 4 can move stably and avoid noise and shaking during the lifting process.

[0056] like Figures 1 to 3 As shown, the base bracket 1 comprises a left bracket 12, a right bracket 13, a base cross plate 14 and a base cross bar 11, the base cross plate 14 is connected to the left bracket 12 and the right bracket 13, the left bracket 12 and the right bracket 13 are both provided with support protrusions, and the base cross bar 11 is connected to the two support protrusions. The elastic member 7 is connected to the base cross bar 11, and the support bracket 2 is connected to the base cross bar 11.

[0057] By raising the base cross bar 11 to a certain height through the support protrusions on the left bracket 12 and the right bracket 13, the length of the support bracket 2 or the driving bracket 31 can be reduced, thereby avoiding the problem of structural instability caused by the excessive length of the support bracket 2 or the driving bracket 31.

[0058] The left bracket 12 and the right bracket 13 are used to connect the vehicle body floor. Specifically, the left bracket 12 and the right bracket 13 are fixed on the vehicle body floor by screws.

[0059] For example, in a specific implementation, referring to Figure 3 A spring hook frame 111 is provided on the base cross bar 11, and one end of the elastic member 7 is connected to the spring hook frame 111. Alternatively, the elastic member 7 can also be directly welded to the base cross bar 11.

[0060] It should be noted that the above-mentioned left bracket 12 and right bracket 13 are connected to the base cross bar 11 by welding, and the left bracket 12 and right bracket 13 are connected to the base cross plate 14 by welding, that is to say, the left bracket 12, the right bracket 13, the base cross plate 14 and the base cross bar 11 are connected by welding to form the base bracket 1, thereby ensuring that the base bracket 1 has good structural strength and rigidity.

[0061] like Figures 1 to 3As shown, the driving bracket 31 includes a left reinforcing plate 311, a right reinforcing plate 312 and a driving cross bar 313 connected between the left reinforcing plate 311 and the right reinforcing plate 312. The left reinforcing plate 311 and the right reinforcing plate 312 are both connected to the supporting bracket 2, and the lifting structure 32 is arranged on the driving cross bar 313. Among them, the left reinforcing plate 311 and the right reinforcing plate 312 are both inclined upward relative to the horizontal direction, and the lifting bracket 4 is rotatably connected to the left reinforcing plate 311 and the right reinforcing plate 312.

[0062] With such arrangement, the height of the lifting bracket 4 in the direction of the seat height can be raised by the left reinforcing plate 311 and the right reinforcing plate 312, so that the lifting bracket 4 can reach the height of supporting the leg rest, and after the lifting bracket 4 rotates relative to the driving bracket 31, the leg rest reaches the set height to support the legs of the passenger.

[0063] Further, in some embodiments, the lifting structure 32 includes a second drive motor assembly 321 and a second lead screw 322. The second drive motor assembly 321 is mounted on the driving cross bar 313 through a second mounting bracket 323, the second lead screw 322 is connected to the second drive motor assembly 321, the second lead screw 322 is tilted upward relative to the horizontal direction, and one end of the second lead screw 322 is rotatably connected to the transmission member 42, and the second drive motor assembly 321 is used to drive the second lead screw 322 to move in its extension direction to drive the lifting bracket 4 to rotate relative to the driving bracket 31.

[0064] It can be understood that when the second lead screw 322 moves downward in its extending direction, the transmission member 42 can drive the lifting bracket 4 to rotate upward relative to the driving bracket 31, so that the lifting bracket 4 drives the leg rest to open upward. When the second lead screw 322 moves downward in its extending direction, the transmission member 42 can drive the lifting bracket 4 to rotate downward relative to the driving bracket 31, so that the lifting bracket 4 drives the leg rest to fold downward.

[0065] It should be noted that the second drive motor assembly is rotatably mounted on the second mounting bracket 323 and can swing up and down relative to the second mounting bracket 323. In this way, the second lead screw 322 can be driven to swing up and down while driving the second lead screw 322 to move in its extension direction, which can increase the kinematic pair. In this process, the second lead screw 322 does not rotate around its own axis, so that the second drive motor assembly drives the lifting bracket 4 to rotate upward or downward relative to the driving bracket 31 by driving the second lead screw 322 to move on its extension and rotating itself. Among them, the second drive motor assembly rotates around an axis extending along the extension direction of the driving cross bar 313.

[0066] The second drive motor assembly 321 includes a second drive motor and a gear set, one gear in the gear set is meshed with the second lead screw 322, and the second drive motor drives the second lead screw 322 to move in its extension direction through the gear set.

[0067] Optionally, in some embodiments, the lifting structure 32 may include a second drive motor assembly and a rack. The second drive motor assembly includes a second drive motor and a gear, and the second drive motor drives the gear to rotate. The second drive motor assembly is mounted on the driving cross bar, the rack is meshed with the gear, the rack is tilted upward relative to the horizontal direction, and one end of the rack is rotatably connected to the transmission member, and the second drive motor drives the rack to move in its extension direction through the gear to drive the lifting bracket to rotate relative to the driving bracket through the transmission member.

[0068] like Figures 1 to 3 As shown, the support bracket 2 includes a left support plate 21 and a right support plate 22, both of which are connected to the base bracket 1, the left support plate 21 is connected to the left reinforcing plate 311, and is stacked with the left reinforcing plate 311, and the right support plate 22 is connected to the right reinforcing plate 312, and is stacked with the right reinforcing plate 312. Wherein, the left support plate 21 and the right support plate 22 are both connected to the base cross bar 11.

[0069] Specifically, the supporting bracket 2 and the driving bracket 31 jointly provide stable support for the driving bracket 31 , thereby enhancing the supporting effect on the lifting bracket 4 .

[0070] Furthermore, the left reinforcing plate 311 is located below the supporting left plate 21 , and the right reinforcing plate 312 is located below the supporting right plate 22 , so that the lifting bracket 4 and the driving bracket 31 jointly provide support for the lifting bracket 4 , which is beneficial to improve the stability of the support for the lifting bracket 4 .

[0071] Furthermore, the support bracket 2 further includes a support transverse plate 23 , which is connected to the support right side plate 22 and the support left side plate 21 , and is used to support the seat cushion 10 of the seat.

[0072] Specifically, in the front-to-back direction of the seat, the support cross plate 23 is located in front of the base cross bar 11, and the driving cross bar 313 is located between the support cross plate 23 and the base cross bar 11; in the height direction of the seat, the support cross plate 23 is located above the base cross bar 11, and the driving cross bar 313 is located between the support cross plate 23 and the base cross bar 11. That is to say, the base cross bar 11, the driving cross bar 313 and the support cross plate 23 are gradually raised toward the front of the seat, so as to facilitate supporting the seat cushion 10.

[0073] like Figure 3 and Figure 4As shown, the lifting bracket 4 includes a lifting plate body and a lifting cross bar connected to each other, and the lifting plate body is rotatably connected to the driving bracket 31. Among them, the transmission member 42 is connected to the lifting cross bar, and the connection method can be screw connection, welding, etc.

[0074] Specifically, the lifting plate body is connected to the left reinforcing plate 311 and the right reinforcing plate 312 respectively through two step bolts 44. The two step bolts 44 are threadedly connected to the left reinforcing plate 311 and the right reinforcing plate 312 respectively, and the lifting plate body is sleeved on the step bolts 44 and can rotate around the step bolts 44.

[0075] Further, a spring hook plate 43 is provided on the lifting bracket 4, and one end of the elastic member 7 is connected to the spring hook plate 43. Specifically, the spring hook plate 43 is connected to the lifting cross bar. And preferably, the spring hook plate 43 is fixed to the lifting cross bar by welding.

[0076] Reference Figures 1 to 4 The above-mentioned supporting plate frame 5 is slidably arranged on the lifting bracket 4. The leg support mechanism also includes a sliding drive structure 6, which is arranged on the lifting bracket 4 or the supporting plate frame 5 to drive the supporting plate frame 5 to slide relative to the lifting bracket 4.

[0077] It can be understood that the supporting plate frame 5 is slidably set on the lifting bracket 4. Through the sliding drive structure 6, the supporting plate frame 5 can be driven to slide relative to the lifting bracket 4 after the lifting bracket 4 is rotated and lifted, so that the leg rest can be extended or contracted to realize the stable telescopic function of the leg rest.

[0078] Reference Figure 3 and Figure 4 The above-mentioned supporting plate frame 5 is a plate-shaped structure, which can increase the supporting area of ​​the leg rest, thereby providing stable support for the leg rest.

[0079] Reference Figure 3 and Figure 4 The lifting bracket 4 is provided with a first slide rail 41, and the supporting plate frame 5 is provided with a second slide rail 51. The second slide rail 51 and the first slide rail 41 cooperate with each other, so as to realize the sliding cooperation between the supporting plate frame 5 and the lifting bracket 4, and realize the guidance of the supporting plate frame 5 when sliding relative to the lifting bracket 4. The first slide rail 41 is provided on the lifting plate body of the lifting bracket 4.

[0080] For example, in a specific implementation, referring to Figure 3 and Figure 4 The above-mentioned first slide rails 41 and second slide rails 51 are both provided with two, and the two first slide rails 41 and the two second slide rails 51 cooperate with each other one by one, so as to further improve the stability of the lifting bracket 4 and the supporting plate frame 5 when they slide relative to each other.

[0081] Reference Figure 4In some embodiments, the sliding drive structure 6 includes a first driving motor assembly 61, a first lead screw 62 and a slider 63. The first driving motor assembly 61 is installed on the supporting plate frame 5 and is connected to the first lead screw 62. The first lead screw 62 extends along the sliding direction of the supporting plate frame 5. The slider 63 is arranged on the lifting bracket 4 and is threadedly connected to the first lead screw 62.

[0082] Specifically, the first drive motor assembly 61 is mounted on the supporting plate frame 5 through the first mounting bracket 64. Moreover, the first drive motor assembly 61 and the first lead screw 62 are both located on the side of the supporting plate frame 5 facing the lifting bracket 4.

[0083] Among them, the first drive motor assembly 61 drives the first lead screw 62 to rotate around its axis, and the slider 63 is arranged on the lifting bracket 4 and is threadedly connected to the first lead screw 62. Since the slider 63 is fixedly arranged on the lifting bracket 4, the slider 63 cannot move, so that the first lead screw 62 and the first drive motor assembly 61 move in the extension direction of the first lead screw 62, thereby realizing the sliding of the supporting plate frame 5 relative to the lifting bracket 4. It can be understood that when the first drive motor assembly 61 drives the first lead screw 62 to rotate in different directions, the moving directions of the supporting plate frame 5 relative to the lifting bracket 4 are different.

[0084] It should be noted that the sliding block 63 can be fixed on the lifting bracket 4 by welding or screwing, and this embodiment does not impose any specific limitation.

[0085] Optionally, in some other embodiments, the first drive motor assembly 61 may be installed on the lifting bracket 4, and the slider 63 may be arranged on the supporting plate frame 5. The slider 63 is fixedly connected to the supporting plate frame 5, and the first drive motor assembly 61 drives the slider 63 through the first lead screw 62 to drive the supporting plate frame 5 to move.

[0086] The working process of the leg support mechanism will be described in detail below.

[0087] like Figure 1 As shown, at this time, the lifting bracket 4 and the supporting plate frame 5 are both in a folded state, and the leg support is also in a folded state. When the leg support needs to be lifted, the second drive motor assembly 321 drives the second lead screw 322 to move upward in its extension direction, and the lifting bracket 4 is rotated upward relative to the drive bracket 31 to a desired position through the transmission member 42, as shown in FIG. Figure 5 When the leg support needs to be stretched, the first drive motor assembly 61 drives the first lead screw 62 to rotate in the positive direction, thereby driving the support plate frame 5 to move away from the drive bracket 31 until it moves to the desired position, as shown in FIG. Figure 2 and Figure 6 shown.

[0088] It should be noted that in Figure 2 and Figure 6 In the state shown, when the leg support needs to be folded, the first drive motor assembly 61 first drives the first lead screw 62 to rotate in the opposite direction, thereby driving the support plate frame 5 to move toward the driving bracket 31, so as to achieve the folding of the support plate frame 5 and the lifting bracket 4. Subsequently, the second drive motor assembly 321 drives the second lead screw 322 to move downward in its extension direction, and the lifting bracket 4 is rotated downward relative to the driving bracket 31 to the initial position (such as Figure 1 ), to achieve the folding of the leg rest.

[0089] The present disclosure also provides a seat, such as Figure 7 and Figure 8 As shown, the seat comprises the above-mentioned leg support mechanism and a seat cushion 10. The seat cushion 10 comprises a seat cushion portion and a leg support portion, the leg support portion can rotate relative to the seat cushion portion, and the seat cushion portion is provided with a first slot.

[0090] The base bracket 1 includes a base cross bar 11, and the support bracket 2 includes a support cross plate 23. The support cross plate 23 is located at the front side of the base cross bar 11 in the front-rear direction of the seat, and is located above the base cross bar 11 in the seat height direction. The base cross bar 11 is clamped in the first clamping groove, and the support cross plate 23 is supported at the corner of the seat cushion part and the leg support part. The leg support part is connected to the supporting plate frame 5.

[0091] The leg support mechanism is installed on the vehicle body floor through a base bracket 1, the base cross bar 11 is clamped with the first slot, the support cross plate 23 supports the corners of the seat cushion part and the leg support part, and the leg support part is connected to the supporting plate frame 5, thereby realizing the coordination between the leg support mechanism and the seat cushion 10 of the seat, stably supporting the seat cushion 10 through the leg support mechanism, and being able to drive the leg support part to move.

[0092] In this way, during installation, the leg rest mechanism can be first installed on the vehicle body floor through the base bracket 1, and then the seat cushion 10 can be installed, so that the base cross bar 11 and the first slot are locked, and the supporting cross plate 23 is supported at the corner of the seat cushion part and the leg rest part, which is convenient for the installation of the seat.

[0093] It should be noted that, since the base bracket 1 is fixed on the vehicle body floor instead of being fixed on the seat bracket, it does not occupy the front space of the seat, so that the leg rest mechanism is suitable for the rear seats of the five-seater vehicle, so that the rear seats of the five-seater vehicle can also be designed with leg rests. Among them, the seat cushions of the rear seats of the five-seater vehicle are long seat cushions, usually three-seat seat cushions. Of course, the leg rest mechanism is usually suitable for the front seats or rear seats of other models.

[0094] Further, refer to Figure 8The driving bracket 31 further includes a driving crossbar 313, which is located between the base crossbar 11 and the supporting cross plate 23 in the front-rear direction of the seat, and between the base crossbar 11 and the supporting cross plate 23 in the seat height direction. The seat cushion portion is further provided with a second slot, in which the driving crossbar 313 is clamped.

[0095] The cooperation between the driving cross bar 313 and the second slot further improves the stability of the cooperation between the seat cushion and the leg support mechanism.

[0096] It should be noted that the first card slot and the second card slot are both arranged on the EPP (Expanded polyproplene, high foamed polypropylene) structure of the seat cushion 10 .

[0097] The present disclosure also provides a vehicle, including the above-mentioned seat. The vehicle has the technical effects of the above-mentioned seat embodiment, which will not be described in detail here. The vehicle is a five-seat model, a seven-seat model, etc., which is not specifically limited here.
