[0033] This application provides a seat footrest structure and a vehicle, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0034] Reference Figure 1 and Figure 2 One embodiment of this application provides a seat footrest structure 100 for mounting on a seat 200, such as in a vehicle. As an example, the seat footrest structure 100 may be mounted on a front seat 200, and the seat footrest structure 100 may be positioned near the front seat 200 towards the rear seat 200 for use by rear passengers.

[0035] Reference Figure 1 and Figure 2 The seat footrest structure 100 may include a support member 1 and a drive assembly 2. The drive assembly 2 is disposed on the seat 200. The support member 1 is connected to the drive assembly 2. The drive assembly 2 is used to drive the support member 1 to move in the height direction Z of the seat 200 to adjust the height of the support member 1.

[0036] Specifically, the support component 1 can be square, circular, or other shapes, and can be designed according to actual needs. One side of the support component 1 serves as the bearing surface, and the other side can be connected to the drive assembly 2. The bearing surface of the support component 1 can be used to support the user's feet, legs, or other body parts, and can also be used to support other items. The material of the support component 1 can be plastic, metal, or composite materials. In some embodiments, the material of the support component 1 is a lightweight, high-strength material, such as aluminum alloy or carbon fiber composite material, which ensures that the support component 1 has sufficient support strength while reducing its weight.

[0037] Reference Figure 2 and Figure 3 The drive assembly 2 may include a drive mechanism 21 and a transmission mechanism 22. The drive mechanism 21 is disposed on the seat 200 and can be connected to the frame of the seat 200 by bolts, welding, or other fixing methods to ensure the stability of the drive process. The drive mechanism 21 is, for example, a motor, such as a DC motor, a stepper motor, or a servo motor. In some embodiments, the drive mechanism 21 is a motor with a self-locking function, which can maintain its position after the support member 1 is adjusted to the required height to prevent accidental movement. The output end 211 of the drive mechanism 21 is connected to the transmission mechanism 22, which is connected to the support member 1. The transmission mechanism 22 can transmit the power of the drive mechanism 21 to the support member 1, so that the drive mechanism 21 drives the support member 1 to rise or fall through the transmission mechanism 22, that is, the drive mechanism 21 drives the support member 1 to move in the height direction Z of the seat 200 through the transmission mechanism 22 to adjust the height of the support member 1.

[0038] Reference Figure 2 , Figure 4 and Figure 5 The seat 200 has a bottom 210 and a top 220 in the height direction Z of the seat 200. The drive assembly 2 can drive the support member 1 to move between the bottom 210 and the top 220 of the seat 200 to adjust the height of the support member 1. As an example, when the drive assembly 2 drives the support member 1 closer to the bottom 210 of the seat 200, the support member 1 can function as a footrest (e.g., Figure 4As shown, the support member 1 can be used to support the user's feet or legs, etc. When the drive assembly 2 drives the support member 1 to the top 220 near the seat 200, the support member 1 can function as a table (e.g., Figure 5 As shown, the support component 1 can be used to support items. That is to say, by adjusting the height of the support component 1 through the drive component 2, the support component 1 can be used not only as a footrest but also as a table. In other words, the support component 1 can meet different usage scenarios, satisfying the needs of users of different heights and increasing the usage scenarios of the support component 1.

[0039] In this application, the drive mechanism 21 drives the support member 1 to rise or fall through the transmission mechanism 22 to adjust the height of the support member 1. This not only allows the height of the support member 1 to be adjusted according to the user's height, thereby meeting the needs of different users and improving the user experience, but also allows the drive component 2 to automatically adjust the height of the support member 1. This improves the adjustment accuracy and facilitates user operation, further enhancing the user experience. Furthermore, the drive component 2 can drive the support member 1 to move between the bottom 210 and the top 220 of the seat 200. The support member 1 can be used not only as a footrest but also as a table, thus meeting the needs of different usage scenarios.

[0040] In some embodiments, refer to Figure 2 and Figure 3 The transmission mechanism 22 may include a first transmission member 221, a second transmission member 222, and a connecting member 223. The first transmission member 221 is connected to the output end 211 of the drive mechanism 21. The first transmission member 221 can be fixed to the output end 211 of the drive mechanism 21 by welding or bolting to ensure the power transmission efficiency of the drive mechanism 21. The two ends of the connecting member 223 are respectively connected to the second transmission member 222 and the carrier member 1 by welding, bolting, riveting, or hinge. The drive mechanism 21 drives the second transmission member 222 to move through the first transmission member 221, and the second transmission member 222 drives the carrier member 1 to move through the connecting member 223. As an example, when the drive mechanism 21 is working, its output end 211 drives the first transmission member 221 to rotate or move, the first transmission member 221 drives the second transmission member 222 to move, and the second transmission member 222 drives the carrier member 1 to rise or fall through the connecting member 223.

[0041] In some examples, the first transmission component 221 can be a gear, and the second transmission component 222 can be a rack, with the first transmission component 221 and the second transmission component 222 meshing with each other. The gear is fixedly mounted on the output end 211 of the drive mechanism 21, and the rack extends along the height direction Z of the seat 200. When the drive mechanism 21 drives the gear to rotate, the gear drives the rack to move along the height direction Z, thereby driving the carrier component 1 to rise or fall through the connecting member 223. The gear and rack transmission method has the advantages of high transmission efficiency, accurate transmission ratio, reliable operation, and long service life, and can ensure the smoothness and accuracy of the adjustment process of the carrier component 1. Of course, in other embodiments, the first transmission component 221 and the second transmission component 222 can also adopt other transmission forms, such as screw and nut drive, belt drive, or chain drive.

[0042] In some embodiments, refer to Figure 2 and Figure 3 The seat footrest structure 100 may further include a guide member 3, a sliding member 4, and a support assembly 5. The guide member 3 is connected to the seat 200 via the support assembly 5. The guide member 3 may extend along the height direction Z of the seat 200, and may be, for example, a long strip-shaped guide rail or a groove structure. One end of the sliding member 4 is connected to the support member 1, and the other end of the sliding member 4 is slidably connected to the guide member 3. When the support member 1 rises or falls, the sliding member 4 slides along the guide member 3, providing guidance and support for the support member 1, preventing the support member 1 from shifting or swaying during movement, thereby improving the stability and accuracy of the movement of the support member 1.

[0043] In some embodiments, the guide member 3 can also restrict the sliding member 4 from displacing in the thickness direction Y of the seat 200, that is, the guide member 3 can restrict the sliding member 4 from displacing in the front-back direction, thereby restricting the carrier member 1 from displacing in the front-back direction and the transmission mechanism 22 from displacing in the front-back direction, thereby ensuring the stability of the relative position of the first transmission member 221 and the second transmission member 222, and ensuring the stability and accuracy of the driving force transmission of the drive mechanism 21.

[0044] In some embodiments, the transmission mechanism 22 may be restricted to move in the thickness direction Y of the seat 200 by other components, and the sliding member 4 may be restricted to move in the front-back direction. At the same time, the stability of the relative position of the first transmission member 221 and the second transmission member 222 may be ensured, thereby ensuring the stability and accuracy of the driving force transmission of the drive mechanism 21.

[0045] In some examples, refer to Figure 2 and Figure 3The guide member 3 is provided with a guide groove 31, which extends along the height direction Z of the seat 200. The end of the slider 4 furthest from the support member 1 can pass through the guide groove 31. The guide groove 31 guides the slider 4, thereby improving the stability and accuracy of the movement of the support member 1. The guide groove 31 also limits the movement range of the slider 4, ensuring that the support member 1 moves within a preset range. As an example, if the outer diameter of the end of the slider 4 furthest from the support member 1 is larger than the size of the guide groove 31, a bolt can be provided on the slider 4. The bolt and the end of the slider 4 furthest from the support member 1 are respectively located on both sides of the guide member 3 in the thickness direction Y of the seat 200, to limit the displacement of the slider 4 in the front-back direction, thereby limiting the displacement of the support member 1 in the front-back direction. In another example, by providing two bolts on the slider 4, with the two bolts respectively located on both sides of the guide member 3 in the thickness direction Y of the seat 200, the displacement of the slider 4 in the front-back direction can be limited, thereby limiting the displacement of the support member 1 in the front-back direction.

[0046] Reference Figure 2 and Figure 3 A portion of the transmission mechanism 22 can also pass through the guide groove 31. As an example, a portion of the connector 223 passes through the guide groove 31, which also guides the connector 223, thereby improving the stability and accuracy of the movement of the carrier 1. The guide groove 31 can also limit the movement range of the connector 223, thereby ensuring that the carrier 1 moves within a preset range.

[0047] In some embodiments, the guide member 3 has a first end 32 and a second end 33 opposite each other in the height direction Z of the seat 200, and the bracket assembly 5 includes a first bracket 51 and a second bracket 52. The first bracket 51 is disposed near the first end 32 of the guide member 3, and the second bracket 52 is disposed near the second end 33 of the guide member 3. The first bracket 51 and the second bracket 52 fix both ends of the guide member 3 to the seat 200, improving the installation stability of the guide member 3. The first bracket 51 and the second bracket 52 can be formed by bending or casting metal sheets, and their shape and size can be designed according to the structure of the guide member 3 and the seat 200 to ensure the reliability of the connection.

[0048] In some examples, refer to Figure 1 and Figure 2The number of guide members 3 can be two, and the two guide members 3 can be distributed at intervals in the width direction X of the seat 200. As an example, the two guide members 3 can be symmetrically arranged on both sides in the width direction X of the seat 200. In this way, the two guide members 3 can make the load on the support member 1 more even, thereby improving the stability of the movement of the support member 1 and reducing the shaking of the support member 1 during movement. Correspondingly, the number of first brackets 51 and the number of second brackets 52 are both two. The two first brackets 51 are respectively arranged near the first end 32 of the two guide members 3, and the two second brackets 52 are respectively arranged near the second end 33 of the two guide members 3.

[0049] In some embodiments, refer to Figure 1 and Figure 2 The support assembly 5 may further include a third support 53 and a fourth support 54. The two ends of the third support 53 can be connected to the two first supports 51 respectively, and the two ends of the fourth support 54 can be connected to the two second supports 52 respectively. The third support 53 and the fourth support 54 can be made of metal rods or metal plates, and can be connected to the first supports 51 and the second supports 52 respectively by bolts or welding. The third support 53 connects the two first supports 51 into a whole, and the fourth support 54 connects the two second supports 52 into a whole, further improving the overall strength and stability of the support assembly 5 and preventing the guide member 3 from deforming or displacing under stress.

[0050] In some embodiments, at least the outer surface of the guide member 3 in contact with the slider 4 may be provided with a first protective member (not shown) to reduce frictional noise generated when the guide member 3 and the slider 4 slide relative to each other. In some embodiments, at least the outer surface of the slider 4 in contact with the guide member 3 may be provided with a second protective member (not shown) to reduce frictional noise generated when the slider 4 and the guide member 3 slide relative to each other. In this embodiment, at least the outer surface of the guide member 3 in contact with the slider 4 is provided with a first protective member, and at least the outer surface of the slider 4 in contact with the guide member 3 is provided with a second protective member. As an example, the first and second protective members may be made of materials with good wear resistance and lubrication properties, such as rubber, polytetrafluoroethylene, or nylon. The first and second protective members can be fixed to the contact surfaces of the guide member 3 and the slider 4 respectively by means of pasting, embedding, or injection molding, which can effectively reduce the coefficient of friction, reduce wear, and at the same time play a role in buffering and noise reduction, thereby improving the user experience.

[0051] According to a second aspect of this application, a vehicle is provided, including a seat 200 and a seat footrest structure 100, the seat footrest structure 100 being disposed on the seat 200.
