Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0034] The following is for reference. Figure 1 and Figure 2 The seat 10 provided in the embodiments of this application is described.

[0035] Firstly, such as Figure 1 and Figure 2 As shown, this application embodiment provides a seat 10, including: a seat body 1, a table 2, a first detection element 3, and a drive mechanism 4.

[0036] Specifically, refer to Figure 1 and Figure 2 The seat body 1 includes a backrest 11 and a table 2 movably disposed on the rear side of the backrest 11 in the vertical direction; a first detection element 3 is disposed on the backrest 11 for detecting the height of the user behind the backrest 11; a drive mechanism 4 is disposed on the seat body 1 and connected to the table 2 for driving the table 2 to move, and the drive mechanism 4 is communicatively connected to the first detection element 3 and is configured to automatically drive the table 2 to move according to the detection data of the first detection element 3.

[0037] It should be noted that the tabletop 2 is located behind the backrest 11, which makes it convenient for users to place objects such as mobile phones and computers on the tabletop 2, thus meeting the user's needs.

[0038] Understandably, the first detection element 3, located on the backrest 11, detects the height of the user behind it (the height of the user behind it refers to the height of the user when seated on the back seat). This data is then transmitted to the drive mechanism 4. The drive mechanism 4 can automatically move the tabletop 2 to a suitable position based on the data detected by the first detection element 3, thus adapting to the needs of users of different heights. Of course, the drive mechanism 4 and the first detection element 3 can also communicate with a controller. That is, both the first detection element 3 and the drive mechanism 4 are connected to the controller. The controller analyzes the data transmitted from the first detection element 3 to achieve more precise control of the drive mechanism 4.

[0039] Meanwhile, the backrest 11 is also equipped with buttons or a control panel on the back to move the table 2 up and down, so that users can actively adjust the table 2 and meet different user needs.

[0040] In addition, the tabletop 2 and the drive mechanism 4 can be a single piece or detachably connected. For example, when the tabletop 2 and the drive mechanism 4 are detachably connected, the tabletop 2 can be removed from the drive mechanism 4 when it is no longer needed.

[0041] The seat 10 provided in this embodiment is movably disposed on the rear side of the backrest 11 via the table 2 in the vertical direction; the first detection element 3 is disposed on the backrest 11 for detecting the height of the user behind the backrest 11; the drive mechanism 4 is disposed on the seat body 1 and connected to the table 2 for driving the table 2 to move. The drive mechanism 4 is communicatively connected to the first detection element 3 and is configured to automatically drive the table 2 to move according to the detection data of the first detection element 3, so that the table 2 can adaptively adjust its height according to the user, thereby adapting to the needs of users of different heights.

[0042] In one possible implementation of this application, such as Figure 1 and Figure 2 As shown, the drive mechanism 4 includes a lead screw 41, a slider 42, and a drive motor 43. The lead screw 41 extends in the vertical direction. The slider 42 is sleeved on the lead screw 41 and can move along the length of the lead screw 41. The table 2 is connected to the slider 42. The drive motor 43 is located inside the backrest 11 and is used to drive the lead screw 41 to rotate.

[0043] It should be noted that the inner circumferential wall of the slider 42 has an internal thread, which is engaged with the external thread on the outer circumferential wall of the lead screw 41. Since the slider 42 is connected to the table 2, the table 2 cannot rotate relative to the backrest 11, so that the rotation of the lead screw 41 can drive the slider 42 to move in the extension direction of the lead screw 41 (moving in the vertical direction).

[0044] Understandably, when the tabletop 2 needs to rise, the drive motor 43 operates, driving the lead screw 41 to rotate in one direction (e.g., counterclockwise), thereby driving the slider 42 to move upward and causing the tabletop 2 to rise. When the tabletop 2 needs to fall, the output shaft of the drive motor 43 reverses, driving the lead screw 41 to rotate in the opposite direction (e.g., clockwise), thereby driving the slider 42 to move downward and causing the tabletop 2 to fall. Thus, the drive mechanism 4 drives the tabletop 2 to move in the vertical direction.

[0045] In addition, the drive motor 43 is located inside the backrest 11, which can prevent the drive motor 43 from being exposed to the outside, thus improving the service life of the drive motor 43. At the same time, the backrest 11 can block the noise of the drive motor 43 when it is working, reducing the noise when the table 2 is raised and lowered.

[0046] In one possible implementation of this application, such as Figure 2 As shown, the drive mechanism 4 also includes a gearbox 44, which is located inside the backrest 11. The input shaft of the gearbox 44 is connected to the output shaft of the drive motor 43, and the output shaft of the gearbox 44 is connected to the lead screw 41. It can be understood that the drive motor 43 and the lead screw 41 are connected via the gearbox 44, which reduces the output speed of the drive motor 43 and increases its output torque. This makes the lifting and lowering of the tabletop 2 more stable and reliable, preventing excessively fast lifting and lowering speeds that could cause jerking.

[0047] Furthermore, the gearbox 44 is located inside the backrest 11, which prevents the gearbox 44 from being exposed to the outside and improves the service life of the gearbox 44. At the same time, the backrest 11 can block the noise generated by the gearbox 44 when it is working and reduce the noise when the table 2 is raised and lowered.

[0048] In one possible implementation of this application, such as Figure 1 and Figure 2 As shown, the backrest 11 has a slide rail 12 extending in the vertical direction, and at least a portion of the slider 42 is movably disposed within the slide rail 12. It is understood that the movable disposal of at least a portion of the slider 42 within the slide rail 12 restricts the slider 42 within the slide rail 12, preventing the slider 42 from rotating or moving in the left, right, forward, or backward directions.

[0049] In one possible implementation of this application, such as Figure 1As shown, the tabletop 2 and the drive mechanism 4 are connected by a connecting assembly 5. The connecting assembly 5 includes two connecting rods 51 arranged vertically, with their ends facing the tabletop 2 connected to each other. The distance between the two connecting rods 51 gradually increases from the tabletop 2 to the drive mechanism 4. The tabletop 2 and the connecting assembly 5 can be detachably connected, or they can be a single piece. Similarly, the connecting assembly 5 and the drive mechanism 4 can be detachably connected, or they can be a single piece.

[0050] It is understandable that by connecting the tabletop 2 and the drive mechanism 4 (e.g., the slider 42 on the drive mechanism 4) with two connecting rods 51, the connection reliability between the tabletop 2 and the drive mechanism 4 is improved. At the same time, the ends of the two connecting rods 51 facing the tabletop 2 are connected to each other. From the tabletop 2 to the drive mechanism 4, the distance between the two connecting rods 51 gradually increases, thereby forming a triangular support between the two connecting rods 51, which improves the support for the tabletop 2 and further improves the connection reliability between the tabletop 2 and the drive mechanism 4.

[0051] In one possible implementation of this application, such as Figure 1 As shown, the connecting components 5 are multiple components spaced apart along the left-right direction. This improves the support and connection reliability of the tabletop 2, for example, in... Figure 1 In the example shown, there are two connecting components 5, but the present invention is not limited to this. There can be more connecting components 5, such as 3, 4, 5 or 6.

[0052] In one possible implementation of this application, such as Figure 1 As shown, the first detection element 3 includes an infrared detector and / or a camera, and is located on the rear side of the backrest 11. It can be understood that the infrared detector and / or camera can detect the height of the user behind the tabletop 2, thereby enabling the tabletop 2 to adaptively adjust its height according to the user.

[0053] The vehicle provided according to an embodiment of this application is described below.

[0054] Secondly, this application provides a vehicle including the aforementioned seat 10 and a rear seat, the rear seat being located behind the seat 10. It should be noted that the structure of the rear seat can be the same as that of the seat 10.

[0055] The vehicle provided in this application embodiment has a seat 10 as described above, and a table 2 that is movable in the vertical direction is located on the rear side of the backrest 11. A first detection element 3 is located on the backrest 11 and is used to detect the height of the user behind the backrest 11. A drive mechanism 4 is located on the seat body 1 and connected to the table 2, and is used to drive the table 2 to move. The drive mechanism 4 is communicatively connected to the first detection element 3 and is configured to automatically drive the table 2 to move according to the detection data of the first detection element 3, so that the table 2 can adaptively adjust its height according to the user, thereby adapting to the needs of users of different heights.

[0056] In one possible implementation of this application, the vehicle further includes a second detection element, which is disposed on the rear seat and used to detect the height of the user when seated in the rear seat. It is understood that the cooperation between the second detection element and the first detection element 3 can, on the one hand, more accurately identify the height of the user when seated in the rear seat.

[0057] On the other hand, the second detection element can detect whether the user is seated properly. When the user is seated, a movement signal can be transmitted to the drive mechanism 4 to drive the table 2 to move to the appropriate position. When the user is not seated or stands up, the signal transmitted to the drive mechanism 4 through the second detection element can control the drive mechanism 4 to drive the table 2 to the highest position, thereby avoiding interference from the table 2 when the user stands up.

[0058] In one possible implementation of this application, the second detection element includes a pressure sensor for detecting the body pressure distribution when the user sits down in the back seat. It is understood that by installing a pressure sensor on the back seat, when the user sits down, the body pressure distribution on the back seat is used to determine whether the user is seated and the user's height, thereby enabling the second detection element to detect the user's height when seated in the back seat.

[0059] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
