DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as a reference, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientations. When the product is placed in different postures, the orientation may change, for example, "upper" and "lower" may be interchangeable. Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those skilled in the art.

[0050] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0051] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the present application provides a seat, which includes a seat frame 100, a backrest body 200, a cushion body 300 and a telescopic mechanism 400. It should be noted that the backrest body 200 and the cushion body 300 can be made of soft materials, for example.

[0052] The seat frame 100 includes a backrest frame 101 and a seat cushion frame 102, and the backrest frame 101 and the seat cushion frame 102 are rotatably connected. The backrest body 200 covers at least a portion of the backrest frame 101, and the seat cushion body 300 covers at least a portion of the seat cushion frame 102. It can be understood that the backrest body 200 at least covers the side of the backrest frame 101 facing the passenger's body, and the seat cushion body 300 at least covers the side of the seat cushion frame 102 facing the passenger's body, so as to ensure that the passenger can sit comfortably on the seat cushion body 300 and lean against the backrest body 200, so as to ensure the comfort of the passenger when sitting.

[0053] The driving end of the telescopic mechanism 400 is connected to the cushion body 300 , wherein the telescopic mechanism 400 is used to drive the cushion body 300 to rotate relative to the cushion frame 102 so that the cushion body 300 is flush with the backrest body 200 in a horizontal position.

[0054] It should be noted that, since the telescopic mechanism 400 can drive the seat cushion body 300 to rotate to a position flush with the backrest body 200, when the backrest body 200 is laid flat, by adjusting the position of the seat cushion body 300, there will be no height difference between the seat cushion body 300 and the backrest body 200. Therefore, when a passenger lies on the seat, since the seat cushion body 300 is flush with the backrest body 200, the comfort of the passenger's waist can be improved. In other words, the seat provided by the embodiment of the present application can improve the comfort of the user when lying on the seat.

[0055] The following is combined with Figures 1 to 6 The details and functions of the seat provided in the embodiment of the present application are described in more detail.

[0056] Combination Figure 1 and Figure 2As shown, in some embodiments, one end of the cushion body 300 close to the backrest body 200 is connected to the driving end of the telescopic mechanism 400. It should be noted that when a passenger sits on the seat, the end of the cushion body 300 close to the backrest body 200 is generally lower than the end of the cushion body 300 away from the backrest body 200, so that an angle more suitable for the sitting posture of the human body can be formed between the cushion body 300 and the backrest body 200, so as to fit the sitting posture of the human body and make the passenger more comfortable when sitting. By connecting the driving end of the telescopic mechanism 400 to the end of the cushion body 300 close to the backrest body 200, when the backrest body 200 is laid flat, the telescopic mechanism 400 drives the end of the cushion body 300 close to the backrest body 200 to rotate relative to the end of the cushion body 300 away from the backrest body 200, so as to ensure that the cushion body 300 can be rotated to a position flush with the backrest body 200, so as to avoid the height difference between the cushion body 300 and the backrest body 200, and improve the comfort of the waist when the passenger lies down.

[0057] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the telescopic mechanism 400 includes a drive assembly 401 and a bearing plate 402. The cushion body 300 is mounted on the bearing plate 402, and the bearing plate 402 is located on the side of the cushion body 300 close to the backrest body 200. One end of the bearing plate 402 close to the backrest body 200 is connected to the driving end of the drive assembly 401, and the drive assembly 401 is used to push the bearing plate 402 to move upward. It should be noted that the bearing plate 402 can provide support for the cushion body 300 to avoid deformation of the cushion body 300. At the same time, since the contact area between the bearing plate 402 and the cushion body 300 is large, it can be avoided that when the drive assembly 401 pushes the cushion body 300, the cushion body 300 can be prevented from being partially lifted by the driving end of the drive assembly 401 and bulging, thereby improving the comfort of passengers sitting on the cushion body 300.

[0058] like Figure 5 As shown, in some embodiments, the bearing plate 402 is provided with a plurality of weight-reducing holes 404. Such a configuration can achieve a weight-reducing effect, thereby facilitating the lightweighting of the seat.

[0059] like Figure 5 As shown, in some embodiments, the side of the supporting plate 402 close to the backrest body 200 is bent upward and fits with the side of the cushion body 300 close to the backrest body 200. In this way, the supporting plate 402 can match the shape of the cushion body 300, which is more conducive to the supporting plate 402 driving the cushion body 300 to rotate.

[0060] Combination Figure 3 and Figure 4As shown, in some embodiments, the seat frame 100 further includes a first fixed bracket 103 and a second fixed bracket 104 arranged opposite to each other, and the first fixed bracket 103 and the second fixed bracket 104 extend along the length direction of the seat respectively. The cushion frame 102 includes a first support member 105 and a second support member 106 arranged opposite to each other, and the first support member 105 is slidably matched with the first fixed bracket 103, and the second support member 106 is slidably matched with the second fixed bracket 104. It can be understood that when the first support member 105 slides relative to the first fixed bracket 103 and the second support member 106 slides relative to the second fixed bracket 104, the position of the seat in the length direction can be adjusted. It should be noted that the first fixed bracket 103 and the second fixed bracket 104 can be fixedly connected to the bottom of the vehicle body respectively. In the embodiment of the present application, the length direction of the seat is parallel to the length direction of the vehicle. At the same time, the first support member 105 and the second support member 106 can support the cushion frame 102 to ensure the stability of the cushion frame 102.

[0061] Combination Figure 3 and Figure 4 As shown, in some embodiments, one of the first support member 105 and the first fixed bracket 103 is provided with a first slide groove (not shown in the figure), and the other is provided with a first slide rail (not shown in the figure), and the first slide rail is located in the first slide groove. One of the second support member 106 and the second fixed bracket 104 is provided with a second slide groove (not shown in the figure), and the other is provided with a second slide rail (not shown in the figure), and the second slide rail is located in the second slide groove, wherein the first slide groove extends along the length direction of the seat. Therefore, when the first slide rail moves in the first slide groove and the second slide rail moves in the second slide groove, the position of the seat in the length direction can be adjusted.

[0062] Combination Figure 4 and Figure 5 As shown, in some embodiments, the telescopic mechanism 400 further includes a fixing plate 403, one end of which is connected to the fixing end of the driving assembly 401, and the other end of which is fixedly connected to the first fixing bracket 103 or the vehicle body. It should be noted that the fixing plate 403 can locate the position of the driving assembly 401 and support the driving assembly 401 to ensure that the driving assembly 401 runs smoothly.

[0063] like Figure 5 and Figure 6As shown, in some embodiments, the drive assembly 401 includes a motor 407, a worm wheel (not shown in the figure), a worm (not shown in the figure), a threaded rod 405 and a housing 406, wherein the worm is connected to the output shaft of the motor and rotates synchronously with the output shaft of the motor 407. The housing 406 of the motor 407 is connected to the carrier plate 402. The outer wall of the worm wheel is meshed with the worm, and the worm wheel is sleeved on the threaded rod 405, the axial direction of the threaded rod 405 is not parallel to the axial direction of the worm, and the threaded rod 405 is threadedly matched with the inner wall of the housing 406. The housing 406 is fixedly connected to the fixing plate 403. It should be noted that when the passenger needs to lie down, the backrest can be laid flat first, and then the motor 407 can be started to rotate the worm. Thereby, the worm can drive the worm wheel to rotate, and then the threaded rod 405 can rotate synchronously with the worm wheel. Since the housing 406 is fixedly connected to the fixing plate 403, the housing 406 does not move. When the threaded rod 405 rotates, the housing 406 can provide a reverse force to the threaded rod 405, so that the threaded rod 405 is screwed out of the housing 406 to lift the bearing plate 402, thereby driving the seat cushion body 300 to rotate relative to the seat cushion frame 102, so that the seat cushion body 300 can be kept flush with the flat backrest body 200. It should be understood that when the passenger needs to sit up, the motor 407 can be rotated in the reverse direction, so that the threaded rod 405 can be gradually screwed into the housing 406, thereby driving the bearing plate 402 to rotate in the reverse direction, so that the seat cushion body 300 can be restored to its original position.

[0064] In some embodiments, the seat further comprises a moving mechanism 500, the driving end of the moving mechanism 500 is connected to the seat cushion frame 102, and the moving mechanism 500 is used to drive the seat cushion frame 102 to move along the extension direction of the first fixing bracket 103. Thus, the position of the seat in the length direction can be adjusted. For example, before laying down the backrest body 200, the moving mechanism 500 can be used to adjust the distance between the front row seat and the rear row seat, so as to ensure that the backrest body 200 of the front row seat can be laid down smoothly.

[0065] In some embodiments, the driving end of the moving mechanism 500 is connected to the first support member 105 and / or the second support member 106, and the fixed end of the moving mechanism 500 can be installed on the first fixed bracket 103, the second fixed bracket 104 or the vehicle body. The moving mechanism 500 is used to push the first support member 105 and the second support member 106 to slide relative to the first fixed bracket 103 and the second fixed bracket 104, respectively, to adjust the position of the seat in the length direction.

[0066] Combination Fig. 9As shown, in some embodiments, the seat further includes a headrest 800, a headrest position detector 700 and a controller 600, and the headrest 800 is detachably connected to the backrest body 200. The controller 600 is electrically connected to the headrest position detector 700, and the controller 600 is electrically connected to the drive assembly 401 and the moving mechanism 500. It should be noted that the headrest position detector 700 can be, for example, a sensor such as a position sensor. It should be understood that the controller 600 can be electrically connected to the motor of the drive assembly 401. The headrest position detector 700 is used to detect the position of the headrest 800 and send the position of the headrest 800 to the controller 600. The controller 600 is used to control the moving mechanism 500 to push the seat to move to a preset position when the headrest 800 has been disassembled from the backrest body 200, and control the drive assembly 401 to drive the seat cushion to rotate to a position flush with the backrest body 200. It should be noted that after the headrest 800 is separated from the backrest body 200, the backrest body 200 can be rotated to a flat position by the passenger manually controlling a rotation button of the backrest body 200 or by using a driving motor that controls the backrest body 200 or the backrest frame 101. It should be noted that the backrest frame 101 and the backrest body 200 rotate synchronously.

[0067] From the above, it can be seen that the seat provided in the embodiment of the present application can rotate the seat cushion body 300 to a position flush with the flat backrest body 200 when the passenger needs to lie down, thereby ensuring that there is no height difference between the seat cushion body 300 and the backrest body 200, thereby improving the comfort of the passenger when lying down.

[0068] Second, as Figure 7 As shown, the embodiment of the present application further provides a seat control method, which can be executed by a controller 600 on a vehicle. The seat control method is used to control the seat in any one of the embodiments of the present application in the first aspect, and the seat control method includes steps 101 to 102.

[0069] In step 101 , the controller 600 generates a lay-flat instruction in response to a first trigger operation.

[0070] It should be noted that the seat has a lay-flat mode and a sit-up mode, and the first trigger operation refers to the operation of the user selecting the lay-flat mode. For example, a lay-flat button and a sit-up button corresponding to the lay-flat mode and the sit-up mode are displayed on a display screen in the vehicle electrically connected to the controller 600, respectively. The first trigger operation may be, for example, the user clicking or double-clicking the lay-flat button.

[0071] In step 102 , the controller 600 rotates the backrest frame 101 by a preset angle based on the flattening instruction to make the backrest body 200 in a horizontal position, and controls the telescopic mechanism 400 to drive the seat cushion body 300 to rotate to a position flush with the backrest body 200 .

[0072] It should be noted that the flush position of the seat cushion body 300 and the backrest body 200 in the embodiment of the present application means that when the backrest body 200 is in a roughly horizontal position, the upper surface of the seat cushion body 300 and the upper surface of the backrest body 200 are both horizontal and flush with each other.

[0073] With such arrangement, when the user needs to lie down, the seat back body 200 and the seat cushion body 300 can be automatically adjusted to a flush position with each other, avoiding a height difference between the seat cushion body 300 and the back body 200, thereby improving the comfort of the passenger when lying down.

[0074] like Figure 8 As shown, the embodiment of the present application further provides a seat control method, which can be executed by a controller 600 on a vehicle. The seat control method is used to control the seat in any one of the embodiments of the present application in the first aspect, and the seat control method includes steps 201 to 202.

[0075] In step 201 , the controller 600 obtains the disassembly status of the headrest 800 in response to a first trigger operation.

[0076] In some embodiments, the controller 600 sends an acquisition instruction to the headrest position detector 700 in response to the first trigger operation. The headrest position detector 700 sends the detected position of the headrest 800 to the controller 600.

[0077] In step 202 , the controller 600 generates a first movement instruction in response to the headrest 800 being in a disassembled state.

[0078] It should be noted that the headrest 800 being in the disassembled state means that the headrest 800 has been separated from the backrest body 200 and is not in a position connected to the backrest body 200 .

[0079] In step 203 , the controller 600 moves the seat frame 100 to a preset position based on the first movement instruction, and generates a lay-flat instruction.

[0080] It should be noted that steps 201 to 203 are one implementation of the controller 600 generating a lay-flat instruction in response to the first trigger operation in step 102. Since the seat frame 100 is moved and the lay-flat instruction is generated after confirming that the headrest 800 has been removed, it can ensure that the front seat and the rear seat are kept at a preset distance before the body is laid flat, so as to ensure that the backrest body 200 can be laid flat smoothly and avoid the backrest body 200 from colliding with other components during the laying process and being damaged.

[0081] In step 204 , the controller 600 rotates the backrest frame 101 by a preset angle based on the flattening instruction to make the backrest body 200 in a horizontal position, and controls the telescopic mechanism 400 to drive the seat cushion body 300 to rotate to a position flush with the backrest body 200 .

[0082] It should be noted that step 204 is the same as step 102, so this application will not repeat them here.

[0083] With such a configuration, when a passenger needs to lie down, the seat position and the posture of the seat back body 200 and the seat cushion body 300 can be automatically adjusted, thereby ensuring that the seat cushion body 300 can be flush with the back body 200, avoiding a height difference between the seat cushion body 300 and the back body 200, and thus making the waist of the passenger more comfortable when lying down. In other words, the seat control method provided in the embodiment of the present application can automatically adjust the seat position and posture when a passenger needs to lie down, which not only simplifies the user operation, but also improves the user comfort.

[0084] In the third aspect, the embodiment of the present application further provides a vehicle, the vehicle comprising the seat described in any one of the embodiments of the present application in the first aspect. It should be noted that the composition and function of the seat in the vehicle provided in the embodiment of the present application are the same as the composition and function of the seat described in any one of the embodiments of the present application in the first aspect, so the embodiments of the present application will not be repeated here. Since the seat can adjust the seat cushion body 300 to a position flush with the flat backrest body 200 when the passenger lies down, the comfort of the passenger can be improved, thereby improving the comfort of the vehicle and the user's experience of using the vehicle.

[0085] Those skilled in the art will readily appreciate other embodiments of the present application after considering the specification and practicing the present application disclosed herein. The present application is intended to cover any variations, uses or adaptations of the present application, which follow the general principles of the present application and include common knowledge or customary techniques in the art that are not disclosed in the present application.
