Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to seats and vehicles. Background Technology

[0002] Vehicle seats are typically located within the vehicle's interior space, and the interior space is utilized efficiently. The seat backs are usually foldable so that when no passengers are sitting in the seat, the backs can be reclined to reduce the space occupied by the seat, thus making better use of the vehicle's interior space.

[0003] In the prior art, the seat includes a seat cushion frame and a backrest frame. The seat cushion frame is connected to a hidden groove via a foot bracket. The backrest frame is rotatably connected to the upper rear end of the seat cushion frame via two adapter plates. One end of the adapter plate is connected to the backrest frame via an adjuster and a rotating shaft, and the other end of the adapter plate is connected to both ends of the seat cushion frame.

[0004] However, adjusting the backrest frame of the aforementioned seats is rather cumbersome, and the space freed up after adjustment is limited, resulting in a poor user experience. Utility Model Content

[0005] This application provides a seat and a vehicle to at least solve the technical problem of how to conveniently adjust the seat back and free up more space. The technical solution adopted in this application is as follows:

[0006] According to a first aspect of this application, a seat is provided. The seat includes a support component, a backrest, a drive component, and a transmission component. The support component includes a base and a seat cushion. The seat cushion is connected to the base and is capable of rising and falling relative to the base. The backrest is rotatably connected to the base to switch between a folded state and a sitting state. The drive component is transmissionally connected to the backrest for driving the backrest to rotate. The transmission component is connected between the support component and the backrest. During the switching process from a sitting state to a folded state, the backrest rotates towards the seat cushion and drives the seat cushion to fall through the transmission component. During the switching process from a folded state to a sitting state, the backrest rotates away from the seat cushion and drives the seat cushion to rise through the transmission component.

[0007] Based on the aforementioned technical means, when it is necessary to free up space above the seat, the drive mechanism can be activated to rotate the backrest, thereby switching the backrest from a seated position to a folded position. During this process, the transmission component can lower the seat cushion, so that after the backrest is folded up to the top of the seat cushion, the overall height of the backrest and seat cushion is lower, thus freeing up more space above the seat for more efficient use of the vehicle's interior space. Furthermore, switching between the folded and seated positions only requires starting and stopping the drive mechanism, making backrest adjustment more convenient and quick.

[0008] In one possible implementation, the seat further includes an adjustment assembly connected between the backrest and the base, and a drive member is kinetically connected to the adjustment assembly to drive the backrest to rotate via the adjustment assembly.

[0009] According to the above-mentioned technical means, by connecting the backrest and the seat cushion through the adjustment component, and driving the adjustment component through the drive component, the backrest can be rotated through the adjustment component, which can make the backrest more stable when rotating relative to the base, so as to ensure the stability of the backrest during adjustment.

[0010] In one possible implementation, the adjustment assembly includes a first synchronizing rod, a first angle adjuster, and a second angle adjuster. Along the width direction of the seat, the first angle adjuster is located on one side of the base, and the second angle adjuster is located on the other side of the base. Both the first and second angle adjusters are connected between the base and the backrest. The first synchronizing rod is connected between the first and second angle adjusters, and a driving member is kinetically connected to the first synchronizing rod to drive the first synchronizing rod to rotate.

[0011] According to the above-mentioned technical means, the first and second angle adjusters can rotate synchronously to improve the smoothness and stability of the backrest rotation. Furthermore, during the backrest rotation process, the first and second angle adjusters can support the backrest from both sides to improve the stability of the backrest support, thereby further improving the stability of the backrest rotation.

[0012] In one possible implementation, the driving element is a Hall effect dual-speed motor.

[0013] Based on the aforementioned technical means, by setting up a Hall dual-speed motor, the operating speed of the drive components can be adjusted according to actual needs to meet the different adjustment needs of drivers and passengers for the backrest, thus facilitating the adjustment of the backrest by drivers and passengers.

[0014] In one possible implementation, the seating state includes a first seating state and a second seating state. When the backrest is in the first seating state, the angle between the backrest and the seat cushion is a first angle, and when the backrest is in the second seating state, the angle between the backrest and the seat cushion is a second angle. The first angle is smaller than the second angle. The seat also includes a first adjustment button, which is movably connected to the seat cushion and electrically connected to a drive component, for causing the drive component to switch the backrest between the first seating state and the second seating state.

[0015] According to the above-mentioned technical means, by setting a first adjustment button on the seat cushion, the driver and passengers can control the operation of the drive component by adjusting the first adjustment button when sitting on the seat, thereby adjusting the backrest to the first or second sitting state, so as to facilitate the driver and passengers to adjust the backrest.

[0016] In one possible implementation, the seat also includes a first sensor located on the seat cushion for detecting whether there is a person in the seat, so as to avoid switching the backrest to a folded state when there is a person in the seat.

[0017] Based on the above-mentioned technical means, the backrest can be switched to a folding state when there are people in the seat, thereby avoiding injury to the driver and passengers and improving their safety and riding experience.

[0018] In one possible implementation, the seat also includes a second sensor located on the backrest for detecting whether there is an item on the backrest when the backrest is in a folded state, so as to prevent the backrest from switching to a sitting state when there is an item on the backrest.

[0019] The above-mentioned technical means can prevent the backrest from switching to a sitting position when there are items on it, thereby preventing items on the backrest from slipping off and causing damage.

[0020] In one possible implementation, the transmission assembly includes a first transmission member and a second transmission member, one end of the first transmission member being rotatably connected to the backrest and the other end of the first transmission member being connected to the seat cushion; one end of the second transmission member being rotatably connected to the seat cushion and the other end of the second transmission member being rotatably connected to the base.

[0021] According to the above-mentioned technical means, through the cooperation of the first transmission component and the second transmission component, the seat cushion can be raised and lowered simultaneously when the drive component drives the backrest to switch between the folded state and the sitting state. During the seat adjustment process, the driver and passenger do not need to adjust the backrest and seat cushion separately, which improves the convenience of adjustment.

[0022] In one possible implementation, the second transmission component includes a second synchronizing rod, a first connecting rod, and a second connecting rod. The first connecting rod and the second connecting rod are spaced apart along the width direction of the seat. One end of the first connecting rod and one end of the second connecting rod are rotatably connected to the front end of the seat cushion, and the other end of the first connecting rod and the other end of the second connecting rod are rotatably connected to the base. The second synchronizing rod is connected between the first connecting rod and the second connecting rod.

[0023] Based on the aforementioned technical means, the arrangement of the first and second links makes the seat cushion's lifting and lowering more stable. Furthermore, by connecting the first and second links with a second synchronizing rod, the synchronicity of their movements during seat cushion lifting and lowering is ensured, thus guaranteeing smoother seat cushion lifting and lowering.

[0024] According to a second aspect provided in this application, a vehicle is provided, including the aforementioned seat, body, and second adjustment button. The seat is located inside the body; the second adjustment button is connected to the outside of the body and electrically connected to a drive component, for causing the drive component to drive the backrest to switch between a folded state and a seated state.

[0025] In one possible implementation, the seating state includes a first seating state and a second seating state. When the backrest is in the first seating state, the angle between the backrest and the seat cushion is a first angle, and when the backrest is in the second seating state, the angle between the backrest and the seat cushion is a second angle. The first angle is smaller than the second angle. The vehicle also includes a controller electrically connected to a drive unit. The controller is used to control the rotational speed of the drive unit so that the rotational speed of the backrest when switching between the first seating state and the second seating state is less than the rotational speed of the backrest when switching between the seating state and the folded state.

[0026] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0027] (1) When it is necessary to free up space above the seat, this application can activate the drive mechanism to rotate the backrest, thereby switching the backrest from a seated state to a folded state. During this process, the transmission component can drive the seat cushion to descend, so that after the backrest is folded over the seat cushion, the overall height of the backrest and seat cushion is lower, thereby freeing up more space above the seat for more efficient use of the vehicle's interior space. Furthermore, the backrest can be switched between the folded and seated states simply by activating and stopping the drive mechanism, making backrest adjustment more convenient and faster.

[0028] (2) This application connects the backrest and the seat cushion through the adjustment component and drives the adjustment component through the drive component, thereby driving the backrest to rotate through the adjustment component, which can make the backrest more stable when rotating relative to the base, so as to ensure the stability of the backrest during adjustment.

[0029] (3) The first adjustment device and the second adjustment device can rotate synchronously through the first synchronization rod to improve the smoothness and stability of the backrest rotation. In addition, during the backrest rotation, the first adjustment device and the second adjustment device can support the backrest from both sides to improve the stability of the backrest support, thereby further improving the stability of the backrest rotation.

[0030] (4) This application uses a Hall dual-speed motor to adjust the running speed of the drive components according to actual needs, so as to meet the different adjustment needs of the driver and passengers for the backrest and facilitate the adjustment of the backrest by the driver and passengers.

[0031] (5) This application provides a first adjustment button on the seat cushion. When the driver or passenger is sitting in the seat, they can adjust the first adjustment button to control the operation of the drive unit, thereby adjusting the backrest to the first or second sitting state, so as to facilitate the driver or passenger to adjust the backrest.

[0032] (6) This application can prevent the backrest from switching to a folding state when there are people in the seat through the first sensor, thereby avoiding harm to the driver and passengers and improving the safety and riding experience of the driver and passengers.

[0033] (7) This application can prevent the backrest from switching to a sitting state when there are items on the backrest by using a second sensor, thereby preventing items on the backrest from slipping off and causing damage.

[0034] (8) Through the cooperation of the first transmission component and the second transmission component, this application can simultaneously drive the seat cushion to rise and fall when the drive component drives the backrest to switch between the folded state and the sitting state. During the seat adjustment process, the driver and passenger do not need to adjust the backrest and seat cushion separately, which improves the convenience of adjustment.

[0035] (9) By setting up the first link and the second link, this application can make the lifting and lowering of the seat cushion more stable. Furthermore, by connecting the first link and the second link with the second synchronizing rod, the synchronicity of the actions of the first link and the second link can be ensured during the lifting and lowering of the seat cushion, thereby ensuring smoother lifting and lowering of the seat cushion.

[0036] It should be noted that the technical effects of the second implementation method can be found in the technical effects of the corresponding implementation method in the first aspect, and will not be repeated here.

[0057] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0058] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] The first aspect of this application provides a vehicle. The vehicle can be a gasoline-powered vehicle, a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, etc.

[0060] The vehicle consists of a body and seats. The body has storage space for accommodating passengers and storing items. Seats are located within this storage space for passenger comfort. These seats can be either front or rear seats.

[0061] In some embodiments, please refer to Figure 1 The seat 10 may include a support assembly 1, a backrest 2, a drive component 3, and a transmission assembly 4. The support assembly 1 may include a base 11 and a seat cushion 12. The base 11 is used to connect to the vehicle body, and the seat cushion 12 is connected to the base 11 to support the seat cushion 12 through the base 11. The seat cushion 12 is used to support the driver and passengers.

[0062] The backrest 2 is connected to the base 11 to support the backrest 2. After the driver or passenger sits on the seat 10, the backrest 2 can support the back of the driver or passenger to improve the comfort of the driver or passenger when sitting on the seat 10.

[0063] The backrest 2 is rotatably connected to the base 11, allowing the backrest 2 to switch between a folded state and a seated state relative to the base 11. This allows for convenient seating of passengers in the seat 10 when the backrest 2 is in the seated state, and avoids the backrest 2 occupying the space above the seat 10 when the backrest 2 is folded, thus allowing for convenient placement of items in the space above the seat 10 and making better use of the vehicle's interior space.

[0064] In some examples, the backrest 2 has a first end 21 and a second end 22 arranged opposite to each other, with the first end 21 rotatably connected to the rear end of the base 11 in the length direction of the vehicle. (See also...) Figure 1When the backrest 2 is in the sitting position, the second end 22 of the backrest 2 is located above the first end 21, or the second end 22 is located above the first end 21 and behind the first end 21, that is, the angle between the surface of the backrest 2 in the thickness direction and the surface of the seat cushion 12 in the thickness direction is greater than or equal to 90°. Please refer to [link / reference]. Figure 2 and Figure 3 When the backrest 2 is in the folded state, the second end 22 of the backrest 2 is located in front of the first end 21, that is, the backrest 2 is folded on top of the seat cushion 12. This can prevent the backrest 2 from occupying the space behind the seat 10 and can free up the space above the seat 10, so as to make reasonable use of the interior space.

[0065] Please continue reading. Figure 1 The drive component 3 is connected to the backrest 2 via a transmission mechanism, and is used to drive the backrest 2 to rotate, thereby driving the backrest 2 to switch between the sitting position and the folding device. Compared with manually switching the state of the backrest 2, driving the backrest 2 to switch between the sitting position and the folding device via the drive component 3 is more convenient and faster, thus improving the experience of drivers and passengers.

[0066] The seat cushion 12 can be raised and lowered relative to the base 11. The transmission assembly 4 is connected between the support assembly 1 and the backrest 2; during the process of switching the backrest 2 from the sitting position to the folded position, the backrest 2 rotates towards the seat cushion 12, and the seat cushion 12 is lowered through the transmission assembly 4. In this way, after the backrest 2 is switched to the folded position, the seat cushion 12 can be lowered through the transmission assembly 4, thereby reducing the overall height of the backrest 2 and the seat cushion 12, thus freeing up more space above the seat 10 for more efficient use of the interior space.

[0067] During the transition from a folded state to a seated state, the backrest 2 rotates away from the seat cushion 12, and the seat cushion 12 rises via the transmission assembly 4. This allows the seat cushion 12 to rise when the backrest 2 is in the seated state, ensuring a comfortable seating height for passengers and improving leg comfort.

[0068] With the above configuration, when space above seat 10 needs to be freed up, drive component 3 can be activated to rotate backrest 2, thus switching backrest 2 from a seated position to a folded position. During this process, transmission component 4 can lower seat cushion 12, so that after backrest 2 is folded over seat cushion 12, the overall height of backrest 2 and seat cushion 12 is lower, freeing up more space above seat 10 for more efficient use of vehicle interior space. Furthermore, switching backrest 2 between folded and seated positions only requires starting and stopping drive component 3, making backrest 2 adjustment more convenient and faster.

[0069] In some embodiments, please continue reading Figure 1 and Figure 2 The seat 10 also includes an adjustment assembly 5, which is connected between the backrest 2 and the base 11, and is used to adjust the rotation angle of the backrest 2. The drive unit 3 is connected to the adjustment assembly 5 to drive the backrest 2 to rotate via the adjustment assembly 5.

[0070] In this way, by connecting the backrest 2 and the seat cushion 12 through the adjustment component 5 and driving the adjustment component 5 through the drive component 3, the backrest 2 can be rotated through the adjustment component 5, which can make the backrest 2 more stable when rotating relative to the base 11, so as to ensure the stability of the backrest 2 during adjustment.

[0071] In some embodiments, please continue reading Figure 1 The adjustment assembly 5 may include a first adjuster 51, a second adjuster 52, and a first synchronizer 53. Along the width direction of the seat 10 (i.e., the width direction of the vehicle, such as...) Figure 1 In the direction X), a first angle adjuster 51 is located on one side of the base 11, and a second angle adjuster 52 is located on the other side of the base 11. Both the first angle adjuster 51 and the second angle adjuster 52 are connected between the base 11 and the backrest 2. Both the first angle adjuster 51 and the second angle adjuster 52 are used to adjust the rotation angle of the backrest 2. For example, the first angle adjuster 51 and the second angle adjuster 52 can be continuous angle adjusters, electric angle adjusters, etc.

[0072] The first synchronizing rod 53 is connected between the first adjuster 51 and the second adjuster 52. The first synchronizing rod 53 is used to ensure that the first adjuster 51 and the second adjuster 52 rotate synchronously, so as to improve the smoothness of the backrest 2 rotation. The driving member 3 is connected to the first synchronizing rod 53 to drive the first synchronizing rod 53 to rotate.

[0073] In some examples, the output shaft of the drive unit 3 is equipped with a first gear, and the synchronizing rod is equipped with a second gear. The first gear and the second gear mesh, so that the drive unit 3 can transmit power to the first synchronizing rod 53 through the first gear and the second gear, thereby driving the first synchronizing rod 53 to rotate. The transmission method of the first gear and the second gear is relatively stable, which allows the drive unit 3 to reliably transmit power to the first synchronizing rod 53, thereby driving the first synchronizing rod 53 to rotate stably.

[0074] In other examples, the output shaft of the drive unit 3 can be directly connected to the first synchronizing rod 53, or it can be connected to the first synchronizing rod 53 through other transmission methods, such as through a synchronous belt and pulley structure, a sprocket and chain structure, etc. This application does not make specific limitations in this regard.

[0075] By driving the first synchronizing rod 53 to rotate via the driving component 3, the first synchronizing rod 53 can simultaneously drive the first adjusting device 51 and the second adjusting device 52 to rotate, thereby driving the backrest 2 to rotate. In this way, the first adjusting device 51 and the second adjusting device 52 can rotate synchronously, thereby improving the smoothness and stability of the backrest 2 during rotation. Furthermore, during the rotation of the backrest 2, the first adjusting device 51 and the second adjusting device 52 can support the backrest 2 from both sides, improving the stability of the support for the backrest 2, and further enhancing the stability of the backrest 2 during rotation.

[0076] For example, please refer to Figure 1 and Figure 4 The first angle adjuster 51 may include a fixed toothed plate 511, a toothed ring 512, and a gear 513. The fixed toothed plate 511 is fixedly connected to the base 11. The toothed ring 512 is rotatably connected to the fixed toothed plate 511 and connected to the backrest 2. Rotation of the toothed ring 512 can drive the backrest 2 to rotate, thereby adjusting the rotation angle of the backrest 2. The gear 513 is rotatably connected to the fixed toothed plate 511 and connected to the first synchronizing rod 53. Rotation of the first synchronizing rod 53 can drive the gear 513 to rotate.

[0077] The rotation axis of gear 513 is parallel to the rotation axis of gear ring 512, meaning gear 513 is eccentrically positioned relative to gear ring 512. Some teeth of gear 513 mesh with some teeth of gear ring 512. For example, the distance between the rotation axis of gear 513 and the rotation axis of gear ring 512 is small, such as 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc., to ensure that some teeth of gear 513 always mesh with some teeth of gear ring 512.

[0078] In other words, during the rotation of gear 513 driven by the first synchronizing rod 53, a portion of the teeth of gear 513 always meshes with a portion of the teeth of gear ring 512, thereby driving gear ring 512 to rotate and thus driving backrest 2 to rotate. By having a portion of the teeth of gear 513 mesh with a portion of the teeth of gear ring 512, the resistance between gear 513 and gear ring 512 can be reduced during the rotation of gear ring 512 driven by gear 513, thus making the rotation of backrest 2 easier.

[0079] As another example, gear 513 and gear ring 512 can also be coaxially arranged, that is, all teeth of gear 513 mesh with gear ring 512. In this way, the rotation of the first synchronizing rod 53 can also drive gear 513 to rotate, thereby driving gear ring 512 to rotate, and thus driving backrest 2 to rotate.

[0080] The structure of the second angle adjuster 52 can be the same as that of the first angle adjuster 51 in any of the above embodiments, and will not be described in detail here.

[0081] In other embodiments, the adjustment component 5 may also be other structures capable of rotating the backrest 2 relative to the base 11, such as a linkage mechanism, etc., which are not specifically limited in this application.

[0082] In some embodiments, please refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 The transmission assembly 4 includes a first transmission member 41 and a second transmission member 42. One end of the first transmission member 41 is rotatably connected to the backrest 2. For example, the connection position of one end of the first transmission member 41 on the backrest 2 is located between the first adjuster 51 and the second end 22 of the backrest 2. The other end of the first transmission member 41 is connected to the seat cushion 12. For example, the other end of the first transmission member 41 can be connected to the middle position of the seat cushion 12 in the length direction of the vehicle. The connection method can be welding, screwing, etc. One end of the second transmission member 42 is rotatably connected to the seat cushion 12, and the other end of the second transmission member 42 is rotatably connected to the base 11.

[0083] The first transmission member 41 is parallel to the rotation axis of the backrest 2, the second transmission member 42 is parallel to the rotation axis of the seat cushion 12, and the second transmission member 42 is parallel to the rotation axis of the base 11, for example, both extending along the width direction of the vehicle.

[0084] In this way, when the backrest 2 switches from the sitting state to the folding state, the rotation of the backrest 2 can drive one end of the first transmission member 41 connected to the backrest 2 to rotate, and will generate a downward thrust on the seat cushion 12 through the first transmission member 41 (that is, the thrust has forward and downward components). At this time, since one end of the second transmission member 42 is rotatably connected to the seat cushion 12 and the other end of the second transmission member 42 is rotatably connected to the base 11, the seat cushion 12 will push the second transmission member 42 after being pushed, so that the end of the second transmission member 42 connected to the seat cushion 12 swings forward, thereby moving the seat cushion 12 forward and downward at the same time, that is, realizing the lowering of the seat cushion 12 relative to the base 11.

[0085] When the backrest 2 switches from the folded state to the sitting state, the rotation of the backrest 2 can drive the end of the first transmission component 41 connected to the backrest 2 to rotate, and will generate an upward pulling force on the seat cushion 12 through the first transmission component 41 (that is, the pulling force has a backward component and an upward component). At this time, under the action of the pulling force, the seat cushion 12 will drive the end of the second transmission component 42 connected to the seat cushion 12 to swing backward, so that the seat cushion 12 moves backward and upward at the same time, that is, the seat cushion 12 rises relative to the base 11.

[0086] With the cooperation of the first transmission component 41 and the second transmission component 42, the seat cushion 12 can be raised and lowered simultaneously when the drive component 3 drives the backrest 2 to switch between the folded state and the sitting state. During the adjustment of the seat 10, the driver and passenger do not need to adjust the backrest 2 and the seat cushion 12 separately, which improves the convenience of adjustment.

[0087] It should be noted that the terms "front," "rear," "up," and "down" mentioned in this application are all relative to the vehicle. For example, "front side" refers to the front side along the length of the vehicle, and "rear side" refers to the rear side along the length of the vehicle. "Up" means upward along the height of the vehicle, and "down" means downward along the height of the vehicle.

[0088] In some examples, the first transmission member 41 can be a rod-shaped structure, a plate-shaped structure, an L-shaped structure, etc., and this application does not make specific limitations on it.

[0089] In some examples, the number of first transmission components 41 can be one or more. For example, there can be two first transmission components 41, located on both sides of the seat 10 in the width direction. This makes the backrest 2 more stable when it drives the seat cushion 12 to rise and fall.

[0090] In some embodiments, please continue reading Figure 1 The second transmission component 42 may include a first connecting rod 421, a second connecting rod 422, and a second synchronizing rod 423. The first connecting rod 421 and the second connecting rod 422 are spaced apart along the width direction of the seat 10. One end of the first connecting rod 421 and one end of the second connecting rod 422 are rotatably connected to the front end of the seat cushion 12, and the other end of the first connecting rod 421 and the other end of the second connecting rod 422 are rotatably connected to the base 11. The second synchronizing rod 423 connects the first connecting rod 421 and the second connecting rod 422.

[0091] In this way, the first link 421 and the second link 422 can provide support at two points on the seat cushion 12 during its lifting and lowering process, thus making the lifting and lowering of the seat cushion 12 more stable. Furthermore, by connecting the first link 421 and the second link 422 with the second synchronizing rod 423, the synchronicity of the actions of the first link 421 and the second link 422 during the lifting and lowering process of the seat cushion 12 can be ensured, thereby ensuring a smoother lifting and lowering of the seat cushion 12.

[0092] In some other embodiments, the second transmission member 42 may include only the first link 421 or only the second link 422, which can also achieve the lifting and lowering of the seat cushion 12 relative to the base 11.

[0093] In some embodiments, the drive element 3 can be a Hall dual-speed motor. The Hall dual-speed motor has a built-in Hall sensor and two different operating speeds. Thus, the rotational speed and direction of the drive element 3 can be detected by the Hall sensor, and the operating speed of the drive element 3 can be adjusted according to the rotational speed of the drive element 3 and actual needs to meet the different adjustment requirements of the driver and passengers for the backrest 2, facilitating the adjustment of the backrest 2.

[0094] In other embodiments, the drive element 3 may also be other drive devices capable of adjusting the operating speed, such as a variable frequency speed control motor, a servo motor, etc. This application does not specifically limit it in this regard.

[0095] This application uses a Hall dual-speed motor as an example to illustrate the use of drive component 3.

[0096] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 8 and Figure 9 The seating states include a first seating state and a second seating state. When the backrest 2 is in the first seating state, the angle between the backrest 2 and the seat cushion 12 is the first angle (e.g., ...). Figure 6 The included angle α shown in the figure, when the backrest 2 is in the second sitting position, the included angle between the backrest 2 and the seat cushion 12 is the second included angle (as shown in the figure). Figure 9 The included angle β shown in the figure is smaller than the second included angle.

[0097] In this way, when the driver or passenger needs to concentrate on something, such as when the driver is driving, the backrest 2 can be adjusted to the first seating position, which allows the driver or passenger to sit upright, making it easier to handle tasks and providing a more comfortable ride. For example, when the driver or passenger is in a more relaxed state, such as when resting, the backrest 2 can be adjusted to the second seating position, allowing the driver or passenger to be in a semi-reclined position, so that the driver or passenger can better relax their body.

[0098] The driver and passengers can adjust the backrest 2 to either the first or second seating position as needed, so that they can adjust the backrest 2 to a suitable seating position as needed, thus making the driver and passengers more comfortable when riding.

[0099] In some embodiments, please continue reading Figure 5When the backrest 2 is in the first seating position, both the first link 421 and the second link 422 are tilted. Specifically, the upper end of the first link 421 is closer to the front of the vehicle than the lower end, and the upper end of the second link 422 is also closer to the front of the vehicle than the lower end. In this way, during the transition from the first seating position to the second seating position, the backrest 2 can still exert a pulling force on the seat cushion 12 through the first transmission component 41, causing the seat cushion 12 to swing backward, thus raising the front end of the seat cushion 12 and creating a tilted position with a higher front and lower back. Therefore, when the driver or passenger is sitting on the seat 10 and lying on the backrest 2, they will not slide down the seat cushion 12, further improving the comfort of the driver or passenger in the seat 10.

[0100] The backrest 2 is switched between the first and second seating states by rotating it via the drive unit 3. Since the driver and passenger are adjusting the seat while seated on the seat 10, the drive unit 3 (Hall dual-speed motor) can operate at a low speed, thus preventing the backrest 2 from rotating too quickly and causing discomfort to the driver and passenger.

[0101] When the backrest 2 switches between a folded state and a seated state, the drive unit 3 can operate at high speed to facilitate rapid state switching and improve switching efficiency. Specifically, the switching between the folded and seated states of the backrest 2 can be a switch between a folded state and a first seated state.

[0102] It should be noted that the high speed mentioned above refers to the higher of the two operating speeds in the Hall dual-speed motor, while the low speed refers to the lower of the two operating speeds in the Hall dual-speed motor.

[0103] In some embodiments, please continue reading Figure 8 The seat 10 also includes a first adjustment button 6, which is movably connected to the seat cushion 12 and electrically connected to the drive unit 3, for using the drive unit 3 to drive the backrest 2 to switch between a first seating state and a second seating state.

[0104] By setting a first adjustment button 6 on the seat cushion 12, when the driver or passenger is sitting on the seat 10, they can control the operation of the drive component 3 by adjusting the first adjustment button 6, thereby adjusting the backrest 2 to the first or second seating state, so as to facilitate the driver or passenger to adjust the backrest 2.

[0105] For example, the first adjustment button 6 can be rotatably connected to the seat cushion 12, or it can be movably connected to the seat cushion 12 along the height or length direction of the vehicle, or it can be a push-button adjustment button. This application uses the first adjustment button 6 as a push-button adjustment button as an example for illustration.

[0106] In some embodiments, the vehicle further includes a controller electrically connected to the drive unit 3, the controller being used to control the rotational speed of the drive unit 3 so that the rotational speed of the backrest 2 when switching between a first seating state and a second seating state is less than the rotational speed of the backrest 2 when switching between a seating state and a folded state.

[0107] In other words, when the backrest 2 switches between the first and second seating states, the controller controls the drive unit 3 to run at a low speed. When the backrest 2 switches between the seating state and the folded state, the controller controls the drive unit 3 to run at a high speed. This makes it easier to control the rotation speed of the backrest 2.

[0108] In some examples, the controller can be an in-vehicle multimedia system module (VIU), which can control the drive unit 3 to work through the first adjustment button 6, or send instructions to control the drive unit 3 to the controller from the screen of the in-vehicle multimedia system, so as to make it easier to adjust the backrest 2.

[0109] In other examples, the controller may also be a control module separately located on seat 10, etc.

[0110] In some examples, the first adjustment button 6 can be electrically connected to the controller, that is, the first adjustment button 6 is electrically connected to the drive unit 3 through the controller. When the first adjustment button 6 is pressed, the controller is output a command to control the drive unit 3 to run at a low speed to adjust the backrest 2 between a first seating state and a second seating state. The controller can obtain the current state of the backrest 2 and then switch to the other state. That is, when the backrest 2 is in the first seating state, the drive unit 3 rotates forward at a low speed to drive the backrest 2 from the first seating state to the second seating state. When the backrest 2 is in the second seating state, the drive unit 3 rotates in reverse at a low speed to drive the backrest 2 from the second seating state to the first seating state.

[0111] In some other examples, the first adjustment button 6 can also be electrically connected to the drive unit 3 via a control circuit. In this case, the first adjustment button 6 can be rotatably connected to the seat cushion 12. When the first adjustment button 6 is rotated in a first direction, the control circuit activated can cause the drive unit 3 to rotate clockwise, thereby switching the backrest 2 from a first seating state to a second seating state. When the first adjustment button 6 is rotated in a second direction, the control circuit activated can cause the drive unit 3 to rotate counterclockwise, thereby switching the backrest 2 from a second seating state to a first seating state.

[0112] In some embodiments, please refer to Figure 10The vehicle may also include a second adjustment button 20. The second adjustment button 20 is attached to the outside of the vehicle body, for example, the second adjustment button 20 is attached to the side panel 30 of the vehicle body. In some examples, the second adjustment button 20 may also extend into the inside of the vehicle so that the second adjustment button 20 can be operated from both the outside and inside of the vehicle.

[0113] The second adjustment button 20 is electrically connected to the drive unit 3 and is used to drive the backrest 2 to switch between a folded state and a seated state. In this way, the driver and passengers can control the drive unit 3 from outside the vehicle by using the second adjustment button 20 to adjust the backrest 2 between the seated and folded states, thus facilitating the adjustment of the backrest 2.

[0114] In some examples, the second adjustment button 20 can be electrically connected to the controller, so that the controller can be electrically connected to the drive unit 3. The second adjustment button 20 can also be electrically connected to the drive unit 3 via a control circuit. The switching of the backrest 2 between a sitting state and a folded state via the second adjustment button 20 is analogous to the switching of the backrest 2 between a first sitting state and a second sitting state via the first adjustment button 6, and will not be described in detail here.

[0115] In some embodiments, the seat 10 further includes a first sensor disposed on the seat cushion 12, for detecting whether there is a person on the seat 10, so as to avoid switching the backrest 2-way to a folding state when there is a person on the seat 10. Exemplarily, the first sensor can be a pressure sensor, a photoelectric sensor, etc., and this application does not specifically limit it.

[0116] This avoids the backrest switching to a two-way folding state when someone is in seat 10, thus preventing injury to the driver and passengers and improving their safety and riding experience.

[0117] In some examples, the first sensor may be electrically connected to the controller to transmit a signal that a person is detected on the seat 10 to the controller, so that the controller controls the drive 3 to stop working, thereby preventing the backrest 2 from rotating.

[0118] In some other examples, the first sensor can also be electrically connected to the control board of the drive unit 3. When the first sensor detects that someone is on the seat 10, the control board of the drive unit 3 can directly control the drive unit 3 to cut off the power to avoid the drive unit 3 from working, thereby preventing the backrest 2 from rotating.

[0119] In some embodiments, the seat 10 further includes a second sensor disposed on the backrest 2, which is used to detect whether there is an item on the backrest 2 when the backrest 2 is in a folded state, so as to prevent the backrest 2 from switching to a sitting state when there is an item on the backrest 2.

[0120] This prevents the backrest 2 from switching to a sitting position when there are items on it, thus preventing items on the backrest 2 from slipping off and causing damage.

[0121] The structure and operation of the second sensor can be the same as those of the first sensor, and will not be described in detail here.

[0122] The following section describes the state switching of the backrest 2, taking the example that the drive unit 3 is a Hall dual-speed motor, and the drive unit 3, the first sensor, and the second sensor are all electrically connected to the controller.

[0123] When the backrest 2 switches from a folded state to a seated state, the driver or passenger operates the second adjustment button 20. After receiving the signal from the second adjustment button 20, the controller determines whether there is an item on the backrest 2 based on the signal detected by the second sensor. If there is an item, the controller stops supplying current and voltage to the drive unit 3, causing the drive unit 3 to stop working and preventing the backrest 2 from rotating. If there is no item, the controller outputs a larger current and voltage to the drive unit 3, causing the drive unit 3 to run at high speed. This drives the first angle adjuster 51 and the second angle adjuster 52 to rotate via the first synchronous rod 53, thereby causing the backrest 2 to rotate away from the seat cushion 12. During this process, the backrest 2 will drive the seat cushion 12 and the second transmission component 42 to move backward and upward via the first transmission component 41 until the seated state is switched. At this point, the controller stops supplying current and voltage to the drive unit 3, causing the drive unit 3 to stop working.

[0124] When the backrest 2 switches from a seated position to a folded position, the driver or passenger operates the second adjustment button 20. After receiving the signal from the second adjustment button 20, the controller determines whether there is anyone on the backrest 2 based on the signal detected by the first sensor. If someone is present, the controller stops supplying current and voltage to the drive unit 3, preventing it from operating and thus avoiding injury. If no one is present, the controller outputs a larger current and voltage to the drive unit 3, causing it to run at high speed. This, in turn, drives the first angle adjuster 51 and the second angle adjuster 52 to rotate via the first synchronizing rod 53, thereby causing the backrest 2 to rotate towards the seat cushion 12. During this process, the backrest 2, through the first transmission component 41, causes the upper ends of the seat cushion 12 and the second transmission component 42 to move forward and downward until the folded position is reached. At this point, the controller stops supplying current and voltage to the drive unit 3, causing it to stop operating.

[0125] When the backrest 2 switches from the first seating position to the second seating position, the driver or passenger operates the first adjustment button 6. After receiving the signal from the first adjustment button 6, the controller controls the supply of a lower current and voltage (e.g., the rated voltage) to the drive component 3, so that the drive component 3 runs at a low speed. This drives the first adjuster 51 and the second adjuster 52 to rotate via the first synchronizer 53, which in turn drives the backrest 2 to rotate via the first transmission component 41, switching the backrest 2 to the second seating position. Then, the controller stops the drive component 3. During this process, the backrest 2 will lift the front end of the seat cushion 12 via the first transmission component 41 to prevent the driver or passenger from sliding downwards when sitting on the seat 10.

[0126] The process of switching backrest 2 from the second seating state to the first seating state is the reverse of the process of switching backrest 2 from the first seating state to the second seating state, and will not be described in detail here.

[0127] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
