Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a seat assembly and a vehicle. Background Technology

[0002] With societal development and the increasing number of vehicles, the traffic accident rate is also rising. In reality, it's common to see incidents where occupants are trapped inside vehicles due to deformation after a collision. One reason for these accidents is that during a collision, the occupants' legs have nowhere to go when subjected to the crushing force from the front, leading to entrapment and injury, significantly impacting their safety. Summary of the Invention

[0003] This application provides a seat assembly and a vehicle that can protect the legs of occupants in the event of a collision.

[0004] In a first aspect, this application provides a seat assembly, comprising: A seat cushion, comprising a fixedly disposed seat cushion body and a leg support portion movably connected to the seat cushion body; The backrest is movably connected to the seat cushion body; A movable component, connected to the leg support and the backrest, is controllable to move the backrest and the leg support to the collision area upon impact.

[0005] In an optional embodiment, the movable component includes a connecting component disposed between the leg support and the backrest. The leg support is fixedly connected to the backrest via the connecting component, so that the movable component drives the backrest and the leg support to move synchronously.

[0006] In an optional embodiment, the active component further includes a drive component connected to the connecting component, the drive component including a first slide rail and a first slider slidably disposed on the first slide rail; wherein, the first slide rail is disposed on the seat cushion body, the first slider is fixedly connected to the backrest, and the first slider is controllable to drive the backrest to move along the first slide rail to the collision area.

[0007] In an optional embodiment, two first sliders are provided, spaced apart on the first slide rail, and the two first sliders are controlled to move the backrest along the first slide rail to the collision area.

[0008] In an optional embodiment, the first slide rail is made of an electromagnet, and the housing of the first slider is made of a metal material. When the backrest and the leg support are located in the collision area, the first slide rail and the first slider attract each other.

[0009] In an optional embodiment, the movable component further includes a second slide rail and a second slider slidably disposed on the second slide rail; wherein the second slider is fixedly connected to the connecting component, and the second slider is controlled to drive the connecting component to move along the second slide rail, so as to move the backrest and the leg support to the collision area.

[0010] In an optional embodiment, when the leg support is located in the collision area, the seat cushion body has a leg groove for securing the legs of the occupant.

[0011] In an optional embodiment, the seat assembly further includes a seat belt connected to the leg support and / or the backrest, the seat belt being movable with the leg support to the collision zone, the seat belt being used to secure the occupant in the collision zone.

[0012] Secondly, this application provides a vehicle including: the seat assembly described in any of the above embodiments.

[0013] In an optional embodiment, the vehicle further includes a collision module and a control module connected to each other. The collision module is used to collect collision information and generate a collision signal. The collision module can send the collision signal to the control module, and the control module controls the activity of the active components according to the collision signal.

[0014] The seat assembly provided in this application has at least the following advantages: In the event of a collision, the movable components can move the backrest and leg support to the collision zone. When occupants experience forward pressure, they can move towards this zone to avoid the impact, thus improving occupant safety, particularly leg safety. Furthermore, this application abandons the traditional method of moving the entire seat and adopts a partitioned movement structure, controlling the backrest and leg support separately. On one hand, compared to the entire seat, the backrest and leg support are relatively lighter, making high-speed movement easier. On the other hand, most existing vehicle seat assemblies can be adjusted automatically or manually along the vehicle's length, making it inconvenient to add movable components to move the seat assembly forward and backward at high speeds. Therefore, this application uses a partitioned movement design to accommodate the overall forward and backward adjustment of the seat assembly. Attached Figure Description

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0020] Please refer to Figure 1 and Figure 2 This application provides a vehicle (not shown) that includes a seat assembly, a collision module 50, and a control module.

[0021] The seat assembly includes a seat cushion, a backrest 10, and a movable component. The seat cushion includes a fixedly mounted seat cushion body 22 and a leg support 21 movably connected to the seat cushion body 22, meaning the leg support 21 can move relative to the seat cushion body 22. The backrest 10 is also movably connected to the seat cushion body 22 and can move relative to it. The movable component is connected to the leg support 21 and the backrest 10. In the event of a collision, the movable component can controllably move the backrest 10 and the leg support 21 to the area to be impacted, thereby avoiding the crushing force in front of the seat and protecting the occupants.

[0022] Specifically, the control module includes a body control module 42 and a seat control module 41. The collision module 50 is used to collect collision information and generate collision signals. The collision module 50 can send collision signals to the body control module 42. The body control module 42 sends seat control commands to the seat control module 41 according to the collision signals. The seat control module 41 controls the moving components to move the backrest 10 and leg support 21 to the collision area according to the seat control commands.

[0023] It should be noted that in this embodiment, the body control module 42 can be the vehicle controller, the seat control module 41 can be a microcontroller, CPU, etc., that controls moving components separately, and the collision module 50 can be a collision sensor, lidar, etc., located on the vehicle body, but is not limited to these. The collision area refers to the area away from the point of collision, including but not limited to the rear area of ​​the backrest 10, that is, the area of ​​the backrest 10 away from the front of the vehicle. Of course, in some other embodiments, the collision area can also be the rear side area of ​​the backrest 10, etc.

[0024] As described above, when a collision occurs or is about to occur, the movable components can move the backrest 10 and leg support 21 to the collision area. When the occupants are subjected to frontal compression, they can move towards the collision area to avoid the frontal compression, thereby improving the safety factor of the occupants after a collision, especially improving the leg safety factor. At the same time, this application abandons the traditional whole seat movement and adopts a partitioned movement structure, that is, the backrest 10 and leg support 21 are controlled separately. On the one hand, compared with the whole seat, the backrest 10 and leg support 21 are relatively light and easier to move at high speed. On the other hand, most existing vehicle seat assemblies can be adjusted automatically or manually along the length of the vehicle, which is not convenient for adding a movable component to drive the seat assembly to move back and forth at high speed. Therefore, this application adopts a partitioned movement form to be compatible with the overall back and forth adjustment of the seat assembly.

[0025] The specific structural form of the movable components can be varied. For example, telescopic devices can be provided on the rear side of both the backrest 10 and the leg support 21 to move them to the collision area and return them to their initial position. The telescopic device can be a cylinder, an electric telescopic rod, a hydraulic rod, etc., but is not limited to these. Alternatively, a linkage structure can be provided below both the backrest 10 and the leg support 21. This linkage structure, when controlled, can swing the backrest 10 and the leg support 21 to the collision area and return them to their initial position.

[0026] In one embodiment, the movable component includes a connecting component disposed between the leg support 21 and the backrest 10. The leg support 21 is fixedly connected to the backrest 10 through the connecting component, so that the movable component drives the backrest 10 and the leg support 21 to move synchronously. This avoids the risk of a decrease in the riding experience and safety of the driver and passengers caused by one of the backrest 10 and the leg support 21 moving first and the other moving later, thereby enhancing the riding experience and safety performance of the driver and passengers.

[0027] like Figure 1 In the illustrated embodiment, the connecting assembly includes a first connecting rod 311 and a second connecting rod 312. The two ends of the first connecting rod 311 are fixedly connected to the leg support portion 21 and the second connecting rod 312, respectively, and the second connecting rod 312 is fixedly connected to the backrest 10, thereby fixing the leg support portion 21 and the backrest 10 together. Furthermore, two first connecting rods 311 are provided, both of which are fixedly connected to the leg support portion 21 and the second connecting rod 312, to improve the reliability of the connection between the leg support portion 21 and the backrest 10.

[0028] In one embodiment, the active component further includes a drive component connected to the connecting component. The drive component includes a first slide rail 321 and a first slider 322 slidably disposed on the first slide rail 321. The first slide rail 321 is disposed on the seat cushion body 22, and the first slider 322 is fixedly connected to the backrest 10. The first slider 322 is controlled to drive the backrest 10 to move along the first slide rail 321 so that the backrest 10 moves to the collision area when a collision occurs.

[0029] The first sliding member 322 can be a linear motor, which can move along the first slide rail 321 to drive the first sliding member 322 to move along the first slide rail 321, thereby driving the backrest 10 to move. It is understood that the first sliding member 322 can be an integral device of the linear motor, including but not limited to the linear motor body and the housing.

[0030] In other embodiments, the first sliding member 322 can also be a rotary motor. In this case, the first slide rail 321 can be provided with a transmission component. The rotary motor, through transmission cooperation with the first slide rail 321, can move along the first slide rail 321, thereby driving the first sliding member 322 to move along the first slide rail 321, and thus driving the backrest 10 to move. Similarly, the first sliding member 322 can be an integral device of the rotary motor, including but not limited to the rotary motor body and the housing. The transmission component can be a gear and rack drive, a lead screw and nut drive, etc., which are not specifically limited in this embodiment.

[0031] In a further embodiment, two first sliding members 322 are provided, spaced apart on the first slide rail 321. The two first sliding members 322 are controllably movable to move the backrest 10 along the first slide rail 321 to the collision area. By providing two first sliding members 322, the reliability and speed of the backrest 10's movement are improved. Furthermore, a rigid connecting member 324 can be provided between the two first sliding members 322 to ensure synchronized movement.

[0032] In one embodiment, the first slide rail 321 is made of an electromagnet, and the outer shell of the first sliding member 322 is made of a metal material, including but not limited to iron, nickel, and cobalt. When the backrest 10 and the leg support 21 are located in the collision area, the first slide rail 321 can be energized and attracted to the first sliding member 322, so that the backrest 10 is fixed relative to the first slide rail 321, thereby locking the backrest 10 onto the first slide rail 321. Since the backrest 10 and the leg support 21 are fixedly connected, when the first slide rail 321 is energized, the leg support 21 is also locked in the collision area, thereby enhancing the stability of the backrest 10 and the leg support 21 when a collision occurs.

[0033] In one embodiment, two first slide rails 321 may be provided, and the two first slide rails 321 may be spaced apart along the width direction of the vehicle. Both first slide rails 321 may be provided with the first sliding member 322 described in the above embodiment. In this way, the stability and reliability of the backrest 10 during movement can be enhanced.

[0034] In one embodiment, the movable component further includes a second slide rail and a second slider 323 movably disposed on the second slide rail; wherein the second slider 323 is fixedly connected to the connecting component, and the second slider 323 is controllable to drive the connecting component to move along the second slide rail, thereby moving the backrest 10 and the leg support 21 to the collision area. By providing a second slide rail and a second slider 323 on the basis of the first slide rail 321 and the first slider 322, the moving speed of the backrest 10 and the leg support 21 and the reliability of movement when a collision occurs can be improved, thereby improving the safety factor of the occupants.

[0035] The second slide rail and the second sliding member 323 are disposed at the lower end of the second connecting rod 312. Their specific structure and arrangement can be referred to the structure and arrangement of the first slide rail 321 and the first sliding member 322 described above. This embodiment will not repeat the details.

[0036] In one embodiment, when the leg support 21 is located in the collision zone, the seat cushion body 22 forms a leg groove 221 for securing the occupant's legs. In other words, when a collision occurs, as the leg support 21 moves to the collision zone under the influence of the movable components, a leg groove 221 is formed at the initial position of the leg support 21. When the occupant is subjected to forward pressure, their legs can move to the leg groove 221, which provides restraint and limits any uncontrolled leg movement, thus protecting the occupant's legs. Both the leg support 21 and the seat cushion body 22 are made of flexible material to facilitate the formation of the aforementioned leg groove 221.

[0037] In one embodiment, the seat assembly also includes a seat belt connected to the leg support 21 and / or the backrest 10. Specifically, the seat belt is connected to the backrest 10 for wearing on the occupant's torso. The seat belt moves with the leg support 21 to the collision zone and is used to secure the occupant in the collision zone. Since the backrest 10, leg support 21, and occupant all move to the collision zone, this embodiment configures the seat belt to move with the leg support 21 and backrest 10 to better secure the occupant, ensuring that the occupant remains within the seat belt's protection range even in the collision zone. Furthermore, because the seat belt moves with the leg support 21 and backrest 10, it simultaneously moves the occupant to the collision zone during the movement of the backrest 10 and leg support 21, eliminating the need for the occupant to move independently or be passively moved by pressure, significantly improving the occupant's safety during a collision.

[0038] In another embodiment, the seat belt can be set in its original position. When the control module receives a collision signal, it can control the seat belt to retract or extend to accommodate the occupants moving to the collision area, so that the occupants are also within the protection range of the seat belt in the collision area.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
