Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an automobile seat and vehicle. Background Technology

[0002] With the development of the automotive industry, users have increasingly higher requirements for the comfort of car seats. Car seats mainly consist of a seat cushion and a backrest, with the backrest located at the rear of the seat cushion. To meet users' needs for reclining during long journeys or temporary rest, most car seat designs on the market now support a large angle of backrest reclining, even to a near-horizontal position.

[0003] However, when the backrest is reclined at a large angle, there is often a significant height difference between the backrest and the end of the seat cushion, creating a distinct step structure between them. This height difference can cause localized pressure on the user's lumbar region. Utility Model Content

[0004] In view of this, embodiments of this application provide a car seat and vehicle to solve the problem that there is a significant height difference between the backrest and the rear end of the seat cushion when the backrest is reclined at a large angle in existing car seats.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a car seat, comprising:

[0007] A support frame, wherein a support beam is fixedly mounted at one end of the support frame;

[0008] A seating area, which is rotatably connected to the support beam;

[0009] An adjustment part is rotatably mounted on the support frame;

[0010] A transmission part is fixed on the adjustment part, the transmission part is located below the seating part, and the transmission part is at least partially in contact with the end of the seating part away from the support beam, so as to cooperate with the support beam to support the seating part;

[0011] A drive assembly is disposed on the support frame and is connected to the adjustment part in a transmission manner. The drive assembly is configured to drive the adjustment part to rotate, so that the transmission part pushes the seating part to rotate relative to the support beam.

[0012] In one possible implementation of this application, the adjustment part includes a first adjustment part and a second adjustment part, the first adjustment part and the second adjustment part are disposed on both sides of the support frame, the two ends of the transmission part are connected to the first adjustment part and the second adjustment part respectively, and the drive component is connected to at least one of the first adjustment part and the second adjustment part.

[0013] In one possible implementation of this application, the transmission part includes a first transmission rod and a second transmission rod. Both ends of the first transmission rod are connected to the second transmission rod, and the extension direction of the first transmission rod intersects the extension direction of the second transmission rod. The first transmission rod contacts the bottom of the seating part, and the two second transmission rods are respectively connected to the first adjustment part and the second adjustment part at the ends away from the first transmission rod.

[0014] In one possible implementation of this application, the included angle between the first transmission rod and the second transmission rod is an obtuse angle.

[0015] In one possible implementation of this application, a first mounting member is fixed on the support frame, the first mounting member extending at least partially below the support frame and rotatably connected to the adjustment part.

[0016] In one possible implementation of this application, the driving assembly includes a drive motor, a lead screw, and a slider. The drive motor is rotatably mounted on the support frame. The lead screw is driven by the output end of the drive motor. The slider is rotatably connected to the adjustment part. The slider is also threadedly connected to the lead screw.

[0017] In one possible implementation of this application, a second mounting member is provided on the support beam, the second mounting member extending at least partially below the support frame and being rotatably connected to the drive motor.

[0018] In one possible implementation of this application, the seating portion includes a seat frame spring, the two ends of which are rotatably connected to the support beam and the transmission portion, respectively.

[0019] In one possible implementation of this application, the seating portion further includes a seat cushion that rests on the seat frame spring.

[0020] Secondly, embodiments of this application provide a vehicle, including a vehicle body and a car seat as described in any of the first aspects, wherein the support frame of the car seat is installed in the vehicle body.

[0021] In the car seat and vehicle provided in this application embodiment, the car seat is provided with a support frame, a seating part, an adjustment part, a transmission part, and a drive assembly. The adjustment part is rotatably mounted on the support frame, and the seating part is rotatably connected to the support beam on the support frame. The transmission part is fixed on the adjustment part and is located below the seating part, contacting the bottom of the seating part away from the support beam. The transmission part and the support beam cooperate to support the seating part. The drive assembly can drive the adjustment part to rotate. When the adjustment part rotates, it will drive the transmission part to rotate synchronously. When the transmission part rotates, it will push the end of the seating part that is in contact with the transmission part to move, thereby causing the seating part to rotate around its connection with the support beam, changing the height of one end of the seating part. When the car seat is folded down, the height of the end of the seating part adjacent to the backrest of the car seat can be made suitable with the height of the backrest, avoiding a height difference between the two, thereby avoiding the problem of local pressure on the user's waist area, and effectively improving the comfort of the car seat after it is folded down.

[0033] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. A vehicle includes a body, which generally has wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0034] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0035] The vehicle provided in this application embodiment also includes a car seat, which is disposed in the vehicle body and is used for users to sit on. One or more car seats may be provided, which can be determined according to the interior space and the purpose of the vehicle.

[0036] For example, some vehicles may have four car seats, two in the front and two in the rear.

[0037] For example, in some vehicles, only two car seats are provided in the driver's compartment, and no seats are provided in the remaining areas.

[0038] It is understandable that this is merely an example of how car seats can be arranged, not a limitation.

[0039] Please see Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, the car seat includes a support frame 100 and a seating section 200.

[0040] The support frame 100 is the load-bearing component of the entire car seat. It can be connected to the vehicle body and support other components. One end of the support frame 100 is provided with a support beam 110. The support beam 110 can be fixed to the support frame 100 by common methods such as welding and bolt connection. The seating part 200 is supported by the support frame 100 and is used for users to sit on.

[0041] The support frame 100 extends along the X direction, while the support beam 110 can extend along the Y direction. That is, the extension directions of the support beam 110 and the support frame 100 intersect, and the two ends of the support beam 110 are connected to the two sides of the support frame 100 extending along the X direction.

[0042] Understandably, the support frame 100 can be of any shape, as long as it can effectively provide support.

[0043] Car seats typically also include a backrest, which is rotatably connected to the support frame 100. The backrest is located at the rear end of the seating section 200, and the backrest can be adjusted to the tilt angle according to seating needs, making it convenient for the user to sit or lie down.

[0044] When the backrest is tilted at a large angle to facilitate the user's reclining, the backrest flips over, creating a height difference between the backrest and the rear end of the seating section 200, forming a step-like structure. At this time, the end of the backrest will press against part of the user's waist, resulting in severe lumbar support and affecting the user's comfort.

[0045] In this embodiment, the car seat also includes an adjustment unit 300, a transmission unit 400, and a drive assembly 500.

[0046] The seating section 200 is rotatably connected to the support beam 110, for example, the front end or the area near the front end is rotatably connected to the support beam 110. The adjustment section 300 is rotatably connected to the support frame 100. The transmission section 400 is fixed on the adjustment section 300. The transmission section 400 is located below the seating section 200 and at least partially contacts the rear end of the seating section 200, that is, the transmission section 400 at least partially contacts the end of the seating section 200 away from the support beam 110. The drive assembly 500 is provided on the support frame 100 and is connected to the adjustment section 300. The drive assembly 500 can drive the adjustment section 300 to rotate. The rotation of the adjustment section 300 drives the transmission section 400 to rotate, thereby pushing the rear end of the seating section 200 to move and changing the height of the rear end of the seating section 200.

[0047] Specifically, when the backrest is reclined, the user can control the drive assembly 500 to rotate according to their own comfort. The drive assembly 500 drives the adjustment part 300 to rotate. When the adjustment part 300 rotates, it drives the transmission part 400 to rotate synchronously. When the transmission part 400 rotates, it pushes the end of the seating part 200 that is in contact with the transmission part 400 to move. This causes the seating part 200 to rotate around the connection point with the support beam 110, changing the height of the rear end of the seating part 200. This makes the height of the connection point between the rear end of the seating part 200 and the backrest suitable, reducing or eliminating the height difference between the rear end of the seating part 200 and the backrest. This avoids the problem of local pressure on the user's lumbar area and effectively improves the comfort of the car seat after it is reclined.

[0048] Furthermore, in some embodiments of this application, the adjustment part 300 includes a first adjustment part 310 and a second adjustment part 320, which are respectively disposed on both sides of the support frame 100.

[0049] For example, the support frame 100 includes two end beams and two side beams. The two side beams extend along the X direction, and the two end beams extend along the Y direction. The two end beams are respectively located at both ends of the side beams, and the two ends of the end beams are connected to the ends of the two side beams, for example by welding, bolting, or directly integrally formed.

[0050] The shapes of the side beams and end beams can be adjusted according to the structural adaptability of the passenger compartment 200 and the vehicle body. They do not necessarily have to be straight bars, and can also be bent in some areas.

[0051] It is understood that this is merely an example of the structure supporting the frame 100, and not a limitation thereof.

[0052] For example, the first adjustment part 310 and the second adjustment part 320 can be rods or plates, as long as they can be rotatably connected to the support frame 100, connected to the drive assembly 500, and effectively support the transmission part 400.

[0053] The first adjustment part 310 and the second adjustment part 320 can be arranged opposite to each other on the two side beams. The two ends of the transmission part 400 are connected to the first adjustment part 310 and the second adjustment part 320 respectively. The first adjustment part 310 and the second adjustment part 320 can effectively support the two ends of the transmission part 400, so as to improve the support effect of the transmission part 400 on the seating part 200 and improve the stability of the seating part 200.

[0054] The two ends of the transmission unit 400 are fixedly connected to the first adjustment unit 310 and the second adjustment unit 320, respectively. Whenever one of the first adjustment unit 310 or the second adjustment unit 320 rotates, the other and the transmission unit 400 will rotate synchronously under its drive. At this time, the drive assembly 500 only needs to be connected to one of the first adjustment unit 310 or the second adjustment unit 320 to achieve height adjustment of the rear end of the seating unit 200, facilitating installation and simplifying the structure while reducing the weight of the car seat.

[0055] Furthermore, in some embodiments of this application, a first mounting member 330 is fixed on the support frame 100. The first mounting member 330 extends at least partially to the lower part of the support frame 100 and is rotatably connected to the adjustment part 300, which can prevent the adjustment part 300 from occupying the space above the support frame 100, that is, it will not affect the installation of the seating part 200.

[0056] For example, a first mounting component 330 is provided on each of the two side beams of the support frame 100. The first mounting component 330 can be connected to the side beam by common methods such as welding or bolting.

[0057] The first mounting member 330 can be an L-shaped plate or rod, with one end welded to the outer side of the side beam and the other end extending from below the side beam around the side beam to between the two side beams. The first adjustment part 310 or the second adjustment part 320 is rotatably connected to the part of the first mounting member 330 extending to the two side beams through common components such as a pivot or hinge.

[0058] It is understandable that the tilt angle of the first adjustment part 310 and the second adjustment part 320 relative to the end beam, as well as the distance between the first adjustment part 310 and the second adjustment part 320 and the seating part 200, can be adjusted by the structure of the first mounting part 330.

[0059] Furthermore, in some embodiments of this application, the transmission part 400 includes a first transmission rod 410 and a second transmission rod 420. Both ends of the first transmission rod 410 are connected to the second transmission rod 420, and the extension direction of the first transmission rod 410 intersects with the extension direction of the second transmission rod 420, so that the first transmission rod 410 and the second transmission rod 420 form a U-shaped structure. The first transmission rod 410 contacts the bottom of the seating part 200, supports the seating part 200, and adjusts the height of the rear end of the seating part 200. The two second transmission rods 420 are connected to the first adjustment part 310 and the second adjustment part 320 respectively at the ends away from the first transmission rod 410. The first adjustment part 310 and the second adjustment part 320 support the first transmission rod 410 and the second transmission rod 420, and drive the first transmission rod 410 and the second transmission rod 420 to rotate synchronously, thereby effectively adjusting the height of the rear end of the seating part 200.

[0060] For example, the angle between the first transmission rod 410 and the second transmission rod 420 is an obtuse angle, so that the length of the first transmission rod 410 is smaller than the width of the support frame 100, thus avoiding interference between the transmission part 400 and the support frame 100.

[0061] When connecting the second transmission rod 420 and the first adjustment part 310 or the second adjustment part 320, in order to facilitate installation, the end of the second transmission rod 420 away from the first transmission rod 410 can be bent into a shape that fits the surface of the first adjustment part 310 or the second adjustment part 320, so as to increase the contact surface between the two during welding and improve the welding effect.

[0062] It is understandable that the transmission unit 400 can also be other structures, as long as it can effectively support the seating unit 200 and does not interfere with the support frame 100.

[0063] Furthermore, in some embodiments of this application, the drive assembly 500 includes a drive motor 510, a lead screw 520, and a slider 530. The drive motor 510 is rotatably mounted on the support frame 100. It can be directly rotatably connected to the support frame 100, or it can be indirectly rotatably connected to the support frame 100 through a structure such as a mounting bracket, as long as the drive motor 510 can rotate relative to the support frame 100. The lead screw 520 is driven by the output end of the drive motor 510, and the drive motor 510 drives the lead screw 520 to rotate. The slider 530 is rotatably connected to the adjustment part 300, and the slider 530 is also threadedly connected to the lead screw 520. When the lead screw 520 rotates, the slider 530 can move along the lead screw 520.

[0064] The drive motor 510 can be a servo motor. The rotation direction of the lead screw 520 is controlled by the forward and reverse rotation of the motor, which in turn controls the movement direction of the slider 530 relative to the lead screw 520, so that the first adjustment part 310, the second adjustment part 320 and the transmission part 400 rotate in the corresponding direction to adjust the height of the tail end of the seating part 200.

[0065] The drive motor 510 can rotate relative to the support frame 100, and the tilt angle of the drive motor 510 can be adjusted. When the first adjustment part 310 and the second adjustment part 320 rotate, the positions of the drive motor 510, the lead screw 520 and the slider 530 can be adapted to them.

[0066] In addition, a second mounting component 540 can be added to connect the drive motor 510 and the support frame 100.

[0067] For example, the second mounting member 540 is welded to the bottom of the support beam 110, and the drive motor 510 is rotatably connected to the second mounting member 540 through a structure such as a rotating shaft and a hinge. The end of the second mounting member 540 connected to the drive motor 510 also extends to the bottom of the support frame 100 and extends towards the transmission part 400, so that the drive motor 510, the lead screw 520 and the slider 530 can also be located on the side of the support frame 100 away from the seat part 200, leaving sufficient space for the installation of the seat part 200.

[0068] For example, the first adjustment part 310 / second adjustment part 320 is rotatably connected to the first mounting member 330 via a first rotating shaft, the extension direction of which can support the beam 110 parallel. The first adjustment part 310 and the slider 530 are rotatably connected via a second rotating shaft, the extension direction of which is the same as that of the first rotating shaft. The drive motor 510 is rotatably connected to the second mounting member 540 via a third rotating shaft, the extension direction of which is the same as that of the first and second rotating shafts. Thus, when adjusting the height of the rear end of the seating part 200, the drive motor 510, lead screw 520, slider 530, first adjustment part 310, second adjustment part 320 and transmission part 400 can cooperate with each other without interfering with each other.

[0069] It is understood that the drive component 500 may also be other structures, such as a servo motor that is directly connected to the first adjustment unit 310 or the adjustment unit 300, or other telescopic structures that can drive the first adjustment unit 310 or the second adjustment unit 320 to rotate. This is only an example and not a limitation.

[0070] Furthermore, in some embodiments of this application, the seating section 200 includes a seat frame spring 210, the two ends of which are rotatably connected to the support beam 110 and the transmission section 400, respectively.

[0071] For example, multiple hooks can be provided at both ends of the seat frame spring 210. One hook is attached to the support beam 110, and the other hook is attached to the first transmission rod 410. When it is necessary to adjust the height of the tail end of the seat frame spring 210, the hook can rotate relative to the support beam 110 and the first transmission rod 410, making the connection extremely convenient.

[0072] It is understood that the seat spring 210 can also be rotatably connected to the support beam 110 and the transmission unit 400 in other common ways, and is not limited to the above-mentioned methods.

[0073] Furthermore, the seating section 200 also includes a seat cushion 220, which is attached to the seat frame spring 210. The seat cushion 220 can be made of common materials such as foam and sponge, and is mainly used to contact the user to give the user a more comfortable sitting experience.

[0074] For example, the seat frame spring 210 can be bent into a corresponding shape according to the usage requirements, and then the corresponding seat cushion 220 can be attached to the seat frame spring 210. The structure of the seat cushion 220 and the seat frame spring 210 can be adjusted according to the space inside the vehicle and the actual riding comfort.

[0075] It is understandable that the seating section 200 can also be other existing structures, as long as it can be effectively connected to the support beam 110 and the transmission section 400. The above is just an example and not a limitation.

[0076] 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.
