Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an electrically adjustable seat cushion and automotive seat. Background Technology

[0002] Some car seats are equipped with a forward-folding function, meaning the backrest can be rotated forward and folded onto the seat cushion. To ensure that the seat cushion does not interfere with the backrest when it is rotated forward and folded, the seat cushion's basin is lowered forward to make room for the backrest to fold forward.

[0003] In existing car seats, the seat depression adjustment process is generally driven by a motor. The motor drives a telescopic rod to extend, causing the seat to gradually move forward and achieve the depression function. However, this method has poor stability and a complex structure. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an electrically adjustable seat cushion and car seat with simple structure and good motion stability.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose an electrically adjustable seat cushion, comprising:

[0006] Base frame, seat, front support, and drive module;

[0007] The base frame is provided with a sliding groove near its rear end; the rear end of the basin is mounted on the base frame and can slide along the sliding groove; the front end of the basin is hinged to the front end bracket, and the front end bracket is hinged to the base frame.

[0008] The drive module includes a drive motor and a telescopic rod driven by the drive motor. The drive motor is rotatably mounted on the base frame and is located near the rear end of the base frame. The end of the telescopic rod away from the drive motor is hinged to the front end bracket.

[0009] The drive motor drives the telescopic rod to retract, which allows the rear end of the seat to slide forward along the slide groove, changing the tilt angle of the seat and causing the seat to submerge.

[0010] Furthermore, the front support includes a rotating frame, a connecting rod, and a connecting frame connected in sequence. The upper end of the rotating frame is hinged to the seat, the lower end of the rotating frame is hinged to the base frame, one end of the connecting frame is connected to the connecting rod, and the other end extends downward. The telescopic rod is hinged to the end of the connecting frame away from the connecting rod.

[0011] Furthermore, each end of the connecting rod is provided with a rotating frame, and the two ends of the rotating frames are respectively hinged to the base frame and the seat.

[0012] Furthermore, the rotating frame, the connecting rod, and the connecting frame are sequentially and fixedly connected as a whole.

[0013] Furthermore, a motor mounting bracket extends downward from the base frame, and the drive motor is rotatably mounted on the motor mounting bracket.

[0014] Furthermore, the chute includes a smooth section and a downward section, the smooth section being horizontally arranged, and the downward section gradually extending downward from one end closer to the smooth section to the end farther away from the smooth section.

[0015] Furthermore, the downward segment is S-shaped;

[0016] The inner side of the base frame is provided with a supporting sheet metal part that is fixedly connected thereto, and the slide groove is provided on the supporting sheet metal part.

[0017] Furthermore, the rear end of the basin is provided with a guide slider, which is slidably disposed in the groove.

[0018] Furthermore, the number of drive motors is one;

[0019] When the drive motor drives the telescopic rod to retract, and the rear end of the seat slides along the rear end of the slide groove to the front end of the slide groove, the rear end of the seat moves forward a distance greater than or equal to 160mm, and the height of the seat sinking is greater than or equal to 69mm.

[0020] This utility model also proposes a car seat, comprising:

[0021] Backrest and the aforementioned electrically adjustable seat cushion;

[0022] When the seat basin is lowered, the backrest can be flipped forward and folded onto the seat basin.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In this utility model, the adjustable seat cushion includes a base frame, a seat basin, a front support, and a drive module. The drive module includes a drive motor and a telescopic rod. The drive motor drives the telescopic rod to retract, which allows the rear end of the seat basin to slide forward along the slide groove, changing the tilt angle of the seat basin and causing the seat basin to sink. This makes it convenient for the backrest to rotate, flip, and fold onto the seat cushion. The overall structure is simple.

[0025] In this invention, the lowering motion of the tub is driven by the gradual retraction of the telescopic rod. During this process, the length of the telescopic rod gradually becomes shorter, the span becomes smaller, and the stability becomes better and better.

[0026] In this invention, the front support includes a rotating support, a connecting rod, and a connecting frame connected in sequence. The end of the telescopic rod away from the motor is hinged to the connecting piece instead of being directly hinged to the rotating support. This makes the layout of the drive module lower, the Z-axis space larger, the space for the seat to sink more, and frees up space to install more accessories (such as ventilation fans and heating pads).

[0040] Example 1:

[0041] like Figures 1-3 As shown, an electrically adjustable seat cushion of this embodiment mainly includes: a base frame 1, a seat basin 2, a front support 3, and a drive module 4.

[0042] The base frame 1 has a sliding groove 101 near its rear end; the rear end of the basin 2 is mounted on the base frame 1 and can slide along the sliding groove 101; the front end of the basin 2 is hinged to the front support 3, and the front support 3 is hinged to the base frame 1. The drive module 4 includes a drive motor 40 and a telescopic rod 41 driven by the drive motor 40. The drive motor 40 is rotatably mounted on the base frame 1 and is located near the rear end of the base frame 1; the end of the telescopic rod 41 away from the drive motor 40 is hinged to the front support 3. The drive motor 40 drives the telescopic rod 41 to retract, which allows the rear end of the basin 2 to slide forward along the sliding groove 101, changing the tilt angle of the basin 2 and causing the basin 2 to submerge. Specifically, the telescopic rod 41 is an existing structure that can be constructed by a lead screw and a threaded sleeve, which is simple in structure.

[0043] In this embodiment, the adjustable seat cushion includes a base frame 1, a seat basin 2, a front support 3, and a drive module 4. The drive module 4 includes a drive motor 40 and a telescopic rod 41. The drive motor 40 drives the telescopic rod 41 to retract, which allows the rear end of the seat basin 2 to slide forward along the slide groove 101, changing the tilt angle of the seat basin 2 and causing the seat basin 2 to sink. This makes it convenient for the backrest to rotate, flip, and fold onto the seat cushion. The overall structure is simple.

[0044] Furthermore, the lowering motion of the basin 2 is driven by the gradual retraction of the telescopic rod 41. During this process, the length of the telescopic rod 41 gradually becomes shorter, the span becomes smaller, and the stability becomes better and better.

[0045] In existing car seats, the sink 2 descends by the thrust of the telescopic rod 41. That is, the telescopic rod 41 is gradually extended by a motor, causing the sink 2 to descend. As the telescopic rod 41 extends, its length and span increase, and its rigidity gradually decreases, which can easily lead to a decrease in the stability of the sink 2's descending movement.

[0046] In this embodiment, only one drive motor 40 is used, which is sufficient to meet the driving requirements, eliminating the need for dual motors on both sides. In this embodiment, the drive motor 40 retracts via the telescopic rod 41, causing the rear end of the seat basin 2 to slide along the rear end of the slide groove 101 to the front end. At this point, the rear end of the seat basin 2 moves forward a distance greater than or equal to 160mm, and the seat basin 2 lowers to a height greater than or equal to 69mm. This ensures that after the seat basin 2 lowers, sufficient space is created for the backrest to flip forward, resulting in a compact folded car seat that occupies minimal space.

[0047] In this embodiment, the front support 3 includes a rotating frame 31, a connecting rod 32, and a connecting frame 33 connected in sequence. The rotating frame 31, the connecting rod 32, and the connecting frame 33 are fixedly connected as a whole. For example, the rotating frame 31 and the connecting frame 33 can be fixed to the connecting rod 32 by welding. The upper end of the rotating frame 31 is hinged to the basin 2, and the lower end of the rotating frame 31 is hinged to the base frame 1. One end of the connecting frame 33 is fixedly connected to the connecting rod 32, and the other end extends downward. The telescopic rod 41 is hinged to the end of the connecting frame 33 away from the connecting rod 32.

[0048] The connecting frame 33 extends downward from the connecting rod 32, ensuring that the hinge point between the connecting frame 33 and the telescopic rod 41 can be lower. In this embodiment, a rotating frame 31 is provided at each end of the connecting rod 32, and the two ends of the rotating frames 31 are respectively hinged to the base frame 1 and the seat 2. Furthermore, a motor mounting bracket 11 extends downward from the base frame 1, and the drive motor 40 is rotatably mounted on the motor mounting bracket 11. The motor mounting bracket 11 also extends downward from the base frame 1, ensuring that the motor can be mounted lower. Compared with the existing structure, the overall layout of the drive module 4 in this embodiment can be lower, the seat 2 has a larger lowering space, and Z-axis space can be saved.

[0049] In actual use, the front bracket 3 of this embodiment includes a rotating bracket, a connecting rod 32 and a connecting frame 33 connected in sequence. The end of the telescopic rod 41 away from the motor is hinged to the connecting piece instead of being directly hinged to the rotating bracket, which makes the layout of the drive module 4 lower, the Z-axis space larger, the sink 2 can sink more, and more space can be freed up to install more accessories (such as ventilation fans and heating pads).

[0050] The slide 101 in this embodiment includes a smooth section 101A and a downward section 101B. The smooth section 101A is horizontally arranged, and the downward section 101B gradually extends downward from one end close to the smooth section 101A to the other end away from the smooth section 101A. Specifically, the downward section 101B is S-shaped to ensure that the tilt angle adjustment of the basin 2 is smooth and gentle, and the downward movement of the basin 2 is also smooth and gentle.

[0051] Furthermore, a supporting sheet metal part 10 is fixedly connected to the inner side of the base frame 1, and a sliding groove 101 is provided on the supporting sheet metal part 10. By additionally providing the supporting sheet metal part 10 to provide the sliding groove 101, the strength of the base frame 1 itself is not weakened. The sliding groove 101 can be formed by bending the sheet metal during the manufacturing of the supporting sheet metal part 10, without the need for grooving. In addition, a guide slider 20 is provided at the rear end of the basin 2. The guide slider 20 is slidably provided in the sliding groove 101. By moving along the sliding groove 101, the guide slider 20 ensures that the rear end of the basin 2 slides more smoothly.

[0052] When the drive motor 40 in the drive module 4 drives the telescopic rod 41 to retract, thereby driving the rear end of the seat basin 2 from the rear end of the slide groove 101 to the front end of the slide groove 101, during the initial sliding process, the rear end of the seat basin 2 gradually moves horizontally forward, while the front support 3 gradually rises upward, and the overall angle of the seat basin 2 gradually tilts backward, with the tilt angle gradually increasing. As the rear end of the seat basin 2 continues to slide, the front support 3 turns from upright to the front side, and the tilt angle of the seat basin 2 gradually decreases during the subsequent sliding until the seat basin 2 finally approaches horizontal, that is, the seat basin 2 completes the submersion action, at which point the front support 3 is also close to a horizontal state.

[0053] Example 2:

[0054] A foldable car seat according to this embodiment mainly includes:

[0055] The backrest and the electrically adjustable seat cushion in Embodiment 1 mainly include: a base frame 1, a seat basin 2, a front support 3, and a drive module 4. The base frame 1 has a sliding groove 101 near its rear end; the rear end of the seat basin 2 is mounted on the base frame 1 and can slide along the sliding groove 101; the front end of the seat basin 2 is hinged to the front support 3, and the front support 3 is hinged to the base frame 1. The drive module 4 includes a drive motor 40 and a telescopic rod 41 driven by the drive motor 40. The drive motor 40 is rotatably mounted on the base frame 1 and near its rear end; the end of the telescopic rod 41 away from the drive motor 40 is hinged to the front support 3. The drive motor 40 drives the telescopic rod 41 to retract, allowing the rear end of the seat basin 2 to slide forward along the sliding groove 101, changing the tilt angle of the seat basin 2 and causing the seat basin 2 to subside.

[0056] Optionally, a mounting bracket for backrest installation can be provided on the base frame 1. The backrest is rotatably mounted on the mounting bracket, and the backrest tilt angle can be electrically adjusted by providing tilt adjusters on both sides of the backrest. The backrest can rotate relative to the adjustable seat cushion to facilitate tilt angle adjustment and folding.

[0057] In actual use, when the seat basin 2 is lowered, the backrest can be flipped forward and folded onto the seat basin 2, ensuring that the backrest can be flipped flat onto the seat basin 2. After being flipped into place, the folded size is small and takes up little space.

[0058] In this design, the overall structure of the electrically adjustable seat cushion is simple, with good motion stability, a large Z-axis space, which facilitates the installation of other accessories, and allows for a larger space for the seat basin 2 to submerge.
