Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a car seat that can be tilted forward and adjusted. Background Technology

[0002] In daily vehicle use, people often need more trunk space to store goods (or luggage). Most vehicles on the market achieve this by folding the backrest of the seat frame forward and then manually or through motor adjustment to flip the backrest and seat forward together by 90 degrees. However, due to the inherent structural limitations of car seats, the maximum forward folding angle is only 90 degrees, which often still cannot meet passengers' space needs. Furthermore, the protruding structure after the seat cushion is folded down is unavoidable, affecting the aesthetics. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a car seat with forward tilt adjustment is provided to solve the problem that the forward tilt angle of existing car seat cushion frames is small, affecting the utilization of space in the three rows.

[0004] To achieve the above objectives, a forward-tilting adjustable car seat is provided, comprising:

[0005] Bracket, installed on the car floor;

[0006] The seat frame and the support are provided with at least two links. One end of each link is fixedly connected to the seat frame, and the other end of the link is rotatably connected to the support, so that the seat frame can be flipped and connected to the support.

[0007] A drive mechanism, which is mounted on the seat frame or support, is used to drive the seat frame to flip forward relative to the support.

[0008] Furthermore, the other end of each link is rotatably connected to the bracket via a hinge shaft;

[0009] The drive mechanism includes a motor, whose drive shaft is fixedly connected to the hinge shaft to drive the hinge shaft to rotate relative to the bracket.

[0010] Furthermore, it also includes an assist mechanism located between the hinge axis and the bracket to provide assistance for the flipping of the seat frame.

[0011] Furthermore, the assist mechanism includes a leaf spring, one end of which is connected to a bracket and the other end of which is connected to a hinge shaft to provide assistance for the seat frame to flip forward or backward.

[0012] Furthermore, the assist mechanism includes a first leaf spring and a second leaf spring arranged in opposite directions on the hinge shaft. One end of the first leaf spring and the second leaf spring are respectively connected to the bracket, and the other end is respectively connected to the hinge shaft. The first leaf spring and the second leaf spring respectively provide assistance for the seat frame to flip forward and backward.

[0013] Furthermore, the drive mechanism includes a motor and a concentric angle adjuster disposed between any one of the at least two links and the bracket. The motor is connected to the concentric angle adjuster via a synchronizing rod to drive the link to rotate relative to the bracket.

[0014] Furthermore, two connecting rods are arranged opposite each other between the seat cushion frame and the support;

[0015] The drive mechanism includes a motor and angle adjusters respectively disposed between two connecting rods and the bracket. The two angle adjusters are connected by a synchronizing rod, which passes through the motor so that the motor drives the connecting rods to rotate relative to the bracket through the synchronizing rod.

[0016] Furthermore, a boss is formed at the rear end of the car floor, the seat frame is mounted on the boss, and the bracket is set on the front side wall of the boss. After the seat frame is flipped forward, the seat frame is set in front of the front side wall and the upper part of the seat frame is lower than the top surface of the boss.

[0017] Furthermore, a seat back is mounted on the seat cushion frame.

[0018] The beneficial effect of this utility model is that the front end of the seat cushion frame of the adjustable car seat can be flipped and installed on a bracket mounted on the car floor through at least two connecting rods, and then driven by a drive mechanism to realize the forward flipping of the car seat, so that the seat cushion frame flips forward relative to the bracket, thereby expanding the trunk space of the car.

[0039] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] Reference Figures 1 to 9 , Figure 14 As shown, this utility model provides a car seat that can be adjusted forward, including: a bracket 1, a seat cushion frame 44, a drive mechanism 2, and a power assist mechanism 3.

[0043] Among them, bracket 1 is installed on the car floor 4.

[0044] A seat cushion is mounted on the seat frame 44. The seat frame 44 has a front end and a rear end opposite each other. A seat back is mounted on the rear end of the seat frame 44. The front end of the seat frame 44 is foldably mounted on the bracket 1.

[0045] Specifically, at least two connecting rods 111 are provided between the seat cushion frame 44 and the support 1. One end of each connecting rod 111 is fixedly connected to the seat cushion frame 44, and the other end of the connecting rod 111 is rotatably connected to the support 1 so that the seat cushion frame 44 can be flipped and connected to the support 1.

[0046] A locking mechanism 42 is rotatably mounted at the rear end of the seat cushion frame 44. The locking mechanism 42 is locked to the car floor 4. In this embodiment, the locking technology between the locking mechanism 42 and the locking rod on the car floor 4 is prior art, so the specific details of the locking mechanism will not be described here. A drive cable 43 is connected between the locking mechanism 42 and the winding reel 431. Pulling the drive cable 43 to flip the locking mechanism 42 unlocks the seat cushion frame 44.

[0047] The drive mechanism 2 is mounted on the support 1 and is used to drive the seat cushion frame 44 to flip forward relative to the support 1. The flip angle range of the seat cushion frame 44 can be 0° to 180°.

[0048] In this embodiment, the car seat that can be tilted forward is a three-row seat. If there is insufficient space in front, the seat cushion frame 44 can be tilted forward to about 80° to 90° and placed vertically; if there is sufficient space in front, the seat cushion frame can be tilted forward to about 180° and placed flat.

[0049] The front end of the adjustable car seat cushion frame 44 is mounted on the car floor 41 via at least two connecting rods 111. The support 1 is then driven by the drive mechanism 2 to achieve the forward flipping of the car seat, so that the cushion frame 44 flips forward relative to the support 1, thereby expanding the trunk space of the car.

[0050] See Figure 14 In some embodiments, a boss 41 is formed at the rear end of the vehicle floor 4. The front side of the boss 41 is used to mount the seat cushion frame 44 (i.e., the seat cushion frame of the three rows of seats), and the rear side of the boss is the trunk area for loading luggage. In this embodiment, "front," "front end," "front side," "rear," "rear end," and "rear side" refer to the front and rear of the vehicle, respectively. "Front" means towards the front of the vehicle, and "rear" means towards the parking space.

[0051] A seat frame 44 is provided above the front side of the boss 41. A bracket 1 is mounted on the front sidewall 411 of the boss 41. The front end of the seat frame 44 is rotatably mounted to the bracket 1 via a hinge shaft 13. A locking mechanism 42 is rotatably mounted on the rear end of the seat frame 44.

[0052] In this embodiment, the other end of each link 111 is rotatably connected to the bracket 1 via a hinge shaft 13, that is, the other end of the link 111 is fixedly connected to the hinge shaft 13.

[0053] The drive mechanism 2 includes a motor 21, the drive shaft of the motor 21 being fixedly connected (or driven connected) to the hinge shaft 13 to drive the hinge shaft 13 to rotate relative to the bracket 1.

[0054] In this embodiment, the assist mechanism 3 is disposed between the hinge shaft 13 and the bracket 1 to provide assistance for the flipping of the seat cushion frame 44. The assist mechanism 3 provides assistance to the seat cushion frame during the forward and / or backward flipping process, making the flipping of the seat cushion frame more stable.

[0055] Drive cable 43 is wound around reel 431. When drive cable 43 is pulled, it unlocks by rotating drive locking mechanism 42, allowing drive mechanism 2 to drive the third-row seats to flip forward. Seat cushion frame 44 flips forward 180° to the front of front sidewall 411. Figure 14 As shown, before the seat cushion frame 44 is flipped over, the seat back at the rear end of the seat cushion frame 44 is flipped forward and laid flat so that the car seat is in a folded state. Then, the seat cushion frame 44 is flipped forward and laid flat on the front side of the boss 41 with the hinge axis 13 at the front end as the axis of rotation, so that the seat cushion frame 44 is not higher than the top surface of the boss 41 (i.e., the trunk surface), thereby making the entire trunk without a protruding structure, so as to expand a larger trunk space.

[0056] Of course, if the space in front of the boss 41 is insufficient to accommodate the folded car seat, the second-row seat 45 can be moved forward to make room and the seat cushion frame 44 can be flipped forward to a vertical position.

[0057] This utility model discloses a forward-tilting adjustable car seat. By moving the tilting axis of the seat cushion frame 44 forward to the front sidewall 411 of the protrusion 41 on the car floor, the seat back of the seat cushion frame 44 is laid flat forward, and the seat cushion frame tilts forward 180°. This allows the entire car seat to be positioned in front of the protrusion 41, with the seat cushion frame 44 not exceeding the top surface of the protrusion 41. Consequently, the entire trunk has no protruding structure, thus expanding the trunk space. Furthermore, during the tilting process of the seat cushion frame 44, the auxiliary mechanism makes the tilting of the seat cushion frame 44 more stable, improving the customer experience.

[0058] As a preferred implementation method, combined with Figure 2 As shown, the support 1 includes two first side frames 11. The two first side frames are respectively disposed on the left and right sides of the seat cushion frame 44. The left and right sides of the front end of the seat cushion frame 44 are respectively rotatably mounted to the two first side frames 11 via hinge shafts 13. The drive mechanism 2 is drivenly connected to the hinge shaft 13 on one of the first side frames 11. The assist mechanism 3 is mounted on the other first side frame 11.

[0059] The front end of the seat frame 44 is mounted on the boss 41 via two first side brackets 11, which makes the structure of the seat frame 44 more stable and the flipping process smoother, avoiding deflection.

[0060] In a preferred embodiment, two connecting rods 111 are mounted on one side of the seat cushion frame 44. The two connecting rods 111 are respectively rotatably mounted on opposite sides of a first side frame 11 via hinge shafts 13. The drive mechanism 2 is driven by the hinge shaft 13 of one of the connecting rods 111 on one side of the seat cushion frame 44.

[0061] See Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, two connecting rods 111 are respectively installed on the left and right sides of the front end of the seat frame 44. The first side frame 11 includes a base plate, ear plates, and a reinforcing plate. The base plate is installed on the front side wall 411 of the boss 41. There are two ear plates. The ear plates are vertically mounted on the base plate. The two ear plates are arranged opposite to each other. The reinforcing plate is connected to the lower part of the two ear plates. Preferably, the ear plates are integrally formed with the base plate. The ear plates have through holes.

[0062] In this embodiment, there are two first side frames, one of which has a hinge shaft 13 connected to the drive mechanism, and the other has a hinge shaft 13 used to install the assist mechanism.

[0063] One end of the drive cable 43 is connected to a winding reel 431, and the other end is connected to a locking mechanism 42. The winding reel 431 is mounted on a first side frame 11. Specifically, the winding reel 431 is mounted on the base plate of the first side frame via a winding bracket 432, and is coaxially arranged with a through hole in an ear plate on the first side frame. The winding reel 431 is coaxially arranged with the hinge shaft 13 of another connecting rod 111 on one side of the seat cushion frame 44. The hinge shaft 13 is rotatably inserted through a through hole in another ear plate on the first side frame.

[0064] A connecting rod 111 on one side of the seat cushion frame 44 is hinged to a through hole in an ear plate on a first side frame 11 via a rotating screw. The rotating screw rotatably passes through a winding reel 431. Another connecting rod 111 on one side of the seat cushion frame 44 is hinged to a through hole in another ear plate on a first side frame 11 via a hinge shaft 13. The drive mechanism 2 includes a motor 21. The motor 21 is mounted on an ear plate of a first side frame 11, and the output end of the motor 21 is drive-connected to the hinge shaft 13.

[0065] In a preferred embodiment, the assist mechanism 3 is a leaf spring 31. One end of the leaf spring 31 is connected to the bracket 1, and the other end of the leaf spring is connected to the hinge shaft 13 to provide assistance for the seat frame 44 to flip forward or backward.

[0066] In a preferred embodiment, the assist mechanism 3 consists of a first leaf spring 31a and a second leaf spring 31b arranged in opposite directions on the hinge shaft 13. One end of the first and second leaf springs is connected to the bracket 1, and the other end is connected to the hinge shaft 13. The first and second leaf springs provide assistance for the seat cushion frame 44 to flip forward and backward, respectively.

[0067] See Figures 7 to 9 As shown, one end of the hinge shaft 13 is connected to a connecting rod 111 on the other side of the seat frame 44. The hinge shaft 13 is rotatably inserted into a through hole in an ear plate of another first side frame 11. A first leaf spring 31a and a second leaf spring 31b are sleeved on the hinge shaft 13. A limiting member 33 is connected between the two ear plates of the other first side frame 11. The two limiting members 33 are spaced apart along the circumferential direction of the through hole. One end of the first leaf spring 31a and the second leaf spring 31b are respectively connected to the hinge shaft 13, and the other end is respectively connected to the two limiting members 33.

[0068] When the seat frame 44 flips forward, the first leaf spring 31a provides positive auxiliary elastic force in the direction of rotation, while the second leaf spring 31b rotates and stores energy. Conversely, when the seat frame 44 flips backward, the second leaf spring 31b provides reverse auxiliary elastic force, while the first leaf spring 31a rotates and stores energy.

[0069] The double-sided leaf spring provides auxiliary spring force in both directions of rotation when the hinge shaft 13 rotates forward and backward. The double-sided leaf spring makes the flip adjustment easier and the rotation smoother.

[0070] The present invention relates to a car seat that can be tilted forward and adjusted. The seat cushion frame 44 is tilted by a motor driven by a drive mechanism, and rotational damping force is provided by a leaf spring or a bidirectional leaf spring, which makes the seat cushion frame tilting faster. In addition, due to its compact structure, it occupies little space, can achieve 180° tilting, and has a long service life.

[0071] Example 2

[0072] In this embodiment, apart from the removal of the assist mechanism in Embodiment 1 and the modification of the drive mechanism, the rest of the structure is basically the same as that in Embodiment 1, and will not be described again here.

[0073] The drive mechanism includes a motor 21 and a concentric angle adjuster 32. The concentric angle adjuster 32 is disposed between any one of the at least two links 111 and the bracket 1.

[0074] See Figure 10 and Figure 11 As shown, hinge arms 442 (i.e., connecting rods 111) are fixedly installed on opposite sides of the front end of the seat frame 44. The bracket 1 includes two second side frames 12. The two second side frames 12 are arranged opposite each other. One hinge arm 442 is rotatably mounted to one second side frame 12 via a hinge shaft 13. The hinge shaft 13 is fixedly connected to the hinge arm 442. The other hinge arm 442 is rotatably mounted to the other second side frame 12 via a concentric angle adjuster 32. The movable plate of the concentric angle adjuster 32 is connected to one hinge arm 442, and the fixed plate of the concentric angle adjuster 32 is connected to the other second side frame 12. The motor 21 is connected (or driven) to the concentric angle adjuster 32 via a synchronizing rod 131 to drive the hinge arm 442 to rotate relative to the bracket 1.

[0075] In this embodiment, a single concentric angle adjuster is used, which has a simple structure, is easy to assemble, and reduces costs. At the same time, the concentric angle adjuster 32 makes the seat frame rotate smoothly, without vibration during the flipping process, with good visual effect and better customer experience.

[0076] Example 3

[0077] In this embodiment, apart from the removal of the assist mechanism in Embodiment 1 and the modification of the drive mechanism, the rest of the structure is basically the same as that in Embodiment 1, and will not be described again here.

[0078] For details, please refer to Figure 12 and Figure 13As shown, hinge arms 442 (i.e., connecting rods 111) are fixedly installed on opposite sides of the front end of the seat cushion frame 44. The bracket 1 includes two second side frames 12. The two second side frames 12 are arranged opposite to each other. The drive mechanism 2 includes a motor 21 and two adjusters 34. Each adjuster includes a fixed plate and a movable plate that rotates relative to the fixed plate. The fixed plate of each adjuster 34 is connected to the second side frame 12 on the corresponding side, and the movable plate is connected to the hinge arm 442 on the corresponding side, so as to realize the rotation of the hinge arm 442 relative to the second side frame 12. The two adjusters 34 are connected by a synchronizing rod 131, which passes through the motor 21 so that the motor 21 drives the two adjusters 34 through the synchronizing rod 131, thereby driving the seat cushion frame 44 to rotate relative to the bracket 1.

[0079] In this embodiment, the two angle adjusters can be either concentric or eccentric. Using two symmetrically arranged angle adjusters provides higher locking strength, allowing the heavy seat frame to rotate smoothly and meeting the locking strength requirements during a collision.

[0080] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
