Description

Car seat frame and car seat This invention is based on CN application number CN202422641857.3, filed on October 30, 2024, and claims priority to it. The disclosure of the CN application is incorporated herein by reference in its entirety. Technical Field

[0001] This disclosure relates to the field of automotive seat technology, and more specifically to an automotive seat frame and an automotive seat. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for driving and riding comfort, the design and functional optimization of car seats have become a key focus for automakers and parts suppliers. Traditional car seat design mainly focuses on providing basic seating support and safety. Among them, the folding function, as an important manifestation of space utilization and convenience, has been widely used in various models, allowing users to flexibly adjust the interior space layout according to actual needs, increase storage space, or facilitate passenger entry and exit.

[0003] However, the height of existing car seats is fixed and cannot be adjusted, making it difficult to meet the needs of drivers and passengers of different heights and body types for optimal seating posture and visibility. Summary of the Invention

[0004] The purpose of this disclosure is to provide a car seat frame and a car seat that can be folded and height-adjusted to meet the seating needs of occupants of different heights.

[0005] To achieve the above objectives, this disclosure provides an automotive seat frame, including a base, a seat cushion frame, and a backrest frame. The seat cushion frame includes a base assembly and a seat pan assembly, and the backrest frame is rotatably connected to the base assembly. A first end of the base assembly is rotatably connected to a first end of the base, and a second end of the base assembly is rotatably connected to a second end of the base. A first end of the seat pan assembly is slidably and rotatably connected to a first end of the base assembly, and a second end of the seat pan assembly is rotatably connected to a second end of the base assembly. The seat cushion frame is folded by the movement of the seat pan assembly relative to the base assembly, and the height of the seat cushion frame and the backrest frame is adjusted by the movement of the base assembly relative to the base.

[0006] In this disclosure, the folding of the car seat frame is achieved by the movement of the seat cushion assembly relative to the base assembly, and the height adjustment is achieved by the rotation of the base assembly relative to the base, thereby meeting the seating needs of different occupants. In this disclosure, "the folding of the seat cushion frame" refers to the folded position of the seat cushion frame, in which the backrest frame rotates relative to the base assembly, thereby folding the car seat frame. In conventional designs, without a separate seat cushion assembly, the rotation angle of the backrest frame is limited by the fixed height of the seat cushion frame with a fixed seat cushion, making the folded backrest frame appear uneven. To eliminate or reduce the influence of this fixed height, the backrest frame and seat cushion frame need to be separated, and the seat cushion frame should be moved forward as a whole during folding to create some height space for the backrest frame to fold more "flat." However, this separation design is structurally complex. In this disclosure, by means of a separately configured seat basin assembly that can move relative to the base assembly, more height space can be created by folding the backrest frame through the separately moving seat basin assembly without separating the backrest frame and the seat cushion frame.

[0050] The preferred embodiments of this disclosure are given below with reference to the accompanying drawings and described in detail.

[0051] In this disclosure, the X direction is a direction in the vehicle coordinate system that is parallel to the horizontal plane and points towards the front or rear of the vehicle; the Y direction is a direction in the vehicle coordinate system that is parallel to the horizontal plane and points towards the driver's or passenger's side; and the Z direction is a direction that is perpendicular to the horizontal plane and points towards the roof or bottom of the vehicle.

[0052] As shown in Figures 1, 2, and 3, this embodiment of the invention provides an automobile seat frame, which includes a base 100, a seat cushion frame 200, and a backrest frame 300. The seat cushion frame 200 includes a base assembly 210 and a seat basin assembly 220. The backrest frame 300 is rotatably connected to the base assembly 210 and can rotate relative to the base assembly 210. For ease of description, the end of the base 100, base assembly 210, and seat basin assembly 220 closest to the backrest frame 300 is referred to as the first end, and the end of the base 100, base assembly 210, and seat basin assembly 220 furthest from the backrest frame 300 is referred to as the second end. That is, the first end and the second end refer to the two ends along the X-direction. The first end of the base assembly 210 rotates with the first end of the base 100. The seat frame is rotatably connected to the second end of the base assembly 210 and the second end of the base 100. The first end of the seat basin assembly 220 is slidably and rotatably connected to the first end of the base assembly 210, and the second end of the seat basin assembly 220 is rotatably connected to the second end of the base assembly 210. The angle between the backrest frame 300 and the seat cushion frame 200 can be adjusted by rotating the backrest frame 300 relative to the seat cushion frame 200. The seat cushion frame 200 can be folded by rotating and sliding the seat basin assembly 220 relative to the base assembly 210. The height of the base assembly 210 along the Z-axis can be adjusted by rotating the base assembly 210 relative to the base 100, thus adjusting the overall height of the seat cushion frame 200 and the backrest frame 300. Therefore, the car seat frame disclosed herein can both fold and be height-adjustable, thereby adapting to the seating needs of occupants of different heights.

[0053] In some embodiments, the car seat frame may further include a first drive mechanism 400 and a second drive mechanism 500. The first drive mechanism 400 is used to drive the base assembly 210 to rotate relative to the base 100, thereby achieving height adjustment. The second drive mechanism 500 is connected to the base assembly 210 and the seat basin assembly 220 respectively, and is used to drive the seat basin assembly 220 to rotate and slide relative to the base assembly 210, thereby achieving folding of the seat cushion frame 200.

[0054] In some embodiments, the car seat frame may further include a sliding mechanism 600, which is disposed on the vehicle body frame and the base 100 is disposed on the sliding mechanism 600. The sliding mechanism 600 is used to slide the base 100 in the X direction, thereby causing the seat cushion frame 200 and the backrest frame 300 to move as a whole in the X direction.

[0055] As shown in Figure 4, in some embodiments, the base 100 includes two first fixing seats 110a and 110b opposite each other along the Y direction and two second fixing seats 120a and 120b opposite each other along the Y direction. The first fixing seats 110a and 120a are located on the same side, and the first fixing seats 110b and 120b are located on the same side. For ease of description, the side where the first fixing seats 110a and 120a are located is referred to as the first side, and the side where the second fixing seats 110b and 120b are located is referred to as the second side. The first fixing seats 110a and 120a are spaced apart along the X direction on the first side, and the first fixing seats 110b and 120b are spaced apart along the X direction on the second side. The first end of the base assembly 210 is hinged to the two first fixing seats 110a and 110b respectively, and the second end of the base assembly 210 is hinged to the two second fixing seats 120a and 120b respectively. Of course, in addition to the arrangement of the two first fixing seats 110a and 110b and the two second fixing seats 120a and 120b, it is also conceivable that there are only two fixing seats opposite each other along the Y direction, which cover the arrangement area of ​​the first fixing seats 110a and 110b and the second fixing seats 120a and 120b.

[0056] In some embodiments, the sliding mechanism 600 may include two slide rails 610a and 610b opposite each other along the Y direction. Slide rail 610a is located on the first side and slide rail 610b is located on the second side. Both slide rails 610a and 610b extend along the X direction. A slider 620a is slidably disposed in slide rail 610a and slider 620b is slidably disposed in slide rail 610b. A first fixed seat 110a and a second fixed seat 120a are fixed on slider 610a, and a first fixed seat 110b and a second fixed seat 120b are fixed on slider 620b. In this way, the first fixed seat and the second fixed seat can slide along the slide rail with the slider. The slide rail can be fixed on the vehicle frame, so that the base 100 can slide relative to the vehicle frame along the X direction. The sliding mechanism 600 may further include a third drive mechanism 630, which is connected to the two sliders 620a and 620b respectively, and is used to drive the two sliders 620a and 620b to slide in their respective slide rails 610a and 610b, thereby driving the base 100 to slide relative to the vehicle frame. The third drive mechanism 630 can be any suitable drive device, such as a ball screw mechanism, as long as it can drive the two sliders 620a and 620b to slide synchronously along the X direction.

[0057] In some embodiments, the base assembly 210 may include two first side plates 211a and 211b that are opposite each other along the Y direction and both extend along the X direction, with the first side plate 211a located on a first side and the second side plate 211b located on a second side; the base assembly 210 may also include a first connecting pipe 213 and a second connecting pipe 214, the first connecting pipe 213 extending along the Y direction and having its two ends hinged to the first end of the first side plate 211a and the first end of the first side plate 211b respectively, and the second connecting pipe 214 extending along the Y direction and having its two ends fixedly connected (e.g., welded together) to the second end of the first side plate 211a and the second end of the first side plate 211b respectively; the base assembly 210 may also include two first connecting rods 215a and 215b and two second connecting rods 216a and 216b, the first connecting rods 215a and 216a being located on the first side and the second connecting rod 211b being on the second side; On one side, the first connecting rod 215b and the second connecting rod 216b are located on the second side. One end of the first connecting rod 215a is fixedly connected to the first connecting pipe 213, and the other end is hinged to the first fixed seat 110a. One end of the second connecting rod 215b is fixedly connected to the first connecting pipe 213, and the other end is hinged to the first fixed seat 110b (since the two ends of the first connecting pipe 213 are rotatably connected to the two first side plates 211a and 211b respectively, this is equivalent to the two first connecting rods 215a and 215b being hinged to the two first side plates 211a and 211b respectively). One end of the second connecting rod 216a is hinged to the second end of the first side plate 211a, and the other end is hinged to the second fixed seat 120a. One end of the second connecting rod 216b is hinged to the second end of the first side plate 211b, and the other end is hinged to the second fixed seat 120b. Thus, the base assembly 210 can be formed as a four-bar linkage. The first link, the first side plate, and the second link are equivalent to three links that are hinged in sequence in the four-bar linkage. When the four-bar linkage rotates, its height will change continuously. Therefore, the height of the base assembly 210 can be adjusted by rotating the four-bar linkage.

[0058] In some embodiments, the two ends of the second connecting pipe 214 are welded to the two first side plates 211a and 211b respectively via two welding brackets 217a and 217b. That is, one end of the second connecting pipe 214 is welded to the welding bracket 217a, the welding bracket 217a is welded to the first side plate 211a, and the other end of the second connecting pipe 214 is welded to the welding bracket 217b, the welding bracket 217b is welded to the first side plate 211b.

[0059] In some embodiments, one end of the first drive mechanism 400 is hinged to the first link 215a or the first link 215b, and the other end is hinged to the second connecting tube 214. The first drive mechanism 400 may include a first motor 410, a first reducer 420, a first lead screw 430, and a first nut 440. The first motor 410 is connected to the first reducer 420, the first reducer 420 is connected to the first lead screw 430, and the first nut 440 is threadedly connected to the first lead screw 430. The first drive mechanism 400 is formed as a ball screw structure. When the first motor 410 is running, it can drive the first lead screw 430 to rotate. The rotation of the first lead screw 430 will drive the first nut 440 to slide along the first lead screw 430, thereby achieving the telescopic effect. The first motor 410 can be hinged to the second connecting pipe 214, and the end of the first nut 440 away from the first motor 410 is hinged to the first connecting rod 215a or the first connecting rod 215b. In this way, when the first drive mechanism 400 telescopic, it can drive the base assembly 210, a four-bar linkage, to rotate, thereby achieving height adjustment. The second connecting pipe 214 may be provided with a first motor bracket 218a, and the first motor 410 may be hinged to the first motor bracket 218a.

[0060] In some embodiments, the sitz bath assembly 220 includes two second side plates 221a and 221b opposite each other along the Y direction and two third connecting rods 222a and 222b opposite each other along the Y direction. The second side plates 221a and the third connecting rods 222a are located on a first side, and the second side plates 221b and the third connecting rods 222b are located on a second side. The first end of the second side plate 221a is slidably and rotatably connected to the first side plate 211a, and the first end of the second side plate 221b is slidably and rotatably connected to the first side plate 211b. The second end is hinged to the first end of the third link 222a, the second end of the second side plate 221b is hinged to the first end of the third link 222b, the second end of the third link 222a is hinged to the second end of the first side plate 211a, and the second end of the third link 222b is hinged to the second end of the first side plate 211b. Thus, the seat assembly 220 forms a three-bar linkage mechanism. By sliding and rotating the first end of the second side plate relative to the first side plate, the seat assembly 220, or the seat frame 200, can be folded.

[0061] In this disclosure, in addition to the above-described arrangement, for the first connecting rods 215a and 215b, it is also conceivable that both ends of the first connecting tube 213 are fixedly connected to the corresponding first ends of the two first side plates 215a and 215b, and one end of each first connecting rod 215a and 215b is hinged to the first connecting tube 213. Alternatively, it is also conceivable that one end of the corresponding first connecting rod 215a and 215b is hinged to the corresponding first side plate 211a and 211b on its side, and both ends of the first connecting tube 213 can be fixedly connected to the first ends of the two first side plates 211a and 211b, respectively. For the second connecting rods 216a and 216b, in addition to the above-described arrangement, when the first motor bracket 218a or other components that would restrict the rotational movement of the second connecting rod tube 214 are not arranged on the second connecting rod tube 214, it is also conceivable that both ends of the second connecting tube 214 are hinged to the second ends of the two first side plates 211a and 211b respectively, and one end of the corresponding second connecting rods 216a and 216b is fixedly connected to the second connecting tube 214. Alternatively, it is also conceivable that both ends of the second connecting tube 214 are fixedly connected to the second ends of the two first side plates 211a and 211b respectively, and one end of the corresponding second connecting rods 216a and 216b is hinged to the second connecting tube 214.

[0062] One end of the second connecting rods 216a and 216b is hinged to the second end of the first side plates 211a and 211b on the same side, wherein the two ends of the second connecting tube 214 are fixedly connected to the second ends of the two first side plates 211a and 211b respectively.

[0063] In some embodiments, the basin assembly 220 may further include a third connecting pipe 223 and a fourth connecting pipe 224. The third connecting pipe 223 extends along the Y direction and its two ends are fixedly connected (e.g., welded) to the first ends of the two second side plates 221a and 221b, respectively. The fourth connecting pipe 224 extends along the Y direction and its two ends are fixedly connected (e.g., welded) to the two third connecting rods 222a and 222b, respectively. The basin assembly 220 may further include a fifth connecting pipe 225 and a basin 226. The fifth connecting pipe 225 extends along the Y direction and its two ends are fixedly connected (e.g., welded) to the two second side plates 221a and 221b, respectively. The basin 226 is fixed to the fifth connecting pipe 225.

[0064] As shown in Figures 8A and 8B, in some embodiments, one end of the second drive mechanism 500 is hinged to the first side plate 211a or 211b, and the other end is hinged to the fourth connecting pipe 224 to drive the seat assembly 220 to slide and rotate relative to the base assembly 210, thereby enabling the seat assembly 220 to switch between the designed state and the folded state. The second drive mechanism 500 may include a second motor 510, a second reducer 520, a second lead screw 530, and a second nut 540. The second motor 510 is connected to the second reducer 520, the second reducer 520 is connected to the second lead screw 530, and the second nut 540 is threadedly connected to the second lead screw 530. The second drive mechanism 500 is formed as a ball screw structure. When the second motor 510 operates, it can drive the second lead screw 530 to rotate. The rotation of the second lead screw 530 causes the second nut 540 to slide along the second lead screw 530, thereby achieving the telescopic effect. The end of the second nut 540 away from the second motor 510 can be hinged to the first side plate 211a or the first side plate 211b, and the second motor 510 can be hinged to the fourth connecting pipe 224. A hinge bracket 218b can be fixed on the first side plate 211a or the first side plate 211b, and a second motor bracket 227 can be fixed on the fourth connecting pipe 224. The end of the second nut 540 away from the second motor 510 is hinged to the second motor bracket 227.

[0065] To avoid interference, the first drive mechanism 400 and the second drive mechanism 500 can be located on different sides in the Y direction and connected to the first side plate on their respective sides. For example, the first drive mechanism 400 is located on the first side and the second drive mechanism 500 is located on the second side.

[0066] In some embodiments, the first end of the second side plate can be slidably and rotatably connected to the first side plate via a sliding element 230. The sliding element 230 is disposed at the first end of the second side plate in the designed state. A sliding groove plate 219a is fixed on the first side plate 211a, and a sliding groove plate 219b is fixed on the first side plate 211b. The sliding groove plate 219a has a groove 2191a extending in the X direction, and the sliding groove plate 219b has a groove 2191b extending in the X direction. The sliding element 230 is slidably disposed in the grooves 2191a and 2191b, thereby allowing the first end of the second side plate to be slidably and rotatably connected to the first side plate via the sliding element 230. As shown in Figures 5, 6, and 7, the sliding element 230 may include a stepped bolt 231, a bushing 232, a washer 233, and a fastening nut (not shown in the figures). The bushing 232 may be configured such that its length extending along the groove direction is greater than its length extending perpendicular to the groove direction, for example, an elliptical shape, to prevent the bushing 232 from deflecting during sliding. Taking the first side as an example, the bushing 232 is fitted on the stepped shaft 2311 of the stepped bolt 231 and slidably disposed in the groove 219a. The washer 233 is also fitted on the stepped shaft 2311 of the stepped bolt 231 and cooperates with the bolt head 2312 of the stepped bolt 231 to axially limit the bushing 232. The stepped shaft 2311 passes through the second side plate 221a. The fastening nut is screwed on the stepped bolt 231 and cooperates with the second side plate 221a to axially limit the washer 233. The end face of the washer 233 slides and rubs against the groove plate. On the second side, the connection relationship between the sliding element 230, the slide plate 219b, and the second side plate 221b is the same as that on the first side, and will not be described again here. The first side plate 211b is reused through itself and the slide groove 2191a on the first side plate 211b. The first side plate 211b itself can be used as part of the four-bar linkage of the base assembly 210, and can also be used as part of the moving base of the seat assembly 220.

[0067] In some embodiments, as shown in Figures 9A and 9B, the second drive mechanism 500 may also be hinged at one end to the second connecting tube 214 and at the other end to the sliding element 230. Alternatively, as shown in Figures 10A and 10B, the second drive mechanism 500 may also be hinged at one end to the fifth connecting tube 225 and at the other end to the first side plate 211a or the first side plate 211b.

[0068] Referring again to Figure 4, the backrest frame 300 may include two backrest side panels 310a and 310b, an upper backrest curved tube 330, a lower backrest horizontal plate 330, and two angle adjusters 340a and 340b. The two ends of the upper backrest curved tube 320 are fixedly connected (e.g., welded) to the upper ends of the two backrest side panels 310a and 310b, respectively. The two ends of the lower backrest horizontal plate 330 are fixedly connected (e.g., welded) to the lower ends of the two backrest side panels 310a and 310b, respectively. The lower end of the backrest side panel 310a also... The backrest side plate 310b is rotatably connected to the first side plate 211a via an angle adjuster 340a, and the lower end of the backrest side plate 310b is also rotatably connected to the first side plate 211b via an angle adjuster 340b. The two angle adjusters 340a and 340b are connected via a synchronizing rod 350, which is connected to a third motor 360. The third motor 360 drives the two angle adjusters 340a and 340b to rotate, thereby driving the backrest frame 300 to rotate relative to the base 100 and to hover at any position.

[0069] In some embodiments, the backrest side panel 310a is rotatably connected to the lower backrest connecting plate 370a via an angle adjuster 340a, the backrest side panel 310b is rotatably connected to the lower backrest connecting plate 370b via an angle adjuster 340b, the lower backrest connecting plate 370a is fixedly connected to the first side panel 211a (e.g., by welding), and the lower backrest connecting plate 370b is fixedly connected to the first side panel 211b.

[0070] In some embodiments, two headrest mounting tubes 380 are provided at intervals on the backrest upper curved tube 320 for mounting headrests.

[0071] The car seat frame of this disclosure embodiment has multiple different postures and can switch between them, such as the lowest height posture shown in Figure 11, the highest height posture shown in Figure 12, the folded posture shown in Figure 13, and the rear-folding bed posture shown in Figure 14. The car seat frame can switch between different postures by one or more of the following: the movement of the base assembly 210 relative to the base 100, the movement of the seat basin assembly 220 relative to the base assembly 210, the movement of the backrest frame 300 relative to the base assembly 210, and the movement of the base 100 relative to the car body frame. For example, by driving the base assembly 210 to rotate relative to the base 100 through the first drive mechanism 400, the overall height of the car seat frame can be adjusted, thereby switching between the lowest height posture and the highest height posture. The second drive mechanism 400 can drive the seat basin assembly 220 to rotate and slide relative to the base assembly 210, causing the seat basin assembly 220 to move forward along the X direction. Simultaneously, the third motor 360 can drive the backrest frame 300 to rotate relative to the base assembly 210, bringing it closer to the base assembly 210, thereby allowing the car seat frame to... When folded, the base 100 can move forward along the X-direction via the third drive mechanism, thereby freeing up space behind the seat. The backrest frame 300 can be rotated relative to the base assembly 210 via the third motor 360, and the angle of the backrest frame 300 can be adjusted to accommodate different occupants. When the backrest frame 300 rotates away from the base assembly 210 to a near-horizontal position, the car seat frame is in a reclining bed posture as shown in Figure 13. At this time, the car seat frame can be used as a bed, and occupants can lie on it. In this disclosure, the seat cushion assembly 220 can rotate and slide independently relative to the base assembly 210, allowing the seat cushion assembly 220 to move forward and downward. This forward and downward movement of the seat cushion assembly 220 frees up height space, resulting in a smaller overall vertical height of the seat cushion frame 200 and allowing the backrest frame 300 to fold flatter than in conventional designs.

[0072] It is understandable that, in addition to the postures shown in Figures 11-14, the car seat frame can achieve any other suitable posture through the movement of its various components.

[0073] As mentioned earlier, the first drive mechanism 400 can adjust the height of the car seat frame by extending and retracting. When the first drive mechanism 400 extends (i.e., the length between its two ends increases), the height of the car seat frame will increase. When the first drive mechanism 400 retracts (i.e., the length between its two ends decreases), the height of the car seat frame will decrease. As shown in Figure 15, when the car seat frame is in its lowest height position, the length between the two ends of the first drive mechanism 400 is the shortest. As shown in Figure 16, when the car seat frame is in its highest height position, the length between the two ends of the first drive mechanism 400 is the longest.

[0074] As shown in Figures 17 and 18, in some embodiments, the car seat frame may further include a lifting mechanism 700. The lifting mechanism 700 is fixed to the vehicle body frame, and a sliding mechanism 600 is disposed on the lifting mechanism 700. The lifting mechanism 700 is used to raise or lower the sliding mechanism 600, base 100, base assembly 210, seat assembly 220, and backrest frame 300 along the Z-direction, thereby adjusting the height of the car seat frame. That is to say, this embodiment adds a lifting mechanism 700 to the bottom of the car seat frame in Figure 1, so that the overall height of the car seat frame can be further adjusted through the lifting mechanism 700.

[0075] The lifting mechanism 700 can be any suitable lifting device, such as a cylinder lifting device, a crossarm lifting device, a ball screw lifting device, etc. The lifting mechanism 700 can be driven electrically, hydraulically, or by any other suitable means.

[0076] This disclosure also provides an automobile seat, which includes an automobile seat frame as described in the above embodiments.

[0077] The car seat and car seat frame of this disclosure embodiment can be folded by the movement of the seat assembly 220 relative to the base assembly 210, and the height can be adjusted by the rotation of the base assembly 210 relative to the base 100, thereby meeting the seating needs of different occupants; the height can be further adjusted by the lifting mechanism 700, making its adjustment range wider and its adaptability wider.
