[0046] The preferred embodiments of this disclosure are given below with reference to the accompanying drawings and described in detail.

[0047] As shown in Figures 1A, 1B, 1C, and 2, this embodiment of the present disclosure provides an automobile seat frame, including a base 100, a seat cushion frame 200, a backrest frame 300, a headrest frame 400, and a support panel assembly 500. The backrest frame 300 is rotatably connected to the base 100 and can rotate relative to the base 100. One end of the seat cushion frame 200 is hinged to the backrest frame 300, and the other end is slidably hinged to the base 100, so that one end of the seat cushion frame 200 can rotate relative to the backrest frame 300, and the other end can simultaneously rotate and slide relative to the base 100. The headrest frame 400 is rotatably connected to the backrest frame 300 and can rotate relative to the backrest frame 300. The support panel assembly 500 is rotatably connected to the backrest frame 300 and can rotate relative to the backrest frame 300. When the backrest frame 300 rotates relative to the base 100, it will cause the seat cushion frame 200 to move relative to both the base 100 and the backrest frame 300. The rotation of the backrest frame 300 relative to the base 100 can adjust the angles between the backrest frame 300 and the base 100, between the backrest frame 300 and the seat cushion frame 200, and between the seat cushion frame 200 and the base 100. The rotation of the headrest frame 400 relative to the backrest frame 300 can adjust the angles between the headrest frame 400 and the backrest frame 300. The rotation of the support panel assembly 500 relative to the backrest frame 300 can adjust the angles between the support panel assembly 500 and the backrest frame 300. The car seat frame has a designed state, a semi-open state, and a fully open state. By rotating the backrest frame 300 relative to the base 100, the headrest frame 400 relative to the backrest frame 300, and the support panel assembly 500 relative to the backrest frame 300, the car seat frame can be switched between the designed state, the semi-open state, and the fully open state, thus enabling the car seat to have multiple uses and meet user needs.

[0048] As shown in Figure 1A, when the car seat frame is in the design state, the angle between the backrest frame 300 and the horizontal plane (i.e., the XY plane) is α1, the angle between the seat cushion frame 200 and the horizontal plane is β1, the angle between the headrest frame 400 and the backrest frame 300 is γ1, and the support panel assembly 500 is basically parallel to the backrest frame 300 and hidden behind the backrest frame 300. As shown in Figure 1B, when the car seat frame is in a semi-expanded state, compared to the designed state, the backrest frame 300 rotates at a certain angle relative to the base 100 away from the seat cushion frame 200, and the seat cushion frame 200 also rotates relative to the backrest frame 300. The support panel assembly 500 does not move relative to the backrest frame 300. At this time, the angle between the backrest frame 300 and the horizontal plane is α2 (α2 < α1), the angle between the seat cushion frame 200 and the horizontal plane is β2 (β2 < β1), and the angle between the headrest frame 400 and the backrest frame 300 is γ2 (γ2 = γ1). The support panel assembly 500 is basically parallel to the backrest frame 300 and is hidden behind the backrest frame 300. In the semi-expanded state, the car seat frame forms a large sofa, making it more comfortable for passengers to sit in. As shown in Figure 1C, when the car seat frame is in the fully extended state, compared to the semi-extended state, the backrest frame 300 continues to rotate away from the seat cushion frame 200 relative to the base 100 by a certain angle, the headrest frame 400 also rotates relative to the backrest frame 300, and the support panel assembly 500 rotates about 180 degrees relative to the backrest frame 300. At this time, the seat cushion frame 200, backrest frame 300, headrest frame 400, and support panel assembly 500 are basically flush and all located in the horizontal plane, so that the car seat frame is fully extended to form a bed (up to two meters in length), providing a complete rest and relaxation environment for the occupants.

[0049] As shown in Figures 3A, 3B, and 3C, in some embodiments, the backrest frame 300 may include a backrest main frame 310, two backrest side plates 320a and 320b, and a first driving device 330. The two backrest side plates 320a and 320b are arranged opposite each other along the Y direction and are respectively fixed on both sides of the backrest main frame 310. The two backrest side plates 320a and 320b are rotatably connected to the base 100. The first driving device 330 is installed on the backrest main frame 310 and is connected to the two backrest side plates 320a and 320b and the base 100 respectively, for driving the two backrest side plates 320a and 320b to rotate relative to the base 100, that is, driving the backrest frame 300 to rotate relative to the base 100. Specifically, two hinge brackets 340a and 340b can be fixed on the base 100, which correspond one-to-one with the two backrest side plates 320a and 320b. The backrest side plate 320a is hinged to the hinge bracket 340a, and the backrest side plate 320b is hinged to the hinge bracket 340b, thereby making the backrest side plate 320 rotatably connected to the base 100.

[0050] In some embodiments, the first drive device 330 includes two first motors 331a and 331b and two first angle adjusters 332a and 332b. The first motors 331a and the first angle adjusters 332a are located on one side of the backrest frame 300 in the Y direction, and the first motors 331b and the first angle adjusters 332b are located on the other side of the backrest frame 300 in the Y direction. The first motors 331a are connected to the first angle adjusters 332a, and the first angle adjusters 332a are respectively connected to the backrest side panel 320a and the hinge frame 340a, so that the backrest side panel 320a and the hinge frame 340a are connected to each other. Hinged by the first angle adjuster 332a, the first motor 331a can drive the first angle adjuster 332a to rotate, thereby causing the backrest side panel 320a to rotate relative to the hinge frame 340a; the first motor 331b is connected to the first angle adjuster 332b, and the first angle adjuster 332b is connected to the backrest side panel 320b and the hinge frame 340b respectively, so that the backrest side panel 320b and the hinge frame 340b are hinged by the first angle adjuster 332b, and the first motor 331b can drive the first angle adjuster 332b to rotate, thereby causing the backrest side panel 320b to rotate relative to the hinge frame 340b.

[0051] In some embodiments, the first driving device 330 may further include two second angle adjusters 333a and 333b and two reinforcing plates 334a and 334b. The second angle adjusters 333a and the reinforcing plates 334a are located on one side of the backrest frame 300 in the Y direction, and the second angle adjusters 333b and the reinforcing plates 334b ​​are located on the other side of the backrest frame 300 in the Y direction. The second angle adjusters 333a are connected to the hinge frame 340a and the reinforcing plates 334a respectively, so that the reinforcing plates 334a are rotatably connected to the hinge frame 340a and can rotate relative to the hinge frame 340a. The second angle adjusters 333b are connected to the hinge frame 340b and the reinforcing plates 334b ​​respectively, so that the reinforcing plates 334b ​​are rotatably connected to the hinge frame 340b and can rotate relative to the hinge frame 340b. With the two second angle adjusters and the two reinforcing plates, the first driving device 330 can drive the backrest frame 300 to rotate more stably.

[0052] The angle adjuster includes a fixed part and a rotating part. The rotating part can rotate relative to the fixed part. In use, the rotating part is usually fixed to one of the two parts, and then the fixed part is fixed to the other of the two parts, so that the two parts are rotatably connected. For example, the rotating part of the first angle adjuster can be connected to the corresponding first motor and the backrest side panel, and the fixed part of the first angle adjuster can be fixed to the corresponding hinge frame. In this way, when the first motor rotates, it can drive the rotating part to rotate relative to the fixed part, thereby causing the backrest side panel to rotate relative to the hinge frame. The structure and working principle of the angle adjuster are known in the art and will not be described in detail in this disclosure.

[0053] As shown in Figure 4, in some embodiments, the seat cushion frame 200 may include a main seat cushion frame 210 and at least two seat cushion side plates 220a and 220b. The two seat cushion side plates 220a and 220b are respectively fixed on both sides of the main seat cushion frame 210 in the Y direction. One end of the seat cushion side plate 220a is hinged to one end of the backrest side plate 320a (e.g., pivot connection), and one end of the seat cushion side plate 220b is hinged to one end of the backrest side plate 320b (e.g., pivot connection). The seat cushion side plates 220a and 220b are also slidably hinged to the base 100, so that one end of the seat cushion frame 200 is hinged to the backrest frame 300 and the other end is slidably hinged to the base 100.

[0054] As shown in Figure 5, the base 100 may include a base main frame 110 and two base side plates 120a and 120b. The two base side plates 120a and 120b are respectively fixed on both sides of the base main frame 110 in the Y direction. The seat side plate 220a is slidably hinged to the base side plate 120a, and the seat side plate 220b is slidably hinged to the base side plate 120b. Specifically, the base side plate 120a may be provided with a sliding groove 121a, the base side plate 120b may be provided with a sliding groove 121b, the seat side plate 220a may be provided with a protruding pin 221a, and the seat side plate 220b may be provided with a protruding pin 221b. The protruding pin 221a is inserted into the sliding groove 121a and can slide and rotate within the sliding groove 121a, thereby slidably hinged to the seat side plate 220a and the base side plate 120a. The protruding pin 221b is inserted into the sliding groove 121b and can slide and rotate within the sliding groove 121b, thereby slidably hinged to the seat side plate 220b and the base side plate 120b. It can be understood that the positions of the sliding groove and the protruding pin can be interchanged, that is, a protruding pin can be provided on each base side plate 120a, 120b, and a corresponding sliding groove matching the protruding pin can be provided on each seat side plate 220a, 220b.

[0055] In some embodiments, the main frame 110 of the base may include two base supports 110a and 110b, and the base 100 may also include two base side plates 120c and 120d. The base side plates 120a and 120c are respectively fixed to the Y-direction sides of the base support 110a, and the base side plates 120b and 120d are respectively fixed to the Y-direction sides of the base support 110b. The base side plates 120c and 120d are fixed together by a first connecting pipe 130, so that the base 100 forms an integral frame structure. Specifically, one end of the base side plates 120a and 120c is fixedly connected to the base support 110a, and the other end of the base side plates 120a and 120c is connected by a second connecting pipe 140a to increase their strength; one end of the base side plates 120b and 120d is fixedly connected to the base support 110b, and the other end of the base side plates 120b and 120d is connected by a second connecting pipe 140b to increase their strength.

[0056] Referring again to Figure 4, the seat cushion frame 200 may further include two seat cushion side plates 220c and 220d, both of which are fixed to the seat cushion main frame 210. The two seat cushion side plates 220c and 220d are located between the two seat cushion side plates 220a and 220b. A protruding pin 221c is provided on the seat cushion side plate 220c, and a protruding pin 221d is provided on the seat cushion side plate 220d. A sliding groove 121c is provided on the base side plate 120c. The seat frame 200 is provided with a slide groove 121d, and a protruding pin 221c is inserted into the slide groove 121c and can slide and rotate in the slide groove 121c so that the seat side plate 220c and the base side plate 120c can be slidably hinged. The protruding pin 221d is inserted into the slide groove 121d and can slide and rotate in the slide groove 121d so that the seat side plate 220d and the base side plate 120d can be slidably hinged. In this way, the seat frame 200 can be more stable when moving relative to the base 100.

[0057] As shown in Figure 2, the headrest frame 400 may include a headrest rotating assembly 410 and a headrest support frame 420. The headrest rotating assembly 410 is rotatably connected to the backrest frame 300 and can rotate relative to the backrest frame 300. The headrest support frame 420 is fixed on the headrest rotating assembly 410 so that it can rotate relative to the backrest frame 300 together with the headrest rotating assembly.

[0058] As shown in Figures 6A, 6B, and 6C, the headrest rotation assembly 410 may include a headrest crossbeam 411 and a second drive device. The headrest crossbeam 411 is rotatably connected to the backrest frame 300, and the second drive device is connected to the headrest crossbeam 411 to drive the headrest crossbeam 411 to rotate relative to the backrest frame 300. Specifically, the second drive device includes two second motors 412a and 412b, two third angle adjusters 413a and 413b, and two headrest fixing brackets 414a and 414b. The second motors 412a, third angle adjusters 413a, and headrest fixing brackets 414a are located at one end of the headrest crossbeam 411, and the second motors 412b, third angle adjusters 413b, and headrest fixing brackets 414b are located at the other end of the headrest crossbeam 411. The second motors 412a are connected to the third angle adjusters 413a (e.g., via planetary rods 415a), and the third angle adjusters 413a are respectively connected to the headrest crossbeam 411. One end of the headrest beam 411 is connected to the headrest fixing frame 414a. In this way, the third angle adjuster 413a can be driven to rotate by the second motor 412a, thereby driving one end of the headrest beam 411 to rotate relative to the headrest fixing frame 414a. The second motor 412b is connected to the third angle adjuster 413b (for example, through a planetary rod). The third angle adjuster 413b is connected to the other end of the headrest beam 411 and the headrest fixing frame 414b respectively. In this way, the third angle adjuster 413b can be driven to rotate by the second motor 412b, thereby driving one end of the headrest beam 411 to rotate relative to the headrest fixing frame 414b. Thus, the headrest beam 411 can be driven to rotate relative to the two headrest fixing frames 414a and 414b by the two second motors 412a and 412b. The headrest fixing frame 414a can be fixed on the backrest side panel 320a, and the headrest fixing frame 414b can be fixed on the backrest side panel 320b. In this way, the headrest beam 411 can be driven to rotate relative to the backrest side panel by the second motors.

[0059] In some embodiments, the headrest crossbeam 411 may be provided with two headrest guide rods 416a and 416b, as shown in FIG6D. The headrest support frame 420 is provided with two headrest feet 421a and 421b. The headrest foot 421a is inserted into the headrest guide rod 416a and fixedly connected to it, and the headrest foot 421b is inserted into the headrest guide rod 416b and fixedly connected to it, thereby fixing the headrest support frame 420 to the headrest rotation assembly 410. It can be understood that the positions of the headrest guide rods and the headrest feet can be interchanged. That is, two headrest feet can be provided on the headrest crossbeam 411, and two headrest guide rods corresponding to the two headrest feet can be provided on the headrest support frame 420.

[0060] As shown in Figures 7A, 7B and 7C, the support panel assembly 500 may include a support panel 510 and a sliding mechanism 520. The sliding mechanism 520 is fixed to the support panel 510 and is rotatably connected to the backrest frame 300 and can rotate relative to the backrest frame 300. The sliding mechanism 520 is used to make the support panel 510 move linearly relative to the backrest frame 300 so that the support panel 510 can unfold and retract.

[0061] In some embodiments, the support panel assembly 500 may further include a third motor 531, a first connecting plate 532, and a second connecting plate 533. The first connecting plate 532 and the second connecting plate 533 are both fixedly connected to the backrest frame 300. For example, the backrest frame 300 may be provided with an upper crossbeam 350, and the first connecting plate 532 and the second connecting plate 533 may be welded to the upper crossbeam 350. The two sides of the sliding mechanism 520 are respectively rotatably connected to the first connecting plate 532 and the second connecting plate 532. The third motor 531 is fixed on the first connecting plate 532 and connected to the sliding mechanism 520, and is used to drive the sliding mechanism 520 to rotate relative to the first connecting plate 532 and the second connecting plate 532, that is, to rotate relative to the backrest frame 300. Specifically, the sliding mechanism 520 may be provided with a toothed plate 521, which has teeth extending in the circumferential direction. The toothed plate 521 meshes with the gear 534, and the third motor 531 is connected to the gear 534. In this way, when the third motor 531 rotates, it can drive the gear 534 to rotate, and the rotation of the gear 534 will cause the toothed plate 521 to rotate, thereby causing the sliding mechanism 520 to rotate.

[0062] As shown in Figure 7C, in some embodiments, the sliding mechanism 520 may include a base plate 522, a first side plate 523, a second side plate 524, and a third driving device. The first side plate 523 is rotatably connected to the first connecting plate 532, and the second side plate 524 is rotatably connected to the second connecting plate 533. The toothed plate 521 is fixed on the first side plate 523, and the base plate 522 is fixedly connected to the support panel 510. The base plate 522 is also slidably connected to the first side plate 523 and the second side plate 524 respectively, and can slide relative to the first side plate 523 and the second side plate 524. The third driving device is connected to the base plate 522, the first side plate 523, and the second side plate 524 respectively, and is used to drive the base plate 522 to slide relative to the first side plate 523 and the second side plate 524. The third driving device can be a ball screw mechanism, which includes a fourth motor 5261, a lead screw 5262, and a nut 5263. The fourth motor 5261 can be fixed on a motor bracket 5264. The motor bracket 5264 can be fixedly connected to the first side plate 523 and / or the second side plate 524. One end of the lead screw 5262 passes through the fourth motor 5261 to connect the two. The other end of the lead screw 5262 passes through the nut 5263 and is threadedly connected to it. The base plate 522 is fixedly connected to the nut 5263. When the fourth motor 5261 rotates, it can drive the lead screw 5262 to rotate. The rotation of the lead screw 5262 causes the nut 5263 to slide along the lead screw 5262, thereby causing the base plate 522 to slide along the lead screw 5262. The base plate 522, the first side plate 523, and the second side plate 524 can all be slidably connected by a slide rail assembly 525. The slide rail assembly 525 includes a guide rail and a slider. The slider can slide in the guide rail. The guide rail and the slider are fixed to the two components respectively, so that the two components can be slidably connected. The slide rail assembly is a conventional device in the field, and its structure and principle will not be described in detail here.

[0063] When the car seat frame is in its designed state and semi-open state, the support panel 510 and the sliding mechanism 520 are both hidden behind the backrest frame 300 and are basically parallel to the backrest frame 300. When the car seat frame is in its fully open state, compared with the designed state and semi-open state, the third motor 531 drives the sliding mechanism 520 and the support panel 510 to rotate about 180 degrees relative to the backrest frame 300, so as to flip the sliding mechanism 520 and the support panel 510 out from the backrest frame 300. Then, the fourth motor 5261 drives the support panel 510 to slide away from the backrest frame 300, so that the length of the entire car seat frame is extended, making it easier for the occupant to lie down.

[0064] Referring again to Figures 1A-1C, the car seat frame may further include a slider 600. The slider 600 is mounted on the vehicle body frame, and the base 100 is mounted on the slider 600. The base 100 can be slidably connected to the vehicle body frame via the slider 600, thereby making the fore-and-aft position of the entire car seat frame adjustable. As shown in Figure 2, the slider 600 may include two slide rail assemblies 610a and 610b. The base bracket 110a is connected to the slide rail assembly 610a, and the base bracket 110b is connected to the slide rail assembly 610b. The slide rail assemblies 610a and 610b are mounted on the vehicle body frame.

[0065] Figures 8A and 8B illustrate the motion principle of a car seat frame. Solid dots represent connection points between components, and arrows indicate the direction of movement for each component. As can be seen from the figures, when the car seat frame switches from its designed state to its fully extended state, the backrest frame 300 rotates counter-clockwise relative to the base 100. In response to this rotation, the end of the seat cushion frame 200 hinged to the backrest frame 300 rotates clockwise relative to the hinge point, while the other end of the seat cushion frame 200 slides to the left relative to the base 100. The headrest frame 400 rotates counter-clockwise relative to the backrest frame 300, and the support panel assembly 500 rotates clockwise relative to the backrest frame 300. After rotation, the support panel assembly 500 slides a distance to the left.

[0066] The car seat frame of this embodiment can switch between a designed state, a semi-expanded state, and a fully expanded state by rotating the backrest frame 300 relative to the base 100, rotating the headrest frame 400 relative to the backrest frame 300, and rotating the support panel assembly 500 relative to the backrest frame 300, thereby enabling the car seat to have multiple uses and meet user needs.

[0067] Another embodiment of this disclosure also provides an automobile seat, which includes the automobile seat frame as described in the above embodiments.
