Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to an anti-submersion structure for automotive seats and an automotive seat. Background Technology

[0002] With the increasing popularity of automobiles and the rising demands for their functionality, the safety, comfort, and practicality of vehicles are receiving more and more attention. In the event of a frontal collision, passengers are prone to being thrown forward, potentially resulting in serious injury. Given the ever-increasing safety requirements, incorporating fixed anti-throwing structures into the car seat frame can provide a certain degree of protection against this phenomenon.

[0003] The existing utility model patent CN202686538U proposes a car rear floor with a rear seat anti-submersion beam structure. This utility model pre-welds the anti-submersion beam to the front end of the rear floor body, so that its bottom edge forms a first closed cavity with the floor; at the same time, the inner plate of the front crossbeam of the rear floor and the inner side of the floor are welded together to form a second closed cavity, which together improves the local rigidity; the rear seat is directly fixed to the top surface of the anti-submersion beam through the mounting holes. When the vehicle is involved in a frontal collision, the beam immediately provides rigid blocking to prevent the seat cushion from "submerging" and sliding forward, thereby protecting the rear passengers.

[0004] In the above technical solution, the anti-submargin beam is welded to the front end of the rear floor to form a closed cavity that directly supports the rear seat. In the event of a collision, the beam prevents the seat from moving forward, thus protecting the occupants. However, the above device has the problem that the anti-submargin structure cannot be adaptively adjusted according to the passenger's body shape, resulting in low adaptability in terms of comfort and anti-submargin function. Since the anti-submargin beam is welded and fixed, it cannot be adaptively adjusted according to the passenger's body shape and weight. At the same time, the misfit of the anti-submargin beam will also affect the passenger's riding comfort and anti-submargin function. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-3 This application proposes an anti-submersion structure for automobile seats, comprising a seat frame 1, an anti-submersion structure 2, and a drive structure 3.

[0040] like Figure 1As shown, the seat frame 1 includes two symmetrically arranged wall panels 11 and a supporting horizontal tube 12 connected between the two wall panels 11; the anti-submersion structure 2 includes a sliding member 21 and a crossbeam 22. The sliding member 21 includes two sets, which are respectively located at the bottom of the two wall panels 11; the crossbeam 22 is located in the middle of the two wall panels 11, and its two ends are respectively perpendicular to the corresponding wall panels 11. The two ends of the crossbeam 22 are respectively slidably connected to the corresponding sliding member 21, so that the crossbeam 22 can slide back and forth along the bottom two ends of the wall panel 11; the driving structure 3 is located at the bottom of the two wall panels 11 and is drivenly connected to the crossbeam 22, so as to drive the crossbeam 22 to move back and forth along the bottom two ends of the wall panel 11.

[0041] Specifically, by replacing the traditional fixed welded structure with a sliding crossbeam 22, the sliding and adjustable crossbeam 22 plays a good role in preventing subsidence when passengers of different body sizes are seated. This avoids the protective failure caused by the non-adjustable position of the traditional fixed structure, while also solving the problem of poor comfort caused by excessive pressure due to body size, thus achieving a balance between safety and comfort.

[0042] like Figures 2-3 As shown, the sliding member 21 includes a sliding rod 211, a slider 212, and a mounting block 213. The sliding rod 211 is located at the bottom of the wall panel 11 and extends along both ends of the bottom of the wall panel 11. One end of the slider 212 is fitted onto the sliding rod 211 and slidably connected thereto, while the other end of the slider 212 is fixedly located at the bottom of the corresponding end of the crossbeam 22. Two mounting blocks 213 are respectively located at the top of both ends of the sliding rod 211 and are used to fix it to the bottom of the wall panel 11, so that a gap is formed between the sliding rod 211 and the bottom of the wall panel 11 for the slider 212 to slide.

[0043] Specifically, the motion mechanism of the slide bar 211 and the slider 212 is completely hidden at the bottom of the wall panel 11: the mounting block 213 serves as a rigid support for the slide bar 211 and also ensures that the slider 212 slides without interference through the reserved gap, so as to realize the smooth and low-friction displacement of the crossbeam 22 and ensure that the anti-submersion function is always in the best position; the hidden layout does not take up the seat space, the structure is compact, and it takes into account both space utilization and operational reliability.

[0044] like Figures 2-3As shown, the drive structure 3 includes a mounting beam 31 and a drive component 32. The mounting beam 31 comprises two beams, each located at one end of the slide rod 211 and parallel to the crossbeam 22. The drive component 32 includes a threaded rod 321, a motor 322, a drive block 323, and a guide rod 324. The threaded rod 321 is transversely positioned between the two mounting beams 31 and parallel to the slide rod 211. Both ends of the threaded rod 321 are rotatably connected to the corresponding mounting beams 31. The motor 322 is located on one of the beams. The drive block 323 is fixedly mounted on the bottom of the crossbeam 22 and is driven to the end of the corresponding threaded rod 321 for driving the threaded rod 321 to rotate. The drive block 323 is sleeved on the threaded rod 321 at one end and threadedly connected to it. The guide rod 324 includes two rods, which are symmetrically arranged on both sides of the threaded rod 321 and parallel to the threaded rod 321. The guide rod 324 slides through the drive block 323 and is fixed at both ends on the corresponding mounting beam 31.

[0045] Specifically, the combination of the lead screw and guide rod 324 converts the rotation of the motor 322 into high-precision linear displacement of the crossbeam 22: the double-sided guide rod 324 restricts the rotational freedom of the drive block 323, eliminates lateral swaying, and ensures positioning accuracy; the low-friction threaded transmission, together with the silent motor 322, achieves low-noise and long-life operation, providing a stable and reliable mechanical execution platform for subsequent adaptive adjustment, while the modular layout facilitates assembly and later upgrades.

[0046] like Figure 1 , Figure 3 As shown, the anti-submersion structure of the car seat also includes a sensing structure 4, which includes a pressure sensor 41 and a PLC controller 42. The pressure sensor 41 is located on the top of the crossbeam 22 and is used to receive the passenger's weight signal. The PLC controller 42 is fixed on the wall panel 11 and is electrically connected to the pressure sensor 41 and the drive structure 3. It is used to control the drive structure 3 to drive the crossbeam 22 to move according to the signal detected by the pressure sensor 41, and to make adaptive adjustments.

[0047] Specifically, the pressure sensor 41 senses the passenger's weight distribution in real time, and the PLC controller 42 drives the crossbeam 22 to automatically move to the most suitable support point. The adaptation of the crossbeam 22's position also improves the passenger's riding comfort and realizes adaptive anti-submersion by adjusting according to the passenger's body shape. The whole process does not require manual intervention from the passenger, which improves convenience and ensures that the protection effect and comfort are optimized simultaneously. Of course, an external manual controller can be connected here to make manual adjustments when the passenger's body shape and weight are not proportional.

[0048] like Figure 1 , Figure 3As shown, an anti-submersion structure for a car seat also includes a positioning structure 5. The positioning structure 5 includes positioning rods 51 and electromagnetic locking pins 52. There are two positioning rods 51, which are respectively fixed at the bottom of the two wall panels 11 and located at the top of the sliding member 21 and the drive structure 3. The positioning rods 51 extend along the bottom ends of the wall panels 11. On the side of the two positioning rods 51 facing each other, a plurality of positioning holes 501 are evenly opened along the movement direction of the crossbeam 22. There are two electromagnetic locking pins 52, which are respectively located at the two ends of the crossbeam 22 corresponding to the positioning rods 51 and are electrically connected to the PLC controller 42. The electromagnetic locking pins 52 can be inserted into the positioning holes 501 to lock the crossbeam 22 after the position is adjusted. At the same time, the shape of the insertion part of the electromagnetic locking pin 52 is adapted to the positioning hole 501, and the outer contour dimension of the insertion part is smaller than the inner contour dimension of the positioning hole 501.

[0049] Specifically, the electromagnetic locking system completes the insertion or withdrawal action under the instruction of the PLC controller 42. After the PLC controller 42 receives the passenger's body shape information and drives the crossbeam 22 to the appropriate position through the drive structure 3, it controls the electromagnetic locking pin 52 to be inserted into the positioning hole 501 of the corresponding positioning rod 51, so as to ensure the stability of the crossbeam 22 after adjustment and to effectively play its role in preventing submersion in the event of a collision.

[0050] This utility model also provides a car seat, including the above-mentioned car seat anti-submersion structure, which allows for adaptive adjustment of the crossbeam 22 according to passengers of different body types, taking into account both riding comfort and safety.

[0051] The PLC controller 42 and its control method, as well as the electromagnetic lock pin and its working principle mentioned above, are all existing technologies and will not be elaborated here.

[0052] The specific workflow is as follows:

[0053] After the passenger is seated, the pressure sensor 41 outputs the passenger's weight signal to the PLC controller 42. The PLC controller 42 sends a command to the drive structure 3 based on the signal. The motor 322 drives the threaded rod 321 to rotate, which drives the drive block 323 and the crossbeam 22 to move along the slide bar 211 to the optimal support position calculated by the PLC controller 42. After reaching the optimal support position, the PLC controller 42 controls the electromagnetic locking pin 52 to insert into the corresponding positioning hole 501 on the positioning rod 51, locking the crossbeam 22 in that position. This achieves adaptive anti-submersion for passengers of different body sizes. At the same time, the appropriate position of the crossbeam 22 also improves the comfort of the passenger.
