[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0026] In related technologies, when a vehicle crashes from a height, the occupants will be subjected to a large impact force in the vertical direction, which will cause damage to the occupants' lives.
[0027] The following is for reference. Figures 1-2 A crash-resistant seat assembly according to an embodiment of the present invention is described.
[0028] The anti-fall seat assembly 100 according to the present invention includes: a base 11, a seat leg 13 and a buffer member. A backrest 12 is provided at the edge of the base 11 and extends in a direction away from the base 11. The seat leg 13 is disposed on the backrest 12 and the backrest 12 is slidable along the seat leg 13. The buffer member is disposed in the seat leg 13 and is adapted to absorb the impact force generated when the seat falls along the seat leg 13.
[0029] In some specific embodiments, the crash-resistant seat assembly 100 consists of a base 11, seat legs 13, and a buffer. The base 11 is installed on the vehicle and can provide a resting seat for the occupants. A backrest 12 is provided on the edge of the base 11, extending away from the base 11. The backrest 12 is slidably connected to the seat legs 13. The sliding design of the seat legs 13 and the backrest 12 ensures the stability and reliability of the seat in multiple directions and prevents the base 11 from moving unnecessarily during an impact. A buffer is provided inside the seat legs. When the vehicle encounters a severe impact such as a crash, the backrest 12 will slide along the seat legs 13 under the action of the impact force. The buffer can absorb the impact energy generated when the base 11 falls, reduce the impact force transmitted to the occupants, and slow down the falling speed of the base 11, thereby reducing the risk of injury to the occupants.
[0030] According to the present invention, the anti-crash seat assembly 100 slides the backrest 12 and the seat leg 13 together, and the buffer is disposed in the seat leg 13. When the vehicle encounters a violent impact such as a crash, the backrest 12 will slide along the seat leg 13 under the action of the impact force. The buffer can absorb the impact energy generated when the base 11 falls, reduce the impact force transmitted to the occupant, and slow down the falling speed of the base 11, thereby reducing the risk of injury to the occupant.
[0031] According to one embodiment of the present invention, a first sliding engagement portion is provided on the side of the backrest 12 away from the base 11, and a second sliding engagement portion is formed on the seat leg 13 to engage with the first sliding engagement portion. When the vehicle encounters a severe impact such as a crash, the backrest 12 will slide along the seat leg 13 under the action of the impact force. The first sliding engagement portion on the backrest 12 engages with the second sliding engagement portion on the seat leg 13 to ensure that the backrest 12 moves smoothly along the seat leg 13, reducing the instantaneous high acceleration, thereby reducing the risk of injury to the occupant. The energy distribution mechanism of the base 11 during the sliding process can reduce the local concentrated force and further improve the safety of the occupant.
[0032] According to one embodiment of the present invention, the first sliding engagement part is constructed as a slider 121, and the second sliding engagement part is constructed as a groove 101. The design of the slider 121 and the groove 101 can ensure the smoothness of the sliding process and reduce jamming, thereby improving the stability and reliability of the crash-resistant seat assembly 100 under impact. The smooth movement of the slider 121 in the groove 101 can play a certain role in shock absorption, further reducing the impact on the occupant. The design of the slider 121 and the groove 101 makes each component easy to inspect and replace, and the maintenance cost is low.
[0033] According to one embodiment of the present invention, the buffer is constructed as a protrusion disposed in the slide groove 101 and protruding from the inner wall of the slide groove 101. The protrusion is adapted to abut against the outer surface of the slider 121. When the slider 121 slides along the slide groove 101, the protrusion will contact the outer surface of the slider 121 and generate resistance. When the anti-fall seat assembly 100 is subjected to a vertical impact, the slider 121 slides in the slide groove 101, contacts the protrusion and squeezes the protrusion. The protrusion absorbs the impact energy through plastic deformation, thereby reducing the impact force transmitted to the occupant and improving the safety of the occupant.
[0034] According to one embodiment of the present invention, the protrusions are arranged in a plurality of spaced-apart configurations along the extension direction of the chair leg 13. The spaced arrangement of the plurality of protrusions causes the slider 121 to sequentially compress the plurality of protrusions during the sliding process. Each protrusion absorbs a portion of energy. The gradually deforming protrusions ensure the gradual absorption of impact energy, avoiding the instantaneous high acceleration that may result from a single protrusion absorbing a large amount of energy at once. At the same time, multi-stage energy absorption is achieved. The multi-stage energy absorption mechanism ensures effective protection under different impact intensities, thereby improving the safety of the occupants.
[0035] According to one embodiment of the present invention, a first sidewall and a second sidewall are formed in the slide groove 101 facing each other. The protrusion is constructed as a first protrusion 21 on the first sidewall and a second protrusion 22 on the second sidewall. The first protrusion 21 and the second protrusion 22 are spaced apart from each other, and the first protrusion 21 and the second protrusion 22 respectively abut against the slider 121. When the slider 121 slides along the slide groove 101, it will contact the first protrusion 21 and the second protrusion 22 and generate resistance. The first protrusion 21 and the second protrusion 22 begin to undergo plastic deformation under the pressure of the slider 121 and absorb impact energy. The design of the double-sided protrusion can effectively absorb and disperse impact energy, reduce the risk of occupant injury, and further improve occupant safety. The design of the double-sided protrusion can be adjusted according to occupants of different weights and body types to provide a more personalized protection effect. At the same time, it can adapt to horizontal impacts to a certain extent and provide all-round protection.
[0036] According to one embodiment of the present invention, the crash-resistant seat assembly 100 further includes a support crossbar 23, which is disposed on the backrest 12 and located at the top of the seat leg 13. The support crossbar 23 abuts against the seat leg 13 to restrict the base 11 from moving along the extension direction of the backrest 12. The support crossbar 23 can effectively prevent the base 11 from sliding along the backrest 12 when subjected to a minor impact, thereby increasing the overall stability of the crash-resistant seat assembly 100. The support crossbar 23 helps to maintain the structural integrity of the crash-resistant seat assembly 100, ensuring that the relative position between the base 11 and the seat leg 13 remains unchanged when the vehicle is subjected to a minor impact, thereby enhancing the stability between the base 11 and the seat leg 13.
[0037] According to an embodiment of the present invention, the anti-fall seat assembly 100 further includes a limiting rod 24, which is connected to the backrest 12 and the support crossbar 23 respectively. The limiting rod 24 is adapted to restrict the movement of the base 11 relative to the chair legs 13, further ensuring that the base 11 is stably fixed in a predetermined position under normal conditions. The limiting rod 24 can have a specific strength setting, that is, when the external force (such as the impact force during a fall) exceeds a preset threshold, the limiting rod 24 will break, so as to ensure that the base 11 can move in the expected way in extreme situations, thereby activating the buffer energy absorption mechanism. When the limiting rod 24 breaks, the base 11 can slide freely in the chair legs 13 along the slide groove 101. The slider 121 provided on the backrest 12 will move together with the base 11 and begin to squeeze the protrusion in the chair legs 13. The protrusion undergoes plastic deformation, thereby absorbing the impact energy generated when the base 11 falls, reducing the impact force transmitted to the occupant, and ensuring the occupant's life safety.
[0038] According to one embodiment of the present invention, the limiting rod 24 is constructed as an elastic element. The limiting rod 24 can be made of a material with high elasticity and good fatigue performance, such as spring steel, to ensure that it will not easily fail under multiple small-amplitude impacts. The limiting rod 24 can also be designed as a helical spring, leaf spring, etc. These structures can generate large elastic deformation when subjected to axial loads, thereby absorbing more energy. When the impact force on the limiting rod 24 does not reach the fracture threshold, the limiting rod 24 can elastically return to its original state. This allows the crash-resistant seat assembly 100 to continue to be used after small-scale impacts, improving the durability and economy of the crash-resistant seat assembly 100.
[0039] In addition, in order to ensure the stability of the crash-resistant seat assembly 100 during normal use, the limit rod 24 needs to be set with an appropriate preload so that it remains tight in the absence of impact and will only deform or break significantly when subjected to an impact force exceeding the preset range.
