[0025] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0026] In the related art, when a vehicle crashes at a high altitude, the passengers will be subjected to a large impact force in the vertical direction, thereby causing damage to the passengers' lives.

[0027] Reference below Figure 1-Figure 2 A crash-resistant seat assembly according to an embodiment of the present invention is described.

[0028] The crash-resistant seat assembly 100 according to the present invention includes: a base 11, chair legs 13 and a buffer component. A backrest 12 is provided at the edge of the base 11, and the backrest 12 extends in a direction away from the base 11; the chair legs 13 are provided on the backrest 12 and the backrest 12 can slide along the chair legs 13; the buffer component is provided in the chair legs 13, and the buffer component is suitable for absorbing the impact force generated when the chair basin falls along the chair legs 13.

[0029] In some specific embodiments, the crash-resistant seat assembly 100 consists of a base 11, chair legs 13 and buffers. The base 11 is set on the vehicle. The base 11 can provide a rest seat for the occupants. A backrest 12 is set on the edge of the base 11. The backrest 12 extends in a direction away from the base 11. The backrest 12 is slidably connected to the chair legs 13. The sliding design of the chair legs 13 and the backrest 12 ensures the stability and reliability of the seat in multiple directions and prevents the base 11 from moving unnecessary during impact. Buffers are set in the leg chair. When the vehicle encounters a severe impact such as a crash, the backrest 12 will slide along the chair 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, reducing the risk of injury to the occupants.

[0030] According to the crash-resistant seat assembly 100 of the present invention, the backrest 12 is slidably connected to the chair legs 13, and the buffer parts are arranged in the chair legs 13. When the vehicle encounters a violent impact such as a crash, the backrest 12 will slide along the chair legs 13 under the action of the impact force. The buffer parts 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.

[0031] According to one embodiment of the present invention, a first sliding fitting portion is provided on the side of the backrest 12 facing away from the base 11, and a second sliding fitting portion that cooperates with the first sliding fitting portion is formed on the chair leg 13. When the vehicle encounters a violent impact such as a crash, the backrest 12 will slide along the chair leg 13 under the action of the impact force. The first sliding fitting portion on the backrest 12 cooperates with the second sliding fitting portion on the chair leg 13 to ensure that the backrest 12 moves smoothly along the chair leg 13, reducing instantaneous high acceleration, thereby reducing the risk of injury to the occupants. The energy dispersion mechanism of the base 11 during the sliding process can reduce local concentrated force and further improve the safety of the occupants.

[0032] According to one embodiment of the present invention, the first sliding fitting part is configured as a slider 121, and the second sliding fitting part is configured as a slide groove 101. The design of the slider 121 and the slide groove 101 can ensure smoothness during the sliding process and reduce the jamming phenomenon, thereby improving the stability and reliability of the crash-resistant seat assembly 100 during impact. The smooth movement of the slider 121 in the slide groove 101 can play a certain shock-absorbing role, further reducing the impact of the impact on the occupant. The design of the slider 121 and the slide 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 member is constructed as a raised portion arranged in the slide groove 101 and protruding from the inner wall of the slide groove 101. The raised portion is suitable for abutting against the outer surface of the slider 121. When the slider 121 slides along the slide groove 101, the raised portion will contact the outer surface of the slider 121 and generate resistance. When the crash-resistant seat assembly 100 is subjected to a vertical impact, the slider 121 slides in the slide groove 101, contacts and squeezes the raised portion. The raised portion 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 raised portion is constructed to be arranged in a plurality of intervals along the extension direction of the chair leg 13. The interval arrangement of the plurality of raised portions enables the slider 121 to squeeze the plurality of raised portions in sequence during the sliding process. Each raised portion absorbs a portion of the energy. The gradually deformed raised portions ensure the gradual absorption of the impact energy, avoiding the instantaneous high acceleration that may be caused by a single raised portion absorbing a large amount of energy at one time, and realizing multi-stage energy absorption at the same time. The multi-stage energy absorption mechanism ensures that effective protection can be provided under different impact intensities, thereby improving the safety of the occupants.

[0035] According to one embodiment of the present invention, a first side wall and a second side wall are formed in the slide groove 101 and are arranged opposite to each other. The raised portion is constructed as a first protrusion 21 provided on the first side wall and a second protrusion 22 provided on the second side wall. The first protrusion 21 and the second protrusion 22 are arranged at intervals 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 plastically deform and absorb impact energy under the pressure of the slider 121. The design of the double-sided protrusions can effectively absorb and disperse the impact energy, reduce the risk of injury to the occupants, and further improve the safety of the occupants. The design of the double-sided protrusions can be adjusted according to occupants of different weights and body shapes 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 cross bar 23, which is arranged on the backrest 12 and located at the top of the chair leg 13. The support cross bar 23 and the chair leg 13 abut against each other to limit the movement of the base 11 along the extension direction of the backrest 12. The support cross bar 23 can effectively prevent the base 11 from sliding along the backrest 12 when subjected to a slight impact, thereby increasing the overall stability of the crash-resistant seat assembly 100. The support cross bar 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 chair leg 13 remains unchanged when the vehicle is subjected to a slight impact, thereby enhancing the stability between the base 11 and the chair leg 13.

[0037] According to one embodiment of the present invention, the crash-resistant seat assembly 100 further includes: a limiting rod 24, which is connected to the backrest 12 and the support cross bar 23 respectively. The limiting rod 24 is suitable for limiting the movement of the base 11 relative to the chair leg 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 crash) exceeds a preset threshold, the limiting rod 24 will break to ensure that the base 11 can move in an expected manner when encountering extreme situations, thereby activating the buffering energy absorption mechanism. When the limiting rod 24 breaks, the base 11 can slide freely along the slide groove 101 in the chair leg 13, and the slider 121 provided on the backrest 12 will move with the base 11 and begin to squeeze the protrusion in the chair leg 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 life safety of the occupant.

[0038] According to one embodiment of the present invention, the limit rod 24 is constructed as an elastic part. The limit 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 fail easily under multiple small-amplitude impacts. The limit rod 24 can also be designed into a coil spring, leaf spring, etc. These structures can produce larger elastic deformation when subjected to axial loads, thereby absorbing more energy. When the impact force applied to the limit rod 24 does not reach the fracture threshold, the limit rod 24 can be restored to its original state through elasticity, which allows the crash-resistant seat assembly 100 to continue to be used after a small-scale impact, thereby 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 pull rod 24 needs to be set with an appropriate pre-tightening force so that it remains tightened in the absence of impact, and only when subjected to an impact force beyond the preset range will it undergo significant deformation or breakage.

[0040] The vehicle according to the present invention will be briefly described below.

Since the vehicle according to the present invention is provided with the anti-crash seat assembly 100 of the above embodiment, the anti-crash seat assembly 100 can absorb the impact force of the occupants in the vertical direction when the vehicle crashes at a high altitude, thereby improving the safety and reliability of the vehicle.
