Description

Technical Field

[0001] This utility model relates to the field of automotive seat structure technology, and in particular to a seat structure that reduces occupant injury when the seat is tilted at a large angle while the vehicle is in motion. Background Technology

[0002] As car driver assistance functions gradually improve and people's requirements for seat comfort increase, the existing seat posture angles during car driving are difficult to meet the needs of all passengers. Therefore, a series of seats with larger adjustment angles, such as zero-gravity seats, are gradually being used. However, as the adjustment angle increases, the safety risks to passengers increase during a collision.

[0003] In existing technologies, the large recline angle of seats is mainly used when the vehicle is stationary to avoid serious injury to passengers in the event of a collision. However, this configuration fails to meet the comfort requirements of passengers while the vehicle is in motion, and safety and comfort cannot be simultaneously achieved. This patent provides a new solution that can guarantee both comfort and safety.

[0004] Therefore, those skilled in the art need to provide a seat structure that protects occupants and reduces collision injuries when the seat is reclined at a large angle during vehicle operation. This technology can reduce passenger injuries from collisions when the seat is reclined at a large angle by adjusting the structure of the seat back and cushion, thereby ensuring passenger safety.

[0040] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1-13 As shown, a seat structure that reduces occupant injury during large seat tilts in a moving vehicle includes a backrest assembly 1 and a seat frame assembly 2 connected together. The backrest assembly 1 includes a first backrest reset mechanism 3, a second backrest reset mechanism 4, and a backrest body assembly 5. The first backrest reset mechanism 3 is connected to the right side of the bottom of the backrest body assembly 5, and the second backrest reset mechanism 4 is connected to the left side of the bottom of the backrest body assembly 5. The first backrest reset mechanism 3 includes a reset motor 301, a first limit pin 302, a motor fixing plate 303, a first backrest round nut 304, a first lower side plate 305, a first backrest reset bushing 306, a first backrest reset fixing seat 307, a first bushing 308, and a first locking assembly 310. The first locking assembly 310 is connected to the seat frame assembly 2.

[0042] The reset motor 301 is fixedly connected to the motor mounting plate 303, which is fixedly connected to the first lower side plate 305. The first lower side plate 305 is connected to the seat frame body assembly 6. The first back reset bushing 306 is riveted to the first back reset fixing seat 307. The first lower side plate 305 is connected to the first back reset fixing seat 307 through the first back round nut 304. The first back reset fixing seat 307 is connected to the back frame body assembly 5.

[0043] The first bushing 308 is embedded in the first through hole 3051 of the first lower side plate 305 and the first back reset fixing seat 307. The first limiting pin 302 passes through the first through hole 3052 on the first lower side plate 305 and the first arc-shaped groove 3071 on the first back reset fixing seat 307.

[0044] Specifically, the first limiting pin 302 limits the rotation of the first back reset fixing seat 307.

[0045] A portion of the inner ring of the first back reset fixing seat 307 is provided with teeth, and a gear is provided on the output shaft of the reset motor 301, and the gear meshes with the teeth for transmission.

[0046] Specifically, upon receiving a collision warning signal, the backrest actively resets, the first locking component 310 and the second locking component 408 quickly unlock, and the reset motor 301 rotates the backrest forward. When a collision occurs, the passive reset takes effect.

[0047] The seat frame assembly 2 includes a seat reset mechanism 7 and a seat frame body assembly 6.

[0048] The first locking assembly 310 includes a first electric telescopic rod 3101 and a first locking block 3102 connected together. The first electric telescopic rod 3101 controls the first locking block 3102 to extend into or out of the first bushing 308. The first locking assembly 310 is fixedly connected to the first unlocking fixing seat 311 via a first fixing piece 309. The first unlocking fixing seat 311 is connected to the seat frame assembly 2.

[0049] Specifically, when the seat needs to be changed from a large tilt position to a standard posture, the first locking assembly 310 and the second locking assembly 408 are in the unlocked state, that is, the first locking block 3102 and the second locking block 4082 are extended from the first bushing 308 and the second bushing 406. The backrest first performs an active reset operation: the reset motor 301 drives the first backrest reset fixing seat 307 to rotate through gears. The first backrest reset fixing seat 307 and the second backrest reset fixing seat 405 are driven by shaft transmission, which simultaneously drives the second backrest reset fixing seat 405 to rotate, thereby driving the backrest frame body assembly 5 to rotate forward.

[0050] When the backrest is passively reset, the first locking component 310 and the second locking component 408 are also in the unlocked state, thereby unlocking the first lower side plate 305 from the first backrest reset fixing seat 307 and the second lower side plate 403 from the second backrest reset fixing seat 405, so that the backrest frame body assembly 5 rotates forward at a set angle under the influence of collision inertia.

[0051] The left and right sides of the seat frame body assembly 6 are connected to the seat reset mechanism 7. The seat reset mechanism 7 includes a seat reset fixed seat 701, a front lifting drive plate assembly 702, a collapsible bolt 703 and a seat round nut 704. The front lifting drive plate assembly 702 includes a threaded sleeve 7021, a front lifting drive plate and a seat reset bushing 7023.

[0052] The seat reset bushing 7023 is riveted to the front lifting drive plate. One end of the threaded sleeve 7021 is fixed to the front lifting drive plate, and the other end of the threaded sleeve 7021 is connected to the upper part of the seat frame body assembly 6. The seat round nut 704 connects the front lifting drive plate and the seat reset fixing seat 701 together. The collapsible bolt 703 connects the seat reset fixing seat 701 to the front lifting drive plate. The seat reset fixing seat 701 is also connected to the lower part of the seat frame body assembly 6.

[0053] Specifically, during seat reset, the front end of the seat frame assembly 6 is subjected to inertial impact energy, causing the collapsible bolt 703 to break under a preset force value, thereby unlocking the seat reset fixing seat 701 from the front lifting drive plate 7022, and thus causing the front end of the seat frame assembly 6 to rotate downward.

[0054] The seat frame body assembly 6 is slidably connected to the slide rail assembly 8.

[0055] The second back reset mechanism 4 includes a second limiting pin 401, a second back round nut 402, a second lower side plate 403, a second back reset bushing 404, a second back reset fixing seat 405, a second bushing 406, and a second locking assembly 408.

[0056] The second lower side plate 403 is connected to the seat frame body assembly 6. The second back reset bushing 404 is riveted to the second back reset fixing seat 405. The second lower side plate 403 is connected to the second back reset fixing seat 405 through the second back round nut 402. The second back reset fixing seat 405 is connected to the back frame body assembly 5. The second bushing 406 is embedded in the second through hole 4031 of the second lower side plate 403 and the second back reset fixing seat 405. The second limiting pin 401 passes through the second through hole 4032 on the second lower side plate 403 and the second arc-shaped groove 4051 on the second back reset fixing seat 405. Specifically, the second limiting pin 401 limits the rotation of the second back reset fixing seat 405.

[0057] The second locking assembly 408 includes a second electrically operated telescopic rod 4081 and a second locking block 4082 connected together. The second electrically operated telescopic rod 4081 controls the second locking block 4082 to extend into or out of the second bushing 406. The second locking assembly 408 is fixedly connected to the second unlocking fixing seat 409 via a second fixing piece 407. The second unlocking fixing seat 409 is connected to the seat frame assembly 2.

[0058] The usage process of this utility model is as follows:

[0059] When the seat needs to be changed from a large recline position to a standard posture, the backrest first performs an active reset operation: at this time, the first locking component 310 and the second locking component 408 are both in the unlocked state, that is, the first locking block 3102 and the second locking block 4082 are extended from the first bushing 308 and the second bushing 406. The reset motor 301 drives the first back reset fixing seat 307 to rotate through gears. The first back reset fixing seat 307 and the second back reset fixing seat 405 are driven by shaft transmission, which simultaneously drives the second back reset fixing seat 405 to rotate, thereby driving the backrest frame body assembly 5 to rotate forward.

[0060] When the backrest is passively reset, the first locking component 310 and the second locking component 408 are also in the unlocked state, thereby unlocking the first lower side plate 305 from the first backrest reset fixing seat 307 and the second lower side plate 403 from the second backrest reset fixing seat 405, so that the backrest frame body assembly 5 rotates forward at a set angle under the influence of collision inertia.

[0061] When the seat is reset, the front end of the seat frame assembly 6 is subjected to inertial impact energy, causing the collapsible bolt 703 to break when it is subjected to a preset force value, thereby unlocking the seat reset fixing seat 701 from the front lifting drive plate 7022, and thus causing the front end of the seat frame assembly 6 to rotate downward.

[0062] like Figure 13 As shown, the large-angle seat safety protection mechanism allows passengers to maintain a comfortable posture with a large angle in the seat while the vehicle is in motion, thereby alleviating fatigue caused by long-term sitting. In the event of a vehicle collision, the skeletal structure changes back to a normal sitting posture, thus ensuring passenger safety.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
