Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] In the current dramatic transformation of the automotive industry, intelligent driving and intelligent cockpit are undoubtedly the two core areas that major domestic automakers are competing for in the fierce competition. The zero-gravity seat is an innovative product that is further refined from the field of intelligent cockpit.

[0042] In the event of a vehicle collision, especially a frontal collision, the force applied to the car seat may cause the passenger's chest to be strongly squeezed against the seat belt. In particular, when the backrest is in a large backward tilt state (such as a zero pressure state), when encountering a collision or sudden braking, the occupant is likely to be relatively squeezed against the seat, causing spinal compression, posing a major safety hazard, and the risk of injury is much greater than when the backrest is in a small backward tilt state.

[0043] In the related art, the patent with the patent publication number WO2023178831A1 discloses a recovery and energy absorption mechanism for a seat back and a car seat. The patent absorbs energy by deforming the parts during the rotation of the backrest. The mechanism cannot self-lock after a collision, and the mechanism fails in a secondary collision, posing a safety hazard. The Chinese invention patent with the patent publication number CN113459911A discloses a front collision energy absorption structure for a car seat and a seat with the front collision energy absorption structure. The patent adopts a planetary gear structure to deform the planetary gear to absorb energy. The energy absorption mechanism is complex and the structure is unstable. The Chinese invention patent with the patent publication number CN117565761A discloses a backrest quick return mechanism and a seat cushion quick return mechanism based on a zero-gravity seat. The patent adopts a lock pin bracket structure to achieve quick return after electric unlocking. The mechanism cannot self-lock after a collision, and the mechanism fails in a secondary collision, posing a safety hazard.

[0044] In the related art, when a vehicle encounters a collision or sudden braking, there is a technical problem that the occupants are easily squeezed relative to the seat, causing spinal compression, which poses a great safety hazard. The embodiment of the present application provides a seat mechanism 100 that can be quickly reset, which can at least to some extent solve the technical problem that when a vehicle encounters a collision or sudden braking, the occupants are easily squeezed relative to the seat, causing spinal compression, which poses a great safety hazard.

[0045] like Figure 1 and Figure 2 As shown, the seat mechanism 100 capable of rapid reset includes: a backrest frame 110, a fixed base 120 under the backrest, a self-locking recliner 130, a synchronization rod 140, a flywheel 150, an angle adjustment driver 160 and a reset assembly 170. It should be noted that, in order to facilitate observation of the self-locking recliner 130, Figure 2 It is a schematic diagram of an explosion, in which the self-locking recliner 130 is exploded to the outside of the fixed base 120 under the backrest. In the absence of an explosion, the self-locking recliner 130 is located between the backrest frame 110 and the fixed base 120.

[0046] The lower fixed base 120 of the backrest is used for fixed connection with the seat cushion frame, and the backrest frame 110 and the lower fixed base 120 of the backrest are rotationally connected via a self-locking angle adjuster 130 .

[0047] The self-locking recliner 130 is located between the backrest frame 110 and the fixed base 120. The structure of the self-locking recliner 130 is diverse and is known to those skilled in the art. The installation methods of different types of self-locking recliners 130 are also known to those skilled in the art. The specific structure of the self-locking recliner 130 is not limited in this application. It is easy to understand that the backrest frame 110 is fixed to the rotating part of the self-locking recliner 130, and the fixed base 120 under the backrest is fixed to the fixed part of the self-locking recliner 130. The rotating part can rotate relative to the fixed part, thereby realizing the rotation of the backrest frame 110 relative to the fixed base 120 under the backrest.

[0048] The synchronization rod 140 is fixedly connected to the self-locking angle adjuster 130 , and the flywheel 150 is fixedly connected to the synchronization rod 140 .

[0049] The synchronization rod 140 is fixedly connected to the rotating part of the self-locking recliner 130. The rotation of the synchronization rod 140 can drive the rotating part to rotate, thereby driving the backrest frame 110 to rotate. Since the flywheel 150 is fixed on the synchronization rod 140, the flywheel 150 will rotate synchronously with the synchronization rod 140. In some embodiments, the flywheel 150 is sleeved on the synchronization rod 140, and the synchronization rod 140 and the flywheel 150 are fixedly connected by splines.

[0050] The angle adjustment driver 160 is in transmission connection with the synchronization rod 140 to adjust the angle of the backrest frame 110 .

[0051] The angle adjustment driver 160 may include components such as a motor and an output gear, and its structure is diverse and well known to those skilled in the art. The angle adjustment driver 160 drives the synchronization rod 140 to rotate, which in turn can drive the backrest frame 110 to rotate, thereby adjusting the tilt angle of the backrest.

[0052] The reset assembly 170 is installed on the backrest frame 110 , and the flywheel 150 is located inside the reset assembly 170 . The reset assembly 170 can drive the flywheel 150 to rotate so as to reset the backrest frame 110 .

[0053] The reset assembly 170 is fixedly connected to the backrest frame 110, and the reset assembly 170 will rotate synchronously with the backrest frame 110. When the vehicle collides or brakes suddenly, the reset assembly 170 will work, and the reset assembly 170 will drive the flywheel 150 to rotate. Since the flywheel 150 and the synchronization rod 140 are fixedly connected, the synchronization rod 140 will be driven to rotate, and then the rotating part of the self-locking recliner 130 will be driven to rotate, and then the backrest frame 110 of the seat will be driven to rotate, so that the backrest frame 110 is reset.

[0054] When the backrest is in a state of large backward tilt (such as zero pressure state), when encountering a collision or sudden braking, the occupant is easily squeezed relative to the seat, causing spinal compression, posing a greater safety hazard. The risk of personal injury is much greater than when the backrest is in a state of small backward tilt. Therefore, resetting refers to driving the backrest frame 110 to rotate forward, rotating it to an unadjusted state, so that the inclination angle of the backrest becomes smaller, reducing the occupant's spinal compression.

[0055] Under normal driving conditions of the vehicle, the tilt degree of the backrest can be achieved by the angle adjustment driver 160 driving the synchronous rod 140 to rotate, thereby driving the self-locking angle adjuster 130 to rotate, thereby driving the backrest frame 110 to rotate. When the vehicle collides or brakes suddenly, the backrest can be quickly reset under the action of the reset component 170. Specifically, the reset component 170 drives the flywheel 150 to rotate, thereby driving the synchronous rod 140 to rotate, thereby driving the self-locking angle adjuster 130 to rotate, thereby driving the backrest frame 110 to rotate forward and reset, thereby absorbing the energy of the seat forward, and at the same time driving the human body to quickly reset, reducing the impact force transmitted to the seat and the passenger's spine, and improving the safety of the seat. In addition, since the present invention has a self-locking angle adjuster 130, the backrest frame 110 and the fixed base 120 under the backrest are always in a self-locking state, ensuring that the backrest frame 110 always remains effectively locked under complex working conditions such as secondary collisions, thereby improving safety.

[0056] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the reset assembly 170 includes: a housing 171, a guide member 172, a moving member 173 and a driving member 174. The housing 171 is fixedly connected to the backrest frame 110; the guide member 172 is fixedly connected to the housing 171, and the guide member 172 has a channel 172a and an outlet 172d connected to the channel 172a, the moving member 173 is located in the channel 172a, and the flywheel 150 is located next to the outlet 172d; the driving member 174 is installed on the guide member 172 and is located on the side of the moving member 173 away from the outlet 172d, and the driving member 174 can drive the moving member 173 to be discharged from the outlet 172d, so that the moving member 173 drives the flywheel 150 to rotate.

[0057] The housing 171 is fixedly connected to the backrest frame 110, and the guide member 172 is used to guide the moving member 173 and is also fixedly connected to the housing 171. The guide member 172 is provided with a channel 172a and an outlet 172d communicating with the channel 172a. The moving member 173 is located in the channel 172a and can be discharged through the outlet 172d. The driving member 174 is installed on the guide member 172. The driving member 174 is installed on the side of the moving member 173 away from the outlet 172d. When the vehicle collides or brakes suddenly, the driving member 174 will drive the moving member 173 to move toward the side of the outlet 172d and discharge the moving member 173 through the outlet 172d. The moving member 173 still has kinetic energy after being discharged from the outlet 172d. It will contact the flywheel 150 and push the flywheel 150 to rotate. The flywheel 150 will drive the synchronization rod 140 to rotate, and the synchronization rod 140 will drive the self-locking adjuster 130 to rotate, thereby driving the backrest frame 110 to rotate forward to achieve the resetting of the backrest frame 110.

[0058] The structure of the driving member 174 is diverse. The driving member 174 may include a spring and a spring stopper. When the vehicle is running normally, the spring stopper stops the spring so that the spring is in a compressed state. When the vehicle collides or brakes suddenly, the spring stopper moves and no longer contacts the spring, unlocking the spring. The spring will restore its deformation and exert a force on the moving member 173 so that the moving member 173 moves toward one side of the outlet 172d. The driving member 174 may also be an electric push rod or a hydraulic cylinder. When the vehicle is running normally, the electric push rod or the hydraulic cylinder is in a contracted state. When the vehicle collides or brakes suddenly, the electric push rod or the hydraulic cylinder gradually extends so that the moving member 173 moves toward one side of the outlet 172d.

[0059] In some embodiments, an entrance connected to the channel 172a is also provided on the guide member 172, and the moving member 173 is placed in the channel 172a through the entrance. Of course, the entrance can also be set, and the moving member 173 is placed in the channel 172a through the outlet 172a.

[0060] In some embodiments, the driving member 174 includes an explosive and an igniter. The explosive is disposed in the channel 172a; the igniter is mounted on the guide member 172, and the igniter is used to ignite the explosive.

[0061] The composition of the explosive may be gunpowder, etc. The explosive may be ignited and explode in a short time. The igniter is used to ignite the explosive, causing the explosive to explode. After the explosive explodes, the high-pressure gas generated by the explosion rapidly expands in the channel 172a, thereby pushing the moving part 173 toward one side of the outlet 172d and being discharged through the outlet 172d. These embodiments push the moving part 173 by the explosion of the explosive, and can respond to push the moving part 173 in a short time, so that the backrest frame 110 can quickly rotate forward and reset within 100ms, which helps to improve the safety of the seat.

[0062] In some embodiments, the igniter is electrically connected to the ECU controller of the vehicle, and the igniter is controlled by the ECU controller. When the vehicle collides, the collision sensor in the vehicle transmits the collision signal to the vehicle ECU controller, and the ECU controller sends a detonation command signal to the igniter after performing a logical operation. After receiving the detonation command signal, the igniter ignites the explosive.

[0063] In some embodiments, the reset assembly 170 also includes a collecting member 175, which is disposed next to the driving member 174. The collecting member 175 has a accommodating cavity and an inlet 175a connected to the accommodating cavity. The collecting member 175 is installed on the outer shell 171, and the inlet 175a is arranged opposite to the outlet 172d of the guide member 172 so that the moving member 173 can enter the accommodating cavity through the inlet 175a.

[0064] After the moving part 173 pushes the flywheel 150, it will separate from the flywheel 150. After the moving part 173 separates from the flywheel 150, the moving part 173 still has kinetic energy, and the moving part 173 will continue to move forward and enter the accommodating chamber through the entrance 175a and be stored in the accommodating chamber. With this design, the moving part 173 can be stored in the collector without falling, which facilitates the collection of the moving part 173 and allows the moving part 173 to be reused. The shape and size of the accommodating chamber are not limited in this application, and the user can make an adaptive design according to the size and number of the moving part 173.

[0065] In some embodiments, the collecting member 175 is detachably connected to the shell 171. After the moving member 173 is stored in the collecting member 175, the collecting member 175 can be removed from the shell 171 to pour out the moving member 173 in the collecting member 175 so that the moving member 173 can be reused.

[0066] In some embodiments, the housing 171 includes a bottom shell 1711 and a cover plate 1712, and the guide member 172 and the collecting member 175 are both installed on the bottom shell 1711; the cover plate 1712 is installed on the bottom shell 1711 and is combined with the bottom shell 1711 to form a guide groove (1711a), the flywheel 150 is located between the bottom shell 1711 and the cover plate 1712, at least part of the flywheel 150 is located in the guide groove 1711a, and the outlet 172d and the inlet 175a are both connected to the guide groove 1711a.

[0067] The bottom shell 1711 is fixedly connected to the backrest frame 110. In some embodiments, the bottom shell 1711 is fixedly connected to the backrest frame 110 by bolts. The bottom shell 1711 and the cover plate 1712 are arranged relatively and fixedly connected. In some embodiments, the bottom shell 1711 and the cover plate 1712 are fixedly connected by bolts. After the cover plate 1712 is connected to the bottom shell 1711, a guide groove 1711a is formed. The guide groove 1711a is used to provide guidance for the moving member 173. The outlet 172d is connected to the guide groove 1711a so that the guide member 172 enters the guide groove 1711a after being discharged from the outlet 172d. At least part of the flywheel 150 is located in the guide groove 1711a so that the moving member 173 in the guide groove 1711a can contact the peripheral wall of the flywheel 150, driving the flywheel 150 to rotate. The inlet 175a is communicated with the guide groove 1711a, so that the moving member 173 in the guide groove 1711a can enter the accommodating cavity through the inlet 175a.

[0068] It is easy to understand that avoidance holes for avoiding the synchronization rod 140 are opened on the bottom shell 1711 and the cover plate 1712, so that the synchronization rod 140 can pass through the cover plate 1712 to connect with the flywheel 150 and pass through the bottom shell 1711 to connect with the self-locking adjuster 130.

[0069] In some embodiments, along the circumference of the flywheel 150, a plurality of limiting grooves 150a are spaced apart on the outer circumference of the flywheel 150, and the moving part 173 is spherical and is provided with a plurality of them. Under the action of the driving part 174, at least a portion of the moving part 173 can be located in the limiting groove 150a to drive the flywheel 150 to rotate.

[0070] The moving part 173 is spherical, and at least a portion of the moving part 173 can be located in the limiting groove 150a. After the moving part 173 is discharged from the outlet 172d, the moving part 173 still has kinetic energy, and at least a portion of the moving part 173 will be located in the limiting groove 150a, contacting the side wall of the limiting groove 150a. Since the moving part 173 has kinetic energy, the moving part 173 will move forward along the guide groove 1711a, and the moving part 173 will contact the side wall of the limiting groove 150a, and then the moving part 173 can drive the flywheel 150 to rotate. Under the action of multiple moving parts 173, the flywheel 150 can continue to rotate, thereby causing the backrest frame 110 to rotate forward and reset.

[0071] It is easy to understand that the size of the channel 172a should be larger than the size of the moving member 173 so that the moving member 173 can move along the channel 172a. In some implementations, the cross section of the channel 172a is circular, and the moving member 173 is a steel ball.

[0072] In some embodiments, the channel 172a includes a first channel 172b and a second channel 172c that are connected; the first channel 172b is arranged along the length direction of the synchronization rod 140, the second channel 172c is arranged at an angle to the first channel 172b, and the second channel 172c is J-shaped, the outlet 172d is arranged on the side of the second channel 172c away from the first channel 172b, and the moving part 173 is arranged in the first channel 172b and / or the second channel 172c.

[0073] The first channel 172b is arranged along the length direction of the synchronization rod 140, which means that the length direction of the first channel 172b is parallel to the synchronization rod 140. The first channel 172b is arranged along the length direction of the synchronization rod 140, which can utilize the space in the width direction of the seat. The second channel 172c is designed in a J-shape, which utilizes the space in the height and length direction of the seat. Such a design helps to reduce the outer dimensions of the guide member 172, reduce the space occupied by the guide member 172, and facilitate the installation of the guide member 172. After such a design, the driving member 174, the guide member 172, the guide groove 1711a and the collecting member 175 are surrounded to form a runway-shaped structure. The angled setting can be a right angle setting, an obtuse angle setting or an acute angle setting. In some embodiments, the first channel 172b and the second channel 172c are arranged vertically.

[0074] In some embodiments, reference may be made to Figure 2As shown, the driving member 174 and the collecting member 175 are located on the upper side of the guide member 172, the guide member 172 is located on the lower side, the driving member 174 and the collecting member 175 are arranged side by side along the length direction of the seat, and the collecting member 175 is located on the upper side of the outlet 172d. When the driving member 174 is not started, the moving member 173 is located in the arc section of the second channel 172 under the action of gravity. When the driving member 174 is started, the moving member 173 moves upward along the arc section, passes through the guide groove 1711a, and enters the collecting member 175.

[0075] In some embodiments, the restoring assembly 170 is disposed inside the backrest frame 110 , and the restoring assembly 170 is located between the angle adjustment driver 160 and the backrest frame 110 .

[0076] The backrest frame 110 has a connecting arm 113, a first support arm 111 and a second support arm 112. The first support arm 111 and the second support arm 112 are arranged at intervals. The connecting arm 113 connects the upper ends of the first support arm 111 and the second support arm 112 together. It is easy to understand that the lower fixed base 120 and the self-locking angle adjuster 130 of the backrest are both arranged at the lower ends of the first support arm 111 and the second support arm 112. The reset assembly 170 is arranged on the inner side of the backrest frame 110, that is, the reset assembly 170 is arranged between the first support arm 111 and the second support arm 112, that is, the first support arm 111 is arranged on the side close to the second support arm 112, or the second support arm 112 is arranged on the side close to the first support arm 111. The reset assembly 170 is arranged on the inner side of the backrest frame 110, so that the space between the first support arm 111 and the second support arm 112 can be utilized to reduce the space occupied by the seat mechanism 100 that can be quickly reset in the length direction of the synchronization rod 140.

[0077] In some embodiments, two self-locking angle adjusters 130 are provided. The two self-locking angle adjusters 130 are respectively provided on a side of the first support arm 111 away from the second support arm 112 and a side of the second support arm 112 away from the first support arm 111 .

[0078] In some embodiments, two reset assemblies 170 are provided. The two reset assemblies 170 are respectively provided on a side of the first support arm 111 close to the second support arm 112 and a side of the second support arm 112 close to the first support arm 111 .

[0079] The working principle of the seat mechanism 100 capable of rapid reset of the present application is described below:

[0080] Under normal vehicle driving conditions, the occupants can control the working mode of the angle adjustment driver 160 so that the angle adjustment driver 160 drives the synchronization rod 140 to rotate, which can then drive the rotating part of the self-locking angle adjuster 130 to rotate, and then the backrest frame 110 to rotate, thereby adjusting the inclination angle of the backrest frame 110 to a comfortable state.

[0081] When the vehicle collides or brakes suddenly, the collision sensor in the vehicle transmits the collision signal to the vehicle ECU controller. After logical operation, the ECU controller sends a detonation command signal to the igniter. After receiving the detonation command signal, the igniter ignites the explosive, and the explosive explodes. After the explosive explodes, the high-pressure gas generated by the explosion expands rapidly in the channel 172a, thereby pushing the steel balls to move in the channel 172a. Finally, multiple steel balls enter the guide groove 1711a in turn through the outlet 172d, and the moving part 173 moves toward one side of the outlet 172d and is discharged through the outlet 172d. After the moving part 173 is discharged from the outlet 172d, the moving part 173 still has kinetic energy, and the moving part 173 contacts the side wall of the limiting groove 150a, driving the flywheel 150 to rotate. Under the action of multiple steel balls, the flywheel 150 can continue to rotate, so that the backrest frame 110 rotates forward and resets, thereby driving the self-locking angle adjuster 130 to rotate, thereby driving the backrest frame 110 to rotate forward and reset, thereby absorbing the energy of the seat forward, and at the same time driving the human body to quickly reset, reducing the impact force transmitted to the seat and the passenger's spine, and improving the safety of the seat. In addition, due to the self-locking angle adjuster 130, when the backrest frame 110 is reset to any angle, the backrest frame 110 and the fixed base 120 under the backrest are always in a self-locking state, ensuring that under complex working conditions such as secondary collisions, the backrest frame 110 always remains effectively locked, thereby improving safety.
