At the same time, the access channel formed by the front seats is narrow, which brings great inconvenience to the access of the rear passengers, especially the third-row passengers. In addition, there is no escape path. In the event of an emergency such as vehicle wading, collision deformation leading to power failure or malfunction, the conventional channel is easily blocked, and the passengers are trapped in the escape dilemma.

[0024] At present, users have higher and higher requirements for the flexibility of the layout of the automobile cabin space, but the current automobile seats mainly expand the storage space by simple folding. Due to the relatively long backrest, the horizontal space is occupied more after folding, the horizontal space in the cabin cannot be fully utilized, and the storage efficiency is relatively low. At the same time, the access channel formed by the front row seats is narrow, which brings great inconvenience to the access of the rear row, especially the third row of personnel, and lacks an escape path.

[0025] To solve the above problems, the embodiments of the present application provide an automobile seat with folding storage and emergency escape functions, which can effectively reduce the occupation of horizontal space, greatly expand the storage space, thereby fully utilizing the horizontal space in the cabin and significantly improving the storage efficiency. At the same time, in the event of an emergency, the automobile seat can be quickly folded to form a spacious emergency escape channel, providing a convenient escape path for the passengers, effectively solving the escape problem caused by the narrowness of the conventional channel, protecting the life safety of the driver and passengers in emergency situations, and greatly improving the practicality, comfort and safety and reliability of the automobile seat.

The slide rail mechanism 2 is arranged below the cushion framework 1 and connected with the cushion framework 1 through a cushion locking mechanism 6 and used for driving the cushion framework 1 to move in the front-back direction. The backrest framework 3 is fixedly connected with the slide rail mechanism 2, so that the backrest framework 3 can move forward and backward synchronously with the movement of the slide rail mechanism 2. The cushion driving mechanism 4 is connected with the cushion framework 1 and used for driving the cushion framework 1 to overturn upward, thereby creating conditions for the forward and backward movement and storage of the seat and significantly expanding the horizontal space. The locking driving mechanism 5 is arranged on the slide rail mechanism 2 and connected with the cushion locking mechanism 6 and used for controlling the unlocking and locking of the cushion locking mechanism 6, so as to realize the disconnection and connection of the cushion framework 1 and the slide rail mechanism 2, thereby facilitating the user to select the state of the cushion framework 1 as required.

[0028] Specifically, the slide rail mechanism 2 comprises a linear slide rail 21 and a slide rail driving assembly 22. The linear slide rail 21 is arranged at the bottom of the car seat and extends in the front-back direction. The slide rail driving assembly 22 is connected with the linear slide rail 21 and used for driving the linear slide rail 21 to drive the cushion framework 1 to move in the front-back direction. Specifically, the linear slide rail 21 comprises an inner rail 211 and an outer rail 212. The outer rail 212 is fixedly arranged at the bottom of the car seat and provides basic support for the entire slide rail mechanism 2. The inner rail 211 is slidably arranged in the outer rail 212 and connected with the slide rail driving assembly 22 and can smoothly slide along the extension direction of the outer rail 212 under the action of the slide rail driving assembly 22. The slide rail driving assembly 22 comprises a slide rail driving motor 221 and a slide rail transmission assembly 222. The slide rail driving motor 221 is arranged between the linear slide rails 21 through a mounting bracket. One end of the slide rail transmission assembly 222 is connected with the output end of the slide rail driving motor 221, and the other end is connected with the inner rail 211. When the slide rail driving motor 221 is started, the inner rail 211 slides in the outer rail 212 through the slide rail transmission assembly 222, thereby driving the cushion framework 1 to move in the front-back direction.

[0029] Furthermore, in order to facilitate the installation of the cushion locking mechanism 6 and the locking driving mechanism 5, the front end of the inner rail 211 is fixedly provided with a first cross bar 23, and the rear end is provided with a second cross bar 24. The two ends of the first cross bar 23 are fixedly connected with the upper surface of the inner rail 211, for installing the cushion locking mechanism 6. The two ends of the second cross bar 24 are fixedly connected with the upper surface of the inner rail 211, for installing the locking driving mechanism 5.

The locking pin 61 is fixedly arranged at the bottom end of the cushion framework 1 and is in the shape of L as a whole, for being inserted into and limited in the locking groove 62, so as to realize the locking connection between the cushion framework 1 and the slide rail mechanism 2. The locking groove 62 is arranged on the slide rail mechanism 2, that is, the locking groove 62 is arranged on the first cross bar 23 and is adapted to the locking pin 61, for accommodating the locking pin 61. The locking driving mechanism 5 is connected with the movable end of the locking groove 62, for controlling the movement of the movable end of the locking groove 62, thereby controlling the unlocking and locking of the locking pin 62. Specifically, the locking driving mechanism 5 includes a locking driving motor 51 and a locking cable 52. The locking driving motor 51 is arranged on the slide rail mechanism 2, that is, the locking driving motor 51 is arranged on the second cross bar 24. One end of the cable is connected with the locking driving motor 51, and the other end is connected with the movable end of the locking groove 62, for pulling the locking groove 62 to move under the driving of the locking driving motor 51, so that the locking pin 61 can be separated from the locking groove 62, to realize the separation or locking of the locking pin 61 and the locking groove 62, thereby realizing the disconnection and connection between the cushion framework 1 and the slide rail mechanism 2. That is, under normal use, the locking pin 61 and the locking groove 62 are in locking connection, which ensures the close connection between the cushion framework 1 and the slide rail mechanism 2 and provides stable support. When the seat needs to be stored, the locking pin 61 and the locking groove 62 are disconnected, so that the cushion framework 1 can be separated from the slide rail mechanism 2, thereby facilitating the overturning of the cushion framework 1.

[0030] Further, in order to facilitate the installation of the locking groove 62, the cushion locking mechanism 6 further includes a mounting plate 63. The bottom end of the mounting plate 63 is arranged on the slide rail mechanism 2 on both sides and is hinged with the slide rail mechanism 2. As shown in FIG. 1, the mounting plate 63 is arranged on the slide rail mechanism 2 on both sides, and the two ends of the mounting plate 63 are hinged with the slide rail mechanism 2. The two ends of the mounting plate 63 are hinged with the slide rail mechanism 2, and the locking groove 62 is arranged on the mounting plate 63. The two ends of the mounting plate 63 are hinged with the slide rail mechanism 2, and the locking groove 62 is arranged on the mounting plate 63. Figures 5-6As shown, the bottom end of the mounting plate 63 is provided with a connecting seat 64, one end of the connecting seat 64 is provided with an arc-shaped groove 641 matched with the first horizontal rod 23, the arc-shaped groove 641 is used for connecting with the first horizontal rod 23, and the other end is provided with a torsion spring part 642 hinged with the mounting plate 63, so that the mounting plate 63 can rotate relative to the first horizontal rod 23, and the locking groove 62 is arranged on the mounting plate 63. In order to drive the mounting plate 63 to rotate, the locking driving mechanism 5 further comprises a rotating cable 53, one end of the rotating cable 53 is connected with the cushion driving mechanism 4, and the other end is connected with the mounting plate 63, which is used to drive the mounting plate 63 to rotate from the vertical state to the horizontal state under the driving of the cushion driving mechanism 4.

[0031] As shown in Figure 3 and Figure 7 The cushion driving mechanism 4 comprises a cushion driving motor 41, a cushion driving gear 42 and a cushion transmission toothed plate 43. The cushion driving motor 41 is arranged on the backrest framework 3 and located on the outer side of the backrest framework 3, and the output shaft of the cushion driving motor 41 penetrates through the backrest framework 3; the cushion driving gear 42 is connected with the output shaft of the cushion driving motor 41 and used to rotate under the driving of the cushion driving motor 41. The cushion transmission toothed plate 43 is fixedly arranged at the top end of the cushion framework 1 and engaged with the cushion driving gear 42, and used to move the cushion transmission toothed plate 43 under the driving of the cushion driving motor 41 through the cushion driving gear 42, so as to realize the upward overturning of the cushion framework 1. Exemplarily, the cushion transmission toothed plate 43 is an arc-shaped toothed plate, the arc degree of which is matched with the track of the overturning of the cushion framework 1, so as to ensure that the cushion framework 1 can be smoothly and smoothly overturned upward under the driving of the cushion driving motor 41, and provide convenience for the forward and backward movement of the seat and the subsequent folding and storage operation.

[0032] The backrest framework 3 comprises a framework body 31, a lower connecting plate 32, a backrest adjusting motor 33, an angle adjuster 34 and a transmission shaft 35. The top end of the lower connecting plate 32 is arranged at the bottom end of the framework body 31 and is hinged with the framework body 31, so as to facilitate the angle adjustment of the framework body 31. The backrest adjusting motor 33 is arranged at the inner side of the framework body 31 and is fixed by a motor support, thereby providing a power source for the adjustment of the backrest angle. The angle adjuster 34 is arranged at the inner side of the framework body 31 and is located at the connecting position of the framework body 31 and the lower connecting plate 32, and is connected with the output end of the backrest adjusting motor 33. Preferably, two angle adjusters 34 are arranged symmetrically at the inner side of the framework body 31. The two ends of the transmission shaft 35 are respectively connected with the angle adjusters 34, for synchronously transmitting the rotary power of the backrest adjusting motor 33. When it is needed to adjust the angle or fold the backrest of the framework body 31, the backrest adjusting motor 33 is started to drive the angle adjuster 34 to rotate, and then the rotary power is synchronously transmitted to the two angle adjusters 34 through the transmission shaft 35, so as to realize the angle adjustment of the backrest framework 3 relative to the cushion framework 1, thereby enabling the passenger to adjust to a comfortable sitting posture according to the own needs, or enabling the framework body 31 to be folded to a horizontal state.

[0033] In order to realize the connection of the backrest framework 3 with the cushion framework 1 and the slide rail mechanism 2, the lower connecting plate 32 of the backrest framework 3 is provided with a connecting through hole 321 and a screw hole 322, the top end of the cushion framework 1 is provided with a rotary through hole 11, the hole diameter of the rotary through hole 11 is larger than that of the connecting through hole 321, and the cushion framework 1 is fixed on the backrest framework 3 by a bolt passing through the connecting through hole 321 and the rotary through hole 11. Since the hole diameter of the rotary through hole 11 is larger than that of the connecting through hole 321, the cushion framework 1 can rotate relative to the lower connecting plate 32, thereby facilitating the upward overturning of the cushion framework 1. The screw hole 322 is arranged at the bottom end of the lower connecting plate 32, the inner rail 211 of the slide rail assembly is provided with a mounting hole 25 matched with the screw hole 322, and the screw hole 322 and the mounting hole 25 are screwed, thereby realizing the fixed connection of the backrest framework 3 with the slide rail mechanism 2.

[0034] Further, in order to facilitate the rear passengers to quickly escape in emergency, the car seat with folding storage and emergency escape function further comprises a handhold 7 and an emergency pull cable 8. The handhold 7 is arranged at the top end of the backrest framework 3, which is convenient for the rear passengers to quickly find and operate in emergency. One end of the emergency pull cable 8 is connected with the movable end of the handhold 7, and the other end is connected with the angle adjuster 34. When the rear passengers need to escape in emergency, they only need to pull the handhold 7, the handhold 7 pulls the emergency pull cable 8, the emergency pull cable 8 pulls the angle adjuster 34, and the angle adjuster 34 is quickly unlocked, so that the angle restriction between the framework body 31 and the lower connecting plate 32 in the locked state is released. At this time, the backrest framework 3 quickly flips and folds forward under the pulling force of the passengers, forming a wide emergency escape channel, providing a convenient escape path for the rear passengers, effectively solving the escape problem caused by the narrowness of the conventional channel, and further protecting the life safety of the passengers in emergency.

[0035] Working principle: Seat storage: when the seat needs to be stored to expand the horizontal space or facilitate the passengers to get in and out, first start the locking drive motor 51, the locking drive motor 51 pulls the locking slot 62 through the locking cable 52, so that the locking pin 61 which is originally inserted and limited in the locking slot 62 is separated from the locking slot 62, realizing the disconnection of the seat cushion framework 1 and the slide rail mechanism 2. At this time, the seat cushion framework 1 is in a movable state. Then, start the seat cushion drive motor 41, the seat cushion drive motor 41 drives the seat cushion drive gear 42 to rotate. Since the seat cushion transmission tooth plate 43 is engaged with the seat cushion drive gear 42, and the seat cushion transmission tooth plate 43 is fixedly arranged at the top end of the seat cushion framework 1, the rotation of the seat cushion drive gear 42 will drive the seat cushion transmission tooth plate 43 to move, and then drive the seat cushion framework 1 to flip upward. In the process of the seat cushion framework 1 flipping upward, the rotating cable 53 is pulled, the rotating cable 53 drives the mounting plate 63 to rotate from the vertical state to the horizontal state, thereby completing the preliminary folding storage action, effectively reducing the occupation of horizontal space. After the seat cushion framework 1 flips upward, the slide rail mechanism 2 can be driven by the slide rail drive motor 221 to drive the inner rail 211 to slide forward in the outer rail 212 through the slide rail transmission assembly 222, thereby driving the entire preliminarily folded seat to move forward to adjust the position of the seat, so as to greatly expand the storage space and significantly improve the storage efficiency.

[0036] Folding and emergency escape: when it is necessary to fold or adjust the angle of the backrest, the backrest adjusting motor 33 is started, the backrest adjusting motor 33 drives the angle adjuster 34 to rotate, the rotating power is synchronously transmitted to the two angle adjusters 34 through the transmission shaft 35, the angle adjusters 34 are unlocked, the angle restriction between the skeleton body 31 and the lower connecting plate 32 in the locked state is released, and then the skeleton body 31 can rotate relative to the lower connecting plate 32, the folding of the backrest skeleton 3 is realized, and the storage space is expanded. When the vehicle is involved in water, collision deformation causes power failure or failure, and other emergency situations require escape, at this time, the motor cannot be started, the rear passengers only need to pull the buckle hand 7 arranged at the top end of the backrest skeleton 3, so that the buckle hand 7 pulls the emergency pull rope 8, the emergency pull rope 8 pulls the angle adjuster 34, and then the angle adjuster 34 is quickly unlocked, the angle restriction between the skeleton body 31 and the lower connecting plate 32 is released, so that the backrest skeleton 3 is quickly folded forward under the action of the pulling force of the passengers, forming a spacious emergency escape channel, providing a convenient escape path for the rear passengers, effectively solving the escape problem caused by the narrowness of the conventional channel, and protecting the life safety of the driver and the passenger in the emergency situation.

[0037] In the embodiment, the automobile seat with folding storage and emergency escape function of the application includes a cushion skeleton, a slide rail mechanism, a backrest skeleton, a cushion driving mechanism and a locking driving mechanism. The locking connection (providing stable support for passengers) and disconnection (making the cushion skeleton separate from the slide rail mechanism, facilitating subsequent folding and storage of the cushion skeleton) of the cushion skeleton and the slide rail mechanism are flexibly realized through the cooperation of the cushion driving mechanism and the locking driving mechanism, ensuring the stability of the seat in normal use and the convenience in storage. The cushion skeleton is rotatably arranged on the backrest skeleton, and the cushion driving motor drives the cushion driving gear to rotate and mesh with the cushion transmission gear plate, thereby driving the cushion skeleton to turn upward, creating conditions for the forward and backward movement and storage of the seat. At the same time, by arranging the buckle hand and the emergency pull rope, the rear passengers can pull the buckle hand to drive the emergency pull rope to pull the angle adjuster in an emergency, so that the angle adjuster is quickly unlocked, the backrest skeleton is quickly folded forward under the action of the pulling force of the passengers, forming a spacious emergency escape channel, providing a convenient escape path for the rear passengers, effectively solving the escape problem caused by the narrowness of the conventional channel, and protecting the life safety of the driver and the passenger in the emergency situation. In addition, the arrangement of the buckle hand and the emergency pull rope will not affect the functions of the seat during normal folding and storage of the seat, which not only ensures the comfort and practicality of the seat in normal use, but also plays a key role in escape in emergency, greatly improving the safety and reliability of the automobile seat.
