Description

Technical Field

[0001] The present application relates to the technical field of automobile seats, and in particular to an automobile seat. Background Art

[0002] Car seats are seats for passengers when riding in a car. Car seats need to provide drivers and passengers with easy-to-operate, comfortable and safe driving and riding positions.

[0003] Most existing car seats only have adjustment functions, which can meet the requirements of people's comfortable riding. However, the seats cannot be moved after adjustment. When a car accident occurs, the huge inertia can easily cause the front part of the vehicle (i.e. the steering wheel and the deformed vehicle frame) to collide with the driver's body, causing injury to the driver.

[0004] The patent with the patent authorization announcement number CN110606009B discloses a method for protecting automobile seats from collision. The seat to which the method is applied includes a seat plate, a support plate and a head cushion; a backrest is fixedly connected to the rear end surface of the seat plate; a head cushion is installed on the upper end surface of the backrest; a base is fixedly connected to the lower surface of the seat plate; a first airbag is fixedly connected to the inside of the blocking armrests on both sides of the seat plate; a second airbag is symmetrically fixedly connected to the inside of the backrest on both sides; a third airbag is fixedly connected to the side surface of the backrest facing away from the seat plate; a fourth airbag is fixedly connected to the opposite sides of the two bases; a same neck protection airbag is fixedly connected to the front end surface between the backrest and the head cushion; the present invention effectively solves the inertial damage to passengers in car accidents, effectively protects the neck, reduces the burden on the legs, and can suppress the fire source, providing effective time guarantee for the transfer of passengers, and has high practicality.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] like Figure 1-Figure 3 As shown, a car seat proposed in one embodiment of the present application includes: A seat 1, a backrest 2 is hingedly mounted on the seat 1, armrests 201 are fixedly connected to both sides of the backrest 2, the upper ends of the armrests 201 are detachably connected to shoulder armrests 202, the upper end of the backrest 2 is detachably connected to a neck block 203, and the upper end of the neck block 203 is fixedly connected to a headrest 204; The movable member 3 comprises two parallel slide rails 301, two slide frames 302 slidably matched with the slide rails 301 are fixedly connected to the bottom of the seat 1, and mounting frames 303 are slidably arranged along the length direction of the two slide rails 301 on the opposite sides thereof, and a stopper 304 for clamping and fixing the slide frame 302 is arranged in the mounting frame 303, and an adjusting member 305 for adjusting the position of the mounting frame 303 is arranged on the slide rail 301, and the positions of the mounting frame 303 and the stopper 304 can be adjusted as a whole by setting the adjusting member 305, thereby changing the relative sliding distance between the slide frame 302 and the slide rail 301, so as to increase or decrease the adjustable range of the position of the seat 1 and increase the flexibility of the device; The trigger pusher 4 includes a cylinder 401 fixedly connected to the sliding frame 302, a push rod 402 is slidably installed in the cylinder 401, and the opposite ends of the cylinder 401 and the push rod 402 are fixedly connected to the opposite ends of the sliding frame 302 and the sliding rail 301 respectively. An explosion generator 403 is fixedly connected to the bottom of the cylinder 401, and a shunt pipe 404 located between the explosion generator 403 and the push rod 402 is fixedly connected to one side of the cylinder 401. It should be noted that the explosion generator 403 is similar to the existing vehicle airbag triggering device. The same, both use collision sensors to trigger the inflation system, so that burning sodium nitride will quickly generate a large amount of nitrogen, and the gas is used to push the push rod 402 in the cylinder 401 to move toward one end of the slide rail 301, which is set toward the front end of the car, thereby resisting the slide frame 302 to move toward the other end of the slide rail 301, which is set toward the rear end of the car, so as to push the seat 1 away from the front end parts of the car, ensure the driver's safety space, reduce the risk of the driver colliding with the front end parts of the vehicle due to inertia, and increase the safety of the device; The ventilation expansion bag 5 is installed on the opposite ends of the shoulder armrest 202 and the neck block 203. The ventilation expansion bags 5 are interconnected through a shunt pipe 404. The ventilation expansion bag 5 is installed on the side edge of the shoulder armrest 202 facing the front end of the vehicle. The whole is in the shape of a sheet and is used to wrap the two sides of the driver's body to prevent the flying fragments generated by the collision on both sides from causing harm to the personnel, thereby increasing safety. The ventilation expansion bag 5 on the neck block 203 is rectangular as a whole and is arranged on the side facing the rear end of the vehicle, which is used to block and cushion the rear passengers to avoid hard collisions with the rear passengers when the seat 1 moves backward, thereby further increasing safety. It should be noted that the ventilation expansion bag 5 is connected to the cylinder 401 through the shunt pipe 404, so that part of the gas generated by the explosion generator 403 can be rushed into the ventilation expansion bag 5 to disperse the airflow and avoid the cylinder 401 from exploding due to excessive air pressure.

[0023] like Figure 6 and Figure 8As shown, in some embodiments, two damping inserts 2011 are installed at the upper ends of the armrest 201 and the backrest 2, the bottom of the shoulder armrest 202 is connected with an insert rod 2012 which is inserted into the damping insert 2011, and the bottom of the neck block 203 is constructed with an insert column 2031 which is inserted into the damping insert 2011. The shoulder armrest 202 and the arm armrest 201, as well as the neck block 203 and the backrest 2 are arranged to be detachably connected, so as to facilitate their overall replacement, so as to facilitate the maintenance and replacement of the ventilation expansion bag 5 therein, thereby increasing the convenience of the device. At the same time, the detachable structure adopts the damping insert 2011, which is a cylindrical structure with a socket at one end. When the insert rod 2012 is inserted therein, the air needs to be squeezed out slowly, so the insert rod 2012 will not be easily pulled out, thereby preventing the shoulder armrest 202 and the neck block 203 from falling off easily in the event of a traffic accident, thereby increasing the safety of the device.

[0024] like Figure 3-Figure 4 As shown, in some embodiments, the slide rail 301 is U-shaped and has a stop block 3011 at both ends, the slide frame 302 is n-shaped and has a support block 3021 at one end, a guide bar 3012 is constructed on the inner wall of the slide rail 301, and a guide groove 3022 that slides with the guide bar 3012 is constructed on the outer wall of the slide frame 302, one end of the cylinder 401 is fixedly connected to the support block 3021, and the U-shaped slide rail 301 and the n-shaped slide frame 302 opening are arranged opposite to each other to form a sliding fit, and the guide bar 3012 and the guide groove 3022 are both arranged in the middle, which are used to slide and guide the slide frame 302 while also being used to limit it, so as to prevent the slide frame 302 from easily leaving the slide rail 301 and increase safety.

[0025] like Figure 3-Figure 5As shown, in some embodiments, a plurality of through slots 3013 are arrayed along the length direction of the slide rail 301, a plurality of snap-in slots 3023 for communicating with the through slots 3013 are configured on the side of the slide frame 302 along the length direction thereof, the position-limiting member 304 comprises a flip shaft 3041 that movably penetrates the mounting frame 303, an L-shaped snap-in plate 3042 is configured in the middle of the flip shaft 3041, which is located in the mounting frame 303 and sequentially penetrates the through slots 3013 and the snap-in slots 3023, a return torsion spring 3043 is connected between one end of the flip shaft 3041 and the mounting frame 303, and a spring 3043 is provided between the two slide rails 301. A driving member 6 is provided for synchronously driving the two flip shafts 3041 to rotate. When the position of the sliding frame 302 needs to be adjusted, it is only necessary to synchronously rotate the two flip shafts 3041 through the driving member 6 to drive the L-shaped clamping plate 3042 to disengage from the clamping groove 3023, and then release the limit on the sliding frame 302 to facilitate its movement. When the position of the sliding frame 302 needs to be fixed, it is only necessary to release the control of the flip shaft 3041, and the reset torsion spring 3043 can push it to rotate and reset, so that the L-shaped clamping plate 3042 can be reinserted into the clamping groove 3023 to fix the position.

[0026] like Figure 4-Figure 5 As shown, in some embodiments, the driving member 6 includes a mounting plate 601 fixedly connected to one side of the slide rail 301, one of the flip shafts 3041 rotates and passes through the mounting plate 601 and has a handle 602 fixedly connected to the end thereof, an extension plate 603 is constructed in the middle of the two flip shafts 3041, and a steel wire rope 604 is connected between the two extension plates 603. It should be noted that the extension plate 603 on the flip shaft 3041 connected to the handle 602 is horizontally arranged, while the extension plate 603 on the other flip shaft 3041 is inclined upwardly arranged, and the steel wire rope 604 between the two is in a taut state. When a person pushes the handle 602, not only one of the flip shafts 3041 will be driven to rotate, but also the extension plate 603 will be driven to flip, thereby pulling the extension plate 603 on the other flip shaft 3041 to flip downward through the steel wire rope 604, thereby driving the flip shaft 3041 to rotate, so as to synchronously drive the two L-shaped clamping plates 3042 to disengage from the clamping groove 3023, and the operation is convenient and quick.

[0027] like Figure 5As shown, in some embodiments, the adjusting member 305 includes a connecting plate 3051 fixedly connected to the side of the slide rail 301, a screw rod 3052 is rotatably installed between the connecting plate 3051 and the mounting plate 601, the mounting frame 303 is threadedly engaged with the screw rod 3052, one end of the screw rod 3052 rotates through the mounting plate 601 and a hexagonal slot 3053 is constructed at the end, and the mounting frame 303 can be threadedly engaged with it by rotating the screw rod 3052, thereby changing the position of the mounting frame 303. At this time, the reset torsion spring 3043 is stretched or contracted and can still generate a reset torque on the flip shaft 3041, so that the mounting frame 303 can change its relative position with the sliding frame 302, so as to adjust the maximum moving distance of the sliding frame 302, thereby increasing the flexibility and adaptability of the device.

[0028] like Figure 3 As shown, in some embodiments, the push rod 402 includes a piston block 4021 slidably installed in the cylinder 401, one end of the piston block 4021 is fixedly connected to a slide rod 4022 that movably penetrates the opening of the cylinder 401 and is fixedly connected to the stopper 3011, and the side of the cylinder 401 is configured with a vent hole 4011 arranged near its opening. When the piston block 4021 abuts against the open end of the cylinder 401, the vent hole 4011 is located between the piston block 4021 and the explosion generator 403. It should be noted that in the initial state, the vent hole 4011 and the explosion generator 403 are located on both sides of the piston block 4021, and the shunt pipe 404 is located between the piston block 4021 and the explosion generator 403. The sliding frame 302 The push-pull movement generated by the push rod 402 during movement can generate gas flow through the shunt pipe 404 to ensure the smooth movement of the push rod 402, thereby ensuring that the cylinder 401 always moves with the sliding frame 302. Compared with the push rod 402 not being connected to the slide rail 301, it is safer and can avoid the push rod 402 colliding with the end of the slide rail 301 in the event of a car accident, thereby preventing damage to the device. The air leakage hole 4011 can be connected to the inside of the cylinder 401 where the explosion generator 403 is located when the push rod 402 moves to the end of the cylinder 401, thereby accelerating the discharge of gas and avoiding the explosion of the cylinder 401 due to excessive air pressure, thereby further increasing the safety of the device.

[0029] like Figure 7As shown, in some embodiments, a protective member 7 for limiting the moving distance of the seat 1 is also included. The protective member 7 includes a U-shaped block 701 fixedly connected to the end of the seat 1 and located below the seat back 2. A trigger airbag 702 is installed on the concave side of the U-shaped block 701. The setting of the U-shaped block 701 can limit a certain distance of the seat 1 when a car accident occurs. When the seat 1 moves toward the rear of the vehicle, the U-shaped block 701 will first contact the rear seat. At this time, the U-shaped block 701 will wrap and protect the legs of the rear occupants to prevent them from being hit by the seat 1. At the same time, the gas generated by part of the explosion generator 403 is used to inflate the trigger airbag 702. In conjunction with the ventilation expansion bag 5 on the neck block 203, the impact force of the rear occupants and the seat 1 due to inertia can be buffered, thereby further increasing safety.

[0030] like Figure 7 As shown, in some embodiments, the ventilation expansion bag 5 has the same structure as the trigger airbag 702, and both include a storage frame 501 connected to the shoulder armrest 202, the neck block 203 and the U-shaped block 701, the shunt pipe 404 is connected to the multiple storage frames 501, one side of the storage frame 501 is open and the open end is connected to an elastic sealing sheet 502, the storage frame 501 is connected to a bag 503, and the bag 503 is configured with multiple exhaust holes 504 on the side facing the storage frame 501, initially the elastic sealing sheet 502 is in a state of covering the storage frame 501, and only one side edge thereof is connected to the storage frame 501, and the bag 503 is folded inside the storage frame 501, when the explosive generator 403 is triggered, the elastic sealing sheet 502 will be easily pushed open by the bag 503, so as to ensure the smooth expansion of the bag 503.

[0031] like Figure 3 As shown, in some embodiments, a flexible retractable cloth 8 is connected between the ends of the slide rail 301 and the slide frame 302 for covering the upper opening of the slide rail 301, and a buffer block 10 is connected to one end of the inner part of the slide rail 301 through a support spring 9. The support spring 9 and the buffer block 10 can buffer the impact force of the slide frame 302 to avoid a hard collision between the slide frame 302 and the slide rail 301 when the explosion generator 403 moves backward rapidly after the explosion generator 403 is triggered, thereby ensuring safety. The flexible retractable cloth 8 can be provided to wrap and protect the part to prevent external debris from falling into it and thereby blocking the movement of the slide frame 302.
