Description

Technical Field

[0001] The invention relates to the technical field of vehicle seat safety, and in particular to an impact trigger device for an occupant seat and an electric safety neck support assembly. Background Art

[0002] The passenger seats of vehicles are often not equipped with neck supports, resulting in poor passenger comfort. The reason is that when the vehicle collides, the passenger's head is easily whipped, resulting in neck injuries. When the vehicle is hit from behind, the passenger's head moves backward rapidly. At this time, if a neck support is provided, the whipping effect will be aggravated, aggravating the neck injury. In addition, when the vehicle is hit from the front, there is also the possibility that the passenger's head moves backward rapidly due to the explosion of the airbag or the rebound of the seat belt, causing the whipping effect. At this time, if a neck support is provided, the whipping effect will be aggravated.

[0003] There is no solution to this problem in the industry at present, and the only solution is to not provide neck support based on the principle of safety first. Therefore, when sitting in the passenger seat of a vehicle, the comfort of the passenger needs to be improved due to the lack of neck support. For this reason, we propose an impact trigger device for the passenger seat and an electric safety neck support assembly. Summary of the invention

[0004] The purpose of the present invention is to solve the problems mentioned in the above background technology. The present invention provides an impact trigger device for an occupant seat and an electric safety neck support assembly.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] An impact triggering device for a passenger seat, comprising:

[0007] A base, the base is connected to the seat frame and is provided with a plurality of holes;

[0008] A connecting rod, wherein a plurality of holes are provided on the connecting rod, and the connecting rod can be connected to other connecting rods or components through a connecting piece;

[0009] A driving device, the driving device is arranged on the base or the seat frame, and the driving device is connected to a driven wheel;

[0010] A driven shaft, the driven shaft is arranged on the base and connected to the driven wheel;

[0011] A locking device, wherein the locking device is arranged on the driven shaft and connected to the connecting rod;

[0012] An impact trigger device, wherein the impact trigger device is arranged on a base or a driven shaft;

[0013] A reset device, wherein the reset device is connected to the base and is connected to a long shaft, wherein the long shaft and one group of the connecting rods form a whole, and the reset device has a built-in spring, and one end of the spring is connected to the base, and the other end can be connected to any of the connecting rods, or the core shaft, or the neck support, or the driven shaft.

[0014] Furthermore, the driving device is built with a worm gear meshing structure.

[0015] Furthermore, the driving device comprises a motor, the motor is connected to a pull rope, the pull rope is wound around the driven wheel, and a pull rope clamp is installed on the driven wheel.

[0016] Furthermore, the locking device includes a sliding block, a sliding groove is provided in the locking device, a sliding block is provided on the sliding block, the sliding block is arranged in the sliding groove, an engaging groove is provided on the sliding block, an engaging block is provided on the driven shaft, the engaging block is arranged in the engaging groove, and an elastic element connected to the sliding block is provided on the driven shaft.

[0017] Furthermore, a trigger device housing is arranged on the outer side of the impact trigger device.

[0018] Furthermore, the impact trigger device includes: an electromagnet, and the electromagnet is arranged on the base or on the driven shaft.

[0019] Furthermore, the impact trigger device includes: a trigger motor, a rotating paddle installed above the trigger motor, a rotating connecting rod installed above the rotating paddle, an inertial body arranged inside the trigger device housing, a trigger device shell mounting hole opened in the trigger device housing, a coil spring installed on the left circumferential surface of the driven shaft, a rotating paddle shaft installed on the rotating paddle, and a driven shaft mounting hole opened inside the rotating paddle.

[0020] An electric safety neck support assembly comprises any of the impact trigger devices described above; and a neck support body, a neck support base plate installed on the rear side of the neck support body, and the neck support base plate is connected to the connecting rod.

[0021] Furthermore, a slide rail is provided on the bottom plate of the neck support, a slider is provided in the slide rail, and the slider is connected to the connecting rod.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. When the present invention is in normal use, the movement of the driving device is controlled by the vehicle computer interactive signal to adjust the position of the neck support body. When the position of the neck support body needs to be adjusted forward, the driving device can drive the driven shaft to rotate through the locking device, and the rotation of the driven shaft causes the connecting rod to move, thereby causing the neck support body to move. When it is necessary to maintain the extended position, the motor in the driving device stops rotating, and the worm gear mechanism in the driving device can continue to maintain the force on the driven shaft, so that the connecting rod remains locked and the neck support body remains in the extended position. When the position of the neck support body needs to be adjusted backward, the driving device drives the driven wheel to rotate in the opposite direction, and under the action of the driving device and the reset device, the neck support body moves backward.

[0024] 2. In the embodiment of the present invention in which a pull cord is provided in the driving device when the neck support moves backward, the driving shaft is driven by the pull cord, so the driving can only provide a force for forward adjustment, and the backward movement is mainly achieved by the reset device. The force of the reset device is relatively small, which can play an anti-pinch effect. A certain angle is set at the place where the bite block on the driven shaft and the sliding block in the locking device bite, so that they can be disengaged when overloaded, which plays an effect of preventing pinching caused by overload. Therefore, the neck support body supports the neck of the occupant and improves riding comfort.

[0025] 3. In the present invention, when a vehicle is subjected to an impact above a certain level, the impact force is transmitted from the passenger seat to the impact trigger device of the vehicle passenger seat and the electric safety neck brace assembly, so that the impact trigger device is triggered. Under the action of the impact trigger device, the locking effect of the locking device is released, and the neck brace bottom plate and the neck brace main body are quickly retracted under the pulling force of the reset device, thereby canceling the supporting force of the neck brace main body on the occupant's neck, avoiding the aggravation of the whiplash effect, protecting the safety of the passengers, and achieving the effect of improving the riding comfort of the passengers under the premise of safety.

[0050] The reset device 12 is connected to the base 1, and the reset device 12 is connected to a long shaft 18, and the long shaft 18 forms a whole with one set of connecting rods 2. The reset device 12 has a built-in spring, and one end of the spring is connected to the base 1, and the other end can be connected to any connecting rod 2, or the core shaft, or the neck support, or the driven shaft 10.

[0051] An electric safety neck collar assembly, comprising any of the above-mentioned impact triggering devices; and,

[0052] The neck support body 4 is connected to the connecting rod 2 , and a neck support base plate 3 is arranged on the rear side of the neck support body 4 , a slide rail 17 is arranged on the neck support base plate 3 , and a slider 7 is arranged in the slide rail 17 , and the slider 7 is connected to the connecting rod 2 .

[0053] Embodiment 1

[0054] like Figure 2AAs shown, the base 1 is connected to the seat frame, a plurality of holes are provided on the base 1, and a slide rail 17 is provided on the base 1; a plurality of holes are provided on the connecting rod 2, and the connecting rod 2 can be connected to other connecting rods or components through a connecting piece; the slider 7 is connected to the connecting rod 2, and the slider 7 is arranged in the slide rail 17; the driving device 5 is arranged on the base 1, and the driving device 5 is connected to the driven wheel 11; the driven shaft 10 is arranged on the base 1, and the driven shaft 10 is connected to the driven wheel 11; the locking device 9 is arranged on the driven shaft 10, and the locking device 9 is connected to the connecting rod 2; the impact trigger device 8 is connected to the locking device 9.

[0055] Specifically, the driving device 5 has a built-in worm gear meshing structure.

[0056] Specifically, the driving device 5 includes a motor 16 , the motor 16 is connected to a pull rope 14 , the pull rope 14 is wound around a driven wheel 11 , and a pull rope clamp 15 is installed on the driven wheel 11 .

[0057] Specifically, the locking device 9 includes a sliding block 6, a sliding groove 24 is provided in the locking device 9, a sliding block 25 is provided on the sliding block 6, the sliding block 25 is arranged in the sliding groove 24, an engaging groove 26 is provided on the sliding block 6, an engaging block 27 is provided on the driven shaft 10, the engaging block 27 is arranged in the engaging groove 26, and an elastic element 13 connected to the sliding block 6 is provided on the driven shaft 10.

[0058] Specifically, the elastic element 13 is disposed on the driven shaft 10 .

[0059] Specifically, the impact trigger device 8 is an electromagnet. When the vehicle is impacted, the electromagnet of the impact trigger device 8 is energized, sucking the sliding block 6 to move toward the impact trigger device 8, so that the bite groove 26 on the sliding block 6 and the bite block 27 on the driven shaft 10 are loosened, and the locking device 9 is unlocked. At this time, the connecting rod 2 and the driven shaft 10 are no longer locked with each other. Under the action of the reset device 12, the long shaft 18 is pulled back, and the connecting rod 2 moves, so that the neck support base plate 3 and the neck support body 4 are retracted, so as to realize the function of quickly canceling the support force on the occupant's neck when impacted.

[0060] The working principle and use process of the present invention are as follows: when the neck support body 4 needs to be adjusted forward of the occupant, the occupant controls the motor 16 in the driving device 5 to rotate through the vehicle computer interactive signal, and the motor 16 drives the pull rope 14 to drive the driven wheel 11 to rotate, so that the driven shaft 10 rotates. Due to the action of the elastic element 13, the bite block 27 on the driven shaft 10 bites with the bite groove 26 on the sliding block 6, so the sliding block 6 rotates with the driven shaft 10, and the sliding block 25 on the sliding block 6 and the sliding groove in the locking device 9 are engaged. 24 is connected, and the locking device 9 is connected to the connecting rod 2, so the locking device 9 and the connecting rod 2 rotate with the driven shaft 10. Under the action of the plurality of connecting rods 2 and the slider 7, the neck support base plate 3 and the neck support body 4 move forward along a specific trajectory relative to the base. When the state of the neck support body 4 needs to be maintained, the motor 16 in the driving device 5 stops rotating. The driving device 5 has a worm gear mechanism to achieve self-locking, so that the neck support base plate 3 and the neck support body 4 cannot move toward the rear of the occupant, so as to provide support for the occupant's neck.

[0061] When it is necessary to adjust the neck support body 4 toward the rear of the occupant, the motor 16 in the driving device 5 rotates in the other direction, so that the pull rope 14 becomes relatively loose. Under the elastic force of the reset device 12, the neck support base plate 3 and the neck support body 4 are pulled toward the rear of the occupant. Since the elastic force of the reset device 12 is relatively small, it can also play an anti-pinch protection effect.

[0062] In addition, because the engaging groove 26 and the engaging block 27 are both provided with inclined surfaces at a certain angle, when the force is too large, the inclined surfaces of the engaging groove 26 and the engaging block 27 slide relative to each other, causing the engaging groove 26 of the sliding block 6 and the engaging block 27 of the driven shaft 10 to overcome the elastic force of the elastic element 13 and separate, thereby preventing pinching and excessive force.

[0063] When impacted, after receiving the collision signal, the vehicle controller sends a command to trigger the impact trigger device 8. The electromagnet in the impact trigger device 8 is energized to generate a magnetic field to attract the sliding block 6, so that the sliding block 6 engagement groove 26 and the engagement block 27 of the driven shaft 10 overcome the elastic force of the elastic element 13 and disengage, thereby releasing the locking effect of the locking device 9. At this time, the sliding block 6 can rotate relative to the driven shaft 10, that is, the connecting rod 2 can rotate. Under the action of the resetting device 12, the neck support base plate 3 and the neck support body 4 move quickly to the rear of the occupant to a retracted state to avoid supporting the occupant's neck during impact and increasing the risk of neck injury.

[0069] like Figure 2E As shown, a triggering device housing 19 is arranged on the outer side of the impact triggering device 8 .

[0070] Specifically, the impact trigger device 8 includes: a trigger motor 22, a rotating paddle 20 installed above the trigger motor 22, a rotating connecting rod 21 installed above the rotating paddle 20, an inertial body 28 arranged inside the trigger device housing 19, a trigger device housing mounting hole 29 opened in the trigger device housing 19, a coil spring 23 installed on the left circumferential surface of the driven shaft 10, a rotating paddle shaft 30 installed on the rotating paddle 20, and a driven shaft mounting hole 31 opened inside the rotating paddle 20.
