Description
Technical Field
[0001] The present invention relates to the technical field of vehicle seat safety, and in particular to an impact triggering method and device. 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 prone to whiplash, resulting in neck injuries. Specifically, when the vehicle is impacted from the rear, the passenger's head moves backward rapidly. At this time, if a neck support is provided, the head will move more relative to the shoulder and cervical spine, which will aggravate the whiplash effect and aggravate the neck injury. In addition, when the vehicle is impacted 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, resulting in a whiplash effect. At this time, if a neck support is provided, the whiplash 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 triggering method and device. Summary of the invention

[0036] A mounting seat connected to a seat frame or a seat neck support mechanism;
[0037] A trigger device, wherein the trigger device is provided with a sensing device;
[0038] The action device is connected to the trigger device.
[0039] Example 1
[0040] Please refer to Figure 1A and Figure 1B The trigger device includes a sensor and a controller, the action device includes a core shaft Ⅰ1 and a motor 2, a motor mounting seat 4 is installed on the upper end of the motor 2, the motor mounting seat 4 is arranged on the core shaft Ⅰ1, a wire Ⅰ3 is provided on the motor 2, a motor rotating block 8 is installed on the upper end of the motor shaft 7 of the motor 2, a connecting rod Ⅰ9 is installed inside the motor rotating block 8, a sliding block Ⅰ6 is provided on the core shaft Ⅰ1, the sliding block Ⅰ6 can slide along the core shaft Ⅰ1, a spring Ⅰ5 is provided between the motor mounting seat 4 and the sliding block Ⅰ6, the sliding block Ⅰ6 is connected to the locking mechanism of the neck support device, and the movement of the sliding block Ⅰ6 can release the locking effect of the locking mechanism in the neck support device.
[0041] Specifically, the motor rotating block 8 is provided with two shaft holes, and the shaft on the connecting rod I9 is inserted into the shaft holes.
[0042] When the whole is impacted or is about to be impacted, the sensor sends out a collision warning signal or a collision signal. After receiving the collision warning signal or the collision signal, the controller sends out an action command to drive the action device. The motor 2 in the action device rotates, and the connecting rod Ⅰ9 is pulled by the motor rotating block 8, thereby causing the sliding block Ⅰ6 to move, so that the neck support device is unlocked.
[0043] When resetting is required, the motor 2 is reversed by a certain angle, and the motor rotating block 8 pushes the connecting rod Ⅰ9, so that the sliding block Ⅰ6 moves in the opposite direction to achieve resetting. The sliding block Ⅰ6 can also be reset by releasing the power of the motor 2 under the elastic force of the spring Ⅰ5.
[0044] Example 2
[0045] Please refer to the attached Figure 1B to Figure 2The trigger device includes a sensor and a controller, and the action device includes a core shaft Ⅱ21 and an electromagnet 22. The electromagnet 22 is arranged on the core shaft Ⅱ21, and a wire Ⅱ23 is arranged on the electromagnet 22. A sliding block Ⅱ26 is arranged on the core shaft Ⅱ21, and a disc 25 is arranged on the sliding block Ⅱ26. A spring Ⅱ24 is arranged between the electromagnet 22 and the disc 25.
[0046] When the whole is impacted or about to be impacted, the sensor sends out a collision warning signal or a collision signal. After receiving the collision warning signal or the collision signal, the controller sends out an action command to drive the action device. The electromagnet 22 in the action device is energized and pulls the disk 25 through the magnetic field, thereby moving the sliding block II 26 and unlocking the neck support device.
[0047] When resetting is required, the electromagnet 22 is powered off, and the sliding block Ⅰ6 is pushed to reset under the elastic force of the spring Ⅰ5.
[0048] Example 3
[0049] Please refer to the attached FIG. 3A to FIG. 3C The trigger device includes a ball 312, and the action device includes a core shaft III 31 and a shell 32. The shell 32 is arranged on the core shaft III 31, and the ball 312 is arranged in the shell 32. A fixed shaft 34 is provided on the shell 32, and a rotating piece 39 is connected to the fixed shaft 34. A rotating piece pushing block 310 is provided on the rotating piece 39. The rotating piece pushing block 310 is arranged on the shell 32, and the rotating piece 39 is connected to a torsion spring 311. A sliding block III 36 is installed on the core shaft III 31, and a sliding block pulling shaft I 37 is provided on the sliding block III 36. A connecting rod II 33 is arranged below the rotating piece 39, and a connecting rod rotating shaft 35 is provided on the connecting rod II 33. A sliding block pull ring I 38 is installed on the upper end of the sliding block pulling shaft I 37.
[0050] Specifically, a notch is formed on the shell 32 , and the rotating piece pushing block 310 is disposed on the notch.
[0051] Specifically, the rotating piece 39 is provided with an axial hole, and the connecting rod rotating shaft 35 is inserted into the axial hole.
[0052] When the whole is impacted, the ball 312 moves forward or backward relative to the shell 32 due to inertia, hits the side of the rotating plate pushing block 310, pushes the rotating plate 39, and causes the rotating plate pushing block 310 to move by overcoming the force of the torsion spring 311. Therefore, the rotating plate 39 rotates, thereby pulling the sliding block pulling shaft I37 through the connecting rod II 33, causing the sliding block III 36 to move, so that the neck support device is unlocked.
[0053] When resetting is required, the ball 312 returns to the bottom of the V-shaped inner cavity of the housing 32 due to gravity, and the rotating piece 39 moves in the opposite direction under the elastic force of the torsion spring 311, so that the connecting rod II 33 moves and pushes the sliding block III 36 to reset.
[0054] Example 4
[0055] Please refer to the attached FIG. 4A to FIG. 4B The trigger device includes a core shaft IV 41 and an inertia block 42, and the action device includes a rotating sleeve 43.

A spring III 46 is installed between the sliding block IV 45 and the rotating sleeve 43.
[0056] When the whole is impacted, the inertia block 42 swings forward or backward relative to the core shaft IV 41 due to inertia, and the rotating sleeve 43 rotates around the core shaft IV 41 through the connecting rod 49, so that the V-shaped groove 410 rotates relative to the sliding block pulling shaft II 47. Under the action of the inclined surface of the V-shaped groove 410, the sliding block pulling shaft II 47 climbs from the bottom of the V-shaped groove 410 along the inclined surface of the V-shaped groove 410, pulling the sliding block IV 45 to overcome the elastic force of the spring III 46 and move, so that the neck support device is unlocked.
[0057] When resetting is required, the inertia block 42 returns to its original position due to gravity, and the sliding block IV 45 moves under the elastic force of the spring III 46 , and the sliding block pulls the shaft II 47 to move to the bottom of the V-shaped groove 410 to achieve resetting.
[0058] An impact triggering method is provided, and the method is based on any of the above-mentioned impact triggering devices. When a vehicle is impacted or is about to be impacted, the triggering device is triggered. Under the action of the triggering device, an action mechanism moves axially, so that the locking device of the automobile neck support mechanism is released, thereby instantly canceling the supporting force of the neck support body on the occupant's neck.
