3 effectively rupture.
In technique scheme, as it is shown in fig. 7, described balancing weight 10 is arranged in counterweight sleeve 17,
Counterweight sleeve 17 is fixed on counterweight sleeve 17 bottom on body platform 2 and is provided with spring 18, balancing weight 10
It is arranged on spring 18, and holddown spring 18 bottom balancing weight 10, described flexible axle 9 is through counterweight set
The top board of cylinder 17 connects balancing weight 10.Spring 18 has certain pre-pressing amount, it is ensured that car body be not subject to
During to greater impact,
In the present invention, seat under normal usage, hangs solid by two hooks above backrest 1.1
Fixed, seat 1.2 is connected with body roof 6 by drawstring 7 on seat, and beam is fixed by vehicle body in bottom
16 are fixed on body platform 2.As described in Figure 4, seat body 1 is fixed in by four lock pins 3
Vehicle body is fixed on beam 16, and vehicle body is fixed beam 16 and is fixed on body platform 2, and the fracture of lock pin 3 is former
Reason is as shown in Fig. 56, and at normal condition, balancing weight 10 is spacing by counterweight sleeve 17 and spring 18,
Counterweight sleeve 17 is fixed on body platform 2, and spring 18 is in pre-pressing state, has certain compression
Power, it is ensured that in the normal and transport condition of the limit, balancing weight 10 will not produce with counterweight sleeve 17
Relative displacement.When Rhizoma Anemones flaccidae explosion time below body platform 2, car body moment is by acceleration upwards.
Now, the acceleration that fixing with vehicle body counterweight sleeve 17 is subject to is identical with car body.Balancing weight 10 by
In the effect of inertia, instant of detonation acceleration is 0, so balancing weight 10 is relative to being fixed on car body
The acceleration that relative acceleration is explosion time of counterweight sleeve 17, now spring 18 is compressed, and joins
Pouring weight 10 pulls the relative car body of flexible axle 9 to move downward, and then pulls lock pin 3, and lock pin 3 breaks with vehicle body
Open and be rigidly connected.In order to prevent unlocking mechanism response to lose efficacy, increase by the second set unlocking structure (flexible axle 9
Disconnection with lock pin 3).By two grades of unlocking structures, it is ensured that buffering effect, lock pin 3 uses plastic latch
Pin, it is ensured that disconnect when the occupant of setting body weight is by certain acceleration.When Rhizoma Anemones flaccidae is at underbody explosion time,
Exceeding human body and bear the acceleration of the limit when passing to car body, four lock pins 3 unlock, and seat is by up and down
Drawstring is held, and relies on drawstring will be rigidly connected and become flexibly connecting, thus protects human body not to be hit ripple
Injury.The reasonable in design of the present invention, can effectively ensure that occupant safety, and practicality is good.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention not office
Being limited to this, any those of ordinary skill in the art, can be light in the technical scope that disclosed herein
The change being readily conceivable that or replacement, all should contain within protection scope of the present invention.Therefore, the present invention
Protection domain should be as the criterion with the protection domain that claims are limited.
