The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In the prior art, when a vehicle is in 25% offset collision, the front of a driving position in a passenger compartment is directly opposite to a wheel assembly, the wheel assembly is a rigid part, the whole body is difficult to collapse and deform, and when the vehicle is in collision, a frame pushes the whole wheel assembly to enter the passenger compartment, so that the whole body has the problem of low safety. In this scheme, in order to solve the lower problem of security that prior art exists, this scheme provides a tire gassing structure, frame and vehicle, aims at solving prior art, and the vehicle is at the lower problem of the whole security of reply 25% offset collision time, has the higher advantage of structural security, and concrete scheme is as follows:

referring to fig. 1, 2 and 3, the utility model provides a tire deflation structure, which comprises a puncture assembly for movably connecting with a frame. Wherein the piercing assembly comprises a piercing member 10, the piercing member 10 being arranged towards the tyre 31. The puncture assembly is connected with a linkage piece 20, the linkage piece 20 is used for connecting an anti-collision bar 30 or a vehicle frame, and the vehicle frame deforms and collapses under the collision to enable the linkage piece 20 to push the puncture assembly to move, so that the puncture piece 10 is driven to puncture the tire 31.

It should be noted that in this embodiment, the tire deflation structure is integrally applied and mounted on the vehicle, wherein the puncture assembly of the tire deflation structure is connected with the frame. The vehicle frame extrudes the whole wheel in the process of collapsing deformation, and the main function of the tire deflation structure lies in that when the vehicle frame extrudes the wheel, the linkage part 20 can push the whole puncture assembly under the action of impact force, so that the puncture part 10 pierces into the tire 31 of the wheel, therefore, the linkage part 20 needs to be installed at the position ahead of the impact sequence, and the linkage part 20 can be installed on the bumper 30 or the vehicle frame, specifically, in the embodiment, the linkage part 20 is installed on the bumper 30.

Illustratively, when the vehicle frame is collided, the barrier column is firstly contacted with the whole bumper 30 of the vehicle, then the bumper 30 further collides the vehicle frame, the vehicle frame is extruded and deformed by collision, and the vehicle body is gradually decelerated due to energy absorption of collision in the deformation process of the vehicle frame. Since the linking member 20 is mounted on the bumper 30, the bumper 30 drives the linking member 20 to push the whole puncture assembly while the bumper 30 further collides with the vehicle frame, so that the puncture member 10 pierces into the tire 31 of the wheel. As the puncture element 10 penetrates into the tire 31, the high-pressure air inside the tire 31 will gradually leak out, and finally the collision deflation effect is achieved.

Compared with the prior art, during actual collision, in the collapsing deformation process of the frame, the tire deflation structure deflates the tires 31 of the wheels, so that the tires 31 with higher rigidity are deflated to form a soft structure, the effective collision length of the barrier column and the A column of the vehicle is directly increased by 2 inflation height values of the tires 31 in the front and rear direction of the collision, and when the collision continues, the barrier column collides with the A column area through the increased 2 inflation height strokes of the collision tires 31, so that the collapsing deformation stroke and time of the frame are indirectly increased, the speed, the acceleration and the intrusion capacity of the barrier when the barrier collides with the A column are reduced, the effect of protecting a driver during collision is finally achieved, and the safety of the whole structure is greatly improved.

It should be noted that, when the frame suffers the striking, puncture piece 10 pierces into the inside air cavity of tire 31, and the gas in the air cavity can outwards be discharged through the passageway that loses heart fast, improves the gas outgoing efficiency of tire 31, avoids gas outgoing efficiency lower, leads to tire 31 still to have higher rigidity in whole collision process, improves the softening rate of tire 31 structure, further optimizes the collision security of frame through the setting of the passageway that loses heart.

In an embodiment, the puncturing assembly is further detailed, in which the puncturing assembly comprises a mounting base 21, the mounting base 21 is used for rotatably connecting the vehicle frame, one end of the linkage 20 is connected with the mounting base 21, and the puncturing element 10 is arranged on the mounting base 21.

In order to optimize the smoothness of the linkage member 20, in this embodiment, the linkage member 20 is connected to the mounting seat 21 in an articulated manner. The parts are likely to deform irregularly in the process of collision, and the hinged arrangement can avoid the deformation of the linkage piece 20 from influencing the integral rotation of the linkage mounting seat 21, so that the linkage smoothness of the linkage piece 20 is optimized. Specifically, in this embodiment, the linkage 20 includes a mounting plate 201 and a hinge rod 202, wherein the mounting plate 201 is configured to be fixedly mounted on the vehicle frame, and one end of the hinge rod 202 is hinged to the mounting plate 201, and the other end is hinged to the mounting seat 21.

Preferably, in this embodiment, the mounting base 21 is pivotally connected to the frame to define a connection location, and the puncturing element 10 is located on the mounting base 21 on a side thereof remote from the connection location.

It should be noted that the distance between the puncturing element 10 and the connecting position is equivalent to increasing the rotation radius of the puncturing element 10, so that the pushing of the linkage 20 can quickly link the puncturing element 10 to penetrate into the tire 31 of the wheel, and further improve the air discharging and air discharging efficiency of the tire air discharging structure.

Preferably, in this embodiment, the puncturing element 10 is detachably connected to the mounting seat 21 through the external section 102, specifically, a through hole is provided on the mounting seat 21, and the puncturing element 10 is in threaded connection with the through hole on the mounting seat 21, which can facilitate the operator to rotatably couple the tire deflation structure.

In order to understand the features and technical content of the embodiments of the present disclosure more thoroughly, a specific application example is provided below for illustration, and it is understood that the following application example is only used as a reference and does not limit the specific implementation process.

Referring to fig. 1 and 2, the present invention further provides a vehicle frame, including the tire deflation structure mentioned in the above solution.

The frame further comprises a bumper 30, a buffer structure and a wheel assembly 33, wherein the buffer structure comprises a longitudinal beam 32, the wheel assembly 33 is connected with the longitudinal beam 32, and the end part of the longitudinal beam 32 is connected with the bumper 30.

The buffer structure further comprises an A-pillar cavity 34, the A-pillar cavity 34 extends towards the head direction of the frame and is provided with a protection beam 35, and the protection beam 35 is wound outside the wheel assembly 33.

It should be noted that, in this embodiment, the tire deflation structure is provided on the protective beam 35, specifically, the tire deflation structure is located right in front of the protective beam 35 in the vehicle front direction of the wheel assembly 33, wherein the linkage 20 is connected with the bumper 30. Because the whole protective beam 35 is wound around the outside of the wheel assembly 33, when the whole vehicle is collided and deformed, the bumper 30 will contact with the barrier column first, and when the bumper 30 continues to bear the collision, the bumper 30 will be extruded by the barrier column and deformed in the collapsing direction of the vehicle frame, at this time, the movement of the bumper 30 will drive the linkage 20 to push the puncture piece 10 to puncture the tire 31 on the wheel assembly 33, and finally the effect of deflating the tire 31 is realized.

The guard beam 35 is configured to surround the upper half of the wheel assembly 33 and delay the collision sequence of the wheel assembly 33. The rigid structure of the protective beam 35 can increase the stroke of the barrier column which is singly collided and extruded with the vehicle body and the contact collapse time, and improve the integral structural rigidity of the vehicle frame.

More preferably, in this embodiment, an energy absorbing cylinder is disposed outside the protection beam 35, specifically, the energy absorbing cylinder is a first energy absorbing cylinder 40, the first energy absorbing cylinder 40 is located in front of the wheel assembly 33, and the protection beam 35 is connected to the bumper 30 through the first energy absorbing cylinder 40.

The first energy absorbing cylinder 40 can play a role in deformation and buffering of impact, and the first energy absorbing cylinder 40 can firstly protect the impact of the beam 35 on the obstacle column in one step and relieve the speed of the frame. When the frame suffers a small-sized collision with a small speed, the first energy absorbing cylinder 40 can completely relieve the collision force of the frame and reduce the speed of the frame to zero, at the moment, the collision bumper 30 does not collide with the protection beam 35, so that the stroke of pushing the linkage 20 is short, the puncture piece 10 is not in contact with the tire 31, and the puncture piece 10 cannot puncture the tire 31.

In an exemplary 25% offset collision of a vehicle with the frame, the barrier pillars will first contact the bumper 30 of the frame, and then the bumper 30 will impact the side rails 32 and the protective beam 35, the protective beam 35 will be deformed by the crush, and the vehicle body will gradually decelerate due to the energy absorbed by the collision during the deformation of the frame. When the obstacle pillar continues to press against the protection beam 35 via the bumper 30 and further impacts the wheel assembly 33, the movement of the bumper 30 will drive the linkage 20 to push the piercing member 10 to pierce the tire 31 on the wheel assembly 33, thereby deflating the tire 31.

When the obstacle post continues to extrude the whole deformation of frame, tire deflation structure will lose heart to the tire 31 of wheel, make the great tire 31 of rigidity lose heart and become soft structure, so on the fore-and-aft direction of collision, the obstacle post directly increased 2 tire 31 with the effective length of collision of vehicle A post and inflated the height value, when continuing the striking, the obstacle post just collides A post region after the high stroke through 2 collision tire 31 inflation that increase, thereby indirect collapse deformation stroke and the time that has increased the frame, speed when having reduced collision A post, acceleration and invasion ability, protection driver's effect when finally reaching the collision, very improve overall structure's security.

Compared with the prior art, when the vehicle frame is used for coping with 25% or 40% offset collision, the intrusion amount of the barrier column into the inner cab or the inner passenger compartment of the vehicle can be reduced, namely, the impact stroke of two inflation heights on the tire 31 is increased through the deflation of the tire 31, and the whole structure installation performance is high.

In one embodiment, the crash bar 30 is provided with a second energy absorbing tube 41, and the second energy absorbing tube 41 is located right in front of the wheel assembly 33 in the vehicle head direction, and the linkage 20 of the tire deflation structure is fixedly connected with the second energy absorbing tube 41.

It should be noted that, the second energy-absorbing cylinder 41 is matched with the first energy-absorbing cylinder 40, so that the crash bar 30 and the linkage member 20 can have a primary anti-collision performance, when the frame is subjected to a small collision with a low speed, the first energy-absorbing cylinder 40 and the second energy-absorbing cylinder 41 can completely relieve the collision force of the frame, and the speed of the frame is reduced to zero, at this time, the longitudinal beam 32 and the linkage member 20 will not be further impacted by the crash bar 30, so as to prevent the small touch, i.e. triggering the tire deflation structure to puncture the tire 31 of the wheel assembly 33, and further improve the collision buffering performance of the frame structure.
