"inner and outer" refer to the inner and outer of the outline of the corresponding structure, and "distal and proximal" refer to the distance and proximity from the corresponding structure. Furthermore, the terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

When a vehicle collides or is about to collide, if the vehicle body is lifted, namely the height of the vehicle body is increased, the vehicle body and a collision object can be staggered in the height direction, and the collision object is not easy to directly collide at the position of a passenger compartment, so that the passenger compartment can be prevented from being collided by the collision object, and the purposes of effectively reducing the deformation amount and the invasion amount of the passenger compartment are achieved.

In order to enable the height of the vehicle body to be adjusted, referring to fig. 1 to 5, according to a first aspect of the present disclosure, there is provided a shock absorber assembly 1 including a cylinder 20, a shock absorbing rod 10, an inflator 30, a limit structure 40, and a stopper 50. The upper end of shock absorption rod 10 is used for being connected with the automobile body, the lower end of shock absorption rod 10 can be inserted into cylinder body 20 with moving up and down, the gas outlet of inflator 30 is communicated with the inside of cylinder body 20, inflator 30 is used for inflating gas into cylinder body 20, so that shock absorption rod 10 can move up under the action of air pressure, and the automobile body is driven to move up and down, limit structure 40 is arranged in cylinder body 20 and fixed on shock absorption rod 10, limit structure 40 is located between the lower end of shock absorption rod 10 and the upper end face of cylinder body 20, stop portion 50 is located in cylinder body 20 and fixed relative to cylinder body 20, limit structure 40 is located below stop portion 50, and limit structure 40 can stop on stop portion 50 when shock absorption rod 10 moves up.

Through the technical scheme, when a vehicle collides or is about to collide, the inflating device 30 can fill gas into the cylinder body 20, so that the air pressure in the cylinder body 20 is increased, the shock absorption rod 10 is pushed to move upwards, the vehicle body can be driven to move upwards in the process that the shock absorption rod 10 moves upwards, the vehicle body is lifted, the height of the vehicle body is increased, the vehicle body and a colliding object are staggered in the height direction, the colliding object cannot directly collide with the position of the passenger compartment easily, the purposes of preventing the passenger compartment from being collided by the colliding object and effectively reducing the deformation and the invasion of the passenger compartment are achieved, and the safety of the vehicle in collision is improved.

In addition, a limiting structure 40 is further arranged in the cylinder body 20, when the shock absorption rod 10 moves upwards to a certain height, the limiting structure 40 interferes with a stopping portion 50 fixed on the cylinder body 20, at this time, the shock absorption rod 10 cannot move upwards continuously, that is, the vehicle body is lifted to the maximum height, so that the lifting height of the vehicle body is controlled, the lifting height of the vehicle body is controlled within a proper range, and the safety of the vehicle in collision is further improved. In addition, because the limiting structure 40 is located between the lower end of the shock absorption rod 10 and the upper end surface of the cylinder body 20, the part of the shock absorption rod 10 located in the cylinder body 20 does not extend out of the cylinder body 20, so that the length requirement of the shock absorption rod 10 can be met, and the situation that the stability of the vehicle body is influenced by the fact that the vehicle body is lifted too high when the shock absorption rod 10 is lifted can be avoided.

For vehicles of different models and specifications, the height required to be lifted by the vehicle in a collision is often different, and in the present disclosure, the requirement for the lifting height required by different vehicles can be met by adjusting the position of the limiting structure 40 on the shock absorption rod 10.

In order to reduce the collision between the limiting structure 40 and the stopping portion 50, optionally, as shown in fig. 2 and 5, the limiting structure 40 may include a limiting member 41 and a buffering member 42, the limiting member 41 is fixed to the shock absorbing rod 10, the buffering member 42 is located between the limiting member 41 and the stopping portion 50, and the buffering member 42 is connected to the limiting member 41. When a vehicle collides, the inflator 30 charges gas into the cylinder 20 to push the shock absorbing rod 10 to move upwards, the shock absorbing rod 10 moves upwards and drives the limiting structure 40 to move upwards together until the limiting structure 40 stops at the stopping portion 50, and because the limiting structure 40 includes the limiting member 41 and the buffer member, when the limiting structure 40 collides with the stopping portion 50, the buffer member 42 between the limiting member 41 and the stopping portion 50 can absorb part of energy generated when the limiting member 41 collides with the stopping portion 50, so that the collision between the limiting member 41 and the stopping portion 50 is reduced, and the vibration and impact to the vehicle body in the lifting process are reduced.

Alternatively, the above-mentioned buffering member 42 may be made of rubber, polyethylene, or the like, for example, the buffering member 42 may be formed as a rubber ring, the rubber ring is formed between the limiting member 41 and the stopping member and is sleeved on the outer circumference of the damping rod 10, and when the limiting structure 40 collides with the stopping portion 50, an upper end surface of the rubber ring contacts with a lower end surface of the stopping portion 50, so as to play a role in reducing the collision between the limiting member 41 and the stopping portion 50.

Alternatively, as shown in fig. 2 and 5, the limiting member 41 may include a first portion 410 extending in the axial direction of the shock absorbing rod 10, and a second portion 411 protruding from the first portion 410 outward in the radial direction of the shock absorbing rod 10, wherein the first portion 410 is fixed to the shock absorbing rod 10, and the buffer member 42 is connected to the second portion 411. Since the first portion 410 extends along the axial direction of the shock absorbing rod 10, the first portion 410 can serve the purpose of connecting the shock absorbing rod 10, increasing the connecting area of the limiting member 41 and the shock absorbing rod 10, and thus increasing the connecting strength, and the second portion 420 protrudes from the first portion 410 outward along the radial direction of the shock absorbing rod 10 to the first portion 410, and can serve the purpose of mounting and supporting the buffer member 42.

Alternatively, first portion 410 may be a sleeve that fits over shock rod 10, and second portion 420 may be an annular flange formed on the sleeve. Alternatively, the first portion 410 and the second portion 411 may be formed in an L shape, and a plurality of stoppers 41 may be provided at intervals along the circumferential direction of the damper rod 10.

Like this, when the vehicle bumps, gaseous promotion shock attenuation pole 10 removes in cylinder body 20, and the in-process that shock attenuation pole 10 passed from lower to upper in the follow guide structure 60 promptly, guide structure 60 can play direction and spacing effect to this shock attenuation pole 10, and the shock attenuation pole 10 is difficult for taking place the condition of slope, swing at the removal in-process, and then promotes this bumper shock absorber assembly 1 and promote the stability of in-process to the automobile body.

As mentioned above, the blocking portion 50 is located in the cylinder 20 and fixed relative to the cylinder 20, and it is understood that the blocking portion 50 may be a structure provided on the cylinder 20 or a part of the cylinder 20 as long as the blocking portion 50 is fixed relative to the cylinder 20 (i.e., the blocking portion 50 does not move relative to the cylinder 20).

As an embodiment, the cylinder 20 may include a main body 21 and an end cap 22 at an upper end of the main body 21, and the stopper 50 may be an inner surface of the end cap 22.

In this way, in the process of pushing the shock absorbing rod 10 to move upwards by gas, because the guide structure 60 is disposed below the end cover 22, when the lower end surface of the guide structure 60 limits the limiting structure 40, the limiting structure 40 does not directly collide with the end cover 22 of the cylinder body 20, and thus, the situation that the end cover 22 deforms under the impact of the limiting structure 40, resulting in the shock absorbing rod 10 being entirely separated from the inside of the cylinder body 20 can be avoided.

Here, in order to improve the sealing performance of the cylinder 20 and prevent gas from flowing out from a gap between the outer wall of the damper rod 10 and the inner wall of the first through hole when a vehicle collides, which affects the pushing effect on the damper rod 10, a sealing ring may be further provided on the inner wall of the first through hole.

Alternatively, as shown in fig. 3, shock absorber assembly 1 may further include a locking mechanism 70 mounted to cylinder 20, where locking mechanism 70 is capable of releasably locking shock absorbing rod 10 to cylinder 20. That is, when the vehicle is running normally, that is, when the vehicle is not in collision, the locking mechanism 70 can lock the shock absorbing rod 10 to the cylinder 20, the shock absorbing rod 10 does not move up and down relative to the cylinder 20 at this time, that is, the vehicle body is not lifted, so that normal driving of the vehicle by a user is not affected, and when the vehicle is in collision, the locking mechanism 70 can unlock between the shock absorbing rod 10 and the cylinder 20, and at this time, the shock absorbing rod 10 can move relative to the cylinder 20 under the action of the gas generated by the inflator 30, so as to lift the height of the vehicle body.

When the vehicle is not in collision, the locking pin 71 is locked in the locking hole, and at the moment, the damping rod 10 and the cylinder 20 are kept in a relatively fixed state; when a vehicle collides, the vehicle controller controls the driving part to drive the locking pin 71 to disengage from the locking hole in response to a received collision signal, and at the same time, the inflator 30 inflates gas into the rodless cavity 24 of the cylinder 20, and pushes the shock absorbing rod 10 to move upwards under the action of the gas pressure, so that the height of the vehicle body is lifted.

Alternatively, the driving portion may include an electromagnet disposed opposite to the lock pin 71 and a spring connected between the electromagnet and the lock pin 71, and when a vehicle collision occurs, the vehicle controller may control the electromagnet to be energized and attract the lock pin 71 to move toward it, thereby disengaging the lock pin 71 from the lock hole; when the electromagnet is de-energised, the locking pin 71 can be reset under the action of the spring. Alternatively, the driving unit may be a hydraulic cylinder, a pneumatic cylinder, an electric telescopic rod, a linear motor, or the like.

In other embodiments provided by the present disclosure, the locking mechanism 70 may include an electromagnet fixedly disposed in the cylinder 20 and contacting the end plate 12, and the end plate 12 may be made of a magnetic material. Thus, when the vehicle normally runs, the electromagnet is in an energized state, the electromagnet is adsorbed on the end plate 12, at this time, the shock absorption rod 10 and the cylinder body 20 are kept in a relatively fixed state, when the vehicle collides, the vehicle controller cuts off the power of the electromagnet, the electromagnet and the end plate 12 are not mutually attracted, the inflation device 30 fills gas into the rodless cavity 24 of the cylinder body 20, and the shock absorption rod 10 is pushed to move upwards under the action of the gas pressure, so that the height of the vehicle body is lifted.

In short, the present disclosure is not limited to the specific structure and locking manner of the locking mechanism 70, as long as the locking mechanism 70 can lock the damper rod 10 to the cylinder 20 when the vehicle is not in a collision and unlock the damper rod 10 and the cylinder 20 when the vehicle is in a collision.

The inflator 30 may be any device capable of inflating the cylinder 20. For example, the inflator 30 may include an air tank and an air pump, an outlet of the air tank communicates with the inside of the cylinder 20 through the air pump, and the air pump may be turned on to pump the air in the air tank into the cylinder 20 when the vehicle collides.

Alternatively, as shown in fig. 3, the inflator 30 may include a housing 31, a gas generating agent 32 disposed in the housing 31, and an igniter 33 in contact with the gas generating agent 32, the gas outlet being formed on the housing 31, the igniter 33 being for electrical connection with a vehicle controller, the igniter 33 being capable of heating the gas generating agent 32 to cause the gas generating agent 32 to generate gas. When a vehicle collides, the vehicle controller controls the igniter 33 to ignite and heat the gas generating agent 32, the gas generating agent 32 generates gas rapidly after being heated and enters the cylinder 20, and the shock absorption rod 10 is pushed to move upwards under the action of gas pressure, so that the height of the vehicle body is lifted.

In one embodiment provided by the present disclosure, in order to reduce the overall volume of the shock absorber assembly 1, the inflator 30 may be disposed inside the cylinder 20, as shown in fig. 1, 3, and 4, such that when the inflator 30 generates gas, the gas may directly diffuse inside the cylinder 20 to lift the shock absorbing rod 10, and in an embodiment where the shock absorbing rod 10 may include a rod body 11 and an end plate 12 disposed at the lower end of the rod body 11, and the end plate 12 divides the inside of the cylinder 20 into a rod cavity 23 and a rodless cavity 24, the inflator 30 is disposed inside the rodless cavity 24, such that the gas generated by the inflator 30 can push the end plate 12 upward, and the inflator 30 is disposed without interfering with the movement of the shock absorbing rod 10.

Of course, the inflator 30 may be disposed outside the cylinder 20, an air pipe may be connected to an air outlet of the inflator 30, and the other end of the air pipe is communicated with the inside of the cylinder 20, so that when the inflator 30 generates air, the air can enter the cylinder 20 through the air pipe, and the shock absorbing rod 10 is pushed.

Alternatively, in order to avoid the influence or damage to the cylinder 20 or the damper rod 10 caused by impurities contained in the gas generated by the gas generating agent 32, in the present disclosure, as shown in fig. 3, the inflator 30 further includes a gas filter 35, a partition plate 34 is disposed in the housing 31, the partition plate 34 divides the interior of the housing 31 into a first chamber 37 and a second chamber 36, the gas generating agent 32 is disposed in the first chamber 37, the gas filter 35 is disposed in the second chamber 36, a second through hole communicating the first chamber 37 with the second chamber 36 is formed in the partition plate 34, and the gas outlet is communicated with the second chamber 36. Thus, when the vehicle collides, so that the igniter 33 heats the inflator 30 upon receiving the activation signal, a large amount of gas is generated, and the gas generated in the first chamber 37 flows into the second chamber 36 through the second through hole and flows into the interior of the cylinder 20 from the gas outlet to push the shock rod 10 to move upward, thereby moving the vehicle body. In the process of flowing gas from the first chamber 37 to the second chamber 36, the gas filter element 35 can filter and isolate other products, except gas, generated after the reaction of the gas generating agent 32, so as to prevent the products from entering the cylinder 20 and causing interference or interference on the up-and-down movement of the shock absorber.

Alternatively, the gas generating agent 32 may be sodium azide, which decomposes to generate nitrogen gas when heated, and the reaction is rapid, so that the vehicle body can be lifted rapidly, and the nitrogen gas generated by the reaction does not pollute the environment. Alternatively, the gas generant 32 may be ammonium nitrate.

In addition, the vehicle controller mentioned above may be an electronic control unit of the vehicle, i.e., a driving computer, which is electrically connected to a safety sensor capable of detecting collision information of the vehicle, and after receiving the collision information, the vehicle controller may control the igniter 33 to heat the gas generating agent 32, thereby generating a large amount of gas, and control the locking mechanism 70 to unlock the damper rod 10 and the cylinder 20, so that the damper rod 10 may move upward, thereby lifting the vehicle body.

According to a second aspect of the present disclosure, a vehicle is provided, comprising a shock absorber assembly 1 as above. The vehicle has all the technical effects of the shock absorber assembly 1, and the detailed description is omitted.
