[0002] With the rapid development of the automobile industry, vehicle safety has become the focus of people's attention. In traffic accidents, the anti-collision ability of vehicles is directly related to the life safety of passengers and the degree of damage to the vehicle. However, the existing vehicle anti-collision technology still has some shortcomings.

[0003] Traditional anti-collision structures of vehicles have limited effects in absorbing and dispersing collision energy, and often fail to function quickly and effectively in the event of a collision, causing the impact force to cause greater damage to the vehicle and passengers. In addition, some anti-collision devices have a low level of intelligence and cannot accurately detect collisions in real time and make corresponding adjustments, making it difficult to adapt to complex traffic environments and diverse collision scenarios.

[0004] At the same time, the existing energy absorption structure design is not reasonable enough to achieve phased and multi-level energy absorption, making the energy absorption effect less than ideal. Moreover, the stability of some vehicle anti-collision structures in non-collision states needs to be improved, which is prone to potential safety hazards. In addition, the wear resistance and service life of vehicle anti-collision beams also need to be further improved.

If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the invention.

[0024] See also Figure 1-4 The vehicle anti-collision lifting device comprises an anti-collision beam 1, and energy absorbing components 2 for positioning the anti-collision beam 1 at the front end or rear end of the vehicle body are installed at both the left and right ends.

[0025] The energy absorption assembly 2 specifically includes an energy absorption box 21, a solenoid valve 22, an energy absorption structure 23, a locking partition 24, a slider 25, a connecting column 26, a connecting plate 27 and a welded end plate 28. The welded end plate 28 is installed at one end of the position where the cross beam 1 is to be installed inside the vehicle, and the energy absorption box 21 is installed at the front end of the welded end plate 28. The piston rod 26 is slidably connected to the front end of the energy absorption box 21, the connecting plate 27 is connected to the front end of the piston rod 26 and welded to the back side of the end of the anti-collision cross beam 1, and the inner end of the piston rod 26 extends into the interior of the energy absorption box 21 and is connected to the slider 25. The energy absorption structure 23 is installed inside the energy absorption box 21, and the output end of the solenoid valve 22 is connected to the tail end of the energy absorption structure 23. When a collision occurs, the solenoid valve 22 can quickly push the energy absorption structure 23 forward to the working position.

[0026] The energy absorbing structure 23 specifically includes three primary energy absorbing sleeves 231, secondary energy absorbing sleeves 232 and tertiary energy absorbing sleeves 233 which are connected layer by layer from front to back. The primary energy absorbing sleeves 231, secondary energy absorbing sleeves 232 and tertiary energy absorbing sleeves 233 are filled with primary energy absorbing filling blocks 234, secondary energy absorbing filling blocks 235 and tertiary energy absorbing filling blocks 236 respectively. A plug-in column 237 is slidably inserted inside the front end of the tertiary energy absorbing sleeve 233, and a front contact plate 238 is installed at the front end of the plug-in column 237. The front ends of the primary energy absorbing filling blocks 234, secondary energy absorbing filling blocks 235 and tertiary energy absorbing filling blocks 236 are respectively pressed against the rear end surfaces of the secondary energy absorbing sleeves 232, tertiary energy absorbing sleeves 233 and the plug-in column 237. The first-level energy-absorbing filler block 234 is made of foam metal, which has good energy absorption and buffering performance and can quickly absorb part of the energy at the initial stage of impact; the second-level energy-absorbing filler block 235 is made of high-elastic rubber, which can further enhance the buffering effect and reduce the transmission of impact force; the third-level energy-absorbing filler block 236 is made of polyurethane foam, which can effectively disperse and absorb the remaining impact energy. This layered energy-absorbing structure can gradually play a role according to the intensity and stage of the impact, achieving a more comprehensive and efficient energy-absorbing effect.

[0027] The energy absorbing box 21 is also provided with a locking partition 24 on the back side of the slider 25 to limit the slider 25 from sliding backward when there is no impact, thus ensuring the stability of the energy absorbing structure in a normal state. When an impact occurs, the solenoid valve is activated to break the locking state, so that the energy absorbing structure can respond quickly.

[0028] In addition, the device also includes a sensor system and a control system. The sensor system is used to detect objects and collisions around the vehicle. The system includes multiple sensors, which are respectively arranged at the front, rear, side and top of the vehicle to form an all-round monitoring network, which can accurately transmit the detected information, such as the distance, speed, direction, etc. of the object to the control system in real time. The control system is like the brain of the device. It is closely connected with the sensor system and the energy absorption component 2, and can quickly and accurately analyze key parameters such as the position, speed and force of the collision according to the collision detected by the sensor system. Then, the control system intelligently controls the working state of the energy absorption component 2 according to these parameters, such as accurately adjusting the opening time and strength of the solenoid valve, so that the energy absorption structure 23 of the energy absorption component 2 can be quickly pushed to the work station at the best time to achieve the best anti-collision effect.

[0029] The surface of the anti-collision beam 1 is provided with a wear-resistant coating, which can not only improve its service life, but also resist various frictions and wears during the driving process of the vehicle, and always maintain a good appearance and performance. At the same time, the anti-collision beam plays a key role in buffering and supporting during the collision. It can withstand and disperse the impact force, further reduce the damage to the vehicle and passengers caused by the collision, and provide more reliable safety protection for the people in the vehicle.

[0030] In actual use, the vehicle's anti-collision improvement method is as follows: The sensor system detects objects and collisions around the vehicle in real time and transmits the detected information to the control system.

[0031] The control system carefully determines parameters such as the location, speed and force of the impact based on the impact detected by the sensor system.

[0032] The control system accurately controls the working state of the energy absorbing assembly 2 according to the impact parameters, so that the energy absorbing structure 23 of the energy absorbing assembly 2 is quickly pushed to the work station.

[0033] The anti-collision beam 1 fully exerts its buffering and supporting functions during the collision, effectively further reducing the damage to the vehicle and passengers caused by the collision.
