[0034] The following combination Figure 1 , describing an anti-collision frame 100 according to an embodiment of the present invention.

[0035] like Figure 1 As shown, the anti-collision frame 100 according to an embodiment of the present invention includes a longitudinal beam 10 and an anti-collision beam 20 .

[0036] The longitudinal beam 10 has a main chamber 101 and a plurality of sub-chambers 102. Each sub-chamber 102 has a liquid passage hole 1021. Any two adjacent sub-chambers 102 are connected through the liquid passage hole 1021. The sub-chamber 102 adjacent to the main chamber 101 is connected to the main chamber 101 through the liquid passage hole 1021. The longitudinal beam 10 has a side wall cavity 103, which is connected to the sub-chamber 102. The anti-collision beam 20 is movably disposed in the main chamber 101 along the length of the longitudinal beam 10. The anti-collision beam 20 has a liquid storage cavity 201. The liquid storage cavity 201 has a liquid outlet hole 2011. The liquid storage cavity 201 is connected to the main chamber 101 through the liquid outlet hole 2011. The side wall cavity 103 is connected to the liquid storage cavity 201. A buffer is provided in the cavity defined by the anti-collision beam 20 and the main chamber 101.

[0037] It can be understood that the main chamber 101 is located at the front end of the longitudinal beam 10, and the anti-collision beam 20 is located within the main chamber 101 and receives force at the front end. When the anti-collision beam 20 is hit by a collision, the impact force can drive the anti-collision beam 20 to move within the main chamber 101 toward the rear of the longitudinal beam 10, while compressing the buffer within the cavity. With the help of the buffer's motion damping and anti-compression properties, the anti-collision beam 20 is prevented from continuing to move and absorbs the impact energy. If the impact force is large, the backward movement of the anti-collision beam 20 compresses the buffer, which increases the pressure of the buffer. A portion of the buffer can pass through the liquid hole 1021 and flow from the main chamber 101 into the sub-chamber 102. Because the liquid hole 1021 has a throttling effect, the damping of the buffer is increased, and the movement resistance is also increased. As the buffer flows through multiple sub-chambers 102 in sequence, the impact energy is gradually attenuated and absorbed.

[0038] When the impact force is particularly large, the buffer solution in the sub-chamber 102 can flow into the side wall cavity 103. As the anti-collision beam 20 continues to move backward, the buffer solution flows along the side wall cavity 103 to the liquid storage cavity 201 of the anti-collision beam 20, and then flows back to the main chamber 101 through the liquid outlet 2011 of the liquid storage cavity 201, forming a complete liquid circuit cycle. In this process, the buffer solution, the liquid outlet 1021, and the side wall cavity 103 absorb and attenuate the impact energy multiple times, so that the impact energy can be attenuated to a minimum, and the collision deformation of the anti-collision beam 20 is also minimized.

[0039] According to the anti-collision frame 100 of the embodiment of the present invention, by filling the cavity defined between the anti-collision beam 20 and the main chamber 101 with a buffer solution, the impact energy of the anti-collision beam 20 when it is hit can be absorbed and attenuated by the buffer solution. At the same time, the impact energy can be absorbed and attenuated multiple times by means of the liquid hole 1021 and the multiple sub-chambers 102, thereby significantly enhancing the anti-collision effect. By configuring the longitudinal beam 10 to have a side wall cavity 103 and the anti-collision beam 20 to have a liquid storage cavity 201, the liquid storage cavity 201 is connected to the main chamber 101 through the liquid outlet 2011, so that the main chamber 101, the sub-chamber 102, the side wall cavity 103, and the liquid storage cavity 201 can form a complete circulation loop, further absorbing and attenuating the impact energy, improving the anti-collision performance, and helping to reduce the degree of deformation of the anti-collision beam 20.

[0040] In some embodiments, such as Figure 1 As shown, the main chamber 101 extends along the length of the longitudinal beam 10, and the multiple sub-chambers 102 are located on the side of the main chamber 101 away from the anti-collision beam 20. In other words, the buffer can be transferred along the direction of the frontal impact of the anti-collision beam 20, flowing from the main chamber 101 through the liquid holes 1021 into the sub-chambers 102, making the transmission path of the impact energy more optimized and maximizing the absorption and attenuation of the impact energy by the buffer.

[0041] In another embodiment, the main chamber 101 extends along the length of the stringer 10, and the plurality of sub-chambers 102 can be provided on both sides of the main chamber 101 along the length of the stringer 10. For example, the plurality of sub-chambers 102 can be provided on the upper and lower sides of the main chamber 101, and the buffer solution can flow upward and downward into the sub-chambers 102, which can also serve as an energy absorption function.

[0042] In some embodiments, such as Figure 1 As shown, multiple sub-chambers 102 are arranged in sequence along the length direction of the longitudinal beam 10, and the length direction of the longitudinal beam 10 can be the front-to-back direction of the vehicle frame. That is to say, multiple sub-chambers 102 are arranged in sequence along the frontal impact direction of the anti-collision beam 20. When the anti-collision beam 20 continues to move backward to compress the buffer, as the pressure increases, the buffer flows into the multiple sub-chambers 102 arranged in sequence one by one. Since the arrangement direction of the multiple sub-chambers 102 is the same as the direction of the frontal impact, the impact energy can be absorbed with maximum efficiency.

[0043] In some embodiments, such as Figure 1 As shown, at least one of the four circumferential sidewalls of the longitudinal beam 10 has a sidewall cavity 103. For example, the upper and lower sidewalls of the longitudinal beam 10 may be provided with sidewall cavities 103, or the upper, lower, left, and right sidewalls of the longitudinal beam 10 may all be provided with sidewall cavities 103. Increasing the number of sidewall cavities 103 can increase the flow rate of the liquid circulation, enhancing absorption and attenuation.

[0044] In some embodiments, such as Figure 1 As shown, an elastic baffle 104 is provided between the main chamber 101 and the sub-chamber 102, and between any two adjacent sub-chambers 102. A liquid passage hole 1021 is provided on the elastic baffle 104. When the anti-collision beam 20 is impacted and moves within the main chamber 101, the buffer can push the elastic baffle 104 to deform, thereby increasing the diameter of the liquid passage hole 1021. The elastic baffle 104 is used to separate the main chamber 101 and the sub-chamber 102. If the impact force is particularly large, the liquid flow through the liquid passage hole 1021 cannot fully absorb and attenuate the impact energy. As the anti-collision beam 20 continues to move backward, compressing the buffer, the pressure of the buffer increases, and the elastic baffle 104 can undergo plastic deformation, increasing the diameter of the liquid passage hole 1021, accelerating the flow of the buffer into the rear sub-chamber 102, and improving the ability to absorb and attenuate impact energy.

[0045] In some embodiments, such as Figure 1 As shown, the anti-collision frame 100 further includes a sealing ring 30, which is sleeved on the anti-collision beam 20. The sealing ring 30 is sleeved on the main chamber 101. The main chamber 101, the anti-collision beam 20 and the sealing ring 30 jointly define a transition chamber 105. The side wall chamber 103 has a liquid return hole 1031 connected to the transition chamber 105, and the liquid storage chamber 201 has a liquid inlet hole 2012 connected to the transition chamber 105. It can be understood that the transition chamber 105 is jointly defined by the main chamber 101, the anti-collision beam 20 and the sealing ring 30. When the anti-collision beam 20 moves backward, the buffer solution in the side wall chamber 103 can enter the transition chamber 105 through the liquid return hole 1031, and then enter the liquid storage chamber 201 from the transition chamber 105 through the liquid inlet hole 2012, ensuring that the buffer solution can enter the liquid storage chamber 201 to achieve liquid circulation during the backward movement of the anti-collision beam 20.

[0046] Alternatively, as Figure 1 As shown, multiple return holes 1031 are provided along the length of the longitudinal beam 10. By increasing the number of return holes 1031, the buffer's reflux capacity is increased, allowing the buffer to quickly flow back into the transition cavity 105, thereby improving energy absorption. For example, two return holes 1031 are provided at intervals along the longitudinal beam 10 in the front-to-back direction. When the buffer flows back into the sidewall cavity 103, it can enter the transition cavity 105 through the two return holes 1031, respectively. This reduces the buffer's flow pressure, increases its flow rate, and facilitates absorption of collision energy.

[0047] In some embodiments, such as Figure 1As shown, the liquid storage chamber 201 includes a plurality of sub-chambers 2013, which are arranged in sequence along the length of the longitudinal beam 10. Each sub-chamber 2013 has a liquid flow hole 20131. Any two adjacent sub-chambers 2013 are connected through the liquid flow hole 20131. Each sub-chamber 2013 has a liquid inlet hole 2012. The longitudinal direction of the anti-collision beam 20 can be the front-to-back direction. When the anti-collision beam 20 continues to move backward, the pressure of the buffer solution increases. At this time, part of the buffer solution flows into the sub-chamber 2013 along the side wall cavity 103. Since each sub-chamber 2013 has a liquid inlet hole 2012, the liquid inlet hole 2012 also has a throttling effect, increasing the movement resistance and the damping of the buffer solution, thereby absorbing and attenuating the impact energy.

[0048] In some embodiments, such as Figure 1 As shown, the side wall cavity 103 has a plurality of liquid return holes 1032, and the plurality of liquid return holes 1032 are arranged in a one-to-one correspondence with the plurality of sub-chambers 102, or the plurality of liquid return holes 1032 are arranged in a one-to-one correspondence with some of the sub-chambers 102, so that the side wall cavity 103 is connected to the plurality of sub-chambers 102. For example, the number of the plurality of liquid return holes 1032 is equal to the number of the plurality of sub-chambers 102, and they are arranged in a one-to-one correspondence with each other, so that each sub-chamber 102 is connected to the side wall cavity 103. For example, the number of the plurality of liquid return holes 1032 is equal to the number of some of the sub-chambers 102 in the plurality of sub-chambers 102, so that each sub-chamber 102 in the part of the sub-chambers 102 is connected to the side wall cavity 103. The plurality of liquid return holes 1032 enable the buffer solution in the sub-chamber 102 to flow back into the side wall cavity 103.

[0049] like Figure 1 As shown, for example, the longitudinal beam 10 may have three sub-cavities 102, and the sidewall cavity 103 may have three liquid return holes 1032, with the three liquid return holes 1032 being arranged in a one-to-one correspondence with the three sub-cavities 102. For another example, the sidewall cavity 103 may have two liquid return holes 1032, with the two liquid return holes 1032 being arranged in a one-to-one correspondence with the two rear sub-cavities 102 among the three sub-cavities 102.

[0050] In some embodiments, the buffer is a viscous liquid. For example, the viscous liquid can be viscous mechanical oil, which has a large damping capacity and can provide a good energy absorption effect.

[0051] Optionally, the anti-collision beam 20 can be a hollow beam structure, thereby forming a liquid storage cavity 201 inside. This structure makes it easy to form the liquid storage cavity 201, and there is no need to re-open the liquid storage cavity 201 on the beam body, which can reduce costs.

[0052] A specific embodiment of the anti-collision frame 100 of the present invention will be described below with reference to the accompanying drawings.

[0053] like Figure 1As shown, an anti-collision frame 100 includes: a longitudinal beam 10, an anti-collision beam 20, and a sealing ring 30.

[0054] The front end of the longitudinal beam 10 has a main chamber 101 and three sub-chambers 102. Each sub-chamber 102 has a liquid hole 1021. Any two adjacent sub-chambers 102 are connected through the liquid hole 1021. The sub-chamber 102 close to the main chamber 101 is connected to the main chamber 101 through the liquid hole 1021. The longitudinal beam 10 has a side wall cavity 103, which is connected to the sub-chamber 102.

[0055] The anti-collision beam 20 is movably disposed within the main chamber 101 along the longitudinal direction of the longitudinal beam 10. The anti-collision beam 20 has a liquid storage chamber 201 with a liquid outlet 2011. The liquid storage chamber 201 communicates with the main chamber 101 through the liquid outlet 2011. The sidewall chamber 103 also communicates with the liquid storage chamber 201. A buffer solution is disposed within the cavity defined by the anti-collision beam 20 and the main chamber 101. The viscous liquid is viscous machine oil.

[0056] The main chamber 101 extends in the front-rear direction of the longitudinal beam 10 , and the three sub-chambers 102 are provided at the rear end of the main chamber 101 .

[0057] The three sub-cavities 102 are sequentially arranged along the front-rear direction of the longitudinal beam 10 .

[0058] The upper and lower side walls of the longitudinal beam 10 have a side wall cavity 103. The side wall cavity 103 has two liquid return holes 1032, which are arranged in a one-to-one correspondence with the two sub-cavities 102 located at the rear side, so that the side wall cavity 103 is connected to the two sub-cavities 102.

[0059] An elastic partition 104 is provided between the main chamber 101 and the sub-chamber 102, and between any two adjacent sub-chambers 102. The liquid hole 1021 is provided on the elastic partition 104. When the anti-collision beam 20 is hit and moves in the main chamber 101, the buffer can push the elastic partition 104 to deform, so that the aperture of the liquid hole 1021 increases.

[0060] The liquid storage chamber 201 includes four sub-chambers 2013, which are arranged in sequence along the front-to-back direction of the longitudinal beam 10. Each sub-chamber 2013 has a liquid flow hole 20131. Any two adjacent sub-chambers 2013 are connected through the liquid flow hole 20131. Each sub-chamber 2013 has a liquid inlet hole 2012.

[0061] The sealing ring 30 is sleeved on the anti-collision beam 20, and the sealing ring 30 is sleeved on the main chamber 101. The main chamber 101, the anti-collision beam 20 and the sealing ring 30 jointly define a transition chamber 105. The side wall chamber 103 has a return liquid hole 1031 connected to the transition chamber 105, and the liquid storage chamber 201 has a liquid inlet hole 2012 connected to the transition chamber 105.

[0062] Two liquid return holes 1031 are provided at intervals along the front-rear direction of the longitudinal beam 10 .

[0063] In summary, the anti-collision frame 100 of the present invention can be applied to pickup trucks to replace the traditional frame longitudinal beam structure of pickup trucks, eliminate the sound-absorbing box anti-collision structure between the traditional frame longitudinal beam and the anti-collision beam, and optimize the frame anti-collision structure. By adding a viscous liquid into the cavity of the front section of the longitudinal beam 10, and dividing the cavity into a main chamber 101 and three sub-chambers 102, the chambers are connected through the elastic partition 104 and the liquid holes 1021 on the elastic partition 104. These structures constitute a collision energy absorption structure. It has good energy absorption and energy transmission path. Its main function is to exert the front energy absorption capacity, absorb and transmit the collision energy through the energy absorption device, and improve the collision performance of the vehicle.

[0064] A vehicle according to an embodiment of the present invention includes the anti-collision frame 100 described above.

[0065] The longitudinal beam 10 is a longitudinal beam of the vehicle frame, and the anti-collision beam 20 is a front anti-collision beam of the vehicle. When the front end of the vehicle is hit, the anti-collision frame 100 can play a good anti-collision role.

[0066] According to the vehicle of the embodiment of the present invention, the anti-collision frame 100 can absorb and attenuate the impact energy received by the anti-collision beam 20, and can absorb and attenuate the energy multiple times, thereby significantly enhancing the anti-collision effect.
