DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0035] Example 1:

[0036] This embodiment provides a high-load-bearing shock absorber, comprising:

[0037] Piston assembly 1;

[0038] Shock absorber assembly 2;

[0039] Transformer component 3;

[0040] The shock absorbing assembly 2 and the voltage transformation assembly 3 are both arranged on the piston assembly 1 .

[0041] As can be seen from this embodiment, a high-load-bearing shock absorber includes a piston assembly 1, a shock absorbing assembly 2 and a voltage-changing assembly 3;

[0042] The shock absorbing assembly 2 and the transformer assembly 3 are installed on the piston assembly 1. The shock absorbing assembly 2 provides damping when the piston assembly 1 moves to achieve shock absorption. Furthermore, the transformer assembly 3 is used to adjust the pressure changes in the piston mating part of the piston assembly 1, thereby changing the path of the piston movement, thereby adjusting the shock absorption effect, and thus helping to improve the load-bearing capacity.

[0043] Example 2:

[0044] This embodiment provides a high-load-bearing shock absorber, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] The piston assembly 1 comprises:

[0046] The sleeve 11 has a matching hole 111 formed therein, and one end of the matching hole 111 is configured as a closing end 112 and the other end is configured as a mounting end;

[0047] The rod body 12 includes a mating end 121 and a first connecting end 122 . The mating end 121 is disposed in the mating hole 111 , and the first connecting end 122 extends from the closing end 112 to the outside of the sleeve 11 .

[0048] The connecting plug 13 has a first connecting end 122 disposed on the mounting end, a sealed chamber is formed between the connecting plug 13 and the mating end 121, and a second connecting end is disposed on the outside of the connecting plug 13;

[0049] The sleeve 11 is provided with an interface end 113 , which corresponds to the sealed chamber, and the transformer assembly 3 is connected to the interface end 113 .

[0050] As can be seen from this embodiment, the piston assembly 1 includes a sleeve 11, a rod body 12 and a connecting plug 13;

[0051] A matching hole 111 is formed in the sleeve 11, and one end of the matching hole is set as a closing end 112. The rod body 12 includes a matching end 121 and a first connecting end 122. The matching end 121 is connected to the matching hole 111 and is limited by the closing end 112. Piston movement is generated between the matching end 121 and the sleeve 11. The first connecting end 122 extends outside the sleeve 11 and is used to connect to the frame. The connecting plug 13 is set at the other end of the matching hole 111, and the other end of the connecting plug 13 is provided with a second connecting end and is used to connect to the frame.

[0052] A closed chamber is formed between the connecting plug 13 and the mating end 121, and the transformer assembly 3 is used to increase or reduce the pressure of the sealed chamber through the interface end 113. When increasing the pressure, the pressure in the closed chamber is high, which provides an upward force to the mating end 121, thereby increasing the damping between the mating end 121 and the mating hole 111, making it difficult for the mating end 121 to perform piston movement with the mating hole 111. When reducing the pressure, the damping between the mating end 121 and the mating hole 111 is small, and it is easy to perform piston movement with the mating hole 111, thereby achieving the function of adjusting the load-bearing capacity.

[0053] Example 3:

[0054] This embodiment provides a high-load-bearing shock absorber, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] The shock absorbing assembly 2 includes:

[0056] A first spring 21, the first spring 21 is arranged between the first connecting end 122 and the sleeve 11;

[0057] A second spring 22 , which is disposed between the connecting plug 13 and the mating end 121 ;

[0058] The limiting block 23 is movably disposed on the first connecting end 122 and abuts against the first spring 21 .

[0059] It can be seen from this embodiment that the first spring 21 is sleeved on the first connecting end 122 and abuts between the sleeve 11 and the limit block 23. The second spring 22 is installed in the closed chamber, and both ends abut between the connecting plug 13 and the mating end 121. By arranging the first spring 21 and the second spring 22 to fit on the piston assembly 1, the elastic damping effect is improved, thereby enhancing the shock absorption effect.

[0060] Example 4:

[0061] This embodiment provides a high-load-bearing shock absorber, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] The transformer assembly 3 includes:

[0063] A gas cylinder 31, wherein the end of the gas cylinder 31 is provided with an air inlet end and an air outlet end;

[0064] An air pump 32 is provided on the air outlet end and connected to the interface end 113 via a hose 33;

[0065] The airbag 34 is disposed in the sealed chamber and connected to the interface end 113;

[0066] A buffer pad is provided between the airbag 34 and the mating end 121 .

[0067] As can be seen from this embodiment, the gas cylinder 31 is mounted on the vehicle frame, and one end of the gas cylinder 31 is set as the air inlet end, and the other end is set as the air outlet end and is connected to the air pump 32. The air pump 32 is connected to the interface end 113 through a hose 33. The air bag 34 is installed in the sealed chamber, and a buffer is provided between the air bag 34 and the mating end 121. The buffer protects the air bag 34. During installation, the air bag 34 is installed inside the second spring 22 and its two ends abut against the mating end 121 and the connecting plug 13.

[0068] The air pump 32 changes the force of the air bag 34 against the mating end 121 by injecting or releasing gas into the air bag 34, thereby achieving load-bearing adjustment.

[0069] Example 5:

[0070] This embodiment provides a high-load-bearing shock absorber, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] The filter screen 4 is arranged on the air inlet end and the air outlet end, and activated carbon 5 is arranged on the inner side of the filter screen 4.

[0072] It can be seen from this embodiment that by setting filter screens 4 on the air inlet and outlet ends and setting activated carbon 5 between the filter screens 4 on both sides to filter impurities in the gas, impurities can be prevented from invading the closed chamber and causing erosion to the piston assembly 1.

[0073] Example 6:
