DETAILED DESCRIPTION

[0042] The following will be combined with the 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, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0043] Embodiment 1:

[0044] This embodiment provides a shock absorber assembly with multiple swing angles, including:

[0045] The shock absorber body 1 has connection structures for installation at both ends;

[0046] The connection structure includes:

[0047] A connecting part 2 connected to both ends of the shock absorber body 1;

[0048] The spherical portion 3 is connected to an end of the connecting portion 2 away from the shock absorber body 1 and is penetrated by a through hole 4;

[0049] The sleeve 5 is installed in the through hole 4 and a gap is formed between the sleeve 5 and the inner wall of the through hole 4;

[0050] The elastic pad 6 is installed in the gap between the surface of the sleeve 5 and the inner wall of the through hole 4;

[0051] Meanwhile, the specific structure of the shock absorber body 1 is an existing mature technology and will not be described here in detail. The connecting part 2 and the spherical part 3 adopt an integrated structure, and the connecting part 2 and the shock absorber body 1 can be welded, and the elastic pad 6 is made of rubber.

[0052] It can be seen from the present embodiment that by setting the connection structure at both ends of the shock absorber body 1 into a connecting part 2 and a spherical part 3, and opening a through hole 4 in the spherical part 3, a gap is formed between the inside of the through hole 4 and the sleeve 5, and then the gap is filled with an elastic pad 6. After the shock absorber assembly is installed, the shock absorber body 1 can have a certain swing angle in the lateral direction, which can avoid damage to the shock absorber when dealing with complex road conditions and extend its service life.

[0053] Embodiment 2:

[0054] This embodiment provides a shock absorber assembly with multiple swing angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0055] The through hole 4 includes a middle section 40 and tapered sections 41 located on both axial sides of the middle section 40;

[0056] There are two elastic pads 6, which are respectively installed in the conical section 41 and adapted to the conical section 41;

[0057] At the same time, in order to further improve the structural strength, an adhesive layer may be provided between the elastic pad 6 and the conical section 41 to form a tight connection between the elastic pad 6 and the spherical portion 3;

[0058] In addition, the axial length of the middle section 40 is preferably set according to the diameter of the inner wall of the sleeve 5 so as not to affect the radial swing of the sleeve 5. Specifically, the larger the diameter, the longer the axial length of the middle section 40 can be set, which can improve the stability of the sleeve 5 in the through hole 4.

[0059] It can be seen from this embodiment that by setting the two ends of the through hole 4 into conical sections 41 and setting the elastic pad 6 into a conical structure adapted thereto, the lateral swing angle of the shock absorber body 1 can be appropriately increased, and when dealing with complex road surfaces, damage to the shock absorber can be further avoided and the service life can be extended.

[0061] This embodiment provides a shock absorber assembly with multiple swing angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0062] The sleeve 5 includes a first barrel 50 and a second barrel 51 , and a buckle structure is provided between the first barrel 50 and the second barrel 51 .

[0063] It can be seen from this embodiment that the convenience of installing the sleeve 5 can be improved by using the first cylinder 50 and the second cylinder 51 of the sleeve 5 to be connected by snap-fit ​​connection.

[0064] Embodiment 4:

[0065] This embodiment provides a shock absorber assembly with multiple swing angles. In addition to the technical solutions of the above embodiments, it also has the following technical features. The buckle structure includes:

[0066] The hook portion 52 is installed on a side of the first cylinder 50 close to the second cylinder 51 and includes a plurality of hooks 520 arranged at equal intervals around the circumference;

[0067] The second cylinder 51 is provided with a slot 510 adapted to the hook 520;

[0068] Meanwhile, the hook portion 52 and the first cylinder 50 may be in an integrated structure.

[0069] It can be seen from this embodiment that the connection stability between the first cylinder 50 and the second cylinder 51 is improved by using the cooperation between the hook 520 and the groove 510, and multiple hooks 520 are arranged at equal intervals around the circumference to facilitate the connection strength between the first cylinder 50 and the second cylinder 51.

[0070] Embodiment 5:

[0071] This embodiment provides a shock absorber assembly with multiple swing angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0072] A first annular groove 521 is formed on a side of the hook portion 52 close to the axis, and a second annular groove 511 is formed on a side of the second cylinder 51 away from the axis.

[0073] The first cylinder 50 and the second cylinder 51 are coaxially arranged, and the inner walls thereof are smoothly transitioned.

[0074] It can be seen from the present embodiment that by opening a first annular groove 521 in the hook portion 52 and a second annular groove 511 in the second cylinder 51, the first cylinder 50 and the second cylinder 51 are tightly connected through the snap-fit ​​structure, thereby avoiding a gap between the first cylinder 50 and the second cylinder 51 and the elastic pad 6, and improving the assembly stability.

[0075] Embodiment 6:

[0076] This embodiment provides a shock absorber assembly with multiple swing angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0078] A second chamfer 512 is formed at one end of the second tube 51 close to the hook portion 52 .

[0079] It can be seen from this embodiment that the provision of the first chamfer 522 and the second chamfer 512 further improves the convenience of installing and cooperating the first cylinder 50 and the second cylinder 51, making it easier for the hook portion 52 to slide into the second annular groove 511 and the second cylinder 51 to slide into the first annular groove 521.

[0084] Meanwhile, the elastic ring 53 is made of rubber and has a tendency to shrink toward the axis when being sleeved on the surface of the hook portion 52 .

[0085] It can be seen from this embodiment that by providing the elastic ring 53, when the first cylinder 50 is installed, the multiple hooks 520 are bent toward the axis, and when the second cylinder 51 slides into the first annular groove 521, the multiple hooks 520 can be radially spread outward, thereby effectively improving the connection stability between the hooks 520 and the groove 510, making it difficult to fall off;

[0086] The third annular groove 54 can improve the installation stability of the elastic ring 53 on the surface of the hook portion 52 and prevent the elastic ring 53 from moving in the axial direction.

[0087] Embodiment 8:

[0088] This embodiment provides a shock absorber assembly with multiple swing angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features:
