[0027] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Where several specific embodiments exist, features in these embodiments can be combined with each other without conflict. When the description relates to the drawings, unless otherwise stated, the same numbers or symbols in different drawings represent the same or similar elements. The content described in the following exemplary embodiments does not represent all embodiments of this utility model; rather, they are merely examples of products consistent with this utility model and as described in the claims.

[0028] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the scope of protection of this invention. It should be understood that terms such as "first," "second," and similar words used in the specification and claims of this invention do not indicate any order, quantity, or importance, but are merely used to distinguish the features.

[0029] Please refer to Figures 1 to 11 As shown, this utility model discloses a shock absorber housing assembly 100, which includes a first housing 1 and a second housing 2 that is separately disposed from the first housing 1 and welded together.

[0030] In the embodiment illustrated in this utility model, the first housing 1 includes a liquid storage cylinder 11, a first valve housing 12 connected to and protruding from the liquid storage cylinder 11, a second valve housing 13 connected to and protruding from the liquid storage cylinder 11, a bottom cover 14 welded and fixed to the bottom of the liquid storage cylinder 11, and a spring tray 15 sleeved and fixed to the liquid storage cylinder 11. In the embodiment illustrated in this utility model, the first valve housing 12 and the second valve housing 13 are respectively used to install solenoid valves. The first valve housing 12 and the second valve housing 13 are both separately disposed from the liquid storage cylinder 11, but are welded and fixed together with the liquid storage cylinder 11.

[0031] In the embodiment illustrated in this utility model, the liquid storage cylinder 11 is provided with a liquid storage cavity 111, the first valve housing 12 is provided with a first receiving cavity 121 communicating with the liquid storage cavity 111, and the second valve housing 13 is provided with a second receiving cavity 131 communicating with the liquid storage cavity 111. In the embodiment illustrated in this utility model, the liquid storage cylinder 11, the first valve housing 12, and the second valve housing 13 are all generally cylindrical, wherein the central axis of the first valve housing 12 is perpendicular to the central axis of the liquid storage cylinder 11, and the central axis of the second valve housing 13 is perpendicular to the central axis of the liquid storage cylinder 11. The first valve housing 12 and the second valve housing 13 are generally located on both sides of the liquid storage cylinder 11.

[0032] The bottom cover 14 is located at the bottom of the liquid storage cylinder 11 and is welded and fixed to the inner wall of the liquid storage cylinder 11 to seal the bottom of the liquid storage cavity 111. Specifically, in the embodiment illustrated in this utility model, the bottom cover 14 has a base 141 and a raised portion 142 protruding downward from the base 141. The raised portion 142 protrudes to the side away from the liquid storage cavity 111. The top surface of the raised portion 142 has a conical bottom cavity 1421 that communicates with the liquid storage cavity 111.

[0033] In the embodiment illustrated in this utility model, the weld between the base 141 and the inner wall of the liquid storage cylinder 11 is located outside the liquid storage cavity 111 to avoid the welding slag from the welding causing adverse effects on the vibration damper. In one embodiment of this utility model, the weld between the base 141 and the inner wall of the liquid storage cylinder 11 is a first annular weld 143 to improve the welding quality and ensure a seal at the bottom of the liquid storage cavity 111.

[0034] In the embodiment illustrated in this utility model, the liquid storage cylinder 11 has a first bottom surface 112, and the raised portion 142 has a second bottom surface 1422, wherein the second bottom surface 1422 is located above the first bottom surface 112, that is, the bottom cover 14 is recessed above the first bottom surface 112 and does not protrude downward from the first bottom surface 112. In other words, in the embodiment illustrated in this utility model, the first housing 1 has a gap 113 located between the first bottom surface 112 and the second bottom surface 1422.

[0035] The second housing 2 is a ram's horn, which includes a mounting portion 21, a first support portion 22 extending from one side of the mounting portion 21, and a second support portion 23 extending from the other side of the mounting portion 21.

[0036] The mounting portion 21 is provided with a mounting cavity 211 and a mounting surface 212 located at the bottom of the mounting cavity 211. In the embodiment illustrated in this utility model, the mounting cavity 211 is cylindrical.

[0037] During assembly, the bottom of the liquid storage cylinder 11 is inserted into the mounting cavity 211. The first bottom surface 112 of the liquid storage cylinder 11 abuts against the mounting surface 212 of the mounting part 21 to achieve installation limitation. The second bottom surface 1422 of the bottom cover 14 is spaced a certain distance from the mounting surface 212, so that the second bottom surface 1422 of the bottom cover 14 does not abut against the mounting surface 212, thereby preventing external forces from being applied to the bottom cover 14 and damaging the first annular weld 143, reducing the risk of failure. The mounting surface 212 is a complete surface, that is, it does not have any perforations penetrating the mounting surface 212, in order to improve the overall rigidity and avoid liquid accumulation in the subsequent electrophoresis process.

[0038] In one embodiment of this utility model, the liquid storage cylinder 11 and the mounting part 21 are fitted with a clearance to facilitate assembly. In the embodiment illustrated in this utility model, the top of the mounting part 21 is provided with a second annular weld 213 for welding to the liquid storage cylinder 11.

[0039] In the embodiment illustrated in this utility model, the bottom of the first support portion 22 is provided with a first mounting hole 221 penetrating the first support portion 22, and the bottom of the second support portion 23 is provided with a second mounting hole 231 penetrating the second support portion 23. The first mounting hole 221 and the second mounting hole 231 are aligned. In the embodiment illustrated in this utility model, both the first mounting hole 221 and the second mounting hole 231 are circular holes. In the embodiment illustrated in this utility model, both the first valve housing 12 and the second valve housing 13 are located near the lower part of the liquid storage cylinder 11.

[0040] In the embodiment illustrated in this utility model, the mounting part 21, the first bracket part 22, and the second bracket part 23 are integrally formed. Preferably, the second housing 2 is forged from low-carbon high-alloy steel to reduce its weight while still meeting the requirements for bearing suspension loads.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of this specification should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
