[0002] A vibration damper is a device that suppresses vibration by converting mechanical vibration energy into heat energy or other forms of energy. Its core function is to apply a damping force opposite to the direction of vibration, reducing the vibration amplitude and accelerating energy dissipation.

[0003] Existing vibration dampers include mounting modules that provide support and connection. These mounting modules have the following problems: they consist of valve seats, sealing plates, pressure plates, and cover plates. The connection between components is achieved through methods such as cover plate clamping and welding, resulting in unreliable sealing. The number of components is large, leading to high economic costs. Furthermore, the valve seats are difficult to process, resulting in high costs for mass production.

[0009] The substrate has a channel structure to allow fluid to flow within the sub-cavity and form a flow loop for coupling fluid into the valve body;

[0010] Correspondingly, one end of the sub-cavity is connected to the outside and used to install the valve body.

[0012] The sub-cavity has an open end and a closed end, and the valve body is inserted into the sub-cavity through the open end of the sub-cavity.

[0013] The sub-cavity is equipped with a sealing part. When the valve body is installed on the sub-cavity, the sub-cavity is divided into two sub-regions by the sealing part. Among the two sub-regions, the one with the open end adjacent to the sub-cavity is constructed as the outer region and the other is constructed as the inner region.

[0015] In one possible design, the channel structure includes a first fluid channel disposed on the substrate, a second fluid channel disposed on the partition, and a compensation channel;

[0016] The first fluid channel has two sections, each located in the inner region of one of the sub-cavities; the second fluid channel connects the outer regions of the two sub-cavities, allowing fluid from one sub-cavity to flow into the other sub-cavity through the second fluid channel.

[0017] Two first fluid channels are connected through a second fluid channel to form a flow loop, and correspondingly, the flow loop has one flow loop;

[0025] Two sixth fluid channels are provided and located on the lower bearing surface. The two sixth fluid channels are respectively connected to the outer area of ​​one of the sub-cavities.

[0026] The fifth and sixth fluid channels located on the same sub-cavity form a flow loop, and correspondingly, the flow loop has two channels.

[0027] In one possible design, both the upper and lower bearing surfaces of the substrate are provided with snap-fit ​​structures, which are used to form slots for connecting other components.

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0049] Example:

[0050] like Figure 1 As shown, a vibration damper includes a damper body, a damping valve 30, and a lower connecting part 40;

[0051] The damper body includes an outer tube 20 and a damping rod 50. The outer tube 20 has two opposite ends, one end of which is provided with the damping rod 50, and the other end is connected to the lower connection part 40 through an intermediate module. Accordingly, the damping rod 50 slides back and forth along the outer tube 20 to drive fluid flow.

[0052] Two damping valves 30 are provided and are respectively installed on the two sub-cavities 103 of the intermediate module.

[0053] The outer tube 20 is connected to the lower connecting part 40 via an intermediate module, and the damping valve 30 is inserted into the intermediate module, that is, the damping valve 30 passes through the corresponding sub-cavity 103. Thus, the intermediate module connects the various components, enabling them to interact and achieve the designed functions and desired effects.

[0054] The vibration damper described herein, while achieving its design principles and functions, reduces the total number of components, effectively lowering the economic costs of the manufacturing process. Furthermore, the use of intermediate modules to connect other components, with these modules integrally molded, eliminates the need for welding or other additional processing, effectively avoiding problems such as component deformation and assembly tolerance variations caused by extra processing, thus significantly improving the product yield. Based on this, the vibration damper, through structural improvements, optimizes and enhances the manufacturing process, not only reducing economic costs but also increasing the yield rate, effectively improving the market competitiveness of the vibration damper.

[0055] For additional processing such as welding, the components are reheated during the process, the heat-affected zone is uncontrollable, thermal deformation is prone to occur at the joints, affecting assembly tolerances and reducing product yield.

[0056] During operation, the damper body works, causing the damping rod 50 to slide back and forth in the outer tube 20, thereby driving the working medium in the vibration damper to flow. The working medium flows back and forth along the flow channel in the vibration damper, achieving the purposes of vibration reduction, noise reduction, improved stability, and control of action time.

[0057] It is easy to understand that the flow channel in the vibration damper can be set on a component, such as a hole structure opened on the intermediate module, or it can be a gap between adjacent components, such as the gap between the outer tube 20 and the damping rod 50, or the gap between the damping valve 30 and the intermediate module.

[0058] The following is combined Figures 1-9 To further explain the intermediate module, specifically:

[0059] An intermediate module includes a base 10;

[0060] The base 10 has a cavity 101 and a partition 102 for separating the cavity 101. Accordingly, the cavity 101 is divided into two sub-cavities 103.

[0061] The base 10 is provided with a channel structure to allow fluid to flow in the sub-cavity 103 and form a flow loop for coupling fluid into the valve body;

[0062] Accordingly, one end of the sub-cavity 103 is connected to the outside and is used to install the valve body.

[0063] In the intermediate module, the base 10 can be constructed into any suitable shape to adapt to different usage environments, improving the practicality of the intermediate module. The base 10 is machined to form a sub-cavity 103 for mounting the valve body. Simultaneously, a channel structure is formed to create a flow path, allowing the working fluid to flow back and forth along the designed direction. The intermediate module preferably utilizes any suitable existing one-piece molding process to improve its overall integrity, simplifying processing and facilitating mass production.

[0064] It is easy to understand that when the intermediate module is used for the vibration damper, the valve body inserted into the sub-cavity 103 is the damping valve 30. When the intermediate module is used for other equipment, the valve body inserted into the sub-cavity 103 can also be any other suitable existing control valve.

[0065] When the intermediate module is used in the vibration damper, the flow of the working medium can be divided into flow along a first direction and flow along a second direction, with the first and second directions being opposite to each other, to achieve cyclic flow of the working medium in the vibration damper. Based on this, a damping valve 30 is provided in each direction to achieve functions such as vibration reduction, noise reduction, improved stability, and control of action time. A total of two damping valves 30 are required. Correspondingly, two sub-cavities 103 are provided on the base 10.

[0066] In one possible implementation, the substrate 10 has opposing upper and lower bearing surfaces, both of which are closed.

[0067] The sub-cavity 103 has an open end and a closed end, and correspondingly, the valve body is inserted into the sub-cavity 103 through the open end of the sub-cavity 103;

[0068] The sub-cavity 103 is provided with a sealing part 114. When the valve body is installed on the sub-cavity 103, the sub-cavity 103 is divided into two sub-regions by the sealing part 114. Among the two sub-regions, one of the open ends of the sub-cavity 103 is constructed as the outer region 115, and the other is constructed as the inner region 116.

[0069] Accordingly, the channel structure includes at least two fluid channels, with at least one fluid channel provided on both the outer zone 115 and the inner zone 116.

[0070] Based on the above design scheme, the upper and lower bearing surfaces of the base 10 are sealed to prevent the working medium from flowing out and reduce the probability of leakage at the component connection. For the sub-cavity 103, the valve body passes through the open end and moves towards the closed end. The gap between the valve body end and the closed end can be adjusted according to the usage.

[0071] When the valve body is inserted into the sub-cavity 103, a sealing part 114 is provided in the sub-cavity 103 to improve the stability of the connection and increase the contact area between the valve body and the sub-cavity 103. At the same time, through the cooperation between the valve body and the sealing part 114, the sub-cavity 103 is divided into two sub-regions, namely the outer region 115 and the inner region 116, so that the valve body can also be used to construct the fluid channel, ensuring that the working fluid flows in the designed direction, and also helping to reduce the processing of the base body 10.

[0072] Optionally, such as Figures 1-3 As shown, the open end of the sub-cavity 103 is constructed as a mounting hole for connecting to the valve body, and the mounting hole is provided with a connecting thread, that is, the connecting thread is located on the outer area 115. Based on this, the sub-cavity 103 is connected to the valve body through a threaded connection. The connection structure is simple and easy to disassemble and assemble; and when necessary, a seal can be achieved through the threaded structure to prevent leakage of the working fluid.

[0073] Regarding the channel structure, the intermediate module is designed with various types of channel structures for different usage scenarios, allowing staff to choose the appropriate type. Specifically:

[0074] Case 1: For example Figures 2-4 As shown, the channel structure includes a first fluid channel 106 disposed on the substrate 10, a second fluid channel 107 disposed on the partition 102, and a compensation channel 108.

[0075] The first fluid channel 106 has two channels and is located on the inner region 116 of one of the sub-cavities 103 respectively; the second fluid channel 107 is used to connect the outer regions 115 of the two sub-cavities 103 so that the fluid in one of the sub-cavities 103 flows to the sub-cavity 103 through the second fluid channel 107.

[0076] The two first fluid channels 106 are connected through the second fluid channel 107 and form a flow loop, and correspondingly, the flow loop has one flow loop;

[0077] The compensation channel 108 is located on the outer area 115 of any sub-cavity 103 and is used to compensate for fluid.

[0078] Based on the above design, for the working fluid flowing into the intermediate module, when the working fluid flows in the first direction, under the action of the damping rod 50, the working fluid in the outer tube 20 flows from one of the two first fluid channels 106 into the corresponding sub-cavity 103. Correspondingly, the damping valve 30 on the corresponding sub-cavity 103 is activated. The working fluid flows into the outer area 115 and then into the other sub-cavity 103 through the second fluid channel 107, and then flows back to the outer tube 20 through the other first fluid channel 106. When the damping rod 50 moves in the opposite direction, the working fluid flows in the opposite direction of the above flow.

[0079] In this implementation scheme, the second fluid channel 107 serves as a common flow channel, allowing the working fluid to return to the outer tube 20 without causing idle movement of the damping rod 50 or related effects. Correspondingly, a compensation channel 108 is also provided to compensate for volume changes during operation.

[0080] Case 2: For example Figure 5 and Figure 6 As shown, the channel structure includes a third fluid channel 109 and a fourth fluid channel 110;

[0081] The third fluid channel 109 has two sections, each located on the inner region 116 of one of the sub-cavities 103;

[0082] Two fourth fluid channels 110 are provided and located on the upper bearing surface 104. The two fourth fluid channels 110 are respectively connected to the outer area 115 of one of the sub-cavities 103.

[0083] The third fluid channel 109 and the fourth fluid channel 110, located on the same sub-cavity 103, form a flow loop, and correspondingly, the flow loop has two channels.

[0084] Based on the above design, each sub-cavity 103 is provided with two fluid channels: a third fluid channel 109 and a fourth fluid channel 110. The working fluid flows into the corresponding sub-cavity 103 from one of the third fluid channel 109 and the fourth fluid channel 110, and then flows out of the corresponding sub-cavity 103 from the other, so that the two sub-cavities 103 can work independently. In addition, the fourth fluid channel 110 can also be used as a compensation channel to compensate for volume changes during operation.

[0085] Case 3: For example Figures 7-9 As shown, the channel structure includes a fifth fluid channel 111 and a sixth fluid channel 112;

[0086] The fifth fluid channel 111 has two sections, each located on the inner region 116 of one of the sub-cavities 103;

[0087] Two sixth fluid channels 112 are provided and located on the lower bearing surface 105. The two sixth fluid channels 112 are respectively connected to the outer area 115 of one of the sub-cavities 103.

[0088] The fifth fluid channel 111 and the sixth fluid channel 112, located on the same sub-cavity 103, form a flow loop, and correspondingly, the flow loop has two channels.

[0089] Based on the above design scheme, the implementation scheme of Case 3 is similar to that of Case 2, that is, each sub-cavity 103 is connected to two fluid channels so that each sub-cavity 103 can work independently. The difference between Case 3 and Case 2 is that the fourth fluid channel 110 and the sixth fluid channel 112 are located in different positions, that is, the fourth fluid channel 110 is located on the upper bearing surface 104, and the sixth fluid channel 112 is located on the lower bearing surface 105, so that the flow path of the working fluid is different. Based on this, for the working fluid, Case 2 can achieve oil-gas mixing, while Case 3 can achieve oil-gas isolation, effectively avoiding the problem of oil foaming.

[0090] Furthermore, Case 1 is similar to Case 2, and it is also a mixed oil and gas scheme.

[0091] In one possible implementation, the upper bearing surface 104 and the lower bearing surface 105 of the base 10 are provided with snap-fit ​​structures 113, which are used to form a slot for connecting other components.

[0092] Based on the above design scheme, the outer tube 20 or the lower connecting part 40 is connected by the snap-fit ​​structure 113. Taking the outer tube 20 as an example, the snap-fit ​​structure 113 is used to achieve centering. The upper and lower snap-fit ​​structures 113 cooperate with each other to achieve simultaneous centering of the upper and lower parts.

[0093] Optionally, the snap-fit ​​structure 113 can be constructed in any suitable shape, such as a protruding baffle or a concave arc groove, and can be set in any suitable number, allowing for flexible and diverse configurations to adapt to different usage scenarios.

[0094] The vibration damper includes the intermediate module, as well as the damper body, damping valve 30 and lower connection part 40;

[0095] The damper body includes an outer tube 20 and a damping rod 50. The outer tube 20 has two opposite ends, one end of which is provided with the damping rod 50, and the other end is connected to the lower connection part 40 through the intermediate module. Accordingly, the damping rod 50 slides back and forth along the outer tube 20 to drive fluid flow.

[0096] Two damping valves 30 are provided and are respectively installed on the two sub-cavities 103 of the intermediate module.

[0097] The structure and function of the vibration damper have been described in conjunction with the specific structure of the intermediate module, and will not be repeated here. Furthermore, in one possible implementation, the two damping valves 30 are arranged parallel to each other and side by side, and correspondingly, the axes of the two sub-cavities 103 are parallel to each other and located on the same plane; the axis of the damping rod 50 is perpendicular to the plane containing the axes of the two sub-cavities 103.

[0098] Based on the above design scheme, by restricting the position of each component, the structure of the vibration damper is made more compact and the space utilization rate is higher. When the vibration damper is used in confined spaces such as automobile suspension, it can effectively reduce the space occupation of the vibration damper and make the installation more flexible and convenient.

[0099] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
