DETAILED DESCRIPTION

[0032] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0034] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0035] In the prior art, the working principle of the intermediate cylinder of an electronically controlled shock absorber is to provide an oil passage from the working cylinder to the solenoid valve. Therefore, the two ends of the intermediate cylinder are grooved. These grooves are used to accommodate two elastic components to close the oil circuit. The working cylinder is provided with several holes, one of which must be installed through the working cylinder hole. This is prone to damage and is difficult to detect, causing the shock absorber's electronic control function to fail. This structure also makes it easy for elastic components to be missing and difficult to detect and troubleshoot. The existing concave grooves on both ends of the intermediate cylinder are difficult to form, precision control, and dimensional measurement, posing a high risk of failure. Furthermore, the existing elastic component mounting grooves are located on both sides of the intermediate cylinder. The U-shaped grooves formed by the intermediate cylinder are difficult to hydraulically form and precisely control, and are prone to deviations. The precision can only be guaranteed to within ±(0.08-0.1) mm, which is not conducive to the elastic component's fit and may even cause oil leakage. Furthermore, the cost of hydraulic mold forming is high. The new solution allows the dimensions of the U-shaped grooves in the guide to be controlled to ±0.05, resulting in better shock absorber stability and lower powder metallurgy component costs. In the prior art, the elastic member is installed inside the groove, making it easy to miss and difficult to identify. In the prior art, the U-shaped groove and elastic member are both located outside the guide and compression valve seat, making them more visible, less likely to miss, and easier to identify. In the prior art, the two elastic members at the upper and lower ends of the assembly are already built into the groove of the middle cylinder. During assembly, one of the elastic members must pass through the oil flow hole of the working cylinder, which can easily cause pressure release when the elastic member passes through the hole, causing the elastic member to rebound and squeeze the elastic member, resulting in damage to the elastic member and causing the electronic control function of the electronically controlled shock absorber to fail.

[0036] The present utility model provides an electronically controlled shock absorber cylinder structure, which differs from the prior art in that an intermediate cylinder can be arranged between the oil storage cylinder and the working cylinder, with its upper and lower ends respectively extending to the guide and the compression valve seat and maintaining an appropriate amount of clearance therewith. The guide and the compression valve seat are respectively provided with a mounting groove for placing an elastic component, and the elastic component is more easily identified on the outside, thereby solving the problem of easy missing installation of the elastic component. The elastic component is assembled on the outside to avoid passing through the oil flow hole on the working cylinder, which can greatly protect the elastic component from damage, thereby reducing the failure of the electronically controlled shock absorber. Placing the mounting groove on the guide and the bottom valve makes it easier to ensure the accuracy of the processing of the elastic component and easy to measure, thereby improving the simplicity and cost of the overall solution of the electronically controlled shock absorber. At the same time, a working cylinder mounting seat is designed to die-cast the inner wall of the working cylinder and the side wall of the guide. The structural details provided by the present utility model will be specifically explained below.

[0037] See Figure 1-8, shown is the cylinder structure of the electronically controlled shock absorber of the present invention. The cylinder structure of the electronically controlled shock absorber of the present invention includes a cylinder assembly 10, a guide assembly 20, a compression valve assembly 30 and an elastic assembly 40. Cylinder assembly 10, cylinder assembly 10 includes an intermediate cylinder 11 and a working cylinder 12, the intermediate cylinder 11 and the working cylinder 12 are coaxially arranged in parallel and radially spaced a certain distance apart. The guide assembly 20 is provided at one end of the cylinder assembly 10, and the guide assembly 20 includes a guide assembly body 21, a first mounting groove 22 and a working cylinder body mounting seat 23, the first mounting groove 22 and the working cylinder body mounting seat 23 are respectively circumferentially provided on the outer surface of the side wall of the first end of the guide assembly body 21. The compression valve assembly 30 is located at the other end of the cylinder assembly 10, away from the guide assembly 20. It includes a compression valve body 31, a second mounting groove 32, and a compression valve mounting seat 33. The second mounting groove 32 and the compression valve mounting seat 33 are circumferentially arranged on the outer sidewall surface of the first end of the compression valve body 31. The elastic assembly 40 includes a first elastic member 41 and a second elastic member 42. The first elastic member 41 is positioned within the first mounting groove 22, and the second elastic member 42 is positioned within the second mounting groove 32. The intermediate cylinder 11 is sleeved at both ends over the first end of the guide assembly 20 and the first end of the compression valve assembly 30, respectively. The first elastic member 41 seals the gap between the intermediate cylinder 11 and the guide assembly body 21, and the second elastic member 42 seals the gap between the intermediate cylinder 11 and the compression valve body 31. The working cylinder 12 is sleeved at both ends over the outer surfaces of the working cylinder mounting seat 23 and the compression valve mounting seat 33, respectively.

[0038] like Figure 1 、 2Figure 2 is a schematic diagram of the cylinder structure of the electronically controlled shock absorber provided by the present invention. In this embodiment, the cylinder structure includes a cylinder assembly 10, a guide assembly 20, a compression valve assembly 30, and an elastic assembly 40. The cylinder assembly 10 comprises an intermediate cylinder 11, a working cylinder 12, and an oil storage cylinder 13. The intermediate cylinder 11, the working cylinder 12, and the oil storage cylinder 13 are positioned parallel to each other and spaced a certain distance apart. The oil storage cylinder 13 is located at the outermost portion, the intermediate cylinder 11 is located in the middle, and the working cylinder 12 is located at the innermost portion. The guide assembly 20 and the compression valve assembly 30 are respectively provided at both ends of the cylinder assembly 10. The intermediate cylinder 11, the working cylinder 12, and the oil storage cylinder 13 are fixedly connected to the guide assembly 20 and the compression valve assembly 30, respectively. The guide assembly 20 is located at one end of the cylinder assembly 10 and includes a guide assembly body 21, a first mounting slot 22, and a working cylinder body mounting seat 23. The first mounting slot 22 and the working cylinder body mounting seat 23 are respectively located on the sidewalls of the guide assembly body 21. The compression valve assembly 30 is located at the other end of the cylinder assembly 10 away from the guide assembly 20. The compression valve assembly 30 includes a compression valve body 31, a second mounting slot 32, and a compression valve mounting seat 33. The second mounting slot 32 and the compression valve mounting seat 33 are respectively located on the sidewalls of the compression valve body 31. The working cylinder 12 is also provided with a working cylinder oil flow hole 121.

[0039] like Figure 1 、 3 As shown, the elastic assembly 40 includes a first elastic member 41 and a second elastic member 42. The first elastic member 41 is positioned in the first mounting groove 22, and the second elastic member 42 is positioned in the second mounting groove 32. The first and second elastic members 41 and 42 are ring-shaped solid rubber structures. They are positioned at opposite ends of the intermediate cylinder 11, covering the first and second mounting grooves 22 and 32, respectively. The thickness of the first and second elastic members 41 and 42 is greater than the depth of the first and second mounting grooves 22 and 32. Therefore, when the first and second elastic members 41 and 42 are positioned in the first and second mounting grooves 22 and 32, respectively, the outer diameters of the first and second elastic members 41 and 42 are greater than the inner diameter of the intermediate cylinder 11. When the intermediate cylinder 11 is sleeved onto the guide assembly body 21, the inner wall of the intermediate cylinder 11 forms an interference fit with the first and second elastic members 41 and 42, respectively. Consequently, the first and second elastic members 41 and 42 secure the intermediate cylinder 11 to the guide assembly 20 and the compression valve assembly 30, respectively, through the first and second elastic members 41 and 42.

[0040] like Figure 4 、 5As shown in Figure 6, the working cylinder body mounting base 23 includes a working cylinder body mounting member 231, a working cylinder body guide member 232, and a working cylinder body mounting wall 233. The working cylinder body mounting member 231 extends vertically along the side wall of the guide assembly 20, and the working cylinder body guide member 232 extends from the working cylinder body mounting member 231 toward the working cylinder body 12. Both sides of the working cylinder body guide member 232 are inclined relative to the working cylinder body 12, which facilitates the assembly of components. At the same time, the end of the working cylinder body 12 abuts against the working cylinder body mounting member 231, and the inner wall of the working cylinder body 12 is die-cast and fixed to the working cylinder body mounting wall 233. The working cylinder body mounting member 231 and the working cylinder body mounting wall 233 simultaneously fix the working cylinder body 12. At the same time, an oil storage cylinder 13 is provided outside the intermediate cylinder 11. The intermediate cylinder 11 is arranged between the oil storage cylinder 13 and the working cylinder 12. The oil storage cylinder 13, the intermediate cylinder 11 and the working cylinder 12 are coaxially arranged in parallel and spaced a certain distance apart.

[0041] like Figure 1 、 6 Figures 7 and 8 are schematic diagrams of the cylinder structure of an expanded embodiment of the present invention. In this embodiment, the first mounting groove 22 on the guide assembly 20 is replaced by a first stopper 24 and a second stopper 24'. Specifically, the first stopper 24 and the second stopper 24' sandwich the first elastic member 41 therebetween to retain and secure it. The second mounting groove 32 on the compression valve assembly 30 is formed by a third stopper 34 and the side of the compression valve 31 corresponding to the second elastic member 42. Specifically, the third stopper 32 and the corresponding side of the compression valve 31 retain and secure the second elastic member 42. The other structures remain unchanged from those of the original embodiment. The advantage of using stoppers instead of grooves is that the stopper structure can be freely selected. While the materials used for the guide assembly body 21 and the compression valve body 31 generally have poor structural strength, making them difficult to secure, the stoppers can be made of a stronger material. Furthermore, the stoppers can be removed at any time without affecting the overall structure of the device. The stoppers are also less expensive to produce and easier to secure, saving significant labor costs compared to slotting.

[0042] The utility model provides an electric shock absorber cylinder structure, in which the intermediate cylinder is arranged between the oil storage cylinder and the working cylinder, and the upper and lower ends thereof extend to the guide and the compression valve seat respectively and maintain an appropriate amount of clearance therefrom. The guide and the compression valve seat are respectively provided with a mounting groove for placing the elastic component, and the elastic component is more easily identified on the outside, thereby solving the problem of the elastic component being easily missed. The elastic component is assembled on the outside to avoid passing through the oil flow hole on the working cylinder, which can greatly protect the elastic component from damage, thereby reducing the failure of the electric shock absorber. Placing the mounting groove on the guide and the bottom valve makes it easier to ensure the accuracy of the processing of the elastic component and easy to measure, thereby improving the simplicity and cost of the overall solution of the electric shock absorber. At the same time, a working cylinder mounting seat is designed to die-cast the inner wall of the working cylinder and the side wall of the guide.

[0043] Therefore, the electronically controlled shock absorber cylinder structure of the present invention can solve the problem in the prior art that elastic components are easily damaged and difficult to detect, which causes the electronically controlled adjustment function of the shock absorber to fail.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
