Description

Technical Field

[0001] This utility model relates to the field of electronically controlled vibration dampers, and in particular to an external CDC electronically controlled vibration damper. Background Technology

[0002] The vehicle suspension system is a key factor in determining the vehicle's ride comfort and handling stability. Currently, the mainstream adjustable damping shock absorbers on the market are divided into CDC shock absorbers with built-in solenoid valves and CDC shock absorbers with external solenoid valves.

[0003] In existing external CDC electronically controlled vibration dampers, users typically use bolts to connect the solenoid valve to the outside of the damper. Since bolt installation requires tools, is time-consuming, and the bolts are prone to rusting and aging, it is difficult for users to install quickly, which undoubtedly affects the user's use and installation speed. Therefore, we propose an external CDC electronically controlled vibration damper to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an external CDC electronically controlled vibration damper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An external CDC electronically controlled vibration damper includes: a damping cylinder, a piston slidably connected to the inner side of the damping cylinder, and a mounting base fixedly connected to the outer side of the damping cylinder. A solenoid valve is movably inserted into the inner side of the mounting base, and locking blocks are slidably connected to the inner walls of both sides of the mounting base. A connecting block is fixedly connected to one side of each locking block, and a connecting rod is rotatably connected to the front side of each connecting block. A rotating frame is rotatably connected to the front side of the mounting base, and the other ends of each connecting rod are rotatably connected to the inner side of the rotating frame. A rotating shaft is fixedly connected to the front side of the rotating frame, and the outer side of the rotating shaft is rotatably connected to the inner side of the mounting base.

[0007] Preferably, the mounting base has a circular groove on its front side, a handwheel is rotatably connected to the inner side of the circular groove, and the inner side of the handwheel is fixedly connected to the outer side of the rotating shaft. A circular shaft is fixedly connected to the inner wall of the rear side of the circular groove, and an L-shaped block is slidably connected to the outer side of the circular shaft. Two locking holes adapted to the L-shaped block are opened on the inner side of the handwheel, and the outer side of the L-shaped block is movably inserted into the inner side of the corresponding locking hole. A second spring is fixedly connected to the rear side of the L-shaped block, and the other end of the second spring is fixedly connected to the inner wall of the rear side of the circular groove.

[0008] Preferably, a fixing rod is provided on the outer side of the vibration damping cylinder, and a first groove and a second groove are opened on the inner side of the fixing rod. A first rod and a second rod are slidably connected to the inner sides of the first groove and the second groove, respectively. The left side of the first rod is fixedly connected to the right side of the piston, and a small spring is fixedly connected to the right side of the piston. The other end of the small spring is fixedly connected to the left side of the fixing rod.

[0009] Preferably, a fixed base is fixedly connected to the right side of the second rod, and a first spring is fixedly connected to the left side of the fixed base. The other end of the first spring is fixedly connected to the right side of the vibration damper, and two small brackets are fixedly connected to the right side of the fixed base.

[0010] Preferably, the left side of the vibration damping cylinder is fixedly connected to two large brackets.

[0011] Preferably, guide blocks are fixedly connected to the inner walls on both sides of the mounting base, and the outer sides of the two guide blocks are slidably connected to the inner side of the corresponding connecting block.

[0012] In this utility model, an external CDC electronically controlled vibration damper is installed inside the corresponding equipment using a large bracket and a fixed base. When installing the solenoid valve and the vibration damper, the solenoid valve is inserted into the mounting base. The user can connect the solenoid valve and the vibration damper to the corresponding oil circuit as needed. This process is the same as the operation in actual application. When installing the solenoid valve, the L-shaped block is pushed outward, causing the second spring to stretch. Then the L-shaped block begins to slide, and then the L-shaped block leaves the inside of the handwheel. Then the rotating shaft begins to rotate, which causes the rotating frame to rotate. Then the connecting rod begins to rotate, which causes the connecting block to move horizontally. Then the connecting block drives the locking block to insert into the inside of the solenoid valve.

[0013] In this utility model, an external CDC electronically controlled vibration damper is installed by moving an L-shaped block to another corresponding locking hole. The user inserts the L-shaped block into the corresponding locking hole, thus completing the installation of the solenoid valve and the vibration damping cylinder. This avoids the need for a large number of bolts in traditional installation. When the device is working, the piston begins to slide and compresses the small spring. Furthermore, the piston presses the fixing rod, causing the fixing rod to slide outside the second rod. At this time, the first spring begins to compress, thereby performing vibration damping. In addition, the solenoid valve adjusts the internal oil circuit to further help the device complete vibration damping. This process is the same as that of a shock absorber in actual application.

[0014] This utility model has a reasonable structural design. Through the cooperation between the connecting rod, connecting block and mounting base, the solenoid valve and the vibration damper can be easily fixed together. This allows users to quickly complete the installation work, further improving the installation speed and making it easier for users to use. Attached Figure Description

A second spring 18 is fixedly connected to the rear side of the L-shaped block 17, and the other end of the second spring 18 is fixedly connected to the inner wall of the rear side of the circular groove. A fixing rod 3 is provided on the outer side of the vibration damping cylinder 1, and a first groove and a second groove are provided on the inner side of the fixing rod 3. A first rod 4 and a second rod 5 are slidably connected to the inner sides of the first groove and the second groove, respectively. The left side of the first rod 4 is fixedly connected to the right side of the piston 2, and a small spring is fixedly connected to the right side of the piston 2. The other end of the small spring is fixedly connected to the left side of the fixing rod 3, which facilitates the device to perform vibration damping.

[0024] In this embodiment, a fixed seat 6 is fixedly connected to the right side of the second rod 5, and a first spring 7 is fixedly connected to the left side of the fixed seat 6. The other end of the first spring 7 is fixedly connected to the right side of the vibration damping cylinder 1.

[0025] In this embodiment, during use, the device is installed inside the corresponding equipment using the large bracket 9 and the fixed base 6.

Furthermore, the piston 2 presses the fixing rod 3, causing the fixing rod 3 to begin to slide outside the second rod 5. At this time, the first spring 7 begins to compress, thereby performing a vibration damping effect. In conjunction with the solenoid valve 10 to adjust the internal oil circuit, it further helps the device to complete the vibration damping. This process is the same as that of the shock absorber in actual application.
