Abstract
Description
Technical Field
[0001] This utility model relates to the field of linear vibration actuator technology, specifically to an integrated damping structure for a linear vibration actuator. Background Technology
[0002] The integrated vibration damping structure of a linear vibration actuator combines linear drive functionality with vibration damping functionality, achieving a highly efficient integrated drive and vibration control system through structural integration and collaborative design. Existing linear vibration actuators directly install spring dampers under the base plate to mitigate the vibration impact on external equipment during operation.
[0003] However, after prolonged use, the internal springs of the spring damper need to be replaced. Since the springs are installed inside the groove, and the base plate of the linear vibration actuator and the top plate of the spring damper are shared, and a transmission line is installed at the top of the linear vibration actuator, replacing the springs is quite laborious when the linear vibration actuator is difficult to disassemble. Therefore, an integrated damping structure for the linear vibration actuator is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an integrated vibration damping structure for a linear vibration actuator, thereby solving the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is an integrated vibration damping structure for a linear vibration actuator, comprising:
[0006] A spring shock absorber includes a base plate, a supporting channel steel, a top plate, a mounting groove, and a spring. The supporting channel steel is welded to both ends of the base plate. The top plate is movably connected to the upper end of the supporting channel steel by bolts. The mounting groove is fixed to the lower end of the top plate by bolts. The upper end of the spring is placed in the mounting groove, and the lower end is attached to the upper end of the base plate.
[0007] The movable component includes a threaded hole, an adjusting screw, a limiting arc plate, a limiting plate, and a limiting hole. The threaded hole is located on the lower side of the supporting channel steel. The adjusting screw is screwed into the threaded hole. The limiting arc plate is rotatably connected to one end of the adjusting screw. The limiting plate is fixed in the middle of the lower end of the limiting arc plate. The limiting hole is located in the middle of the base plate and between the two supporting channel steels.
[0008] Furthermore, when the limiting plate moves to the end of the limiting hole away from the supporting channel steel, the two limiting arc plates come into contact.
[0009] Furthermore, when the two limiting arc plates are in contact, they are located in the center of the base plate, and their inner sides are in contact with the outer side of the lower end of the spring.
[0010] Furthermore, the spring damper also includes a damping pad, which is fixed to the lower end of the base plate.
[0011] Furthermore, it also includes a limiting component, which includes a U-shaped connector and a baffle. The U-shaped connector is fixed to both ends of the inner side of the support channel steel, and both ends of the baffle are respectively inserted into the two U-shaped connectors.
[0012] Furthermore, the limiting component also includes a rubber block and a countersunk hole, the countersunk hole being formed in the middle of the rubber block, and the rubber block being fixed to both ends of the baffle by countersunk screws.
[0013] Furthermore, the limiting component also includes an opening, which is located in the middle of the baffle.
[0014] This utility model has the following beneficial effects:
[0015] This invention utilizes a movable component. When a spring needs replacement, rotating the adjusting screw in the threaded hole moves it along the threaded hole towards the outside of the support channel steel. This causes the limiting arc plate to approach the support channel steel, and the limiting plate below the limiting arc plate moves along the limiting hole. When the two limiting arc plates are in contact with the support channel steel, the lower end of the spring is exposed. Then, rotating the nut above the mounting slot moves the mounting slot upward, exposing the upper end of the spring. At this point, the spring can be easily removed. This design facilitates spring assembly and disassembly, improving production efficiency. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] Please see Figure 1-3 As shown, this utility model is an integrated vibration damping structure for a linear vibration actuator, comprising:
[0026] The spring shock absorber includes a base plate 10, a support channel steel 12, a top plate 13, a mounting groove 14, and a spring 15. The support channel steel 12 is welded to the upper two ends of the base plate 10. The top plate 13 is movably connected to the upper end of the support channel steel 12 by bolts. The mounting groove 14 is fixed to the lower end of the top plate 13 by bolts. The upper end of the spring 15 is placed in the mounting groove 14, and the lower end is attached to the upper end of the base plate 10.
[0027] The spring shock absorber also includes a shock-absorbing pad 11, which is fixed to the lower end of the base plate 10;
[0028] The base plate 10 provides support, the shock-absorbing pad 11 provides shock absorption, the support channel steel 12 provides support and limit, the top plate 13 provides support and is used to support the linear vibration actuator above, and the mounting groove 14 is used to install the spring 15, which can absorb the energy generated by vibration.
[0029] The movable component includes a threaded hole 20, an adjusting screw 21, a limiting arc plate 22, a limiting plate 23, and a limiting hole 24. The threaded hole 20 is opened on the lower side of the supporting channel steel 12. The adjusting screw 21 is screwed into the threaded hole 20. The limiting arc plate 22 is rotatably connected to one end of the adjusting screw 21. The limiting plate 23 is fixed in the middle of the lower end of the limiting arc plate 22. The limiting hole 24 is opened in the middle of the base plate 10 and is located between the two supporting channel steels 12.
[0030] When the limiting plate 23 moves to one end of the limiting hole 24 away from the supporting channel steel 12, the two limiting arc plates 22 come into contact.
[0031] When the two limiting arc plates 22 are in contact, they are located in the center of the base plate 10, and their inner sides are in contact with the outer side of the lower end of the spring 15.
[0032] The threaded hole 20 and the adjusting screw 21 serve an adjustment function, the limiting arc plate 22 serves a limiting function and is used to wrap the lower end of the spring 15, and the limiting plate 23 and the limiting hole 24 serve a limiting function to prevent the limiting arc plate 22 from shifting position when it moves.
[0033] Working principle:
[0034] When it is necessary to replace spring 15, rotate the adjusting screw 21 in the threaded hole 20 to move the adjusting screw 21 along the threaded hole 20 to the outside of the support channel steel 12, thereby driving the limiting arc plate 22 to approach the support channel steel 12. The limiting plate 23 below the limiting arc plate 22 moves along the limiting hole 24. When the two limiting arc plates 22 are in contact with the support channel steel 12, the lower end of spring 15 is exposed. Then rotate the nut above the mounting groove 14, and the mounting groove 14 can be moved upward. At this time, the upper end of spring 15 is exposed, and spring 15 can be easily removed.
[0035] This step facilitates the assembly and disassembly of spring 15, improving production efficiency.
[0036] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0037] The limiting component includes a U-shaped connector 30 and a baffle 31. The U-shaped connector 30 is fixed to both ends of the inner side of the support channel steel 12, and both ends of the baffle 31 are respectively inserted into the two U-shaped connectors 30.
[0038] The limiting component also includes a rubber block 32 and a countersunk hole 33. The countersunk hole 33 is opened in the middle of the rubber block 32, and the rubber block 32 is fixed to both ends of the baffle 31 by countersunk screws.
[0039] The limiting component also includes an opening 34, which is located in the middle of the baffle 31;
[0040] The U-shaped connector 30 serves as a connector, the baffle 31 serves as a limiter, the rubber block 32 increases the frictional resistance between the U-shaped connector 30 and the baffle 31, the countersunk hole 33 is used to connect the screw, and the opening 34 facilitates the removal of the baffle 31 from the U-shaped connector 30, and the width of the opening 34 is smaller than the outer diameter of the adjusting screw 21.
[0041] Working principle:
[0042] When disassembling or assembling spring 15, pull baffle 31 upward from opening 34 with your finger to pull baffle 31 and rubber block 32 out of U-shaped connector 30. Rotate adjusting screw 21 to open limiting arc plate 22. After replacing spring 15, close limiting arc plate 22 and insert both ends of baffle 31 into U-shaped connector 30.
[0043] This step prevents the adjusting screw 21 from changing position due to vibration when the spring damper is working.
