Description

Technical Field

[0001] This utility model relates to the field of cinema equipment technology, specifically to an electric cylinder shock absorption structure. Background Technology

[0002] Electric cylinders are products specifically designed for continuous motion, low to high loads (usually high speeds), and can be used multiple times throughout their service life. These products have extremely high positioning accuracy and controllability, enabling precise motion control under loads ranging from a few kilograms to 50 tons.

[0003] When cinema seats are in use, the pedals are adjusted by electric cylinders. However, if the electric cylinder is subjected to a large pressure during the adjustment process, exceeding its set value, it can easily be damaged. However, the existing devices lack the function of protecting the electric cylinder, which reduces its service life.

[0004] Therefore, we propose an electric cylinder shock absorption structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing structure for an electric cylinder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric cylinder shock absorption structure, including a seat base and a pedal hinged to the seat base, wherein the bottom of the inner cavity of the seat base and the bottom of the pedal are hinged together with an electric cylinder body, and a mounting component is provided on the mounting base, and a protective component is provided on the top of the mounting base.

[0026] Example 1

[0027] Please see Figure 1-7 An electric cylinder shock absorption structure includes a seat base 1 and a pedal 2 hinged to the seat base 1. The bottom of the inner cavity of the seat base 1 and the bottom of the pedal 2 are hinged together with an electric cylinder body 3. Mounting components 6 are provided on the mounting base 4, and protective components 5 are provided on the top of the mounting base 4.

[0028] The protective assembly 5 includes a hinge plate 51 hinged to the top of the mounting base 4. A movable plate 52 is provided on the rear side of the hinge plate 51. An L-shaped column 53 is fixedly installed on the rear side of the movable plate 52. A semi-circular block 54 is fixedly installed on the opposite side of the L-shaped column 53. A damper 55 is fixedly installed on the rear side of the hinge plate 51 near both sides. The rear end of the damper 55 is fixedly connected to the movable plate 52. A damping spring 56 is movably sleeved on the outer periphery of the damper 55. The front and rear ends of the damping spring 56 are fixedly connected to the hinge plate 51 and the movable plate 52, respectively.

[0029] Specifically, when damping the electric cylinder body 3, if the electric cylinder body 3 experiences an instantaneous pressure greater than its designed value during use, the damping spring 56 and damper 55 can provide initial damping for the electric cylinder body 3.

[0030] A fixing block 521 is fixedly installed on the front side of the movable plate 52. Openings are provided on both sides of the fixing block 521. A fixing shaft 522 is fixedly installed at the top and bottom of the inner cavity of the opening. A trapezoidal block 523 is provided on the front side of the fixing shaft 522. A compression telescopic rod 524 is fixedly installed on the side of the trapezoidal block 523 that is far away from the top and bottom. A fixing plate 526 is fixedly installed at the end of the compression telescopic rod 524. A compression spring 525 is movably sleeved on the outer periphery of the compression telescopic rod 524. The two ends of the compression spring 525 are fixedly connected to the trapezoidal block 523 and the fixing plate 526 respectively.

[0031] Specifically, when the movable plate 52 moves forward, the trapezoidal block 523 can be moved to the side away from the fixed block 521 and the fixed shaft 522 in cooperation. This can compress the telescopic rod 524 and the compression spring 525, further buffering and shock-absorbing the electric cylinder body 3, preventing it from being damaged by excessive instantaneous force, and extending its service life.

[0032] The bottom of the inner cavity of the seat base 1 is provided with positioning grooves near both sides, and positioning blocks 8 are movably inserted into the inner cavity of each positioning groove.

[0033] Specifically, by setting the positioning block 8 to be movably inserted into the inner cavity of the positioning groove, it is convenient to install it stably in the future.

[0034] The outer periphery of the electric cylinder body 3 is fixedly fitted with retaining rings 7 near the rear end, and the semicircular blocks 54 are all located between the two retaining rings 7.

[0035] Specifically, by setting a retaining ring 7, and with the two semicircular blocks 54 located between the retaining ring 7, they will not fall off during shock absorption.

[0036] Example 2

[0037] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 2 , Figure 3 Figure 5 and Figure 6 The mounting assembly 6 includes two sliding blocks 61 that are slidably connected to one side of the bottom of the inner cavity of the seat base 1 and a locking block 62 that is fixedly installed on the opposite side of the sliding blocks 61. The mounting base 4 has slots on both sides, and the locking blocks 62 are movably inserted into the inner cavities of the adjacent slots. A rack plate 63 is fixedly installed on the opposite side of the sliding blocks 61 near the front side. The opposite side of the rack plates 63 is meshed with a rotating gear 65, and a lever 64 is fixedly installed on the front side of one of the sliding blocks 61.

[0038] Specifically, when installing the mounting base 4, with the cooperation of the mounting component 6, the two sliding blocks 61 can be moved to the opposite side, and the locking block 62 fixed on the adjacent sliding block 61 can be movably inserted into the inner cavity of the adjacent locking slot, which facilitates the installation or removal of the mounting base 4.

[0039] A fixing rod 651 is fixedly installed at the bottom center of the rotating gear 65, and the bottom end of the fixing rod 651 is rotatably connected to the bottom of the inner cavity of the seat base 1.

[0040] Specifically, the rotating gear 65 can be supported by setting a fixing rod 651.

[0041] A reset telescopic rod 611 is fixedly installed on both the front and rear sides of the sliding block 61 on the side away from each other. A mounting block 613 is fixedly installed on one end of the reset telescopic rod 611. The bottom of the mounting block 613 is fixedly connected to the bottom of the inner cavity of the seat base 1. A reset spring 612 is movably sleeved on the bottom of the reset telescopic rod 611. The two ends of the reset spring 612 are fixedly connected to the mounting block 613 and the sliding block 61, respectively.

[0042] Specifically, during installation, if the lever 64 is released, the locking block 62 can be inserted into the inner cavity of the adjacent slot under the cooperation of the reset telescopic rod 611 and the reset spring 612, and the locking block 62 can be stably inserted into the inner cavity of the slot, thereby improving the stability of the mounting base 4.

[0043] Working principle: When using this utility model, if the mounting base 4 needs to be installed, first push the lever 64 to one side, which will cause the sliding block 61 fixed on the lever 64 to slide to one side. With the cooperation of the rack plate 63 and the rotating gear 65, the sliding block 61 on the other side can slide. At this time, the operator can insert the positioning block 8 fixed at the bottom of the mounting base 4 into the inner cavity of the slot. Then, release the lever 64. With the cooperation of the reset telescopic rod 611 and the reset spring 612, the locking block 62 can be inserted into the inner cavity of the adjacent slot, which facilitates the installation of the mounting base 4. After installation... After completion, the semicircular block 54 is located between the two retaining rings 7. During the flipping of the pedal 2, if a large pressure suddenly occurs, the damping spring 56 and the damper 55 can initially reduce the shock on the electric cylinder body 3. When the movable plate 52 moves forward, the trapezoidal block 523 can move to the side away from the fixed block 521 and the fixed shaft 522 in cooperation. This can squeeze and compress the telescopic rod 524 and the compression spring 525, further buffering and reducing the shock on the electric cylinder body 3, preventing it from being damaged due to excessive instantaneous force, and extending its service life.
