[0008] As a further description of the above technical solution: the end of the left oblique spring damper away from the sliding column is fixedly connected to the inner wall of one side of the annular groove, and the end of the right oblique spring damper away from the sliding column is fixedly connected to the inner wall of one side of the annular groove.
[0009] As a further description of the above technical solution: the transmission lines are respectively plugged into the transmission port and the right outer wall of the lighting component.
[0010] As a further description of the above technical solution: the end of the vertical spring damper away from the column is fixedly connected to the bottom inner wall of the sliding column.
[0011] As a further description of the above technical solution: the length and width of the power mounting bracket are smaller than the inner diameter of the power housing, and an insulating sleeve is fixedly connected to the outer side wall of the transmission line.

[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, by setting up a left-sloping spring damper, column, sliding column and other structures, the power supply shell is subjected to multiple shocks from impacts from different surfaces. This improves the problem that when the power supply protection board shell falls to the ground, the shell is subjected to multiple impacts from different surfaces, which can easily cause multiple violent vibrations to the internal mobile power supply, thus causing internal damage and failure.
[0018] 2. In this utility model, by setting up structures such as movable plates, arc plates, and compression springs, the power protection board and the housing can be easily disassembled and separated, which facilitates personnel to quickly maintain the internal components. This improves the problem that traditional power housings require disassembly tools to remove the fixing screws during disassembly and repair, which makes the operation cumbersome, time-consuming and labor-intensive.

A buffer mechanism 5 and an auxiliary mechanism 6 are provided on the power protection panel body 3. The buffer mechanism 5 includes an annular groove 51, which is formed on the bottom inner wall of the power protection panel body 3. A sliding post 52 is slidably connected to the bottom inner wall of the annular groove 51, and a fixed connection is made to the left outer wall of the sliding post 52. A left-angled spring damper 53 is used to buffer and reduce vibration on the left side. A column 54 is slidably connected to the top inner wall of the sliding column 52. A right-angled spring damper 55 is fixedly connected to the right outer wall of the sliding column 52 to buffer and reduce vibration on the right side. A vertical spring damper 56 is fixedly connected to the bottom outer wall of the sliding column 52. A power supply mounting bracket 57 is fixedly connected to the top outer wall of the column 54. A transmission line 58 is inserted into the left outer wall of the power supply mounting bracket 57.
[0027] Reference Figure 2 - Figure 4 The left oblique spring damper 53 is fixedly connected to the inner wall of one side of the annular groove 51 at one end away from the sliding column 52. The right oblique spring damper 55 is fixedly connected to the inner wall of one side of the annular groove 51 at one end away from the sliding column 52. The transmission line 58 is respectively inserted into the transmission port 2 and the outer wall of the right side of the lighting component 4. The vertical spring damper 56 is fixedly connected to the inner wall of the bottom of the sliding column 52 at one end away from the column 54. The vertical spring damper 56 is used to buffer and reduce the vertical force on the column 54. The length and width of the power mounting bracket 57 are smaller than the inner diameter of the power housing 1. An insulating sleeve is fixedly connected to the outer wall of the side of the transmission line 58. The insulating sleeve is used to prevent leakage of current on the outer surface of the transmission line 58. The transmission port 2 is opened on the inner wall of the left side of the power housing 1. The power protection plate body 3 is slidably connected to the inner walls of the left and right sides of the power housing 1. The lighting component 4 is fixedly connected to the outer wall of the left side of the power housing 1.
[0028] Reference Figure 3 - Figure 4The auxiliary mechanism 6 includes a movable plate 61, which is slidably connected to the right outer wall of the power protection board body 3. An arc-shaped plate 62 is fixedly connected to the top outer wall of the movable plate 61. A groove 63 is provided on the right outer wall of the power protection board body 3. A handle 64 is hinged to the right outer wall of the movable plate 61. A compression spring 65 is fixedly connected to the bottom outer wall of the movable plate 61. The compression spring 65 generates a continuous pushing force on the movable plate 61. The arc-shaped plate 62 penetrates the top outer wall of the power protection board body 3 and is snapped into the top inner wall of the power housing 1. The outer diameter of the handle 64 is adapted to the inner diameter of the groove 63. A frosted pad is fixedly connected to the side outer wall of the handle 64. The end of the compression spring 65 away from the movable plate 61 is fixedly connected to the right inner wall of the power protection board body 3.
[0029] Working principle: When the power supply housing 1 falls to the ground, it will collide with multiple sides. When the left side of the power supply housing 1 is impacted, the impact is transmitted to the left inclined spring damper 53 for left-side buffering and shock absorption, reducing the vibration of the sliding column 52 on the left side. At the same time, when the right side of the power supply housing 1 is impacted, the impact is transmitted to the right inclined spring damper 55 for right-side buffering and shock absorption, reducing the violent vibration of the sliding column 52 on the right side. When the power supply housing 1 falls to the ground from both sides, the column 54 shakes up and down, squeezing the vertical spring damper 56 for buffering and shock absorption, reducing the violent vibration of the equipment on the power supply mounting bracket 57 from multiple sides. At the same time, when internal maintenance and replacement are required, the pull handle 64 is pulled out from the groove 63, and then the pull handle 64 is pulled down to move the movable plate 61. The movement of the movable plate 61 drives the arc plate 62 to move, and the arc plate 62 moves and separates from the power supply housing 1. Then, the pull handle 64 is pulled out from the bottom of the power supply housing 1, and then the transmission line 58 is disconnected, making it convenient for personnel to maintain and inspect the internal components.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
