[0032] See also Figure 1-3 A protective device for a self-powered intelligent microcomputer includes a protective shell, the protective shell includes a base 1, a top cover 2, and four side panels 3 arranged between the base 1 and the top cover 2, the four side panels enclose a rectangular chamber, the base 1 and the top cover 2 both include a connecting plate, and the four sides of the connecting plate are provided with folded edges 4, wherein the folded edges of the base 1 extend upward, and the folded edges of the top cover 2 extend downward, and the folded edges are detachably connected to the side panels 3 by connecting bolts 5.

[0033] The electronic components are placed in the rectangular chamber, and the connecting plates and the folded edges enclose an inner cavity that matches the outer contour of the rectangular chamber. During assembly, the side panels 3 are first assembled into a rectangle, and then placed in the inner cavity of the base 1. After placement, the side panels 3 fit the folded edges of the base 1, and then the top cover 2 is placed on the top of the side panels 3, and the connection between the side panels 3 and the base 1, and the connection between the side panels and the top cover 2 are achieved through connecting bolts.

[0034] Two opposite side panels 3 are provided with steps 6 on both sides for connecting with the other two side panels 3 .

[0035] The steps, the folded edges and the other two side panels 3 are provided with corresponding connecting holes for connecting bolts to pass through. This arrangement only requires one connecting bolt to achieve the simultaneous connection between the base 1 (or the top cover 2) and the two adjacent side panels 3, which greatly reduces the use of connecting bolts, reduces the workload of the assembly and disassembly process, and improves convenience. In actual use, only one or more connecting bolts need to be set at the four right angles.

[0036] The bottom of the side plate 3 is provided with an inserting block, and the four sides of the base 1 are respectively provided with slots 7 corresponding to the four side plates 3 and matching with the inserting block.

[0038] The base is provided with a limiting groove 8, and the top cover 2 is provided with a limiting rod 9 corresponding to the limiting groove.

[0039] Similarly, the limiting groove and the limiting rod facilitate limiting the top cover 2 during the assembly process, further improving the convenience of assembly.

[0040] The side plate 3 is provided with heat dissipation holes and wire passing holes.

[0041] The heat dissipation holes are used to dissipate heat to prevent the internal electronic components from overheating and affecting their normal operation. The wire holes are used to pass the connecting wires to facilitate connection with external devices.

[0042] Example 2

[0043] See also Figure 4-6 The difference between this embodiment and embodiment 1 is that: the top cover is provided with an internal locking assembly, and the internal locking assembly includes a threaded rod 10 and two sliders 11. The threaded rod 10 is rotatably connected to the top cover, and the threaded rod 10 is symmetrically provided with two opposite sections of external threads. The sliders 11 are slidably arranged on the top cover, and the two sliders 11 are respectively provided with internal threaded holes matching the two sections of external threads. A connecting rod 12 is hinged on both sides of each slider 11, and an internal locking right-angle block 13 is hinged at the end of the connecting rod 12 away from the slider 11.

[0044] The inner locking assembly is used to lock the four side panels internally to further enhance the stability of the connection. The working principle is: the threaded rod 10 is rotated to make the slider 11 move axially along the threaded rod 10, and the two sliders 11 drive the four inner locking right-angle blocks 13 to move to the four corners of the rectangular chamber respectively through the connecting rod 12, until the four inner locking right-angle blocks 13 are respectively fitted with the four corners, and cooperate with the folded edge of the top cover to achieve the inner locking fixation of the side panels.

[0045] During the movement of the slider 11, since the connecting rod 12 and the slider 11, and the inner locking right-angle block 13 and the connecting rod 12 are all hinged, when the inner locking right-angle block 13 is in the process of just contacting with the side panel to achieving internal locking, it can achieve self-adaptive adjustment so that it fits the right angle formed between the side panel.

[0046] In this embodiment, the inner locking right-angle block includes an arc-shaped moving plate and an L-shaped fixing block connected to the moving plate.

[0047] The slide block is slidably matched with the top cover and can provide guidance for its movement.

[0048] The threaded rod 10 is connected with a bevel gear 14, and the top cover is rotatably connected with a rotating shaft 15, and the rotating shaft is connected with a bevel gear 2 meshing with the bevel gear 1.

[0049] In this embodiment, the rotating shaft passes through the connecting plate of the top cover and extends to the outside, so as to facilitate the rotating operation of the threaded rod 10 .

[0050] The shaft is provided with a sleeve 16 fixed on the top cover, and the sleeve 16 is threadedly connected with a positioning screw 17 for positioning the shaft.

[0051] In this embodiment, the sleeve 16 is fixed to the top of the top cover, and a threaded hole perpendicular to the rotating shaft is opened on the side of the sleeve 16, and a positioning screw is located in the threaded hole.

[0052] By tightening the positioning screw, the shaft can be positioned to prevent it from rotating, thereby ensuring the stability of the locking state inside the inner locking assembly.

[0053] In actual use, the shaft can be a damping shaft. When there is no external force, the shaft does not rotate. When there is an external force and the force reaches a certain value, the shaft rotates. Other positioning structures in the prior art can also be used to position the shaft.

[0054] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
