[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] An embodiment of this utility model provides a power circuit board protection structure. Please refer to [link / reference]. Figures 1-3 A bracket assembly 2 is installed on the base plate 3, and a circuit board body 6 is installed inside the lower protective assembly 1. An upper protective assembly 4 is also installed on the upper part of the bracket assembly 2. The bracket assembly 2, the lower protective assembly 1 and the upper protective assembly 4 are all installed inside the protective shell 5, and the protective shell 5 is connected to the base plate 3.

[0027] The bracket assembly 2 includes a support frame 21, which is disposed on both sides of the base plate 3. The support frame 21 is also provided with a mounting slot 22, which can be used to position and install the lower protective assembly 1.

[0028] The lower protection component 1 includes a lower protection plate 13, and lower mounting plates 11 are provided on both sides of the lower protection plate 13. The lower mounting plates 11 are connected to the mounting groove and can protect the bottom and sides of the power circuit board.

[0029] First, install the circuit board body 6 on the lower protective plate 13, then insert the lower mounting plate 11 into the mounting slot 22 on the support frame 21, and then fix the lower mounting plate 11 in the mounting slot 22 with screws. The lower protective plate 13 protects the lower part of the circuit board body 6, and the lower mounting plates 11 on both sides can protect the sides of the circuit board body 6.

[0030] Meanwhile, the lower protective plate 13 and the lower mounting plates 11 on both sides are integrally formed, which improves its overall mechanical compressive strength and facilitates overall manufacturing.

[0031] Furthermore, the lower protective plate 13 and the two sets of lower mounting plates 11 have a concave structure, and the circuit board body 6 is installed in the concave structure, which can expand the crumple space when subjected to impact.

[0032] Furthermore, a gap is provided between the lower mounting plate 11 and the support frame 21, and a gap is provided between the lower protective plate 13 and the bottom, so that airflow can flow from the bottom of the lower protective plate 13 and the side of the lower mounting plate 11, ensuring airflow and facilitating the dissipation of heat inside the circuit board body 6.

[0033] Furthermore, multiple sets of side heat dissipation vents 14 are provided on the lower mounting plate 11, and multiple sets of lower heat dissipation vents 12 are provided on the lower protective plate 13. When the circuit board body 6 is in use, the heat of the circuit board body 6 can be dissipated through the side heat dissipation vents 14 and the lower heat dissipation vents 12, thereby improving the heat dissipation efficiency inside the circuit board body 6.

[0034] Please see Figures 4-6 The upper protective component 4 includes an upper protective plate 41 with an inverted U-shaped structure. A first upper mounting plate 42 and a second upper mounting plate are provided on both sides of the upper protective plate 41. The first upper mounting plate 42 and the second upper mounting plate are connected to the support frame 21 to protect the upper part of the power circuit board. A guide rod 43 is also provided at the bottom of the upper mounting plate. The guide rod 43 is movably disposed in a groove 23. The groove 23 is disposed on both sides of the support frame 21 to guide the movement of the upper mounting plate. A return spring 46 is disposed in the groove 23. One end of the return spring 46 is connected to the guide rod 43. The spring force of the return spring 46 can absorb external impact force.

[0035] When an external object impacts the device, the upper protective plate 41 drives the first mounting plate and the second mounting plate 44 to move downwards. The first mounting plate and the second mounting plate 44 drive the guide rod 43 to move within the groove 23. The guide rod 43 moves and compresses the return spring 46. The return spring 46 can absorb the impact force, reducing the damage to the circuit board body 6 caused by external objects. At the same time, the lower protective component 1 is U-shaped, and the upper protective plate 41 is inverted U-shaped. When the upper protective plate 41 is impacted and collapses, the collapse stroke of the upper protective plate 41 is increased, which can prevent the circuit board body 6 from being damaged and reduce the damage rate of the circuit board body 6.

[0036] In one embodiment, an upper heat dissipation vent 45 is also provided on the upper protective plate 41, which greatly improves the heat dissipation efficiency of the circuit board body 6. At the same time, the upper protective plate 41, the first upper mounting plate 42, and the second upper mounting plate are integrally formed, which improves the compressive strength and reduces the manufacturing difficulty.

[0037] Working principle and usage process of this utility model:

[0038] First, install the circuit board body 6 onto the lower protective plate 13. Then, insert the lower mounting plate 11 into the mounting slot 22 on the support frame 21. Next, fix the lower mounting plate 11 into the mounting slot 22 with screws. The lower protective plate 13 protects the lower part of the circuit board body 6, and the lower mounting plates 11 on both sides can protect the sides of the circuit board body 6. Install the upper protective plate 41, and finally connect the protective shell 5. When an external object impacts this device, the upper protective plate 41 drives the first mounting plate and the second mounting plate. 44 moves downwards, and the first mounting plate and the second mounting plate 44 drive the guide rod 43 to move within the groove 23. The guide rod 43 moves and compresses the reset spring 46. The reset spring 46 can absorb the impact force, reducing the damage to the circuit board body 6 caused by external objects. At the same time, the lower protective component 1 is U-shaped, and the upper protective plate 41 is inverted U-shaped. When the upper protective plate 41 is impacted and collapses, the collapse stroke of the upper protective plate 41 is increased, which can prevent the circuit board body 6 from being damaged and reduce the damage rate of the circuit board body 6.
