Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessory technology, specifically to a mobile phone motherboard cover assembly for auxiliary heat dissipation. Background Technology

[0002] The motherboard is one of the main components of a mobile phone. Due to its intricate structure, it is very easy to be damaged. Therefore, a motherboard cover is usually installed after the motherboard is installed to provide some protection.

[0003] Currently, existing mobile phone motherboard covers are usually fixed with multiple fastening screws. These screws are relatively small, and when the mobile phone motherboard needs to be repaired, the disassembly and reassembly of the motherboard cover is not only inconvenient, but also prone to failure if the fastening screws are accidentally lost during repair, resulting in the motherboard cover not being securely fixed and thus lacking practicality. Utility Model Content

[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] Example 1

[0027] See Figure 1-4 A mobile phone motherboard top cover assembly for auxiliary heat dissipation includes a main body assembly 1; the main body assembly 1 includes a mounting base 11, on which a motherboard body 12 is disposed; a top cover body 13 is disposed on the mounting base 11; heat dissipation fins 14 are fixedly connected to the top of the top cover body 13, and multiple fins are disposed thereon; a disassembly assembly 2 is symmetrically disposed on the mounting base 11, the disassembly assembly 2 includes: a plate 21, fixedly connected to the top of the mounting base 11; a placement groove 22, formed on the top of the plate 21; a limiting plate 23, slidably connected to the inside of the plate 21; multiple springs 24 are disposed on the limiting plate 23; a moving plate 25 is fixedly connected to the front surface of the limiting plate 23; a mounting plate 26 is fixedly connected to the outer wall of the top cover body 13; a damper 5 is disposed on the limiting plate 23, and the two ends of the damper 5 are respectively fixedly connected to the outer wall of the limiting plate 23 and the inside of the plate 21; one side of the limiting plate 23 is set as an inclined surface.

[0028] When ready for use, the operator installs the mounting base 11 in the designated position. The mainboard body 12 is protected by the upper cover body 13, and the heat dissipation fins 14 dissipate heat from the upper cover body 13, thereby indirectly dissipating heat from the mainboard body 12. When it is necessary to disassemble the upper cover body 13, the operator pulls the movable plates 25 on the two side plates 21, causing the two side movable plates 25 to move the two side limiting plates 23 simultaneously. When the two side limiting plates 23 move, they compress multiple springs 24, thereby causing the two side limiting plates 23 to completely move out of the top of the mounting plate 26, canceling the limiting fixation of the mounting plate 26 in the two side placement slots 22, thus allowing the upper cover body 13 to be removed. The operation is simple and improves the practicality of the device. When the device is subjected to When the vibration causes the limiting plate 23 to vibrate simultaneously under the action of the spring 24, the damper 5 reciprocates with the vibration structure through the damping rod, driving the piston to move in the cylinder filled with hydraulic oil. The small holes or gaps on the piston force the hydraulic oil to pass through, generating viscous resistance and internal friction between fluid molecules, converting the vibration kinetic energy into heat energy for dissipation, thereby ensuring the stability of the limiting plate 23 in limiting the mounting plate 26. When the operator installs the upper cover body 13, the upper cover body 13 drives the mounting plates 26 on both sides to move simultaneously, so that the mounting plates 26 on both sides press the inclined surfaces on the limiting plates 23 on both sides respectively, so that the limiting plates 23 on both sides automatically move into the plate body 21 without the operator having to pull the moving plate 25 first, thereby improving the convenience of device installation.

[0029] Example 2

[0030] See Figure 1-4 Based on the first embodiment, a linkage function has been added;

[0031] The mounting base 11 is provided with a linkage component 3, which includes: a housing 31, fixedly connected to the top of the mounting base 11, with both movable plates 25 inserted into the housing 31; a linkage plate 32, inserted into the front surface of the housing 31 and slidably connected to the housing 31; a connecting rod 33, with each of the two movable plates 25 hinged to the opposite side, and both connecting rods 33 hinged to the top of the linkage plate 32; a guide rail cover 4 is provided on each movable plate 25 and the linkage plate 32; and springs 6 are symmetrically arranged inside the plate 21.

[0032] During disassembly, the operator pulls the linkage plate 32 on the housing 31 upwards, causing the linkage plate 32 to move the connecting rods 33 on both sides simultaneously. As the connecting rods 33 rotate, they move the moving plates 25 on both sides away from each other, thereby moving the limiting plates 23 on both sides through the moving plates 25. This eliminates the need for the operator to pull the moving plates 25 separately, improving the convenience of the device. When the moving plates 25 and the linkage plate 32 move, they cause the guide rail cover 4 on them to fold or unfold simultaneously. This prevents dust and other debris from entering the plate 21 or housing 31 through the slide groove, thus preventing blockage and improving the stability of the device. When the mounting plate 26 is fully placed in the placement slot 22, the mounting plate 26 compresses the two springs 6 on the same side. When the device releases the limiting effect on the mounting plate 26, the springs 6 on both sides can spring up the mounting plates 26, thereby springing up the top cover body 13, facilitating the disassembly of the top cover body 13 and further improving the disassembly efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
