Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessory technology, and in particular to a mobile phone motherboard cover assembly with a long service life. 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] However, the existing technology still has shortcomings. In the existing technology, the motherboard cover of mobile phones is usually fixed by multiple fastening screws. The fastening screws are small in size. When the motherboard needs to be repaired, the disassembly and assembly of the motherboard cover is not only inconvenient, but also if the fastening screws are accidentally lost during the repair, the motherboard cover will not be firmly fixed, thereby reducing the service life of the cover.

[0004] Therefore, we propose a long-life mobile phone motherboard cover assembly to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to provide a mobile phone motherboard cover assembly with a long service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A long-life mobile phone motherboard cover assembly includes a motherboard body; an inner ring is fixedly connected to the upper surface of the motherboard body; a limiting block is fixedly connected to the outer side of the upper surface of the motherboard body; a retainer is fixedly connected to the outer surface of the motherboard body; and a cover is fixedly connected to the upper surface of the motherboard body.

[0008] Preferably, the cover includes an upper cover body fixed to the upper surface of the motherboard; a sealing ring is fixed to the lower surface of the upper cover body; a heat sink is fixed to the upper surface of the upper cover body; a limit plate is fixed to the outer surface of the upper cover body; and a fixing block is fixed to the outer surface of the upper cover body.

[0009] Preferably, the fixture includes an outer frame fixed to the upper surface of the motherboard body; a first sliding groove is provided on the lower surface of the outer frame; an inner frame is slidably installed on the inner surface of the first sliding groove; a fixing groove is provided on the lower surface of the inner frame; a screw is rotatably installed on one outer surface of the inner frame; and a spring is sleeved on the outer circular surface of the screw.

[0010] Preferably, one end of the spring is fixed to one side of the outer surface of the inner frame; the other end of the spring is fixed to the inner surface of the outer frame.

[0011] Preferably, the fixing groove and the fixing block cooperate with each other; the outer circular surface of the screw is rotatably mounted on the inner surface of the outer frame.

[0012] Preferably, the limiting plate is slidably mounted on the outer surface of the limiting block; the upper cover body is located on the outer surface of the inner ring.

[0013] In this utility model, a long-life mobile phone motherboard top cover assembly is provided. Through the arrangement of a limiting block, a top cover body, a fixing block, a limiting plate, an outer frame, a first sliding groove, an inner frame, a screw, a spring, and a fixing groove, when installing the top cover body, the upper cover body is placed on the upper surface of the motherboard body through the cooperation between the limiting plate and the limiting block. Then, the screw is rotated, and the rotation of the screw will drive the screw itself to move. The movement of the screw will drive the inner frame to move, so that the inner frame moves above the fixing block and fixes the fixing block, thereby fixing the top cover body. This achieves rapid installation of the top cover body and improves efficiency.

[0014] In this utility model, a mobile phone motherboard top cover assembly with a long service life is provided. The heat sink improves the heat dissipation efficiency of the top cover body and increases its service life. The sealing ring improves the sealing performance of the top cover body.

[0015] This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A long-life mobile phone motherboard cover assembly includes a motherboard body 1; an inner ring 5 is fixedly connected to the upper surface of the motherboard body 1; a limiting block 2 is fixedly connected to the outer side of the upper surface of the motherboard body 1; a retainer 4 is fixedly connected to the outer surface of the motherboard body 1; and a cover 3 is fixedly connected to the upper surface of the motherboard body 1.

[0023] Furthermore, the cover 3 includes an upper cover body 31 fixed to the upper surface of the motherboard; a sealing ring 33 is fixed to the lower surface of the upper cover body 31; a heat sink 32 is fixed to the upper surface of the upper cover body 31; a limit plate 35 is fixed to the outer surface of the upper cover body 31; and a fixing block 34 is fixed to the outer surface of the upper cover body 31.
