Description

Technical Field

[0001] The invention relates to the technical field of mobile phone terminal structures, in particular to a high-heat-conductivity detachable mobile phone terminal. Background Art

[0002] At present, with the development of communication technology, mobile phones have become an indispensable device in people's daily life. There are many types of mobile phones, which are mainly used for communication and have multiple intelligent functions. The widespread use of mobile phones has made mobile phones a close-fitting item for modern people. People carry them with them almost all the time. Such frequent use makes people have higher and higher requirements for mobile phones, which is not only reflected in the communication performance of mobile phones, but also in the requirements for appearance design. Therefore, it is necessary to make a new improvement to the existing mobile phones from the inside out.

[0003] The existing mobile phone terminal includes a mobile phone shell, a screen module arranged on the front side of the mobile phone shell, and a battery cover plate arranged on the back side of the mobile phone shell. The mobile phone shell is provided with a circuit board, a battery and a SIM card mounting seat. The SIM card mounting seat is provided with a chip that matches the SIM card. The input interface of the chip is electrically connected to the output head of the battery, and the output interface of the chip is electrically connected to the input interface of the circuit board. A pressing piece is also provided on the top of the SIM card mounting seat. When the user wants to install the SIM card, the pressing piece is first pulled up or horizontally slid a certain distance, and then the conductor on the SIM card is inserted into the chip, and then the pressing piece is reset so that the pressing piece is pressed on the top surface of the SIM card, thereby realizing the installation of the SIM card. However, when the pressing piece is used to fix the SIM card, due to improper operation or excessive force by the user, it is easy to pull the pressing piece off from the SIM card mounting seat. Due to the loosening of the pressing piece, the SIM card falls off from the chip, which cannot meet the normal use of the user, and increases the additional maintenance cost.

[0004] In addition, the existing mobile phone terminals still have the following defects: 1. After the battery in the mobile phone terminal has been working for a long time, or when the user plays games on the mobile phone, a large amount of heat will be generated on the battery. Excessive temperature will not only reduce the service life of the battery, but also burn other parts in the mobile phone terminal. Although the mobile phone terminal is now equipped with a heat dissipation structure, the heat dissipation structure is inside the mobile phone terminal for heat dissipation, and there is a defect of poor heat dissipation effect. 2. The circuit board is installed in the innermost layer of the mobile phone shell. When the circuit board is damaged, the maintenance personnel need to disassemble the multi-layer external structure to remove the circuit board for maintenance, which undoubtedly reduces the maintenance efficiency of the circuit board. 3. The screen module is the most fragile component. When it is damaged and needs to be replaced, the maintenance personnel need to gradually disassemble the components above the screen module from the back of the mobile phone terminal, so that the screen module can be completely exposed and conveniently replaced with a new screen module. Since the maintenance personnel disassemble more parts, this undoubtedly reduces the replacement efficiency of the screen module. Therefore, there is an urgent need for a mobile phone terminal that prevents SIM card from falling off, prolongs battery life, has good heat dissipation effect, improves the maintenance efficiency of the circuit board, and improves the replacement efficiency of the screen module.

[0037] The working process of this embodiment is as follows:

[0038] When the SIM card in the cavity 4 is to be taken out and replaced with another SIM card 6, the battery cover 16 only needs to be slid toward the rear of the mobile phone case 1 to expose the original SIM card 6. At this time, the SIM card 6 can be directly taken out from the cavity 4 by hand, and then another SIM card is fitted into the cavity 4. Finally, the battery cover 16 is slid toward the top of the mobile phone case 1. After the battery cover 16 is in place, the new SIM card 6 is pressed between the bottom surface of the cavity 4 and the battery cover 16. Therefore, in the whole process of installing the SIM card 6, the SIM card is not installed by using a pressing sheet, but the battery cover 16 is used to press down and install the SIM card. Therefore, compared with the traditional pressing sheet installation method, it effectively avoids the user from damaging the pressing sheet due to misoperation or excessive force, ensures that the conductor on the SIM card is closely matched with the chip 5, and effectively prevents the SIM card from falling off.

[0039] When the mobile phone terminal is used for a long time to play mobile games or to use the mobile phone terminal for a long time, a large amount of heat is generated on the battery 13, and the generated heat is first transferred to the heat conduction box 11, and then the heat conduction box 11 transfers the heat to the heat dissipation teeth 12, and the heat dissipation teeth 12 discharge the generated heat into the air, so the battery 13 is cooled down all the time, effectively avoiding damage due to excessive temperature of the battery 13, thereby extending the service life of the battery, and further extending the service life of the mobile phone terminal. In addition, since the heat dissipation component always conducts the outside world with the battery 13, compared with the traditional heat dissipation structure that dissipates heat in the mobile phone terminal, the heat dissipation effect is significantly improved, so it has the characteristics of good heat dissipation effect.

[0040] When the circuit board 2 is damaged, the maintenance personnel only need to remove the battery cover 16 first, and then unscrew the countersunk screw II27, and then take out the support plate 9 from the mobile phone case 1, and then unscrew all the countersunk screws I25, so that the damaged circuit board 2 is completely exposed. At this time, it is convenient for the maintenance personnel to repair or replace the damaged circuit board 2. Compared with the maintenance personnel performing maintenance in traditional mobile phone terminals, there is no need to disassemble the multi-layer structure other than the circuit board 2, but only need to disassemble the battery cover 16 and the support plate 9 for maintenance, thereby greatly improving the maintenance efficiency of the circuit board.

[0041] When the screen module 19 is damaged, the maintenance personnel only need to operate on the front side of the mobile phone case 1 to remove the damaged screen module 19 from the annular cavity 18 of the annular wrapping strip 17, and then embed the new screen module 19 into the annular cavity 18, thereby realizing the rapid replacement of the screen module 19. Compared with the traditional replacement method, the maintenance personnel do not need to gradually remove the battery cover, circuit board and other parts from the back of the mobile phone terminal to replace the damaged screen module, which greatly facilitates the convenience of the maintenance personnel and improves the maintenance efficiency of the screen module.
