[0015] The present invention provides a mobile phone mainboard that is automatically isolated when encountering liquid, which has the following beneficial effects: users can replace various functional module boards installed on the mainboard according to their own preferences and usage requirements, and compared with standardized mobile phones, this makes the configuration and upgrade of the mobile phone flexible, and when the mobile phone needs to be upgraded, only the corresponding functional module board needs to be replaced, which can reduce the waste of resources caused by replacing the entire mobile phone, the chip board is encapsulated inside the functional module board, and compared with the traditional chip board directly exposed on the mainboard, the probability of the chip board contacting the external water body can be greatly reduced, and the surfaces of the contact point and the first contact spring are covered with a hydrophobic layer of polyolefin material. During the contact between the contact point and the first contact spring, the hydrophobic layer can wrap and cover the internal battery cells of the two, and when the external water body contacts the contact point and the first contact spring, the hydrophobic layer can automatically isolate the water body, which can effectively avoid the short circuit caused by the contact between the water body and the contact point and the first contact spring.

[0016] 1. The present invention adopts magnetic adsorption connection between the function module board and the module docking assembly, which makes the function module board easily separated from the main board, which can reduce the difficulty of installing the function module board on the surface of the main board. By opening the sealing cover plate at the rear of the mobile phone, the placement groove at the rear of the mobile phone is exposed, and the main board can be taken out from the inside of the mobile phone by pulling out the pull-out seat. This allows users to replace various function module boards installed on the main board according to their own preferences and usage requirements. Compared with standardized mobile phones, this makes the configuration and upgrade of the mobile phone more flexible, and when the mobile phone needs to be upgraded, only the corresponding function module board needs to be replaced, which can reduce the waste of resources caused by replacing the entire mobile phone, and also reduce the cost of users replacing mobile phones.

[0017] 2. The chip board of the present invention is encapsulated inside the functional module board. Compared with the traditional chip board directly exposed on the main board, the probability of the chip board contacting the external water body can be greatly reduced, which can improve the waterproof performance of the entire main board. The surfaces of the contact point and the first contact spring are covered with a hydrophobic layer made of polyolefin material. During the contact between the contact point and the first contact spring, the hydrophobic layer can wrap and cover the internal battery cells of the two. When the external water body contacts the contact point and the first contact spring, the hydrophobic layer can automatically isolate the water body, which can effectively avoid the short circuit caused by the contact between the water body and the contact point and the first contact spring. In addition, the outer ends of the contact point and the first contact spring themselves have a first magnetic attraction layer and a second magnetic attraction layer for suction sealing, which can greatly reduce the probability of the contact point and the first contact spring contacting the water body. In addition, the waterproof rubber layer at the outer end of the pull-out seat can fill the connection gap between the pull-out seat and the mobile phone, which further improves the waterproof performance of the device.

[0018] 3. After the pull-out seat of the present invention is installed, the mobile phone battery is placed inside the placement groove, so that the mobile phone battery can contact the battery contact spring sheet. At the same time, the mobile phone battery can fill the entire placement groove, and its top can fit with the pull-out seat. The mobile phone battery limits the pull-out seat, which can ensure the placement stability of the motherboard inside the mobile phone. In addition, the bottom of the sealing cover plate has a small protrusion that connects with the pull-out seat and the groove on the surface of the mobile phone battery. After the sealing cover plate and the back cover of the mobile phone are connected with the fixing screws, the sealing cover plate can ensure that the pull-out seat and the mobile phone battery always maintain a relative position through the small protrusion on the inner side of the bottom. This allows the mobile phone to achieve the placement stability of the pull-out seat and the motherboard by using its own components without the need for additional limiting parts.

[0019] 4. If the mobile phone of the present invention collides or falls during use, the force generated by the collision or fall can be transmitted to the inner side of the compartment layer through the functional module board. After the compartment layer is vibrated, the telescopic rod can be relatively stretched or contracted. During the stretching or contraction process, the telescopic rod can pull the outer reset spring to deform. By deforming the reset spring, the vibration force can be absorbed, which can effectively prevent the vibration force from being transmitted to the chip board, causing the chip on the chip board to be damaged due to vibration, which is beneficial to improving the protection performance of the mainboard.

[0020] 5. After the mainboard of the present invention is installed, the camera docking assembly at the middle end of the outer side of the mainboard can be moved to the position of the camera slot and overlap with the position of the camera slot. At this time, after the camera module is inserted into the inner side of the camera slot, the camera module can be connected with the camera docking assembly. The camera docking assembly and the inner side of the camera module are also connected with a magnetic layer, and the surface of the docking contact points and contact springs are also covered with a hydrophobic layer, which can ensure that the camera module and the camera docking assembly have good waterproof effect and fixed stability during docking, and the bottom inner circle of the camera module is connected with a rubber layer consistent with the contour of the camera slot, which prevents external water from entering the inside of the device from the camera slot. For photography enthusiasts, the camera module needs to be replaced frequently to achieve different imaging effects. By allowing the camera module to be inserted and replaced after the mainboard is fixed and limited, the convenience of replacing the camera module can be greatly improved, and the needs of photography enthusiasts can also be met.

[0021] 6. The present invention can work through the micro exhaust fan on the inner side of the pull-out seat. Through the operation of the micro exhaust fan, the dust that enters the inside of the mobile phone along with the pull-out seat can be discharged from the mobile phone through the connecting groove, which can prevent the dust from causing a short circuit to the connection of the motherboard. In addition, after water enters the inside of the mobile phone, the water will adhere to the surface of the motherboard due to the hydrophobicity of the hydrophobic layer. Through the exhaust of the micro exhaust fan, the water can be discharged from the mobile phone from the connecting groove due to suction, which can improve the cleaning convenience of the equipment after water enters.

[0031] See also Figure 1-4 , the width of the placement groove 2 is consistent with the width of the pull-out seat 3, and the pull-out seat 3 is fixedly connected to the main board 4, the docking layer 501 is integrated with the main board 4, and the outer surface of the docking layer 501 is in contact with the lower surface of the functional module board 6, the first magnetic attraction layer 502 is adsorbed and connected with the second magnetic attraction layer 8, and the first magnetic attraction layer 502 is consistent with the second magnetic attraction layer 8 in size, the first pair of contacts 503 is electrically connected to the first contact spring 7, and the outer surface of the first pair of contacts 503 is in contact with the inner surface of the hydrophobic layer 504;

[0032] The specific operation is as follows: the size of the groove at the bottom of the functional module board 6 is consistent with the size of the docking layer 501. After the functional module board 6 is placed on the top of the docking layer 501, the two can be closely fitted, and at the same time, the first magnetic attraction layer 502 can be adsorbed with the second magnetic attraction layer 8, which makes the connection between the functional module board 6 and the module docking component 5 tighter, which can effectively prevent the two from falling off during the connection process. During the connection process, the first pair of contact points 503 and the first contact spring 7 can be fitted with each other, which makes the functional module board 6 connect to the main board 4, so that the main board 4 can run the function of the functional module board 6. The docking components 5 are connected by magnetic adsorption, which makes it easy to separate the functional module board 6 from the main board 4, which can reduce the difficulty of installing the functional module board 6 on the surface of the main board 4, and by opening the sealing cover 17 at the rear of the mobile phone 1, the rear placement slot 2 of the mobile phone 1 is exposed, and the main board 4 can be completely taken out from the inside of the mobile phone 1 by pulling out the pull-out seat 3, which allows the user to replace various functional module boards 6 installed on the main board 4 according to their own preferences and usage needs. Compared with the standardized mobile phone 1, this makes the configuration and upgrade of the mobile phone 1 flexible, and when the mobile phone 1 needs to be upgraded, it only needs to replace the corresponding functional module board 6, which can reduce the replacement cost. The resource waste caused by replacing the entire mobile phone 1 can also be reduced, and the user's expenses for replacing the mobile phone 1 can also be reduced. In addition, the chip board 904 is encapsulated inside the functional module board 6, and is only electrically connected to the first contact spring 7 through the docking line 905. Compared with the traditional chip board 904 directly exposed on the main board 4, the probability of the chip board 904 contacting the external water body can be greatly reduced, which can improve the waterproof performance of the entire main board 4. The surfaces of the first pair of contact points 503 and the first contact spring 7 are covered with a hydrophobic layer 504 made of polyolefin. During the contact between the first pair of contact points 503 and the first contact spring 7, the hydrophobic layer 504 can separate the battery cells inside the two. The hydrophobic layer 504 can automatically isolate the water body when the external water body contacts the first pair of contact points 503 and the first contact spring 7, which can effectively avoid the short circuit caused by the contact between the water body and the first pair of contact points 503 and the first contact spring 7. In addition, the outer ends of the first pair of contact points 503 and the first contact spring 7 themselves have the first magnetic attraction layer 502 and the second magnetic attraction layer 8 for suction and sealing, which can greatly reduce the probability of the first pair of contact points 503 and the first contact spring 7 contacting the water body. In addition, the waterproof rubber layer 14 at the outer end of the pull-out seat 3 can fill the connection gap between the pull-out seat 3 and the mobile phone 1, which further improves the waterproof performance of the device.

[0033] See also Figure 4 and Figure 5The chip assembly 9 includes a compartment layer 901, a telescopic rod 902, a return spring 903, a chip board 904 and a docking line 905. The compartment layer 901 is provided with telescopic rods 902 on both sides thereof, and the outer ends of the telescopic rods 902 are connected with return springs 903. The telescopic rods 902 are connected with the chip board 904 on one side close to the vertical center line of the compartment layer 901, and a docking line 905 is provided on the outer side of the bottom of the chip board 904. The compartment layer 901 is integrated with the functional module board 6, and the vertical center line of the compartment layer 901 coincides with the vertical center line of the chip board 904. The telescopic rods 902 and the chip board 904 are vertically distributed, and the telescopic rods 902 are elastically connected with the return spring 903.

[0034] The specific operation is as follows. After the functional module board 6 is installed, the pull-out seat 3 is re-placed back to the inner side of the placement groove 2. By pushing the pull-out seat 3, the main board 4 can enter the inner side of the mobile phone 1, which enables the second contact spring 11 at the outer end of the main board 4 to contact the second pair of contact points 13 on the internal connection function board 12 of the mobile phone 1, so that the main board 4 can be connected to the mobile phone 1. The surface of the second contact spring 11 and the second pair of contact points 13 are also covered with a hydrophobic layer 504 made of polyolefin material, which can effectively avoid a short circuit in the connection between the second contact spring 11 and the second pair of contact points 13. After the pull-out seat 3 is installed, the mobile phone battery 15 is placed on the inner side of the placement groove 2, so that the mobile phone battery 15 can contact the battery contact spring 16. At the same time, the mobile phone battery 15 can fill the entire placement groove 2, and its top can fit with the pull-out seat 3. The mobile phone battery 15 limits the pull-out seat 3, so that the placement stability of the main board 4 inside the mobile phone 1 can be guaranteed. In addition, the bottom of the sealing cover plate 17 has a contact with the pull-out seat 3. A small protrusion that docks with the groove on the surface of the mobile phone battery 15. After the sealing cover plate 17 and the back cover of the mobile phone 1 are connected by fixing screws, the sealing cover plate 17 can ensure that the pull-out seat 3 and the mobile phone battery 15 always maintain a relative position through the small protrusion on the inner side of the bottom, which allows the mobile phone 1 to achieve the placement stability of the pull-out seat 3 and the main board 4 by using its own components without additional limiting parts. If the mobile phone 1 collides or falls during use, the force generated by the collision or fall can be transmitted to the inner side of the compartment layer 901 through the functional module board 6. After the compartment layer 901 is vibrated, the telescopic rod 902 can be relatively stretched or contracted. During the stretching or contraction process, the telescopic rod 902 can pull the outer reset spring 903 to deform. By deforming the reset spring 903, the vibration force can be absorbed, which can effectively prevent the vibration force from being transmitted to the chip board 904, causing the chip on the chip board 904 to be damaged due to vibration, which is beneficial to improving the protection performance of the main board 4.

[0035] See also Figure 1 , Figure 6 and Figure 7, connecting grooves 20 are provided on both sides of the interior of the pull-out seat 3, and the inner side of the connecting grooves 20 is connected to a micro exhaust fan 21, the connecting grooves 20 are symmetrically distributed along the vertical center line of the pull-out seat 3, and the connecting grooves 20 and the micro exhaust fan 21 are fixedly connected by bolts;

[0036] The specific operation is as follows. After the main board 4 is installed, the camera docking assembly 10 at the middle end of the outer side of the main board 4 can be moved to the position of the camera slot 18 and overlap with the position of the camera slot 18. At this time, after the camera module 19 is inserted into the inner side of the camera slot 18, the camera module 19 can be connected with the camera docking assembly 10. The camera docking assembly 10 and the inner side of the camera module 19 are also connected with a magnetic absorption layer, and the surface of the docking contact points and the contact springs are also covered with a hydrophobic layer 504, which can ensure that the camera module 19 has a good waterproof effect and fixed stability during the docking process with the camera docking assembly 10, and the bottom inner ring of the camera module 19 is connected with a rubber layer consistent with the contour of the camera slot 18, which prevents external water from entering the inside of the device from the camera slot 18. For photography enthusiasts, the camera module 19 needs to be replaced frequently. The camera module 19 can be replaced after the mainboard 4 is fixed and limited, which greatly improves the convenience of replacing the camera module 19 and meets the needs of photography enthusiasts. After the pull-out seat 3 and the mobile phone battery 15 are inserted, the micro-exhaust fan 21 on the inside of the pull-out seat 3 can work. Through the operation of the micro-exhaust fan 21, the dust that enters the inside of the mobile phone 1 along with the pull-out seat 3 can be discharged from the mobile phone 1 through the connecting groove 20, which can prevent the dust from causing a short circuit to the connection of the mainboard 4. In addition, after water enters the inside of the mobile phone 1, the water will adhere to the surface of the mainboard 4 due to the hydrophobicity of the hydrophobic layer 504. The water can be discharged from the mobile phone 1 from the connecting groove 20 due to suction through the exhaust of the micro-exhaust fan 21, which can improve the cleaning convenience of the device after water enters.

[0037] In summary, when the mobile phone motherboard that is automatically isolated when encountering liquid is used, the function module board 6 is first placed on the top of the docking layer 501, and the first magnetic layer 502 can be adsorbed with the second magnetic layer 8, so that the function module board 6 and the module docking component 5 can be closely fitted, which can effectively prevent the two from falling off during the connection process. During the connection process, the first pair of contact points 503 and the first contact spring 7 can be mutually fitted, so that the function module board 6 can be connected to the motherboard 4, so that the motherboard 4 can run the function of the function module board 6. Because the function module board 6 and the module docking component 5 are connected by magnetic adsorption, the function module board 6 can be easily separated from the motherboard 4, which can reduce the difficulty of installing the function module board 6 on the surface of the motherboard 4. By opening the sealing cover plate 17 at the rear of the mobile phone 1, the rear placement groove 2 of the mobile phone 1 is exposed, and the mainboard 4 can be completely taken out from the inside of the mobile phone 1 by pulling out the pull-out seat 3, so that the user can replace various function module boards 6 placed on the motherboard 4 according to his own preferences and usage requirements;

[0038] Then, after the functional module board 6 is installed, the pull-out seat 3 is relocated back to the inside of the placement groove 2, and the main board 4 can be pushed into the inside of the mobile phone 1 by pushing the pull-out seat 3, so that the second contact spring 11 at the outer end of the main board 4 can contact the second pair of contact points 13 on the internal connection function board 12 of the mobile phone 1, so that the main board 4 can be connected to the mobile phone 1. After the pull-out seat 3 is inserted, the mobile phone battery 15 is placed inside the placement groove 2, so that the mobile phone battery 15 can contact the battery contact spring 16, and the mobile phone battery 15 can fill the entire placement groove 2, and its top It can fit with the drawer seat 3, and the drawer seat 3 is limited by the mobile phone battery 15, so that the placement stability of the main board 4 inside the mobile phone 1 can be ensured. In addition, the bottom of the sealing cover plate 17 has a small protrusion that docks with the grooves on the surface of the drawer seat 3 and the mobile phone battery 15. After the sealing cover plate 17 and the back cover of the mobile phone 1 are connected by fixing screws, the sealing cover plate 17 can ensure that the drawer seat 3 and the mobile phone battery 15 always maintain a relative position through the small protrusion on the inner side of the bottom, so that the mobile phone 1 can achieve the placement stability of the drawer seat 3 and the main board 4 by using its own components without additional limiting parts;

[0039] Then, if the mobile phone 1 collides or falls during use, the force generated by the collision or falling can be transmitted to the inner side of the compartment layer 901 through the functional module board 6. After the compartment layer 901 is vibrated, the telescopic rod 902 can be relatively stretched or contracted. During the stretching or contraction process, the telescopic rod 902 can pull the outer reset spring 903 to deform. By deforming the reset spring 903, the vibration force can be absorbed, which can effectively prevent the vibration force from being transmitted to the chip board 904, causing the chip on the chip board 904 to be damaged due to vibration, which is conducive to improving the protection performance of the main board 4;

[0040] When the mobile phone is subsequently soaked in water, the chip board 904 is encapsulated inside the functional module board 6, and is only electrically connected to the first contact spring 7 through the docking line 905. Compared with the conventional chip board 904 directly exposed on the main board 4, the probability of the chip board 904 contacting with external water can be greatly reduced, which can improve the waterproof performance of the entire main board 4, and the surfaces of the first pair of contact points 503 and the first contact spring 7 are covered with a hydrophobic layer 504 made of polyolefin. During the contact between the first pair of contact points 503 and the first contact spring 7, the hydrophobic layer 504 can wrap and cover the internal cells of the two. When the external water and During the contact between the first pair of contact points 503 and the first contact spring 7, the hydrophobic layer 504 can automatically isolate the water body, which can effectively avoid the short circuit caused by the contact between the water body and the first pair of contact points 503 and the first contact spring 7. In addition, the outer ends of the first pair of contact points 503 and the first contact spring 7 themselves have the first magnetic attraction layer 502 and the second magnetic attraction layer 8 for attraction and sealing, which can greatly reduce the probability of the first pair of contact points 503 and the first contact spring 7 contacting the water body. In addition, the waterproof rubber layer 14 at the outer end of the pull-out seat 3 can fill the connection gap between the pull-out seat 3 and the mobile phone 1, which further improves the waterproof performance of the device.

[0041] After the pull-out seat 3 and the mobile phone battery 15 are inserted, the micro exhaust fan 21 inside the pull-out seat 3 can work. Through the operation of the micro exhaust fan 21, the dust that enters the inside of the mobile phone 1 along with the pull-out seat 3 can be discharged from the mobile phone 1 through the connecting groove 20, which can prevent the dust from causing a short circuit to the connection of the main board 4. In addition, after water enters the inside of the mobile phone 1, the water will adhere to the surface of the main board 4 due to the hydrophobicity of the hydrophobic layer 504. Through the exhaust of the micro exhaust fan 21, the water can be discharged from the mobile phone 1 from the connecting groove 20 due to suction, which can improve the cleaning convenience of the device after water enters.

[0042] Finally, after the main board 4 is installed, the camera docking assembly 10 at the middle end of the outer side of the main board 4 can be moved to the position of the camera slot 18 and overlap with the position of the camera slot 18. At this time, after the camera module 19 is inserted into the inner side of the camera slot 18, the camera module 19 can be connected to the camera docking assembly 10. The camera docking assembly 10 and the inner side of the camera module 19 are also connected with a magnetic absorption layer, and the surface of the docking contact points and contact springs are also covered with a hydrophobic layer 504, which can ensure that the camera module 19 has a good waterproof effect and fixed stability during the docking process with the camera docking assembly 10, and the bottom inner circle of the camera module 19 is connected with a rubber layer consistent with the contour of the camera slot 18, so that external water will not enter the inside of the device from the camera slot 18. For photography enthusiasts, the camera module 19 needs to be replaced frequently to achieve different imaging effects. By allowing the camera module 19 to be inserted and replaced after the main board 4 is fixed and limited, the convenience of replacing the camera module 19 can be greatly improved, and the needs of photography enthusiasts can also be met.
