Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 6 This utility model provides a technical solution: a structure for easy disassembly and maintenance of a power module, including a base 1, a fixed seat 12, a lifting seat 2, and a storage tray 7. A support column 3 for mounting the lifting seat 2 is fixed at the upper middle part of the base 1. An electric push rod is fixed inside the support column 3. The telescopic end of the electric push rod is fixed inside the lifting seat 2. Slide rails 5 for longitudinal movement of sliders 4 are fixed on both sides of the support column 3. A limit bolt 6 is threaded to the front end of each slider 4. A storage tray 7 is fixed on one side of each slider 4. A storage groove for placing bolts is opened at the upper end of each storage tray 7. A rubber pad 8 is provided inside the storage groove. A magnetic block 9 for magnetically attracting bolts is provided inside each storage tray.

[0030] The upper end of the lifting seat 2 is provided with a groove for the rotating block 10 to move. Both sides of the groove are provided with reserved holes for the installation of the shafts 11 on both sides of the rotating block 10. The upper end of the rotating block 10 is fixedly installed with a fixing seat 12. Both sides of the fixing seat 12 are fixed with clamps 13 for fixing the laptop shell. Both sides of the clamps 13 are fixed with transmission bars 14. Both transmission bars 14 penetrate into the interior of the fixing seat 12.

[0031] A first self-locking motor 15 is fixed inside the mounting base 12. A drive gear 16 is fixedly mounted on the output shaft of the first self-locking motor 15. The outer side of the drive gear 16 meshes with the opposing teeth 17 of the two transmission bars 14. This invention uses movable clamps 13 on both sides of the mounting base 12 to fix the laptop casing placed on top of the mounting base 12, thus facilitating the user to disassemble and repair the laptop's power module after removing the back panel. After the laptop is placed on top of the mounting base 12, turning on the switch of the first self-locking motor 15 causes the output shaft of the first self-locking motor 15 to rotate, causing the teeth 17 on the two transmission bars 14 to engage. At this time, the two clamps 13 close together. The laptop casing is fixed, and the second self-locking motor 26 can be activated as needed. The drive shaft of the second self-locking motor 26 drives the driven gear 28 to rotate, which changes the tilt angle of the laptop fixed in the mounting base 12, thus facilitating repair by technicians. Secondly, this utility model patent uses multiple storage trays 7 to place the bolts used for fixing the laptop power module during disassembly and repair. In order to prevent the bolts from being lost, each storage tray 7 is equipped with a magnetic block 9 for magnetically attracting the bolts. At the same time, in order to facilitate the use of bolts by technicians, an auxiliary lighting strip 29 is set on the upper part of the inner wall of the storage tray. An electric push rod is used to drive the lifting base 2 to move longitudinally.

[0032] The two transmission bars 14 each have a guide groove in the middle for the guide block 19 to pass through, and the guide block 19 is fixedly installed inside the fixed base 12. The two clamping plates 13 are also fixed with a guide rod 20 on one side, and the guide rod 20 is movably connected to the guide cavity inside the wall of the fixed base 12. By setting the guide block 19 in conjunction with the guide groove in the middle of the transmission bar 14, the movement of the two guide bars is guided, ensuring that the clamping plate 13 will not shift position during the movement process. The presence of the guide rod 20 and the guide cavity further improves the stability of the clamping plate 13 during movement.

[0033] The upper ends of the two clamping plates 13 are fixed with lazy brackets 21, and each lazy bracket 21 has a lamp holder 22 fixed on one side of its upper end. Each lamp holder 22 has an LED light strip 23 inside. The contact surfaces between the two clamping plates 13 and the laptop shell are provided with elastic blocks 24, and the sides of the two elastic blocks 24 are integrally formed with T-shaped blocks 25 that are adapted to the slots on the surface of the clamping plates 13. The lazy brackets 21 at the upper end of the clamping plates 13 play a role in adjusting the usage angle of the lamp holders 22. The LED light strips 23 inside the lamp holders 22 can provide an auxiliary lighting environment for the power module disassembly process, ensuring that the maintenance personnel have sufficient vision when disassembling and installing the power module.

[0034] The lifting seat 2 has a second self-locking motor 26 fixed inside its upper end. The output shaft of the second self-locking motor 26 passes through the side of the lifting seat 2 and is fixed to the drive gear 27. The drive gear 27 is meshed with a driven gear 28 on its outer side. The driven gear 28 is fixedly sleeved on the outside of one of the shafts 11. By setting the second self-locking motor 26, drive gear 27 and driven gear 28 to cooperate with each other, the tilt angle of the rotating block 10 is adjusted. This allows the user to adjust the fixed seat 12 to a suitable angle as needed, thus facilitating... When maintenance personnel disassemble and install the laptop power module and adjust the angle, the second self-locking motor 26 will be activated. The output shaft of the second self-locking motor 26 drives the drive gear 27 to rotate, which in turn drives the driven gear 28 to rotate. At this time, the tilt angle of the rotating block 10 changes. After the adjustment is completed, the second self-locking motor 26 will be turned off. The second self-locking motor 26 will use its own self-locking structure to fix its position. The output shaft of the self-locking motor has a self-locking structure, which is existing technology. Therefore, the self-locking principle of the first self-locking motor 15 and the second self-locking motor 26 will not be described in detail.

[0035] The upper end of the storage compartment is fixed with an auxiliary lighting strip 29, which makes it easier for users to access the bolts in the storage compartment.

[0036] The base 1 has an internal equipment chamber and a negative pressure chamber. A negative pressure fan 30 is fixed inside the equipment chamber, with its negative pressure end extending into the negative pressure chamber. A vent plate 31 is installed on the air inlet side of the equipment chamber. A through hole for placing a dust collection cylinder 33 is provided on one side of the upper end of the base 1. The bottom of the dust collection cylinder 33 extends into the negative pressure chamber, and a filter screen 34 is installed on one side of the dust collection cylinder 33. A telescopic tube 35 is inserted into the upper end of the dust collection cylinder 33. An elastic sealing ring 36 is fixed to the outside of the joint between the telescopic tube 35 and the dust collection cylinder 33. An internal threaded cap 18 is fitted onto the outside of the telescopic tube 35. The telescopic tube 35 is threaded to the upper side of the base 1. The top of the telescopic tube 35 is equipped with a negative pressure nozzle 32. Considering that dust may adhere to the power module installation position during the disassembly of the laptop module, the negative pressure nozzle 32, dust collection cylinder 33 and negative pressure fan 30 work together to collect the dust, thereby preventing dust from adhering to the connection position of the power module. When in use, the fan generates negative pressure, and then the negative pressure nozzle 32 uses the negative pressure to suck the dust into the dust collection cylinder 33. The dust will remain inside the dust collection cylinder 33, and the air will enter the negative pressure fan 30 through the filter screen 34 and then be discharged from the vent plate 31.
