Description

Technical Field

[0001] The present invention relates to the technical field, and more particularly to a power adapter capable of conveniently installing a heat dissipation module. Background Art

[0002] With the rapid development of modern electronic devices, the performance and power requirements of computers are constantly increasing. Traditional power adapter designs face severe heat dissipation challenges. As the power consumption of core components such as processors and graphics cards continues to increase, the output power of power adapters also increases accordingly. Traditional passive heat dissipation methods alone can no longer meet the heat dissipation needs. Although active heat dissipation is an effective solution to this problem, the traditional integrated radiator design will significantly increase the size of the power adapter, which not only affects the portability of the device, but also increases production and transportation costs. Especially in office environments with limited space, large-volume power adapters often cause waste of desktop space and inconvenience in use.

[0003] In addition, the design of existing power adapters has obvious deficiencies in modular installation and daily maintenance. The installation mechanism of most cooling modules is complicated, which not only increases the difficulty of installation, but also easily leads to the problem of reduced cooling effect due to improper installation. At the same time, in scenarios where active cooling is not required, the dust-proof design of the cooling holes is generally missing or ineffective, which makes it easy for dust to enter the device through the cooling holes. This design defect will not only reduce the cooling efficiency, but also accelerate the aging of the equipment and shorten its service life. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the problems existing in the prior art, the present invention provides a power adapter on which a heat dissipation module can be conveniently installed to solve the technical problems mentioned in the background technology.

Each expansion block is provided with a lateral groove, and the lateral bar is slidably connected in the lateral groove. A friction block is installed on each lateral bar, and the multiple friction blocks respectively abut against the inner wall of the fixing hole. A spring is installed on the lower end surface of the self-locking sleeve, and the spring abuts against the fixing hole. There are multiple fans, and the multiple fans are installed on the air inlet shell respectively. The unlocking mechanism is installed on the self-locking sleeve, and the sealing mechanism is installed on the power supply body.

[0006] Preferably, a self-locking spring is provided at the lower end of each friction block, and the multiple self-locking springs respectively abut against the lower end surface of the self-locking sleeve. This arrangement allows the self-locking spring to continuously support and abut against the self-locking sleeve as the friction block moves, thereby enhancing the locking effect between the self-locking sleeve and the lateral strip and ensuring effective fixation of the friction block and the fixing hole.

[0007] Preferably, the unlocking mechanism includes a synchronous disk, a follower block and a support spring, the synchronous disk and the self-locking sleeve are coaxially arranged, a follower block is respectively installed on each of the lateral strips, the synchronous disk is attached to the plurality of follower blocks, a support spring is installed on the lower end surface of the synchronous disk, and the support spring abuts against the lower end surface of the self-locking sleeve. This arrangement enables the synchronous disk to drive the lateral strips to move, thereby ensuring the connection between the friction block and the fixed hole, thereby ensuring the convenience of unlocking.

[0008] Preferably, an unlocking rod is slidably provided on each of the self-locking sleeves, the unlocking rod is connected to the synchronization disk, and the unlocking rod and the self-locking sleeve are coaxially arranged, and a pull rod is provided on every two of the unlocking rods. This arrangement allows the user to synchronously drive multiple unlocking rods for quick unlocking and disassembly by simply pulling the pull rod, thereby effectively improving the disassembly efficiency.

[0009] Preferably, a rubber strip is provided on the inner wall of the air inlet shell, and a sealing groove is opened on the side wall of the power supply body, and the rubber strip is inserted into the sealing groove. This arrangement can form an effective seal between the air inlet shell and the power supply body, effectively isolating the entry of external dust and foreign matter, and ensuring a clean operating environment for the internal components of the power supply.

[0010] Preferably, two power supply rods are provided on the air inlet shell, and the multiple fans are electrically connected to the two power supply rods respectively, and a power supply port is opened on the side wall of the power supply body, and the power supply rod is inserted into the power supply port, and the two power supply rods are electrically connected to the power supply body respectively.

[0012] Preferably, a contraction groove is provided on the inner wall of the two-way sleeve, a plurality of expansion springs are provided in the contraction groove, a top ball is provided on each of the expansion springs, an annular groove is provided on the inner wall of the mounting hole, and the plurality of top balls respectively abut against the annular groove.

At the same time, during disassembly, the two-way sleeve only needs to be pulled outward to overcome the resistance of the expansion spring and quickly separate the components.

[0013] Preferably, a return spring is provided at both ends of each guide block, and a stop disk is provided at both ends of each guide groove. The two return springs respectively abut against the stop disks at both ends. This arrangement enables the guide block to achieve reliable guiding under the limit of the stop disk during the back-and-forth sliding of the bidirectional sleeve.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a power adapter that can conveniently install a heat dissipation module, which has the following beneficial effects: The installation mechanism realizes the rapid installation of the cooling module of the power adapter through the cooperation connection of the self-locking sleeve and the fixing hole. The close fit between the air inlet shell and the power body not only ensures good sealing, but also improves the heat dissipation effect. The coordinated design of the lateral strips and the friction block ensures the stability of the entire installation process. The cooperation of the spring provides appropriate thrust, so that the friction block can continue to firmly contact the inner wall of the fixing hole. This self-locking design not only simplifies the installation steps, but also ensures the reliable fixation of the cooling module, significantly improving the maintainability of the entire power adapter. The design of the entire installation mechanism not only realizes a quick and convenient installation process, but also effectively solves the problems of complex installation and poor stability of traditional radiators.

[0016] The unlocking mechanism realizes the rapid disassembly of the heat dissipation module through the coordinated cooperation of the synchronization disk and the follower block. The design of the unlocking rod and the pull rod simplifies the operation process. The unlocking can be completed with a light pull. This convenient unlocking mechanism not only improves the user experience, but also reduces the difficulty of operation when maintaining the power adapter. At the same time, the unlocking process will not affect the installation status of the heat dissipation module, ensuring the stability of the device. The design of the entire unlocking mechanism not only achieves the goal of rapid disassembly, but also fully considers the user's convenience.

[0017] The sealing mechanism ensures that the power adapter is dust-proof even when it is not in active heat dissipation through the precise cooperation of the two-way sleeve, the middle disk and the guide block. The synchronous movement of the top rod drives the middle disk to slide in the guide groove, realizing dynamic coordination with the air inlet shell. The opening and closing design of the connecting groove cleverly controls the airflow channel, ensuring that a good sealing effect can be maintained regardless of whether there is a heat dissipation demand. The cooperation of the expansion spring and the return spring ensures the stable position of the middle disk and avoids leakage. This adaptive sealing mechanism not only isolates dust from entering, but also ensures the convenient installation of active heat dissipation, greatly improving the service life of the power adapter. The design of the entire sealing mechanism balances the needs of dust prevention and heat dissipation, bringing users an excellent user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1 to 4 and Figure 8 to Figure 9A power adapter that can conveniently install a heat dissipation module includes a power supply body 1, a mounting mechanism is arranged on the power supply body 1, the mounting mechanism includes an air inlet shell 2, a self-locking sleeve 3, a lateral strip 4, an expansion block 5, a friction block 6, a spring 7, a fan 8, an unlocking mechanism and a sealing mechanism, the air inlet shell 2 is attached to the side wall of the power supply body 1, a plurality of self-locking sleeves 3 are installed in the air inlet shell 2, and a plurality of fixing holes 9 are opened on the side wall of the power supply body 1, the fixing holes 9 and the self-locking sleeve 3 are coaxially arranged, a plurality of expansion blocks 5 are arranged, and the plurality of expansion blocks 5 are respectively installed on the side wall of the self-locking sleeve 3 at equal intervals. A lateral groove 10 is provided in each expansion block 5, and the lateral strip 4 is slidably connected in the lateral groove 10. A friction block 6 is installed on each lateral strip 4, and multiple friction blocks 6 respectively abut against the inner wall of the fixing hole 9. A spring 7 is installed on the lower end surface of the self-locking sleeve 3, and the spring 7 abuts against the fixing hole 9. A plurality of fans 8 are provided, and the multiple fans 8 are respectively installed on the air inlet shell 2. The unlocking mechanism is installed on the self-locking sleeve 3, and the sealing mechanism is installed on the power supply body 1. A self-locking spring 11 is provided at the lower end of each friction block 6, and multiple self-locking springs 11 respectively abut against the lower end surface of the self-locking sleeve 3.

[0024] Working principle: When the power supply needs to actively dissipate heat, the air inlet shell 2 is first installed on the power supply body 1. Since the self-locking sleeve 3 is installed on the air inlet shell 2, the self-locking sleeve 3 needs to be inserted into multiple fixing holes 9 respectively. As the self-locking sleeve 3 goes deeper into the fixing hole 9, the rubber strip 17 is also inserted into the sealing groove 18. Since the rubber strip 17 is ductile, it will deform under continuous pressure so that the self-locking sleeve 3 continues to be inserted into the fixing hole 9, and the spring 7 is also in a continuous compression state. When compressed to the maximum force, the side walls of the multiple friction blocks 6 are respectively attached to the inner wall of the fixing hole 9, and under the action of the self-locking spring 11, the lateral strip 4 will slide along the lateral groove 10, through The expansion force is obtained by sliding downward, so multiple friction blocks 6 will be tightly attached to the inner wall of the fixing hole 9, and then the operator releases the pressure, and the self-locking sleeve 3 has an upward reverse thrust under the action of the spring 7. At this time, the friction block 6 has been attached to the inner wall of the fixing hole 9, so the friction block 6 and the fixing hole 9 are in a relatively static state. With the elastic force applied by the spring 7, the lateral strip 4 will have a tendency to continue to expand along the lateral groove 10, so it will continue to form self-locking, thereby ensuring the fixed state. At this time, the rubber strip 17 and the sealing groove 18 are also in an extruded state, so the air inlet shell 2 is fixed on the side wall of the power supply body 1, and the sealing state of the air inlet shell 2 and the power supply body 1 is guaranteed.

[0025] In simple terms, the air inlet housing 2 only needs to be pressed against the side wall of the power supply body 1 and then released to complete the fixation.

[0026] In order to facilitate the disassembly of the heat dissipation module, an unlocking mechanism is added. Please refer to Figure 2 to Figure 3 and Figure 8 to Figure 9The unlocking mechanism includes a synchronous disk 12, a follower block 13 and a support spring 14. The synchronous disk 12 and the self-locking sleeve 3 are coaxially arranged. A follower block 13 is installed on each lateral bar 4. The synchronous disk 12 is attached to multiple follower blocks 13. A support spring 14 is installed on the lower end surface of the synchronous disk 12. The support spring 14 abuts against the lower end surface of the self-locking sleeve 3. An unlocking rod 15 is slidably provided on each self-locking sleeve 3. The unlocking rod 15 is connected to the synchronous disk 12, and the unlocking rod 15 and the self-locking sleeve 3 are coaxially arranged. An axial arrangement is provided, a pull rod 16 is provided on every two unfastening rods 15, a rubber strip 17 is provided on the inner wall of the air inlet shell 2, a sealing groove 18 is provided on the side wall of the power supply body 1, and the rubber strip 17 is inserted into the sealing groove 18, two power supply rods 19 are provided on the air inlet shell 2, and multiple fans 8 are electrically connected to the two power supply rods 19 respectively, and a power supply port 20 is provided on the side wall of the power supply body 1, and the power supply rod 19 is inserted into the power supply port 20, and the two power supply rods 19 are electrically connected to the power supply body 1 respectively.

[0027] Working principle: When it is necessary to release the fixation of the air inlet shell 2, the operator's index finger and thumb are respectively inserted between the pull rod 16 and the air inlet shell 2, and then continuous force will drive multiple release rods 15 to pull upward at the same time, and the synchronous disk 12 will move accordingly. Since the synchronous disk 12 abuts against multiple follower blocks 13, it will drive multiple lateral strips 4 to slide upward. At this time, the lateral strips 4 will slide upward while shrinking, and then the fixation between the friction block 6 and the fixing hole 9 will be released, thereby releasing the seal between the air inlet shell 2 and the power supply body 1.

[0028] Simply put, you only need to insert your index finger and thumb between the pull rod 16 and the air inlet housing 2 respectively, and then pull upward to release the connection between the air inlet housing 2 and the power supply body 1.

[0029] See also Figures 1 to 7In order to realize the sealing and unlocking of the power adapter, a sealing mechanism is added, which includes a bidirectional sleeve 21, an intermediate disk 22 and a guide block 23. A plurality of mounting holes 24 are provided on the side wall of the power supply body 1, and a bidirectional sleeve 21 is slidably installed in each mounting hole 24. The intermediate disk 22 is slidably connected in each bidirectional sleeve 21, and a plurality of guide blocks 23 are installed on the side wall of each intermediate disk 22. A plurality of guide grooves 25 are provided on the inner wall of the bidirectional sleeve 21, and the guide blocks 23 are slidably connected in the guide grooves 25. A plurality of connecting grooves 26 are symmetrically provided on the inner wall of the bidirectional sleeve 21, and two ends of the intermediate disk 22 are respectively provided with A rounded corner 27, a contraction groove 28 is provided on the inner wall of the two-way sleeve 21, and a plurality of expansion springs 29 are provided in the contraction groove 28, and a top ball 30 is provided on each expansion spring 29, and an annular groove 31 is provided on the inner wall of the mounting hole 24, and a plurality of top balls 30 respectively abut against the annular groove 31, and a return spring 32 is provided at both ends of each guide block 23, and a stop disk 33 is provided at both ends of each guide groove 25, and two return springs 32 respectively abut against the stop disks 33 at both ends, and a plurality of push rods 34 are provided on the inner wall of the air inlet shell 2, and the plurality of push rods 34 and the two-way sleeve 21 are coaxially arranged, and the push rods 34 abut against the middle disk 22.

[0030] Working principle: after the sealing of the air inlet shell 2 is completed, the multiple push rods 34 will move synchronously with the air inlet shell 2, and then the push rods 34 will press on the multiple intermediate disks 22. As the push rods 34 squeeze the corresponding side of the return spring 32, the elastic force of the return spring 32 is very small and can only provide a return function. The synchronous disk 12 moves downward accordingly. At this time, the connecting groove 26 and the two-way sleeve 21 at the lower end are in a connected state. As the air inlet shell 2 is installed on the side wall of the power supply body 1, the power supply rod 19 is also inserted into the power supply port 20. Therefore, the multiple fans 8 are in a rotating state, which will generate wind pressure inside the power supply body 1, and the inside of the power supply body 1 is dissipated by the airflow. Due to the generated wind pressure, a thrust will be generated on the intermediate disks 22 on the upper and lower sides, causing the intermediate disks 22 to slide to one side, thereby unlocking the seal between the connecting groove 26 and the two-way sleeve 21. At this time, wind with higher heat is blown out, so the power supply can be continuously dissipated, thereby ensuring the continuous operation of the power supply.

[0031] When the power supply body 1 is not installed with the air inlet shell 2, since no corresponding pressure is provided, all the intermediate disks 22 will be in the middle position. At this time, the connecting grooves 26 at both ends of the two-way sleeve 21 are in a partitioned state. Therefore, in normal state, the entire power supply body 1 is in a sealed state to prevent dust from entering.

[0032] When the two-way sleeve 21 needs to be installed, first hold the multiple top balls 30, then use the expansion spring 29 to shrink the multiple top balls 30 into the shrinkage groove 28, and then insert the two-way sleeve 21 into the installation sleeve and continue to push downward. When the multiple top balls 30 contact the annular groove 31, the top balls 30 are stuck in the annular groove 31 under the action of the expansion spring 29, thereby completing the fixation of the two-way sleeve 21.

[0033] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
