Description

Technical Field

[0001] This invention relates to the field of multi-source power supply technology, and more specifically to a portable multi-source power supply device. Background Technology

[0002] Portable multi-source power supply devices are miniaturized power supply equipment that integrates multiple energy replenishment methods. They are mainly used to provide stable power to electronic devices in outdoor activities, emergency power supply, or mobile scenarios.

[0003] Chinese patent CN221098206U discloses an outdoor multi-source power supply device, including a power supply component comprising a power supply body and a handle, the handle being disposed on the power supply body; and a support component disposed on the handle, including a support member, a locking member, a positioning member, a pushing member, and a blocking member. This prior art avoids direct contact between the power supply component and the ground during use, preventing easy contamination from dust and moisture. Furthermore, the support component can be stored away when carrying the power supply component, thus facilitating its transport.

[0004] However, during outdoor use, some places have strong sunlight, and the sunlight shining on the surface of the multi-source power supply device may cause the temperature of the device to rise. Since it may be used outdoors for a long time, the multi-source power supply device will be exposed to sunlight for a long time, resulting in the device being overheated for an extended period of time. This can cause the control panel of the multi-source power supply device to lag or become unresponsive. Summary of the Invention

[0015] The snap ring is installed inside the sliding block, and the rotating rod is connected to the sun visor; the storage slot is opened on the rotating rod, and the two ends of the elastic element are respectively connected to the snap rod and the rotating rod; by adjusting the tilt angle of the sun visor, the rotating rod drives the snap rod to rotate in the snap ring, and the snap rod and the snap ring snap together.

[0016] Preferably, the filtration mechanism includes a drive assembly, a cleaning brush, an elastic element, and a filter plate;

[0017] The drive assembly is installed inside the sliding part; the filter plate is installed on the power supply mechanism; the cleaning brush is connected to the drive assembly and moves up and down on the surface of the filter plate with the drive assembly; the two ends of the elastic element are respectively connected to the power supply mechanism and the cleaning brush.

[0018] Preferably, the drive assembly includes a lifting groove, a conical section, and a connecting rod;

[0019] The lifting groove is located on the power supply mechanism and at the bottom of the sliding part; the two ends of the connecting rod are respectively connected to the cleaning brush and the second conical part; the second conical part is engaged with the first conical part, and the first conical part moves along the second conical part, pushing the second conical part and the cleaning brush at the bottom of the connecting rod to rise and fall.

[0020] Preferably, the blowing mechanism includes a pull rope, a guide rod, a spring, a piston plate, a piston cylinder, and an air outlet assembly;

[0021] The piston cylinder is installed inside the power supply mechanism, and the two ends of the pull rope are connected to the sliding block and the piston plate, respectively. The piston plate is movably connected inside the piston cylinder. The guide rod is installed inside the piston cylinder, and the piston plate is sleeved on the guide rod. The two ends of the spring are connected to the piston cylinder and the piston plate, respectively. The air outlet assembly is connected to the piston cylinder. The pull rope moves with the sliding block, pulling the piston plate to move along the guide rod inside the piston cylinder.

[0022] Preferably, the air outlet assembly includes a one-way air inlet valve, a one-way air outlet valve, an air blowing pipe, and a heat sink;

[0023] The outlet end of the one-way inlet valve is connected to the piston cylinder; the inlet end of the one-way outlet valve is connected to the piston cylinder, and its outlet end is connected to the air blowing pipe; the heat sink is installed inside the power supply mechanism, and the outlet end of the air blowing pipe faces the heat sink.

[0024] Preferably, the adsorption mechanism includes a connecting tube, a spring, a conical tube, and a telescopic tube;

[0025] The connecting pipe connects to the piston cylinder at the end furthest from the air outlet assembly; the connecting pipe at the end furthest from the piston cylinder connects to the telescopic pipe; the two ends of the spring are respectively connected to the tapered pipe and the power supply mechanism; the air inside the telescopic pipe is input or discharged as the piston plate moves.

[0026] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:

[0027] When used outdoors, place the power supply unit on a table with the tapered tube on the table. Then, pull the sunshade from above the power supply unit towards the control panel. The sunshade pulls the sliding block along the sliding part, positioning the sunshade above the control panel to provide shade. The sunshade can then be rotated according to the direction of sunlight. This causes the sunshade to rotate the rotating rod within the locking ring. The locking rod engages with the locking ring. As the sunshade and rotating rod rotate, the elasticity of the first elastic element causes the locking rod to retract into the storage groove after being squeezed by the locking ring, and then engage with the locking ring again. This allows the sunshade to be pulled to provide shade for the control panel. Furthermore, the engagement of the locking rod and locking ring ensures that the adjusted sunshade is positioned, preventing sunlight from shining directly onto the control panel and causing it to overheat or jam.

[0028] When the sliding block moves along the sliding part, it pulls the pull rope to move, and the pull rope pulls the piston plate to move in the inner cavity of the piston cylinder. The piston plate moves along the guide rod, which in turn causes the piston plate to compress and store the spring. When the piston plate moves toward the one-way air outlet valve, it delivers the air in the inner cavity of the piston cylinder to the air blowing pipe, and then blows away the dust on the surface of the heat sink through the air blowing pipe, thereby ensuring that the surface of the heat sink is clean and thus avoiding a decrease in the heat conduction efficiency of the heat sink.

[0029] Because the bottom of the tapered tube is in contact with the tabletop, when the piston plate moves along the guide rod toward the one-way air intake valve, it draws air from the inner cavity of the telescopic tube into the piston cylinder. The negative pressure air in the inner cavity of the telescopic tube allows the power supply mechanism to be placed stably on the tabletop, thereby improving the stability of the power supply mechanism and preventing it from tipping over in strong winds or other situations outdoors.

[0030] During the operation of the power supply mechanism, an external air is drawn into the mechanism by a fan inside the mechanism, thereby cooling the components inside the mechanism. The filter plate filters dust and other particles from the air. When the first conical part moves along the second conical part, the first conical part and the second conical part engage, causing the second conical part to rise and fall intermittently. This, in turn, causes the cleaning brush to rise and fall, thereby cleaning the dust on the surface of the filter plate and preventing the dust on the filter plate from affecting ventilation.

[0039] Example 1, as Figures 1-7 As shown, the present invention proposes a portable multi-source power supply device, which includes a shielding mechanism, a filtering mechanism, an air blowing mechanism, an adsorption mechanism, a power supply mechanism 1, and a control panel 2, wherein the control panel 2 is installed on the power supply mechanism 1.

[0040] The shielding mechanism is installed on the power supply mechanism 1;

[0041] The filter mechanism is installed on the power supply mechanism 1 and is used to block dust from entering the power supply mechanism 1;

[0042] The air blowing mechanism is installed on the power supply mechanism 1 and is used to clean the surface of the power supply mechanism 1;

[0043] The adsorption mechanism is installed inside the power supply mechanism 1 and is used to adsorb onto the desktop;

[0044] The shading mechanism includes a sliding assembly, a connecting assembly, a sunshade 32, and two sliding parts 3; both sliding parts 3 are mounted on the power supply mechanism 1 and are used to connect to the sliding assembly; the connecting assembly is mounted on the moving end of the sliding assembly; the sunshade 32 is mounted on the connecting assembly and moves along the sliding part 3; the sunshade 32 is pulled up and down on the control panel 2 via the sliding assembly along the sliding part 3, and the tilt angle of the sunshade 32 is adjusted via the connecting assembly.

[0045] The control panel 2 is shielded by a shielding mechanism to prevent sunlight from shining on its surface for a long time, and the dust is blocked and cleaned by a filtering mechanism, thereby ensuring that the power supply mechanism 1 is cooled down.

[0046] A handle 31 for carrying is installed on the sliding part 3.

[0047] The sliding assembly includes a tapered portion 4, a limiting plate 5, and a sliding block 6;

[0048] The tapered part 4 is slidably connected to the sliding part 3, the sliding block 6 is connected to the tapered part 4, and the connecting assembly is installed in the sliding block 6; the limiting plate 5 is connected to the tapered part 4; the sliding block 6 and the limiting plate 5 are attached to the sliding part 3 on the side near the sliding part 3.

[0049] Pulling the sunshade 32 moves the conical part 4 along the sliding part 3. At this time, the conical part 4 and the conical part 13 are engaged, causing the conical part 13 to rise and fall intermittently, thereby driving the connecting rod 14 to rise and fall, and then driving the cleaning brush 15 to clean the dust on the surface of the filter plate 17.

[0050] The connecting components include a snap ring 7, a rotating rod 8, an elastic element 9, a snap rod 10, and a storage slot 11;

[0051] The snap ring 7 is installed inside the sliding block 6, and the rotating rod 8 is connected to the sunshade 32; the storage groove 11 is opened on the rotating rod 8, and the two ends of the elastic element 9 are respectively connected to the snap rod 10 and the rotating rod 8; when the tilt angle of the sunshade 32 is adjusted, the rotating rod 8 drives the snap rod 10 to rotate on the snap ring 7, and the snap rod 10 and the snap ring 7 snap together.

[0052] The sun visor 32 drives the rotating rod 8 to rotate within the locking ring 7. At this time, through the locking of the locking rod 10 and the locking ring 7, the locking rod 10 is squeezed into the inner cavity of the receiving groove 11 by the locking ring 7. Subsequently, when the locking rod 10 is located in the recess of the locking ring 7, the locking rod 10 extends into the recess of the locking ring 7 again through the elasticity of the elastic element 9. At this time, through the locking of the locking ring 7 and the locking rod 10, the rotated sun visor 32 is limited and fixed.

[0053] Example 2, as Figures 3-5 As shown, the portable multi-source power supply device proposed in this invention, compared with Embodiment 1, has a filtering mechanism that includes a drive assembly, a cleaning brush 15, an elastic element 16, and a filter plate 17.

[0054] The drive assembly is installed inside the sliding part 3; the filter plate 17 is installed on the power supply mechanism 1; the cleaning brush 15 is connected to the drive assembly and moves up and down on the surface of the filter plate 17 with the drive assembly; the two ends of the elastic element 16 are respectively connected to the power supply mechanism 1 and the cleaning brush 15.

[0055] The fan inside the power supply mechanism 1 draws outside air into the power supply mechanism 1, thereby cooling the components inside the power supply mechanism 1. Then, the air entering the inner cavity of the power supply mechanism 1 is filtered through the filter plate 17. When the conical part 13 rises and falls, it drives the cleaning brush 15 to clean the surface of the filter plate 17.

[0056] The drive assembly includes a lifting groove 12, a conical section 13, and a connecting rod 14;

[0057] The lifting groove 12 is opened on the power supply mechanism 1 and located at the bottom of the sliding part 3; the two ends of the connecting rod 14 are respectively connected to the cleaning brush 15 and the second conical part 13; the second conical part 13 is engaged with the first conical part 4, and the first conical part 4 moves along the second conical part 13, pushing the second conical part 13 and the cleaning brush 15 at the bottom of the connecting rod 14 to rise and fall.

[0058] When the conical part 14 moves along the sliding part 3, the conical part 14 is engaged by the conical part 2 13. The convex and concave parts of the conical part 14 and the conical part 2 13 are interlocked, thereby driving the conical part 2 13 to rise and fall. This, in turn, drives the cleaning brush 15 at the bottom of the connecting rod 14 to rise and fall on the filter plate 17, thereby cleaning the dust on the surface of the filter plate 17.

[0059] Example 3, as Figures 1-5 and Figure 7 As shown, the portable multi-source power supply device proposed in this invention, compared with Embodiment 2, the air blowing mechanism of this embodiment includes a pull rope 18, a guide rod 19, a spring 20, a piston plate 21, a piston cylinder 30, and an air outlet assembly;

[0060] The piston cylinder 30 is installed inside the power supply mechanism 1. The two ends of the pull rope 18 are connected to the sliding block 6 and the piston plate 21, respectively. The piston plate 21 is movably connected inside the piston cylinder 30. The guide rod 19 is installed inside the piston cylinder 30, and the piston plate 21 is sleeved on the guide rod 19. The two ends of the spring 20 are connected to the piston cylinder 30 and the piston plate 21, respectively. The air outlet assembly is connected to the piston cylinder 30. The pull rope 18 moves with the sliding block 6, pulling the piston plate 21 to move along the guide rod 19 inside the piston cylinder 30.

[0061] The power supply mechanism 1 has a groove for accommodating the pull rope 18, so that when the sliding block 6 moves along the sliding part 3, the pull rope 18 can be accommodated in the groove on the power supply mechanism 1.

[0062] When the sliding block 6 pulls the rope 18 to move, it drives the piston plate 21 to move in the inner cavity of the piston cylinder 30, thereby blowing the air in the inner cavity of the piston cylinder 30 out through the one-way exhaust valve 23 and the air blowing pipe 24. When the piston plate 21 moves away from the one-way intake valve 22, it draws the outside air into the piston cylinder 30.

[0063] The air outlet assembly includes a one-way air inlet valve 22, a one-way air outlet valve 23, an air blowing pipe 24, and a heat sink 25;

[0064] The outlet end of the one-way air inlet valve 22 is connected to the piston cylinder 30; the inlet end of the one-way air outlet valve 23 is connected to the piston cylinder 30, and its outlet end is connected to the air blowing pipe 24; the heat sink 25 is installed in the power supply mechanism 1, and the outlet end of the air blowing pipe 24 faces the heat sink 25.

[0065] The heat sink 25 extends into the power supply mechanism 1 and contacts the components inside the power supply mechanism 1, thereby providing auxiliary heat dissipation to the components inside the power supply mechanism 1 from the side.

[0066] Example 4, as Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the portable multi-source power supply device proposed in this invention, compared with Embodiment 3, has an adsorption mechanism including a connecting tube 26, a spring 27, a conical tube 28, and a telescopic tube 29.

[0067] The connecting pipe 26 connects to the end of the piston cylinder 30 away from the air outlet assembly; the end of the connecting pipe 26 away from the piston cylinder 30 connects to the telescopic pipe 29; the two ends of the spring 27 are respectively connected to the tapered pipe 28 and the power supply mechanism 1; the air in the inner cavity of the telescopic pipe 29 is input or discharged as the piston plate 21 moves.

[0068] When the piston plate 21 moves toward the one-way air intake valve 22, it draws air from the inner cavity of the telescopic tube 29 into the piston cylinder 30, creating a negative pressure in the telescopic tube 29. This negative pressure air in the inner cavity of the telescopic tube 29 allows the power supply mechanism 1 to be attached to the desktop via the control panel 2.

[0069] In summary, in this invention, the power supply mechanism 1 is placed on a table, with the tapered tube 28 fitting against the table. Then, the sunshade 32 is pulled towards the control panel 2, causing the tapered part 4 to move along the sliding part 3, thus allowing the sunshade 32 to cover the control panel 2. The sunshade 32 can be rotated, causing the rotating rod 8 to rotate, which in turn causes the locking rod 10 to rotate. The locking rod 10 engages with the locking ring 7, and the rotating rod 8 causes the locking rod 10 to rotate within the locking ring 7. Through the interlacing of the locking ring 7 and the locking rod 10, and the elasticity of the elastic element 9, the locking rod 10 retracts into the storage groove 11, then extends out of the storage groove 11 again to engage with the locking ring 7, thus completing the positioning of the rotated sunshade 32 and providing sun protection for the control panel 2.

[0070] When the sunshade 32 pulls the sliding block 6 to move along the sliding part 3, the sliding block 6 pulls the pull rope 18, and the pull rope 18 pulls the piston plate 21 to move along the guide rod 19, so that the piston plate 21 squeezes the air in the piston cylinder 30 toward the one-way air outlet valve 23, and then blows it out to the surface of the heat sink 25 through the air blowing pipe 24, thereby blowing away the dust on the heat sink 25 and preventing the dust from affecting the heat dissipation performance of the heat sink 25.

[0071] When the piston plate 21 moves toward the one-way air outlet valve 23, it draws the air in the telescopic tube 29 into the piston cylinder 30 along the connecting tube 26, thereby creating a negative pressure in the telescopic tube 29, which then adheres to the tabletop, thus fixing the power supply mechanism 1 to the tabletop.

[0072] When the sunshade 32 moves the sliding block 6 along the sliding part 3, the cone-shaped part 1 4 and the cone-shaped part 2 13 on the sliding part 3 move alternately, thereby causing the cone-shaped part 2 13 to rise and fall intermittently, thereby causing the connecting rod 14 to rise and fall, thereby causing the cleaning brush 15 to rise and fall, and then the dust on the outer surface of the filter plate 17 is cleaned by the cleaning brush 15. Then, during the use of the power supply mechanism 1, the external air is drawn into the power supply mechanism 1 through the heat sink in the power supply mechanism 1, thereby dissipating heat from the components inside the power supply mechanism 1.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
