DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] In order to solve the technical problem of fully cooling the notebook power supply, the structure and function of a retractable notebook power supply are described in detail below. A retractable notebook power supply includes a power supply 10, a cooling mechanism 20, a sliding mechanism 30, a driving mechanism 40, a connecting rod 50, a reciprocating rod 60, a dipping mechanism 70 and a wire release mechanism 80;

[0031] When in use, the two driving mechanisms 40 drive the two sliding mechanisms 30 to reciprocate, and the two sliding mechanisms 30 drive the multiple cooling fans 23 on the cooling mechanism 20 to rotate. The wind force generated by the rotation of the multiple cooling fans 23 cooperates with each other to fully cool the power supply 10. Further, when the two sliding mechanisms 30 reciprocate, the two sliding mechanisms 30 respectively drive the corresponding connecting rods 50 to move, and the two connecting rods 50 drive the corresponding reciprocating rods 60 to move, and the reciprocating rods 60 drive the dipping mechanism 70 to dip a small amount of coolant on the outer surface of the power supply 10, and use the volatilization of the coolant to absorb heat to further achieve a cooling effect;

[0032] The structure and function of the cooling mechanism 20 are described in detail below. The cooling mechanism 20 includes a cooling cavity 21, a sliding pipe 22 and a cooling fan 23. The cooling cavity 21 is fixedly connected to the power supply 10. The four sides of the cooling cavity 21 are rotatably connected to the cooling fan 23. The upper end of the cooling cavity 21 is fixedly connected to the sliding pipe 22.

[0033] like Figure 2 As shown, the cooling cavity 21 covers the entire power supply 10, and there is a certain gap between the power supply 10 and the cooling cavity 21, so that air can flow in the gap between the cooling cavity 21 and the power supply 10, and the four sides of the cooling cavity 21 are rotatably connected with cooling fans 23, and the corresponding two cooling fans 23 rotate in the same direction, such as the cooling fan 23 on the upper side rotates counterclockwise, such as the cooling fan 23 on the lower side rotates counterclockwise, thereby forming a wind circulation between the upper and lower cooling fans 23, the cooling fan 23 on the left side rotates counterclockwise, and the cooling fan 23 on the right side rotates counterclockwise, thereby forming a wind circulation between the left and right cooling fans 23, and the wind between the four cooling fans 23 will move relative to each other to fully cool the power supply 10;

[0034] The structure and function of the sliding mechanism 30 are described in detail below. The left and right sides of the power supply 10 are slidably connected with the sliding mechanism 30. The sliding mechanism 30 includes a sliding cavity 31, a driving bracket 32, a rack 33, a contact column 34, a storage cavity 35 and an exhaust hole 36. The driving bracket 32 ​​is fixedly connected in the sliding cavity 31. Four racks 33 are fixedly connected to the sliding cavity 31. A plurality of contact columns 34 are fixedly connected to the inner side of the sliding cavity 31. A storage cavity 35 is fixedly connected to the sliding cavity 31. A plurality of exhaust holes 36 are provided on the sliding cavity 31. The sliding cavity 31 is slidably connected to the power supply 10 through the plurality of contact columns 34. The left and right sides of the power supply 10 are slidably connected with the driving bracket 32. A compression spring I is fixedly connected between the power supply 10 and the driving bracket 32. The eight racks 33 are respectively meshed with the four cooling fans 23 for transmission.

[0035] like Figure 6 , 7 As shown in Figure 8, the sliding cavity 31 is slidably connected between the cooling cavity 21 and the power supply 10. When the sliding cavity 31 slides between the cooling cavity 21 and the power supply 10, the space between the sliding cavity 31 and the power supply 10 changes, thereby forming a certain airflow between the sliding cavity 31 and the power supply 10. When the two sliding cavities 31 reciprocate left and right, the two sliding cavities 31 cool the front and rear sides of the power supply 10.

[0036] Furthermore, the sliding cavity 31 is slidably connected to the power source 10 through a plurality of contact pins 34, thereby ensuring that the plurality of contact pins 34 and the power source 10 are in line contact, reducing the contact area with the power source 10 while ensuring that no contact pin 34 is always in contact with a fixed position on the side of the power source 10, so that when the sliding cavity 31 slides, it is ensured that the side of the power source 10 can be fully cooled;

[0037] Furthermore, the wind generated by the rotation of the four cooling fans 23 will also enter the sliding cavity 31 through the gap between the sliding cavity 31 and the power supply 10, increasing the movement of the wind in the sliding cavity 31 and further increasing the cooling effect;

[0038] The structure and function of the driving mechanism 40 are described in detail below. The left and right sides of the power supply 10 are fixedly connected with the arc gear cylinder 11. The driving mechanism 40 includes a driving fan 41 and a push column 42. The driving fan 41 is rotatably connected to the driving bracket 32. The driving fan 41 is fixedly connected with the push column 42. The push column 42 is in contact with the arc gear cylinder 11. The driving fan 41 is provided with a power mechanism I that drives it to rotate. The power mechanism I is preferably a servo motor.

[0039] Start the power mechanism I, which can be fixedly connected to the driving bracket 32, and the output shaft of the power mechanism I is connected to the driving fan 41 by transmission, and the output shaft of the power mechanism I drives the driving fan 41 to rotate, and the driving fan 41 drives the pushing column 42 thereon to move, and the pushing column 42 fits with the arc gear cylinder 11 under the pulling of the compression spring I, and the pushing column 42 moves on the edge of the arc gear cylinder 11, and the pushing column 42 pushes the driving fan 41 to move, and the driving fan 41 drives the driving bracket 32 ​​to move, and the driving bracket 32 ​​drives the sliding cavity 31 to reciprocate, and a certain wind force is generated when the driving fan 41 rotates, and the wind forces generated by the driving fans 41 on the front and rear sides are opposite, such as the driving fans 41 on the front and rear sides rotate clockwise, so that the airflow enters or is discharged from the sliding cavity 31 through the exhaust hole 36, thereby increasing the cooling effect on the power supply 10;

[0040] The structure and function of the dipping mechanism 70 are described in detail below. The two sliding cavities 31 are both hinged with connecting rods 50, and a reciprocating rod 60 is hinged between the two connecting rods 50. The dipping mechanism 70 is fixedly connected to the reciprocating rod 60, and the dipping mechanism 70 is slidably connected in the sliding pipe 22.

[0041] The dipping mechanism 70 includes a dipping outer cylinder 71, a dipping inner cylinder 72 and a closing push block 73. The dipping outer cylinder 71 is fixedly connected to the reciprocating rod 60. The dipping inner cylinder 72 is slidably connected inside the dipping outer cylinder 71. A compression spring II is fixedly connected between the dipping inner cylinder 72 and the dipping outer cylinder 71. The lower end of the dipping inner cylinder 72 is slidably connected to the closing push block 73. The upper and lower ends of the closing push block 73 are fixedly connected to closing blocks. The lower end of the closing push block 73 extends out of the dipping outer cylinder 71. The lower end of the dipping outer cylinder 71 is provided with a water outlet hole I, and the lower end of the dipping inner cylinder 72 is provided with a water outlet hole II. The two closing blocks can block the water outlet hole I or the water outlet hole II. A compression spring III is fixedly connected between the closing push block 73 and the dipping inner cylinder 72.

[0042] like Fig.10 and 11 As shown, the coolant is poured into the water dipping inner cylinder 72 in advance. When the sliding cavities 31 are close to or away from each other, the two sliding cavities 31 respectively drive the corresponding connecting rods 50 to move, the two connecting rods 50 drive the reciprocating rod 60 to move, and the reciprocating rod 60 drives the dipping mechanism 70 to reciprocate up and down. When the dipping mechanism 70 moves downward and contacts the outer surface of the power supply 10, it should be noted that the power supply 10 is a laptop power supply with a plastic shell, such as Fig.11As shown, the closing push block 73 moves downward, and the closing push block 73 moves upward under the reverse push of the power supply 10, the water outlet hole I at the lower end of the water dipping outer cylinder 71 opens for a moment, and the water outlet hole II at the lower end of the water dipping inner cylinder 72 opens for a moment, and after the water outlet hole II and the water outlet hole I are opened at the same time, the water dipping outer cylinder 71 and the water dipping inner cylinder 72 are connected, and then the coolant between the water dipping outer cylinder 71 and the water dipping inner cylinder 72 will drip onto the plastic shell on the surface of the power supply 10, and when the closing push block 73 continues to move upward, the closing push block 73 blocks the water outlet hole II, and the liquid will not flow out, and then the dipping mechanism 70 reciprocates, and the dipping mechanism 70 continuously dips the liquid on the power supply 10, and after being blown by the four driving fans 41, the coolant evaporates to cool the power supply 10;

[0043] The structure and function of the wire-releasing mechanism 80 are described in detail below. The wire-releasing mechanism 80 includes a wire-releasing shaft 81, a wire-releasing drum 82, a clamping plate 83, a clamping protrusion 84, a rotating handle 85, a wire-pressing wheel 86, a socket 87 and a clamping hole 88. The wire-releasing shaft 81 is fixedly connected with a connecting key, and the wire-releasing drum 82 is slidably connected to the connecting key. The wires of the power supply 10 are stored in a spiral groove provided on the wire-releasing drum 82, and the other end of the wires is connected to the socket 87. The wire-releasing shaft 81 is rotatably connected with a clamping plate 83, and the clamping protrusion 84 is provided There are multiple, multiple clamping protrusions 84 and the clamping plate 83 are fixedly connected with compression springs IV, the pay-off shaft 81 is fixedly connected with a rotating handle 85, the rotating handle 85 is provided with multiple clamping holes 88, multiple clamping protrusions 84 are respectively clamped in the multiple clamping holes 88, the pressing wheel 86 is in contact with the pay-off drum 82, the inside of the two sliding cavities 31 are rotatably connected with the pay-off shaft 81, the multiple clamping protrusions 84 are respectively slidably connected to the corresponding two moving cavities 31, and the two sockets 87 are respectively received in the two receiving cavities 35;

[0044] like Fig.12 , 13 As shown in FIG14 , the rotating handle 85 is rotated, and the rotating handle 85 drives the pay-off shaft 81 to rotate, and the pay-off shaft 81 drives the pay-off drum 82 to rotate, and the pay-off drum 82 pays out the wire, thereby changing the length that the socket 87 can extend, and the wire pressing wheel 86 can ensure that the wire is in the spiral groove on the pay-off drum 82, and the rotation of the rotating handle 85 is limited by a plurality of clamping protrusions 84, so that the rotating handle 85 will not rotate easily, and each rotation of the rotating handle 85 needs to overcome a plurality of clamping protrusions 84, thereby controlling the length of the wire extending;

[0045] like Figure 3 As shown, further, a support mechanism 90 is provided, the support mechanism 90 includes a support rod 91 and a support bottom plate 92, the support rod 91 and the support bottom plate 92 are interference-connected, two support mechanisms 90 are provided, and the two support mechanisms 90 are respectively interference-connected on the left and right sides of the cooling mechanism 20;

[0046] When the dipping mechanism 70 drops the coolant on the power supply 10, in order to prevent the coolant from flowing to other places due to the tilt of the power supply 10 and causing the power supply 10 to leak, it is necessary to ensure that the power supply 10 is set horizontally. Therefore, a support mechanism 90 is provided. The support rod 91 is interference fit between the power supply 10 and the support base plate 92, and can be installed by rubber or other materials, so that the support rod 91 will generate a certain resistance when moving, preventing the power supply 10 from moving randomly. The support rod 91 and the support base plate 92 are adjusted to make the power supply 10 set horizontally, ensuring that the power supply 10 is also set horizontally on an uneven ground to ensure that the coolant does not flow to other places.
