Description

Technical Field

[0001] The present invention relates to the field of battery technology, and in particular to a modular power supply and distribution component for a desktop film cutting machine. Background Art

[0002] With the rapid development of industries such as packaging, printing, and electronic manufacturing, desktop film cutting machines have gradually become key equipment in the field of small-batch precision processing due to their compact size and flexible operation. Film cutting machines use high-precision tools or lasers to cut thin film materials (such as plastics, composite materials, self-adhesive labels, etc.). As precision processing equipment, the stability and safety of the power supply and distribution system of desktop film cutting machines directly affect the operating efficiency and service life of the equipment.

[0003] Currently, the battery assembly and distribution unit adopt an integrated packaging design. The battery module and the shell are fixed by an irreversible connection method (such as screw locking or gluing). When a single battery unit is damaged, the battery assembly needs to be replaced as a whole, resulting in waste of resources and increased maintenance costs. For example, the battery pack of a certain brand of membrane cutting machine (model MX-2000) has a high degree of integration, and the replacement cost accounts for more than 60% of the maintenance cost of the whole machine. In continuous high-load operation, the chemical reaction inside the battery generates heat and accumulates, while the traditional heat dissipation solution only relies on natural convection on the surface of the shell and cannot effectively dissipate heat. Experimental data show that when the ambient temperature exceeds 35°C, the internal temperature of the existing battery pack can reach 65-75°C, causing the electrolyte to volatilize and the electrode material to expand, and eventually causing the battery to bulge, thereby reducing the service life of the host's distribution components.

[0039] A positioning groove 42 is provided on the side of the fixed box 3, and an extension block 4 is slidably inserted into the positioning groove 42. The extension block 4 can only move up and down under the limiting effect of the positioning groove 42. A movable protection component that is easy to adjust is provided on the fixed box 3. The movable protection component includes an arc gear 44. Slide grooves 43 are provided on both sides of the positioning groove 42 of the fixed box 3. The fixed box 3 is rotatably connected to a rotating shaft 45 on both sides of the arc gear 44 through bearings.

[0040] A spring-loaded clip 5 is installed at the end of the extension block 4, and a pressure sensor 51 is installed at the end of the spring-loaded clip 5.

The alarm 7 is electrically connected to the control center. The battery management system is electrically connected to the alarm 7. When a battery abnormality is detected, an alarm is sounded through the alarm 7.

[0041] The spring-loaded buckle 5 is snapped onto the predetermined groove of the host. At this time, the end of the pressure sensor 51 is pressed against the end face of the predetermined groove of the host. The pressure sensor 51 senses a certain pressure. If the battery assembly becomes loose on the host due to vibration, and the pressure value received by the pressure sensor 51 is less than the set interval, the pressure signal is transmitted to the control center. The control center controls the alarm 7 to sound an alarm to remind the user to solve the loose problem in time.

[0042] There are two groups of circular arc gears 44, which are respectively distributed on the front and rear sides of the interior of the fixed box 3 and are fixedly sleeved on the rotating shaft 45. Each group of circular arc gears 44 are meshed with each other. The arrangement of the front and rear groups of circular arc gears 44 facilitates the relative stability of the contraction or extension movement of the extension block 4. Protective blocks 41 are overlapped on both sides of the extension block 4 on the fixed box 3.

[0043] A first connecting rod 46 is fixedly sleeved on the rotating shaft 45, and the end of the first connecting rod 46 passes through the slide groove 43 and is hinged on the side of the protective block 41. Second connecting rods 461 are hinged on both sides of the protective block 41, and the bottom of the second connecting rod 461 is hinged on the fixed box 3. The setting of the slide groove 43 facilitates the positioning and movement of the first connecting rod 46 and the second connecting rod 461.

[0044] A third connecting rod 47 is fixedly sleeved on the rotating shaft 45, one end of the third connecting rod 47 passes through the slide groove 43 and is hingedly connected to a fourth connecting rod 471, the end of the fourth connecting rod 471 is hinged on the side of the extension block 4, the length of the third connecting rod 47 is greater than the length of the fourth connecting rod 471, the setting of the slide groove 43 facilitates the positioning and movement of the fourth connecting rod 471, and a limit assembly for easy adjustment is provided at the end of the rotating shaft 45, the limit assembly includes a handle 92, and the handle 92 is fixedly connected to the end of the rotating shaft 45.

[0045] When the rotating shaft 45 rotates, the circular arc gear 44 is driven to rotate, and the circular arc gears 44 on both sides mesh and rotate inward, driving the movement of the first connecting rod 46, and the second connecting rod 461 also moves accordingly, driving the protective blocks 41 on both sides to rotate around the rotating shaft 45, and also driving the third connecting rod 47 to move, and the third connecting rod 47 pulls the fourth connecting rod 471 to move downward, thereby driving the extension block 4 to move downward and contract into the fixed box 3, so that the extension block 4 can be accommodated in the fixed box 3, and the protective blocks 41 on both sides overlap the positioning groove 42 to close the positioning groove 42, thereby protecting the extension block 4, which is beneficial to the protection of the spring buckle 5 on the extension block 4 when not in use.

[0046] A groove is provided on the turning handle 92, and a movable plug-in block 93 is slidably inserted in the groove. The movable plug-in block 93 is an "L"-shaped block structure, and a buckle groove is provided at one end. A support spring 94 is fixedly connected between the movable plug-in block 93 and the groove. An annular block 9 is welded on the outer side of the turning handle 92 on the battery lower cover 1. An integrally formed limiting block 91 protrudes inside the annular block 9. An obtuse angle structure is formed between the two limiting blocks 91. The setting of the two limiting blocks 91 enables the rotating shaft 45 to rotate at a certain angle.

[0047] A limiting groove 95 is provided on the inner side of the annular block 9 between the two limiting blocks 91, and the end of the movable plug-in block 93 matches with the limiting groove 95. An elastic plug-in structure is formed between the support spring 94 and the movable plug-in block 93, so that the end of the movable plug-in block 93 is plugged into the corresponding limiting groove 95, thereby realizing the limiting fixation of the turning handle 92 and the rotating shaft 45.

[0048] A first magnetic block 96 is embedded in the end of the movable plug block 93, and a second magnetic block 97 is embedded in the inner side of the limiting groove 95 on the annular block 9. The second magnetic block 97 and the first magnetic block 96 attract each other, further realizing the relative stability of the limiting fixation of the turning handle 92 and the rotating shaft 45, thereby ensuring the stability of the extension block 4 after adjustment.

[0049] A cooling pipe 8 is embedded in the battery upper cover 2, and the cooling pipe 8 contains coolant. A circulation pipe 81 is connected to the side of the cooling pipe 8. A receiving groove is provided on the battery lower cover 1, and a heat sink 82 is fixed on the receiving groove. One end of the circulation pipe 81 passes through the heat sink 82. A ventilation groove 21 is provided on the battery upper cover 2. There are multiple ventilation grooves 21, and the multiple ventilation grooves 21 are distributed around the cooling pipe 8. The voltage regulating module is thermally connected to the cooling pipe 8 to effectively dissipate heat and ensure the stable operation of the voltage regulating module.

[0050] When the host battery is working, its heat surges upward through the ventilation groove 21, and the cooling pipe 8 surrounding the upper end evenly absorbs the heat generated by the host battery. The heat is then circulated through the circulation pipe 81 and transferred to the heat sink 82 and dissipated to the outside, which can reduce the bulging of the battery.

[0051] An opening and closing assembly that is easy to adjust is provided between the fixing box 3 and the battery cover 2. The opening and closing assembly includes a support tube 6, which is fixedly installed on the fixing box 3. A pulling top rod 61 is slidably inserted on the support tube 6. The pulling top rod 61 is in a "T"-shaped structure, and the top is fixedly connected to the bottom of the extension block 4. A first airbag 62 is bonded between the pulling top rod 61 and the support tube 6.

[0052] A movable groove is provided on the battery upper cover 2 at the opening of the ventilation groove 21, and a sealing block 66 is slidably inserted on the movable groove. The end of the sealing block 66 corresponds to the opening of the ventilation groove 21, and a second airbag 64 is bonded between the sealing block 66 and one side of the movable groove. A connecting pipe 63 is connected between the second airbag 64 and the first airbag 62, and a return spring 65 is fixedly connected between the sealing block 66 and the other side of the movable groove.

[0053] When the extension block 4 protrudes from the outside of the fixed box 3, the elastic force of the return spring 65 squeezes the sealing block 66 to move its end into the movable groove, thereby squeezing the second airbag 64. The gas in the second airbag 64 is transmitted to the first airbag 62 through the connecting tube 63. The first airbag 62 is filled with gas, and the pulling push rod 61 abuts against the extension block 4. When the extension block 4 shrinks to the inside of the fixed box 3, the extension block 4 squeezes and pulls the push rod 61 to move downward to compress the first airbag 62. The gas in the first airbag 62 is transmitted to multiple second airbags 64 through the connecting tube 63. Multiple second airbags 64 expand and squeeze the sealing block 66 to move, forming a closure on the opening of the ventilation groove 21 to prevent dust or other debris from entering the shell through the ventilation groove 21 when not in use and affecting the heat dissipation of the battery.

[0054] In actual use, by pressing the buckle groove on the movable plug block 93, the end of the movable plug block 93 is moved away from the limit groove 95, and the handle 92 is rotated to rotate the shaft 45, thereby driving the arc gear 44 to rotate, and the arc gears 44 on both sides mesh and rotate inward, driving the movement of the first connecting rod 46, and the second connecting rod 461 also moves accordingly, thereby driving the protective blocks 41 on both sides to rotate around the shaft 45 and move away from each other, and also driving the third connecting rod 47 to move, and the third connecting rod 47 pulls the fourth connecting rod 471 to move upward, thereby driving the extension block 4 to move and extend in the direction away from the fixed box 3, so that the extension block 4 extends to the outside of the fixed box 3, which is conducive to the use of the spring buckle 5 on the extension block 4, and then release the movable plug block 93, so that the elastic support spring 94 Under the action of force, the end of the movable plug block 93 is inserted into the corresponding limit groove 95, so as to realize the limit fixation of the handle 92 and the shaft 45. The second magnetic block 97 and the first magnetic block 96 attract each other, so as to further realize the relative stability of the limit fixation of the handle 92 and the shaft 45, thereby ensuring the stability of the extension block 4 after adjustment. The spring-type buckle 5 is clamped on the host. At this time, the end of the pressure sensor 51 is pressed on the end face of the predetermined groove of the host. The pressure sensor 51 feels a certain pressure. If the battery assembly on the host is loosened due to vibration, when the pressure value received by the pressure sensor 51 is less than the set interval, the pressure signal is transmitted to the control center, and the control center controls the alarm 7 to alarm to remind the user to solve the loose problem in time.

[0055] When the host battery is working, its heat flows upward through the ventilation groove 21, and the cooling pipe 8 surrounding the upper end uniformly absorbs the heat generated by the host battery, and then the heat is circulated and transferred to the heat sink 82 through the circulation pipe 81 and dissipated to the outside, so that the battery bulging can be reduced. When the extension block 4 protrudes from the outside of the fixing box 3, the elastic force of the return spring 65 squeezes the sealing block 66 to move its end into the moving groove, thereby squeezing the second airbag 64. The gas of the second airbag 64 is transferred to the first airbag 62 through the connecting pipe 63. The first airbag 62 is filled with gas, pulling the top rod 61 to abut against the extension block 4;

[0056] When not in use, the buckle groove on the movable plug block 93 is pressed to make its end away from the limit groove 95, and the handle 92 is turned to rotate the shaft 45, driving the rotation of the arc gear 44. The arc gears 44 on both sides mesh and rotate inward, driving the movement of the first connecting rod 46, and the second connecting rod 461 also moves accordingly, driving the protection blocks 41 on both sides to rotate around the shaft 45, and also driving the third connecting rod 47 to move. The third connecting rod 47 pulls the fourth connecting rod 471 to move downward, and then drives the extension block 4 to move downward and contract into the fixed box 3, so that the extension block 4 is accommodated in the fixed box 3, and the protection blocks 41 on both sides overlap on the positioning groove 42. The positioning groove 42 is closed to protect the extension block 4, which is beneficial to the protection of the spring buckle 5 on the extension block 4 when not in use. During this process, the extension block 4 squeezes and pulls the top rod 61 to move downward to compress the first airbag 62. The gas in the first airbag 62 is transmitted to the multiple second airbags 64 through the connecting tube 63. The multiple second airbags 64 expand and squeeze the sealing block 66 to move, forming a closure on the opening of the ventilation groove 21 to prevent dust or other debris from entering the shell through the ventilation groove 21 when not in use and affecting the heat dissipation of the battery. This increases the service life of the battery assembly of the host and reduces the need for disassembly or replacement between the distribution assembly and the cover.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
