Description

Technical Field

[0001] This invention relates to the field of dual-mode heterogeneous power management device technology, specifically to a dual-mode heterogeneous power management device and method compatible with both dry cell batteries and lithium batteries. Background Technology

[0002] Currently, laser levels are important leveling tools in fields such as construction, interior decoration, and engineering surveying, and their portability and battery life directly affect construction efficiency. To meet the power supply needs of different usage scenarios, existing power supply solutions for laser levels are mainly divided into the following three categories: built-in lithium battery power supply, dry cell battery swapping solution, and external quick-release lithium battery power supply solution.

[0003] Each of the three methods has its advantages and disadvantages. If a built-in lithium battery is used, the user cannot disassemble it themselves. Once the battery is depleted, the entire device must be charged. It cannot be used while charging, and if the battery is damaged or fails, the entire device will malfunction. If a dry cell battery is used, a new battery can be replaced when the battery is depleted. However, dry cell batteries have high internal resistance and wear out quickly. Under the same charge, the actual power consumption of a dry cell battery is far less than that of a lithium battery. The cost of relying on dry cell batteries for power in the long term is much higher than that of lithium batteries, and it is not environmentally friendly. If an external quick-release lithium battery is used, the lithium battery can be removed and charged separately. Once the battery is depleted, another battery can be replaced at any time. However, external lithium batteries are expensive. Summary of the Invention

[0013] A groove formed inside the enclosure and a movable block slidably connected inside the groove;

[0014] The first limiting plates are set on both sides of the moving block and are used to contact and limit the battery compartment.

[0015] Preferably, the placement mechanism further includes:

[0016] A sliding connecting rod inside the enclosure and a suction cup connected to the connecting rod are used to adhere to and fix the outer wall of the battery compartment.

[0017] The placement box is installed at the end of the connecting rod away from the suction cup, and the cover plate is installed inside the placement box.

[0018] Preferably, the placement mechanism further includes:

[0019] A first movable rod and a second limiting plate connected to the first movable rod are slidably connected inside the placement box;

[0020] The card holder is located inside the placement box, and the second limiting plate engages with the card holder.

[0021] Preferably, the placement mechanism further includes:

[0022] A second channel is provided inside the base plate, and the first channel is connected to the second channel;

[0023] The telescopic rod and the second movable rod are installed under the base plate;

[0024] The airbags located inside the outer frame and the ventilation openings inside the airbags are used to supply air to the bottom of the built-in battery pack.

[0025] Preferably, the placement mechanism further includes:

[0026] Installed on the first outer ring below the placement box;

[0027] A second outer ring is provided outside the second moving rod, and a telescopic column is installed below the second outer ring;

[0028] The base is located on the telescopic end of the telescopic column, and the second suction strip is located below the base.

[0029] This invention provides a dual-mode heterogeneous power management method compatible with both dry cell batteries and lithium batteries, comprising the following steps:

[0030] S1. When in use, the built-in battery pack in the battery compartment uses lithium batteries. The Hall sensor in the battery compartment senses the magnet of the lithium battery and identifies the power supply as a 3.7V lithium battery.

[0031] S2. When the lithium battery is low, connect the enclosure to the battery compartment and place the base on the table.

[0032] S3. After removing the lithium battery, place it on the bottom plate inside the box and press the bottom plate to trigger the airbag to blow air.

[0033] S4. Place the dry cell battery in the battery compartment. The power supply is recognized as a 3.0V dry cell battery.

[0034] This invention provides a dual-mode heterogeneous power management device and method compatible with both dry cell batteries and lithium batteries. It offers the following advantages:

[0035] 1. This dual-mode heterogeneous power management device and method, compatible with both dry cell and lithium batteries, utilizes a battery compartment with a built-in battery pack. The battery compartment is compatible with both lithium and dry cell batteries. A single 3.7V, 1000mAh lithium battery and two AA dry cell batteries share the same battery compartment. The product comes pre-installed with a 1000mAh lithium battery. When the lithium battery is depleted, it can be removed for individual charging. After removing the lithium battery, two AA dry cell batteries can be installed and used to power the product. This design combines the environmental friendliness and low electricity cost of lithium batteries with the convenience and speed of battery swapping of dry cell batteries. It achieves a balance of convenience, economy, and battery life by using either lithium or dry cell batteries.

[0036] 2. This dual-mode heterogeneous power management device and method, compatible with both dry cell batteries and lithium batteries, utilizes a battery compartment and an internal battery pack. Since the voltage of a lithium battery in a depleted state is similar to that of a fully charged dry cell battery, the product needs to identify whether the current power supply is a 3.7V lithium battery or a 3.0V dry cell battery when displaying battery level and undervoltage protection. By embedding a magnetic Hall effect sensor module within the battery compartment and placing a magnet in the same location for the lithium battery, when a lithium battery is inserted, the Hall effect sensor detects the magnet and identifies the power supply as a 3.7V lithium battery. When a AA dry cell battery is inserted, since there is no magnet to detect the Hall effect sensor, the power supply is identified as a 3.0V dry cell battery. This facilitates the display of battery level and the type of battery used.

[0037] 3. This dual-mode heterogeneous power management device and method, compatible with both dry-cell and lithium batteries, utilizes a placement mechanism. With the cooperation of a surrounding panel, a groove, a movable block, and a first handle, the first suction strip on the first limiting plate is attracted and fixed to the outer wall of the battery compartment, achieving rapid positioning of the surrounding panel outside the battery compartment. Simultaneously, a connecting rod connects the suction cup and the placement box; pushing the placement box allows the suction cup to be attracted to the battery compartment a second time, forming a double fixation. Because the bottom of the battery compartment is uneven, this method fixes the battery compartment to the surrounding panel and the placement box, securing the battery compartment by fixing the placement box, thus preventing inconvenience or battery drop caused by the battery compartment shaking or slipping when the user opens the battery cover.

[0038] 4. This dual-mode heterogeneous power management device and method, compatible with both dry cell and lithium batteries, provides independent storage locations for lithium batteries or dry cell batteries on the base plate through a placement mechanism. This allows for orderly placement after battery replacement, preventing loss or short circuits caused by careless placement. When the base plate is pressed, it moves downward within the outer frame, compressing the telescopic rod and airbag. Gas from the airbag is expelled upward through the vent, the second channel, and the first channel, providing continuous airflow to the bottom of the lithium battery or dry cell battery, effectively removing moisture and accelerating heat dissipation from the battery surface. Simultaneously, the downward movement of the base plate drives the second moving rod and the second outer ring to compress the telescopic column, transmitting force to the base and causing the second suction strip to adhere and fix to the tabletop, thus locking the entire placement mechanism in position during operation.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0051] like Figures 1-10 As shown, the present invention provides a technical solution: a dual-mode heterogeneous power management device and method compatible with dry cell batteries and lithium batteries, which will be described as follows.

[0052] Including battery compartment 1, it also includes:

[0053] Battery spring circuit board 8 installed inside battery compartment 1 and Hall sensor 9 mounted on battery spring circuit board 8.

[0054] The built-in battery pack 6 is located inside the battery compartment 1;

[0055] Battery cover 2 installed on battery compartment 1 and dry cell electrode plate 5 disposed on battery cover 2;

[0056] The enclosure 3 is installed outside the battery compartment 1;

[0057] The placement mechanism 4 is installed on the enclosure 3. The placement mechanism 4 includes an outer frame 411, a base plate 412 slidably connected inside the outer frame 411, a first channel 413 opened inside the base plate 412, and a pad 415 disposed inside the first channel 413. The base plate 412 is used to drive the pad 415 to move in the vertical direction.

[0058] When using the device, the laser level is powered by the battery compartment 1. When the built-in battery pack 6 runs out of power, the user can manually replace the built-in battery pack 6 by adjusting the placement mechanism 4.

[0059] The built-in battery pack 6 is a lithium battery 7. The lithium battery 7 has an external mounting block 10. The mounting block 10 has a magnet inside. The Hall sensor 9 is adapted to the magnet.

[0060] When used for the first time, the built-in battery pack 6 in the battery compartment 1 uses lithium battery 7. One end of lithium battery 7 is in the battery cover 2 and the other end is in the battery spring circuit board 8. Since the magnet on the outside of lithium battery 7 is compatible with Hall sensor 9, when using lithium battery 7, Hall sensor 9 in battery compartment 1 senses the magnet of the battery and identifies the power supply as 3.7V lithium battery 7.

[0061] The built-in battery pack 6 is configured as a dry cell battery 11, which is compatible with the dry cell battery electrode plate 5.

[0062] When the lithium battery 7 is low on power, the user manually replaces it with a dry cell battery 11. At this time, the built-in battery pack 6 in the battery compartment 1 uses dry cell batteries 11. One end of the dry cell battery 11 is inside the battery cover 2, in contact with the dry cell battery electrode plate 5 inside the battery cover 2, and the other end is located at the battery spring circuit board 8. Since there is no longer a magnetic sensor 9 inside the battery compartment 1, the power supply is identified as the 3.0V dry cell battery 11.

[0063] By setting up battery compartment 1 and built-in battery pack 6, battery compartment 1 is compatible with lithium battery 7 and dry cell battery 11. One 3.7V, 1000mAh lithium battery 7 and two AA dry cell batteries 11 share one battery compartment 1. The product comes with a 1000mAh lithium battery 7. When the lithium battery 7 is depleted, it can be removed and charged separately. After removing the lithium battery 7, two AA dry cell batteries 11 can be installed and used to power the product. This combines the environmental friendliness and low power cost of lithium battery 7 with the convenient and quick battery swapping advantages of dry cell battery 11.

[0064] By configuring the battery compartment 1 and the built-in battery pack 6, since the power supply voltage of the lithium battery 7 in a depleted state is similar to that of the dry cell battery 11 in a fully charged state, the product needs to identify whether the current power supply is the 3.7V lithium battery 7 or the 3.0V dry cell battery 11 when it wants to display the power level and undervoltage protection. A magnetic Hall sensor module 9 is built into the battery compartment 1, and a magnet is placed in the same position as the lithium battery 7. When the lithium battery 7 is inserted into the battery compartment 1, the Hall sensor 9 senses the magnet and identifies the power supply as the 3.7V lithium battery 7. When the battery compartment 1 is filled with AA dry cell batteries 11, since there is no magnet to sense the Hall sensor 9, the power supply is identified as the 3.0V dry cell battery 11. This facilitates the display of the power level and the type of battery used.

[0065] The placement mechanism 4 also includes:

[0066] A groove 401 is formed inside the enclosure 3 and a movable block 402 is slidably connected inside the groove 401. A first handle is provided on the outside of the movable block 402.

[0067] The first limiting plate 403 is provided on both sides of the movable block 402, and the first limiting plate 403 near the battery compartment 1 is provided with a first suction strip on its outside.

[0068] A connecting rod 406 slidably connected inside the enclosure 3 and a suction cup 407 connected to the connecting rod 406;

[0069] The placement box 404 is installed on the end of the connecting rod 406 away from the suction cup 407, and the cover plate 405 is installed inside the placement box 404.

[0070] The process of using placement mechanism 4 to fix the position of battery compartment 1:

[0071] The user places the enclosure 3 outside the battery compartment 1 and manually presses the handles on both sides of the battery compartment 1. The handles drive the moving block 402 to slide inside the groove 401 until the first limiting plate 403 with the first suction strip approaches the outer wall of the battery compartment 1. The first suction strip gradually adheres to and is fixed to the battery compartment 1. The user then manually pushes the placement box 404, which drives the connecting rod 406 and the suction cup 407 to move towards the battery compartment 1. The suction cup 407 adheres to and is fixed to the battery compartment 1.

[0072] The placement mechanism 4 also includes:

[0073] A first movable rod 408 and a second limiting plate 409 are slidably connected inside the placement box 404. The first movable rod 408 is externally connected to a second handle.

[0074] The card slot 410 is located inside the placement box 404. The second limiting plate 409 is engaged with the card slot 410. When the user adjusts the position of the placement box 404, he / she can manually pull or push the second handle to control the relative position between the first moving rod 408 and the card slot 410 through the second handle.

[0075] A second channel 414 is formed inside the base plate 412, and the first channel 413 is connected to the second channel 414;

[0076] The telescopic rod 424 and the second movable rod 416 are installed below the base plate 412;

[0077] An airbag 417 is disposed inside the outer frame 411 and a vent 418 is opened inside the airbag 417.

[0078] The first outer ring 419 is installed below the placement box 404 and is made of magnetic material.

[0079] The second outer ring 420 is disposed outside the second moving rod 416 and the telescopic column 421 is installed below the second outer ring 420. The second outer ring 420 is made of magnetic material. In the initial state, the first outer ring 419 and the second outer ring 420 are attracted and fixed together.

[0080] The base 422 is located on the telescopic end of the telescopic column 421, and the second suction strip 423 is located below the base 422.

[0081] The working process of using the placement mechanism 4 to store lithium battery 7 or dry cell battery 11:

[0082] The user places the battery compartment 1 on the table, at which point the base 422 rests on the table. The user then manually opens the battery cover 2 and removes the lithium battery 7 or dry cell battery 11 from the battery compartment 1.

[0083] After the user takes the lithium battery 7, they place the end of the lithium battery 7 without the magnetic strip on the base plate 412, with the lithium battery 7 positioned within the outer frame 411. Gently press the base plate 412 manually. As the lithium battery 7 presses down on the base plate 412, the base plate 412 begins to move downwards within the outer frame 411, compressing the telescopic rod 424 and the airbag 417. During this compression, the gas in the airbag 417 moves upwards through the vent 418 to the first channel 413 and the second channel 414, thus providing airflow to the bottom of the lithium battery 7. Simultaneously, during the downward press, the base plate 412 presses down on the second moving rod 416, which in turn moves the second outer ring 420 downwards, compressing the telescopic column 421. The telescopic column 421 transmits force to the base 422, promoting the adhesion and fixation of the second suction strip 423 below the base 422 to the tabletop.

[0084] After the user takes out the dry cell batteries 11, they place the two batteries 11 on the pads 415 of the two first channels 413 respectively, and gently press the base plate 412 manually. As the dry cell batteries 11 press down on the pads 415, the base plate 412 and the pads 415 begin to move downward in the outer frame 411, squeezing the telescopic rod 424 and the airbag 417. During the squeezing process, the gas in the airbag 417 moves upward through the vent 418 to the first channel 413 and the second channel 414, thereby supplying air to the bottom of the dry cell batteries 11. During the pressing process, the base plate 412 presses down on the second moving rod 416. The second moving rod 416 drives the second outer ring 420 to move downward, squeezing the telescopic column 421. The telescopic column 421 transmits the force to the base 422, promoting the second suction strip 423 under the base 422 to adhere and fix to the table.

[0085] By setting up the placement mechanism 4, with the cooperation of the enclosure 3, the groove 401, the moving block 402, and the first handle, the first suction strip on the first limiting plate 403 is attracted and fixed to the outer wall of the battery compartment 1, realizing the rapid positioning of the enclosure 3 outside the battery compartment 1. At the same time, the suction cup 407 and the placement box 404 are connected by the connecting rod 406. Pushing the placement box 404 will cause the suction cup 407 to be attracted to the battery compartment 1 a second time, forming a double fixation. Since the bottom of the battery compartment 1 is not flat, the battery compartment 1 is fixed to the enclosure 3 and the placement box 404 in this way. The battery compartment 1 is fixed by fixing the placement box 404, which avoids the inconvenience of operation or the battery falling out when the user holds the battery compartment 1 to open the battery cover 2 due to the battery compartment 1 shaking or slipping.

[0086] By setting up the placement mechanism 4, an independent storage position is provided on the base plate 412 for the lithium battery 7 or dry cell battery 11, so that the batteries can be placed in an orderly manner after replacement, avoiding loss or electrode short circuit caused by random placement. When the base plate 412 is pressed, the base plate 412 moves down in the outer frame 411 and squeezes the telescopic rod 424 and the airbag 417. The gas in the airbag 417 is discharged upward through the vent 418, the second channel 414 and the first channel 413, providing a continuous airflow to the bottom of the lithium battery 7 or dry cell battery 11, effectively removing moisture and accelerating heat dissipation from the battery surface. At the same time, the downward movement of the base plate 412 drives the second moving rod 416 and the second outer ring 420 to compress the telescopic column 421, transmitting force to the base 422 and causing the second suction strip 423 to be attracted and fixed to the table, realizing the position locking of the entire placement mechanism 4 during operation.

[0087] Working principle: When using the device, the laser level is powered by the battery compartment 1. When the built-in battery pack 6 runs out of power, the user can manually replace the built-in battery pack 6 by adjusting the placement mechanism 4.

[0088] When used for the first time, the built-in battery pack 6 in the battery compartment 1 uses lithium battery 7. One end of lithium battery 7 is in the battery cover 2 and the other end is in the battery spring circuit board 8. Since the magnet on the outside of lithium battery 7 is compatible with Hall sensor 9, when using lithium battery 7, Hall sensor 9 in battery compartment 1 senses the magnet of the battery and identifies the power supply as 3.7V lithium battery 7.

[0089] When the lithium battery 7 is low on power, the user can manually replace it with a dry cell battery 11. In this case, the built-in battery pack 6 in the battery compartment 1 uses a dry cell battery 11. One end of the dry cell battery 11 is in the battery cover 2 and is in contact with the dry cell battery electrode plate 5 in the battery cover 2, and the other end is located at the battery spring circuit board 8.

[0090] Since the Hall sensor 9 inside the battery compartment 1 is no longer detected by magnets, the power supply is identified as a 3.0V dry cell battery 11.

[0091] When replacing the built-in battery pack 6, the user places the battery compartment 1 on a table, at which point the base 422 rests on the table. The user then manually opens the battery cover 2 to remove the lithium battery 7 or dry cell battery 11 from the battery compartment 1.

[0092] After the user takes the lithium battery 7, they place the end of the lithium battery 7 without the magnetic strip on the base plate 412, with the lithium battery 7 positioned within the outer frame 411. Gently press the base plate 412 manually. As the lithium battery 7 presses down on the base plate 412, the base plate 412 begins to move downwards within the outer frame 411, compressing the telescopic rod 424 and the airbag 417. During this compression, the gas in the airbag 417 moves upwards through the vent 418 to the first channel 413 and the second channel 414, thus providing airflow to the bottom of the lithium battery 7. Simultaneously, during the downward press, the base plate 412 presses down on the second moving rod 416, which in turn moves the second outer ring 420 downwards, compressing the telescopic column 421. The telescopic column 421 transmits force to the base 422, promoting the adhesion and fixation of the second suction strip 423 below the base 422 to the tabletop.

[0093] After the user takes out the dry cell batteries 11, they place the two batteries 11 on the pads 415 of the two first channels 413 respectively, and gently press the base plate 412 manually. As the dry cell batteries 11 press down on the pads 415, the base plate 412 and the pads 415 begin to move downward in the outer frame 411, squeezing the telescopic rod 424 and the airbag 417. During the squeezing process, the gas in the airbag 417 moves upward through the vent 418 to the first channel 413 and the second channel 414, thereby supplying air to the bottom of the dry cell batteries 11. During the pressing process, the base plate 412 presses down on the second moving rod 416. The second moving rod 416 drives the second outer ring 420 to move downward, squeezing the telescopic column 421. The telescopic column 421 transmits the force to the base 422, promoting the second suction strip 423 under the base 422 to adhere and fix to the table.

[0094] This invention provides a dual-mode heterogeneous power management method compatible with both dry cell batteries and lithium batteries, comprising the following steps:

[0095] S1. When in use, the built-in battery pack 6 in the battery compartment 1 uses lithium battery 7. The Hall sensor 9 of the battery compartment 1 senses the magnet of the lithium battery 7 and identifies the power supply as 3.7V lithium battery 7.

[0096] S2. When the lithium battery 7 is low on power, connect the enclosure 3 to the battery compartment 1 and place the base 422 on the table.

[0097] S3. After removing the lithium battery 7, place it on the base plate 412 inside the placement box 404, and press the base plate 412 to trigger the airbag 417 to blow air.

[0098] S4. Place the dry cell battery 11 in the battery compartment 1. The power supply is identified as 3.0V dry cell battery 11.
