Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery charging technology, and specifically relates to a battery charging compartment. Background Technology
[0002] Camera batteries, as the "heart" of photographic equipment, directly affect the shooting experience due to their charging efficiency, lifespan, and safety. Lithium-ion batteries have high energy density (150-250Wh / kg) and no memory effect, but overcharging / over-discharging must be avoided. Nickel-metal hydride batteries require periodic deep charging and discharging to maintain capacity, but have a higher self-discharge rate. The nominal voltage of lithium-ion batteries is typically 3.6-3.7V, with a full charge voltage of 4.2V. Nickel-metal hydride batteries are 1.2V, connected in series to adapt to the camera voltage. Camera and action camera batteries require a battery compartment during charging. Current battery compartments can arrange batteries to charge multiple batteries simultaneously. However, once the batteries are inside the compartment, the charger and batteries are interlocked, making it difficult to remove them quickly and easily after charging. The batteries need to be pried out from inside the compartment, which is inconvenient. Therefore, the inventor has proposed a battery charging compartment. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] This specific embodiment is a battery charging case, the structural diagram of which is shown below. Figure 1 , Figure 3 , Figure 4 As shown, the device includes a battery compartment 1, a charging cavity 2, and partition blocks 4. The battery compartment 1 contains charging pads 9. Multiple partition blocks 4 are spaced apart inside the battery compartment 1, dividing the interior of the battery compartment 1 into independent charging cavities 2. Each charging cavity 2 contains a charging pad 9. A top block 8 is installed at the bottom of the battery compartment 1. Multiple top blocks 8 are elastically positioned and installed inside the charging cavities 2. A first spring 10 is fixedly installed at the bottom of the top block 8. A card slot 7 for battery mounting is provided on the upper inner wall of the battery compartment 1. One, two, or more card slots 16 for accommodating cards used in electronic devices are provided on the outer periphery of the battery compartment 1. The card slots 16 are U-shaped card slots 16. The battery compartment 1 is a rectangular battery compartment, with two parallel U-shaped card slots 16 on the upper part of one or both outer sides of the rectangular battery compartment.
[0035] Because cards are thin and small, they are easily lost. The card slot 16 is designed to make it convenient for users to carry the cards. In addition, the concave card slot 16 makes it easy for users to slide the card corresponding to the concave part of the card slot 16 with their fingers, so that the card can be taken out of the card slot in time.
[0036] like Figure 2 and Figure 5 As shown, the charging chamber 2 has a removable cover 6 inside. The upper surface of the cover 6 has a locking mechanism 5, and the inner wall of the battery compartment 1 has a corresponding mounting groove 3 for the locking mechanism 5. The locking mechanism 5 includes a fixing block 12, an inner stop block 15, and a limiting block 11. The fixing block 12 has an inverted U-shaped structure and is fixedly installed on the upper surface of the cover 6. The limiting block 11 has an L-shaped structure and slides through the fixing block 12, with its end fitting into the mounting groove 3. Inner sliding grooves 14 are respectively provided on both sides of the limiting block 11 that penetrate into the fixing block 12. A second spring 13 is fixedly installed inside the inner sliding groove 14, and the end of the second spring 13 away from the inner sliding groove 14 is fixedly connected to the inner stop block 15. The inner stop block 15 is fixedly installed on the inner wall of the fixed block 12 near the end of the limiting block 11 that is slidably stretched.
[0037] Working principle: When in use, first remove the cover 6. Select the appropriate number of batteries to be charged and pull the corresponding limiting block 11. At this time, the second spring 13 moves closer to the inner stop block 15 and is compressed. The end of the limiting block 11 leaves the mounting groove 3, and the cover 6 can be removed from the inside of the charging cavity 2. Then, put the battery into the charging cavity 2. The buckle at the top of the battery engages with the buckle hole 7. The bottom surface of the battery is attached to the top block 8 and the top block 8 is pressed down. After the suction pad on the battery contacts the charging plate 9, the battery is completely fixed in the charging cavity 2. At this time, the battery compartment 1 can be connected to the power source, and the battery compartment 1 begins to supply power to the battery. The charging cavity 2, which is not being charged, is sealed by the cover 6 to prevent dust and impurities from falling in and to ensure the cleanliness of the inside of the charging cavity 2.
[0038] Once charging is complete, press the latch (elastic latch) on the battery. After the latch leaves the inside of the latch hole 7, the first spring 10 returns to its original position, and the top block 8 pops out from the bottom of the charging chamber 2, lifting the battery so that it can be easily removed.
[0039] After charging is complete, the cover 6 is installed. The elastic force of the second spring 13 drives the end of the limiting block 11 to be inserted into the mounting groove 3. The cover 6 protects the charging cavity 2, isolating the internal circuit components and preventing dust and impurities from falling in during carrying, thus improving the service life.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
