[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figures 1-6 This utility model discloses a convenient snap-lock digital battery charger, including a charger housing 1 and a battery 8. A middle shell 3 is installed inside the charger housing 1. The top of the middle shell 3 has a battery compartment 4 for placing the battery 8. A mounting position 5 is provided on one inner wall of the battery compartment 4. A snap-lock 6 for fixing the battery 8 is installed in the mounting position 5. A spring 7 is installed on the bottom inner wall of the battery compartment 4, with its top contacting the bottom of the battery 8. When the snap-lock 6 is not locking the battery 8, the spring 7 pushes the battery 8 upwards. When the battery 8 is inserted into the battery compartment 4, the battery 8 can compress the spring 7. When the spring 7 is fully compressed, the snap-lock 6 can lock the battery 8 from above, thus fixing the battery 8 in the battery compartment 4 for charging. To remove the battery 8, simply pull the top of the snap-lock 6 to engage the locking mechanism, and the battery 8 will be lifted to a suitable height by the reset spring 7, allowing for easy removal of the battery 8.

[0025] A display screen 17 is mounted on one side of the charger housing 1.

[0026] The charger housing 1 has a main board 18 installed on the bottom inner wall, located below the middle shell 3. The main board 18 is electrically connected to the display screen 17. The bottom of the middle shell 3 has a support column that is in contact with the main board 18.

[0027] The bottom inner wall of the battery compartment 4 is equipped with an electrode assembly 19 that contacts the battery 8. When the battery 8 is placed in the battery compartment 4 and the spring 7 is compressed into place, the bottom of the battery 8 contacts the electrode assembly 19. The electrode assembly 19 includes a positive electrode spring and a negative electrode spring.

[0028] A button is provided on one side of the charger housing 1, and a power interface is provided on the side away from the button.

[0029] Specifically, the spring clip 6 includes a mounting block 9, a spring arm 10, and a limiting block 11. The mounting block 9 is integrally connected to the L-shaped spring arm 10, and the top side of the spring arm 10 is integrally connected to the limiting block 11 for pressing the top of the battery 8.

[0030] The spring clip 6 also includes a pressing block 12, and the pressing block 12 is integrally connected to the side of the top of the spring arm 10 away from the limiting block 11.

[0031] In this embodiment, the mounting block 9 is provided with mounting holes, and the inner wall of the mounting position 5 can be provided with screw holes. The spring clip 6 is fixed in the mounting position 5 by a screw that passes through the mounting hole and is threaded to the middle shell 3. One side surface of the middle shell 3 is provided with a clearance hole for installing screws so that screws can be installed by using tools such as screwdrivers.

[0032] The charger housing 1 consists of a front cover and a rear cover. The four corners of one side of the rear cover are fixedly connected to mounting posts with screw holes, while the four corners of one side of the front cover are provided with mounting holes that mate with the mounting posts. The front cover and the rear cover are connected by screws that pass through the mounting holes and are threaded into the screw holes on the mounting posts.

[0033] A through slot is provided on one side of the front cover to mate with the clearance hole, and the display screen 17 is mounted on the front cover of the charger housing 1 and covers this through slot.

[0034] The spring clip 6 is installed in the mounting position 5. When the battery 8 is inserted into the mounting position 5, the spring 7 is compressed to the position and the bottom of the battery 8 contacts the electrode assembly 19. The limiting block 11 on the spring clip 6 can fix the battery from above, so that the battery 8 can be charged. When the battery 8 is removed, the pressing block 12 on the spring clip 6 is gently pulled, so that the spring arm 10 deforms and the limiting block 11 releases the limiting of the battery 8. The spring 7 springs up and can lift the battery 8 to a suitable height, so that the battery 8 can be easily removed.

[0035] Specifically, the charger housing 1 is rotatably connected to a flip cover 2 that can cover the battery compartment 4.

[0036] A lower mounting groove 13 is provided on one side of the middle shell 3, and a lower magnet 14 is installed in the lower mounting groove 13. An upper magnet 15 is installed on the flip cover 2 and is magnetically connected to the lower magnet 14.

[0037] A protrusion 20 is integrally connected to one side of the flip cover 2, and a groove 21 is provided on the top side of the charger housing 1, through which the protrusion 20 can pass.

[0038] In this embodiment, a silicone component is connected to the bottom of the flip cover 2. An assembly groove is opened on the silicone component, and the upper magnet 15 is assembled in this assembly groove. An SD card slot for installing an SD card is provided on the side of the silicone component away from the flip cover 2.

[0039] When the flip cover 2 covers the battery compartment 4, the upper magnet 15 and the lower magnet 14 are magnetically connected, and the protrusion 20 passes through the groove 21, so that the flip cover 2 can maintain a relatively stable state. When it is necessary to open the flip cover 2, the flip cover 2 can be easily flipped over by operating the protrusion 20 passing through the groove 21 to expose the battery compartment 4, so that the battery 8 can be taken out and installed.

[0040] Specifically, silicone anti-slip pads 16 are provided on both sides of the bottom of the charger housing 1.

[0041] In this embodiment, when the digital battery charger is placed on a flat surface such as a table, the silicone anti-slip pad 16 can increase the friction between the bottom of the digital battery charger and the surface on which it is placed.

[0042] In summary, this convenient snap-lock digital battery charger allows the battery 8 to compress the spring 7 when it is inserted into the battery compartment 4. When the spring 7 is fully compressed, the snap 6 can limit the battery 8 from above, thus securing the battery 8 within the battery compartment 4 for charging. When removing the battery 8, simply pull the top of the snap 6 to engage the limiting mechanism, and the battery 8 will be lifted to a suitable height by the reset spring 7, allowing for easy removal of the battery 8.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
