[0037] like Figure 1-6As shown, an embodiment of this utility model provides a battery cover structure, which includes a middle frame 1, a connecting plate 2, and a battery cover 3. The front side of the middle frame 1 has at least a first battery compartment 4 and a second battery compartment 5. The upper end of the first battery compartment 4 is provided with a first open groove 6, and the lower end of the second battery compartment 5 is provided with a second open groove 7. The back side of the middle frame 1 has a mounting base 8, which is located between the first open groove 6 and the second open groove 7. The connecting plate 2 is a circuit board, and a first connecting part 9 and a second connecting part 10 are formed on the connecting plate 2. The connecting plate 2 is mounted on the mounting base 8, the first connecting part 9 is embedded in the first open groove 6, and the second connecting part 10 is embedded in the second open groove 7. The battery cover 3 is detachably mounted on the front side of the middle frame 1 and closes the first battery compartment 4 and the second battery compartment 5. Two lithium batteries are secured by a battery cover 3, and the lithium battery connection board 2 (PCBA board) is also merged into one board, reducing the number of PCBA boards and corresponding connecting wires, improving the appearance quality of the product, and saving mold costs and individual part costs; moreover, the entire battery cover 3 is relatively simple to fix, and the user disassembly and assembly experience is good, which has broad market prospects.

[0038] Specifically, in this embodiment, the middle frame 1 is generally made of metal and requires high strength to prevent damage to the lock body from forced entry. The middle frame 1 is preferably made of alloy steel. Two battery compartments, a first battery compartment 4 and a second battery compartment 5, are stamped on the front side of the middle frame 1 using a stamping process. These battery compartments are used to assemble power supply batteries, preferably rechargeable lithium batteries. In this embodiment, the first battery compartment 4 is located below the second battery compartment 5. The first battery compartment 4 houses a first battery 11, and the second battery compartment 5 houses a second battery 12. Using two lithium batteries increases the battery capacity of the smart lock, meeting its long-term power supply needs, reducing the frequency of battery replacements or recharging, and improving the user experience. A first open slot 6 is provided at the upper end of the first battery compartment 4, and a second open slot 7 is provided at the lower end of the second battery compartment 5. The first open slot 6 and the second open slot 7 are used for connecting the two lithium batteries via a connecting plate 2.

[0039] More specifically, in this embodiment, a mounting base 8 is provided on the back side of the middle frame 1. The mounting base 8 is used to mount the connecting plate 2, which is a circuit board, i.e., a PCBA board. The mounting base 8 is located between the first open slot 6 and the second open slot 7, so that the connecting plate 2 can connect to the lithium batteries of the first battery compartment 4 and the second battery compartment 5. The two ends of the connecting plate 2 are respectively provided with a first connecting part 9 and a second connecting part 10. When installing the connecting plate 2, the first connecting part 9 is embedded in the first open slot 6 for installation, and the second connecting part 10 is embedded in the second open slot 7 for installation. The first connecting part 9 can be connected to the first battery 11 independently, and the second connecting part 10 can be connected to the second battery 12 independently.

[0040] Furthermore, in this embodiment, the first battery 11 is provided with a first power receiving part 13, and the second battery 12 is provided with a second power receiving part 14. When connecting the batteries, the first battery 11 is connected to the first connecting part 9, and the second battery 12 is connected to the second connecting part 10. That is, the first power receiving part 13 is inserted into the first power receiving part 13, and the second power receiving part 14 is inserted into the second connecting part 10. The first power receiving part 13 and the second power receiving part 14 are female connectors, and the first connecting part 9 and the second connecting part 10 are male connectors. The male connector is inserted into the female connector, thereby enabling the circuit to conduct and enabling the first battery 11 and the second battery 12 to power the smart lock. In the prior art, smart locks with two lithium batteries generally require two PCBA boards, resulting in a large number of parts and a higher overall cost. However, the battery cover structure of this embodiment only uses one connecting plate 2 to meet the power supply requirements, and the two batteries are directly connected through the connecting plate 2, eliminating the need for conventional connecting wires, reducing the number of parts, and thus further reducing the cost of the smart lock.

[0041] Furthermore, in this embodiment, the battery cover structure is equipped with a battery cover 3 to enclose the two battery compartments. The battery cover 3 is detachably installed on the front side of the middle frame 1 and simultaneously presses the two batteries together. The battery cover 3 uses a sliding cover method for locking and opening, which is stable, reliable, simple and practical. The two lithium batteries are fixed by a single battery cover 3, improving the product's appearance. Compared to the conventional technology of two covers, a single battery cover 3 saves on mold costs and reduces the overall cost of the battery cover 3.

[0042] Furthermore, in this embodiment, the front side of the middle frame 1 is provided with several sliding lock grooves 15, and the back side of the battery cover 3 is provided with several first latches 16 corresponding to the sliding lock grooves 15. The first latches 16 are engaged in the sliding lock grooves 15 for installation, and pushing the battery cover 3 causes the first latches 16 to be fastened to the sliding lock grooves 15. Specifically, six sliding lock grooves 15 are evenly and symmetrically arranged on the front side of the middle frame 1, and six first latches 16 are provided on the back side of the battery cover 3 corresponding to the sliding lock grooves 15. The first latches 16 are engaged in the sliding lock grooves for installation, and pushing the battery cover 3 upward causes the first latches 16 to fasten the sliding lock grooves 15, thereby locking the battery cover 3 onto the middle frame 1. When it is necessary to open the battery cover 3, pushing the battery cover 3 downward causes the first latches 16 to release the sliding lock grooves 15, thereby allowing the battery cover 3 to be lifted, making disassembly and assembly relatively convenient and quick. It should be noted that the number of sliding lock grooves 15 can be set according to actual needs, and the number of first latches 16 is usually the same as the number of sliding lock grooves 15. Preferably, in order to ensure that the upper surface of the battery cover 3 is flush with the surface of the middle frame 1 after installation, a recessed groove 17 is provided on the front side of the middle frame 1 to match the thickness of the battery cover 3. The sliding lock groove 15 is located on the recessed groove 17. This arrangement keeps the surface of the middle frame 1 flush with the surface of the battery cover 3, making the door lock more aesthetically pleasing. More specifically, a blocking part 18 is formed on one side of the sliding lock groove 15, and a first locking hook 19 is formed at the end of the first latch 16. The first locking hook 19 can be locked in the blocking part 18. When the battery cover 3 is pushed upward, the first locking hook 19 slides into the blocking part 18, and the end face of the first locking hook 19 abuts against the bottom of the blocking part 18, so that the first locking hook 19 locks the blocking part 18.

[0043] Furthermore, in this embodiment, a locking hole 20 is provided on the front side of the middle frame 1, and a locking groove 21 is provided on the back side of the middle frame 1. The locking hole 20 extends into the locking groove 21. A second latch 22 is provided at the upper end of the battery cover 3. The second latch 22 is inserted into the locking hole 20 for installation, and the battery cover 3 is pushed so that the second latch 22 is fastened to the locking groove 21. Specifically, the locking hole 20 is provided on the upper end face of the recessed groove 17. The locking hole 20 penetrates the middle frame 1 and extends upward. A locking groove 21 is provided on the back side of the middle frame 1 at the upper part of the second battery compartment 5, and the locking hole 20 extends into the locking groove 21. A second latch 22 is provided at the upper end of the battery cover 3. When installing the battery cover 3, the second latch 22 is inserted into the locking hole 20. The battery cover 3 is pushed upward, and the second latch 22 passes through the locking hole 20 and reaches the locking groove 21. The second latch 22 is fastened into the locking groove 21, so that the battery cover 3 can be further stably installed on the middle frame 1. More specifically, in order for the second latch 22 to engage with the locking groove 21, a second hook 23 is formed at the upper end of the second latch 22. When the battery cover 3 is pushed upward, the second hook 23 engages with the locking groove 21. When the battery cover 3 is pushed downward, the second hook 23 disengages from the locking groove 21, thereby allowing the battery cover 3 to be removed. Preferably, to facilitate the movement of the second hook 23 in and out of the locking groove 21, the surface of the second hook 23 has a rounded transition, and the front end of the locking groove 21 also has a rounded transition.

[0044] Furthermore, in this embodiment, the connecting plate 2 is provided with mounting holes 24, and mounting posts 25 are provided on both sides of the mounting base 8. Screws pass through the mounting holes 24 to securely connect the mounting posts 25. Specifically, to facilitate the installation of the connecting plate 2, two mounting holes 24 are provided at two opposite corners of the connecting plate 2, and two mounting posts 25 are also provided on both sides of the mounting base 8 corresponding to the mounting holes 24. When installing the connecting plate 2, screws pass through the mounting holes 24 to securely connect the mounting posts 25, thereby completing the installation of the connecting plate 2, which is convenient and quick.

[0045] Furthermore, in this embodiment, tension ribs 26 are provided on the side walls of both the first battery compartment 4 and the second battery compartment 5. The tension ribs 26 extend from the bottom of the compartment towards the opening and gradually decrease in thickness. Specifically, in order to ensure sufficient stability of the lithium battery when installed in the battery compartment, multiple tension ribs 26 are provided on the side walls of both the first battery compartment 4 and the second battery compartment 5. The tension ribs 26 extend from the bottom of the compartment towards the opening, and their thickness gradually decreases from the bottom to the opening, forming a accommodating space that is wide at the top and narrow at the bottom. When the lithium battery is installed in the battery compartment, as the lithium battery is pressed towards the bottom of the compartment, the lithium battery is pressed tighter and tighter under the action of the tension ribs 26, thereby ensuring that the lithium battery can be stably housed in the battery compartment.

[0046] Furthermore, this utility model also provides a smart door lock that uses the above-mentioned battery cover structure. The battery cover structure fixes two lithium batteries through a battery cover 3, and the lithium battery connecting plate 2 (PCBA board) is also merged into one plate, reducing the number of PCBA boards and corresponding connecting wires. This not only improves the appearance quality of the product, but also reduces the product cost. Moreover, the fixing method of the entire battery cover 3 is relatively simple, and the user disassembly and assembly experience is good, which has broad market prospects.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
