Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent door locks, and in particular relates to a double battery compartment structure for intelligent door locks. Background Art

[0002] Smart locks are improved on the basis of traditional mechanical locks. With the rapid development of smart lock technology, smart locks are becoming more and more automated and popular. A battery module needs to be installed in the smart lock to power the functional modules of the smart lock.

[0003] The existing smart door lock batteries are usually placed inside the door lock, that is, on the home side. This is because placing the battery on the home side is more convenient for users to replace and maintain, without the need to operate outdoors, which is also safer.

[0004] Existing smart door locks are usually powered by lithium batteries or dry batteries. In order to simplify the single-circuit design and reduce costs, lithium batteries are usually used in series in the circuit, while dry batteries are used by connecting a number of dry batteries in series in the circuit. When the battery is out of power after a certain period of use, the battery can only be replaced, which easily leads to the situation that the house cannot be opened due to a dead battery.

[0005] Therefore, dual batteries are used in smart door locks for power supply. Usually, in order to save space, the battery compartments are set in front and back to place the batteries. Therefore, the lengths of the two battery compartments set in the front and back need to maintain an appropriate ratio to ensure that the two batteries will not interfere with each other during storage and the batteries cannot be placed normally.

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-Figure 5As shown, a dual battery compartment structure for a smart door lock 1 includes a first battery compartment 21, a second battery compartment 22 and a second locking assembly 5 arranged at the lower part of the door lock 1; and also includes a second locking assembly 5, which is installed on the top of the second battery compartment 22 and is used to lock the battery 11 in the second battery compartment 22;

[0027] The first battery compartment 21 and the second battery compartment 22 are staggered in vertical arrangement, and the battery 11 installed in the first battery compartment 21 is located at the front end of the second locking assembly 5; the height of the first battery compartment 21 is lower than the height of the second battery compartment 22, and there is a height difference between the first battery compartment 21 and the second battery compartment 22 in the upward direction of the door lock 1. The straight-line distance from the bottom of the first battery compartment 21 to the top of the second battery compartment 22 is the placement distance of the battery 11 located in the second battery compartment 22, and the ratio of the height difference to the placement distance is 0.2:1; the staggered arrangement of the first battery compartment 21 and the second battery compartment 22 allows the two battery compartments to occupy different spaces in the vertical direction. This design can make full use of the space and make the device more compact. The battery 11 installed in the first battery compartment 21 is located at the front end of the second locking assembly 5. This means that when the battery 11 in the second battery compartment 22 is locked, the battery 11 in the first battery compartment 21 will not be disturbed. At the same time, this design also makes it convenient for the user to directly access and operate the first battery compartment 21 from the front. The proportional relationship between the placement distance of the second battery compartment 22 and the battery 11 ensures that there is enough space between the two battery compartments to install and remove the battery 11, while also ensuring the stability and compactness of the structure. In summary, the design of the first battery compartment 21 and the second battery compartment 22 being staggered up and down allows the two battery compartments to coexist in a limited space, and brings many benefits by optimizing space utilization, improving operational convenience, enhancing structural stability, and realizing modular design.

[0028] In one embodiment, the traditional screw fixing method requires the user to use a tool (such as a screwdriver) to rotate the screw to open or close the cover 4 of the battery compartment. This method is not only cumbersome to operate, but also increases the risk of damaging the door lock 1 due to improper use of tools. It also includes a first locking component 3 and a cover plate 4. The first battery compartment 21 is located on the outside of the second battery compartment 22. The first battery compartment 21 and the second battery compartment 22 are both used to install the battery 11. The first locking component 3 is installed at the bottom of the first battery compartment 21, and the cover plate 4 is installed at the front end of the first battery compartment 21. One end of the cover plate 4 is clamped on the door lock 1, and the other end of the first battery compartment 21 and the cover plate 4 are clamped at the bottom of the first battery compartment 21; when the battery 11 needs to be replaced, the user only needs to press a button to easily unlock the first locking component 3 and open the first cover plate 4, so as to check or replace the battery 11 in the battery compartment, and at the same time, the battery compartment is quickly locked through simple operations. The user does not need to use any tools and can complete the unlocking operation with only one hand, which greatly simplifies the operation process and avoids the cumbersome and inconvenient replacement of the battery 11 due to the use of tools such as screwdrivers, and even the risk of damage to the door lock 1 due to improper use of tools.

[0029] The first battery compartment 21 and the second battery compartment 22 are both provided with a power connector 12. The two power connectors 12 are arranged in parallel in the door lock 1 circuit. The two batteries 11 are connected in parallel to independently power the door lock 1. In the parallel circuit, the voltage between the batteries 11 is equal, and the current is distributed according to the capacity of the battery 11 and the requirements of the circuit. When powered on, the battery 11 is connected to the power connector 12 to power the door lock 1. After using the battery 11 for a long time, even if the battery 11 in one of the battery compartments is exhausted, the battery 11 in the other battery compartment can still continue to power the door lock 1, thereby ensuring the normal operation of the door lock 1.

[0030] In one embodiment, the first locking assembly 3 includes a positioning seat 31, a top cover 32, a top pin 33, a first spring 34 and an unlocking button 35; the positioning seat 31 is fixedly installed on the door lock 1, a sunken mounting groove 311 is provided in the middle of the positioning seat 31, the top pin 33 is provided in the middle of the upper side of the mounting groove 311, one end of the first spring 34 is fixed to the groove wall of the mounting groove 311, and the other end is connected to the unlocking button 35, the unlocking button 35 is slidably connected to the mounting groove 311, the top cover 32 is installed at the front end of the positioning seat 31, and the unlocking button 35 is abutted against the mounting groove 311; in the initial state, the first spring 34 will The unlock button 35 abuts against the lower part of the door lock 1 and contacts the corresponding locking part on the cover plate 4, thereby maintaining the locked state of the cover plate 4. At this time, the push pin 33 is compressed by the cover plate 4 and is in a compressed state; when the user needs to open the battery compartment to check or replace the battery 11, the unlock button 35 is pressed, and the unlock button 35 moves upward and compresses the first spring 34. As the unlock button 35 moves upward, the unlock button 35 no longer contacts the locking part of the cover plate 4. At the same time, because the cover plate 4 is not subjected to force, the push pin 33 pushes the cover plate 4 outward and can be opened, thereby allowing the user to check and replace the battery 11.

[0031] In one embodiment, the top pin 33 includes a fixing seat 331, a second spring 332 and a top column 333; the fixing seat 331 is fixedly installed in the installation groove 311, and the fixing seat 331 is a hollow cylindrical structure, the lower part of the top column 333 is sleeved in the second spring 332, and the second spring 332 is arranged in the fixing seat 331, and the top cover 32 is provided with a top groove 321, the top groove 321 and the fixing seat 331 are coaxial, and the top column 333 extends out of the top groove 321 and abuts against the cover plate 4; in the initial state, the cover plate 4 and the unlocking button The second spring 332 is in a compressed state, and the top post 333 is partially or completely located in the top groove 321 under the action of the spring.

The top groove 321 on the top cover 32 is coaxial with the fixing seat 331. The top post 333 can extend from the top groove 321 and abut against the cover plate 4 to push open the unlocked top cover 32. The top pin 33 of this structure is relatively simple and easy to maintain and replace. If the spring or the top post 333 is damaged, it can be quickly replaced to ensure the normal operation of the equipment.

[0032] In one embodiment, the second locking assembly 5 includes a second positioning plate 51, a pressure plate 52 and a marble 53; the marble 53 is installed on the door lock 1 and passes through the second positioning plate 51 and the pressure plate 52 to connect; the pressure plate 52 is slidably installed on the surface of the second positioning plate 51; the lower part of the pressure plate 52 is symmetrically provided with a pressing portion 521, and the pressing portion 521 is used to press the battery 11 installed in the second battery compartment 22; the setting of the marble 53 makes the pressure plate 52 more smooth when sliding with the second positioning plate 51, and the pressing Under the limiting action of the clamping portion 521, the plate 52 can slide in the same horizontal plane, which can enable the clamping effect of the clamping plate 52 on the battery 11. Secondly, under the action of the clamping portion 521 and the marble piece 53 in two different directions, the marble piece 53 acts upward on the clamping plate 52, and the clamping portion 521 acts downward on the clamping plate 52, which can ensure the clamping force of the clamping plate 52 on the battery 11 and ensure the stable position of the battery 11 in the second battery compartment 22 to prevent movement or loosening during transportation or use.
