Utility Model Content

[0005] The purpose of this invention is to provide an emergency power supply device for wireless charging of smart locks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An emergency power supply device for wireless charging of a smart lock includes an outer lock body, the bottom of which has an installation groove, a pair of connecting posts at the bottom of the installation groove, and an emergency power supply structure inserted into the installation groove.

[0008] The emergency power supply structure includes a bottom shell, a top cover fixed to the top of the bottom shell, a pair of contact metal posts installed at the tail end of the top cover, and a dial plate.

[0009] The bottom shell is inserted into the mounting slot. The bottom shell has a mounting cavity for placing a spare lithium battery and a wireless charging module. The bottom shell has a pair of insertion holes at its tail end. The bottom shell has two grooves at the tail edge of its top surface. The two grooves are connected to the two insertion holes respectively. The bottom shell also has a sliding groove on its top surface. The sliding groove is connected to the two insertion holes.

[0010] A movable groove is provided at the tail edge of the bottom surface of the top cover, and a push groove is provided at the bottom of the movable groove;

[0011] A baffle is fixed on the outer surface of the contact metal post, and a spring is fitted around the bottom of the contact metal post at the bottom of the baffle. A metal sheet is fixed to the bottom end of the spring.

[0012] The lever is fitted inside the movable groove and slidably connected to the top cover. A pair of baffles are fixed at the bottom end of the lever, and the baffles extend into the sliding groove. When the lever moves to the leftmost end of the movable groove, the lever drives the two baffles to move to the head position of the contact metal column.

[0013] Preferably, the connecting post is made of metal, and the position of the connecting post corresponds to the position of the socket. When the emergency power supply structure is inserted into the mounting groove, the connecting post is inserted into the socket.

[0014] In this setup, the metal connecting post is precisely inserted into the socket through precise alignment with the socket.

[0015] Preferably, slots are provided on both the left and right edges of the bottom of the mounting groove, and protruding insertion strips are provided on the bottom edges of both the left and right surfaces of the bottom shell, the insertion strips being able to be inserted into the slots;

[0016] In this setup, the emergency power supply structure is installed in the mounting slot by inserting a connector strip into the slot. This allows for easy insertion and removal of the emergency power supply structure within the outer lock body, achieving the purpose of installing and removing the emergency power supply structure from the outer lock body.

[0017] Preferably, a plurality of positioning magnetic posts are embedded at the first edge of the bottom surface of the mounting groove, and a plurality of magnetic metal blocks are embedded at the first edge of the bottom surface of the bottom shell. When the emergency power supply structure is inserted into the mounting groove, the positions of the magnetic metal blocks and the positions of the positioning magnetic posts correspond one-to-one.

[0018] In this setup, the positioning magnetic post and magnetic metal block are used to position the emergency power supply structure onto the outer lock body when it is inserted into the emergency power supply structure, preventing the structure from falling off.

[0019] Preferably, a connecting hole is provided between the socket and the groove, and the head of the contact metal post has a smooth arc-shaped spherical surface, and the head of the contact metal post extends into the socket from the connecting hole;

[0020] This configuration ensures that when the emergency power supply structure is installed in the external lock body, the head of the contact metal post can make contact with the connecting post, achieving an electrical connection.

[0021] Preferably, the groove is open, and the width of the groove is smaller than the width of the dial plate;

[0022] Preferably, the top surface of the dial plate is provided with a plurality of longitudinally oriented protrusions, the length of which is less than the width of the dial groove.

[0023] In both of these settings, the slot, which is smaller than the width of the lever, prevents the lever from coming out of the top cover. The slot design also makes it convenient for people to move the lever by turning the protrusion.

[0024] Preferably, when the dial is moved to the rightmost end of the movable slot, the baffle moves away from the head of the contact metal post, and at this time the head of the contact metal post comes into contact with the connecting post.

[0025] In this configuration, the electrical connection between the contact metal post and the connecting post is blocked by the baffle, cutting off the power supply to the emergency power supply structure and preventing the loss of power from the emergency power supply structure.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. The emergency power supply device for wireless charging of this smart lock improves charging convenience and efficiency by setting up an emergency power supply structure that can be detached from the outer lock body. Through the matching of the bottom shell's plug strip with the mounting slot, the alignment and adsorption of the positioning magnetic column and the magnetic metal block, and the precise docking of the connecting column and the socket, the emergency power supply structure is ensured to be firmly installed on the outer lock body and can be quickly plugged in and out. When the outer lock body itself is low on power, the user can use the emergency power supply structure to provide emergency power to the outer lock body, ensuring that the smart lock can be opened normally in emergency situations.

[0028] 2. The contact metal post, combined with a spring and metal plate, is linked with the lever and baffle. The connection between the contact metal post and the connecting post can be controlled by moving the lever to move the baffle. When the lever is moved to block the baffle between the contact metal post and the connecting post, the emergency power supply structure is electrically disconnected from the outer lock body to prevent the power in the emergency power supply structure from gradually being lost, so as to facilitate emergency use.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0042] For emergency power supply devices for wireless charging of smart locks, please refer to [link / reference]. Figures 1-9The system includes an outer lock body 1, with a mounting groove 11 at its bottom. A pair of connecting posts 12 are located at the bottom of the mounting groove 11. An emergency power supply structure 2 is inserted into the mounting groove 11. The emergency power supply structure 2 contains a backup lithium battery and a wireless charging module. The backup lithium battery provides emergency power to the outer lock body 1, and the wireless charging module is the charging structure for the backup lithium battery, enabling it to be charged wirelessly and increasing the convenience of charging. The emergency power supply structure 2 includes a bottom shell 21, a top cover 22 fixed to the top of the bottom shell 21, a pair of contact metal posts 23 mounted at the tail end of the top cover 22, and a lever 24. The two contact metal posts 23 are electrically connected to the positive and negative terminals of the power supply of the electronic lock body itself inside the outer lock body 1 via wires.

[0043] like Figure 3 , Figure 4 ,and Figure 6 As shown, in this utility model, slots 111 are provided on both the left and right edges of the bottom of the mounting groove 11, and protruding insertion strips 212 are provided on the bottom edges of both the left and right surfaces of the bottom shell 21. The insertion strips 212 can be inserted into the slots 111. By aligning the insertion strips 212 with the slots 111, the bottom shell 21 can be inserted into the mounting groove 11, thus achieving the purpose of installing the emergency power supply structure 2. The cooperation between the slots 111 and the insertion strips 212 enables the emergency power supply structure 2 to be quickly positioned and securely installed, preventing it from loosening or falling off during use.

[0044] like Figures 3-6 As shown, specifically, several positioning magnetic posts 13 are embedded at the first edge of the bottom surface of the mounting groove 11, and several magnetic metal blocks 216 are embedded at the first edge of the bottom surface of the bottom shell 21. When the emergency power supply structure 2 is inserted into the mounting groove 11, the positions of the magnetic metal blocks 216 and the positioning magnetic posts 13 correspond one-to-one. Under the action of magnetism, when the bottom shell 21 is inserted into the mounting groove 11, the positioning magnetic posts 13 and the magnetic metal blocks 216 can be aligned to attract each other, assisting in the precise installation of the emergency power supply structure 2 and enhancing the connection stability between the emergency power supply structure 2 and the outer lock body 1.

[0045] like Figure 2 , Figure 3 and Figure 6 As shown, the bottom shell 21 is further provided with a mounting cavity 211 for placing a backup lithium battery and a wireless charging module. The tail end of the bottom shell 21 is provided with a pair of sockets 213. The connecting post 12 is made of metal material. The position of the connecting post 12 corresponds to the position of the socket 213. When the emergency power supply structure 2 is inserted into the mounting groove 11, the connecting post 12 can be inserted into the socket 213.

[0046] like Figure 6 and Figure 8As shown, further, two grooves 214 are provided at the tail edge of the top surface of the bottom shell 21. The two grooves 214 are respectively connected to two sockets 213. The contact metal post 23 is set in the groove 214. A baffle 231 is fixed on the outer surface of the contact metal post 23. A spring 232 is provided on the bottom of the contact metal post 23 of the baffle 231. A metal piece 233 is fixed at the bottom end of the spring 232. The metal piece 233 abuts against the front wall of the groove 214. The two metal pieces 233 are electrically connected to the positive and negative terminals of the spare lithium battery by wires. A connecting hole 2131 is provided between the socket 213 and the groove 214. The head of the contact metal post 23 has a smooth arc-shaped spherical surface. The head of the contact metal post 23 extends into the socket 213 from the connecting hole 2131. When the emergency power supply structure 2 is fully installed into the mounting groove 11, the head of the contact metal post 23 contacts the connecting post 12, so that the backup lithium battery and the power supply of the outer lock body 1 are connected in parallel. The backup lithium battery can be used as a power source to power the unlocking when the power supply of the outer lock body 1 is exhausted.

[0047] like Figure 6 and Figure 7 As shown, a movable groove 221 is provided at the tail edge of the bottom surface of the top cover 22. The lever 24 is fitted into the movable groove 221 and slidably connected to the top cover 22. A sliding groove 215 is also provided on the top surface of the bottom shell 21, and the sliding groove 215 is connected to the two insertion holes 213. A pair of baffles 241 are fixed at the bottom end of the lever 24. The baffles 241 extend into the sliding groove 215. When the lever 24 moves to the leftmost end of the movable groove 221, the lever 24 drives the two baffles 241 to move to the head position of the contact metal post 23. When the lever 24 is moved to the rightmost end of the movable groove 221, the baffles 241 move away from the head of the contact metal post 23. At this time, the head of the contact metal post 23 contacts the connecting post 12. The sliding linkage design of the toggle 24 and the baffle 241 provides a convenient way to control the circuit on and off, making it easy for users to operate and manage emergency power supply, and reducing the power loss of emergency power supply structure 2 by disconnecting the power supply of emergency power supply structure 2.

[0048] like Figure 7 and Figure 9 As shown, a through groove 222 is provided at the bottom of the movable groove 221. The width of the through groove 222 is smaller than the width of the lever 24, which prevents the lever 24 from coming out of the through groove 222 and keeps the lever 24 confined in the movable groove 221. Several longitudinally oriented protrusions 242 are provided on the top surface of the lever 24. The length of the protrusions 242 is smaller than the width of the through groove 222. The design of the protrusions 242 improves the operating feel and positioning accuracy of the lever 24, making it easier for people to operate the lever 24.

[0049] It is worth noting that the backup lithium battery and wireless charging module involved in this utility model are existing conventional technologies, and will not be described in detail here.

[0050] In this embodiment, when an emergency power supply is needed for the wireless charging emergency power supply device of the smart lock, the user first moves the lever 24, causing it to slide from the leftmost end to the rightmost end within the movable slot 221. The lever 24 drives the baffle 241 to move within the sliding slot 215. Then, when the lever 24 moves to the rightmost end, the baffle 241 moves away from the head of the contact metal post 23. The contact metal post 23 pops out under the action of the spring 232, causing the head of the contact metal post 23 to contact the connecting post 12. This electrically connects the backup lithium battery to the power input terminal of the electronic lock body inside the outer lock body 1, providing power to the smart unlocking mechanism and enabling emergency unlocking. Finally, in daily use, if emergency power is not needed, the lever 24 is moved to the left to the leftmost end of the movable slot 221, causing the baffle 241 to move to the position of the head of the contact metal post 23. This prevents the contact metal post 23 from contacting the connecting post 12, disconnecting the circuit connection between the emergency power supply structure 2 and the outer lock body 1, and preventing the backup lithium battery from losing power.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
