Description
Technical Field
[0001] The utility model relates to the technical field of intelligent door locks, and in particular to an anti-dismantling handle type electronic lock structure. Background Art
[0002] Handle-type smart locks, also known as semi-automatic smart door locks, are a new type of door lock that combines traditional door locks with intelligent technology. Their lock body is mechanical, primarily handle-type, and lacks electronic control, resulting in superior stability and durability. Most models can operate a floor hook and are relatively affordable. However, due to their low tamper resistance, handle-type smart locks are primarily used on interior doors and less frequently on entry doors.
[0003] Existing Figure 1 A handle-type smart lock shown in the figure includes a bottom shell 1, in which a clutch module 16, a motor 17, a control main board 10 and a battery pack 18 are arranged. A cover plate 2 is pressed on the bottom shell 1 by fixing bolts 19, so that the above components are accommodated in the bottom shell 1. In addition, a decorative plate 3 is fastened on the bottom shell 1, and the above bolts are covered by the decorative plate 3. However, the above-mentioned handle-type smart lock can be easily pried off the decorative plate 3 from the outside, and then the cover plate 2 can be easily removed by screwing the bolts, and finally the clutch pin of the clutch module 16 can be turned to unlock the lock outdoors. It can be seen that there is an urgent need for an anti-disassembly handle-type electronic lock structure that is difficult to open the bottom shell 1 from the outside, so as to broaden the application scenarios of the handle-type smart lock. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an anti-disassembly handle type electronic lock structure.
[0005] The purpose of this utility model is achieved through the following technical solutions:
[0006] A tamper-evident handle-type electronic lock structure comprises a bottom shell with an internal accommodating cavity, an upper cover for covering the accommodating cavity being provided on the bottom shell, the upper cover being covered over the bottom shell, and a buckle edge being constructed at the edge of the upper cover, the buckle edge being buckled with the bottom shell, thereby limiting the upper cover from detaching from one side of the bottom shell.
[0007] Preferably, buckle edges are constructed on all four edges of the upper cover.
[0008] Preferably, the buckle edge is formed by molding the upper cover.
[0009] Preferably, a handle function module is provided in the accommodating cavity, and the handle function module includes a lower shell and an upper shell that cooperate with each other, and an installation cavity is formed between the upper shell and the lower shell, and a clutch module, a motor and a control mainboard are provided in the installation cavity.

Detailed implementation manners
[0024] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.
[0025] As Figures 2 to 6 shown, a tamper-proof handle-type electronic lock structure includes a bottom shell 1 with an accommodation cavity internally constructed, and the components required for the electronic lock are installed in the accommodation cavity. In order to achieve the purpose of anti-tampering, an upper cover 4 for covering the accommodation cavity is provided on the bottom shell 1 in a covering form, and a buckling edge 5 buckling on the bottom shell 1 is constructed at the edge of the upper cover 4. It can be understood that when the handle-type electronic lock is installed on the door body, the upper cover 4 is opened to face the user side, and the buckling edge 5 is formed in the narrow space between the electronic lock and the door body. Therefore, for a door prying person, the upper cover 4 has a smooth surface on the outside of the electronic lock, and it is difficult to use conventional tools to enter the above-mentioned narrow space to damage the buckling edge 5, thereby reducing the possibility of this disclosure being maliciously disassembled.
[0026] For example, buckling edges 5 are provided at the four peripheral edges of the upper cover 4, and the buckling edges 5 can preferably be formed by stamping and closing the upper cover 4. That is to say, the buckling edge 5 and the upper cover 4 are integrally formed, so the buckling edge 5 is more difficult to be straightened under the action of conventional tools, and the upper cover 4 cannot be separated from the side away from the bottom shell 1.
[0027] In some embodiments, a handle function module 6 is provided in the accommodation cavity. For example, the handle function module 6 includes an upper shell and a lower shell 7 that cooperate with each other, and an installation cavity 9 is formed between the upper shell and the lower shell 7, and the components required for the electronic lock are installed in the installation cavity 9. Among them, the components required for the electronic lock may include a clutch module 16, a motor 17, and a control main board 10, and the clutch module 16 is a prior art, so it will not be described in detail in this disclosure. Preferably, the upper shell and the lower shell 7 can be locked by bolts.
[0028] For example, the lower shell 7 is constructed with a boss 13, which is provided with a communication hole 11 that connects to the mounting cavity 9. The bottom shell 1 is constructed with a through slot 12. The boss 13 and through slot 12 are adapted to have matching dimensions, that is, the boss 13 can be embedded in the through slot 12. The control motherboard 10 is adapted to be installed in a position opposite the communication hole 11. On the one hand, the boss 13 cooperates with the through slot 12 to define the installation position of the handle function module 6 within the accommodating cavity; on the other hand, external unlocking and locking signals can be smoothly communicated with the control motherboard 10 through the through slot 12 and the communication hole 11.
[0029] In a preferred example, a plurality of communication holes 11 are provided, and they may be distributed in a honeycomb shape, for example, so as to further increase the smoothness of communication.
[0030] In some embodiments, a tooth-like structure 14 is provided on one of the inner wall of the upper cover 4 and the outer wall of the bottom shell 1, and a claw-like structure 15 is provided on the other of the inner wall of the upper cover 4 and the outer wall of the bottom shell 1. For example, the outer wall of the bottom shell 1 has a tooth-like structure 14, and the inner wall of the upper cover 4 has a corresponding claw-like structure 15. When the upper cover 4 is wrapped around the bottom shell 1, the claw-like structure 15 engages with the tooth-like structure 14, thereby preventing the upper cover 4 from slipping away from the side of the bottom shell 1, thereby further increasing the difficulty of malicious tampering with the electronic lock. The coupling method of the claw-like structure 15 and the tooth-like structure 14 can refer to the structure of a cable tie in the prior art. For example, the claw-like structure 15 has a certain degree of elasticity, so that it can continuously engage with different positions of the tooth-like structure 14 as the upper cover 4 is buckled relative to the bottom shell 1.
[0031] The electronic lock disclosed herein may have the following unlocking and closing processes:
[0032] After pairing with the smart handle through the mobile phone Bluetooth, the mobile phone's opening signal is transmitted to the control motherboard 10 through the communication port 11. The control motherboard 10 sends an action instruction to the motor 17. The motor 17 pushes the clutch ejector pin forward to insert into the clutch square steel connecting shaft. The square steel connecting shaft can drive the square steel to unlock; after the preset unlocking time is over, the motor 17 retreats, and the clutch ejector pin is pulled out of the clutch square steel connecting shaft limit groove under the action of the ejector pin reset spring force. At this time, the square steel connecting shaft is in a free state, and the square steel fails, that is, the door lock cannot be opened.
[0033] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
