[0002] The optimal antenna position is at a mid-height on the front door panel. However, the PCB in smart locks is typically located on the rear handle, which is far from the optimal antenna position. Furthermore, there are numerous smart lock models, and the installation environment in users' homes is complex. These factors make on-site wiring management difficult, easily leading to non-standard installations that affect signal transmission quality. Utility Model Content

[0003] In view of this, this utility model provides a smart lock antenna structure to address the issues that the optimal antenna position is at a mid-height on the front door panel, while the PCB in smart locks is generally located on the rear handle, which is far from the optimal antenna position. Furthermore, there are many different smart lock models, and the installation environment in users' homes is complex. These factors make on-site wiring management difficult and prone to non-standard construction, affecting signal transmission quality.

[0004] In a first aspect, this utility model provides a smart lock antenna structure, comprising:

[0005] A packaging shell, wherein the packaging shell has a front cavity and a rear cavity, and a front fixing plate is installed in the front cavity;

[0006] PCB board, the PCB board being installed within the rear cavity;

[0007] A fixing component, wherein one end of the fixing member is connected to the PCB board and the other end is connected to the front fixing plate;

[0008] An antenna structure, wherein the signal transmission end of the antenna structure is installed between the fixing component and the front fixing plate.

[0009] Beneficial Effects: This application achieves signal connection between the PCB board and the antenna structure by setting a fixed component. The fixed component has a certain length, enabling the PCB board in the rear cavity to transmit and receive signals from the antenna structure in the front cavity. The structure is simple and effective, optimizes intermediate frequency characteristics, and ensures signal transmission quality. It also avoids the need for flying wires, ensuring quality even in cases of non-standard construction. It does not require changing the positions of the PCB board and antenna in existing technologies. By setting a fixed component in the PCB board and antenna structure, it fully considers the door lock installation process and does not add difficulties to factory processing and on-site construction.

[0010] In one alternative implementation, the fixing component includes:

[0011] The first rod body has an external thread on its outer surface and a first blocking part at one end of the first rod body.

[0012] The second rod body has a second blocking part at one end away from the first blocking part, and an internal thread groove is opened in the second rod body facing the opening of the first rod body.

[0013] The first rod can be screwed into the internal threaded groove to fix the first rod and the second rod.

[0014] Beneficial effects: The first rod, the first blocking part, the second rod, and the second blocking part are all made of metal, which is a conductive medium. The first rod and the second rod are connected by a thread, which is an effective connection method. The transmission of electrical signals is better. Of course, the top of the external thread and the internal thread can also be set as a curved surface to increase the contact area, improve the signal transmission speed, and improve the signal radiation intensity.

[0015] In one alternative implementation, the PCB board includes:

[0016] The PCB board body has mounting through holes.

[0017] A axial contact is disposed on the side of the PCB board body near the first blocking part;

[0018] The first rod is inserted into the mounting through hole so that the first blocking part abuts against the surface of the shaft contact point, and the PCB board is signal connected to the fixing component.

[0019] In one alternative embodiment, the antenna structure includes an antenna body and a connecting assembly, wherein the antenna body is installed in the front cavity, one end of the connecting assembly is connected to the antenna body, and the other end is installed on a second rod.

[0020] Beneficial effects: The end of the first rod furthest from the first blocking part faces the front cavity. This end passes through the annular central contact hole and the mounting through hole, and moves towards the front fixing plate. The mounting ring is fitted onto the second rod, with the end of the second rod furthest from the second blocking part facing the rear cavity. It passes through the front fixing plate and moves towards the first rod until the first rod is inserted into the internal thread groove of the second rod. With relative rotation between the two, the first rod is screwed into the internal thread groove, and the distance between the first and second blocking parts gradually decreases until the first blocking part abuts against the central contact, and the second blocking part presses the mounting ring against the front fixing plate, completing the installation. Through this installation method, the first blocking part abuts against the surface of the central contact, and the second blocking part presses the mounting ring against the front fixing plate, using a fixing assembly to achieve signal connection between the PCB board and the antenna structure. The structure is simple, enabling the PCB board in the rear cavity to transmit and receive signals from the antenna structure in the front cavity. The structure is simple and effective, and optimizes the intermediate frequency characteristics, ensuring signal transmission quality. Furthermore, it avoids the use of fly wires, ensuring quality even in cases of non-standard construction. It eliminates the need to alter the positions of the PCB board and antenna in existing technologies; by incorporating a fixing component within the PCB board and antenna structure, it fully considers the door lock installation process, without adding difficulties to factory processing or on-site construction.

[0021] In one alternative embodiment, the diameter of the mounting through hole is greater than or equal to the outer diameter of the first rod body and less than the outer diameter of the first blocking portion.

[0022] In one optional embodiment, the axial contact is configured as an annular shape, and the axial contact is coaxially arranged with the mounting through hole;

[0023] The inner diameter of the axial contact is greater than or equal to the outer diameter of the first rod body, and less than the outer diameter of the first blocking part.

[0024] Beneficial effects: The diameter of the mounting through hole is greater than or equal to the outer diameter of the first rod body and less than the outer diameter of the first blocking part. The inner diameter of the shaft contact is greater than or equal to the outer diameter of the first rod body and less than the outer diameter of the first blocking part. This ensures that the first rod body can be smoothly inserted into the shaft contact and the through hole. The first blocking part limits the shaft contact and the PCB board, preventing the shaft contact and the PCB board from falling off the first rod body.

[0025] In one alternative implementation, at least two connecting components are provided.

[0026] Beneficial effects: By using two connecting components, the contact area between the fixed component and the antenna structure is increased, thereby improving signal transmission speed and signal radiation intensity. Furthermore, even if one connecting component fails (e.g., breaks), the other component can still function normally, reducing the overall failure rate of the device.

[0027] In one alternative embodiment, the connection assembly includes: a connecting wire and a mounting ring, one end of the connecting wire being connected to the antenna and the other end being fixedly connected to the mounting ring;

[0028] The mounting ring is adapted to be fitted onto the second rod between the second blocking portion and the front fixing plate.

[0029] Beneficial effects: The connection between the antenna body, connecting wires, and mounting ring is soldered, but other methods can also be used, as long as the connection is stable and the signal transmission between the three components is not affected. This antenna structure is robust, improving its lifespan.

[0030] In one alternative embodiment, the inner diameter of the mounting ring is greater than or equal to the outer diameter of the second rod, and less than the outer diameter of the second blocking portion.

[0031] Beneficial effects: The inner diameter of the mounting ring is greater than or equal to the outer diameter of the second rod, and less than the outer diameter of the second blocking part. This ensures that the second rod can be smoothly inserted into the mounting ring, and the second blocking part limits the mounting ring, preventing it from falling off the second rod.

[0032] In one alternative implementation, the mounting ring is made of a highly conductive metal.

[0033] Beneficial effects: The mounting ring is made of highly conductive metals, such as copper and aluminum. Its low resistance and high frequency characteristics can significantly reduce signal loss, making it suitable for high-frequency signal transmission. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The optimal antenna placement is at a mid-height position on the front door panel. In smart locks, the PCB is typically located on the rear handle, which is far from the optimal antenna position. Furthermore, the wide variety of smart lock models and the complex installation environments in users' homes make on-site wiring management difficult, increasing the risk of substandard installation. Additionally, the numerous components and complex installation procedures of smart locks on-site make low-quality wiring through holes and even unexplained tangling highly likely, severely impacting wireless signal transmission.

[0046] To solve the above technical problems, the following will be combined with... Figures 1 to 4 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, an intelligent lock antenna structure is provided, comprising: a package housing, a PCB board 1, a fixing component 2, and an antenna structure 3.

[0048] like Figures 1 to 4As shown, the encapsulation housing has a front cavity and a rear cavity. The front cavity is close to the unlocking panel, and the rear cavity is close to the battery compartment. The PCB board 1 is fixedly installed in the rear cavity and can be connected to the encapsulation housing by screws or bolts. A front fixing plate 4 is installed in the front cavity and can be connected to the encapsulation housing by screws or bolts. In this embodiment, a fixing component 2 is designed. One end of the fixing component 2 is connected to the PCB board 1, and the other end is connected to the front fixing plate 4. The signal transmission end of the antenna structure 3 is installed between the fixing component 2 and the front fixing plate 4, so that the signal transmission end of the PCB board 1 and the antenna structure 3 are connected. This application realizes the signal connection between the PCB board 1 and the antenna structure 3 by setting a fixing component 2. The fixing component 2 has a certain length, realizing the transmission and reception of signals from the PCB board 1 in the rear cavity to the antenna structure 3 in the front cavity. The structure is simple and effective, and optimizes the intermediate frequency characteristics, ensuring the signal transmission quality. It also avoids flying wires and can guarantee quality even in the case of non-standard construction.

[0049] This embodiment does not require changing the positions of the PCB board 1 and the antenna in the prior art. By setting a fixed component 2 in the PCB board 1 and the antenna structure 3, the signal transmission and reception are realized. It fully considers the door lock installation process and does not add difficulties to factory processing and on-site construction.

[0050] In one embodiment, such as Figure 1 and Figure 2 As shown, the fixing assembly 2 includes: a first rod 21, a first blocking part 22, a second rod 23, and a second blocking part 24. The first rod 21 is cylindrical in shape, with external threads on its outer surface. The first blocking part 22 is located at one end of the first rod 21, and its outer diameter is larger than that of the first rod 21. The second rod 23 is also cylindrical in shape, and it has an internally threaded groove opening to one side. The internally threaded groove is coaxial with the second rod 23 and matches the external thread of the first rod 21. The second blocking part 24 is located at the end of the second rod 23 furthest from the opening of the internally threaded groove, and its outer diameter is larger than that of the second rod 23.

[0051] The first rod 21, the first blocking part 22, the second rod 23, and the second blocking part 24 are all made of metal and are conductive media. The first rod 21 and the second rod 23 are connected by a thread, which is an effective connection method and the transmission of electrical signals is better. Of course, the top of the external thread and the internal thread can also be set as a curved surface to increase the contact surface, improve the signal transmission speed, and improve the signal radiation intensity.

[0052] like Figure 1 and Figure 3As shown, the PCB board 1 includes: a PCB board body 11 and a spindle contact 12. The PCB board body 11 has a mounting through hole 111. The spindle contact 12 is annular and coaxially arranged with the mounting through hole 111. When opening the mounting through hole 111 and manufacturing the spindle contact 12, it is necessary to ensure that the diameter of the mounting through hole 111 is greater than or equal to the outer diameter of the first rod 21 and less than the outer diameter of the first blocking part 22, and the inner diameter of the spindle contact 12 is greater than or equal to the outer diameter of the first rod 21 and less than the outer diameter of the first blocking part 22. This ensures that the first rod 21 can be smoothly inserted into the spindle contact 12 and the through hole, and that the first blocking part 22 limits the spindle contact 12 and the PCB board 1 to prevent the spindle contact 12 and the PCB board 1 from falling off the first rod 21.

[0053] like Figure 1 and Figure 4 As shown, the antenna structure 3 includes an antenna body 31 and a connecting component 32. The antenna body 31 is installed in the front cavity. There are two connecting components 32. Taking one of the connecting components 32 as an example, its specific structure is explained. The connecting component 32 includes a connecting line 321 and a mounting ring 322. One end of the connecting line 321 is connected to the antenna, and the other end is fixedly connected to the mounting ring 322. The mounting ring 322 is adapted to be sleeved on the second rod 23 between the second blocking part 24 and the front fixing plate 4.

[0054] The antenna body 31, connecting wire 321, and mounting ring 322 are connected by welding, but other methods can also be used, as long as the connection is stable and the signal transmission between the three is not affected. This antenna structure 3 has a robust structure, which improves the service life of the antenna structure 3.

[0055] By setting two connecting components 32, the contact area between the fixing component 2 and the antenna structure 3 is increased, thereby improving the signal transmission speed and signal radiation intensity. Furthermore, even if one connecting component 32 fails (e.g., breaks), the other connecting component 32 can still function normally, reducing the overall failure rate of the device.

[0056] like Figure 1 As shown, the inner diameter of the mounting ring 322 is greater than or equal to the outer diameter of the second rod 23, and less than the outer diameter of the second blocking part 24. This ensures that the second rod 23 can be smoothly inserted into the mounting ring 322, and the second blocking part 24 limits the mounting ring 322 to prevent it from falling off the second rod 23.

[0057] Since the PCB board 1 and the front fixing plate 4 are fixed in the rear cavity and the front cavity respectively, during installation, the end of the first rod 21 away from the first blocking part 22 faces the front cavity, and the end of the first rod 21 away from the first blocking part 22 passes through the central hole of the annular shaft contact 12 and the mounting through hole 111, and moves toward the front fixing plate 4; the mounting ring 322 is sleeved on the second rod 23, and the end of the second rod 23 away from the second blocking part 24 faces the rear cavity, passes through the front fixing plate 4 and moves toward the first rod 21 until the first rod 21 is inserted into the internal thread groove of the second rod 23. With the relative rotation between the two, the first rod 21 is screwed into the internal thread groove, and the distance between the first blocking part 22 and the second blocking part 24 gradually approaches until the first blocking part 22 abuts against the shaft contact 12, and the second blocking part 24 presses the mounting ring 322 against the front fixing plate 4, and the installation is completed.

[0058] With the above installation method, the first blocking part 22 abuts against the surface of the shaft contact 12, and the second blocking part 24 presses the mounting ring 322 against the front fixing plate 4, thereby realizing the signal connection between the PCB board 1 and the antenna structure 3 by using the fixing component 2.

[0059] In one embodiment, the mounting ring 322 is made of a highly conductive metal, such as copper or aluminum, whose low resistance and high-frequency characteristics can significantly reduce signal loss and are suitable for high-frequency signal transmission.

[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
