Description
Technical Field
[0001] The utility model relates to the field of safes, in particular to a safe with an easily adjustable RFID antenna. Background Art
[0002] In today's safe deposit box market, innovative products are constantly emerging. Safe deposit boxes have made significant technological advancements in the current market. Many safe deposit boxes utilize advanced electronic lock technologies, such as fingerprint and iris recognition, significantly enhancing security. Some products also feature network monitoring capabilities, enabling real-time tracking and remote control of safe deposit box usage through connection to cloud servers. Regarding antenna technology, some products are beginning to incorporate antennas to enhance signal transmission and reception. However, most of these antennas are fixed and have relatively limited functionality. From a development perspective, safe deposit boxes are rapidly moving toward intelligent, multifunctional, and highly customizable features. For example, incorporating IoT technology not only enables remote control and management, but also allows integration with other smart devices to form a complete security network. New high-strength, fire-resistant, and waterproof materials are being used to further enhance the physical protection of safe deposit boxes. Big data analysis and artificial intelligence algorithms are being used to predict and optimize safe deposit box usage. However, existing safe deposit boxes with antennas still face numerous challenges. First, the control accuracy of antenna rotation is generally insufficient, which can lead to unstable signal coverage and signal blind spots at certain angles or locations, affecting the accurate transmission and reception of information. Second, in complex electromagnetic environments, these safes have relatively weak anti-interference capabilities and are easily affected by external electromagnetic waves, resulting in data transmission errors or interruptions.
[0003] In existing safe deposit box technology, antennas are typically fixedly mounted in a specific location within the cabinet, such as the top or side. For example, in the case of a top-mounted antenna, the antenna is directly fixed to the inside of the cabinet top, and its position and angle cannot be changed. When objects of varying shapes and sizes are placed within the cabinet, the fixed antenna position can block the antenna signal. For example, a tall file box can block signal transmission downward, resulting in insufficient signal coverage in the lower area. In complex storage situations, such as closely stacked and unevenly distributed items, a fixed antenna struggles to fully cover all items, thus affecting signal reading accuracy. When encountering metal objects, such as metal folders or reinforced structures within the cabinet, fixed antennas are susceptible to reflection and absorption, resulting in signal shielding and preventing effective signal reception in certain areas. In the presence of other interference sources, such as nearby electronic devices or electromagnetic radiation sources, the antenna cannot adjust its position to avoid interference, making it susceptible to interference, reducing system reliability and stability. In summary, existing fixed antenna solutions have significant limitations when dealing with diverse storage and complex environmental interference. Utility Model Content

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] A preferred embodiment of the present invention is a safe cabinet that is easy to adjust the RFID antenna; Figure 1-2 As shown, it includes a cabinet 10, with a set of side panels 18 provided on each of the left and right sides of the cabinet. The side panels are provided with multiple groups of support columns 180, and partitions 19 are installed on the support columns, some of which are connected to antenna assemblies 20 at their lower ends, and antenna assemblies 20 are also provided on the top of the inner wall of the cabinet, thereby forming multiple groups of antenna assemblies inside the cabinet. The cabinet 10 is open on one side, and the opening is connected to a left door 11 and a right door 12. The left door and the right door can be opened independently, and the cabinet is closed when they are closed at the same time. A maintenance door 14 is provided on the side of the cabinet, and a circuit module 25 is installed in the maintenance door. The maintenance door facilitates the maintenance and replacement of the circuit module, and the circuit module controls the operation of the antenna assembly to obtain information and related communications. In order to facilitate the placement of the safe, a support assembly 13 is provided at the bottom of the cabinet 10, and the safe can be moved and supported by the support assembly.
[0033] Specifically, such as Figure 3As shown, the antenna assembly 20 includes multiple antenna groups 201, each with identical structure. In this embodiment, four antenna groups are provided. Each antenna group comprises three layers of antenna panels 2010, with the topmost panel having the largest area, and the areas decreasing as the panels move downward. The topmost panel is connected to the cabinet or partition via a rotating post 2011. This rotating post allows the multiple antenna panels to rotate, adjusting the coverage area of the antenna group to meet different needs. Each antenna group is connected and secured by connecting posts 2012 and plug posts 2013. The length of the connecting posts can be adjusted as needed to adjust the distance between the antenna panels. Threaded connections are preferred for ease of adjustment. The bottommost connecting post is secured by a locking member 2014. To ensure sufficient antenna coverage, rotating posts are located at the corners of the antenna panels. This allows for a wide coverage area during rotation, allowing the antennas to be freely adjusted in angle and position within a certain range, thereby improving signal coverage and reading accuracy. The antenna assembly can be moved vertically and rotated horizontally using a motor or manual adjustment mechanism. The antenna's direction can be adjusted according to actual needs, ensuring signal coverage in every corner of the cabinet. To further improve the flexibility and reliability of antenna rotation, high-precision motors and sensors can be used to precisely control the antenna's rotation angle. The rotating column can also be adjusted by motor or manually, allowing the antenna to rotate horizontally to adjust its direction, ensuring signal coverage in every corner of the cabinet. High-precision motors and sensors can also be used to precisely control the antenna's rotation angle. The antenna's angle and position can also be automatically adjusted based on the placement of items in the cabinet and signal strength feedback. Alternatively, a multi-antenna array and signal amplifier can be used to enhance signal coverage and anti-interference capabilities. Multiple antenna groups can work together to reduce signal blind spots and interference.
[0034] Furthermore, the antenna may be installed via an antenna bracket, and the driving device may be used to drive the antenna bracket to rotate in the horizontal and vertical directions to drive the antenna to rotate and adjust the direction of the antenna.
[0035] Furthermore, if Figure 2 、 Figure 4 and Figure 6As shown in the figure, light strip assemblies 17 are provided on the left and right sides inside the cabinet body 10 near the left door and the right door. When the left door 11 or the right door 12 is opened, the light strip assembly on the corresponding side can emit light for illumination. The light strip assembly 17 includes a light strip bracket 170 connected to the cabinet body. There are U-shaped edges 174 provided on the left and right sides of the light strip bracket. A recessed groove 173 is formed between the two sets of U-shaped edges. The light strip 171 is placed in the recessed groove, and a light board 172 is provided above the light strip bracket. After the light strip emits light, it illuminates the light board. Since the light strip bracket is vertically distributed inside the cabinet, it plays a certain supporting role for the cabinet body. The light strip placed in the recessed groove improves the scattering after the light strip emits light, and the illumination effect is better. Moreover, the U-shaped edges 174 on both sides further enhance the strength of the light strip bracket.
[0036] Furthermore, as Figure 3-4 and Figure 7 shown, side plates 18 are provided on both the left and right sides of the inner wall of the cabinet body 10. The side plates are U-shaped as a whole. It includes a supporting side plate 181 and support columns 180 provided on the two sets of supporting side plates. The support columns are located on the opposite surfaces of the two supporting side plates. The partition can be placed on the two sets of opposite support columns, and the partition can be taken out by tilting it after lifting it. An antenna assembly is connected below the middle partition, so that the antenna assembly is kept parallel to the partition, shortening the signal propagation path and reducing interference at the same time, thereby improving the signal coverage effect and recognition rate. The antenna assembly can adopt a UHF RFID antenna assembly. The antenna assembly adopts a multi-antenna array and a signal amplifier to enhance the signal coverage ability and anti-interference ability. Through the collaborative work of multiple antennas, the signal blind area and interference influence can be effectively reduced. And a hollowed-out cavity 182 is formed between the supporting side plate and the inner wall of the cabinet body. A vertical column 183 is vertically provided in the hollowed-out cavity. The vertical column extends from the upper end of the supporting side plate to the lower end of the supporting side plate, thereby providing a certain supporting force for the upper end of the cabinet body, increasing the strength of the cabinet body, and at the same time improving the strength of the supporting side plate, enabling more items to be placed on each partition without causing deformation of the supporting side plate. At the same time, due to the hollowed-out cavity formed between the cabinet body and the supporting side plate, the safe cabinet also has a certain shock absorption property. When the cabinet body is vibrated, the hollowed-out cavity absorbs the vibration of the cabinet body, avoiding the vibration being transmitted to the supporting side plate and then to the partition. And wiring can be carried out in the hollowed-out cavity, which is convenient for the connection and installation of the circuit module and the antenna assembly.
[0037] Furthermore, as Figure 1 、 Figure 8 and Figure 11-13As shown, the right door 12 includes an outer door sheet metal 122 and an inner door sheet metal 121. A gap is left between the outer door sheet metal and the inner door sheet metal, and a display screen 120 is provided on the outer door sheet metal. The display information of the circuit module can be viewed through the display screen, and corresponding operations can also be performed, such as entering a password to unlock, changing the unlock password, etc. A locking member 125 is provided on the side of the right door, and an electric suction column 126 is connected to the locking member. The electric suction column passes through the upper end of the right door and can be locked into the right door, and can be moved by operating the electric suction column through the handle 124. An electric suction column fixing hole 27 is provided on the top of the cabinet corresponding to the electric suction column, and a door suction motor 29 is provided above the electric suction column fixing hole. When the door suction motor is powered off after unlocking, the handle can be turned to rotate the electric suction door out of the electric suction column fixing hole to open the right door. After the handle is turned to rotate the electric suction column into the electric suction column fixing hole, the door suction motor automatically locks and locks the right door. The upper and lower ends of the right door are rotatably connected to the cabinet body via a rotating shaft 123, so that the right door can be rotated relative to the cabinet body to open or close the right door. The left door and the right door have the same structure, except that the left door does not have a display screen. The other structures are the same as the right door, so they will not be repeated here.
[0038] Furthermore, if Figure 2 and Figure 4-5 As shown, the support assembly 13 includes a foot support 131 connected to the cabinet body and an adjustment nut 130 for adjusting the height of the foot support. The height of the foot support can be adjusted by turning the adjustment nut. The support assembly also includes casters 132. When the safe needs to be moved, the lower end of the foot support can be turned higher than the lower end of the caster to achieve movement, making movement easier. After moving to a desired position, the adjustment assembly can be turned so that the lower end of the foot support is higher than the lower end of the caster to secure the safe, providing greater stability and convenient adjustment.
[0039] Furthermore, if Figure 8-13As shown, the inner wall of the cabinet 10 is provided with multiple groups of support plates 21, and the support plates are provided on the back, bottom, top and sides of the cabinet to improve the strength of the safe. At the same time, a maintenance door 14 is provided on the side corresponding to the circuit module 25. The circuit module can be replaced and repaired by opening the maintenance door. An operation port 28 is provided on the back side of the cabinet, which is provided with a communication interface 22 and a socket 23. The safe is connected to the power supply through the socket to make it work. The switch 24 controls the opening and closing of the safe and transmits communication through the communication interface. A camera 26 is provided on the top of the safe. The camera and antenna assembly are both provided on the top of the cabinet and are hidden by a light-transmitting plate 200. The light-transmitting plate allows the antenna assembly and the camera to work normally. The cabinet's exterior features a top door 15, which reveals two shielding lamp assemblies 16 mounted on the cabinet via shielding lamp brackets and fitted with shielding lampshades 160. Opening the top door allows for easy replacement of the lamps. The battery compartment 31 and debugging box 30, which accompany the antenna assembly, can also be replaced by opening the top door, making operation more convenient. The shielding lamps enhance the cabinet's anti-interference capabilities, enabling it to operate even in environments with electromagnetic interference, ensuring signal stability and reliability.
