Description

Technical Field

[0001] This utility model relates to the field of card reader technology, and in particular to a snap-on type easy-to-maintain and tamper-proof RFID card reader module. Background Technology

[0002] Radio Frequency Identification (RFID) technology, as a non-contact automatic identification technology, has been widely used in various electronic instruments and equipment for identity authentication, access control, item tracking, and data collection due to its advantages such as long-range reading, high storage capacity, and rewritable capabilities. In these applications, the RFID card reader module is the core component for realizing data sensing and communication.

[0003] To achieve a pleasing aesthetic and a secure seal, the typical design integrates the RFID reader module directly into the instrument's casing. This built-in installation usually involves securing the reader to the inner wall or support using screws or adhesive, with only a corresponding card-reading identifier printed on the casing surface. This design provides a clean, integrated appearance at the time of shipment and offers good protection for the internal components.

[0004] However, this traditional built-in fixing method reveals significant structural flaws throughout the product's lifecycle, especially during later maintenance and repair stages. When the RFID reader module needs replacement due to performance degradation or accidental damage from long-term use, maintenance personnel must completely disassemble the entire instrument casing, such as the back cover or overall housing, to access the internally fixed reader module. This process is not only cumbersome and time-consuming but also places high demands on the maintenance environment and the professionalism of the personnel.

[0005] More seriously, disassembling the equipment casing often means disconnecting or dealing with the complex internal wiring. When replacing the card reader module, maintenance personnel are prone to misconnecting or missing wires due to unfamiliarity with the internal layout, and may even cause physical damage to other precision components during disassembly and assembly. This not only increases the difficulty and risk of maintenance, but also greatly prolongs equipment downtime and increases overall maintenance costs. Therefore, this utility model proposes a snap-on, easy-to-maintain, tamper-proof RFID card reader module to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a snap-on, easy-to-maintain, and detachable RFID card reader module, which aims to improve the problems of cumbersome disassembly and assembly, and inconvenient maintenance and replacement caused by the fact that some card reader modules in the prior art are fixed inside the equipment shell.

[0007] This utility model provides a snap-on type easy-to-maintain and tamper-proof RFID card reader module, including: an instrument housing, a mounting base installed on the instrument housing, and a card reader installed on the mounting base; and a snap-on mechanism for locking the mounting base to the instrument housing and facilitating its disassembly.

[0008] The latching mechanism includes a female latch located on the outside of the fixed base, a male latch rotatably connected to the inside of the instrument housing via a fixed shaft, a spring 1 located between the male latch and the instrument housing, an unlocking block connected to the male latch, and a spring 2 located between the instrument housing and the fixed base.

[0009] Furthermore, the female buckle on the fixing seat and the male buckle on the instrument housing are combined by engaging or disengaging. The first spring applies a reset force to the male buckle to drive it to automatically engage with the female buckle. The unlocking block drives the male buckle to rotate under the action of external force to disengage from the female buckle. The second spring provides a force to pop the fixing seat out of the instrument housing when the male buckle and the female buckle are unlocked.

[0010] Preferably, the male buckle has a guide slope at the top. During the process of the fixing seat being pressed into the instrument housing, the edge of the female buckle presses against the guide slope, thereby forcing the male buckle to rotate around the fixing axis against the elastic force of the spring.

[0011] Preferably, the female buckle has a groove that matches the male buckle. When the fixing seat is installed in place, the male buckle is reset and locked into the groove under the elastic force of the spring.

[0012] Preferably, a metal contact one is provided at the mounting position of the instrument housing, and a metal contact two is provided at the corresponding position of the fixing base; when the fixing base is installed on the instrument housing, the metal contact two abuts against the metal contact one to form a detachable electrical connection.

[0013] Preferably, the card reader is fixedly soldered to the back of the second metal contact via a wire, thereby transmitting electrical signals to the mounting base.

[0014] Preferably, the top surface of the mounting base is integrally formed with a mounting post, and the bottom of the card reader is provided with a slot adapted to the mounting post. The card reader is fixed to the mounting base by the cooperation of the mounting post and the slot.

[0015] Preferably, the snap-on easy-maintain and tamper-proof RFID card reader module further includes a connecting block, which is disposed between the second spring and the fixed base to transmit the elastic force of the second spring.

[0016] Preferably, a portion of the unlocking block's structure passes through a pre-drilled hole in the instrument housing and is exposed to the outside, allowing the operator to perform a pressing operation from the outside.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a buckle mechanism composed of male buckle, female buckle, unlocking block and spring, enables the card reader module's fixing seat to quickly snap into or pop out of the instrument shell. This solves the problem in the prior art where the card reader module is built into the device, and maintenance and replacement require disassembling the entire instrument shell, which is cumbersome and time-consuming. It achieves the technical effect of simplifying the maintenance process and improving replacement efficiency.

[0019] 2. This utility model solves the technical problem of the risk of incorrect wiring or damage to components in the prior art by setting metal contacts one and two at corresponding positions on the fixed base and the instrument shell, which automatically align and contact each other instead of the traditional manual wire plugging and unplugging. It achieves the technical effect of avoiding electrical connection errors, reducing the skill requirements of maintenance personnel and improving operational safety.

[0020] 3. This utility model, by setting a second spring that can pop out the fixed seat after unlocking, provides a continuous preload force to the fixed seat in the locked state, which solves the problem that the buckle connection may loosen or make abnormal noise due to vibration or long-term use in the prior art, and achieves the technical effect of eliminating assembly gaps, enhancing connection stability and vibration resistance, and improving the long-term reliability of the product.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Example:

[0031] Reference Figures 1 to 4 This utility model provides a snap-on, easy-to-maintain, and tamper-proof RFID card reader module, which aims to solve the technical defects of the prior art where the RFID card reader module is fixed inside the shell, resulting in inconvenient maintenance and replacement and easy wiring errors.

[0032] like Figure 1 As shown, the device includes an instrument housing 1 and a mounting base 2 detachably mounted on the instrument housing 1. The instrument housing 1 serves as the mounting base for the entire device, while the mounting base 2 supports the card reader 3 and allows for quick separation and installation from the instrument housing 1. A mounting post 5 is integrally formed on the top surface of the mounting base 2, such as... Figure 3 As shown, the bottom of the card reader 3 has a corresponding slot adapted to the fixing post 5. The card reader 3 is fixed to the fixing base 2 through the cooperation of the fixing post 5 and the slot. A metal contact 6 is provided at the mounting position of the instrument housing 1, and a metal contact 7 is provided at the corresponding position of the fixing base 2. When the fixing base 2 is installed on the instrument housing 1, the metal contact 7 abuts against the metal contact 6 to form a detachable electrical connection. The card reader 3 is fixedly soldered to the back of the metal contact 7 by a wire, thereby transmitting the electrical signal to the fixing base 2. The snap-on easy-maintain and detachable RFID card reader module also includes a snap-on mechanism 4 for locking the fixing base 2 to the instrument housing 1 and facilitating its removal, such as... Figure 2 and Figure 3 As shown, the latching mechanism 4 includes a female latch 41 disposed on the outside of the fixed base 2 and a male latch 42 installed inside the instrument housing 1.

[0033] Reference Figure 2 , Figure 3 and Figure 4The latching mechanism 4 includes a male latch 42 rotatably connected to the instrument housing 1 via a fixed shaft 43, an unlocking block 44 for driving the male latch 42 to rotate, and a spring 45 and a spring 46 providing elastic force. The male latch 42 has a claw structure for engaging with the female latch 41 and a guide ramp for guiding its rotation when pressed. The fixed shaft 43 passes through the rotation hole of the male latch 42 to pivotally connect it to the instrument housing 1. The unlocking block 44 is driven to connect to the male latch 42, and part of its structure passes through the reserved through hole of the instrument housing 1 and is exposed to the outside. One end of the spring 45 is connected to the male latch 42, and the other end is connected to the instrument housing 1, for applying a reset torque to the male latch 42. The spring 46 applies a continuous popping force to the fixed seat 2 through the connecting block 47.

[0034] A female buckle 41 is integrally formed on the outer wall of the fixing base 2. The female buckle 41 has a groove that matches the claw of the male buckle 42. In the assembled state, when the fixing base 2 is pressed into the instrument housing 1, the edge of the female buckle 41 first presses the guide slope of the male buckle 42, forcing the male buckle 42 to rotate around the fixing shaft 43 and compress the spring 45. After the fixing base 2 is installed in place, the male buckle 42 quickly returns to its original position under the elastic force of the spring 45, and its claws are engaged in the groove of the female buckle 41 to form a stable locking fit. This engaging structure of the male buckle 42 and the female buckle 41 ensures the reliability of the connection between the fixing base 2 and the instrument housing 1.

[0035] Reference Figure 2 and Figure 3 The male buckle 42 has a guide slope at its top. During the process of pressing the fixing seat 2 into the instrument housing 1, the edge of the female buckle 41 presses against the guide slope, thereby forcing the male buckle 42 to rotate around the fixing shaft 43 under the force of the spring 45. The female buckle 41 has a groove that matches the male buckle 42. When the fixing seat 2 is installed in place, the male buckle 42 is reset and locked into the groove under the force of the spring 45. A metal contact 6 is provided at the installation position of the instrument housing 1, and a metal contact 7 is provided at the corresponding position of the fixing seat 2. When the fixing seat 2 is installed on the instrument housing 1, the metal contact 7 and the metal contact 6... Metal contacts 6 abut against each other to form a detachable electrical connection. The card reader 3 is fixedly soldered to the back of metal contact 7 via a wire. The top surface of the mounting base 2 is integrally formed with a mounting post 5. The bottom of the card reader 3 is provided with a slot that matches the mounting post 5. The card reader 3 is fixed to the mounting base 2 through the cooperation of the mounting post 5 and the slot. The elastic force of the second spring 46 is transmitted to the mounting base 2 through the connecting block 47. The connecting block 47 is located between the second spring 46 and the mounting base 2. Part of the structure of the unlocking block 44 passes through the reserved through hole of the instrument housing 1 and is exposed to the outside, so as to facilitate the operator to perform the pressing operation.

[0036] The implementation principle of this application embodiment is as follows: During installation, the mounting base 2 with the card reader 3 is aligned with the groove of the instrument housing 1 and pressed down. The female buckle 41 on the edge of the mounting base 2 will first contact and press the guide slope on the top of the male buckle 42. This pressing force forces the male buckle 42 to rotate around the fixed shaft 43, while compressing the spring 45. When the mounting base 2 is fully in place, the male buckle 42 passes over the edge of the female buckle 41 and quickly rotates in the opposite direction under the restoring force of the spring 45. Its claw structure accurately engages in the groove of the female buckle 41, completing the locking process. During this process, the metal contact 7 at the bottom of the mounting base 2 also contacts and conducts electricity with the metal contact 6 at the bottom of the instrument housing 1, automatically establishing an electrical connection.

[0037] During disassembly, the operator presses the exposed unlocking block 44 from the outside. The unlocking block 44 transmits external force to the male buckle 42, driving the male buckle 42 to rotate around the fixed shaft 43 again, causing its claws to disengage from the groove of the female buckle 41 and release the locking state. Once the lock is released, the spring 46, which was compressed and stored elastic energy during installation, exerts its elastic force on the fixed base 2 through the connecting block 47, instantly popping the entire fixed base 2 along with the card reader 3 out of the instrument housing 1, allowing the operator to easily remove the module. Through this snap-fit ​​installation and one-click pop-out structure, this utility model solves the problem in the prior art that replacing the card reader module requires disassembling the entire back panel of the device, which is cumbersome and prone to incorrect wiring.
