Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) smart terminal technology, and in particular to a handheld scanning device that combines Bluetooth signal acquisition, NFC identification, active heat dissipation, and a quick-assembly / disassembly structure. Background Technology

[0002] With the rapid development of IoT technology, the demand for portable identification terminals in fields such as warehousing and logistics, industrial production, facility inspection, and asset management continues to increase. Bluetooth signal detection and NFC tag recognition technologies complement each other and are widely used in various work scenarios such as inventory management, equipment filing, on-site data collection, and identity verification.

[0003] Existing conventional handheld scanning devices have numerous structural design shortcomings. The overall casing often uses a piecemeal structure with a single fixing method, which easily leads to problems such as casing loosening, increased gaps, and dust accumulation after long-term use, affecting the stable operation of internal components. Furthermore, traditional devices have rudimentary heat dissipation designs, relying solely on natural heat dissipation from the casing surface. During prolonged continuous operation, the main control circuit board continuously generates heat, which cannot be effectively dissipated, easily causing the device temperature to rise and leading to problems such as operational lag, signal drift, Bluetooth disconnection, and data loss, making it difficult to meet the requirements of high-intensity, long-term operation.

[0004] The existing equipment has an unreasonable power supply structure design. Batteries are generally fixed with bolts or simple clips, making disassembly and assembly cumbersome and replacement time-consuming, which cannot meet the needs of multi-shift, high-intensity on-site operations. Conventional clip structures have poor stability and are prone to deformation under long-term vibration and impact, which can lead to poor power supply contact and unexpected power outages, seriously affecting the continuity of operations.

[0005] Meanwhile, the Bluetooth signal acquisition component has a simple structure, lacking a dedicated signal convergence structure and external protection structure. External electromagnetic interference, dust, debris, and external impacts can significantly reduce signal reception sensitivity, shorten the recognition distance, and increase the recognition error rate. Furthermore, the device's data interface functions are mixed, with power supply and data transmission sharing an interface, which is prone to electromagnetic interference and causes data transmission abnormalities. The device's single function cannot simultaneously handle Bluetooth acquisition and NFC recognition, limiting its applicable scenarios.

[0006] In summary, existing scanning devices suffer from insufficient structural stability, poor heat dissipation, inconvenient assembly and disassembly, weak signal interference resistance, and limited functionality, exhibiting significant drawbacks. Therefore, designing an integrated scanning device with a robust structure, efficient heat dissipation, convenient assembly and disassembly, stable signal, and multifunctional integration is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0007] One objective of this invention is to propose a multi-functional integrated Bluetooth scanning device based on Bluetooth. This invention achieves a highly integrated, stable, reliable, efficient heat dissipation, convenient assembly and disassembly, and accurate signal acquisition multi-functional scanning terminal through an integrated gun-type housing structure, a dedicated quick-release battery structure, an active heat dissipation mechanism, a signal acquisition and convergence structure, and an NFC identification module.

The push plate is fixed to the bottom of the latch, and the return spring is located between the push plate and the bottom wall of the inner cavity of the outer shell to lift the latch and maintain the latched state with the battery. The top of the battery also has a circuit protection module embedded inside the outer shell.

[0016] Furthermore, the signal processing module is a main control circuit board that integrates a Bluetooth communication module and a data processing unit; a finned heat sink is fixedly connected to the bottom of the signal processing module, and the finned heat sink is fixedly connected to the inner wall of the outer shell through a fastener.

[0017] The advantages of adopting the above-mentioned further solutions are: the highly integrated design integrates multiple functions, making the internal structure more compact and reducing the space occupied by the equipment; the finned heat sink has a large-area heat dissipation structure, which can quickly absorb the heat generated by the operation of the main control components and accelerate its diffusion, forming a composite heat dissipation system with the active heat dissipation mechanism, effectively suppressing heat accumulation, avoiding component performance degradation, signal fluctuations or equipment crashes caused by high temperature, and ensuring stable operation of the equipment for a long time; the fixed connection method ensures that the finned heat sink is tightly attached to the main control module, improving heat conduction efficiency, while also ensuring the installation stability of the signal processing module.

[0018] Furthermore, the signal acquisition end is a Bluetooth signal acquisition component, electrically connected to the signal processing module, used to receive external Bluetooth signals; the signal acquisition end includes an acquisition probe, and a fixing plate is fixed to the outside of the acquisition probe by a fixing component; the fixing plate is hollowed out and snapped into the inside of the outer shell; a funnel-shaped manifold is provided on the outside of the acquisition probe, and a transparent protective cover is provided at the larger opening end of the manifold; the transparent protective cover is snapped into the inside of a sleeve, and the sleeve is fitted onto the outside of the outer shell and snapped into the outer shell.

[0019] The advantages of adopting the above-mentioned further solutions are that the hollowed-out fixing plate ensures the stable fixation of the components while not hindering the propagation of Bluetooth signals, thus ensuring signal penetration; the funnel-shaped manifold can effectively gather scattered Bluetooth signals, improve receiving sensitivity and identification stability, and reduce external electromagnetic interference; the transparent protective cover is sturdy and can effectively block dust, debris and external collisions, providing all-round protection for the acquisition probe, extending the service life of the components, and improving the environmental adaptability of the equipment; the snap-fit ​​fixing structure facilitates disassembly and maintenance, reducing later maintenance costs.

[0020] Furthermore, the NFC integrated module is fixedly installed on the top of the housing and electrically connected to the signal processing module for NFC tag identification, information reading and data interaction; the outer side of the NFC integrated module is provided with a protective structure flush with the housing.

[0021] The advantages of adopting the above-mentioned further solutions are that the top embedded installation makes the recognition area unobstructed, the tag sensing range is uniform, and the recognition response is rapid; the independent circuit connection design avoids cross-interference between Bluetooth and NFC signals, and can realize the two functions simultaneously, enriching the application scenarios of the equipment and meeting the needs of composite operations such as material filing and equipment verification; the flush design does not affect the grip feel and overall aesthetics of the equipment.

[0022] Furthermore, the heat dissipation mechanism is fitted to the signal processing module and is powered by a battery to achieve active heat dissipation. The heat dissipation mechanism includes a motor, with a fan blade fixedly connected to the motor output end. A fixed housing is fixed to the outside of the motor, and T-shaped rods that engage with the outer shell are provided at both the top and bottom ends of the fixed housing. A horizontally arranged anti-deviation frame is engaged with the outside of the fixed housing, and the outer shell is fixedly connected to the anti-deviation frame from the outside through fasteners. The outer shell has heat dissipation holes at the positions corresponding to the heat dissipation mechanism.

[0023] The beneficial effects of adopting the above-mentioned further solutions are that the heat dissipation efficiency of the active air-cooled heat dissipation mechanism is much higher than that of traditional natural heat dissipation. The close proximity to the main control module shortens the heat conduction path and can quickly remove the heat accumulated inside. The T-shaped rod and the anti-deviation bracket form a double fixation, which effectively suppresses the vibration and deviation of the motor and fan blades during operation, reduces operating noise, and prevents the heat dissipation components from loosening and shifting. The heat dissipation holes, together with the fan blades, form air convection, accelerate the heat dissipation, ensure the long-term stable operation of the heat dissipation mechanism, maintain the stable internal temperature of the equipment, and avoid the impact of high temperature on the performance of core components such as the signal processing module.

[0024] Furthermore, the device is an integrated gun-type intelligent IoT scanning terminal with Bluetooth signal acquisition, NFC identification, and active heat dissipation functions, suitable for asset inspection, equipment positioning, intelligent inventory of materials, and identity recognition scenarios.

[0025] The advantages of adopting the above-mentioned further solutions are that the integrated structural design makes the equipment compact and lightweight, easy to carry, and adaptable to various complex working conditions such as industrial plants, warehousing and logistics, and outdoor facilities; the multi-functional integration eliminates the need for multiple devices, simplifies the operation process, and improves work efficiency; it is easy to operate, requiring no complicated training to get started, and can meet the needs of intelligent data collection in multiple industries, with a wide range of applications.

[0043] The outer shell 1 is a one-piece handheld shell in the shape of a gun, consisting of a main body and a grip. The outer shell 1 is composed of a front shell and a rear shell that fit together, secured by a double-locking mechanism via a fixing plate 602 and a retainer 605 on the signal acquisition terminal 6. The outer shell 1 is injection molded from high-strength alloy material, and the outer side of the grip has an anti-slip coating. The high-strength alloy material enhances structural strength and impact resistance, making it suitable for complex working environments. The sealed structure prevents dust and moisture intrusion, protecting internal components. The anti-slip coating enhances grip stability and reduces hand fatigue. The overall assembly requires no large number of screws, making assembly and maintenance more convenient.

[0044] Battery 3 is a rechargeable lithium battery, which can be quickly installed and removed via a snap-fit ​​structure 2. The snap-fit ​​structure 2 includes a latch 201, a push plate 202, and a return spring 203. One end of the latch 201 is exposed for easy manual unlocking, while the other end extends into the housing 1 to snap into the battery 3. The return spring 203 provides continuous clamping force to maintain a stable snap-fit. A circuit protection module 12 is located on the top of the battery 3. The snap-fit ​​structure 2 allows for quick replacement of the battery 3 without tools; the return spring 203 ensures a secure snap-fit ​​and prevents power loss due to vibration; the circuit protection module 12 improves power supply safety and extends the lifespan of the battery 3 and the entire device.

[0051] Example 1: Warehousing and Logistics Inventory Scenario In a large warehousing and logistics center, goods are densely stacked, and staff need to quickly complete inventory, verification, and location. When using this equipment, the operator holds the device and scans the Bluetooth tags of the goods from a distance using the Bluetooth signal acquisition function. The signal acquisition end 6's junction cover 603 focuses the signal, ensuring stable identification in complex environments. For key goods, the tag information can be verified at close range using the top NFC integrated module 8, without the need for additional equipment. The sealed structure of the outer shell 1 protects against warehousing dust, and the heat dissipation mechanism 7 ensures uninterrupted operation for extended periods. The battery 3 can be quickly replaced without interrupting operations. Inventory data can be stably exported through the expansion connection port 9, achieving efficient digital management of warehousing materials.

[0052] Example 2: Industrial Plant Equipment Inspection Scenario Industrial plants have widely distributed equipment and complex environments. When using this equipment for inspection, it achieves long-distance equipment identification and positioning through Bluetooth signal acquisition.

[0053] Example 3: Smart Park Asset Verification Scenario. Smart parks have a wide variety of assets distributed over a wide area.

Verification data can be exported to the management platform in real time to realize intelligent and efficient management of park assets.

[0054] Working principle: When the device is working, the battery 3 is securely fixed inside the outer casing 1 by the snap-fit ​​structure 2. The snap-fit ​​201 is snapped into the bottom slot of the battery 3 under the pre-tightening force of the return spring 203, ensuring that the battery 3 is tightly attached to the power supply contacts. The circuit protection module 12 monitors the power supply voltage, current and temperature of the battery 3 in real time to avoid faults such as overvoltage, overcurrent, short circuit and overheating, and provides stable power supply to all electrical components such as the signal processing module 5, signal acquisition terminal 6, NFC integrated module 8, heat dissipation mechanism 7, etc. After the device is started, it enters the standby state.

[0055] The operator holds the device and presses the trigger mechanism 4. The trigger signal is transmitted to the signal processing module 5 through the transmission structure, activating the Bluetooth signal acquisition function. The acquisition probe 601 of the signal acquisition end 6 begins to receive external Bluetooth signals. The funnel-shaped manifold 603 gathers and integrates the scattered signals, reduces external electromagnetic interference, and improves the stability of signal acquisition. The acquired signal data is transmitted to the Bluetooth communication module of the signal processing module 5, and after being parsed and processed by the data processing unit, it is stored inside the device.

[0056] During long-term operation of the equipment, the main control component of the signal processing module 5 continuously generates heat. The heat is quickly conducted and diffused through the bottom finned heat sink 11. At the same time, the motor 701 of the heat dissipation mechanism 7 drives the fan blades 702 to rotate, forming a directional airflow. This, together with the heat dissipation holes of the outer casing 1, forms air convection, quickly removing the heat accumulated inside, maintaining a stable internal temperature, and avoiding component performance degradation or equipment failure caused by high temperature.

[0057] When NFC identification is required, the operator places the NFC integrated module 8 on the top of the device close to the target NFC tag. The NFC integrated module 8 senses and reads the tag information, and the data is synchronously transmitted to the signal processing module 5 for integration and storage, completing information identification and interaction. The independent circuit connection design avoids cross-interference between Bluetooth and NFC signals, ensuring that the two functions operate independently and stably.

[0058] During operation, the ejector spring 10 of the trigger mechanism 4 ensures quick reset after pressing, facilitating continuous high-frequency scanning operation. When the battery 3 is low on power, the operator moves the latch 201 on the outside of the housing 1 to compress the reset spring 203, releasing the battery 3 from the latching restriction. The battery 3 can then be quickly removed and replaced with a spare battery 3. After replacement, the latch 201 is released, and the reset spring 203 pushes the latch 201 to reset and lock the battery 3, restoring power supply.

[0059] After the operation is completed, the operator connects to an external device via USB expansion port 9 to export the data stored in the device. The independent data transmission design ensures data integrity and no interference. When the port is not in use, the dustproof and waterproof plug is installed to seal and protect the expansion port 9. The overall operating logic of the equipment is clear, and all components work together to meet the needs of multi-scenario and high-intensity operations.
