Technical Field

[0001] This invention belongs to the field of data acquisition equipment technology, and in particular relates to a handheld terminal for Internet of Things (IoT) data acquisition. Background Technology

[0002] The Internet of Things (IoT) is an information carrier based on the Internet, traditional telecommunications networks, etc. It enables all ordinary physical objects that can be independently addressed to form an interconnected network. The application fields of IoT involve all aspects. In infrastructure fields such as industry, agriculture, environment, transportation, logistics, and security, its application has effectively promoted the intelligent development of these fields, enabling more rational use and allocation of limited resources, thereby improving industry efficiency and effectiveness. In fields closely related to life such as home, healthcare, education, finance and services, and tourism, its application has greatly improved in terms of service scope, service methods, and service quality, significantly enhancing people's quality of life.

[0003] IoT handheld terminals are intermediate devices belonging to the sensor network layer and the transmission network layer. They are also key devices in the Internet of Things (IoT). Through the conversion and collection of data by the terminal, data collected by various external sensors can be gathered and processed, and the data can be transmitted to the Internet through various network interfaces. Without the existence of IoT terminals, sensor data cannot be delivered to the designated location, and the IoT will cease to exist. With the continuous development of technology, all kinds of IoT terminals have appeared on the market, and IoT terminals with various shapes, structures and functions also have their own characteristics.

[0004] When not in use, existing IoT data collection handheld terminals are often left lying around on tables for easy access. However, this requires picking them up again when data collection is needed. On the one hand, tables are often cluttered with other items, and leaving the handheld terminals lying around increases the untidiness of the table. On the other hand, items on the table can easily bump into the handheld terminals, or they can be accidentally knocked off, increasing the damage rate. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a handheld terminal for Internet of Things (IoT) data acquisition that can be stably placed when not in use, thereby reducing the damage rate.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] Specific embodiments of the IoT data acquisition handheld terminal of the present invention:

[0033] like Figure 1 As shown, the IoT data acquisition handheld terminal includes a handheld body, a handle 7, a transmission mechanism, a locking block 10, and a base 18.

[0034] Specifically, such as Figure 1As shown, the handheld unit includes a horizontal housing 1 and a vertical housing 2 connected together. A cover 3 is hinged to the left end of the horizontal housing 1. A drive board 29 and a mounting plate 42 are installed inside the horizontal housing 1. A scanning module 4 is fixedly connected to the left end of the drive board 29. An IoT module 5 is fixedly connected to the rear of the scanning module 4 inside the horizontal housing 1. The IoT module 5 is connected to a main control PCB board 33. The scanning module 4, IoT module 5, and main control PCB board are all existing technologies and are interconnected. A battery module 6 is installed inside the vertical housing, and a power switch 41 is externally mounted. The battery module 6 is a battery pack and is electrically connected to the scanning module 4, IoT module 5, main control PCB board 33, and power switch 41. The scanning module 4 can scan barcodes on goods and send the data to the IoT module 5. The IoT module 5 is connected to the terminal via a local area network.

[0035] like Figure 1 and Figure 2 As shown, the vertical housing 2 contains two telescopic cylinders 9 arranged vertically at intervals. Each telescopic cylinder 9 has a piston rod 8 mounted within it, moving in a left-right direction. The piston rods 8 pass through the vertical housing 2, and the handle 7 is connected to both piston rods 8. A second spring 28 connects the side of the piston rod 8 facing away from the handle 7 to the inner wall of the telescopic cylinder 9. When a person grips the handle 7, the elastic force of the second spring 28 causes the handle 7 to move closer to the vertical housing 2. When the handle 7 is released, it returns to its original position. For ease of gripping, the side of the handle 7 facing away from the vertical housing 2 is wavy.

[0036] A transmission mechanism is provided between the handle 7 and the scanning module 4, such as... Figure 1 and Figure 4 As shown, the transmission mechanism includes a first transmission rod 34, a second transmission rod 35, and a third transmission rod 36. Both the first and second transmission rods 34 and 35 extend vertically, while the third transmission rod 36 extends horizontally. The first transmission rod 34 is fixed to the upper piston rod 8 and located within the vertical housing 2. The top surface of the first transmission rod 34 is a first driving inclined surface 22. The second transmission rod 35 extends vertically and has a movable elongated hole 23. A rod 24, passing through the movable elongated hole 23, is provided within the vertical housing 2. The rod 24 supports the second transmission rod 35. The bottom surface of the second transmission rod 35 is a second passive inclined surface 25 adapted to the first driving inclined surface 22, and the top surface of the second transmission rod 35 is a second driving inclined surface 26. The left end of the third transmission rod 36 passes through the mounting plate 42 and connects to the drive plate 29. The part of the third transmission rod 36 located between the mounting plate 42 and the drive plate 29 is fitted with a third spring 32. The right end face of the third transmission rod 36 is a third passive inclined surface 27 adapted to the second drive inclined surface 26.

[0037] A guide post 38 extending vertically is provided on the vertical housing 2. The locking block 10 is sleeved on the guide post 38 and can move up and down on the guide post 38. A limiting block 39 is provided at the bottom end of the guide post 38 to prevent the locking block 10 from falling off the guide post 38. A drive rod 11 is hinged between the locking block 10 and the bottom end of the handle 7. The drive rod 11 is used to drive the locking block 10 to move up and down. A mounting groove 12 extending horizontally is provided in the locking block 10. A stop block 13 is provided in the mounting groove 12. A first spring 14 is connected between the stop block 13 and the bottom of the mounting groove 12. An upwardly extending stop protrusion 15 is integrally formed on the left end of the stop block 13.

[0038] like Figure 3 As shown, the base 18 is detachably connected to the handheld body. The base 18 is provided with a slot 19 that is compatible with the vertical housing 2. The bottom surface of the vertical housing 2 is an inclined slope. The bottom of the slot 19 gradually slopes upward from left to right. A charging plug 20 is provided in the slot 19. A charging interface 21 that is electrically connected to the charging plug 20 is provided on the bottom surface of the vertical housing 2. The charging interface 21 is electrically connected to the battery module 6. The charging plug 20 can be connected to an external power source to charge the battery module 6. The charging principle here is existing technology, and the specific charging structure will not be described in detail.

[0039] like Figure 1 and Figure 5 As shown, a support rod 16 is mounted on the left side of the slot 19 on the base 18. The support rod 16 has a through hole 17 extending through itself in the left-right direction, through which the stop block 13 passes. The top surface of the support rod 16 is a guide slope 40 inclined towards the vertical housing 2. In the initial state, the stop block 13 extends out of the mounting slot 12 and is located above the guide slope 40. The surface of the stop block 13 that contacts the guide slope is an arc surface.

[0040] The base 18 is provided with a slide rail 30 extending in the left and right direction, the support rod 16 is provided with a slide groove that slides with the slide rail 30, the left end of the slide rail 30 is provided with a fixing block 31, and a fourth spring 37 is connected between the fixing block 31 and the support rod.

[0041] When in use, the handheld body is detached from the base 18. The operator turns on the power switch 41, holds the handle 7, and presses the handle 7. At this time, the first transmission rod 34 moves to the right and pushes the second transmission rod 35 upward. The second transmission rod 35 pushes the third transmission rod 36, causing the third transmission rod 36 to move to the left. This pushes the scanning end of the scanning module 4 to extend out of the horizontal housing 1. The operator can then hold the handle and scan the QR code through the scanning module 4. Each scan record is sent to the Internet of Things module 5. After use, insert the vertical housing 2 into the slot 19 on the base 18. At this time, the handle 7 is in an unattended state. After insertion, the operator holds the handle 7. At this time, the drive rod 11 pushes the locking block 10 downward. The arc surface of the stop block 13 on the locking block 10 presses against the guide slope 40 and moves downward. At this time, under the action of the first spring 14, the stop block 13 retracts into the mounting groove 12 until the stop block 13 moves to the position of the through hole 17. At this time, under the action of the first spring 14, the stop block 13 is pushed into the through hole 17. The stop protrusion 15 on the stop block 13 and the support rod 16 stop in the left and right direction. Release the handle 7. Under the action of the second spring 28, the handle 7 moves to the left. At this time, the drive rod 11 pulls the locking block 10 upward until the locking block 10 abuts against the support rod 16 to form a lock, ensuring a stable connection between the handheld body and the base 18. At this time, the scanning module 4 will not extend out of the horizontal housing 1. When using it again, press the handle 7 to move the locking block 10 downwards until the stop block 13 can be disengaged from the through hole 17. Then pull the support rod 16 to the left to disengage the support rod 16 from the stop block 13, and you can take out the handheld body.

[0042] This invention allows for the detachable assembly of the handheld unit and the base. During use, the handheld unit can be removed from the base for individual operation. After use, the handheld unit is inserted into the slot on the base, and the handle is gripped to lock the stop block on the locking block and the support rod on the base, thus stably assembling the handheld unit and the base together. The entire assembly can then be placed on a table, preventing damage caused by careless placement.

[0043] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
