[0003] In order to overcome at least one of the defects mentioned above in the prior art, the present invention provides a data acquisition terminal capable of detecting tail cover opening, so as to solve the problem that the tail cover opening of the existing data acquisition terminal fails to be detected in time, thus affecting the normal use of the equipment.

[0004] The present invention provides a technical solution to address the problem by disclosing a data acquisition terminal capable of detecting the opening of a tail cover. The terminal includes a main body, a control board, a sensing component, and a tail cover. The control board is mounted on the main body, and the sensing component is located at the tail of the main body and electrically connected to the control board. When the tail cover is closed at the tail of the main body, pressing the sensing component causes the control board to detect a closing signal. When the tail cover is separated from the main body, the pressing force on the sensing component is released, causing the control board to detect an opening signal.

[0005] As an optional implementation, in this embodiment of the present invention, the sensing component includes a sensing switch and an elastic reset member. The sensing switch is electrically connected to the control board. When the tail cover is pressed, the sensing switch squeezes the elastic reset member and becomes electrically connected to the control board, so that the control board detects the closing signal. When the pressing force of the tail cover is removed, the sensing switch is reset under the action of the elastic reset member and disconnected from the control board, so that the control board detects the opening signal.

[0006] As an optional implementation, in this embodiment of the present invention, the elastic reset member is located inside the inductive switch, the inductive switch is provided with a pressing part, one end of the pressing part is located inside the inductive switch and abuts against the elastic reset member, and the other end of the pressing part extends outside the inductive switch for pressing.

One end of the pressing rod is located within the terminal body at a position corresponding to the inductive switch. The other end of the pressing rod is movably inserted through the clearance hole for the tail cover to press. When the tail cover presses the other end of the pressing rod, one end of the pressing rod presses the inductive switch. When the tail cover pressing force is released, the inductive switch resets and pushes one end of the pressing rod to drive the pressing rod to reset.

[0009] As an optional implementation, in this embodiment of the present invention, one end of the pressing rod is provided with a first limiting part and the other end is provided with a second limiting part, and the side of the clearance hole facing the inside of the terminal body is provided with a narrowing, and the outer diameter of the first limiting part and the second limiting part are both larger than the inner diameter of the narrowing.

[0029] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0030] Please refer to the following: Figures 1 to 5 This utility model discloses a data acquisition terminal capable of detecting tail cover opening. The terminal includes a main body 1, a control board, a sensing component 3, and a tail cover 4. The control board is mounted on the main body 1. The sensing component 3 is located at the tail of the main body 1 and electrically connected to the control board. When the tail cover 4 is closed at the tail of the main body 1, pressing the sensing component 3 detects a closing signal on the control board. When the tail cover 4 is separated from the main body 1, the pressing force on the sensing component 3 is released, allowing the control board to detect an opening signal. This design, by adding the sensing component 3, allows for timely detection of tail cover opening, ensuring the normal operation of the data acquisition terminal.

[0031] In some embodiments, in order for the sensing component 3 to achieve the switching between the two states mentioned above, the sensing component 3 includes a sensing switch 31 and an elastic reset member. The sensing switch 31 is electrically connected to the control board. When the tail cover 4 is pressed, the sensing switch 31 squeezes the elastic reset member and is electrically connected to the control board, so that the control board detects a closing signal. When the pressing pressure of the tail cover 4 is removed, the sensing switch 31 is reset under the action of the elastic reset member and disconnected from the control board, so that the control board detects an opening signal.

[0032] Furthermore, the elastic reset member is located inside the inductive switch 31, and the inductive switch 31 is provided with a pressing part 311. One end of the pressing part 311 is located inside the inductive switch 31 and abuts against the elastic reset member, and the other end of the pressing part 311 extends to the outside of the inductive switch 31 for pressing.

[0033] Furthermore, the terminal body 1 is provided with a first mounting port, and the induction switch 31 extends outward to form a mounting block 312. The mounting block 312 is provided with a second mounting port 313. The first mounting port and the second mounting port 313 are connected by fasteners to realize the installation and fixation of the induction switch 31 on the terminal body 1.

[0034] In some embodiments, the control board, the inductive switch 31, and the elastic reset member are all located inside the terminal body 1. In order for the tail cover 4 to press the inductive switch 31 located inside the terminal body 1, the terminal body 1 is provided with a clearance hole 121. The sensing component 3 also includes a pressing rod 32. One end of the pressing rod 32 is located inside the terminal body 1 at the position corresponding to the inductive switch 31, and the other end of the pressing rod 32 is movably inserted through the clearance hole 121 for the tail cover 4 to press. When the tail cover 4 presses the other end of the pressing rod 32, one end of the pressing rod 32 presses the inductive switch 31. When the pressing force of the tail cover 4 is released, the inductive switch 31 resets and pushes one end of the pressing rod 32 to drive the pressing rod 32 to reset.

[0035] Furthermore, the pressing rod 32 has a first limiting part 321 at one end and a second limiting part 322 at the other end. The side of the clearance hole 121 facing the inside of the terminal body 1 has a narrowing. The outer diameters of both the first limiting part 321 and the second limiting part 322 are larger than the inner diameter of the narrowing. This design can prevent the pressing rod 32 from detaching from the terminal body 1 and limit the travel of the pressing rod 32.

[0036] The terminal body 1 also includes a lower housing 11 and an upper housing 12, which are connected together. The control board, the induction switch 31 and the elastic reset component are located between the upper housing 12 and the lower housing 11. The tail cover 4 is closed on the tail of the upper housing 12, and the clearance hole 121 is provided on the upper housing 12.

[0037] In some embodiments, in order for the tail cover 4 to better press the sensing component 3, the tail cover 4 is provided with a pressing post 41 extending toward the sensing component. When the tail cover 4 is closed on the tail of the terminal body 1, the pressing post 41 presses the sensing component 3. When the tail cover 4 is separated from the terminal body 1, the pressing post 41 separates from the sensing component 3.

[0038] In some embodiments, in order for the tail cover 4 to be fixed to the terminal body 1, the terminal body 1 is provided with a first connection hole 111 and the tail cover 4 is provided with a second connection hole 42. The first connection hole 111 and the second connection hole 42 are connected by a connector to fix the tail cover 4 to the terminal body 1.

[0039] Furthermore, the tail of the data acquisition terminal is provided with a groove 13. When the tail cover 4 is closed on the tail of the terminal body 1, it is located in the groove 13, so that the connection between the tail cover 4 and the terminal body 1 is smooth. This design makes the overall structure of the data acquisition terminal that can detect the opening of the tail cover stronger and also makes it easier for the user to hold during use.

[0040] This utility model provides a data acquisition terminal capable of detecting the opening of a tail cover, comprising a terminal body 1, a control board, a sensing component 3, and a tail cover 4. The control board is disposed on the terminal body 1, and the sensing component 3 is disposed at the tail of the terminal body 1 and electrically connected to the control board. When the tail cover 4 is closed at the tail of the terminal body 1, pressing the sensing component 3 causes the control board to detect a closed signal. When the tail cover 4 is separated from the terminal body 1, the pressing force on the sensing component 3 is released, causing the control board to detect an open signal. By adopting this design, and by adding the sensing component 3, pressing the sensing component 3 when the tail cover 4 is closed detects a closed signal, and releasing the external force on the sensing component 3 when the tail cover 4 is open detects an open signal, thus enabling timely detection of the tail cover 4 being open and ensuring the normal operation of the data acquisition terminal.

This article uses specific examples to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the data acquisition terminal capable of detecting tail cap opening and its core idea. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
