The present invention will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments are not intended to limit the present invention, and structural, methodical, or functional changes that may be made by one of ordinary skill in the art based on these embodiments are all included in the scope of the present invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

In the following, some embodiments of the present invention will be described in detail with reference to the accompanying drawings, and features in the following examples and embodiments may be combined with each other without conflict.

As shown in fig. 1 to fig. 3, a case 10 according to an embodiment of the present invention includes a case 1, a case cover 2 assembled to the case 1, and a detection device 3. In this embodiment, the enclosure 10 is used to mount a single board and/or electronic components required by electronic equipment (e.g., a switch, a router, a computer, etc.), and the detection device 3 can be used to detect whether the box cover 2 is mounted in place on the box body 1. Of course, in other embodiments, the enclosure 10 may be used to mount any other desired boards and/or electronic components, etc. for the electronic device. The utility model discloses increased detection device 3 between box 1 of quick-witted case 10 and case lid 2, whether the assembly that can accurate detection case lid 2 and box 1 targets in place through this detection device 3.

The detection device 3 includes a first detection module 31 disposed on the box 1 and a second detection module 32 disposed on the box cover 2. When the box cover 2 is assembled on the box body 1, the detection device 3 determines whether the box cover 2 is installed in place on the box body 1 according to feedback information generated by the cooperation of the first detection module 31 and the second detection module 32. When the box cover 2 is assembled on the box body 1, the relative positions of the first detection module 31 and the second detection module 32 are different due to different assembling states, and thus the feedback information generated by the first detection module 31 and the second detection module 32 is also different.

Further, the detecting device 3 further includes a signal processing module (not shown) electrically connected to the first detecting module 31 or the second detecting module 32. Correspondingly, the signal processing module may be disposed in the case 1, the case cover 2, or the electronic device having the case 10. The signal processing module can determine whether the box cover 2 and the box body 1 are assembled in place according to feedback information generated by the matching of the first detection module 31 and the second detection module 32. That is, the detection device 3 compares the received feedback information with the preset information when the box cover 2 is installed in place on the box body 1, so as to determine whether the box cover 2 is installed in place on the box body 1.

As shown in fig. 1 to 4, in an embodiment, the first detecting module 31 is a magnet 311, and the second detecting module 32 is a hall chip 314. Of course, in another embodiment, the first detecting module 31 may also be a hall chip 314, and the second detecting module 32 is a magnet 311.

In the embodiment, the hall effect technology is used to realize the in-place detection of the box cover 2. When the magnetic field intensity fed back by the magnetic inductor 321 reaches the preset magnetic induction intensity, the hall chip 314 outputs feedback information for determining that the box cover 2 is installed in place on the box body 1. The preset magnetic induction strength is related to the material and size of the magnet 311 and the maximum magnetic field strength of the magnet 311 and the magnetic inductor 321, and is used as a basis for determining the installation position of the box cover 2 on the box body 1.

As shown in fig. 2, in the process of mounting the cover 2 on the box 1, although the cover 2 is mounted on the box 1, the cover 2 and the box 1 are not mounted in place, the magnet 311 is not aligned with the magnetic sensor 321, and the magnetic sensor 321 cannot acquire the magnetic induction signal of the magnet 11 or the acquired magnetic induction strength does not reach the preset magnetic induction strength. Therefore, the hall chip 314 does not output feedback information that the box cover 2 is installed in place on the box body 1, and the problem that whether the box cover 2 is installed in place on the box body 1 cannot be accurately detected in the prior art is solved.

As shown in fig. 3 and 4, when the magnet 311 faces the magnetic sensor 321, the center line of the magnet 311 coincides with the center line of the magnetic sensor 321, and the center line is the center line (i.e., the dashed line in the figure) of the opposite direction of the magnet 311 and the magnetic sensor 321, and at this time, the hall chip 314 receives the signal of the maximum feedback of the magnetic induction intensity sent by the magnetic sensor 321, and then determines that the case cover 2 is installed in place relative to the case 1.

In addition, the chassis 10 further includes an alarm module (not shown) and/or a display module (not shown) disposed on the box cover 2 or the box body 1, the alarm module and the display module are respectively in communication connection with the hall chip 314, and the hall chip 314 can give a sound prompt through the alarm module or inform a user through a display module in a display mode after determining that the box cover 2 is mounted on the box body 1.

As shown in fig. 1-3 and 5, in another embodiment, the first detection module 31 is an ir transmitter 315 and the second detection module 32 is an ir receiver 325. Of course, in another embodiment, the first detection module 31 is an ir receiver 325 and the second detection module 32 is an ir transmitter 315. In this embodiment, the cover 2 is determined to be mounted in place relative to the housing 1 by feedback information generated when the ir transmitter 315 is opposed to the ir receiver 325.

The detection device 3 further comprises a PCB 316 and a processor 317 disposed on the PCB 316, and the infrared receiver 325 is communicatively connected to the processor 317. When infrared transmitter 315 is aligned with infrared receiver 325, at this time, the center line of infrared transmitter 315 coincides with the center line of infrared receiver 325, infrared receiver 325 can receive the transmission signal of infrared transmitter 315, and then send the transmission signal to processor 317, so that processor 317 outputs feedback information for determining that box cover 2 is installed in place on box 1 according to the transmission signal.

The utility model discloses a quick-witted case mutually supports through first detection module and second detection module to make detection device can judge accurately whether the case lid is installed on the box and targets in place according to feedback information, guarantee the reliability of case lid in situ detection. The problem of prior art scheme can not guarantee reliable on position is solved, a great deal of hidden danger that consequently brings can be avoided.
