Referring to fig. 1 to 4 together, a description will now be given of the anti-occupancy desk lamp according to the embodiment of the present invention. In one embodiment, the anti-occupancy desk lamp comprises a lamp holder 1, a lamp holder 2, a locking mechanism 3, a resetting mechanism 4 and a data processing device 5. The lamp holder 2 is rotatably connected with the lamp holder 1, the lamp holder 1 is used for being fixed on a desktop, the lamp holder 2 is provided with a light source assembly 21, and the light source assembly 21 rotates along with the rotation of the lamp holder 2. When the lamp holder 2 rotates to be close to the desktop relative to the lamp holder 1, the lamp holder 2 is in a closed position, the lamp holder 2 and the light source component 21 occupy the space of the desktop, and other people cannot use articles to occupy the seat. When the lamp holder 2 rotates to a position far away from the desk surface relative to the lamp holder 1, the lamp holder 2 is in a use position, and a user can normally use the desk lamp and a seat with the desk lamp. The locking mechanism 3 is used for locking the lamp holder 2 at a closing position, and the resetting mechanism 4 is used for enabling the lamp holder 2 to rotate from the closing position to a using position. Data processing device 5 and locking mechanism 3 and the equal electric connection of light source subassembly 21, data processing device 5 is used for gathering and storing user's desk lamp service data to use data control locking mechanism 3 and light source subassembly 21 through user's desk lamp. The desk lamp use data comprise information such as time of each user occupying the desk lamp and time period of actually using the desk lamp, the time of the user occupying the desk lamp can be acquired and stored in a terminal or webpage appointment, and the time period of actually using the desk lamp can be acquired through the working state of the locking mechanism 3. The locking mechanism 3 locks the lamp holder 2 when working, namely, the lamp holder 2 is in a closed position and the desk lamp is not used; the locking mechanism 3 releases the lamp holder 2 when not in operation, namely, the lamp holder 2 is in the use position, and the desk lamp is in use. Thus, the data control device obtains the time period for actually using the table lamp according to the state of the locking mechanism 3.

When a user needs to use the desk lamp, a seat with a seat occupation prevention desk lamp can be reserved through a terminal or a webpage, then the seat arrives at the seat within a reserved time period, and the desk lamp is started through the terminal, an identity card or a two-dimensional code on the desk lamp; or directly go to the library and look for the seat, start the desk lamp through two-dimensional code on terminal, identity card or the desk lamp etc.. The locking mechanism 3 is unlocked when the desk lamp is started, the locking mechanism 3 releases the lamp holder 2, the resetting mechanism 4 enables the lamp holder 2 to rotate to the use position and lights the light source assembly 21, and the data processing device 5 obtains the use time of the desk lamp and the information of an operation user. When leaving the seat, the lamp holder 2 is rotated manually to rotate to the closed position, the locking mechanism 3 locks the lamp holder 2, the data processing device 5 obtains the time information of the desk lamp switched to the unused state, and the light source assembly 21 is controlled to be closed. The data processing device 5 records the acquired use data of the desk lamp, acquires actual use data of the desk lamp of the user and occupied time data of the desk lamp when the user next reserves a seat or directly starts the desk lamp, and judges whether the seat can be reserved. If the user starts the desk lamp in the appointed time period in time, or leaves the seat and does not close the desk lamp, when the actual service time of the desk lamp is not matched with the occupied desk lamp time of the user, the next seat appointment can be influenced, so that the seat use habit of the user can be standardized, and the seat occupation phenomenon is avoided.

According to the anti-occupation desk lamp provided by the embodiment of the invention, the lamp holder 1 is fixed on a desktop, the lamp holder 2 is rotatably connected with the lamp holder 1, the lamp holder 2 is provided with a use position far away from the desktop and a closed position close to the desktop, the lamp holder 2 can be manually rotated to the closed position and locked by the locking mechanism 3, and when the locking mechanism 3 is unlocked, the lamp holder 2 is driven by the resetting mechanism 4 to rotate to the use position. The desk lamp use data of the user are collected through the states of the locking mechanism 3 and the reset mechanism 4 of the data processing device 5, when the user uses the desk lamp next time, the data processing device judges whether the user is allowed to use the desk lamp or not by comparing the time of actually using the desk lamp by the user and the time occupied by the desk lamp, so that the user is prompted to manually rotate the lamp holder 2 to a closed position when leaving the seat, the space of a desktop is occupied, thereby preventing other people from using books, schoolbag and the like to occupy the seat, and realizing the maximized utilization of library seat resources.

Referring to fig. 6 and 7, fig. 6 and 7 are schematic diagrams of two circuits of the anti-occupancy desk lamp. The data processing device can be selected as an MCU of the model NRF52832 or STM32F103C8T6, the MCU is electrically connected with a driving circuit of the locking mechanism through pins M1 and M2, and the MCU is electrically connected with the light source assembly 21 through a PWM pin.

At the same time, the data processing device 5 records the information that the electronic lock 31 locks the hook 32, i.e. the lamp holder 2 is in the closed position.

In one embodiment of the locking mechanism 3, the electronic lock 31 includes a driving portion 311 and a lock lever 312, and the lock lever 312 is pushed by the driving portion 311. When the electronic lock 31 is in the locking state, the lock bar 312 is pushed out by the driving portion 311, so that the lock bar 312 stops the hook 32, and the lamp holder 2 is locked in the closing position. The structure of the hook 32 is not limited herein, and may be stopped by the lock bar 312. Alternatively, the pushing direction of the lock rod 312 is parallel to the rotation axis of the lamp holder 2, so that the pushing direction of the lock rod 312 is perpendicular to the rotation tangential direction of the hook 32, so that the lock rod 312 can effectively lock the hook 32. The electronic lock 31 may be selected as an electromagnetic lock.

In another embodiment of the locking mechanism 3, the locking mechanism 3 only comprises the hook 32 and the electronic lock 31, and the electronic lock 31 is electrically connected with the data processing device 5.

After the lamp holder 2 rotates to the closed position, the lock rod 312 automatically rebounds to lock the hook 32. In this embodiment, the electronic lock 31 is normally in an extended state of the lock bar 312, the lock bar 312 sends a trigger signal to the data processing device 5 when being retracted by the hook 32, and the data processing device 5 records the time when the lamp holder 2 rotates to the closed position according to the sending time of the trigger signal. Meanwhile, a guide inclined surface 3121 matched with the hook 32 is arranged on one side of the lock rod 312 back to the table top, and the guide inclined surface 3121 is convenient for pushing the lock rod 312 back when the hook 32 rotates to the closing position.
