At the same time, it can realize real-time data uploading, improving attendance efficiency and accuracy.

[0003] A search revealed that Chinese patent CN210666890U discloses "an outdoor time attendance machine, comprising a time attendance machine shell, a lifting column, and a time attendance machine mounting base; the time attendance machine shell is mounted on the upper end of the lifting column; the lower end of the lifting column is connected to the time attendance machine mounting base; the time attendance machine shell includes a movable upper cover and a fixed lower cover; one side of the movable upper cover is connected to the fixed lower cover via a hinge shaft, and the other side of the movable upper cover is closed to the fixed lower cover via a buckle, forming an installation cavity for accommodating an Android motherboard; the movable upper cover opens outward about the hinge shaft as the rotation axis; a camera, an LCD screen, and a card reader are arranged sequentially from top to bottom on the upper surface of the movable upper cover; a sealing strip is provided at the joint between the movable upper cover and the fixed lower cover. This utility model, by providing a sealing strip at the joint between the movable upper cover and the fixed lower cover, and using sheet metal material for the time attendance machine shell, can prevent rainwater from entering the device, thus having a rainproof function and being suitable for outdoor time attendance." However, it still has the following drawbacks:

[0004] (1) The complex outdoor environment will accelerate the aging of the sealing strip. The attendance machine is sealed only with sealing strip. Dust and other objects can easily enter the attendance machine and damage the electronic components. In addition, the attendance machine is not connected to the performance appraisal system. The attendance data cannot be automatically converted into specific scores or evaluation criteria in the performance appraisal. It requires manual input and calculation, which increases the workload and is prone to data input errors.

[0005] (2) During operation, the Android motherboard and other electronic components of the outdoor time attendance machine generate heat.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment proposes an outdoor attendance machine with a protective cover for attendance performance management, including a housing 1. An attendance mechanism 2 for access control and recording personnel entry and exit is provided inside the housing 1. A heat dissipation component 3 for promoting air circulation inside the housing 1 is provided on one side of the housing 1.

[0035] like Figure 4 , Figure 5 and Figure 6As shown, the attendance system 2 includes a camera 201 mounted on the top side wall of the housing 1. The camera 201 is used to capture facial images of the attendance personnel to achieve facial recognition attendance functionality.

[0037] like Figure 6 As shown, the protective assembly 210 includes a slide groove 2101 fixedly connected to two side walls opposite to the housing 1. A metal layer 2102 is fixedly connected to the top of the slide groove 2101. A slider 2103 is slidably connected to the outer wall of the slide groove 2101. The slide groove 2101 provides a track for the slider 2103 to slide, ensuring that the slider 2103 can slide in a predetermined direction. A protective cover 2104 is fixedly connected to one side of the top of the slider 2103, and a magnetic block 2105 is fixedly connected to the other side of the top of the slider 2103. The metal layer 2102 and the magnetic block 2105 cooperate with each other to firmly fix the protective cover 2104 to the housing 1. The protective cover 2104 provides physical protection for the housing 1, extending the service life of the equipment. When attendance is required, Manually push the protective cover 2104. The protective cover 2104 drives the slider 2103 to slide along the slide groove 2101 towards the top of the housing 1. When the slider 2103 slides to the top of the slide groove 2101, the magnetic block 2105 and the metal layer 2102 approach each other and generate magnetic attraction. The slider 2103 is tightly attracted to the top of the slide groove 2101, thereby making the protective cover 2104 firmly fixed on the housing 1, exposing the operating area of ​​the attendance machine, which is convenient for employees to perform attendance operations. After attendance is completed, slide the protective cover 2104 to the bottom. The metal layer 2102 moves away from the attraction range of the magnetic block 2105 and loses its magnetic force. The slider 2103 falls naturally to the bottom of the slide groove 2101, achieving effective protection for the housing 1 and preventing dust from entering the interior of the housing 1.

[0038] like Figure 7 As shown, the heat dissipation assembly 3 includes a heat dissipation slot 301 located on the side of the housing away from the display screen 202. The heat dissipation slot 301 provides installation and airflow space. Several ventilation holes 302 are provided on the side wall of the heat dissipation slot 301, allowing outside air to enter the heat dissipation slot 301, providing fresh air for the heat dissipation process and enhancing the heat dissipation effect. A rectangular plate 303 is fixedly connected to the inner wall of the heat dissipation slot 301. A micro motor 304 is bolted to the side wall of the rectangular plate 303. The rectangular plate 303 provides a mounting base for the micro motor 304, preventing damage due to... When vibration causes displacement or loosening, a rotating rod 305 is fixedly connected to the output end of the micro motor 304. The micro motor 304 provides a power source to drive the rotating rod 305 to rotate. A fan blade 306 is welded to the side wall of the rotating rod 305. The rotating rod 305 transmits power, transferring the rotational power generated by the micro motor 304 to the fan blade 306. A battery 307 is installed at the bottom of the heat dissipation slot 301. A temperature and humidity sensor is installed on the inner wall of the housing 1. The temperature and humidity sensor is electrically connected to the micro motor 304 through a controller. The battery 307 is connected to the temperature and humidity sensor. A humidity sensor is electrically connected and detects the temperature and humidity inside the housing 1. When the temperature and humidity are too high, the controller will activate the micro motor 304. Heat dissipation holes 308 are provided on the side wall of the housing 1, serving as channels for heat dissipation and allowing the heat inside the housing 1 to dissipate in a timely manner. During operation, heat accumulates inside the housing 1, causing the internal temperature to rise. At this point, the controller activates the micro motor 304, which drives the rotating rod 305 and the fan blade 306 to rotate. When the fan blades 306 rotate at high speed, the airflow speed in the heat sink 301 will increase. Outside air enters the housing 1 through the ventilation holes 302 and comes into contact with the surface of the motherboard 208 and wireless network module 209 inside the housing 1, absorbing their surface heat. The air temperature rises after absorbing heat. Under the continuous push of the fan blades 306, it is discharged from the heat sink 308 on the side wall of the housing 1 into the external environment of the attendance machine, ensuring that the heat inside the housing 1 can be dissipated in time, keeping the internal temperature within a reasonable range, and ensuring the stable operation and performance of the attendance machine.

[0039] like Figure 1 and Figure 2 As shown, a support base 4 is fixedly connected to the bottom of the housing 1. A threaded groove 5 is provided on the bottom of the support base 4. The support base 4 provides stable support for the housing 1, and the threaded groove 5 provides an interface for the installation of the housing 1. The attendance machine can choose the appropriate installation method and position according to different installation scenarios and needs.

[0040] like Figure 1 and Figure 2As shown, a telescopic rod 6 is provided at the bottom of the support base 4. A base 7 is fixedly connected to the bottom of the telescopic rod 6, and a threaded component 8 is fixedly connected to the top of the telescopic rod 6. The threaded component 8 is compatible with the threaded groove 5. By adjusting the length of the telescopic rod 6, the height of the attendance machine can be easily adjusted to adapt to various installation environments. The compatibility of the threaded component 8 with the threaded groove 5 at the bottom of the support base 4 facilitates the connection and disassembly of the telescopic rod 6 and the support base 4, improving installation and maintenance convenience. The base 7 is made of steel plate, and through holes are provided at each of the four corners of the base 7.

[0041] like Figure 3 As shown, a fixing member 9 is fixedly connected to the side wall of the housing 1 away from the display screen 202. A filter screen 10 is slidably connected to the side wall of the fixing member 9. Both the filter screen 10 and the side wall of the fixing member 9 are provided with reserved holes 11. A fixing bolt 12 is threadedly connected to the inner wall of the reserved hole 11. The fixing member 9 provides the installation position and support for the filter screen 10. The filter screen 10 can effectively prevent dust from entering the time attendance machine when the fan blade 306 rotates, keep the internal components clean, and extend the service life of the time attendance machine. The cooperation of the reserved hole 11 and the fixing bolt 12 can firmly fix the filter screen 10 to the fixing member 9. By loosening the fixing bolt 12, the filter screen 10 can be easily removed from the fixing member 9, improving the convenience of operation.

[0042] The filter screen 10 is installed on the housing 1 by means of fasteners 9. There are four fasteners 9, which are fixed at the four corners of the heat dissipation groove 301 respectively.

[0043] like Figure 3 As shown, a dustproof mesh 13 is fixedly connected to the inner wall of the heat dissipation hole 308. The dustproof mesh 13 is made of aluminum alloy. The aluminum alloy dustproof mesh 13 can effectively block dust particles in the air from entering the time attendance machine. The aluminum alloy material has good corrosion resistance and can be used outdoors for a long time without rusting or being damaged, thus ensuring the service life of the dustproof mesh 13.

[0044] Specifically, when using this outdoor attendance machine with a protective cover for attendance management: When attendance is required, manually push the protective cover 2104. The protective cover 2104 causes the slider 2103 to slide along the groove 2101 towards the top of the housing 1. When the slider 2103 reaches the top of the groove 2101, the magnetic block 2105 and the metal layer 2102 approach each other, generating a magnetic attraction. The slider 2103 is then firmly attached to the top of the groove 2101, thus securing the protective cover 2104 firmly to the housing 1. This exposes the operating area of ​​the attendance machine, facilitating attendance operations for employees. Then, the attendance personnel... When an employee stands in front of the attendance machine, the camera 201 on the top side wall of the casing 1 captures an image of the employee's face. The camera 201 transmits the captured image data to the motherboard 208. After receiving the attendance data, the motherboard 208 processes and verifies it. The processed and verified attendance data is then transmitted by the motherboard 208 to the wireless network module 209. The wireless network module 209 sends the attendance data to an external performance appraisal system via a wireless network. Upon receiving the attendance data, the performance appraisal system performs further statistical analysis to facilitate subsequent processing (e.g., ...). Figure 4 , Figure 5 and Figure 6 As shown), during operation, heat accumulates continuously inside the casing 1, causing the internal temperature to rise. When the temperature sensor detects that the temperature is too high, it will control the micro motor 304 to turn on the power. The micro motor 304 drives the rotating rod 305 to rotate, which increases the airflow speed in the heat dissipation slot 301. Outside air enters the casing 1 through the ventilation hole 302 and comes into contact with the surface of the main board 208 and wireless network module 209 inside the casing 1, absorbing their surface heat. The air temperature rises after absorbing heat, and under the continuous push of the fan blades 306, it is discharged from the heat dissipation hole 308 on the side wall of the casing 1 into the external environment of the time attendance machine (such as...). Figure 7 (As shown).

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
