Description

Technical Field

[0001] This utility model belongs to the field of attendance gate technology, and specifically relates to a quick-release heat dissipation structure for a dynamic face recognition module of an attendance gate. Background Technology

[0002] The existing quick-release heat dissipation structure of dynamic facial recognition modules for attendance gates has certain drawbacks when using bolt fixing, mainly manifested in complex disassembly, low maintenance efficiency, and potential equipment damage risks. The core issue is that bolt fixing requires tools, and after long-term use, it is prone to corrosion, jamming, or becoming too tight, making it difficult to loosen. This leads to increased module replacement or repair time, impacting work efficiency. Such shortcomings usually stem from insufficient consideration of ease of maintenance during the design phase, or from sacrificing disassembly for the sake of equipment stability.

[0003] To address the aforementioned issues, conventional solutions include regularly applying rust inhibitors to reduce bolt corrosion, using specialized tools to improve disassembly efficiency, or replacing traditional bolts with quick-locking mechanisms. However, these measures also have drawbacks. For example, rust inhibitors may attract dust, exacerbating bolt jamming; specialized tools increase maintenance costs and operational complexity; and replacing bolts with quick-locking mechanisms may result in insufficient structural strength, affecting the module's operational stability. Therefore, we aim to design a novel quick-release heat dissipation structure for the dynamic facial recognition module of the attendance gate to solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-release heat dissipation structure for a dynamic face recognition module of an attendance gate, thereby solving the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a quick-release heat dissipation structure for a dynamic face recognition module of an attendance gate, comprising: an attendance machine body, wherein a heat dissipation component for dissipating heat from the face recognition module body is installed inside the attendance machine body, and a module frame for mounting the face recognition module body is provided inside the right side of the attendance machine body, wherein the face recognition module body is mounted on the upper side of the module frame.

[0006] The heat dissipation assembly includes a mounting frame, with multiple elastic elements evenly spaced at the upper end of the mounting frame. A claw is integrally provided on the front and rear sides of the mounting frame, and a guide plate is integrally provided on the left and right sides of the mounting frame. A fan is installed in the middle of the mounting frame.

[0007] In a preferred embodiment, a maintenance plate is installed on the right surface of the attendance machine body. Each of the four corners of the maintenance plate is threaded with a screw knob for fixing the maintenance plate. An air inlet is provided on the upper side of the maintenance plate for air intake, and an air outlet is provided on the lower side of the maintenance plate for air exhaust. By providing a maintenance plate that is easy to disassemble, it is convenient to quickly disassemble the heat dissipation components and to repair the remaining components inside the attendance machine body.

[0008] In a preferred embodiment, the module frame has a vent opening at the rear of the upper end, and a snap-fit ​​groove is provided on the front and rear sides of the vent edge in a centrally symmetrical manner. A guide groove is provided on the left and right sides of the vent edge in a centrally symmetrical manner.

[0009] In a preferred embodiment, the right end of the card slot has a top-view width greater than the left end, and the width of the right end of the card slot matches the maximum width of the upper end of the card claw.

[0010] In a preferred embodiment, the upper end of the claw is provided with a snap-fit ​​protrusion facing the axis of the mounting frame for abutting against the upper surface of the module frame to clamp and fix the mounting frame. The cross-sectional structure of the claw is an inverted L-shaped structure.

[0011] In a preferred embodiment, the height of the elastic element is greater than the height of the chuck, and the elastic element includes a guide rod, with a limit ring provided at the upper third position of the guide rod.

[0012] In a preferred embodiment, the upper side of the limiting ring is fixedly connected to the lower end of the spring, the upper end of the guide rod is slidably installed inside the telescopic cap, and the portion of the guide rod located below the limiting ring is slidably connected to the bottom of the telescopic cap. Both the limiting ring and the spring are placed inside the telescopic cap, and the outer wall of the limiting ring is slidably connected to the inner wall of the telescopic cap. In actual use, the elastic element can work with the claws to fix the mounting frame on the module frame, thereby enabling the heat dissipation components to be quickly installed and removed.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting air holes and card slots on the module frame of the attendance machine body, in actual use, it can be used to install heat dissipation components, so that it can dissipate heat from the face recognition module body on the upper side of the module frame. External air enters through the air inlet to cool the face recognition module body, and then is discharged through the air outlet under the suction of the heat dissipation components. A maintenance plate that is easy to disassemble is set on the right side of the attendance machine body, which facilitates the quick disassembly of the heat dissipation components and the subsequent maintenance of other components inside the attendance machine body.

[0014] 2. Regarding the heat dissipation component's design, in practical use, if quick disassembly of the heat dissipation component is required, the user only needs to rotate the mounting frame counterclockwise. When the two claws on the mounting frame reach the wider end of the engagement slot, the two claws quickly disengage from the engagement slot under the restoring potential energy of the elastic element. At the same time, the two guide plates also disengage from the guide slots, thus achieving the purpose of quick disassembly of the heat dissipation component. It does not use traditional bolts or screws for fixing; quick disassembly can be completed simply by rotation, which helps reduce the difficulty of disassembling the heat dissipation component and solves the problem of difficult disassembly caused by bolt fixing. If installation is required, the mounting frame... The two claws rotate at the wider end of the two locking slots, and then the mounting frame is pushed up. At this time, the two claws pass through the two locking slots. At the same time, multiple elastic elements are limited and compressed by the lower side of the module frame. Then, the mounting frame is rotated clockwise. After the two claws reach the maximum rotation stroke, they are released. At this time, under the action of the elastic elements, the mounting frame moves down as a whole, and the protrusions on the claws engage with the upper side of the module frame and are locked under the action of the elastic elements. This allows the entire heat dissipation component to be stably installed on the module frame, which solves the problem that some existing improvement solutions may have insufficient structural strength and affect the stability of module operation if they are replaced with a quick-locking mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As the first embodiment of this utility model:

[0025] Please see Figures 1 to 5 A quick-release heat dissipation structure for a dynamic face recognition module of an attendance gate includes: an attendance machine body 100, a heat dissipation component 200 for dissipating heat from a face recognition module body 110 installed inside the attendance machine body 100, a module frame 130 for mounting the face recognition module body 110 inside the right side of the attendance machine body 100, and a face recognition module body 110 mounted on the upper side of the module frame 130.

[0026] The heat dissipation assembly 200 includes a mounting frame 210. Multiple elastic elements 220 are evenly spaced on the upper end of the mounting frame 210. A claw 230 is integrally provided on the front and rear sides of the mounting frame 210. A guide plate 250 is integrally provided on the left and right sides of the mounting frame 210. A fan 240 is installed in the middle of the mounting frame 210.

[0027] A maintenance plate 120 is installed on the right surface of the attendance machine body 100. Each of the four corners of the maintenance plate 120 has a screw knob 122 for fixing the maintenance plate 120. An air inlet 121 is provided on the upper side of the maintenance plate 120 for air intake, and an air outlet 123 is provided on the lower side of the maintenance plate 120 for air exhaust. By setting up a maintenance plate 120 that is easy to disassemble, it is convenient to quickly disassemble the heat dissipation component 200 and to inspect other components inside the attendance machine body 100.

[0028] A vent 133 is provided on the upper rear side of the module frame 130. A snap-fit ​​groove 131 is provided on the front and rear sides of the vent 133 in a centrally symmetrical manner. A guide groove 132 is provided on the left and right sides of the vent 133 in a centrally symmetrical manner.

[0029] Specifically, by setting air vents 133 and card slots 131 on the module frame 130 of the attendance machine body 100, in actual use, these can be used to install the heat dissipation component 200, so that it can dissipate heat from the face recognition module body 110 on the upper side of the module frame 130. External air enters through the air inlet 121 to cool the face recognition module body 110, and then is discharged through the air outlet 123 under the suction of the heat dissipation component 200. A maintenance plate 120 that is easy to disassemble is set on the right side of the attendance machine body 100, which facilitates the quick disassembly of the heat dissipation component 200 and the subsequent maintenance of other components inside the attendance machine body 100.

[0030] As a second embodiment of this utility model:

[0031] Please see Figures 1 to 5 The right end of the card slot 131 has a top-view width that is greater than the top-view width of the left end, and the width of the right end of the card slot 131 matches the maximum width of the upper end of the claw 230.

[0032] The upper end of the claw 230 is provided with a snap-fit ​​boss in the direction of the axis of the mounting frame 210 for abutting against the upper surface of the module frame 130 to clamp and fix the mounting frame 210. The cross-sectional structure of the claw 230 is an inverted L-shaped structure.

[0033] The height of the elastic element 220 is greater than the height of the claw 230. The elastic element 220 includes a guide rod 223, and a limit ring 222 is provided at the upper third position of the guide rod 223.

[0034] The upper side of the limiting ring 222 is fixedly connected to the lower end of the spring. The upper end of the guide rod 223 is slidably installed inside the telescopic cap 221. The part of the guide rod 223 located below the limiting ring 222 is slidably connected to the bottom of the telescopic cap 221. Both the limiting ring 222 and the spring are placed inside the telescopic cap 221. The outer wall of the limiting ring 222 is slidably connected to the inner wall of the telescopic cap 221. In actual use, the elastic element 220 can work with the claw 230 to fix the mounting frame 210 on the module frame 130, thereby allowing the heat dissipation component 200 to be quickly installed and removed.

[0035] Based on the first embodiment described above, in actual use, if it is necessary to quickly disassemble the heat dissipation component 200, the user only needs to rotate the mounting frame 210 counterclockwise. When the two claws 230 on the mounting frame 210 reach the wider end of the locking groove 131, under the restoring potential energy of the elastic element 220, the two claws 230 quickly disengage from the locking groove 131. At the same time, the two guide plates 250 also disengage from the guide groove 132, thereby achieving the purpose of quickly disassembling the heat dissipation component 200. It does not use traditional bolts or screws for fixing, and can be quickly disassembled simply by rotating, which helps to reduce the difficulty of disassembling the heat dissipation component 200 and solves the problem of disassembly difficulties caused by using bolts for fixing.

[0036] When installation is required, rotate the two claws 230 on the mounting frame 210 to the wider end of the two locking slots 131, and then push the mounting frame 210 upward. At this time, the two claws 230 penetrate the two locking slots 131. At the same time, multiple elastic elements 220 are limited and compressed by the lower side of the module frame 130. Then rotate the mounting frame 210 clockwise. After the two claws 230 reach their maximum rotation stroke, they are released. At this time, under the action of the elastic elements 220, the mounting frame 210 moves down as a whole, and the protrusion on the claws 230 engages with the upper side of the module frame 130 and is locked under the action of the elastic elements 220. This allows the entire heat dissipation assembly 200 to be stably installed on the module frame 130, solving the problem that some existing improvement solutions may result in insufficient structural strength and affect the stability of module operation if the quick-locking mechanism is replaced.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
