Description

Technical Field

[0001] The utility model relates to the technical field of access control equipment, in particular to an access control integrated machine protective cover with a cooling function. Background Art

[0002] In the field of access control systems, with the advancement of technology and the increasing demand for security, the stability and durability of the performance of the integrated access control machine, as a key device integrating identity authentication, control and recording functions, has become the focus of industry attention. The integrated access control machines currently widely used in the market, although they meet basic security needs to a certain extent, often face the problem of overheating of internal electronic components during long-term operation, especially in high temperature environments.

[0003] In the prior art, in order to deal with the high temperature problem of the access control integrated machine, external fan heat dissipation or natural convection heat dissipation is usually adopted. However, these methods have exposed many shortcomings in practical applications. For example, although external fan heat dissipation can effectively reduce the temperature of the device, it increases the complexity and maintenance cost of the device, and the fan noise may affect the use environment; while natural convection heat dissipation is limited by the ambient temperature and the heat dissipation structure design of the device, the effect is limited, and it is difficult to ensure the stable operation of the device under extreme high temperature conditions.

[0004] In addition, the existing protective cover design of the access control integrated machine mostly focuses on physical protection functions such as dust and water resistance, but ignores the improvement of heat dissipation performance. This makes it difficult to effectively discharge the heat in the protective cover in a high temperature environment, exacerbating the temperature rise problem of the internal components of the device, and further affecting the overall performance and service life of the access control integrated machine.

[0005] For example, CN219225572U discloses an access control attendance machine that is easy to maintain, including an attendance machine body and a fingerprint recognition component, a button component and a face recognition display screen component connected to the attendance machine body. The outer sleeve of the attendance machine body is provided with a mounting frame, the cross-section of the side of the mounting frame is U-shaped, and the four corners of the back of the mounting frame are provided with fixing holes. When installing the attendance machine body, this access control attendance machine that is easy to maintain only needs to use bolts to fix the mounting frame to the wall, and then insert the attendance machine body from the top of the mounting frame. When the attendance machine body needs to be disassembled for maintenance, the attendance machine body can be directly pulled out from the top of the mounting frame. The installation and disassembly maintenance process is relatively simple and convenient; the device also only considers the installation, dustproof and waterproof of the equipment, and does not consider the heat dissipation of the equipment.

[0006] In order to solve the above problems and improve the operating stability and durability of the access control integrated machine in a high temperature environment, the present invention proposes a protective cover for the access control integrated machine with a cooling function. The protective cover not only has the physical protection function of the traditional protective cover, but also integrates an efficient cooling system. Through innovative structural design and heat dissipation mechanism, it realizes effective cooling of the internal components of the access control integrated machine, ensuring the long-term stable operation of the equipment.

[0037] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0038] Example 1

[0040] In this embodiment, the protective cover body 1 is hollowed out at the front and back, and the side is trapezoidal, with a larger upper end and a smaller lower end.

[0041] Furthermore, the ventilation holes 2 are fan-shaped structures, the number of which is at least six and which are symmetrically and evenly distributed on both sides of the protective cover body 1 .

[0045] Furthermore, a dustproof net is provided on the protective cover body 1 , covering the ventilation hole 2 , so as to prevent dust from entering the interior of the protective cover body 1 .

[0046] Furthermore, an active cooling device is provided in the protective cover body 1 and is arranged below the cooling fan 5 . The active cooling device is a semiconductor cooling plate, and its cold end is close to the cooling fan 5 , so as to further reduce the temperature of the air blown out by the cooling fan 5 .

[0047] Furthermore, a heat insulating layer is provided inside the protective cover body 1 to thermally isolate the access control integrated machine from the external environment, thereby reducing the influence of the external environment on the internal temperature of the access control integrated machine.

[0048] Furthermore, the temperature control system also includes an alarm module. When the internal temperature exceeds a preset safety threshold, the alarm module is activated and sends out an alarm signal.

[0049] During specific use, when the access control integrated machine starts working, the heat generated inside it is transferred to the heat sink 3 through heat conduction, and the heat on the heat sink 3 is then transferred to the cooling fan 5 of the protective cover body 1 through the heat pipe 4.

[0050] Example 2

[0051] In another preferred embodiment, based on the above-mentioned embodiment 1, an active refrigeration device is further added to improve the cooling effect in a high temperature environment.

[0052] Active cooling device: A semiconductor cooling plate is added under the cooling fan 5.

[0057] Furthermore, the number of the heat dissipation fans 5 is two, which are symmetrically distributed on both sides of the protective cover body 1; the above arrangement makes the heat dissipation effect inside the protective cover body 1 more uniform, and improves the working stability and service life of the equipment. At the same time, the material of the protective cover body 1 is made of high temperature resistant and corrosion resistant materials, which can resist the erosion of the external environment and further protect the safe operation of the internal equipment.

[0060] Furthermore, a dustproof net is provided on the protective cover body 1, covering the ventilation hole 2 to prevent dust from entering the interior of the protective cover body 1; the above arrangement ensures that the equipment operates normally while effectively preventing the intrusion of dust, thereby improving the service life and stability of the equipment; at the same time, the material of the protective cover body 1 is also carefully selected and has excellent corrosion resistance and wear resistance.
