Description

Technical Field

[0001] The utility model belongs to the field of card swiping machine chassis, and in particular relates to an outdoor card swiping machine chassis protective device. Background Art

[0002] The card swiping machine chassis is usually also called the card swiping access control integrated machine. It is an intelligent access control system that uses card swiping recognition to replace keys. It is often used at corporate gates, parking lots, and factory security areas. The card swiping machine chassis is generally installed outdoors. The working environment is relatively harsh and it is inevitably exposed to wind, sun, and rain. However, the electronic equipment inside the card swiping machine chassis requires waterproof, dustproof, and high temperature resistance. Especially in the case of summer sun exposure, it is easy to cause the internal temperature of the chassis to be too high, resulting in equipment crashes, component burnouts, and other faults. On rainy days, there is a risk of leakage and water ingress at the joints of the chassis. Too much dust on the surface of the chassis and dust adhesion inside the chassis may also affect the normal operation of the card swiping machine chassis. Therefore, it is necessary to design a protective device for the card swiping machine chassis. Utility Model Content

[0003] In view of the above situation, the utility model provides an outdoor card swiping machine chassis protection device, which can provide good sun protection, waterproof, dustproof and other protective effects on the chassis.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The invention discloses an outdoor card swiping machine chassis protection device, comprising a card swiping machine chassis, wherein the card swiping machine chassis comprises a card swiping screen and a main chassis, wherein the card swiping screen is mounted on the upper front side of the main chassis, wherein a main control board is arranged in the main chassis, and the card swiping screen is electrically connected to the main control board.

[0006] A canopy is arranged above the card swiping screen. The canopy is a hollow cantilevered eaves structure, which has the functions of top rain protection, dust protection and sun protection. A left diagonal brace and a right diagonal brace are respectively arranged between the bottom of the canopy and the left and right sides of the main box. The left and right diagonal braces are both hollow triangular supports, which have the functions of lateral dust and rain protection. A first air curtain opening and a second air curtain opening are respectively arranged on the lower side of the front edge of the canopy and the lower sides of the left and right diagonal braces, which have the functions of heat insulation, dust protection and rain protection, and at the same time do not affect the normal card swiping recognition of the card swiping screen.

[0007] A ventilation box is provided on the rear side of the main chassis. The hollow cavities of the canopy and the left and right diagonal braces are connected to the ventilation box. A blower is provided at the bottom of the ventilation box. The air inlet of the blower is arranged on the rear side panel of the ventilation box, and the air outlet of the blower blows air toward the upper part of the interior of the ventilation box.

[0008] A semiconductor refrigerator is provided above the air outlet of the blower. The front cooling surface of the semiconductor refrigerator passes through the front side plate of the ventilation box and the rear side plate of the main chassis, and fits tightly with the heating device (such as CPU) of the main control board. A heat sink is provided on the rear heat dissipation surface of the semiconductor refrigerator. The heat sink is located in the ventilation box and placed directly above the air outlet of the blower.

[0009] Furthermore, the semiconductor refrigerator includes a semiconductor cooling plate, the cooling surface of the semiconductor cooling plate is tightly fitted to the heating device of the main control board through thermal conductive silicone grease, and the heat dissipation surface of the semiconductor cooling plate is tightly fitted to the heat sink through thermal conductive silicone grease. The use of thermal conductive silicone grease helps to eliminate thermal conductive gaps and improve thermal conductive efficiency.

[0010] Furthermore, the main box and the ventilation box are both rectangular vertical boxes, the front side plate of the ventilation box is tightly connected to the rear side plate of the main box, and the upper parts of the two are connected to form an installation opening for the semiconductor refrigeration plate to pass through.

[0011] Furthermore, an air filter is provided on the air inlet of the blower. The air filter can be detachably mounted on the rear side panel of the ventilation box to prevent dust and impurities in the outside air from being sucked into the blower and the ventilation box as much as possible. The air filter can be conveniently cleaned regularly to ensure its air permeability.

[0012] The present invention also includes other components that enable it to be used normally, which are all conventional means in the field. In addition, devices or components not limited in the present invention, such as semiconductor refrigeration plates, heat sinks, card swiping screens of card swiping machine chassis, main control boards and circuit components thereof, etc., all adopt existing technologies in the field.

[0013] The beneficial effects of the utility model are as follows:

[0014] The outdoor card swiping machine chassis protection device provided by the utility model adds protection measures such as a ventilation box, a protective canopy and an airflow curtain on the basis of the existing card swiping machine chassis, which can provide good protection for the outdoor card swiping machine chassis against rain, sun and dust, and cools down the heating components inside the card swiping machine chassis through a semiconductor refrigerator, which can effectively prevent the card swiping machine chassis from being stuck due to high temperature, freezing and component burnout, reduce the failure rate of the card swiping machine chassis equipment, increase the life of the equipment, and ensure the reliable operation of the card swiping machine chassis.
