Description

Technical Field

[0001] This utility model belongs to the field of anti-interference technology for self-service terminal main control machines, and particularly relates to an anti-interference device for self-service terminal main control machines. Background Technology

[0002] The main control unit of the self-service terminal is the core component of the intelligent self-service terminal, responsible for processing various instructions and data.

[0003] The main control unit of a self-service terminal is similar to the CPU of a computer, playing a crucial role in the self-service terminal equipment. It is the "brain" of the self-service terminal equipment, controlling the operation of multiple intelligent modules inside the equipment, such as the withdrawal module and the deposit module, ensuring that the self-service terminal equipment can provide services to users normally and efficiently.

[0004] In the prior art, Chinese utility model patent CN221768423U discloses an anti-interference protective structure for an EEG signal processing terminal, including a protective component and an adjustment component. The protective component includes a protective shell, a shielding shell, and a signal processing body, with the shielding shell disposed inside the protective shell and the signal processing body disposed inside the shielding shell. The adjustment component further enhances the functionality of the device. The adjustment component allows for adjustment of the signal processing body's position. When needed, the signal processing body can be rotated out of the protective shell and fixed in its position, while also facilitating its return to the protective shell, thus improving protection. The fixing component secures the signal processing body, allowing for easy removal during maintenance, improving convenience.

[0005] In existing technologies, by setting an adjustment component, the signal processing unit can be rotated out of the protective shell and fixed in its position. The fixing component improves the convenience of maintenance, but there are still some shortcomings in overall use:

[0006] First, in order to ensure the shielding of electromagnetic radiation, existing shielding covers often cannot have holes made on the outer end face or inside for heat dissipation. As a result, the main control unit inside is prone to heat accumulation, leading to a decrease in performance. At the same time, the heat dissipation holes are not protected, allowing external dust to easily enter the interior of the shielding cover and reduce the service life of the equipment.

[0007] Secondly, when the shielding cover is impacted, the internal main control unit is not equipped with a shock absorption device, which causes the main control unit to be bumped and easily damages the internal electrical components. Summary of the Invention

[0008] This invention addresses the technical problems of heat buildup in the internally enclosed main control unit, leading to decreased performance, and the lack of shock absorption devices in the main control unit, which can easily damage internal electrical components. It provides an anti-interference device for the main control unit of a self-service terminal.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference device for a self-service terminal main control unit, comprising a mounting plate and a main control unit body. A cast aluminum housing is fixedly mounted on the front surface of the mounting plate. An anti-interference mechanism is provided inside the cast aluminum housing. The main control unit body is disposed inside the anti-interference mechanism, thereby reducing electromagnetic interference to the main control unit body.

[0010] A perforated plate is fixedly installed inside the cast aluminum shell cavity and above the anti-interference mechanism. A telescopic heat-conducting column is fixedly installed on the lower surface of the perforated plate, and a heat-conducting plate that abuts against the upper surface of the anti-interference mechanism is fixedly installed at the bottom end of the telescopic heat-conducting column.

[0011] A limiting post is fixedly installed on the upper surface of the perforated plate. A thermal expansion airbag is fixedly installed inside the limiting post. The lower surface of the thermal expansion airbag is in contact with the telescopic heat-conducting post. A fixing plate is fixedly installed in the inner cavity of the cast aluminum shell above the perforated plate. A switch is slidably installed on the lower surface of the fixing plate. A heat dissipation mechanism is provided on the upper surface of the fixing plate for rapid heat dissipation of the main control unit.

[0012] By using heat-conducting columns, heat-conducting plates, expansion airbags, and switches, the heat dissipation mechanism can dissipate heat from the main control unit in a timely manner, preventing heat buildup and its impact on the main control unit, and greatly improving the service life of the main control unit.

[0013] In the anti-interference device of the self-service terminal main control machine mentioned above, the heat dissipation mechanism includes a fan fixedly installed inside the fixed plate, a heat dissipation window fixedly installed on the upper surface of the cast aluminum shell, and a cover plate slidably installed on the upper surface of the heat dissipation window.

[0014] The cover plate can be opened when heat dissipation is needed and closed when heat dissipation stops, which can prevent external dust from entering the interior of the cast aluminum housing and causing negative impacts on the main controller.

[0015] In the anti-interference device of the self-service terminal main control machine mentioned above, two symmetrically arranged electric telescopic rods are fixedly installed on the upper surface of the fixed plate, and the output end of the electric telescopic rods is fixed to the lower surface of the cover plate.

[0016] In the anti-interference device of the self-service terminal main control machine mentioned above, a third spring is fixedly installed between the lower surface of the fixing plate and the switch, and the switch controls the fan and the electric telescopic rod.

[0017] The use of a third spring allows the switch to be reset, enabling automatic heat dissipation without the need for a fan to run continuously, thus reducing costs.

[0018] In the aforementioned anti-interference device for the self-service terminal main control unit, the anti-interference mechanism includes a U-shaped electromagnetic shielding absorbing plate fixedly installed in the inner cavity of the cast aluminum housing. The main control unit body is fixedly installed inside the electromagnetic shielding absorbing plate. A door is hinged to the front surface of the cast aluminum housing. A first absorbing sheet that works in conjunction with the main control unit body is fixedly installed on the inner surface of the door. Second absorbing sheets are slidably installed on both sides of the main control unit body.

[0019] By using electromagnetic shielding absorbing plates, the first absorbing sheet, and the second absorbing sheet, the main control unit can be further shielded, preventing external electromagnetic signals from interfering with the main control unit and ensuring its normal operation.

[0020] In the anti-interference device of the self-service terminal main control machine mentioned above, knobs are threaded on both sides of the cast aluminum housing, and a rubber pad is rotatably installed at one end of the knob located inside the cast aluminum housing. The second wave-absorbing sheet is fixedly installed on the side of the rubber pad.

[0021] The use of rubber pads can reduce shock in the left and right directions of the main controller, protecting it from impacts and improving its performance.

[0022] In the anti-interference device of the self-service terminal main control machine mentioned above, a support plate is fixedly installed in the inner cavity of the cast aluminum shell and below the electromagnetic shielding absorbing plate. A first spring is fixedly installed between the upper surface of the support plate and the lower surface of the electromagnetic shielding absorbing plate. A second spring, which is penetrated by the telescopic heat-conducting column, is fixedly installed between the upper surface of the heat-conducting plate and the lower surface of the hollow plate.

[0023] The use of the first and second springs further improves the vibration damping effect of the main control unit.

[0024] In the anti-interference device of the self-service terminal main control machine mentioned above, a through groove is provided on the front surface of the door, and a dustproof net is fixedly installed inside the through groove.

[0025] By using a dust filter, external dust is prevented from entering the interior of the cast aluminum housing, thus extending the service life of the main controller.

[0026] In summary, compared with the prior art, the anti-interference device for the main control machine of the self-service terminal provided by this utility model has the following beneficial effects:

[0027] 1. This utility model, through the construction of a cast aluminum shell, an electromagnetic shielding absorbing plate, a first absorbing sheet, and a second absorbing sheet, can effectively reduce the intensity of electromagnetic interference and improve the stability of the equipment.

[0028] 2. This utility model, through the setting of heat-conducting plate, telescopic heat-conducting column, thermal expansion airbag, fan, electric telescopic rod and cover plate, can automatically and quickly dissipate heat from the main control unit body, reduce the cost of use, and at the same time prevent external dust from entering the interior of the shielding cover, affecting the working effect of the main control unit, and greatly improve the service life of the main control unit.

[0029] 3. By incorporating a first spring, a rubber pad, and a second spring, this utility model can buffer and dampen the main controller when it is impacted, ensuring its stability and improving its performance. Attached Figure Description

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0037] refer to Figure 1 and Figure 2An anti-interference device for a self-service terminal main control machine includes a mounting plate 10 and a main control machine body 35. A cast aluminum shell 11 is fixedly mounted on the front surface of the mounting plate 10. The cast aluminum shell 11 first shields the main control machine body 35. The cast aluminum shell 11 is fixedly mounted on the device being used by the mounting plate 10. A door 12 is hinged to the front surface of the cast aluminum shell 11. Opening the door 12 allows the main control machine body 35 to be fixedly mounted inside the mounting plate 10. A heat dissipation window 13 is fixedly mounted on the upper surface of the cast aluminum shell 11 for heat dissipation and cooling of the main control machine body 35. Example

[0038] refer to Figure 1 and Figure 2 A U-shaped electromagnetic shielding absorbing plate 14 is fixedly installed inside the cavity of the cast aluminum housing 11. The main control unit 35 is fixedly installed inside the electromagnetic shielding absorbing plate 14. A support plate 16 is fixedly installed inside the cavity of the cast aluminum housing 11 and below the electromagnetic shielding absorbing plate 14. A first spring 17 is fixedly installed between the upper surface of the support plate 16 and the lower surface of the electromagnetic shielding absorbing plate 14. A perforated plate 21 is fixedly installed inside the cavity of the cast aluminum housing 11 and above the electromagnetic shielding absorbing plate 14. A heat-conducting plate 23 is fixedly installed between the lower surface of the perforated plate 21 and the upper surface of the electromagnetic shielding absorbing plate 14. Both the support plate 16 and the perforated plate 21 are made of damping material. In use, the support plate 16, the first spring 17, the perforated plate 21, and the second spring 22 can buffer and dampen the main control unit 35 in the vertical direction, preventing damage to the main control unit 35 when it is impacted and improving the service life of the equipment. Example

[0039] refer to Figure 2 Two sets of symmetrically arranged knobs 18 are threaded on both sides of the cast aluminum housing 11. A rubber pad 19 is rotatably installed on one end of the knob 18 inside the cast aluminum housing 11, and a second absorbing sheet 20 is fixedly installed on the other side of the rubber pad 19. A first absorbing sheet 15 that works in conjunction with the main control unit 35 is fixedly installed on the inner surface of the door 12. In use, rotating the knob 18 moves the knob 18 forward, thereby moving the rubber pad 19 and the second absorbing sheet 20 forward as well, so that the second absorbing sheet 20 fits against both sides of the main control unit 35. When the door 12 is closed, the first absorbing sheet 15 fits against the front surface of the main control unit 35, further shielding the main control unit 35 and improving the anti-interference effect. At the same time, the second absorbing sheet 20 has a shock absorption effect, which can reduce the vibration of the main control unit 35 in the left and right directions, further improving safety. Example

[0040] refer to Figure 3 and Figure 4A telescopic heat-conducting column 24, which passes through the second spring 22, is fixedly installed on the lower surface of the perforated plate 21. A heat-conducting plate 23 is fixedly installed on the lower surface of the telescopic heat-conducting column 24. The heat-conducting plate 23 abuts against the upper surface of the telescopic heat-conducting column 24. A limiting post 25 is fixedly installed on the upper surface of the perforated plate 21. A thermal expansion airbag 26 is fixedly installed inside the limiting post 25. The lower surface of the thermal expansion airbag 26 is in contact with the upper surface of the telescopic heat-conducting column 24. When in use, the main control unit 35 generates heat during operation. The heat is transferred to the telescopic heat-conducting column 24 through the electromagnetic shielding wave-absorbing plate 14. Then, the telescopic heat-conducting column 24 guides the heat into the thermal expansion airbag 26. The thermal expansion airbag 26 expands upward due to the limiting post 25.

[0041] Further reference Figure 3 and Figure 4 A fixing plate 27 is fixedly installed in the inner cavity of the cast aluminum housing 11 and above the hollow plate 21. A fan 28 is fixedly installed inside the fixing plate 27. A switch 29 for controlling the fan 28 is fixedly installed on the lower surface of the fixing plate 27. A third spring 30 is fixedly installed between the switch 29 and the fixing plate 27 for resetting the switch 29. In use, the thermal expansion airbag 26 expands and squeezes the switch 29, causing the switch 29 to turn on the fan 28 for heat dissipation. When the main control unit 35 cools down, the thermal expansion airbag 26 contracts, and the third spring 30 resets the switch 29, turning off the fan 28. The fan 28 can be automatically controlled for heat dissipation, eliminating the need for the fan 28 to work continuously and reducing operating costs.

[0042] Furthermore, Figures 3-5 Two symmetrically arranged electric telescopic rods 31 are fixedly installed on the upper surface of the fixed plate 27. The electric telescopic rods 31 are also controlled by the switch 29. The output end of the electric telescopic rods 31 is fixedly installed with a cover plate 32 for sealing the heat dissipation window 13. When in use, while the fan 28 is working, the electric telescopic rods 31 drive the cover plate 32 to move upward, so that the cover plate 32 is raised, releasing the sealing state with the heat dissipation window 13 for rapid heat dissipation. After heat dissipation, the cover plate 32 seals the heat dissipation window 13 to prevent external dust from entering the cast aluminum housing 11 and affecting the main control unit 35, thereby improving the service life of the main control unit 35.

[0043] Further reference Figure 2 The support plate 16 has an air inlet 33 inside for air intake when the fan 28 is working, ensuring the normal operation of the equipment. The bottom of the door 12 has a through groove, and a dustproof net 34 is installed inside the through groove to prevent external dust from entering the interior of the cast aluminum housing 11 when air is intake, thereby improving the performance of the equipment.

[0044] Working principle: During operation, the main control unit 35 is fixedly installed inside the electromagnetic shielding absorbing plate 14. The cast aluminum housing 11 shields the main control unit 35. Through the use of the support plate 16, the first spring 17, the hollow plate 21, and the second spring 22, the main control unit 35 can be buffered and damped vertically. Rotating the knob 18 moves the knob 18 forward, thereby moving the rubber pad 19 and the second absorbing plate 20 forward as well, so that the second absorbing plate 20 fits against both sides of the main control unit 35. When the door 12 is closed, the first absorbing plate 15 fits against the front surface of the main control unit 35, further shielding the main control unit 35. At the same time, the second absorbing plate 20 has a shock-absorbing effect, which can further shield the main control unit 35. The main control unit 35 provides shock absorption in the left and right directions. The main control unit 35 generates heat during operation. The heat is transferred to the telescopic heat-conducting column 24 through the electromagnetic shielding wave-absorbing plate 14. Then, the telescopic heat-conducting column 24 guides the heat into the thermal expansion airbag 26. The thermal expansion airbag 26 expands upward by the limiting column 25. The expansion of the thermal expansion airbag 26 squeezes the switch 29, causing the switch 29 to turn on the fan 28 for heat dissipation. At the same time, the electric telescopic rod 31 is controlled to move the cover plate 32 upward, causing the cover plate 32 to rise and release the seal with the heat dissipation window 13. After heat dissipation, the cover plate 32 seals the heat dissipation window 13 to prevent external dust from entering the cast aluminum housing 11 and affecting the main control unit 35, thereby improving the service life of the main control unit 35.
