Description

Technical Field

[0001] This utility model relates to the field of card readers, and more particularly to a card reader for Internet of Things (IoT) systems. Background Technology

[0002] IoT access control refers to access control systems implemented through IoT technology. These systems typically consist of access controllers, card readers, and door locks, used to control the entry and exit of personnel and vehicles into restricted areas. The card reader, as the identification switch device, is a crucial component of the access control system. For example, as shown in the Chinese Patent Network's disclosure of an IoT access control system card reader (publication number CN213123122U), this type of card reader achieves waterproof functionality through the combination of a housing, through-slot, cover plate, threaded hole, sealing groove, sealing gasket, through hole, and bolts. This effectively prevents rainwater intrusion from damaging the IoT access control system card reader, improving the user experience.

[0003] However, the card readers mentioned in the above-disclosed patents and those currently used in the market still have some shortcomings: While existing methods of sealing and waterproofing card readers using encapsulated shell components offer good waterproofing, the single waterproofing function is insufficient to adapt to the complex and ever-changing usage environments, given that card readers are often located in public places and are subject to numerous external factors, resulting in poor self-protection performance. Therefore, those skilled in the art have provided a card reader for Internet of Things (IoT) systems to address the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a card reader for an Internet of Things (IoT) system, which solves the problem mentioned in the background art of poor self-protection performance of existing IoT card readers against external environments.

[0008] As a further technical solution of this utility model: the buffer assembly includes a first buffer seat embedded in the heat sink and a second buffer seat installed on the rear shell, and a buffer spring is provided between the first buffer seat and the second buffer seat.

[0009] As a further technical solution of this utility model: a sealing gasket is provided between the front shell and the rear shell, and the sealing gasket is pressed tightly between the front shell and the rear shell by positioning bolts installed on their frame.

[0010] As a further technical solution of this utility model: the back plate of the heat sink is provided with heat dissipation fins, and the heat dissipation fins are in a cross-shaped structure.

[0011] As a further technical solution of this utility model: the card reader module includes a circuit board, and the substrate of the circuit board is provided with a keyboard, a camera probe and a card reader from bottom to top.

[0012] This utility model provides a card reader for an Internet of Things (IoT) system, which has the following advantages compared with the prior art:

[0013] This card reader design uses a combination of a front shell and a rear shell as a sealed housing component, and utilizes an explosion-proof film to seal and encapsulate the card reader module, forming an integrated, tightly sealed card reader structure with excellent waterproof characteristics. Furthermore, due to the elastic tensile properties of the explosion-proof film, it maintains an elastic connection with the card reader module. With the buffer assembly providing elastic support to the card reader module through a heat sink, the card reader module is internally mounted with elastic buffering characteristics to mitigate impacts from the external environment. It possesses excellent integrated mounting characteristics while also providing waterproof and impact-resistant protection, making it more adaptable to external environments.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 This utility model provides a technical solution for a card reader for an Internet of Things (IoT) system: A card reader for an IoT system includes a front shell 1 and a rear shell 2. A sealing gasket 8 is provided between the front shell 1 and the rear shell 2. The sealing gasket 8 is pressed tightly between the front shell 1 and the rear shell 2 by positioning bolts 3 installed on their frames. By setting the sealing gasket 8 between the front shell 1 and the rear shell 2, the elastic force of the sealing gasket 8 can be used to compress and deform it, so that the front shell 1 and the rear shell 2 form a sealed housing structure. Then, by tightening the threads of the positioning bolts 3, the front shell 1 and the rear shell 2 are pressed tightly against the sealing gasket 8 to achieve a sealed encapsulation state.

[0023] As a further embodiment, the front shell 1 is provided with an explosion-proof membrane 4 inside. The explosion-proof membrane 4 is made of either natural rubber or silicone material, and it is sealed to the card reader module 5. By utilizing the elastic tension characteristics of the explosion-proof membrane 4, the explosion-proof membrane 4 and the card reader module 5 can be kept in a sealed connection, further improving the sealing characteristics of the card reader to achieve its waterproof function. At the same time, the control components of the card reader module 5 can be exposed without affecting normal operation and card reading.

[0024] Example 2

[0025] Please see Figure 2-5 This embodiment further explains Example 1. A card reader module 5 is provided through the explosion-proof membrane 4, so that the explosion-proof membrane 4 elastically stretches the card reader module 5. By utilizing the elastic tension of the explosion-proof membrane 4 on the card reader module 5, it not only has sealing and waterproof characteristics, but also elastic tension and buffer protection characteristics, so as to reduce the damage caused by external impact to the card reader module 5.

[0026] In addition, the card reader module 5 includes a circuit board 51. The base plate of the circuit board 51 is provided with a keypad 52, a camera probe 53, and a card reader 54 from bottom to top. The elastic tension of the explosion-proof film 4 makes it easier to expose the external control components of the keypad 52, camera probe 53, and card reader 54, forming a method in which the control components are exposed and the processing board components are sealed and built-in.

[0027] Furthermore, the rear shell 2 has at least one set of buffer components 7 inside, with four sets of buffer components 7 respectively located on the edges of the rear shell 2 and the heat sink 6. Each buffer component 7 includes a first buffer seat 71 embedded in the heat sink 6 and a second buffer seat 72 mounted on the rear shell 2. A buffer spring 73 is provided between the first buffer seat 71 and the second buffer seat 72. During normal use of the card reader module 5, the buffer components 7 support the card reader module 5 through the heat sink 6 to keep the card reader module 5 in a stable state for operation. When the card reader module 5 is subjected to external impacts, if the impact is greater than the elastic compressive force of the buffer components 7, the elastic compression of the buffer components 7 and the elastic deformation of the explosion-proof film 4 under pressure will cause the card reader module 5 to spring displacement, thereby reducing the impact from the outside.

[0028] Example 3

[0029] Please see Figure 2-4 This embodiment further illustrates other embodiments: the heat sink 6 is disposed on the back plate of the card reader module 5 and connected to the buffer assembly 7. The back plate of the heat sink 6 is provided with heat dissipation fins 61, and the heat dissipation fins 61 have a cross-shaped structure. By attaching the heat sink 6 to the back plate of the card reader module 5, it can not only provide back support to improve the uniformity of force on the card reader module 5, but also provide heat conduction and heat dissipation. Together with the heat dissipation fins 61, it conducts heat dissipation for the daily mechanical heat of the card reader module 5, thereby improving the stability of the card reader in daily use.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
