Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of protection mechanism, can prevent foreign matter to invade card reading device inside, and promote the stability when card is inserted and pulled out. BACKGROUND

[0002] Credit card, financial card, Easy Card or health card etc. used in daily life can access data in chip by inserting card into card reading device such as cash machine, POS machine or chip card reader. However, dust, liquid and other foreign matter may enter card reading device inside from card slot of card reading device, causing parts damage, resulting in poor chip contact, thereby affecting service life of card reading device.

[0003] For example, Chinese Utility Model Patent No. 217823456 discloses an IC card seat with protection function, which includes a card seat body with a card insertion port and an internal mounting space. A semi-closed slot has an open end and a closed end. The open end is installed on the card seat body. The semi-closed slot has a card insertion slot inside. The opening of the card insertion slot is arranged at the open end and is in communication with the card insertion port. The closed end extends into the internal mounting space, so that the card insertion slot and the internal mounting space are separated from each other, thereby preventing external debris from entering the internal mounting space through the card insertion slot and causing internal parts damage. However, in this structure design, since no blocking structure is provided between the card insertion slot and the card insertion port, external debris may enter through the card insertion port and accumulate inside the card insertion slot, resulting in a situation where the chip card reading fails.

[0004] A card reader with a protection mechanism is disclosed in Taiwan Utility Model Patent Certificate No. M650257. The card reader includes an upper housing having a card insertion channel, a lower housing coupled to the upper housing, and a protection mechanism disposed between the upper housing and the lower housing. The protection mechanism includes a protection shell and a dustproof sheet. The protection shell has a slot formed through the front and rear surfaces thereof. The slot is in communication with the card insertion channel. The protection shell has an insertion end adjacent to the card insertion channel and an exit end opposite to the insertion end. The dustproof sheet is disposed at the exit end. The dustproof sheet includes an upper dustproof sheet and a lower dustproof sheet. When a card is inserted into the card reader through the card insertion channel, the upper dustproof sheet and the lower dustproof sheet are deformed towards the interior of the card reader. After the card is withdrawn, the upper dustproof sheet and the lower dustproof sheet are automatically restored to their original positions. The bottom end of the upper dustproof sheet contacts the top end of the lower dustproof sheet and covers the exit end, thereby preventing foreign matter from entering the interior of the card reader. However, in this structure, the dustproof sheet is adhered to the exit end by a back adhesive. After a long period of use, the dustproof sheet may be deformed or detached due to the decrease in the adhesion of the back adhesive. In addition, the dustproof sheet is made of a material that can be deformed and restored automatically. When the card passes through the dustproof sheet, a large frictional resistance is generated, thereby affecting the smoothness of the card insertion and withdrawal. In view of the above shortcomings, it is necessary to provide a protection mechanism that can prevent foreign matter from entering the interior of a card reader and improve the stability of the card insertion and withdrawal.

The protection mechanism 100 comprises a fixing structure 1, a first dustproof sheet 16, a second dustproof sheet 17, a first guide plate 21 and a second guide plate 22. A through hole 18 is arranged in the center of the fixing structure 1, and the through hole 18 is arranged in a long slot shape and aligned with the insertion opening 202. The first dustproof sheet 16 and the second dustproof sheet 17 are flexible elements, and are respectively extended from the inner surface of the fixing structure 1 to the through hole 18. The two opposite inner surfaces of the through hole 18 are respectively provided with the first dustproof sheet 16 and the second dustproof sheet 17 extending towards each other, and the ends of the first dustproof sheet 16 and the second dustproof sheet 17 are opposite to each other and maintain a distance. The first guide plate 21 and the second guide plate 22 are rigid elements, the first guide plate 21 is arranged at the end of the first dustproof sheet 16, and the second guide plate 22 is arranged at the end of the second dustproof sheet 17. The first dustproof sheet 16 and the second dustproof sheet 17 are symmetrically arranged along the center line of the through hole 18, so that the first guide plate 21 arranged on the first dustproof sheet 16 and the second guide plate 22 arranged on the second dustproof sheet 17 abut each other, so as to close the through hole 18, thereby preventing foreign matters from invading the interior of the card reading device 200 through the insertion opening 202.

[0026] Please refer to Figures 1 to 3The fixing structure 1 is set as a rectangular body with an inner cavity, and comprises a top wall 12 and a bottom wall 13 respectively located on the upper and lower sides of the fixing structure 1, and two side walls 14 respectively located on the left and right sides of the fixing structure 1. The first dustproof sheet 16 is shaped by extending from the inner surface of the top wall 12 to the through hole 18 and covers part of the through hole 18, and the second dustproof sheet 17 is shaped by extending from the inner surface of the bottom wall 13 to the through hole 18 and covers part of the through hole 18. A cutting groove 19 is arranged on the left and right sides of the first dustproof sheet 16 and the left and right sides of the second dustproof sheet 17, respectively, and the cutting groove 19 communicates with the through hole 18, so that the first dustproof sheet 16 and the second dustproof sheet 17 are separated from the two side walls 14, and the cutting groove 19 is arranged to improve the deformation force of the first dustproof sheet 16 and the second dustproof sheet 17.

In this preferred embodiment, the first guide plate 21 and the second guide plate 22 are made of metal material. Compared with the prior art, since the friction coefficient of metal is smaller than that of flexible soft material, the frictional resistance when the card 300 is inserted and pulled out is reduced. The first guide portion 211 and the second guide portion 221 are provided in a circular arc structure, so that the insertion and pulling out of the card 300 is smoother. However, the specific implementation is not limited thereto.
