DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a multi-chip IC card for easy chip replacement includes a front card board 2, a rear card board 1 and an IC chip 4, the front card board 2 and the rear card board 1 are fixed by adhesive bonding, a coil slot 101 with a coil 5 inside and a plurality of chip slots 102 are provided in the rear card board 1, the IC chip 4 is located in the chip slot 102, the coil slot 101 is connected with the chip slot 102, the coil 5 is connected with the IC chip 4, a card insertion board 3 is hingedly connected to the side of the chip slot 102 away from the coil slot 101, a plurality of rectangular holes 204 connected with the chip slot 102 are provided on the side of the front card board 2, the rectangular holes 204 correspond to the positions of the chip slot 102 front and back, and the card insertion board 3 can rotate in the rectangular hole 204, a baffle slot 201 is provided on the inner side of the rectangular hole 204, and a baffle 6 capable of closing the rectangular hole 204 is connected to the baffle slot 201 by sliding left and right;

[0021] Two sets of limiting components for limiting the baffle plate 6 are arranged on the upper and lower sides of the rectangular hole 204 .

[0022] When in use, the IC chip 4 is inserted into the card insertion board 3, and the card insertion board 3 is rotated so that the IC chip 4 is located in the chip slot 102. At this time, the IC chip 4 is in contact with the coil 5, and then the baffle 6 is pushed to slide to the left along the rectangular hole 204 until the baffle 6 completely closes the rectangular hole 204. At this time, the limit component automatically limits the baffle 6 to prevent the baffle 6 from moving when not in use, thereby ensuring the reliability of the IC card when in use. When the IC chip 4 needs to be replaced, the staff pushes the baffle 6 to the right along the rectangular hole 204. At this time, the limit component automatically releases the limit. When the rectangular hole 204 is fully opened, the staff rotates the card insertion board 3 to disengage the IC chip 4 from the chip slot 102, and then pulls out the old IC chip 4, and inserts the new IC chip 4 into the card insertion board 3, and rotates the card insertion board 3 to the chip slot 102, and finally closes the rectangular hole 204 through the baffle 6, thereby improving the convenience of the staff in replacing the IC chip 4.

[0023] In this embodiment, the upper and lower sides of the rectangular hole 204 are provided with two limit slots 202 located on the front card plate 2. The limit assembly includes a limit block 7 slidably connected to the limit slot 202 and a spring 8 arranged in the limit slot 202. The upper and lower ends of the spring 8 are respectively connected to the limit block 7 and the limit slot 202. The end of the limit block 7 extending out of the limit slot 202 is integrally formed with a triangular protrusion. The front and rear ends of the upper and lower sides of the baffle 6 are provided with triangular grooves that can enable the limit block 7 to be inserted. When in use, the baffle 6 moves to the left to push the limit block 7 up. When the baffle 6 completely closes the rectangular hole 204, the triangular groove is located below the limit block 7. Under the action of the elastic force of the spring 8, the limit block 7 moves down and enables the triangular protrusion to be inserted in the triangular groove to limit the baffle 6, preventing the baffle 6 from moving when not in use, thereby ensuring the reliability of the IC card when in use. When the IC chip 4 needs to be replaced, the staff can directly push the baffle 6 to the right.

[0024] In this embodiment, a push block 9 is glued to the side of the baffle 6 away from the chip slot 102, and a push block hole 203 for the push block 9 to be inserted is opened on the front card plate 2. When in use, the staff can push the push block 9 to drive the baffle 6 to slide left and right in the baffle slot 201. When the push block 9 slides to the right and is located in the push block hole 203, the baffle 6 completely opens the rectangular hole 204, thereby facilitating the staff to replace the IC chip 4.

[0025] In this embodiment, a wavy protrusion is integrally formed on the side of the push block 9 away from the baffle 6. When in use, the wavy protrusion can increase the contact area between the staff and the push block 9, thereby increasing the friction between the staff and the push block 9 when pushing the push block 9, thereby improving the convenience of the staff when pushing the push block 9.

[0026] In this embodiment, the upper side surfaces of the front card plate 2 and the rear card plate 1 are integrally formed with hanging rings 10 of the same size and shape. When in use, the user can connect connecting components such as a sling through the hanging ring 10, making it easier for the user to carry the IC card.

[0027] In this embodiment, rubber pads 11 that fit the rectangular hole 204 are glued to the front and rear sides of the baffle 6. When in use, the rubber pads 11 can prevent water from flowing into the chip slot 102 along the gap between the baffle 6 and the rectangular hole 204, thereby increasing the service life of the IC card.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
