DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0027] The card slot design in the existing phone is generally designed for the structure of cards such as IC cards. With the development of technology, electronic devices can be inserted into the phone to use as IC cards to make calls. However, electronic devices are relatively large and have display screens, and the existing card slot structure is not suitable for the shape of electronic devices.

[0028] See also Figure 1-7 In order to solve the above problems, the utility model provides a technical solution:

[0029] like Figure 1 As shown, the utility model provides a card slot structure, including a slot body 1, a dustproof component, a SIM card contact component and a limit component. The front side of the slot body 1 is provided with a dustproof component, the upper side of the slot body 1 is provided with a support plate 3, the SIM card contact component can be movably connected to the support plate 3, and the lower side of the slot body 1 is provided with a limit component.

[0030] The card slot structure in this embodiment is used to adapt to the electronic student card, the interior of the slot is used to accommodate the device of the electronic student card, and the movable SIM card contact assembly is used to prevent the contact spring from strongly contacting the electronic student card and squeezing the device. Since the electronic student card is larger than the IC card, the insertion port of the card slot is also larger. A dustproof assembly is provided to prevent dust, liquid and other impurities from entering the card slot. The limit assembly is used to limit and fix the electronic student card so that it can be inserted into the set position to protect its housing, display screen and internal electrical components.

[0031] Furthermore, if Figure 1 As shown, the tank body 1 includes three side walls, the bottom of which is hollow, and the tank body 1, the support plate 3 and the dustproof component are enclosed to form a receiving cavity.

[0032] In this embodiment, the accommodating cavity is used to accommodate the part of the electronic student ID card 13 inserted into the card slot, and the hollow structure at the bottom of the slot body 1 is used to leak impurities that enter the slot body 1 along with the electronic student ID card 13, so as to avoid accumulation in the slot body 1 and affecting the insertion of the electronic student ID card 13.

[0033] like Figure 3 As shown, the SIM card contact assembly includes a contact spring 8 and a movable plate 2, the contact spring 8 is fixedly connected below the movable plate 2, and the movable plate 2 is movably connected to the support plate 3 through the movable assembly.

[0034] In this embodiment, in order to prevent the transfer contact of the electronic student ID card 13 from being inserted into the slot body 1 and contacting the contact spring with great strength, thereby squeezing the transfer contact downward and affecting its stability, the movable connection 2 and the support plate 3 are limited to a certain range to ensure that the contact spring 8 can be connected to the transfer contact of the electronic student ID card 13 while avoiding the wear caused by hard contact.

[0035] Furthermore, the movable component includes an elastic component and a limiting component. The elastic component includes a first screw 201 and a spring 202. The first screw 201 sequentially penetrates the movable plate 2 and the support plate 3 downward, and a limiting gasket is provided at one end of its bottom. The spring 202 is sleeved on the outside of the first screw 201 located above the support plate; the limiting component includes a second screw 203. The second screw 203 sequentially penetrates the movable plate 2 and the support plate 3 downward, and a limiting gasket is provided at one end of its bottom.

[0036] The heights of the first screw 201 and the second screw 203 are both greater than the superimposed height of the movable plate 2 and the support plate 3 , and the height of the first screw 201 is greater than the height of the second screw 203 .

[0037] In this embodiment, the first screw 201 and the spring 202 provide elastic activity space for the contact spring 8 and the movable plate 2. The movable plate 2 is a circuit board, which is used to send the communication data received by the contact spring 8 to the main circuit board of the device where the card slot structure is located. For example, in this embodiment, the card slot structure is set in a public telephone. The second screw 203 is used to limit the range of movement of the contact spring 8 and the movable plate 2 to prevent the contact spring 8 from having poor contact with the transfer contact of the electronic student card 13, thereby affecting the use.

[0038] like Figure 2 As shown, the limit assembly is laterally symmetrically fixed on the side wall of the trough body 1, including a first limit block 9 and a second limit block 10. The first limit block 9 is fixed at the corner of the rear side of the trough body 1, and the second limit block 10 is fixed at the middle position of the side wall of the trough body 1.

[0039] In this embodiment, the first limit block 9 and the second limit block 10 play a supporting and limiting role for the electronic student ID card 13 inserted into the slot body 1. The first limit block 9 and the second limit block 10 abut against the edge of the shell of the electronic student ID card 13, reducing the contact area to avoid wear while ensuring the supporting and limiting effect.

[0040] like Figure 4-5 As shown, it also includes a guide plate 12, which is fixed on the front side of the dustproof component. The guide plate 12 is provided with a socket 1201, and upwardly protruding protective blocks are symmetrically provided on both sides of the bottom of the socket 1201.

[0041] The end face of the protection block is a slope, which includes a first abutment point 1202 and a second abutment point 1203 arranged from outside to inside. The height of the first abutment point 1202 is greater than the height of the second abutment point 1203, and the second abutment point 1203 is higher than the bottom surface of the socket 1201.

[0042] In this embodiment, the electronic student ID card 13 has a display screen, which is relatively fragile. To avoid friction or squeezing of the display screen, the display screen of the electronic student ID card 13 is lifted up by protective blocks symmetrically arranged on both sides of the bottom of the socket 1201, so that there is a gap between the display screen and the bottom surface of the socket 1201. The slope formed by the first abutment point 1202 and the second abutment point 1203 on the protective block makes the protective block more consistent with the shape of the electronic student ID card 13 shell, thereby improving the stability and strength of the support.

[0043] like Figure 1As shown, the dustproof assembly includes a frame 4, a baffle 6, a shaft 5 and a torsion spring 7. The frame 4 is fixedly arranged at the front end of the trough body 1. Limiting grooves are respectively provided at both ends of the upper side of the frame 4. The shaft 5 can be rotatably connected between the limiting grooves. The baffle 6 is fixedly connected under the shaft 5. The torsion spring 7 is sleeved on the side end of the shaft 5.

[0044] In this embodiment, when the electronic student ID card 13 is inserted into the slot body 1, one end of the device pushes the baffle 6 and the shaft 5 to rotate to a horizontal state. After the electronic student ID card 13 is taken out, the torsion spring 7 keeps the baffle 6 in a vertical state close to the frame 4 to prevent dust, liquid and other impurities from entering the slot body 1.
