[0058] like Figure 2 As shown, in some embodiments of the present invention, the housing 100 includes an upper shell 150 , a lower shell 160 and a middle frame 170 .

[0059] It should be noted that the middle frame 170 is a ring-shaped structure with a central opening.

[0060] Along the first direction, the upper shell 150 and the lower shell 160 are respectively disposed on two opposite sides of the middle frame 170 .

[0061] Among them, the connection method between the upper shell 150 and the middle frame 170, and the connection method between the middle frame 170 and the lower shell 160 include any one of snap connection, bonding, threaded connection, and bolt connection, which can be specifically set according to actual conditions.

[0062] In this embodiment, the upper shell 150 and the middle frame 170 are connected by a snap-fitting manner, and the lower shell 160 and the middle frame 170 are connected by a snap-fitting manner, so as to ensure the stability of the connection between the upper shell 150 and the lower shell 160 and the middle frame 170 respectively, while improving the efficiency of installation or disassembly between the upper shell 150 and the middle frame 170, as well as the efficiency of installation or disassembly between the lower shell 160 and the middle frame 170.

[0063] Specifically, a plurality of spaced-apart first clamping portions 151 are provided on an edge of the upper shell 150 facing the middle frame 170, a plurality of spaced-apart clamping grooves 171 are provided on an inner wall of the middle frame 170, and the number of the first clamping portions 151 is equal to the number of the clamping grooves 171, and each first clamping portion 151 is correspondingly clamped in a clamping groove 171, and the first clamping portion 151 is connected to one end of the clamping groove 171 close to the upper shell 150, thereby connecting the upper shell 150 with the middle frame 170.

[0065] It should be noted that there is a gap or mutual contact between the first clamping portion 151 and the second clamping portion 165 to avoid mutual abutment between the first clamping portion 151 and the second clamping portion 165, thereby ensuring the stability of the first clamping portion 151 and the second clamping portion 165 in the clamping slot 171.

[0066] like Figure 1 and Figure 7 As shown, in some embodiments of the present invention, the plurality of mounting openings 140 include a first mounting opening 141 , a second mounting opening 142 and a third mounting opening 143 .

[0067] Specifically, the first installation opening 141 , the second installation opening 142 and the third installation opening 143 are respectively disposed on the side walls of the middle frame 170 .

[0068] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the card reader body 200 has a first connection port 211 , a second connection port 212 and a third connection port 213 .

[0069] The first connection port 211 faces the first installation port 141 , the second connection port 212 faces the second installation port 142 , and the third connection port 213 faces the third installation port 143 .

[0070] Specifically, in this embodiment, the first connection port 211 is an SD card slot, the second connection port 212 is a USB interface, and the third connection port 213 is a Type-C interface.

[0073] In addition, it should be noted that the first connection portion 120 is arranged in the middle of the lower shell 160 to improve the aesthetics of the card reader while ensuring that the card reader is threadedly connected to the external carrier and improving the space utilization during the rotation of the card reader relative to the external carrier.

[0074] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the second connecting portion 130 includes a first magnet 131 and a second magnet 132 .

[0075] The magnetic properties of the first magnet 131 and the second magnet 132 are the same or opposite.

[0076] Specifically, the first magnet 131 and the second magnet 132 are respectively disposed on two opposite sides of the first connecting portion 120 , and the first magnet 131 and the second magnet 132 are spaced apart from each other.

[0077] It should be noted that, in this embodiment, the first magnet 131 and the second magnet 132 are respectively disposed between the card reader body 200 and the lower shell 160 .

[0078] In addition, the connection method between the first magnet 131 and the second magnet 132 and the lower shell 160 respectively includes bonding or clamping to prevent the first magnet 131 and the second magnet 132 from shaking in the accommodating cavity 110, thereby ensuring the stability of the first magnet 131 and the second magnet 132 in the accommodating cavity 110.

[0079] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, a first boss 161 and a second boss 162 spaced apart from each other are provided on a side of the lower shell 160 facing away from the upper shell 150 .

[0080] A first mounting groove 163 is formed on a side of the first boss 161 facing the upper shell 150 , and a second mounting groove 164 is formed on a side of the second boss 162 facing the upper shell 150 .

[0081] In addition, the first boss 161 and the second boss 162 are respectively arranged at both ends of the lower shell 160. It can be understood that the first boss 161 and the second boss 162 are respectively arranged at both ends of the length direction of the lower shell 160, or the first boss 161 and the second boss 162 are respectively arranged at both ends of the width direction of the lower shell 160, which can be specifically set according to actual conditions.

[0082] Preferably, in the present embodiment, the first boss 161 and the second boss 162 are respectively disposed at two ends of the lower shell 160 in the length direction to increase the distance between the first boss 161 and the second boss 162 .

[0083] In this embodiment, the first magnet 131 is disposed in the first installation groove 163 , and the second magnet 132 is disposed in the second installation groove 164 .

[0084] Specifically, the first magnet 131 is connected to the inner wall of the first mounting groove 163. By setting the first magnet 131 in the first mounting groove 163, the first magnet 131 is prevented from obstructing the card reader body 200 and affecting the effective utilization space of the accommodating cavity 110, thereby improving the space utilization rate inside the shell 100 and the compactness of the overall structure of the card reader, which can not only reduce the production cost but also facilitate carrying.

[0085] Similarly, the second magnet 132 is connected to the inner wall of the second mounting groove 164. The function and beneficial effect of the second magnet 132 in the second mounting groove 164 are the same as the function and beneficial effect of the connection between the first magnet 131 and the first mounting groove 163 mentioned above, and will not be repeated here.

[0086] It can be understood that by increasing the distance between the first boss 161 and the second boss 162, the distance between the first mounting groove 163 and the second mounting groove 164 is increased, thereby increasing the distance between the first magnet 131 and the second magnet 132, thereby avoiding a small distance between the first magnet 131 and the second magnet 132, which causes the first magnet 131 and the second magnet 132 to affect each other, thereby ensuring relative stability between the first magnet 131 and the second magnet 132.

[0087] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0088] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0089] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
