[0050] like Figure 6 , Figure 7As shown, the present application provides a fixing structure that is convenient for installing and using the wireless communication module 7. The image forming device of the present embodiment further comprises a supporting plate 8, which is made of non-metallic material and is arranged on the side cover 11. The wireless communication module 7 is arranged on the supporting plate 8, so that the supporting plate 8 can support the wireless communication module 7. In the third direction, the supporting plate 8 is closer to the upper side of the frame 1, and the supporting plate 8 is provided with a first supporting portion 81, a second supporting portion 82 and a joint portion 83. In the second direction, the first supporting portion 81 and the second supporting portion 82 are arranged opposite to each other, and the first supporting portion 81 is closer to the rear side of the frame 1. The first supporting portion 81 A bending structure design is adopted, and a connecting hole 811 and a positioning hole 812 are provided on the first support portion 81. The connecting hole 811 and the positioning hole 812 are both through-hole structures with different apertures. A positioning column 112 and a fixing hole 113 are provided on the side cover 11 (on the right side of the frame 1). The positioning column 112 adopts a protruding columnar structure and is arranged corresponding to the positioning hole 812. The fixing hole 113 is preferably a threaded hole and is arranged corresponding to the connecting hole 811. The positioning hole 812 is connected to the positioning column 112 in correspondence to align the positioning connecting hole 811 with the fixing hole 113, and then fixed by a fixing member (such as a screw) to complete the fixation of one end of the support plate 8. The second support portion 82 is a portion extending forward along the second direction. A mounting portion 111 is provided on the side cover 11. The mounting portion 111 adopts a deformable hook structure with an opening facing upward. When the second support portion 82 is installed downward along the third direction, it can be engaged with the mounting portion 111 to complete the fixation of the other end of the support plate 8. The projections of the second support portion 82 and the first support portion 81 in the third direction do not overlap with the projection of the wireless communication module 7, that is, the wireless communication module 7 and the second support portion 82 and the first support portion 81 do not interfere with or overlap each other, and do not affect the installation of the wireless communication module 7 on the main body of the support plate 8. The second support portion 82 has a wire clamping portion 821 protruding upward.

[0051] like Figure 6As shown, the joint part 83 can be integrally formed and arranged on the support plate 8. In this embodiment, the joint part 83 adopts a positioning columnar structure protruding upward along the third direction. There are two of them, which are respectively arranged in the first direction. The wireless communication module 7 is provided with a connecting part 71. The number of the connecting parts 71 corresponds to the joint part 83. In this embodiment, the number of the connecting parts 71 is set to two, that is, the connecting part 71 includes a first connecting part and a second connecting part, and the joint part 83 includes a first joint part and a second joint part. The position of the connecting part 71 also corresponds to the position of the joint part 83 to facilitate installation. The connecting part 71 is specifically a through-hole structure, and the joint part 83 and the connecting part 71 are matched with the shaft hole. In this embodiment, the wireless communication module 7 can be fixedly connected to the support plate 8. In other embodiments, the wireless communication module 7 and the support plate 8 can also be detachably connected, as long as the connection strength between the two can be guaranteed. When the wireless communication module 7 of this embodiment is installed on the support plate 8, the joint part 83 cooperates with the shaft hole of the connecting part 71 so that the wireless communication module 7 is limited to the support plate 8, and then the joint part 83 is deformed by hot melting. Figure 10-11 As shown, for example, after heating, the end of the joint portion 83 is pressed into a flat shape (umbrella shape), and the wireless communication module 7 can be fixed on the support plate 8. Other non-detachable methods can also be used to fix the wireless communication module 7 on the support plate 8, such as using hot melt bonding to fix the wireless communication module 7. Therefore, the joint portion 83 can be deformably arranged on the support plate 8, and the deformation method is not limited to hot melt, and other methods such as folding limit, expansion clamping, etc. can also be realized.

[0052] After the wireless communication module 7 is fixed on the support plate 8, the support plate 8 is installed on the side cover 11, and the support plate 8 is detachably connected to the side cover 11 by installing the first support portion 81 and the second support portion 82. Therefore, when the wireless communication module 7 may need to be maintained and repaired, the operator directly installs the support plate 8 without easily contacting the circuit board of the wireless communication module 7, and it is not easy to cause the circuit board to be damaged by static electricity.

[0053] The wireless communication module is at least one of a WiFi module, a Bluetooth module and an NFC module.

[0054] Further, such as Figure 8 , Fig. 9As shown, the image forming device also includes a protective cover 9, which is detachably connected to the frame sheet metal 6. The protective cover 9 is a rectangular cover structure. In the second direction, the protective cover 9 is provided with a first matching portion 91 and a second matching portion 92 that are relatively arranged. The first matching portion 91 and the second matching portion 92 both adopt a recessed structure. The bottoms of the first matching portion 91 and the second matching portion 92 have a through-hole structure. The side cover 11 is provided with threaded holes on both sides in the second direction, which can correspond to the first matching portion 91 and the second matching portion 92 respectively. When the protective cover 9 is installed on the side cover 11, the first matching portion 91 and the second matching portion 92 are aligned with the threaded holes and then fixed by screws to achieve a detachable connection; the protective cover 9 is also provided with a third matching portion 93 and a fourth matching portion 94. The third matching portion 93 is closer to the front side of the protective cover 9. The third matching portion 93 also has a through-hole structure and is connected to the frame by screws. 1, the fourth matching portion 94 is located in the middle position of the protective cover 9, and adopts a groove structure with a through hole at the bottom, which can correspond to the threaded hole of the frame sheet metal and be connected by screws. Specifically, the protective cover 9 can cover the wireless communication module 7 and the support plate 8. When the support plate 8 is installed, the protective cover 9 is detachably connected to the side cover 11, so that the protective cover 9 can protect the wireless communication module 7. When maintenance and repair are required, the protective cover 9 needs to be removed first, and the protective cover 9 can ensure that the wireless communication module 7 is not exposed to the outside of the frame 1. Even if the operator opens the top cover 2 to replace the imaging unit 3 such as the powder box, the protective cover 9 still covers the wireless communication module 7, so that the operator will not accidentally touch the wireless communication module 7. To a certain extent, it can also block dust and other debris that reduce the service life of the wireless communication module 7, which is beneficial to protecting the wireless communication module 7.

[0055] In some embodiments, Fig.12 , Fig.13 As shown, the joint part 83 has a limiting part 831, and the limiting part has a certain deformation ability. The wireless communication module 7 is snap-fitted with the support plate 8. Specifically, the joint part 83 is constructed as a snap-fit ​​structure, and the limiting part adopts an inclined smooth protrusion structure. The volume gradually decreases upward in the third direction, so that the joint part 83 forms a structure similar to an "umbrella shape". The connecting part 71 gradually slides downward along the limiting part 831 until the connecting part 71 is out of contact with the limiting part, so that the connecting part 71 can be limited by the bottom of the limiting part 831 to complete the fixed connection between the wireless communication module 7 and the support plate 8. The connection strength is high and the operation is simple.

[0056] In some embodiments, Figure 14-15As shown, the joint part 83 is constructed as a structure of an interference positioning column. When the connecting part 71 is clamped downward on the joint part 83, the joint part 83 can form an interference fit with the connecting part 71, so that the two can be relatively clamped, and the wireless communication module 7 can be fixed on the support part. For example, the joint part 83 is designed to be a structure with ribs, and the ribs are annularly surrounded along the axial direction of the joint part 83. The outer contour of the ribs along the third direction has a size difference to achieve a better interference fit. During the fitting process, the outer contour of the joint part 83 can be slightly deformed.

[0057] In some embodiments, the joint portion 83 includes a first joint portion and a second joint portion. The first joint portion can be set as a through hole structure, which needs to be aligned with the connecting portion 71 when used, that is, the two hole structures are aligned. The first joint portion can be constructed as a through hole or a blind hole structure, and the second joint portion is constructed as a snap-fit ​​structure integrally connected to the support plate 8. The portion of the second joint portion connected to the main body of the support plate 8 can undergo flexible deformation (connecting band shape). When the wireless communication module 7 is installed on the support plate 8, the first joint portion and the connecting portion 71 are positioned through the axial hole, and then the second joint portion is used to pass through the connecting portion 71 and The second engaging portion is interlocked with the first engaging portion, and a portion of the first engaging portion can be pressed and fixed to the support plate 8, that is, the second engaging portion passes through the connecting portion 71 and is connected to the first engaging portion, so as to complete the detachable connection of the wireless communication module 7 to the support plate 8. The connecting portion 71 includes a first connecting portion and a second connecting portion, that is, the number of holes in the connecting portion 71 is set to two, and then the connection strength is increased by fixing with two second engaging portions to avoid tilting and deviation. In this embodiment, the support plate 8 can be integrally formed and arranged on the side cover 11, so that the wireless communication module 7 is a detachable part, which is convenient for subsequent maintenance and repair.

[0058] In some embodiments, the image forming device further comprises a connector, which is constructed as a screw structure, preferably a resin screw, the joint portion 83 adopts a protruding columnar structure, and a threaded hole capable of threading with the connector is provided inside the joint portion 83, and the connecting portion 71 adopts a through-hole structure. When the wireless communication module 7 is mounted on the support plate 8, the first joint portion and the connecting portion 71 are positioned through the shaft hole, and then the wireless communication module 7 can be detachably mounted on the support plate 8 by using the connector to pass through the connecting portion 71 and the connector and the joint portion to thread and fasten each other. Therefore, the fixing structure for fixing the wireless communication module 7 on the support plate 8 is made of non-metallic material, which can effectively prevent the signal of the wireless communication module 7 from being interfered.

[0059] In some embodiments, the engaging portion 83 includes a first engaging portion and a second engaging portion. The first engaging portion can be constructed as a positioning column structure, which is integrally formed with the support plate 8. The first engaging portion cooperates with the connecting portion 71 through a hole axis to limit the position of the wireless communication module 7. The second engaging portion can be constructed as a card slot structure, and the wireless communication module 7 is provided with a fixing portion, which can be constructed as a protruding structure that cooperates with the card slot. After being positioned by the first engaging portion and the connecting portion 71, the second engaging portion is engaged with the fixing portion to realize the detachable connection of the wireless communication module 7 to the support plate 8. Of course, The structures of the second joining portion and the fixing portion can be used interchangeably. It can be understood that the connecting portion 71 includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the first joining portion through a hole-axis fit, and the second connecting portion is the fixing portion, which is snap-fitted with the second joining portion and the fixing portion to fix the support plate 8. In this embodiment, the support plate 8 can be integrally formed and arranged on the side cover 11, so that the wireless communication module 7 is a detachable part to facilitate subsequent maintenance and repair, and the joining portion 83 and the fixing portion are both made of non-metallic materials such as plastic, resin, etc., which can effectively prevent the signal of the wireless communication module 7 from being interfered with.
