[0059] As described in the background, in the related art, when the toner cartridge is inserted into the body of the image forming apparatus, the first conductive contact on the body side of the image forming apparatus and the second conductive contact on the toner cartridge are not stably electrically connected, which affects the normal operation of the image forming apparatus. The inventors have found that the reason for this problem is that when the toner cartridge is inserted into the body, the driving head in the image forming apparatus is in driving connection with the toner cartridge and provides a rotating force to the toner cartridge, so that the carbon powder transmission device in the toner cartridge rotates, so that the toner cartridge can provide toner to the image forming apparatus.

[0060] However, in the above image forming apparatus, the rotating force easily causes relative movement between the first conductive contact and the second conductive contact, resulting in unstable electrical connection between the two, thereby affecting the normal operation of the image forming apparatus.

[0061] To solve the above technical problems, the embodiments of the present application provide a positioning adapter, an adapter, a cartridge, a cartridge set and an image forming apparatus. The positioning adapter is mounted on the cartridge. The positioning adapter is in cooperation with the first positioning matching part provided on the body of the image forming apparatus through the first positioning part, so as to position the first engaging part and make the first engaging part in driving connection with the first driving head. Thus, the cartridge is detachably mounted on the body. The first conductive contact on the body side of the image forming apparatus and the second conductive contact on the cartridge are in contact and form a plurality of contact points.

[0062] Further, the outermost profile of the first positioning part is configured to be greater than or equal to the maximum distance of the connection line between any two contact points of the plurality of contact points between the first conductive contact and the second conductive contact on the transverse section of the body of the image forming apparatus. In this way, the influence of the driving force from the first driving head on the contact between the first conductive contact and the second conductive contact can be reduced, so as to avoid the relative movement between the first conductive contact and the second conductive contact, to ensure the stable contact between the first conductive contact and the second conductive contact, and to ensure the normal operation of the image forming apparatus.

[0063] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0064] Embodiment one

[0065] For the convenience of describing the embodiments of the present application, first, the coordinate system in the drawing is described, wherein the X-axis is defined as the first direction, which can be the length direction of the image forming apparatus body 10, and can also be regarded as the left and right direction; the Y-axis direction is defined as the second direction, which can be the width direction of the image forming apparatus body 10, and can also be regarded as the front and back direction; and the Z-axis direction is defined as the third direction, which can be the height direction of the image forming apparatus body 10, and can also be regarded as the up and down direction.

[0066] As shown in Figure 1 and Figure 2 , the image forming apparatus 100 provided by the embodiments of the present application includes a body 10 and a cartridge group and an imaging assembly 30 installed in the body 10, wherein the body 10 includes an installation cavity, and the front end of the installation cavity has an opening in the second direction, so as to facilitate the installation of the cartridge group and the imaging assembly 30 into the installation cavity.

[0067] Specifically, the image forming apparatus body 10 is in a rectangular shape, which is provided with an installation cavity, for example, the installation cavity is in a rectangular shape, or is in an irregular shape, the front end of the installation cavity has an opening, and a front cover 40 that can be opened and closed is arranged at the edge of the opening, and the front cover 40 can seal the opening when in a closed state, so as to close the installation cavity. The cartridge group in the embodiments of the present application can include at least one cartridge 20, and the cartridge group can be inserted into the installation cavity, that is, the cartridge group can be detachably installed into the body 10, and further, the image forming apparatus 100 includes at least one cartridge 20, which can be a toner cartridge, and the toner cartridge contains toner for printing.

[0068] In the third direction, the cartridge group can be arranged above the imaging assembly 30, and the cartridge group includes four toner cartridges arranged in sequence in the first direction, and each cartridge can contain toner of different colors, which is not limited in the embodiments. When the toner cartridge is installed into the installation cavity and positioned, the toner cartridge can provide toner to the imaging assembly 30, and the toner cartridge establishes electrical connection communication with the image forming apparatus 100.

[0069] As shown in Figure 3 , Figure 6 and Figure 7 , the image forming apparatus 100 provided by the embodiments of the present application further includes a first driving head 60, a stylus assembly and a first positioning matching part 11 arranged in the installation cavity, wherein the first positioning matching part 11 and the first driving head 60 are opposite to the first end of the toner cartridge in the second direction; the stylus assembly includes a plurality of styluses, a part of the styluses is electrically connected with the body 10, and another part of the styluses is exposed in the installation cavity and is used for electrical connection with the toner cartridge, so that the image forming apparatus 100 establishes communication with the toner cartridge through the stylus assembly, and the part of the styluses exposed in the installation cavity forms a first conductive contact 50.

[0070] As shown in Figure 4As shown, the toner cartridge includes a housing 21 and a storage device 22 and a first engaging portion 24 disposed on the housing 21. The housing 21 is in a long strip shape as a whole, and includes a first end and a second end oppositely disposed along a second direction (a toner cartridge insertion direction), wherein the first end is opposite to the first driving head 60, the first engaging portion 24 is disposed on an end face of the first end of the housing 21, the first engaging portion 24 is opposite to the first driving head 60, and the first engaging portion 24 cooperates with the first driving head 60. When the toner cartridge is inserted into the installation cavity and installed in place, the first driving head 60 can be in driving connection with the first engaging portion 24 to input driving force to the toner cartridge, and to rotate the toner conveying device in the toner cartridge to provide toner to the image forming assembly 30. In the present application, installation in place is explained as that the toner cartridge is installed into the image forming device 100 and can perform image forming operation, such as normal printing and normal toner supply.

[0071] The storage device 22 is used to store toner information of the toner cartridge, and can be a chip of the toner cartridge. The storage device 22 includes a substrate 221 and a plurality of communication terminals disposed on the substrate 221. The communication terminals are located on a side of the substrate 221 in contact with the first conductive contacts 50, so that after the toner cartridge is inserted into the installation cavity and installed in place, the communication terminals are in contact with and electrically connected to the corresponding first conductive contacts 50.

[0072] For example, the storage device 22 is disposed on the top of the housing 21 along the third direction, and correspondingly, the first conductive contacts 50 formed by the stylus assembly are located below the top wall of the installation cavity, that is, the first conductive contacts 50 are opposite to the chip when the toner cartridge is inserted into the installation cavity.

[0073] Each of the above communication terminals forms a second conductive contact 222, and the plurality of second conductive contacts 222 include a VCC contact, an SDA contact, a GND contact and an SCL contact. The VCC contact is used to contact and conduct electricity with an external power supply unit to obtain a voltage required for the chip to work. The SDA contact is a data communication contact. The GND contact is a ground contact. The SCL contact is a clock signal contact. The four second conductive contacts are respectively electrically connected to the corresponding first conductive contacts 50 to realize electrical conduction between the chip and the body 10.

[0074] On the basis of the above embodiment, the present application further provides a positioning adapter, which can be installed on the housing 21 of the toner cartridge and is used to position the toner cartridge when the toner cartridge is inserted into the installation cavity.

[0075] In the present application, the positioning adapter includes a first positioning portion 23, which can be detachably installed on the housing 21 of the toner cartridge. Further, the positioning adapter further includes a fixing portion configured to detachably dispose the first positioning portion 23 on the housing 21 of the toner cartridge.

[0076] Exemplarily, the first positioning portion 23 is located on the end face of the first end of the shell 21, that is, the first positioning portion 23 and the first engaging portion 24 are both located on the end face of the first end of the shell 21, the first positioning portion 23 is oppositely arranged with the first positioning matching portion 11, and the first positioning portion 23 is adapted to the first positioning matching portion 11. For example, the first positioning portion 23 can be a positioning protrusion, the first positioning matching portion 11 can be a positioning groove matched with the positioning protrusion, and the like, which are not limited in the embodiments of the present application.

[0077] As shown in Figure 5 , when the toner cartridge with the above positioning adapter is inserted into the mounting cavity of the body 10, the first positioning portion 23 is matched with the first positioning matching portion 11 to position the first engaging portion 24, so that the first engaging portion 24 is in transmission connection with the first driving head 60, that is, the driving force of the first driving head 60 can be transmitted to the carbon powder transmission device in the toner cartridge through the first engaging portion 24.

[0078] Further, when the toner cartridge is inserted into the mounting cavity of the body 10 and installed in place, the second conductive contact 222 of the toner cartridge is in contact with the first conductive contact 50, and a plurality of contact points are formed. The maximum distance (distance H in Figure 5 ) between any two contact points of the plurality of contact points in which the first conductive contact 50 is in contact with the second conductive contact 222 in the transverse cross section of the body 10 is less than or equal to the maximum width (width D in Figure 5 ) of the outermost profile of the first positioning portion 23 in the transverse cross section of the body 10, and the transverse cross section is the X direction shown in the figure.

[0079] Compared with the related art, the maximum width D of the outermost profile of the first positioning portion 23 in the transverse cross section of the body 10 is configured to be greater than or equal to the maximum distance H between any two contact points of the plurality of contact points in which the first conductive contact 50 is in contact with the second conductive contact 222 in the transverse cross section of the body 10.

[0080] In this way, the influence of the driving force from the first driving head 60 on the contact between the first conductive contact 50 and the second conductive contact 222 can be reduced, the relative movement between the first conductive contact 50 and the second conductive contact 222 can be avoided, the contact between the first conductive contact 50 and the second conductive contact 222 is more stable, and the normal work of the image forming apparatus 100 is ensured.

[0081] On the basis of the above-mentioned embodiments, as shown in Figure 8 , the first positioning portion 23 can be integrated on the shell 21 in the embodiments of the present application. For example, the first positioning portion 23 can be configured as a first positioning cylinder 231 in the shape of a ring, the first positioning cylinder 231 is integrally arranged on the end face of the first end of the shell 21, and the first positioning cylinder 231 is arranged around the periphery of the first engaging portion 24.

[0082] The first positioning part 23 of the embodiment of the present application is detachably mounted on the shell 21 of the powder box. As shown, the first positioning part 23 is provided with at least one first plug-in post 233, and correspondingly, the shell 21 is provided with a first plug-in hole 211 matched with the first plug-in post 233, and the first plug-in hole 211 can be located on the end face of the first end of the shell 21. Figure 9

[0083] For example, the shell 21 of the powder box includes a mounting area 210, and the first plug-in hole 211 is located in the mounting area 210 of the shell 21. When it is needed to mount the positioning adapter on the powder box, the first plug-in post 233 can be inserted into the first plug-in hole 211, and further, the first positioning part 23 has a bottom surface facing the end face of the first end, which can be attached to the end face of the first end. The embodiment is not limited in this regard.

[0084] When the positioning adapter is mounted on the powder box in the embodiment of the present application, the first positioning part 23 is annularly arranged outside the first meshing part 24, and the specific implementation is as follows:

[0085] Continuing to refer to Figure 9 In one embodiment, the first positioning part 23 is configured as a first positioning cylinder 231 in a circular ring shape. Along the insertion direction of the first positioning cylinder 231 (consistent with the Y-axis direction), the end face of one end of the first positioning cylinder 231 is provided with a mounting edge, and the mounting edge is annularly arranged on the peripheral wall of the first positioning cylinder 231 along the circumferential direction of the first positioning cylinder 231. The first positioning cylinder 231 can be mounted on the end face of the first end of the shell 21 through the mounting edge, and the first positioning cylinder 231 is sleeved on the periphery of the first meshing part 24.

[0086] For example, the mounting edge is provided with the first plug-in post 233 on the side facing the shell 21, and the shell 21 is provided with the first plug-in hole 211 matched with the first plug-in post 233. The first positioning cylinder 231 is inserted into the first plug-in hole 211 through the first plug-in post 233, so that the first positioning cylinder 231 is mounted on the shell 21, and the side face of the positioning edge can be attached to the end face of the first end of the shell 21.

[0087] It should be noted that the first positioning part 23 is configured as the first positioning cylinder 231. When the powder box with the positioning adapter is inserted into the mounting cavity of the body 10 and mounted in place, the first conductive contact 50 and the second conductive contact 222 are in contact and form a plurality of contact points. In the plurality of contact points, the maximum connecting distance (the distance H in the formula) of any two contact points in the transverse cross section of the body 10 is less than or equal to the diameter of the first positioning cylinder 231. Figure 5

[0088] ​​This configuration reduces the impact of the driving force from the first driving head 60 on the contact between the first conductive contact 50 and the second conductive contact 222, thereby preventing relative movement between the first conductive contact 50 and the second conductive contact 222 and making the contact between the first conductive contact 50 and the second conductive contact 222 more stable.

[0089] like Figure 10 As shown, in another embodiment, the first positioning part 23 includes at least three first positioning posts 232, and each first positioning post 232 is arranged around the periphery of the first engaging part 24. Correspondingly, the first positioning mating part 11 that cooperates with the first positioning part 23 includes a first positioning hole, which is provided to cooperate with the first positioning post 232 so that the first positioning post 232 can be inserted into the first positioning hole. That is, the body 10 of the image forming apparatus 100 is provided with a first positioning hole that cooperates with the first positioning post 232, and when the toner cartridge having this type of first positioning part 23 is inserted into the mounting cavity, each first positioning post 232 can be inserted into the corresponding first positioning hole, thereby realizing the positioning of the toner cartridge.

[0090] It should be noted that the first positioning part 23 is configured with at least three first positioning posts 232. When the powder box with the positioning adapter is inserted into the mounting cavity of the body 10 and installed in place, the first conductive contact 50 and the second conductive contact 222 contact each other and form multiple contact points. Among the multiple contact points, the maximum line distance between any two contact points on the transverse cross section of the body 10 is less than or equal to the maximum width of the outermost contour enclosed by each first positioning post 232 on the transverse cross section of the body 10.

[0092] When the powder box with the above-mentioned positioning adapter is inserted into the mounting cavity and installed in place, the first conductive contact 50 and the second conductive contact 222 contact each other and form multiple contact points. Among the multiple contact points, the maximum line distance between any two contact points on the transverse cross section of the body 10 is less than or equal to the diameter of the circle.

[0093] Continue reading Figure 5 and Figure 6 The powder box in this embodiment of the application is also provided with a first bracket 26. The first bracket 26 is disposed on the housing 21 of the powder box. The first bracket 26 is used to install the storage device 22 and to place the storage device 22 on the top of the housing 21.

[0094] For example, the first support 26 is L-shaped, which includes a horizontal bearing portion and a mounting portion connected thereto, wherein the mounting portion is located below the horizontal bearing portion along the third direction, the first support 26 is mounted on the end face of the first end of the housing 21 through the mounting portion, the horizontal bearing portion is arranged on the top of the housing 21, and the chip substrate 221 is mounted on the bearing surface of the horizontal bearing portion in the Y direction, and the end face of the substrate 221 is flush with the end of the bearing surface of the horizontal bearing portion.

[0095] Further, the first support 26 is further provided with a first limiting protrusion 261, which is located on the side of the mounting portion away from the horizontal bearing portion along the third direction. The first limiting protrusion 261 extends along the third direction and extends into the first positioning portion 23, and is opposite to the first driving head 60 along the second direction, which can limit the first engaging portion 24 in the second direction to prevent the first engaging portion 24 from moving in the second direction, and improve the transmission connection reliability of the first engaging portion 24 and the first driving head 60.

[0096] When the first positioning portion 23 is configured as a first positioning cylinder 231, the first positioning cylinder 231 is provided with a first notch near the position of the first limiting protrusion 261, and the first notch is matched with the first limiting protrusion 261 to enable the first limiting protrusion 261 to be embedded into the first notch. When the positioning adapter with the first positioning cylinder 231 is mounted on the powder cartridge, the first notch accommodates the first limiting protrusion 261, and the first limiting protrusion 261 is opposite to the end face of the first engaging portion 24 to axially limit the first engaging portion 24 in the second direction.

[0097] As shown in the Figures 3 to 5 The powder cartridge provided by the embodiment of the present application further includes a second positioning portion 25. Correspondingly, the body is provided with a second positioning matching portion 12 adapted to the second positioning portion 25. The second positioning portion 25 is arranged on the end face of the first end of the housing 21, and when the positioning adapter is mounted on the powder cartridge, the first positioning portion 23 and the second positioning portion 25 are both located on the end face of the first end, the first positioning portion 23 is arranged close to the second positioning portion 25, and along the third direction, the first positioning portion 23 is located above the second positioning portion 25. When the powder cartridge is mounted into the mounting cavity of the body 10, the first positioning portion 23 and the second positioning portion 25 can jointly position the powder cartridge.

[0099] For example, the first positioning part 23 includes three first positioning columns 232, and when the toner cartridge with the positioning adapter is installed into the installation cavity of the image forming apparatus body 10 and positioned, the three first positioning columns 232 surround the periphery of the first engaging part 24, and the three first positioning columns 232 are all located on the concentric circle of the rotation path of the first engaging part 24, and the rotation path is the contour formed by the circumferential rotation of the outermost contour of the first engaging part 24. In another embodiment, the three first positioning columns 232 are located on the non-concentric circle of the rotation path of the first engaging part 24, which is not limited herein.

[0100] Further, the second positioning part 25 described above includes at least one second positioning column 251, the second positioning matching part 12 includes a second positioning hole matched with the second positioning column 251, and the second positioning column 251 can be configured as a pre-positioning column, which can be pre-positioned by using the second positioning column 251 when the toner cartridge with the first positioning part 23 is inserted into the installation cavity, and further positioned by using the first positioning part 23. In this way, the positioning and installation of the toner cartridge can be facilitated.

[0101] Further, the toner cartridge is only provided with the first positioning part 23, and the second positioning part 25 is omitted, and the installation and positioning of the toner cartridge can also be achieved by only using the first positioning part 23 to further position when the toner cartridge with the first positioning part 23 is inserted into the installation cavity.

[0102] Embodiment Two

[0103] On the basis of the above-mentioned embodiment one, the application provides an adapter, which can be installed on the toner cartridge, and when the toner cartridge needs to be inserted into the installation cavity of the image forming apparatus body 10, the adapter can be used for positioning, so that the first engaging part 24 on the toner cartridge is in transmission connection with the first driving head 60, and the driving force of the first driving head 60 is transmitted to the toner cartridge, the toner conveying device in the toner cartridge rotates under the action of the driving force and can provide toner for the image forming assembly 30.

[0104] The difference between the embodiment of the application and the embodiment one is that the toner cartridge includes a storage device 22 and a mounting part for mounting the first engaging part 24, that is, the first engaging part 24 is no longer integrated on the shell 21 of the toner cartridge. For example, the first engaging part 24 is integrated on the adapter, and when the toner cartridge needs to be inserted into the installation cavity, the adapter can be installed on the toner cartridge, so as to install the first engaging part 24 on the toner cartridge.

[0105] Further, the adapter further includes the first positioning part 23, and the first positioning part 23 is configured to, when the toner cartridge with the first engaging part 24 and the first mounting part is inserted into the installation cavity and installed in place, the first positioning part 23 cooperates with the first positioning matching part 11 to position the first engaging part 24, so that the first engaging part 24 is in transmission connection with the first driving head 60. Further, the adapter further includes the first positioning part 23, and the first positioning part 23 is configured to, when the toner cartridge with the first engaging part 24 and the first mounting part is inserted into the installation cavity and installed in place, the first positioning part 23 cooperates with the first positioning matching part 11 to position the first engaging part 24, so that the first engaging part 24 is in transmission connection with the first driving head 60.

[0106] When the cartridge is inserted into the body 10 and installed in place, the second conductive contact 222 of the cartridge is in contact with the first conductive contact 50, and forms a plurality of contact points. The maximum distance of any two contact points in the transverse cross section of the body 10 (the distance H in the figure) is less than or equal to the maximum width of the outermost profile of the first positioning portion 23 in the transverse cross section of the body 10 (the width D in the figure).

[0107] In this way, the influence of the driving force from the first driving head 60 on the contact between the first conductive contact 50 and the second conductive contact 222 can be reduced, so as to avoid relative movement between the first conductive contact 50 and the second conductive contact 222, and to make the contact between the first conductive contact 50 and the second conductive contact 222 more stable, thereby ensuring normal operation of the image forming apparatus 100.

[0108] On the basis of the above embodiment, the adapter provided in the embodiment of the present application not only includes the first positioning portion 23, but also includes the first engaging portion 24.

[0110] In this way, the influence of the driving force from the first driving head 60 on the contact between the first conductive contact 50 and the second conductive contact 222 can be further reduced, so as to avoid relative movement between the first conductive contact 50 and the second conductive contact 222, and to make the contact between the first conductive contact 50 and the second conductive contact 222 more stable, thereby ensuring normal operation of the image forming apparatus 100.

[0111] In another embodiment, the adapter includes a first fixing portion configured to detachably dispose the first positioning portion 23 on the housing 21 of the cartridge, and a second fixing portion configured to detachably dispose the first engaging portion 24 on the housing 21 of the cartridge, i.e., the first fixing portion and the first engaging portion 24 can be detachably installed on the housing 21 of the cartridge respectively.
