[0001] The present application relates to the technical field of image forming equipment, and in particular to a chip holder, a powder box, a powder box assembly and an image forming equipment. Background Art

[0002] An image forming device is a device that forms an image on a medium through an imaging processing technology. For example, a printer, a copier, etc. The image forming device includes a main body and at least one powder box, wherein a printing component is arranged in the main body, and the powder box includes a chip electrically connected to the printing component. When the powder box is inserted into the main body and installed in place, the chip is electrically connected to the printing component and can provide the printing component with toner for printing.

[0003] Exemplarily, the image forming device includes a drawer, the powder box is placed in the drawer, and the drawer can be inserted into the main body; the chip has a conductive contact, and the printing component includes a conductive spring, which is located in the main body and arranged opposite to the conductive contact. When the drawer is inserted into the main body and installed in place, the conductive spring contacts the conductive contact and can transmit signals. However, during the insertion of the powder box, the force of the conductive spring acts on the powder box, causing the drawer to get stuck during the insertion process, and even damaging the conductive spring, affecting the user experience. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a chip holder, a powder box, a powder box assembly and an image forming device, which can avoid jamming during the drawer insertion process, reduce the risk of damage to the conductive spring sheet, and improve the user experience.

[0005] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0006] A first aspect of an embodiment of the present application provides a chip holder, which is installed on a powder box, and the chip holder is used to install a chip; the chip holder includes a bearing surface and a guide slope; along the insertion direction of the powder box, the guide slope is located in front of the bearing surface, and the chip is installed on the bearing surface; one side of the guide slope is connected to the bearing surface, and the other side of the guide slope gradually tilts inward along the insertion direction of the powder box.

[0009] During the powder box insertion process, the side of the guide slope away from the bearing surface contacts the conductive spring sheet first; as the powder box continues to be inserted, the conductive spring sheet gradually slides along the guide slope to the bearing surface and can be electrically connected to the chip disposed on the bearing surface to complete the communication connection between the powder box and the image forming device. During this process, the elastic force of the chip holder from the conductive spring sheet gradually increases.

During the powder box insertion process, the guide slope contacts the conductive spring sheet before the bearing surface, so that the elastic force from the conductive spring sheet on the chip holder gradually increases, thereby avoiding jamming caused by the instantaneous increase in the force from the conductive spring sheet on the powder box, ensuring a smooth insertion process and reducing the risk of damage to the conductive spring sheet.

[0016] In a possible implementation, the guide block is detachably mounted on the body; or the body and the guide block are an integral structure, and the bearing surface and the guide inclined surface are both formed on the same inclined surface.

[0018] A third aspect of an embodiment of the present application provides a powder box set, comprising a plurality of powder boxes according to the second aspect, wherein the guide slopes of at least two of the plurality of powder boxes have different extension lengths along the insertion direction thereof.

[0019] In a possible implementation, among the plurality of powder boxes, along the insertion direction of the powder boxes, the extension lengths of the guide slopes of the plurality of powder boxes in the insertion direction increase sequentially.

[0049] In the image forming device in the related art, when the powder box is inserted into the body along with the drawer, there is a problem that the drawer is stuck due to the force of the conductive spring sheet, or even the conductive spring sheet is damaged. The inventor has found that the reason for this problem is:

[0050] When the powder box is inserted into the image forming device along with the drawer, the conductive spring is in direct contact with the bearing surface of the chip holder, and the force acting on the powder box from the conductive spring increases instantly. This force is perpendicular to the insertion direction of the powder box, causing the drawer to get stuck during the insertion process, and even damaging the conductive spring.

[0051] In response to the above technical problems, an embodiment of the present application provides a chip bracket, in which a guide bevel is provided on one side of the bearing surface, and the guide bevel is located on the front side of the bearing surface along the insertion direction of the powder box; one side of the guide bevel is connected to the bearing surface, and the other side of the guide bevel gradually tilts inward along the insertion direction.

[0052] During the powder box insertion process, the side of the guide slope away from the bearing surface contacts the conductive spring sheet first; as the powder box continues to be inserted, the conductive spring sheet gradually slides along the guide slope to the bearing surface, and can be electrically connected to the chip set on the bearing surface to complete the communication connection between the powder box and the image forming device. During this insertion process, the elastic force of the conductive spring sheet gradually increases on the chip holder. This arrangement can avoid the jamming caused by the instantaneous increase in the force of the conductive spring sheet on the powder box, ensure a smooth insertion process, and reduce the risk of damage to the conductive spring sheet.

[0053] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0054] To facilitate the description of the embodiments of the present application, the coordinate system in the accompanying drawings is first explained, wherein the X-axis direction is a first direction, the first direction is the insertion direction of the powder box, for example, this direction may be the front and rear directions of the powder box; the Y-axis direction is a third direction, for example, the third direction is the length extension direction of the powder box, that is, the left and right directions of the powder box; the Z-axis direction is a second direction, for example, the second direction is perpendicular to the insertion direction of the powder box, this direction may be the upper and lower directions of the powder box.

[0055] like Figure 1 and Figure 2 As shown, the image forming device 200 provided in the embodiment of the present application may be one of a printer and a copier, etc., and the embodiment of the present application is not limited to this. The image forming device 200 includes a powder box set 100, a main body (not shown in the figure) and a printing component, wherein the powder box set 100 may include at least one powder box 101, and the powder box 101 stores toner and is used to provide toner to the printing component. Since the powder box 101 needs to be replaced after being used for a long time, the powder box 101 can be detachably installed in the main body.

[0056] Preferably, the powder box set 100 of the embodiment of the present application includes a plurality of powder boxes 101, and the plurality of powder boxes 101 are installed on the same drawer (not shown in the figure), and are inserted into the main body along with the drawer, so as to improve the installation efficiency of the powder box set 100. For example, the main body is provided with an installation cavity, and the installation cavity is matched with the drawer where the powder box set 100 is located to ensure that the drawer can be inserted into the main body.

[0057] Further, the printing assembly is disposed in the installation cavity, and the printing assembly includes a conductive spring 210 electrically connected to each powder box 101; the powder box 101 is provided with a chip 20, and the chip 20 has a plurality of conductive contacts 21, and the conductive contacts 21 are used to contact and electrically connect with the conductive spring 210. It should be noted that the chip 20 of each powder box 101 includes a plurality of conductive contacts 21, and the plurality of conductive contacts 21 can selectively contact with a plurality of conductive springs 210 respectively to complete the transmission of different signals.

[0058] like Figures 3 to 6As shown, the powder box 101 provided in the embodiment of the present application includes a shell 30, a chip 20 and a chip holder 10, and the chip holder 10 is used to install the chip 20, and the chip holder 10 is arranged on the shell 30. For example, along the third direction, the chip holder 10 is detachably connected to the end of the shell 30, and when the powder box 101 is inserted into the main body, the chip holder 10 is opposite to the conductive spring sheet 210, and the conductive contact 21 of the chip 20 can contact the conductive spring sheet 210.

[0059] Specifically, the chip holder 10 includes a bearing surface 10a and a guide slope 10b, wherein along the insertion direction of the powder box 101, the guide slope 10b is located in front of the bearing surface 10a, and the guide slope 10b and the bearing surface 10a are arranged so that the chip holder 10 faces the conductive elastic sheet 210. During the insertion process of the powder box 101, the guide slope 10b contacts the conductive elastic sheet 210 first, and as the powder box 101 continues to be inserted, the conductive elastic sheet 210 passes the guide slope 10b and contacts the bearing surface 10a.

[0060] Along the insertion direction (first direction) of the powder box 101, one side of the guide slope 10b is connected to the bearing surface 10a, and the guide slope 10b and the bearing surface 10a have a smooth transition. The other side of the guide slope 10b gradually tilts inward along the first direction. The so-called "inside" is relative to the main body. The outer side of the chip holder 10 is the cavity wall of the installation cavity, or the conductive spring 210; the inner side is the shell 30 where the chip holder 10 is located; in other words, the side of the guide slope 10b away from the bearing surface 10a is gradually away from the conductive spring 210.

[0061] During the insertion process of the powder box 101, the side of the guide slope 10b away from the bearing surface 10a contacts the conductive spring 210 first; as the powder box 101 continues to be inserted, the conductive spring 210 gradually slides along the guide slope 10b to the bearing surface 10a, and can be electrically connected to the chip 20 disposed on the bearing surface 10a, so as to complete the communication connection between the powder box 101 and the image forming device. During this process, the elastic force of the conductive spring 210 on the chip holder 10 gradually increases.

[0062] In the prior art, when the powder box is inserted into the image forming device along with the drawer, the conductive spring is in direct contact with the bearing surface of the chip holder, and the force acting on the powder box from the conductive spring increases instantly. This force is perpendicular to the insertion direction of the powder box, which causes the drawer to get stuck during the insertion process and even damages the conductive spring.

[0063] However, in the embodiment of the present application, a guiding slope 10b is provided on the front side of the chip holder 10. During the insertion process of the powder box 101, the guiding slope 10b contacts the conductive spring 210 before the bearing surface 10a, so that the elastic force from the conductive spring 210 on the chip holder 10 gradually increases, thereby avoiding jamming caused by the instantaneous increase in the force from the conductive spring 210 on the powder box 101, ensuring a smooth insertion process of the powder box 101 and reducing the risk of damage to the conductive spring 210.

[0064] On the basis of the above embodiments, the chip holder 10 provided in the embodiment of the present application includes a body 11 and a guide block 12, and the guide block 12 is arranged on the front side of the body 11 along the insertion direction of the powder box 101. The bearing surface 10a is arranged on the body 11, part of the bearing surface 10a is used to install the chip 20, and the guide inclined surface 10b is located on the guide block 12.

[0065] Furthermore, the guide slope 10b and the bearing surface 10a are configured as the surface of the chip holder 10 facing the conductive spring 210. During the insertion of the powder box 101, the guide block 12 contacts the conductive spring 210 before the body 11, and as the powder box 101 is inserted, the conductive spring 210 moves to the bearing surface 10a through the guide slope 10b.

[0066] In detail, the moving path of the conductive spring 210 relative to the chip holder 10 of the embodiment of the present application extends along the first direction, and the guide slope 10b has a certain width along the first direction. In order to fully describe the guide slope 10b, the arrangement of the guide slope 10b in the second direction is described below, and the second direction is perpendicular to the insertion direction of the powder box 101.

[0067] Continue reading Figure 3 , along the second direction, the guide slope 10b at least includes a first portion 10b1 and a second portion 10b2, and the first portion 10b1 and the second portion 10b2 are arranged in a stepped manner, that is, along the second direction, the first portion 10b1 and the second portion 10b2 are arranged in sections, such as Figure 3 As shown, the first part 10b1 is arranged below the second part 10b2; along the first direction, the first part 10b1 can be arranged in front of or behind the second part 10b2.

[0068] Furthermore, the chip 20 includes a plurality of conductive contacts 21, which are arranged in columns or rows; along the insertion direction of the powder box 101, the arrangement direction of the plurality of conductive contacts 21 is consistent with the second direction. The first portion 10b1 and the second portion 10b2 correspond to at least one conductive contact 21 respectively; in other words, the first portion 10b1 and the second portion 10b2 may correspond to different conductive springs 210.

[0069] When the powder box 101 is inserted into the main body, when the conductive spring piece 210 corresponding to each chip 20 contacts its corresponding guide slope 10b, the front part of the slope (such as the first part 10b1) contacts the conductive spring piece 210 first, and the rear part of the slope (such as the second part 10b2) contacts the conductive spring piece 210 later.

[0070] With such a configuration, during the insertion process of each powder box 101, the first part 10b1 and the second part 10b2 contact the corresponding conductive spring at different times, and the force exerted by the conductive spring 210 decreases gradually as a whole, and gradually increases during the insertion process. It is understandable that the push force of the drawer can be reduced in proportion, for example, it can be reduced to half of the original force, so that the drawer insertion is smoother.

[0071] Continue reading Figure 4 The chip 20 includes four conductive contacts 21, and the four conductive contacts 21 are arranged at intervals along the second direction. The guiding slope 10b is arranged at the front side of the bearing surface 10a along the first direction, that is, the guiding slope 10b is located at the front side of the chip 20. The guiding slope 10b is arranged at intervals along the second direction. There are four sections, and the four sections are arranged in a step-like manner. Each section corresponds to a conductive contact 21, and each section corresponds to a conductive spring 210 accordingly.

[0072] When the powder box 101 is inserted into the main body, when the conductive spring piece 210 corresponding to each powder box 101 contacts the guide inclined surface 10b, each conductive spring piece 210 of the plurality of conductive spring pieces 210 contacts each inclined surface in turn during the insertion process.

[0073] With such a configuration, during the insertion process of each powder box 101, the timing of contact between the guide slopes of different sections and the corresponding conductive springs is different, and the force exerted by the conductive springs 210 decreases gradually as a whole, and gradually increases during the insertion process. It is understandable that the push force of the drawer can be reduced in proportion, for example, it can be reduced to one-fourth of the original force, so that the drawer insertion is smoother.

[0074] like Figures 5 to 7 As shown, in another embodiment, along the second direction, the guiding slope 10b is arranged on the guiding block 12, that is, along the second direction, the top of the guiding slope 10b extends to the top of the guiding block 12, and the bottom of the guiding slope 10b extends to the bottom of the guiding block 12. Further, the guiding slope 10b is gradually inclined along the second direction, and during the insertion process of the powder box 101, for each powder box 101, the contact time points of the conductive springs 210 corresponding to the chip 20 at different positions of the guiding slope 10b are different, so that the force of the conductive springs 210 on the chip holder 10 is reduced as a whole, and gradually increases with the insertion process.

[0075] On the basis of the above embodiments, the embodiments of the present application do not limit the connection method between the guide block 12 and the body 11. For example, in one embodiment, the guide block 12 can be detachably mounted on the body 11, the guide block 12 can be manufactured separately, and the guide block 12 with different forms of the guide slope 10b can be replaced as needed, and the guide block 12 can be connected to the body 11 through a snap-fit ​​structure.

[0076] It is understandable that the guide block 12 can be configured as a buffer frame or a guide frame, and can also be detachably installed on the shell 30 of the powder box 101, and can be connected to the body 11 of the chip holder 10 to buffer the force between the conductive spring 210 and the chip holder 10 during the installation of the powder box 101.

[0077] like Figure 8 and Fig. 9 As shown, in another embodiment, the body 11 and the guide block 12 are in an integrated structure, that is, the body 11 and the guide block 12 are both formed on the chip holder 10. For example, the chip holder 10 includes a mounting surface opposite to the guide spring sheet, part of the mounting surface is configured as a bearing surface 10a for mounting the chip 20; part of the mounting surface is configured as a guide inclined surface 10b, and along the insertion direction, the guide inclined surface 10b is located in front of the bearing surface 10a.

[0078] It should be noted that the bearing surface 10a can be a horizontal mounting surface or configured as an inclined surface. Preferably, the bearing surface 10a and the guiding inclined surface 10b are both configured as inclined surfaces, that is, the body 11 and the guiding block 12 are integrally structured, and the bearing surface 10a and the guiding inclined surface 10b are both formed on the same inclined surface.

[0079] Such a configuration can further reduce the elastic force exerted on the chip holder 10 by the conductive spring 210 during the insertion of the powder box 101, thereby avoiding jamming caused by the instantaneous increase in the force exerted on the powder box 101 by the conductive spring 210, thereby ensuring a smooth insertion process of the powder box 101 and reducing the risk of damage to the conductive spring 210.

[0080] Continue reading Figure 1 , and combined with Figures 10 to 13 The powder box set 100 provided in the embodiment of the present application includes a plurality of powder boxes 101 arranged at intervals. Among the plurality of powder boxes 101 in a powder box set 100, the extension lengths of the guide slopes 10b of at least two powder boxes 101 along the insertion direction thereof are different.

[0081] Exemplarily, the powder box set 100 includes four powder boxes 101. For the convenience of describing the embodiment of the present application, the four powder boxes 101 are respectively arranged in sequence: a first powder box 101a, a second powder box 101b, a third powder box 101c and a fourth powder box 101d; along the insertion direction of the powder boxes 101, the first powder box 101a is located at the front end of the powder box set 100, the fourth powder box 101d is located at the rear end of the powder box set 100, the second powder box 101b and the third powder box 101c are arranged in sequence between the first powder box 101a and the fourth powder box 101d, and the second powder box 101b is arranged close to the first powder box 101a, and the third powder box 101c is arranged close to the fourth powder box 101d.

[0082] In the four powder boxes 101, the chip holder 10 corresponding to each powder box 101 is respectively provided with a guiding slope 10b, wherein the extending length of the guiding slope 10b of the first powder box 101a in the first direction is greater than the extending length of the guiding slope 10b of the second powder box 101b in the first direction.

[0083] During the process of inserting the powder box set 100 into the main body, when the conductive spring piece 210 corresponding to the second powder box 101b passes through the guiding inclined surface 10b of the second powder box 101b and contacts the bearing surface 10a of the second powder box 101b, the conductive spring piece 210 corresponding to the first powder box 101a contacts the guiding inclined surface 10b of the first powder box 101a and does not move to the bearing surface 10a of the first powder box 101a. In this way, during the entire process of inserting the powder box set 100 into the main body, the force exerted by the conductive spring piece 210 on the powder box set 100 can be reduced, thereby preventing the drawer where the powder box set 100 is located from getting stuck.

[0084] Preferably, in the embodiment of the present application, among the multiple powder boxes 101, along the insertion direction of the powder boxes 101, the extension lengths of the guide slopes 10b of the multiple powder boxes 101 in the insertion direction thereof increase sequentially.

[0085] For example, the powder box set 100 includes the above-mentioned first powder box 101a, second powder box 101b, third powder box 101c and fourth powder box 101d, the first powder box 101a has a first guide slope, the second powder box 101b has a second guide slope, the third powder box 101c has a third guide slope, and the fourth powder box 101d has a fourth guide slope.

[0086] Along the insertion direction (first direction) of the powder box 101, the extension length of the first guide slope in the first direction is greater than the extension length of the second guide slope in the first direction; the extension length of the second guide slope in the first direction is greater than the extension length of the third guide slope in the first direction; the extension length of the third guide slope in the first direction is greater than the extension length of the fourth guide slope in the first direction.

[0087] When the powder box set 100 is inserted into the main body, when the conductive spring pieces 210 corresponding to some powder boxes 101 move to their bearing surfaces 10a, the conductive spring pieces 210 corresponding to other powder boxes 101 can be kept on the guiding inclined surfaces 10b of the powder boxes 101. This arrangement can greatly reduce the force of the conductive spring pieces 210 on the powder box set 100, and prevent the drawer where the powder box set 100 is located from getting stuck.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
