The developing box includes a chip and a holding portion for mounting the chip, and the holding portion can move in two directions. When the developing box is not installed in the imaging device, the holding portion moves downward under the action of gravity so that the chip can pass the blocking position in the imaging device; after the developing box is installed in the imaging device, the holding portion moves upward under the support of the frame of the imaging device so that the chip contacts the electrical contacts in the imaging device. This holding portion has a complex structure and a high manufacturing cost. Utility Model Content
[0004] The utility model aims to provide a developing box, the chip mounting bracket of the developing box has a simple structure and is easy to produce.
[0005] In order to achieve the above-mentioned purpose, the developer box of the utility model includes a shell for accommodating a developer, a drive assembly and an end cover. The shell has a first side and a second side in a first direction. The drive assembly is located on the first side of the shell. The end cover is detachably mounted on the first side of the shell.

The elastic deformation portion is a flat plate structure, and extends downwardly from the lower side.
[0006] The chip holder of the developer box of the utility model is provided with an elastic deformation part. When the chip holder is pressed by the frame structure of the imaging device during installation of the developer box, the elastic deformation part will be elastically deformed so that the installation part can move downward, so that the chip can pass through the inner wall of the cavity of the imaging device. After the chip passes through the inner wall, the elastic deformation part will elastically restore to the initial state, and the chip on the chip holder can make electrical contact with the electrical contacts in the imaging device. Compared with the movable holder that can move up and down provided in the prior art, the chip holder structure of the developer box of the utility model is simpler and easier to manufacture.

[0008] In one embodiment, the chip holder further includes a cantilever, which extends downward from the lower side of the mounting portion and forms an angle with the elastic deformation portion. When the developing box is installed in the imaging device, the lower end of the cantilever abuts against the frame of the imaging device to support the mounting portion upward, so that the chip on the mounting portion can contact the electrical contacts in the imaging device. The cantilever can ensure that the chip can fully contact the electrical contacts in the imaging device after the developing box is installed in place. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The structure and other aspects of the developer box of the present invention are further described in detail below through specific implementations and with reference to the accompanying drawings.
[0016] like Figure 1 and Figure 2As shown, the developer box of the utility model includes a housing 1, a developing roller 2 and a driving assembly 3, and the housing 1 has a cavity for accommodating a developer. The developing roller 2 is rotatably mounted on the housing 1. Along the axial direction (first direction) of the developing roller 2, the housing 1 has a driving side 11 (first side) and a non-driving side 12 (second side). The driving assembly 3 is arranged at the driving side 11 of the housing 1. The driving assembly 3, for example, includes a coupling for receiving a driving force from an imaging device, a developing roller gear mounted on the end of the developing roller shaft, and a powder feeding roller gear mounted on the end of the powder feeding roller shaft. After the developer box of the utility model is detachably mounted to the imaging device, the driving assembly 3 can receive a driving force from the imaging device and drive the rotatable member on the developer box to rotate. For example, the developing roller 2 or the powder feeding roller (not shown in the figure).
[0017] The developer box of the utility model further includes an end cover 4 and a chip holder 5, wherein the end cover 4 is detachably mounted on the driving side 11 of the housing 1, and the driving assembly 3 is located between the housing 1 and the end cover 4. The chip holder 5 is arranged on the end cover 4. The chip holder 5 is used to mount the chip 6. The chip holder 5 can be integrally formed with the end cover 4, or can be detachably mounted on the side wall of the end cover 4 in a split manner.
[0018] like Figure 3 As shown, the chip holder 5 of the developer box of the utility model further includes a mounting portion 51 and an elastic deformation portion 52, the mounting portion 51 has an upper side 511 and a lower side 512, and the chip 6 is mounted on the upper side 511. In a preferred embodiment, the mounting portion 51 has a groove 513 for accommodating the chip 6 at the upper side 511. The chip 6 is clamped in the groove 513. One end of the elastic deformation portion 52 is connected to the lower side 512 of the mounting portion 51, and the other end is connected to the end cover 4. The elastic deformation portion 52 is a flat plate structure, and extends obliquely relative to the plane where the lower side 512 is located, that is, the angle formed by the plane where the elastic deformation portion 52 is located and the plane where the lower side 512 is located is non-right angle. In a preferred embodiment, the chip holder 5 includes a fixing portion 53, one end of the elastic deformation portion 52 is connected to the lower side 512, and the other end is connected to the fixing portion 53. The fixing portion 53 is mounted on the end cover 4 in a detachable manner, that is, the chip holder 5 is mounted on the end cover 4 in a detachable manner.
[0019] The developing box of the utility model is installed in the cavity of the imaging device. The inner wall 80 of the cavity (frame of the imaging device) has an irregular structure. For a specific type of imaging device, the developing box will hit the inner wall 80 at a local position when entering the cavity, such as Figure 3As shown. The chip 6 needs to pass over the local structure of the inner wall 80 before it can make electrical contact with the electrical contact 81 in the imaging device. When the chip holder of the developer box of the utility model is used and the developer box is installed in the imaging device, the elastic deformation portion 52 of the chip holder 5 will be elastically deformed after being pressed by the inner wall 80, so that the mounting portion 51 moves downward, so that it can pass the position of the inner wall 80. When the chip 6 passes over the position of the inner wall 80, the elastic deformation portion 52 will elastically return to the initial state, so that the chip on the chip holder 5 can make electrical contact with the electrical contact 81 in the imaging device.
[0020] like Figures 4 to 6 As shown, according to another embodiment, the chip holder 5 of the developer box of the utility model is further provided with a cantilever 54, which extends downward from the lower side 512 of the mounting portion 51 and forms an angle with the elastic deformation portion 52. Figures 1 to 3 In the chip holder 5 of the embodiment shown, although the chip 6 can pass over the inner wall of the imaging device to reach the position of the electrical contact 81, the chip 6 cannot fully contact the electrical contact 81 after the elastic deformation portion 52 is deformed. A possible reason is, for example, that the elastic deformation portion 52 has a large deformation amount and cannot be completely restored to the initial position. For this reason, a cantilever 54 is further provided on the chip holder 5 of the developer box of the utility model. When the developer box is installed on the imaging device, the movable end of the cantilever 54 can abut against the mounting track 82 of the imaging device, and the cantilever 54 can support the mounting portion 51 upward so that the chip 6 can fully contact the electrical contact 81.
[0021] Compared with the movable bracket provided in the prior art, the chip bracket structure of the developer box of the utility model is simpler and also easier to produce.
[0022] The above embodiments are only used to illustrate the concept and scope of the utility model, and are not used to limit the protection scope of the utility model. Modifications, equivalent substitutions and other improvements to the above embodiments that are obvious to those skilled in the art are also within the concept of the utility model. The protection scope and concept of the utility model are specifically defined by the claims.
