Description

Technical Field

[0001] The utility model relates to the field of electronic photographic imaging, in particular to a chip seat component and a powder box. Background Art

[0002] An electrophotographic imaging device is a device that uses the principle of electrophotography to form an image on a printing medium such as paper, including a printer and a powder box that is detachably installed in the printer. The powder box is usually provided with a chip for electrically connecting with the imaging device to transmit signals, and the chip is installed in the chip seat.

[0003] There is an existing chip seat on a powder box, which includes a first holding part, a second holding part, and a coil spring. The chip is mounted on the surface of the first holding part, and two protrusions are provided on the outer surface of the first holding part, which can pass through the end cover to provide support and guidance.

[0004] When the developer box is assembled into the imaging device, the chip holder will move to the position where the electrical contacts of the imaging device are electrically connected. During the process of electrical contact between the chip holder and the electrical contacts, the chip holder needs to be moved by the undulating surface on the imaging device and the elastic parts in the chip holder simultaneously. Therefore, during the process of the chip holder and the imaging device being installed together, jamming, installation difficulties, unstable electrical contact of the chip and the like may occur, resulting in unstable electrical connection between the chip and the imaging device, causing the imaging device to be unable to recognize the initial information of the consumable box, such as the model, color, toner capacity, production date and manufacturer code of the powder box, and imaging auxiliary information, such as data recording the remaining amount or consumption of the consumables.

[0005] Therefore, the user needs to accurately push the developing box and the drum frame into the imaging device smoothly, which greatly increases the user's operating difficulty and affects the user's experience. Utility Model Content

[0006] The first object of the utility model is to provide a chip seat assembly which can improve the smoothness of installation and improve the stability of the connection between the chip and the electrical contacts of the imaging device.

[0007] The second object of the utility model is to provide a powder box having the above-mentioned chip seat assembly.

[0008] To achieve the above-mentioned first purpose, the utility model provides a chip seat assembly, including: a chip seat, a first force-bearing part, a chip mounting part and a guide part are arranged on the chip seat, and a chip is arranged at the chip mounting part; a driving member, the driving member is provided with a second force-bearing part and a force-applying part; a shell, the shell is provided with a mounting cavity, the chip seat is located in the mounting cavity, the second force-bearing part is exposed from the shell, a guide rail is arranged on the side wall of the shell, the guide rail extends along the normal direction of the electrical contact surface of the chip, and the guide part slides with the guide rail; an elastic reset member, the elastic reset member drives the driving member to reset under the action of its own elastic restoring force; the second force-bearing part forces the driving member to rotate after being subjected to the force, and the force-applying part of the driving member applies a thrust force to the first force-bearing part of the chip seat, and the first force-bearing part drives the chip seat to move from a retracted position to an extended position along the guide rail; after the force applied to the second force-bearing part is cancelled, the elastic reset member can force the driving member to rotate in the opposite direction, and the chip seat moves from an extended position to a retracted position along the guide rail under the action of its own gravity.

[0009] It can be seen from the above scheme that, through the cooperation between the chip holder and the driving member, when the second force-bearing part is subjected to the force, the driving member is forced to rotate, and the force-applying part of the driving member applies a thrust to the first force-bearing part of the chip holder, and the first force-bearing part drives the chip holder to move from the retracted position to the extended position along the guide rail. After the force applied to the second force-bearing part is cancelled, the elastic reset member can force the driving member to rotate in the opposite direction, and the chip holder moves from the extended position to the retracted position along the guide rail under the action of its own gravity.

[0010] Since the chip and the chip holder are in the retracted position under the action of their own gravity and the elastic reset member in the initial state of the powder box installation, the chip holder will not interfere with other parts of the imaging device during the powder box installation process, and the electrical contacts of the chip can be smoothly electrically connected to the electrical contact parts of the imaging device. After the powder box is installed, the chip and the chip holder remain in the extended position, thereby achieving a stable electrical connection with the electrical contact parts of the imaging device.

[0011] A preferred solution is that the first force-bearing part includes a first hinge hole and a second hinge hole arranged coaxially; the force-applying end of the driving member is provided with an axial hole, and the chip seat assembly also includes a hinge shaft, which passes through the first hinge hole, the axial hole and the second hinge hole in sequence, and the force-applying part is located at both ends of the hinge shaft; the elastic reset member is sleeved on the hinge shaft and is located between the first hinge hole and the axial hole; the first end of the elastic reset member cooperates with the driving member to limit the position in the direction of rotation of the driving member, and the second end of the elastic reset member cooperates with the chip seat to limit the position in the direction of rotation of the driving member.

[0012] It can be seen that the driving member and the chip holder are hinged by the hinge shaft. When the second force-bearing part of the driving member is subjected to external force, the driving member pushes the chip holder upward to the extended position while rotating relative to the chip holder, so as to achieve electrical connection with the electrical contact part of the imaging device. Under the action of the elastic reset member, the driving member and the chip holder are elastically connected, thereby avoiding damage to the driving member caused by hard contact between the driving member and the chip holder.

[0013] A further solution is that the second force-bearing portion is curved in an arc shape.

[0014] It can be seen that the arc-shaped second force-bearing portion can more easily receive the force and avoid scratches on the contact position.

[0015] A further solution is that the chip seat is provided with a supporting protrusion, the first hinge hole is provided on the supporting protrusion, and a first mounting groove is also provided on the supporting protrusion. The first mounting groove is located on the side of the first hinge hole close to the second hinge hole, and a first limiting groove is provided in the first mounting groove. The first limiting groove extends along the tangential direction of the elastic return member, and the first spring arm of the elastic return member extends into the first limiting groove.

[0016] It can be seen that the provision of the first mounting groove enables the elastic reset member to be positioned relative to the chip seat, and the first spring arm of the elastic reset member to be positioned.

[0017] A further solution is that a second mounting groove is provided on the driving member, the second mounting groove is recessed inward from the side wall of the driving member along the axial direction of the second hinge hole, a second limiting groove is provided in the second mounting groove, the second limiting groove extends along the tangential direction of the elastic return member, and the second spring arm of the elastic return member extends into the second limiting groove.

[0018] It can be seen that the provision of the second mounting groove enables the elastic return member to be positioned relative to the driving member, and the second spring arm of the elastic return member to be positioned.

[0019] A preferred solution is that the second force-bearing part and the force-applying part are respectively located at two ends of the driving member, a hinge shaft is provided in the middle of the driving member, an axial hole is opened on the outer shell, and the hinge shaft and the axial hole are rotatably matched; the elastic reset member is sleeved on the hinge shaft, and both ends of the elastic reset member are matched with the outer shell to limit the rotation direction of the driving member.

[0020] It can be seen that the driving member and the housing are hinged by the hinge shaft, the second force-bearing part and the force-applying part are respectively located at two ends of the driving member, and the chip holder is driven to move by the lever principle.

[0021] A further solution is that the driving member includes a first driving section and a second driving section which are set at an obtuse angle, the first driving section and the second driving section are arranged along the normal of the electrical contact surface of the chip, and the second driving section is closer to the chip than the first driving section; the hinge shaft is set on the first driving section and close to the connection position between the first driving section and the second driving section; the second force-bearing portion is located at the free end of the second driving section, and the force-applying portion is located at the free end of the first driving section.

[0022] It can be seen that by setting the first driving section and the second driving section of the driving member to form an obtuse angle, the positions of the abutment member and the electrical contact component that apply force to the second force applying portion in the imaging device can be better adapted.

[0023] A further solution is that at least one elastic reset member is respectively provided on both sides of the driving member.

[0024] It can be seen that the multiple elastic reset members can ensure the smooth reset of the driving member.

[0025] A preferred solution is that the first force-bearing portion is a groove, and the force-applying portion can extend into the groove.

[0026] This shows that the first force-bearing part and the force-applying part can cooperate better.

[0027] To achieve the above second purpose, the utility model provides a powder box, including a box body and the above chip seat assembly, wherein the outer shell is fixedly connected to the box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0045] The driving member 4 is provided with a second force-bearing portion 41 and a force-applying portion 42, the housing 5 is provided with an installation cavity 50, the chip holder 3 and the driving member 4 are both located in the installation cavity 50, the second force-bearing portion 41 is exposed to the housing 5, and in the installation direction of the powder box, the second force-bearing portion 41 is located on the downstream side of the chip holder assembly 2, and a guide rail 51 is provided on the side wall of the housing 5, the guide rail 51 extends along the normal direction of the electrical contact surface 61 of the chip 6, and the guide portion 33 is slidably matched with the guide rail 51. The second force-bearing portion 41 is curved in an arc shape. Another guide protrusion 35 is also provided on the side of the chip holder 3 opposite to the guide portion 33, and a slide groove 10 parallel to the guide rail 51 is provided on the box body, and the guide protrusion 35 is slidably matched with the slide groove 10.

[0046] See also Figures 5 to 7 The first force-bearing part 31 includes a first hinge hole 311 and a second hinge hole 312 arranged coaxially, the force-applying end of the driving member 4 is provided with an axial hole 40, the chip seat assembly 2 also includes a hinge shaft 20, the hinge shaft 20 passes through the first hinge hole 311, the axial hole 40 and the second hinge hole 312 in sequence, the force-applying part 42 is located at both ends of the hinge shaft 20, the elastic reset member 9 is a spring, the elastic reset member 9 is sleeved on the hinge shaft 20 and is located between the first hinge hole 311 and the axial hole 40.

[0047] The first end of the elastic reset member 9 cooperates with the upper limit position of the driving member 4 in the direction of rotation of the driving member 4, and the second end of the elastic reset member 9 cooperates with the upper limit position of the chip holder 3 in the direction of rotation of the driving member 4. The elastic reset member 9 can drive the above-mentioned driving member 4 to reset under the action of its own elastic restoring force.

[0048] The chip holder 3 is provided with a supporting protrusion 34, and the first hinge hole 311 is provided on the supporting protrusion 34. The supporting protrusion 34 is also provided with a first mounting groove 341, and the first mounting groove 341 is located on the side of the first hinge hole 311 close to the second hinge hole 312. A first limiting groove 342 is provided in the first mounting groove 341, and the first limiting groove 342 extends along the tangential direction of the elastic reset member 9, and the first spring arm 91 of the elastic reset member 9 extends into the first limiting groove 342. A second mounting groove 43 is provided on the driving member 4, and the second mounting groove 43 is recessed inwardly from the side wall of the driving member 4 along the axial direction of the second hinge hole 312, and a second limiting groove 44 is provided in the second mounting groove 43, and the second limiting groove 44 extends along the tangential direction of the elastic reset member 9, and the second spring arm 92 of the elastic reset member 9 extends into the second limiting groove 44.

[0049] The second force-bearing portion 41 forces the driving member 4 to rotate after receiving the force, and the force-applying portion 42 of the driving member 4 applies a thrust to the first force-bearing portion 31 of the chip holder 3, and the first force-bearing portion 31 drives the chip holder 3 to move from the retracted position to the extended position along the guide rail 51. After the force applied to the second force-bearing portion 41 is cancelled, the elastic reset member 9 can force the driving member 4 to rotate in the opposite direction, and the chip holder 3 moves from the extended position to the retracted position along the guide rail 51 under the action of its own gravity.

[0050] See also Figures 2 to 4 , when the user installs the powder box to the imaging device, the chip holder 3 is at the lowest end of the guide rail 51 under the action of its own gravity and the elastic force of the elastic reset member 9. At this time, the chip holder 3 and the chip 6 are in the retracted position. During the installation of the powder box, the chip holder 3 will not interfere with the other parts of the imaging device and can smoothly approach the electrical contact parts of the imaging device (not shown). Then, when the powder box is about to be assembled in place, the second force-bearing part 41 of the driving member 4 contacts the first abutment member 101 in the imaging device, and the first abutment member 101 is close to the lower side of the chip holder assembly 2. The driving member 4 no longer moves horizontally with the powder box. At this time, when the user continues to push the powder box to the drop position, the driving member 4 rotates around the hinge shaft 20 and applies an upward thrust to the chip holder 3. The chip holder 3 rises along the guide rail 51 and gradually approaches the electrical contact parts of the imaging device until it moves to the extended position and remains in the extended position, so that the chip 6 can be close to the electrical contact parts of the imaging device, thereby forming a stable electrical connection. At this time, the elastic reset member 9 is in a power storage state.

[0051] When the processing box is taken out from the imaging device, the powder box drives the shell 5 and the chip holder 3 to move outward, and the force applied to the second force-bearing part 41 is cancelled. The elastic reset member 9 can force the driving member 4 to rotate in the opposite direction. Under the action of its own gravity, the chip holder 3 moves from the extended position to the retracted position along the guide rail 51, and at the same time, the driving member 4 is reset.

[0052] As can be seen from the above, through the cooperation between the chip holder and the driving member, along with the installation action of the powder box, the chip holder can move between the extended position and the retracted position along the guide rail. Since in the initial state of the powder box installation, the chip and the chip holder are in the retracted position under the action of their own gravity and the elastic reset member, at this time, during the installation process of the powder box, the chip holder will not interfere with other parts of the imaging device, and the electrical contacts of the chip can be smoothly electrically connected to the electrical contact parts of the imaging device. After the powder box is installed, the chip and the chip holder remain in the extended position, thereby achieving a stable electrical connection with the electrical contact parts of the imaging device.

[0053] Chip holder assembly and powder box second embodiment:

[0054] As an explanation of the second embodiment of the chip holder assembly and the powder box of the utility model, only the differences from the first embodiment of the chip holder assembly and the powder box described above are explained below.

[0055] See also Figures 8 to 13 In this embodiment, the second force receiving portion 241 and the force applying portion 242 are respectively located at the two ends of the driving member 24, a hinge shaft 240 is provided in the middle of the driving member 24, and a shaft hole 251 is provided on the housing 25, and the hinge shaft 240 is rotatably matched with the shaft hole 251. The elastic reset member 29 is sleeved on the hinge shaft 240, and both ends of the elastic reset member 29 are matched with the housing 25 in the direction of rotation of the driving member 24. At least one elastic reset member 29 is respectively provided on both sides of the driving member 24.

[0056] The driving member 24 includes a first driving section 243 and a second driving section 244 arranged at an obtuse angle. When the chip holder 23 is in the retracted position, the first driving section 243 and the second driving section 244 are arranged along the normal direction of the electrical contact surface 261 of the chip 26, and the second driving section 244 is closer to the chip 26 than the first driving section 243. The hinge shaft 240 is arranged on the first driving section 243 and close to the connection position between the first driving section 243 and the second driving section 244. The second force receiving portion 241 is located at the free end of the second driving section 244, and the force applying portion 242 is located at the free end of the first driving section 243.

[0057] In addition, the first force receiving portion 231 is a groove, and the force applying portion 242 can extend into the groove.

[0058] When the user installs the powder box into the imaging device, the chip holder 23 is at the lowest end of the guide rail 251 under the action of its own gravity and the elastic force of the elastic reset member 29. At this time, the chip holder 23 and the chip 26 are in the retracted position. During the installation of the powder box, the chip holder 23 will not interfere with the other components of the imaging device and can smoothly approach the electrical contact components (not shown) of the imaging device. Next, when the powder box is about to be assembled in place, the second force-bearing portion 241 of the driving member 24 contacts the second abutment member 102 in the imaging device, and the second abutment member 102 is close to the upper side of the chip holder assembly. At this time, the driving member 24 no longer moves horizontally with the powder box. At this time, when the user continues to push the powder box to the drop position, the driving member 24 rotates around the hinge shaft 240, and the force-applying portion 242 extends into the groove serving as the first force-bearing portion 231. The force-applying portion 242 applies an upward thrust to the chip holder 23. The chip holder 23 rises along the guide rail 251 and gradually approaches the electrical contact component of the imaging device until it moves to the extended position and remains in the extended position, so that the chip 26 can be close to the electrical contact component of the imaging device, thereby forming a stable electrical connection. At this time, the elastic reset member 29 is in a force storage state.

[0059] When the processing box is taken out from the imaging device, after the powder box drives the shell 25 and the chip holder 23 to move outward, after the force applied to the second force-bearing part 241 is cancelled, the elastic reset member 29 can force the driving member 24 to rotate in the opposite direction, and the force-applying part 242 moves in the direction away from the first force-bearing part 231. Under the action of its own gravity, the chip holder 23 moves from the extended position to the retracted position along the guide rail 251, and at the same time, the driving member 24 is reset.

[0060] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
