Abstract
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 first guide part are provided on the chip seat, and a chip is provided at the chip mounting part; a driving seat, the driving seat is provided with a second force-bearing part, a force-applying part and a second guide part; a shell, the shell is provided with a mounting cavity, the chip seat and the driving seat are both located in the mounting cavity, and the second force-bearing part is exposed from the shell; the side wall of the shell is provided with a first guide rail and a second guide rail, the first guide rail extends along the normal direction of the electrical contact surface on the chip, and the extension direction of the second guide rail intersects with the extension direction of the first guide rail; the first guide part slides with the first guide rail, and the second guide part slides with the second guide rail; after the second force-bearing part is subjected to the force, it drives the driving seat to move along the extension direction of the first guide rail, the force-applying part applies the force to the first force-bearing part, and the first force-bearing part drives the chip seat to move along the second guide rail from the retracted position to the extended position.
[0009] It can be seen from the above scheme that through the cooperation between the chip seat and the driving seat, when the second force-bearing part of the driving seat is subjected to external force, under the cooperation of the second guide part and the second guide rail, the driving seat moves relative to the outer shell along the extension direction of the second guide rail. Along with the movement of the driving seat relative to the outer shell, the force-applying part of the driving seat applies a force to the first force-bearing part of the chip seat, thereby driving the chip seat to move relative to the outer shell along the extension direction of the first guide rail to the extended position.
[0010] Since the chip and the chip holder are in the retracted position under their own gravity 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 magnet, the force-applying part includes a second magnet, and the magnetic poles of the first magnet and the second magnet on opposite sides are the same.
[0012] It can be seen that by arranging the first magnet of the chip holder opposite to the side with the same magnetic pole as the second magnet of the drive holder, when the drive holder moves relative to the housing so that the second magnet approaches the first magnet, the repulsive force between the two causes the chip holder to gradually move away from the drive holder along the extension direction of the first guide rail and approach the electrical contact component of the imaging device. When the powder box is assembled in place, the first magnet and the second magnet are arranged opposite to each other, and the repulsive force generated between the two is large enough to keep the chip and the chip holder in the extended position and close to the electrical contact component to form a stable electrical connection.
[0013] A further solution is that a first receiving groove is formed on the chip seat, and the first magnet is arranged in the first receiving groove; a second receiving groove is formed on the drive seat, and the second magnet is arranged in the second receiving groove.
[0014] This shows that accurate positioning of the magnet can be achieved.
[0015] A further solution is that, in the extended position, the first magnet and the second magnet are arranged opposite to each other in the extension direction of the first guide rail.
[0016] It can be seen that this enables the repulsive force between the two to be large enough when in the extended position.
[0017] A preferred solution is that the first force-bearing part includes a first sliding mating surface and a second sliding mating surface, and the first sliding mating surface and the second sliding mating surface are both inclined relative to the extension direction of the first guide rail; the force-applying part includes a first sliding contact surface and a second sliding contact surface, and the angle between the first sliding contact surface and the extension direction of the first guide rail is greater than the angle between the second sliding contact surface and the extension direction of the first guide rail; the first sliding mating surface can slide with the first sliding contact surface, and the second sliding mating surface can slide with the second sliding contact surface; as the second guide part slides along the second guide rail, the first sliding mating surface contacts and slides relatively with the first sliding contact surface, and after the chip holder moves to the first position along the first guide rail toward the extended position, the second sliding contact surface contacts and slides relatively with the second sliding mating surface, and the first sliding mating surface separates from the first sliding contact surface until the chip holder moves to the extended position.
[0018] It can be seen that by setting the sliding contact surface and the sliding matching surface for sliding fit, the driving seat can force the chip seat to be pushed out to the extended position during the installation process of the powder box. In addition, by setting two sliding contact surfaces with different inclination angles, it is ensured that the chip seat rises slowly in the initial stage to avoid interference with other components in the imaging device.
[0019] A further solution is that the second sliding contact surface and the second sliding fitting surface are interference fit, and the interference amount is in the range of 0.1 mm to 1 mm.
[0020] It can be seen that the interference fit between the two can ensure that the driving seat has sufficient lifting force, so that the chip on the chip seat can be stably electrically connected to the electrical contact of the imaging device.
[0021] A preferred solution is that the extension direction of the second guide rail is perpendicular to the extension direction of the first guide rail.
[0022] A preferred solution is that the second force-bearing portion is arranged at an end of the driving seat away from the force-applying portion in the extension direction of the second guide rail.
[0023] It can be seen that the drive seat is ensured to cooperate with the internal structure of the printer and gradually extends out along with the installation action of the powder box.
[0024] 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.
[0025] A preferred solution is that a third guide portion is provided on the side wall of the chip seat opposite to the first guide portion; a fourth guide portion is provided on the side wall of the drive seat opposite to the second guide portion; a third guide rail and a fourth guide rail are provided on the end wall of the box body, the third guide rail is parallel to the first guide rail, the fourth guide rail is parallel to the second guide rail, the third guide portion is slidably matched with the third guide rail, and the fourth guide portion is slidably matched with the fourth guide rail.
[0026] It can be seen that by providing the guide parts on both sides of the driving seat and the chip seat, it is ensured that the driving seat and the chip seat are subjected to balanced forces, so that they can move stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION
[0041] Chip holder assembly and powder box first embodiment:
[0042] See also Figures 1 to 5 The powder box in this embodiment is a split box, the powder box includes a developing box and a drum frame, the developing box includes a box body 1 and a chip seat assembly 2, and the chip seat assembly 2 is arranged on the box body 1. The powder box in other embodiments can also be an integrated box, that is, the developing box is connected to the drum frame.
[0043] The chip seat assembly 2 includes a chip seat 3, a driving seat 4 and a housing 5, and the housing 5 is fixedly connected to the box body 1 by screws and other fixing parts. The chip seat 3 is provided with a first force-bearing portion 31, a chip mounting portion 32 and a first guide portion 33, and a chip 6 is provided at the chip mounting portion 32.
[0044] The drive seat 4 is provided with a second force-bearing portion 41, a force-applying portion 42 and a second guide portion 43, the shell 5 is provided with an installation cavity 50, the chip seat 3 and the drive seat 4 are both located in the installation cavity 50, the second force-bearing portion 41 is exposed from the shell 5, and the second force-bearing portion 41 is arranged at one end of the drive seat 4 away from the force-applying portion 42 in the extension direction of the second guide rail 52.
[0045] The side wall of the housing 5 is provided with a first guide rail 51 and a second guide rail 52. The first guide rail 51 extends along the normal direction of the electrical contact surface 61 on the chip 6, and the extension direction of the second guide rail 52 is perpendicular to the extension direction of the first guide rail 51. The first guide portion 33 is slidably matched with the first guide rail 51, and the second guide portion 43 is slidably matched with the second guide rail 52. In addition, a third guide portion 35 is provided on the side wall of the chip holder 3 opposite to the first guide portion 33, and a fourth guide portion (not shown) is provided on the side wall of the drive seat 4 opposite to the second guide portion 43. The end wall of the box body 1 is provided with a third guide rail 11 and a fourth guide rail 12. The third guide rail 11 is parallel to the first guide rail 51, and the fourth guide rail 12 is parallel to the second guide rail 52. The third guide portion 35 is slidably matched with the third guide rail 11, and the fourth guide portion is slidably matched with the fourth guide rail 12. By providing guide portions on both sides of the drive seat 4 and the chip holder 3, it is ensured that the drive seat 4 and the chip holder 3 are subjected to balanced forces, so that they can move stably.
[0046] A guide bevel 44 is provided at the top of the side of the drive seat 4 close to the second force-bearing part 41, and a guide mating surface 34 is provided at the bottom of the chip seat 3. The guide bevel 44 is inclined relative to the extension direction of the first guide rail 51, and the guide mating surface 34 is inclined relative to the extension direction of the second guide rail 52. The guide bevel 44 can slide with the guide mating surface 34.
[0047] The second force-bearing portion 41 drives the driving seat 4 to move along the extension direction of the first guide rail 51 after receiving the force. The force-applying portion 42 applies force to the first force-bearing portion 31 , and the first force-bearing portion 31 drives the chip holder 3 to move from the retracted position to the extended position along the second guide rail 52 .
[0048] In this embodiment, the first force receiving portion 31 includes a first magnet 311, and the force applying portion 42 includes a second magnet 421. The first magnet 311 and the second magnet 421 have the same magnetic pole on the opposite side. The chip seat 3 is provided with a first receiving groove 36, and the first magnet 311 is arranged in the first receiving groove 36. The drive seat 4 is provided with a second receiving groove 46, and the second magnet 421 is arranged in the second receiving groove 46. Figure 8 As shown, in the extended position, the first magnet 311 and the second magnet 421 are arranged opposite to each other in the extension direction of the first guide rail 51 .
[0049] See also Figures 3 to 8, when the user installs the powder box to the imaging device, the drive seat 4 is at the leftmost end of the second guide rail 52, and the chip seat 3 is at the lowest end of the first guide rail 51 under the action of its own gravity. At this time, the chip seat 3 and the chip 6 are in the retracted position. During the installation of the powder box, the chip seat 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 drive seat 4 contacts the abutment in the imaging device, and the drive seat 4 no longer moves with the powder box. At this time, when the user continues to push the powder box to the drop position, the second guide part 43 of the drive seat 4 slides to the right along the second guide rail 52, and the second magnet 421 in the drive seat 4 gradually approaches the first magnet 311 in the chip seat 3. Since the opposite ends of the first magnet 311 and the second magnet 421 have the same magnetic polarity, the two generate a repulsive force against each other. Due to the repulsive force generated by the magnets, the chip seat 3 rises along the first guide rail 51 and approaches the electrical contact parts of the imaging device. See. Figures 6 to 8 When the powder box is assembled in place, the first magnet 311 and the second magnet 421 are opposite to each other in the extension direction of the first guide rail 51, and the two magnets are completely opposite to each other. At this time, the repulsive force generated is large enough to keep the chip holder 3 in the extended position and allow the chip 6 to be close to the electrical contact part of the imaging device, thereby forming a stable electrical connection. The setting of the guide slope 44 on the drive seat 4 and the guide matching surface 34 on the chip seat 3 can enable the guide slope 44 to apply a thrust to the guide matching surface 34 when the second magnet 421 on the drive seat 4 is close to the first magnet 311 on the chip seat 3, ensuring that the chip seat 3 can move upward smoothly.
[0050] When the processing box is taken out from the imaging device, after the powder box drives the shell 5 and the chip holder 3 to move outward, the first magnet 311 and the second magnet 421 are misaligned in the extension direction of the first guide rail 51, and the repulsive force between the two is reduced. The repulsive force generated by the magnets is smaller than the gravity of the chip holder 3, etc. Therefore, the chip holder 3 gradually descends from the extended position to the retracted position along the first guide rail 51. At the same time, the drive seat 4 moves from the rightmost end of the second guide rail 52 to the leftmost position under the action of the repulsive force.
[0051] As can be seen from the above, through the cooperation between the chip seat and the drive seat, when the second force-bearing part of the drive seat is subjected to an external force, under the cooperation of the second guide part and the second guide rail, the drive seat moves relative to the housing along the extension direction of the second guide rail, and along with the movement of the drive seat relative to the housing, the force-applying part of the drive seat applies a force to the first force-bearing part of the chip seat, thereby driving the chip seat to move relative to the housing along the extension direction of the first guide rail to the extended position. Since in the initial state of the powder box installation, the chip and the chip seat are in the retracted position under the action of their own gravity, at this time, during the installation of the powder box, the chip seat will not interfere with other components 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 seat remain in the extended position, thereby achieving a stable electrical connection with the electrical contact parts of the imaging device. At the same time, in this embodiment, by arranging the first magnet of the chip holder opposite to the side with the same magnetic pole as the second magnet of the drive holder, when the drive holder moves relative to the housing so that the second magnet approaches the first magnet, the repulsive force between the two causes the chip holder to gradually move away from the drive holder along the extension direction of the first guide rail and approach the electrical contact component of the imaging device. When the powder box is assembled in place, the first magnet and the second magnet are arranged opposite to each other, and the repulsive force generated between the two is large enough to keep the chip and the chip holder in the extended position and close to the electrical contact component to form a stable electrical connection.
[0052] Chip holder assembly and powder box second embodiment:
[0053] 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.
[0054] See also Figures 9 to 13 The first force-bearing portion 7 includes a first sliding fitting surface 71 and a second sliding fitting surface 72 , and both the first sliding fitting surface 71 and the second sliding fitting surface 72 are inclined relative to the extension direction of the first guide rail 251 .
[0055] The force applying portion 8 includes a first sliding contact surface 81 and a second sliding contact surface 82. The angle θ1 between the first sliding contact surface 81 and the extension direction of the first guide rail 251 is greater than the angle θ2 between the second sliding contact surface 82 and the extension direction of the first guide rail 251. The first sliding mating surface 71 can be slidably mated with the first sliding contact surface 81, and the second sliding mating surface 72 can be slidably mated with the second sliding contact surface 82. As the second guide portion 243 slides along the second guide rail 252, as shown in FIG. Fig.11 As shown, the first sliding mating surface 71 contacts and slides relatively with the first sliding contact surface 81, and the chip holder 23 moves along the first guide rail 251 toward the extended position to the first position, as shown in FIG. Fig.12As shown, the second sliding contact surface 82 contacts and slides relatively with the second sliding matching surface 72 , and the first sliding matching surface 71 separates from the first sliding contact surface 81 until the chip holder 23 moves to the extended position.
[0056] The second sliding contact surface 82 and the second sliding matching surface 72 are interference-fitted, and the interference is in the range of 0.1 mm to 1 mm. The interference fit between the two can ensure that the drive seat 24 has sufficient lifting force, so that the chip 26 on the chip seat 23 can be stably electrically connected to the electrical contact of the imaging device.
[0057] It can be seen that by setting the sliding contact surface and the sliding matching surface for sliding fit, the driving seat can force the chip seat to be pushed out to the extended position during the installation process of the powder box. In addition, by setting two sliding contact surfaces with different inclination angles, it is ensured that the chip seat rises slowly in the initial stage to avoid interference with other components in the imaging device.
[0058] In addition, the extension direction of the second guide rail and the extension direction of the first guide rail may also be at an acute angle. In the above embodiments, the first guide portion, the second guide portion, the third guide portion and the fourth guide portion are all protrusions, and the first guide rail, the second guide rail, the third guide rail and the fourth guide rail are all grooves. In other embodiments, each guide portion may also be a groove, and each guide rail may be a protrusion accordingly. The above changes can also achieve the purpose of the utility model.
[0059] 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.
