Description

Technical Field

[0001] This invention relates to the field of chip mounting structure technology, and more particularly to a mounting structure for a toner cartridge chip. Background Technology

[0002] In the manufacturing of existing laser printer toner cartridges, the chip mounting structure generally adopts a static fixing scheme, that is, embedding it into a slot on the end face of the toner cartridge shell, and keeping the chip surface flush with or slightly concave with the end face of the shell. This conventional design, however, has led to a core technical contradiction that is interconnected and mutually causal: in order to ensure a reliable connection between the chip contacts and the printer probes, its surface must be as close as possible to the end face of the shell, but this results in its long-term direct exposure to the external environment.

[0003] During transportation, handling, and storage, the chip surface of the flush-mount design lacks physical barriers, making its delicate contacts and packaging structure extremely vulnerable to permanent damage from direct impacts and scratches. This static compromise in structure cannot fundamentally reconcile the conflict between the "unobstructed contact" required for the chip in its working state and the "all-around protection" required for its non-working state. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing a dynamic protection structure that can actively change the microenvironment of the chip in the toner cartridge according to the working state of the toner cartridge.

[0005] The technical solution of the present invention: a mounting structure for a toner cartridge chip, including a toner cartridge shell, and further comprising: A chip mounting module is installed on the end face of the toner cartridge casing. The chip mounting module includes a chip support and a protective mechanism. A chip is mounted on the chip support. The end face of the toner cartridge casing has a connection window for the chip to pass through. The protective mechanism includes a sealing plate for sealing the connection window and a transmission component for controlling the flatness of the concavity between the chip and the end face of the toner cartridge casing based on the height of the sealing plate. The transmission component includes a guide rod connected to the chip support. The guide rod has a first inclined portion and a drive wheel slidably mounted on the guide rod. The drive wheel is rotatably connected to the sealing plate. Optionally, the chip support includes a slide rail disposed inside the toner cartridge housing and a slide plate slidably mounted inside the slide rail. The slide plate is provided with a snap-fit ​​groove, and a snap-fit ​​plate is slidably mounted in the snap-fit ​​groove. The snap-fit ​​plate is provided with a positioning groove, and the chip is snapped into the positioning groove.

[0006] Optionally, the card plate is provided with a disassembly hole, and an elastic strip is fixedly installed around the positioning groove inside the card plate. The card plate is provided with chamfers.

[0007] Optionally, the toner cartridge housing is provided with a receiving groove for accommodating a sealing plate. Sliding grooves are provided on both sides of the receiving groove. The sealing plate is slidably installed inside the receiving groove. A toggle block is fixedly installed on the sealing plate. The toggle block is located inside the sliding groove on one side. A transmission rod is fixedly installed on the other side of the sealing plate. The transmission rod is located inside the sliding groove on the other side. The drive wheel is rotatably connected to the transmission rod.

[0008] Optionally, a sealing sheet is fixedly installed between one end of the sealing plate and one end of the receiving groove, and the sealing sheet is a foldable rubber sheet.

[0009] Optionally, a rubber pad is fixedly installed on one side of the skateboard, and a support frame is fixedly installed on the rubber pad. The support frame is fixedly connected to the guide rod.

[0010] Optionally, the guide rod further includes a first translation part disposed on one side of the first inclined part, a second inclined part disposed on one side of the first translation part, a second translation part disposed at one end of the second inclined part, and a third translation part disposed at the other end of the first inclined part.

[0011] Optionally, a junction point is provided on the upper side of the first inclined portion, and the sealing plate begins to enter or leave the connecting window when the drive wheel is located at the junction point.

[0012] Optionally, the first translation section is provided with a resistance positioning point, which includes an elastic pad fixedly installed inside the first translation section and a conical protrusion fixedly installed on the elastic pad.

[0013] Optionally, a support rod is fixedly installed inside the toner cartridge shell, and the guide rod is slidably connected to the support rod. In summary, this application includes at least one of the following beneficial technical effects: This application successfully resolves the fundamental contradiction between protection and connectivity in traditional designs by linking the sealing plate with the chip. It achieves "hidden protection" of the chip during storage and transportation and "precise exposure" during operation. Through the cooperation of the sliding plate, the card plate and the elastic strip, the installation and replacement of the chip becomes extremely simple and safe, significantly improving maintainability.

Detailed Implementation

[0016] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0018] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the description of this application, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figures 1 to 6 As shown, the present invention proposes an installation structure for a toner cartridge chip, including a toner cartridge shell 1 and a chip installation module 2 installed on the end face of the toner cartridge shell 1. The chip installation module 2 includes a chip support 21 and a protective mechanism 22. A chip 215 is installed on the chip support 21. The chip 215 is the core intelligent management unit of the toner cartridge. The chip 215 stores key identity and status information such as the model, serial number, and toner capacity of the toner cartridge. Its core function is to establish bidirectional communication with the printer. When the toner cartridge is installed in the printer, the exposed metal contacts on the chip 215 will make precise contact with the corresponding elastic spring probe array inside the printer and form an electrical connection.

[0022] Furthermore, the end face of the drum housing 1 is provided with a connection window 23 for the chip 215 to pass through. The chip 215 can be parallel to the end face of the drum housing 1 through this connection window, allowing it to contact the spring probe at the printer's temporal position. The protective mechanism 22 includes a sealing plate 221 that seals the connection window 23 and a transmission component that controls the flatness of the concave area between the chip 215 and the end face of the drum housing 1 based on the height of the sealing plate 221. By sealing the connection window 23 with the sealing plate 221, the chip 215 is protected, preventing wear during transportation. Specifically, the transmission component can control the chip 215 to be concave into the drum housing 1. The device can also control the end face of the chip 215 to be parallel to the end face of the drum housing 1. If the chip 215 is recessed inside the drum housing 1 to ensure the installation of the sealing plate 221, the chip 215 will not be able to form an effective electrical connection with the printer probe. Moreover, when installing the drum, the probe needs to enter the drum housing 1 to connect with the chip 215, which will inevitably cause friction between the drum housing and the drum housing 1 during installation, which may easily damage the probe inside the printer. The protective mechanism 22 can avoid this problem and satisfy the installation of the sealing plate 221 and the flushness between the chip 215 and the end face of the drum housing 1.

[0023] Furthermore, the transmission assembly includes a guide rod 224 connected to the chip support base 21, a support rod 25 fixedly installed inside the drum housing 1, and the guide rod 224 slidably connected to the support rod 25, allowing the guide rod 224 to slide inside the drum housing 1. The guide rod 224 is provided with a first inclined portion 2241, and a drive wheel 227 is slidably installed on the guide rod 224. The drive wheel 227 is rotatably connected to the sealing plate 221, thereby allowing the drive wheel 227 to rise and fall with the lifting and lowering of the sealing plate 221. Under the action of the first inclined portion 2241, the rising and lowering drive wheel 227 can cause the guide rod 224 to move towards or away from the end face of the drum housing 1, thereby driving the chip 215 to move.

[0024] like Figures 1 to 3 and Figure 8As shown, in this embodiment, the chip support base 21 includes a slide 218 disposed inside the drum housing 1 and a slide plate 211 slidably installed inside the slide 218. The slide plate 211 is provided with a snap-fit ​​groove 212, and a snap-fit ​​plate 213 is slidably installed in the snap-fit ​​groove 212. The snap-fit ​​plate 213 is provided with a positioning groove 214. The chip 215 is snapped into the positioning groove 214. When installing the chip 215, firstly, the snap-fit ​​plate 213 is pulled out from inside the snap-fit ​​groove 212, and the chip 215 is pressed and snapped into the positioning groove 214. Then, the snap-fit ​​plate 213 is inserted into the slide plate 211 to complete the installation. At this time, pushing the slide plate 211 to move inside the slide 218 can control the distance between the end face of the chip 215 and the end face of the drum housing 1.

[0025] Furthermore, the card plate 213 is provided with a disassembly hole 216, and elastic strips 2141 are fixedly installed around the positioning groove 214 inside the card plate 213. The card plate 213 is provided with a chamfer 217, and the chip 215 is provided with a notch corresponding to the chamfer 217, which can ensure the accuracy of the chip 215 installation position. The elastic strips 2141 can apply a fastening force to the chip 215, so that the chip is fastened inside the positioning groove 214. When the chip 215 is disassembled and replaced, a pushing force can be applied to the back of the chip 215 through the disassembly hole 216 to facilitate the removal of the chip 215.

[0026] like Figures 1 to 7 As shown, in this embodiment, the drum shell 1 is provided with a receiving groove 231 for accommodating the sealing plate 221. Sliding grooves 232 are provided on both sides of the receiving groove 231. The sealing plate 221 is slidably installed inside the receiving groove 231. A toggle block 2211 is fixedly installed on the sealing plate 221. The toggle block 2211 is located inside the sliding groove 232 on one side. The toggle block 2211 facilitates the movement of the sealing plate 221. A transmission rod 222 is fixedly installed on the other side of the sealing plate 221. The transmission rod 222 is located inside the sliding groove 232 on the other side. The drive wheel 227 is rotatably connected to the transmission rod 222, so that the drive wheel 227 can move synchronously with the sealing plate 221.

[0027] Furthermore, the guide rod 224 also includes a first translation part 2242 disposed on one side of the first inclined part 2241, a second inclined part 2243 disposed on one side of the first translation part 2242, one end of the second inclined part 2243 disposed on the second translation part 2244, and a third translation part 2245 disposed on the other end of the first inclined part 2241. When the drive wheel 227 is above the first inclined part 2241 and in an upward state, it will drive the guide rod 224 to move towards the end face of the drum housing 1. This causes the chip 215 to move to a position coplanar with the end face of the drum housing 1. Conversely, when the sealing plate 221 is moved down to seal the connecting window 23, the chip 215 can move into the drum housing 1. At this time, the chip 215 will make way for the sealing plate 221 to prevent motion interference. When the drive wheel 227 is located at the positions of the first translation part 2242, the second translation part 2244, and the third translation part 2245, the movement of the drive wheel 227 will not drive the guide rod 224 to move.

[0028] When the sealing plate 221 seals the connecting window 23, the control chip 215 needs to be recessed into the toner cartridge housing 1 before the sealing plate 221 enters the connecting window. After the sealing plate 221 bends away from the connecting window 23, the sealing plate 221 needs to continue to move upward so that the chip 215 enters the connecting window 23, so that the chip 215 and the end face of the toner cartridge housing 1 are coplanar. It should be noted that the upper side of the first inclined part 2241 is provided with a junction point 2246. When the drive wheel 227 is located at the junction point 2246, the sealing plate 221 begins to enter or leave the connecting window 23. The above requirements can be met by setting the junction point 2246.

[0029] Furthermore, the first translation section 2242 is provided with a resistance positioning point, which includes an elastic soft pad 225 fixedly installed inside the first translation section 2242 and a conical protrusion 226 fixedly installed on the elastic soft pad 225. When the chip 215 is removed, the card plate 213 needs to protrude from the surface of the drum shell 1 to facilitate the removal of the card plate 213. At this time, the sealing plate 221 needs to be pushed to allow the sealing plate 221 to pass through the first translation section 2242 and enter the second inclined section 2243, so that the card plate 213 can protrude from the drum shell 1. When the drive wheel 227 passes through the conical protrusion 226, the conical protrusion needs to be pressed into the elastic soft pad 225 to apply resistance to the drive wheel 227. This can serve as a reminder and prevent the card plate 213 from protruding from the drum shell 1 when the chip 215 does not need to be installed or removed.

[0030] A sealing plate 24 is fixedly installed between one end of the sealing plate 221 and one end of the receiving groove 231. The sealing plate 24 is a foldable rubber sheet. The sealing plate 24 seals the receiving groove 231 to prevent external impurities from entering the interior of the drum shell 1 through the sliding groove 232 and the receiving groove 231.

[0031] like Figure 8 As shown, in this embodiment, a rubber pad 219 is fixedly installed on one side of the slide plate 211, and a support frame 223 is fixedly installed on the rubber pad 219. The support frame 223 is fixedly connected to the guide rod 224. By setting the rubber pad 219, the chip 215 can move in a small position within a certain range, which can ensure that the chip 215 does not get stuck during the installation process, and keep the chip 215 in stable contact with the spring probe inside the printer.

[0032] In this embodiment, in the non-operating state, an external force pushes the actuating block 2211, causing the sealing plate 221 to move downwards and eventually embed into the connecting window 23, achieving a physical seal to the outside. During this process, the drive wheel 227 fixed on the sealing plate 221 moves downwards along the first inclined portion 2241 of the guide rod 224. The inclined surface forces the guide rod 224 to drive the entire chip support 21 to retract into the drum, causing the chip 215 end face to concave and be fully protected. When operation is required, the actuating block 2211 is pushed in the opposite direction, causing the sealing plate 221 to move upwards and exit the connecting window 23. The drive wheel 227 moves upward along the first inclined portion 2241, and the guide rod 224 drives the chip support 21 and the chip 215 to move towards the end face of the drum under the action of the inclined surface until the end face of the chip 215 is flush with the end face of the drum shell 1, thereby establishing a stable electrical connection with the printer probe. The first translation portion 2242, the second translation portion 2244 and the third translation portion 2245 provided on the guide rod 224 ensure that the sealing plate 221 and the chip 215 do not interfere with each other in the critical stroke section, while the elastic soft pad 225 and the conical protrusion 226 provide tactile feedback for operation and prevent misoperation.

[0033] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
