Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to an upgrading device. Background Art

[0002] Printing equipment has become an indispensable device in people's daily life and work. Ink cartridges, toner cartridges, etc. are essential printing consumables for printing equipment. When the printing equipment is upgraded, in order to avoid the situation where the printing consumables do not recognize the machine, the printing consumables need to be upgraded accordingly. For example, after upgrading the serial number and other data of the printer, the serial number and other data of the printing consumables need to be upgraded as well, so as to avoid the situation where the printing consumables do not recognize the machine.

[0003] In the related art, the data connector of the upgrading device needs to be held by the operator to dock with the chip of the printing consumables. At this time, the data connector and the chip are electrically connected after docking, and then the upgrading operation of the printing consumables can be performed. During the upgrading process of the printing consumables, the operator is also required to hold the data connector all the time to ensure that the data connector and the chip are always docked.

[0004] However, during long-term operation, operators are prone to hand shaking, which can easily cause the data connector to vibrate or shake to a large extent, thereby causing the electrical connection between the data connector and the chip to be disconnected, which can easily lead to the risk of failure in upgrading the printing consumables. Therefore, the reliability of the upgrading equipment in the related art is poor. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 6 As shown, the embodiment of the utility model discloses an upgrade device 100, which is used to perform data upgrade on printing consumables 200 such as ink cartridges and toner cartridges. The disclosed upgrade device 100 includes a device body 110, an electrical connection part 120 and a clamping part 130.

[0021] The device body 110 includes but is not limited to the device housing, circuit board, power supply, and electronic components. The electrical connection part 120 is provided on the device body 110, and the electrical connection part 120 here is used to electrically connect with the chip 210 of the printing consumables 200. Specifically, the electrical connection part 120 is fixedly mounted on the device body 110, and the electrical connection part 120 is electrically connected with the circuit structure of the device body 110. Optionally, the electrical connection part 120 can be a structure such as a gold finger, a metal spring, a metal pin, a metal contact pin, etc. Of course, the electrical connection part 120 can also be other structures. For example, the electrical connection part 120 may include a bracket and a metal conductor, the bracket is used to support the metal conductor, the bracket is fixedly connected to the device body, and the metal conductor can be used to contact and electrically connect with the chip of the printing consumables 200. This article only discloses several specific structures of the electrical connection part 120, and is not used to limit the specific structure of the electrical connection part 120.

[0022] The clamping portion 130 is disposed on the device body 110 , and the clamping portion 130 includes at least two elastic clamping members disposed opposite to each other. A clamping space 1301 can be formed between the at least two elastic clamping members disposed opposite to each other, and the clamping space 1301 is used to clamp the printing consumables 200 .

[0023] In the specific upgrade process, the operator applies a force to at least one elastic clamping member, at which time, at least one elastic clamping member is compressed, thereby increasing the size of the clamping space 1301 until the printing consumable 200 can be placed in the clamping space 1301. At this time, the operator places the printing consumable 200 in the clamping space 1301, and the chip 210 of the printing consumable 200 is docked with the electrical connection part 120, thereby achieving electrical connection. Then, the force applied to the elastic clamping member is removed, and the elastic clamping member restores elastic deformation, and at least two relatively arranged elastic clamping members abut against the opposite sides of the printing consumable 200, thereby limiting the outer dimensions of the printing consumable 200, and then the clamping part 130 clamps the printing consumable 200. When the upgrade device 100 completes the clamping operation of the printing consumable 200, the device body 110 realizes data conduction with the printing consumable 200 through the electrical connection part 120, and the upgrade device 100 can perform an upgrade operation on the printing consumable 200.

[0024] When the at least two relatively disposed elastic clamping members in this solution clamp the printing consumable 200, the forces exerted on the printing consumable 200 are equal in magnitude and opposite in direction, thereby enabling the printing consumable 200 to remain in the clamped position.

[0025] For example, in the present application, at least two relatively arranged elastic clamps can be arranged along the length direction of the printing consumable 200, in which case at least two relatively arranged elastic clamps can limit the length direction of the printing consumable 200; or, at least two relatively arranged elastic clamps can be arranged along the width direction of the printing consumable 200, in which case at least two relatively arranged elastic clamps can limit the width direction of the printing consumable 200; or, at least two relatively arranged elastic clamps can be arranged along the height direction of the printing consumable 200, in which case at least two relatively arranged elastic clamps can limit the height direction of the printing consumable 200. Of course, the upgrade device 100 disclosed in the present application can also limit the size in other ways, which is not limited herein.

[0026] In the embodiment disclosed in the present application, after the printing consumable 200 is clamped by the clamping portion 130, the clamping portion 130 limits the position of the printing consumable 200, so that the printing consumable 200 does not move relative to the electrical connection portion 120, thereby ensuring that the chip 210 of the printing consumable 200 is not likely to be disconnected from the electrical connection portion 120, thereby improving the reliability of the upgrade device 100. Compared with the upgrade device 100 in the related art, the upgrade device 100 disclosed in the present application limits the position of the printing consumable 200 by the clamping portion 130, so there is no need for the operator to hold the device all the time, so it is not easy to cause a large vibration or jitter between the chip 210 of the printing consumable 200 and the electrical connection portion 120, thereby avoiding the risk of failure in upgrading the printing consumable 200, so the upgrade device 100 disclosed in the present application has higher reliability.

[0027] In addition, in the upgrade device 100 disclosed in the present application, the printing consumables 200 can be clamped and removed by applying force to the elastic clamping member, thereby making the operation of the upgrade device 100 simpler and more convenient.

[0028] In addition, the clamping portion 130 of the upgrade device 100 disclosed in the present application elastically limits the printing consumables 200, so that the limiting size of the clamping space 1301 of the clamping portion 130 is adjustable, thereby making the upgrade device 100 disclosed in the present application compatible with printing consumables 200 of different sizes.

[0029] Optionally, the elastic clamping member may be a spring, one end of which is connected to the device body 110, and the other end of which is a free end. When the printing consumable 200 is clamped in the clamping space 1301, the free end of the spring abuts against the printing consumable 200. Of course, the elastic clamping member may also be a spring sheet or other structure, and the specific structure of the elastic clamping member is not limited herein.

[0030] In order to further improve the reliability of the upgrading device 100 , in another optional solution, the upgrading device 100 may further include a positioning portion 140 , and the positioning portion 140 may be used to position and cooperate with the printing consumables 200 .

[0031] In the specific operation process, the operator increases the size of the clamping space 1301 until the printing consumable 200 can be placed in the clamping space 1301. At this time, the operator places the printing consumable 200 in the clamping space 1301 and connects the printing consumable 200 with the positioning portion 140. The positioning portion 140 can position the size of the printing consumable 200 in the clamping space 1301, so that the chip 210 of the printing consumable 200 can be accurately connected with the electrical connection portion 120.

[0032] In this solution, the positioning portion 140 can position the printing consumables 200 in the clamping space 1301, thereby improving the matching accuracy between the chip 210 of the printing consumables 200 and the electrical connection portion 120, thereby avoiding the risk of offset between the chip 210 of the printing consumables 200 and the electrical connection portion 120, and further improving the reliability of the upgrade device 100.

[0033] Optionally, the positioning portion 140 may be a positioning groove, and the printing consumable 200 may be provided with a matching protrusion, and at least a portion of the matching protrusion may extend into the positioning groove, so as to achieve the positioning and matching of the printing consumable 200 and the device body 110. Alternatively, the positioning portion 140 may be a positioning protrusion, and the printing consumable 200 may be provided with a matching groove, and at least a portion of the positioning protrusion may extend into the matching groove to achieve the positioning and matching.

[0034] In an optional solution, the positioning portion 140 may be a positioning protrusion, and the positioning protrusion may be a columnar, conical, or other structure. The positioning protrusion may be positioned and matched with an existing hole on the shell of the printing consumable 200. For example, the printing consumable 200 is provided with an air inlet, and the air inlet on the printing consumable 200 is used to inflate air into the printing consumable 200. The positioning protrusion may be positioned and matched with the air inlet on the printing consumable 200. This solution utilizes the original holes on the printing consumable 200 for positioning, so that there is no need to change the original appearance structure of the printing consumable 200, thereby making the upgrade of the printing consumable 200 simpler and more cost-effective.

[0035] In order to further improve the clamping stability of the clamping portion 130, in another optional embodiment, at least two relatively arranged elastic clamping members may be respectively a first elastic clamping member and a second elastic clamping member, the first elastic clamping member may include a first elastic portion 131 and a first clamping plate 133, and the second elastic clamping member may include a second elastic portion 132 and a second clamping plate 134. The first clamping plate 133 may be arranged opposite to the second clamping plate 134, and a clamping space 1301 is formed between the first clamping plate 133 and the second clamping plate 134. The first elastic portion 131 is located on a side of the first clamping plate 133 away from the second clamping plate 134, and the device body 110 and the first clamping plate 133 may be elastically connected through the first elastic portion 131. The second elastic portion 132 may be located on a side of the second clamping plate 134 away from the first clamping plate 133, and the device body 110 and the second clamping plate 134 may be elastically connected through the second elastic portion 132.

[0036] In the specific operation process, the operator applies a force to at least one of the first clamping plate 133 and the second clamping plate 134, and at least one of the first elastic part 131 and the second elastic part 132 is compressed, so that the distance between the first clamping plate 133 and the second clamping plate 134 increases, and the distance between the first clamping plate 133 and the second clamping plate 134 is the clamping size of the clamping space 1301. When the first clamping plate 133 and the second clamping plate 134 move to a position where they do not interfere with the printing consumables 200, the printing consumables 200 are placed between the first clamping plate 133 and the second clamping plate 134, and then the force applied to the first clamping plate 133 and the second clamping plate 134 is removed, and the first elastic part 131 and the second elastic part 132 recover their deformation, so that the first clamping plate 133 and the second clamping plate 134 are close to each other, until the first clamping plate 133 and the second clamping plate 134 are against the two sides of the printing consumables 200.

[0037] In this solution, the contact area between the first clamp 133 and the second clamp 134 and the printing consumables 200 is relatively large, so that the force positions on both sides of the printing consumables 200 are close, making it less likely for the printing consumables 200 to slide and deviate due to uneven force, thereby further improving the clamping stability of the clamping portion 130.

[0038] Further, the first elastic portion 131 may include a first spring 1311 and a second spring 1312, and the first spring 1311 and the second spring 1312 may be arranged at intervals along the length direction of the first clamping plate 133. In this solution, the first spring 1311 and the second spring 1312 can ensure that the force on the first clamping plate 133 along the length direction is more uniform, thereby further avoiding the risk of disconnection between the printing consumables 200 and the electrical connection portion 120 due to uneven force on the front and rear ends of the printing consumables 200, thereby further improving the safety and reliability of the upgrade device 100.

[0039] Similarly, the second elastic portion 132 may include a third spring 1321 and a fourth spring 1322, and the third spring 1321 and the fourth spring 1322 may be arranged at intervals along the length direction of the second clamping plate 134. In this solution, the third spring 1321 and the fourth spring 1322 can ensure that the force on the second clamping plate 134 along the length direction is more uniform, thereby further avoiding the risk of disconnection between the printing consumables 200 and the electrical connection portion 120 due to uneven force on the front and rear ends of the printing consumables 200, thereby further improving the safety and reliability of the upgrade device 100.

[0040] In the above embodiment, the first clamping plate 133 and the second clamping plate 134 are prone to the risk of interfering with the electrical connection part 120. Based on this, in another optional embodiment, the first clamping plate 133 may be provided with a first avoidance notch 1331, and the second clamping plate 134 may be provided with a second avoidance notch 1341. The first avoidance notch 1331 and the second avoidance notch 1341 may both be arranged opposite to the electrical connection part 120. In this solution, during the movement of the first clamping plate 133 and the second clamping plate 134, the first clamping plate 133 may avoid the electrical connection part 120 through the first avoidance notch 1331, and the second clamping plate 134 may avoid the electrical connection part 120 through the second avoidance notch 1341, thereby avoiding the risk of the first clamping plate 133 and the second clamping plate 134 interfering with the electrical connection part 120.

[0041] In another optional solution, the device body 110 may be provided with a receiving groove 1101, and the clamping portion 130, the positioning portion 140 and the electrical connection portion 120 may all be located in the receiving groove 1101. In this case, the clamping portion 130 defines a portion of space in the receiving groove 1101 as the clamping space 1301. In other words, the printing consumables 200 are clamped in the receiving groove 1101. In this solution, the printing consumables 200 are clamped in the receiving groove 1101, so the exposed volume of the printing consumables 200 is small, so that the printing consumables 200 are not prone to the risk of accidental contact, thereby further improving the reliability of the upgraded device 100.

[0042] In the above embodiment, a receiving groove 1101 may be formed on the device body 110 , and the receiving groove 1101 may be a groove structure. For example, the receiving groove 1101 has a bottom wall and a circumferential side wall arranged around the bottom wall.

[0043] In another optional embodiment, the device body 110 may include a main body 111, a first extension plate 112, a second extension plate 113 and a bottom plate 114, the first extension plate 112 and the second extension plate 113 may be located at both ends of the main body 111, and the first extension plate 112 and the second extension plate 113 are arranged opposite to each other, and the bottom plate 114 may be located between the first extension plate 112 and the second extension plate 113. The main body 111, the first extension plate 112, the second extension plate 113 and the bottom plate 114 together form a receiving groove 1101, and the bottom plate 114 is the groove bottom of the receiving groove 1101. At this time, the receiving groove 1101 penetrates the device body 110 toward the side away from the main body 111. That is, the receiving groove 1101 has three side walls, which are the side walls corresponding to the main body 111, the first extension plate 112 and the second extension plate 113, respectively, and there is no side wall on the opposite side of the main body 111, so the receiving groove 1101 is a notch structure.

[0044] In this solution, one side of the receiving slot 1101 passes through the device body 110, so when the printing consumables 200 are long, the printing consumables 200 can extend from the passing side to the outside of the receiving slot 1101, so the receiving slot 1101 of this structure can accommodate more medium-sized printing consumables 200. At the same time, the receiving slot 1101 of this structure will not affect the assembly of the components of the upgrade device 100.

[0045] In the above embodiment, the main body 111 may be provided with a device installation space, and components such as a circuit board, a power supply, and electronic components in the upgrade device 100 may be assembled in the device installation space.

[0046] In an optional solution, one end of the first elastic portion 131 may be connected to the first extension plate 112, and the other end of the first elastic portion 131 may be connected to the first clamping plate 133. One end of the second elastic portion 132 may be connected to the second extension plate 113, and the other end of the second elastic portion 132 may be connected to the second clamping plate 134. The electrical connection portion 120 may be disposed on the main body 111.

[0047] In this solution, the first extension plate 112 is arranged opposite to the first clamping plate 133, and the second extension plate 113 is arranged opposite to the second clamping plate 134. Therefore, the length direction of the first clamping plate 133 and the second clamping plate 134 is the same as the extension direction of the first extension plate 112 and the second extension plate 113. At this time, the operator can install and disassemble the printing consumables 200 along the extension direction of the first extension plate 112 and the second extension plate 113, thereby avoiding the risk of interference between the printing consumables 200 and the first extension plate 112 and the second extension plate 113. The upgrade device 100 of this structure has a regular and simple structure and better appearance performance.

[0048] In the above embodiment, if the volume of the protruding bottom plate 114 of the printing device is relatively large, causing the center of gravity of the printing consumables 200 to be positioned backward, it is easy to cause the printing consumables 200 to tilt backward, which in turn may easily lead to the risk of a poor connection between the chip 210 of the printing consumables 200 and the electrical connector, and may even easily cause the printing consumables 200 to fall off the upgrade device 100.

[0049] Based on this, in another optional solution, the bottom plate 114 may have a first side 114a and a second side 114b that are arranged opposite to each other, and the first side 114a may be located on a side of the bottom plate 114 close to the main body 111, and the first side 114a here may be against the main body 111. The second side 114b may be located on a side of the bottom plate 114 away from the main body 111. The dimension between the first side 114a and the second side 114b may be a first dimension. In the direction from the first side 114a to the second side 114b, the dimension of the printing consumables 200 is a second dimension, and the first dimension may be greater than or equal to half of the second dimension. The direction from the first side 114a to the second side 114b here may also be understood as the extension direction of the first extension plate 112 or the second extension plate 113.

[0050] In this solution, the length dimension of the supporting surface of the bottom plate 114 for the printing consumables 200 is at least half of the length of the printing consumables 200, so that the center of gravity of the printing consumables 200 falls on the bottom plate 114 as much as possible, thereby avoiding the risk of the printing consumables 200 tipping backward, and further improving the reliability of the upgrade device 100.

[0051] In another optional embodiment, the bottom plate 114 can be detachably connected to the first extension plate 112 and the second extension plate 113. In this solution, the bottom plate 114 is detachable from the first extension plate 112 and the second extension plate 113, so the operator can replace the bottom plate 114 of different sizes according to the length of the printing consumables 200, so that the length of the printing consumables 200 can be adapted to the size of the bottom plate 114, thereby further improving the compatibility of the upgrade device 100.

[0052] In the above embodiment, the bottom plate 114 can be connected to the first extension plate 112 and the second extension plate 113 by bolt threads. However, multiple bolts need to be screwed when the bottom plate 114 is disassembled and installed, which makes the disassembly and installation of the bottom plate 114 difficult.

[0053] Based on this, in another optional solution, a first slide groove 1121 may be provided on one side edge of the first extension plate 112, and the extension direction of the first slide groove 1121 is parallel to the extension direction of the first extension plate 112. A second slide groove 1131 may be provided on one side edge of the second extension plate 113, and the extension direction of the second slide groove 1131 is parallel to the extension direction of the second extension plate 113. The bottom plate 114 may be slidably matched with both the first slide groove 1121 and the second slide groove 1131.

[0054] In this solution, when the bottom plate 114 is connected to the first extension plate 112 and the second extension plate 113, the operator aligns the two side edges of the bottom plate 114 with the first slide groove 1121 and the second slide groove 1131 respectively, and then slides the bottom plate 114 to a specified position, which can be understood here as the bottom plate 114 sliding into a position abutting against the main body 111, thereby achieving the installation operation of the bottom plate 114. When the bottom plate 114 is separated from the first extension plate 112 and the second extension plate 113, the operator slides the bottom plate 114 in the opposite direction to the sliding direction of the bottom plate 114 until the bottom plate 114 slides out of the first slide groove 1121 and the second slide groove 1131, thereby separating the bottom plate 114 from the first extension plate 112 and the second extension plate 113, thereby achieving the disassembly operation of the bottom plate 114.

[0055] In this solution, the bottom plate 114 can be installed and removed by sliding the bottom plate 114 in different directions. Therefore, the installation and removal operations of the bottom plate 114 are simpler and more directional, making the removal and installation of the bottom plate 114 less difficult.

[0056] In another solution, the bottom plate 114 and the first extension plate 112 and the second extension plate 113 can be connected in the direction of magnetic attraction, that is, the bottom plate 114, the first extension plate 112 and the second extension plate 113 can be provided with magnetic parts, so as to realize the magnetic attraction connection between the bottom plate 114 and the first extension plate 112 and the second extension plate 113. Of course, the bottom plate 114 and the first extension plate 112 and the second extension plate 113 can also adopt other detachable connection methods, which are not limited in this article.

[0057] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0058] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
