Chip holder and toner cartridge

Abstract

The present invention discloses a chip bracket, comprising: a bottom plate, used to connect the shell of a toner cartridge; a support frame, detachably arranged on the bottom plate; a mounting plate, movably arranged on the support frame, and provided with a card slot; an elastic component, connected to the bottom of the mounting plate, and used to drive the mounting plate to reset. When the chip bracket is installed in an imaging device, the electrical contact point in the imaging device contacts the chip on the mounting plate, and performs extrusion interference on the chip. The chip and the mounting plate move along the support frame toward the bottom plate on the support frame, which can avoid the rigid contact between the electrical contact point and the electrical contact surface of the chip, resulting in friction and damage to the electrical contact surface. The buffering process is completed by the elastic component. After the interference disappears, the mounting plate is reset by the elastic potential energy of the elastic component. The structure is simple, and the electrical contact surface of the chip can be effectively prevented from being scratched. The electrical contact surface of the chip can also be prevented from being scratched during the disassembly process, so that the chip can be reused.

[0040] Reference Figures 1 to 5 According to the technical solution of the first aspect of the present invention, a chip holder comprises: a bottom plate 100, used to connect the shell of the toner cartridge; a support frame 200, detachably arranged on the bottom plate 100; a mounting plate 300, movably arranged on the support frame 200, and provided with a card slot 310 on the mounting plate 300; an elastic component 400, connected to the bottom of the mounting plate 300, and the elastic component 400 is used to drive the mounting plate 300 to reset. It can be understood that during the installation process, the chip is assembled on the card slot 310 of the mounting plate 300. When the chip contacts the electrical contacts in the imaging device, the electrical contacts squeeze the chip. Since the mounting plate 300 is movably arranged on the support frame 200, the chip is connected to the mounting plate 300 and moves along the support frame 200 toward the bottom plate 100, that is, Figures 1 to 5 The mounting plate 300 moves downward, and at the same time, the mounting plate 300 squeezes the elastic component 400. The elastic component 400 acts as a buffer for the mounting plate 300 and accumulates elastic potential energy. After being installed in place, the elastic component 400 drives the mounting plate 300 and the chip to rebound and reset, and allows the chip to be close to the electrical contacts to ensure good contact between the chip and the electrical contacts. The disassembly process is similar to the above process. After the disassembly is completed, the elastic component 400 drives the mounting plate 300 and the chip to reset. At this time, the chip can be removed from the mounting plate 300 for secondary use.

[0041] The application of the above-mentioned chip holder has at least the following beneficial effects: when the chip holder is installed in the imaging device, the electrical contact points in the imaging device contact the chip on the mounting plate 300 and squeeze the chip. The chip and the mounting plate 300 move on the support frame 200 along the support frame 200 toward the base plate 100, which can avoid rigid contact between the electrical contact points and the electrical contact surface of the chip, resulting in friction that damages the electrical contact surface. The elastic component 400 completes the buffering process. After the interference disappears, the elastic potential energy of the elastic component 400 resets the mounting plate 300. The structure is simple and can effectively prevent the electrical contact surface of the chip from being scratched. The electrical contact surface of the chip can also be prevented from being scratched during disassembly, so that the chip can be reused.

[0042] According to some embodiments of the present invention, the elastic component 400 includes a guide rod 410, a spring 420 and a baffle 430. The guide rod 410 is connected to the bottom of the mounting plate 300, and the baffle 430 is arranged on the bottom plate 100. The bottom plate 100 is provided with a clearance hole for allowing the guide rod 410 to pass through. The spring 420 is arranged on the rod body of the guide rod 410, and the two ends are respectively abutted against the mounting plate 300 and the baffle 430. During the assembly process, the guide rod 410 plays a directional role in the movement of the mounting plate 300, ensuring the accuracy of the moving direction of the mounting plate 300, and ensuring that the chip always maintains the correct installation angle. The spring 420 can play a buffering and resetting role for the mounting plate 300, such as Figure 1 and Figure 2 As shown, in this embodiment, the support frame 200 is detachably connected to the bottom plate 100, and an elastic card plate 500 is provided on the outer side of the support frame 200. The shape of the elastic card plate 500 is as shown in FIG. Figure 2 As shown, one end is open and is made of elastic material. The first edge of the elastic card plate 500 is fitted and connected to the support frame 200, and the second edge is tilted outward, and a compression spring is arranged between the two sides. A first undercut 510 is arranged at the lower end of the second edge. The first undercut 510 can be stuck in the edge of the mounting hole 110, and the elastic card plate 500 is stuck in the mounting hole 110, so that the support frame 200 is connected to the base plate 100. When the support frame 200 needs to be removed, the second edge of the elastic card plate 500 on both sides of the support frame 200 is pressed at the same time. The deformation of the second edge makes the first undercut 510 disengage from the edge of the mounting hole 110, so that the support frame 200 is removed from the base plate 100, and the support frame 200 and the chip can be replaced very conveniently, which is convenient for secondary disassembly and assembly. At the same time, the compression spring between the first edge and the second edge makes the second edge always maintain a tendency to move outward, so as to ensure that the first undercut 510 is firmly stuck in the edge of the mounting hole 110.

[0043] In addition to the above embodiments, refer to Figure 3A seesaw 600 can also be set on the outer side of the support frame 200, with the upper end of the seesaw 600 set outward and the lower end provided with a second inverted buckle 610 facing inward. A hinge seat 240 is set on the outer wall of the support plate 200, and the middle section of the seesaw 600 is rotatably connected to the hinge seat 240. At the same time, a compression spring is set between the upper end of the seesaw 600 and the support plate 200, or a torsion spring is set at the connection between the seesaw 600 and the hinge seat 240. The compression spring or torsion spring makes the upper end of the seesaw 600 always have a tendency to rotate outward, and the second inverted buckle 610 at the lower end of the seesaw 600 can be buckled on the step portion at the lower end of the base plate 100. When the support plate 200 needs to be removed, the upper ends of the seesaw 600 on both sides of the support plate 200 are pressed at the same time to rotate the seesaw 600, and the second inverted buckle 610 at the lower end is disengaged from the step portion, so that the support plate 200 can be taken out.

[0044] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 The elastic component 400 includes a first push block 440, a second push block 450, a spring 420 and a baffle 430. The first push block 440 is connected to the bottom of the mounting plate 300, the baffle 430 is arranged on the bottom plate 100, the second push block 450 is arranged horizontally and movably connected to the bottom plate 100, and the two ends of the spring 420 are respectively connected to the second push block 450 and the baffle 430. The first push block 440 can push the second push block 450 downward so that the second push block 450 squeezes the spring 420 in the direction of the baffle 430. The first push block 440 and the second push block 450 can be connected to the support frame 200 and the bottom plate 100 in the form of a slide slot slider. The first push block 440 is provided with a first guide surface 441, and the second push block 450 is provided with a second guide surface 451. The first guide surface 441 and the second guide surface 451 are parallel. Figure 4 and Figure 5 In the embodiment, the first push block 440 moves in the vertical direction and the second push block 450 moves in the horizontal direction. When the mounting plate 300 and the first push block 440 move downward, the first guide surface 441 of the first push block 440 contacts and squeezes the second guide surface 451 of the second push block 450. Under the action of the first guide surface 441 and the second guide surface 451, the second push block 450 is squeezed and moves in the horizontal direction and squeezes the spring 420, thereby buffering the mounting plate 300. After being installed in place, the interference force between the mounting plate 300 and the chip is reduced or disappears. At this time, the spring 420 pushes the second push block 450 to reset. The second push block 450 drives the first push block 440 to move upward through the second guide surface 451, thereby causing the mounting plate 300 and the chip to move upward and reset.

[0045] According to some embodiments of the present invention, a slide rail 210 is vertically arranged on the side of the support frame 200, and the mounting plate 300 is slidably connected to the slide rail 210. The slide rail 210 is used to reduce the sliding friction between the mounting plate 300 and the support frame 200, and can also play a role in moving and orienting the mounting plate 300, thereby ensuring that the mounting plate 300 always maintains the correct installation angle.

[0046] According to some embodiments of the present invention, a through hole is provided on the side of the slide rail 210, and a limit pin 220 is provided in the through hole. The limit pin 220 can limit the mounting plate 300 from falling off the support frame 200 downward, so as to prevent the mounting plate 300 from losing the pushing action of the spring 420 and falling off when the support frame 200 is removed. When the mounting plate 300 needs to be removed from the support frame 200, the limit pin 220 can be removed from the slide rail 210.

[0047] According to some embodiments of the present invention, a limiting portion 230 is provided above the support frame 200, and the limiting portion 230 is used to limit the upward movement of the mounting plate 300 to prevent the mounting plate 300 from escaping from the support frame 200 from above.

[0048] According to some embodiments of the present invention, an elastic clip 320 is further provided on the side of the mounting plate 300. The elastic clip 320 itself is an elastic plastic part. The elastic clip 320 is used to prevent the chip from falling out of the mounting plate 300. When installing or removing the chip, the elastic clip 320 is pulled toward the outside of the mounting plate 300 to complete the installation and removal of the chip.
