[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0027] Reference below Figures 1-6 A toner cartridge according to an embodiment of the present invention is described.

[0028] like Figure 1-Figure 5 As shown, the toner cartridge includes a chip assembly 1 and a cartridge body 2. A side cover 3 is mounted on the cartridge body 2, and a mounting frame 4 is provided on the side cover 3. The chip assembly 1 is detachably mounted within the mounting frame 4. A first opening 401 is formed on one side of the mounting frame 4. A connecting portion and a retaining portion 403 are provided at the bottom of the mounting frame 4. The chip assembly 1 enters the mounting frame 4 through the first opening 401, engages with the retaining portion 403, and connects to the connecting portion.

[0029] For the convenience of description, Figure 1 As shown, the direction from the side of the mounting frame 4 having the first opening 401 to the opposite side is called the Y direction, the directions of the other two opposite sides of the mounting frame 4 are called the P direction, and the direction from the bottom to the top of the mounting frame 4 is called the Z direction.

[0030] In the implementation scheme shown in the present utility model, the chip component 1 is installed from one side of the mounting frame 4 through the first opening 401 toward the other side of the mounting frame 4, and is limited and constrained by the limiting portion 403 in the mounting frame 4 to prevent the chip component 1 from moving in the P direction, and is fixedly connected to the connecting portion in the mounting frame 4 to prevent the chip component 1 from moving in the -Z direction, thereby achieving the fixation of the chip component 1 on the mounting frame 4.

[0031] In some embodiments, the box body 2 further includes a frame body, and the side cover 3 is provided on a side of the frame body.

[0032] According to the toner cartridge of the embodiment of the present invention, the chip assembly 1 is installed into the mounting frame 4 through the first opening 401 along the Y direction of the mounting frame 4, and the chip assembly 1 is respectively limited and fixedly connected with the limiting portion 403 and the connecting portion at the bottom of the mounting frame 4, thereby realizing the positioning constraint and fixation of the chip assembly 1, making the chip assembly 1 easy to install, firmly installed and stable. Moreover, compared with the prior art, when the user needs to replace the chip, he only needs to take out the chip assembly 1 along the -Y direction through the first opening 401, and then install the new chip assembly 1 into the mounting frame 4 again through the first opening 401. This process is convenient to operate and greatly improves the convenience of installing and removing the chip assembly 1. In addition, compared with the installation angle of placing the chip assembly 1 in the mounting frame 4 from the -Z direction, the operation convenience is achieved.

[0033] According to the first embodiment of the present invention, the connecting portion is a snap-fit ​​portion 402 , which is disposed near the first opening 401 , and the limiting portion 403 is disposed on a side of the snap-fit ​​portion 402 away from the first opening 401 .

[0034] With this arrangement, when the user needs to replace the chip, the locking portion 402 in the mounting frame 4 is loosened through the first opening 401 to take out the chip assembly 1 along the -Y direction, and then the new chip assembly 1 is installed into the mounting frame 4 through the first opening 401 again. This process greatly facilitates the operation of the staff.

[0035] Furthermore, along the direction from the bottom to the top of the installation frame 4 , the top end of the engaging portion 402 is higher than the top end of the limiting portion 403 .

[0036] like Figure 3-Figure 4 In the illustrated embodiment, the top of the engaging portion 402 along the Z direction is higher than the top of the limiting portion 403. This allows the chip assembly 1 to be installed at an angle α with the bottom of the mounting frame 4 when it enters the mounting frame 4 from the first opening 401 in the Y direction. After being engaged with the limiting portion 403, the chip assembly 1 is installed by pressing it in the -Z direction to engage the engaging portion 402. This facilitates quick positioning of the chip assembly 1 and the limiting portion 403. Compared to the prior art method of placing the chip assembly 1 vertically in the mounting frame 4 from the -Z direction, this method effectively improves operational convenience.

[0037] According to some embodiments of the present invention, the locking portion 402 is provided with an abutting surface that abuts against the chip component 1, and the limiting portion 403 is provided with a limiting support surface 4031 that limits the chip component 1. Along the direction from the bottom to the top of the mounting frame 4, the limiting support surface 4031 and the abutting surface are located in the same horizontal plane.

[0038] like Figure 3-Figure 4In the embodiment shown, when the chip component 1 is installed in the mounting frame 4 from the Y direction and at an angle α, the limiting support surface 4031 of the limiting portion 403 contacts and supports the bottom surface of the chip component 1, and the abutting surface of the locking portion 402 abuts against the surface of the chip component 1. In addition, the limiting support surface 4031 and the abutting surface are located in the same horizontal plane, so that the chip component 1 is horizontally located in the mounting frame 4 in the Z direction, thereby effectively preventing the chip component 1 from moving in the Z direction.

[0039] According to some embodiments of the present invention, along the direction from the bottom to the top of the installation frame 4 , the top of the engaging portion 402 is higher than the bottom of the first opening 401 .

[0040] With such arrangement, when the chip assembly 1 is installed along the Y direction, it is convenient for the chip assembly 1 to overlap above the limiting portion 403 and the locking portion 402 at an angle α, and when the chip assembly 1 needs to be replaced, it is convenient to operate the locking portion 402 through the first opening 401, thereby removing the chip assembly 1, further improving the operational convenience of installing and removing the chip assembly 1.

[0041] According to another embodiment of the present invention, see Figure 6 As shown, the connecting portion is a threaded rod 407 having an external thread formed thereon, and the chip assembly 1 is sleeved and supported on the threaded rod 407. The toner cartridge further includes a nut threadedly connected to the threaded rod 407 to fix the chip assembly 1 between the nut and the threaded rod 407.

[0042] According to another embodiment of the present invention, the connecting portion is a connecting column with a mounting hole formed thereon. The toner cartridge further comprises a connecting piece which passes through the chip assembly 1 and is fixedly connected to the mounting hole.

[0043] According to some embodiments of the present invention, the chip assembly 1 includes: a chip and a chip substrate 102, the chip is provided with an electrical contact portion 101, the chip is mounted on the chip substrate 102, the chip substrate 102 is provided with a limiting matching portion 1021 for limiting matching with the limiting portion 403, and the chip substrate 102 is connected to the connecting portion. Figure 1 and Figure 5 In the illustrated embodiment, the chip substrate 102 is engaged with the limiting portion 403 and the engaging portion 402 in a limiting and locking manner, respectively.

[0044] According to some embodiments of the present invention, the limiting portion 403 is a limiting column, the limiting matching portion 1021 is a limiting hole, and a support platform 4032 for supporting the chip substrate 102 is formed at the lower portion of the limiting column.

[0045] In a specific embodiment, Figure 2-Figure 5As shown, the limiting portion 403 is a limiting post, and correspondingly, the limiting mating portion 1021 is a limiting hole. A support platform 4032 is formed below the limiting post, so that the limiting hole of the chip substrate 102 is supported on the support platform 4032 after the limiting post is passed through. In other words, the limiting post prevents the chip substrate 102 from moving in the P direction while also supporting the chip substrate 102.

[0046] According to some embodiments of the present invention, a second opening 404 is formed on the other side of the mounting frame 4, and the second opening 404 is arranged opposite the first opening 401. Furthermore, the chip assembly 1 further includes a chip holder 103, which is mounted on the chip substrate 102. A third opening 1031 is formed on a side of the chip holder 103 facing away from the first opening 401. The electrical contact portion 101 is disposed within the chip holder 103 and faces the third opening 1031. After the chip assembly 1 enters the mounting frame 4, the chip holder 103 engages with the second opening 404.

[0047] See Figure 5 As shown, the mounting frame 4 has a second opening 404 formed on a side opposite to the side having the first opening 401. When the chip assembly 1 enters the mounting frame 4 from the Y direction, the chip holder 103 is ultimately engaged at the second opening 404, allowing the electrical contact portion 101 within the chip holder 103 to electrically contact an external electrical connector through the third opening 1031 and the second opening 404. Furthermore, the engagement of the chip holder 103 with the second opening 404 provides a positioning constraint for the chip assembly 1 when it is installed from the Y direction.

[0048] Furthermore, a positioning portion is provided on at least one side of the chip holder 103 perpendicular to the side having the third opening 1031 , and the positioning portion abuts against an inner surface of the side of the mounting frame 4 having the second opening 404 .

[0049] That is, the chip holder 103 is provided with a positioning portion on one side along the P direction and / or on one side along the -P direction. When the chip assembly 1 is installed from the Y direction through the first opening 401, the positioning portion abuts and engages with the inner surface of the side of the mounting frame 4 having the second opening 404. At this point, the chip substrate 102 reaches the appropriate position. The chip substrate 102 is then pressed in the -Z direction to securely engage the engaging portion 402. In other words, the positioning portion pre-installs the chip substrate 102 in the Y direction.

[0050] According to some embodiments of the present invention, the limiting portion 403 is a limiting column, the limiting matching portion 1021 is a limiting hole, and the limiting hole is an oblong hole, the length of which is along the direction from one side of the mounting frame 4 having the first opening 401 to the other side.

[0051] It can be understood that when the chip substrate 102 is installed at an angle α from the Y direction, the limiting hole on the chip substrate 102 is penetrated into the limiting column. While limiting the movement of the chip substrate 102 in the P direction and the -P direction, the limiting column causes the limiting hole of the chip substrate 102 to continue to move along the Y direction until the positioning portion on the chip seat 103 abuts and fits with the inner surface of the side of the mounting frame 4 having the second opening 404. At this time, the chip substrate 102 reaches the appropriate position, and then the chip substrate 102 is pressed in the -Z direction to make the chip substrate 102 tightly fit with the locking portion 402.

[0052] According to some embodiments of the present invention, the mounting frame 4 includes: a bottom plate 405 and multiple side plates 406, the multiple side plates 406 are mutually enclosed and connected and are connected to the bottom plate 405, and a snap-fit ​​portion 402 and a limiting portion 403 are provided on the bottom plate 405, and a first opening 401 is formed on one of the side plates 406.

[0053] Therefore, the chip assembly 1 is installed at an angle α along the Y direction through the first opening 401, and the chip assembly 1 is positioned and fixed by respectively limiting and cooperating with the limiting portion 403 and the connecting portion at the bottom of the installation frame 4, so as to achieve the positioning constraint and fixation of the chip assembly 1, making the chip assembly 1 easy to install, firmly installed and stable. Compared with the existing technology, when the user needs to replace the chip assembly 1, it is only necessary to take out the chip assembly 1 along the -Y direction through the first opening 401, and then install the new chip assembly 1 into the installation frame 4 through the first opening 401 again. This process is convenient to operate and greatly improves the convenience of installing and removing the chip assembly 1. In addition, compared with the installation angle of placing the chip assembly 1 in the installation frame 4 from the -Z direction, operability is effectively achieved.
