Description

Technical Field

[0001] This application relates to the field of printers, and more particularly to a printer control box. Background Technology

[0002] The printer control box is the core control component of a printer, integrating various functional components such as driver chips, power modules, and circuit modules. However, in current technology, printer control boxes typically employ an integrated design, placing all internal components within a single, unified cavity. When a module needs repair or replacement, maintenance personnel must completely open the entire flip cover, exposing non-target components in other compartments. These components are susceptible to dust contamination, external force, and other interference, affecting the safety and subsequent operational stability of these non-repairable components. Furthermore, the opening method of the flip cover also presents limitations. When opening multiple flip covers, traditional maintenance personnel spend a significant amount of time on unlocking operations, not only extending repair time but also potentially preventing the flip covers from opening smoothly due to structural issues, thus impacting the efficiency of repairing the internal components of the control box.

[0003] Therefore, there is a need for a printer control box that can protect components in different zones during maintenance and provides a convenient way to unlock the flip cover. Utility Model Content

[0004] In view of this, it is necessary to provide a printer control box that can protect the components in different partitions during maintenance and provides a convenient unlocking flip cover to solve the above problems.

[0018] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] An embodiment of this application provides a printer control box, the control box comprising: A control box body, wherein the control box body has at least two receiving cavities; At least two flip-top shells, one of which corresponds to one of the receiving cavities, and the flip-top shell has a movable end that is rotatably connected to the control box body; A latching assembly is located on the side of the flip cover away from the movable end. The latching assembly has a limiting block that moves in a first direction. The control box body has a latching groove. The limiting block can extend into or slide out of the latching groove to lock or unlock the flip cover. When the flip cover is unlocked, it is rotated to cover or expose the receiving cavity.

[0021] The printer control box described above features at least two accommodating cavities within its main body, each housing a different functional module. This allows for maintenance by opening only the cover of the corresponding module, preventing exposure of non-target components, protecting against dust and external interference, and safeguarding the safety and stability of other components. Furthermore, a movable limiting rod is incorporated into the latching assembly of each cover, enabling locking or unlocking by inserting or sliding it into the latching slot. This facilitates easy unlocking of each cover, reducing unlocking time and improving maintenance efficiency.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] according to Figures 1-6 This application provides a printer control box 100, which includes: a control box body 10, at least two flip-top shells 20 and a snap-fit ​​assembly 30.

[0024] The control box body 10 has at least two receiving cavities 11. A flip cover 20 corresponds to one of the receiving cavities 11, and the flip cover 20 has a movable end 21, which is rotatably connected to the control box body 10. A latching assembly 30 is located on the side of the flip cover 20 away from the movable end 21. The latching assembly 30 has a limiting block 31 that moves along a first direction F1. The control box body 10 has a latching groove 12, and the limiting block 31 can extend into or slide out of the latching groove 12 to lock or unlock the flip cover 20.

[0025] When the flip cover 20 is unlocked, the flip cover 20 is rotated to cover or expose the receiving cavity 11.

[0026] Specifically, by using at least two separate accommodating cavities 11, different functional modules of the printer, such as the main control board, power module, or interface board, can be independently housed in different accommodating cavities 11. During maintenance, when only one module needs to be inspected or replaced, targeted operations can be performed, ensuring that the components in the other accommodating cavities 11 remain in a closed and protected state. This effectively avoids dust contamination and accidental physical damage caused by complete exposure, greatly ensuring the safety of the internal components and the stability of long-term operation.

[0027] Furthermore, the control box is equipped with at least two flip-top covers 20 corresponding to the number of accommodating cavities 11. Each flip-top cover 20 is specifically responsible for sealing a particular accommodating cavity 11. The flip-top cover 20 is rotatably connected to the control box body 10 via its movable end 21. This connection is typically achieved by means of a pivot or hinge structure, allowing the flip-top cover 20 to rotate around the pivot or hinge structure. When the flip-top cover 20 is closed, it can flatly cover the opening of the accommodating cavity 11; when it needs to be opened, it needs to rotate around the pivot or hinge structure to expose the accommodating cavity 11 below for operation of the internal structure.

[0028] Furthermore, a latching assembly 30 is provided on the side of the flip cover 20 away from its rotation center, i.e., the movable end 21, to fix and release the flip cover 20 from the control box body 10. The latching assembly 30 has a limiting block 31 that moves linearly along a first direction F1. Correspondingly, a latching groove 12 is provided on the control box body 10 at a position corresponding to the end point of the travel of the limiting block 31. It should be noted that the first direction F1 is the reciprocating movement direction of the limiting block 31 toward and away from the latching groove 12.

[0029] When the flip cover 20 is closed, the limiting block 31 extends into and is engaged in the latching groove 12 of the control box body 10, thereby locking the flip cover 20 through mechanical interlocking to prevent it from being opened due to vibration or accident; when it needs to be opened, the limiting block 31 is moved in the opposite direction F1 by external operation and slides out from the latching groove 12, and the locking state is released.

[0030] Through the above design, the printer control box in this embodiment not only effectively isolates the maintenance area and prevents other components from being exposed, but also provides a convenient unlocking and flip-top method, greatly shortening maintenance time and improving maintenance efficiency. Furthermore, the structural design of all the latching components 30 ensures the stability and smooth operation of the flip-top cover 20, further enhancing the reliability of the control box and the user experience.

[0031] In one specific embodiment, the limiting block 31 is further provided with a movable part 311, which is recessed from the end face of the limiting block 31 along the thickness direction of the limiting block 31, and the movable part 311 is provided on the side of the limiting block 31 away from the receiving cavity 11.

[0032] The flip cover 20 has an opening 22 that extends through the thickness of the flip cover 20, and the movable part 311 is disposed opposite to the opening 22.

[0033] Specifically, the movable part 311 can be a groove or a finger-pressure surface. By setting the movable part 311 on the limiting block 31 and engaging with the movable opening 22 on the flip cover 20, a manual unlocking mechanism that can be operated directly without additional tools is provided. When it is necessary to open the flip cover 20, the user's or maintenance personnel's fingers can directly contact and press the movable part 311 located on the limiting block 31 through the movable opening 22. This design makes operation simpler, requiring no additional tools to assist in unlocking, greatly facilitating the maintenance and use of the device.

[0034] Furthermore, when the movable part 311 is pressed, the limiting block 31 is pushed to slide along the direction of the latching groove 12, thereby unlocking the latching groove 12. After the limiting block 31 disengages from the latching groove 12, the flip cover 20 can be opened through the rotating end, revealing the receiving cavity 11 inside the control box.

[0035] Furthermore, the opening of the flip cover 20 relies on the interaction between the limiting block 31 and the latching groove 12. The design of the movable part 311 provides a directly operable area, allowing the limiting block 31 to slide within the latching groove 12. After unlocking, the flip cover 20 can rotate around the movable end 21, opening the receiving cavity 11 for easy module maintenance and replacement.

[0036] In one specific embodiment, the latching assembly 30 further includes: a positioning member 32 and an elastic member (not shown in the figure).

[0037] The positioning member 32 and the limiting block 31 are disposed adjacent to each other on the flip cover 20, and the positioning member 32 is disposed at the end of the limiting block 31 away from the snap-fit ​​groove 12. An elastic member is sandwiched between the positioning member 32 and the limiting block 31, so that the elastic member presses the limiting block 31 into the snap-fit ​​groove 12; the positioning member 32 and the limiting block 31 are spaced apart.

[0038] Specifically, the limiting block 31, as the core component of the latching assembly 30, is located inside the flip cover 20 and, together with the positioning member 32 and the elastic member, achieves the locking and unlocking of the flip cover 20. The positioning member 32 is arranged adjacent to the limiting block 31 and is located at the end of the limiting block 31 away from the latching groove 12. The function of the positioning member 32 is to further constrain the position of the limiting block 31, ensuring that the limiting block 31 can accurately slide into the latching groove 12 for locking.

[0039] Furthermore, an elastic element is sandwiched between the positioning element 32 and the limiting block 31. In this embodiment, the elastic element is a spring structure. The space between the positioning element 32 and the limiting block 31 accommodates and provides a position for the elastic element. When the elastic element is in a certain elastic state, its elastic force will continuously compress the limiting block 31 located on one side, thereby causing the limiting block 31 to tend to extend into the latching groove 12.

[0040] The function of the elastic element is to provide an elastic force to press the limiting block 31 to slide towards the latching groove 12, so that the limiting block 31 can smoothly extend into the latching groove 12, thereby achieving the locking of the flip cover 20.

[0041] In summary, when the user closes the flip cover 20, the end of the limiting block 31 facing the latching groove 12 is squeezed upon contacting the edge of the control box body 10, thus overcoming the elastic force of the elastic element and moving backward. Once the flip cover 20 is closed in place, the limiting block 31 aligns with the latching groove 12, and the accumulated elastic potential energy of the elastic element is immediately released, pushing the limiting block 31 quickly and accurately into the latching groove 12 to achieve automatic locking. When unlocking, the user needs to actively apply external force to the limiting block 31 to compress the elastic element and make it exit the latching groove 12; when the external force is removed, the elastic element can immediately push the limiting block 31 back to the initial position for locking.

[0042] In one specific embodiment, the positioning member 32 has a first positioning rod 321 formed from an extension of the positioning member 32 along the first direction F1.

[0043] The limiting block 31 has a second positioning rod 312 extending along the first direction F1. The first positioning rod 321 is opposite to and coaxially arranged with the second positioning rod 312. One end of the elastic member is sleeved on the first positioning rod 321, and the other end is sleeved on the second positioning rod 312.

[0044] Specifically, the positioning member 32, fixedly mounted on the flip cover 20, has a cylindrical first positioning rod 321 integrally extending from the end of its body facing the limiting block 31 along the first direction F1. Similarly, a cylindrical second positioning rod 312 integrally extends from the end of the limiting block 31 near the positioning member 32 along the first direction F1. The axis of the first positioning rod 321 coincides with the axis of the second positioning rod 312, making them spatially opposite and coaxially opposed. This allows the first positioning rod 321 and the second positioning rod 312 to together form a guide post structure penetrating the internal space of the elastic member.

[0045] Furthermore, by setting coaxially opposite first positioning rod 321 and second positioning rod 312, and respectively sleeved on both ends of the elastic element, radial constraint and guidance are provided for the compression and rebound stroke of the elastic element. This ensures that the elastic element undergoes pure axial deformation along the axis of the first positioning rod 321 and the axis of the second positioning rod 312 when under force, completely avoiding radial bending, twisting, or lateral displacement that may occur during compression. This ensures that the elastic force is always transmitted in the correct direction, driving the limiting block 31 to accurately extend into or retract from the snap-fit ​​groove 12.

[0046] In one specific embodiment, the limiting block 31 is further provided with a movable groove 313 recessed along the first direction F1, and the second positioning rod 312 is disposed in the movable groove 313.

[0047] Specifically, the end of the limiting block 31 near the positioning member 32 forms a movable groove 313 with a certain depth. The second positioning rod 312 is an internal component of the movable groove 313. The root of the second positioning rod 312 is connected to the bottom wall of the movable groove 313, and the rod body of the second positioning rod 312 extends from the groove to the outside, thereby maintaining coaxial alignment with the first positioning rod 321 on the positioning member 32.

[0048] Furthermore, the movable groove 313 partially hides the space occupied by the second positioning rod 312 in the axial direction inside the limiting block 31, thereby effectively shortening the total axial length of the entire buckle assembly 30 while ensuring that the second positioning rod 312 has sufficient guide length, saving valuable space inside the control box.

[0049] Furthermore, in the snap-fit ​​assembly 30, the elastic element, sleeved between the first positioning rod 321 and the second positioning rod 312, provides compression. The movable groove 313 constrains the radial movement of the elastic element, ensuring that it does not become unstable under extreme compression, thus preventing potential misalignment or deformation. The second positioning rod 312 and the elastic element together form a two-stage guide, which not only improves the stability of the snap-fit ​​assembly 30 but also prevents unlocking problems caused by excessive compression or uneven sliding of the elastic element.

[0050] In one specific embodiment, the flip cover 20 has a mounting portion 23, which is disposed on the side of the flip cover 20 facing the receiving cavity 11, and the mounting portion 23 and the flip cover 20 surround to form a limiting cavity 24 along the first direction F1, and the limiting block 31 is movable within the limiting cavity 24.

[0051] Specifically, the flip cover 20 has an integrally formed mounting portion 23 for mounting the snap-fit ​​assembly 30 on its inner surface facing the receiving cavity 11. The mounting portion 23 protrudes from the inner surface of the flip cover 20 and, together with the inner wall of the flip cover 20, forms a limiting cavity 24 extending along the first direction F1 and having a defined cross-sectional shape. The limiting cavity 24 structurally forms a guide channel, and the limiting block 31 can slide along the trajectory defined by the limiting cavity 24 formed in the first direction F1.

[0052] Furthermore, when the user presses the limiting block 31 to unlock or release and reset, the side of the limiting block 31 is closely adjacent to or has a very small clearance fit with the inner wall of the limiting cavity 24. This ensures that the limiting block 31 can only move linearly along the first direction F1 of the limiting cavity 24 throughout its entire movement stroke, effectively preventing any form of deflection, tilting or jamming within the cavity.

[0053] In one specific embodiment, the limiting block 31 further has a third positioning rod 314, which is located at the end of the limiting block 31 away from the second positioning rod 312, and the third positioning rod 314 can extend into the buckle groove 12.

[0054] Specifically, the third positioning rod 314 serves as a key mating structure for the limiting block 31 to extend into the latching groove 12, contacting the inner wall of the latching groove 12 to lock the flip cover 20. The structure of the third positioning rod 314 matches the structure of the latching groove 12.

[0055] Furthermore, when the flip cover 20 needs to be unlocked, the user presses the movable part 311 of the limiting block 31 after passing through the movable opening 22, and pushes the limiting block 31 to slide out of the latching groove 12. The third positioning rod 314 will then disengage from the latching groove 12, allowing the flip cover 20 to open smoothly. The function of the third positioning rod 314 is to ensure that the limiting block 31 can accurately lock into the latching groove 12 when the flip cover 20 is closed, and to ensure a smoother disengagement process when unlocking.

[0056] In one specific embodiment, the third positioning rod 314 has a guide surface 3141, which is inclined inward from the distal end of the third positioning rod 314 in the direction toward the opening of the latching groove 12, so that the third positioning rod 314 moves along the first direction F1 and extends into the latching groove 12.

[0057] Specifically, the distal end of the third positioning rod 314, that is, the end that first comes into contact with the latching groove 12, is machined with a guide surface 3141. The guide surface 3141 is an inclined surface that starts from the distal tip or edge of the third positioning rod 314 and is inclined inward at a certain angle along the direction away from the opening of the latching groove 12.

[0058] Furthermore, when the user closes the flip cover 20, even if there is a slight deviation in the closing action, the distal end of the third positioning rod 314 will contact the area around the latching groove 12 on the control box body 10 before other parts. At this time, the inclined guide surface 3141 contacts the structure of the control box body 10, generating a force perpendicular to the inclined surface, as well as a force that pushes the limiting block 31 backward along the first direction F1. This component force along the first direction F1 will overcome the elastic force of the elastic element and push the entire limiting block 31 assembly backward, making room for the rod body of the third positioning rod 314. As the flip cover 20 continues to close, under the continuous guidance of the guide surface 3141, the flip cover 20 is completely closed, and the rod body of the third positioning rod 314 is completely aligned with the latching groove 12. At this time, the limiting block 31, which has been pushed back by the guide surface 3141, will immediately push the third positioning rod 314 forward under the drive of the elastic element, so that it fully extends into the latching groove 12, completing the automatic locking. This process requires no additional force or precise alignment from the user; the closing action itself triggers the locking procedure.

[0059] In one specific embodiment, the control box body 10 includes an abutment portion 13 protruding along the inner wall of the control box body 10. The abutment portion 13 is located at the opening of the control box body 10 near the accommodating cavity 11 and is arranged parallel to the flip cover 20 so that the abutment portion 13 can abut against the flip cover 20.

[0060] Specifically, the abutment portion 13 is a ring-shaped or frame-shaped structure that protrudes vertically from the inner wall of the control box body 10. The abutment portion 13 provides an internal support frame for the closed flip cover 20. When the flip cover 20 is closed and locked by the latching assembly 30, external forces such as user pressure, objects placed on top, or accidental impacts are not directly transmitted to the latching assembly 30, but are first transmitted through the flip cover 20 to the abutment portion 13 below it. The abutment portion 13 directly and effectively distributes this load onto the robust overall frame of the control box body 10.

[0061] Furthermore, when the flip cover 20 is in the closed state, the end face of the abutment portion 13 facing the flip cover 20 is parallel to the inner surface of the flip cover 20 facing the receiving cavity 11, and can achieve full surface contact with the flip cover 20. At the same time, the latching assembly 30 also simultaneously performs a locking action with the latching groove 12.

[0062] In one specific embodiment, the accommodating cavity 11 includes a first accommodating cavity 111 and a second accommodating cavity 112, which are arranged side by side in the control box body 10 along the first direction F1.

[0063] The flip cover 20 includes a first flip cover 201 and a second flip cover 202. The first flip cover 201 is disposed opposite to the first accommodating cavity 111, and the second flip cover 202 is disposed opposite to the second accommodating cavity 112.

[0064] Specifically, in the embodiments of this application, a first accommodating cavity 111 and a second accommodating cavity 112 are provided within the structure of the control box body 10, and these two accommodating cavities 11 are arranged side by side within the control box body 10 along the first direction F1. The first accommodating cavity 111 and the second accommodating cavity 112 are respectively used to accommodate different functional modules or electronic components, such as power modules, drive circuit modules, etc., ensuring that during maintenance, only the flip cover 20 of the corresponding accommodating cavity 11 needs to be opened, avoiding unnecessary exposure of components, thereby protecting other uninvolved modules from external interference such as dust and external forces.

[0065] Furthermore, each accommodating cavity 11 is provided with a corresponding flip cover 20. The first flip cover 201 is positioned opposite the opening of the first accommodating cavity 111 and is responsible for opening and closing the first accommodating cavity 111. Similarly, the second flip cover 202 is positioned opposite the opening of the second accommodating cavity 112 and is independently responsible for opening and closing the second cavity. This design ensures that each flip cover 20 only covers or exposes its corresponding accommodating cavity 11, thereby minimizing the exposure of components in other accommodating cavities 11 and reducing the risks and unnecessary interference during maintenance.

[0066] Furthermore, when only the functional modules placed in the first accommodating cavity 111 need to be maintained or replaced, the maintenance personnel only need to operate the first flip cover 201 independently to unlock and open it. During this process, the second accommodating cavity 112 is in a completely closed environment because its second flip cover 202 is always kept closed and locked, and the components inside are effectively physically isolated and protected.

[0067] Therefore, the printer control box 100 provided above, by providing at least two accommodating cavities 11 within the control box body 10, each accommodating a different functional module, allows only the flip cover 20 of the corresponding module to be opened during maintenance, avoiding exposure of non-target components, preventing dust and external force interference, and protecting the safety and stability of other components. Furthermore, by providing a movable limiting rod in the latching assembly 30 of each flip cover 20, the flip cover 20 can be locked or unlocked by extending into or sliding out of the latching slot 12. This allows each flip cover 20 to be easily unlocked, reducing unlocking operation time and improving maintenance efficiency.

[0068] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
