Description

Technical Field

[0001] This invention relates to the field of printer technology, specifically to a printer top cover structure. Background Technology

[0002] Currently, printers generally have both printing and scanning functions.

[0003] For example, the patent application CN201420601421.5, entitled "A Miniature Scanning and Printing All-in-One Machine", discloses a structure in which a print head is arranged in the upper front part of the outer casing, a paper tray is arranged in the rear interior of the outer casing, and a paper holder is located between the outer casing and the top cover. The paper holder is movably hinged to the upper rear part of the outer casing. The front part of the paper holder has a paper pressing surface that cooperates with the side of the print head. There is a through hole on the paper pressing surface. A barcode scanning head and a rubber roller are fixed on the top cover. The barcode scanning head is fixed on the top cover and installed in the scanning channel. After the top cover is closed, the barcode scanning head passes through the scanning channel and aligns with the through hole on the paper pressing surface.

[0004] The printer described above has the scanning assembly mounted on top of the paper tray. When a paper jam occurs or the toner cartridge needs replacing, the scanning assembly must be opened first, followed by the paper tray, a complex and cumbersome process. Therefore, the current printer cover structure needs further improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a printer top cover structure that simplifies the operation process and makes it convenient to use by linking the scanning component and the top cover to open synchronously.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A printer top cover structure includes a top cover and a scanning component disposed on the top of the printer body. A mounting base is provided on the top of the printer body. The rear edge of the top cover is rotatably connected to the mounting base. The scanning component is located on the top cover and its rear part is rotatably connected to the mounting base. A mating structure is provided between the lower surface of the scanning component and the upper surface of the top cover, which allows the top cover to flip backward as the scanning component flips backward.

[0008] Preferably, the rear edge of the upper cover is rotatably connected to the mounting base via a first horizontally arranged pivot, and the rear of the scanning component is rotatably connected to the mounting base via a second pivot. The first pivot is located on the lower front side of the second pivot. The mating structure is a movable structure that allows the scanning component and the upper cover to slide back and forth. With this structure, the first and second pivots respectively constrain the rotational support positions of the upper cover and the scanning component. During the opening and flipping process of the scanning component, the rotational stroke of the scanning component is greater than that of the upper cover. This invention uses a movable structure to eliminate the interference caused by the difference in rotational stroke, so that the scanning component can smoothly drive the upper cover to flip open during the opening and flipping process.

[0009] Preferably, the mating structure also forms a limiting structure for constraining the upper cover onto the scanning component. During the upward opening of the scanning component, the mating structure, in its active state, applies an upward force to the upper cover due to its limiting effect. This invention utilizes a movable structure to constrain the upper cover onto the scanning component, ensuring that the upper cover is always linked with the scanning component. Simultaneously, the limiting position changes the direction of the force applied to the upper cover at any time, thereby causing the upper cover to synchronously flip and open during the opening and flipping process of the scanning component.

[0010] Preferably, the lower surface of the scanning component is provided with a connecting arm that protrudes downward and extends forward and backward. The inner side of the connecting arm is provided with a sliding groove that extends from front to back and gradually slopes downward. Correspondingly, the upper surface of the upper cover is provided with a sliding post that guides and engages with the sliding groove. The engagement of the sliding post and the sliding groove allows the upper cover to always move in conjunction with the scanning component, forming a limiting structure. The rolling engagement of the sliding post and the sliding groove ensures smooth movement of the upper cover relative to the scanning component and provides adjustment space for the force applied by the scanning component to the upper cover to be adjusted at any time. Thus, during the opening and flipping process of the scanning component, the upper cover is driven to flip and open synchronously.

[0011] Preferably, the front end of the slide groove is open, and the rear end of the slide groove has a horizontally arranged section for constraining the sliding column. The open end forms a V-shaped structure with a larger front end and a smaller rear end, facilitating the sliding column to slide into the slide groove during assembly. This structure facilitates the cooperation between the sliding column and the slide groove. The horizontal section can temporarily limit the movement of the upper cover when both the scanning component and the upper cover are open, preventing sliding between the upper cover and the scanning component without external force.

[0012] Preferably, the upper surface of the top cover is provided with a mounting plate that is arranged near the connecting arm and extends upward, and the sliding post is disposed on the outer side wall of the mounting plate. Preferably, the mounting plate is formed into a triangular structure with the tip pointing upward. When the scanning assembly and the top cover are in the printer body, the rear edge of the mounting plate is in the same inclination trend as the slide groove, and the sliding post is located at the tip of the triangular structure. The above structure facilitates the setting of the sliding post, and the triangular structure facilitates the support of the scanning assembly, improving the compactness and reliability of the fit between the scanning assembly and the top cover.

[0013] Preferably, the mounting base includes a first support portion and a second support portion extending upward from both sides of the top of the printer body. A space for mounting the top cover is formed between the first support portion and the second support portion. The inner sides of the first support portion and the second support portion are recessed downward to accommodate a first rotating shaft, and the rear edges of the first support portion and the second support portion protrude upward to accommodate a second rotating shaft. This structure, in conjunction with the positioning of the first and second rotating shafts, provides conditions for stable linkage between the scanning assembly and the top cover.

[0014] Preferably, the first rotating shaft is laterally positioned in the middle and rear part of the mounting base, and correspondingly, the rear edge of the upper cover is provided with a first shaft hole that rotatably engages with the first rotating shaft. Preferably, the rear ends of the first support part and the second support part are provided with a second rotating shaft that is suspended and arranged laterally, and correspondingly, the lower surface of the scanning component is recessed with a second shaft hole that rotatably engages with the second rotating shaft. The upper and lower surfaces of the first rotating shaft are arc surfaces, and the front and rear surfaces are vertically arranged planes, and the first shaft hole is a C-shaped groove with its opening facing backward; the upper and lower surfaces of the second rotating shaft are horizontally arranged planes, and the front and rear surfaces are arc surfaces, and the second shaft hole is a C-shaped groove with its opening facing downward. The above structure facilitates production and assembly. At the same time, when the scanning component and the upper cover are open or closed, the structure of the rotating shaft provides temporary support to achieve corresponding hovering or holding actions, thereby improving the user experience.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The present invention provides a matching structure between the lower surface of the scanning component and the upper surface of the upper cover, which enables the upper cover to flip backward as the scanning component flips backward. During the process of the scanning component flipping open, the upper cover moves back and forth with the scanning component while flipping with the scanning component, thereby realizing that the upper cover automatically opens with the scanning component, simplifying the user's operation process and making it more convenient to use.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms 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 this application 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 this application.

[0025] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0029] like Figures 1-6 As shown, the printer cover structure of this embodiment includes a cover 2 and a scanning component 3 located on the top of the printer body 1. A mounting base 4 is provided on the top of the printer body 1. The rear edge of the cover 2 is rotatably connected to the mounting base 4. The scanning component 3 is located on the cover 2 and its rear part is rotatably connected to the mounting base 4. A mating structure is provided between the lower surface of the scanning component 3 and the upper surface of the cover 2, which allows the cover 2 to flip backward as the scanning component 3 flips backward.

[0030] The rear edge of the upper cover 2 is rotatably connected to the mounting base 4 via a horizontally arranged first rotating shaft 10. The rear of the scanning component 3 is rotatably connected to the mounting base 4 via a second rotating shaft 20. The first rotating shaft 10 is located on the lower front side of the second rotating shaft 20. The mating structure is a movable structure that allows the scanning component 3 and the upper cover 2 to slide back and forth. With the above structure, the first rotating shaft 10 and the second rotating shaft 20 respectively constrain the rotational support positions of the upper cover 2 and the scanning component 3. During the opening and flipping process of the scanning component 3, the rotational stroke of the scanning component 3 is greater than the rotational stroke of the upper cover 2. This invention uses a movable structure to eliminate the interference caused by the difference in rotational stroke, so as to enable the scanning component 3 to smoothly drive the upper cover 2 to flip open during the opening and flipping process.

[0031] The cooperating structure simultaneously forms a limiting structure for constraining the upper cover 2 onto the scanning component 3. During the upward opening of the scanning component 3, the cooperating structure, in its active state, applies an upward force to the upper cover 2 due to its limiting effect. This embodiment utilizes the movable structure to constrain the upper cover 2 onto the scanning component 3, ensuring that the upper cover 2 is always linked with the scanning component 3. Simultaneously, the direction of the force applied to the upper cover 2 is changed at any time by utilizing the limiting position, thereby causing the upper cover 2 to synchronously flip and open during the opening and flipping process of the scanning component 3.

[0032] The lower surface of the scanning component 3 is provided with a downwardly protruding connecting arm 31 that extends forward and backward. The inner side of the connecting arm 31 is provided with a sliding groove 32 that extends from front to back and gradually slopes downward. Correspondingly, the upper surface of the upper cover 2 is provided with a sliding post 21 that can guide and cooperate with the sliding groove 32. The sliding post 21 cooperates with the sliding groove 32, which enables the upper cover 2 to always be linked with the scanning component 3 and form a limiting structure. The rolling cooperation between the sliding post 21 and the sliding groove 32 makes the upper cover 2 move smoothly relative to the scanning component 3, and provides adjustment space for the force applied by the scanning component 3 to the upper cover 2 to adjust its direction at any time. Thus, when the scanning component 3 opens and flips, it drives the upper cover 2 to flip and open synchronously.

[0033] The slide groove 32 has an opening 321 at its front end and a horizontal portion 322 at its rear end, which is horizontally arranged and constrains the sliding column 21. The opening 321 forms a V-shaped structure with a larger front end and a smaller rear end, so that the sliding column 21 can slide into the slide groove 32 during assembly. With the above structure, it is easy to realize the cooperation between the sliding column 21 and the slide groove 32. The horizontal portion 322 can temporarily limit the upper cover 2 when both the scanning component 3 and the upper cover 2 are open, so that the upper cover 2 and the scanning component 3 will not slide without external force.

[0034] The upper surface of the top cover 2 is provided with a mounting plate 22 that is arranged near the connecting arm 31 and extends upward. A sliding post 21 is provided on the outer side wall of the mounting plate 22. The mounting plate 22 is shaped into a triangular structure with the tip pointing upward. When the scanning assembly 3 and the top cover 2 are placed on the printer body 1, the rear edge of the mounting plate 22 is inclined in the same direction as the slide groove 32, and the sliding post 21 is located at the tip of the triangular structure. The above structure facilitates the setting of the sliding post 21, and the triangular structure facilitates the support of the scanning assembly 3, improving the compactness and reliability of the fit between the scanning assembly 3 and the top cover 2.

[0035] Mounting base 4 includes a first support portion 41 and a second support portion 42 extending upward from both sides of the top of the printer body 1. A space for mounting the top cover 2 is formed between the first support portion 41 and the second support portion 42. The inner sides of the first support portion 41 and the second support portion 42 are recessed downward to accommodate the first rotating shaft 10, and the rear edges of the first support portion 41 and the second support portion 42 protrude upward to accommodate the second rotating shaft 20. This structure, in conjunction with the positioning of the first rotating shaft 10 and the second rotating shaft 20, provides conditions for stable linkage between the scanning assembly 3 and the top cover 2.

[0036] The first rotating shaft 10 is horizontally positioned at the rear middle part of the mounting base 4. Correspondingly, the rear edge of the upper cover 2 is provided with a first shaft hole 23 that rotatably engages with the first rotating shaft 10. The rear ends of the first support part 41 and the second support part 42 are provided with a suspended and horizontally arranged second rotating shaft 20. Correspondingly, the lower surface of the scanning component 3 is recessed with a second shaft hole 33 that rotatably engages with the second rotating shaft 20. The upper and lower surfaces of the first rotating shaft 10 are arc surfaces, and the front and rear surfaces are vertically arranged planes. The first shaft hole 23 is a C-shaped groove with its opening facing rearward. The upper and lower surfaces of the second rotating shaft 20 are horizontally arranged planes, and the front and rear surfaces are arc surfaces. The second shaft hole 33 is a C-shaped groove with its opening facing downward. This structure facilitates production and assembly. Furthermore, when the scanning component 3 and the upper cover 2 are open or closed, the rotating shaft structure provides temporary support to achieve corresponding hovering or holding actions, improving the user experience.

[0037] In this embodiment, a mating structure is provided between the lower surface of the scanning component 3 and the upper surface of the upper cover 2, which enables the upper cover 2 to flip backward as the scanning component 3 flips backward. During the process of the scanning component 3 flipping open, the upper cover 2 moves back and forth with the scanning component 3 while flipping with the scanning component 3, thereby realizing that the upper cover 2 automatically opens with the scanning component 3, simplifying the user's operation process and making it more convenient to use.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
