Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0021] Please refer to Figure 1 and Figure 2 , Figure 1 This is an exploded view of a portion of the structure of a portable printer provided in an embodiment of this application. Figure 2 This is an exploded view of a partial structure of another portable printer provided in an embodiment of this application. The portable printer may include: a bottom shell 100, a mechanism support 200, a side plate 300, and a printing assembly 400.

[0022] The base 100 of the portable printer may have a first support 101 and a second support 102 disposed opposite to each other along the extending direction of the base 100.

[0023] In a portable printer, the core support 200 and the side plate 300 can be set opposite to each other and independently along the extension direction of the bottom shell 100. The bottom of the core support 200 can be detachably connected to the first support member 101, and the bottom of the side plate 300 can be detachably connected to the second support member 102.

[0024] The printing component 400 in the portable printer can be distributed between the mechanism support 200 and the side plate 300, and the printing component 400 can be connected to both the mechanism support 200 and the side plate 300. Here, the mechanism support 200 can be used to mount components such as the drive motor and transmission mechanism.

[0025] In this embodiment, two support members are provided on the bottom shell 100 of the portable printer. The mechanism support 200 and the side plate 300 are independently arranged and can be installed on the two support members of the bottom shell 100 respectively. The printing assembly 400 is assembled between the mechanism support 200 and the side plate 300. In this way, compared with the use of a larger mechanism support and side plate in related technologies, the size of the mechanism support 200 can be effectively reduced. In addition, the independently arranged mechanism support 200 and side plate 300 are easy to assemble and disassemble flexibly. They can be installed and fixed in the bottom shell 100 by connecting to the support members respectively. At the same time, the independent arrangement of the mechanism support and side plate facilitates the overall layout of the internal components of the printer.

[0026] In summary, this application provides a portable printer that may include: a bottom shell, a mechanism support, a side panel, and a printing assembly. By providing two support members on the bottom shell of the portable printer, the mechanism support and side panel are independently configured and can be respectively mounted on the two support members of the bottom shell. The printing assembly is then assembled between the mechanism support and the side panel. This reduces the size of the mechanism support compared to the larger mechanism support and side panel used in related technologies. Furthermore, the independently configured mechanism support and side panel facilitate flexible assembly and disassembly. Their connection to the support members allows for secure installation within the bottom shell. Additionally, the independent arrangement of the mechanism support and side panel facilitates the overall layout of the printer's internal components.

[0027] Optional, such as Figure 2 As shown, the first support member 101 of the bottom shell 100 may be provided with a first connecting hole k1, and the bottom of the mechanism bracket 200 has a second connecting hole k2 that mates with and communicates with the first connecting hole k1. The portable printer may include a first fastener (not shown in the figure), which passes through the first connecting hole k1 and the second connecting hole k2 to connect the mechanism bracket 200 and the first support member 101 of the bottom shell 100. Thus, by the tight fit between the first fastener and the first connecting hole k1 on the first support member 101 and the second connecting hole k2 at the bottom of the mechanism bracket 200, a secure connection between the mechanism bracket 200 and the bottom shell 100 can be achieved. When it is necessary to disassemble the mechanism bracket 200, the first fastener can be separated from the first connecting hole k1.

[0028] And / or, the second support member 102 of the bottom shell 100 may be provided with a third connecting hole k3, and the bottom of the side plate 300 has a fourth connecting hole k4 that mates with and communicates with the third connecting hole k3. The portable printer may include a second fastener (not shown in the figure), which can pass through the third connecting hole k3 and the fourth connecting hole k4 to connect the side plate 300 and the second support member 102 of the bottom shell 100. Thus, by the tight fit between the second fastener and the third connecting hole k3 on the second support member 102 and the fourth connecting hole k4 on the bottom of the side plate 300, a tight connection between the side plate 300 and the bottom shell 100 can be achieved. When it is necessary to disassemble the side plate 300, the second fastener can be separated from the third connecting hole k3.

[0029] Here, as Figure 2 The above description uses the following examples: a first connecting hole k1 is provided on the first support member 101 of the bottom shell 100, and a second connecting hole k2 communicating with the first connecting hole k1 is provided at the bottom of the movement bracket 200, with the two connecting holes being engaged by a first fastener; and a third connecting hole k3 is provided on the second support member 102 of the bottom shell 100, and a fourth connecting hole k4 communicating with the third connecting hole k3 is provided at the bottom of the side plate 300, with the two connecting holes being engaged by a second fastener.

[0030] It should be noted that the movement bracket 200 and the first support member 101 in the bottom case 100 can also be connected by a snap-fit ​​connection, and no specific limitation is made here.

[0031] For example, such as Figure 2 As shown, the first support member 101 of the bottom shell 100 is also provided with a first positioning member d1, and the bottom of the movement bracket 200 is provided with a second positioning member d2 that cooperates with the first positioning member d1; the second support member 102 of the bottom shell 100 is also provided with a third positioning member d3, and the bottom of the side plate 300 is provided with a fourth positioning member d4 that cooperates with the third positioning member d3.

[0032] In this application, the first connecting hole k1 on the first support member 101 can be a threaded hole, and the first fastener can be a screw; and / or, the third connecting hole k3 on the second support member 102 can be a threaded hole, and the second fastener can be a screw. In this way, the connection between the movement bracket 200 and the first support member 101, and the connection between the side plate 300 and the second support member 102 can be realized through the cooperation of the screw and the threaded hole.

[0033] For example, the second connecting hole k2 at the bottom of the movement bracket 200 can be a through hole or a threaded hole; the fourth connecting hole k4 at the bottom of the side plate 300 can be a through hole or a threaded hole. It should be noted that in other possible implementations, the first fastener can be connected to the first connecting hole k1 by a snap-fit, and the second fastener can be connected to the third connecting hole k3 by a snap-fit.

[0034] Optional, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of a printing component provided in an embodiment of this application. Figure 4 yes Figure 3 The diagram shows a partial exploded view of the printing assembly. The printing assembly 400 may include a thermal printhead mounting plate 401, a spring plate 402, and multiple elastic elements 403. The thermal printhead mounting plate 401 and the spring plate 402 are disposed opposite to each other. Both ends of the thermal printhead mounting plate 401 and the two ends of the spring plate 402 are connected to the core support 200 and the side plate 300, respectively. The thermal printhead mounting plate 401 may be located on the side of the spring plate 402 facing away from the bottom shell 100. Multiple elastic elements 403 are distributed between the thermal printhead mounting plate 401 and the elastic elements 403, with both ends of each elastic element 403 abutting against the thermal printhead mounting plate 401 and the spring plate 402, respectively. Each elastic element 403 can provide an elastic force to the thermal printhead mounting plate 401 in a direction away from the spring plate. Thus, a uniform elastic force can be provided to the thermal printhead mounting plate 401 by the multiple elastic elements 403.

[0035] In this embodiment, the elastic element 403 is a helical spring. The printing assembly 400 further includes multiple positioning pins 404 and multiple retaining rings 405. The elastic plate 402 has a through hole k5. One end of the positioning pin 404 is fastened to the thermal printhead mounting plate 401, and the other end of the positioning pin 404 passes through the through hole k5 of the elastic plate 402 and is located on the side of the elastic plate 402 opposite to the thermal printhead mounting plate 401. The retaining ring 405 can be engaged with the other end of the positioning pin 404, and the outer diameter of the retaining ring 405 is larger than the inner diameter of the through hole k5. The helical spring is sleeved on the circumferential side of the positioning pin 404. Here, multiple helical springs correspond one-to-one with multiple positioning pins 404, and multiple positioning pins 404 correspond one-to-one with multiple retaining rings 405. In this way, by sleeved on the positioning pin 404, the helical spring can be effectively prevented from shifting during paper feeding, ensuring smooth printing and printing effect.

[0036] Optional, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of a portable printer provided in an embodiment of this application. Figure 6 yesFigure 5 The diagram shows a partially exploded view of the portable printer. The portable printer may further include: a top cover 500 and a paper limiter 600 that are fastened to the bottom housing 100. The extension direction of the top cover 500 is parallel to the extension direction of the bottom housing 100. The top cover 500 has a sliding groove c1 extending along its extension direction. The paper limiter 600 is located on the top of the top cover 500 and can be slidably connected along the sliding groove c1. This slidable connection between the paper limiter 600 and the top cover 500 allows for the accommodating of paper rolls of different sizes, improving the printer's practicality. Furthermore, the paper limiter 600 ensures that the printing paper enters the printing assembly 400 along the paper feed path for printing without shifting, thus guaranteeing print quality.

[0037] For example, the portable printer may also include a flip cover 700 disposed adjacent to the top cover 500, with one side of the flip cover 700 forming a paper path between the top cover 500 and one side of the top cover 500.

[0038] Please participate in this application. Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of a paper limiter provided in an embodiment of this application. Figure 8 yes Figure 6 This is a partially enlarged schematic diagram at point A. There are two sliding grooves c1 arranged along the width of the upper cover 500, and the opening direction of each sliding groove c1 can intersect with its extension direction. The two ends of the paper limiter 600 each have a hook 601 that engages with the two sliding grooves c1. The side of the paper limiter 600 facing the upper cover 500 has a first limiting member 602, and the side of the upper cover 500 facing the paper limiter 600 has multiple second limiting members 501 arranged along the moving direction of the paper limiter 600. The first limiting member 602 engages with any of the second limiting members 501 to fix the current position of the paper limiter 600. Thus, by aligning the opening directions of the two sliding grooves c1 with their extension directions, the hooks 601 in the paper limiter 600 engaging with the sliding grooves c1 can only slide along the extension direction of the sliding grooves c1 and will not easily detach from the sliding grooves c1. In addition, the cooperation between the first limiting member 602 in the paper limiter 600 and the second limiting member 501 in the upper cover 500 enables the paper limiter 600 to fix the relative position of the paper limiter 600 and the upper cover 500 after it moves to the target position.

[0039] For example, the first limiting member 602 can be an arc-shaped protrusion, and the second limiting member 501 can be a limiting groove provided on the upper cover 500 that matches the shape of the arc-shaped protrusion. Here, the limiting groove can be a groove-shaped structure formed between two auxiliary arc-shaped protrusions with the same shape as the arc-shaped protrusion. In this way, after the arc-shaped protrusion moves into the limiting groove, the cooperation between the two can fix the paper limiter 600. When it is necessary to move the paper limiter 600, a certain force is applied to the paper limiter 600 to separate the arc-shaped protrusion from the limiting groove.

[0040] Optional, please refer to Figure 6 and Figure 9 , Figure 9 This is an exploded view of a portable printer provided in an embodiment of this application. The top cover 500 may have a paper guide slope m1, a top surface m2, and a side surface m3 arranged sequentially. The paper guide slope m1 is close to the printing assembly 400. The two sides of the top surface m2 are smoothly connected to the paper guide slope m1 and the side surface m3, respectively, and the side surface m3 intersects with both the paper guide slope m1 and the top surface m2. Two sliding grooves c1 of the top cover 500 are respectively distributed at the paper guide slope m1 and the side surface m3. Thus, by placing the two sliding grooves c1 at the side surface m3 and the paper guide slope m1, the aesthetic appearance of the portable printer can be improved. It should be noted that the flip cover 700 in the portable printer is correspondingly arranged with the paper guide slope m1, which can provide a certain degree of shielding for the sliding grooves c1 located at the paper guide slope m1.

[0041] Here, as Figure 6 and Figure 7 As shown, the paper limiter 600 includes: a driving part A1 corresponding to the top surface m2 of the upper cover 500, a first bending part A2 corresponding to the paper guiding slope m1 of the upper cover 500, and a second bending part A3 corresponding to the side surface of the upper cover 500. The first bending part A2 and the second bending part A3 are each provided with a hook 601. The two ends of the driving part A1 are fixedly connected to the first bending part A2 and the second bending part A3, respectively. This allows the user to apply driving force to the paper limiter 600 through the driving part A1, facilitating operation. Here, the driving part A1, the first bending part A2, and the second bending part A3 in the paper limiter 600 can be an integral structure.

[0042] In summary, this application provides a portable printer that may include: a bottom shell, a mechanism support, a side panel, and a printing assembly. By providing two support members on the bottom shell of the portable printer, the mechanism support and side panel are independently configured and can be respectively mounted on the two support members of the bottom shell. The printing assembly is then assembled between the mechanism support and the side panel. This reduces the size of the mechanism support compared to the larger mechanism support and side panel used in related technologies. Furthermore, the independently configured mechanism support and side panel facilitate flexible assembly and disassembly. Their connection to the support members allows for secure installation within the bottom shell. Additionally, the independent arrangement of the mechanism support and side panel facilitates the overall layout of the printer's internal components.
