[0001] This utility model belongs to the field of printer technology, specifically relating to a cover opening structure, a housing assembly, and a printer. Background Technology

[0002] A printer is a computer peripheral device that outputs electronic documents or images to paper or other media. It receives digital signals from a computer, mobile phone, or other device and uses printing technology to "print" physical copies of text, graphics, or photographs. There are various types of printers, such as line marker printers, label printers, and invoice printers.

[0003] In related technologies, the printer's top cover and body are connected by a snap-fit ​​button for a convenient opening and closing experience. However, in practice, it has been found that the button is too light to operate, resulting in a poor user experience, and it also exhibits noticeable wobble relative to the top cover. Utility Model Content

[0004] The purpose of this application is to provide a cover opening structure, a housing assembly, and a printer to solve the aforementioned technical problems existing in the prior art.

[0005] This application is implemented as follows: In a first aspect, embodiments of this application provide a cover opening structure applied to a printer. The cover opening structure includes a cover opening key and a spring element. The cover opening key has two relatively distributed rotating parts. The cover opening key is rotatably mounted on a carrier through the two rotating parts, so as to be able to switch between an unlocked position and a locked position. The carrier is the top cover or the body of the printer. When the cover opening key is in the unlocked position, the top cover is unlocked from the body. When the cover opening key is in the locked position, the top cover is locked from the body. The first end of the spring element is connected to the cover opening key, and the second end of the spring element is used to connect to the carrier. Along the extension direction of the rotation axis of the cover opening key, the first end of the spring element is located closer to one of the rotating parts.

Detailed Implementation

[0012] The following description provides many different embodiments or examples for implementing various features of the present invention. The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In current printer products, the cover opening button has a relatively large structural size, which makes it easy for large errors to occur during manufacturing. This can lead to assembly gaps between the cover opening button and the top cover when they are assembled. As a result, even if the cover opening button is properly assembled, it may wobble relative to the top cover, feel light, and have a poor operating experience.

[0015] In view of this, this application provides a cover opening structure 100, which is applied to a printer. See also... Figures 1 to 5 As shown, the lid opening structure 100 includes a lid opening key 110 and an elastic element 120. The lid opening key 110 has two opposing rotating portions 140, as shown in the figure. Figures 1 to 3 As shown. The cover release button 110 is rotatably mounted on the carrier via two rotating parts 140, so that it can be switched between an unlocked position and a locked position.

[0016] The carrier is either the printer's top cover 200 or the printer body 300. The cover opening button 110 is installed on either one. The top cover 200 and the printer body 300 are rotatably connected. By rotating the top cover 200, it can cover the printer body 300 to obstruct it, or it can be removed from the printer body 300 for operation. When the cover opening button 110 is in the unlocked position, the top cover 200 is unlocked from the printer body 300, and the top cover 200 can rotate relative to the printer body 300 for easy operation. When the cover opening button 110 is in the locked position, the top cover 200 and the printer body 300 are locked, and their positions remain stable.

[0017] The cover opening key 110 is rotatably connected to the carrier through two rotating parts 140. The two rotating parts 140 are located on the same straight line, and the direction of the rotation axis of the cover opening key 110 is the arrangement direction of the two rotating parts 140.

[0018] The first end 121 of the elastic element 120 is connected to the cover opening key 110, and the second end 122 of the elastic element 120 is used to connect to the carrier. The elastic element 120 is connected between the cover opening key 110 and the carrier. (See reference...) Figure 4 As shown, the increased damping between the cover-opening key 110 and the carrier ensures that the cover-opening key 110 is stably mounted on the carrier, maintaining a stable relative position between them. Simultaneously, when the cover-opening key 110 rotates relative to the carrier, the relative positions of the two ends of the elastic element 120 change, causing the elastic element 120 to be stretched, thus providing a reset force for the cover-opening key 110. In specific implementations, the elastic element 120 can be a tension spring, a spring-like structure, or similar components.

[0019] For reference Figure 3 As shown, along the extension direction of the rotation axis of the cover opening key 110, the first end 121 of the elastic member 120 is disposed closer to one of the rotating parts 140 and further away from the other rotating part 140.

[0020] The elastic element 120 provides tension to the lid opening button 110. Being closer to one of the rotating parts 140, the elastic element 120 effectively enhances the damping effect between the rotating part 140 and the carrier, further increasing the rotational resistance between them. This improves the feel of the lid opening button 110, preventing it from feeling too light and difficult to operate, and also preventing damage to its structure from being pulled too quickly. Simultaneously, it ensures stable pressure between the rotating part 140 and the carrier, further preventing significant wobbling between the lid opening button 110 and the top cover 200, resulting in a better lid opening and closing experience.

[0021] Compared to placing the elastic element 120 between the two rotating parts 140, offsetting the elastic element 120 between the two rotating parts 140 and using the same specification elastic element 120, the offset elastic element 120 can make the connection between the cover opening key 110 and the carrier more stable, avoiding the need to improve the connection stability between the cover opening key 110 and the carrier by replacing the elastic element 120, which is beneficial to reducing the overall cost.

[0022] In some embodiments of this application, reference may be made to Figure 1 and Figure 2 As shown, the cover opening structure 100 also includes a first fixing part 150, which includes a first connector 151. The first connector 151 is fixed to the cover opening key 110 and is connected to the first end 121 of the elastic member 120.

[0023] The first connector 151 is bent. The structural strength of the first connector 151 is correspondingly improved after bending, enabling it to withstand stronger tensile forces. For example, the first connector 151 includes two parts, which are bent relative to each other. The two parts can be fixed to each other, with one part fixed to the cover key 110; or both parts can be fixed to the cover key 110, further improving the overall structural strength of the first connector 151.

[0024] And / or, the first fixing part 150 further includes a first reinforcing rib 152, which connects the first connector 151 and the cover opening key 110, improving the structural strength of the first connector 151 and enabling it to withstand stronger tensile forces. Simultaneously, the first connector 151 and the first reinforcing rib 152 are fixed to the cover opening key 110. Since the overall structural strength of the cover opening key 110 is improved, the risk of damage to the cover opening key 110 can be correspondingly reduced.

[0025] In some embodiments of this application, the opening structure 100 further includes a snap-fit ​​portion 130 fixed to the opening key 110, as can be seen from... Figure 1 and Figure 2As shown, the carrier is either the printer's top cover 200 or the printer body 300. The cover opening button 110 is connected to either the top cover 200 or the printer body 300, and the latching part 130 is used for snap-fit ​​connection with the other. For example, when the carrier is the printer's top cover 200 and the cover opening button 110 is connected to the top cover 200, the latching part 130 is snap-fit ​​connected to the printer body 300. Alternatively, when the carrier is the printer body 300 and the cover opening button 110 is connected to the printer body 300, the latching part 130 is snap-fit ​​connected to the top cover 200. The printer body 300 and the top cover 200 are snap-fitted together through the cover opening structure 100, which is simple in structure and easy to operate and control. By rotating the cover opening button 110, the position of the latching part 130 is changed, causing the latching part 130 to separate from or snap into the printer body 300 or the top cover 200, thereby switching the cover opening button 110 between the unlocked and locked positions.

[0026] For details, please refer to Figure 8 and Figure 9 As shown, the cover opening button 110 is installed on the top cover 200, and a corresponding slot 320 is provided on the body 300, into which the latching part 130 can be inserted. When the latching part 130 is inserted into the slot 320, the latching part 130 and the slot wall of the slot 320 are mutually restrictive, preventing the top cover 200 from rotating relative to the body 300. By rotating the cover opening button 110 relative to the top cover 200, the position of the latching part 130 in the slot 320 can be adjusted, releasing the restrictive engagement between the two, at which point the top cover 200 can be rotated relative to the body 300.

[0027] In some other embodiments of this application, the body 300 and the top cover 200 can also be magnetically attached, and the magnetic connection between the body 300 and the top cover 200 can be released by rotating the opening button 110.

[0028] In some preferred embodiments, when the opening structure 100 includes a latching portion 130, the opening structure 100 further includes a first fixing portion 150 fixed to the opening key 110, and the first end 121 of the elastic member 120 is connected to the first fixing portion 150. The first fixing portion 150 and the latching portion 130 are offset along the extension direction of the rotation axis of the opening key 110, which can prevent the first fixing portion 150 and the latching portion 130 from being too close together, causing the first fixing portion 150 to affect the engagement between the latching portion 130 and the slot 320, or the latching portion 130 to affect the engagement between the first fixing portion 150 and the elastic member 120.

[0029] This application also provides a housing assembly, including the opening structure 100 provided in any of the above embodiments. In some embodiments, the body 300 is selected as the carrier, and the opening button 110 is rotatably disposed on the body 300.

[0030] In other embodiments, the upper cover 200 is selected as the carrier, and the opening key 110 is rotatably disposed on the upper cover 200. The elastic element 120 is connected between the opening key 110 and the upper cover 200, and the second end 122 of the elastic element 120 is connected to the upper cover 200.

[0031] The opening mechanism 100 is installed on the top cover 200. After the opening button 110 is rotated to release the lock between the top cover 200 and the body 300, the top cover 200 can be directly driven to rotate by the opening button 110 to open the top cover 200, simplifying the opening process of the top cover 200 and improving the convenience of operation.

[0032] In some preferred embodiments, the rotation direction of the cover release button 110 when switching from the locked position to the unlocked position is defined as the first rotation direction, which can be referred to as... Figure 5 As shown, Figure 5 In the diagram, the direction indicated by the dashed arrow is the first rotation direction. The rotation direction when the upper cover 200 separates from the body 300 is defined as the second rotation direction, which can be referenced. Figure 8 The direction indicated by the dashed arrow is the same for both the first and second rotation directions. This allows you to continue rotating the top cover 200 after turning the open button 110, further improving the ease of opening the cover.

[0033] In some preferred embodiments, the cover opening key 110 is fixed with a first fixing part 150, the carrier is fixed with a second fixing part 210, the first end 121 of the elastic member 120 is connected to the first fixing part 150, and the second end 122 of the elastic member 120 is connected to the second fixing part 210. (See reference...) Figure 3 As shown, Figure 3 In the diagram, the center position of the first fixing part 150 and the second fixing part 210 is indicated by the center position of the cross-dot line. Along the extension direction of the rotation axis of the cover opening key 110, the first fixing part 150 and the second fixing part 210 are offset from each other. The two are offset from each other in the rotation axis direction of the cover opening key 110. The elastic member 120 connected between the two is inclined relative to the rotation plane of the cover opening key 110, which further improves the damping effect between the rotating part 140 provided at the first end 121 of the elastic member 120 and the carrier, and increases the rotational resistance between the two.

[0034] Along the extension direction of the rotation axis of the cover opening key 110, the distance between the rotating part 140 near the first end 121 of the elastic member 120 and the first fixed part 150 is the first distance, and the distance between the rotating part 140 near the second end 122 of the elastic member 120 and the second fixed part 210 is the second distance. (Refer to...) Figure 3As shown, the first distance is denoted by L1, and the second distance is denoted by L2. In some embodiments, the second distance is smaller than the first distance. In other preferred embodiments, the second distance is smaller than the first distance, and in the extension direction of the rotation axis of the cover opening key 110, the second end 122 of the elastic member 120 is closer to the rotating part 140 adjacent to the elastic member 120, so that the cover opening key 110 as a whole tends to move closer to the rotating part 140, further increasing the rotational resistance between the rotating part 140 and the carrier.

[0035] The printer body 300 is the main component of the printer. The surface of the printer body 300 has a working space 310, which can be referenced. Figure 8 As shown, the working space 310 is used to install rollers, printing consumables, etc. In some embodiments, the carrier is the printer's upper cover 200, the cover opening button 110 is rotatably mounted on the upper cover 200, and the elastic element 120 and / or the first fixing part 150 are provided corresponding to the working space 310 on the surface of the body 300. When the upper cover 200 covers the body 300, the elastic element 120 and / or the first fixing part 150 are located in the working space 310, which can make full use of the working space 310, without the need to additionally provide a corresponding cavity on the surface of the body 300 to accommodate the elastic element 120 and / or the first fixing part 150.

[0036] In some embodiments, the workspace 310 includes a mounting space 311 for mounting a ribbon cartridge, and the elastic member 120 and / or the first fixing portion 150 are preferably disposed corresponding to the mounting space 311 on the surface of the housing 300. The mounting space 311 is part of the workspace 310, typically located at the edge of the workspace 310, and at the center of the edge, as can be seen from [reference]. Figure 8 and Figure 9 As shown, the elastic element 120 corresponds to the installation space 311, which limits the installation range of the opening structure 100 on the upper cover 200, so that the opening structure 100 is set as close as possible to the middle area of ​​the edge of the upper cover 200, making it easier to control the overall position of the upper cover 200 by controlling the opening key 110.

[0037] In some embodiments provided in this application, the second fixing part 210 includes a second connector 211 and a second reinforcing rib 212, see reference. Figure 6 and Figure 7 As shown, the second connector 211 is fixed to the carrier and connected to the second end 122 of the elastic member 120. The second reinforcing rib 212 is fixed between the second connector 211 and the carrier, thereby improving the connection stability between the second connector 211 and the carrier and improving the damage resistance of the second connector 211.

[0038] This application also provides a printer, including the housing assembly provided in any of the above embodiments. In some specific embodiments, please refer to... Figure 8As shown, in the housing assembly, the top cover 200 is selected as the carrier, with one side of the top cover 200 rotatably connected to the printer, and the opening structure 100 located on the other side of the top cover 200. In some other embodiments, the body 300 may also be selected as the carrier.

[0039] It should be noted that, in this document, the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
