Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a buffer mechanism of a printer. Background Art

[0002] The patent document (CN221272335U) discloses in the description that "existing printers on the market usually have the function of opening and closing the upper cover by rotating the upper cover relative to the lower cover, but when the upper cover is opened or closed, the upper cover and the lower cover will collide; or, the upper cover is easy to fall and hit the lower cover after opening. In order to reduce the collision between the upper cover and the lower cover when they reach the maximum opening or are closed, and to increase the stability of the upper cover when opening and closing, a damper is usually provided at the hinge of the upper cover and the lower cover. The damper has a buffering effect on the opening and closing of the upper cover. However, to provide the damper, it is necessary to reserve installation space for the damper at the hinge of the upper cover and the lower cover, and the structure is complex and the number of parts increases, which makes the structural space requirement, structural cost and assembly cost of the printer high."

[0003] Therefore, in the prior art, providing a damper will increase the structural space requirement, structural cost, and assembly cost of the printer. Although providing a damper will enhance the buffering force, it will also affect the opening time of the upper cover. Utility Model Content

[0004] In order to solve one or more problems in the prior art, the present utility model provides a buffer mechanism for a printer.

[0005] The technical solution of the utility model is as follows: A buffer mechanism of a printer, comprising: a printer body, a rear cover, a first buffer portion, a second buffer portion, and a third buffer portion, wherein one side of the rear cover is hinged to the printer body, the first buffer portion is arranged on the printer body, and the second buffer portion and the third buffer portion are respectively arranged on the rear cover;

[0006] When the rear cover is opened, the first buffer portion contacts the inclined surface of the second buffer portion and slides along the inclined surface to the end of the second buffer portion. When the first buffer portion reaches the end of the second buffer portion, the third buffer portion abuts against the printer body.

[0007] According to the above technical solution, in the buffer mechanism of the printer, at least one set of clamping feet is provided on the rear cover, and the second buffer portion and the third buffer portion are respectively provided on the clamping feet.

[0008] By adopting the above-mentioned technical solutions, in the buffer mechanism of the printer, the second buffer portion includes a slope structure and a groove structure, the slope structure is arranged on the side of the clamping foot close to the third buffer portion, and the groove structure is arranged on the side of the clamping foot away from the third buffer portion.

[0009] By adopting the above technical solutions, the buffer mechanism of the printer further includes a tension spring member, an installation assembly is provided on the clamping foot member, and the tension spring member is provided on the installation assembly; when the rear cover is opened, the tension spring member is used to provide elastic force to cause the rear cover to be bounced open.

[0010] By adopting the above-mentioned technical solutions, in the buffer mechanism of the printer, the installation component includes a fixed block and a limiting groove respectively arranged on the clamping foot member, the tension spring member is arranged on the fixed block, the first end of the tension spring member is connected to the limiting groove, and the second end of the tension spring member is connected to the printer body.

[0011] With the above technical solutions, in the buffer mechanism of the printer, a middle frame is provided in the printer body, a mounting hole is provided on the middle frame, and the second end of the tension spring is connected to the mounting hole.

[0012] By adopting the above technical solutions, in the buffer mechanism of the printer, the angle between the inclined surface structure and the rear cover is 75°.

[0013] With the above technical solutions, in the buffer mechanism of the printer, the first buffer portion includes a buffer ball disposed in the printer body.

[0014] With the above technical solutions, in the buffer mechanism of the printer, the third buffer portion includes a buffer block provided on the clamping foot.

[0015] With the above technical solutions, in the buffer mechanism of the printer, an angle is set between the buffer block and the foot member. When the buffer block contacts the printer body, the buffer block squeezes toward the foot member to provide buffering.

[0016] The first, second, and third buffers employed in this utility model eliminate the need for additional dampers, saving space, making the printer more compact, and reducing manufacturing and assembly costs. Furthermore, the first, second, and third buffers do not affect the opening speed of the rear cover, allowing the user to quickly open the printer.

[0025] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, or indirect connections through an intermediate medium; they may refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] In the present utility model, it should also be noted that the directional terms such as one side, one end, the other end, top and bottom in the embodiments of the present application are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0028] like Figures 1 to 3As shown, an embodiment of the present application provides a buffer mechanism of a printer, comprising a printer body 1, a rear cover 2, a first buffer portion 3, a second buffer portion 4 and a third buffer portion 5. One side of the rear cover 2 is hinged to the printer body 1, the first buffer portion 3 is arranged on the printer body 1, and the second buffer portion 4 and the third buffer portion 5 are respectively arranged on the rear cover 2; when the rear cover 2 is opened, the first buffer portion 3 contacts the inclined surface of the second buffer portion 4 and slides along the inclined surface to the end of the second buffer portion 4. When the first buffer portion 3 reaches the end of the second buffer portion 4, the third buffer portion 5 abuts against the printer body 1.

[0029] In this embodiment, the printer body 1 is the main body of the printer, and the rear cover 2 is a cover that protects the printer's internal components. The two are connected by a hinge and can be opened and closed. This allows for easy opening and closing of the printer, making it convenient for users to change paper or perform maintenance. Three buffers are located on the printer body 1 and rear cover 2, respectively, to mitigate the impact of the rear cover 2 against the printer body 1 during opening, thereby reducing noise and protecting the printer. This improves smooth opening, reduces noise, and extends the life of the printer. The first buffer 3 and second buffer 4 are located on the printer body 1 and rear cover 2, respectively, forming an inclined surface between them. When the rear cover 2 is opened, the first buffer 3 contacts the inclined surface of the second buffer 4, forming a primary buffer. The first buffer 3 then slides along the inclined surface and contacts the second buffer 4, slowing the impact and creating a secondary buffer. This primary buffer reduces the impact force and noise. When the first buffer 3 slides to the end of the second buffer 4, the third buffer 5 contacts the printer body 1, forming a tertiary buffer. This tertiary buffer further reduces the impact force and noise. Specifically, the first, second, and third buffers 3, 4, and 5 employed in this solution eliminate the need for additional dampers, saving space, making the printer more compact, and reducing manufacturing and assembly costs. Furthermore, the first, second, and third buffers 3, 4, and 5 do not affect the opening speed of the rear cover 2, allowing the user to quickly open the printer. By employing a sliding bevel and abutting buffer components, effective damping can be achieved without the need for dampers, while maintaining structural compactness and opening speed. This addresses the shortcomings of existing technologies and provides users with a more convenient and comfortable printing experience.

[0030] like Figure 1As shown, the rear cover 2 is further provided with at least one set of latching members 20, with the second and third buffering portions 4 and 5 respectively disposed on the latching members 20. In this embodiment, the latching members 20 are fixed to the rear cover 2, providing support and positioning for the second and third buffering portions 4 and 5. This enhances the stability and durability of the buffering components and ensures accurate buffering. When the rear cover 2 begins to open, the inclined surface of the second buffering portion 4 contacts the first buffering portion 3 of the printer body 1, forming a primary buffer. This primary buffer effectively mitigates the initial impact force when the rear cover 2 opens, reducing noise. As the rear cover 2 continues to open, the first buffering portion 3 slides along the inclined surface of the second buffering portion 4, forming a secondary buffer. This secondary buffer further slows the impact velocity through the inclined sliding surface, enhancing the buffering effect and reducing noise and impact. When the rear cover 2 is fully opened, the third buffering portion 5 contacts the printer body 1, forming a tertiary buffer. This tertiary buffer ensures that the rear cover 2 does not collide with the printer body 1 when fully opened, thereby minimizing noise and potential mechanical damage.

[0031] like Figure 4 As shown, the second buffering portion 4 further includes a sloped surface structure 40 and a groove structure 41. The sloped surface structure 40 is disposed on the side of the clamping member 20 near the third buffering portion 5, while the groove structure 41 is disposed on the side of the clamping member 20 away from the third buffering portion 5. In this embodiment, the sloped surface structure 40 of the second buffering portion 4 is disposed on the clamping member 20 near the third buffering portion 5. When the rear cover 2 is opened, the first buffering portion 3 of the printer body 1 contacts the sloped surface structure 40, thereby initiating the buffering process. The sloped surface structure 40 effectively mitigates the impact of opening the rear cover 2, providing a primary buffering effect and reducing noise and vibration. The groove structure 41 is disposed on the side of the clamping member 20 away from the third buffering portion 5. After the sloped surface structure 40 completes the initial buffering, the first buffering portion 3 may continue to slide into the groove structure 41 for further buffering. The groove structure 41 provides additional buffering space, making the buffering process smoother, further reducing noise and vibration, and protecting the printer's internal components from impact.

[0032] like Figure 1As shown, it further includes a tension spring member 6, and a mounting assembly is provided on the clamping foot member 20, and the tension spring member 6 is provided on the mounting assembly; when the back cover 2 is opened, the tension spring member 6 is used to provide elastic force to make the back cover 2 pop open. In this embodiment, the tension spring member 6 is an elastic element, which is provided on the mounting assembly. When the back cover 2 is closed, the tension spring member 6 is compressed to store energy; when the back cover 2 is opened, the tension spring member 6 releases energy and provides elastic force. The tension spring member 6 provides sufficient elastic force to help the user easily open the back cover 2, while ensuring that the back cover 2 maintains a certain speed and stability during the opening process. The mounting assembly is fixed on the clamping foot member 20, and is used to install and fix the tension spring member 6, ensuring that the tension spring member 6 works in the correct position and direction. The mounting assembly enables the tension spring member 6 to effectively cooperate with the clamping foot member 20 and the back cover 2.

[0033] like Figure 3 As shown, the mounting assembly further includes a fixing block 21 and a limiting slot 22, respectively disposed on the clamping foot 20. The tension spring 6 is disposed on the fixing block 21, with a first end of the tension spring 6 connected to the limiting slot 22, and a second end of the tension spring 6 connected to the printer body 1. In this embodiment, the fixing block 21 is disposed on the clamping foot 20 to secure one end of the tension spring 6, ensuring that the tension spring 6 is correctly positioned. The fixing block 21 provides a stable support point, enabling the tension spring 6 to effectively provide elastic force while preventing displacement during printer use. The limiting slot 22 is disposed on the clamping foot 20 to connect to the first end of the tension spring 6. The design of the limiting slot 22 limits the range of movement of the tension spring 6, maintaining its stability. The limiting slot 22 ensures that the direction and strength of the elastic force provided by the tension spring 6 are precisely controlled, thereby improving the reliability and safety of the buffer mechanism. The first end of the tension spring 6 is secured in the retaining slot 22. When the rear cover 2 is closed, the tension spring 6 is compressed, storing energy. This connection allows the tension spring 6 to release this stored energy when the rear cover 2 is opened, providing a uniform spring force and helping the user easily open the rear cover 2. The second end of the tension spring 6 is connected to the printer body 1. When the rear cover 2 is opened, the tension spring 6 extends to provide a spring force. This connection ensures that the tension spring 6 functions effectively when opening the rear cover 2, while maintaining a stable opening and preventing damage from rapid opening.

[0034] like Figure 2As shown, further, a middle frame 10 is provided within the printer body 1, and a mounting hole 11 is provided on the middle frame 10. The second end of the tension spring member 6 is connected to the mounting hole 11. In this embodiment, the middle frame 10 is the skeleton structure inside the printer, used to support and fix the various components inside the printer. The middle frame 10 provides a stable structural foundation, ensuring the overall strength of the printer and the positioning accuracy of the internal components. The mounting hole 11 is provided on the middle frame 10 for installing and fixing the second end of the tension spring member 6. The mounting hole 11 provides an accurate installation position for the tension spring member 6, ensuring that the tension spring member 6 can function in the correct position.

[0035] like Figure 4 As shown, further, the angle between the inclined surface structure 40 and the rear cover 2 is 75°. The inclined surface structure 40 is arranged on the second buffer portion 4, and forms an inclined surface at a certain angle with the rear cover 2. When the rear cover 2 is opened, this inclined surface structure 40 contacts the first buffer portion 3 of the printer body 1 and slides along the inclined surface, thereby gradually releasing energy to achieve a buffering effect. The specific setting of the angle of 75° is to optimize the buffering force and the smoothness of the cover opening process. The angle of 75° can provide appropriate buffering force, which is neither too strong to hinder the opening of the cover, nor too weak to achieve a poor buffering effect.

[0036] like Figure 3 As shown, the first buffer portion 3 further includes a buffer ball disposed within the printer body 1. The buffer ball is an elastic element disposed within the printer body 1 and contacts the inclined surface structure 40 of the second buffer portion 4. When the rear cover 2 is opened, the first buffer portion 3 of the printer body 1 contacts the inclined surface structure 40 of the second buffer portion 4, and the buffer ball begins to provide elastic force, slowing the opening of the rear cover 2.

[0037] like Figure 5 and Figure 6 As shown, when the rear cover 2 is opened to 60° from the printer body 1, the first buffer portion 3 is on the inclined structure 40 of the second buffer portion 4; when the rear cover 2 is opened to 90°, the first buffer portion 3 is on the groove structure 41 of the second buffer portion 4.

[0038] like Figure 3As shown, the third buffer portion 5 further includes a buffer block disposed on the clamping member 20; an angle is formed between the buffer block and the clamping member 20. When the buffer block contacts the printer body 1, the buffer block squeezes toward the clamping member 20 to provide a buffer. The buffer block is an elastic element, disposed on the clamping member 20, and is used to provide a final buffer when contacting the printer body 1. The buffer block absorbs the remaining impact force, ensuring that the rear cover 2 does not collide with the printer body 1 when fully opened, thereby reducing noise and potential mechanical damage. The angle between the buffer block and the clamping member 20 allows the buffer block to squeeze toward the clamping member 20 when contacting the printer body 1, thereby forming a dynamic buffer zone. This angle design allows the buffer block to more effectively absorb impact force, forming a more stable buffer zone, improving the buffering effect, and protecting the internal components of the printer from impact.

[0039] By adopting the above-mentioned technical solutions, the first, second, and third buffers 3, 4, and 5 employed in the present invention eliminate the need for additional dampers, saving space, making the printer more compact, and reducing the printer's manufacturing and assembly costs. Furthermore, the first, second, and third buffers 3, 4, and 5 do not affect the opening speed of the rear cover 2, allowing the user to quickly open the printer. By employing an inclined sliding surface and abutting buffer components, an effective buffering effect is achieved without the need for dampers, while maintaining structural compactness and opening speed. This addresses the shortcomings of existing technologies and provides users with a more convenient and comfortable printing experience.
