[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model 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 utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 utility model.

[0024] In this utility model, unless otherwise explicitly 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 explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through 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. "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.

[0026] In today's era of widespread mobile internet technology, electronic devices such as tablets, unlike laptops, play a crucial role in personal applications, allowing people to stay connected with the world at all times. However, because the interaction methods of electronic devices rely heavily on touchscreens, their interaction efficiency is low in many usage scenarios. Furthermore, the need to hold the device during prolonged use or screen viewing negatively impacts the user experience. Therefore, 2-in-1 electronic devices have emerged, designed as accessories that combine the functions of an electronic device and a support device, providing both a more efficient input method and support. However, as users have increasingly higher demands for the appearance and weight of portable 2-in-1 electronic devices and accessory kits, complex designs lead to increased product costs, weight, and reduced aesthetics. On the other hand, overly simple support accessories often only allow the tablet to open at a fixed angle, affecting the user experience. For example, currently, tablet accessories on the market are basically of two types: one uses the tablet's own magnets to magnetically attach the accessory, and the other uses a protective case that tightly fits the tablet and then magnetically attaches the accessory. The limitation of the magnetic attachment structure is that the fit between the tablet and the accessory is not secure and the clamping force is insufficient.

[0027] refer to Figures 1-5 To address the aforementioned issues, this application provides a clamping and fixing base 40, comprising a base 41, a clamping sleeve 42, and a rotating shaft assembly 43. The clamping sleeve 42 includes a rigid bracket 421 and a snap-fit ​​sleeve 422. The rigid bracket 421 includes an adapter 4214 and a first fixing plate 4211, a second fixing plate 4212, and a third fixing plate 4213 connected in sequence. The first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213 together form a first U-shaped fitting groove 44. The snap-fit ​​sleeve 422 is fixed in the first U-shaped positioning groove 44, and a second U-shaped positioning groove 45 with the same opening direction as the first U-shaped positioning groove 44 is formed in the snap-fit ​​sleeve 422. The adapter 4214 is fixed on at least one of the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213. The adapter 4214 and the base 41 are rotatably connected through the rotating shaft assembly 43. The base 41 is used to fix the electronic device accessory 30, and the snap-fit ​​sleeve 422 is used to clamp the electronic device 20.

[0028] See Figures 1-4The clamping and fixing base 40 includes a base 41, a clamping sleeve 42, and a rotating shaft assembly 43. The clamping and fixing base 40 can clamp the electronic device 20, and the electronic device accessory 30 is fixed to the base 41. The rotating shaft assembly 43 enables a rotatable connection between the adapter 4214 and the base 41. The electronic device accessory 30 can be a handwriting tablet, electronic device accessory, game operating device, HUB, etc., and the electronic device 20 can be a computer, monitor, iPad, etc. The electronic device accessory 30 and the electronic device 20 can form a system of input device and display device. The clamping sleeve 42 includes a rigid bracket 421 and a snap-fit ​​sleeve 422. The rigid bracket 421 includes a first fixing plate 4211, a second fixing plate 4212 and a third fixing plate 4213 connected in sequence. The first fixing plate 4211, the second fixing plate 4212 and the third fixing plate 4213 can together form a first U-shaped fitting groove 44. In some embodiments, the first fixing plate 4211, the second fixing plate 4212 and the third fixing plate 4213 can be an integrally formed structure. The first fixing plate 4211, the second fixing plate 4212 and the third fixing plate 4213 can be made of aluminum alloy. The snap-fit ​​sleeve 422 has a second U-shaped groove 45, the opening direction of which is the same as that of the first U-shaped groove 44. This same opening direction facilitates the placement of the snap-fit ​​sleeve 422 inside the first U-shaped groove 44. The snap-fit ​​sleeve 422, placed inside the first U-shaped groove 44, acts as a buffer. When the snap-fit ​​sleeve 422 contacts the electronic device 20, the elastic force generated by the snap-fit ​​sleeve 422, through the structure of the rigid bracket 421 and the snap-fit ​​sleeve 422 cooperating with each other, clamps tightly against the edge of the electronic device 20, increasing the bonding strength without increasing the overall thickness of the electronic device 20. Specifically, the snap-fit ​​sleeve 422 can be a flexible or elastic sleeve with protective functions. When an elastic sleeve is used as the snap-fit ​​sleeve 422, it not only provides protection but also a reaction force, thus providing both protection and a certain clamping effect. For example, the snap-fit ​​sleeve 422 can be made of silicone. The silicone snap-fit ​​sleeve 422 has high tensile strength and can withstand large tensile forces. At the same time, the silicone snap-fit ​​sleeve 422 has good wear resistance and can maintain its shape and function during frequent use, thereby improving the service life of the clamping fixture 40. Since the snap-fit ​​sleeve 422 is used to clamp the electronic device 20, the snap-fit ​​sleeve 422 made of silicone has a softer texture and can better protect the surface of the electronic device 20, thereby avoiding scratches on the surface of the electronic device 20 during installation and improving the user experience.

[0029] See Figures 1-4In some embodiments, the rigid bracket 421 includes an adapter 4214, which can be fixed to a first fixing plate 4211 or a second fixing plate 4212. In other embodiments, the adapter 4214 can also be fixed to a third fixing plate 4213. The adapter 4214 is rotatably connected to the base 41 via a rotating shaft assembly 43. The base 41 is fixedly connected to the electronic device accessory 30. Due to the rotatable connection between the adapter 4214 and the base 41, the adapter 4214 is connected to the electronic device... The accessories 30 are rotatably connected, and the rigid bracket 421 and the snap-fit ​​sleeve 422 move in the same way. The snap-fit ​​sleeve 422 clamps the electronic device 20. Therefore, the above structural features work together to enable the adjustment of the angle between the electronic device accessory 30 and the electronic device 20 when the electronic device 20 is clamped by the clamping and fixing seat 40. This allows the electronic device accessory 30 to be connected to the electronic device 20 without increasing the thickness of the flat plate. At the same time, the angle between the electronic device 20 and the electronic device accessory 30 can be adjusted according to the user's needs.

[0030] See Figures 2-5 In some embodiments, the snap-fit ​​sleeve 422 forms a first U-shaped protrusion 4221 and a second U-shaped protrusion 4222 spaced apart on the side opposite to the second U-shaped mounting groove 45. The first U-shaped protrusion 4221 and the second U-shaped protrusion 4222 serve to clamp the rigid bracket 421. Specifically, the first U-shaped protrusion 4221 and the second U-shaped protrusion 4222 both extend along the connection direction of the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213, and the first U-shaped protrusion 4221 and the second U-shaped protrusion 4222 can be respectively provided at the ends. In some embodiments, a mounting groove 46 is formed between the first U-shaped protrusion 4221 and the second U-shaped protrusion 4222, and the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213 are located in the mounting groove 46 and are clamped by the first U-shaped protrusion 4221 and the second U-shaped protrusion 4222. The first U-shaped protrusion 4221 wraps around the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213 at one end of the third direction P3, and the second U-shaped protrusion 4222 wraps around the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213 at the other end of the third direction P3. The first U-shaped protrusion 4221 and the second U-shaped protrusion 4222 clamp the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213, which is conducive to the tight assembly between the rigid bracket 421 and the snap-fit ​​sleeve 422, and at the same time, it is conducive to fixing the position of the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213.

[0031] See Figure 2 , Figure 3 and Figure 4In some embodiments, the first fixing plate 4211 and the third fixing plate 4213 extend relative to the second fixing plate 4212 along the first direction P1, and the first fixing plate 4211 and the third fixing plate 4213 are spaced apart relative to each other along the second direction P2. The first fixing plate 4211, the second fixing plate 4212 and the third fixing plate 4213 can together form a U-shaped structure. In some embodiments, the first fixing plate 4211, the second fixing plate 4212 and the third fixing plate 4213 are integrally formed structures, which is beneficial to improving the ease of assembly of the clamping fixing seat 40. The first U-shaped positioning groove 44 passes through the opposite sides of the rigid bracket 421 along the third direction P3. The first direction P1 is perpendicular to the second direction P2, the second direction P2 is perpendicular to the third direction P3, and the first direction P1 is perpendicular to the third direction P3.

[0032] Continue reading Figure 2 , Figure 3 and Figure 4 In some embodiments, the second U-shaped mounting groove 45 passes through the opposite sides of the snap-fit ​​sleeve 422 along the third direction P3. When the clamping sleeve 42 is installed on the edge of the electronic device 20, the electronic device 20 can pass through the clamping sleeve 42. At the same time, the snap-fit ​​sleeve 422 can be easily removed from the rigid bracket 421 for replacement, so that a matching snap-fit ​​sleeve 422 can be replaced according to the different thicknesses of the electronic device 20. In some embodiments, the snap-fit ​​sleeve 422 respectively wraps around the ends of the first fixing plate 4211 and the third fixing plate 4213 away from the second fixing plate 4212. The snap-fit ​​sleeve 422 is located at the ends of the first fixing plate 4211 and the third fixing plate 4213, which can reduce the volume of the snap-fit ​​sleeve 422. While ensuring the clamping effect of the snap-fit ​​sleeve 422, it can reduce the cost of the clamping fixing base 40. At the same time, the size of the snap-fit ​​sleeve 422 can be replaced according to the user's needs. For example, the snap-fit ​​sleeve 422 of different thicknesses can be replaced with snap-fit ​​sleeves of different thicknesses to match the thickness of the display device 10, so that the snap-fit ​​sleeve 422 can be stably clamped on the electronic device 20.

[0033] See Figure 2 , Figure 3 and Figure 4In some embodiments, the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213 are exposed on the side opposite to the first U-shaped mounting groove 44 in the snap-fit ​​sleeve 422, so that the outer side of the clamping fixing seat 40 is the first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213. The first fixing plate 4211, the second fixing plate 4212, and the third fixing plate 4213 can be made of aluminum alloy. Aluminum alloy has the advantages of high strength, lightweight, and corrosion resistance. The rigid bracket 421 of aluminum alloy facing outward can withstand a large external force, ensuring the stable clamping support of the clamping fixing seat 40, so as to realize the function of the clamping fixing seat 40 to stably fix the electronic device 20. At the same time, it is suitable for different usage environments and can extend the service life of the clamping fixing seat 40. When the clamping and fixing base 40 is located at the end of the electronic device 20, the end is prone to friction. The first fixing plate 4211, the second fixing plate 4212 and the third fixing plate 4213 made of aluminum alloy can reduce the friction at the end of the electronic device 20 to a certain extent, which is beneficial to reduce the friction and collision at the end of the electronic device 20.

[0034] See Figures 1-4 In some embodiments, the rotating assembly includes a rotating shaft 431 and a mounting plate 432. The rotating shaft 431 is rotatably connected to the mounting plate 432, and the rotating shaft 431 is interference-fitted to the adapter 4214, enabling a stable connection between the rotating shaft 431 and the adapter 4214. The mounting plate 432 is fixed to the base 41, which is used to fix the electronic device accessory 30, enabling a rotatable connection between the rotating shaft 431 and the fixed electronic device accessory 30, facilitating angle adjustment between the fixed electronic device accessory 30 and the electronic device 20 during use. In some embodiments, the second fixing plate 4212 has a support frame 47 on the side opposite to the first U-shaped mounting groove 44. When the rigid support 421 rotates relative to the base 41 so that the second U-shaped mounting groove 45 faces upward toward the base 41, the support frame 47 faces downward toward the base 41 to support the rigid support 421. After the electronic device 20 is installed, the support frame 47 can be supported on a tabletop, preventing the clamping fixing seat 40 from rotating due to the excessive weight of the electronic device 20, thereby improving the usability of the clamping fixing seat 40.

[0035] See Figure 1The display device 10 of the second aspect of this utility model includes an electronic device accessory 30, an electronic device 20, and a clamping and fixing base 40 of the first aspect embodiment. The electronic device accessory 30 is fixed to the base 41, and the electronic device 20 is clamped in the second U-shaped mounting groove 45. The electronic device 20 can be a tablet computer. The display device 10 enables the snap-fit ​​sleeve 422 to be easily detached and replaced from the rigid bracket 421, thereby allowing for the replacement of matching snap-fit ​​sleeves 422 according to the different thicknesses of the electronic devices 20. Since this embodiment adopts all the technical features of the clamping and fixing base 40 of the first aspect embodiment, this embodiment possesses all the beneficial effects brought by the first aspect embodiment, which will not be repeated here.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
