Description

Technical Field

[0001] The utility model relates to the technical field of readers, and particularly relates to an e-reader. Background Art

[0002] In the design of existing e-readers, aluminum alloy is usually used as the main material for the middle frame. Aluminum alloy is widely used in electronic devices because of its good strength, corrosion resistance and processing performance. However, the density of aluminum alloy is relatively large. To ensure that the middle frame has sufficient structural rigidity, the existing design often adopts a relatively thick middle frame structure. Although this relatively thick design can enhance the compressive resistance and stability of the device, it also directly leads to a relatively large overall weight of the e-reader. For a device that needs to be held for a long time for operation, the heavy design is likely to cause hand fatigue, reduce the user's comfort, and is not conducive to improving the user's reading experience.

[0003] In order to improve this problem, in the prior art, attempts have been made to reduce the overall weight of the device by reducing the weight of the middle frame. For example, technicians usually adopt a hollow design, reduce the thickness of the middle frame, etc. to reduce the weight of the middle frame. However, although these designs reduce the weight of the device to a certain extent, when the thickness of the middle frame is reduced, the overall structural strength of the device also decreases accordingly, making the device prone to deformation or damage.

[0004] Therefore, an e-reader is proposed to solve the above problems. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an e-reader, aiming to solve the problem that the structural strength of the existing e-reader decreases when the weight of the middle frame is reduced.

[0006] To achieve the above utility model purpose, the utility model proposes an e-reader, which includes a housing provided with a groove, a middle frame fixed to the edge of the groove, and a display screen embedded in the middle frame. The characteristics are that the middle frame is made of magnesium alloy material, and a support member is arranged at the edge of the middle frame to enhance the structural strength of the middle frame.

[0007] Further, the support member includes a first support portion, the first support portion is arranged at the edge of the middle frame and faces the side of the display screen, and the side wall of the display screen corresponds to the inner wall of the first support portion.

[0008] Further, the support member further includes a plurality of groups of second support portions, the plurality of groups of second support portions are arranged on the side of the middle frame facing the housing, and the plurality of groups of second support portions enclose to form a first installation position and a second installation position.

[0009] Further, the second support portion is triangular in shape.

[0010] Furthermore, it further includes an antenna and a battery. The first mounting position is arranged near the edge of the middle frame, and the first mounting position is for mounting the antenna. The second mounting position is designed near the central area of the middle frame for mounting the battery.

[0011] Furthermore, the middle frame is provided with a plurality of through holes.

[0012] Beneficial effects:

[0013] An e-reader of the present utility model includes a housing provided with a groove, a middle frame fixed to the edge of the groove, and a display screen embedded in the middle frame. Among them, the middle frame is made of magnesium alloy material, and support members are arranged at the edge of the middle frame. These support members improve the compressive resistance and anti-deformation ability of the middle frame by dispersing the stress applied to the middle frame. The support members play a role of support and strengthening. At the same time, magnesium alloy is one of the structural materials with the lowest density among existing metal materials, about 2 / 3 of that of aluminum, and is lighter than traditional aluminum alloy. The design of the middle frame 200 using magnesium alloy material can significantly reduce the overall weight of the e-reader. Even if the middle frame is relatively thin, the device can still maintain good structural integrity during use and avoid deformation or damage caused by pressure or impact, achieving lightweight while ensuring structural strength.

[0034] Referring to Figures 1 to 6 , an embodiment of a utility model provides an e-reader, which includes a housing 100 provided with a groove 110, a middle frame 200 fixed to the edge of the groove 110, and a display screen 300 embedded in the middle frame 200. The characteristics are that the cross-sectional area of the middle frame 200 is much smaller than the cross-sectional areas of the housing 100 and the display screen 300, and support members are provided at the edge of the middle frame 200 to enhance the structural strength of the middle frame 200;

[0035] The middle frame 200 is made of magnesium alloy material;

[0036] The middle frame 200 is designed with a hollow structure.

[0037] In the embodiment of the present application, the design concept mainly focuses on achieving the lightweight of the device while ensuring the structural stability. In traditional e-readers, the middle frame 200 is usually relatively thick to improve the strength of the device. In this embodiment, the cross-sectional area of the middle frame 200 is much smaller than the cross-sectional areas of the housing 100 and the display screen 300. The middle frame 200 is designed to be ultra-thin, aiming to reduce the weight of the middle frame 200 and meet the lightweight standard of the e-reader; correspondingly, the ultra-thin design of the middle frame 200 also means that the thickness of the middle frame 200 itself is greatly reduced, thereby reducing the overall weight of the e-reader. To compensate for the possible strength deficiency caused by the reduction of the thickness of the middle frame 200, a plurality of support members are provided at the edge of the middle frame 200. These support members improve the compressive resistance and anti-deformation ability of the middle frame 200 by dispersing the stress applied on the middle frame 200. The support members play a role in supporting and strengthening, so that even if the middle frame 200 is relatively thin, the device can still maintain good structural integrity during use and avoid deformation or damage caused by pressure or impact, achieving lightweight while ensuring structural strength.

[0038] Furthermore, a plurality of through holes 800 are provided on the middle frame 200, making the middle frame 200 have a hollow design. The purpose of this design is to further reduce the weight of the middle frame 200.

[0039] In addition, the middle frame 200 is made of magnesium alloy. Magnesium alloy is one of the structural materials with the lowest density among existing metal materials, about 2 / 3 of that of aluminum, and is lighter than traditional aluminum alloy. The design of the middle frame 200 using magnesium alloy material can significantly reduce the overall weight of the e-reader. At the same time, although the density of magnesium alloy is low, it has a high strength-to-weight ratio (specific strength), which means that while reducing the weight, the magnesium alloy material can still provide sufficient structural strength to ensure that the middle frame 200 has compressive resistance and bending resistance.

[0040] In this embodiment, the processing method adopted is casting. The middle frame 200 is formed by casting with magnesium alloy. On the one hand, this is because magnesium alloy has better fluidity in the molten state. During the casting process, the liquid magnesium alloy can more easily fill complex die shapes and thin-wall areas. In contrast, the fluidity of aluminum alloy is lower, and incomplete filling may be more likely to occur when casting thin-wall parts. Moreover, magnesium alloy has a high cooling rate and the characteristic of rapid solidification, which helps to quickly form during the thin-wall casting process and reduces the risk of grain coarsening, thus enabling a more delicate thin-wall structure to be achieved. On the other hand, magnesium alloy has an excellent strength-to-weight ratio. Even when cast thinly, it can still maintain sufficient structural strength and rigidity. This means that while maintaining a lightweight design, the middle frame 200 can still withstand external pressure and impact, ensuring the structural integrity of the e-reader.

[0041] The support member includes a first support portion 400. The first support portion 400 is provided at the edge of the middle frame 200 and is arranged toward the side of the display screen 300. The side wall of the display screen 300 corresponds to the inner wall of the first support portion 400.

[0042] The support member further includes a plurality of groups of second support portions 500. The plurality of groups of second support portions 500 are provided on the side of the middle frame 200 facing the housing 100, and the plurality of groups of second support portions 500 enclose a first installation position 510 and a second installation position 520.

[0043] The second support portion 500 is triangular in shape.

[0044] The first support part 400 is arranged at the edge of the middle frame 200, designed around the edge of the middle frame 200, and is arranged on the side of the middle frame 200 facing the display screen 300. The display screen 300 is provided with an installation boss. When the display screen 300 is installed on the middle frame 200, the side wall of the installation boss abuts against the inner wall of the first support part 400, so that the front gap during the installation of the display screen 300 is extremely narrow, thus achieving a high degree of flatness. This design improves the appearance flatness of the e-reader. Users can feel the smoothness and flatness of the device surface during use, enhancing the visual and tactile experience of the device. At the same time, the force exerted by the display screen 300 is dispersed through the first support part 400, making the display screen 300 not easily displaced or loosened due to external forces, thereby enhancing the structural strength and shock resistance of the device.

[0045] On the side of the middle frame 200 extending towards the housing 100, a plurality of groups of second support parts 500 are arranged. The plurality of groups of second support parts 500 enclose a first installation position 510 and a second installation position 520 on the middle frame 200 for installing the antenna 600 and the battery 700. In addition, the second support part 500 is in the shape of a right triangle. This design is because the support part in the shape of a right triangle can enhance the overall strength of the middle frame 200, reduce deformation or damage caused by stress concentration, thereby increasing the durability of the device. At the same time, the design of the right triangle can reduce the amount of material used while ensuring the support strength, thus achieving the effect of light weight.

[0046] The e-reader further includes an antenna 600 and a battery 700. The first installation position 510 is arranged close to the edge of the middle frame 200 and is used for installing the antenna 600. The second installation position 520 is designed close to the central area of the middle frame 200 and is used for installing the battery 700.

[0047] The first installation position 510 is close to the edge of the middle frame 200 and is used for installing the antenna 600. The antenna 600 is located at the top of the device to maximize the signal reception efficiency. The second installation position 520 is close to the central area of the middle frame 200 and is used for accommodating and fixing the battery 700. This design makes the battery 700 located at the center of gravity of the device, which helps to balance the weight distribution of the entire e-reader and ensure the stability of the device and the comfort during holding.

[0048] This solution adopts a 50:50 weight distribution design. In this solution, the volume of the battery 700 is reduced and it is arranged in the central area of the middle frame 200, thereby ensuring that the center of gravity of the device is concentrated, improving the balance and comfort of holding the device. In addition, the antenna 600 is arranged at the upper end of the e-reader, and the circuit board is located at the lower end of the middle frame 200. The circuit board is electrically connected to the antenna 600.

[0049] Specifically, the antenna 600 is designed to be located near the edge of the middle frame 200, which can ensure the best signal transmission and reception effects, contribute to improving the signal reception efficiency. The battery 700 is located at the center of the middle frame 200, and the circuit board is located at the lower end of the middle frame 200. Such an arrangement helps to maintain the center of gravity balance of the device and enhance the handheld experience of the device. In addition, the installation position of the battery 700 is close to the central area of the middle frame 200. This design can effectively disperse the weight of the e-reader, making the device more balanced when held by hand.

[0050] The core of the 50:50 weight balance design in this embodiment lies in optimizing the weight distribution of the e-reader to improve the balance of the device and the comfort of the user when holding it. By setting the antenna 600 on the top of the middle frame 200, the battery 700 in the central area of the middle frame 200, and the circuit board at the lower end of the device, it not only ensures the reasonable layout of the internal functional components of the device but also achieves the balanced distribution of weight in the longitudinal direction. The principle of the 50:50 weight balance design is to shrink the battery 700 and place it at the center of the middle frame 200, set the antenna 600 on the top of the device, and the circuit board at the bottom, so that the entire e-reader maintains longitudinal balance during use. The antenna 600 and the circuit board are located at both ends of the device respectively, playing a role in balancing the weight of the device components. As one of the heaviest components in the device, the battery 700 is placed at the center of the device, which helps to avoid the weight shifting to one end, making the center of gravity of the device located in the central area of the handheld device. In this way, when the user is using it, the device can remain stable in various holding postures, making the reading experience more natural and smooth.

[0051] Refer to Figure 6 , when the middle frame 200 is installed on the housing 100, both sides in the length direction of the housing 100 bend towards the middle frame 200. The hypotenuse of the second support portion 500 extending towards the housing 100 side on the middle frame 200 is parallel to the inner wall of the bent portion of the housing 100, as Figure 6 indicated by the arrow. The purpose of such an arrangement is to reduce the weight of the reader as much as possible to achieve the effect of light weight.

[0052] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
