Description

Technical Field

[0001] The utility model belongs to the technical field of display equipment, in particular to an electronic ink screen device and a frame component. Background Art

[0002] An electronic ink screen is a screen that uses electronic ink. Like paper, it is a "reflective" reading medium that mainly uses the reflection of ambient light to allow users to see the content on the screen clearly, so there is no problem of eye damage. It consumes power only when the pixel color changes, that is, the black and white color conversion on the screen is short. The image on the screen is still retained after the power is turned off, so it has excellent energy consumption performance during use.

[0003] Electronic ink screens are now mainly used in the field of e-books, and their use in billboards, signboards, product labels and other fields has gradually become widespread. Due to their unique visual and energy consumption advantages, it can be foreseen that electronic ink screens will be more and more widely used in the future. In the prior art, in order to make full use of public transportation scenarios, advertisements are placed on the handles of public transportation. In order to facilitate switching between different advertisements, some handles also use electronic ink screens. However, in the existing handles, the electronic ink screen is designed as an integrated part of the handle. Once the electronic ink screen is damaged and needs to be repaired, the entire handle needs to be replaced, which makes it difficult to replace and repair the electronic ink screen.

[0004] The patent with the authorization announcement number CN210337679U discloses a public transportation vehicle handle using an electronic ink screen, which uses an electronic display of advertising content to display multiple advertisements in the same period, greatly reducing marginal costs. The setting of the operation button enables interactive operation between the device and the advertising receptor, optimizes the experience, and improves the effect of advertising. However, in this solution, the electronic ink screen and the handle are an integrated design. Once the electronic ink screen is damaged, the entire handle needs to be removed for repair, which is not conducive to later maintenance. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] Please refer to Figures 1 to 7A frame component can be used to set an electronic ink screen 6 and other advertising devices. This embodiment describes the various structures in the case of setting the electronic ink screen 6. It should be understood that this frame component is not only applicable to the electronic ink screen 6, but also to other advertising devices. The frame assembly includes a pull ring 1, a stainless steel frame 2, a first connecting member 3 and a second connecting member 4, wherein the upper and lower sides of the stainless steel frame 2 are respectively connected to the first connecting member 3 and the pull ring 1; one side of the second connecting member 4 is connected to the first connecting member 3, and the opposite side is fixedly connected to the mounting cross bar 5; it also includes a mounting bracket 7 for mounting an electronic ink screen 6, wherein the mounting bracket 7 is detachably connected to the stainless steel frame 2 through two quick-release parts 8 on the left and right sides, wherein the quick-release parts 8 include a through hole 81 symmetrically arranged on the stainless steel frame 2 and a countersunk hole 82 arranged on the mounting bracket 7, a slider 811 in the through hole having the same length as the hole depth, a base 822 at the bottom of the countersunk hole, and a limit block 821 elastically connected to the bottom of the hole, wherein the sum of the axial lengths of the limit block 821 and the base 822 is equal to the hole depth of the countersunk hole 82; two mounting frames 71 for mounting the electronic ink screen 6 are symmetrically arranged in the mounting bracket 7, and the frame surface is downward at an angle of 5 to 15 degrees to the vertical direction. Specifically, the stop block 821 and the countersunk hole 82 are respectively fixedly connected with the two ends of a spring. When there is no external force, the spring will make the stop block 821 extend out of the countersunk hole 82 and get stuck between the through hole 81 and the countersunk hole 82, playing a limiting role. When the slider 811 is pressed, the stop block 821 is compressed to the bottom of the hole, and finally close to the base 822, so that the top surface of the stop block 821 is parallel to the top surface of the countersunk hole 82. At the same time, the surface of the slider 811 near the stop block 821 is parallel to the surface of the through hole 81 near the countersunk hole 82. At the same time, the four sliders 811 set on the stainless steel frame 2 are pressed to remove the entire mounting bracket 7. When installing, you only need to press the stop blocks 821 on the four mounting brackets 7, embed the mounting bracket 7 into the stainless steel frame 2, and when it is adjusted to a suitable position, the stop block 821 extends out under the elastic force of the spring and gets stuck between the through hole 81 and the countersunk hole 82, and the installation is completed. Preferably, the through hole 81 and the counterbore 82 are both rectangular holes, and the slider 811 and the limit block 821 are both cuboids corresponding to the rectangular holes. Further, the through hole 81 and the counterbore 82 can be hexagonal holes, and the slider 811 and the limit block 821 are both strip blocks with hexagonal cross-sections corresponding to the hexagonal holes.

[0030] By setting a quick-release part, the mounting bracket with the electronic ink screen can be quickly disassembled and assembled. In actual application, it can be quickly installed during production and manufacturing, which is conducive to saving man-hours. When the electronic ink screen is damaged, it can also be replaced by quickly replacing the mounting bracket separately, so that the remaining undamaged parts can continue to be used, which is conducive to reducing the time cost and economic cost of later maintenance. In actual application scenarios, the advertising area of ​​the public transportation handle is higher than the heads of most standing users and sitting users. There is a large inclination angle between the user's line of sight and the advertising plane, so that the user is not located in the best viewing area, which will cause problems such as unclear pictures and glare, and have a greater adverse effect on the advertising effect. In this embodiment, the frame surface of the mounting frame 71 is set to be 5 to 15 degrees downward with the vertical direction. The angle between the user's line of sight and the advertising plane is close to 90 degrees, which solves the problem that the user is not in the best viewing area, effectively improves the user's viewing experience, and improves the user's enthusiasm for watching advertisements, and finally achieves the technical goal of enhancing the advertising effect. It can be understood that the mounting crossbar 5 is a crossbar used to install the handle on ordinary public transportation. Preferably, the mounting crossbar 5 is a handle mounting crossbar on a bus or a handle crossbar on a subway. Preferably, the angle between the frame surface of the mounting bracket 7 and the vertical direction is set to 5 degrees, 10 degrees or 15 degrees.

[0031] An annular optimization portion 72 is fixedly provided outside the installation frame 71, and the optimization portion 72 is a black translucent acrylic plate. Limited by the current ink screen technology, the device equipped with the ink screen 6 cannot achieve a high screen-to-body ratio similar to that of a mobile phone or a tablet computer, which will make the device have a larger border, and the user cannot visually obtain the visual experience of a "high screen-to-body ratio". In this embodiment, the annular optimization portion 72 covers the surrounding surface of the electronic ink screen 6 after the electronic ink screen 6 is installed, and serves as the border of the electronic ink screen 6, achieving a visual effect of a higher screen-to-body ratio. The acrylic plate is light in weight, not easy to break, and has a low cost. While achieving the visual effect of a higher screen-to-body ratio, it can also provide better protection for the periphery of the electronic ink screen 6.

[0032] The first connecting member 3 is a wide nylon belt, and the length of the first connecting member 3 in the horizontal direction is 10 cm to 15 cm. In this embodiment, by adopting the first connecting member 3 as a wide nylon belt, and its length in the horizontal direction is 10 cm to 15 cm, this design can provide a certain degree of freedom for the handle to facilitate user use, and can also effectively suppress the rotation movement of the mounting bracket 7 along the vertical axis. Considering the deadweight of the frame assembly, its swing along the horizontal axis is limited, so this design can prevent the stainless steel frame 2 from swinging significantly to a certain extent, and can better protect the electronic equipment in the stainless steel frame 2. It can be understood that the mounting crossbar 5 is a crossbar used to install the handle on ordinary public transportation. Preferably, the mounting crossbar 5 is a handle mounting crossbar on a bus or a handle crossbar on a subway.

[0033] A foam buffer layer 73 is provided on one side of the installation frame 71. When the electronic ink screen 6 is installed for use, unlike a conventional static screen, the frame assembly will swing to a certain extent when public transportation is running or when held by a user, which will cause the electronic ink screen 6 to loosen in the long run. By providing the foam buffer layer 73, the impact of the swing of the frame assembly on the electronic ink screen 6 can be weakened, the electronic ink screen 6 can be better protected, and the service life of the electronic ink screen 6 can be effectively extended. Preferably, the thickness of the foam buffer layer 73 is 1.5 mm. When the thickness of the foam buffer layer 73 is set to 1.5 mm, the activity of the electronic ink screen 6 is low, and it has a certain buffering effect to cope with the mechanical impact caused by the swing of the frame assembly.

[0034] A rubber buffer layer 9 is fixedly arranged between the two symmetrically arranged mounting frames 71. Specifically, the outer shape of the rubber buffer layer 9 is in close contact with the electronic ink screen 6 in the two mounting frames 71. By providing the rubber buffer layer 9, the electronic ink screen 6 can be better protected when the frame assembly swings.

[0035] The rubber buffer layer 9 is provided with a first porous structure 91, and the first porous structure 91 is connected with two mounting frames 71. By providing the first porous structure 91, the elasticity of the first porous structure 91 can be further enhanced, and the mechanical vibration caused by the swing of the frame assembly can be better absorbed. At the same time, the first porous structure 91 also forms a certain space, which can provide a certain heat dissipation space for the electronic ink screen 6, which is conducive to the normal operation of the electronic ink screen 6 and prolongs the service life of the electronic ink screen 6.

[0036] Preferably, the rubber buffer layer 9 is also provided with a second porous structure 92, and the mounting frame 71 is provided with heat dissipation holes connected to the outside world, and the second porous structure 92 is in communication with the first porous structure 91, and the second porous structure 92 is connected to the outside world through the heat dissipation holes provided on the mounting frame 71. Specifically, the heat dissipation holes on the mounting bracket 7 are provided on the upper side or the two side edges, or are provided on the upper side and the two side edges at the same time, and the position of the second porous structure 92 corresponds to the position of the heat dissipation holes provided on the mounting bracket 7, so that the hole space in the rubber buffer layer 9 is connected to the outside world through the heat dissipation holes provided on the mounting frame 71, which can provide the electronic ink screen 6 with a strong heat dissipation performance, so as to meet the high heat dissipation requirements when the screen is frequently switched, and effectively extend the service life of the electronic ink screen 6.

[0037] The thickness of the first connecting member 3 is 2 mm to 3 mm. The thickness of the first connecting member 3 is 2 mm to 3 mm. Through the above arrangement, the first connecting member 3 with a thickness of 2 mm to 3 mm can provide sufficient strength on the one hand, and can effectively inhibit the rotational movement of the stainless steel frame 2 along the vertical axis on the other hand.

[0038] An electronic ink screen device, using any of the above-mentioned frame components, two electronic ink screens 6 are respectively installed in two symmetrically arranged installation frames 71 of the installation bracket 7. In the prior art, paper is mostly used as a public transportation handle advertising medium. This solution is time-consuming and labor-intensive when placing and replacing advertisements. At present, there are also a small number of LCD screens used as public transportation handle advertising media, but they consume a lot of power and are not conducive to cost control. In this embodiment, an electronic ink screen 6 is used as an advertising display medium. Compared with traditional paper media, its content is easy to change. Compared with LCD screens, it does not consume power when the page is fixed, and only generates a small amount of power when the page changes. It has excellent energy consumption performance. Considering that most of the advertisements on public transportation handles are fixed picture type advertisements, the replacement cycle is long. Therefore, the solution of using the electronic ink screen 6 as a public transportation handle advertising medium in this embodiment has a strong cost advantage in energy consumption.

[0039] The electronic ink screen 6 includes a power harness and a signal harness, which are arranged in the frame assembly, and the interface at the far end of the electronic ink screen 6 is arranged in the mounting crossbar 5. The electronic ink screen 6 includes a power harness and a signal harness, which are arranged in the frame assembly, and the interface at the far end of the electronic ink screen 6 is arranged in the mounting crossbar. The above-mentioned arrangement makes it possible for the power supply and signal generating device of the electronic ink screen 6 to be not in the frame assembly, further simplifying the frame assembly, which is beneficial to the manufacture and installation of the device on the one hand, and beneficial to the unified control of the electronic ink screens 6 in multiple frame assemblies on the other hand. By arranging the power harness and the signal harness in the frame assembly, not only can the exposed harness be prevented from being damaged. Preferably, the power harness and the signal harness are provided with a socket near the end of the electronic ink screen 6 to facilitate electrical connection with the electronic ink screen 6.

[0040] Example 2

[0041] Please refer to Figures 1 to 8 This embodiment provides an electronic ink screen device and a frame assembly, and its basic structure is the same as an electronic ink screen device and a frame assembly provided in Example 1, except that: the slider 811 and the limit block 821 are respectively provided with a first chamfer 8111 and a second chamfer 8211, and the first chamfer 8111 and the second chamfer 8211 can make the installation and disassembly of the mounting bracket 7 smoother.

[0042] Furthermore, a sliding rod 8212 is further provided at the end of the limit block 821 near the base 822, and a sliding hole is correspondingly provided in the base 822, and the sliding rod 8212 is slidably connected with the sliding hole in the base 822. Through the above arrangement, the stability of the structure can be further enhanced.

[0043] Furthermore, the pull ring 1 includes a stainless steel structure layer 11, a sponge filling layer 12 and a leather layer 13 which are sequentially arranged from the inside to the outside, and a wavy groove 131 is arranged on the upper side of the leather layer 13. In the arrangement of the pull ring 1, the stainless steel structure layer 11 can provide sufficient strength, the sponge filling layer 12 can provide a better gripping experience for the user, and the leather layer 13 can effectively protect the sponge filling layer 12. Preferably, the leather layer 13 is made of artificial leather, which has a lower cost and is more animal-friendly.
