Description

Technical Field

[0001] This utility model relates to the field of inkjet screen technology, and in particular to an inkjet screen with magnetic attraction function. Background Technology

[0002] E-ink devices refer to electronic devices that use electronic ink screens. Also known as e-ink displays or electronic paper display technology, e-ink screens do not emit light themselves but rely on external light reflection to achieve a display effect. Their display effect is very similar to paper materials, thus providing a comparable reading experience. E-ink screens are generally standalone electronic devices. Users can use them like mobile phones, making them more flexible. However, this also makes them inconvenient to carry. As standalone electronic devices with a structure and size similar to mobile phones, users carrying both a mobile phone and an e-ink screen are more likely to lose one without timely detection, leading to complete loss of the device and affecting device stability and user experience. Utility Model Content

[0003] The main purpose of this utility model is to provide a water-ink screen with magnetic attraction function, which aims to make the water-ink screen itself easy to store and fix, and to prevent the device from being lost.

[0004] To achieve the above objectives, this utility model proposes a water-based ink screen with magnetic attraction function, comprising a shell, a magnetic attraction mechanism, and a screen structure. The shell has an installation cavity, and the installation cavity has a control motherboard relative to the screen structure. The screen structure is electrically connected to the control motherboard, and the outer periphery of the screen structure is connected to the inner wall of the shell and covers one end of the installation cavity.

[0005] The inner wall of the housing is provided with a fixing frame facing the mounting cavity. The fixing frame is wrapped around the magnetic attraction mechanism and has a fixing structure relative to the control motherboard and / or the magnetic attraction mechanism.

[0006] In one embodiment of this application, the control motherboard includes a main control unit and a connection unit. The main control unit is provided with a main control chip and connected to a battery. The main control unit is connected to the connection unit, and the connection unit is provided with a connection unit and control buttons.

[0007] The outer casing has a through hole relative to the connecting unit, and the outer casing has a mounting part relative to the control button.

[0008] In one embodiment of this application, a clearance groove is provided between the main control part and the connecting part, the magnetic attraction mechanism passes through the clearance groove and is connected to the inner wall of the outer shell, and the magnetic attraction mechanism surrounds the main control part.

[0009] In one embodiment of this application, the outer casing includes a screen protective shell, a mounting frame, and a base plate. One end of the mounting frame is connected to the screen protective shell, and the other end is connected to the base plate. The screen protective shell is located above the screen structure, and the control motherboard and the magnetic attraction mechanism are connected to the mounting frame.

[0010] In one embodiment of this application, the outer periphery of the mounting frame is provided with a connecting structure away from the mounting cavity.

[0011] By adopting the above technical solution, this utility model has the following advantages:

[0012] 1. The structure and size of an e-ink screen are similar to those of a mobile phone, and mobile phones are now essential devices for people when they go out. To prevent the e-ink screen from being lost, it needs to be able to be quickly and stably fixed in certain positions. To achieve this goal, the structure of the e-ink screen itself includes a casing to protect the entire device, a magnetic mechanism to assist in quickly fixing the e-ink screen in a certain place, and the core screen structure of the e-ink screen. The casing has a mounting cavity to house the control motherboard and the magnetic mechanism. The magnetic mechanism allows the e-ink screen to be stably attached to a specific place. In particular, many existing mobile phone cases have magnets installed inside, making it easy to fix the phone. The magnetic structure inside the e-ink screen in this application can also achieve the same function. When the user's mobile phone case has a magnetic function, the e-ink screen can be directly fixed to the back of the phone, so that the e-ink screen can be firmly installed on the phone. Without significantly increasing the weight of the carrying items, the phone and the e-ink screen can protect each other and prevent the device from being lost. Furthermore, the magnetic mechanism on the e-ink screen can achieve quick storage and fixation of the e-ink screen itself, and the structure is easy to disassemble, which can effectively improve the user experience.

[0013] 2. The outer shell has a fixed frame inside the mounting cavity. The fixed frame can be used to form a fixed cavity that can be fully adapted to the magnetic suction mechanism. The magnetic suction mechanism can be installed and locked through a fixed cavity of the same area. This fixing method is simple and effective. The installed magnetic suction mechanism is easy to remove and maintain, which can effectively reduce costs. The fixed frame can fix the magnetic suction mechanism in the center of gravity area of ​​the entire e-ink screen with magnetic suction function, so that the e-ink screen can be more stable when fixed with the magnetic suction mechanism, and avoid the magnetic suction mechanism from falling off due to uneven force on the e-ink screen.

[0014] 3. To prevent the magnetic suction mechanism from detaching from the fixed frame and damaging the control motherboard, or to prevent the control motherboard from being loosely fixed and scraping against the magnetic suction mechanism, the fixed frame has a fixing structure relative to the control motherboard and / or the magnetic suction mechanism. The fixing structure itself can have various structural states, and its main purpose is to lock the components installed in the mounting cavity to prevent them from loosening. The specific fixing structure can be a locking component with a self-locking mechanism, using ball bearings and springs to lock the magnetic suction mechanism after it is installed, preventing it from falling off. Alternatively, it can be a fixing block, allowing the control motherboard to be inserted into the fixing block for quick locking, which can effectively improve the service life of the equipment.

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Reference Figures 1 to 2To achieve the above objectives, this utility model proposes a water-ink screen with magnetic attraction function, which includes a shell 1, a magnetic attraction mechanism 4, and a screen structure 5. The shell 1 is provided with an installation cavity 22, and the installation cavity 22 is provided with a control motherboard 3 opposite to the screen structure 5. The screen structure 5 is electrically connected to the control motherboard 3, and the outer periphery of the screen structure 5 is connected to the inner wall of the shell 1 and sealed to one end of the installation cavity 22.

[0023] The inner wall of the outer casing 1 is provided with a fixing frame 21 facing the mounting cavity 22. The fixing frame 21 is wrapped around the magnetic attraction mechanism 4 and is provided with a fixing structure relative to the control motherboard 3 and / or the magnetic attraction mechanism 4.

[0024] The structure and size of an e-ink screen are similar to those of a mobile phone, and mobile phones are now essential devices for people to carry when going out. To prevent the e-ink screen from being lost, it needs to be able to be quickly and stably fixed in a certain position. To achieve this goal, the structure of the e-ink screen itself includes a shell 1 for protecting the entire device, a magnetic attraction mechanism 4 for assisting the e-ink screen to be quickly fixed in a certain place, and the core screen structure 5 of the e-ink screen. The shell 1 houses the control motherboard 3 and the magnetic attraction mechanism 4 through a mounting cavity 22. The magnetic attraction mechanism 4 allows the e-ink screen to be stably attracted to a specific place. In particular, many existing mobile phone cases have magnets installed inside, making it easy to fix the phone. The magnetic structure inside the e-ink screen in this application can also achieve the same function. When the user's mobile phone case has a magnetic attraction function, the e-ink screen can be directly fixed to the back of the phone, so that the e-ink screen can be firmly installed on the phone. Without significantly increasing the weight of the carrying items, the phone and the e-ink screen can protect each other and prevent the device from being lost. Furthermore, the magnetic attraction mechanism 4 on the e-ink screen can achieve quick storage and fixation of the e-ink screen itself, and this structure is easy to disassemble, which can effectively improve the user experience.

[0025] The outer casing 1 has a fixing frame 21 inside the mounting cavity 22. The fixing frame 21 can form a fixed cavity that can fully fit the magnetic suction mechanism 4 inside the mounting cavity 22. The magnetic suction mechanism 4 can be installed and locked through the fixed cavity of the same area. This fixing method is simple and effective. The installed magnetic suction mechanism 4 is easy to remove and maintain, which can effectively reduce costs. The fixing frame 21 can fix the magnetic suction mechanism 4 in the center of gravity area of ​​the entire e-ink screen with magnetic suction function, so that the e-ink screen can be more stable when fixed with the magnetic suction mechanism 4, and avoid the magnetic suction mechanism 4 from falling off due to uneven force on the e-ink screen.

[0026] To prevent the magnetic suction mechanism 4 from falling out of the fixed frame 21 and damaging the control motherboard 3, or to prevent the control motherboard 3 from being loosely fixed and scraping against the magnetic suction mechanism 4, the fixed frame 21 has a fixing structure relative to the control motherboard 3 and / or the magnetic suction mechanism 4. The fixing structure itself can have various structural states, and its main purpose is to lock the components installed in the mounting cavity 22 to prevent them from loosening. The specific fixing structure can be a locking part with a self-locking structure. Using ball bearings and springs, the ball bearings can lock the magnetic suction mechanism 4 after it is installed, which can prevent the magnetic suction mechanism 4 from falling off. Alternatively, it can be a fixing block, which allows the control motherboard 3 to be inserted into the fixing block for quick locking, which can effectively improve the service life of the equipment.

[0027] See also Figure 1 In one embodiment of this application, the control motherboard 3 includes a main control unit 31 and a connection unit 32. The main control unit 31 is provided with a main control chip and connected to a battery. The main control unit 31 is connected to the connection unit 32. The connection unit 32 is provided with a connection unit and control buttons.

[0028] The outer casing 1 has a through hole relative to the connecting unit, and the outer casing 1 has a mounting part relative to the control button.

[0029] The control motherboard 3 contains the control chip and components for the entire e-ink screen, as well as a card slot for easy connection of external memory cards, a USB interface for external charging, and many other connection units. The control buttons used by the user to operate the e-ink screen and the battery that powers the entire e-ink screen are also all connected to the control motherboard 3.

[0030] To better protect the core chips and components on the control motherboard 3, these chips and components need to be installed in the middle area of ​​the outer casing 1. The control motherboard 3 has a main control unit 31 in the middle area facing the mounting cavity 22, which is used to connect the control chips and components. A connecting part 32 is connected to the outer periphery of the main control unit 31. The two have a clear division of labor, which can be installed more stably and safely in the mounting cavity 22, so that the main control chip can be protected, and the external connection cable can be connected to the e-ink screen more conveniently, so that the e-ink screen can perform many functions such as downloading books and charging, which can effectively improve the user experience.

[0031] See also Figure 1 In one embodiment of this application, a clearance groove is provided between the main control unit 31 and the connecting part 32, the magnetic attraction mechanism 4 passes through the clearance groove and is connected to the inner wall of the outer shell 1, and the magnetic attraction mechanism 4 surrounds the main control unit 31.

[0032] To protect the core components, the main control unit 31 is located in the center of the mounting cavity 22, facing the control motherboard 3. In order to ensure that the e-ink screen can be installed and fixed stably, the magnetic suction mechanism 4 is also located in the middle of the mounting cavity 22. In order to allow the main control motherboard and the magnetic suction mechanism 4 to coexist and be installed stably, a clearance groove is provided between the main control unit 31 and the connecting part 32. The magnetic suction mechanism 4 can wrap around the main control unit 31 through the clearance groove, so that the e-ink screen has a high degree of integration, which can maximize the space utilization, reduce the weight of the e-ink screen itself, reduce the size of the e-ink screen to make it easy to carry, and also reduce the production cost of the e-ink screen.

[0033] See also Figures 1 to 2 In one embodiment of this application, the outer shell 1 includes a screen protective shell 11, a mounting frame 2, and a base plate 12. One end of the mounting frame 2 is connected to the screen protective shell 11, and the other end is connected to the base plate 12. The screen protective shell 11 is located above the screen structure 5. The control motherboard 3 and the magnetic suction mechanism 4 are connected to the mounting frame 2.

[0034] The outer casing 1 includes a screen protective shell 11, a mounting frame 2, and a base plate 12. The screen protective shell 11 protects the screen structure 5 and serves as an external protective screen for the e-ink screen, preventing damage to the screen structure 5 during use. The mounting frame 2 is the overall support structure for the e-ink screen, providing good protection and preventing damage to the control motherboard 3 and the magnetic attraction mechanism 4. It also facilitates the installation of the base plate 12. The base plate 12 is detachably connected to the mounting frame 2. The detachable base plate 12 makes it easy to install the control motherboard 3 and the magnetic attraction mechanism 4. The base plate 12 can be made of high-strength glass or aluminum. These materials are lightweight and have good strength. Even aluminum will not affect the magnetic attraction mechanism 4 itself. They all have good magnetic conductivity, allowing the e-ink screen to be more firmly attached to the designated position. The aluminum material is connected to the control motherboard 3. As a metal, aluminum has good thermal conductivity, which can quickly dissipate heat for the entire e-ink screen and effectively improve the service life of the device.

[0035] Furthermore, when aluminum is used as the base plate 12, the base plate 12 can be anodized. This can reduce the cost of aluminum without significantly increasing its weight. Aluminum oxide has good isolation properties and can uniformly and stably protect the stability of the base plate 12, preventing damage to the base plate 12.

[0036] See also Figure 1 In one embodiment of this application, the outer periphery of the mounting frame 2 is provided with a connecting structure away from the mounting cavity 22.

[0037] To further facilitate portability of the e-ink screen, a connecting structure can be provided on the mounting frame 2. The connecting structure is generally a connecting groove set inward at the corner of the mounting frame 2. The connecting groove has a connecting rod on the outer periphery of the mounting frame 2. By using the connecting rod and the connecting groove in conjunction, the e-ink screen can be connected to an external hook and / or lanyard. Users can use the lanyard to hang the e-ink screen around their neck, making the e-ink screen easy to use and carry, effectively preventing the e-ink screen from being lost, and improving the user experience.
