Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic equipment technology, and in particular to a multicolor electronic writing notebook. Background Technology
[0002] In today's digital age, electronic writing devices are gradually becoming an important tool for people to record information and create content;
[0003] However, existing e-writing devices have the following shortcomings in actual use: On the one hand, the outer shell of most e-writing notebooks only serves a simple protective function and lacks effective cushioning design. In daily use, if accidentally dropped or bumped, it can easily lead to screen damage and loosening of internal components, affecting the normal use and lifespan of the device. On the other hand, most current e-writing notebooks simply place ordinary rubber pads or sponges between the outer shell and internal components as cushioning materials to cope with vibrations in daily use. This traditional shock absorption method lacks targeted and systematic design and cannot accurately disperse and absorb vibration energy. When subjected to a slightly larger external impact, such as an accidental drop, the vibration will still be transmitted to the internal precision components, causing problems such as dead pixels on the screen and loose solder joints on the circuit board, greatly shortening the lifespan of the device and increasing the user's maintenance costs and the risk of data loss. Utility Model Content
[0004] The main purpose of this invention is to provide a multi-color electronic writing notebook, which can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A multi-color electronic writing notebook includes a writing notebook body. The upper front part of the writing notebook body is provided with a touch button and an expansion slot. The front middle part of the writing notebook body is provided with a Type-C interface. The outer surface of the writing notebook body is covered with a protective device. The upper end of the protective device is movably connected to the left middle part of the top cover and a connecting block is fixedly connected to the right end of the connecting block. A first magnet is fixedly connected to the right end of the connecting block.
[0007] The protective device includes an outer protective shell, an inner protective shell fixedly connected to the lower inner wall of the outer protective shell, foam filling between the outer protective shell and the foam, anti-slip texture on the lower inner wall of the inner protective shell, a mounting groove in the middle of the left end of the outer protective shell, a second magnet installed in the mounting groove, and slots and headphone jack slots respectively in the front end of the outer protective shell near the Type-C interface and headphone jack. Several shock-absorbing components are fixedly connected to the inner sides of the outer and inner protective shells.
[0008] Preferably, the foam is tightly filled between the outer protective shell and the inner protective shell, and the thickness of the foam is uniform.
[0009] The above solution involves dense and evenly filling the writing pad with foam, which effectively buffers external impacts, provides all-around protection for the writing pad, reduces the risk of damage, and extends its service life.
[0010] Preferably, the anti-slip texture is regularly distributed in a concave-convex shape on the lower inner wall surface of the inner protective shell.
[0011] The above solution features a regular, uneven texture that increases the friction between the notebook and the surface it is placed on, effectively preventing accidental slippage and ensuring writing stability and device safety.
[0012] Preferably, the second magnet and the first magnet are magnetically attracted to each other, and the attraction between the two is sufficient to make the top cover fit tightly against the protective device.
[0013] The above solution allows the second magnet to attract the first magnet, making the top cover fit tightly. This effectively prevents dust and debris from entering, protecting the internal components of the notebook and preventing the top cover from accidentally opening and affecting its use.
[0014] Preferably, the shock-absorbing component includes a first connecting ring block, a spring is fixedly connected to the inner side of the first connecting ring block, and a second connecting ring block is fixedly connected to the end of the spring away from the first connecting ring block.
[0015] The above solution effectively absorbs the vibration and impact of the notebook by using a spring and connecting ring block, reducing damage to internal components and improving the device's impact resistance and service life.
[0016] Preferably, the outer side of the first connecting ring block is completely fitted with the inner side of the outer protective shell, and the outer side of the second connecting ring block is in close contact with the outer side of the inner protective shell.
[0017] Through the above scheme, the first and second connecting rings are in close contact with the inner and outer protective shells, ensuring that the shock absorption components are stably installed, so that the vibration buffering force is efficiently transmitted and the overall shock absorption performance of the protective device is enhanced.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. In this utility model, by setting up a protective device, foam cotton is tightly filled between the outer protective shell and the inner protective shell with uniform thickness. The foam cotton is soft and elastic, which can effectively disperse and absorb the impact force when the writing notebook is accidentally dropped or hit, buffering the direct impact of the outside world on the writing notebook body. At the same time, several shock-absorbing components are fixedly connected to the inner side of the outer protective shell and the inner protective shell. This structure further buffers the vibration through the expansion and contraction deformation of the spring. Compared with the traditional method of using only ordinary rubber pads or sponges, the shock-absorbing design of this device is more targeted and systematic, which can accurately disperse and absorb vibration energy, effectively preventing vibration from being transmitted to internal precision components, greatly reducing the probability of problems such as dead pixels on the screen and loose solder joints on the circuit board, thereby significantly extending the service life of the device and reducing the user's maintenance costs and data loss risk.
[0020] 2. In this utility model, the lower inner wall surface of the inner protective shell is provided with a regular, uneven anti-slip texture. This design effectively increases the friction between the notebook and the contact surface when the notebook is placed on a flat surface such as a desktop, preventing the notebook from sliding accidentally. During daily use, whether the user is writing normally or the environment is slightly tilted, the anti-slip texture can ensure that the notebook remains stable, providing the user with a more reliable user experience and avoiding writing inconvenience or even device damage due to the notebook sliding, further ensuring the safety and stability of the device.

[0029] Please see Figure 1-4 This utility model provides a technical solution:
[0030] The multi-color electronic writing notebook includes a writing notebook body 1. The upper front part of the writing notebook body 1 is provided with a touch button 2 and an expansion slot 3. The front middle part of the writing notebook body 1 is provided with a Type-C interface 4. The outer surface of the writing notebook body 1 is covered with a protective device 5. The upper end of the protective device 5 is movably connected to the top cover 6. The left middle part of the protective device 5 is fixedly connected to a connecting block 7. The right end of the connecting block 7 is fixedly connected to a first magnet 8.
[0031] In this embodiment, the protective device 5 includes an outer protective shell 51, an inner protective shell 52 is fixedly connected to the lower inner wall of the outer protective shell 51, foam 53 is filled between the outer protective shell 51 and the foam 53, the lower inner wall of the inner protective shell 52 is provided with anti-slip texture 54, an installation groove 55 is opened in the middle of the left end of the outer protective shell 51, a second magnet 56 is installed in the installation groove 55, a slot 57 and an earphone hole slot 58 are respectively opened at the front end of the outer protective shell 51 near the Type-C interface 4 and the headphone hole, and several shock-absorbing components 59 are fixedly connected to the inner sides of the outer protective shell 51 and the inner protective shell 52.
[0032] Through the above scheme: when the protective device 5 is working, the outer protective shell 51 and the inner protective shell 52 form a double layer of protection. The foam cotton 53 filling the middle can buffer impacts, the anti-slip texture 54 increases the friction with the placement surface, the second magnet 56 attracts and fixes the top cover 6 with the first magnet 8, and the slot 57 and the headphone jack slot 58 facilitate interface use. The shock absorption component 59 extends and retracts through the spring 592 to absorb vibrations and protect the writing pad body 1.
[0033] In this embodiment, foam 53 is tightly filled between the outer protective shell 51 and the inner protective shell 52, and the thickness of foam 53 is uniform; anti-slip texture 54 is regularly distributed in a concave-convex shape on the lower inner wall surface of the inner protective shell 52; the second magnet 56 and the first magnet 8 are magnetically attracted, and the attraction between the two is sufficient to make the upper cover 6 tightly adhere to the protective device 5; the shock absorption component 59 includes a first connecting ring block 591, a spring 592 is fixedly connected to the inner side of the first connecting ring block 591, and a second connecting ring block 593 is fixedly connected to the end of the spring 592 away from the first connecting ring block 591; the outer side of the first connecting ring block 591 is completely fitted with the inner side of the outer protective shell 51, and the outer side of the second connecting ring block 593 is in close contact with the outer side of the inner protective shell 52.
[0034] Through the above scheme: when the multicolor electronic writing notebook 1 is subjected to external force, the components work together. Foam 53 is tightly and evenly filled between the outer protective shell 51 and the inner protective shell 52. With its own softness and elasticity, it absorbs and disperses the impact force when the writing notebook is hit or dropped, reducing damage to the internal structure. The anti-slip texture 54 on the lower inner wall of the inner protective shell 52 increases the friction with the placement surface through regular concave and convex shapes, preventing the writing notebook from sliding accidentally. The top cover 6 is magnetically attracted to the second magnet 56 in the mounting groove 55 of the outer protective shell 51 by the first magnet 8 on the connecting block 7, and is tightly attached to the protective device 5, blocking dust, moisture and other substances from entering. In the shock absorption component 59, the first connecting ring block 591 is completely attached to the inner side of the outer protective shell 51, and the second connecting ring block 593 is in close contact with the outer side of the inner protective shell 52. The spring 592 connects the two. When vibration occurs, the spring 592 stretches and deforms, converting the vibration energy into its own elastic potential energy, weakening the transmission of vibration to the writing notebook body 1, and realizing the shock absorption function.
[0035] It should be noted that this utility model is a multi-color electronic writing notebook. Before use, the top cover 6 is magnetically attracted to the protective device 5 by the first magnet 8 and the second magnet 56, thus sealing and protecting the writing notebook body 1. When the writing notebook needs to be used, the top cover 6 is opened, and the device is turned on via the touch button 2. If an external device needs to be connected, the data cable can be inserted into the Type-C interface 4, or an expansion accessory can be inserted into the expansion slot 3. During use, if the writing notebook is accidentally dropped or impacted, the foam cotton 53 tightly filling the space between the outer protective shell 51 and the inner protective shell 52, as well as the outer protective shell 51 and the inner protective shell 52, will protect the writing notebook body. The shock-absorbing component 59 on the inner side begins to function. The foam 53 absorbs part of the impact force, and the spring 592 in the shock-absorbing component 59 converts the remaining vibration energy into elastic potential energy through expansion and contraction. The first connecting ring 591 and the second connecting ring 593 ensure that the shock-absorbing component 59 is firmly connected, thereby effectively buffering the vibration and protecting the writing notebook body 1. At the same time, the anti-slip texture 54 on the inner wall of the inner protective shell 52 can increase the friction with the placed surface and prevent the writing notebook from accidentally sliding during normal use. After use, the top cover 6 is closed again by the attraction of the first magnet 8 and the second magnet 56 to protect the writing notebook body 1 and prepare it for the next use.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
