Description

Technical Field

[0001] This application belongs to the field of electronic equipment, specifically relating to the external structure of electronic equipment, and more specifically to an electronic writing tablet carrying case and an electronic writing tablet. Background Technology

[0002] In addition to LCD handwriting tablets (which typically consist of an LCD screen and a dedicated stylus, using the deformation of liquid crystal molecules under pressure to display handwriting), electronic writing tablets also include electromagnetic induction handwriting tablets (which digitize handwriting by interacting with an induction coil on the handwriting tablet through an electromagnetic field generated by the stylus) and capacitive handwriting tablets (where the stylus changes the capacitance value on the screen when it touches it, thus enabling position detection).

[0003] Electronic writing tablets are commonly used for note-taking, daily homework, creative design, and sketching. Because of their erasable function, they can be reused repeatedly, reducing paper waste.

[0004] However, while pursuing compactness and portability, existing electronic writing tablets are also reducing their effective writing area and battery life.

[0005] Based on this, the existing foldable technology for electronic display terminals provides a solution to the aforementioned technical problems. For details, please refer to the specific implementation section of the specification of "Hinge Assembly and Foldable Electronic Device" disclosed in Chinese Invention CN202111339253.8. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a foldable electronic writing tablet that improves portability while ensuring its effective writing area, and to provide a matching carrying case. On the one hand, this solves the problem of daily protection of the writing tablet, and on the other hand, it improves its battery life by allowing the writing tablet to be charged on demand through the extended battery in the case.

[0007] Technical Solution: To address the aforementioned technical problems, this application provides a new technical solution, as follows:

[0008] An electronic writing tablet carrying case includes a box body and a box cover. The box body has an inner cavity, and at least one first limiting mechanism is provided at the bottom of the inner cavity to prevent the writing tablet from shaking inside the box.

[0009] At least one charging connector is provided at the bottom of the inner cavity; the charging connector is used to connect to the writing board to charge the writing board.

[0010] The box lid has at least one second limiting mechanism inside; the writing board is limited by the combination of the first limiting mechanism and the second limiting mechanism to prevent the writing board from shaking inside the box and causing damage.

[0011] The box contains a rechargeable battery to power the writing tablet.

[0012] A charging port is provided on the outer surface of the box for charging the battery.

[0013] Furthermore, the first limiting mechanism and the second limiting mechanism are respectively a bottom limiting groove and a top limiting groove, and the bottom and side walls of the limiting grooves are provided with cushioning pads. When the writing tablet is placed in the box, its lower end and upper end are respectively embedded in the bottom limiting groove and the top limiting groove, and the cushioning pads can provide cushioning protection for the writing tablet.

[0014] Furthermore, the charging port is located at the bottom of the box.

[0015] Furthermore, the battery is housed within a battery holder, which is located in the center of the inner cavity, with a cavity between the battery holder and the inner wall of the cavity. The folded writing tablet is placed within this cavity.

[0016] Furthermore, at least one of the bottom limiting grooves has an enlarged hole, and the charging connector is located inside the enlarged hole. The charging connector is a magnetic two-prong charging socket. Springs can be installed on the bottom of the charging feet to improve the connection stability during charging.

[0017] Furthermore, the box body includes the box body and the electronic assembly. The box body is a triangular prism with rounded corners at the edges. One end of the internal shell serves as the box opening and the other end serves as the box bottom. The bottom limiting groove is located at the bottom of the box and is a triangular slot.

[0018] The bottom of the battery holder is located in the middle of the bottom of the box. The hollow outer contour inside is stretched towards the opening of the box, and the stretched length is lower than the surface where the opening of the box is located. The opening of the battery holder is located on the bottom outer end face of the box body.

[0019] The electronic assembly includes a housing and an internal PCB board mounting base. The battery is a cylindrical lithium-ion battery connected to the electronic assembly.

[0020] The cross-sectional profile of the housing is the same as that of the box body. One end of the housing connected to the battery is bonded to the box body. The battery is embedded in the battery holder through the battery holder opening. The other end serves as the end of the box body, and its surface is provided with a charging interface.

[0021] A display screen is also installed at the end of the box.

[0022] Furthermore, the box body is equipped with a hook, located near the opening of the box. When carrying it with the hanging rope, the opening should face upwards to prevent the lid from falling off and the writing board from spilling out.

[0023] A permanent magnet is provided at the joint between the lid and the body of the box.

[0024] This application also provides an electronic writing tablet, hereinafter referred to as the "writing tablet," which has at least two hinge mechanisms. The writing tablet can be folded along the hinge mechanisms, and the folded outline is smaller than the cavity. The thickness of the electronic writing tablet is smaller than the bottom limiting groove and the top limiting groove. When folded into a triangular prism shape, it fits into the cavity inside the aforementioned box body.

[0025] Furthermore, a protrusion is provided on the left or right side of the writing tablet, extending through the top and bottom ends of the electronic writing tablet. The cross-sectional outline of the protrusion is the same as that of the enlarged hole, but its area is smaller than that of the enlarged hole. The protrusion of the writing tablet is used to install a battery and related electronic components. These electronic components include a Bluetooth module, as well as at least one data cable connector and related components, which can be connected to other electronic devices via Bluetooth or a data cable.

[0026] Furthermore, a magnetic foot is provided at the lower end of the protrusion for connection with the charging connector. The data cable interface is located at the upper end of the protrusion.

[0027] The beneficial effects of this application are as follows:

[0028] The electronic writing tablet features a folding design achieved through a hinge structure, reducing its size and making it easy to carry. When folded, the tablet fits snugly into the interior of the triangular prism-shaped case. The case's internal restraint mechanisms and cushioning effectively prevent the tablet from shifting or getting damaged, enhancing its protective performance.

[0029] The carrying case not only significantly improves the portability of the writing tablet, but also includes a rechargeable battery and charging connector, allowing the tablet to be charged anytime while on the go. The external charging port also allows for recharging the battery, ensuring extended use of the writing tablet while traveling.

[0030] The charging connector inside the carrying case features a magnetic design, which can be further enhanced by adding a spring to improve the connection stability when the writing tablet is placed inside the case, ensuring a smoother charging process.

[0031] The writing board features a raised structure to accommodate electronic components such as a battery, Bluetooth module, and data cable interface, enabling it to connect to external devices via Bluetooth or data cable, thus expanding the writing board's application range and interactive functions.

[0032] The hook design on the top of the box allows users to carry it with a lanyard. The hook is located at the top of the box to avoid stress on the lid when carrying it with a lanyard. A permanent magnet is also installed to keep the lid stable and prevent it from opening accidentally, thus improving safety during carrying. Attached Figure Description
