Description

Technical Field

[0001] The utility model relates to the technical field of handwriting tablets, in particular to a liquid crystal handwriting tablet with a laser distance measurement function. Background Art

[0002] A pen tablet is an input device used for handwriting and drawing. Typically, text is written in a specific area using a special pen or finger. The tablet records the pen or finger's path through various methods and then recognizes it as text. This is very useful for people who dislike using keyboards or are unfamiliar with Chinese input methods, as there's no need to learn an input method. Pen tablets can also be used for precise drawing, such as in circuit design, CAD design, graphic design, freehand drawing, and text and data input.

[0003] For example, Chinese patent document CN218512936U discloses a liquid crystal tablet with a laser ranging function, comprising a bottom shell and a lock screen assembly. A battery panel is fixedly connected to the bottom shell, and a mainboard is connected to the rear of the battery panel. A liquid crystal panel is fixedly connected to the upper portion of the mainboard. The lock screen assembly, which is used to lock the screen, is located at the right rear portion of the bottom shell. The lock screen assembly includes a card cavity, a card slot, a sealing plate, a shifting block, a touch pad, a spring, and a contact. The bottom shell has a card cavity at the right rear portion, and card slots are symmetrically provided on the upper and lower sides of the card cavity. A sealing plate is embedded in the card slot, and a shifting block is fixedly connected to the right side of the card plate. A touch pad is fixedly connected to the left side of the card plate, and a spring is fixedly connected below the touch pad. A contact is provided to the left of the spring, and the contact is fixedly connected to the mainboard. The coordination of these components prevents interruptions in operation caused by accidentally touching the lock screen button while using the tablet, and prevents dust from entering the tablet without affecting the tablet's heat dissipation.

[0004] However, the above-mentioned liquid crystal handwriting tablet is large in size and inconvenient to carry. Secondly, if the force of accidentally touching the dial block is large, the touch panel can still be driven down to the contact point, thereby locking the screen and interrupting the operation.

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] See also Figure 1-3The utility model provides a technical solution: a liquid crystal handwriting tablet with a laser ranging function, comprising a titanium alloy shell A1, a titanium alloy shell B2 being hingedly installed on one side of the titanium alloy shell A1, and when not in use, the other side of the titanium alloy shell B2 can be manually pushed to close the titanium alloy shell B2 on the top of the titanium alloy shell A1, thereby reducing the length of the liquid crystal handwriting tablet and facilitating the carrying of the liquid crystal handwriting tablet. The first protective film 6 and the second protective film 8 can also be protected to avoid scratches on the first protective film 6 and the second protective film 8. The top of the titanium alloy shell A1 and the top of the titanium alloy shell B2 are both provided with openings. A battery 3 is fixedly installed on the inner bottom of A1, a control mainboard 4 is fixedly installed on the top of the battery 3, a first display screen 5 is fixedly installed on the top of the control mainboard 4, a first protective film 6 is pasted on the top of the first display screen 5, a second display screen 7 is fixedly installed on the inner bottom of the titanium alloy shell B2, a second protective film 8 is pasted on the top of the second display screen 7, and it also includes a clear key 9 arranged on the front side of the control mainboard 4, a lock screen key 10 arranged on one side of the control mainboard 4, and the lock screen key 10 is in contact with one side of the titanium alloy shell B2, and a connecting block 16 is fixedly installed on the outer wall of the other side of the titanium alloy shell A1, and a pen slot is provided on the top of the connecting block 16, and a stylus 18 is placed in the pen slot.

[0023] One side of the first display screen 5 is in contact with one side of the second display screen 7 , and one side of the first protective film 6 is in contact with one side of the second protective film 8 .

[0024] A third magnetic block 13 is embedded in the top of the titanium alloy shell A1, and a fourth magnetic block 14 is embedded in the top of the titanium alloy shell B2. The third magnetic block 13 and the fourth magnetic block 14 are attracted to each other. Due to the attraction between the third magnetic block 13 and the fourth magnetic block 14, the adsorption between the titanium alloy shell A1 and the titanium alloy shell B2 is increased, preventing the titanium alloy shell A1 and the titanium alloy shell B2 from opening and closing during the carrying process.

[0025] A first magnetic block 11 is embedded in one side of the titanium alloy shell A1, and a second magnetic block 12 is embedded in one side of the titanium alloy shell B2. The first magnetic block 11 and the second magnetic block 12 are attracted to each other. Due to the attraction between the first magnetic block 11 and the second magnetic block 12, the strength between one side of the titanium alloy shell A1 and one side of the titanium alloy shell B2 can be increased. During use, the bending of the titanium alloy shell A1 and the titanium alloy shell B2 is reduced, ensuring normal use by users.

[0026] A circular hole A is provided on the front side of the titanium alloy shell A1, and the clear key 9 is located in the circular hole A. A circular hole B is provided on one side of the titanium alloy shell A1, and the lock screen key 10 is located in the circular hole B. During use, the titanium alloy shell B2 will block the lock screen key 10 on one side of the titanium alloy shell A1, preventing the user from touching the lock screen key 10, thereby fundamentally solving the problem of accidentally touching the lock screen.

[0027] Both sides of the pen slot are provided with protrusions 17 for confining the stylus 18 in the pen slot and preventing the stylus 18 from falling out of the pen slot during carrying.

[0028] A second slot 19 is provided on the front and rear sides of the pen slot to facilitate taking out the stylus 18 in the pen slot.

[0029] A first slot 15 is formed on the other side of the titanium alloy housing B2 to facilitate unfolding of the liquid crystal writing tablet.

[0030] Working principle: When not in use, the other side of the titanium alloy shell B2 can be manually pushed to close the titanium alloy shell B2 on the top of the titanium alloy shell A1, thereby reducing the length of the liquid crystal handwriting tablet and facilitating carrying the liquid crystal handwriting tablet. Due to the attraction of the third magnetic block 13 and the fourth magnetic block 14, the adsorption between the titanium alloy shell A1 and the titanium alloy shell B2 is increased. During the carrying process, the titanium alloy shell A1 and the titanium alloy shell B2 are prevented from opening and closing. When needed, the titanium alloy shell B2 can be manually pushed to unfold the titanium alloy shell B2. Due to the attraction of the first magnetic block 11 and the second magnetic block 12, the strength between one side of the titanium alloy shell A1 and the other side of the titanium alloy shell B2 can be increased. During use, the bending of the titanium alloy shell A1 and the titanium alloy shell B2 is reduced to ensure normal use by the user.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
