Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of handwriting tablets, and in particular to a handwriting tablet with a card switching function. Background Art
[0002] Currently, more and more devices on the market (such as handwriting tablets, cameras, etc.) have the function of switching cards. Usually, a card slot is provided on the device. By inserting the card into the card slot, the device will read the card information and provide corresponding feedback (such as sound prompts, vibration feedback, etc.). In other words, if the device wants to switch cards, it needs to manually pull out the current card from the card slot and insert other cards instead. The manual plug-in and pull-out switching method is not only inefficient, but also may increase the risk of card damage. In addition, since each pattern corresponds to a card, if the device wants to read multiple patterns, the number of cards required is very large, and the cards are inconvenient to store and easy to lose, which greatly increases the production cost. Summary of the invention
[0003] In view of this, the present application provides a handwriting tablet with a card switching function to facilitate switching between multiple patterns.
[0004] The present application provides a handwriting tablet with a card switching function, the handwriting tablet comprising a shell, the handwriting tablet comprising a first rotating shaft and a second rotating shaft arranged side by side in the shell, a pattern roll, and a window arranged in the shell; the pattern roll is provided with a plurality of patterns in sequence along the length direction, the two ends of the pattern roll are respectively fixed to the first rotating shaft and the second rotating shaft and part of the pattern roll is respectively wound on the first rotating shaft and the second rotating shaft from the two ends, so that the pattern roll located between the two rotating shafts displays one or more patterns through the window; the first rotating shaft and the second rotating shaft can be operably rotated to drive the pattern roll to scroll accordingly, so that the pattern displayed in the window is switched.
[0005] The above-mentioned handwriting tablet with card switching function has multiple patterns preset in sequence along the length direction on the pattern roll, and the two ends of the pattern roll are respectively fixed to the first rotating shaft and the second rotating shaft, and part of the pattern roll is respectively wound on the first rotating shaft and the second rotating shaft from the two ends, so that the first rotating shaft and the second rotating shaft can be operably rotated to drive the pattern roll to scroll accordingly, thereby switching the pattern displayed in the window.

[0033] Please see Figure 3 , Figure 3 The structure of each component in the handwriting tablet provided by an embodiment of the present application is illustrated. The present application provides a handwriting tablet 1 with a card switching function, the handwriting tablet 1 comprising a housing 11, a first rotating shaft 12, a second rotating shaft 13, a pattern roll 14, a window 1110, and a liquid crystal film 19. Among them, the window 1110 is arranged on the housing 11, the first rotating shaft 12, the second rotating shaft 13, the pattern roll 14, and the liquid crystal film 19 are arranged inside the housing 11, the liquid crystal film 19 is located between the window 1110 and the pattern roll 14, and the liquid crystal film 19 is partially exposed to the housing 11 through the window 1110. A plurality of patterns are arranged on one side of the pattern roll 14 close to the window 1110, and the pattern roll 14 rolls on the first rotating shaft 12 and the second rotating shaft 13, so that the plurality of patterns are sequentially displayed to the user through the window 1110.
[0034] In this embodiment, when the handwriting tablet 1 is working, the liquid crystal film 19 is black, and the liquid crystal film 19 is used for writing by the user, and the pattern on the pattern roll 14 is blocked by the liquid crystal film 19 and is not displayed. When the handwriting tablet 1 is not working, the liquid crystal film 19 is transparent, so that the pattern on the pattern roll 14 can be displayed through the liquid crystal film 19, and the liquid crystal film 19 is not used for writing by the user.
[0035] The pattern coil 14 is provided with a plurality of patterns in sequence along the length direction, and the size of each pattern and the interval between each pattern can be set according to actual needs so that the window 1110 displays one or more patterns each time. In the present embodiment, the size of each pattern is the same and is arranged at equal intervals so that the window 1110 displays one pattern each time. In the present embodiment, the handwriting board 1 can be used for early childhood education, memory learning, interest cultivation, etc. Correspondingly, the plurality of patterns in the pattern coil 14 can be elements for basic cognition such as animals, plants, shapes, Chinese characters and pinyin, or can be words, phrases, formulas of subjects such as mathematics, physics, chemistry, and even fingerings, chords, and music fragments of musical instruments. In addition, the number of patterns is set according to actual needs and is not limited here.
[0036] Please refer to Figure 1-2 , Figure 1 The front structure of a handwriting tablet provided by an embodiment of the present application is shown in FIG. Figure 2The back structure of the handwriting board provided in one embodiment of the present application is illustrated. The housing 11 includes an upper housing 111 and a lower housing 112. The upper housing 111 and the lower housing 112 are respectively located on opposite sides of the pattern roll 14. The upper housing 111 is arranged on one side of the pattern roll 14 where multiple patterns are arranged, and the lower housing 112 is arranged on the other side of the pattern roll 14. The upper housing 111 and the lower housing 112 are combined to accommodate the first rotating shaft 12, the second rotating shaft 13, and the pattern roll 14 and other components in the housing 11. Among them, the window 1110 is arranged on the upper housing 111 and passes through the upper housing 111. The size of the window 1110 can be set according to actual needs and is not limited here.
[0037] Please refer to Figure 4 , Figure 4 The internal structure of the handwriting board provided by one embodiment of the present application is illustrated. The first rotating shaft 12 and the second rotating shaft 13 are arranged side by side in the housing 11, with a certain interval between the two, and the window 1110 is located in the interval between the first rotating shaft 12 and the second rotating shaft 13. The two ends of the pattern roll 14 are respectively fixed to the first rotating shaft 12 and the second rotating shaft 13, and part of the pattern roll 14 is wound on the first rotating shaft 12 and the second rotating shaft 13 from the two ends, so that the pattern roll 14 located between the two rotating shafts 12 and 13 is flat and displays one or more patterns through the window 1110. It can be understood that when one of the first rotating shaft 12 and the second rotating shaft 13 rotates, the pattern roll 14 is driven to transmit, and then the other is driven to rotate in the same direction, so that the pattern roll 14 located between the two rotating shafts 12 and 13 is always flat.
[0038] Furthermore, the handwriting tablet 1 further includes a first knob 121 and a second knob 131 fixed at the ends of the first rotating shaft 12 and the second rotating shaft 13 and exposed outside the housing 11, and the first knob 121 and the second knob 131 are respectively used by the user to operate the two rotating shafts 12 and 13. The first rotating shaft 12 and the second rotating shaft 13 are respectively arranged in parallel on the left and right sides of the window 1110, and the first knob 121 and the second knob 131 are located on the upper side of the window 1110. The first knob 121 is used to pull the pattern roll 14 to move to the left to increase the length of the pattern roll 14 wound on the first rotating shaft 12, and the second knob 131 is used to pull the pattern roll 14 to move to the right to increase the length of the pattern roll 14 wound on the second rotating shaft 13. It can be understood that when one of the first rotating shaft 12 and the second rotating shaft 13 rotates, the other will be driven to rotate in the same direction. Therefore, the user only needs to operate one of the first knob 121 or the second knob 131 to switch the pattern of the handwriting board 1. In addition, in the present application, there is tension on the pattern roll 14 between the two rotating shafts 12 and 13, so that the pattern roll 14 between the two rotating shafts 12 and 13 is always flat, and when the first knob 121 is adjusted to the right or the second knob 131 is adjusted to the left, the tension of the pattern roll 14 will hinder the adjustment of the two, that is, the first knob 121 is only used for adjustment to the left, and the second knob 131 is only used for adjustment to the right.
[0039] Please refer to Figure 7-8 , Figure 7 and Figure 8 The first shaft 12 and the second shaft 13 can be operatively rotated to drive the pattern roll 14 to roll accordingly, so that the pattern displayed in the window 1110 is switched. In this embodiment, when the user adjusts the first knob 121 to the left (counterclockwise), the pattern roll 14 is transmitted from the first rotating shaft 12 to the second rotating shaft 13, and the length of the pattern roll 14 wound on the first rotating shaft 12 gradually decreases, and the length of the pattern roll 14 wound on the second rotating shaft 13 gradually increases, so that the pattern roll 14 originally wound on the first rotating shaft 12 can be moved into the window 1110, and the pattern displayed in the window 1110 is switched to the adjacent pattern on the left side of the current pattern; when the user adjusts the second knob 131 to the right (clockwise), the pattern roll 14 is transmitted from the second rotating shaft 13 to the first rotating shaft 12, and the length of the pattern roll 14 wound on the second rotating shaft 13 gradually decreases, and the length of the pattern roll 14 wound on the first rotating shaft 12 gradually increases, so that the pattern roll 14 originally wound on the second rotating shaft 13 can be moved into the window 1110, and the pattern displayed in the window 1110 is switched to the adjacent pattern on the right side of the current pattern.
[0040] Please refer to Fig. 9 , Fig. 9 The cross-sectional structure of the mounting seat provided in the embodiment of the present application is illustrated. The handwriting tablet 1 also includes a mounting seat 20, and the mounting seat 20 is provided with a mounting hole 201, and the other ends of the first rotating shaft 12 and the second rotating shaft 13 are inserted into the mounting hole 201 to be rotatably connected with the corresponding mounting seat 20. The mounting hole 201 is provided with a rotation area 2011 and a clamping area 2012 in sequence along the direction away from the first rotating shaft 12 and the second rotating shaft 13. Among them, the rotation area 2011 is used to rotate with the first rotating shaft 12 or the second rotating shaft 13. The aperture of the clamping area 2012 is smaller than the aperture of the rotation area 2011, and is used to clamp the first rotating shaft 12 or the second rotating shaft 13. It can be understood that the aperture of the rotation area 2011 is larger, and the first rotating shaft 12 or the second rotating shaft 13 can rotate freely in the rotation area 2011, and at this time, the first knob 121 or the second knob 131 is in a free state. The aperture of the clamping area 2012 is smaller, and the first rotating shaft 12 or the second rotating shaft 13 will encounter resistance from the clamping area 2012 when rotating in the clamping area 2012, thereby hindering the first rotating shaft 12 or the second rotating shaft 13 from rotating. At this time, the first knob 121 or the second knob 131 is in a clamping state.
[0041] Further, the first knob 121 or the second knob 131 can be pressed by the user to drive the other end of the corresponding first rotating shaft 12 or the second rotating shaft 13 to move from the rotation area 2011 to the clamping area 2012, so that the first knob 121 or the second knob 131 enters a clamping state. When the first knob 121 or the second knob 131 is rotated in the clamping state, the first knob 121 or the second knob 131 will pop out to drive the other end of the corresponding first rotating shaft 12 or the second rotating shaft 13 to move from the clamping area 2012 to the rotation area 2011, so that the first knob 121 or the second knob 131 enters a free state. It can be understood that the first knob 121 or the second knob 131 can be rotated by the user in both the free state and the clamping state, but it is more difficult to rotate the first knob 121 or the second knob 131 in the clamping state. Therefore, when the user adjusts the pattern to an appropriate position in window 1110, the user can press first knob 121 or second knob 131 to clamp first knob 121 or second knob 131 to prevent the first knob 121 or second knob 131 from being accidentally touched and causing the pattern position to shift.
[0042] Please refer to Figure 5 , Figure 5The structure of the combination of the pattern roll and the flat pressing part provided in one embodiment of the present application is illustrated. The handwriting board 1 is also provided with a flat pressing part 15 parallel to the window 1110, and the flat pressing part 15 is fixedly installed between the two rotating shafts 12 and 13, and the flat pressing part 15 is located between the pattern roll 14 and the liquid crystal film 19. The flat pressing part 15 is concave inward on the side close to the pattern roll 14, and the lower shell 112 is provided with a support part 1122 protruding toward the pattern roll 14 to support the pattern roll 14, so that the pattern roll 14 moves under the restriction of the support part 1122 and the flat pressing part 15, thereby improving the stability of the movement of the pattern roll 14. Among them, the flat pressing part 15 is made of transparent material, so that the pattern on the pattern roll 14 can be displayed in the window 1110 through the flat pressing part 15. In this embodiment, one of the flat pressing portion 15 and the lower shell 112 is provided with a positioning column 1121 , and the other is provided with a positioning hole 151 . The positioning column 1121 is inserted into the positioning hole 151 to fix the flat pressing portion 15 inside the shell 11 .
[0043] Please see again Figure 3 The handwriting tablet 1 also includes a circuit board 16, a power button 161, a voice broadcast module 17, and a reading pen 18. The voice broadcast module 17 and the circuit board 16 are fixedly installed inside the housing 11, the reading pen 18 is detachably installed inside the housing 11 and partially exposed outside the housing 11 for user operation, and the power button 161 is fixed on the circuit board 16 and partially exposed outside the housing 11 for user operation. A control circuit (not shown) and an infrared sensor (not shown) are provided on the circuit board 16, and the user controls the power on and off of the control circuit by operating the power button 161. The infrared sensor is used to sense the pattern currently displayed in the window 1110.
[0044] Please refer to Figure 6 , Figure 6 The pattern coil with multiple patterns provided in one embodiment of the present application is illustrated. The voice broadcast module 17, the point reading pen 18, and the infrared sensor are respectively connected to the control circuit for communication. The voice broadcast module 17, the point reading pen 18, the infrared sensor, and the control circuit cooperate with each other to realize the broadcast of the pattern-related content currently displayed in the window 1110. Specifically, when the user touches the pattern currently displayed in the window 1110 through the point reading pen 18, the infrared sensor senses the pattern currently displayed in the window 1110 to generate corresponding sensing data and transmit it to the control circuit. The control circuit recognizes the sensing data and controls the voice broadcast module 17 to broadcast the pattern-related content currently displayed in the window 1110. In this embodiment, the patterns include but are not limited to goats, zebras, monkeys, elephants, squirrels, tigers, dogs, cats, lions, mice, pandas, foxes, cows, etc. Correspondingly, the voice broadcast module 17 is preset with the voice content corresponding to the above-mentioned multiple patterns. Among them, the voice content can be Chinese, English, French, etc., which is not limited here.
[0045] In the above embodiment, a plurality of patterns are preset in sequence on the pattern roll along the length direction, and the two ends of the pattern roll are respectively fixed to the first rotating shaft and the second rotating shaft, and parts of the pattern roll are respectively wound on the first rotating shaft and the second rotating shaft from the two ends, so that the first rotating shaft and the second rotating shaft can be operably rotated to drive the pattern roll to roll accordingly, thereby switching the pattern displayed in the window.
[0046] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
[0047] The above examples are only preferred embodiments of the present application, and certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
