Description

Technical Field

[0001] This utility model relates to the field of electronic devices, specifically a touch-positioning learning machine panel input device. Background Technology

[0002] The existing touch input methods for learning machines on the market include 1-point touch, 16-point touch, 36-point touch, and other multi-point touch methods. Each point is a separate touch point. The principle is that the contact points on the input panel of the learning machine are arranged with conductive materials according to certain rules (such as...). Figure 1 As shown, a pre-made learning content card or a book with pre-made content is placed on the learning panel. When it comes into contact with the human body (finger), a capacitive signal is generated. This signal is then connected to the input port of the processor (content card recognition module) via a circuit. Each contact point requires a circuit connection, and each contact point consumes one input port of the processor (content card recognition module).

[0003] The existing touch input method used in learning machines on the market has the following drawbacks:

[0004] 1. Each contact point on the input panel of the learning machine must be connected to a corresponding input port of the processor. That is, the number of input ports consumed corresponds to the number of contact points, resulting in huge consumption of processor resources. The more contact points are arranged, the more input ports the processor needs, and the more expensive it is.

[0005] 2. Due to the limited number of ports on the processor, the number of input function contacts on the learning machine's input panel is limited, which is not conducive to the creation of learning content.

[0006] 3. Since each contact point is a separate working end fixed on the input panel of the learning machine, the position where the input content needs to be placed must be the same regardless of the learning content, content scenario, or multiple cards or books (e.g., ...). Figure 1 As shown, the touch input points for content creation must be set to fixed positions (pre-made learning content cards or a book of pre-made content), which severely restricts the creativity of content creation.

[0007] In summary, the existing contact points on the input panel of learning machines must be connected to a corresponding input port of the content card recognition module, and the content must be set in a fixed position. This is restrictive, costly, and needs to be improved. Utility Model Content

[0008] The purpose of this invention is to provide a touch-based positioning input device for a learning machine panel to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A touch-positioning learning machine panel input device includes a learning machine touch circuit board, which is mounted on the product front cover. The product front cover also has a content card recognition module, device function operation buttons, and a device main circuit board. A product bottom cover is provided at the bottom of the product front cover, and a power supply is provided on the product bottom cover.

[0011] As a further improvement of this utility model: a touch panel bracket and a content card are sequentially arranged on the side of the touch circuit board away from the product casing.

[0012] As a further improvement of this invention, a speaker is provided on the content card.

[0013] As a further aspect of the present invention: a touch circuit is provided on the touch circuit board, the touch circuit is arranged in multiple triangular lines, adjacent triangular lines share a common side, the triangular lines are opposite in direction to the adjacent triangular lines, and different triangular lines each lead to an output port to a different input port of the content card recognition module.

[0014] As a further embodiment of the present invention: the triangular lines are isosceles triangles.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model uses two adjacent triangular lines as a group. Different positions of one triangular line obtain signals of different intensities, and the signals of the other triangular line are compared. The two electrical signals are output to the content card recognition module, which calculates the specific touch position. This allows the number of triangular lines to be arranged according to the number of input ports of the content card recognition module. The corresponding number of triangular lines are arranged on the touch circuit board according to the size of the content card, realizing touch input at any position. This allows for the arrangement of touch points without quantity limitations in learning content, and also allows for the design and production of content and content scenes without being limited by the touch point position. Compared with single-point touch on the market, this technical solution can use the same content card recognition module and the same number of input ports to arrange any number of touch points at any position.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 2 A touch-based positioning learning machine panel input device includes a learning machine touch circuit board 3, which is mounted on a product faceplate 4. The product faceplate 4 is also equipped with a content card recognition module 5, device function operation buttons, and a device main circuit board 8. A product bottom shell 9 is provided at the bottom of the product faceplate 4, and a power supply 6 is provided on the product bottom shell 9.

[0023] In this embodiment: Please refer to Figure 2 The side of the touch circuit board 3 away from the product casing 4 is provided with a touch panel bracket 2 and a content card 1 in sequence.

[0024] When a user touches the content card 1 with their finger, the corresponding touch circuit board 3 is pressed, which sends a corresponding electrical signal to the content card recognition module 5. The content card recognition module 5 then sends a corresponding electrical signal to the device's main circuit board.

[0025] In this embodiment: Please refer to Figure 2 The content card 1 is equipped with a speaker 7.

[0026] After receiving the electrical signal, the main circuit board of the device drives the speaker 7 to work and output the content of the corresponding content card 1.

[0027] In this embodiment: Please refer to Figure 3 and Figure 4 The touch circuit board 3 is provided with touch circuit 31, which is arranged as multiple triangular lines. Adjacent triangular lines share a common side, and the triangular lines are opposite in direction to their adjacent triangular lines. Each of the different triangular lines leads to an output port to a different input port of the content card recognition module 5.

[0028] In this embodiment: Please refer to Figure 3 and Figure 4 The triangle lines are isosceles triangles.

[0029] by Figure 4 Taking point A as an example of a touch point, when a finger touches point A, the distance from point A on the touch line (all touch lines together constitute touch circuit 31) to the lower left output port IO2 is less than the distance from point A to the upper right output port IO3 (e.g., ...). Figure 4 As shown, the output port of the first triangle is IO1, the second is IO2, and so on. This causes the electrical signal to attenuate after passing through the touch lines, resulting in a larger signal at output port IO2 and a smaller signal at output port IO3. The content card recognition module 5, based on the received signals from IO2 and IO3, determines which touch line it is. Based on the strength of the transmitted electrical signals from IO2 and IO3, it determines the touch position, ultimately identifying position A. The content card recognition module 5 then outputs the learning content corresponding to position A. It should be noted that, theoretically, an unlimited number of learning contents can be set on a single touch line. However, considering the finger's touch range and the recognition accuracy of the content card recognition module 5, the actual number of corresponding learning contents that can be set is limited.

[0030] When touching lines that share a common side, two electrical signals are generated. Touching lines such as... Figure 4 As shown, when it is at the top or bottom, only one electrical signal will be generated.

[0031] Taking the touch line as the topmost line as an example, only the IO1 output port receives the electrical signal and transmits it to the content card recognition module 5. The content card recognition module 5 determines that the touch line is the topmost line based on the fact that only a single IO1 output port outputs a signal, and determines the specific location of the touch point based on the strength of the electrical signal.

[0032] The electrical signal corresponding to the location information identified by the content card recognition module 5 is transmitted to the main circuit board of the device. The main circuit board of the device drives the speaker 7 to work and outputs the content of the corresponding content card 1.

[0033] This invention uses two adjacent triangular lines as a group. Different positions of one triangular line receive signals of different intensities, and the signals of the other triangular line are compared. The two electrical signals are output to the content card recognition module 5, which calculates the specific touch position. The number of triangular lines can be arranged according to the number of input ports of the content card recognition module 5. The corresponding number of triangular lines are arranged on the touch circuit board 3 according to the area of ​​the content card 1, realizing touch input at any position. This allows for the arrangement of touch points without limitation in the number of touch points in the learning content, and also allows for the design and production of content and content scenes without being limited by the touch point position. Compared with single-point touch on the market, this technical solution can use the same content card recognition module 5 and the same number of input ports to arrange any number of touch points at any position.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
