Abstract
Description
Technical Field
[0001] This utility model relates to the field of learning equipment technology, and in particular to a learning machine. Background Technology
[0002] Currently, learning machines typically consist of an upper shell and a lower shell. The printed circuit board assembly (PCBA), which triggers commands through pressing, is usually located between the upper and lower shells. This ensures that the PCBA is not exposed on the surface of the learning machine, guaranteeing both aesthetics and safety. Since the PCBA has a certain thickness, there needs to be space between the upper and lower shells. Therefore, support pillars are usually provided between the upper and lower shells, and through holes are provided on the PCBA corresponding to these support pillars to fit the PCBA onto them, thus limiting its position. However, the location of these through holes prevents the placement of touch circuitry, forcing the touch circuitry to bypass the through holes. Consequently, when a press occurs at the support pillar, the corresponding function cannot be triggered, creating a trigger blind zone. Furthermore, the obstruction of the upper shell affects the propagation of pressing force to the PCBA, leading to low trigger accuracy. Utility Model Content
[0003] In view of the above problems, this utility model embodiment is proposed. The purpose of this utility model embodiment is to provide a learning machine with high press trigger accuracy and no trigger blind zone.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A learning machine, comprising:
[0006] The outer casing has a receiving space having an upward-facing opening;
[0007] A touch PCBA is housed within the receiving space and located at the opening. The bottom surface of the touch PCBA abuts against the bottom wall of the receiving space, and at least one circumferential edge of the top surface of the touch PCBA abuts against the top wall of the receiving space.
[0008] An insert plate is located at the opening and is removably mounted on the touch PCBA.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] Please refer to Figures 1-5 As shown in the figure, this application embodiment provides a learning machine, which includes a shell 1, a touch PCBA 2, and a plug-in board 4. The shell 1 has an accommodating space with an upward-facing opening 111. The touch PCBA 2 is housed in the accommodating space and covers the opening 111. The plug-in board 4 is detachably inserted into the plug-in port, so that the touch PCBA 2 can cover the plug-in board 4, thus eliminating the trigger blind zone. Furthermore, by pressing the plug-in board 4, the pressure is directly transmitted to the touch PCBA 2, with fewer pressure transmission paths, resulting in high trigger accuracy. The bottom surface of the touch PCBA 2 and the bottom wall of the accommodating space have mutually cooperating positioning structures, preventing the touch PCBA 2 from shifting. Moreover, the touch PCBA 2 does not need to have through holes, thus eliminating the trigger blind zone and allowing the circuitry on the touch PCBA 2 to be arranged fully and reasonably.
[0040] Further, please refer to Figures 1-5As shown, in some embodiments of this application, the positioning structure includes a positioning groove 31 and a positioning post 21 that cooperate with each other. The bottom surface of the touch PCBA2 and the bottom wall of the accommodating space are provided with a positioning groove 31 and a positioning post 21. The positioning groove 31 and the positioning post 21 match to position the touch PCBA2 in the accommodating space, thereby preventing the touch PCBA2 from moving around.
[0041] For ease of assembly, please refer to... Figures 1-5 As shown, in some embodiments of this application, the outer shell 1 includes an upper shell 11 and a lower shell 12 that are interlocked. The upper shell 11 has the aforementioned opening 111. Since the area of the opening 111 is smaller than the area of the insert plate 4, the outer shell 1 is designed as a split type to facilitate the assembly of the entire learning machine. A limiting plate 112 extends from the circumferential edge of the opening 111 toward the bottom wall of the accommodating space. A slot 113 is provided on one side of the limiting plate 112. The insert plate 4 has an insert block 42, which can be detachably inserted into the slot 113. The limiting plate 112 abuts against the peripheral edge of the insert plate 4 to limit the insertion plate 4 and prevent the insertion plate 4 from moving.
[0042] Since the insert plate 4 is detachable and can be inserted into the learning machine, please refer to... Figures 1-5 As shown, in some embodiments of this application, there is at least one insert plate 4, and different insert plates 4 have different contents. When different insert plates 4 are inserted into the learning machine, the learning content can be played according to the contents on the insert plate 4.
[0043] Understandably, since the content on different inserts 4 is different, there will definitely be different button frames. The difference in button frames refers to the difference in either the size or the position of the button frame. However, since a typical touch PCBA2 has through holes to fit onto the support pillar between the upper shell 11 and the lower shell 12, the press trigger area on the touch PCBA2 is fixed in order to avoid the touch blind zone at the through hole position. Therefore, the position and size of the button frames on different inserts 4 are also the same. This limits the richness of the content on different inserts 4. For example, the content on an insert A is a bookshelf with pictures of different books. Each book picture is a button frame. When a picture of a book is pressed, the corresponding book content will be read aloud. The other panel B contains information about pinyin, including three sections: initials, finals, and daily syllable recognition. Taking the initials section as an example, there are 23 buttons. Therefore, the size of these 23 buttons is much smaller than the size of the buttons corresponding to the pictures in the book on panel A. If these 23 buttons were the same size as the buttons corresponding to the pictures in the book on panel A, then the initials and finals sections could not be placed, which would limit the content of panel 4.
[0044] To solve the above problems, please refer to... Figures 1-5 As shown in the embodiments of this application, since the touch PCBA2 of this application has no pressing blind spots, pressing lines can be densely distributed in both radial and latitudinal directions, so that the positions of the touch PCBA2 covered by the insert plate 4 are densely covered with pressing lines. When different insert plates 4 are inserted into the learning machine, the learning machine's recognition function can be triggered to identify the corresponding insert plate 4, thereby controlling the pressing lines at different positions to form pressing areas corresponding to the pressing frames on the insert plate 4, thus ensuring that different insert plates 4 can have different content pressing frames.
[0045] If all edges of the insert plate 4 abut against the limiting plate 112, it will cause difficulty in removing the insert plate 4. Therefore, please refer to... Figures 1-5 As shown, in some embodiments of this application, the upper shell 11 is provided with a buckle groove 114 on one side of the opening 111 circumferentially, and the insert plate 4 is provided with a notch 41 that matches the buckle groove 114. The buckle groove 114 can accommodate a finger. When the insert plate 4 is removed from the learning machine, the finger can be placed in the buckle groove 114 and abut against the edge of the notch 41, and a force is applied to the edge of the notch 41 toward the side away from the lower shell 12. Then the side of the insert plate 4 away from the insert block 42 will be lifted and disengaged, thereby enabling the insert block 42 to be pulled out of the slot, thereby realizing the removal of the insert plate 4.
[0046] Of course, in other embodiments, the insert plate 4 may not be detachably mounted to the learning machine through the opening 111. Alternatively, the side of the outer casing 1 may have an insertion port, with the side containing the insertion port facing the side containing the slot opening 113. A slide rail is formed where the insertion port is larger than the opening 111. The two sides of the insert plate 4 slide along the slide rail until the insert block 42 is inserted into the slot opening 113, thus installing the insert plate 4. A push-pull block is provided on the side of the insert plate 4 facing away from the insert block 42. When the insert plate 4 needs to be removed, a pulling force can be applied to the push-pull block to move it away from the outer casing 1 to remove the insert plate 4.
[0047] In some embodiments of this application, please refer to Figures 1-5 As shown, the learning machine also includes a support plate 3. The bottom surface of the support plate 3 abuts against the lower shell 12, and the top surface abuts against the upper shell 11, forming an accommodating space with the upper shell 11. The touch PCBA2 abuts against the support plate 3. The support plate 3 not only provides better support for the touch PCBA2, but also strengthens the structural strength of the learning machine.
[0048] Further, please refer to Figures 1-5As shown in some embodiments of this application, the support plate 3 has a receiving groove 32 on its side away from the lower shell 12. The touch PCBA2 is located in the receiving groove 32 and is flush with the top surface of the periphery of the receiving groove 32. In this way, when the upper shell 11 is subjected to pressure, the pressure will not only act on the touch PCBA2 board, but the support plate 3 can also withstand a certain amount of pressure, thereby preventing the touch PCBA2 from being crushed due to excessive pressure, and also providing flat support for the insert plate 4 to prevent it from tilting.
[0049] Please refer to Figures 1-5 As shown, in some embodiments of this application, the bottom surface of the support plate 3 and the top surface of the lower shell 12 are provided with an abutment groove 33, and the other is provided with an abutment post 121. The abutment post 121 and the abutment groove 33 are engaged to limit the position of the support plate 3 on the lower shell 12 and prevent the support plate 3 from moving.
[0050] Because the touch PCBA2 board has numerous circuits, exposing them directly to the outside world through opening 111 would not only be unsightly but also pose a risk of damage. Therefore, please refer to... Figures 1-5 As shown, in some embodiments of this application, the learning machine also includes a protective element 5, which covers the top surface of the touch PCBA2. The protective element 5 can be a flexible protective film, which not only does not hinder the transmission of pressure but also protects the touch PCBA2 from external interference.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
