In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description, and cannot be understood as indicating or implying relative importance.
[0025] Please refer to Figures 1 to 3 , Figure 1 which is the front view of the stylus pen 2 shown in an exemplary embodiment of the present application. Figure 2 is Figure 1 the top view of the stylus pen 2 shown in Figure 3 is Figure 1 the bottom view of the stylus pen 2 shown in
[0026] The present application provides a stylus pen 2 which can be paired with the learning machine body 1 for writing or for touching the screen of the learning machine body 1.
[0027] The stylus pen 2 includes a pen barrel 21, a wiping head 22 and a stylus pen core. The stylus pen core is disposed inside the pen barrel 21, and the tip 23 of the stylus pen core extends out from the lower end of the pen barrel 21. The wiping head 22 is disposed at the top of the pen barrel 21, and the wiping head 22 is used for erasing the writing traces on the display screen.
[0028] The pen barrel 21 includes a main body section 210 and a tapered section 211 connected to the lowermost end of the main body section 210, and the tip 23 extends out from the tapered section 211. The main body section 210 is arranged as a constant cross-section structure with equal cross-sections everywhere, and the cross-sectional area of the tapered section 211 gradually decreases from top to bottom. When projected orthogonally along the length direction of the pen barrel 21 and from top to bottom ( Figure 1 the Z direction in Figure 2 ), the shape of the outer contour line of the main body section 210 is an ellipse (please refer to
[0029] ). Here, the "cross-section" refers to the section obtained by a plane perpendicular to the length direction of the stylus pen 2.
[0030] According to the above description, with the main body section 210 having an elliptical cross-section, the stylus pen 2 is not likely to roll when placed on a table. Moreover, since the ellipse is relatively flatter, the comfort during holding is better and it is not easy to slip when held in the hand. The main body section 210 and the tapered section 211 can be arranged as an integral structure.
[0030] In one embodiment, as shown in Figure 2 , the range of the ratio of the major axis dimension W to the minor axis dimension B of the ellipse is 1.1 to 1.2. In this way, by selecting the major axis and the minor axis under this corresponding relationship, the flatness of the ellipse is better, neither too flat nor too close to a circle. For example, the ratio of the major axis dimension W to the minor axis dimension B can be 1.1, 1.12, 1.14, 1.16, 1.18, 1.2, but not limited thereto. In a specific embodiment, the major axis dimension W of the ellipse is 10 ± 0.2 mm, and the minor axis dimension B is 8.6 ± 0.2 mm.
[0031] In one embodiment, the outer surface of the pen holder 21 is set to a matte finish. The matte finish has a lower glossiness and smoothness, and is relatively less likely to slip when held. The pen holder 21 can be processed by an injection molding process.
[0032] In one embodiment, the outer surface of the wiping head 22 is set to a shiny finish. With this setting, when the wiping head 22 comes into frequent contact with the screen of the learning and practice machine body 1, the shiny surface will become brighter and brighter as it is rubbed, and will not cause scratches on the wiping head 22, ensuring the appearance and smoothness of the wiping head 22. The housing of the wiping head 22 can be processed by an injection molding process, and the inner wall of the mold is polished to form a shiny surface on the housing. Of course, the outer surface of the wiping head 22 can also be directly polished.
[0033] In one embodiment, the length dimension of the wiping head 22 should not be too long. The length of the wiping head 22 can account for 1 / 25 of the total length of the stylus 2. In a specific embodiment, the total length of the stylus 2 is 148 ± 2 mm, and the length of the wiping head 22 is 6.5 ± 0.5 mm.
[0034] In one embodiment, to ensure the consistency of the overall structure of the stylus 2, the outer contour line of the wiping head in the positive projection along the length direction of the pen holder 21 and from top to bottom ( Figure 1 the Z direction in the figure) coincides with the ellipse, so that the shape of the stylus 2 is more concise and has better unity.
[0035] In one embodiment, the wiping head 22 is movable along the length direction of the pen holder 21, so as to meet the electromagnetic requirements during the wiping process. The moving displacement of the wiping head 22 can be set to less than 1 mm, for example, 0.6 mm. It should be noted that the wiping head 22 is set to automatically reset after being pressed.
[0036] In one embodiment, the main body section 210 includes an upper section 210a and a lower section 210b that are fixedly connected. The wiping head 22 is installed at the upper end of the upper section 210a, and the tapered section 211 is connected to the lower end of the lower section 210b. With this setting, the main body section 210 is in a segmented form. Before assembly, the upper section 210a and the lower section 210b are separately arranged, and after the pen tip is inserted, the upper section 210a and the lower section 210b are fixed to meet the requirements of the assembly process.
[0037] In one embodiment, as Figure 1 shown, the range of the ratio of the length of the upper section 210a to the length of the pen holder 21 is 0.2 to 0.3, as long as it meets the requirements for assembling the pen tip. In one embodiment, the length of the upper section 210a is 30 ± 2 mm, and the length of the pen holder 21 is 142 ± 2 mm.

[0040] In one embodiment, the learning and practice machine body 1 includes a display area 101 and a non-display area 102 on the front of the fuselage. The non-display area 102 is provided with a storage groove 104, and the stylus 2 is stored in the storage groove 104. The storage groove 104 can provide a storage space for the stylus 2, and at least part of the stylus 2 can be located in the storage groove 104, thereby occupying less space outside the learning and practice machine body 1. The shape of the storage groove 104 can be adapted to the shape of the stylus 2, and the storage groove 104 can be set as a 1 / 2 elliptical groove. The stylus 2 can also be held in the storage groove 104 by magnetic attraction, but not limited to this.
[0041] Combined with Figure 4 and Figure 5 , the non-display area 102 includes a right non-display area 102y provided on the right side of the display area 101 and located at the right edge of the front of the fuselage. The right non-display area 102y is provided with the arc transition surface 103, and the arc transition surface 103 extends from the side close to the display area 101 to the outermost edge on the right side of the front of the fuselage. The storage groove 104 is provided on the arc transition surface 103.
[0042] Please refer to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the assembly 10, in which the protective cover 3 is in the unfolded state. Figure 7 is another schematic diagram of the assembly 10, in which the protective cover 3 is in the folded state.
[0043] The present application also provides an assembly 10 including a learning and practice machine and a protective cover 3. The assembly 10 includes the above-mentioned learning and practice machine and the protective cover 3.
[0044] The protective cover 3 is configured to have an unfolded state and a folded state. In the unfolded state, the front 14 and the back 15 of the fuselage of the learning and practice machine can be covered by the protective cover 3. In the folded state, the learning and practice machine can be tilted and supported by the protective cover 3.
