[0031] Please refer to Figures 1 to 3 , Figure 1 is a front view of the protective sleeve 3 shown in an exemplary embodiment of the present application. Figure 2 is Figure 1 is a schematic view of the protective sleeve 3 in a folded state shown in Figure 3 is Figure 1 is a schematic view of the protective sleeve 3 in a folded state shown in

[0032] The present application provides a protective sleeve 3 for protecting electronic products, including but not limited to training machines.

[0033] The protective sleeve 3 includes an upper guard plate 31, a lower guard plate 32, and a flexible part 33 connecting the upper guard plate 31 and the lower guard plate 32. The flexible part 33 can be bent, so that the upper guard plate 31 and the lower guard plate 32 can be relatively flipped. The specific material of the flexible part 33 is not limited.

[0034] The upper guard plate 31 has an upper crease 310 extending from the top to the bottom, and the upper guard plate 31 can be bent at the upper crease 310. The lower guard plate 32 has a lower crease 320 extending from the top to the bottom, and the lower guard plate 32 can be bent at the lower crease 320. Figure 1 The arrows in the diagram indicate the "top" and "bottom" directions of the upper guard plate 31 and the lower guard plate 32.

[0035] The protective sleeve 3 has a covered state for covering electronic products and a folded state for supporting electronic products. In the covered state, the protective sleeve 3 is bent at the flexible part 33, and the upper protective plate 31 is located above the lower protective plate 32. The electronic product can be placed between the upper protective plate 31 and the lower protective plate 32, thereby protecting the electronic product. In the folded state, the protective sleeve 3 is bent at the upper crease 310, the lower crease 320, and the flexible part 33, forming a hollow trihedral structure, thereby supporting the electronic product and facilitating user use. The terms "upper," "lower," "left," and "right" used in this document refer to the orientation of the various parts of the protective sleeve 3 in the covered state. Figure 2 As indicated by the arrows in the middle.

[0036] As described above, the protective case 3 can protect and support electronic products. In its covered state, the upper protective plate 31 covers the front of the electronic product, and the lower protective plate 32 covers the back, reducing the risk of damage. In its folded state, the back of the electronic product rests against one side of the three-sided protective case 3, making it convenient for the user. The protective case 3 has a simple structure and provides reliable support.

[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the upper protective plate 31 includes a left upper protective plate 31a located to the left of the upper crease 310 and a right upper protective plate 31b located to the right of the upper crease 310. In the left-right direction, the size of the left upper protective plate 31a is larger than the size of the right upper protective plate 31b. The inner surface of the left upper protective plate 31a serves as the bottom surface A of the trihedral structure. This arrangement makes the side length of the bottom surface A of the trihedral structure relatively large, resulting in better support stability. The right upper protective plate 31b is located on one side B of the trihedral structure used to support the electronic product.

[0038] In one embodiment, the lower guard plate 32 includes a lower guard plate left plate 32a located to the left of the lower crease 320 and a lower guard plate right plate 32b located to the right of the lower crease 320, and the flexible part 33 connects the upper guard plate left plate 31a and the lower guard plate left plate 32a.

[0039] The lower right plate 32b and the upper right plate 31b are located on the same side of the three-sided structure, i.e., side B. The lower right plate 32b and the upper right plate 31b overlap each other and are relatively fixed, and the fixing manner is not limited, including but not limited to clamping and magnetic attraction. The lower left plate 32a is located on the other side of the three-sided structure, and the inner surface of the lower left plate 32a serves as another side C of the three-sided structure. In this way, the lower right plate 32b and the upper right plate 31b are located on the same side of the three-sided structure, and the side is a double-layer plate that overlaps and is relatively fixed, which is more advantageous for supporting the electronic product.

[0040] In an embodiment, the lower right plate 32b is located on the outside of the upper right plate 31b, and the upper right plate 31b is attached to the outer surface of the lower right plate 32b. The inner surface of the lower right plate 32b serves as side B and is used to contact the electronic product. In this way, during folding, the lower right plate 32b can be kept stationary, and the rest of the protective sleeve 3 can be flipped to the left by one turn and bent in a predetermined direction, which facilitates the folding of the protective sleeve 3 and is more convenient to operate.

[0041] In an embodiment, the upper left plate 31a and the lower left plate 32a are equal in size in the left-right direction, and the upper right plate 31b and the lower right plate 32b are equal in size in the left-right direction. In this way, the size of the lower right plate 32b is also smaller than that of the lower left plate 32a. For the three-sided structure, the upper left plate 31a on side A and the lower left plate 32a on side C have equal side lengths, and the upper right plate 31b and the lower right plate 32b on side B have a relatively small side length. In this way, side B can be inclined to the left relative to the vertical plane, so that the electronic product supported on side B also tilts backward, which is convenient for the user to operate. Figure 3 In the placement state shown, the side length of side B where the lower right plate 32b and the upper right plate 31b are located is relatively small, so side B can be inclined backward relative to the vertical plane. In this way, the electronic product supported on side B also tilts backward, which is convenient for the user to operate. In an embodiment, the angle of side B relative to the vertical plane can be set to 30°±5°.

[0042] In an embodiment, the upper plate 31 and the lower plate 32 have the same shape and size. In the left-right direction, the size of the upper right plate 31b is less than 1 / 2 of the total size of the upper plate 31. In this embodiment, the ratio of the size of the upper right plate 31b to the total size of the upper plate 31 is in the range of 0.4-0.45, for example, the ratio of the two can be 0.4, 0.41, 0.42, 0.43, 0.44, or 0.45.

[0043] In one specific embodiment, the size of the upper guard plate 31 in the left-right direction is 204±5mm, and the size of the upper guard plate right plate 31b is 88±2mm. The size of the lower guard plate 32 is the same as that of the upper guard plate 31.

[0044] In one embodiment, one of the upper guard plate right plate 31b and the lower guard plate right plate 32b is provided with a magnetic member, and the other is provided with a magnetic matching member (not shown). In the folded state, the magnetic member and the magnetic matching member are adsorbed and fixed. The magnetic adsorption fixing mode is simple and reliable. It should be noted that one of the magnetic member and the magnetic matching member can be a permanent magnet, and the other is a magnetic conductor. Alternatively, the magnetic member and the magnetic matching member can also be two permanent magnets with opposite polarities.

[0045] In one embodiment, as shown in Figure 1 , the inner surface of the upper guard plate right plate 31b is also provided with a avoiding slot 311 for avoiding the stylus. The shape and size of the avoiding slot 311 are set to match the shape and size of the stylus. In the embodiment shown in Figure 2 , the outer surface of the upper guard plate right plate 31b is formed with a convex 312 opposite the part of the avoiding slot 311. The shape of the avoiding slot 311 is substantially the same as that of the convex 312, and the depth of the concave of the avoiding slot 311 is substantially equal to the height of the convex of the convex 312.

[0046] In one embodiment, as shown in Figure 2 , the right end edge of the upper guard plate right plate 31b is also provided with a circular arc transition section 313 extending from left to right, and the outer surface and the inner surface of the circular arc transition section 313 are both circular arc surfaces. The circular arc transition section 313 is set to match the front profile of the electronic product, so that the protective sleeve 3 is more closely matched with the shape of the electronic product, improving the feeling of being covered by the protective sleeve 3.

[0047] Please refer to Figure 4 and Figure 5 , Figure 4 for the schematic view of the combination 10, wherein the protective sleeve 3 is in the covering state. Figure 5 for another schematic view of the combination 10, wherein the protective sleeve 3 is in the folded state.

[0048] The present application also provides a combination 10 comprising a protective sleeve 3 and a training machine, which comprises a training machine and a protective sleeve 3. On the one hand, the protective sleeve 3 can protect the training machine from damage, and on the other hand, it can provide support when the user uses the training machine, avoiding the user holding the training machine.

[0049] Please refer to Figure 6 and Figure 7 , Figure 6 for the front view of the training machine. Figure 7A bottom view of the learning and practice machine.

[0050] In one embodiment, the learning and training device includes a main body 1 and a stylus 2. The front of the main body 1 has a display area 101 and a non-display area 102. The non-display area 102 includes a right non-display area 102y located to the right of the display area 101 and at the right edge of the front of the main body. The learning and training device is supported and attached to the protective case 3 with the right non-display area 102y at the bottom. With the right non-display area 102y at the bottom and the display area 101 above it, the display area 101 is roughly level with the user's line of sight in the height direction, improving the user experience.

[0051] like Figure 7 As shown, the arc transition surface 103 is provided in the non-display area 102y on the right side. The arc transition surface 103 extends from the side near the display area 101 to the outermost edge of the right side of the front of the device. In the covered state, the arc transition section 313 at the right edge of the upper protective plate 31b can fit with the arc transition surface 103, resulting in a better covering effect.

[0052] In one embodiment, the learning machine further includes a stylus 2, which is assembled and stored in the non-display area 102 of the learning machine. Specifically, a storage groove 104 is provided on the arc transition surface 103 of the right non-display area 102y, and the stylus 2 is stored in the storage groove 104. The inner surface of the right plate 31b of the upper guard plate is also provided with a clearance groove 311, which is directly opposite to the storage groove 104. The stylus 2 is accommodated in the clearance groove 311 and the storage groove 104.
