[0017] Figure 2 is a schematic structural diagram of another embodiment of the electronic device protective case of the present utility model.
Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be described in conjunction with the drawings of the present utility model.
[0019] Please refer to Figure 1 , the present utility model provides an electronic device protective case 100. Specifically, the electronic device protective case 100 is adapted to electronic products such as mobile phones and tablet computers. The electronic device protective case 100 includes a main body portion 10 and a frame 30 protruding from the edge of the main body portion.
[0020] Among them, an annular magnetic member 21, a first magnetic block 22, and a second magnetic block 23 are provided inside the main body portion 10. Preferably, the linear distance D1 between the edge of the first magnetic block 22 close to the second magnetic block 23 and the edge of the second magnetic block 23 close to the first magnetic block 22 ranges from 15 mm to 19 mm; the distance D2 between the first magnetic block 22 and the second magnetic block 23 from the first width side 31 of the frame 30 ranges from 3 mm to 10 mm; the distance between the vertical median line between the first magnetic block 22 and the second magnetic block 23 and the first central axis L1 of the annular magnetic member does not exceed 3 mm. In this way, it is ensured that the first magnetic block 22 and the second magnetic block 23 are basically symmetrically arranged on both sides of the central axis of the annular magnetic member 21; and the magnetic attraction force between the first magnetic block 22 and the second magnetic block 23 is concentrated. Specifically, the first width side of the frame 30 is the width side of the frame 30 close to the first magnetic block 22 and the second magnetic block 23.
[0021] Furthermore, the distance D3 from the connection line between the side of the first magnetic block 22 close to the annular magnetic member 21 and the side of the second magnetic block 23 close to the annular magnetic member 21 to the second central axis L2 of the annular magnetic member 21 ranges from 59 mm to 72 mm. Or, the distance from the edge of any one of the first magnetic block 22 and the second magnetic block 23 close to the annular magnetic member 21 to the second central axis L2 of the annular magnetic member 21 ranges from 59 mm to 72 mm. In this way, the distance between the first magnetic block 22, the second magnetic block 23 and the annular magnetic member 21 can maintain the concentration of the magnetic attraction force. Preferably, the side edges of the first magnetic block 22 and the second magnetic block 23 do not exceed the outer edge of the annular magnetic member 21 respectively.
[0022] The shapes of the first magnetic block 22 and the second magnetic block 23 can be rectangular, triangular or trapezoidal. In this embodiment, both the first magnetic block 22 and the second magnetic block 23 are rectangular magnets. The width range of the rectangular magnet is 5 mm to 9 mm, and the length range of the rectangular magnet is 8 mm to 12 mm.
[0023] Please refer to Figure 2 , in this embodiment, a tail magnetic block 25 is further provided inside the main body portion 10. Preferably, the central axis of the tail magnetic block 25 is collinear with the first central axis L1 of the annular magnetic member 21. The length range of the tail magnetic block 25 is 19 ± 0.5 mm, and the width range is 6 ± 0.2 mm. The distance range between the center of the tail magnetic block 25 and the center of the annular magnetic member 21 is 39 ± 1 mm. In this way, the tail magnetic block 25 is closer to the annular magnetic member 21 than the first magnetic block 22 and the second magnetic block 23, enhancing the magnetic attraction force and the positioning ability.
[0024] Preferably, the thicknesses of the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 are all 0.4 ± 0.1 mm. Moreover, the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 are all made of neodymium iron boron magnets. In this way, the overall thinness and lightness of the magnet and the protective case are ensured, and sufficient magnetic attraction is ensured.
[0025] In another preferred embodiment, a groove is further formed on the inner side of the main body portion 10. The annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 are all arranged in this groove and do not protrude from the inner surface of the main body portion 10.
[0026] Furthermore, a light-shielding adhesive film 28 is provided between the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, the tail magnetic block 25 and the bottom of the groove. For example: the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, the tail magnetic block 25 and the light-shielding adhesive film 28 form a magnet assembly; the light-shielding adhesive film 28 covers the bottom of the groove; thereby covering the gap between the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, the tail magnetic block 25 and the groove, achieving the effect of light shielding. Specifically, the thicknesses of the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 are all 0.4 ± 0.1 mm, and the thickness of the light-shielding adhesive film 28 is 0.1 ± 0.05 mm. The outer edges of the light-shielding adhesive film 28 protrude at least 1 mm from the outer edges of the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 respectively. In this embodiment, the total thickness of the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 after the light-shielding adhesive film 28 is provided is basically the same as the groove depth of this groove, so that it still does not protrude from the inner surface of the main body portion 10.
[0027] Furthermore, a filling film for increasing flatness is provided on the outer surfaces of the annular magnetic member 21, the first magnetic block 22, the second magnetic block 23, and the tail magnetic block 25 and the groove. Preferably, this filling film is transparent; to maintain the aesthetic appearance of the electronic device protective case 100.
