[0035] Currently, electronic products used outdoors are usually equipped with protective cases. The waterproofing of the protective case is usually achieved through the overlap between the case and the cover. Due to the limitations of the manufacturing process, the existing protective cases and covers cannot make a completely tight contact, which will result in gaps between the case and the cover and lose the waterproofing effect.
[0036] To address the above problems, this utility model provides an electronic product that solves them. The electronic product includes electronic components and a waterproof protective case. Please refer to [link / reference]. Figures 1 to 5 The waterproof protective shell 10 includes a first shell 100 and a second shell 200, which form an installation cavity, and electronic components are disposed in the installation cavity.
[0037] In this embodiment, the electronic components can be PCBAs, etc. By placing the electronic components in the mounting cavities of the first housing 100 and the second housing 200, the first housing 100 and the second housing 200 can effectively waterproof the device.
[0038] In detail, the first housing 100 includes a first base plate 110 and a first side plate 120 connected to each other. One end of the first side plate 120 is connected to the first base plate 110, and the other end is provided with a first mating surface 121. A first rib 122 protrudes from the first mating surface 121. The second housing 200 includes a second base plate 210 and a second side plate 220 connected to each other. One end of the second side plate 220 is connected to the second base plate 210, and the other end is provided with a second mating surface 221. A second rib 222 protrudes from the second mating surface 221. The first base plate 110, the first side plate 120, the second base plate 210, and the second side plate 220 together form an installation cavity.
[0039] When the first housing 100 and the second housing 200 are connected, at least a portion of the first rib 122 abuts against the second mating surface 221, or at least a portion of the second rib 222 abuts against the first mating surface 121. That is, on the same cross section of the first housing 100 and the second housing 200, either the first rib 122 abuts against the second mating surface 221, or the second rib 222 abuts against the first mating surface 121.
[0040] In this embodiment, by providing a first rib 122 on the first mating surface 121 of the first housing 100 and a second rib 222 on the second mating surface 221 of the second housing 200, and by ensuring that at least a portion of the first rib 122 abuts against the second mating surface 221 and at least a portion of the second rib 222 abuts against the first mating surface 121, the waterproof function is effectively achieved through the first rib 122 or the second rib 222. In addition, by setting the first rib 122 and the second rib 222 at intervals, gaps can be avoided caused by the first rib 122 and the second rib 222 being squeezed against each other due to process errors, further ensuring the waterproof performance of the waterproof protective shell 10.
[0041] Furthermore, the inventors also discovered in actual use that if the contact area between the rib and the mating surface is designed to be too small, the rib will have gaps due to the limitations of the manufacturing process, resulting in a loss of waterproof effect; while if the contact area between the rib and the mating surface is too large, the surface tension of water will cause water to be sucked into the protective shell, thus failing to achieve the protective effect.
[0042] Therefore, in order to solve the problem that insufficient overlapping rib size or excessive contact surface size can cause water to enter the protective shell and further lead to the failure of waterproofing tests, it is necessary to design the contact surface between the rib and the mating surface appropriately.
[0043] Therefore, the gap between the first rib 122 and the second rib 222 is G, which is greater than or equal to 0.05 mm.
[0044] In this embodiment, by making the gap between the first rib 122 and the second rib 222 greater than or equal to 0.05mm, the gap between the first rib 122 and the second rib 222 is not too small, which would cause the first rib 122 and the second rib 222 to squeeze each other and create a gap, thus ensuring the waterproof performance of the waterproof protective shell 10.
[0045] For example, the gap between the first rib 122 and the second rib 222 can be 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm and 0.10mm, etc., but it is not limited to these. The gap between the first rib 122 and the second rib 222 can also be other values, which are not specifically limited here.
[0046] Furthermore, the width of the first rib 122 is T1, and T1 is greater than or equal to 0.5 mm.
[0047] In this embodiment, by making the width of the first rib 122 greater than or equal to 0.5mm, the width of the first rib 122 is prevented from being too small to achieve a waterproof effect.
[0048] For example, the width of the first rib 122 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1.0mm, etc. Of course, it is not limited to this. The width of the first rib 122 can also be other values, which are not specifically limited here.
[0049] In addition, the height H1 of the first rib 122 is greater than or equal to 0.5 mm.
[0050] In this embodiment, by making the height of the first rib 122 greater than or equal to 0.5mm, the height of the first rib 122 is prevented from being too low, which would cause the first rib 122 to fail to abut against the second mating surface 221 and create a gap, thus ensuring the waterproof performance of the waterproof protective shell 10.
[0051] For example, the height of the first rib 122 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm, etc. Of course, it is not limited to this, and the height of the first rib 122 can also be other values, which are not specifically limited here.
[0052] Similarly, the width of the second rib 222 is T2, which is greater than or equal to 0.5 mm.
[0053] By ensuring that the width of the second rib 222 is greater than or equal to 0.5mm, the width of the second rib 222 is prevented from being too small to provide waterproofing.
[0054] For example, the width of the second rib 222 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1.0mm, etc., but it is not limited to these. The width of the second rib 222 can also be other values, which are not specifically limited here.
[0055] In addition, the height of the second rib 222 is H2, which is greater than or equal to 0.5 mm.
[0056] In this embodiment, by making the height of the second rib 222 greater than or equal to 0.5mm, the height of the second rib 222 is prevented from being too low, which would cause the second rib 222 to fail to abut against the first mating surface 121 and create a gap, thus ensuring the waterproof performance of the waterproof protective shell 10.
[0057] For example, the height of the second rib 222 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1.0mm, etc. Of course, it is not limited to this. The height of the second rib 222 can also be other values, which are not specifically limited here.
[0058] Furthermore, the first mating surface 121 is provided with a first mounting portion 123, and the first rib 122 is provided on the inner side of the first mounting portion 123;
[0059] The second mating surface 221 is provided with a second mounting part 223, and the second rib 222 is provided on the outside of the second mounting part 223;
[0060] The first mounting part 123 and the second mounting part 223 are arranged opposite to each other and connected by fasteners, and a clearance space 130 is formed between the first rib 122 and the second rib 222.
[0061] In other words, when the first housing 100 and the second housing 200 are in the installed state, the first mounting part 123 and the second mounting part 223 are arranged opposite to each other and are both located between the first rib 122 and the second rib 222. The fasteners can be bolts, screws and other components. Therefore, by connecting the first mounting part 123 and the second mounting part 223 with fasteners, the first housing 100 and the second housing 200 can be stably connected together.
[0062] It should be noted that at the clearance space 130 formed by the first rib 122 and the second rib 222, the width of the portion of the first rib 122 that abuts against the second mating surface 221 is less than or equal to 3mm, and the width of the portion of the second rib 222 that abuts against the first mating surface 121 is less than or equal to 3mm.
[0063] In other words, at the formed clearance space 130, the first rib 122 abuts against the second mating surface 221, and the second rib 222 is spaced apart from the first contact surface; or the second rib 222 abuts against the first mating surface 121. The first rib 122 and the second mating surface 221 are spaced apart, thereby reducing the contact area between the first housing 100 and the second housing 200.
[0064] In detail, both the first housing 100 and the second housing 200 are provided with four mounting parts. The four first mounting parts 123 of the first housing 100 are provided in a one-to-one correspondence with the four second mounting parts 223 of the second housing 200, thereby ensuring that the first housing 100 and the second housing 200 are firmly connected.
[0065] In summary, this utility model provides a waterproof protective shell 10 and an electronic product. By providing a first rib 122 on the first mating surface 121 of the first shell 100 and a second rib 222 on the second mating surface 221 of the second shell 200, and by ensuring that at least a portion of the first rib 122 abuts against the second mating surface 221 and at least a portion of the second rib 222 abuts against the first mating surface 121, the waterproof function is effectively achieved through the first rib 122 or the second rib 222. Furthermore, by spacing the first rib 122 and the second rib 222 apart, gaps can be avoided caused by the first rib 122 and the second rib 222 being squeezed against each other due to manufacturing errors, further ensuring the waterproof performance of the waterproof protective shell 10.

Various modifications and variations can be made to this utility model by those skilled in the art.
