Technical Field

[0001] The utility model relates to the technical field of locators, in particular to a waterproof silicone sealing ring and a tracker with the same. Background Art

[0002] Existing Bluetooth trackers are already widely used in the market, whether they are used to find keys, pets, or track luggage and important items, they have brought a lot of convenience to our lives. However, despite the excellent performance of these trackers in terms of functionality and practicality, they have obvious shortcomings in terms of waterproof performance.

[0003] Specifically, the sealing effect of many Bluetooth trackers is not ideal. This is mainly reflected in the seams of their shells, which are often not sealed tightly due to problems with the process or materials. Once it rains or is accidentally placed in a humid environment, moisture can easily penetrate into the interior through these tiny gaps. In addition, some Bluetooth trackers have compromised on waterproofing in pursuit of a thin and light design, resulting in a lack of waterproofing capabilities.

[0004] Once the Bluetooth tracker is soaked in water, it may not only damage its internal electronic components, thus affecting normal use, but may even cause safety problems such as short circuits. In addition, prolonged exposure to moisture may also cause corrosion to the tracker's casing, shortening its service life.

[0005] Therefore, for existing Bluetooth trackers, improving their waterproof performance has become an urgent problem to be solved. At present, in order to solve the waterproof problem, a gasket is usually sandwiched between the upper cover and the lower cover of the Bluetooth tracker for sealing. If the upper cover and the lower cover are not pressed in place during installation, water seepage will still occur. Utility Model Content
