Description
TECHNICAL FIELD
[0001] The application belongs to the field of GPS positioning technology application, and particularly relates to a waterproof GPS positioning device suitable for water area work. BACKGROUND
[0002] Since the development of the global satellite positioning system (GPS) in the 1970s, it has been widely used in positioning and navigation on land, in the air and in some water areas. In the land environment, GPS has played an important role in the fields of transportation, topographic mapping, precision agriculture, disaster prevention and mitigation, etc. due to its high precision, all-weather and real-time advantages. However, when GPS technology is applied to marine environments, especially underwater operations, its limitations become apparent.
[0003] Specifically, the key hardware components of GPS equipment, such as the shell, interface and circuit board, are not specially designed for waterproofing, moisture-proofing and temperature changes in marine environments with high humidity, high salinity and drastic temperature changes. The complexity of the marine environment, including continuous tidal surges, wave impacts and other physical factors, further exacerbates the challenges of waterproof performance of GPS equipment. These factors not only may cause water ingress inside the device, but also may cause corrosion of the circuit board, interface failure and a series of problems, thereby seriously reducing the reliability and stability of the GPS equipment.
[0004] Therefore, the use of existing GPS equipment in marine environments has been severely limited, especially in underwater operation equipment that requires high-precision positioning and navigation, and this limitation is particularly prominent. CONTENT OF THE INVENTION

[0008] The shell assembly comprises a shell body, an upper end cover and a bottom cover connected to the upper and lower ends of the shell body, and the upper end cover is made of a non-metallic material.
[0009] Furthermore, the outer casing assembly also includes a pressure cap, and a first limiting structure is provided inside the casing.

The bottom end of the upper end cap abuts against the top end of the first limiting structure, and its periphery simultaneously cooperates with and abuts against the edge of the through hole of the pressure cap and the inner wall of the casing.
[0010] Preferably, the first limiting structure has a first limiting groove on the side facing the upper end cover, and the first sealing member is accommodated in the first limiting groove and is interference-fitted with the first limiting groove.

[0012] Preferably, the filling cap is made of a non-metallic material.
[0013] Furthermore, the waterproof connector is installed on the bottom cover, and the bottom cover has a through hole for installing the waterproof connector, and the waterproof connector is threadedly connected to the through hole.
[0014] Furthermore, a second limiting structure is provided on the outer periphery of the waterproof connector, and the top end of the second limiting structure abuts against the bottom of the bottom cover;
[0015] The second limiting structure has a second limiting groove on the side facing the bottom cover, and the second limiting groove accommodates a third sealing element and is interference-fitted with the third sealing element.
[0016] Preferably, the upper end cover, the first sealing element, and the positioning chip are arranged coaxially, and the waterproof connector is arranged eccentrically.
[0017] Furthermore, the second seal is located between the bottom cover and the housing, and the first fastener passes through the bottom cover, the second seal, and is detachably connected to the housing.
[0018] Furthermore, the bottom cover is detachably connected to the positioning chip via a second fastener made of insulating material.
[0019] The embodiments of this application provide a waterproof GPS positioning device suitable for operation in water areas, which has at least the following beneficial effects:
[0020] This application ensures the waterproof effect of the positioning device through the cooperation of the outer shell assembly, positioning chip, waterproof connector, first seal and second seal. The positioning device can be continuously installed on the underwater operation equipment, avoiding the impact on the positioning effect and operation efficiency of the underwater operation equipment due to repeated installation of the positioning device.

[0030] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.
[0031] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. Unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.
[0032] Furthermore, in the description of the embodiments of this application, various components on the drawings have been enlarged or reduced for ease of understanding, but this is not intended to limit the scope of protection of this application.
[0033] This application provides a waterproof GPS positioning device (hereinafter referred to as positioning device) suitable for working in water areas. The positioning device can be connected to underwater work equipment, which not only ensures the waterproof effect and position accuracy underwater and after surfacing, but also avoids the impact on the positioning effect and work efficiency of underwater work equipment due to repeated installation of the positioning device. Moreover, when returning to the surface after underwater work is completed, the underwater work equipment can be quickly and accurately located through the device.
[0034] Specifically, Figures 1-3 The overall structural diagram, exploded view, and cross-sectional view of the positioning device are shown respectively, as follows: Figures 1-3 As shown, the positioning device includes a housing assembly 1, a first seal 2, a second seal 3, a positioning chip 4, and a waterproof connector 5. The housing assembly 1 includes a housing 11 and an upper end cover 12 and a bottom cover 13 connected to the upper and lower ends of the housing 11. The waterproof connector 5 is connected to the housing assembly 1, with one end extending into the housing assembly 1 and communicating with the positioning chip 4, and the other end extending out of the housing assembly 1 and communicating with the underwater operation device. The first seal 2 and the second seal 3 are connected inside the housing assembly 1 and located at the upper and lower ends of the positioning chip 4. This application ensures the waterproof effect of the positioning device in deep water through the cooperation of the first seal 2 and the second seal 3.
[0035] Furthermore, to ensure the strength of the GPS signal transmission of the positioning device, the upper cover 12 is made of non-metallic material.
[0036] In some preferred embodiments of this application, such as Figures 1-3 As shown, the upper cover 12 is made of glass material, which not only does not affect GPS signal transmission, but also has advantages such as easy processing and molding, light weight, high strength and impact resistance.
[0037] Furthermore, such as Figure 4 As shown, furthermore, to ensure that the upper cover 12 can maintain a stable installation state within the housing assembly 1 and improve the structural strength and sealing performance of the entire waterproof GPS positioning device, this application provides a first limiting structure 111 inside the housing 11. In addition, the housing assembly 1 also specifically includes a pressure cap 14, which has a through hole that perfectly matches the shape of the upper cover 12. During installation, the bottom end of the upper cover 12 will tightly abut against the top end of the first limiting structure 111, while its periphery will simultaneously cooperate and tightly abut against the edge of the through hole of the pressure cap 14 and the inner wall of the housing 11 above the first limiting structure 111. This design not only effectively prevents the upper cover 12 from shaking or falling off during installation but also further enhances the stability and durability of the entire device.
[0038] In some preferred embodiments of this application, to facilitate the installation of the first sealing element 2, a first limiting groove is provided on the side of the first limiting structure 111 facing the upper end cover 12. The first sealing element 2 is installed and accommodated in the first limiting groove and is interference-fitted with the first limiting groove. Compared with opening a sealing groove on the periphery of the housing 11, the matching arrangement of the first limiting structure 111 and the first sealing element 2 ensures that the first sealing element 2 fits tightly against the first limiting structure 111 after installation, effectively preventing the first sealing element 2 from loosening or misaligning during installation, resulting in a more stable and reliable sealing effect. On the other hand, it makes full use of the limited space of the first limiting structure 111, making the structure of the entire device more compact.
[0039] In some preferred embodiments of this application, such as Figures 1-3 As shown, if the top height of the pressure cap 14 is higher than the top height of the upper cap 12, the surface of the device will be uneven, which will lead to increased water flow resistance, sediment deposition and accumulation, impaired sealing performance, difficult maintenance, and affect the overall aesthetics. The outer shell assembly 1 in this application also includes a filler cap 15, which is installed in the through hole of the pressure cap 14 and located on the side of the upper cap 12 away from the bottom cap 13. Its periphery matches and tightly abuts against the edge of the through hole of the pressure cap 14, and its top is flush with the top of the pressure cap 14.
[0040] In some preferred embodiments of this application, the filler cap 15 is made of a non-metallic material to reduce the impact on GPS signal transmission.
[0041] Furthermore, in order to achieve a stable connection between the cover 14 and the housing 11, the cover 14 is detachably connected to the housing 11 by one or more third fasteners.
[0042] In some preferred embodiments of this application, such as Figure 2 As shown, the waterproof connector 5 is installed on the bottom cover 13. One end of it extends into the housing 11 and is connected to the positioning chip 4, while the other end extends out of the housing 11 and is connected to the underwater operation device.
[0043] Furthermore, the bottom cover 13 has a through hole for installing the waterproof connector 5, and the waterproof connector 5 is threadedly connected to the through hole to ensure the connection stability between the waterproof connector 5 and the bottom cover 13.
[0044] In some preferred embodiments of this application, such as Figure 2 As shown, a second limiting structure 51 is provided on the outer periphery of the waterproof connector 5. The top of the second limiting structure 51 abuts tightly against the bottom of the bottom cover 13, forming a stable support point. This design not only further enhances the connection stability between the waterproof connector 5 and the bottom cover 13, but also effectively prevents loosening or detachment that may occur during use, thereby ensuring the sealing and reliability of the entire waterproof GPS positioning device in an underwater environment, and further improving the structural strength and durability of the device.
[0045] Furthermore, to prevent watertightness issues caused by gaps between the second limiting structure 51 and the bottom cover 13, a second limiting groove is provided on the side of the second limiting structure 51 facing the bottom cover 13. The second limiting groove contains a third sealing element 6 and is press-fitted with it. Furthermore, to completely eliminate any minor gaps that may exist between the second limiting structure 51 and the bottom cover 13 due to loose fit, thereby avoiding watertightness problems, a second limiting groove is provided on the side of the second limiting structure 51 facing the bottom cover 13. The second limiting groove is specifically designed to accommodate the third sealing element 6 and forms an press-fit with it, ensuring that the sealing element fits tightly between the limiting structure and the bottom cover after installation, effectively preventing moisture penetration.
[0046] In some preferred embodiments of this application, the first limiting structure 111, the upper end cover 12, the filling cover 15, the first sealing element 2, and the positioning chip 4 are arranged coaxially. This coaxial arrangement not only maintains the symmetry and balance of the structure but also helps to improve the accuracy and efficiency of assembly. Meanwhile, the waterproof connector 5 adopts an eccentric arrangement, breaking the traditional symmetrical layout and allowing for a more compact and efficient use of the internal space of the housing 11. This layout scheme, combining coaxial arrangement and eccentric design, not only makes the entire positioning device structure more compact and rational but also effectively improves its stability and durability in underwater environments.
[0047] In some specific embodiments of this application, the second seal 3 is located between the bottom cover 13 and the housing 11. The bottom cover 13 is detachably connected to the outer periphery of the housing 11 by one or more first fasteners. These first fasteners pass through the second seal 3 during the connection process, ensuring that the bottom cover 13 and the second seal 3 can be firmly connected to the housing 11 together. This design not only ensures the stability of the connection, but also effectively reduces the overall weight of the entire positioning device.
[0048] In some specific embodiments of this application, the bottom cover 13 is detachably connected to the positioning chip 4 via one or more second fasteners.
[0049] Furthermore, to prevent short circuits that may occur in the positioning chip 4 due to contact with conductive materials or current, the second fixing member in this application is made of insulating material. This design ensures that the positioning chip 4 maintains its electrical isolation during installation and use, even in humid or complex electromagnetic environments, effectively preventing current leakage or accidental short circuits, thereby improving the stability and reliability of the entire positioning device. The choice of insulating material not only protects the positioning chip 4 from physical damage but also ensures its continuous and accurate positioning function.
[0050] In some specific embodiments of this application, at least one mounting hole is provided on the periphery of the housing 11, through which the positioning device can be conveniently and easily installed onto the underwater operation device.
[0051] The various structures in this application are detachably connected, which is easier to disassemble and maintain and less expensive than the watertight method of epoxy resin potting.
[0052] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
