Description

Technical Field

[0001] This utility model relates to the field of charging structure technology, and in particular to a waterproof charging structure. Background Technology

[0002] Existing charging structures for underwater robots are shown in the attached diagram. Figure 14 As shown, the existing charging socket 5 consists of two retaining rings connected to the casing. The charging contacts extend out of the casing and are located inside the retaining rings. When the existing charging plug 4 is inserted into the existing charging socket 5, the water inside the retaining rings is squeezed out by the existing charging plug 4. However, this setting method easily leads to a small amount of water remaining at the connection between the existing charging socket 5, the existing charging plug 4, and the casing. The positive and negative terminals are in a conductive state during charging, which will cause electrolytic corrosion. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in related technologies. To this end, this invention provides a waterproof charging structure that solves the technical problem in the prior art where water easily accumulates between the positive and negative electrodes, leading to electrolytic corrosion. By setting a waterproof platform, water is prevented from remaining at the charging contacts, or even if water does remain, it is difficult to conduct water between the two charging contacts, thus improving the service life of the charging contacts and enhancing charging safety.

[0004] This utility model provides a waterproof charging structure, including:

[0005] A charging socket with charging contacts extending outward from the casing. The charging contacts are located in the charging socket, and a waterproof platform is provided on the top of the casing corresponding to the charging contacts.

[0006] A charging plug is inserted into the charging socket. The charging plug has a power connection hole corresponding to the position of the charging contact and a groove corresponding to the position of the waterproof platform.

[0007] A further improvement of the waterproof charging structure of this utility model is that the charging socket includes two blocking parts fixed to the housing, with a gap between the two blocking parts, and the charging contact extends outward from the housing and is located between the two blocking parts. The blocking part is U-shaped and includes two symmetrically arranged blocking edges and a baffle plate vertically connected to the two blocking edges.

[0008] A further improvement of the waterproof charging structure of this utility model is that a baffle of one of the blocking parts is provided with a limiting protrusion extending along the height direction on the side of the charging contact, and a limiting groove is provided on the charging plug corresponding to the position of the limiting protrusion. When the charging plug is inserted into the charging socket, the limiting protrusion is engaged in the limiting groove.

[0009] A further improvement of the waterproof charging structure of this utility model is that the charging socket includes a baffle plate connected to the housing, and the baffle plate has an insertion hole corresponding to the position of the charging plug.

[0010] A further improvement of the waterproof charging structure of this utility model is that the outer surface of the waterproof platform is arc-shaped, the cross-section of the groove is circular, the middle position of the waterproof platform is recessed towards the charging contact to form a sealing connection groove, and an insulating sealing ring is provided in the sealing connection groove.

[0011] A further improvement of the waterproof charging structure of this utility model is that the vertical cross-section of the sealing connection groove is any one of the following: arc shape, V shape, quadrilateral shape, pentagon shape, and hexagon shape, and the vertical cross-section shape of the insulating sealing ring matches the vertical cross-section shape of the sealing connection groove.

[0012] A further improvement of the waterproof charging structure of this utility model is that the inner wall of the groove is recessed inward to form an annular inner groove, and the annular inner groove is provided with a waterproof sealing ring.

[0013] A further improvement of the waterproof charging structure of this utility model is that the charging contacts have two or three;

[0014] When there are two charging contacts, both charging contacts are provided with the waterproof platform;

[0015] When there are three charging contacts, the two charging contacts on both sides are provided with the waterproof platform.

[0016] A further improvement of the waterproof charging structure of this utility model is that the bottom outer surface of the waterproof platform protrudes away from the charging contacts to form a water guiding surface, and the shape of the groove matches the shape of the waterproof platform.

[0017] A further improvement of the waterproof charging structure of this utility model is that the charging plug includes a head and a tail, the tail is inserted into two charging plugs, the power connection hole is opened in the tail, and the external wire passes through the head and is correspondingly arranged in the power connection hole. The external wire is used to connect the charging contacts.

[0018] This invention facilitates water drainage from the charging contacts by providing two baffles, and prevents water from remaining at the charging contacts or, even if it does, making it difficult for the two charging contacts to conduct electricity. This improves the service life of the charging contacts and enhances charging safety. The addition of limiting protrusions and grooves improves the connection stability of the charging plug and socket. The water-guiding surface formed at the bottom of the waterproof platform enhances water drainage and prevents water from the top of the casing from entering the electrical connection hole. The sealing ring on the waterproof platform further improves the insulation between the two charging contacts and prevents electrochemical corrosion.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The following embodiments are used to illustrate this utility model but should not be used to limit its scope.

[0038] The following is combined Figures 1 to 3This utility model describes a waterproof charging structure, including a charging socket 2 and a charging plug 1. A charging contact 301 extends outward from the housing 3, and a waterproof platform 202 is provided on the top of the charging contact 301 corresponding to the top of the housing 3. The charging plug 1 is inserted into the charging socket 2, and a power connection hole 105 is provided on the charging plug 1 corresponding to the position of the charging contact 301. A groove 104 is provided on the charging plug 1 corresponding to the position of the waterproof platform 202.

[0039] Example 1

[0040] like Figure 7 , Figure 8 and Figure 9 As shown, the charging socket 2 includes two symmetrically arranged baffles 201 fixed to the housing 3, with a gap between them. The charging contact 301 extends outward from the housing 3 and is located between the two baffles 201. The baffles 201 are U-shaped and include two symmetrically arranged baffles and a baffle plate vertically connected to the two baffles. The two baffles have a certain width, which can better prevent water from entering from both sides. The gap between the baffles of the two baffles 201 facilitates the smooth drainage of water. This design not only enhances the structural strength of the baffles 201 but also improves its waterproof performance. When the charging plug 1 is inserted into the charging socket 2, the two baffles can effectively prevent water from entering from both sides of the plug, thereby ensuring the safety and reliability of the charging process.

[0041] It should be noted that the blocking part 201 can also be arc-shaped or V-shaped.

[0042] Furthermore, such as Figure 7 , Figure 8 and Figure 9 As shown, there are two charging contacts 301. The extension direction of the baffle corresponds to the extension direction of the line connecting the two charging contacts 301. This arrangement ensures the stability of the charging contacts 301. Since the extension direction of the baffle is consistent with the direction of the line connecting the two charging contacts 301, it can effectively prevent the charging contacts 301 from shifting or loosening when subjected to external force, thereby ensuring the stability and reliability of the charging process. This arrangement also improves waterproof performance. The baffle can effectively block water from entering from both sides of the charging plug 1, avoiding water corrosion of the charging contacts 301 and the internal circuit of the housing 3, thereby extending the service life of the waterproof charging structure and improving safety. This arrangement also has the advantages of simple structure, easy manufacturing and installation. The structure of the charging contacts 301 and the baffle is relatively simple, without the need for complex processing technology and expensive material costs. At the same time, the installation process is also very simple, reducing manufacturing costs and time costs.

[0043] Furthermore, such as Figure 7 , Figure 8 and Figure 9As shown, a baffle of a stop part 201 is provided with a limiting protrusion 204 extending along the height direction on the side of the charging contact 301. The charging plug 1 is provided with a limiting groove 106 at the position of the limiting protrusion 204. When the charging plug 1 is inserted into the charging socket 2, the limiting protrusion 204 is engaged in the limiting groove 106, which enhances the connection stability between the charging plug 1 and the charging socket 2. The cooperation between the limiting protrusion 204 and the limiting groove 106 not only restricts the movement of the charging plug 1 in the horizontal direction, but also prevents the charging plug 1 from falling off in the vertical direction to a certain extent. Even in bumpy or vibrating environments, the charging connection can be ensured to be stable. In addition, the design of the limiting protrusion 204 and the limiting groove 106 also makes it easier for users to correctly align and insert the charging plug 1, improving the convenience of use.

[0044] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the cross-section of the limiting protrusion 204 is semi-circular, and the cross-section of the limiting groove 106 is semi-circular, matching the cross-section of the limiting protrusion 204.

[0045] It should be noted that both baffles may also be provided with limiting protrusions 204, and the two limiting protrusions 204 are arranged symmetrically.

[0046] like Figure 7 , Figure 8 and Figure 9 As shown, the corner where the baffle and the edge connect is rounded, which not only improves the aesthetics of the overall structure, but also reduces the risk of wear or scratches caused by sharp edges during use. The rounded corner also helps to disperse the impact of external forces on the structure, enhancing the durability and reliability of the entire waterproof charging structure.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, the outer surface of the waterproof platform 202 is arc-shaped, and the cross-section of the groove 104 is circular. The middle position of the waterproof platform 202 is recessed towards the charging contact 301 to form a sealing connection groove. An insulating sealing ring 203 is provided in the sealing connection groove. The setting of the insulating sealing ring 203 effectively prevents moisture or humidity from penetrating into the charging contact 301 through the tiny gap between the waterproof platform 202 and the charging contact 301, ensuring the safety and stability of the charging process. The recessed design of the sealing connection groove allows the insulating sealing ring 203 to fit tightly around the charging contact 301.

[0048] Specifically, the vertical cross-section of the sealing connection groove is any one of the following: arc shape, V-shape, quadrilateral, pentagon, and hexagon. The shape of the vertical cross-section of the insulating sealing ring matches the shape of the vertical cross-section of the sealing connection groove. When the vertical cross-section of the sealing connection groove is arc shape, the insulating sealing ring is an O-ring; when the vertical cross-section of the sealing connection groove is V-shaped, the insulating sealing ring is a V-ring; and when the vertical cross-section of the sealing connection groove is quadrilateral, pentagon, or hexagon, the insulating sealing ring is a star-shaped sealing ring.

[0049] Preferably, the height of the blocking part 201 is higher than the height of the charging contact 301.

[0050] Preferably, the bottom outer surface of the waterproof platform 202 protrudes away from the charging contact 301 to form a water-guiding surface. The shape of the groove 104 matches the shape of the waterproof platform 202, which can more effectively prevent moisture or dampness from penetrating into the charging contact 301 through the tiny gap between the waterproof platform 202 and the charging contact 301, thus ensuring the safety and stability of the charging process.

[0051] like Figure 4 , Figure 5 and Figure 6 As shown, the charging plug 1 includes a head 102 and a tail 103. The tail 103 is inserted between two blocking parts 201. The power connection hole 105 is opened in the tail 103. The external wire 101 passes through the head 102 and is correspondingly disposed in the power connection hole 105. The external wire 101 is used to connect to the charging contact 301.

[0052] This utility model facilitates water drainage from the charging contacts 301 by providing two baffles 201, and prevents water from remaining at the charging contacts 301 or making it difficult for the two charging contacts 301 to conduct electricity even if water remains, thus improving the service life of the charging contacts 301 and enhancing charging safety. The limiting protrusion 204 and limiting groove 106 improve the connection stability between the charging plug 1 and the charging socket 2. The water-guiding surface formed at the bottom of the waterproof platform 202 improves the water drainage effect and prevents water from the top of the housing 3 from entering the electrical connection hole 105. The sealing ring provided in the waterproof platform 202 further improves the insulation effect between the two charging contacts 301 and prevents electrochemical corrosion.

[0053] Example 2

[0054] like Figure 10 and Figure 11As shown, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 has three charging contacts. The two charging contacts on the sides have waterproof platforms, while the middle charging contact does not. The charging plug has a central connection hole 1041 corresponding to the middle charging contact. This middle charging contact can serve as a backup charging contact 3011. When either of the two side charging contacts malfunctions or is damaged, it can connect to the middle charging contact through the central connection hole, ensuring continuous charging and improving the fault tolerance and practicality of the charging structure. Simultaneously, the waterproof platforms are retained on the side charging contacts, effectively preventing moisture from entering from the sides of the charging plug and ensuring the safety and reliability of the middle charging contact in emergency use. This design not only enhances waterproof performance but also improves the flexibility and durability of the charging structure, providing users with a more convenient and safer charging experience.

[0055] In other specific implementation cases, the barrier 201 can also be arc-shaped or V-shaped.

[0056] Example 3

[0057] like Figure 12 As shown, the charging socket includes a retaining plate 107 connected to the housing, and the retaining plate has an insertion hole corresponding to the position of the charging plug.

[0058] The outer surface of the waterproof platform 202 is arc-shaped, and the cross-section of the groove 104 is circular. The middle position of the waterproof platform 202 is recessed towards the charging contact 301 to form a sealing connection groove. An insulating sealing ring 203 is provided in the sealing connection groove. The setting of the insulating sealing ring 203 effectively prevents moisture or humidity from penetrating into the charging contact 301 through the tiny gap between the waterproof platform 202 and the charging contact 301, ensuring the safety and stability of the charging process. The recessed design of the sealing connection groove allows the insulating sealing ring 203 to fit tightly around the charging contact 301.

[0059] Specifically, the vertical cross-section of the sealing connection groove can be any one of the following: circular arc, V-shape, quadrilateral, pentagon, or hexagon. When the vertical cross-section of the sealing connection groove is circular arc, the insulating sealing ring is an O-ring; when the vertical cross-section of the sealing connection groove is V-shaped, the insulating sealing ring is a V-ring; and when the vertical cross-section of the sealing connection groove is quadrilateral, pentagon, or hexagon, the insulating sealing ring is a star-shaped sealing ring.

[0060] Preferably, the bottom outer surface of the waterproof platform 202 protrudes away from the charging contact 301 to form a water-guiding surface. The shape of the groove 104 matches the shape of the waterproof platform 202, which can more effectively prevent moisture or dampness from penetrating into the charging contact 301 through the tiny gap between the waterproof platform 202 and the charging contact 301, thus ensuring the safety and stability of the charging process.

[0061] The charging plug 1 includes a head 102 and a tail 103. The tail 103 is inserted into the insertion hole of the baffle plate, and the power connection hole 105 is opened in the tail 103. The external wire 101 passes through the head 102 and is correspondingly disposed in the power connection hole 105. The external wire 101 is used to connect to the charging contact 301.

[0062] Example 4

[0063] like Figure 13 As shown, the charging socket includes a retaining plate 107 connected to the housing, and the retaining plate has an insertion hole corresponding to the position of the charging plug.

[0064] The outer surface of the waterproof platform 202 is arc-shaped, the cross-section of the groove 104 is circular, and the inner wall of the groove is recessed inward to form an annular inner groove 205, which is equipped with a waterproof sealing ring.

[0065] Preferably, the bottom outer surface of the waterproof platform 202 protrudes away from the charging contact 301 to form a water-guiding surface. The shape of the groove 104 matches the shape of the waterproof platform 202, which can more effectively prevent moisture or dampness from penetrating into the charging contact 301 through the tiny gap between the waterproof platform 202 and the charging contact 301, thus ensuring the safety and stability of the charging process.

[0066] The charging plug 1 includes a head 102 and a tail 103. The tail 103 is inserted into the insertion hole of the baffle plate, and the power connection hole 105 is opened in the tail 103. The external wire 101 passes through the head 102 and is correspondingly disposed in the power connection hole 105. The external wire 101 is used to connect to the charging contact 301.
