Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rescue radio technology, and in particular relates to a portable charging adapter for rescue radios. Background Technology
[0002] Lifesaving radios are primarily used in ship communication and navigation within marine engineering. They are watertight, lightweight, and self-buoyant, and can automatically transmit international distress signals (SOS). They can also be used for manual telegraph communication. The adapter is a crucial component of the lifesaving radio, providing a stable and reliable power supply. When an external power source is connected, the adapter's internal switching transistors and control circuits activate. By controlling the switching transistors' on / off times, the adapter efficiently converts and stabilizes the input power. The converted DC power is then rectified and sent to the lifesaving radio's battery to charge it. In maritime applications, charging a lifesaving radio typically involves placing the adapter on a flat surface and connecting it to the fixed radio, then connecting the adapter's charging plug to the power source. However, when a ship is at sea, the waves and wind cause the hull and objects inside the cabin to sway. Due to the adapter's relatively large mass, it often wobbles, and the connection to the power source can easily detach, interrupting charging. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a portable charging adapter for a life-saving radio, which clamps the adapter body and improves the stability of the adapter body during operation.
[0004] Specifically, this utility model discloses a portable charging adapter for a life-saving radio, comprising:
[0005] The adapter body includes an adapter housing, a printed circuit board inside the adapter housing, and a power module;
[0006] A mounting bracket fixed to the hull, the mounting bracket having a clamping assembly for clamping the adapter body, and the mounting bracket also having an elastic element connected to the adapter body, wherein;
[0007] The back of the adapter housing is provided with a connection portion that is adapted to the elastic element.
[0008] By adopting the above solution, the charging adapter body is inserted into the mounting bracket to fix the adapter body, and the elastic element on the mounting bracket is connected to the connecting part of the adapter body. Even if the shaking is large and the charging adapter is detached from the mounting bracket, the connecting part can prevent the charging adapter from falling, which would cause charging to stop or damage the adapter.
[0009] Furthermore, the adapter housing includes a cover plate and a base plate that matches the cover plate, and the inner surface of the cover plate has a thermally conductive protrusion. A thermally conductive silicone pad is provided between the thermally conductive protrusion and the printed circuit board, and the power module is connected to the base plate by screws.
[0010] By adopting the above solution, the thermally conductive protrusions allow the thermally conductive silicone pads to be placed close to the cover plate, thus better transferring the heat from the electronic components on the printed circuit board to the cover plate. Similarly, the screws ensure that the power module is in close contact with the base plate, transferring the heat generated by the power module to the base plate, thereby improving the heat dissipation efficiency of the electronic components and the power module, and extending their service life.
[0011] Furthermore, the cover plate has an annular boss inside, and the base plate has a groove that matches the annular boss.
[0012] By adopting the above solution, the boss and the slot make the cover plate and the base plate fit together tightly, which can better prevent electromagnetic signals from radiating into or out from the gap between the cover plate and the base, thus improving the electromagnetic compatibility of the adapter.
[0013] Furthermore, the upper surface of the cover plate, the lower surface of the bottom plate, and the side wall of the bottom plate are all provided with heat dissipation grooves.
[0014] By adopting the above solution, the heat sink design further improves the heat dissipation efficiency of heat-generating components and power modules on the printed circuit board inside the adapter.
[0015] Furthermore, the bottom of the mounting bracket is provided with a connection and fixing structure to the hull, the fixing structure including but not limited to screw structure and adhesive structure.
[0016] By adopting the above scheme, the fixed structure facilitates the installation of the bracket. When the hull surface is smooth, an adhesive structure can be used, and when the hull surface is rough, a screw structure can be used for fixing.
[0017] Furthermore, the clamping assembly includes a clamping base plate, a clamping lower plate slidably connected to the clamping base plate, and clamping side plates disposed on both sides of the clamping base plate. The clamping base plate is fixedly connected to the mounting bracket. One clamping side plate is fixedly connected to the clamping base plate, and the other clamping side plate is slidably connected to the clamping base plate via a side guide rod and a return spring.
[0018] The clamping lower plate is threadedly connected to the clamping base plate via a lower guide rod, and the reset spring is placed between the clamping base plate and the side guide rod.
[0019] By adopting the above scheme, the sliding clamping side plate facilitates the installation of the adapter body, the clamping lower plate can adjust the installation position of the adapter body in the clamping assembly, and the clamping lower plate and the two clamping side plates restrict the displacement of the adapter body in three directions, thereby improving the stability of the adapter body in the clamping assembly.
[0020] Furthermore, the elastic element is an elastic rope, and the end of the elastic rope has a spherical structure.
[0021] By adopting the above solution, the elastic rope has a simple structure, low cost, and its spherical structure at the end facilitates connection with the adapter body.
[0022] Furthermore, the connecting part has a cavity for accommodating the spherical structure, and the side wall of the connecting part has a channel communicating with the cavity, the opening direction of the channel being perpendicular to the side wall of the adapter body.
[0023] By adopting the above solution, the spherical structure at the end of the elastic rope is inserted into the cavity along the channel, and the opening direction of the channel is perpendicular to the side wall of the adapter body. This reduces the risk of the adapter body falling when it is vibrated or shaken and comes off the clamping assembly.
[0024] Furthermore, the sidewall of the connecting part is provided with a dovetail groove and a baffle that slides along the dovetail groove, the contour of the baffle matching the contour of the connecting part.
[0025] By adopting the above scheme, the baffle can rotate around the connecting part along the dovetail groove. After the spherical structure is inserted into the cavity, the baffle is rotated to cover the channel, preventing the spherical structure from separating from the connecting part, thus improving the stability of the connector and the connecting part.
[0026] Furthermore, the adapter housing is made of metal.
[0027] By adopting the above solution, using metal materials can improve heat dissipation and give the adapter body better electromagnetic compatibility. Attached Figure Description

Detailed Implementation
[0037] The present invention will now be described in further detail with reference to the accompanying drawings.
[0038] like Figure 1-7 As shown, this utility model discloses a portable charging adapter for a life-saving radio, comprising:
[0039] The adapter body 1 includes an adapter housing 11, a printed circuit board 12 inside the adapter housing 11, and a power module 13.
[0040] A mounting bracket 2 fixed to the hull, the mounting bracket 2 is provided with a clamping component 3 for clamping the adapter body 1, and the mounting bracket 2 is also provided with an elastic element 4 connected to the adapter body 1, wherein;
[0041] The back of the adapter housing 11 is provided with a connecting part 14 that is adapted to the elastic member 4.
[0042] In this invention, the adapter body 1 is inserted into the mounting bracket 2 to fix the adapter body 1, and the elastic member 4 on the mounting bracket 2 is connected to the connecting part 14 of the adapter body 1. Even if the shaking amplitude is large and the charging adapter is detached from the mounting bracket 2, the connecting part can prevent the charging adapter from falling, resulting in charging termination or damage to the adapter.
[0043] The adapter housing 11 includes a cover plate 111 and a base plate 112 that matches the cover plate 111. The inner surface of the cover plate 111 has a thermally conductive protrusion 113. A thermally conductive silicone pad 114 is provided between the thermally conductive protrusion 113 and the printed circuit board 12. The power module 13 is connected to the base plate 112 by screws. The thermally conductive protrusion 113 allows the thermally conductive silicone pad 114 to be close to the cover plate 111, which better transfers the heat from the electronic components on the printed circuit board 12 to the cover plate 111. Similarly, the screws make the power module 13 fit tightly against the base plate 112, transferring the heat generated by the power module 13 to the base plate 112, which improves the heat dissipation efficiency of the electronic components and the power module 13 and extends its service life.
[0044] The adapter body 1 has an input cable and an output cable on one side, and a switch on the other side. The output cable connects to the plug-in part. Placing the input cable and output cable on the same side reduces the space occupied by the adapter body 1.
[0045] In addition, the cover plate 111 has an annular boss 115 inside, and the base plate 112 has a slot 116 that matches the annular boss 115. The boss and the slot 116 make the cover plate 111 and the base plate 112 fit tightly, which can better prevent electromagnetic signals from radiating into or out from the gap between the cover plate 111 and the base, thus improving the electromagnetic compatibility of the adapter.
[0046] To improve the heat dissipation of the adapter, heat dissipation grooves 117 are provided on the upper surface of the cover plate 111, the lower surface of the base plate 112, and the side wall of the base plate 112, which further improves the heat dissipation efficiency of the heat-generating components and power module 13 on the printed circuit board 12 inside the adapter.
[0047] On the other hand, the bottom of the mounting bracket 2 is provided with a fixing structure 21 for connection with the hull. The fixing structure 21 includes, but is not limited to, screw structure and adhesive structure. When the hull surface is smooth, the adhesive structure can be used; when the hull surface is rough, the screw structure can be used for fixing.
[0048] In some embodiments of this utility model, the clamping assembly 3 includes a clamping base plate 31, a clamping lower plate 32 slidably connected to the clamping base plate 31, and clamping side plates 33 disposed on both sides of the clamping base plate 31. The clamping base plate 31 is fixedly connected to the mounting bracket 2. One clamping side plate 33 is fixedly connected to the clamping base plate 31, and the other clamping side plate 33 is slidably connected to the clamping base plate 31 via a side guide rod 34 and a return spring 35. The clamping lower plate 32 is threadedly connected to the clamping base plate 31 via a lower guide rod 36, and the return spring 35 is placed between the clamping base plate 31 and the side guide rod 34. In this embodiment, the slidably disposed clamping side plate 33 facilitates the installation of the adapter body 1, the clamping lower plate 32 can adjust the installation position of the adapter body 1 in the clamping assembly 3, and the clamping lower plate 32 and the two clamping side plates 33 restrict the displacement of the adapter body 1 in three directions, thereby improving the stability of the adapter body 1 in the clamping assembly 3.
[0049] In some embodiments of this utility model, the elastic element 4 is an elastic rope, and the end of the elastic rope has a spherical structure 41. The elastic rope has a simple structure and low cost, and the spherical structure 41 at its end is convenient to connect with the adapter body 1.
[0050] In some embodiments of this invention, the connecting portion 14 has a cavity 141 for accommodating the spherical structure 41, and the side wall of the connecting portion 14 has a channel 142 communicating with the cavity 141, the opening direction of the channel 142 being perpendicular to the side wall of the adapter body 1. By inserting the spherical structure 41 at the end of the elastic cord into the cavity 141 along the channel 142, the risk of the charging adapter body 1 falling off when it is vibrated or shaken and dislodged from the clamping assembly 3 can be reduced.
[0051] In addition, the side wall of the connecting part 14 is provided with a dovetail groove 143 and a baffle 144 that slides along the dovetail groove 143. The outline of the baffle 144 matches the outline of the connecting part 14. The baffle 144 rotates around the connecting part 14 along the dovetail groove 143. After the spherical structure 41 is inserted into the cavity 141, the baffle 144 is rotated to cover the channel 142, preventing the spherical structure 41 from separating from the connecting part 14 and improving the stability of the connector and the connecting part 14.
[0052] In some embodiments of this invention, the adapter housing 11 is made of metal. The metal material improves heat dissipation and gives the adapter body 1 better electromagnetic compatibility.
[0053] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
