Description

Technical Field

[0001] This invention relates to the field of protective structure technology, specifically to an environmentally adaptive outdoor power interface protective structure. Background Technology

[0002] Outdoor power supplies, as portable power supply devices, are widely used in camping, outdoor work, emergency rescue, and other scenarios. The interface, as the core connection, directly determines the safety and reliability of the device. Current outdoor power supply interface protection structures mostly rely on sealing caps for sealing protection.

[0003] Existing outdoor power interface protection structures have many intractable defects: First, the protection activation lacks environmental adaptability and relies entirely on manual operation. In the event of sudden severe weather such as rain, if the protective cover is not closed or the protective components are not adjusted in time, rainwater can easily directly splash onto the interface surface or seep into the interior through the gaps between the protective shell and the protective cover. Second, the protection level is singular. Most structures rely only on the physical shielding of the protective cover or the sealing of a simple sealing ring, failing to form a collaborative protection mechanism of "shielding + sealing". Especially after the plug is inserted into the interface, gaps are easily left at the connection between the plug and the interface, allowing moisture to still penetrate through the gaps. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an environmentally adaptive outdoor power interface protection structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmentally adaptive outdoor power interface protection structure, comprising an outdoor power supply body and a protective shell installed on one side of the outdoor power supply body. The protective shell is installed at the interface of the outdoor power supply body. The interior of the protective shell is provided with a through groove corresponding to the interface of the outdoor power supply body. A protective cover is rotatably connected to one side of the outer surface of the protective shell via a hinge. A shielding mechanism is installed inside the protective shell. A sealing mechanism is installed inside the protective shell. A driving mechanism that cooperates with the shielding mechanism and the sealing mechanism is installed inside the protective shell. A triggering mechanism that cooperates with the driving mechanism is installed on the protective shell. The shielding mechanism includes a U-shaped groove formed on the front side of the protective shell, and a U-shaped shield is slidably connected inside the U-shaped groove; The sealing mechanism includes an annular frame fixedly connected inside the through groove, and an annular sealing airbag fixedly connected inside the annular frame. The drive mechanism includes a mounting groove inside the protective shell. A first spring is provided inside the mounting groove. One end of the first spring is provided with a push plate that is slidably connected to the inner wall of the mounting groove. A first push rod is fixedly connected to one side of the push plate. One end of the first push rod extends into the interior of the U-shaped groove and contacts one side of the U-shaped shield.

[0006] Preferably, the protective shell has an internal compression chamber, one end of which is connected to the interior of the annular sealing airbag via a pipe. A piston plate is slidably connected to the interior of the compression chamber, and a second push rod is fixedly connected between one side of the push plate and the piston plate.

[0007] When the first spring moves the push plate, it can drive the second push rod to move the piston plate, thereby inflating the annular sealing airbag. After the annular sealing airbag inflates, it can squeeze and seal the cable and other parts of the plug, reducing the entry of moisture.

[0008] Preferably, the triggering mechanism includes a groove on the top of the protective shell, an absorbent sponge placed inside the groove, a movable plate on one side of the absorbent sponge, the movable plate being slidably connected to the inner wall of the groove, a stepped hole communicating with the top of the mounting slot at the bottom of the groove and below the movable plate, a stop bar for locking the push plate being slidably connected inside the stepped hole, and a second spring being fixedly connected between the outside of the stop bar and the stepped hole.

[0009] The absorbent sponge expands after absorbing water and pushes the moving plate, causing the stop bar to lose its obstruction. The stop bar moves upward under the action of the second spring, causing the push plate to lose its obstruction. At this time, the first spring can drive the push plate to move normally.

[0010] Preferably, the absorbent sponge is made of water-absorbing resin, and the top and bottom ends of the baffle are both provided with arc-shaped surfaces, and the arc-shaped surfaces are located on the side away from the absorbent sponge. The absorbent sponge made of water-absorbing resin can not only absorb water and expand, but can also be reused after the water is squeezed out, reducing losses. The arc-shaped surfaces facilitate the repositioning of the push plate and the moving plate.

[0011] Preferably, the bottom end of the absorbent sponge has an opening that matches the top end of the baffle, and a U-shaped baffle that contacts the inner wall of the opening is fixedly connected to one side of the bottom end of the movable plate. This allows the baffle to move upward normally without affecting the outward expansion of the absorbent sponge, thus enabling the movable plate to move stably.

[0012] Preferably, a third push rod is fixedly connected to one side of the movable plate, and a limiting groove is opened inside the protective shell, which communicates with the top of the U-shaped groove of the connecting plate. A limiting plate is fixedly connected to the top of the U-shaped shield inside the limiting groove, and the other end of the third push rod extends into the limiting groove and contacts one side of the limiting plate.

[0013] When the U-shaped shield is reset, the third push rod will be pushed by the limiting plate, which in turn will cause the moving plate to squeeze the water-absorbing sponge.

[0014] Preferably, a top cover is embedded in the top of the groove, and the top cover has multiple water inlet holes. Drainage holes are provided on both sides of the bottom of the groove. The water inlet holes facilitate the absorption of water by the absorbent sponge, and the drainage holes facilitate the drainage of water by the absorbent sponge.

[0015] Preferably, a U-shaped sealing ring is fixedly connected to one side of the protective cover, and a U-shaped sealing groove that matches the U-shaped sealing ring is opened on the front side of the protective shell. The protective cover and the protective shell are magnetically attracted to each other, which can increase the sealing performance between the protective cover and the protective shell.

[0016] Preferably, the top and bottom of the protective shell are fixedly connected with mounting strips, and the mounting strips have multiple mounting holes. The mounting strips are connected to the outdoor power supply body through the mounting holes and screws. A sealing gasket is provided between the protective shell and the outdoor power supply body to facilitate the installation of the protective structure and increase the sealing between the protective structure and the outdoor power supply body.

[0017] This invention provides an environmentally adaptive outdoor power interface protection structure. It has the following beneficial effects: This environmentally adaptive outdoor power interface protection structure automatically senses outdoor rain conditions through a trigger mechanism with a water-absorbing sponge (made of water-absorbing resin). It triggers protective actions without manual intervention, achieving environmentally adaptive protection to adapt to complex and changing outdoor weather conditions. The drive mechanism simultaneously drives the shielding and sealing mechanisms. The U-shaped shield moves forward to physically shield the interface, while the annular sealing airbag expands to achieve a tight seal at the plug-interface connection, forming "double protection" and significantly improving waterproof and dustproof performance. The U-shaped sealing ring of the protective cover and the U-shaped sealing groove of the protective shell, along with the sealing gasket between the protective shell and the outdoor power supply body, further enhance the overall sealing performance, preventing water leakage from multiple gaps. The water-absorbing sponge can be reused by squeezing out water, reducing losses and operating costs. The protective shell can be easily installed using the mounting holes on the mounting strip and screws, resulting in high efficiency for disassembly and maintenance. The overall structure is highly coordinated, with each component operating smoothly, effectively protecting the outdoor power interface from harsh environments, preventing moisture-induced short circuits, and ensuring the safety and lifespan of the outdoor power supply.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0021] like Figures 1 to 7 As shown, an environmentally adaptive outdoor power interface protection structure includes an outdoor power supply body 1 and a protective shell 2 installed on one side of the outdoor power supply body 1. The protective shell 2 is installed at the interface of the outdoor power supply body 1. The interior of the protective shell 2 is provided with a through groove corresponding to the interface of the outdoor power supply body 1. A protective cover 3 is rotatably connected to one side of the outer surface of the protective shell 2 via a hinge. A shielding mechanism 4 and a sealing mechanism 5 are installed inside the protective shell 2. A driving mechanism 6 that cooperates with the shielding mechanism 4 and the sealing mechanism 5 is installed inside the protective shell 2. A triggering mechanism 7 that cooperates with the driving mechanism 6 is installed on the protective shell 2.

[0022] Specifically: like Figure 4 , Figure 5 and Figure 7 As shown, the shielding mechanism 4 includes a U-shaped groove 41 opened on the front side of the protective shell 2, and a U-shaped shield 42 is slidably connected inside the U-shaped groove 41.

[0023] In rainy weather, the U-shaped cover 42 moves forward to shield the front of the outdoor power interface, preventing rainwater from directly entering the interior and providing protection.

[0024] like Figure 4 and Figure 5 As shown, the sealing mechanism 5 includes an annular frame 51 fixedly connected inside the through groove, and an annular sealing airbag 52 is fixedly connected inside the annular frame 51.

[0025] When the plug is inserted into the interface of the outdoor power supply body 1, the handle of the plug or the cable will be located inside the annular sealing airbag 52. When the annular sealing airbag 52 is inflated, it will press against the handle of the plug or the cable, thereby sealing the inside of the protective shell 2, which can further prevent moisture from entering and avoid affecting the outdoor power supply.

[0026] like Figures 4 to 7 As shown, the drive mechanism 6 includes a mounting groove 61 inside the protective shell 2. A first spring 62 is provided inside the mounting groove 61. One end of the first spring 62 is provided with a push plate 63 that is slidably connected to the inner wall of the mounting groove 61. A first push rod 64 is fixedly connected to one side of the push plate 63. One end of the first push rod 64 extends into the interior of the U-shaped groove 41 and contacts one side of the U-shaped shield 42.

[0027] When the push plate 63 is no longer obstructed, the first spring 62 will drive the push plate 63 to move outward. The movement of the push plate 63 will push the U-shaped shield 42 forward through the first push rod 64, forming a shield in front of the outdoor power interface.

[0028] Furthermore, the protective shell 2 has an internal compression chamber 65. One end of the compression chamber 65 is connected to the interior of the annular sealing airbag 52 through a pipe. The internal compression chamber 65 is slidably connected to a piston plate 66. A second push rod 67 is fixedly connected between one side of the push plate 63 and the piston plate 66.

[0029] When the push plate 63 moves, it will also push the piston plate 66 to move through the second push rod 67. The piston plate 66 moves in the extrusion chamber 65 and can inflate the annular sealing airbag 52 through the pipe.

[0030] like Figures 4 to 7 As shown, the triggering mechanism 7 includes a groove 71 on the top of the protective shell 2. An absorbent sponge 72 is placed inside the groove 71. A movable plate 73 is provided on one side of the absorbent sponge 72. The movable plate 73 is slidably connected to the inner wall of the groove 71. A stepped hole 74 is provided at the bottom of the groove 71 and below the movable plate 73, which communicates with the top of the mounting groove 61. A stop bar 75 for locking the push plate 63 is slidably connected inside the stepped hole 74. A second spring 76 is fixedly connected between the outside of the stop bar 75 and the stepped hole 74.

[0031] When it rains, the water-absorbing sponge 72 absorbs water and expands, which in turn pushes the moving plate 73 to move. When the moving plate 73 moves to one side of the stop bar 75, the stop bar 75 loses its obstruction and moves upward under the action of the second spring 76, so that the push plate 63 loses its obstruction. At this time, the first spring 62 can drive the push plate 63 to move normally.

[0032] Preferably, the absorbent sponge 72 is made of absorbent resin, and the top and bottom ends of the baffle 75 are provided with arc-shaped surfaces, and the arc-shaped surfaces are located on the side away from the absorbent sponge 72.

[0033] The water-absorbing sponge 72 made of water-absorbing resin can not only expand rapidly when absorbing water, but also can be reused after squeezing out water, reducing the frequency of replacement and lowering the cost of use; the arc-shaped surfaces set at both ends of the stop bar 75 facilitate the push plate 63 and the moving plate 73 to squeeze and move respectively.

[0034] Preferably, the bottom end of the absorbent sponge 72 is provided with an opening that matches the top end of the baffle 75, and a U-shaped baffle that contacts the inner wall of the opening is fixedly connected to one side of the bottom end of the movable plate 73.

[0035] The U-shaped baffle not only facilitates the movement of the movable plate 73 by allowing the absorbent sponge 72 to expand and move, but also ensures that the movable plate 736 can move normally during reset. like Figures 4 to 7 As shown, a third push rod 77 is fixedly connected to one side of the movable plate 73. The protective shell 2 has a limiting groove 43 that communicates with the top of the connecting plate U-shaped groove 41. The limiting groove 43 has a limiting plate 44 fixedly connected to the top of the U-shaped shield 42. The other end of the third push rod 77 extends into the limiting groove 43 and contacts one side of the limiting plate 44. A top cover 78 is embedded in the top of the groove 71. Multiple water inlet holes 79 are opened on the top cover 78. Drainage holes are opened on both sides of the bottom of the groove 71.

[0036] When the U-shaped shield 42 is pushed back to reset, it will drive the limiting plate 44 to push the third push rod 77 to move. The movement of the third push rod 77 can push the moving plate 73 to move and squeeze the water-absorbing sponge 72. The water in the water-absorbing sponge 72 can be discharged through the drainage holes on both sides for convenient subsequent use. The water inlet hole 79 can allow rainwater to enter the groove 71 smoothly and be absorbed by the water-absorbing sponge 72.

[0037] like Figure 2 and Figure 3 As shown, a U-shaped sealing ring 8 is fixedly connected to one side of the protective cover 3, and a U-shaped sealing groove 9 that matches the U-shaped sealing ring 8 is opened on the front side of the protective shell 2. The protective cover 3 and the protective shell 2 are magnetically attracted to each other.

[0038] When the protective cover 3 is closed, the U-shaped sealing ring 8 will enter the U-shaped sealing groove 9, thereby increasing the sealing between the protective cover 3 and the protective shell 2.

[0039] The top and bottom of the protective shell 2 are fixedly connected with mounting strips 10. Multiple mounting holes 11 are provided on the mounting strips 10. The mounting strips 10 are connected to the outdoor power supply body 1 through the mounting holes 11 and screws. A sealing gasket 12 is provided between the protective shell 2 and the outdoor power supply body 1.

[0040] The protective housing 2 can be easily installed on the outdoor power supply body 1 using screws and mounting holes 11, and the sealing gasket 12 can increase the sealing performance at the contact point between the protective housing 2 and the outdoor power supply body 1.

[0041] Working principle: In the initial state of the protective structure, the stop rod 75 of the trigger mechanism 7 clamps the push plate 63 of the drive mechanism 6 along the stepped hole 74, and the first spring 62 is in a compressed state. When it rains outdoors, rainwater enters the groove 71 through the water inlet hole 79 of the top cover 78 on the top groove 71 of the protective shell 2, and is absorbed by the water-absorbing sponge 72 in the groove 71. After the water-absorbing sponge 72 absorbs water and expands, it pushes the moving plate 73 to slide along the inner wall of the groove 71. After the moving plate 73 moves away, the stop rod 75 loses its obstruction and moves upward along the stepped hole 74 under the elastic force of the second spring 76, and the push plate 63 is released from its limit. At this time, the first spring 62 releases its elastic force and pushes the push plate 63 to slide along the mounting groove 61. On the one hand, the push plate 63 pushes the U-shaped shield 42 of the shielding mechanism 4 to move forward along the U-shaped groove 41 through the first push rod 64, forming a physical shield in front of the interface of the outdoor power supply body 1. On the other hand, the push plate 63 pushes the piston plate 66 in the squeezing chamber 65 to slide in a sealing manner through the second push rod 67. The gas inside is transported through a pipeline to the annular sealing airbag 52 of the sealing mechanism 5. The annular sealing airbag 52 expands within the annular frame 51, forming a compression seal on the plug cable or handheld part of the insertion interface. When protection is not required, the U-shaped shield 42 is manually pushed back along the U-shaped groove 41. The limiting plate 44 at the top of the U-shaped shield 42 slides along the limiting groove 43, pushing the third push rod 77 to drive the moving plate 73 to slide in the opposite direction. The moving plate 73 squeezes the water-absorbing sponge 72 to discharge water (the water is discharged through the drainage hole at the bottom of the groove 71). At the same time, the moving plate 73 squeezes the stop rod 75 to move down and reset along the stepped hole 74, re-clamping the push plate 63. In addition, when the protective cover 3 is closed, the U-shaped sealing ring 8 on one side is embedded in the U-shaped sealing groove 9 of the protective shell 2 to enhance the seal. The protective shell 2 is fixed to the outdoor power supply body 1 by the mounting strips 10 at the top and bottom, and the mounting holes 11 and screws. The sealing gasket 12 between the protective shell 2 and the outdoor power supply body 1 further improves the sealing of the connection part.
