Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a drop-proof power adapter. Background Technology

[0002] A power adapter is a small, portable power conversion device for electronic devices and appliances. Its structure generally consists of a casing, transformer, inductor, capacitor, control structure, and PCB board, among other components. The working principle of a power adapter is to convert AC input to DC output, making it convenient to use.

[0003] A power adapter with drop protection function is disclosed in publication number 201820115902.3 in the field of power adapter technology. The adapter includes a housing. Two sets of buffer pillars are installed on the top and bottom of the inner wall of the housing. A heat sink is installed on the other side of each buffer pillar. Heat dissipation ribs are installed on the opposite outer walls of the two sets of heat dissipation ribs. An adapter circuit board is installed between the two sets of heat dissipation ribs. A fixing rod is installed on the top and bottom of the inner wall of the housing via a connecting rod. Sleeves are slidably installed on both sides of the fixing rod. Limiting blocks are installed at both ends of the fixing rod. Movable rods are hinged to the top and bottom of the sleeves. The other end of each movable rod is hinged to a fixing block. This device buffers the adapter circuit board by inward movement of the housing, causing the spring to contract and reducing the angle between the two sets of movable rods. The movable rods convert the downward pressure on the housing into the elastic potential energy of the spring. Simultaneously, the buffer pillars further reduce the buffering effect, which helps to reduce damage to the adapter circuit board from external impacts and minimize its service life.

[0004] When this technical solution is used, it does not have a suitable guiding structure. When the shell is dropped, the angle of the drop cannot be guaranteed, which may result in the shell landing on a corner with a small contact area, increasing the pressure during the impact and causing damage to the shell. It may also result in the shell landing on its side, which may cause the direction of the landing to be misaligned with the buffering direction of the buffer structure, affecting the buffering effect and making it easy to damage the circuit board and reduce its lifespan.

[0005] Therefore, we propose a drop-proof power adapter. Utility Model Content

[0006] The present invention mainly solves the technical problem of the prior art adapter shell failing to guide the landing direction when falling, thus affecting the cushioning effect, and provides a drop-proof power adapter.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a drop-proof power adapter, comprising:

[0008] The outer casing has fixing slots on both the left and right ends. The air outlet plate and air inlet plate are respectively set on the inner wall of the fixing slots. The air outlet plate and air inlet plate are respectively set on the opposite ends of the two heat dissipation plates. The adapter circuit board is set between the two heat dissipation plates. The outer casing and the wall opposite the heat dissipation plates are provided with a buffer structure for cushioning.

[0009] Corner protectors are located at the top and bottom four corners of the housing. The corner protectors are equipped with guide components to maintain the direction of the housing's fall. The guide components include a sliding plate, a rotating cylinder, and a wing plate.

[0010] The deployment assembly is located at the connection between the rotating cylinder and the wing plate and is used to adjust the position and angle of the wing plate. The deployment assembly includes a fixed block and a rotating ring.

[0011] Furthermore, a cubical slot is provided on one side of the corner protector, and the corner protector is fixedly connected to the top and bottom corners of the outer shell through the slot.

A guide groove is provided on the side of the wing plate near the vertex of the corner protector. The inner wall of the wing plate is a hollow structure and has a storage cavity for solution flow inside. The wing plate is made of rubber.

[0012] Furthermore, the corner protector has a limiting groove on each of the three adjacent sides of the wing plate. The sliding plate is slidably connected to the inner wall of the limiting groove. An L-shaped rotating groove is provided on the side of the sliding plate away from the corner protector. A rotating pin is rotatably connected to the two adjacent walls of the rotating groove. The rotating cylinder is rotatably connected to the rotating groove on the sliding plate. The rotating cylinder has a hollow structure and is filled with an aqueous solution.

[0013] Furthermore, mounting grooves for fixing are provided at the bottom and both ends of the wing plate.

[0016] Furthermore, the outer walls of the three sides of the wing plate are provided with extension plates, which are hollow structures and connected to the inner wall of the wing plate.

[0017] Beneficial effects

[0018] This utility model provides a drop-proof power adapter. It has the following beneficial effects:

[0019] (1) The drop-proof power adapter, through the corner guards and unfolding components, can unfold the wing plates during the fall to concentrate the stress to the four corners of the shell, guide the falling direction of the shell, and prevent the shell from being misaligned with the buffer structure when it falls, thus affecting the buffering effect on the adapter circuit board inside the shell and the service life of the adapter circuit board.

[0029] Example 1: A drop-proof power adapter, such as Figure 1 and Figure 3 As shown, including

[0030] The outer casing 1 has fixing slots at both its left and right ends. The air outlet plate 2 and the air inlet plate 3 are respectively set on the inner wall of the fixing slots. The air outlet plate 2 and the air inlet plate 3 are respectively set on the opposite ends of each side of the air outlet plate 2 and the air inlet plate 3. The adapter circuit board 4 is set between the two heat dissipation plates 6. The wall surface of the outer casing 1 and the heat dissipation plate 6 is provided with a buffer structure 5 for buffering. The adapter circuit board 4 has multiple linearly arranged heat dissipation ribs at both ends and is fixedly connected to the outer wall of the heat dissipation plate 6. The air inlet plate 3 has a through heat dissipation slot in the middle. The heat dissipation slot is provided with a fan for heat dissipation.

[0031] Corner guards 7 are located at the top and bottom four corners of the outer casing 1. The corner guards 7 are provided with guide components for maintaining the falling direction of the outer casing 1. The guide components include a sliding plate 10, a rotating cylinder 11 and a wing plate 12.

[0032] The deployment assembly is located at the connection between the rotating cylinder 11 and the wing plate 12 for adjusting the position and angle of the wing plate 12. The deployment assembly includes a fixing block 14 and a rotating ring 15.

[0033] like Figure 3 and Figure 4 As shown, a cubical slot is provided on one side of the corner protector 7. The corner protector 7 is fixedly connected to the top and bottom corners of the outer shell 1 through the slot. The wing plate 12 is sleeved on the vertex of the end of the corner protector 7 away from the vertical center line of the outer shell 1. A guide groove is provided on the side of the wing plate 12 near the vertex of the corner protector 7. The inner wall of the wing plate 12 is a hollow structure and has a storage cavity for solution flow inside. The wing plate 12 is made of rubber.

[0034] When the outer shell 1 falls, the rubber material of the wing plate 12 on the corner guard 7 can come into contact with the ground. The rubber material design protects the outer shell 1, and the impact of the internal aqueous solution absorbs and buffers the stress of the fall, thus improving the protective effect of the outer shell 1.

[0035] The corner protectors 7 and wing plates 12 can protect the corners of the outer shell 1, preventing damage from impacts when the outer shell 1 is dropped, thus affecting its service life. Furthermore, the internal aqueous solution can absorb energy and cushion the impact, improving the drop protection effect.

[0036] like Figure 3 and Figure 4 As shown, the corner guard 7 has a limiting groove 9 on each of the three adjacent sides of the wing plate 12. The sliding plate 10 is slidably connected to the inner wall of the limiting groove 9. The sliding plate 10 has an L-shaped rotating groove on the side away from the corner guard 7. A rotating pin is rotatably connected to the two adjacent walls of the rotating groove. The rotating cylinder 11 is rotatably connected to the rotating groove on the sliding plate 10. The rotating cylinder 11 has a fixing hole. The rotating pin is fixedly connected to the inner wall of the fixing hole. The rotating cylinder 11 is a hollow structure and is filled with an aqueous solution.

[0037] The wing plate 12 has mounting grooves 13 for fixing at the bottom and both ends. A fixing block 14 is fixedly connected to the outer wall of the wing plate 12 at the mounting groove 13. A rotating ring 15 is provided inside the fixing block 14. The rotating cylinder 11 is fixedly connected to the inner wall of the rotating ring 15 and communicates with the inner wall of the rotating ring 15.

[0038] The fixed block 14 has a semi-circular cross-section and is fitted onto the outer wall of the mounting groove 13. The rotating ring 15 is circular and is rotatably connected to the inner wall of the fixed block 14, with the outer ring of the rotating ring 15 being tangent to the inner wall of the mounting groove 13.

[0039] When the outer shell 1 falls, the aqueous solution in the rotating cylinder 11 flows into the wing plate 12 under the inertia of the fall and drives the wing plate 12 to move upward. The upward movement of the wing plate 12 drives the rotating cylinder 11 to rotate through the rotating ring 15. The rotating cylinder 11 can then rotate within the sliding plate 10 through the rotating pin to adapt to the change of angle. The upward movement of the wing plate 12 pulls the sliding plate 10 through the rotating pin to slide within the limiting groove 9 to adapt to the change of position. Then the wing plate 12 is deployed. The impact of the wind during the fall can be concentrated in the guide grooves on the wing plate 12 at the four corners of the top of the outer shell 1, and the stress is evenly distributed to the four corners. This guides the falling direction of the outer shell 1, ensuring that the impact direction is in the same direction as the buffer structure 5, so that the buffer structure 5 can better buffer the impact.

[0040] By using the corner protectors 7 and the unfolding components, the wing plates 12 can be unfolded during descent to concentrate stress at the four corners of the outer shell 1, guiding the falling direction of the outer shell 1 and preventing the outer shell 1 from being misaligned with the buffer structure 5 when it falls, thus affecting the buffering effect on the adapter circuit board 4 inside the outer shell 1 and the service life of the adapter circuit board 4.

[0041] like Figure 2 As shown, a connecting groove 8 is provided at the middle of the top and bottom of the outer shell 1. The connecting groove 8 has a concave structure, and the concave bottom of the connecting groove 8 is located at the center of the top and bottom of the outer shell 1.

[0042] The concave design of the connecting groove 8 can guide the stress of the outer shell 1 when it falls to the bottom of the concave area, and then concentrate the stress to the center of the outer shell 1, thereby further ensuring the direction of the outer shell 1 when it falls.

[0043] The design of the connecting groove 8 further ensures the falling direction of the outer shell 1, preventing the outer shell 1 from being misaligned with the buffer structure 5 when it falls, thus affecting the buffering effect on the adapter circuit board 4 inside the outer shell 1 and the service life of the adapter circuit board 4.

[0044] Example 2: Based on Example 1, with reference to Figure 5The outer walls of the wing plate 12 on three sides are provided with extension plates 16. The extension plates 16 are hollow structures and are connected to the inner walls of the wing plate 12. The cross-section of the extension plates 16 is L-shaped and is located between two adjacent mounting grooves 13. The material of the extension plates 16 is waterproof membrane.

[0045] When the aqueous solution enters the wing plate 12, it can be dispersed and filled into the extension plate 16, thus expanding the extension plate 16, increasing the area of ​​the wing plate 12, thereby increasing air resistance and reducing the falling speed.

[0046] The extension plate 16 can reduce the falling speed, reduce the impact on the outer shell 1, and improve the drop protection effect.

[0047] The working principle of this utility model is as follows: When the outer shell 1 falls, the aqueous solution in the rotating cylinder 11 flows into the wing plate 12 under the inertia of falling and drives the wing plate 12 to move upward. Through the rotating ring 15, the rotating cylinder 11 and the rotating pin in the sliding plate 10, the wing plate 12 is unfolded to the top four corners of the outer shell 1, concentrating the stress at the top four corners of the outer shell 1 and guiding the falling direction of the outer shell 1. At this time, the wing plate 12 at the bottom is sleeved at the corner guard 7, which can cushion the outer shell 1 when it lands.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
