Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with multi-mode heat dissipation. Background Art

[0002] With the advancement of technology, various portable electronic devices such as laptops, tablets, and smartphones are playing an increasingly important role in people's daily lives. These devices rely on power adapters to provide the necessary power when charging. Traditional power adapters primarily consist of components such as an input plug, transformer, rectifier, filter circuit, and output port. They convert alternating current (AC) into direct current (DC) suitable for electronic devices.

[0003] In the design of a power adapter, since electronic components generate heat during operation, if the heat is not dissipated in time, the temperature will rise, which will in turn affect the working efficiency and life of the power adapter. Therefore, heat dissipation becomes a crucial link. The structure is as shown in the Chinese utility model "A power adapter with multiple protection structures" with announcement number CN221305736U, which includes a shell and an adapter. The adapter is arranged inside the shell, and a buffer pad fixedly connected to the shell is provided at the corner of the adapter. The top and bottom of the shell are both provided with air holes, and a connector hole is provided at one end of the shell. A connector is provided at one end of the adapter; a storage cavity is provided at the other end of the shell, and a through hole is provided between the storage cavity and the interior of the shell. A cable is provided at one end of the adapter, and a take-up shaft is rotatably connected to the storage cavity. A wire groove is provided inside the take-up shaft, and a wire reel is wound in the storage cavity. A plug is provided at the end of the wire reel, and a fixing ring is fixedly connected to the shell at the position of the plug. The air hole is also called a heat dissipation port.

[0004] In the above patent, although heat can be effectively dissipated through the heat dissipation vents when in use, the heat dissipation vents are in an open state when not in use, which makes it easy for dust, water vapor and other impurities in the external environment to enter the power adapter through the heat dissipation vents. Over time, these impurities may cause corrosion, short circuits and other problems in the components on the internal circuit board, thereby shortening the service life of the power adapter and may even cause safety hazards.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a multi-mode heat dissipation power adapter, comprising a power adapter body, the power adapter body comprising a protective shell, one end of the protective shell having a plug interface, a side surface of the protective shell having a notch, and a plurality of heat dissipation ports formed in the notch;

[0008] The plurality of heat dissipation ports are arranged equidistantly in the slot, the slot is provided with a movable baffle, the movable baffle has a plurality of through slots corresponding to the heat dissipation ports, two sliding slots are provided on both sides of the slot on one side of the protective shell, a slider is provided for sliding in the sliding slot, the slider extends from the outer side of the protective shell and is connected to the control panel, connecting through slots connected to the sliding slots are respectively provided on both side surfaces of the inner wall of the slot, connecting rods are respectively provided on both side surfaces of the movable baffle, and the connecting rods pass through the connecting through slots and are connected to the slider.

[0009] As a further solution of the present invention: the interior of the connecting slot has a space for the connecting rod to move laterally a certain distance, wherein when the slot is aligned with the heat dissipation port, the connecting rod abuts against one side of the connecting slot.

[0010] As a further solution of the present invention: a side surface of the protective shell is provided with a snap mechanism located at one end of the control panel, the snap mechanism comprising two side panels and a snap plate axially connected between the two side panels, the snap plate having a first oblique snap block at one end facing the control panel and a first spring connected between the other end and the protective shell;

[0011] The control plate has a second oblique block matching the first oblique block at one end facing the buckle mechanism, and the oblique surfaces of the first oblique block and the second oblique block are opposite, so that when the control plate moves laterally toward the buckle mechanism, the second oblique block pushes the first oblique block and forms mutual abutment.

[0012] As a further solution of the present invention: an inner cavity groove is opened on a side wall of the sliding groove close to the buckle mechanism, and a second spring is connected between the inner wall of the inner cavity groove and the sliding block.

[0013] As a further solution of the present invention: the width between the two through grooves is greater than the width of the heat dissipation port.

[0014] As a further solution of the present invention: the surfaces of the control plate and the card plate are both provided with anti-slip protrusions.

[0015] As a further solution of the present invention: the movable baffle is further provided with a mounting groove, in which a filter plate is installed.

[0016] Compared with the existing technology, the beneficial effects of this technical solution are:

[0017] The movable baffle can be moved to one side by pushing the control panel, so that the through slot of the movable baffle and the heat dissipation port are staggered with each other, thereby forming a covering effect for the heat dissipation port, preventing dust, water stains and other impurities in the external environment from entering the power adapter body through the heat dissipation port when not in use, causing corrosion and short circuit of electronic components on the internal circuit board. This ensures the heat dissipation effect during use while extending the service life of the power adapter body.

[0018] When the power adapter body is not in use and the control panel needs to be moved horizontally to drive the movable baffle, the second oblique clamping block abuts against the first oblique clamping block to fix the position of the control panel and the movable baffle, thereby preventing the movable baffle from moving on its own during carrying, resulting in insufficient covering effect on the heat dissipation port;

[0019] When the power adapter body is in use and the heat dissipation vent needs to be in a normally open state, the card plate located at one end of the first spring is pressed to cause one end of the first oblique card block to flip upward, so that the first oblique card block is separated from the second oblique card block. At this time, the slider is pushed by the second spring, thereby driving the control panel, the connecting rod and the movable baffle to move, so that the through groove is aligned with the heat dissipation vent, so that the heat emitted by the power adapter body in use can be dissipated through the heat dissipation vent, thereby facilitating the switching of the opening and closing states of the heat dissipation vent.

[0020] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-5 A multi-mode heat dissipation power adapter includes a power adapter body 1, the power adapter body 1 includes a protective shell 2, one side end of the protective shell 2 has a plug interface 3, a side surface of the protective shell 2 is provided with a notch 21, and a plurality of heat dissipation ports 22 are provided in the notch 21;

[0031] Preferably, multiple heat dissipation ports 22 are arranged equidistantly in the slot 21, and the slot 21 is provided with a movable baffle 4, which has multiple through slots 41 corresponding to the heat dissipation ports 22. Two sliding slots 23 are provided on one side of the protective shell 2 on both sides of the slot 21, and a slider 5 is provided to slide in the sliding slot 23. The slider 5 extends to the outer side of the protective shell 2 and is connected to the control panel 51. Connecting through slots 24 connected to the sliding slots 23 are respectively provided on both sides of the inner wall of the slot 21, and connecting rods 42 are respectively provided on both sides of the movable baffle 4, and the connecting rod 42 passes through the connecting through slot 24 and is connected to the slider 5.

[0032] By pushing the two control panels 51 to move sideways, the slider 5 is driven to slide in the sliding groove 23. The slider 5 drives the movable baffle 4 through the connecting rod 42, so that the multiple through grooves 41 opened on the movable baffle 4 are staggered with the multiple heat dissipation ports 22 opened in the slot 21, thereby covering the heat dissipation ports 22, preventing dust, water stains and other impurities in the external environment from entering the power adapter body 1 through the heat dissipation ports 22 when not in use, causing corrosion, short circuit and other problems of the electronic components on the internal circuit board. This ensures the heat dissipation effect during use while improving the service life of the power adapter body 1.

[0033] Preferably, the connecting slot 24 has a space inside for the connecting rod 42 to move laterally by a certain distance, wherein when the slot 41 is aligned with the heat dissipation port 22, the connecting rod 42 abuts against one side of the connecting slot 24;

[0034] When the power adapter body 1 is in use, the movable baffle 4 is controlled to move horizontally by pushing the control panel 51, so that the multiple through slots 41 of the movable baffle 4 are aligned with the multiple heat dissipation ports 22, so that the heat generated during operation can be dissipated from the heat dissipation ports 22 to the external environment, ensuring the heat dissipation effect and preventing the operating temperature of the power adapter body 1 from being too high. When the through slots 41 are aligned with the heat dissipation ports 22, the connecting rod 42 will abut against one side of the connecting through slot 24, thereby starting the active positioning function. Specifically, when the movable baffle 4 is controlled to move horizontally, when the connecting rod 42 abuts against the connecting through slot 24, it means that the through slot 41 and the heat dissipation ports 22 are aligned.

[0035] Preferably, a snap mechanism 6 is provided on one side of the protective shell 2 and is located at one end of the control panel 51. The snap mechanism includes two side panels 61 and a snap plate 62 directly pivotally connected to the two side panels 61. The snap plate 62 has a first oblique snap block 63 at one end facing the control panel 51, and a first spring 64 is connected to the protective shell 2 at the other end.

[0036] The control plate 51 has a second oblique block 52 on one end facing the buckle mechanism 6, which matches the first oblique block 63. The first oblique block 63 and the second oblique block 52 have opposing oblique surfaces, so that when the control plate 51 moves laterally toward the buckle mechanism 6, the second oblique block 52 pushes the first oblique block 63 and forms a mutual abutment.

[0037] When the power adapter body 1 is not in use, the movable baffle 4 is controlled to move horizontally by pushing the control panel 51 to cover the heat dissipation port. During the movement, the second oblique block 52 of the control panel 51 has its oblique surface abutted against the oblique surface of the first oblique block 63, and the card plate 62 is rotatably connected to the two side plates 61, so that as the control panel 51 and the second oblique block 52 gradually move horizontally, one end of the card plate 62 can be rotated upward by pushing the first oblique block 63, while the other end rotates downward accordingly, and squeezes the first spring 64 between the protective shell 2, so that when the second oblique block 52 passes over the first oblique block 63, the first spring 64 pushes one end of the card plate 62 upward, causing the end of the first oblique block 63 to flip down and reset, thereby causing the first oblique block 63 and the second oblique block 52 to abut against each other, so as to fix the position of the control panel 51 and the movable baffle 4, and prevent the movable baffle 4 from moving on its own during carrying, resulting in insufficient covering effect on the heat dissipation port 22.

[0038] Preferably, an inner cavity groove 25 is formed on one side wall of the sliding groove 23 close to the buckle mechanism 6, and a second spring 7 is connected between the inner wall of the inner cavity groove 25 and the slider 5;

[0039] When the power adapter body 1 is in use, the card plate 62 is pressed at one end of the first spring 64, so that one end of the first oblique card block 63 flips upward, so that the first oblique card block 63 is separated from the second oblique card block 52. At this time, the second spring 7 between the inner cavity groove 25 and the slider 5 pushes the slider 5 by releasing elastic potential energy, thereby driving the control plate 51, the connecting rod 42 and the movable baffle 4 to move, so that the through groove 41 is aligned with the heat dissipation port 22, so that the heat emitted by the power adapter body 1 in use can be dissipated through the heat dissipation port 22.

[0040] Preferably, the width between the two through slots 41 is greater than the width of the heat dissipation opening 22 to ensure that the heat dissipation opening 22 can be completely covered.

[0041] Preferably, the surfaces of the control panel 51 and the card plate 62 are provided with anti-slip protrusions 8 to facilitate control of the control panel 51 and the card plate 62 and avoid slipping;

[0042] Furthermore, a mounting groove is provided on the movable baffle 4, in which a filter plate 9 is installed. The filter plate 9 can filter dust and impurities in the air when the through groove 41 is aligned with the heat dissipation port 22, thereby further preventing dust from entering the interior of the power adapter body 1.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
