Description

Technical Field

[0001] This utility model relates to the field of vehicle chargers, and in particular to a heat dissipation structure for a vehicle charger. Background Technology

[0002] A car charger is an accessory that uses a car battery to charge portable electronic devices. Due to its limited internal space, a car charger's internal electronic components are difficult to heat dissipate, which can easily damage these components and reduce the charger's lifespan. To ensure that the internal components of a car charger do not overheat, a heat dissipation structure is usually incorporated into the charger to achieve effective heat dissipation.

[0003] Existing vehicle chargers primarily use finned heat dissipation structures, with fins running through the charger's casing to achieve efficient heat dissipation. However, this type of heat dissipation structure has fixed fins that cannot be disassembled. When dust or dirt accumulates on the fin surface, it cannot be cleaned quickly, making operation extremely inconvenient. Furthermore, the fixed fins hinder maintenance work, resulting in poor ease of operation. Utility Model Content

[0009] Preferably, the clamping assembly includes a first spring, a second spring, a first semi-cylinder, a second semi-cylinder, and a limiting block. The first spring and the second spring are disposed on the elastic connecting piece. The first semi-cylinder and the second semi-cylinder are respectively fixed on the first spring and the second spring, and the first semi-cylinder and the second semi-cylinder form a complete clamping cylinder. The two limiting blocks are respectively disposed at the lower ends of the first semi-cylinder and the second semi-cylinder.

[0010] Preferably, the clamping assembly further includes a clamping sleeve, a clamping hole, and an anti-slip protrusion.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-4 As shown, a heat dissipation structure for a vehicle charger includes a charger body 1, a plug-in portion 2 at the lower end of the charger body 1, a connection hole 3 on the charger body 1, and a heat dissipation structure 4 installed on the exterior of the charger body 1. A USB interface 5 is provided at the end of the charger body 1, and a Type-C interface is also provided on the charger body 1. A metal abutment post is provided at the lower end of the plug-in portion 2, and an elastic contact piece is provided on the plug-in portion 2.

[0016] When using the car charger, the heat dissipation structure 4 is installed on the outside of the charger body 1. The heat dissipation part of the heat dissipation structure 4 is inserted through the connection hole 3, and the plug part 2 is connected to the corresponding socket on the car. The circuit is connected through the metal abutment post and the elastic contact piece, so that the car charger can be powered on and used. During use, the corresponding data cable connector is connected using the USB interface 5 or Type-C interface on the charger body 1. The other end of the data cable is connected to electronic devices such as mobile phones, thereby achieving the effect of car charging. During the car charging process, the internal components of the charger body 1 will generate heat. The heat is dissipated through the heat dissipation structure 4, which can ensure that the temperature of the internal components of the charger body 1 does not become too high, ensuring the normal use of the car charger. When needed, the heat dissipation structure 4 can be quickly disassembled for cleaning or maintenance. The structure is simple and the operation is convenient and quick.

[0017] According to the above implementation scheme, the heat dissipation structure 4 includes an elastic connecting piece 401, a heat dissipation fin 402 and a clamping component 403. The elastic connecting piece 401 and the heat dissipation fin 402 are fixedly connected, and the elastic connecting piece 401 is sleeved on the charger body 1. The heat dissipation fin 402 passes through the connection hole 3 on the charger body 1, and the clamping component 403 is disposed on the elastic connecting piece 401.

[0018] When installing the heat dissipation structure 4, bend the elastic connecting piece 401 and wrap it around the charger body 1, so that the heat dissipation fins 402 are inserted into the connecting hole 3. Then, use the clamping component 403 to fix the elastic connecting piece 401. During use, the heat dissipation fins 402 conduct heat from inside the charger body 1 to the outside air, achieving efficient heat dissipation. When needed, the heat dissipation structure 4 can be disassembled using the clamping component 403 for quick cleaning or maintenance. After the operation, it can be reinstalled for use.

[0019] The clamping assembly 403 includes a first spring piece 4031, a second spring piece 4032, a first semi-cylinder 4033, a second semi-cylinder 4034, and a limiting block 4035. The first spring piece 4031 and the second spring piece 4032 are disposed on the elastic connecting piece 401. The first semi-cylinder 4033 and the second semi-cylinder 4034 are respectively fixed on the first spring piece 4031 and the second spring piece 4032, and the first semi-cylinder 4033 and the second semi-cylinder 4034 form a complete clamping cylinder. The two limiting blocks 4035 are respectively disposed at the lower ends of the first semi-cylinder 4033 and the second semi-cylinder 4034. The clamping assembly 403 also includes a snap-fit ​​sleeve 4036, a snap-fit ​​hole 4037, and an anti-slip protrusion 4038. The snap-fit ​​hole 4037 is formed on the snap-fit ​​sleeve 4036, and the snap-fit ​​sleeve 4036 is fitted onto the snap-fit ​​cylinder through the snap-fit ​​hole 4037. The anti-slip protrusion 4038 is fixed at the upper end of the snap-fit ​​sleeve 4036.

[0020] During the installation of the heat dissipation structure 4, after the elastic connecting piece 401 is wrapped around the charger body 1, the first spring piece 4031 and the second spring piece 4032 approach each other, and the first semi-cylinder 4033 and the second semi-cylinder 4034 come together. A force is applied to make the first semi-cylinder 4033 and the second semi-cylinder 4034 come together to form a complete snap-fit ​​cylinder. Then, the snap-fit ​​sleeve 4036 is put on the snap-fit ​​cylinder so that the snap-fit ​​cylinder is snapped into the snap-fit ​​hole 4037. The fingers pinch the anti-slip protrusion 4038 to apply a downward force to the snap-fit ​​sleeve 4036 until the snap-fit ​​sleeve 4036 abuts against the limit stop 4035, thereby completing the connection and locking work. At this time, under the elastic action of the first spring piece 4031 and the second spring piece 4032, the two semi-cylinders have a tendency to open outward, thereby forming an elastic pressing effect with the snap-fit ​​sleeve 4036, ensuring the installation stability of the heat dissipation structure 4. If it is necessary to disassemble the heat dissipation structure 4, the snap-fit ​​sleeve 4036 is lifted by the anti-slip protrusion 4038, so that the snap-fit ​​sleeve 4036 is detached from the snap-fit ​​cylinder, and then the elastic connecting piece 401 is removed to perform the corresponding operation.

[0021] It should be noted that the heat dissipation structure 4 can efficiently dissipate heat from the vehicle charger, ensuring the stable operation of the internal components. A connection hole 3 is provided on the charger body 1. The heat dissipation structure 4 consists of an elastic connecting piece 401, heat dissipation fins 402, and a clamping assembly 403, which can realize the quick assembly and disassembly of the heat dissipation structure 4, facilitate the cleaning of the heat dissipation fins 402, and facilitate maintenance. The clamping assembly 403 is provided with a first semi-cylinder 4033 and a second semi-cylinder 4034. The two semi-cylinders are combined to form a clamping cylinder, which is used in conjunction with the clamping sleeve 4036 to quickly clamp and limit the two semi-cylinders, realize the fixed installation of the elastic connecting piece 401, and facilitate the quick disassembly. The structure is simple and the operation is convenient and quick.

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.
