[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0029] The utility model embodiment provides a charger, such as Figure 1 and Figure 2 As shown, the charger includes a housing 10, a plug pin 20 and a support base 30.

[0030] A circuit board 40 is disposed in the housing 10 .

[0031] The pin 20 is fixed to the bottom of the housing 10 and is electrically connected to the circuit board 40. The pin 20 can be used to transmit electrical energy. Externally, the pin 20 can be plugged into a power supply device to obtain electrical energy. Internally, the pin 20 can transmit the electrical energy obtained from the power supply device to the circuit board 40.

[0032] The support base 30 can be detachably mounted and sleeved on the pin 20. The support base 30 can be sleeved on the pin 20 and can also be removed from the pin 20. The charger as a whole can be placed on the desktop through the support base 30.

[0033] By fixing the pin 20 to the bottom of the shell 10 and providing a support base 30, the support base 30 can be disassembled and sleeved on the pin 20. When the charger needs to be used, the support base 30 is removed from the pin 20. When the charger is not in use, the support base 30 is sleeved on the pin 20 to prevent the pin 20 from being subjected to external wear and collision, thereby improving the service life of the charger. At the same time, since the pin 20 is fixed on the shell 10, the pin 20 can be electrically connected to the circuit board 40 with a simpler electrical connection structure, and the requirements for the electrical connection structure are relatively low.

[0034] Specifically, in the prior art, conductive sheets are usually provided to connect the pins 20 and the circuit board 40 respectively, and the pins 20 are rotated and stored by the rotating shaft. In order to ensure that the pins 20 can still be electrically connected to the circuit board 40 through the conductive sheets after rotating to the charging position, the structural design requirements of the conductive sheets are higher. In the present application, the pins 20 are fixed to the housing 10 and can be directly connected to the electrical connection structure such as the conductive sheets, and the structural design requirements of the conductive sheets are lower.

[0035] refer to Figure 1 and Figure 2 In this embodiment, a clamping structure 31 is provided in the support base 30, and the plug pin 20 can be inserted and clamped in the clamping structure 31. The clamping structure 31 allows the support base 30 to be tightly sleeved on the plug pin 20, and the support base 30 is not easy to fall off from the plug pin 20.

[0036] Specifically, the clamping structure 31 includes a first clamping arm 311 and a second clamping arm 312 , and a clamping block 313 protruding toward the other clamping arm is provided on the first clamping arm 311 and / or the second clamping arm 312 .

[0037] When the first clamping arm 311 or the second clamping arm 312 is provided with a clamping block 313 protruding toward the other clamping arm, the pin 20 is inserted between the clamping block 313 and the other clamping arm. Specifically, when the first clamping arm 311 is provided with a clamping block 313 protruding toward the second clamping arm 312, the pin 20 is inserted between the clamping block 313 and the second clamping arm 312; when the second clamping arm 312 is provided with a clamping block 313 protruding toward the first clamping arm 311, the pin 20 is inserted between the clamping block 313 and the first clamping arm 311.

[0038] When the first clamping arm 311 and the second clamping arm 312 are both provided with a clamping block 313 protruding toward the other clamping arm, the pin 20 is inserted and clamped between the two clamping blocks 313 .

[0039] By arranging the first clamping arm 311 and the second clamping arm 312 in the support base 30, the gap between the first clamping arm 311 and the second clamping arm 312 provides a space for inserting the pin 20. In addition, by arranging the clamping block 313 on the first clamping arm 311 and / or the second clamping arm 312, the contact area between the pin 20 and the first clamping arm and the second clamping arm can be reduced to a certain extent, and the support base 30 can be quickly mounted on the pin 20.

[0040] refer to Figure 2The bottom of the support seat 30 is provided with a limiting groove 32 corresponding to the position of the clamping structure 31. After the plug pin 20 is inserted and clamped in the clamping structure 31, it is at least partially accommodated in the limiting groove 32. The limiting groove 32 plays a certain guiding role in the process of the plug pin 20 being inserted into the support seat 30. At the same time, when the plug pin 20 shakes relative to the support seat 30, the groove side wall of the limiting groove 32 abuts against the plug pin 20 to limit the shaking angle of the plug pin 20.

[0041] In other embodiments, the clamping structure 31 may be a clamping groove provided at the bottom of the support seat 30, the pin 20 is inserted into the clamping groove, and the pin 20 abuts against the side wall of the clamping groove, so that the support seat 30 can be sleeved on the outer periphery of the pin 20 to prevent the pin 20 from being damaged and collided.

[0042] refer to Figure 2 At least one magnetic adsorption member 50 is provided on the support base 30, and the magnetic adsorption member 50 is used to form a magnetic adsorption surface on the end surface of the support base 30. When the charger is not needed for charging, the charger can be adsorbed and positioned on a desktop that can be magnetically attracted to the magnetic adsorption member 50 through the magnetic adsorption member 50 on the support base 30; when the charger is needed for charging, the support base 30 can be removed from the pin 20 and placed on a desktop that can be magnetically attracted to the magnetic adsorption member 50, which is easy to find and prevents the support base 30 from being lost.

[0043] The number of magnetic adsorbents 50 can be one, two or more, and the user can set it according to actual needs. In this embodiment, two magnetic adsorbents 50 are arranged in the support base 30, and a magnetic adsorption surface is formed on the end surface of the support base 30 to stably adsorb and position the charger on the desktop.
