[0001] The utility model relates to electronic equipment accessory technical field, especially a wireless charger. BACKGROUND

[0002] With the development of wireless charging technology, the design of wireless chargers on the market is gradually diversified. In addition to the traditional flat wireless charging board, wireless chargers with stand design have become popular. Such wireless chargers usually have a certain support structure and can provide stable placement of the device while charging.

[0003] However, when the support angle of the stand changes, the center of gravity of the device as a whole will shift, affecting the stability of the support. At the same time, as the charging power continues to rise, to effectively solve the heat dissipation problem, the design of the heat dissipation module becomes more complex. The complex heat dissipation module causes the center of gravity of the wireless charger to shift significantly to the heat dissipation module area. The current stand design of the wireless charger is too small and simple, and cannot be optimized for center of gravity changes and multi-angle support requirements, making the charger difficult to maintain stability in multiple scenarios and prone to tipping over. Not only does this reduce the user experience, but it can also cause damage to the charging device. SUMMARY
