Description

TECHNICAL FIELD

[0001] The utility model relates to the field technology of vehicle-mounted accessories, especially to a vehicle-mounted supporting device, a baby monitor and an electronic product support. BACKGROUND

[0002] During the driving process of a vehicle, the main attention of a driver is on the observation of road conditions and the control of the vehicle. In the case of accompanying a baby going out, the driver needs to pay real-time attention to the baby's riding situation while driving safely. Therefore, a monitoring device or an observation mirror needs to be installed in the vehicle to facilitate the driver to learn about the baby's riding situation in real time. In the case of accompanying a passenger going out, a rear headrest support can be installed between the two supporting rods of the headrest of the vehicle. After the rear headrest support is installed with a clamp, the clamp is used to fix electronic products such as a mobile phone and a tablet computer of the passenger, so as to reduce the fatigue of the passenger caused by holding the electronic products for a long time. The passenger can enjoy the fun of movies, music and electronic reading through the electronic products, so as to solve the boredom during the driving process of the vehicle.

[0003] In the prior art, the monitoring device or the observation mirror is fixed by means of a strap. The monitoring device or the observation mirror is tied and fixed on the headrest. The position and the angle of the monitoring device or the observation mirror are difficult to adjust. The strap will block the line of sight, and the use is relatively inconvenient. The monitoring device or the observation mirror or the clamp can also be fixed by means of a rear headrest support. The rear headrest support includes a clamping part clamped on a metal rod of a rear headrest, a connecting arm and a ball head. After the monitoring device or the observation mirror or the clamp is installed on the ball head, only the front and rear adjustment can be realized under this structure. For the application scene of the monitoring device or the observation mirror, different drivers have different heights, and it is impossible to adapt to drivers of different heights. The versatility is poor. For the application scene of the clamp, the adjustment direction is too limited, and the use comfort is poor.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. UTILITY MODEL CONTENTS
