Problems solved by technology

[0004] However, the current ISOFIX system on the market is easy to loosen during use, which is likely to cause safety accidents and has low safety performance.
At the same time, because the ISOFIX system is installed in the car, maintenance is inconvenient, resulting in a certain waste of resources; and the locking block of the release device is very important, but the strength and hardness of the locking block are average, resulting in a short service life of the locking block , thereby affecting the service life of the entire system

The automobile child safety seat ISOFIX system is convenient to maintain and good in safety performance, the comprehensive performance of the locking block is good, and the service life of the whole system is prolonged.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an automobile child safety seat, in particular to an ISOFIX system for an automobile child safety seat. Background technique [0002] The full name of ISOFIX is "International Standards Organization FIX", which means in Chinese: International Organization for Standardization Fixtures. ISOFIX refers to a system in which a child restraint system is connected to a vehicle. It is a new standard for placing child seats in cars. This standard is being accepted by many automakers. [0003] ISOFIX, as a new standard for placing child seats in cars, is designed to make the installation of child seats quick and easy, and the rigid connection will make it safer. The child seat equipped with ISOFIX can be easily fixed to the ISOFIX interface of the car to increase safety. [0004] However, the ISOFIX system currently on the market is easy to loosen during use, which is likely to cause sa...
