Parking lock: A parking lock is a mechanical device that prevents others from occupying your car's parking space and allows you to park your car wherever you go. The installation position of the parking lock is generally installed at 1/3 of the middle entrance of the parking space, and the installation conditions are required to be on a cement flat ground. Functionally divided into: manual parking lock, remote parking lock. Structural shapes are divided into: O-type parking lock, K-type parking lock, T-type parking lock, X-type parking lock, A-type (also called triangle) D-type, U-type, F-type, square parking lock and so on. The installation position of the parking lock is generally installed at 1/3 of the middle entrance of the parking space, and the installation conditions are required to be on a cement flat ground. If the parking space in the community is tiled or colored tiles, the thickness of the bricks is required to be more than 5 cm. If the requirements are not met, the cement prefabricated ground can be installed in advance. The prefabricated area should be determined according to the shape and size of the parking lock. Installation tools: power cord with dozens of meters, electric drill (drill bit 12 or 14), hammer, nut sleeve, tape measure, expansion screw (m10*10 or m10*8), etc. Use a tape measure to measure the placement and then straighten it. After connecting the power supply, use an electric drill to align with the screw hole and lightly make a mark, then use the unlocker to align with the mark and drill a hole. The electric drill should be held straight, and the depth should be about the same as the length of the screw. Re-align the lock, align the screw and insert it with a hammer, and finally tighten it with a nut sleeve. The remote control parking lock is actually a complete automatic mechanical equipment. Must have: control system, drive system, power supply. Therefore, the volume problem and the service life problem of the power supply cannot be avoided. In particular, the power supply is the bottleneck in the development of remote control parking locks. Because the driving current is relatively large, the general remote control parking locks are powered by lead-acid maintenance-free batteries, and everyone knows that batteries have self-discharge problems. It must be recharged within a month, otherwise it will be scrapped soon.
