The invention discloses a lock catch assembly of a supermarket trolley. The assembly comprises a lock shell body, a lock catch and a key matched with the lock catch. One end of the lock catch is a connecting part, the other end of the lock catch is a driving part, a lower end between the connecting part and the driving part is a supporting protruding part, a cam containing hole is formed in the middle of the driving part on the right side of the supporting protruding part, a U-shaped opening is formed above the driving part, a first lock hook part is arranged on the left side of the U-shaped opening and a second lock hook part is arranged on a right side. In a coin manual state and in a mobile payment state, a motor only needs to rotate by half a circle to complete unlocking, the number ofrotating turns of the motor is reduced, energy consumption of the motor is decreased, a service life of a battery in the automatic lock is prolonged, and an newly added lock catch and key structure is improved in a using process so that the lock catch and key structure mainly depends on spring resetting during resetting, a response speed is high, and response time is short.
