Description

Ground lock and management system Technical Field The invention relates to a ground lock and to a management system provided with such a ground lock. Background The ground lock is mainly used as a parking space ground lock, but is not limited to a parking space ground lock, and may be defined as a mechanical device installed on the ground and having a lifting lock portion. The types of lifting locks are relatively large, and one type of lifting lock is a lock which can lift based on rotation (swing). The lock part is in the operating condition of ground lock after rising, and the lock part is the working element of keeping off the car, receives the impact of vehicle wheel or frame under the operating condition easily, and the mode of the damage or damage to ground lock in order to solve this impact at present mainly has three kinds, and one is to adopt integrated structure, and the lock part in the integrated structure is the lock arm that goes up and down in vertical direction, and the lock arm contains in a lifting unit, generally includes motor and drive mechanism, and drive mechanism is used for converting the rotary motion of motor into the up-and-down motion of lock arm. Further, a rubber pad is provided above the locking arm, for example, for directly receiving the impact. The direction of the impact force born by the mode is often inconsistent with the movement direction of the lock part, and under the condition of more bearing the impact force, the direction of the impact force is basically perpendicular to the movement direction of the lock part, and the seat and the shell of the ground lock are easy to damage or damage although the transmission part can be effectively protected. The second way is to directly use a relatively high-strength component to make the ground lock, which is simple and direct, but the ground lock needs to consider the connection strength between the ground lock and the ground in addition to the self strength, and in more applications, the strength of the ground lock is not high, i.e. the ground lock strength is lower than that of a vehicle chassis under the conventional condition, so that the ground lock is usually insufficient to damage the vehicle chassis. The improvement of the lock by means of self-reinforcement is currently mainly achieved in that, for example, the housing part of the lock does not undergo plastic deformation when the vehicle is subjected to rolling, but rather in the blocking actuating part. The third mode can be understood as a dodge type, and can be called a smart parking spot lock because the state of the lock portion can be controlled by recognizing the force applied by, for example, an impact. The part for keeping off the car in this kind of form is the swing arm, and when the swing arm of intelligent parking stall lock received the striking, the sensor of corresponding setting can monitor the power that the swing arm received, if the power of monitoring is greater than the setting value, the swing arm can descend to rise again after several seconds. This approach deviates substantially from the original design requirements of the ground lock, although people will consciously avoid the collision of the vehicle with the ground lock during use, if the vehicle owner realizes that the collision will not cause damage to the vehicle, and can break away from the constraint of the ground lock, the management of the parking spaces provided with the ground lock will become uncontrollable. In view of this, the emphasis of current research and development is placed on avoiding or reducing ground lock damage while not disengaging, for example, the vehicle from the ground lock. In chinese patent CN221398759U, a ground lock with a flexible transmission assembly is thus proposed, by means of which the "flexibility" of the ground lock dampens the tile assembly of the ground lock when it is subjected to e.g. a vehicle impact, in order to reduce damage or breakage to the power or transmission components. The flexible transmission used in this patent document should be a steel strand, the main purpose of which is to extend the power for driving the opening and closing of the sign assembly to a relatively remote position from the ground lock, for example by means of the steel strand, so as to avoid failure of the ground lock after flooding. The flexible transmission member itself has a certain resistance against rigid impact, while the driving bushing of the card assembly is mounted on the driving spindle via the first elastic restoring member, although it is not described in this patent document whether the first elastic restoring member has the ability to provide a buffer when the card assembly is impacted, the inventor believes that the first elastic restoring member has a certain buffer capacity in the reverse restoring direction. It should be appreciated that the mechanism is a collection of members having a defined movement relationship, and the presence of th
