The invention belongs to the technical field of new energy automobiles, particularly relates to a driving motor for a new energy automobile and a method thereof, and aims to solve the problems that in the prior art, a heat dissipation structure mostly adopts a single-direction blowing design, airflow coverage is uneven, wiring terminal protection mostly adopts an integral closed structure, wiring operation is tedious, and mistaken touch short circuit is likely to occur. According to the scheme, the motor comprises a heat dissipation cover and a motor body arranged in the heat dissipation cover, a motor front end cover is arranged on one side of the motor body, an output end is arranged in the middle of the side, away from the motor body, of the motor front end cover, and a wiring terminal is arranged on the side, away from the motor front end cover, of the motor body; the heat dissipation cavity is formed in the left side of the interior of the heat dissipation cover; according to the invention, heat dissipation airflow uniformly covers the motor main body, the problem of local overheating is solved, and wiring node loosening caused by automobile vibration or external force pulling is effectively avoided.

The utility model provides a detachable data acquisition device for an electric energy meter, which relates to the field of electric energy meter acquisition and comprises a shell assembly and a circuit board. Rapid clamping and bolt fixing of the top shell and the bottom shell are achieved, the mounting and dismounting time is remarkably shortened, the maintenance efficiency is improved, the connecting component adopts a double fixing mode of connecting bolts and limiting, the bolts are connected through internal threads to ensure the connecting safety, the bolts are further prevented from loosening through a conical clamping structure of the limiting body, and the safety is improved. The protection reinforcing ribs on the outer sides of the top shell and the bottom shell are integrally designed, the impact resistance and deformation resistance of the shells are remarkably improved, the service life of equipment is prolonged, different types of electric energy meter interfaces are compatible through the standardized clamping and threaded connection design, the customization development cost is reduced, and the practicability is high. Meanwhile, the production process is simplified.

The utility model discloses a crystal head theftproof plug device, including the shell and key, the shell inside is established with the jack of crystal head plug, the upper end of one end shell is provided with the press piece, the other end shell inside is provided with both sides and is provided with the slot, and both sides the slot between is provided with the plug -in block, the plug -in block top is provided with the lock catch structure, the press piece is restricted to press down after the plug -in block inserts the shell, and is unlocked through the key plug -in lock catch structure pull -out plug -in block. Adopt the utility model structure, can realize further guarantee network connection stability and security.

The utility model discloses a wiring terminal with a locking switch. The wiring terminal comprises a housing, a conductive assembly and at least one control handle. The conductive assembly is arranged in the shell, the control handle is coupled to a first end face of the shell, and the control handle can be switched between a pressing state and a lifting state; the device is characterized in that a locking switch capable of moving between a first position and a second position is arranged on the shell, and when the locking switch is located at the first position, the locking switch is pressed above the control handle in a downward pressing state; when the locking switch moves from the first position to the second position, the control handle can be manually lifted; and the risk of disconnection caused by accidental operation or external force is reduced.

This utility model belongs to the field of balancing valve technology and discloses an adjustable balancing valve, including a valve body. The output end of the valve body is fixedly connected to a connecting flange, and the input end of the valve body is fixedly connected to a positioning flange. A sealing assembly is installed inside the positioning flange. A locking assembly is rotatably connected to the positioning flange near the connecting flange on the outside of the valve body. Several connecting assemblies, evenly distributed on the outside of the valve body, are connected inside the locking assembly. The other end of each connecting assembly passes through the positioning flange and the sealing assembly. This utility model, with the cooperation of the sealing assembly, allows workers to quickly and effectively separate the input and output ends of the valve body at any time, ensuring connection safety. Furthermore, the cooperation of the positioning flange and sealing assembly facilitates the installation of the valve body in environments where the input and output ends of the pipeline are at different distances, effectively improving installation efficiency and applicability.
