[0031] like Figure 1-Figure 5 As shown, the principle of the anti-torque attenuation stable limiter reinforcement plate provided in this embodiment is as follows: when the vehicle door is opened at a large angle, the limiter rod 5 will drive the baffle 51 to move toward the limiter box 3.

The buffered force is transmitted to the limiter box 3 through the buffer bottom plate 41, and then transmitted to the reinforced fixing plate 1 through the limiter box 3. Under the reinforcement of the connecting convex plate 16, the first reinforcing convex plate 17 and the second reinforcing convex plate 18, the reinforced fixing plate 1 dissipates the force transmitted from the limiter box 3, reduces the reaction force of the reinforced fixing plate 1 on the limiter box 3, reduces the impact and vibration of the limiter box 3 by external forces, increases the stability of the limiter box 3, and extends the service life of the vehicle door limiter.
