To millimeter level radar wave sensor, its position is arranged in the lower grid region of vehicle usually, two supports are stretched out in the lower part of guaranteeing the crossbeam in front promptly, with millimeter level radar wave sensor snap-on the support, but this sensor arrangement scheme can lead to millimeter level radar wave sensor to damage in the collision, this is because after the pendulum has strikeed lower grid and sensor apron, can continue to strikeing millimeter level radar wave sensor, and because millimeter level radar wave sensor firmly fixes on the crossbeam support, therefore, can't carry out the energy-absorbing buffering, finally lead to millimeter level radar wave sensor to damage. The millimeter-scale radar wave sensor is extremely expensive in manufacturing cost, and the price for replacing a new millimeter-scale radar wave sensor is more than thousand yuan, so that the important significance for reducing the cost is achieved by protecting the sensor from being damaged during low-speed collision.
In addition, with the stricter requirements of future C-NCAP collision regulations and China insurance automobile safety indexes, if the radar wave sensors with the functions of adaptive cruise, emergency brake and the like are easily damaged in collision, the requirements of collision tests or 5-star collision can not be met.
While sensors can be placed in other locations to avoid the problem of vulnerability, other new problems arise, such as: if the radar wave sensor is placed near the upper grid car logo, in order to improve the radar wave penetrability, the indium plating process is needed to be adopted for the metal characters of the car logo, which inevitably causes the increase of the production cost; if the radar wave sensor is placed in the bumper skin area, due to the penetrability of radar waves, thickness calibration and experiments need to be carried out on bumper skins with different color numbers respectively, which is very inconvenient and easily causes the increase of production cost; if the radar wave sensor is directly fixed on the lower grating, vibration is generated due to wind resistance when the vehicle runs at a high speed, so that the function of the sensor is unstable, and once the vehicle collides, the sensor is directly impacted, so that the sensor is damaged.
Based on this, it is desirable to obtain a sensor protection device, which can be used to protect a sensor, especially a radar wave sensor, from being damaged by collision, so that the utilization rate of the sensor can be greatly improved, and the production cost and the test cost can be reduced.

When the pendulum bob 5 is slightly collided or driven at a high speed during the collision test, the lower grid 6 is moved backward by the external force F, but it does not contact the housing of the sensor 2, thereby not affecting the function of the sensor, and thus the detection area of the sensor 2 is not changed.
When the pendulum bob 5 moves forward to generate stronger collision, the external force F can firstly act on the housing cover plate 13, and then the second distance d2 is formed between the housing cover plate 13 and the sensor 2, so that the external force F applied to the housing cover plate 13 can be transmitted to the metal bracket 11 through the protective housing 12, and the metal bracket 11 deforms to absorb the impact force, thereby protecting the sensor 2 from falling or being damaged in the collision process, greatly reducing the risk of damage, and reducing the cost.
