    • An automotive radar device and an antenna cover are disclosed. The automotive radar device includes a base, an antenna disposed on the base, and the antenna cover. The antenna cover includes a main portion and an engagement portion connected to the circumference of the main portion. The engagement portion can be engaged to the base such that the main portion covers the antenna. Therein, a thickness of the main portion along a radiation direction of the antenna is equal to half-wavelength corresponding to a center operation frequency of the antenna under a dielectric constant of the main portion. Thereby, energy radiated from the antenna can mostly pass through the main portion without excessive signal attenuation, which solves the insufficient signal intensity due to a protection cover in the prior art. Further, the main portion can be made of flexible and weather resistant material to improve its physical and chemical properties.
    • 公开了一种汽车雷达装置和天线罩。 汽车雷达装置包括基座,设置在基座上的天线和天线盖。 天线罩包括主体部分和与主体部分的圆周连接的接合部分。 接合部分可以接合到基座,使得主要部分覆盖天线。 其中,沿着天线的辐射方向的主要部分的厚度等于在主要部分的介电常数下对应于天线的中心操作频率的半波长。 因此,从天线辐射的能量可以大部分通过主要部分而没有过多的信号衰减,这解决了现有技术中由于保护罩引起的信号强度不足。 此外,主要部分可以由柔性和耐候性材料制成,以改善其物理和化学性质。

    • A vibrating crawl toy includes a housing. The housing includes a vibration motor therein. The vibration motor is located at a front end or a rear end of the housing. The housing further includes at least two rows of legs at a bottom thereof. The housing includes the vibration motor which is located at the front end or the rear end of the housing and the legs which are located at the bottom of the housing and used to walk. The vibration of the vibration motor brings the housing to sway and the housing brings the legs to advance on a table or on the ground, imitating walking of an animal. In particular, the present invention imitates an insect to crawl, enhancing amusement and fun.
    • 振动式爬行玩具包括壳体。 壳体包括振动电机。 振动马达位于外壳的前端或后端。 壳体还包括在其底部的至少两排腿。 壳体包括位于壳体的前端或后端的振动马达和位于壳体底部并用于行走的腿。 振动电机的振动使壳体摇摆,并且外壳使腿部在桌子上或地面上前进,模仿动物的行走。 特别地,本发明模仿昆虫爬行,增强娱乐和乐趣。
