  • Publication number: 20190176746
    Abstract: The present invention discloses a lateral shock absorber disposed on a base of a child car safety seat. The lateral shock absorber includes a protective fender. An end of the protective fender is pivoted to the base, so that the protective fender is pivotally switchable between a folded state and an unfolded state relative to the base. The unfolded protective fender can collide with a car body during a side impact collision for transferring a side impact to the base and away from a child sitting in the child car safety seat. Therefore, it can effectively reduce a risk of injury or death of the child due to the side impact and provide enhanced protection for the child. Furthermore, the lateral shock absorber has advantages of simple structure and easy operation. Besides, the present invention further discloses a child car safety seat with the aforementioned lateral shock absorber.

  • Patent number: 10312036
    Abstract: A keyboard device includes plural key structures, a switch circuit board, an elastic cover and a seal element. The switch circuit board includes a hollow region. The elastic cover is disposed on the switch circuit board. The hollow region is covered by the elastic cover, so that a foreign liquid is prevented from entering the switch circuit board. The seal element is disposed on sidewalls of the switch circuit board. Consequently, a sealed region is formed between the switch circuit board and the elastic cover. When the inner gas within the switch circuit board is changed, the elastic cover is subjected to expansion or contraction. Consequently, the switch circuit board is not subjected to deformation in response to the volume change of the inner gas.
