The invention discloses a satellite shell for protecting spacecraft time reference equipment and a protection assembly, which belong to the field of universe navigation equipment. The device comprisesa satellite shell plate body, a mounting outer box,and a connecting assembly, wherein the mounting outer box is fixedly arranged on the satellite shell plate body; a cavity is formed in the mountingouter box; a vibration reduction platform is arranged in the inner cavity; the vibration reduction platform is used for mounting a crystal oscillator; the connecting assembly is used for connecting the satellite shell plate bodies which are adjacently arranged. The satellite shell plate body is used for protecting a component provided with the crystal oscillator; the influence of external impact on the crystal oscillator is effectively avoided, and stable execution of the performance of the spacecraft is ensured; and a double-layer protection structure is designed, the supporting strength of key parts is guaranteed, low-frequency vibration reduction and impact resistance can be achieved, the advantages of being light in weight and high in rigidity are achieved, power consumption is reducedand the short-term frequency stability index of a product is improved on the basis that the performance index of the protected product is not affected, and high practical value is achieved.

    本发明公开了用于保护航天器时间基准设备的卫星壳体及保护组件,属于宇宙航行设备领域,本装置包括,卫星壳板体,安装外箱,安装外箱固设在卫星壳板体上,安装外箱内设腔室且内腔设有减振平台,减振平台用于安装晶振,连接组件,连接组件用于连接相邻布设的卫星壳板体,本发明采用卫星壳板体对安装有晶振的部件进行防护,有效避免外界冲击对晶振影响,保证航天器性能的稳定发挥,并且设计双层防护结构并保证关键部位支撑强度,能够实现低频减振、抗冲击,具有重量轻、刚度高的优点,对保护的产品性能指标无影响的基础上降低功耗并提高产品短期频率稳定度指标,具有较高的实用价值。
