Embodiment Construction

[0022] The technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0023] Such as figure 1 and figure 2 The shock-absorbing pad in the shown GNSS receiver is composed of a rigid bracket 1 and a soft rubber 2 wrapped outside the rigid bracket. Among them, the rigid support 1 is a cylindrical I-shaped, which is a cylindrical I-shaped rigid metal support, which mainly plays the role of support and fixation. The center of the cylinder is in the shape of a hole 3, and the screw 4 for fixing it to the housing passes through. The soft rubber 2 is wrapped on the rigid bracket, and the thickness of the wrapped rubber can determine the anti-seismic effect. For modules with different volumes, sizes, and weights, the thickness of the soft rubber may be different. Generally, the best choice for this thickness will be made in a targeted manner. When the shock-absorbing structure is finished, it can be clamped on the matchin...

Abstract

The invention relates to a shock-absorbing clamp cushion in a receiver of a GNSS (Global Navigation Satellite System). The shock-absorbing clamp cushion comprises a hard support and a flexible component wrapping the hard support, wherein a through hole for a screw to be arranged therein in a penetrating manner is formed in the hard support, the hard support is a cylindrical and I-type metallic support, and a through hole for a screw to be arranged in a penetrating manner is formed in the cylindrical center of the metallic support. The shock-absorbing clamp cushion enables a core module and a casing to form stable and flexible connection, enables an instrument to have stronger crash resisting and shock resisting capabilities, and in the GNSS receiver, the shock-absorbing clamp cushion is used for playing a shock-absorbing and protecting effect; quantity can be adjusted to be suitable according to size and weight of the core component so as to play an excellent effect to products; through the matching of modularized core component and shock-absorbing structural piece, the working efficiency is improved to a certain extent.

Description

technical field [0001] The invention relates to a shock-absorbing device for GNSS receiver products, in particular to a shock-absorbing pad that can achieve a good shock-absorbing effect in the anti-seismic and anti-drop test of the GNSS receiver. Background technique [0002] The full name of GNSS is Global Navigation Satellite System (Global Navigation Satellite System), which refers to all satellite navigation systems, including global, regional and enhanced, such as GPS in the United States, Glonass in Russia, Galileo in Europe, China's Beidou satellite navigation system, and related augmentation systems, such as WAAS (Wide Area Augmentation System) in the United States, EGNOS (European Geostationary Navigation Overlay System) in Europe, and MSAS (Multifunctional Transport Satellite Augmentation System) in Japan, etc., are also covered in and other satellite navigation systems to be built in the future. The international GNSS system is a multi-system, multi-level, multi...
