Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted protective equipment, in particular to a shock-resistant decoder and a 360-degree panoramic navigator. Background Art

[0002] The function of the vehicle-mounted decoder is to convert digital signals into analog signals so that they can be output by devices such as speakers and displays. Since the vehicle needs to travel on the road, especially when the vehicle travels to a speed bump or a bumpy road section, the vehicle will produce a large bump vibration, which will cause the vehicle-mounted decoder to vibrate as well. This will cause the electronic components in the vehicle-mounted decoder to vibrate, affecting the service life of the vehicle-mounted decoder. For example, in the Chinese utility model patent application with application number 202020789910.3, a shock-absorbing spring is provided and the elastic force of the shock-absorbing spring is utilized to form a soft connection between the decoder and the splint. When vibration occurs, the vibration force applied to the decoder is reduced, thereby improving the shock resistance and extending the service life. However, it requires additional auxiliary structures to achieve shock absorption of the decoder, which greatly increases the structural complexity of the decoder. In addition, the shock-absorbing spring is arranged horizontally, so that its elasticity maintenance effect is poor. Under long-term use, it is easy to cause the shock absorption effect of the decoder to be reduced or fail, which is not conducive to maintaining the shock absorption effect of the decoder for a long time.
