[0002] Vehicle-mounted antenna is important mobile communication equipment, because it has high mobility, does not need infrastructure and can quickly change scene to different places to perform tasks, has been more and more applied to emergency communication, military communication and other various scenes in our country.

[0003] Generally, vehicle-mounted antenna with large height is often realized overturning action by using a set of overturning mechanism to meet the height requirement in working and height limit requirement in transportation state, so that antenna is in the state of lodging in transportation state, and antenna is erected and lifted to a certain height in working state.

[0004] Traditional overturning mechanism mostly uses telescopic two-force rod structure, commonly used such as electric push rod or hydraulic push rod etc.Form. Force support is arranged before and after antenna stand, and telescopic two-force rod structure is arranged on it, and the lodging and erecting action of antenna stand is realized by the telescopic push-pull of two-force rod structure. Within a certain scale, the structure is reasonable and reliable, but it is not suitable for large vehicle-mounted antenna. Large vehicle-mounted antenna is higher and heavier, and limited by the size of vehicle body, two-force rod can only be designed as "thick and strong", not "tall and big". In such design, the stress point of overturning mechanism for antenna stand is too low, which has the risk of low reliability. SUMMARY

[0005] Therefore, the utility model provides a kind of cable drive overturning movement's vehicle-mounted antenna, which abandons telescopic two-force rod structure in traditional form, and mainly uses new structure of winch and flexible steel cable to realize the overturning action of antenna.

[0016] Thirdly, when the vehicle-mounted antenna 2 is in the upright state, i.e. after the overturning movement is moved to the position, the winch mechanism 4 stops moving, and the limiting locking mechanism 10 starts the locking action, thereby locking the upright angle of the vehicle-mounted antenna.

[0017] In the process of the vehicle-mounted antenna from the working state to the storage state, the antenna vertical cylinder gradually adjusts from the upright posture to the prostrate posture, and the movement control process is opposite to the above process.
