Description

Technical Field

[0001] The invention relates to the technical field of vehicle roof antenna installation, and in particular to a vehicle roof bow-shaped antenna lodging device and an assembly method. Background Art

[0002] In the fields of communications and broadcasting, roof bow antennas are widely used to transmit signals between vehicles and the outside world. However, existing roof bow antennas are usually fixedly installed on the roof. When the vehicle passes through some height-restricted areas, such as low bridges, underground parking lots, etc., it is easy to be damaged by collision due to the excessive height of the antenna, which will not only cause the antenna to fail to work properly, but may also cause damage to the vehicle and surrounding facilities, increase maintenance costs and potential safety risks. Moreover, under some special working conditions, such as when the vehicle needs to travel at high speeds or off-road, a higher antenna will also increase wind resistance and affect the stability and fuel economy of the vehicle. In addition, some of the current adjustable antenna devices have complex structures, inconvenient operation, and low reliability, making it difficult to meet the diverse needs in actual use. Therefore, there is a need in the market for an antenna structure that can be lodged.

[0003] In the prior art, a Chinese patent with publication number CN203733923U discloses a device for lodging a cabin antenna. The cabin antenna is in a bow shape. The device for lodging the cabin antenna includes a reduction box arranged on the top wall of the cabin and a transmission shaft connected to the reduction box through a coupling on both sides of the reduction box. The transmission shaft is mounted on the top wall of the cabin through a bearing. The ends of the transmission shaft on both sides of the reduction box are respectively equipped with an antenna connector and an antenna seat flange for installing the bow antenna. A fixing clip is installed on the bow antenna, and an antenna support rod is installed on the transmission shaft. The antenna support rod is hingedly connected to the fixing clip on the bow antenna. When the cabin communication vehicle passes through obstacles such as culverts, woods, and overpasses, the flipping of the bow antenna can be controlled by manipulating the reduction box, so that the bow antenna is in a lodging state. After passing through obstacles such as culverts, woods, and overpasses, the bow antenna is in a vertical state, which can prevent the bow antenna on the top wall of the cabin from being damaged, and can improve the operating efficiency of the cabin communication vehicle.

[0004] The antenna retracting device provided by the above patent can retract the antenna when encountering obstacles such as height restrictions, trees or culverts to avoid damage to the antenna. However, the existing retracting mechanism of this structure does not have a structure to limit and fix the antenna after retracting, resulting in that when the vehicle is too bumpy, the retracted antenna will collide with the roof or the antenna support, thereby generating a lot of noise, and the collision will greatly reduce the life of the antenna, which is not conducive to the long-term use of the antenna.

The cooperation between the telescopic rod 81 and the clamp 82 is convenient for clamping on the antenna, thereby ensuring sufficient stability of the antenna.

[0061] like Figure 1 and Figure 4 As shown, it also includes a plurality of bearing seats 3, a transfer bearing 31 is provided in the middle of the bearing seat 3, and the transfer bearing 31 is interference-connected with the cross bar 2. This structure is convenient for the stability and use of the bearing seat 3. A support plate 32 is provided at the bottom of the bearing seat 3, and a bottom plate 33 is provided at the bottom end of the support plate 32. A plurality of bolt holes 34 are provided on the bottom plate 33. The support plate 32 cooperates with the bottom plate 33 to facilitate its stable support of the bearing seat 3, and the bolt holes 34 are convenient for fixing the position of the support seat.

[0062] Working principle: When in use, the entire inverting device is installed on the roof, and the dual-axis reducer 1 and the electric push rod 8 are energized; the dual-axis reducer 1 can rotate forward and reverse, and the bow antenna 5 can be rotated to a vertical state by the forward rotation of the dual-axis reducer 1 when working; when the vehicle passes through a height-restricted area or a forest, the bow antenna 5 can be inverted by reversing the dual-axis reducer 1, and the bow antenna 5 will be engaged with the inner side of the V-shaped opening of the antenna support 71 after being inverted. When the bow antenna 5 is engaged with the V-shaped opening of the antenna support 71, the electric push rod 8 will be triggered, and the electric push rod 8 will drive the clamping head 82 to engage with the antenna, thereby achieving the purpose of fixing the antenna; at the same time, when the vehicle is bumpy, the damping shock-absorbing seat 72 can reduce the vibration of the vehicle, thereby ensuring the stability of the bow antenna 5.

[0063] To sum up, compared with the prior art, the present application provides a limit assembly 7, on which an electric push rod 8 is installed. When the antenna falls onto the limit assembly 7, the electric push rod 8 extends, and the front end of the electric push rod 8 clamps the main bow antenna 5, ensuring that the bow antenna 5 is fixed inside the limit assembly 7, thereby avoiding collision between the bow antenna 5 and the antenna support 71, and ensuring that the bow antenna 5 is sufficiently stable. At the same time, a shock absorbing mechanism is provided at the bottom of the limit assembly 7, which can avoid damage to the antenna due to excessive vibration of the antenna.
