Description

Technical Field

[0001] The utility model relates to an accessory device of a radar array antenna, in particular to an automatic locking and detection device used for the radar array antenna. Background Art

[0002] Radar antenna is a device used in radar to radiate and receive electromagnetic waves and determine its detection direction. It has the function of focusing electromagnetic waves into beams and emitting and receiving electromagnetic waves in a directionally direction. The important tactical performance of radar, such as detection distance, detection range, angle measurement (azimuth, elevation) accuracy, angle resolution and anti-interference capability, are all related to the performance of radar antenna.

[0003] There are many types of radar antennas. According to their structural form, there are mainly two categories: reflector antennas and array antennas. Radar array antennas are antenna systems composed of many identical single radar antennas arranged in a certain pattern. Their array forms include linear arrays and planar arrays.

[0004] During the transportation, docking and operation of radar array antennas, ensuring the stability of the antenna array (such as the array surface) is a prerequisite for the normal operation of the radar system, among which the locking of the antenna array is the most critical. When designing the locking device of the radar antenna array, it is necessary to meet the requirements of high reliability and monitorability of the locking, but the traditional locking device cannot take into account the performance of these two aspects well for the following reasons:

[0005] Most traditional locking devices for radar array antennas are driven by manual latches or hydraulics. Although this improves the simplified performance of the radar system, it is impossible to guarantee its reliability by relying solely on mechanical devices and hydraulic components. During driving, especially in complex and harsh working environments, vehicle vibrations can easily cause latches to fall off and cause failures. In addition, traditional manual latches and hydraulic component locking devices have the following problems: because there is no electronic feedback component, the staff cannot immediately know whether the latch is forgotten to be locked or whether the latch is locked in place, and cannot handle it in time, resulting in reduced system reliability. In addition, if there is an error in the lowering position of the radar array antenna, the latch lock may not be inserted into the keyhole, resulting in reduced system reliability and an important safety hazard of being unable to lock.

[0038] In order to illustrate the working principle of the automatic locking and detection device for radar array antenna described in the present invention, common application scenarios of the present invention are first introduced below.

[0039] like Figure 1 As shown, the radar array antenna vehicle-mounted device is a device that installs the radar array antenna 1 on the vehicle, which is convenient for transporting the radar array antenna to the required place to realize the radar signal receiving function. In the radar array antenna vehicle-mounted device, the radar array antenna 1 is installed on the antenna mounting bracket (not marked in the figure), the antenna mounting bracket is installed on the antenna prostrating device 3, the antenna prostrating device 3 is installed on the vehicle frame 2, and the antenna prostrating device 3 controls the antenna mounting bracket to prostrating through the prostrating support rod 4. After the radar array antenna 1 becomes horizontal, the end of the antenna mounting bracket is placed on the antenna support frame 5, and the antenna support frame 5 is installed on the vehicle frame 2. During transportation, the antenna mounting bracket must first be laid flat and locked in this state to ensure that the radar array antenna 1 is in a stable state during transportation to avoid damage; before use after transportation to the destination, the locked state must be released first, and then the radar array antenna 1 is opened through the antenna prostrating device 3 to make it vertical or oblique to realize the radar signal receiving function. Description: Antenna tumbling is a technical means, mainly used for vehicle-mounted antennas or other communication equipment. Its purpose is to prevent the antenna from being damaged when the vehicle passes through obstacles such as culverts, woods, and overpasses, thereby maintaining the continuity and efficiency of communication. This technology enables the antenna to be transformed from a vertical state to a horizontal state (tumbling), or from a horizontal state to a vertical state, through automatic or manual control, to adapt to different driving environments and protect the antenna from damage.

[0040] The lock hook 7 of the utility model is installed on the end of the antenna mounting bracket through the first connecting flange 9, and the lock arm 8, the guide member 14, the electric push rod 6 and other related components are installed on the antenna support frame 5 through the second connecting flange 16. The device can be used to realize the automatic locking and unlocking functions of the radar array antenna 1 and the detection function of the locking state. The specific principle is as follows:

[0041] If the locking function is required, the device is first in Figure 2 and Figure 3 In the unlocked state shown in the figure, at this time, the driving motor of the electric push rod 6 is started by the controller control (generally, the staff presses the lock button to give a lock command, and the controller automatically implements the relevant control functions after receiving the command), and drives the telescopic rod 15 to move downward (that is, in the direction away from the lock hook 7, the same below). During this process, the circular boss 26 first slides in the arc guide groove 27. Under the cooperation of the circular boss 26 and the arc guide groove 27, the movement trajectory of the lock arm 8 is downward and at the same time laterally approaches the lock hook 7. When the circular boss 26 moves to the lower side of the linear guide groove 25, the circular boss 26 moves to the lower side of the linear guide groove 25. When the end is reached, the lock shaft 11 in the upper part of the figure crosses the end of the lock hook 7 and is just located above the open lock slot; the telescopic rod 15 continues to move downward, and under the cooperation of the circular boss 26 and the linear guide groove 25, the lock shaft 11 in the upper part of the figure moves vertically downward until it enters the open lock slot of the lock hook 7 and is in close contact. At this time, the second magnetic induction switch 21 detects the signal of the magnetic ring on the telescopic rod 15 and transmits the signal to the controller. The controller controls the driving motor of the electric push rod 6 to stop running, so that the telescopic rod 15 stops moving. At this time, the device and the radar array antenna 1 are in a locked state, as shown in FIG. Figure 4 As shown, the locking function is completed and the staff understands the status through the controller.

[0042] On the contrary, if the unlocking function is required, the device is first in Figure 4 In the locked state shown in the figure, the driving motor of the electric push rod 6 is started by the controller to drive the telescopic rod 15 to move upward (i.e., in the direction close to the lock hook 7, the same below). During this process, the circular boss 26 first slides in the linear guide groove 25. Under the cooperation of the circular boss 26 and the linear guide groove 25, the upper lock shaft 11 in the figure moves vertically upward until there is a sufficient distance between the open lock groove of the lock hook 7. Then, the circular boss 26 starts to slide in the arc guide groove 27. Under the cooperation of the circular boss 26 and the arc guide groove 27, the circular boss 26 and the arc guide groove 27 are moved vertically upward. The movement trajectory of the lock arm 8 is upward and laterally away from the lock hook 7 until the lock shaft 11 in the upper part of the figure crosses the end of the lock hook 7 and moves away from the lock hook 7. When the circular boss 26 moves to the lower end of the arc-shaped guide groove 27, there is a sufficient safety distance between the upper lock shaft 11 in the figure and the lock hook 7. At this time, the first magnetic induction switch 19 detects the signal of the magnetic ring on the telescopic rod 15 and transmits the signal to the controller. The controller controls the driving motor of the electric push rod 6 to stop running, so that the telescopic rod 15 stops moving. At this time, the device and the radar array antenna 1 are in an unlocked state, as shown in FIG. Figure 2 and Figure 3 As shown, the unlocking function is completed, and the staff understands the status through the controller.

[0043] Figure 2 , Figure 3 and Figure 4 Also shown is a connecting shaft 23 for connecting the lower end of the electric push rod 6 with the electric push rod mounting seat 22. Figure 4 and Figure 5 Still showing the locking arm material and weight reduction groove 24 provided on the locking arm 8, Figure 6 Also shown are guide member material and weight reduction grooves 29 provided on the guide member 14, which are conventional adaptive structures.

[0044] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
