Description

Technical Field

[0001] This utility model relates to a collapsing device, specifically an electric collapsing device for antennas. Background Technology

[0002] Antennas, as an essential component in communication, not only transmit and receive signals but also amplify them. Antennas are typically mounted on top of equipment, and manually raising and lowering them presents challenges such as high risk, poor operability, low efficiency, and limited environmental constraints. This is especially true for vehicle-mounted antennas, as the driving environment demands different antenna setups. Electric elevation devices allow communication vehicles to automatically lower and raise their antennas according to control commands, even when stationary or navigating obstacles like culverts, forests, and overpasses, eliminating the need for manual antenna installation in older communication vehicles. Utility Model Content

[0003] In view of the above situation, the purpose of this utility model is to provide an electric antenna tilting device, which adopts a combination of gear transmission, linear motion and cam mechanism to realize the stable raising and lowering of communication antenna.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electric antenna tilting device is provided, the structure of which includes: a front panel, a housing, a permanent magnet DC geared motor, a gear pair, a positioning device, a clutch device, an indexing device, a limit switch, a locking device, a vent valve, and a controller; the housing plays an important role in supporting and fixing the shaft components, ensuring the shaft's operational accuracy, good lubrication, and reliable sealing; the permanent magnet DC geared motor provides the electric transmission power source; the gear pair realizes the transmission reduction ratio; the positioning device, composed of an electromagnet, a guide sleeve, and a pin, is responsible for positioning the communication antenna; the clutch device, composed of a spring, a sliding shaft, a sliding bearing, and a handle, works with the limit switch to cut off and engage the power and transmission system; the indexing device, composed of a cam mechanism, a disc spring, and a handle, works with the limit switch to control the on / off action of the electromagnet; the locking device, composed of a fixed sleeve and a movable sleeve, secures the communication antenna to the output shaft and is responsible for the antenna's rotation, and is located on the front panel.

[0005] The positioning device has an electromagnet connected to a pin, a return spring passing through the pin, and a guide sleeve fixed on the circumferential surface of the pin and coaxial with the pin.

[0006] The clutch mechanism has a handle that passes through a sliding bearing seat, with a spring separating the two.

[0007] The indexing device has a handle that passes through a sliding bearing seat, with a disc spring separating the two. The indexing handle is installed on the right side wall of the housing.

[0008] The locking device consists of a fixed sleeve and a movable sleeve connected by fasteners.

[0009] The electric tilting device has a locking sleeve connected to the front panel; the large gear is connected to the output shaft by a positioning pin and to the shift fork block by fasteners; the large support plate is connected to the front panel via the left and right blocks; the small support plate is connected to the right block and the large support plate by fasteners; the upper and lower limit switches are mounted on the large support plate; the electromagnet is mounted on the small support plate and connected by a bracket; the electromagnet pin passes through the large gear to fix the large gear; the permanent magnet DC geared motor is mounted on the large support plate; the sliding bearing seat of the clutch device is connected to the front panel; and the sliding bearing seat of the indexing device is connected to the right side wall of the housing.

[0010] The electric tilting device is also equipped with a controller, which is generally located in the operating room. Its circuit connection is as follows: the controller is connected to the DC geared motor, limit switch, indicator light, and electromagnet respectively; the communication antenna feeds back information to the controller, and then the controller controls the DC geared motor to stop working.

[0011] When the controller issues a raise command, the retraction limit switch activates, the electromagnet actuates, and the pin moves linearly, disengaging from the large gear positioning hole. The lower limit switch then activates, and the DC geared motor starts operating. The "Lowered to Position" indicator light goes out. The small gear rotates, which in turn rotates the large gear, causing the output shaft to rotate and the locking device to rotate. The communication antenna rises. When it reaches a vertical position, the upper limit switch activates, the motor stops operating, and information is simultaneously fed back to the controller. The controller's "Lowered to Position" indicator light illuminates, the electromagnet is de-energized, and the pin resets, inserting into the large gear positioning hole. When the controller issues a lower command, the retraction limit switch activates, the electromagnet actuates, and the pin moves linearly, disengaging from the large gear positioning hole. The upper limit switch activates, and the DC geared motor starts operating. The "Lowered to Position" indicator light goes out, and the small gear rotates, which in turn rotates the large gear, causing the output shaft to rotate and the locking device to rotate. The communication antenna descends. When it reaches a horizontal position, the lower limit switch activates, the motor stops operating, and information is simultaneously fed back to the controller. The controller's "Lowered to Position" indicator light illuminates, the electromagnet is de-energized, and the pin resets, inserting into the large gear positioning hole.

[0012] In case of power failure, activate the manual function. Assuming the antenna is in a vertical position, rotate the indexing device handle on the right side wall to the "manual" position. The electromagnet pin will disengage from the large gear positioning hole. Rotate the clutch device handle on the front panel to the "manual" position. The pinion will disengage from the large gear. Hold the communication antenna and manually rotate it to a horizontal position. Rotate the indexing device handle on the right side wall to the "automatic" position. The electromagnet pin will insert into the large gear hole, positioning the large gear and fixing the antenna in a horizontal position.

[0013] The advantages of this utility model are: high positioning accuracy, high efficiency, user-friendly control, simplified structure, small size, light weight, high transmission efficiency, economical operation, wide range of transmitted power and speed, strong maintainability, and low production cost.
