Description

Technical Field

[0001] This application belongs to the field of electromagnetic wave signal azimuth control technology, specifically relating to an azimuth drive mechanism for a radar transceiver unit. Background Technology

[0002] The radar transceiver unit is the core component of a radar system, responsible for transmitting and receiving electromagnetic wave signals. By processing parameters such as echo delay and Doppler shift, it calculates information such as the target's range, velocity, and azimuth. The radar transceiver unit is controlled by an azimuth drive mechanism. Specifically, the azimuth drive mechanism is mounted on the radar's mounting surface, and the radar transceiver unit is fixed to the transmission components of the azimuth drive mechanism. When the azimuth drive mechanism is activated, the relevant drive components can change the orientation of the radar transceiver unit to lock onto the corresponding target element.

[0003] Existing radar transceiver units typically use an external power supply. However, the combination of such products with corresponding azimuth drive mechanisms has significant limitations. Specifically, due to the length and arrangement of the power cable, the azimuth drive mechanism can only drive the radar transceiver unit to rotate back and forth within a limited angular range. Once the set angle is exceeded, the power cable is prone to tangling, which not only affects the normal operation of the equipment but may also cause damage to the wiring.

[0004] This technical defect prevents the radar transceiver unit from achieving continuous rotation, severely restricting the equipment's working efficiency and operational flexibility, and making it difficult to meet the ever-increasing performance requirements of modern application scenarios for radar systems. Therefore, there is an urgent need in the existing technology for an azimuth drive mechanism that can drive the radar transceiver unit to rotate, as well as a radar assembly with this function. Utility Model Content

[0005] This application provides an azimuth drive mechanism for a radar transceiver unit, designed to drive the radar transceiver unit to rotate continuously to meet user needs.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] An azimuth drive mechanism for a radar transceiver unit is provided, comprising:

[0008] The housing is used to secure the radar to the installation area.

[0009] An adapter, disposed on the upper side of the housing, has a degree of freedom of rotation relative to the housing, and the adapter is used for fixing and electrically connecting the radar transceiver unit;

[0010] A rotary drive assembly, disposed inside the housing and connected to the adapter, is used to drive the adapter to rotate about its own central axis and to drive the radar transceiver unit to rotate; and

[0011] A conductive slip ring has its stator end fixedly disposed inside the housing and is used for electrical connection with an external power supply; the rotor end of the conductive slip ring is connected to the adapter and is used to transmit electrical energy to the adapter for use by the radar transceiver unit.

[0012] In one possible implementation, the adapter has a disc-shaped structure and is coaxially arranged with the conductive slip ring.

[0013] In one possible implementation, a bracket is provided on the upper side of the adapter, the bracket being used for embedding and fixing the radar transceiver unit;

[0014] An azimuth connector is provided on the outside of the bracket. The azimuth connector is electrically connected to the adapter to supply power to the azimuth connector. The azimuth connector is also used to electrically connect to the radar transceiver unit to transmit signals.

[0015] In one possible implementation, the adapter is provided with a sealing ring between the housings, the sealing ring being used to fill the gap between the adapter and the housing;

[0016] The upper end of the sealing ring is connected to the adapter, and the lower end of the sealing ring is connected to the outer shell through a mating structure.

[0017] In one possible implementation, the adapter has a plurality of through holes spaced apart circumferentially thereon; the sealing ring has a plurality of threaded grooves spaced apart circumferentially thereon, the plurality of threaded grooves being adapted to communicate with the plurality of through holes one by one.

[0018] Each of the through holes is fitted with a connecting bolt, and the connecting bolt is adapted to be threaded into the threaded groove to connect the adapter and the sealing ring.

[0019] In one possible implementation, the docking structure includes:

[0020] Multiple retaining rings arranged coaxially are disposed on the upper end face of the housing to form multiple coaxially arranged annular slots; and

[0021] Multiple interlocking rings are coaxially arranged on the lower end face of the sealing ring and are adapted to be inserted one-to-one into the multiple annular slots to restrict the movement of the sealing ring relative to the housing in its own radial direction.

[0022] In one possible implementation, the rotary drive assembly is a servo direct drive shaft system;

[0023] The stator end of the servo direct drive shaft system is fixedly disposed inside the housing, and the rotor end of the servo direct drive shaft system is connected to the adapter.

[0024] In one possible implementation, the adapter has a strip-shaped hole at the center of its bottom surface, and the rotor end of the conductive slip ring is embedded in the strip-shaped hole.

[0025] In one possible implementation, the housing has a bottom-opening structure, and a cover plate is detachably connected to the housing for closing its bottom opening.

[0026] In one possible implementation, the housing is provided with a power connector electrically connected to the conductive slip ring, and a network connector for transmitting signals.

[0027] In this embodiment, the housing is used to house and protect the internal rotary drive assembly and conductive slip ring. Based on this, the rotary drive assembly provides kinetic energy for the rotation of the adapter, thereby driving the rotation of the radar transceiver unit. In addition, the conductive slip ring ensures the supply of electrical energy to the adapter, thereby enabling the supply of electrical energy to the radar transceiver unit.

[0028] When the radar transceiver unit rotates, the adapter and the radar transceiver unit maintain an electrical connection, and the conductive slip ring and the adapter maintain an electrical connection.

Therefore, it can ensure the power supply of the radar transceiver unit while driving the radar transceiver unit to rotate continuously to meet user needs. Attached Figure Description

[0044] Please refer to the following: Figures 1 to 8 The azimuth drive mechanism for a radar transceiver unit provided in this application will now be described. The azimuth drive mechanism for a radar transceiver unit proposed in this application includes a housing 1, an adapter 2, a rotary drive assembly 3, and a conductive slip ring 4.

[0045] The outer casing 1 is used to fix it in the installation area of ​​the radar. Specifically, the outer casing 1 adopts an internally hollow cylindrical structure. The lower end of the structure has an outwardly protruding structure that extends radially outward. The outwardly protruding structure is provided with a through hole that can cooperate with the installation area. In actual installation, the outer casing 1 is aligned with the through hole and fixed by a matching locking member.

[0046] The adapter 2 is mounted on the upper side of the housing 1 and has a degree of freedom of rotation relative to the housing 1. Specifically, the adapter 2 can rotate about the central axis of the housing 1, thereby driving the radar transceiver unit 10 fixed on the adapter 2 to rotate synchronously. By adjusting the fixed position of the radar transceiver unit 10, the rotation axis of the radar transceiver unit 10 can be made collinear with its own central axis, so as to realize the rotation of the radar transceiver unit 10. At the same time, after adjusting the fixed position, the adapter 2 and the radar transceiver unit 10 are electrically connected to achieve the technical purpose of the adapter 2 supplying power to the radar transceiver unit 10.

[0047] The rotary drive assembly 3 is located inside the housing 1 and is connected to the adapter 2 for driving the adapter 2 to rotate around its own central axis and drive the radar transceiver unit 10 to rotate.

[0048] The conductive slip ring 4, also known as a rotary electrical interface, electric slip ring, or collector ring, is an electromechanical device used to transmit current, signals, or data between a fixed structure and a rotating component. In this embodiment, the conductive slip ring 4 has a stator and a rotor. The stator end of the conductive slip ring 4 is fixedly disposed inside the housing 1 and is used for electrical connection with an external power supply. In addition, the rotor end of the conductive slip ring 4 is connected to the adapter 2 and is used to transmit electrical energy to the adapter 2 for use by the radar transceiver unit 10.

[0049] In this embodiment, the outer shell 1 is used to house and protect the internal rotary drive assembly 3 and conductive slip ring 4. Based on this, the rotary drive assembly 3 provides kinetic energy for the rotation of the adapter 2, thereby driving the rotation of the radar transceiver unit 10. In addition, the conductive slip ring 4 ensures the supply of electrical energy to the adapter 2, thereby achieving the power supply to the radar transceiver unit 10.

[0050] When the radar transceiver unit 10 rotates, the adapter 2 and the radar transceiver unit 10 maintain an electrical connection, and the conductive slip ring 4 and the adapter 2 maintain an electrical connection. Therefore, this mechanism can ensure the power supply of the radar transceiver unit 10 under continuous rotation.

[0051] Compared with the prior art, the azimuth drive mechanism for the radar transceiver unit provided in this embodiment does not have an external power supply line directly connected to the radar transceiver unit 10. Therefore, while ensuring the power supply of the radar transceiver unit 10, it can also drive the radar transceiver unit 10 to rotate continuously to meet user needs.

[0052] In some embodiments, such as Figure 4 As shown, the adapter 2 adopts a disc-shaped structure to be fitted onto the upper side of the housing 1 and is coaxially arranged with the housing 1. The adapter 2 is coaxially arranged with the aforementioned conductive slip ring 4 to further ensure the stability of the electrical connection between the adapter 2 and the conductive slip ring 4 when the adapter 2 rotates.

[0053] In some embodiments, such as Figure 1 , Figure 2 and Figure 8 As shown, a bracket 21 is provided on the upper side of the adapter 2. The bracket 21 is used for embedding and fixing the radar transceiver unit 10.

[0054] An azimuth connector 211 is provided on the outside of the bracket 21. The azimuth connector 211 is electrically connected to the adapter 2 to supply power to the azimuth connector 211. The azimuth connector 211 is also used to electrically connect to the radar transceiver unit 10 to transmit digital signals.

[0055] In some embodiments, such as Figure 1 and Figure 4 As shown, the adapter 2 has a sealing ring 5 between the housing 1 and the housing 1, and the sealing ring 5 is used to fill the gap between the adapter 2 and the housing 1.

[0056] In actual use, the upper end of the sealing ring 5 is connected to the adapter 2, and the lower end of the sealing ring 5 is connected to the outer shell 1 through the mating structure 6.

[0057] In some embodiments, such as Figure 2 and Figure 3 As shown, the adapter 2 has a plurality of through holes 22 spaced apart along its circumference; the sealing ring 5 has a plurality of threaded grooves 51 spaced apart along its circumference, and the plurality of threaded grooves 51 are adapted to communicate with the plurality of through holes 22 one by one.

[0058] Each through hole 22 is fitted with a connecting bolt 23, which is adapted to be threaded into the threaded groove 51 to connect the adapter 2 and the sealing ring 5, thereby realizing a detachable connection between the adapter 2 and the sealing ring 5.

[0059] In some embodiments, such as Figure 7 As shown, the docking structure 6 includes multiple fixing rings 61 and multiple insertion rings 62.

[0060] Multiple retaining rings 61 have different inner diameters and are coaxially arranged; multiple retaining rings 61 are all arranged on the upper end face of the outer shell 1 to form multiple coaxially arranged annular slots.

[0061] Multiple insertion rings 62 have different inner diameters and are coaxially arranged; multiple insertion rings 62 are all arranged on the lower end face of the sealing ring 5 and are suitable for being inserted into multiple annular slots one by one to limit the movement of the sealing ring 5 relative to the outer shell 1 in its own radial direction.

[0062] In some embodiments, such as Figure 4 As shown, the rotary drive component 3 is a servo direct drive shaft system; this servo direct drive shaft system is a high-precision, high-efficiency rotary or linear motion control system that achieves zero backlash and high dynamic response motion control by directly coupling the servo motor to the load shaft (without intermediate transmission mechanisms such as gears or belts).

[0063] Specifically, the stator end of the servo direct drive shaft system is fixedly installed inside the housing 1, and the rotor end of the servo direct drive shaft system is connected to the adapter 2 to drive the rotation of the adapter 2.

[0064] In some embodiments, such as Figure 3 and Figure 4 As shown, the bottom surface of the adapter 2 has a strip-shaped hole 24 at the center, and the rotor end of the conductive slip ring 4 is embedded in the strip-shaped hole 24. In this embodiment, the adapter 2 is a waist-shaped groove opened on its bottom surface, and the rotor end of the conductive slip ring 4 is matched and embedded in the groove so that when the rotor end rotates, the adapter 2 rotates synchronously.

[0065] In some embodiments, such as Figure 7As shown, the outer casing 1 has an open bottom structure, and a cover plate 11 for closing its open bottom is detachably connected to the outer casing 1.

[0066] In actual use, after removing the outer casing 1 from the mounting surface, the cover plate 11 can be removed to repair, dismantle, and adjust other components inside the outer casing 1.

[0067] In some embodiments, such as Figure 1 As shown, the housing 1 is provided with a power connector 7 that is electrically connected to the conductive slip ring 4. In use, an external power cord is electrically connected to the power connector 7 to supply power to the conductive slip ring 4. The housing 1 is also provided with a network connector 8 for transmitting signals. The network connector 8 is electrically connected to the radar transceiver unit 10 to realize the transmission of digital signals.
