Description

Technical Field

[0001] The utility model relates to the technical field of pan / tilt motors, in particular to a pan / tilt motor for installing a radar component. Background Art

[0002] When motors are used in the gimbal field, the PCB board is usually fixed directly to the gimbal motor. This helps to reduce the overall size and reduce the number of assembly steps. However, when it rains, although existing gimbal motors are designed with waterproof casings, water can easily seep into the gimbal motor through the gaps in the casing, causing the PCB board inside the gimbal motor to short-circuit due to water, and it is directly scrapped.

[0003] The radar assembly in the prior art is generally integrated into the pan / tilt motor through a bracket, see Figure 1 The existing gimbal motor 100 is connected to the gimbal motor adapter 200. A bracket 300 is installed at the end of the gimbal motor adapter 200 away from the gimbal motor 100. A ground-following radar 400 is installed at the bottom of the bracket 300, and an obstacle avoidance radar 500 is installed on the back. Although this installation structure has a high degree of integration, the center of gravity of the radar component and the overall structure of the bracket does not coincide with the axis of the gimbal motor. As a result, the gimbal motor consumes too much power when driving the overall structure of the radar component and the bracket to rotate through the gimbal motor adapter. In addition, this solution consumes more materials, is heavier, has higher costs, and has a relatively more complex structure.

[0035] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances. Example 1:

[0036] When motors are used in the gimbal field, the PCB board is usually fixed directly to the gimbal motor. This helps to reduce the overall size and reduce the number of assembly steps. However, when it rains, although existing gimbal motors are designed with waterproof casings, water can easily seep into the gimbal motor through the gaps in the casing, causing the PCB board inside the gimbal motor to short-circuit due to water, and it is directly scrapped.

[0037] In order to solve the above technical problems, this embodiment provides a pan-tilt motor for installing a radar component.

[0038] See also Figure 3-6 The pan-tilt motor 1 includes a stator assembly 2 and a rotor assembly 3. The rotor assembly 3 is engaged with the stator assembly 2 and can rotate relative to the stator assembly 2.

[0039] A back cover 4 is fixedly connected to one end of the stator assembly 2 away from the rotor assembly 3. An installation cavity is formed between the back cover 4 and the stator assembly 2. A PCB board 5 is installed in the installation cavity. A sealing cover 6 is provided between the PCB board 5 and the stator assembly 2. A glue filling area 7 for glue filling is provided between the PCB board 5 and the sealing cover 6.

[0040] Specifically, four studs 13 are distributed on the stator assembly 2 , and an installation space for installing the sealing cover 6 is formed between the four studs 13 . Four through grooves for engaging with the four studs 13 are opened on the side wall of the sealing cover 6 .

[0041] In this embodiment, four through holes are formed on the PCB board 5 for the four studs 13 to pass through. Two symmetrical support blocks 14 are installed on the stator assembly 2. The two support blocks 14 are respectively formed with a first threaded hole 15. The PCB board 5 is formed with two first through holes 16 corresponding to the two first threaded holes 15. Bolts 17 are respectively passed through the two first through holes 16 and the two first threaded holes 15 to fix the PCB board 5 on the stator assembly 2.

Bolts 17 are respectively passed through the two second through holes 21 and the two second threaded holes 20 to fix the back cover 4 and the stator assembly 2 together.

[0044] Specifically, a glue filling area 7 is set between the PCB board 5 and the sealing cover 6 for glue filling to generate a sealing glue layer that can provide waterproof protection for the PCB board 5, thereby achieving effective waterproofing of the pan-tilt motor 1 and preventing rainwater from penetrating into the interior of the pan-tilt motor 1, which would cause the PCB board 5 inside the pan-tilt motor 1 to be scrapped.

A ground-following radar 400 is installed at the bottom of the bracket 300, and an obstacle avoidance radar 500 is installed on the back. Although this installation structure has a high degree of integration, the center of gravity of the radar component and the overall structure of the bracket does not coincide with the axis of the gimbal motor.
