Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to an encoder driving mechanism and a monitoring device. Background Art

[0002] An encoder is a sensor used to detect and measure the position, speed, and angle of rotational or linear motion. The existing encoder driving mechanism arranges a ring magnet around the outer circle of the rotating shaft, and then fixes the encoder near the ring magnet for detection, which can significantly improve the accuracy of detecting the rotation angle. At present, the driving mechanism is gradually developing towards miniaturization, and the space near the rotating shaft is small, so the ring magnet cannot be arranged around the outer circle of the rotating shaft, and the rotation angle of the rotating shaft cannot be synchronized, resulting in the encoder being unable to detect.

[0025] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the implementation modes and with reference to the drawings

[0026] Please refer to Figure 1 , an encoder driving mechanism, comprising a driving motor, a conveyor belt, a rotating shaft, a timing belt, a ring magnet synchronous pulley and an encoder; the output shaft of the driving motor is connected to the input shaft of the rotating shaft through the conveyor belt; the input shaft of the rotating shaft is further connected to the ring magnet synchronous pulley through the timing belt; the encoder is arranged on one side of the ring magnet synchronous pulley for detecting the rotation angle of the ring magnet synchronous pulley

[0027] As can be seen from the above description, the beneficial effect of the present invention is that: by setting the timing belt and the ring magnet synchronous pulley, the rotation angle of the rotating shaft can be synchronized to the ring magnet synchronous pulley through the timing belt, so that the encoder can detect the rotation angle of the rotating shaft by detecting the rotation angle of the ring magnet synchronous pulley; at the same time, since the encoder is arranged on the ring magnet synchronous pulley, the encoder does not occupy the space around the rotating shaft, so that the measurement of the rotation angle of the rotating shaft can be realized even when the space around the rotating shaft is small

[0028] Furthermore, it further comprises a fixed plate; the driving motor, the conveyor belt, the rotating shaft, the timing belt, the ring magnet synchronous pulley and the encoder are all arranged on the fixed plate

[0029] As can be seen from the above description, by arranging the driving motor, the conveyor belt, the rotating shaft, the timing belt, the ring magnet synchronous pulley and the encoder on the fixed plate, that is, the overall integration of the mechanism is realized through the fixed plate, and the stability of the overall mechanism is improved

[0030] Furthermore, the rotating shaft and the ring magnet synchronous pulley are respectively arranged on opposite sides of the fixed plate; the input shaft of the rotating shaft penetrates the fixed plate, and a first rotating part and a second rotating part are respectively formed on both sides of the fixed plate; the first rotating part is connected to the conveyor belt; the second rotating part is connected to the timing belt

[0031] As can be seen from the above description, by separately arranging the rotating shaft and the annular magnet synchronous pulley on both sides of the fixing plate, the rotating shaft can be arranged outside the housing during assembly, thereby reducing the occupation of the internal space of the housing.

[0032] Furthermore, the driving motor is arranged on the side of the fixing plate where the annular magnet synchronous pulley is arranged; the output shaft of the driving motor penetrates through the fixing plate and is connected to the conveyor belt.

[0033] As can be seen from the above description, by arranging the driving motor and the annular magnet synchronous pulley on the same side of the fixing plate, both the driving motor and the annular magnet synchronous pulley are arranged inside the housing during assembly, which plays a protective role for the driving motor.

[0034] Furthermore, the driving motor and the annular magnet synchronous pulley are respectively arranged at both ends of one side of the fixing plate.

[0035] As can be seen from the above description, by arranging the driving motor and the annular magnet synchronous pulley at both ends of one side of the fixing plate, an avoidance space can be formed around the input shaft of the rotating shaft to meet the placement requirements of other mechanisms or modules.

[0036] Furthermore, the rotating shaft and the annular magnet synchronous pulley are both arranged on the same side of the fixing plate; the output end of the rotating shaft includes a third rotating part and a fourth rotating part, the third rotating part is connected to the conveyor belt, and the fourth rotating part is connected to the synchronous belt.

[0037] As can be seen from the above description, by arranging the rotating shaft and the annular magnet synchronous pulley on the same side of the fixing plate, the overall thickness of the mechanism is reduced compared to being separately arranged on both sides of the fixing plate, and it can be applied to the application scenarios with small volume on one side.

[0038] Furthermore, it further includes a fixing column; the fixing column is arranged around the edge of the annular magnet synchronous pulley; the encoder is mounted on the annular magnet synchronous pulley.

[0039] As can be seen from the above description, by arranging the fixing column, the encoder can be mounted on the annular magnet synchronous pulley, thereby effectively detecting the rotation angle.

[0040] Another embodiment of the present utility model provides a monitoring device, including a camera, a housing, and the above-mentioned encoder driving mechanism; the encoder driving mechanism is arranged inside the housing; the output end of the rotating shaft is arranged outside the housing and is connected to the camera.

[0041] As can be seen from the above description, by arranging the encoder driving mechanism inside the housing, the protection of the encoder driving mechanism is realized, and at the same time, the output end of the rotating shaft is connected to the camera to realize the rotation control of the camera, which is more beneficial for the camera to conduct monitoring.

[0042] Further, it further includes a rotation mechanism for controlling the rotation of the housing; the rotation mechanism is arranged in the avoidance space formed between the synchronous belt and the inner wall of the housing.

[0043] As can be seen from the above description, by setting the rotation mechanism, the rotation of the housing can be realized, and the rotation mechanism is arranged in the avoidance space formed between the synchronous belt and the inner wall of the housing, making the structure more compact and applicable to small-volume scenarios.

[0044] Further, the housing is a cuboid; the encoder driving mechanism is arranged on the side surface of the housing; the rotation mechanism is arranged on the top surface or the bottom surface of the housing.

[0045] As can be seen from the above description, by arranging the encoder driving mechanism and the rotation mechanism on the top surface and the side surface of the housing respectively, the encoder driving mechanism and the rotation mechanism do not interfere with each other, and respectively realize the control of the rotation of the camera and the control of the overall rotation of the device.

[0046] The encoder driving mechanism and the monitoring device provided by the present utility model can be applied to the scenarios of a pan-tilt or a monitoring device, which will be described below through specific embodiments:

And, the driving motor 1 and the ring magnet synchronous pulley 5 are respectively arranged at both ends on one side of the fixing plate 7. As Figure 1 and Figure 2As shown, the rotating shaft 3 and the conveyor belt 2 are arranged on the right side of the fixed plate 7, and the driving motor 1, the synchronous belt 4, the annular magnet synchronous pulley 5 and the encoder 6 are arranged on the left side of the fixed plate 7, and the driving motor 1, the rotating shaft 3 and the annular magnet synchronous pulley 5 are arranged on the same straight line. Among them, the encoder 6 is mounted on the annular magnet synchronous pulley 5 through the fixed column 8; as Figure 1 shown, the fixed column 8 is arranged around the edge of the annular magnet synchronous pulley 5, one end of the fixed column 8 is connected to the fixed plate 7, and the other end is connected to the encoder 6.

[0050] In another alternative embodiment, both the rotating shaft 3 and the annular magnet synchronous pulley 5 are arranged on the same side of the fixed plate 7; the output end of the rotating shaft 3 includes a third rotating part and a fourth rotating part, the third rotating part is connected to the conveyor belt 2, and the fourth rotating part is connected to the synchronous belt 4. For example, both the rotating shaft 3 and the annular magnet synchronous pulley 5 are arranged on the left side of the fixed plate 7. At the same time, the driving motor 1 can also be arranged on the left side of the fixed plate 7, that is, all components are arranged on the same side of the fixed plate 7.

[0051] The specific working principle of the above encoder driving mechanism is as follows:

[0052] The output shaft of the driving motor 1 is connected to the rotating shaft 3 through the conveyor belt 2, and is used to drive the rotating shaft 3 to rotate a certain angle; at the same time, the rotating shaft 3 is connected to the annular magnet synchronous pulley 5 through the synchronous belt 4, so as to synchronize the rotation angle of the rotating shaft 3 to the annular magnet synchronous pulley 5, and the rotation angle is detected by the encoder 6 arranged above the annular magnet synchronous pulley 5, so as to realize the angle detection of the rotating shaft 3.

[0053] Embodiment 2

[0054] Please refer to Figure 3 and Figure 4 , a monitoring device, including a camera 100, a housing 110 and the encoder driving mechanism 120 described in Embodiment 1; wherein, the encoder driving mechanism 120 is arranged in the housing 110; the output end of the rotating shaft 3 is arranged outside the housing 110 and is connected to the camera 100.

[0056] As Figure 4 shown, in this embodiment, the equipment is miniaturized while meeting the basic functions; after the rotating shaft 3 and the housing 110 are fixed, other structures need to surround the main shaft and be placed inside the housing 110 as much as possible; among them, since the space between the fixing plate 7 and the housing 110 is very narrow, the conveyor belt 2 and the synchronous belt 4 are arranged on both sides of the fixing plate 7, and a synchronous belt 4 with a relatively thin thickness is used to adapt to the layout of the small space around the rotating shaft 3, and the motor with a direct drive structure is changed to a belt drive, so that the rotation angle of the rotating shaft 3 can be synchronized to the annular magnet synchronous pulley 5 when the space around the rotating shaft 3 is small, and then it is convenient for the encoder 6 to detect. While meeting the detection accuracy of the rotation angle, a layout structure for a type of scenario is provided, greatly improving its scenario adaptability.
