[0026] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0027] See also Figure 1 and Figure 2 . Figure 1 1 is a front view of a monitoring system according to an embodiment of the present application disposed on a fixing member 10 . Figure 2 yes Figure 1 Schematic diagram of the three-dimensional structure of the monitoring system shown.

[0028] In some embodiments, the monitoring system includes a base 20, a monitoring device 30, a connecting assembly 40, and a driving member 50. The monitoring device 30 is rotatably disposed on the base 20 around a first axis L1, and is used to obtain predetermined information of a target object 60. The target object 60 and the monitoring device 30 are arranged relative to each other along a predetermined direction. The connecting assembly 40 is rotatably connected to the base 20 around a second axis L2, and is rotatably connected to the monitoring device 30 around a third axis L3, and any two of the first axis L1, the second axis L2, and the third axis L3 are arranged in parallel and spaced apart. The dimension of the connecting assembly 40 along the spacing direction between the second axis L2 and the third axis L3 is adjustable, so that the monitoring device 30 rotates around the first axis L1, thereby making the orientation of the monitoring device 30 adjustable. The driving member 50 is used to drive the connecting assembly 40 to adjust the dimension along the spacing direction between the second axis L2 and the third axis L3.

[0029] In one application scenario, the monitoring system is used to monitor the vehicle status on the highway. In this application scenario, the predetermined direction is the extension direction of the road. The target object 60 is a vehicle traveling on the road. The monitoring device 30 is a radar video all-in-one machine, which is used to obtain the position information and image information of the target object 60. The radar video all-in-one machine is an intelligent sensor designed for vehicle-road collaboration. It is a traffic sensor that integrates a camera, a millimeter-wave radar, and a high-performance processor. The radar-vision fusion simultaneously connects the original video stream and the radar data stream to the embedded processor in the all-in-one machine. The original video stream is directly extracted in the built-in embedded processor, and then the video target is projected into the radar coordinate system through the built-in coordinate mapping system. Finally, the video target and the radar target are fused and tracked to achieve real-time vectorization and tracking of the global target.

[0030] In another application scenario, the monitoring system is used for monitoring goods in a shopping mall. In this application scenario, the target object 60 is a commodity on a shelf. The monitoring device 30 is a camera. The camera is set facing the commodity to obtain image information of the commodity.

[0031] The base 20 is used to be installed on the fixing member 10, and the fixing member 10 is usually located at a high place so that the monitoring device 30 can obtain a wider field of view. For example, the fixing member 10 is a gantry that is arranged across the road.

[0032] In some embodiments, the base 20 is detachably mounted on the fixing member 10 to facilitate replacement or maintenance of the monitoring device 30. The specific structure of the base 20 is not limited.

[0033] In some embodiments, the first axis L1 is a horizontal line, whereby the monitoring device 30 can adjust the pitch angle. In other embodiments, the first axis L1 is a vertical line, whereby the monitoring device 30 can swing left and right. In other embodiments, the first axis L1 is neither a horizontal line nor a vertical line. The first axis L1 is determined by the angle to be adjusted by the monitoring device 30.

[0034] The base 20, the monitoring device 30, and the connecting assembly 40 are generally arranged to form a three-link mechanism, and the overall structure is more stable. When the driving member 50 drives the connecting assembly 40 to adjust the size along the spacing direction of the second axis L2 and the third axis L3, the monitoring device 30 can be rotated around the first axis L1, so that the direction of the monitoring device 30 can be adjusted.

[0035] In some embodiments, the connection assembly 40 includes a first connection member 410, a transmission member 420, and a second connection member 430. The transmission member 420 is rotatably disposed on the first connection member 410 around the fourth axis L4. The second connection member 430 is screw-driven with the transmission member 420 so that the rotational motion of the transmission member 420 around the fourth axis L4 is converted into the linear motion of the second connection member 430 along the fourth axis L4. Among them, one of the first connection member 410 and the second connection member 430 is rotationally connected to the base 20 around the second axis L2, and the other of the first connection member 410 and the second connection member 430 is rotationally connected to the monitoring device 30 around the third axis L3, and the fourth axis L4 is perpendicular to the second axis L2 and the third axis L3, respectively, and the driving member 50 is used to drive the transmission member 420 to rotate around the fourth axis L4.

[0036] Specifically, in Figure 2 In the illustrated embodiment, the fourth axis L4 intersects the second axis L2 and the third axis L3, respectively. In other embodiments, the fourth axis L4 may also be spaced apart from the second axis L2 and the third axis L3, respectively.

[0037] Specifically, in Figure 2 In the illustrated embodiment, the first connecting member 410 is rotatably connected to the base 20 around the second axis L2, and the second connecting member 430 is rotatably connected to the monitoring device 30 around the third axis L3. In other embodiments, the arrangement positions of the first connecting member 410 and the second connecting member 430 may also be reversed, that is, the second connecting member 430 is rotatably connected to the base 20 around the second axis L2, and the first connecting member 410 is rotatably connected to the monitoring device 30 around the third axis L3.

[0038] Specifically, in Figure 2 In the illustrated embodiment, the outer surface of the transmission member 420 has a transmission matching portion (not shown) extending in a spiral around the fourth axis L4, and the second connecting member 430 is sleeved outside the transmission member 420, and is in spiral transmission cooperation with the transmission member 420 through the transmission matching portion. In other embodiments, the second connecting member 430 may also have a transmission matching portion extending in a spiral around the fourth axis L4, and the transmission member 420 is sleeved outside the second connecting member 430, and is in spiral transmission cooperation with the second connecting member 430 through the transmission matching portion.

[0039] During the rotation of the transmission member 420, the transmission member 420 drives the first connecting member 410 and the second connecting member 430 to move relative to each other along the fourth axis L4 to increase or decrease the spacing between the first connecting member 410 and the second connecting member 430 along the direction of the fourth axis L4, thereby realizing that the size of the connecting component 40 along the direction of the fourth axis L4 (the spacing direction between the second axis L2 and the third axis L3) is adjustable.

[0040] In this embodiment, when the monitoring device 30 is subjected to an external force, the external force causes the first connecting member 410 and the second connecting member 430 to have a tendency to move relative to each other along the fourth axis L4. Since a spiral transmission matching structure is adopted between the second connecting member 430 and the transmission member 420, the spiral transmission matching structure has a certain degree of self-locking function to prevent the first connecting member 410 and the second connecting member 430 from having relative movement along the fourth axis L4. Therefore, this embodiment can further improve the position stability of the monitoring device 30.

[0041] Please also read Figure 3 . Figure 3 yes Figure 1 3D exploded view of the monitoring system shown.

[0042] In some embodiments, the monitoring system further includes a mounting member 71 and a fastener 72 ( Figure 3 The fastener 72 detachably connects the mounting member 71 to the monitoring device 30. The fastener 72 is, for example, a bolt. The monitoring device 30 has a first through hole 301 extending along the third axis L3. The fastener 72 has a second through hole 711 extending along the third axis L3. A portion of the second connecting member 430 is inserted in the first through hole 301, and another portion is inserted in the second through hole. The second connecting member 430 is rotatably connected to the monitoring device 30 around the first axis L1. Since the mounting member 71 is detachable, it is easier to rotatably connect the second connecting member 430 to the monitoring device 30.

[0043] In some embodiments, the monitoring device 30 is rotatably connected to the base 20 around the first axis L1 via the first pin 73. The first connector 410 is rotatably connected to the base 20 around the second axis L2 via the second pin 74.

[0044] The specific structure of the above-mentioned rotation connection is not limited thereto, and other reasonable connection methods can be adopted.

[0045] In some embodiments, the connection assembly 40 further includes a limit member 440. The limit member 440 is disposed on the transmission member 420 and is used to abut against the second connection member 430 along the fourth axis L4, thereby limiting the limit position of the second connection member 430 moving relative to the transmission member 420 along the fourth axis L4, and further limiting the limit position of the monitoring device 30 rotating around the first axis L1.

[0046] Specifically, Figure 2In the illustrated embodiment, there are two limit members 440, and the two limit members 440 are spaced apart on opposite sides of the second connecting member 430 along the fourth axis L4 direction. The second connecting member 430 moves relative to the transmission member 420 within the range defined by the two limit members 440. When the second connecting member 430 abuts against one limit member 440, the second connecting member 430 moves to the first limit position relative to the transmission member 420, and at the same time, the monitoring device 30 rotates to the first limit angle relative to the base 20 around the first axis L1. When the second connecting member 430 abuts against the other limit member 440, the second connecting member 430 moves to the second limit position relative to the transmission member 420, and at the same time, the monitoring device 30 rotates to the second limit angle relative to the base 20 around the first axis L1. Therefore, the second connecting member 430 moves between the first limit position and the second limit position relative to the transmission member 420, and the monitoring device 30 rotates between the first limit angle and the second limit angle relative to the base 20 around the first axis L1.

[0047] In this embodiment, by providing the limiting member 440 , the extreme position of the rotation of the monitoring device 30 around the first axis L1 can be limited.

[0048] In some embodiments, the monitoring system further comprises a reducer (not visible in the figure). The driving member 50 is a motor, and the output shaft of the motor is mechanically coupled to the transmission member 420 through the reducer.

[0049] exist Figure 2 In the illustrated embodiment, the reducer is built into the first connecting member 410. The motor is fixedly disposed on the first connecting member 410. The reducer can reduce the rotation speed of the transmission member 420 and increase the rotation torque of the transmission member 420. The reducer can be an existing product, which will not be described in detail here.

[0050] The above-mentioned embodiments provide specific ways in which the size of the connecting component 40 is adjustable and the driving member 50 drives the connecting component 40 to adjust the size, but the present application is not limited thereto. Another example is given below.

[0051] See also Figure 4 . Figure 4 It is a cross-sectional schematic diagram of a connecting component 40 and a driving component 50 in a monitoring system according to an embodiment of the present application.

[0052] In some embodiments, the connecting assembly 40 includes a first connecting member 410 and a second connecting member 430. The first connecting member 410 is rotatably connected to the base 20 around the second axis L2. The second connecting member 430 is rotatably connected to the monitoring device 30 around the third axis L3. The first connecting member 410 and the second connecting member are slidably matched along the spacing direction of the first axis L1 and the second axis L2. Specifically, the first connecting member 410 and the second connecting member 430 can move relative to each other along the F direction. The driving member 50 is a linear motor. The body of the linear motor is fixedly connected to the second connecting member 430, and the driving end of the linear motor is connected to the first connecting member 410. The driving end can reciprocate relative to the body along the F direction, thereby driving the first connecting member 410 and the second connecting member 430 to move relative to each other along the F direction.

[0053] See also Figure 5 . Figure 5 It is a schematic diagram of the relative position relationship between the reference plane S and the first axis L1, the second axis L2 and the third axis L3 in the monitoring system of one embodiment of the present application.

[0054] In some embodiments, the monitoring system has a reference plane S, the reference plane S is perpendicular to the first axis L1, the first axis L1 and the reference plane S have a first intersection Q1, the second axis L2 and the reference plane S have a second intersection Q2, the third axis L3 and the reference plane S have a third intersection Q3, the first intersection Q1 and the third intersection Q3 have a first line L5, the second intersection Q2 and the third intersection Q3 have a second line L6, and the angle A between the first line L5 and the second line L6 is 80° to 100°. Further, the angle A between the first line L5 and the second line L6 is 90°.

[0055] By adopting the angle A mentioned above, the driving member 50 can drive the monitoring device 30 to rotate around the first axis L1 with a relatively small force.

[0056] In summary, the monitoring system provided in the embodiment of the present application can adjust the monitoring direction of the monitoring device 30 and can improve the stability of the monitoring device 30.

[0057] The introduction provided in the above steps is only used to help understand the method, structure and core idea of ​​the present application.
