Description

Technical Field

[0001] This utility model relates to the field of visual sensor technology, specifically a dynamic visual sensor module. Background Technology

[0002] A visual sensor is a device that can sense and process visual information. It can convert optical images into electrical or digital signals so that computers or other devices can analyze and process them. Dynamic vision is an important branch of computer vision, which mainly studies how to enable computers or other intelligent systems to understand and process visual information in dynamic scenes.

[0003] However, existing technologies still have the following problems:

[0004] First, most existing dynamic vision sensor modules are not convenient to adjust the horizontal angle. Many rely on manual adjustment, which is extremely inconvenient. In some large-scale security monitoring scenarios, if the monitoring angle needs to be adjusted, staff often have to climb to a high place to manually rotate the sensor. The process is cumbersome and time-consuming, making it difficult to respond quickly to changes in monitoring needs and failing to meet the requirements for flexible and timely adjustment of the monitoring range for different scenarios.

[0005] Secondly, existing dynamic vision sensor modules are usually inconvenient to install, and most only support specific installation methods, such as fixing them to preset installation points with bolts. This is extremely inconvenient in practical applications. When it is necessary to install them on some irregular or temporary object surfaces, quick installation cannot be achieved. In the field environment, if you want to temporarily fix the sensor to objects such as tree branches and rocks for environmental monitoring, the traditional installation method simply cannot be completed.

[0006] To address the aforementioned problems, the inventors proposed a dynamic vision sensor module to solve them. Utility Model Content

[0007] To address the issues of inconvenient horizontal angle adjustment and installation of dynamic vision sensor modules, the purpose of this invention is to provide a dynamic vision sensor module.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: a dynamic vision sensor module, including a protective bracket, a dynamic vision sensing component is provided inside the protective bracket, a support plate is provided above the protective bracket, a rotating shaft is rotatably provided on the lower surface of the support plate, and the lower end of the rotating shaft is fixedly connected to the protective bracket, a motor is fixedly provided on the upper surface of the support plate, and the output end of the motor passes through the support plate and is fixedly sleeved with a drive gear, and a driven gear is fixedly sleeved on the outer surface of the rotating shaft, and the driven gear and the drive gear are meshed together.

[0009] Preferably, the dynamic visual sensing component is symmetrically fixed with support shafts on both sides, and the support shafts are damped and rotatably connected to the protective bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a motor-driven gear transmission method to accurately and conveniently adjust the horizontal angle of the dynamic vision sensing component, meeting the needs of dynamic vision monitoring range in different scenarios.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-3 As shown, this utility model provides a dynamic vision sensor module, including a protective bracket 1. The protective bracket 1 is made of high-strength aluminum alloy, which has the advantages of light weight, high strength, and corrosion resistance. It can effectively protect the dynamic vision sensing component 2 while reducing the weight of the entire module, making it easy to install and carry. The dynamic vision sensing component 2 (which can be the MV-SC2016PM series produced by Hikvision, or any common cuboid dynamic vision transmission device on the market) is installed inside the protective bracket 1. A support plate 3 is provided on the upper part of the protective bracket 1. A rotating shaft 31 is rotatably provided on the lower surface of the support plate 3. The upper end of the rotating shaft 31 passes through the support plate 3 and is fixedly provided with a limiting plate 38, and the limiting plate 38 is rotatably connected to the support plate 3. The lower end of the rotating shaft 31 is fixedly connected to the protective bracket 1. A motor 32 is fixedly provided on the upper surface of the support plate 3, and the output end of the motor 32 passes through the support plate 3 and is fixedly sleeved with a drive gear 33. A driven gear 34 is fixedly sleeved on the outer surface of the rotating shaft 31, and the driven gear 34 and the drive gear are connected. The gear 33 is engaged. When it is necessary to adjust the horizontal angle of the dynamic vision sensing component 2, the motor 32 is started. The output end of the motor 32 drives the drive gear 33 to rotate. Since the drive gear 33 is engaged with the driven gear 34, the driven gear 34 will rotate with the rotation of the drive gear 33. The driven gear 34 is fixedly sleeved on the rotating shaft 31, so the rotating shaft 31 will also rotate. The lower end of the rotating shaft 31 is fixedly connected to the protective bracket 1. Therefore, the protective bracket 1 will rotate with the rotating shaft 31, thereby realizing the angle adjustment of the dynamic vision sensing component 2 in the horizontal direction.

[0021] The upper surface of the support plate 3 is symmetrically provided with limiting grooves 37. The outer surface of the rotating shaft 31 is symmetrically fixed with crossbars 35. The upper surface of the crossbars 35 is fixed with limiting posts 36, and the limiting posts 36 are locked in the limiting grooves 37. The lower surface of the crossbars 35 is fixed with connecting posts 39, and the lower end of the connecting posts 39 is fixed with connecting plates 310. The connecting plates 310 and the protective bracket 1 are connected by bolts. During the rotation of the rotating shaft 31, the crossbars 35 fixed on the outer surface of the rotating shaft 31 will rotate accordingly. The limiting posts 36 on the crossbars 35 slide in the limiting grooves 37 on the upper surface of the support plate 3, which plays the role of limiting and stabilizing the rotation of the rotating shaft 31. At the same time, the crossbars 35 are connected to the protective bracket 1 through the connecting posts 39 and the connecting plates 310, which further ensures the stability of the rotation process.

[0022] A clamping frame 4 is symmetrically fixed on one side of the support plate 3, and a stud 41 is threaded through the upper surface of the clamping frame 4. A knob 42 is fixed at the upper end of the stud 41, and a clamping plate 43 is rotatably mounted at the lower end of the stud 41. Anti-slip pads 44 are fixed on the lower surface of the clamping plate 43 and inside the clamping frame 4. The anti-slip pads 44 are made of rubber and have good elasticity and anti-slip performance. When the dynamic vision sensor module needs to be installed on other objects, the part to be installed is placed in the clamping frame 4, and then the knob 42 is rotated to drive the stud 41 to rotate. Since the stud 41 is threaded through the clamping frame 4, the rotation of the stud 41 will cause it to move up and down in a straight line, thereby driving the clamping plate 43 to move downward. The anti-slip pads 44 on the lower surface of the clamping plate 43 and inside the clamping frame 4 can increase the friction and firmly clamp the installation part, thereby realizing the installation and fixation of the module.

[0023] The dynamic vision sensing component 2 has symmetrically fixed support shafts 11 on both sides, and the support shafts 11 are damped and rotatably connected to the protective bracket 1. The dynamic vision sensing component 2 also has symmetrically fixed limit shafts 12 on both sides, and the limit shafts 12 are damped and slidably connected to the protective bracket 1. When it is necessary to adjust the pitch angle of the dynamic vision sensing component 2, the operator can manually apply a certain force to overcome the damping force of the support shafts 11, so that the dynamic vision sensing component 2 rotates around the support shafts 11. At the same time, the limit shafts 12 perform damped sliding within the protective bracket 1 to ensure the smoothness of the adjustment process. After adjusting to a suitable angle, the dynamic vision sensing component 2 can be maintained at that angle due to the damping effect.

[0024] Working principle: When it is necessary to adjust the horizontal angle of the dynamic vision sensing component 2, the motor 32 is started. The output end of the motor 32 drives the drive gear 33 to rotate. Since the drive gear 33 is meshed with the driven gear 34, the driven gear 34 will rotate with the rotation of the drive gear 33. The driven gear 34 is fixedly sleeved on the rotating shaft 31, so the rotating shaft 31 will also rotate. The lower end of the rotating shaft 31 is fixedly connected to the protective bracket 1, so the protective bracket 1 will rotate with the rotating shaft 31, thereby realizing the angle adjustment of the dynamic vision sensing component 2 in the horizontal direction.

[0025] During the rotation of the shaft 31, the crossbar 35 fixed on the outer surface of the shaft 31 will rotate accordingly. The limiting post 36 on the crossbar 35 slides in the limiting groove 37 on the upper surface of the support plate 3, which plays the role of limiting and stabilizing the rotation of the shaft 31. At the same time, the crossbar 35 is connected to the protective bracket 1 through the connecting post 39 and the connecting plate 310, which further ensures the stability of the rotation process.

[0026] When it is necessary to adjust the pitch angle of the dynamic vision sensing component 2, the operator can manually apply a certain force to overcome the damping force of the support shaft 11, so that the dynamic vision sensing component 2 rotates around the support shaft 11. At the same time, the limiting shaft 12 slides in the protective bracket 1 with damping to ensure the smoothness of the adjustment process. After adjusting to the appropriate angle, the dynamic vision sensing component 2 can be maintained at that angle due to the damping effect.

[0027] When the dynamic vision sensor module needs to be installed on other objects, place the part to be installed in the clamping frame 4, and then rotate the knob 42 to drive the stud 41 to rotate. Since the stud 41 is threadedly connected to the clamping frame 4, the rotation of the stud 41 will cause it to move up and down in a straight line, thereby driving the clamping plate 43 to move downward. The anti-slip pad 44 on the lower surface of the clamping plate 43 and inside the clamping frame 4 can increase the friction and firmly clamp the installation part, thus realizing the installation and fixation of the module.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
