Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a portable video monitoring device. Background Technology

[0002] While traditional video surveillance equipment has addressed many security needs, playing a crucial role in urban monitoring and public spaces, it has also revealed several technical limitations in practical use. Firstly, although traditional PTZ (pan-tilt-zoom) monitoring equipment can adjust horizontal rotation and pitch, it falls short when dealing with emergencies or needing rapid blind spot coverage, especially when positioned directly beneath the device or behind obstacles, where its focusing speed and flexibility are significantly insufficient. Secondly, camera stability becomes critical when moving on uneven surfaces. Even high-speed vehicles or road bumps can directly cause blurry and unclear images. This often requires electronic image stabilization, but this can further affect image brightness and clarity, leading to a decline in image quality in practical applications. Finally, monitoring equipment integrating multiple sensor modules, such as cameras, radar, and supplementary lighting, often becomes bulky and complex due to the size and calibration challenges associated with their independent installation. This not only increases installation and maintenance costs but also adds to the technical difficulty of equipment optimization and functional integration. Therefore, we propose a portable video surveillance device. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Traditional PTZ monitoring equipment, while capable of horizontal rotation and pitch adjustment, falls short when dealing with emergencies or needing rapid coverage of blind spots, especially when positioned directly below the device or in corners behind obstacles, where its focusing speed and flexibility are significantly insufficient. Secondly, when the device moves on uneven surfaces, camera stability becomes a critical issue. Even high-speed vehicles or road bumps can directly lead to blurred and unclear images. This often requires electronic image stabilization, but this can further affect image brightness and clarity, resulting in a decline in image quality in practical applications. Finally, monitoring equipment integrating multiple sensor modules, such as cameras, radar, and supplementary lighting, often becomes bulky and complex due to the size and calibration challenges associated with their independent installation. This not only increases installation and maintenance costs but also adds to the technical difficulty of equipment optimization and functional integration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mobile video surveillance device includes a mobile track and a camera module. The camera module is mounted above the mobile track. A rotating base is provided at the top of the mobile track. A secondary swing arm is mounted on the rotating base. The camera module is connected to the end of the secondary swing arm.

[0006] Furthermore, a chassis is provided in the middle of the mobile track, the chassis has a built-in battery compartment, and a rotary motor is installed in the middle of the chassis, and the rotary motor drives the rotating base to rotate at an angle of 0°-360°.

[0007] Furthermore, the secondary swing arm is composed of a first-stage arm and a second-stage arm hinged together. A pitch motor is connected to one side of the first-stage arm, and the pitch motor drives the first-stage arm to pitch from 0° to 90°.

[0008] Furthermore, the second-stage arm is made of carbon fiber, and a telescopic rod is provided near the end of the second-stage arm. In its default state, the second-stage arm is folded to the side of the first-stage arm, and its maximum length when extended is 1.5m.

[0009] Furthermore, a camera module is hinged to the end of the second-stage arm, and the camera module has a flip angle of 0°-90° at the end of the second-stage arm.

[0010] Furthermore, an electromagnet housing is connected to the flange at the end of the second-stage arm. Several electromagnets are arranged at equal intervals on the electromagnet housing. A universal ball joint is connected to the electromagnet housing. A magnetic sheet is embedded in the bottom of the ball cup shell of the universal ball joint. The top of the electromagnet housing is magnetically connected to the ball cup shell of the universal ball joint. A camera module is connected to the top of the universal ball joint.

[0011] Furthermore, the diameter of the ball cup shell of the universal ball joint is larger than the diameter of the electromagnet shell. Four lugs are equidistantly arranged on the outer edge of the electromagnet shell, and a compression spring is installed on each of the four lugs. The other end of the compression spring is connected to the bottom of the ball cup shell of the universal ball joint.

[0012] Furthermore, the camera module is generally cylindrical in shape, with a camera located in the center and an annular base surrounding the camera. Rotatable fill light strips are distributed in a ring on the annular base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The two-stage swing arm structure combined with the 360° rotating base enables the camera module to achieve horizontal monitoring without blind spots and supports tilt adjustment to cover monitoring needs at different heights. In addition, the second-stage arm is made of carbon fiber, and its lightweight design allows it to be quickly deployed and supports the end camera module to rotate from 0° to 90°, effectively detecting blind spots directly below or behind obstacles that are difficult to cover by traditional equipment. At the same time, the telescopic rod design allows the second-stage arm to be retracted, reducing the size of the equipment when not in use and improving mobility.

[0015] 2. The electromagnet array precisely counteracts high-frequency vibrations by dynamically adjusting the magnetic force, and the universal ball joint allows the camera module to deflect in multiple directions to adapt to the impact of complex terrain; the compression spring group absorbs low-frequency large-amplitude vibrations, such as when crossing obstacles, to avoid rigid impact damage to the equipment. Compared with traditional rubber shock absorbers or pure electronic image stabilization (EIS), this structure is more efficient in physical shock absorption and does not lose image quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a mobile video surveillance device, including a mobile track 1 and a camera module 2. The camera module 2 is installed above the mobile track 1. A rotating base 101 is provided at the top of the mobile track 1. A secondary swing arm 102 is installed on the rotating base 101. The secondary swing arm 102 can expand the monitoring range by physical extension rather than simple rotation, solving the problem of "the line of sight being blocked by itself" in traditional pan-tilt units. Moreover, it does not increase the size of the device after folding. The camera module 2 is connected to the end of the secondary swing arm 102. The coaxial design of the camera module 2 reduces the size of the device and ensures that the field of view of multiple sensors is consistent, eliminating the need for post-calibration and alignment.

[0027] Example 2

[0028] like Figure 1-4 As shown, a chassis 103 is set in the middle of the mobile track 1. The chassis 103 has a built-in battery compartment. A rotary motor is installed in the middle of the chassis 103. The rotary motor drives the rotating base 101 to rotate at an angle of 0°-360°. The built-in battery compartment of the chassis 103 provides centralized power supply, reduces exposed cables, and lowers the failure rate.

[0029] The secondary swing arm 102 is composed of a first-stage arm 104 and a second-stage arm 105 hinged together. A pitch motor 106 is connected to one side of the first-stage arm 104, which drives the first-stage arm 104 to pitch at an angle of 0°-90°. The second-stage arm 105 is made of carbon fiber, which reduces weight and increases arm strength, making it suitable for complex outdoor environments. A telescopic rod 107 is provided near the end of the second-stage arm 105. In the default state, the second-stage arm 105 is folded to the side of the first-stage arm 104. The maximum length of the second-stage arm 105 when extended is 1.5m. A camera module 2 is hinged to the end of the second-stage arm 105, and the camera module 2 can be rotated at an angle of 0°-90° at the end of the second-stage arm 105.

[0030] An electromagnet housing 108 is connected to the flange at the end of the second-stage arm 105. Several electromagnets 109 are evenly spaced on the electromagnet housing 108. A universal ball joint 110 is connected to the electromagnet housing 108. A magnetic sheet is embedded in the bottom of the ball cup shell of the universal ball joint 110. The top of the electromagnet housing 108 is magnetically connected to the ball cup shell of the universal ball joint 110. A camera module 2 is connected to the top of the universal ball joint 110. The diameter of the ball cup shell of the universal ball joint 110 is larger than the diameter of the electromagnet housing 108. Electromagnets 109 are evenly spaced on the outer edge of the electromagnet housing 108. The camera module 2 is equipped with four lugs 111, each with a compression spring 112. The other end of the compression spring 112 is connected to the bottom of the ball cup shell of the universal ball joint 110. The camera module 2 and the secondary swing arm 102 adopt a double-layer shock absorption design, which combines mechanical and electromagnetic shock absorption. Physical-level stability can be achieved without electronic image stabilization, making it especially suitable for high-speed moving scenarios. The universal ball joint 110, together with the compression spring 112, absorbs large low-frequency vibrations. The electromagnet 109 array is attached to the base of the camera module 2, and high-frequency micro-vibrations are suppressed by dynamically adjusting the magnetic damping.

[0031] The camera module 2 has a cylindrical outer shell. A camera 201 is set in the middle of the camera module 2, and an annular base 202 is set around the camera 201. Rotatable fill light strips 203 are distributed in a ring on the annular base 202. The camera 201 and fill light strips 203 of the camera module 2 ensure that the illumination is synchronized with the camera's field of view, avoiding the optical deviation of the traditional distributed layout. The annular fill light strips 203 can be adjusted with the angle of the camera 201 to achieve uniform fill light without shadows, which is suitable for night or low light environments.

[0032] The working process of this utility model is as follows: When using a mobile video surveillance device, after the device is started, the mobile track 1 moves to the target area according to the instructions. The rotating base 101 rotates horizontally from 0° to 360° under the drive of the rotating motor, which drives the secondary swing arm 102 to adjust the monitoring direction. The first-stage arm 104 achieves 0°-90° pitch adjustment through the pitch motor 106, while the second-stage arm 105 can be extended to a maximum length of 1.5 meters. Through the hinge structure at the end, the camera module 2 is flipped downward from 0° to 90°, covering the blind spots that are difficult to detect by traditional pan-tilt units.

[0033] During movement or operation, the compression spring 112 absorbs the low-frequency large-amplitude vibration transmitted by the chassis 103, and the universal ball joint 110 allows the camera module 2 to deflect in multiple directions to buffer the impact force. At the same time, the array of electromagnets 109 dynamically adjusts the magnetic force according to the vibration sensor data, attracts the magnetic sheet at the bottom of the ball cup shell, actively cancels high-frequency micro-vibrations such as motor vibration, and ensures image stability without relying on electronic image stabilization.

[0034] Inside the cylindrical housing of the camera module 2, the camera 201 and the ring-shaped fill light strip 203 are arranged coaxially to ensure that the lighting and shooting field of view are consistent. The fill light strip 203 can rotate with the angle of the camera 201 to provide shadowless and uniform fill light, which is suitable for night or low light environments. All sensor data are transmitted to the control terminal through integrated cables, reducing the risk of failure of exposed wires and improving the reliability of the equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
