Description

Technical Field

[0001] This utility model relates to the field of vehicle monitoring technology, specifically a liftable monitoring device. Background Technology

[0002] Cameras are the most common type of vehicle roof monitoring equipment. They are usually installed in a conspicuous position on the roof to capture real-time images of the vehicle's surroundings. These cameras can provide high-definition video streams, helping drivers better understand the environment around the vehicle. They are widely used in fields such as public security, transportation, fire protection, and environmental protection. For example, in the public security field, they can be used for urban security monitoring and traffic violation capture; in the transportation field, they can be used for real-time monitoring of major traffic arteries such as highways and urban roads; in the fire protection field, they can be used for monitoring and command at fire scenes; and in the environmental protection field, they can be used for environmental monitoring and pollution source investigation.

[0003] There are two types of roof-mounted monitoring equipment: upright and inverted. The upright type refers to a single multi-section lifting rod, which has the advantages of small installation space and customizable height. The inverted type uses a push rod principle; the camera lies flat on the roof when not in use and is raised by pushing the rod when in use. Its advantage is that the vertical height is very small when it is folded down. However, both types are generally exposed to the external environment. When not in use, they are easily affected by direct sunlight, rain, dust accumulation, and even icing in winter, which affects image quality. Ultraviolet rays can cause the plastic around the lens to age and become brittle. Rainwater and dust mixed with the lens can adhere to the lens surface, causing blurry images and posing safety hazards.

[0004] Therefore, we propose a liftable monitor to solve the above problems. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Example

[0025] like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a lifting-type monitor, including a protective box 1 and a cover plate 2. The protective box 1 has a circular slot 3 on its left side, and the cover plate 2 has a cylindrical part 4 on its left side, which is hinged in the circular slot 3. A rotating shaft 5 is fixed in the cylindrical part 4, and an accordion-style protective cover 6 is installed at the opening of the cylindrical part 4. A servo motor 7 is fixed in the protective box 1, and a motor cover 8 is installed on the outside of the servo motor 7. The output shaft end of the servo motor 7 is connected to the rotating shaft 5 through a synchronous belt. An electric push rod 9 is fixed on the inner surface of the cover plate 2, and a bracket 10 is fixed on the output end of the electric push rod 9. A camera 11 is fixed on the bracket 10.

[0026] like Figure 1 As shown, in some embodiments, the bottom of the protective box 1 is provided with fixing holes 12 around its perimeter, and the bottom of the protective box 1 is provided with a cable outlet hole 13. The fixing holes 12 are fitted with screws to fix the monitor to the luggage rack on the roof of the vehicle. The cable outlet hole 13 refers to the hole for the lead-out cable or wire fixed on the electrical equipment, which is usually used to connect the electrical equipment to the power distribution line.

[0027] like Figure 3 As shown, in some embodiments, the circular slot 3 has shaft holes 14 on both the front and rear sides, and a bushing 15 is embedded in the shaft hole 14. The shaft hole 14 is a connecting structure, and the bushing 15 is a mechanical part used to reduce friction and wear, so as to prevent the shaft from being worn and scratched during operation and effectively extend the service life of the shaft.

[0028] like Figure 3As shown, in some embodiments, the cylindrical part 4 is provided with shaft heads 16 on both the front and rear sides, and the shaft heads 16 are movably inserted into the bushing 15. The shaft heads 16 are connecting structures, and after cooperating with the bushing 15, they are installed in the shaft hole 14, so that the cover plate 2 and the protective box 1 are hinged.

[0029] like Figure 3 As shown, in some embodiments, rubber gaskets 17 are installed on the front and rear sides of the cylindrical part 4, and the rubber gaskets 17 are located between the cylindrical part 4 and the circular slot 3. The rubber gaskets 17 are used to fill the gap between the end faces of the cylindrical part 4 and the circular slot 3 to reduce the wear and scratches on the cylindrical part 4 during operation.

[0030] like Figure 1 As shown, in some embodiments, a support roller 18 is installed in the cylindrical part 4, and the support roller 18 is close to the top of the synchronous belt connected to the servo motor 7 and the rotating shaft 5. The support roller 18 can support the belt body of the synchronous belt and prevent the synchronous belt from sagging or twisting due to gravity or load.

[0031] like Figure 1 As shown, in some embodiments, both the electric actuator 9 and the bracket 10 are provided with wire clamps 19, through which the cable of the camera 11 passes. The wire clamps 19 can effectively fix the wires. It is best to use spring cables for wiring the electric actuator 9 and the camera 11, which can shorten the wire length and reduce the space occupied in storage.

[0032] In use, the monitor is fixed to the roof rack of the vehicle using screws and mounting holes 12. The wiring of the servo motor 7, electric actuator 9, and camera 11 is led out from the cable outlet 13 and connected to the vehicle's electrical wiring (vehicle infotainment system). During operation, the servo motor 7 (whose main function is to achieve precise control of the position, speed, and torque of mechanical motion through a closed-loop control system, and whose core function is to convert electrical signals into high-precision angular displacement or angular velocity output) and the electric actuator 9 (an electric drive that converts the rotational motion of an electric motor into linear reciprocating motion) are controlled. The device is mainly used to achieve remote control, centralized control, or automatic control, so that the camera 11 is raised to the required height for remote monitoring. It can also finely adjust the pitch angle of the camera 11 by driving the servo motor 7. When transporting or not in use, the camera 11 can be tilted and put into the protective box 1. The protective box 1 and the cover plate 2 form a protective shell that can block rain, dust and other debris, protect the camera 11 from external environmental interference, extend the service life of the camera 11, and effectively reduce the frequency and cost of daily maintenance of the camera 11.

[0033] In summary, during operation, the servo motor 7 and electric actuator 9 are controlled to raise the camera 11 to the required height, enabling long-distance monitoring. The servo motor 7 can also be used to fine-tune the tilt angle of the camera 11. When not in use or during transport, the camera 11 can be tilted and stored in the protective box 1. The protective box 1 and the cover plate 2 form a protective shell that can shield the camera 11 from rain, dust, and other debris, protecting it from external environmental interference, extending its service life, and effectively reducing the frequency and cost of daily maintenance.
