Abstract
Description
Technical Field
[0001] The utility model relates to a scalding-proof driver monitoring camera structure, belonging to the technical field of monitoring cameras. Background Art
[0002] The driver monitoring camera structure is a device installed inside the vehicle to monitor the driver's status. The driver monitoring camera usually uses image recognition technology and artificial intelligence algorithms. The camera continuously captures the driver's image and then transmits the image data to the on-board computer system. The computer system uses a deep learning algorithm to analyze and process the image, identify the driver's various status characteristics, and compare them with preset standards to determine whether the driver is in an adverse state such as fatigue or distraction.
[0003] The current mass-produced driver monitoring cameras are mounted on the steering column of the car and have the following two design flaws:
[0004] First, the housing is made of metal, which feels hot when its temperature exceeds 50°C. The driver can easily come into contact with the pipe column, which can lead to poor user experience and even burns. This makes the monitoring camera structure unsafe.
[0005] Second, a metal shell is used to protect the PCBA, and then a plastic shell is used to cover the metal shell. This design requires a large space, increases the number of parts, and increases the total part cost and assembly cost, which in turn makes the cost of manufacturing and using the monitoring camera structure higher.

[0023] An embodiment of the present utility model provides a structure of a heat-insulating driver monitoring camera.
[0024] Please refer to Figure 1 、 Figure 2 、Figure 3 and Figure 4 , including a filter 1. The filter 1 is an optical element, usually made of materials such as glass, plastic or crystal. Its surface is coated with a specific optical thin film, which can selectively transmit or block light of specific wavelengths. It is mainly used to change the spectral characteristics of the light entering the optical system, such as selecting light in a specific wavelength range to pass through, eliminating stray light, adjusting the intensity of light, etc. On one side of the filter 1, there is a first fixing bracket 2. The first fixing bracket 2 cooperates with the second fixing bracket 8 and the housing 7. Relying on the characteristics of the metal material, it can quickly dissipate and absorb heat, and the metal material can be used to shield electromagnetic radiation. On the other side of the first fixing bracket 2, there is a heat-conducting silicone 3 for heat conduction. On the other side of the heat-conducting silicone 3, there is a lamp board 4 for supporting the light-emitting element. The light-emitting element can be used for supplementary lighting. On the other side of the lamp board 4, there is a sensor printed circuit board assembly 6, which is composed of a sensor, a printed circuit board and electronic components. The sensor among them is responsible for detecting specific physical quantities or environmental parameters. The printed circuit board provides electrical connection and mechanical support for the sensor and other electronic components. The electronic components are used for the camera to collect images. Outside the sensor printed circuit board assembly 6, there is a housing 7. The outside of the housing 7 is a plastic shell, and the inside of the housing 7 is a metal shell. The materials of the first fixing bracket 2 and the second fixing bracket 8 are both metal materials. The bottom of the housing 7 is connected to the second fixing bracket 8 through three fixing screws 5 among them.
[0025] Please refer to again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , it is worth specifically stating that the other two fixing screws 5 sequentially pass through the filter 1, the first fixing bracket 2 and are connected to the housing 7. The sensor printed circuit board assembly 6 is electrically connected to the lamp board 4. The upper surface of the sensor printed circuit board assembly 6 is in contact with the inner wall of the housing 7. The lower surface of the sensor printed circuit board assembly 6 is connected to the second fixing bracket 8. The sensor printed circuit board assembly 6 sequentially passes through the lamp board 4 and the first fixing bracket 2. The outer surface of the sensor printed circuit board assembly 6 is in clearance fit with the filter 1.
[0026] When the utility model is in use: When the sensor printed circuit board assembly 6 and the lamp board 4 are working, a large amount of heat will be generated. Among them, the heat dissipated by the lamp board 4 will be quickly conducted to the first fixing bracket 2 under the action of the thermal conductive silica gel 3. The first fixing bracket 2 made of metal can quickly absorb and dissipate heat depending on its high thermal conductivity and good heat capacity performance of its own metal characteristics. Therefore, part of the heat absorbed by the first fixing bracket 2 is dissipated by itself, and the other part is conducted to the housing 7 also made of metal. The metal material characteristics of the housing 7 also quickly absorb and dissipate heat depending on its high thermal conductivity and good heat capacity performance. Among them, the heat dissipated by the sensor printed circuit board assembly 6 will be directly conducted to the housing 7 made of metal and the second fixing bracket 8, and again quickly absorb and dissipate heat depending on the high thermal conductivity and good heat capacity performance of the metal material. And the plastic material shell on the outside of the housing 7 depends on the relatively weak intermolecular force of the plastic material. Unlike the metal material where there are a large number of free electrons that can efficiently transfer heat, the plastic molecules are mainly connected to each other by relatively weak forces such as van der Waals forces. This kind of force greatly hinders the conduction of heat, resulting in difficulty in quickly transferring heat in the plastic material, making the thermal conductivity of the plastic material low. The user will not get burned when touching the plastic shell on the outside, achieving the anti-scalding effect and avoiding the occurrence of scalding the driver, thereby achieving the effect of improving the use safety of the monitoring camera structure. Moreover, the housing 7 adopts an insert design of plastic plus metal material, with the metal material on the inside for shielding electromagnetic radiation. The insert method also simplifies the assembly process and saves the space of the product, achieving the cost reduction effect, reducing the number of parts, thereby reducing the total part cost and assembly cost, and further achieving the effect of reducing the manufacturing cost and use cost of the monitoring camera structure.
[0027] Working principle: Through the plastic material shell on the outside of the housing 7, depending on the low thermal conductivity of the plastic material, the anti-scalding effect is achieved, avoiding the occurrence of scalding the driver, thereby achieving the effect of improving the use safety of the monitoring camera structure. And through the insert design of plastic plus metal material, the insert method also simplifies the assembly process and saves the space of the product, achieving the cost reduction effect, reducing the number of parts, thereby reducing the total part cost and assembly cost, and further achieving the effect of reducing the manufacturing cost and use cost of the monitoring camera structure.
