Description

Technical Field

[0001] This invention relates to the field of dashcam technology, specifically a three-channel dashcam with an obstructable inner lens. Background Technology

[0002] A three-channel dashcam, as a standard vehicle electronic device, typically features front-view, rear-view, and in-vehicle monitoring cameras to simultaneously capture multi-directional video data of the vehicle. The in-vehicle camera primarily records the occupants' and driver's operating status inside the vehicle, providing internal data storage for driving scenarios.

[0003] In actual use, the interior of a car is a relatively private physical space. Most existing dashcams with in-car cameras use menu options within the system's software or electronic micro-switches on the casing to control the camera's start and stop. This simplistic software control logic means that even if the main control system experiences program lag, command delays, or abnormal background program retrieval, the camera's hardware surface remains open, and the image sensor may remain powered and continue capturing images. Users lack intuitive physical visual feedback, and it's difficult to accurately determine whether the camera is actually stopped based solely on software status indicators.

[0004] The method of manually attaching a cover to the outside of the lens only provides unilateral obstruction of the optical view and cannot intervene in the underlying recording electrical signals of the device. In this state, the image processing chip inside the dashcam and the in-vehicle light sensor still maintain the system process of recording a black screen, resulting in unnecessary storage space occupation. The existing device structure lacks a design that rigidly binds the mechanical action of the physical cover in front of the optical lens with the recording signal cutoff control of the internal circuitry, causing a disconnect between the physical protection of privacy in the vehicle and the electronic operation of the system.

[0005] Therefore, this invention proposes a three-channel dashcam with an internal lens that can be blocked to address the shortcomings of existing technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a three-channel dashcam with an internally obstructable lens. This solves the problem that the privacy protection control structure of the in-vehicle monitoring lens in existing dashcams is susceptible to interference from abnormal program operation while maintaining power-on acquisition, and that conventional manual physical covering cannot simultaneously cut off the underlying video recording electrical signal, resulting in a disconnect between optical line-of-sight obstruction and the internal electronic working state of the system.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a three-channel dashcam with an obstructable inner lens, comprising a bottom shell, a front shell on the front side of the bottom shell, a sliding plate slidably connected to the front side of the front shell, a magnet fixedly connected to each of the four corners of the front side of the sliding plate, an induction magnet fixedly connected to the center of the top of the front side of the sliding plate, multiple locking blocks fixedly connected to the rear side of the sliding plate, multiple magnets fixedly connected to the four sides of the rear side of the front shell, an induction hole opened at the bottom of the front side of the front shell, and limit grooves opened on the upper and lower sides of the front end of the front shell, with the multiple locking blocks slidably connected to the corresponding limit grooves, and a cable outlet opened on one side of both the front shell and the sliding plate.

[0008] Preferably, a display screen is fixedly connected to the front side of the skateboard, and a Hall sensor is fixedly connected to the bottom front side of the bottom shell.

[0009] Preferably, an inner lens module is fixedly connected to the front right end of the bottom shell, and multiple inner lens fixing posts are fixedly connected to the rear right end of the front shell, with the multiple inner lens fixing posts inserted into the inner lens module.

[0010] Preferably, the front side of the face shell is fixedly connected with multiple sliders at equal intervals, and the bottom of the bottom shell is provided with multiple buttons at equal intervals.

[0011] Preferably, an internal lens is fixedly connected to the front side of the internal lens module, and an external lens is fixedly connected to the rear left end of the bottom shell.

[0012] Preferably, a base is fixedly connected to the top right side of the bottom shell, and a rotating seat is rotatably connected to the outer side of the base. A TYPC interface is provided at the front right end of the rotating seat, and an earphone interface is provided at the front left end of the rotating seat.

[0013] Preferably, the bottom rear side of the bottom shell has multiple heat dissipation holes at equal intervals.

[0014] This invention provides a three-channel dashcam with an obstructable inner lens. It offers the following advantages:

[0015] 1. This invention, by setting a sliding panel structure, not only physically blocks the optical path of the in-vehicle viewfinder, but also uses sensors to detect changes in the physical quantity of the magnetic field and controls the mainboard to execute a power supply circuit cut-off command. This creates a protection mechanism that combines hardware shielding and power-off of the underlying circuitry, preventing unauthorized collection of in-vehicle image data when the device is in a state of network intrusion or software control failure.

[0016] 2. This invention employs a multi-point magnetic adsorption positioning structure on the mating end face of the shell and the slide plate, combined with a guide groove limiting component. After the slide plate moves to the designated covering position, it is locked by the physical adsorption force between the magnetic poles, which restricts the displacement freedom of the slide plate relative to the shell, counteracts the environmental vibration load generated under vehicle driving conditions, and maintains the structural stability of the optical path covering state.

[0017] 3. This invention integrates screen monitoring and privacy masking into a single movable structural component by mounting the display module on the front side of the movable panel base and using the cable penetration channel reserved in the side wall. This ensures the fatigue resistance of the cable under repeated bending. It also reduces the overall space occupied by the device's front-end suspension. Combined with the heat dissipation hole array arranged on the bottom side of the housing, it maintains the thermodynamic balance of the internal high-frequency electronic components under operating conditions.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example:

[0029] Please refer to Figures 1 to 8 This invention provides a three-channel dash cam with an obstructable inner lens, which solves the problem of unstable operation caused by the lack of rigid constraints in the synchronous linkage structure of physical obstruction of privacy of the inner lens and electrical signal recording stop in dash cams.

[0030] Please refer to Figure 1 , Figure 5 and Figure 6 The bottom shell 1 is fixedly connected to the front cover 4. The bottom shell 1 is used as a mounting base to support internal electronic components and external components. The front cover 4 is used to close the bottom shell 1 and provide guiding support for external sliding structural components.

[0031] Limiting grooves 7 are formed at both the upper and lower ends of the front side of the face shell 4 in the horizontal direction. A sliding plate 3 is slidably connected to the front side of the face shell 4. Multiple locking blocks 12 are fixedly connected to the rear side of the sliding plate 3. The multiple locking blocks 12 are respectively inserted into the limiting grooves 7 and slidably connected to the inner wall of the limiting grooves 7. The locking blocks 12 are constrained by the limiting grooves 7 and move along the length direction of the limiting grooves 7. The cooperation between the locking blocks 12 and the limiting grooves 7 limits and guides the lateral translation trajectory of the sliding plate 3. Multiple sliding strips 5 are fixedly connected at equal intervals on the front surface of the face shell 4. The rear side of the sliding plate 3 is attached to the outer surface of the multiple sliding strips 5 and slides smoothly along the surface of the sliding strips 5. The sliding strips 5 change the surface contact between the face shell 4 and the sliding plate 3 into line contact, reducing the contact area and reducing the frictional resistance when the sliding plate 3 moves.

[0032] Please refer to Figure 6 , Figure 7 and Figure 8 A display screen 2 is fixedly connected to the front surface of the skateboard 3. The display screen 2 moves synchronously with the skateboard 3. The display screen 2 is used to display the recording images of multiple cameras and the operation menu to the user. A ribbon cable outlet 8 is provided on the side wall of the main body of the face shell 4. A ribbon cable outlet 8 is provided at the corresponding position on the side wall of the skateboard 3. The connecting ribbon cable of the display screen 2 passes through the ribbon cable outlet 8 on the side wall of the skateboard 3 and the ribbon cable outlet 8 on the side wall of the face shell 4 and extends to the inside of the bottom shell 1 to be electrically connected to the internal motherboard. The ribbon cable outlet 8 provides clearance for the connecting ribbon cable to prevent the connecting ribbon cable from being pulled or squeezed during the reciprocating sliding of the skateboard 3.

[0033] Four magnets (10) are fixedly connected to the four corners of the front side of the slide plate 3. Multiple magnets (13) (6 in total) are fixedly connected to the four sides of the rear side of the faceplate 4. The positions of the magnets (10) and (2) on the corresponding sides are matched. The magnetic attraction generated when the magnets (10) and (2) are close together positions the slide plate 3 at its limit movement, preventing it from deviating from its working position due to vehicle bumps. An induction magnet (11) is fixedly connected to the center of the top front of the slide plate 3. A sensing hole 6 is provided through the bottom side. A Hall sensor 18 is fixedly connected to the bottom front side of the bottom shell 1. The Hall sensor 18 is used to monitor changes in the magnetic field. When the sensing magnet 11 slides with the slide plate 3 to be aligned with the sensing hole 6, the Hall sensor 18 detects the change in the polarity of the magnetic field generated by the proximity of the sensing magnet 11 through the sensing hole 6 and outputs a level switching signal to the motherboard. In the default state, the right magnet 10 and the right magnet 2 13 are attracted together. When a certain force is applied manually, the left magnet 10 and the left magnet 2 13 are attracted together.

[0034] Please refer to Figure 2 , Figure 4 and Figure 5 An inner lens module 17 is fixedly connected to the front right end of the bottom shell 1. The inner lens module 17 is used to carry and cover the optical components for in-vehicle photography. Multiple inner lens fixing posts 16 are vertically fixedly connected to the rear right end of the front shell 4. The multiple inner lens fixing posts 16 are respectively inserted into the pre-reserved mounting holes on the outside of the inner lens module 17. The multi-point insertion and cooperation between the inner lens fixing posts 16 and the inner lens module 17 restricts the displacement freedom of the inner lens module 17 in three-dimensional space, ensuring the structural stability of the inner lens module 17 under vehicle vibration conditions. An internal lens 20 is fixedly connected to the front interior of the inner lens module 17. The internal lens 20 faces the interior of the vehicle to obtain optical image information of the in-vehicle environment. An external lens 21 is fixedly connected to the rear left end of the bottom shell 1. The external lens 21 is set away from the internal lens 20 and faces the front of the vehicle. The external lens 21 obtains external road image data in front of the vehicle.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3A base 19 is fixedly connected to the top right side of the bottom shell 1. The base 19 protrudes upward and serves as the load-bearing connection base for the external mounting bracket. A rotating seat 22 is fitted on the outside of the base 19 and rotatably connected. The rotating seat 22 can rotate and deflect at multiple angles relative to the central axis of the base 19 to adjust the overall suspension and installation angle of the equipment. A TYPC interface 14 is provided at the front right end of the rotating seat 22. The TYPC interface 14 is connected to the vehicle power cable for power supply and digital signal cable transmission. A headphone jack 15 is provided at the front left end of the rotating seat 22. The headphone jack 15 is connected to an external audio device and provides a physical channel for audio signal output.

[0036] Multiple buttons 23 are evenly spaced at the bottom of the bottom shell 1. The tops of the buttons 23 protrude from the bottom surface of the bottom shell 1, and the bottom ends of the buttons 23 extend into the bottom shell 1 and are corresponding to the contact microswitches integrated into the internal motherboard. When the external physical press of the button 23 overcomes the internal rebound force, it triggers the contact microswitches at the bottom of the button 23, completing the electrical signal input for system menu settings and recording mode switching commands. Multiple heat dissipation holes 9 are evenly spaced on the rear side of the bottom of the bottom shell 1. The heat dissipation holes 9 penetrate the wall thickness of the bottom shell 1 and connect the internal and external physical spaces of the bottom shell 1. The heat dissipation holes 9 utilize the physical phenomenon of natural air convection to dissipate the heat generated by the high-frequency operation of the main control chip and image sensor inside the bottom shell 1 to the external environment, maintaining the internal electronic components within the rated operating temperature range.

[0037] Working principle: By applying a horizontal thrust from the outside, the slide plate 3 can overcome the static friction of the surface and move horizontally to the right along the slide bar 24. The locking block 12 fixed on the back of the slide plate 3 slides synchronously inside the limiting groove 7 of the face shell 4. The side wall of the limiting groove 7 abuts against the locking block 12 to guide and maintain the horizontal movement trajectory of the slide plate 3 without deflection. The slide plate 3 continues to move laterally to the right until the physical back plate of the slide plate 3 completely covers the built-in lens 20 installed inside the front side of the inner lens module 17, blocking the physical light path of light entering the surface of the lens of the built-in lens 20.

[0038] When the skateboard 3 moves to the position where it blocks the built-in lens 20, the four corner magnets 10 fixed at the front of the skateboard 3 simultaneously move to the front of the magnet 13 fixed at the rear of the faceplate 4. The magnets 10 and 13 attract each other with opposite magnetic poles to generate a constant magnetic force. The magnetic attraction locks the skateboard 3 in place relative to the faceplate 4, resisting external interference caused by vehicle vibration. The induction magnet 11 fixed at the top center of the front of the skateboard 3 simultaneously moves to the front of the induction hole 6 at the bottom front of the faceplate 4. The magnetic field generated by the induction magnet 11 passes through the induction hole 6. The action hole 6 acts on the Hall sensor 18 fixed at the bottom front side of the bottom shell 1. The Hall sensor 18 detects the change in the physical quantity of the magnetic field caused by the proximity of the sensing magnet 11 and converts the magnetic signal into an electrical signal by utilizing the local polarity reversal characteristics of magnetoelectricity. The Hall sensor 18 outputs a level switching signal to the internal main control chip. After receiving the level switching signal, the main control chip performs the action of cutting off the power supply circuit of the built-in lens 20 at the hardware circuit end, and simultaneously terminates the image acquisition and recording process of the built-in lens 20 at the system end. Through the sliding structure and the linkage of electrical signals, the physical hardware covering of the picture inside the carriage and the system software stopping recording are executed for dual control.
