Description

Technical Field

[0001] This invention belongs to the field of dashcam technology, specifically a split-type dashcam. Background Technology

[0002] A dashcam can be considered a car's black box. It records video and audio as soon as the engine is started, using a high-definition lens to capture images and sounds while the vehicle is in motion. In the event of an accident, it can immediately provide evidence to protect the driver's rights.

[0003] According to publication number CN223131963U, named "Dash Cam," it includes a dash cam housing, a side cover plate installed on one side of the housing, an external camera on one side of the side cover plate, a sleeve fixed to one side of the housing, a circular plate connected to the inside of the sleeve via a bearing, a connecting cover plate fixed to one side of the circular plate, a side housing fixed to one side of the connecting cover plate, an internal camera embedded in one side of the side housing, a grooved wheel fixed to one side of the circular plate, a rubber circular plate fixed to one side of the grooved wheel, a cylinder fixed to the inside of the sleeve, a push rod on one side of the cylinder, one end of the push rod extending into the inside of the cylinder, and a spring inside the cylinder. The beneficial effects are: the worm gear mechanism enables flexible adjustment of the dash cam's shooting angle, satisfying the shooting angle adjustment needs; the cooperation of the grooved wheel and the protrusion achieves the angle locking function, ensuring the dash cam remains stable during use and preventing shaking from affecting the shooting quality. However, as stated in the aforementioned document, since the dashcam is powered by the vehicle, it requires plugging into the dashcam's port to operate. During vehicle operation, vibrations are inevitable. These vibrations may cause the plug to gradually drift away from the port, leading to poor contact or even a complete disconnection. Once the plug separates from the port, the dashcam will malfunction and be unable to continuously record important information during driving, which undoubtedly severely impacts its operational stability. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a split-type dashcam.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a split-type dashcam, including a display screen and a camera, and further comprising: A clamping mechanism is located at the top of the display screen; The clamping mechanism includes a base rotatably connected to the top of the display screen. A mounting housing is rotatably connected inside the base. A fixed shell is fixedly installed on one side of the mounting housing. A limit rod is fixedly installed inside the fixed shell. Two hinge blocks are slidably fitted on the surface of the limit rod. A limit block is fixedly installed on one side of the two hinge blocks. A hinge rod is hinged inside the other side of the two hinge blocks. One end of the two hinge rods is hinged through a U-shaped block. The drive assembly is located inside the fixed housing.

[0006] Preferably, the driving assembly includes a rotating block rotatably connected inside the fixed housing. The surface of the rotating block is provided with a sliding groove. A lead screw located inside a U-shaped block is fixedly installed on one side of the rotating block, and the U-shaped block and the lead screw are threadedly connected. A connecting cylinder is slidably fitted on the surface of the rotating block. A ball located inside the sliding groove is rolledly connected inside the connecting cylinder. The connecting cylinder and the fixed housing are elastically connected by an elastic element.

[0007] Preferably, it further includes: A fixing mechanism is disposed inside the mounting housing. The fixing mechanism includes two movable blocks slidably connected inside the mounting housing. An insert block located inside the base is fixedly installed on one side of the two movable blocks facing each other. The two movable blocks are elastically connected by an elastic element two. An elastic element three is fixedly installed inside the mounting housing. A mounting frame is fixedly installed at the bottom end of the elastic element three. Compression wheels are rotatably connected to the inside of both sides of the mounting frame. A steel wire rope is fixedly installed at the top end of the mounting frame. A connecting plate is fixedly installed at one end of the steel wire rope, and the connecting plate is fixedly connected to one side of the top hinge block.

[0008] Preferably, it further includes: An adjustment mechanism is disposed inside the base. The adjustment mechanism includes a slide rail fixedly connected inside the base, a slide plate slidably connected to the surface of the slide rail, a rack fixedly installed at the bottom end of the slide plate, a gear located inside the base fixedly installed at the top end of the display screen, and the gear meshes with the rack, a moving ring fixedly installed at the top end of the slide plate, a motor fixedly installed inside the base, a push rod fixedly installed at the output end of the motor, and a protrusion located inside the moving ring fixedly installed at the bottom end of the push rod.

[0009] Preferably, the bottom of the inner and outer surfaces of the mounting housing are rotatably connected to guide wheels, and steel wire ropes are wound around the surface of the guide wheels.

[0010] Preferably, the limiting block is arc-shaped and has a rough surface, while the limiting rod is square and its surface fits against the inner wall of the hinge block.

[0011] Preferably, a square hole is provided on one side of the fixed shell, and the limiting block can slide inside the square hole.

[0012] Preferably, the groove is S-shaped, and the surface of the ball fits against the inner wall of the groove, and the surface of the ball is smooth.

[0013] Preferably, the slide groove is provided with a telescopic rod inside, and the slide groove is designed to be laterally symmetrical about the center of the rotating block.

[0014] Preferably, both of the moving blocks have an inclined surface on opposite sides, and the extrusion wheel surface has a smooth surface.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention involves pressing the connecting cylinder to slide it on the surface of the rotating block. During this sliding process, the connecting cylinder compresses the elastic element, which in turn pushes the ball bearing to move. The ball bearing slides inside the groove and drives the rotating block and the lead screw to rotate. The U-shaped block slides on the surface of the lead screw, which in turn pushes two hinge rods to rotate. These hinge rods then push two hinge blocks to move towards each other on the surface of the limiting rod. The hinge blocks, in turn, drive the limiting blocks to move towards each other. The plug is then inserted into the socket, and the connecting cylinder is released to allow the limiting blocks to fix it in place. Finally, the plug is fixed by the connecting cylinder driving the limiting blocks, thus ensuring the stability of the connection and preventing vibrations during vehicle operation from causing the plug to move away from the socket on the mounting housing side. This improves the stability of the display screen and camera operation.

[0016] This invention, by pressing the connecting cylinder to move the two hinge blocks, causes the top hinge block to pull the connecting plate upwards, which in turn pulls the steel wire rope. The steel wire rope then moves the mounting bracket and the pressing wheel upwards, causing the pressing wheel to move away from the surface of the moving block. The stretched elastic element then pulls the moving block and the insert block into the mounting housing. Simultaneously, as the plug is inserted into the socket, the bottom end of the mounting housing is inserted into the base, aligning the insert block with the groove inside the base. The connecting cylinder is then released, allowing the insert block to be inserted into the base and secured. Finally, pressing and releasing the connecting cylinder allows the insert block to move into or away from the groove inside the base. This greatly facilitates the operator's disassembly and assembly of the dashcam display and camera, improving efficiency and reducing potential damage to components due to complex operations, thus providing strong support for the daily use and maintenance of the dashcam.

[0017] This invention uses a drive motor to rotate a push rod, which in turn causes a protrusion to slide inside a moving ring. The rotating push rod then moves the moving ring, which in turn moves a sliding plate and a rack. The moving rack then rotates a gear, a display screen, and a camera, causing the base to misalign with the display screen and camera. This allows for adjustment of the angle of the display screen and camera. Finally, the drive motor causes the rack to rotate the gear, thereby adjusting the angle of the display screen and increasing the recording range of the camera, enabling the camera to better adapt to different working conditions.

Detailed Implementation

[0020] The technical solutions of 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.

[0021] like Figures 1 to 8 As shown, the present invention provides a split-type dashcam, including a display screen 1 and a camera 2, and further including: Clamping mechanism 3 is located at the top of display screen 1; The clamping mechanism 3 includes a base 301 fixedly connected to the top of the display screen 1. A mounting housing 302 is rotatably connected inside the base 301. A fixing housing 303 is fixedly installed on one side of the mounting housing 302. A limiting rod 304 is fixedly installed inside the fixing housing 303. Two hinge blocks 305 are slidably fitted on the surface of the limiting rod 304. A limiting block 306 is fixedly installed on one side of the two hinge blocks 305. A hinge rod 307 is hinged inside the other side of the two hinge blocks 305. One end of the two hinge rods 307 is hinged through a U-shaped block 308. The drive component 4 is located inside the fixed housing 303.

[0022] like Figure 4 and Figure 5 As shown, the drive assembly 4 includes a rotating block 401 rotatably connected inside the fixed housing 303. The surface of the rotating block 401 is provided with a sliding groove 402. A lead screw 403 located inside a U-shaped block 308 is fixedly installed on one side of the rotating block 401, and the U-shaped block 308 and the lead screw 403 are threadedly connected. A connecting cylinder 404 is slidably fitted on the surface of the rotating block 401. A ball bearing 405 located inside the sliding groove 402 is rotatably connected inside the connecting cylinder 404. The connecting cylinder 404 and the fixed housing 303 are elastically connected by an elastic element 406.

[0023] Using the above scheme: The operator presses the connecting cylinder 404 to make it slide on the surface of the rotating block 401. During this sliding process, the connecting cylinder 404 compresses the elastic element 406, causing it to move. The connecting cylinder 404 then pushes the ball 405 to move, and the ball 405 slides inside the groove 402. This sliding motion drives the rotating block 401 to rotate, which in turn drives the lead screw 403 to rotate. Since the lead screw 403 is threadedly connected to the U-shaped block 308, the U-shaped block... Block 308 will slide on the surface of lead screw 403. Since one end of the two hinge rods 307 is hinged through U-shaped block 308, the moving lead screw 403 will push the two hinge rods 307 to rotate. The rotating hinge rods 307 will push the two hinge blocks 305 to move towards each other on the surface of limit rod 304. The hinge blocks 305 will drive the limit blocks 306 to move towards each other. At this time, the plug for connecting the power supply can be inserted into the socket on one side of the mounting housing 302 to power on the recorder and start recording. After the connector is inserted, the connecting cylinder 404 can be released. The compressed elastic element 406 will push the connecting cylinder 404 to reset, and the ball bearing 405 will drive the rotating block 401 and the lead screw 403 to rotate in opposite directions. The U-shaped block 308 pulls the hinge block 305 to rotate, and the hinge block 305 will drive the limiting block 306 to move towards the surface of the plug, thereby fixing the plug. Finally, the connecting cylinder 404 drives the limiting block 306 to fix the plug, thereby ensuring the stability of the connection and preventing the plug from moving away from the socket on the side of the mounting housing 302 due to vibration during vehicle operation, thus improving the working stability of the display screen 1 and the camera 2.

[0024] like Figure 6 As shown, it also includes: The fixing mechanism 5 is disposed inside the mounting housing 302. The fixing mechanism 5 includes two movable blocks 501 that are slidably connected inside the mounting housing 302. An insert block 502 located inside the base 301 is fixedly installed on one side of the two movable blocks 501 facing each other. The two movable blocks 501 are elastically connected by an elastic element 2 503. An elastic element 3 504 is fixedly installed inside the mounting housing 302. A mounting frame 505 is fixedly installed at the bottom end of the elastic element 3 504. An extrusion wheel 506 is rotatably connected to the inside of both sides of the mounting frame 505. A steel wire rope 507 is fixedly installed at the top end of the mounting frame 505. A connecting plate 508 is fixedly installed at one end of the steel wire rope 507, and the connecting plate 508 is fixedly connected to one side of the top hinge block 305.

[0025] Using the above scheme: Through the design of the fixing mechanism 5, when the operator presses the connecting cylinder 404 to move the two hinge blocks 305, the top hinge block 305 will pull the connecting plate 508 upward, the connecting plate 508 will pull the wire rope 507 to move, and the moving wire rope 507 will drive the mounting frame 505 and the extrusion wheel 506 to move upward, while the elastic element 3 504 will be compressed, and then the extrusion wheel 506 will move away from the surface of the moving block 501. Then the stretched elastic element 2 503 will pull the moving block 501 and the insertion block 502 to retract into the mounting housing 302. When the plug is inserted into the socket, the bottom end of the mounting housing 302 is inserted into the base 301, and the insertion block 502 is aligned with the groove inside the base 301. When the connecting cylinder 404 is released, the hinge block 305 will reset, and the compressed elastic element 504 will push the mounting bracket 505 and the pressing wheel 506 down. During the movement of the pressing wheel 506, it will press and push the moving block 501 and the insert block 502 into the groove inside the base 301. When the moving block 501 moves, the elastic element 503 will be stretched, and then the insert block 502 will enter the groove, thereby fixing the mounting housing 302 inside the base 301. Finally, by pressing and releasing the connecting cylinder 404, the insert block 502 enters or moves away from the groove inside the base 301. This greatly facilitates the operator's disassembly and assembly of the dashcam display screen 1 and camera 2, not only improving the efficiency of disassembly and assembly, but also reducing the damage to components that may be caused by complex operations, providing a strong guarantee for the daily use and maintenance of the dashcam.

[0026] like Figure 7 and Figure 8 As shown, it also includes: An adjustment mechanism 7 is disposed inside the base 301. The adjustment mechanism 7 includes a slide rail 701 fixedly connected inside the base 301. A slide plate 702 is slidably connected to the surface of the slide rail 701. A rack 703 is fixedly installed at the bottom end of the slide plate 702. A gear 704 located inside the base 301 is fixedly installed at the top end of the display screen 1, and the gear 704 meshes with the rack 703. A moving ring 705 is fixedly installed at the top end of the slide plate 702. A motor 706 is fixedly installed inside the base 301. A push rod 707 is fixedly installed at the output end of the motor 706. A protrusion 708 located inside the moving ring 705 is fixedly installed at the bottom end of the push rod 707.

[0027] Using the above solution: Through the design of the adjustment mechanism 7, when the angle of the camera 2 needs to be adjusted during operation, the motor 706 can be driven to rotate the push rod 707. The push rod 707 will drive the protrusion 708 to rotate, and the protrusion 708 will slide inside the moving ring 705. Then, the rotating push rod 707 forms a stable rotation axis with the output end of the motor 706 as the center, thereby generating a pushing force, causing the moving ring 705 to move. The moving ring 705 drives the sliding plate 702 to move on the surface of the slide rail 701, and the sliding plate 702 drives the rack 703. The rack 703 and the gear 704 are meshed together. When the rack 703 moves, it drives the gear 704 to rotate. The rotation of the gear 704 causes the display screen 1 and the camera 2 to rotate, causing the base 301 to be misaligned with the display screen 1 and the camera 2. This allows for the adjustment of the angle of the display screen 1 and the camera 2. Finally, the drive motor 706 drives the rack 703 to push the gear 704 to rotate, thereby adjusting the angle of the display screen 1 and increasing the recording range of the camera 2, enabling the camera 2 to better adapt to the working needs under different conditions.

[0028] like Figure 3 and Figure 6 As shown, guide wheels 6 are rotatably connected to the bottom of the inner and outer surfaces of the mounting housing 302, and steel wire rope 507 is wound around the surface of the guide wheels 6.

[0029] The above solution is adopted: through the design of the guide wheel 6, when the wire rope 507 moves, the friction between the wire rope 507 and the guide wheel 6 is used to make the wire rope 507 drive the guide wheel 6 to rotate. The rotation of the guide wheel 6 can protect the wire rope 507, and the guide wheel 6 can limit the direction of movement of the wire rope 507.

[0030] like Figure 3 As shown, the limiting block 306 has an arc-shaped design and a rough surface. The limiting rod 304 has a square design and its surface is in contact with the inner wall of the hinge block 305.

[0031] The above solution is adopted as follows: By designing the limiting block 306, since the limiting block 306 is arc-shaped, it can fully fit the surface of the plug. Furthermore, the surface of the limiting block 306 is rough, which can increase the friction between it and the plug and ensure the fixing effect. In addition, the limiting rod 304 is square, which can limit the hinge block 305 when it moves. By limiting the hinge block 305, the U-shaped block 308 can slide stably on the surface of the lead screw 403.

[0032] like Figure 3 and Figure 4As shown, a square hole is provided on one side of the fixed shell 303, and the limiting block 306 can slide inside the square hole.

[0033] The above solution is adopted: By designing the fixed shell 303, since a square hole is opened on one side of the fixed shell 303, the limiting block 306 can slide inside the square hole when it moves. Thus, the fixed shell 303 will not interfere with the movement of the limiting block 306, and the limiting block 306 located inside the square hole fits against the inner wall of the square hole, thereby limiting the limiting block 306.

[0034] like Figure 3 and Figure 5 As shown, the slide 402 has an S-shaped design, and the surface of the ball 405 is in contact with the inner wall of the slide 402. The surface of the ball 405 is smooth. The slide 402 is equipped with a telescopic rod inside, and the slide 402 is symmetrical about the center of the rotating block 401.

[0035] The above solution employs the following design: Due to the S-shaped design of the slide groove 402 and the contact between the surface of the ball bearing 405 and the inner wall of the slide groove 402, the ball bearing 405 moves along the inner wall of the slide groove 402, thereby causing the rotating block 401 to rotate. The smoothly designed ball bearing 405 can roll smoothly inside the slide groove 402. Furthermore, the slide groove 402 is designed with a telescopic rod inside, which limits its movement when compressed. The slide groove 402 is also symmetrically designed about the center of the rotating block 401, so that the compressed slide groove 402 can simultaneously push the connecting cylinder 404 back to its original position, thus ensuring the stability of the connecting cylinder 404's movement.

[0036] like Figure 4 and Figure 6 As shown, both moving blocks 501 have a sloping design on opposite sides, and the surface of the extrusion wheel 506 is smooth.

[0037] The above solution is adopted: by designing the moving block 501, since the moving block 501 has a sloping design on both sides, the resistance between it and the extrusion wheel 506 can be reduced, ensuring that the extrusion wheel 506 can stably push the extrusion wheel 506 to move.

[0038] Working principle and usage process of this invention: First, the operator presses the connecting cylinder 404 to slide it on the surface of the rotating block 401. During the sliding process, the connecting cylinder 404 will squeeze the elastic element 406. Then, the connecting cylinder 404 will push the ball 405 to move. The ball 405 will slide inside the slide groove 402 and drive the rotating block 401 and the lead screw 403 to rotate. The U-shaped block 308 will slide on the surface of the lead screw 403. The lead screw 403 will push the two hinge rods 307 to rotate. The hinge rods 307 will push the two hinge blocks 305 to move towards each other on the surface of the limiting rod 304. The hinge blocks 305 will drive the limiting blocks 306 to move towards each other. At this time, the plug for connecting the power supply can be inserted into the socket on one side of the mounting housing 302. At the same time, when the operator presses the connecting cylinder 404 to move the two hinge blocks 305, the top hinge block 305 will pull the connecting plate 508 upward, the connecting plate 508 will pull the wire rope 507 to move, the wire rope 507 will drive the mounting bracket 505 and the extrusion wheel 506 to move upward, and then the extrusion wheel 506 will move away from the surface of the moving block 501. Then the stretched elastic element 503 will pull the moving block 501 and the insertion block 502 to retract into the mounting housing 302. At the same time as the plug is inserted into the socket, the bottom end of the mounting housing 302 is inserted into the base 301, and the insertion block 502 is aligned with the groove inside the base 301. After the plug is inserted and the plug 502 is aligned with the groove, the connecting cylinder 404 can be released. The compressed elastic element 406 will push the connecting cylinder 404 to reset, and the ball bearing 405 will drive the rotating block 401 and the lead screw 403 to rotate in the opposite direction. The U-shaped block 308 pulls the hinge block 305 to rotate. The hinge block 305 will drive the limit block 306 to move towards the surface of the plug, thereby fixing the plug. The compressed elastic element 504 will push the mounting bracket 505 and the extrusion wheel 506 to descend. During the movement of the extrusion wheel 506, it will squeeze and push the moving block 501 and the plug 502 towards the groove inside the base 301. When the moving block 501 moves, the elastic element 503 will be stretched, and then the plug 502 will enter the groove, thereby fixing the mounting housing 302 inside the base 301. Then the equipment is installed on the vehicle for recording work. When the angle of camera 2 needs to be adjusted during operation, the drive motor 706 drives the push rod 707 to rotate. The push rod 707 drives the protrusion 708 to slide inside the moving ring 705. Then, the rotating push rod 707 pushes the moving ring 705 to move. The moving ring 705 drives the sliding plate 702 and the rack 703 to move. The moving rack 703 drives the gear 704 and the display screen 1 and camera 2 to rotate, causing the base 301 to be misaligned with the display screen 1 and camera 2. This achieves the adjustment of the angle of the display screen 1 and camera 2, increases the recording range of camera 2, and finally completes the operation process.
