[0041] In modern road traffic, dashcams are crucial devices for ensuring driving safety and protecting rights, and their functionality is of paramount importance. While current dashcams are equipped with radar sensors and cameras to monitor the vehicle's surroundings, the limited rotation direction and angle of these sensors often result in insufficient coverage around the vehicle, creating significant blind spots. This not only affects the capture of critical environmental information but may also lead to insufficient evidence in determining liability in traffic accidents or dealing with staged accidents, thus failing to fully realize their intended purpose.

[0042] To address the blind spot problem in existing dash cams, this invention proposes a structurally optimized dash cam. By redesigning the installation and rotation structure of the radar 200 and camera, the angle can be adjusted more flexibly, thereby expanding the monitoring range and reducing blind spots.

[0043] This utility model proposes a vehicle dashcam.

[0044] Please see Figures 1 to 5 In one embodiment of this utility model, the dashcam includes:

[0045] The recorder body 100 has a first mounting part 110 on one side;

[0046] Radar 200, wherein a second mounting part 210 is provided on the side opposite to the first mounting part 110, and the second mounting part 210 is rotatably connected to the first mounting part 110;

[0047] The first camera 300 is rotatably connected to the second mounting part 210.

[0048] In this embodiment, a first mounting portion 110 is provided on one side of the recorder body 100; a second mounting portion 210 is provided on the side of the radar 200 opposite to the first mounting portion 110, and the second mounting portion 210 is rotatably connected to the first mounting portion 110; the first camera 300 is rotatably connected to the second mounting portion 210; the radar 200 can rotate vertically relative to the recorder body 100 to adjust its angle; the first camera 300 can rotate horizontally relative to the recorder body 100 to adjust its angle, thereby reducing the blind spots of the dashcam.

[0049] The second mounting part 210 is rotatably connected to the first mounting part 110. The rotatable connection between the first camera 300 and the second mounting part 210 can be a bushing fit, a hinge type, a ball joint connection, or other rotatable connection methods.

[0050] In existing dashcams, the angle adjustment structure between the radar 200 and the camera often becomes loose due to unstable connection, causing the monitoring angle to shift and increasing the monitoring blind spot.

[0051] Please see Figures 1 to 5 To improve the stability of the angle adjustment between the radar 200 and the camera, in one embodiment, the first mounting part 110 is provided with a first mounting groove 111, and the second mounting part 210 is rotatably connected to the first mounting groove 111.

[0052] In this embodiment, the first mounting groove 111 on the first mounting part 110 provides a suitable accommodating space for the second mounting part 210 of the radar 200, and the second mounting part 210 is inserted into the first mounting groove 111 to achieve a rotatable connection. This structural design makes the rotation of the second mounting part 210 within the first mounting groove 111 more directional and reduces radial sway.

[0053] When the vertical angle of the radar 200 needs to be adjusted, the second mounting part 210 rotates along the wall of the first mounting groove 111, that is, it rotates up and down in the vertical direction. The side wall of the first mounting groove 111 effectively limits the second mounting part 210, preventing deviation during rotation.

[0054] In practical use, installers can adjust the radar 200 vertically to align its detection direction with the road ahead, based on the tilt angle of the vehicle's windshield, and then rotate the first camera 300 to adjust the shooting angle. The entire adjustment process is smooth and the positioning is stable, and vibrations during vehicle movement do not easily change the adjusted angle. This further reduces the blind spots of the dashcam and improves the stability of the structural connection.

[0055] Please see Figures 1 to 5In one embodiment, specifically, the first mounting portion 110 includes a first extension portion 112, one end of the first extension portion 112 is provided with a first protrusion 113, the other end of the first extension portion 112 is provided with a second protrusion 114, a first mounting groove 111 is formed between the first protrusion 113, the first extension portion 112 and the second protrusion 114, and the second mounting portion 210 is rotatably connected to the first protrusion 113 and / or the second protrusion 114.

[0056] During the use of a dashcam, if the rotational connection between the radar 200 and the main body 100 of the dashcam relies solely on a simple shaft hole fit, it is prone to axial loosening or radial displacement under long-term vehicle vibration, affecting the accuracy of angle adjustment.

[0057] Please see Figures 1 to 5 This further enhances the stability of the rotating connection. In one embodiment, specifically, the second mounting portion 210 includes a first sidewall 211 and a second sidewall 212.

[0058] The first sidewall 211 is provided with a first connecting part 211a and a first limiting part 211b in sequence, and the first sidewall 211, the first connecting part 211a and the first limiting part 211b form a first slot 211c;

[0059] The second sidewall 212 is provided with a second connecting part 212a and a second limiting part 212b in sequence, and the second sidewall 212, the second connecting part 212a and the second limiting part 212b form a second slot 212c;

[0060] The first protrusion 113 includes a third sidewall 113a and a fourth sidewall 113b. The first protrusion 113 is provided with a first receiving cavity 113c, which is located between the third sidewall 113a and the fourth sidewall 113b.

[0061] The third sidewall 113a is provided with a first mounting hole 113d, the first connecting part 211a extends into the first mounting hole 113d, and the first slot 211c is rotatably connected to the third sidewall 113a.

[0062] The second protrusion 114 includes a fifth sidewall 114a and a sixth sidewall 114b, and a second receiving cavity 114c is provided inside the second protrusion 114, which is located between the fifth sidewall 114a and the sixth sidewall 114b.

[0063] The fifth sidewall 114a is provided with a second mounting hole 114d, the second connecting part 212a extends into the second mounting hole 114d, and the second slot 212c is rotatably connected to the fifth sidewall 114a.

[0064] In this embodiment, the first sidewall 211 and the second sidewall 212 of the second mounting portion 210 are respectively engaged with the third sidewall 113a of the first protrusion 113 and the fifth sidewall 114a of the second protrusion 114 through the first slot 211c and the second slot 212c, respectively. Simultaneously, the first connecting portion 211a and the second connecting portion 212a extend into the first mounting hole 113d and the second mounting hole 114d, respectively, forming a double-fit structure. This design makes the connection between the second mounting portion 210 and the first mounting portion 110 tighter, restricting axial movement through the slots and limiting radial displacement through the engagement of the limiting portion and the connecting portion with the mounting hole, thus providing a stable axis for rotation.

[0065] When the vertical angle of the radar 200 needs to be adjusted, the first connecting part 211a rotates smoothly within the first mounting hole 113d, and the first slot 211c rotates synchronously along the third side wall 113a. Simultaneously, the second connecting part 212a rotates accordingly within the second mounting hole 114d, and the second slot 212c rotates synchronously along the fifth side wall 114a. The tight and smooth fit between the components avoids jamming or misalignment during rotation, ensuring precise angle adjustment.

[0066] Even when the vehicle is traveling on a bumpy road, the connection between the second mounting part 210 and the first mounting part 110 remains stable, and the detection angle of the radar 200 will not change unexpectedly due to vibration. This allows the radar 200 to accurately cover the required area at all times, thus improving the reliability of the equipment.

[0067] Please see Figures 1 to 5 In one embodiment, a first limiting block 113e is provided on the inner wall of the first receiving cavity 113c, and a first locking block 211d is provided on the side of the first limiting part 211b away from the first connecting part 211a. The first locking block 211d is used to engage with the first limiting block 113e to limit the second mounting part 210; and / or,

[0068] The inner wall of the second receiving cavity 114c is provided with a second limiting block 114e, and the side of the second limiting part 212b away from the second connecting part 212a is provided with a second locking block 212d. The second locking block 212d is used to engage with the second limiting block 114e to limit the second mounting part 210.

[0069] In this embodiment, the first limiting block 113e on the inner wall of the first receiving cavity 113c can engage with the first locking block 211d on the first limiting part 211b, and the second limiting block 114e on the inner wall of the second receiving cavity 114c can also engage with the second locking block 212d on the second limiting part 212b. This mechanical engagement limits the rotation range of the second mounting part 210. When the second mounting part 210 is rotated to adjust the angle of the radar 200, the first locking block 211d moves synchronously with the first limiting part 211b. When a suitable angle is reached, the first locking block 211d engages with the first limiting block 113e, and at the same time, the second locking block 212d also engages with the second limiting block 114e, forming a positional positioning.

[0070] During the use of the dashcam, although the rotational connection between the second mounting part 210 and the first mounting part 110 has improved stability through multiple coordinations, the direct contact between the components may cause uneven frictional resistance during rotation. Long-term use may also cause gaps due to wear. At the same time, when the vehicle vibrates, abnormal noises may occur due to component collisions, affecting the user experience.

[0071] Please see Figures 1 to 5 To further optimize the smoothness and stability of the rotation process and reduce wear and abnormal noise, in one embodiment, the first connecting part 211a is provided with a second mounting groove 211e, and the second mounting groove 211e is provided with a first gasket 211f. One side of the first gasket 211f abuts against the third sidewall 113a, and the other side of the first gasket 211f abuts against the second mounting groove 211e. The second connecting part 212a is provided with a third mounting groove 212e, and the third mounting groove 212e is provided with a second gasket 212f. One side of the second gasket 212f abuts against the fifth sidewall 114a, and the other side of the second gasket 212f abuts against the third mounting groove 212e.

[0072] In this embodiment, the first gasket 211f in the second mounting groove 211e of the first connecting portion 211a abuts against the third sidewall 113a on one side and against the second mounting groove 211e on the other side. Similarly, the second gasket 212f in the third mounting groove 212e of the second connecting portion 212a abuts against the fifth sidewall 114a on one side and against the third mounting groove 212e on the other side. The gaskets can be made of an elastic material, which can both fill any small gaps that may exist during component mating and provide a cushioning effect during rotation.

[0073] When the second mounting part 210 rotates to adjust the angle of the radar 200, the first connecting part 211a rotates, causing the first shim 211f to deform slightly between the second mounting groove 211e and the third side wall 113a. The elasticity of the shim reduces the direct friction between the two, making the rotation smoother and avoiding wear caused by hard contact. Similarly, the second shim 212f plays the same role between the third mounting groove 212e and the fifth side wall 114a, reducing frictional resistance and buffering the impact force caused by vehicle vibration.

[0074] Please see Figures 1 to 5 In one embodiment, the second mounting part 210 is provided with a fourth mounting groove 220, and the inner wall of the fourth mounting groove 220 adjacent to the radar 200 is provided with a third mounting hole 221. The first camera 300 is provided with a third slot 310, and the third slot 310 is rotatably connected to the edge of the third mounting hole 221.

[0075] In this embodiment, the fourth mounting groove 220 on the second mounting part 210 provides a suitable mounting space for the first camera 300, and the edge of the third mounting hole 221 on the inner wall of the fourth mounting groove 220 forms a rotatable connection with the third slot 310 on the first camera 300. This structural design allows the third slot 310 to rotate smoothly around the edge of the third mounting hole 221, providing a stable axis of rotation for adjusting the horizontal angle of the first camera 300.

[0076] When it is necessary to adjust the horizontal angle of the first camera 300, rotating the camera will cause the third slot 310 to slide along the edge of the third mounting hole 221. The whole process is smooth and without jamming, and can be accurately adjusted to the required shooting angle. At the same time, the tight fit between the third slot 310 and the edge of the third mounting hole 221 effectively limits the radial wobbling of the camera, ensuring that the adjusted angle is not easily shifted due to vehicle vibration.

[0077] In practical applications of dashcams, relying solely on the monitoring range of the first camera 300 and radar 200 is sometimes insufficient to fully cover both sides of the vehicle and the complex surrounding environment, especially when turning or parking, as side blind spots may pose safety hazards.

[0078] Please see Figures 1 to 5 In one embodiment, it further includes:

[0079] A first connector 400, one end of which is rotatably connected to the fourth sidewall 113b;

[0080] The second camera 500 is rotatably connected to the other end of the first connector 400;

[0081] The second connector 600, one end of which is rotatably connected to the fifth sidewall 114a;

[0082] The third camera is rotatably connected to the other end of the second connector 600.

[0083] This embodiment aims to further expand the monitoring angle and reduce blind spots in the side and surrounding areas by adding a second camera 500 and a third camera, along with corresponding connectors.

[0084] In this embodiment, one end of the first connector 400 is rotatably connected to the fourth sidewall 113b, and the other end is rotatably connected to the second camera 500, forming a two-stage rotation structure; one end of the second connector 600 is rotatably connected to the fifth sidewall 114a, and the other end is rotatably connected to the third camera, also forming a two-stage rotation. This design allows the second camera 500 and the third camera to achieve multi-dimensional angle adjustment with the help of the connectors. The approximate direction can be adjusted by rotating the connectors, and fine angle calibration can be performed by rotating the cameras themselves relative to the connectors.

[0085] When monitoring the left side of the vehicle is required, first rotate the first connector 400 to turn the second camera 500 to the left, then rotate the second camera 500 itself to precisely adjust the shooting angle, ensuring coverage of the key area to the left rear or left front. Similarly, adjusting the second connector 600 and the third camera allows the third camera to accurately cover the monitoring range on the right side of the vehicle. The two-stage rotation is flexible and can be quickly adjusted according to different road conditions and driving needs, making operation convenient.

[0086] In this embodiment, when it is necessary to adjust the monitoring angle of the second camera 500, the first connector 400 can first be rotated around its connection point with the fourth side wall 113b. At this time, the first connector 400 will cause the second camera 500 to change its overall orientation, achieving a preliminary angle adjustment of the left side area of ​​the vehicle, such as turning the second camera 500 from its initial position to the left front or left rear. After the general direction is determined, the other end of the second camera 500 relative to the first connector 400 is rotated. Through this stage of rotation, the angle is finely calibrated, and the pitch or lateral tilt of the lens can be finely adjusted so that the second camera 500 is accurately aligned with key areas such as the left lane line, adjacent vehicles, or sidewalk.

[0087] When adjusting the third camera, the operating logic is the same as that of the second camera 500. First, rotate the second connector 600 around its connection point with the fifth side wall 114a, causing the third camera to rotate to the right of the vehicle to determine the approximate monitoring direction, such as the intersection to the right or the blind spot to the right rear. Then, rotate the other end of the third camera relative to the second connector 600 to make fine angle adjustments, ensuring that the lens can clearly capture details such as the blind spot of the right rearview mirror or pedestrians on the roadside.

[0088] This structural design effectively expands the monitoring dimensions of the dashcam, extending from a single frontal view to both sides of the vehicle, significantly reducing blind spots when turning, changing lanes, or parking. Simultaneously, the rotating connection between the connector and the sidewall maintains the stability of the previous structure. Combined with the rotational cooperation between the camera and the connector, the adjusted angle is not easily shifted even during vehicle vibrations, ensuring continuous stability of the monitoring image. In long-term use, this multi-camera collaborative monitoring method provides drivers with more comprehensive environmental information, improving driving safety and reliability.

[0089] The technical solution of this utility model adopts a first mounting part 110 on one side of the recorder body 100; a second mounting part 210 on the side of the radar 200 opposite to the first mounting part 110, the second mounting part 210 being rotatably connected to the first mounting part 110; the first camera 300 being rotatably connected to the second mounting part 210; the radar 200 being able to rotate vertically relative to the recorder body 100 to adjust its angle; and the first camera 300 being able to rotate horizontally relative to the recorder body 100 to adjust its angle, thereby reducing the monitoring blind spots of the dashcam.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
