Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment technology, and more specifically, to a stable driving recorder. Background Technology

[0002] For vehicles without built-in dashcams, owners typically need to install one to record video and audio during driving. Existing dashcams are fixed to the rearview mirror for optimal recording, usually using rigid clips. However, rearview mirrors vary in shape, making rigid clips unsuitable for all shapes. A few use elastic bands for better fit, such as Chinese patent application number 201610175435.9, which discloses a wireless car dashcam. This includes a dashcam body and a mounting base that matches the dashcam body. The mounting base has a binding device, but this elastic band is prone to fatigue and loosening under prolonged tension. The dashcam may loosen or even slip off during vehicle bumps or shaking. Therefore, we propose a dashcam with a stable connection to solve these problems. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a stable driving recorder, comprising a body, a strap, a sliding plate, an elastic element, and a limiting rod. One end of the strap is fixedly connected to the sliding plate, and the other end of the strap is fixedly connected to the body or another sliding plate. The body has a mounting cavity that is slidably connected to the sliding plate. The sliding plate and the elastic element are both accommodated in the mounting cavity. The elastic element abuts against the sliding plate. The limiting rod passes through the side wall of the mounting cavity and abuts against the front wall of the limiting rod.

[0004] When the body needs to be installed on the rearview mirror of the vehicle, rotate the limiting rod away from the sliding plate, pull the strap open, so that the sliding plate moves forward and squeezes the elastic member; when it is installed and the strap is released, the elastic member pushes the sliding plate backward to tighten the strap, and then rotate the limiting rod to abut against the sliding plate to limit the forward movement distance of the sliding plate.

[0005] Optionally, the left and right inner walls of the mounting cavity are recessed with limiting grooves, and the end of the sliding plate is limited in the limiting groove and slides back and forth along the limiting groove.

[0006] Optionally, it also includes a connecting rod that passes through both the front sidewall of the mounting cavity and the sliding plate, the connecting rod being threadedly connected to the rear sidewall of the mounting cavity, and the sliding plate sliding back and forth along the connecting rod.

[0007] Optionally, the elastic element is a spring, which is sleeved on the connecting rod, with its two ends abutting against the sliding plate and the front sidewall of the mounting cavity, respectively.

[0008] Optionally, there are two connecting rods and two springs distributed at the left and right ends of the sliding plate. Two limiting blocks are protruding from the sliding plate. The front end of the limiting block is adapted to abut against the front sidewall of the mounting cavity to limit the movement distance of the sliding plate.

[0009] Optionally, the upper end of the body is provided with a limiting port, the limiting port is connected to the mounting cavity, and the strap is inserted through the limiting port.

[0010] Optionally, a silicone strip or rubber strip is fixed on the side of the strap near the body to increase the friction between it and the rearview mirror.

[0011] Optionally, the front sidewall of the mounting cavity is provided with a mounting hole adapted to the limiting rod, and a self-locking nut is fixed in the mounting hole, the self-locking nut being connected to the limiting rod.

[0012] Optionally, the end of the limiting rod away from the sliding plate is provided with a knob, which is used to rotate the limiting rod to move the limiting rod back and forth.

[0013] Compared to existing technologies, the stable dashcam in this invention, by setting a limiting rod and using a strap instead of an elastic band, tightens the sliding plate while fitting the rearview mirror. The limiting rod, elastic element, and sliding plate work together to make axial movement of the limiting rod easier, facilitating dashcam installation. Compared to elastic bands, it is less prone to slackening, resulting in a more stable connection. After installation, it prevents the sliding plate from moving forward and squeezing the elastic element when the vehicle shakes, thus preventing the strap from loosening and ensuring a tighter connection between the dashcam and the rearview mirror.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0021] This utility model embodiment provides a stable connected dash cam, combined with Figures 1 to 3 As shown, the device includes a body 1, a strap 2, a sliding plate 3, an elastic element, and a limiting rod 5. One end of the strap 2 is fixedly connected to the sliding plate 3, and the other end of the strap 2 is fixedly connected to the body 1 or another sliding plate 3. The body 1 is provided with a mounting cavity 11 that is slidably connected to the sliding plate 3. The sliding plate 3 and the elastic element are both accommodated in the mounting cavity 11. The elastic element abuts against the sliding plate 3. The limiting rod 5 passes through the side wall of the mounting cavity 11 and abuts against the front wall of the limiting rod 5.

[0022] When the body 1 needs to be installed on the rearview mirror of the vehicle, rotate the limiting rod 5 away from the sliding plate 3, pull the strap 2, so that the sliding plate 3 moves forward and squeezes the elastic member; when it is installed and the strap 2 is released, the elastic member pushes the sliding plate 3 backward to tighten the strap 2, and then rotate the limiting rod 5 to abut against the sliding plate 3 to limit the forward movement distance of the sliding plate 3.

[0023] like Figure 1 As shown, in this embodiment, when the device 1 is installed on the rearview mirror of the vehicle, the front end of the device is aligned with the mirror surface of the rearview mirror, so that the camera at the front of the dashcam records the driving conditions outside the vehicle, while the mirror surface at the rear of the dashcam replaces the mirror surface of the rearview mirror. After pulling off the straps 2, the two straps 2 are passed through the left and right ends of the rearview mirror respectively. A silicone cover (not shown) is detachably connected to the upper opening of the mounting cavity 11. The silicone cover covers the internal structure of the mounting cavity 11, making it more aesthetically pleasing and dustproof.

[0024] like Figure 3As shown, in this embodiment, the limiting rod 5 is a threaded rod. When the dashcam is installed, the limiting rod 5 is first rotated so that it moves axially away from the sliding plate 3, so that the strap 2 can pull the sliding plate 3, which facilitates the strap 2 to fix the dashcam and the rearview mirror. Then, the limiting rod 5 is rotated so that it abuts against the sliding plate 3 to prevent the dashcam from shaking due to the sliding plate 3 squeezing the spring 4 when the vehicle is bumpy.

[0025] Compared to existing technologies, the stable dashcam in this invention, by setting a limiting rod 5 and using a strap 2 instead of an elastic band, tightens the sliding plate 3 by pushing the limiting rod 5 while fitting the rearview mirror. The combination of the limiting rod 5, the elastic element, and the sliding plate 3 makes the axial movement of the limiting rod 5 easier, facilitating the installation of the dashcam. Compared to the elastic band, it is less prone to elastic loosening, resulting in a more stable connection. After installation, it prevents the sliding plate 3 from moving forward and squeezing the elastic element when the vehicle shakes, thus preventing the strap 2 from moving forward and loosening, thereby making the connection between the dashcam and the rearview mirror tighter.

[0026] Optionally, the left and right inner walls of the mounting cavity 11 are recessed with limiting grooves 12, and the end of the sliding plate 3 is limited in the limiting grooves 12 and slides back and forth along the limiting grooves 12.

[0027] like Figure 3 As shown, in this embodiment, both the upper and lower ends of the sliding plate 3 are limited in the limiting groove 12. The bottom wall of the mounting cavity 11 is provided with a guide slope 121 on the side close to the limiting groove 12. The guide slope 121 is inclined downward and connects to the limiting groove 12. The sliding plate 3 and the mounting cavity 11 are interference fit. The guide slope 121 facilitates the installation of the sliding plate 3 in the limiting groove 12.

[0028] Optionally, it also includes a connecting rod 13, which passes through both the front sidewall of the mounting cavity 11 and the sliding plate 3. The connecting rod 13 is threadedly connected to the rear sidewall of the mounting cavity 11, and the sliding plate 3 slides back and forth along the connecting rod 13.

[0029] like Figure 3 As shown, in this embodiment, the rear end of the connecting rod 13 is threaded, and the rear wall of the mounting cavity 11 is provided with a threaded hole that matches the connecting rod 13, so that the connecting rod 13 can be installed in the mounting cavity 11. There are two connecting rods 13, and the two connecting rods 13 are slidably connected to the left and right ends of the sliding plate 3 respectively, so that the sliding effect of the sliding plate 3 is more stable.

[0030] Optionally, the elastic element is a spring 4, which is sleeved on the connecting rod 13, and the two ends of the spring 4 abut against the sliding plate 3 and the front sidewall of the mounting cavity 11, respectively.

[0031] like Figure 3 As shown, in this embodiment, when the user pulls off the strap 2, the strap 2 causes the sliding plate 3 to move closer to the front wall of the mounting cavity 11, causing the sliding plate 3 to compress the spring 4. When the user releases the strap 2, the spring 4 causes the sliding plate 3 to rebound until it abuts against the rear wall of the mounting cavity 11. Preferably, when the sliding plate 3 abuts against the rear wall of the mounting cavity 11, the spring 4 remains in a certain compressed state, continuously providing elastic force to press the sliding plate 3, making the mounting structure more stable.

[0032] Optionally, there are two connecting rods 13 and two springs 4, which are distributed at the left and right ends of the sliding plate 3. Two limiting blocks 31 are protruding on the sliding plate 3. The front end of the limiting block 31 is adapted to abut against the front side wall of the mounting cavity 11 to limit the movement distance of the sliding plate 3.

[0033] like Figure 3 As shown, the limiting block 31 protrudes from the front end face of the sliding plate 3. The two limiting blocks 31 are respectively close to the two springs 4. The limiting blocks 31 are used to protect the springs 4, prevent the springs 4 from being under extreme compression strength for a long time, and increase the service life of the springs 4. The limiting blocks 31 also act as reinforcing ribs, strengthening the structure of the sliding plate 3 and preventing the sliding plate 3 from breaking.

[0034] Optionally, the upper end of the body 1 is provided with a limiting port 14, the limiting port 14 is connected to the mounting cavity 11, and the strap 2 is inserted through the limiting port 14.

[0035] like Figure 3 As shown, in this embodiment, the width of the limiting opening 14 is adapted to the width of the strap 2, and the limiting opening 14 is located below the connecting rod 13. The strap 2 and the sliding plate 3 are fixed by adhesive or by ultrasonic welding. A gap is left between the bottom of the sliding plate 3 and the bottom wall of the mounting cavity 11, and the strap 2 passes through the gap and is fixed to the middle of the rear end wall of the mounting plate. When a connecting hole adapted to the connecting rod 13 is opened on the sliding plate 3, a corresponding connecting hole is also opened on the strap 2 to avoid the connecting rod 13. At the same time, the spring 4 will not touch the strap 2 when it moves axially.

[0036] Optionally, a silicone strip or rubber strip (not shown) is fixed to the side of the strap 2 near the body 1 to increase the friction between it and the rearview mirror. The strap 2 is made of nylon, which has low elasticity, so it is less likely to loosen after being tightened compared to an elastic band. At the same time, the soft nylon material can better conform to the rearview mirror. The silicone strip or rubber strip can increase the friction between the strap 2 and the rearview mirror, making the installation more stable.

[0037] Optionally, the front sidewall of the mounting cavity 11 is provided with a mounting hole adapted to the limiting rod 5. A self-locking nut (not shown) is fixed in the mounting hole, and the self-locking nut is connected to the limiting rod 5. The self-locking nut is accommodated in the mounting hole to increase friction and position the limiting rod 5, preventing the limiting rod 5 from rotating on its own under the push of the sliding plate 3.

[0038] like Figure 3 As shown, optionally, the end of the limiting rod 5 away from the sliding plate 3 is provided with a knob part 51, which allows the user to rotate the limiting rod 5 to move the limiting rod 5 back and forth.
