Description

Technical Field

[0001] This utility model relates to the field of vehicle electronic equipment technology, and more specifically, it relates to a radar rotation adjustment mechanism for a dashcam. Background Technology

[0002] With the increasing popularity of intelligent driving assistance systems, more and more dashcams are integrating millimeter-wave or microwave radar to enable parking monitoring by triggering radar sensors when a moving object is detected. However, due to differences in windshield tilt angles among different car models and varying installation heights, fixed radar often struggles to achieve both optimal coverage and avoid false alarms.

[0003] In existing technologies, some dashcams use a gear meshing structure to achieve angle adjustment, but this has problems such as complex structure, large space occupation, multiple assembly processes, or loosening and failure after long-term use. Therefore, there is an urgent need for a radar rotation adjustment mechanism that is simple in structure, easy to assemble, and can stably lock the angle. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-5 As shown, this utility model provides a radar rotation adjustment mechanism for a dashcam, comprising:

[0029] Main body 1, with a camera and control circuit board installed inside;

[0030] The radar housing 2 and the main body 1 are rotatably connected by a rotating connection structure to adjust the detection angle of the radar. The radar is installed inside the radar housing 2.

[0031] A rotating connection structure is provided between the main body 1 and the radar housing 2. The rotating connection structure includes a rotating component 3. One end of the rotating component 3 is provided with a rotating head 31, and the other end is connected to either the main body 1 or the radar housing 2.

[0032] The radar housing 2 or the main body 1 is provided with a first mounting port 23, and the rotating head 31 is located in the first mounting port 23 and can rotate relative to the first mounting port 23.

[0033] Specifically, the main body 1 includes an upper shell 11 and a lower shell 12. The split design of the main body 1 facilitates mold forming and subsequent maintenance. The lower shell 12 has a first connection port 121, and the upper shell 11 has a second connection port 111 corresponding to the first connection port 121. The rotating component 3 is installed at the first connection port 121 and the second connection port 111. Both the first connection port 121 and the second connection port 111 have arc surfaces with the same radius. The rotating component 3 has corresponding arc segments with the same radius. When the rotating component 3 is installed on the main body 1, its arc segments mate with the arc surfaces of the first connection port 121 and the second connection port 111.

[0034] Specifically, the radar housing 2 includes an upper radar housing 21 and a lower radar housing 22. A first mounting port 23 is respectively opened at the same position on both the upper and lower radar housings 21 and 22. A limiting groove 231 is provided at one of the upper or lower radar housings 21 or 22. The first mounting port 23 on the upper or lower radar housing 21 has an arc-shaped surface that mates with the outer surface of the rotating head 31. To allow rotational space for the rotating component 3 and prevent it from colliding with the edge of the radar housing 2 and causing damage, a chamfer is provided at the first mounting port 23 on the upper or lower radar housing 21 or 22.

[0035] The upper housing 11 and the lower housing 12 are detachably connected, as are the upper radar housing 21 and the lower radar housing 22. Several snap-fit ​​fasteners are provided on the edge of one housing, and several slots are provided at corresponding positions on the edge of the other housing. The two housings are detachably connected via snap-fit ​​fasteners. Preferably, at key connection points of the main body 1 or the radar housing 2, screws are used to reinforce the connection between the two housings to ensure a tight fit. Alternatively, a pin connection can also be used for the detachable connection.

[0036] A radar is installed inside the radar housing 2, and a mode switching unit 5 is provided on the outside of the radar housing 2. The mode switching unit 5 is used to switch the radar to any one of the following states: off, first detection intensity mode, or second detection intensity mode, to meet the needs of different weather or road scenarios. In the first detection intensity mode, the radar has low sensitivity and is suitable for the short-range sensing range of normal mode. In the second detection intensity mode, the radar has high sensitivity and is suitable for the sensing range where a longer distance is required.

[0037] The radar housing 2 is equipped with a radar switch indicator 6 and an alarm indicator 7. The radar switch indicator 6 is used to display the working status of the radar, and the alarm indicator 7 is used to issue a warning when an anomaly is detected, so that users can understand the status of the equipment in real time and improve the intuitiveness of human-machine interaction.

[0038] Specifically, the outer surface of the rotating head 31 is an arc-shaped surface, and a limiting protrusion 32 is provided on the arc-shaped surface; the inner wall of the first mounting port 23 is correspondingly provided with a limiting groove 231. The limiting protrusion 32 and the limiting groove 231 cooperate to limit the rotation range of the rotating head 31. The limiting protrusion 32 is a cylinder, rectangle, or other shaped column with a certain height, and the limiting groove 231 is a rectangular groove, circular groove, or other shaped slot with a certain depth opened on the first mounting port 23. When the radar housing 2 rotates, the edge of the limiting groove 231 restricts its rotation range. When it rotates to the limit position, the limiting protrusion 32 abuts against the edge of the limiting groove 231, thereby limiting its further rotation in this direction. Through the engagement of the limiting protrusion 32 and the limiting groove 231, the user can steplessly adjust and automatically lock the radar angle within a certain angle range to prevent angle deviation caused by vehicle vibration. Preferably, since the limiting protrusion 32 is the main force-bearing structure, a reinforcing rib is provided at the connection between the limiting protrusion 32 and the outer surface of the rotating head 31 to enhance its strength.

[0039] Specifically, the other end of the rotating component 3 is detachably connected to the main body 1 or the radar housing 2, or integrally formed with the main body 1 or the radar housing 2, thus balancing assembly flexibility and structural strength. In this embodiment, the other end of the rotating component 3 is detachably connected to the main body 1.

[0040] Specifically, a positioning part 33 is provided at the end of the rotating component 3 away from the rotating head 31. The positioning part 33 is a raised rectangular plate with a certain thickness. A corresponding positioning groove 112 is provided on the main body 1 or the radar housing 2. The positioning part 33 cooperates with the positioning groove 112 to prevent the rotating component 3 from moving circumferentially or axially, thereby improving assembly accuracy. In this embodiment, the positioning groove 112 is formed in the upper housing 11. After the rotating component 3 is installed, its positioning part 33 is inserted into the positioning groove 112 of the upper housing.

[0041] Specifically, a damping pad 24 is provided on the inner wall of the first mounting port 23 on the opposite side of the limiting groove 231. The damping pad 24 can be made of silicone, rubber, or PU foam, and is used to provide rotational damping feel, prevent loosening and abnormal noise, and maintain angular stability under vibration. The damping pad 24 is a rectangular strip and is horizontally attached to the inner wall of the first mounting port 23 using adhesive.

[0042] Preferably, the positioning component has a through-hole groove, which allows the radar signal line to pass through the through-hole groove and be electrically connected to the control circuit board inside the main body 1, thereby reducing its weight and material costs while ensuring strength.
