Description

Technical Field

[0001] This utility model belongs to the field of DMS installation technology, specifically relating to a vehicle DMS adjustment mechanism. Background Technology

[0002] A Driver Monitoring System (DMS) is an in-vehicle safety technology based on visual sensing and artificial intelligence algorithms. This system proactively identifies situations such as fatigued driving, distracted driving, unsafe driving behaviors (e.g., smoking, using a mobile phone), and abnormal driver identity by monitoring the driver's facial features, eye state, head posture, and behavioral patterns in real time. DMS can be combined with audible and visual warnings and vehicle control linkage functions to promptly issue alerts or take appropriate measures, effectively improving active driving safety and providing key state perception support for human-machine collaboration in autonomous driving. This technology is widely used in intelligent connected vehicles, commercial vehicle safety monitoring, and Advanced Driver Assistance Systems (ADAS), and is an important component in building an intelligent traffic management and safety protection system.

[0003] Traditional DMS uses a fixed structure, and due to differences in height and sitting posture, the DMS may not be able to recognize the driver's face in a timely manner.

[0004] To address the aforementioned problems, this application proposes a vehicle DMS adjustment mechanism. Utility Model Content

[0011] As a preferred embodiment of this utility model, the boss is close to the support plate, and the locking holes are arranged circumferentially along the axis of the threaded hole.

[0012] As a preferred embodiment of this utility model, the diameter of the smooth section of the bolt is smaller than the diameter of the support hole, and the front end of the boss is provided with a rounded corner, the width of which is greater than the width of the gap between the bolt and the support hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting an adjustment between the bracket and the DMS unit, the driver can adjust the angle of the DMS unit according to their height and sitting posture, thereby achieving the best recognition state and reducing the probability of misjudgment; 2. The bolts in the adjustment mechanism of this utility model connect the support plate and the upright plate, and also form a hinge.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figures 1-4 The present invention provides the following technical solution: a vehicle DMS adjustment mechanism, including a bracket 1 and a DMS body 2. The bottom of the DMS body 2 is injection molded with a support plate 21. The bracket 1 is sheet metal formed with a support leg 11 and a vertical plate 12. A bolt 3 is fixed on the vertical plate 12 and the bolt 3 also penetrates the vertical plate 12. The support plate 21 and the vertical plate 12 are hinged by the bolt 3. A spring 4 is also provided between the bolt 3 and the vertical plate 12. The support plate 21 has a locking hole 212, and the upright plate 12 has a protrusion 122 formed by sheet metal forming, which is connected to the locking hole 212 by spring 4.

[0017] The upright plate 12, support plate 21, bolt 3, and spring 4 are all provided in two symmetrically arranged sets. The two support plates 21 are located between the two upright plates 12, and the two bolts 3 are fixed to the support plate 21 at one end close to each other. The two sets of arrangements ensure the stable installation of the DMS body 2 on the bracket 1. The position of the bolt 3 is convenient for the operator to press inward with their hand. The two bolts 3 can be moved inward simultaneously with one hand, thereby disengaging the two locking holes 212 and the two bosses 122 at the same time, which is convenient for angle adjustment.

[0018] Furthermore, the bolt 3 includes a threaded section, a smooth section, and an end cap. The threaded section is used to fix the support plate 21, the smooth section is used to rotate and slide the upright plate 12, and the end cap is used to support the spring 4. At the same time, the end cap can also increase the contact area with the driver's hand during operation, making operation more effortless.

[0019] Furthermore, the support plate 21 has a threaded hole 211 that is screwed to the threaded section of the bolt 3, and the vertical plate 12 has a support hole 121 that is through-fitted to the smooth section of the bolt 3. After the threaded section and the threaded hole 211 are screwed to the bottom, the step formed between the threaded section and the smooth section of the bolt 3 can press against the side of the support plate 21, thereby stably connecting the bolt 3 to the support plate 21.

[0020] Furthermore, the spring 4 is fitted onto the outside of the bolt 3 and abuts against the outside of the upright plate 12 and the end cap of the bolt 3, so that the bolt 3, spring 4, upright plate 12, and support plate 21 can be quickly assembled during assembly.

[0021] Furthermore, the boss 122 is close to the support plate 21, and the locking holes 212 are arranged circumferentially along the axis of the threaded hole 211. The angle between two adjacent locking holes 212 is 15°, so as to achieve the purpose of precise adjustment at a small angle.

[0022] Furthermore, the diameter of the smooth section of bolt 3 is smaller than the diameter of the support hole 121, and the front end of the boss 122 is provided with a rounded corner, the width of which is greater than the gap width between bolt 3 and support hole 121. In this embodiment, the diameter of the smooth section of bolt 3 is slightly smaller than that of support hole 121. When bolt 3 is pressed inward, it pushes the support plate 21 to bend and deform. The gap of this diameter difference provides the bolt 3 with room to move, making it easier for the driver to operate. The rounded corner of boss 122 can facilitate the engagement of boss 122 and locking hole 212 while saving operating effort.

[0023] The working principle and usage process of this utility model are as follows: the support leg 11 and the upright plate 12 are punched and bent on the bracket 1, the support hole 121 is punched and formed, and the boss 122 is stamped. Assembly: The upright plate 12 and the support plate 21 are joined together, making the support hole 121 coaxial with the threaded hole 211. The spring 4 is sleeved on the outside of the bolt 3. After the bolt 3 passes through the support hole 121 from the outside of the upright plate 12, the front threaded section is screwed and tightened with the threaded hole 211. The other end of the upright plate 12 and the support plate 21 are also connected by the bolt 3 and the spring 4. Figure 1-2 In the normal state of the mechanism, the boss 122 is engaged with the locking hole 212 under the action of the spring 4, and the support plate 21 and the upright plate 12 on the same side are in contact. Angle adjustment: Press the two bolts 3 inward at the same time, the spring 4 is compressed, and the bolts 3 drive the lower part of the two support plates 21 to deform inward. At this time, the locking hole 212 disengages from the boss 122. Rotate the bolts 3 and the DMS body 2 on the upright plate 12, and after adjusting to the appropriate angle, loosen the bolts 3. Under the chamfering action of the boss 122, the nearest locking hole 212 and the boss 122 can be locked together, and then it remains stable under the action of the spring 4.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
