Description

Technical Field

[0001] This utility model belongs to the field of automotive equipment technology, and specifically relates to a shock absorption device and monitoring equipment for an in-vehicle anti-fatigue driving visual monitoring device. Background Technology

[0002] Driver fatigue refers to the physiological and psychological dysfunction that occurs after prolonged continuous driving, resulting in a decline in driving ability. Poor or insufficient sleep quality, coupled with long driving hours, easily leads to fatigue. Driver fatigue affects many aspects of a driver's attention, senses, perception, thinking, judgment, will, decision-making, and motor skills, greatly increasing the risk of traffic accidents.

[0003] Therefore, in order to avoid traffic accidents caused by fatigued driving, vehicles are usually equipped with in-vehicle fatigue driving vision monitoring devices. These devices mainly use cameras to monitor the driver's facial images to judge the driver's driving condition, and then use voice or light to warn the driver to avoid fatigued driving.

[0004] However, existing vehicle-mounted anti-fatigue driving vision monitors are usually fixed to the vehicle in a fixed manner. However, when the vehicle is in motion, it will bump and shake, which will make it impossible for the vehicle-mounted anti-fatigue driving vision monitor to accurately and clearly capture the driver's facial image, thus affecting the accuracy of the vehicle-mounted anti-fatigue driving vision monitor in judging driver fatigue. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a shock-absorbing device and monitoring equipment for an in-vehicle anti-fatigue driving visual monitor, aiming to solve the problem in the prior art that the bumps generated when the vehicle is driving make it impossible for the in-vehicle anti-fatigue driving visual monitor to accurately and clearly capture the driver's facial image, thus affecting the judgment of fatigue driving.

[0006] The shock absorption device for an in-vehicle anti-fatigue driving visual monitoring device proposed in this utility model includes a base plate, a longitudinal shock absorption component and a transverse shock absorption component disposed on the base plate;

[0007] The longitudinal vibration assembly includes two parallel elastic rings and a top plate disposed above the elastic rings. The top plate is used to connect to the vehicle-mounted anti-fatigue driving visual monitor. The elastic rings have openings above them, and the top corners of the top plate each have connecting parts extending outwards. The connecting parts have first rotating holes, and both ends of the elastic rings are placed in and adapted to the rotating holes. The bottom plate has a fixing seat, and the fixing seat has a second rotating hole. The bottom of the elastic ring passes through the second rotating hole and is rotatably connected to the second rotating hole.

[0008] The lateral damping component is connected to the bottom side of the elastic ring to dampen the lateral movement of the elastic ring.

[0009] The aforementioned shock-absorbing device for an in-vehicle fatigue driving vision monitor, by incorporating longitudinal and lateral shock-absorbing components, allows the monitor to be fixed to the vehicle. The shock-absorbing device dampens both longitudinal and lateral vibrations experienced by the monitor, minimizing its impact from vehicle vibrations. This enables the monitor to accurately and clearly capture the driver's facial image, thus accurately determining whether the driver is fatigued. Specifically, the monitor is connected to a top plate, with elastic rings parallel to each other at the top and bottom. The bottom of the elastic rings is connected to the bottom plate. When the vehicle vibrates, the elastic rings provide longitudinal cushioning to absorb the longitudinal vibrations. Simultaneously, the lateral shock-absorbing components, which move along the elastic rings, absorb the lateral vibrations. Through the combined absorption of these components, the monitor is protected from the effects of vehicle vibrations. Therefore, this invention solves the problem in existing technologies where vehicle bumps during driving prevent the in-vehicle fatigue driving vision monitor from accurately and clearly capturing the driver's facial image, thus affecting fatigue driving judgment.

[0010] In addition, the shock absorption device for an in-vehicle fatigue driving visual monitoring device proposed according to this utility model may also have the following additional technical features:

The vertical plate has guide holes adapted to both sides of the guide rods. Springs are sleeved on the guide rods on both sides of the vertical plate. The vertical plate is located outside the elastic ring. The bushing is located on the side of the vertical plate near the elastic ring and sleeved on the elastic ring.

[0013] Preferably, a plurality of the fixing seats are evenly distributed on the base plate, a limiting ring is provided on one side of the bottom of the elastic ring, and a limiting groove adapted to the limiting ring is provided on the fixing seat, with the limiting ring placed in the limiting groove.

[0028] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 5 The image shows a shock-absorbing device for a vehicle-mounted anti-fatigue driving visual monitoring device according to an embodiment of the present invention, including a base plate 10, a longitudinal shock-absorbing component 20 and a transverse shock-absorbing component 30 disposed on the base plate 10.

[0033] The longitudinal vibration assembly includes two parallel elastic rings 21 and a top plate 22 disposed above the elastic rings 21. The top plate 22 is used to connect the vehicle-mounted anti-fatigue driving vision monitor. An opening is provided above the elastic rings 21. A connecting part 23 extends outward from the top corner of the top plate 22. A first rotating hole 24 is provided on the connecting part 23. Both ends of the elastic rings 21 are placed in the rotating holes and are adapted to the rotating holes. A fixing seat 11 is provided on the bottom plate 10. A second rotating hole 12 is provided on the fixing seat 11. The bottom of the elastic rings 21 passes through the second rotating hole 12 and is rotatably connected to the second rotating hole 12.

[0034] The lateral damping component 30 is connected to the bottom side of the elastic ring 21 to dampen the lateral movement of the elastic ring 21.

[0035] Understandably, by setting the longitudinal damping component 20 and the lateral damping component 30, when the vehicle-mounted anti-fatigue driving visual monitor is fixed to the vehicle via the damping device, the damping device dampens the longitudinal and lateral vibrations experienced by the monitor, so that the monitor is basically unaffected by vehicle vibrations. This allows for accurate and clear acquisition of the driver's facial image, enabling accurate judgment of whether the driver is fatigued. Specifically, the monitor is connected to the top plate 22, and an elastic ring 21 is arranged parallel to the bottom of the top plate. The bottom of the elastic ring 21 is connected to the bottom plate 10. When the vehicle vibrates, the elastic ring 21 provides longitudinal buffering to absorb the longitudinal vibration of the vehicle. At the same time, the lateral damping component 30, which moves along the elastic ring 21, absorbs the lateral vibration on the elastic ring 21. Thus, the vibration is absorbed by the lateral damping component 30 and the longitudinal damping component, preventing the monitor from being affected by vehicle vibrations. Therefore, this utility model solves the problem in the prior art where the bumps generated when the vehicle is in motion prevent the vehicle-mounted anti-fatigue driving visual monitor from accurately and clearly acquiring the driver's facial image, affecting the judgment of fatigue driving.

[0036] Specifically, the transverse damping assembly 30 includes two symmetrically arranged bases 31, a sliding member 32 arranged on the bases 31, and a bushing 33 arranged on the sliding member 32. The bases 31 have a groove 311 in the middle and transversely arranged guide rods 34 on both sides of the bases 31. The sliding member 32 includes a slider 321 adapted to the groove 311 and a vertical plate 322 arranged on the slider 321. The vertical plate 322 has guide holes 323 adapted to both sides of the guide rods 34. The vertical plate 322 has springs 35 sleeved on the guide rods 34 on both sides. The vertical plate 322 is arranged outside the elastic ring 21. The bushing 33 is arranged on the side of the vertical plate 322 close to the elastic ring 21 and sleeved on the elastic ring 21. In practical implementation, the vehicle's vibration is absorbed by the elastic ring 21, which absorbs longitudinal vibration. Lateral vibration causes the elastic ring 21 to move, making it rotate relative to the first rotating hole 24 and the second rotating hole 12. It then acts on the sliding member 32 through the bushing 33. The vertical plate 322 on the sliding member 32 interacts with the spring 35, thereby absorbing lateral vibration and achieving the anti-vibration effect of the vehicle fatigue driving vision monitoring device.

[0037] Additionally, multiple mounting bases 11 are evenly distributed on the base plate 10. A limiting ring 25 is provided on one side of the bottom of the elastic ring 21. The mounting base 11 is provided with a limiting groove 13 that matches the limiting ring 25, and the limiting ring 25 is placed in the limiting groove 13. In specific implementation, the limiting ring 25 fixes the elastic ring 21 in a preset position, thereby preventing the elastic ring 21 from moving back and forth, causing the position of the shock absorption device to shift, thus affecting the monitoring angle of the vehicle-mounted anti-fatigue driving vision monitoring device.

[0038] Specifically, the elastic ring 21 is elliptical in shape, with its bottom middle section protruding upwards to form a clearance space, within which the base 31 is placed. By providing this clearance space, the lateral damping component 30 can be positioned below the top plate 22, thereby reducing the overall volume of the damping device and allowing for installation in a wider range of locations. Furthermore, the elastic ring 21 is typically made of elastic metal. By shaping it into an elliptical form, the ring smoothly absorbs and transmits longitudinal vibrations through its arc-shaped structure, preventing excessive localized vibrations caused by sharp edges, which would affect the vibration absorption effect and lead to stress concentration and damage at the edges.

[0039] Additionally, multiple friction rollers 36 arranged vertically and horizontally are provided on both sides of the slide groove 311. The slider 321 includes a main body 3211 and extensions 3212 arranged on both sides of the main body 3211. The extensions 3212 are positioned between the upper and lower rows of friction rollers 36. In specific implementation, the slider 321 is guided and limited by the abutment between the main body 3211 and the side wall of the slide groove 311. The extensions 3212 are positioned between the two rows of parallel friction rollers 36. The friction rollers 36 prevent the extensions 3212 from being worn down by friction over a long period of time. Furthermore, the direct rolling friction between the friction rollers 36 and the extensions 3212 reduces friction loss between them, further improving the service life of the slider 321.

[0040] Specifically, support portions 312 extend upwards from both sides of the base 31, and the guide rod 34 is connected to the two support portions 312 at both ends. By setting the support portions 312, the guide rod 34 can be suspended above the base 31. The guide rod 34 and the guide hole 323 cooperate to guide the movement of the vertical plate 322, so that the transverse damping component 30 dampes vibration along the direction perpendicular to the longitudinal damping component 20, thereby improving the transmission effect of transverse vibration and thus improving the damping and absorption effect of transverse vibration.

[0041] Additionally, one end of the spring 35 is connected to the support part 312, and the other end is provided with a collar 37 sleeved on the guide rod 34. In specific implementation, the collar 37 causes the spring 35 to abut against the vertical plate 322, rather than the spring 35 directly contacting the vertical plate 322. Thus, when the spring 35 is used for shock absorption, the guiding effect between the collar 37 and the guide rod 34 causes the spring 35 to be in the opposite direction to the lateral vibration, thereby improving the shock absorption effect of lateral vibration.

[0042] Specifically, the base plate 10 is provided with a plurality of evenly distributed mounting holes 14, which are used to engage with fasteners to fix the base plate 10 to the vehicle. In practical implementation, the base plate 10 is firmly fixed to the preset position on the vehicle by the engagement of the fasteners with the mounting holes 14 through the plurality of evenly distributed mounting holes 14.

[0043] In summary, the shock-absorbing device for an in-vehicle anti-fatigue driving visual monitor in the above embodiments of this utility model, by setting longitudinal shock-absorbing component 20 and lateral shock-absorbing component 30, allows the in-vehicle anti-fatigue driving visual monitor to be fixed to the vehicle by the shock-absorbing device. The shock-absorbing device dampens the longitudinal and lateral vibrations experienced by the monitor, so that the monitor is basically unaffected by vehicle vibration, thereby accurately and clearly capturing the driver's facial image to accurately determine whether the driver is fatigued. Specifically, the monitor is connected to the top plate 22, and an elastic ring 21 is arranged parallel to the bottom of the top. The bottom of the elastic ring 21 is connected to the bottom plate 10. When the vehicle vibrates, the elastic ring 21 will provide longitudinal buffering to absorb the longitudinal vibration of the vehicle. At the same time, the lateral shock-absorbing component 30, which moves along the elastic ring 21, absorbs the lateral vibration on the elastic ring 21. Thus, the vibration is absorbed by the lateral shock-absorbing component 30 and the longitudinal shock-absorbing component, preventing the monitor from being affected by vehicle vibration. Therefore, this invention solves the problem in the prior art that the bumps generated when a vehicle is in motion prevent the on-board anti-fatigue driving visual monitoring device from accurately and clearly capturing the driver's facial image, thus affecting the judgment of fatigue driving.

[0044] Furthermore, this utility model also proposes a monitoring device, including a vehicle-mounted anti-fatigue driving visual monitor 40, an adjustment seat 50 disposed below the vehicle-mounted anti-fatigue driving visual monitor 40, and a shock-absorbing device disposed below the adjustment seat 50. The shock-absorbing device is the same shock-absorbing device for the vehicle-mounted anti-fatigue driving visual monitor 40 described in the above embodiments. In practical use, the vehicle-mounted anti-fatigue driving visual monitor 40 is connected and fixed to the vehicle via the adjustment seat 50 and the shock-absorbing device. The observation and shooting angle of the vehicle-mounted anti-fatigue driving visual monitor 40 can be adjusted via the adjustment seat 50 to adapt the monitoring device to drivers of different heights and postures.
