Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically to a driving safety monitoring device for use in the driver's cab. Background Technology

[0002] With the rapid development of intelligent transportation technology, driving safety monitoring systems are playing an increasingly important role in ensuring driving safety and preventing traffic accidents. These systems typically collect information such as the driver's facial features and body movements through cameras, and combine this information with algorithms to analyze the driver's fatigue state, concentration, and dangerous operating behaviors (such as making or receiving phone calls, closing eyes, etc.), thereby issuing timely warnings and reducing the risk of accidents.

[0003] In mainstream driving safety monitoring equipment, cameras are mostly fixedly installed. However, drivers vary significantly in height, build, and driving posture, making it difficult for fixed-angle cameras to adapt to diverse driving postures. This can result in situations where the face or upper body is obscured by the steering wheel or seat, creating blind spots in the monitoring range. When drivers make significant movements (such as leaning forward when suddenly turning the steering wheel or bending down to pick up an item), their critical actions or states are more likely to exceed the monitoring range of the fixed camera, causing the system to miss or misjudge dangerous behaviors. To address these issues, some monitoring equipment uses a manually adjustable installation angle design, allowing users to adjust the camera position according to their own circumstances. However, in actual use, unavoidable vibrations during vehicle movement can easily cause the adjusted camera angle to shift, gradually deviating the monitoring perspective from the preset range. Furthermore, adjusting the camera during driving is not only inconvenient but also distracts the driver, increasing driving risks. Utility Model Content

[0004] The purpose of this utility model is to provide a driving safety monitoring device for the driver's cab, which has the advantages of adapting to the driver's height and sitting posture, and having no blind spots in collaborative monitoring, thus solving the problems of poor adaptability and blind spots in the existing fixed-angle cameras.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A driving safety monitoring device for a driver's cab includes a first fixing component and a second fixing component.

[0007] It is worth noting that by using a slider in conjunction with a sliding groove, the movement of the adjusting block can be limited, thereby improving the stability of the electric rod pushing the adjusting block to move.

[0008] Preferably, a protective plate is fixed to the upper end of the adjusting seat, a partition is fixed to the front end of the protective plate, and a groove is opened through the front and rear edges of the adjusting block. One end of the partition passes through the groove and is fixed to the front end of the adjusting seat. The protective plate is located directly above the electric rod, and the partition is located directly above the slide groove.

[0009] It is worth noting that the protective plate can protect the electric rod inside the adjusting seat. The partition plate passes through the groove and can protect the slide and the output end of the electric rod connecting to the adjusting block without affecting the movement of the adjusting block. It can also work with the groove to further limit the movement of the adjusting block and improve the stability of the movement of the adjusting block.

[0010] Preferably, a controller is installed at the top of the protective plate.

[0011] It is worth noting that the servo motor and electric rod can be controlled by the controller, thereby adjusting the angle and position of monitoring component one according to the monitoring screens of monitoring component one and monitoring component two, so as to automatically adjust during vehicle movement to avoid affecting monitoring.

[0012] Preferably, the monitoring component 1 includes a connecting seat 1 fixed to the outer wall of the rotating block, a monitor 1 installed on the outer wall of the connecting seat 1, a locking block 1 fixed to one end edge of the monitor 1 near the connecting seat 1, and a locking groove 1 opened on the outer wall of the connecting seat 1, the locking block 1 and the locking groove 1 being adapted to each other.

[0013] It is worth noting that: Monitor 1 can be aimed at the driver's face for accurate monitoring, Connector 1 is used to power Monitor 1 and transmit monitoring data, and the clip 1, together with the slot 1, can detachably fix Monitor 1 to the outer wall of Connector 1, thereby facilitating the disassembly and maintenance of Monitor 1.

[0014] Preferably, a plug is fixedly connected to the center of one end of the monitor near the connector, and a socket is provided on the outer wall of the connector, which corresponds to the plug.

[0015] It is worth noting that by inserting plug one into socket one, the corresponding pins of plug one and socket one can be made to fit together and connect, thereby ensuring a stable connection while facilitating the disassembly of monitor one and subsequent cleaning and maintenance of monitor one.

[0017] It is worth noting that the fixed plate can support the flip plate, and the spring can push one end of the flip plate to tilt up, thereby flipping the flip plate and causing the other end to drop, so that the second card block can be inserted into the corresponding second card slot, further improving the firmness of the monitor one and ensuring the stability of the monitor one during operation. Pressing the spring can flip the flip plate, causing the second card block to fall out of the second card slot, which facilitates the disassembly and maintenance of the monitor one.

[0018] Preferably, a vibration damping pad is fixed to the lower end of the fixing frame, and several corresponding holes are opened on the inner wall of the fixing groove and the outer wall of the adjusting seat.

[0019] It is worth noting that: the mounting bracket can be fixed above the dashboard in the cab, so that the monitoring component can be aligned with the driver's face. The vibration damping pad can buffer the mounting bracket when the vehicle is in motion, reducing the impact of vibration on the monitoring component. The holes opened on the mounting slot and the adjusting seat can be used to fix the adjusting seat in the mounting slot with pins and bolts, which facilitates the replacement of the mounting bracket. The mounting bracket of a suitable shape can be selected according to the external contour above the dashboard in the cab to ensure the stability of the mounting component.

[0020] Preferably, an alarm is installed on the outer wall of the fixing frame 2, and the monitoring component 2 includes a connecting seat 2 fixedly connected inside the fixing cylinder. A monitor 2 is installed on the outer wall of the connecting seat 2, and a plug 2 is fixedly connected to one end of the monitor 2 near the connecting seat 2. An insertion port 2 is opened on the outer wall of the connecting seat 2, and the insertion port 2 corresponds to the plug 2.

[0021] It is worth noting that: the second mounting bracket can be fixedly installed on the outer wall of the A-pillar of the cab to provide support for the second monitoring component. The alarm can sound an alarm to remind the driver when dangerous driving is detected. The second monitoring device is a wide-angle camera that can monitor the entire cab and the driver. The second connecting bracket can power the second monitoring device and receive monitoring data. Inserting the second plug into the second socket will make the pins fit together and connect them, which facilitates the connection between the second monitoring device and the second connecting bracket, and thus facilitates the disassembly and maintenance of the second monitoring device.

[0022] Preferably, the outer wall of the second monitor is fitted with a sleeve, and the sleeve is threaded onto the outer wall of the fixed cylinder.

[0023] It is worth noting that by installing the sleeve thread on the outer wall of the fixed cylinder, the second monitor can be fixed to the outer wall of the second connecting seat, thus ensuring the stability of the second monitor during operation while disassembling and maintaining it.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a fixing bracket to fix the adjustment component above the dashboard in the driver's cab. The output end of the electric lever can push the adjustment block to move back and forth along the inner wall of the adjustment seat. The output end of the servo motor can drive the rotating block to rotate. According to the driver's height and the distance between the dashboard and the dashboard, the servo motor drives the rotating block to flip, thereby adjusting the vertical flip angle of the monitoring component. In conjunction with the electric lever driving the adjustment block to move, the front and rear distance of the monitoring component can be adjusted, so that the monitoring component can be freely adjusted according to the situation. It can always monitor the driver's face while driving, improving the stability of the monitoring. Then, a fixing bracket can fix the monitoring component to the outer wall of the A-pillar in the driver's cab, which can monitor the entire driver's cab. This allows the monitoring component to work synchronously with the monitoring component, making it easier to confirm the driver's condition. This avoids misjudgment caused by single monitoring and allows the angle and position of the monitoring component to be adjusted according to the monitoring situation of the monitoring component, ensuring that the monitoring component is always aligned with the driver's face in the driver's cab, improving the monitoring effect.

Detailed Implementation

[0027] 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.

[0028] To address the issues of poor adaptability and blind spots in existing fixed-angle cameras, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-5 ; A driving safety monitoring device for a driver's cab includes a first fixing component and a second fixing component. The first fixing component includes a first fixing frame 301, with a fixing groove 303 formed at the center of its upper end. An adjusting component is installed within the fixing groove 303. The adjusting component includes an adjusting seat 101 fixedly installed within the fixing groove 303. An adjusting block 105 is slidably mounted on the inner wall of the adjusting seat 101. An electric rod 102 is fixedly connected to the inner wall of the rear end of the adjusting seat 101. The output end of the electric rod 102 is fixedly connected to the outer wall of the adjusting block 105. A rotating seat 106 is fixedly connected to the upper end. Rotating blocks 107 are rotatably installed on the inner walls of both sides of the rotating seat 106. A servo motor 108 is installed at the upper end of the rotating seat 106. The output end of the servo motor 108 is connected to the rotating shaft of the rotating block 107. A monitoring component one is installed on the outer wall of the rotating block 107. The fixed component two includes a fixed frame two 401. A fixed cylinder 402 is fixedly connected to the inner wall of the fixed frame two 401. The monitoring component two is installed inside the fixed cylinder 402. The fixed component one is installed above the dashboard in the cab, and the fixed component two is installed on the outer wall of the A-pillar in the cab.

[0029] The adjustment component can be fixed above the dashboard in the cab using mounting bracket 301. The output end of the electric lever 102 can push the adjustment block 105 to move back and forth along the inner wall of the adjustment seat 101. The output end of the servo motor 108 can drive the rotating block 107 to rotate. According to the driver's height and the distance to the dashboard, the servo motor 108 drives the rotating block 107 to rotate, thereby adjusting the up and down rotation angle of the monitoring component. In conjunction with the electric lever 102 driving the adjustment block 105 to move, the front and back distance of the monitoring component can be adjusted. This allows the monitoring component to be freely adjusted according to the situation, and can always monitor the driver's face while driving, improving the stability of the monitoring. The second monitoring component can be fixed to the outer wall of the A-pillar in the cab using mounting bracket 401, which can monitor the entire cab. This allows the second monitoring component to work synchronously with the first monitoring component, making it easier to confirm the driver's condition. This avoids misjudgment caused by single monitoring and allows the angle and position of the first monitoring component to be adjusted according to the monitoring situation of the second monitoring component, ensuring that the first monitoring component is always aligned with the driver's face in the cab, improving the monitoring effect.

[0030] Please see Figure 3 The lower inner wall of the adjusting seat 101 is provided with a sliding groove 103. The lower end of the adjusting block 105 is fixedly connected to a slider 104. The outer wall of the slider 104 fits against the inner wall of the sliding groove 103. The extension and retraction direction of the output end of the electric rod 102 is the same as the extension direction of the sliding groove 103. By using the slider 104 in conjunction with the sliding groove 103, the movement of the adjusting block 105 can be limited, thereby improving the stability of the electric rod 102 pushing the adjusting block 105 to move. The upper end of the adjusting seat 101 is fixedly connected to a protective plate 109. The front end of the protective plate 109 is fixedly connected to a partition plate 112. The front and rear edges of the adjusting block 105 are provided with through grooves. 111, one end of the partition plate 112 passes through the groove 111 and is fixed to the front end of the adjusting seat 101. The protective plate 109 is located directly above the electric rod 102, and the partition plate 112 is located directly above the slide 103. The protective plate 109 can protect the electric rod 102 in the adjusting seat 101. The partition plate 112 passes through the groove 111 and can protect the slide 103 and the output end of the electric rod 102 connected to the adjusting block 105 without affecting the movement of the adjusting block 105. It can also work with the groove 111 to further limit the movement of the adjusting block 105 and improve the stability of the movement of the adjusting block 105.

[0031] A controller 110 is installed on the upper end of the protective plate 109; the controller 110 can control the servo motor 108 and the electric rod 102, thereby adjusting the angle and position of the monitoring component 1 according to the monitoring screen of the monitoring component 1 and the monitoring component 2, so as to automatically adjust during vehicle movement to avoid affecting the monitoring.

[0032] Please see Figure 4The monitoring component includes a connecting seat 204 fixed to the outer wall of the rotating block 107. A monitor 201 is mounted on the outer wall of the connecting seat 204. A locking block 203 is fixed to one end edge of the monitor 201 near the connecting seat 204. A slot 206 is provided on the outer wall of the connecting seat 204, and the locking block 203 is adapted to the slot 206. The monitor 201 can be aimed at the driver's face for accurate monitoring. The connecting seat 204 is used to supply power to the monitor 201 and transmit monitoring data. The locking block 203, in conjunction with the slot 206, can detachably fix the monitor 201 to the outer wall of the connecting seat 204, thereby facilitating the disassembly and maintenance of the monitor 201.

[0033] A plug 202 is fixedly connected to the center of one end of the monitor 201 near the connector 204. The outer wall of the connector 204 has a socket 205, which corresponds to the plug 202. By inserting the plug 202 into the socket 205, the corresponding pins of the plug 202 and the socket 205 can be connected to each other, thereby ensuring a stable connection and facilitating the disassembly of the monitor 201, which is convenient for subsequent cleaning and maintenance of the monitor 201.

[0034] The left and right ends of the monitor 201 are fixed with fixing plates 207. A flip plate 209 is hinged to the inner wall of the fixing plate 207. A spring 208 is fixed to the outer edge of the fixing plate 207. One end of the spring 208 is fixed to one end of the flip plate 209. A locking block 210 is fixed to the other end of the flip plate 209. The left and right ends of the connecting seat 204 are provided with locking slots 211, which are adapted to the locking blocks 210. The flip plate 209 can be adjusted through the fixing plates 207. The spring 208 provides support and can push one end of the flip plate 209 to tilt up, causing the flip plate 209 to flip and the other end to drop down, thereby allowing the second locking block 210 to be inserted into the corresponding second locking slot 211, further improving the firmness of the monitor 201 and ensuring the stability of the monitor 201 during operation. Pressing the spring 208 can also flip the flip plate 209, causing the second locking block 210 to fall out of the second locking slot 211, facilitating the disassembly and maintenance of the monitor 201.

[0035] Please see Figure 5The lower end of the mounting bracket 301 is fixed with a vibration damping pad 302. The inner wall of the mounting groove 303 and the outer wall of the adjusting seat 101 are both provided with several corresponding holes. The mounting bracket 301 can be fixed above the dashboard in the cab, so that the monitoring component can be aligned with the driver's face. The vibration damping pad 302 can buffer the mounting bracket 301 when the vehicle is in motion, reducing the impact of vibration on the monitoring component. The holes on the mounting groove 303 and the adjusting seat 101 can be used to fix the adjusting seat 101 in the mounting groove 303 by means of pins or bolts, so as to facilitate the replacement of the mounting bracket 301. The mounting bracket 301 of a suitable shape can be selected according to the external contour above the dashboard in the cab to ensure the stability of the installation of the mounting component.

[0036] The vibration damping pad 302 is a rectangular sheet structure that adapts to the lower contour of the mounting bracket 301. The material adopts a three-layer composite structure: the bottom layer is oil-resistant EPDM rubber with a diamond-shaped anti-slip texture pressed on its surface, which can closely fit the plastic surface of the dashboard to prevent the vibration damping pad from shifting when the vehicle is bumpy, while also being resistant to the high temperature and oily environment of the cab; the middle layer is a metal damping interlayer, which quickly absorbs the low-frequency vibration of the vehicle engine through the difference in damping coefficient between metal and rubber, improving the low-frequency vibration damping efficiency compared to a single rubber pad; the top layer is high-elasticity nitrile rubber with an integrally molded hexagonal honeycomb structure inside, which can disperse the high-frequency vibration transmitted by the mounting bracket 301 through the deformation of the honeycomb structure, while reducing the overall weight of the vibration damping pad and avoiding pressure deformation of the dashboard after long-term use. In addition, stepped bolt holes are reserved at the positions of the mounting holes of the damping pad 302 corresponding to those of the mounting bracket 301. This not only does not affect the connection between the mounting bracket 301 and the instrument panel via bolts, but also buffers the local vibration stress at the bolts through the reinforcing ring, preventing the damping pad from cracking due to bolt compression, and further improving its service life.

[0037] Please see Figure 6 An alarm 403 is installed on the outer wall of the second mounting bracket 401. The second monitoring component includes a second connecting seat 502 fixed inside the second mounting cylinder 402. A second monitor 501 is installed on the outer wall of the second connecting seat 502. A second plug 504 is fixed to one end of the second monitor 501 near the second connecting seat 502. A second socket 505 is opened on the outer wall of the second connecting seat 502, and the second socket 505 corresponds to the second plug 504. The second monitoring component can be fixedly installed on the outer wall of the A-pillar of the cab through the second mounting bracket 401 to provide support for the second monitoring component. The alarm 403 can sound an alarm to remind the driver when dangerous driving is detected. The second monitor 501 is a wide-angle camera that can monitor the entire cab and the driver. The second connecting seat 502 can supply power to the second monitor 501 and receive monitoring data. The second plug 504 is inserted into the second socket 505 so that the pins can be connected to each other, which facilitates the connection between the second monitor 501 and the second connecting seat 502, thereby facilitating the disassembly and maintenance of the second monitor 501.

[0038] The outer wall of the second monitor 501 is fitted with a sleeve 503, which is threaded onto the outer wall of the fixed cylinder 402. By threading the sleeve 503 onto the outer wall of the fixed cylinder 402, the second monitor 501 can be fixed to the outer wall of the connecting seat 502, thereby ensuring the stability of the second monitor 501 during operation while disassembling and maintaining it.

[0039] Working Principle: During equipment installation, the first mounting component is installed by fixing the mounting bracket 301 above the dashboard in the cab. The vibration damping pad 302 at the lower end of the mounting bracket 301 can buffer the overall structure when the vehicle is in motion, reducing the impact of vibration on the monitoring component. The adjusting seat 101 is fixed in the mounting slot 303 with pins or bolts through the holes corresponding to the outer wall of the adjusting seat 101. The mounting bracket 301 can be replaced with a suitable one according to the outer contour of the dashboard to ensure stable installation. The second mounting component is installed by aligning the locking block 203 of the monitor 201 with the locking slot 206 of the connecting seat 204 and engaging it. At the same time, the plug 202 in the center of the monitor 201 is inserted. The connector 204's socket 205 enables power supply and data transmission connection; the spring 208 on the outer wall of the fixing plate 207 pushes the flip plate 209 to flip, causing the locking block 210 at the end of the flip plate 209 to engage with the slot 211 of the connector 204, further reinforcing the monitor 201 and preventing it from loosening during operation; the installation of the fixing component 2 and the monitoring component 2: the fixing bracket 401 is fixed to the outer wall of the A-pillar of the cab, and the monitor 501 is connected by inserting the plug 504 into the socket 505 of the connector 2 502. Then, the sleeve 503 is threaded onto the outer wall of the fixing sleeve 402 to limit and fix the monitor 501, ensuring that the monitoring component 2 is installed firmly.

[0040] During the adjustment phase, the initial position is adjusted as follows: the servo motor 108 and the electric rod 102 are activated by the controller 110 at the upper end of the protective plate 109; the output end of the electric rod 102 pushes the adjusting block 105 to move along the inner wall of the adjusting seat 101, and the slider 104 at the lower end of the adjusting block 105 slides along the slide groove 103. At the same time, the partition 112 passes through the groove 111 of the adjusting block 105. The two work together to limit the movement of the adjusting block 105, improve stability, and realize the front and rear distance adjustment of the monitor 201; the output end of the servo motor 108 drives the rotating block 107 to rotate in the rotating seat 106, thereby driving the monitor 201 to flip up and down. Combined with the front and rear distance adjustment, the monitor 201 is accurately aligned with the driver's face; automatic adjustment during driving: monitor 201 01 Real-time acquisition of driver's facial data, and monitor 201 captures the entire cab view from a wide-angle perspective. Both data are transmitted to controller 110. If controller 110 detects that monitor 201 is deviating from the driver's face (e.g., slight movement of the driver's body), it automatically controls electric rod 102 to adjust the position of adjustment block 105 and servo motor 108 to adjust the angle of rotating block 107, dynamically correcting the position and angle of monitor 201 to ensure accurate monitoring at all times and avoid affecting the monitoring effect due to vehicle movement or driver actions. During the adjustment process, protective plate 109 protects electric rod 102 in adjustment seat 101, and partition 112 protects slide 103 and the output end of electric rod 102, while not interfering with the movement of adjustment block 105.

[0041] The controller 110 integrates a composite control component consisting of a microprocessor, an image recognition module, and a drive control module. Its internal image recognition module can receive driver facial image data transmitted by monitor 1 201 and wide-angle view data of the cab transmitted by monitor 2 501 in real time. It uses a preset algorithm to identify whether monitor 1 201 is deviating from the facial monitoring area. After the recognition result is transmitted to the core microprocessor, the microprocessor combines preset parameters (such as the moving step size of the adjustment block 105 and the flip angle threshold of the rotating block 107) to output control commands to the drive control module. The drive control module then sends current signals to the electric pole 102 and the servo motor 108 to achieve dynamic correction of position and angle.

[0042] During the maintenance and disassembly stage, for monitor 1 201 maintenance: Press the end of the flip plate 209 near the spring 208 to compress the spring 208 and rotate the flip plate 209, causing the second locking block 210 to disengage from the second locking slot 211. Then pull monitor 1 201 outward to disengage plug 1 202 from socket 1 205 and locking block 1 203 from the first locking slot 206. Monitor 1 201 can then be removed for cleaning or repair. For monitor 2 501 maintenance: Unscrew the sleeve 503 on the outer wall of the fixing cylinder 402 and pull monitor 2 501 outward to disengage plug 2 504 from socket 2 505. Disassembly is then complete. The operation is convenient and facilitates subsequent maintenance work.
