Description

Technical Field

[0001] This invention relates to the field of industrial vehicle hardware design, specifically to the optimization of equipment structure for monitoring the safety status of vehicle drivers. Background Technology

[0002] Industrial vehicles generally refer to wheeled transport and lifting equipment used for material handling, stacking, traction, or loading and unloading operations within designated areas such as ports, warehouses, workshops, and construction sites. They differ from commercial transport vehicles that travel on public roads and primarily serve industrial and commercial processes such as manufacturing and logistics warehousing, making them indispensable key equipment in modern production and logistics systems.

[0003] Industrial vehicles are equipped with Driver Distraction Detection Systems (DDDS). These systems are active safety technologies that assess a driver's attention level by monitoring behavioral characteristics such as head posture, gaze direction, and facial expressions. The device aims to identify whether the driver deviates from normal operating postures, such as frequently turning their head, looking down, or staring at non-working areas for extended periods, thereby issuing warnings of distraction and reducing the risk of accidents caused by human error.

[0004] The core component of this device is the feature acquisition module, which is installed on the vehicle body. Its hardware can be an angle sensor, an optical sensor, or an occlusion sensor, used to directly acquire the driver's head angle data, thereby providing a data basis for subsequent system judgment.

[0005] However, this technical solution has two drawbacks: First, its feature acquisition module is often fixedly installed, making it impossible to flexibly adjust according to different drivers' height, posture, and seat position, resulting in poor monitoring angles or blind spots, affecting recognition accuracy. Second, the feature acquisition module is often a single-view sensor, which is prone to losing targets due to slight head movements of the driver or changes in lighting conditions, resulting in less than ideal monitoring stability. Summary of the Invention

[0006] The purpose of this invention is to provide a driver distraction warning device and industrial vehicles suitable for use in industrial vehicles. It can be flexibly adjusted according to the different heights and sitting postures of drivers, improving the accuracy and versatility of recognition; moreover, it has a wide and accurate field of view, making it less likely to lose sight of the target.

[0007] The present invention is achieved through the following technical solution: a driver distraction warning device suitable for industrial vehicles, comprising a vehicle connection port for connecting to the industrial vehicle, a connecting rod connected to the vehicle connection port, and a feature acquisition module connected to the connecting rod. A mounting plate is rotatably connected to the connecting rod. The mounting plate includes a base plate and a movable plate slidably connected to the base plate. The feature acquisition module includes multiple acquisition units mounted on the surface of the movable plate, and each acquisition unit includes a sensor.

[0008] As a preferred embodiment of the present invention, the plurality of sensors are arranged in a ring array.

[0009] As a preferred embodiment of the present invention, the acquisition unit includes a base mounted on the surface of the moving disk and a push plate slidably connected to the base, the sensor is mounted on the push plate, and the moving direction of the push plate is the radial direction of the moving disk body.

[0010] As a preferred embodiment of the invention, it further includes a connecting element that connects at least two of the push plates.

[0011] As a preferred embodiment of the present invention, the base plate includes a movable groove, and the movable plate includes a plate body and a movable column connected to the plate body.

[0012] As a preferred embodiment of the present invention, the movable slot comprises a plurality of single slots, which converge at the center of the base plate and are evenly spaced apart.

[0013] As a preferred embodiment of the present invention, the cross-section of the movable column is square.

[0014] As a preferred embodiment of the present invention, it further includes an auxiliary fastening device for assisting in connecting and securing the vehicle connection port to the industrial vehicle.

[0015] As a preferred embodiment of the present invention, the auxiliary fixing device includes a slide rail connected to the connecting port, a first slide plate and a second slide plate slidably connected to the slide rail, and the second slide plate is provided with a slot for the first slide plate to be inserted.

[0016] As a preferred embodiment of the present invention, the connecting rod includes a first rod connected to the connecting port and a second rod slidably connected to the first rod, and the mounting plate is connected to the second rod.

[0017] As a preferred embodiment of the present invention, the second rod includes a plurality of positioning ports arranged in the height direction, and the first rod is connected to a pull rod for inserting into the positioning ports, and a spring is sleeved on the pull rod.

[0018] As a preferred embodiment of the present invention, the base plate is provided with a rotating shaft rotatably connected to the connecting rod and a locking plate for abutting against the rotating shaft to prevent its rotation.

[0019] An industrial vehicle includes a main frame, on which a traveling device is provided, and on which the driver distraction warning device for industrial vehicles described above is installed.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The movable disc can be moved on the base plate to adjust the field of view, increasing the equipment's versatility for different drivers. Furthermore, the individual data acquisition unit contains multiple sensors, avoiding the risk of losing targets with a single sensor, and provides a wide field of view.

[0022] 2. The sensor is mounted on a push plate, which can move linearly, further expanding the adjustment range of the sensor.

[0023] 3. Using a common connector simplifies operation, reduces the number of steps required to adjust multiple sensors, and improves efficiency.

[0024] 4. The moving groove is shaped like a star, allowing for more flexible movement of the moving column over a wider area. Positioning is achieved through static friction, making operation convenient.

[0025] 5. Rod 1 and Rod 2 adopt a telescopic design with adjustable length; the base plate and connecting rod have a rotating design, which further enhances the flexibility of the acquisition module.

[0026] 6. The positioning of rod one and rod two is achieved through the positioning port and the pull rod, which is convenient to operate and relies on the spring to return, which is labor-saving and reliable. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0036] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this specification. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0037] Example 1: A driver distraction warning device suitable for industrial vehicles, such as... Figure 1 As shown, it includes a connector 1 and a connecting rod 2. Connector 1 is used for locking and connecting to components on the industrial vehicle body, such as at the top of a body rod. To enhance stability after connection, a securing device 3 is installed on connector 1. Figure 3 As shown, a slide rail 31 is fixedly installed on the connection port 1, and two slides slide therein, namely slide plate one 32 and slide plate two 33. When connection and fixation are required, slide plate one 32 and slide plate two 33 slide closer to each other, and slide plate two 33 is provided with a slot 34 for the end of slide plate one 32 to be inserted, thus completing the auxiliary connection and fixation of the vehicle body rod.

[0038] Connecting rod 2 also features a telescopic adjustment design, such as... Figure 2As shown in Figure 4, connecting rod 2 is a two-section telescopic rod design, with rod two 22 sliding within rod one 21. Rod two 22 has multiple positioning ports 221 at different height positions. Rod one 21 is equipped with a pull rod 23, on which a spring 24 is fitted. When the user overcomes the spring force and pulls out the pull rod 23, rod two 22 can slide and extend freely. After sliding to the designated position, the user releases the pull rod 23, which springs back under the drive of the spring force and inserts into the corresponding positioning port 221, thus completing the length adjustment of the entire connecting rod 2.

[0039] like Figure 2 As shown, a mounting plate is rotatably mounted at the lower end of rod 22, comprising a base plate 4 and a movable plate 5. A rotating shaft 71 is mounted on the base plate 4, which is rotatably connected to the lower end of rod 22 via the shaft 71, thereby enabling the base plate 4 to move... Figure 2 It rotates horizontally. A locking plate 72 is slidably provided on the surface of the base plate 4. The user can move the locking plate 72 with his / her finger so that it comes close to the rotating shaft 71 and abuts against it to lock the rotation angle.

[0040] The base plate 4 and the movable plate 5 are not designed to rotate, but rather to slide. Specifically, for example... Figure 5 As shown, the base plate 4 has a movable groove 41, which contains multiple individual grooves. These individual grooves are evenly spaced and converge at the center of the base plate 4, extending radially. The entire movable groove 41 is arranged in a star-shaped pattern. The movable disk 5 includes a disk body 52 and a movable column 51 protruding from its lower surface. The position of the entire movable disk 5 is adjusted by moving the movable column 51 within the movable groove 41.

[0041] The movable column 51 can be a square column with a square cross-section, which allows it to achieve relative stability in position after it moves into place in the movable groove 41, relying on the static friction between the surface of the column and the surface of the groove wall of the movable groove 41.

[0042] When the user moves the position of the moving disk 5 by moving the moving column 52 within the moving slot 41, the position of the sensor 63 in a certain direction may be too close to the driver. This problem can be avoided by extending the position of the sensor 63 by extending the push plate 62.

[0043] Specifically, the feature acquisition module is installed on the surface of the movable disk 5. In this embodiment, it includes multiple acquisition units 6. The multiple acquisition units 6 are arranged in a ring with uniform spacing. Each acquisition unit 6 has the same structure. The base 61 is fixedly installed on the movable disk 5, and the push plate 62 is slidably connected to the base 61. Its sliding direction and extension direction are both the radial direction of the movable disk 5. The sensor 63 is set on the push plate 62. Its specific implementation can be an angle sensor, optical sensor, occlusion sensor, or camera as in the prior art, used to directly acquire the driver's head angle data, thereby providing a data basis for subsequent system judgment.

[0044] At the same time, to improve the fit of the device, in order to reduce the problem of needing to adjust multiple sensors 63 in a certain direction individually, a common connector 8 is set up. The common connector 8 is connected to at least two push plates 62, which can be elastic elements with elastic contraction. It can drive at least two push plates 62 to move at the same time, saving time and achieving the purpose of rapid adjustment.

[0045] The system calculates the driver's head offset angle in real time using an algorithm and compares it with three preset thresholds (a1, a2, a3) to execute graded warnings.

[0046] When the driver's head deflection angle is less than a1, the system determines it to be in a normal state and there is no warning. When the deflection angle exceeds a1 but is less than a2, the system determines it to be a minor danger and issues a warning through a buzzer and an indicator light on the mounting plate. When the deflection angle exceeds a2 but is less than a3, the system determines it to be a moderate danger, and in addition to the buzzer and indicator light, the system will reduce the vehicle speed. When the deflection angle exceeds a3, the system determines it to be a severe danger, at which point it will not only trigger the buzzer and indicator light, but will also automatically reduce the vehicle speed to a safe speed and stop the vehicle.

[0047] On the other hand, an industrial vehicle is also provided, comprising a main frame on which a traveling device is mounted. The traveling device includes wheels, a steering wheel, etc. A body pole is provided on the main frame, and the driver distraction warning device mentioned above is installed on the body pole, i.e., the connecting port 1 is connected to the body pole.
