Description

Technical Field

[0001] This utility model relates to the field of driver assistance equipment technology, specifically to a forklift driver fatigue detection audible and visual alarm device. Background Technology

[0002] In industrial production and logistics, forklifts are essential handling equipment used extremely frequently. Forklift drivers are highly susceptible to fatigue during prolonged continuous operation. Fatigue significantly reduces a driver's reaction time, judgment, and operational precision, thereby greatly increasing the risk of accidents such as collisions and rollovers. This can not only cause serious injury to the driver but also damage goods, the forklift, and surrounding facilities, resulting in substantial economic losses and negative social impacts for businesses.

[0003] Currently, while some devices exist on the market for detecting driver fatigue, most are single-function devices, only capable of detecting fatigue and providing simple alerts, lacking effective audible and visual alarm mechanisms. This makes it difficult to attract sufficient attention from drivers and other personnel in complex working environments. Furthermore, some devices with audible and visual alarms have poorly designed and arranged warning lights and speakers, resulting in ineffective alarms. In addition, during actual forklift use, detection components such as cameras are easily affected by dust and dirt, leading to decreased detection accuracy, and existing devices lack effective cleaning functions for these components. Therefore, developing a device that can effectively detect forklift driver fatigue, with good audible and visual alarm effects and automatic cleaning capabilities, is of significant practical importance. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an audible and visual alarm device for detecting fatigue in forklift drivers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forklift driver fatigue detection audible and visual alarm device, comprising a detection mechanism installed on the forklift for detecting the driver's fatigue state, and an audible and visual alarm mechanism installed on the detection mechanism. The audible and visual alarm mechanism includes a mounting base installed on the bottom of the forklift roof, a fixed column fixedly installed on the end of the mounting base, a rotating ring sleeved on the fixed column via a rotating component, multiple warning lights equally spaced on the side of the fixed column, and a speaker installed on the mounting base. The rotating ring has multiple openings corresponding to the multiple warning lights.

[0006] Preferably, the rotating assembly includes a rotating gear ring rotatably disposed in a rotating groove on the bottom end face of the mounting base, and a rotating gear disposed in the mounting base and meshing with the rotating gear ring, the rotating gear being driven by a rotating motor.

[0007] Preferably, the audible and visual alarm device further includes an identification camera disposed on the end of the fixed column away from the mounting base, a transparent cover disposed on the fixed column and fitted over the identification camera, and a cleaning component disposed on the rotating ring for cleaning the transparent cover, the transparent cover having a hemispherical structure.

[0008] Preferably, the cleaning assembly includes a cleaning rod with one end fixed to the top end of the rotating ring and one side attached to the surface of the transparent cover, and a cleaning component disposed in a cleaning groove on the side of the cleaning rod adjacent to the transparent cover.

[0009] Preferably, the cleaning component includes multiple rotating rods evenly spaced along the length of the cleaning groove opening, a cleaning strip sleeved on the multiple rotating rods, a drive structure for driving one of the rotating rods to rotate, and an auxiliary structure set on the cleaning rod to assist in removing dust from the cleaning surface of the cleaning strip. The cleaning surface of the cleaning strip is in contact with the surface of the transparent cover.

[0010] Preferably, the drive structure includes a drive gear disposed on the end of the rotating rod located at the bottom of the cleaning crank, a rotating gear disposed on the cleaning crank and meshing with the drive gear, and a drive wheel connected to the end of the rotating gear via a connecting rod. The surface of the drive wheel is perpendicularly attached to the side of the transparent cover. When the rotating ring drives the cleaning crank to rotate around the transparent cover, the drive wheel rotates around the transparent cover.

[0011] Preferably, the auxiliary structure includes an auxiliary rod that is rotatably inserted into a through hole in the bottom wall of the cleaning tank, a cleaning brush disposed on the auxiliary rod and in contact with the cleaning surface, a cleaning gear disposed on the end of the auxiliary rod, and a cleaning gear disposed on the end of one of the rotating rods and meshing with the auxiliary gear.

[0012] The beneficial effects of this utility model are:

[0013] 1. This forklift driver fatigue detection audible and visual alarm device consists of a mounting base at the bottom of the forklift roof, a fixed post at the end of the mounting base, multiple warning lights evenly spaced on the side of the fixed post, and a speaker mounted on the mounting base, forming a complete audible and visual alarm system. The evenly spaced warning lights emit warning light from different angles, enhancing the visual warning effect; the speaker emits a loud alarm sound, alerting the driver and other personnel audibly. Simultaneously, openings on a rotating ring correspond to the warning lights. Driven by the rotating component, the ring rotates, causing the openings to alternately align with the warning lights, achieving a flashing effect and further increasing the visibility of the warning, effectively attracting the driver's attention and reducing the risks associated with fatigued driving.

[0014] 2. The device has a recognition camera mounted on the end of the fixed column furthest from the mounting base, with a transparent cover fitted over it. A cleaning component is also mounted on the rotating ring. One side of the cleaning crank in the cleaning component is in contact with the surface of the transparent cover. As the rotating ring rotates, the cleaning crank rotates around the transparent cover, cleaning its surface. The cleaning strip in the cleaning component rotates under the drive of the drive structure, more effectively removing dust and stains from the transparent cover surface. The cleaning brush in the auxiliary structure rotates under the drive of the auxiliary rod, assisting in dust removal from the cleaning surface of the cleaning strip, ensuring the cleaning strip remains in good clean condition. This ensures the recognition camera can clearly capture the driver's status information, improving the accuracy of fatigue detection. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0023] Example 1: Reference Figures 1-5 The forklift driver fatigue detection audible and visual alarm device shown includes a detection mechanism installed on the forklift to detect the driver's fatigue state, and an audible and visual alarm mechanism installed on the detection mechanism. The audible and visual alarm mechanism includes a mounting base 1 installed on the bottom of the forklift roof, a fixed post 2 fixedly installed on the end of the mounting base 1, a rotating ring 5 sleeved on the fixed post 2 by a rotating component, a plurality of warning lights 8 equally spaced on the side of the fixed post 2, and a speaker 4 installed on the mounting base 1. The rotating ring 5 has a plurality of openings 6 corresponding one-to-one with the plurality of warning lights 8.

[0024] In this embodiment, the detection mechanism mounted on the forklift starts working simultaneously after the forklift is started. The detection mechanism typically includes multiple sensors, such as a camera, eye-tracking sensors, and steering wheel grip force sensors. The camera continuously captures images of the driver's face, analyzing the frequency of eye closure and yawning through image recognition technology. The eye-tracking sensor monitors the driver's eye movements to determine if there is inattention or a vacant stare. The steering wheel grip force sensor detects changes in the driver's grip on the steering wheel; a continuously weakening grip or abnormal fluctuations may indicate driver fatigue. The detection mechanism comprehensively analyzes the data collected by these sensors, determining whether the driver is fatigued based on a preset fatigue judgment algorithm and threshold. Once the detection mechanism determines that the driver is fatigued, it immediately sends a trigger signal to the audible and visual alarm mechanism. Upon receiving the signal, the audible and visual alarm mechanism emits a loud and warning sound, such as a rapid alarm or a specific voice prompt (e.g., "Driver is fatigued, please stop immediately and rest"), attracting the attention of the driver and other surrounding personnel through auditory means. Simultaneously, the rotating assembly begins operation, driving the rotating ring 5 to rotate. Since the rotating ring 5 has multiple openings 6 corresponding one-to-one with the warning lights 8 on the side of the fixed post 2, as the rotating ring 5 rotates, the openings 6 periodically overlap and offset from the warning lights 8. When the opening 6 overlaps with the warning light 8, the light emitted by the warning light 8 can propagate outwards through the opening; while when the opening 6 offsets from the warning light 8, the light is blocked by the rotating ring. This achieves the flashing effect of the warning lights 8. Multiple warning lights 8, evenly spaced on the side of the fixed post, flash simultaneously, emitting conspicuous light signals from different angles, further enhancing the visual warning effect. After the audible and visual alarm is triggered, the detection mechanism does not stop working but continues to monitor the driver's fatigue state. If the driver takes timely measures, such as stopping to rest, and the fatigue state is alleviated, the detection mechanism, after detecting that the relevant data has returned to normal, will send a stop signal to the audible and visual alarm mechanism. The speaker 4 will stop emitting sound, the rotating ring 5 will stop rotating, and the warning lights 8 will stop flashing. Conversely, if the driver continues to drive while fatigued, the audible and visual alarm system will continuously emit audible and visual alarms to constantly remind the driver and surrounding personnel until the driver recovers from fatigue or the forklift stops operating.

[0025] It is understandable that the rotation of the rotating ring 5 can be controlled in various ways. This embodiment provides the following solution:

[0026] like Figures 1-3 As shown, the rotating assembly includes a rotating gear ring 10 rotatably disposed in a rotating groove 9 on the bottom end face of the mounting base 1, and a rotating gear 11 disposed in the mounting base 1 and meshing with the rotating gear ring 10. The rotating gear 11 is driven by a rotating motor.

[0027] In this embodiment, the rotating gear 11 is driven by a motor to rotate. The rotating gear 11 meshes with the rotating gear ring 10, which in turn drives the rotating gear ring 10 to rotate, thereby driving the rotating ring 5 connected to the rotating gear ring 10 to rotate.

[0028] like Figure 1 and Figure 2 As shown, the sound and light alarm device also includes an identification camera installed on the end of the fixed column 2 away from the mounting base 1, a transparent cover 3 installed on the fixed column 2 and fitted onto the identification camera, and a cleaning component installed on the rotating ring 5 for cleaning the transparent cover 3. The transparent cover 3 has a hemispherical structure.

[0029] In this embodiment, the dust on the transparent cover 3 is cleaned by the cleaning component, which ensures the cleanliness of the surface of the transparent cover 3 so that the recognition camera can identify the driver's fatigue state. When the cleaning component is not working, it is located on the back of the image acquisition end of the recognition camera.

[0030] It is understandable that the surface of the transparent cover 3 can be cleaned in various ways. This embodiment provides the following solution:

[0031] like Figure 1 and Figure 2 As shown, the cleaning assembly includes a cleaning rod 7 with one end fixed to the top end of the rotating ring 5 and one side attached to the surface of the transparent cover 3, and a cleaning component disposed in a cleaning groove 12 on the side of the cleaning rod 7 adjacent to the transparent cover 3.

[0032] In this embodiment, the rotating ring 5 rotates directly, causing the cleaning crank 7 located on the rotating ring 5 to rotate around the transparent cover 3. Together with the cleaning component set in the cleaning tank 12, the dust on the transparent cover 3 can be cleaned, ensuring the cleanliness of the surface of the transparent cover 3.

[0033] like Figure 4 and Figure 5 As shown, the cleaning component includes multiple rotating rods 14 that are equally spaced along the length of the opening of the cleaning groove 12, a cleaning strip 13 sleeved on the rods of the multiple rotating rods 14, a driving structure for driving one of the rotating rods 14 to rotate, and an auxiliary structure set on the rod of the cleaning curved rod 7 to assist in removing dust from the cleaning surface of the cleaning strip 13. The cleaning surface of the cleaning strip 13 is in contact with the surface of the transparent cover 3.

[0034] In this embodiment, when cleaning dust on the transparent cover 3, the drive component drives one of the rotating rods 14 to rotate, which in turn drives the cleaning strips 13 sleeved on the multiple rotating rods 14 to rotate. This allows the cleaning strips 13 to clean the dust on the surface of the transparent cover 3. In addition, the auxiliary structure removes the dust from the cleaning surface, thus avoiding the situation where dust accumulates on the cleaning surface when there is too much dust on the surface of the transparent cover 3, which would reduce the cleaning effect of the cleaning strips 13.

[0035] like Figure 5 As shown, the drive structure includes a drive gear 18 disposed on the end of the rotating rod 14 located at the bottom of the cleaning crank 7, a rotating gear 19 disposed on the cleaning crank 7 and meshing with the drive gear 18, and a drive wheel 20 connected to the end of the rotating gear 19 via a connecting rod 21. The surface of the drive wheel 20 is perpendicularly attached to the side of the transparent cover 3. When the rotating ring 5 drives the cleaning crank 7 to rotate around the transparent cover 3, the drive wheel 20 rotates around the transparent cover 3.

[0036] In this embodiment, the end of the lowest rotating rod 14 among the multiple rotating rods 14 meshes with the rotating gear 19 on the driving wheel 20 through the driving gear 18. This allows the rotating rod 14 to rotate when the cleaning rod 7 rotates around the transparent cover 3, thus avoiding the need to add a new driving source to drive the cleaning strip 13 to rotate.

[0037] like Figure 5 As shown, the auxiliary structure includes an auxiliary rod 15 that is rotatably inserted through a through hole in the bottom wall of the cleaning tank 12, a cleaning brush disposed on the body of the auxiliary rod 15 and in contact with the cleaning surface, a cleaning gear 17 disposed on the end of the auxiliary rod 15, and a cleaning gear 17 disposed on the end of one of the rotating rods 14 and meshing with the auxiliary gear 16.

[0038] In this embodiment, when the cleaning strip 13 rotates, it drives the rotating rod 14 to rotate. One of the rotating rods 14 is equipped with an auxiliary gear 16, which meshes with the cleaning gear 17 on the auxiliary rod 15. This allows the auxiliary gear 16 to rotate synchronously, thereby driving the cleaning brush on the auxiliary rod 15 to clean the dust on the cleaning surface of the cleaning strip 13, thus improving the cleanliness of the cleaning strip 13 and enabling the cleaning strip 13 to continuously clean the transparent cover 3.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
