Description

Technical Field

[0001] This utility model relates to the field of safety control technology for dump trucks, specifically a device for detecting the opening and closing status of the tailgate hook lock of a dump truck. Background Technology

[0002] The rear cargo box of a dump truck is typically secured to the side panels by hooks on both sides. During unloading, the hooks must be manually opened first, and then the lifting mechanism tilts the cargo box to unload. In current technology, the opening and closing of the hooks relies entirely on the driver's manual operation. If the lifting mechanism is activated before the hooks are opened due to negligence, fatigue, or omissions in the operating procedure, the following problems may occur: the cargo box cannot tilt properly for unloading, causing material to accumulate inside, resulting in an imbalance between the lifting force and the weight of the material; the cargo box cannot be unfolded due to the hooks, causing a sharp shift in the vehicle's center of gravity during lifting, which can easily lead to serious accidents such as rollovers or rear-end collisions (the front of the truck lifting off the ground); forced lifting can cause deformation of the hooks, lifting mechanism, or chassis, resulting in mechanical damage.

[0003] Currently, the industry mainly avoids risks through non-technical means such as "driver training" and "posting warning signs," but human error is still difficult to completely avoid.

[0004] Now, a novel device for detecting the opening and closing status of the tailgate hook lock of a dump truck is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting the opening and closing status of the hook lock in the rear cargo box of a dump truck, so as to solve the problem mentioned in the background art that it does not have the function of detecting the opening and closing status of the hook lock.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for detecting the opening and closing status of a dump truck's rear tailgate hook lock, comprising a first housing, a second housing, and a third housing. A first rechargeable lithium battery is fixedly connected to the left side inside the first housing. A first MCU microcontroller unit is fixedly connected to the middle position of the rear end inside the first housing. A tilt sensor is provided on the right side of the rear end inside the first housing. An infrared sensor receiver is fixedly connected to the right side of the first housing. An infrared sensor transmitter is fixedly connected to the left side of the second housing. A second rechargeable lithium battery is fixedly connected to the upper and lower ends of the right side of the second housing. A buzzer is fixedly connected to the bottom of the front end of the third housing. Two sets of warning lights are installed on the top of the front end of the third housing. A control button is provided at the middle position of the front end of the third housing. A second MCU microcontroller unit is fixedly connected to the rear end inside the third housing. A third rechargeable lithium battery is fixedly connected to the bottom end inside the third housing. Two sets of fixing magnets are fixedly connected to the rear end of the third housing.

[0007] As a further technical solution of this utility model, the right side of the infrared sensor receiving end penetrates through the right side of the first housing and extends to the outside, and the horizontal center lines of the infrared sensor receiving end and the infrared sensor emitting end coincide.

[0008] As a further technical solution of this utility model, the first housing is fixed to the outside of the rear tail box of the dump truck, and the second housing is fixed to the side of the hook.

[0009] As a further technical solution of this utility model, the first MCU microcontroller unit and the second MCU microcontroller unit are equipped with a wireless transmission module, and the first MCU microcontroller unit, the infrared sensor receiver, and the infrared sensor transmitter are electrically connected.

[0010] As a further technical solution of this utility model, the first housing and the tilt sensor are fixedly connected, and the first MCU microcontroller unit and the tilt sensor are electrically connected.

[0011] As a further technical solution of this utility model, the buzzer, the alarm light, and the second MCU microcontroller unit are electrically connected, the rear end of the third housing and the fixed magnet are flush, and the third housing is fixed in the cab of the dump truck.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the dump truck rear tail box hook lock opening and closing status detection device not only realizes the function of detecting the hook lock opening and closing status and the function of monitoring the tail box lifting status, but also realizes the function of facilitating early warning and reminder.

[0013] (1) By setting a first housing, a second housing, a third housing, a first rechargeable lithium battery, a first MCU microcontroller unit, an infrared sensor receiver, an infrared sensor transmitter, and a second rechargeable lithium battery, when the tail hook lock of the dump truck is locked, the infrared signal emitted by the infrared sensor transmitter on the second housing is continuously received by the infrared sensor receiver on the first housing, and the alarm light is green. When the tail hook lock of the dump truck is manually opened, the direction of the infrared sensor transmitter changes with the hook lock, and the infrared signal emitted by the infrared sensor transmitter cannot be received by the infrared sensor receiver on the first housing, and the alarm light is red. It can be intuitively judged whether the hook lock is open or not, and the function of detecting the opening and closing status of the hook lock is realized.

[0014] (2) By setting up an inclination sensor, when the dump truck bed is lifted by the hydraulic mechanism, the angle of the tail box will change. The inclination sensor can directly detect the angle of the tail box. Combined with the signals fed back from the infrared sensor receiver and the infrared sensor transmitter, if the angle of the tail box is greater than five degrees in the unlocked state, the buzzer and alarm light will sound an alarm simultaneously, and the lifting action of the hydraulic mechanism will be interrupted to avoid accidents such as vehicle rollover. This realizes the function of monitoring the lifting status of the tail box.

[0015] (3) By setting up a buzzer, warning light, control button, second MCU microcontroller unit, third rechargeable lithium battery and fixed magnet, when the hook lock is not opened and the tail box is lifted, the buzzer sounds and the warning light flashes continuously to remind the driver to pay attention in time. The fixed magnet makes it easy for the third housing to be attached to the A-pillar of the vehicle, making installation convenient and realizing the function of easy early warning reminder.

[0023] Example: Please refer to Figure 1-5 A device for detecting the opening and closing status of a dump truck's rear tailgate hook lock includes a first housing 1, a second housing 2, and a third housing 3. A first rechargeable lithium battery 4 is fixedly connected to the left side inside the first housing 1. A first MCU microcontroller unit 5 is fixedly connected to the middle position of the rear end inside the first housing 1. An tilt sensor 9 is provided on the right side of the rear end inside the first housing 1. An infrared sensor receiver 6 is fixedly connected to the right side of the first housing 1. An infrared sensor transmitter 7 is fixedly connected to the left side of the second housing 2. A second rechargeable lithium battery 8 is fixedly connected to the upper and lower ends of the right side of the second housing 2. A buzzer 10 is fixedly connected to the bottom of the front end of the third housing 3. Two sets of alarm lights 11 are installed on the top of the front end of the third housing 3. A control button 12 is provided at the middle position of the front end of the third housing 3. A second MCU microcontroller unit 13 is fixedly connected to the rear end inside the third housing 3. A third rechargeable lithium battery 14 is fixedly connected to the bottom end inside the third housing 3. Two sets of fixing magnets 15 are fixedly connected to the rear end of the third housing 3.

[0024] The right side of the infrared sensor receiver 6 extends through the right side of the first housing 1 and to the outside. The horizontal center lines of the infrared sensor receiver 6 and the infrared sensor transmitter 7 coincide. The first housing 1 is fixed to the outside of the tail box of the dump truck. The second housing 2 is fixed to the side of the hook. The first MCU microcontroller unit 5 and the second MCU microcontroller unit 13 are equipped with a wireless transmission module. The first MCU microcontroller unit 5, the infrared sensor receiver 6, and the infrared sensor transmitter 7 are electrically connected to facilitate the detection of the opening and closing status of the hook lock.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the tailgate hook lock of the dump truck is engaged, the infrared signal emitted by the infrared sensor transmitter 7 on the second housing 2 is continuously received by the infrared sensor receiver 6 on the first housing 1, and the warning light 11 is green. When the tailgate hook lock of the dump truck is manually opened, the direction of the infrared sensor transmitter 7 changes with the hook lock, and the infrared signal emitted by the infrared sensor transmitter 7 cannot be received by the infrared sensor receiver 6 on the first housing 1, and the warning light 11 is red. This allows for a direct visual judgment of whether the hook lock is open.

[0026] The first housing 1 and the tilt sensor 9 are fixedly connected, and the first MCU microcontroller unit 5 and the tilt sensor 9 are electrically connected to facilitate the detection of the tilt angle of the tail box;

[0027] Specifically, such as Figure 1 and Figure 3As shown, the angle of the trunk will change. The tilt sensor 9 can directly detect the angle of the trunk. Combined with the signals fed back by the infrared sensor receiver 6 and the infrared sensor transmitter 7, if the angle of the trunk is greater than five degrees when the trunk is not unlocked, the buzzer 10 and the warning light 11 will sound an alarm simultaneously, and the lifting action of the hydraulic mechanism will be interrupted to avoid accidents such as vehicle rollover.

[0028] The buzzer 10, the alarm light 11, and the second MCU microcontroller unit 13 are electrically connected. The rear end of the third housing 3 and the fixing magnet 15 are flush. The third housing 3 is fixed in the cab of the dump truck to facilitate status feedback and alarm issuance.

[0029] Specifically, such as Figure 1 and Figure 5 As shown, when the hook lock is detected to be not open and the tail box is lifted, the buzzer 10 sounds and the warning light 11 flashes continuously to remind the driver to pay attention in time. The fixing magnet 15 makes it easy for the third housing 3 to be attached to the A-pillar of the vehicle, making installation convenient.

[0030] Working Principle: In use, when the tailgate hook lock of the dump truck is engaged, the infrared signal emitted by the infrared sensor transmitter 7 on the second housing 2 is continuously received by the infrared sensor receiver 6 on the first housing 1, and the warning light 11 is green. When the tailgate hook lock is manually opened, the direction of the infrared sensor transmitter 7 changes with the hook lock, and the infrared signal emitted by the infrared sensor transmitter 7 cannot be received by the infrared sensor receiver 6 on the first housing 1, turning the warning light 11 red. This allows for a direct visual assessment of whether the hook lock is open. The angle of the tailgate will change, and the tilt sensor 9 can directly detect the angle of the tailgate. Combined with the signals from the infrared sensor receiver 6 and the infrared sensor transmitter 7, if the tailgate angle is greater than five degrees when the truck is not unlocked, the buzzer 10 and the warning light 11 will simultaneously sound an alarm, while also interrupting the lifting action of the hydraulic mechanism to prevent accidents such as vehicle rollover. When the hook lock is detected to be locked and the tailgate is lifted, the buzzer 10 sounds and the warning light 11 flashes continuously to remind the driver to pay attention. The fixing magnet 15 makes it easy for the third housing 3 to be attached to the A-pillar of the vehicle.
