Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, in particular to a forklift with high safety. Background Art
[0002] Forklifts are industrial handling vehicles, referring to various wheeled transport vehicles used for loading, unloading, stacking, and short-distance transportation of palletized cargo. They are commonly used for transporting large objects in warehouses and are typically powered by either a fuel engine or a battery. Industrial handling vehicles are widely used in ports, train stations, airports, freight yards, factory floors, warehouses, distribution centers, and distribution centers. They handle loading, unloading, and transporting palletized cargo within ship cabins, train compartments, and containers, and are essential equipment for pallet and container transportation.
[0003] The operating environment of a forklift is relatively complex. When reversing, it is often necessary to take into account both the front and rear aspects to prevent hitting people while reversing. However, due to the obstruction of the forklift body, the operator's vision is blocked during reversing. Continuing to reverse when there are people behind is very likely to accidentally injure others. Even if the forklift is checked around before reversing, pedestrians will inevitably enter the forklift's reversing range. In order to prevent accidental injuries to others, reversing buzzers are often installed on forklifts to warn people to stay away from the forklift's operating range, thereby ensuring that the forklift does not accidentally injure others. However, forklifts often start to reverse suddenly. For elderly people with limited mobility, they react slowly and often have no time to dodge when the buzzer sounds, which can easily cause danger. In addition, the buzzer is often loud to warn people. During the operation of the forklift, it needs to move forward and backward continuously, and it is used frequently, which has a greater impact on the surrounding residents. Utility Model Content
[0004] The purpose of the utility model is to provide a forklift with high safety. The forklift with high safety is provided with a safety warning area. Not only is the range of the safety warning area adjustable, but it will not affect the operator's sight and will not affect the people living nearby due to excessive noise.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A forklift with high safety comprises a forklift body, the forklift body comprising a carport, warning lights are installed on the left side wall, right side wall and rear side wall of the carport top, the light projected by the warning lights is a straight-line projection warning line; the projection warning lines projected by three warning lights are combined into a three-frame projection warning area, and the forklift body is within the projection warning area.
[0007] Preferably, the projection warning area is adjustable.
[0008] Preferably, mounting holes are provided on both sides of the warning light, and a U-shaped hinge seat is connected to the forklift body. Both sides of the U-shaped hinge seat are bolted to the mounting holes. The warning light is rotated along the straight line where the two mounting holes are located as the rotating axis and the bolts are tightened after the rotation is completed to adjust the angle of the warning light and thus change the projected warning area.
[0009] Preferably, the U-shaped hinge seat is connected to the top side wall of the carport by bolts.
[0010] Preferably, the warning light includes a lamp housing, which is in an elongated strip shape, a lens portion is provided inside the lamp housing, a wiring harness integrated board is provided on the side of the lens portion away from the warning light, and an LED light source is provided on the wiring harness integrated board. The light emitted by the LED light source is reflected and refracted by the lens portion and projected onto the ground in a straight line.
[0011] Preferably, the lens portion is two ellipsoidal structures that are closely and symmetrically arranged along the first direction, and the LED light source is two rows of LED lamp beads arranged and symmetrically arranged along the first direction, and each row of LED lamp beads includes three LED lamp beads arranged along the first direction; the first direction is the length direction of the lamp housing.
[0012] Preferably, a radiator is further provided inside the lamp housing, and the radiator surrounds the bottom and four sides of the wire harness integrated board. A breathing hole is provided on the radiator, and the breathing hole is communicated with the lamp housing.
[0013] Preferably, a breathable cap is provided on the lamp housing, and the breathable cap is installed at the breathing hole behind the lamp housing; a sealing gasket is provided at the connection between the lens part and the radiator, and a lining frame is provided at the edge of the shell near the lens part, and the lining frame presses the lens part against the sealing gasket.
[0014] Preferably, a thermally conductive gasket is provided between the radiator and the wiring harness integrated board, and the thermally conductive gasket and the wiring harness integrated board are bolted together to ensure a tight fit between the wiring harness integrated board and the radiator.
[0015] Preferably, the wiring harness integrated board is connected to a plug, the plug is connected to a power source, and the power source is a forklift body battery or an external battery.
[0016] In the above technical solution, warning lights are installed on the left, right, and rear walls of the carport roof. These lights project a straight-line warning line, and the projected warning lines from the three warning lights combine to form a three-framed projected warning area. The projected warning area is located on the left, right, and rear sides of the forklift body, so it does not obstruct the driver's line of sight. The forklift body is within the projected warning area. During the use of the forklift body, the projected warning area serves as a warning to pedestrians, preventing them from accidentally entering the projected warning area. This further prevents injuries to pedestrians caused by the forklift body when turning or reversing due to operator negligence.
[0017] The projected warning area is adjusted by providing mounting holes on either side of the warning light, connecting a U-shaped hinged base in the middle of the carport's roof wall, and bolting each side of the U-shaped hinged base to the mounting holes. The warning light is then rotated along the line between the two mounting holes. Once adjusted to the desired angle, the angle between the warning light and the carport's roof wall is fixed by tightening the bolts. The projected warning area can be adjusted based on the forklift's speed or surrounding environment. When the forklift is traveling faster, the projected warning area is expanded; when the forklift is traveling slower, the projected warning area is reduced.
[0018] By providing a lens portion comprising two ellipsoidal surfaces arranged symmetrically and adjacent to each other along a first direction, light emitted by the LED light source is reflected and refracted by the ellipsoidal surfaces to produce a wide projected warning line. Each ellipsoidal surface corresponds to a row of LED beads, and each row includes three LED beads arranged along the length of the lamp housing. Furthermore, a lamp housing is provided above, below, to the left, to the right, and behind the wiring harness integrated board and the lens portion. The lamp housing is elongated and features a vent cap at the rear, providing waterproof protection while also balancing pressure inside and outside the lamp housing and preventing structural damage. By connecting a plug to the wiring harness integrated board and providing an external power supply to the forklift body, when the forklift body is not in use, connecting the plug to the external power supply powers the wiring harness integrated board, causing the LED beads to illuminate. Reflection and refraction from the lens portion produce a linear projected warning line, alerting nearby personnel that the forklift body is about to be used and reminding those within the projected warning area to leave.

DETAILED DESCRIPTION
[0026] The present invention will be further described below with reference to the accompanying drawings:
[0027] like Figures 1 to 6 As shown, a high-safety forklift includes a forklift body, which includes a carport 11. Warning lights 2 are installed in the middle of the left wall, right wall, and rear wall of the top of the carport 11. The warning lights 2 project a straight-line warning line 4, and the projected warning lines 4 projected by the three warning lights 2 are combined to form a three-framed projected warning area 41. The forklift body is within the projected warning area 41. When the forklift body is in use, the projected warning area 41 serves as a warning to pedestrians passing by, preventing them from accidentally entering the projected warning area 41. This further prevents the forklift body from causing harm to pedestrians when turning or reversing due to operator negligence.
[0028] The warning light 2 includes a lamp housing 21, which is made of die-cast aluminum. This not only dissipates heat from the lamp housing 21 but also strengthens the lamp housing 21, protecting internal components from damage and making the warning light 2 more stable and reliable. The lamp housing 21 is in the shape of an elongated strip, fixing the shape of the warning line to an elongated strip. A lens portion 22 is provided inside the lamp housing 21. The lens portion 22 is composed of two ellipsoidal structures arranged closely and symmetrically along the length of the lamp housing. A wiring harness integrated board 24 is provided on the side of the lens portion 22 away from the warning light 2. The wiring harness integrated board 24 is used to drive and support the LED light source. The LED light source is two rows of LED lamp beads 23 arranged symmetrically along the length of the lamp housing. Each row of LED lamp beads 23 includes three LED lamp beads 23 arranged along the length of the lamp housing. A breathing hole 241 is provided on the harness integrated board 24, and the breathing hole 241 is connected to the lamp housing 21, and a breathable cap 30 is provided at the place where the lamp housing 21 is connected to the breathing hole 241. The breathable cap 30 is composed of three parts: an outer shell, a rubber sleeve and a waterproof breathable membrane. The three work together to have the effect of being breathable and waterproof. After the warning light 2 is lit, the temperature in the inner cavity of the lamp housing 21 increases, the air expands, and the excess air is discharged from the breathable cap 30; after the warning light 2 is turned off, the temperature in the inner cavity of the lamp housing 21 decreases, the air contracts, and external air enters from the breathable cap 30, ensuring that the internal pressure of the lamp is consistent with the external pressure, and the internal parts of the lamp will not be damaged due to pressure problems.
[0029] Mounting holes 31 are provided on both sides of the warning light 2. A U-shaped hinge seat 29 is connected to the middle portion of the top side wall of the carport 11. The two sides of the U-shaped hinge seat 29 are bolted to the mounting holes 31, and the warning light 2 is rotated along the straight line where the two mounting holes 31 are located. After adjusting to the desired angle, the angle between the warning light 2 and the top side wall of the carport 11 is fixed by tightening the bolts, thereby completing the change of the projected warning area 41. The range of the projected warning area 41 of the three frames is adjustable. During use, the range of the projected warning area 41 can be adjusted according to the driving speed of the forklift body or the surrounding environment. When the forklift body is driving faster, the range of the projected warning area 41 is appropriately expanded. When the forklift body is driving slower, the range of the projected warning area 41 is appropriately reduced.
[0030] A heat sink 25 is located within the lamp housing 21. A breathing hole 241 extends through the heat sink 25 and connects to the lamp housing 21. The heat sink 25 surrounds the bottom and periphery of the wiring harness integrated board 24, dissipating heat from the LED lamp beads 23. This effectively reduces the temperature of the LED lamp beads 23, reduces light decay, and further extends the lamp's lifespan. A sealing gasket 26 is located at the junction between the lens 22 and the heat sink 25. Made of silicone, this gasket prevents water and dust from entering the interior of the warning light 2. A liner frame 27, made of die-cast aluminum, is located near the edge of the housing near the lens 22. This frame 27 dissipates heat from the lamp housing 21 while also enhancing its strength. The liner frame 27 presses the lens 22 against the gasket 26, providing a seal while maintaining the relative position of the LED lamp beads 23 and lens 22.
[0031] In this embodiment, the distance between the three projected warning lines 4 and the forklift body is 1.5-2 meters. A thermal pad 28 is provided between the radiator 25 and the wiring harness integrated board 24, and the wiring harness integrated board 24 and the thermal pad 28 are fixedly connected by bolts. The thermal pad 28 discharges the air between the wiring harness integrated board 24 and the radiator 25, so that the wiring harness integrated board 24 and the radiator 25 fit tightly together, thereby increasing the heat conduction effect of the radiator 25. The thermal pad 28 is made of graphite and conducts the heat of the LED lamp beads 23 to the radiator 25, ensuring that the ambient temperature of the LED lamp beads 23 is below 50 degrees, thereby increasing the life of the LED lamp beads 23, reducing light decay, and ensuring the quality of the warning light 2. The wiring harness integrated board 24 is connected to the external plug 5, and the plug 5 is connected to the battery of the forklift body 1.
[0032] In a preferred embodiment, sealant is filled between the wiring harness integrated board 24 and the heat sink 25 to fill the gap between the two, thereby increasing the connection relationship between the two and further improving the sealing between the two to prevent the intrusion of water or dust.
[0033] In a preferred embodiment, an external power supply is provided on the forklift body 1. When the forklift body 1 is not started, the external power supply can power the wiring harness integrated board 24, causing the LED lamp beads 23 to emit light, and generate a straight-line projection warning line 4 under the reflection and refraction of the lens portion 22, which is used to warn the surrounding personnel that the forklift body 1 is about to be used, and to remind the surrounding personnel in the projection warning area 41 to leave the projection warning area 41.
[0034] Before using the forklift body 1, first connect the plug 5 to the external power supply to control the warning light 2 to light up, and adjust the angle of the warning light 2 according to the speed of the forklift body 1 or the surrounding environment, thereby adjusting the size of the projected warning area 41. After the adjustment is completed, start the forklift body 1 to operate.
[0035] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
