Description

Technical Field

[0001] This application relates to the field of lighting technology, and more specifically, to a lighting system for a forklift. Background Technology

[0002] In modern material handling and warehousing, forklifts are crucial equipment, widely used for loading, unloading, stacking, and transporting goods. However, in low-light conditions, the lighting systems of traditional forklifts reveal significant shortcomings. The headlights have a fixed angle and illumination range, unable to dynamically adjust according to the height of the forks. When the forks are raised high or operating in confined spaces, the fixed headlight angle restricts the operator's field of vision, creating blind spots and increasing operational difficulty and safety risks. To improve visibility, drivers may need to frequently adjust the forklift position or their own posture, which not only affects work efficiency but may also create safety hazards.

[0003] In addition, in order to maintain sufficient lighting, headlights are usually kept on continuously, consuming electricity even when not needed, resulting in energy waste. Utility Model Content

[0024] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] This application provides a lighting system for a forklift, in which an adjustment knob controls the corresponding LED lights on the headlights to illuminate the forklift working area synchronously, thereby reducing the risk of goods falling under poor lighting conditions and improving operational safety.

[0029] like Figure 1 As shown, the lighting system of the forklift provided in this application includes an adjustment knob 3 and a headlight 1. The adjustment knob 3 has an adjustable resistor, with different resistance values ​​corresponding to different fork heights. When the adjustment knob 3 is rotated synchronously with the lifting and lowering of the forks, the resistance value connected to the circuit changes, thereby achieving different voltage outputs.

[0030] Preferably, the adjustment knob 3 is installed on the lifting valve rod of the forklift so that the driver can conveniently adjust the illumination height of the light while operating the forks to lift or lower, that is, to make the light follow the movement of the goods.

[0031] like Figure 1 As shown, preferably, the lighting system also includes a light switch 2, which is electrically connected to the output terminal of the power supply, the input terminal of the adjustment knob 3, and the input terminal of the headlight 1, respectively, to control the on / off state of the power supply, thereby controlling the working state of the adjustment knob 3 and the headlight 1. The light switch 2 can control the power supply of the entire lighting system, and can cut off the light power supply when not in use, saving energy.

[0032] Preferably, the light switch 2 is installed on the dashboard of the forklift, which controls the power supply and cut-off of the whole vehicle without changing the original layout and reduces the number of changes in the original forklift layout.

[0033] like Figure 1 As shown, the headlight 1 is mounted on the front outrigger of the forklift overhead guard to prevent the headlight 1 from being blocked above and below, thus affecting the illumination range.

[0034] like Figure 2 and 4 As shown, the headlight 1 is equipped with multiple rows of LED lights 12, and the headlight 1 is equipped with a circuit board 11. The circuit board 11 controls the lighting or turning off of each row of LED lights according to the rotation angle of the adjustment knob 3, so that the light follows the movement of the fork better, the illumination area is more accurate and brighter, and the following effect is better.

[0035] Preferably, such as Figure 3As shown, multiple rows of LED lights 12 are distributed on the arc-shaped surface, with each LED light illuminating the normal line of the arc surface. This arrangement ensures that the illumination range is as large as possible, thereby meeting different lifting height requirements.

[0036] like Figure 2 As shown, the circuit board 11 includes an AD acquisition circuit 111, a microcontroller 112, and MOSFETs 113 with the same number of rows as the LEDs. The input terminal of the AD acquisition circuit 111 is connected to the output terminal of the adjustment knob 3, the input pin of the microcontroller 112 is connected to the output terminal of the AD acquisition circuit 111, the input terminal of each MOSFET 113 is connected to one output pin of the microcontroller 112, and the output terminal of each MOSFET 113 is connected to a row of LEDs in the headlight 1.

[0037] Based on the above, preferably, the adjustment knob 3 is equipped with a self-reset switch. When the adjustment knob is pressed, the output voltage of the adjustment knob is 0V, at which time the circuit board controls all rows of LED lights to light up, realizing temporary emergency lighting. When the adjustment knob 3 is stopped being pressed, the self-reset switch drives the adjustment knob 3 to automatically spring back. When the adjustment knob 3 is lifted, the circuit board 11 controls the corresponding row of LED lights to light up according to the rotation angle of the adjustment knob 3.

[0038] Specifically, when the adjustment knob 3 is in the pop-up state, the AD acquisition circuit 111 transmits the detected output voltage of the adjustment knob 3 to the microcontroller 112. The microcontroller 112 determines which MOS transistor 113 to input the signal based on the voltage, thereby controlling the row of LEDs at the position corresponding to the MOS transistor 113 to work, so that the position of the light illumination can be adjusted with the movement of the fork.

[0039] In this application, while the driver operates the valve lever with one hand, he can simultaneously rotate the adjustment knob to adjust the lighting angle, so that the lighting area moves with the forks, reducing the risk of goods falling under poor lighting conditions and improving operational safety.

[0040] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
