Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in FIG. 1, a forklift safety device may include four infrared sensing sensors S1-S4, a circuit board, and a warning device. The infrared ray sensor S1-S4 is installed at four positions of the front, back, left and right of the forklift and is used for detecting whether people or animals exist within a preset distance. It should be understood that the infrared sensor may be installed only at the front-rear position or the left-right position of the forklift. The circuit board is electrically connected with the infrared sensor S1-S4 and the warning device and is used for driving the warning device to send out an active safety prompting signal according to the received detection signal of the infrared sensor S1-S4 so as to prompt a driver to actively decelerate or stop, thereby ensuring safe driving. Specifically, the circuit board comprises a control module U1 and peripheral components (not shown) thereof, the warning device comprises a loudspeaker Spk1 and four warning lamps L1-L4, the warning lamps L1-L4 and infrared sensing sensors S1-S4 are in one-to-one correspondence and are close to each other, a signal input end of the control module U1 is connected with output ends of the infrared sensing sensors S1-S4, and the control module U1 drives the loudspeaker Spk1 and the four warning lamps L1-L4 according to received signals of the infrared sensing sensors S1-S4. For example, when the front infrared sensor S1 detects a person, the control module drives the speaker Spk1 to emit a warning sound such as "person in front, please notice" or "person in front, please slow down" to remind the driver, and the front warning light L1 flashes to attract the attention of passersby; when the rear infrared sensor S4 detects a person, the control module drives the speaker Spk1 to emit a warning sound such as "a person is behind, please notice" or "a person is behind, please slow down" to remind the driver, and the rear warning light L4 flashes to attract the attention of passersby; and so on. The utility model discloses an initiative safety prompt reminds the driver to take corresponding safeguard measure (slow down or park), can avoid the emergence of incident. It should be understood that the warning lights L1-L4 may be omitted, or the lights of the forklift itself may be used as the warning lights.

Preferably, the infrared sensor S1-S4 is mounted on the forklift overhead guard. In this case, since the height of the overhead guard is higher than that of the person, the infrared ray sensor is inclined downward by a predetermined angle in order to ensure that the object can be detected. Preferably, the predetermined angle is 30 to 60 degrees. More preferably, the predetermined angle is 45 degrees.

Preferably, the infrared sensor S1-S4 is an infrared sensor with a wavelength range of 8-20 μm.

Preferably, the speaker Spk1 is installed near the driver's seat to ensure that the driver can hear the warning sound even when the ambient noise is relatively large, so that the driver can decelerate or stop the vehicle in time to achieve the purpose of safe driving.

In addition, in order to further improve the safety, the circuit board is electrically connected with a control unit of the forklift so as to send a deceleration signal to the control unit when the infrared sensing sensors S1-S4 detect the presence of a person or animal, so that the forklift is automatically decelerated, and the driving safety is ensured. It should be understood that the control unit determines whether to decelerate based on the actual vehicle speed when the deceleration signal is received, and may not decelerate if the speed is otherwise slow (e.g., less than 5 km/h).

In order to ensure the safety of the forklift, the predetermined distance is set to at least 2 meters, i.e. the warning device is actuated as long as a person or an animal is detected within 2 meters. The predetermined distance may be fixed or may be adjusted according to the actual vehicle speed, for example, if the forklift is running fast, the predetermined distance is long, and if the forklift is running slow, the predetermined distance is short.

Preferably, the circuit board is mounted in an electrical cabinet (not shown) mounted on the forklift. Of course, the circuit board can also be installed in the original control box of the forklift.

In addition, the power supply of the infrared sensing sensors S1-S4, the circuit board and the warning device can be a separate battery or a power supply system from a forklift.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
