Description

Technical Field

[0001] The present invention relates to the technical field of forklift driving monitoring, and in particular to a forklift safe driving visual control system and a forklift. Background Art

[0002] As a handling tool, forklifts greatly facilitate the movement and transportation of goods and materials. Today's forklifts mainly include a body and a gantry mechanism arranged in front of the body. The gantry mechanism is used to fork and lift goods, and the body travels and transports the goods to a designated location.

[0003] However, when the gantry mechanism of a forklift carries more cargo or higher cargo, it will block the driver's field of vision. The driver cannot see the situation in front of the forklift while driving the forklift forward. When an emergency occurs, the driver cannot take timely measures, which is prone to safety accidents.

[0004] Therefore, in order to improve the safety of forklifts in the process of transporting goods, it is necessary to improve and optimize the existing forklift structure so that the driver can maintain a good field of vision, understand the situation in front of the forklift in time and take corresponding measures to ensure driving safety. Therefore, it is necessary to propose a more reasonable technical solution to solve the deficiencies in the existing technology. Summary of the invention

[0005] In order to solve the defects of the prior art mentioned in the above content, the present invention provides a forklift safe travel visual control system and a forklift. By improving the gantry mechanism of the forklift, the visual control system on the gantry mechanism obtains the field of view in front of the forklift for the driver to view during driving and take corresponding driving measures in time according to the obtained field of view information.

[0006] In order to achieve the above object, the technical solution specifically adopted by the present invention is:

[0007] A forklift safe travel visual control system includes a camera assembly arranged on a forklift door frame mechanism and a display assembly arranged on the vehicle body; the camera assembly includes at least two groups of cameras with adjustable longitudinal height position and lateral width position, and the camera includes a camera that can rotate within a range of 360°; the display assembly includes a touch display and a central control machine, and the camera assembly and the touch screen are both connected to the central control machine.

[0008] The above-mentioned visual control system obtains the field of view in front of the forklift through the camera component and transmits the obtained signal to the central control machine. The central control machine displays it through the touch display after processing, which makes it convenient for the driver to obtain the field of view in front in real time during driving and improves driving safety.

[0009] In the present invention, the camera is set to be 360° adjustable, which is convenient for the driver to control through the touch display. The shooting angle of the camera can be adjusted to obtain a more suitable field of view; the angle of the camera can also be adjusted to obtain the field of view in front and behind the vehicle at the same time, thereby improving the driving safety of the driver.

[0010] Furthermore, the camera assembly used in the present invention can adjust the shooting angle, and the adjustment can be achieved through a variety of feasible structures. The specific structure is not limited to the only one. Here, it is optimized and one of the feasible options is cited: the camera assembly includes an adjustment bracket connected to the gantry mechanism, the adjustment bracket includes a connection base, a first connecting arm horizontally fixed to the connection base, a second connecting arm is hinged on the first connecting arm and the second connecting arm rotates in the longitudinal direction, and a camera seat is arranged on the second connecting arm. The camera is arranged at the camera seat and moves with the camera seat. When such a scheme is adopted, the first connecting arm is horizontally fixed and extends toward both sides of the vehicle body. One end of the first connecting arm is connected to the connection base, and the other end is connected to the second connecting arm. When the second connecting arm rotates inward, the camera base and the camera are close to the vehicle body. When the second connecting arm rotates outward, the camera base and the camera are away from the vehicle body. When the second connecting arm rotates outward to a horizontal position, the maximum outward angle is reached, and the shooting angle of the camera here is the largest.

[0011] Furthermore, when adjusting the position of the camera, keeping the camera level is the key to ensuring the display effect of the touch display. Here, an optimized setting is made and one feasible option is given: the camera seat is hinged to the second connecting arm. When such a solution is adopted, no matter how the second connecting arm rotates, the camera seat can be adjusted to a horizontal level, so that the camera shooting picture is a horizontal picture, which is convenient for the driver to observe.

[0012] Furthermore, due to the use of an articulated connection structure, in order to facilitate the adjustment of the angle, an optimization is performed here: damping is provided at the articulation between the first connecting arm and the second connecting arm and at the articulation between the second connecting arm and the camera seat. Such a solution can help maintain the angle of the second connecting arm and the angle of the camera seat.

[0013] Furthermore, when the camera rotates 360°, in order to achieve better angle adjustment, an optimization is made here and one feasible option is given: the camera includes a base and a head, the base is provided with a spherical groove, the head is spherical and rotates with the spherical groove. When such a solution is adopted, the camera can rotate within a horizontal range of 360° and can also be adjusted in pitch.

[0014] Furthermore, the display assembly is used to display the front view of the vehicle body, and the height can be adjusted accordingly according to the needs of the driver in the vehicle. Specifically, an optimization is made here and one feasible option is given: the display assembly includes a vertical rod set on the vehicle body, and the touch display is set on the vertical rod and slides and rises along the vertical rod. When such a solution is adopted, the touch display can be raised to facilitate the driver's viewing and avoid excessive head movements; at the same time, the touch display can be lowered when it is not necessary to view it to avoid affecting the driver's field of view.

[0015] Furthermore, there are various solutions for adjusting the height of the touch display, which are not limited to the only one. Here, we optimize and give one feasible option: the touch display is provided with a connector, the connector is slidably sleeved with the vertical rod, and the connector is also provided with a locking member, which presses the connector and the vertical rod to fix or adjust the looseness. When such a solution is adopted, a clamp structure, a threaded pressing structure, a clamping structure, a pin structure, etc. can be provided as the locking structure of the locking member.

[0016] Furthermore, the setting position of the central control machine is optimized, and one feasible option is given here: the central control machine is integrated on the touch display.

[0017] Furthermore, in order to avoid cluttered lines, the vertical rod is optimized and improved, and the following feasible option is given: the vertical rod is hollow inside, and signal lines and conductive lines are arranged inside the vertical rod and connected to the touch display.

[0018] The above content discloses a visual control system, and the present invention also discloses a forklift equipped with the visual control system described in the above content. When the forklift is used for handling work, turning on the visual control system can assist the driver to observe the environment ahead, thereby improving safety.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The visual control system and forklift disclosed in the present invention can help the driver obtain the field of view in front of the forklift through the cooperation of the camera component and the display component, thereby improving driving safety, reducing the occurrence of accidents, and making the forklift handling process more standardized.

[0037] Preferably, in this embodiment, two groups of cameras are provided, which are respectively provided on the left and right sides of the gantry mechanism 2, and the two groups of cameras can simultaneously obtain the field of view in front of the forklift, and can also adjust the angle to obtain the field of view in front of the forklift or behind the forklift respectively.

[0038] The above-disclosed visual control system obtains the field of view in front of the forklift through the camera component 3, and transmits the obtained signal to the central control computer 403. The central control computer 403 processes and displays it through the touch display 402, so that the driver can obtain the field of view in front in real time during driving, thereby improving driving safety.

The shooting angle of the camera can be adjusted to obtain a more suitable field of view; the angle of the camera can also be adjusted to obtain the field of view in front and behind the vehicle body 1 at the same time, thereby improving the driving safety of the driver.

[0041] Preferably, the camera assembly 3 used in this embodiment can adjust the shooting angle, and the adjustment can be achieved through a variety of feasible structures. The specific structure is not limited to the only one. This embodiment is optimized and adopts one of the feasible options: Figure 5 , Figure 6 , Figure 7As shown, the camera assembly 3 includes an adjustment bracket connected to the gantry mechanism 2, the adjustment bracket includes a connection base 301, a first connection arm 302 horizontally fixed to the connection base 301, a second connection arm 303 is hinged on the first connection arm 302 and the second connection arm 303 rotates in the longitudinal direction, a camera seat 304 is arranged on the second connection arm 303, and the camera is arranged at the camera seat 304 and moves with the camera seat 304. When such a scheme is adopted, the first connection arm 302 is horizontally fixed and extends toward both sides of the vehicle body 1, one end of the first connection arm 302 is connected to the connection base 301, and the other end is connected to the second connection arm 303, when the second connection arm 303 rotates inward, the camera base 305 and the camera are close to the vehicle body 1, when the second connection arm 303 rotates outward, the camera base 305 and the camera are away from the vehicle body 1, and when the second connection arm 303 rotates outward to a horizontal position, the maximum abduction angle is reached, and the shooting angle of the camera is the largest here.
