Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety prevention and control, and in particular to a sensing and identification device for a transport vehicle. Background Art

[0002] Aluminum processing companies utilize a variety of transfer vehicles, including forklifts, shovels, aluminum water trucks, and charging trucks. Vehicle safety, employee safety, and road safety are crucial components of the production process. Transfer vehicles inevitably have blind spots while in motion. Forklifts, for example, are large and have high-positioned cabs. These blind spots increase when reversing, significantly impacting operator efficiency and endangering the safety of both the operator and others. Accidents can result in serious injuries or even fatalities.

[0003] Due to the existence of vehicle blind spots, some existing technologies use reversing radar for monitoring, which can predict people and obstacles, but the warning target is vague and inaccurate, and due to factors such as the complex vehicle operating environment, the variety of equipment, and the high mobility of employees, the driver may make misjudgments.

[0004] Some also use reversing images to deal with blind spots. Drivers rely on the images on the display screen and may easily ignore the situation in other locations. At the same time, the reversing image is fixed and it is difficult to increase the monitoring range by swinging. If all-round monitoring is to be achieved, reversing images must be installed in different positions of the vehicle, and the modification cost is high. Summary of the Invention

[0005] In order to solve the problem that existing blind spot monitoring facilities are difficult to specifically identify human figures and have a limited monitoring range, the utility model provides a transfer vehicle sensing and recognition device. By adding a human figure recognition sensor to the transfer vehicle, human figures can be specifically identified to avoid vehicle-related harm to personnel as much as possible. At the same time, the posture of the human figure recognition sensor is flexibly adjustable, and it can not only be installed on different types of transfer vehicles, but also increase the monitoring range.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0007] A transfer vehicle sensing and identification device is used to monitor people in the blind spots of transfer vehicles, including a mounting bracket and a human recognition sensor. The mounting bracket includes a horizontally rotatable mounting base and a telescopic rod that can be pitched and swung. At least one telescopic rod is provided above the mounting base, and the human recognition sensor is provided at the top of the telescopic rod to facilitate flexible adjustment of the horizontal angle, pitch angle and height of the human recognition sensor.

[0008] The mounting base includes a mounting cylinder, a mounting shaft controlled by a driving motor, and a mounting disk. The upper end of the mounting cylinder is open, facilitating the loading of components. The mounting shaft is rotatably arranged inside the mounting cylinder, and the top end of the mounting shaft is detachably connected to the mounting disk, facilitating the rotation of the mounting disk together. The mounting disk is located at the opening of the mounting cylinder, playing a certain blocking role. An articulated seat is detachably arranged on the mounting disk. The mounting disk is articulated to the telescopic rod through the articulated seat, facilitating the pitching swing of the telescopic rod. A locking component for controlling the pitching angle of the telescopic rod is also arranged between the articulated seat and the telescopic rod, facilitating the control of the swing of the telescopic rod.

[0009] Further, the mounting cylinder is a cylindrical body with an open upper end. A flange is provided at the lower end of the mounting cylinder. The mounting cylinder is detachably connected to the transfer vehicle through the flange, facilitating the arrangement of the mounting cylinder at different positions on the transfer vehicle.

[0010] Further, a limiting cylinder ring with a "ㄇ" - shaped cross - section is formed by the inward depression at the center of the bottom of the mounting cylinder. A first bearing is arranged inside the limiting cylinder ring. The cross - section of the mounting shaft is "丄" - shaped. The lower end of the mounting shaft extends into the limiting cylinder ring and is rotationally connected to the limiting cylinder ring through the first bearing, improving the smooth rotation of the mounting shaft.

[0011] Further, an auxiliary friction wheel is arranged on the mounting shaft. A compression spring is sleeved on the mounting shaft between the auxiliary friction wheel and the limiting cylinder ring. The compression spring abuts between the auxiliary friction wheel and the limiting cylinder ring, preventing the mounting shaft from rotating easily.

[0012] At least one driving motor is arranged inside the mounting cylinder. The mounting shaft and the driving motor are arranged side by side. A main friction wheel is arranged on the output shaft of the driving motor. The main friction wheel is in frictional contact with the auxiliary friction wheel. The transmission between the driving motor and the mounting shaft is realized by means of frictional contact, avoiding the jerks in the transmission.

[0013] Further, the mounting disk is sleeved on the top end of the mounting shaft and is connected to the mounting shaft by screws, facilitating the disassembly and assembly of the mounting disk. A limiting ring is arranged inside the mounting cylinder, and a second bearing is also arranged inside the mounting cylinder. The second bearing abuts against the limiting ring. The mounting disk is sleeved inside the second bearing and is rotationally connected to the mounting cylinder through the second bearing, improving the smoothness of the rotation of the mounting disk. <统一格式,将

[0015] Further, extension plates are arranged on both sides of the bottom end of the telescopic rod, and the extension plates extend into the articulated plate.

[0016] The locking assembly includes a locking shaft and nuts arranged at both ends of the locking shaft. The locking shaft is a threaded shaft. The locking shaft is passed between the extension plate and the hinge plate. The nuts at both ends squeeze the extension plate and the hinge plate inward at the same time, thereby facilitating the fixing of the pitch angle of the telescopic rod.

[0017] Through the above technical solution, the beneficial effects of the utility model are:

[0018] The utility model has a reasonable structural design, and the mounting seat has a horizontal rotation function. The driving motor can conveniently drive the mounting shaft and the mounting plate to rotate back and forth. An articulated seat is arranged above the mounting plate. The position of the articulated seat is adjustable and the number can be changed according to actual conditions. The mounting plate is hinged to a telescopic rod through the articulated seat, so that the telescopic rod can be conveniently pitched and swung. The telescopic rod itself can be adjusted in height, and a human figure recognition sensor is provided on the top of the telescopic rod. In this way, the horizontal angle and pitch angle of the human figure recognition sensor are adjustable, and the height can also be adjusted, so that the posture of the human figure recognition sensor can be flexibly adjusted, which not only increases the monitoring range, but also can be adapted to be installed on different types of transport vehicles. The scope of application is increased, which can ensure road safety and vehicle safety, as well as the personal safety of employees. The human figure recognition sensor can specifically monitor whether there are people within a certain blind spot range, effectively protect workers, and effectively prevent vehicles from accidentally colliding with people.

Specific Embodiment

[0026] The following will describe in detail the specific embodiment of the present utility model in conjunction with the drawings:

[0027] As Figures 1 to 6 shown, a transfer vehicle induction recognition device for monitoring personnel in the blind area of a transfer vehicle includes a mounting bracket and a human form recognition sensor 1. The human form recognition sensor 1 is arranged on the mounting bracket, and the human form recognition sensor 1 is used to specifically identify personnel to avoid harm to personnel when the vehicle is driving. The mounting bracket has the characteristics of horizontal rotation, pitching swing and height adjustment, which can flexibly change the posture of the human form recognition sensor 1 and enable the human form recognition sensor 1 to better adapt to the installation of different transfer vehicles.

[0028] The mounting bracket includes a rotatable mounting base 2 in the horizontal direction and a telescopic rod 3 that can pitch and swing, as Figure 1 shown. At least one telescopic rod 3 is arranged above the mounting base 2. The mounting base 2 can drive the telescopic rod 3 to swing horizontally, and the telescopic rod 3 can be adjusted in pitch relative to the mounting base 2. At the same time, the telescopic rod 3 itself can be adjusted in length. The human form recognition sensor 1 is arranged at the top end of the telescopic rod 3.

[0029] In this embodiment, the mounting base 2 includes a mounting cylinder 21, a mounting shaft 23 controlled by a driving motor 22 and a mounting disc 24. The mounting cylinder 21 is a cylindrical body with an open upper end. A flange 4 is arranged at the lower end of the mounting cylinder 21. The mounting cylinder 21 is detachably connected to the transfer vehicle through the flange 4, so as to realize the installation of the mounting base 2 and the transfer vehicle.

[0030] The mounting shaft 23 is rotatably arranged in the mounting cylinder 21. The mounting shaft 23 is a cylinder with a cross-section in the shape of "丄" and is located at the central position in the mounting cylinder 21. During installation, a limiting cylinder ring 5 with a cross-section in the shape of "ㄇ" is recessed inward at the center of the bottom of the mounting cylinder 21. A bearing I 6 is arranged in the limiting cylinder ring 5. The lower end of the mounting shaft 23 extends into the limiting cylinder ring 5 and is rotatably connected to the limiting cylinder ring 5 through the bearing I 6, thereby realizing the rotational installation of the mounting shaft 23 and the mounting cylinder 21, as Figure 2 and Figure 4 shown.

[0031] To drive the rotatable mounting shaft 23, an auxiliary friction wheel 7 is mounted on the mounting shaft 23. Rotation of the auxiliary friction wheel 7 drives the mounting shaft 23, and a friction ring 8 is attached to the outer circumference of the auxiliary friction wheel 7. Furthermore, at least one drive motor 22 is positioned within the mounting barrel 21. The mounting shaft 23 and the drive motor 22 are arranged side by side. A primary friction wheel 9 is mounted on the output shaft of the drive motor 22. The primary friction wheel 9 also has a friction ring 8 attached to its outer circumference. The friction ring 8 is a ring made of a material with a high friction coefficient, creating frictional contact between the primary friction wheel 9 and the auxiliary friction wheel 7.

[0032] When there is only one drive motor 22, by controlling the forward and reverse rotation of the drive motor 22, the mounting shaft 23 can be driven to reciprocate forward and reverse under the friction contact between the primary friction wheel 9 and the auxiliary friction wheel 7. The friction contact method reduces the sense of jerkiness when the mounting shaft 23 rotates forward and reverse and reverses.

[0033] In this embodiment, there are two drive motors 22, which are distributed on both sides of the mounting shaft 23. In this case, the main friction wheel 9 on the drive motor 22 has a friction ring 8 on only half of its circumference. Figure 3 As shown, the two main friction wheels 9 are controlled to move synchronously in opposite directions, and the friction rings 8 on the two main friction wheels 9 and the friction rings 8 on the auxiliary friction wheel 7 are controlled to stagger their contact. That is, when one main friction wheel 9 contacts the auxiliary friction wheel 7 to make it rotate, the other main friction wheel 9 is in an idling state. In this way, the two drive motors 22 can drive the installation shaft 23 to reciprocate forward and reverse. In other words, one drive motor 22 drives the installation shaft 23 to rotate forward, while the other drive motor 22 drives the installation shaft 23 to rotate counterclockwise.

[0034] To prevent the installation shaft 23 from rotating easily, a compression spring 10 is provided on the outer sleeve of the installation shaft 23 between the auxiliary friction wheel 7 and the limiting cylindrical ring 5. The compression spring 10 is tightly pressed between the auxiliary friction wheel 7 and the limiting cylindrical ring 5. Under the pushing action of the compression spring 10, an axial force is applied to the installation shaft 23, which not only prevents the installation shaft 23 from moving axially, but also increases the resistance to the rotation of the installation shaft 23, preventing the installation shaft 23 from rotating easily.

[0035] The top of the mounting shaft 23 is removably connected to a mounting disc 24, which is located at the opening of the mounting tube 21. The mounting shaft 23 drives the mounting disc 24 in rotation. The mounting disc 24 is a circular disk that fits over the top of the mounting shaft 23. The top of the mounting shaft 23 is prismatic, allowing for power transmission, allowing the mounting disc 24 to rotate. To ensure secure installation, the mounting disc 24 and the mounting shaft 23 are connected by screws to prevent them from falling off.

[0036] To ensure the smooth rotation of the mounting disc 24, a limiting ring 11 is provided inside the mounting cylinder 21. A second bearing 12 is also provided inside the mounting cylinder 21. The second bearing 12 is a plain bearing and is used to bear radial loads. The second bearing 12 abuts against the limiting ring 11, and the mounting disc 24 is sleeved inside the second bearing 12 and is rotationally connected to the mounting cylinder 21 through the second bearing 12.

[0037] A hinge seat 13 is detachably arranged on the mounting disc 24. The mounting disc 24 is hinged to the telescopic rod 3 through the hinge seat 13, as Figure 5 and Figure 6 shown. When the hinge seat 13 is installed, a plurality of mounting screw holes 14 are circumferentially and evenly provided on the mounting disc 24, and the hinge seat 13 is arranged in any one of the mounting screw holes 14. Specifically, the hinge seat 13 includes a hinge plate 131 with a "U" - shaped cross - section and a threaded column 132 provided below the hinge plate 131. The threaded column 132 is threadedly connected to the mounting screw hole 14. In this way, a plurality of hinge seats 13 can be threadedly connected to the mounting disc 24, and the installation positions of the hinge seats 13 are also selectable.

[0038] When the telescopic rod 3 is installed, the hinge plate 131 is hinged to the telescopic rod 3. Specifically, extension plates 15 are provided on both sides of the bottom end of the telescopic rod 3, and the extension plates 15 extend into the hinge plate 131. A locking component 16 for controlling the pitching angle of the telescopic rod 3 is also provided between the hinge seat 13 and the telescopic rod 3. The locking component 16 includes a locking shaft 161 and nuts 162 provided at both ends of the locking shaft 161. The locking shaft 161 is a threaded shaft. The locking shaft 161 passes through between the extension plate 15 and the hinge plate 131, so that the telescopic rod 3 and the hinge seat 13 can rotate. When the telescopic rod 3 needs to be fixed at a certain angle, the nuts 162 at both ends simultaneously squeeze the extension plate 15 and the hinge plate 131 inward. The nuts 162 are wing nuts. After the nuts 162 are tightened, they clamp the extension plate 15 and the hinge plate 131, and the pitching angle of the telescopic rod 3 is fixed by relying on the frictional force. At this time, the telescopic rod 3 cannot swing anymore. If the telescopic rod 3 needs to swing again, just loosen the nuts 162.

[0039] To ensure the stability of the telescopic rod 3, external gear rings 17 are symmetrically sleeved on both ends of the locking shaft 161. The external gear rings 17 can axially slide on the locking shaft 161. The external gear rings 17 are stepped rings, which can limit their own axial movement positions. When the large - diameter end of the external gear ring 17 abuts against the side surface of the hinge plate 131, the external gear ring 17 cannot move anymore.

[0040] The outer ring gear 17 is inserted between the hinge plate 131 and the extension plate 15. The outer ring gear 17, the hinge plate 131, and the extension plate 15 engage with each other, thereby restricting the extension plate 15 from rotating, preventing the telescopic rod 3 from pitching. In other words, to allow the locking shaft 161 to pass through, circular holes are formed in the hinge plate 131 and the extension plate 15. These holes are designed in the shape of inner ring gears, which match the outer ring gear 17, locking the hinge seat 13 and the extension plate 15 and preventing rotation.

[0041] The telescopic rod 3 is height-adjustable and consists of an inner rod 31 and an outer rod 32. Both rods are rectangular tubular. Extension plates 15 are located on either side of the lower end of the inner rod 31. The outer rod 32 is sleeved onto the inner rod 31 and can slide relative to it. A thumb screw 18 is located at the lower end of the outer rod 32. Multiple adjustment holes 19 are arranged in a straight line on the sidewall of the inner rod 31. Inserting a thumb screw 18 into any of the adjustment holes 19 locks the telescopic rod 3. A humanoid sensor 1 is located at the upper end of the outer rod 32.

[0042] The principle of this utility model is as follows: a mounting base 2 is mounted on a corresponding position of a transport vehicle via a flange 4 connection. The drive motor 22 within the mounting base 2 is powered by the vehicle's own power supply. Telescopic rods 3 with humanoid recognition sensors 1 are specifically mounted on the mounting base 2. The number, mounting position, angle, and height of the telescopic rods 3 can be selected based on the specific situation to accommodate different types of transport vehicles. The humanoid recognition sensors 1 are also powered by the vehicle's own power supply. The humanoid recognition sensors 1 monitor whether there are people in the transport vehicle's blind spot, preventing the vehicle from sensing and identifying people within the vehicle's blind spot when reversing.

[0043] During operation, the drive motor 22 reciprocates, driving the mounting shaft 23 and mounting plate 24. This causes the telescopic rod 3 to swing the human recognition sensor 1 back and forth, expanding its detection range. A controller and alarm are located near the driver's seat of the transport vehicle. The alarm, controller, and human recognition sensor 1 are electrically connected. When the sensor detects a person, it transmits a signal to the controller, which in turn triggers the alarm to sound an alarm, allowing the driver to brake the vehicle in time and ensure personal safety.

[0044] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
