Description

Technical Field

[0001] This utility model relates to the field of forklift anti-collision alarm technology, specifically to an anti-collision device for electric forklifts used in material delivery. Background Technology

[0002] In modern logistics warehousing and industrial production, electric forklifts are increasingly widely used as efficient material handling equipment. However, due to their structural design, electric forklift operators are generally seated at a high height during actual operation, creating blind spots in critical operations such as turning and inserting goods. These blind spots not only obstruct the operator's observation of the surrounding environment but also make it difficult to accurately judge the movement of people and the placement of goods, greatly increasing the risk of collisions between the forklift and personnel or goods. Such accidents can cause injuries or fatalities, damage to goods, and disruption of work processes, resulting in significant economic losses for businesses. They also seriously threaten the overall safety and order of the work site, posing a significant safety hazard.

[0003] The patent with publication number CN118373356A discloses a work monitoring device for forklift forks. It uses a first monitoring probe fixed to the tip of the fork arm, along with a second monitoring probe that can be adjusted in both vertical height and horizontal position to assist in detecting the area around the forklift. The device can adjust the forklift in a timely manner based on the monitoring situation to avoid collisions or even damage to goods due to the driver's limited field of vision.

[0004] However, the second monitoring probe in the aforementioned forklift fork work monitoring device is installed at the top of the fork carriage behind the fork arm. In order to achieve stable installation of the second monitoring probe and adjust its vertical height and horizontal position, additional fixed and horizontal parts are set up, which increases the structural complexity of the top of the fork carriage and also significantly increases the overall volume of the forks, affecting the forklift's flexibility and making it more difficult for the forklift to turn, avoid obstacles, and insert goods. Utility Model Content

[0005] To address the technical problem that existing forklift fork monitoring devices are bulky, affecting forklift maneuverability and making it more difficult for forklifts to turn, avoid obstacles, and insert goods, this utility model provides an anti-collision device for electric forklifts used in material delivery.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A collision avoidance device for an electric forklift used for material delivery includes L-shaped forks. Each fork includes a vertically mounted frame and a horizontally mounted shovel. The right side of the frame is connected to the shovel, and the length of the shovel is arranged laterally. A groove is provided on the right side of the frame, and a fixing mechanism is installed in the groove. The fixing mechanism includes a mounting plate, on which a rotating shaft is rotatably connected. The axis of the rotating shaft is arranged longitudinally, and a monitoring probe is connected to the outside of the rotating shaft. One end of the rotating shaft is coaxially fixedly connected to a gear. Gear 1 meshes with gear 2, and gear 2 is coaxially fixedly connected to the output shaft of a servo motor. The servo motor is fixedly mounted on the mounting component, which is fixedly mounted in the groove.

[0007] The above structural design achieves several advantages. First, the monitoring probe is mounted in a recess on the right side of the upright via a fixing mechanism, eliminating the need for a complex structure on the top of the fork carriage. This allows for monitoring of the environment around the pallet while avoiding an increase in the overall size of the forks, ensuring the forklift's flexibility when turning, avoiding obstacles, and inserting goods. This effectively solves the problem of reduced forklift flexibility caused by monitoring devices in existing technologies. Second, when the servo motor is working, its output shaft drives gear two to rotate. Gear two meshes with gear one, which in turn drives the rotating shaft to rotate. The rotating shaft drives the externally connected monitoring probe to rotate, allowing for flexible adjustment of the monitoring angle according to operational needs, expanding the monitoring coverage, and providing a more comprehensive view of personnel movement and goods placement around the pallet, reducing the risk of collisions. Third, the mounting plate, rotating shaft, gear one, gear two, servo motor, and mounting components of the fixing mechanism are all integrated into the recess of the upright. This compact structure does not occupy extra space outside the forks and does not interfere with the original operating functions of the forklift, ensuring normal material handling operations.

[0008] As a preferred implementation of an anti-collision device for electric forklifts used for material delivery, there are two mounting plates, with the surfaces of the two mounting plates facing each other and arranged in parallel. The two mounting plates are arranged in the longitudinal direction, and the monitoring probe is located between the two mounting plates.

[0009] With the above structural design, the two mounting plates are arranged in parallel and longitudinal direction with their surfaces facing each other. The monitoring probe is located between the two mounting plates. The two mounting plates can support the rotating shaft from both sides of the monitoring probe, preventing the rotating shaft from shaking or shifting during the rotation of the monitoring probe. This ensures the stability of the monitoring probe during operation, ensures clear and accurate monitoring images, and avoids safety hazards caused by monitoring failure due to unstable installation.

[0010] As a preferred implementation of an anti-collision device for an electric forklift used for material delivery, both gear one and gear two are bevel gears, and the output shaft of the servo motor is vertically arranged.

[0011] Using the above structural design, both gear one and gear two are bevel gears. Bevel gears have the characteristic of changing the direction of power transmission. Combined with the vertical mounting method of the servo motor output shaft, the vertical output power of the servo motor can be converted into the longitudinal rotational power of the shaft, saving space. In addition, when the bevel gears mesh, the transmission ratio is accurate and the transmission efficiency is high, which can ensure that the power of the servo motor is stably and efficiently transmitted to the shaft. This makes the rotation adjustment response of the monitoring probe rapid and the angle control precise, avoiding the problems of untimely and inaccurate monitoring caused by transmission lag or angle deviation.

[0012] As a preferred implementation of an anti-collision device for an electric forklift used for material delivery, transverse grooves are opened on both the front and rear sides of the shovel plate. The length of the transverse grooves is set in the transverse direction. A servo push rod is fixedly connected in the transverse groove. A moving block is fixedly connected to the output end of the servo push rod. A radar unit is connected to the side of the moving block facing the opening of the transverse groove.

[0013] The above structural design incorporates radar units on both the front and rear sides of the shovel. These radar units can detect obstacles and personnel in the front and rear directions of the shovel, complementing the monitoring probes to provide comprehensive collision warnings around the shovel. This further reduces blind spots, improves operational safety, and prevents accidents caused by omissions in single monitoring methods. When the servo push rod is in operation, its output can drive a moving block to move along the transverse groove, thereby moving the radar units laterally. This allows for flexible adjustment of the radar units' transverse detection position based on the size and placement of materials on the shovel, as well as changes in the operational environment. This expands or focuses the detection range, ensuring effective detection of critical areas and improving warning accuracy.

[0014] As a preferred implementation of an anti-collision device for electric forklifts used for material delivery, the moving block is a rectangular block structure with slide rails on both the upper and lower sides. The slide rails extend laterally and are slidably connected to the upper and lower sides of the transverse groove.

[0015] With the above structural design, the slide rails on the upper and lower sides of the moving block extend laterally and slide connected to the upper and lower sides of the transverse groove. These slide rails guide the movement of the moving block, preventing it from shifting, jamming, or wobbling as it moves along the transverse groove under the drive of the servo push rod. This ensures the moving block can smoothly and steadily move the radar unit, guaranteeing the accuracy of the radar unit's detection position adjustment. Furthermore, the sliding connection method makes the fit between the moving block and the transverse groove tighter, reducing displacement of the moving block in non-moving directions and preventing loosening of the moving block due to forklift vibration during operation. This, in turn, ensures the stability of the radar unit during detection, guaranteeing accurate and reliable detection data.

[0016] As a preferred implementation of an anti-collision device for electric forklifts used for material delivery, the slide is a raised strip, and the upper and lower sides of the transverse groove are provided with strip-shaped grooves that are adapted to the slide.

[0017] The above structural design features a raised rib on the slide rail, with matching strip-shaped grooves on both the upper and lower sides of the transverse groove. The rib and the strip-shaped grooves engage in an embedded sliding mechanism. Compared to ordinary sliding connections, this more precisely restricts the movement direction of the moving block, further preventing deviation during movement and providing superior guidance. This ensures the radar unit can accurately move to the target detection position. Furthermore, the embedded engagement of the raised rib and the strip-shaped groove increases the contact area between the moving block and the transverse groove, resulting in more even force distribution when the moving block bears the weight of the radar unit and operational vibrations. This reduces localized wear, improves the overall structural load-bearing capacity and service life, and lowers the risk of failure due to structural wear.

[0018] As a preferred implementation of an anti-collision device for electric forklifts used for material delivery, the moving block has a mounting slot on the side facing the transverse slot opening, and the radar unit is installed in the mounting slot.

[0019] The above structural design includes a mounting slot on the side of the moving block facing the transverse slot opening. The radar unit is installed in the mounting slot, which positions and secures the radar unit, preventing it from detaching or shifting from the moving block due to vibration or collision during operation. This ensures the installation stability of the radar unit and guarantees its normal detection function. Furthermore, the mounting slot provides protective enclosure for the sides and bottom of the radar unit, reducing the entry of external dust and debris. It also minimizes direct collision damage from goods and obstacles during operation, extending the radar unit's lifespan and reducing maintenance frequency and costs.

[0020] As a preferred implementation of an anti-collision device for electric forklifts used in material delivery, the mounting slot is horn-shaped.

[0021] The above-described structural design features a funnel-shaped mounting slot with its opening facing outwards from the transverse slot and gradually widening. This reduces the obstruction of the radar unit's detection signal, allowing the radar unit's signal to cover a wider area around the shovel plate. It also more effectively receives reflected signals, improving the radar unit's detection range and sensitivity, and avoiding blind spots caused by the mounting slot's obstruction. Furthermore, the funnel-shaped structure guides and converges the radar signal, reducing signal dispersion and ensuring the signal is more concentratedly transmitted to the target area. It also enhances the reception strength of reflected signals, improving the radar unit's ability to detect distant or small obstacles, and increasing the timeliness and accuracy of collision warnings.

[0022] As a preferred implementation of an anti-collision device for electric forklifts used for material delivery, a mounting bracket is fixedly provided on the left side of the upright. The front and rear edges of the mounting bracket extend beyond the front and rear edges of the upright. The mounting bracket has horizontal mounting openings on both the front and rear sides. The mounting bracket is connected to the forklift by bolts passing through the mounting openings.

[0023] With the above structural design, the front and rear edges of the mounting bracket on the left side of the upright extend beyond the front and rear edges of the upright, and both sides have transverse through-hole mounting openings. Bolts passing through these mounting openings allow for a stable connection between the mounting bracket and the forklift, thus enabling the assembly of the entire anti-collision device with the forklift. The larger mounting bracket coverage and the dual mounting opening design distribute the connection points more evenly, preventing excessive stress on a single point that could lead to loosening and ensuring the stability of the device during forklift operation.

[0024] As a preferred implementation of an anti-collision device for electric forklifts used for material delivery, a buzzer and a warning light are provided on the top of the stand, and both the buzzer and the warning light are remotely connected to the radar unit.

[0025] With the above structural design, when the radar unit detects personnel, obstacles, or other potential collision risks around the forklift, it immediately transmits signals to the buzzer and warning light. The buzzer emits a high-decibel sound signal, and the warning light emits a high-frequency flashing light signal, instantly alerting the forklift operator and surrounding personnel to the collision risk. Compared to a single monitoring screen alert, this warning is more direct and conspicuous, effectively shortening reaction time and reducing the probability of accidents. Furthermore, forklift operation sites may experience noise interference or distracted personnel. Relying solely on the operator's observation of the monitoring screen or radar detection data can easily lead to missed risk warnings due to limited perspective and lack of concentration. The buzzer's sound signal can cover a certain range of the work area, allowing surrounding personnel to perceive risks through sound even if they are not directly looking at the forklift or monitoring equipment. The warning light's light signal has stronger visual penetration in dimly lit warehouse environments or complex work scenarios, allowing personnel at a distance to quickly detect dangerous conditions around the forklift, further expanding the warning coverage and reducing blind spots.

[0026] The beneficial effects of this utility model include: 1. The monitoring probe is installed in the groove on the right side of the upright frame through a fixing mechanism, eliminating the need for an additional complex structure on the top of the fork carriage. While achieving monitoring of the environment around the fork plate, it avoids increasing the overall size of the forks, ensuring the flexibility of the forklift when turning, avoiding obstacles, and inserting goods, and effectively solving the problem of reduced forklift flexibility caused by monitoring devices in existing technologies.

[0027] 2. When the servo motor is working, its output shaft drives gear two to rotate. Gear two meshes with gear one, which in turn drives the rotating shaft to rotate. The rotating shaft drives the externally connected monitoring probe to rotate. The monitoring angle of the monitoring probe can be flexibly adjusted according to the operation requirements, expanding the monitoring coverage area and allowing for a more comprehensive observation of the movement trajectory of personnel and the placement of goods around the shovel, thus reducing the risk of collision accidents.

[0028] 3. The mounting plate, shaft, gear one, gear two, servo motor and mounting parts of the fixed mechanism are all integrated into the groove of the upright, which is compact and does not occupy extra space outside the forks, nor will it interfere with the original operation function of the forklift, ensuring normal material handling operation of the forks.

[0032] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Reference Figure 1 and Figure 2 A collision avoidance device for an electric forklift used for material delivery includes L-shaped forks 1. The forks 1 include a vertically arranged support frame 104 and a horizontally arranged shovel plate 101. The right side of the support frame 104 is connected to the shovel plate 101. The length direction of the shovel plate 101 is transverse, and the upper surface of the right side of the shovel plate 101 slopes downwards to the right. In this embodiment, the transverse direction is the forklift's travel direction. A groove is provided on the right side of the support frame 104, and a fixing mechanism 3 is installed in the groove. The fixing mechanism 3 includes two mounting plates 303, whose surfaces are opposite and parallel, arranged longitudinally. A rotating shaft 301 is rotatably connected between the two mounting plates 303. The axis of the rotating shaft 301 is longitudinally arranged, and a monitoring probe 3011 is connected to the outer circumferential surface of the rotating shaft 301. The monitoring probe 3011 is located between the two mounting plates 303. Figure 6 One end of the rotating shaft 301 extends through the mounting plate 303 and is coaxially and fixedly connected to gear one 3012. Gear one 3012 meshes with gear two 3022, and gear two 3022 is coaxially and fixedly connected to the output shaft of servo motor 3021. Both gear one 3012 and gear two 3022 are bevel gears. The output shaft of servo motor 3021 is vertically arranged, and servo motor 3021 is fixedly mounted on mounting piece 302. Mounting piece 302 is fixedly mounted in a groove, and mounting piece 302 serves to fix servo motor 3021. The battery of servo motor 3021 can also be installed in the groove; the battery is a rechargeable battery.

[0034] Reference Figure 1 and Figure 3 The shovel plate 101 has transverse grooves 105 on both its front and rear sides. The length of the transverse grooves 105 is transversely oriented. A servo push rod 2 is fixedly connected within each transverse groove 105. A moving block 201 is fixedly connected to the output end of the servo push rod 2. The moving block 201 is a rectangular block structure. Slides 2011 are provided on both the upper and lower sides of the moving block 201. The slides 2011 are raised strips extending transversely. Strip-shaped grooves matching the slides 2011 are provided on the upper and lower sides of the transverse grooves 105, allowing the moving block 201 to slide smoothly into the transverse grooves 105. (Refer to...) Figure 5The movable block 201 has a horn-shaped mounting slot 2013 on the side facing the opening of the transverse slot 105, and the radar unit 2012 is installed in the mounting slot 2013. The battery of the servo push rod 2 can be installed in the transverse slot 105. The top of the stand 104 is equipped with a buzzer 103 and a warning light 1031. Both the buzzer 103 and the warning light 1031 are remotely connected to the radar unit 2012. A controller (not shown in the figure) can be connected between the radar unit 2012, the buzzer 103, and the warning light 1031. The controller can process the electrical signals of the radar unit 2012.

[0035] To simplify wiring, the controller in this embodiment can be a microcontroller with Wi-Fi capability (such as an ESP32) connected to the radar unit 2012. When the radar detects an object, it sends a message (e.g., via MQTT protocol or HTTP request) to a server or directly to the alarm device via the Wi-Fi network. Another microcontroller with Wi-Fi capability (or the same one) is connected to the buzzer 103 and the warning light 1031. It constantly listens for messages on the network and immediately triggers the buzzer 103 and the warning light 1031 upon receiving an alarm command. Alternatively, the controller in this embodiment can be a Bluetooth controller. A microcontroller with Bluetooth capability (such as an ESP32 or Arduino Nano 33 BLE) is connected to the radar unit 2012. When an object is detected, it broadcasts a signal or sends data to the paired alarm device via Bluetooth. Another microcontroller with Bluetooth capability is connected to the buzzer 103 and the warning light 1031. It continuously scans for or waits for Bluetooth signals from the radar and triggers the alarm upon receiving one.

[0036] Reference Figure 1 , Figure 2 and Figure 4 A mounting bracket 102 is fixedly provided on the left side of the upright frame 104. The front and rear edges of the mounting bracket 102 extend beyond the front and rear edges of the upright frame 104. The front and rear sides of the mounting bracket 102 are provided with mounting openings 1021 that extend horizontally through the mounting bracket 102. The mounting bracket 102 is connected to the forklift by bolts passing through the mounting openings 1021.

[0037] The upper surface of the right side of the forklift 101 slopes downwards to the right, forming an inclined guide surface. When the forklift inserts into the bottom of the goods, the inclined surface guides the forklift, reducing frictional resistance between the forklift 101 and the bottom of the goods. This allows the forklift 101 to be inserted more easily and smoothly, reducing the difficulty of picking up goods and improving operational efficiency. Furthermore, the inclined upper surface prevents the right edge of the forklift 101 from scraping against the bottom of the goods. This is especially beneficial for goods with fragile packaging or easily damaged surfaces, effectively reducing damage during picking, minimizing economic losses due to damage, and ensuring the quality of material delivery.

[0038] When handling small-sized and low-height goods, the monitoring probe 3011 will not be obstructed. Operators can rely on the images transmitted by the monitoring probe 3011 to observe surrounding obstacles and personnel, and at the same time rely on the radar unit 2012 to detect surrounding obstacles and personnel, which greatly improves operational safety.

[0039] This embodiment is not only suitable for handling small, low-height goods, but also for handling large, high-height goods. Although the goods may obstruct the monitoring probe 3011, preventing it from functioning properly for visual observation, operators can still rely on the radar unit 2012 to effectively detect surrounding obstacles and personnel, avoiding safety hazards caused by blind spots. Furthermore, to enhance the detection coverage, a notch can be provided at the right end of the shovel plate 101, and another radar unit can be installed in the notch to specifically detect obstacles and personnel in the area in front. This effectively compensates for the blind spots of the monitoring probe 3011, ensuring that even when the view is obstructed by goods, a comprehensive and blind-spot-free perception of the surrounding environment can be achieved, providing continuous and stable safety assurance for goods handling operations.

[0040] Working principle: The entire fork 1 is connected and fixed to the forklift using bolts through the mounting port 1021 of the mounting bracket 102 on the left side of the upright 104. The front and rear edges of the mounting bracket 102 extend beyond the upright 104, and the double mounting port 1021 design ensures a stable connection between the fork 1 and the forklift, preventing loosening due to vibration during operation.

[0041] After power is applied, the servo motor 3021 drives the gear 3022 to rotate. The gear 3022 meshes with the gear 3012 to drive the rotating shaft 301, adjusting the monitoring probe 3011 to the initial monitoring angle.

[0042] After the monitoring probe 3011 is activated, it continuously collects image information around the forklift 101 and transmits the image to the display terminal in the forklift cab, allowing the operator to observe the distribution of personnel, goods, and obstacles near the forklift 101 in real time. When the forklift turns, inserts goods, or moves materials of different heights, the operator can remotely control the rotation angle of the output shaft of the servo motor 3021 via buttons, joysticks, or a touch screen to adjust the rotation angle of the monitoring probe 3011, thereby flexibly monitoring the angle, eliminating blind spots, and ensuring that the monitoring coverage matches the work scenario. The transmission path of the control signal of the servo motor 3021 can be the forklift's own circuit system or an independent control system. The servo motor 3021 can achieve precise positioning through an encoder.

[0043] After the radar units 2012 on the front and rear sides of the shovel plate 101 are activated, they transmit detection signals in the front and rear directions of the shovel plate 101 to monitor the distance and movement trajectory of obstacles and personnel in that direction in real time. If the distance is detected to be too close, the buzzer 103 and the warning light 1031 will sound an alarm.

[0044] Depending on the size, placement, or changes in the work environment of the material on the shovel plate 101, the operator can remotely control the servo push rod 2 to extend or retract from the cab, thereby moving the moving block 201 along the transverse groove 105 to adjust the detection position and improve detection accuracy.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
