Description

Technical Field

[0001] This utility model relates to the field of stacking unmanned forklift technology, specifically to a multi-angle adjustable mounting component for obstacle avoidance radar of a stacking unmanned forklift. Background Technology

[0002] In the field of industrial warehousing and logistics transportation, stacker-type unmanned forklifts have become core equipment for realizing intelligent handling and storage of goods due to their automated and highly efficient operation advantages. Among them, obstacle avoidance radar, as a key sensing component for the safe operation of stacker-type unmanned forklifts, undertakes the important function of real-time detection of obstacles in the surrounding environment and avoiding collision risks. Its detection performance directly determines the safety and reliability of forklift operation.

[0003] Currently, the obstacle avoidance radar mounting components used on the bottom of stacker-type unmanned forklifts are relatively simple, generally achieving fixed installation only through a combination of radar mounting brackets and fixed brackets. These components can only achieve angle adjustment in a single direction (left / right or pitch), severely lacking in adjustment flexibility. Since the effective obstacle avoidance range of obstacle avoidance radar typically needs to cover an area of ​​5 to 6 meters, extremely high requirements are placed on the flatness of its installation. Even if the overall installation angle deviation of the obstacle avoidance radar is as low as 1° to 2°, it is still very easy for the radar scanning area to cover the ground, thereby triggering false obstacle avoidance signals, interfering with the normal operation of the forklift, and even causing equipment shutdown, affecting warehouse operation efficiency.

[0004] Meanwhile, these traditional mounting components are highly dependent on the flatness of the reserved mounting position on the stacking unmanned forklift body. However, the stacking unmanned forklift itself is a complex device assembled from multiple modules. In the production, processing and assembly of components such as the frame, chassis, and functional modules, dimensional errors and assembly deviations are inevitable. After the accumulation of various errors, it is very easy to cause unevenness on the radar mounting reference surface (such as the mounting area at the bottom of the forklift), further aggravating the problem of installation angle deviation of the obstacle avoidance radar, making it difficult to meet the high precision requirements of the radar scanning surface. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-angle adjustable installation component for obstacle avoidance radar on stacking unmanned forklifts. The aim is to solve the problems of existing obstacle avoidance radar installations on stacking unmanned forklifts, such as limited angle adjustment direction, difficulty in adapting to harsh working conditions, and susceptibility to cumulative errors leading to false obstacle avoidance.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a multi-angle adjustable mounting assembly for an obstacle avoidance radar on a stacking unmanned forklift, including a stacking forklift, an obstacle avoidance radar, a collision avoidance edge frame, a fixed bracket, an adjustable bracket, a radar mounting bracket, a first bolt, and a second bolt. The collision avoidance edge frame is connected and fixed to the stacking forklift by bolts, and the obstacle avoidance radar is installed inside the collision avoidance edge frame. The fixed bracket is fixed inside the collision avoidance edge frame by bolts. The adjustable bracket is fixed to the fixed bracket by the first bolt, and one side of the adjustable bracket has an arc-shaped groove for adjusting the left and right angles of the adjustable bracket relative to the fixed bracket. The radar mounting bracket is fixed to the adjustable bracket by the second bolt, and the radar mounting bracket has a pair of arc-shaped grooves for adjusting the pitch angle of the radar mounting bracket relative to the adjustable bracket. The obstacle avoidance radar is fixed to the radar mounting bracket.

[0008] Furthermore, the arc-shaped slot on the adjusting bracket extends horizontally, and the first bolt passes through the arc-shaped slot to connect the adjusting bracket to the fixed bracket.

[0009] Furthermore, a pair of arc-shaped slots on the radar mounting bracket are symmetrically distributed along the vertical direction, and a second bolt passes through the pair of arc-shaped slots to connect the radar mounting bracket to the adjustment bracket.

[0010] Furthermore, the anti-collision edge frame is a frame structure, with an internal installation space for accommodating the fixed bracket, the adjustable bracket, the radar mounting bracket, and the obstacle avoidance radar.

[0011] Furthermore, the fixed bracket is a plate-shaped structure with bolt connection holes at both ends that are adapted to the anti-collision contact frame and the adjustment bracket, and the bolt connection holes adapted to the adjustment bracket are used to mate with the first bolt for installation.

[0012] Furthermore, the adjusting bracket has a bent structure, with one end connected to the fixed bracket by a first bolt and the other end connected to the radar mounting bracket by a second bolt.

[0013] Furthermore, the radar mounting bracket includes a support plate and connecting ears. The support plate is used to fix the obstacle avoidance radar, and the connecting ears are symmetrically arranged on both sides of the support plate. The pair of arc-shaped slots are respectively opened on the two connecting ears, and the arc-shaped slots are used to cooperate with the second bolt for installation.

[0014] Furthermore, the anti-collision contact frame is provided with multiple bolt mounting holes, the number of which is the same as the number of bolt connection holes on the fixed bracket.

[0015] Furthermore, the curvature of the arc-shaped slot on the adjustment bracket is adapted to the adjustment range of the obstacle avoidance radar in the left and right directions, and the diameter of the arc-shaped slot is adapted to the outer diameter of the first bolt.

[0016] Furthermore, the curvature of each arc-shaped slot on the radar mounting bracket is adapted to the adjustment range of the obstacle avoidance radar's pitch direction, and the aperture of each arc-shaped slot is adapted to the outer diameter of the second bolt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Achieves flexible bidirectional adjustment to adapt to diverse working conditions. Compared to the limitations of traditional mounting components that can only achieve single-direction (left / right or pitch) angle adjustment, this component, through the combination of "adjustment bracket + first bolt + horizontal arc-shaped slot", can precisely achieve left / right angle adjustment of the obstacle avoidance radar. Through the combination of "radar mounting bracket + second bolt + vertical symmetrical arc-shaped slot", it can stably complete pitch angle adjustment. The bidirectional adjustment function can flexibly adapt to various extreme working conditions such as long-distance pitch angle obstacle avoidance and near-end low-height pitch angle obstacle avoidance, breaking the working condition adaptation limitations of traditional components and improving the operational adaptability of unmanned forklifts in complex warehouse environments.

[0019] 2. Counteracting cumulative errors and reducing the risk of accidental obstacle avoidance. Addressing the issue of uneven radar mounting surfaces caused by cumulative errors in the multi-module assembly (frame, chassis, functional modules, etc.) of stacking automated forklifts, this component's bidirectional angle adjustment capability actively corrects these errors. Even if the anti-collision edge frame experiences angular deviation due to cumulative errors, adjusting the left and right angles of the adjustment brackets and the pitch angle of the radar mounting brackets can calibrate the radar's scanning surface to the target area. This prevents the radar from scanning the ground due to a 1°-2° angular deviation, thereby reducing the triggering of accidental obstacle avoidance signals, ensuring continuous automated forklift operations, and improving warehouse operation efficiency.

[0020] 3. Ensures installation accuracy and meets radar scanning requirements. Traditional mounting components lack sufficient adjustment capabilities, making it difficult to meet the high precision requirements of obstacle avoidance radar for the scanning surface. In this component, the arc-shaped groove of the adjustment bracket adapts to left and right adjustment needs, and the arc-shaped groove of the radar mounting bracket adapts to pitch adjustment needs. Furthermore, the groove diameters precisely match the outer diameters of the first and second bolts, enabling fine-tuning of the angle. This ensures the angular accuracy of the obstacle avoidance radar scanning surface, fully leveraging its 5-6 meter effective obstacle avoidance range and improving the safety and reliability of unmanned forklift operations.

[0021] 4. High structural adaptability, convenient and efficient installation. The structural design and connection relationship of each component in the assembly are highly compatible. The frame structure of the anti-collision contact edge bracket provides stable housing space for internal components. The plate structure of the fixed bracket can be adapted to the connection of both the anti-collision contact edge bracket and the adjustment bracket. The bending structure of the adjustment bracket facilitates the connection of bidirectional components. The "bearing plate + symmetrical connecting ears" design of the radar mounting bracket not only facilitates the fixing of the radar, but also ensures the stability of the pitch adjustment. Moreover, all connections are achieved by bolts. The installation process does not require complicated tools and can be completed with simple assembly. Compared with traditional components, it does not significantly increase the installation cost and time, and takes into account both practicality and economy.

[0022] 5. High versatility and ease of standardized application. The structural design of this component is not tied to a specific model of stacker forklift or obstacle avoidance radar. The anti-collision contact frame can be adapted to the mounting interfaces of different forklifts via bolts. The connection holes and bolt specifications of the fixed bracket, adjusting bracket, and radar mounting bracket can be flexibly adjusted according to actual needs. Furthermore, the bidirectional adjustment function is compatible with obstacle avoidance radars with different detection parameters, making it universally applicable to various forklift models from different manufacturers. This reduces the difficulty of equipment maintenance and replacement, facilitates standardized production and mass application, and supports the large-scale deployment of unmanned forklift obstacle avoidance systems.

[0027] Before introducing the embodiments of this utility model, the core components and related relationships involved in this utility model will be introduced first.

[0028] Stacking forklift 1: As the base for component installation, its bottom has a pre-set anti-collision contact frame installation area. This area needs to be cleaned to ensure that the installation surface is free of oil and impurities, so as to provide a stable installation benchmark for the anti-collision contact frame 3.

[0029] Anti-collision edge bracket 3: Made of metal frame structure, the internal space size is adapted to the overall volume of fixed bracket 5, adjusting bracket 4, radar mounting bracket 7 and obstacle avoidance radar 6. The surface has 4 bolt mounting holes for connection with fixed bracket 5. The number of bolt mounting holes is the same as the number of bolt connection holes at the corresponding end of fixed bracket 5.

[0030] Adjustment bracket 4: Made of bent metal sheet with a bending angle of 90°, one side has an arc-shaped slot extending horizontally, the arc of which is adapted to the left and right adjustment requirements of obstacle avoidance radar 6, and the gap between the slot hole diameter and the outer diameter of the first bolt 8 is ≤0.5mm; one end of adjustment bracket 4 is connected to fixed bracket 5 through the first bolt 8, and the other end has a bolt hole adapted to radar mounting bracket 7, which is connected through the second bolt 9.

[0031] Fixed bracket 5: Made of cold-rolled steel plate, the thickness is adapted to the load-bearing requirements. One end has 4 connection holes that are adapted to the bolt mounting holes of the anti-collision contact frame 3, and the other end has 1 bolt connection hole that is adapted to the adjusting bracket 4, for installation with the first bolt 8.

[0032] Obstacle avoidance radar 6: An industrial-grade obstacle avoidance radar with a conventional detection range is selected. The bottom is provided with mounting holes that are compatible with the support plate of the radar mounting bracket 7. It is fixed to the support plate with bolts and is housed inside the anti-collision contact frame 3.

[0033] Radar mounting bracket 7: includes an integrally formed metal support plate and two symmetrical connecting ears. The surface of the support plate has fixing holes adapted to the obstacle avoidance radar 6. The two connecting ears are respectively set on both sides of the support plate. Each connecting ear has an arc-shaped slot distributed in the vertical direction. The arc of the slot is adapted to the pitch adjustment requirements of the obstacle avoidance radar 6. The gap between the slot diameter and the outer diameter of the second bolt 9 is ≤0.5mm.

[0034] The first bolt 8 and the second bolt 9 are both high-strength internal hex bolts. The outer diameter of the first bolt is compatible with the arc-shaped slot diameter of the adjusting bracket 4, and the outer diameter of the second bolt is compatible with the arc-shaped slot diameter of the radar mounting bracket 7. The tightening torque is ≥15N・m to ensure that the components are firmly connected after adjustment.

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0036] refer to Figure 1-5 The component installation process of this utility model embodiment is as follows:

[0037] Clean the pre-installed anti-collision guard plate mounting area on the bottom of the stacker forklift 1, removing surface oil, dust, and impurities to ensure a flat mounting surface. Attach the anti-collision guard plate 3 to the mounting area, aligning the bolt holes on the anti-collision guard plate 3 with the connection holes on the forklift body. Use appropriate bolts to pass through the aligned holes and tighten each bolt individually with a wrench to ensure the anti-collision guard plate 3 is securely fixed to the stacker forklift 1 without any loosening or misalignment.

[0038] Remove the fixing bracket 5 and place it inside the anti-collision edge bracket 3, ensuring that the end of the fixing bracket 5 with four connection holes faces the bolt mounting holes of the anti-collision edge bracket 3. Align the bolt connection holes of the fixing bracket 5 with the bolt mounting holes of the anti-collision edge bracket 3; pass bolts through the aligned holes and tighten them to securely connect the fixing bracket 5 and the anti-collision edge bracket 3, ensuring that the fixing bracket 5 remains horizontal and without tilting.

[0039] Orient the bent end of the adjusting bracket 4 toward the radar installation direction, so that the side with the arc-shaped groove fits against the free end of the fixed bracket 5; align the arc-shaped groove of the adjusting bracket 4 with the matching bolt connection hole of the fixed bracket 5, and pass the first bolt 8 through the arc-shaped groove and the bolt connection hole. Do not tighten the first bolt 8 at this time, so as to leave room for the adjusting bracket 4 to move along the groove.

[0040] With the support plate of the radar mounting bracket 7 facing upwards, attach the connecting ears on both sides to the free end of the adjusting bracket 4; align the arc-shaped groove on the connecting ear with the corresponding mounting hole of the adjusting bracket 4, pass the second bolt 9 through the groove and the mounting hole, and do not tighten the second bolt 9 yet, leaving space for the radar mounting bracket 7 to rotate along the groove.

[0041] Place the obstacle avoidance radar 6 on the support plate of the radar mounting bracket 7, aligning the mounting holes on the bottom of the radar with the fixing holes on the support plate; use the adapter bolts to pass through the aligned holes and tighten them to fix the obstacle avoidance radar 6 to the support plate, ensuring that the radar does not shake and that the detection direction is consistent with the preset obstacle avoidance direction. At this time, the obstacle avoidance radar 6 is completely contained inside the anti-collision contact frame 3.

[0042] refer to Figure 1-5 The multi-angle adjustment operation of this utility model embodiment is as follows: (a) Adjustment of the left and right angles based on the adjustment bracket 4

[0043] The obstacle avoidance system of the stacking unmanned forklift 1 is activated. The scanning area feedback of the obstacle avoidance radar 6 is observed in real time through the display interface of the forklift control system to determine whether there is a left or right deviation of the scanning surface (such as deviating to the left or right, and not covering the target obstacle avoidance area).

[0044] If adjustment is required, loosen the first bolt 8 with an Allen wrench (no need to completely disassemble, leave a slight connection to prevent parts from falling off).

[0045] Push the adjustment bracket 4 to move left and right along its horizontally extending arc-shaped slot: when the scanning surface is biased to the left, push the adjustment bracket 4 to the right; when the scanning surface is biased to the right, push the adjustment bracket 4 to the left, while observing the scanning feedback in real time, until the scanning surface covers the left and right range of the target.

[0046] After confirming that the adjustment is in place, tighten the first bolt 8 to securely connect the adjusting bracket 4 and the fixed bracket 5, preventing displacement during subsequent operations. (ii) Pitch angle adjustment based on radar mounting bracket 7

[0047] Continue to observe the scanning surface of obstacle avoidance radar 6 through the display interface of the unmanned forklift control system to determine whether there is any pitch deviation (such as the scanning surface being too high, causing near-end missed scans, or too low, touching the ground, causing false triggering).

[0048] If adjustment is required, loosen the second bolt 9 with an Allen wrench (no need to completely disassemble).

[0049] The radar mounting bracket 7 rotates up and down along its vertically symmetrically distributed arc-shaped slots: when the scanning surface is too high, the radar mounting bracket 7 rotates downward; when the scanning surface is too low, the radar mounting bracket 7 rotates upward, while monitoring the scanning feedback, until the scanning surface accurately covers the target's elevation range.

[0050] After confirming that the adjustment is in place, tighten the second bolt 9 to fix the radar mounting bracket 7 and the adjustment bracket 4, thus completing the overall angle calibration.

[0051] Compared with the prior art, the multi-angle adjustable installation component for the stacking unmanned forklift obstacle avoidance radar of this utility model, combined with the component design, installation operation and adjustment logic in the specific implementation process, has the following significant beneficial effects.

[0052] 1. Precise and controllable bidirectional adjustment, adaptable to diverse and complex working conditions. In specific implementation, the adjustment bracket 4 adopts a bent structure, with a horizontally extending arc-shaped slot on one side that precisely matches the first bolt 8 (the gap between the slot diameter and the bolt outer diameter is ≤0.5mm). During installation, simply loosening the first bolt 8 allows the adjustment bracket 4 to move left and right along the slot, achieving left and right angle adjustment of the obstacle avoidance radar 6. Meanwhile, the radar mounting bracket 7 has symmetrically arranged vertical arc-shaped slots on its two connecting ears, used in conjunction with the second bolt 9. Loosening the bolt and rotating the radar mounting bracket 7 allows for stable adjustment of the pitch angle of the obstacle avoidance radar 6. This dual-adjustment structure of "horizontal slot + vertical slot" breaks the limitations of traditional components' single-directional adjustment, flexibly adapting to diverse needs in warehousing scenarios. For example, when facing distant shelves, the elevation angle of the obstacle avoidance radar 6 can be raised by adjusting the radar mounting bracket 7 to ensure long-distance detection coverage; for low obstacles at close range, the radar mounting bracket 7 can be adjusted downward to achieve low-height detection, effectively improving the operational adaptability of the stacking unmanned forklift 1 in complex warehousing environments.

[0053] 2. Actively offsetting accumulated errors significantly reduces the risk of accidental obstacle avoidance. The stacking unmanned forklift 1 is assembled from multiple components such as the frame, chassis, and functional modules. Accumulated errors are easily generated during production and assembly, resulting in uneven mounting reference surfaces for the anti-collision contact frame 3. In practice, even if the anti-collision contact frame 3 deviates at an angle due to errors, it can be actively corrected through two steps: first, loosen the first bolt 8 and push the adjusting bracket 4 along the horizontal slot to calibrate the left and right angles of the obstacle avoidance radar 6; then, loosen the second bolt 9 and rotate the radar mounting bracket 7 along the vertical slot to adjust the pitch angle. Through this bidirectional adjustment, the scanning surface of the obstacle avoidance radar 6 can be accurately calibrated to the target area, avoiding radar scanning covering the ground due to a small angular deviation of 1°-2°, thereby reducing the triggering of accidental obstacle avoidance signals, ensuring the continuity of the stacking unmanned forklift 1's operation process, and significantly improving warehouse operation efficiency.

[0054] 3. Refined Adjustment Ensures Precision and Fully Utilizes Radar Performance. Traditional mounting components, due to their simple adjustment structure, struggle to meet the high precision requirements of obstacle avoidance radar for its scanning surface. This component employs multiple safeguards for adjustment precision in its design and implementation: the curvature of the horizontal arc-shaped slot on the adjustment bracket 4 is customized to the actual left-right adjustment needs of the obstacle avoidance radar 6, ensuring the adjustment range matches the radar's detection requirements; the curvature of the vertical arc-shaped slot on the radar mounting bracket 7 also adapts to the pitch adjustment needs of the obstacle avoidance radar 6, preventing over- or under-adjustment; simultaneously, the slot diameter precisely matches the outer diameter of the corresponding bolts (first bolt 8, second bolt 9), with a gap ≤0.5mm, ensuring smooth adjustment and preventing component wobbling after adjustment. This refined design and implementation enables precise control of the obstacle avoidance radar 6's angle, ensuring its scanning surface stably covers an effective obstacle avoidance range of 5-6 meters, fully utilizing the radar's detection performance, and significantly improving the safety and reliability of the stacking unmanned forklift 1 operation.

[0055] 4. Strong structural adaptability, convenient installation, and high economy. From the perspective of component structure and installation process in specific implementation, the adaptability of each component in this assembly is extremely high: the anti-collision contact frame 3 adopts a frame structure, with internal space precisely accommodating the fixed bracket 5, adjusting bracket 4, radar mounting bracket 7, and obstacle avoidance radar 6, protecting internal components while ensuring compact installation; the fixed bracket 5 is a plate-like structure with bolt holes at both ends adapted to the anti-collision contact frame 3 and adjusting bracket 4, achieving efficient connection; the bending structure of the adjusting bracket 4 (such as a 90° bend) can be flexibly adapted to the installation space of the stacking unmanned forklift 1, facilitating bidirectional component connection; the "bearing plate + symmetrical connecting ears" design of the radar mounting bracket 7 facilitates stable fixing of the obstacle avoidance radar 6 and ensures force balance during pitch adjustment. In addition, all components are connected by bolts, and the installation process only requires conventional tools such as wrenches. No complicated equipment is needed. The process can be completed by following the steps of "installing the anti-collision contact frame 3 → fixing the bracket 5 → connecting the adjustment bracket 4 and the radar mounting bracket 7 → fixing the obstacle avoidance radar 6". Compared with traditional components, it does not significantly increase the installation cost and time, and takes into account both practicality and economy.

[0056] 5. High versatility and wide compatibility, facilitating standardization and large-scale application. In practical implementation, this component is not tied to a specific model of stacker forklift or obstacle avoidance radar, exhibiting high versatility: multiple bolt mounting holes are provided on the anti-collision contact frame 3, allowing for adaptation to the mounting interfaces of different stacker forklifts 1 by changing the bolt positions; the bolt connection hole specifications of the fixed bracket 5, adjusting bracket 4, and radar mounting bracket 7 can be flexibly adjusted according to actual needs to adapt to obstacle avoidance radars 6 of different sizes; simultaneously, the bidirectional adjustment function is not limited by radar detection parameters and is compatible with various types of industrial-grade obstacle avoidance radars. This versatility design allows this component to adapt to various stacker forklift models from different manufacturers, reducing the difficulty of adaptation during equipment maintenance and replacement. In actual production and application, mass production can be carried out based on a unified structural standard, reducing customization costs, facilitating standardized application, and providing strong support for the large-scale deployment of stacker unmanned forklift obstacle avoidance systems.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various improvements and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
