Description

Technical Field

[0001] This utility model relates to the field of devices, and in particular to an obstacle warning camera for intelligent forklift control. Background Technology

[0002] The obstacle warning camera for smart forklifts is a camera device specifically designed for smart forklift systems. It aims to identify obstacles in the forklift's path in advance and issue warnings by capturing and analyzing images of the surrounding environment, thereby ensuring safe forklift operation and effectively preventing collision risks.

[0003] During the lifting or lowering of goods, the limited operating space and the varying positions and shapes of the goods pose a risk of collisions with the camera. For example, when loading and unloading irregularly shaped or large metal products, even slight movement during hoisting can cause the goods to directly impact the camera located on top of the forklift. A collision can damage the camera's casing or lens, rendering it unable to detect obstacles. Consequently, the forklift will be unable to rely on the camera to detect surrounding obstacles during subsequent movement, greatly increasing the risk of accidents such as collisions with shelves or other equipment. Therefore, this paper proposes a smart forklift obstacle warning camera to address these issues. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 4This utility model provides an embodiment of an obstacle warning camera for intelligent forklift control, comprising a forklift 1, which serves as the main support for the entire device, providing the mounting base and mobile platform for components such as the camera 5 and the alarm 3. This allows the entire obstacle warning system to move flexibly with the forklift 1 within the work area, enabling obstacle monitoring at different locations. Three protective shells 2 are fixedly connected to the top of the forklift 1, serving as crucial protective carriers for internal components such as the camera 5. These shells effectively block external dust, debris, and collisions from damaging internal components such as the camera 5 and the lighting 7, creating a relatively safe and stable working environment and extending the service life of the components. An alarm 3 is fixedly connected to the top of the forklift 1, providing an early warning function. When the camera 5 detects an impending collision with an obstacle, it promptly issues an alarm signal to alert the forklift driver, allowing for swift action to prevent collisions and ensure the safe operation of the forklift 1. Each of the four protective housings 2 has a protective glass 4 fixedly connected inside. Installed inside the housing 2, this not only does not obstruct the normal shooting field of the camera 5 but also provides physical protection, preventing dust and moisture from directly adhering to the camera lens and ensuring the clarity of the captured image. Each of the three protective housings 2 also has a fixedly connected camera 5, the core image acquisition component responsible for capturing real-time image information of the forklift 1's surrounding environment. This provides visual data support for obstacle detection and is the basic sensing element for obstacle warning. A mounting plate 6 is fixedly connected to the side of the protective glass 4 closest to the camera 5, used to fix a lighting lamp 7, providing a stable mounting position for the lamp and ensuring that the lamp 7 can provide supplemental lighting to the camera 5 at the appropriate angle and position. Four lighting lamps 7 are fixedly connected inside the mounting plate 6, providing illumination to the camera 5 in low-light operating environments, enhancing ambient brightness, and enabling the camera 5 to clearly capture surrounding objects. Each of the three protective shells 2 has a sliding plate 8 inside, which cooperates with the protective shell 2 to form a protective mechanism, protecting internal components such as the camera 5. Furthermore, when the camera 5 needs to be disassembled, the sliding plate 8 can be slid to facilitate the removal and maintenance of the camera 5, improving the maintainability of the device. A limiting block 11 is rotatably connected inside the sliding plate 8 to support the handle 9, allowing the handle 9 to rotate inside the sliding plate 8. The handle 9 is fixedly connected inside the limiting block 11, facilitating the installation and removal of the camera 5 and improving the ease of installation and removal. A threaded rod 12 is fixedly connected to the bottom of the handle 9. Through threaded engagement with a threaded sleeve 13, the rotational motion of the handle 9 is converted into the linear motion of the threaded sleeve 13, providing power transmission for the subsequent movement of the fixed rod 16. This is a key transmission component for enabling the fixed rod 16 to engage or disengage from the fixing hole of the protective shell 2.The threaded rod 12 has a threaded sleeve 13 on its external thread. Driven by the threaded rod 12, it moves linearly, which in turn pushes the connecting block 15 and the fixed rod 16 to move via the connecting rod 14. It is the intermediate component connecting the rotation of the handle 9 and the linear movement of the fixed rod 16, realizing the conversion and transmission of motion. Connecting rods 14 are rotatably connected to both sides of the threaded sleeve 13, connecting the threaded sleeve 13 and the connecting block 15. The linear movement of the threaded sleeve 13 is transmitted to the connecting block 15, enabling the connecting block 15 to drive the fixed rod 16 to move, thus transmitting force. The connecting block 15 is fixedly connected to the side of the connecting rod 14 away from the threaded rod 12, connecting the connecting rod 14 and the fixed rod 16. The force transmitted from the connecting rod 14 is transmitted to the fixed rod 16, pushing the fixed rod 16 to move. The fixed rod 16 is fixedly connected to the side of the connecting block 15 away from the threaded rod 12. Under the push of the relevant components, it can engage with the fixing hole of the protective shell 2, thus fixing the camera 5 inside the protective shell 2. The top of the forklift 1 is equipped with a fixing structure, which is used to fix the protective shell 2.

[0019] Reference Figure 1 , Figure 4 The fixing mechanism includes two fixing brackets 17, which are fixed to the top of the forklift 1 by screws 18. These brackets provide the mounting base for components such as locking plate 1 20 and locking plate 21, and are crucial support components for fixing the protective shell 2 to the top of the forklift 1, ensuring the stability of the protective shell 2 installation. The bottoms of both fixing brackets 17 are fixedly connected to the top of the forklift 1 by screws 18. The screws 18, through threaded connection, provide a reliable and strong fastening force between the fixing brackets 17 and the top of the forklift 1, firmly fixing the fixing brackets 17 to the forklift 1. The tops of the two fixing brackets 17 are fixedly connected to rotating columns 19, providing rotational support for locking plate 1 20 and locking plate 21, allowing them to rotate around the columns to achieve clamping, fixing, or releasing operations on the protective shell 2. Two mounting brackets 17 are rotatably connected to a locking plate 20 on the top of one of the brackets closest to the slide plate 8, and a locking plate 21 is rotatably connected to the top of the brackets 17 furthest from the slide plate 8. Locking plate 20 and locking plate 21 cooperate, and with the support of the rotating column 19, can clamp and fix the protective shell 2. With the cooperation of the pin 10, the protective shell 2 can be securely fixed to the top of the forklift 1, preventing it from loosening. The locking plate 21 has a sliding pin 10 inside, used to lock the relative positions of locking plate 20 and locking plate 21, ensuring the fixing effect of the mounting brackets 17 on the protective shell 2 and preventing the protective shell 2 from loosening or shifting due to vibration or other factors during forklift 1 operation.

[0020] Reference Figure 2 , Figure 3The mounting plate 6 is externally fixed to the inside of the protective shell 2, forming a stable integral structure between the mounting plate 6 and the protective shell 2. This prevents the mounting plate 6 from shifting or shaking due to vibration, collision, or other factors during forklift operation. The handle 9 is externally rotatably connected to the inside of the slide plate 8, facilitating the engagement or disengagement of the fixing rod 16 with the fixing holes of the protective shell 2, thus improving the convenience of installing and removing the camera 5 and other related operations.

[0021] Reference Figure 3 The threaded sleeve 13 is externally slidably connected to the inside of the slide plate 8, and the connecting block 15 is externally slidably connected to the inside of the slide plate 8. The slide plate 8 provides precise guidance for the movement of the threaded sleeve 13 and the connecting block 15. When the threaded sleeve 13 moves linearly due to the rotation of the threaded rod 12, and when the connecting block 15 moves under the push of the connecting rod 14, the sliding connection structure of the slide plate 8 ensures that they move smoothly along a specific trajectory, avoiding deviation, wobbling, etc., and ensuring the accuracy and stability of the movement.

[0022] Reference Figure 3 The external sliding connection of the fixing rod 16 is inside the slide plate 8, which provides precise guidance for the fixing rod 16, ensuring that the fixing rod 16 moves along a specific trajectory during movement, and can accurately and smoothly engage or disengage with the fixing hole of the protective shell 2.

[0023] Reference Figure 3 The protective shell 2 has fixing holes inside, and the fixing rod 16 passes through the sliding plate 8 and engages with the fixing holes of the protective shell 2 to prevent the camera 5 from shifting due to vibration or bumps of the forklift 1 during operation. This ensures that the camera 5 is always in a suitable shooting position, guaranteeing that it can continuously and accurately collect image information of the environment around the forklift 1, providing a stable visual data source for obstacle detection.

[0024] Reference Figure 4 Locking plate 20 is rotatably connected to the outside of rotating column 19 on the side near the fixing frame 17, and locking plate 21 is rotatably connected to the outside of rotating column 19 on the side near the fixing frame 17. This allows locking plate 20 and locking plate 21 to rotate flexibly around rotating column 19. When fixing or disassembling the protective shell 2, locking plate 20 and locking plate 21 can be easily rotated to a suitable position, which is convenient for operators to install or disassemble and improves the ease of operation.

[0025] Reference Figure 4The opposite side of locking plate 20 contacts the opposite side of locking plate 21. When fixing the protective shell 2, locking plates 20 and 21 ensure that they clamp the protective shell 2 in a suitable and stable posture, preventing the protective shell 2 from shifting position due to vibration, bumps, or other factors during forklift operation. The bottom of pin 10 is slidably connected to the inside of locking plate 20, making it easier to lock or unlock locking plates 20 and 21. Simply sliding pin 10 can lock or unlock both, facilitating the installation, disassembly, and maintenance of the protective shell 2, and improving the operability and maintenance efficiency of the device.

[0026] Working principle: Rotating the handle 9 drives the threaded rod 12 to rotate, causing the threaded sleeve 13 to move. This, in turn, pushes the fixing rod 16 through the connecting rod 14 and connecting block 15, engaging the fixing rod 16 with the fixing hole of the protective shell 2. The camera 5 is then installed inside the protective shell 2. To remove the camera 5, the operation is reversed; the sliding plate 8 can then be slid upwards to remove the camera 5. The protective shell 2, together with the sliding plate 8 and protective glass 4, forms a protective mechanism to protect the camera 5. The camera 5 inside the protective shell 2 is used to capture images of the forklift 1's surrounding environment. The four lights 7 on the mounting plate 6 provide illumination in low-light conditions, ensuring the camera 5 can clearly capture images. When the camera 5 detects that the forklift 1 is about to collide with a wall, object, or other obstacle, it transmits a signal to the alarm 3, which then sounds an alarm to alert the driver and prevent a collision.

[0027] The protective shell 2 is fixed by a fixing mechanism. The bottom of the two fixing brackets 17 in the fixing structure is fixed to the top of the forklift 1 with screws 18. The rotating column 19 at the top of the fixing bracket 17 is used to connect the locking plate 1 20 and the locking plate 21. The locking plate 1 20 and the locking plate 21 cooperate, and the protective shell 2 can be firmly fixed to the forklift 1 by the pin 10.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
