Abstract
Description
Technical Field
[0001] The utility model relates to the field of warehouse logistics guidance, in particular to a guiding vehicle used for warehouse logistics. Background Art
[0002] In large logistics centers or warehouses, logistics guide vehicles are usually equipped with communication equipment that can contact the dispatch center. The guide vehicles mainly provide route guidance for other transport vehicles based on the system dispatch instructions, helping them reach their destination quickly and accurately, thereby improving transportation efficiency. In addition, the logistics guide vehicles can supervise operational safety and promptly identify and address safety hazards.
[0003] Since the guide vehicle needs to frequently travel in warehouses filled with goods, operators often encounter forklifts loading and unloading goods. However, when loading and unloading high-rise goods, the goods may fall due to external forces (such as vibration during forklift operation, or goods hitting other goods). If the guide vehicle happens to pass through this area, the fallen goods will fall onto the guide vehicle. However, the protective structure of the guide vehicle is usually only set on the outer edge, and there is no corresponding protective structure on its top, which makes the guide vehicle easily damaged by falling goods. Utility Model Content

DETAILED DESCRIPTION
[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figures 1 to 4The top of the buffer setting seat 6 is provided with a buffer top seat 7, and the top of the mounting seat 2 is provided with a buffer spring 3. The piston rod 5 is passed through the interior of the buffer spring 3, and one end of the buffer spring 3 is in contact with the mounting seat 2, and the other end of the buffer spring 3 is in contact with the buffer setting seat 6. The buffer spring 3 is located inside the buffer interval 23.
[0022] It can be understood that the two ends of the buffer spring 3 are respectively in contact with the mounting seat 2 and the buffer setting seat 6, forming a stable support and buffer structure, so that when the goods fall, the goods will first collide with the buffer top seat 7, and the impact force of the buffer top seat 7 will gradually be transmitted to the piston rod 5 and the buffer spring 3. The piston rod 5 is subjected to downward pressure, so that the movable end 24 slides downward along the movable cavity 25, and the buffer spring 3 cooperates to shrink, producing the effect of absorbing the impact force. Therefore, through the above-mentioned structural design, the top of the vehicle body 1 has an effective protection function, which can reduce the impact force caused by falling goods, significantly reduce the risk of damage to the vehicle body 1, and improve the safety and reliability of the overall operation; in addition, the design of the buffer spring 3 can absorb multiple impact forces while maintaining stable performance, thereby improving the service life of the system.
[0023] In this embodiment, the buffer spring 3 can be replaced with other elastic devices, such as gas springs or rubber buffers. The spring's stiffness parameters can also be adjusted to accommodate varying impact force requirements. The piston cylinder 4 can be made of other durable materials, such as aluminum alloy or stainless steel, to further enhance the strength and durability of the structure. The shape of the buffer seat 6 can be varied to achieve a wider range of adaptability.
[0024] A mounting groove 8 is provided at the bottom of the buffer top seat 7, and the mounting groove 8 matches the shape of the buffer setting seat 6. The mounting groove 8 is plugged into the buffer setting seat 6. First fixing holes 9 are provided on both sides of the buffer setting seat 6, and second fixing holes 10 are provided on both sides of the buffer top seat 7. The second fixing holes 10 are connected to the mounting groove 8. The second fixing holes 10 on both sides of the buffer top seat 7 correspond one-to-one to the first fixing holes 9 on both sides of the buffer setting seat 6. A fixing bolt 11 is passed through the second fixing hole 10, and the fixing bolt 11 is threadedly engaged with the adjacent first fixing hole 9.
[0025] It can be understood that when the buffer top seat 7 is damaged, the mounting groove 8 at its bottom is plugged into the buffer setting seat 6 to form a preliminary positioning structure. Through the one-to-one correspondence design of the first fixing hole 9 and the second fixing hole 10, the fixing bolt 11 is passed through to achieve reliable threaded fit, thereby ensuring the stable installation of the buffer top seat 7. This design allows the buffer top seat 7 to be quickly replaced by simply removing the fixing bolt 11 when it is damaged or worn, thereby shortening the downtime of the vehicle body 1 and improving the system operation efficiency.
[0026] In addition, the fixing method of the buffer top seat 7 can adopt other structures, such as realizing a detachable design through a snap-on method, thereby eliminating the bolt operation to further improve the replacement speed; the shape of the mounting groove 8 can also be designed to different geometric shapes (such as rectangle, circle, etc.) as needed to adapt to the structure of other types of buffer setting seats 6; in addition, the fixing bolt 11 can be replaced with a quick-release pin or knob locking device to further optimize the user maintenance experience.
[0027] Two guiding inclined surfaces 12 are provided on the top of the buffer top seat 7 , and the guiding inclined surfaces 12 are distributed in an eight-shaped pattern.
[0028] It can be understood that the two guide slopes 12 on the top of the buffer top seat 7 are arranged in an eight-shaped shape, so that the fallen cargo can slide to both sides when it contacts the buffer top seat 7, avoiding the cargo from accumulating on the top of the buffer top seat 7; this design effectively disperses the impact force of the cargo and further reduces the pressure on the buffer system by adjusting the force direction of the cargo; in addition, the eight-shaped slope design can help the cargo quickly detach from the surface of the buffer top seat 7, reducing the impact of repeated impacts on the vehicle body 1.
[0029] Furthermore, the surface material of the guide ramps 12 can be a low-friction material (such as a polytetrafluoroethylene coating) to further optimize the sliding effect of cargo. The angle of the ramps can be adjusted according to the specific usage scenario, for example, increasing the angle to increase the sliding speed, or decreasing the angle to slow the cargo's detachment. The number and distribution of the guide ramps 12 can also be adjusted as needed, for example, providing multiple sets of staggered ramps to accommodate the impact of cargo of different shapes.
[0030] A distance sensor 21 is provided on the top of the mounting top plate 22, and the identification end of the distance sensor 21 faces the buffer setting seat 6. A controller 20 is provided on one side of the vehicle body 1, and a buzzer 19 is provided on the other side of the vehicle body 1. The controller 20 is connected to the buzzer 19 and the distance sensor 21 signals through the wires inside the vehicle body 1.
[0031] It can be understood that by monitoring the real-time displacement of the buffer setting seat 6 through the distance sensor 21, the distance sensor 21 can send the displacement data to the controller 20 in real time. After receiving the data, the controller 20 can accurately judge the impact intensity of the top and promptly issue a warning to the operator through the buzzer 19. This design not only improves the safety protection capability of the vehicle body 1, but also can dynamically monitor the status of the buffer component, which is convenient for maintenance and management. Compared with the traditional non-monitoring design, this solution significantly enhances the safety and intelligence level.
[0032] Furthermore, the distance sensor 21 can utilize laser, infrared, or ultrasonic ranging technology, selecting the most appropriate detection method based on the application scenario. The controller 20 can integrate a fault logging function, storing detected displacement change data as a log for subsequent analysis and maintenance. Alarms can also be expanded to wireless signal transmission to a remote monitoring terminal, enabling centralized management.
[0033] A fixing groove 13 is formed on the top of the mounting top plate 22 , and a fixing column 14 is formed on the bottom of the mounting base 2 . The fixing column 14 is slightly larger than the fixing groove 13 , and the fixing column 14 is engaged with the fixing groove 13 .
[0034] It can be understood that when the buffer spring 3 or other internal components are damaged, the mounting base 2 can be separated from the fixing groove 13 by unlatching the fixing column 14, so that the entire buffer system can be quickly disassembled for replacement or maintenance. The fixing column 14 is designed to be slightly larger than the fixing groove 13, and a firm connection is achieved through interference fit when clamped, while ensuring the stability and vibration resistance of the structure.
[0035] The fixing post 14 can be designed with a tapered shape or a snap-fit mechanism to further simplify assembly and disassembly while enhancing positioning. A rubber gasket or elastic member can be added to the fixing slot 13 to improve the connection's cushioning performance and prevent wear from long-term use. If the use environment requires frequent replacement of the buffer assembly, the snap-fit mechanism can be replaced with a knob lock mechanism or quick-release plug to further improve replacement efficiency.
[0036] A first mounting groove 15 is provided at the top of the mounting seat 2, one end of the buffer spring 3 is plugged into the first mounting groove 15, and the piston cylinder 4 is installed inside the first mounting groove 15. A second mounting groove 17 is provided at the bottom of the buffer setting seat 6, the other end of the buffer spring 3 is plugged into the second mounting groove 17, and the other end of the piston rod 5 is installed inside the second mounting groove 17.
[0037] It can be understood that the first mounting groove 15 and the second mounting groove 17 are respectively located at the two ends of the mounting seat 2 and the buffer setting seat 6, and are used to position the buffer spring 3 to ensure that the buffer spring 3 does not undergo lateral displacement or fall off when it is deformed.
[0038] The depth and shape of mounting groove 8 can be adjusted based on spring specifications to accommodate buffer springs 3 of varying diameters or lengths. If higher positioning accuracy is required, a guide structure or elastic gasket can be added to mounting groove 8 to enhance the securing effect. Furthermore, the buffer spring 3 positioning method can be replaced with a snap-fit mechanism or threaded fit, with the optimal solution selected based on actual usage requirements.
[0039] First latching protrusions 16 are provided on both sides of the first mounting groove 15, and one end of the buffer spring 3 is engaged with the first latching protrusions 16 on both sides of the first mounting groove 15. Second latching protrusions 18 are provided on both sides of the second mounting groove 17, and the other end of the buffer spring 3 is engaged with the second latching protrusions 18 on both sides of the second mounting groove 17.
[0040] It can be understood that the double fixation of the buffer spring 3 by the first latch 16 and the second latch 18 solves the problem of spring displacement or falling off due to strong impact or long-term use, which significantly improves the safety and durability of the buffer system. In addition, the latch design is simple, easy to produce and install, while maintaining the compactness of the structure.
[0041] Furthermore, the first and second latching protrusions 16 and 18 can be designed with rounded bumps, trapezoidal projections, or tooth-shaped structures to meet different strength requirements and usage scenarios. For even higher retention performance, a non-slip coating or additional elastic pressure plates can be added to the latching surfaces. Furthermore, the latching protrusions can be replaced with a latching mechanism or threaded locking device to further enhance the spring's positioning.
[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
