Description
Technical Field
[0001] The utility model relates to the technical field of lifting robots, and particularly relates to a latent lifting robot. Background Art
[0002] Under the background of the rapid progress of contemporary technology, Automatic Guided Vehicles (AGVs) are increasingly widely used in the field of material handling, becoming an indispensable part of intelligent manufacturing systems, significantly enhancing the efficiency of production processes, and strongly promoting the informatization and intelligent transformation of industrial production. As a综合体 integrating multiple disciplines such as mechatronics, automation control, and information technology, the core position of the AGV control system is particularly prominent. Especially for the high reliability and accuracy requirements of the navigation system, it has become the key to ensuring the stable operation of AGVs.
[0003] However, in the existing AGV safety technologies, the commonly used rubber strip edge touch as an anti-collision measure has certain limitations. Although such anti-collision edges can relieve the collision impact to a certain extent, due to their installation position close to the vehicle body and the limited energy absorption capacity of the material, when the AGV comes into close contact with an obstacle and collides, they often cannot provide sufficient buffering effect to effectively resist deformation damage, which may affect the structural integrity and long-term operation stability of the AGV.
[0004] Therefore, exploring and developing more efficient and reliable AGV anti-collision mechanisms has become an important topic for improving the safety performance and operation flexibility of AGVs. Content of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a latent lifting robot to solve the technical problem of poor anti-collision effect of existing AGVs.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A latent lifting robot includes a vehicle body and an anti-collision structure. The anti-collision structure extends adaptively along the periphery of the vehicle body and includes a bottom plate and outer side plates and inner side plates integrally bent along the front and rear sides of the bottom plate. A buffer energy absorption area with a single-side opening in a "C" shape is enclosed among the bottom plate, the outer side plates, and the inner side plates. At least one energy absorption block densely paved between the outer side plates and the inner side plates is arranged in the buffer energy absorption area.
[0007] By adopting the above technical solution, through the integrally bent inner side plates, bottom plate, and outer side plates, a double-layer anti-collision energy absorption structure is formed. And with the energy absorption blocks arranged in the buffer energy absorption area, the collision energy can be further absorbed, providing sufficient buffering effect to effectively resist deformation damage.
[0008] The present utility model is further configured such that the energy absorption block is a flexible block, and a hard energy absorption core is coated on the inner side thereof.
[0009] By adopting the above technical solution, through the hard energy absorption core and the flexible block, progressive absorption and dispersion of external force impacts can be achieved. The flexible block first contacts and deforms to absorb the initial impact energy, and then the hard energy absorption core intervenes to further absorb the remaining impact force. This hierarchical energy absorption mechanism greatly improves the energy absorption efficiency, effectively protects the robot structure from severe impact damage, and also extends the service life of the anti-collision structure.
[0010] The present utility model is further configured such that the energy absorption block is a rubber block or a silicone block, and the energy absorption core is a cast aluminum block.
[0011] By adopting the above technical solution, using a rubber block or a silicone block as the outer energy absorption material can effectively absorb and disperse the energy at the initial stage of collision. The high elasticity of these two materials can reduce the impact force directly transmitted to the vehicle body. And the cast aluminum block used inside as the energy absorption core can continue to absorb the remaining high-intensity impact energy after the rubber or silicone reaches the limit deformation, and its rigid structure helps to prevent excessive deformation and maintain the stability of the overall structure.
[0012] The present utility model is further configured such that the anti-collision structure as a whole is in a "C" shape that wraps around the front side and both sides of the vehicle body, and transition edges are symmetrically formed on both sides thereof.
[0013] By adopting the above technical solution, the symmetric transition edges not only beautify the appearance, but more importantly, smooth the edge transition, reduce the stress concentration points during collision, make the force distribution more uniform, effectively avoid local damage, and enhance the overall protection performance of the robot.
[0014] The present utility model is further configured such that the transition edge is in a straight plate shape or an arc shape.
[0015] By adopting the above technical solution, the straight plate-shaped transition edge has a simple structure and low manufacturing cost, and is suitable for scenarios where a straight path needs to be quickly passed; while the arc-shaped transition edge can provide a smoother edge transition effect, reducing the risk of scratching caused by sharp edges, especially suitable for operating environments with limited space and frequent turning, enhancing the maneuverability of the robot and reducing the risk of collision damage.
[0016] The present utility model is further configured such that the ends on both sides of the anti-collision structure extend towards each other to form a reinforcing edge, and a reinforcing plate in a "C" shape and closely attached to its side is provided in the buffer energy absorption area opposite to the reinforcing edge.
[0017] By adopting the above technical solutions, the reinforcing edges designed at both ends of the anti-collision structure significantly enhance the structural strength of the "C"-shaped buffer energy absorption area. Especially when the robot is subjected to side impacts or squeezes, these reinforcing edges can provide additional support force to prevent irreversible deformation or damage of the energy absorption area due to excessive external forces. The reinforcing plate is installed closely against the side of the buffer energy absorption area, which not only strengthens the stability of this area but also optimizes the energy conduction path, making the energy absorption and distribution more uniform, and effectively improving the durability and reliability of the overall anti-collision system.
[0018] The present utility model is further configured such that on the side of the inner plate away from the bottom plate, a plurality of mounting edges perpendicular to its wall surface are integrally folded outward along its side edge, and mounting locking holes are provided on the mounting edges.
[0019] By adopting the above technical solutions, the mounting edges and the locking holes thereon greatly facilitate the assembly and fixation of the anti-collision structure. The mounting edges formed by the outward folding of the inner plate not only provide a stable foundation for installation but also ensure a tight fit with the vehicle body, improving the stability and sealing performance of the overall structure.
[0020] The present utility model is further configured such that a microswitch electrically connected to the control part of the vehicle body and used for stopping the vehicle body is provided on one of the mounting edges.
[0021] By adopting the above technical solutions, integrating the microswitch on the mounting edge and electrically connecting it to the vehicle body control part realizes the intelligent monitoring and emergency protection functions of the vehicle body state. When the robot encounters a strong collision and the anti-collision structure deforms to a certain extent, the microswitch will be triggered, immediately sending a signal to the control system to make the vehicle body perform an emergency stop operation, effectively preventing secondary injuries or equipment damage that may be caused by the collision.
[0022] The present utility model is further configured such that the microswitch has a trigger end, and a thin plate-shaped trigger plate is integrally extended from the trigger end, and the trigger plate extends along the buffer energy absorption area to a position close to the outer plate.
[0023] By adopting the above technical solutions, the trigger end of the microswitch is closely integrated with the buffer energy absorption area through the extended thin plate-shaped trigger plate. This layout makes the triggering mechanism more sensitive and accurate. The extended design of the trigger plate ensures that it can respond promptly even to slight collision deformations. Once the external force causes the energy absorption area to deform to a predetermined extent, the trigger plate will act immediately, activating the microswitch immediately, and thus quickly transmitting the stop instruction to the vehicle body control system. Thereby, the sensitivity and response speed of the safety protection mechanism can be fully optimized, ensuring that measures can be taken promptly at critical moments to prevent the expansion of damage, and further improving the safety performance and reliability of the robot.
[0024] The utility model is further configured such that the trigger plate extends obliquely and forms an angle less than 45° with the outer plate.
[0025] By adopting the above technical solution, an angle is formed between the trigger plate and the outer plate, which makes it easier for the trigger plate to induce induction at the trigger end in the event of collision deformation, thereby facilitating the triggering operation of the micro switch.
[0026] In summary, the utility model mainly has the following beneficial effects:
[0027] A double-layer anti-collision energy-absorbing structure is formed by the integrally bent inner plate, bottom plate and outer plate, and the energy-absorbing blocks arranged in the buffer energy-absorbing area can further absorb the collision energy, providing sufficient buffering effect to effectively resist deformation damage.
[0028] In summary, the latent lifting robot of the utility model not only improves the safety and efficiency of operations, but also takes into account the innovation and practicality of the structural design, providing a more advanced and reliable solution for material handling in intelligent manufacturing systems.

DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0035] The following describes an embodiment of the utility model based on its overall structure.
[0036] A lurking lifting robot, such as Figure 1-4 As shown, it includes a vehicle body 10 and a collision avoidance structure 20. The collision avoidance structure 20 extends adaptively along the peripheral side of the vehicle body 10 and includes a bottom plate 30, an outer side plate 40 and an inner side plate 50 which are integrally bent along the front and rear sides of the bottom plate 30. A buffer energy absorption area 21 with a single-sided opening in the shape of "匚" is formed by enclosing between the bottom plate 30, the outer side plate 40 and the inner side plate 50. At least one energy absorption block 70 densely paved between its outer side plate 40 and inner side plate 50 is provided in the buffer energy absorption area 21.
[0037] Preferably, the energy absorption block 70 is a flexible block, and a hard energy absorption core (not shown in the figure) is coated on its inner side. Through the hard energy absorption core and the flexible block, progressive absorption and dispersion of external force impacts can be achieved. The flexible block first contacts and deforms to absorb the initial impact energy, and then the hard energy absorption core intervenes to further absorb the remaining impact force. This hierarchical energy absorption mechanism greatly improves the energy absorption efficiency, effectively protects the robot structure from severe impact damage, and also extends the service life of the collision avoidance structure 20.
[0038] Preferably, the energy absorption block 70 is a rubber block or a silica gel block, and the energy absorption core is a cast aluminum block. Using a rubber block or a silica gel block as the outer energy absorption material can effectively absorb and disperse the energy in the initial stage of collision. The high elasticity of these two materials can reduce the impact force directly transmitted to the vehicle body 10. And the cast aluminum block used inside as the energy absorption core can continue to absorb the remaining high-intensity impact energy after the rubber or silica gel reaches the limit deformation. Its rigid structure helps to prevent excessive deformation and maintain the stability of the overall structure.
[0039] Preferably, the collision avoidance structure 20 is integrally in the shape of "匚" surrounding and covering the front side and both sides of the vehicle body 10, and transition edges 60 are symmetrically formed on both sides. The symmetrical transition edges 60 not only beautify the appearance, but more importantly, smooth the edge transition, reduce the stress concentration points during collision, make the force distribution more uniform, effectively avoid local damage, and enhance the overall protection performance of the robot.
[0040] Preferably, the transition edge 60 is in a straight plate shape or an arc shape (not shown in the figure). In this embodiment, it is in a straight plate shape. The straight plate-shaped transition edge 60 has a simple structure and low manufacturing cost, and is suitable for scenarios where a straight path needs to be quickly passed; while the arc-shaped transition edge 60 can provide a smoother edge transition effect, reducing the risk of scratching caused by sharp edges, especially suitable for operating environments with limited space and frequent turning, enhancing the maneuverability of the robot and reducing the risk of collision damage.
[0041] Preferably, the ends on both sides of the anti-collision structure 20 extend towards each other to form reinforcing edges 23. A reinforcing plate 24 in a "C" shape and closely attached to its side edges is arranged in the buffer energy absorption area 21 opposite to the reinforcing edges 23. The design of the reinforcing edges 23 at both ends of the anti-collision structure 20 significantly enhances the structural strength of the "C" - shaped buffer energy absorption area 21. Especially when the robot is subjected to side impacts or squeezes, these reinforcing edges 23 can provide additional support force to prevent irreversible deformation or damage of the energy absorption area due to excessive external force. The reinforcing plate 24 is installed closely attached to the side edges of the buffer energy absorption area 21, which not only strengthens the stability of this area but also optimizes the energy conduction path, making the energy absorption and distribution more uniform, and effectively improving the durability and reliability of the overall anti-collision system.
[0042] Preferably, on the side of the inner plate 50 away from the bottom plate 30, a plurality of mounting edges 22 perpendicular to its wall surface are integrally folded outwards along its side edges. Mounting locking holes (not shown in the figure) are provided on the mounting edges 22. The mounting edges 22 and the locking holes on them greatly facilitate the assembly and fixation of the anti-collision structure 20. The mounting edges 22 formed by folding the inner plate 50 outwards not only provide a stable foundation for installation but also ensure a tight fit with the vehicle body 10, improving the stability and sealing performance of the overall structure.
[0043] Preferably, a microswitch 80 electrically connected to the control part of the vehicle body 10 and used for stopping the vehicle body 10 is provided on one of the mounting edges 22. Integrating the microswitch 80 on the mounting edge 22 and electrically connecting it to the control part of the vehicle body 10 realizes the intelligent monitoring and emergency protection functions of the state of the vehicle body 10. When the robot encounters a strong collision and the anti-collision structure 20 is deformed to a certain extent, the microswitch 80 will be triggered, immediately sending a signal to the control system to make the vehicle body 10 perform an emergency stop operation, effectively preventing secondary injuries or equipment damage that may be caused by the collision.
[0044] Preferably, the microswitch 80 has a trigger end (not marked in the figure), and a thin -片状 trigger plate 81 extends integrally from the trigger end. The trigger plate 81 extends along the buffer energy absorption area 21 to a position close to the outer plate 40. The trigger end of the microswitch 80 is closely integrated with the buffer energy absorption area 21 through the extended thin -片状 trigger plate 81. This layout makes the trigger mechanism more sensitive and accurate. The extended design of the trigger plate 81 ensures that it can respond in a timely manner even to slight collision deformations. Once the external force causes the energy absorption area to deform to a predetermined extent, the trigger plate 81 will act immediately, activating the microswitch 80 immediately, and thus quickly transmitting the stop instruction to the control system of the vehicle body 10. Thereby, the sensitivity and response speed of the safety protection mechanism can be fully optimized, ensuring that measures can be taken quickly at critical moments to prevent the expansion of damage, and further improving the safety performance and reliability of the robot.
[0045] Preferably, the trigger plate 81 extends obliquely and forms an angle less than 45° with the outer plate 40. In addition, the trigger plate 81 is spaced 2-8 mm from the outer plate 40 so that an angle is formed between the trigger plate 81 and the outer plate 40 that makes it easier for the trigger plate 81 to induce trigger end induction in the event of collision deformation, thereby facilitating the triggering of the micro switch 80.
[0046] In particular, in this embodiment, the anti-collision structure 20 and the vehicle body 10 are installed in such a way that the anti-collision structure 20 is installed inverted, that is, the opening of its buffer energy absorption area 21 faces the ground, and the energy absorption block is installed inverted at the bottom of the buffer energy absorption area 21 by gluing or bolting.
[0047] In summary, the utility model mainly has the following beneficial effects:
[0048] A double-layer anti-collision energy absorption structure is formed by the integrally bent inner plate 50, bottom plate 30 and outer plate 40, and the energy absorption blocks 70 arranged in the buffer energy absorption area 21 can further absorb the collision energy and provide sufficient buffering effect to effectively resist deformation damage.
[0049] In summary, the latent lifting robot of the utility model not only improves the safety and efficiency of operations, but also takes into account the innovation and practicality of the structural design, providing a more advanced and reliable solution for material handling in intelligent manufacturing systems.
