Description

Technical Field

[0001] This utility model relates to the field of automated logistics equipment technology, and in particular to an AGV transport robot. Background Technology

[0002] In automated logistics and industrial production, AGV (Automated Guided Vehicle) transport robots are key equipment connecting various processes and improving cargo transfer efficiency. However, existing AGV transport robots generally suffer from the following technical defects: Poor shock absorption makes goods easily damaged: Most equipment lacks professional shock absorption structure. When moving on uneven ground in the workshop or in the transition section of the connecting platform, the vibration is severe, which can easily cause precision parts and fragile items carried on the top to shift or be damaged. Insufficient stability: Some equipment has an unreasonable layout of drive wheels and casters, resulting in dispersed support force. When fully loaded with goods, it is prone to tilting, especially during turning, when the center of gravity is easily shifted. To address the shortcomings of existing technologies, there is an urgent need for an AGV (Automated Guided Vehicle) transport robot with dual shock absorption, omnidirectional obstacle avoidance, stable movement, and convenient maintenance. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an AGV transport robot. This robot aims to overcome the deficiencies of existing AGV transport robots, such as poor shock absorption, limited obstacle avoidance, inconvenient maintenance, and unstable movement. It provides a safe, stable, and easy-to-maintain AGV transport robot that achieves smooth cargo transport and efficient maintenance through dual precision shock absorption, lateral obstacle avoidance, and a convenient maintenance structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An AGV transport robot includes a base and a housing mounted thereon. An electronic control system and a power supply are respectively installed at the bottom of the base. A shock-absorbing mechanism 1 is installed at each of the four corners of the base. A caster wheel is installed at the bottom of the shock-absorbing mechanism 1. A shock-absorbing mechanism 2 is symmetrically arranged in the middle of the base. A drive mechanism is installed at the lower end of the shock-absorbing mechanism 2. A drive wheel is installed at the output end of the drive mechanism.

[0005] Preferably, the shock absorption mechanism includes a seat body 1 mounted on a base, a seat body 2 provided on the concave side of the seat body 1, and guide rods 1 and 2 respectively installed at the four corners and center of the seat body 2. The guide rods 1 and 2 are slidably connected to the seat body 1, and a nut 1 is threadedly connected to the end of the guide rod 2. An elastic element 1 is sleeved on the guide rod 2, and the elastic element 1 is located between the seat body 1 and the seat body 2. A caster wheel is installed at the bottom of the seat body 2.

[0006] Preferably, the second shock-absorbing mechanism includes a seat body three mounted on a base, a seat body four disposed on the concave side of the seat body three, a drive mechanism mounted on the seat body four, a drive wheel mounted on the output end of the drive mechanism, hinge seats hinged to both ends of the seat body four, a guide rod three connected to the top of the hinge seats, the guide rod three being slidably connected to the seat body three, a nut two being threaded to the upper end of the guide rod three, and an elastic element two being disposed on the section of the guide rod three located between the seat body three and the hinge seat.

[0007] Preferably, lateral proximity switches are provided at both the front and rear ends of the housing.

[0008] Preferably, the top of the housing is provided with an inspection port, and a cover plate is detachably connected to the inspection port, with a hidden handle provided on the cover plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are: Double shock absorption protects cargo: The four-corner shock absorption mechanism 1 works in conjunction with the central shock absorption mechanism 2. The elastic element buffers the vibration, and the guide rod ensures the accurate direction of shock absorption. This prevents vibration from being transmitted to the cargo when the robot moves on undulating ground, protecting precision parts and fragile items from shifting and damage, and improving the stability of transport.

[0010] Safer lateral obstacle avoidance: The lateral proximity switches at the front and rear ends of the housing can detect obstacles on the side and promptly link with the electronic control system to control deceleration or steering, filling the gap in lateral obstacle avoidance of traditional equipment and reducing the risk of collision when vehicles meet or people pass through narrow passages.

[0011] Flexible movement and stable support: Dual drive wheels combined with an electronic control system enable flexible steering, while omnidirectional wheels provide auxiliary support from the four corners. The overall layout is balanced, making it difficult to tilt even when fully loaded with goods, and it is suitable for complex workshop paths and narrow passages.

[0012] Convenient and time-saving maintenance: The top cover can be quickly removed with a hidden handle, and the access port can be opened without tools, which facilitates the maintenance of the internal electrical control system and power supply, shortens downtime for maintenance, and reduces operation and maintenance costs.

[0013] High structural adaptability: The preload of the elastic element in the shock-absorbing mechanism is adjustable, accommodating the transport needs of goods of varying weights; the concealed handle avoids snagging on goods, balancing functionality and practicality.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-6 An AGV transport robot includes a base 5 and a housing 1 mounted thereon. An electronic control system and a power supply 10 are respectively installed at the bottom of the base 5. A shock-absorbing mechanism 7 is installed at each of the four corners of the base 5. A caster wheel 6 is installed at the bottom of the shock-absorbing mechanism 7. A second shock-absorbing mechanism 9 is symmetrically arranged in the middle of the base 5. A drive mechanism 92 is installed at the lower end of the second shock-absorbing mechanism 9. A drive wheel 8 is installed at the output end of the drive mechanism 92.

[0019] In the shock absorption mechanism 7, seat 71 is fixed on base 5, and seat 72 is slidably connected to seat 71 via guide rod 73 and guide rod 74. Elastic element 76 is sleeved on guide rod 74. When the caster wheel 6 passes over uneven ground, seat 72 moves up and down along the guide rod, and elastic element 76 contracts or extends to buffer the vibration transmitted to base 5, preventing the goods on top of the shell 1 from shifting due to vibration. Nut 75 can adjust the preload of elastic element 76. When the goods are heavy, tighten elastic element 76 to enhance support, and loosen it when the goods are light to improve the shock absorption effect.

[0020] In the second shock-absorbing mechanism 9, the third seat 91 is fixed in the middle of the base 5, the fourth seat 93 is equipped with the drive mechanism 92 and the drive wheel 8, and the hinge seat 94 connects the fourth seat 93 and the guide rod 96. When the drive wheel 8 encounters bumps, the fourth seat 93 drives the hinge seat 94 to move up and down, the guide rod 96 ensures that the direction of movement is vertical, and the second elastic element 95 buffers the vibration. The hinge seat 94 can adjust its angle with the slight turning of the drive wheel 8 to avoid the shock-absorbing mechanism from jamming and improve the smoothness of movement. The second nut 97 can adjust the tightness of the second elastic element 95 to adapt to different road conditions.

[0021] The lateral proximity switches 4 at the front and rear ends of the housing 1 are linked with the electronic control system. When the robot moves, the lateral proximity switches 4 scan the environment in front and behind in real time. If an obstacle (such as a person or a shelf) is detected, the electronic control system immediately controls the drive mechanism 92 to decelerate or adjust the speed difference of the drive wheels 8 to achieve steering and avoid lateral collisions. The top cover 2 of the housing 1 can be quickly disassembled through the hidden handle 3. The inspection port can be opened without tools to inspect or replace the internal electronic control system and power supply 10, which greatly shortens the maintenance time.

[0022] During routine transport operations, power supply 10 supplies power to the equipment, and the electronic control system controls the drive mechanism 92 to drive the drive wheel 8 to rotate. The universal wheel 6 provides auxiliary support and steering, enabling the robot to move along a preset path. If the ground is uneven, the shock absorption mechanism 1 7 and the shock absorption mechanism 2 9 synchronously buffer the vibration to ensure the stability of the goods. When maintenance is required, the internal components can be operated by opening the cover plate 2 through the hidden handle 3.

[0023] The drive mechanism 92 provides power to the drive wheel 8, driving the entire vehicle body to move back and forth. Steering is achieved by the different rotation speeds of the two drive mechanisms 92. The casters 6 provide support to the base 5 from the four corners, ensuring the stability of the base 5. When passing over undulating road sections, guide rod 1 73, guide rod 2 74 and guide rod 3 96 provide guidance for the casters 6, the base 2 72 and the drive wheel 8. Elastic element 1 76 and elastic element 2 95 reduce the vibration of the base 5 and reduce the impact on the objects carried on the top of the shell 1.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
