Description
Technical Field
[0001] This utility model belongs to the field of chassis technology, and in particular relates to an intelligent robot chassis based on a four-laser sensor system. Background Technology
[0002] Intelligent robot chassis based on a four-laser sensor system is an important research area in current intelligent robot technology, especially in autonomous navigation, obstacle avoidance, localization, and environmental perception. The four-laser sensor system (usually referring to lidar or laser sensors) helps robots perform spatial localization and path planning by accurately measuring distance information of the surrounding environment, ensuring that they can move smoothly in complex environments.
[0003] According to a public disclosure of an intelligent robot chassis frame (publication number: CN212861684U), it includes a chassis body. The chassis body has a shock-absorbing groove inside. A matching limiting plate is fixedly connected to the inner side wall of the shock-absorbing groove. A shock-absorbing rod is movably sleeved inside the limiting plate. A positioning plate is fixedly sleeved on the outer side of the shock-absorbing rod. A shock-absorbing spring and a limiting sleeve are movably sleeved on the outer side of the shock-absorbing rod. The shock-absorbing spring and the limiting sleeve are both located inside the limiting plate and the positioning plate.
[0004] However, in the above design, when the intelligent robot is not running, there is no limiting device to limit its movement. When it is affected by external forces, it will be displaced and damaged, which needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent robot chassis based on a four-laser sensor system. Through the driving force of the casters, components such as the fixed plate, connecting rod, hollow block, sliding plate, spring, connecting plate, fixed rod, contact block, and through block cooperate with each other, enabling the casters set on the circumference of the connecting rod to run. After running for a period of time and then stopping, the operator presses down on the connecting plate fixed on the top of the sliding plate, thus solving the existing problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to an intelligent robot chassis based on a four-laser sensor system, comprising a chassis and a mounting base. The mounting base is fixedly connected to the top of the chassis. A moving mechanism is provided on the side of the chassis. The moving mechanism includes a fixed plate, which is fixedly connected to the side of the chassis. A connecting rod is fixedly connected to the bottom of the fixed plate. A caster wheel is provided on the circumferential surface of the connecting rod. A hollow block is fixedly connected to the top of the fixed plate. A sliding plate is slidably connected to the inner wall of the hollow block. A spring is fixedly connected to the bottom of the sliding plate, and the end of the spring away from the sliding plate is fixedly connected to the bottom of the inner wall of the hollow block. A connecting plate is fixedly connected to the top of the sliding plate. A fixed rod is fixedly connected to the bottom of the connecting plate. A contact block is fixedly connected to the circumferential surface of the fixed rod.
[0008] Furthermore, a through block is fixedly connected to the top of the connecting plate, a sliding groove is provided on the top of the chassis, a sliding block is slidably connected to the bottom of the inner wall of the sliding groove, and a limit plate is fixedly connected to the side of the sliding block. The above design facilitates operation by the staff.
[0009] Furthermore, the limiting plate is located inside the through block and contacts the top of the inner wall of the through block. The side cross-section of the contact block is set as trapezoidal. The above design is beneficial for limiting the contact block.
[0010] Furthermore, a clamping mechanism is provided on the top of the chassis. The clamping mechanism includes a rectangular plate, which is fixedly connected to the top of the chassis. A connecting shaft extends through the side of the rectangular plate. A threaded rod is fixedly connected to the circumferential surface of the connecting shaft. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A clamping plate is fixedly connected to the side of the threaded sleeve. The above design is beneficial for clamping the intelligent robot.
[0011] Furthermore, a limit block is fixedly connected to the bottom of the threaded sleeve, a hollow plate is fixedly connected to the top of the chassis, and a handle is fixedly connected to the circumferential surface of the connecting shaft. The above design facilitates the operation of the handle by the staff.
[0012] Furthermore, the limiting block is slidably connected to the inner wall of the hollow plate, and the side section of the threaded sleeve is set to a rectangle. The above design helps to enhance the stability of the threaded sleeve.
[0013] Furthermore, the moving mechanism is configured in two sets, and they are symmetrical to each other along the central axis at the bottom of the chassis. This design helps to enhance the operational stability of the chassis.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model utilizes the driving force of the universal wheels to drive the components such as the fixed plate, connecting rod, hollow block, sliding plate, spring, connecting plate, fixed rod, contact block, and through block to cooperate with each other, enabling the universal wheels set on the circumference of the connecting rod to run. After running for a period of time and then ceasing to run, the operator presses down on the connecting plate fixed to the top of the sliding plate, thereby driving the sliding plate sliding on the inner wall of the hollow block downwards. The downward movement of the sliding plate compresses the spring fixed at the bottom, keeping it in a taut state. When the intelligent robot stops moving, this prevents the chassis from shifting, thus preventing damage to the intelligent robot.
[0016] 2. This utility model utilizes the rotational force of the handle to drive the rectangular plate, connecting shaft, threaded rod, threaded sleeve, clamping plate, limiting block, hollow plate, and other components to work together. This allows the worker to rotate the handle fixed to the circumference of the connecting shaft after the intelligent robot is installed, thereby causing the connecting shaft to rotate. The rotation of the connecting shaft causes the threaded rod fixed to the circumference to rotate, and the rotation of the threaded rod causes the threaded sleeve threaded to the circumference to move. This enhances the stability of the intelligent robot after installation.
[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A spring 36 is fixedly connected to the bottom of the sliding plate 35, and the end of the spring 36 away from the sliding plate 35 is fixedly connected to the bottom of the inner wall of the hollow block 34. A connecting plate 37 is fixedly connected to the top of the sliding plate 35. A fixed rod 38 is fixedly connected to the bottom of the connecting plate 37. A contact block 39 is fixedly connected to the circumferential surface of the fixed rod 38.
[0028] A through block 310 is fixedly connected to the top of the connecting plate 37, and a sliding groove 311 is provided on the top of the chassis 1. A sliding block 312 is slidably connected to the bottom of the inner wall of the sliding groove 311, and a limit plate 313 is fixedly connected to the side of the sliding block 312. The above design is conducive to the operation of the staff.
[0029] The limiting plate 313 is located inside the through block 310 and contacts the top of the inner wall of the through block 310. The side section of the contact block 39 is set as trapezoidal. The above design is beneficial for limiting the contact block 39.
[0030] A clamping mechanism 4 is provided on the top of the chassis 1. The clamping mechanism 4 includes a rectangular plate 41, which is fixedly connected to the top of the chassis 1. A connecting shaft 42 passes through the side of the rectangular plate 41. A threaded rod 43 is fixedly connected to the circumference of the connecting shaft 42. A threaded sleeve 44 is threadedly connected to the circumference of the threaded rod 43. A clamping plate 45 is fixedly connected to the side of the threaded sleeve 44. The above design is beneficial for clamping the intelligent robot.
[0031] The bottom of the threaded sleeve 44 is fixedly connected to a limit block 46, the top of the chassis 1 is fixedly connected to a hollow plate 47, and the circumferential surface of the connecting shaft 42 is fixedly connected to a handle 48. The above design facilitates the operation of the staff by rotating the handle 48.
[0032] The limiting block 46 is slidably connected to the inner wall of the hollow plate 47, and the side section of the threaded sleeve 44 is set as rectangular. The above design helps to enhance the stability of the threaded sleeve 44.
[0033] The moving mechanism 3 is set in two groups and is symmetrical to each other along the central axis at the bottom of the chassis 1. This design helps to enhance the operational stability of the chassis 1.
[0034] A specific application of this embodiment is as follows: First, the worker places the robot inside the mounting base 2 for installation. After installation, the worker runs the caster 33 on the circumferential surface of the connecting rod 32. After running for a period of time and then stopping, the worker presses down on the connecting plate 37 fixed to the top of the sliding plate 35, thereby causing the sliding plate 35, which slides on the inner wall of the hollow block 34, to move downward. The downward movement of the sliding plate 35 compresses the spring 36 fixed at the bottom, putting it in a taut state. At the same time, the downward movement of the connecting plate 37 causes the fixed rod 38 fixed at the bottom to move downward. The downward movement of the fixed rod 38 causes the contact block 39 fixed on the circumferential surface to move downward. When the contact block 39 contacts the ground, the worker stops installing the connecting plate 37. At this time, the worker pushes the sliding block 312, which slides on the bottom of the inner wall of the slide groove 311, to slide, thereby causing the limiting plate 313 fixed on the side to move into the through block 3. The internal limit of block 310 is completed. When it is necessary to continue running, the staff pushes the sliding block 312 to slide, thereby causing the limit plate 313 fixed on the side to disengage from the inside of the through block 310. At this time, the spring 36 drives the sliding plate 35 to reset according to its own elasticity, so that the contact block 39 no longer contacts the ground. Finally, when the intelligent robot is installed, the staff rotates the handle 48 fixed on the circumferential surface of the connecting shaft 42, thereby driving the connecting shaft 42 to rotate. The rotation of the connecting shaft 42 drives the threaded rod 43 fixed on the circumferential surface to rotate. The rotation of the threaded rod 43 drives the threaded sleeve 44 threadedly connected to the circumferential surface to move. At the same time, the limit block 46 fixed at the bottom of the threaded sleeve 44 slides linearly on the inner side wall of the hollow plate 47. When the limit block 46 slides linearly, it drives the threaded sleeve 44 to move linearly, thereby driving the clamping plate 45 fixed on the side of the threaded sleeve 44 to move and contact the intelligent robot to clamp the intelligent robot.
