[0002] The robot mobile base is the placement support device of the robot. It can support and fix the robot, and at the same time facilitate the movement and transportation of the robot and the use of the robot.
[0003] After searching, a Chinese patent discloses a mobile base for a robot (publication number CN212795019U). This patented technology adjusts the distance between the two mounting seats and uses the telescopic effect of the spring to reduce the distance between the mounting seats, which is convenient for clamping and fixing the robot, and is protected by a protective pad to prevent clamping damage. The mounting rod and the movable wheel are pushed out of the column groove by the squeezing effect of the push rod and the pulley, which is convenient for moving the robot. However, in the technical solution of the above patent document, the robot is simply pulled and fitted by a spring, and the placement is unstable. When the elastic force is pulled, the arc shape at the bottom and the spring pull make the robot unstable when pressed down, and it is easy to shake.
[0004] Therefore, a mobile base for a robot is proposed to solve the above problems. Utility Model Content

The driving direction can be changed through the worm and the worm wheel, and the rotation adjustment is made more stable.
[0009] Preferably, two groups of the stabilizing components are provided, and each group of the stabilizing components includes a stabilizing groove opened on one side of the side push frame. The side end of the base frame is fixedly connected to a stabilizing rod, and the stabilizing rod slides with the inner wall of the stabilizing groove.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.
[0023] When implementing: Figure 1-4As shown, a mobile base for a robot comprises: a base frame 1, side push frames 2 are arranged on both sides of the base frame 1, and retractable moving mechanisms 3 are installed on the inner walls of the two side push frames 2; a pushing mechanism 4 is used to adjust the distance between the two side push frames 2 and the base frame 1, and the pushing mechanism 4 for controlling the fitting effect is arranged on one side of the base frame 1; an elastic fitting component 5 is used to elastically fit the side push frames 2 and the robot to prevent excessive extrusion; wherein, the pushing mechanism 4 comprises a synchronous approaching component 401 arranged on one side of the base frame 1, and a stabilizing component 402 is arranged on one side of the synchronous approaching component 401. When the robot is placed and moved conveniently by using this device, the robot is placed on the upper side of the base frame 1. , and then the two side push frames 2 are fitted to the robot through the synchronous approach component 401, and the two ends of the machine are fixed when it is placed. At the same time, the elastic fitting component 5 makes the pushing mechanism 4 push and fit the robot, so that the robot will not be over-extruded when it is fixed to prevent damage. At this time, the robot is stably placed on the upper side of the base frame 1, and can be conveniently placed and transported by extending and retracting the retractable moving mechanism 3. The retractable moving mechanism 3 includes a buckle extending part and a pushing wheel part, which can be fixed after the moving wheel is extended, which is convenient for transportation or the side push frame 2 is stably placed when the moving wheel is retracted. Since the retractable moving mechanism 3 has the same structure as the extending and moving parts in the comparative document, it will not be described in detail here.
[0024] like Figure 3 and Figure 4As shown, a worm wheel 4014 is fixedly connected to the circumferential surface of the bidirectional lead screw 4011, a rotating frame 4016 is fixedly connected to the lower end of the base frame 1, and a worm 4015 is rotatably connected to the inner wall of the rotating frame 4016. The worm 4015 is meshed with the worm wheel 4014. When the robot is placed on the upper side of the base frame 1, the worm 4015 can be rotated, so that the worm 4015 drives the worm wheel 4014 and the bidirectional lead screw 4011 to rotate. The worm 4015 and the worm wheel 4014 can prevent the bidirectional lead screw 4011 from reversing. At the same time, the feeding is more accurate. The synchronous approach component 401 includes a bidirectional screw 4011 that is rotatably connected to the inner wall of the base frame 1. The adjacent ends of the two side push frames 2 are provided with mounting grooves 4013. The inner walls of the two mounting grooves 4013 are fixedly connected with nuts 4012. The two nuts 4012 are threadedly connected to the surface of the bidirectional screw 4011. The two ends of the bidirectional screw 4011 are movable and pass through the side ends of the two side push frames 2. When the bidirectional screw 4011 rotates, the surface of the bidirectional screw 4011 has two opposite directions. When the two-way screw 4011 rotates, it drives the two nuts 4012 and the two side push frames 2 to approach each other and fit against the surface of the robot. The stabilizing assembly 402 is provided with two groups. Each group of stabilizing assembly 402 includes a stabilizing groove 4024 opened on one side of the side push frame 2. The side end of the base frame 1 is fixedly connected with a stabilizing rod 4022. The stabilizing rod 4022 slides with the inner wall of the stabilizing groove 4024. When the two-way screw 4011 rotates to drive the side push frame 2 to move, the side push frame 2 is easy to tilt. When the side push frame 2 moves, The stabilizing rod 4022 is driven to slide on the inner wall of the stabilizing groove 4024, so that the side push frame 2 is not prone to skewing when moving. A limiting groove 4021 is provided at the side end of the stabilizing groove 4024, and the side end of the stabilizing rod 4022 is fixedly connected to the limiting block 4023. The limiting block 4023 slides with the inner wall of the limiting groove 4021. When the side push frame 2 moves, the stabilizing rod 4022 is easily pulled out. At this time, the limiting block 4023 moves on the inner wall of the limiting groove 4021 to limit it, so that the stabilizing rod 4022 will not be pulled out.
[0025] like Figure 2As shown, there are two groups of elastic fitting components 5, each group of elastic fitting components 5 includes a spring 501 fixedly connected to the inner wall of the side push frame 2, one end of the spring 501 is fixedly connected to the fitting plate 503, when the side push frame 2 is pushed to move, the side push frame 2 pushes the spring 501 and the fitting plate 503 to fit the two sides of the robot, elastically fitting the two sides of the robot to increase the fitting effect, the inner wall of the side push frame 2 is fixedly connected to the telescopic rod 502, one end of the telescopic rod 502 is fixedly connected to the fitting plate 503, The spring 501 is sleeved on the circumferential surface of the telescopic rod 502. When the spring 501 pushes the fitting plate 503 to fit the robot, the spring 501 is prone to lateral elastic deformation and damage. The telescopic rod 502 supports the spring 501, making it less likely for the spring 501 to undergo lateral elastic deformation. Two mutually parallel blocking plates 6 are fixedly connected to the upper end of the base frame 1. The two blocking plates 6 are respectively aligned with the two sides of the base frame 1 at their far ends. The blocking plates 6 can shield the front and rear sides of the robot to prevent it from falling off.
[0026] When the present invention is in use, when the robot is placed and moved conveniently by using this device, the robot is placed on the upper side of the base frame 1, and then the worm 4015 is rotated, so that the worm 4015 drives the worm wheel 4014 and the bidirectional screw 4011 to rotate. When the bidirectional screw 4011 rotates, it drives the two nuts 4012 and the two side push frames 2 to approach each other and fit against the surface of the robot. At this time, the side push frames 2 push the springs 501 and the fitting plates 503 to fit against the two sides of the robot, and elastically fit the two sides of the robot for fixation. At this time, the fixation is completed, the placement is more stable, and the fitting effect is better.
[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
