Description

Technical Field

[0001] The utility model relates to the technical field of robot wheel mounting structures, and specifically relates to a wheel mounting structure and a robot. Background Technique

[0002] The wheeled inspection robot is based on a wheeled traveling mechanism, combined with a variety of sensors, machine vision, navigation, and behavior planning technologies, etc., to achieve autonomous inspection, monitoring, and data transmission. It is mainly used for round-the-clock uninterrupted patrols in complex environments, promptly discovering abnormal situations and issuing alarms.

[0003] Currently, the patent with the patent authorization announcement number CN219687221U discloses a wheeled inspection robot, including a transfer vehicle body. One side of the top of the transfer vehicle body is fixedly installed with a pan-tilt, and a symmetrically arranged camera is fixedly installed on the top of the pan-tilt. An auxiliary mechanism for cooperating with the camera is arranged on the pan-tilt; the auxiliary mechanism includes an L-shaped plate, the L-shaped plate is slidably connected to the pan-tilt, and a U-shaped transparent plate for cooperating with the camera is fixedly installed on one side of the L-shaped plate; through the setting and use of the auxiliary mechanism, the lens of the camera can be shielded and protected, so that the phenomenon that the camera lens is damaged by being hit by an external object can be avoided. And in rainy and snowy weather, it can drive the cleaning plate to do reciprocating motion, so that the rain and snow attached to the U-shaped transparent plate near the camera lens can be effectively scraped off, and further the phenomenon that the camera vision is blocked by rain and snow can be avoided, and further the normal development of the inspection operation can be guaranteed.

[0004] Although the robot in the above patent can avoid the phenomenon that the camera vision is blocked by rain and snow and further guarantee the normal development of the inspection operation, there are still certain defects:

[0005] During the use of the tire, it will experience wear (especially in complex or harsh environments, such as uneven roads, dusty, humid or corrosive environments, etc.), which will lead to a decrease in the tire's grip, increase the risk of slipping, and may even cause safety problems. Therefore, in order to ensure the safe, stable, and efficient operation of the robot, the tires of the robot are generally replaced regularly. At present, most of the tires of the robot are installed and fixed by bolts. However, when the tire is fixed by bolts, a suitable tool is required to tighten it. If the operation is improper, the bolt may be loosened or damaged. And if the bolt is not tightened in place or loosens during use, the tire may fall off, thus triggering a safety accident. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a wheel mounting structure to solve the problems raised in the background technique, making the installation of the tires of the robot body simpler and more convenient, and not prone to detachment.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A wheel mounting structure includes an axle connected to a robot main body. A tire is provided at one end of the axle away from the robot main body. A clamping block is fixedly connected to one side of the tire close to the axle. A clamping groove is formed at one end of the axle away from the robot main body. The clamping groove matches the clamping block. A limiting component is connected to one side of the tire away from the axle.

[0008] Further, the limiting component includes a connecting plate and two inserting blocks. The two inserting blocks are respectively fixedly connected to both ends of the connecting plate. Through grooves matching the inserting blocks are formed at both the upper and lower ends of the tire. A slot matching the inserting block is formed at one end of the axle away from the robot main body.

[0009] Further, a receiving groove is formed at one end of the clamping block away from the axle. An anti - detachment block is slidably connected in the receiving groove. The connecting plate is fixedly connected to one end of the anti - detachment block away from the axle.

[0010] Further, an elastic member is sleeved outside the anti - detachment block. One end of the elastic member is fixedly connected to the receiving groove, and the other end of the elastic member is fixedly connected to the anti - detachment block.

[0011] Further, chamfers are formed on the circumferential sides of the inserting blocks near the axle.

[0012] Further, a grip is fixedly connected to one side of the connecting plate away from the axle.

[0013] Another object of the present utility model is to provide a robot, which includes a robot main body and also includes the above - mentioned wheel mounting structure. Its tire installation is simpler and more convenient, and it is not easy to become detached.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] For this kind of wheel mounting structure and robot, when installing the tire, only need to insert the clamping block into the clamping groove and rotate the clamping block so that the clamping block is perpendicular to the end of the clamping groove close to the tire. Then, the limiting component is used to limit the positions of the tire and the axle. In this way, the position change between the tire and the axle can be avoided. The installation process does not require additional tools, is simpler and easier to operate, and the tire is not easy to detach from the axle. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figures 1-5 , a wheel mounting structure, including an axle 2 connected to the robot main body 1. A tire 3 is provided at one end of the axle 2 away from the robot main body 1. A card block 6 is fixedly connected to one side of the tire 3 close to the axle 2. A card slot 4 is opened at one end of the axle 2 away from the robot main body 1. The card slot 4 matches the card block 6. A limiting component is connected to one side of the tire 3 away from the axle 2.

[0024] In the wheel mounting structure of the present utility model, when the tire 3 is installed, only need to insert the card block 6 into the card slot 4 and rotate the card block 6 so that the card block 6 is perpendicular to one end of the card slot 4 close to the tire 3, so as to prevent the tire 3 from detaching from the axle 2. Then, the limiting component is used to limit the positions of the tire 3 and the axle 2 to prevent relative rotation between the tire 3 and the axle 2, thereby preventing the card block 6 from detaching from the card slot 4. In this way, the connection between the tire 3 and the axle 2 can be made more stable, making the tire 3 not easily detach from the axle 2. Moreover, the installation process of the tire 3 does not require the use of additional tools, which is simpler and easier to operate. In addition, the existing technology of the robot main body 1 in the present utility model has a structure similar to that of a wheeled inspection robot structure disclosed in the patent with the patent authorization announcement number CN219687221U, so no more elaboration will be made here.

[0025] As Figures 2 to 5 shown, the limiting component includes a connecting plate 11 and two insert blocks 12. The two insert blocks 12 are respectively fixedly connected to both ends of the connecting plate 11. Through grooves 8 matching the insert blocks 12 are opened at both the upper and lower ends of the tire 3. An insert slot 5 matching the insert blocks 12 is opened at one end of the axle 2 away from the robot main body 1.

[0026] As Figure 2 and Figure 5As shown, a receiving groove 7 is formed at one end of the clamping block 6 away from the axle 2. A anti - detachment block 10 is slidably connected in the receiving groove 7, and a connecting plate 11 is fixedly connected to one end of the anti - detachment block 10 away from the axle 2.

[0027] As Figure 2 shown, an elastic member 9 is sleeved outside the anti - detachment block 10. One end of the elastic member 9 is fixedly connected to the receiving groove 7, and the other end of the elastic member 9 is fixedly connected to the anti - detachment block 10.

[0028] Specifically, when restricting the tire 3, it is only necessary to insert the plug 12 into the slot 5 from the position of the through - slot 8. After the plug 12 is inserted into the slot 5, the elastic member 9 will push the anti - detachment block 10 towards the axle 2, making it difficult for the plug 12 to detach from the slot 5 by itself, thus improving the stability of the connection between the axle 2 and the tire 3.

[0029] As Figure 5 shown, chamfers are provided on the circumferential side of the plug 12 near the axle 2. The chamfers play a guiding role, making it easier for the plug 12 to be inserted into the through - slot 8 and the slot 5.

[0030] As Figure 5 shown, a grip 13 is fixedly connected to the side of the connecting plate 11 away from the axle 2. When it is necessary to pull out the plug 12 from the slot 5, the plug 12 can be pulled out by grasping the grip 13. Without the grip 13, there is no grasping point on the surface of the plug 12, making it difficult to be pulled out.

[0031] A robot includes a robot main body 1 and also includes the above - mentioned wheel mounting structure.

[0032] Specifically, when replacing the tire 3 of the robot main body 1, it is only necessary to pull out the plug 12 from the slot 5, then rotate the tire 3 to align the clamping block 6 with the end of the clamping groove 4 near the tire 3, then pull out the old tire 3, then insert the clamping block 6 on the new tire 3 into the clamping groove 4, rotate the tire 3 to align the through - slot 8 with the slot 5, and then insert the plug 12 into the slot 5. The entire replacement process does not require the use of additional tools for assistance, and as long as the plug 12 is inserted into the slot 5, it can ensure that the tire 3 will not detach from the axle 2, making the connection between the tire 3 and the axle 2 more stable.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
