Abstract
Description
Technical Field
[0001] This utility model relates to the field of robot vehicle technology, and in particular to an anti-collision device for robot vehicles. Background Technology
[0002] In modern logistics and industrial production, transport robots are widely used. They can efficiently and accurately move goods in various environments, greatly improving production and logistics efficiency. However, during operation, transport robots inevitably face the risk of collision.
[0003] To protect the safety of robotic vehicles, anti-collision devices are often installed around them. These devices use anti-collision strips to contact objects and reduce the risk of collisions. However, in current technology, these anti-collision strips are generally fixed to the anti-collision devices with bolts. After prolonged use, these strips often need to be replaced, requiring the removal and replacement of all bolts. This process involves installing and removing a large number of bolts each time, which takes a lot of time and is not conducive to replacing the anti-collision strips. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a collision avoidance device for robot vehicles, which solves the aforementioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A collision avoidance device for a robot vehicle includes a robot vehicle body. A mounting frame is fixedly installed around the robot vehicle body. A collision avoidance plate is fixedly installed on the surface of the mounting frame. A slot is formed at the top of the collision avoidance plate, and an insert plate is inserted into the slot. A collision avoidance strip is fixedly installed on the surface of the insert plate. A first limiting groove is formed on the surface of the insert plate. A first fixing plate is fixedly installed on the surface of the mounting frame. A first limiting plate is slidably connected inside the first fixing plate. A first elastic component is provided on the surface of the first limiting plate and is connected to the first fixing plate. A second limiting groove and a third limiting groove are formed at the top of the first limiting plate. A second elastic component is provided on the surface of the mounting frame. A second fixing plate is fixedly installed on the surface of the mounting frame. A second limiting plate is slidably connected inside the second fixing plate. A second elastic component is provided on the surface of the second limiting plate and is connected to the second fixing plate.
[0006] Preferably, the first elastic component includes a first connecting plate disposed on the surface of the first limiting plate, a first spring fixedly mounted on the surface of the first connecting plate, and the first spring being fixedly connected to the first fixing plate.
[0007] Preferably, the second elastic component includes a second connecting plate disposed on the surface of the second limiting plate, and a second spring is fixedly installed at the bottom of the second connecting plate, and the second spring is fixedly connected to the second fixing plate.
[0008] Preferably, a first handle is fixedly installed on the surface of the first limiting plate, and the first handle is made of stainless steel.
[0009] Preferably, a second handle is fixedly installed on the top of the second limiting plate, and the second handle is made of stainless steel.
[0010] Preferably, the first limiting plate is slidably connected to the anti-collision plate, and the first limiting plate is inserted into the first limiting groove.
[0011] Preferably, the second limiting plate is inserted into the second limiting groove, and the second limiting plate is inserted into the third limiting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the anti-collision device for the robot car needs to be replaced, pulling the second handle and the second limiting plate upwards stretches the second elastic component, causing the second limiting plate to leave the second limiting groove. Pulling the first handle moves the first limiting plate towards the robot car body, stretching the first elastic component and separating the first limiting plate from the first limiting groove. Releasing the second handle causes the second limiting plate to move downwards and insert into the third limiting groove due to the reverse force generated by the stretching of the second elastic component. Then, the first handle can be released, and the insert plate can be pulled out of the slot, thus completing the removal of the anti-collision strip. A new anti-collision strip can then be installed. The insert plate is inserted into the slot. Pulling the second handle and the second limiting plate upwards stretches the second elastic component, causing the second limiting plate to leave the third limiting groove and releasing the first limiting plate. The reverse force generated by the first elastic component causes the first limiting plate to insert into the first limiting groove, limiting the insert plate. Finally, releasing the second handle causes the reverse force generated by the stretching of the second elastic component to insert the second limiting plate into the second limiting groove, limiting the first limiting plate. Simply pulling the handle and releasing the limiting plate allows for quick disassembly or installation, significantly reducing operation steps and time. It completely eliminates the need for screwdrivers and other tools required for bolt disassembly and assembly, allowing for operation by hand. The double limiting protection prevents the anti-collision strip from falling off. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example: Refer to Figures 1-4A collision avoidance device for a robot car includes a robot car body 1. A mounting frame 2 is fixedly installed around the robot car body 1. A collision avoidance plate 3 is fixedly installed on the surface of the mounting frame 2. A slot 4 is formed at the top of the collision avoidance plate 3, and an insert plate 5 is inserted into the slot 4. A collision avoidance strip 6 is fixedly installed on the surface of the insert plate 5. A first limiting groove 7 is formed on the surface of the insert plate 5. A first fixing plate 8 is fixedly installed on the surface of the mounting frame 2. A first limiting plate 9 is slidably connected inside the first fixing plate 8. A first handle 12 is fixedly installed on the surface of the first limiting plate 9. The first handle 12 is made of stainless steel to facilitate better movement of the first limiting plate 9. A first elastic component is provided on the surface of the first limiting plate 9 and is connected to the first fixing plate 8. An elastic component includes a first connecting plate 10 disposed on the surface of a first limiting plate 9. A first spring 11 is fixedly mounted on the surface of the first connecting plate 10 and is fixedly connected to a first fixing plate 8. The first elastic component allows the first limiting plate 9 to be stably inserted into a first limiting groove 7, limiting the insertion plate 5. A second limiting groove 13 and a third limiting groove 14 are formed on the top of the first limiting plate 9. A second elastic component is disposed on the surface of the mounting bracket 2, and a second fixing plate 15 is fixedly mounted on the surface of the mounting bracket 2. A second limiting plate 16 is slidably connected inside the second fixing plate 15. A second handle 19 is fixedly mounted on the top of the second limiting plate 16. The second handle 19 is made of stainless steel, allowing the second limiting plate 16 to move more smoothly. The robot car uses an anti-collision device. When the anti-collision strip 6 needs to be replaced, pulling the second handle 19 and moving the second limit plate 16 upwards stretches the second elastic component, causing the second limit plate 16 to leave the second limit groove 13. Pulling the first handle 12 moves the first limit plate 9 towards the robot car body 1, stretching the first elastic component. The first limiting plate 9 separates from the first limiting groove 7. The second handle 19 is released, and the reverse force generated by the stretching of the second elastic component causes the second limiting plate 16 to move downwards and insert into the third limiting groove 14. Then, the first handle 12 can be released, and the insert plate 5 can be pulled out of the slot 4, thus completing the removal of the anti-collision strip 6. Next, the insert plate 5 on the new anti-collision strip 6 is inserted into the slot 4. Pulling the second handle 19 and the second limiting plate 16 upwards stretches the second elastic component, causing the second limiting plate 16 to leave the third limiting groove 14, thus releasing the restriction on the first limiting plate 9. The reverse force generated by the first elastic component causes the first limiting plate 9 to insert into the first limiting groove 7, restricting the insert plate 5. Finally, the second handle 19 is released.The reverse force generated by the stretching of the second elastic component causes the second limiting plate 16 to insert into the second limiting groove 13, thus limiting the first limiting plate 9. Disassembly or installation can be quickly completed by simply pulling the handle and releasing the limiting position, significantly reducing operation steps and time. It completely eliminates the need for screwdrivers and other tools required for bolt removal and assembly, allowing for operation by hand. Furthermore, the double limiting mechanism prevents the anti-collision strip 6 from falling off.
[0017] Specifically, the second elastic component includes a second connecting plate 17 disposed on the surface of the second limiting plate 16. A second spring 18 is fixedly installed at the bottom of the second connecting plate 17. The second spring 18 is fixedly connected to the second fixing plate 15. The second elastic component facilitates the second limiting plate 16 to be inserted into the second limiting groove 13 or the third limiting groove 14 more conveniently and stably. When inserted into the second limiting groove 13, it facilitates the limiting of the first limiting plate 9, thereby further limiting the insertion plate 5. When inserted into the third limiting groove 14, it limits the first limiting plate 9. Then the first handle 12 can be released, making it easier to replace the anti-collision strip 6.
[0018] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.
[0019] In use: When the anti-collision strip 6 needs to be replaced, pull the second handle 19 upwards to move the second limiting plate 16 and the second connecting plate 17 upwards, causing the second spring 18 to stretch and the second limiting plate 16 to leave the second limiting groove 13. Then pull the first handle 12 to move the first limiting plate 9 and the first connecting plate 10 towards the robot car body 1, causing the first spring 11 to stretch and the first limiting plate 9 to separate from the first limiting groove 7. After the first limiting plate 9 moves to the appropriate position, release the second handle 19. The reverse force generated by the stretching of the second spring 18 causes the second connecting plate 17 and the second limiting plate 16 to move downwards, causing the second limiting plate 16 to insert into the third limiting groove 14. Then release the first handle 12 and pull the insert plate 5 out of the slot 4 to complete the process. After disassembling the anti-collision strip 6, insert the insert plate 5 on the new anti-collision strip 6 into the slot 4. Then, pull the second handle 19 upward, causing the second limiting plate 16 and the second connecting plate 17 to move upward, which stretches the second spring 18 and causes the second limiting plate 16 to leave the third limiting groove 14, thus releasing the restriction on the first limiting plate 9. Then, the reverse force generated by the stretching of the first spring 11 causes the first connecting plate 10 and the first limiting plate 9 to move away from the robot car body 1, so that the first limiting plate 9 inserts into the first limiting groove 7 and restricts the insert plate 5. Finally, release the second handle 19, and the reverse force generated by the stretching of the second spring 18 causes the second connecting plate 17 and the second limiting plate 16 to move downward, so that the second limiting plate 16 inserts into the second limiting groove 13 and restricts the first limiting plate 9.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
