Description

Technical Field

[0001] This utility model relates to the field of robot racing vehicle technology, specifically to a robot racing vehicle. Background Technology

[0002] Currently and in the future, different types of robots, such as industrial robots, service robots, and special-purpose robots, are playing an increasingly important role in human society. Some intelligent vehicles on the market are currently playing an important role in cultivating robot talents and conducting robot research experiments as robot learning and research platforms. Popularizing robot education is becoming increasingly important.

[0003] To stimulate children's learning motivation and creativity, and to cultivate a competitive spirit, various robot competitions at all levels have emerged. The engineering challenge in robot competitions simulates complex industrial scenarios, requiring robots to complete highly difficult tasks such as grasping and transportation.

[0004] However, existing robotic racing vehicles suffer from low efficiency and long processing times because they can only grab and transport one type of item to a designated area at a time. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this utility model proposes a robotic racing vehicle, including a hollow robotic vehicle body. A bottom turntable is rotatably connected to the top center of the robotic vehicle body. Several supports are evenly fixed on the upper surface of the bottom turntable. The supports are arranged in an array with the center of the bottom turntable as the center. A top turntable is fixed on the top of the supports. A first motor that drives the bottom turntable to rotate is fixed in the inner cavity of the robotic vehicle body. Each support is provided with a gripping component for grasping objects.

[0006] To achieve the above objectives, the main body of the robot car is used for transporting items. Since it is an existing structure, it will not be described in detail here. The gripping components grip the items to be transported for the competition. The first motor provides power to drive the bottom turntable, which is rotatably connected to the main body of the robot car and coaxially fixed with the output shaft of the first motor, to rotate. This, in turn, drives the support and top turntable, which are integrated with the bottom turntable, to rotate. This, in turn, drives several gripping components to rotate, enabling the simultaneous gripping of multiple items to be transported to the designated area, thereby improving the efficiency of item retrieval and shortening the time required for item retrieval and transportation.

[0007] Furthermore, the gripping assembly includes a support base, within which two upper and lower grippers are rotatably connected. Each upper gripper is located directly above an adjacent lower gripper, and each upper gripper is fixedly connected to its adjacent lower gripper via a plurality of evenly arranged connecting posts. One end of each upper and lower gripper extends out of the support base, and the ends of each upper and lower gripper extending out of the support base are fixedly connected via contact plates. The support base is equipped with a control assembly for controlling the rotation of the upper and lower grippers.

[0008] The above technical solution uses a support base to support the upper and lower jaws, and a control component to provide power to drive the two upper and two lower jaws to rotate, which in turn drives the two contact plates to rotate, thus realizing the function of picking up and putting down objects.

[0009] Furthermore, the control component includes an upper gear integrated with each upper jaw clamp, the upper gear being located within and rotatably connected to the support base, and two upper gears meshing with each other. Each lower jaw clamp has a lower gear integrated with it on the side away from the contact plate, the lower gear being located within and rotatably connected to the support base, each lower gear being located directly below an adjacent upper gear, and two lower gears meshing with each other. A power gear is also rotatably connected to the support base, the power gear meshing with one of the lower gears, and a second motor for driving the power gear to rotate is fixed on the support base.

[0010] Through the above technical solution, the second motor provides power to drive the power gear to rotate. The rotation of the power gear will drive one of the lower gears meshing with the power gear to rotate. Power is transmitted through the two lower gears and the two upper gears, driving the four upper and lower jaws to rotate, thereby realizing the function of picking up and putting down objects.

[0011] Furthermore, the support and the bearing seat are connected by a connecting assembly.

[0012] The above technical solution provides power through the connecting component, connecting the support and the bearing seat, making it convenient to adjust the position of the bearing seat.

[0013] Furthermore, the connecting assembly includes a rear mounting plate fixedly connected to the support. A first lug is fixed to the side of the rear mounting plate opposite to the support. Both sides of the first lug are hinged to L-shaped swing rods. A front mounting plate is fixed to one side of the support. A second lug is fixed to the side of the front mounting plate opposite to the support. The outer wall of the second lug is hinged to the bend of the adjacent swing rod. The ends of the two swing rods are fixedly connected by a long shaft. Both ends of the long shaft extend through the swing rods. Two oppositely arranged third lugs are fixed to the side of the rear mounting plate opposite to the support and located above the first lug. Each of the third lugs is hinged to a telescopic rod. The extended end of the telescopic rod is connected to the end of the long shaft that extends through the swing rod by a spring. A third motor for driving one of the swing rods to rotate is fixed to the first lug.

[0014] Through the above technical solution, the third motor provides power to drive the swing arm, which is fixed to the output shaft of the third motor and rotatably connected to the first ear seat, to rotate. The rotation of the swing arm will drive the second ear seat, which is hinged to the swing arm, to rotate, and then drive the support seat, which is fixed to the second ear seat, to rotate. This will drive the upper and lower jaw clamps to rotate. Through the cooperation of the spring, the long rod and the telescopic rod, the rotation of the front mounting plate is limited and connected.

[0015] Furthermore, the rear mounting plate is provided with an adjustment component to control the front mounting plate to always remain in a horizontal state.

[0016] By using the above technical solution and by setting an adjustment component, the front mounting plate and the support base are always kept in a horizontal state, thereby keeping the upper and lower jaws always in a horizontal state. This ensures that the clamped items are always horizontal and will not tip over. It can also clamp multiple stacked items at the same time, further improving the efficiency of picking up and transporting items.

[0017] Furthermore, the adjustment assembly includes a first sprocket disposed within and fixed to the first ear seat, a second sprocket fixed within the second ear seat, and a chain meshing with the first sprocket and the second sprocket.

[0018] With the above technical solution, the first sprocket always remains stationary, while the second lug and front mounting plate, which are integrated with the second sprocket, rotate relative to the rocker arm. When the rocker arm rotates, the second sprocket, the second lug, and the front mounting plate remain horizontal through the cooperation of the sprocket and the chain.

[0019] In summary, this robotic racing vehicle has the following beneficial effects:

[0020] The robot racing vehicle has an existing structure for transporting items, so it will not be described in detail here. It uses gripping components to grab the items to be transported in the competition. Powered by a first motor, it drives the bottom turntable, which is rotatably connected to the robot's main body and coaxially fixed with the output shaft of the first motor, to rotate. This, in turn, drives the support and top turntable, which are integrated with the bottom turntable, to rotate. This, in turn, drives several gripping components to rotate, enabling the simultaneous grabbing of multiple items to transport them to the designated area, thereby improving the efficiency of item retrieval and shortening the time required for item retrieval and transportation.

[0021] This robotic racing vehicle is powered by a connecting component that connects the support and the base, allowing for easy adjustment of the base's position. It is suitable for items of different heights, and the items are lifted off the ground during transport, reducing the possibility of damage.

[0022] This robotic racing vehicle, through the setting of adjustment components, ensures that the front mounting plate and support base are always in a horizontal state, thereby keeping the upper and lower grippers in a horizontal state. This ensures that the gripped items are always horizontal and will not tip over. It can also grip multiple stacked items at the same time, further improving the efficiency of picking and transporting items. Attached Figure Description

[0031] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0032] like Figure 1-6 As shown, the preferred embodiment of this utility model provides a robotic racing vehicle, comprising a hollow robotic body 1. A bottom turntable 2 is rotatably connected to the top center of the robotic body 1. Several supports 3 are evenly fixed on the upper surface of the bottom turntable 2, arranged in an array around the center of the bottom turntable 2. A top turntable 4 is fixed to the top of the supports 3. A first motor driving the bottom turntable 2 to rotate is fixed inside the robotic body 1. Each support 3 is equipped with a gripping component 5 for grasping items. The robotic body 1 is used for transporting items, which is an existing structure and will not be described in detail here. The gripping components 5 grasp the items to be transported for the competition. Power is provided by the first motor, which drives the bottom turntable 2, which is rotatably connected to the robotic body 1 and coaxially fixed with the output shaft of the first motor, to rotate. This, in turn, drives the supports 3 and the top turntable 4, which are integrated with the bottom turntable 2, to rotate, thereby driving the gripping components 5 to rotate. This enables the simultaneous grasping of multiple items for transport to a designated area, improving the efficiency of item retrieval and shortening the time spent on item retrieval and transportation.

[0033] like Figure 1 and Figure 2 and Figure 3 and Figure 6The gripping component 5 includes a support base 501. Two upper grippers 502 and lower grippers 503 are rotatably connected inside the support base 501. Each upper gripper 502 is located directly above the adjacent lower gripper 503. Each upper gripper 502 and the adjacent lower gripper 503 are fixedly connected by several evenly arranged connecting posts 504. One end of each upper gripper 502 and the lower gripper 503 extends out of the support base 501. The ends of each upper gripper 502 and the adjacent lower gripper 503 extending out of the support base 501 are fixedly connected by a contact plate 505. A rubber anti-slip sheet is fixed on the side of the contact plate 505 away from the upper gripper 502 and the lower gripper 503 to prevent slippage. The support base 501 is provided with a control component for controlling the rotation of the upper gripper 502 and the lower gripper 503.

[0034] like Figure 1 and Figure 2 and Figure 3 and Figure 6 The upper jaw 502 and the lower jaw 503 are supported by the support base 501. The control component provides power to drive the two upper jaws 502 and the two lower jaws 503 to rotate, which in turn drives the two contact plates 505 to rotate, so as to realize the function of picking up and putting down objects.

[0035] like Figure 1 and Figure 2 and Figure 3 and Figure 6 The control component includes an upper gear 506 integrated with each upper jaw 502. The upper gear 506 is located inside the support 501 and rotatably connected to the support 501. The two upper gears 506 mesh with each other. Each lower jaw 503 is located on the side away from the contact plate 505 and has a lower gear 507 integrated with it. The lower gear 507 is located inside the support 501 and rotatably connected to the support 501. Each lower gear 507 is located directly below the adjacent upper gear 506 and meshes with each other. A power gear 508 is also rotatably connected to the support 501. The power gear 508 meshes with one of the lower gears 507. A second motor 509 that drives the power gear 508 to rotate is fixed on the support 501.

[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 6 The second motor 509 provides power to drive the power gear 508 to rotate. The rotation of the power gear 508 will drive one of the lower gears 507 meshing with the power gear 508 to rotate. Power is transmitted through the two lower gears 507 and the two upper gears 506 to drive the four upper jaw grippers 502 and lower jaw grippers 503 to rotate, so as to realize the function of picking up and putting down objects.

[0037] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The support 3 and the support seat 501 are connected by the connecting component 6. The connecting component 6 provides power to connect the support 3 and the support seat 501, making it convenient to adjust the position of the support seat 501.

[0038] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The connecting assembly 6 includes a rear mounting plate 601 fixedly connected to the support 3. A first lug 602 is fixed to the side of the rear mounting plate 601 opposite to the support 3. Both sides of the first lug 602 are hinged to L-shaped swing rods 603. A front mounting plate 604 is fixed to one side of the support 501. A second lug 605 is fixed to the side of the front mounting plate 604 opposite to the support 501. The outer wall of the second lug 605 is hinged to the bend of the adjacent swing rod 603. The ends of the two swing rods 603 are connected through... The long shaft 606 is fixedly connected, and the two ends of the long shaft 606 extend through the swing rod 603. The rear mounting plate 601 is fixed with two oppositely arranged third ear seats 607 located above the first ear seat 602. Each third ear seat 607 is hinged to a telescopic rod 608. The extended end of the telescopic rod 608 is connected to the end of the long shaft 606 that extends through the swing rod 603 through a spring 609. A third motor that drives one of the swing rods 603 to rotate is fixed on the first ear seat 602.

[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 Power is provided by a third motor, which drives the swing arm 603, which is fixed to the output shaft of the third motor and rotatably connected to the first ear seat 602, to rotate. The rotation of the swing arm 603 drives the second ear seat 605, which is hinged to the swing arm 603, to rotate, which in turn drives the support seat 501, which is fixed to the second ear seat 605, to rotate. This causes the upper jaw clamp 502 and the lower jaw clamp 503 to rotate. Through the cooperation of the spring 609, the long rod and the telescopic rod 608, the rotation of the front mounting plate 604 is limited and connected.

[0040] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5The rear mounting plate 601 is equipped with an adjustment component 7 that controls the front mounting plate 604 to always remain in a horizontal state. By setting the adjustment component 7, the front mounting plate 604 and the support base 501 are always kept in a horizontal state, thereby keeping the upper jaw clamp 502 and the lower jaw clamp 503 always in a horizontal state. This ensures that the clamped items are always horizontal and will not tip over. It can also clamp multiple stacked items at the same time, further improving the efficiency of picking up and transporting items.

[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The adjustment assembly 7 includes a first sprocket 701 disposed in and fixed to the first ear seat 602, a second sprocket 702 fixed in the second ear seat 605, the rotation point of the second sprocket 702 being coaxially arranged with the connection point of the rocker arm 603, and a chain 703 meshing with the first sprocket 701 and the second sprocket 702 being sleeved on the first sprocket 701 and the second sprocket 702.

[0042] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The first sprocket 701 remains stationary. The second lug 605 and the front mounting plate 604, which are integrated with the second sprocket 702, rotate relative to the rocker arm 603. When the rocker arm 603 rotates, the second sprocket 702, the second lug 605 and the front mounting plate 604 remain horizontal through the cooperation of the sprocket and the chain 703.

[0043] When in use, the power is connected, the switch is turned on, and the operator controls the main body 1 of the machine to move to the location of the item. The third motor is turned on, and the power provided by the third motor drives the swing arm 603, which is fixed to the output shaft of the third motor, to rotate. The rotation of the swing arm 603 will drive the second ear seat 605, which is rotatably connected to the swing arm 603, to rotate, which in turn drives the front mounting plate 604, which is fixed to the second ear seat 605, to rotate. This, in turn, drives the support seat 501, which is an integral structure with the front mounting plate 604, to rotate. The support seat 501 rotates to the side of the item.

[0044] At this time, the second motor 509 is turned on, and the second motor 509 provides power to drive the power gear 508 to rotate. The rotation of the power gear 508 will drive one of the lower gears 507 that meshes with it to rotate. The rotation of one of the lower gears 507 will drive the other lower gear 507 that meshes with it to rotate. The rotation of the two lower gears 507 will drive the lower jaw clamp 503, which is integrated with the lower gear 507, to rotate. The rotation of the lower jaw clamp 503 will drive the upper jaw clamp 502, which is fixedly connected to the lower jaw clamp 503 through the connecting column 504, to rotate. The rotation of the upper jaw clamp 502 will drive the two meshing upper gears 506 to rotate, thereby realizing the grasping function and grasping the competition items.

[0045] Then, the third motor is turned on, which drives the swing arm 603 to reverse, thereby causing the upper jaw clamp 502 and the lower jaw clamp 503 to move upward. During the upward movement, the sprocket and chain 703 work together to keep the second sprocket 702, the second ear seat 605 and the front mounting plate 604 in a horizontal state, thereby keeping the upper jaw clamp 502, the lower jaw clamp 503 and the grasped item in a horizontal state.

[0046] Then turn on the first motor, which provides power to drive the bottom turntable 2, which is rotatably connected to the main body 1 of the robot and coaxially fixed with the output shaft of the first motor, to rotate. This in turn drives the support 3 and the top turntable 4, which are integrated with the bottom turntable 2, to rotate. This causes the other empty upper jaw 502 and lower jaw 503 to rotate to the competition item. Repeat the above operation to grab another competition item, thus realizing the function of grabbing multiple competition items and transporting them to the designated location at one time.

[0047] When there are more items than the number of upper jaw grippers 502 and lower jaw grippers 503, workers can also stack multiple regular items using upper jaw grippers 502 and lower jaw grippers 503, and then grab the item at the bottom, further improving transportation efficiency and shortening transportation time.

Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
