Abstract
Description
Technical Field
[0001] This utility model belongs to the field of robot equipment technology, specifically relating to a dual-wheel transmission structure for a robot. Background Technology
[0002] The mobile robot boasts an adorable design and a wealth of sensors, enabling a wide range of entertainment scenarios and competitions. Its dual-wheel drive system achieves stable autonomous movement and flexible motion control. Through coordinated dual-wheel transmission, it ensures efficient power output while utilizing differential speed principles to perform complex maneuvers such as turning and rotating in place, thus enhancing its mobility.
[0003] In existing technologies, the dual-wheel drive structure of robots often separates the driving and heat dissipation functions, requiring an additional heat dissipation power source. This increases the energy consumption and overall size of the equipment, and also easily leads to structural redundancy. In addition, in scenarios such as downhill where braking devices need to be used for a long time, the braking components lack targeted cooling design, and are prone to overheating after long-term high-intensity work, directly affecting braking accuracy and service life. Furthermore, the traditional air intake and exhaust channel design is crude, with low airflow circulation efficiency, making it difficult to meet the requirements of long-term stable operation of robots. To solve the above problems, a dual-wheel drive structure for robots is needed. Utility Model Content
[0004] The purpose of this utility model is to provide a simple and reasonably designed dual-wheel transmission structure for a robot in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions: A dual-wheel drive structure for a robot includes a housing. Dual-axis motors are fixedly mounted on both sides of the housing's interior. A cooling assembly is located on the inner side of the housing, and a drive heat dissipation assembly is located on the outer side of the housing. Wheels are mounted on both sides of the housing. The drive heat dissipation assembly includes a gear one fixedly connected to the output end of one side of the dual-axis motor. A rotating shaft is rotatably connected to both sides of the housing. A gear two, meshing with the outer side of the gear one, is fixedly sleeved on the outer side of the rotating shaft. Fan blades, located inside the wheels, are fixedly sleeved on the outer side of the rotating shaft.
[0006] As a further optimization of this utility model, the outer side of the wheel is provided with multiple exhaust holes, the two sides of the outer shell are provided with multiple exhaust holes, and the upper side of the outer shell is provided with an air inlet.
[0007] As a further optimization of this utility model, the cooling assembly includes a brake disc fixedly connected to the output end of the other side of the dual-axis motor, a circuit board fixedly disposed on the upper side of the dual-axis motor on the inner side of the housing, and an electric caliper that cooperates with the two brake discs respectively fixedly disposed on the lower side of the circuit board.
[0008] As a further optimization of this utility model, an air intake pipe is fixedly inserted through the front side of the outer shell, and the shape of the air intake pipe is hourglass-shaped.
[0009] As a further optimization of this utility model, an exhaust pipe is fixedly inserted through the rear side of the outer shell, and the exhaust pipe is connected to the air inlet.
[0010] As a further optimization of this utility model, a filter screen is fixedly installed on the inner side of the air intake pipe and a filter screen is fixedly installed on the inner side of the exhaust pipe.
[0011] The beneficial effects of this utility model are as follows: 1. This utility model uses a dual-axis motor to drive gear one to rotate, which meshes with gear two and the rotating shaft to rotate, synchronously driving the fan blades to rotate. This allows airflow to enter the interior through the air inlet and air inlet pipe of the outer casing, and then be discharged from the exhaust holes of the outer casing and wheel through the action of the fan blades, forming a circulating airflow. This quickly reduces the temperature of internal components such as the dual-axis motor and circuit board, without the need for an additional power source.
[0012] 2. This utility model utilizes the hourglass-shaped air intake pipe that allows airflow to enter during robot movement, precisely cooling the brake disc and electric caliper. Some of the airflow accelerates internal circulation, and the airflow is eventually discharged, assisting in the heat dissipation of internal components. The hourglass-shaped pipe has a narrow tube effect, increasing the airflow velocity and thus cooling the braking system. Attached Figure Description

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0016] Example: Figure 1 , Figure 3 As shown, a dual-wheel drive structure for a robot includes a housing 1, which protects the internal components and provides an installation environment for subsequent parts. Dual-axis motors 3 are fixedly mounted on both sides of the interior of the housing 1. The dual-axis motors 3 in this invention are model FF130-6V-10000RPM, which can be replaced according to actual needs. The dual-axis motors 3 are the power core of the entire structure. A drive and heat dissipation assembly 4 is provided on the outer side of the housing 1, enabling simultaneous power transmission and temperature control. Wheels 6 are provided on both sides of the housing 1, serving as the basic components for robot movement. The drive and heat dissipation assembly 4 encloses… The device includes a gear 401, which drives the subsequent parts to rotate. One output end of the dual-shaft motor 3 is fixedly connected to the inside of the gear 401. Both sides of the housing 1 are rotatably connected to a shaft 402, which provides the mounting base for the subsequent parts. A gear 403 is fixedly sleeved on the outside of the shaft 402. The gear 403 cooperates with the gear 401 to drive the wheel 6 to rotate. The outside of the gear 403 meshes with the outside of the gear 401. A fan blade 404 is fixedly sleeved on the outside of the shaft 402. The fan blade 404 accelerates the airflow inside the housing 1. The fan blade 404 is located inside the wheel 6.
[0017] like Figure 3 As shown, multiple exhaust holes 405 are provided on the outer side of the wheel 6. The exhaust holes 405 provide a channel for the hot airflow inside the outer shell 1 to be discharged. A dust cover is provided inside the exhaust holes 405. Multiple exhaust holes 405 are provided on both sides of the outer shell 1. An air inlet 406 is provided on the upper side of the outer shell 1. A dust cover is provided inside the air inlet 406. The air inlet 406 is used to introduce external cold air.
[0018] like Figure 1 , Figure 2 , Figure 4 As shown, a cooling assembly 5 is provided on the inner side of the outer shell 1. The cooling assembly 5 is designed to enhance the cooling of the braking components. The cooling assembly 5 includes a brake disc 501, which is a braking component. The output end of the dual-axis motor 3 is fixedly connected to the inner side of the brake disc 501. A circuit board 2 is fixedly provided on the inner side of the outer shell 1. The upper side of the circuit board 2 is provided with a control module and other electronic components for controlling the internal components of the robot. This is existing technology and will not be described in detail. The outer side of the dual-axis motor 3 is located on the lower side of the circuit board 2. Electric calipers 502, which cooperate with the two brake discs 501 respectively, are fixedly provided on the lower side of the circuit board 2. The electric calipers 502 cooperate with the brake discs 501 to provide the robot with deceleration, braking, and control of the speed difference between the two wheels 6.
[0019] like Figure 4As shown, an air intake pipe 503 is fixedly installed through the front side of the outer casing 1. The air intake pipe 503 is a channel for air to enter the interior. The shape of the air intake pipe 503 is hourglass-shaped, which increases the airflow velocity. An exhaust pipe 504 is fixedly installed through the rear side of the outer casing 1. The exhaust pipe 504 is mainly used to exhaust the air that enters through the air intake pipe 503. The exhaust pipe 504 is connected to the air intake hole 406. A filter screen 505 is fixedly installed on the inner side of the air intake pipe 503. The filter screen 505 prevents damage to internal parts caused by the intrusion of foreign objects. A filter screen 505 is fixedly installed on the inner side of the exhaust pipe 504.
[0020] It should be noted that in the use of this robot's dual-wheel transmission structure, the dual-axis motor 3 drives the first gear 401 to rotate, which in turn drives the second gear 403 to rotate, and simultaneously drives the fan blades 404 and cooling components 5 on the rotating shaft 402 to rotate. The rotation of the fan blades 404 causes the airflow that enters the interior of the outer casing 1 through the air inlet 406 and the exhaust pipe 504 to be discharged from the exhaust port 405, thereby reducing the temperature of the internal parts.
[0021] When it is necessary to cool down the brake disc 501 and electric caliper 502, a large amount of airflow enters the interior of the outer shell 1 through the air intake pipe 503 during the robot's movement. The air intake pipe 503 is hourglass-shaped. When the air flows through the air intake pipe 503, the flow velocity increases in the narrow throat. After cooling down the electric caliper 502 and brake disc 501 at the air outlet of the air intake pipe 503, most of the airflow is directly discharged from the filter screen 505. At the same time, the airflow velocity inside the outer shell 1 is accelerated, which speeds up the cooling of the internal parts.
[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
