Description

Technical Field

[0001] The present invention belongs to the field of reconnaissance robots, and more specifically, it is an impact-resistant and shock-absorbing crawler drive wheel for a reconnaissance robot. Background Art

[0002] In military warfare, in order to gain the initiative in the war, it is necessary to understand information such as the military deployments and weaponry of the other side. At this time, it is often necessary to conduct reconnaissance on some hidden locations. Such reconnaissance tasks carry extremely high risks and constantly endanger the lives of reconnaissance personnel. With the continuous improvement of robot technology and the continuous expansion of its application fields, military reconnaissance robots have emerged and been put into actual combat. Using reconnaissance robots can help reconnaissance personnel complete high-risk reconnaissance work. Due to the particularity of the reconnaissance environment, the terrain is often complex and the environment is harsh. This poses very high requirements for the stability, strength, and flexibility of the robot. Therefore, it is necessary to develop a drive mechanism for a reconnaissance robot that is lightweight, high-strength, has good obstacle-crossing performance, and has impact-resistant and shock-absorbing properties. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an impact-resistant and shock-absorbing crawler drive wheel. This drive wheel can be used for a light crawler-type reconnaissance robot. The impact-resistant and shock-absorbing crawler drive wheel is made of polycarbonate material containing a polycarbonate-based high molecular polymer, and has characteristics such as high strength, elastic modulus, high impact strength, and high fatigue resistance. This drive wheel can absorb most of the impact energy when the robot is subjected to a large impact and during travel, protecting the robot from damage.

[0004] The technical solution adopted by the present invention is: an impact-resistant and shock-absorbing crawler drive wheel, which is composed of a crawler meshing tooth (1), a spoke (2), a shock-absorbing hole (3), a drive shaft fixing hole (4), and an anti-derailment groove (5); the crawler meshing teeth (1) are evenly distributed on the outermost circumference of the drive wheel and are used to mesh with the inner teeth of the crawler (6), and while driving the crawler to move, they can prevent slippage between the drive wheel and the crawler (6). The spoke (2) is a group of diamond-shaped spokes composed of two adjacent single spokes, and the middle of the diamond-shaped spokes is in a hollow shape. There are 12 groups of diamond-shaped spokes evenly distributed around the drive wheel, and the adjacent two groups of diamond-shaped spokes are not connected and are independently supported. When the drive wheel is subjected to a large impact or jolts during travel, the diamond-shaped spoke group will undergo a certain amount of deformation to absorb the impact energy.

[0005] There are a total of 12 shock-absorbing holes (3), which are evenly distributed between the spoke (2) and the drive shaft fixing hole (4), and their function is also to absorb the energy when the drive wheel is subjected to a large impact.

[0006] The anti - detachment belt groove (5) is located in the middle of the outer circumference of the driving wheel, dividing the crawler meshing teeth (1) into two parts. The anti - detachment belt groove (5) cooperates with the middle protruding part of the inner meshing teeth of the crawler (6). When the crawler (6) is tensioned in cooperation with the impact - resistant and shock - absorbing crawler driving wheel, the anti - detachment belt groove (5) can prevent the crawler (6) from detaching from the impact - resistant and shock - absorbing crawler driving wheel.

[0007] The drive shaft fixing hole (4) is located at the center of the circle of the impact - resistant and shock - absorbing crawler driving wheel and is used for cooperative installation with the drive shaft.

[0008] The beneficial effects of the present invention are as follows: The impact - resistant and shock - absorbing crawler driving wheel is made of polycarbonate containing a polycarbonate - based high - molecular polymer. This material has characteristics such as high strength and elastic modulus, high impact strength, and high fatigue resistance. The driving wheel adopts a diamond - shaped spoke design, which can absorb most of the impact energy when the robot is subjected to a large impact and during travel, protecting the robot from damage.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] As Figure 1 、 Figure 2 shown, an impact - resistant and shock - absorbing crawler driving wheel is composed of crawler meshing teeth (1), spokes (2), shock - absorbing holes (3), drive shaft fixing holes (4), and anti - detachment belt grooves (5); the crawler meshing teeth (1) are evenly distributed on the outermost circumference of the driving wheel and are used for meshing with the inner teeth of the crawler (6), which can prevent slippage between the driving wheel and the crawler (6) while driving the crawler to move.

[0014] As Figure 3 shown, the spoke (2) is a group of diamond - shaped spokes composed of two adjacent single spokes, and the middle of the diamond - shaped spokes is in a hollow shape. There are 12 groups of diamond - shaped spokes evenly distributed around the driving wheel, and the adjacent two groups of diamond - shaped spokes are not connected and are independently supported. When the driving wheel is subjected to a large impact or jolts during travel, the diamond - shaped spoke group will undergo a certain amount of deformation to absorb the impact energy.

[0015] There are a total of 12 shock-absorbing holes (3), which are evenly distributed between the wheel spoke (2) and the drive shaft fixing hole (4), and their function is also to absorb the energy when the driving wheel is subjected to a large impact.

[0016] The anti-derailment groove (5) is located in the middle of the outer circle of the driving wheel, dividing the crawler engaging teeth (1) into two parts. The anti-derailment groove (5) cooperates with the middle protruding part of the inner engaging teeth of the crawler belt (6). When the crawler belt (6) is tensioned in cooperation with the impact-resistant shock-absorbing crawler driving wheel, the anti-derailment groove (5) can prevent the crawler belt (6) from disengaging from the impact-resistant shock-absorbing crawler driving wheel.

[0017] The drive shaft fixing hole (4) is located at the center of the impact-resistant shock-absorbing crawler driving wheel and is used for mating installation with the drive shaft.
