Description

Technical Field

[0002] In automated production line material handling systems, the chassis drive unit is a core component of transport vehicles such as automated guided vehicles (AGVs) and rail shuttles (RGVs), and its clutch performance directly determines the transport efficiency and system flexibility.

[0003] Based on the above, the inventors have discovered that existing chassis drive devices often have some shortcomings. For example, the clutch structure design of some devices is not reasonable enough, and clutch instability is prone to occur during frequent starts and stops, resulting in large fluctuations in the operating speed of the transport vehicle and affecting the accuracy of material transportation. Moreover, the braking mechanism of some drive devices has a slow response speed, and cannot stop in time when emergency braking is required, increasing safety hazards. In addition, traditional devices have poor adaptability to different working conditions and are difficult to meet diverse production needs. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a chassis clutch drive device, aiming to achieve a more practical purpose.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] Please see Figures 1-4 A chassis clutch drive device includes a base frame 1. A front mounting seat 2 and a rear mounting seat 3 are fixedly mounted at both ends of the base frame 1. Universal wheels 4 are fixedly mounted at both ends of the bottom of the front mounting seat 2. A rotating shaft 5 is rotatably mounted at the bottom of the rear mounting seat 3. Drive wheels 6 are fixedly connected to both ends of the rotating shaft 5. A servo motor 7 is mounted on the top of the rear mounting seat 3. A transmission mechanism 8 is provided between the output shaft of the servo motor 7 and the rotating shaft 5. A braking mechanism 9 is provided at the end of the rear mounting seat 3 away from the base frame 1.

[0035] See Figure 2 and Figure 3The transmission mechanism 8 includes a drive sprocket 801, a driven sprocket 802, and a chain 803. The drive sprocket 801 is connected to the output shaft end of the servo motor 7 by a key. The driven sprocket 802 is fixed to the outer periphery of one end of the rotating shaft 5. The drive sprocket 801 and the driven sprocket 802 are connected by the chain 803. In use, the specific transmission mechanism 8 is used so that the combination of the drive sprocket 801, the driven sprocket 802, and the chain 803 can achieve efficient power transmission under the drive of the servo motor 7, ensuring stable rotation of the drive wheel 6 and improving transportation efficiency.

[0036] See Figure 4 The braking mechanism 9 includes a mounting bracket 901 fixed to one end of the rear mounting seat 3. Two guide rods 902 are vertically fixed between the top and bottom inner walls of the mounting bracket 901, and a cross frame 903 is slidably sleeved between the two guide rods 902. Both ends of the cross frame 903 extend outward, and a brake block 904 is fixedly connected to the bottom of the extended end of the cross frame 903. A cylinder 905 is vertically mounted on the top of the mounting bracket 901, and the output end of the cylinder 905 is fixedly connected to the top of the cross frame 903. In use, the unique design of the braking mechanism 9, including the coordinated work of the mounting bracket 901, guide rods 902, cross frame 903, brake block 904 and cylinder 905, makes the braking response rapid and reliable, effectively ensuring the safety of the transportation process.

[0037] See Figure 2 and Figure 3 Two symmetrical bearing seats 10 are fixedly installed at the bottom of the rear mounting base 3, and the rotating shaft 5 is rotatably mounted at the bottom of the rear mounting base 3 through the bearing seats 10.

[0038] See Figure 4 Guide holes are provided at the top of both ends of the cross frame 903, and the inner sidewall of the guide hole is slidably connected to the outer periphery of the corresponding guide rod 902. In use, the guide rod 902 and the guide hole work together to limit the position of the brake block 904 when the cross frame 903 drives it to adjust its position, thus avoiding position deviation and improving braking stability.

[0039] In use: By employing a specific transmission mechanism 8, such as a combination of a drive sprocket 801, a driven sprocket 802, and a chain 803, the servo motor 7 drives the drive sprocket 801 to rotate. Under the transmission of the chain 803 and the driven sprocket 802, efficient power transmission is achieved, ensuring stable rotation of the drive wheel 6 and improving transportation efficiency. The unique design of the braking mechanism 9, including the coordinated work of the mounting bracket 901, guide rod 902, crossbeam 903, brake block 904, and cylinder 905, allows the cylinder 905 to output power when braking is required, driving the brake blocks 904 at both ends of the crossbeam 903 to move downwards along the direction of the guide rod 902. This causes the brake blocks 904 to contact and rub against the ground, achieving braking. This results in rapid and reliable braking response, effectively ensuring the safety of the transportation process. Furthermore, the device has a compact structure and a reasonable layout of components, adapting to different working environments and conditions, greatly improving the system's flexibility.
