[0045] Embodiment one

[0046] As shown in Figure 1 and Figure 3 , the present embodiment proposes a tow driving device based on a tow rope, which comprises:

[0047] The traction cable 1, the driving assembly 2, the guide assembly 3 and the traction plate 4, the traction cable 1 is used for sleeving on the driving assembly 2 and the guide assembly 3, the driving assembly 2 can drive the traction cable 1 to move around the guide assembly 3;

[0048] The traction plate 4 is placed on the traction cable 1, the traction cable 1 comprises a traction part 11 and a supporting part, the traction part 11 is connected with the traction plate 4, and the supporting part is used for supporting the traction plate 4; during the movement of the driving assembly 2 driving the traction cable 1, the traction part 11 can drive the traction plate 4 to move;

[0049] The buffer module 5 is located between the driving assembly 2 and the guide assembly 3 and below the traction cable 1; a first guide groove (not shown in the figure) in an arc-shaped structure is formed on the side of the buffer module 5 close to the traction cable 1, the first guide groove is used for placing the traction cable 1, and the traction cable 1 can move in the first guide groove, so as to limit the rotation angle of the traction cable 1, so that the driving assembly 2 can change the moving direction of the traction plate 4 when the traction plate 4 passes through the buffer module 5 by driving the traction part 11 to drive the traction plate 4.

[0050] As shown in Figure 1 , the use process of the utility model is as follows: the target object (not shown in the figure) is placed on the traction plate 4, the driving assembly 2 drives the traction cable 1 to move, the traction part 11 drives the traction plate 4 to move, and then drives the target object on the traction plate 4 to move, the traction plate 4 moves according to the laying direction of the traction cable 1, and the shape and placement position of the buffer module 5 are selected according to actual needs, as shown in Figure 1 , during the rear-end collision test, the solid arrow is the moving direction of the traction plate 4, and the dotted arrow is the moving direction of the collision vehicle (not shown in the figure), first, the driving assembly 2 drives the traction cable 1 to move, the traction part 11 drives the traction plate 4 to move, at this time, the moving directions of the traction cables 1 on both sides of the traction plate 4 are opposite, when the traction plate 4 and the collision vehicle reach the preset speed, the two collide, and at the same time, the driving assembly 2 stops driving the traction cable 1, due to inertia, the traction plate 4 will continue to move, if the traction plate 4 stops moving without moving to the buffer module 5, the experiment is stopped; if the traction plate 4 moves to the buffer module 5, the buffer module 5 will make the traction plate 4 unable to move towards the driving assembly 2, thereby protecting the driving assembly 2 from being damaged by the collision of the traction plate 4, and reducing the maintenance cost of the traction driving device.

[0051] The traction driving device comprises a buffer module 5, and a first guide groove with an arc structure is formed on the buffer module 5 to limit the rotation angle of the traction cable 1. Since the first guide groove limits the rotation angle of the traction cable 1, the traction cable 1 is prevented from being excessively deformed or damaged under complex working conditions, and the safety and reliability of the traction driving device are improved. The traction part 11 and the support part 12 of the traction cable 1 respectively undertake the functions of connecting the traction plate 4 and supporting the traction plate 4, thereby ensuring the stability of the traction plate 4 during movement. In addition, the guiding effect of the buffer module 5 on the traction cable 1 further limits the risk of misalignment of the traction cable 1, so that the entire traction process is more stable and reliable.

[0052] In other embodiments, different buffer modules 5 can be selected according to the moving direction of the traction plate 4 during the traction process to increase the flexibility of the traction device.

[0053] To realize the stable connection between the traction part 11 and the traction plate 4, the present embodiment preferably comprises a fixing assembly 9, as shown in Figure 3 The fixing assembly 9 is used to be clamped below the traction part 11 and above the traction plate 4, so that the traction part 11 can be connected with the traction plate 4, and the traction part 11 can drive the traction plate 4 to move.

[0054] In the present embodiment, the fixing assembly 9 comprises a first magnet and a second magnet. The first magnet is located below the traction part 11, and the second magnet is located above the traction plate 4. The first magnet and the second magnet can attract each other, so that the traction part 11 and the traction plate 4 can be stably connected.

[0055] Preferably, the guide assembly 3 has the same structure as the driving assembly 2, so that the moving speed of the traction cable 1 or the traction plate 4 can be accurately controlled during the traction process. If the driving assembly 2 is damaged, it does not affect the normal use of the traction driving device, thereby increasing the stability and integrity of the traction driving device.

[0056] As shown in Figure 2 In the present embodiment, the driving assembly 2 comprises a driving piece 21, a gear assembly 22 and a transmission belt 23. The driving piece 21 is connected with the gear assembly 22 through the transmission belt 23. The traction cable 1 is sleeved on the gear assembly 22. The driving piece 21 can drive the transmission belt 23, thereby driving the gear assembly 22 to rotate and driving the traction cable 1 to move.

[0057] The driving member 21 is connected with the gear assembly 22 through the transmission belt 23, and the power of the driving member 21 is transmitted to the traction rope 1 by using the high efficiency and accuracy of gear transmission, thereby significantly improving the power transmission efficiency, ensuring that the traction rope 1 can smoothly and efficiently drive the traction plate 4 to move in the moving process, reducing energy loss and improving the operation efficiency of the whole device. The transmission is carried out through the gear assembly 22, and since the gear transmission has a fixed transmission ratio, the accuracy of the movement speed and direction of the traction rope 1 can be ensured, so that the traction plate 4 will not appear shaking or jamming phenomenon in the moving process. The driving member 21 and the gear assembly 22 are connected through the transmission belt 23, so that the structure of the whole driving device is more simple and clear, which is not only convenient for installation and debugging, but also convenient for adjusting the tension of the transmission belt 23 in the running process, thereby prolonging the service life of the transmission belt 23 and the gear and reducing the maintenance cost.

[0058] In the embodiment, the connection part of the traction rope 1 and the traction plate 4 is the traction part 11, the part supporting the traction plate 4 is the supporting part 12, and the traction part 11 and the supporting part 12 are an integral whole, that is, the traction rope 1.

[0059] As shown in Figure 2 In the embodiment, the gear assembly 22 includes a first gear 221 and a second gear 222, the first gear 221 and the second gear 222 are coaxially connected, the traction rope 1 is sleeved on the second gear 222, the first gear 221 is drivingly connected with the transmission belt 23, the transmission belt 23 can drive the first gear 221 to rotate, the rotation of the first gear 221 can drive the coaxial rotation of the second gear 222, and then drive the traction rope 1 to move.

[0060] The coaxial connection design of the first gear 221 and the second gear 222 ensures the accuracy and stability of power transmission, the first gear 221 is driven through the transmission belt 23, can efficiently transmit power to the second gear 222, and then drive the traction rope 1 to move, so that the movement of the traction rope 1 is more stable, and the moving speed and direction of the traction plate 4 can be accurately controlled to meet the high-precision requirement in complex test scenarios.

[0061] In the embodiment, sawteeth are formed on the traction rope 1 (not shown in the figure), the sawteeth can be engaged with the second gear 222 to drive the traction part 11 to move in the rotation process of the second gear 222.

[0062] The sawtooth on the traction cable 1 is engaged with the second gear 222, so that the power transmission between the traction cable 1 and the gear is more direct and efficient, avoiding the slippage phenomenon that may occur in the traditional transmission mode, ensuring that the traction cable 1 can stably and efficiently transmit power during driving, thereby improving the operation efficiency of the entire traction device; at the same time, since the engagement transmission of the sawtooth and the second gear 222 has the characteristics of high precision and low error, the movement of the traction cable 1 is more stable, thereby enabling the traction plate 4 to maintain an accurate trajectory and speed during movement.

[0063] In the embodiment, the driving assembly 2 further includes a tensioning assembly 24, which is connected to the second gear 222 through the traction cable 1.

[0064] As shown in Figure 2 , the tensioning assembly 24 can increase the wrap angle of the traction cable 1 on the second gear 222, so that the second gear 222 can move the traction cable 1 more labor-saving during movement, thereby optimizing the force transmission efficiency.

[0065] As shown in Figure 2 , in the embodiment, the driving assembly 2 further includes a gas cylinder 25, which is drivingly connected to the tensioning assembly 24. The gas cylinder 25 can push the tensioning assembly 24 to move, so as to relax or tighten the traction cable 1.

[0066] The gas cylinder 25 is drivingly connected to the tensioning assembly 24. The driving assembly 2 pushes the tensioning assembly 24 so that the tensioning assembly 24 can approach or move away from the guide assembly 3, thereby relaxing or tightening the traction cable 1, improving the flexibility and stability of the traction device. When it is necessary to disassemble or set the traction cable 1, the tensioning assembly 24 adjusts the traction cable 1 to a relaxed state. When the traction cable 1 is set, the tensioning assembly 24 can adjust the traction cable 1 to a tightened state, so that the gear assembly 22 can drive the traction cable 1 to move.

[0067] In other embodiments, the number of gas cylinders 25 and tensioning assemblies 24 can be changed according to specific test scenarios.

[0068] As shown in Figure 3 , in the embodiment, a moving wheel 6 is further included, which is installed on the traction plate 4 and can drive the traction plate 4 to move relative to the ground. The moving wheel 6 is installed on the traction plate 4 and can drive the traction plate 1 to move relative to the ground, so that the driving assembly 2 can reduce energy loss during driving the traction plate 4 to move, thereby improving the energy conversion rate of the driving assembly 2.

[0069] As shown in Figure 1 and Figure 3 , in the embodiment, a plurality of support blocks 7 are further included, each of which is arranged along the laying direction of the traction cable 1 and located below the traction cable 1, for supporting the traction cable 1 and the traction plate 4.

[0070] Each support block 7 is arranged along the laying direction of the traction cable 1 and is located below the traction cable 1, and each support block 7 can support the traction cable 1 and the traction plate 4, so that, during movement of the traction plate 4 driven by the traction cable 1, the pressure of the traction plate 4 on the traction cable 1 can be distributed to each support block 7, so as to reduce the pressure on the traction cable 1, thereby increasing the service life of the traction cable 1 and saving costs.

[0071] As shown in Figure 3 In this embodiment, the side of each support block 7 in contact with the traction cable 1 is formed with a second guide groove 71, and the second guide groove 71 can be used to place the traction cable 1, and the traction cable 1 can move in the second guide groove 71, so as to prevent the traction cable 1 from being misaligned and causing problems.

[0072] The side of the support block 7 in contact with the traction cable 1 is formed with a second guide groove, so that the traction cable 1 can move along the second guide groove during movement. Due to the length of the traction cable 1, and the traction part 11 is not connected with the traction plate 4, the second guide groove can prevent the traction cable 1 from being misaligned or misaligned during movement, thereby ensuring the safety and stability of the traction device.

[0073] As shown in Figure 1 and Figure 3 In this embodiment, the counterweight 8 is connected with the driving assembly 2, which is used to increase the friction between the driving assembly 2 and the ground.

[0074] By increasing the counterweight 8, and the counterweight 8 is connected with the driving assembly 2, the friction between the driving assembly 2 and the ground is increased, which prevents the driving assembly 2 from being misaligned during driving, which changes the tightness of the traction cable 1, thereby causing the traction cable 1 to be unable to be driven by the driving assembly 2 during the experiment.

[0075] As shown in Figures 1 to 3As shown above, the usage process of this embodiment is as follows: First, the traction cable 1 is sleeved on the drive assembly 2 and the guide assembly 3. Each support block 7 is placed below the traction cable 1 along the laying direction of the traction cable 1. Then, the traction plate 4 is placed above the traction cable 1, and the traction part 11 of the traction cable 1 is connected to one side of the traction plate 4 so that the traction part 11 can pull the traction plate 4 to move. According to the movement path of the traction plate 4 during the traction process, the buffer module 5 is placed between the guide assembly 3 and the drive assembly 2 so that the traction plate 4 can stop moving towards the drive assembly 2 after colliding with the buffer module 5, thereby protecting the drive assembly 2 from being damaged by the impact of the traction plate 2. As for the drive assembly 2, the tensioning assembly 24 is first adjusted so that the traction cable 1 is sleeved on the tensioning assembly 24 and the gear assembly 22. The gear assembly 22, the transmission belt 23 and the drive component 21 are combined. Then, the position of the tensioning assembly 24 is adjusted by the cylinder 25 so that the traction cable 1 can be driven by the gear assembly 2.

[0076] Example 2

[0077] This embodiment is similar to Embodiment 1, and the same parts are described in Embodiment 1. The following description only focuses on the improved parts.

[0078] like Figure 4 As shown, during the side impact test, the solid arrows indicate the direction of movement of the traction plate 4, and the dashed arrows indicate the direction of movement of the collision vehicle (not shown in the figure). First, the drive assembly 2 drives the traction cable 1 to move, and the traction unit 11 drives the traction plate 4 to move. At this time, the traction cables 1 on both sides of the traction plate 4 move in opposite directions. When the traction plate 4 and the collision vehicle both reach the preset speed, they collide. At the same time, the drive assembly 2 stops driving the traction cable 1. Due to inertia, the traction plate 4 will continue to move. If the traction plate 4 stops moving before reaching the buffer module 5, the experiment will stop. If the traction plate 4 moves to the buffer module 5, the buffer module 5 will prevent the traction plate 4 from moving towards the drive assembly 2, thereby protecting the drive assembly 2 from being damaged by the collision of the traction plate 4 and reducing the maintenance cost of the traction drive device.

Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
