[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-7 An electro-hydraulic braking device includes a base 2, which is hinged to a first vertical rod 26 and a second vertical rod 27 via a fourth rotating rod 29. A hydraulic cylinder 1 is fixed in the base 2, and a vertically arranged bracket 6 is provided between the hydraulic cylinder 1 and the first vertical rod 26. The bracket 6 is slidably arranged on the base 2.

[0020] A push rod 5 is fixed to the piston end of the hydraulic cylinder 1. A lever 4 is hinged to the upper side of the push rod 5. A sliding rod 9 is hinged to the inner side of the lever 4. The lower side of the sliding rod 9 is inserted into the bracket 6. A tension spring is provided between the sliding rod 9 and the bracket 6. A second vertical rod 27 is hinged to the inner side of the end of the lever 4. A screw 3 is provided between the first vertical rod 26 and the second vertical rod 27. One end of the screw 3 is hinged to the first vertical rod 26, and the other end of the screw 3 is hinged to the end of the lever 4.

[0021] Both the first vertical rod 26 and the second vertical rod 27 are provided with brake components arranged face to face. The brake components include a first brake component 10 and a second brake component 14 arranged vertically. The first brake component 10 and the second brake component 14 are hinged to the first vertical rod 26 or the second vertical rod 27.

[0022] Two sets of drive components are provided on the upper side of the base 2. Each set of drive components adjusts the angle of the brake of the first vertical rod 26 or the second vertical rod 27 respectively. The drive components include a motor 24 provided on the upper side of the base 2. The output end of the motor 24 is fixed with a first rotating rod 15. The end of the first rotating rod 15 is coaxially fixed with a worm gear 20. The worm gear 20 meshes with a worm wheel 28. The worm wheel 28 is fixed on a second rotating rod 18. The second rotating rod 18 is vertically arranged. A first driving bevel gear 11 is fixedly arranged above and a second driving bevel gear 19 is arranged below. The second driving bevel gear 19 meshes with the upper teeth of a second driven bevel gear 13. The second driven bevel gear 13 is coaxially fixed with a fifth rotating rod 12. One end of the fifth rotating rod 12 is fixedly connected with a second brake 14. The first driving bevel gear 11 meshes with the lower teeth of a first driven bevel gear 17. The first driven bevel gear 17 is coaxially fixed with a third rotating rod 16. One end of the third rotating rod 16 is fixedly connected with a first brake 10.

[0023] For stability, a rotating component 25 is fixed on the first vertical rod 26 or the second vertical rod 27. The rotating component 25 is hinged to the rotating rod 8. The axis of the third rotating rod 16 or the fifth rotating rod 12 coincides with the axis of the rotating rod 8.

[0024] The screw 3 includes a rod and threaded posts at both ends. The threaded posts are threadedly connected to the rod, and the threads of the two threaded posts are in opposite directions. When the rod rotates, the length of the screw 3 can be adjusted.

[0025] Working principle:

[0026] S1, No braking: When no braking is applied, the piston rod of the hydraulic cylinder 1 extends, the push rod 5 moves upward, and the push rod 5 moves to rotate the lever 4. During this process, the sliding rod 9 slides vertically with the bracket 6, and the tension spring inside is stretched. The rotation of the lever 4 drives the first vertical rod 26 and the second vertical rod 27 away from the braked part, thereby creating a gap between the braked part and the brake disc. The hydraulic brake is in the released state, and the device can operate normally at this time.

[0027] In this process, there is a four-bar linkage and a five-bar linkage. The four-bar linkage consists of: the hydraulic cylinder 1 and the base 2 as a whole as the first component, the push rod 5 as the second component, the lever 4 as the third component, and the second vertical rod 27 as the fourth component. When the push rod 5 moves upward (or in other words, the push rod 5 extends), the position of the lever 4 is unique, so the position of the second vertical rod 27 is also unique.

[0028] The five-bar linkage consists of: base 2 as the first component, first vertical bar 26 as the second component, screw 3 as the third component, lever 4 as the fourth component, and second vertical bar 27 as the fifth component. As mentioned above, the positions of lever 4 and second vertical bar 27 are unique, thus simplifying the five-bar linkage into a four-bar linkage. Therefore, the position of first vertical bar 26 is unique, allowing for non-braking.

[0029] S2. Braking Operation: When braking of the brake disc is required, the piston rod of hydraulic cylinder 1 retracts, and push rod 5 moves downward. As push rod 5 moves downward, since it is hinged to lever 4, it causes lever 4 to rotate around its connection point with the second vertical rod 27. The rotation of lever 4 causes the first vertical rod 26 and the second vertical rod 27 to rotate in opposite directions around the sixth rotating rod 29. As mentioned above, the positions of the first vertical rod 26 and the second vertical rod 27 are unique, thus applying uniform pressure to the brake disc, causing friction on the braked component and achieving braking. Sliding rod 9 and bracket 6 also reset.

[0030] During this process, braking can be achieved regardless of whether "sliding rod 9 and bracket 6" are present. If "sliding rod 9 and bracket 6" are present, the braking force can be increased under the action of the tension spring inside bracket 6, resulting in better braking.

[0031] S3. Perform "no braking" again. Refer to step S1. Under the pushing action of hydraulic cylinder 1, each component returns to its initial position and waits for the next braking operation.

[0032] S4. Adjust the angle between the first vertical rod 26 and the second vertical rod 27: When the rod rotates, the length of the screw 3 can be adjusted, which in turn adjusts the angle between the first vertical rod 26 and the second vertical rod 27, providing convenience for installation, etc.

[0033] S5. Adjustment of Brake Angle: When it is necessary to adjust the angle of the first brake 10 and the second brake 14, the motor 24 is started as a power source. Its output end drives the first rotating rod 15 to rotate. The worm 20 at the end of the first rotating rod 15 rotates accordingly. The rotation of the worm 20 drives the worm wheel 28 to rotate. The worm wheel 28 coaxially drives the second rotating rod 18 to rotate. The rotation of the second rotating rod 18 drives the first driving bevel gear 11 and the second driving bevel gear 19 to rotate. The first driving bevel gear 11 and the second driving bevel gear 19 drive the first driven bevel gear 17 and the second driven bevel gear 13 to rotate in the opposite direction. The first driven bevel gear 17 and the second driven bevel gear 13 drive the third rotating rod 16 and the fifth rotating rod 12 to rotate in the opposite direction as well. This causes the first brake 10 and the second brake 14 to rotate in the opposite direction, either moving away from or closer to each other. This achieves the adjustment of the angle of the first brake 10 and the second brake 14, enabling specific steering actions and thus achieving the steering function.

[0034] The beneficial effects of this utility model are:

[0035] 1. In use, the drive assembly of this utility model includes multiple rotating rods, bevel gears and other structures. Driven by a motor and through a series of gear transmissions, the angles of the first and second brake components can be flexibly adjusted according to actual braking requirements to adapt to diverse braking scenarios.

[0036] 2. In use, the first vertical rod and the second vertical rod are symmetrically arranged about the base. This symmetrical structure helps to distribute the force evenly on both sides of the brake disc during braking, avoiding problems such as uneven wear of the brake disc due to uneven force, thereby improving the smoothness of braking and the service life of the braking components, and ensuring the consistency of braking effect.

It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
