Description

Technical Field

[0001] This utility model relates to the field of tricycle braking technology, specifically a tricycle parking emergency brake disc device. Background Technology

[0002] As a common mode of transportation, the safety and reliability of the parking brake system are crucial for tricycles. Traditional tricycle parking brake systems often employ a handbrake structure, connected to a brake lever and brake cable or cable, and working in conjunction with a brake rocker arm to lock the rear wheel or drive shaft, thus achieving parking braking. However, this traditional parking brake method has some inherent problems and limitations.

[0003] Traditional tricycle parking brake systems often rely on a single braking control path, where the brake lever is directly connected to the rear wheel brake via a brake cable or wire rope. Over long-term use, this design can lead to reduced parking brake effectiveness or even failure due to wear, aging, and loosening of the cable or wire rope. If the parking brake system malfunctions, the tricycle may slip while parked due to external factors (such as slope or wind), posing a safety hazard to the vehicle and the surrounding environment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides a parking emergency brake disc device for a tricycle, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a parking emergency brake disc device for a tricycle, comprising a brake disc base plate, a brake rocker arm plate rotatably connected to the brake disc base plate, an emergency brake bracket, and a parking brake handbrake cable. The emergency brake bracket is fixedly connected to the brake disc base plate, and the emergency brake bracket and the brake rocker arm plate are respectively disposed on opposite sides of the outer end face of the brake disc base plate. The emergency brake bracket has a through hole, and the brake rocker arm plate has a fixing hole. One end of the parking brake handbrake cable passes through the fixing hole and is fixedly connected thereto, and the other end of the parking brake handbrake cable passes through the through hole and is connected to the parking brake system of the tricycle.

[0008] Preferably, the emergency brake bracket is bent into an "L" shape, and two through holes are formed on the side of the emergency brake bracket parallel to the brake disc base plate. A pin is inserted through the opening to connect the emergency brake bracket and the brake disc base plate. The through hole is formed on the side of the emergency brake bracket perpendicular to the brake disc base plate, and the through hole consists of a circular hole and a rectangular hole connected together. The rectangular hole is formed at the outer edge of the through hole and passes through the through hole.

[0009] In a further preferred embodiment, the diameter of the parking brake cable is adapted to the diameter of the rectangular hole in the through hole, and the diameter of the parking brake cable is smaller than the diameter of the circular hole in the through hole.

[0010] (III) Beneficial Effects

[0011] Compared with the prior art, this utility model provides a parking emergency brake disc device for tricycles, which has the following beneficial effects:

[0012] In this utility model, the emergency parking brake disc device for tricycles adds an emergency brake bracket and a parking brake handbrake cable to the original brake disc base plate, which are connected to the brake rocker arm pads. This allows the user to separate the parking brake system from the original handbrake system when parking, thus effectively reducing fatigue of the original handbrake system, increasing parking safety, and improving the user experience.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 and Figure 2 An emergency parking brake disc device for a tricycle includes a brake disc base plate 1, a brake rocker arm 3 rotatably connected to the brake disc base plate 1, an emergency brake bracket 2, and a parking brake cable 4. The emergency brake bracket 2 is fixedly connected to the brake disc base plate 1, and the emergency brake bracket 2 and the brake rocker arm 3 are respectively disposed on opposite sides of the outer end face of the brake disc base plate 1. A through hole 21 is formed on the emergency brake bracket 2, and a fixing hole 31 is formed on the brake rocker arm 3. One end of the parking brake cable 4 passes through the fixing hole 31 and is fixedly connected thereto, while the other end of the parking brake cable 4 passes through the through hole 21 and is connected to the parking brake system of the tricycle. The parking brake system of the tricycle can adopt existing structures such as brake levers, allowing the parking brake cable 4 to be controlled from the grip position of the tricycle.

[0019] See Figure 3 The emergency brake bracket 2 is bent into an "L" shape, and two through holes are formed on the side of the emergency brake bracket 2 parallel to the brake disc base plate 1; a through hole 21 is formed on the side of the emergency brake bracket 2 perpendicular to the brake disc base plate 1. A pin is inserted through the opening to connect the emergency brake bracket 2 and the brake disc base plate 1. The through hole 21 consists of a circular hole and a rectangular hole that pass through the through hole 21. The rectangular hole is formed at the outer edge of the through hole 21 and passes through the through hole 21. The diameter of the parking brake cable 4 is matched with the diameter of the rectangular hole in the through hole 21, and the diameter of the parking brake cable 4 is smaller than the diameter of the circular hole in the through hole 21, so that the parking brake cable 4 can be pushed from the rectangular hole in the through hole 21 into the circular hole in the through hole 21. The emergency brake bracket 2 can be used to provide auxiliary support for the parking brake cable 4 and guide its passage.

[0020] When using this tricycle parking emergency brake disc device, the user's parking brake can be separated from the original handbrake system, allowing for independent use of the parking brake system. This effectively reduces fatigue of the original handbrake system, increases parking safety, and improves the user experience.
