Description

Technical Field

[0001] The utility model belongs to the field of electric tricycle pull rod brake devices, and particularly relates to a lubricating bearing pull rod brake device for an electric tricycle. Background Art

[0002] Electric tricycles with large capacity, deep discharge, and the ability to meet the continuous discharge requirements for long-term work are often commonly used transportation tools for modern people when pulling goods or people. The brake device used to stop or reduce speed is also an essential part of an electric tricycle.

[0003] Currently, the handbrake of existing electric tricycles is often installed on the outer shell of the electric tricycle. When the driver uses the handbrake for auxiliary braking, they need to change their sitting posture and stretch their arms outside to operate. Such a braking method has a relatively high risk.

[0004] Therefore, aiming at the problem that the handbrake of the existing electric tricycle is installed on the outer shell of the electric tricycle, when using the handbrake for auxiliary braking, it is necessary to stretch the arm out of the vehicle and change the sitting posture at the same time, with a relatively high risk coefficient. The existing electric tricycle brake device is improved by installing the handbrake and the foot brake together for convenient simultaneous operation to ensure the safety of the driver. Content of the Utility Model

[0005] In order to overcome the problem that the handbrake of the existing electric tricycle is installed on the outer shell of the electric tricycle, when using the handbrake for auxiliary braking, it is necessary to change the sitting posture and stretch the arm out of the vehicle.

[0006] The technical solution of the utility model is: a lubricating bearing pull rod brake device for an electric tricycle, which includes a mounting base, a foot brake pedal, an accelerator pedal, a foot brake stroke slot, a handbrake arm, and a handbrake lever; the foot brake pedal is movably connected to the mounting base installed in the cab of the electric tricycle, the accelerator pedal is movably connected to the mounting base and is located on the right side of the foot brake pedal, the foot brake pedal is provided with foot brake stroke slots arranged at equal intervals from top to bottom, the handbrake lever is installed on the mounting base and is located on the foot brake pedal, and the handbrake arm fixedly connected to the handbrake lever is matched with the foot brake stroke slot.

[0007] Preferably, by setting a handbrake lever above the foot brake pedal on the mounting base, the handbrake lever is movably connected to the mounting base. When stepping on the brake, rotate the handbrake lever, and fix it through the handbrake arm and the foot brake to form a slot to achieve assisted parking. With such a design, the driver does not need to change the posture and does not need to stretch the arm outside the electric tricycle to use the handbrake of the electric tricycle, solving the braking safety problem of the electric tricycle, improving the stability, and being convenient for the elderly to operate.

[0008] Preferably, an elastic rotating shaft movably connected to the mounting base is installed on the right side of the handbrake lever, and elastic rotating shafts movably connected to the mounting base are installed on the left sides of the foot brake pedal and the accelerator pedal. Under the action of an external force, the elastic rotating shaft can drive the foot brake pedal, the accelerator pedal and the handbrake pedal to rotate, and after the external force extrusion is lost, they will reset under the elastic action of the elastic rotating shaft.

[0009] Preferably, a brake conversion lubricating bearing is installed at the bottom end of the electric tricycle. A first mechanical pull rod is movably connected between the brake conversion lubricating bearing and the foot brake pedal. The rotation of the foot brake pedal drives the movement of the first mechanical pull rod, thereby driving the brake conversion lubricating bearing at the other end of the first mechanical pull rod to rotate accordingly.

[0010] Preferably, a second mechanical pull rod located at the bottom end of the electric tricycle is movably connected to one side of the brake conversion lubricating bearing. The right end of the second mechanical pull rod is fixedly connected to a brake head. After the foot brake pedal rotates, the first mechanical pull rod drives the brake conversion lubricating bearing to rotate, thereby driving the second mechanical pull rod to move.

[0011] Preferably, first elbows are fixedly connected to both ends of the first mechanical pull rod, and a second elbow is fixedly connected to the left end of the second mechanical pull rod. The designs of the first elbow and the second elbow enable the first mechanical pull rod and the second mechanical pull rod to be better fixed on the brake conversion lubricating bearing.

[0012] Preferably, two mechanical pull rod holes are provided on the brake conversion lubricating bearing. The first elbow and the second elbow are both inserted into the mechanical pull rod holes. The first elbow and the second elbow are movably connected to the brake conversion lubricating bearing by being inserted into the mechanical pull rod holes, and the brake conversion lubricating bearing can reduce the resistance of the foot brake pedal.

[0013] Preferably, the first elbow fixedly connected to the bottom end of the first mechanical pull rod is inserted into one of the mechanical pull rod holes, and the second elbow is inserted into the other mechanical pull rod hole. Two spare pull rod holes are provided on the brake conversion lubricating bearing. The spare pull rod holes can be used when the mechanical pull rod holes fail. Such a design extends the service life of the entire brake conversion lubricating bearing.

[0014] Advantages of the present utility model:

[0015] 1. By providing a handbrake lever above the foot brake pedal on the mounting base, the handbrake lever is movably connected to the mounting base. When stepping on the brake, rotate the handbrake lever and fix it through the card slot formed by the handbrake arm and the foot brake to achieve assisted parking. With such a design, the driver does not need to change the posture, nor does the driver need to stretch the arm outside the electric tricycle to use the handbrake of the electric tricycle, which solves the brake safety problem of the electric tricycle, improves the stability, and is convenient for the elderly to operate.

[0016] 2. The brake conversion lubricating bearing plays an essential role in connecting two mechanical pull rods. When the foot steps on the brake pedal, the front mechanical rod pulls the rear mechanical brake pull rod, and the brake conversion lubricating bearing starts to operate, reducing the force on the foot brake pedal and making it easier and safer for the legs to drive.

By setting a hand brake lever 6 above the foot brake pedal 2 on the mounting base 1, and the hand brake lever 6 is movably connected to the mounting base 1. When stepping on the brake, rotate the hand brake lever 6, and fix it through the hand brake arm 5 and the foot brake to form a slot, achieving assisted parking. With such a design, there is no need for the driver to change the posture, and there is no need for the driver to stretch the arm outside the electric tricycle to use the hand brake of the electric tricycle, solving the brake safety problem of the electric tricycle, improving the stability, and facilitating the operation of the elderly.

[0025] Please refer to Figures 1 - 3 , in this embodiment, an elastic rotating shaft movably connected to the mounting base 1 is installed on the right side of the hand brake lever 6, and elastic rotating shafts movably connected to the mounting base 1 are installed on the left sides of the foot brake pedal 2 and the accelerator pedal 3. A brake conversion lubricating bearing 7 is installed at the bottom end of the electric tricycle. A first mechanical pull rod 8 is movably connected between the brake conversion lubricating bearing 7 and the foot brake pedal 2. The elastic rotating shaft can drive the foot brake pedal 2, the accelerator pedal 3 and the hand brake pedal to rotate under the action of an external force, and will reset under the elastic action of the elastic rotating shaft after losing the external force extrusion. The rotation of the foot brake pedal 2 drives the movement of the first mechanical pull rod 8, thereby driving the brake conversion lubricating bearing 7 at the other end of the first mechanical pull rod 8 to rotate accordingly.

[0026] Please refer to Figure 1 , Figure 4 , Figure 5, in this embodiment, one side of the brake conversion lubricating bearing 7 is movably connected to the second mechanical pull rod 9 located at the bottom end of the electric tricycle.
