Description

Technical Field

[0001] This utility model belongs to the field of electric tricycle handbrake technology, and in particular relates to a handbrake parking device for electric tricycles. Background Technology

[0002] Electric tricycles are three-wheeled transportation vehicles powered by batteries and driven by motors, used for hauling goods or people. Electric tricycles are characterized by their versatility, maneuverability, simple maintenance, convenient repair, and low price. They can easily navigate narrow roads. Electric tricycles have a reverse switch, allowing for convenient forward and reverse driving, which is very practical in narrow alleys and lanes. They are convenient for both driving and parking, and are widely used in short-distance transportation in households, urban and rural areas, individual rentals, factories, mines, sanitation, and community cleaning. The professional term for the handbrake is auxiliary brake. Unlike a standard brake, it uses a steel cable connected to the rear brake shoes to brake the vehicle.

[0003] Prolonged use of the handbrake can cause plastic deformation of the steel cable. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel. At this point, it is necessary to adjust the tension of the handbrake cable to ensure the parking effect of the handbrake. Therefore, a handbrake parking device for electric tricycles is needed. The device uses gears to drive a rack, which in turn drives the cable to tighten, thus adjusting the tension of the handbrake cable and ensuring the effectiveness of the handbrake. Utility Model Content

[0011] Preferably, a handle cover, which is a rubber sleeve, is attached to the surface of the control lever.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a rotating rod to drive a gear to rotate, and then the gear drives the handbrake cable to move upward in the inner cavity of the rectangular box through the rack, thereby tensioning the handbrake cable. The rotation of the rotating rod is locked in one direction by the engagement of the locking block and the ratchet. This achieves the purpose of adjusting the tension of the handbrake cable by moving the rack through the gear, and then the rack driving the cable to tighten, thus ensuring the effectiveness of the handbrake.

The handbrake cable 4 is fixedly connected to a rack 9, and the rotating rod 7 is fixedly connected to a ratchet 10. The rectangular box 5 is rotatably connected to a locking block 11 via a rotating shaft. The gear 8 and rack 9 mesh with each other. The end of the locking block 11 engages with the ratchet 10. The surface of the locking block 11 is fixedly connected to a connecting block 12. A spring 13 is fixedly connected between the connecting block 12 and the inner wall of the rectangular box 6. The right end of the rotating rod 7 is fixedly connected to a hand crank 14. The hand crank 14 increases the force-bearing surface at the end of the rotating rod 7, preventing slippage when directly rotating the rotating rod 7, thus making it easier for the user to rotate the rotating rod 7.

[0027] Example 2:

[0028] Figure 1-4This invention illustrates a handbrake parking device for an electric tricycle according to an embodiment of the present invention. It includes a handbrake frame 1; a rotating plate 2 is rotatably connected to the inner wall of the handbrake frame 1; a control lever 3 is mounted on the surface of the rotating plate 2; a handbrake cable 4 is wound around the surface of the rotating plate 2; a rectangular box 5 is integrally formed on the surface of the rotating plate 2; the handbrake cable 4 is slidably connected to the inner wall of the rectangular box 5; a rectangular box 6 is integrally formed on the surface of the rectangular box 5; a rotating rod 7 is inserted through the right side of the rectangular box 6; the left end of the rotating rod 7 penetrates the rectangular box 6 and extends into the inner cavity of the rectangular box 5, and is fixedly connected to a gear 8; a rack 9 is fixedly connected to the surface of the handbrake cable 4; a ratchet 10 is fixedly connected to the surface of the rotating rod 7; and the rectangular box 5... A locking block 11 is rotatably connected to the surface via a rotating shaft. A connecting block 12 is fixedly connected to the surface of the locking block 11. A spring 13 is fixedly connected between the connecting block 12 and the inner wall of the rectangular box 2 6. A limiting block 15 is integrally formed on the surface of the rotating plate 2. The limiting block 15 is located on the outside of the handbrake cable 4. By setting the limiting block 15, the winding of the handbrake cable 4 on the surface of the rotating plate 2 is limited, preventing the handbrake cable 4 from coming off the surface of the rotating plate 2, and effectively ensuring the stability of the position of the handbrake cable 4. A handle sleeve 16 is pasted on the surface of the control lever 3. The handle sleeve 16 is a rubber sleeve. By setting the handle sleeve 16, the friction of the surface of the control lever 3 is increased, preventing the hand from slipping when directly holding the control lever 3.

[0029] Working principle: When using this utility model, the user rotates the rotating rod 7 to drive the gear 8 to rotate. Then, the gear 8 drives the handbrake cable 4 to move upward in the inner cavity of the rectangular box 5 through the rack 9, thereby tensioning the handbrake cable 4. The spring 13 applies force to the connecting block 12, causing the connecting block 12 to drive the locking block 11 to engage with the ratchet 10. The engagement of the locking block 11 and the ratchet 10 provides one-way locking for the rotation of the rotating rod 7, ensuring the stability of the handbrake cable 4 after tensioning. This realizes that by driving the rack to move through the gear, and then the rack to tighten the cable, the tension of the handbrake cable can be adjusted, thereby ensuring the effectiveness of the handbrake.

[0030] In summary, this handbrake parking device for electric tricycles works by rotating the lever 7 to drive the gear 8, which in turn drives the handbrake cable 4 upward within the rectangular box 5 via the rack 9. This tensions the handbrake cable 4. Furthermore, the engagement of the locking block 11 and the ratchet 10 locks the rotation of the lever 7 in one direction. This allows the gear to drive the rack, which in turn tightens the cable, thus adjusting the tension of the handbrake cable and ensuring its effectiveness.
