Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle braking technology, specifically to a dual braking device for sanitation vehicles. Background Technology

[0002] The dual braking system is primarily used in sanitation vehicles to improve their safety and reliability, especially in complex urban road environments. However, existing dual braking systems are structurally complex, and the two braking methods may interfere with each other to some extent. This interference can lead to malfunctions in the braking system, thereby affecting the vehicle's safety and handling.

[0003] For example, Chinese patent document CN211893178U discloses a dual braking device. When the driver presses the pedal, the pin is at the limit position of the arc-shaped hole. When the pedal is pressed, the pedal pushes the master cylinder push rod through the pin to perform the main braking. However, since the pin is connected to the output end of the electric push rod, the movement of the pin will interfere with the electric push rod used for electronic braking. This can easily lead to abnormal operation of the braking device, affecting the safety and handling of the vehicle. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a dual braking device for sanitation vehicles, so as to solve the technical problem that the existing dual braking devices have complex structures and that the two braking methods may interfere with each other to some extent. This interference may cause the braking device to malfunction, thereby affecting the safety and handling of the vehicle.

[0005] This utility model is achieved through the following technical solution:

[0006] A dual braking device for sanitation vehicles includes a braking mechanism and a pedal. The working end of the braking mechanism has a connector. The pedal has a through hole, through which a connecting rod A is inserted. Both ends of the connecting rod A extend outward through the connector.

[0007] It also includes a connecting rod B, which has a radially through-hole in the connecting rod B. One end of the connecting rod A extends into the hole in the hole, and the end of the connecting rod B facing away from the braking mechanism is connected to a power source.

[0008] Furthermore, the pedal includes a pedal part for braking and a connecting part integrally formed with the pedal part, and the through hole is formed on the connecting part;

[0009] The end of the connecting part facing the connector and the top of the connecting part protrude outward to form protrusion A and protrusion B, respectively.

[0010] Furthermore, the through hole includes a horizontal groove and an arc groove communicating with the horizontal groove, the arc groove being closer to the foot pedal relative to the horizontal groove.

[0011] Furthermore, the diameter of the connecting rod A is smaller than the height of the through hole.

[0012] Furthermore, a pivot shaft for rotatably connecting the pedal to the frame is rotatably connected to the protrusion B, and the center of the pivot shaft coincides with the center of the arc groove.

[0013] Furthermore, the connecting rod A is threaded with multiple nuts to restrict the axial sliding of the connecting rod A from separating it from the connecting head.

[0014] The beneficial effects of this utility model are as follows:

[0015] When the driver presses the pedal of this utility model, the pedal swings and presses against the connector, thereby acting on the push rod of the braking mechanism to brake. Furthermore, when the pedal is pressed and swings, the through hole provides movement space for the connecting rod A, which can prevent the connecting rod A from interfering with the movement of the pedal when the pedal swings.

[0016] Secondly, when the connector is pressed down, the connector drives the connecting rod A to move synchronously. The connecting rod A moves in the through hole and the waist-shaped hole respectively, thereby avoiding interference with the individual use of the pedal and the power source when the connector is moved.

[0017] When the driver starts the power source via a button, the controller controls the power source to push the connecting rod B to move. When the connecting rod B moves, it acts on the connecting rod A, thereby pushing the connecting head to brake. When the connecting rod B pushes the connecting head, the connecting rod A slides in the through hole, providing movement space for the connecting rod A and preventing the movement of the connecting rod A from interfering with the pedal. This constitutes a dual braking system consisting of the pedal (main brake) and the power source (electronic brake). The braking device of this invention allows the sanitation vehicle to brake using another braking method when one braking method fails during driving, reducing the probability of accidents. Furthermore, the braking device of this invention has a simple structure, and both braking methods can achieve braking effects independently without interfering with each other during braking. This improves the service life of the braking device while ensuring the safety and maneuverability of the vehicle. Attached Figure Description

[0025] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Please see Figures 1 to 3 This utility model provides a technical solution: a dual braking device for sanitation vehicles. The braking device is installed on the vehicle frame and includes a braking mechanism 1 and a pedal 3. The braking mechanism 1 adopts the existing brake master cylinder and includes components such as piston, push rod and oil pipe. A connector 2 is fixedly connected to the push rod of the braking mechanism 1. The specific structure and working principle of the braking mechanism 1 are existing technologies and will not be described in detail here.

[0028] Please see Figure 1 and Figure 2Regarding the pedal 3, the pedal 3 includes a pedal part 31 for braking and a connecting part 32 integrally formed with the pedal part 31. The end of the connecting part 32 facing the connector 2 and the top of the connecting part 32 respectively protrude outward to form a protrusion A33 and a protrusion B34. The protrusion A33 abuts against the connector 2. A rotating shaft 8 for rotating the pedal 3 to the frame is rotatably connected to the protrusion B34.

[0029] Please see Figure 1 and Figure 3 The connecting part 32 has a through hole 4, which includes a horizontal groove 41 and an arc groove 42 communicating with the horizontal groove 41. The arc groove 42 is closer to the foot pedal part 31 than the horizontal groove 41, and the center of the rotating shaft 8 coincides with the center of the arc groove 42.

[0030] Please see Figure 1 and Figure 2 A connecting rod A5 is inserted through the through hole 4. The diameter of the connecting rod A5 is smaller than the height of the through hole 4, and both ends of the connecting rod A5 extend outward through the connecting head 2. Multiple nuts 9 are threaded onto the connecting rod A5 to restrict the axial sliding of the connecting rod A5 from separating it from the connecting head 2.

[0031] It also includes a connecting rod B6, on which a waist-shaped hole 61 is radially through. One end of the connecting rod A5 extends into the waist-shaped hole 61. The end of the connecting rod B6 away from the braking mechanism 1 is connected to a power source 7. The power source 7 can be an electric push rod or a hydraulic push rod in the prior art.

[0032] The working principle of this utility model is as follows: When the driver presses the pedal 3, the pedal 3 swings towards the connector 2 via the rotating shaft 8. At this time, the protrusion A33 presses against the connector 2, which in turn acts on the push rod of the braking mechanism 1. The push rod then transmits brake fluid through the oil pipe to the pistons of each brake caliper, which in turn pushes the brake shoes to open outward, causing friction between the brake pads and the inner surface of the brake drum, thereby achieving the braking effect. As for how the pedal 3 resets after use and other braking-related structures, these are existing technologies and are not the focus of this application. They will not be elaborated on in this application.

[0033] Furthermore, when the pedal 3 is pressed and swings, the connecting rod A5 is provided with movement space through the through hole 4, which can prevent the connecting rod A5 from interfering with the movement of the pedal 3 when the pedal 3 swings.

[0034] Secondly, when the connector 2 is pressed against the protrusion A33, the connector 2 drives the connecting rod A5 to move synchronously. The connecting rod A5 moves in the through hole 4 and the waist-shaped hole 61 respectively, thereby avoiding interference with the individual use of the pedal 3 and the power source 7 when the connector 2 is moved.

[0035] When the driver starts the power source 7 via a button, the controller controls the power source 7 to push the connecting rod B6 to move. When the connecting rod B6 moves, it acts on the connecting rod A5, thereby pushing the connecting head 2 to brake. When the connecting rod B6 pushes the connecting head 2, the connecting rod A5 slides in the horizontal groove 41, providing movement space for the connecting rod A5 and preventing the movement of the connecting rod A5 from interfering with the pedal 3. This constitutes a dual braking system consisting of the pedal 3 (main brake) and the power source 7 (electronic brake). The braking device of this utility model allows the sanitation vehicle to brake using another braking method when one braking method fails during driving, reducing the probability of accidents. Furthermore, the braking device of this utility model has a simple structure, and both braking methods can achieve braking effects independently without interfering with each other during braking. This improves the service life of the braking device while ensuring the safety and maneuverability of the vehicle.

[0036] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
