The following specification particularly describes the invention and the manner in which it is to be performed.
TECHNICAL FIELD
[0001] The present invention relates to a parking brake assembly for a vehicle. More particularly, the present invention relates to a parking brake assembly of a vehicle which can be operated by a foot of a user of the vehicle.
BACKGROUND
[0002] Parking brake systems are an essential component of a vehicle, which allows a user of the vehicle to securely park the vehicle in a stationary position. The parking brake systems are also used as emergency braking mechanisms in cases of brake failures or other emergencies. Some users also use the parking brake assembly to stabilise the vehicle while operating the same on the road with inclination and declination.
[0003] Conventional vehicles have the parking brake to be operated using a hand lever which is usually located near the driver’s seat. In a conventional 3-wheeled vehicle, for example, the hand-operated lever for the parking brake is located near the entry/exit gate or portion of the vehicle and/or on the floorboard of the vehicle, which causes issues in the ingress and egress of the user of the vehicle. For example in certain conventional vehicle layouts, when the parking brake lever is pulled to engage the parking brake, the parking brake lever may cause dig or poke into the legs of the user during operation or during ingress or egress. Further, as already mentioned, since the parking brake is also used during operation of the vehicle other than parking, the parking brake must be operated carefully while the vehicle is being operated. The hand operated parking brake lever near the floor makes this operation difficult and risky because it can be cumbersome to engage and disengage and may require the user of the vehicle to release the grip on the steering assembly of the vehicle. Further, the usage of such a parking brake by the user results in distraction to the user, and the user has to take their eyes off the road to enable and disable the parking brake, which results in a dangerous situation for the user as well as the public. Furthermore, the positioning of the hand lever may not be ergonomically optimal, and the user has to bend and engage the brake which causes discomfort to the user due to lack of space available in a vehicle to move freely. Additionally, the existence of such levers also creates design restrictions for the vehicle. The hand operated parking brake lever in conventional vehicle layouts are usually in a protruding configuration. This often cause obstructions in the access to some portions of the frame assembly of the vehicle such as design plates of the vehicle.
[0004] Thus, the conventional parking brake assemblies which are known in the art are not ergonomically optimal, create discomfort, cause issues in ingress/egress, are cumbersome to operate, create design restrictions, and hence are undesirable to the user of the vehicle.
[0005] Hence, there exists a need to provide an improved parking brake assembly, which can overcome all of the abovementioned problems and other problems of known art.
[0006] There is also a need to mount the parking brake assembly in an effective manner without compromising on the number of parts, and complexity of the parking brake, as well as increase ease of serviceability and assembly. Further, there is a need to identify a location for the parking brake which advantageously enables the driver to easily engage and disengage the brake without any distractions.
