The present disclosure relates generally to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to an automatic and compact steering lock device for two-wheelers and/or three-wheelers.
TECHNICAL BACKGROUND
The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s).
In recent years the cost of motorcycles has increased substantially. In many instances, motorcycle can cost as much as an automobile. Therefore, it is important to provide means for reducing the potential for theft of such a vehicle. The most typical way of protecting a two-wheeler and/or three-wheeler against theft is using a large chain, which can be looped through one of the wheels and/or a portion of the frame and then extended about a stationary object, such as a tree or lamp post. In order to provide this capability, the chain has to be relatively long. Thus, it is very cumbersome to store. In addition, the links of the chain are readily exposed so that a thief with the proper equipment can cut through the links of the chain at a critical point and remove it from the motorcycle.
Another type of locking means is in the form of a U-shaped piece which has a straight cylinder extending across the open end of the U-shape. The typical U-shaped piece is also about a foot and a half in length and thus is also difficult to store. The U-shaped portion of the lock also extends through a wheel of the vehicle or motorcycle. It prevents theft by preventing complete rotation of the wheel in that it comes against the portion of the fork holding the wheel onto the motorcycle. However, the U-shaped piece can also be removed with metal cutting tools.
Vehicles are fitted with a steering lock device to prevent theft of the vehicle when the vehicle is parked. The steering lock device prevents movement of the handle of the vehicle preferably two wheelers and/or three-wheelers more than a pre-defined limit. However, such a steering lock device requires more mounting space and adds additional cost to the vehicle. The existing steering lock devices are not efficient enough to lock the handle of the vehicle and are not compact in nature.

Therefore, there is an immense need in the art of an automatic steering lock device having a compact size. More specifically, a steering lock device assembly providing a strong locking means to prevent rotation of the handle more than a pre-defined limit and at the same time requires less mounting space.

The reduction gear (22) is rotatably coupled to the bevel gear (21) of the transmission assembly (20). The reduction gear (22) is configured to reduce the number of revolutions per minute (rpm) at the output end of the reduction gear (22). The reduction gear (22) is engaged with the cam-ring gear (30) in order to facilitate rotary movement of the cam-ring gear (30) during locking/unlocking of the handlebar of the vehicle. The cam-ring gear (30) may be defined as an output gear that transforms rotary movement into reciprocating or linear movement of the slider (40).
Referring to FIG. 2 and FIG. 3, the cam ring gear (30) is defined with a center hole (31), an eccentric vertically extending member (32), at least two extrusions (33, 34) and a plurality of stoppers (35). The vertically extending member (32), the at least two extrusions (33, 34) and the plurality of stoppers (35) are integrally formed on an upper surface (30a) of the cam ring gear (30). Each extrusion of the at least two extrusions (33, 34) is defined having an arc shaped structure, but not limited to the same. The center hole (31) is provided to facilitate rotatory mounting of the cam ring gear (30) within the housing (101) of the device (100). The vertically extending member (32) is provided to transform rotary movement of the cam ring gear (30) into the reciprocating or linear movement of the slider (40) to facilitate locking/unlocking of the handlebar of the vehicle. The vertically extending member (32) is defined to have a cylindrical profile but not limited to the same. The at least two extrusions (33, 34) are provided to limit the excess linear movement of the slider (40) during excess movement of the cam-ring gear (30) due to momentum of the actuator (11). The first extrusion (33) is configured to prevent or limit linear movement of the slider (40) during locking operation of the device (100), as shown in FIG. 5b. The second extrusion (34) prevent or limit movement of the slider (40) during unlocking operation of the device (100), as shown in FIG. 6b. The plurality of stoppers (35) prevents mis-alignment of the cam ring gear (30) during operation of the device (100).

Referring to FIG. 4, the slider (40) is depicted comprising a proximal end (401) and a distal end (402), such that the proximal end (401) is defined as an end near to the housing (101) of the device (100) during locked position of the device (100). The distal end (402) is defined as an end opposite to the proximal end (401). The proximal end (401) is provided with a groove (42) configured to facilitate mounting of the locking pin (41). The distal end (402) is defined having a first slot (43) configured to receive the second extrusion (34), during unlocking operation of the device (100). The first slot (43) is defined having an arc shaped profile but not limited to the same. An intermediate portion (403) defined between the proximal end (401) and the distal end (402), such that the intermediate portion (403) is defined having a second slot (44) adapted to receive the vertically extending member (32) to facilitate linear movement of the slider (40). The second slot (44) is defined having a U-shaped profile to receive the vertically extending member (32) of the cam ring gear (30). Alternatively, the shape of the second slot (44) may vary depending on an outer profile of the vertically extending member (32).
In an embodiment of the present disclosure, the locking condition of the device (100) is described. Referring to FIG. 5a and FIG. 5b, as soon as the user rotates a key to lock the handlebar of the vehicle, a current is allowed to pass through the PCB assembly (50) from the battery to actuate the actuator (11). Alternatively, the user may press a switch mounted on the handle bar of the vehicle to allow flow of current from the battery to the actuator (11) through the PCB assembly (50). The actuator (11) starts to rotate in a clockwise direction transmitting the torque and/or power to the cam ring gear (30) through the bevel gear (21) and the reduction gear (22) of the transmission assembly (20). The cam ring gear (30) starts to rotate in a clockwise direction such that the vertically extending member (32) gets received inside the U-shaped slot (44) of the slider (40). The rotary movement of the vertically extending member (32) with the cam ring gear (30) exerts a push force on the slider (40) to facilitate linear movement of the slider (40) towards a side wall of the housing (101) of the device (100). The linear movement of the slider (40) facilitates linear movement of the locking pin (41) to get engaged with the handlebar and in turn lock the handlebar in a particular position. The excess movement of the slider (40) is prevented by the housing (101) as the proximal end (401) of the slider (40) abuts

against an inside surface of the side wall of the housing (101). Further, the linear movement of the slider (40) in direction opposite to the locking direction is prevented by the first extrusion (33), as the first extrusion (33) abuts with an outer surface of the slider (40) at the distal end (402), as shown in FIG. 5b.
In an embodiment of the present disclosure, the unlocking condition of the device (100) is described. Referring to FIG. 6a and FIG. 6b, when the user rotates the key or presses the switch to unlock the handlebar of the vehicle, a current with reverse polarity is allowed to pass through the PCB assembly (50) from the battery to actuate the actuator (11) in reverse direction. The rotation of the actuator (11) in reverse direction facilitates counter-clockwise rotation of the cam ring gear (30). Again, the vertically extending member (32) gets received inside the U-shaped slot (44) to facilitate linear movement of the slider (40) away from the housing (101) and in turn to disengage the locking pin (41) from the handlebar to unlock the vehicle. As soon as the locking pin (41) is disengaged the actuator (11) stops rotating. However, the momentum generated by the actuator (11) due to inertia of the rotating parts, the cam ring gear further rotates to some extent. In order prevent excess rotation of the slider (40), the second extrusion (34) gets received inside the arc-shaped slot (43) provided at the distal end (402) of the slider (40). The receiving of second extrusion (34) inside the arc-shaped slot (43) prevents excess linear movement of the slider (40) in backward direction. The provision of at least two extrusions (34, 34) and slots (43) in the slider (40) prevents excess movement of the slider (40) during locking/unlocking of the handlebar of the vehicle.
Referring to FIGs 7-9, an actuator stopping feedback mechanism of the device (100) is depicted. The slider (40) is provided with a carrier (45) configured to receive a spring (46) and a pair of moving terminals (47). The spring (46) is configured to bias the pair of moving terminals (47) in outward direction. The carrier (45) is fitted on an upper surface of the slider (40). The PCB assembly (50) comprises a circuit board (51), and a plurality of fixed terminals (52, 53, 54). The PCB assembly (50) is configured to govern the operation of the actuator (11) either in clockwise direction or in counter clockwise direction based on the driver's input and also to stop supply of the current to the actuator (11) as soon as the slider (40) has successfully attained the locked position or the unlocked position.

Referring to FIG. 10 and FIG. 11, the locked position of the slider (40) is shown with the actuator stopping feedback mechanism. When the slider (40) moves from the unlocked position to locked position, the pair of moving terminals (47) closes the circuit of first fixed terminal (52) with a second fixed terminal (53) after this the current supply to the actuator (11) is stopped. Similarly, when the slider (40) moves from the locked position to the unlocked position, the pair of moving terminals (47) closes the circuit of the first fixed terminal (52) with a third fixed terminal (54), after this the current supply to the actuator (11) is stopped. The moving terminals (47) provided on the slider (40) prevents excess rotation of the actuator (11) beyond the locked and/or unlocked position of the slider (40) by stopping the supply of current to the actuator (11) through the circuit board (51).
The automatic steering lock device in accordance with the present disclosure, provides a cost effective steering lock device. The steering lock device is formed to have a compact assembly to utilize minimum mounting space in the vehicle. The compact assembly of the steering lock device also reduces curb weight of the vehicle. The steering lock device in accordance with the present disclosure has long life cycle and less maintenance.
