BACKGROUND
[0002] Vehicles such as, but not limited to, motorized scooters, motorcycles,
etc., have a plurality of components and assemblies, such as a body frame, a power
unit, a passenger seating area, a storage space, and a set of ground engaging members.
10 The power unit is adapted to provide the necessary power to the ground engaging
members, to drive the vehicle. The power unit, seating area, storage space, etc., are
all carried by the body frame. The ground engaging members are connected to the
body frame. Therefore, the body frame is designed to carry the load of the vehicle,
including the weight of the power unit, other components, and sub-assemblies of the
15 vehicle. Such weight carried by the body frame is transferred, through the ground
engaging members, to the ground.

20 to move between an open position (A) (as shown in Figure 5) and a primary latch
position (B) (as shown in Figure 6). The latching unit (354) in the open position (A)
acts as a stand. In the illustrated example, as shown in figure 5, the latching unit (354)
in the open position (A) acts as a stand for attachment structure (300).
[00065] As shown in figure 8, the latching unit (354) comprises an arm engaging
25 member (360), a rotating second arm member (362), and a connector arm member

engaging member (360) is coupled to the rotating second arm member (362). The
stand portion (368) is configured to engage a resting surface (for e.g., ground surface)
when the latching unit (354) is in the open position (A). The stand portion (368) acts
as a stand to the attachment structure (300). The latch receiving portion (364) is
20 disposed at substantially middle portion of the arm engaging member (360). The latch
receiving portion (364) is configured to engage the first latch member (352), when
the latching unit (354) is moved to a primary latching position (B). The latch receiving
portion (364) embodies a cut-out portion configured to receive the first latch member

frame (106) of the vehicle (100) is inserted into the attachment structure (300) such
that the first latch member (352) is positioned above the latching unit (354), thereafter
the latching unit (354) is moved from the open position (A) to the primary latch
5 position (B) by the push-pull mechanism. As the latching unit (354) moves towards
the primary latch position (B), the first latch member (352) is received by the latch
receiving portion (364) on the arm engaging member (360), thereby securing the first
latch member (352) and the arm engaging member (360). The first latch member
(352) secured to the arm engaging member (360) of the latching unit (354) by the
10 push-pull mechanism which holds the arm engaging member (360) in primary latch
position (B), thereby securing the first body frame (106) to the second body frame
(308). Thereby converting the modular vehicle (10) from two-wheeled configuration
to three-wheeled configuration.
[00069] In the illustrated example, only one latching mechanism (350) is
15 depicted. Alternatively, the modular vehicle (10) may include multiple latching
mechanisms (350) disposed on either side of the modular vehicle (10), without
limiting the scope of the invention.
[00070] Herein the above description of the invention only one control unit is
being used to control the operations of the modular vehicle (10), however multiple
20 control units in communication with one another may be used, without limiting the
scope of the invention.
[00071] Herein the above description, the fastening members may be nuts, bolts,
rivets etc., without limiting the scope of the invention.
[00072] Herein the above description, the coupling may be using fastening
25 members, welding, or any other coupling methods known in the art, without limiting
the scope of the invention.

[00073] The present disclosure discloses the modular vehicle (10) which can be
easily converted from a two wheeled vehicle to a three wheeled vehicle and vice versa
according to the requirements. The modular vehicle (10) comprises the latching
mechanism (350) which facilitates in detachably coupling the first body frame (106)
5 to the second body frame (308). The latching mechanism (350) simplifies the overall
process of changing of the modular vehicle (10) from the two wheeled configuration
to the three wheeled configuration thus a user can convert the vehicle from the two
wheeled configuration to the three wheeled configuration with ease and in cost
effective manner.

15 features of this disclosure, it will be appreciated that various modifications can be
made, and that many changes can be made in the preferred embodiments without
departing from the principles of the disclosure. These and other modifications in the
nature of the disclosure or the preferred embodiments will be apparent to those skilled
in the art from the disclosure herein, whereby it is to be distinctly understood that the
20 foregoing descriptive matter is to be interpreted merely as illustrative of the disclosure
and not as a limitation.
