[0044] Figure 2A illustrates a left perspective view of the body frame (102), in accordance with an embodiment of the present invention. Figure 2B illustrates a left side view of the body frame (102) of Figure 2A, in accordance with an embodiment of the present invention. Figure 2C illustrates a right side view of the body frame (102) of Figure 2A, in accordance with an embodiment of the present invention. Figure 2D illustrates a top view of the body frame (102) of Figure 2A, in accordance with an embodiment of the present invention.

[0045] The body frame (102) includes a head tube (202) designed to pass through a steering member (not illustrated) of the steering assembly (104). A main frame (204) extends obliquely in a rearward and downward direction from the head tube (202) to a first cross frame (206) of the body frame (102). Specifically, a front end (208) of the main frame (204) is joined to an upper portion (210U) of the head tube (202), and an end portion (212) (illustrated, in Figure 2A) of the main frame (204) is joined to a middle part (214) (illustrated in Figure 2A) of the first cross frame (206). In a specific embodiment, the main frame (204) extending between the head tube (202) and the first cross frame (206) is formed as a substantial straight member. The first cross frame (206) extends along a vehicle width direction (W) (shown in Figure 2A) and is adapted to connect a first pivot frame (216L) and a second pivot frame (216R) of the body frame (102). In particular, the first cross frame (206) connects a top portion (218L) (illustrated in Figure 2B) of the first pivot frame (216L) and a top portion (218R) (illustrated in Figure 2C) of the second pivot frame (216R).

[0046] The body frame (102) further includes a down frame member (220). The down frame member (220) extends obliquely in the rearward and downward direction from a lower portion (210L) of the head tube (202) to a secondcross frame (222) of the body frame (102). In the case of the electric vehicle (100), the down frame member (220) can be designed to support the battery (120). The second cross frame (222) extends along the vehicle width direction (W) and is adapted to connect a bottom portion (224L) (illustrated in Figure 2B) of the first pivot frame (216L) and a bottom portion (224R) (illustrated in Figure 2C) of the second pivot frame (216R).

[0047] Further, a first seat rail member (226L) and a second seat rail member (226R) of the body frame (102) extend rearwardly from the main frame (204) towards the rear portion (122) of the vehicle (100). More specifically, the first seat rail member (226L) and the second seat rail member (226R) are extended from a substantial mid-portion (228) of the main frame (204) towards the rear portion (122) of the vehicle (100). In this configuration, the first seat rail member (226L) and the second seat rail member (226R) are fixedly joined to the substantial midportion (228) of the main frame (204) through a welded joint.

[0048] A first sub rail member (230L) of the body frame (102) extends in the rearward and upward direction from the first pivot frame (216L) towards the rear portion (122) of the vehicle (100). Likewise, a second sub rail member (230R) of the body frame (102) extends in the rearward and upward direction from the second pivot frame (216R) towards the rear portion (122) of the vehicle (100). At the rear portion (122), the first sub rail member (230L) is joined to the first seat rail member (226L), and the second sub rail member (230R) is joined to the second seat rail member (226R). In the illustrated configuration, a suitable permanent joining technique (e.g., welding) is used to join the first sub rail member (230L) with the first seat rail member (226L) and the second sub rail member (230R) with the second seat rail member (226R), in the rear portion (122) of the vehicle (100). Alternatively, a suitable temporary joining technique (e.g., fastening) can be used to join the first sub rail member (230L) with the first seat rail member (226L) and the second sub rail member (230R) with the second seat rail member (226R), in the rear portion (122) of the vehicle (100).

[0049] The first seat rail member (226L) is connected to the first sub rail member (230L) through a first set of trellis members (232L). In the illustrated configuration, the first set of trellis members (232L) forms a triangular configuration with respect to the first seat rail member (226L) and the first sub rail member (230L). This configuration allows a left side of the body frame (102) to be strong, stiff, and lightweight.

[0050] Likewise, the second seat rail member (226R) is connected to the second sub rail member (230R) through a second set of trellis members (232R). In the illustrated configuration, the second set of trellis members (232R) forms a triangular configuration with respect to the second seat rail member (226R) and the second sub rail member (230R). This configuration allows a right side of the body frame (102) to be strong, stiff, and lightweight.

[0051] The body frame (102) further includes a suspension support member (234). The suspension support member (234) is connected to the end portion (212) of the main frame (204) and is adapted to mount the rear suspension member (128). As the main frame (204) is formed as a substantially straight member, the load is transferred from the rear suspension member (128) to the head tube (202) via the main frame (204) that is the shortest path between them.

[0052] Figure 2E illustrates a rear perspective view of portion ‘A’ of Figure 2D, in accordance with an embodiment of the present invention. As shown, the suspension support member (234) is connected to the end portion (212) of the main frame (204) and the first cross frame (206). Herein, the suspension support member (234) extends rearwardly from the main frame (204) and is adapted to mount the rear suspension member (128). The suspension support member (234) includes a first wall (236L), a second wall (236R), and a top wall (236T). The first wall (236L) and the second wall (236R) are disposed in a spaced apart manner, and the top wall (236T) joins the first wall (236L) with the second wall (236R).

[0053] In the specific embodiment, the mounting arrangement of the first wall (236L), the second wall (236R), and the top wall (236T) collectively forman inverted 'U’ shaped structure of the suspension support member (234). Alternatively, based on the feasibility and design requirements of the rear suspension member (128), other structural shapes of the suspension support member (234) are also possible.

[0054] The suspension support member (234) is also provided with a first flange (238L) and a second flange (238R). The first flange (238L) extends outwardly from the first wall (236L) and is adapted to be mounted on the first cross frame (206). Likewise, the second flange (238R) extends outwardly from the second wall (236R) and is adapted to be mounted on the second cross frame (222).

[0055] Further, in a representative example, the suspension support member (234) including the first wall (236L), the second wall (236R), the top wall (236T), the first flange (238L), and the second flange (238R) is formed as a unitary structure. However, in another representative example, the first wall (236L), the second wall (236R), the top wall (236T), the first flange (238L), and the second flange (238R) can be first formed individually and then joined using a suitable joining technique (e.g., adhesive bonding, welding, etc.) to form a unitary structure of the suspension support member (234).

[0056] Furthermore, the suspension support member (234) can be temporarily or permanently connected to the main frame (204) and the first cross frame (206). In the illustrated embodiment, the suspension support member (234) is permanently connected to the main frame (204) and the first cross frame (206) through a suitable permanent joining technique (e.g., welding, adhesive bonding, etc.). However, in another embodiment, the suspension support member (234) can be temporarily connected to the main frame (204) and the first cross frame (206) through suitable fasteners e.g., nuts and bolts, screws, etc.), without limiting the scope of the invention.
