Under the condition that the extending section is not completely arranged in the left-right direction, the design of the frame is not limited, the transverse width and the front-back length are shortened, and therefore appearance adjustment of shortening the width of the pedal, shortening the wheel distance between the front wheel and the rear wheel or reducing the length of the vehicle body is achieved.

Description

Technical Field

[0001] The utility model relates to a transportation vehicle, in particular to a vehicle. Background Art

[0002] See Figure 1 , is a conventional motorcycle frame device 1, comprising a head tube 11, a longitudinal tube 12 connected to the head tube 11 and extending downward, two upper side tubes 13 extending from the longitudinal tube 12 to opposite sides and then bending to extend rearward, a front cross tube 14 connected to the bottom end of the longitudinal tube 12 and extending laterally, two lower side tubes 15 extending rearward from the front cross tube 14 and positioned below the upper side tubes 13 at laterally spaced intervals, and a rear cross tube 16 connected to the upper side tubes 13 and positioned relatively rearward of the front cross tube 14. Each upper side tube 13 includes a bent portion 131 connected to the longitudinal tube 12 and extending in a straight line in the front-to-back direction, and a straight section 132 integrally connected to the bent portion 131. The straight sections 132 of the upper side tubes 13 are parallel to each other, and the distance between the straight sections 132 is approximately equal to the overall width of the motorcycle.

[0003] When the conventional motorcycle frame device 1 is used as an electric vehicle, the placement of an electric motor 71 providing power inevitably requires space for a controller 72 connected to and controlling the electric motor 71. Considering the space required to maintain the fixed dimensions of the controller 72 and the principle of keeping it as close to the electric motor 71 as possible to avoid excessive wiring lengths, the controller 72 is typically mounted between the upper tubes 13 of the frame device 1, with its length extending in the horizontal direction. Due to the fixed dimensions of the controller 72, the upper tubes 13 must also be spaced sufficiently apart.

[0004] However, in recent years, in response to market trends and aesthetic styling, smaller vehicle models have been adopted. For ergonomic reasons and to improve legroom, there's also a trend toward narrower vehicle widths. Without the ability to shorten the spacing between the upper tubes 13, the adjustable configuration of the frame assembly 1 is limited, making it difficult to accurately meet vehicle model adjustments. Therefore, striking a balance between the configuration of the controller 72 and vehicle model adjustments, ensuring optimal compliance with all aspects of vehicle design, has become a key area of ​​focus for researchers in this field. Utility Model Content

[0005] [Problems to be solved by the present utility model]

[0006] Therefore, an object of the present invention is to provide a vehicle that can properly utilize space to configure necessary controllers while shortening the vehicle width.

[0007] [Technical means to solve the problem]

[0008] Therefore, the vehicle of the present invention comprises a vehicle frame, a power motor mounted on the vehicle frame, and a controller mounted on the vehicle frame and located relatively forward of the power motor. A central section passing through the vehicle frame in the front-to-back direction and a transverse section perpendicular to the central section and passing through the controller are defined. The controller has a longest extension extending along the transverse section, the extension being inclined relative to the central section.

[0009] In some embodiments of the present invention, the frame includes a main pipe located on the central section, and two pedal pipes extending rearward from the main pipe, and the distance between the pedal pipes is gradually shortened from rear to front.

[0010] In some embodiments of the present invention, the vehicle further comprises at least one wiring harness connected between the power motor and the controller, wherein the at least one wiring harness is located on the same side of the central section.

[0011] In some embodiments of the present invention, the controller includes a main body and a plurality of fins formed on the main body and extending along an extension direction of the extension section, and the front and rear ends of at least a portion of the fins are respectively located on two opposite sides of the central section.

[0012] In some embodiments of the present invention, the power motor includes a body and a plurality of heat sinks formed on the body and extending in a direction parallel to the central section, and the rear ends of the fins of the controller are toward the front ends of the heat sinks.

[0013] [Effects that can be achieved by this utility model]

[0014] The utility model has the effect of changing the conventional configuration in which the extension section of the controller is arranged vertically across the central section, and utilizing the space of the frame to allow the longer extension section of the controller to extend obliquely forward and backward relative to the central section. As a result, the design of the frame is no longer restricted by the installation method of the controller, and design adjustments can be made to the frame to shorten the lateral width and the length in the front-to-back direction. This can specifically result in an external appearance adjustment such as shortening the lateral width of the pedals, shortening the wheelbase of the front and rear wheels, or reducing the length of the vehicle body in the front-to-back direction.

[0015] In some embodiments of the present invention, the distance between the pedal tubes of the frame directly reflects the leg room of the rider of the vehicle of the present invention. By designing that the distance between the pedal tubes gradually shortens from the rear to the front, the leg room of the rider can be increased, and the position corresponding to the rider's leg landing is relatively narrowed, making it easier for the rider to land his legs when he needs to stop or wait.

[0016] In some embodiments of the present invention, the at least one wiring bundle is connected on the same side relative to the central section, thereby shortening the length of the at least one wiring. This not only reduces wire costs and simplifies connection, but also reduces the voltage drop that decreases with the length of the wiring, making the relevant control transmitted from the controller to the power motor more accurate.

[0017] In some embodiments of the present invention, the fins can guide the airflow introduced from the front, and cross the central section to merge with the airflow introduced from the other side relative to the central section, and then guide it to the power motor, thereby optimizing the overall heat dissipation performance of the controller and the power motor.

[0043] See Figure 2 and Figure 3 , is an embodiment of the vehicle of the present invention, which includes a frame 2, a power motor 3 mounted on the frame 2, a controller 4 mounted on the frame 2 and located relatively forward of the power motor 3, and a wiring harness 5 connected between the power motor 3 and the controller 4. It should be noted that this embodiment specifically also includes a housing 9 that covers the frame 2 and forms the exterior appearance of the vehicle of the present invention. Figure 4 As shown, the housing 9 is formed with a plurality of air intakes 90 opened toward the front and suitable for introducing airflow, and the form of the air intakes 90 is based on the position relative to a front wheel 81, forming two air intake areas on the left and right sides respectively, thereby avoiding the air intake being affected by the obstruction of the front wheel 81 during driving.

[0044] See Figure 5 and Figure 6 and cooperate with Figure 3, defining a central section S passing through the frame 2 in the front-to-back direction, and a transverse section H perpendicular to the central section S and passing through the controller 4. The frame 2 is constructed from a plurality of interconnected alloy pipes and includes a main pipe 21 located on the central section S, and two pedal pipes 22 extending rearward from the main pipe 21. The distance between the pedal pipes 22 gradually decreases from rear to front, which improves the structural strength of the frame 2 compared to a design in which the pedal pipes 22 are parallel and maintained at the same distance. Furthermore, since the outer shell 9 is generally fixed to the periphery of the frame 2, the distance between the pedal pipes 22 can be considered the width of the vehicle after enclosing the outer shell 9 to form the overall appearance of this embodiment. Therefore, when the distance between the pedal tubes 22 is narrowed at specific positions, a wider leg movement space can be provided near the rear according to the position of the rider's legs when riding this embodiment, and the distance is relatively narrowed at the front. In addition to producing a miniaturized appearance, it is also more convenient for the rider to place his feet when stopping.

[0045] See also Figures 4 to 6 The power motor 3 includes a body 31 and a plurality of heat sinks 32 formed on the body 31 and extending in a direction parallel to the central section S. The controller 4 has a Figure 3 ), and the controller 4 includes a main body 41 and a plurality of fins 42 formed on the main body 41 and extending along an extension direction of the extension 49. In this embodiment, since the heat sinks 32 are generally parallel to each other and the fins 42 are also parallel to each other, channels for airflow are formed between adjacent heat sinks 32 and adjacent fins 42.

[0046] like Figure 5 As shown, the extension section 49 of the controller 4 is inclined relative to the central section S. In other words, the controller 4 is arranged in a direction in which the fins 42 are also inclined relative to the central section S. This allows the extension section 49 of the controller 4 to occupy a larger space and extend at an angle. Therefore, the controller 4 can be properly arranged in the limited installation space of the frame 2 by effectively utilizing the space. Figure 7 and cooperate with Figure 4The tilted configuration design of the controller 4 further causes the front and rear ends of a portion of the fins 42 to be located on opposite sides of the central section S. Therefore, the airflow introduced from the air inlet 90 on the left side relative to the front wheel 81 will flow along the channel formed by the fins 42 and then be guided to the right side relative to the central section S, thereby merging with the airflow introduced from the air inlet 90 on the right side relative to the front wheel 81. Furthermore, because the rear ends of the fins 42 are toward the front ends of the heat sinks 32, the airflow that has merged internally will flow toward the power motor 3 and, after achieving the heat dissipation effect, will be guided rearward through the channel formed by the heat sinks 32, thereby forming a path that guides the airflow to flow smoothly, thereby achieving a good heat dissipation effect.

[0047] Re-read Figure 5 The wiring harness 5 is located on the same side of the central section S. Therefore, when connected to the connection point between the power motor 3 and the controller 4, it will not cross the central section S, thereby minimizing the length of the wiring harness 5. This not only reduces wire material costs and simplifies connection, but also reduces the voltage drop that decreases with the length of the wiring, making the relevant control information transmitted from the controller 4 to the power motor 3 more accurate.

[0048] In summary, this embodiment of the vehicle of the present invention utilizes the limited space of the vehicle frame 2 by relatively tilting the extension section 49, which occupies a larger space of the controller 4, to effectively meet the trend of miniaturization. Furthermore, the relatively tilted configuration of the controller 4 also guides airflow, thereby achieving a good heat dissipation effect for the controller 4 and the power motor 3. Therefore, the purpose of the present invention is effectively achieved.

[0049] The above description is merely an embodiment of the present invention and cannot be used to limit the scope of implementation of the present invention. Any simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention patent.
