Description

Technical Field

[0001] The utility model relates to a motorcycle, in particular to a motorcycle with an expansion function. Background Art

[0002] Motorcycles typically have a storage compartment beneath the seat, large enough for helmets, raincoats, and other items. However, motorcycles are increasingly becoming multi-purpose, allowing them to meet a variety of different needs. For example, food delivery drivers may modify their rear racks to hold delivery boxes; some parents may modify their rear racks to hold child seats; and those who travel light on their motorcycles may need a large, flat rear rack for luggage. These needs may only be temporary or require frequent changes in use and adjustments. However, existing motorcycle designs struggle to meet these demands. Utility Model Content

[0055] Reference Figure 4 In one embodiment, the motorcycle M further includes a seat cushion 94 , wherein the first extension tube 31 and the second extension tube 32 extend along two sides of the seat cushion 94 in a top view projection plane.

[0056] Reference Figure 4 In one embodiment, the first extension tube 31 and the second extension tube 32 extend from the front section of the motorcycle M to the rear section of the motorcycle M respectively.

[0057] Matching reference Figure 3 、 Figure 4 In one embodiment, the motorcycle M further includes a second locking unit 2 , wherein the second locking unit 2 is disposed on the second extension tube 32 , and the expansion assembly E1 includes a second fastener 42 , and the second locking unit 2 is locked and connected to the second fastener 42 .

[0058] Figure 6A 、 Figure 6B 、 Figure 6C as well as Figure 6D This is the detailed structure of the first locking unit of an embodiment of the present invention. Figure 7 This is the case where the first locking unit of the embodiment of the present invention is fixed to the frame. Figure 6A 、 Figure 6B 、 Figure 6C as well as Figure 7In one embodiment, the first locking unit 1 includes a hook 11, a fixing base 12, and a latch spring 13. The fixing base 12 is fixedly connected to the first extension tube 31. In one embodiment, the fixing base 12 can be fixed to the first extension tube 31 by screws. The hook 11 is rotatably connected to the fixing base 12. The latch spring 13 connects the hook 11 and the fixing base 12. The latch spring 13 is adapted to apply an elastic force to the hook 11. When the first locking unit 1 is locked with the first latch 41, the hook 11 engages the first latch 41.

[0059] Matching reference Figure 6A 、 Figure 6B as well as Figure 6C In one embodiment, the first locking unit 1 further includes a guiding component 14, which is connected to the fixing base 12. The guiding component 14 is formed with a guiding groove 141. When the first locking unit 1 is locked and connected to the first fastener 41, the first fastener 41 is inserted into the guiding groove 141, and the hook 11 engages with the first fastener 41 to prevent the first fastener 41 from falling out of the guiding groove 141.

[0060] Matching reference Figure 6A 、 Figure 6B 、 Figure 6C as well as Figure 6D In one embodiment, the first locking unit 1 further includes a pivot 15, through which the hook 11 is pivotally connected to the fixing base 12. The latch spring 13 is at least partially mounted on the pivot 15. In a side projection, the pivot 15 is above a line L extending in the depth direction of the guide slot 141. Thus, the first latch 41 is restrained by the hook 11 and is difficult to easily escape from the guide slot 141.

[0061] Matching reference Figure 6A 、 Figure 6B 、 Figure 6C as well as Figure 6D In one embodiment, the hook 11 includes a hook portion 111, which is suitable for abutting the first fastener 41. During the process of inserting the first fastener 41 into the guide groove 141, the hook portion 111 is suitable for rotating toward the front direction X of the motorcycle M to allow the first fastener 41 to reach under the hook portion 111.

[0062] Matching reference Figure 6A 、 Figure 6B 、 Figure 6C as well as Figure 6DIn one embodiment, the fixing seat 12 further includes an abutment wall 121. In a vertical direction V, the abutment wall 121 is located below the pivot 15. The abutment wall 121 is suitable for abutting the hook 11 to prevent the hook portion 111 from excessively rotating toward the rear direction (-X) of the motorcycle M.

[0063] Reference Figure 6A In one embodiment, the fixing seat 12 further includes a limiting portion 122. In one embodiment, the limiting portion 122 is provided on both sides of the hook 11 to limit the hook 11 and prevent the hook 11 from swinging left or right.
