When they need to carry spare objects of different sizes, they cannot effectively perform adaptive extension processing, resulting in their overall low practicality and certain usage limitations. Summary of the Invention

[0007] The present invention aims to provide an extendable tail rack for a motorcycle to solve the problem that most of the above-mentioned background technologies are fixed mounting structures, which cannot effectively perform adaptive extension processing when carrying spare objects of different sizes, resulting in low overall practicality and certain usage limitations.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an extended tail rack for a motorcycle, comprising a reserved base frame, which is installed at the rear end of the motorcycle; an extended movable frame is nested on the outer side of the reserved base frame, and a supporting bearing member is fixedly connected to the inner side of the extended movable frame, and the supporting bearing member is connected to the inner end of the reserved base frame through and docked, a reserved through hole is provided on the surface of the supporting bearing member, and an interfering docking member is nested on the inner side of the reserved base frame, and an auxiliary self-positioning mechanism is provided between the reserved base frame and the extended movable frame, and the extended movable frame is adaptively locked by the auxiliary self-positioning mechanism after the activity.

[0009] Furthermore, the auxiliary self-positioning mechanism is provided with a first liquid capsule, and the first liquid capsule is docked at the lower end of the abutting docking piece, and the first liquid capsule is adhesively connected to the inner side of the extended movable frame, the outer side of the first liquid capsule is penetrated and docked with a supply hose, and the supply hose passes through the inside of the reserved base frame, the inner side of the extended movable frame is penetrated and docked with a second liquid capsule, and the second liquid capsule and the end of the supply hose are connected to each other.

[0010] Furthermore, the outer side of the second liquid sac is fixedly connected to a limiting movable part, and the inner side of the limiting movable part is docked with the outer side of the second liquid sac, the inner side of the limiting movable part is fixedly connected to a return spring, and the return spring is docked with the inner side of the extended movable frame, and a reserved limiting hole is opened on the outer side of the reserved base frame, and the reserved limiting hole corresponds to the position of the limiting movable part.

[0011] Furthermore, the extended movable frame cooperates with the supporting bearing member to form a sliding structure along the outer side of the reserved base frame, and the contact docking member forms a telescopic structure along the outer side of the extended movable frame, and the contact docking member moves inward to synchronously apply pressure to the first liquid capsule in contact, and the first liquid capsule supplies the inside of the second liquid capsule through the supply hose, and the expansion of the second liquid capsule pushes the outer limiting movable member to move horizontally.

[0012] Furthermore, the limiting movable part performs positioning along the reserved limiting holes at the corresponding positions, and the reserved limiting holes are distributed at equal intervals about the outer side of the reserved base frame, and the limiting movable part cooperates with the reset spring to form a reset support.

[0013] Furthermore, a secondary locking structure is provided between the reserved base and the supporting bearing member, and the secondary locking structure is used to limit the bearing strength of the supporting bearing member; the secondary locking structure is provided with a movable resistance member, and the movable resistance member is nested and docked on the inner side of the reserved base, and the outer side of the movable resistance member corresponds to the outer side position of the limiting movable member, and the outer side of the movable resistance member is adhesively connected to a built-in liquid capsule, and the built-in liquid capsule is arranged on the inner side of the reserved base.

[0014] Furthermore, a transverse limiter is nested and installed on the inner side of the reserved base, and a reserved liquid capsule is bonded to the inner side of the transverse limiter, and the reserved liquid capsule is arranged on the inner side of the reserved base, and a supply pipe passes through the outer side of the reserved liquid capsule, and the supply pipe passes through the inner side of the reserved base, and the end of the supply pipe is connected to the built-in liquid capsule.

[0015] Furthermore, the limiting movable part simultaneously applies pressure to the contacting movable resistance part during its movement along the inner end of the reserved limiting hole, and the movable resistance part simultaneously applies pressure to the inner built-in liquid bag, and the built-in liquid bag synchronously supplies liquid to the inside of the reserved liquid bag through the supply pipe.

[0016] Furthermore, the reserved liquid capsule pushes the outer transverse limiting member to move transversely during the process of being pressurized and expanded, and the extended movable frame passes through the transverse limiting member and is connected to the inner side of the supporting bearing member.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The extendable tail rack for motorcycles is provided with an auxiliary self-positioning mechanism, which adaptively locks the extended movable frame after movement through the auxiliary self-positioning mechanism, and the overall tail rack can arbitrarily adjust the position of the extended movable frame according to needs, without any manual adjustment positioning operation and disassembly steps. It is only necessary to move the extended movable frame in conjunction with the supporting bearing member to move laterally along the outer side of the reserved base frame to support the objects or passengers to be carried. In the process of bearing weight, the abutting member on the surface of the extended movable frame will move downward accordingly, and then the abutting member moves inward to synchronously pressurize the first liquid bag in contact with it, so that it is supplied to the inside of the second liquid bag through the supply hose. The expansion of the second liquid bag pushes the outer limiting movable member to move laterally, thereby performing positioning along the reserved limiting hole at the corresponding position on the surface of the reserved base frame, and thus the reserved base frame and the extended movable frame after position adjustment can be positioned and locked, and their extended positions can be effectively fixed.

[0019] Furthermore, when the extended position of the extension movable frame needs to be adjusted or reset, the object to be carried is removed along its surface, and the restoring force of the second liquid bag and the reset spring can drive the limiting movable member to disengage from the transverse locking state between the reserved base frame, thereby making the reserved base frame and the extension movable frame adjustable. This avoids the drawback of the traditional mostly fixed installation structure, which requires replacement of bolts, etc. when disassembling. When it is necessary to carry spare objects of different sizes, it can effectively perform adaptive extension processing, thereby improving the practicality of the overall device.

[0020] Furthermore, a secondary locking structure is provided, which limits the bearing strength of the supporting bearing member. During the movement of the limiting movable member along the inner end of the reserved limiting hole, it will simultaneously apply pressure to the movable resistance member in contact with the inner side of the reserved base frame, so that the movable resistance member applies pressure to the built-in liquid bag on the inside, thereby allowing the built-in liquid bag to cooperate with the supply pipeline to supply the inside of the reserved liquid bag, and the expanded reserved liquid bag pushes the outer lateral limiting member to move horizontally, so that the extended movable frame passes through the lateral limiting member and docks along the reserved through hole corresponding to the surface of the supporting bearing member, thereby performing a secondary self-locking process to ensure its docking strength and stability.
