Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a frame structure of a shared electric bicycle. Background Art

[0002] Currently, bicycles, especially shared electric bicycles, have a high probability of being damaged. When maintaining the battery, it is inconvenient to disassemble and install, and parts such as controllers are relatively easy to be damaged, resulting in a high labor cost for maintenance. This is mainly because the battery of traditional electric bicycles adopts an upward-taking installation structure, which causes interference when the battery is taken out from bottom to top or installed from top to bottom in the case of insufficient upper space, such as being blocked by a cross bar, making the operation inconvenient. Also, the controller of traditional electric bicycles is generally installed together with the battery. If the controller fails, it is necessary to first disassemble the socket at the end of the battery to remove the controller for maintenance, which is time-consuming and laborious and has low efficiency. At the same time, the saddle tube is usually equipped with a matching wrench for tightening or loosening to achieve the purpose of installation, disassembly, and adjustment, but this easily leads to the theft of the saddle tube. In addition, some controllers are disassembled backward from the control box at the bottom of the frame, resulting in inconvenient disassembly, assembly, and maintenance.

It is characterized in that: a control box is arranged at the bottom of the frame body, the controller is installed in the control box, and the bottom ends of the front rod and the rear rod are respectively connected to the control box to form the whole frame body.

[0005] Further, the battery adopts a side-pull installation structure, a connection part is arranged at its upper end, and a lock hole is arranged on the connection part; a battery slot is arranged on the front rod, a lock seat matching with the connection part is arranged at the upper end of the battery slot, a lock body is arranged on the lock seat, the lock body has a lock core, the battery is inserted into the battery slot from the side of the front rod so that its lock hole is aligned with the lock core, and the lock core is controlled by the lock body to protrude outward and insert into the lock hole to realize the locking of the battery; the bottom end of the battery is inserted and assembled with a socket, and the socket is fixed on the front rod at the bottom end of the battery slot.

[0006] Further, the control box adopts a structure with an opening on the side, at least one side of it is provided with a box cover, and the box cover is fixed at the side opening of the control box by screws to enclose the controller in the control box.

[0007] Further, the saddle tube is locked and fixed to the rear rod through a ferrule with a wrench. Screw holes are provided on the ferrule, the rear rod, and the saddle tube. The saddle tube is fixed by using anti-theft screws to sequentially pass through the screw holes of the three, thereby achieving the anti-theft effect on the saddle.

[0008] Preferably, the tail end of the anti-theft screw uses an inwardly concave triangular hole as the unlocking structure, and a matching three-key is required to open it.

[0009] Further, the control box, the front rod, and the rear rod are all made of metal materials, and the control box connects the front rod and the rear rod into an integrated frame body.

[0010] Further, a basket is provided at the front end of the frame body. The basket is made of stainless steel material to improve the structural strength.

[0011] Further, a vehicle lamp is provided at the front end of the frame body. The vehicle lamp is located below the basket and is connected to the controller.

[0012] In the present utility model, by arranging a control box at the bottom and connecting it to the bottom ends of the front rod and the rear rod to form a frame body, the control box serves two purposes. It not only makes the frame body have high structural strength but also can save space, and it is more convenient to disassemble and assemble the controller from the side. The saddle tube adopts an anti-theft structure design, which can reduce the situation of being stolen. In addition, the battery adopts a side-pull installation structure, and it can be taken down by pulling it out to the side after unlocking, avoiding the inconvenience of battery removal and installation for models with crossbars.
