Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle technology, and in particular to a folding electric bicycle frame. Background Technology
[0002] A folding electric bicycle is an electric bicycle designed with a foldable structure. The folding mechanism significantly reduces the overall size of the vehicle, making it easy to carry, store, and transport. These electric bicycles typically combine the lightweight nature of traditional bicycles with the convenience of electric bicycles, providing users with an efficient, environmentally friendly, and flexible mode of transportation.
[0003] Currently, traditional folding electric bicycles on the market often rely on numerous screws for fixing and folding. Users need to loosen the screws, then fold the handlebars downwards or inwards, and finally tighten the screws again. This fixing method requires turning a large number of screws, making the operation cumbersome and inconvenient for users to rotate and fold the electric bicycle handlebars. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a folding electric bicycle frame.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A folding electric bicycle frame includes a fixed column and a rotating column. A handlebar assembly is fixedly mounted on the top of the rotating column, and a rotating seat is fixedly mounted on the bottom of the rotating column. A fixed seat is mounted on the top of the fixed column, and the rotating seat rotates on the fixed seat via a rotating hinge. A movable component is movably mounted above the rotating seat, and multiple limiting columns are fixedly and vertically mounted downwards on the bottom of the movable component. A fixing component is fixedly mounted on the bottom of the fixed seat, and each of the fixing components has a silicone pleated cavity adapted to fit the limiting columns.
[0007] In addition, a preferred structure is that both the fixed seat and the rotating seat are provided with multiple through holes, and the through holes are adapted to the limiting post.
[0008] In addition, a preferred structure is that the top of the rotating seat has a cavity facing downwards, a threaded post is rotatably arranged in the cavity, and a knob is fixedly arranged on the top of the threaded post.
[0009] Furthermore, in a preferred configuration, the movable part has a threaded cavity adapted to the threaded post, and the movable part is driven to move by the threaded post.
[0010] Furthermore, a preferred configuration is that the fixed base and the rotating base are adapted to each other, and the rotating base is mounted on the fixed base via a rotary hinge.
[0011] Furthermore, a preferred configuration is that when the rotating seat is located on top of the fixed seat, the limiting post, the through hole, and the silicone pleated cavity are adapted and aligned.
[0012] The beneficial effects of this utility model are as follows: the handle assembly can be folded by rotating the hinge, and the fixed seat and the rotating seat can be fixed by the interlocking between the limiting post, the through hole, and the silicone pleated cavity. This fixing method is simple to operate and makes it easy for users to fold the handle assembly. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figure 1-4 A folding electric bicycle frame includes a fixed column 1 and a rotating column 2. A handlebar assembly 22 is fixedly mounted on the top of the rotating column 2, and a rotating seat 21 is fixedly mounted on the bottom of the rotating column 2. A fixed seat 11 is mounted on the top of the fixed column 1, and the rotating seat 21 rotates on the fixed seat 11 via a rotating hinge 6. A movable component 3 is movably mounted above the rotating seat 21, and multiple limiting columns 31 are vertically fixedly mounted downwards on the bottom of the movable component 3. A fixing component 4 is fixedly mounted on the bottom of the fixed seat 11, and each of the fixing components 4 has a silicone pleated cavity 41 corresponding to one of the limiting columns 31.
[0020] Both the fixed base 11 and the rotating base 21 are provided with multiple through holes 7, and the through holes 7 are adapted to the limiting post 31.
[0021] The rotating base 21 has a downward-facing cavity at its top, within which a threaded post 5 is rotatably mounted, and a knob 51 is fixedly mounted on the top of the threaded post 5. The movable part 3 has a threaded cavity 32 corresponding to the threaded post 5, and the movable part 3 is driven to move via the threaded post 5. The threaded post 5 is rotatably mounted within the cavity via a bearing, and a knob 51 is fixedly mounted on the top of the threaded post 5. Rotating the knob 51 rotates the threaded post 5, which in turn drives the movable part 3 to move vertically. It is worth noting that a damping mechanism, as used in the prior art, is provided between the threaded cavity 32 and the threaded post 5 to prevent the threaded post 5 from becoming excessively loose. This is prior art and will not be elaborated further.
[0022] The fixed base 11 and the rotating base 21 are adapted to each other, and the rotating base 21 is mounted on the fixed base 11 via a rotary hinge 6. The rotary hinge 6 allows the rotating base 21 to rotate around it. It is worth noting that the specific rotation structure and installation method of the rotary hinge 6 are existing technologies and will not be described in detail here.
[0023] When the rotating seat 21 is located on top of the fixed seat 11, the limiting post 31, the through hole 7 and the silicone pleated cavity 41 are adapted and aligned.
[0024] In this embodiment, the fixing post 1 is located at the front end of the electric bicycle, and a length adjustment mechanism is provided at the bottom of the fixing post 1 to adjust the height of the handlebar assembly 22. It is worth noting that this is prior art, and therefore will not be described in detail.
[0025] Furthermore, when the user needs to fold and rotate the handle assembly 22, they only need to rotate the threaded post 5 using the knob 51, causing the movable part 3 to move upwards through the rotation of the threaded post 5. This allows the limiting post 31 and the movable part 3 to move upwards synchronously. Once the limiting post 31 has disengaged from the through hole 7, the user can rotate the rotating seat 21 and the rotating post 2 by rotating the hinge 6, thereby rotating the handle assembly 22 and thus folding the handle assembly 22.
[0026] Furthermore, when the user needs to reassemble the handle assembly 22, they simply rotate the handle assembly 22 again via the rotating hinge 6, causing the rotating seat 21 to rotate back above the fixed seat 11. Then, the user simply rotates the threaded post 5 in the opposite direction via the knob 51, causing the moving part 3 to move downwards, which in turn causes the limiting post 31 to move downwards simultaneously. This allows the limiting post 31 to pass sequentially through the through hole 7 of the rotating seat 21 and the through hole 7 of the fixed seat 11, and then be inserted into the silicone pleated cavity 41. This secures the fixed seat 11 and the rotating seat 21, thus achieving the fixed assembly of the handle assembly 22.
[0027] It is worth noting that the inner wall of the silicone pleated cavity 41 is covered with pleated silicone, and the silicone pleated cavity 41 is through-hole. This can increase the friction between the limiting post 31 and the silicone pleated cavity 41, making it less likely to fall out of the silicone pleated cavity 41 easily.
[0028] In this invention, the handle assembly 22 can be folded by rotating the hinge 6, and the fixed base 11 and the rotating base 21 can be fixed by the mutual locking between the limiting post 31, the through hole 7, and the silicone pleated cavity 41. This fixing method is simple to operate and makes it easy for users to fold the handle assembly 22.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
