Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a three-section folding electric bicycle. Background Technology

[0002] The three-section folding electric bicycle is a portable transportation tool with a highly flexible segmented folding design (steering handlebar stem section, steering wheel section, and pedal section) as its core selling point. Its biggest feature is that it can be quickly disassembled and stored through the hinge or pin structure in the middle of the frame, stem, and handlebars. After folding, its volume is greatly reduced, making it easy to store in the trunk of a car, subway car, or office corner.

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] While existing three-section folding electric bicycles can be folded during use, the folding point is usually the handlebars and steering wheels folded together, making them inconvenient to move after folding.

[0005] In addition, after folding, there is a gap between the steering stem and the pedals, which can cause the handlebars and pedals to bump against each other during movement, thus reducing the lifespan of the handlebar controller. Furthermore, although some folding electric bicycles can position the stem and pedals after folding, the stem has a certain length, which can cause it to wobble during movement, putting stress on the stem and reducing its lifespan.

[0006] Therefore, this solution provides a three-section folding electric bicycle to address the aforementioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a three-section folding electric bicycle to solve the problems in the prior art where the folding position makes it inconvenient to move after folding and that folding and moving reduces the service life of the controller and pole.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] A three-section folding electric bicycle includes a throttle mechanism, a steering mechanism, and a pedal mechanism. The steering mechanism is located to one side of the pedal mechanism and below the throttle mechanism. A folding mechanism is provided between the throttle mechanism and the steering mechanism.

[0038] Please refer to the following. Figures 1 to 10 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0039] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0040] This utility model provides a three-section folding electric bicycle, including a throttle mechanism 1, a steering mechanism 2 and a pedal mechanism 3. The steering mechanism 2 is located on one side of the pedal mechanism 3 and at the lower end of the throttle mechanism 1. A folding mechanism 7 is provided between the throttle mechanism 1 and the steering mechanism 2. A buffer mechanism 5 is provided above the pedal mechanism 3. A locking mechanism 4 is provided at the lower end of the throttle mechanism 1.

[0041] The throttle mechanism 1 includes a steering column 11, a front light 12, a controller 13 and a steering handle 14, and a hook 6 is installed on one side of the steering column 11;

[0042] Steering mechanism 2 includes steering beam 21, front steering wheel 22, connecting block 23 and insert shaft 24;

[0043] The pedal mechanism 3 includes a pedal box 31, a footrest 32, a connecting beam 33, a connecting plate 34, a taillight 35, a rear wheel 36, and a rubber shock absorber 37;

[0044] The folding mechanism 7 includes an upper alloy frame 71 and a lower alloy frame 72 that are rotatably connected by a shaft. A knob 73 is provided on one side of the upper alloy frame 71 and the lower alloy frame 72.

[0045] The clamping mechanism 4 includes a clamping ring 41 bolted to the lower end of the steering column 11 and a clamping head 42 fixedly connected to the outside of the clamping ring 41;

[0046] The buffer mechanism 5 includes a mounting base 51, a buffer base 52 and a snap-fit ​​base 53 arranged from top to bottom. The buffer base 52 has two centrally symmetrical buffer components 58 inside.

[0047] Hook 6 is used to hang objects. It is made of high-strength aluminum alloy and is a folding hook assembly manufactured in one piece through stretching. The upper alloy frame 71, lower alloy frame 72 and knob 73 constitute a new three-section folding system. It is made of high-strength aluminum alloy through one-piece forging. After the upper alloy frame 71 and lower alloy frame 72 are installed, they are locked by the screw knob 73, which makes it more secure. The back of the knob 73 has a locking plate that can simultaneously lock one side of the upper alloy frame 71 and the lower alloy frame 72, thereby completing the locking.

[0048] In a further embodiment, the mounting base 51 is bolted between two connecting plates 34, the buffer base 52 is fixedly connected above the mounting base 51, and the inner side of the snap-fit ​​base 53 is slidably connected with two symmetrical snap-fit ​​blocks 54, and a spring 55 is provided on one side of the snap-fit ​​block 54.

[0049] In this embodiment, when the steering column 11 is rotated and folded, it is parallel to the end face of the mounting base 51, so that the snap connector 42 can be inserted into the interior of the snap connector 53. Both the snap connector 42 and the snap connector block 54 have beveled surfaces, so that when the snap connector 42 moves down, the snap connector block 54 can be pushed. The spring 55 resets the position of the snap connector block 54.

[0050] In a further embodiment, a top block 56 is slidably connected up and down inside the snap-fit ​​base 53, and a connecting plate 57 is fixedly connected to the top block 56 outside the snap-fit ​​base 53. The buffer assembly 58 includes a connecting foot 581 that can be slidably connected up and down inside the buffer seat 52 and a pressure plate 584 that can be slidably connected left and right inside the buffer seat 52.

[0051] In this embodiment, the top block 56 has oblique protrusions at both ends, so that when it moves upward, the two locking blocks 54 can move away from each other; the connecting plate 57 is used to facilitate the user to lift the top block 56.

[0052] In a further embodiment, a buffer spring 582 is provided below the connecting foot post 581, a rubber friction block 585 is installed on one side of the pressure plate 584, the rubber friction block 585 is in contact with the inner side of another connecting foot post 581, and a connecting rod 583 is movably connected between the connecting foot post 581 and the pressure plate 584.

[0053] In this embodiment, the two ends of the connecting rod 583 are rotatably connected to the connecting foot 581 and the pressure plate 584 via a shaft; the buffer spring 582 is used for initial buffering when moving downwards, and when the connecting foot 581 moves downwards, the connecting rod 583 causes the pressure plate 584 to move horizontally, so that the rubber friction block 585 can squeeze the inner side of the connecting foot 581 when it moves downwards, thereby increasing the friction force to slow down its downward movement, and thus providing secondary buffering.

[0054] In a further embodiment, the steering handle 14 is installed at the top of the steering column 11, the controller 13 is installed in the middle of the steering handle 14, the headlight 12 is installed on one side of the steering column 11, the upper end of the steering beam 21 is fixedly connected to the insert shaft 24, the periphery of the insert shaft 24 is fixedly connected to the connecting block 23, the lower alloy frame 72 is installed above the connecting block 23 and located on the periphery of the insert shaft 24, and the upper alloy frame 71 is installed at the bottom of the steering column 11.

[0055] In this embodiment, the insert shaft 24 is a front fork tube made of a single solid aluminum rod, which is connected to the steering beam 21 by extrusion and welding processes, resulting in better strength and higher dimensional accuracy than traditional iron pipes.

[0056] In a further embodiment, the front steering wheel 22 is rotatably connected to the inner side of the steering beam 21, one end of the foot support 32 is movably connected to one side of the pedal box 31, and two symmetrical connecting plates 34 are connected to the top of the main beam 33 by bolts, and the other side of the connecting plate 34 is connected to the connecting block 23.

[0057] In this embodiment, the connecting beam 33 is a non-spliced ​​integrated beam, which adopts a high-strength aluminum alloy material and an integrated stretching process. It has better strength and dimensional accuracy than the traditional average beam, which can avoid the cumbersome splicing and installation process and reflect the overall appearance. One end of the foot support 32 has an ear plate, which allows the foot support 32 to rotate and connect. At the connection between the foot support 32 and the pedal box 31, the pedal box 31 has a groove that allows the foot support 32 to be embedded after being retracted. This allows the foot support 32 to be hidden after being retracted, which is more aesthetically pleasing. There is a hollow plate on the top of the pedal box 31, and the battery pack inside the pedal box 31 is used for power supply.

[0058] In a further embodiment, the taillight 35 is embedded in one end of the foot pedal box 31, the rear wheel 36 is rotatably connected to one end of the foot pedal box 31, and the rubber shock absorber 37 is installed at the point where the rear wheel 36 is rotatably connected to the foot pedal box 31.

[0059] In this embodiment, the taillight 35 and the rear foot pedal are designed as a whole, which is not a traditional separate taillight; the rubber shock absorber 37 is a hidden rubber shock absorber.

[0060] The working principle of this utility model is as follows:

[0061] When folding is required, the knob 73 can be rotated so that the plate on one side is no longer engaged between the upper alloy frame 71 and the lower alloy frame 72. This allows the throttle mechanism 1 to rotate around the rotatable connection between the upper alloy frame 71 and the lower alloy frame 72. After rotation, the engagement mechanism 4 on the outer periphery of the bottom of the steering column 11 will engage with the buffer mechanism 5, thereby limiting the distance between the throttle mechanism 1 and the pedal mechanism 3 after folding. At this time, both the front steering wheel 22 and the rear wheel 36 are in contact with the ground, making it easy to move.

[0062] When folding, the locking mechanism 4 rotates with the throttle mechanism 1, and the locking head 42 at the bottom of the clamp ring 41 will be inserted into the interior of the locking seat 53, thereby pressing the two locking blocks 54 to both sides. After the locking head 42 is fully inserted into the locking seat 53, the spring 55 rebounds and resets the position of the locking blocks 54, thus allowing the locking mechanism 4 to connect with the locking seat 53. If it is necessary to disengage, the connecting plate 57 can be lifted so that the top block 56 also moves up and pushes the locking blocks 54 to both sides, thereby releasing the restriction on the locking head 42.

[0063] When the locking mechanism 4 is connected to the locking seat 53 and the entire electric bicycle needs to be moved, it can be moved through the folded steering column 11. The shaking generated during the movement will cause the locking seat 53 to move up and down along with the buffer assembly 58. During this movement, on the one hand, the buffer spring 582 under the connecting foot post 581 can provide initial buffering, and on the other hand, the up and down movement of the connecting foot post 581 will cause the pressure plate 584 to slide back and forth inside the buffer seat 52 through the connecting rod 583. As a result, the pressure plate 584 continuously pushes the rubber friction block 585 closer to the inner side of the connecting foot post 581. Whenever the rubber friction block 585 gets close to the inner side of the connecting foot post 581, the friction will slow down the downward movement speed of the connecting foot post 581, thus providing buffering again. This not only avoids the collision between the controller 13 at one end of the steering column 11 and the pedal box 31, but also absorbs the shaking during movement, thereby extending the service life of the controller 13 and the steering column 11.

[0064] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
