Description

Technical Field

[0001] This invention relates to an electric-assisted bicycle, and more particularly to an electric-assisted bicycle that is easy to adjust. Background Technology

[0002] A power-assisted bicycle is a new type of two-wheeled vehicle. Its basic frame is derived from a bicycle, but it uses a battery as an auxiliary power source, is equipped with a motor, and has a power assistance system, making it a new type of transportation that integrates human riding and motor assistance.

[0003] Existing electric-assisted bicycles are designed for convenient travel. However, during the transfer of electric-assisted bicycles, workers arrange the bicycles neatly and then tie them together with only a single rope. Because electric-assisted bicycles have many moving parts, such as handlebars and wheels, conventional binding methods are insufficient to achieve the desired fixation, which can easily lead to the bicycle tipping over after being moved. Therefore, it is necessary to design an electric-assisted bicycle that can fix the moving parts through an adjustable structure. Summary of the Invention

[0004] To overcome the drawback of existing electric-assisted bicycles where moving parts are difficult to secure, leading to transportation difficulties, the technical problem to be solved is to provide an electric-assisted bicycle that is easy to adjust and can secure moving parts for easy transportation.

[0005] An easily adjustable electric-assisted bicycle includes a frame frame, wheels, handlebar brackets, seat brackets, and pedal brackets. The wheels are rotatably mounted at the front and rear ends of the frame frame. The handlebar brackets are rotatably connected to the front end of the frame frame via hinges. The seat brackets are rotatably connected to the middle of the frame frame via hinges. The bicycle also includes a limiting mechanism and a rotating mechanism.

[0006] Furthermore, it is particularly preferred that the limiting mechanism includes a first fixed rod, a limiting frame, and a first return spring. The first fixed rod is disposed at the front end of the vehicle body bracket, and the limiting frame is slidably connected inside the first fixed rod, with the first return spring connecting the two.

[0007] Furthermore, it is particularly preferred that the rotating mechanism includes a second fixed rod, an L-shaped locking rod, and a second return spring. The second fixed rod is fixed to the front end of the body bracket and is located at the connection between the body bracket and the handle bracket. The L-shaped locking rod is limited to slide on the second fixed rod and the two are connected by a second return spring. The L-shaped locking rod can engage with the handle bracket.

[0008] Furthermore, it is particularly preferred that the device also includes a locking mechanism, which includes a third fixing rod, a locking block, and a third return spring. The third fixing rod is laterally fixed to the front side of the foot pedal bracket, and the locking block is slidably connected to the third fixing rod with a limit, and the third return spring is connected between the two.

[0009] Furthermore, it is particularly preferred that the device also includes a push rod and a first wedge block, with the push rod keyed to the pivot of the handlebar bracket, the pivot being the connecting pivot between the handlebar bracket and the vehicle body bracket, the first wedge block being fixed to the upper part of the limiting frame, and the push rod being able to make frictional contact with the first wedge block.

[0010] Furthermore, it is particularly preferred that the device also includes a folding mechanism, which includes a fourth fixing rod, a locking rod, and a fourth return spring. The fourth fixing rod is located in the middle of the vehicle body bracket, and the locking rod slides on the fourth fixing rod with a limit, and the two are connected by the fourth return spring.

[0011] Furthermore, it is particularly preferred that the device also includes a sliding seat and a second wedge block, the sliding seat being limited to slide on the vehicle body bracket, the second wedge block being fixed to the locking block, and the lower end of the sliding seat being in frictional contact with the second wedge block.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] Rotating the handlebar bracket allows the L-shaped locking lever to limit and fix the handlebar bracket. The handlebar bracket can be pushed downwards by the push rod, and the limiting frame can rub and fix the wheel. After rotating the handlebar bracket to the sliding seat, it can be pushed downwards, and the sliding seat can drive the locking block to limit and fix the foot pedal. This achieves the limitation and fixation of the moving parts of the electric-assisted bicycle, making it easier to transport the bicycle. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0025] Example 1

[0026] An easily adjustable electric-assisted bicycle, such as Figures 1-4 , Figures 6-8 As shown, the device includes a body frame 1, a wheel 101, a handlebar bracket 2, a seat bracket 3, and a footrest bracket 4. The wheel 101 is rotatably mounted at the front and rear ends of the body frame 1. The handlebar bracket 2 is rotatably connected to the front end of the body frame 1 via a hinge. The seat bracket 3 is rotatably connected to the middle of the body frame 1 via a hinge. The footrest bracket 4 is located at the lower part of the body frame 1. A power assembly is installed inside the footrest bracket 4. The power assembly includes a battery power source and a chain. The power assembly is connected to the wheel 101. The device also includes a limiting mechanism 5 and a rotating mechanism 6.

[0027] like Figure 1 and Figure 2 As shown, the limiting mechanism 5 includes a first fixed rod 501, a limiting frame 502, and a first return spring 503. The first fixed rod 501 is disposed at the front end of the vehicle body bracket 1. The limiting frame 502 is slidably connected inside the first fixed rod 501, and the first return spring 503 is connected between the two. The lower end of the limiting frame 502 is U-shaped and made of rubber. When the limiting frame 502 is moved downward to contact the wheel 101, the limiting frame 502 can limit and fix the wheel 101.

[0028] like Figure 1 and Figure 3As shown, the rotating mechanism 6 includes a second fixed rod 601, an L-shaped locking rod 602, and a second return spring 603. The second fixed rod 601 is fixed to the front end of the body bracket 1 and is located at the connection between the body bracket 1 and the handle bracket 2. The L-shaped locking rod 602 is limited to slide on the second fixed rod 601, and the second return spring 603 is connected between the two. The L-shaped locking rod 602 can engage with the handle bracket 2. The handle bracket 2 is rotatably connected to the body bracket 1. In the initial state, the L-shaped locking rod 602 engages and fixes the handle bracket 2. When the L-shaped locking rod 602 is pulled outward until the second return spring 603 retracts, the handle bracket 2 is rotated from vertical to horizontal, and then the L-shaped locking rod 602 is reset. The L-shaped locking rod 602 can fix the handle bracket 2 in the horizontal state.

[0029] Example 2

[0030] Based on Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, it also includes a locking mechanism 7, which includes a third fixing rod 701, a locking block 702 and a third return spring 703. The third fixing rod 701 is horizontally fixed to the front side of the foot pedal bracket 4. The locking block 702 is slidably connected to the third fixing rod 701 and the third return spring 703 is connected between the two. The side of the locking block 702 is provided with a groove, and the locking block 702 can limit and fix the foot pedal through the groove.

[0031] like Figure 6 As shown, it also includes a push rod 801 and a first wedge block 802. The push rod 801 is keyed to the rotating shaft of the handlebar bracket 2. The rotating shaft is the connecting shaft between the handlebar bracket 2 and the body bracket 1. The first wedge block 802 is fixed to the upper part of the limiting frame 502. The push rod 801 can make frictional contact with the first wedge block 802. When the handlebar bracket 2 rotates, the push rod 801 rotates synchronously with the handlebar bracket 2. The push rod 801 can contact and push the first wedge block 802 to slide downward, thereby pushing the limiting frame 502 to contact the wheel 101, so as to realize the limitation and fixation of the wheel 101.

[0032] like Figure 1 and Figure 7 As shown, it also includes a folding mechanism 9, which includes a fourth fixing rod 901, a locking rod 902 and a fourth return spring 903. The fourth fixing rod 901 is located in the middle of the body bracket 1, and the locking rod 902 slides on the fourth fixing rod 901 and the fourth return spring 903 connects the two. The seat bracket 3 can rotate on the body bracket 1, and the locking rod 902 is used to lock and fix the seat bracket 3.

[0033] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a sliding seat 1001 and a second wedge block 1002. The sliding seat 1001 is limited to slide on the vehicle body bracket 1, and the second wedge block 1002 is fixed to the locking block 702. The lower end of the sliding seat 1001 is in frictional contact with the second wedge block 1002. The upper end of the sliding seat 1001 is a receiving part, which is used to receive and fix the handle bracket 2. The lower end of the sliding seat 1001 is provided with an inclined surface. When the handle bracket 2 rotates to the sliding seat 1001, the handle bracket 2 pushes the sliding seat 1001 downward, and the sliding seat 1001 pushes the second wedge block 1002 to move horizontally, so that the locking block 702 can be locked onto the foot pedal, thereby fixing the foot pedal.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
