Description

This invention relates to the technical field of brackets for electric bicycles, and more specifically to a bracket for an S-shaped rear fork dropout of an electric bicycle.

As society develops, traffic congestion becomes more and more severe, and a series of electric bicycles that are light, small and easy to carry are gaining popularity. Traditional small electric bicycles do not have a shock absorbing design, which makes the ride uncomfortable, or the short shock absorbers are ineffective, making it difficult to enjoy riding an electric bicycle, which causes inconvenience to consumers. The physical structure limitations and technical shortcomings caused by traditional design defects have yet to be resolved.

The main points are as follows:

(1) The limitations of the physical structure refer to the fact that the operating stroke of a short shock absorber is limited to 15-18 mm. As a result, due to the small size of compact cars, shock absorbers with long strokes cannot be installed on them, and the impact absorption effect is poor due to the short stroke.

(2) The shock absorber must be installed with an upward pressure. When the electric bike goes over a speed bump and is pushed down to its limit, the spring's return force becomes an upward repulsive force, making the electric bike shake and unstable, resulting in greater resistance and higher energy consumption.

The purpose of this invention is to provide a bracket for an S-shaped rear fork dropout of an electric bicycle that can provide a solution to the shortcomings of the conventional technology. The lateral shock absorber can be mounted so that one end closer to the front end of the vehicle is low and the other end closer to the rear end of the vehicle is high. This allows the lateral shock absorber to act as a soft tail, and since a forward force is generated during shock absorption, it does not need to be pressed upward when mounted, and the operating stroke of the shock absorber does not need to be very long. In addition, the short shock absorber also has an excellent shock absorbing effect, which increases comfort and makes the electric bicycle more stable and safe.

This invention employs the following technical solutions:

An embodiment of the present application provides a bracket for an S-shaped rear fork dropout of an electric bicycle, which includes two bracket bodies arranged opposite each other, each bracket body including an inclined straight arm support rod and an S-shaped bracket rod, a higher end of the straight arm support rod is connected to the bracket rod, the straight arm support rod and the bracket rod form an "S" shape, and a connection component is fixedly connected between the two straight arm support rods.

Furthermore, in some embodiments of the present invention, the lower end of the straight arm support rod is provided with an axle mounting groove.

Furthermore, in some embodiments of the present invention, one of the straight arm support rods is provided with a brake mounting hole.

Furthermore, in some embodiments of the present invention, the upper end of the bracket rod is provided with a mounting hole for a lateral shock absorber.

Furthermore, in some embodiments of the present invention, a hole for the rotation shaft of the rear fork is provided at the lower end of the bracket rod.

Furthermore, in some embodiments of the present invention, the above-mentioned connection component includes a connecting rod, one end of the connecting rod being fixedly connected to one of the straight arm support rods and the other end of the connecting rod being fixedly connected to the other of the straight arm support rods.

Furthermore, in some embodiments of the present invention, a mounting sleeve is provided between the connecting rod and the straight arm support rod, the mounting sleeve is fixed to the straight arm support rod, and the end of the connecting rod is fitted into the mounting sleeve and fixedly connected to the mounting sleeve.

Compared to conventional techniques, the embodiments of the present invention have at least the following advantages or beneficial effects:

An embodiment of the present invention provides a bracket for an S-shaped rear fork dropout of an electric bicycle, which includes two bracket bodies arranged opposite each other, each bracket body including an inclined straight arm support rod and an S-shaped bracket rod, a higher end of the straight arm support rod is connected to the bracket rod, the straight arm support rod and the bracket rod form an "S" shape, and a connection component is fixedly connected between the two straight arm support rods.

The lateral shock absorber can be installed so that one end closer to the front end of the vehicle is low and the other end closer to the rear end of the vehicle is high, allowing the lateral shock absorber to act as a soft tail, and since a forward force is generated during shock absorption, it does not need to be installed by pressing upwards, and the operating stroke of the lateral shock absorber does not need to be very long, and the short shock absorber also has a good shock absorption effect, is more comfortable, and makes the electric bicycle more stable and safer.

In the description of the embodiments of the present invention, unless otherwise specified or limited, the terms "disposition" and "connection" should be understood in a broad sense, and may refer to, for example, a fixed connection, a removable connection or an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, an internal communication between two elements, etc. Those skilled in the art can understand the specific meaning of the above terms in the present invention on a case-by-case basis.

Referring to Figures 1 to 3, this embodiment provides a bracket for an S-shaped rear fork dropout of an electric bicycle, which includes two bracket bodies arranged opposite each other, each bracket body includes a straight arm support rod 1 arranged at an angle and an S-shaped bracket rod 2, the higher end of the straight arm support rod 1 is connected to the bracket rod 2, the straight arm support rod 1 and the bracket rod 2 form an "S" shape, and a connection component for fixing the two bracket bodies is fixedly connected between the two straight arm support rods 1.

The lower end of the straight arm support rod 1 in this embodiment is provided with an axle mounting groove 3 for mounting the rear wheel axle of an electric bicycle.

In this embodiment, a brake mounting hole 4 for mounting a brake is provided on one side of the straight arm support rod 1. In this embodiment, a rear fork rotating shaft hole 6 for mounting the rotating shaft of the foot pedal is provided on the lower end of the bracket rod 2.

In actual use, the upper end of the bracket rod 2 is provided with a horizontal shock absorber mounting hole 5, through which one end of the damping shock absorber and the upper end of the bracket rod 2 are attached via a pin. When attached, the end of the damping shock absorber attached to the brake mounting hole 4 is high, and the other end of the damping shock absorber is closer to the front end of the car and is lower in height, thus mounting the damping shock absorber so that the end closer to the front end of the car is lower and the end closer to the rear end of the car is higher. The main features of the S-shaped bracket rod 2 are as follows: S is actually a combination of two Cs in reverse, and when the rear fork bracket body is pressed down, one C is pushed forward, which means that the direction of the force is not upward, and in this case, in the conventional technology, the chain of the electric bicycle becomes longer and falls off, but the reverse C is opened, which at the same time compensates for the angle, keeps the axis position always in the center position, and prevents the chain from being pulled or falling off.

The operating principle of the S-shaped rear fork dropout bracket of the present application is to change the direction of force, and since the lateral shock absorbers supporting the vehicle body are not installed by pressing diagonally upwards, when the vehicle passes a speed bump and is pushed down beyond its limit, the repulsive force pushes forward, making the vehicle more stable, safe and energy-saving. In addition, the operating stroke of the lateral shock absorbers does not need to be so long, and the front end of the lateral shock absorbers can be lowered and the rear end raised, so that the soft tail effect of the lateral shock absorbers can be obtained, and they also have an excellent effect as short shock absorbers, improving comfort.

In another example, the disadvantage of mounting the shock absorber by pressing it upwards is that the tire is lowered by 2 cm, and according to the principle ratio, the stroke of the shock absorber is shortened by 2 cm. Short shock absorbers often have insufficient stroke, resulting in poor shock absorption effect.

The lateral shock absorber of the present application is designed with a low front and high rear, so that when the tire is lowered by 2 cm, the stroke of the lateral shock absorber only moves 0.5 cm, so the operating stroke does not need to be so long, making up for the shortcomings of short shock absorbers. The S-shaped rear fork dropout bracket design has a low front end and a high rear end, so the lateral shock absorber has a soft tail and will not flip over even if it is pushed down extremely, and can be applied to four-wheel independent suspension of bicycles, mopeds, motorcycles, scooters, and automobiles.

Referring to Figures 1 to 3, in some embodiments of the present invention, the above-mentioned connection component includes a connecting rod 7, one end of the connecting rod 7 is fixedly connected to one of the straight-arm support rods 1, and the other end of the connecting rod 7 is fixedly connected to the other of the straight-arm support rods 1. A mounting sleeve 8 is provided between the connecting rod 7 and the straight-arm support rod 1, and the mounting sleeve 8 is fixed to the straight-arm support rod 1, and the end of the connecting rod 7 is fitted into the mounting sleeve 8 and fixedly connected to the mounting sleeve 8. This makes it easy to fixedly connect the two straight-arm support rods 1 together through the connecting rod 7, and the provision of the mounting sleeve 8 improves the stability and structural strength of the connection.

The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. It is clear to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be embodied in other specific forms without departing from the spirit or essential characteristics of the present application.
