Description

Technical Field

[0001] This utility model relates to a bicycle, and more particularly to an electric bicycle. Background Technology

[0002] Electric bicycles are a common mode of transportation, widely used in people's daily work and study.

[0003] Existing electric bicycles are equipped with a power source, which drives the rear wheel to rotate, thus propelling the electric bicycle forward. The riding function of existing electric bicycles is basically unusable, and the chain of existing electric bicycles is completely exposed, making it easy for debris to get stuck.

[0004] Furthermore, the power supply of electric bicycles is often installed in the seat area, resulting in a large seat and a bulky overall weight. Utility Model Content

[0005] The purpose of this utility model is to provide an electric bicycle to solve the technical problems existing in the bicycle technology.

[0006] According to one aspect of the present invention, an electric bicycle is provided, including a frame, a first sprocket, a chain, and a second sprocket. One end of the chain is disposed on the first sprocket, and the other end of the chain is disposed on the second sprocket. The chain is arranged in a ring. The upper side of the chain is disposed in the crossbeam of the frame. The crossbeam is arranged laterally and has a receiving space. The upper side of the chain can be arranged laterally in the receiving space and can drive along the lateral space. The frame is also provided with a connecting beam that connects the front of the frame and the crossbeam. A power source is disposed in the connecting beam.

[0007] In some implementations, a buckle plate is provided on the connecting beam, and the buckle plate is detachably connected to the connecting beam. When the buckle plate is removed, the power supply can be extracted from the connecting beam.

[0008] In some embodiments, one end of the buckle plate is provided with a push buckle, one end of which is connected to a spring. The spring is located in the buckle plate and can drive the other end of the push buckle to insert into the connecting beam. Alternatively, when the push buckle is pushed, the other end of the push buckle can disengage from the connecting beam.

[0009] In some embodiments, a cover plate is also provided on the crossbeam. The cover plate is detachably fitted onto the crossbeam, and the cover plate and the crossbeam form an accommodating space. The upper end surface of the cover plate forms a transverse plane.

[0010] In some embodiments, the cover plate is provided with two vertically arranged fixing plates that can be inserted into the crossbeam and can fit against the inner wall of the crossbeam.

[0011] In some implementations, the connecting beam is inclined.

[0012] In some implementations, the rear wheels of the vehicle body have built-in motors that are electrically connected to a power source.

[0013] In some implementations, headlights are provided at the front of the vehicle body.

[0014] The beneficial effects of this utility model are as follows: The upper side of the chain in this utility model can be arranged in the receiving space of the crossbeam and can be transmitted along the horizontal space. The crossbeam can cover the upper side of the chain, which can protect the chain and prevent the chain from contacting the human foot when riding this utility model, thus preventing foot injury. In addition, since the power supply can be set in the connecting beam, the overall structure of the vehicle can be similar to that of a geared bicycle. When the power is not on, it has the climbing function of a geared bicycle. Furthermore, the crossbeam and the connecting beam can form a stable triangular structure, and the crossbeam can be the same as the foot pedal structure of a scooter.

[0015] Furthermore, the power supply in this invention can be located in the connecting beam, and a buckle plate can be installed on the connecting beam. The buckle plate can be removed from the connecting beam to remove and replace the power supply. By placing the power supply in the connecting beam, this invention can be made lighter overall.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Figure 1 and Figure 7 The diagram schematically illustrates the structure of an electric bicycle according to one embodiment of the present invention.

[0027] like Figure 1 and Figure 7 As shown, an electric bicycle includes a frame 1, on which a first sprocket 11, a chain 12, and a second sprocket 13 are mounted. Figure 2 In this design, the right end of the chain 12 is mounted on the first sprocket 11, and the left end of the chain 12 is mounted on the second sprocket 13. The first sprocket 11 can be connected to the pedal, and the second sprocket 13 can be connected to the rear wheel. The pedal can drive the first sprocket 11 to rotate, and the chain 12 can drive the second sprocket 13 to rotate, thus realizing the function of a multi-speed bicycle (the figure shows a multi-speed bicycle; since the structure of a multi-speed bicycle is existing technology, it will not be described in detail in this utility model). The upper side of the chain 12 is located in the crossbeam 14 of the vehicle body 1. The crossbeam 14 is arranged horizontally and has a receiving space. The upper side of the chain 12 can be arranged horizontally in the receiving space and can transmit power along the horizontal space. The vehicle body 1 is also provided with a connecting beam 15, which connects the front of the vehicle and the crossbeam 14. A power supply 152 is installed in the connecting beam 15. Therefore, by setting the connecting beam 15, the vehicle body 1 can be made more stable as a whole. At the same time, the power supply 152 can be installed and hidden in the connecting beam 15, making the vehicle body 1 lighter as a whole.

[0028] like Figures 5-7As shown, in this embodiment, a buckle plate 151 is installed on the connecting beam 15. The buckle plate 151 is detachably connected to the connecting beam 15. When the buckle plate 151 is removed, the power supply 152 can be taken out from the connecting beam 15. Therefore, by installing the buckle plate 151, the connecting beam 15 can be opened, and the power supply 152 can be taken out and replaced with a new power supply. At the same time, after the buckle plate 151 is locked onto the connecting beam 15, the power supply 152 will not fall off the connecting beam 15.

[0029] like Figures 5-7 As shown, in this embodiment, a push buckle 1511 is installed on the upper end of the buckle plate 151, and a spring can be connected to the lower end of the push buckle 1511. The spring is fixedly installed in the buckle plate 151 and is in a compressed state. Without the action of external force, the spring can drive the upper end of the push buckle 1511 to insert into the connecting beam 15. For example, if a slot is provided at the corresponding position of the connecting beam 15, the upper end of the push buckle 1511 can be inserted into the slot, so that the buckle plate 151 and the connecting beam 15 are locked together. Alternatively, after the push buckle 1511 is pushed downward, the upper end of the push buckle 1511 can disengage from the slot of the connecting beam 15, thereby the upper end of the push buckle 1511 leaves the slot of the connecting beam 15, and the push buckle 1511 will not lock the connecting beam 15, so the buckle plate 151 can be removed.

[0030] like Figure 4 As shown, a cover plate 141 is also provided on the crossbeam 14. The cover plate 141 is detachably attached to the crossbeam 14, and the cover plate 141 and the crossbeam 14 form a receiving space. Tools or daily necessities can be placed in the receiving space for convenient temporary use by the electric vehicle. In this embodiment, the upper surface of the cover plate 141 forms a transverse plane, giving the cover plate 141 a planar structure similar to a skateboard. The width of the transverse plane of the cover plate 141 is greater than the width of two feet, allowing the user's feet to be placed on the cover plate 141.

[0031] like Figure 4 As shown, two vertically arranged fixing plates 1411 are integrally formed on the cover plate 141. The fixing plates 1411 can be inserted into the crossbeam 14, and the fixing plates 1411 can fit against the inner wall of the crossbeam 14. Therefore, by the interference fit between the fixing plates 1411 and the crossbeam 14, the cover plate 141 will not detach from the crossbeam 14.

[0032] from Figures 1-3 As can be seen, the connecting beam 15 in this embodiment is inclined. Therefore, the connecting beam 15 can form a triangular structure with the vehicle body 1, and this inclined connecting beam 15 makes the vehicle body 1 more stable as a whole.

[0033] In this embodiment, a motor is built into the rear wheel of the vehicle body 1, and the motor is electrically connected to the power supply 152. The power supply 152 can provide power to the motor, which can be connected to the rear wheel of the vehicle body 1. The motor can drive the rear wheel of the vehicle body 1 to rotate, and can also drive the vehicle body 1 forward.

[0034] In this embodiment, a headlight 16 is installed at the front of the vehicle body 1. The headlight 16 can be used for illuminating the vehicle body 1.

[0035] In this invention, the upper side of the chain 12 can be arranged in the receiving space of the crossbeam 14, and can transmit power along the transverse space. The crossbeam 14 can cover the upper side of the chain 12, which can protect the chain 12 and prevent the chain 12 from contacting the human foot when riding this invention, thus preventing foot injury. In addition, since the power supply 152 can be set in the connecting beam 15, the overall structure of the vehicle body 1 can be similar to that of a geared bicycle. When the power is not on, this invention has the climbing function of a geared bicycle. Furthermore, the crossbeam and the connecting beam 15 can form a stable triangular structure, and the cover plate 141 of the crossbeam 14 can be the same as the foot pedal structure of a scooter.

[0036] Furthermore, the power supply 1 in this utility model can be set in the connecting beam 15, and a buckle plate 151 can be set on the connecting beam 15. The buckle plate 151 can be removed from the connecting beam 15, the power supply can be taken out and replaced with the power supply 152. By setting the power supply 152 at the connecting beam 15, the overall utility model can be made lighter.

[0037] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
