Description

Technical Field

[0001] This utility model relates to supporting components for electric bicycles, and more particularly to a rear tail box for electric bicycles. Background Technology

[0002] 1. Chinese Patent Publication No. CN210618324U discloses a rear box for an electric bicycle with a seat cushion, including a support bracket fixed to the frame of the electric bicycle. The rear box is mounted on the support bracket and consists of a top cover and a base. A seat cushion base plate is mounted on the top of the top cover and is fixed to the top cover of the rear box with fasteners. A leather layer is wrapped around the seat cushion base plate, and a soft padding layer is placed between the leather layer and the seat cushion base plate. A backrest is provided on the rear side of the rear box, and a fixing frame is provided under the backrest and fixed to the support bracket with fasteners. When the top cover of the rear box is open, it can be used to place some miscellaneous items. When the seat cushion is mounted on the rear box and the top cover is closed, it can be used to carry children. The seat cushion is soft and comfortable. The backrest is provided at the rear of the rear box to provide comfort for the rider and to support the back, preventing the rider from leaning backward and falling off during rapid acceleration.

[0003] 2. Chinese Patent Publication No. CN210101852U discloses a rear cargo box for electric vehicles or motorcycles, aiming to address the shortcomings of current motorcycle and electric bicycle rear cargo boxes, which have low strength and are easily damaged in collisions, causing financial losses and personal injury. This utility model includes a lid and a body. The lid is rotatably connected to the body, and a reinforcing groove is provided on the edge where the lid and body meet. A corresponding reinforcing protrusion is provided on the body, and the reinforcing protrusion is inserted into the reinforcing groove. This improves the connection strength between the body and the lid, reducing the probability of damage. The vent notch disrupts the airtightness of the cavity formed between the reinforcing protrusion and the reinforcing groove, making opening smoother and maintaining a consistent feel each time it is opened.

[0004] 3. Chinese Patent Publication No. CN210101852U discloses a multi-functional tail box for electric bicycles, relating to the field of electric bicycle technology. The box includes a body with four symmetrical dampers at its bottom interior. Each damper's top is connected to a storage box. Two symmetrical fixing rods are located on both sides of the box's interior, with a connecting rod connected to one side of each. Two symmetrical sliding rods and shock-absorbing springs are fitted onto the outside of the connecting rods. A movable plate is connected to the top of the sliding rods, and a mounting plate is connected to the top of the movable plate. When vibration occurs, the dampers act as the first layer of buffering. Then, the storage box moves the movable plate, and the sliding rods compress the shock-absorbing springs, providing a second layer of buffering, thus cushioning the items inside the tail box. Rainwater flows into the chamber through a through-hole. By rotating and unscrewing the cover, rainwater flows out through a telescopic hose, reducing the amount of rainwater inside the tail box and preventing long-term moisture damage.

[0005] 4. Chinese Patent Publication No. CN113501068A discloses a small electric bicycle rear seat box, including a storage box shell, a storage box cover, a backrest body, a triangular fixing plate, a first straight plate, an arc-shaped plate, and a second straight plate. The lower end of the storage box shell and the lower end of the storage box cover are rotatably connected. The triangular fixing plate is located at the middle of one end of the storage box shell. The first straight plate is located at the lower end of the triangular fixing plate. One end of the arc-shaped plate is connected to the lower end of the first straight plate. One end of the second straight plate is connected to the other end of the arc-shaped plate. The backrest body is located at the end of the storage box shell where the triangular fixing plate is located. The triangular fixing plate is located between the backrest body and the storage box shell. The second straight plate is provided with mounting screw holes.

[0006] Electric bicycles have become increasingly popular due to their convenience, low cost, high efficiency, ability to avoid traffic congestion, and long riding range. However, collisions between electric bicycles and trucks / cars are causing more and more traffic accidents. Currently, electric bicycles rely on a red rear light for nighttime visibility; however, this light only illuminates when the headlight is on, and its brightness is low. The light is also small, and some become covered in dust after a period of use, further reducing visibility. This poses a significant danger for electric bicycle riders at night on national highways, provincial highways, urban expressways, and curved roads, where trucks and cars travel at high speeds and most lack dedicated electric bicycle lanes. Adding a separate warning flasher to the rear of the electric bicycle is difficult and troublesome, requires careful power connection, and must also consider waterproofing and aesthetics.

[0007] The aforementioned patent discloses that the rear trunk of existing electric autonomous vehicles is only used for carrying items, and does not have a warning flasher or a power source for the warning flasher. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a rear box for an electric bicycle with a reasonable structural design, a built-in flashlight to improve travel safety, and a portable power supply to power the flashlight for convenient charging.

[0009] The solution to the above technical problem is as follows:

[0010] A rear box for an electric bicycle includes a lower half-box base, an upper half-box cover, a hinge device, and a power bank. The interior of the lower half-box base is an open lower half-box cavity, and the interior of the upper half-box cover is an open cover cavity. A hinge device connects the rear top of the lower half-box base and the rear bottom of the upper half-box cover. The upper half-box cover is flip-open and connected to the top of the lower half-box base via the hinge device. A power connection device is fixed to the inner wall of the lower half-box cavity and is detachably connected to the power bank. A flashlight with a power switch is fixed through the rear wall of the lower half-box base and connected to the power connection device via a wire.

[0011] The beneficial effects of this utility model's rear box for electric bicycles are as follows: This product mainly facilitates nighttime electric bicycle travel, and is particularly suitable for riding on national highways, provincial highways, urban expressways, and the aforementioned winding roads. The flashing light can illuminate from the rear of the electric bicycle, serving as a warning and making it easier for trucks and cars on the road to identify moving vehicles ahead from a distance, thus encouraging safer driving. The portable power bank supplies power to the flashing light through a power connection device. During use, when the portable power bank runs out of power, it can be removed from the power connection device and taken home to charge. After fully charging, it can be returned to the rear box and connected to the power connection device to conduct power. When needed, the flashing light is activated by operating the flashing light switch, and turned off by operating the flashing light switch when not in use. It is convenient for users to use and charge. In case of emergency, it can also be removed to charge a mobile phone. Attached Figure Description
