Description

Technical Field

[0001] This utility model relates to the field of electric bicycles, specifically to a safety taillight for electric bicycles. Background Technology

[0002] Bicycles typically have taillights mounted on their mudguards. When car lights or streetlights shine on these taillights, they reflect bright light, thus ensuring safety. Reflectors are also frequently installed on bicycle wheels and frames; their main structure is a reflector plate, serving both decorative and safety purposes.

[0003] Existing electric bicycle taillights are mounted on a bracket at the rear of the vehicle using bolts. However, the taillight angle cannot be adjusted according to the rider's needs during installation. Adjusting the taillight angle ensures that the light does not directly shine into the eyes of the rider of following vehicles, causing glare. Furthermore, the taillights only illuminate vehicles approaching from behind and cannot illuminate vehicles approaching from the sides. Therefore, it is necessary to solve the problems of existing electric bicycle taillights not being able to adjust the taillight angle according to the rider's needs during installation, and only being able to illuminate vehicles approaching from behind and not vehicles approaching from the sides.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a safety taillight for electric bicycles.

[0026] This utility model provides, for example Figure 1-4The safety taillight for an electric bicycle shown includes a U-shaped mounting bracket 1. Support rods 2 are fixedly connected to both ends of the U-shaped mounting bracket 1. Support sleeves 3 are rotatably connected to the walls of the support rods 2. A friction limiting mechanism that engages with the support sleeves 3 is provided on the side wall of the U-shaped mounting bracket 1. A protective shell 4 is fixedly connected to the other end of the support sleeve 3. An arc-shaped lamp housing 5 is fixedly connected to the side wall of the protective shell 4 via a snap-fit ​​mechanism. A control component 6 is fixedly connected to one end of the arc-shaped lamp housing 5. A connecting cable 7 is fixedly connected to one end of the control component 6. A turn signal 8 is fixedly connected to the top of the arc-shaped lamp housing 5. LED light strips 9 are fixedly connected to the cavities of both the arc-shaped lamp housing 5 and the turn signal 8. Both ends of the LED light strips 9 are electrically connected to the control component 6. An arc-shaped lamp cover 10 is fixedly connected to the side wall of the arc-shaped lamp housing 5, and a regular lamp cover 11 is fixedly connected to the side wall of the turn signal 8. The U-shaped mounting bracket... The bracket 1 facilitates the installation and connection of the taillight to the vehicle body. The support sleeve 3, which rotates on the support rod 2, allows for angle adjustment of one end of the taillight to suit the rider's needs. The arc-shaped lamp housing 5, connected to the protective shell 4 via a snap-fit ​​mechanism, facilitates disassembly, maintenance, and replacement, and allows for easy reinstallation. The connecting cable 7 at one end of the control component 6 allows for control of the taillight by connecting to the corresponding parts. The turn signal 8 provides turn indication. The arc-shaped lamp housing 5 extends the lateral range, effectively alerting vehicles approaching from both sides. This design addresses the problems of existing electric bicycle taillights, which cannot adjust the taillight angle according to the rider's needs during installation and only illuminate vehicles behind, failing to illuminate vehicles approaching from both sides.

[0027] In order to limit the position of the support sleeve 3 after rotation adjustment, such as Figure 3 As shown, the friction limiting mechanism includes a first annular damping pad 12, a first screw 13, a second annular damping pad 14, and an auxiliary slide rod 15. The first annular damping pad 12 is fixedly connected to the inner wall of one end of the U-shaped mounting bracket 1. The first screw 13 is threadedly connected to the inner wall of the other end of the U-shaped mounting bracket 1 via a threaded opening. The second annular damping pad 14 is rotatably connected to the first screw 13. The auxiliary slide rod 15 is slidably connected to the inner wall of the other end of the U-shaped mounting bracket 1 via an opening. One end of the auxiliary slide rod 15 is connected to the second annular damping pad 14. One end of the support sleeve 3 is fixedly connected to the side wall of the support sleeve 4. The two end side walls of the support sleeve 3 are respectively engaged with the first annular damping pad 12 and the second annular damping pad 14. The first screw 13, which is set in the threaded opening of the side wall of the U-shaped mounting bracket 1, drives the second annular damping pad 14 at one end to move by rotating. The second annular damping pad 14 moves towards the first annular damping pad 12, clamping the support sleeve 3 and limiting it by friction. The auxiliary slide rod 15 is used to cooperate with the first screw 13 to make the second annular damping pad 14 move linearly.

[0028] To facilitate the disassembly and reinstallation of the curved lamp housing 5, such as Figure 1-4 As shown, the snap-fit ​​mechanism includes a snap-fit ​​interface 16, a snap-fit ​​block 17, a corresponding insertion hole 18, a second screw 19, and a nut 20. The inner side wall of the protective shell 4 has a snap-fit ​​interface 16, and the snap-fit ​​block 17 is snapped in place. The side wall of the arc-shaped lamp shell 5 is fixedly connected to the snap-fit ​​block 17. The surfaces of the protective shell 4 and the snap-fit ​​block 17 have corresponding insertion holes 18, and the second screw 19 is inserted in place. One end of the second screw 19 passes through the corresponding insertion hole 18 and is threadedly connected to the nut 20. The snap-fit ​​block 17, which is located on the side wall of the arc-shaped lamp shell 5, is snapped in place by inserting it into the snap-fit ​​interface 16. The second screw 19, which passes through the corresponding insertion hole 18 of the arc-shaped lamp shell 5 and the snap-fit ​​block 17, is threadedly connected to the nut 20, thereby facilitating the disassembly and reinstallation of the arc-shaped lamp shell 5.

[0029] To alert vehicles approaching from behind and to the sides when the battery is low, such as Figure 1 , 2 As shown in Figure 4, both the curved lampshade 10 and the ordinary lampshade 11 have a reflective coating on their surfaces. The reflective coating is used to alert vehicles approaching from behind and to the sides when the battery is low.

[0030] To facilitate manual rotation of the first screw 13, such as Figure 3 As shown, a rotating handle 21 is fixedly connected to the other end of the first screw 13, which facilitates manual rotation of the first screw 13.

[0031] To facilitate the installation of the U-shaped mounting bracket 1 onto the vehicle body, such as Figure 1 and 3 As shown, mounting screws 22 are fixedly connected to both ends of the side wall of the U-shaped mounting bracket 1. The mounting screws 22 facilitate the installation of the U-shaped mounting bracket 1 to the vehicle body.

[0032] How to use:

[0033] During installation, the U-shaped mounting bracket 1 is installed at the rear of the vehicle body using mounting screws 22 and nuts. The taillights are controlled by connecting the connecting cable 7 at one end of the control component 6 to the corresponding part. The first screw 13 is rotated by turning the handle 21, which causes the second annular damping pad 14 to move in the opposite direction, causing the support sleeve 3 to lose its limit. The angle of the support sleeve 3 can be directly adjusted by rotating it. After adjustment, the first screw 13 is rotated by turning the handle 21, which causes the second annular damping pad 14 to move and cooperate with the first annular damping pad 12 to clamp the support sleeve 3. The friction force is used to fix and limit the position. The arc-shaped lamp housing 5 is designed to extend the lateral range, which is convenient for warning vehicles coming from both sides.
