Description

Technical Field

[0001] This utility model relates to the field of bicycles, and in particular to a bicycle with a warning light. Background Technology

[0002] Bicycles are a green and environmentally friendly mode of transportation, typically consisting of two wheels and propelled by human pedaling. They serve not only as a means of transportation and cargo transport but also as a tool for physical exercise and athletic competition. Due to changing work patterns, many people are in a sub-healthy state due to prolonged sitting, leading more and more people to choose cycling for exercise. Cycling is a full-body workout that effectively improves cardiovascular function, strengthens muscles, and boosts the body's immunity. Long-term cycling can also prevent and improve various chronic diseases. Cycling is a periodic aerobic exercise that burns a significant amount of energy and fat while building toned muscles. The outdoor environment while cycling is uplifting, helping to relieve stress and improve mood—a rare "mental spa" in modern society. Furthermore, cycling can improve sleep quality.

[0003] Many people choose to cycle at night because it's cooler after get off work and at night, making it suitable for high-intensity exercise. Parks are also a popular choice for cycling due to their flat roads, beautiful environment, and fresh air. However, cycling in parks can be challenging because dense trees can create dim lighting in some areas, resulting in insufficient light from bicycle lights and ineffective reflectors, potentially leading to collisions. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a bicycle with a warning light, which can solve the following technical problems: when riding in a park, due to the dense trees, some areas are dimly lit, the bicycle lights are not bright enough, and the reflectors are not reflective enough, which can lead to bicycle collisions and other situations.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bicycle with a warning light, including a seat post mounted on the bicycle and a rotating rod rotatably connected to the seat post. One end of the rotating rod is fixedly connected to a rear frame, and a switch cylinder is provided inside the rear frame. The switch cylinder can be switched to an on or off state according to the tilt angle of the rear frame. A light frame is integrally formed at the front end of the rear frame, and an LED light group is fixed inside the light frame. A rechargeable battery pack is fixed inside the rear frame.

[0006] As a preferred embodiment of this utility model, a clamp is fixed to the outer side of the seat rod, and a connecting rod is fixed to the outer side of the clamp. The connecting rod and the rotating rod are connected by a bolt group.

[0007] As a preferred embodiment of this utility model, guide strips are fixed on both sides of the rotating rod near the rear frame, an L-shaped locking strip is provided on one side of the rear frame to engage with the guide strips, a limit block is fixed on one side of the rear frame, an installation groove is provided on the top surface of the rotating rod, a guide rod is horizontally placed inside the installation groove, an L-shaped movable locking block is sleeved on the outside of the guide rod, a spring is sleeved on the outside of the guide rod, and a lever block is provided on the top surface of the rotating rod to be fixedly connected to the L-shaped movable locking block.

[0008] As a preferred embodiment of this utility model, the top surface of the lever is provided with anti-slip texture.

[0009] As a preferred embodiment of this utility model, the inside of the switch cylinder is provided with a first copper sheet and a second copper sheet, with a certain gap between the first copper sheet and the second copper sheet, and the inside of the switch cylinder is provided with a movable conductive copper block.

[0010] In a preferred embodiment of this invention, one electrode of the rechargeable battery pack is connected to the second copper sheet via a wire, the other electrode is connected to the LED light assembly via a wire, and the LED light assembly is connected to the first copper sheet via a wire.

[0011] As a preferred embodiment of this utility model, a heat sink is provided on the outer side of the LED light assembly, and the heat sink extends to contact the light frame.

[0012] As a preferred embodiment of this utility model, the front end of the lamp frame is connected to a pressure cap via a plastic connecting piece, and the pressure cap is fixed to the lamp frame by a magnet assembly.

[0013] As a preferred embodiment of this utility model, the magnet assembly consists of two magnets that attract each other, one magnet being fixedly connected to the cover and the other magnet being fixedly connected to the lamp frame.

[0014] As a preferred embodiment of this utility model, the charging port of the rechargeable battery pack is located inside the rear frame, and the charging port is sealed by a sealing rubber plug.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0016] 1. By designing a conductive copper block that can slide inside the switch cylinder, when the rear frame is tilted downwards, the conductive copper block will move to a state of contact with the first copper plate and the second copper plate. At this time, the circuit is turned on, and the light of the LED light group will illuminate the ground behind the bicycle rear wheel. It will be observed by people behind through diffuse reflection, without directly shining into their eyes and affecting their observation of the road ahead. When the rear frame is lifted upwards, the conductive copper block will slide down due to gravity, so that the conductive copper block will not contact the first copper plate, thereby turning off the light of the LED light group, thus achieving the function of warning pedestrians behind.

[0017] 2. By designing an L-shaped locking strip that engages with the guide strip, the rotating rod is connected to the rear frame. The rear frame is prevented from moving further down by a limiting block placed above the rotating rod. At the same time, the connection between the rear frame and the rotating rod is fixed by the engagement of the L-shaped moving locking block and the limiting block, while also facilitating the disassembly of the rear frame and the rotating rod.

[0018] 3. By designing a plastic connecting piece between the cover and the lamp frame, the cover can be flipped. Through the action of the magnet group, the cover and the lamp frame are fixedly connected. The cover can also hold a card with a certain pattern between the cover and the lamp frame. After the LED light group shines on the card, it forms a light with a certain shape on the ground, which increases the aesthetics. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort. Example 1

[0028] Please refer to Figure 1 , Figure 2 Figure 3 and Figure 6 As shown, this utility model provides a bicycle with a warning light, including a bicycle 1. The bicycle 1 is provided with a seat post 2. A clamp 3 is fitted on the outside of the seat post 2, which can change the position of the clamp 3 on the outside of the seat post 2 and fix the clamp 3 on the outside of the seat post 2. A connecting rod 4 is fixed on the outside of the clamp 3. The connecting rod 4 and the rotating rod 10 are connected by a bolt group. The end of the rotating rod 10 connected to the connecting rod 4 is U-shaped and fits on the outside of the connecting rod 4. After the rotating rod 10 and the connecting rod 4 are connected by the bolt group, the angle between the connecting rod 4 and the rotating rod 10 will not change when no large external force is applied. After a large external force is applied, the angle between the connecting rod 4 and the rotating rod 10 can be changed.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the other end of the rotating rod 10 is fixed to a rear frame 9. A switch cylinder 12 is fixed to the middle of the inner side of the rear frame 9. A rechargeable battery pack 13 is fixed to the inner wall of the rear frame 9. The charging head of the rechargeable battery pack 13 is embedded inside the rear frame 9 and sealed by a sealing rubber plug 14 fixed to the outside of the rear frame 9. The other end of the rear frame 9 is integrally formed with a lamp frame 8. An LED light group 6 is fixed to the inner side of the lamp frame 8. Several heat sinks 11 are fixed to the outer side of the LED light group 6. The heat sinks 11 extend outward to contact the lamp frame 8, so that the heat generated by the LED light group 6 when it is working is conducted to the lamp frame 8 for heat dissipation. Since the lamp frame 8 and the rear frame 9 can be designed to be integrally formed, an opening can be provided on one side. After all parts are fixed, the device can be sealed to prevent the warning device from being damaged by sudden rain during riding.

[0030] like Figure 6 As shown, the switch cylinder 12 has a hollow structure. A groove is provided on the inner wall of the end of the switch cylinder 12 near the LED light group 6. A first copper sheet 21 and a second copper sheet 23 are provided in the groove. A certain gap is left between the first copper sheet 21 and the second copper sheet 23. A conductive copper block 22 is provided inside the switch cylinder 12. The conductive copper block 22 can slide inside the switch cylinder 12.

[0031] In this circuit, one electrode of the rechargeable battery pack 13 is connected to the second copper sheet 23 by a wire, and the other electrode is connected to the LED light group 6 by a wire. The LED light group 6 is connected to the first copper sheet 21 by a wire, thus forming a complete circuit. The connection or disconnection is determined by the change of the angle of the rear frame 9.

[0032] Specific working principle:

[0033] When in use, press the rear frame 9 downwards to rotate it at a certain angle, so that the LED light group 6 faces the ground behind the rear wheel. At this time, the height of the first copper piece 21 is lower than that of the second copper piece 23. The conductive copper block 22 moves towards the first copper piece 21, so that the conductive copper block 22 is in contact with both the first copper piece 21 and the second copper piece 23, thus connecting the circuit. This allows the light from the LED light group 6 to shine onto the ground behind the rear wheel and be observed by people through diffuse reflection. It will not shine directly into people's eyes and affect their observation of the front. When not in use, rotate the rear frame 9 so that the LED light group 6 faces the ground. At this time, the conductive copper block 22 will move backwards and separate from the first copper piece 21. At this time, the circuit is not connected, and the LED light group 6 will not continue to work. Example 2

[0034] Please refer to Figures 1-7As shown, this utility model provides a bicycle with a warning light, and also includes a guide strip 16. The guide strip 16 is fixed on both sides of the rotating rod 10. An L-shaped locking strip 15 is fixed on the outer side of the rear frame 9. The L-shaped locking strip 15 engages with the guide strip 16. A limiting block 17 is fixed on the outer side of the rear frame 9. The limiting block 17 rests on the top of the rotating rod 10. An installation groove 25 is opened on the top surface of the rotating rod 10. A guide rod 24 is horizontally placed on the inner side of the installation groove 25. An L-shaped movable locking block 18 is sleeved on the outer side of the guide rod 24. A spring 26 is sleeved on the outer side of the guide rod 24. The spring 26 pushes the L-shaped movable locking block 18 towards the rear frame 9 so that the L-shaped movable locking block 18 can engage with the limiting block 17. A lever 19 is provided on the top surface of the rotating rod 10 and is fixed to the L-shaped movable locking block 18. The top surface of the lever 19 is provided with anti-slip texture.

[0035] When it is necessary to separate the rear frame 9 from the rotating rod 10, move the toggle block 19 to move the L-shaped moving block 18, so that the L-shaped moving block 18 will no longer engage with the limit block 17. Pull the rear frame 9 upward to separate the rear frame 9 from the rotating rod 10, so that the warning light can be removed for charging. When it is necessary to connect the rear frame 9 to the rotating rod 10, move the toggle block 19 to move the rear frame 9. After engaging the L-shaped locking strip 15 with the guide strip 16, the limit block 17 will rest on the top of the rotating rod 10. Release the toggle block 19, and the spring 26 will push the L-shaped moving block 18 to engage with the limit block 17, so that the rear frame 9 is connected and fixed to the rotating rod 10. Example 3

[0036] Please refer to Figures 1-6 As shown, this utility model provides a bicycle with a warning light, and also includes a cover 5. The cover 5 is hollow in the middle, allowing the light from the LED light assembly 6 to pass through the cover 5. A plastic connecting piece 7 is provided between the cover 5 and the light frame 8, so that the cover 5 can be flipped. A magnet assembly 20 is provided between the cover 5 and the light frame 8. The magnet assembly 20 consists of two magnets. One magnet is fixedly connected to the cover 5, and the other magnet is fixedly connected to the light frame 8. Through the action of the magnets, the cover 5 can be opened and closed. A light-shielding card with a certain transparent shape can be placed between the cover 5 and the light frame 8. The card is light-transmitting, so that the light shining on the road has a specific shape, which increases the aesthetics. At the same time, the card can shield the LED light assembly 6 to prevent small stones flying from the tires from hitting the LED light assembly 6.
