Description

Technical Field

[0001] The present application relates to the technical field of bicycle accessories, and in particular to a bicycle rear light. Background Art

[0002] In recent years, due to environmental protection and traffic issues, bicycles have once again become a favorite means of transportation and fitness for residents, and the focus of the bicycle industry is shifting from traditional means of transportation to sports, mountain, and leisure types. When riding a bicycle at night, especially in places without street lighting, a rear light is installed at the rear end of the bicycle to warn the following vehicles. Traditional rear lights are just simple reflectors that do not emit light themselves, but through optical principles, when the light shines on them at night, they reflect light as a reminder. However, due to the limited brightness of the reflection, it is difficult for the following vehicle to detect it from a distance, which greatly restricts the safety of people riding bicycles. Therefore, a rear light with high brightness and the ability to switch light brightness and lighting mode is needed to ensure people's safe travel.

[0003] Related prior art, such as Chinese patent application "Bicycle rear light", application number: CN202122457343.9, discloses a housing, a bracket and a circuit board, wherein the bracket is connected to the rear side of the housing, an opening is provided on the front side of the housing, the circuit board is fixed inside the housing, a battery electrically connected to the circuit board is fixed on the front side of the circuit board, a button for triggering a key on the circuit board is embedded at the upper end of the housing, a charging interface electrically connected to the circuit board is embedded at the lower end of the housing, a number of LED lamp beads are installed on the front side of the circuit board, a light guide cover and a light-transmitting cover are sequentially arranged from the inside to the outside at the opening of the housing, a number of positioning grooves distributed from top to bottom are arranged on the left and right sides of the light guide cover, a positioning block for one-to-one engagement with each positioning groove is arranged on the inner wall of the housing, the light guide cover is pressed against the housing through the light-transmitting cover, and the light-transmitting cover is bonded to the housing. This patent application can ensure its own luminous effect and can ensure the warning effect to the rear vehicles.

[0004] The rear light of the above patent application needs to be disassembled from the bicycle when the battery is exhausted and needs to be charged, which makes the stable rear light inconvenient to use. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide a bicycle rear light, to further improve the structure of the bicycle rear light, so that the light and the bracket structure are detachable, so that the user can charge the light or replace the power supply battery conveniently.

[0006] The technical solution adopted in the present application is: a bicycle rear light, including a light and a bracket, the bracket including a lower bracket connected to the bicycle, and an upper bracket with a U-shaped structure, the middle part of the light is adapted to the structure of the upper bracket, the light is embedded into the upper bracket from the opening end of the upper bracket and is clamped with the bracket, a power supply battery, a control device and a light-emitting component are installed in the light, the power supply battery provides power for the control device and the light-emitting component, and the control device is electrically connected to the light-emitting component to control the operation of the light-emitting component.

[0007] Compared with the prior art, the advantage of the present application is that the headlight and the bracket of the present application are detachably connected, so the bracket can be directly fixed on the bicycle, and the headlight can be installed on the bracket according to the needs, or removed from the bracket for separate use or operation. Specifically, the present application adopts an upper bracket with a U-shaped structure, and the middle part of the headlight is adapted to the structure of the upper bracket in accordance with the corresponding upper bracket, so that the headlight can be well connected to the upper bracket. Then, the present application designs the installation of power supply batteries, control devices and light-emitting components in the headlight, and all electronic components are concentrated in the headlight. Then, when the user needs to charge or replace the power supply battery, he only needs to remove the headlight from the bracket without moving the bracket. When the demand for the headlight is met, the user only needs to clip the headlight into the upper bracket. The structural setting of the present application greatly facilitates the user to charge or replace the power supply battery of the headlight, and the present application can even remove the headlight for separate use.

[0008] In some embodiments of the present application, the cross-section of the headlight is a runway-shaped structure, and two limiting ridges are arranged on the side where the long side of the headlight is located. The two limiting ridges are arranged parallel to each other, and the distance between the two limiting ridges on the same side of the headlight just accommodates the end of the upper bracket.

[0009] In the vehicle lamp, a limiting rib structure is made on the side of the vehicle lamp. After the vehicle lamp and the upper bracket are installed, the two ends of the upper bracket of the U-shaped structure will be clamped on the two sides of the vehicle lamp. The two limiting ribs will effectively limit the relative displacement between the vehicle lamp and the upper bracket, so that the vehicle lamp can be stably clamped on the bracket.

[0010] In some embodiments of the present application, the car light includes a top surface and a bottom surface, a power supply battery is arranged on the side of the car light close to the bottom surface, a control device is arranged at both ends of the power supply battery, and a light-emitting component is installed near the top surface of the car light.

[0011] Arranging the power supply battery, control device and light-emitting component in the headlight as described above can effectively utilize the internal space of the headlight, and the above arrangement is very reasonable and suitable for user use. Specifically, the power supply battery in this application is a lithium battery.

[0012] In some embodiments of the present application, the control device includes a first PCB board and a second PCB board respectively arranged at the two ends of the rechargeable battery, the first PCB board is provided with a USB charging interface and an indicator light group, the USB charging interface and the indicator light group are exposed on the bottom side of the car light and covered by a dustproof pad, the second PCB board is provided with a switch, and the corresponding setting button on the bottom side of the car light is connected to the switch.

[0013] In this application, in order to make it more convenient for users to use, the capacity of the power supply battery in the headlight should be as large as possible, which will correspondingly cause the volume of the power supply battery to be larger, while at the same time ensuring that the overall structure of the headlight is not too large. Therefore, this application splits the control device into a first PCB board and a second PCB board, and installs them at both ends of the rechargeable battery respectively, which can fully utilize the space in the headlight. Correspondingly, the USB charging interface, indicator light group and buttons that need to interact with the user are also arranged at the two ends of the bottom surface of the headlight.

[0014] In some embodiments of the present application, the light-emitting component includes an aluminum substrate and a plurality of COBs regularly installed on the aluminum substrate. The aluminum substrate as a whole has a runway-shaped plate structure adapted to the lamp body, the middle portion of the aluminum substrate is a plane, and the two ends are curved surfaces bent toward the bottom side.

[0015] Preferably, the COB in this application is a red COB, which emits red light. The structural setting of the aluminum substrate effectively increases the illumination angle of the light-emitting component, so that the lamp body has a wide-angle effect.

[0016] In some embodiments of the present application, the top surface of the headlight is a curved surface structure adapted to the aluminum substrate, and the top surface of the headlight is made of a transparent material. Specifically, the top surface of the headlight is made of a red transparent material, and the headlight will emit a red warning light when working with the light-emitting component in the headlight.

[0017] In some embodiments of the present application, a brake sensor is installed in the headlight, and the brake sensor is connected to the control device. By adding a brake sensor, the product of the present application realizes the function of automatically sensing the brake and lighting up the warning light. Specifically, when the bicycle is sensed to suddenly slow down, the light-emitting component in the headlight will emit ultra-high brightness for 3 seconds and then return to the original state. In the present application, the brake sensor is a direct application of the existing technology.

[0018] In some embodiments of the present application, the bottom surface of the vehicle lamp is a planar structure, and the bottom surface of the vehicle lamp is partially attached to the inner bottom surface of the upper bracket.

[0019] In some embodiments of the present application, silicone pads are attached to the inner bottom surface of the upper bracket and the inner wall surfaces on both sides connected to the inner bottom surface, and the upper bracket contacts the bottom surface and side surface of the headlight through the silicone pads. In order to firmly clamp the headlight, the headlight is tightly mounted on the upper bracket, so adding a silicone pad structure can effectively increase the friction between the headlight and the upper bracket to ensure the stability of the headlight after installation. Secondly, silicone is easier to deform and has a better service life.

[0020] In some embodiments of the present application, a magnet assembly is installed in the headlight, and the magnet assembly is embedded in the bottom surface of the headlight. The outer shell of a bicycle is usually made of a metal material that can be magnetically attracted. Then, a magnet assembly is added to the headlight of the present application, and the user can remove the headlight separately and attach it to any position of the bicycle outer shell to serve as a warning.
