[0043] Referring to FIG. 1 , an embodiment of the present invention provides a follow-up lamp assembly, including a base frame 100 , a headlight module 200 , a driving assembly 300 and a connecting assembly 400 , wherein:

[0044] The headlight module 200 is arranged on one side of the base frame 100 and is rotatably connected to the base frame 100; the driving assembly 300 is arranged on the other side of the base frame 100 and is connected to the headlight module 200. Under the drive of the driving assembly 300, the headlight module 200 rotates around the first direction axis; the connecting assembly 400 is arranged between the headlight module 200 and the base frame 100, and is used to connect the headlight module 200 and the base frame 100.

[0045] The motorcycle body will tilt when turning. When the motorcycle body tilts, the headlight assembly rotates under the drive of the driving assembly 300 to adapt to the angle of the body tilt, ensuring that the lighting area and light path remain unchanged, which helps to improve the visibility and safety of night driving, reduce the lighting dead angle or visual blind spot caused by the body tilt, and reduce the risk of accidents. The follow-up light group can automatically adjust the illumination angle according to the tilt angle of the motorcycle body, and has strong adaptability. Whether the motorcycle is driving in a straight line or turning around a corner, the light can maintain the appropriate illumination position to ensure that the road conditions ahead are clearly visible during driving. Specifically in this embodiment, the first direction is the forward direction of the vehicle, and the axis of the tilt generated when the motorcycle turns is parallel to the forward direction. Therefore, the headlight module 200 only needs to deflect along the axis that is also parallel to the forward direction to maintain the lighting effect.

[0046] The connecting assembly 400 is used to connect the headlight module 200 and the base frame 100, and can enhance the structural stability of the entire light assembly. During the driving of the motorcycle, there may be bumps, vibrations, etc. The stable connection of the connecting assembly 400 can ensure that the light assembly will not loosen or shift due to vibration, thereby improving the reliability and stability of the entire light assembly. In addition, the design of the connecting assembly 400 can make the disassembly and maintenance of the light assembly more convenient, saving maintenance time and cost.

[0047] Referring to FIG. 2 , in one embodiment, the connecting assembly 400 includes a bearing 410 and a transmission member 420 . The bearing 410 is disposed on the base frame 100 . The transmission member 420 passes through the bearing 410 and is connected to the headlight module 200 . The transmission member 420 is also used to engage the driving assembly 300 to enable the driving assembly 300 to drive the headlight module 200 .

[0048] The bearing 410 is arranged on the base frame 100, and its main function is to provide support and rotation support. By arranging the bearing 410 on the base frame 100, the connection between the transmission member 420 and the headlight module 200 has a stable rotation axis and can withstand the pressure during rotation, thereby ensuring the normal operation of the follow-up light group. The transmission member 420 passes through the bearing 410 to connect with the headlight module 200, and is used to engage the drive assembly 300 to achieve the driving of the headlight module 200 by the drive assembly 300. The design of the transmission member 420 enables the drive assembly 300 to drive the headlight module 200 through the transmission member 420, and the stability and stability during the driving process are guaranteed by the support of the bearing 410. In this embodiment, the connecting assembly 400 plays the role of connection and transmission, so that the drive assembly 300 can effectively drive the headlight module 200 and realize the function of the follow-up light group.

[0049] Referring to FIG. 3 , in one embodiment, the driving assembly 300 includes a driving motor 310 and a driving gear 320, wherein the driving motor 310 is connected to the driving gear 320, and the driving gear 320 is meshed with the transmission member 420 for transmission. The driving motor 310 is the power source of the entire follower lamp assembly, and is responsible for providing driving force to realize the rotation of the headlight module 200. The driving motor 310 can be an electric motor, which is powered by a power supply, and its rotation direction and speed are controlled by a control system. The driving gear 320 is a transmission element connecting the driving motor 310 and the transmission member 420, one end of which is connected to the driving motor 310, and the other end is meshed with the transmission member 420 for transmission. The driving gear 320 is a single gear in this embodiment, and through the rotation of the driving motor 310, the driving gear 320 drives the transmission member 420 to realize transmission. The design of the driving gear 320 needs to match the transmission member 420 to ensure smooth and stable transmission. The driving assembly 300 drives the headlight module 200 through the driving motor 310 and the driving gear 320, so that the follow-up light group has high flexibility and controllability, and can adjust the lighting angle and direction according to driving needs, thereby improving the safety and comfort of the motorcycle during driving.

[0050] In one embodiment, the bearing 410 includes a rotating part and a fixed part, the fixed part is arranged around the rotating part, and the rotating part is configured to be able to rotate relative to the fixed part around an axis parallel to the first direction; the fixed part is connected to the base frame 100, and the rotating part is connected to the transmission member 420. Specifically in this embodiment, the fixed part is the outer ring of the bearing 410, and the rotating part is the inner ring of the bearing 410. It can be understood that the fixed part is arranged on the periphery of the rotating part, and the fixed part and the rotating part are rotatably connected, and then the bearing 410 is arranged on the hole wall of the through hole opened on the base frame 100, that is, the outer side wall of the fixed part away from the rotating part is fixedly connected to the hole wall of the through hole, and correspondingly, the inner side wall of the rotating part away from the fixed part is fixedly connected to the part of the transmission member 420 extending into the through hole, so that the driving member can drive the transmission member 420 to rotate relative to the base frame 100 around an axis parallel to the first direction, and drive the headlight module 200 to rotate around an axis parallel to the first direction.

[0051] Referring to FIGS. 2 to 5 , in one embodiment, the transmission member 420 includes at least one driven gear, and a plurality of first protrusion structures 421 are provided on the side where the driven gear contacts the rotating part, and the plurality of first protrusion structures 421 are arranged according to a preset rule; the driven gear and the rotating part are interference fit through the first protrusion structures 421. The driven gear is a part of the transmission member 420, and is used to transmit driving force to realize the rotation of the headlight module 200. The driven gear is meshed with other gears (such as the driving gear 320) for transmission. Specifically in this embodiment, the number of the driven gear is one, and it is assembled and connected with the heat sink of the headlight module 200. The design feature of the driven gear is that a plurality of first protrusion structures 421 are provided on the side where the driven gear contacts the rotating part, that is, a plurality of protrusions are provided on the side of the boss on the driven gear that contacts the inner ring of the bearing 410, and these protrusion structures are located on the side where the driven gear contacts the rotating part, and are arranged according to a preset rule. The present embodiment does not limit the specific shape of the first protruding structure 421. The arrangement of several first protruding structures 421 can be adjusted according to design requirements. In the present embodiment, they are arranged at equal intervals around the side of the boss. The first protruding structure 421 is used to achieve an interference fit between the driven gear and the rotating part. Interference fit is a commonly used fitting method in design engineering, which means that the fitting clearance between parts is smaller than the size of the parts. In this embodiment, the inner diameter of the rotating part of the bearing 410, i.e., the inner ring, is smaller than the outer diameter of the connecting part between the driven gear and the rotating part. The interference fit between the first protruding structure 421 of the driven gear and the rotating part improves the connection firmness and transmission efficiency between the transmission member 420 and the rotating part, making the rotation of the follower lamp group more stable and reliable, reducing the difficulty of component processing and assembly.

[0052] Referring to FIG. 2 , in one embodiment, a plurality of second protrusion structures 110 are provided on the side of the base frame 100 in contact with the fixed part, and the plurality of second protrusion structures 110 are arranged according to a preset rule; the base frame 100 and the fixed part are interference fit through the second protrusion structures 110. The base frame 100 is the supporting structure of the entire follow-up lamp assembly, and the fixed part is a part of the bearing 410, which is responsible for supporting the rotating part and connecting with the base frame 100. In this embodiment, a plurality of second protrusion structures 110 are provided on the side of the base frame 100 in contact with the fixed part, and the design of these second protrusion structures 110 is similar to the first protrusion structure 421 between the transmission member 420 and the rotating part, but is used here for the connection between the base frame 100 and the fixed part. This embodiment does not limit the specific shape of the second protrusion structure 110, and the arrangement of the plurality of second protrusion structures 110 can be adjusted according to the design requirements. In this embodiment, they are arranged at equal intervals on the inner wall surface of the through hole in contact with the fixed part of the base frame 100. The second protruding structure 110 of the base frame 100 and the fixing part achieve an interference fit, that is, the spacing formed by the second protruding structure 110 of the base frame 100 is slightly smaller than the outer circumference of the fixing part, resulting in a certain pressure and tight connection between them. This design can ensure the stability of the connection, while reducing the gap during assembly and reducing the difficulty of assembly.

[0053] Referring to FIGS. 2 to 5 , in one embodiment, the base frame 100 has a first accommodating chamber 120 suitable for accommodating the driving assembly 300, and a limiting structure 130 is provided at the opening of the accommodating chamber, and the limiting structure 130 is suitable for limiting the movement of the driving gear 320 away from the driving motor 310. The accommodating chamber has a space suitable for the size of the driving assembly 300, and is used to accommodate the driving assembly 300, including the driving motor 310 and the driving gear 320. The accommodating chamber is located on one side of the base frame 100 to ensure that the driving assembly 300 can be firmly installed on the base frame 100. When the driving gear 320 is affected by external forces or other factors, it may move away from the driving motor 310, resulting in separation from the driving motor 310. The design of the limiting structure 130 abuts against the end face of the driving gear 320 during the process of the driving gear 320 separating from the driving motor 310, preventing it from separating from the driving motor 310, and ensuring the stability and reliability of the transmission. Specifically in this embodiment, the limiting structure 130 is a limiting rib disposed on the opening of the first accommodating cavity 120 , and the limiting rib spans the opening of the first accommodating cavity 120 , thereby limiting the driving gear 320 .

[0054] Referring to FIG. 2 and FIG. 5 , in one embodiment, the connection assembly 400 further includes a stopper 430, which is connected to the base frame 100 by bolts, and the stopper 430 abuts against the fixing portion, and is suitable for limiting the movement of the bearing 410 in the first direction. Specifically in this embodiment, the stopper 430 is a bearing 410 stopper gasket, which is assembled on the headlight bracket by bolts to press the bearing 410. The bearing 410 stopper gasket is a specially designed gasket, which functions to limit the movement of the bearing 410 in the first direction. The bearing 410 stopper gasket is connected to the base frame 100 by bolts, and one side abuts against the bearing 410. This design ensures that the bearing 410 stopper gasket can be tightly combined with the headlight bracket and can accurately limit the movement of the bearing 410 in the first direction. When the bearing 410 is subjected to external force or vibration, it may produce unnecessary movement in the first direction. The design of the bearing 410 stopper gasket can ensure that the bearing 410 is subjected to appropriate pressure and prevent it from moving too much in the first direction, thereby ensuring the stability and reliability of the connection.

[0055] Referring to FIG. 5 , in one embodiment, the driven gear is connected to the headlight module 200 by bolts, and the end face of the driven gear abuts against the rotating part; the driven gear, the limit member 430 and the base frame 100 together form a second accommodating cavity suitable for accommodating the bearing 410, and under the action of the bolts, the driven gear and the limit member 430 have a tendency to move closer to each other.

[0056] The driven gear is connected to the headlight module 200 by bolts, specifically, the driven gear is connected to the rear of the headlight module 200, i.e., the radiator. The end face of the driven gear abuts against the rotating part, so that the inner ring of the bearing 410 is abutted, thereby achieving the tightening of the bearing 410. The driven gear, the limiter 430 and the base frame 100 together form a second accommodating cavity suitable for accommodating the bearing 410, ensuring that the bearing 410 is in the proper position and providing sufficient space to accommodate the bearing 410 so that it can operate normally. Under the action of the bolts, the driven gear and the limiter 430 have a tendency to move closer to each other. While the bolts are tightened, the headlight module 200 presses the inner ring of the bearing 410 tightly against the step surface of the driven gear, thereby achieving the tightening of the bearing 410. This design simplifies the assembly process while ensuring the stability and reliability of the bearing 410.

[0057] An embodiment of the utility model further provides a motorcycle, comprising the above-mentioned follow-up light assembly, and also comprising a sensing module and a control module;

[0058] The perception module is used to perceive the current body posture of the vehicle, and the control module is used to control the follow-up light group to deflect to adapt to the current body posture according to the feedback of the perception module.

[0059] The perception module usually obtains information such as the vehicle's tilt angle and steering angle through built-in sensors (such as gyroscopes, accelerometers, etc.). This information can help the motorcycle system understand the current driving status of the vehicle, including straight driving, turning, tilting, etc. The control module takes corresponding measures to control the deflection of the follow-up light group based on the feedback information provided by the perception module to ensure that the lighting area and light path remain unchanged, which helps to improve visibility and safety during night driving, reduce lighting dead angles or visual blind spots caused by the tilt of the vehicle body, and reduce the risk of accidents.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
