Description

Technical Field

[0001] This utility model relates to the field of motorcycle headlight technology, specifically a headlight lens assembly that can be dimmed as a whole. Background Technology

[0002] In the motorcycle industry, the configuration of headlights is crucial for the rider's visibility and safety. Headlights typically include high beams and low beams. High beams provide highly concentrated light and greater brightness, suitable for suburban or high-speed driving to expand the field of vision. In contrast, low beams illuminate a wider area ahead with diffused light, suitable for urban driving to avoid glare for oncoming vehicles and impair visibility. Therefore, the proper configuration of high and low beams is essential for improving the safety and comfort of motorcycle riding.

[0003] Currently, motorcycle headlights mainly come in two forms: separate high and low beam headlights and integrated high and low beam headlights. Separate high and low beam headlights are equipped with independent high and low beams, which can be switched independently as needed; while integrated high and low beam headlights integrate the high and low beam functions into a single headlight unit, achieving high and low beam switching through an internal mechanism. The former, because it requires two independent light sources, is usually larger, increasing both the load on the front structure and manufacturing costs; the latter has limitations in lateral space utilization and occupies a larger lateral space. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a headlight lens assembly with overall dimming capability, which solves the problem that existing integrated high and low beam headlights are large in size and occupy a lot of horizontal space.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A headlight lens assembly with overall dimming capability includes: a heat dissipation base comprising a finned housing with two mounting slots for mounting a lamp plate; a lens assembly mounted in the slots, comprising a lens bracket and a lens body fitted into the lens bracket; a dimming bracket connecting the housing and the lens assembly via a baffle, such that the three are arranged compactly along the same axis; a dimming port is provided in the middle of the baffle, with the lamp plate and the lens body corresponding to the two sides of the dimming port and coaxially aligned; a light shield is rotatably mounted inside the dimming port, and a solenoid valve for driving the light shield to rotate is provided on one side of the baffle.

[0007] According to one embodiment of the present invention, the fins of the housing are integrally formed with the housing, the lamp plate is disposed close to the inner side wall of the housing, the solenoid valve is installed on the side of the baffle near the housing, and the housing is provided with a clearance groove to accommodate the installation of the solenoid valve.

[0008] According to one embodiment of the present invention, the baffle is provided with two fixing plates, which are located below the dimming port and are connected to the light shield via a rotating shaft; in the low beam state, the light shield on the light shield is located between the lamp plate and the lens body; when switching to the high beam state, the light shield is flipped to avoid the light path between the lamp plate and the lens body by a solenoid valve.

[0009] According to one embodiment of the present invention, the light shield is provided with a rotating plate, and the output end of the solenoid valve is connected to the rotating plate on one side of the light shield through a connector. The outline of the light shield is adapted to the shape of the dimming port.

[0010] According to one embodiment of the present invention, the connector head is provided with an annular slot, the rotating plate is a T-shaped structure, its two symmetrical ends are hinged to the light shield, and one end is provided with a plug notch adapted to the annular slot.

[0011] According to one embodiment of the present invention, a reset spring is sleeved on the output end of the solenoid valve, and the reset spring is located between the solenoid valve body and the rotating plate.

[0012] According to one embodiment of the present invention, the central hole of the lens holder is interference-fitted with the lens body, and the end face of the lens holder is fitted and connected to the baffle to shorten the axial distance.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. High and low beam switching is achieved by using a single lamp panel with a movable light shield, eliminating the need for two independent light sources. The light shield is driven by a solenoid valve, resulting in a simple and reliable structure that reduces the number of parts, manufacturing costs, and assembly complexity, while ensuring consistent optical performance.

[0015] 2. The heat dissipation base, dimming bracket and lens assembly are arranged compactly along the same axis, and the lamp plate, light shield and lens are aligned coaxially by the baffle structure to form an axially compact layout that effectively reduces the lateral space occupation and improves the space utilization efficiency of the overall structure. It is suitable for installation environments with limited space at the front of motorcycles. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 As shown, this utility model discloses a headlight lens assembly that can be dimmed as a whole, which aims to provide a headlight component with a compact structure, fast dimming response, good heat dissipation performance and reliable high and low beam switching.

[0025] Reference Figure 2 As shown, the headlight lens assembly with overall dimming includes a heat dissipation base 1, a dimming bracket 2, and a lens assembly 3. The compact arrangement of the heat dissipation base 1, the dimming bracket 2, and the lens assembly 3 along the same axis ensures optical performance, while the compact arrangement of the three also takes into account heat dissipation and structural stability.

[0026] like Figure 3As shown, the heat dissipation base 1 is the basic support and main heat dissipation component of the entire assembly. The heat dissipation base 1 includes a shell 101 with fins. The fins are integrally formed with the shell 101, which allows the heat dissipation base 1 to maximize the heat dissipation area and effectively improve the heat dissipation efficiency. The shell 101 is provided with two mounting slots for mounting the lamp plate 102. The lamp plate 102 serves as a light source and is set close to the inner side wall of the shell 101. This allows the heat generated by the lamp plate 102 during operation to be quickly conducted to the shell 101 and dissipated into the air through the external fins.

[0027] like Figure 6 As shown, the lens assembly 3 is installed at the slot of the mounting groove of the housing 101 and is used to refract and distribute the light emitted by the lamp panel 102. The lens assembly 3 includes a lens bracket 301 and a lens body 302. The lens body 302 is embedded in the central hole of the lens bracket 301. The two are preferably fitted with an interference fit to ensure the stability of the connection and the alignment accuracy of the optical center. The end face of the lens bracket 301 is fastened to the baffle 201. This helps to shorten the axial distance of the entire assembly and achieve a compact layout.

[0028] like Figure 4 As shown, the dimming bracket 2 is the core component for switching between high and low beams. It connects the housing 101 and the lens assembly 3 via a baffle 201, thereby arranging the heat dissipation base 1, the dimming bracket 2, and the lens assembly 3 compactly along the same axis. A dimming port 2011 is provided in the middle of the baffle 201. The lamp plate 102 and the lens body 302 correspond to the two sides of the dimming port 2011, and the three are coaxially aligned to ensure that the light can accurately pass through the dimming port 2011 and be emitted through the lens body 302. A light shield 202 is rotatably installed inside the dimming port 2011. The outline of the light shield 202 is adapted to the shape of the dimming port 2011 to minimize interference with the light path when not blocking the light, and to form an effective shield when light needs to be blocked. A solenoid valve 203 is provided on one side of the baffle 201 to drive the rotation of the light shield 202.

[0029] Specifically, the baffle 201 is provided with two fixing plates 2012, which are located below the dimming port 2011. The fixing plates 2012 are connected to the light shield 202 through the rotating shaft 2021, so that the light shield 202 can rotate around the rotating shaft 2021. In the low beam state, the light shield on the light shield 202 is the arc-shaped part of the light shield 202, which is located between the lamp plate 102 and the lens body 302, and is used to block part of the light to form a low beam pattern. When it is necessary to switch to the high beam state, the light shield 202 is driven to rotate by the solenoid valve 203, and the light shield is flipped to avoid the light path between the lamp plate 102 and the lens body 302. At this time, all the light can be emitted to form a high beam pattern.

[0030] To achieve effective actuation of the solenoid valve 203 to the light shield 202, a rotating plate 204 is provided on the light shield 202. The output end of the solenoid valve 203 is connected to the rotating plate 204 on one side of the light shield 202 via a connector 2031. Further, as... Figure 5 As shown, the connector 2031 has an annular slot 2032, and the rotating plate 204 is designed as a T-shaped structure. Its two symmetrical ends are hinged to the light shield 202, and the other end has a plug notch 2041 that is adapted to the annular slot 2032. Through the cooperation between the plug notch 2041 and the annular slot 2032, the output end of the solenoid valve 203 is movably connected to the rotating plate 204, so that the linear motion of the solenoid valve 203 can be effectively converted into the rotational motion of the light shield 202.

[0031] A reset spring 205 is also fitted on the output end of the solenoid valve 203. The reset spring 205 is located between the solenoid valve 203 body and the rotating plate 204. When the solenoid valve 203 is de-energized, the elastic force of the reset spring 205 can push the rotating plate 204 to reset in the opposite direction, thereby driving the light shield 202 to rotate to the low beam working position where the light shield cuts into the light path. That is, when the solenoid valve 203 is not activated, the lamp plate 102 is in low beam mode when energized, which is in line with conventional usage habits.

[0032] In low beam mode, the light shield on the light shield 202 is located between the lamp plate 102 and the lens body 302, and the cutting angle of the light shield is at a preset angle with the light-emitting surface of the lamp plate 102. This preset angle is a prior art method that can form a light and dark cutoff line on the road surface that meets the requirements of regulations, so as to avoid glare for drivers of oncoming vehicles.

[0033] To ensure the smooth installation of the solenoid valve 203 and the compactness of the overall structure, the solenoid valve 203 is installed on the side of the baffle 201 close to the housing 101, and the housing 101 is provided with a clearance groove 1011 corresponding to the installation position of the solenoid valve 203.

[0034] To ensure the axial positioning accuracy of the dimming bracket 2 and the heat dissipation base 1, the contact surface between the baffle 201 and the housing 101 is provided with a positioning groove. The positioning groove is embedded in the limiting protrusion on the side wall of the clearance groove 1011 on the housing 101. The dimming bracket 2 and the housing 101 achieve precise axial positioning through the interlocking of the positioning groove and the limiting protrusion. The limiting protrusion is also provided with bolt holes. The lens bracket 301 and the housing 101 are fixedly connected by bolts and bolt holes.

[0035] The working process of this utility model is as follows:

[0036] Low beam mode: When the solenoid valve 203 is not energized, under the action of the reset spring 205, the light shield on the light shield 202 is kept in the light path between the lamp plate 102 and the lens body 302, blocking part of the light and forming a low beam pattern with a light and dark cutoff line.

[0037] High beam mode: When it is necessary to switch to high beam, the solenoid valve 203 is energized, and its output end extends out. Through the connector 2031, it drives the rotating plate 204. The rotating plate 204 drives the light shield 202 to rotate around the rotating shaft 2021, flipping the light shield to avoid the light path between the lamp panel 102 and the lens body 302. At this time, all the light emitted by the lamp panel 102 passes through the dimming port 2011 and is emitted through the lens body 302 to form the high beam pattern.

[0038] When it is necessary to switch from high beam back to low beam, the solenoid valve 203 is de-energized, and its output end retracts under the action of the reset spring 205. The reset spring 205 pushes the rotating plate 204 to move in the opposite direction, causing the sunshade 202 to rotate, and the sunshade re-enters the optical path, restoring the low beam state.

[0039] The headlight lens assembly with overall dimming provided by this utility model integrates heat dissipation, optics and dimming functions into one through ingenious structural design. It has a compact structure, fast and reliable dimming response, excellent heat dissipation performance and high installation positioning accuracy. It can effectively realize the switching between high and low beams and meet the usage requirements of vehicle headlights.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
