[0030] The features and other related features of the present application are further described in detail by the following examples, so as to facilitate the understanding of the technical personnel in the same industry:

[0031] As Figures 1 to 5The embodiment is a vehicle lamp facilitating height adjustment of light, comprising a lamp shell 1, a lampshade 2, a lighting fixture assembly 3, a vehicle lamp height adjustment assembly, and an adjustment button 5. The lampshade 2 is arranged on the front side of the lamp shell 1 to prevent dust and water and diffuse light, and the lighting fixture assembly 3 is installed inside the lampshade 2. The lamp shell 1 is located on the rear side and serves as a mounting carrier of the overall structure, is made of transparent material, and is clamped with the front side edge of the lamp shell 1 to form a sealed lighting cavity. The vehicle lamp height adjustment assembly is installed on the lamp shell 1 and is the core structure for realizing height adjustment of light. The vehicle lamp height adjustment assembly comprises:

[0032] A horizontal vertical plate 41 is hingedly connected to the two sides of the lamp shell 1 at both ends of the upper edge thereof, so as to be able to swing forward and upward and swing backward and downward around the hinge points. The lighting fixture assembly 3 is installed on the horizontal vertical plate 41.

[0033] A push-pull rod motor 42 is connected to the horizontal vertical plate 41 at a position close to the lower edge thereof, and is used to push the horizontal vertical plate 41 to swing forward and upward around the horizontal hinge shaft and pull the horizontal vertical plate 41 to swing backward and downward, so as to realize height adjustment of light of the lighting fixture assembly 3. The horizontal hinge shaft refers to a rotating shaft with an axis extending along the width direction of the lamp shell 1, and both ends of the rotating shaft are fixed to the inner walls of the two sides of the lamp shell 1. The axis is parallel to the ground, and provides a fixed rotation center for the upward and downward swinging of the horizontal vertical plate 41, so as to ensure that the swinging track always surrounds the axis, and thus accurately adjust the height angle of light.

[0034] As described above, the lamp shell, the lampshade, the lighting fixture assembly, the horizontal vertical plate, and the push-pull rod motor are combined to provide a rotating center for the horizontal hinge shaft, so that the horizontal vertical plate drives the lighting fixture assembly to swing upward and downward around the axis, directly realizes height adjustment of light, does not need additional intermediate transmission components, has a simple and compact structure, greatly reduces the volume compared with a traditional gear transmission structure, and is perfectly adapted to vehicle models with limited installation space such as tricycles and electric vehicles. On the other hand, the push-pull rod motor is directly connected to the lower edge of the horizontal vertical plate, power transmission is lossless, and adjustment response is rapid. The horizontal vertical plate is a large support plate body extending horizontally and matching the length of the lamp shell, so that the installation carrier of the lighting fixture assembly has high rigidity and small deformation, and reduces the shaking of the lighting fixture assembly when the plate swings. The push-pull rod motor directly drives the plate, power transmission is direct and lossless, the swinging track of the plate is stable, and thus the lighting direction of the lamp is accurate. In this way, the vehicle lamp of the present application reduces shaking and ensures accurate lighting direction during light adjustment, solves the problems of traditional fixed-angle vehicle lamps, such as difficulty in adapting to complex road conditions, slow adjustment response, and poor stability, and through simple and direct structural design, efficiently adjusts the height of light, reduces structural complexity and assembly cost, and takes into account installation adaptability and use reliability.

[0035] In addition, the existing light adjustment device for small vehicles is mostly manually mechanical adjustment, which needs the driver to operate in the repair shop, and the adjustment process is complicated and cannot be flexibly adjusted according to the real-time road conditions during driving. Therefore, as shown in Figure 1 As a preferred embodiment, the vehicle lamp also includes:

[0036] The adjustment button 5 is connected to the control system of the vehicle lamp through the wire harness, and realizes electrical control connection with the height adjustment assembly of the vehicle lamp. The button can be installed at a position within the reach of the driver, such as near the handlebar, instrument panel or rearview mirror. At the same time, the adjustment button 5 is provided with an up button 51 and a down button 52. The up button 51 is used to control the height adjustment assembly of the vehicle lamp to push the horizontal vertical plate to raise the illumination angle, and the down button 52 is used to control the height adjustment assembly of the vehicle lamp to pull the horizontal vertical plate to lower the illumination angle, so as to realize the height adjustment of the light. In specific implementation, it can be fixed by adhesive or buckle at a position that is easy to touch, such as handlebar, rearview mirror support, etc., without the need to make substantial modification to the vehicle, and is suitable for the structural characteristics of different vehicle models, and has strong universality. In this way, by adding the adjustment button with the up button and the down button, the adjustment button 5 is driven and matched with the push-pull rod motor 42, so as to realize convenient operation during driving, without the need to go to the corresponding store for maintenance operation, and to adapt to the real-time adjustment requirement of complex road conditions, without affecting the driving safety, and with high adjustment convenience.

[0037] As shown in Figures 2-4 As a preferred embodiment, the hinge structure includes a clamping block 61, a clamping cylinder 62 and a clamping groove 63. The clamping block 61 is formed by protruding outward from the left and right sides of the upper edge of the horizontal vertical plate 41, the clamping groove 63 is provided at the corresponding position on the left and right sides of the lamp shell 1, the clamping cylinder 62 is shaped to fit and limit the clamping groove 63, the clamping block 61 is clamped into the clamping cylinder 62 and tightly fits the inner wall of the clamping cylinder 62, and the corners of the clamping block 61 are rounded to reduce the friction resistance during rotation and ensure smooth swinging. If the clamping cylinder is not stable enough after being clamped into the clamping groove of the lamp shell, it can be fixed by screws or the like. Specifically, the central axis of the clamping cylinder 62 is the horizontal hinge shaft mentioned above, which extends horizontally along the left and right directions of the lamp shell 1, and is fixed at the inner walls of the lamp shell 1 at both ends through the clamping groove 63, with the axis position flush with the upper edge of the horizontal vertical plate 41.

[0038] As described above, the present case is designed by the triple cooperation of the block, the cartridge and the slot. On the one hand, the corner of the block is rounded, which cooperates with the smooth inner wall of the cartridge to reduce the rotating friction resistance, so that the horizontal stand rotates smoothly without jamming, avoiding the blocking phenomenon during the adjustment process. On the other hand, the cartridge is fixed after being inserted into the lamp shell slot, and the block is inserted into the cartridge to form a stable cooperation, which ensures that the hinged structure does not loosen and deviate during the bumpy driving of the vehicle, providing a stable rotating basis for the swing of the horizontal stand. The installation of the card joint type does not require complex tools and can be quickly completed, improving production efficiency and solving the problems of easy loosening, rotating jamming and complex assembly of traditional hinged structures. Through simple and stable structure design, the rotating smoothness of the hinged structure is ensured, the stability of the overall structure is enhanced, and the assembly cost and the difficulty of later maintenance are reduced.

[0039] As Figure 2 and Figure 3 shown, as a specific embodiment, the lighting fixture assembly 3 is at least one group; as preferred, it can be set as two groups, which are distributed symmetrically along the central axis of the horizontal stand 41, improving the uniformity of lighting; each group of lighting fixture assembly 3 includes a mounting shell 31 and a lighting bulb 32, the mounting shell 31 is fixed on the front side of the horizontal stand 41, and the lighting bulb 32 is installed inside the mounting shell 31; the left and right sides of the horizontal stand 41 are reserved with installation openings 411, and the front side is fixedly connected with mounting seats 412 above each installation opening 411, the mounting seats 412 are in the form of downward C-shaped structure, and each mounting seat 412 is connected with a mounting bottom plate 413 at the bottom; the left and right sides of the mounting bottom plate 413 are outwardly protruded to form two left and right symmetrical lap protrusions 414, which are lapped with a first connecting shell 33, and the first connecting shell 33 is fixedly connected with an arc-shaped second connecting shell 35 through a vertical connecting plate 34. Specifically, the first connecting shell 33 is provided with a lap portion 330 lapped on the lap protrusion 414 to realize the lapping of the first connecting shell 33 on the mounting bottom plate 413.

[0040] As described above, the lighting fixture assembly is installed on the swingable horizontal stand. The installation opening 411 preset on the horizontal stand reserves the installation space, and the mounting seat 412 above it serves as the installation basis, while the mounting bottom plate 413 fixed by lapping facilitates the subsequent installation of the connecting shell. The lap protrusions 414 on both sides of the mounting bottom plate are lapped with the first connecting shell 33, and the vertical connecting plate 34 is fixedly connected with the second connecting shell 35, which together form a rigid space frame extending forward from the horizontal stand, in the form of a semi-enclosed structure. On the one hand, this frame structure also reserves sufficient and orderly space for integrated heat sinks, circuit boards, buffer elements and other functional components, without interfering with the swing adjustment of the horizontal stand; on the other hand, the above components installed thereon effectively resist the vibration and inertial force generated during the driving of the vehicle and the adjustment of the light angle.

[0041] As shown in Figure 2 , as a specific embodiment, the transverse vertical plate 41 is provided with an elastic buffer structure corresponding to the mounting position of the lighting fixture assembly 3, which is stretched or compressed when the transverse vertical plate 41 swings; the elastic buffer structure is a spring 7, and the first connecting shell 33 extends at the top of the front side to form a first support part 331 below the mounting bottom plate 413, and the spring 7 is connected between the bottom surface of the mounting bottom plate 413 and the top surface of the first support part 331. In this way, the spring is arranged between the mounting bottom plate and the first support part as an elastic buffer structure, which can balance the gravitational force of the lamp in the pre-tightening state, so that the transverse vertical plate swings up and down uniformly, and the adjustment process is smoother, avoiding light shaking; on the other hand, when the transverse vertical plate swings, the spring is stretched or compressed in the swinging direction, which can absorb the impact force generated by swinging, reduce the vibration of the lamp assembly, avoid the damage of the lighting bulb due to frequent vibration, and solve the problems of lack of buffer in traditional adjustment structure, light shaking, and component damage due to impact. Through simple spring buffer design, the stability of light adjustment is improved, the service life of the lamp and the adjustment structure is prolonged, and the maintenance cost is reduced.

[0042] As shown in Figure 3 and Figure 4 , as a specific embodiment, the outer periphery of the second connecting shell 35 forms a support flange 351, and the PCB board 8 is placed on the support flange 351, and a plurality of silica gel pads 3510 are arranged on the surface of the support flange 351. In this way, the support flange provides a stable placement basis for the PCB board, which can limit the displacement of the PCB board in cooperation with the subsequent limiting support frame, ensuring that the PCB board does not loosen and deform when the vehicle bumps; on the other hand, the silica gel pads can protect the PCB board from wear and tear while absorbing the vibration generated by the vehicle during driving, further avoiding damage to electronic components on the PCB board due to vibration.

[0043] As shown in Figure 3 and Figure 4As shown, as a specific embodiment, the lateral upright plate 41 is connected with a lateral limiting support frame 9 near the lower edge position on the rear side, the limiting support frame 9 includes a lateral connecting part 91 fixed with the lateral upright plate 41, one or more oblique support parts 92 extending upward from the lateral connecting part 91, and a limiting blocking part 93 formed upward from the top end of at least one oblique support part 92, and the lateral upright plate 41, the support convex edge 351 and the plurality of limiting blocking parts 93 form a limiting space. In specific implementation, the plurality of oblique support parts 92 are preferably three left, middle and right, which can form multi-point support and further avoid deformation of the support frame after long-term use. In this way, on the one hand, the lateral connecting part is fixed with the lateral upright plate, the oblique support part enhances the overall rigidity of the support frame, and the limiting blocking part forms a limiting space with the lateral upright plate and the support convex edge, which is suitable for the size of the PCB board and ensures that the PCB board does not move forward and backward and left and right during vehicle driving and light adjustment; on the other hand, the limiting blocking part further blocks the PCB board to prevent displacement. The limiting support frame 9 of the case fully utilizes the installation space below the lateral upright plate, not only has a compact structure, but also solves the problems of lack of effective limiting, easy displacement and deformation, and insufficient protection of the traditional PCB board.

[0044] As shown in Figure 4 and Figure 5 As a specific embodiment, a heat sink 10 with a plurality of fins is installed above the PCB board 8; a heat dissipation mesh 11 is provided on the left side of the lamp shell 1, a first heat dissipation fan 12 is provided on the right side thereof, and a second heat dissipation fan 13 is installed on the rear side thereof. In this way, as described above, a forced convection heat dissipation structure is formed by the heat sink, the heat dissipation mesh and the double heat dissipation fans, on the one hand, the heat sink is located behind the illuminating bulb, which not only dissipates heat of the PCB board but also dissipates heat generated by the illuminating bulb; on the other hand, the first heat dissipation fan and the second heat dissipation fan blow air in the same direction to form an air flow channel through the inside of the lamp shell, and the heat is taken away by the heat sink and discharged from the heat dissipation mesh, effectively reducing the temperature inside the lamp shell.

[0045] As shown in Figure 3 and Figure 4 As a specific embodiment, the push-pull rod motor 42 is installed on the lamp shell 1 and the driving end thereof is connected to the lateral upright plate 41 through the rear side wall of the lamp shell 1, and the lateral upright plate 41 also protrudes to form a mounting convex edge 410 on one side of the lower edge thereof and is provided with a connecting hole on the mounting convex edge 410 for fixed connection of the driving end of the push-pull rod motor 42. In this way, the mounting convex edge provides a connection point for the driving end of the push-pull rod motor, which is stable in structure and accurate in positioning. The motor is fixed outside the lamp shell, which is convenient for later maintenance, maintenance and replacement without disassembling other parts inside the lamp shell.

[0046] As a specific embodiment, the adjusting button 5 is electrically connected with the PCB board 8 inside the lamp shell 1 through a wire, and the PCB board 8 and the push-pull rod motor 42 are also electrically connected through a wire. In this way, the electrical control connection is realized, and the PCB board is taken as the control core to receive and process the operation signal from the adjusting button, and then drive the push-pull rod motor to realize the angle adjustment.

[0047] The light adjustment process of the case is as follows:

[0048] When the driver needs to adjust the light angle, the up button of the adjusting button at the handlebar is pressed, an up low-level signal is output, transmitted to the PCB board through the connecting wire, and transmitted to the MCU module through the terminal; the internal preset control program of the MCU module recognizes the up signal and outputs an up control signal to the motor drive module; the motor drive module receives the control signal, amplifies it into a positive direct current that can drive the motor, and outputs it to the push-pull rod motor; the rotor of the push-pull rod motor rotates forward under the action of the positive current, the driving end is stretched out and pushes the horizontal stand plate, the horizontal stand plate swings forward and upward around the hinge shaft, the lighting lamp assembly installed on the horizontal stand plate is deflected upward synchronously, and the light irradiation angle is raised. During the upward swinging of the horizontal stand plate, the spring 7 between the mounting bottom plate and the first support part is slightly stretched to absorb the impact force in the swinging process. When the light angle needs to be adjusted, the down button of the adjusting button is pressed, and the principle is similar to the above. At this time, the spring gradually recovers from the stretched state to the natural state, and if the swinging angle is large, the spring can be slightly compressed to continue to play a buffering role.

[0049] In summary, the case is set through the lateral vertical plate, push-pull rod motor, hinged structure, on the one hand, with the lateral hinge shaft extending along the left and right direction of the lamp shell as the center of rotation, combined with the three-way cooperation of the clamping block, clamping cylinder and clamping groove, not only to ensure the smooth swing of the lateral vertical plate without jamming, but also to avoid deviation when the vehicle bumps through the stability of the hinged structure, to provide accurate and stable rotating basis for light height adjustment; on the other hand, the push-pull rod motor directly drives the lateral vertical plate to swing up and down around the hinge shaft, without complex gear transmission, not only reducing the overall structure size, adapting to the limited installation space of three-wheeled vehicles, electric vehicles and other vehicle models, but also reducing the intermediate transmission loss, adjusting response quickly and efficient power transmission. At the same time, the symmetrical lighting fixture assembly is connected with the lateral vertical plate through the elastic buffer spring, which can absorb the swing impact force and avoid light shaking and bulb damage; the PCB is fixed by the support convex edge and the limiting support frame, and the forced convection heat dissipation structure of the radiator and the double fan is matched, which effectively reduces the working temperature of electronic components and bulbs and prolongs the service life; the adjustment key can be flexibly installed at convenient positions such as handlebars and rearview mirrors, and the simple circuit connection structure is matched to realize blind operation during driving without stopping or significantly modifying the vehicle. In this way, without complex transmission and modification, through simple and compact structure design, the case not only realizes accurate, stable and convenient adjustment of light height, but also solves the problems of large size, high cost, complicated operation and poor stability of traditional adjustment structure, and takes into account the installation adaptability, use safety and post-maintenance convenience.

[0050] As described above, the case protects a vehicle lamp for convenient light height adjustment, and all technical solutions identical or similar to the case shall be considered to fall within the protection scope of the case.
