Description

Technical Field

[0001] This utility model relates to the field of motorcycle lamp technology, and in particular to a motorcycle lamp with a buffer structure. Background Technology

[0002] Motorcycles, as flexible and convenient means of transportation, are widely used in daily commutes and outdoor travel. Their lighting systems are key components for ensuring driving safety. However, the existing structure of motorcycle lights typically involves a fixed connection between the lamp cover and the lamp housing, lacking effective cushioning and shock absorption design. When subjected to vibration or external impact, the rigidly connected lamp cover is prone to directly bearing the impact force, leading to lamp cover breakage, lamp housing deformation, and even damage to internal light-emitting elements. This not only affects the normal use of the lights and increases maintenance costs, but may also cause traffic safety hazards due to light failure. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a motorcycle lamp with a buffer structure.

[0004] The above objective is achieved through the following technical solution:

[0005] A motorcycle lamp with a buffer structure includes a rear lamp housing and a front lamp cover assembly. A mounting part is provided on the outer front end of the rear lamp housing. The front lamp cover assembly includes a circular fixing piece, a movable ring seat, and a lamp cover. The circular fixing piece is fixedly disposed on the front end of the mounting part, and a movable space is formed between the circular fixing piece and the mounting part. The movable ring seat moves back and forth within the movable space, and an elastic element is connected between the rear side of the movable ring seat and the mounting part. The lamp cover is disposed on the movable ring seat.

[0006] In some embodiments, the mounting portion includes a bottom ring disposed on the outer edge of the front end of the rear lamp housing, the outer edge of the bottom ring being provided with a forward-extending fixing ring, and the circular fixing piece being disposed within the fixing ring.

[0007] In some embodiments, the device further includes a plurality of screws for fixing the annular fixing piece. A plurality of screw posts are evenly distributed along the circumference on the rear end wall of the annular fixing piece. The rear end of the screw post abuts against the bottom ring and is threadedly connected to the screw post by passing through the rear end of the bottom ring.

[0008] In some embodiments, four screw posts are evenly distributed along the circumference.

[0009] In some embodiments, the movable ring seat includes a movable ring plate and a movable retaining ring disposed inside the movable ring plate. The movable ring plate is provided with a plurality of through holes corresponding to the screw post. The screw post passes through the through holes. The lampshade is fixedly disposed at the front end of the movable retaining ring. The circular fixing piece is disposed between the fixed retaining ring and the movable retaining ring.

[0010] In some embodiments, the elastic element is a spring, and a spring is sleeved on each of the screw posts, with one end of the spring abutting against the bottom ring and the other end abutting against the movable ring plate.

[0011] In some embodiments, an outer sealing ring is provided on the outer side of the annular fixing piece, and the outer sealing ring abuts against the fixing retaining ring.

[0012] In some embodiments, an inner sealing ring is provided on the inner side of the annular fixing piece, and the inner sealing ring abuts against the movable retaining ring.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: By setting an elastic element between the rear lamp housing mounting part and the movable ring seat, and reserving a space for movement, the movable ring seat can drive the lamp cover to move back and forth. When the lamp is subjected to external forces such as collisions, the elastic element can quickly absorb the impact force and buffer the effect of external forces on the lamp cover and internal components through its own deformation, avoiding lamp cover breakage, lamp housing deformation or damage to internal light-emitting elements, significantly improving the impact resistance and durability of motorcycle lamps, and extending the overall service life of the lamp.

[0019] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0020] like Figures 1-5 As shown, this embodiment provides a motorcycle lamp with a buffer structure, including a rear lamp housing 1 and a front lamp cover assembly 2. A mounting part is provided on the outer side of the front end of the rear lamp housing 1. The front lamp cover assembly 2 includes a circular fixing piece 3, a movable ring seat 4, and a lamp cover 5. The circular fixing piece 3 is fixedly disposed on the front end of the mounting part, and a movable space 6 is formed between the circular fixing piece 3 and the mounting part. The movable ring seat 4 moves back and forth within the movable space 6, and an elastic element is connected between the rear side of the movable ring seat 4 and the mounting part. The lamp cover 5 is disposed on the movable ring seat 4.

[0021] Specifically, the mounting portion on the outer front end of the rear lamp housing 1 provides fixed support for the entire buffer structure. After the circular fixing piece 3 is fixed to the front end of the mounting portion, it together with the mounting portion forms a closed movable space 6. This space provides a precise travel range for the forward and backward movement of the movable ring seat 4, preventing the movable ring seat 4 from shifting or falling off. When the lamp cover 5 is subjected to external forces such as frontal collision or compression, the external force will be directly transmitted to the movable ring seat 4, which is fixedly connected to the lamp cover 5. Since the movable ring seat 4 can move freely forward and backward within the movable space 6, and there is an elastic element connected between its rear side and the mounting portion, the movable ring seat 4 will compress the elastic element along the direction of the external force. The elastic element absorbs the external force energy through its own deformation, converting the instantaneous impact force into elastic potential energy, thereby achieving buffering and dissipation of the external force. When the external force disappears, the compressed elastic element will release its elastic potential energy, generating a reverse thrust, pushing the movable ring seat 4 forward along the movable space 6 to reset to its initial position, causing the lamp cover 5 to return to its original shape, ensuring that the appearance structure of the lamp is intact and that the lighting and warning functions are not affected. Throughout the process, the circular fixing piece 3 always plays a limiting role, preventing the movable ring seat 4 from dislodging from the movable space 6 due to excessive restoring force of the elastic element, thus ensuring the stable operation of the buffer structure.

[0022] See Figures 2-5 As shown, the mounting part includes a bottom ring 21 located on the outer edge of the front end of the rear lamp housing 1. A forward-extending fixing ring 22 is provided on the outer edge of the bottom ring 21, and the circular fixing piece 3 is located inside the fixing ring 22.

[0023] Thus, the bottom ring 21 on the outer edge of the front end of the rear lamp housing 1 provides a basic bearing surface for the entire mounting part, and the fixed retaining ring 22 extending forward from its outer edge forms an annular mounting groove structure; when the circular fixing piece 3 is assembled in the fixed retaining ring 22, the inner side wall of the fixed retaining ring 22 plays a radial limiting role on the circular fixing piece 3, ensuring that the circular fixing piece 3 is accurately aligned and installed, avoiding misalignment during assembly, and at the same time, it cooperates with the bottom ring 21 to form a closed and precisely sized movable space 6, providing a stable track for the front and rear movement of the movable ring seat 4.

[0024] It also includes a number of screws 31 for fixing the annular fixing piece 3. A number of screw posts 32 are evenly distributed around the rear end wall of the annular fixing piece 3. The rear end of the screw post 32 abuts against the bottom ring 21 and is threadedly connected to the screw post 32 through the rear end of the bottom ring 21 by the screw 31. There are four screw posts 32 evenly distributed around the circumference.

[0025] Thus, the four screw posts 32, which are evenly distributed around the circumference of the rear end wall of the annular fixing piece 3, precisely abut against the front end face of the bottom ring 21 during assembly, forming a four-point support structure; the screws 31 pass through the rear end of the bottom ring 21 and are threadedly connected to the screw posts 32, and the preload generated by the thread engagement securely locks the annular fixing piece 3 in the fixing retaining ring 22; the design of the four screw posts being evenly distributed around the circumference ensures that the fixing force is evenly distributed in the circumferential direction of the annular fixing piece 3, avoiding installation offset caused by local force concentration.

[0026] See Figures 3-5 As shown, the movable ring seat 4 includes a movable ring plate 51 and a movable retaining ring 52 disposed inside the movable ring plate 51. The movable ring plate 51 is provided with a plurality of through holes 53 corresponding to the screw post 32. The screw post 32 passes through the through holes 53. The lamp cover 5 is fixedly disposed at the front end of the movable retaining ring 52. The circular fixing piece 3 is disposed between the fixed retaining ring 22 and the movable retaining ring 52.

[0027] Furthermore, the elastic element is a spring 61, and a spring 61 is sleeved on each of the screw posts 32. One end of the spring 61 abuts against the bottom ring 21, and the other end abuts against the movable ring plate 51.

[0028] Thus, the movable ring seat 4 is composed of a movable ring plate 51 and an inner integrally formed movable retaining ring 52. The lampshade 5 is fixed to the front end of the movable retaining ring 52. The through holes 53 on the movable ring plate 51 correspond one-to-one with the four screw posts 32. During assembly, the screw posts 32 pass through the through holes 53, and at the same time, the circular fixing plate 3 is located between the fixed retaining ring 22 and the movable retaining ring 52, forming a radial limit. The spring 61 is sleeved on the outside of each screw post 32, with one end abutting against the bottom ring 21 and the other end abutting against the movable ring plate 51, so that the movable ring seat 4 is in a pre-supported state within the movable space 6. The cooperation between the screw posts 32 and the through holes 53 forms an axial guiding structure, restricting the movable ring seat 4 to move only along the axial direction (front and back direction) of the screw posts 32, and preventing displacement.

[0029] When the lampshade 5 is impacted or squeezed from the front, the external force is transmitted to the movable ring plate 51 through the movable retaining ring 52. The movable ring plate 51 moves backward along the guide direction of the screw post 32, simultaneously compressing the four springs 61 sleeved on the screw post 32. Since the four springs are evenly distributed and each corresponds to an independent screw post, the external force is evenly distributed to each spring. The springs quickly absorb energy through elastic deformation, converting the instantaneous impact force into elastic potential energy, thus achieving buffer protection for the lampshade and internal components. At the same time, the sliding fit between the screw post 32 and the through hole 53 ensures that the backward travel of the movable ring seat 4 is precisely controllable, avoiding movement jamming or deviation.

[0030] When the external force disappears, the four evenly distributed springs 61 simultaneously release their elastic potential energy, generating a uniform reverse thrust that acts on the movable ring plate 51, pushing the movable ring seat 4 forward along the guide direction of the screw post 32 to reset. At this time, the relative position of the movable retaining ring 52 and the circular fixing plate 3 forms a travel limit, ensuring that the movable ring seat 4 stops after resetting to its initial position, avoiding excessive reset that could cause the lampshade to shift.

[0031] See Figure 5 As shown, an outer sealing ring 71 is provided on the outer side of the circular fixing piece 3, and the outer sealing ring 71 abuts against the fixed retaining ring 22. An inner sealing ring 81 is provided on the inner side of the circular fixing piece 3, and the inner sealing ring 81 abuts against the movable retaining ring 52.

[0032] Thus, the outer sealing ring 71 and the inner sealing ring 81 form a double protective structure of outer blocking and inner sealing, which respectively seals the gaps at the fixed connection and the dynamic sliding part, blocking rainwater, dust, mud and other impurities from entering in all directions. This completely solves the problem of weak sealing caused by the existence of movement gaps in traditional buffer structures, and greatly improves the waterproof and dustproof performance of the lamp.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
