DETAILED DESCRIPTION

[0023] The embodiment of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] As Figures 1-5 shown, in the embodiment, a headlamp support structure for motorcycle includes a clamp 1, the clamp 1 is fixedly installed with the motorcycle front fork, a connecting plate 2 is fixed between the two clamps 1 to strengthen the connection stability between the two clamps 1 and make the two clamps 1 keep the same height, the clamp 1 is respectively fixed with a front extending headlamp support 3 outside, a headlamp 4 is installed between the two headlamp supports 3 to make the headlamp 4 located at the front side of the motorcycle front fork, the headlamp support 3 includes a fixed plate 31, an expansion plate 32 and a shock absorber 33, one end of the fixed plate 31 is fixed radially with the clamp 1, the other end is slidably connected with the expansion plate 32, the outer end of the expansion plate 32 is installed with the headlamp 4, the shock absorber 33 is installed between the fixed plate 31 and the expansion plate 32 to reduce the horizontal impact force generated by the headlamp 4 due to external collision, and the expansion of the fixed plate 31 and the expansion plate 32 is matched to protect the headlamp 4 from being damaged.

[0026] The inner side of the two fixed plates 31 is provided with a sliding groove 311, the telescopic plate 32 is horizontally slidably connected along the sliding groove 311, the fixed plate 31 is provided with a shock absorber connecting seat A 312, the telescopic plate 32 is provided with a shock absorber connecting seat B 321, the two ends of the shock absorber 33 are bolted with the shock absorber connecting seat A 312 and the shock absorber connecting seat B 321 respectively, the outer end of the two telescopic plates 32 is provided with a headlight connecting head 322, and the headlight connecting head 322 is bolted with the headlight 4.

[0027] The fixed plate 31 is provided with two coaxial circular holes 313, the shock absorber connecting seat A 312 is installed in the circular hole 313 close to the headlight 4, and the resistance groove 314 is connected between the two circular holes 313, the width of the resistance groove 314 is smaller than the diameter of the circular hole 313, so that the shock absorber connecting seat A 312 has resistance when moving horizontally, and the resistance of the shock absorber connecting seat A 312 moving in the resistance groove 314 is greater than the maximum load value of the shock absorber 33, so that the shock absorber 33 can be normally used when subjected to smaller thrust, and when subjected to greater impact force, under extreme impact force, the slotted cone 3124 slides along the resistance groove 314 to make the resistance groove 314 plastically deformed, so that the shock absorber connecting seat A 312 passively slips, at this time, the material on both sides of the resistance groove 314 produces irreversible expansion deformation, the fixed plate 31 needs to be replaced to realize the function reset, and the shock absorber 33 is protected from being easily damaged, and the fixed plate 31 with damaged resistance groove 314 has low replacement cost.

[0028] Specifically, the first stage buffer of the shock absorber 33 absorbs regular vibration impact through its own elastic deformation; when the impact force exceeds the rated load of the shock absorber 33, the slotted cone 3124 of the resistance groove 314 and the compression friction of the groove wall form the second stage buffer, and the local structural integrity of the fixed plate 31 is sacrificed to avoid the fracture of the shock absorber 33 due to overload.

[0029] Specifically, the fixed plate 31 is made of 6061-T6 aluminum alloy material, which is treated by aging strengthening to ensure that the resistance groove 314 can withstand an impact load of ≥500N before plastic deformation; the slotted cone 3124 is made of high-carbon steel surface carburizing hardening, with a hardness of HRC55-60, to ensure that the fixed plate 31 is preferentially worn when rubbing with the resistance groove 314.

[0030] The shock absorber connecting seat A312 comprises a cylinder 3121, a baffle 3122 and a shock absorber connecting column 3123, the cylinder 3121 is located in the round hole 313, the baffle 3122 is fixed at both ends of the cylinder 3121, the two baffles 3122 are located on both sides of the fixed plate 31 respectively, the diameter of the baffle 3122 is larger than the hole diameter of the round hole 313, the axial displacement of the cylinder 3121 is limited, the shock absorber 33 is ensured to transmit the impact force only in the horizontal direction, the shock absorber connecting column 3123 is fixed at the axis of the inner baffle 3122, and the shock absorber connecting column 3123 is mounted with the shock absorber 33 through bolts.

[0031] The outer side of the cylinder 3121 is fixed with a slotted cone 3124 with a triangular cross section, the slotted cone 3124 is located in the resistance groove 314, the two sides of the slotted cone 3124 are tangent to the surface of the cylinder 3121, so that the cylinder 3121 is more easily expanded when moving in the resistance groove 314, and the risk of breakage of the cylinder 3121 is reduced.

[0032] The headlamp connecting head 322 is provided with a headlamp angle supporting device 323, so that the headlamp 4 is more easily fixed in angle when the angle is adjusted.

[0033] The headlamp angle supporting device 323 comprises a fixed ring 3231, a semicircular groove 3232, a spring pin 3233 and a spherical head 3234, the fixed ring 3231 is arranged at the bolt mounting position of the headlamp 4, the semicircular groove 3232 is formed in the circumference of the fixed ring 3231, the spring pin 3233 is bolted to the outer side of the headlamp connecting head 322, the spherical head 3234 is arranged at the tail end of the spring pin 3233, and the spherical head 3234 is buckled with the semicircular groove 3232. When the headlamp 4 is rotated to adjust the irradiation angle, in addition to the friction force of the bolt connection between the headlamp 4 and the headlamp connecting head 322 for fixing the angle, the spherical head 3234 of the spring pin 3233 can also be buckled with different groove positions, the resistance of the headlamp 4 during rotation adjustment is increased, multi-gear fine adjustment of the irradiation angle of the headlamp 4 is realized, the headlamp 4 is more stable after angle adjustment, and the phenomenon that the angle of the headlamp 4 is changed due to bumping is avoided.

[0034] The clamp 1 comprises a fixed sheet 11, a rotating sheet 12 and a support plate 13, the fixed sheet 11 is fixed with the connecting plate 2, the rotating sheet 12 is hinged with the connecting plate 2, the support plate 13 is fixed outside the fixed sheet 11, the support plate 13 is bolted with the fixed plate 31, the fixed sheet 11 and the rotating sheet 12 are both semicircular sheet structures and can form a complete ring, and the clamp 1 is bolted and mounted with the front fork of the motorcycle. The clamp 1 is more convenient to disassemble and assemble. When the clamp 1 is mounted, the fixed sheet 11 and the rotating sheet 12 are overlapped and locked by stainless steel bolts, a torque of 25-30 N·m is applied to ensure the pre-tightening force of the clamp on the front fork of the motorcycle, and loosening due to riding vibration is avoided.

[0035] The working principle of the utility model is:

[0036] First level buffer: When the motorcycle encounters regular vibration or minor impact, the horizontal impact force is transmitted to the telescopic plate 32 through the headlamp 4, driving the telescopic plate 32 to slide along the sliding groove 311 of the fixed plate 31, at this time the shock absorber 33 absorbs energy through its elastic deformation, converts the impact force into heat energy dissipation, avoids displacement or loosening of the headlamp 4 due to direct force.

[0037] Second level buffer: If the impact force exceeds the rated load of the shock absorber 33, compression friction occurs between the slotted cone 3124 of the shock absorber connecting seat A312 and the resistance groove 314. Because the width of the resistance groove 314 is smaller than the diameter of the round hole 313, and the triangular cross-section design of the slotted cone 3124, the impact force forces the slotted cone 3124 to plastically expand and deform the side wall of the resistance groove 314, forming passive sliding. This process transfers the overload impact energy to the irreversible deformation of the fixed plate 31, thereby protecting the shock absorber 33 from breaking. The fixed plate 31 as an independent module can be replaced individually after damage, significantly reducing maintenance costs.

[0038] Multi-position adjustment: When rotating the headlamp 4, the semicircular groove 3232 on the fixed ring 3231 is elastically buckled with the spherical head 3234 at the end of the spring pin 3233, and through the spherical head 3234 and the clamping of different groove positions, the multi-position fine adjustment of the illumination angle is realized. After adjustment is completed, the bolted headlamp connecting head 322 provides basic friction force, and the pre-tightening force of the spring pin 3233 further increases the rotation resistance through the buckling of the spherical head 3234 and the semicircular groove 3232, Double action ensures that the headlamp 4 is stable in angle in the bumpy environment, avoiding vibration offset.

[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
