Description

Technical Field

[0001] This invention relates to the field of helmet technology, and in particular to a lens driving device. Background Technology

[0002] In road environments, helmet visors are the primary interface for riders to interact with the outside world. They serve multiple functions, including physical protection, airflow blocking, and optics, and directly determine a rider's perception of environmental information and safety at high speeds. These performance differences are highly dependent on the position and angle adjustment of the visor.

[0003] In related technologies, the position and angle adjustment of motorcycle helmet visors are rigid, and the visor travel is prone to deviating from the target position. Even if it is moved to the target position with difficulty, the deformation of the visor drive structure will be large, causing stress concentration and elastic fatigue, and reducing the service life of the helmet.

[0004] Therefore, it is necessary to develop a new type of lens driving device for helmets to improve some of the problems existing in related technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a lens driving device that can flexibly adjust the position and angle of the lens when the lens moves, so that the lens fits the target position better after moving.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0008] Furthermore, the driving member is provided with a second sliding part, which is movably disposed on the second guide rail structure on the bottom member, and the second sliding part is located on the side wall of the telescopic cavity.

[0009] Furthermore, the base component includes a first base plate and a second base plate, which are spaced apart. The first guide rail structure and the second guide rail structure are respectively located on the first base plate and the second base plate, and the driving component and the mounting component are located between the first base plate and the second base plate.

[0010] Furthermore, the driving member is provided with a third sliding part, which is movably disposed on the third guide rail structure on the bottom member. The openings of the third sliding part and the telescopic cavity are respectively located at both ends of the driving member.

[0011] Furthermore, the base component includes a first base plate, a second base plate, a third base plate, and a base component connecting plate. The first guide rail structure is located on the first base plate, the second guide rail structure is located on the second base plate, and the third guide rail structure is located on the third base plate. The ends of the first base plate, the second base plate, and the third base plate are respectively connected to the top area, the middle area, and the bottom area of ​​the base component connecting plate.

[0012] Furthermore, the first base plate and the third base plate are connected to one end of the bottom connecting plate in the width direction, and the second base plate is connected to the other end.

[0013] Furthermore, the first guide rail structure and the second guide rail structure are guide grooves, and the third guide rail structure is a guide ridge.

[0014] Furthermore, the telescopic cavity has guide holes spaced apart on its sidewalls, forming a hole bridge between the guide holes; the mounting member has two guide protrusions that extend into the guide holes and abut against the sidewalls of the hole bridge to guide the extension or retraction of the mounting member.

[0015] Furthermore, the width of the bridge gradually increases in the opening direction of the telescopic cavity.

[0016] Furthermore, the base component also includes a base component connecting plate, the ends of the first base plate and the second base plate are connected through the base component connecting plate, the base component connecting plate is provided with an operating hole, and the operating component passes through the operating hole to connect to the driving component.

[0017] Compared with the prior art, the lens driving device provided by the present invention has the following beneficial effects:

[0018] 1. The lens driving device of the present invention movably accommodates the mounting part within the telescopic cavity of the driving part. Through the cooperation between the first sliding part on the mounting part and the first guide rail structure on the bottom part, the driving part can extend or retract on the telescopic cavity when it moves the mounting part, guided by the first guide rail structure. This adjusts the relative distance and angle between the lens and the helmet surface, enabling flexible adjustment of the lens.

[0020] 3. In this invention, the base component is arranged with a gap between the first base plate and the second base plate, and the driving component and the mounting component are arranged between the first base plate and the second base plate. The first sliding part on the mounting component and the second sliding part on the driving component are respectively connected to the first guide rail structure and the second guide rail structure from both sides, so that the mounting component and the driving component are subjected to more uniform force when moving, and the structural reliability is better.

[0021] 4. The driving component in this invention has a third sliding part, and the openings of the third sliding part and the telescopic cavity are located at both ends of the driving component, making the movement at both ends of the driving component more stable and further improving the lens adjustment effect.

[0022] 5. In this invention, a guide hole is provided on the side wall of the telescopic cavity to form a hole bridge. The guide protrusion of the mounting component extends into the guide hole and is guided by the side of the hole bridge, which helps to improve the stability of the telescopic movement of the mounting component.

[0023] 6. The present invention gradually increases the width of the hole bridge on the telescopic cavity, thereby increasing the friction between the hole bridge and the guide protrusion after the mounting part extends out, thus enabling the lens to be fixed in the target position.

[0034] In some specific embodiments, reference is made to Figure 1 and Figure 2The base component 1 is fastened to the inner surface of the helmet body (not shown in the figure) by fasteners. Two sets of base components 1, mounting components 3, and driving components 4 are symmetrically arranged on both sides of the face opening. Both the driving component 4 and the mounting components 3 are mounted on the base component 1. The two ends of the lens 6 are connected to the mounting components 3 on both sides respectively. The operating component 5 is a rope, one end of which is connected to the driving component 4 and the other end is connected to the toggle switch 7 at the bottom of the helmet. When the toggle switch 7 is toggled, the rope drives the driving component 4 to move on the base component 1, which in turn drives the mounting component 3 on which the lens 6 is mounted to move, thereby adjusting the lens 6.

[0035] In some specific embodiments, the mounting member 3 has a mounting cavity formed thereon, and the bottom of the mounting cavity has a snap-fit ​​structure to fix the end of the lens 6.

[0036] In some specific embodiments, reference is made to Figure 2 and Figure 3 The first guide rail structure 21 is a guide groove, and the surface of the mounting part 3 is provided with a cylindrical first sliding part 31.
