Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
the first embodiment is as follows:
referring to fig. 1 and fig. 2, a locking mechanism 101 for a lens according to the present invention is provided. The locking mechanism 101 for lens includes a base 10, a lens support 20 rotatably disposed on the base 10, and a locking member 30 rotatably disposed on the base 10 and capable of blocking and engaging with the lens support 20.
Referring also to fig. 3, the base 10 is used to support other components of the locking mechanism 101 for the lens. The base 10 has an at least partially circular-arc profile. The base 10 includes a base body 14. In the present embodiment, the base body 14 has a substantially plate shape. The base 10 comprises a first rotary engagement portion 15. The first rotation engagement portion 15 may be engaged with a first rotation limiting portion 45 of the driving member 40 described below to rotate relative to each other. The first rotation fitting portion 15 is provided to project in the axial direction of the base 10. For the sake of simplicity and ease of assembly, the first rotating engagement portion 15 is a cylindrical shaft. More specifically, the first rotation fitting portion 15 is a cylindrical shaft. In order to make full use of the space of the base 10, the first rotation fitting portion 15 is provided at the center of the base 10.
To facilitate a rotational limit fit with the lock 30, the base 10 further includes a second rotational fit 16. In the present embodiment, the second rotation engagement portion 16 is a cylindrical shaft. Of course, the second pivot engagement portion 16 may protrude through a post, shaft-engaging hole. The second pivot-coupling portion 16 may be a hinge or the like. The position of the second rotation-fitting portion 16 is selected as needed. In the present embodiment, the second rotation engagement portion 16 is spaced apart from the first rotation engagement portion 15, i.e., is disposed away from the center of the base 10.
To enhance the restraint retention of the lock 30, the base 10 further includes a stop 17. The blocking portion 17 is disposed on a rotation path of the locking member 30 and is disposed to prevent the locking member 30 from being rotated. In the present embodiment, the blocking portion 17 is substantially boss-shaped. The blocking portion 17 serves to prevent the locking member 30 from reversely rotating. More specifically, the blocking portion 17 prevents the locking member 30 from rotating counterclockwise when the lens support 20 is in the locked position.
To enhance positive retention of the lens support 20, the base 10 further includes a retention flange 18. The holding flange 18 is provided to protrude in the radial direction of the base 10. The retaining flange 18 is disposed in the path of rotation of the lens support 20. The retention flange 18 is in blocking engagement with the retention flange 28 of the lens support 20. In particular, the retention flange 18 can prevent the lens support 20 from rotating excessively clockwise. Accordingly, the limiting flange 28 is arranged to prevent the lens 60 from being excessively turned over when the lens 60 is turned over backward and upward to keep eyes at the original position and separate from the shielding of the corresponding lens 60, thereby improving convenience and stability.
The other components of the base 10 are provided on the base body 10, unless otherwise specified. In this embodiment, the base 10 is an injection molded integral piece.
Referring also to fig. 4, the lens support 20 is used to support the lens 60. The lens support 20 is rotatably provided on the base 10. In the present embodiment, the lens holder 20 has a third rotation defining portion 21. In this embodiment, the third rotation limiting portion 21 is a limiting hole. The limiting hole can be a through hole which penetrates axially (in the direction perpendicular to the plane in the figure). The third rotation defining portion 21 is mated with the third rotation engaging portion 19 of the base 10 so as to be rotatably disposed relative to each other. In order to save space sufficiently, the third rotation limiting section 21 shares the same axis of rotation as the second rotation limiting section 48 of the drive element 40 described below. Accordingly, the third rotating engagement portion 19 and the first rotating engagement portion 15 have the same rotation axis.
The lens support 20 includes a rotation lock portion 25. The rotation-blocking portion 25 is used to block the locking member 30 from further rotating at a predetermined position. The rotation lock portion 25 may be any structure that can achieve blocking, such as a bump, a protruding tooth, or a cross bar. In order to make full use of space and simplify the layout, in the present embodiment, the rotation locking portion 25 is a U-shaped groove. The U-shaped groove is communicated with a limit hole formed by the third rotation limiting portion 21. Accordingly, the lens support 20 has a stop flange 28 that cooperates with the retention flange 18 of the base 10. The lens support 20 has an at least partially circular arc profile. In order to achieve force balance and make full use of space, the rotation locking portion 25 is disposed at the center of the lens support 20.
Referring also to fig. 5, the locking member 30 is rotatably disposed on the base 10. The locking piece 30 has a locking engagement portion 31. The lock engagement portion 31 is configured to be rotatable into a rotational limit engagement with the rotation locking portion 21. The locking engagement portion 31 may be any structure that satisfies the blocking engagement. In this embodiment, the locking engagement portion 31 is a convex pillar. More specifically, in order to sufficiently save manufacturing materials and to achieve rotation with less effort, the lock engagement portion 31 is provided on a first support arm 33 described below. The lock engagement portion 31 extends in the axial direction of the base 10.
To facilitate the reciprocal rotation, the locking member 30 includes a first support arm 33 and a second support arm 35 connected to each other. To save space substantially, one end of the first support arm 33 is connected to the other end of the second support arm 35. The first supporting arm 33 and the second supporting arm 35 are arranged at a certain included angle. The specific size range of the included angle is selected according to the requirement, and can be an acute angle, a right angle or an obtuse angle. The second support arm 35 has a stop 37. The stopper 37 is provided on a rotation path of an abutting portion 44 of a driver 40 described below, and is provided so as to block the abutting portion 44, thereby preventing the abutting portion 44 from continuing to rotate in the reverse direction when the lock engagement portion 31 is engaged with the rotation lock portion 21 in a limit manner.
The lock 30 further includes a second rotation limiting portion 39. In this embodiment, the second rotation limiting portion 39 is a limiting hole. The second rotation limiting portion 39 is mated with the second rotation engaging portion 16 on the base 10 so as to be rotated relative to each other. In order to be evenly stressed and save space, in the present embodiment, the second rotation limiting portion 39 is provided at the junction of the first support arm 33 and the second support arm 35. In this embodiment, the locking element 30 is an injection molded part.
It is contemplated that the lock 30 may be pushed directly when it is desired to adjust the relative position of the lens support 20. Referring to fig. 6, in the present embodiment, in order to facilitate the effort-saving and easy-to-operate pushing of the locking member 30, the lens locking mechanism 101 further includes a driving member 40. The driving member 40 is reciprocally disposed on the base 10. The driving member 40 is coupled to the locking member 30 and drives the locking engagement portion 31 to rotate. To facilitate manual operation, the drive member 40 includes a linkage 41. One end of the link 41 is provided with a link push handle 43. The link pusher 43 is disposed to protrude with respect to the base 10. To facilitate a labor-saving operation, in the present embodiment, the driving member 40 includes an abutment 44. The abutment 44 may abut the lock 30 and push the lock 30. In the present embodiment, the abutting portion 44 may be rotated to abut against the first support arm 33 and the second support arm 35. Specifically, when the contact portion 44 contacts the first support arm 33, the first support arm 33 is driven to rotate in the forward direction. When the contact portion 44 contacts the second support arm 35, the second support arm 35 is driven to rotate in the reverse direction. When the first supporting arm 33 rotates forward, the locking matching part 31 is driven to be in limit matching with the rotation limit matching part 21. When the second support arm 35 rotates reversely, the locking engagement portion 31 is driven to disengage from the rotation locking portion 21. The driving member 40 further includes a first rotation limiting portion 45. In this embodiment, the first rotation limiting portion 45 is provided at one end of the driving member 40. The first rotation limiting portion 45 is a limiting hole. Further, the first rotation defining part 45 is a through hole. The first rotation limiting portion 45 is provided to be opposed to the third rotation engagement portion 19. Accordingly, the first rotation limiting portion 45 and the third rotation limiting portion 21 have a common rotation axis, i.e. the driving member 40 and the lens support 20 have a common rotation axis, i.e. are coaxially rotatable.
Preferably, the locking mechanism 101 for lens is a screw-free assembly. That is, in the present embodiment, the locking mechanism 101 for a lens can be assembled and fastened without using a fastener such as a screw. Each component of the locking mechanism 101 for a lens is an injection molded part. All the parts of the invention are connected without screws, thus reducing unpredictable pressure combination between screws and plastics, and under the working state of the lens locking device, the locking mechanism is meshed with strength to the maximum extent, thus effectively enhancing the strength of the mechanism, and when the locking mechanism operates, if misoperation occurs, all forces are concentrated in the U-shaped notch 25 of the lens made of PC material, and the whole locking mechanism has no obvious effect, therefore, the invention has the characteristics of low failure rate, high reliability and convenient maintenance. In addition, because the exposed locking mechanism part is only the push handle 43 of the connecting rod, the movement path of the locking mechanism part is also consistent with the circular periphery of the lens base, the locking mechanism part is very good in integration with the product, and the overall design style of the product cannot be influenced.
Example two:
with continued reference to fig. 1 and 2, the present invention further provides a lens assembly 103. The perspective of the lens assembly 103 being worn vertically on a human head is shown in both fig. 1 and 2. Accordingly, the lens 60 is directly in front of the angle of view of the human eye in the left direction in the drawing. The lens assembly 103 includes a lens 60 and the locking mechanism 101 for the lens. The lens 60 is disposed on the lens support 20. Further, in the present embodiment, the lens 60 and the lens support 20 are a single piece to provide sufficient material savings, simplify the manufacturing process, and provide a stable support. More specifically, the lens 60 and the lens support 20 are injection molded parts. In this embodiment, the lens 60 is a visor for a helmet. The lenses 60 may also be lenses such as for near vision glasses, presbyopic glasses, etc., depending on the application. The shape of the lens 60 is sufficient to meet the corresponding protection requirements. The pair of locking mechanisms 101 for lens is provided to stably support the lens 60. The pair of locking mechanisms 101 for lenses are connected to both sides of the lens 103, respectively, and are provided on both side walls of a shell of a helmet described below, respectively. The lens 60 is disposed to protrude from the base 10.
During assembly, the lens support 20 with the lens 60 is disposed on the base 10, and the third rotation limiting portion 21 with a limiting hole is correspondingly sleeved on the third rotation matching portion 19 with a shaft shape. The rotating member 40 is provided on the base 10 such that the first rotation engaging portion 45, which is a link rotation axis, is provided at the first rotation engaging portion 15 common to the third rotation engaging portion 19. The lens support member 20 and the rotating member 40 are axially stacked. The slider 30 is disposed on the base 10 such that the second rotation defining portion 39 is disposed on the second rotation engaging portion 16 in the form of a shaft.
Example three:
the present invention also provides a helmet (not shown in the figures). The helmet comprises the lens component 103 as described in example two. It will be appreciated that the helmet may also include a shell to accommodate the head, a cushioning mechanism, etc. The base 10 can be fixedly arranged on the shell of the helmet.
In this embodiment, the lens holder 20, the locking member 30 and the driving member 30 can be rotated in a reciprocating manner, i.e., in a forward direction and a reverse direction, i.e., in a clockwise direction and a counterclockwise direction, unless otherwise specified. The "axial direction" appearing in the present invention, such as the axial direction of the base 10, refers to the axial direction of rotation of other components relative to the base 10, that is, the direction protruding perpendicular to the paper as in fig. 1. In addition, "forward" and "reverse" are relative concepts. In the present embodiment, for convenience of describing the relative rotation relationship of the respective components with reference to the drawings, the "forward direction" is a clockwise direction, and the "reverse direction" is a counterclockwise direction. Accordingly, the rotation direction is along the circumferential direction of the base 10.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
