BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of an angle adjusting mechanism according to an embodiment of the present invention. 2 is an exploded view of the angle adjustment mechanism of FIG. 1. 3 is a partial cross-sectional view of the angle adjusting mechanism of FIG. 1. Referring to FIG. 1 to FIG. 3 , in the embodiment, the angle adjustment mechanism 100 includes a first body 110 , a second body 120 , a pivot 130 , and a reset member 140 . The second body 120 is movably coupled to the first body 110, wherein the first body 110 has a first positioning structure, which is, for example, a plurality of positioning recesses 112, and the second body 120 has a The positioning structure is, for example, a positioning protrusion 122, and the positioning protrusion 122 is correspondingly embedded in one of the positioning recesses 112, so that the second positioning structure and the first positioning structure are fitted to each other, thereby fixing the first body 110. The angle between the second body 120 and the second body 120. Furthermore, the pivot 130 is disposed between the first body 110 and the second body 120 along the axial direction A1. As such, the second body 120 is adapted to be rotated relative to the first body 110 in the axial direction A1 by the pivot 130 such that the second positioning structure is away from the first positioning structure in the radial direction R1. In other words, the positioning protrusion 122 as the second positioning structure is adapted to move out of the corresponding positioning recess 112 in the radial direction R1 when the second body 120 is rotated relative to the first body 110 in the axial direction A1. In addition, the reset member 140 is coupled to the second body 120, wherein the reset member 140 can be a coil spring or other suitable component, and the invention is not limited thereto. As such, the reset member 140 can be deformed as the second body 120 moves. Thereby, the restoring member 140 is adapted to accumulate the restoring force when the positioning convex portion 122 moves out of the corresponding positioning concave portion 112 in the radial direction R1 and the second positioning structure away from the first positioning structure in the radial direction R1, and the second positioning structure is adapted to After the second body 120 is rotated by an angle with respect to the first body 110, the first positioning structure is approached in the radial direction R1 by the restoring force to re-engage with each other. That is, after the positioning protrusion 122 moves out of the corresponding positioning recess 112, the second body 120 is also rotated by an angle with respect to the first body 110. Thus, the positioning convex portion 122 as the second positioning structure can be approached in the radial direction R1 and embedded in the other of the positioning concave portions as the first positioning structure by the returning force of the resetting member 140 to re-engage with each other. Therefore, after the first body 110 and the second body 120 are rotated relative to each other, the positioning protrusion 122 can be embedded in the other positioning recess 112 by the restoring force of the resetting member 140, thereby fixing the first body 110 and the second body again. The angle between 120.

Specifically, in the embodiment, the angle adjusting mechanism 100 further includes a fixing base 150 and a support member 160. The fixing base 150 has an accommodation space 152. The support member 160 is disposed at one side of the fixing base 150 and communicates with the accommodating space 152. The fixing base 150 connects the first body 110 and the second body 120. Further, the first body 110, the second body 120 and the fixing base 150 are pivoted together by the pivot 130, wherein the second body 120 is located between the first body 110 and the fixing base 150, and the second body The bottom portion 124 of the positioning protrusion 122 is located in the accommodating space 152. Thus, the fixing base 150 is adapted to rotate relative to the first body 110 in the axial direction A1 by the pivot 130, and to rotate the second body 120 relative to the first body 110 and move in the accommodating space 152. Moreover, in the present embodiment, the second body 120 has a chute 126, and the pivot 130 is disposed within the chute 126. As such, the second body 120 is adapted to be moved relative to the pivot 130 by the sliding slot 126 to move the positioning protrusion 122 in the radial direction R1 or into the corresponding positioning recess 112, while moving the second positioning structure away from the radial direction R1. Or close to the first positioning structure, and the bottom 124 of the second body 120 can move within the accommodating space 152. In other words, when the fixing base 150 is rotated relative to the first body 110 in the axial direction A1 by the pivot 130, the second body 120 is rotated by the fixing base 150 to rotate relative to the first body 110. During the rotation of the second body 120 relative to the first body 110 by the pivot 130 in the axial direction A1, the positioning protrusion 122 can be moved relative to the pivot 130 by the sliding slot 126 while being removed or embedded in the radial direction R1. Corresponding positioning recesses 112 are moved relative to the mount 150. The reset member 140 is disposed in the accommodating space 152 , and the reset member 140 is connected between the bottom portion 124 of the second body 120 facing the accommodating space 152 and the support member 160 . As such, the second body 120 is positioned at the convex portion When the corresponding positioning recess 112 is removed in the radial direction R1, the reset member 140 is compressed, and the reset member 140 is deformed in the accommodating space 152 to accumulate the restoring force. After the positioning protrusion 122 is removed from the corresponding positioning recess 112 in the radial direction R1, the first body 110 and the second body 120 are also rotated by an angle, so that the positioning protrusion 120 faces the other positioning recess 112. Therefore, after the positioning convex portion 122 moves out of the corresponding positioning concave portion 112 in the radial direction R1, the resetting member 140 deforms in the accommodating space 152 to release the restoring force to push the second body 120 toward the first body 110 by the restoring force. The movement is made and the positioning convex portion 122 is fitted into the other positioning concave portion 112 in the radial direction R1.

4 is a schematic view of the first body of FIG. 1. Referring to FIG. 1 to FIG. 4 , in the embodiment, each of the positioning concave portion 112 and the positioning convex portion 122 has an elongated shape. For example, each of the positioning recesses 112 may be a strip-shaped recess, and the positioning protrusions 122 may be strip-shaped ribs. The extending direction of each positioning concave portion 112 and the extending direction of the positioning convex portion 122 are parallel to each other. As such, the positioning recesses 112 are arranged parallel to each other, and the shape of the positioning protrusions 122 substantially corresponds to the positioning recesses 112, so that the positioning protrusions 122 can be embedded in the corresponding positioning recesses 112. Furthermore, each of the above extending directions is parallel to the axial direction A1. As such, when the second body 120 is rotated relative to the first body 110 in the axial direction A1, and the positioning protrusion 122 is moved out or embedded in the corresponding positioning recess 112, the positioning protrusion 122 can be regarded as being moved after the corresponding positioning recess 112 is removed. The direction N1 (shown in FIG. 4) perpendicular to the axial direction A1 is displaced forward or backward and embedded in the adjacent another positioning recess 112. Moreover, in the embodiment, since the positioning convex portion 122 can be embedded in the corresponding positioning concave portion 112 by the restoring force of the resetting member 140, the size of the positioning concave portion 112 and the positioning convex portion 122 also affect the operation of the angle adjusting mechanism 100. the way. For example, when the depth of the positioning recess 112 is deep, the second body 120 generates a more significant displacement when the positioning protrusion 122 is removed or embedded in the corresponding positioning recess 112. As such, the angle adjustment mechanism 100 has a good operational feel. Further, in the present embodiment, the contour of each positioning recess 112 corresponds to the contour of the positioning convex portion 122. For example, the contours of the positioning recesses 112 and the positioning protrusions 122 may be circular or other curved in cross section, as shown in FIG. As such, the positioning projection 122 is adapted to move or embed the corresponding positioning recess 112 along the surface of the corresponding positioning recess 112. In other words, by designing the contours of the positioning recesses 112 and the positioning projections 122 to correspond to each other, preferably designed to assume a circular arc shape, the process of removing or embedding the positioning projections 122 into the corresponding positioning recesses 112 is further improved. Smooth.

Therefore, in this embodiment, by configuring on the first body 110 The plurality of positioning recesses 112 allow the first body 110 and the second body 120 to be positioned at a plurality of different predetermined positions via relative rotation. In other words, after the first body 110 and the second body 120 are rotated relative to each other to adjust the use angle of the angle adjustment mechanism 100, the first body 110 and the second body 120 can be positioned by the positioning protrusion 122 matching one of the positioning recesses 112. To fix the angle between the first body 110 and the second body 120. Moreover, the resetting member 140 can accumulate or release the restoring force by rotating the first body 110 and the second body 120 relative to each other, so that the first body 110 and the second body 120 are rotated by a predetermined position. Automatically positioned. In addition, when the second body 120 has not pushed the reset member 140 and the positioning protrusion 122 has been embedded in one of the positioning recesses 112, the reset member 140 may also have a restoring force, for example, the coil spring as the reset member 140 is appropriate first. Configured in the second body after compression The bottom 124 of the 120 is between the support member 160. As such, the reset member 140 can enhance the fixation between the positioning protrusion 122 and the positioning recess 112 by the restoring force. Thereafter, the angle adjusting mechanism 100 can adjust the angle between the first body 110 and the second body 120 by an external force, so that the second body 120 compresses the reset member 140 while rotating relative to the first body 110, thereby The reset member 140 accumulates more restoring force, and then pushes the second body 120 toward the first body 110 by releasing the restoring force, thereby embedding the positioning protrusion 120 into the corresponding positioning recess 112. It can be seen that, by the design of the reset member 140, the first body 110 and the second body 120 can be automatically positioned by the restoring force after being rotated to a predetermined position, and have good bonding.

Fig. 5 is a perspective view of an angle adjusting mechanism according to another embodiment of the present invention. Figure 6 is an exploded view of the angle adjustment mechanism of Figure 5. Fig. 7 is a partial cross-sectional view of the angle adjusting mechanism of Fig. 5; Figure 8 is a side elevational view of the first body of Figure 5. Referring to FIG. 5 to FIG. 8 , in the embodiment, the angle adjusting mechanism 100 a includes a first body 110 a , a second body 120 a , a pivot 130 , a resetting member 140 , and a fixing seat 150 a . The first body 110a has a first positioning structure, which is, for example, a plurality of positioning recesses 112a. The second body 120a has a second positioning structure, which is, for example, a plurality of positioning protrusions 122a, and each positioning protrusion 122a is correspondingly embedded in the positioning recess. One of the 112a is such that the second positioning structure and the first positioning structure are fitted to each other, thereby fixing the angle between the first body 110a and the second body 120a. Moreover, the second body 120a can be rotated relative to the first body 110a in the axial direction A2 by the pivot 130 by the pivot 130 and the reset member 140, and the positioning convex portion 122a can be moved in the radial direction R2. Positioning the recess 112a such that the second positioning structure is away from the first positioning structure in the radial direction R2, and the reset member 140 is in the positioning convex portion The resetting force is accumulated when 122a moves out of the corresponding positioning recess 112a in the radial direction R2. Thus, after the positioning convex portion 122a is removed from the corresponding positioning concave portion 112a, the positioning convex portion 122a can be inserted into the other positioning concave portion 112a in the radial direction R2 by the restoring force of the resetting member 140, thereby repositioning the first body 110a and the second portion. Body 120a. It can be seen that the angle adjustment mechanism 100a has a similar structure and function as the angle adjustment mechanism 100 described above. For the relative position, connection relationship and actuation manner of the first body 110a, the second body 120a, the pivot 130 and the restoring member 140, reference may be made to the foregoing, the main difference being the positioning recess 112a, the positioning protrusion 122a and the fixing seat 150a.

Specifically, in the embodiment, the first body 110a, the second body 120a and the fixing base 150a are pivoted together by the pivot 130, wherein the second body 120a is located between the first body 110a and the fixing seat 150a. The second body 120a is located in the accommodating space 152 with respect to the bottom portion 124 of the positioning convex portion 122a. As such, the first body 110, the second body 120, the reset member 140 and the fixed seat 150 can be referred to the relative position, the connection relationship and the actuation manner of the first body 110a, the second body 120a, the resetting member 140 and the fixing base 150a. I will not repeat them here. However, unlike the previous embodiment, the fixing base 150a of the present embodiment is not provided with the aforementioned support member 160, wherein the resetting member 140 is located in the accommodating space 152 and is connected to the second body 120a facing the accommodating space 152. Between the bottom portion 124 and the inner portion 154 of the fixing seat 150a, a deformation force is accumulated in the accommodating space 152 to accumulate or release the restoring force. In other words, the fixing seat 150a of the present embodiment can be regarded as the combination of the aforementioned fixing seat 150 and the support member 160. As can be seen, the present invention does not limit the specific shape of the mount.

Furthermore, in the present embodiment, the positioning concave portion 112a and the positioning convex portion 122a The number is respectively plural, and the positioning concave portion 112a and the positioning convex portion 122a correspond to each other. The positioning concave portion 112a and the positioning convex portion 122a have an elongated shape, for example, a strip-shaped groove as the positioning concave portion 112a, and a strip-shaped convex rib as the positioning convex portion 122a. The extending direction D of each positioning concave portion 112a and the extending direction D of each positioning convex portion 122a are parallel to each other. Thus, the positioning concave portion 112a and the positioning convex portion 122a are arranged in parallel with each other, and the shape of the positioning convex portion 122a substantially corresponds to the positioning concave portion 112a, so that the positioning convex portion 122a can be embedded in the corresponding positioning concave portion 112a. Further, in the present embodiment, the first body 110a has a recess 114 on one side of the positioning recess 112a. After at least one of the positioning convex portions 122a is moved out of the positioning concave portion 112a, the positioning convex portion 122a positioned outside the positioning concave portion 112a is positioned in the concave groove 114. In this manner, the second body 120a is rotatable relative to the first body 110a to the positioning convex portion 122a arranged at the lowermost position, and is disposed in the uppermost positioning concave portion 112a, and the remaining positioning convex portions 122a are moved into the groove 114 without interfering with the first portion. Relative rotation between a body 110a and the second body 120a.

Further, in the present embodiment, the extending direction D and the axial direction A2 of each of the positioning concave portions 112a and the respective positioning convex portions 122a are not parallel to each other and have an included angle θ. In other words, the positioning concave portion 112a and the positioning convex portion 122a can be regarded as being obliquely arranged with respect to the moving direction of the first body 110a and the second body 120a. Thereby, when the second body 120a is rotated relative to the first body 110a by the pivot 130 in the axial direction A2, and the positioning convex portion 122a is moved out or embedded in the corresponding positioning concave portion 112a in the radial direction R2, the positioning convex portion 122a is visible. After the corresponding positioning recess 112a is removed, it is displaced forward or backward in a direction N2 perpendicular to the axial direction A2 and embedded in the adjacent another positioning recess 112a. In addition, due to The positioning concave portion 112a of the present embodiment and the positioning convex portion 122a are obliquely arranged, so that the frictional force generated when the positioning convex portion 122a is removed from the corresponding positioning concave portion 112a can generate a component force in the extending direction D of the positioning concave portion 112a, thereby When the positioning convex portion 122a is inserted into or removed from the corresponding positioning concave portion 112a in the direction N2, the influence of the frictional force on the positioning convex portion 122a and the positioning concave portion 112a is reduced. Thus, the aforementioned angle θ is preferably greater than or equal to 0 degrees and less than 90 degrees, but the invention is not limited thereto. With the above design, by adjusting the angle θ between the extending direction D and the axial direction A2, the frictional force generated by the relative movement between the positioning convex portion 122a and the corresponding positioning concave portion 112a can generate a component force in the extending direction D. The wear between the positioning convex portion 122a and the positioning concave portion 112a is reduced, thereby increasing the life cycle of the angle adjusting mechanism 100a.

Accordingly, in the present embodiment, the first body 110a and the second body 120a can be positioned at a plurality of different predetermined positions by arranging a plurality of positioning recesses 112a on the first body 110a. In other words, after the first body 110a and the second body 120a are rotated relative to each other to adjust the use angle of the angle adjusting mechanism 100a, the first body 110a and the second body 120a can be positioned by the positioning convex portion 122a matching the positioning concave portion 112a. Furthermore, in the present embodiment, the positioning concave portion 112a and the positioning convex portion 122a can also increase the operational feel by adjusting the size thereof, and the contours of the positioning concave portion 112a and the positioning convex portion 122a are designed to correspond to each other, preferably a design. The process of forming the arc shape can also make the process of removing or embedding the positioning convex portion 122a into the corresponding positioning concave portion 112a. For the related content, refer to the foregoing description, and no further details are provided herein. In addition, by the design of the reset member 140, the first body 110a and the second body 120a can be automatically positioned by the restoring force after being rotated to a predetermined position, and have good bonding.

Further, the first positioning structure and the second positioning structure of the present invention are not limited to the above-described types. For example, in other embodiments, the first positioning structure of the first body may be a positioning recess, and the second positioning structure of the second body 120 may be a plurality of positioning protrusions, that is, the embodiment and the foregoing implementation. The difference in the example is the number of positioning recesses and positioning projections. Thereby, one of the positioning protrusions can also be correspondingly embedded in the positioning recess, and the second positioning structure and the first positioning structure are fitted to each other, thereby fixing the angle between the first body and the second body, and The angle between the first body and the second body is adjusted and fixed again by the above method. Similarly, the first positioning structure and the second positioning structure may be interchanged, that is, the first positioning structure of the first body may be a positioning convex portion, and the second positioning structure of the second body may be a positioning concave portion. And one of the positioning recesses as the second positioning structure is correspondingly embedded in the positioning convex portion as the first positioning structure. Alternatively, the first positioning structure of the first body may be a plurality of positioning protrusions, and the second positioning structure of the second body may be a positioning recess, and the positioning recess as the second positioning structure may be correspondingly embedded as the first positioning. One of the positioning projections of the structure. The above-mentioned first positioning structure and the second positioning structure can also be fitted to each other to achieve the effect of fixing the angle between the first body and the second body, and the first body and the first body can be adjusted and re-fixed by the above method. The angle between the two bodies. It can be seen that the present invention does not limit the specific types of the first positioning structure and the second positioning structure, which can be adjusted according to requirements.

In summary, in the angle adjusting mechanism of the present invention, the first body has a first positioning structure, which is, for example, a plurality of positioning recesses, and the second body has a second positioning structure, which is, for example, a positioning protrusion, and is positioned. The convex part is correspondingly embedded in the corresponding fixed The recess is configured such that the first positioning structure and the second positioning structure are fitted to each other to fix the angle between the first body and the second body. Furthermore, the second body is adapted to be rotated in the axial direction relative to the first body to adjust the angle. At this time, the second positioning structure is radially away from the first positioning structure to move the positioning protrusions radially out of the corresponding positioning recesses, and the resetting member coupled to the second body accumulates the restoring force. Thereby, the second positioning structure can radially approach the first positioning structure by the restoring force after the second body is rotated by an angle with respect to the first body, thereby fixing the angle between the first body and the second body again. In addition, by the design of the resetting member, the first body and the second body can be automatically positioned by the restoring force after being rotated to a predetermined position, and have good bonding. Accordingly, the angle adjusting mechanism of the present invention has a positioning function, and the first body and the second body can be adjusted in angle by rotation and positioned after being rotated.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
