The present invention relates to an angular adjusting and positioning device, and more particularly to a three-dimensional angular adjusting and positioning device.
With the popularization of common electronic equipment, users choose such electronic equipment on consideration of the convenience of installation, and also expect that the installed electronic equipment can be adjusted in multiple angles and positioned at a specific angle according to the different requirements of the applied environments.
An electronic equipment on a transportation vehicle is taken as an example, wherein a common adjustable screen or a satellite antenna usually needs to be adjusted according to a specific applied environments or actual application requirements, and further positioned at a specific angle. However, such electronic equipment must be completely positioned at a specific angle during use and cannot be carried by a conventional universal rotating shaft due to the heavier weight thereof. Hence, the angular adjusting and positioning functions cannot be simultaneously achieved by the conventional universal rotating shaft.
On the other hand, the angular adjusting and positioning device commonly used in such electronic equipment on the current market only provides the angular adjusting function on two-dimensional such as horizontal plane, and achieves simple positioning by high frictional resistance. In that, the range of the adjustable angle is limited, the operation of the electronic equipment is time-consuming to adjust angle due to the high frictional resistance and it fails to meet the actual application requirements.
Therefore, there is a need of providing a three-dimensional angular adjusting and positioning device capable of carrying an electronic equipment mounted thereon and providing the mounted and carried electronic equipment with the angular adjusting and positioning functions at the same time, so as to address the above-mentioned issues.
An object of the present invention is to provide a three-dimensional angular adjusting and positioning device. With an eccentric cam rotated by a single arm to switch the relative positions of the components, the engaging portions of the components are driven to separate or engage. Thereby, the three-dimensional angular adjusting and positioning device can be freely adjusted and positioned at a specific angle according to the practical requirements. Moreover, an electronic equipment can be mounted and carried thereon simply and it benefits to avoid the angular displacement of the mounted and carried electronic equipment due to the collision or the gravity.
Another object of the present invention is to provide a three-dimensional angular adjusting and positioning device for simply mounting and carrying an electronic equipment and facilitating the mounted and carried electronic equipment to achieve a three-dimensional angular adjustment and position. The structure of the three-dimensional angular adjusting and positioning device is compact and can be assembled easily. With an eccentric cam rotated by a single arm to switch the relative positions of the components, the engaging portions of the components are driven to separate or engage. Thereby, an electronic equipment mounted and carried on the three-dimensional angular adjusting and positioning device can be freely adjusted and positioned at a specific angle according to the practical requirements. It also benefits to avoid the angular displacement of the mounted and carried electronic equipment due to the collision or the gravity.
Other object of the present invention is to provide a three-dimensional angular adjusting and positioning device. The structure of the three-dimensional angular adjusting and positioning device is compact and can be assembled easily. The angular adjusting and positioning operations are performed without an additional tool. An eccentric cam disposed therein can be rotated by a single arm to switch the relative positions of the components, and the engaging portions of the components are driven to separate or engage, so as to achieve the operations of fastening or unfastening. It facilitates the three-dimensional angular adjusting and positioning device to be freely adjusted and positioned at a specific angle according to the practical requirements and then fastened firmly at the specific angle.
In accordance with an aspect of the present invention, a three-dimensional angular adjusting and positioning device is provided and includes a fixing member, a first adjusting member and a second adjusting member. The fixing member includes a base portion, a first engaging portion, a first shaft and a ring portion. The first engaging portion is disposed on the base portion. The ring portion includes a sleeving opening. The ring portion and the base portion are in connection with two opposite ends of the first shaft, respectively.

The accommodation opening is in communication with a first end of the shaft channel, and the first adjusting member is pivotally connected with the fixing member by the first shaft located through the shaft channel so as to rotate the first adjusting member to a first specific angle relative to the fixing member around the first shaft. The ring portion of the fixing member is accommodated within the accommodation opening, the second engaging portion is matched with the first engaging portion and disposed adjacent to a second end of the shaft channel, and the third engaging portion and the at least one inclined plane are disposed adjacent to two opposite ends of the accommodation opening, respectively. The second adjusting member includes a first sub-member and a second sub-member disposed adjacent to the two opposite ends of the accommodation opening, respectively. The first sub-member includes a fourth engaging portion matched with the third engaging portion. The second sub-member includes a second shaft, an eccentric cam, at least one pushing portion and an arm. The at least one pushing portion is matched with the at least one inclined plane, the second shaft runs through the accommodation opening and the ring portion, and the first sub-member is connected with the second shaft to rotate to a second specific angle relative to the first adjusting member around the second shaft. The eccentric cam is disposed around the second shaft and received within the sleeving opening of the ring portion. When the arm drives the second sub-member to rotate to a specific position relative to the first adjusting member around the second shaft, the at least one pushing portion abuts against the at least one inclined plane to drive the fourth engaging portion of the first sub-member to engage with the third engaging portion of the first adjusting member, and the eccentric cam abuts against the ring portion to drive the second engaging portion of the first adjusting member to engage with the first engaging portion of the fixing member, so that the first adjusting member and the first sub-member of the second adjusting member are positioned at the first specific angle and the second specific angle, respectively.

In the embodiment, the mounting ring set 27 is disposed within the accommodation opening 21 and partially covering around the outer edge of the ring portion 14, so that the ring portion 14 is limited within the accommodation opening 21. In the embodiment, the first adjusting member 20 includes a plurality of positioning slots 21a located through the accommodation opening 21 and disposed around the accommodation opening 21. Moreover, the mounting ring set 27 further including a plurality of supporting pins 27a spatially corresponding to the plurality of positioning slots 21a and disposed around the ring portion 14, so that the mounting ring set 27 is firmly mounted in the accommodation opening 21 and the ring portion 14 is limited in the accommodation opening 21. In the embodiment, the mounting ring set 27 further includes a through opening 27b aligned with the sleeving opening 14a of the ring portion 14.
In the embodiment, the second adjusting member 30 includes a first sub-member 40 and a second sub-member 50 disposed adjacent to the two opposite ends of the accommodation opening 21 of the first adjusting member 20, respectively. In the embodiment, the first sub-member 40 includes a fourth engaging portion 41. The fourth engaging portion 41 is spatially corresponding to the third engaging portion 24 of the first adjusting member 20. In addition, the second sub-member 50 is spatially corresponding to the first sub-member 40 and disposed adjacent to another opposite end of the accommodation opening 21. The second sub-member 50 includes a second shaft 55, an eccentric cam 53, at least one pushing portion 52 and an arm 51. The at least one pushing portion 52 is match with the at least one inclined plane 25 of the first adjusting member 20. The first sub-member 40 and the second sub-member 50 are pivotally connected with each other through the second shaft 55 and maintained a fixing distance. Moreover, the second shaft 55 runs through the accommodation opening 21 of the first adjusting member 20, the sleeving opening 14a of the ring portion 14 of the fixing member 10 and the through opening 27 of the mounting ring set 27 of the first adjusting member 20, and is connected with the first sub-member 40. Thus, the first sub-member 40 of the second adjusting member 30 can be freely rotated to a second specific angle relative to the first adjusting member 20 around the second shaft 55. In the embodiment, the second sub-member 50 further includes a second fastening hole 54 disposed thereon. The second shaft 55 includes a pivoting end 55a and a stopper end 55b disposed relative to each other and disposed on two opposite ends of the second shaft 55. The stopper end 55b is mounted on an end of the second fastening hole 54.

The pivoting end 55a is pivotally connected with a pivoting hole 42 of the first sub-member 40, so that the first sub-member 40 can be rotated freely around the second shaft 55.
It is noted that, the eccentric cam 53 of the second sub-member 50 is disposed on the second shaft 55. For example, the second shaft 55 runs through the eccentric cam 53, and is accommodated within the sleeving opening 14a of the ring portion 14 of the fixing member 10. In another embodiment, the eccentric cam 53 and the second shaft 55 are integratedly formed into one piece. It should be emphasized that the combining method for the eccentric cam 53 and the second shaft 55 is not an essential feature to limit the present disclosure, and not redundantly described herein. In the embodiment, the fixing member 10 includes a first elastic component 15, which can be for example but not limited to a spring, disposed between the fixing member 10 and the first adjusting member 20, so that the second engaging portion 23 of the first adjusting member 20 and the first engaging portion 12 of the fixing member 10 are maintained to space apart and not engage with each other. In that way, the first adjusting member 20 can be rotated freely to the first specific angle relative to the fixing member 10 around the first shaft 13. Furthermore, the ring portion 14 accommodated within the accommodation opening 21 of the first adjusting member 20 is rotated synchronously to drive the second adjusting member 30 to rotate. Namely, the first adjusting member 20 of the three-dimensional angular adjusting and positioning device 1 is set in an adjustable state, as shown in
On the other hand, as shown in
In other words, when the arm 51 drives the second sub-member 50 to rotate around the second shaft 55 and misalign the above specific position, the at least one pushing portion 52 of the second sub-member 50 is shifted away from the at least one inclined plane 25 of the first adjusting member 20. At the same time, the eccentric cam 53 releases the inner wall of the ring portion 14 of the fixing member 10 and not in abutting with the ring portion 14. Thus, the first elastic component 15 drives the second engaging portion 23 of the first adjusting member 20 to move away the first engaging portion 12 of the fixing member 10. At the same time, the second elastic component 45 drives the fourth engaging portion 41 of the first sub-member 40 to move away the third engaging portion 24 of the first adjusting member 20. In that way, the three-dimensional angular adjusting and positioning device 1 is set in the adjustable state, as shown in
In the embodiment, the first sub-member 40 further includes a mounting portion 43 disposed on an edge of the first sub-member 40. When the first adjusting member 20 is rotated to the first specific angle relative to the fixing member 10 around the first shaft 13 and the first sub-member 40 is rotated to the second specific angle relative to the first adjusting member 20 around the second shaft 55, a relative angle is formed between the mounting portion 43 and the fixing member 10. The mounting portion 43 includes for example but not limited a screw thread, so that an electronic equipment, such as a screen, an antenna or other electron equipment, can be mounted and carried on the mounting portion 43. Thus, the mounted and carried electronic equipment, such as the screen, the antenna or the other electronic equipment can be adjusted freely to achieve a specific angle according to the practical requirements and fastened at a specific position firmly. Certainly, the mounted and carried electronic equipment, such as the screen, the antenna or the other electronic equipment won't influence the operation of the three-dimensional angular adjusting and positioning device 1. In an embodiment, the electronic equipment, such as the screen, the antenna or the other electronic equipment, is mounted and carried on the mounting portion 43 after the three-dimensional angular adjusting and positioning device 1 is adjusted and positioned at the relative angle. In another embodiment, the electronic equipment, such as the screen, the antenna or the other electronic equipment, is mounted and carried on the mounting portion 43 firstly, and then the three-dimensional angular adjusting and positioning device 1 is adjusted and positioned at the relative angle. Thereby, it avoids the angular displacement of the mounted and carried electronic equipment due to the collision or the gravity. In the embodiment, the first sub-member 40 further includes an accommodation groove 44 disposed adjacent to the mounting portion 43. The accommodation groove 44 is used for receiving a power cable or signal line of the installed electronic equipment, such as the screen, the antenna or the other electronic equipment. Certainly, the type of the mounting portion 43 and the accommodation groove 44, the installation angle, and the relative positions of each other can be adjusted according to the practical requirements, and not redundantly described herein. In addition, it should be emphasized that the mounting portion 43 of the three-dimensional angular adjusting and positioning device 1 is not limited to mount and carry the electronic equipment. In another embodiment, the mounting portion 43 of the three-dimensional angular adjusting and positioning device 1 is used for mounting and carrying a lamp, a flag, a fishing tackle or a support frame. It is not an essential feature to limit the present disclosure and not redundantly described herein.
In the embodiment, the first engaging portion 12 and the second engaging portion 23 are for example located around the outer edge of the first shaft 13. Thus, when the first adjusting member 20 is rotated freely to the first specific angle relative to the fixing member 10 around the first shaft 13, the first engaging portion 12 is maintained to align with the second engaging portion 23. Furthermore, when the arm 51 drives the second sub-member 50 to rotate to the specific position relative to the first adjusting member 20 around the second shaft 55, the first engaging portion 12 and the second engaging portion 23 are engaged with each other. Similarly, the third engaging portion 24 and the fourth engaging portion 41 are for example located around the outer edge of the second shaft 55. Thus, when the first sub-member 40 of the second adjusting member 30 is rotated freely to the second specific angle relative to the first adjusting member 20 around the second shaft 55, the third engaging portion 24 is maintained to align with the fourth engaging portion 41. Furthermore, when the arm 51 drives the second sub-member 50 to rotate to the specific position relative to the first adjusting member 20 around the second shaft 55, the third engaging portion 24 and the fourth engaging portion 41 are engaged with each other. The relative rotation angle between the first engaging portion 12 and the second engaging portion 23 can be designed according the practical requirement, and the relative rotation angle between the third engaging portion 24 and the fourth engaging portion 41 can be designed according the practical requirement. Thus, it facilities to limit the range of the first specific angle and the ranged of the second specific angle. However, it is not an essential feature to limit the present disclosure, and not redundantly described herein. In the embodiment, the first adjusting member 20 further includes at least one limitation portion 26 disposed adjacent to the at least one inclined plane 25 to limit a rotated angle of the second sub-member 50 relative to the first adjusting member 20 around the second shaft 55. It facilitates the user to rotate the arm 51 to switch the operations between the adjustment of angle and the position at the specific position.
In the embodiment, when the arm 51 drives the second sub-member 50 to rotate around the second shaft 55 and misalign the above specific position, the at least one pushing portion 52 of the second sub-member 50 is shifted away from the at least one inclined plane 25 of the first adjusting member 20. Consequently, the eccentric cam 53 releases the inner wall of the ring portion 14 of the fixing member 10 and not in abutting with the ring portion 14. The first elastic component 15 drives the second engaging portion 23 of the first adjusting member 20 to move away the first engaging portion 12 of the fixing member 10. The second elastic component 45 drives the fourth engaging portion 41 of the first sub-member 40 to move away the third engaging portion 24 of the first adjusting member 20. In that way, the three-dimensional angular adjusting and positioning device 1a is set in the adjustable state, as shown in
On the other hand, as shown in
