Detailed Description
Various embodiments of the present invention will be described below with reference to the accompanying drawings. For the purpose of clarity, numerous implementation details are set forth in the following description. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, these implementation details are not necessary. In addition, some conventional structures and elements are shown in simplified schematic form in the drawings for the sake of simplifying the drawings; and repeated elements will likely be referred to using the same reference numerals.
Fig. 1 shows a schematic view of a pivoting mechanism 100 according to a first embodiment of the present invention, and for clearly showing and distinguishing elements, a second pivoting member 150 of the pivoting mechanism 100 in fig. 1 is indicated by dotted lines, and an elastic line 180 is indicated by oblique lines. Referring to fig. 1, the pivoting mechanism 100 includes a first pivoting member 130, a second pivoting member 150, and an elastic wire 180. The second pivoting member 150 is pivotally connected to the first pivoting member 130, and the elastic wire 180 includes an abutting region 183.
The first pivot member 130 includes Rong Xianbu, 138, 139, and the elastic wire 180 is positioned at Rong Xianbu 137, 138, 139. When the first pivoting member 130 and the second pivoting member 150 pivot relatively, the abutting area 183 abuts against the abutting engagement area 153 of the second pivoting member 150. Therefore, when the first pivoting member 130 and the second pivoting member 150 are pivoted relatively, the pivoting angle can be stopped (i.e. stopped, maintained) at any pivoting angle (i.e. rotation angle) or a specific pivoting angle according to requirements and designs, and the mechanism volume can be effectively reduced, the service life can be prolonged, and the assembly complexity, the components and the assembly cost can be reduced. According to another embodiment of the present invention (not shown), the second pivoting member includes a line-receiving portion, and the elastic line is located at Rong Xianbu. When the first pivoting piece and the second pivoting piece pivot relatively, the abutting area abuts against the abutting matching area of the first pivoting piece.
In detail, the elastic wire 180 may be a piano wire, a friction force is generated between the abutting region 183 and the second pivoting member 150 (the abutting region 183 slightly deforms and abuts against the abutting engagement region 153 of the second pivoting member 150), and the first pivoting member 130 and the second pivoting member 150 can stop relative pivoting at any pivoting angle. Therefore, the elastic wire 180 has an elastic force, and when the elastic wire abuts against the second pivoting member 150, the elastic wire is deformed due to the drop of the design assembling position (i.e. the abutting engagement region 153 protrudes from the assembling engagement region 157), and the elastic force is provided by the deformation and is applied to the second pivoting member 150, so that a friction force exists between the elastic wire 180 and the second pivoting member 150. Furthermore, the second pivoting member 150 can be stopped at any pivoting angle by the friction force between the abutting region 183 of the elastic wire 180 made of piano wire and the second pivoting member 150, i.e. an external force is required to be applied to make the first pivoting member 130 and the second pivoting member 150 pivot continuously. Further, the open and closed positions of the second pivoting member 150 can be limited, and the volume of the pivoting mechanism 100 can be reduced more effectively.
Specifically, the pivot mechanism 100 further includes a pivot pin 170, and the first pivot member 130 and the second pivot member 150 pivot relatively around the pivot pin 170. The first pin receiving portions 131 and 132 of the first pivoting member 130 include first pin holes 141 and 142, respectively, and the second pin receiving portion 151 of the second pivoting member 150 includes a second pin hole (not numbered). The pivot pin 170 is inserted into the first pin holes 141, 142 and the second pin hole. The wire-receiving portions 137, 138 and 139 of the first pivoting member 130 respectively include wire holes 147, 148 and 149, and the elastic wire 180 is inserted into the wire holes 147, 148 and 149. Furthermore, the number of the elastic wires 180 is one, and the pivoting mechanism 100 includes two sets of pivoting components through which the elastic wires 180 are disposed, the two sets of pivoting components being balanced with respect to the second pivoting member 150 and operating cooperatively. Each set of pivot components of pivot mechanism 100 includes first pin receiving portions 131, 132, first pin holes 141, 142, wire receiving portions 137, 138, 139, wire holes 147, 148, 149, second pin receiving portion 151, second pin hole, abutting engagement region 153, and abutting region 183 on elastic wire 180.
According to other embodiments of the present invention (not shown), the roller pin may be integrally formed with one of the first pivoting member and the second pivoting member. Or, the first pivoting member and the second pivoting member can be integrally formed, and the first pivoting member and the second pivoting member pivot relatively by changing the bending angle therebetween.
Fig. 2 shows a perspective view of a cover lifting device 200 according to a second embodiment of the present invention, fig. 3 shows an exploded view of the cover lifting device 200 according to the second embodiment of fig. 2, fig. 4 shows a top view of the cover lifting device 200 according to the second embodiment of fig. 2, and for clearly showing and distinguishing elements, a cover 250 of the cover lifting device 200 in fig. 2 and 4 is shown by a dotted line, and an elastic line 280 is shown by a diagonal line. Referring to fig. 2 to 4, the cover lifting device 200 includes a base 230, a cover 250, at least one pivot pin 270, and an elastic wire 280. The first pin receiving portions 231 and 232 of the base 230 respectively include first pin holes 241 and 242, the second pin receiving portion 251 of the cover 250 includes a second pin hole 261, the pivot pin 270 is disposed through the first pin holes 241 and 242 and the second pin hole 261, and the elastic wire 280 includes at least one abutting region 283.
The thread-containing portions 237, 238 and 239 of the base 230 respectively comprise thread holes 247, 248 and 249, and the elastic thread 280 is arranged in the thread holes 247, 248 and 249. When the base 230 and the cover 250 pivot relative to each other about the pivot pin 270, the abutting region 283 abuts against the abutting engagement region 253 of the cover 250. Therefore, when the base 230 and the cover 250 pivot relatively, the cover 200 of the present invention can be stopped at any or a specific pivot angle position according to the requirement and design, and the cover 200 has the advantages of easy assembly, high reliability and low cost, and has design flexibility to meet different design requirements under the condition of space limitation.
In the second embodiment, the abutting engagement region 253 and the assembling engagement region 257 are respectively different cam surfaces on the second pin receiving portion 251, and the abutting engagement region 253 protrudes from the assembling engagement region 257, that is, the outer diameter of the abutting engagement region 253 is larger than the outer diameter of the assembling engagement region 257. When the base 230 and the cover 250 are relatively located at any pivot angle, the abutting engagement region 253 abuts against the elastic wire 280, and a gap exists between the assembling engagement region 257 and the elastic wire 280, as shown in fig. 4. The wire hole 247 is closed (i.e., 360 degrees surrounds the elastic wire 280), and the wire holes 248 and 249 are non-closed buckles, and the abutting engagement region 253 is far from the closed wire hole 247 than the assembly engagement region 257 so as not to prevent the elastic wire 280 from being assembled in the wire hole 247. According to the embodiment of the invention, each of the first pin hole, the second pin hole and the wire holes can be closed or non-closed, the number of the wire containing part and the wire holes thereof can be increased or decreased according to requirements, and all the wire holes can be arranged in a straight line or arranged according to the bending shape of the elastic wire in cooperation with the shape that the elastic wire is a straight line or a bending line.
In detail, the base 230 may include wire holes 247, 248, 249, and when the base 230 and the cover 250 pivot relatively around the pivot pin 270, the abutting region 283 abuts against the cover 250. Therefore, the cover-lifting device 200 can be opened and closed more easily and smoothly, and the reliability of the cover-lifting device 200 can be improved. According to other embodiments of the present invention (not shown), the cover may include wire holes, and the elastic wires are inserted into the wire holes, so that the abutting region abuts against the base when the base and the cover pivot around the pivot pin relatively.
The elastic wire 280 can be a steel wire, and the abutting region 283 and the cover 250 have a friction force (generated by the abutting region 283 slightly deforming and abutting against the abutting engagement region 253 of the second pivoting member 250), and the base 230 and the cover 250 can stop pivoting relative to each other about the pivot pin 270 at any pivoting angle. Therefore, the cover 250 can be stopped at any pivot angle during the pivoting process, i.e. an external force is required to be applied to enable the base 230 and the cover 250 to continue to pivot relatively around the pivot pin 270, and the external force required by the use can be designed according to the structural shape of the abutting-against matching region 253 and the size of the wire diameter of the elastic wire 280, thereby more effectively reducing the components and assembly cost of the cover-lifting device 200.
Fig. 5 shows a rear view of the cover lifting device 200 according to the second embodiment of fig. 2, please refer to fig. 2 to 5, the number of the rotating shaft pins 270 and the abutting regions 283 of the second embodiment is two, and the two rotating shaft pins 270 and the two abutting regions 283 are both disposed in a balanced manner with respect to the cover 250. Therefore, the elastic wire 280 in the cover lifting device 200 of the present invention has design elasticity. Specifically, the number of the elastic wires 280 is one, and the shape of the elastic wires 280 is bent and symmetrical to the central plane CP of the cover lifting device 200. The cover lifting device 200 includes two sets of pivot elements through which the elastic wires 280 are passed, which are also disposed in balance with respect to the central plane CP and operate cooperatively. The two sets of pivot assemblies of the cover-lifting device 200 are substantially the same as the two sets of pivot assemblies of the pivot mechanism 100 according to the first embodiment of the invention, and the base 230 and the cover 250 of the cover-lifting device 200 correspond to the first pivot member 130 and the second pivot member 150 of the pivot mechanism 100, respectively. Each set of pivot components of the cover lifting device 200 includes a first pin receiving portion 231, 232, a first pin hole 241, 242, a wire receiving portion 237, 238, 239, a wire hole 247, 248, 249, a second pin receiving portion 251, a second pin hole 261, an abutting engagement region 253, and an abutting region 283. According to another embodiment of the present invention (not shown), the number of the pivoting assemblies in the pivoting mechanism or the cover lifting device may be one or more than three, one elastic wire may be inserted through the plurality of pivoting assemblies, or a plurality of elastic wires may be respectively inserted through the plurality of pivoting assemblies.
The abutment region 283 of the elastic wire 280 may be adjacent to and parallel to the roller pin 270. Therefore, the cover-lifting device 200 can stop at any pivot angle during the pivoting process without increasing the additional volume, and is helpful to improve the smoothness during the pivoting process and reduce the assembly complexity and the assembly time. Specifically, the elastic wires 280 made of steel wires are inserted into the wire holes 247, 248, 249 of the base 230, thereby completing the assembly of the flip device 200 according to the second embodiment.
Fig. 6 is a cross-sectional view of the cover lifting device 200 along the sectional line 6-6 in fig. 5, fig. 6 is a schematic view illustrating the maximum opening state of the cover lifting device 200, fig. 7 is a schematic view illustrating the opening state (i.e., the non-maximum opening state) of the cover lifting device 200 in fig. 6, and fig. 8 is a schematic view illustrating the closing state of the cover lifting device 200 in fig. 6. Referring to fig. 5 to 8, the abutting engagement region 253 of the cover 250 may include an opening engaging unit 254 and a closing engaging unit 255. When the base 230 and the cover 250 are in the maximum opening state, the abutting region 283 of the elastic wire 280 is engaged with the opening engaging unit 254. When the base 230 and the cover 250 are in the closed state, the abutting region 283 of the elastic wire 280 is engaged with the closing engaging unit 255. Therefore, the base 230 and the cover 250 can be stably maintained in the maximum open state and the closed state.
Referring to fig. 6, which is a schematic view illustrating a maximum opening state of the cover lifting device 200, the opening engaging unit 254 may be a groove, and when the base 230 and the cover 250 are in the maximum opening state, a resultant force direction FM applied by the elastic wire 280 to the opening engaging unit 254 substantially passes through the axial center 276 of the pivot pin 270, as shown in fig. 6. Therefore, the shape design of the opening latch unit 254 is helpful to improve the stability and reliability of the maximum opening state, and the cover 250 can be accommodated and abutted against the elastic wire 280 only by the opening latch unit 254 thereon and stably maintained in the maximum opening state without the support of the cover 250 by the base 230.
Referring to fig. 7, which is a schematic view of the open state of the cover lifting device 200, the cover lifting device 200 can stop the cover 250 at any pivot angle position by using the friction force between the abutting region 283 of the elastic wire 280 made of piano wire and the abutting engagement region 253 of the cover 250 and the elastic force generated by slight deformation of the abutting region 283.
Referring to fig. 8, which is a schematic diagram illustrating a closed state of the lid lifting device 200, the closing engaging unit 255 may be a groove, and when the base 230 and the lid 250 are in the closed state, the resultant force direction FC of the elastic wire 280 applied to the closing engaging unit 255 substantially passes through a lower portion of the axis 276 of the hinge pin 270, i.e., the resultant force direction FC is farther away from the lid 250 than a connection direction L1 of the axis 276 of the hinge pin 270 than an axis (not numbered) of the elastic wire 280, i.e., the resultant force direction FC is downward than the connection direction L1 in fig. 8. Accordingly, the shape design of the closing engagement unit 255 contributes to improving the stability and reliability of the closed state.
Fig. 9 is a diagram showing the comparison of the characteristics of the second embodiment of the cover lifting device 200 and the prior art cover lifting devices 80 and 90, wherein the pivot pins of the prior art cover lifting devices 80 and 90 are spiral spring pins, the wire diameter of the spring pin of the prior art cover lifting device 80 is 0.03mm, the wire diameter of the spring pin of the prior art cover lifting device 90 is 0.12mm, and no elastic wire is provided for the cover lifting devices 80 and 90. The pivotal opening and closing of the cover lifting devices 80 and 90 of the prior art can stop the cover body at any angle, but the stopping effect of the cover body will gradually disappear (i.e. the abutting force approaches zero) as the opening and closing times are increased, and the components and assembly of the cover lifting devices 80 and 90 of the prior art are complex, the assembly time is long, and the cost is high. The cover-lifting device 200 according to the second embodiment of the present invention has a substantially longer service life and is less prone to be lost due to the elastic force provided by the elastic wire 280 made of steel wire, i.e. has a better reliability.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
