Description of the Invention: [Technical Field of the Invention] The present invention relates to a hinge, and more particularly to a dual axial hinge. [Prior Art] At present, in order to allow users to use electronic devices without being restrained by the venue, many kinds of portable electronic devices have been developed. Among them, for portable electronic devices used with screens, such as notebook computers, personal digital assistants (PDAs), digital cameras, mobile phones, etc., in the maintenance of the device is light and small, but also to take into account the larger display area and more functions. Under the conventional device, there is a design method using a flip cover. The electronic device designed by the cover usually separates the body from the screen and is connected by a hinge to provide a function of opening the screen and flipping the screen so that the screen can be rotated in different axial directions and at different angles with respect to the body. In order to provide the above functions, many different hubs have also been proposed in the prior art. For example, please refer to Fig. 1, which is a perspective view of a conventional hinge. As shown in FIG. 1 , the conventional hinge system includes: a fixed frame 10 , a horizontal rotating frame 20 , a vertical shaft assembly 30 , a vertical rotating frame assembly 40 , a horizontal limiting component , a horizontal positioning component and A vertical limit component. In such a button, the holder 10 is used to fix the screen on which the electronic device is disposed, and the vertical frame assembly 40 can be used to connect to the body of the electronic device. The vertical shaft assembly 30 is disposed on the horizontal rotating frame 20 and the fixed frame 10, and includes a vertical shaft 31 and a baffle 32. The vertical shaft 31 rotatably penetrates the vertical pivot on the substrate 21 of the horizontal rotating frame 20. The hole 211 is threaded through the through hole 11 of the fixing frame 10 in a non-rotatable but slidable manner. The section of the vertical shaft 31 adjacent to the bottom end has a non-circular cross section to match the non-circular cross section of the through hole 11 of the fixing frame 10. The vertical shaft 31 is not movable relative to the fixed frame 10 201240578, and the baffle 32 is fixed to the bottom end of the vertical shaft 31. The horizontal limiting component includes a limiting block 231 and a limiting ring 33. The limiting block 231 is formed on the inner side wall of the cavity 23 of the substrate 21; the limiting ring 33 is radially from the top of the vertical axis 31. The outer protruding protrusion 33 is formed with a limiting block 331 which can be engaged with the limiting block 231 of the substrate 21, thereby restricting the horizontal rotating frame 20 from rotating further relative to the vertical axis 31, so as to avoid the electronic device. The circuit between the body and the screen is kinked and broken. However, since the conventional frame device utilizes the latch of the limiting block 231 and the limiting block 331 to limit the rotation of the horizontal rotating frame 20 relative to the fixed frame 10 and the vertical axis 31, the body and the screen of the electronic device are used. The inter-route may pass through the path of the stop block 331 to be worn, which may be worn when the limit block 331 is rotated, causing the electronic device to malfunction. SUMMARY OF THE INVENTION In view of the above, in order to overcome the problems of the conventional device, it is an object of the present invention to provide a biaxial hinge that avoids damage to a line causing an electronic device provided with the above biaxial hinge.

The present invention allows the line to pass through the hollow main shaft member and the third through hole without being worn by placing the stopper projection for limiting the rotation of the support frame on the cam. [Embodiment] Figs. 2 to 6 illustrate a biaxial hub of the present invention. Fig. 2 is a perspective exploded view of the biaxial hub of the present invention. As shown in Fig. 2, the branch of the present invention comprises: an n-type support base (10), and the door type is formed along the first portion and is disposed on the first through-hole: 2 on '. The support portion 120, no includes: a first protrusion ln, a middle support of a rotary support portion support base (10), and the second attachment to the door type support wheel 111 has a money-sliding convex 201240578 block 111A And a first stop bump has a plurality of second sliding protrusions 112a and a first cam 112, and has a support frame 113 coupled to the second second stop protrusion 112B; the wheel 112 rotates synchronously; The spacers 1212 and the second protrusions are configured to cause the first cam 111 and the second-first elastic member 115, a hollow main shaft member 116 to be protruded and protruded from each other; and the spacer 114 The support frame 113, the first elastic member 115, the cam 111, and the first through hole 〇 〇 factory cam 112, and the first type support base 100. In addition, the above flute _ / can be fixedly fixed to the door-third cam 12 by pivotal connection; the upper support portion 120 includes: 1 上述 of the second through hole 102 (7); a fourth 1 door: 支 = seat Setting: the upper cooking 122 of the n-type supporting base 100 is inserted through the second elastic member 123 for abutting the above-mentioned second and second cams 122 to each other; The elastic member 123 and the fourth protrusion sequentially pass through the third cam 12 and pass through the second perforated handle = the above-mentioned door-type support base 100 and the fourth cam 12. Further, the side shaft member 124 can be described as being the same as the above-mentioned configuration. Further, the first sliding projection 111A is upper than the axial center of a cam 112 of the first cam in, respectively. a first-to-radial distance = upper sliding, the first stopping protrusion 111B and the upper rail and the axis of the first cam U1 are: a second radial distance from the axis of the rim rim 2 - a convex movement, the first radial distance may be greater than or smaller; ^ the track is slid away. The radial distance of the second brother is referred to the third map and the third map, respectively, which indicate that the aligning distance is greater than the second diameter A perspective view of the first cam 1 to 11 and 201240578 to the second cam 112. As shown in FIG. 3B, the first cam 111 has a through hole 111c formed along the axial direction thereof, and surrounds a plurality of first sliding protrusions 111A and a first stopping protrusion 111B formed by the through holes (1) and (3). The first sliding protrusions 1UA are slid on a sliding track on the outer side of the cam surface of the first cam (1). And the first stopping protrusion 111B is attached to the cam surface of the first cam lu Sliding on the moving rail. As shown in FIG. 3A, the second cam ι 2 has a through hole 112C formed along its axis and direction, and a plurality of second portions formed around the through hole ii2c. a sliding protrusion 112A and a second stopping protrusion 112B. The second sliding protrusion U2A slides on a sliding path on the outer side of the cam surface of the second cam 112, and the second stopping protrusion 112B Sliding on a stop of the inner side of the cam surface of the second cam 112. When the first cam m and the second cam 112 are assembled to the biaxial hinge of the present invention, the axes thereof coincide The first sliding protrusion iiiA and the second sliding protrusion 112A are opposite to each other, and the first stopping protrusion 111 Β and the second stopping protrusion n2B are opposite to each other. The first cam ηι and the second The cams 112 are abutted against each other by the pressure of the first elastic member Π5. Although the support frame 113 is swayed relative to the door-type support base 1, the first sliding protrusion 111A and the second sliding protrusion are , 112A is sliding along it A slope is formed on both sides of the track direction, and even if the first sliding protrusion 1UA abuts against the second sliding protrusion 112A, the distance of the first elastic member 115 is compressed by the first elastic member 115. In the allowable range, when the first cam 1Π is in contact with the second cam 112, the first sliding protrusion 1B is not provided as long as the first stopping protrusion 111B is not in contact with the second 201240578 moving protrusion 112B. The second sliding protrusion 112A can be slid against the second sliding protrusion 112A. When the first stopping protrusion 111B contacts the second stopping protrusion 112B, due to the edge of the first stopping protrusion 1UB and the above The edges of the second stopper projection 112B are not formed with a slope surface, so that the two cams 111 and the second cam 112 cannot continue to oppose each other at the edges where the two stopper projections are in contact with each other. Turn. Specifically, it may be provided that the position of the first cam lu is sliding, the cam surface at the track is aligned with the cam surface at the stop, and the second cam 112 is sliding. The cam surface at the road is aligned with the cam surface at the stop rail, that is, the cam in which the first sliding projection 111A and the first stopper projection 1UB are provided at the same height position The surface and the second sliding projection 112A and the second stopper projection U2B are provided on the cam surface at the same position. In this case, the sum of the height of the first stop protrusion 1UB and the height of the second stop protrusion 112B is greater than the height of the first sliding, the protrusion 111A is greater than the second sliding protrusion. The degree of U2A is such that when the first sliding protrusion U1A and the second moving protrusion 112A are in the up-and-down state, a difference between the two causes the first stopping protrusion 1UB The second stopper projections 112B are just shifted up and down and cannot abut each other. In this way, it can be ensured that when the first stop projection 111B is close to the first stop projection 112B, the first cam U1 and the second cam cannot be relayed at the edge of the contact. In addition, when the first stopping protrusion 111B and the first stopping protrusion 112B are brought close to each other, the first sliding protrusion 111A and the second sliding protrusion u2a are also exactly matched. The gap position of the container 201240578 (the recess between the bump and the bump), so that the first cam 111 and the second cam 112 are tightly engaged to make the first sliding bump 111A and the second sliding A height difference between the bumps 112A is small (if the two are completely combined, the height difference is regarded as 〇). In this way, the first stopper projection U1B and the second stopper projection 112B can be abutted against each other at the edge of the contact, so that the first cam 111 and the second cam 112 cannot continue to rotate relative to each other. In the case of the first sliding block 111B, the convex top surface of the first stopping protrusion 111B may be raised, and the convex top surface of the first sliding protrusion 111A may be aligned, and the convex top surface of the first stopping protrusion 111B may be Provided is flush with the convex top surface of the second sliding bump 111A.

Furthermore, it also contributes to the above-mentioned first rotation cam m (four) joint structure is more firm and precise, and does not 匕 = 201240578, and, in the case, please refer to FIG. 4A and FIG. 4B, respectively, when the first radial direction is A perspective view of the first cam 111 and the second cam 112 when the distance is less than the second radial distance. As shown in FIG. 4B, the first cam U1 has a through hole 111c formed along the axial direction thereof, and a plurality of first sliding protrusions 111A and a first stopping protrusion mB formed around the through hole. . The first sliding projection 111A slides on a sliding path on the inner side of the cam surface of the first cam in, and the first stopping projection 111B is on the outer side of the cam surface of the first cam ln. Slide on a stop rail. Similarly, as shown in FIG. 4A, the second cam 112 has a through hole U2C formed along the axial direction thereof, and a plurality of second sliding protrusions U2A and a plurality formed around the through hole 112C. Two stop bumps 112B. The second sliding protrusion 112 is slid on a sliding path on the inner side of the cam surface of the second cam 112, and the second stopping protrusion 112B is on the outer side of the cam surface of the second cam 112. A stop on the road is slipping. When the first cam 111 and the second cam 112 are assembled to the biaxial hinge of the present invention, the axes thereof are coincident such that the second sliding protrusion 111A and the second sliding protrusion U2A are opposite to each other, and The first stopper projection mB and the second stopper projection 112B are opposed to each other. Regardless of the difference in the relative positions where the sliding projections and the stopper projections are formed, and the height difference (position on the same plane) between the slide rail and the stopper rail, the first cam in the present embodiment and The operation of the second cam is similar to that of the above-described sliding projection and the stopper, and its limitation is similar to the embodiment described above in connection with FIGS. 3A and 3B, and thus the description thereof will not be repeated. In addition, according to an embodiment of the invention, the length of the first stop projection 1UB and the second stop projection 1123 on the circumference are respectively one eighth of the circumferential length of 12 201240578. Thus, the angle at which the first cam U1 and the second cam 112 are relatively rotatable is 270 degrees. If the length of the first stopper projection 111B and the second stopper projection 112B on the circumference are respectively a quarter of the circumferential length, the angle of the relative rotation can be 180 degrees. Next, according to Figs. 3A and 3B, the lengths of the two first sliding projections 111A on the circumference are respectively one quarter and one eighth of the circumferential length. The lengths of the two second sliding projections U2A on the circumference are one quarter and one eighth of the circumferential length, respectively. Thus, the first 111 and the second cam 112 snap into engagement when rotated to a relative twist and 27 degrees. According to Figures 4A and 4B, the lengths of the four first sliding projections 1UA on the circumference are respectively one quarter of the circumferential length. The lengths of the four first sliding projections 112A on the circumference are respectively One quarter of the length of the circumference. Thus, the first cam 1U and the second cam 112 can be snap-fitted when rotated to 0, 90, 180, and 270 degrees. Thereby, the first cam can be provided. The positional action of the m and the second cam 112 at a specific angle when the phase is rotated. Of course, the length of the present invention and the non-movable bump and the sliding projection on the _ can be adjusted as needed. The operation mode of the fourth cam 122 is similar to that of the first cam ln and the second cam 112. However, the second cam 122 is not formed on the upper 121 and the fourth cam 122, and the second rotating branch is restricted. The manner of rotation of the π-axis member 124 of the floor portion utilizes a limit Τ 125 having a non-circular (e.g., square) perforation formed therein to be fixedly coupled to the side shaft member 124, ί stop member 125 Cannot be relative to the above-mentioned side shaft member 124 = I in the above (10) The circumference of the second money pen 2 of the base 100 is turned upwards. 13 201240578-position flange 131 'When the side shaft member 124 is rotated a year, and the limit stop member 125 is on the side = movement, the above limit is The position flange 131 is dry, and the member 124 is rotated-angled to be within a predetermined range = wrong so that the upper rotation member (3) is described below to assemble the second rotation branch. First, the manner of the third cam 丨 20 described above is shown. In the second hole 102 of the second through hole 102, the third cam 12丨T is simultaneously formed into a fixed block shape, so that the opening formed by the fixing block 132 is not roundly accommodated in the third portion. The cam 121. ~ The work space can be fixed at the end. Please refer to Fig. 2, the section of the present Mingu Gu, above the fourth 24th cam, to rotate the fourth cam (2) benefit side shaft member 124. Then, As described above, the third cam 121 and the fourth cam member 123 are placed on the side of the side reducer 124. Finally, the 'e-ring} 126 uses the side shaft member as J 'locking member (for example, the support base 100' can complete this two The assembly of the two rotating support portions (side shaft portions), and the axial hinge, can avoid the use of the double limit stop member to merge into the cam. In addition, the use of the cam surface: two H = road is subject to == in the range of wheel rotation == As mentioned above, only the rabbits limit the implementation of the invention, and cannot be changed or replaced by the contents of the specification; 2 The configuration is within the scope of the present invention covering 14 201240578.
