The common feature of the folding electronic product is that it has a (10) (four) · start-up display and a body, and the folding or opening action is achieved by a hinge. In the prior art, there is a concave cam knot that provides an automatic closing function on the hinge to achieve the compacting effect of the folding electronic product without Latch. For example, in the Republic of China new patent] VI254878 "the silver button with positioning function" and the applicant, China, the new national patent gambling 54 Β "has the _ 阖 Wei Zhizhi" and other patents, φ is the use of such concave cam design . • . ~ The Chinese patent in the Republic of China, the new patent M295419 "with automatic closing function. The ugly device" case, also revealed the structure of the concave wheel designed on the vertical frame of the base in order to achieve a smaller size of the entire hub. The advantages. However, in these front needles, the design of the maximum lining angle limit function has not been revealed. In the case of Shen Qingren's new patent of the Republic of China (10), such as the 52 "single-shoulder double-point pivoting device", the previous technical shot also mentioned that "the blocking point is formed on the frame of the rotating shaft to form a 3". M366874 - The stop 'and the 'shaft' - the peripheral edge of the periphery - the fan secret element, using the limit piece to rotate with the shaft, when the fan piece resists the load block on the frame, that is, the shaft is restricted The angle of rotation 'and thus prevents over-opening", however, the recessed cam in which the disclosed design structure achieves the automatic closing function is still a separate structure, and the structure of the recessed wheel design on the carrier is not disclosed. • Due to this maximum opening angle _When Wei is formed on the frame, the flat-type red bearing directly rushes out of the protruding (four) stop block, which will require a lot of pressure, which is also easy to make Φ Cheng Cheng The valley of the frame itself is easily destroyed, affecting the service life of the entire pivotal device and needs to be improved. [New content]. For this reason, this creation provides an automatic closing of a vertical frame with a concave wheel and a stop block. The hinge 'mainly forms at least two grooves formed by the grooves in the shaft portion of the vertical wire frame through the side holes: a concave portion formed by the grooves, and wherein the groove is stamped toward the other side to form a stop for the dog. Piece. The groove means cooperates with the lug means on the positioning cam on the shaft portion to form a self-healing; the wire block forms a sector with the outer edge of the shaft end portion and the crotch portion to form a maximum opening angle limiting function. 'This creation is due to the fact that the concave and stop blocks of the automatic closing function are formed on the vertical support frame', which will make the size of the entire pivoting device smaller, and provide a good compaction for the assembly of small notebook computers. condition. In addition, this creation will be finer than the shot-concave _, which will greatly reduce the forming force of the stop block, and reduce the damage caused by the forming of the vertical frame due to the formation of the bumper block. better. 4 M366874 The following is a detailed description of the structure and use of the creation according to the embodiment shown in the figure. [Embodiment] Referring to the first to third circles, the present invention provides an automatic closing pivoting device 1 having a vertical receiving frame with a concave wheel and a stop block function, which is disposed in a folding electronic product. No screen and Benedict (® wire). The main structure is composed of a button, a baffle 12, a shaft 13, a positioning cam m, an elastic component i 5 and a fixing device 16. The base 1 1 has a " horizontal negative film 1 1 1 and a vertical carrier 1 1 2 . The horizontal film 1 1 1 S1 is connected to the body of the folded electronic product, for example, a through hole 1 1 8 is formed in the horizontal film, and the body is closed by screws or rivets through the through holes i i 8 . The vertical frame 1 12 has a round hole! ! 3, and in the vertical bearing wi 2_ side η 4 around the circular hole 1 1 3 to form a groove device ii 5 i 5 b formed by the groove device 'and in the groove ii 5 a inward vertical frame 丄i 2 other side 丄丄 = pressure to form a protruding stop block 1 1γ, which can be matched with the seventh figure. The truss 1 2 is connected to the display of the folded electronic product, and is connected to the side of the display glory. The rotating shaft 13 has a connecting portion i 3 与 connected to the branching member 12, and passes through a non-circular shaft portion 13 2 of the circular hole 113 in the vertical bracket 112 of the base 11 . An enlarged portion 13 3 is formed at the end of the shaft portion 1 3 2 , and a sector 134 is formed on the outer edge of the enlarged portion 13 3 , and the sector block 134 forms a maximum opening angle limit with the stopper 1 17 . 5 M366874 Month B ° Positioning The protrusion m 4 has a non-circular aperture 4 through which the shaft portion i 3 2 passes, and two protrusions i 4 3 a and 4 3b are formed on the side i 4 2 of the vertical bracket 1 i 2 (10) The embossing device is configured, and the bulging device cooperates with the groove device to form an automatic closing function, which can be seen in the second A drawing. The miscellaneous component 15 is placed on the shaft and the 3 2 cut provides axial force. The elastic member 15 is composed of a plurality of elastic pieces 151. The fixing device 16 is fixed to the front end of the shaft portion 132, and the elastic member 丄5, the positioning cam 14, and the vertical frame 丄12 are sequentially assembled to the shaft portion 132. In addition, referring to the fourth to sixth figures, the creative branch building 2 is centered on the pivoting machine 3 and is opened at a different angle from the base 11. As shown in the fourth figure, the support W 2 and the base ii are at a closed angle. At this time, the two projections i 4 3 4 3 b of the positioning cam 14 are trapped due to the axial force provided by the elastic component i 5 . In the vertical support ii 2 on the _ a groove 丄 i 5 5 5, the lug device is engaged with the concave Wei, so that the hinge produces an automatic closing function when the angle is closed. > See the fifth figure' § Support 4 1 2 with the shaft 1 3 as the center, relative to the base 1 1 and open to the angle (as in the fifth figure is about the vertical angle), due to the non-circular positioning cam 丄4 ^/ Hole 1 4 1 is traversed by the (4) shaft portion 1 3 2 and will rotate with the same direction, so that the two bumps 14 3 a and 14 3 b will have two grooves a 15a & 115b outside, and on the side 114 slides the pawl' and presses the elastic component 丨5 in the axial direction due to the positioning cam i 4 relative to the vertical frame 丨i 2 (4), so that the support frame i 2 can be lowered by the base worker 6 M366874 • Positioned at any opening angle. Referring to the sixth figure, when the truss i 2 is rotated to the maximum position with respect to the pivoting machine 3, the sector i 3 4 on the rotating shaft i 3 is in the radial direction. Turn over the stop to limit the maximum opening angle of the support frame ^ relative to the base ^ to prevent over-opening. - This creation is formed by the concave wheel and the collision block that will automatically close the function. It will make the volume of the whole pivoting device 1 smaller, and for the small pen, the assembly of the electric type has provided a good tightening condition. In the fiber, the creation of the stop block 117 is formed in the groove In ii 5 a, the forming punching force of the stop block 1 i 7 is small, and the Wei of the vertical frame worker 2 due to the stop block is reduced, so that the _ lion makes the life better.
