Description of the invention (1), background of the invention (please read the precautions on the back before filling out this page) Many electronic devices need to be equipped with the cover of the hinge. These hinges often require friction or non-return claws to control the positioning of the cover. In several cases, it was considered necessary to have both friction and one or two check jaws. The smaller the electronics themselves, the smaller the hinges. Most friction hinges in the previous case produced a certain amount of friction as a function of angle. A few of the disclosed friction hinges allow the torque to vary with angle, although for smaller electronic devices, they tend to be too large. Another troublesome characteristic of the former hinge is that the friction and / or check force generated in the assembly is not symmetrically arranged around the axis of the hinge. As a result of this asymmetry, during the rotation of the hinge, a force will be generated in the axis line. This force is not good because it is an extra source of friction that is difficult to control. In addition, this bearing friction causes bearing deterioration, wear, and first rotation. The invention provides a small cylindrical hinge or a pivot pin, the shape of which can produce various extrusions with torque contrast angles. The required extrusion of the torque control angle is achieved by the shape of the hinge shaft and the hinge spring plate. With or without friction damping torque at other angles, it can achieve a check at one or more angular positions. In this case, the friction of the hinge was generated symmetrically around the axis of the hinge, eliminating the problems related to the asymmetric structure. Printed by Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics, Brief Description of the Invention A preferred embodiment of the hinge of the present invention has a generally cylindrical outer shape to facilitate easy installation on various host devices using the hinge. The casing is divided into two cylindrical sections that are axially adjacent and held together, but can be rotated relative to each other. In order to prevent the outer shell of the hinge from rotating within its host equipment part, the outer surface of the shell section of the hinge must have characteristics, such as axial grooves or protruding protrusions. Paper standards are applicable to national standards (CNS) A4 specifications { 210X297 mm) A7 B7__ V. Description of the invention (2) Fate, in order to combine the matching characteristics in the host device. The preferred embodiment of this case has a groove on the outer surface to estimate that there is the least available space in the host device. The shaft is pressed into a section of the hinge housing, then rotates and extends into the other section of the housing, which contains a spring section and is arranged symmetrically around the broom. The spring plate contacts the shaft during rotation, causing friction and / or non-return forces determined by the shape of the shaft and plate. Since the diameter of the hinge is usually quite small, a large amount of surface stress will be encountered between the shaft and the surface of the spring plate to generate the required torque. Another specific example is a grinding plate on each side of the shaft, which is the first spring plate. It is therefore an object of the present invention to provide a small-sized rotating friction and / or non-return device. A secondary object of the present invention is to provide a hinge member which needs to have an extremely simple but firm interface with a host device. Another object of the present invention is to provide a rotary friction and / or non-return hinge member whose torque / non-return characteristics can be matched with the special requirements of the host device using the hinge member. Employees of the Central Standards Bureau of the Ministry of Economic Affairs cancel the cooperative seal (please read the precautions on the back before filling out this page). Another object of the present invention is to provide a pivot hinge in bismuth, with a symmetrical structure on the M axis, so the rotation of the hinge In radial bearings, there is essentially no net radial force that occurs internally. It is a further object of the present invention to provide a long-life rotating frictional hinge whose operating characteristics can be maintained substantially constant. Finally, another object of the present invention is to provide a rotary friction hinge, which has a simple structure, is composed of two pieces, and is easy to combine. The advantages and other advantages of the present invention can be understood from the following. 2 —1 This paper is applicable to China® National Standard Cars (CNS> Α4 specification (210 × 297 mm > 4453 39 a? .-- B7 —.

In Fig. 1, the preferred specific example of the combined hinge has a general cylindrical shape. The base 1 and the cover 3 have the above-mentioned axial grooves, so that each section can be rotated. Installed in one piece of host equipment. Other shapes are also effective, for example, the shell and the base can form a square cross-section to prevent installation holes; rotation in the hole. Figure 2 shows the pivoting method of the base 1 and the shell 3, Make sure that it rotates coaxially. The shaft 5 has a roller pattern and is pressed into the axial hole of the base 1. The other end of the shaft 5 has a lock ring groove. The lock ring 7 holds the assembly together. -3-Paper The scale is applicable to the Chinese National Standards (CNS) Λ4 specification (210 × 297 mm) 4 45 3 3 9 A7 _____B7_ V. Description of the invention (4) Two sets of plates 9 can be seen in the circle 3 and set into the grooves 11 on the inner surface of the cover 3. Each component is located on each side of the shaft 5, see also 圚 4. There are single plates or a number of plates on each side, depending on the level of stress that occurs when the shaft rotates. The plate 9, the groove 11 and the shaft 5 Size so that when the plate is inserted into the assembly, it can resist the shaft. The force is based on the requirements of the equipment; if the shaft 5 has a circular cross section, when the shaft 5 rotates on the plate 9 j. '·' When moving, there will be uniform frictional resistance. The shaft in Figure 4 has a symmetrical but non-circular cross-sectional shape. When the shaft 5 rotates relative to the cover 3 and the plate 9, the torque is required. The plate 9 The deflection will vary depending on the shape of the shaft 5. Changing the shape of the shaft, the required torque shape can be adapted to the needs of the staff. Page) The major advantage of the present invention is that the friction force is symmetrical around the axis of the hinge, so when the shaft 5 protrudes from the casing, between the shaft 5 and the casing 3, or in the rotating joint between the base 1 and the casing 3 There is no net side load. This point is particularly important in the specific example shown in Figure 5. Its structure is similar to the previous specific example, except that the axis 13 is generally smooth and symmetrical with two separate flat surfaces 17. It is set around the axis of the axis When the shaft 13 is rotated from the position shown in FIG. 6 to the position shown in FIG. 6, the plate 15 is bent, and a restoring torque is generated, so that the shaft 13 is returned to its initial setting. When the bent portion 19 of the shaft 13 is in contact with the plate 5, the restoring torque disappears, leaving only the friction torque to resist rotation in either direction. It can be known from the foregoing that the shape of the 圚 5 of the present invention provides a rotary joint hinge with two check positions. Obviously, if the shaft is square, the hinge has four check positions. The smaller the outer diameter, the greater the force required to produce any given torque. Under high load conditions, such as 圚 5 and 圚 6, the shape of the shaft will have a small radius of curvature at the edges, which will cause large surface stress on the plate. Since the maximum buckling occurs when the local concrete surface stress is greatest, stress failures limit the torque achieved. -4-This paper size is in accordance with Chinese National Standard (CNS) A4 specifications (210 > < 297 Gongchu :) Α7 Β7 ϊ 445339 5. Invention Description (5) (Please read the precautions on the back before filling this page) This This condition can be alleviated by increasing the radius of curvature of the shaft angle. The hinge shown in circle 7 is similar to that shown in Figs. 5 and 6, but the shaft 21 is rotated, so the corners will touch the plate. In the hinge member of Fig. 7, each of the two sets of plates is composed of a thinner plate 23 contacting the shaft 21 on the inside and a thicker plate 25 on the outside of the thinner plate 23. Due to the thinness, the buckling stress on the surface material of the inner plate 23 is less than that when the plate is thicker. 1. Since the stress failure depends on the total stress, reducing the buckling stress can reduce the effect of surface stress caused by contact with the shaft. The thicker outer plate 25 results in less surface stress, so that it can withstand greater buckling stress. FIG. 8 shows another specific example of the present invention, which has the characteristics of a groove, a plate, and a shaft shaped like a triangle. The three recesses in the cover 29 contain three plates 31 surrounding the shaft 33. In the illustrated specific example, the shaft 33 has three flat surfaces corresponding to three sets of plates. This configuration guarantees a 120-degree check position. As before, if the shaft section is smooth, the device has pure friction torque. Obviously, many other shaft configurations can be used to provide many combinations of frictional twist and non-return, and the configurations shown so far are all symmetrical about the axis of the shaft. However, there are many asymmetrical shapes. Although asymmetrical axis configurations can produce undesirable side loads, some applications can tolerate a small amount of side loads in order to obtain the benefits of a special asymmetrical shape. Figure 9 shows the shape of another asymmetrical axis. The shaft 35 has flat surfaces 37 at any angle relative to each other. When it contacts one plate 39, it generates a check force, and it is in contact with the other plate. When in contact, it has frictional torque. The circle 10 represents another modification of the present invention, in which the shape of the shaft 41 is an arc shape and the characteristics of the matching belt 43 are. This model has a strong non-return at the position shown in Figure 10. When the shaft rotates, the friction torque is large enough to make the band -5-this paper size is applicable to China National Standard (CNS) A4 size (210X297 mm) ) / J 4 5 3 3 9 A7 B7 V. Description of the invention (1) The non-return characteristic contacts the outer diameter of the shaft. All the specific examples of the present invention are advantageous from the viewpoint of using multiple plates to limit the buckling stress of each plate. When a thin plate is used, the inner plate in each stack has the advantageous effect of reducing the total stress in the plate. The total Gein stress is the sum of buckling and Hertz or surface stress. 'Because these inner plates must have surface gland i- · forces in contact with the shaft, it is better to make the plates thin to minimize their buckling stress.
