Description

M442007 V. New description: [New technology field] [0001] This author is about a shaft structure for electronic objects; in particular, it refers to a shaft positioning structure, which uses the diameter of the shaft to change and the frictional resistance of the elastic device. The positioning function improves the wear and deformation stress of the conventional positioning component, and the novelty of obtaining assembly and the like. [Prior Art] Φ [0002] A revolving shaft (or pivot) that can be reciprocally rotated by an external force is applied to an electronic object such as a mobile phone, a notebook computer, a driving recorder, a digital video camera, etc. It is a well-known technique that the cover or display screen can be rotated to have an opening and closing function. For example, Taiwan No. 98225048 "Multi-stop shaft structure", No. 9821 1 263 "Protection of the shaft structure for providing torque with a flange", and Patent No. 961 09664 "Pivot with multi-friction interface" Etc., a typical embodiment of a combination of a rotating shaft and a positioning assembly (or positioning module) is provided. φ A subject of operation, motion and structural design in relation to the above-described embodiments is that they are provided with positioning flanges, pockets or embossments on opposite planes of a plurality of spacers, elastic sheets or elastic members, friction plates or related components. The fitting structure of the positioning portion causes the rotating shaft to form a positioning function when the flange is rotated to the position of the recess in the rotating operation. However, when they are applied to an electronic product, after a period of operation of the flange, the recess or the concave-convex positioning portion disposed on the opposite mating plane, the wear is often caused by the rigid contact, so that the positioning effect becomes not ideal. As known to those skilled in the art, the conventional technique applies 10121220^Single number deletion 1 Page 3 / Total 20 page 1012039224-0 M442007 Combination of multiple gaskets and friction months, and with elastic rings or springs Energy accumulation and release to achieve the rotation and positioning of the shaft or frame shaft assembly; its overall structural design and assembly fit are complex, and the assembly configuration length becomes very long in the axial direction, affecting and limiting the shaft and electronic objects. Configuration space.

Another subject related to the assembly of the rotating shaft and the positioning assembly is that the above-described elastic clamping action or the force adjustment of the frictional resistance is obtained by operating the locking force of the nut. If the gasket is too tight, the shaft (or the cover, display screen) will not achieve the desired positioning effect; if the gasket is too tight, the gasket often produces stress and deformation. And after the use of the rotating shaft, the components are particularly prone to wear and tear, and the rotating shaft is unstable or loose.

Therefore, the assembly worker is relatively troublesome and difficult in adjusting the nut to tighten the gasket to obtain the desired elastic clamping action or frictional resistance; in practice, the deformation deformation of the gasket is often caused, and the elastic clamp is caused. The enthalpy action or the frictional resistance in the process of using the rotating shaft causes different elastic unevenness or different resistance, which not only causes the rotating shaft to form a defective product, but also causes an increase in manufacturing cost; this situation is not what we expect. Typically, these references show the use and structural design of the shaft, positioning assembly or its associated assembly. If the redesign considers the structure of the reel and related components, and the above application, making it different from the conventional one, it will change its use type, which is different from the old one; in fact, it can not only improve the conventional skills. The occurrence of stress and deformation damage or wear of the component fit also increases its ease of assembly. For example, its structural design 10121220^WA〇101 4th page/total 20 pages 1012039224-0 M442007 The positioning structure can be obtained according to the diameter change of the rotating shaft under the condition of not increasing the assembly difficulty and the combined positioning component. The elastic clamping action or the adjustment mechanism of the frictional resistance; or the structure is different from the conventional one, and the process of using the rotating shaft in the old method is improved, and the uneven elasticity or the different resistance is generated. None of these topics have been specifically taught or disclosed in the above references. [New Content] [0003] The main purpose of this creation is to provide a hinge positioning structure that improves the complexity, inconvenience, and time-consuming and troublesome assembly of conventional positioning components under a condition that requires streamlining. The shaft includes a combination of a shaft body and a barrel; the barrel body having a chamber defined by a rigid wall and a rigid wall for receiving the shaft body. The shaft body includes at least one arcuate region and a planar region; and at least one elastic body is disposed on the cavity of the chamber to form a contact or interference state with the shaft body; and, in response to the movement of the shaft body Relatively generating a frictional resistance, a positioning function is formed to improve the situation in which the conventional positioning component is easily deformed and worn. According to the hinge positioning structure of the present invention, the elastic member includes a carrier portion and an arm portion; and the elastic member selects an elastic plate to form a pattern similar to a "[" shape. The carrier portion and the shaft body form a contact or interference state; and the arm portion is supported by the rigid wall of the cylinder; therefore, when the shaft body rotates, the carrier portion of the elastic body and the elastic member generate a frictional resistance to form Positioning effect. According to the present invention, the arcuate region and the planar region of the shaft body are formed on the surface of the shaft body; and the plane region includes a first planar region and a second planar region. The first plane 1() 12122()f single number A0101 5th page/total 20 page 1012039224-0 M442007 The interval configuration pattern formed by the region and the first planar region on the shaft body. The novelty, features, and other purposes and effects of the present invention will be hereinafter described in conjunction with the detailed description of the drawings, as shown in the drawings:

Referring to Figures 1, 2 and 3, the hinge positioning structure of the present invention comprises a combination of a shaft body and a cylinder; respectively, which are denoted by reference numerals 1 and 20, respectively. The shaft body 〇 and the barrel 2 can be mounted on an electronic object (for example, a mobile phone, a notebook computer, a driving recorder, a digital camera, etc.; not shown) to make the cover of the electronic object Or the display screen can be rotated to have an opening and closing function.

The figure shows that the shaft body 10 selects a type of columnar body and is joined to a head portion 1 3; the shaft body 1 includes at least one arcuate region 12 and a plane region 11 . The curved region i 2 and the planar region 11 are formed on the surface of the shaft body 1 ;; in the embodiment taken, the planar region 11 includes a first planar region 1 1 a and a second planar region 1 1 b. The first planar area 1 1 3 and the second planar area 1 1 b are formed on the shaft body 1 to form 18 〇. The spacer configuration patterns 1, 2 and 3 also depict that the cylinder 20 has a chamber 2 2 defined by a rigid wall 21 and a rigid wall 21, receiving the shaft body 10° and at least one The elastic device 3 is installed in the chamber 2 2 to form a contact or interference state with the shaft body 1; and, in response to the movement of the shaft body 10, a relative frictional resistance is formed to form a positioning function. 1012122〇单编号号 A0101 Page 6 / Total 2 page 1012039224-0 M442007 In the embodiment taken, the elastic body 3 includes a carrier portion 3 and an arm portion 3 2 ; and the elastic member 3 The 0 series selects an elastic sheet to form a pattern similar to the "[" shape. Therefore, the figure shows that the elastic device 30 has a carrier portion 31 and two arm portions 32. The carrier portion 31 is in contact or interference with the shaft body 1; and the arm portion 3 2 is supported by the rigid wall 21 of the cylinder 20; therefore, when the shaft body 10 is rotated, the shaft body The carrier portion 31 of the tether and the elastic member 3 产生 generates a frictional resistance to form a positioning action. φ [0007] In detail, at least one end of the elastic member 30 (i.e., the tail end of one of the arm portions 3 2 ) is provided with an extension portion 3 3 ; the extension portion 3 3 forms a claw-like type. Fitted on the barrel 2 〇. In the embodiment taken, the barrel 20 is provided with a notch 2 3 for combining the extension 3 3 ' of the elastic member 30 to fix the elastic member 30 in the chamber 22. [Fig. 3] Fig. 3 depicts the barrel 20 having a cover 2 4 for closing the chamber 2 2 of the barrel 20; and the shaft 1 and the head 1 3 are pivoted ' The head 13 is placed outside the cylinder 20. Further, the cover 24 can also restrict the shaft body 1 头部 and the head portion i 3 so that they do not cause looseness. [〇〇〇9] Fig. 3 also depicts the combination of the shaft body 1 筒, the barrel 2 〇 and the elastic element 30. The shaft body 1 is combined in the chamber 2 2 of the cylinder 2; and, in the figure, two elastic members 3 are attached to the chamber 2 2 to make the two elastic members 3 〇 The portions 31 are pressed against the first planar region 1 1 a of the shaft body 10 and the second planar region worker b, respectively. For convenience of explanation, the first plane area i 1 a and the second plane area are 1012039224-0 10121220# single number Α01ίΠ page 7/total 20 pages M442007 1 1 b load. PA spoons are indicated by numbers 3 1 a, 3 1 b. Therefore, in the initial combined position, the carrier portion 31a is in contact with the first planar region of the shaft body, and is in contact or interference state; the carrier portion 3 1 and the second planar region 11b form a contact or interference state; For example, the situation shown in Figure 4. It should be noted that the elastic device 3 clamps the clamping force of the first planar area 1 1 a of the shaft body and the second planar area 1 lb, so that the shaft body 10 and the head 13 do not rotate. . Moreover, the initial combined position is a false ax for the cover of the electronic object or the display of the landing position. In the closed position, please refer to FIG. 4, when the user operates the cover of the electronic object or the display screen moves from the closed position to the open or open position. When the head 13 and the shaft 1〇 are rotated, the first plane area i丄a and the second plane area 1 1 b are separated from the carrier 31 (or 31a, 31b), and the carrier 31a is caused. 31b moves relative to the curved region 1 2 . With the rotation of the shaft 1〇, the curved region 丄2 gradually presses the elastic device 30, so that the elastic member 3 〇 and the shaft body 1 〇 generate frictional resistance (or rotational torque), so that the cover or the display screen can be positioned at any time. . L 2J because the distance (or radius) of the arcuate region 12 to the center of the shaft body 1 大于 is greater than the distance from the first plane region 1 1 a (or the second plane region 1 1 b ) to the center of the shaft body 1 ;; When the shaft work is rotated to the position of Fig. 5, the frictional resistance formed by the shaft i 〇 and the elastic member 3 最大 is maximized, so that the elastic member 30 generates the maximum clamping force. If the cover 10 is continuously rotated or the screen is displayed to continue the rotation of the shaft body 10, the carrier portion 31b is pressed against the first plane area 1 1 a of the shaft body; the carrier portion 3 1 a is pressed at 10121220#单号Α01ίη Page 8 / Total 20 pages 1012039224-0 M442007 The second plane area of the shaft body is 1 1 b. Therefore, the elastic member 3 is pressed against the clamping force of the first planar region 1 1 a of the shaft body and the second planar region 丄 lb, and the body 10 and the head 13 are prevented from rotating. At this time, the cover or display screen of the electronic device is in a (fully) open position. Referring to Fig. 6, a modified embodiment is shown; the shaft body 10 and the head portion 13 are integrally formed. The end of the shaft body 10 is provided with a groove 14; after the shaft body is combined with the cylinder body 2, the groove 14 is pivotally connected with a buckle ring 15 so that the shaft body 1 〇 does not cause axial displacement. Therefore, the cover 24 that fits the cylindrical body 2 limits the shaft work and the head 13 so that they do not loosen. Typically, this shaft positioning structure has the following considerations and advantages under the conditions of operation rotation and positioning: Compared with the old method: [0015] 1. The shaft and related component structure (For example, the cylindrical body 2, the carrier portion 31 of the elastic member 30, the arm portion 32, etc.) cooperate with the elastic motion of the first and second planar regions 1 1 a, 1 lb, and the curved region 1 2 of the shaft body 1 〇 The type has been redesigned and has a streamlined structural design. Moreover, it also changed its use type, and the structure of the shaft body 1 〇, the cylinder 2 〇, and the elastic body 3, 0 is also different from the old method. The structural form of components such as sheets and friction plates. At the same time, 'the fitting structure of the positioning flange, the recess or the concave-convex positioning part is arranged on the relevant component. After a period of operation, the wear is often caused by the rigid contact with the matching plane, 1012122 humming single number A0101 Page 9 / Total 20 pages 1012039224-0 M442007 The positioning effect has become unsatisfactory, and so has also been significantly improved. 2. The cooperation structure of the first and second planar regions 11a, 11b, the curved region 12, the cylindrical body 20, and the elastic member 30 (for example, the carrier portion 3 1 and the arm portion 3 2) of the shaft body 10 is improved. The art of applying multiple gaskets and friction linings is a complex and time consuming situation in the overall structural design and assembly. Moreover, as in the old method, the assembly length of the positioning mechanism in the axial direction is too long, which affects and limits the arrangement space of the rotating shaft and the electronic object, and also provides significant improvement. 3. The normal portion of the elastic portion 30 of the elastic member 30 is pressed against the shaft body 10 to create a clamping force, which provides a cover, a screen or a display having any position between the open and closed positions or The positioning function of the angle" 4. Compared with the old method, the assembler adjusts the nut to tighten the pad; ί to obtain the ideal torque or frictional resistance, often causes the deformation of the gasket, the shaft is unstable or loose. In the case where the rotating shaft is formed into a defective product and the manufacturing cost is increased, a significant improvement is also obtained. Therefore, this creation department provides an effective hinge positioning structure, which is different from the conventional ones in terms of spatial type, and has the advantages unmatched in the old method. It shows considerable progress and has fully complied with the new patents. The essentials. However, the above is only a feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equal variation and modification of the patent application scope of the present invention is the scope of the creation patent 10121220 ^^^^ Α〇101 Page 10 of 20 pages 1012039224-0 M442007 Covered.
