DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] See also Figures 1 to 7 , which is a bidirectional positioning structure 100 of a preferred embodiment of the present invention, includes a fixing member 10, a rotating member 20 movably connected to the fixing member 10, and an elastic member 30. A groove is provided at one end of the fixing member 10 close to the rotating member 20. The groove includes an inclined surface 11 and an abutting surface 12 connected to the inclined surface 11. A circular arc transition section 13 is provided at the connection between the inclined surface 11 and the abutting surface 12. The elastic member 30 includes a first rebound portion 31 and a second rebound portion 32. The first rebound portion 31 and the second rebound portion 32 are symmetrically arranged. One end of the elastic member 30 is connected to the rotating member 20, and the other end of the elastic member 30 abuts the abutting surface 12. When the elastic member 30 is rotated to a preset angle, it generates a positive force on the rotating member 20, thereby realizing the locking and positioning of the rotating member 20 and the fixing member 10, and no rebound phenomenon occurs, and it has a good bidirectional positioning function.

[0028] Furthermore, it also includes a rotating shaft (not shown), an extension block 21 is provided at both ends of the rotating member 20, a receiving groove is formed between the extension block 21 and the rotating member 20, a through hole 22 is provided on the extension block 21, and a limiting protrusion 14 is provided on the fixed member 10, and the limiting protrusion 14 is provided with a through connecting hole 15, and the rotating shaft is penetrated with the through hole 22 and the connecting hole 15, so that the rotating member 20 is movably connected to the fixed member 10. Among them, the relative horizontal height of the extension block 21 changes by rotating with the rotating shaft as the turning point of the rotating member 20, so that the elastic member 30 connected to the extension block 21 undergoes compression deformation and rotation, and finally the elastic member 30 overcomes the gravity of the rotating member 20 and the additional components on the rotating member 20 to provide a positive force, and avoids the rebound image after the two-way positioning. At the same time, the limiting protrusion 14 and the extension block 21 also play a limiting role, avoiding the displacement or dislocation of the rotating member 20 and the fixed member 10 during the toggle operation, and further improves the accuracy of the operation. It can be understood that the through hole 22 and the connecting hole 15 are set to penetrate, which can ensure the connection of the rotating shaft, and realize the use of a single or multiple combinations of two-way positioning structures 100, which can be adjusted according to the actual application scenario and production conditions; that is, multiple two-way positioning structures can be connected by the same rotating shaft, which can be suitable for two-way positioning processing of larger mass such as folding screens of mobile phones, and a single two-way positioning structure can also be used for two-way positioning processing of lighter mass such as folding headphone storage boxes, which can effectively save assembly parts, make product design more orderly, and improve the integrity and lightness of the product.

[0029] Furthermore, the extension block 21 is provided with a through hole 23, and one end of the first resilient portion 31 and the second resilient portion 32 are respectively installed in the through hole 23. It can be understood that the number of the extension blocks 21 is two, that is, the number of the through holes 23 is also two and they are respectively located on both sides of the elastic member 30, and the top two ends of the elastic member 30 are respectively installed in the through holes 23, thereby realizing the connection operation between the rotating member 20 and the elastic member 30. The two-side connection method can improve the compression accuracy and stability, ensure that the extension block 21 of the rotating member 20 effectively compresses the elastic member during the rotation process, and avoid the shortcomings of insufficient compression and weak stability of the elastic member 30 existing in the single-side connection.

[0030] Furthermore, the extension block 21 and the rotating member 20 are an integrally formed structure, and the limiting protrusion 14 and the fixing member 10 are an integrally formed structure. The use of an integrally formed structure can further improve the overall strength of the rotating member 20 and the fixing member 10, and is also convenient for improving production efficiency and saving time costs. It can be understood that in other embodiments, corresponding adjustments can be made according to actual production needs, that is, the extension block 21 and the rotating member 20 can be a single structure setting, and the extension block 21 and the rotating member 20 can be a single structure setting; similarly, the connection method of the limiting protrusion 14 and the fixing member 10 can also be adjusted accordingly.

[0031] Further, the elastic member 30 is a spring or an elastic sheet. In the present embodiment, the first resilient portion 31 and the second resilient portion 32 are springs arranged in a Z shape, the bottoms of the first resilient portion 31 and the second resilient portion 32 are connected to each other and are symmetrically arranged, the bottoms of the first resilient portion 31 and the second resilient portion 32 abut against the abutment surface 12, and the tops of the first resilient portion 31 and the second resilient portion 32 are respectively connected to the through holes 23 of the extension block 21. In the second embodiment, the elastic member 30 can also be other symmetrical springs or elastic sheets, and the elastic member 30 can be a spring or elastic sheet arranged in a W shape; in the third embodiment, the elastic member 30 can be a spring or elastic sheet arranged in a V shape. It can be understood that the shape of the elastic member 30 can be adjusted according to the actual production conditions, and it should be ensured that the left and right ends of the elastic member 30 are symmetrically arranged, and the compression degree and the rebound force on both sides of the elastic member 30 are the same, so as to avoid the phenomenon of inconsistent compression deformation and rebound force. In this embodiment, elastic rings 33 are provided at both the upper and lower ends of the first resilient part 31 and the second resilient part 32, and the elastic rings 33 at the upper ends of the first resilient part 31 and the second resilient part 32 are symmetrically arranged. The elastic rings 33 can be elastically deformed to ensure that both the upper and lower ends of the elastic member 30 can be deformed, so that the elastic member 30 can achieve a two-way positioning function after the rotating member 20 is folded closed or folded unfolded. It can be understood that in other embodiments, the number of elastic rings 33 of the elastic member 30 can be adjusted; for example, the top two ends of the V-shaped elastic member 30 can be provided with symmetrical elastic rings 33, and the bottom of the V-shaped elastic member 30 can also be provided with an elastic ring 33; or the top two ends of the V-shaped elastic member 30 are provided with commonly connected elastic rings 33, and a single elastic ring 33 is provided at the bottom to achieve a two-way positioning function.

[0032] Furthermore, a fixing groove 16 is provided on the side of the fixing member 10 facing away from the groove, and the fixing groove 16 is used to connect the fixed shell of the external device, thereby realizing the assembly processing of the fixing member 10; the rotating member 20 is provided with an L-shaped end face 24, and installation grooves 25 are provided on both sides of the end face 24. The end face 24 and the installation grooves 25 are used for placing foldable parts such as flexible folding screens or earphone storage boxes, thereby realizing the assembly processing of folding mobile phones or folding earphone storage boxes.

[0033] The working principle of a bidirectional positioning structure 100 is as follows: when the rotating member 20 rotates from the expanded state to the closed state, the rotating member 20 is caused to move clockwise by the action of external force to rotate the elastic member 30, and the relative horizontal height of the extension block 21 of the rotating member 20 gradually decreases, causing the upper end of the elastic member 30 to move downward and compress and deform. At the same time, the elastic ring 33 at the lower end of the elastic member 30 will gradually fit the inclined surface 11. When the elastic member 30 fits the inclined surface 11, a positive force will be generated on the rotating member 20, so that the rotating member 20 obtains a closing support force after closing, thereby avoiding the rebound phenomenon of the rotating member 20 and realizing the locking process of the closed state. When the rotating member 20 rotates from the closed state to the expanded state, the rotating member 20 is prompted to move clockwise by external force to rotate the elastic member 30, and the relative horizontal height of the extension block 21 of the rotating member 20 gradually rises, prompting the lower end of the elastic member 30 to be the turning point and rotate to gradually move away from the inclined surface. When the rotating member 20 rotates to the preset position, the positive force generated by the elastic member 30 is greater than the gravity generated by the rotating member 20, prompting the rotating member 20 to obtain an expansion support force after the expansion is completed, thereby preventing the rotating member 20 from falling back, realizing the locking process of the expanded state, and finally realizing the bidirectional positioning function of the rotating member 20, and being able to realize the bidirectional rotation locking function in a limited space.

[0034] A bidirectional positioning structure of the present invention generates a positive force on the rotating part when the elastic part rotates to a preset angle or a preset position, thereby achieving locking and positioning of the rotating part and the fixed part without rebounding. It has good bidirectional positioning function and can achieve bidirectional rotation locking function in a limited space.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
