Description

Technical Field

[0001] This utility model relates to the field of hinge torsion spring assembly technology, and in particular to a hinge torsion spring assembly structure. Background Technology

[0002] In the manufacturing of foldable screen phone hinges, the torsion spring, as a core mechanical component of the hinge, directly determines the hinge's opening and closing feel and long-term reliability through its assembly quality. The assembly of the hinge torsion spring is a crucial and highly complex step in the hinge manufacturing process.

[0003] Currently, traditional hinge torsion spring assembly mainly relies on manual operation. Operators use needle-nose pliers to hold a miniature torsion spring, manually compressing it to the target deformation state based on experience before embedding it into the hinge base. However, manual compression of the torsion spring makes precise control of the applied pressure difficult; even slight fluctuations can cause irregular bouncing, causing the spring to deviate from the intended compression path or even dislodge from the pliers. This not only increases the difficulty and time of assembly but also causes varying degrees of damage to the torsion spring. Furthermore, purely manual assembly cannot guarantee the consistency of the assembled torsion spring's performance, thus affecting the overall performance and long-term reliability of the hinge, failing to meet the high-quality and high-efficiency requirements of modern hinge manufacturing. Utility Model Content

[0004] Based on this, the present invention provides a hinge torsion spring assembly structure, which is simple in structure and easy to use. By utilizing the coordinated cooperation of the first rotating mold, the floating sleeve, the flap and the pressure cover, the stability and positional accuracy of the torsion spring during the assembly process are ensured. This avoids the problem of the torsion spring deviating from the predetermined compression path or falling out due to the difficulty in accurately controlling the pressure during manual compression. It also reduces the damage to the torsion spring caused by repeated clamping and compression, and ensures the consistency of the performance of the assembled torsion spring, thereby improving the overall performance and long-term reliability of the hinge.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Please see Figures 1 to 7 This invention provides a hinge torsion spring assembly structure, comprising a support component 10, a torsion spring flipping component 20 mounted on the support component 10, and a cantilever assembly component 30 located above the torsion spring flipping component 20. The hinge torsion spring can be assembled via the torsion spring flipping component 20 and the cantilever assembly component 30. Specifically, as shown... Figure 8 As shown, during assembly, the torsion spring 41 is first embedded into the hinge base 42. Then, two pivots 43 are used to pass through the spring body 411 of the torsion spring 41 and protrude from the top of the hinge base 42. Next, the two cantilever arms 44 are fitted with the parts of the pivots 43 that protrude from the top of the hinge base 42. Finally, the hanging feet 412 of the torsion spring 41 are fastened into the fastening grooves 440 on the side of the cantilever arm 44 to complete the assembly of the entire hinge torsion spring.

[0032] The supporting component 10 includes a base plate 11, a vertical plate 12 installed at one end of the base plate 11, and a manual valve 13 installed at the other end of the base plate 11. A support seat 14 is installed on one side of the bottom end of the vertical plate 12, and a first magnet 15 is installed on the inner wall of the support seat 14.

[0033] The torsion spring flipping assembly 20 includes a first rotating mold 21 detachably mounted on the bottom of the upright plate 12, two floating sleeves 22 floatingly connected to the first rotating mold 21, a flap 23 connected to one side of the top of each floating sleeve 22, a second rotating mold 24 mounted on the top of the first rotating mold 21, and a push rod 25 movably mounted on one side of the first rotating mold 21. The first rotating mold 21 is fitted inside the support base 14, and a first magnet 15 is used to hold the first rotating mold 21 in place, thus achieving the positioning and installation of the first rotating mold 21.

[0034] like Figure 4 and Figure 5As shown, the suspension sleeve 22 is a cylindrical structure with a completely through interior. Specifically, a fixing post 211 is installed inside the first rotating mold 21, and a spring 212 is fitted onto the fixing post 211. The top end of the suspension sleeve 22 accommodates the bottom end of the rotating shaft 43, and the bottom end of the suspension sleeve 22 is fitted onto the fixing post 211. The spring 212 elastically supports the bottom end of the suspension sleeve 22, thus achieving a floating connection between the suspension sleeve 22 and the first rotating mold 21. Inside the suspension sleeve 22, the bottom end of the rotating shaft 43 abuts against the top end of the fixing post 211. Therefore, when the suspension sleeve 22 slides up and down along the fixing post 211, the torsion spring 41, the hinge base 42, and the rotating shaft 43 can maintain their positions, providing a stable support environment for subsequent assembly operations.

[0035] In this embodiment, the top of the flap 23 is used to elastically support the cantilever 44, and the end of the flap 23 away from the suspension sleeve 22 is wedge-shaped. Figure 4 As shown, when the two flaps 23 are brought close together, they are positioned between the two hanging feet 412 of the torsion spring 41. When the two flaps 23 are brought close together, a V-shaped receiving groove 26 is formed between them, which is used for the insertion of the push rod 25. Figure 5 and Figure 6 As shown, as the push rod 25 is pushed forward, the two flaps 23 can be flipped outward and unfolded, thereby opening the two hanging feet 412 of the torsion spring 41, preparing for the subsequent assembly of the cantilever 44 and the torsion spring 41.

[0036] Please refer to it again. Figure 4 The second rotating mold 24 has a mating surface 241 at one end, and a second magnet 242 is installed on the second rotating mold 24 corresponding to the middle of each mating surface 241. The mating surface 241 is used to abut the cantilever 44, and the second magnet 242 is used to position and attract the cantilever 44, so as to facilitate the subsequent assembly of the cantilever 44 and the torsion spring 41 by the cantilever assembly assembly 30.

[0037] In this embodiment, the bottom surface of the push rod 25 is connected to the base plate 11 via a guide rail pair. The end of the push rod 25 away from the first turnover mold 21 is connected to a telescopic cylinder 250, which controls the telescopic movement via a manual valve 13. By using the telescopic cylinder 250 to drive the push rod 25 to extend or retract, the two adjacent flaps 23 can be flipped, thereby opening the two hanging feet 412 of the torsion spring 41.

[0038] Furthermore, in this embodiment, the end of the push rod 25 is generally tapered or semi-circular, which allows the push rod 25 to be embedded inside the receiving groove 26 and to facilitate pushing the two flaps 23 to flip and unfold each other. It is not limited to tapered or semi-circular, but can also be other shapes.

[0039] The cantilever assembly 30 includes a pressure cover 31 that can be raised and lowered to connect to the upright plate 12, and a pusher 32 installed above the pressure cover 31. The pressure cover 31 is located above the first rotating mold 21 and is slidably connected to the upright plate 12 via a guide rail pair. The pusher 32 is fixedly installed on the upright plate 12 and is used to drive the pressure cover 31 to press down against the cantilever 44, so that the cantilever 44 synchronously pushes the flap 23 and the suspension sleeve 22 down. Since the torsion spring 41 remains in a fixed position, such as Figure 7 As shown, when the cantilever 44 and the flap 23 move downwards, the hanging foot 412 moves from the flap 23 into the latching groove 440 of the cantilever 44, thus assembling the cantilever 44 with the torsion spring 41. Simply put, the hanging foot 412 was originally abutting against the flap 23, and then the cantilever 44, during its movement, replaces the position of the flap 23, causing the hanging foot 412 to latch into the latching groove 440 of the cantilever 44. During this process, the included angle between the two flaps 23 is greater than the included angle between the two cantilever 44, which facilitates the repositioning of the hanging foot 412.

[0040] In this embodiment, the pusher 32 is a quick clamp. Of course, in other embodiments, the pusher 32 can also be other linear drive modules, not limited to the quick clamp in this embodiment, as long as it can perform the same linear drive function.

[0041] The aforementioned hinge torsion spring assembly structure is simple in structure and easy to use. By utilizing the coordinated operation of the first rotating mold 21, the suspension sleeve 22, the flap 23, and the pressure cover 31, the stability and positional accuracy of the torsion spring 41 during the assembly process are ensured. This avoids the problem of the torsion spring deviating from the predetermined compression path or falling out due to the difficulty in accurately controlling the pressure during manual compression. It also reduces the damage to the torsion spring 41 caused by repeated clamping and compression, and ensures the consistency of the performance of the assembled torsion spring, thereby improving the overall performance and long-term reliability of the hinge.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
