Description

Cushion-to-pivot construction for clamshell phone cases

technical field

The utility model relates to a pivot shaft, in particular to a pivot shaft structure which is applied to the pivot of a cover-type mobile phone casing and can achieve smoother buffering of the pivot when the cover is lifted or closed.

Background technique

The current popular flip-type mobile phone case is to install a group of rotating shafts at the hinge of the flipping cover, and a group of torsion springs are embedded in the rotating shaft, so that when the mobile phone case is flipped, it can be quickly lifted by the rebound force of the torsion springs. However, the existing pivot structure is only opened by the torsional elasticity of the torsion spring, not only the flipping speed is too fast, but also it is easy to cause some slight forward rebounding force when the flip reaches the extreme opening angle. In this way, when the mobile phone is flipped and used repeatedly for a long time, the rebound force is likely to cause secondary damage to the pivot of the casing, resulting in loose pivots, and even cracks in the pivot components, and the rebound force will also produce some noise. question.

Contents of the invention

The purpose of this utility model is to provide a kind of cushioning and pivoting structure of the cover-type mobile phone casing, the sleeve is pivoted on a shaft and the cushioning pivot set is divided into a pivoting part and a fixed shaft to be combined with each other. The pivoting shaft is placed in the casing tube and pivoted in unison, and one end surface is supported by the spring assembly and keeps in normal contact with the fixed shaft, while the mating surface of the pivoting shaft and the fixed shaft is in the shape of A long-distance helical alignment line, when the cover is lifted or closed, the spring assembly can be used to push one end of the pivoting shaft against the thrust generated by the fixed shaft, so that the pivoting shaft is subjected to the thrust and Guided by the curved section, the pivot is displaced along the long-distance helical path of the curved section of the fixed shaft, so that the pivot of the flip cover case has a smoother cushioning effect.

Another object of the present invention is to provide a buffer pivot structure for a clamshell mobile phone case. By utilizing the limitation of the pivot displacement of the helical trace of the mating surface of the pivot element and the fixed axis element, the spring assembly can be suppressed. Hold the rebound force after the collision, so that the cover can achieve a silent effect when the cover is pivoted.

The utility model will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

Detailed ways

Please refer to Figures 1 to 3, the buffer pivot structure of the flip-top mobile phone case of the present invention mainly includes: a shaft 1, a shell tube 2, a spring assembly 3 and a pair of buffer pivot sets 4, wherein the shaft 1 has a block end 11 with a large cross-sectional area at one end, and a pair of lug ends 12 extending outward at the other end, and one end of the casing tube 2 is an inner groove 21 with a hole, and the other end A hollow tube with a closed surface at one end and a shaft hole 22 through the center, and two sets of parallel and corresponding flat cut surfaces 23 are provided on the outer edge of the casing tube 2, allowing the casing tube 2 to be nested and fixed in the capping machine In the pivot hole 51 of the shell 5, when the flip cover casing 5 is flipped, the casing tube 2 can be pivotally rotated (as shown in FIG. 4 ).

As shown in Figure 3, the shaft 1 can be extended from the central axis hole 22 on the closed surface of the casing tube 2 to the inner groove 21 of the casing tube 2, so that the blocking group end 11 of the shaft rod 1 is blocked. Set outside the opening inner groove 21 of the casing tube 2; the above-mentioned spring assembly 3 and mating buffer pivot set 4 are respectively inserted into the shaft 1 in sequence and accommodated in the opening inner groove 21 of the casing tube 2 .

Referring to FIG. 2 , the above-mentioned mating buffer pivot set 4 is formed by a rotating pivot 41 and a fixed shaft 42 mutually mating to form a cylindrical shaft, wherein the rotating pivot 41 is provided with an available shaft 1 The lug end 12 penetrates into the axial central hole 411 of the straight shape, which is used for the pivoting shaft 41 to be sleeved on the shaft 1 to pivot, and the pivoting shaft 41 is sleeved and pivoted on the shaft One end surface of 1 is supported by the spring assembly 3, while the other end surface is set as a long-distance spiral curved arc cut surface 412. The flat cut surface 413 matched with the flat cut surface 23 is used to enable the pivoting shaft member 41 to be nested and positioned in the opening inner groove 21 of the casing tube 2, and to move together with the casing tube 2; in addition, the fixed shaft member 42 is provided with a cross-shaped axial center hole 421 for the lug end 12 of the shaft 1 to pass through and fix, so that the fixed shaft 42 can be fixed on the end surface of the lug end 12 of the shaft 1, and the fixed Shaft member 42 is also arranged as the curved arc cut surface 422 of the same helical alignment track with the curved arc cut surface 412 on the mating surface of the pivot shaft member 41, and a square column shaft with a smaller cross-sectional area is set on the other end face 423, for nesting and fixing in the pivot hole 61 on one side of the lower casing 6, so that the fixed shaft member 42 is limited and does not rotate, and the shaft rod 1 is also stretched across the opening inner groove 21 of the casing tube 2 The center is locked and limited by the lug end 12 and does not rotate (as shown in Figure 4).

As shown in Fig. 4 and Fig. 5, in the specific application and implementation of the present invention, when the flip cover casing 5 is flipped or closed, the flip cover casing 5 can also move the casing tube 2 to rotate and pivot and the pivoting shaft member 41 is pivoted on the shaft rod 1 and can also be pivoted together. At the same time, one end of the pivoting shaft member 41 is supported by the spring assembly 3, and the pair of the pivoting shaft member 41 and the fixed shaft member 42 The joint surface is designed as a long-distance helical alignment line, so the pivoting shaft 41 is subjected to the thrust generated by abutting against the fixed shaft 42, and is influenced by the guidance of its curved section 412, so that the pivoting shaft 41 The curved arc section 412 can delay the pivot displacement (as shown in FIG. 3 ) along the long-distance helical trace path of the curved arc section 422 of the fixed shaft 42, and then achieve the function of flipping and closing the cover casing 5. The swivel pivot buffers more smoothly, and the limitation of the swivel pivot displacement by using the helical trace can also suppress the rebound force of the spring assembly 3 after the collision, so as to achieve the mute effect.
