Description

Tube spring type arrow type pivot

The invention relates to a tube spring type inline pivot, in particular to a pivot device suitable for an electronic device such as a notebook computer, which has better torque control and stability, and facilitates an assembly process.

The conventional inline pivoting device is mainly composed of a male shaft and a female shaft. The male shaft is provided with a torsion portion, and the female shaft is provided with a sleeve inserted into the torsion portion of the male shaft to form a required torque. The positioning function, the female shaft sleeve is provided with a spiral notch, so that the positioning of the pivot shaft can be achieved by the action of the spiral notch during the rotation of the male shaft. However, such a conventional inline pivot structure is susceptible to the pivot positioning function due to the deformation of the spiral notch described above.

In this regard, the new patent M276431 "One-Piece Hub" provides an improved structure, mainly consisting of a torsion with a free end on a male shaft, the sleeve of the mother shaft is provided with an arc-shaped notch and a forcing Long gap of tension. The male shaft sleeve is easily deformed by inserting the free end of the male shaft into the fitting portion provided behind the arcuate notch and inserting the torsion portion into the elongated notch inner hole for forming the tension. Disadvantages, but because the torsion positioning structure is directly disposed on the mother shaft sleeve, the torsion control structure and stability of the entire pivot is still not ideal.

The new patent M279160 "One-Piece Hub" provides another one-piece pivot structure. The sleeve of the parent shaft is also provided with a curved notch and a tension for forming the tension. Long notch, but in order to make the upper cover of the electronic device and the base can be positioned relative to each other, the shaft with a relatively flat plane is provided on the male shaft to reduce friction, and the twist inserted into the long notch cannot drive a separate joint. It expands outward, but since the torsion positioning structure is directly placed on the female bushing, the torsion control structure and stability of the entire inline pivot can still not be improved. In this regard, the new patent M326766 "Positioning Structure of the Hub" provides another improved pivoting device in an attempt to improve the function of the above-mentioned new patent M279160, but it must additionally provide components such as a coil spring, a joint and a relative bracket, and Such a flat-type pivot has considerable variability.

The novel features and other features of the invention are disclosed in the description

As shown in FIGS. 1 to 3, the present invention includes a male shaft 10 and a female shaft 20, wherein The male shaft 10 is provided with a fixed end 11 for assembling to the electronic device, and a shaft 12 of a set diameter and length, and a hook 13 is arranged at one end of the shaft 12; the female shaft 20 is also provided with a set Connected to the fixed end 21 of the electronic device, and a shaft hole 22 of a size and a diameter, the shaft hole 22 is provided at the inner end with an arc surface portion 23 and a positioning hole 24 at the center of the arc surface portion 23, and The shaft hole 22 is provided with a slot 25 for engaging the hook 13 near the front end surface, and a guide groove 26 is provided inside the shaft hole 22.

The shaft 12 of the above-mentioned male shaft 10 is provided with one or more round members 30, and in this embodiment, two sleeve-type round members 30 are provided, and the round members 30 are provided with a matching shaft 12. An inner hole 31 having a diameter and an elastic notch 32, and an outer protruding piece 33 is disposed on the outer circumference of the circular member 30. In the preferred embodiment, the elastic notch 32 is provided with an outrigger on one side. 33. Preferably, the elastic notch 32 of one of the round members 30 of the round member 30 is located on the left side of the overhanging insert 33, and the elastic notch 32 of the other round member 30 is located on the right side of the overhanging tab 33, thereby forming an ideal one. Torque structure.

The shaft 12 of the male shaft 10 can be inserted into the round member 30 in a slightly forced force structure, and then assembled into the shaft hole 22 of the female shaft 20 to position the circular member 30 on the male shaft 10 The outer circumferential surface of the shaft 12 and the inner circumferential surface of the shaft hole 22 of the female shaft 20, and the outer protruding piece 33 is inserted into the inner guiding groove 26 of the shaft hole 22 (see FIGS. 3 and 4). At the same time, a partial length of one end portion of the shaft 10 of the male shaft 10 is inserted into the positioning hole 24 at the inner end of the shaft hole 22. After the male shaft 10 shaft 12 is positively inserted and positioned, the above-mentioned card slot 25 which is preset to the front end surface of the shaft hole 22 will engage with the hook 13 of the end portion of the shaft 12 .

As shown in FIG. 5, in the above-mentioned plugging process, the partial length of the end portion of the shaft 10 of the male shaft 10 first abuts against the preset arc surface portion 23, so that the shaft 10 of the male shaft 10 is assembled. process The effect of being guided is more conducive to the assembly process.

According to the above configuration, when either of the male shaft 10 or the female shaft 20 is rotated by the deflection of the electronic device, the male shaft 10 forces the above-mentioned circular member 30 to be subjected to a rotational force to form a desired positioning function.

In another possible embodiment of the present invention shown in FIGS. 6 to 8, the round member 300 is composed of a plurality of shim-like wrap members 300, and the shim-like wrap member 300 is also provided with a diameter of the shaft 120. The inner hole 310 is provided with an elastic notch 320 at one end and an overhanging tab 330 at the other opposite end.

The present invention thus forms a new inline pivoting member, since the wrap member 30 for forming the desired torsion positioning function is disposed between the male shaft 10 and the female shaft 20 in a completely new spring-like configuration, rather than The outer peripheral wall of the female shaft 20 is directly formed, which can improve the common problem that the in-line pivoting torque structure is easy to be deformed, and the torque control and stability of the entire inline pivoting device are more excellent and durable. At the same time, since the local length of the male shaft 10 as the positioning end is guided and assembled during the assembly process, it is more accurate and reliable, and facilitates the assembly operation procedure in the factory.
