a thin hinge

technical field

The utility model belongs to the field of hinges, and in particular relates to a thin hinge, in particular to a thin hinge which is implemented by an arc-shaped linking part and can be thinned.

Background technique

Generally, clamshell electronic devices, such as notebook computers, mobile phones, etc., use hinges to pivotally connect the display of the electronic device to the host body. Generally speaking, the hinge mainly includes a pivot and two connecting parts pivotally connected to the pivot and respectively connected to the display of the electronic device and the host body. When in use, the display can be opened and operated only after being opened relative to the main body; and when not in use, it can be folded only by folding the display in half relative to the main body. Through the setting of the hinge, the volume of the clamshell electronic device can be greatly reduced to achieve the effect of convenient storage and portability.

However, the existing hinge mainly includes a seat, two pivots arranged side by side on the seat and respectively assembled with the display and the main body, and two torque generating members respectively arranged corresponding to the pivots. However, because the two pivots are arranged side by side in the existing hinge, the volume of the hinge cannot be reduced, which limits the thinning of the electronic device equipped with the hinge. In addition, the torque generating part used in the existing hinge is formed by stacking a plurality of reeds in sequence, and then the degree of tightness between the reeds is adjusted by turning the adjusting nut on the torque generating part to When the hinge is implemented, a rotating torque is provided to the configured pivot. However, in the existing structure, each torsion generating member is respectively arranged on one of the pivots, during the assembly process, the torsion needs to be adjusted for each torsion generating member, so that the hinge cannot be guaranteed. Whether the torsional forces that the two pivots bear during the rotation are the same is not conducive to implementation.

Further, the arc-shaped linkage 12 is arranged in the accommodation space 112, which has an active part 121, a curved part 122 connected to the active part 121, and extends from the curved part 122 toward the active part 121 and extends in the direction of the assembly part 113. The driving part 123 is assembled with the assembly part 113 to form a pivotal relationship. To further illustrate, the arc-shaped linking member 12 is assembled with the upper casing 21 of the electronic device 2 and is driven by the upper casing 21 . The acting part 121, the bending part 122 and the driving part 123 on the arc linkage 12 can be implemented in an integrated manner, wherein the acting part 121 has to be implemented as a linear flat plate, and the shape of the bending part 12 can be implemented according to the implementation. According to the above requirements, the curvature is changed accordingly, and the driving part 123 can extend away from the bending part 122 toward the direction of the acting part 121, so that the driving part 123 has a deformation angle 125 relative to the horizontal extension line 124 of the acting part 121, which The appearance can be seen in Figure 4. In this way, it is possible to avoid the problem of structural interference of various components in the process of assembling, which is unfavorable for assembling. Furthermore, in one embodiment, the seat 11 can further have a pivot 117 disposed on the assembling portion 113 to form a pivoting relationship with the driving portion 123 .

Please refer to Fig. 2 to Fig. 4, the torque generating assembly 13 includes at least one driving arm 131 arranged at the junction of the driving part 123 and the bending part 122 of the arc linkage 12, connected to the driving arm 131 and corresponding to the linear slide rail 114 located in the accommodating The sliding seat 132 in the storage space 112, the corresponding sliding seat 132 is arranged on the linear slide rail 114 facing the blocking piece 133 on the other side of the accommodating space 112, and at least one corresponding blocking piece 133 forms an assembly relationship with the sliding seat 132 and the blocking piece 133 The torsion spring 134 provides torsion force when the sliding seat 132 slides on the linear slide rail 114 in conjunction with the driving arm 131 . More specifically, in one embodiment, the sliding seat 132 includes a plurality of mounting pieces 135 arranged on both sides of the driving arm 131 to clamp the driving arm 131 therein, that is to say, the sliding seat 132 is composed of a plurality of mounting pieces 135 formed. Further, in order to increase the structural strength between the sliding seat 132 and the driving arm 131, in one embodiment, the torque generating component 13 includes two driving arms 131, and the two driving arms 131 and the mounting piece 135 are spaced apart.

Moreover, the driving arm 131 has to be further designed with a geometric notch on the side of the driving arm 131 facing the assembly part 113, as shown in FIG. Excessive exposure to the thin hinge may interfere with other components of the electronic device 2 or be unfavorable for users. In addition, the setting position and shape of the geometric notch should be appropriately adjusted according to the actual requirements. Please refer to Fig. 5-1 to Fig. 5-2 again. In order to clearly explain the implementation process of the thin hinge 1 of the present invention, it is presupposed that the thin hinge 1 is in an unused state, that is, the arc connector 12 is not relatively supported.

When the action part 121 is driven by the force applied by the outside and turns away from the seat 11, the action part 121 121 will drive the bending part 122 at the same time, so that the driving part 123 will produce a corresponding rotation, and the rotation generated by the driving part 123 will push the driving arm 131 at the same time, so that the driving arm 131 will push the slide seat 132 away from the driving part along the linear slide rail 114 123 direction displacement, while the sliding seat 132 slides on the linear slide rail 114, it will be subjected to the torsion force provided by the torsion spring 134, which limits the sliding speed of the sliding seat 132, preventing the user from quickly operating the thin hinge 1 Problems occur that cause damage to its structure.

To sum up, the thin hinge of the present invention includes a seat, an arc-shaped linkage and a torsion generating component. The seat has a seat body, an accommodating space formed on the seat body, an assembly part arranged at one end of the seat body, and a linear slide rail arranged at the other end of the seat body opposite to the assembly part and communicating with the accommodating space. The arc-shaped linkage is arranged in the accommodation space, and has an active part, a curved part connecting the active part, and a driving part extending from the curved part toward the active part and assembled with the assembly part to form a pivotal relationship.
