Description

pivot assembly

technical field

The invention relates to a connection device, in particular to a pivot assembly.

Background technique

Many electronic devices have components that can move or rotate relative to each other. For example, the screen of a foldable mobile phone can rotate in various ways relative to the main body. In order to still achieve the electrical connection between the elements during rotation, two types of connecting pivot assemblies are known.

One of them can be called hollow type. A circuit connection device, usually a flexible printed circuit board (FPC), passes through the hollow connection pivot to electrically connect two relatively rotatable components. Since the connectors at both ends of the flexible printed circuit board are to pass through the hollow connection pivot hole to complete the assembly, the size of the connectors at both ends of the flexible printed circuit board must not be larger than that of the connection pivot cavity. size. As the size design of general mobile electronic devices becomes smaller and smaller, the size design of the connection sockets at both ends of the flexible printed circuit board becomes more and more difficult.

The other can be called the winding type. Utilizing the flexible advantage of the flexible printed circuit board, the flexible printed circuit board is wound like vines between the two movable components connecting the pivot, so as to match the outgoing direction of the circuit design. However, when assembling on the production line, the winding and outlet position of the flexible printed circuit board often cause assembly difficulties. Moreover, during the rotation and swing tests, the flexible printed circuit board will inevitably rub against the connecting pivot, which will easily cause the flexible printed circuit board to be worn and become a defective product.

Therefore, there is a need for a pivot assembly that not only relaxes the size restriction on the connecting seats at both ends of the flexible printed circuit board, but also does not increase the difficulty of the existing assembly or make the flexible printed circuit board excessively rub against the connecting device.

The invention provides a pivot assembly and an electronic device including the pivot assembly. If it is used together with the electrical connection element, the size limit of the connection seats at both ends of the electrical connection element will be relaxed, and at the same time, the difficulty of assembly will be reduced. Based on a preferred embodiment of the present invention, the pivot outer ring and the pivot inner ring in the pivot assembly can be connected in various ways to meet various requirements.

Please refer to FIG. 1A , which shows an exploded view of a preferred embodiment of the pivot assembly according to the present invention. In FIG. 1A , the pivot assembly is composed of a pivot outer ring 120 and a pivot inner ring 110 .

Wherein, the pivot inner ring 110 can be installed with an inner ring flange 111 on its upper edge, and the inner ring flange 111 is used for connecting any electronic device (not shown). In addition, the pivot inner ring 110 also has an inner ring split groove 112 , the inner ring split groove 112 runs through the sidewall of the pivot inner ring 110 and connects two ends of the pivot inner ring 110 along the axis A-A. The flange 111 of the inner ring may further include a screw hole for the fixed connection of the pivot inner ring 110 and the electronic device.

The pivot outer ring 120 can also be provided with an outer ring flange 121 on its lower edge, and the outer ring flange 121 is used to connect any electronic device (not shown). Similarly, the pivot outer ring 120 also has an outer ring split groove 122 , and the outer ring split groove 122 runs through the sidewall of the pivot outer ring 120 and connects two ends of the pivot outer ring 120 along the axis A-A. The flange 121 of the outer ring can also include a screw hole for the fixed connection of the pivot outer ring 120 and the electronic device.

Referring to FIG. 1B , it shows an assembly view of a preferred embodiment of the pivot assembly of the present invention. The pivot inner ring 110 is sleeved in the pivot outer ring 120 and can rotate along the axis A-A.

The pivot inner ring 110 and the pivot outer ring 120 respectively have an inner ring fixing part and an outer ring fixing part. The inner ring fixing part and the outer ring fixing part are combined with each other so that when the pivot inner ring rotates relative to the pivot outer ring not loose from each other. The shapes of the inner ring fixing member and the outer ring fixing member will be exemplified later, but are not limited to these examples. For example, in this embodiment, as shown in FIG. 1A , the inner wall of the pivot outer ring 120 has a protruding annular hook 123 , while the outer wall of the pivot inner ring 110 has an annular groove 113 . During assembly, the above-mentioned annular hook 123 is embedded in the annular groove, so that the pivot inner ring 110 will not be loosened when rotating relative to the pivot outer ring 120 . However, the annular groove 113 can also be disposed on the inner sidewall of the pivot outer ring 120 , and the annular hook 123 can also be disposed on the outer sidewall of the pivot inner ring 110 . 1B, after assembly, the pivot inner ring 110 rotates in the pivot outer ring 120. When the inner ring split groove 112 and the outer ring split groove 122 are aligned with each other, an electrical connection element, such as a flexible circuit board, can be made Or electric wires (not shown), pass through the inner ring split groove 112 and the outer ring split groove 122, and are arranged in the pivot assembly.

However, in another embodiment, the pivot outer ring and the pivot inner ring can also be assembled in different ways. Referring to Fig. 2A, it shows an exploded view of another embodiment of the pivot assembly of the present invention, which has different shapes of inner ring fixing parts and outer ring fixing parts from the embodiments of Fig. 1A and Fig. 2A, and adopts different assembly Way. The lower edge 214 of the pivot inner ring 210 has an annular groove 213 , and the upper edge 224 of the pivot outer ring 220 has a plurality of hooks 223 . Wherein, the aforementioned annular groove 213 and hook 223 may have different forms, for example, an annular hook is used instead of the hook 223, and the positions of the annular groove 213 and the hook 223 may be interchanged. Referring to FIG. 2B , an assembled view of the FIG. 2A embodiment of the pivot assembly of the present invention is shown. During assembly, the above-mentioned hook 223 is fitted into the annular groove 213 , so that the lower edge 214 of the pivot inner ring 210 is rotatably mounted on the upper edge 224 of the pivot outer ring 220 . Wherein, the pivot inner ring 210 can rotate about the axis B-B relative to the pivot outer ring 220 (as shown in FIG. 2B ).

Similarly, when the pivot inner ring 210 is rotated relative to the pivot outer ring 220, and the inner ring split groove 212 and the outer ring split groove 222 are aligned with each other, an electrical connection element, such as a flexible circuit board or an electric wire ( not shown), pass through the inner ring split groove 212 and the outer ring split groove 222, and are arranged in the pivot assembly. Since more and more electronic devices are light, thin and small, there is an urgent need for a pivot assembly that is highly compatible with the electrical connection element, so that the pivot assembly will not affect the original function of the electrical connection when it moves. It can be seen from the above preferred embodiments of the present invention that the pivot assembly of the present invention can have the following advantages:

Because in the electronic device of the present invention, the electrical connection element passes between the split grooves on the pivot shaft and is placed in the pivot assembly, so the size design of the connection seats at both ends of the electrical connection element does not need to be designed. Accommodate the size of the pivot component itself.

2. It is very simple to place the electrical connection element in the pivot assembly, thus simplifying the existing assembly procedure.

3. Moreover, there is no excessive friction between the pivot assembly and the electrical connection element, thus greatly reducing the chance of the entire electronic device becoming a defective product due to wear of the electrical connection element.
