Detailed Description
The flat motor with a novel structure provided by the invention is further described in detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 2, a flat motor 1 of a novel structure, which is installed in a mobile device for providing vibration feedback to the mobile device, has a flexible printed circuit board having an external power receiving portion 2 for turning on an external power source, and a conductive copper foil 7 provided in the flexible printed circuit board, and is bent such that the external power receiving portion 2 is located at the bottom of the flat motor 1. Because the external power receiving part 2 is located at the bottom of the flat motor 1, the external power receiving part 2 does not occupy additional installation space, and can be installed and positioned along with the flat motor 1 without separate positioning, thereby reducing installation difficulty and saving installation time. Preferably, the bottom of the flat motor 1 may be circular, the length of the external power connection part 2 is smaller than the diameter of the bottom of the flat motor 1, and the line between the center of the wire outlet 9 of the external power connection part of the bottom of the flat motor 1 and the center of the circle of the bottom of the flat motor 1 is collinear with the center lines of the external positive and negative power connection ends 3 and 4. In addition, the widths of different parts of the conductive copper foil 7 in the flexible printed circuit board can be different, for example, the parts at the curve or arc connection positions can be widened, so that the flexibility of the flexible printed circuit board is improved, and the effect of effectively preventing the flexible printed circuit board from being broken is achieved. The conductive copper foil 7 can be bent, so that the flexibility of the flexible printed circuit board is further enhanced, and a certain effect of reducing radio frequency interference of the mobile phone can be achieved.
Example two
As shown in fig. 3, the flexible printed circuit board of the present invention may have a structure in which the internal positive and negative electrode terminals 5 and 6 of the flexible printed circuit board located inside the motor are located on the upper and lower sides of the long axis 8, respectively, and are symmetrical with respect to the long axis 8 of the flexible printed circuit board, the external positive and negative electrode terminals 3 and 4 of the external electrode terminal 2 are arranged side by side along the long axis 8, and the long axis 8 is collinear with the center line of the external positive and negative electrode terminals 3 and 4. By arranging the external positive and negative electrode terminals 3, 4 along the long axis 8, the space of the external electrode part can be fully utilized, and the contact area of the external electrode pattern can be increased; and, making the internal positive and negative terminals 5, 6 symmetrical with respect to the long axis 8 of the flexible printed circuit board can make the internal electrical pattern better match with the brush soldering. The flexible printed circuit board may be a laminate, i.e. the conductive copper foils 7 respectively connecting the external positive electrode terminal 3 and the external negative electrode terminal 4 are located in different planes, and an insulating layer for avoiding short circuits is provided between the layers. In addition, as shown in fig. 4, by adjusting the length of the conductive copper foil 7, the external positive electrode terminal 3 and the external negative electrode terminal 4 can be exchanged, that is, the original external positive electrode terminal 3 becomes the external negative electrode terminal 4, and the original external negative electrode terminal 4 becomes the external positive electrode terminal 3.
Example III
As shown in fig. 5, the flexible printed circuit board of the present invention may have a structure in which the inner positive and negative electrode terminals 5 and 6 of the flexible printed circuit board located inside the motor are symmetrical with respect to the long axis 8 of the flexible printed circuit board, and the outer positive and negative electrode terminals 3 and 4 of the outer electrode terminal 2 are also symmetrical with respect to the long axis 8. The internal positive and negative electrode terminals 5 and 6 are symmetrical relative to the long axis 8 of the flexible printed circuit board, so that the internal electrode patterns are better matched with the electric brushes in a welding way, and in addition, the external positive and negative electrode terminals 3 and 4 are also symmetrically arranged relative to the long axis 8, so that a laminated structure can be avoided, and the manufacturing cost is saved.
The above-described embodiments are merely examples for clearly illustrating the present invention, and the present invention is not limited to the above-described embodiments. Other variations or modifications of the above description will be apparent to those of ordinary skill in the art, and are intended to be within the scope of the invention.
