Detailed Description

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings illustrate, by way of example, specific embodiments in which the invention may be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments according to the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

The supporting device 100 in the related art will be described in detail with reference to fig. 1. Fig. 1 shows a schematic view of a prior art support device 100 for a stacked arrangement of two printed circuit boards. As can be seen from fig. 1, such a supporting device 100 includes an upper supporting structure 110 and a lower supporting structure 120, and the two supporting structures 110 and 120 can be respectively used for supporting a printed circuit board, so that the supporting device 100 can indeed achieve the purpose of supporting two printed circuit boards, and can enhance the rigidity of the supported printed circuit boards. However, since the printed circuit board supported by the lower supporting structure 120 is completely hidden by the upper supporting structure 110, the installation and the repair of the printed circuit board supported by the lower supporting structure 120 become inconvenient. Furthermore, the four mounting legs 130 of the support device 100 are fixedly arranged, so that such a support device 100 can only be mounted on a planar structure.

In order to solve the above technical problem, that is, the technical problem of mutual shielding between different printed circuit boards, the inventor of the present invention thinks of using the main body of the plate-shaped structure to complete the supporting among the technical solutions according to the present invention, thereby solving the problem of mutual shielding. In summary, although the existing supporting device for stiffening the rigidity of the pcb employs a stacked arrangement, which can stiffen the rigidity of the pcb and reduce the occupied area of the pcb, the supporting device can make the maintenance and debugging more difficult due to the mutual shielding. To these technical problems, the inventor of the present invention provides a technical solution that can not shield each other in the present case, thereby facilitating maintenance and debugging.

The supporting device disclosed according to the present invention will be described in detail below with the aid of the embodiment of fig. 2 to 8.

Furthermore, the proposed supporting device 200 further comprises four fixing members 230, a first end of the fixing member 230 is configured to be connected with the main body 210 to realize the connection of the fixing member 230 relative to the main body 210, and a second end of the fixing member 230 opposite to the first end is configured to be fixed to a fixing member (not shown in fig. 2) to which the supporting device is to be fixed. In this manner, the printed circuit boards are supported by the plate-shaped body 210 so as not to be overlapped with each other, facilitating maintenance and debugging.

In the embodiment shown in fig. 2, the body 210 is configured as a sheet metal part comprising two flat portions at a first angle, namely a left plate-like portion 211 and a right plate-like portion 213. Here, the first angle can be changed within a range of 20 degrees to 180 degrees, for example, and a specific value of the angle can be adapted according to a specific size of a space accommodating the supporting device 200 and the corresponding printed circuit board, thereby improving an applicable scene according to the supporting device 200 of the present invention.

Further, as can be seen from fig. 2, the joint between the left plate-shaped portion 211 and the right plate-shaped portion 213 of the main body 210 may be made of a metal material having relatively good ductility, so that the included angle between the left plate-shaped portion 211 and the right plate-shaped portion 213 of the main body 210 can be adjusted according to the size of the space in which the main body is installed. Specifically, when the mounted position is narrow but the height is sufficient, for example, the first angle can be set to a small value; in contrast, when the mounted position is wide but the height is insufficient, for example, the first angle can be set to a large value.

Accordingly, fig. 6 shows a schematic view of the support device 300 according to fig. 3 at a smaller angle, while fig. 7 shows a schematic view of the support device 300 according to fig. 3 at a larger angle. The angle shown in fig. 6 is here about 20 degrees, whereas the angle shown in fig. 7 is substantially 180 degrees, i.e. when the first plate-like part 311 and the second plate-like part 313 are located substantially in the same plane. In other words, with the help of the supporting device 300 according to the present disclosure, the printed circuit boards used in pairs can be turned and fixed within a range of 20 ° to 180 °, thereby avoiding upper and lower lamination layers, and the layout in the horizontal direction has a certain flexibility.
