Description

Technical Field

[0001] The utility model belongs to the technical field of flexible circuit boards, and more specifically, it relates to a flexible circuit board strengthening element and a physiotherapy appliance. Background Art

[0002] For physiotherapy appliances using infrared lamps, such as physiotherapy belts, etc., after the lamp beads are welded and fixed on a PCB flexible board (i.e., a flexible circuit board), an elastic covering cloth is covered outside the PCB flexible board. Through holes are provided on the inner covering cloth to expose the lamp beads for light emission. However, during use, since the physiotherapy appliance needs to be frequently bent and pulled, it is easy to cause damage to the pins and welding points of the lamp beads, resulting in short circuits and failures of the lamp beads. Moreover, since multiple lamp beads are connected in series, once one lamp bead is damaged, at least one row of lamp beads cannot emit light normally, reducing the durability of the physiotherapy appliance.

[0003] To solve the above problems, we developed a physiotherapy appliance with an application number of CN202321135471.4, which strengthens the flexible circuit board by pasting a reinforcing sheet on the flexible circuit board. However, using this process requires manual gluing and pasting of the reinforcing sheet, with relatively many process flows, a relatively large amount of labor required, and it is not easy to control the pasting quality of the product.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] It should be further noted that the drawings and embodiments of the present utility model mainly describe and explain the concept of the present utility model. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present utility model, those skilled in the art can adopt well-known methods to implement the above specific forms and settings.

[0030] When an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly thereon. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected thereto.

[0031] The orientation terms "inside" and "outside" refer to the inside and outside relative to the contour of each component itself. The terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0032] For the convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" can be used here to describe the spatial positional relationship of a device or feature shown in the drawings with other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings of the device.

The device can also be positioned in other different ways, and corresponding interpretations are made for the spatial relative descriptions used here.

[0033] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0034] Now, the flexible circuit board strengthening element and the physiotherapy appliance provided by the present utility model will be described.

[0035] Such as Figure 1 and Figure 2As shown in the figure, the first embodiment of the present utility model provides a flexible circuit board strengthening element, which includes a clamping plate 11 and a back plate 13. The clamping plate 11 is provided with an avoidance structure 12 for avoiding the electronic components 21 on the flexible circuit board 20.

[0037] As Figures 1 to 3 shown, a specific embodiment provided by the present utility model on the basis of the first embodiment is as follows:

[0038] The avoidance structure 12 is an avoidance groove or an avoidance hole to avoid the electronic components 21 on the flexible circuit board 20, so that the clamping plate 11 and the back plate 13 can better clamp the flexible circuit board 20 and reinforce the part of the flexible circuit board 20 where the electronic components 21 are provided.

[0039] The clamping plate 11 and the back plate 13 are fixedly connected through a connecting bridge 14 so as to form a space with a fixed size between the clamping plate 11 and the back plate 13 for accommodating the flexible circuit board 20. This is also convenient for the production of the entire strengthening element, conducive to reducing production costs, and at the same time can ensure the clamping and fixing of the flexible circuit board 20.

[0040] In a specific embodiment, the clamping plate 11, the back plate 13 and the connecting bridge 14 are integrally formed plastic components; the distance between the clamping plate 11 and the back plate 13 is equal to or less than the thickness of the flexible circuit board 20.

[0041] The thickness of the clamping plate 11 is less than that of the back plate 13 so that the clamping plate can produce slight deformation during installation, which is convenient for clamping the entire strengthening element on the flexible circuit board 20.

[0042] In a specific embodiment, both the clamping plate 11 and the back plate 13 are square plates, the avoidance structure 12 is a square groove, and chamfers are provided at the edges of the back plate 13 to avoid scratching the flexible circuit board 20 and facilitate production.

[0043] Soft rubber layers are provided on both opposite sides of the splint 11 and the back plate 13. The soft rubber layer can be a non-sticky cushion layer to pad on the flexible circuit board 20 for buffering and enhancing the friction between the flexible circuit board 20 and the splint 11 and the back plate 13, reducing the possibility of the strengthening components falling off; the soft rubber layer can also be a sticky glue layer to directly stick the splint 11 and the back plate 13 on the flexible circuit board 20 for fixation, reducing the possibility of the strengthening components falling off.

[0044] As Figure 4 shown, a specific embodiment provided by the present utility model on the basis of the first embodiment is as follows:

[0045] One side of the back plate 13 is connected to the splint 11 through a hinge structure 15, and the other side is connected to the splint 11 through a buckle structure 16.

[0046] A specific embodiment provided by the present utility model on the basis of the first embodiment is as follows:

[0047] Both opposite sides of the back plate 13 are connected to the splint 11 through buckle structures 16.

[0048] As Figure 5 shown, based on the same inventive concept, an embodiment of the present application also provides a physiotherapy device, including a flexible circuit board 20, the above-mentioned flexible circuit board strengthening component, and a cushion layer 30. The flexible circuit board strengthening component is provided on the flexible circuit board 20, and the cushion layer 30 is provided on at least one side of the flexible circuit board 20.

[0049] Compared with the prior art, the physiotherapy device provided in this embodiment can better provide double-sided protection for the pins of the electronic components on the flexible circuit board through the above-mentioned flexible circuit board strengthening component, and the assembly is also relatively convenient, which is beneficial to saving manpower and facilitating the control of product quality.
