Description

Technical Field

[0001] This utility model relates to the field of control panels, and more specifically, to a flexible home appliance control display panel. Background Technology

[0002] The display and control functions of existing home appliances typically rely on digital tubes. Digital tubes consist of multiple LED chips packaged into specific character shapes, requiring multiple pins and common terminals. This results in a complex structure, cumbersome manufacturing processes, and a large number of pins that occupy space, making it difficult to meet the demands of product miniaturization trends. Especially in confined spaces or curved surfaces inside appliances, conventional rigid PCB boards and digital tubes cannot be bent and adapted, not only wasting space but also potentially affecting product integration due to installation limitations.

[0003] Flexible PCBs, using polyimide or polyester film as the substrate, have advantages such as good flexibility and small footprint, and are increasingly being used in the field of home appliance display control. For example, by setting LED light-emitting diodes and flexible light-concentrating support plates on flexible PCBs, digital display functions can be achieved by replacing traditional digital tubes, and the flexible structure can adapt to complex spaces such as curved surfaces.

[0004] Chinese Patent Publication No. CN216162924U discloses a flexible display control board for small household appliances, including a flexible PCB board, on which multiple LEDs and LED driver chips electrically connected to the LEDs are arranged in a set character pattern on the flexible PCB board; and a flexible light-concentrating support plate, which is located above the LEDs and has display holes corresponding to the corresponding LEDs. The LEDs can emit light through the display holes to display product operation information.

[0005] However, existing flexible display control boards still have technical defects in terms of insufficient protection during transportation. Flexible PCB boards and flexible light-concentrating support boards lack rigid support during stacking and transportation, and are prone to internal circuit breakage or component detachment due to external pressure or bending (such as LED pin displacement or chip solder joint cracking).

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flexible home appliance control display board.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flexible home appliance control display panel, comprising a flexible panel, the flexible panel comprising a flexible PCB board and a flexible light-concentrating support plate disposed above the flexible PCB board, the flexible PCB board being provided with a control chip, an LED light-emitting diode and an LED driver chip, the flexible light-concentrating support plate having display holes corresponding to the LED light-emitting diodes, and a plurality of flexible magnetic components being detachably connected to the edge of the flexible light-concentrating support plate near the flexible PCB board, and the flexible magnetic components being located on the outer side of the flexible PCB board, the flexible magnetic components being flexible magnetic rubber strips or bendable ferrite magnetic strips, the thickness of which is consistent with the thickness of the flexible PCB board and is intermittently arranged along the edge contour of the flexible light-concentrating support plate, when the flexible panels are stacked, adjacent flexible magnetic components are attracted and engaged by magnetic poles.

[0009] The present invention is further configured such that: the flexible magnetic component is fixed to the four corners of the flexible light-concentrating support plate by adhesive, and an easy-tear tab is integrally formed on the flexible magnetic component located outside the outline of the flexible light-concentrating support plate, so that the flexible magnetic component and the flexible light-concentrating support plate can be separated by tearing the easy-tear tab.

[0010] The present invention is further configured such that: the outer surface of the flexible light-concentrating support plate is coated with an anti-fingerprint coating, wherein the anti-fingerprint coating is a nano-silica coating or a fluorinated coating, and the thickness is 0.5-2μm.

[0011] The present invention is further configured such that: the outer surface of the flexible light-concentrating support plate is covered with a peelable protective soft film, the protective soft film being a transparent PET film or polyethylene film, which is bonded to the flexible light-concentrating support plate by a low-viscosity adhesive, and the light transmittance of the protective soft film being ≥90%, allowing the LED light-emitting diodes to display operating information normally through the display hole.

[0012] The present invention is further configured such that: a terminal is provided at the tail of the flexible PCB board, and one side of the terminal is covered with flexible protective cotton, the thickness of which is 0.2-1mm.

[0013] The present invention is further configured such that the magnetic field strength of the flexible magnetic component is 100-200mT.

[0014] In summary, this utility model has the following beneficial effects: Through the magnetic attraction effect of the flexible magnetic components, flexible appliance control display panels can be stacked to form a near-rigid whole, solving the problems of flexible panels being easily bent and components being easily collided. Multiple flexible appliance control display panels, after being adsorbed and stacked, can also prevent tipping, scattering, and bending. The magnetic attraction of the flexible magnetic components supports temporary fixation to the metal surface of the appliance, allowing the flexible appliance control display panel to be temporarily fixed to the metal surface of the appliance during installation. This avoids damage to the flexible appliance control display panel caused by haphazard placement during assembly and improves assembly efficiency. The material and thickness of the flexible magnetic components are compatible with the original flexible structure depth, without introducing additional rigid components, ensuring that the "bendable" characteristic is not affected.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] A flexible home appliance control display board, its core lies in the innovative design of a detachable flexible magnetic component 4, which improves the transportation protection and installation convenience of the flexible home appliance control display board, while also taking into account surface protection and circuit safety, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a flexible panel 1, which is composed of a flexible PCB board 2 made of polyimide substrate and a flexible light-concentrating support plate 3 made of compressed sponge material. The compressed sponge has excellent flexibility and bendability, with an elongation at break of 150%-200%, and can withstand bending with a radius of ≥10mm without damage, perfectly matching the bending characteristics of the flexible PCB board 2. The flexible light-concentrating support plate 3 made of compressed sponge material can bend synchronously with the flexible PCB board 2, avoiding stress concentration caused by differences in material rigidity, thereby reducing the risk of lead breakage or solder joint cracking of LED light-emitting diodes due to compression. The flexible PCB board 2 integrates a control chip, LED light-emitting diodes, and LED driver chips. The flexible light-concentrating support plate 3 has corresponding openings for character and operation status display holes 9. The operation methods of the control chip, LED light-emitting diodes, and LED driver chips are well known to those skilled in the art, and therefore will not be described in detail here. Four flexible magnetic components 4 are detachably connected to the four corners of the flexible light-concentrating support plate 3 near the edge of the flexible PCB board 2 by acrylic adhesive. Each flexible magnetic component 4 is a flexible magnetic rubber strip with a thickness of 0.5mm and the same thickness as the PCB board (a bendable ferrite magnetic strip can also be used in other embodiments). The flexible magnetic components 4 are located on the outside of the flexible PCB board 2 and are intermittently distributed along the edge contour of the flexible light-concentrating support plate 3. The magnetic field strength is 150mT. An easy-tear tab 5 is integrally formed on its outside. The exposed length of the easy-tear tab 5 is 5mm, which is convenient for tearing and separating with one hand during installation.

[0022] The magnetic attraction of the flexible magnetic component 4 allows the flexible appliance control display panels to be stacked into a near-rigid whole, solving the problems of the flexible panel 1 being easily bent and components being easily collided. An independent flexible appliance control display panel is similar to a single sheet of paper, which is extremely easy to bend and damage due to external forces. However, the whole formed by multiple flexible appliance control display panels adsorbing and stacking together is no longer easy to bend. Moreover, the adsorption and stacking of multiple flexible appliance control display panels can also play a role in preventing tipping and scattering. Furthermore, the magnetic attraction of the flexible magnetic component 4 supports temporary fixation to the metal surface of the appliance, allowing the flexible appliance control display panel to be temporarily fixed to the metal surface of the appliance during installation. This can avoid damage to the flexible appliance control display panel caused by haphazard placement during assembly and improve assembly efficiency. Finally, the material and thickness of the flexible magnetic component 4 are adapted to the depth of the original flexible structure, without introducing additional rigid components, ensuring that the "bendable" characteristic is not affected.

[0023] The magnetic field strength of the flexible magnetic component 4 is limited to 100-200mT. In this embodiment, 150mT is used, which can provide sufficient adsorption force to ensure that the stacked components are not tipped over or scattered. This is especially suitable for automated warehousing and transportation. The manual separation force is ≤10N, which can be operated with one hand. The flexible magnetic component 4 is fixed to the four corners of the flexible light-concentrating support plate 3 with acrylic adhesive. The position of the four corners can improve the stability of the flexible home appliance control display panels after they are mutually attracted. When installing the flexible home appliance control display panel, the flexible magnetic component 4 can be separated by pinching the easy-tear tab 5 with your fingers and applying vertical pulling force, so as to avoid magnetic materials from getting close to the circuit and causing magnetic interference to the control chip.

[0024] Furthermore, such as Figure 2 As shown, the outer surface of the flexible light-concentrating support plate 3 is coated with a 1μm thick nano-silica coating (a fluorinated coating may also be used in some embodiments). The hydrophobic and oleophobic properties reduce fingerprint residue and improve the cleanliness of the appearance of home appliances, which is especially suitable for high-frequency contact scenarios such as kitchen appliances.

[0025] Furthermore, such as Figure 2 As shown, the outer surface of the flexible light-concentrating support plate 3 is covered with a peelable protective film 6. The protective film 6 is a transparent PET film with a light transmittance of 92% (a polyethylene film may also be used in some embodiments). It is attached to the outer surface of the flexible light-concentrating support plate 3 with a low-viscosity silicone adhesive. During transportation, it can absorb friction and impact and prevent surface scratches. The light transmittance of the protective film 6 also allows the LED light-emitting diodes to display operating information normally through the display hole 9. This allows some users to use the control panel normally without removing the protective film 6, for the sake of protecting the control panel.

[0026] like Figure 1 and Figure 2 As shown, a terminal 7 is provided at the tail of the flexible PCB board 2. One side of the terminal 7 is covered with flexible protective cotton 8. The thickness of the flexible protective cotton 8 is 0.8mm, which can effectively protect the wire harness of the terminal 7 and prevent damage during transportation and installation that could cause the wiring circuit to break.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
