[0030] Please refer to Figure 1 , the inverter device 1000 in the embodiment of the present utility model may include the light guide panel structure 100 in the embodiment of the present utility model. The inverter device further includes an inverter housing 200 and a PCB board 300. The inverter housing 200 is specifically connected to the PCB board 300, and the inverter housing 200 is disposed in a fitting manner with the light guide panel structure 100. The light guide panel structure 100 is fixed on the inverter housing 200 to display the inverter status.
[0031] The following specifically elaborates on the light guide panel structure 100, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, the light guide panel structure 100 includes a light guide panel main body 10 and a touch button 20. Among them, a first light guide column 12 is provided on the light guide panel main body 10, and a first groove 11 is provided on the outer circle of the first light guide column 12, that is, the first light guide column 12 is partially filled into the first groove 11. The touch button 20 is sleeved on the first light guide column 12. One end of the touch button 20 is arranged in the first groove 11 and is in contact connection with the first groove 11. The other end of the touch button 20 is arranged higher than the first light guide column 12 and is welded to the PCB board 300.
[0032] Specifically, the first groove 11 is specifically used to position one end of the first light guide column 12. An LED chip is provided on the PCB board 300. The first light guide column 12 is used to guide the light emitted by the LED chip, so that the first light guide column 12 can be used as a light source. The first light guide column 12 is partially arranged in the first groove 11, and the first light guide column 12 protrudes from the first groove 11, that is, the height of the first light guide column 12 is greater than the depth of the first groove 11.
[0033] The touch button 20 can specifically be a spring button. The touch button 20 is sleeved on the first light guide column 12. One end of the touch button 20 is arranged in the first groove 11, and the other end of the touch button 20 protrudes from the first light guide column 12 and is welded to the PCB board 300. And the first light guide column 12 is arranged through the touch button 20 during installation, so that the touch button 20 can enter the first groove 11 and be compressed to provide elasticity for the touch button 20.
[0034] Therefore, in the present utility model, the touch button 20 is sleeved on the first light guide column 12, so that the area for displaying the light in the light guide panel structure 100 can also have the function of a button. Therefore, the touch button 20 can be closely combined with the first light guide column 12, and the first light guide column 12 can directly guide the light to the touch button 20, that is, even if the user is in a low-light environment, the position of the touch button 20 can be clearly identified, achieving the effect of improving the convenience of operating the touch button 20. Moreover, in order to increase the service life of the first light guide column 12, the height of the first light guide column 12 protruding from the first groove 11 should not be too high, and specifically, protruding 1 mm to 5 mm is sufficient.
[0035] And, in the present utility model, by combining the touch button 20 with the first light guide column 12, the effect of effectively utilizing the space and reducing the volume and complexity of the light guide panel structure 100 can be achieved. In addition, in the present utility model, the setting of the first groove 11 can provide better support and stability for the touch button 20, so as to achieve the effect of preventing the displacement or loosening of the touch button 20 during use.
[0036] Further, in a possible implementation, a light - condensing groove 121 is provided on the first light - guiding column 12. Specifically, the light - condensing groove 121 is provided at the end of the first light - guiding column 12. By providing the light - condensing groove 121, the light emitted from the first light - guiding column 12 that diverges in all directions can be gathered, so that the light emitted from the first light - guiding column 12 can be propagated outward from the first light - guiding column 12. This is to achieve the effect of increasing the light - guiding effect of the first light - guiding column 12 and increasing the brightness of the touch button 20.
[0037] Further, the first light - guiding column 12 is a light - guiding column made of PC material or PMMA material. Specifically, the first light - guiding column 12 can be made of a transparent material, specifically PC material or PMMA material. Because the transparent material has a high refractive index, it can further increase the light - guiding effect of the first light - guiding column 12 and increase the brightness of the touch button 20.
[0038] Further, as Figure 3 shown, in the light - guiding panel structure 100, in a possible implementation, in addition to the first light - guiding column 12. The light - guiding panel main body 10 further includes a plurality of second light - guiding columns 13. Each of the second light - guiding columns 13 is arranged at intervals with respect to the first light - guiding column 12, and the plurality of second light - guiding columns 13 are symmetrically arranged with respect to the first light - guiding column 12 and are arranged on both sides of the first light - guiding column 12. An LED chip is provided on the PCB board 300, and the second light - guiding column 13 is used for guiding the light emitted by the LED chip.
[0039] Specifically, both the first light - guiding column 12 and the second light - guiding column 13 are cylindrical light - guiding columns. In the embodiment of the present invention, the first light - guiding column 12 and each of the second light - guiding columns 13 are arranged in a triangular pattern as a whole. In the present invention, by providing the second light - guiding column 13, the overall luminous intensity of the light - guiding panel structure 100 can be improved. In addition, in order to avoid mutual interference between the light beams emitted by the first light - guiding column 12 and the second light - guiding column 13, the distance between the first light - guiding column 12 and the second light - guiding column 13 is greater than 15 mm, so as to avoid mutual interference between the light beams emitted by the first light - guiding column 12 and the second light - guiding column 13.
[0040] Further, as Figure 3 shown, in the light - guiding panel structure 100, in a possible implementation, in addition to the first light - guiding column 12. The light - guiding panel main body 10 further includes a plurality of third light - guiding columns 14. The plurality of third light - guiding columns 14 are arranged at intervals in sequence, are arranged in an arc shape, and are arranged opposite to the first light - guiding column 12. In the present invention, by providing the second light - guiding column 13, the overall luminous intensity of the light - guiding panel structure 100 can be improved.
[0041] Moreover, the second light guide column 13 is rectangular, and the overall shape of each second light guide column 13 is arranged in an arc shape. In this way, the diversity of the light-emitting effect of the light guide panel structure 100 can be achieved.
[0042] Furthermore, in a possible implementation manner, a first spacing groove 15 is provided between two adjacent third light guide columns 14, and the first spacing groove 15 is a V-shaped groove.
[0043] Specifically, a first spacing groove 15 is provided between two adjacent third light guide columns 14. The first spacing groove 15 can be used for a baffle to block the light emitted by each third light guide column 14. The first spacing groove 15 is specifically a V-shaped groove. By setting the tip of the V shape of the first spacing groove, the separation effect in the transition area where the third light guide columns 14 arranged in an arc shape light up from left to right can be avoided. And the first spacing groove 15 being specifically a V-shaped groove structure can also achieve the effect of hiding the first spacing groove 15, thereby improving the aesthetics of the light guide panel structure 100.
[0044] Furthermore, in a possible implementation manner, as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the light guide panel structure 100 further includes a light-shielding plate 30. The light-shielding plate 30 covers the light guide panel and is used to shield the light guide columns on the light guide panel main body 10. Specifically, light-transmitting holes 33 corresponding to the first light guide column 12, the second light guide column 13, and the third light guide column 14 are provided in the light-shielding plate 30.
[0045] Next, the structure of the inverter device 1000 will be further elaborated. In a possible implementation manner, as Figure 6 shown, a film 400 is provided on the inverter housing 200, and the film 400 can protect the surface of the inverter housing 200.
[0046] Furthermore, as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, for the connection method between the light guide panel structure 100 and the PCB board 300, in a possible implementation manner, the light-shielding plate 30 of the light guide panel structure 100 is provided with a plurality of buckles 31 and a plurality of positioning posts 32, and the light-shielding plate 30 is snap-connected to the PCB board 300 through the buckles 31 and the positioning posts 32.
[0047] Specifically, first, the positioning posts 32 on the light-shielding plate 30 are positioned with the positioning posts 32 on the PCB board 300, and then the snap 31 is used to snap the light guide panel structure 100 onto the PCB board 300 to complete the snap connection between the PCB board 300 and the light-shielding plate 30. Moreover, the film 400 area of the inverter housing 200 has a concave structure, which facilitates the accurate pasting position of the film 400. In addition, the light guide panel structure 100 is provided with a sealing ring, and the setting of the sealing ring can achieve the effect of preventing water from entering the inverter.
