Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to an assembly structure for the control components of an electrical panel. Background Technology
[0002] For electrical appliances controlled by knobs (such as for temperature and time), the outer casing is typically made of highly malleable plastics like ABS or PP. This allows for the use of pre-drilled holes in the mold to accommodate control components (such as knobs, controllers, and indicator lights). However, due to factors like the internal structure, wall thickness, and weight of the casing, injection molding defects such as color differences and deformation patterns are prone to occur. Furthermore, defective injection molded parts cannot be repaired, significantly impacting product costs. Additionally, control indicator lights (such as heating indicator lights) in these appliances are usually located near the knobs, assembled using clips or screws molded internally into the outer casing. This not only complicates the mold structure but also increases processing costs. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an assembly structure for the control components of an electrical panel. This utility model adopts a metal stamping panel and assembly plate structure, which is stable in forming and utilizes cost control. At the same time, it can quickly and stably assemble controllers, knobs and other control components, ensuring assembly effect.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] An assembly structure for a control component of an electrical panel includes a control knob cover and an indicator light exposed on the front of the panel, a knob shaft type electric controller disposed on the back of the panel, and an assembly plate supporting and connecting the above-mentioned mechanisms. The assembly plate includes an integrally connected light mounting part and a control part, and the assembly plate is disposed against the back of the panel.
[0006] After the mounting bolt passes through the mounting holes on the control unit and the panel, it is screwed into the pre-set screw holes on the bracket of the electronic controller.
[0007] The lamp mounting section has several buckles on the side facing away from the panel. Adjacent side ends of the buckles are integrally equipped with limiting wedges. The lampshade of the indicator light is fitted with the adjacent buckles with a gap, and the end face of the lampshade passes through the lamp mounting section and a pre-set through hole on the panel, exposing it to the outside. When the indicator light cover is inserted into the through hole, the gap between the limiting wedges of the corresponding buckles in the lamp mounting section is smaller than that of the lampshade, causing the buckles to be pushed open by the lampshade. After the lampshade is in place, it no longer presses against the limiting wedges, so the buckles return to their original position and are limited by the limiting wedges to prevent the indicator light from retracting.
[0008] Preferably, the panel has an inner groove for assembling the control knob cover, and the shaft of the knob shaft type electric controller passes through the control part and the shaft hole preset on the inner groove and is then assembled with the control knob cover. The mounting hole is provided on the inner groove.
[0009] Preferably, a bending transition section is provided between the lamp mounting section and the control section, and a reinforcing rib is provided on the bending transition section of the lamp mounting section.
[0010] Preferably, the adjustment part is further provided with an umbrella-shaped spring clip on the side facing the panel, and the inner groove is pre-set with a limiting hole for assembling the umbrella-shaped spring clip. The umbrella-shaped spring clip can be quickly assembled with the limiting hole, thereby realizing a quick and accurate connection between the assembly plate and the panel.
[0011] Preferably, the control unit has a limiting protrusion integrally provided on the outer circumference of the mounting hole on the side facing away from the panel, and several of the limiting protrusions are clearance-fitted with the bracket of the electronic controller. The limiting protrusions define the relative position of the electronic controller bracket and the panel, and achieve concentricity of the shaft and the shaft hole in the groove of the panel.
[0012] Preferably, a limiting rib plate that is interference-fitted with the electronic controller is integrally extended along the longitudinal edge on the opposite side of the control unit. The position and size of the limiting rib plate can effectively fit the shape of the electronic controller, reducing the risk of the electronic controller becoming loose.
[0013] Preferably, both the panel and the mounting plate are integrally die-cast.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] 1) The assembly panel, through its optimized integrated structure, takes into account the indicator lights, the rotary shaft-type electronic controller, and the fixed assembly effect between itself and the panel.
[0016] 2) The panel is made of cold-rolled steel sheet and processed by punching, pressing, and spraying, which is more cost-effective than plastic materials and significantly reduces defects such as color difference and deformation;
[0017] 3) The panel adopts a pressed design with an inner groove and punched holes, which improves the flatness of the assembly of the knobs, indicator lights and the panel. At the same time, the bending transition part of the assembly plate not only avoids the inner groove, but also improves its own strength with the help of reinforcing ribs. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this 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 specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0028] like Figure 1-9 As shown, an assembly structure for the control components of an electrical panel includes a control knob cover 5 and an indicator light 3 exposed on the front side of the panel 1, a knob shaft type electronic controller 4 disposed on the back side of the panel 1, and an assembly plate 2 supporting and connecting the above-mentioned mechanisms.
[0029] The panel 1 has an inner groove 51 for assembling the control knob cover 5;
[0030] The assembly plate 2 includes an integrally connected lamp mounting part 21 and control part 22. A bending transition part 23 with a clearance inner groove 51 is provided between the lamp mounting part 21 and the control part 22. A reinforcing rib 24 is provided on the bending transition part 23. The assembly plate 2 is disposed against the back of the panel.
[0031] The lamp mounting part 21 is provided with several buckles 26 on the side facing away from the panel 1. The side ends of the buckles 26 are integrally provided with limiting wedges 261. The lamp cover of the indicator light 3 is fitted with the adjacent buckles 26 with a gap, and the end face of the lamp cover is exposed to the outside through the lamp mounting part 21 and the preset through hole 31 on the panel 1.
[0032] The shaft 41 of the rotary shaft type electronic controller 4 passes through the shaft hole 411 preset on the control part 22 and the inner groove 51 and is then assembled with the control knob cover 5.
[0033] After the mounting bolt 6 passes through the mounting hole 61 opened on the control part 22 and the inner groove 51, it is screwed into the screw hole 43 pre-set on the bracket 42 of the knob shaft type electric controller 4.
[0034] The control unit 22 is also provided with an umbrella-shaped spring buckle 25 on the side facing the panel 1, and the inner groove 51 is provided with a limiting hole 251 for assembling the umbrella-shaped spring buckle 25.
[0035] The control unit 22 is provided with a limiting protrusion 27 on the outer circumference of the mounting hole 61 on the side facing away from the panel. Several of the limiting protrusions 27 are in clearance fit with the side 271 of the bracket 42 of the knob shaft type electric controller 4.
[0036] On the opposite side of the control unit 22, a limiting rib plate 28 is integrally extended at the length edge to interfere with the knob shaft type electric controller 4.
[0037] Taking commercially available kitchen water heaters as an example:
[0038] Both panel 1 and assembly plate 2 are made of cold-rolled steel and formed by punching, pressing and spraying process.
[0039] During assembly, the umbrella-shaped spring clip 25 of the assembly plate 2 is first inserted into the limiting hole 251 of the inner groove 51 to complete the initial assembly of the assembly plate 2 and the panel 1.
[0040] Then install the heating indicator light (i.e., indicator light 3). When the lamp cover of the heating indicator light enters the through hole 31, the gap of the limiting wedge 261 of the corresponding buckle of the lamp mounting part is smaller than that of the lamp cover and drives the buckle 26 to be opened by the lamp cover. After the lamp cover is installed in place, the lamp cover no longer squeezes the limiting wedge 261, so the buckle 26 returns to its original position and limits the heating indicator light through the limiting wedge 261 to prevent it from moving backward.
[0041] Then install the thermostat (i.e., the rotary knob type electric controller 4). First, pass the mounting bolt 6 through the inner groove 51 and the mounting hole 61 opened on the control part 22. Then, align the pre-set screw hole 43 on the thermostat bracket 42 with the mounting bolt 6 and screw it in. After the thermostat is installed in place, its outer wall is completely covered by the limiting rib plate 28, and at the same time, the limiting protrusion 27 is engaged with the outside of the bracket, thus providing double limiting for the thermostat.
[0042] Finally, install the temperature control knob cover (i.e., the control knob cover 5) and engage it with the shaft 41 exposed outside the inner groove 51.
