Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrical appliance accessories, in particular to a panel outer frame. BACKGROUND

[0002] The panel outer frame is a supporting structure for mounting and fixing a functional part to a wall surface, the functional part is mounted in the mounting frame of the panel outer frame, and the panel outer frame is mounted and fixed to the wall surface by means of screws or the like.

[0003] As shown in Figure 1 , the wall switch comprises a switch module, a substantially rectangular panel outer frame, and an outer key.

[0004] When installing the wall switch, the panel outer frame usually needs to be fixed on the wall or the recess box by means of screws, as shown in Figure 2a , Figure 2b , the area of the panel outer frame is mainly divided into area 201, area 202, and area 203. During the process of applying pre-tightening force to the screws, each area will receive different degrees of energy, so that each area will produce different degrees of deformation.

[0005] Area 201 receives most of the energy, and the excess energy passes through the symmetrical area 202 and extends to area 203. Experiments show that the deformation value of area 203 is the largest, and the deformation values of area 202 and area 201 are relatively small.

[0006] During the installation of the wall switch, due to the excessive deformation of the edge frame of the bearing area 203, the panel outer frame 2 will interfere with the outer key 3, causing the outer key to be stuck when it is tilted, and even unable to be used. SUMMARY

[0007] The purpose of the present application is to solve the above-mentioned problems existing in the prior art, and to provide a structure for reducing the deformation of the panel outer frame, so as to solve the problem that the excessive deformation of the panel outer frame affects the use of the product during installation.

[0008] The present application can be implemented by one or more of the following technical solutions:

[0009] Technical solution 1: A panel outer frame, which is substantially rectangular in outline, comprises

[0010] a first backing plate 2 serving as a mounting surface, the first backing plate 2 comprising

[0011] a symmetrical first frame 21 for receiving mechanical energy W1 transmitted from area 201;

[0012] The second frame 22 is symmetrical to the first frame 21 and is connected to the first frame 21 through the corner area 202 to absorb the mechanical energy W2 from the first frame 21; wherein the length of the second frame 22 is obviously greater than the length of the first frame 21;

[0013] The second frame 22 comprises

[0014] a first component 221 for constituting a first absorption path of the mechanical energy W2; and

[0015] a second component 222 for constituting a second absorption path of the mechanical energy W2; wherein the surface area of the first component 221 is less than the surface area of the second component 222. The present application makes the mechanical energy converted from the external pressure to be released in different degrees through the path selection of the first component 221 and the second component 222, selectively increases the stress of the partial area of the panel frame, and thus improves the deformation resistance of the partial area.

[0016] In one example, the panel frame further comprises a second lining plate 3 spliced or nested with the first lining plate 2; wherein the second lining plate 3 is the same as or different from the first lining plate 2 in shape.

[0017] One effect of this is that the first lining plate 2 and the second lining plate 3 support each other, and thus the stress of the panel frame can be improved.

[0018] Furthermore, the second lining plate 3 is made of metal. One effect of this is that the support force of the lining plate made of metal is stronger than that of the lining plate made of plastic, and thus the stress of the panel frame can be further improved through the lining plate made of metal.

[0019] On this basis, the second lining plate 3 further comprises a plurality of wrinkle parts formed on the surface to absorb at least part of the mechanical energy W1. One effect of this is that the design of the wrinkle parts can diffuse the external pressure, and thus the stress of the panel frame can be further improved.

[0020] In another example, a third component 223 is formed between the first component 221 and the second component 222 to absorb at least part of the mechanical energy W2.

[0021] Furthermore, the third component further comprises a sheet structure (2231) with a preset thickness symmetrically extending towards the first frame 21.

[0022] On this basis, the preset thickness of the sheet structure 2231 is less than the average thickness of the first lining plate 2.

[0023] One effect is that the third component can release the mechanical energy converted by the external pressure through the path, thereby improving the stress of the panel frame, and can diversify the design of the panel frame.

[0024] Technical solution 2: A panel frame, which is substantially rectangular in outline, comprises

[0025] The first backing plate 2 as the mounting surface comprises

[0026] The symmetrical first frame 21 is used to receive the mechanical energy W1 transferred by the area 201;

[0027] The symmetrical second frame 22 extends with the first frame 21 through the corner edge area 202, and is used to absorb at least part of the mechanical energy W2 transferred from the first frame 21;

[0028] The panel frame further comprises a third frame connected with the second frame 22 and arranged in parallel with the first frame 21, and used to absorb the mechanical energy W2 transferred from the second frame 22.

[0029] One effect is that when the length of the panel frame itself is too long, the third frame can support the first frame 21 and the second frame 22, and release the external pressure through the path, thereby improving the stress of the panel frame.

[0030] The second frame 22 comprises

[0031] The first component 221 is used to form the first path for absorbing the mechanical energy W2; and

[0032] The second component 222 is used to form the second path for absorbing the mechanical energy W2; wherein the surface area of the first component 221 is smaller than that of the second component 222.

[0033] One effect is that the first component 221 and the second component 222 can release the mechanical energy converted by the external pressure through the path selection to different degrees, selectively improve the stress of the partial area of the panel frame, and thereby improve the deformation resistance of the partial area.

[0034] In one example, the third component 223 is formed between the first component 221 and the second component 222, and is used to absorb at least part of the energy W2.

[0035] Further, the third component further comprises a sheet structure 2231 with a preset thickness symmetrically extending towards the first frame 21.

[0036] Further, the preset thickness of the sheet structure 2231 is less than the average thickness of the first backboard 2.

[0037] One effect of this is that the third component can, on the one hand, cause the mechanical energy converted by the external pressure to be released through the path, thereby improving the stress of the panel frame, and on the other hand, can make the panel frame design more diversified.

[0038] In another example, the panel frame further comprises a second backboard 3 spliced or nested with the first backboard 2. The second backboard 3 is the same or different in shape from the first backboard 2. One effect of this is that the first backboard 2 and the second backboard 3 support each other, thereby improving the stress of the panel frame.

[0039] Further, the second backboard 3 is made of metal. One effect of this is that the support of the backboard made of metal is stronger than that of the backboard made of plastic, and thus the stress of the panel frame can be further improved by the backboard made of metal.

[0040] Further, the second backboard 3 comprises a plurality of wrinkle portions formed on the surface, for absorbing at least part of the mechanical energy W1. One effect of this is that the design of the wrinkle portions can diffuse the external pressure, thereby further improving the stress of the panel frame.

[0041] The present application makes the frame structure of the panel frame less deformed or not deformed, thereby ensuring the cooperation gap between the panel frame and the external key. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical scheme and advantages of the present application more clear, the following is a specific embodiment of the present application and a further description of the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0054] If an object is subjected to a force and a displacement occurs in the direction of the force, we say that the force does work on the object. How much work is done, how much energy is converted. When the force object makes the force object produce displacement, the displacement is deformation, by the formula

[0055]

[0056] Where Δl represents the deformation amount of the area 203, l is the initial inherent length of the area 203, E is the deformation modulus, EA is the compression stiffness, F represents the force applied on the local surface of the panel during screw installation, ΔW represents the mechanical energy transferred to the local surface of the panel during each screw rotation, S represents the local deformation amount of the panel when absorbing the mechanical energy ΔW, and θ represents the collimation offset angle of screw installation. It should be understood that when the force F is continuously applied to the area 201 to apply a rotation force, the energy transferred due to the contact between the threads is continuously absorbed by the area 201, and when the mechanical energy ΔW continuously input is sufficiently absorbed by the area 201 to cause the area 201 to deform, the subsequent applied energy ΔW will be released to the surroundings of the area 201. Therefore, it can be known that when the deformation of the area 201 under the action of a certain force F is fixed, i.e., the amount S is a constant, the energy ΔW and the deformation amount Δl are in a linear proportional relationship, i.e., the greater the energy, the greater the deformation of the area 203, and the smaller the energy, the smaller the deformation.

[0057] In the present application, the fastener such as a screw needs to exert a certain force in the installation hole, and in this process, kinetic energy is converted into internal energy, and energy is involved, that is, the force produces displacement, and the outer frame of the panel is partially displaced in the direction of the force, that is, deformation is generated.

[0058] Example 1

[0059] The outer frame of the panel can have a structure as shown in Figure 3a , Figure 3b but is not limited to the structure shown in the figure.

[0060] As shown in Figure 3a , Figure 3b , an outer frame of a panel, which is generally rectangular in outline, comprises a first backing plate 2 as a mounting surface, the first backing plate 2 comprises a symmetrical first frame 21 for receiving mechanical energy W1 transmitted by the area 201; a symmetrical second frame 22 extends to each other through the corner area 202 with the first frame 21, for absorbing mechanical energy W2 transmitted from the first frame 21; wherein the length of the second frame 22 is significantly greater than that of the first frame 21; the second frame 22 comprises a first component 221 for constituting a first path of mechanical energy absorption; and a second component 222 for constituting a second path of mechanical energy absorption; wherein the surface area of the first component 221 is smaller than that of the second component 222.

[0061] In the present embodiment, the structure of the first component 221 and the second component 222 is as shown in Figure 3a , a gap is formed between the first component 221 and the second component 222, which is located on the first backing plate 2 and above the second backing plate 3. The gap can be U-shaped or rectangular. The gap can be designed as a completely hollow structure, or a third component 223 can be formed for absorbing at least part of the mechanical energy W2. For example, as shown in Figure 3b , on the basis of the hollow gap, the third component 223 can be a single piece of sheet structure arranged in the middle of the gap, dividing the gap into two gap spaces, or the third component 223 can be a plurality of single piece of sheet structure arranged in the gap, dividing the gap into a plurality of gap spaces.

[0062] For another example, the third component 223 can further comprise a sheet structure 2231 having a predetermined thickness symmetrically extending towards the first frame 21. The sheet structure 2231 can partially cover the gap or completely cover the gap.

[0063] In the present embodiment, the predetermined thickness of the third component 223 and the sheet structure 2231 thereof is less than the average thickness of the above-mentioned first backing plate 2.

[0064] Preferably, in the present embodiment, the gap is preferably designed as a completely hollow structure.

[0065] In the embodiment, as shown in Figure 3a The first frame 21, the second frame 22, the area 201, and the area 202 are symmetrically arranged. Figure 3a The parts are not repeatedly labeled in the

[0066] As shown in Figure 4 The panel frame further comprises a second lining plate 3 spliced or nested with the first lining plate 2, wherein the second lining plate 3 is the same or different in shape from the first lining plate 2. The splicing or nesting form can be various. In the embodiment, the second lining plate 3 is nested into the first lining plate 2. The first lining plate 2 is provided with a positioning column 23, and the second lining plate 3 is provided with a positioning hole 33 corresponding to the positioning column 23. The positioning column 23 and the positioning hole 33 are cooperatively installed and positioned. In order to make the first lining plate 2 and the second lining plate 3 cooperate more closely, the first lining plate 2 is further provided with a buckle 24, and the second lining plate 3 is provided with a fixing structure 34 matched with the buckle. Alternatively, the first lining plate 2 and the second lining plate 3 are bonded by an adhesive such as glue.

[0067] In the embodiment, the first lining plate 2 is provided with a mounting hole 25, and the second lining plate is provided with a mounting hole 35 corresponding in position and shape to the mounting hole 25. In the embodiment, a screw or a rivet is used to fix the panel frame to a wall surface or a secret box through the mounting holes.

[0068] In the embodiment, as shown in Figure 4 The positioning column 23, the positioning hole 33, the mounting hole 25, the mounting hole 35, the buckle 24, and the fixing structure 34 matched with the buckle are symmetrically arranged. Figure 4 The parts are not repeatedly labeled in the

[0069] Generally, the second lining plate 3 can be of a metal material or a plastic material. Because the metal material has rigidity, it can more effectively support the first lining plate. Therefore, in the embodiment, the second lining plate 3 of the metal material is preferentially selected.

[0070] The second lining plate 3 can be of a flat structure or a structure with a wrinkle part. The structure with the wrinkle part is more conducive to absorbing mechanical energy W1. Therefore, in the embodiment, the second lining plate 3 with the structure of the surface having a plurality of wrinkle parts is preferentially used.

[0071] In the present application, the fastener such as a screw needs to exert a certain force in the installation hole to generate mechanical energy W, the area 201 of the panel outer frame generates and releases the first mechanical energy W1 due to the action of the torque force, according to the law of conservation of mechanical energy, the corner area 202 absorbs the mechanical energy W1 transmitted by the area 201, and transmits the excess mechanical energy W2 to the area 203, the area 203 is divided into two parts, area 2031 and area 2032, because the surface area of area 2031 is smaller than that of area 2032, due to the inertia of molecular motion in the process of mechanical energy transmission, most of the excess mechanical energy W2 transmitted by the corner area 202 will be transmitted to the area 2032 with larger surface area, and the mechanical energy W2 absorbed by the area 2031 with smaller surface area will be relatively small.

[0072] The first frame 21 bearing the mechanical energy of the area 201 and the mechanical energy of the area 202 is in a short structure, and has strong mechanical energy bearing capacity, the second frame bearing the mechanical energy of the area 203 is in an elongated structure, and has weak mechanical energy bearing capacity, the second frame is divided into a first component of the first mechanical energy absorption path and a second component of the second mechanical energy absorption path, in order to ensure that the edge structure of the panel outer frame has little or no deformation in cooperation with the outer key, that is, in the present application, because the surface area of the first component 221 of the mechanical energy of the area 2031 is smaller than that of the second component 222 of the mechanical energy of the area 2032, the mechanical energy W2 absorbed by the first component 221 is also less, and the deformation amount is also smaller.

[0073] Experimental data show that, as shown in Table 1, when the gap is all hollow structure, the total deformation amount is 0, and the effect is best.
