It will be appreciated that the material of the case 10 is not limited to metal, the shape of the bottom wall 12 is not limited to rectangle, on one hand, the material of the case 10 is metal, so that the case 10 can be ensured to have enough strength to ensure the service life of the case 10, on the other hand, the shape of the bottom wall 12 is rectangle, the size of the shape of the bottom wall 12 affects the size of the case 10, and the shape rule of the bottom wall 12 is beneficial to reasonably planning the internal space of the case 10, so as to realize that the case 10 accommodates the elements in the electric case 100 in a smaller volume, thereby reducing the manufacturing cost of the electric case 100.

Referring to fig. 1 and 4, the circuit board 20 is disposed in the accommodating space 14, and the circuit board 20 includes an indicator lamp 21, where the indicator lamp 21 is used for emitting light. The positions of the through hole 111, the indicator lamp 21 and the light guide assembly 30 correspond, the light guide assembly 30 is configured to guide the light emitted from the indicator lamp 21 to the through hole 111 for emitting, and when the top wall 11 is connected with the side wall 13 to completely close the accommodating space 14, the light of the indicator lamp 21 can be emitted from the through hole 111 after being guided by the light guide assembly 30, so that a user can determine the state of the electric box 100 by observing whether the through hole 111 of the top wall 11 emits light.

As can be seen from the above, the light guide assembly 30 is located between the through hole 111 and the indicator lamp 21. In one embodiment, the light guide assembly 30 may be directly disposed on the through hole 111, and when the top wall 11 and the side wall 13 are connected to completely enclose the accommodating space 14, the light guide assembly 30 directly contacts the indicator lamp 21, so as to guide the light emitted from the indicator lamp 21 to the through hole 111 for emitting. In another embodiment, the light guide assembly 30 is sleeved on the indicator lamp 21, and the light guide assembly 30 is made of an opaque material, so that only the surface of the light guide assembly 30 contacting the indicator lamp 21 and the through hole 111 is transparent, and when the top wall 11 and the side wall 13 are connected to completely enclose the accommodating space 14, the light guide assembly 30 directly contacts the through hole 111, thereby guiding the light emitted from the indicator lamp 21 to the through hole 111 for emitting.

Referring to fig. 5, the number of the indicator lamps 21 may be plural, for example, 2, 3, 4 and more, and the plurality of indicator lamps 21 are disposed on the circuit board 20 at intervals. In one embodiment, when the number of the indicator lamps 21 is plural, the number of the through holes 111 and the light guide assemblies 30 may be the same as the number of the indicator lamps 21, and each light guide assembly 30 guides the light of the corresponding indicator lamp 21 correspondingly and guides the light to the through hole 111 corresponding to the light to be emitted. In another embodiment, when the number of the indicator lamps 21 is plural, the number of the through holes 111 is the same as the number of the indicator lamps 21, the light guide assembly 30 is one, and the light guide assembly 30 may be provided with openings corresponding to the number of the indicator lamps 21, and each opening corresponds to a single through hole 111, so that the light guide assembly 30 may guide the light of the indicator lamps 21 to be emitted from each opening to a single through hole 111, so that the light is emitted from the through hole 111.

Referring to fig. 1, 4 and 6, the light guide assembly 30 includes a light guide 31 and a first light shielding member 32.

The light guide 31 is disposed in the through hole 111, and the light guide 31 is used for guiding the light emitted from the indicator lamp 21 to be emitted from the through hole 111.

Specifically, the first end of the light guide 31 is disposed in the through hole 111, and the material of the light guide 31 may be Polycarbonate (PC), polymethyl methacrylate (Polymethyl Methacrylate, PMMA), or the like. The light guide 31 has high light-guiding performance, and when the top wall 11 and the side wall 13 are combined to close the accommodating space 14, the second end of the light guide 31 contacts the indicator lamp 21.

When the number of the indication lamps 21 is plural, the number of the through holes 111 and the number of the light guide members 31 are plural, the first ends 311 of the light guide members 31 are disposed in the through holes 111 corresponding to the positions thereof, and when the top wall 11 and the side wall 13 are combined to close the accommodating space 14, the second ends 312 of the light guide members 31 are in contact with the indication lamps 21. Since the light guide 31 has high light guiding performance, the whole light guide 31 emits light when the second end 312 of the light guide 31 contacts the indicator lamp 21. In order to avoid the situation that after one indicator lamp 21 emits light, the light is scattered by one light guide member 31, so that the through holes 111 at the positions corresponding to the indicator lamps 21 which do not emit light also emit light, the first light shielding members 32 are required to be arranged on each light guide member 31, so that when the light emitted by one indicator lamp 21 is guided by the corresponding light guide member 31 of the indicator lamp 21, other light guide members 31 are prevented from being influenced.

Specifically, the material of the first light shielding member 32 is an opaque material. For example, the first shade 32 is a shade foam, a shade adhesive, or the like. The first light shielding member 32 is sleeved on the light guiding member 31 to wrap the light guiding member 31, and the first end 311 of the light guiding member 31 contacting the through hole 111 and the second end 312 contacting the indicator lamp 21 are not sleeved by the first light shielding member 32. When the top wall 11 is combined with the side wall 13 to close the accommodating space 14, the light can be incident into the light guide 31 through the second end 312 of the light guide 31, and the first light shielding member 32 is disposed on the surface of the light guide 31, so that the light will not diverge after entering the light guide 31, and the light can only be emitted through the first end 311 of the light guide 31, and the first end 311 of the light guide 31 contacts the through hole 111, thereby realizing that the light only guides the light of the light guide 31 and is emitted from the through hole 111.

Therefore, the user can judge the state of the electric box 100 by observing the number and the positions of the light rays emitted from the through holes 111 among the through holes 111. For example, there are 4 through holes 111, and if all of the 4 through holes 111 emit light, it indicates that the electric box 100 is in a normal state, and if at least one through hole 111 does not emit light, it indicates that the electric box 100 is abnormal. For another example, 3 indicator lamps 21 emit three kinds of light, i.e., red, green, and white, respectively, and when 1 indicator lamp 21 emits light, the other 2 indicator lamps 21 do not emit light. The user can determine the state of the electric box 100 by determining the color of the light emitted from the through hole 111. For example, the emission of red light is the stop of the electric box 100, the emission of green light is the start of the electric box 100, and the emission of white light is the energization of the electric box 100.

In some embodiments, the first light shielding member 32 may be provided with a plurality of through holes 321, and the plurality of through holes 321 are disposed on the plurality of through holes 111 after the first ends 311 of the plurality of light guiding members 31 are inserted into the through holes 321 of the first light shielding member 32, so that one first light shielding member 32 can directly cover all the light guiding members 31.

Referring to fig. 4 and 5, in some embodiments, the circuit board 20 further includes a second light shielding member 22. The second shading piece 22 is sleeved on the indicator lamp 21, and the height of the second shading piece 22 is higher than that of the indicator lamp 21. The second light shielding member 22 is made of opaque material similar to the first light shielding member 32, and when the circuit board 20 includes the second light shielding member 22, the first light shielding member 32 is only partially sleeved with the light guiding member 31 (as shown in fig. 1).

When the number of the indicator lamps 21 is plural, the second light shielding member 22 may be provided with a plurality of through holes 221, so that each indicator lamp 21 is located in one through hole 221, and since the height of the second light shielding member 22 is higher than that of the indicator lamp 21, the indicator lamp 21 is completely located in the through hole 221 on the second light shielding member 22, when the indicator lamp 21 emits light, the light emitted by the indicator lamp 21 can only be emitted from the opening of the through hole 221.

Specifically, the aperture of the through hole 221 formed in the second light shielding member 22 is larger than the diameter of the light guiding member 31, and when the top wall 11 and the side wall 13 are combined to completely close the accommodating space 14, the first light shielding member 32 and the second light shielding member 22 cooperate to completely cover the light guiding member 31. At this time, the light guide 31 is located in the first light shielding member 32 and the second light shielding member 22, respectively, and since the aperture of the through hole 221 formed in the second light shielding member 22 is larger than the diameter of the light guide 31, it is ensured that the light emitted from the indicator lamp 21 can be guided through the light guide 31 to be emitted from the through hole 111 even when the top wall 11 and the side wall 13 are combined to completely close the accommodating space 14, and errors exist in the corresponding positions of the through hole 111, the light guide 31 and the indicator lamp 21.

Referring to fig. 5 and fig. 6, in one embodiment, a plurality of light guide members 31 may be sleeved by one first light shielding member 32 (as shown in fig. 1), and when the first light shielding member 32 is matched with the second light shielding member 22 to completely sleeve the light guide members 31, the top surface 322 of the first light shielding member 32 may be in contact with the top surface 222 of the second light shielding member 22 to completely sleeve the light guide members 31, or may be a portion of the light guide members 31 not sleeved by the first light shielding member 32, which is just located in the through holes 221 of the second light shielding member 22 and the light guide members 31 are not in direct contact with the second light shielding member 22, and at this time, the top surface 322 of the first light shielding member 32 is just located at the top surface 222 of the second light shielding member 22 to completely sleeve the light guide members 31, so that even if there is an error in the corresponding positions of the through holes 111, the light guide members 31 and the indicator lamps 21, the light emitted from the indicator lamps 21 can still be guided through the light guide members 31.

In another embodiment, the plurality of light guide members 31 may be respectively sleeved with one first light shielding member 32, so when the first light shielding member 32 is matched with the second light shielding member 22 to completely sleeve the light guide members 31, the top surface 322 of the first light shielding member 32 may be in contact with the top surface 222 of the second light shielding member 22 to completely sleeve the light guide members 31, or part of the first light shielding member 32 may be located in the through holes 221 of the second light shielding member 22 to completely sleeve the light guide members 31, so as to ensure that the light emitted by the indicator lamp 21 can still be guided by the light guide members 31 to be emitted from the through holes 111 even if errors exist in the corresponding positions of the through holes 111, the light guide members 31 and the indicator lamp 21.

Referring to fig. 7, in some embodiments, the electric box 100 further includes an indicator light board 40. The indicator light panel 40 is disposed on a surface of the top wall 11 remote from the bottom wall 12.

Specifically, the first surface 113 (the surface far from the bottom wall 12) of the top wall 11 may be provided with a mounting groove 114, the through hole 111 is located in the mounting groove 114, and the indicator light board 40 is disposed in the mounting groove 114, so that the first surface 113 of the top wall 11 is in a flat state.

The indicator light board 40 has good light transmittance, for example, the indicator light board 40 may be an acrylic board, a glass board, a plastic board, etc. The indication lamp panel 40 is disposed in the mounting groove 114 to cover the through hole 111, and since the indication lamp panel 40 has good light transmittance, a user can observe whether light is emitted from the through hole 111 through the indication lamp panel 40. The indicator light board 40 covers the through hole 111, so as to prevent dust, water drops and the like from entering the electric box 100, thereby improving the waterproof and dustproof properties of the electric box 100 and ensuring the service life of the electric box 100.

Referring to fig. 4, in an embodiment, the circuit board 20 further includes a connector 50 and a support plate 60. The connector 50 and the support plate 60 are located in the receiving space 14.

The connecting piece 50 is disposed on the side wall 13 of the electric box 100, the supporting plate 60 is connected with the connecting piece 50, the circuit board 20 is disposed on the supporting plate 60, the supporting plate 60 is parallel to the bottom wall 12 of the electric box 100, at this time, the supporting plate 60 can divide the accommodating space 14 into an upper part and a lower part, and the circuit board 20 is disposed in the accommodating space 14 near the top wall 11.

In one embodiment, the number of connectors 50 may be multiple, such as 2, 3, 4, and more. The plurality of connectors 50 may be disposed on the first sidewall 131, the second sidewall 132, the third sidewall 133, and the fourth sidewall 134 of the electrical box 100, respectively. For example, when the number of the connection members 50 is 2, the connection members 50 may be disposed at the first and third sidewalls 131 and 133, respectively, or the connection members 50 may be disposed at the second and fourth sidewalls 132 and 134, respectively, and the connection members 50 may be disposed at the first and second sidewalls 131 and 132, respectively, or the connection members 50 may be disposed at the first and fourth sidewalls 131 and 134, respectively. For another example, when the number of the connecting members 50 is 3, the connecting members 50 may be disposed on the first side wall 131, the second side wall 132, and the third side wall 133 of the electric box 100, or the connecting members 50 may be disposed on the first side wall 131, the second side wall 132, and the fourth side wall 134, etc., which are not described herein.

Generally, when the circuit board 20 mounted on the top wall 11 is transferred to the inside of the electric box 100, the circuit board 20 needs to be mounted on the bottom wall 12, and other components are further disposed on the bottom wall 12, so that the area of the bottom wall 12 needs to be increased in order to be able to mount the circuit board 20, and when the area of the bottom wall 12 is increased, the size of the electric box 100 is also increased, and the cost and the occupied area of the electric box 100 are increased.

The supporting plate 60 capable of dividing the accommodating space 14 into two parts, namely an upper part and a lower part, is arranged inside the electric box 100, so that the circuit board 20 can be mounted on the supporting plate 60 to stack components of the circuit board 20 and the bottom wall 12, and the part of the space for stacking and mounting the circuit board 20 exists relative to the electric box 100 with the circuit board 20 positioned on the top wall 11, therefore, the space of the electric box 100 in the height direction is not increased, the internal space of the electric box 100 is reasonably utilized, and the circuit board 20 can be moved from the top wall 11 to the inside of the electric box 100 under the condition that the size of the electric box 100 is not increased, so that the cost and the occupied area of the electric box 100 are reduced.

Referring to fig. 8, in some embodiments, the connector 50 includes a mounting portion 51 and a fixed shaft 52.

The mounting portion 51 is disposed on the side wall 13 of the electric box 100, the two side walls 511 of the mounting portion 51 may be provided with connection holes 512 that are sized to fit the fixing shaft 52, the fixing shaft 52 is provided with the connection holes 512 in a penetrating manner, so that the mounting portion 51 is disposed thereon, the support plate 60 is connected to the fixing shaft 52, and the support plate 60 may rotate relative to the fixing shaft 52. When the support plate 60 rotates relative to the fixed shaft 52, the support plate 60 may be far away from or close to the bottom wall 12, and thus, when the top wall 11 is separated from the side wall 13 to open the accommodating space 14, the support plate 60 may be rotated to make the support plate 60 far away from or close to the bottom wall 12, and when the support plate 60 is far away from the bottom wall 12, components disposed on the bottom wall 12 may be exposed, so that a user may directly perform operations (e.g. cleaning, replacement, etc.) on the components of the bottom wall 12 without disassembling the support plate 60 and the circuit board 20.

Specifically, referring to fig. 4 and 9, a power supply 70 is provided in the electric box 100, and the support plate 60 includes a body portion 61, a protruding portion 62, and a fixing portion 63.

The body portion 61 is used for carrying the circuit board 20, the first end 621 of the protruding portion 62 is provided with a through hole 622, the fixing shaft 52 is simultaneously penetrated through the connecting hole 512 and the through hole 622, so that the supporting plate 60 is connected with the connecting piece 50, the size of the through hole 622 of the protruding portion 62 is larger than that of the fixing shaft 52, and the supporting plate 60 can rotate relative to the fixing shaft 52. The protruding portion 62 extends from the body portion 61 toward the top wall 11, so when the supporting plate 60 rotates relative to the fixed shaft 52, it is actually that the protruding portion 62 drives the body portion 61 to rotate relative to the fixed shaft 52, so that the distance between the body portion 61 and the connecting member 50 can be increased, on one hand, the rotation angle of the supporting plate 60 can be increased, and on the other hand, when the supporting plate 60 rotates to be far away from the bottom wall 12, since the distance between the body portion 61 and the connecting member 50 is large, the circuit board 20 is disposed on the body portion 61, the situation that the rotation angle of the supporting plate 60 is too large and the circuit board 20 collides with the connecting member 50 can be avoided, so as to prevent the circuit board 20 from being damaged.

One end of the fixing portion 63 is connected to the main body portion 61, and the other end of the fixing portion 63 is connected to the electric box 100.

Specifically, the fixing portion 63 also extends from the body portion 61 toward the top wall 11, an opening 631 is formed at an end of the fixing portion 63 connected to the power source 70, the power source 70 is disposed on the bottom wall 12 of the electric box 100 to provide electric power and is arranged side by side with the support plate 60, a threaded hole may be formed in a housing of the power source 70, and a screw may penetrate through the opening 631 to be screwed into the threaded hole of the power source 70 so that the fixing portion 63 is connected to the power source 70, that is, the support plate 60 is connected to the power source 70. Therefore, in the electric box 100 of the present embodiment, the number of the connectors 50 is only one, the supporting plate 60 is only required to be connected with one side wall 13 of the electric box 100, and the supporting plate 60 can be fixed at any position of the accommodating space 14, so that the accommodating space 14 is divided into two parts, and the supporting plate 60 is not required to be connected with other side walls 13 of the electric box 100, so that the area of the supporting plate 60 can be reduced, and the occupied space and the manufacturing cost of the supporting plate 60 can be reduced.

Referring to fig. 1 and 4, in some embodiments, a gap 15 is left between the support plate 60 and the sidewall 13 (the second sidewall 132), and the electric box 100 further includes a wire divider 80.

The splitter 80 is disposed on the bottom wall 12, and the splitter 80 is configured to convert a high voltage of the power source 70 into a low voltage that can be borne by the circuit board 20, so as to ensure the normal operation of the circuit board 20.

Specifically, the wire divider 80 is located below the support plate 60 and is stacked on the circuit board 20, and since the wire divider 80 needs to be connected to the circuit board 20 by a cable to transmit power to the circuit board 20, if the support plate 60 cannot rotate relative to the fixed shaft 52, the wire divider 80 is not convenient for a user to manually operate due to the small gap 15 between the support plate 60 and the second side wall 132 when being connected to the circuit board 20, so that the cable is inserted into the gap 15 to be connected to the circuit board 20. The supporting plate 60 can rotate relative to the fixed shaft 52, when the wire divider 80 needs to be operated, the supporting plate 60 can be directly rotated to enable the supporting plate 60 to be far away from the bottom wall 12, so that a user can conveniently directly take out a cable and pass through the gap 15 to be connected with the circuit board 20, and then the supporting plate 60 is rotated to enable the supporting plate 60 to be close to the bottom wall 12, so that a circuit is shielded. Therefore, attractive circuit and reasonable layout can be ensured.

Referring to fig. 4, in some embodiments, the electrical box 100 further includes a support 90.

Specifically, the support 90 is disposed on the bottom wall 12, and the support 90 includes a support surface 91. The supporting surface 91 is a surface of the supporting member 90 away from the bottom wall 12, and the wire divider 80 is disposed on the supporting surface 91. Therefore, the deconcentrator 80 can be far away from the bottom wall 12, so that the contact area between the electric box 100 and the components can be reduced, and the heat emitted by the components can not cause overheating of the box 10 when the components work.

When the electric box 100 of the embodiment of the application is used for connecting the deconcentrator 80 and the circuit board 20, the supporting plate 60 can be rotated to drive the circuit board 20 to be far away from the deconcentrator 80 and expose the deconcentrator 80, so that the deconcentrator 80 is convenient to operate and connected with the circuit board 20, and the arrangement of cables between the deconcentrator 80 and the circuit board 20 is facilitated; when the top wall 11 closes the accommodating space 14, the indicator lamp 21 can also pass through the light guide assembly 30, so that the light source emitted by the indicator lamp 21 can be accurately emitted through the through hole 111, and the state of the electric box 100 can be accurately displayed.
