[0041] At present, the controller is a device that connects household energy storage and energy-consuming devices, and realizes the scheduling optimization and unification of household energy by controlling household energy storage and energy-consuming devices. As an important energy scheduling controller, the controller has higher requirements for environmental adaptability. However, since the controller is usually installed in the distribution box or on the wall of the household building, it is easily affected by other heating devices or solar radiation, which makes the ambient temperature around the controller rise. At the same time, the heat generated by the device itself increases the internal temperature of the controller, which may cause the controller to work unstably, shut down or even fail, resulting in significant changes in the devices controlled by the controller and affecting the energy use safety.

[0042] Based on this, the present utility model proposes a control device for household energy devices, aiming to solve the problem that the increase in the internal temperature of the controller may cause the controller to work unstably. Among them, Figures 1 to 3 is a schematic structural diagram of the control device provided by the present utility model.

[0043] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the control device 100 includes a housing 1 and a circuit board structure 2. Two sub-cavities are formed in the housing 1 along a first direction. The circuit board structure 2 includes two circuit board components that are electrically connected to each other. The two circuit board components are respectively arranged in the two sub-cavities.

[0044] In the technical solution of the present utility model, by setting the housing 1 to form two sub-cavities, and by setting two circuit board components that are electrically connected to each other, on the one hand, the circuit board structure 2 can be used to control the household energy devices, and on the other hand, the household energy devices can be controlled separately, so that the heat generating modules of the circuit board structure 2 are separated, such as the communication module and the logic module, etc., which is not only convenient for heat dissipation, but also can avoid local overheating. At the same time, the two circuit board components are respectively arranged in the two sub-cavities, so that the two circuit board components have relatively independent areas for heat dissipation, which is beneficial to separately dissipate heat from each circuit board component, improve the heat dissipation effect of the control device 100, and reduce the risk that the circuit board components in the housing 1 work unstably due to too high temperature.

[0045] It should be noted that there are various first directions, which can be left-right direction, front-back direction, etc. The present utility model does not limit this. Exemplarily, the first direction is the length direction of the housing 1.

[0046] Further, in order to form two sub-cavities in the housing 1, in this embodiment, please refer to Figure 2 and Figure 3, an installation cavity 11 is formed in the housing 1, and a separator 3 is provided in the installation cavity 11 to divide the installation cavity 11 into two sub-cavities. In this way, by providing the separator in the installation cavity 11, the installation cavity 11 is divided into two sub-cavities.

[0047] Furthermore, there are various connection methods between the separator 3 and the housing 1. For example, the separator 3 can be fixed in the housing 1 by screws or by bonding, etc. The present invention does not limit this. Specifically, in this embodiment, the separator 3 is detachably installed in the housing 1. In this way, the detachable connection method is adopted to adjust the sizes of the two sub-cavities so that the two sub-cavities can adapt to the two circuit board assemblies. Furthermore, there are various detachable connection methods. For example, it can be a screw connection structure or a snap connection structure, etc. The present invention does not limit this.

[0048] In an embodiment of the present invention, at least one end of the two ends of the separator 3 in the second direction forms a gap with the side wall of the installation cavity 11 to communicate the two sub-cavities. In this way, the separator 3 and the housing 1 are arranged with a gap so that the two sub-cavities can communicate, facilitating the flow of gas between the two sub-cavities to balance the temperature difference between the two sub-cavities. Of course, in other embodiments, the two sub-cavities can also be isolated from each other. The present invention does not limit this. Furthermore, one end of the separator 3 can be arranged with a gap with the side wall of the installation cavity 11, or both ends can be arranged with a gap with the side wall of the installation cavity 11. The present invention does not limit this. Specifically, in this embodiment, both ends of the separator 3 are arranged with a gap with the side wall of the installation cavity 11. In this way, the gas can flow along the circumference of the circuit board, which is beneficial to the formation of a circular flow of gas in the installation cavity 11, thereby facilitating the flow of gas between the two sub-cavities.

[0049] It should be noted that there are various second directions, which can be the up-down direction or the front-back direction, etc. The present invention does not limit this. Exemplarily, please refer to Figure 3 , the second direction is the width direction of the housing 1.

[0050] The volumes of the two sub-cavities can be the same or different. The present invention does not limit this. Specifically, in this embodiment, please refer to Figure 3, the two sub - cavities include a first sub - cavity 111 and a second sub - cavity 112. The volume of the first sub - cavity 111 is larger than that of the second sub - cavity 112, so that the two sub - cavities can accommodate two circuit board assemblies of different sizes, which is conducive to improving the space utilization rate inside the housing 1, thereby helping to reduce the size of the housing 1.

[0051] In an embodiment of the present invention, please refer to Figure 3 , the two circuit board assemblies include a first circuit board assembly 21 disposed in the first sub - cavity 111. A gap is formed between the first circuit board assembly 21 and the side wall of the first sub - cavity 111. In this way, the first circuit board assembly 21 and the side part of the sub - cavity are arranged with a gap, so that gas can flow along the circumference of the first circuit board, in order to take away the heat in the first sub - cavity 111 in time and improve the heat dissipation effect of the control device 100.

[0052] In an embodiment of the present invention, please refer to Figures 1 to 3 , the housing 1 is provided with heat dissipation holes 12, and the heat dissipation holes 12 communicate with at least one of the sub - cavities. In this way, by providing the heat dissipation holes 12, the sub - cavity can communicate with the outside of the housing 1, so that gas can enter and exit the sub - cavity, and the heat in the sub - cavity can be dissipated into the air outside the housing 1.

[0053] Furthermore, in an embodiment of the present invention, the two sub - cavities include a first sub - cavity 111 and a second sub - cavity 112. A plurality of heat dissipation holes 12 are provided. The plurality of heat dissipation holes 12 include a first heat dissipation hole 121. The first heat dissipation hole 121 is disposed at one end of the housing 1 along the second direction and corresponds to communicating with the first sub - cavity 111. In this way, by providing the first heat dissipation hole 121, the first sub - cavity 111 is communicated with the outside of the housing 1, so that gas can enter and exit the first sub - cavity 111, and the heat in the first sub - cavity 111 can be dissipated into the air outside the housing 1. At the same time, the plurality of first heat dissipation holes 121 are disposed at one end of the housing 1 to prevent dust and other impurities from entering the first sub - cavity 111 from the other end of the housing 1.

[0054] It should be noted that when the housing 1 is arranged vertically, if the first heat dissipation hole 121 is arranged at the upper end of the housing 1, dust and other impurities are likely to enter the first sub - cavity 111 through the first heat dissipation hole 121, resulting in dust accumulation at the upper end of the circuit board assembly. Therefore, the first heat dissipation hole 121 is arranged at the lower end of the housing 1 to prevent impurities from entering the first sub - cavity 111 through the first heat dissipation hole 121, thereby avoiding dust accumulation at the upper end of the circuit board.

[0055] In another embodiment of the present utility model, the plurality of heat dissipation holes 12 include a plurality of second heat dissipation holes 122. The plurality of second heat dissipation holes 122 are respectively arranged at both ends of the housing 1 along the second direction and are correspondingly communicated with the second sub-chamber 112. Thus, by providing the second heat dissipation holes 122, the second sub-chamber 112 is communicated with the outside of the housing 1, enabling gas to enter and exit the second sub-chamber 112, so that the heat in the second sub-chamber 112 can be dissipated into the air outside the housing 1. At the same time, the plurality of second heat dissipation holes 122 are respectively arranged at both ends of the housing 1, enabling the air flow to flow unidirectionally along the width direction of the housing 1, facilitating the rapid entry and exit of gas from the second sub-chamber 112, thereby contributing to improving the heat dissipation effect of the control device 100.

[0056] It should be noted that for the above two related technical features: "the plurality of heat dissipation holes 12 include the first heat dissipation hole 121, the first heat dissipation hole 121 is arranged at one end of the housing 1 along the second direction and is correspondingly communicated with the first sub-chamber 111", and "the plurality of heat dissipation holes 12 include a plurality of second heat dissipation holes 122, the plurality of second heat dissipation holes 122 are respectively arranged at both ends of the housing 1 along the second direction and are correspondingly communicated with the second sub-chamber 112", either one can be set or both can be set simultaneously. The present utility model does not make any limitation in this regard.

[0057] In an embodiment of the present utility model, please refer to Figure 2 and Figure 3 , the housing 1 includes a housing main body 13 and two cover bodies 14 arranged at both ends of the housing main body 13. The two sub-chambers are defined between the housing main body 13 and the two cover bodies 14. The first heat dissipation hole 121 and the plurality of second heat dissipation holes 122 at the same end of the housing 1 along the second direction are arranged on one of the cover bodies 14, and the remaining plurality of second heat dissipation holes 122 are arranged on the other cover body 14. Thus, by providing the housing main body 13 and the cover bodies 14, it is not only convenient to jointly enclose the installation cavity 11, but also convenient to provide the first heat dissipation hole 121 and the second heat dissipation holes 122, which is beneficial to reducing the difficulty of opening holes. Moreover, by replacing the cover body 14, the sizes of the first heat dissipation hole 121 and the second heat dissipation holes 122 can be adjusted to be adapted to the two sub-chambers.

[0058] It can be understood that there are various connection methods between the shell body 13 and the cover body 14. The shell body 13 and the cover body 14 can be connected by screws or adhesives, etc. The present utility model does not limit this. Specifically, in this embodiment, the cover body 14 is detachably installed on the shell body 13. In this way, a detachable connection method is adopted to facilitate the disassembly of the cover body 14, which is convenient for subsequent maintenance or replacement of the circuit board assembly. Further, there are various detachable connection methods. For example, it can be a screw connection structure or a snap connection structure, etc. The present utility model does not limit this.

[0059] Further, there are various materials for the shell body 13. Specifically, in this embodiment, the material of the shell body 13 is a metal material. Since metal has good heat conduction performance, the use of a metal material helps to reduce the heat conduction thermal resistance of the shell body 13, enabling the shell body 13 to radiate more heat to the outside, thereby contributing to improving the heat dissipation effect of the control device 100. Particularly, the shell body 13 can be subjected to anodic oxidation treatment to further enhance the heat dissipation effect of the shell body 13. Of course, in other embodiments, the shell body 13 can be made of a ceramic material, etc. The present utility model does not limit this.

[0060] It can be understood that there are various forming methods for the shell body 13. For example, the shell body 13 can be integrally formed or assembled and formed. The present utility model does not limit this. Specifically, in this embodiment, the shell body 13 is integrally extrusion formed, which is not only convenient for forming but also can improve the appearance effect of the shell 1.

[0061] In an embodiment of the present utility model, the material of the cover body 14 is a plastic material. Since the density of plastic is relatively small, the use of a plastic material is to reduce the weight of the cover body 14, which is beneficial to reducing the weight of the shell 1. Of course, in other embodiments, the material of the cover body 14 can also be a metal material, etc. The present utility model does not limit this.

[0062] It should be noted that for the above two related technical features: "the material of the shell body 13 is a metal material" and "the material of the cover body 14 is a plastic material", either one can be set or both can be set simultaneously. The present utility model does not limit this.

[0063] Since the second heat dissipation holes 122 are provided at both ends of the second sub - cavity 112, the width dimension of the second sub - cavity 112 can be reduced. However, such a setting is not conducive to laying out the circuit board in the width direction. Therefore, in this embodiment, please refer to Figure 2 and Figure 3, the two sub - cavities include a first sub - cavity 111 and a second sub - cavity 112 arranged along a first direction, the two circuit board assemblies include a first circuit board assembly 21 and a second circuit board assembly 22, and the second circuit board assembly 22 is longitudinally disposed in the second sub - cavity 112 along a second direction. In this way, the second circuit board assembly 22 is longitudinally arranged so that the second circuit board assembly 22 can be adapted to the second sub - cavity 112, which is conducive to improving the space utilization rate of the second sub - cavity 112.

[0064] Please refer to Figure 2 , the circuit board assembly includes a main board 211 and a connector 212 arranged on the main board 211. The heat dissipation holes 12 are arranged corresponding to the connector 212 so that the wire harness can enter the installation cavity 11 through the heat dissipation holes 12 to be connected to the connector 212, so that the heat dissipation holes 12 can be used for heat dissipation and wire passing, so as to avoid additionally arranging wire passing holes.

[0065] In order to improve the heat dissipation effect of the housing 1, in this embodiment, please refer to Figure 1 and Figure 2 , the housing 1 has a heat dissipation side end in a third direction, and a plurality of heat dissipation fins 4 are arranged on the heat dissipation side end. The plurality of heat dissipation fins 4 are arranged at intervals along the first direction. In this way, by arranging the heat dissipation fins 4, the heat dissipation area of the housing 1 can be increased, so that the housing 1 can radiate more heat to the outside, which helps to improve the heat dissipation effect of the control device 100.

[0066] It should be noted that there are various third directions, which can be the front - to - back direction or the left - to - right direction, etc. The present invention does not limit this. Exemplarily, please refer to Figure 2 , the third direction is the thickness direction of the housing 1.

[0067] Furthermore, a plurality of the heat dissipation fins 4 are correspondingly arranged in heat dissipation groups. In the third direction, the heat dissipation group is arranged corresponding to at least a part of one of the sub - cavities, so that the heat dissipation fins 4 can cover at least a part of the sub - cavity, so that the heat in the sub - cavity can be timely dissipated to the outside of the housing 1. It can be understood that the plurality of heat dissipation fins 4 can cover two sub - cavities, or can cover one sub - cavity, or can cover a part of one sub - cavity, etc. The present invention does not limit this.

[0068] In an embodiment of the present utility model, a part of the plurality of heat dissipation fins 4 is correspondingly arranged at the heat dissipation side end and is set as a heat dissipation side wall part. The housing 1 is made of a metal material at least in the material of the heat dissipation side wall part. In this way, the part of the housing 1 corresponding to the heat dissipation fins 4 is made of a metal material to reduce the thermal resistance of the housing 1, so that the heat in the sub-chamber can be timely transferred to the heat dissipation fins 4 and dissipated to the surrounding environment through the heat dissipation fins 4, thereby helping to improve the heat dissipation effect of the housing 1.

[0069] In an embodiment of the present utility model, please refer to Figure 2 and Figure 3 , the two sub-chambers include a first sub-chamber 111 and a second sub-chamber 112 arranged along a first direction. The two circuit board assemblies include a first circuit board assembly 21 and a second circuit board assembly 22. The first circuit board assembly 21 is horizontally arranged in the first sub-chamber 111 along the first direction. In this way, the first circuit board assembly 21 is horizontally arranged so that the first circuit board assembly 21 can be adapted to the first sub-chamber 111, thereby helping to improve the space utilization rate of the first sub-chamber 111.

[0070] In an embodiment of the present utility model, a temperature sensor is provided on at least one of the circuit board assemblies, and the temperature sensor is electrically connected to the corresponding circuit board assembly. In this way, by setting the temperature sensor, the temperature of the circuit board assembly can be detected, thereby helping to control the temperature of the circuit board assembly and avoiding the temperature of the circuit board assembly being too high or too low.
