[0038] This embodiment provides a controller for performing electrical control in electrical equipment or automation equipment.

[0039] Please refer to Figures 1 to 3 Specifically, the controller includes an upper shell 10, a lower shell 20, an electronic component 30 and a sealing colloid 40; the electronic component 30 is arranged in the lower shell 20, and the sealing colloid 40 is filled in the lower shell 20; the upper shell 10 and the lower shell 20 are sealed and connected; wherein, a plurality of annular waterproof parts 11 are provided on the side of the upper shell 10 facing the lower shell 20, and the annular waterproof parts 11 are inserted in the sealing colloid 40, so that the annular waterproof parts 11 form a circumferential seal to seal the upper shell 10 and the lower shell 20; an exhaust structure is provided on the upper shell 10, and the exhaust structure is used to connect the space enclosed by the upper shell 10, the sealing colloid 40 and the plurality of annular waterproof parts 11 with the outside, so that the liquid levels of the sealing colloid 40 on the inner and outer sides of the annular waterproof part 11 are equal, so that the inner and outer sides of the annular waterproof part 11 are surrounded by the sealing colloid 40, ensuring the sealing effect after the annular waterproof part 11 and the sealing colloid 40 are inserted.

[0040] The controller in this embodiment is provided with an annular waterproof portion 11 and an exhaust structure on the upper shell 10. During the assembly process of the controller, the electronic component 30 is first installed in the lower shell 20 at a preset position, and then a sealing colloid 40 is poured into the lower shell 20. The sealing colloid 40 has a certain thermal conductivity, so that the heat of the heating structure in the electronic component 30 can be quickly transferred to the lower shell 20 and dissipated, so as to achieve the heat dissipation of the electronic component 30 inside the controller; when the sealing colloid 40 has not yet solidified, the upper shell 10 is covered and fixed on the lower shell 20, and the annular waterproof portion 11 is inserted into the sealing colloid 40, and the sealing colloid 40 is squeezed to move upward. At this time, the upper shell 10 and the sealing colloid The gas in the space enclosed by the body 40 and several annular waterproof parts 11 is dissipated through the exhaust structure to ensure that the pressure of the space is the same as the external atmospheric pressure, so that the sealing colloid 40 located in the space will also move upward to cover the annular waterproof part 11 in the sealing colloid 40, and achieve circumferential sealing on the outer periphery of the upper shell 10 and the outer periphery of the upper shell 10 that cooperates with the external connecting part 31 of the electronic component 30, so that external water and other liquids cannot enter the interior of the controller, thereby improving the waterproof effect of the electronic component 30 inside the controller; and reducing parts such as sealing rings and process steps such as gluing or assembling sealing rings, simplifying the assembly process and reducing production costs.

[0041] In order to achieve the limited fixation between the upper shell 10 and the lower shell 20, in some embodiments, the upper shell 10 is provided with a plurality of snap-fit ​​structures 15 on one side facing the lower shell 20 and close to its own periphery, and the snap-fit ​​structures 15 are snap-fitted and connected to the lower shell 20; thus, the connection between the upper shell 10 and the lower shell 20 can be achieved.

[0042] In some embodiments, the electronic component 30 includes a plurality of external connectors 31 and a plurality of electrical components 32. Both the electrical components 32 and the external connectors 31 are installed in the lower shell 20, and the electrical connection between the plurality of electrical components 32 and the plurality of external connectors 31 is realized according to design requirements. The external connectors 31 are used for the external electrical connection of the controller, thereby realizing the circuit connection and external circuit connection of the controller.

[0043] Please refer to Figures 1 to 4 In this embodiment, the number and position of the annular waterproof part 11 are adaptively changed according to the actual needs of the controller, that is, the position and number of the openings on the upper shell 10 and the ones to be sealed are adaptively changed, and no specific limitation is made here.

[0044] Exemplarily, in this embodiment, an annular waterproof portion 11 is circumferentially provided on the side of the upper shell 10 facing the lower shell 20 and close to its own periphery, as well as on the periphery of the upper shell 10 and the outer periphery of the external connecting part 31 of the electronic component 30. That is, after the upper shell 10 and the lower shell 20 are installed, all locations on the upper shell 10 that are prone to water ingress are provided with annular waterproof portions 11, so that the upper shell 10 and the lower shell 20 are completely sealed, so that water and other liquids cannot enter the interior of the controller, thereby increasing the waterproof and sealing effects.

[0045] Furthermore, the electronic component 30 includes a plurality of external connectors 31, and the upper housing 10 is provided with a plurality of openings 101, which are arranged one by one corresponding to the external connectors 31, and the openings 101 are used for the extension of the external connectors 31, and an annular waterproof portion 11 is arranged circumferentially at the openings 101. That is, each opening 101 from which the external connectors 31 extend also needs to be waterproof and sealed, and therefore, an annular waterproof portion 11 is arranged at each opening 101, which, together with the outermost annular waterproof portion 11 of the upper housing 10 itself and the sealing colloid 40, forms a waterproof sealing structure for the interior of the controller, so that liquids such as water cannot enter the interior of the controller, thereby increasing the waterproof and sealing effects.

[0046] Optionally, the external connecting member 31 is provided with an abutment portion 311, which is arranged in cooperation with the annular waterproof portion 11 to support the annular waterproof portion 11 at the opening 101, thereby preventing the annular waterproof portion 11 from sinking and being inserted too deeply into the sealing colloid 40, causing the sealing colloid 40 to leak out, thereby improving the reliability of the controller.

[0047] Further optionally, the abutting portion 311 is a circumferential annular structure, that is, the abutting portion 311 can support various positions of the annular waterproof portion 11 .

[0048] In some embodiments, at least part of the insertion end of the annular waterproof portion 11 is provided with a guiding bevel portion, so that the annular waterproof portion 11 is inserted into the sealing colloid 40. During assembly, when the annular waterproof portion 11 is inserted into the sealing colloid 40, the guiding bevel portion first contacts the sealing colloid 40, and the sealing colloid 40 can be squeezed upward with the bevel surface to seal, so as to facilitate the assembly of the two and guide the sealing colloid 40; and prevent the sealing colloid 40 from flowing too fast and overflowing due to the large area of ​​the insertion end of the annular waterproof portion 11.

[0049] Please refer to Figures 5 to 7 In some embodiments, at least a portion of the insertion end of the annular waterproof portion 11 is provided with a plurality of grooves 111, and at least a portion of the grooves 111 is filled with a sealing colloid 40, that is, the end of the annular waterproof portion 11 inserted into the sealing colloid 40 is in a U-shape, a V-shape, a W-shape, etc., thereby increasing the contact area between the annular waterproof portion 11 and the sealing colloid 40, and further allowing the sealing colloid 40 to form a multi-layer seal from the outside of the controller to the inside of the controller, thereby improving the sealing performance of the controller.

[0050] In some other embodiments, the formation of the groove 111 can also be achieved by setting up a plurality of annular waterproof portions 11, that is, the plurality of annular waterproof portions 11 are spaced apart from the inner side of the controller toward the outside, and a groove 111 is formed between two adjacent annular waterproof portions 11, which can also enable the sealing colloid 40 to form a multi-layer seal from the outer side of the controller to the inner side of the controller, thereby improving the sealing performance of the controller.

[0051] In some embodiments, a plurality of reinforcing ribs 14 are provided on both sides of the annular waterproof portion 11 to improve the structural strength of the annular waterproof portion 11 and the structural strength of the upper shell 10, thereby avoiding the problem of sealing failure caused by damage to the annular waterproof portion 11 or the upper shell 10, thereby improving the reliability of the controller.

[0052] In some embodiments, the lower housing 20 is further provided with heat dissipation fins so that the heat of the electronic component 30 can be dissipated more quickly after being conducted to the lower housing 20 .

[0053] In this embodiment, the exhaust structure is selected to be a structure that can not only achieve air permeability between the inside and outside of the upper shell 10, but also meet the required waterproof sealing level, so that it can achieve exhaust while ensuring the sealing effect of the controller.

[0054] In some optional embodiments, the exhaust structure is a breathable membrane, and an exhaust hole 12 is opened on the upper shell 10, and a breathable membrane is provided on the exhaust hole 12 to achieve ventilation inside and outside the controller to balance the air pressure inside and outside the controller, and also to ensure the waterproof sealing effect of the controller.

[0055] In some optional embodiments, the exhaust structure is a breathable valve, and the breathable valve is sealed on the upper shell 10, which can achieve the balance of the air pressure inside and outside the controller and ensure the waterproof sealing effect of the controller.

[0056] In some embodiments, a plurality of ribs are disposed on a side of the upper shell 10 facing the lower shell 20 , and the plurality of ribs are used to improve the structural strength of the upper shell 10 .

[0057] Since the arrangement of multiple ribs may cause the inner side of the annular waterproof part 11 at some openings 101 to be unable to communicate with the exhaust structure, during the installation of the upper shell 10 and the lower shell 20, the air pressure at this location may be higher than the external air pressure, causing the liquid level of the sealing colloid 40 on the inner and outer sides of the annular waterproof part 11 at this location to be different, thereby affecting the sealing effect. Figure 4 In some embodiments, an exhaust passage 13 is provided on one side of the upper shell 10 facing the lower shell 20, and the inner side of the annular waterproof portion 11 is arranged in the exhaust passage 13, so that each position in the space enclosed by the upper shell 10, the sealing colloid 40 and several annular waterproof portions 11 is arranged in the exhaust passage 13, so as to avoid the occurrence of a position where local closure and pressure relief cannot occur, resulting in the problem of different heights of the sealing colloid 40 on the inner and outer sides of the annular waterproof portion 11 at this position, thereby avoiding the problem of poor sealing effect here affecting the sealing of the controller, and improving the reliability of the sealing and waterproofing of the controller.

[0058] Specifically, at least some of the ribs are provided with exhaust grooves 131, and the exhaust grooves 131 connect various positions inside the upper shell 10 to form an exhaust channel 13, so that the inner side of each annular waterproof part 11 is connected to the exhaust structure, thereby balancing the air pressure inside and outside the annular waterproof part 11.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
