[0039] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a controller is provided, including a main body 10 , a control board 40 , a conductive part 20 and a first sealing member 30 .
[0040] The main body 10 is provided with an installation cavity, and a through hole 124 is provided on the outer peripheral side wall of the main body 10, and the through hole 124 is connected to the installation cavity. The control board 40 is arranged in the installation cavity. The conductive part 20 is penetrated at the through hole 124 and is electrically connected to the control board 40. The first sealing member 30 is arranged between the through hole 124 and the conductive part 20.
[0041] Specifically, the controller is used to connect with a motor, a power supply or other equipment, and change the current through the control board 40 to control other equipment. In this embodiment, the conductive part 20 can be a cable of a motor, a power supply or other equipment, or a component for wiring that passes through the controller inside the controller. Compared with the prior art, a first seal 30 is provided between the conductive part 20 and the through hole 124 of this embodiment. The first seal 30 seals the conductive part 20 and the main body 10, thereby preventing external water stains from entering the installation cavity through the through hole 124, and preventing the control board 40 and the cable 21 from short-circuiting.
[0042] In some embodiments, the conductive part 20 is a wire connecting the external device and the controller. By connecting the wire between the external device and the controller, and the wire is directly connected to the control board 40, it is avoided to set terminals on the outer peripheral side wall of the controller, which causes the controller to short-circuit due to the action of water when the controller is immersed in water.
[0043] Further, the first sealing member 30 includes a threaded rubber ring.
[0044] Specifically, the threaded rubber ring has multiple sealing pads 34, which have multiple waterproof effects, that is, when the main body 10 contacts external water stains, the outermost sealing pad 34 first plays a waterproof role. If the water stains pass through the outermost sealing pad 34, the inner sealing pad 34 can block the water stains again, thereby further improving the protection performance of the controller.
[0045] Further, along the extension direction of the through hole 124, the threaded rubber ring includes a first thread segment 31, a connecting segment 32 and a second thread segment 33 in sequence, the first thread segment 31 is arranged outside the main body 10 and abuts against the outer peripheral side wall of the main body 10, the connecting segment 32 is arranged in the through hole 124 with interference fit, and the second thread segment 33 is arranged in the installation cavity and abuts against the inner side wall of the main body 10. Among them, the minimum radius of the first thread segment 31 and the second thread segment 33 are both greater than the radius of the through hole 124.
[0046] Specifically, the first thread segment 31 and the second thread segment 33 each include a plurality of sealing pads 34, and the first thread segment 31 and the second thread segment 33 can block water stains in turn, completely isolating the water stains outside the installation cavity. At the same time, in this embodiment, a connecting segment 32 is provided between the first thread segment 31 and the second thread segment 33, and the connecting segment 32 is interference-fitted in the through hole 124, so as to prevent water stains from entering the installation cavity through the gap between the connecting segment 32 and the through hole 124.
[0047] In addition, the through holes 124 include a plurality of through holes 124, which are arranged at intervals along the outer circumference of the main body 10. The conductive parts 20 include a plurality of conductive parts 20, which are arranged in a one-to-one correspondence at the plurality of through holes 124, and the plurality of conductive parts 20 are electrically connected to the control board 40. The threaded rubber rings include a plurality of threaded rubber rings, which are arranged in a one-to-one correspondence at the plurality of through holes 124.
[0048] Specifically, in this embodiment, a plurality of through holes 124 are provided on the outer periphery of the main body 10, so that the plurality of conductive parts 20 can be connected to the control board 40 at different positions. At the same time, the plurality of conductive parts 20 can be connected to different devices. For example, some conductive parts 20 are respectively connected to the control board 40 and the external motor, while other conductive parts 20 are respectively connected to the control board 40 and the power supply.
[0049] To avoid the situation that the cable 21 is welded with the control board 40 and the cable 21 is separated from the control board 40 due to long-term use. The conductive part 20 includes a cable 21 and a connector 22. The cable 21 is inserted into the through hole 124. The connector 22 is connected to the end of the cable 21 in the installation cavity and is electrically connected to the control board 40. Specifically, the connector 22 is provided at the end of the cable 21, and the control board 40 is connected through the connector 22, which can improve the connection strength between the cable 21 and the control board 40, and prevent the cable 21 from being separated from the control board 40 after long-term use.
[0050] In other specific embodiments, connectors 22 are provided at both ends of the cable 21, and the connectors 22 are respectively connected to the control board 40 and the controller external device to enhance the connection stability between the cable 21 and the control board 40 or the cable 21 and the external device. In addition, the connector 22 includes a cold-pressed terminal. In some embodiments, a wiring copper column 41 is provided on the control board 40, and the cold-pressed terminal is locked on the wiring copper column 41 by bolts. The design of this embodiment can prevent the cable 21 from being too long, thereby improving the space utilization rate in the controller.
[0051] To further improve the sealing performance between the cable 21 and the first sealing member 30. In this embodiment, the first sealing member 30 is disposed on the cable 21, and a sealing adhesive layer (not shown in the figure) is disposed between the first sealing member 30 and the cable 21. In this embodiment, the sealing adhesive layer includes a sealant layer.
[0052] Further, the main body 10 includes a bottom plate 11, an annular shell 12 and a top cover 13. The control board 40 is fixedly arranged on the bottom plate 11. The annular shell 12 is covered on the bottom plate 11. The top cover 13 is covered on the annular shell 12. The bottom plate 11, the annular shell 12 and the top cover 13 are surrounded to form an installation cavity.
[0053] In this embodiment, the control board 40 is fixed on the bottom plate 11, and the design of the annular housing 12 and the top cover 13 facilitates maintenance of the controller. In a specific embodiment, if the seal between the bottom plate 11 and the annular housing 12 fails or the seal between the annular housing 12 and the top cover 13 fails, the bottom plate 11, the annular housing 12 or the top cover 13 can be repaired separately.
[0054] Furthermore, a second sealing member 50 is provided between the bottom plate 11 and the annular housing 12. Specifically, in some embodiments, a first annular groove is provided on one side of the bottom plate 11 close to the annular housing 12 or on one side of the annular housing 12 close to the bottom plate 11, and the second sealing member 50 is filled in the first annular groove, and the annular housing 12 is fixed to the bottom plate 11 by bolts.
[0055] Optionally, a third seal 60 is provided between the annular housing 12 and the top cover 13. Similarly, in some embodiments, a second annular groove is provided on one side of the annular housing 12 close to the top cover 13 or on one side of the top cover 13 close to the annular housing 12, and the third seal 60 is filled in the second annular groove, and the top cover 13 is fixed to the annular groove by bolts. In this embodiment, the second seal 50 and the third seal 60 are both rubber gaskets. Under the action of the first seal 30, the second seal 50 and the third seal 60, the controller can achieve IP67 performance waterproofing of the whole machine.
[0056] Furthermore, a partition 122 is provided on the annular shell 12, and the partition 122 divides the installation cavity into a first chamber and a second chamber. The bottom plate 11 is arranged in the first chamber, and the through hole 124 is arranged on the annular shell 12 and connected with the second chamber. A first channel 123 is provided between the second chamber and the first chamber, and the first channel 123 is at least used to inject sealant into the first chamber to form a glue injection layer in the first chamber.
[0057] After the base plate 11 and the annular housing 12 are assembled, in order to prevent water stains from entering the installation cavity after the threaded rubber ring is damaged, causing the control board 40 to short-circuit, the second chamber needs to be sealed with glue to prevent water stains from contacting the control board 40. Specifically, after the base plate 11 and the annular housing 12 are assembled, the sealant is poured into the second chamber, and the sealant moves from the first channel 123 to the second chamber, and forms a glue layer after cooling. In some specific embodiments, the conductive part 20 is arranged in the second chamber, and the wiring copper column 41 of the control board 40 passes through the second chamber from the first chamber to facilitate connection with the conductive part 20.
[0058] In addition, a transparent window 121 is provided on the side wall of the second chamber. Specifically, the transparent window 121 includes a transparent medium and an observation port. The annular housing 12 is provided with an observation port, which is connected to the first chamber, and a transparent plastic plate is provided to seal the outer periphery of the observation port. When injecting the sealant, the injection condition in the first chamber can be observed through the transparent plastic plate.
[0059] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0060] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
[0061] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
