Description

Technical Field

[0001] The utility model relates to the technical field of underwater equipment, in particular to a power control box and an underwater robot. Background Art

[0002] Underwater equipment refers to equipment that operates underwater. Underwater robots are a common type of underwater equipment. Underwater robots can replace humans to enter underwater and complete various tasks, and have played a great role in underwater environmental testing, underwater construction and other fields.

[0003] In order to ensure that the underwater robot can work continuously, the underwater robot is usually connected to a power control box through a cable so that the power control box can stably supply power to the underwater robot. In order to facilitate the staff to control the circuit and improve the safety and stability of the power control box, the power control box is fixed on the shore so that the underwater robot can perform the predetermined work within the length of the cable.

[0004] Since the power control box is often used on the shore near the water, in order to protect the electronic components in the power control box, the structure of the power control box usually needs to be waterproof. Since the power control box often needs to be exposed to the outdoor environment, when the temperature is high and the sun continues to expose the power control box, the temperature inside the power control box rises, which may affect the normal operation of the internal components. Under the change of air pressure, the keycaps made of soft materials (such as rubber, plastic) may be deformed, thereby causing abnormal key presses. Or, due to the change of air pressure inside the power control box, the internal structure of the power control box is sunken or bulged toward the outside, thereby destroying the waterproof structure of the power control box, allowing liquid to enter the power control box and cause short circuits in the electronic components, resulting in poor safety and stability of the power control box.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] See also Figure 1-Figure 3 The utility model provides a power control box, including a box body 1, a control board 2, a power adapter 3, a first interface 123, and a second interface 124. The box body 1 includes an upper cover 11 and a lower shell 12, and the upper cover 11 and the lower shell 12 are sealed to form a control cavity 13 inside. The box body 1 is provided with a first heat dissipation window 121; the first heat dissipation window 121 is covered with a waterproof and breathable component 8 to close the control cavity 13; the control board 2 is arranged inside the control cavity 13; the power adapter 3 is arranged inside the control cavity 13 and is electrically connected to the control board 2; the first interface 123 is arranged on the box body 1, and is electrically connected to the power adapter 3 to input electric energy; the second interface 124 is arranged on the box body 1, and is electrically connected to the control board 2 to output electric energy.

[0041] The upper cover 11 and the lower shell 12 are buckled and connected, the first interface 123 and the second interface 124 are respectively arranged at two ends of the lower shell 12 in the length direction, and the first heat dissipation window 121 is opened on the side wall of the lower shell 12 .

[0042] It should be noted that the lower shell 12 can be optionally connected to a power cord (not shown in the figure) and a cable (not shown in the figure), one end of the power cord is connected to the first interface 123, and the other end is provided with a plug for connecting to the circuit and transmitting current to the power adapter 3; the cable is connected to the second interface 124, and is used to transmit current and signals to the underwater equipment powered by the power control box, and the lower shell 12 is provided with a protective shell 125 at the position corresponding to the first interface 123 and the second interface 124, which is used to protect the connection between the power cord and the lower shell 12, and the connection between the cable and the lower shell 12.

[0043] In this way, by inserting the power cord and the cable into the first interface 123 and the second interface 124 respectively, the current can be transmitted to the powered underwater equipment through the power cord, the power adapter 3, and the cable, thereby realizing continuous and stable power supply to the equipment working underwater; the first heat dissipation window 121 can balance the pressure between the control cavity 13 and the outside world, and avoid the box body 1 and the keycap 111 made of soft material from bulging or sinking due to the pressure difference between the control cavity 13 and the outside world, thereby affecting the normal operation of the keycap 111; the waterproof and breathable component 8 can prevent external liquid from entering the control cavity 13, thereby improving the safety and stability of the power control box.

[0044] It can be understood that regarding the opening of the first heat dissipation window 121, multiple heat dissipation windows can be opened on one of the side walls of the lower shell 12, or a first heat dissipation window 121 can be opened on each of the multiple side walls. In the present embodiment, the first heat dissipation window 121 is opened on one of the side walls of the lower shell 12 along its length direction, and the length direction of the first heat dissipation window 121 is parallel to the length direction of the lower shell 12.

[0045] See also Figure 1 In some embodiments, the upper cover 11 extends downward along both sides in the length direction thereof, so that the upper cover 11 forms an eaves structure, and the side walls of the upper cover 11 protrude from the side walls of the lower shell 12.

[0046] In this way, when it rains or liquid is splashed onto the upper cover 11, the liquid can flow to the ground along the slope of the top surface of the upper cover 11, and is not easy to accumulate on the top surface of the upper cover 11 or enter the lower shell 12 through the first heat dissipation window 121, thereby improving the waterproof performance and safety of the box body 1.

[0047] See also Figure 4 In some embodiments, the waterproof breathable component 8 includes a waterproof breathable membrane 81 and a mounting frame 82 , and the waterproof breathable membrane 81 is covered and mounted on the first heat dissipation window 121 through the mounting frame 82 .

[0048] In this embodiment, the area of ​​the waterproof breathable membrane is larger than the area of ​​the first heat dissipation window 121, and the waterproof breathable membrane is arranged inside the lower shell 12. The waterproof breathable membrane includes a first layer (not shown in the figure) and a second layer (not shown in the figure), the first layer is arranged toward the inside of the control cavity 13, and the second layer is arranged on the side of the first layer away from the inside of the control cavity 13, the first layer is made of polyester material, and the second layer is made of PTFE (Polytetrafluoroethylene, polytetrafluoroethylene) material, and the first layer is fixedly connected to the second layer; the thickness of the waterproof breathable membrane is 0.15mm.

[0049] The mounting frame 82 is provided with a hole matching the area of ​​the first heat dissipation window 121 , and the mounting frame 82 is connected to the lower shell 12 by bolts, so that the waterproof breathable membrane is arranged between the lower shell 12 and the mounting frame 82 , thereby limiting the waterproof breathable membrane.

[0050] In this way, by setting up a waterproof and breathable membrane, the outside air can be exchanged with the air inside the control cavity 13, and while balancing the air pressure, it can prevent external liquid from entering the control cavity 13 through the first heat dissipation window 121. The waterproof and breathable membrane can also prevent external dust from entering the control cavity 13, further improving the stability and safety of the power control box.

[0051] It is understandable that the specific structure, thickness and area of ​​the waterproof breathable membrane 81 can be adjusted according to actual needs, and will not be elaborated here.

[0052] See also Figure 4 In some embodiments, the waterproof breathable component 8 may further include a waterproof breathable membrane 81 and a glue layer (not shown in the figure), the glue layer is arranged around the waterproof breathable membrane 81, and the waterproof breathable membrane 81 is covered by the glue layer and bonded to the first heat dissipation window 121. The waterproof breathable membrane 81 is bonded to the inner wall of the lower shell 12 through the glue layer. Specifically, a 3M glue is arranged on one side edge of the waterproof breathable membrane 81 facing the inner wall of the lower shell 12, and the thickness of the 3M glue is 0.15 mm.

[0053] See also Figure 3 In some embodiments, the first heat dissipation window 121 includes a plurality of reinforcing ribs 14 to separate the first heat dissipation window 121 into a plurality of heat dissipation holes, and the waterproof breathable component 8 includes a plurality of waterproof breathable membranes 81, each waterproof breathable membrane 81 correspondingly covers a heat dissipation hole to close the first heat dissipation window 121.

[0054] In this way, the reinforcing ribs 14 can strengthen the structural strength of the lower shell 12 at the location where the first heat dissipation window 121 is opened, while ensuring the exchange of outside air with the air in the control cavity 13, maintaining good ventilation and heat dissipation performance inside the box body 1, and achieving pressure balance between the inside of the box body 1 and the outside world, thereby avoiding deformation of the keycap 111 due to pressure difference.

[0055] See also Figure 3 In some embodiments, the control panel 2 is disposed in the control cavity 13 on a side close to the upper cover 11 , and a control switch 21 is disposed on the control panel 2 , and a key cap 111 is disposed on the upper cover 11 corresponding to the control switch 21 .

[0056] In this embodiment, the control panel 2 is detachably connected to the upper cover 11 by bolts, and the power adapter 3 is arranged at the bottom of the lower shell 12. Along the height direction of the lower shell 12, a gap is left between the top surface of the power adapter 3 and the bottom surface of the control panel 2. The key cap 111 is arranged on the side of the upper cover 11 away from the lower shell 12, and the control switch 21 is arranged on the side of the control panel 2 facing the upper cover 11. When the staff presses the key cap 111, the key cap 111 abuts against the control switch 21; the power adapter 3 is connected to the control panel 2 for transmitting current and signals.

[0057] In this way, pressing the keycap 111 makes the keycap 111 abut against the control switch 21, so that the control switch 21 transmits a control signal (for example, controlling the start and stop of the device) to the cable, and then the cable transmits it to the underwater device, which is convenient for controlling the underwater device on the water; the gap between the control board 2 and the power adapter 3 is not easy to generate heat accumulation, which facilitates the heat generated by the control board 2 when working and the heat generated by the power adapter 3 when working to spread in the air in the control cavity 13, and be transmitted to the outside through the heat sink 4 and the first heat dissipation window 121, so as to avoid excessive heat inside the control cavity 13 affecting the normal operation of internal components, and improve the stability and safety of the power control box during use.

[0058] See also Figure 2 In some embodiments, a touch screen (not shown) is further included. The touch screen is disposed on the upper cover 11 and is electrically connected to the control board 2 .

[0059] It is understandable that the position of the touch screen on the upper cover can be adjusted according to actual needs, as long as it can display relevant data and facilitate operation by the staff. No further details will be given here.

[0060] See also Figure 4 In some embodiments, the lower shell 12 is provided with a second heat dissipation window 122 , a heat dissipation element 4 is provided at the second heat dissipation window 122 , and the heat dissipation element 4 covers the second heat dissipation window 122 to close the control cavity 13 .

[0061] In this way, a second heat dissipation window 122 is opened below the power adapter 3, which can reduce the heat accumulation caused by the contact between the bottom of the power adapter 3 and the bottom surface of the lower shell 12, further enhance the heat dissipation performance of the power control box, reduce the influence of heat on the components in the control cavity 13, and further balance the air pressure in the control cavity 13 and the outside world, thereby avoiding deformation of the keycap 111 due to pressure difference, thereby affecting the normal operation of the staff; the heat dissipation element 4 can transfer the heat generated by the power adapter 3 during operation and the heat inside the control cavity 13 to the outside world in time, thereby avoiding the normal operation of the internal components affected by the heat accumulation inside the control cavity 13.

[0062] It is understandable that the shapes and areas of the first heat dissipation window 121 and the second heat dissipation window 122 can be flexibly adjusted according to actual needs, and no more examples are given here. In addition, the reinforcing ribs 14 can also separate the second heat dissipation window 122 into a plurality of heat dissipation holes. The shapes of the heat dissipation holes separated by the reinforcing ribs 14 from the first heat dissipation window 121 or the second heat dissipation window 122 can be adjusted according to actual needs. In this embodiment, the reinforcing ribs 14 connected to the first heat dissipation window 121 separate the first heat dissipation window 121 into a plurality of rectangular heat dissipation holes, and the reinforcing ribs 14 connected to the second heat dissipation window 122 separate the second heat dissipation window 122 into a plurality of hexagonal heat dissipation holes.

[0063] See also Figure 3 In some embodiments, the heat sink 4 is a heat sink fin, the side walls of the heat sink fin are respectively abutted against the inner wall of the control cavity 13, the heat sink fin is detachably connected to the lower shell 12, and the lower shell 12 extends in a direction away from the upper cover 11 to have a receiving groove 127 for accommodating the heat sink fin, and the second heat dissipation window 122 is opened on the receiving groove 127.

[0064] In this embodiment, the power adapter 3 is placed on the top surface of the heat sink fins, and the heat sink fins are connected to the lower shell 12 by bolts. The lower shell 12 is connected with a support portion 128, and the length of the support portion 128 is greater than the length of the accommodating groove 127, so that the lower shell 12 can be stably set on a plane.

[0065] In this way, the heat generated by the battery adapter when working and the heat accumulated inside the control cavity 13 can be transferred to the outside through the heat dissipation fins and the second heat dissipation window 122, thereby reducing the heat accumulation inside the control cavity 13 and extending the service life of the components inside the control cavity 13. The lower shell 12 extends the accommodating groove 127 in the direction away from the upper cover 11, so that a gap can be maintained between the power adapter 3 and the control board 2 while the heat dissipation element 4 is set, thereby improving the heat dissipation effect of the power control box and balancing the air pressure in the control cavity 13 and the outside.

[0066] It is understandable that the heat sink 4 is not limited to the heat sink fin structure, but can also be a heat sink made of a material with good thermal conductivity such as a copper plate or an aluminum plate, which can achieve the effect of transferring the heat generated by the power adapter 3 when working to the outside world. No further examples are given here.

[0067] See also Figure 5 In some embodiments, a second sealing ring 6 is further included. The second sealing ring 6 is disposed at the second heat dissipation window 122 and is located between the heat dissipation element 4 and the lower shell 12 to close the second heat dissipation window 122 .

[0068] The second sealing ring 6 is clamped on the bottom surface of the lower shell 12 . When the heat dissipating fins are installed inside the lower shell 12 by bolts, the heat dissipating fins are tightly abutted against the second sealing ring 6 , so that the heat dissipating fins are sealed and connected to the receiving groove 127 of the lower shell 12 .

[0069] In this way, the second sealing ring 6 can prevent liquid from entering the control cavity 13 through the receiving groove 127 , thereby improving the sealing and liquid-proof performance of the power control box and preventing external liquid from affecting the components in the control cavity 13 .

[0070] See also Figure 4 In some embodiments, the power control box further includes a first sealing ring 5, which is disposed between the upper cover 11 and the lower shell 12 to form a sealed connection.

[0071] In this embodiment, a groove (not shown in the figure) for accommodating the first sealing ring 5 is provided inside the lower shell 12 so that the first sealing ring 5 is snap-fitted with the lower shell 12 .

[0072] In this way, when the upper cover 11 and the lower shell 12 are buckled together, the two sides of the first sealing ring 5 are tightly in contact with the upper cover 11 and the lower shell 12 respectively, which can prevent external liquid from entering the control chamber 13 through the connection between the upper cover 11 and the lower shell 12, thereby affecting the normal operation of the internal components.

[0073] See also Figure 5-Figure 7 In some embodiments, the power control box also includes two sealing gaskets 7, which are respectively arranged at the first interface 123 and the second interface 124. When the power cord and the buoyancy line 10 are respectively connected to the first interface 123 and the second interface 124, the power cord and the buoyancy line 10 are respectively in contact with the sealing gaskets 7.

[0074] In this way, when the power cord and the buoyancy line 10 are respectively plugged into the first interface 123 and the second interface 124, under the action of the sealing gasket 7, it is difficult for external liquid to enter the control chamber 13 through the gap between the first interface 123 and the power cord and the gap between the buoyancy line 10 and the second interface 124.

[0075] It is understandable that the materials and specifications of the first sealing ring 5 , the second sealing ring 6 , and the sealing gasket 7 can be adjusted according to actual needs, and are not listed in detail here.

[0076] See also Figure 2 In some embodiments, a connecting block 112 is provided on the side of the upper cover 11 facing the lower shell 12, and a connecting groove 126 is provided on the side of the lower shell 12 facing the upper cover 11 corresponding to the connecting block 112, for clamping the upper cover 11 and the lower shell 12; a positioning block 113 is provided on the side of the upper cover 11 facing the lower shell 12, and a positioning groove 51 is provided on the side of the first sealing ring 5 facing the upper cover 11 corresponding to the positioning block 113, for clamping the upper cover 11 and the first sealing ring 5.

[0077] In this way, by inserting the connecting block 112 into the connecting groove 126 and the positioning block 113 into the positioning groove 51, the upper cover 11 and the lower shell 12 can be sealed and connected, so that liquid is not easy to enter the control cavity 13. At the same time, good ventilation and heat dissipation performance can be maintained through the first heat dissipation window 121 and the second heat dissipation window 122, thereby improving the safety and stability of the power control box during use.

[0078] It is understandable that a plurality of connecting blocks 112 and positioning blocks 113 may be provided, and the number and shape of the connecting blocks 112 and positioning blocks 113 may be flexibly adjusted according to actual needs, so as to achieve a sealed connection between the upper cover 11 and the lower shell 12 through the first sealing ring 5 .

[0079] See also Figure 8 The utility model also provides an underwater robot, including a robot body 9, a power cord, a buoyancy line 10 and a power control box, the power cord is connected to the first interface 123, one end of the buoyancy line 10 is connected to the second interface 124, and the other end is connected to the robot body 9, for transmitting electrical energy and / or control signals between the robot body 9 and the power control box.

[0080] Among them, the underwater robot is used for cleaning underwater environments (for example, swimming pools). The robot body 9 includes an outer shell (not shown in the figure), a filtering device (not shown in the figure), a flow guide device (not shown in the figure) and a power module (not shown in the figure). The filtering device, the flow guide device and the power module are respectively arranged inside the outer shell.

[0081] Furthermore, the shell is provided with a water inlet and a water outlet, the input end of the filtering device is connected with the water inlet, and the output end is connected with the water outlet, the diversion device includes a pump motor and a diversion pipe, which are used to drive the water flow from the water inlet to the filtering device for filtration, and then discharged into the water through the water outlet, and the power module includes a driving motor, a transmission machine, rollers and tracks, which are used to drive the shell to move underwater.

[0082] See also Figure 8 In some embodiments, the control board 2 is provided with a first communication module (not shown in the figure), and the underwater robot further includes a second communication module (not shown in the figure) and a power supply module (not shown in the figure), wherein the first communication module is connected to the second communication module and the power supply adapter 3 (see Figure 2 ) are connected to the power module via a buoyancy line 10.

[0083] In this way, the power control box set up on the shore can transmit current and control signals to the underwater robot through the buoyancy line 10, so as to control the underwater robot to make corresponding actions. Since gas exchange can occur between the outside world and the inside of the control chamber 13, the pressure between the outside world and the inside of the control chamber 13 is balanced, and heat is not easily accumulated in the control chamber 13. Therefore, the components inside the box body 1 can operate stably, and the keycap 111 is not easily deformed due to pressure difference or high temperature. Therefore, when the staff presses the keycap 111, the keycap 111 can sensitively abut against the control switch 21.

[0084] 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.
