[0033] Example 1

[0034] like Figures 1 to 3 As shown, the power conversion device provided in Embodiment 1 of this utility model includes a circuit board 20 and an electronic device 10, wherein the electronic device 10 is disposed on the circuit board 20; it also includes a housing 30; the housing 30 forms a receiving cavity 31 for accommodating the circuit board 20 and the electronic device 10, the receiving cavity 31 forms at least a through groove 32 facing one end face, the area of ​​the through groove 32 is at least not less than the area of ​​the circuit board 20 occupied by the electronic device 10, and the opening of the through groove 32 faces the electronic device 10.

[0035] Specifically, by placing the electronic device 10 and the circuit board 20 within the receiving cavity 31 of the housing 30, the housing 30 protects the circuit board 20 and the electronic device 10, making the overall power conversion an independent unit. Furthermore, by providing a through slot 32 on at least one side of the receiving cavity 31 with an area not less than the area occupied by the electronic device 10 on the circuit board 20, a sufficiently large heat dissipation channel for the electronic device 10 is formed, ensuring the heat dissipation effect of the electronic device 10 without increasing economic costs.

[0036] Among them, the electronic components 10 are soldered to the circuit board 20 according to the preset wiring and other methods to form a voltage drop effect, that is, to perform power supply voltage conversion; the electronic components 10 include chips, resistors and capacitors, etc.

[0037] The housing 30 forms a cavity 31 for accommodating the circuit board 20 and the electronic device 10. The housing 30 can protect the circuit board 20 and the electronic device 10 as a whole, and prevent them from being affected by the external environment.

[0038] The cavity 31 has a through-slot 32 on at least one side, and the area of ​​the through-slot 32 is not less than the area occupied by the electronic device 10 on the circuit board 20. This ensures that the through-slot 32 can form a sufficiently large heat dissipation channel, thereby ensuring rapid heat dissipation for the electronic device 10 on the circuit board 20. It is worth mentioning that the through-slot 32 is provided on at least one side of the cavity 31, preferably on both sides. Since electronic devices 10 are located on both sides of the circuit board 20, to ensure that both electronic devices 10 can dissipate heat, exposed through-slots 32 are provided on both sides, allowing the electronic devices 10 inside the housing 30 to directly contact external cold air, thereby achieving a better heat dissipation effect. It is also worth mentioning that the opening area of ​​the through-slot 32 is adapted to the area occupied by the electronic device 10 on the circuit board, meaning that the heat generated by the electronic device 10 during operation can be dissipated through the opening of the through-slot 32, ensuring a good heat dissipation effect.

[0039] The opening of the through slot 32 faces the electronic device 10, which helps to reduce the heat dissipation path of the electronic device 10 facing the opening of the through slot 32, and achieves faster heat dissipation.

[0040] like Figure 4 As shown, by way of example, the housing 30 includes a first cover 33 and a second cover 34; through grooves 32 are formed on the first cover 33 and the second cover 34, and a fixing part 35 is disposed on the inner edge of at least one of the through grooves 32, and the circuit board 20 can be snapped onto one side of the fixing part 35.

[0041] Specifically, the first cover 33 and the second cover 34 are closed to form the shell 30. Both the first cover 33 and the second cover 34 have through grooves 32. The inner edge of the through groove 32 of the first cover 33 is provided with a fixing part 35. The circuit board 20 can be snapped onto the fixing part 35 of the through groove 32 of the first cover 33, and the second cover 34 is closed onto the first cover 33 to achieve overall protection of the circuit board 20 and the electronic device 10.

[0042] The first cover and the second cover are rectangular plates. Each rectangular plate has a through groove 32 at its center and a fixing part 35 at its inner edge to ensure that the circuit board 20 can be snapped and fixed, and to protect the circuit board 20 and electronic components 10 at the center of the first cover and the second cover, so as to ensure sufficient protection and good heat dissipation.

[0043] For example, the area of ​​the through groove 32 formed on the first cover 33 is adapted to the size of the circuit board 20, and the area of ​​the through groove 32 formed on the second cover 34 is adapted to the size of the electronic device 10 occupying the circuit board 20.

[0044] Specifically, the first cover is located at the bottom; the area of ​​the through groove 32 formed on the first cover 33 is adapted to the size of the circuit board 20, that is, after the circuit board 20 is snapped into the through groove 32 of the first cover 33, it can ensure that the electronic device 10 on the lower end of the circuit board 20 can form a heat dissipation channel through the through groove 32 to avoid interference problems; the second cover is located on the upper side; the second cover is closed on the first cover, and the through groove 32 of the second cover can ensure that the electronic device 10 on the upper end has a large heat dissipation channel.

[0045] It is worth mentioning that the area of ​​the through slot 32 can be determined according to the number and area of ​​the electronic devices 10 configured on both ends of the actual circuit board 20, as long as it does not interfere with the electronic devices 10 and has a sufficiently large heat dissipation channel.

[0046] For example, the fixing part 35 includes a protruding edge disposed circumferentially along the inner side edge of the through groove 32.

[0047] Specifically, the fixing part 35 on the first cover 33 can have a protruding edge circumferentially arranged along the inner edge of the through groove 32 of the first cover 33. The circuit board 20 can be precisely engaged with the inner side of the protruding edge, thereby limiting and fixing the circuit board 20. It is worth mentioning that the protruding edge should be positioned away from the location of the electronic device 10 to avoid interference with the electronic device 10; that is, it is best if the protruding edge can be precisely engaged with the edge of the circuit board 20.

[0048] The fixing part 35 includes protruding edges at four corners along the inner side of the through groove 32. The circuit board 20 can engage with the protruding edges at the four corners to ensure a secure engagement. Notably, the height of the protruding edges is flush with the end face of the first cover 33 when the circuit board 20 is engaged with it.

[0049] For example, the first cover 33 and the second cover 34 are detachably connected.

[0050] Specifically, the first cover 33 and the second cover 34 are detachably connected. The first cover 33 and the second cover 34 are provided with corresponding fixing holes. Bolts are used to pass through the fixing holes to fasten the first cover 33 and the second cover 34. The first cover 33 and the second cover 34 can be disassembled by loosening the bolts. The operation is simple and convenient and highly practical.

[0051] The first cover 33 and the second cover 34 can be detachably connected, or they can be fixedly connected by adhesive, or they can be detached by setting locking buckles on the outside of the first cover 33 and the second cover 34.

[0052] like Figure 8As shown, by way of example, the cavity 31 further includes a limiting part 36; the limiting part 36 is located inside the through groove 32 and is used to limit the position of the circuit board 20 within the cavity 31.

[0053] Specifically, by setting a limiting part 36 in the receiving cavity 31, the circuit board 20 can be snapped onto the limiting part 36, which can both limit the installation position of the circuit board 20 and ensure that the first cover 33 and the second cover 34 can be completely closed after the circuit board 20 is installed in place.

[0054] For example, the end of the housing 30 is provided with a through groove 37, one end of the through groove 37 faces the output end of the circuit board 20, and the other end of the through groove 37 extends outward.

[0055] Specifically, by providing a cable routing groove 37 at the end of the housing 30, with one end of the cable routing groove 37 facing the output end of the circuit board 20 and the other end of the cable routing groove 37 extending outward, the cable routing groove 37 can guide the external connection wires of the circuit board 20, thus facilitating the routing of the wires.

[0056] Preferably, a wire channel 37 is provided at both ends of the housing 30, that is, a wire channel 37 for the incoming wire of the circuit board 20 at one end and a wire channel 37 for the outgoing wire of the circuit board 20 at the other end.

[0057] The size of the cable tray 37 can be selected according to the actual size of the inlet and outlet connecting cables to ensure that the connecting cables can be transported better.

[0058] For example, the depth of the aforementioned through groove 32 is not less than the thickness of the aforementioned electronic device 10.

[0059] Specifically, by setting the depth of the through groove 32 to be no less than the thickness of the electronic device 10, the electronic device 10 can be located inside the through groove 32, thereby achieving all-round protection for the electronic device 10 and avoiding damage caused by external influences.

[0060] Preferably, the thickness of the through groove 32 is greater than the thickness of the electronic device 10 to ensure that the electronic device 10 is completely located inside the through groove 32, thus ensuring a protective effect. It is worth mentioning that when both the first cover and the second cover have through grooves 32, and when the electronic device 10 is soldered to both sides of the circuit board 20, the dimensions of the through groove 32 of the first cover and the through groove 32 of the second cover are preferably the sum of the thickness of the largest electronic device 10 on both sides and the thickness of the circuit board 20, to ensure a good containment effect and to avoid affecting the electronic device 10, etc.

[0061] like Figures 1 to 8As shown above, the installation steps for the power conversion device using this utility model include:

[0062] First, the electronic component 10 is soldered onto the circuit board 20, and its power conversion function is tested to confirm that the power conversion function is normal. The lower end face of the electronic component 10 and the circuit board 20 is installed in the receiving cavity of the first cover 33 (lower side), so that the circumferential edge of the circuit board 20 can be precisely engaged with the fixing part 35 on the inner edge of the through groove 32, and the limiting part 36 provided on the inner side wall of the through groove 32 can limit the position of the circuit board 20, ensuring that the lower end of the electronic component 10 does not protrude from the through groove 32, while ensuring that the upper end face of the circuit board 20 is flush with the upper end face of the first cover 33. The second cover 34 is placed on the upper side of the first cover 33, ensuring that the first cover 33 and the second cover 34 are flush, and the electronic components 10 on the upper side of the circuit board 20 can all be ventilated and cooled through the upper through groove 32. Finally, the first cover 33 and the second cover 34 are fixed by bolts passing through the corresponding fixing holes of the first cover 33 and the second cover 34. It is worth mentioning that when arranging the electronic device 10 and the circuit board 20 as a whole, the incoming and outgoing lines at both ends of the circuit board 20 can be simultaneously matched with the wiring grooves at both ends of the housing 30 to ensure that the wiring setup of the power conversion device can be completed synchronously after the first cover 33 and the second cover 34 are securely connected.

[0063] A surgical robot includes the aforementioned power conversion device.

[0064] Specifically, the surgical robot includes a power conversion device that can convert the mains voltage into the voltage value required by the surgical robot, providing a stable power supply for the surgical robot.

[0065] Example 2

[0066] The difference between this embodiment and Embodiment 1 is that the housing 30 includes a first cover 33 and a second cover 34; the first cover 33 forms a through groove 32, and a fixing part 35 is disposed on the inner edge of the through groove 32, and the circuit board 20 can be snapped onto one side of the fixing part 35.

[0067] Specifically, the first cover 33 is located on the lower side; by forming a through groove 32 on the lower side of the first cover 33, and configuring a fixing part 35 on the inner edge of the through groove 32, the circuit board 20 is fixed on the inner side of the fixing part 35, and heat can be conducted through the through groove 32 on the lower side, thereby achieving the protection effect of the power conversion module and having a good heat dissipation effect.

[0068] Preferably, the circuit board 20 is configured with a high-power electronic device 10 on the side facing the first cover 33, so as to ensure that the high-power electronic device 10 can achieve a faster heat dissipation effect through the through slot 32 of the first cover 33 during operation.

[0069] Example 3

[0070] The difference between this embodiment and Embodiment 1 is that the opening of the through groove 32 facing the circuit board 20 is sealed with fixing glue or insulating glue.

[0071] Specifically, by sealing the opening of the through groove 32 toward the circuit board 20 with fixing adhesive or insulating adhesive, the circuit board 20 and electronic components 10 are secondary fixed and protected, thereby improving the fixing and protection effects.

[0072] Among them, sealing insulating adhesive is preferred to increase the insulation performance of the overall power conversion module.

[0073] In summary, the power conversion device and surgical robot provided by this utility model, by placing the electronic device 10 and the circuit board 20 in the receiving cavity 31 of the housing 30, the housing 30 protects the circuit board 20 and the electronic device 10, and by forming a sufficiently large heat dissipation channel for the electronic device 10 through a through groove 32 provided on at least one side of the receiving cavity 31 with an area not less than the area occupied by the electronic device 10 on the circuit board 20, the heat dissipation effect of the electronic device 10 is guaranteed.
