[0036] Example 1
[0037] Please refer to Figures 1 to 5 This embodiment provides a motor device suitable for an underwater robot, suitable for underwater environments, including: a motor 1, a motor heat-conducting bracket 2 and a heat-conducting housing 3.
[0038] Specifically, the motor 1 is fixedly arranged in the motor thermal bracket 2, for example, it can be fixed in the motor thermal bracket 2 by screws. The shape of the motor thermal bracket 2 is adapted to the motor 1, so that the motor thermal bracket 2 at least wraps a portion of the motor 1, that is, it can be partially wrapped or completely wrapped. By wrapping the motor 1, the heat generated by the motor 1 can be transferred to the motor thermal bracket 2, thereby reducing the temperature of the motor 1. A heat-conducting medium is also provided between the motor 1 and the motor thermal bracket 2 to make the heat conduction efficiency higher. The heat-conducting medium is illustratively thermally conductive silicone or thermally conductive silicone grease.
[0039] The motor heat-conducting bracket 2 is fixedly mounted in the heat-conducting housing 3, with the outer wall of the heat-conducting housing 3 at least partially exposed to the water. A heat-conducting inner wall 4 is formed in the heat-conducting housing 3 at a position corresponding to the motor heat-conducting bracket 2. The shape of the heat-conducting inner wall 4 is adapted to the heat-conducting bracket 2. The heat-conducting inner wall 4 contacts the outer wall of the heat-conducting bracket 2 via a heat-conducting medium, thereby allowing heat from the motor 1 to be transferred to the external water through the heat-conducting bracket 2 and the heat-conducting inner wall 4.
[0040] Understandably, in order to maximize the contact area between the heat-conducting housing 3 and the motor heat-conducting bracket 2, thereby improving the efficiency of heat conduction, the present application has designed a heat-conducting inner wall 4 on the heat-conducting housing 3 that is shaped to match the motor heat-conducting bracket 2. Due to this shape fit, the inner wall of the heat-conducting inner wall 4 can maximize contact with the motor heat-conducting bracket 2, thereby achieving efficient heat transfer. The side of the heat-conducting inner wall 4 away from the motor heat-conducting bracket 2, that is, its outer wall, contacts the water in the outside world, thereby quickly transferring heat to the water, thereby reducing the temperature inside the motor 1 and the heat-conducting housing 3.
[0041] In practical applications, the number of motors 1 in the heat-conducting housing 3 can be one or more, and the number of motor heat-conducting brackets 2 is adapted to the number of motors 1 .
[0042] In this embodiment, please refer to Figures 3 to 5The motor heat-conducting bracket 2 can be wrapped around the lower part of the motor 1 and the side of the motor 1 located on its output shaft 11. The heat-conducting housing 3 is formed with a groove 5 at the position corresponding to the motor heat-conducting bracket 2, and the inner wall of the groove 5 is the heat-conducting inner wall 4. The inner wall of the groove 5 contacts the part of the motor heat-conducting bracket 2 wrapped around the lower part of the motor 1 through the heat-conducting medium. It can be seen that this design allows most of the heat of the motor 1 to be transferred from its lower part to the motor heat-conducting bracket 2, and finally transfers the heat to the external water through the heat-conducting inner wall 4 of the heat-conducting housing 3. Compared with the flat heat-conducting housing 3, the setting of the groove 5 increases the contact area between the heat-conducting housing 3 and the motor heat-conducting bracket 2, thereby improving the efficiency of heat conduction. In addition, since the output shaft 11 of the motor 1 needs to rotate continuously in the working state, a large amount of heat will be generated at the output shaft 11 of the motor 1. The motor heat-conducting bracket 2 wraps the motor 1 on the side of its output shaft 11, which can improve the heat dissipation efficiency at the output shaft 11, thereby better reducing the temperature of the motor 1.
[0043] Furthermore, a fixing member 6 is provided on the upper portion of the motor 1, and the fixing member 6 is connected to the motor heat-conducting bracket 2, for example, by screws, so as to fix the motor 1 in the motor heat-conducting bracket 2. Preferably, a protective pad 7 is provided between the motor 1 and the fixing member 6 to prevent the motor 1 from being squeezed and damaged by the fixing member 6.
[0044] In this embodiment, please refer to Figures 1 to 3 The heat-conducting housing 3 may be recessed internally to form one or more recessed surfaces 8, and / or may protrude outward to form one or more protruding surfaces (not shown). The figure shows the recessed surfaces 8, but the number of recessed surfaces 8 can be one or more, and the specific shape of the recessed surfaces 8 can also be designed according to actual needs. The figure shows a strip-shaped recessed surface 8. It can be understood that both the recessed surface 8 and the protruding surface can increase the contact area between the heat-conducting housing 3 and the external water, thereby improving the efficiency of the heat-conducting housing 3 in transferring heat to the water.
[0045] In this embodiment, please refer to Figures 1 to 3 The thermally conductive housing 3 may include a first housing 31 and a second housing 32 connected to each other, sealed by a thermally conductive medium. Specifically, the first and second housings 31, 32 may be connected via screws. Multiple receiving grooves 9 are defined at the junction of the edges of the first and second housings 31, 32, each containing the thermally conductive medium. Spacing between the different receiving grooves 9 allows for multi-layered waterproofing, enhancing the thermally conductive housing 3's waterproof performance.
[0046] Preferably, at least one of the first shell 31 and the second shell 32 is a metal shell, such as an aluminum alloy shell or a copper alloy shell with high thermal conductivity. Due to the excellent thermal conductivity of the metal shell, heat can be quickly transferred to the water.
[0047] In one embodiment, the motor heat-conducting bracket 2 is also a metal bracket, for example, a bracket made of aluminum alloy material or copper alloy material.
[0048] Example 2
[0049] Please refer to Figure 6 and Figure 7 This embodiment provides an underwater robot, including a motor device suitable for an underwater robot as described in Example 1, as well as a housing 10, a power module and a motion component 12.
[0050] Specifically, the heat-conducting housing 3 is disposed within an outer shell 10. The outer shell 10 is provided with a water inlet 101 that connects the outside world to the interior. During underwater operations, water from the outside world can enter the inner portion of the outer shell 10 through the water inlet 101 and exchange heat with the heat-conducting housing 3. The power module is electrically connected to the motor 1 to supply power to the motor 1. The output shaft 11 of the motor 1 is drivingly connected to the motion assembly 12 to drive the motion assembly 12, enabling the underwater robot to achieve underwater movement based on the motion assembly 12.
[0051] In summary, the present invention proposes a motor device suitable for an underwater robot and an underwater robot including the same. The motor device, through a rational structural design, allows the heat generated by the motor to be quickly transferred to the external water through the motor's heat-conducting bracket and heat-conducting inner wall, effectively reducing the motor's operating temperature. Based on this motor device suitable for an underwater robot, the present invention improves the motor's heat dissipation capabilities, effectively suppresses internal heating during continuous operation, avoids thermal degradation of the device's performance, and extends the device's service life, providing a superior user experience.
