Description

Technical Field

[0001] This application relates to the field of robot heat dissipation technology, and in particular to an energy-saving heat dissipation mechanism and robot. Background Technology

[0002] With the rapid development of the humanoid robot industry, and as the complexity of humanoid robot movements and the loads they bear continue to increase, the heat generated by the joint motors is also increasing. Therefore, it is urgent to improve the performance of cooling modules used to dissipate heat from the joint motors.

[0003] In existing technologies, the cooling module itself consumes power. For example, the cooling module needs to use pumps, compressors, or motors to circulate and cool the coolant. Thus, on the one hand, since there are many joint motors, there are also many corresponding cooling modules, which increases the overall power consumption of the robot and is not conducive to the low-power design of the robot. On the other hand, it increases the noise and vibration of the robot during operation, which is not conducive to the quiet design of the robot. Utility Model Content

[0004] Therefore, it is necessary to provide an energy-saving heat dissipation mechanism and robot to solve the problems of high overall power consumption and poor quietness of existing robots. This application provides an energy-saving heat dissipation mechanism and robot.

[0005] The energy-saving heat dissipation mechanism provided in this application includes a foot base, a spring-loaded component, a connecting rod assembly, and a heat dissipation device. The heat dissipation device includes a piston and a housing. A liquid working fluid is disposed inside the housing. The piston and the inner wall of the housing are in a movable sealing fit. The connecting end of the spring-loaded component is connected to the foot base, and the movable end of the spring-loaded component is in a spring-loaded fit with the foot base. One end of the connecting rod assembly is connected to the movable end of the spring-loaded component, and the other end is connected to the piston. When the movable end of the spring-loaded component undergoes elastic deformation towards the foot base under external pressure, the spring-loaded component can drive the piston to move in a first direction through the connecting rod assembly. When the movable end of the spring-loaded component is not subjected to external pressure, the spring-loaded component can drive the piston to move in a second direction through the connecting rod assembly. The first and second directions are opposite. When the piston moves towards one of the first and second directions, the liquid working fluid can be phased into a gaseous working fluid to absorb the heat generated by the power element corresponding to the housing. When the piston moves towards the other of the first and second directions, the piston can discharge the gaseous working fluid inside the housing.

[0006] In one embodiment, the linkage assembly includes a first linkage, one end of which is hinged to the movable end of the spring member, and the other end of which is hinged to the piston portion extending out of the housing.

[0007] In one embodiment, the linkage assembly further includes a second linkage, and there are multiple heat dissipation devices arranged in a straight line. The second linkage is connected in series with the piston parts of the multiple heat dissipation devices to drive the multiple piston parts to move synchronously. One end of the first linkage is hinged to the movable end of the spring member, and the other end is hinged to one end of the second linkage.

[0008] In one embodiment, the second link includes a main rod and a plurality of branch rods. One end of the main rod is hinged to the first link, and one end of each branch rod is fixedly connected to the main rod, while the other end is connected to the piston portion of the corresponding heat dissipation device.

[0009] In one embodiment, the heat dissipation device further includes a first one-way valve and a second one-way valve. The first one-way valve is disposed within the housing to divide the interior of the housing into a cooling chamber and a moving chamber. The power element is disposed within the cooling chamber, and the liquid working fluid and the heating end of the power element are in direct contact. A piston is movably disposed within the moving chamber and divides the moving chamber into a non-connected vaporization chamber and a mating chamber. The cooling chamber can be unidirectionally connected to the vaporization chamber through the first one-way valve, and the vaporization chamber of the housing can be unidirectionally connected to the atmospheric environment through the second one-way valve. When the piston moves away from the first one-way valve, the vaporization chamber expands, and the liquid working fluid in the cooling chamber can enter the vaporization chamber through the first one-way valve and change phase to gaseous working fluid. When the piston moves closer to the first one-way valve, the vaporization chamber is compressed, and the gaseous working fluid in the vaporization chamber can enter the atmospheric environment through the second one-way valve.

[0010] In one embodiment, there are two housings, and the piston, the first one-way valve, the second one-way valve and the housing are arranged in a one-to-one correspondence. The two housings share a cooling chamber, and one or more power components are arranged in the cooling chamber. The cooling chamber can be connected to the corresponding vaporization chamber through the corresponding first one-way valve. The connecting rod assembly can drive the two pistons to move synchronously in the same direction.

[0011] In one embodiment, the spring is a spring sheet, one end of which is connected to the bottom of the foot seat and the other end protrudes from the bottom of the foot seat. The end of the spring sheet protruding from the bottom of the foot seat is defined as the movable end of the spring sheet. The movable end of the spring sheet can elastically deform in the direction of approaching or moving away from the foot seat.

[0012] In one embodiment, the spring includes a pressure plate and a compression spring. The connecting end of the pressure plate is hinged to the bottom of the foot seat. One end of the compression spring is connected to the bottom of the foot seat, and the other end is connected to the movable end of the pressure plate. The movable end of the pressure plate can rotate toward the foot seat to compress the compression spring. Alternatively, the compression spring can push the movable end of the pressure plate to move away from the foot seat and reset itself.

[0013] In one embodiment, the bottom of the foot seat is provided with a receiving groove with an opening facing the ground, a pressure plate is hinged to the side wall of the receiving groove, one end of a compression spring is connected to the top wall of the receiving groove, and the other end is connected to the pressure plate.

[0014] This application also provides a robot that includes the energy-saving heat dissipation mechanism described in any of the above embodiments.

[0015] Compared with existing technologies, the energy-saving heat dissipation mechanism and robot provided in this application directly convert impact energy into heat dissipation power through the mechanical linkage of the spring-loaded component, connecting rod assembly, and piston, without requiring additional power consumption. Simultaneously, the buffering effect of the spring-loaded component reduces structural vibration caused by motion impact, and combined with the quiet characteristics of phase-change heat dissipation, the overall system operating noise is significantly reduced.

Detailed Implementation

[0021] Please see Figures 1-3In one embodiment, the energy-saving heat dissipation mechanism includes a foot seat 100, a spring-loaded component 200, a connecting rod assembly 300, and a heat dissipation device 400. The heat dissipation device 400 includes a piston 410 and a housing 420. The housing 420 contains a liquid working fluid. The piston 410 is movably disposed in the housing 420 and is in a movably sealed fit with the inner wall of the housing 420.

[0022] It should be noted that the foot seat 100 is the walking part of the robot, similar to the foot of a human body. In order to facilitate the deformation of the spring member 200, the spring member 200 is located at the bottom of the foot seat 100 to facilitate the compression and expansion of the spring member 200.

[0023] like Figure 1 and Figure 2 As shown, the connecting end of the spring-loaded component 200 is connected to the foot seat 100, the movable end of the spring-loaded component 200 and the foot seat 100 are spring-loaded together, one end of the connecting rod assembly 300 is connected to the movable end of the spring-loaded component 200, and the other end is connected to the piston part 410 of the heat dissipation device 400.

[0024] When the movable end of the spring-loaded component 200 undergoes elastic deformation towards the footrest 100 under external pressure (mainly the pressure exerted by the robot during walking), that is, when the robot uses its own weight to apply pressure to the movable end of the spring-loaded component 200 during walking, causing the robot's footrest 100 to press down and contact the ground, the movable end of the spring-loaded component 200 undergoes elastic deformation. At this time, the movable end of the spring-loaded component 200 can drive the piston 410 to move in the first direction via the linkage assembly 300.

[0025] When the movable end of the spring-loaded component 200 is not subjected to external pressure, that is, when the robot lifts its leg and causes the foot seat 100 to lift, the movable end of the spring-loaded component 200 can drive the piston part 410 to move in the second direction through the linkage assembly 300.

[0026] It should be noted that the piston part 410 moves within the housing 420 along the axial direction of the housing 420. Obviously, the axial direction of the housing 420 has two ends. Therefore, the direction when moving towards one end of the housing 420 is defined as the first direction. Similarly, the direction when moving towards the other end of the housing 420 is defined as the second direction.

[0027] It should be noted that the spring-loaded component 200 is an energy storage element that converts mechanical impact into elastic potential energy. Specifically, it can be implemented using a disc spring or a bow-shaped spring sheet. It absorbs the impact energy from the foot through its own deformation and converts it into the reciprocating motion power of the connecting rod assembly 300. The connecting rod assembly 300 is a rigid connection mechanism that transmits mechanical motion. Specifically, it can be implemented using a hinged metal rod, converting the deformation of the spring-loaded component 200 into the stroke of the piston part 410. The piston part 410 is a moving component that forms a sealed cavity with the housing 420. Specifically, it can be implemented using a chrome-plated aluminum alloy piston. Its reciprocating motion changes the internal volume of the housing 420 to control the phase change process of the working fluid. The housing 420 is a container that seals the liquid working fluid. Specifically, it can be implemented using a copper-aluminum composite material, with an internal capillary structure to promote contact between the liquid working fluid and the power element 800.

[0028] The first and second directions are opposite, and when the piston portion 410 moves toward one of the first and second directions, the liquid working fluid can be phase-changed into a gaseous working fluid to absorb the heat generated by the power element 800 (including, but not limited to, IGBT modules, motors, and chips) corresponding to the housing 420. When the piston portion 410 moves toward the other of the first and second directions, the piston portion 410 can discharge the gaseous working fluid inside the housing 420.

[0029] It should be noted that the power element 800 can be in direct contact with the liquid working fluid inside the housing 420, or it can transfer heat through the wall of the housing 420.

[0030] Specifically, taking the example of the piston 410 moving in the first direction, where the liquid working fluid undergoes a phase change and absorbs heat, and the piston 410 moving in the second direction, where it discharges the gaseous working fluid, as an example, when the robot's foot contacts the ground and bears external pressure, the movable end of the spring-loaded component 200 undergoes elastic deformation towards the foot seat 100. At this time, the spring-loaded component 200 pushes the piston 410 of the heat dissipation device 400 to move in the first direction via the linkage assembly 300, causing the liquid working fluid to vaporize within the housing 420 to absorb the heat generated by the power element 800. When the external pressure is released, the movable end of the spring-loaded component 200 resets under its own elasticity and drives the piston 410 to move in the second direction, discharging the gaseous working fluid from the housing 420, thus completing the cyclic heat dissipation process of the working fluid. This solution directly responds to changes in external pressure through the elastic deformation of the spring-loaded component 200, without relying on external driving energy.

[0031] Conversely, taking the piston 410 moving in the second direction, where the liquid working fluid undergoes a phase change and absorbs heat, and the piston 410 moving in the first direction, where it discharges the gaseous working fluid, as an example: When the robot's foot contacts the ground and bears external pressure, the movable end of the spring-loaded member 200 undergoes elastic deformation towards the foot seat 100. At this time, the spring-loaded member 200 pushes the piston 410 of the heat dissipation device 400 to move in the second direction via the connecting rod assembly 300, causing the liquid working fluid to vaporize within the housing 420 to absorb the heat generated by the power element 800. When the external pressure is released, the movable end of the spring-loaded member 200 resets under its own elasticity and drives the piston 410 to move in the first direction, discharging the gaseous working fluid from the housing 420, thus completing the circulating heat dissipation process of the working fluid.

[0032] Compared with existing technologies, this solution directly converts impact energy into heat dissipation power through the mechanical linkage of the spring-loaded component 200, the connecting rod assembly 300, and the piston part 410, without requiring additional power consumption. At the same time, the buffering effect of the spring-loaded component 200 reduces structural vibration caused by motion impact, and combined with the quiet characteristics of phase change heat dissipation, the overall system operating noise is significantly reduced.

[0033] In one embodiment, the spring element 200 is in the form of a spring sheet. One end of the spring sheet is connected to the bottom of the foot seat 100, and the other end protrudes from the bottom of the foot seat 100. The end of the spring sheet protruding from the bottom of the foot seat 100 is defined as the movable end of the spring sheet. When the foot seat 100 of the robot contacts the ground, the movable end of the spring sheet undergoes elastic bending deformation towards the bottom of the foot seat 100 under pressure. When the foot seat 100 of the robot leaves the ground, the movable end of the spring sheet can be reset. That is, the movable end of the spring sheet can undergo elastic deformation towards the foot seat 100 or away from it.

[0034] It should be noted that the linkage assembly 300 is connected to the movable end of the spring.

[0035] Specifically, the spring can be made of metal or hard plastic, and it can be welded to the foot base 100, or it can be glued or snapped onto the foot base 100.

[0036] In another embodiment, such as Figure 1 and Figure 2As shown, the spring-loaded component 200 includes a pressure plate 210 and a compression spring 220. The connecting end of the pressure plate 210 is hinged to the bottom of the foot seat 100. One end of the compression spring 220 is connected to the bottom of the foot seat 100, and the other end is connected to the movable end of the pressure plate 210. When the robot's foot seat 100 contacts the ground, the compression spring 220 undergoes elastic compression deformation towards the bottom of the foot seat 100 under pressure. At this time, the movable end of the pressure plate 210 moves synchronously with the compression spring 220. When the robot's foot seat 100 leaves the ground, the compression spring 220 resets, so that the movable end of the pressure plate 210 can reset synchronously. That is, the movable end of the pressure plate 210 can rotate towards the foot seat 100 to compress the compression spring 220, or the compression spring 220 can push the movable end of the pressure plate 210 to move away from the foot seat 100 and reset itself (the compression spring 220).

[0037] It should be noted that the connecting rod assembly 300 is connected to the movable end of the pressure plate 210.

[0038] Among them, the pressure plate 210 refers to a rigid plate-shaped component with a connecting end and a movable end. Specifically, it can be made of metal or high-strength composite material. Its hinged design allows rotation around the axis to change the position of the movable end, thereby realizing mechanical transmission linked with external pressure.

[0039] Among them, the compression spring 220 refers to a helical spring that provides linear elastic force. It can be made of stainless steel or carbon steel. By compressing and storing energy and releasing deformation energy, it provides driving force for the reset of the movable end of the pressure plate 210.

[0040] The hinge at the bottom of the foot seat 100 means that the pressure plate 210 is rotatably connected to the foot seat 100 by means of a pivot or pin. Specifically, a hinge structure with a self-lubricating bearing can be used to achieve low-friction rotation.

[0041] Compared with existing technologies, the combined design of pressure plate 210 and compression spring 220 distributes the load to the hinge point and spring, improving structural reliability.

[0042] Through the above technical solution, this application utilizes the leverage effect of the pressure plate 210 to amplify the effect of external pressure on the compression spring 220, achieving more precise elastic deformation control. Simultaneously, the linear elastic characteristics of the spring ensure a smooth and shock-free reset process. This structure converts the ground reaction force during robot movement into the driving force of the piston 410 of the heat dissipation device 400, achieving cooling circulation without additional power, reducing system power consumption and mechanical vibration noise.

[0043] Furthermore, in one embodiment, as Figure 1 and Figure 2As shown, the bottom of the foot seat 100 is provided with a receiving groove 110 with an opening facing the ground. The receiving groove 110 can be formed by cutting the bottom of the foot seat 100, or multiple pads can be provided at the bottom of the foot seat 100, with the receiving groove 110 formed between adjacent pads. The pressure plate 210 is hinged to the side wall of the receiving groove 110, and one end of the compression spring 220 is connected to the top wall of the receiving groove 110 away from the ground, and the other end is connected to the pressure plate 210.

[0044] The top and side walls of the receiving groove 110 refer to the groove structure formed at the bottom of the foot seat 100. Specifically, it can be designed as a rectangular or arc-shaped inner cavity to accommodate the spatial displacement of the pressure plate 210 during rotation and avoid interference with the external structure.

[0045] This design improves the maximum stroke of the compression spring 220, which in turn facilitates energy storage in the spring-loaded component 200. Furthermore, the compression spring 220 is positioned within the receiving groove 110, ensuring it is fully contained within the groove when compressed. This prevents the pressure plate 210 from protruding from the bottom plane of the footrest 100, thus avoiding any impact on the walking stability of the footrest 100 from the spring-loaded component 200. Additionally, the enclosed design of the receiving groove 110 prevents dust or foreign objects from entering the hinge area, reducing the risk of wear on the moving parts.

[0046] Furthermore, in one embodiment, such as Figure 1 and Figure 2 As shown, the top wall of the receiving groove 110 is provided with an installation inclined surface 120, and the compression spring 220 is connected to the installation inclined surface 120. When the compression spring 220 is reset, the installation inclined surface 120 and the pressure plate 210 are arranged in parallel.

[0047] This helps to increase the pressure exerted by the pressure plate 210 on the compression spring 220.

[0048] In one embodiment, the linkage assembly 300 includes a first linkage 310, one end of which is hinged to the movable end of the spring-loaded member 200, and the other end is hinged to the piston portion 410 extending out of the housing 420. When the spring-loaded member 200 swings around its fixed end (connected to the foot seat portion 100), the spring-loaded member 200 can drive the first linkage 310 to perform a compound motion, and cause the piston portion 410 to move linearly along the axial direction of the housing 420.

[0049] The first connecting rod 310 is a rigid rod used to transmit the motion relationship between the spring-loaded component 200 and the piston part 410. It can be made of metal or high-strength composite material and is connected at both ends by a hinge to achieve rotational freedom. A hinge is a connection method that allows two components to rotate relative to each other around the same axis. This can be achieved using a pin and bushing structure, for example, by providing a lug with a through hole at the connection point and fixing it with a pin. The end of the piston part 410 extending out of the housing 420 refers to the structure formed by the piston rod or its extension extending outward from the inside of the housing 420. This can be achieved using a stepped shaft or flange structure to provide an external connection interface.

[0050] Specifically, when the movable end of the spring-loaded component 200 undergoes elastic deformation under external pressure, the first connecting rod 310 transmits linear displacement to the piston portion 410 through the relative rotation of the hinge points at both ends, driving it to slide axially within the housing 420. Because the hinge structure allows for angular changes between the movable end of the spring-loaded component 200 and the piston portion 410, stress concentration caused by rigid connections is avoided during movement. When the pressure is removed, the spring-loaded component 200 pulls the first connecting rod 310 in the reverse direction during its reset process, causing the piston portion 410 to move in the opposite direction. This bidirectional motion, through the reciprocating motion of the piston portion 410, promotes a phase change in the liquid working fluid, absorbing heat and achieving continuous heat dissipation for the power element 800.

[0051] Compared to existing technologies, traditional power transmission mechanisms often employ fixed connections or sliding fits, which are prone to component wear due to assembly errors or deviations in motion trajectory. This solution, however, utilizes a double-hinged structure design, ensuring power transmission efficiency while allowing each connection point to adaptively adjust its relative position. This reduces frictional losses between moving parts and improves the system's compatibility with different installation conditions.

[0052] Through the above technical solution, this application achieves high-efficiency operation and low-loss characteristics of the power transmission mechanism (link assembly 300) of the heat dissipation device 400. The articulated link assembly 300 can effectively absorb positional deviations during movement and avoid energy loss caused by mechanical interference. This not only reduces the noise level of traditional heat dissipation systems during operation, but also improves energy conversion efficiency by reducing unnecessary friction, thereby fundamentally solving the problem of high power consumption of robot joint heat dissipation modules.

[0053] Furthermore, in one embodiment, as Figure 1As shown, the linkage assembly 300 also includes a second linkage 320. There are multiple heat dissipation devices 400 arranged in a straight line. The second linkage 320 sequentially connects the piston portions 410 of the multiple heat dissipation devices 400 to drive the multiple piston portions 410 to move synchronously. The second linkage 320 is a rigid rod-like structure, which can be made of metal or high-strength composite materials. Its function is to connect the piston portions 410 of the multiple heat dissipation devices 400 in series to form a linkage structure. The multiple heat dissipation devices 400 arranged in a straight line means that the multiple heat dissipation devices 400 are distributed at equal intervals along a straight line. This can be achieved using a fixed bracket or a slide rail structure, and its function is to form a compact heat dissipation array. The second connecting rod 320 is connected to multiple piston parts 410 in sequence. This means that the second connecting rod 320 is physically connected to each piston part 410 through branch rod 322 or connecting block. Specifically, it can be achieved by welding, riveting or hinge. Its function is to evenly transmit the driving force of a single spring pressure member 200 to all piston parts 410.

[0054] One end of the first link 310 is hinged to the movable end of the spring-loaded member 200, and the other end is hinged to one end of the second link 320. That is to say, in this embodiment, a single action of the spring-loaded member 200 can achieve the synchronous action of multiple heat dissipation devices 400 through the cooperation of the first link 310 and the second link 320, which is beneficial for the synchronous heat dissipation of multiple power components 800 distributed throughout the robot.

[0055] Specifically, when the movable end of the spring-loaded component 200 is subjected to external pressure, the first connecting rod 310 is pushed and drives the second connecting rod 320 to move in a straight line. At this time, the branch rod 322 of the second connecting rod 320 transmits the driving force to the piston portion 410 of each heat dissipation device 400, causing multiple piston portions 410 to move synchronously in either the first or second direction. When the external pressure disappears, the elastic restoring force of the spring-loaded component 200 pulls the second connecting rod 320 in the opposite direction through the first connecting rod 310, causing multiple piston portions 410 to move synchronously in either the second or first direction. Through the series structure of the second connecting rods 320, the movement of a single spring-loaded component 200 can synchronously drive multiple heat dissipation devices 400 to work, and the liquid working fluids of multiple heat dissipation devices 400 can undergo phase change simultaneously, thereby significantly improving the overall heat dissipation efficiency.

[0056] Furthermore, in one embodiment, such as Figure 2As shown, the second connecting rod 320 includes a main rod body 321 and multiple branch rod bodies 322. The main rod body 321 is a rigid rod-shaped structure used to transmit power, which can be made of metal or high-strength composite materials and can withstand the tensile or compressive forces transmitted by the connecting rod assembly 300. The branch rod bodies 322 are rod-shaped structures that are fixedly connected to the main rod body 321 and extend outward. They can be connected to the main rod body 321 by welding, riveting, or integral molding. One end of the main rod body 321 is hinged to the first connecting rod 310. Each branch rod body 322 has one end fixedly connected to the main rod body 321 and the other end connected to the piston part 410 of the corresponding heat dissipation device 400. That is, the branch rod bodies 322 are used to synchronously transmit the power of the main rod body 321 to multiple piston parts 410. The piston part 410 refers to a sealing component that can move along the inner wall of the housing 420. Specifically, it can adopt a piston head structure with a sealing ring. By moving, the volume of the inner cavity of the housing 420 is changed to drive the phase change of the liquid working fluid.

[0057] At this time, the main rod 321 can synchronously drive multiple branch rods 322 to move. For example, there are four branch rods 322, two of which extend towards the footrest 100, and the other two extend towards the robot's head. When the main rod 321 moves upward, all four branch rods 322 move towards the robot's head.

[0058] Specifically, when the movable end of the spring-loaded component 200 is subjected to external pressure, the first connecting rod 310 transmits the deformation displacement of the spring-loaded component 200 to the main rod 321. The main rod 321, through multiple branch rods 322, simultaneously drives the piston portions 410 of multiple heat dissipation devices 400 to move in the same direction. Since the branch rods 322 are fixedly connected to the main rod 321, the movement strokes of the multiple piston portions 410 remain synchronized, avoiding reduced heat dissipation efficiency or structural interference caused by asynchronous movements. The connection between the branch rods 322 and the piston portions 410 can be achieved by hinge or sliding fit, for example, by providing a ball joint at the outer end of the piston portion 410 to achieve multi-degree-of-freedom motion compensation.

[0059] Compared with existing technologies, traditional heat dissipation devices 400 typically employ independent drive structures or complex gear transmission mechanisms to synchronize multiple piston sections 410, resulting in complex structures and high energy consumption. This solution, through a rigid connection structure between the main rod 321 and the branch rod 322, achieves synchronized operation of multiple piston sections 410 without an additional power source, simplifying the mechanical structure while reducing energy loss.

[0060] Specifically, in one embodiment, such as Figure 3As shown, the heat dissipation device 400 also includes a first one-way valve 500 and a second one-way valve 600. The first one-way valve 500 is disposed inside the housing 420 to divide the interior of the housing 420 into a cooling chamber 421 and a movable chamber 422. It should be noted that the first one-way valve 500 can control the unidirectional flow of fluid within the housing 420. In this embodiment, the working fluid can only flow unidirectionally from the cooling chamber 421 to the movable chamber 422. Therefore, the cooling chamber 421 and the movable chamber 422 are in a unidirectional connected state under specific conditions and in an isolated state under other conditions.

[0061] The cooling chamber 421 refers to the space that houses the power element 800 and provides storage for the liquid working fluid. Specifically, it can be formed into a sealed chamber by a corrosion-resistant metal shell 420. The power element 800 is disposed within the cooling chamber 421, and the liquid working fluid is at least partially immersed in the heating end of the power element 800, or the liquid working fluid is sprayed onto the surface of the heating end of the power element 800 through a nozzle 700. In other words, the liquid working fluid is disposed within the cooling chamber 421 to ensure that the heating end of the power element 800 is in direct contact with the liquid working fluid so that the heating end of the power element 800 can dissipate heat in a timely manner. Alternatively, a liquid-absorbing core (similar to a sponge structure) filled with liquid working fluid can be provided at the heating end of the power element 800, in which case the heating end of the power element 800 can also be considered to be directly immersed in the liquid working fluid.

[0062] The movable chamber 422 refers to the mechanical structure that accommodates the movement of the piston part 410 and forms the vaporization chamber 423 and the mating chamber 424. Specifically, the reciprocating motion of the piston part 410 can be achieved through a cavity structure with guide grooves. The piston part 410 is movably disposed in the movable chamber 422 and divides the movable chamber 422 into the non-connected vaporization chamber 423 and the mating chamber 424. Furthermore, the cooling chamber 421 can be unidirectionally connected to the vaporization chamber 423 through the first one-way valve 500. The first one-way valve 500 is a fluid control device that only allows the liquid working fluid in the cooling chamber 421 to flow unidirectionally into the vaporization chamber 423. Specifically, it can be implemented using a spring-loaded ball check valve, which achieves unidirectional flow under the action of pressure difference. Obviously, when the position of the first one-way valve 500 remains unchanged, the total volume of the movable chamber 422 remains unchanged. Therefore, the sum of the volumes of the vaporization chamber 423 and the mating chamber 424 remains unchanged. That is, the vaporization chamber 423 and the mating chamber 424 are in a trade-off relationship. When the piston part 410 moves away from the first one-way valve 500, the volume of the vaporization chamber 423 increases and the volume of the mating chamber 424 decreases. Conversely, when the piston part 410 moves closer to the first one-way valve 500, the volume of the vaporization chamber 423 decreases and the volume of the mating chamber 424 increases.

[0063] The vaporization chamber 423 of the housing 420 can be unidirectionally connected to the atmospheric environment through the second one-way valve 600. The second one-way valve 600 is a pressure relief device that only allows the gaseous working fluid of the vaporization chamber 423 to be discharged into the external environment in one direction. Specifically, it can be implemented using a diaphragm-type one-way valve, which automatically opens and closes based on the pressure difference. It should be noted that the two are in a constant connection relationship. Regardless of the change in the volume of the vaporization chamber 423, the second one-way valve 600 can only connect to the vaporization chamber 423 and will not connect to the mating chamber 424.

[0064] When the spring-loaded component 200 drives the piston part 410 to move away from the first one-way valve 500 via the connecting rod assembly 300, the vaporization chamber 423 expands and the second one-way valve 600 closes. The liquid working medium in the cooling chamber 421 can enter the vaporization chamber 423 through the first one-way valve 500 and undergo phase change vaporization into a gaseous working medium. It should be noted that due to the expansion of the vaporization chamber 423, the gas pressure inside the vaporization chamber 423 decreases. Since the cooling chamber 421 can be unidirectionally connected to the vaporization chamber 423 through the first one-way valve 500, the liquid working fluid in the cooling chamber 421 enters the vaporization chamber 423 under the action of pressure difference. Because the gas pressure after the expansion of the vaporization chamber 423 is significantly lower than atmospheric pressure, the boiling point of the working fluid in the vaporization chamber 423 decreases. When the gas pressure in the vaporization chamber 423 drops to the threshold, both the liquid working fluid entering the vaporization chamber 423 and the liquid working fluid in the cooling chamber 421 will undergo a phase change. The phase change requires heat absorption, so a large amount of heat will be carried away during this process, thereby removing the heat generated by the power element 800.

[0065] When the spring-loaded component 200 drives the piston 410 to move towards the first one-way valve 500 via the connecting rod assembly 300, the vaporization chamber 423 is compressed, and the first one-way valve 500 closes, allowing the gaseous working fluid in the vaporization chamber 423 to enter the atmosphere through the second one-way valve 600. It should be noted that because the second one-way valve 600 opens, the gaseous working fluid in the vaporization chamber 423 is rapidly discharged from the vaporization chamber 423.

[0066] Of course, in order to meet environmental protection requirements, the working fluid used is a harmless coolant such as water or ethanol.

[0067] Specifically, taking the example of the piston section 410 moving in the first direction, where the liquid working fluid undergoes a phase change and absorbs heat, and the piston section 410 moving in the second direction, where the piston section 410 discharges the gaseous working fluid, as an example: When external pressure drives the spring-loaded component 200 to deform, the connecting rod assembly 300 moves the piston section 410 away from the cooling chamber 421. At this time, the volume of the vaporization chamber 423 increases, forming a negative pressure. The liquid working fluid in the cooling chamber 421 is drawn into the vaporization chamber 423 and undergoes a phase change, absorbing heat from the power element 800. When the pressure is released, the spring-loaded component 200 resets, pushing the piston section 410 back to compress the vaporization chamber 423. The gaseous working fluid is discharged through the second one-way valve 600 under pressure, completing the heat dissipation cycle.

[0068] Conversely, taking the example of the piston section 410 moving in the second direction, where the liquid working fluid undergoes a phase change and absorbs heat, and the piston section 410 moving in the first direction, where it discharges the gaseous working fluid: When the external pressure is released, the connecting rod assembly 300 drives the piston section 410 away from the cooling chamber 421. At this time, the volume of the vaporization chamber 423 increases, forming a negative pressure. The liquid working fluid in the cooling chamber 421 is drawn into the vaporization chamber 423 and undergoes a phase change, absorbing heat from the power element 800. When the external pressure presses the spring member 200, the spring member 200 resets and pushes the piston section 410 back to compress the vaporization chamber 423. The gaseous working fluid is discharged through the second one-way valve 600 under pressure, completing the heat dissipation cycle.

[0069] During this process, the one-way valve assembly (including the first one-way valve 500 and the second one-way valve 600) automatically controls the flow direction of the working fluid without the need for an additional power source.

[0070] Compared to existing technologies, traditional cooling systems rely on electric pumps to drive coolant circulation, while this solution achieves working fluid phase change circulation through mechanical linkage, avoiding continuous power consumption by the motor or pump. Existing technologies generate mechanical vibration noise during cooling module operation, while this solution significantly reduces operating noise by utilizing energy storage in elastic components and passive control via one-way valves.

[0071] Through the above technical solution, this application achieves passive phase change heat dissipation for the power element 800. The working fluid circulation is driven by mechanical linkage, enabling heat absorption and dissipation without external power supply. A one-way valve group precisely controls the working fluid flow path, preventing backflow of the liquid working fluid that could lead to heat dissipation failure. The physical isolation design between the vaporization chamber 423 and the cooling chamber 421 ensures the stability of the phase change process and prevents working fluid leakage from contaminating other electronic components within the robot.

[0072] To further improve heat dissipation efficiency, in one embodiment, there are two housings 420. The piston part 410, the first one-way valve 500, the second one-way valve 600, and the housing 420 are arranged in a one-to-one correspondence. The two housings 420 share a cooling chamber 421. One or more power components 800 are arranged in the cooling chamber 421, and the cooling chamber 421 can be connected to the corresponding vaporization chamber 423 through the corresponding first one-way valve 500. That is, with the cooling chamber 421 as the center, the two housings 420 are arranged opposite each other in two directions.

[0073] Furthermore, the linkage assembly 300 can drive the two piston sections 410 to move synchronously in the same direction. At this time, when the vaporization chamber 423 of the first housing 420 expands, the vaporization chamber 423 of the second housing 420 is compressed. It should be noted that due to the presence of the first one-way valve 500, the vaporization chamber 423 of the second housing 420 and the cooling chamber 421 are not connected. Therefore, it will not affect the expansion of the first vaporization chamber 423 to vaporize the liquid working fluid in the cooling chamber 421. Thus, this arrangement allows the two vaporization chambers 423 of the two housings 420 to expand alternately, thereby ensuring that the cooling chamber 421 where the power element 800 is located is in a continuous vaporization and heat dissipation state, thus ensuring continuous heat dissipation of the power element 800. This application also provides a robot that includes the energy-saving heat dissipation mechanism described in any of the above embodiments.
