[0055] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0056] Please refer to Figures 1 to 13 , Embodiment 1 of the present invention provides a heat dissipation device, including a heat dissipation housing 10, a blower fan 20 and a plugging member 30. The heat dissipation housing 10 has an air inlet 11, an air outlet 12 and an installation cavity 13, and both the air inlet 11 and the air outlet 12 are communicated with the installation cavity 13. The blower fan 20 is rotatably arranged in the installation cavity 13, and the blower fan 20 has a starting state and a stopping state. At least part of the plugging member 30 is movably arranged in the installation cavity 13; when the blower fan 20 is in the starting state, the plugging member 30 moves to an avoidance position spaced from the air inlet 11, so that the air inlet 11 is communicated with the heat dissipation space of the component to be cooled; when the blower fan 20 is in the stopping state, the plugging member 30 moves to a plugging position for plugging the air inlet 11, so that the air inlet 11 is disconnected from the air outlet 12.

[0057] With such a setting method, the plugging member 30 is selected to be in the corresponding working position according to whether the blower fan 20 starts or not, so that a heat dissipation channel can be formed when the heat dissipation device needs to dissipate heat, and a sealed space can be formed when the heat dissipation device needs to be sealed, thereby being able to solve the technical problem that the heat dissipation device of the collaborative robot joint module in the prior art cannot simultaneously meet heat dissipation and sealing.

[0058] In this embodiment, the heat dissipation device further includes a driving member 40. The driving member 40 is installed in the installation cavity 13, and the driving member 40 is used to drive the blocking member 30 to move to the avoidance position or the blocking position. When the blocking member 30 needs to move to the blocking position, the driving member 40 will release it and block the gap between the blocking member 30 and the heat dissipation housing 10; when the blocking member 30 needs to move to the avoidance position, the driving member 40 will pull back the blocking member 30 to form a gap between it and the heat dissipation housing 10. The driving member 40 can meet the movement requirements of the blocking member 30, so as to meet the heat dissipation and sealing requirements of the heat dissipation device according to the working conditions.

[0059] Specifically, the driving member 40 is fixedly installed in the installation cavity 13, and the driving member 40 is arranged on the side of the blocking member 30. Among them, the driving member 40 is an electromagnetic member, and the blocking member 30 is made of iron or magnetic material. When the driving member 40 is energized, the blocking member 30 moves to the avoidance position or the blocking position under the action of the magnetic force between the driving member 40 and the blocking member 30. Or it can also be that the blocking member 30 is an electromagnetic member and the driving member 40 is made of iron or magnetic material; when the blocking member 30 is energized, the blocking member 30 moves to the avoidance position or the blocking position under the action of the magnetic force between the driving member 40 and the blocking member 30. By adopting the cooperation mode of the electromagnetic member and iron or magnetic material, the presence or absence of the magnetic attraction force is controlled by energization and de-energization. This method is simple, easy to control, efficient and reliable. At the same time, this method can also shorten the response time between mechanisms, and can meet the requirements of the heat dissipation device for different working conditions faster, thereby improving the working efficiency of the heat dissipation device.

[0060] In this embodiment, the heat dissipation device further includes an elastic reset member 50, and the elastic reset member 50 is connected to the blocking member 30. The elastic reset member 50 and the driving member 40 are respectively arranged on both sides of the blocking member 30. The driving member 40 is used to drive the blocking member 30 to move to the avoidance position, and the elastic reset member 50 is used to reset the blocking member 30 to the blocking position. By setting the elastic reset member 50, when the blocking member 30 needs to be reset to the blocking position, it can be directly pulled back, so there is no need to set other transmission mechanisms. And when the heat dissipation device does not need heat dissipation, the elastic reset member 50 will always tighten the blocking member 30, which can meet the sealing requirements of the heat dissipation device, improve the sealing performance of the heat dissipation device, and prevent too many impurities from entering the heat dissipation device when heat dissipation is not required.

[0061] Specifically, the elastic reset member 50 in this embodiment can be a disc spring.

[0062] Specifically, the blocking member 30 is movably arranged. The blocking member 30 includes a blocking plate 31 and a guide rod 32 which are connected to each other. A guide hole 14 adapted to the outer shape of the guide rod 32 is provided on the heat dissipation housing 10. The guide hole 14 is spaced from the air inlet 11. The guide rod 32 is movably inserted into the guide hole 14. The blocking plate 31 is movably arranged in the installation cavity 13. The blocking plate 31 is used to block or avoid the air inlet 11. When heat dissipation is not required, the blocking plate 31 can abut against the heat dissipation housing 10, thereby sealing the heat dissipation device. The structure of the blocking plate 31 can increase the blocking area and better ensure the sealing performance. Specifically, the blocking plate 31 can be in the structure of a circular plate.

[0063] In this embodiment, there are multiple air inlets 11, and the multiple air inlets 11 are arranged around the periphery of the guide hole 14. Such an arrangement can increase the heat exchange amount as much as possible, increase the gas flow rate in the heat dissipation device, and thus improve the heat dissipation efficiency of the heat dissipation device.

[0064] In this embodiment, the heat dissipation housing 10 includes a first housing 15. A first installation groove 151, an air inlet 11 and a guide hole 14 are provided on the first housing 15. The air inlet 11 and the guide hole 14 both penetrate through both sides of the first housing 15. The air inlet 11 and the guide hole 14 are both communicated with the first installation groove 151. The blocking plate 31 is movably installed in the first installation groove 151, and the edge of the blocking plate 31 is spaced from the groove edge of the first installation groove 151. With such an arrangement, when the blocking plate 31 is in the avoiding position, it is convenient for the heat dissipation air flow to flow out of the heat dissipation device through the gap between the blocking plate 31 and the first installation groove 151, so that the heat dissipation device can improve the smoothness of air flow as much as possible without affecting the airtightness.

[0065] Specifically, a gas guiding groove 311 is provided on the side of the blocking plate 31 away from the guide rod 32. The gas guiding groove 311 extends from the edge of the blocking plate 31 towards the middle of the blocking plate 31, and one end of the gas guiding groove 311 is arranged at the edge of the blocking plate 31. The setting of the gas guiding groove 311 can form a certain guiding effect, and can more conveniently dissipate the heat dissipation gas from the blocking plate 31.

[0066] In this embodiment, the heat dissipation housing 10 further includes a first housing 15 and a second housing 16. The first housing 15 has a first installation groove 151, and at least part of the blocking member 30 is installed in the first installation groove 151. The second housing 16 is provided with a communication channel 163, and the communication channel 163 is communicated with the first installation groove 151 to enclose an installation cavity 13, and the fan blade 20 is installed at the communication channel 163. With such an arrangement, it is more convenient to install the fan blade 20 and can reduce the installation difficulty.

[0067] Specifically, a fifth installation groove is further provided on the first housing 15. The fifth installation groove is disposed around the periphery of the guiding hole 14 and is in communication with the guiding hole 14. The fifth installation groove is located on the side of the first housing 15 away from the installation cavity 13. The elastic reset member 50 is installed in the fifth installation groove, and the elastic reset member pressing plate 51 is installed at the notch of the fifth installation groove. The elastic reset member pressing plate 51 presses on the elastic reset member 50.

[0068] In this embodiment, a second installation groove 161 and a third installation groove 162 are provided on the second housing 16. The second installation groove 161 and the third installation groove 162 are respectively located on both sides of the communication channel 163. The third installation groove 162 is provided on the side of the second installation groove 161 close to the plugging member 30. Among them, the shape of the second installation groove 161 is adapted to the shape of the installation portion of the wind blade 20, and the wind blade 20 is installed at the second installation groove 161. The shape of the third installation groove 162 is adapted to the shape of the driving member 40, and the driving member 40 is installed at the third installation groove 162. Alternatively, the heat dissipation housing 10 further includes a third sealing member 17, and the third sealing member 17 is provided between the first housing 15 and the second housing 16. With the arrangement of the third sealing member 17, further sealing can be formed at the original mating gap, thereby better improving the sealing performance of the heat dissipation device and preventing water vapor and dust from entering the heat dissipation device.

[0069] In this embodiment, the side of the heat dissipation housing 10 close to the air inlet 11 has a connection portion for connecting with the component to be cooled. A first sealing member 18 is provided at the connection portion, or alternatively, a second sealing member 19 is provided on the inner wall of the installation cavity 13, and the second sealing member 19 is located between at least a part of the plugging member 30 and the inner wall of the installation cavity 13. The arrangement of the sealing member can further enhance the sealing performance.

[0070] Alternatively, the heat dissipation device may further include a protective cover 60. The protective cover 60 is installed on the heat dissipation housing 10, and the protective cover 60 covers the air outlet 12. The air outlet grille on the protective cover 60 is disposed opposite to the air outlet 12. By providing the protective cover 60, a first layer of protection can be formed at the air outlet 12, and most large-particle dust and some small-particle dust can be pre-filtered, thereby further enhancing the airtightness of the heat dissipation device and improving its dust resistance. Moreover, the arrangement of the protective cover 60 can also provide a certain degree of protection for the internal devices, preventing the internal devices from being directly exposed and damaged.

[0071] In this embodiment, the heat dissipation device mainly consists of a first housing 15, a second housing 16, a protective cover 60, an elastic resetting piece pressing plate 51, an elastic resetting piece 50 (which can be a pressing plate spring), a sliding bearing 70, a plugging piece 30, a driving piece 40, a fan blade 20, and a dust-proof net 80. A fourth installation groove 152 is provided on one end face of the first housing 15, which can be embedded into the end of the joint module and is connected and fixed to the joint module by screws. A first sealing ring groove is provided around the fourth installation groove 152 for installing a first sealing member 18 to ensure a tight connection between the first housing 15 and the joint module and prevent external water vapor and dust from penetrating into the joint module.

[0072] Specifically, a spring installation groove is provided at the center of the fourth installation groove 152 for installing the elastic resetting piece 50. A guiding hole 14 is provided at the center of the spring installation groove, and the guiding hole 14 communicates with a sliding bearing groove provided at the center of the other end face of the fourth installation groove 152. A number of air inlets 11 are provided around the spring installation groove. The air inlets 11 communicate with a first installation groove 151 provided on the other end face of the fourth installation groove 152. A second sealing ring groove is provided on the first installation groove 151 for installing a second sealing member 19. A third sealing ring groove is provided on the other end face of the first housing 15 for installing a third sealing member 17 to ensure a tight connection between the first housing 15 and the second housing 16 and prevent external dust from penetrating into the first housing 15. The second housing 16 is connected and fixed to the first housing 15 by screws.

[0073] In this embodiment, the plugging piece 30 consists of a guiding rod 32 and a plugging plate 31, and a number of air guiding grooves 311 are provided on the plugging plate 31. The plugging piece 30 is installed in the first installation groove 151 of the first housing 15. The guiding rod 32 sequentially passes through the sliding bearing 70 installed in the sliding bearing groove, the elastic resetting piece 50 installed in the spring installation groove to the spring installation groove, and is connected by screws to the elastic resetting piece pressing plate 51. The end face of the elastic resetting piece pressing plate 51 is in close contact with the elastic resetting piece 50.

[0074] Specifically, a third installation groove 162 is provided on one end face of the second housing 16 for installing the driving piece 40. A communication channel 163 is provided at the center of the third installation groove 162, and the communication channel 163 communicates with a fan groove provided on the other end face of the second housing 16. The driving piece 40 is connected and fixed to the second housing 16 by screws. The fan blade 20 is installed in the fan groove and is connected and fixed to the second housing 16 by screws. One end face of the fan blade 20 is in contact with the bottom of the fan groove, and the other end face is in contact with the dust-proof net 80. The dust-proof net 80 is connected and fixed to the fan blade 20 by screws.

[0075] In this embodiment, the protective cover 60 is connected and fixed to the second housing 16 by screws. An exhaust groove 61 is provided at the center of the protective cover 60, and the position of the exhaust groove 61 is directly opposite to the fan blade 20, which is convenient for the fan blade 20 to discharge the air flow.

[0076] Specifically, the heat dissipation device has two operating states: start and stop. When the joint module is running, the heat dissipation device starts, the fan blade 20 is powered on and rotates, the driving member 40 is powered on to generate magnetism, attracting the plugging member 30 to move towards the driving member 40 until the plugging member 30 fits with the driving member 40. At the same time, the guide rod 32 on the plugging member 30 drives the elastic reset member pressing plate 51 under the guidance of the sliding bearing 70 to compress the elastic reset member 50. At this time, the hot air inside the joint module, under the action of the fan blade 20, enters the inside of the first installation groove 151 through the air inlet 11 on the first housing 15, and successively passes through the gap between the plugging member 30 and the first installation groove 151, the air guide groove 311 on the plugging member 30, passes through to the communication channel 163 at the center of the second housing 16 and is sucked by the fan blade 20, and is discharged through the exhaust groove 61 in the center of the protective cover 60. The fan blade 20 only operates at the right time according to the working state of the joint module, and is not affected by the movement direction of the joint module, which can ensure that the heat dissipation device is always in the air extraction state, reducing the heat accumulation generated when the joint module is running.

[0077] When the joint module is not working, the heat dissipation device starts to stop, the fan blade 20 stops running, the driving member 40 is powered off and does not generate magnetism, the elastic reset member 50 resets, and drives the plugging member 30 to move in the reverse direction (away from the driving member 40) under the guidance of the sliding bearing 70 through the elastic reset member pressing plate 51 until it fits and compresses with the second seal 19 installed in the second seal groove, preventing the moisture outside the module from seeping into the module when the fan blade 20 stops running. The dust-proof net 80 installed on the fan blade 20 can effectively block the dust outside the module and prevent it from entering the inside of the heat dissipation device when the fan blade 20 stops running.

[0078] In this embodiment, to improve the waterproof performance of the heat dissipation device, desiccants can also be filled in the gap space between the fan blade 20 and the protective cover 60 to absorb excess moisture.

[0079] Specifically, a number of ventilation holes can also be provided on the first housing 15 to allow the hot air inside the joint module to flow into the inside of the first installation groove 151. The ventilation holes can also be changed to ventilation grooves according to the air flow passing through to increase the cross-sectional area of the air passing through.

[0080] Embodiment 2 of the present invention provides a joint module, including joint components and the heat dissipation device provided in Embodiment 1. The heat dissipation device is connected to the joint components, and the air inlet 11 of the heat dissipation device is communicated with the heat dissipation space of the joint components. Specifically, the joint module in this embodiment belongs to a part of a robot.

[0081] Specifically, the joint component has a working state and a non-working state. The joint module further includes a control member, and both the joint component and the heat dissipation device are connected to the control member. When the joint component is in the working state, the control member controls the fan 20 of the heat dissipation device to be in the starting state; when the joint component is in the non-working state, the control member controls the fan 20 of the heat dissipation device to be in the stopping state.

[0082] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: By providing the blocking member 30, the blocking member 30 can adjust its own opening and closing in a timely manner according to different working states of the fan 20, so that it has two working positions, namely an avoidance position and a blocking position. When the heat dissipation device needs to dissipate heat, a heat dissipation channel is formed, and when the heat dissipation device needs to be airtight, a sealed space can be formed, thereby being able to solve the technical problem that the heat dissipation device of the collaborative robot joint module in the prior art cannot simultaneously meet heat dissipation and sealing.

Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0086] For convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "above-mentioned", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used here will be made.

[0087] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present application.
