[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figures 1 to 5, which is the first embodiment of the utility model, and this embodiment provides a servo motor that is easy to dissipate heat. The servo motor that is easy to dissipate heat includes a main body component 100 and a heat dissipation component 200. The heat dissipation effect of the main body component 100 can be improved by the heat dissipation component 200.

[0029] Specifically, the main body assembly 100 includes a motor housing 101 and a rotating shaft 102 , and the rotating shaft 102 is located at one side of the motor housing 101 .

[0030] There are multiple motor housings 101, and electronic components such as a rotor, an encoder, and a controller (not shown) are arranged in the motor housing 101. One end of the rotating shaft 102 passes through the motor housing 101, and the other end is located outside the motor housing 101. This is the prior art, and the present invention will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0031] Specifically, the heat dissipation assembly 200 is arranged on the motor housing 101, and includes a breathable member 201, a rotating member 202, a movable member 203, an extrusion member 204 and a fixed member 205. The breathable member 201 is arranged in the motor housing 101, the rotating member 202 is located on one side of the motor housing 101, the movable member 203 is arranged on one side of the motor housing 101, the extrusion member 204 is located on one side of the movable member 203, and the fixed member 205 is arranged on one side of the motor housing 101.

[0032] By setting the air-permeable member 201, when the temperature inside the motor housing 101 is low, the air-permeable member 201 is in a closed state, and the inside of the motor housing 101 can be blocked, thereby preventing dust from entering the motor housing 101 during use. When the temperature inside the motor housing 101 rises, the air-permeable member 201 will open, so that the air inside the motor housing 101 can circulate with the outside, so that the heat inside the motor housing 101 can be discharged to the outside in time, thereby improving the heat dissipation effect of the motor, and in the heat dissipation process, since the heat inside the motor housing 101 is discharged to the outside, the discharged heat can also push the dust outside, thereby preventing dust from entering the motor housing 101 during the heat dissipation process.

[0033] When the temperature inside the motor housing 101 is too high, the extrusion part 204 will expand due to the high temperature and push the moving part 203 to move. When the moving part 203 moves, it will drive the rotating part 202 to rotate, and the rotating part 202 will drive the breathable part 201 to open, so that the heat inside the motor housing 101 can be discharged in time. The setting of the fixed part 205 is used to limit the rotating part 202, so as to prevent the rotating part 202 from shifting in position while rotating.

[0034] Example 2

[0035] Reference Figures 2 to 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the air-permeable member 201 includes a heat dissipation plate 201a and a fixed shaft 201b. A heat dissipation hole 101-1 is provided on the motor housing 101. The heat dissipation plate 201a is engaged with the heat dissipation hole 101-1, and the fixed shaft 201b is fixed in the heat dissipation plate 201a.

[0037] There are multiple heat sinks 201a and heat dissipation holes 101-1, and the number of heat sinks 201a and heat dissipation holes 101-1 on multiple motor housings 101 is equal and arranged linearly. Through the setting of the heat sink 201a, the opening and closing of the heat dissipation holes 101-1 on the motor housing 101 can be effectively controlled. When the heat sink 201a is separated from the heat dissipation holes 101-1, the heat generated in the motor housing 101 can be effectively discharged. When the heat sink 201a is engaged with the heat dissipation holes 101-1, the external dust can be effectively prevented from entering the motor housing 101. Then, the fixed shaft 201b is set to fix the heat sink 201a. When the fixed shaft 201b rotates, it will cause the heat sink 201a to rotate, and then drive the heat sink 201a and the heat dissipation holes 101-1 to separate and engage.

[0038] Specifically, the rotating member 202 includes a fixed plate 202a, a movable plate 202b and a first fixed column 202c. The fixed plate 202a is fixed on the fixed shaft 201b. The movable plate 202b is arranged on one side of the fixed plate 202a. The movable plate 202b is provided with a clamping hole 202b-1, and the first fixed column 202c is engaged with the clamping hole 202b-1.

[0039] There are multiple fixed plates 202a, which are fixed to different fixed shafts 201b respectively. There are also multiple first fixed columns 202c, which are fixed to different fixed plates 202a respectively. There are multiple clamping holes 202b-1 on the movable plate 202b. When the first fixed column 202c is engaged with the clamping hole 202b-1, when the movable plate 202b moves, it will drive the first fixed column 202c to move, and then drive the fixed plate 202a to rotate, and then drive the fixed shaft 201b to rotate, which will further drive the heat sink 201a and the heat dissipation hole 101-1 to separate and engage.

[0040] Specifically, the rotating member 202 also includes a rotating plate 202d, a second fixed column 202e and a rotating column 202f. The rotating plate 202d is arranged on one side of the movable plate 202b. One end of the second fixed column 202e is fixed to the fixed plate 202a. The rotating plate 202d is provided with a slot 202d-1. The second fixed column 202e slides in the slot 202d-1. The rotating column 202f is located on one side of the rotating plate 202d.

[0041] There are multiple rotating plates 202d, one end of which is fixed to the rotating column 202f. The rotating column 202f is rotatably connected to the motor housing 101 through a bearing. When the rotating column 202f rotates, it will drive the rotating plate 202d to rotate. When the rotating plate 202d rotates, it will push the second fixed column 202e to move through the inner wall of the slot 202d-1, so that the second fixed column 202e can drive the movable plate 202b to move.

[0042] Specifically, the moving member 203 includes a moving block 203a and a third fixed column 203b. The moving block 203a is arranged in the rotating column 202f. The third fixed column 203b is fixed to one side of the moving block 203a. A spiral groove 202f-1 is opened on the rotating column 202f, and the third fixed column 203b slides in the spiral groove 202f-1.

[0043] Through the setting of the moving block 203a, when the moving block 203a moves, it will drive the third fixed column 203b to slide in the spiral groove 202f-1, and then drive the rotating column 202f to rotate, and then drive the rotating plate 202d to rotate, and then drive the second fixed column 202e to slide in the slot 202d-1, and then drive the movable plate 202b to move, and then drive the first fixed column 202c to move, and then drive the fixed plate 202a to rotate, and then drive the fixed shaft 201b to rotate, thereby driving the heat dissipation plate 201a and the heat dissipation hole 101-1 to separate and engage.

[0044] Specifically, the moving member 203 further includes a limit block 203c, which is disposed on one side of the moving block 203a. The moving block 203a is provided with a limit slot 203a-1, and the limit block 203c is movably connected to the limit slot 203a-1.

[0045] The limit block 203c is rectangular. Through the setting of the limit block 203c, when the moving block 203a moves, the limit block 203c will slide in the limit groove 203a-1, so as to limit the movement of the moving block 203a, so that the moving block 203a can only perform translational movement, preventing the moving block 203a from performing rotational movement, resulting in the inability to rotate the rotating column 202f, and further resulting in the inability to control the opening and closing of the heat sink 201a.

[0046] Example 3

[0047] Reference Figures 4-5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, the extrusion member 204 includes an induction disc 204a and an expansion block 204b. The induction disc 204a is fixed in the motor housing 101, and the expansion block 204b is disposed in the induction disc 204a.

[0049] The induction disk 204a has a heat-conducting effect, and the expansion block 204b has the characteristics of thermal expansion and contraction, and can clearly sense temperature changes. When the heat inside the motor housing 101 rises sharply, the induction disk 204a will transfer the heat to the expansion block 204b. At this time, the expansion block 204b will expand, and then push the moving block 203a to move upward, thereby driving the third fixed column 203b to slide in the spiral groove 202f-1, and then driving the rotating column 202f to rotate. At the same time, the rotating plate 202d will also rotate, and then drive the second fixed column 202e to slide in the slot 202d-1, thereby driving the movable plate 202b to move, and then drive the first fixed column 202c to move, thereby driving the fixed plate 202a to rotate, and then drive the fixed shaft 201b to rotate, and at this time the heat sink 201a will open.

[0050] Specifically, the extruding member 204 further includes a first spring 204c, and the first spring 204c is fixed to one side of the moving block 203a.

[0051] When the moving block 203a moves upward, it will squeeze the first spring 204c. When the heat inside the motor housing 101 decreases, the expansion block 204b will shrink. At this time, the first spring 204c will give the moving block 203a a downward elastic force, so that the moving block 203a moves downward, and then drives the rotating column 202f to rotate in the opposite direction. At the same time, the rotating plate 202d will also rotate in the opposite direction, and then drive the second fixed column 202e to slide in the slot 202d-1, and then drive the movable plate 202b to move, and then drive the first fixed column 202c to move, and then drive the fixed plate 202a to rotate, and then drive the fixed shaft 201b to rotate, and then drive the heat sink 201a and the heat dissipation hole 101-1 to engage.

[0052] Specifically, the fixing member 205 includes a lower fixing plate 205a, a fourth fixing column 205b and an upper fixing plate 205c. The lower fixing plate 205a is fixed to one side of the motor housing 101, the fourth fixing column 205b is fixed on the lower fixing plate 205a, and the upper fixing plate 205c is fixed to one end of the fourth fixing column 205b.

[0053] The fourth fixing column 205b is provided to fix the lower fixing plate 205a and the upper fixing plate 205c, thereby preventing the rotating column 202f from translating, thereby preventing the second fixing column 202e and the slot 202d-1 from being separated, resulting in the inability to control the opening and closing of the heat sink 201a.

[0054] Specifically, the fixing member 205 further includes a fixing sleeve 205d, and the fixing sleeve 205d is fixed to one side of the upper fixing plate 205c.

[0055] The fixing sleeve 205d is provided to fix the limit block 203c and the first spring 204c. When the moving block 203a moves, the limit block 203c and the first spring 204c will also move relative to each other. At this time, the limit block 203c will limit the movement of the moving block 203a, so that the moving block 203a can only perform translational movement, and prevent the moving block 203a from performing rotational movement, resulting in the rotation column 202f being unable to perform rotational movement, thereby making it impossible to control the opening and closing of the heat sink 201a. At the same time, the first spring 204c will also move. When the heat sink 201a needs to be reset, the first spring 204c will give the moving block 203a a downward elastic force, thereby resetting the moving block 203a, thereby driving the heat sink 201a and the heat dissipation hole 101-1 to engage.

[0056] During use, when the motor works for a long time and the heat inside the motor housing 101 rises sharply, the induction disc 204a will transfer the heat to the expansion block 204b. At this time, the expansion block 204b will expand and then push the moving block 203a to move upward, thereby driving the third fixed column 203b to slide in the spiral groove 202f-1, and then driving the rotating column 202f to rotate. At the same time, the rotating plate 202d will also rotate, and then drive the second fixed column 202e to slide in the notch 202d-1, thereby driving the movable plate 202b to move, and then The first fixed column 202c is driven to move, and then the fixed plate 202a is driven to rotate, and then the fixed shaft 201b is driven to rotate. At this time, the heat dissipation plate 201a will be opened, so that the air inside the motor housing 101 can circulate with the outside, so that the heat inside the motor housing 101 can be discharged to the outside in time, thereby improving the heat dissipation effect of the motor, and in the heat dissipation process, since the heat inside the motor housing 101 is discharged to the outside, the discharged heat can also push the dust outside, thereby avoiding the situation where dust will enter the motor housing 101 during the heat dissipation process.

[0057] When the motor gradually stops working and the heat inside the motor housing 101 decreases, the expansion block 204b will shrink. At this time, the first spring 204c will give the moving block 203a a downward elastic force, so that the moving block 203a moves downward, and then drives the rotating column 202f to rotate in the opposite direction. At the same time, the rotating plate 202d will also rotate in the opposite direction, and then drive the second fixed column 202e to slide in the slot 202d-1, thereby driving the movable plate 202b to move, and then drive the first fixed column 202c to move, thereby driving the fixed plate 202a to rotate, and then drive the fixed shaft 201b to rotate, thereby driving the heat sink 201a and the heat dissipation hole 101-1 to engage, thereby effectively preventing external dust from entering the motor housing 101, thereby achieving more comprehensive protection for the inside of the motor housing 101.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
