Description

Technical Field

[0001] This application relates to the field of robot accessories, and more particularly to a servo motor mounting assembly. Background Technology

[0002] Currently, in fields such as unmanned aerial vehicles, toy robots, and automated machinery, there are high requirements for the precise positioning and stable control of servo motors. As one of the core actuators, the performance of the servo motor directly affects the operating efficiency and reliability of the entire system.

[0003] A servo motor typically consists of a servo motor body and a servo motor mounting plate. The mounting plate is used to connect and secure the servo motor to other servo motors. Typically, the mounting plate is U-shaped and fixed to the symmetrical sides of the servo motor body using bolts or screws. This results in only one fixed positional relationship between the mounting plate and the servo motor body. This is unsuitable when multiple positional relationships between the mounting plate and the servo motor body are required, especially for servo motor mounting plates used at the moving joints of a robot.

[0004] Therefore, there is an urgent need for a new servo mounting component to address the issue of establishing various positional relationships between the servo connecting plate and the servo body. Utility Model Content

[0005] To address the issue of various positional relationships between the traditional servo mounting plate and servo housing, this application provides a servo mounting assembly.

[0006] The servo mounting assembly provided in this application adopts the following technical solution:

[0007] A servo motor mounting assembly includes a mounting plate detachably connected to a servo motor body and a connecting plate detachably connected to the mounting plate. The mounting plate has a limiting hole and multiple connecting holes, which are threaded holes, evenly spaced along the circumference of the limiting hole. The connecting plate has clearance holes corresponding to the limiting hole, and multiple mounting holes are formed outside the clearance holes, evenly spaced along the circumference of the clearance holes. The number of mounting holes is greater than or equal to the number of connecting holes, and the center distance from the mounting hole to the limiting hole is the same as the center distance from the connecting hole to the limiting hole.

[0008] By adopting the above technical solution, when installing the connecting plate, the user first connects and fixes the mounting plate to the servo housing, then aligns the mounting holes on the connecting plate with the connecting holes, and the bolts are threaded through the mounting holes and connected to the connecting holes, thus connecting and fixing the connecting plate and the mounting plate. Since the mounting holes and connecting holes are circumferentially distributed, rotating the position of the connecting plate will always ensure that some of the mounting holes on the connecting plate align with the connecting holes. By fixing the connecting plate and the mounting plate with bolts, the connection position of the connecting plate and the mounting plate can be changed, thereby changing the connection position between the connecting plate and the servo housing. This solves the problem that there is only one positional relationship between the traditional servo connecting plate and the servo housing.

[0009] Optionally, the limiting hole is a first clearance hole, and the connecting hole is four first mounting holes, with a 90-degree angle between the center distance of two adjacent first connecting holes to the first clearance hole; the clearance hole on the connecting plate is a second clearance hole, with the second clearance hole having the same shape and size as the first clearance hole, and the mounting hole on the connecting plate is four second mounting holes, with a 90-degree angle between the center distance of two adjacent second mounting holes to the second clearance hole.

[0010] By adopting the above technical solution, when the user uses the device, the second mounting hole is used to mate with the first mounting hole on the mounting plate. The bolt passes through the second mounting hole and the first mounting hole, which can fix the positioning plate and the baffle. The positioning plate can rotate 90 degrees so that the four first mounting holes and the second mounting hole are always in abutting engagement, which can make the connecting plate perpendicular to the mounting plate. At the same time, the mounting plate can be rotated to coincide with the mounting plate or to the side opposite to the mounting plate. That is, the connecting plate can be connected to three sides of the servo housing, replacing the traditional servo connecting plate and servo housing with only one fixed position relationship.

[0011] Optionally, the clearance hole on the connecting plate may also include a plurality of auxiliary connecting holes, which are distributed circumferentially along the second clearance hole. The auxiliary mounting hole is located between two adjacent second mounting holes, and the center distance from the auxiliary mounting hole to the second clearance hole is equal to the center distance from the second mounting hole to the second clearance hole.

[0012] By adopting the above technical solution, when using the device, the auxiliary connecting hole can be rotated to coincide with one of the first mounting holes on the baffle. After the bolt passes through the auxiliary connecting hole, it is threaded to the first mounting hole, which allows the connecting plate to be installed on the mounting plate. This enables multiple positional relationships between the connecting plate and the servo housing, solving the problem that the traditional servo connecting plate and servo housing can only form one positional relationship.

[0013] Optionally, the limiting hole and the mounting hole are regular polygons.

[0014] By adopting the above technical solution, when the limiting hole and the mounting hole are regular polygons, the rotation angle of the connecting plate relative to the mounting plate can be limited, and the connecting plate and the mounting plate can be quickly aligned and fixed.

[0015] Optionally, the mounting plate has multiple sets of connection holes for connecting and fixing with other servos.

[0016] By adopting the above technical solution, when the output shaft of the servo is installed in different sets of connection holes, other servos can be installed in different positions on the mounting plate, thus changing the connection position of two adjacent servos to meet different needs.

[0017] Optionally, the mounting plate has a first connecting hole group and four second connecting hole groups at its center. The first connecting hole group includes a first insertion hole (circular), and four first connecting holes are arranged around the first insertion hole at equal intervals along its circumference. The distance from the center of each connecting hole to the center of the first insertion hole is equal, and the angle between the centers of two adjacent connecting holes is 90°. Each second connecting hole group includes a second insertion hole (circular). The second plug hole is located between two adjacent first connecting holes. The distance between the center of the second plug hole and the center of the first plug hole is greater than the distance between the centers of the first connecting holes. Each group of second connecting holes also includes two second connecting holes. The two second connecting holes and the two first connecting holes are evenly distributed around the second plug hole. The distance between the center of the first connecting hole and the center of the second plug hole is equal to the distance between the centers of the second connecting holes. The angle formed between the centers of two adjacent first connecting holes and the centers of the first plug hole is 90°.

[0018] By adopting the above technical solution, during user operation, both the first and second insertion holes are used to make way for the flange on the servo output shaft, facilitating flange insertion. The first connection hole allows other servos to be easily connected and fixed to the mounting plate, enabling the assembly of two servos. Similarly, the flange of the servo output shaft can be inserted into the second insertion hole, and the servo can be fixed through the two second connection holes and the two first connection holes. The servo output shaft can be fixed in either the first or second connection hole group as needed, allowing for more diverse connection positions between adjacent servos, replacing the traditional single connection position and meeting more connection requirements. Simultaneously, the mounting plates of two adjacent servos can be connected and fixed through the first connection hole, or through a combination of the first and second connection holes, achieving various positional relationships between the mounting plates on different servos.

[0019] Optionally, the mounting plate is provided with a clearance groove for the output shaft of the servo motor to pass through.

[0020] Optionally, the mounting plate has multiple positioning holes, which are either through holes or threaded holes. The servo housing has threaded holes, and the bolt passes through the positioning holes and is threadedly connected to the threaded holes on the servo housing.

[0021] By adopting the above technical solution, when the user uses the device, the bolt passes through the positioning hole and is threaded into the threaded hole on the servo housing, which can fix the mounting plate to the servo housing, making it easy to disassemble and install the mounting plate.

[0022] Optionally, a third mounting hole group is provided in the middle of the connecting plate. The third mounting hole group includes a third clearance hole and four third mounting holes. The third mounting holes are evenly distributed around the third clearance hole, and the distance from the center of the third mounting hole to the center of the third clearance hole is the same.

[0023] By adopting the above technical solution, the third mounting hole and the third clearance hole facilitate connection and fixation with the connecting plate on the adjacent servo. The connecting plate between two adjacent servos can be connected and fixed through the third mounting hole, realizing multiple positional relationships between the connecting plates on different servos. Moreover, the first connecting hole on the servo and the third clearance hole on other servos can be connected and fixed, thereby realizing multi-angle installation between adjacent servos.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By connecting a mounting plate to the servo housing, the mounting plate has a limiting hole and multiple connecting holes, which are threaded holes, and are evenly spaced along the circumference of the limiting hole. The connecting plate also has clearance holes corresponding to the limiting hole, and multiple mounting holes are located outside the clearance holes, with the mounting holes also evenly spaced along the circumference of the clearance holes. The number of mounting holes is greater than or equal to the number of connecting holes, and the center distance from the mounting hole to the limiting hole is the same as the center distance from the connecting hole to the limiting hole. Since both the mounting holes and connecting holes are circumferentially distributed, rotating the position of the connecting plate ensures that some of the mounting holes on the connecting plate always coincide with the connecting holes. By fixing the connecting plate and the mounting plate with bolts, the connection position of the connecting plate and the mounting plate can be changed, thereby changing the connection position between the connecting plate and the servo housing. This solves the problem that there is only one positional relationship between the traditional servo connecting plate and the servo housing. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a servo motor mounting assembly, referring to... Figure 1 It includes a mounting plate 2 connected to the servo housing 1 and a connecting plate 3 connected to the mounting plate 2.

[0034] Reference Figure 1 and Figure 2 The mounting plate 2 includes a fixed plate 21 and two baffles 22. The baffles 22 are perpendicular to the fixed plate 21 and symmetrically arranged on both sides. The baffles 22 are welded to the fixed plate 21 or integrally formed. The baffles 22 and the fixed plate 21 form a U-shape. The mounting plate 2 is used to install on the three outer sides of the servo housing 1. The two baffles 22 are symmetrically provided with relief grooves 23. The relief grooves 23 are arc-shaped and located near the ends of the baffles 22. The relief grooves 23 are used for the output shaft of the servo to pass through. The baffles 22 are provided with multiple positioning holes 24. Some positioning holes 24 are located at the three corners of the baffles 22, and the rest are located in the middle of the baffles 22. The positioning holes 24 are through holes or threaded holes 11. The four corners of the servo housing 1 are provided with threaded holes 11. After the bolt passes through the positioning holes 24, it is threadedly connected to the threaded holes 11 on the servo housing 1, which can fix the mounting plate 2 to the servo housing 1.

[0035] A first mounting hole group 25 is provided at the middle of the end of the baffle 22 away from the relief groove 23. The first mounting hole group 25 includes a first relief hole 251. The baffle 22 is provided with four first mounting holes 252 outside the first relief hole 251. The four first mounting holes 252 are distributed at equal intervals along the circumference of the first relief hole 251. The two adjacent first connecting holes 262 form a 90-degree angle with the center of the first relief hole 251. The distance between the center of the first mounting hole 252 and the center of the first relief hole 251 is equal. The first relief hole 251 is a regular polygon for easy installation and positioning. The figure shows that the first connecting hole 262 is a regular octagon, but it is not limited to a regular octagon. A regular polygon with four or more sides is acceptable. The first mounting hole 252 is a threaded hole.

[0036] Reference Figure 4 and Figure 5A first connecting hole group 26 is provided at the center of the fixing plate 21. The first connecting hole group 26 includes a first insertion hole 261, which is a round hole. The first insertion hole 261 is used to make way for the flange on the output shaft of the servo motor, so as to facilitate flange insertion. Four first connecting holes 262 are provided outside the first insertion hole 261. The four first connecting holes 262 are evenly distributed around the circumference of the first insertion hole 261. The distance from the center of the first connecting hole 262 to the center of the first insertion hole 261 is equal, and the angle formed between the center of two adjacent first connecting holes 262 and the center of the first insertion hole 261 is 90°. The first connecting holes 262 facilitate the connection and fixation of other servos to the mounting plate 2, so as to realize the connection and assembly of two servos. The fixed plate 21 is provided with four sets of second connecting hole groups 27. Each second connecting hole group 27 includes a second insertion hole 271. The second insertion hole 271 is a round hole and is used to make way for the flange on the servo output shaft. The second insertion hole 271 is located between two adjacent first connecting holes 262. The distance between the center of the second insertion hole 271 and the center of the first insertion hole 261 is greater than the distance between the centers of the first connecting holes 262 and the first insertion hole 261. Each second connecting hole group 27 also includes two second connecting holes 272. The two second connecting holes 272 and the two first connecting holes 262 are evenly distributed around the second insertion hole 271. The distance between the center of the first connecting hole 262 and the center of the second insertion hole 271 is equal to the distance between the centers of the second connecting holes 272 and the second insertion hole 271. The angle formed between the centers of two adjacent first connecting holes 262 and the centers of the first insertion hole 261 is 90°. The flange of the servo output shaft can be inserted into the second insertion hole 271, and then the servo is fixed through two second connection holes 272 and two first connection holes 262. The servo output shaft can be fixed in either the first connection hole group 26 or the second connection hole group 27 as needed, allowing for more diverse connection positions between adjacent servos, replacing the traditional single connection position and meeting more connection requirements. Simultaneously, the mounting plate 2 between two adjacent servos can be fixed through the first connection hole 262, or through a combination of the first connection hole 262 and the second connection hole 272, achieving various positional relationships between the mounting plates 2 on different servos.

[0037] Looking back Figure 1 and Figure 3The connecting plate 3 includes a connecting plate 31 and two positioning plates 32. The two positioning plates 32 are located symmetrically on both sides of the connecting plate 31, making the connecting plate 3 U-shaped. The connecting plate 31 and the positioning plates 32 can be fixed by welding, or they can be integrally formed. Each positioning plate 32 has a second mounting hole group 33 with the same structure. The second mounting hole group 33 includes a second clearance hole 331. The second clearance hole 331 has the same shape and size as the first clearance hole 251. The positioning plate 32 has four second mounting holes 332 outside the second clearance holes 331. The second mounting holes 332 are evenly distributed around the circumference of the second clearance holes 331, and the center of the second mounting holes 332 is... The distance to the center of the second clearance hole 331 is the same. The second mounting hole 332 is used to cooperate with the first mounting hole 252 on the mounting plate 2. The bolt passes through the second mounting hole 332 and the first mounting hole 252, which can fix the positioning plate 32 and the baffle 22. The positioning plate 32 can rotate 90 degrees so that the four first mounting holes 252 and the second mounting holes 332 are always in abutting cooperation, which can make the connecting plate 3 perpendicular to the mounting plate 2. At the same time, the mounting plate 2 can be rotated to coincide with the mounting plate 2, or rotated to the side opposite to the mounting plate 2. That is, the connecting plate 3 can be connected to the three sides of the servo housing 1, which solves the problem that there is only one positional relationship between the traditional servo connecting plate 3 and the servo housing 1.

[0038] In addition, a notch 34 is provided on the side of the positioning plate 32 away from the connecting plate 31. The notch 34 is used to reduce the weight of the positioning plate 32. Multiple auxiliary connection holes 35 are provided between two adjacent second mounting holes 332. The figure shows that a total of three auxiliary connection holes 35 are provided on the positioning plate 32, located on the three sides of the positioning plate 32 other than the notch 34. The auxiliary connection holes 35 form a 45° angle with the center distance between the second mounting hole 332 and the second clearance hole 331, and the center distance between adjacent auxiliary connection holes 35 and the second clearance hole 331 forms a 90° angle. The auxiliary connection holes 35 can be rotated to coincide with three of the first mounting holes 252 on the baffle 22. After the bolt passes through the auxiliary connection hole 35, it is threaded to the first mounting hole 252, so that the connecting plate 3 can be installed on the mounting plate 2. This allows the connecting plate 3 and the servo housing 1 to form multiple positional relationships, solving the problem that the traditional servo connecting plate 3 and servo housing 1 can only form one positional relationship.

[0039] A third mounting hole group 36 is provided in the middle of the connecting plate 31. The third mounting hole group 36 includes one third clearance hole 361 and four third mounting holes 362. The third mounting holes 362 are evenly distributed around the third clearance hole 361, and the distance from the center of the third mounting hole 362 to the center of the third clearance hole 361 is the same. The third mounting holes 362 and the third clearance holes 361 facilitate connection and fixation with the connecting plate 3 on the adjacent servo. In addition, the connecting plate 3 between two adjacent servos can be connected and fixed through the third mounting hole 362, realizing various positional relationships between the connecting plates 3 on different servos. Moreover, the first connecting hole 262 on the servo and the third clearance hole 361 on other servos can be connected and fixed, thereby realizing multi-angle installation between adjacent servos.

[0040] The implementation principle of a servo mounting assembly in this application embodiment is as follows: When installing the connecting plate 3, the mounting plate 2 is first fixed to the outside of the servo housing 1, and the bolt passes through the positioning hole 24 and is threadedly connected to the threaded hole 11 on the servo housing 1, so that the mounting plate 2 can be fixed to the servo housing 1.

[0041] When installing the connecting plate 3, the four first mounting holes 252 on the positioning plate 32 can be aligned with the second mounting holes 332 on the mounting plate 2 as needed. Then, the second mounting holes 332 and the first mounting holes 252 can be threaded together with bolts to fix the connecting plate 3 and the mounting plate 2. At the same time, when the auxiliary positioning hole 24 is aligned with the first mounting hole 252, the auxiliary positioning hole 24 and the first mounting hole 252 can be threaded together with bolts to fix the connecting plate 3 and the mounting plate 2. When the second mounting hole 332 or the auxiliary positioning hole 24 is aligned with the first mounting hole 252, the connecting plate 3 is located at different positions on the mounting plate 2, so that the connecting plate 3 and the servo housing 1 can form multiple positional relationships, thus replacing the traditional method of directly fixing the connecting plate 3 to the servo housing 1, which can only form one positional relationship.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
