[0002] With the further development of artificial intelligence technology, a new type of product, the home companion robot, is gradually emerging. In the field of home companion robots, there is a type of split-type home companion robot, or a robot with detachable modules. This not only allows the robot to have good walking ability, but also allows the main unit of the robot to be removed from the robot base for independent use, which can expand the user's usage scenarios.

[0003] The connection structure between the main unit and the robot base is usually a pogo pin or a spring-loaded contact. For example, the female part of the pogo pin is rigidly fixed to the main unit, and the male part is rigidly fixed to the robot base. However, during robot startup, acceleration, and shutdown, the connection of the existing structure is not stable enough under the action of inertial forces. The main unit may tilt forward or backward, and the connection between the pogo pin or spring-loaded contact may become detached, causing the signal between the main unit and the base to be interrupted, affecting the user experience.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] This application provides a connection component and a split-type robot to improve the stability of the connection structure and reduce the risk of performance degradation caused by unstable connection of the split-type robot.

[0031] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of the connection assembly provided in the embodiment of this application in its separated state. The connection assembly 100 in this embodiment includes a female connector assembly 110 and a male connector assembly 120.

[0032] The female connector assembly 110 includes a female connector 111 and a needle 112, which are fixedly connected. Alternatively, the needle 112 and the female connector 111 can be bonded together with adhesive. The materials of the female connector 111 and the needle 112 may differ. For example, the female connector 111 can be made of plastic, while the needle 112 can be made of metal. Metal facilitates electrical connection, while plastic reduces material costs and provides insulation to the metal connection, minimizing interference during power-on.

[0033] The male connector assembly 120 includes a male connector 121, a spring post 122, and an inner core 123. The spring post 122 is fixedly connected to the inner core 123, which serves as a support structure for the spring post 122. The inner core 123 is elastically connected to the male connector 121. The male connector 121 and the inner core 123 can be made of the same material, such as plastic. The spring post 122 is made of a different material than the male connector 121; it can be made of metal to facilitate electrical connection.

[0034] Please combine Figure 1 And see Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the connection component provided in the embodiment of this application in the connected state. Figure 3 This is another structural schematic diagram of the connecting component provided in the embodiment of this application in the connected state. The connecting component 100 has a connected state. In the connected state of the connecting component 100, the inner core 123 is connected to the female seat 111, and the spring post 122 abuts against the needle 112.

[0035] It should be noted that the connection component 100 in this embodiment is an improvement on the pogo pin, a precision connector used in electronic products such as mobile phones. Pogo pins, also known as spring pins, are widely used in various electronic products for signal transmission and connection. The spring post 122 and the pin 112 are the main components of the pogo pin. The pin 112 has a groove that mates with the spring post 122, enabling both physical and electrical connection. In this embodiment, the component supporting the pin 112 is designated as the female connector 111, and the component supporting the spring post 122 is designated as the male connector 121. Male and female connectors are commonly used in the connection interfaces of electronic devices or mechanical devices. A male connector typically refers to an interface with a protruding plug, while a female connector is an interface with recessed holes that can precisely accommodate the plug of the male connector.

[0036] In this embodiment of the application, in order to improve the connection stability of the connecting component 100 under the impact of inertial force, the male seat is set to a separate form, that is, the male seat 121 and the inner core 123, and the male seat 121 and the inner core 123 are elastically connected. When the inertial force comes, the connected inner core 123 and the female seat 111 can move as a whole relative to the male seat 121, that is, the elastic force is used to cancel the inertial force, thereby reducing the risk of separation of the inner core 123 and the female seat 111 and improving the connection stability.

[0037] In the connection assembly 100 provided in this application embodiment, by elastically connecting the male seat 121 and the inner core 123, when the connection assembly 100 is subjected to an inertial force impact, the inner core 123 and the female seat 111 as a whole can move relative to the male seat 121 and then return to their original position. The elastic force of the elastic connection between the inner core 123 and the male seat 121 can buffer the inertial force, reduce the risk of separation between the inner core 123 and the female seat 111, as well as the spring post 122 and the needle 112, thereby improving the stability and reliability of the connection.

[0038] The elastic connection between the inner core 123 and the male connector 121 can be achieved using a spring. For example, please refer to... Figures 1 to 3 And see Figure 4 As shown, Figure 4 This is an exploded view of the male seat assembly provided in an embodiment of this application. The connecting assembly 100 also includes a spring 130, one end of which is fixed to the inner core 123, and the other end of which is connected to the male seat 121.

[0039] In order to balance the elastic force and the length of the spring 130, a part of the spring 130 can be located inside the inner core 123, that is, the inner core 123 can be made with a hole to accommodate part of the spring 130.

[0040] For example, the male seat 121 includes a top wall 1210 and a side wall 1212. The side wall 1212 may be annular, and the top wall 1210 may be sheet-like. The top wall 1210 is connected to the side wall 1212, and the shape of the top wall 1210 may be similar to the shape of the annular side wall 1212; that is, if the side wall 1212 is annular, the top wall 1210 is circular. The top wall 1210 and the side wall 1212 enclose a receiving space 1214, and the top wall 1210 is provided with a first opening 1211. It is understood that the top wall 1210 and the side wall 1212 may be integrally formed for ease of processing and manufacturing.

[0041] For example, the inner core 123 includes a first sub-part 1230 and a second sub-part 1232 fixedly connected. The first sub-part 1230 is located within the receiving space 1214. The end face of the first sub-part 1230 away from the top wall 1210 can be flush with the end face of the side wall 1212 away from the top wall 1210 to improve the aesthetics and reduce interference with other components. The second sub-part 1232 is located in the first opening 1211, and at least a portion of the second sub-part 1232 protrudes from the top wall 1210 to facilitate connection with the female seat 111. The second sub-part 1232 is provided with a first through hole, and a spring post 122 is disposed within the first through hole and protrudes from the second sub-part 1232 to facilitate connection with the needle 112.

[0042] The connection between the spring post 122 and the second sub-part 1232 can be made by a spring connection, so that the spring post 122 can extend and retract up and down to generate elastic force, making the connection between the spring post 122 and the needle 112 on the female seat 111 reliable.

[0043] It is understood that the shape of the first sub-part 1230 can be the same as the shape of the top wall 1210, and the area of ​​the first sub-part 1230 is smaller than the area of ​​the top wall 1210. There is a space between the first sub-part 1230 and the top wall 1210, which can save materials on the one hand, and provide space for the spring 130 to be installed on the other hand, and also provide deformation space for the spring 130.

[0044] There are at least three possible configurations for spring 130 to meet the needs of different occasions.

[0045] In the first scenario, the connecting assembly 100 includes a first spring. The extension direction of the first spring is perpendicular to the side wall 1212. In this case, the elastic force of the first spring is also perpendicular to the side wall 1212. This configuration can accommodate situations with relatively small inertial forces, and the first spring can help align the male connector 121 and the inner core 123, thereby achieving a stable connection between the female connector 111 and the inner core 123, as well as between the needle 112 and the spring post 122. Regarding the number of first springs, two, three, four, five, or six can be provided. An even number of first springs can be arranged symmetrically or evenly, allowing multiple first springs to provide a uniform elastic force to cope with inertial forces from different directions.

[0046] In the second scenario, the connecting assembly 100 includes a second spring, the extension direction of which is parallel to the side wall 1212. This arrangement allows for the adaptation to situations with large inertial forces, ensuring a stable connection between the female base 111 and the inner core 123, as well as between the needle 112 and the spring post 122. The number of second springs can be set with reference to the number of first springs. Similarly, an even number of second springs can be arranged symmetrically or evenly to handle inertial forces from different directions.

[0047] The third scenario, such as Figure 4 This application describes the third scenario as an example. The connecting component 100 includes a first spring 131 and a second spring 132. The first spring 131 extends in a direction perpendicular to the side wall 1212, and the second spring 132 extends in a direction parallel to the side wall 1212. In this case, it can accommodate a larger inertial force and can help to correct the position between the male seat 121 and the inner core 123, thereby coping with various forces in complex scenarios. The number of first springs 131 can be the same as the number of second springs 132, such as six first springs 131 and six second springs 132 respectively. Multiple first springs 131 and multiple second springs 132 are staggered, that is, one second spring 132 is provided between every two adjacent first springs 131, thereby making uniform use of the elastic force of the springs. From another perspective, based on degrees of freedom, this embodiment of the application provides three sets of spring connections: a set of springs for vertical positions, to which all six second springs 132 belong; a set of springs for horizontal positions, which may include four first springs 131; and a set of springs for front-back positions, which may include two first springs 131. Thus, under the action of the spring force, the inner core 123 and the male seat 121 can maintain a relatively stable position, while the inner core 123 can also move relative to the male seat 121 under the attraction of the female seat 111 spring, thereby ensuring reliable connection.

[0048] Regarding the connection between the needle 112 and the spring post 122, the snap-fit ​​between the two alone cannot effectively cope with the impact of inertial forces. Therefore, this application embodiment also provides other solutions to improve the connection stability.

[0049] For example, please refer to Figures 1 to 4 And see Figure 5 and Figure 6 , Figure 5 for Figure 2 The diagram shows a cross-sectional view of the connecting component along AA. Figure 6This is an exploded structural diagram of the connecting assembly provided in an embodiment of this application. The female seat 111 has a first groove 1110 and a second through hole 1112, which communicates with the first groove 1110. The needle 112 is disposed in the second through hole 1112, and the second sub-part 1232 of the inner core 123 is engaged with the first groove 1110. Thus, the inner core 123 and the female seat 111 are not only connected by the needle 112 and the spring post 122, but also by the second connection between the female seat 111 and the inner core 123. The double connection can improve the stability of the connection.

[0050] In addition to the dual connection, this application also provides a third solution to improve connection stability. For example, the female connector 111 and the inner core 123 are magnetically connected. For instance, a magnetic chuck can be used to magnetically connect the female connector 111 and the inner core 123. The connection assembly 100 also includes a first magnetic chuck 140 and a second magnetic chuck 150. The first magnetic chuck 140 is disposed within the female connector 111, and the second magnetic chuck 150 is disposed within the inner core 123. The first magnetic chuck 140 and the second magnetic chuck 150 are correspondingly disposed and magnetically connected, ensuring a tight connection between the inner core 123 and the female connector 111, and a tight connection between the spring post 122 and the needle 112.

[0051] For example, the female base 111 is also provided with a first annular groove 1114, which is located on the side opposite to the first groove 1110, and the second through hole 1112 is located within the inner circle of the first annular groove 1114. The first annular groove 1114 is used to accommodate the first magnetic member 140, which is also annular to adapt to the shape of the female base 111; the first magnetic member 140 can be flush with the end face surrounding the first annular groove 1114 to prevent interference with other components and improve aesthetics.

[0052] For example, the second sub-part 1232 has a second annular groove 1234, and the first through hole is located in the inner circle of the second annular groove 1234. The opening of the second annular groove 1234 is in the direction away from the female seat 111. The second annular groove 1234 is used to accommodate the second magnetic member 150. The second magnetic member 150 can also be annular, which corresponds to the first magnetic member 140 on the one hand, and can also adapt to the shape of the male seat assembly 120 on the other hand, so as to avoid interference between components.

[0053] This application addresses the instability caused by inertial forces in existing connection structures by providing a flexible pogo pin design. The pogo pin male connector is made into a movable structure with 6 degrees of freedom. Under the magnetic force of the magnetic attractor, the inner core 123 and the female connector 111 can move together. Even if the host moves relative to the base during movement, the initial position of the male connector is guaranteed because the pogo pin male connector is a flexible connection. That is, the moving and fixed parts of the male connector assembly 120 are designed with springs. This ensures that the initial connection position of the male connector does not tilt or drift, and there is no relative movement between the pogo pin male connector and the female connector, thus ensuring connection stability.

[0054] This application also provides a split-type robot, which includes a main unit, a base, and a connecting assembly. The connecting assembly can be referred to the description in the above embodiments, and will not be repeated here. The connecting assembly is fixedly connected to the main unit and the base respectively. For example, the female connector assembly 110 is connected to the main unit, wherein the pin point of the needle 112 on the side near the main unit is connected to the circuit board of the main unit by soldering; the male connector assembly 120 is connected to the base, such as the spring column 122 on the side near the base, which is connected to the main board of the base by soldering. The split-type robot can be used in various ways. When the main unit and the base are connected as one unit by the connecting assembly, the base can support the main unit so that the height of the main unit matches that of the user. The base can also have a walking structure such as wheels, thereby realizing more functions of the split-type robot, such as following the user or moving to a position set by the user. For example, when the main unit is placed on the base, the first magnetic member 140 on the female connector 111 is magnetically connected to the second magnetic member 150 in the inner core 123, thereby making the spring column 122 and the needle 112 firmly connected together. Since the inner core 123 and the male connector 121 are flexibly connected by a spring, they can move relative to each other. The male connector 121 is rigidly connected to the base. Therefore, when the main unit and the base move relative to each other, such as tilting, the female connector 111 and the inner core 123 move together under the magnetic force of the first magnetic suction member 140 and the second magnetic suction member 150, thereby ensuring that the spring post 122 on the inner core 123 and the needle 112 on the female connector 111 are always connected together.
