Description

Technical Field

[0001] This utility model relates to the field of robot charging technology, and in particular to an adaptive charging connector and charging base. Background Technology

[0002] When a robot's battery life is insufficient, it needs to autonomously navigate to recharge. Currently, the mainstream method is to install the charging electrode plates on the robot body. This requires that the electrode contacts on the charging base that cooperate with the electrode plates have a certain buffer function to ensure that the electrode plates and electrode contacts can maintain close contact at all times. However, most of the current electrode contact buffer structures adopt vertical compression. Since vertical compression requires a lot of space, it is not convenient to install the electrode contacts and buffer structure on the charging body of the charging base. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by providing an adaptive charging connector and charging base. The connector's connecting frame can be horizontally installed along its length on the charging body of the charging base, greatly reducing the space occupied by the adaptive charging connector and facilitating its spatial arrangement on the charging body.

[0004] The technical solution adopted in this utility model is as follows: An adaptive charging connector includes a connecting frame, a swing arm, and electrode contacts. The connecting frame is connected to an external charging body along its length. A telescopic component is telescopically connected to the connecting frame along its length, and the telescopic component has a sliding shaft arranged along the width direction of the connecting frame. The swing arm is oscillatingly connected to the connecting frame along its width direction. When the swing arm oscillates, it slides and rotates relative to the sliding shaft to drive the telescopic component to extend and retract relative to the connecting frame. The electrode contacts can contact and conduct electricity with corresponding electrode plates on the charging input terminal of an external robot. The electrode contacts are mounted on the swing arm and electrically connected to the external charging body. They can swing between a first position and a second position with the swing arm under the pressure of the electrode plates. When the electrode contacts swing from the first position to the second position, the height of the electrode contacts relative to the connecting frame gradually decreases. An elastic component is provided between the telescopic component and the connecting frame. The elastic component can provide a force to drive the electrode contacts to swing back to the first position when they swing towards the second position.

[0005] Preferably, the connecting frame has a telescopic groove arranged along its length, and the telescopic member is telescopically connected in the telescopic groove. The top of the connecting frame has a first swing channel arranged on one side of the telescopic groove along its length. The telescopic member has a second swing channel arranged corresponding to the first swing channel. One end of the swing arm has a contact base arranged outside the first swing channel, and the other end is swayably connected to the bottom of the connecting frame along the width direction. The electrode contact is mounted on the contact base. The swing arm has a sliding hinge channel that is slidably connected to the sliding shaft. When the swing arm drives the electrode contact to swing between the first position and the second position, the swing arm is allowed to swing within the first swing channel and the second swing channel, and slide and rotate relative to the sliding shaft through the sliding hinge channel to drive the telescopic member to telescopically move relative to the connecting frame.

[0006] Preferably, the swing arm and the connecting frame are oscillatingly connected by a rotating shaft arranged along the width direction of the connecting frame, the length direction of the sliding hinge channel is arranged radially along the rotating shaft, and the electrode contact is in the first position when the sliding shaft slides to abut against the end of the sliding hinge channel away from the rotating shaft.

[0007] Preferably, the swing arm includes a first arm arranged along the length of the sliding hinge channel and a second arm connected to the end of the first arm away from the rotation axis. The end of the first arm away from the second arm is swayably connected to the bottom of the connecting frame via the rotation axis. The sliding hinge channel is disposed in the first arm, and the contact base is disposed in the end of the second arm away from the first arm. The second arm is arranged at an angle to the first arm, and when the electrode contact is in the first position, the sliding axis is located on the side of the electrode contact away from the second position.

[0008] Preferably, the connecting frame includes a top frame plate, a bottom frame plate, and two side frame plates respectively connected between the two sides of the top frame plate and the two sides of the bottom frame plate. The top frame plate, the bottom frame plate, and the two side frame plates surround to form the telescopic groove. The first swing channel is disposed through the top frame plate. The bottom frame plate extends outward to form a rotating base. A third swing channel corresponding to the rotating base is disposed through the bottom frame plate. The swing arm is swayably connected to the rotating base. When the electrode contact swings between the first position and the second position, the swing arm is allowed to swing within the first swing channel, the second swing channel, and the third swing channel.

[0009] Preferably, the second swing channel extends from the top to the bottom of the telescopic member. Mounting holes are provided on both sides of the second swing channel along the width direction of the connecting frame. Guide channels are provided on both sides of the frame plate along the length direction of the connecting frame. The sliding shaft passes through each mounting hole, guide channel, and sliding hinge channel. When the telescopic member moves in and out relative to the telescopic groove, it can be guided by sliding along the length direction of the guide channel through the sliding shaft.

[0010] Preferably, the connecting frame further includes a baffle arranged in the telescopic groove. When the electrode contact is in the first position, the baffle is located on the side of the electrode contact closer to the second position, and the baffle is connected to the top frame plate and / or the bottom frame plate and / or the side frame plate. The elastic element is arranged between the baffle and one end of the telescopic element.

[0011] Preferably, the electrode contact has a contact surface for contacting the electrode sheet, and the contact surface is configured as a spherical structure.

[0012] Preferably, the contact base is provided with a connector for connecting conductive wires, and the bottom of the electrode contact is recessed with a wiring groove, and the connector extends into the wiring groove and is connected to the wiring groove.

[0013] This utility model also provides a charging base, including a charging body, a positive charging connection terminal, and a negative charging connection terminal. The positive charging connection terminal is disposed on the charging body and is used to contact and conduct electricity with the positive electrode plate of the charging input terminal on an external robot. The negative charging connection terminal is disposed on the charging body and is used to contact and conduct electricity with the negative electrode plate of the charging input terminal on an external robot. The positive charging connection terminal and / or the negative charging connection terminal are configured as the above-mentioned adaptive charging connectors.

[0014] The beneficial effects achieved by this utility model are as follows: The adaptive charging connector provided by this utility model allows the connecting frame to be installed on the external charging body along its length. When the external robot docks with the charging base for charging, the electrode contacts can descend from the first position to the second position under the pressure of the corresponding electrode plate on the robot's charging input end. This causes the swing arm, which is swaying along the width of the connecting frame, to swing. Simultaneously, the swing arm slides and rotates relative to the sliding shaft during its swing, causing the telescopic component to extend and retract relative to the connecting frame. Since there is an elastic element between the telescopic component and the connecting frame, the telescopic component is always supported by the elastic element during its extension and retraction, providing a reaction force that drives the swing arm to swing in the opposite direction. This provides a reaction force for the electrode contacts to rise and reset to the first position, thus providing an elastic buffer for the docking process between the electrode plate and the electrode contacts. This allows the electrode contacts to adapt to the position of the electrode plate and maintain close contact with it at all times, ensuring the reliability of the robot's autonomous charging docking process. Furthermore, since the connecting frame can be installed laterally on the charging body of the charging base along its length, the space height occupied by the adaptive charging connector is greatly reduced, facilitating the spatial arrangement of the adaptive charging connector on the charging body.

Similarly, the terms “an” or “a” and similar terms do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0032] like Figures 1-8As shown in the figure, as an embodiment of this utility model, an adaptive charging connector is provided, including an electrode contact 1, a connecting frame 4, and a swing arm 2. The electrode contact 1 is made of conductive materials such as copper or gold, and can contact and conduct electricity with the corresponding electrode plate on the external robot charging input terminal. The connecting frame 4 can be connected to the external charging body along its length direction. A telescopic member 5 is telescopically connected to the connecting frame 4 along its length direction. The telescopic member 5 is provided with a sliding shaft 9 arranged along the width direction of the connecting frame 4. The swing arm 2 is made of insulating materials such as plastic to prevent the swing arm 2 from becoming electrified when the adaptive charging connector is working. The swing arm 2 is swayably connected to the connecting frame 4 along the width direction of the connecting frame 4. When the swing arm 2 swings, it slides and rotates relative to the sliding shaft 9 to drive the telescopic member 5 to telescopically move relative to the connecting frame 4. Electrode contact 1 is mounted on swing arm 2 and electrically connected to the external charging body. It can swing between a first position and a second position under the pressure of the electrode plate. As electrode contact 1 swings from the first position to the second position, its height relative to the connecting frame 4 gradually decreases. An elastic element 10 is provided between the telescopic member 5 and the connecting frame 4. This elastic element 10 provides a force to drive electrode contact 1 to swing back to the first position when it swings towards the second position. In this embodiment, the adaptive charging connector allows the connecting frame 4 to be mounted on the external charging body along its length. When the external robot docks with the charging base, electrode contact 1 can descend from the first position to the second position under the pressure of the corresponding electrode plate on the robot's charging input end, causing the swing arm 2, which is swayably connected to the connecting frame 4 along its width, to swing. Simultaneously, the swing arm 2 slides and rotates relative to the sliding shaft 9 during its swing, causing the telescopic member 5 to extend and retract relative to the connecting frame 4. Because an elastic element 10 is provided between the telescopic member 5 and the connecting frame 4 to keep electrode contact 1 in the first position, the telescopic member 5 remains stable during its extension and retraction. Supported by the elastic element 10, a reaction force is provided to drive the swing arm 2 to swing in the opposite direction, and a reaction force is provided to the electrode contact 1 to rise and reset to the first position. This provides an elastic buffer for the docking process between the electrode plate and the electrode contact 1, so that the electrode contact 1 can adapt to the position of the electrode plate and maintain close contact with the electrode plate at all times, ensuring the reliability of the robot's autonomous charging docking process. Moreover, since its connecting frame 4 can be installed laterally on the charging body of the charging base along its length, the space height occupied by the adaptive charging connector is greatly reduced, which facilitates the spatial arrangement of the adaptive charging connector on the charging body.

[0033] like Figure 3 , Figure 4As shown, in some specific embodiments, the connecting frame 4 is provided with a telescopic groove arranged along its length direction, and the telescopic member 5 is telescopically connected to the telescopic groove. The top of the connecting frame 4 is provided with a first swing channel 41 arranged on one side of the telescopic groove along its length direction, and the telescopic member 5 is provided with a second swing channel 51 corresponding to the first swing channel 41. One end of the swing arm member 2 forms a contact base 21 arranged outside the first swing channel 41, and the other end is swayably connected to the bottom of the connecting frame 4 along the width direction of the connecting frame 4. Electrode contact 1 is mounted on contact base 21. The swing arm 2 is provided with a sliding hinge channel 22 that is slidably connected to the sliding shaft 9. When the swing arm 2 drives the electrode contact 1 to swing between the first position and the second position, the swing arm 2 is allowed to swing within the first swing channel 41 and the second swing channel 51. It also slides and rotates relative to the sliding shaft 9 through the sliding hinge channel 22 to drive the telescopic member 5 to telescopically move relative to the connecting frame 4. This ensures that the electrode contact 1 can swing between the first position and the second position, while also providing an elastic buffer function by driving the elastic member 10 to elastically deform through the telescopic movement of the telescopic member 5 relative to the connecting frame 4. The structure is also stable. In other embodiments, the connecting frame can also be set as a plate structure or other structures, and the telescopic groove is set on the surface of the connecting frame or through the connecting frame.

[0034] In some specific embodiments, the swing arm 2 and the connecting frame 4 are oscillatingly connected via a rotating shaft 7 arranged along the width direction of the connecting frame 4. The length direction of the sliding hinge channel 22 is arranged radially along the rotating shaft 7. When the sliding shaft 9 slides to abut against the end of the sliding hinge channel 22 away from the rotating shaft 7, the electrode contact 1 is in a first position. Thus, the electrode contact 1 can be held in the first position by the sliding shaft 9 abutting against the end of the sliding hinge channel 22 away from the rotating shaft 7. In addition, since the length direction of the sliding hinge channel 22 is arranged radially along the rotating shaft 7, the setting length of the sliding hinge channel 22 can be shortened, making the overall structure design of the adaptive charging connector lower. Of course, in other embodiments, the length direction of the sliding hinge channel 22 can also be arranged at an angle relative to the radial direction of the rotating shaft 7.

[0035] like Figure 3 , Figure 5As shown, in some specific embodiments, the swing arm 2 includes a first arm 23 arranged along the length of the sliding hinge channel 22 and a second arm 24 connected to the end of the first arm 23 away from the rotation shaft 7. The end of the first arm 23 away from the second arm 24 is swayably connected to the bottom of the connecting frame 4 through the rotation shaft 7. The sliding hinge channel 22 is provided in the first arm 23, and the contact base 21 is provided in the end of the second arm 24 away from the first arm 23. The second arm 24 is arranged at an angle to the first arm 23, and when the electrode contact 1 is in the first position, the sliding shaft 9 is located on the side of the electrode contact 1 away from the second position. That is to say, the electrode contact 1, the sliding shaft 9 and the rotating shaft 7 are arranged in a triangle, so that when the electrode contact 1 swings from the first position to the second position, it can drive the sliding hinge channel 22 to swing around the axis of the rotating shaft 7. At the same time, the sliding hinge channel 22 rotates and slides relative to the sliding shaft 9, and pushes the sliding shaft 9 and the telescopic member 5 to move in extension and retraction relative to the telescopic groove as a whole. At this time, the sliding shaft 9 slides along the sliding hinge channel 22 towards the direction closer to the rotating shaft 7, ensuring that the electrode contact 1 can swing from the first position to the second position.

[0036] In some specific embodiments, the connecting frame 4 includes a top frame plate, a bottom frame plate, and two side frame plates respectively connected between the two sides of the top frame plate and the two sides of the bottom frame plate. The top frame plate, the bottom frame plate, and the two side frame plates surround to form the telescopic groove. The first swing channel 41 is disposed through the top frame plate. The bottom frame plate extends outward to form a rotating base 43. A third swing channel 42 corresponding to the rotating base 43 is disposed through the bottom frame plate. The swing arm 2 is swayably connected to the rotating base 43. When the electrode contact 1 swings between the first position and the second position, the swing arm 2 is allowed to swing within the first swing channel 41, the second swing channel 51, and the third swing channel 42. In this embodiment, the swing arm 2 is oscillatingly connected to the rotating base 43 extending beyond the base plate via the rotating shaft 7. This ensures that the electrode contact 1 can swing between the first and second positions, while making the arrangement of the swing arm 2 and the connecting frame 4 more compact. This reduces the height gap between the base plate and the top plate, thereby reducing the space occupied by the connecting frame 4 and facilitating the spatial arrangement of the adaptive charging connector on the charging body. Both ends of the rotating shaft 7 are respectively limited to the outer sides of the rotating base 43 and the swing arm 2 by rotating limiting heads 8. At least one rotating limiting head 8 is detachably connected to the rotating shaft 7. This detachable connection can be a threaded connection, which not only facilitates the assembly or disassembly of the rotating shaft 7 but also allows adjustment of the preload of the assembled rotating shaft 7.

[0037] like Figure 3As shown, in some specific embodiments, the second swing channel 51 extends from the top to the bottom of the telescopic member 5. Mounting holes 52 are respectively provided on the side walls of the second swing channel 51 along the width direction of the connecting frame 4. Guide channels 44 are respectively provided on the side plates along the length direction of the connecting frame. The sliding shaft 9 passes through each mounting hole 52, guide channel 44, and sliding hinge channel 22. When the telescopic member 5 moves telescopically relative to the telescopic groove, it can be guided by sliding the sliding shaft 9 along the length direction of the guide channel 44, allowing the telescopic member 5 to move stably along a preset motion trajectory, thus improving the stability of the electrode contact 1 when swinging between the first and second positions. Both ends of the sliding shaft 9 are respectively limited to the outside of the two guide channels 44 by sliding limit heads 6. At least one sliding limit head 6 is detachably connected to the sliding shaft 9. This detachable connection can be a threaded connection, which not only facilitates the assembly or disassembly of the sliding shaft 9 but also allows adjustment of the preload of the assembled sliding shaft 9. In addition, in this embodiment, the sliding shaft 9 serves as both a connecting structure for the swing arm 2 to drive the telescopic member 5 to telescopically move relative to the connecting frame 4, and a connecting and guiding structure for the telescopic member 5 to telescopically move relative to the connecting frame 4 along the guide channel 44. It has the effect of multiple uses and facilitates the assembly or disassembly of the adaptive charging connector. In other embodiments, one connecting structure can be provided to slide and rotate in connection with the sliding hinge channel 22, and another connecting structure can be provided to slide in connection with the guide channel 44.

[0038] In some specific embodiments, the connecting frame 4 also includes a baffle 45 arranged in the telescopic groove. When the electrode contact 1 is in the first position, the baffle 45 is located on the side of the electrode contact 1 closer to the second position, and the baffle 45 is connected to one end of the top frame plate, the bottom frame plate, and the side frame plate, and the connection is firm and solid. The elastic element 10 is arranged between the baffle 45 and one end of the telescopic element 5. The elastic element 10 is set as a spring. The telescopic element 5 has a positioning boss 53 at one end near the baffle 45. One end of the elastic element 10 abuts against the baffle 45 and is limited by the baffle 45. The other end is sleeved outside the positioning boss 53 and abuts against the telescopic element 5. When the electrode contact 1 swings from the first position to the second position, the telescopic element 5 is driven to move in a direction closer to the baffle 45 relative to the connecting frame 4 through the swing arm 2. At the same time, the telescopic element 5 compresses the elastic element 10 and provides a reaction force to push the electrode contact 1 to swing towards the first position through the elastic element 10. In other embodiments, the elastic member 10 may also be configured as other structures that can provide elastic force, such as elastic silicone. The baffle 45 may also be connected to the middle position or other positions of the top frame plate, the bottom frame plate and the side frame plate, or the baffle 45 may be connected to only one or two of the top frame plate, the bottom frame plate and the side frame plate, or it may be used to limit one end of the elastic member 10.

[0039] In some specific embodiments, the electrode contact 1 has a contact surface for contacting the electrode plate. This contact surface is configured as a spherical structure, which enables the electrode contact 1 to maintain close contact with the electrode plate at all times during its swinging motion, thereby ensuring the reliability of the robot's autonomous charging docking process. Of course, in other embodiments, the contact surface can also be configured as an arcuate structure or other shaped structure that enables the electrode contact 1 to maintain close contact with the electrode plate at all times during its swinging motion.

[0040] In some specific embodiments, the contact base 21 is provided with a connector 3 for connecting a conductive wire (not shown in the figure). The conductive wire is used to connect to an external charging body. The bottom of the electrode contact 1 is recessed with a wiring groove. The connector 3 extends into the wiring groove and connects with the wiring groove, thereby realizing the electrical connection between the electrode contact 1 and the conductive wire, and making the electrode contact 1 electrically connected to the external charging body.

[0041] like Figure 3 , Figure 7 As shown, in some specific embodiments, the connector 3 includes a terminal post 31 and a limiting platform 32 protruding from the outer periphery of the terminal post 31. The electrode contact 1 is arranged on the top side of the contact base 21. The contact base 21 has a through-hole corresponding to the wiring groove. The terminal post 31 extends into the wiring hole and the wiring groove and connects with the wiring groove to conduct electricity. After connection, the contact base 21 is axially limited between the limiting platform 32 and the electrode contact 1. In this embodiment, the connector 3 serves as both a conductive connection structure for connecting the electrode contact 1 to the conductive wire and a connection structure for connecting the electrode contact 1 to the contact base 21, achieving a multi-purpose effect and facilitating the assembly or disassembly of the adaptive charging connector.

[0042] In some specific embodiments, the terminal block 31 is threadedly connected to the wiring slot, facilitating the connection or disconnection of the electrode contact 1 and the wiring component 3. One side of the wiring component 3 is configured as a first plane, and one side of the wiring hole is configured as a second plane corresponding to the first plane. The wiring component 3 and the wiring hole abut against each other through the first plane and the second plane to prevent the wiring component 3 from rotating relative to the wiring hole, thereby preventing the wiring component 3 from rotating relative to the wiring hole when connecting the electrode contact 1, making it more convenient to assemble the electrode contact 1.

[0043] like Figures 8-10As shown, in another embodiment of this utility model, a charging base is also provided, including a charging body 100, a positive charging connection terminal 101, and a negative charging connection terminal 102. The positive charging connection terminal 101 is disposed on the charging body 100 and is used to contact and conduct electricity with the positive electrode plate of the charging input terminal on an external robot. The negative charging connection terminal 102 is disposed on the charging body 100 and is used to contact and conduct electricity with the negative electrode plate of the charging input terminal on an external robot. The positive charging connection terminal 101 and the negative charging connection terminal 102 are respectively configured as adaptive charging connectors provided by this utility model, thereby greatly reducing the space height occupied by the positive charging connection terminal 101 and the negative charging connection terminal 102, and facilitating the spatial arrangement of the positive charging connection terminal 101 and the negative charging connection terminal 102 on the charging body 100. Of course, in some other embodiments, only either the positive charging connection terminal 101 or the negative charging connection terminal 102 may be configured as the adaptive charging connector provided by this utility model.

[0044] In some specific embodiments, the positive charging connection 101 and the negative charging connection 102 are disposed on the inner side of the top wall of the charging body 100. The top wall of the charging body 100 is provided with swing openings for the swing arms 2 of the positive charging connection 101 and the negative charging connection 102 to extend out of the charging body 100, so that the electrode contacts 1 are arranged outside the charging body 100. When the electrode contacts 1 swing between the first position and the second position, the swing arms 2 are allowed to swing within the swing openings. At the same time, most of the structure of the positive charging connection 101 and the negative charging connection 102 is hidden inside the charging body 100, reducing the space occupied by the positive charging connection 101 and the negative charging connection 102 on the external space of the charging body 100.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.

[0046] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
