Description

Technical Field

[0001] This invention relates to the technical field of power supply sockets, and more particularly to sliding contact power supply sockets. Background Technology

[0002] In traditional technology, sliding contact electrical connectors are widely used in various walking robots and other products that require fixed-point power replenishment.

[0003] In existing technologies, robot power supply modes are mainly divided into three types: fixed-point wireless power supply, continuous power supply via sliding contact line, and fixed-point contact power supply. Among them, wireless power supply relies on wireless power supply technology and does not require structural contact; sliding contact line power supply involves laying power supply lines along the robot's travel path and providing power through real-time contact, similar to an old-fashioned tram; fixed-point contact power supply involves setting electrical contacts at a fixed location, and the robot can return to that fixed location for contact-based power supply.

[0004] In point-contact power supply systems, the use of a press-type structure to form an electrical connection can easily lead to poor contact, causing power supply abnormalities and resulting in product power loss and malfunction. Furthermore, the press-type structure is prone to dust accumulation, which can cause poor contact over time, thus affecting the lifespan of the power supply socket. Therefore, an urgent technical solution is to ensure that the power supply socket forms a stable electrical connection with the electrical contacts of the powered product, guaranteeing a normal power supply voltage. Summary of the Invention

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please refer to Figures 1-4 This invention provides a sliding power supply base 100, including a base 110, a first contact 120, a first elastic member 130, a second contact 140, and a second elastic member 150. The first contact 120 includes a first connecting portion 121, a first wiring portion 122, and a first contact portion 123. The first connecting portion 121 is hinged to one side of the base 110, the first wiring portion 122 is detachably connected to an electrical wire, and the first contact portion 123 is disposed away from the first connecting portion 121. The first elastic member 130 abuts against the base 110 and the first contact 120, so that the first contact 120 and the base 110 are elastically hinged. The second contact 140 includes a second connecting portion 141, a second wiring portion 142, and a second contact portion 143. The second connecting portion 141 is hinged to the other side of the base 110. The second wiring portion 142 is detachably connected to an electrical wire. The second contact portion 143 is disposed away from the second connecting portion 141. The first contact portion 123 is engaged with the second contact portion 143 for transmission. At least one of the first contact portion 123 and the second contact portion 143 is used to provide sliding power to the robot. The second elastic member 150 abuts between the base 110 and the second contact 140 so that the second contact 140 is elastically hinged to the base 110. In practical applications, the robot can return to the fixed position of the sliding power supply base 100 for contact charging. When the robot's electrical contact slides against the first contact 120, the first contact 120 is pressed and rotates relative to the base 110. Since the first abutting part of the first contact 120 engages with the second abutting part of the second contact 140, the first contact 120 drives the second contact 140 to rotate relative to the base 110. As a result, the electrical contact comes into contact with the first contact part 123 of the first contact 120 and the second contact part 143 of the second contact 140, forming a connection between the first contact part 123 and / or the second contact part 143 and the electrical contact, thus improving the stable electrical connection structure between the electrical contact and the sliding power supply base 100. In addition, when the robot enters the sliding power supply base 100 from the other side, the robot's electrical contact slides against the second contact 140. The second contact 140 drives the first contact 120 to rotate relative to the base 110, so that the electrical contact can also form a double-point contact with the first contact 123 and the second contact 143, thereby improving the convenience of power supply of the sliding power supply base 100.

[0034] In one possible implementation, the first contact portion 123 has a protrusion 1231, and the second contact portion 143 has a groove 1431. The protrusion 1231 and the groove 1431 engage to form a rotating pair. In specific applications, when the first contact portion 123 is rotated under pressure, the engagement of the protrusion 1231 and the groove 1431 drives the rotation of the second contact portion 143. Alternatively, when the second contact portion 143 is rotated under pressure, the engagement of the protrusion 1231 and the groove 1431 can also drive the rotation of the first contact portion 123. This ensures that the relative rotational displacement of the first contact portion 123 and the second contact portion 143 with the base 110 is synchronized, improving the stability of the electrical connection structure.

[0035] In one possible implementation, the contact points between the protrusion 1231 and the groove 1431 are all smoothly connected by arcs. In specific applications, the edges and contact surfaces of the protrusion 1231 and the groove 1431 are all smoothly connected by arcs to ensure smooth and stable relative rotation between the first contact member 120 and the second contact member 140.

[0036] In one possible implementation, the first contact portion 123 further includes a first convex arc surface 1232, which is located above the protrusion 1231 for external contact; the second contact portion 143 further includes a second convex arc surface 1432, which is located above the groove 1431 for external contact. In specific applications, the robot's electrical contact piece abuts against the first convex arc surface 1232 and the second convex arc surface 1432 respectively, so that the relative sliding of the electrical contact piece with the first convex arc surface 1232 and the second convex arc surface 1432 is smooth. When the electrical contact moves horizontally to the left, it first contacts the first convex arc surface 1232 of the first contact portion 123. Continuing to the left, it presses the first contact member 120 downwards. During this pressing process, the protrusion 1231 of the first contact portion 123 presses the groove 1431 of the second contact portion 143 downwards, and the second contact member 140 also rotates downwards. When the electrical contact moves horizontally to the area where the second contact portion 143 is located, the electrical contact can only contact the first convex arc surface 1232 and the second convex arc surface 1432, and will not contact anything below the convex arc surface that could cause jamming. Once the electrical contact is in position, it forms two pairs of contact with the sliding power supply base 100, which significantly increases the probability of successful contact and reduces the voltage drop caused by contact.

[0037] In one possible implementation, the sliding power supply base 100 further includes a first sliding bearing 160 and a second sliding bearing 170. The first sliding bearing 160 and the second sliding bearing 170 are fixed to both sides of the base 110. A first connecting portion 121 forms a first rotating hole 1211, which is rotatably connected to the first sliding bearing 160. A second connecting portion 141 forms a second rotating hole 1411, which is rotatably connected to the second sliding bearing 170. In specific applications, to make the rotation of the first contact 120 and the second contact 140 relative to the base 110 smoother, the first connecting portion 121 forms a first rotating hole 1211, and the first sliding bearing 160 is fixed on the base 110, allowing smooth rotation of the first rotating hole 1211 relative to the first sliding bearing 160; the second connecting portion 141 forms a second rotating hole 1411, and the second sliding bearing 170 is fixed on the base 110, allowing smooth rotation of the second rotating hole 1411 relative to the second sliding bearing 170.

[0038] In one possible implementation, the sliding power supply socket 100 further includes a first connecting component 180 and a second connecting component 190. The base 110 has a first connecting seat 111 and a second connecting seat 112 protruding from opposite sides. The first connecting component 180 includes a first connecting shaft 181 and a first retaining ring 182. The first connecting shaft 181 passes through the first connecting seat 111. A first sliding bearing 160 is fitted onto the first connecting shaft 181 and located at the first connecting seat 111. The first retaining ring 182 is used to lock the first connecting shaft 181 to the first connecting seat 111. The second connecting component 190 includes a second connecting shaft 191 and a second retaining ring 192. The second connecting shaft 191 passes through the second connecting seat 112. A second sliding bearing 170 is fitted onto the second connecting shaft 191 and located at the second connecting seat 112. The second retaining ring 192 is used to lock the second connecting shaft 191 and the second connecting seat 112. In a specific application, the first connecting seat 111 has a first through hole, and the first connecting shaft 181 passes through the first through hole to install the first sliding bearing 160 at the first connecting seat 111. The first retaining ring 182 is engaged with the end of the first connecting shaft 181 to prevent the first connecting shaft 181 from falling out of the first through hole. The second connecting seat 112 has a second through hole, and the second connecting shaft 191 passes through the second through hole to install the second sliding bearing 170 on the second connecting seat 112. The second retaining ring 192 is engaged with the end of the second connecting shaft 191 to prevent the second connecting shaft 191 from falling out of the first through hole.

[0039] In one possible implementation, the base 110 further includes a first latching seat 113, the first contact member 120 further includes a first latching body 124, one end of the first elastic member 130 is latched to the first latching seat 113, and the other end of the first elastic member 130 is latched to the first latching body 124; the base 110 further includes a second latching seat 114, the second contact member 140 further includes a second latching body 144, two ends of the second elastic member 150 are latched to the second latching seat 114, and the other end of the second elastic member 150 is latched to the second latching body 144. In specific applications, the first elastic member 130 is a first spring, and the second elastic member 150 is a second spring; the first spring is used for the elastic reset of the first elastic member 130; the second spring is used for the elastic reset of the second elastic member 150. Of course, it is conceivable that the first elastic element 130 can be a first torsion spring, and the second elastic element 150 can be a second torsion spring. The first torsion spring is engaged between the first connecting part 121 and the first connecting seat 111, and the second torsion spring is engaged between the second connecting part 141 and the second connecting seat 112. Those skilled in the art should consider this to be within the scope of protection of the solution without any inventive effort.

[0040] In one possible implementation, a first connecting portion 121 is spaced apart from the base 110 and has a first wiring port 1212 for connecting an electrical wire; a second connecting portion 141 is spaced apart from the base 110 and has a second wiring port 1412 for connecting an electrical wire. In specific applications, the spaced-apart first connecting portion 121 above the base 110 restricts the rotation of the first contact member 120, preventing the first spring from falling off; the spaced-apart second connecting portion 141 above the base 110 restricts the rotation of the second contact member 140, preventing the second spring from falling off; after the electrical wires are inserted into the first wiring port 1212 and the electrical wires into the second wiring port 1412, they are fixed by set screws.

[0041] In one possible implementation, the sliding power supply base 100 further includes a third contact 210 and a fourth contact 220, wherein the third contact 210 and the fourth contact 220 are paired and engage with each other, and are insulated from the first contact 120 and the second contact 140 and connected to the base 110; the third contact 210 includes a third connecting portion 211, a third wiring portion 212 and a third contact portion 213, the third connecting portion 211 is hinged to one side of the base 110, the third wiring portion 212 is detachably connected to a reverse-phase wire, and the third contact portion 213 is disposed away from the third connecting portion 211 for external contact power supply; the fourth contact 220 includes a fourth connecting portion 221, a fourth wiring portion 222 and a fourth contact portion 223, the fourth connecting portion 221 is hinged to the other side of the base 110, the fourth connecting portion 221 is detachably connected to a wire, and the fourth contact portion 223 is disposed away from the fourth connecting portion 221 for external contact power supply, and the third abutting portion and the fourth abutting portion are engaged and connected. In specific applications, the third contact 210 and the fourth contact 220 are engaged and connected, and are spaced apart from the first contact 120 and the second contact 140 on the base 110, which is an insulator. The wires connected to the third wiring portion 212 and the fourth wiring portion 222 are in the opposite phase to the wires connected to the first wiring portion 122 and the second wiring portion 142, thereby supplying power to the power supply equipment. It should be understood that the sliding contact power supply base 100 may also include a pair of fifth and sixth contacts that engage with each other, and the third contact 210 and the fourth contact 220 that are paired with the pair of first contacts 120 and second contacts 140, forming a three-phase power supply base.

[0042] In one possible implementation, the base 110 is detachably connected to the ground. In specific applications, the base 110 is fixedly connected to the ground by fixing screws, allowing the operator to quickly install the sliding power supply base 100 at a designated location according to actual needs.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
