Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy vehicle charging, specifically to an automatic charging cable embedded robotic arm. Background Technology
[0002] The robotic arm for new energy vehicle charging stations integrates high-precision sensors, AI visual recognition, and multi-axis motion control technologies to achieve automatic plugging and unplugging of charging guns and intelligent management of the charging process.
[0003] A search revealed a utility model patent with announcement number CN213948177U, which discloses an intelligent robotic arm for automatic charging of car charging piles. This invention addresses shortcomings in existing technologies. The arm includes a charging pile body and a vehicle body. The charging pile body is equipped with an image analyzer and a controller. An inner groove is formed on one side of the charging pile body, and a slider is slidably mounted inside the groove. A first swing arm is hinged to one side of the slider, and a second swing arm is hinged to the end of the first swing arm. Through the arrangement of the first, second, and third swing arms, an infrared receiver, an infrared transmitter, the image analyzer, and a camera, after a vehicle parks on one side of the charging pile and a person scans a QR code to make a payment, the internal robotic arm automatically extends. The camera automatically locates the charging port, and once the infrared device aligns, the slider slides out to insert the socket. This design features a high degree of intelligence and facilitates operation.
[0004] In the use of existing car charging robotic arms, the robotic arm needs to move to connect the charging gun to the car's charging port, and the current still needs to be transmitted through a wiring harness. However, the existing wiring harness is usually fixed to the outside of the robotic arm by binding or other methods. This method exposes the wiring harness, which greatly reduces its lifespan and can easily cause the robotic arm and wiring harness to become entangled during operation.
[0005] Therefore, it is necessary to invent a robotic arm with an embedded automatic charging cable to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide an automatic charging wire embedded robotic arm. By embedding the wire harness inside robotic arm one and robotic arm two, and keeping the wire harness taut during operation, the problems of wire harness tangling and exposed wire harness reducing service life are avoided, thereby solving the problems of short wire harness life and low safety in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic charging cable embedded robotic arm, including a robotic arm one, a robotic arm two rotatably connected to one side of the robotic arm one, and a charging gun installed on one side of the robotic arm two;
[0008] The protective component installed inside the robotic arm includes a fixed cylinder, which is installed on the inner wall of the robotic arm. Guide wheels are symmetrically installed on the upper and lower sides of the inner wall of the fixed cylinder. A guide cylinder is installed on the inner wall of the robotic arm away from the fixed cylinder, and guide wheels are also installed inside the guide cylinder.
[0009] The fixing component disposed on the connecting cylinder includes an annular groove formed on the surface of the connecting cylinder. A rotating cylinder is sleeved on the connecting cylinder, and a positioning ring is installed on the inner wall of the rotating cylinder, and the positioning ring is slidably connected to the annular groove.
[0010] Preferably, the protective assembly further includes a sliding cavity, which is formed on the surface of the fixed cylinder. Guide grooves are symmetrically formed on the inner wall of the sliding cavity, and a connecting cylinder is sleeved on the fixed cylinder.
[0011] Preferably, guide blocks are symmetrically installed on the inner wall of the connecting cylinder, and the guide blocks are slidably connected to the corresponding guide grooves. A spring is sleeved inside the sliding cavity, and the two sides of the spring are respectively attached to the inner wall of the connecting cylinder and the inner wall of the sliding cavity.
[0012] Preferably, the fixing component further includes a bevel gear ring, which is installed on the inner wall of the rotating cylinder. Four sets of internally threaded cylinders are arranged in a ring and are connected through the inner wall of the connecting cylinder. A bevel gear is installed on one side of the internally threaded cylinder, and the bevel gear meshes with the bevel gear ring.
[0013] Preferably, a screw is screwed to the side of the internal threaded cylinder away from the bevel gear, a fixing ring is installed on one side of the screw, and guide rods are symmetrically installed on the fixing ring, with the guide rods penetrating the inner wall of the connecting cylinder.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] The wire harness is secured by the fixing rings moving closer together. When the second robotic arm rotates along with the first robotic arm, the wire harness moves inward into the second robotic arm, causing the connecting cylinder to move as a whole. After the second robotic arm resets, the wire harness can also be reset promptly by the spring. This structure firmly fixes the wire harness inside the first and second robotic arms, preventing it from being exposed. The wire harness is always under stress during operation, preventing it from getting tangled and damaged when the first and second robotic arms rotate, thus greatly improving its service life and safety.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-6 The automatic charging cable embedded robotic arm shown includes a robotic arm 001, a robotic arm 101 rotatably connected to one side of the robotic arm 001, and a charging gun installed on one side of the robotic arm 101.
[0027] The protective component 002 installed inside the robotic arm 001 includes a fixed cylinder 201, which is installed on the inner wall of the robotic arm 001. Guide wheels 202 are symmetrically installed on the inner wall of the fixed cylinder 201. A guide cylinder 203 is installed on the inner wall of the robotic arm 001 away from the fixed cylinder 201, and guide wheels 202 are also installed inside the guide cylinder 203.
[0028] The guide wheel 202 and guide cylinder 203 can guide the wire harness, so that the wire harness can always be in the center position of robotic arm 1 001 and robotic arm 2 101.
[0029] The fixing component 003 disposed on the connecting cylinder 206 includes an annular groove 301, which is formed on the surface of the connecting cylinder 206. A rotating cylinder 302 is sleeved on the connecting cylinder 206. A positioning ring 303 is installed on the inner wall of the rotating cylinder 302 and is slidably connected to the annular groove 301.
[0030] The positioning ring 303 and the annular groove 301 work together to enable the rotating drum 302 to rotate stably on the connecting drum 206.
[0031] Furthermore, in the above structure, the protective component 002 also includes a sliding cavity 204, which is formed on the surface of the fixed cylinder 201. Guide grooves 205 are symmetrically formed on the inner wall of the sliding cavity 204, and a connecting cylinder 206 is sleeved on the fixed cylinder 201.
[0032] Furthermore, in the above structure, guide blocks 207 are symmetrically installed on the inner wall of the connecting cylinder 206, and the guide blocks 207 are slidably connected to the corresponding guide grooves 205. A spring 208 is sleeved inside the sliding cavity 204, and the two sides of the spring 208 are respectively attached to the inner wall of the connecting cylinder 206 and the inner wall of the sliding cavity 204.
[0033] The guide block 207 and the guide groove 205 work together to allow the connecting cylinder 206 to slide stably on the fixed cylinder 201, and the spring 208 can keep the position of the connecting cylinder 206.
[0034] Furthermore, in the above structure, the fixing component 003 also includes a bevel gear ring 304, which is installed on the inner wall of the rotating cylinder 302. Four sets of internal threaded cylinders 305 are arranged in a ring and are connected through the inner wall of the connecting cylinder 206. A bevel gear 306 is installed on one side of the internal threaded cylinder 305, and the bevel gear 306 meshes with the bevel gear ring 304.
[0035] The rotation of the rotating drum 302 causes the bevel gear ring 304 to drive the bevel gear 306 to rotate.
[0036] Furthermore, in the above structure, a screw rod 307 is screwed onto the side of the internal threaded cylinder 305 away from the bevel gear 306, a retaining ring 308 is installed on one side of the screw rod 307, and guide rods 309 are symmetrically installed on the retaining ring 308, and the guide rods 309 are connected through the inner wall of the connecting cylinder 206.
[0037] The bevel gear 306 can drive the internal threaded cylinder 305 to rotate, which in turn drives the screw 307 to move, thereby bringing the fixing rings 308 closer together to fix the wire harness. The guide rod 309 can ensure the stable movement of the fixing rings 308.
[0038] The working principle of this practical application is as follows:
[0039] Refer to the instruction manual appendix Figure 1-6 By passing the wire harness between the guide wheel 202 inside the guide cylinder 203 and the fixed cylinder 201, the rotating cylinder 302 is rotated, causing the bevel gear ring 304 to rotate. The bevel gear ring 304 then drives the internal thread cylinder 305 to rotate via the bevel gear 306. The internal thread cylinder 305, through the screw 307, drives the fixed ring 308 to move closer to the wire harness, thus fixing the wire harness. At this time, when the robotic arm 2 101 rotates along with the robotic arm 1 001, the wire harness will be pulled by the robotic arm 2 101. At this time, the connecting cylinder 206 can move to one side to compress the spring 208. After the mechanical arm 2 101 is reset, the connecting cylinder 206 can be reset in time under the action of the spring 208. This structure can firmly fix the wire harness inside the mechanical arm 1 001 and the mechanical arm 2 101, thus preventing it from being exposed. The wire harness can always be under stress during the operation, avoiding the situation where the mechanical arm 1 001 and the mechanical arm 2 101 will entangle and damage the wire harness when rotating, thus greatly improving its service life and safety.
[0040] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
