Description

Technical Field

[0001] The present invention relates to the technical field of robot battery components, and specifically to a protective battery component for a service robot and its usage method. Background Art

[0002] Service robots are a young member of the robot family and there is no strict definition. Different countries have different understandings of service robots.

[0003] They can be divided into service robots in professional fields and personal / home service robots. The application scope of service robots is very wide, and they are mainly engaged in maintenance, repair, transportation, cleaning, security, rescue, guardianship and other work.

[0004] For the battery components of existing service robots, there are the following problems: 1. The battery connection wires will cause the cross-sectional area of the conductor to change due to wrinkles and bends, and the current path becomes irregular when passing through these parts, thus increasing the resistance; 2. When the wire is bent repeatedly or has severe wrinkles, the metal wires inside the conductor may experience fatigue fracture. Summary of the Invention

[0013] Preferably, a lead screw is threadedly connected to one end of the frame away from the smooth rod. A second rail is connected to the outside of the lead screw through a bearing, and the second rail is fixedly connected to the top of the end cover. A first flattening block is inserted into the frame. A double inclined block is extrusion-fitted to the outside of the first flattening block, and the double inclined block is fixedly connected to the top of the end cover. One end of the first flattening block away from the double inclined block is extrusion-fitted to the second wire.

[0014] Preferably, a folding rod is fixedly connected to the top of the first flattening block. One end of the folding rod away from the first flattening block is fixedly connected to a piston. The piston is slidably fitted inside the frame. One end of the piston away from the folding rod is fixedly connected to a return spring, and the other end of the return spring away from the piston is fixedly connected inside the frame.

[0015] Preferably, an inclined surface column is slidably fitted inside the frame. A limited-slip rod is fixedly connected to the outside of the inclined surface column. One end of the limited-slip rod away from the inclined surface column is slidably fitted inside the frame. The bottom of the inclined surface column is extrusion-fitted to a compensation block. The inner side of the compensation block is fixedly connected to a second flattening block. The second flattening block is inserted into the frame, and the inner side of the second flattening block is extrusion-fitted to the second wire.

[0016] Preferably, the limiting mechanism further includes a top rail, which is fixedly connected to the top of the end cover. A sliding limit seat is slidably fitted inside the top rail. A first magnet is fixedly connected to the top of the sliding limit seat. An extension rod is fixedly connected to the inner side of the sliding limit seat, and a perforation is provided on the surface of the extension rod.

[0017] Preferably, a sleeve plate is inserted into the outside of the extension rod. A fixed limit seat is fixedly connected to the top of the sleeve plate. A second magnet is fixedly connected to the top of the fixed limit seat. The outside of the fixed limit seat is extrusion-fitted to the first wire. A limited insertion rod penetrates through the surface of the fixed limit seat. The bottom of the limited insertion rod is extrusion-fitted to the extension rod, and a connecting rod part is fixedly connected to the top of the limited insertion rod.

[0018] Preferably, the protection mechanism includes a double-headed rod fixedly connected to the outside of the frame. A slant pressure plate is fixedly connected to the bottom of the double-headed rod. A double-sided plate is squeezed and adapted to the bottom of the slant pressure plate. A reset rod is inserted into the outside of the double-sided plate, and the reset rod is fixedly connected to the outside of the battery box.

[0019] Preferably, both ends of the double-sided plate are squeezed and adapted to square rods. A moving block is fixedly connected to the inner side of the square rod. One end of the moving block away from the square rod is slidably adapted to a fixed rail, and the fixed rail is fixedly connected to the outside of the battery box. An elastic telescopic rod is fixedly connected to the end of the square rod away from the double-sided plate, and a pressing plate is fixedly connected to the end of the elastic telescopic rod away from the square rod.

[0020] A usage method of a protective battery assembly for a service robot includes the following steps:

[0021] Step 1: Flattening protection. By the inward movement of the frame, the first flattening block inserted inside it will be squeezed by the double inclined blocks. Immediately afterwards, the first flattening block will move towards the inner cavity of the frame and slightly squeeze the second electric wire to straighten and comb the bent state of the electric wire.

[0022] Step 2: Limiting protection. When the perforation opened on the outer side of the extension rod moves directly below the limiting insertion rod, the limiting insertion rod will pass through the perforation and perform a limiting process on it. At this moment, the sliding limiting seat and the fixed limiting seat will squeeze and limit the first electric wire.

[0023] Step 3: Stable protection. The square rod squeezed by the double-sided plate will move outward along the fixed rail along with the moving block. Subsequently, the elastic telescopic rod fixedly connected to the outer end of the square rod will drive the pressing plate to move outward. Therefore, when the entire battery assembly is placed inside the robot, the pressing plate will extend and squeeze against the inner wall of the robot.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. By the first flattening block being squeezed by the double inclined blocks and the compensation block connected to the second flattening block being squeezed by the inclined surface column, the first flattening block and the second flattening block move inward together and slightly squeeze the second electric wire, thereby straightening and combing the bent state of the second electric wire, and at the same time removing impurities and dust on its surface.

[0026] 2. Under the action of the attraction between the first magnet and the second magnet, the sliding limiting seat will move towards the fixed limiting seat, so that the sliding limiting seat and the fixed limiting seat squeeze and limit the first electric wire, thereby limiting the tails of the first electric wire and the second electric wire connected to other components, preventing the electric wires from falling off and breaking due to the shaking or falling of the robot.

[0027] 3. Through the stretching of the telescopic rod and the characteristics of the universal joint, the plug can be deflected and extended arbitrarily, thus preventing the wire connected to it from bending and wrinkling due to the shaking of the plug, and then cracking. At the same time, the plug can also be connected to the external wiring of the robot with any length and at different positions.

[0028] 4. By the outward extension of the pressing plate and the extrusion with the inner wall of the robot, the battery module will be tightly stuck inside the robot, preventing the battery module from flipping and colliding due to the impact and shaking of the robot. In addition, the elastic telescopic rod not only plays a role in buffering the impact force, but also plays a role in compensating the distance between the inner wall of the robot and the pressing plate.

[0045] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features, and it should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0046] Please refer to Figures 1 to 15 , the present invention provides a technical solution: as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it includes a flattening mechanism 3 which is used for combing the electric wire and covering and protecting the damaged part. A end cover 2 is fixedly installed at the bottom of the flattening mechanism 3;

[0047] A limiting mechanism 4 which is used for limiting and positioning the connection part of the electric wire;

[0048] A protection mechanism 6 which is used for strengthening the stability of the battery assembly;

[0049] A battery box 1 is arranged at the bottom of the end cover 2. The protection mechanism 6 is symmetrically arranged at both ends of the battery box 1. The limiting mechanism 4 is fixedly installed on the end cover 2. A plug 5 is arranged at the top of the end cover 2. The plug 5 is fixedly connected with the limiting mechanism 4. A collecting box 7 is fixedly connected to the end cover 2. A handle 8 is rotatably connected inside the collecting box 7.

[0050] Among them, the flattening mechanism 3 includes a first connector 31 and a second connector 303. The bottoms of the first connector 31 and the second connector 303 are both connected to the battery box 1. A first electric wire 32 is fixedly connected to the top of the first connector 31. A second electric wire 302 is fixedly connected to the top of the second connector 303.

[0051] A flattening component 33 is arranged on the outside of the first wire 32. An adjusting rail 34 is slidably fitted to the top of the flattening component 33. A frame 35 is fixedly connected to the top of the adjusting rail 34. One end of the bottom of the frame 35 is slidably fitted with a smooth rod 36. A first rail 37 is fixedly connected to the outside of the smooth rod 36. The first rail 37 is fixedly connected to the top of the end cover 2. A lead screw 38 is threadedly connected to the end of the frame 35 away from the smooth rod 36. A second rail 39 is connected to the outside of the lead screw 38 through a bearing. The second rail 39 is fixedly connected to the top of the end cover 2. A first flattening block 30 is inserted into the frame 35. A double inclined block 301 is extrusion-fitted to the outside of the first flattening block 30. The double inclined block 301 is fixedly connected to the top of the end cover 2. One end of the first flattening block 30 away from the double inclined block 301 is extrusion-fitted to the second wire 302. A folding rod 304 is fixedly connected to the top of the first flattening block 30. One end of the folding rod 304 away from the first flattening block 30 is fixedly connected to a piston 305. The piston 305 is slidably fitted inside the frame 35. One end of the return spring 306 away from the piston 305 is fixedly connected to the inside of the frame 35. An inclined surface column 307 is slidably fitted inside the frame 35. A limited-slip rod 308 is fixedly connected to the outside of the inclined surface column 307. One end of the limited-slip rod 308 away from the inclined surface column 307 is slidably fitted inside the frame 35. The bottom of the inclined surface column 307 is extrusion-fitted to a compensation block 309. A second flattening block 300 is fixedly connected to the inside of the compensation block 309. The second flattening block 300 is inserted into the frame 35. The inside of the second flattening block 300 is extrusion-fitted to the second wire 302. By rotating the lead screw 38 forward, the frame 35 threadedly connected thereto will move inward along the second rail 39. At the same time, the other end of the frame 35 will move inward synchronously along the smooth rod 36. As the frame 35 moves inward, the first flattening block 30 inserted into it will be squeezed by the double inclined block 301. The contact surfaces between the first flattening block 30 and the double inclined block 301 are both inclined surfaces. Then the first flattening block 30 will move towards the inner cavity of the frame 35 and slightly squeeze the second wire 302. At the same time, the folding rod 304 fixedly connected to the top of the first flattening block 30 will drive the piston 305 to extend into the frame 35. Then the piston 305 will compress the return spring 306. The return spring 306 plays a role in resetting the piston 305. And the inside of the frame 35 is filled with gas. Therefore, the compressed gas will squeeze the inclined surface column 307 downward. Then the inclined surface column 307 will squeeze the compensation block 309 downward. The compensation block 309 is connected to the second flattening block 300. Therefore, the second flattening block 300 will move in the opposite direction to the first flattening block 30 and slightly squeeze the second wire 302 together, so as to move inward together with the first flattening block 30 and the second flattening block 300 and slightly squeeze the second wire 302, straightening and combing the bent state of the second wire 302.Meanwhile, the impurities and dust on its surface are removed. The above operations also apply to the first wire 32. Additionally, when new wires are in short supply, the first flattening block 30 and the second flattening block 300 also play a role in urgently protecting the cracked parts of the wire to prevent electric leakage. Both the first flattening block 30 and the second flattening block 300 are made of insulating materials.

[0052] Such as Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the limiting mechanism 4 further includes a top rail 41. The top rail 41 is fixedly connected to the top of the end cover 2. A sliding limit seat 42 is slidably fitted inside the top rail 41. A first magnet 43 is fixedly connected to the top of the sliding limit seat 42. An extension rod 44 is fixedly connected to the inner side of the sliding limit seat 42. A perforation 45 is formed on the surface of the extension rod 44. A sleeve plate 46 is inserted outside the extension rod 44. A fixed limit seat 47 is fixedly connected to the top of the sleeve plate 46. A second magnet 48 is fixedly connected to the top of the fixed limit seat 47. The outside of the fixed limit seat 47 is in extrusion fit with the first wire 32. A limit insertion rod 49 penetrates through the surface of the fixed limit seat 47. The bottom of the limit insertion rod 49 is in extrusion fit with the extension rod 44. A connecting rod member 40 is fixedly connected to the top of the limit insertion rod 49. Then, manually move the sliding limit seat 42 inward along the top rail 41. At this time, the first magnet 43 fixedly connected to the top of the sliding limit seat 42 will move towards the direction of the second magnet 48. When the distance between the two magnets reaches a certain extent, the adsorption force between them will drive the sliding limit seat 42 to automatically move inward along the top rail 41. At the same time, the extension rod 44 fixedly connected to the inner side of the sliding limit seat 42 will pass through the sleeve plate 46 and move inward. When the perforation 45 formed on the outside of the extension rod 44 moves to directly below the limit insertion rod 49, the limit insertion rod 49 will pass through the perforation 45 and perform a limiting process on it. At this moment, the sliding limit seat 42 and the fixed limit seat 47 will perform an extrusion limiting process on the first wire 32, thereby playing a role in limiting the tails of the first wire 32 and the second wire 302 connected to the other components, preventing the wires from falling off and cracking due to the shaking or falling of the robot.

[0053] The limiting mechanism 4 includes a connecting member 401. The number of the connecting members 401 is two, and they are respectively fixedly connected to the first wire 32 and the second wire 302. One end of the connecting member 401 away from the second wire 302 is fixedly connected with a universal joint seat 402. The outer side of the universal joint seat 402 is rotatably connected with a telescopic rod 403. One end of the telescopic rod 403 away from the universal joint seat 402 is fixedly connected with an inner disc 404. The outer side of the inner disc 404 is fixedly connected to the plug 5. By manually pulling the plug 5, the inner disc 404 fixedly connected inside it will stretch the telescopic rod 403, causing the telescopic rod 403 to elongate. At the same time, the other end of the telescopic rod 403 is connected to the universal joint seat 402. Therefore, the plug 5 can deflect and extend arbitrarily, thus preventing the wires connected to it from bending and wrinkling due to the shaking of the plug 5, and then cracking. At the same time, the plug 5 can also be connected to the external wires of the robot with any length and at different positions.

[0054] As Figure 13 , Figure 14 and Figure 15 shown, the protection mechanism 6 includes a double-headed rod 61. The double-headed rod 61 is fixedly connected to the outer side of the frame 35. The bottom of the double-headed rod 61 is fixedly connected with an inclined pressure plate 62. The bottom of the inclined pressure plate 62 is in extrusion fit with a double-sided plate 63. The outer side of the double-sided plate 63 is inserted with a reset rod 64. The reset rod 64 is fixedly connected to the outer side of the battery box 1. Both ends of the double-sided plate 63 are in extrusion fit with square rods 65. The inner side of the square rods 65 is fixedly connected with moving blocks 66. One end of the moving block 66 away from the square rod 65 is slidably fitted with a fixed rail 67. The fixed rail 67 is fixedly connected to the outer side of the battery box 1. One end of the square rod 65 away from the double-sided plate 63 is fixedly connected with an elastic telescopic rod 68. One end of the elastic telescopic rod 68 away from the square rod 65 is fixedly connected with a pressing plate 69. As the frame 35 moves inward, the double-headed rod 61 fixedly connected to the outer side will move inward together, and the inclined pressure plate 62 fixedly connected to the bottom end of the double-headed rod 61 will also move inward together and press the double-sided plate 63 downward. Then the double-sided plate 63 will move downward along the reset rod 64 and press the square rod 65. The square rod 65 under extrusion will move outward along the fixed rail 67 with the moving block 66. Then the elastic telescopic rod 68 fixedly connected to the outer end of the square rod 65 will drive the pressing plate 69 to move outward. Therefore, when the entire battery assembly is placed inside the robot, the pressing plate 69 will protrude and press against the inner wall of the robot, so that the battery assembly will be tightly stuck inside the robot, preventing the battery assembly from flipping and colliding due to the impact and shaking of the robot. In addition, the elastic telescopic rod 68 not only plays a role in buffering the impact force, but also plays a role in compensating the distance between the inner wall of the robot and the pressing plate 69.

[0055] When the present invention is in use: First, rotate the lead screw 38 in the forward direction, so that the frame 35 threadedly connected thereto will move inward along the second rail 39. At the same time, the other end of the frame 35 will move inward synchronously along the optical rod 36. As the frame 35 moves inward, the first flattening block 30 inserted therein will be squeezed by the double inclined block 301. Immediately afterwards, the first flattening block 30 will move towards the inner cavity of the frame 35 and slightly squeeze the second electric wire 302. At the same time, the folding rod 304 fixedly connected to the top of the first flattening block 30 will drive the piston 305 to extend into the frame 35. The inside of the frame 35 is filled with gas. Therefore, the compressed gas will squeeze the inclined surface column 307 downward. Subsequently, the inclined surface column 307 will squeeze the compensation block 309 downward. The compensation block 309 is connected to the second flattening block 300. Therefore, the second flattening block 300 will move in the opposite direction to the first flattening block 30 and together slightly squeeze the second electric wire 302.

[0056] Subsequently, move the sliding limit seat 42 inward along the top rail 41. At this time, the first magnet 43 fixedly connected to the top of the sliding limit seat 42 will move towards the direction of the second magnet 48. When the distance between the two magnets reaches a certain extent, the adsorption force between the two will drive the sliding limit seat 42 to automatically move inward along the top rail 41. At the same time, the extension rod 44 fixedly connected to the inner side of the sliding limit seat 42 will pass through the sleeve plate 46 and move inward. When the through hole 45 opened on the outer side of the extension rod 44 moves to directly below the limit insertion rod 49, the limit insertion rod 49 will pass through the through hole 45 and perform a limiting process on it. At this moment, the sliding limit seat 42 and the fixed limit seat 47 will perform a squeezing and limiting process on the first electric wire 32.

[0057] By manually pulling the plug 5, the inner disk 404 fixedly connected inside it will stretch the telescopic rod 403, causing the telescopic rod 403 to elongate. At the same time, the other end of the telescopic rod 403 is connected to the universal joint seat 402. Therefore, the plug 5 can deflect and extend arbitrarily. As the frame 35 moves inward, the double-headed rod 61 fixedly connected to the outside will move inward together. The inclined pressure plate 62 fixedly connected to the bottom end of the double-headed rod 61 will also move inward together and squeeze the double-sided plate 63 downward. Subsequently, the double-sided plate 63 will move downward along the reset rod 64 and squeeze the square rod 65. The squeezed square rod 65 will move outward along the fixed rail 67 with the moving block 66. Subsequently, the elastic telescopic rod 68 fixedly connected to the outer end of the square rod 65 will drive the abutting plate 69 to move outward.

[0058] The above-mentioned embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concepts and without creative labor, all kinds of transformations made will fall within the scope of protection of the present invention.
