Description

Technical Field

[0001] The utility model relates to the technical field of robots, and more particularly to a display quick-disassembly device used by an inspection robot. Background Art

[0002] As robotics technology matures, robots are becoming more sophisticated in their work. For inspection robots, sometimes a display needs to be added to facilitate interaction with humans. At the same time, the display needs to be removed for debugging or maintenance.

[0003] When installing or adding a display to an inspection robot using existing technology, in order to avoid making major changes to the inspection robot's structure, the only option is to drill holes in its outer shell. When installing a display, the robot's outer shell needs to be disassembled and then fixed to the robot's metal frame, which is very labor-intensive. When the display is no longer needed, disassembling the display will expose the previously opened avoidance holes, affecting the product's appearance. Furthermore, when installing or removing the display, the screws are used to operate, and the structural parts that fix the display are relatively scattered and cannot be assembled and disassembled together with the display. If a plastic lock is used as a quick-release structure, due to the limitations of the plastic's properties, it cannot withstand large loads, nor can it guarantee the stability and reliability of the inspection robot at low speeds.

[0045] According to the embodiment of the present invention, the display quick-release device is applied to an inspection robot. The body of the inspection robot is provided with a replacement port 10 , and two spaced-apart columns 11 are provided in the replacement port 10 . The display quick-release device includes a display module 20 and a groove portion 30 .

[0046] Specifically, the display module 20 includes a display 21, and a U-shaped support arm 22 with an opening facing away from the display 21 is fixed on the back of the display 21, and a protrusion 23 is provided at the bottom of the U-shaped support arm 22; the groove portion 30 is fixed on the column 11, and its position corresponds to the protrusion 23. When the two side walls of the U-shaped support arm 22 contact and insert with the two outer walls of the column 11, the protrusion 23 is engaged with the groove portion 30.

[0047] In other words, the display quick-release device according to the embodiment of the present invention is mainly composed of a display module 20 and a groove portion 30, and is mainly used in patrol robots. The body of the patrol robot is provided with a replacement port 10, and the replacement port 10 is generally located at the back of the robot body to avoid affecting the appearance of the front. Two spaced columns 11 are provided in the replacement port 10. The columns 11 can utilize the internal structural skeleton of the robot or can be designed and reserved separately. In order to save the cost of the robot, this case preferably utilizes the internal structural skeleton of the robot as the columns 11, and the material is preferably metal, which can better ensure the overall strength. Among them, if Figure 1 As shown, two columns 11 are spaced apart, and the groove portion 30 is fixed on the columns, preferably fixed on the columns 11 by screws.

[0048] like Figure 2 As shown, the display module 20 includes a display 21. A U-shaped support arm 22 is secured to the back of the display 21, with its opening facing away from the display 21. The bottom of the U-shaped support arm 22 is positioned adjacent to the display. A protruding buckle 23 is provided at the bottom of the U-shaped support arm 22 and is secured to the U-shaped support arm via screws. The position of the groove 30 on the column 11 corresponds to the protruding buckle 23. The distance between the inner edges of the two side walls of the U-shaped support arm 22 is slightly larger than the distance between the two outer walls formed by the two columns 11. When the two side walls of the U-shaped support arm 22 contact and insert into the two outer walls of the column 11, the outer walls of the two columns 11 form a sliding guide for the U-shaped support arm 22, guiding the side walls of the U-shaped support arm 22 to be vertically inserted into the replacement port 10 along the outer walls of the two columns 11. At this time, the convex buckle 23 on the back of the display 21 is inserted into the groove portion 30 on the column 11, and the convex buckle 23 and the groove portion 30 are snapped together. At this time, the two outer walls of the column 11 form a positioning restriction on the side walls of the U-shaped support arm 22, and the display module 20 is fixed by the groove portion 30 and the outer walls of the column 11, and the operation can be completed without tools.

[0049] Therefore, according to the display quick-release device of the present invention, it is applied to a patrol robot. The body of the patrol robot is provided with a replacement port 10, and two spaced-apart columns 11 are provided in the replacement port 10. The display quick-release device includes a display module 20 and a groove portion 30. The groove portion 30 is provided on the column of the patrol robot. The back of the display module 20 is fixed with a U-shaped support arm 22 with an opening facing away from the display 21 and a convex buckle 23 corresponding to the position of the groove portion 30. When the two side walls of the U-shaped support arm 22 contact and insert with the two outer side walls of the column 11, the convex buckle 23 is engaged with the groove portion 30. The display quick-release device of the present invention guides the convex buckle 23 on the display module 20 to be inserted into the groove portion 30 on the column 11 through the contact guiding effect between the two side walls of the U-shaped support arm 22 and the outer side walls of the column 11. At the same time, the two outer side walls of the column 11 form positioning restrictions on the side walls of the U-shaped support arm 22. The display quick-disassembly device of the utility model has a simple and reliable structure, can be quickly disassembled and assembled without tools, and has a firm and stable fixing structure without affecting the appearance of the product.

[0050] According to one embodiment of the present invention, the groove portion 30 includes a base 31, spring mounting holes 311 are provided at both ends of the base 31, a rotating shaft 312 is provided in the middle of the base 31, the first buckle 32 and the second buckle 33 rotate around the rotating shaft 312, and a spring 34 arranged in the spring mounting hole 311 provides a locking force for the engaging protrusion 23.

[0051] In other words, Figure 4 As shown, the groove portion is primarily composed of a base 31, a first retaining ring 32, a second retaining ring 33, and a spring 34. The base 31 has spring mounting holes 311 at both ends, and a rotation axis 312 in the middle. The first retaining ring 32 and the second retaining ring 33 can each rotate about the rotation axis 312. A spring 34 is placed in each of the spring mounting holes 311. One end of the spring 34 is restrained by the spring mounting hole 311, while the other end abuts against the edge of the first retaining ring 32 or the second retaining ring 33. As a result, the first retaining ring 32 and the second retaining ring 33 form a groove that engages the protruding buckle 23. The spring 34 provides preload force for the engaging protruding buckle 23.

[0052] Therefore, the groove portion 30 of the display quick-release device of the present invention forms a groove that can engage with the convex buckle 23 through the first ring buckle 32 and the second ring mouth 33, so that the groove portion 30 can engage and fix the display module 20, and the spring 34 provides a pre-tightening force for the engaging convex buckle 23, further strengthening the engaging force, so that the display module 20 is fixed more firmly.

[0053] According to one embodiment of the present invention, the display module 20 includes a conical protrusion 24 , which is fixed to the back of the display 21 ; a positioning hole 12 is provided near the replacement port 10 at a position corresponding to the conical protrusion 24 .

[0054] In other words, Figure 3 As shown, the display module 20 further includes a conical convex buckle 24, which is fixed to the back of the display 21. The conical convex buckle 24 can be integrally formed with the back of the display, or can be mechanically fixed or adhesively fixed to the display 21. Figure 1 As shown, a positioning hole 12 is provided at a position corresponding to the conical protrusion 24 near the replacement port 10. The conical protrusion 24 is interference fit with the positioning hole 12. When the display module 20 is fixed to the replacement port 10, the positioning hole 12 has a pre-tightening effect on the conical protrusion 24, which can further limit the relative movement of the display module 20 to the replacement port 10.

[0055] According to one embodiment of the present invention, the display module 20 also includes: a bracket 25, which connects the U-shaped support arm 22 and the display 21; a first decorative panel 26, which is fixed on one side of the U-shaped support arm 22; and a second decorative panel 27, which is fixed on the other side of the U-shaped support arm 22.

[0056] In other words, Figure 2 As shown, the display module 20 also includes a bracket 25, a first decorative panel 26, and a second decorative panel 27. The bracket 25 is secured to the back of the display with screws. The U-shaped support arm 22 has strip holes formed in it and is secured to the bracket 25 with screws. These holes allow the distance between the U-shaped support arm 22 and the display 21 to be adjusted to accommodate inspection robots of different sizes.

[0057] A first decorative panel 26 is fixed to one side of the U-shaped support arm 22, and a second decorative panel 27 is fixed to the other side of the U-shaped support arm 22. When the display module 20 is fixed to the robot, the first and second decorative panels 26 and 27 block external vision, preventing the internal structure of the replacement port 10 and the U-shaped support arm 22 from being exposed and affecting the overall aesthetics.

[0058] According to an embodiment of the present invention, the first decorative plate 26 and the second decorative plate 27 are connected to the U-shaped support arm 22 respectively by screws, and decorative rubber plugs 28 are provided at the screw holes.

[0059] In other words, Figure 2 As shown, threaded holes are provided at both ends of the U-shaped support arm 22, and the first decorative plate 26 and the second decorative plate 27 are connected to the U-shaped support arm 22 by screws respectively. In order to avoid seeing the screw heads, decorative plugs 28 are added in the screw vacancies to further beautify the appearance of the display module 20.

[0060] According to an embodiment of the present invention, the number of the grooves 30 and the number of the protrusions 23 are both four.

[0061] Furthermore, the number of the conical protrusions 24 and the number of the positioning holes 12 are both two, and the two positioning holes 12 are arranged at opposite ends of the replacement port 10 .

[0062] That is to say, if Figure 1 As shown, four grooves are spaced apart and arranged on the two upright posts 11, and four protrusions 23 are provided at the bottom of the corresponding U-shaped support arm 22. The four-point engagement further strengthens the bite force on the display module 20. The number of the conical protrusions 24 and the positioning holes 12 can also be set to multiple, preferably two. The two positioning holes 12 are set at the opposite ends of the replacement port 10, which can be the upper and lower ends or the left and right ends, such as Figure 6 As shown, the pre-tightening force of the two positioning holes 12 on the conical protrusions 24 further increases the stability of the display module 20 and prevents the display module 20 from becoming loose due to vibration during the movement of the inspection robot.

[0063] According to an embodiment of the present invention, the display quick-release device further includes a decorative panel 40 . The decorative panel 40 is interchangeable with the display module 20 and is fixed to the replacement port 10 .

[0064] When the display module 20 is no longer needed, after being disassembled from the robot, the replacement port 10 of the robot needs to be blocked to avoid affecting the appearance. The display quick-release device of the present invention also includes a decorative panel 40, which is interchangeable with the display module 20 and fixed to the replacement port 10.

[0065] According to one embodiment of the present invention, one side of the replacement port 10 is partially concave to form an armrest position 13, a groove 14 is provided around the replacement port 10, and an iron sheet 15 is provided in the groove 14; a magnet 41 is provided on the inner surface of the decorative panel 40 relative to the iron sheet 15.

[0066] In other words, Figure 9 As shown, if the decorative panel 40 is fixed with screws, it is not only inconvenient but also affects the appearance. The display quick-release device of the present invention has a partial concave portion on one side of the replacement port 10 to form an armrest 13, which is convenient for fingers to insert. At the same time, the replacement port 10 is provided with a groove 14 formed along the edge of the replacement port. A number of iron sheets 15 are provided in the groove 14. The iron sheets 15 can be fixed with screws or fixed to the groove 14 using double-sided tape. A magnet 41 is provided on the inner surface of the decorative panel 40 relative to the iron sheet 15. The magnet 41 is adhered to the inner surface of the decorative panel 40, or a mechanical fixation method can be used. When installing the decorative panel 40, the decorative panel 40 equipped with the magnet 41 is placed close to the replacement port 10. The decorative panel 40 is fixed to the replacement port 10 by the magnetic force of the iron sheet 15 and the magnet 41. When the decorative panel 40 needs to be removed, the decorative panel 40 can be removed by prying it with the fingers through the armrest 13. It is quick and convenient, while maintaining a neat and beautiful appearance.

[0067] Therefore, the use process of the display quick release device of the present invention is as follows:
