Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a quick-disassembly structure of a power protection panel of a quadruped robot. Background Art

[0002] Quadruped robots are legged robots. Compared with common wheeled robots, they have good adaptability to stairs, slopes and rugged surfaces and are widely used in various fields. In many fields, robots are required to have a long working time and endurance, such as security inspection, exploration and rescue, so the power supply or battery installed on the quadruped robot needs to be replaced or maintained regularly. However, the following problems exist in the process of staff using batteries:

[0003] Generally, the power supply is placed in the battery compartment, which is closed by a protective panel or other outer shell and fixed by multiple screws. When replacing or maintaining the power supply, you need to manually use a screwdriver to unscrew multiple screws before you can remove the panel. The disassembly process is cumbersome and inconvenient, resulting in low efficiency. In addition, since the screw structure is small, it is easy to lose it if it falls accidentally, which requires time and effort to find or replace it.

[0004] In order to solve the above problems, a quick-disassembly structure is needed that can quickly disassemble or install a panel or a housing on a power supply, thereby simplifying the disassembly and installation work and improving the efficiency of the staff. Utility Model Content

[0005] The purpose of the utility model is to provide a quick-release structure for a power protection panel of a quadruped robot, which can be directly operated to dismantle or install the power protection panel and can avoid the loss of quick-release screws used for docking.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A quick-release structure for a power protection panel of a quadruped robot comprises a frame and an outer cover, the outer cover and the frame are separable, the frame is provided with a threaded groove, the outer cover is provided with a mounting hole and a quick-release screw, the quick-release screw passes through the mounting hole and is detachably connected to the threaded groove, the outer end of the quick-release screw is provided with a gripping portion for finger gripping, and the quick-release screw can be controlled to connect / disconnect between the threaded grooves by rotating the gripping portion.

[0008] Compared with the prior art, the quick-disassembly structure of the power protection panel of the quadruped robot using the above technical solution has the following beneficial effects:

[0009] The quick-release structure of the power protection panel of the quadruped robot of the utility model can directly control the movement of the quick-release screw through the grasping part to control the connection or separation of the quick-release screw and the thread groove, without using a screwdriver or other disassembly tools, let alone easy-to-lose parts such as screws, so that the outer cover (power protection panel) and the frame can be quickly connected or disassembled to expose the battery compartment for easy replacement or maintenance of the battery, and the utility model has the characteristics of being easy to use; the time required for disassembly and installation of the outer cover is effectively reduced, and the work efficiency of the staff is improved.

[0010] Preferably, the quick-release screw has a threaded rod, and the mounting groove is provided with an internal thread. The threaded rod of the quick-release screw passes through the mounting hole and docks with the threaded groove. The threaded rod is rotated by the gripping part to connect / disconnect the fixing member with the threaded groove between the grooves. The gripping part is directly rotated by hand to drive the threaded rod to be threadedly connected with or detached from the threaded groove, which effectively simplifies the docking operation of the quick-release screw and facilitates the direct operation of the staff to further improve the work efficiency.

[0011] Preferably, a limiting ring is provided at the outer end of the mounting hole, and the threaded rod is connected to the gripping portion by a connecting rod, and the connecting rod can pass through the middle of the limiting ring, while the threaded rod cannot pass through the middle of the limiting ring. After the threaded rod and the thread groove are released from the docking state, the limiting ring is used to limit the moving path of the threaded rod to prevent the threaded rod from directly detaching from the mounting hole. After the outer cover is separated from the frame, the quick-release screw is still located on the outer cover, thereby avoiding the problem of the quick-release screw being lost and facilitating subsequent installation.

[0012] Preferably, the inner diameter of the mounting hole, the outer diameter of the threaded rod, the inner diameter of the limiting ring, and the outer diameter of the connecting rod are successively reduced. Restricted by the inner diameter of the mounting hole and the inner diameter of the limiting ring, both the threaded rod and the connecting rod can move in the mounting hole, but the connecting rod can be displaced in the limiting ring to meet the operation of controlling the movement of the threaded rod; and by limiting the outer diameter, that is, the outer diameter of the threaded rod exceeds the inner diameter of the limiting ring, the limiting ring can limit the movement path of the threaded rod.

[0013] Preferably, the outer surface of the outer cover is further provided with a countersunk groove, and the mounting hole is located at the bottom of the countersunk groove. When the outer cover and the rack are docked, the countersunk groove is recessed in the outer cover, so that most of the quick-release screws used for docking are located in the recessed structure, so as to minimize the protrusion of the fixing part from the outer cover and reduce the risk of the protruding fixing part colliding with foreign objects.

[0014] Preferably, the gripping portion is located in the countersunk groove, and the outer end of the gripping portion does not extend beyond the end surface where the opening of the countersunk groove is located. When the outer cover and the frame are docked, the gripping portion of the quick-release screw does not protrude from the outer cover, which can effectively avoid the problem of the gripping portion colliding with other objects when the robot is moving.

[0015] Preferably, the outer cover surface is provided with an insertion rod, and the frame is provided with a slot, and when the insertion rod is inserted into the slot, the mounting hole is aligned with the threaded groove. The insertion rod and the slot are butt-jointed and fixed to increase the stability of the connection between the outer cover and the frame; and because the slot position on the frame is fixed, when the outer cover is installed, the slot effectively guides the installation direction of the outer cover, and the threaded groove will automatically align with the mounting hole, so that the outer cover can be quickly installed without much consideration, and it has the characteristics of being easy to use.

[0016] Preferably, the outer cover is rectangular, the insertion rod is located at the edge of the outer cover, the threaded groove is located in the middle of the outer cover, and the number of the slot and the insertion rod are both two, and the number of the mounting hole and the threaded groove are both two. By using the insertion rod structure protruding from the edge of the outer cover, the side of the outer cover provided with the insertion rod can be effectively fixed to the frame, and the middle of the outer cover can be fixed to the frame by quick release screws, so as to achieve the fixing effect of multiple different points on the outer cover and the frame, and further increase the stability of the connection state.

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 The quick-release structure of the quadruped robot power protection panel shown includes a frame 0 and an outer cover 1.

[0026] The outer cover 1 and the frame 0 are two separable independent components. The frame 0 is provided with a threaded groove 2, and the outer cover 1 is provided with a mounting hole 3 and a quick-release screw 4. The quick-release screw 4 passes through the mounting hole 3 and is detachably connected to the threaded groove 2.

[0027] There are many ways to connect the quick-release screw 4 to the thread groove 2, such as insert-type clamping or threaded connection. In this embodiment, a threaded connection that is convenient and quick to use is adopted. That is, an internal thread is provided in the thread groove 2, and the quick-release screw 4 is divided into a threaded rod 41, a connecting rod 42 and a gripping portion 40 for finger gripping. The threaded rod 41 and the gripping portion 40 are connected by the connecting rod 42. The gripping portion 40 is provided at the outer end of the connecting rod 42. The threaded rod 41 of the quick-release screw 4 passes through the mounting hole 3 and is threadedly connected to the inner wall of the thread groove 2.

[0028] In order to avoid the loss of the quick-release screw 4 and facilitate subsequent use, a limiting ring 5 is provided at the outer end of the mounting hole 3, and the inner diameter of the mounting hole 3, the outer diameter of the threaded rod 41, the inner diameter of the limiting ring 5, and the outer diameter of the connecting rod 42 are successively reduced, and the width of the gripping portion 40 also exceeds the caliber of the limiting ring 5.

[0029] Both the threaded rod 41 and the connecting rod 42 can move in the mounting hole 3 , but the connecting rod 42 can pass through the middle of the limiting ring 5 , while the threaded rod 41 cannot pass through the middle of the limiting ring 5 .

[0030] In order to prevent the gripping portion 40 from protruding from the outer cover 1, a countersunk groove 6 is further provided on the outer surface of the outer cover 1, the mounting hole 3 is located at the bottom of the countersunk groove 6, the gripping portion 40 is located in the countersunk groove 6, and the outer end of the gripping portion 40 does not exceed the end surface of the opening of the countersunk groove 6.

[0031] The outer cover 1 has an insertion rod 7 on its surface, and the frame 0 has a slot 8. When the insertion rod 7 is inserted into the slot 8, the mounting hole 3 is aligned with the threaded groove 2, so that the quick-release screws 4 can be directly connected.

[0032] In order to increase the connection stability between the outer cover 1 and the frame 0, the outer cover 1 can adopt a rectangular structure or other structure with smooth edges. In the present embodiment, the number of slots 8 and insertion rods 7 are both two, the number of mounting holes 3 and threaded grooves 2 are both two, and the two insertion rods 7 are respectively located on the upper side of the outer cover 1 near the edge of the end, and the two threaded grooves 2 are located in the middle of the outer cover 1.

[0033] The following is the usage of this embodiment:

[0034] Under normal conditions, the outer cover 1 is fixed on the rack 0. If the power supply / battery needs to be replaced or maintained, the fingers pinch the gripping portion 40 and rotate it, and the threaded rod 41 is driven to rotate in the thread groove 2 through the connecting rod 42. The threaded rod 41 gradually withdraws from the thread groove 2, and the connecting rod 42 moves in the middle of the limit rod until the threaded rod 41 is blocked by the limit ring 5. At this time, the threaded rod 41 is separated from the thread groove 2, and the quick-release screw 4 cannot move as a whole. Then the staff holds the left and right sides of the outer cover 1 with both hands and pulls downward, so that the insertion rod 7 is separated from the slot 8 on the rack 0, and the outer cover 1 and the rack 0 are separated. The power supply compartment / battery compartment is exposed to the outside world and can be replaced or maintained.

[0035] After the outer cover 1 is removed, due to the blocking effect of the limit ring 5 on the threaded rod 41 and the large structure of the gripping part 40, the outer cover 1 can move freely and the fixing part 4 will not be separated from the outer cover 1. After replacement or maintenance is completed, the insertion rod 7 on the edge of the outer cover 1 is aligned with the slot 8 of the frame 0 and inserted into it. At this time, the mounting hole 3 is aligned with the thread groove 2, and the gripping part 40 is rotated in the reverse direction, so that the threaded rod 41 and the thread groove 2 can be threadedly connected, and the outer cover 1 and the frame 0 are re-fixed.

[0036] The above is a preferred embodiment of the present invention. A person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements shall also be regarded as within the protection scope of the present invention.
