Description

Technical Field

[0001] The present invention relates to the technical field of underwater submersibles, and in particular to a quick-detachable cabin for an underwater submersible. Background Art

[0002] At present, underwater submersibles on the market are powered by their own batteries, so the working time of the robot is closely related to the battery capacity. Under the same output power, the battery capacity is small and the machine working time is short. If you want the machine to work longer, you need to increase the battery capacity, but the battery volume and weight will increase. In order to ensure the buoyancy of the entire machine in the water, you need to increase the volume of the sealed cabin or increase the buoyancy material to offset the increased battery weight, so the machine will become bulky and inconvenient to carry. On the other hand, when traveling, especially by plane, the Civil Aviation Administration has very strict restrictions on the lithium battery capacity of electronic equipment, which limits the promotion of products. In summary, the battery capacity of existing underwater submersibles is controlled within 100Wh. In order to ensure its working time, it will be equipped with a backup power supply so that it can be quickly switched when it is running out of power.

[0003] In the prior art, the battery and the working parts are usually enclosed in the same sealed cabin, which is not easy to disassemble, so the underwater submersible cannot be used continuously after the battery is exhausted, and a charging time must be interval between two uses. If the battery is frequently disassembled and assembled, it is easy to cause the sealing of the cabin parts to fail, resulting in damage to the equipment. Summary of the invention

Once the hands are released, the first buckle 32 will bounce up under the action of the spring 31 and will be snapped into the slot 4 again.

[0045] Example 3

[0046] In order to prevent the first buckle 32 from rebounding under the action of the spring 31, another structure of the battery quick release buckle assembly 3 is disclosed in this embodiment. Figure 5 As shown, the battery quick-release buckle assembly 3 is composed of a spring 31 , a first buckle 32 , a locking member 35 , a buckle fixing seat 33 and a connecting column 323 .

[0047] like Figure 6 As shown, a buckle protrusion 321 is provided at the end of the first buckle 32, and a connecting plate 322 is extended outward from the other end of the buckle protrusion 321. A clearance hole 324 is opened on the connecting plate 322, and the clearance hole 324 is located directly below the connecting column 323. A third clearance groove 329 is opened radially along the clearance hole 324. The third clearance groove 329 is 1 / 4 ring-shaped and is provided with four. The outer side of the third clearance groove 329 is the first clearance groove 325, which is semi-ring-shaped and relatively arranged on both sides of the clearance hole 324.

[0048] like Figure 7 As shown, the buckle fixing seat 33 is a hollow cavity with an opening at the bottom and a buckle clearance groove 331 is opened on one side, and the buckle clearance groove 331 is adapted to the connecting plate 322; a fixing column 332 is downwardly arranged in the middle of the top of the buckle fixing seat 33, and the fixing column 332 is inserted into the clearance hole 324; a first positioning protrusion 334 extends downwardly from the inner side wall of the top of the buckle fixing seat 33, and the first positioning protrusion 334 is inserted into the first clearance groove 325; the buckle fixing seat 33 is opened at the top Two give-way grooves 333, the second give-way groove 333 is semi-annular and is relatively arranged between the fixing column 332 and the first positioning protrusion 334, the connecting column 323 is inserted into the second give-way groove 333, and the inner diameter of the spring 31 is adapted to the outer wall of the first positioning protrusion 334; a second positioning protrusion 335 is arranged between the first positioning protrusion 334 and the second give-way groove 333, and the number of the second positioning protrusion 335 is consistent with that of the third give-way grooves 329 and they are respectively inserted into the third give-way grooves 329.

[0049] A locking member 35 is disposed above the connecting plate 322 , a connecting column 323 is disposed above the locking member 35 , an outer wall of the connecting column 323 protrudes outward to form a protrusion 328 , and a guide rail 336 matched with the protrusion 328 is disposed on the inner wall of the second positioning protrusion 335 .

[0050] like Figure 8As shown, the locking member 35 is composed of a fixing ring 351 and locking teeth 352. The cross-section of the locking teeth 352 is a right-angled trapezoid and is evenly distributed on the fixing ring 351 along the radial direction; the bottom of the connecting column 323 is continuously provided with serrated teeth 327, the teeth 327 press on the locking teeth 352, and the locking teeth 352 are clamped in the gap between adjacent second positioning protrusions 335; the bottom of the second positioning protrusion 335 has two connected slopes 337, and the slope 337 is consistent with the inclination direction of the inclined surface of the locking teeth 352.

[0051] During assembly, the locking member 35 is placed on the connecting plate 322 with the locking teeth 352 facing upwards, the teeth 327 of the connecting column 323 are pressed against the locking teeth 352, and then the buckle fixing seat 33 is put down from the connecting column 323, so that the protrusion 328 is in the guide rail 336 and the locking teeth 352 are in the gap formed by the adjacent second positioning protrusion 335, and then the spring 31 is clamped on the outer wall of the first positioning protrusion 334, and the assembled battery quick release buckle assembly 3 is placed in the first positioning groove 11, one end of the spring 31 is located in the second positioning groove 13, and the other end is pressed against the bottom of the connecting plate 322. Finally, the buckle fixing seat 33 is fixed to the positioning countersunk hole 12 through the fixing column 332 using a fastener. After assembly, the pressing key cap 34 is assembled on the top of the connecting column 323 until the second buckle is clamped in the limiting groove 326.

[0052] When installing the battery, first align the socket assembly 6 of the battery compartment shell 2 with the plug assembly 5 of the control compartment shell 1, and push the battery compartment shell 2 toward the control compartment shell 1 until the first clip 32 is engaged in the slot 4. The first clip 32 will be clamped in the slot 4 under the elastic force of the spring 31, and the clip will not fall out without external force, thereby ensuring the reliability of assembly.

[0053] When the battery needs to be replaced, the push button cap 34 of the battery quick release buckle assembly 3 is pressed, and the connecting column 323 presses the locking member 35 downward until the locking member 35 is disengaged from the gap formed by the adjacent second positioning protrusion 335. Under the action of the tooth 327, the locking tooth 352 will move relative to the tooth 327, causing the locking member 35 to rotate, and the inclined surface of the locking tooth 352 will move relative to the slope 337. The locking tooth 352 moves downward along one of the slopes 337 until the locking tooth 352 moves to the place where the two slopes 337 are connected. The locking tooth 352 moves upward under the action of the spring 31 and is clamped at the turning point where the two slopes 337 are connected. At this time, the first buckle 32 is disengaged from the slot 4 and the position is locked, and it no longer moves upward. At this time, the battery compartment component can be removed, and single-handed operation can be achieved.

[0054] The key cap 34 is pressed again, and the locking member 35 continues to rotate under the action of the tooth 327, and the locking tooth 352 continues to move along another slope 337 until it escapes from the bottom of the slope 337 and enters the gap formed by the adjacent second positioning protrusion 335 again, and continues to move upward under the action of the spring 31 until the first buckle 32 is engaged in the slot 4.

[0055] To facilitate the positioning and assembly between the cabins, a first positioning plane is concavely arranged on the outer wall of the control cabin shell 1, and a second positioning plane is convexly arranged on the battery cabin shell 2. During assembly, the first positioning plane is aligned with the second positioning plane and then moves relative to each other to complete the assembly.

[0056] Example 4

[0057] To further optimize the technical solution in Example 1, the plug assembly 5 described in this embodiment is composed of a plug socket 51 and a PIN pin socket. One end of the plug socket 51 is fixed on the end face of the control cabin shell 1, and the other end is concave inward to form a groove. A PIN pin socket is fixed at the bottom of the groove. An L-shaped exhaust through hole 52 is arranged on the side wall of the plug socket 51; one end of the exhaust through hole 52 is located at the bottom of the outer wall and a one-way pressure reducing valve 7 is arranged inside, and the other end is located at the bottom of the groove. Correspondingly, the socket assembly 6 is composed of a socket and a PIN pin plug. Fig. 9 As shown, the plug seat 51 is plugged into the socket, and the PIN pin plug is plugged into the PIN pin socket, so as to realize the assembly of the plug assembly 5 and the socket assembly 6, and realize the power supply of the battery compartment component to the control compartment component.

[0058] In order to meet the watertight requirements, two O-rings are arranged on the outer wall of the plug seat 51 to achieve radial sealing between the plug seat 51 and the socket. During assembly, after the O-ring enters the inner wall of the socket to form a seal, it is extremely difficult for the air inside the sealed cavity to be discharged from the gap between the two. As the two cabin shells continue to be assembled, a small amount of air in the plug seat 51 and the socket is squeezed, and the internal pressure gradually increases. When the pressure is too high, in order to prevent the battery compartment components from being ejected and causing poor sealing, resulting in water ingress, an L-shaped exhaust hole 52 is arranged on the side wall of the plug seat 51. The squeezed air enters the exhaust hole 52 from one end of the bottom of the groove of the plug seat 51 and is discharged from the other end on its side wall. In addition, in order to prevent water and air from entering from the exhaust hole 52, a one-way pressure reducing valve 7 is arranged at the exhaust hole 52 located on the side wall section of the plug seat 51.

[0059] Although the present invention has been described herein with reference to a plurality of illustrative embodiments of the present invention, it will be appreciated that those skilled in the art can devise many other modifications and embodiments which will fall within the scope disclosed herein. Other uses will also be apparent to those skilled in the art.
