Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment, and specifically relates to an underwater device with a detachable battery compartment. Background Technology

[0002] With the continuous development of underwater operations, marine resource exploration, underwater scientific research, and underwater recreation, the application of various underwater equipment is becoming increasingly widespread. These underwater devices typically rely on batteries as a power source to ensure their normal operation in the underwater environment.

[0003] However, traditional underwater equipment often has some design limitations. In most cases, the battery compartment and the mainboard are integrated into the same cavity. While this design simplifies the structure and assembly process to some extent, it has revealed many problems in actual use.

[0004] On the one hand, since the battery and the device's motherboard are located in the same cavity, a malfunction or damage to one component can easily affect other components. For example, if the battery leaks, it may corrode and damage the electronic components on the device's motherboard; conversely, if the device's motherboard malfunctions, replacing it may also adversely affect the battery and its connecting circuits, and could even lead to safety accidents due to improper operation.

[0005] On the other hand, in complex underwater operating environments, such as deep-sea exploration and long-term underwater monitoring, the reliability and stability of equipment are crucial. Traditional integrated designs have low fault tolerance in harsh environments. If a critical component fails, the entire device may fail, requiring complex repairs or replacements. This not only affects the smooth progress of the mission but may also lead to significant data loss and economic losses.

[0006] Furthermore, for some underwater equipment that requires continuous operation for extended periods, battery endurance is a pressing issue. In traditional designs, because the battery and motherboard are housed in the same cavity, battery capacity and ease of replacement are limited, making it difficult to meet the needs of long-term equipment operation.

[0007] Therefore, how to design a more reasonable, reliable, and easy-to-maintain and replace underwater equipment structure has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0062] See Figure 1-11 A detachable battery compartment underwater device includes: a first connecting seat 1, a second connecting seat 2, a battery compartment mechanism 3, a functional device 4, and a locking mechanism 8.

[0063] The first connecting seat 1 is fixed on the battery compartment mechanism 3, and the first connecting seat 1 is electrically connected to the battery compartment mechanism 3;

[0064] The second connecting seat 2 is fixed on the functional device 4, and the second connecting seat 2 is electrically connected to the functional device 4;

[0065] The battery compartment mechanism 3 is detachably mounted on the outside of the functional device 4 via the locking mechanism 8, and the first connecting seat 1 and the second connecting seat 2 are detachably plugged in to provide waterproofing while maintaining electrical connection.

[0066] In this embodiment, the first connecting seat 1 includes a first connecting member 11 and an insulated first water barrier 12. The first connecting member 11 is fixedly disposed on the battery compartment mechanism 3. One end of the first connecting member 11 protrudes from the outside of the battery compartment mechanism 3 to form a first connecting end 111, and the other end of the first connecting member 11 extends into the battery compartment mechanism 3 to form a first device end 112 electrically connected to the battery compartment mechanism 3. The first water barrier 12 is fixedly disposed on the outside of the battery compartment mechanism 3 and surrounds the first connecting end 111, covering the outside of the first connecting end 111.

[0067] The second connecting seat 2 includes a second connecting member 21 and an insulated second water barrier 22. The second connecting member 21 is fixedly disposed on the functional device 4. One end of the second connecting member 21 protrudes from the outside of the functional device 4 to form a second connecting end 211, and the other end of the second connecting member 21 extends into the functional device 4 to form a second device end 212 that is electrically connected to the functional device 4. The second water barrier 22 is fixedly disposed on the outside of the functional device 4 and surrounds the second connecting end 211 to cover the outside of the second connecting end 211.

[0068] When the functional device 4 and the battery compartment mechanism 3 are connected, the physical connection is completed through the locking mechanism 8. Simultaneously, the first water-proof barrier 12 of the first connecting seat 1 is detachably fitted onto the outside of the second water-proof barrier 22 of the second connecting seat 2, and the first connecting end 111 and the second connecting end 211 are detachably electrically connected. After the electrical connection is completed through the first connecting seat 1 and the second connecting seat 2, the battery compartment mechanism 3 can sequentially supply power to the functional device 4 through the first device end 112, the first connecting end 111, the second connecting end 211, and the second device end 212. During this process, the first water-proof barrier 12 and the second water-proof barrier 22 work together to surround and shield the outside of the electrically connected first connecting end 111 and second connecting end 211, forming a double waterproof structure. At the same time, the cooperation of the first water-proof barrier 12 and the second water-proof barrier 22 also improves the structural stability when the battery compartment mechanism 3 and the functional device 4 are connected. It should be emphasized that, in other implementations, the second water-proof barrier 22 of the second connecting seat 2 can be detachably sleeved on the outside of the first water-proof barrier 12 of the first connecting seat 1 to complete the insertion between the second connecting seat 2 and the first connecting seat 1.

[0069] It is worth noting that functional device 4 can be various devices that require electrical energy to perform their functions; see [link to relevant documentation]. Figure 7-10 Functional device 4 can be a flash, video light, camera housing, monitor housing, etc.

[0070] In this embodiment, the underwater device also includes a first waterproof ring 5, which is fitted on the outside of the second water barrier 22, and the inside of the first water barrier 12 abuts against the first waterproof ring 5.

[0071] In this embodiment, after the first connecting seat 1 and the second connecting seat 2 are connected, the end of the first water barrier 12 abuts against the outside of the functional device 4 to further prevent external liquid from entering the connection between the first connecting end 111 and the second connecting end 211.

[0072] In this embodiment, a first waterproof groove 221 is provided around the outer side of the second waterproof barrier 22, and a first waterproof ring 5 is fitted inside the first waterproof groove 221 and protrudes from the outer side of the second waterproof barrier 22, so as to ensure the stability of the first waterproof ring 5 on the second waterproof barrier 22 and further improve the waterproof performance at this point.

[0073] In this embodiment, there are multiple first waterproof rings 5 ​​and multiple first waterproof grooves 221, with the multiple first waterproof rings 5 ​​respectively fitted onto the multiple first waterproof grooves 221 on the outside of the second connector 21.

[0074] In this embodiment, the first connecting seat 1 further includes a first insulating sleeve 6. The battery compartment mechanism 3 is provided with a first mounting hole 31. The first connecting member 11 is disposed in the first mounting hole 31. The inner side of the first insulating sleeve 6 is sleeved and attached to the first connecting member 11, and the outer side of the first insulating sleeve 6 is attached to the side of the first mounting hole 31. Specifically, the first insulating sleeve 6 is made of POM plastic.

[0075] In this embodiment, a second waterproof groove 61 is provided on the outer side of the first insulating sleeve 6, and a second waterproof ring 62 is fitted inside the second waterproof groove 61. The second waterproof ring 62 abuts against the side of the first mounting hole 31. Specifically, there can be one or more second waterproof grooves 61 and second waterproof rings 62.

[0076] In this embodiment, a third waterproof ring 63 is fitted onto the first connector 11, and the third waterproof ring 63 abuts against the inner side of the first insulating sleeve 6. Specifically, the number of the third waterproof ring 63 can be one or more.

[0077] In this embodiment, the first connecting member 11 is movably connected to the first insulating sleeve 6. A spring-loaded cavity 64 is provided at one end of the first insulating sleeve 6 near the first connecting end 111. A retaining ring 113 is fixed to the outside of the first connecting end 111. A first spring 65 is also provided inside the spring-loaded cavity 64, sleeved on the first connecting end 111, with both ends of the first spring 65 abutting or connecting to the retaining ring 113 and the first insulating sleeve 6, respectively. Specifically, a movable piece 66 is also movably disposed inside the spring-loaded cavity 64, sleeved on the first connecting end 111. Both ends of the first spring 65 abut or connect to the retaining ring 113 and the movable piece 66, respectively. The first spring 65 pushes the movable piece 66 against the bottom surface of the spring-loaded cavity 64 of the first insulating sleeve 6. When the first connecting end 111 and the second connecting end 211 are connected, the second connecting end 211 can resist and push the first connecting end 111 of the first connecting member 11. At this time, the first connecting end 111 drives the retaining ring 113 to compress the first spring 65 and retracts within the first insulating sleeve 6.

[0078] In this embodiment, the battery compartment mechanism 3 is provided with a trigger 3311 for electrically connecting the first device end 112 to the battery compartment mechanism 3. The movement of the first connector 11 on the first insulating sleeve 6 includes a trigger state in which the first device end 112 is pushed back to abut against the trigger 3311 when the second connector end 211 abuts against the first connector end 111, and a power-off state in which the first device end 112 is separated from the trigger 3311 under the rebound of the first spring 65 when the second connector end 211 is separated from the first connector end 111.

[0079] Specifically, when the first connecting seat 1 is connected to the second connecting seat 2, the first connecting end 111 will be pushed back under the resistance of the second connecting end 211. At this time, the first spring 65 is compressed, and the first device end 112 is resisted by the trigger 3311. The first connecting end 11 is in the triggered state, and the battery compartment mechanism 3 is electrically connected to the functional device through the trigger 3311, the first connecting end 11, and the second connecting end 21. When the first connecting seat 1 is separated from the second connecting seat 2, the first spring 65 rebounds, causing the first connecting end 11 to reset. The first device end 112 is separated from the trigger 3311, and the first connecting end 11 is in the de-energized state. The first device end 112 is disconnected from the battery compartment mechanism 3. At this time, even if the first connecting end of the first connecting seat directly touches the liquid, it will not cause a short circuit in the battery compartment mechanism, making it safer and more reliable.

[0080] In this embodiment, the second connector 2 further includes a second insulating sleeve 7. The functional device 4 is provided with a second mounting hole 41. The second connector 21 is disposed in the second mounting hole 41. The inner side of the second insulating sleeve 7 is fitted and attached to the second connector 21, and the outer side of the second insulating sleeve 7 is attached to the side of the second mounting hole 41. Specifically, the second insulating sleeve 7 is made of POM plastic.

[0081] In this embodiment, a third waterproof groove 71 is provided on the outer side of the second insulating sleeve 7, and a fourth waterproof ring 72 is fitted inside the third waterproof groove 71. The fourth waterproof ring 72 abuts against the side of the second mounting hole 41. Specifically, the number of the third waterproof groove 71 and the fourth waterproof ring 72 can be one or more.

[0082] In this embodiment, a fourth waterproof groove 213 is fitted onto the second connector 21, and a fifth waterproof ring 73 is fitted inside the fourth waterproof groove 213, with the fifth waterproof ring 73 abutting against the inner side of the second insulating sleeve 7. Specifically, the number of the fourth waterproof groove 213 and the fifth waterproof ring 73 can be one or more.

[0083] In this embodiment, there are multiple first connectors 11 and multiple second connectors 21, and the multiple first connectors 11 are detachably electrically connected to the multiple second connectors 21 respectively.

[0084] In this embodiment, the first waterproof ring 5, the second waterproof ring 62, the third waterproof ring 63, the fourth waterproof ring 72, and the fifth waterproof ring 73 are all O-shaped silicone rings.

[0085] In this embodiment, the first connecting seat 1 is bent and fixed at the lower end of the battery compartment mechanism 3. The bending angle of the first connecting seat 1 can be ninety degrees, and it is parallel to the locking mechanism 8 after bending. The upper end or middle part of the battery compartment mechanism 3 is detachably set on the outside of the functional device 4 through the locking mechanism.

[0086] In this embodiment, the battery compartment mechanism 3 includes a battery compartment body 32 and a connecting seat 33. A battery assembly 321 is disposed inside the battery compartment body 32. A contact surface 322 is formed at the lower end of the battery compartment body 32, and a battery contact terminal 323 electrically connected to the battery assembly 321 is disposed at the contact surface 322.

[0087] A power receiving groove 331 is provided on the connecting body 33. The first connector 11 and the first water barrier 12 are both fixedly installed on the connecting body 33. The first connecting end 111 protrudes from the outside of the connecting body 33, and the first equipment end 112 extends into the power receiving groove 331.

[0088] The connecting base 33 is provided with a power inlet 332 that communicates with the power inlet groove 331. The connecting base 33 is detachably connected to the lower end of the battery compartment mechanism 3 via a screw structure. The power inlet 322 abuts against the power inlet 332 to close the power inlet 332. The first device end 112 is electrically connected to the battery power inlet 323 via a trigger 3311. Specifically, the trigger 3311 is located in the wiring groove and is electrically connected to the battery power inlet 323. When the first connecting member 11 is in the triggered state, the first device end 112 is electrically connected to the battery power inlet 323 via the trigger 3311. When the first connecting member 11 is in the de-energized state, the first device end 112 is separated from the trigger 3311, thereby disconnecting the power connection from the battery power inlet 323.

[0089] It should be emphasized that the battery assembly 321 specifically includes a battery, circuit board and other structures, and can be electrically connected to the first device end 112 through the battery terminal 323, so that the first connector 1 can be used as a port to provide power to the functional device 4; and based on the structural design between the battery compartment 32 and the connector 33, while ensuring that water does not easily enter the power connection slot 331, the first connector of a different type or size can be replaced by disassembling and replacing the connector 33.

[0091] In this embodiment, the locking mechanism 8 includes a first locking member 81 and a second locking member 82. The first locking member 81 is fixedly disposed on the outside of the functional device 4, and a locking position for locking the battery compartment mechanism 3 is formed between the second locking member 82 and the first locking member 81.

[0092] In this embodiment, one end of the second locking member 82 is hinged to one end of the first locking member 81, and the other end of the second locking member 82 is detachably connected to the other end of the first locking member 81. The locking position is a locking cavity 83 for surrounding the battery compartment mechanism 3.

[0093] The locking mechanism 8 locks the battery compartment mechanism 3 as follows: First, the other end of the first locking member 81 is separated from the second locking member 82. Then, one end of the second locking member 82 is rotated around one end of the first locking member 81 to open the locking cavity 83. Next, the battery compartment mechanism 3 is placed in the locking cavity 83 between the first locking member 81 and the second locking member 82, and one end of the second locking member 82 is rotated in the opposite direction around one end of the first locking member 81 so that the other end of the first locking member 81 comes closer to the second locking member 82. Finally, the other end of the first locking member 81 is locked to the second locking member 82, so that the battery compartment mechanism 3 is locked and fixed in the locking cavity 83 through the cooperation of the first locking member 81 and the second locking member 82.

[0094] Specifically, the other end of the second locking member 82 is detachably connected to the other end of the first locking member 81 via a screw structure.

[0095] See Figure 12 This application also provides a second embodiment, which differs from the first embodiment only in the replacement of the locking mechanism. Specifically, in this second embodiment:

[0096] The locking mechanism 9 includes a first locking member 91 and a second locking member 92. The first locking member 91 is fixedly disposed on the outside of the functional device 4, and a locking position for locking the battery compartment mechanism 3 is formed between the second locking member 92 and the first locking member 91.

[0097] One end of the second locking member 92 is detachably connected to one end of the first locking member 91, and the other end of the second locking member 92 is detachably connected to the other end of the first locking member 91. The locking position is a locking cavity 93 for surrounding the battery compartment mechanism 3.

[0098] In this embodiment, both ends of the first locking member 91 are provided with latching components 94, and both ends of the second locking member 92 are detachably connected to the latching components 94 at both ends of the first locking member 91. In other implementations, both ends of the second locking member 92 can also be detachably connected to the second locking member 91 by screws.

[0099] In this embodiment, the latching assembly 94 includes a latching member 941 and a second spring 942. Two parallel latching brackets 911 are provided at one end and the other end of the first locking member 91. The latching member 941 is hinged between the two latching brackets 911 in the middle. One end of the second spring 942 is connected to the first locking member 91, and the other end of the second spring 942 is connected to one end of the latching member 941. The other ends of the latching members 941 of the two latching assemblies 94 are detachably latched to both ends of the second locking member 92. By pressing one end of the latching member 941, the latching member 941 rotates around its middle portion and compresses the second spring 942. At this time, the other ends of the two latching members 941 are relatively far apart, so as to release the originally locked second locking member 92 or to install the second locking member 92. When one end of the latching member 941 is released, under the action of the second spring 942, the latching member 941 rotates around its middle portion to reset. At this time, the other ends of the two latching members 941 are relatively close together, so as to engage and lock the second locking member 92 located between the other ends of the two latching members 941.

[0100] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
