[0039] ​In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0040] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description will be described with reference to specific arrangements. It will be clear, however, that this is merely an example and is not intended to limit the present application. Furthermore, the present application can repeat reference numerals and / or letters in various examples. Such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and / or settings discussed.

[0041] For the purpose of description, spatial relative terms as shown in the drawings can be used to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement condition is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be subsequently oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0042] In order to solve the technical problem of poor waterproof performance of the battery in the prior art, the present application provides a waterproof battery box which can be applied to an underwater cleaning robot.

[0043] The underwater cleaning robot comprises a cabin body, a walking mechanism, a cleaning mechanism, a power mechanism and the like. The walking mechanism is arranged at the bottom of the cabin body, and the cleaning mechanism is arranged at the bottom and inside of the cabin body, so as to clean the underwater position to be cleaned such as a swimming pool or filter and clean the water body. The power module is arranged in the cabin body to provide power for the movement of the underwater cleaning robot. The power mechanism comprises a battery module. Since the underwater cleaning robot is mostly used underwater, the waterproof protection of the battery module is improved. A waterproof battery box is arranged outside the battery module, so that the waterproof protection of the battery module is realized and the waterproof performance is improved.

[0044] In a first aspect, Figures 1 to 3 The waterproof battery box 100 provided by the embodiment of the present application comprises an outer shell assembly 1, an inner shell assembly 2 and a water leakage detection assembly 3. The outer shell assembly 1 has a containing cavity 1a. The inner shell assembly 2 is arranged in the containing cavity 1a and has a battery cavity for containing a battery. The water leakage detection assembly 3 is arranged in the containing cavity 1a and located between the outer shell assembly 1 and the inner shell assembly 2. The water leakage detection assembly 3 is used to detect whether water enters the containing cavity 1a.

[0045] It can be understood that by arranging the battery in the battery cavity of the inner shell assembly 2 and then arranging the outer shell assembly 1 outside the inner shell assembly 2, the battery can be double waterproofed by the inner shell assembly 2 and the outer shell assembly 1, the waterproof performance is improved, and the risk of water entering and self-igniting of the battery module is reduced. At the same time, the water leakage detection assembly 3 is arranged between the outer shell assembly 1 and the inner shell assembly 2, so that water leakage can be detected before it occurs in the outer shell assembly 1 and enters the inner shell assembly 2. Thus, water leakage can be detected in advance, and warning can be given in advance when water affects the battery, so as to protect the battery.

[0046] In the technical solution of the embodiment, the water leakage detection assembly 3 comprises a water detection sensor for detecting whether water enters the containing cavity 1a and a fuse, and the fuse is electrically connected with the water detection sensor. The fuse is used to be electrically connected with the battery module.

[0047] Exemplarily, the water detection sensor can be a water immersion sensor. The water immersion sensor can detect whether water exists in the environment. In order to improve the sensitivity of the water leakage detection, the water immersion sensor is arranged at multiple positions of the inner shell assembly 2 and the outer shell assembly 1.

[0048] In the embodiment, the waterproof protection circuit is formed by the electrical connection among the water detection sensor, the battery module and the fuse. When the water immersion sensor detects water in the accommodating cavity 1a, the two electrodes of the water immersion sensor are in conduction and short circuit, and the fuse is fused, thereby protecting the battery module. Moreover, due to the second waterproof of the inner shell assembly 2 to the battery module, the battery module is properly protected at this time. Thereafter, the maintenance only needs to re-perform the waterproof, and the battery does not need to be replaced, thereby reducing the maintenance cost.

[0049] It should be noted that, Figure 3 It should be noted that,

[0050] In other embodiments, the water detection sensor is also electrically connected with the alarm module. When the shell assembly 1 leaks, the water leakage alarm prompt is sent through the alarm module.

[0051] As shown in Figures 1 to 3 In the technical scheme of the embodiment, the shell assembly 1 includes a bottom shell 11 and an upper shell 12. The bottom shell 11 and the upper shell 12 are detachably connected and enclose to form the accommodating cavity 1a. The bottom shell 11 and the upper shell 12 are fixedly connected by threads. The bottom shell 11 and the upper shell 12 are designed as a detachable connection structure, which is convenient for disassembly and assembly. The connection part of the bottom shell 11 and the upper shell 12 is provided with a waterproof sealing ring 4, which can realize the waterproof performance of the shell assembly 1.

[0052] As shown in Figure 2 and Figure 3 In the technical scheme of the embodiment, the number of the waterproof sealing ring 4 is at least two. In this way, by setting multiple waterproof sealing rings 4, the sealing and waterproof performance can be further improved.

[0053] As shown in Figure 2 and Figure 3 In the technical scheme of the embodiment, the side of the bottom shell 11 facing the upper shell 12 is provided with a sealing groove 11a, and the sealing groove 11a is provided with a waterproof sealing ring 4. The side of the upper shell 12 facing the bottom shell 11 is provided with a first convex ring 121, and the first convex ring 121 is inserted into the sealing groove 11a and presses the waterproof sealing ring 4.

[0054] It can be understood that the sealing groove 11a provides a mounting basis for the waterproof sealing ring 4, which facilitates the quick installation of the waterproof sealing ring 4.

[0058] In the embodiment, the first positioning groove 12a and the second positioning groove 11b are both L-shaped grooves, which provide support for the installation of the waterproof sealing ring 4. When the first convex ring 121 is inserted into the sealing groove 11a and the second convex ring 111 is inserted into the inner cavity of the upper shell 12, the cooperation of the first positioning boss 122 and the second positioning groove 11b is completed, and the cooperation of the second positioning boss 112 and the first positioning groove 12a is also completed.

[0059] In the embodiment, the number of waterproof sealing rings 4 is two. One waterproof sealing ring 4 is located between the first convex ring 121 and the groove bottom of the sealing groove 11a, and the other waterproof sealing ring 4 is located on the inner side of the first convex ring 121. In this way, double sealing and waterproof effects can be achieved. When one of the waterproof sealing rings 4 fails, the other waterproof sealing ring 4 can still play a sealing and waterproof role, reducing the risk of water entering the shell assembly 1.

[0060] As shown in Figure 1 In the technical scheme of the embodiment, the upper shell 12 is provided with an exhaust hole 12b which is sealed by filling sealant. Vacuumizing operation can be performed through the exhaust hole 12b, which can ensure the sealing performance of the waterproof battery box 100 and prevent internal oxidation and liquid leakage. After the vacuumizing operation is completed, sealant is filled in the exhaust hole 12b to ensure the sealing and waterproof performance.

[0061] As shown in Figures 1 to 3 The shell assembly 1 is also provided with a power supply interface 122 and a charging interface 123, which can realize charging and discharging of the battery module.
