[0002] In the current field of remote controller design, a common problem is that due to the traditional design which needs to integrate spring contacts on the PCB board to realize the conductive connection with external elements, such design structure limits the overall sealing of the remote controller in physics. Although the spring contacts provide good electrical contact performance, the gap and movable parts thereof make it difficult for the remote controller to meet the standard of liquid leakage prevention.

[0003] When the battery inside the remote controller leaks due to long-term use or improper storage, the electrolyte inside the battery will penetrate along the gap between the spring contact and the PCB board, and then directly contact the PCB surface and the electronic components thereon, resulting in damage to the PCB board and failure of the remote controller.

[0027] The following will be described in detail in combination with the accompanying Figures 1-4 The present application is further described in detail.

[0028] The embodiment of the present application discloses a liquid leakage prevention remote controller. Referring to Figure 1 , Figure 2 and Figure 3 , the liquid leakage prevention remote controller comprises a shell, a spring 2, a battery cover 3 and a PCB board, the shell is provided with a battery compartment 4, the upper part of the battery compartment 4 is provided with an opening, the battery compartment 4 is used for placing a battery, and the two sides of the battery compartment 4 are provided with embedding grooves 5. The spring 2 is provided with a positive / negative electrode, a connecting part 7 and a contact point 6, the positive / negative electrode is connected with the contact point 6 through the connecting part 7, the positive / negative electrode is arranged in the battery compartment 4, and the connecting part 7 extends to the outside of the battery compartment 4 along the embedding groove 5 and is provided with the contact point 6. The battery cover 3 is arranged at the opening and is welded and fixed with the battery compartment 4, the connecting part 7 is sealed and fixed in the embedding groove 5 after the battery cover 3 and the battery compartment 4 are fused, and the spring 2 is fixed by pressing the connecting part 7 through the battery cover 3 in the embodiment. When the spring 2 is fixed, the contact point 6 can be in conductive contact with the contact disc of the PCB board. Since the contact point 6 is located outside the battery compartment 4, the fusion sealing of the battery cover 3 to the battery compartment 4 can avoid the leakage of the battery from the battery compartment 4 when the battery leaks, and can ensure that the PCB board will not be damaged by the leakage.

[0029] Continuing to refer to Figure 1 , in some embodiments, one end of the connecting part 7 is connected to the positive electrode or the negative electrode, the other end of the connecting part 7 is connected to the contact point 6, and the extension directions of the contact point 6 and the positive / negative electrode are not in the same direction. In the embodiment, the two ends of the connecting part are connected to the positive / negative electrode and the contact point 6 respectively, and the middle part extends along the embedding groove 5, so that the extension directions of the contact point 6 and the positive / negative electrode are different and extend in perpendicular directions. Therefore, when the PCB board presses the contact point 6, the contact point 6 can be more stably contacted.

[0030] In some embodiments, a fixing part is further arranged outside the battery compartment 4, and the contact point is installed on the fixing part.

[0031] In the embodiment, the fixing part is a fixing sleeve 8, and the contact 6 is installed in the fixing sleeve 8. The fixing sleeve 8 limits the installation position of the contact 6, so that the installation position of the contact 6 is accurate. A let-out groove 9 is formed on one side of the fixing sleeve 8, the connecting part 7 is inserted along the let-out groove 9, one end of the connecting part 7 extends into the fixing sleeve 8 in the vertical direction of the let-out groove 9, the contact 6 extends into the fixing sleeve 8, and one end extends out of the upper end surface of the fixing sleeve 8, so that the PCB board can press the contact 6 more stably.

[0032] In other embodiments, the fixing part can also be a fixing column, and the contact is sleeved on the fixing column.

[0033] Referring to Figure 4 and Figure 5 In some embodiments, the shell includes an upper cover 10 and a lower cover 1, the lower cover 1 is provided with a battery compartment 4, the PCB board is installed on the upper cover 10, and the upper cover 10 is detachably connected with the shell 1. The upper cover 10 and the shell 1 can be detachably connected through screwing, clamping or the like.

[0034] When the upper cover 10 is installed on the lower cover 1, the contact disc of the PCB board compresses the contact 6. At this time, the PCB board can stably contact the contact 6 to realize electrical connection.

[0035] The implementation principle of the liquid leakage prevention remote controller in the embodiment is that the battery cover 3 fixes the spring 2 through a welding fixing mode, and seals the battery compartment 4 after melting. Even if the battery leaks, the leakage can be prevented from flowing out of the battery compartment 4, and the damage to the internal circuit of the remote controller is prevented, so that corrosion of the PCB board can be prevented.
