[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] The inner wall of the existing battery compartment needs to be opened with a clearance hole for the conductive components to be installed in the battery compartment. The size of the clearance hole needs to be no smaller than the size of the conductive components. At the same time, the battery may leak due to long-term use. The corrosive liquid generated by the battery leakage can easily enter the remote control through the clearance hole and contaminate the circuit board, affecting the normal use of the circuit board.

[0029] In order to solve the above technical problems, this embodiment provides a battery compartment anti-leakage connection structure, please refer to Figures 1 to 4 As shown, Figure 1 This is an exploded view of the battery compartment anti-leakage connection structure and the remote control in the embodiment. Figure 2 for Figure 1 Schematic diagram of area A in the middle. Figure 3 This is an exploded view of the remote control with the cover opened in the embodiment. Figure 4 for Figure 3 Schematic diagram of area B in the middle.

[0030] The battery compartment anti-leakage connection structure of this embodiment is as follows Figure 1 and Figure 3 As shown, it includes: a housing 1, a conductive component 2, a contact spring 3, a wire 4 and a circuit board 5.

[0031] like Figure 3 and Figure 4 As shown, the housing 1 is provided with a battery compartment 10, and two sets of conductive components 2 are provided inside the battery compartment. The two sets of conductive components 2 are configured to be electrically connected to the positive and negative poles of the battery in the battery compartment 10 respectively; Figure 1As shown, two contact springs 3 are provided on the housing 1, and are electrically connected to the two groups of conductive components 2 through wires 4, and the wires 4 pass through the battery compartment 10; the circuit board 5 is provided inside the housing 1 and is provided with two conductive contacts 50. The two conductive contacts 50 can be elastically pressed on the two contact springs 3 respectively, so that the contact springs 3 generate elastic force through compression and are tightly pressed against the conductive contacts 50 through the elastic force, so that the circuit board 5 is electrically connected to the contact springs 3.

[0032] When the leakage-proof connection structure of the battery compartment 10 and the remote control of the above technical solution are working, the batteries in the battery compartment 10 supply power to the circuit board 5 in sequence through the conductive component 2, the wire 4, the contact spring 3 and the conductive contact 50, wherein the conductive component 2 can be pre-installed in the battery compartment 10 and connected to the contact spring 3 through the wire 4 passing through the battery compartment 10 to realize the transmission of current toward the circuit board 5. In this way, there is no need to open a clearance hole in the battery compartment 10 to install the conductive component 2, which reduces the size of the channel for battery leakage to enter the circuit board 5, reduces the risk of battery leakage contaminating the circuit board 5, and thus improves the reliability and service life of the product.

[0033] In order to simplify the installation operation, in one embodiment of the above-mentioned conductive component 2, the wire 4 and the contact spring 3 are connected in sequence, refer to Figure 2 and Figure 4 As shown, the conductive component 2, wire 4, and contact spring 3 are integrally formed. The battery compartment 10 has an opening on the back, and a cover 11 is provided at the opening. The cover 11 is connected to the housing 1 and is configured to cover the opening. The cover 11 or the battery compartment 10 has a through-hole 12 for the wire to pass through. During installation, the conductive component 2 and contact spring 3 are positioned in predetermined positions. Finally, the cover 11 seals the opening of the battery compartment 10, and the wire 4 passes through the through-hole 12. This eliminates the need to connect the wire 4 to the conductive component 2 and contact spring 3.

[0034] It is understandable that the battery compartment 10 can also be integrated, without an opening and a compartment cover 11, and a through-hole 12 is provided. During installation, the conductive component 2 and the contact spring 3 are first installed in a preset position, and then the wire 4 is passed through the through-hole 12 and welded to the conductive component 2 and the contact spring 3 respectively. It is also possible to achieve electrical connection between the conductive component 2, the wire 4, and the contact spring 3 while ensuring the sealing performance of the battery compartment 10.

[0035] To facilitate the installation of contact spring 3 and improve its stability, refer to Figure 1 and Figure 2 As shown, the housing 1 is provided with a positioning hole 13, which is opposite to the conductive contact 50. One end of the contact spring 3 is provided in the positioning hole 13. The positioning hole 13 can quickly position the contact spring 3 when installing the contact spring 3, and limit the contact spring 3 so that it can accurately contact the conductive contact 50.

[0036] Further, see Figure 1 and Figure 2 As shown, the outer diameter of the contact spring 3 gradually decreases along the axial direction, and the end with the larger outer diameter is arranged in the positioning hole 13, and the end with the smaller outer diameter is in contact with the conductive contact 50. In this way, the truncated cone-shaped contact spring 3 can further improve its own stability, making it more stable when combined with the conductive contact 50.

[0037] In order to further improve the stability of the contact spring 3 and the conductive contact 50 and reduce the impact of vibration and collision on the stability of the two, refer to Figure 1 and Figure 3 As shown, the conductive contact 50 is a contact piece, and the contact piece is provided with a groove 51. The end of the contact spring 3 with a smaller outer diameter is positioned in the groove 51. With this arrangement, the two ends of the conductive spring are respectively limited by the groove 51 and the positioning hole 13. Combined with its own frustum-shaped structure, it is not easy to shake due to accidental dropping or bumping during use, and the structure is more stable.

[0038] Exemplarily, the groove 51 is a spherical groove or a cylindrical groove.

[0039] The circuit board 5 is provided in the housing 1 and is electrically connected to the contact spring 3 via the conductive contact 50. Figure 1 and Figure 3 As shown, the housing 1 includes a detachably connected upper shell 14 and a lower shell 15, the battery compartment 10 and the contact spring 3 are arranged on the lower shell 15, and the circuit board 5 is fixed on the upper shell 14; wherein, when the upper shell 14 is connected to the lower shell 15, the contact spring 3 can be elastically pressed on the conductive contact 50.

[0040] Exemplarily, the upper and lower shells 15 are connected by snaps or screws, and the circuit board 5 is fixed to the upper shell 14 by screws.

[0041] Exemplarily, the compartment cover 11 is connected to the lower housing 15 by snaps or screws, and a waterproof structure with a sealing ring is provided between the openings of the battery compartment 10 .

[0042] This embodiment provides a remote controller, see Figure 1 As shown, the remote control includes the above-mentioned anti-leakage connection structure of the battery compartment 10. Through the application of the above-mentioned anti-leakage connection structure of the battery compartment 10, the remote control not only extends the service life of the product and reduces the maintenance cost caused by battery leakage, but also achieves a qualitative leap in user experience, so that users do not need to worry about the potential hazards caused by battery leakage during use, thereby enhancing the market competitiveness of the product.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
