Description

TECHNICAL FIELD

[0001] The utility model relates to a toy technical field especially involves a kind of waterproof structure of water-involved toy with the power supply function to the sealed cavity outside. BACKGROUND

[0002] In order to improve the playability and interest of toy, more and more functions are integrated on the toy, such as water spraying, mist, sound and light, interaction and so on. Water-involved toys such as toy boats and amphibious vehicles usually have a sealed cavity. One purpose is to install waterproof components such as batteries and electric parts. The other purpose is to make the toy have better buoyancy. As mentioned above, more and more functions are integrated on the toy, such as mist and light, which need to be set outside the sealed cavity. At present, the power supply mode for these functional components is usually as follows: a wire hole is set on the toy shell to communicate with the sealed cavity. The wire harness passes through the wire hole to connect to the functional components. At the same time, waterproof glue is applied at the wire hole position for waterproof treatment. Although this method is simple, the waterproof sealing effect cannot be guaranteed. Moreover, the waterproof effect cannot be tested after the finished product is completed. If water enters the sealed cavity, the battery and motor components are easily damaged, resulting in a relatively high rate of defective products, which is prone to consumer complaints and other problems. SUMMARY

[0003] The utility model aims at providing a waterproof structure of water-involved toy with power supply function to the sealed cavity outside, which can lead the power supply from the sealed cavity of the toy to the outside of the toy, and has good sealing and waterproof effect.

[0004] To achieve the above-mentioned purpose, the utility model discloses a waterproof structure of water-involved toy with power supply function to the sealed cavity outside, which includes a shell, a sealing element and a terminal assembly.

The gap between the shell and the circuit board is sealed by the sealing member, so that the water outside the shell can enter the sealed cavity, waterproof is realized, the waterproof structure is not easily damaged, the connection of the terminal interface does not affect the stability of the waterproof structure, and the waterproof reliability is high. In addition, the segmented wiring is realized through the terminal assembly, so that the assembly and maintenance of the product are facilitated.

By tightening the locking screw, the terminal assembly and the sealing member can be tightly installed and fastened, waterproof is ensured, and connection is convenient.

[0007] Preferably, the terminal assembly is directionally installed relative to the shell. That is, the uniqueness of the position of the terminal assembly relative to the shell is ensured, so as to avoid the wrong connection when there are multiple terminal interfaces. In the case, the directional installation of the terminal assembly relative to the shell can be realized through the alignment of the three blind holes and the corresponding through holes.

[0008] Preferably, the sealing member is provided with a limiting groove on the side close to the circuit board, and the shape of the limiting groove is matched with the shape of the circuit board. Through the arrangement of the limiting groove, the circuit board can be embedded into the limiting groove during assembly, and then the circuit board and the shell are connected, so that the assembly is facilitated. In addition, the waterproof sealing performance of the contact surface between the circuit board and the shell can also be ensured.

[0009] Preferably, the limiting frame matched with the shape of the circuit board or the sealing member is arranged on the inner wall of the shell. After such an arrangement, the positioning and installation of the terminal assembly and the sealing member are facilitated, in addition, when the shape of the sealing member is matched with the limiting frame, the sealing member and the limiting frame can be tightly connected, so as to further enhance the waterproof sealing performance between the circuit board and the shell.

[0010] Preferably, the terminal interfaces are arranged side by side on the circuit board or arranged in an array, all the terminal interfaces form an interface group, and the shapes of the communication hole and the via hole are matched with the shape of the interface group.

Moreover, this waterproof structure is not easily damaged, and the connection of the terminal interface does not affect the stability of the waterproof structure, resulting in high waterproof reliability. In addition, segmented wiring through the terminal assembly facilitates product assembly and maintenance. Attached Figure Description

[0031] 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.

[0032] like Figures 1-9 As shown, this utility model discloses a waterproof structure for a water-based toy with a function of supplying power to the outside of a sealed cavity. It includes a shell 10, a sealing element 30, and a terminal assembly 20. The shell 10 has a sealed cavity 11 and a connecting hole 12, through which the sealed cavity 11 can connect to the outside of the shell 10. The sealed cavity 11 can be used to house a control board, battery, motor, etc. The sealing element 30 and terminal assembly 20 in this invention are also placed within the sealed cavity 11.

[0033] The terminal assembly 20 includes a circuit board 21 and at least one terminal interface 22. This embodiment uses four terminal interfaces 22 as an example. The four terminal interfaces 22 are disposed on the same side of the circuit board 21 and arranged side-by-side, with the spacing between adjacent terminal interfaces 22 being as small as possible. All terminal interfaces 22 constitute an interface group. In this embodiment, the terminal interface 22 is preferably a female terminal interface 22 for easy connection. The terminal interface 22 has at least two pins 23, typically two, corresponding to the positive and negative terminals of the power supply, respectively. The side of the circuit board 21 without the terminal interfaces 22 is a printed circuit layer 24. The pins 23 pass through the circuit board 21 and are connected to the printed circuit layer 24 by solder 25. The fully soldered solder 25 can seal the holes through which the pins 23 pass through the circuit board 21, ensuring the waterproof performance between the terminal interface 22 and the circuit board 21. Alternatively, an adhesive can be applied to the circuit board 21 to form a waterproof film to enhance the waterproof performance.

[0034] The circuit board 21 is detachably connected to the inner wall of the housing 10, and the terminal interface 22 is placed in the connecting hole 12. Preferably, the terminal interface 22 extends out of the connecting hole 12 to facilitate terminal connection. The sealing member 30 is pressed between the circuit board 21 and the housing 10, and a through hole 31 is provided on the sealing member 30 for the terminal interface 22 to pass through. The shape of the connecting hole 12 and the through hole 31 is adapted to the shape of the interface assembly, which can facilitate the opening of the connecting hole 12 as much as possible and make the connecting hole 12 as small as possible, thereby reducing the risk of waterproof failure. The connecting hole 12 is waterproofly sealed by the sealing member 30 and the circuit board 21, while the terminal interface 22 can be exposed to the outside of the housing 10 for connection of functional components such as lights, sprayers, and speakers installed on the outside of the housing 10 to realize power supply and control.

[0035] In this case, the circuit board 21 is secured to the housing 10 by locking screws 26. At least two locking screws 26 are provided; in this case, three locking screws 26 are arranged in a triangular pattern. The housing 10 has blind holes 13 corresponding to each locking screw 26. The cavity of each blind hole 13 communicates with the sealing cavity 11. The locking screws 26 pass through the circuit board 21 and the seal 30 sequentially before being threaded into the blind holes 13. Both the circuit board 21 and the seal 30 have through holes 27 / 33 for the locking screws 26 to pass through. The locking screws 26 can be self-tapping screws without internal threads in the blind holes 13, or they can be ordinary screws with internal threads in the blind holes 13, allowing them to be directly screwed into them. The blind holes 13 prevent the inner and outer parts of the housing 10 from communicating through the locking screw connections, ensuring waterproofing. By tightening the locking screws 26, the terminal assembly 20 and the seal 30 can be securely installed, ensuring waterproofing and easy connection. Furthermore, the three locking screws 26 are arranged in a triangle, and correspondingly, the through holes 27 / 33 and the blind hole 13 are also arranged in a triangle. By aligning the through holes 27 / 33 with the blind hole 13, the terminal assembly 20 can be oriented relative to the housing 10, ensuring accurate wiring of functional components.

[0036] To ensure effective waterproofing and sufficient space for the through-hole 27, and to reliably secure the circuit board 21 within the housing 10, the distance from each terminal interface 22 to each edge of the circuit board 21 must be no less than 3mm. This provides sufficient space for the circuit board 21 to press against the seal 30. The circuit board 21 also possesses sufficient strength; once secured, the waterproof seal is not easily damaged, ensuring high reliability.

[0037] To facilitate installation and enhance waterproof sealing, a limiting groove 32 is provided on the side of the seal 30 that fits against the circuit board 21. The shape of the limiting groove 32 is adapted to the shape of the circuit board 21, allowing the circuit board 21 to be embedded in the limiting groove 32. Simultaneously, a limiting frame 14, adapted to the shape of the seal 30, is provided on the inner wall of the outer casing 10. During installation, the circuit board 21 is first inserted into the limiting groove 32, and then both are inserted into the limiting frame 14. Tightening the locking screw 26 completes the installation, which is convenient, quick, and accurately positioned. Furthermore, the seal 30 is made of an elastic material, such as rubber or silicone. When the locking screw 26 is tightened, the seal 30 can be deformed to a certain extent, allowing it to fit well against the circuit board 21 and the outer casing 10, thus ensuring waterproof sealing performance.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
