The key feels good. The point sealing process of the electronic key 6 is cancelled, and the assembly and maintenance are good.

[0039] Specifically, in the present embodiment, the shell 1 is made of aluminum alloy material, such as ADC12 type aluminum alloy. The front surface of the shell 1 is formed with a through hole 7. The inside of the shell 1 is provided with at least two mounting columns 8. The mounting columns 8 are arranged on both sides of the through hole 7. The mounting columns 8 extend downward from the bottom surface of the through hole 7, so as to adapt to the installation of the trigger 2. The shell 1 is directly formed on the front lock panel of the intelligent door lock when the intelligent door lock is applied to the waterproof key structure.

[0040] Further, in the embodiment, the electronic button 6 is integrated on the circuit board 3, the circuit board 3 is installed in the shell 1, and the upper end of the electronic button 6 faces the through hole 7. The electronic button 6 is a Swich electronic button 6, and the electronic button 6 can be used to control the door lock to open. When the electronic button 6 is triggered, the circuit board 3 controls the door lock to open. The circuit board 3 can be fastened and installed by being connected with the shell 1 through screws.

[0041] Further, in the embodiment, the waterproof member 4 is made of 60-degree soft silicone material, has a cover structure, is sleeved on the electronic button 6, has a lower end surface abutting against the surface of the circuit board 3, and has an upper end surface abutting against the inner surface of the shell 1. The circuit board 3 presses the waterproof member 4 in the shell 1, and the waterproof member 4 encloses the electronic button 6 to achieve waterproofing. The waterproof effect is good, and the whole machine meets the IPX5 level requirement of salt spray testing. Finally, the bottom plate 5 is installed on the bottom surface of the shell 1, and the circuit board 3 is enclosed in the shell 1 by the bottom plate 5. The bottom plate 5 is preferably made of ABS material. Preferably, the surface of the circuit board 3 is coated with a waterproof layer. In this way, when the waterproof member 4 is sleeved on the electronic button 6, only the edge part of the electronic button 6 needs to be sleeved to achieve good waterproof effect.

[0042] Further, in the embodiment, the trigger 2 is integrally formed by plastic, such as ABS and / or PC. The trigger 2 is used to trigger the electronic button 6 to be turned on. The trigger 2 includes a trigger part 9, an elastic arm 10, and a mounting part 11. The trigger part 9 is connected with the mounting part 11 through the elastic arm 10, the mounting part 11 is fastened and installed on the mounting column 8, the upper end of the trigger part 9 penetrates through the through hole 7 and is exposed on the front surface of the shell 1, and the lower end of the trigger part 9 abuts against the waterproof member 4. Driving the trigger part 9 can trigger the electronic button 6. The elastic arm 10 has elasticity and can rebound the trigger part 9. In actual application, the mounting part 11 is fastened and installed on the mounting column 8 through screws. An external force presses and drives the trigger 2, the trigger part 9 is pressed downward, the lower end of the trigger part 9 presses the waterproof member 4 and continues to press the electronic button 6, so that the electronic button 6 is triggered. When the external force is removed, the trigger part 9 is automatically reset under the rebounding action of the elastic arm 10. Preferably, a limiting ring 12 is formed on the trigger part 9, the limiting ring 12 limits the trigger 2 on one side of the through hole 7, and the elastic arm 10 is arranged along the outside of the limiting ring 12.

[0043] Further, in the embodiment, the middle part of the waterproof member 4 is provided with a partition layer 13, which separates the waterproof member 4 into an upper cavity 14 and a lower cavity 15. The lower cavity 15 is sleeved with the electronic button 6, and the bottom end of the lower cavity 15 abuts against the surface of the circuit board 3. The circuit board 3 presses the waterproof member 4 in the shell 1, and the lower cavity 15 seals the electronic button 6 to achieve waterproof. Preferably, the inner cavity shape of the lower cavity 15 is adapted to the outer shape of the electronic button 6. The inner cavity shape of the lower cavity 15 is designed by profiling, so that the inner cavity shape of the lower cavity 15 is consistent with the outer shape of the electronic button 6, so that the electronic button 6 is not displaced when it is sleeved with the waterproof member 4, causing waterproof failure. In order to reduce the driving stroke of the trigger 2, in the embodiment, the lower end of the trigger part 9 abuts against the upper surface of the partition layer 13, and the upper end of the electronic button 6 abuts against the lower surface of the partition layer 13, achieving the effect that the trigger 2 has a better key feel experience. When the user drives the trigger 2, the electronic button 6 can be quickly triggered, thereby improving the unlocking rate and improving the user experience.

[0044] Further, in the embodiment, in order to improve the waterproof sealing effect of the waterproof member 4 on the electronic button 6, an annular protrusion 16 is arranged at the bottom end of the lower cavity 15, and the protrusion 16 abuts against the surface of the circuit board 3. When the circuit board 3 is tightly connected with the shell 1 and presses the waterproof member 4, the circuit board 3 provides sufficient pressure to make the protrusion 16 tightly adhere to the surface of the circuit board 3. In addition, the waterproof member 4 of the embodiment eliminates the glue dispensing process to seal the electronic button 6, has better assembly and maintenance, and is conducive to reducing costs.

[0045] Further, in the embodiment, in order to make the elastic arm 10 have sufficient deformation to meet the stroke requirement of the trigger 2, the length of the elastic arm 10 needs to be designed to be relatively long. Therefore, in order to facilitate the elastic arm 10 to pass through the waterproof member 4 for installation, two symmetrical grooves 17 are formed at the upper end of the upper cavity 14, and the elastic arm 10 is assembled through the grooves 17. At the same time, the arrangement of the grooves 17 can make the waterproof member 4 not interfere with or block the deformation of the elastic arm 10 when the trigger 2 is driven. It should be noted that in some embodiments, the upper cavity 14 can also seal the entire trigger 2 to form a waterproof structure. At this time, the area of the lower cavity 15 is correspondingly increased to seal most or the entire circuit board 3, so as to prevent the waterproof member 4 from not being pressed tightly enough when the circuit board 3 is clamped and installed, causing waterproof failure.

[0046] Further, in the embodiment, in order to improve the service life of the waterproof member 4 and prevent the partition layer 13 from being excessively worn to cause waterproof failure, a thickening layer 18 is arranged on the partition layer 13. The thickening layer 18 thickens the thickness of the partition layer 13, and the thickening layer 18 is integrated with the partition layer 13. In this way, the contact and wear of the trigger part 9 on the partition layer 13 will not be easily worn through, improving the service life of the waterproof member 4 and ensuring the waterproof effect of the waterproof member 4.

[0047] Each technical feature of the above-described embodiments can be combined with any other technical feature, and for the sake of brevity, not all possible combinations are described, but it is understood that the scope of the disclosure encompasses all such possible combinations.

[0048] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
