Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] Please also read Figures 1 to 8 , the sealed housing mechanism provided by the embodiment of the present application is now described. The sealed housing 10 mechanism includes a cover 20, the cover 20 is provided with a first wire groove 22; the cover 20 introduces the cable through the wire hole to ensure that the wire can pass smoothly and connect to the circuit board 30; the housing 10, the housing 10 is sleeved on the cover 20 to form a sealed area; one side of the housing 10 includes at least a first plane 11, forming a first step, and the first plane 11 is tightly fitted with one side of the circuit board 30; through the setting of the first step, a height difference is provided, so that the circuit board 30 can be firmly fixed in the sealed area, even if the circuit board 30 is not fixed by screws, it can be stably fixed in the housing 10.

[0035] The other side of the shell 10 also includes a second plane 12, which forms a second step with the shell 10. The second step is perpendicular to the second plane 12, and a through hole 13 is opened on the plane of the second step to allow the wires to pass through. The through hole 13 is designed for the wiring and connection of the wires to ensure that the wires can pass smoothly without affecting the sealing performance of the shell 10.

[0036] In one embodiment of the present application, a first distance L1 from the top of the shell 10 to the top of the first step is greater than or equal to a second distance L2 from the top of the shell 10 to the top of the second step; and the height of the first step is less than the height of the second step, wherein the length from the top of the shell 10 to the top of the second step depends on the position on the circuit board 30 where the output cable needs to be connected, when the output cable is close to the top of the circuit board 30, the first distance L1 is equal to the second distance L2, and when the output cable is far from the top of the circuit board 30, the first distance L1 is greater than the second distance L2, and the setting of the second step can effectively avoid the output cable occupying the position of the sealing area and shorten the length of the output cable.

[0037] In one embodiment of the present application, the cover body 20 has a first protrusion 21 extending outward, and the first protrusion 21 is provided with a first wire groove 22. The cover body 20 is provided with a first wire groove 22, and the first wire groove 22 is arranged in an 8-shape. By setting the first protrusion 21, the thickness of the cover body 20 at the position of the first wire groove 22 is made thicker, and the impact resistance of the wire groove area of ​​the cover body 20 is improved to prevent damage caused by external impact or other physical forces. The first wire groove 22 is designed to be in an 8-shape, so that the wires can be more firmly fixed in the groove to prevent movement or falling off during use. The structural design of the 8-shaped wire groove provides additional support and fixation to prevent the wires from being affected by tension or pressure when passing through the shell 10.

[0038] In one embodiment of the present application, the cover 20 is provided with a support column 24 for supporting the circuit board 30. The support column 24 abuts against the bottom of the circuit board 30, and the top of the support column 24 abuts against the bottom of the circuit board 30, providing additional support for the circuit board 30 to prevent displacement or shaking during use. The distance from the top of the support column 24 to the top of the first step of the housing 10 is slightly greater than the height of the circuit board 30; wherein the height of the support column 24 is adjusted and set according to the height of the housing 10 and the height of the circuit board 30, ensuring that the circuit board 30 can be installed into the sealed area.

[0039] Optionally, the support column 24 is integrally injection molded with the cover body 20. The support column 24 may be a cylindrical or polygonal column with a flat top to facilitate abutment against the bottom of the circuit board 30. The support column 24 may be made of insulating material to prevent the circuit board 30 from short circuiting or electrical interference. Optionally, a rubber pad or shock-absorbing material may be attached to the support column 24 to further improve the stability and durability of the circuit board 30.

[0040] In one embodiment of the present application, the width of the shell 10 gradually decreases from the bottom end of the shell 10 to the top end of the shell 10, and the width of the top end is slightly larger than the width of the circuit board 30, ensuring that the circuit board 30 can be easily installed in the shell 10 and can remain stable during use.

[0041] In one embodiment of the present application, the second step has a through hole 13, and the first sealing component 15 cooperates with the edge of the through hole 13 to ensure that the housing 10 forms an effective seal during installation. The first sealing component 15 is provided with a second wire groove 152 for allowing the wires to pass through. The second wire groove 152 is used to connect the output cable from the circuit board 30. Through the cooperation of the second step and the first sealing component 15, the portion of the cable in the housing 10 can be reduced, which can avoid the cable occupying the space of the sealing area.

[0042] The first sealing component 15 has a slot 151, and the slot 151 enables the first sealing component 15 to engage with the edge of the through hole 13 when inserted into the through hole 13; the slot 151 is located in the middle area of ​​the first sealing component 15, which can ensure that the first sealing component 15 can be tightly engaged with the edge of the through hole 13 during installation to provide a better sealing effect. The shape and size of the slot 151 match the edge of the through hole 13 to ensure that the sealing component can be firmly fixed on the shell 10 during the installation process.

[0043] During installation, the first sealing component 15 is inserted into the through hole 13 of the housing 10 through its slot 151. The design of the slot 151 enables the first sealing component 15 to engage with the edge of the through hole 13 to ensure tight sealing performance after the component is installed.

[0044] The first sealing component 15 is usually made of a flexible sealing material, such as rubber, silicone or polyurethane, to ensure that it has good sealing performance.

[0045] In one embodiment of the present application, at least one notch 23 is provided at the upper end of the first protrusion 21 at the edge where the cover body 20 is mounted in cooperation with the shell 10, and the shell 10 has at least one second protrusion 14 extending outward from the shell 10, and the second protrusion 14 cooperates with the notch 23. The second protrusion 14 extends outward from the shell 10 and can be located on the side of the shell 10, serving as a structural element for fixing or locking the cover body 20; the notch 23 is located on the edge where the cover body 20 is mounted in cooperation with the shell 10, providing an accommodation space and a docking position for the second protrusion 14, and the second protrusion 14 cooperates with the notch 23. The design of the second protrusion 14 and the cooperation with the notch 23 enable the cover body 20 to be firmly installed on the shell 10, and can ensure that it will not loosen or move due to external forces during use. During installation, the edge of the cover body 20 is inserted into the second protrusion 14 of the shell 10 and fully cooperates with the notch 23, which not only increases the accuracy during assembly, but also ensures the stability of the entire structure. When the cover body 20 needs to be removed, the cover body 20 can be easily pulled out of the shell 10 because the cooperation design of the second protrusion 14 and the notch 23 reduces the possibility of damage or jamming caused by over-tightening.
