Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Generally, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0030] As Figures 1 to 6 , a rocker structure of a marine lamp in this embodiment includes a rocker 1, a fixed seat 2, a push block 3, a return spring 4, a pressing seat 5, a switch device 6, and a base 7;

[0031] The fixed seat 2 and the base 7 are distributed up and down. The fixed seat 2 is provided with a movable cavity 21 with an open bottom. The top surface of the movable cavity 21 has a spherical groove 211 with a gradually decreasing diameter upward (as Figure 5 ), and the top surface of the fixed seat 2 has a guide groove 22 communicating with the spherical groove 211;

[0032] The lower end of the rocker 1 is rotatably connected to the base 7. The upper end of the rocker 1 passes through the movable cavity 21 and the guide groove 22, and the upper end of the rocker 1 can move in the guide groove 22 with the lower end as a fulcrum;

[0033] The switch device 6 is at least two and is circumferentially spaced and arranged around the lower end of the rocker 1;

[0034] The pushing block 3 and the pressing seat 5 are arranged at intervals between the upper and lower ends of the rocker 1;

[0035] The pressing seat 5 is located above the switch device 6 and triggers the switch device 6 as the rocker 1 moves; the pushing block 3 is slidably sleeved on the rocker 1 and is located in the moving cavity 21; the upper surface of the pushing block 3 is a spherical surface 31 that is slidably fitted to the spherical surface groove 211;

[0036] The return spring 4 is installed between the pushing block 3 and the pressing seat 5 and is used to provide an elastic force for the pushing block 3 to abut against the spherical surface groove 211.

[0037] Thus, in the structure of the rocker 1 of this embodiment, when the user manipulates the upper end of the rocker 1 to move in the guide groove 22, it will drive the pressing seat 5 to deflect and trigger the switch device 6 at the corresponding position to control the angular swing of the marine lamp or realize other functions; at the same time, due to the existence of the spherical surface groove 211, the rocker 1 will drive the pushing block 3 with the spherical surface 31 to slide down synchronously while moving, and when the pushing block 3 slides down, it will compress the return spring 4. Therefore, the elastic force of the return spring 4 can provide a certain control feedback effect, and the process of overcoming the elastic force improves the operation feel; and when the user releases the rocker 1, the elastic force of the return spring 4 will push the pushing block 3 to reset, driving the rocker 1 to reset, thereby realizing the automatic reset of the rocker 1 and improving the use convenience.

[0038] Such as Figure 4 and Figure 6 , in this embodiment, there are four switch devices 6, which are evenly distributed circumferentially at intervals; the guide groove 22 is a cross guide groove 22. And correspondingly, the pressing seat 5 can be in a disc shape.

[0039] The upper end of the rocker 1 can slide precisely back and forth along the four sliding grooves 221 of the cross guide groove 22, so as to realize the separate triggering of the four switch devices 6, and the structure of the rocker 1 of this embodiment can be used to control the marine lamp to adjust the lighting angles up, down, left and right, etc.

[0040] Such as Figures 2 to 4 , in this embodiment, the pushing block 3 is hemispherical, the upper surface of the pushing block 3 is the spherical surface 31, and the lower surface 32 of the pushing block 3 abuts against the upper end of the return spring 4; the upper part of the pressing seat 5 has an annular groove 51, and the annular groove 51 is used to accommodate the lower end of the return spring 4. This facilitates the cooperation of the return spring 4 with the pushing block 3 and the pressing seat 5. And the return spring 4 can be a tapered spring that is narrower at the top and wider at the bottom. It is convenient for the upper end of the return spring 4 to cooperate with the spherical surface groove 211 in the moving cavity 21.

[0041] Such as Figure 2, the pressing seat 5 is surrounded by the open side wall 212 of the moving cavity 21 of the fixed seat 2, and there is a moving gap between the side wall of the pressing seat 5 and the open side wall 212. The fixed seat 2 can be used to limit the pressing seat 5, avoid the deviation of the pressing seat 5, and ensure the reliable triggering of the switch device 6.

[0042] Again, Figure 4 , a plurality of fixed seat connecting columns 23 are provided on the outer periphery of the fixed seat 2. In this embodiment, fixed seat connecting columns 23 are respectively provided at the four corners of the fixed seat 2.

[0043] Base connecting columns 71 corresponding to the respective fixed seat connecting columns 23 are provided on the base 7; in this embodiment, base connecting columns 71 are respectively provided at the four corners of the base 7.

[0044] The fixed seat connecting column 23 and the base connecting column 71 can be connected and locked by screws (not shown in the figure), so that the fixed seat 2 and the base 7 are detachably locked and connected together. This facilitates the assembly operation of the product.

[0045] For example Figure 2 , in this embodiment, a spherical rotating groove 72 is provided on the base 7, and the lower end of the rocker 1 has a hemispherical portion 11 that is rotatably fitted in the rotating groove 72. Of course, the rotating groove 72 can also be provided at the lower end of the rocker 1, and the hemispherical portion 11 can be provided on the base 7, as long as the rotational fit between the two can be achieved, and it is not limited to this embodiment.

[0046] For example Figures 1 to 3 , the structure of the rocker 1 in this embodiment further includes a housing 8 and a circuit board 9.

[0047] The rocker 1, the fixed seat 2, the push block 3, the return spring 4, the pressing seat 5, the switch device 6, the base 7, and the circuit board 9 can all be arranged inside the housing 8; the housing 8 is used to protect the structure of the rocker 1.

[0048] The housing 8 in this embodiment may include an upper cover plate 81 and a lower housing 82, which are detachably combined together to wrap the various components.

[0049] In this embodiment, the upper end of the rocker 1 extends out of the housing opening 811 provided at the top of the housing 8, and an elastic rocker sleeve 10 is provided at the housing opening 811; the elastic rocker sleeve 10 is sleeved on the upper end of the rocker 1 and closes the housing opening 811. The elastic rocker sleeve 10 can be made of materials such as rubber or silica gel to have elasticity, can move along with the rocker 1, and at the same time, can protect the housing opening 811 from dust and water, making the structure of the rocker 1 more suitable for the humid and water-rich environment on the ship, improving the service life of the structure of the rocker 1, and ensuring the reliable control of the marine lamp.

[0050] The circuit board 9 is also disposed within the outer shell 8; the circuit board 9 can be located below the base 7, and the circuit board 9, the base 7, and the fixing base 2 are all locked and fixed within the outer shell 8; the circuit board 9 can be cooperatively locked to the outer shell 8 in cooperation with the base connection column 71 and the fixing base connection column 23 of the base 7 and the fixing base 2 respectively.

[0051] The switch device 6 is mounted on the circuit board 9, and the base 7 has a relief hole 73 for the switch device 6 to pass through. Structures such as a remote control component (not shown in the figure) can be provided on the circuit board 9 for cooperating with the rocker 1 structure to trigger the switch device 6, so as to realize the remote control of the marine lamp.
