[0031] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a particular order or sequence.

[0032] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0033] As shown in Figures 1-6 The present application provides a switch assembly suitable for a mower, which comprises:

[0034] a contact switch 100;

[0035] a first operating member 300 vertically movably arranged on a mower operating handle 200;

[0036] a second operating member 400 rotatably arranged on the mower operating handle 200;

[0037] and a trigger member 500 movably arranged on the first operating member 300, the trigger member 500 can be driven by the first operating member 300 to move from a first working position to a second working position, the trigger member 500 can be driven by the second operating member 400 to move from the second working position to a third working position, when the trigger member 500 is in the third working position, the trigger member 500 closes the contact switch 100, thereby starting the mower.

[0038] Further, the operation handle 200 is hollow inside to form a receiving cavity, the first operation member 300 comprises a power switch 310 and a mounting seat 320, the power switch 310 is movably arranged in the receiving cavity along the vertical direction, the operation handle 200 is provided with an opening for the power switch 310 to extend out of the operation handle 200, the mounting seat 320 is fixedly arranged on the power switch 310, and the trigger member 500 is rotatably arranged on the mounting seat 320. The power switch 310 can be pressed to drive the trigger member 500 to move from the first working position to the second working position, and when the trigger member 500 is in the second working position, the height position of the trigger member 500 is the same as the height position of the contact switch 100. At this time, the trigger member 500 can be pushed by the second operation member 400 to move to the third working position.

[0039] The first reset member (not shown in the figure) is arranged between the power switch 310 and the operation handle 200, and can be implemented by a common material with elastic potential such as a compression spring. One end of the first reset member is connected to the power switch 310, and the other end of the first reset member is connected to the operation handle 200. The first reset member is adapted to exert a force on the power switch 310 to push the power switch 310 to drive the trigger member 500 to move from the second working position to the first working position. The power switch 310 is preferably a self-locking switch, that is, after the power switch 310 is pressed, it will be self-locked. After the power switch 310 is released, the power switch 310 will not be pushed by the first reset member to drive the trigger member 500 to move from the second working position to the first working position. The power switch 310 needs to be pressed again to release the self-locking. After the power switch 310 is released from the self-locking, the power switch 310 will be pushed by the first reset member to drive the trigger member 500 to move from the second working position to the first working position.

[0040] Further, the second operation member 400 comprises a connecting rod 410 and two trigger switches 420. The connecting rod 410 is rotatably arranged in the receiving cavity, and the two ends of the connecting rod 410 extend out of the operation handle 200 to be connected with the two trigger switches 420 respectively. The two trigger switches 420 are located below the operation handle 200. While holding the operation handle 200, the user can pull the trigger switches 420 towards the operation handle 200, so that the connecting rod 410 can rotate from the initial position to the trigger position. The connecting rod 410 is provided with an extension arm 430 for pushing the trigger member 500. When the connecting rod 410 is in the trigger position, the extension arm 430 can push the trigger member 500 from the second working position to the third working position. Since the two trigger switches 420 are in transmission connection with the connecting rod 410, when any one of the two trigger switches 420 is pulled, the contact switch 100 can be closed.

[0041] It is worth mentioning that the trigger 500 in the first working position is not at the same height position as the connecting rod 410 and the contact switch 100, and the trigger 500 in the second working position and the third working position is at the same height position as the connecting rod 410 and the contact switch 100. In short, when the trigger 500 is in the first working position, the connecting rod 410 and the extension arm 430 cannot directly push the trigger 500 from the first working position to the third working position, the contact switch 100 cannot be closed and turned on, and the lawn mower cannot be started. When the trigger 500 is in the second working position, the connecting rod 410 and the extension arm 430 can push the trigger 500 to the third working position, the contact switch 100 is closed and turned on, and the lawn mower is started.

[0042] The connecting rod 410 is further provided with a reset arm 440, and a second reset member (not shown in the figure) is arranged between the reset arm 440 and the operating handle 200. The second reset member is preferably a compression spring. One end of the second reset member is connected with the operating handle 200, and the other end of the second reset member is connected with the reset arm 440. The second reset member is adapted to continuously exert a force on the connecting rod 410 to move to the initial position, so that the connecting rod 410 can be reset to the initial position when the external force acting on the trigger switch 420 is removed. A third reset member (not shown in the figure) is arranged between the trigger 500 and the mounting seat 320. The third reset member is preferably a torsion spring. Both ends of the torsion spring are connected with the trigger 500 and the mounting seat 320 respectively. The torsion spring is adapted to continuously exert a force on the trigger 500 to move to the second working position, so that the trigger 500 can move to the second working position after the connecting rod 410 is reset to the initial position. Based on the second reset member and the third reset member, when the trigger switch 420 is released, the connecting rod 410 can be automatically reset to the initial position, and the trigger 500 can be reset to the second working position, the contact switch 100 is disconnected, and the lawn mower is stopped. That is, the trigger switch 420 must be pulled all the time to maintain the operation of the lawn mower.

[0043] In some preferred embodiments, the extension arm 430 is provided with a protruding first abutting portion 450, and the trigger 500 is provided with a protruding second abutting portion 510. When the extension arm 430 pushes the trigger 500 to the third working position, the first abutting portion 450 and the second abutting portion 510 are adapted to abut each other to limit the position of the connecting rod 410 and the extension arm 430, prevent the trigger switch 420 from driving the connecting rod 410 and the extension arm 430 to further rotate, and avoid the connecting rod 410 and the extension arm 430 from further rotating to push the trigger 500 to move, resulting in damage to the contact switch 100 caused by the trigger 500.

[0044] In summary, when the mower is used, the power switch 310 needs to be pressed first, and then the trigger switch 420 is pulled to close the contact switch 100 to make the mower start. If the power switch 310 is not pressed, only pulling the trigger switch 420 cannot close the contact switch 100 to make the mower start, thereby improving the safety of the mower. At the same time, the operation modes of the power switch 310 and the trigger switch 420 are different, the power switch 310 is a press trigger, the trigger switch 420 is a pull trigger, and the positions of the two are different, so that the user can avoid confusing the power switch 310 and the trigger switch 420 to cause the user to mistakenly touch the power switch 310 or the trigger switch 420.

[0045] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application.
