Description

Technical Field

[0001] This application relates to the field of garden tools, and in particular to a switch assembly and power head for a garden tool. Background Technology

[0002] In existing power equipment (such as power tools, garden machinery, etc.), it is usually necessary to control the start / stop or working status of the motor through switching components. Traditional switching components usually use mechanical switches or electronic switches, but these solutions have the following problems: complex structure, large space occupation, and some switching components use multi-stage linkage mechanisms, resulting in a complex overall structure, which is not conducive to miniaturization design, especially in power equipment with limited space. Utility Model Content

[0003] The purpose of at least one specific embodiment of this utility model is to overcome the defects of the prior art and provide a switching assembly and a power head.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A switching assembly, comprising:

[0006] Fasteners;

[0007] A trigger element, which is rotatably connected to a fixing element by fasteners;

[0008] A micro switch, which is located on one side of the trigger element;

[0009] The operating element has one end connected to the trigger element;

[0010] When the operating element is activated, it causes the trigger element to rotate relative to the fixed element around the fastener, thereby activating the micro switch.

[0011] Furthermore, an elastic element connects the trigger and the fixed element. When the operating element drives the trigger to rotate relative to the fixed element, the deformed elastic element drives the trigger to reset.

[0012] Furthermore, the triggering component includes a connecting part, a rotating part, a triggering part, and a supporting part, while the fixing component includes a main body part, a mounting part, and a fixing part;

[0013] The rotating part of the trigger is rotatably connected to the main body of the fixing part by a fastener. An elastic element is connected between the support part and the fixing part. The operating part passes through the mounting part and is connected to the connecting part. When the operating part drives the trigger to rotate relative to the fixing part, the trigger moves closer to or further away from the micro switch.

[0014] Furthermore, the trigger has a first position close to the micro switch and a second position away from the micro switch. When the trigger is in the first position, the trigger approaches and presses the micro switch, and the micro switch is in the open state.

[0015] When the trigger is in the second position, the trigger is away from the micro switch, and the micro switch is in the on state.

[0016] Furthermore, when the operating component is not activated, the trigger component is in the first position; when the operating component causes the trigger component to rotate relative to the fixed component, the trigger component is in the second position.

[0017] Furthermore, the operating component is a throttle control line, with one end connected to the connecting part and the other end extending into the operating area.

[0018] Furthermore, the outer side of the switch assembly is covered by a main housing, which has an opening. The connecting part of the trigger and the mounting part of the fixing part extend from the opening, and the opening provides the space required for the connecting part to swing.

[0019] Furthermore, the number of microswitches is one or more, and the microswitches are mounted on the fixing part of the fixing part, the surface and / or back of the fixing part providing the mounting area for the microswitches.

[0020] Furthermore, the operating component is provided with a protective sleeve, and the end of the protective sleeve near the trigger component is secured to the mounting part of the fixing component.

[0021] The beneficial effects of this application are as follows: 1. This application reduces the complex linkage structure of traditional mechanical switches by rotating the trigger and fixing parts together with the triggering method of micro switches, thereby reducing the risk of wear of parts and improving overall reliability;

[0022] 2. The operating component of this application drives the trigger component to rotate around the fastener as a pivot, so that the trigger part can accurately press or release the micro switch, ensuring rapid switching of the switch state and improving control sensitivity.

[0023] Another technical solution adopted in this application is: providing a power head, comprising:

[0024] case;

[0025] The motor is housed within the casing;

[0026] The aforementioned switch assembly is housed within the housing;

[0027] The micro switch is electrically connected to the motor.

[0028] The rotation triggering mechanism of the switch assembly enables rapid and precise control of the micro switch, thereby achieving instant start / stop or speed adjustment of the motor and improving the operating response speed and control precision of the power head.

[0029] The power head achieves more efficient, stable, and durable motor control through optimized switch assembly design, making it suitable for various power tools, garden machinery, and industrial equipment, with significant improvements in performance, safety, and user experience.

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1

[0039] Reference Figure 1This embodiment discloses a switch assembly 100, which includes a fixing member 10, a trigger member 30 rotatably connected to the fixing member 10 by a fastener 20, a micro switch 40 disposed on one side of the trigger member 30, and an operating member 50 connected at one end to the trigger member 30. When the operating member 50 is touched, the operating member 50 can drive the trigger member 30 to rotate relative to the fixing member 10 with the fastener 20 as the pivot, thereby touching the micro switch 40. The fastener 20 can be implemented as a screw.

[0040] Furthermore, an elastic element 60 is connected between the trigger element 30 and the fixing element 10. When the operating element 50 drives the trigger element 30 to rotate relative to the fixing element 10, the deformed elastic element 60 can drive the trigger element 30 to reset.

[0041] Specifically, refer to Figure 4 In this embodiment, the trigger 30 includes a connecting part 301, a rotating part 302, a triggering part 303, and a supporting part 304, and the fixing part 10 includes a main body part 101, a mounting part 102, and a fixing part 103.

[0042] The rotating part 302 of the trigger 30 is rotatably connected to the main body 101 of the fixing part 10 via the fastener 20. The fastener 20 forms a rotation pivot. An elastic member 60 is connected between the support part 304 and the fixing part 103. The operating member 50 passes through the mounting part 102 and is connected to the connecting part 301. When the operating member 50 drives the trigger 30 to rotate relative to the fixing part 10, the trigger part 303 moves closer to or further away from the micro switch 40.

[0043] In this embodiment, the elastic element 60 is preferably a spring, and the edges of the support part 304 and the fixing part 103 are provided with grooves 70. The two ends of the elastic element 60 are respectively engaged with the grooves 70 on the edges of the support part 304 and the fixing part 103.

[0044] In addition, to adapt to the starting requirements of different garden tools, there are one or more micro switches 40. The micro switches 40 are mounted on the fixing part 103 of the fixing part 10. The surface and / or back of the fixing part 103 provides the mounting area for the micro switches 40. The micro switches 40 are fixed to the surface and / or back of the fixing part 103 by screws. The micro switches 40 have a contact 401 and are electrically connected to the motor. The actual setting of the micro switches 40 is as follows: when the contact 401 is pressed, the micro switches 40 are in the open state and the motor is off; when the contact 401 is reset, the micro switches 40 are in the closed state and the motor is on.

[0045] Reference Figure 2 , Figure 3When the switch assembly 100 of this application is in use, by pulling the operating member 50, the trigger member 30 can be driven to rotate relative to the fixing member 10 with the fastener 20 as the pivot, thereby realizing the opening and closing control of the micro switch 40. The trigger part 303 of the trigger member 30 has a first position close to the micro switch 40 and a second position away from the micro switch 40. When the trigger part 303 is in the first position, the trigger part 303 approaches and presses the contact piece 401 of the micro switch 40. At this time, the micro switch 40 is in the open state and the motor is turned off.

[0046] When the operating member 50 is pulled, the trigger member 30 rotates relative to the fixing member 10 with the fastener 20 as the pivot. When the operating member 50 is pulled into place, the trigger part 303 is in the second position. At this time, the trigger part 303 is away from the contact piece 401 of the micro switch 40. The contact piece 401 is in the reset state, the micro switch 40 is in the conducting state, and the motor is turned on.

[0047] Additionally, it should be noted that, in order to achieve precise on / off control of the micro switch 40, the operating element 50 can be configured as a throttle control line. Specifically, the operating element 50 can be configured to be directly connected to the connection part 301 of the trigger element 30 by a cable, with the other end of the operating element 50 extending to the operating area of ​​the garden tool, thereby facilitating remote control of the on / off of the micro switch 40.

[0048] Throttle control wires are typically installed on fuel-powered garden tools. In actual use, users can disassemble and install the fuel-powered garden tool, directly connecting the throttle control wire to the switch assembly 100 of this application. Since the switch assembly 100 of this application is mainly used to control the opening and closing of the electric motor, by directly connecting the throttle control wire of the fuel-powered garden tool to the switch assembly 100 of this application, the garden tool can be switched from fuel-powered to electric-powered.

[0049] When the operating element 50 is set as a throttle control line, a protective sleeve 501 can be fitted over the outside of the operating element 50. The protective sleeve 501 protects the internal operating element 50. Moreover, one end of the protective sleeve 501 can be directly engaged with the mounting part 102 of the fixing element 10 through the opening groove. The protective sleeve 501 can be stably supported on the fixing element 10.

[0050] In summary, this application reduces the complex linkage structure of traditional mechanical switches, lowers the risk of component wear, and improves overall reliability by using the rotational engagement of the trigger element 30 and the fixing element 10, combined with the triggering method of the micro switch 40.

[0051] The operating component 50 of this application drives the trigger component 30 to rotate around the fastener 20, so that the trigger part 303 can accurately press or release the micro switch 40, ensuring rapid switching of the switch state and improving control sensitivity.

[0052] Example 2

[0053] Reference Figure 5 , Figure 6 This embodiment discloses a power head 200, which includes a housing 201 and a motor 202 disposed within the housing 201. Additionally, the power head 200 also includes a switch assembly 100 as described in the previous embodiment. A microswitch 40 in the switch assembly 100 is electrically connected to the motor 202. The housing 201 directly covers the outside of the motor 202 and the switch assembly 100. One side of the housing 201 has an opening 203. The connecting portion 301 and the mounting portion 102 of the switch assembly 100 extend from the opening 203. The opening 203 provides the space required for the connecting portion 301 to swing. An operating member 50 connected to the connecting portion 301 is located directly outside the housing 201. The power head 200 of this embodiment is mainly used in power tools and garden tools to provide the power required for their operation.

[0054] The power head 200 of this application can quickly and accurately control the on / off state of the micro switch 40 through the rotation trigger mechanism of the switch assembly 100, thereby realizing the instant start / stop or speed adjustment of the motor 202 and improving the operation response speed and control precision of the power head.

[0055] The Power Head 200 achieves more efficient, stable, and durable motor control through optimized switch assembly design. It is suitable for various power tools, garden machinery, and industrial equipment, and offers significant improvements in performance, safety, and user experience.
