Description

Technical Field

[0001] The invention relates to a switch component and an electric tool, belonging to the technical field of garden tools. Background Art

[0002] At present, electric tools usually have a start switch on the handle that the user grasps. However, when using the electric tool, the user may accidentally press the start switch when the user only needs to hold the electric tool instead of using it, causing the electric tool to start by mistake, thereby posing a safety hazard. For this reason, it is necessary to provide a safety switch on the electric tool to prevent the switch component from accidentally starting when the user does not need the electric tool to work.

[0003] Conventional start switches are usually located below the handle and facing downward. When using an electric tool, the user can start the electric tool by pressing the start switch upward while holding the handle. Existing safety switches are mainly linkage type, that is, if the start switch needs to be activated, the user must first press, push or rotate the safety switch. At this time, the safety switch unlocks the start switch, and the user can then activate the start switch to start the tool. Switch assemblies designed based on the above technology are widely used in the field of electric tools, among which grip-type switch assemblies are the most common. The safety switch of this type of switch assembly is located above the handle opposite to the start switch and facing upward. When the user uses it, the user can press the safety switch and then press the start switch by holding the tool handle. Therefore, this type of grip switch has a simple structure and is easy to use, making it widely used in the field of electric tools.

[0004] However, the above-mentioned grip-type switch assembly has the defect of not being able to significantly distinguish between the action of activating the safety switch and the action of actuating the starting switch when in use, which may lead to the mistaken actuation of the starting switch and thus cause a dangerous situation. Under the new safety regulations for the use of tools, the potential unsafe factors of such grip-type switch assemblies limit their future application in tools.

[0005] In view of this, it is indeed necessary to propose improvements to the existing safety switches to solve the above problems. Summary of the invention

[0046] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1 As shown, the present invention discloses an electric tool, which can be an electric tool such as a pruner, an electric saw, a hair dryer, a chain saw or a mower, or other types of handheld electric tools, and these electric tools can all be operated by using the switch assembly 10 of the present invention, without limitation herein. These electric tools generally include an operating assembly, a driving assembly, a battery assembly and a switch assembly 10, wherein the operating assembly is used to realize the functions of the electric tool, such as mowing, blowing, etc.; the driving assembly is connected to the operating assembly and is used to drive the operating assembly to move, and the driving assembly is generally a motor; the battery assembly is used to power the driving assembly; and the switch assembly 10 is used to start or shut down the electric tool (including the driving assembly and the battery assembly).

[0048] The switch assembly of the present invention extends along the longitudinal axis and is arranged in the shape of a grippable handle for user operation. Since there are many types of applicable electric tools, the specific structure of the electric tools is not limited here. The following description will mainly describe the specific structure of the switch assembly and the activation method in detail.

[0049] like Figure 2 and Figure 3As shown, the switch assembly 10 includes a housing 11, a main switch 12 accommodated in the housing 11, and a start switch 13 and a lock switch 14 installed on the housing 11, one end of the lock switch 14 is exposed outside the housing 11, and the other end is in contact with the start switch 13, and one end of the start switch 13 is also exposed outside the housing 11, and the other end is accommodated in the housing 11 and in contact with the main switch 12. The start switch 13 is rotatably connected to the housing 11 through a pivot 115, and the pivot 115 is perpendicular to the longitudinal axis; the lock switch 14 is slidably connected to the housing 11 to move between a locking position and a release position. The sliding direction of the lock switch 14 forms an angle with the longitudinal axis, and the angle is set to be between 0° and 60°, preferably between 0° and 45°, more preferably between 0° and 30°, and more preferably between 0° and 15°, so that the operator can apply force easily and conform to ergonomic design. In this embodiment, the sliding direction of the lock switch 14 is parallel to the longitudinal axis, and the angle is 0°. In this way, the operation action of the start switch 13 is clearly distinguished from the operation action of the lock switch 14 , which is not only convenient for the operator to operate in terms of ergonomics, but also can avoid mis-actuation of the start switch 13 .

[0050] Preferably, in order to make the space of the switch assembly 10 smaller, the start switch 13 is arranged on the first side of the housing 11, the lock switch 14 is located on the second side of the housing 11, and the start switch 13 and the lock switch 14 are arranged relative to each other about the longitudinal axis. The main switch 12 is arranged at the front end of the housing 11 and is located on the second side of the housing 11. When in the locked position, the lock switch 14 abuts against the start switch 13 to prevent the start switch 13 from rotating; when in the released position, the lock switch 14 is disengaged from the start switch 13, allowing the start switch 13 to be operated to rotate to trigger the main switch 12, so that the main switch 12 is turned on, and then the motor (not shown) is controlled to start or turn off.

[0051] like Figure 2 and Figure 4 As shown, the housing 11 is formed by assembling two housings, and the main switch 12 is accommodated in the accommodation space 111 formed by the two housings. Taking the first housing 112 as an example, the installation of the main switch 12, the start switch 13 and the lock switch 14 in the housing is shown in detail.

[0052] A fixing portion 113 is provided on the inner side wall of the first housing 112, and a receiving groove 114 communicating with the receiving space 111 is provided in the fixing portion 113, and the main control switch 12 is received in the receiving groove 114. A pivot 115 and a boss 116 are also provided on the inner side wall of the first housing 112, which are used to connect the start switch 13 and the lock switch 14 to the first housing 112 respectively. The pivot 115 and the boss 116 are mounted or integrally formed on the first housing 112, and the pivot 115 and the boss 116 can both be configured to be columnar, preferably cylindrical. Specifically, the start switch 13 passes through the pivot 115 and can rotate along a vertical plane relative to the pivot 115; the lock switch 14 passes through the boss 116 and can move forward and backward relative to the boss 116 in a direction parallel to the longitudinal axis.

[0053] A handle portion 110 is formed on the housing 11 for a user to hold to operate the switch assembly 10. In order to make the handle portion 110 easy for an operator to hold, the start switch 13 is located at the bottom of the handle portion 110 and partially protrudes from the handle portion 110, and the lock switch 14 is located at the top of the handle portion 110 and partially protrudes from the handle portion 110. With such a design, when starting the switch assembly 10, the user can directly hold the handle portion 110, push the lock switch 14 forward, and then press the start switch 13 upward with the index finger to start the main control switch 12, which is easy to operate.

[0054] like Figure 3 and Figure 8 As shown, the main control switch 12 is set in a push-type configuration, including a main body 121 and a telescopic arm 122 connected to the main body 121, and the telescopic arm 122 is elastically configured so that it can reset itself after being released from the pressing. In the embodiment of the present invention, the main control switch 12 is a micro switch, and one end of the start switch 13 is located behind the telescopic arm 122, so that the start switch 13 is used to trigger (press) the telescopic arm 122 to turn on the main control switch 12.

[0055] like Figure 4 and Figure 5 As shown, the start switch 13 includes a contact portion 131 in contact with the telescopic arm 122 of the main switch 12, a second operating portion 132 protruding from the bottom of the housing 11, and an intermediate portion 133 connecting the contact portion 131 and the second operating portion 132, wherein the second operating portion 132 is located at the first end 130 of the start switch 13, and the contact portion 131 is located at the second end 130' of the start switch 13. The intermediate portion 133 is mounted on the pivot 115, so that the start switch 13 can rotate relative to the housing 11, so that when the operator holds the second operating portion 132 tightly, the contact portion 131 can be synchronously driven to press the telescopic arm 122 of the main switch 12 forward to turn on the main switch 12.

[0056] The contact portion 131 is located at the rear side of the telescopic arm 122, and the surface where the contact portion 131 contacts the telescopic arm 122 is a flat surface, so that when the second operating portion 132 is gripped, the contact portion 131 can be synchronously driven to press the telescopic arm 122 of the main switch 12 forward, so that the main switch 12 is stably turned on. The middle portion 133 is circularly arranged to facilitate rotation in the housing 11; the middle portion 133 is provided with a connecting hole 134 for the pivot 115 to pass through, preferably, the connecting hole 134 is a circular through hole, and the diameter is slightly larger than the diameter of the pivot 115, so as to facilitate the starter switch 13 to rotate around the pivot 115.

[0057] The second operating portion 132 of the start switch 13 is provided with a receiving cavity 135, so that the second operating portion 132 is formed with a first side wall 136, a second side wall 137 and a third side wall 139, and the receiving cavity 135 is located between the first side wall 136, the second side wall 137 and the third side wall 139; in other words, the receiving cavity 135 is formed by being recessed downward from the top of the second operating portion 132. The rear end of the second operating portion 132 is provided with an end surface 138 for contacting the locking switch 14 in the locked state, and preferably, the end surface 138 and the upper surface of the second operating portion 132 are located in the same plane.

[0058] The start switch 13 also includes a first elastic member (not shown), one end of which is fixed to the middle portion 133 and the other end is fixed to the inner wall of the first housing 112, so that after the second operating portion 132 is gripped, the first elastic member is compressed and the contact portion 131 presses the telescopic arm 122 of the main switch 12 forward, so that the main switch 12 is turned on and the motor is started; and after the second operating portion 132 is released, the start switch 13 as a whole will return to the initial position under the action of the restoring force of the first elastic member, at which time the contact portion 131 is separated from the telescopic arm 122 of the main switch 12, so that the main switch 12 is turned off and the current of the motor is cut off. In this embodiment, the first elastic member is a compression spring, which is mainly used to drive the start switch 13 to reset; of course, other components that can also achieve the reset function can also be used to replace the first elastic member, which is not limited here.

[0059] like Figure 6 and Figure 7 As shown, the locking switch 14 is mounted on the top of the housing 11 and can move relative to the housing 11 in a direction parallel to the longitudinal axis. The locking switch 14 includes a first operating portion 141 protruding from the top of the housing 11, an abutting portion 142 in contact with the start switch 13, and a main body 143 connecting the first operating portion 141 and the abutting portion 142. The main body 143 is mounted on the boss 116 so that the main body 143 can move relative to the housing 11 in the direction of the longitudinal axis, so that when the first operating portion 141 is pushed to move in a direction parallel to the longitudinal axis, the abutting portion 142 can be driven to move in a direction parallel to the longitudinal axis simultaneously.

[0060] The first operating portion 141 includes a first operating surface 140 extending in a direction parallel to the longitudinal axis and a second operating surface 144 located at the front end of the first operating surface 140 (close to the main switch 12), and the second operating surface 144 is configured to form an angle with the longitudinal axis and has an increased width in a direction perpendicular to the longitudinal axis relative to the first operating surface 140, so that the operator can push the main body 143 to slide forward in a direction parallel to the longitudinal axis through the first operating surface 140 and the second operating surface 144, so that the operator can apply thrust. Of course, a surface texture or other structure for increasing friction can also be added to the outer surface of the first operating portion 141 to facilitate the operator to apply horizontal thrust.

[0061] The abutting portion 142 and the main body 143 are both received in the housing 11 and extend from the bottom of the first operating portion 141 toward the start switch 13. In this embodiment, the abutting portion 142 extends downward in the vertical direction and is used to abut the start switch 13 in the vertical direction. The front end of the main body 143 is provided with a slide groove 145 for the boss 116 to pass through. The slide groove 145 extends in a direction parallel to the longitudinal axis. When the first operating portion 141 is pushed to move, the boss 116 can slide along the slide groove 145. Of course, the slide groove 145 can also be used to limit the moving distance of the locking switch 14.

[0062] The locking switch 14 further includes a second elastic member 146, one end of which is fixed to the main body 143 and the other end is fixed to the first housing 112, so that when the locking switch 14 moves in a direction parallel to the longitudinal axis, the second elastic member 146 switches between a stretched state and a released state. Preferably, an "I"-shaped limiting groove 147 is provided on the main body 143 for fixing one end of the second elastic member 146 on the main body 143.

[0063] In this embodiment, the second elastic member 146 and the slide groove 145 are respectively located at the two ends of the main body 143, and the slide groove 145 is arranged at the end of the main body 143 close to the main control switch 12 (i.e., the front end), and the second elastic member 146 is arranged at the end of the main body 143 away from the main control switch 12 (i.e., the rear end), so that after pushing the first operating part 141, the second elastic member 146 is stretched; and after releasing the first operating part 141, the locking switch 14 as a whole will return to the initial position (i.e., the locking position) under the action of the restoring force of the second elastic member 146.

[0064] In this embodiment, the second elastic member 146 is a coil spring, which is mainly used to drive the lock switch 14 to reset; of course, other components that can also achieve the reset function can also be used to replace the second elastic member 146, which is not limited here. In addition, the second elastic member 146 can also be arranged on the side of the main body 143 close to the main switch 12 (i.e., the front end), in which case the lock switch 14 can also be reset, which will not be described in detail here.

[0065] In this embodiment, the main switch 12 is located at the front end of the shell 11. When the locking switch 14 is in the locking position, the distance between the locking switch 14 and the main switch 12 is defined as a first distance. When the locking switch 14 is in the releasing position, the distance between the locking switch 14 and the main switch 12 is defined as a second distance. The first distance is greater than the second distance.

[0066] It should be noted that: when the locking switch 14 is in the locking position, the contact portion 142 contacts the end surface 138 of the second operating portion 132, and the start switch 13 is in a locked state. When the locking switch 14 is switched from the locking position to the release position, it is only necessary to apply a thrust to the first operating portion 141 so that the first operating portion 141 as a whole moves horizontally toward the side of the main control switch 12. At this time, the contact portion 142 will move synchronously driven by the first operating portion 141 until the contact portion 142 is located above the receiving cavity 135 and is out of contact with the end surface 138 of the second operating portion 132. At this time, the locking switch 14 is immediately released from the locking of the start switch 13, the locking switch 14 is in the release position, and the start switch 13 is in a released state. Before the second operating portion 132 is operated, the contact portion 142 is located outside the receiving cavity 135. After the second operating portion 132 is operated, the contact portion 142 protrudes and is received in the receiving cavity 135. At this time, the contact portion 131 can trigger the telescopic arm 122 of the main switch 12 to turn on the main switch 12. If continuous pressure is applied to the second operating portion 132 to keep the main switch 12 turned on, the third side wall 139 at the rear end of the receiving cavity 135 can keep the locking switch 14 in the released position, so that the user only needs to apply a gripping force to keep the power tool working, thereby improving the user experience.

[0067] The starting method of the switch assembly 10 mainly includes the following steps:

[0068] S1, applying a thrust to the locking switch 14 in a direction parallel to the longitudinal axis until the locking switch 14 moves from the locking position to the releasing position, so that the locking switch 14 is out of contact with the starting switch 13, thereby releasing the restriction of the locking switch 14 on the starting switch 13;

[0069] S2. Operate (i.e., squeeze upward) the second operating portion 132 (i.e., the first end 130) of the start switch 13 to rotate the start switch 13 relative to the housing 11 around the pivot 115 until the contact portion 131 (i.e., the second end 130') of the start switch 13 triggers the main switch 12, and the main switch 12 is turned on.

[0070] Specifically: Figure 3In the initial state shown, the locking switch 14 is in the locking position, and the abutment portion 142 of the locking switch 14 abuts against the end face 138 of the second operating portion 132 in the vertical direction, thereby limiting the rotation of the starting switch 13 around the pivot 115; in this case, even if the locking switch 14 and / or the starting switch 13 are accidentally touched, the main control switch 12 cannot be turned on, and the power tool remains in a non-use state.

[0071] When the power tool needs to be used, first, a horizontal thrust is applied to the first operating part 141 to make the first operating part 141 move horizontally as a whole toward the side of the main switch 12. At this time, the abutment part 142 will move synchronously driven by the first operating part 141 until the abutment part 142 is out of contact with the end face 138. At this time, the second elastic member 146 is stretched and deformed, and the locking switch 14 is switched from the locked position to the released position; then, the second operating part 132 is pressed upward (gripped) to make the start switch 13 rotate as a whole relative to the housing 11 until the contact part 131 triggers the telescopic arm 122 to turn on the main switch 12. At this time, the motor starts to rotate and the power tool starts to work normally.

[0072] After use, the locking switch 14 and the starting switch 13 are released at the same time, and the starting switch 13 will return to its initial state under the restoring force of the telescopic arm 122 and the first elastic member; at the same time, under the elastic force of the second elastic member 146, the locking switch 14 moves backward as a whole until the abutting portion 142 abuts against the end face 138 of the second operating portion 132 again, and the locking switch 14 is in the locked position again.

[0073] In summary, when the switch assembly 10 of the present invention is not in use, the mutual contact between the start switch 13 and the lock switch 14 can be used to make the lock switch 14 in the locked position and the start switch 13 in the locked state. At this time, the main switch 12 cannot be started and the power tool remains in the non-use state; when starting normally, the lock switch 14 is first pushed horizontally until the lock switch 14 and the start switch 13 are released from contact. At this time, the main switch 12 can be started by pressing the start switch 13 again, so that the power tool works normally. Compared with the prior art, the present invention is not only simple in structure and easy to operate, but also the switch assembly 10 is always in the locked state when not in use, and will not cause abnormal start due to accidental pressing, which can avoid mis-actuation of the start switch 13 and has a high safety factor.

[0074] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
