Description

Technical Field

[0001] This disclosure relates to a trigger switch, and more particularly to a trigger switch with a restart protection function. Background Technology

[0002] Currently, the switching functions of medium-sized angle grinders on the market are basically similar, but they have the following functional defects:

[0003] 1. The commonly used switches for medium-sized angle grinders are generally mechanical switches. The switch achieves the closing and locking function through a locking button. After the switch is locked, if the medium-sized angle grinder is accidentally de-energized, it will start immediately after the power is restored. This does not comply with the GB15093.1 standard and poses a major safety hazard.

[0004] 2. The commonly used medium-sized angle grinder switch is a mechanical switch without a soft start function. When the switch is turned on, the medium-sized angle grinder switch will vibrate due to inertia. If it is not held firmly, it is easy to fall, which also poses a significant safety hazard.

[0005] 3. Commonly used medium-sized angle grinder switches are sometimes a combination of a mechanical switch and a controller. This results in more wiring and a more complex assembly process, which makes the production of medium-sized angle grinders more difficult.

[0006] Therefore, it is imperative to design a trigger switch with a restart protection function. Utility Model Content

Detailed Implementation

[0044] The present disclosure will now be described in detail with reference to the embodiments and accompanying drawings. It should be noted that the described embodiments are only intended to facilitate understanding of the present disclosure and do not constitute any limitation thereof. The orientations used in this application, such as up, down, left, and right, are used for convenience in describing the description with reference to the accompanying drawings and do not constitute a limitation on the scope of protection.

[0045] like Figures 1-9 As shown, this embodiment of the present disclosure provides a trigger switch with a restart protection function, including: a base body 1, a top cover 2, a push shaft 3, a reset spring 4, and a circuit board assembly 5. One end of the push shaft 3 extends out of the housing formed by the base body 1 and the top cover 2, and a trigger 6 is provided at the end of the push shaft 3 extending out of the housing.

Furthermore, the locking block structure 8 includes a locking button top block 81 and a locking button hook 82, both of which engage with the locking button 71. It should be noted that the first fastener can be a rivet.

[0048] In this embodiment, by setting a locking structure on the trigger and a locking block structure on the upper cover, after the switch is turned on, the locking button 71 is first moved and then the trigger 6 is released, so that the tail hook 712 on the locking button 71 and the locking button hook 82 on the upper cover 2 engage with each other, and the trigger 6 cannot be reset, thus the switch achieves the closed locking function.

[0049] like Figures 3-7 As shown, the connection structure 9 includes a moving contact assembly 91, a stationary contact assembly 92 that cooperates with the moving contact assembly 91, a moving contact bracket 93 that fixes the moving contact assembly 91, and a contact spring assembly 94 that electrically connects the moving contact bracket 93 to the circuit board assembly 5. The stationary contact assembly 92, the moving contact bracket 93, and the contact spring assembly 94 are all disposed on the base body 1. The connection structure 9 also includes a connecting piece 95 and an output piece 96 disposed on the base body 1. A connecting piece connecting post 951 is provided on the connecting piece 95 so that the connecting piece 95 is electrically connected to the circuit board assembly 5 through the connecting piece connecting post 951. At the same time, an output piece connecting post 961 is provided on the output piece 96 so that the output piece 96 is electrically connected to the circuit board assembly 5 through the output piece connecting post 961.

[0050] like Figures 5-7As shown, the moving contact assembly 91 includes a rotating block 911, a driving spring 912, a moving contact 913, and a moving contact 914. A push shaft groove 31 is provided at one end of the push shaft 3 within the housing, and a rotating block connector 9111 is provided at one end of the rotating block 911. The rotating block 911 is connected to the push shaft 3 through the engagement of the rotating block connector 9111 with the push shaft groove 31. A rotating block hook 9112 is provided at the other end of the rotating block 911, and a spring first slot 9121 is provided at one end of the driving spring 912. The driving spring 912 is connected to the rotating block 911 through the engagement of the rotating block hook 9112 with the spring first slot 9121. A spring second slot is provided at the other end of the driving spring 912. The groove 9122 has a moving contact connector 9131 at one end of the moving contact 913. The other end of the driving spring 912 is connected to the moving contact 913 through the cooperation of the second slot 9122 of the spring and the moving contact connector 9131. A moving contact connecting block 9132 is provided at the other end of the moving contact 913, and a moving contact connecting groove 9133 is provided on the moving contact connecting block 9132. At the same time, a bracket connector 931 is provided on the moving contact bracket 93, and a bracket connecting hole 932 is provided on the bracket connector 931, so that the moving contact connecting block 9132 passes through the bracket connecting hole 932 and is connected to the bottom of the rotating block 911 through the moving contact connecting groove 9133. The moving contact 914 is provided at the bottom of the end of the moving contact 913 that is connected to the driving spring 912.

[0051] In this embodiment, after pressing the trigger 6, the trigger 6 can drive the push shaft 3 to move downward. The push shaft 3 drives the tail of the rotating block 911, thereby causing the rotating block 911 to make a clockwise rocker motion, so that the right side of the drive spring 912 tilts upward. When the drive spring 912 tilts to a certain height, the left side of the drive spring 912 will press down on the head of the moving contact 913 instantly, so that the moving contact 914 and the stationary contact 924 make contact, realizing the instantaneous connection function of the switch.

[0052] like Figure 5 As shown, the stationary contact assembly 92 includes a first terminal 921, a second terminal 922, a stationary contact 923, and a stationary contact 924. The first terminal 921 is connected to the connecting piece 95, the second terminal 922 is connected to the stationary contact 923, and the stationary contact 924 is disposed on the stationary contact 923 so that the stationary contact 924 cooperates with the moving contact 914.

[0053] like Figure 5 As shown, by configuring the static contact assembly 92 to also include a screw fixing plate 925, the first terminal 921 and the second terminal 922 are both fixed to the base body 1 by the screw fixing plate 925.

[0054] like Figure 5As shown, the moving contact assembly 91 also includes an auxiliary spring 915, and a spring mounting hole group 9151 is provided on the auxiliary spring 915. Meanwhile, a bracket mounting hole group 933 is provided on the moving contact bracket 93, so that the second fastener 11 passes sequentially through the bracket mounting hole group 933 and the spring mounting hole group 9151 to connect the auxiliary spring 915 to the moving contact bracket 93. It should be noted that the second fastener 11 can be a screw.

[0055] like Figure 5 and Figure 8 and Figure 9 As shown, a base mounting groove 101 is provided on the base body 1 so that the first terminal 921 and the second terminal 922 are both disposed in the base mounting groove 101; a terminal mounting head 926 is provided on the top of the first terminal 921 and the second terminal 922, and a wiring hole 927 is provided on the connecting piece 95 and the stationary contact piece 923 so that the connecting piece 95 and the stationary contact piece 923 are respectively connected to the first terminal 921 and the second terminal 922 through the cooperation of the terminal mounting head 926 and the wiring hole 927.

[0056] like Figures 1-2 , Figure 5 As shown, a stepped sealing sleeve 12 is provided on the portion of the push shaft 3 extending out of the housing, and a top cover mounting platform 201 is provided on the top of the top cover 2, so that the stepped sealing sleeve 12 is connected to the top cover mounting platform 201, thereby achieving the dustproof function of the push shaft part. A first four-sided groove 102 and a second four-sided groove 103 are provided on the base body 1, and a first four-sided protrusion and a second four-sided protrusion are provided on the top cover 2, so that the first four-sided groove 102 of the base body and the first four-sided protrusion of the top cover form a first labyrinth interlocking structure, and the second four-sided groove 103 of the base body and the second four-sided protrusion of the top cover form a second labyrinth interlocking structure, thereby achieving the dustproof function between the base body and the top cover.

[0057] like Figure 5 As shown, by setting an upper cover connecting post 202 on the top of the upper cover 2 and a trigger connecting post on the bottom of the trigger 6, one end of the return spring 4 is connected to the upper cover connecting post 202, and the other end of the return spring 4 is connected to the trigger connecting post.

[0058] It should be noted that, as Figure 5 As shown, in this embodiment, a trigger fixing hole 62 is provided at the end of the trigger that does not have a locking structure, and a corresponding upper cover fixing platform 203 is provided on the upper cover. Fixing posts 204 are provided on both sides of the upper cover fixing platform 203. The trigger 7 is movably connected to the upper cover 2 by cooperating with the fixing posts 204 on the upper cover fixing platform 203 through the trigger fixing hole 73 on the trigger 7.

[0059] It needs to be further explained that, such as Figure 5 As shown, in this embodiment, a push shaft through hole 32 is provided at one end of the push shaft extending out of the housing, and a trigger slot is provided on the trigger 6. The pin 13 passes through the push shaft through hole and is engaged with the trigger slot to connect the push shaft to the trigger 6.

[0060] This disclosure provides a trigger switch with restart protection function, the operation of which is as follows:

[0061] Pressing the trigger 6 causes the push shaft 3 to move downwards. The push shaft 3 then drives the tail of the rotating block 911, causing the rotating block 911 to move clockwise like a rocker. This causes the right side of the drive spring 912 to tilt upwards. When the drive spring 912 tilts to a certain height, the left side of the drive spring 912 will instantly press down on the head of the moving contact 913, causing the moving contact 914 and the stationary contact 924 to make contact, thus realizing the instantaneous connection function of the switch.

[0062] After the switch is turned on, the locking button 71 is turned on and then the trigger 6 is released. The tail hook 712 on the locking button 71 and the locking button hook 82 on the upper cover 2 engage with each other, and the trigger 6 cannot be reset. The switch has achieved the closed locking function.

[0063] Pressing trigger 6 again resets the locking button 71 under the action of the locking button spring 72. When trigger 6 is released, it moves upward under the action of the return spring 4, which in turn drives the push shaft 3 to move upward. The push shaft 3 drives the tail of the rotating block 911, which in turn drives the rotating block 911 to make a counterclockwise rocker motion. This causes the right side of the drive spring 912 to tilt downward. When the drive spring 912 tilts to a certain height, the left side of the drive spring 912 will instantly pull up the head of the contact 913, causing the moving contact 914 and the stationary contact 924 to separate instantly, thus realizing the instantaneous disconnection function of the switch.

[0066] The input terminal of the switch 301 is connected to the first input terminal a and the second input terminal b, and its output terminal is connected to the first output terminal c and the first port of the current detection circuit 306.

[0067] The four input ports of the power failure detection circuit 302 are connected to the four ports of the switch 301, and its output port is connected to the first input port of the MCU minimum system 304.

[0068] The first and second ports of the MCU power supply circuit 303 are connected to the output terminal of the switch 301, and its output port is connected to the power input terminal of the MCU minimum system 304.
