DETAILED DESCRIPTION
[0041] The following will be described in detail below with reference to the accompanying drawings. Figures 1-14 The present application will be further described in detail.
[0042] Embodiment:
[0043] The embodiment of the present application discloses a dustproof and waterproof brushless signal switch. Figures 1-5 A dustproof and waterproof brushless signal switch, comprising a base 1 and an upper cover 2 arranged on the base 1, a push rod 3 slidingly arranged on one side of the base 1, a through hole 11 formed in the base 1 for the push rod 3 to pass through, and a mounting protrusion 12 integrally formed on the through hole 11 of the base 1.
[0044] Through the arrangement of the mounting protrusion 12, the push rod 3 can be conveniently mounted on the base 1, the through hole 11 and the mounting protrusion 12 are integrally formed on the base 1, the first mounting groove 121 is arranged on the mounting protrusion 12, the second mounting groove 31 is arranged on the push rod 3, and the dustproof ring with the telescopic property can shield and protect the push rod 3 exposed outside the base 1, thereby ensuring good dustproof and waterproof effects.
[0045] Referring to Figure 1 andFigures 3-4 The junction of the base 1 and the upper cover 2 is provided with a wire outlet 22 for leading out the internal lead, and the wire outlet 22 is filled with waterproof glue. In order to further improve the overall sealing of the signal switch and improve the dustproof and waterproof effect, the side of the upper cover 2 close to the base 1 is provided with a sealing groove 21 for embedding the side of the base 1, and the groove wall of the sealing groove 21 is provided with a waterproof glue layer at the contact surface with the base 1. In this embodiment, the waterproof glue and the waterproof glue layer are made of 704 silicone.
[0046] Referring to Figure 2 and Figures 5-9 The base 1 is provided with a circuit board 4 and an auxiliary on-off unit 5, the auxiliary on-off unit 5 includes a moving contact frame 51, an on-off brush 52 and a conduction band 53, the moving contact frame 51 is connected with the end of the push rod 3 extending into the base 1, and the end of the push rod 3 penetrating out of the base 1 is fixedly connected with a trigger 33 in a plug-in manner. The inner wall of the base 1 is integrally formed with a guide rib 13, the back of the moving contact frame 51 is provided with a guide sliding groove 511 matched with the guide rib 13, the on-off brush 52 is installed on one side of the moving contact frame 51, and the conduction band 53 is fixed to the second plate surface of the circuit board 4; when the trigger 33 is in a natural state, the on-off brush 52 and the conduction band 53 are in a disconnected state; when the trigger 33 is in a pressed state, the on-off brush 52 is in conduction with one of the points on the conduction band 53.
[0047] When the trigger 33 is pressed inward during use of the signal switch, the trigger 33 drives the push rod 3 and the moving contact frame 51 to move inward together. The on-off brush 52 on the moving contact frame 51 corresponds to the conduction band 53 on the circuit board 4. During the pressing process, the auxiliary switch is switched from the disconnected state to the closed state with the displacement of the on-off brush 52.
[0048] Referring to Figure 5 and Figure 9 In order to facilitate the installation of the moving contact frame 51 and the push rod 3, the back of the moving contact frame 51 is integrally formed with a limiting buckle 512, and the outer circumferential surface of the push rod 3 is provided with a limiting clamping groove 34 matched with the limiting buckle 512.
[0049] Referring to Figure 2 and Figure 5 The base 1 is provided with an elastic reset assembly 14, the elastic reset assembly 14 includes a spring column 141 installed in the base 1 and a compression spring 142 sleeved on the spring column 141, the end of the moving contact frame 51 away from the push rod 3 is provided with a spring accommodating groove 514, the other end of the spring column 141 is fixedly provided with a limiting portion 1411, one end of the compression spring 142 abuts against the limiting portion 1411, and the other end is arranged in the spring accommodating groove 514. In this way, when the trigger 33 is pressed, the push rod 3 and the moving contact frame 51 are driven to move inward, and the compression spring 142 is compressed to store energy; after the trigger 33 is released, the compression spring 142 releases the energy to drive the trigger 33 to reset, thereby facilitating the trigger 33 to control the movement of the signal switch.
[0050] With reference to Figure 2 , Figures 6-7 and Figure 10 , the base 1 is further provided with a speed regulating unit 6, which comprises a linear Hall element 61 fixed to the first plate surface of the circuit board 4 and a Hall element triggering assembly comprising a magnet mounting seat 62 and first and second magnets 63 and 64 mounted side by side on the magnet mounting seat 62, the first and second magnets 63 and 64 being oppositely installed and arranged. The magnet mounting seat 62 is connected to the moving contact frame 51. In this embodiment, the first magnet 63 is located at the outer side of the second magnet 64.
[0051] With reference to Figure 2 , Figure 6 and Figure 10 , the side wall of the moving contact frame 51 is integrally formed with a mounting protrusion 513, the circuit board 4 is provided with a relief hole 41, which is strip-shaped and arranged in the horizontal direction, and the magnet mounting seat 62 is arranged on the side of the circuit board 4 away from the moving contact frame 51, and the magnet mounting seat 62 is provided with a mounting hole 621, and the mounting protrusion 513 is connected to the mounting hole 621 in a fitting manner after passing through the relief hole 41.
[0052] When the trigger 33 is in the natural state, the second magnet 64 is directly opposite the linear Hall element 61, and the linear Hall element 61 does not output a speed regulating signal at this time. When the trigger 33 is in the pressed state and is gradually pressed, the moving contact frame 51 is driven to move inward, the moving contact frame 51 drives the magnet mounting seat 62 to move, and in turn drives the first and second magnets 63 and 64 to move inward, the distance between the first and second magnets 63 and 64 and the linear Hall element 61 gradually changes, and in turn the output voltage of the linear Hall element 61 gradually changes, so as to facilitate the realization of the speed regulating function. The signal switch does not need to use a brush structure to realize the switching speed regulation, and does not need to be in contact with the circuit board 4 during the speed regulating operation, thereby reducing the wear of the circuit board 4 and being beneficial to prolonging the service life of the switch.
[0053] With reference to Figure 2 , Figure 8 and Figures 11-12 , the signal switch further comprises a reversing unit 7, which comprises a reversing driving member that can be actuated, a reversing mounting seat 73 that is arranged in the base 1 in a sliding manner in the horizontal direction and is driven by the reversing driving member to move, and a reversing signal output module arranged on the reversing mounting seat 73 and cooperated with the circuit board 4. The reversing signal output module comprises a reversing brush 74 mounted on the reversing mounting seat 73 and two reversely arranged reversing signal bands 75 fixed to the second plate surface of the circuit board 4 and corresponding to the reversing brush 74.
[0054] With reference to Figures 2-3 andFigures 11-14 The reversing driving member comprises a reversing lever 71 and a reversing limiting block 72. One end of the reversing lever 71 is integrally formed with a mounting shaft portion 711. The reversing lever 71 is rotatably mounted on the base 1 through the mounting shaft portion 711. An installation shaft hole 15 matching the mounting shaft portion 711 is formed in the upper side of the base 1. A plurality of rotation limiting protrusions 712 are integrally formed on the bottom surface of the mounting shaft portion 711. A rotation limiting groove 721 matching the rotation limiting protrusions 712 is formed in one end of the reversing limiting block 72. The reversing limiting block 72 is connected with the base 1 through the mounting shaft portion 711 and the self-tapping screw 76. An installation groove 725 is formed in the other end of the reversing limiting block 72. A reversing elastic member 722 is installed in the installation groove 725. A ball 723 is arranged on the end of the reversing elastic member 722 away from the bottom wall of the installation groove 725. A plurality of reversing limiting grooves 16 are formed in the inner wall of the base 1. One end of the ball 723 is located in the installation groove 725, and the other end is embedded in one of the reversing limiting grooves 16. When the reversing elastic member 722 is compressed, the ball 723 can move from one of the reversing limiting grooves 16 to another. A guide arc groove 724 is formed in the bottom surface of the reversing limiting block 72. A reversing protrusion 731 is integrally formed on one side of the reversing mounting seat 73 close to the reversing limiting block 72. The end of the reversing protrusion 731 away from the reversing mounting seat 73 is slidably arranged in the guide arc groove 724. In this embodiment, the rotation limiting protrusions 712 are provided with two; the reversing elastic member 722 is a compression spring; and the reversing limiting grooves 16 are provided with three, corresponding to the three reversing positions of the signal switch.
[0055] When the signal switch is used, the reversing lever 71 is used to give different reversing signals to the switch through different positions of the left, middle and right, so as to control the forward / reverse rotation of the whole machine. The specific operation of reversing is as follows: when the reversing lever 71 is actuated, the reversing limiting block 72 is driven to rotate. The reversing protrusion 731 is arranged in the guide arc groove 724 of the reversing limiting block 72, and the reversing mounting seat 73 is limited in part of the freedom, and can only move left and right. The reversing mounting seat 73 drives the reversing brush 74 to move left and right. The reversing brush 74 corresponds to two spaced reversing signal belts 75, one of which is used to output the forward rotation signal, and the other is used to output the reverse rotation signal. The left and right movement of the reversing brush 74 makes the circuit board 4 output different signals, so as to control the forward / reverse rotation of the whole machine, and realize the function of reversing.
