Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and more specifically, to a switch mechanism and an electrical device. Background Art

[0002] When using certain electrical equipment, there are situations where the control circuit only needs to be turned on briefly, but not for a long time. For example, for a car horn, if the driver holds down the horn button for a long time without letting go, and the horn's control circuit is always connected, and the horn honks continuously for a long time, it may cause unnecessary conflicts. For another example, for industrial equipment such as stamping machines or laminating machines, if the operator holds down the switch button for a long time so that the control circuit of the equipment is always in the on state, it is likely to bring safety hazards and cause production accidents and personal injuries.

DETAILED DESCRIPTION

[0053] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0054] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0055] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0056] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0057] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0058] Reference Figures 1 to 8 As shown, according to an embodiment of the present application, a switch mechanism 1 is provided. The switch mechanism 1 comprises a connecting member 10, a first electrode 11 and a second electrode 12, wherein the first electrode 11 is rotatably mounted on the connecting member 10, and the first electrode 11 can rotate relative to the connecting member 10; the second electrode 12 is fixedly mounted on the connecting member 10, and the second electrode 12 is arranged on one side of the first electrode 11, and at least a part of the structure of the second electrode 12 is located on the rotation track of the first electrode 11;

[0059] It also includes a first driving member 13, which is slidably disposed on the connecting member 10, and the first driving member 13 can move translationally relative to the connecting member 10;

[0060] The first driving member 13 moves translationally under the action of an external force to drive the first electrode 11 to rotate;

[0061] The circuit corresponding to the switch mechanism has an off state and an on state, and the circuit is switched from the off state to the on state only when the first electrode 11 rotates and touches the second electrode 12 .

[0062] In the switch mechanism 1 provided in the embodiment of the present application, the first driving member 13 as the control member (e.g., control button) of the switch mechanism 1 receives the external force (e.g., manual force applied by the user), and the motion trajectory of the first driving member 13 under the external force is a linear translation motion; while the motion trajectory of the first electrode 11 is a rotation. Therefore, when the first driving member 13 drives the first electrode 11 under the external force, the first driving member 13 cannot continuously drive the first electrode 11 to rotate. After the first driving member 13 drives the first electrode 11 to rotate, even if the first driving member 13 continues to perform a linear translation motion, since the motion trajectory of the first electrode 11 is rotation, the first electrode 11 will not follow the motion trajectory of the first driving member 13, and therefore the first electrode 11 will only continue to rotate under the action of inertia until it stops.

[0063] Furthermore, since the second electrode 12 is located on one side of the first electrode 11, during the entire circular rotation of the first electrode 11, the circuit corresponding to the switch mechanism 1 can be turned on only when the first electrode 11 rotates to the position of the second electrode 12 and touches the second electrode 12; and when the first electrode 11 rotates to other positions without touching the second electrode 12, the circuit corresponding to the switch mechanism 1 is in a disconnected state.

[0064] To sum up, when using the switch mechanism 1 provided in the embodiment of the present application, in the process of applying a force to the first driving member 13 to drive the first electrode 11 to rotate, the first electrode 11 will only briefly contact the second electrode 12 to make the circuit corresponding to the switch mechanism 1 conductive, and the circuit corresponding to the switch mechanism 1 will not be continuously conductive, thereby meeting the special usage requirements of some electrical equipment and improving the safety of use.

[0065] Reference Figure 2 to Figure 5 As shown, in one embodiment, the switch mechanism also includes a second driving member 14, the second driving member 14 is rotatably mounted on the connecting member 10, and the second driving member 14 is fixedly connected to the first electrode 11, and the second driving member 14 rotates synchronously with the first electrode 11; the second driving member 14 is correspondingly arranged to the first driving member 13, the first driving member 13 translates under the action of an external force to drive the second driving member 14 to rotate, and the second driving member 14 drives the first electrode 11 to rotate synchronously.

[0066] In this specific example, through the relaying effect of the second driving member 14, the second driving member 14 receives the driving force of the first driving member 13 on the one hand, and drives the first electrode 11 to rotate synchronously on the other hand, so that the first driving member 13 does not need to act directly on the first electrode 11, thereby avoiding the first driving member 13 frequently touching the first electrode 11 and causing damage to the first electrode 11.

[0067] In addition, the motion trajectory of the first driving member 13 under the action of an external force is a linear translation motion, while the motion trajectory of the second driving member 14 that receives the driving force of the first driving member 13 and drives the first electrode 11 to move is a rotation. Therefore, when the first driving member 13 drives the second driving member 14 under the action of an external force, the first driving member 13 cannot continuously drive the second driving member 14 to rotate. After the first driving member 13 drives the second driving member 14 to rotate, even if the first driving member 13 continues to perform a linear translation motion, since the motion trajectory of the second driving member 14 is a rotation, the second driving member 14 will not follow the motion trajectory of the first driving member 13, and therefore the second driving member 14 will only continue to rotate under the action of inertia until it stops.

[0068] Reference Figure 1 to Figure 4As shown, in one embodiment, the connecting member 10 includes a mounting plate 101, a guide block 102 and a column 103, the guide block 102 and the column 103 are both mounted on the mounting plate 101, and the guide block 102 and the column 103 are arranged opposite to each other;

[0069] The first electrode 11 and the second driving member 14 are rotatably mounted on the column 103 , the second electrode 12 is fixedly mounted on the mounting plate 101 , and the first driving member 13 is slidably disposed on the guide block 102 .

[0070] In this specific example, the mounting plate 101 provides installation and support for the guide block 102, the column 103 and the second electrode 12. The guide block 102 provides a guide for the linear translation sliding of the first driving member 13; specifically, a slide groove 1020 is provided on the guide block 102, and the first driving member 13 slides along the slide groove 1020. The column 103 is used to install the first electrode 11 and the second driving member 14.

[0071] In addition, the switch mechanism also includes a shell 17 and a terminal 18, the first electrode 11 and the second electrode 12 are arranged inside the shell 17, and the terminal 18 is arranged outside the shell 17; the terminal 18 includes a first terminal 181 and a second terminal 182, the first terminal 181 is electrically connected to the first electrode 11; the second terminal 182 is electrically connected to the second electrode 12.

[0072] The housing 17 has a housing bottom and an opening that are arranged opposite to each other. The housing 17 is connected to the mounting plate 101 at its opening. The housing 17 and the mounting plate 101 enclose a housing cavity. The first electrode 11, the second electrode 12 and the second driving member 14 are all completely arranged in the housing cavity. In order to facilitate the external connection of the switch mechanism 1 to the circuit loop, a first wiring terminal 181 and a second wiring terminal 182 are arranged outside the housing cavity. The first wiring terminal 181 is electrically connected to the first electrode 11, and the second wiring terminal 182 is electrically connected to the second electrode 12. For example, the first wiring terminal 181 and the second wiring terminal 182 can be arranged on the side of the mounting plate 101.

[0073] The housing 17 is provided with a window portion 170 at the bottom thereof, and one end of the first driving member 13 extends out of the accommodating cavity through the window portion 170 to receive an external force.

[0074] Refer to the figure Figure 2 to Figure 4 As shown, in one embodiment, the first driving member 13 includes a pressing block 131 and a push rod 132, the first end of the pressing block 131 is used to receive an external force, and the second end of the pressing block 131 is slidably connected to the guide block 102;

[0075] The first end of the push rod 132 is fixedly connected to the pressing block 131 , and the second end of the push rod 132 is in a free state and is disposed corresponding to the second driving member 14 .

[0076] In this specific example, the pressing block 131 slides along the slide groove 1020 of the guide block 102 under the action of external force and drives the push rod 132 to perform linear translational motion; the push rod 132 is a cantilever structure with a fixed first end and a suspended second end. When the push rod 132 performs linear translational motion and its second end touches the second driving member 14, the push rod 132 drives the second driving member 14 to rotate.

[0077] Furthermore, the pressing block 131 includes a button portion 1311 and a lug 1312; the button portion 1311, the push rod 132 and the slide groove 1020 all extend in the same direction, as shown in FIG. Figure 4 The direction a shown in the figure is the direction in which the first driving member 13 performs linear translational motion. The extension direction of the lug 1312 forms a certain angle with the direction a, for example, perpendicular to the direction a; the first end of the push rod 132 is fixedly connected to the lug 1312. Optionally, the lug 1312 and the button portion 1311 can be an integrated structure; or the lug 1312 and the button portion 1311 can be a split structure and the two are fixedly connected together.

[0078] Optionally, a limit block 100 can be set on the guide block 102 to limit the linear translation movement of the lug 1312 to prevent the button part 1311 from being pressed down excessively, but it should be noted that the setting position of the limit block 100 needs to ensure that the first electrode 11 can be activated when the button part 1311 is pressed.

[0079] Reference Figure 2 As shown, in one embodiment, the first driving member 13 further includes a spring 133 , the spring 133 is mounted on the guide block 102 , and the second end of the pressing block 131 is fixedly connected to the spring 133 .

[0080] In this specific example, when the external force applied to the first driving member 13 is removed, the spring 133 is used to provide an elastic restoring force to the pressing block 131 so that the pressing block 131 returns to its initial position to prepare for the next use.

[0081] Reference Figure 7 As shown, in one embodiment, the second driving member 14 includes a first bearing 141, a first blade 142 and a second blade 143, the first blade 142 and the second blade 143 are both connected to the first bearing 141, and the first blade 142 and the second blade 143 are symmetrically arranged relative to the first bearing 141; the first bearing 141 is rotatably mounted on the connecting member 10.

[0082] In this specific example, the second driving member 14 is a rotating blade structure; it includes a first bearing 141 for rotationally connecting to the connecting member 10 , and a first blade 142 and a second blade 143 symmetrically arranged on both sides of the first bearing 141 .

[0083] Optionally, the second driving member 14 may include only one blade, or include more than three blades. The second driving member 14 includes two symmetrically arranged blades, which can make its overall structure balanced and simple.

[0084] Reference Figure 7 As shown, in one embodiment, the first blade 142 includes a first front side 1421 and a first back side 1422 that are arranged opposite to each other, and the first front side 1421 is provided with a first groove 1420;

[0085] The second blade 143 includes a second front side 1431 and a second back side 1432 which are arranged opposite to each other. The second front side 1431 defines a second groove 1430 .

[0086] In this specific example, the first groove 1420 formed on the first front side 1421 can make the first blade 142 more easily deformed; and the second groove 1430 formed on the second front side 1431 can make the second blade 143 more easily deformed.

[0087] Furthermore, a plurality of first grooves 1420 may be arranged at intervals, and the first grooves 1420 pass through the first front side 1421 and the two side surfaces of the first blade 142; due to the first groove 1420, the structure between the first back side 1422 and the bottom of the first groove 1420 is thinned to form a first thin sheet structure. The material of the first blade 142 may be elastic plastic, leather or metal, and the material of the first thin sheet structure may also be elastic plastic, leather or metal. The elastic strength of the first thin sheet structure is that when the first blade 142 is not pushed by an external force, it can support the first blade 142 to achieve a horizontal and vertical state; and when pushed by an external force, it can deform and bend accordingly. For example, when the first front side 1421 is subjected to a thrust, the first blade 142 will bend toward the first back side 1422 relatively easily due to the characteristics of the first thin sheet structure, and can be restored when the thrust ends. When the first back side 1422 is subjected to thrust, the first blade 142 will bend toward the first front side 1421 to a limited extent. This is because the side walls on both sides of the first groove 1420 will be squeezed together to form resistance, thus preventing the first blade 142 from continuing to deform toward the first front side 1421. The first blade 142 is basically still in a horizontal and vertical shape.

[0088] Similarly, multiple second grooves 1430 can be arranged at intervals, and the second grooves 1430 pass through the second front side 1431 and the two side surfaces of the second blade 143; due to the second groove 1430, the structure between the second back side 1432 and the bottom of the second groove 1430 is thinned to form a second thin sheet structure. The material of the second blade 143 can be elastic plastic, leather or metal, and the material of the second thin sheet structure is also elastic plastic, leather or metal. The elastic strength of the second thin sheet structure is that when the second blade 143 is not pushed by an external force, it can support the second blade 143 to achieve a horizontal and vertical state; and when it is pushed by an external force, it can deform and bend accordingly. For example, when the second front side 1431 is subjected to a thrust, the second blade 143 will bend toward the second back side 1432 more easily due to the characteristics of the second thin sheet structure, and it can be restored when the thrust ends. When the second back side 1432 is subjected to thrust, the second blade 143 will bend toward the second front side 1431 to a limited extent. This is because the side walls on both sides of the second groove 1430 will be squeezed together to form resistance, thus preventing the second blade 143 from continuing to deform toward the second front side 1431. The second blade 143 is basically still in a horizontal and vertical shape.

[0089] Reference Figure 4 As shown, in one embodiment, the switch mechanism has an initial state, and when the switch mechanism is in the initial state, the circuit corresponding to the switch mechanism is in an open state;

[0090] When the switch mechanism is in an initial state, the first back side 1422 or the second back side 1432 is arranged corresponding to the first driving member 13; and the center lines of the first blade 142 and the second blade 143 are inclined relative to the direction of translational movement of the first driving member 13.

[0091] In this specific example, when the switch mechanism is in the initial state, the first back surface 1422 or the second back surface 1432 is arranged corresponding to the second end of the push rod 132 in the first driving member 13, and when the first driving member 13 drives the second driving member 14, the push rod 132 pushes the first back surface 1422 or the second back surface 1432. Since the first back surface 1422 and the second back surface 1432 are smooth surfaces without grooves, the push rod 132 will not be stuck when pushing the first back surface 1422 or the second back surface 1432.

[0092] Optionally, the second end of the push rod 132 may be configured as a rounded structure to facilitate smoother movement when the second end of the push rod 132 pushes the first back side 1422 or the second back side 1432 .

[0093] Furthermore, when the switch mechanism is in the initial state, the center lines of the first blade 142 and the second blade 143 are tilted relative to the direction of translation of the first driving member 13; in other words, the center lines of the first blade 142 and the second blade 143 are tilted relative to the extension direction of the push rod 132; thereby ensuring that when the push rod 132 contacts the first blade 142 or the second blade 143, it can push the second driving member 14 to perform rotational movement. If the center lines of the first blade 142 and the second blade 143 are in the same extension direction as the push rod 132, it is possible that the push rod 132 cannot push the second driving member 14.

[0094] The structural features and arrangement of the first blade 142 and the second blade 143 are conducive to the second driving member 14 driving the first electrode 11 to rotate and reset. In the process of the second driving member 14 driving the first electrode 11 to rotate and reset, if the first front side 1421 hits the push rod 132, the first blade 142 will fall in the direction of the first back side 1422; if the second front side 1431 hits the push rod 132, the second blade 143 will fall in the direction of the second back side 1432; thus, the second driving member 14 driving the first electrode 11 to rotate and reset will not be affected.

[0095] Reference Figure 6 As shown, in one embodiment, the first electrode 11 includes a main body 111 and a second bearing 112, the main body 111 is provided with a center hole 110, the second bearing 112 is connected to the main body 111, and the second bearing 112 is arranged at the center hole 110, the second bearing 112 is rotatably installed on the connecting member 10, and the second bearing 112 is fixedly connected to the first bearing 141.

[0096] In this specific example, the first electrode 11 is rotatably connected to the column 103 in the connecting member 10 through a second bearing 112 arranged at the central hole 110 of its main body 111; and the second bearing 112 is fixedly connected to the first bearing 141 of the second driving member 14, so that the first electrode 11 can rotate synchronously with the second driving member 14.

[0097] Reference Figure 5 As shown, further, the column 103 includes a column 1031 and a shaft 1032, one end of the column 1031 is fixedly mounted on the mounting plate 101, the first end of the shaft 1032 is fixedly connected to the column 1031 and is arranged close to the other end of the column 1031, and the second end of the shaft 1032 is in a free state.

[0098] The first plane bearing 191 , the second bearing 112 of the first electrode 11 , the first bearing 141 of the second driving member 14 , the second plane bearing 192 and the cap 193 are sequentially sleeved on the shaft 1032 via the second end of the shaft 1032 .

[0099] Among them, the first plane bearing 191 is used to reduce the friction resistance between the first electrode 11 and the cylinder 1031; the second bearing 112 is a linear bearing, which can reduce the friction resistance between the first electrode 11 and the shaft 1032; the first bearing 141 is a linear bearing, which can reduce the friction resistance between the second driving member 14 and the shaft 1032; the second plane bearing 192 is used to reduce the friction resistance between the second driving member 14 and the cap 193; the cap 193 can prevent the second driving member 14, the first electrode 11 and other components installed on the shaft 1032 from falling off.

[0100] Reference Figure 3 As shown, in one embodiment, the switch mechanism further includes a first stopper 15 and a second stopper 16, and the first stopper 15 and the second stopper 16 are installed on the connecting member 10;

[0101] The switch mechanism has an initial state, and when the switch mechanism is in the initial state, the circuit corresponding to the switch mechanism is in an open state; when the switch mechanism is in the initial state, the first electrode 11 is located between the first stopper 15 and the second stopper 16 .

[0102] In this specific example, the first stopper 15 and the second stopper 16 are both fixedly mounted on the column 1031. When the switch mechanism is in the initial state, the first electrode 11 is located between the first stopper 15 and the second stopper 16; after the first electrode 11 follows the second driving member 14 to freely rotate and reset under the action of inertia, the first electrode 11 returns to the position between the first stopper 15 and the second stopper 16, and the first stopper 15 and the second stopper 16 block the free rotation of the first electrode 11 under the action of inertia, thereby facilitating the rapid reset of the first electrode 11.

[0103] Among them, refer to Figure 8 As shown, the first stopper 15 is a flexible stopper; the second stopper 16 has a first side surface 161, a second side surface 162, a third side surface 163 and a fourth side surface 164; wherein the first side surface 161 is arranged opposite to the first stopper 15, the second side surface 162 is arranged opposite to the first side surface 161, the third side surface 163 is arranged opposite to the fourth side surface 164, and the third side surface 163 is connected between the first side surface 161 and the second side surface 162, and the fourth side surface 164 is connected between the first side surface 161 and the second side surface 162;

[0104] The second stopper 16 defines a third groove 160 passing through the second side surface 162 , the third side surface 163 , and the fourth side surface 164 .

[0105] In this specific example, the first stopper 15 can be a metal sheet or a plastic sheet; in order to avoid unnecessary electrical conduction and short circuit, it is better to use a plastic sheet for the first stopper 15; the first stopper 15 is configured to be able to block the inertial impact strength of the first electrode 11 when it rotates freely, but cannot block the strength when the button part 1311 is pressed down to drive the push rod 132 to push the second driving member 14 and then drive the first electrode 11 to rotate.

[0106] The structural design of the second stopper 16 is similar to the first blade 142 and the second blade 143; a reset space for the first electrode 11 is formed between the first stopper 15 and the second stopper 16, and a third groove 160 is provided on the outer side surface (second side surface 162) of the second stopper 16 away from the reset space. The setting of the third groove 160 is conducive to the deformation and bending of the second stopper 16 from the outer side to the inner side surface (from the second side surface 162 to the first side surface 161); therefore, when the first electrode 11 rotates freely under the action of inertia and passes through the second side surface 162, the second side surface 162 can easily bend and deform in the direction of the first side surface 161, and the first electrode 11 can easily pass through. After the first electrode 11 passes through, the second stopper 16 rebounds and resets due to its own toughness. After passing through the second stopper 16, the first electrode 11 enters the reset space formed between the first stopper 15 and the second stopper 16, and is blocked by the first stopper 15 and cannot continue to rotate, thereby stopping in the reset space. At this time, the first electrode 11 is in a 90° vertical state (i.e., along the Figure 4 The second driving member 14 is in a state of being displaced at a certain angle with the first electrode 11, and the first back side 1422 or the second back side 1432 of the second driving member 14 is arranged corresponding to the second end of the push rod 132. At this time, the components of the switch mechanism 1 are in a reset state, waiting for the next operation.

[0107] Reference Figure 1 As shown, in one embodiment, the weight of the second driving member 14 is no more than 1 / 3 of the weight of the first electrode 11 .

[0108] In this specific example, the first electrode 11 is centered on its central hole 110, and the weight on both sides is equal; the second driving member 14 is centered on the first bearing 141, and the weight on both sides is equal; in order not to affect the resetting of the first electrode 11, the weight of the second driving member 14 cannot be greater than one third of the weight of the first electrode 11.

[0109] Reference Figure 3 , Figure 6As shown, in one embodiment, the first electrode 11 has a first abutting end 1111 and a second abutting end 1112 that are arranged opposite to each other, and the first abutting end 1111 and the second abutting end 1112 are used to touch the second electrode 12;

[0110] The second electrode 12 has a fixed end 1201 and a free end 1202 , wherein the fixed end 1201 is fixedly mounted on the connector 10 , and the free end 1202 is used to touch the first electrode 11 ;

[0111] The first abutting end 1111 , the second abutting end 1112 , and the free end 1202 are all rounded structures.

[0112] In this specific example, the first abutting end 1111, the second abutting end 1112 and the free end 1202 are configured as rounded structures to reduce resistance when the first electrode 11 and the second electrode 12 touch each other, thereby ensuring that the first electrode 11 can pass more smoothly.

[0113] Reference Figure 3 As shown, in one embodiment, the second electrode 12 includes a first pole piece 121 and a second pole piece 122, one end of the first pole piece 121 is fixedly mounted on the connecting member 10, one end of the first pole piece 121 is the fixed end 1201, the other end of the first pole piece 121 is connected to one end of the second pole piece 122, and the other end of the second pole piece 122 is the free end 1202.

[0114] In this specific example, the second electrode 12 is approximately in the shape of a letter "7", wherein the first electrode piece 121 is fixedly supported on the mounting plate 101, and the second electrode piece 122 is in a cantilever state to facilitate the first electrode 11 to rotate and contact the second electrode 12 and then leave.

[0115] Of course, the second electrode 12 may also include only one electrode sheet, and the electrode sheet may be installed on the mounting plate 101 in an inclined manner.
