An electric switch contains a moving contact and a stationary contact, which are controlled by closing or separating the moving and stationary contacts to control the on / off state of the circuit.

[0003] In the prior art, an electric switch generally includes a plurality of current input terminals, which increases the burden of the installation space inside the electric switch and increases the use and production costs. Utility Model Content

The first limiting structure includes a first limiting member and a second limiting member, and the first limiting member and the second limiting member are respectively arranged on both sides of the connecting member.

[0015] Based on the description of the above embodiment, by respectively setting a first limit member and a second limit member on both sides of the connecting member, the displacement of the connecting member moving to both sides is limited, thereby controlling the swing amplitude of the connecting member to be within a certain range, avoiding occupying more installation space in the electric switch, and further reducing production costs.

[0016] In one possible design, the electric switch may further include a second limiting structure. The second limiting structure is disposed on the motion trajectory of the moving contact bridge.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0039] The terms "comprises", "comprising" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover but not exclude other contents. The word "a" or "an" does not exclude the presence of a plurality.

[0040] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiment" in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0042] The directional words appearing in the following description are all directions shown in the drawings and do not limit the specific structure of this application. For example, in the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting this application.

[0043] In addition, the expressions indicating directions such as the X direction, Y direction, and Z direction used to illustrate the operation and construction of the various components of this embodiment are not absolute but relative, and although these indications are appropriate when the various components are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

[0044] In addition, the terms "first", "second", etc. in the description and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order, and may explicitly or implicitly include one or more such features.

[0045] In the description of this application, unless otherwise specified, "plurality" means more than two (including two), and similarly, "multiple groups" means more than two (including two).

For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate element, as long as the circuit is interconnected. It can also refer to internal communication between two elements. A signal connection can refer to a signal connection through a circuit or a signal connection through a media medium, such as radio waves. Those skilled in the art will understand the specific meanings of the above terms in this application.

[0047] like Figure 1 and Figure 2 As shown, the first aspect of the present application provides an electric switch 100, which includes: a drive mechanism 2, a transmission structure 1, a moving contact assembly 3, a first static contact 4, a second static contact 5 and a third static contact 6. The drive mechanism 2 is connected to the transmission structure 1, and is used to drive the transmission structure 1 to operate. The transmission structure 1 is connected to the moving contact assembly 3, and is used to drive the moving contact assembly 3 to operate. The moving contact assembly 3 includes a first end 3a and a second end 3b. The first static contact 4 and the second static contact 5 are respectively arranged on both sides of the first end 3a. The third static contact 6 is connected to the second end 3b. When the moving contact assembly 3 operates, the first end 3a performs a reciprocating motion and is connected to the first static contact 4 or the second static contact 5. The first static contact 4 is connected to the first output line. The second static contact 5 is connected to the second output line. The third static contact 6 is connected to the first input line.

[0048] The drive mechanism 2 is the component within the electric switch 100 that provides power and motion. It converts electrical energy, fuel energy, and other energy into mechanical energy to drive the other components within the electric switch 100. For example, the drive mechanism 2 is connected to the transmission structure 1 so that the drive mechanism 2 drives the transmission structure 1 to rotate.

[0049] The transmission structure 1 is used to convert the motion output by the drive structure into reciprocating motion. The motion output by the drive mechanism 2 can be rotational motion, and the reciprocating motion can be oscillating motion. Specifically, the transmission structure 1 can be a crank or a gear set.

[0050] The movable contact assembly 3 includes a first end 3a and a second end 3b. The first end 3a reciprocates with the transmission structure 1. The reciprocating motion may include a first direction X and a direction opposite to the first direction X. Since the first and second stationary contacts 4 and 5 are disposed on either side of the movable first end 3a, the first direction X may be the direction of movement from the first end 3a toward the first stationary contact 4, and the direction opposite to the first direction X may be the direction of movement from the first end 3a toward the second stationary contact 5.

[0051] Therefore, when the first end 3 a performs reciprocating motion, it can be connected to the first stationary contact 4 or the second stationary contact 5 .

[0052] The first static contact 4 is connected to the first output line, so that the electric switch 100 is connected to the external circuit through the first output line.

[0053] The second static contact 5 is connected to the second output line, so that the electric switch 100 is connected to the external circuit through the second output line.

[0054] When the first end 3a is connected to the first static contact 4, the first output circuit is connected. Conversely, when the first end 3a is not connected to the first static contact 4, the first output circuit is disconnected.

[0055] Similarly, when the first end 3a is connected to the second static contact 5, the second output circuit is connected. Conversely, when the first end 3a is not connected to the second static contact 5, the second output circuit is disconnected.

[0056] Specifically, the output circuit outputs current to the external circuit through the electric switch 100. The two output circuits can be connected to two electrical devices respectively, so that the electric switch 100 can control the two electrical devices respectively, thereby reducing the number of switches and lowering production costs.

[0057] Furthermore, the third static contact 6 is connected to the first input line, so that the electric switch 100 is connected to the external circuit through the first input line.

[0058] Specifically, the first input line is an external line that inputs current to the electric switch 100. Therefore, the second end 3b is connected to the third static contact 6 so that the electric switch 100 can input current to the electric switch 100 through only one input line.

[0059] In related art, the electric switch 100 may include a first input line and a second input line. The first input line is connected to the first output line, and the second input line is connected to the second output line. Based on this, the present application only uses a single input line to input current to the electric switch 100, simplifying the structure of the electric switch 100 and further reducing production costs.

[0060] In summary, the drive mechanism 2 is connected to the transmission structure 1, which is in turn connected to the movable contact assembly 3, enabling the drive mechanism 2 to drive the movable contact assembly 3. The reciprocating motion of the first end 3a of the movable contact assembly 3 controls the connection or disconnection of the first or second output circuits in the electric switch 100, thereby reducing the number of switches and lowering production costs. Furthermore, the connection of the second end 3b to the third static contact 6 allows the electric switch 100 to input current solely through the first input circuit, simplifying the structure of the electric switch 100 and further reducing production costs.

[0061] Specifically, the connection modes between the second end 3b and the third static contact 6 may include but are not limited to the following two:

[0062] Connection mode 1: the second end 3 b is slidably connected to the third static contact 6 .

[0063] Specifically, a sliding groove or a sliding block can be provided on the third static contact 6. Correspondingly, a sliding block or a sliding groove can be provided on the second end 3b. The sliding block slides within the sliding groove without affecting the movement of the first end 3a. The sliding block and the sliding groove can remain connected to each other, thereby maintaining connectivity of the first input line.

[0064] Connection method 2, such as Figure 2 As shown, the second end 3b is rotatably connected to the third static contact 6.

[0065] Specifically, the second end 3b can be rotatably connected to the third static contact 6 through a positioning pin, and the second end 3b rotates on the third static contact 6 with the positioning pin as the rotation center, while not affecting the action of the first end 3a, so that the second end 3b and the positioning pin are always in a connected state, so that the first input line remains connected.

[0066] In summary, operators can choose the above two connection methods according to specific circumstances.

[0067] Furthermore, if Figure 3 As shown, in some embodiments, the moving contact assembly 3 may include a connecting member 31 and a moving contact bridge 32. The connecting member 31 is connected to the transmission structure 1 and moves together with the transmission structure 1. The moving contact bridge 32 is fixed to the connecting member 31 and moves together with the connecting member 31.

[0068] Specifically, the connecting member 31 can be a hollow circular rotating shaft. The circular rotating shaft is disposed between the first end 3a and the second end 3b. The movable contact bridge 32 is sleeved within the rotating shaft. When the rotating shaft and the transmission structure 1 operate together, the inner wall of the hollow rotating shaft drives the movable contact bridge 32 to operate. The movable contact bridge 32 is an electrical connecting member 31. One end of the movable contact bridge 32 is connected to the first static contact 4 or the second static contact 5, and the other end of the movable contact bridge 32 is connected to the third static contact 6, thereby enabling current flow in the electric switch 100.

[0069] According to the description of the above embodiment, a connector 31 is provided between the moving contact bridge 32 and the transmission structure 1 so that the transmission structure 1 can drive the moving contact bridge 32 to rotate together, ensuring that the current in the electric switch 100 can flow normally.

[0070] Further, if Figure 3 and Figure 4 As shown, in some embodiments, the connecting member 31 is provided with a first clamping structure 311, and the transmission structure 1 is provided with a second clamping structure 11. The first clamping structure 311 is clamped and connected with the second clamping structure 11, so that the connecting member 31 and the transmission structure 1 rotate together.

[0071] The first engaging structure 311 can be a engaging groove or an engaging block. Similarly, the second engaging structure 11 can be a engaging groove or an engaging block. The engaging block is engaged in the engaging groove, so that the connecting member 31 rotates together with the transmission structure 1.

[0072] The first engaging structure 311 is a engaging slot, and the second engaging structure 11 is a engaging block. Alternatively, the first engaging structure 311 is a engaging block, and the second engaging structure 11 is a engaging slot. The engaging surfaces of the engaging slot and the engaging block have the same shape. For example, the engaging surface can be rectangular, star-shaped, or the like.

[0073] According to the description of the above embodiment, the connecting member 31 is provided with a first engaging structure 311 within the electric switch 100 and on the connecting member 31, and the transmission structure 1 is provided with a second engaging structure 11. The first engaging structure 311 is engaged with the second engaging structure 11, so that the connecting member 31 rotates together with the transmission structure 1, thereby enabling the drive mechanism 2 to control the movement of the moving contact bridge 32.

[0074] Furthermore, when the movement of the connecting member 31 is too large, it will occupy more installation space in the electric switch 100. In order to save the installation space in the electric switch 100, the present application has made the following design. Figure 5 Provide a detailed description.

[0075] The electric switch 100 provided in the embodiment of the present application may further include a first limiting structure. The first limiting structure is disposed on the motion trajectory of the connecting member 31. The first limiting structure includes a first limiting member 312 and a second limiting member 313, which are respectively disposed on either side of the connecting member 31.

[0076] When the connecting member 31 moves toward the first limiting member 312 and reaches the position where the first limiting member 312 is set, the first limiting member 312 abuts against the connecting member 31, restricting the connecting member 31 from continuing to move in that direction. Similarly, when the connecting member 31 moves toward the second limiting member 313 and reaches the position where the second limiting member 313 is set, the second limiting member 313 abuts against the connecting member 31, restricting the connecting member 31 from continuing to move in that direction.

[0077] In order to further save material and production costs, the first limiter 312 and the second limiter 313 can be components that already exist in the electric switch 100. Figure 5 As shown, the first stopper 312 and the second stopper 313 may be mounting slots in the electric switch 100. The mounting slots are provided on the housing of the electric switch 100 and are used to mount the connector 31. By configuring the sidewalls of the mounting slots in the direction of movement of the connector 31 as the first stopper 312 and the second stopper 313, the mounting slots not only serve as mounting and positioning functions but also serve to limit the connector 31, further reducing production costs.

[0078] According to the description of the above embodiment, by respectively providing a first limit member 312 and a second limit member 313 on both sides of the connecting member 31, the displacement of the connecting member 31 moving to both sides is limited, thereby controlling the swing amplitude of the connecting member 31 to be within a certain range, avoiding occupying more installation space in the electric switch 100, and further reducing the production cost.

[0079] Similarly, when the amplitude of the movement of the movable contact bridge 32 in the electric switch 100 is too large, it will occupy more installation space in the electric switch 100. In order to save the installation space in the electric switch 100, the present application has made the following design. Figure 6-Figure 7 Provide a detailed description.

[0080] The electric switch 100 provided in this embodiment of the present application may further include a second limiting structure. The second limiting structure is disposed on the motion trajectory of the moving contact bridge 32. The second limiting structure includes a third limiting member 321 and a fourth limiting member 322, which are respectively disposed on either side of the moving contact bridge 32.

[0081] When the movable contact bridge 32 moves toward the third limiter 321 and reaches the position where the third limiter 321 is set, the third limiter 321 abuts against the movable contact bridge 32, restricting further movement of the movable contact bridge 32 in that direction. Similarly, when the movable contact bridge 32 moves toward the second limiter 313 and reaches the position of the fourth limiter 322, the fourth limiter 322 abuts against the movable contact bridge 32, restricting further movement of the movable contact bridge 32 in that direction.

[0082] In order to further save materials and production costs, the third limiting member 321 and the fourth limiting member 322 can be components that already exist in the electric switch 100. For example, Figure 7 As shown, the third limiting member 321 and the fourth limiting member 322 can be positioning pins in the electric switch 100. Two of the positioning pins are arranged on the motion trajectory of the movable contact bridge 32, so that the positioning pins can not only fix the movable contact bridge 32 but also limit the movable contact bridge 32, thereby further reducing production costs.

[0083] According to the description of the above embodiment, by respectively providing a third limit member 321 and a fourth limit member 322 on both sides of the moving contact bridge 32, the displacement of the moving contact bridge 32 moving to both sides is limited, thereby controlling the swing amplitude of the moving contact bridge 32 within a certain range, avoiding occupying more installation space in the electric switch 100, and further reducing the production cost.

[0084] Furthermore, the electric switch 100 has many internal components and the assembly process is complicated. Therefore, the electric switch 100 is prone to assembly errors during the assembly process, resulting in the misalignment of some components, which in turn affects the reliability of the electric switch 100. In order to solve the above problems, the present application has made the following designs:

[0085] In some embodiments, the electric switch 100 may further include a first mounting groove 41 and a second mounting groove 51. The first mounting groove 41 is used to mount and fix the first static contact 4. The second mounting groove 51 is used to mount and fix the second static contact 5.

[0086] like Figure 5 As shown, the first mounting groove 41 can guide the first static contact 4 during installation, reducing the difficulty of installing the first static contact 4. The first mounting groove 41 can also limit the first static contact 4 during installation, thereby reducing the probability of the first static contact 4 being misaligned or falling when the electric switch 100 is bumped or shaken, thereby improving the reliability of the electric switch 100.

[0087] Similarly, if Figure 5As shown, the second mounting groove 51 can guide the second static contact 5 during installation, reducing the difficulty of installing the second static contact 5. The second mounting groove 51 can also limit the second static contact 5 during installation, thereby reducing the probability of the second static contact 5 being misaligned or falling when the electric switch 100 is bumped or shaken, thereby improving the reliability of the electric switch 100.

[0088] In summary, the first mounting groove 41 and the second mounting groove 51 are designed in the electric switch 100. The first mounting groove 41 is used to install and fix the first static contact 4, and the second mounting groove 51 is used to install and fix the second static contact 5, thereby improving the reliability of the electric switch 100.

[0089] In some embodiments, as Figure 2 As shown, the drive mechanism 2 includes a motor 21, a reduction assembly (not shown), and an output shaft 22. The motor 21 is used to provide an initial rotational speed. The reduction assembly includes an input shaft and an output shaft 22. The input shaft is connected to the motor 21, and the output shaft 22 is connected to the transmission structure 1.

[0090] The motor 21 is a device that converts electrical energy into mechanical energy. The motor 21 generates torque and rotational motion through the interaction of currents in a magnetic field.

[0091] The reduction assembly is used to reduce the output speed of motor 21. The reduction assembly may include an input shaft and an output shaft 22. The input shaft is connected to motor 21 and is used to transmit the initial speed of motor 21 to the reduction assembly. The output shaft 22 is connected to transmission structure 1 and is used to transmit the final speed to transmission structure 1. The final speed is lower than the initial speed.

[0092] Specifically, the reduction assembly generally reduces speed by one or more meshing gear sets. When the high-speed rotation of the motor 21 passes through the reduction assembly, the initial speed of the motor 21 output is reduced by adjusting the gear ratios of the gears in the gear set.

[0093] According to the description of the above embodiments, by providing a reduction assembly between the transmission structure 1 and the motor 21, the initial rotational speed of the motor 21 is reduced, thereby reducing the movement speed of the transmission structure 1, thereby increasing the service life of the transmission structure 1. Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of this application and form different embodiments. For example, in the claims, any of the claimed embodiments may be used in any combination.

[0094] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
