Description

Technical Field

[0001] This application belongs to the field of electrical control technology, specifically relating to a multi-position control switch. Background Technology

[0002] In electrical control systems, multi-position control switches serve as core components for adjusting equipment functions and optimizing parameters. Through preset different positions, they can precisely control the on / off state of circuits, current magnitude, and equipment operating modes, playing an indispensable role in industrial production, smart homes, and kitchen appliances. They can flexibly adjust the equipment's output power or operating status according to actual needs, significantly improving the convenience and applicability of equipment use and providing users with diverse operational options.

[0003] Taking kitchen appliance mixers as an example, multi-speed control switches are widely used to adjust the mixing speed and whipping intensity. Users can switch between different speed levels by rotating the switch to suit the needs of whipping different ingredients such as eggs and cream. However, existing multi-speed control switches for mixers have certain limitations: when users need to enhance the whipping function and switch to a higher control level, the mixer gains greater rotational energy, but this can easily lead to over-whipping of the ingredients, affecting the quality of the finished product; conversely, if a lower rotational energy level is selected, insufficient whipping energy will result in a significantly longer whipping time, or even problems such as under-whipping and uneven texture. Because existing multi-speed control switches only provide fixed speed adjustments and lack the ability to dynamically adjust whipping parameters based on the characteristics of the ingredients and environmental factors, they cannot meet users' needs for efficient and precise whipping, thus limiting further improvements in mixer performance.

[0022] The second control component is fixedly connected to the second conductive piece, and the conductive shaft passes through the second control component to control the second conductive piece to connect or disconnect with the corresponding gear guide piece.

[0023] In some implementations, the second control element is provided with a positioning post and a limiting block, the positioning post passing through the second conductive piece, and the limiting block being provided on both sides of the second conductive piece.

[0024] In some implementations, the second control element is provided with a protrusion, the upper end of which abuts against the second conductive piece to raise the second conductive piece for rotation.

[0025] In some implementations, the conductive shaft is a hollow conductive shaft.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0047] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0048] Example 1:

[0049] Please see the appendix Figure 1-4 The multi-position control switch of this application includes a conductive component 1 and a control mechanism 2.

[0050] The conductive component 1 includes several independently arranged position guide plates 11, auxiliary guide plates 12 and inert guide plates 13, and the several position guide plates 11, auxiliary guide plates 12 and inert guide plates 13 are on the same plane.

[0051] The control mechanism 2 includes a gear position control component 21 and an auxiliary control component 22. The gear position control component 21 is connected to the gear position guide plate 11 and the auxiliary guide plate 12 to switch the operating state. The auxiliary control component 22 is connected to the inertia guide plate 13 and can be selectively connected to the auxiliary guide plate 12. When the auxiliary control component 22 is connected to the auxiliary guide plate 12, the auxiliary control component 22 is used to control the enhancement of the operating energy. When the auxiliary control component 22 is connected to the inertia guide plate 13, the operating state is the same as when the gear position control component 21 is connected to the gear position guide plate 11.

[0052] Among them, such as Figure 3-4The production steps of the multi-position control switch include: preparing a conductor 4 that connects several position guide plates 11, auxiliary guide plates 12 and inert guide plates 13; injection molding the conductor 4, forming punch holes 35 at the connection points of the several position guide plates 11, auxiliary guide plates 12 and inert guide plates 13; punching the conductor 4, corresponding to the punch holes 35, punching the connection points to form conductive components 1.

[0053] The gear guide plate 11 refers to a metal sheet structure used to establish the basic gear conduction path. It can be made of copper alloy by stamping, and each gear guide plate 11 corresponds to a specific gear's electrical connection. The auxiliary guide plate 12 refers to an additional conductive path used to enhance operating energy. It can be an independent sheet made of the same material as the gear guide plate 11, forming a parallel circuit to increase current when conducting. The inertial guide plate 13 refers to a neutral conductive path that does not change the original energy output. It can be made using the same process as the auxiliary guide plate 12, maintaining the main gear current parameters when conducting. The gear control component 21 in the control mechanism 2 refers to the mechanical structure that realizes the main gear switching. It can be a rotary contact assembly, selecting different gear guide plates 11 through physical contact. The auxiliary control component 22 refers to an additional energy adjustment module, connecting the auxiliary guide plate 12 or the inertial guide plate 13 through displacement switching. The punching hole 35 in the production step refers to the cutting area reserved during injection molding. It can be a mold forming hole used to guide the stamping tool to cut the connection between the guide plates.

[0054] In this embodiment, the multi-position control switch uses three parallel conductive plates in the conductive component 1, which are formed into independent conductive units through a punching process. When the position control component 21 selects a specific position conductive plate 11, the device enters the basic operating mode. If the auxiliary control component 22 is connected to the auxiliary conductive plate 12, an additional conductive path is formed, increasing the total current and enhancing energy; if it is connected to the inert conductive plate 13, the original current parameters are maintained. This solution directly changes the conductive path through a mechanical structure, reducing circuit complexity. This structure allows the energy regulation function to be independent of position switching. During operation, the output intensity can be adjusted in real time without changing the original speed, achieving dynamic adjustment of operating energy while maintaining the position. In the application of the egg beater, when the user maintains the current speed setting, the whipping force can be temporarily enhanced by switching the auxiliary conductive plate 12. The ability to dynamically adjust whipping parameters according to the characteristics of ingredients and environmental factors avoids sudden changes in the properties of ingredients caused by frequent position changes, further improving the performance of the egg beater, making it highly practical, and effectively ensuring whipping quality.

[0055] In addition, during the production process of the conductive component 1 in the multi-position control switch, after the conductor 4 plate is fixed by injection molding, the cutting position is precisely positioned by the punching hole 35. The conductor 4 is divided into independent position guide plates 11, auxiliary guide plates 12 and inert guide plates 13 by the punching process to ensure that the spacing between each guide plate is uniform and the insulation is reliable.

[0056] The existing production process requires individual processing and assembly of each guide plate 11 for each gear position, which is not only cumbersome but also involves many parts. Compared with the existing technology, this solution adopts a continuous punching process, which effectively reduces assembly errors, reduces processing steps while ensuring the positional accuracy of the guide plates, lowers processing costs and labor time, and correspondingly improves the production efficiency of multi-position control switches.

[0057] Example 2:

[0058] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 5 The auxiliary control component 22 in this embodiment includes a first conductive component 221, a fixing component 224, and a first control component 225.

[0059] The first conductive member 221 is provided with a first connecting end 222 and a second connecting end 223 opposite to each other. The second connecting end 223 is in communication with the inert guide plate 13 or with the auxiliary guide plate 12. The fixing member 224 is provided on both sides of the first connecting end 222 for fixing the first connecting end 222. The first control member 225 abuts against the first conductive member 221 and is provided between the first connecting end 222 and the second connecting end 223 for controlling the second connecting end 223 to be in communication with the inert guide plate 13 or with the auxiliary guide plate 12.

[0060] Specifically, the first conductive element 221 can be formed by stamping an elastic metal sheet, and the conductive path can be switched through deformation.

[0061] The fastener 224 refers to the constraint structure that restricts the displacement of the first connecting end 222. Specifically, it can be a number of positioning posts 217 that surround the first connecting end 222 to achieve the displacement constraint function.

[0062] The first control component 225 refers to the operating component that drives the first conductive component 221 to move. Specifically, it can be a push rod mechanism that changes the shape of the conductive component through mechanical contact. Its function is to precisely control the switching of the second connection end 223.

[0063] In this embodiment, when increased operating energy is required, the first control element 225 pushes the first conductive element 221 to deform, causing the second connection end 223 to disengage from the inert guide plate 13 and contact the auxiliary guide plate 12. At this time, the auxiliary guide plate 12 provides additional energy to the circuit. When the basic energy level needs to be maintained, the external force of the first control element 225 is released, and the first conductive element 221 rebounds, causing the first control element 225 to reset, thereby restoring the contact between the second connection end 223 and the inert guide plate 13. At this time, the energy transmission path remains in its original state. The fixing element 224 clamps and fixes the first connection end 222, ensuring the stability of the first connection end 222 and ensuring that the downward pressure of the first control element 225 causes the second connection end 223 to move, ensuring the smoothness of energy enhancement; it also prevents contact failure due to mechanical vibration during conduction. The abutment position of the first control element 225 is set between the first connection end 222 and the second connection end 223, amplifying the displacement of the control action through the lever principle, ensuring the reliability of conduction switching.

[0064] This application adds an independently controllable auxiliary guide plate 12 conduction path, which adds an energy adjustment dimension while maintaining the gear switching function. This allows the equipment's operating energy to be adjusted in real time according to the actual working conditions, realizing dynamic control of operating energy during gear switching and avoiding the problem of limited equipment performance caused by fixed energy output.

[0065] In kitchen appliance applications, when the whisk is switched to the high-speed setting, the auxiliary guide plate 12 can provide additional energy to accelerate the whisking process; when the ingredients are close to the ideal state, the auxiliary guide plate 12 can be disconnected to reduce energy output and prevent over-whisking. This dynamic adjustment mechanism effectively solves the technical defect of traditional switches where the energy output is not adjustable at fixed settings.

[0066] Preferably, the side of the first control member 225 near the first connection end 222 abuts against the first conductive member 221.

[0067] Here, "abutting" refers to the physical contact formed between the first control element 225 and the first conductive element 221 to transmit force. This contact method can ensure the efficiency of torque transmission.

[0068] Specifically, the first control element 225 contacts the first conductive element 221 near the first connecting end 222, and applies force through this contact point during operation. Since the first connecting end 222 is restricted by the fixing element 224, the first conductive element 221 rotates around this end as a fulcrum, causing the second connecting end 223 to move and disengage from the inertial guide plate 13, contacting the auxiliary guide plate 12. The contact point near the fulcrum forms a short lever arm structure, allowing the small displacement of the first control element 225 to drive the second connecting end 223 to produce a large stroke, thereby ensuring sufficient contact between the first conductive plate and the target guide plate. This structure reduces the elastic deformation of the first conductive element 221 under stress, resulting in a more uniform distribution of contact pressure between the second connecting end 223 and the auxiliary guide plate 12, avoiding increased contact resistance due to localized stress concentration.

[0069] This application significantly improves the displacement accuracy of the second connection end 223 under the same operating stroke by shortening the lever arm length, making the switching action of the conduction state of the auxiliary control component 22 more precise and reliable. In scenarios such as kitchen appliances such as egg beaters that require frequent switching of energy levels, it can effectively avoid energy output fluctuations caused by insufficient contact pressure, ensure stable switching of the whipping function between enhanced and normal levels, and solve the problem of over- or under-whipping of ingredients.

[0070] In some embodiments, see Figure 6-7 The gear control component 21 includes a second conductive piece 211, a conductive shaft 214, a third conductive piece 215, and a second control component 216.

[0071] The second conductive piece 211 is provided with a first contact 212 and a second contact 213. The first contact 212 is connected to the gear guide piece 11, and the second contact 213 is connected to the auxiliary guide piece 12. The central axis of the first contact 212 and the central axis of the second contact 213 coincide. The conductive shaft 214 is movably connected to the other end of the second conductive piece 211. The third conductive piece 215 is connected to the end of the conductive shaft 214 away from the second conductive piece 211 and is used to connect with the wire. The second control member 216 is fixedly connected to the second conductive piece 211, and the conductive shaft 214 passes through the second control member 216 to control the second conductive piece 211 to connect or disconnect with the corresponding gear guide piece 11.

[0072] Specifically, the second conductive piece 211 can be implemented using a double-contact spring sheet formed by stamping copper alloy. The overlapping arrangement of the central axes of its first contact 212 and second contact 213 can ensure uniform distribution of contact pressure.

[0073] The conductive shaft 214 is a component that transmits mechanical motion and maintains a conductive path. Specifically, it can be implemented using a silver-plated metal shaft. Its movable connection design allows the second conductive piece 211 to rotate around the shaft and switch contact positions.

[0074] The third conductive piece 215 refers to the fixed conductive interface for connecting external wires. Specifically, it can be implemented using a riveted terminal block. Its direct connection with the conductive shaft 214 can reduce the contact resistance in the current transmission path.

[0075] The second control component 216 refers to the operating mechanism that drives the second conductive piece 211 to move. Specifically, it can be implemented by a combination structure of injection-molded knob and metal bushing. Its fixed connection through the conductive shaft 214 can ensure the synchronization of movement.

[0076] In this embodiment, when the second control element 216 is rotated, the conductive shaft 214 passing through it drives the second conductive piece 211 to rotate around the shaft, causing the first contact 212 to disengage from the current gear guide piece 11 and move to the target gear guide piece 11 position. Since the central axes of the first contact 212 and the second contact 213 coincide, the second conductive piece 211 maintains contact between the first contact 212 and the gear guide piece 11, and between the second contact 213 and the auxiliary guide piece 12, during rotation, ensuring synchronous contact and stable communication. The movable connection between the conductive shaft 214 and the second conductive piece 211 allows them to form a stable conductive path during rotation. Simultaneously, the third conductive piece 215 connects external wires to the circuit through the conductive shaft 214, ensuring the continuity of the current transmission path. The fixed connection design between the second control element 216 and the second conductive piece 211 eliminates relative displacement between components, ensuring precise correspondence between the contact switching action and the operation input.

[0077] This solution utilizes a double-contact structure with overlapping central axes to ensure that the contact pressure on both sides of the conductive plate remains balanced during rotational switching, effectively eliminating the risk of contact surface misalignment. Furthermore, existing technologies often employ a separate linkage structure between the control component and the conductive plate, which can lead to operational delays due to assembly errors. In contrast, this solution's through-type fixed connection design achieves direct synchronization between the operating mechanism and the conductive component 1, improving the operational accuracy and electrical connection reliability of gear switching, and significantly enhancing switching response accuracy.

[0078] In some embodiments, see Figure 8 The second control component 216 is provided with a positioning post 217 and a limiting block 218. The positioning post 217 passes through the second conductive piece 211, and the limiting block 218 is provided on both sides of the second conductive piece 211.

[0079] The positioning post 217 refers to the columnar structure that penetrates the second conductive piece 211. Specifically, it can be made of metal or engineering plastic into a cylinder, which is used to constrain the second conductive piece 211.

[0080] The limiting block 218 refers to the block-shaped constraint structure set on both sides of the second conductive piece 211. Specifically, it can be implemented by a protruding structure integrally formed with the second control component 216. It maintains a clearance fit with the side of the second conductive piece 211 and is used to limit the displacement of the second conductive piece 211 in the direction perpendicular to the plane of rotation.

[0081] Specifically, the positioning post 217 is inserted into the second conductive piece 211. When the second conductive piece 211 rotates around the conductive shaft 214, the positioning post 217 ensures the stable rotation of the second conductive piece 211, preventing offset and avoiding misalignment with the gear guide piece 11 due to rotation center offset, thus improving the conductivity accuracy between the first contact 212 and the second contact 213 and the guide piece. Limiting blocks 218 are symmetrically distributed on both sides of the second conductive piece 211, forming a 0.1-0.5 mm gap with the sidewall of the second conductive piece 211, allowing for rotational freedom while limiting lateral displacement. During switching, the second conductive piece 211 is doubly constrained by the positioning post 217 and the limiting block 218, restricting its movement trajectory to a single plane of rotation, eliminating unintended swaying caused by mechanical vibration.

[0082] By adding a limiting block 218 to form a double-sided constraint, the motion freedom of the conductive piece is restricted from two-dimensional planar motion to a single rotational motion, effectively reducing the impact of component wear on contact stability. This achieves precise positioning of the second conductive piece 211 during gear switching, ensuring that its contact surface with the gear guide piece 11 always remains completely overlapped. In whisk applications, the operator can obtain a clear sense of gear positioning when rotating the control component, avoiding accidental short circuits or poor contact between different gears due to conductive piece misalignment, resulting in more stable mixing head speed switching and improved uniformity of food whipping.

[0083] In some embodiments, the second control member 216 is provided with a protrusion 219, the upper end of which abuts against the second conductive piece 211 to raise the second conductive piece 211 so as to facilitate rotation.

[0084] The protrusion 219 refers to a local protrusion extending from the surface of the second control element 216. Specifically, it can be an arc-shaped protrusion, a wedge-shaped block, or a cuboid. Its top end forms point contact, line contact, or surface contact with the lower surface of the second conductive piece 211. The tilt angle of the second conductive piece 211 is adjusted by the geometry of the contact surface. The protrusion 219 is positioned between corresponding limiting blocks 218.

[0085] Raising the second conductive piece 211 means applying an upward force to the conductive piece through the protrusion 219, thereby reducing the contact pressure between it and the gear guide piece 11. Specifically, the lifting range can be adjusted by changing the height or tilt angle of the protrusion 219, thereby controlling the friction between the conductive piece and the guide piece.

[0086] Specifically, when the operator rotates the second control component 216, the relative position of the contact area between the tip of the protrusion 219 and the second conductive piece 211 changes. At this time, the protrusion 219 generates an upward lifting force on the conductive piece. This lifting force causes the second conductive piece 211 to deflect slightly around its connection point with the conductive shaft 214, creating a lever effect. During this process, the contact pressure between the second conductive piece 211 and the gear guide piece 11 is partially offset, reducing the sliding friction resistance. At the same time, the deflection trajectory of the second conductive piece 211 is limited to the movement range of the tip of the protrusion 219, ensuring that the conductive piece maintains stable contact with the target gear guide piece 11 after being lifted, avoiding electrical connection failure due to excessive separation.

[0087] This application decomposes the rotational motion into a composite motion of lifting and deflection through the protrusion 219 structure. This reduces friction while maintaining the stability of electrical contact, solves the problem of operation jamming, and achieves low-resistance rotation of the conductive piece during gear switching. It avoids the difficulty of operation caused by excessive friction, while ensuring a reliable electrical connection between the second conductive piece 211 and the conductive piece, thus improving the smoothness of switch operation and service life.

[0088] In some embodiments, the conductive shaft 214 is a hollow conductive shaft 214.

[0089] Among them, the hollow conductive shaft 214 refers to the shaft body with a cavity structure that runs through the axis. Specifically, it can be formed by stamping or cutting metal tubing. The cavity structure reduces the amount of material used and forms a current transmission channel.

[0090] Specifically, the hollow conductive shaft 214 is designed as a tubular structure, with its internal cavity forming a continuous channel along the shaft's extension direction. When the second conductive piece 211 and the third conductive piece 215 are connected to the two ends of the hollow conductive shaft 214 respectively, communication between the second conductive piece 211 and the third conductive piece 215 is achieved. Compared with existing technologies, the traditional conductive shaft 214 uses a solid metal rod structure, which is more bulky and has a higher material cost. In contrast, the hollow structure of the hollow conductive shaft 214 is lighter, and its material cost is much lower than that of a solid shaft. Furthermore, in existing technologies, the heat dissipation of solid shafts relies on external heat sinks, while the cavity of the hollow conductive shaft 214 can form an air convection channel, accelerating the dissipation of heat from the shaft's interior.

[0091] Example 3:

[0092] The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 9The multi-position control switch in this embodiment also includes a housing 3, which is a structure formed by injection molding and curing of the conductor 4. The housing 3 includes a body 31, a movable groove 32, a plurality of first through holes 33, a plurality of second through holes 34 and a plurality of punching holes 35 passing through the body 31. The first through holes 33 are provided corresponding to the position guide plate 11, the second through holes 34 are provided corresponding to the auxiliary guide plate 12, and the punching holes 35 are provided corresponding to the connection points of the plurality of position guide plates 11, auxiliary guide plates 12 and inert guide plates 13. The movable groove 32 is provided corresponding to the second connection end 223.

[0093] Among them, the shell 3 refers to the integrated support structure formed by the injection molding process of the conductor 4 material. Specifically, it can be achieved by injection molding of thermoplastic conductive resin material and then curing it. Its function is to integrate and fix the conductive component 1 with the mechanical structure, eliminating the positioning deviation caused by traditional separate assembly.

[0094] The active groove 32 refers to the recessed area opened on the surface of the shell 3 body 31. Specifically, it can be realized by reserving a groove structure during mold forming. Its function is to provide displacement space for the second connection end 223 of the auxiliary control component 22, so as to realize the connection between the second connection end 223 and the auxiliary guide plate 12 or the inert guide plate 13.

[0095] The first through hole 33 refers to the hole structure that penetrates the body 31 of the shell part 3. Specifically, it can be achieved by setting a corresponding punch in the injection mold to form a hole. Its function is to precisely constrain the installation position of the gear guide plate 11 and ensure that the first contact end 212 enters the first through hole 33 and communicates with the corresponding gear guide plate 11, while ensuring that the spacing between adjacent gear guide plates 11 meets the electrical isolation requirements.

[0096] The second through hole 34 is a through hole that matches the position of the auxiliary guide plate 12. Specifically, it can be achieved by injection molding simultaneously with the first through hole 33. Its function is to fix the auxiliary guide plate 12 and maintain its relative positional relationship with the stop guide plate 11, so as to ensure that the second contact 213 enters the second through hole 34 and communicates with the auxiliary guide plate 12.

[0097] The punching hole 35 refers to the hole-like structure set at the connection of the guide pieces. Specifically, it can be achieved by forming a thin-walled area at the connection of conductor 4 during injection molding. Its function is to provide a precise processing reference point for subsequent punching processes and ensure the reliability of electrical connection between the guide pieces.

[0098] Specifically, after the conductor 4 material is injection molded to form the shell body 31 with through holes and slots, the gear guide 11 is embedded and fixed through the first through hole 33, and the auxiliary guide 12 is positioned and installed through the second through hole 34. The initial connection points between the guides are precisely marked by the punching holes 35. In the subsequent punching process, the cutter cuts off the excess connections between the guides along the edge of the punching holes 35, forming independent conductive circuits. The spatial layout of the movable slot 32 matches the movement trajectory of the second connection end 223 of the auxiliary control component 22. When the control component switches gears, the second connection end 223 moves freely within the range of the movable slot 32, ensuring both freedom of movement and limiting the displacement amplitude through the slot wall. The rigid structure formed by the injection molding of the shell body 31 ensures that each guide maintains a preset spacing and flatness, avoiding poor contact caused by deformation of the guides under stress in traditional assembly.

[0099] This application utilizes the conductor 4 injection molding process to precisely fix the guide piece within the shell 3 through hole during the injection molding stage, eliminating manual assembly errors and achieving precise positioning and installation of the guide piece assembly. This ensures that the spacing error between multiple guide pieces is controlled within the processing accuracy range of the injection mold, avoiding guide piece misalignment caused by manual assembly, and making the production process simple and fast.

[0100] The pre-formed movable groove 32 structure allows for precise reservation of movement space during the injection molding stage, enabling the auxiliary control component 22 to obtain a stable movement trajectory and ensuring smooth component operation. For example, when switching gears in devices such as egg beaters, the auxiliary control component 22 can quickly and reliably contact the inert guide plate 13 or the auxiliary guide plate 12, improving the gear switching response speed.

[0101] The injection-molded punch hole 35 provides a physical machining benchmark, standardizes the punching path, ensures that the flatness of the guide plate edge after punching meets the electrical isolation requirements, and reduces the risk of short circuit.

[0102] The integrated structure of the shell 3 in this application simplifies the production process, and the positioning of the guide plate and the shell forming are completed simultaneously, reducing the cost of manual assembly.

[0103] In some embodiments, the gear guide plate 11 is provided with a first locking hole 111, and the auxiliary guide plate 12 is provided with a plurality of second locking holes 121; the size of the first locking hole 111 is smaller than the size of the first through hole 33, and the size of the second locking hole 121 is smaller than the size of the second through hole 34.

[0104] By making the size of the first locking hole 111 smaller than the size of the first through hole 33, the gear guide plate 11 protrudes from the first through hole 33. When the first contact 212 moves to the first through hole 33, it can conduct with the corresponding gear guide plate 11. Similarly, by making the size of the second locking hole 121 smaller than the size of the second through hole 34, the auxiliary guide plate 12 protrudes from the second through hole 34. When the second contact 213 moves to the second through hole 34, the second contact 213 can conduct with the auxiliary guide plate 12, ensuring that the second conductive plate 211 enters the corresponding through hole after rotation. Specifically, the first contact 212 and the second contact 213 can be implemented using protruding semicircles. This setting allows for precise control of the corresponding gear. Furthermore, by setting the first locking hole 111 and the second locking hole 121, the first contact 212 can be locked into the first locking hole 111, and the second contact 213 can be locked into the second locking hole 121, effectively ensuring the stability of the conduction and ensuring the reliability of the overall operation.

[0105] In some embodiments, the housing 3 further includes a blocking block 36, which is connected to the body 31 and disposed on one side of the second through hole 34. The center point of the blocking block 36 is connected to the center point of the second through hole 34 in an arc shape. The blocking block 36 is used to place the gear control component 21 to disconnect the electrical connection between the gear control component 21 and the conductive component 1.

[0106] Among them, the blocking block 36 refers to the protruding structure connected to the body 31 of the shell 3. Specifically, it can be integrally formed with the shell 3 by injection molding process. Its spatial position is limited to the side of the second through hole 34, and physical isolation is achieved by blocking the contact path between the blocking position control component 21 and the conductive component 1.

[0107] The arc-shaped connection refers to the geometric relationship between the center point of the blocking block 36 and the center point of the second through hole 34. Specifically, the arc parameter can be determined by three-dimensional modeling. This arc matches the gear shifting trajectory to ensure the precise positioning of the blocking block 36 on the rotation path.

[0108] Specifically, the blocking block 36 is integrated into the body 31 of the housing 3 near the second through hole 34, and its arc-shaped positioning feature is coaxial with the rotation axis of the gear control component 21. When the gear control component 21 is switched to a specific position, its bottom structure is guided to the surface of the blocking block 36, at which point the conductive contact surface between the gear control component 21 and the conductive component 1 is completely blocked by the blocking block 36. The solid structure of the blocking block 36 forms a physical barrier, preventing the gear control component 21 from making electrical contact with the auxiliary guide plate 12, thereby disconnecting the circuit. This blocking process does not rely on the deformation and reset of the elastic contact; it directly cuts off the current path through the spatial interference of the rigid structure.

[0109] This solution, through the rigid isolation of the blocking block 36, avoids the arcing and poor contact phenomena caused by contact disconnection, achieving zero-contact control of circuit disconnection during gear switching, ensuring stability in the power-off state, and avoiding the risk of false triggering. Furthermore, its arc-shaped positioning design uses the blocking block 36 as both a physical isolation component and a positioning reference, simplifying the structural layout while ensuring that the blocking block 36 and the conductive component 1 always maintain a predetermined distance, improving the reliability of equipment operation.
