Description

Technical Field

[0001] This application relates to the field of multi-directional switch technology, and in particular to multi-directional switches and electronic devices. Background Technology

[0002] Multi-directional switches, with their ability to operate in multiple directions (center press, up, down, left, and right), are widely used in various electronic devices, such as remote controls and control handles. A multi-directional switch mainly consists of a switch body, a multi-directional tilting push rod, and a reset mechanism. Users can achieve multi-directional operation by pressing the push rod in different directions; after releasing the push rod, the reset mechanism drives the push rod to its original position.

[0003] Conventional multi-way switches generally use metal springs as reset components. During frequent pressing and resetting operations, the metal spring may deform or rub or collide with other components in the multi-way switch (such as the switch body, push rod, etc.), which can easily lead to abnormal noises. Utility Model Content

[0004] Therefore, it is necessary to address the problem that conventional multi-way switches commonly use metal springs as reset components, which can easily lead to abnormal noises during frequent pressing and reset operations. A new multi-way switch and electronic device should be provided.

[0005] This application embodiment provides a multi-directional switch, which is electrically connected to a circuit board. The multi-directional switch includes:

[0006] The switch body has multiple pressable areas, including a central pressable area and multiple peripheral pressable areas arranged around the central pressable area. Pressing different pressable areas can connect different paths on the circuit board.

[0007] A pressing actuator, one end of which is mounted on the switch body, is operable to press any pressed area; and

[0008] The elastic reset element is at least partially made of elastic material, and when the switch body is in the pressed state, the elastic reset element abuts against the pressing transmission element.

[0009] In the aforementioned multi-way switch, at least a portion of the elastic reset element is made of elastic material. When the switch body is in the pressed state, the deformable portion of the elastic reset element abuts against the pressing transmission element. During frequent pressing operations and reset processes, the flexible deformation characteristics of the elastic material on the elastic reset element can be utilized to reduce rigid friction and collisions between the elastic reset element and other components in the multi-way switch. Simultaneously, the elastic reset element itself undergoes flexible deformation, eliminating friction and collision noises, thereby effectively reducing abnormal noise issues during the use of the multi-way switch.

[0010] In one embodiment, the multi-directional switch further includes a support portion for connection to a circuit board, and a resilient reset member is mounted on the support portion.

[0011] In this embodiment, the switch body is connected to the circuit board via a support portion. The support portion supports the elastic reset member. When the switch body is pressed by the pressing actuator, both ends of the elastic reset member contact the support portion and the pressing actuator respectively, and the pressing actuator compresses the deformable portion of the elastic reset member towards the side where the support portion is located.

[0012] In one embodiment, the elastic reset member includes: a reset member body and a plurality of elastic abutment portions, the plurality of elastic abutment portions being connected to one side of the reset member body and arranged around the switch body;

[0013] When the switch body is in the pressed state, the ends of the multiple elastic abutment parts away from the reset body abut against the pressing transmission part, and the side of the reset body facing away from the pressing transmission part abuts against the support part.

[0014] Multiple elastic abutment parts are connected to one side of the reset component body, forming an integral part with the reset component body, thereby facilitating the installation and removal of the elastic reset component. Because the multiple elastic abutment parts are arranged around the switch body, the pressing actuator can be supported by the elastic abutment parts in all circumferential directions, which helps the pressing actuator smoothly return to its initial state.

[0015] In one embodiment, the pressing transmission member includes a pressing body and a circumferential protrusion. One end of the pressing body is connected to the end of the switch body away from the circuit board, and the circumferential protrusion is disposed on the outer peripheral wall of the pressing body and extends along the circumference of the pressing body.

[0016] When the switch body is in the pressed state, the ends of the multiple elastic abutment parts away from the reset body abut against the circumferential protrusions.

[0017] Because the circumferential protrusion extends circumferentially along the outer peripheral wall of the pressing body, an annular end face can be formed. When the switch body is in the pressed state, multiple elastic abutment parts can stably abut against this annular end face, which facilitates the synchronous support of the pressing transmission component by multiple elastic abutment parts, providing it with a reset force, thereby helping the pressing transmission component to return to its initial state stably and smoothly.

[0018] In one embodiment, multiple elastic abutment portions are staggered with multiple peripheral pressed areas along the circumference surrounding the central pressed area.

[0019] By arranging multiple elastic abutment parts and multiple peripheral pressed areas at an angle offset around the central pressed area in the circumferential direction, the problem that the opposite area of ​​the pressing transmission component may disengage from the elastic abutment parts when it tilts toward a certain peripheral pressed area is solved.

[0020] In one embodiment, the support portion is provided with a plurality of mounting holes; the elastic reset member includes:

[0021] The reset component body abuts against the support part on the side facing away from the pressing transmission component;

[0022] Multiple mounting parts are connected to the side of the reset body away from the elastic abutment part, and the multiple mounting parts are respectively engaged with multiple mounting holes.

[0023] Multiple mounting parts and mounting holes mate to connect the reset component body to the support, thereby enabling the elastic reset component to be mounted on the support and minimizing circumferential displacement or flipping of the elastic reset component when the pressing transmission component is activated. Simultaneously, when the pressing transmission component tilts, the mounting part can generate a small elastic deformation within the mounting hole, avoiding rigid interference and thus improving the smoothness and structural reliability of the multi-directional switch reset process.

[0024] In one embodiment, multiple mounting portions are respectively interference-fitted with multiple mounting holes, thereby enabling a more reliable connection between the reset body and the support portion.

[0025] In one embodiment, the cross-sectional area of ​​the mounting portion decreases from large to small along the end of the reset member body away from the elastic abutment portion.

[0026] The end of the mounting part furthest from the elastic abutment has a smaller cross-sectional area, facilitating quick insertion of the mounting part into the mounting hole of the support part, thus providing a guiding function and improving assembly efficiency. Conversely, the end of the mounting part that connects to the reset component has a larger cross-sectional area, ensuring a tight fit between the mounting part and the mounting hole for a reliable connection.

[0027] In one embodiment, the support portion is provided with a plurality of positioning holes;

[0028] The elastic reset component also includes multiple positioning parts connected to one side of the reset component body, and the multiple positioning parts respectively cooperate with multiple positioning holes.

[0029] By cooperating with the positioning part and the positioning hole, the offset of the positioning part can be effectively limited, thereby reliably achieving accurate positioning of the reset body on the support part and preventing circumferential offset of the elastic reset part.

[0030] In one embodiment, the cross-sectional area of ​​the positioning part is larger than that of the mounting part. Because the cross-sectional area of ​​the positioning part is larger than that of the mounting part, the cooperation between the positioning part and the positioning hole can reliably limit the offset of the reset member body, thereby further and sufficiently preventing circumferential offset of the elastic reset member.

[0031] In one embodiment, the length of the mounting portion protruding from the reset member body is greater than the length of the positioning portion protruding from the reset member body.

[0032] Because the protruding length of the mounting part is relatively large, when assembling the elastic reset member with the support part, the mounting part is first assembled into the mounting hole, and then the positioning part enters the positioning hole. In this way, after the mounting part mates with the mounting hole to install the elastic reset member onto the support part, the positioning part mates with the positioning hole to further achieve precise positioning of the reset member body on the support part, preventing circumferential displacement of the elastic reset member.

[0033] One embodiment of this application provides an electronic device, including a circuit board and a multi-directional switch according to any of the above embodiments, wherein the multi-directional switch is electrically connected to the circuit board.

[0034] In the aforementioned electronic device, at least a portion of the elastic reset element is made of elastic material. When the switch body is in a pressed state, the deformable portion of the elastic reset element abuts against the pressing transmission element. During frequent pressing operations and reset processes, the flexible deformation characteristics of the elastic material on the elastic reset element can be utilized to reduce rigid friction and collisions between the elastic reset element and other components in the multi-way switch. Simultaneously, the elastic reset element itself undergoes flexible deformation, eliminating friction and collision noises, thereby effectively reducing abnormal noise problems during the use of the multi-way switch.

[0048] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] Please refer to Figure 1 One embodiment of this application provides a multi-directional switch 10, which is used for electrical connection with a circuit board 20. The multi-directional switch 10 includes: a switch body 100, a pressing transmission member 200, and an elastic reset member 400.

[0050] The switch body 100 has multiple pressable areas, including a central pressable area and multiple peripheral pressable areas arranged around the central pressable area. Pressing different pressable areas can connect different paths on the circuit board 20. A pressing actuator 200 is installed at one end of the switch body 100, and the pressing actuator 200 can be operated to press any of the pressable areas.

[0051] Specifically, different pressed areas correspond to different paths on the circuit board 20. Therefore, when each pressed area is pressed, it can connect to a different path on the circuit board 20. Optionally, multiple pressed areas can be located on the end face of the switch body 100 facing away from the circuit board 20, or on other surfaces of the switch body 100. When using the multi-way switch 10, the pressing actuator 200 can be operated to press the pressing actuator 200 towards the central pressed area or towards any one of the peripheral pressed areas, so that the switch body 100 connects to the corresponding path on the circuit board 20, thereby achieving circuit conduction of that path.

[0052] Understandably, when pressing the central pressed area, the user can press the pressing actuator 200 perpendicularly towards the end face of the switch body 100 away from the circuit board 20. When pressing any peripheral pressed area, the pressing actuator 200 can be tilted towards that peripheral pressed area so that the pressing actuator 200 presses against that peripheral pressed area. After the pressed area receives the pressing force from the pressing actuator 200, the path on the circuit board 20 corresponding to that pressed area can be connected.

[0053] The detailed principles and structure of connecting different pathways on circuit board 20 by pressing each pressed area can be found in existing technology and will not be described in detail here.

[0054] At least a portion of the elastic reset member 400 is made of an elastic material. When the switch body 100 is in a pressed state, the deformable portion of the elastic reset member 400 abuts against the pressing transmission member 200. The deformable portion of the elastic reset member 400 is made of an elastic material.

[0055] The deformable portion of the elastic reset member 400 can be made of materials such as silicone or rubber. Optionally, the entire structure of the elastic reset member 400 may be made of an elastic material. Alternatively, a portion of the structure of the elastic reset member 400 may be made of an elastic material.

[0056] Specifically, in use, the resilient reset member 400 of the multi-directional switch 10 is located between the circuit board 20 and the pressing actuator 200. When the switch body 100 is in an unpressed state (i.e., the initial state where none of the pressed areas are pressed), the resilient reset member 400 and the pressing actuator 200 can either abut against each other or have a slight gap. Thus, when the switch body 100 is pressed by the pressing actuator 200, the pressing actuator 200 simultaneously compresses the resilient reset member 400, causing the resilient reset member 400 to accumulate elastic potential energy. Therefore, after the pressing action is removed and the pressing actuator 200 is released, the reset force of the resilient reset member 400 can drive the pressing actuator 200 back to center and reset, thereby removing the pressure on the pressed areas and disconnecting the corresponding pathways of each pressed area.

[0057] Optionally, when the switch body 100 is in an unpressed state (i.e., the initial state where none of the pressed areas are pressed), the elastic reset member 400 abuts against the pressing transmission member 200 to provide pre-pressure to the elastic reset member 400, so that the deformable part of the elastic reset member 400 is in a slightly compressed state. Thus, after the pressing action is removed, the elastic reset member 400 can provide sufficient and powerful elastic force to the pressing transmission member 200 for resetting when it resets.

[0058] In the aforementioned multi-way switch 10, at least a portion of the elastic reset member 400 is made of elastic material. When the switch body 100 is in a pressed state, the deformable portion of the elastic reset member 400 abuts against the pressing transmission member 200. During frequent pressing operations and reset processes, the flexible deformation characteristics of the elastic material on the elastic reset member 400 can be utilized to reduce rigid friction and collisions between the elastic reset member 400 and other components in the multi-way switch 10 (such as the pressing transmission member, switch body, etc.). At the same time, the elastic reset member 400 itself deforms into a flexible deformation, eliminating friction and collision noises, thereby effectively reducing abnormal noise problems during the use of the multi-way switch 10.

[0059] Traditional multi-way switches use metal springs as reset components. When resetting, the direction of the pressing force differs significantly from the bending direction of the metal spring, and the metal spring has high rigidity. Therefore, the metal spring is prone to bouncing and shaking during reset, resulting in an unstable reset process.

[0060] In this embodiment, the deformable portion of the elastic reset member 400 is made of elastic material, and the deformation of the deformable portion of the elastic reset member 400 is a flexible deformation, with slow and stable deformation during pressing and reset. When the pressing transmission member 200 presses at an angle towards any peripheral pressed area, the direction of the pressing force is basically consistent with the deformation direction of the deformable portion of the elastic reset member 400. Therefore, after the pressing force is removed, the elastic force generated by the elastic reset member 400 is basically sufficient to make the pressing transmission member 200 smoothly return to its initial state in the opposite direction of the original tilt direction, and the reset process is stable.

[0061] Please refer to Figure 1 In one embodiment, the multi-way switch 10 further includes a support portion 300. The support portion 300 is used to connect to the circuit board 20, and the resilient reset member 400 is mounted on the support portion 300.

[0062] The support part 300 can be connected or fixed to the circuit board 20 by means of bolts, clips, or other methods. The material used for the support part 300 can be plastic or PVC, and there is no limitation on it.

[0063] In this embodiment, the support portion 300 is connected to the circuit board 20. The support portion 300 supports the elastic reset member 400, which is located between the support portion 300 and the pressing transmission member 200. Thus, when the switch body 100 is pressed by the pressing transmission member 200, both ends of the elastic reset member 400 contact the support portion 300 and the pressing transmission member 200 respectively, and the pressing transmission member 200 compresses the deformable portion of the elastic reset member 400 towards the side where the support portion 300 is located.

[0064] In one embodiment, the multi-directional switch 10 is a five-way switch, meaning that the number of peripheral pressed areas is four.

[0065] Optionally, multiple peripheral pressing areas are evenly distributed circumferentially around the central pressing area. When there are four peripheral pressing areas, that is, the four peripheral pressing areas are distributed at 90° intervals, and in terms of the user's position during operation, the four peripheral pressing areas are distributed in the four directions of up, down, left, and right.

[0066] In other embodiments, the number of peripheral pressed areas can also be two, three, or other numbers, which can be flexibly set according to needs.

[0067] Please combine Figures 1 to 4 In one embodiment, the resilient reset member 400 includes a reset member body 410 and a plurality of resilient abutment portions 420. The plurality of resilient abutment portions 420 are connected to one side of the reset member body 410 and arranged around the switch body 100. In the resilient reset member 400, at least the resilient abutment portions 420 are made of an elastic material.

[0068] When the switch body 100 is in the pressed state, the ends of the multiple elastic abutment portions 420 away from the reset member body 410 abut against the pressing transmission member 200, and the side of the reset member body 410 facing away from the pressing transmission member 200 abuts against the support portion 300.

[0069] When the switch body 100 is in an unpressed state, the end of the elastic abutment portion 420 away from the reset member body 410 can abut against the pressing transmission member 200, or it can have a slight gap. Thus, when the switch body 100 is pressed by the pressing transmission member 200, the pressing transmission member 200 simultaneously compresses the end of the elastic abutment portion 420 away from the reset member body 410, while the side of the reset member body 410 facing away from the pressing transmission member 200 abuts against the support portion 300, allowing the elastic abutment portion 420 to accumulate elastic potential energy. After the pressing action is removed, the restoring force of the elastic abutment portion 420 can drive the pressing transmission member 200 back to its initial state.

[0070] Specifically, when the pressing transmission member 200 presses vertically downward toward the central pressed area, multiple elastic abutment parts 420 are compressed synchronously; when the pressing transmission member 200 presses at an angle toward any peripheral pressed area, the elastic abutment parts 420 located near the peripheral pressed area bear the main compressive force. After the pressing force is removed, the elastic abutment parts 420 and the reset member body 410 use their accumulated elastic potential energy to push the pressing transmission member 200 back to its initial state.

[0071] In this embodiment, multiple elastic abutment portions 420 are connected to one side of the reset member body 410, forming an integral part with the reset member body 410, thereby facilitating the installation and removal of the elastic reset member 400.

[0072] Since multiple elastic abutment portions 420 are arranged around the switch body 100, the pressing transmission member 200 can be supported by the elastic abutment portions 420 in all circumferential directions, which is conducive to the pressing transmission member 200 returning to the initial state smoothly.

[0073] In one embodiment, the elastic abutment portion 420 and the reset body 410 are integrally formed (which can be integrally formed by a mold). Since the elastic abutment portion 420 and the reset body 410 are integrally formed, they have good coordination during deformation, which is conducive to the elastic reset member 400 achieving smooth reset without jamming and reducing rigid friction between components.

[0074] The reset body 410 and the elastic abutment part 420 can also be a structure that is connected after being separately molded.

[0075] The reset body 410 and the elastic contact part 420 can be made of the same material or different materials.

[0076] Optionally, the reset body 410 is made of an elastic material.

[0077] In one embodiment, the plurality of resilient abutment portions 420 may be evenly distributed along the direction surrounding the switch body 100.

[0078] Understandably, the direction of the multiple elastic abutment portions 420 around the switch body 100 is the same as the direction of the multiple peripheral pressed areas around the central pressed area.

[0079] When there are four elastic abutment portions 420, the four elastic abutment portions 420 are distributed at 90° intervals. The number of elastic abutment portions 420 can also be two, three, five, or other numbers.

[0080] Please combine Figures 1 to 4 In one embodiment, the reset body 410 is provided with a first clearance hole 411, and the end of the switch body 100 away from the circuit board 20 passes through the first clearance hole 411 and is connected to the pressing transmission member 200. By providing the first clearance hole 411 on the reset body 410, interference between the reset body 410 and the switch body 100 is avoided, and the connection between the switch body 100 and the pressing transmission member 200 is facilitated.

[0081] Please combine Figures 1 to 3 In one embodiment, the pressing transmission member 200 includes a pressing body 210 and a circumferential protrusion 220. One end of the pressing body 210 is connected to the end of the switch body 100 away from the circuit board 20. The circumferential protrusion 220 is disposed on the outer peripheral wall of the pressing body 210 and extends circumferentially along the pressing body 210.

[0082] When the switch body 100 is in the pressed state, the ends of the multiple elastic abutment portions 420 away from the reset member body 410 respectively abut against the circumferential protrusions 220.

[0083] In this embodiment, each pressed area on the switch body 100 can be pressed by pressing the pressing body 210. Since the circumferential protrusion 220 extends circumferentially along the outer peripheral wall of the pressing body 210, an annular end face can be formed. When the switch body 100 is in the pressed state, the multiple elastic abutment portions 420 can stably abut against the annular end face, which facilitates the multiple elastic abutment portions 420 to synchronously support the pressing transmission member 200 and provide it with a reset force, thereby helping the pressing transmission member 200 to return to its initial state stably and smoothly.

[0084] In one embodiment, multiple elastic abutment portions 420 are arranged in a staggered manner with multiple peripheral pressed areas along the circumference surrounding the central pressed area.

[0085] By arranging multiple elastic abutment portions 420 and multiple peripheral pressed areas at an angle offset around the central pressed area in the circumferential direction, the problem that the opposite area of ​​the pressing transmission member 200 may disengage from the elastic abutment portion 420 when it tilts toward a certain peripheral pressed area is solved.

[0086] For example, if a peripheral pressing area is provided on the left and right sides of the switch body 100, and an elastic abutment 420 is provided on the elastic reset member 400 corresponding to the two peripheral pressing areas, when force is applied to the left peripheral pressing area, the pressing transmission member 200 will tilt to the left. At this time, the right side of the pressing transmission member 200 will be lifted due to the tilt, causing the elastic abutment 420 corresponding to the right pressing area to easily disengage from the pressing transmission member 200.

[0087] However, in this embodiment, for each peripheral pressed area, the elastic abutment portion 420 is distributed at a certain angle offset circumferentially from the peripheral pressed area. When force is applied to the left peripheral pressed area, the pressing transmission member 200 tilts to the left. Although the pressing transmission member 200 is raised at the corresponding position of the right peripheral pressed area, because the elastic abutment portion 420 is misaligned with this position, it will not completely disengage due to the tilt of the pressing transmission member 200, and can still maintain a partial abutment state, thereby continuously providing a restoring force.

[0088] Optionally, when there are four elastic abutment portions 420 and four peripheral pressed areas, the misalignment angle between the elastic abutment portions 420 and the circumferentially adjacent peripheral pressed areas can be 45°.

[0089] Please combine Figure 1 , Figures 4 to 6In one embodiment, the support portion 300 is provided with a plurality of mounting holes 312. The elastic reset member 400 includes a reset member body 410 and a plurality of mounting portions 430.

[0090] The reset body 410 abuts against the support portion 300 on the side facing away from the pressing transmission member 200. A plurality of mounting portions 430 are connected to the side of the reset body 410 facing away from the elastic abutment portion 420, and the plurality of mounting portions 430 respectively mate with a plurality of mounting holes 312.

[0091] In this embodiment, multiple mounting portions 430 respectively cooperate with multiple mounting holes 312 to connect the reset member body 410 and the support portion 300, thereby enabling the elastic reset member 400 to be mounted on the support portion 300 and minimizing circumferential displacement or flipping of the elastic reset member 400 when the pressing transmission member 200 is activated. Simultaneously, when the pressing transmission member 200 tilts, the mounting portion 430 can undergo a small elastic deformation within the mounting hole 312, avoiding rigid interference and thus improving the smoothness and structural reliability of the multi-directional switch 10's reset process.

[0092] The reset body 410 and the mounting part 430 can be integrally formed or they can be separately formed and then connected. The reset body 410 and the mounting part 430 can be made of the same material or different materials.

[0093] Optionally, multiple mounting parts 430 are respectively interference-fitted with multiple mounting holes 312 to achieve a reliable connection between the reset body 410 and the support part 300.

[0094] Optionally, the mounting part 430 is made of an elastic material.

[0095] In other embodiments, the mounting part and the mounting hole can also be fitted by other fitting methods such as riveting.

[0096] Please combine Figure 1 , Figure 5 In one embodiment, along the end of the reset member body 410 away from the elastic abutment portion 420, the cross-sectional area of ​​the mounting portion 430 decreases from large to small.

[0097] Specifically, with the longitudinal direction of the mounting portion 430 protruding from the resetting member body 410 as the longitudinal direction, the cross section of the mounting portion 430 is perpendicular to the protrusion direction.

[0098] The end of the mounting part 430 furthest from the elastic abutment part 420 has a smaller cross-sectional area, which facilitates the quick insertion of the mounting part 430 into the mounting hole 312 of the support part 300, thus providing a guiding function and improving assembly efficiency. The end of the mounting part 430 connected to the reset body 410 has a larger cross-sectional area, which allows for a tight fit between the mounting part 430 and the mounting hole 312 to form a reliable connection.

[0099] Please refer to Figure 5 In one embodiment, the mounting portion 430 includes a first segment 431, a second segment 432, and a transition segment 433. The first segment 431 is connected to the reset body 410, and the two ends of the transition segment 433 are connected to the second segment 432 and the first segment 431, respectively. From the first segment 431 towards the second segment 432, the cross-sectional area of ​​the transition segment 433 gradually decreases. The cross-sectional area of ​​the first segment 431 is larger than the cross-sectional area of ​​the second segment 432.

[0100] The second segment 432 has a smaller cross-sectional area and serves as a guide, facilitating quick insertion into the mounting hole 312 of the support 300. The gradient structure of the transition segment 433 forms a smooth guide surface, facilitating the insertion of the first segment 431 into the mounting hole 312. The first segment 431 has a larger cross-sectional area, fitting tightly with the wall of the mounting hole 312 to form a reliable connection.

[0101] Please combine Figures 4 to 6 In one embodiment, the support portion 300 is provided with a plurality of positioning holes 313. The elastic reset member 400 also includes a plurality of positioning portions 440 connected to one side of the reset member body 410, and the plurality of positioning portions 440 respectively cooperate with the plurality of positioning holes 313.

[0102] Specifically, the positioning part 440 is connected to the side of the reset body 410 away from the elastic abutment part 420, that is, the positioning part 440 and the mounting part 430 are located on the same side of the reset body 410.

[0103] By cooperating with the positioning part 440 and the positioning hole 313, the offset of the positioning part 440 can be effectively limited, thereby reliably achieving accurate positioning of the reset body 410 on the support part 300 and preventing the elastic reset part 400 from shifting circumferentially.

[0104] In one embodiment, the length of the mounting portion 430 protruding from the reset member body 410 is greater than the length of the positioning portion 440 protruding from the reset member body 410.

[0105] Specifically, because the protruding length of the mounting portion 430 is relatively large, when assembling the elastic reset member 400 with the support portion 300, the mounting portion 430 is first assembled into the mounting hole 312, and then the positioning portion 440 enters the positioning hole 313. Thus, after the mounting portion 430 engages with the mounting hole 312 to install the elastic reset member 400 onto the support portion 300, the engagement of the positioning portion 440 with the positioning hole 313 further ensures precise positioning of the reset member body 410 on the support portion 300, preventing circumferential displacement of the elastic reset member 400.

[0106] Optionally, the multiple positioning parts 440 are respectively interference-fitted with the multiple positioning holes 313 to achieve a more reliable connection.

[0107] Optionally, the positioning part 440 is made of an elastic material.

[0108] In one embodiment, the cross-sectional area of ​​the positioning part 440 is larger than the cross-sectional area of ​​the mounting part 430.

[0109] Similar to the cross-section of the mounting portion 430, for the positioning portion 440, with the protrusion direction of the positioning portion 440 protruding from the reset member body 410 as the longitudinal direction, the cross-section of the positioning portion 440 is perpendicular to the protrusion direction. It can be understood that in this embodiment, the protrusion direction of the positioning portion 440 protruding from the reset member body 410 is parallel to the protrusion direction of the mounting portion 430 protruding from the reset member body 410.

[0110] Since the cross-sectional area of ​​the positioning part 440 is larger than that of the mounting part 430, the cooperation between the positioning part 440 and the positioning hole 313 can reliably limit the offset of the reset member body 410, thereby further preventing the circumferential offset of the elastic reset member 400.

[0111] The reset body 410 and the positioning part 440 can be integrally formed or they can be separately formed and then connected. The reset body 410 and the positioning part 440 can be made of the same material or different materials.

[0112] Multiple positioning holes 313 can be evenly distributed along the circumference of the support 300. For example, there may be four, three, or other similar holes.

[0113] Further, please refer to Figure 6 The positioning hole 313 is located at the edge of the second clearance hole 311 and communicates with the second clearance hole 311. The positioning hole 313 forms a notch structure at the edge of the second clearance hole 311.

[0114] Please refer to Figure 5 In one embodiment, one end of the pressing transmission member 200 is provided with a first mounting hole 201, which engages with one end of the switch body 100.

[0115] Furthermore, the side wall of the first mounting hole 201 is provided with a positioning protrusion 211, and the switch body 100 is provided with a positioning groove 101 that mates with the positioning protrusion 211. By cooperating with the positioning protrusion 211 and the positioning groove 101, a reliable engagement between the pressing transmission component 200 and the switch body 100 can be achieved.

[0116] Please combine Figure 1 , Figure 5 and Figure 6In one embodiment, the support portion 300 includes a support plate 310 and a side support member 320. The side support member 320 surrounds the support plate 310 and is connected to the circumferential edge of the support plate 310. The side support member 320 is used to fix the circuit board 20.

[0117] The support plate 310 is provided with a second clearance hole 311. The end of the switch body 100 away from the circuit board 20 passes through the second clearance hole 311 and is connected to the pressing transmission member 200. The side of the reset member body 410 facing away from the pressing transmission member 200 abuts against the support plate 310.

[0118] Specifically, the side support 320 and the circuit board 20 can be fixed by means of bolt connection, snap-fit ​​connection or other methods.

[0119] The side support 320 may be wrapped around the support plate 310 in the circumferential direction to form an annular side plate structure.

[0120] The second clearance hole 311 on the support plate 310 provides a through channel for the end of the switch body 100 away from the circuit board 20, so as to avoid the support plate 310 interfering with the connection between the switch body 100 and the pressing transmission member 200. At the same time, the reset member body 410 can abut against the flat support surface of the support plate 310 to ensure reliable and stable abutment and ensure stable reset force.

[0121] Please refer to Figure 1 , Figure 3 as well as Figure 5 In one embodiment, the multi-directional switch 10 further includes a push cap 500, which is connected to the end of the push transmission member 200 away from the switch body 100. The push cap 500 facilitates user operation.

[0122] In one embodiment, the end of the pressing transmission member 200 away from the switch body 100 is provided with a second mounting hole 202, and one end of the pressing cap 500 is engaged with the second mounting hole 202. The second mounting hole 202 is a non-circular hole.

[0123] The end of the press cap 500 that is inserted into the second assembly hole 202 has a non-circular outer contour, which can prevent mistaken assembly of the press cap 500.

[0124] An embodiment of this application also provides an electronic device, including a circuit board 20 and a multi-way switch 10 of any of the above embodiments, wherein the multi-way switch 10 is mounted on the circuit board 20.
