Description

Technical Field

[0001] The invention relates to the field of switches, and in particular to a switch with a shell anti-restart mechanism and a use method thereof. Background Art

[0002] The start switch is a common switch in daily life, usually used for starting cars, equipment or other ignition devices. The start switch is normally designed with different switch positions, and the selection of different switch positions is to select the control switch position by rotating the switch at different center angles.

[0003] During the research and development process, the inventors found that in the prior art, a torsion spring is usually used in the start switch to complete its rotation angle, and the torsion spring is stretched or squeezed after rotation. When the rotation traction disappears, the torsion spring will rotate back and forth like a pendulum due to deformation, and this rotation brings instability risks to the switch gear connection. More importantly, when the switch is in the start state, it will start again due to the pendulum-like rotation, and the device using the switch may receive a feedback signal due to the restart, and then an erroneous indication or execution of an erroneous instruction will occur, causing inconvenience to the user and even a safety hazard.

[0056] In one embodiment of the present invention, in combination with the attached Figure 1 and attached Figure 2 As shown, a switch with a shell anti-restart mechanism comprises a switch head 1, a nut 2, a switch shell 3, an action module 4, a pin seat 5 and a bottom cover 6, wherein the switch head 1 acts on the action module 4, the switch shell 3, the action module 4, the pin seat 5 and the bottom cover 6 are connected in sequence, the nut 2 is fastened on the switch shell 3, at least one shell anti-restart mechanism 7 is arranged in the switch shell 3, and a rotating piece 8 is arranged on the action module 3, and the rotating piece 8 cooperates with the shell anti-restart mechanism 7 to brake the action module 4. In this embodiment, through the innovative design of the shell anti-restart mechanism and the rotating piece, the cooperation between the shell anti-restart mechanism and the rotating piece is utilized to realize rigid braking of the pendulum-like rotation of the action module, which can prevent the action module from having a new pendulum-like rotation due to braking, thereby driving the moving contact piece under the action module to move; at the same time, the rotating piece directly acts on the action module, thereby realizing linkage braking of the action module, and the structure is simple and easy to realize.

[0057] In one embodiment of the present invention, as shown in the attached Figure 3 As shown, the shell anti-restart mechanism 7 is a semi-open opening module, and the semi-open opening is unilaterally oblique. In this embodiment, the shell anti-restart mechanism is designed to cooperate with the rotating piece, and when the rotating piece enters the shell anti-restart mechanism, it can have a one-way carding effect on the rotating piece, thereby preventing the action module from pendulum-like motion and reversing back to the switch position.

[0058] In one embodiment of the present invention, as shown in the attached Figure 3 As shown, the housing anti-restart mechanism includes a first limit block 9 and a second limit block 10; wherein the first limit block 9 is an arc block, the second limit block 10 is an arc block, and the first limit block 9 and the second limit block 10 form an "eight" shape. In this embodiment, the arc design of the limit block can be closely attached to the inner ring wall of the switch housing, thereby not affecting the normal rotation operation between the switch housing and the action module.

[0059] In one embodiment of the present invention, as shown in the attached Figure 3As shown, the outer arc surface of the arc block is fixed to the inner ring wall 11 of the switch housing; the inner side of the arc block is a curved surface; the upward-viewing surface of the arc block is a plane and is fixed to the edge of the upward-viewing surface of the switch housing; the top-viewing surface of the arc block is an inclined surface with a slope. In this embodiment, the outer side surface of the arc block is an outer arc surface so that it can better fit on the inner ring wall of the switch housing, and the upward-viewing surface of the arc block with a flat design makes it simple, convenient and easy to implement when fixing, and the top-viewing surface of the arc block is an inclined surface with an inclined slope. The slope design enables the rotating piece to slide normally above the arc block under the normal action of traction, and the upward-viewing surface of the arc block is a plane so that it can be seamlessly fitted with the upward-viewing surface of the switch housing, so as to achieve better molding or installation.

[0060] In one embodiment of the present invention, in combination with the attached Figure 3 and attached Figure 4 As shown, the arc block includes a raised end and a grounded end; wherein, the first limit block 9 includes a first raised end 12 and a first grounded end 13, and the second limit block 10 includes a second raised end 14 and a second grounded end 15. In this embodiment, the raised end has a certain height, and after installation, the raised end is significantly higher than the upward-looking surface of the switch housing; the grounded end is closely attached to the upward-looking surface of the switch housing, and the end of the grounded end is integrated with the upward-looking surface of the switch housing; through the design of the raised end and the grounded end, the housing anti-restart mechanism can be more closely attached to the housing, and the rotating piece can slide more smoothly on the housing anti-restart mechanism, reducing the friction or resistance when the components interact with each other.

[0061] In one embodiment of the present invention, as shown in the attached Figure 4 As shown, the first protruding end 12 is connected to the side of the second protruding end 14; wherein, the relative side width of the first protruding end 12 is smaller than the relative side width of the second protruding end 14, and the relative side height of the first protruding end 12 is greater than the relative side height of the second protruding end 14. In this embodiment, by using the connection between the protruding ends, the two ends of the shell anti-restart mechanism can be grounded ends, which facilitates the rotation piece to pass through the shell anti-restart mechanism; the height difference between the protruding ends can prevent the rotation piece from directly reaching the starting position when it rotates due to the pendulum-like rotation, but is blocked by the first protruding end from falling into the corner groove.

[0062] In one embodiment of the present invention, in combination with the attached Figure 3 and attached Figure 4As shown, the first protruding end 12 and the side surface of the second protruding end 14 are connected relative to each other to form an angle groove 16. In this embodiment, one side of the angle groove is the inner curved surface of the first limit block. After the first limit block and the second limit block are connected, an angle groove is formed. The width difference between the first protruding end and the second protruding end gives the angle groove an inlay effect, and then the rotating piece is directly embedded in the angle groove after the rotation, and is locked by the angle groove; the rotating piece can slide out of the angle groove by moving along the inner curved surface of the first limit block; the angle groove can not only block the stuck rotating piece when the rotating piece moves in the forward direction again, but also further block the action module from rotating in the forward direction again, and can achieve the effect of shifting again.

[0063] In one embodiment of the present invention, as shown in the attached Figure 3 As shown, the housing anti-restart mechanism is located at an angle between the inner ring wall 11 of the switch housing and the upward-viewing surface 17 of the switch housing. In this embodiment, the housing anti-restart mechanism is disposed between the inner ring wall of the switch housing and the upward-viewing surface of the switch housing, so as to avoid unnecessary obstruction of the action module during the rotation process by the existence of the housing anti-restart mechanism; the effect of the components is optimized, and the beneficial effect of the housing anti-restart mechanism is highlighted.

[0064] In one embodiment of the present invention, in combination with the attached Figure 2 and attached Figure 3 As shown, the switch housing 3 further includes at least four bead grooves 18, a stop block 19 and a stop pin block 35; wherein the bead grooves 18 are arranged in an annular shape around the upper surface 17 of the switch housing, and two adjacent bead grooves 18 have equal center angles. In this embodiment, the center of rotation of the action module is positioned by setting the bead grooves and the stop blocks. The bead grooves are the moving positions of the action module during the rotation process, and the adjacent bead grooves are arranged with the same center angle to facilitate the gear adjustment control.

[0065] In one embodiment of the present invention, in combination with the attached Figure 2 and attached Figure 5 As shown, balls 20 are provided on both sides of the top view of the action module 4, a rotating seat 21 is provided in the middle of the top view of the action module 4, a large torsion spring 22 is wound around the rotating seat 21 and installed inside the action module 4, one end of the large torsion spring 22 is fixed on the action module 4, and the other end of the large torsion spring 22 is a protruding end 23 located at the edge of the top view of the action module 4. In this embodiment, the balls and the ball grooves in the action module are used in coordination with each other to realize convenient positioning of the action module after rotation; at the same time, the design of the large torsion spring enables the action module to realize clockwise and counterclockwise rotation in the same plane, and the protruding end of the large torsion spring cooperates with the limit block, which also plays a fixing role in the positioning of the action module.

[0066] In one embodiment of the present invention, in combination with the attached Figure 2 , Attachment Figure 5 And attached Figure 7 As shown, the rotating piece 8 is semi-rigidly connected to the rotating seat 21, a moving contact piece 24 is arranged below the rotating seat 21, a fixed contact piece 25 is arranged above the pin seat 5, and a terminal 26 is arranged below the pin seat 5; wherein, one end of the rotating piece 8 is a free end 27, and one end of the rotating piece 8 is a fixed end 28, and the fixed end 28 is fixed to the rotating seat 21. In this embodiment, as a preferred embodiment, the free end of the rotating piece has a convex angle, and the corners of the free end are in an arc shape; the free end of the rotating piece is embedded in the angle groove, thereby achieving a braking effect on the action module; the moving contact piece and the fixed contact piece enable the switch to achieve on-off control, preventing the action module from pendulum-like rotation and affecting the movement of the moving contact piece below it, thereby affecting the on-off of the switch contacts or the reconnection after on-off, and then the restart phenomenon occurs.

[0067] In one embodiment of the present invention, as shown in the attached Figure 5 As shown, the semi-rigid connection is that the fixed end 28 is fixed to the rotating seat 21 by a rivet 29 and a small torsion spring 30; wherein the small torsion spring 30 is centered on the rivet 29 and is trapped in the nail column of the rivet 29. In this embodiment, the fixed end of the rotating piece is fixed by a rivet and a small torsion spring, so that the fixed end can rotate the free end of the rotating piece without changing its position, and the force difference between the torsional restoring force of the large torsion spring and the elastic force of the small torsion spring in the action module is used to realize the small torsion spring sliding into the angle groove after recovery; and the semi-rigid connection of the fixed end is to fix the rotating piece on the rotating seat by a linking method, and the small torsion spring and the rivet are used to achieve this linking method, so that the rotating piece can be squeezed by the inner ring wall of the switch housing during normal rotation without hindering the action module; and when the action module rotates forward again, the action module can be effectively braked.

[0068] In one embodiment of the present invention, in combination with the attached Figure 2 , Attachment Figure 5 And attached Figure 6As shown, the action module 4 may also include an O-ring 34, a ball spring 33, a moving contact spring 32 and a stop pin 31; wherein the O-ring 34 acts on the rotating seat 21, the ball spring 33 is used to cushion the ball 20, and the moving contact spring 32 is connected to the moving contact 24. In this embodiment, as a preferred embodiment, adding an O-ring to the action module can make the entire action module structure more compact, and the components in the action module are not easy to shift; the existence of the ball spring can make the ball move more flexibly and slide more easily during the gear shifting process; the moving contact spring not only connects the moving contact, but also makes the moving contact flexible during the movement; the stop pin body cooperates with the stop pin block to realize the unilateral rotation of the control action module.

[0069] In another embodiment of the present invention, a method for using a switch with a shell anti-restart mechanism is provided. According to the gear selection, the rotation angle of the switch with the shell anti-restart mechanism is selected. The switch head starts to rotate from the starting position to the position corresponding to the gear and stops rotating. While completing the switch gear connection, the shell anti-restart mechanism is used to prevent the pendulum movement of the action module. In this embodiment, the shell anti-restart mechanism is used to prevent the pendulum movement of the action module, and the connection operation of the switch is controlled in a one-movement-all-movement manner, so as to avoid the displacement of the moving contact piece after the switch gear is connected, thereby causing the switch to restart, which brings safety hazards to users or downstream installation equipment.

[0070] In another embodiment of the present invention, the switch head starts to rotate from the starting position to the position corresponding to the gear position and stops rotating, that is, during the rotation of the switch head, the action module is synchronously adjusted to rotate at the same angle as the switch head, and the secondary synchronous traction acts on the rotating piece and the moving contact piece of the action module. In this embodiment, the action module is controlled by the switch head for the first linkage, and the rotation control between the action module and the rotating piece and the moving contact piece is the second linkage control. The method of combining multi-level linkage control modes avoids adding use steps, making the use method simple and easy to implement.

[0071] In another embodiment of the present invention, the synchronously adjusted traction action module rotates at the same angle as the action module, and the ball of the action module rolls from the ball groove at the starting position into the ball groove at the corresponding position of the gear, and the upper part of the action module is clamped in the ball groove at the corresponding position of the gear. In this embodiment, during the movement of the action module, the position of the action module is basically fixed by the ball above it and the ball groove at the corresponding position on the shell.

[0072] In another embodiment of the present invention, the switch gear connection is completed, and the movable contact piece contacts the gear fixed contact piece after rotating to complete the switch gear connection. In this embodiment, a movable contact piece rigidly connected to the action module is used. After the action module moves, the movable contact piece moves synchronously with it and reaches the fixed contact piece position on the switch gear, and contacts with it to achieve the switch gear connection.

[0073] In another embodiment of the present invention, the pendulum-like motion of the action module is stopped by the shell anti-restart mechanism. When the action module starts to move in a pendulum-like manner, the rotating piece rotates in the opposite direction and slides into the corner groove of the shell anti-restart mechanism to complete the braking mode. In this embodiment, the shell anti-restart mechanism is introduced and the rotating piece is used to cooperate with it, thereby realizing the linkage start-up control of the shell anti-restart mechanism, and at the same time avoiding the restart problem of the switch gear connection due to the pendulum-like motion of the action module; the completion of the braking mode limits the pendulum-like motion of the middle and lower parts of the action module, so that the rotating piece cannot automatically slide off the corner groove restriction of the shell anti-restart mechanism, and the semi-rigid connection between the rotating piece and the action module can control the restriction of the action module.

[0074] In another embodiment of the present invention, the method for using a switch with a shell anti-restart mechanism further includes that when reselecting a gear, the switch head rotates back to the starting position to restart a new gear selection operation. In this embodiment, the re-shifting operation or restarting operation can be achieved by controlling the reverse rotation of the switch head, so that the method for using the switch with the shell anti-restart mechanism does not increase the number of operating steps due to the increase in functionality, and the method for using is simple, convenient, and easy to implement, and even easy to understand implementation steps, without limiting the user's level.

[0075] In another embodiment of the present invention, the switch head rotates back to the starting position, the action module rotates back to the starting position under the traction of the switch head, and the rotating piece slides out of the angle slot synchronously, returns to the starting position and releases the braking mode of the action module. In this embodiment, the braking mode of the action module can be released by rotating the switch head, so that the use method is simple to operate, has strong linkage, wide applicability, and reliable and safe performance.

[0076] The main principles used in the present invention are as follows. Figure 2 , Attachment Figure 3 , Attachment Figure 5 And attached Figure 7The product of the present invention is that the switch head 1 is rigidly connected to the rotating seat 21 of the action module 4, and the switch housing 3, the pin seat 5, and the bottom cover 6 are rigidly connected. When the switch head 1 rotates, it synchronously drives the action module 4, so that the moving contact piece 24 below the action module 4 rotates synchronously, and contacts and connects with the fixed contact piece 25 on the pin seat 5 in coordination with the rotation control angle to realize the connection of the switch; and the switch housing 3, the pin seat 5, and the bottom cover 6 are rigidly connected to form a whole, and are stationary relative to the action module 4. The ball 20 and the protruding end 23 of the large torsion spring realize point-type fixation of the upper part of the action module 4, and the housing anti-restart mechanism 7 and the rotating piece 8 are innovatively developed, and the housing anti-restart mechanism 7 is used to make a one-way card on the rotating piece 8 to avoid the occurrence of pendulum-like motion of the action module 4; at the same time, the rotating piece 8 and the action module 4 are semi-rigidly connected, and the inherent characteristics of the semi-rigid connection can realize both rotation and a certain degree of bending. The semi-rigid connection enables the rotating piece 8 and the action module 4 to have a synchronous action effect, and the rotating piece 8 can generate a certain degree of curvature and slide into the shell anti-restart mechanism 7 during the reversal process due to stopping. When the action module 4 rotates clockwise, the rotating piece 8 also rotates clockwise, and the large torsion spring 22 in the action module 4 is twisted clockwise, while the switch shell 3 is stationary relative to the action module 4 at this time; the protruding end 23 of the large torsion spring 22 is stuck in the blocking block 19 at the edge of the switch shell 3. When the action module 4 stops rotating, the large torsion spring 22 gives the action module 4 a counterclockwise restoring force to make the action module 4 rotate back, that is, rotate counterclockwise, causing the free end 27 of the rotating piece 8 to slide into the angle slot 16 of the shell anti-restart mechanism 7. During the process of the action module 4 rotating clockwise until it stops, the free end 27 of the rotating piece 8 slides clockwise along the inner ring wall 11 of the switch housing, passing the housing anti-restart mechanism 7. During the friction and sliding process, the small torsion spring 30 at the fixed end of the rotating piece 8 continuously generates a counterclockwise twisting force. When the large torsion spring 22 pulls back the action module 4, the small torsion spring 30 generates a clockwise restoring force due to the disappearance of the counterclockwise friction and sliding. Under the reverse force interaction with the counterclockwise restoring force of the large torsion spring 22, the rotating piece 8 is twisted and a distance is generated from the inner ring wall 11 of the switch housing, and then the rotating piece 8 slides into the angle groove 16.

The first raised end 12 and the side surface of the second raised end 14 are connected to each other to form an angle groove 16. The housing anti-restart mechanism is located at the angle between the inner ring wall 11 of the switch housing and the upward-viewing surface 17 of the switch housing. The switch housing 3 further includes six bead grooves 18, a positioning block 19 and a limiting pin block 35; wherein the bead grooves 18 are annularly arranged around the top-view surface 17 of the switch housing, and the center angles of two adjacent bead grooves 18 are equal. Balls 20 are arranged on both sides of the top-view surface of the action module 4, a rotating seat 21 is arranged in the middle of the top-view surface of the action module 4, a large torsion spring 22 is wound and installed inside the action module 4 with the rotating seat 21 as the center, one end of the large torsion spring 22 is fixed on the action module 4, and the other end of the large torsion spring 22 is a protruding end 23 located at the edge of the top-view surface of the action module 4.

The semi-rigid connection is that the fixed end 28 is fixed to the rotating seat 21 through a rivet 29 and a small torsion spring 30; wherein the small torsion spring 30 is centered on the rivet 29 and is encircled by the nail column of the rivet 29.The action module 4 may further include an O-ring 34 , a ball spring 33 , a moving contact spring 32 and a limit pin 31 ; wherein the O-ring 34 acts on the rotating seat 21 , the ball spring 33 is used to cushion the ball 20 , and the moving contact spring 32 is connected to the moving contact 24 .

[0078] Combined with Fig. 9 , Attachment Fig.10 , Attachment Fig.11 And attached Fig.12 The switch starting method with a shell anti-restart mechanism is shown as follows: when the switch head rotates 30 degrees clockwise from the state one position to the state two position, and then continues to rotate 30 degrees clockwise to the state three position and stops; under the traction of the switch head, the action module 4 synchronously rotates clockwise from the state one position to the state two position, and then reaches the state three position. When the action module 4 is in the state three position, the ball 20 of the action module 4 rolls into the bead groove 18 at the position corresponding to the gear position, and the upper part of the action module 4 is clamped in the bead groove 18 at the position corresponding to the gear position. After rotating, the moving contact piece under the action module 4 contacts the fixed contact piece of the gear position to complete the switch gear connection. Then, under the action of the restoring force of the large torsion spring 22, the action module 4 rotates counterclockwise to the state four position. When the action module 4 is in the state four position, the protruding end 23 on one side of the action module 4 is directly clamped into the clamping end of the switch shell 3. The positioning block 19, the rotating piece 8 located on the other side of the action module 4 slides into the corner groove 16 of the shell anti-restart mechanism 7, completing the braking mode, that is, stopping the pendulum-like rotation of the action module 4; when the action module 4 completes the above-mentioned rotation process, the rotating piece 8 also rotates clockwise from the state one position through the state two position, and then reaches the state three position in the same pace as the action module 4, and finally returns to the state four position under the counterclockwise traction of the action module 4. When the rotating piece 8 passes the state two position, the free end of the rotating piece 8 slides over the inner ring wall 11 of the switch shell above the shell anti-restart mechanism 7. At this time, the small torsion spring on the fixed end of the rotating piece 8 is twisted to produce a counterclockwise twisting force. When it reaches state three, it is offset by the restoring force of the large torsion spring 22 and reaches state four. It slides into the corner groove 16 of the shell anti-restart mechanism 7 and completes the braking of the action module 4 with the protruding end 23.

[0079] Combined with Fig. 9 And attached Fig.12 As shown, when the switch with housing anti-restart mechanism needs to shift gears again, the switch head rotates back to the state one position, and a new gear selection operation can be restarted. The switch head rotates back to the state one position, and the action module 4 rotates back to the state one position under the traction of the switch head, and the rotating piece 8 slides out of the angle groove 16 synchronously, returns to the state one position, and releases the braking mode of the action module 4.

[0080] In this specific embodiment, state one indicates the starting position state, state two indicates the position above the shell anti-restart mechanism state, state three indicates the starting position state, and state four indicates the braking position state, i.e. the rotating piece returns to the shell anti-restart mechanism position and is stuck in the corner groove.
