Description

Technical Field

[0001] The present invention relates to a lock and its components, and in particular to a lock that can be pivoted to switch operating modes and its mode control module. Background Art

[0002] Currently, many pivot-operated locks, such as those used in gasoline-powered, electric, or hybrid vehicles, feature a housing with multiple recesses corresponding to different operating modes. A knob is manipulated to pivot a disc relative to the housing, allowing a steel ball on the disc to leave its corresponding recess, pass through the plane between adjacent recesses, and reengage in another recess, switching the lock to a different operating mode. This provides feedback to the user confirming a successful mode switch. An embodiment of a lock similar to the aforementioned is disclosed in the applicant's Taiwan Patent No. M555822.

[0003] However, because the pivoting angles between some operating modes are relatively large, the planes between adjacent grooves are relatively wide. If the user does not rotate the knob to the desired angle, the steel ball may stop on the plane after leaving the corresponding groove and fail to actively slide into the target groove. As a result, in practical operation, users may occasionally fail to properly pivot the knob to the desired position, resulting in subsequent operational difficulties or dangers. For example, assuming the aforementioned situation occurs between the ON and OFF operating modes, if the knob is not properly pivoted from ON to OFF, the components connected to the knob may not pivot to the desired position and cannot be locked. Conversely, if the knob is not properly pivoted from OFF to ON, the knob may jump to the ON or OFF position due to vehicle vibrations. However, once it jumps to the OFF position, a sudden power outage may occur during driving, which is dangerous.

[0004] In view of this, the existing locks still need to be improved. Summary of the Invention

[0005] To solve the above problems, the purpose of the present invention is to provide a mode control module for a lock, wherein when its positioning component passes between two grooves with a slightly larger span, the positioning component is not easy to stop and can actively slide into the target groove to guide the lock to actually switch the operating mode.

[0006] Another object of the present invention is to provide a mode control module for a lock that can maintain a stable electrical connection between its electrical conductive connector and the switch panel.

[0007] Another object of the present invention is to provide a mode control module for a lock that can improve assembly and operation convenience.

[0008] Another object of the present invention is to provide a lock having the aforementioned mode control module.

[0009] The present invention defines the Y direction as the axial direction of the latch, where the Y direction represents forward and rearward directions, the X direction represents left and right directions, and the Z direction represents upward and downward directions. Furthermore, throughout the present invention, directional terms such as "inner," "outer," and "lateral," or similar terms, are primarily used with reference to the accompanying drawings. These directional terms and similar terms are intended solely to facilitate description and understanding of the various embodiments of the present invention and are not intended to limit the present invention.

[0010] The quantifiers “a” or “an” used in the components and members described throughout the present invention are merely for convenience and to provide a general meaning of the scope of the present invention. In the present invention, they should be interpreted as including one or at least one, and the concept of a single one also includes the plural case, unless it is obvious that it means otherwise.

[0011] Throughout the present invention, similar terms such as "combination", "assembly" or "assembly" mainly include types in which the components can be separated without damaging each other after connection, or in which the components cannot be separated after connection. Those skilled in the art can choose according to the materials of the components to be connected or the assembly requirements.

[0012] The mode control module of the lock of the present invention comprises: a rotating shaft; a mounting seat having a sleeve, a sleeve bottom surface facing the opening of the sleeve, the mounting seat having a plurality of grooves recessed from the sleeve bottom surface, the plurality of grooves being arranged around a through hole, the groove bottom surface of each groove having a center line extending through the center of the through hole, wherein the angle between the center lines of two adjacent grooves is greater than 20 degrees and less than 90 degrees, an anti-parking structure is located between the two adjacent grooves, the anti-parking structure having a ridge; and a linkage disk, In the sleeve, the linkage disk has a disk body and at least one positioning component, the rotating shaft passes through the through hole and penetrates into a driving hole of the disk body, and the positioning component can be elastically and telescopically arranged on the disk body; wherein, when the rotating shaft links the linkage disk to pivot, the positioning component disengages from the inside of one of the two adjacent grooves along an arc path, passes through the anti-stopping structure and then snaps into the inside of the other of the two adjacent grooves, wherein when the positioning component abuts the ridge of the anti-stopping structure, the positioning component is compressed and elastically retracted into the disk body.

[0013] The lock of the present invention comprises: a body; a mode control module of the lock as described above, wherein the rotating shaft passes through the body and the mounting seat is combined with the body; a knob connected to the rotating shaft; and a switch plate adjacent to the linkage plate, wherein the knob links the linkage plate via the rotating shaft to pivot relative to the switch plate.

[0014] Therefore, the lock and its mode control module of the present invention can effectively prevent the positioning component from stopping between two grooves with larger pivot switching angles with the help of the guidance of the anti-stop structure, so that the linkage plate can accurately pivot to the expected angle, thereby accurately switching the operating mode and avoiding subsequent operational difficulties or dangers, thereby improving operational convenience and safety.

[0015] The disc body may include a mounting post, and the positioning assembly may include an elastic member and a latch member located in a countersunk hole of the mounting post. The elastic member may push the latch member to partially protrude from the mounting post. Each groove may include two inclined groove walls connecting two sides of the groove bottom surface, and the latch member may abut the two inclined groove walls of one of the grooves. In this way, the latch member can have a telescopic function with a simple structure, thereby improving manufacturing and assembly convenience.

[0016] The latching member may be a spherical body, and one end of the mounting post may have a gripping portion. The gripping portion may have a minimum diameter smaller than the diameter of the spherical body, and the gripping portion may be located where the anti-parking structure does not pass. This not only facilitates the manufacture and assembly of the positioning assembly, but also prevents the gripping portion from interfering with the anti-parking structure during the pivoting of the linkage plate, thereby improving manufacturing, assembly, and operational convenience.

[0017] The latching member may be a sleeve, into which a portion of the elastic member may be inserted, and the outer edge of the latching member may be hemispherical and protrude from the mounting post. This simplifies the structure of the disc body, effectively prevents the latching member from being dislodged during extension and retraction, and prevents interference with the anti-stop structure during pivoting of the linkage disc, thereby improving manufacturing, assembly, and operational convenience.

[0018] The ridge of the anti-staying structure does not need to protrude beyond the bottom surface of the tube, thus facilitating processing and molding.

[0019] The anti-staying structure may protrude from the bottom surface of the cylinder, and the ridge of the anti-staying structure may be planar, with a width less than half the diameter of the latching member. This prevents the latching member from resting on the ridge, allowing the anti-staying structure to effectively guide the linkage disk to accurately pivot to switch operating modes.

[0020] The two adjacent slanted groove walls of the two adjacent grooves may each have a tangent passing through the outermost convex portion. The two tangents may have an intersection. The intersection has a first height from the bottom surface of the cylinder, and the ridge has a second height from the bottom surface of the cylinder. The second height may be less than or equal to the first height. This can avoid increasing the resistance to pivoting the knob and affecting operability, thereby improving operational smoothness.

[0021] The second height can be greater than or equal to one third of the first height. In this way, the anti-stop structure can effectively prevent the latch from stopping between the two grooves to accurately switch the operating mode, thereby improving operational convenience and safety.

[0022] The anti-staying structure may protrude from the bottom surface of the cylinder and may include two guide sections located on either side of the ridge. The two guide sections may respectively connect to an oblique groove wall of two adjacent grooves. The longitudinal spacing between the guide sections and the groove bottom surfaces of the adjacent grooves may increase continuously toward the ridge. Thus, the guide sections may form an arc or an inclined surface, allowing the latch to pass through the anti-staying structure more smoothly, resulting in a better operating feel.

[0023] The anti-stall structure can include two guide sections, one on each side of the ridge, with the longitudinal spacing between the guide sections and the bottom surface of the adjacent groove increasing discontinuously toward the ridge. This creates a climbing structure with alternating slopes and flat surfaces, reducing the longitudinal spacing between the ridge and the bottom surface of the adjacent groove. This significantly reduces mold costs and improves assembly convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] To make the above and other objects, features and advantages of the present invention more clearly understood, preferred embodiments of the present invention are listed below and described in detail with reference to the accompanying drawings.

[0082] Please refer to Figure 1 As shown, it is a first embodiment of the lock of the present invention, comprising a body 1, a rotating shaft 2, a knob 3, a mounting base 4, a linkage plate 5 and a switch plate 6. The mounting base 4 is coupled to the body 1, the linkage plate 5 is located in the mounting base 4, and the switch plate 6 is adjacent to the linkage plate 5; the rotating shaft 2 is connected to the knob 3 and penetrates the mounting base 4, so that when the knob 3 is rotated, the linkage plate 5 is linked to pivot relative to the switch plate 6 via the rotating shaft 2.

[0083] The rotating shaft 2, the mounting base 4, and the linkage plate 5 can constitute a mode control module M. It is worth noting that the mode control module M of the present invention can be applied to various pivot-operated locks, particularly master locks for vehicles such as gasoline-powered vehicles, electric vehicles, and hybrid vehicles. The following description uses an induction-based master lock as an example, which is used in conjunction with a keyless start system to replace a key-based master lock controlled by a physical key, but the application is not limited to this.

[0084] The shape of the main body 1 can be adjusted based on the space constraints of the installation location or the needs of assembling and positioning other components, and is not limited to the shape shown in the drawings of this embodiment. In this embodiment, the bottom end of the main body 1 can be open and have a chamber 11. A locking bolt 12 is disposed in a bolt hole 13 of the main body 1 and is movable along the Y direction. The bolt hole 13 can communicate with the chamber 11.

[0085] When fully assembled, the shaft 2 extends through the body 1 along the Z direction, with the lower end of the shaft 2 positioned within the chamber 11 and the upper end of the shaft 2 extending beyond the body 1 to connect to the knob 3. After the lock is assembled to the vehicle body, the knob 3 can be exposed outside the vehicle body, allowing the user to grasp and pivot the knob. Pivoting the knob 3 switches between different operating modes and also activates various components within the body 1 to control actions such as turning the power on (ON), turning the power off (OFF), or opening a storage compartment or energy box, depending on the operating mode. However, these mechanisms and controls are not the focus of this invention and will not be described in detail here.

[0086] Please refer to Figure 1 、 Figure 2 As shown, the mounting base 4 has a sleeve 4a for accommodating the linkage plate 5. The sleeve 4a can be connected to the outer surface of a box body 4b. The mounting base 4 has a through hole 41 that connects the sleeve 4a with the interior of the box body 4b. The mounting base 4 has a bottom surface 42 that faces the opening of the sleeve 4a. The mounting base 4 also has a plurality of grooves 43 that are recessed from the bottom surface 42 toward the box body 4b, and the plurality of grooves 43 are arranged around the through hole 41. Each groove 43 has a bottom surface 431 adjacent to the box body 4b. Each groove 43 can have two inclined groove walls 432 connecting the two sides of the bottom surface 431, so that each groove 43 is wider at the opening and narrower at the bottom surface 431.

[0087] Pivoting the knob 3 activates the interlocking plate 5 via the shaft 2. After pivoting a predetermined angle, the interlocking plate 5 engages in one of the grooves 43. Further pivoting releases the groove 43 and engages in the other groove 43, switching operating modes. To enhance the stability of the aforementioned engaging action, this embodiment utilizes an even number of grooves 43. In each operating mode, the interlocking plate 5 can simultaneously engage in two spaced grooves 43. Preferably, the two grooves 43 corresponding to the same mode are aligned 180 degrees apart, centered around the through hole 41.

[0088] Please refer to Figure 4 As shown, on the radial plane of the sleeve 4a, the bottom surface 431 of each groove 43 has a centerline L1 extending through the center of the through-hole 41. The centerlines L1 of any two adjacent grooves 43 form an included angle θ. When the included angle θ is greater than 20 degrees and less than 90 degrees, an anti-stop structure 44 is located between the two adjacent grooves 43 to prevent the interlocking plate 5 from stopping at the portion of the sleeve bottom surface 42 between the two adjacent grooves 43 during pivoting. The anti-stop structure 44 guides the interlocking plate 5 into the desired groove 43 to accurately switch operating modes.

[0089] Please refer to Figure 1 、 Figure 3 As shown, the linkage disk 5 is located within the sleeve 4a. The linkage disk 5 comprises a disk body 51 with a driving hole 52 at its center. The driving hole 52 has a hole shape that matches the non-circular cross-section of the lower end of the rotating shaft 2. The rotating shaft 2 passes through the through hole 41 and into the driving hole 52, allowing the linkage disk 5 to pivot in conjunction with the rotating shaft 2. The linkage disk 5 may also have at least one positioning assembly 53 and at least one electrical connector 54, respectively located at opposite ends of the disk body 51 in the axial direction.

[0090] The positioning member 53 is provided on the disc body 51 and can be elastically extended relative to the axial direction of the disc body 51. When the positioning member 53 is in an extended state, it is locked in one of the aforementioned grooves 43 (such as Figure 5 ). Similarly, to enhance the stability of the aforementioned latching action, this embodiment can optionally include two positioning assemblies 53, with the two positioning assemblies 53 positioned 180 degrees apart and centered around the driving hole 52. More specifically, the disk body 51 of this embodiment can include multiple mounting posts 511, which can be arranged at equal angles around the driving hole 52. For example, the number of mounting posts 511 can be four, but is not limited thereto. Two of the mounting posts 511 can be used to mount the two positioning assemblies 53, while the other two mounting posts 511 can each be used to mount one of the aforementioned electrical connectors 54.

[0091] Please refer to Figure 3 、 Figure 5 As shown, the positioning assembly 53 may include an elastic member 531 and a latching member 532. The elastic member 531 and the latching member 532 are located together in a countersunk hole 512 of the mounting post 511. With the push of the elastic member 531, the outer edge of the latching member 532 can protrude from the mounting post 511, so as to be latched and positioned in one of the aforementioned grooves 43. In addition, when the latching member 532 is a spherical object (such as a steel ball), one end of the mounting post 511 may have a gripping portion 513. The minimum diameter of the gripping portion 513 can be smaller than the diameter D1 of the spherical object, so as to limit the volume of the latching member 532 to at least more than half of the volume within the mounting post 511, thereby preventing the latching member 532 from falling out during the extension and retraction process. To prevent the gripping portion 513 from interfering with the anti-parking structure 44 during the pivoting of the linkage plate 5 , it is preferred that the gripping portion 513 be located where the anti-parking structure 44 will not pass, such as near the outside of the mounting post 511 .

[0092] Please refer to Figure 1 、 Figure 3 As shown, the electrical connector 54 can be, for example, a copper sheet with good conductivity. The electrical connector 54 has a plurality of contacts 541 protruding from the bottom surface, and the plurality of contacts 541 are spaced apart from each other. The electrical connector 54 can be fixed at a predetermined position on the mounting post 511, with the plurality of contacts 541 contacting the switch panel 6. Alternatively, the electrical connector 54 can preferably be slightly axially displaced relative to the mounting post 511, and an elastic member 55 is disposed in the counterbore 512 of the mounting post 511 to push the electrical connector 54 downward, so that the electrical connector 54 can maintain contact with the switch panel 6 with the plurality of contacts 541, thereby preventing the plurality of contacts 541 from failing to accurately contact the switch panel 6 due to manufacturing tolerances of the various components.

[0093] Please refer to Figure 4 As shown, when the disc 51 pivots, the latch 532 of the positioning assembly 53 will move along an arc path on the radial plane of the sleeve 4a, and the anti-parking structure 44 is located on the arc path. Figure 5 、 Figure 7As shown, in this embodiment, the anti-staying structure 44 may protrude from the bottom surface 42 of the cylinder. The anti-staying structure 44 includes a ridge 441 that is longitudinally farthest from the bottom surface 431 of the adjacent groove 43. Two guide sections 442 are located on either side of the ridge 441. The two guide sections 442 are respectively closer to the oblique groove walls 432 of the two adjacent grooves 43 than the ridge 441, and preferably, they are connected to the oblique groove walls 432 of the two adjacent grooves 43. The longitudinal distance D2 between the ridge 441 and the bottom surface 431 of the adjacent groove 43 may be greater than the longitudinal distance D3 between the guide section 442 and the bottom surface 431 of the adjacent groove 43. For example, but not limitation, the longitudinal distance D3 between the guide section 442 and the bottom surface 431 of the adjacent groove 43 may increase toward the ridge 441, and may continuously increase to form a curved surface or an inclined surface, with a convex curved surface being preferred.

[0094] Please refer to Figure 1 、 Figure 5 As shown, in the lock of this embodiment, two adjacent grooves 43 that are farther apart can correspond to the OFF and ON operating modes respectively. For the convenience of explanation, the groove 43 corresponding to the OFF mode is referred to as the "first groove 43a", and the groove 43 corresponding to the ON mode is referred to as the "second groove 43b". Assuming that the positioning component 53 of the linkage plate 5 is originally locked in the first groove 43a, that is, the locking member 532 abuts against the two inclined groove walls 432 of the first groove 43a, then during the clockwise pivoting of the knob 3, the shaft 2 can link the linkage plate 5 to pivot, so that the locking member 532 moves along the left side of the first groove 43a (according to the rotation direction of the knob 3). Figure 5 The inclined groove wall 432 (in terms of FIG. 4 ) moves toward the ridge 441 of the anti-parking structure 44 , and in the process of climbing along the guide section 442 , pushes the latching member 532 to gradually elastically retract into the mounting post 511 .

[0095] Please refer to Figure 1 、 Figure 6As shown, when the latch 532 climbs to the ridge 441 of the anti-stop structure 44, the contact area between the latch 532 and the ridge 441 is very small, making it difficult for the latch 532 to stop on the ridge 441; coupled with the force of pivoting the knob 3, the latch 532 can slide along the guide section 442 adjacent to the second groove 43b toward the second groove 43b, and the latch 532 can gradually elastically extend outward from the mounting post 511 to maintain contact with the guide section 442, thereby being pressed against the reaction force of the guide section 442 by the latch 532, pushing the latch 532 toward the second groove 43b, so that the latch 532 can be accurately guided and latched into the second groove 43b to convert the operating mode from OFF mode to ON mode. On the other hand, the electrical conductive member 54 of the linkage disk 5 can also be electrically connected to a plurality of designated pins 61 on the switch disk 6 .

[0096] If the ridge 441 of the anti-staying structure 44 is too high, the resistance to pivoting the knob 3 will increase, affecting operability; conversely, if the ridge 441 of the anti-staying structure 44 is too low, the effect of preventing the latch 532 from staying between the two grooves 43b will be reduced. Therefore, in order to more smoothly and effectively guide the latch 532 from the first groove 43a to the second groove 43b (or vice versa) by the anti-staying structure 44, please refer to Figure 6 、 Figure 7 As shown, the two adjacent chute walls 432 of the first groove 43a and the second groove 43b each have a tangent line L2 and L3 passing through the outermost convex portion. These two tangent lines L2 and L3 intersect at a point P. The intersection P has a first height H1 from the cylinder bottom surface 42. The ridge 441 has a second height H2 from the cylinder bottom surface 42. This second height H2 is less than or equal to the first height H1, and preferably greater than or equal to one-third of the first height H1. In this embodiment, the chute wall 432 is convexly curved, so the two tangent lines L2 and L3 pass through the outermost convex portion. In embodiments where the chute wall 432 is an inclined plane, the two tangent lines L2 and L3 extend along the chute wall 432.

[0097] Please refer to Figure 8 As shown, it is a second embodiment of the mode control module M of the present invention. In this embodiment, the anti-stopping structure 44 can have a longer protrusion range, for example, the protrusion range of the anti-stopping structure 44 is made the same as the recessed range of the groove 43, so that the anti-stopping structure 44 forms a long protrusion, which is different from the first embodiment in which a protrusion is formed on the bottom surface 42 of the cylinder, but both can achieve the effect of guiding the latching member 532 to smoothly switch the latching groove 43 as mentioned above.

[0098] In addition, please refer to Figure 8 、 Figure 9As shown, this embodiment also discloses another type of latching member 532; that is, the latching member 532 can be selected as a sleeve, so that the elastic member 531 can partially penetrate the latching member 532, and the outer edge of the latching member 532 is hemispherical so as to protrude from the mounting post 511. Since the latching member 532 has sufficient volume to be accommodated in the mounting post 511, when the latching member 532 is in the sleeve type, the aforementioned gripping portion 513 (marked on the end) of the mounting post 511 does not need to be provided. Figure 3 ), it can also prevent the latching member 532 from coming out during the extension and retraction process, and will not interfere with the anti-parking structure 44 during the pivoting process of the linkage plate 5.

[0099] Please refer to Figure 8 、 Figure 10 As shown, in the mode control module M of this embodiment, when the latching member 532 abuts against the two inclined groove walls 432 of the first groove 43a, the pivoting shaft 2 can link the linkage plate 5 to pivot synchronously, so that the latching member 532 is elastically retracted into the mounting post 511 during the process of climbing along the anti-parking structure 44, and is elastically extended outward from the mounting post 511 during the process of descending along the anti-parking structure 44; and after passing through the ridge 441 of the anti-parking structure 44, the latching member 532 can be guided to accurately switch the operating mode.

[0100] Please refer to Figure 11 As shown, in other embodiments in which the latch member 532 is in the form of a sleeve, the ridge 441 of the anti-stopping structure 44 may not protrude beyond the bottom surface 42 of the cylinder; for example, but not limitation, the figure of this embodiment shows that the ridge 441 passes through the extension surface of the bottom surface 42 of the cylinder, and the two guide sections 442 of the anti-stopping structure 44 are lower than the bottom surface 42 of the cylinder and are respectively connected to the inclined groove walls 432 of the first groove 43a and the second groove 43b. When the latching member 532 is positioned opposite to the first groove 43a, it can firmly abut the two inclined groove walls 432 of the first groove 43a; when the linkage plate 5 pivots, the latching member 532 can elastically expand and contract relative to the mounting post 511, and after passing through the ridge 441 of the anti-stopping structure 44, the latching member 532 is guided by the guide section 442 of the anti-stopping structure 44 to slide toward the second groove 43b, and the latching member 532 can firmly abut the two inclined groove walls 432 of the second groove 43b.

[0101] Please refer to Figure 12 As shown, in another embodiment, the ridge 441 of the anti-stopping structure 44 can also be planar, so that the longitudinal distance D2 from the entire ridge 441 to the groove bottom surface 431 of the adjacent groove 43 is equal, and the width W of the planar ridge 441 can be less than half of the diameter D1 of the latch 532.

[0102] Please refer to Figure 13 As shown, in another embodiment, the longitudinal distance D3 from the guide section 442 of the anti-stopping structure 44 to the groove bottom surface 431 of the adjacent groove 43 can be discontinuously increased toward the ridge 441 to form a climbing structure with alternating inclined surfaces and planes; in this way, compared with the aforementioned embodiment in which the guide section 442 to the ridge 441 is a continuous inclined surface or arc surface, the longitudinal distance D2 from the ridge 441 to the groove bottom surface 431 of the adjacent groove 43 in this embodiment can be reduced.

[0103] In summary, the lock and its mode control module of the present invention can effectively prevent the positioning component from stopping between two grooves with larger pivot switching angles with the help of the guidance of the anti-stop structure, so that the linkage disk can accurately pivot to the expected angle, thereby effectively switching the operating mode and avoiding subsequent operational difficulties or dangers, thereby improving operational convenience and safety.
