Description

Technical Field

[0001] This utility model relates to the field of locomotive ignition lock technology, specifically to a waterproof ignition lock. Background Technology

[0002] Existing ignition locks mainly drain water through a drain hole. Water flows through the lock cylinder, then through the lock cover, with some entering the rotor and the rest flowing along the inner wall of the lock body or the outer side of the rotor to the drain hole, where it is discharged. Because the drain hole is close to the ignition lock contacts, it can easily cause a short circuit when draining water, and it can also easily corrode the contacts, leading to poor contact.

[0003] Chinese utility model patent publication number "CN208521840U" discloses a waterproof structure for an ignition lock, including a lock body. The lock body has a lock cylinder placement cavity and a rotor placement cavity. The lock cylinder is placed in the lock cylinder placement cavity. A first through hole is provided on the partition between the lock cylinder placement cavity and the rotor placement cavity. A linkage shaft is embedded in the first through hole. The top end of the linkage shaft is connected to the lock cylinder. An annular waterproof boss is provided on the bottom surface of the partition. A rotor is placed in the rotor placement cavity. The rotor has a contact piece. A shaft hole is provided at the center of the top surface of the rotor. The bottom end of the linkage shaft is embedded in the shaft hole. An annular water groove is provided on the top surface of the rotor around the shaft hole. The annular waterproof boss is embedded in the annular water groove. A hollow shaft is provided at the center of the bottom surface of the rotor. The hollow shaft is connected to the annular water groove. A second through hole is opened at the bottom end of the rotor placement cavity. The free end of the hollow shaft is embedded in the second through hole.

[0004] However, a gap still exists between the rotor and the rotor placement cavity in the aforementioned waterproof ignition lock structure. During vehicle operation, water in the annular water tank may pass through the gap between the rotor and the rotor placement cavity due to vibration, and then converge on the contact plate through the inner wall of the lock body or the outer circumference of the rotor. There is still a risk of short circuit or poor contact in the ignition lock.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof ignition lock that can isolate the conductive rotor and contact plates inside the ignition lock from rainwater, thereby preventing rust on the conductive parts and resulting in poor ignition connection of the ignition lock, thus solving the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waterproof ignition lock, including a lock shell, a lock cylinder and a rotating shaft rotatably disposed inside the lock shell, a stop seat detachably connected to the lock shell, the stop seat having a shaft hole for the rotating shaft to pass through, the stop seat including a mounting cylinder, a rotor disposed inside the mounting cylinder, a conductive sheet linked to the rotor, a cover plate disposed on the side of the mounting cylinder opposite to the lock cylinder, the cover plate having a contact piece and a wiring terminal, characterized in that: a first connecting post is disposed at the end of the rotor near the shaft hole, the first connecting post having a connection port for the rotating shaft to pass through, a second connecting post is disposed at the end of the rotor opposite to the first connecting post, the second connecting post having a drainage channel along the axial direction, the drainage channel communicating with the connection port, a drainage port is disposed in the middle of the cover plate, the end of the second connecting post passing through the drainage port, and an annular waterproof rim extending from the outer circumference of the end of the rotor near the cover plate.

[0008] By adopting the above technical solution: rainwater permeates through the lock cylinder to the rotor inside the mounting cylinder. When the amount of rainwater flowing in is large, the rainwater enters the mounting cylinder through the shaft hole. The rotating shaft guides the rainwater into the connection port, and then through the drainage channel of the second connecting column and through the drainage port of the cover plate to be discharged outside the mounting cylinder. When there is a lot of rainwater, the drainage efficiency of the connection port is insufficient, and some rainwater will overflow to the outer surface of the rotor. Since the waterproof edge is in contact with the end face of the cover plate when the rotor and the cover plate are installed in the mounting cylinder, the rainwater is isolated on the outer circumference of the waterproof edge and seeps out from the connection between the cover plate and the mounting cylinder, effectively preventing rainwater from corroding the conductive parts and causing the ignition lock to short circuit.

[0009] The aforementioned waterproof ignition lock can be further configured as follows: a positioning protrusion is provided on the end face of the mounting cylinder near the rotor, the rotor is provided with a connecting cylinder that cooperates with the positioning protrusion, the first connecting post is located inside the connecting cylinder, a liquid collection cavity is formed between the inner wall of the connecting cylinder and the first connecting post, the first connecting post is provided with a liquid inlet notch that connects the liquid collection cavity and the connecting port, and a liquid inlet slope is provided at the bottom of the liquid inlet notch.

[0010] By adopting the above technical solution: the connecting cylinder is located on the outer ring of the first connecting column, so that the inner wall of the connecting cylinder and the outer wall of the first connecting column form an annular liquid collection cavity. When the amount of infiltrated water is relatively large, the liquid collection cavity can concentrate the water and prevent rainwater from splashing out. In addition, the connecting cylinder is located on the inner ring of the positioning convex ring, which can seal the edge of the liquid collection cavity while installing and positioning the rotor, reducing the risk of rainwater seeping out of the liquid collection cavity. Furthermore, the rainwater in the liquid collection cavity will flow into the connection port through the liquid inlet notch on the side wall of the first connecting column, and then flow out through the drainage hole and drainage groove. The liquid inlet slope can guide the water in the liquid collection cavity, so that the water can flow smoothly into the connection port and improve the drainage efficiency.

[0011] The aforementioned waterproof ignition lock can be further configured such that: a positioning step that matches the waterproof edging is provided on the end face of the cover plate near the rotor.

[0012] By adopting the above technical solution, when the waterproof edge contacts the cover plate, its end edge can fit with the gap of the installation step, which can prevent water from seeping through the gap between the waterproof edge and the cover plate. At the same time, the end of the wiring terminal is raised, which further improves the protection of the guide plate and the contact plate.

[0013] The aforementioned waterproof ignition lock can be further configured as follows: the side wall of the mounting cylinder is provided with a number of first mounting slots and a number of second mounting slots; the outer periphery of the cover plate is provided with a first mounting block that is linked to the first mounting slots and a second mounting block that is linked to the second mounting slots; the edge of the end face of the cover plate is provided with an arc-shaped drainage surface; and the edge of the cover plate is also provided with a water leakage notch.

[0014] By adopting the above technical solution: during the installation of the cover plate, since the second mounting block is slightly longer than the first mounting block, the second mounting block needs to be inserted into the second mounting slot first, and then the first mounting block is pressed into the first mounting slot. The mounting cylinder has a certain elastic deformation capability, and the first mounting block can be stably inserted into the first mounting slot, ensuring the stability of the relative position between the cover plate and the mounting cylinder, improving the stability of the contact between the rotor and the end face of the cover plate, and after the cover plate is installed and fixed, there is a gap between the lower end face of the arc-shaped drainage surface and the side of the mounting cylinder, and between the upper end face and the first and second slots. Rainwater located outside the rotor can be discharged through the gaps and can also be discharged through the leakage gaps, preventing rainwater from staying in the space between the outer circumference of the waterproof enclosure and the inner wall of the mounting cylinder.

[0015] The aforementioned waterproof ignition lock can be further configured as follows: a cover sleeve is fitted on the outer circumference of the mounting cylinder, the cover sleeve has a wire through hole, a third mounting slot is opened on the side wall of the cover sleeve, the third mounting slot cooperates with the second mounting block, the mounting cylinder is inserted into the cover sleeve to cause the end of the second mounting block to engage with the third mounting slot, a guide groove is opened on the inner wall of the cover sleeve, the bottom of the guide groove is inclined, one end of the guide groove is located at the edge of the opening of the cover sleeve, and the other end is located on the side of the second mounting slot.

[0016] By adopting the above technical solution: after the rotor and cover plate are installed inside the mounting cylinder, the wiring of the terminal block passes through the wire hole of the cover cylinder. At the same time, the cover cylinder is sleeved on the outside of the mounting cylinder, which can shield the first mounting slot and the second mounting slot, preventing external rainwater from seeping into the lock housing from the connection between the mounting cylinder and the cover plate, thus improving the waterproof performance of the ignition lock. When installing the cover cylinder, the inclined surface of the guide groove on the inner wall of the cover cylinder will contact the end of the protruding second mounting block. During the axial pressing of the cover cylinder, the inclined surface of the guide groove guides the movement direction of the second mounting block relative to the cover cylinder, accurately aligning the end of the second mounting block and locking it into the third mounting slot of the cover cylinder, realizing the quick and stable locking of the cover cylinder and the gear seat, and ensuring the precise fixation of the relative position between the cover cylinder, the gear seat, and the cover plate.

[0017] The aforementioned waterproof ignition lock can be further configured such that: the inner wall of the cover cylinder is provided with a number of positioning blocks, and the mounting cylinder is provided with a number of positioning slots corresponding to the positioning blocks, so that the positioning blocks can be engaged in the positioning slots to prevent the cover cylinder from rotating circumferentially.

[0018] By adopting the above technical solution: the positioning block on the inner wall of the cover cylinder cooperates with the positioning groove on the outer periphery of the mounting cylinder. When the second mounting block is engaged in the third mounting slot, the positioning block is simultaneously embedded in the corresponding positioning groove. This achieves a detachable connection between the cover cylinder and the mounting cylinder while limiting the position of the cover cylinder, preventing the cover cylinder from rotating or shifting circumferentially relative to the stop seat. This ensures the stability of the cover cylinder installation and avoids accidental loosening caused by vibration or operating force.

[0019] The aforementioned waterproof ignition lock can be further configured as follows: the inner wall of the lock shell is provided with an integrally formed positioning boss, the lock cylinder is provided with a first positioning block, the first positioning block can contact the end face of the positioning boss, the connection between the positioning boss and the lock shell is provided with a first limiting block and a second limiting block, a sliding groove is formed between the first limiting block and the second limiting block, a positioning plate is provided at one end of the rotating shaft near the lock cylinder, the positioning plate is provided with a second positioning block, the end of the second positioning block can contact the bottom of the sliding groove, and the second positioning block slides with the sliding groove.

[0020] By adopting the above technical solution: during the assembly of the ignition lock, the lock cylinder and the rotating shaft are assembled first, and then the lock cylinder and the device are inserted into the lock shell, so that the first positioning block on the lock cylinder contacts the end face of the positioning boss, limiting the lock cylinder and preventing it from being pulled out of the lock shell axially. The second positioning block on the positioning plate falls into the sliding groove between the first and second limiting blocks. The second positioning block is limited by the first and second limiting blocks, and the lock cylinder and the rotating shaft cannot rotate circumferentially. After the corresponding key is inserted, the blade on the lock cylinder is reset, which can push the lock cylinder to move axially, drive the rotating shaft axis to move, and cause the second positioning block to be misaligned relative to the first and second limiting blocks, thereby realizing the circumferential unlocking of the lock cylinder and enabling the lock cylinder to rotate circumferentially. This structure only needs to be aligned and installed during assembly, and after installation, it will not affect the unlocking and rotation of the lock cylinder during actual use. In order to adapt to the unlocking function of each position of the lock cylinder, the sliding groove can be set to an angle adapted to the position to achieve the positioning function.

[0021] The aforementioned waterproof ignition lock can be further configured as follows: several sets of ball grooves are opened on the outer circumference of the rotor, and balls and ball springs are provided in the ball grooves. One end of the ball spring abuts against the ball and the other end abuts against the inner wall of the ball groove. Several arc-shaped stop blocks are arranged at intervals in the mounting cylinder, and a stop groove is formed between each two adjacent stop blocks. The rotation of the rotor causes the balls to be engaged or disengaged from the stop groove.

[0022] By adopting the above technical solution: under the elastic force of the ball spring, the ball is always in contact with the side wall of the gear position seat. When the rotor rotates to the point where the ball contacts the gear block, the ball is squeezed back into the ball groove. When the rotor continues to rotate until the ball is aligned with the gear groove, the ball is quickly ejected and locked into the gear groove under the action of the spring, so as to realize the precise positioning and holding of the rotor in the preset gear, and provide clear tactile feedback, ensuring the reliability and stability of gear switching.

[0023] The aforementioned waterproof ignition lock can be further configured such that: a ball retainer is provided on the circumferential surface of the open end of the ball groove of the rotor, the ball retainer is provided with an arc-shaped limiting step, the limiting step is adapted to the outer contour of the ball, and the ball retainer is used to hold the ball in place so that the ball is always located in the ball groove.

[0024] By adopting the above technical solution: the ball retainer is set at the opening end of the ball groove, and the arc-shaped limiting step closely fits the outer contour of the ball, which can block the ball and prevent the ball from falling out of the ball groove. During the rotation of the rotor and the interaction between the ball and the gear block and gear groove, the ball retainer can reliably maintain the correct position of the ball in the ball groove, prevent the ball from axially shifting or accidentally falling off due to vibration or centrifugal force, and ensure the reliability and stability of gear switching.

[0025] The aforementioned waterproof ignition lock can be further configured such that: the conductive sheet has a contact groove protruding to one side of the cover plate, the rotor has a spring groove along the axial direction, a contact spring passes through the spring groove, one end of the contact spring abuts against the inner wall of the spring groove, and the other end abuts against the contact groove.

[0026] By adopting the above technical solution: when the rotor and the cover plate are installed in the mounting cylinder, the contact spring can continuously apply elastic force to the conductive sheet, so that the contact groove of the conductive sheet is pressed against the cover plate, ensuring that the protruding part of the contact groove can form a stable and reliable electrical contact with the contact sheet and the end face of the wiring terminal, avoiding poor contact due to vibration or gaps that could affect ignition performance.

[0027] The beneficial effects of this utility model are as follows: By connecting the connection port above the rotor for connecting the rotating shaft to the drainage groove of the second connecting column, water flowing to the top of the rotor can flow from the connection port through the drainage hole into the drainage groove of the second connecting column, and then be discharged through the drainage port of the cover plate. Since the end of the second connecting column passes through the drainage port, the water discharged from the drainage groove will not contact the cover plate. That is, the water flows directly from the top of the rotor through the connection port, drainage hole, and drainage groove and flows directly out of the cover plate on the side opposite to the rotor. Furthermore, when a large amount of water flows in and rainwater overflows onto the outer circumference of the rotor, the waterproof rim protects the rotor. Surrounded by the conductive sheets, contact sheets, and terminal faces on the cover plate, rainwater will not seep into the interior of the waterproof enclosure and will flow out from the gap between the drainage surface and the mounting cylinder and the drainage opening. Compared with the existing technology that only sets a hollow rotating shaft in the middle of the rotor, it can isolate the rainwater overflowing to the outer circumference of the rotor, avoiding corrosion and short circuit problems caused by rainwater contacting the contact sheets or terminal faces. At the same time, the cover cylinder set on the side of the gear position seat where the rotor switch is installed can protect the rotor switch, prevent external rainwater from seeping in from the bottom of the ignition lock, and extend the service life of the ignition lock.

[0035] like Figures 5 to 10 The rotor 5 shown has a first connecting post 52 near the shaft hole 41. The first connecting post 52 has a connection port 521, and the rotating shaft 3 passes through the connection port 521.

The rotor 5 has a connecting cylinder 55, which cooperates with the positioning convex ring 43. The first connecting post 52 is located inside the connecting cylinder 55. A liquid collection cavity 551 is formed between the inner wall of the connecting cylinder 55 and the first connecting post 52. The first connecting post 52 has a liquid inlet notch 522 that communicates the liquid collection cavity 551 and the connection port 521.

[0036] The rotor 5 has several sets of ball grooves 56 on its outer circumferential surface. Balls 561 and ball springs 562 are provided in the ball grooves 56. One end of the ball spring 562 abuts against the ball 561 and the other end abuts against the inner wall of the ball groove 56. Several arc-shaped stop blocks 46 are arranged at intervals in the mounting cylinder 42. A stop groove 47 is formed between each two adjacent stop blocks 46. The rotation of the rotor 5 causes the ball 561 to be engaged or disengaged from the stop groove 47. The rotor 5 has a ball retainer block 563 on the circumferential surface of the opening end of the ball groove 56. The ball retainer block 563 has an arc-shaped limiting step 564. The limiting step 564 is adapted to the outer contour of the ball 561. The ball retainer block 563 is used to hold the ball 561 so that the ball 561 is always located in the ball groove 56.

[0037] The conductive sheet 51 is provided with a contact groove 511 protruding to one side of the cover plate 6. The rotor 5 is provided with a spring groove 57 along the axial direction. A contact spring 571 passes through the spring groove 57. One end of the contact spring 571 abuts against the inner wall of the spring groove 57, and the other end abuts against the contact groove 511.

[0038] A drain outlet 63 is provided in the middle of the cover plate 6. The second connecting column 53 is inserted into the drain outlet 63 and its end protrudes from the cover plate 6. A positioning step 64 that cooperates with the waterproof edge 54 is provided on the end face of the cover plate 6 near the rotor 5. A first mounting block 65 that is linked with the first mounting slot 44 and a second mounting block 66 that is linked with the second mounting slot 45 are provided on the outer periphery of the cover plate 6.

[0039] like Figure 11 The cover cylinder 7 shown has a wire-passing port 71, and a third mounting slot 72 is opened on the side wall of the cover cylinder 7. The third mounting slot 72 cooperates with the second mounting block 66. The mounting cylinder 42 is inserted into the cover cylinder 7, causing the end of the second mounting block 66 to be engaged in the third mounting slot 72. A guide groove 73 is opened on the inner wall of the cover cylinder 7. The bottom of the guide groove 73 is inclined. One end of the guide groove 73 is located at the edge of the opening of the cover cylinder 7, and the other end is located on the side of the second mounting slot 45. Several positioning blocks 74 are provided on the inner wall of the cover cylinder 7. The positioning blocks 74 can be engaged in the positioning slots 48 to prevent the cover cylinder 7 from rotating circumferentially.

[0040] The working principle of this embodiment is as follows: Rainwater flows into the lock housing 1 through the gap between the lock cylinder 2 and the lock housing 1. Some of the rainwater is discharged directly through the drain hole 17 on the side of the lock housing 1. The remaining rainwater flows through the lock cylinder 2 and the pivot 3 to the pivot hole 41 in the stop seat 4, and then flows into the mounting cylinder 42 through the pivot hole 41. Since the end of the pivot 3 passes through the connection port 521 of the first connecting post 52, the pivot 3 guides the rainwater to the first connecting post 52. Some of the rainwater flows directly from the connection port 521 through the drainage channel 531 and is discharged from the second connecting post 53 into the cover cylinder 7. The remaining rainwater first flows into the liquid collection chamber 551, and then flows into the connection port 521 through the liquid inlet notch 522 and the liquid inlet slope 523 on the side of the connection port 521. Then it is discharged from the second connecting post 53 into the cover cylinder 7 through the drainage channel 531.

[0041] If rainwater overflows from the collection chamber 551, the overflowing rainwater flows through the outer circumference of the rotor 5 and the outer circumference of the waterproof enclosure 54 to the space between the gear seat 4 and the waterproof enclosure 54, and then through the gap between the edge drainage surface 67 of the cover plate 6 and the first mounting slot 44 and the water leakage gap 68 at the edge to be discharged into the cover cylinder 7.

[0042] After the rainwater is discharged into the cover cylinder 7, it will flow out through the wire hole 71. The conductive plate 51 on the rotor 5 and the contact plate 61 and terminal 62 on the cover plate 6 are not likely to come into contact with the rainwater, so as to avoid rainwater corrosion that could lead to short circuit or poor power supply of the ignition lock.

[0043] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
