Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle accessories, in particular to an electronic tap lock. Background Art

[0002] The handlebar lock is the core anti-theft component of bicycles, motorcycles and electric vehicles. It mainly prevents theft by locking the relative rotation of the front fork stem and the frame. It has gradually developed into a dual mode of "electronic unlocking + mechanical unlocking", but the existing technology still has obvious shortcomings.

[0003] Among them, an electronic faucet lock with an existing authorized utility model patent (authorization announcement number: CN219382672U) is a typical solution. It realizes the electric extension and retraction of the lock tongue through a circuit board (including a signal receiving and execution module), an execution motor, a worm-gear transmission unit and an intermittent transmission device, while retaining the mechanical unlocking mechanism of "mechanical key + lock cylinder + transmission part" to form a dual unlocking mode; and uses Hall elements (lower Hall, upper Hall) in conjunction with magnets to monitor the status of the lock tongue and transmission plate, and uses a micro switch to feedback the mechanical unlocking position, attempting to improve ease of use and status monitorability.

[0004] However, this comparative document solution still has key flaws in practical application:

[0005] Insufficient state monitoring accuracy and anti-interference performance: The accuracy bottleneck of Hall elements stems from the inherent defects of the electromagnetic induction principle, which is easily affected by temperature and magnetic fields and the accuracy of state judgment;

[0006] Core components lack special sealing and have weak environmental adaptability: The actuator motor, circuit board, and Hall element rely only on the basic protection of the lock housing. There is no sealing structure, and rain and dust can easily penetrate and cause component failure. Utility Model Content

[0029] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0030] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0031] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] Example 1:

[0033] like Figure 1 As shown, in a specific embodiment of the present invention, an electronic faucet lock includes a lock housing 1, a micro motor 2, a worm gear 3, a gear set 4, a latch 5, a slider 6, a rack 7, a return spring 8, a cable 9, a cable block 10, a PCB board 11 and a position sensing element 12. The position sensing element 12 is characterized in that the position sensing element 12 includes a plurality of travel sensing members 121 and a plurality of elastic triggering members 122. Each travel sensing member 121 is mounted on the PCB board 11, and each elastic triggering member 122 is floatingly mounted within the lock housing 1. One end of each elastic triggering member 122 is used to trigger the corresponding travel sensing member 121, and the other end is respectively provided in a one-to-one correspondence with the slider 6, the rack 7, and the cable block 10.

[0034] In this embodiment of the present application, the travel sensing element 121 is a travel switch.

[0035] In this embodiment of the present application, a card plate 13 is fixed on the slider 6, a mounting groove 26 is opened in the middle of the card plate 13, a spring 28 is provided in the mounting groove 26, a slide groove 14 is opened on the rack 7, a spring groove 27 is opened in the middle of the slide groove 14, the card plate 13 and the slide groove 14 are slidably matched, and the two ends of the spring 28 are respectively abutted against the two ends of the spring groove 27.

[0036] like Figures 1 to 11As shown, due to the adoption of the above structure, after the micro motor 2 is started, the worm gear 3 and the gear set 4 are driven to rotate, and the gear set 4 drives the rack 7 to move along the preset trajectory. During the movement of the rack 7, its slide groove 14 forms a sliding fit with the card plate 13 on the slider 6. The spring 28 in the slide groove 14 is compressed or reset with the relative displacement of the rack 7 and the slider 6, which provides a buffer to avoid the micro motor 2 from being blocked and damaged when the latch 5 is stuck; at the same time, when any one of the rack 7 and the cable block 10 moves toward the elastic trigger member 122, it drives The slider 6 approaches the elastic trigger part 122 until the slider 6 drives it. When the slider 6 moves to contact the elastic trigger part 122, it will push the elastic trigger part 122 to move in the direction of the travel sensing part 121. After the push rod 1221 triggers the travel switch, the travel switch corresponding to the slider 6 (the latch 5 is fixed on it) transmits the unlocking signal to the vehicle host through the wiring harness; after the vehicle host receives the signal from the travel sensing part 121 corresponding to the rack 7 and the slider 6 or the signal from the cable block 10 and the slider 6, it determines that the steering lock is in the unlocked state and allows the vehicle to start and drive.

[0037] The function of the return spring 8 is to compress the return spring 8 when the faucet lock is in the locked state, and to provide an unlocking force to the latch 5 when the gear set or the slider 6 and the rack 7 are structurally damaged, so as to ensure that the latch 5 will not extend and lock during the operation of the vehicle and cause an accident.

[0038] Its beneficial effects are:

[0039] The micro switch of this application changes the judgment logic from "indirect conversion" to "direct contact" through the structural innovation of "mechanical triggering + elastic limiting + layered sealing", making the judgment accuracy of this application naturally better than Hall.

[0040] Example 2:

[0041] The difference from Example 1 is that, in addition to the structural features of the aforementioned embodiments, in the specific embodiment of the present utility model, the elastic trigger member 122 includes a push rod 1221, a push rod spring 1222 and a limit member 15. The push rod 1221 is floatingly inserted on the partition inside the lock housing 1, one end is used to trigger the travel switch, and the other end corresponds to the slider 6, the rack 7 or the cable block 10. The limit member 15 is arranged in the lock housing 1, which is used to limit the travel of the push rod 1221 away from the elastic trigger member 122, and the push rod spring 1222 is used to apply a force on the push rod 1221 away from the travel switch.

[0042] like Figures 8 to 9As shown, due to the adoption of the above-mentioned structure, the push rod 1221 of the elastic trigger member 122 is floatingly inserted on the partition of the lock shell 1, and the push rod spring 1222 always applies a force on the push rod 1221 away from the travel switch, so that the push rod 1221 maintains its initial position when it is not triggered; when the slider 6, the rack 7 or the cable block 10 applies pressure to the push rod 1221, the push rod 1221 overcomes the elastic force of the push rod spring 1222 and moves toward the travel switch until the travel switch is triggered and the unlocking signal is transmitted; when the trigger component leaves the push rod 1221, the elastic force of the push rod spring 1222 pushes the push rod 1221 to reset, disengage from the contact with the travel switch, and the travel switch stops transmitting the signal, thereby realizing automatic resetting of the triggered state; at the same time, the limit member 15 in the lock shell 1 can limit the maximum travel of the push rod 1221 away from the travel switch, thereby preventing the push rod 1221 from running out of the preset movement range due to the force of the push rod spring 1222.

[0043] Its beneficial effects are:

[0044] This solves the "unreliable reset" problem of state monitoring in the prior art: the prior art uses the relative position of the Hall element and the magnet to sense the state, without a dedicated reset structure. The Hall element is easily displaced by the magnet due to vibration, resulting in state signal drift. The push rod spring 1222 of this embodiment provides a stable reset force for the push rod 1221, which can be reset immediately after triggering. The limit member 15 further limits the travel of the push rod 1221, ensuring that the push rod 1221 always maintains an adaptive position with the trigger component and the travel switch, avoiding the signal misjudgment that may be possible in the prior art.

[0045] Adaptable to the existing technology transmission framework without major modifications: based on the existing technology "motor-worm-gear set 4-rack 7" core transmission, only the push rod 1221, push rod spring 1222 and limiter 15 are added, without adjusting the original motor and gear set 4 layout, reducing the cost of technology iteration and improving triggering reliability.

[0046] Example 3:

[0047] The difference from Example 2 is that, in addition to the structural features of the aforementioned embodiments, in the specific embodiment of the present utility model, the limit member 15 includes a limit ring 151 and a limit plate 152 with a groove, the limit plate 152 is fixed in the lock housing 1, the limit ring 151 is fixed on the push rod 1221, one side of which abuts against the end of the push rod spring 1222 away from the travel switch, and the other side abuts against the limit plate 152, and the outer wall of the push rod 1221 slides in cooperation with the groove.

[0048] like Figures 8 to 9As shown, due to the adoption of the above structure, when the push rod 1221 moves, its outer wall forms a sliding fit with the groove of the limit plate 152, and the groove provides a precise movement guide for the push rod 1221, ensuring that the push rod 1221 always moves in a direction perpendicular to the limit switch; one side of the limit ring 151 fixed on the push rod 1221 abuts against the end of the push rod spring 1222 away from the limit switch, and the other side abuts against the limit plate 152. When the push rod 1221 is reset under the action of the push rod spring 1222, the limit ring There is a pair of 151, which can accurately limit the reciprocating stroke of the push rod 1221 in conjunction with the abutment relationship with the limit plate 152, so as to prevent the push rod 1221 from being over-retracted and damaging the travel switch and being over-reset and out of the effective installation position; when the trigger component pushes the push rod 1221, the limit ring 151 compresses the push rod spring 1222 along with the push rod 1221 until the push rod 1221 triggers the travel switch, and the limit ring 151 located on the outside abuts against the outside of the limit plate 152 to prevent the push rod 1221 from excessively squeezing the travel switch.

[0049] Its beneficial effects are:

[0050] The structural stability is adaptable to harsh working conditions and is superior to the existing Hall elements: the existing Hall elements are easily affected by the motor magnetic field and external electromagnetic interference. The mechanical guide and limit structure of this embodiment is not affected by electromagnetic interference. In scenarios where the vehicle vibrates and the electromagnetic environment is complex, the triggering reliability is significantly higher than the existing Hall sensing method.

[0051] Example 4:

[0052] The difference from Example 3 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiment of the present utility model, the lock housing 1 includes an outer shell 101 and a sealed inner shell 102, the sealed inner shell 102 is fixed in the outer shell 101, the micro motor 2, the PCB board 11 and each stroke sensing component 121 are all completely arranged in the sealed inner shell 102, each elastic trigger component 122 is respectively sealed and penetrated on the outer wall of the sealed inner shell 102, the gear set 4 is arranged in the sealed inner shell 102, and its single gear engaged with the rack 7 extends out of the sealed inner shell 102.

[0053] In this embodiment of the present application, a sealing ring is provided between the gear extending out of the sealed inner shell 102 and the elastic triggering member 122 and the sealed inner shell 102 .

[0054] like Figures 8 to 9As shown, due to the adoption of the above structure, the sealed inner shell 102 of the lock housing 1 completely encloses the micro motor 2, the PCB board 11 and all the travel sensing parts 121 (travel switches) to form a closed space; when the micro motor 2 drives the gear set 4 to rotate, the single gear in the gear set 4 that meshes with the rack 7 extends out of the sealed inner shell 102 and realizes transmission cooperation with the external rack 7; each ejector rod 1221 is sealed and penetrated through the outer wall of the sealed inner shell 102, and the connection between the gear extending out of the sealed inner shell 102 and each elastic triggering member 122 and the sealed inner shell 102 is sealed by a sealing ring; when the rack 7, the slider 6 or the cable block 10 triggers the ejector rod 1221, the ejector rod 1221 maintains a sealed state at the sealed penetration and completes the triggering action, and external impurities such as dust and water vapor cannot enter the interior through the gap of the sealed inner shell 102; after the travel switch on the PCB board 11 receives the trigger signal, it transmits it to the vehicle host through the wiring harness to complete the unlocking state determination.

[0055] Its beneficial effects are:

[0056] Fills the gap in the existing technology of "no special sealing protection": the existing technology only provides basic protection through the lock shell 1, and core components such as the micro motor 2, PCB board 11, and Hall element are easily corroded by rain and dust, leading to failure. The double sealing structure of "sealed inner shell 102 + sealing ring" in this embodiment completely places the motor, PCB board 11, and limit switch in a sealed space, and all protruding components (gear, push rod 1221) are equipped with sealing rings. The protection level far exceeds that of the existing technology, avoiding the problems of motor stalling and circuit board short circuit caused by environmental impurities in the existing technology.

[0057] Sealing and transmission are compatible, without affecting the core transmission efficiency of the existing technology: In this embodiment, only a single gear in the gear set 4 that meshes with the rack 7 extends out of the sealed inner housing 102, which not only ensures the sealing effect, but also makes the meshing efficiency of the gear and rack 7 basically consistent with the existing technology, achieving the compatibility of "high protection" and "high transmission efficiency", and solving the potential problem of "difficulty in balancing protection and transmission" in the existing technology;

[0058] Extend the life of core components and reduce the after-sales cost of existing technologies: The failure rate of unprotected motors and PCB boards 11 in existing technologies is relatively high (especially in humid environments). The sealing structure of this embodiment keeps the motor, limit switch, and PCB board 11 in a clean and dry environment, and the service life is more than doubled compared with existing technologies, reducing the frequency and cost of after-sales repairs caused by component damage.

[0059] Example 5:

[0060] The difference from Example 1 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiment of the present utility model, the sealed inner shell 102 includes a main shell 1021, a lower cover 1022 and an upper cover 1023, the main shell 1021 has a top cavity and a bottom cavity, the upper cover 1023 and the lower cover 1022 are used to seal the top cavity and the bottom cavity respectively, the PCB board 11 is fixed in the bottom cavity, the micro motor 2 and the gear set 4 are arranged in the top cavity, each elastic trigger member 122 extends into the top cavity, the top cavity and the bottom cavity are connected by a number of notches, which are used to allow each travel sensing member 121 to extend into the top cavity.

[0061] In this embodiment of the present application, the upper cover 1023 and the lower cover 1022 are fixed to the main shell 1021 by ultrasonic welding.

[0062] In this embodiment of the present application, the PCB board 11 is fixed in the bottom cavity by screws.

[0063] like Figure 5 、 Figure 6 and Figure 9 As shown, due to the adoption of the above structure, the main shell 1021 of the sealed inner shell 102 is divided into a top cavity and a bottom cavity, and the PCB board 11 is firmly fixed in the bottom cavity by screws, thereby preventing the PCB board 11 from being displaced due to the vibration of the entire vehicle; the micro motor 2 and the gear set 4 are installed in the top cavity, and a number of notches on the main shell 1021 connect the top cavity and the bottom cavity, so that the travel sensing member 121 (travel switch) on the PCB board 11 in the bottom cavity can extend into the top cavity through the notch and accurately align with the elastic trigger member 122 (elevator 1221) inside the top cavity; the upper cover 1 023. The lower cover 1022 is fixed to the main shell 1021 by ultrasonic welding, sealing the top cavity and the bottom cavity to form a completely enclosed space; during operation, the motor drives the gear set 4 in the top cavity to drive the rack 7 to move. After the rack 7, slider 6 or cable block 10 triggers the push rod 1221, the push rod 1221 touches the travel switch extending to the top cavity, and the signal is transmitted to the vehicle host through the PCB board 11. At the same time, the PCB board 11 of the bottom cavity is physically isolated from the transmission components of the top cavity to prevent oil and debris from contaminating the electronic components during the transmission process.

[0064] Its beneficial effects are:

[0065] This solves the problem of "contamination and interference caused by mixed components" in the prior art: in the prior art, the motor, gear set 4, PCB board 11, and Hall element are all installed in the same space of the lock housing 1. Oil from the transmission components can easily contaminate the PCB board 11 and the Hall element, causing electronic component failure. This embodiment uses a "top cavity (transmission components) - bottom cavity (electronic components)" partition design to achieve physical isolation, completely avoid oil and debris contamination, and reduce vibration interference on the PCB board 11 caused by motor operation. Compared with the prior art, the failure rate of electronic components is reduced by more than 80%;

[0066] The maintenance convenience is optimized and the maintenance difficulty of the existing technology is reduced: the existing technology requires the entire unlocking shell 1 to be disassembled during maintenance (the transmission and electronic components are mixed), which is time-consuming; the top cavity and the bottom cavity of this embodiment are independently sealed. During maintenance, the upper cover 1023 can be removed separately to inspect the motor and gear set 4, or the lower cover 1022 can be removed to inspect the PCB board 11, without the need for overall disassembly. The maintenance efficiency is more than twice that of the existing technology.

[0067] Example 6:

[0068] The difference from Example 1 is that, in addition to the structural features of the aforementioned embodiments, the specific embodiment of the present utility model also includes a cable sealing shell 16 and a cable sealing cover 17. The cable sealing shell 16 is fixed on the outer wall of the lock shell 1, and the cable block 10 is slidably installed in the lock shell 1 and the cable sealing shell 16. The cable sealing shell 16 is open at one end away from the latch 5, and a sealing sleeve 18 is installed therein. After the cable 9 passes through the sealing sleeve 18, it is fixed to the cable block 10. When the cable 9 is pulled, the cable block 10 drives the slider 6 to approach the position sensing element 12.

[0069] like Figures 2 to 3 As shown, due to the adoption of the above-mentioned structure, during electric unlocking, the micro motor 2 drives the gear set 4 to drive the rack 7 to move, and the rack 7 triggers the elastic trigger member 122 to trigger the travel switch. At the same time, the slider 6 moves along the preset trajectory, triggering the elastic trigger member 122 to trigger the travel switch, and the cable block 10 remains stationary in the space formed by the cable sealing shell 16 and the lock shell 1, and does not interfere with the electric unlocking process; pulling the cable 9, the cable 9 drives the cable block 10 to slide along the inner wall of the cable sealing shell 16 and the lock shell 1, and the cable block 10 drives the slider 6 to move in the unlocking direction. At this time, the rack 7 is meshed and fixed with the gear and remains stationary, and the latch 5 is mechanically unlocked with the movement of the slider 6 and the cable block 10; after unlocking, the cable block 10 presses against the top rod 1221 corresponding to the cable 9, and the slider 6 presses against the top rod 1221 corresponding to the latch 5 switch, and both switches transmit the unlocking signal to the vehicle host to complete the confirmation of the mechanical unlocking state.

[0070] Example 7:

[0071] The difference from Example 1 is that, in addition to the structural features of the aforementioned embodiments, in the specific embodiment of the present utility model, an inner contact block 19 is fixed on one side of the slider 6, an outer contact block 20 is fixed on the other side of the rack 7, a pair of baffles 21 are symmetrically arranged at the bottom of the slider 6, a middle contact block 22 is fixed on the top of the cable block 10, and the middle contact block 22 is slidably inserted between the pair of baffles 21, and a hook block 23 is fixed on the end of the top of the cable block 10 away from the stroke sensing part 121, which is used to cooperate with the baffle to pull the slider 6 for synchronous action when the cable block 10 approaches the stroke sensing part 121. The inner contact block 19, the outer contact block 20 and the middle contact block 22 respectively correspond to an elastic trigger member.

[0072] In this embodiment of the application, the bottom of the inner contact block 19 and the outer contact block 20 are each provided with a guide groove 24, which is respectively slidably connected with the upper cover 1023 and the outer shell 101 through a guide ridge 25, and the guide ridge 25 is parallel to the axis of the latch 5.

[0073] As shown in Figure 9 and Figure 10 With the above structure, when the rack 7 drives the slider 6 to approach the stroke sensing member 121, the inner contact block 19 on the slider 6 and the outer contact block 20 on the rack 7 are respectively in contact with the corresponding elastic trigger 122, which drives the corresponding stroke sensing member 121, and when the inhaul cable 9 is pulled to make the inhaul cable block 10 approach the stroke sensing member 121, the hook block 23 drives the pair of baffles 21 to make the slider 6 approach the stroke sensing member 121, and the inner contact block 19 on the slider 6 and the middle contact block 22 on the inhaul cable block 10 are respectively in contact with the corresponding elastic trigger 122, which drives the corresponding stroke sensing member 121. Through the sliding connection of the guide groove 24 and the guide ridge 25, the stability of the sliding of the rack 7 and the slider 6 along the axis of the latch 5 is improved.
