Description

Technical Field

[0001] This application relates to the field of electric vehicle lock technology, and in particular to a wireless beadlock. Background Technology

[0002] A steering lock is a type of lock mainly installed on electric vehicles and motorcycles. Its main purpose is to lock the steering wheel of the electric vehicle or motorcycle after it is parked to prevent the electric vehicle or motorcycle from being stolen.

[0003] A typical faucet lock structure usually includes a locking pin, an electric unlocking mechanism, and a manual unlocking mechanism. The electric unlocking mechanism includes a circuit board, a power storage tank, a gear set, and a motor. The manual unlocking mechanism includes a pull cord and a sliding assembly that moves the locking pin. When unlocked electrically, the motor drives the gear set to rotate, which in turn moves the power storage tank, thus moving the locking pin to unlock or lock. When unlocked manually, the pull cord moves the sliding assembly, which in turn moves the locking pin to unlock.

[0004] The faucet lock contains a circuit board and a limit switch to detect the unlocking status. The circuit board typically has a predetermined sliding distance for the locking pin. When the customer requests to unlock the faucet lock by pulling a rope, the rope needs to be pulled a short distance to engage the limit switch, causing it to activate prematurely and display a timely reading on the instrument. Utility Model Content

[0005] In order to shorten the travel distance when unlocking the faucet lock by pulling the rope, and to activate the limit switch in advance, this application provides a wireless faucet lock.

[0006] This application provides a wireless head lock, which adopts the following technical solution:

[0007] A wireless faucet lock includes a housing, a locking pin, and a circuit board disposed within the housing. A through hole is formed within the housing, and the locking pin slides along the length of the through hole. A pull block is slidably disposed within the housing, and a pull rope is attached to the pull block. The pull rope drives the pull block to slide, thereby unlocking the locking pin. A limit switch is electrically connected to the circuit board. A travel compensation structure is disposed on the pull block, comprising an abutment block and a compensation spring. The abutment block is slidably connected to the pull block. The compensation spring, the abutment block, and the limit switch are arranged in a row. When the pull rope drives the pull block to slide and unlock the locking pin, the abutment block slides close to and abuts against the limit switch.

[0008] By adopting the above technical solution, the pull rope is set on the pull block, and the abutment block is slidably connected to the pull block. When it is necessary to use the pull rope to drive the pull block to slide and unlock the lock pin, the pull block slides and drives the abutment block to slide. When the abutment block abuts the limit switch, the instrument displays that the faucet lock is unlocked. The abutment block and the compensation spring make it possible for the pull block to abut the limit switch even with a shorter pulling stroke, shortening the travel distance when the pull rope unlocks the faucet lock and activating the limit switch in advance.

[0009] Optionally, the pull block is provided with a return spring, and the pull block has a receiving groove for accommodating the return spring. One end of the return spring is disposed on the groove wall of the housing receiving groove, and the other end is disposed on the housing. The spring force direction of the return spring is parallel to the sliding direction of the locking pin. When the pull rope drives the pull block to slide, the return spring is compressed, and the return spring is used to reset the pull block.

[0010] By adopting the above technical solution, when the pulling action drives the pulling block to move, the return spring is compressed. When the faucet lock is unlocked, the return spring causes the pulling block to return to its original position.

[0011] Optionally, an anti-detachment block is provided at one end of the abutment block near the compensating spring. The outer diameter of the anti-detachment block is larger than that of the abutment block. A sliding groove is provided on the pulling block for the abutment block to slide. An anti-detachment groove is provided on the pulling block for the anti-detachment block to slide. The anti-detachment groove is connected to the abutment groove. The compensating spring drives the anti-detachment block to abut against the side wall of the anti-detachment groove.

[0012] By adopting the above technical solution, the anti-detachment block prevents the abutment block from detaching from the pulling block, and at the same time, when the compensation spring is compressed, the abutment block slides stably.

[0013] Optionally, the circuit board is electrically connected to a connector, the contact of which is plugged into the circuit board. The connector is used to electrically connect to the electric vehicle dashboard, and the contact of the limit switch is plugged into the circuit board.

[0014] By adopting the above technical solution, the connectors do not require welding and there is no wiring harness, making the assembly of the faucet lock simpler.

[0015] Optionally, the limit switch includes a first limit switch and a second limit switch. The first limit switch is used to sense the abutment block and also includes an electric unlocking mechanism that drives the lock pin to slide. The second limit switch is used to sense the unlocking state of the lock pin.

[0016] By adopting the above technical solution, the first limit switch is used to allow the abutment block to abut when the pull rope drives the pull block to slide, so that the instrument displays that the faucet lock is unlocked, and the second limit switch is driven by the electric unlocking mechanism to abut.

[0017] Optionally, it also includes a sliding assembly that drives the locking pin to slide. The sliding assembly includes a sliding block and an energy storage box. The energy storage box includes a connecting block and a sliding spring. The connecting block is slidably disposed within the housing. The locking pin is disposed on the sliding block. When the pulling block drives the locking pin to unlock, the pulling block abuts against the sliding block and slides. The connecting block has a placement groove. The sliding spring is disposed on opposite sides of the placement groove. The sliding block has an assembly groove for accommodating the sliding spring. The radial ends of the sliding spring are located on opposite sides of the assembly groove. The spring force direction of the sliding spring is the same as the sliding direction of the locking pin. When the electric unlocking mechanism drives the connecting block to slide, the connecting block drives the sliding block to slide through the sliding spring, thus unlocking or locking the faucet lock.

[0018] By adopting the above technical solution, the connecting block drives the sliding block to slide through the compression of the sliding spring, thereby realizing the locking and unlocking of the faucet lock. The structure is simple and easy to install.

[0019] Optionally, the electric unlocking mechanism includes a motor, a gearbox, and a connecting gear. The input end of the gearbox is coaxially fixed to the output end of the motor, and the output end of the gearbox is coaxially fixed to the connecting gear. A rack is provided on the connecting block, and the connecting gear meshes with the rack. When the motor drives the connecting gear to rotate, the connecting block slides toward or away from the through hole.

[0020] By adopting the above technical solution, the electric unlocking mechanism drives the gearbox to rotate through the motor, and the rotating connecting gear drives the connecting block to slide. The rack is set on the connecting block to improve assembly efficiency and simplify installation. At the same time, the connecting gear and the connecting block are easy to assemble.

[0021] Optionally, the rack and the connecting block are integrally cast.

[0022] By adopting the above technical solution, the rack and connecting block are integrally cast, which improves the assembly efficiency of the sliding component and provides high structural strength for the rack and connecting block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The pulling action causes the pulling block to slide. Through the abutment block and the compensation spring, the limit switch can be abutted even when the sliding stroke of the pulling block is short, thus shortening the stroke distance when the rope is pulled to unlock the faucet lock and activating the limit switch in advance.

[0025] 2. The anti-detachment block prevents the abutment block from detaching from the pulling block, while also stabilizing the sliding of the abutment block;

[0026] 3. The connectors require no welding and have no wiring harness, making faucet lock assembly simpler. Attached Figure Description

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] This application discloses a wireless beam faucet lock. (Refer to...) Figure 1 , Figure 2 , Figure 3The wireless faucet lock includes a housing 1, a locking pin 2, and a circuit board 3 disposed inside the housing 1. A through hole 51 is provided inside the housing 1, and the locking pin 2 slides along the length of the through hole 51. A pull block 52 is slidably connected inside the housing 1, and a pull rope 53 is fixed on the pull block 52. The pull rope 53 drives the pull block 52 to slide, thereby driving the locking pin 2 to unlock.

[0037] Reference Figure 2 , Figure 4 , Figure 5 The pull block 52 is provided with a stroke compensation structure 521, which includes an abutment block 5211 and a compensation spring 5212. The abutment block 5211 is slidably connected to the pull block 52, and the compensation spring 5212, the abutment block 5211 and the limit switch 6 are arranged in a row.

[0038] Reference Figure 2 , Figure 3 , Figure 4 Circuit board 3 is electrically connected to limit switches 6. Limit switches 6 include a first limit switch 61 and a second limit switch 62. The first limit switch 61 is used to sense the abutment block 5211, and the second limit switch 62 is used to sense the unlocked state of the locking pin 2 when the electric unlocking mechanism 4 is unlocked. When the pull rope 53 drives the pull block 52 to slide and drive the locking pin 2 to unlock, the abutment block 5211 slides close to the limit switch 6 and abuts against the first limit switch 61. Circuit board 3 is electrically connected to a connector 76. The contact head of the connector 76 is inserted into circuit board 3, and the connector 76 is used to electrically connect to the electric vehicle dashboard. The contacts of the first limit switch 61 and the second limit switch 62 are also inserted into circuit board 3.

[0039] Reference Figure 4 , Figure 5 An anti-detachment block 71 is fixed to one end of the abutment block 5211 near the compensating spring 5212. The outer diameter of the anti-detachment block 71 is larger than the outer diameter of the abutment block 5211. A sliding groove 72 for sliding the abutment block 5211 is provided on the pulling block 52, and an anti-detachment groove 73 for sliding the anti-detachment block 71 is provided on the pulling block 52. The anti-detachment groove 73 is connected to the abutment groove, and the compensating spring 5212 drives the anti-detachment block 71 to abut against the side wall of the anti-detachment groove 73.

[0040] Reference Figure 3 , Figure 4 A return spring 74 abuts against the pull block 52. The pull block 52 has a receiving groove 75 for accommodating the return spring. One end of the return spring 74 abuts against the wall of the receiving groove 75, and the other end abuts against the inside of the housing 1. The direction of the spring force of the return spring 74 is parallel to the sliding direction of the locking pin 2. When the pull rope 53 drives the pull block 52 to slide, the return spring is compressed, and the return spring 74 is used to reset the pull block 52.

[0041] Reference Figure 2 , Figure 6 , Figure 7 The wireless faucet lock also includes a sliding assembly 8 that drives the faucet lock to slide. The sliding assembly 8 includes a sliding block 81 and an energy storage box 82. The energy storage box 82 includes a connecting block 821 and a sliding spring 822. The connecting block 821 is slidably connected to the housing 1, and the locking pin 2 is fixed to the sliding block 81. When the pulling block 52 drives the locking pin 2 to unlock, the pulling block 52 abuts against the sliding block 81 and slides. The connecting block 821 has a placement groove 91, and the sliding spring 822 abuts against the opposite sides of the placement groove 91. The sliding block 81 has an assembly groove 92 for accommodating the sliding spring 822. The radial ends of the sliding spring 822 are located on opposite sides of the assembly groove 92, and the direction of the spring force of the sliding spring 822 is the same as the sliding direction of the locking pin 2. When the electric unlocking mechanism 4 drives the connecting block 821 to slide, the connecting block 821 drives the sliding block 81 to slide through the sliding spring 822, thus unlocking or locking the faucet lock.

[0042] Reference Figure 2 , Figure 6 , Figure 7 The electric unlocking mechanism 4 includes a motor 41, a gearbox 42, and a connecting gear 43. The input end of the gearbox 42 is coaxially fixed to the output end of the motor 41, and the output end of the gearbox 42 is coaxially fixed to the connecting gear 43. A rack 93 is fixed on the connecting block 821, and the rack 93 and the connecting block 821 are integrally cast. The connecting gear 43 meshes with the rack 93. When the motor 41 drives the connecting gear 43 to rotate, the connecting block 821 slides towards or away from the through hole 51. When the connecting block 821 slides away from the pulling block 52, the sliding block 82 abuts against the second limit switch 62, and the instrument displays that the auger lock is unlocked.

[0043] The implementation principle of a wireless faucet lock according to an embodiment of this application is as follows: When the faucet lock needs to be unlocked, the motor 41 drives the connecting block 821 to slide away from the pulling block 52, thus unlocking the faucet lock. At the same time, the pull rope 53 can also drive the pulling block 52 to slide. The abutment block 5211 is slidably connected to the pulling block 52. When the pull rope 53 drives the pulling block 52 to slide, the sliding of the pulling block 52 drives the abutment block 5211 to slide. The abutment block 5211 and the compensating spring 5212 ensure that the pull rope 53 has a short pulling stroke. When the first limit switch 61 is engaged, the instrument displays that the faucet lock is unlocked. The first limit switch 61 is activated in advance. When the pull rope 53 continues to pull, the first limit switch 61 is pressed, and the compensation spring 5212 is compressed, causing the faucet lock to unlock. Through the abutment block 5211 and the compensation spring 5212, the pull rope 53 engages the first limit switch 61 in advance when pulling a shorter distance, shortening the travel distance of the pull rope 53 when unlocking the faucet lock and activating the limit switch 6 in advance.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
