In addition, for simplicity and clarity of understanding, elements having the same structure or function in some of the figures may be shown only schematically or only schematically.

Before the faucet lock of the embodiment of the present application is explained, an application scenario of the faucet lock is briefly explained to facilitate understanding.

To the problem that provides in the background art, this application provides a tap lock, and this tap lock can send unblock feedback signal to the well accuse portion of electric motor car reliably to make and guarantee that the spring bolt is located under the condition of unblock position, the electric motor car can normally ride, thereby has solved user's puzzlement. Specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, the faucet lock of the present embodiment includes a parking lock portion including a second slider 22 and a latch bolt 21 mounted on the second slider 22, an emergency unlocking portion, and a position detection portion, and the latch bolt 21 reciprocates between a locked position and an unlocked position following the second slider 22; the emergency unlocking part comprises a pulling piece 31 and a first sliding piece 32 which are connected with each other, one end of the pulling piece 31 is connected with the first sliding piece 32, and the other end of the pulling piece is used as a force application end; the first sliding part 32 is located in front of the second sliding part 22, and when the pulling part 31 is pulled backwards, the first sliding part 32 moves backwards synchronously along with the pulling part 31 and pushes the second sliding part 22 to move backwards so as to drive the lock tongue 21 to move towards the unlocking position; the position detection part comprises a first position sensor 41 and a second position sensor 42 which are electrically connected with a central control part of the electric vehicle, the first position sensor 41 corresponds to the first sliding part 32 and can be triggered by the first sliding part 32 to send an unlocking feedback signal to the central control part when the bolt 21 reaches an unlocking position; the second position sensor 42 corresponds to the second slider 22, and can be triggered by the second slider 22 to send an unlocking feedback signal to the central control unit when the lock tongue 21 reaches the unlocking position.

In the present application, a front-back direction X, a left-right direction Y, and an up-down direction Z are defined as three orthogonal directions, wherein a reciprocating direction of the lock tongue 21 is consistent with the front-back direction X, and the lock position is located in front of the unlock position; the first slider 32 and the second slider 22 are distributed in the left-right direction Y.

Under the condition of adopting the technical scheme, when the second position sensor 42 has normal functions and no fault exists, the second sliding part 22 drives the bolt 21 to move backwards, when the bolt 21 reaches the unlocking position, the second sliding part 22 can trigger the second position sensor 42, and then the second position sensor 42 can send an unlocking feedback signal to a central control part of the electric vehicle, so that the electric vehicle is allowed to normally ride; in this process, since the first slider 32 is located in front of the second slider 22 and no pulling force is applied to the pulling member 31, the first slider 32 is not interfered by the second slider 22 and the first position sensor 41 cannot be triggered. When the second position sensor 42 fails and cannot send an unlocking feedback signal to the central control portion, the emergency unlocking portion may be activated, that is, a pulling force is applied to the pulling member 31 at the force application end, so that the first sliding member 32 moves backwards, the first sliding member 32 pushes the second sliding member 22 to move backwards, and the lock tongue 21 is further driven to reach the unlocking position, at this time, the first sliding member 32 may trigger the first position sensor 41, and the central control portion allows the electric vehicle to normally ride after receiving the unlocking feedback signal sent by the first position sensor 41.

As can be seen, the emergency unlocking part and the parking locking part are independent of each other, and the backward movement of the second slider 22 does not affect the first slider 32. When the second position sensor 42 functions well, only the parking lock portion is used. When only second position sensor 42 broke down, exerted pulling force behind pulling piece 31, first position sensor 41 just did the spare part with emergent unblock portion cooperation in order to realize sending the mesh of unblock feedback signal to well accuse portion as, and then guaranteed that the electric motor car can normally ride. Therefore, the first position sensor 41 has low use frequency and long service life, and can provide reliable guarantee for realizing normal safe riding of the electric vehicle when the second position sensor 42 is broken.

Therefore, the faucet lock provided by the application is high in reliability and can provide reliable guarantee for safe riding of the electric vehicle.

In one possible implementation manner, the faucet lock further comprises a shell, and the parking locking part, the emergency unlocking part and the position detection part are all assembled in the shell; the emergency unlocking portion further comprises a first energy accumulating member 33 and a first elastic member 34, the first energy accumulating member 33 is fixed on the housing of the tap lock, and the first elastic member 34 is connected between the first energy accumulating member 33 and the first slider 32.

Under the condition of adopting the technical scheme, the first elastic piece 34 can provide elastic holding force and elastic resetting force for the first sliding piece 32, the elastic holding force can enable the first sliding piece 32 to be kept at an idle position in front of the second sliding piece 22 (at the idle position, the first sliding piece 32 is far away from the first position sensor 41), when the emergency unlocking part needs to be started, pulling force is applied to the pulling piece 31, the first sliding piece 32 is enabled to move backwards by overcoming the elastic force of the first elastic piece 34, and then the lock tongue 21 is driven to move towards the locking position; when it is desired to return the first slider 32 to the rest position, the pulling force exerted on the pulling member 31 is removed, and the first slider 32 can be moved forward back to the rest position by the first elastic member 34, so as not to interfere with the normal use of the second slider 22.

In a possible embodiment, the faucet lock further comprises a fastener, the housing is provided with an anchoring post 17, the anchoring post 17 is provided with an internally threaded hole, the first energy storage member 33 is provided with a threaded through hole 332, and the fastener passes through the threaded through hole 332 to be in threaded connection with the internally threaded hole. In this way, the first energy accumulating member 33 can be fixed inside the housing. Wherein the fastener may be a bolt or a screw.

In a possible embodiment, the first elastic element 34 is a first compression spring, the first energy storage element 33 has a first receiving through hole/a first receiving groove, the front side wall and the rear side wall of the first receiving through hole/the first receiving groove are respectively provided with a first pin 331, the front end and the rear end of the first compression spring are respectively sleeved on the two first pins 331, and the first compression spring extends out of the upper surface and/or the lower surface of the first energy storage element 33; the first sliding member 32 includes a first sliding body 321 and a first external connection plate 322 connected to each other, the first external connection plate 322 is used for pushing against the first sliding member 32 and triggering the first position sensor 41, the first sliding body 321 has a first groove 3211 extending along the front-back direction X, an upper side wall and/or a lower side wall of the first groove 3211 is respectively provided with a first sinking groove 3212, the first energy storage member 33 is inserted into the first groove 3211, an upper side and/or a lower side of the first compression spring extends into the corresponding first sinking groove 3212, and two ends of the first compression spring respectively push against the front side wall and the rear side wall of the first sinking groove 3212.

With the above technical solution, the two first pins 331 can stably keep the first compression spring in the first accommodating through hole/the first accommodating groove, so that two ends of the first compression spring can stably abut against the front and rear side walls of the first sinking groove 3212 to provide stable elastic retaining force and elastic restoring force for the first sliding element 32; furthermore, the first sliding member 32 can slide relative to the first energy accumulating member 33 in the front-rear direction X, and the first elastic member 34 can restrain the first sliding member 32 in the front-rear direction X to prevent the first sliding member 32 from slipping off the first energy accumulating member 33. In addition, because the first energy storage member 33 is inserted into the first groove 3211 and the first elastic member 34 is located in the first groove 3211, the first energy storage member 33 can limit the position of the first sliding member 32 in the vertical direction Z, so that the volume of the emergency unlocking portion can be reduced, and the volume of the faucet lock can be reduced.

In a possible example, the first sliding body 321 extends along a front-back direction X, the extending direction of the first external connecting plate 322 is perpendicular to the front-back direction X, the first external connecting plate 322 is connected to the front end of the first sliding body 321, the left side of the first external connecting plate 322 corresponds to the first position sensor 41 for triggering the first position sensor 41, and the right side corresponds to the second sliding member 22 for pushing against the second sliding member 22.

In an example, the first energy storage member 33 has the first accommodating through hole, an axial direction of the first compression spring is consistent with a radial direction of the first accommodating through hole, when the first compression spring is located in the first accommodating through hole, upper and lower sides of the first compression spring both extend out of the first accommodating through hole, an upper side wall and a lower side wall of the first groove 3211 are respectively provided with the first sinking grooves 3212, upper and lower sides of the first compression spring extend into the corresponding first sinking grooves 3212, and front and rear side walls of each first sinking groove 3212 can be abutted by two ends of the first compression spring. In this way, the first elastic element 34 can apply the same elastic force to the first sliding element 32 on both upper and lower sides of the first groove 3211, which is beneficial to keep the first sliding element 32 balanced on the first energy accumulating element 33, so as to realize stable and smooth sliding.

In one embodiment, the first energy accumulating member 33 has a limit step surface extending in the front-rear direction X, the housing has a first limit plate 14 extending in the front-rear direction X, and the first sliding body 321 is located between the limit step surface and the first limit plate 14. Under the condition of adopting this technical scheme, on left and right direction Y, spacing step face and first limiting plate 14 are spacing first slider 32 jointly to ensure that first slider 32 slides along fore-and-aft direction X steadily.

In one example, the housing may include an upper cover 11 and a lower cover 12, the parking lock part, the position detecting part may be installed in the lower cover 12, the fixing member may be located at an inner side of the upper cover 11, and the first limit plate 14 may be located at an inner side of the upper cover 11. Therefore, the upper part and the lower part of the earthworm head lock can be conveniently and separately assembled, namely, the first sliding part 32 and the first energy storage part 33 are assembled at the inner side of the upper cover 11; the parking lock portion, the position detecting portion may be installed in the lower case 12 and then the two portions are assembled together.

In one possible implementation, the first slider 32 has a rearwardly protruding limiting protrusion 3221, and the second slider 22 has a limiting groove correspondingly engaged with the limiting protrusion 3221. With this technical solution, when the first sliding part 32 moves backwards to push against the second sliding part 22, the limiting protrusion 3221 may extend into the limiting groove, so that when the first sliding part 32 and the second sliding part 22 push against each other, the two parts are relatively displaced in the up-down direction Z or the left-right direction Y, thereby ensuring that the second sliding part 22 is reliably pushed to move backwards.

Wherein, the position-limiting protrusion 3221 may be located on the first outer connecting plate 322, and the position-limiting protrusion 3221 may gradually decrease in the protrusion direction, so as to facilitate the position-limiting protrusion 3221 to smoothly extend into the position-limiting groove.

In a possible implementation manner, the end of the pulling member 31 has a stop head 311, the first sliding member 32 has a first avoiding groove or a first avoiding hole for the pulling member 31 to pass through, and the stop head 311 stops at the front side of the first avoiding groove or the first avoiding hole. Under the condition of adopting the technical scheme, the first sliding part 32 can be pulled only by passing the pulling part 31 through the first avoidance groove or the first avoidance hole and enabling the stop head 311 to be positioned at the front side of the first avoidance groove or the first avoidance hole; the assembly process is simple and quick.

Wherein, the first avoiding groove or the first avoiding hole may be located on the first external connection plate 322.

In one example, the first slider 32 may have the above-mentioned first avoidance groove, the notch of the first avoidance groove faces the housing, and the housing (which may be the upper cover 11) can block the notch of the first avoidance groove when the assembly is completed. Therefore, when the assembly is carried out, the pulling piece 31 is placed into the first avoiding groove from the notch, and the assembly is simpler and more convenient.

In one example, the first escape groove or the first escape hole may be located on the position limiting protrusion 3221.

In one example, the front side of the first slider 32 may have a receiving groove corresponding to the restricting protrusion 3221 to receive the stopper 311. This makes it possible to reduce the dimension of the stopper 311 in the front-rear direction X after the stopper is assembled with the first slider 32, thereby facilitating reduction in the volume of the faucet lock.

In one possible implementation, the second sliding member 22 has a second avoiding groove or a second avoiding hole, and the pulling member 31 passes through the second avoiding groove or the second avoiding hole to connect with the first sliding member 32. Under the condition of adopting the technical scheme, the second avoidance groove or the second avoidance hole is arranged on the second sliding part 22, so that the pulling part 31 can be avoided, the volume of the faucet lock is favorably reduced, and the pulling part 31 is favorably ensured to extend along the front-back direction X under the limitation of the second avoidance groove or the second avoidance hole on the basis of the two-point line principle, so that the pulling force applied to the first sliding part 32 is ensured to be along the front-back direction X, and the first sliding part 32 can stably and smoothly slide backwards.

In one example, the second slider 22 may have the above-mentioned second avoiding groove, the notch of which faces the housing, and the housing (which may be the upper cover 11) can block the notch of the second avoiding groove when the assembly is completed. Therefore, when the device is assembled, the pulling piece 31 is placed into the second avoidance groove from the notch, and the device is simpler and more convenient.

In one example, the second avoidance groove or the second avoidance hole may be located at the spacing groove.

In a possible embodiment, it may be dimensioned such that the upper ends of the first and second external plates 322 and 222 are abutted against the upper cover 11 when the upper cover 11 and the lower case 12 are coupled together; the upper cover 11 has a passing groove 111, and the first avoiding groove on the first sliding member 32 and the second avoiding groove on the second sliding member 22 are both located right below the passing groove 111. Thus, after the upper cover 11 and the lower cover 12 are connected, the pulling member 31 is aligned and then placed in the passing groove 111 along the vertical direction Z, so that the pulling member 31 automatically enters the first avoiding groove and the second avoiding groove under the action of gravity, and the stopping head 311 is located in front of the first avoiding groove. Therefore, the technical scheme can enable the faucet lock to be assembled simply and conveniently. In addition, the first external connection plate 322 and the second external connection plate 222 can also provide support for the upper cover 11, and enhance the structural strength of the faucet lock.

In one example, the housing further includes a cover plate 13, and the cover plate 13 may cover the notch of the through groove 111 and be connected to the upper cover 11, so as to limit the pulling member 31 in the first and second avoidance grooves.

In one example, the pulling member 31 is a pulling wire, and the emergency unlocking portion further includes a protection tube 35, and the pulling wire extends into the protection tube 35 after extending out of the through groove 111.

In one example, the protection tube 35 has a limiting groove thereon, the cover plate 13 has a clamping portion adapted to the limiting groove, and after the cover plate 13 is fixed on the upper cover 11, the clamping portion is located in the limiting groove, so that the protection tube 35 can be limited and fixed outside the upper cover 11, and the protection can be provided for the pull wire.

In one possible implementation, the first position sensor 41 is a microswitch, and/or the second position sensor 42 is a microswitch. The microswitch has strong anti-interference capability and high reliability, and is beneficial to improving the reliability of the faucet lock.

In a possible implementation manner, the position detection part further includes a PCB 43, and the first position sensor 41 and the second position sensor 42 are both mounted on the PCB 43 and electrically connected to the central control part through the PCB 43. Under the condition of adopting the technical scheme, the PCB 43 can replace a common wire to realize electric connection, so that the use of the common wire in the faucet lock is reduced; the PCB 43 may also serve as a mounting structure for the first and second position sensors 41 and 42, facilitating the fixing of the first and second position sensors 41 and 42 in the housing; therefore, the technical scheme achieves the effects of simplifying the structure and facilitating assembly. In one possible implementation, the parking lock part further comprises a second energy storage member 23, a second elastic member 24, a transmission assembly and a driving member; the second elastic element 24 is connected between the second sliding element 22 and the second energy accumulating element 23; the transmission assembly is connected between the second energy accumulating member 23 and the driving member.

Under the condition of adopting the technical scheme, the driving piece can drive the second energy storage piece 23 to move through the transmission assembly, the second energy storage piece 23 can drive the second sliding piece 22 to reciprocate between the unlocking position and the locking position through the second elastic piece 24, and the second elastic piece 24 plays a role in transmitting power to the second sliding piece 22; when the second position sensor 42 is broken and the emergency unlocking part needs to be activated to push the lock tongue 21 to the unlocking position, the second elastic member 24 may allow the second sliding member 22 to slide on the second energy accumulating member 23, thereby moving the lock tongue 21 to the unlocking position.
