Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to an electric lock and a vehicle. Background Art

[0002] At present, the door locks of cars can be unlocked by electric and mechanical methods. In order to ensure the anti-theft performance of the door locks, the central locking function for cutting off external mechanical unlocking must also be retained simultaneously, and the central locking function also needs to be driven by a motor.

[0003] In the prior art, two motors are usually used to realize the electric unlocking and central control functions respectively, but the use of two motors is extremely disadvantageous to the weight reduction and cost of the whole vehicle. In response to this, some manufacturers have proposed to integrate the central lock and electric unlocking functions, that is, the two functions are driven by a common motor.

[0004] However, since the central lock must have two actions of unlocking / closing and these two actions usually require the motor to be driven in two opposite directions, and electric unlocking also requires the motor to be driven in at least one direction, this will cause motion superposition, that is, while the central control is unlocked or closed, the door lock is directly unlocked electrically, which is very dangerous. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electric lock and a vehicle, which can solve the problem in the prior art that the electric lock integrates central locking and electric unlocking functions, while avoiding the problem of the central control action directly opening the door.

[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments 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 without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0060] The electric lock and vehicle provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0061] See also Figures 1 to 10, an embodiment of the present application provides an electric lock, comprising: an unlocking device, the unlocking device is used to realize the release of the vehicle door; a driving device, the driving device can rotate in a first direction and a second direction, the first direction and the second direction are opposite; a central control device, the central control device and the driving device are movably connected, and the driving device can drive the central control device to switch between the first state and the second state; an electric opening device, the electric opening device is movably connected with the driving device and the unlocking device respectively; when the central control device is in the first state, the driving device rotates in the first direction, which can drive the central control device to switch to the second state and put the electric opening device in a non-working state; after the driving device stops driving, the driving device can reset and drive the electric opening device to be in a working state, and when the driving device rotates in the first direction again, the driving device can drive the electric opening device to move, thereby driving the unlocking device to realize the release of the vehicle door.

[0062] In the embodiment of the present application, the central control device has a first state and a second state. When the central control device is in the first state, the electric lock central control function is activated, and the electric unlocking function can be realized; when the central control device is in the second state, the electric lock central control function is not activated, and the mechanical unlocking function can be realized. Among them, the electric unlocking function is to drive the unlocking device to move by the electric opening device to realize the release of the door, and the mechanical unlocking is to release the door by applying an external force to the external opening device. The driving device is set to provide driving force for other devices in the electric lock. The driving device can rotate in a first direction and a second direction, and the first direction and the second direction are opposite, and the driving device is connected to the central control device. It can be understood that the driving device rotates in two opposite directions and can drive the central control device to move in two opposite directions, thereby realizing the switching of the central control device between the first state and the second state.

[0063] Furthermore, when the central control device is in the first state, the driving device rotates in the first direction to switch the central control device to the second state. In the above process, the electric opening device is in a non-working state. It can be understood that the electric unlocking function is not activated at this time and the electric unlocking function cannot be realized. After the driving device stops rotating in the first direction, the driving device can reset itself. At this time, the driving device rotates in the second direction and drives the electric opening device to move, thereby driving the electric opening device to switch from the non-working state to the working state.

[0064] Furthermore, the reset driving device rotates in the first direction again, thereby driving the electric opening device to realize the electric unlocking function.

[0065] In an embodiment of the present application, a driving device, an electric opening device, a central control device and an unlocking device are provided. The driving device rotates, resets and rotates again in a first direction. The two rotations in the first direction can respectively realize the switching of the central control device from a first state to a second state, as well as the electric unlocking function of the electric lock. In actual applications, it is avoided that the driving devices of the central control device and the electric opening device are integrated, so that the central control device directly opens the vehicle door while it is in motion.

[0066] Optionally, in an embodiment of the present application, when the central control device is in the second state, the driving device rotates in the second direction, driving the central control device to switch from the second state to the first state, and at the same time switches the electric opening device to a non-working state.

[0067] In an embodiment of the present application, when the central control device is in the second state, the driving device reverses, that is, rotates in the second direction, driving the central control device to switch from the second state to the first state. During the switching process, the electric opening device can be switched from the working state to the non-working state, thereby turning off the electric unlocking function and activating the central control unlocking function.

[0068] Optionally, in an embodiment of the present application, the electric lock also includes an external opening device, which is movably connected to the electric opening device. When the central control device is in the second state, the driving device rotates along the second direction, and can drive the external opening device to move through the central control device, so that the electric opening device moves to a non-working state.

[0069] In the embodiment of the present application, in actual application, the electric unlocking function is to release the door by driving the unlocking device through the electric opening device; the mechanical unlocking function is to release the door by applying an external force to the external opening device. It can be understood that when the electric opening device is in the working state, the driving device rotates in the second direction, and the driving device drives the external opening device to move through the central control device, and the external opening device drives the electric opening device to switch to the non-working state. At this time, the electric unlocking function is not activated.

[0070] Optionally, in an embodiment of the present application, the electric lock also includes an external opening device, which is movably connected to the unlocking device and the electric opening device respectively. When the central control device is in the second state, the external opening device can drive the unlocking device to release the vehicle door, while putting the electric opening device in a non-working state.

[0071] In the embodiment of the present application, in actual application, the electric unlocking function is to release the door by driving the unlocking device through the electric opening device; the mechanical unlocking function is to release the door by applying external force to the external opening device. In order to integrate the central control lock and electric unlocking functions into the electric lock, and to prevent the central control action from directly opening the door, the electric unlocking function and the mechanical unlocking function will not appear at the same time. Therefore, when the central control device is in the second state, the external opening device can drive the unlocking device to release the door.

[0073] In the embodiment of the present application, when the worm wheel 17 rotates in the first direction, the electric opening rocker arm 7 rotates with the rotation of the worm wheel 17. When the electric opening device is in the first state, the worm wheel 17 rotates in the first direction, the electric opening rocker arm 7 rotates accordingly, and the electric opening intermediate arm 9 is movably connected to the unlocking device. The worm wheel 17 rotates in the first direction again, the electric opening rocker arm 7 rotates accordingly, and the electric opening intermediate arm 9 moves with the rotation of the electric opening rocker arm 7, thereby causing the unlocking device to move, realizing the electric unlocking function of the electric lock, and then realizing the release of the vehicle door.

[0075] In the embodiment of the present application, the pawl 2 can be rotatably mounted on the housing of the electric lock through a pin, and the arc groove on the ratchet 1 can release the lock pin mounted on the vehicle body, thereby realizing the release of the door. The unlocking rocker arm 3 and the electric opening intermediate arm 9 are movably connected. Specifically, the unlocking rocker arm 3 and the electric opening intermediate arm 9 are axially connected. When the central control device is in the first state, the electric opening intermediate arm 9 rotates to drive the unlocking rocker arm 3 to move, thereby driving the pawl 2 and the ratchet 1 to eliminate the meshing, thereby realizing the release of the door.

[0076] Optionally, in an embodiment of the present application, the outward opening device includes an outward opening control rod 4, an outward opening connecting arm 5 and an outward opening connecting arm 5 axis.

The outward opening control rod 4 can slide relative to the outward opening connecting arm 5, and the outward opening control rod 4 and the unlocking rocker arm 3 are movably connected; wherein the driving device can rotate in the first direction and the second direction, and can drive the central control device to switch between the first state and the second state, and drive the outward opening control rod 4 to slide between the first position and the second position.

[0077] In the embodiment of the present application, the outward opening control lever 4 and the outward opening connecting arm 5 are connected by the outward opening connecting arm 5 axis rotation. When the worm gear 17 rotates in the first direction, the central control device switches from the second state to the first state, the outward opening control lever 4 moves from the second position to the first position, and the central control connecting rod 15 moves in the positive direction. When the worm gear 17 rotates in the first direction again, the electric opening rocker arm 7 rotates accordingly, and the electric opening intermediate arm 9 moves with the rotation of the electric opening rocker arm 7, thereby causing the unlocking device to move, realizing the electric unlocking function of the electric lock, and then realizing the release of the door. When the worm gear 17 rotates in the second direction, the central control device switches from the first state to the second state, and the outward opening control lever 4 moves from the first position to the second position.

[0078] Optionally, in an embodiment of the present application, the electric opening intermediate arm 9 includes a first fitting surface 9a, a second fitting surface 9b, a third fitting surface 9c and a fourth fitting surface 9d; when the central control device is in the first state, the first fitting surface 9a abuts against the electric opening rocker arm 7, and when the driving device rotates along the first direction, the second fitting surface 9b pushes the unlocking rocker arm 3 to rotate, thereby driving the pawl 2 to rotate and release the ratchet 1 to release the door; when the central control device is in the second state, the third fitting surface 9c is separated from the unlocking rocker arm 3, the fourth fitting surface 9d abuts against the external opening control rod 4, and the electric opening device is in a non-working state; when the central control device is in the first state, the fourth fitting surface 9d is separated from the external opening control rod 4, and the electric opening device can be in a working state.

The unlocking rocker arm 3 has a third limiting surface 3c. When the central control is in the central control locking position (i.e., the first state), and the electric opening rocker arm 7 rotates in the first direction under the action of the motor assembly, the second contact surface 9b on the electric opening intermediate arm 9 abuts against the third limiting surface 3c, pushing the unlocking rocker arm 3 to rotate synchronously in the first direction, and the second limiting surface 3b thereon contacts with the pawl 2, pushing the pawl 2 to rotate, thereby releasing the ratchet 1.

A first contact surface 18a is provided at the bottom of the worm wheel 17, and the first contact surface 18a and the electric open rocker arm 7 abut against each other. When the worm wheel 17 rotates in the second direction, the first contact surface 18a pushes the electric open rocker arm 7 to rotate counterclockwise along the rotation axis of the electric open rocker arm 7; a second contact surface 18b is provided at the upper part of the worm wheel 17. When the worm wheel 17 rotates in the first direction, the second contact surface 18b can contact the central control rocker arm 14 in the first state, and push the central control rocker arm 14 to rotate in the second direction, so that the central control device switches from the first state to the second state; a third contact surface 18c is provided at the upper part of the worm wheel 17. When the worm wheel 17 rotates in the second direction, the third contact surface 18c can contact the central control rocker arm 14 in the central control unlocking position, and push the central control rocker arm 14 to rotate in the first direction, so that the central control device switches from the second state to the first state.

[0082] Optionally, in an embodiment of the present application, the unlocking rocker arm 3 includes a first limiting surface 3a, a second limiting surface 3b and a third limiting surface 3c; when the central control device is in the second state, the first abutting surface 4a abuts against the first limiting surface 3a, the third limiting surface 3c abuts against the second fitting surface 9b, the second limiting surface 3b abuts against the pawl 2, and the unlocking rocker arm 3 can push the pawl 2 to rotate and release the ratchet 1; when the central control device is in the first state, the first abutting surface 4a abuts against the first limiting surface 3a, the third limiting surface 3c abuts against the second fitting surface 9b, the second limiting surface 3b abuts against the pawl 2, and the unlocking rocker arm 3 can rotate to push the pawl 2 to rotate and release the ratchet 1.

[0083] Furthermore, the electric open rocker arm 7 has a first mating surface 7a and a second mating surface 7b; when the central control device is in the first state, the first mating surface 9a and the second mating surface 7b abut against each other; when the central control device switches from the second state to the first state, the first mating surface 7a and the driving device abut against each other to make the electric open rocker arm 7 rotate in the second direction.

[0084] In the embodiment of the present application, when the central control device switches from the second state to the first state, if the door outer handle is pulled, the outer opening connecting arm 5 and the outer opening control rod 4 rotate in the first direction, and the first abutting surface 4a abuts against the first limiting surface 3a of the unlocking rocker arm 3, so that the unlocking rocker arm 3 rotates in the second direction, and then the pawl 2 is pushed away to release the ratchet 1 to open the door. At the same time, the fourth abutting surface 4d of the outer opening control rod 4 always abuts against the fourth fitting surface 9d of the electric opening intermediate arm 9, and the electric opening intermediate arm 9 is restrained in the non-working position.

[0085] The motor starts, driving the worm wheel 17 to rotate in the first direction, and the first contact surface 18a on the worm wheel 17 abuts against the first matching surface 7a on the electric opening rocker arm 7, so that the electric opening rocker arm 7 overcomes the force of its return spring and rotates in the second direction. The electric opening intermediate arm 9 connected to the electric opening rocker arm 7 is used to transfer the action of the electric opening rocker arm 7 to the unlocking rocker arm 3, which also rotates synchronously. However, since the fourth abutting surface 4d of the external opening control rod 4 always abuts against the fourth fitting surface 9d of the electric opening intermediate arm 9, the electric opening intermediate arm 9 remains in the non-working position.

[0086] The worm wheel 17 continues to rotate in the first direction, and when the third contact surface 18c on the worm wheel 17 abuts against the central control rocker arm 14, the central control rocker arm 14 is pushed to rotate in the second direction.

[0087] The central control rocker arm 14 rotates in the second direction to make the central control connecting rod 15 slide, and the central control connecting rod 15 abuts against the second abutting surface 4b on the outer opening control rod 4, pushing the outer opening control rod 4 to slide into the central control locking position (that is, the second state). The fourth abutting surface 4d on the outer opening control rod 4 no longer abuts against the fourth fitting surface 9d on the electric opening intermediate arm 9, but at this time the third fitting surface 9c on the electric opening intermediate arm 9 abuts against the unlocking rocker arm 3, and the electric opening intermediate arm 9 is still in the non-working position.

[0088] After the motor stops driving, the worm wheel 17 rotates in the second direction to reset to the middle position under the action of its reset spring 19, the electric opening rocker arm 7 rotates in the first direction to reset to the initial position under the action of its reset spring 19, and the electric opening intermediate arm 9 also rotates in the first direction synchronously. When the unlocking rocker arm 3 rotates to the fourth abutting surface 4d and disengages, the electric opening intermediate arm 9 rotates in the first direction to the first contact surface 9a and the first mating surface 7a under the action of the reset spring 19 of the electric opening intermediate arm 9. At this time, the electric opening intermediate arm 9 enters the working position, and the central control device is in the first state, and mechanical unlocking cannot be achieved.
