Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1, an electric suction lock provided in an embodiment of the present application includes a driving module 10 and a lock body module 20. The electric suction lock body relates to an electric suction lock for a rear door of an automobile. Specifically, the automobile comprises an automobile body and an automobile tail door, wherein the automobile body is provided with a lock catch 50, and the lock body module 20 is arranged on the automobile tail door at a position corresponding to the lock catch 50. When the automobile tail door is closed, the lock body module 20 hooks the lock catch 50, and then the driving module 10 drives the lock body module 20 to lock, so that the automobile tail door can be effectively locked; when the automobile tail gate needs to be opened, the driving module 10 drives the lock body module 20 to unlock, the lock body module 20 is separated from the lock catch 50, and then the automobile tail gate can be opened manually or automatically through the electric stay bar.

Referring to fig. 2, the driving module 10 includes a driver 11, a transmission member 12 and an actuating member 13, the driver 11 is in transmission fit with the transmission member 12, the transmission member 12 is in transmission fit with the actuating member 13, and the driver 11 is configured to drive the transmission member 12 to rotate so as to drive the actuating member 13 to reciprocate along a predetermined path. Referring to fig. 5, the lock body module 20 includes a base plate 21, a lock tongue 22, a lock bar 23, a first toggle member 24 and a second toggle member 25, wherein the lock tongue 22, the lock bar 23, the first toggle member 24 and the second toggle member 25 are all rotatably mounted on the base plate 21 and all maintain a reset trend, that is, when an external force is applied, the above components (the lock tongue 22, the lock bar 23, the first toggle member 24 and the second toggle member 25) can rotate in a preset direction, and when the external force is removed, the components can be reset. Referring to fig. 1, fig. 3 and fig. 4, the first toggle member 24 is connected to the actuating member 13 through a first pull wire 30, and the first toggle member 24 can toggle the lock tongue 22 to move under the driving of the first pull wire 30, so that the lock tongue 22 is locked with the lock bar 23; the second toggle member 25 is connected with the actuator 13 through a second pull wire 40, and the second toggle member 25 can toggle the locking member 23 to move under the driving of the second pull wire 40, so that the locking member 23 and the lock tongue 22 are unlocked.

The electric suction lock is characterized in that the actuator 13 is respectively connected with a first pull wire 30 and a second pull wire 40, the first pull wire 30 is connected with the first toggle piece 24, the second pull wire 40 is connected with the second toggle piece 25, when the driver 11 drives the transmission piece 12 to rotate towards a first direction (for example, clockwise), the actuator 13 can be driven to move towards one side of a preset circuit, the first toggle piece 24 can be pulled, the first toggle piece 24 toggles the lock tongue 22, and the lock tongue 22 and the locking piece 23 can be locked; when the driver 11 drives the transmission member 12 to rotate in a second direction (e.g., counterclockwise), the actuator 13 is driven to move towards the other side of the predetermined circuit, and then the second toggle member 25 is pulled, and the second toggle member 25 toggles the locking member 23, so that the locking member 23 and the locking tongue 22 are unlocked. Therefore, the locking and unlocking actions can be controlled through one driver 11, the structure is simple, and the cost is low. And, the drive module 10 and the lock body module 20 are arranged for the components of a whole that can function independently, are connected through first acting line 30 and second acting line 40, compare in traditional integral type electricity and inhale the lock, can effectively reduce the volume of lock body module 20 for its installation space is unrestricted, can match different motorcycle types well, and the commonality is better.

Further, as shown in fig. 2, in the present embodiment, the actuating member 13 is a rod-shaped body extending along the rotation axis of the driving member 12, the driving member 12 is sleeved on the outer periphery of the actuating member 13 and is in transmission connection with the actuating member 13, the driving member 12 rotates to drive the actuating member 13 to perform linear reciprocating motion along the axial direction, and the first pulling wire 30 and the second pulling wire 40 are respectively connected to two ends of the actuating member 13. Specifically, the driver 11 drives the transmission member 12 to rotate, so as to drive the actuator 13 to perform reciprocating linear motion in the axial direction, for example, as shown in fig. 3, when the actuator 13 moves towards the left side, the first pull wire 30 can be pulled, the first toggle member 24 can be pulled through the first pull wire 30, and the lock tongue 22 is toggled through the first toggle member 24, so as to implement the locking action; when the actuator 13 moves to the right, the second pull wire 40 can be pulled, the second toggle member 25 can be pulled through the second pull wire 40, and the locking member 23 can be toggled through the second toggle member 25, so that the unlocking action is realized. The lengths of the first pulling wire 30 and the second pulling wire 40 can be set according to actual needs, and the first pulling wire 30 and the second pulling wire 40 can specifically adopt a rope body with certain strength, for example, a steel wire rope.

In addition, when the traditional electric suction lock breaks down after being locked, the traditional electric suction lock cannot be unlocked electrically or manually, and the automobile trunk can be opened only after the automobile tail door is damaged or the electric suction lock is removed. In order to solve the problem that the electric suction process is failed, which results in the incapability of electric or manual unlocking, further, in the embodiment, a non-self-locking transmission connection is adopted between the transmission member 12 and the execution member 13. The non-self-locking transmission connection means that the self-locking force (friction force) between the transmission member 12 and the actuating member 13 is small enough to easily generate relative movement when a certain external force is applied. Alternatively, the transmission member 12 and the actuating member 13 are connected by a non-self-locking screw drive, for example, a double-or multi-threaded screw drive, or a ball screw pair, which has a smaller self-locking force than a conventional rack-and-pinion structure or a cam mechanism.

Specifically, as shown in fig. 7, in the normal locking state, after the lock tongue 22 and the lock bar 23 are locked in place, both the first toggle member 24 and the second toggle member 25 are reset to the initial state, and at this time, the first toggle member 24 is in a position that does not interfere with the rotation of the lock tongue 22. As shown in fig. 8, in case of a failure, after the locking tongue 22 and the locking member 23 are locked in place, the first toggle member 24 and the second toggle member 25 cannot be reset to the initial state, and at this time, the first toggle member 24 is still in a position abutting against the locking tongue 22, so that even if the locking member 23 is toggled, the locking tongue 22 cannot be reset by reverse rotation due to the limitation of the first toggle member 24, and thus, electric unlocking cannot be achieved. And for the traditional electric suction lock, the driving module 10 can keep a self-locking state after completing driving, so that the first toggle piece 24 also keeps a locking state, at this time, even if the lock tongue 22 is manually rotated reversely, the first toggle piece 24 cannot be pushed to reset, and therefore manual unlocking cannot be realized. In this embodiment, after the above-mentioned failure as shown in fig. 8 occurs, the locking member 23 may be manually shifted to unlock the locking member 22, and then a certain pulling force is applied to the buckle 50, so that the buckle 50 drives the locking member 22 to rotate clockwise, and since the actuating member 13 and the transmission member 12 are in a non-self-locking state, the movement of the first shifting member 24 is not limited, so that the first shifting member 24 can be easily pushed to rotate and reset when the locking member 22 rotates, and finally, the unlocking is achieved.

Further, as shown in fig. 3, in the present embodiment, the actuating member 13 is a screw rod extending along the rotation axis of the transmission member 12, and the thread on the screw rod is a double-start or multi-start thread; the transmission member 12 includes a nut sleeve 121 engaged with the screw in a transmission manner, and a transmission portion provided on an outer peripheral surface of the nut sleeve 121 and engaged with the driver 11 in a transmission manner. The driver 11 acts on the transmission part to drive the nut sleeve 121 to rotate, and the nut sleeve 121 converts the rotation motion into the linear motion of the screw rod along the axial direction. In this way, the linear reciprocating motion of the screw can be realized by the forward rotation and the reverse rotation of the nut sleeve 121. The threads on the screw are double-start or multi-start threads, and correspondingly, the internal threads of the nut sleeve 121 are double-start or multi-start threads matched with the internal threads, so that compared with a single-start thread structure, the self-locking force of the double-start or multi-start threads is smaller, and manual unlocking can be realized more easily when a fault occurs.

Further, in the present embodiment, the transmission part is a transmission gear 122 disposed on the outer periphery of the nut sleeve 121, the driver 11 includes a power member 111, an output gear 112 connected to the output shaft of the power member 111, and a duplicate gear 113 disposed between the output gear 112 and the transmission gear 122, the output gear 112 is engaged with a first gear 1131 of the duplicate gear 113, and the transmission gear 122 is engaged with a second gear 1132 of the duplicate gear 113. Specifically, the output shaft of the power member 111 rotates to drive the output gear 112 to rotate, and then drives the first gear 1131 and the second gear 1132 to rotate, and drives the transmission gear 122 to rotate through the second gear 1132, thereby realizing the rotation of the nut sleeve 121. The transmission gear 122 and the nut sleeve 121 may be integrally formed nut gears, or may be separately assembled together by key connection or welding, so long as power transmission is achieved. The power member 111 may specifically be a driving motor. And a gear set is adopted between the power part 111 and the transmission part 12 for power transmission, so that the structure is simple, and the transmission is reliable. Specifically, the diameter of the first gear 1131 of the dual gear 113 is larger than that of the second gear 1132, and a speed change function can be realized. Optionally, the output gear 112, the duplicate gear 113 and the transmission gear 122 all adopt helical teeth, so that the transmission efficiency is higher.

Further, on the basis of the above embodiment, the driving module 10 further includes a base 14, the driver 11, the transmission member 12 and the actuator 13 are all mounted on the base 14, and two opposite ends of the transmission member 12 along the axial direction are respectively supported and limited by bearings 15. The driver 11, the transmission member 12 and the actuator 13 can be integrated into a whole through the base 14, so that the installation is convenient. The transmission piece 12 is supported and limited by the two bearings 15, and the concentricity of the transmission piece 12 and the execution piece 13 in the operation process can be ensured, so that the motion stability and the motion precision of the execution piece 13 are ensured.

Specifically, as shown in fig. 3, the driver 11 includes a power member 111, an output shaft of the power member 111 extends in a transverse direction, an output gear 112 is fixed on the output shaft of the power member 111, a duplicate gear 113 engaged with the output gear 112 is disposed at a front side of the output gear 112, the actuator 13 is a screw rod disposed at the front side of the power member 111 and extending in the transverse direction, and a space for the actuator 13 to move left and right is disposed on the base 14. The transmission member 12 includes a nut sleeve 121 sleeved on the screw rod, and a transmission gear 122 integrally formed on the periphery of the nut sleeve 121, the duplicate gear 113 is in meshing transmission with the transmission gear 122, opposite ends of the nut sleeve 121 are respectively rotatably mounted on the base 14 through bearings 15, and the axial displacement of the nut sleeve 121 can be limited through the bearings 15 at the two ends, so as to ensure concentricity in the operation process. The whole driving module 10 has a compact structure, occupies a small space, and is stable and reliable in power transmission.

Further, in this embodiment, one end of the actuator 13 is provided with a slider 16, the slider 16 is slidably engaged with the base 14, the first pull wire 30 or the second pull wire 40 is connected with the slider 16, the base 14 is further provided with two travel switches 17 arranged at intervals in the sliding direction of the slider 16, and the travel switches 17 are respectively in triggering engagement with the slider 16. The two travel switches 17 can control the movement travel of the slider 16, so that the movement travel of the actuator 13, the first pull wire 30 and the second pull wire 40 can be accurately controlled, and the position accuracy is ensured.

In addition, the driving module 10 further includes a cover 18, and a mounting cavity for accommodating the driver 11, the transmission member 12 and the actuator 13 is formed between the cover 18 and the base 14, so as to achieve good dustproof and waterproof effects.

Referring to fig. 5 to 7, based on the above embodiment, further, a lock slot 211 with an opening on one side is disposed on the base plate 21, a lock hook 221 for cooperating with the lock slot 211, a first stopping portion 222 and a second stopping portion 223 for cooperating with the locking member 23 are disposed on the periphery of the lock tongue 22, the lock body module 20 further includes a first trigger switch 26 and a second trigger switch 27 for electrically connecting with the driving module 10, the lock tongue 22 has a first trigger portion 224 for triggering and cooperating with the first trigger switch 26, and the locking member 23 has a second trigger portion 231 for triggering and cooperating with the second trigger switch 27.

Specifically, as shown in fig. 5, in the door opening state, the latch hook 221 of the latch tongue 22 is located at one side of the latch groove 211 without shielding the opening of the latch groove 211, and both the first trigger switch 26 and the second trigger switch 27 are kept in the non-triggered state. When the car tail-gate was closed, concrete accessible electric stay rod drove the car tail-gate and closes, overcome the sealed reaction force of car tail-gate through electric stay rod. When the lock module 20 contacts with the lock catch 50 on the vehicle body, the lock catch 50 can just push the lock tongue 22 inwards from the opening of the lock groove 211, so that the lock tongue 22 rotates counterclockwise, the lock hook 221 of the lock tongue 22 can hook the lock catch 50, meanwhile, the lock member 23 rotates counterclockwise under the action of the reset member 29 until the first stopping portion 222 of the lock tongue 22 is in locking fit with the lock member 23, and a half-locked state is achieved (as shown in fig. 6), at this time, the second trigger portion 231 triggers the second trigger switch 27, the second trigger switch 27 is turned on and can transmit a signal to the ECU, and then the driver 11 of the driving module 10 is controlled by the ECU to operate, so as to drive the first pull wire 30 and the first toggle member 24 to move. First toggle member 24 rotates clockwise to toggle lock tongue 22 to continue rotating counterclockwise until second stop portion 223 of lock tongue 22 is in locking fit with lock bar 23 to reach a full locking state (as shown in fig. 7), at this time, first trigger switch 26 and second trigger switch 27 are both in a triggered state and can transmit signals to an Electronic Control Unit (ECU) (electronic control unit), ECU controls driver 11 to rotate reversely to reset, and both first toggle member 24 and second toggle member 25 can reset through reset member 29. When receiving the unlocking signal, the driver 11 drives the actuator 13 to move, and drives the second pull wire 40 and the second toggle member 25 to move, and the second toggle member 25 rotates counterclockwise to toggle the locking member 23 to rotate clockwise, so that the locking member 23 is separated from the second blocking portion 223, and the unlocking is realized (as shown in fig. 9). After the unlocking is completed, the driver 11 drives the actuator 13 to reset, and the door is opened.

Further, referring to fig. 5, in the present embodiment, each of the first toggle member 24 and the second toggle member 25 includes a mounting portion, and a connecting rod 241 and a toggle rod 242 disposed on two opposite sides of the mounting portion, the substrate 21 is provided with a positioning pillar 28, the mounting portion is rotatably connected to the positioning pillar 28, the positioning pillar 28 is provided with a reset member 29 for maintaining a reset trend of the corresponding first toggle member 24 or the corresponding second toggle member 25, the connecting rod 241 is provided with a connecting hole 2411 for connecting with the corresponding first pull wire 30 or the corresponding second pull wire 40, and the toggle rod 242 is used for triggering and matching with the corresponding lock tongue 22 or the corresponding lock member 23. For example, as shown in fig. 5, the first toggle element 24 is rotatably mounted on the positioning column 28 through the mounting portion, the reset element 29 is a torsion spring sleeved on the positioning column 28, an end portion of the first pulling wire 30 is connected to the connecting hole 2411, and the first pulling wire 30 drives the connecting rod 241 to rotate, so as to drive the toggle rod 242 to rotate.

In the present embodiment, the first toggle member 24 and the second toggle member 25 adopt a lever mechanism, which can effectively reduce the driving force of the actuator 11 and reduce the output torque. For example, the force arm of the first toggle member 24 is the distance between the axial center of the positioning post 28 and the connection hole 2411, and the required suction force can be adjusted by adjusting the length of the force arm, so that the force and the reduction ratio of the driver 11 can be appropriately reduced. For example, during actual production, the first stirring part 24 and the second stirring part 25 with different arm of force lengths can be selected according to the suction force required by different vehicle types, so that when the suction force requirement is changed, the whole electric suction lock does not need to be replaced, and only the first stirring part 24 and the second stirring part 25 with corresponding arm of force need to be replaced, thereby effectively saving the cost and improving the universality of the electric suction lock.
