Description

Technical Field

[0001] The present invention relates to the field of automotive components, and more particularly to an integrated self - suction electric - opening side door lock with ice - breaking function. Background Art

[0002] The demand for automotive door locks in China is huge. There are various types of door locks in the market, and their structural designs are similar. Since an automotive door lock is a device used to lock the car door and achieve opening or locking through internally designed mechanical components, it has a safety protection function. It not only needs to ensure the reliable locking of the car door during normal driving but also prevent it from being opened smoothly in case of an accident. Therefore, an integrated product with sensitive operation, high safety, and compact structural design will be widely welcomed by the market. Summary of the Invention

[0003] The purpose of the present invention is to provide an integrated self - suction electric - opening side door lock with ice - breaking function, which can achieve the functions of integrated self - suction, electric - opening, and ice - breaking, and has a high product integration degree.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] The integrated self - suction electric - opening side door lock mainly consists of two side boxes for assembling transmission components and functional components. The functional components mainly include an opening arm, a detent pawl, a connecting arm, a suction arm, a clutch arm, an ice - breaking arm, and a clamping plate.

[0006] The opening arm and the detent pawl are coaxially arranged through a detent pawl shaft. One side edge of the detent pawl is buckled on the opening arm, so that when the opening arm rotates, it can push the detent pawl to rotate along the detent pawl shaft.

[0007] One end of the connecting arm is connected to the electric - suction secondary wheel of the transmission component, and the other end is movably connected to the middle part of the U - shaped suction arm. By moving the connecting arm, the suction arm is pulled to rotate along the clamping plate shaft.

[0008] The suction arm is connected to the clutch arm, and a clamping plate pin shaft provided on the clamping plate is inserted into an opening groove on the clutch arm. When the clamping plate pin shaft is stuck in the opening groove on the clutch arm, by rotating the clutch arm, the clamping plate is pushed to rotate in the locking direction.

[0009] An arc - shaped limiting groove is provided on the opening arm, and a limiting rod provided on the clutch arm is inserted into the arc - shaped limiting groove, so that the clutch arm and the opening arm are movably connected.

[0010] An ice - breaking shaft is provided in the middle of the ice - breaking arm. The ice - breaking shaft is on the rotation path of the suction arm. When the ice - breaking shaft is pushed by the rotation of the suction arm, one end of the connecting arm will abut against the lock pin. By pushing the ice - breaking arm to rotate along its rotation axis through the suction arm, the lock pin is pushed away from the groove on the clamping plate to achieve ice - breaking.

[0011] As a preferred technical solution of the present invention patent, the transmission component includes an electro-suction ice-breaking transmission assembly and an electro-opening transmission assembly, wherein:

[0012] The electro-suction ice-breaking transmission assembly includes an electro-suction motor, an electro-suction worm, an electro-suction turbine, and an electro-suction secondary wheel. The output shaft of the electro-suction motor is connected to the electro-suction worm, the electro-suction worm meshes with the electro-suction turbine, the electro-suction turbine meshes with the electro-suction secondary wheel to transmit power, and one end of the connecting arm is movably connected to the electro-suction secondary wheel through a shaft provided at a non-central position on the electro-suction secondary wheel;

[0013] The electro-opening transmission assembly includes an electro-opening motor, an electro-opening worm, an electro-opening turbine, and an electro-opening plate. The output shaft of the electro-opening motor is connected to the electro-opening worm, the electro-opening worm meshes with the electro-opening turbine, the electro-opening turbine and the electro-opening plate are coaxially arranged and rotate synchronously, and the electro-opening plate is in abutting connection with the opening arm. As the electro-opening plate rotates, the opening arm is subjected to a thrust force to rotate along the detent pawl shaft.

[0014] As a preferred technical solution of the present invention patent, after the acting force of the opening arm on the detent pawl is removed, the detent pawl is reset by a detent pawl compression spring.

[0015] As a preferred technical solution of the present invention patent, the rotation of the clamping plate in the unlocking direction is achieved by the torsion of the clamping plate torsion spring for energy storage.

[0016] As a preferred technical solution of the present invention patent, one end of the ice-breaking arm is assembled in the box body through an ice-breaking arm rotating shaft, and its end is reset by an ice-breaking arm tension spring when not under force.

[0017] Compared with the prior art, the beneficial effects of the present invention are manifested in:

[0018] 1. The electro-opening motor starts to work, transmits power through the electro-opening worm and the electro-opening turbine. The electro-opening turbine and the electro-opening plate rotate coaxially. Through the electro-opening plate, the opening arm together with the detent pawl rotates around the detent pawl shaft. The detent pawl disengages from the engagement point between it and the clamping plate. After the clamping plate is released from the limit, it can rotate in the unlocking direction under the action of the clamping plate torsion spring, creating a channel for the pin to withdraw, realizing electro-opening.

[0019] 2. After the electro-opening process is completed, the electro-suction motor starts to work, transmits power through the electro-suction worm, the electro-suction turbine, and the electro-suction secondary wheel. Since the connection position of one end of the connecting arm and the electro-suction secondary wheel is at a non-central position, as the electro-suction secondary wheel rotates, the other end of the connecting arm pushes the suction arm, and the suction arm continuously presses on the ice-breaking arm, forcing the ice-breaking arm to rotate along the ice-breaking arm rotating shaft, thereby pushing the locking pin away from the groove on the clamping plate to complete the ice-breaking process.

[0020] 3. After reaching the semi-locked state, the electric suction motor starts to work, transmitting power through the electric suction worm, electric suction turbine, and electric suction secondary wheel. Since one end of the connecting arm is connected to the electric suction secondary wheel at a non-central position, as the electric suction secondary wheel rotates, the other end of the connecting arm will pull the suction arm to rotate along the latch shaft. The suction arm is connected to the clutch arm. Through the rotation of the suction arm, the latch pin provided on the latch plate is inserted into the opening groove on the clutch arm. Through the rotation of the clutch arm, the latch plate is pushed to rotate in the locking direction until the suction process is completed.

[0021] 4. When a signal for electric opening is received before the suction process is completed, the electric opening motor starts to work, transmitting power through the electric opening worm and electric opening turbine. The electric opening turbine and the electric opening plate rotate coaxially. Through the electric opening plate, the opening arm and the stop claw rotate around the stop claw shaft, and the stop claw disengages from its meshing point with the latch plate. At the same time, the rotation of the opening arm drives the clutch arm to move, causing the opening groove on the clutch arm to disengage from the latch pin provided on the latch plate, so that the clutch arm cannot continue to drive the latch plate to rotate in the locking direction, thus realizing the function of priority opening during the locking process.

[0022] 5. This integrated self-suction electric opening with ice-breaking side door lock proposed by the present invention can be matched with various existing vehicle models, and can realize self-suction, electric opening, and ice-breaking functions. The suction and ice-breaking can be achieved by a single motor without the need to additionally increase the motor. The product has a high integration degree and sensitive operation.

Specific embodiments

[0032] Please refer to Figure 1-8 As shown, the present invention provides an integrated self - suction electric opening with ice - breaking side door lock, and its main body structure mainly includes two box bodies 1 for assembling transmission components and functional components. Based on Figure 7 From the perspective of the shown assembly structure, the transmission components at the upper right position of the side door lock are electric suction motor 6, electric suction worm 12, electric suction turbine 13, and electric suction secondary wheel 14. The output shaft of the electric suction motor 6 is connected to the electric suction worm 12, the electric suction worm 12 meshes with the electric suction turbine 13, the electric suction turbine 13 meshes with the electric suction secondary wheel 14 to transmit power, and one end of the electric suction secondary wheel 14 is movably connected to the connecting arm 16 through a shaft 15 arranged at a non - central position on the electric suction secondary wheel.

[0033] Based on Figure 7 From the perspective of the shown assembly structure, the transmission components at the upper left position of the side door lock are electric opening motor 5, electric opening worm 7, electric opening turbine 8, and electric opening disk 9. The output shaft of the electric opening motor 5 is connected to the electric opening worm 7, the electric opening worm 7 meshes with the electric opening turbine 8, the electric opening turbine 8 and the electric opening disk 9 are coaxially arranged and rotate synchronously, the electric opening disk 9 is in contact connection with the opening arm 10, and as the electric opening disk 9 rotates, the opening arm 10 is pushed to rotate along the stop claw shaft 24.

[0034] The functional components of this side door lock mainly consist of opening arm 10, stop claw 11, connecting arm 16, suction arm 17, clutch arm 20, ice - breaking arm 21, and clamping plate 22. The cooperation between the stop claw 11 and the clamping plate 22 can realize the closing and opening of the side door lock. When the side door lock is closed, the stop claw 11 and the clamping plate 22 are in contact through the meshing point 30 between them. Without the rotation of the stop claw 11, the clamping plate 22 cannot rotate along the clamping plate shaft 18 in the unlocking rotation direction. At this time, the locking pin 19 assembled and fixed on the vehicle body is firmly locked by the groove on the clamping plate 22, and the side door cannot be opened.

[0035] Please refer to together Figure 9, the opening arm 10 and the detent 11 are coaxially arranged through the detent shaft 24 and can both rotate along the detent shaft 24. At the same time, one side edge of the detent 11 is buckled on the opening arm 10, so that when the opening arm 10 rotates, it can push the detent 11 to rotate along the detent shaft 24. After removing the acting force of the opening arm 10 on the detent 11, the detent 11 is reset by the detent compression spring 25.

[0036] Please refer to Figure 10 , 11 , one end of the connecting arm 16 is connected to the electro-suction secondary wheel 14, and the other end is movably connected to the middle part of the U-shaped suction arm 17. By moving the connecting arm 16, the suction arm 17 is pulled to rotate along the clamping plate shaft 18. The suction arm 17 is connected to the clutch arm 20, and the clamping plate pin shaft 29 provided on the clamping plate 22 is snapped into the opening groove on the clutch arm 20. When the clamping plate pin shaft 29 is stuck in the opening groove on the clutch arm 20, by rotating the clutch arm 20, the clamping plate 22 is pushed to rotate in the locking direction. The rotation of the clamping plate 22 in the unlocking direction is achieved by the torsion of the clamping plate torsion spring 26. An arc-shaped limiting groove 2 is provided on the opening arm 10, and a limiting rod (not shown in the figure, assembled in a preset mounting hole on the clutch arm 20) provided on the clutch arm 20 is inserted into the arc-shaped limiting groove 2, so that the clutch arm 20 is movably connected to the opening arm 10.

[0037] One end of the ice-breaking arm 21 is assembled in the box body through the ice-breaking arm rotating shaft 28, and its end is reset by the ice-breaking arm pulling spring 27 when not under force. At this time, the ice-breaking arm 21 does not contact the lock pin 19. An ice-breaking shaft 23 is provided in the middle of the ice-breaking arm 21, and the ice-breaking shaft 23 is on the rotation path of the suction arm 17. When the ice-breaking shaft 23 is pushed by the rotation of the suction arm 17, one end of the connecting arm 16 will abut against the lock pin 19. The rotation of the suction arm 17 is pulled by the connecting arm 16. When the electro-suction secondary wheel 14 rotates until the critical position, the pushing displacement of the suction arm 17 on the ice-breaking arm 21 reaches the maximum. The purpose of pushing the ice-breaking arm 21 to rotate along its rotation shaft by the suction arm 17 is to push the lock pin 19 away from the groove on the clamping plate 22. Because the lock pin remains stationary in the vehicle body, the side door lock is separated from the vehicle body, that is, the side door is opened. When the phenomenon that the side door cannot be opened due to icing or other reasons occurs, this lock ice-breaking structure can quickly open the side door.

[0038] The working process of this integrated self-suction electric-opening side door lock with ice-breaking proposed by the present invention is mainly as follows:

[0039] Electrical opening process: The electrical opening motor 5 starts to work, transmits power through the electrical opening worm 7 and the electrical opening turbine 8. The electrical opening turbine 8 and the electrical opening disk 9 rotate coaxially. Through the electrical opening disk 9, the opening arm 10 together with the stop claw 11 rotates around the stop claw shaft 24. The stop claw 11 disengages from the engagement point 30 between it and the clamping plate 22. After the clamping plate 22 is released from the limit, it can rotate in the unlocking direction under the action of the clamping plate torsion spring 26, creating a passage for the pin shaft 19 to withdraw. When there is no ice formation or other situations, the side door can be opened at this time. However, when ice formation occurs, it is difficult to open the side door. At this time, the designed ice-breaking structure will come into play (even when there is no ice formation, this ice-breaking action is still executed).

[0040] Ice-breaking process: After the electrical opening process is completed, the electrical suction motor 6 starts to work, transmits power through the electrical suction worm 12, the electrical suction turbine 13, and the electrical suction secondary wheel 14. Since one end of the connecting arm 16 is connected to the electrical suction secondary wheel at a non-central position, as the electrical suction secondary wheel 14 rotates, the other end of the connecting arm 16 pushes the suction arm 17. The suction arm 17 continuously presses on the ice-breaking arm 21, forcing the ice-breaking arm 21 to rotate along the ice-breaking arm rotation shaft 28, thereby pushing the locking pin 19 away from the groove on the clamping plate 22 to complete the ice-breaking process.

[0041] Suction process: After manually or electrically operating to the semi-locked state, the electrical suction motor 6 starts to work, transmits power through the electrical suction worm 12, the electrical suction turbine 13, and the electrical suction secondary wheel 14. Since one end of the connecting arm 16 is connected to the electrical suction secondary wheel at a non-central position, as the electrical suction secondary wheel 14 rotates, the other end of the connecting arm 16 will pull the suction arm 17 to rotate along the clamping plate shaft 18. The suction arm 17 is connected to the clutch arm 20. Through the rotation of the suction arm 17, the clamping plate pin 29 provided on the clamping plate 22 is inserted into the opening groove on the clutch arm 20. Through the rotation of the clutch arm 20, the clamping plate 22 is pushed to rotate in the locking direction until the suction process is completed.

[0042] It should be noted that when the connecting arm 16 rotates the electrical suction secondary wheel 1.5 turns, it pulls the suction arm 17 to drive the rotation of the clutch arm 20. At this time, the clamping plate pin 29 provided on the clamping plate 22 is inserted into the opening groove on the clutch arm 20, thereby realizing the rotation of the clamping plate 22 in the locking direction. At the same time, the connecting arm 16 will not exert a thrust on the ice-breaking arm 21 during this process (suction process). When the connecting arm 16 rotates the electrical suction secondary wheel 1.5 turns in the other direction, its function is to push the ice-breaking arm 21 to realize the ice-breaking process. At this time, the clamping plate pin 29 provided on the clamping plate 22 disengages from the opening groove on the clutch arm 20, so the rotation of the clutch arm 20 will not drive the clamping plate 22 to rotate in the locking direction.

[0043] Opening priority during the suction process: When a signal for electric opening is received before the suction process is completed, the electric opening motor 5 starts to work, and the power is transmitted through the electric opening worm 7 and the electric opening turbine 8. The electric opening turbine 8 and the electric opening disk 9 rotate coaxially. Through the electric opening disk 9, the opening arm 10 and the stop claw 11 rotate around the stop claw shaft 24, and the stop claw 11 disengages from the engagement point 30 between it and the clamping plate 22. At the same time, the rotation of the opening arm 10 drives the movement of the clutch arm 20, causing the opening slot on the clutch arm 20 to disengage from the clamping plate pin shaft 29 provided on the clamping plate 22. Therefore, the clutch arm 20 cannot continue to drive the clamping plate 22 to rotate in the locking direction, and the function of opening priority during the locking process can be achieved.

[0044] The above content is only an example and illustration of the concept of the present invention. Those skilled in the art of the present technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution. As long as they do not deviate from the concept of the invention or exceed the scope defined by this claim book, they should fall within the protection scope of the present invention.
