Description

Technical Field

[0001] This invention relates to the field of automotive side door locks, and in particular to a structure for unlocking a car in the event of a collision using a shared electric release motor. Background Technology

[0002] With rapid societal development, automobiles have become widely used in people's lives and work. Vehicle safety has always been a crucial concern for consumers. In the event of a collision, the ability of the car doors to automatically unlock in a timely manner is vital for the escape of passengers.

[0003] Many car models on the market now feature automatic door locking and concealed door handles. To enhance vehicle safety, the automatic door locking function is usually triggered when the vehicle speed exceeds a certain value, and drivers also manually lock the car for safety. While the vehicle is in motion, the door locks are typically locked. If the doors cannot be unlocked in time during a collision, it will greatly hinder rescue efforts and pose a serious threat to the lives of the occupants. Summary of the Invention

[0004] The present invention proposes a structure for unlocking a car in the event of a collision using a shared electric release motor, which solves the above-mentioned problems existing in the prior art.

[0005] The technical solution of this invention is implemented as follows: A structure for unlocking a car in the event of a collision using a shared electric release motor is characterized by comprising a housing part, a locking block part, an electric opening mechanism, and a central locking unlocking mechanism. The housing includes a lower housing, a mounting plate, and an upper housing. The lower housing and the mounting plate are riveted together by a ratchet rotating shaft and a pawl rotating shaft, and the upper housing and the lower housing are connected together by screws. The locking block includes a ratchet rotating shaft, a pawl rotating shaft, a ratchet, and a pawl. The ratchet is mounted on the ratchet rotating shaft and rotates around it. The pawl is mounted on the pawl rotating shaft and rotates around it. One end of the pawl has a pawl boss on its upper part and this end contacts the external coupling rod. The other end of the pawl contacts the electric switching connecting rod. The electric opening mechanism includes an electric opening drive unit, a worm gear, an electric opening gear rotating shaft, an electric opening gear, an electric opening connecting rod, an electric opening connecting rod rotating shaft, and a neutral spring. The electric opening gear rotating shaft is installed on the upper housing, and the electric opening gear is installed on the electric opening gear rotating shaft and rotates around it. The electric opening gear has an electric opening gear boss on its upper housing and a boss on its back with a neutral spring installed on it. The electric opening drive unit is installed inside the upper housing, and the worm gear at its front end meshes with the electric opening gear. The electric opening connecting rod rotating shaft is installed on the mounting plate, and the electric opening connecting rod is installed on the electric opening connecting rod rotating shaft and rotates around it. One end of the electric opening connecting rod is attached to the electric opening gear boss of the electric opening gear, and the other end is attached to the tail of the ratchet pawl. The central locking unlocking mechanism includes a central locking link, an emergency lever, a control locking transmission rod, a control locking link, a control locking link spring, an outward opening coupling rod, an outward opening auxiliary rod, and an outward opening coupling rod spring. One end of the outward opening coupling rod is hinged to the outward opening auxiliary rod, and the other end has a guide post at the top and a first protruding rib at the bottom. The outward opening coupling rod spring is assembled on the outward opening coupling rod. The central locking link is installed on the lower housing, with a second protruding rib at the bottom that contacts the guide post of the outward opening coupling rod. The central locking link has a groove. The emergency lever is installed on the upper housing and rotates around the mounting axis. One end of the emergency lever is inserted into the groove of the central locking link to achieve linkage. The control locking transmission rod is installed on the rotating shaft of the electric locking gear and rotates around it. It has a first surface feature, a second surface feature, and a third surface feature. The control locking link is installed on the emergency lever, and the control locking link spring is assembled on the control locking link so that the arc of the head of the control locking link is always in close contact with the control locking transmission rod.

[0006] Preferably, the center spring can reset the electric open gear to its initial position after forward or reverse rotation, and the boss on the back of the electric open gear can push the control locking transmission rod to rotate when rotating.

[0007] Preferably, the elastic force of the spring of the outward-opening coupling rod can keep the guide post of the outward-opening coupling rod in close contact with the central control link. The central control link pushes the outward-opening coupling rod to rotate through the second protruding rib, so that the first protruding rib of the outward-opening coupling rod is disengaged or in contact with the pawl boss of the pawl, thereby realizing the central control locking or unlocking.

[0008] Preferably, when the electric opening drive unit drives the electric opening gear to rotate in the first direction, the electric opening gear pushes the electric opening linkage to rotate through the electric opening gear boss, and the electric opening linkage pushes the pawl to rotate and disengage from the ratchet, thereby realizing the electric opening of the door; at the same time, the boss of the electric opening gear contacts the first surface feature of the control locking transmission rod and pushes it to rotate, and the third surface feature of the control locking transmission rod pushes the control locking linkage, so that the head arc of the control locking linkage disengages from the movement trajectory of the boss of the electric opening gear.

[0009] Preferably, after the door is electrically opened, the electric opening drive unit receives a reset signal and drives the electric opening gear to rotate in a second direction opposite to the first direction. The boss of the electric opening gear contacts and pushes the third surface feature of the control locking transmission rod, so that the control locking transmission rod is reset to the initial position. Under the action of the control locking link spring, the control locking link re-adheres to the second surface feature of the control locking transmission rod. After the electric opening drive unit stops driving, the electric opening gear is reset to the initial position under the action of the center spring. During this process, the central locking link and the emergency lever remain stationary, and the central locking system remains locked.

[0010] Preferably, when the vehicle receives a collision signal, the electric unlocking gear rotates in the second direction, and the boss on its back contacts and pushes the control locking linkage to move. The control locking linkage pushes the emergency lever to rotate, and the emergency lever drives the central locking linkage to rotate to the unlock position. Under the action of the spring force of the external opening coupling rod, its first protruding rib contacts the pawl boss of the pawl, realizing the central locking unlock. After unlocking, the electric unlocking gear returns to the initial position under the action of the middle position spring.

[0011] Preferably, when the electric opening operation is performed after the central locking is unlocked, the electric opening drive unit drives the electric opening gear to rotate in the first direction to realize the electric opening of the door. At the same time, the boss of the electric opening gear pushes the control locking transmission rod to rotate. The third surface feature of the control locking transmission rod pushes the control locking link so that its head arc overlaps with the third surface feature. During the rotation of the control locking transmission rod, it contacts and pushes the emergency lever to rotate. The emergency lever drives the central locking link to rotate to the locked position. The central locking link pushes the outward opening coupling rod to rotate, so that the first protruding rib of the outward opening coupling rod disengages from the pawl boss of the pawl, completing the electric opening and locking after collision unlocking. Subsequently, the electric opening gear returns to the initial position according to the reset steps of the claims.

[0012] Preferably, the electric opening drive unit is an electric release motor, which realizes the electric opening of the door, mechanism reset and collision unlocking functions by reversing forward and reverse, respectively, replacing the traditional dual motor structure that realizes electric release and collision unlocking separately.

[0013] This invention discloses a structure for unlocking vehicles in the event of a collision using a shared electric release motor. Compared to existing automotive side door lock technology, this invention achieves functional reuse of the electric release motor through innovative design of the transmission mechanism, resulting in significant optimizations in terms of structure, cost, performance, and adaptability. Specific beneficial effects are as follows: 1. This invention abandons the traditional design of configuring separate motors for electric release and collision unlocking functions. By coordinating the forward and reverse rotation of a single electric release motor with the coordinated action of multiple sets of transmission links, it simultaneously realizes multiple functions such as electric door opening, mechanism reset, automatic collision unlocking, and reset and lock after unlocking. This significantly reduces the number of parts in the door lock mechanism, simplifies the overall transmission structure, makes the internal layout of the door lock more compact, and effectively improves the level of integrated design of automotive side door locks.

[0014] 2. The single-motor design directly reduces the procurement and manufacturing costs of motor components. At the same time, the reduced number of components lowers the complexity of the door lock mechanism assembly process, improves the assembly efficiency of the production line, and further saves manufacturing costs. In addition, the simplified transmission structure reduces the number of moving pairs, lowers the probability of wear during the mechanism's operation, and reduces the frequency and cost of later maintenance and repair, thus taking into account cost control on both the production and user ends.

[0015] 3. This invention, through the rational configuration of elastic components such as the center spring, the control locking linkage spring, and the outward coupling rod spring, achieves automatic reset of key components such as the electric opening gear and the control locking linkage. Combined with the precise engagement and linkage design between the transmission rod and the linkage, each step of the action, including electric opening, collision unlocking, and reset locking, can be precisely triggered and completed in an orderly manner. At the same time, it reduces the number of independent motors and transmission mechanisms, lowers the risk of malfunctions caused by multi-component linkage, improves the overall operational stability and reliability of the door lock mechanism, and ensures the effective triggering of safety functions such as collision unlocking.

[0016] 4. The compact integrated structure significantly reduces the overall size of the car side door lock, eliminating the need to reserve separate installation and movement space for two independent motors. This makes it more suitable for the narrow and complex installation environment inside car doors, providing more leeway for the layout of other components inside the door, and aligning with the industry trend of lightweighting and miniaturization of automotive components.

[0017] 5. In this invention, when the electric door opening operation is performed during normal vehicle driving, the motor drive only completes the door opening action and mechanism reset, without touching the emergency lever and central locking linkage, and always maintains the central locking state, avoiding accidental switching of the door lock central locking state during normal use; the motor will only trigger the collision unlocking action when the vehicle receives a collision signal, realizing a precise distinction between normal use functions and emergency safety functions, ensuring the door lock locking security during driving, and not affecting the daily electric opening user experience.

[0018] 6. Based on the automatic unlocking due to collision, this invention designs an electric unlocking and locking reset mechanism after unlocking. When the central control unit is unlocked due to a collision, only one normal electric opening operation is required to automatically lock the central control unit through motor drive linkage, allowing the door lock mechanism to quickly return to its initial state of normal use without additional manual reset operation, thus improving the practicality of the door lock mechanism and the convenience of subsequent use.

[0019] In summary, this invention achieves multiple goals of structural simplification, cost reduction, and performance improvement while ensuring the effective implementation of core functions such as electric opening of the car side door lock and collision unlocking. At the same time, it meets the development needs of automotive parts integration and lightweighting, and has high practical value and industry promotion value. Attached Figure Description

[0030] The following will refer to the appendices in the embodiments of the present invention. Figure 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0031] like Figure 1-10 As shown, this embodiment discloses a design scheme including a housing part, a locking block part, an electric opening mechanism, and a central locking unlocking mechanism.

[0032] 1) The housing part includes: lower housing 1, mounting plate 2, and upper housing 3. The lower housing 1 and mounting plate 2 are riveted together by ratchet rotating shaft 10 and pawl rotating shaft 12; the upper housing 3 is connected to the lower housing 1 by screws.

[0033] 2) The locking block includes: a ratchet rotating shaft 11, a pawl rotating shaft 12, a ratchet 10, and a pawl 13. The ratchet 10 is mounted on the ratchet rotating shaft 11 and rotates around the shaft. The pawl 13 is mounted on the pawl rotating shaft 12 and rotates around the shaft. One end of the pawl has a pawl boss 1301 on its upper part, which contacts the outwardly opening coupling rod 16, and the other end contacts the electrically opening connecting rod 8.

[0034] 3) The electric opening mechanism includes: an electric opening drive unit 4, with a worm gear 5 at its front end, an electric opening gear rotating shaft 7, an electric opening gear 6, an electric opening connecting rod 8, and an electric opening connecting rod rotating shaft 9; the electric opening gear rotating shaft 7 is mounted on the upper housing 3, the electric opening gear 6 is mounted on the gear rotating shaft 7 and rotates around the shaft, and has an electric opening gear boss 601 on it; the electric opening drive unit 4 is mounted in the upper housing 3, and the electric opening drive unit 4 meshes with the electric opening gear 6 through the front end worm gear 5; the electric opening connecting rod rotating shaft 9 is mounted on the mounting plate 2, and the electric opening connecting rod... The lever 8 is mounted on the rotating shaft 9 of the electric opening linkage and rotates around the mounting shaft. One end of the electric opening linkage 8 is attached to the electric opening gear boss 601 of the electric opening gear 6 and can be pushed by the electric opening gear 6. The other end is attached to the tail of the pawl 13. When the electric opening linkage 8 rotates, it can push the pawl 13 to rotate together. The electric opening gear 6 is equipped with a center spring 22 on its back, which can allow the electric opening gear 6 to return to the initial position after rotating forward or backward. There is a boss 602 on its back, which can push the control locking transmission rod 19 to rotate when rotating.

[0035] 4) The central locking unlocking mechanism includes: central locking link 17, emergency lever 18, control locking link 20, control locking link spring 21, control locking transmission rod 19, outward opening coupling rod 16, outward opening auxiliary rod 14, and outward opening coupling rod spring 15. One end of the outward-opening coupling rod 16 is hinged to the outward-opening auxiliary rod 14, and the other end has a guide post 1602 at the top and a first protruding rib 1601 at the bottom. A spring 15 is installed on the outward-opening coupling rod 16, so that under the action of the spring force, the upper guide post 1602 of the coupling rod 16 is always in close contact with the central control link 17. The central control link 17 is installed on the lower housing 1, and has a second protruding rib 1702 at the bottom, which contacts the upper guide post 1602 of the outward-opening coupling rod 16. This can push the outward-opening coupling rod 16 to rotate, so that the lower first protruding rib 1601 of the outward-opening coupling rod 16 is either disengaged or in contact with the upper pawl boss 1301 of the pawl 13, thus realizing the locking and unlocking of the central control. The central control link 17 has a groove 1701. The emergency lever 18 is mounted on the upper housing 3 and can rotate around the mounting shaft. The control locking transmission rod 19 is mounted on the electric gear rotating shaft 7 and rotates around the shaft. One end of the emergency lever 18 is inserted into the groove 1701 of the central control link 17, so that the two are linked together. The control locking link 20 is mounted on the emergency lever 18 and is equipped with a control locking link spring 21, so that under the action of the spring force, the arc 2001 of the head of the control locking link 20 is always in close contact with the control locking transmission rod 19. The control locking transmission rod 19 has a first surface feature 1901, a second surface feature 1902, and a third surface feature 1903.

[0036] The collision unlocking and electric locking actions are implemented as follows: 1. Initial state: such as Figure 5 and Figure 6 As shown, the door lock central control is in the locked state, that is, the locking linkage 17 pushes open the outward coupling rod 16, so that the lower first protruding rib 1601 of the outward coupling rod 16 is disengaged from the upper pawl boss 1301 of the pawl 13; the electric opening gear 6 is in the initial position under the action of the middle position spring 22; the control locking linkage 20 is in close contact with the second surface feature 1902 of the middle section of the control locking transmission rod 19 at the head arc 2001.

[0037] 2. Power-on function: The power-on drive unit 4 is started, such as... Figure 2 As shown in the view, the electric door opener 6 rotates in one direction, which in turn pushes the electric door opener linkage 8 to rotate via the electric door opener 601. The electric door opener linkage 8 then pushes the pawl 13 to rotate and disengage from the ratchet, thereby opening the car door. At this time, as... Figure 5As shown in the view, the electrically operated gear 6 rotates in direction two. When the boss 602 of the electrically operated gear 6 rotates, it contacts the first surface feature 1901 of the control locking transmission rod 19, pushing the control locking transmission rod 19 to rotate together. While the control locking transmission rod 19 rotates in direction two, the third surface feature 1903 pushes the control locking linkage 20, causing the head arc 2001 of the control locking linkage 20 to disengage from the trajectory of the boss 602 on the electrically operated gear and remain in its current position. Figure 7 Furthermore, throughout the entire process, because the central control is locked, the locking transmission rod 19 will not contact the emergency lever 18. 3. Electrically operated switch reset: When the electrically operated switch gear rotates to... Figure 7 When the door is in the correct position, the electric opening is completed. At this time, the door lock provides a reset signal, and the electric opening drive unit 4 starts to drive the electric opening gear to rotate in the reverse direction (direction one). During the rotation of the boss 602 of the electric opening gear, it will contact the third surface feature 1903 segment of the push control locking transmission rod 19, pushing the control locking transmission rod 19 to the initial position. Under the spring force of the control locking link spring 21, the control locking link 20 is in close contact with the second surface feature 1902 segment of the control locking transmission rod 19, such as... Figure 8 The state shown is as indicated. At this time, the electric switch drive unit ends its operation, and the electric switch gear returns to its original position under the action of the neutral spring. Figure 5 The initial position is shown. At this point, throughout the entire process, the central locking linkage 17 and the emergency stop lever 18 do not move, and the central locking system remains locked. Subsequently, during normal vehicle use, each time the door is opened electrically, the electric opening gear 6 will not contact the emergency stop lever 18, and the central locking status will not change.

[0038] 4. Collision Unlock: When a collision occurs, the vehicle will provide a collision signal. At this time, if... Figure 5 The electrically operated gear 6 will rotate in the specified direction. At this time, the boss 602 of the electrically operated gear 6 will contact the control locking linkage 20, pushing the control locking linkage 20 to move. The control locking linkage 20 pushes the emergency lever 18 to rotate, and the emergency lever 18 drives the central control linkage 17 to rotate to the unlock position. At this time, under the action of the spring force, the lower feature first protrusion rib 1601 of the outward-opening coupling rod 16 re-contacts with the upper pawl boss 1301 of the pawl 13, realizing central control unlocking. Figure 4 After unlocking, the electrically operated gear 6 returns to its initial position under the action of the neutral reset spring 22, ending the collision unlocking action. Figure 9 .

[0039] Collision unlock recovery: When the central locking system unlocks and then attempts to power-lock again, as described in step 2, the power-lock drive unit 4 drives the power-lock gear 6 to rotate. This rotation, via the power-lock gear boss 601, pushes the power-lock linkage 8 to rotate. The power-lock linkage 8 then pushes the pawl 13 to rotate and disengage from the ratchet, thereby opening the door and achieving power-locking. On the other hand, as... Figure 9As shown in the view, when the electric unlocking gear 6 rotates in direction two to perform the electric unlocking, the boss 602 of the electric unlocking gear 6 will contact the first surface feature 1901 of the control locking transmission rod 19 during rotation, pushing the control locking transmission rod 19 to rotate together. During the rotation of the control locking transmission rod 19 in direction two, its third surface feature 1903 will push the control locking linkage 20, causing the head arc 2001 of the control locking linkage 20 to disengage from the trajectory of the boss 602 on the electric unlocking gear, engage with the third surface feature 1903 of the control locking transmission rod 19, and remain in the current position. Since the central locking system is in the unlocked state at this time, the control locking transmission rod 19, during its rotation in direction two, will contact and push the emergency lever 18 to rotate, as... Figure 10 The emergency lever 18 pushes the central control linkage 17 to rotate to the locked position. The central control linkage 17 pushes the outward coupling lever 16 to rotate, so that the lower feature first protrusion rib 1601 of the outward coupling lever 16 disengages from the upper pawl boss 1301 of the pawl 13, thus achieving locking. After locking, the electric unlocking gear performs the reset action in step 3 and returns to the initial position. Thus, the electric unlocking and locking process after collision unlocking is completed.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

After unlocking, the electric unlocking gear (6) is reset to the initial position under the action of the middle position spring (22).

7. The structure for unlocking a vehicle in a collision using a shared electric release motor as described in claim 6, characterized in that, When the electric opening operation is performed after the central control is unlocked, the electric opening drive unit (4) drives the electric opening gear (6) to rotate in the first direction to realize the electric opening of the door. At the same time, the boss (602) of the electric opening gear (6) pushes the control locking transmission rod (19) to rotate. The third surface feature (1903) of the control locking transmission rod (19) pushes the control locking link (20) so that its head arc (2001) overlaps with the third surface feature (1903). During the rotation of the control locking transmission rod (19), it contacts and pushes the emergency lever (18) to rotate. The emergency lever (18) drives the central control link (17) to rotate to the locked position. The central control link (17) pushes the external opening coupling rod (16) to rotate, so that the first protruding rib (1601) of the external opening coupling rod (16) disengages from the pawl boss (1301) of the pawl (13), and completes the electric opening and locking after the collision unlocking. Subsequently, the electric opening gear (6) returns to the initial position according to the reset step of claim 5.

8. The structure for unlocking a vehicle in a collision using a shared electric release motor as described in claim 1, characterized in that, The electric opening drive unit (4) is an electric release motor. The motor realizes the electric opening of the door, mechanism reset and collision unlocking functions by reversing forward and reverse, respectively, replacing the traditional dual motor structure that realizes electric release and collision unlocking respectively.
