Description

Technical Field

[0001] The present invention relates to the technical field of automobile door locks, and in particular to an automobile side door lock. Background Art

[0002] Cars are a means of transportation that people often use in daily life. Cars are gradually becoming intelligent and electronic, making them more comfortable and convenient to use. The sense of experience has greatly increased, and the security of electronic information technology has been continuously enhanced. Electronically controlled door opening is a new type of car door lock with a simple and compact mechanical structure and good development prospects.

[0003] With consumers' demand for intelligent and convenient cars, the sealing effect of the whole vehicle has been greatly improved compared with before in order to improve the internal sound insulation effect. The sealing force has increased accordingly, and electric release side door locks have begun to be used in the market. Self-priming, electric opening and ice-breaking functions are the changes in the control methods of various components of car doors with the development of electronic technology, making the control of car doors more automated, ensuring personal safety, and increasing user experience and the convenience of opening and closing doors.

[0004] At present, when closing the door, the ratchet wheel rotates to a certain angle, and the pawl is locked by the spring to achieve the locking effect. In the cold winter, the car door and the door lock will freeze, and the car door is often frozen, so the ratchet wheel cannot return to its position naturally. At the same time, the sealing strip becomes hard and the sealing force increases; the door opening and closing are affected, sometimes the door cannot be closed, and sometimes the electric release cannot open the door.

[0005] The device that assists door opening and closing through a single pull wire is a mechanism for assisting door opening and closing, which can solve the regret that the door cannot be closed due to increased sealing force, and the door and door lock are frozen and cannot be released electrically; the assisted door opening is usually named ice breaking, and the assisted door closing is usually named self-priming.

[0006] At present, the common door lock structures that realize the door lock self-priming + ice-breaking function in the automotive industry are mainly the following:

[0007] 1) Self-priming, ice-breaking door lock + double-wire actuator

[0008] This type of door lock uses an actuator with dual pull-wire output. When the door is closed to half-locked, the self-priming pull-wire drives the door lock mechanical structure, pulling the door lock from the half-locked position to the fully locked position, and the door is fully closed. When ice breaking is required, the actuator's ice-breaking pull-wire drives the door lock's internal mechanical structure to open the door. This type of door lock realizes the self-priming and ice-breaking functions of the door lock, but requires a dual pull-wire actuator, which is more expensive.

[0009] 2) Self-priming door lock + single pull-wire actuator + electric auxiliary ice-breaking mechanism

[0010] The door lock can only cooperate with the actuator to complete the self-priming function, and does not have the ice-breaking function. An auxiliary mechanism is required to break the ice, which increases the space requirements for the door sheet metal, increases the complexity of the mechanism, and increases the cost.

[0011] 3) Self-priming door lock + single pull wire actuator

[0012] The door lock system is simple and can only achieve self-closing of the door lock. It does not have an ice-breaking function and cannot be adapted to models with electric doors.

[0013] The Chinese patent with publication number CN 115807592 A discloses an electric open car side door lock with self-priming function, including a lock body and a shell, an electric self-opening mechanism is arranged on the shell, and a self-priming mechanism and an ice-breaking mechanism are arranged on the lock body. When the door is automatically or manually closed to a semi-locked state, the ratchet and the pawl are first gear meshed, and the self-priming mechanism assists in realizing the self-priming function through the self-priming cable and related mechanisms when the door is not completely closed, and the ice-breaking mechanism assists in breaking ice and opening the door through the ice-breaking cable and related mechanisms when the door is not opened. However, the mechanism includes at least two cables and related operating connection structures, the structure is relatively complex, the system cost is high, and the installation requirements for the door are higher, which greatly increases the weight of the door.

[0014] Based on this, this application is specially filed. Summary of the invention

[0015] In view of this, the present invention aims to propose a vehicle side door lock to solve the problem of complex structure and high cost of the vehicle side door lock in the prior art for realizing auxiliary ice-breaking function and auxiliary self-priming function.

[0016] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0019] The self-priming ice-breaking auxiliary device comprises a rotating rod, an ice-breaking push rod and a self-priming push rod. The rotating rod can be pulled and rotated by a cable mechanism and reset when the cable mechanism is not working. The ice-breaking push rod and the self-priming push rod are hingedly arranged on the rotating rod.

[0020] In the auxiliary self-priming working condition, the rotating rod is pulled and rotated by the cable mechanism, the self-priming push rod is unlocked, and the self-priming push rod can push the first pushing part on the ratchet wheel, thereby driving the ratchet wheel to move, thereby realizing the locking of the ratchet wheel and the pawl;

[0021] Under the auxiliary ice-breaking condition, the rotating rod is pulled and rotated by the cable mechanism, and the self-priming interruption rod in the electric opening mechanism is displaced and pushed to the self-priming push rod. The rotation of the self-priming push rod is limited. During the rotation of the rotating rod, the ice-breaking push rod can push the second pushing part on the ratchet, thereby driving the ratchet to move, so that the ratchet and the pawl can be disengaged from the door.

[0022] Furthermore, the rotating rod is sleeved on the second rotating shaft, and a first torsion spring is arranged on the second rotating shaft, and the first torsion spring is used for resetting the rotating rod.

[0024] Furthermore, the self-priming push rod is hingedly connected to the rotating rod via a fourth rotating shaft, and a third torsion spring is arranged on the fourth rotating shaft. The third torsion spring can reset the self-priming push rod after the rotating rod is reset.

[0025] Furthermore, one end of the third torsion spring is connected to the rotating rod, and the third torsion spring can apply a force to the self-priming push rod to push the first pushing part to move when the rotating rod is pulled and rotated by the cable mechanism.

[0026] Furthermore, a first limit rod is provided on the ice-breaking push rod, and the first limit rod is used to limit the rotation position of the self-priming push rod relative to the ice-breaking push rod.

[0027] Furthermore, in the auxiliary ice-breaking condition, the rotating rod drives the ice-breaking push rod to move toward the ratchet during rotation, and the position of the first limit rod on the ice-breaking push rod changes. The self-priming push rod is restricted by the self-priming interruption rod, and the auxiliary self-priming condition fails.

[0028] Furthermore, under the auxiliary self-priming condition, when the pushing end of the self-priming push rod abuts against the first pushing part and rotates toward the ratchet wheel, the ice-breaking push rod moves in the direction away from the second pushing part under the action of the second torsion spring, and the auxiliary ice-breaking condition fails.

[0029] Furthermore, a second limit rod is provided on the self-priming push rod, the second limit rod is connected to one end of the third torsion spring, and in the auxiliary ice-breaking condition, the self-priming interruption rod abuts against the second limit rod.

[0030] Furthermore, the automobile side door lock of the present invention further comprises a door lock and an actuator, the housing of the door lock is formed by a base plate and a lock bracket, a ratchet and a pawl are rotatably arranged on the base plate of the door lock, and the automobile side door lock comprises an auxiliary self-priming function and an auxiliary ice-breaking function;

[0032] S11: When the door is in a semi-locked state, the internal signal switch of the side door lock is triggered, giving a signal to the whole vehicle, and the whole vehicle gives a signal to the actuator. The actuator rotates to pull the cable of the cable mechanism, and the auxiliary self-priming function of the self-priming ice-breaking auxiliary device is turned on. The self-priming push rod in the self-priming ice-breaking auxiliary device pushes the ratchet wheel to rotate forward to assist in closing the door;

[0033] S12: When the auxiliary self-priming function is executed, the ice-breaking push rod in the self-priming ice-breaking auxiliary device moves away from the ratchet wheel, and the ice-breaking function fails;

[0034] S13: When the ratchet reaches the fully locked position, the self-priming ends;

[0035] S14: Execute self-priming reset, and the self-priming ice-breaking auxiliary device returns to the initial state;

[0036] The auxiliary ice-breaking function includes the following steps:

[0037] S21: When the door is in a semi-locked state, the internal signal switch of the side door lock is triggered, giving a signal to the whole vehicle, and the whole vehicle gives a signal to the actuator. The actuator rotates to pull the cable of the cable mechanism, and the auxiliary ice-breaking function of the self-priming ice-breaking auxiliary device is turned on. The self-priming interruption rod in the electric opening mechanism is displaced and pushed to the self-priming push rod.

[0065] like Figures 1 to 13 As shown, the present invention discloses a vehicle side door lock, comprising:

[0066] The electric opening mechanism 200 includes a ratchet 5 and a pawl 7. The ratchet 5 and the pawl 7 are deformed to form a fully locked state, a half-locked state and an unlocked state according to their positions. A first pushing part 8 and a second pushing part 9 are provided on the ratchet 5.

[0067] The self-priming ice-breaking auxiliary device 100 comprises a rotating rod 1, an ice-breaking push rod 2, and a self-priming push rod 3. The rotating rod 1 can be pulled and rotated by a cable mechanism 4, and reset when the cable mechanism 4 is not working. The ice-breaking push rod 2 and the self-priming push rod 3 are hingedly arranged on the rotating rod 1.

[0068] In the auxiliary self-priming working condition, the rotating rod 1 is pulled and rotated by the cable mechanism 4, and the self-priming push rod 3 is unlocked. The self-priming push rod 3 can push the first pushing part 8 on the ratchet 5, thereby driving the ratchet 5 to move, so as to achieve the locking of the ratchet 5 and the pawl 7;

[0069] Under the auxiliary ice-breaking condition, the rotating rod 1 is pulled and rotated by the cable mechanism 4, and the self-priming interruption rod 17 in the electric opening mechanism 200 is displaced and pushed to the self-priming push rod 3. The rotation of the self-priming push rod 3 is limited. During the rotation of the rotating rod 1, the ice-breaking push rod 2 can push the second pushing part 9 on the ratchet 5, thereby driving the ratchet 5 to move, so that the ratchet 5 and the pawl 7 can be disengaged from the door.

[0070] The automobile side door lock described in the present invention, through the self-priming ice-breaking auxiliary device 100, includes a rotating rod 1 that can be pulled and rotated by a cable mechanism 4, and an ice-breaking push rod 2 and a self-priming push rod 3 hingedly connected to the rotating rod 1. In the initial state, the ice-breaking push rod 2 and the self-priming push rod 3 act as a whole under the action of a reset mechanism (such as a torsion spring) and a limiting structure. When the door is closed and is in a semi-locked state, a relevant electrical signal is given to the control module, and the control module gives a signal to the actuator. The actuator rotates and pulls the pull wire of the cable mechanism 4, and the pull wire pulls the rotating rod 1 inside the side door lock. At this time, the self-priming push rod 3 is unlocked, and the self-priming push rod 3 can rotate relative to the rotating rod 1 and abut against the first pushing portion 8 on the ratchet 5. The rotating rod 1 is During the rotation process, the self-priming push rod 3 can exert a force to push the first pushing part 8 to move, thereby pushing the ratchet 5 to rotate forward, thereby realizing auxiliary door closing; when the door is in a half-open state, the electric opening mechanism 200 starts to open the door. At the same time, due to the low temperature, the door is frozen and not opened. The side door lock gives a signal to the whole vehicle, and the whole vehicle gives a signal to the actuator. The actuator rotates to pull the pull wire of the cable mechanism 4, and the pull wire pulls the rotating rod 1 inside the side door lock. At this time, the self-priming interruption rod 17 in the electric opening mechanism 200 is displaced and pushed to the self-priming push rod 3. The movement of the self-priming push rod 3 is relatively restricted. During the rotation of the rotating rod 1, the ice-breaking push rod 2 pushes the second pushing part 9 on the ratchet 5 to drive the ratchet 5 to reverse, so that it turns to break ice and perform auxiliary door opening.

[0071] The automobile side door lock described in the present invention is provided with a cable mechanism 4 combined with an improved self-priming and ice-breaking auxiliary device 100. Under the auxiliary self-priming working conditions and the auxiliary ice-breaking working conditions, when the cable mechanism pulls the rotating rod 1 to move, the self-priming push rod 3 and the ice-breaking push rod 2 are respectively driven to push the ratchet 5 to rotate forward or reverse. The actuator can realize the self-priming or ice-breaking function through a single zipper. The structure is greatly optimized, at least one zipper device and the corresponding transmission structure are reduced, the product structure is optimized, the installation space is saved, the assembly efficiency of the product is improved, the production cost of the side door lock is greatly reduced, and the intelligent opening and closing of the vehicle door is realized.

[0072] As a preferred example of the present invention, the rotating rod 1 is sleeved on the second rotating shaft 10 , and a first torsion spring 18 is arranged on the second rotating shaft 10 . The first torsion spring 18 is used for resetting the rotating rod 1 .

[0073] The torsion spring is used to realize the rapid reset of the rotating rod 1 after the cable mechanism 4 loses its force, which has a simple structure, reliable operation and low cost.

[0074] As a preferred example of the present invention, the ice-breaking push rod 2 is hingedly connected to the rotating rod 1 via a third rotating shaft 11, and a second torsion spring 19 is arranged on the third rotating shaft 11, and the second torsion spring 19 is used for resetting the ice-breaking push rod 2 when it rotates relative to the rotating rod 1.

[0075] On the one hand, this arrangement ensures the reliability of the ice-breaking push rod 2 when assisting ice-breaking under the action of the rotating rod 1, and also enables the self-priming ice-breaking auxiliary device 100 to quickly reset after the auxiliary ice-breaking work is completed. It has a simple structure, is easy to assemble, and is reliable to use.

[0076] As a preferred example of the present invention, the self-priming push rod 3 is hingedly connected to the rotating rod 1 through a fourth rotating shaft 12, and a third torsion spring 20 is arranged on the fourth rotating shaft 12. The third torsion spring 20 is used to apply a force to the self-priming push rod 3 to push the first pushing part 8 to move when the rotating rod 1 is pulled and rotated by the cable mechanism 4, and can reset the self-priming push rod 3 after the rotating rod 1 is reset.

[0077] This arrangement further improves the reliability of the self-priming ice-breaking auxiliary device 100 in the auxiliary self-priming condition, in which the self-priming push rod 3 pushes the ratchet wheel 5 to rotate forward under the action of the rotating rod 1 to achieve self-priming.

[0078] As a preferred example of the present invention, a first limiting rod 13 is provided on the ice-breaking push rod 2 , and the first limiting rod 13 is used to limit the rotation position of the self-priming push rod 3 relative to the ice-breaking push rod 2 .

[0079] Under normal working conditions, the self-priming push rod 3 is fixed relative to the ice-breaking push rod 2 under the action of the first limit rod 13 and the third torsion spring 20. The first limit rod 13 is used to limit the self-priming push rod 3 from rotating in the direction of the driven end away from the first pushing part 8 toward the ratchet 5. In the auxiliary ice-breaking working condition, the electric opening mechanism 200 works to push the self-priming interruption rod 17 to move toward the side close to the self-priming ice-breaking auxiliary device 100, so that the self-priming interruption rod 17 abuts against the self-priming push rod 3, preventing the self-priming push rod 3 from abutting against the pushing end of the first pushing part 8 and rotating in the direction close to the ratchet 5. The rotating rod 1 is pulled to rotate by the cable mechanism 4. At this time, the rotating rod 1 rotates and the self-priming push rod 3 is limited by the self-priming interruption rod 17, the self-priming push rod 3 can only rotate with a very small displacement, and then it is abutted and limited by the self-priming interruption rod 17. The ice-breaking push rod 2 also rotates under the action of the second torsion spring 19, and the first limiting rod 13 is unlocked. The ice-breaking push rod 2 moves integrally with the second pushing portion 9 on the ratchet 5 under the action of the rotating rod 1. At this time, although the position of the first limiting rod 13 on the ice-breaking push rod 2 changes, since the self-priming push rod 3 is limited by the self-priming interruption rod 17, the self-priming push rod 3 is relatively stationary, thereby preventing the self-priming push rod 3 from contacting the first pushing portion 8 when the self-priming ice-breaking auxiliary device 100 performs the auxiliary ice-breaking function.

[0080] As a preferred example of the present invention, under the auxiliary self-priming working condition, when the self-priming push rod 3 abuts against the pushing end of the first pushing part 8 and rotates toward the ratchet 5, the ice-breaking push rod 2 rotates in the direction opposite to the rotation direction of the self-priming push rod 3 under the action of the second torsion spring 19.

[0081] This setting makes the auxiliary ice-breaking function of the self-priming auxiliary ice-breaking device 100 invalid when performing the auxiliary self-priming function, and can only perform self-priming to lock and close the door. This setting further improves the reliability of the self-priming auxiliary ice-breaking device 100 when performing the auxiliary self-priming function or the auxiliary ice-breaking function.

[0082] As a preferred example of the present invention, a second limit rod 16 is provided on the self-priming push rod 3 , the second limit rod 16 is connected to one end of the third torsion spring 20 , and in the auxiliary ice-breaking condition, the self-priming interruption rod 17 abuts against the second limit rod 16 .

[0083] This arrangement enables, under the auxiliary self-priming condition, the rotating rod 1 can generate a force applied to the second limit rod 16 through the third torsion spring 20 when rotating, so that the self-priming push rod 3 pushes the first pushing part 8 to drive the ratchet 5 to rotate forward to achieve full lock. Under the auxiliary ice-breaking condition, the second limit rod 16 can be reliably abutted by the self-priming interruption rod 17, preventing the self-priming push rod 3 from performing the auxiliary self-priming function.

[0084] This configuration further improves the reliability of the self-priming ice-breaking auxiliary device 100 in performing the auxiliary ice-breaking function and the auxiliary self-priming function.

[0085] As a preferred example of the present invention, the first pushing portion 8 and the second pushing portion 9 are two protrusions arranged on the ratchet 5. As an example of the present invention, the first pushing portion 8 and the second pushing portion 9 are two protruding structures arranged on the ratchet 5 away from the pawl 7, the pushing surface of the first pushing portion 8 close to the self-priming push rod 3 is arranged in an arc shape, and the pushing surface of the second pushing portion 9 close to the ice-breaking push rod 2 is also arranged in an arc shape.

[0086] This configuration further improves the reliability of the self-priming ice-breaking auxiliary device 100.

[0087] The vehicle side door lock described in the present invention includes a self-priming ice-breaking auxiliary device 100 and an electric opening mechanism 200. The electric opening mechanism 200 includes a ratchet 5 and a pawl 7. The ratchet 5 is hingedly connected to the housing through a first rotating shaft 6, and the pawl 7 is hingedly connected to the housing through a fifth rotating shaft 14. The first locking portion 501 on the ratchet 5 and the second locking portion 701 on the pawl 7 cooperate with each other to achieve switching of full locking, half locking or unlocking functions. When auxiliary ice-breaking function or auxiliary self-priming function is required, the ratchet 5 and the pawl 7 are in a semi-locked state, and a semi-locked gap 15 is formed between the first locking portion 501 of the ratchet 5 and the second locking portion 701 of the pawl 7. At this time, the ratchet 5 cannot respond naturally, resulting in the inability to fully open or fully lock the door lock.

[0088] When the door is in a semi-locked state, the internal signal switch of the side door lock is triggered, giving a signal to the whole vehicle, and the whole vehicle gives a signal to the actuator. The actuator rotates and pulls the pull wire of the cable mechanism 4, and the rotating rod 1 rotates clockwise, and the self-priming push rod 3 disengages from the limit mechanism and is unlocked (not shown in the figure). The self-priming push rod 3 rotates counterclockwise under the action of the third torsion spring 20, so that the end of the self-priming push rod 3 close to the first pushing part 8 abuts against the first pushing part 8. At this time, due to the rotation of the self-priming push rod 3, the first limit rod 13 on the ice-breaking push rod 2 is unlocked to a certain position, and the ice-breaking push rod 2 rotates counterclockwise under the action of the second torsion spring 19. At this time, when the rotating rod 1 is pulled to rotate by the cable mechanism 4, the auxiliary self-priming function starts to work, and the auxiliary ice-breaking function fails. When the ratchet 5 reaches the fully locked position, the self-priming ends; then the self-priming reset is performed, and under the action of the spring force, except for the ratchet 5, all others return to the initial position. When the door is in a semi-locked state, the side door lock gives a signal to the whole vehicle, and the whole vehicle gives a signal to the actuator. At this time, the self-priming interruption rod 17 in the electric opening mechanism 200 is displaced to abut against the second limit rod 16 on the self-priming push rod 3, and the actuator rotates to pull the pull wire of the cable mechanism 4, and the pull wire pulls the rotating rod 1 inside the side door lock, and the rotating rod 1 rotates clockwise. Under the limiting action of the self-priming interruption rod 17, the self-priming push rod 3 rotates a very small position counterclockwise under the action of the third torsion spring 20, and the first limit rod 13 on the ice-breaking push rod 2 rotates to unlock, and the ice-breaking push rod 2 also rotates a very small position counterclockwise. This motion structure is as shown in FIG. Fig. 9 As shown, the ice-breaking push rod 2 is disengaged from the limit mechanism and unlocked, and the ice-breaking push rod 2 moves integrally with the rotating rod 1 until the ice-breaking push rod 2 abuts against the second pushing portion 9 on the ratchet 5. In the process of the ice-breaking push rod 2 moving integrally with the rotating rod 1, the first limit rod 13 on the ice-breaking push rod 2 also moves a distance. During this process, the self-priming push rod 3 is abutted and limited by the self-priming interruption rod 17, and the self-priming push rod 3 is stationary, and the auxiliary self-priming function fails. As the cable mechanism 4 further pulls the rotating rod 1, the ice-breaking push rod 2 pushes the ratchet 5 to move outward, thereby realizing auxiliary ice-breaking door opening. When the door is opened, the ice-breaking is interrupted, and the rotating rod 1 is reset under the action of the spring force; after the door is opened, the controller receives the door opening signal and electrically resets it. At the same time, the self-priming interruption rod 17 is reset, and the ice-breaking push rod 2 and the self-priming push rod 3 are reset under the action of the spring force; except for the ratchet 5, all others return to their initial positions.

[0094] S14: Execute self-priming reset, and the self-priming ice-breaking auxiliary device 100 returns to the initial state;

[0095] The auxiliary ice-breaking function includes the following steps:

[0096] S21: When the door is in a semi-locked state, the internal signal switch of the side door lock is triggered, giving a signal to the whole vehicle, and the whole vehicle gives a signal to the actuator. The actuator rotates to pull the cable of the cable mechanism 4, and the auxiliary ice-breaking function of the self-priming ice-breaking auxiliary device 100 is turned on. The self-priming interruption rod 17 in the electric opening mechanism 200 is displaced and pushed to the self-priming push rod 3. The ice-breaking push rod 2 in the self-priming ice-breaking auxiliary device 100 pushes the ratchet 5 to reverse, and assists in closing and opening the door;

[0097] S22: When the auxiliary ice-breaking function is executed, the self-priming push rod 3 in the self-priming ice-breaking auxiliary device 100 is away from the ratchet wheel 5, and the auxiliary self-priming function fails;

[0098] S23: When the car door is opened, the auxiliary ice breaking function is interrupted;
