[0051] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] like Figure 1 , 210, the present invention proposes a main-auxiliary linkage type automobile door lock, which is arranged in a door lock housing and is used to unlock the main door lock and the auxiliary door lock; it includes a locking toggle plate 1, an inner and outer opening linkage plate 2, a transmission rod 3, a locking electric drive unit, a locking manual drive unit, a travel limiter 7, a ratchet opening toggle plate 11, an outer opening rocker arm 12, an inner opening toggle plate 13, an inner opening rocker arm 14, a locking rocker arm 15, and an auxiliary lock opening rocker arm 16.

[0053] As attached Figure 3 As shown, the locking toggle plate 1 is rotatably arranged around the first rotation center line a and switches between the locking position and the unlocking position; one side of the inside-outside opening linkage plate 2 is transmission-connected to one end of the locking toggle plate 1, and the other side thereof is used for transmission connection to the main lock of the vehicle door, and an inside-outside opening linkage rod 201 is arranged on one side surface of the inside-outside opening linkage plate 2, and the outside opening linkage rod 201 is parallel to the first rotation center line a; the transmission rod 3 is located on one side of the locking toggle plate 1, one end of the transmission rod 3 is connected to the inside-outside opening linkage rod 201, and the other end of the transmission rod 3 is used to connect the vehicle door auxiliary lock; wherein, when the locking toggle plate 1 switches from the locking position to the unlocking position, the inside-outside opening linkage plate 2 swings to one side and toggles the ratchet of the vehicle door main lock, so that the vehicle door main lock is unlocked, and at the same time, the transmission rod 3 is pulled to one side along with the inside-outside opening linkage plate 2, so that the vehicle door auxiliary lock is unlocked.

[0054] Specifically, in the attached Figure 3 In the embodiment, a first rotation axis A is provided at the first rotation center line a of the door lock housing, wherein the locking toggle plate 1 is sleeved on the first rotation axis A to achieve clockwise or counterclockwise rotation of the locking toggle plate 1;

[0055] The transmission connection relationship between the inner and outer opening linkage plate 2 and the locking toggle plate 1 is shown in the attached figure. Figure 6 As shown: a locking toggle step 103 is provided on the other side of the locking toggle plate 1, and an inner-outer opening linkage protrusion 202 is provided on one side of the inner-outer opening linkage plate 2, and the inner-outer opening linkage protrusion 202 abuts against the locking toggle step 103; specifically, the inner-outer opening linkage plate 2 is located on the side of the locking toggle plate 1, the locking toggle step 103 is provided on the side of the locking toggle plate 1, and the inner-outer opening linkage protrusion 202 is provided on one end of the side of the inner-outer opening linkage plate 2, and the inner-outer opening linkage protrusion 202 abuts against the locking toggle step 103, and the inner-outer opening linkage rod 201 is located on the other end of the rear side of the inner-outer opening linkage plate 2 and is parallel to the first rotation axis A, and the inner-outer opening linkage rod 201 extends to one side of the locking toggle plate 1;

[0056] The transmission rod 3 is located on one side of the locking toggle plate 1, and can be set in contact with the locking toggle plate 1 or separately from the locking toggle plate 1. One end of the transmission rod 3 has a hole and is sleeved on the inner and outer rod linkage rod 201. As the locking toggle plate 1 rotates, the locking toggle plate 1 drives the inner and outer opening linkage plate 2 to swing, and the inner and outer opening linkage plate 2 drives the transmission rod 3 to swing, thereby realizing the linkage between the main door lock and the auxiliary door lock of the car.

[0057] In this application, please refer to the attached Figure 3-5 The main door lock includes a pawl 9 and a ratchet 10; the pawl 9 is rotatably arranged around a second rotation center b, and one end of the pawl 9 is connected to an inner and outer opening linkage plate 2; the ratchet 10 is rotatably arranged around a first rotation center a, and can be locked with the pawl 9, and the first rotation center a is parallel to the second rotation center b; when the locking toggle plate 1 switches from a locked position to an unlocked position, the pawl 9 rotates around the second rotation center b to unlock or open the main door lock.

[0058] Specifically, in the attached Figure 3 In the embodiment, a second rotation axis B is arranged at a second rotation center b in the door lock housing, a pawl 9 is sleeved on the second rotation axis B, and a ratchet 10 is sleeved on the first rotation axis A. The shapes of the pawl 9 and the ratchet 10 and their unlocking and locking principles are disclosed in the prior art, so they will not be described in detail here.

[0059] In the attached Figure 5 It is not difficult to see that the side of the inner and outer opening linkage plate 2 is recessed to form a step, and the other end of the pawl 9 is provided with a pawl toggle rod 902, so under the action of the pawl torsion spring 901, the pawl 9 abuts against the step of the inner and outer opening linkage plate 2 through the pawl toggle rod 902;

[0060] When unlocking the main lock, the inner and outer opening linkage plate 2 presses down the pawl toggle rod 902, and the pawl toggle rod 902 always abuts against the step of the inner and outer opening linkage rod 2, so the pawl 9 rotates around the second rotation axis B and gradually disengages the ratchet wheel 10 to unlock the main lock of the vehicle door.

[0061] In summary, the linkage components for unlocking the main lock of the automobile door lock are: locking toggle plate 1-inside-outside opening linkage plate 2-ratchet pawl 9.

[0062] In this application, if attached Figure 1-3As shown, the auxiliary lock opening rocker arm 16 is located outside the door lock housing and is arranged to rotate around the first rotation center a, and is used to connect the opening pull line of the auxiliary lock of the vehicle door. An auxiliary lock opening protrusion 1601 is arranged on one side of the auxiliary lock opening rocker arm 16, and a transmission groove 301 is arranged on the transmission rod 3. The auxiliary lock opening protrusion 1601 extends into the transmission groove 301. When the locking toggle plate 1 switches between the unlocking position and the locking position, the transmission rod 3 drives the auxiliary lock opening rocker arm 16 to rotate around the first rotation center a through the transmission groove 301 and the auxiliary lock opening protrusion 1601;

[0063] Specifically, the auxiliary lock opening rocker arm 16 is located on the surface of the door lock shell, one end of which is sleeved on the first rotating axis A, and the other end of the auxiliary lock opening rocker arm 16 has a hole for connecting the opening pull wire for opening the auxiliary lock of the car door; through the cooperation of the transmission groove 301 and the auxiliary lock opening protrusion 1601, the transmission rod 3 hooks the auxiliary lock opening rocker arm 16 and pulls down the other end of it, completing the pulling action and achieving the purpose of unlocking the auxiliary lock.

[0064] See attached Figure 1 It can be seen that an arc groove is opened on the surface of the door lock shell, and the auxiliary lock opening protrusion 1601 passes through the arc groove. When the auxiliary lock opening rocker arm 16 rotates around the first rotation center a, the auxiliary lock opening protrusion 1601 slides in the arc groove, which can limit the movement trajectory of the auxiliary lock opening rocker arm 16.

[0065] Please see attached Figure 4 In order to facilitate the reset of the transmission rod 3 and the auxiliary lock opening rocker arm 16 after the main lock and the auxiliary lock body are unlocked, a transmission rod torsion spring 17 is provided between the locking toggle plate 1 and the transmission rod 3. When the locking toggle plate 1 is switched from the locked position to the unlocked position, the elastic force of the transmission rod torsion spring 17 is reduced, and when the locking toggle plate 1 is switched from the unlocked position to the locked position, the elastic force of the locking spring 17 is increased;

[0066] Specifically, a protrusion 302 is set on the side of the transmission rod 3 away from the locking toggle plate 1, and a protrusion 104 is set on the side of the locking toggle plate 1 close to the transmission rod 3. The locking spring 17 is sleeved on the protrusion 302, one end of which abuts against the side of the transmission rod 3, and the other end abuts against the protrusion 104. Therefore, when the inside-outside opening linkage plate 2 drives the transmission rod 3 to pull the auxiliary lock to open the rocker arm 16, the transmission rod 3 approaches the first rotation axis A (or the protrusion 104), and the elastic force of the locking spring 17 increases. The elastic force of the locking spring 17 helps to reset the inside-outside opening linkage plate 2 and the auxiliary lock to open the rocker arm 16.

[0067] In summary, the attached Figure 3The unlocking process of this application is described as follows: the locking toggle plate 1 rotates counterclockwise to press down the inner and outer opening linkage plate 2, the inner and outer opening linkage plate 2 rotates clockwise, the pawl 9 rotates counterclockwise, and the ratchet wheel 10 rotates counterclockwise - the main lock is unlocked; the inner and outer opening linkage plate 2 rotates counterclockwise to pull down the inner transmission rod 3, the auxiliary lock opening rocker arm 16 rotates counterclockwise, and pulls the auxiliary lock body to unlock;

[0068] Attach Figure 3 The locking process of this application is described based on the position relationship in the figure: the locking toggle plate 1 rotates counterclockwise, the transmission rod 3 is lifted up and reset, the auxiliary lock opening rocker arm 16 rotates clockwise and resets, and at the same time, the inner and outer opening linkage plate 2 rotates clockwise and resets, and the pawl 9 and ratchet 10 are reset.

[0069] Please see attached Figure 3-5 In order to realize the switching of the locking toggle plate 1 between the locking position and the unlocking position, the present application designs two power driving modes.

[0070] One of the driving modes is a locking electric drive unit, including a locking drive motor 4 and a locking transmission wheel 5. The outer edge of the locking dial plate 1 is provided with transmission teeth, and the output end of the locking drive motor 4 is provided with a worm 401, the worm 401 is meshed with the locking transmission wheel 5, the locking transmission wheel 5 rotates around its own axis, and the locking transmission wheel 5 is meshed with the transmission teeth on the locking dial plate 1;

[0071] For details, see the attached Figure 2 It can be seen that the external teeth on the locking transmission wheel 5 are divided into two parts, one part of the external teeth is meshed with the worm 401, and the other part of the external teeth is meshed with the external teeth on the locking toggle plate 1, and the tooth number ratio of one part of the external teeth meshed with the worm 401 and the other part of the external teeth meshed with the locking toggle plate 1 is greater than 1, thereby achieving a deceleration effect; the gear shaft 501 of the locking transmission wheel 5 is hidden inside the door lock housing and is parallel to the first rotation axis A, so that the locking transmission wheel 5 is meshed between the worm 401 and the locking toggle plate 1, and the transmission steering is realized by meshing the gears of the worm 401 and the locking transmission wheel 5, and the positions of the components in the door lock housing are further compacted.

[0072] In a specific embodiment, the locking drive motor 4 drives the worm 401 to rotate forward or reverse, thereby realizing the clockwise or counterclockwise rotation of the locking transmission wheel 5, and then realizing the clockwise or counterclockwise rotation of the locking dial plate 1.

[0073] See attached Figure 8It can be seen that another driving mode is a locking manual driving part, including a locking driving rod 6, one end of which rotates around the first rotation center line a, and the other end of which extends out of the door lock housing. A locking protrusion 101 is provided on the other side of the locking toggle plate 1. The locking driving rod 6 can abut against the locking protrusion 101 and drive the locking toggle plate 1 to switch from the locking position to the unlocking position through the locking protrusion 101.

[0074] In a specific embodiment, the locking drive rod 6 is sleeved on the first rotation axis A and its position is limited by a sleeve; Figure 8 The position in is used as a reference to describe the linkage relationship between the various components: when the locking toggle plate 1 rotates clockwise from the locking position to the unlocking position under the action of the locking electric drive unit, the locking protrusion 101 gradually leaves the locking drive rod 6, and the locking drive rod 6 does not participate in the electric drive process; when the locking toggle plate 1 rotates counterclockwise from the unlocking position to the locking position under the action of the locking electric drive unit, the locking protrusion 101 again abuts against the locking drive rod 6 to prepare for manual unlocking; when manual unlocking is required, the locking drive rod 6 is rotated clockwise, and the locking drive rod 6 drives the locking protrusion 101 to make the locking toggle plate 1 rotate clockwise to complete the unlocking action.

[0075] In this application, if attached Figure 5 As shown, the travel limiter 7 is located at the other side of the locking toggle plate 1, and a travel limiter protrusion 701 is provided on the travel limiter 7. A travel limiter groove 102 is provided on the outer edge of the locking toggle plate 1, and the travel limiter protrusion 701 moves in the travel limiter groove 102; when the locking toggle plate 1 switches between the locking position and the unlocking position, the travel limiter protrusion 701 contacts the groove walls at both ends of the travel limiter groove 102.

[0076] See attached Figure 7 and 8 It can be known that the position of the travel limiter 7 is fixed, and the locking toggle plate 1 is rotating; when the locking toggle plate 1 rotates to the limit, the travel limit protrusion 701 contacts the groove wall of the travel limit groove 102, achieving the purpose of travel limiting and avoiding the locking toggle plate 1 from over-travel operation and causing damage to components.

[0077] In a specific embodiment, the travel limiter 7 is a rubber member. The use of the rubber member can effectively reduce the rigid impact of the locking and sliding plate 1 and achieve limit buffering.

[0078] In this application, if attached Figure 3 and 4 As shown, the inner and outer opening linkage plate 2 is also connected to an outer opening torsion spring 8. When the locking toggle plate 1 switches from the unlocking position to the locking position, the elastic force of the outer opening torsion spring 8 increases. When the locking toggle plate 1 switches from the locking position to the unlocking position, the elastic force of the outer opening torsion spring 8 decreases.

[0079] Specifically reflected in the attached Figure 5 The outer opening torsion spring 8 is located on the side of the inner and outer opening linkage plate 2 away from the locking toggle plate 1, one end of the outer opening torsion spring 8 abuts against the side of the inner and outer opening linkage plate 2, and the other end of the outer opening torsion spring 8 abuts against the inner wall of the door lock housing to attach Figure 5 The position relationship in is used as a reference to describe the change in the elastic force of the outward opening torsion spring 8: when the inner and outer opening linkage plate 2 swings counterclockwise, the two ends of the outward opening torsion spring 8 approach each other and the elastic force increases, and this process is an unlocking process; when the inner and outer opening linkage plate 2 swings clockwise, the two ends of the outward opening torsion spring 8 move away from each other and the elastic force decreases, and this process is a locking process; the function of the outward opening torsion spring 8 is to help the inner and outer opening linkage plate 2 pull the auxiliary lock to open the rocker arm 16 and reset it.

[0080] In this application, in order to realize the external unlocking of the main lock, please refer to the attached Figure 1 , Attachment Figure 3-5 The pawl opening toggle plate 11 is rotatably arranged around a third rotation center c, and the pawl opening toggle plate 11 is sleeved on the inner and outer opening linkage rod 201, and the third rotation center c is parallel to the inner and outer opening linkage rod 201; the outer opening rocker arm 12 is rotatably arranged around the third rotation center c, and one end of the outer opening rocker arm 12 extends to the outside of the door lock housing; wherein, the outer opening rocker arm 12 abuts against one end of the pawl opening toggle plate 11, and the rotation of the outer opening rocker arm 12 can drive the pawl opening toggle plate 11, the inner and outer opening linkage plate 2, and the pawl 9 to work in linkage, so that the pawl 9 disengages the ratchet wheel 10.

[0081] Specifically, as attached Figure 4 and 5 As shown, a third rotation axis C is provided inside the door lock housing and at the third rotation center C, and the ratchet opening toggle plate 11 and the outward opening rocker arm 12 are respectively sleeved on the third rotation axis C; one end of the outward opening rocker arm 12 is bent toward the ratchet opening toggle plate 11 and provided with a ratchet opening toggle portion 1201, and the ratchet opening toggle portion 1201 will drive the ratchet opening toggle plate 11 to rotate around the third rotation axis C only when the main lock is unlocked and opened; an outward opening torsion spring 18 is provided inside the door lock housing, one end of the outward opening torsion spring 18 is fixed to the inner wall of the door lock housing, and the other end of the outward opening torsion spring 18 is fixed to the outward opening rocker arm 12, and the elastic force of the outward opening torsion spring 18 increases during the unlocking process of the main lock;

[0082] Attach Figure 4Taking the position relationship in as the reference, the unlocking process of the main lock for outward opening is: the outward opening rocker arm 12 rotates counterclockwise around the third rotation axis C, and the inner opening toggle plate 13 is driven to rotate counterclockwise around the third rotation axis C through the ratchet opening toggle part 1201, and the inner and outer opening linkage plate 2 is driven to rotate counterclockwise through the inner and outer opening linkage rod 201, and the inner and outer opening linkage plate 2 presses down the ratchet 9, and the main lock is unlocked; release the outward opening rocker arm 12, and the outward opening rocker arm 12 is reset under the action of the outward opening torsion spring 18, and the inner and outer opening linkage plate 2 is reset under the action of the outward opening torsion spring 8.

[0083] In this application, in order to omit the arrangement of the inner opening handle and the pull wire and reduce the usage and occupied space of the external parts of the door lock housing, please refer to the attached Figure 9-10 The inner opening toggle plate 13 is rotatably arranged around a fourth rotation center d, and the fourth rotation center d is perpendicular to the first rotation center a; the inner opening rocker arm 14 is rotatably arranged around the fourth rotation center d, and one end of the inner opening rocker arm 14 is rotatably connected to the inner opening toggle plate 13, and the inner opening toggle plate 13 can drive the inner opening rocker arm 14 to swing and toggle the ratchet pawl to open the toggle plate 11, so that the ratchet pawl 9 disengages the ratchet wheel 10.

[0084] Specifically, a fourth rotation axis D is arranged inside the door lock housing and at the fourth rotation center d, the inner opening toggle plate 13 is located outside the door lock housing, and an inner opening toggle protrusion 1301 is arranged on a side thereof close to the locking toggle plate 1; the inner opening rocker arm 14 is located inside the door lock housing, and an inner opening toggle groove matching the inner opening toggle protrusion 1301 is arranged on the side of the inner opening rocker arm 14, and an arc groove for the inner opening toggle protrusion 1301 to slide is arranged on the side of the door lock housing, so that when the inner opening toggle plate 13 rotates on the fourth rotation axis D, the inner opening rocker arm 14 is driven to rotate synchronously around the fourth rotation axis D, thereby completing a linkage action from outside the door lock housing to inside the door lock housing;
