[0039] The outer shell forms a reliable support structure, which is conducive to connecting other components and provides protection. It also facilitates connection with car doors and is relatively easy to assemble.

[0040] The electric drive component moves, causing the locking linkage arm assembly to rotate. The locking linkage arm assembly then moves the sliding arm to the unlocked position, thus achieving electric unlocking.

[0041] After the electric unlocking is completed, the outward opening component is activated, which moves the sliding arm to a new position. The sliding arm then moves the pawl component around the second axis as the rotation center. The pawl component disengages from the ratchet component, and the ratchet component rotates, thus realizing the function of opening the door outward.

[0042] After electric unlocking, the inner opening component moves, causing a partial movement of the outer opening component. The outer opening component moves the sliding arm in conjunction with the sliding arm, which in turn moves the pawl component around the second axis. The pawl component disengages from the ratchet component, and the ratchet component rotates, thus enabling the inner opening of the door.

[0043] This overcomes the technical problems of poor linkage, functional failure, and safety hazards, achieving a relatively smooth linkage, reducing the probability of functional failure, and providing a relatively safe technical effect, thus proving its practicality. Attached Figure Description

[0049] To make the content easier to understand, the following detailed description is provided with reference to specific embodiments and accompanying drawings;

[0050] A new type of automotive side door lock solves the technical problem of poor linkage, which can lead to functional failures and safety hazards in related technologies. It can be manufactured and used, achieving relatively smooth linkage, reducing the probability of functional failures, and providing relative safety. The overall concept is as follows:

[0051] Implementation

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; a side door lock for automobiles, comprising:

[0053] 10 outer casings;

[0054] The electric drive unit 20 is connected to the housing 10;

[0055] The first shaft 30 is connected to the outer casing 10;

[0056] The second shaft 40 is connected to the outer casing 10 and is spaced apart from the first shaft 30.

[0057] The locking linkage arm assembly 50 is partially connected to one end of the first shaft 30 and the other part is disposed on one end of the second shaft 40, connected to the outer shell 10, and the locking linkage arm assembly 50 is rotated by the electric drive component 20.

[0058] The ratchet assembly 60 is connected to the other end of the first shaft 30, connected to the housing 10, and disposed opposite to the locking linkage arm assembly 50;

[0059] A pawl assembly 70 is movably connected to the other end of the second shaft 40 for contacting the ratchet assembly 60;

[0060] The sliding arm 80 is linked by the locking linkage arm assembly 50 and moves along the outer shell 10 to reach the unlocked position;

[0061] An outward-opening component 90 is connected to the outer casing 10 and to the sliding arm 80. It is used to move the sliding arm 80 in conjunction with the sliding arm 80. The sliding arm 80 is linked to the pawl assembly 70 to rotate around the second axis 40 as the rotation center. The pawl assembly 70 disengages from the ratchet assembly 60.

[0062] And an inner opening component 100, connected to the outer shell 10, is arranged perpendicularly to the outer opening component 90 and is used to actuate a partial movement of the outer opening component 90, wherein the outer opening component 90 moves in conjunction with the sliding arm 80.

[0063] Specifically, during implementation, the outer shell 10 forms a reliable support structure, which is conducive to connecting other components and provides protection. It is also conducive to connecting with the car door, and the assembly is relatively convenient.

[0064] When the electric drive component 20 is activated, it drives the locking linkage arm assembly 50 to rotate. The locking linkage arm assembly 50 then moves the sliding arm 80 to the unlocked position, thus achieving electric unlocking.

[0065] After electric unlocking, the outward opening component 90 moves, which in turn moves the sliding arm 80 to a new position. The sliding arm 80 then rotates the pawl component 70 around the second axis 40 as the rotation center. The pawl component 70 disengages from the ratchet component 60, and the ratchet component 60 rotates, thus realizing the outward opening door function.

[0066] After electric unlocking, the inner opening component 100 is activated, which triggers a partial movement of the outer opening component 90. The outer opening component 90 moves in conjunction with the sliding arm 80, which in turn moves the pawl component 70 around the second axis 40. The pawl component 70 disengages from the ratchet component 60, and the ratchet component 60 rotates, thus realizing the inner opening door function.

[0067] The linkage is relatively smooth, reducing the chance of functional failure and making it relatively safe;

[0068] Another implementation method:

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in implementation, the outer casing 10 includes: a main casing 10-1, connecting the electric drive unit 20, the first shaft 30, the second shaft 40, the locking linkage arm assembly 50, the ratchet assembly 60, the pawl assembly 70, the sliding arm 80, and the outward opening assembly 90; an upper cover 10-2, connected to one side of the main casing 10-1, covering the electric drive unit 20, the first shaft 30, the second shaft 40, the locking linkage arm assembly 50, the sliding arm 80, and the outward opening assembly 90, and the upper cover 10-2 is connected to the inward opening assembly 100; a lower cover 10-3, connected to the other side of the main casing 10-1, covering the ratchet assembly 60 and the pawl assembly 70; and a side cover 10-4, connected to the side wall of the upper cover 10-2, covering the inward opening assembly 100;

[0070] The main housing 10-1 is made of plastic; the upper cover 10-2 is also made of plastic and is connected to the main housing 10-1 by screws; the lower cover 10-3 is made of stainless steel and is connected to the main housing 10-1 by screws, and the lower cover 10-3 has an opening 10-31, which facilitates the insertion of latches on the car body (for example, the latch is a U-shaped structure, which is common knowledge), and engages with the ratchet 60-1 through the opening 10-31; the side cover 10-4 is made of plastic and is connected to the upper cover 10-2 by screws.

[0071] The main housing 10-1, upper cover 10-2, lower cover 10-3 and side cover 10-4 are separately arranged, which is conducive to the assembly of other components, the assembly is relatively convenient, and it also forms protection and is also conducive to the connection with the car door.

[0072] The electric drive component 20 includes: a motor 20-1 connected to the main housing 10-1; and a worm gear 20-2 connected to the drive shaft of the motor 20-1 and meshing with the locking linkage arm assembly 50.

[0073] Motor 20-1 is a commonly used structure in the prior art, used to generate rotational driving force. After receiving the electrical signal of unlocking the car key, motor 20-1 is activated, which in turn drives worm gear 20-2 to rotate. Those skilled in the art can directly and without doubt know how to set up motor 20-1 after seeing the disclosed content, without needing to put in creative effort or conduct excessive experiments.

[0074] The worm gear 20-2 is a commonly used structure in the prior art. It is connected to the drive shaft of the motor 20-1 and is used to lock the rotation of the linkage arm 50-1.

[0075] Among them, the first shaft 30 is a stepped shaft that is inserted into the main housing 10-1;

[0076] Among them, the second shaft 40 is a stepped shaft that is inserted into the main housing 10-1;

[0077] The locking linkage arm assembly 50 includes: a locking linkage arm 50-1, which is movably connected to one end of the first shaft 30 and meshes with the worm gear 20-2; and a first torsion spring 50-2, which is sleeved on one end of the second shaft 40 and connected between the locking linkage arm 50-1 and the main housing 10-1.

[0078] The locking linkage arm 50-1 is sleeved on the first shaft 30. It has a toothed part 50-11 on its outer circle. The toothed part 50-11 meshes with the worm gear 20-2. It also has a first arc-shaped groove 50-12 at one end. The first arc-shaped groove 50-12 is used to set one end of the sliding arm 80. It is in clearance fit with one end of the sliding arm 80, which is beneficial for the locking linkage arm 50-1 to move the sliding arm 80.

[0079] The first torsion spring 50-2 is a commonly used structure in the prior art. It is sleeved on the second shaft 40. One pin is connected to the locking linkage arm 50-1, and the other pin is connected to the main housing 10-1. When the locking linkage arm 50-1 rotates, it generates force, which makes the rotation of the locking linkage arm 50-1 relatively smooth and also helps the locking linkage arm 50-1 return to its original position.

[0080] The sliding arm 80 has an arc-shaped block structure, with one end set at the first arc-shaped groove 50-12 and the other end having a columnar protrusion 80-1. The columnar protrusion 80-1 is used to insert into the through groove 90-21 on the outward-opening linkage plate 90-2, and the columnar protrusion 80-1 extends out of the through groove 90-21 and is set in the second arc-shaped groove 90-41 on the outward-opening rocker arm 90-4, which is beneficial for the outward-opening rocker arm 90-4 to move the sliding arm 80 and the outward-opening linkage plate 90-2.

[0081] When motor 20-1 is activated, the worm gear 20-2 rotates, which in turn drives locking linkage arm 50-1 to rotate around the first shaft 30. Locking linkage arm 50-1 then moves sliding arm 80 to the unlocked position. (The unlocked position is explained as follows: Since pawl linkage shaft 70-2 is located at the bottom of sliding arm 80, as sliding arm 80 moves, its position gradually changes relative to pawl linkage shaft 70-2. Pawl linkage shaft 70-2 follows the third arc-shaped groove at the bottom of sliding arm 80, approaching the edge of sliding arm 80. At this point, pawl linkage shaft 70-2 is not fully protruding from the third arc-shaped groove, preparing for the action of outward opening component 90 or inward opening component 100.) This achieves electric unlocking, preparing for outward / inward opening of the car door.

[0082] Another implementation method:

[0083] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in implementation, the ratchet assembly 60 includes: a ratchet 60-1, movably connected to the other end of the first shaft 30; and a second torsion spring 60-2, sleeved on the other end of the first shaft 30, connecting the ratchet 60-1 and the main housing 10-1;

[0084] Ratchet 60-1 rotates around the first shaft 30 as its rotation center, contacting or separating from pawl 70-1. When in contact, the locking groove 60-11 on ratchet 60-1 engages with the latch on the car body. When separated, ratchet 60-1 rotates under the action of the second torsion spring 60-2. As the car door is opened, the car door gradually moves away from the latch on the car body, and ratchet 60-1 gradually releases the latch, thus opening the car door. When the car door is closed, the latch can drive ratchet 60-1 to rotate in the opposite direction, and the second torsion spring 60-2 stores force until the car door is closed in place. At this time, ratchet 60-1 contacts pawl 70-1, and ratchet 60-1 is limited by pawl 70-1, thus locking the car door.

[0085] The second torsion spring 60-2 is a common structure in the prior art. One pin is connected to the ratchet 60-1, and the other pin is connected to the main housing 10-1. It is used to generate torque, which is beneficial to the rotation of the ratchet 60-1.

[0086] The pawl assembly 70 includes: a pawl 70-1, one end of which is movably connected to the second shaft 40, the pawl 70-1 being used to contact the ratchet 60-1; and a pawl linkage shaft 70-2, connected to the other end of the pawl linkage shaft 70-2, being used to contact the sliding arm 80.

[0087] The pawl 70-1 is roughly an arc-shaped block structure with a groove 70-11 on the side wall. The groove 70-11 helps to limit the ratchet 60-1, and the contact reliability is relatively good.

[0088] The pawl linkage shaft 70-2 is a stepped shaft. One end is riveted to the pawl 70-1, and the other end is slidably connected to the third arc-shaped groove on the sliding arm 80. As the sliding arm 80 moves, the sliding arm 80 and the pawl linkage shaft 70-2 change positions. The pawl linkage shaft 70-2 follows the third arc-shaped groove at the bottom of the sliding arm 80 and approaches the edge of the sliding arm 80. At this time, the pawl linkage shaft 70-2 does not protrude completely out of the third arc-shaped groove, and the sliding arm 80 can contact and link the pawl linkage shaft 70-2 to move.

[0089] The outward-opening assembly 90 includes: an outward-opening rocker arm shaft 90-1 connected to the main housing 10-1; an outward-opening linkage plate 90-2 movably connected to the outward-opening rocker arm shaft 90-1 and connected to the sliding arm 80; a third torsion spring 90-3 sleeved on the outward-opening rocker arm shaft 90-1, disposed at the bottom of the outward-opening linkage plate 90-2, and connected between the outward-opening linkage plate 90-2 and the main housing 10-1; and an outward-opening rocker arm 90-4, one end of which is movably connected to the outward-opening rocker arm shaft 90-1 for moving the sliding arm 80 and the outward-opening linkage plate 90-2.

[0090] The outward-opening rocker arm shaft 90-1 is a stepped shaft;

[0091] The outward-opening linkage plate 90-2 is an arc-shaped plate structure. One end is movably connected to the outward-opening rocker arm shaft 90-1, and the other end is inserted into the sliding arm 80 through the through groove 90-21.

[0092] The third torsion spring 90-3 is a common structure in the prior art. One pin is connected to the outward opening linkage plate 90-2, and the other pin is connected to the main housing 10-1. It is used to generate torque, which is beneficial to the return of the outward opening linkage plate 90-2. When the outward opening linkage plate 90-2 returns, the outward opening linkage plate 90-2 is linked to the sliding arm 80 to return, and the sliding arm 80 is linked to the pawl assembly 70 to return.

[0093] The outward-opening rocker arm 90-4 has a waist-shaped block structure. One end is movably connected to the outward-opening rocker arm shaft 90-1. The bottom has a second arc-shaped groove 90-41. The second arc-shaped groove 90-41 contacts the columnar protrusion 80-1 on the sliding arm 80, which is conducive to the movement of the sliding arm 80 and the outward-opening linkage plate 90-2 through the outward-opening rocker arm 90-4.

[0094] Another implementation method:

[0095] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in implementation, the inner opening assembly 100 includes: an inner opening rocker arm shaft 100-1, connected to the upper cover 10-2; an inner opening rocker arm 100-2, movably connected to the inner opening rocker arm shaft 100-1; a contact block 100-3, movably connected to the inner opening rocker arm shaft 100-1 and connected to one end of the inner opening rocker arm 100-2, for contacting the outer opening linkage plate 90-2 and actuating the outer opening linkage plate 90-2; and a fourth torsion spring 100-4, sleeved on the inner opening rocker arm shaft 100-1 and connected between the inner opening rocker arm 100-2 and the upper cover 10-2;

[0096] The inward-opening rocker arm shaft 100-1 is a stepped shaft;

[0097] The inward-opening rocker arm 100-2 has an arc-shaped plate structure;

[0098] The contact block 100-3 is made of plastic, which will not damage the external opening linkage plate 90-2 when it comes into contact with it, and also reduces noise.

[0099] The fourth torsion spring 100-4 is a common structure in the prior art. One pin is connected to the inner rocker arm 100-2, and the other pin is connected to the upper cover 10-2. It is used to generate torque, which is beneficial for the inner rocker arm 100-2 to return to its original position.

[0100] Another implementation method:

[0101] like Figure 1 , Figure 2 , Figure 4 As shown; in practice, it also includes: a connecting plate 110, which is connected between the first shaft 30 and the second shaft 40, and one end of the connecting plate 110 is blocked by the locking linkage arm 50-1;

[0102] The connecting plate 110 is made of bent sheet metal and has an approximate "L" shape. It is connected between the first shaft 30 and the second shaft 40, which helps to improve the structural reliability of the first shaft 30 and the second shaft 40 and prevents the first shaft 30 and the second shaft 40 from rotating (if the first shaft 30 and the second shaft 40 rotate, wear will occur between them and the outer shell 10, reducing their service life and generating noise).

[0103] Another implementation method:

[0104] like Figure 1 , Figure 2 , Figure 4 As shown; in practice, it also includes: a shock-absorbing block 120, connected to the main housing 10-1, for contacting the locking linkage arm 50-1;

[0105] The damping block 120 is made of rubber and is roughly "P" shaped. It reduces noise and improves structural reliability. Anyone skilled in the art can directly and without doubt know how to set it up after seeing the disclosed content, without needing to put in creative effort or conduct excessive experiments.

[0106] The working principle is as follows: After receiving the electrical signal for unlocking the car key, the motor 20-1 is activated, which in turn drives the worm gear 20-2 to rotate. The worm gear 20-2 drives the locking linkage arm 50-1 to rotate around the first shaft 30 as the rotation center. The locking linkage arm 50-1 moves the sliding arm 80 to the unlock position, realizing electric unlocking and preparing for opening the car door from the outside / inside.

[0107] Opening the car door from the outside: The outward opening rocker arm 90-4 is pulled (pulling means being linked by the car door handle, which is a structure in the prior art and is not the inventive point of this utility model, and will not affect the understanding of the technical solution of this utility model by those skilled in the art), the outward opening rocker arm 90-4 is linked to the sliding arm 80 and the outward opening linkage plate 90-2 to move, the sliding arm 80 is linked to the pawl assembly 70 to rotate around the second axis 40 as the rotation center, the pawl 70-1 is separated from the ratchet 60-1, the ratchet 60-1 is released, and the car door can be opened;

[0108] Opening the car door from the inside: The inward opening rocker arm 100-2 is pulled (pulling means being linked by the inner door handle, which is a structure in the prior art and is not the inventive point of this utility model, and will not affect the understanding of the technical solution of this utility model by those skilled in the art), the inward opening rocker arm 100-2 moves the outer opening linkage plate 90-2 through the contact block 100-3, the outer opening linkage plate 90-2 moves together with the sliding arm 80, the sliding arm 80 moves together with the pawl assembly 70 around the second axis 40 as the rotation center, the pawl 70-1 separates from the ratchet 60-1, the ratchet 60-1 is released, and the car door can be opened;
