[0099] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0100] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0101] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0102] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0103] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0104] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be positioned "above" the other component or feature.

In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are explained, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0106] Figure 1 It is a structural schematic diagram of a side door lock according to an embodiment of the present disclosure.

[0107] like Figure 1 As shown, the side door lock of the present disclosure may include components such as a lock body 100 , a lock tongue component 200 , a pawl assembly 300 , and an electric unlocking assembly 400 .

[0108] The lock body 100 can form the housing portion of the side door lock of the present disclosure, for example, it can include a back plate, a cover, and other structures. Accordingly, components such as the lock tongue component 200 and the pawl assembly 300 can be mounted on the back plate and / or the cover. The mounting methods of these components can be implemented using methods known in the art, and will not be detailed in this disclosure.

[0109] In some embodiments of the present disclosure, the bolt member 200 is rotatably disposed on the lock body 100, and the rotation axis of the bolt member 200 relative to the lock body 100 is the first axis. When the bolt member 200 rotates, the bolt member 200 can include at least a locked position and an unlocked position.

[0110] Figure 2 1 is a schematic structural diagram of a bolt component and a pawl assembly according to one embodiment of the present disclosure. Figure 3 It is a structural schematic diagram of a lock tongue component and a pawl assembly from another angle according to an embodiment of the present disclosure.

[0111] like Figure 2 and Figure 3 As shown, in a specific embodiment, the lock tongue component 200 can be located in a locked position, a semi-locked position, and an unlocked position; in other words, when the lock tongue component 200 is driven to rotate, the lock tongue component 200 can move to one of the locked position, the semi-locked position, and the unlocked position.

[0112] by Figure 2In the state shown, the locking tongue component 200 is in the locked position. Figure 2 In the direction shown, when the lock tongue component 200 is rotated counterclockwise, it can be in the semi-locked position and the unlocked position. Conversely, when the lock tongue component 200 is in the unlocked position and rotated clockwise, it can be in the semi-locked position and the locked position. When the lock tongue component 200 is in the locked position, the side door lock is in the locked state; when the lock tongue component 200 is in the unlocked position, the side door lock is in the unlocked state.

[0113] In the present disclosure, the counterclockwise movement of the lock tongue component 200 (i.e., the unlocking process) can be achieved by the elastic force of the return spring. The clockwise movement of the lock tongue component 200 (i.e., the locking process) can be achieved by the pushing force applied to the lock tongue component 200 by a striker, or by the electric locking mechanism pulling the lock tongue component 200. In this case, the side door lock has an electric locking function. This electric locking mechanism can be implemented using existing solutions, and this disclosure will not elaborate on this in detail.

[0114] Refer again Figure 2 and Figure 3 In the present disclosure, the pawl assembly 300 is used to cooperate with the lock tongue component 200 and at least keep the lock tongue component 200 in the locked position; specifically, the pawl assembly 300 of the present disclosure can keep the lock tongue component 200 in the locked position and the semi-locked position.

[0115] In a specific embodiment, the pawl assembly 300 includes a first pawl component 310 , a second pawl component 320 , and a sliding pawl component 330 .

[0116] The first pawl component 310 is rotatably disposed on the lock body 100. The rotation axis of the first pawl component 310 relative to the lock body 100 is the second axis, and the second axis can be parallel to or substantially horizontal with the first axis. Figures 1 to 3 In the orientation shown, the first axis and the second axis may both be disposed generally vertically.

[0117] The second pawl component 320 is rotatably disposed on the lock body 100. The rotation axis of the second pawl component 320 relative to the lock body 100 is a third axis, which is parallel or substantially parallel to the second axis and spaced apart from the second axis.

[0118] Thus, the first pawl member 310 can hold the bolt member 200 at the locked position, and the second pawl member 320 can hold the bolt member 200 at the semi-locked position.

[0119] The second pawl component 320 of the present disclosure can be driven and rotated by the electric unlocking assembly 400 to unlock the side door lock. Figure 2 In the direction shown, when the second pawl component 320 is driven to rotate counterclockwise, it can drive the sliding pawl component 330 to move and drive the first pawl component 310 to move, thereby unlocking the side door lock.

[0120] Specifically, the second pawl component 320 includes a second pawl first groove feature 321 and a second pawl second groove feature 322; the rotating shaft of the first pawl component 310 is slidably disposed in the second pawl first groove feature 321, thereby, when the second pawl component 320 is driven and rotated, the first pawl component 310 will not affect the rotation of the second pawl component 320.

[0121] The sliding pawl component 330 includes a first axis feature 331 of the sliding pawl, which is slidably arranged in the second groove feature 322 of the second pawl, and when the second pawl component 320 rotates, it can drive the sliding pawl component 330 to move, that is, generate a sliding action, thereby, the sliding pawl component 330 can leave from between the first pawl component 310 and the limiting component 340, and allow the first pawl component 310 to rotate counterclockwise, and the first pawl component 310 can release the lock tongue component 200, and enable the lock tongue component 200 to leave the locked position and move toward the semi-locked position.

[0122] Refer again Figure 3 The sliding pawl component 330 can also drive the first pawl component 310 to rotate. Specifically, when the second pawl component 320 rotates counterclockwise, the sliding pawl first axis feature 331 of the sliding pawl component 330 can move along the tangential direction of the circle with the third axis as the center line. At this time, the sliding pawl component 330 will push the first pawl component 310 to rotate counterclockwise.

[0123] Those skilled in the art should know that the reverse movement of the first pawl component 310 , the second pawl component 320 and the sliding pawl component 330 can be achieved by a return spring, which will not be described in detail here.

[0124] Generally speaking, during the unlocking process of the side door lock, the second pawl component 320 will be driven to rotate counterclockwise; and when the second pawl component 320 is allowed to rotate clockwise and reset, the second pawl component 320 can rotate clockwise and reset under the action of the reset force provided by the reset spring.

[0125] Figure 4 It is a schematic diagram of the principle of a side door lock according to one embodiment of the present disclosure. Figure 5 Schematic diagram of the structure of an electric lock assembly according to one embodiment of the present disclosure.

[0126] The electric unlocking assembly 400 is used to cooperate with the pawl assembly 300 so that the pawl assembly 300 can release the lock tongue component 200; in other words, the electric unlocking assembly 400 of the present disclosure can drive the second pawl component 320 of the pawl assembly 300 to rotate counterclockwise and unlock the side door lock.

[0127] Specifically, the electric unlocking assembly 400 of the present disclosure includes a first motor 410 and a worm gear assembly 420 drivingly connected to the first motor 410. Furthermore, the worm gear assembly 420 may include a worm gear component 421 and a safety drive 422. One end of the safety drive 422 is rotatably connected to the worm gear component 421, and the other end (free end) of the safety drive 422 extends outward from the worm gear component 421. A worm is provided on the output shaft of the first motor 410, and the worm is capable of cooperating with the worm gear component 421, so that rotation of the worm causes rotation of the worm gear component 421.

[0128] like Figure 5 As shown, the safety driving member 422 includes a first side surface 422A and a second side surface 422B. Figure 5 In the direction shown, the first side surface 422A forms the upper surface of the safety driving member 422, and the second side surface 422B forms the lower surface of the safety driving member 422. More preferably, the first side surface 422A is formed as a concave arc surface, and the second side surface 422B is formed as a convex arc surface, so that the safety driving member 422 is formed as a curved rod-shaped member as a whole.

[0129] A first retaining spring 423 is provided on the worm wheel component 421 of the worm wheel assembly 420. The first retaining spring 423 is used to limit the safety driving member 422 to the initial position, and when the safety driving member 422 leaves the initial position, the first retaining spring 423 is used to reset the safety driving member 422 to the initial position.

[0130] Specifically, the first retaining spring 423 can be a torsion spring, which can be mounted on the rotating shaft of the worm gear component 421. The two ends of the first retaining spring 423 are arranged roughly in parallel. Moreover, two columnar portions 422C are provided on the safety drive 422. The two ends of the first retaining spring 423 are used to clamp the columnar portions 422C, so that the first retaining spring 423 can limit the safety drive 422 to the initial position.

[0131] The worm gear component 421 of the present disclosure rotates about a fourth axis relative to the lock body 100, and the safety driver 422 rotates about a fifth axis relative to the lock body 100. The fourth and fifth axes are arranged parallel or substantially parallel to each other. The worm gear component 421 has a tangent plane passing through the fifth axis, which is tangent to a cylindrical surface centered on the fourth axis. The fourth axis is located on one side of the tangent plane, and the other end of the safety driver 422 is located on the other side of the tangent plane. At this point, an angle is formed between the safety driver 422 and the tangent plane (the angle is formed between the line connecting one end and the other end of the safety driver 422 and the tangent plane). The value of this angle can change as the safety driver 422 rotates.

[0132] In a preferred embodiment, the diameter of the columnar portion 422C can be the same as the distance between the two ends of the first retaining spring 423. In this case, the distance between the two ends of the first retaining spring 423 is at a minimum. When the safety driver 422 rotates, the distance between the two ends of the first retaining spring 423 increases as the included angle changes. At this time, the two ends of the first retaining spring 423 tend to contract inward, thereby causing the safety driver 422 to return to its initial position.

[0133] Figure 6 2 is a schematic structural diagram of an electric lock assembly according to an embodiment of the present disclosure from another angle. Figure 7 It is a structural schematic diagram of a partial structure of a side door lock according to an embodiment of the present disclosure.

[0134] like Figure 6 and Figure 7 As shown, the electric unlocking assembly 400 of the present disclosure can also operate the rod component 430, which cooperates with the worm gear assembly 420 to drive the operating rod component 430 to rotate through the rotation of the worm gear assembly 420; wherein, when the operating rod component 430 rotates, it can push the pawl assembly 300 to move.

[0135] Specifically, if Figure 6 and Figure 7 As shown, the operating lever component 430 includes a first operating lever arm feature 431, a second operating lever arm feature 432, a third operating lever arm feature 433, and an operating lever slot feature 434. The first operating lever arm feature 431, the second operating lever arm feature 432, and the third operating lever arm feature 433 are all formed as arm portions of the operating lever component 430. The first operating lever arm feature 431 can cooperate with the cam structure 421A on the worm gear component 421, so that when the worm gear component 421 rotates, it can push the operating lever component 430 to rotate.

[0136] Specifically, Figure 6In the direction shown, when the worm wheel component 421 rotates clockwise, it can push the operating rod component 430 to rotate counterclockwise. Figure 5 In the direction shown, when the worm wheel component 421 rotates counterclockwise, it can push the operating lever component 430 to rotate clockwise. As a result, the operating lever second arm feature 432 of the operating lever component 430 can push the second pawl component 320 to rotate. Figure 2 and Figure 3 In the direction shown, the second pawl component 320 will rotate counterclockwise, thereby unlocking the side door lock.

[0137] Of course, the operating lever component 430 of the present disclosure can rotate counterclockwise (in degrees) under the action of the return spring. Figure 5 direction shown).

[0138] The side door lock of the present disclosure may further include a first manual unlocking assembly 500, which is used to cooperate with the pawl assembly 300 to enable the pawl assembly 300 to release the lock tongue component 200; that is, the first manual unlocking assembly 500 of the present disclosure can be configured to drive the second pawl component 320 of the pawl assembly 300 to rotate. Specifically, as Figure 5 As shown, the first manual unlocking assembly 500 is an outward opening pull rod assembly, which may include an outward opening pull rod 510 and an outward opening transmission rod 520. The outward opening pull rod 510 is rotatably mounted on the lock body 100, one end of which can be connected to the side door outward opening handle. When the side door outward opening handle is pulled, the outward opening pull rod 510 can rotate clockwise. The outward opening transmission rod 520 is rotatably mounted on the lock body 100, and one end of the outward opening transmission rod 520 cooperates with the other end of the outward opening pull rod 510. As a result, when the outward opening pull rod 510 rotates clockwise, it can push the outward opening transmission rod 520 to rotate counterclockwise.

[0139] The safety lever 600 is configured to rotate about a sixth axis and has a first position and a second position; when the safety lever 600 is in the first position, the first manual unlocking assembly 500 is allowed to drive the pawl assembly 300 to move; when the safety lever 600 is in the second position, the first manual unlocking assembly 500 is not allowed to drive the pawl assembly 300 to move.

[0140] Figures 8 to 10 FIG. 1 is a schematic diagram of a movement of a safety lever driven from a first position to a second position according to an embodiment of the present disclosure. Figures 11 to 13 FIG. 1 is a schematic diagram of a movement of a safety lever driven from a second position to a first position according to an embodiment of the present disclosure.

[0141] refer to Figures 8 to 13In the present disclosure, the worm gear assembly 420 is configured to drive the safety lever 600 from the first position to the second position, or to drive the safety lever 600 from the second position to the first position.

[0142] Specifically, an arc-shaped groove 610 is provided at the lower end of the safety rod 600, and one end of the safety release rod 700 is slidably and rotatably arranged in the arc-shaped groove 610 of the safety rod 600, and the other end of the safety release rod 700 is slidably and rotatably arranged in the operating rod groove feature 434 of the operating rod component 430. Therefore, when the safety rod 600 is driven and rotated, it can drive the safety release rod 700 to produce horizontal displacement.

[0143] Among them, when the safety lever 600 is in the first position, the outward opening transmission rod 520 of the first manual unlocking assembly 500 can drive the safety unlocking lever 700 (that is, the other end of the safety unlocking lever 700 is located within the motion envelope of the outward opening transmission rod 520), and drive the operating lever component 430 to rotate through the safety unlocking lever 700; on the other hand, when the safety lever 600 is in the second position, the first manual unlocking assembly 500 cannot drive the safety unlocking lever 700. At this time, the other end of the safety unlocking lever 700 is located outside the motion envelope of the outward opening transmission rod 520.

[0144] In a preferred embodiment, a limiting column 710 is provided at one end of the safety release rod 700, and a second retaining spring 601 is provided on the safety pull rod 600. The second retaining spring 601 cooperates with the limiting column 710 to limit one end of the safety release rod 700 to the approximate middle position of the arc groove 610 of the safety pull rod 600.

[0145] More preferably, a limiting protrusion 620 is provided at the lower end of the safety lever 600 , and the two ends of the second clamping spring 601 are used to clamp the limiting column 710 and the limiting protrusion 620 ; wherein the two ends of the second clamping spring 601 are arranged substantially in parallel.

[0146] In the present disclosure, the second clamping spring 601 may be a torsion spring, which is sleeved on the rotating shaft of the safety lever 600. Moreover, the second clamping spring 601 and the first clamping spring 423 have the same / similar working principles, which will not be described in detail in this disclosure.

[0147] The following will be combined Figures 8 to 13 The specific structure of the safety lever 600 and its matching relationship with the worm gear assembly 420 will be described below.

[0148] like Figures 8 to 13As shown, the safety lever 600 of the present disclosure includes a first matching portion 630 and a second matching portion 640 ; the safety driving member 422 selectively matches with the first matching portion 630 or the second matching portion 640 to push the safety lever 600 to rotate in different rotation directions.

[0149] When the safety lever 600 is located at the first position, the safety driving member 422 can cooperate with the first matching portion 630 to drive the safety lever 600 from the first position to the second position.

[0150] Specifically, the first matching portion 630 includes a first groove formed on a side of the safety lever 600 , and an opening of the first groove faces the worm gear assembly 420 .

[0151] The first groove includes a first upper side wall 631 and a first lower side wall 632; when the safety lever 600 is in the first position, the other end of the safety drive member 422 contacts the first upper side wall 631 (eg Figure 9 At this time, since the safety lever 600 is in the first position, it cannot continue to rotate counterclockwise. Therefore, as the worm wheel component 421 rotates further, the safety driving component 422 will slide along the inner side wall of the first groove and cooperate with the first lower side wall 632 (as shown in FIG. Figure 10 shown).

[0152] The safety lever 600 is formed with a protrusion 650, which is used to form the first upper side wall 631 of the first groove. Figure 10 In the state shown, when the other end of the safety driving member 422 is engaged with the first lower side wall 632, the protrusion 650 contacts the first side surface of the safety driving member 422, and makes the angle of the safety driving member 422 larger and larger, so as to push the safety lever 600 to rotate clockwise (as shown in FIG. Figures 8 to 10 in the direction shown), and moves from the first position to the second position.

[0153] Figure 11 The state shown is that the safety lever 600 is located at the second position. Figures 11 to 13 As shown, when the safety lever 600 is located at the second position, the safety driving member 422 can cooperate with the second matching portion 640 to drive the safety lever 600 from the second position to the first position.

[0154] Specifically, the second matching portion 640 includes a second groove formed on a side of the safety lever 600 , and an opening of the second groove faces the worm gear assembly 420 .

[0155] In other words, the second groove of the present disclosure is located above the first groove, and the portion between the first groove and the second groove is the aforementioned protrusion 650 .

[0156] The second groove includes a second upper sidewall 641 and a second lower sidewall 642. When the safety lever 600 is in the second position, the other end of the safety driver 422 contacts the second upper sidewall 641, pushing the safety lever 600 to rotate counterclockwise and move from the second position to the first position. In other words, when the safety lever 600 is in the second position, the other end of the safety driver 422 can pass over the first groove and directly engage with the second groove instead of the first groove.

[0157] The protrusion 650 is used to form the second lower side wall 642 of the second groove. When the other end of the safety driving member 422 is matched with the second upper side wall 641 , the protrusion 650 contacts the second side surface 422B of the safety driving member 422 .

[0158] Generally speaking, when the safety lever 600 is in the first position, the upper end of the safety lever 600 is away from the worm gear assembly 420, and the lower end of the safety lever 600 is close to the worm gear assembly 420. When the safety lever 600 is in the second position, the upper end of the safety lever 600 is close to the worm gear assembly 420, and the lower end of the safety lever 600 is away from the worm gear assembly 420. In this way, the safety lever 600 of the present disclosure can be easily matched with the safety drive member 422.

[0159] Based on the above structure, when the side door lock of the present disclosure is working, when the first motor 410 rotates in the first direction, the worm gear component 421 of the electric unlocking assembly 400 will rotate counterclockwise (in degrees). Figure 5 The worm wheel component 421 of the electric unlocking assembly 400 rotates clockwise (in the direction shown in FIG. 1 ) and drives the pawl component 300 to move by the operating rod component 430 to unlock the side door. Figure 5 In the direction shown, the safety actuator 422 actuates the safety lever 600, switching the safety lever 600 between the engaged and disengaged states. When the safety lever 600 is in the first position, the safety lever 600 is in the disengaged state, allowing the side door lock to be unlocked via the outward release lever 510. When the safety lever 600 is in the second position, the safety lever 600 is in the engaged state, preventing the side door lock from being unlocked via the outward release lever 510.

[0160] Based on the above structure, the side door lock of the present disclosure can be unlocked directly by the electric unlocking assembly. Moreover, the electric unlocking assembly can also switch the state of the safety lever 600. At the same time, the electric unlocking assembly performs these two functions in forward and reverse rotation. Accordingly, when the side door lock is electrically unlocked, it will not affect the armed or disarmed state of the safety lever 600.

[0161] Figure 14It is a structural schematic diagram of a lock cylinder pull rod according to an embodiment of the present disclosure.

[0162] like Figure 4 and Figure 14 As shown, the side door lock of the present disclosure may also include a lock cylinder pull rod 101, thereby enabling the side door lock to be installed on the side door corresponding to the driver's seat. Accordingly, the side door lock of the present disclosure can be opened and closed using a key. Specifically, when the lock cylinder 102 rotates, it can drive the lock cylinder pull rod 101 to move, and through the lock cylinder pull rod 101, it drives the safety pull rod 600, and causes the safety pull rod 600 to be located in the first position or the second position. Furthermore, when the side door lock needs to be opened, the safety pull rod 600 can be driven to the first position, and then the side door lock can be unlocked using the first manual unlocking assembly 500; when the side door lock needs to be closed, the safety pull rod 600 can be driven to the second position, thereby preventing the side door lock from being unlocked even if the first manual unlocking assembly 500 is pulled.

[0163] Refer again Figure 6 The side door lock of the present disclosure may also have an electric child safety function. Specifically, the side door lock of the present disclosure further includes a child safety assembly 800. When the child safety assembly 800 is in the safety-on state, the side door lock cannot be unlocked by the second manual unlocking assembly 900. When the child safety assembly 800 is in the safety-off state, the side door lock can be unlocked by the second manual unlocking assembly 900.

[0164] Specifically, the second manual unlocking assembly 900 of the present disclosure may include an inner opening pull rod, which is rotatably arranged on the lock body 100, and the inner opening pull rod has the same rotation axis as the operating rod component 430, and the inner opening pull rod can selectively cooperate with the operating rod third arm feature 433 of the operating rod component 430 to selectively drive the operating rod component 430 to rotate.

[0165] Specifically, the child-safety component 800 may include a second motor 810, which is arranged on the lock body, and a worm is provided on the output shaft of the second motor 810, which can engage with the child-safety worm wheel 820 and rotate the child-safety worm wheel 820 through the rotation of the worm.

[0166] An arc-shaped hole is provided on the child-safety worm gear 820, and one end of the child-safety connecting rod 830 is rotatably and rotatably arranged in the arc-shaped hole of the child-safety worm gear 820, and an elongated hole is provided on the inner pull rod, and the other end of the child-safety connecting rod 830 is rotatably and slidably arranged in the elongated hole.

[0167] Therefore, Figure 7In the direction shown, when the child-safety link 830 is driven and moves rightward (e.g., to the right end of the elongated slot), the inner opening lever is in transmission connection with the operating lever component 430. Specifically, when the inner opening lever is driven and rotated clockwise, it drives the operating lever component 430 to rotate clockwise, thereby unlocking the side door lock. On the other hand, when the child-safety link 830 is driven and moves leftward (e.g., to the left end of the elongated slot), the clockwise rotation of the inner opening lever does not drive the operating lever component 430 to rotate clockwise. As a result, the side door lock cannot be opened via the inner opening lever, thus achieving the child-safety function.

[0168] In another embodiment, the child safety link 830 of the present disclosure can be manually operated and moved, thereby enabling the child safety function of the present disclosure to be manually turned on or off.

[0169] In a preferred embodiment, the side door lock may further include a first position detection device, which may be a travel switch that detects the position of the child-safety worm gear 820. When the child-safety component is in the safety-enclosed state, the travel switch can be actuated and closed. Consequently, the controller can disable the unlocking motion of the first motor based on the closed state of the travel switch. In this case, the side door lock cannot be unlocked via the electric unlocking component 400. In other words, the vehicle controller can disable or enable the electric unlocking function based on the state of the child-safety component.

[0170] In another preferred embodiment, the side door lock may further include a second position detection device, which may be a travel switch, and detects the position of the safety lever via the travel switch. When the safety lever is in the safety position, the travel switch can be actuated and closed. Thus, the controller can disable the unlocking motion of the first motor based on the closed state of the travel switch. In this case, the side door lock cannot be unlocked via the electric unlocking assembly 400. In other words, the vehicle controller can disable or enable the electric unlocking function based on the state of the safety lever.

[0171] Generally speaking, when the side door of the present invention is in use, the electric unlocking function and the manual unlocking function do not affect each other. In the power-off state after the whole vehicle collision, it can also be safely unlocked by the inner opening rod, thereby improving the safety performance of the whole vehicle.

[0172] According to another aspect of the present disclosure, a motor vehicle is provided, which includes the above-mentioned side door lock.
