Abstract
Description
Technical Field
[0001] This disclosure relates to a side door lock and a motor vehicle. Background Technology
[0002] With the development of vehicle electrification and intelligence, electric door locks have become widespread on vehicle covers or doors.
[0003] However, for the sake of door reliability, the vehicle's door locks need to have a manual unlocking function. For example, the side door locks can be unlocked through both the inward and outward door handles.
[0004] In existing side door locks, the safety components for the inward-opening door handle and the outward-opening door handle are set as different components. This results in a large number of parts in existing side door locks. On the one hand, this leads to a larger size of the side door lock, making it difficult to adapt to the car door. On the other hand, it also leads to a shorter trouble-free working time for the side door lock. Utility Model Content

[0084] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0085] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0086] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0087] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0088] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0089] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0090] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0091] Figure 1 This is a schematic diagram of a side door lock according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of a side door lock according to one embodiment of the present disclosure from another angle. Figure 3 This is a schematic diagram of the internal structure of a side door lock according to one embodiment of the present disclosure. Figure 4 This is a schematic diagram of the internal structure of a side door lock according to one embodiment of the present disclosure from another angle. Figure 5 This is a structural schematic diagram of the internal structure of a side door lock according to one embodiment of the present disclosure from another angle.
[0092] like Figures 1 to 5 As shown, the side door lock disclosed herein may include structures such as a lock body 100, a bolt component 200, and a pawl assembly 300.
[0093] The lock body 100 can be formed as the housing part of the side door lock of this disclosure. For example, it may include structures such as a back plate and a cover. Correspondingly, components such as the bolt member 200 and the pawl assembly 300 can be installed on the back plate and / or the cover. The installation method of these components can be implemented by means of the prior art, and will not be described in detail in this disclosure.
[0094] In one embodiment, such as Figures 1 to 5 As shown, the lock body 100 includes an opening slot for the lock pin to pass through. A through hole 110 is provided on the lock body 100 at the opening slot for one end of a tool to pass through, and the tool drives the safety component 600 to rotate. Thus, the side door lock of this disclosure can place the emergency safety feature (unlocking and locking) at the opening slot (i.e., the fish mouth), which is convenient for operation. The door does not need to have an additional hole to realize the emergency safety feature, thus ensuring the aesthetics of the vehicle body.
[0095] In addition, the rotation axis of the latch component 200 and the rotation axis of the pawl component 310 are located on opposite sides of the opening groove. The rotation axis of the latch component 200 is further away from the opening end of the opening groove than the rotation axis of the pawl component 310. Therefore, the mechanical structure of the latch component 200 and the pawl component 310 of the side door lock disclosed herein is reasonable, and it can be unlocked and locked more easily.
[0096] In a preferred embodiment, the contact position between the latch member 200 and the lock cylinder is closer to the opening end of the slot than the axis of rotation of the latch member 200. In other words, in the side door lock of this disclosure, the axis of rotation of the latch member 200 is arranged in the opposite direction to the opening direction of the locking point of the lock cylinder, thereby allowing the side door lock to be easily opened.
[0097] That is, when the pawl component 310 releases the latch component 200, the door can be pulled to apply force to the latch component 200, causing the latch component 200 to rotate clockwise and unlocking the side door lock.
[0098] When the side door lock is installed on the vehicle door, the rotation axis of the pawl component 310 is higher than the rotation axis of the latch component 200. Therefore, when liquid enters the interior of the side door lock of this disclosure, the liquid will not freeze the pawl component 310 after freezing, thus preventing the pawl component 310 from rotating and improving the reliability of the side door lock.
[0099] In some embodiments of this disclosure, the latch member 200 is rotatably disposed on the lock body 100, and the axis of rotation of the latch member 200 relative to the lock body 100 is a first axis. When the latch member 200 rotates, the latch member 200 can include at least a locked position and an unlocked position.
[0100] In a specific embodiment, such as Figure 3 As shown, the locking tongue component 200 of this disclosure is in a locked position, a partially locked position, and an unlocked position. Figure 3 As shown, the latch component 200 is in the locked position. Figure 3 As shown in the direction, when the latch component 200 rotates clockwise, it can move sequentially from the locked position to the half-locked position and then to the unlocked position. When the latch component 200 is in the unlocked position, it can release the latch, thereby unlocking the side door lock.
[0101] In a preferred embodiment, a latch damping block 210 may be provided on the lock body 100. The latch component 200 has a notch. When the latch component 200 is in the locked position, the bottom wall of the notch can contact the latch damping block 210, thereby buffering and damping the locking process of the latch component 200. Additionally, when the latch component 200 is in the unlocked position, the protruding structure on the latch component 200 can contact the side wall of the latch damping block 210, thus the latch damping block 210 can also buffer and dampen the unlocking process of the latch component 200.
[0102] In this disclosure, Figure 3 As shown, the unlocking process of the latch component 200 can be achieved by the restoring force provided by the return spring. Those skilled in the art will understand that when the side door lock of this disclosure is installed on the side door of a vehicle and the side door is closed, the striker mounted on the vehicle body will push the latch component 200 to rotate counterclockwise, thereby enabling the side door lock to engage.
[0103] Figure 6 This is a schematic diagram of a side door lock according to one embodiment of the present disclosure. Figure 7 This is a schematic diagram of a side door lock according to one embodiment of the present disclosure from another angle. Figure 8 This is a schematic diagram of a side door lock from another angle according to one embodiment of the present disclosure. Figure 9 This is a schematic diagram of another state of the side door lock according to one embodiment of the present disclosure.
[0104] like Figures 3 to 7 As shown, the pawl assembly 300 of this disclosure is used to cooperate with the latch member 200 and at least to hold the latch member 200 in a locked position. Specifically, the pawl assembly 300 of this disclosure includes a pawl member 310 and a pawl drive member 320 for driving the pawl member 310 to rotate; wherein, the pawl member 310 is configured to be rotatable and has a stop position, an intermediate position, and a release position. When the pawl member 310 is in the stop position, it can hold the latch member 200 in the locked position. When the pawl member 310 is in the intermediate position, it can hold the latch member 200 in a semi-locked position. When the pawl member 310 is in the release position, the latch member 200 is in the unlocked position, at which time the pawl member 310 will be in close contact with the latch member 200, and the latch member 200 restricts the reset action of the pawl member 310.
[0105] Specifically, with Figure 3In the indicated state, the pawl component 310 is in the stop position. When the pawl component 310 is driven by the pawl drive component 320 and rotates clockwise, it can move sequentially from the stop position to the intermediate position and then to the release position. Similarly, when the latch component 200 rotates counterclockwise and locks the side door lock, the pawl component 310 will be allowed to rotate counterclockwise. At this time, under the action of the reset force provided by the return spring, the pawl component 310 will rotate counterclockwise and move sequentially from the release position to the intermediate position and then to the stop position.
[0106] In a preferred embodiment, such as Figures 4 to 7 As shown, the pawl assembly 300 of this disclosure also includes a pawl signal driver 330 and a pawl signal switch 340. The pawl signal driver 330 is used to trigger the pawl signal switch 340. The pawl signal switch 340 is triggered when the pawl component 310 rotates and allows the locking tongue component 200 to leave the locking position.
[0107] In a preferred embodiment, the pawl component 310, the pawl drive 320, and the pawl signal drive 330 are all configured to rotate relative to the lock body 100. In a preferred embodiment, the pawl component 310, the pawl drive 320, and the pawl signal drive 330 have the same axis of rotation, and the pawl drive 320 can drive the pawl signal drive 330 to rotate when it rotates. Figure 7 As shown, when the pawl drive 320 rotates counterclockwise, it can push the pawl signal drive 330 to rotate counterclockwise synchronously, thereby unlocking the side door lock. Simultaneously, when the side door lock is in the unlocked state, the pawl signal switch 340 is triggered by the pawl signal drive 330. Furthermore, when the side door lock is in the partially locked state, the pawl signal switch 340 is also triggered by the pawl signal drive 330.
[0108] During the locking process of the side door lock, when the pawl drive 320 rotates clockwise under the action of the return spring and other return forces, the pawl signal switch 340 will be blocked by the latch component 200 and will not rotate clockwise together with the pawl drive 320. At this time, the pawl signal drive 330 will continuously trigger the pawl signal switch. When the latch component 200 is in the locked position, the pawl signal drive 330 is allowed to rotate clockwise and the pawl signal switch 340 is released.
[0109] Structurally speaking, such as Figure 16As shown, the latch component 200 of this disclosure has a boss portion 220; the pawl signal drive 330 has a limiting component 331, which can cooperate with the boss portion 220 in the height direction. Moreover, when the latch component 200 is in the unlocked position, the limiting component 331 can closely abut the boss portion 220 of the latch component 200, thereby preventing the pawl signal drive 330 from rotating clockwise.
[0110] During the locking process, the latch component 200 rotates. At this time, the limiting component 331 will slide relative to the boss portion 220. When the latch component 200 rotates to the locked position, the limiting component 331 will slide to the end of the boss portion 220. At this time, the boss portion 220 will no longer limit the limiting component 331, and the pawl signal drive component 330 will rotate clockwise and release the pawl signal switch 340.
[0111] like Figure 7 As shown, the side door lock of this disclosure also includes a push rod component 400, which is driven to move between a first position (locked position) and a second position (unlocked position); Figure 7 The directions shown indicate that the first position is where the push rod component 400 moves to the left to its maximum stroke, and the second position is where the push rod component 400 moves to the right to its maximum stroke.
[0112] Additionally, the push rod component 400 includes a disengaged state and an engaged state. When the push rod component 400 is in the disengaged state and moves from left to right, it cannot push the pawl assembly 300 (i.e., the pawl drive 320) to rotate. When the push rod component 400 is in the engaged state and moves from left to right (i.e., from the first position to the second position), the push rod component 400 can engage with the pawl drive 320 to push the pawl drive 320 to rotate counterclockwise. Figure 7 (as shown in the direction), thereby unlocking the side door lock.
[0113] like Figures 4 to 7 As shown, the side door lock of this disclosure also includes a transition component 500, which is configured to rotate about a second axis. One end of the push rod component 400 is rotatably connected to the transition component 500. The push rod component 400 rotates about a third axis relative to the transition component 500. The second axis and the third axis are spaced apart.
[0114] In other words, when the transition member 500 is in a stationary state, the push rod member 400 can rotate relative to the transition member 500. Figure 7 As shown, the push rod component 400 is in the engaged state and located in the first position. Figure 7As shown in the direction, when the transition component 500 rotates counterclockwise, it can push the push rod component 400 to move to the right. At this time, the push rod component 400 will push the pawl drive component 320 to rotate counterclockwise, thereby unlocking the side door lock.
[0115] In this disclosure, the pawl drive 320 can also be limited, buffered, and damped by the pawl damper 350. Specifically, the pawl damper 350 can be fixed to the lock body 100, and when the pawl drive 320 contacts the pawl damper 350, the pawl component 310 is in a stop position.
[0116] like Figures 3 to 9 As shown, the side door lock of this disclosure also includes an outward-opening manual unlocking component 510 and an inward-opening manual unlocking component 520, wherein the outward-opening manual unlocking component 510 is used to drive the push rod component 400 to move from the first position to the second position; and the inward-opening manual unlocking component 520 is used to drive the push rod component 400 to move from the first position to the second position.
[0117] In other words, when the outward-opening manual unlocking component 510 and the inward-opening manual unlocking component 520 of this disclosure are activated, both can unlock the side door lock.
[0118] Specifically, the outward-opening manual unlocking component 510 is configured to rotate about a fourth axis, wherein when the outward-opening manual unlocking component 510 is driven and rotated, it drives the transition component 500 to rotate. Figure 7 As shown, when the external manual unlocking component 510 is pulled to rotate clockwise, it can push the transition component 500 to rotate counterclockwise. Alternatively, the clockwise rotation of the transition component 500 can be achieved by the reset force provided by the reset spring.
[0119] Similarly, the inward-opening manual unlocking assembly 520 is configured to rotate about a fifth axis, wherein when the inward-opening manual unlocking assembly 520 is driven and rotated, it drives the transition member 500 to rotate. Figure 7 As shown, when the inward-opening manual unlocking component 520 is pulled to rotate clockwise, it can push (or indirectly push) the transition component 500 to rotate counterclockwise, thereby unlocking the side door lock. The specific method by which the inward-opening manual unlocking component 520 drives the transition component 500 to rotate will be described in detail below.
[0120] like Figures 3 to 9As shown, the side door lock of this disclosure also includes a locking component 600, which is driven to move between a locked position and a unlocked position. When the locking component 600 is in the locked position, it pushes the push rod component 400 to a disengaged state. When the push rod component 400 is in the disengaged state and moves from the first position to the second position, it does not drive the pawl assembly 300 to rotate. When the locking component 600 is in the unlocked position, the push rod component 400 is in an engaged state. When the push rod component 400 is in the engaged state and moves from the first position to the second position, it drives the pawl assembly 300 to rotate, thereby unlocking the side door lock.
[0121] by Figure 7 As shown, the safety component 600 is in the unlocked position. Figure 7 As shown, when the safety component 600 is driven and rotates counterclockwise, it can move from the unlocked position to the engaged position. Simultaneously, during the counterclockwise rotation of the safety component 600, it can push the push rod component 400 to swing clockwise relative to the transition component 500, causing the push rod component 400 to move to the disengaged state. Thus, the safety component 600 and the push rod component 400 will... Figure 7 The state shown moves to Figure 9 The state shown.
[0122] exist Figure 7 In the state shown, when the user operates the outward manual unlocking component 510, the outward manual unlocking component 510 can cause the transition component 500 to rotate counterclockwise, thereby allowing the push rod component 400 to move from left to right and push the pawl drive component 320 to rotate, thus unlocking the side door lock.
[0123] exist Figure 9 In the state shown, when the user operates the outward manual unlocking component 510, the outward manual unlocking component 510 can cause the transition component 500 to rotate counterclockwise, thereby allowing the push rod component 400 to move from left to right. However, since the push rod component 400 cannot drive the pawl drive component 320 to rotate, the side door lock cannot be unlocked by the outward manual unlocking component 510.
[0124] exist Figure 9 In the states shown, whether the user can unlock the device when operating the manual unlock component 510 depends on the state of the child protection component 800, which will be explained in detail below.
[0125] In a preferred embodiment, the side door lock of this disclosure further includes a safety drive assembly 610 for driving the safety component 600 to reciprocate between an engaged position and an unengaged position.
[0126] Specifically, the safety drive assembly 610 includes a drive motor 611, a gear component 612, and a shift fork 613; a worm gear is mounted on the output shaft of the drive motor 611; the gear component 612 cooperates with the worm gear to drive the gear component 612 to rotate via the drive motor 611; the shift fork 613 is mounted on the gear component 612; wherein, the safety component 600 includes a groove structure, and one end of the shift fork 613 is movably disposed within the groove structure, so that when the shift fork 613 rotates with the gear component 612, the shift fork 613 drives the safety component 600 to rotate. In a preferred embodiment, the lower end of the shift fork 613 is formed into a ball head, which is disposed within the groove structure, thereby allowing the ball head to slide and / or rotate relative to the sidewall of the groove structure.
[0127] In this disclosure, the gear component 612 can also be a worm gear component, and the gear component 612 can be a sector gear. Furthermore, the engagement between the worm and the gear component 612 is a non-self-locking engagement. That is, when the worm rotates, it can drive the gear component 612 to reciprocate. When the gear component 612 is driven, it can also cause the worm to rotate.
[0128] Figure 10 This is a schematic diagram of the child safety component of a side door lock in the child safety release position according to one embodiment of the present disclosure. Figure 11 This is a schematic diagram of the side door lock child safety component in the child safety release position at another angle according to one embodiment of the present disclosure. Figure 12 This is a schematic diagram of the child safety component of a side door lock in the upper child safety position according to one embodiment of the present disclosure. Figure 13 This is a structural schematic diagram of the child safety component of the side door lock in the upper child safety position according to one embodiment of the present disclosure.
[0129] like Figures 10 to 13 As shown, the side door lock of this disclosure also includes an intermediate transmission component 700, which is configured to rotate about a sixth axis. The inward-opening manual unlocking assembly 520 drives the transition component 500 to rotate via the intermediate transmission component 700. In a preferred embodiment, the intermediate transmission component 700 and the inward-opening manual unlocking assembly 520 have the same axis of rotation, and the intermediate transmission component 700 and the inward-opening manual unlocking assembly 520 may have the same direction of rotation.
[0130] In addition, the side door lock disclosed herein also includes a child safety device 800, which is rotatably disposed in the intermediate transmission component 700. The child safety device 800 rotates about a seventh axis relative to the intermediate transmission component 700 and has a child safety release position and a child safety release position. When the child safety device 800 is in the child safety release position, the inward manual unlocking component 520 can apply a pushing force to the child safety device 800 and push the intermediate transmission component 700 to rotate through the child safety device 800. When the child safety device 800 is in the child safety release position, the inward manual unlocking component 520 cannot apply a pushing force to the child safety device 800.
[0131] In a preferred embodiment, the child protection component 800 of this disclosure can be driven by the child protection drive component 810 to move from the unprotected position to the protected position, and to hold the child protection component 800 in the protected position. Furthermore, the process of the child protection component 800 moving from the protected position to the unprotected position can be achieved by the restoring force of the return spring.
[0132] In a specific embodiment, such as Figure 10 As shown, the inward-opening manual unlocking component 520 includes a slot, and the child safety component 800 includes a corner portion. When the child safety component 800 is in the unlocked position, at least a portion of the corner portion is located in the slot, so that the child safety component and the inward-opening manual unlocking component rotate synchronously, thereby forming a stable force transmission connection between the inward-opening manual unlocking component and the intermediate transmission component 700 through the child safety component 800.
[0133] In one embodiment, the intermediate transmission component 700 is further configured to drive the locking component 600 from the locked position to the unlocked position. Specifically, the intermediate transmission component 700 may include an arm feature 710 capable of contacting a sidewall surface of the gear component 612 and applying a thrust to the gear component 612. Figure 10 As shown, when the intermediate transmission component 700 rotates clockwise, it can apply a thrust to the gear component 612 through the arm feature 710, causing the gear component 612 to rotate counterclockwise, so that the safety component 600 moves from the upper safety position to the unlocked position.
[0134] In general, the ability of the inward-opening manual unlocking component 520 to unlock the side door lock depends on the state of the child safety control component 800. Specifically, when the child safety control component 800 is in the engaged position, operating the inward-opening manual unlocking component 520 will not cause the intermediate transmission component 700 to rotate, and consequently, the side door lock cannot be unlocked. However, when the child safety control component 800 is in the disengaged position, regardless of whether the safety component is in the engaged or disengaged position, operating the inward-opening manual unlocking component 520 can unlock the side door lock. In other words, when the safety component is in the disengaged position, operating the inward-opening manual unlocking component 520 can directly unlock the side door lock. When the safety component is in the locked position, when the inward manual unlocking component 520 is operated, the intermediate transmission component 700 rotates together with the inward manual unlocking component 520. At the beginning of the rotation process, the intermediate transmission component 700 will drive the gear component 612 to rotate, so that the safety component is in the unlocked position. In the middle and end of the rotation process, the intermediate transmission component 700 will drive the transition component 500 to rotate, thereby unlocking the side door lock.
[0135] In a preferred embodiment, when the side door lock is applied to the driver's side door, it includes a lock cylinder assembly (not shown) that can be inserted with a key and turned. When the lock cylinder assembly is turned, it causes a lever assembly 900 to rotate. When the lever assembly 900 rotates, it drives a locking member 600 to reciprocate between a locked position and a unlocked position.
[0136] In other words, the side door lock disclosed herein can be locked using a key. It can also be unlocked using a key, and once unlocked, the side door can be unlocked by pulling the outward manual unlocking component.
[0137] In a preferred embodiment, the safety component 600 includes a protrusion feature, and the lever component 900 includes a groove feature, the two sidewalls of which can engage with the protrusion feature of the safety component 600 to drive the safety component 600 to rotate.
[0138] In this disclosure, the safety component 600 is also used to trigger the lock status signal switch 620. When the safety component 600 is in the unlocked state, the lock status signal switch 620 is triggered. Thus, when the side door lock of this disclosure is in use, the current state of the side door lock can be obtained according to the lock status signal switch 620 and the pawl signal switch 340.
[0139] In the various components of the side door lock disclosed herein, if a movement during its reciprocating motion is not driven by any component, then the reset force provided by the reset spring can cause it to perform a reset movement.
[0140] Figure 14 This is a structural schematic diagram of a side door lock according to another embodiment of the present disclosure.
[0141] like Figure 14 As shown, unlike the above implementation, in the side door lock of this embodiment, the intermediate transmission component 700 cannot drive the safety component from the upper safety position to the unlocked position. At this time, the inner manual unlocking component is used to drive the safety component from the upper safety position to the unlocked position.
[0142] like Figure 14 As shown, the internal manual unlocking assembly of this disclosure includes a drive feature 521 capable of contacting a sidewall surface of the gear component 612 and applying a thrust to the gear component 612. Specifically, with Figure 14 As shown, when the internal manual unlocking component rotates clockwise, it can apply a thrust to the gear component 612 through the drive feature 521, causing the gear component 612 to rotate counterclockwise, so that the safety component 600 moves from the upper safety position to the unlocked position.
[0143] Therefore, the side door lock disclosed herein can be unlocked by the cooperation of the inward-opening manual unlocking component and the outward-opening manual unlocking component, thus making the side door lock of this disclosure more secure.
[0144] In other words, regardless of the position and state of the child safety control component, when the inward-opening manual unlocking component is operated and rotated clockwise, the safety component 600 can move from the locked position to the unlocked position. At this time, when the child safety control component is in the unlocked position, the inward-opening manual unlocking component will be able to open the side door lock; when the child safety control component is in the locked position, the inward-opening manual unlocking component cannot open the side door lock, but the outward-opening manual unlocking component will be able to open the side door lock.
[0145] Figure 15 This is a schematic diagram of the pawl buffer block of a side door lock according to one embodiment of the present disclosure.
[0146] like Figure 15 As shown, the lock body 100 of this disclosure is also provided with a pawl buffer block 360. When the pawl component 310 is in the middle position and the stop position, the pawl buffer block 360 will contact the pawl component 310, thereby buffering the pawl component 310.
[0147] In other words, when the pawl component 310 is in the middle position, the pawl component 310 will compress the pawl buffer block 360. When the pawl component 310 moves from the middle position to the stop position, the pawl buffer block 360 will be further compressed. Thus, by setting the pawl buffer block 360, the noise of the pawl component 310 during movement can be reduced, and the user experience can be improved.
[0148] According to another aspect of this disclosure, a motor vehicle is provided, which includes the aforementioned side door lock.
