[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Figure 1 This is a schematic diagram of a side door lock according to one embodiment of the present disclosure.

[0073] like Figure 1 As shown, the side door lock disclosed herein may include components such as a lock body 100, a bolt component 200, a pawl assembly 300, and an electric unlocking assembly 400.

[0074] 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.

[0075] 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.

[0076] The locking tongue component 200 and the pawl assembly 300 disclosed herein can be implemented using solutions in the prior art, such as the structure described in publication number CN119466451A. Here, the structure of the locking tongue component 200 and the pawl assembly 300 will not be described in detail.

[0077] Figure 2 This is a schematic diagram of a side door lock according to one embodiment of the present disclosure.

[0078] like Figure 2 As shown, the electrically operated unlocking assembly 400 of this disclosure is used to cooperate with the pawl assembly 300 so that the pawl assembly 300 can release the latch member 200.

[0079] Specifically, the electrically operated unlocking assembly 400 disclosed herein includes a first motor 410 and a worm gear assembly 420 that is driveably connected to the first motor 410. The worm gear assembly 420 includes a cam that can drive an operating lever component 430 to rotate. When the operating lever component 430 rotates, it can push the pawl assembly 300 to actuate, thereby unlocking the side door lock.

[0080] The structure of the operating lever component 430 of this disclosure can be the same as that of the operating lever component described in disclosure number CN119466451A, and this disclosure will not repeat the details.

[0081] See again Figure 2 The side door lock disclosed herein may further include an outward-opening manual unlocking component 500, which engages with a ratchet assembly 300 to release the latch member 200. Specifically, as Figure 2As shown, the outward-opening manual unlocking assembly 500 includes components such as 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 generate a clockwise rotation (to...). Figure 2 (In the direction shown). The outward-opening drive rod 520 is rotatably disposed on the lock body 100, and one end of the outward-opening drive rod 520 is engaged with the other end of the outward-opening pull rod 510. Thus, when the outward-opening pull rod 510 rotates clockwise, it can drive the outward-opening drive rod 520 to rotate counterclockwise.

[0082] The disclosed external manual unlocking assembly 500 also includes an external opening safety link 530, which is driven to move between an active position and a deactivated position. When the external opening safety link 530 is in the active position, the external opening lever 510 is rotated, which drives the pawl assembly 300 to unlock the side door lock. Specifically, the rotation of the external opening lever 510 causes the external opening transmission rod 520 to rotate. At this time, the external opening transmission rod 520 applies a thrust to the external opening safety link 530. This thrust is transmitted to the operating lever component 430, causing the operating lever component 430 to rotate clockwise. As a result, the operating lever component 430 pushes the pawl assembly 300, thereby unlocking the side door lock.

[0083] On the other hand, when the outward opening safety linkage 530 is in the ineffective position, when the outward opening pull rod 510 is rotated, the end of the outward opening safety linkage 530 near the outward opening pull rod 510 is outside the envelope of the rotation process of the outward opening transmission rod 520. At this time, the outward opening transmission rod 520 is in an idle state, that is, the outward opening transmission rod 520 cannot apply a thrust to the outward opening safety linkage 530, and accordingly will not drive the pawl assembly 300 to move and unlock the side door lock.

[0084] In this disclosure, Figure 2 As shown, when the outward-opening safety linkage 530 moves to the right to its maximum position, the outward-opening safety linkage 530 is in the active position; conversely, when the outward-opening safety linkage 530 moves to the left to its maximum position, the outward-opening safety linkage 530 is in the inactive position.

[0085] Figure 3 This is a schematic diagram of a partial structure of a side door lock according to one embodiment of the present disclosure.

[0086] like Figure 2 and Figure 3As shown, the disclosed inward-opening manual unlocking assembly includes components such as an inward-opening lever 910 and an inward-opening safety linkage 930. The inward-opening lever 910 can be connected to the inward-opening handle of the side door via a cable, etc., and when an occupant operates the inward-opening handle of the side door, the inward-opening lever 910 can be rotated. Figure 2 As shown in the attached diagram, the inward-opening pull rod 910 can rotate clockwise.

[0087] The inward-opening safety linkage 930 is driven to move between an active position and a deactivated position. When the inward-opening safety linkage 930 is in the active position, the inward-opening pull rod 910 is rotated, which drives the pawl assembly 300 to actuate. That is, the inward-opening pull rod 910 can apply a thrust to the inward-opening safety linkage 930, which can push the operating lever component 430 to rotate.

[0088] When the inward-opening safety linkage 930 is in the ineffective position, when the inward-opening pull rod 910 is rotated, it will not drive the pawl assembly 300 to move; at this time, the inward-opening pull rod 910 will spin freely. Furthermore, with Figure 2 As shown, when the inward-opening safety linkage 930 moves to the right to its maximum position, the inward-opening safety linkage 930 is in the active position; conversely, when the inward-opening safety linkage 930 moves to the left to its maximum position, the inward-opening safety linkage 930 is in the inactive position.

[0089] Figure 4 This is a schematic diagram of the structure of a safety lever and central control assembly according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of a safety lever in a first position according to one embodiment of the present disclosure. Figure 6 This is a schematic diagram of the structure of a safety lever in a second position according to one embodiment of the present disclosure.

[0090] like Figures 1 to 6 As shown, the side door lock of this disclosure also includes a safety lever 600 and a central locking assembly 700, wherein the safety lever 600 is configured to rotate and has a first position and a second position; Figure 2 As shown, when the safety lever 600 rotates counterclockwise and is in its maximum position, it is in the first position; conversely, when the safety lever 600 rotates clockwise and is in its maximum position, it is in the second position.

[0091] The central control component 700 disclosed herein is used to drive the safety lever 600 to rotate. When the safety lever 600 is in the first position, the inward-opening manual unlocking component 500 and the outward-opening manual unlocking component 500 are allowed to drive the pawl assembly 300 to move and release the locking tongue component. When the safety lever 600 is in the second position, the inward-opening manual unlocking component 500 and the outward-opening manual unlocking component 500 are not allowed to drive the pawl assembly 300 to move.

[0092] In other words, through the settings of the central control component 700, regardless of the state of the inward-opening manual unlocking component 500 and the outward-opening manual unlocking component 500, both components can be locked, preventing the side door lock from being opened using either. Furthermore, the central control component 700 can directly drive the outward-opening manual unlocking component 500, disarming it. In this state, the side door lock can be unlocked by operating the outward-opening handle.

[0093] In other words, when the safety lever 600 is in the first position, the outward-opening manual unlocking component 500 is in the unlocked state; however, whether the inward-opening manual unlocking component is in the unlocked state depends on the position of the child safety lever 800, which will be explained in detail below.

[0094] like Figure 2 As shown, the central control assembly 700 of this disclosure includes a central control motor 710 and a central control worm gear 720; a central control worm is mounted on the output shaft of the central control motor 710; the central control worm gear 720 cooperates with the central control worm to enable the central control motor 710 to drive the central control worm gear 720 to rotate, and drive the safety lever 600 to rotate through the hollow worm gear.

[0095] In one embodiment, the central control worm gear 720 includes an active toothed portion, and the safety lever 600 includes a driven toothed portion. The active toothed portion and the driven toothed portion cooperate, so that when the central control worm gear 720 rotates, the safety lever 600 can be rotated through the gear transmission structure.

[0096] In another embodiment, one of the central control worm gear 720 and the safety lever 600 is provided with a shift fork, and the other is provided with a shift fork groove. The shift fork is movably (or slidably) disposed in the shift fork groove. When the central control worm gear 720 rotates, the safety lever 600 can be rotated through the shift fork drive.

[0097] In another embodiment, the central control worm gear 720 includes a pushing part, which is used to push the safety lever 600 from a first position to a second position, and to reset the safety lever 600 from the second position to the first position by means of a return spring; or, the pushing part is used to push the safety lever 600 from the second position to the first position, and to reset the safety lever 600 from the first position to the second position by means of a return spring.

[0098] Figure 7 This is a schematic diagram of the child safety lever in the child safety release position according to one embodiment of the present disclosure. Figure 8 This is a schematic diagram of the pediatric safety lever in the upper pediatric safety position according to one embodiment of the present disclosure. Figure 9This is a schematic diagram of the structure of a child safety lever according to one embodiment of the present disclosure. Figure 10 This is a schematic diagram illustrating the cooperation relationship between the child safety lever and the inward-opening safety linkage according to one embodiment of this disclosure.

[0099] like Figures 7 to 10 As shown, the side door lock of this disclosure also includes a child safety lever 800, which is used to drive the inward opening safety linkage 930 to move from the active position to the inactive position.

[0100] In other words, the inward-opening safety linkage 930 can be driven by both the safety lever 600 and the child safety lever 800 to move from the active position to the inactive position.

[0101] Specifically, the child safety lever 800 of this disclosure can be manually operated and rotated. In a preferred embodiment, the child safety lever 800 and the central locking worm gear share the same axis of rotation, thereby enabling the side door lock of this disclosure to have a high degree of integration and a small size. In other words, the child safety lever 800 and the central locking worm gear can be positioned by the same positioning post on the cover plate (set on the cover plate of the lock body 100), with the child safety lever on the lower layer and the central locking worm gear on the upper layer. For better noise reduction, a sound-absorbing sleeve can be added to the child safety lever to reduce noise between the cover plate and the child safety lever.

[0102] by Figure 7 and Figure 8 As shown, when the child safety lever 800 is rotated counterclockwise and reaches its maximum position, the child safety lever 800 is in... Figure 7 The child safety interlocking lever 930 is in the activated position when the interlocking lever 800 is in the off position. Conversely, when the interlocking lever 800 rotates clockwise and reaches its maximum position, the interlocking lever 800 is in the off position. Figure 8 The upper child safety position is shown, at which point the inner opening safety linkage 930 is in the inactive position.

[0103] The following will explain the combination of the child safety lever 800 and the safety lever 600 in different situations.

[0104] When the child safety lever is at 800 Figure 7 When the safety lever 600 is in the first position, as shown in the diagram, both the inward-opening manual unlocking component and the outward-opening manual unlocking component 500 can open the side door lock.

[0105] When the child safety lever 800 is in the child safety release position and the safety lever 600 is in the second position, neither the inward-opening manual unlocking component nor the outward-opening manual unlocking component 500 can open the side door lock.

[0106] When the child safety lever 800 is in the upper child safety position and the safety lever 600 is in the first position, the outward-opening manual unlocking component 500 can open the side door lock, while the inward-opening manual unlocking component cannot open the side door lock.

[0107] When the child safety lever 800 is in the upper child safety position and the safety lever 600 is in the second position, neither the inward-opening manual unlocking component nor the outward-opening manual unlocking component 500 can open the side door lock.

[0108] In this disclosure, the inward-opening safety link 930 can be moved from a failed position to an active position by the restoring force of the return spring 810. For example, the safety lever 600 includes a pushing structure that cooperates with the inward-opening safety link 930 to push the inward-opening safety link 930 from the active position to the failed position. When the safety lever 600 rotates in the reverse direction, the inward-opening safety link 930 will be able to move from the failed position to the active position under the action of the return spring 810.

[0109] In a preferred embodiment, the child safety lever 800 is provided with an arc-shaped groove, and one end of the inner opening safety linkage 930 can slide in the arc-shaped groove. Thus, when the child safety lever 800 is in the child safety unlock position, the inner opening safety linkage 930 can be driven to move and realize the locking of the inner opening manual unlocking component.

[0110] In this disclosure, the safety lever 600 is used to drive the outward-opening safety linkage 530 to move between the active position and the inactive position. Furthermore, this structure can be implemented using the structure described in disclosure number CN119466451A, which will not be elaborated upon here.

[0111] For side door locks such as the front side doors of a vehicle that do not have child safety features, the child safety lever can be removed, and a guide structure can be made directly on the cover plate, which can also achieve the function of the central control component.

[0112] According to another aspect of this disclosure, a motor vehicle is provided, which includes the aforementioned side door lock.
