[0052] The present disclosure will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are merely exemplary and are not limiting to the present disclosure. In addition, it should also be understood that for the convenience and clarity of the description, only parts of the relevant are shown in the drawings.
[0053] It should be noted that the embodiments and features of the present disclosure can be combined if there is no conflict. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.
[0054] Unless otherwise specified, the exemplary embodiments / examples shown will be understood as providing exemplary features of various details that can implement the technical concepts of the present disclosure in practice. Therefore, unless otherwise specified, the features of various embodiments / examples can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.
[0055] In the drawings, cross-hatching and / or shading are generally used to indicate that a portion of one component is positioned above another component, or that the portion of one component is positioned below another component. As such, unless otherwise specified, the presence of cross-hatching or shading is not a requirement for any particular material, material property, size, proportion, commonality of the illustrated components, or any other characteristic, attribute, property, or the like of the components. In addition, the dimensions and the relative dimensions of the portions in the drawings are chosen primarily for convenience and clarity of presentation and are not necessarily shown to scale. When exemplary embodiments can be implemented differently, a specific process sequence can be performed in a different order than described. For example, two consecutively described processes can be performed substantially simultaneously or in reverse order to the described order. In addition, the same reference numbers represent the same components.
[0056] When a component is referred to as being “on” or “above” another component, “connected to” or “coupled to” another component, it can be directly on, directly connected to, or directly coupled to the other component, or intervening components can be present. However, when a component is referred to as being “directly on” or “directly connected to” or “directly coupled to” another component, there are no intervening components present. For this reason, the term “connected” can refer to a physical connection, an electrical connection, or the like, with or without intervening components.
[0057] For descriptive purposes, the present disclosure can use spatial or relative terms, such as "below," "lower," "lower than," "above," "upper," "higher," and the like, which can be understood as used in the context of the accompanying drawings. Spatial and / or relative terms are for purposes of illustration only and do not limit the scope of the application.

It is also noted that the terms "substantial," "approximately," and other similar terms, as used herein, are used in a relative sense and not in an absolute sense. Thus, they are used to explain approximations, measurement values, and / or provided values that a person of ordinary skill in the art would recognize as inherently having some error.
[0059] Figure 1 is a structural schematic diagram of a lock system according to an embodiment of the present disclosure. Figure 2 is an internal structural schematic diagram of a lock system according to an embodiment of the present disclosure. Figure 3 is a partial structural schematic diagram of a lock system according to an embodiment of the present disclosure.
[0060] As shown in Figures 1 to 3 , the lock system of the present disclosure can be applied to a side door of a vehicle and achieve locking and unlocking of the side door and the vehicle body. At this time, the lock system can also be referred to as a side door lock.
[0061] The lock system of the present disclosure can include a lock body 100, a latch member 200, a pawl assembly 300, and the like. In addition, the lock system of the present disclosure can also include an unlocking member and the like, and the unlocking of the lock system is achieved through the unlocking member. Since the unlocking member and the like can be implemented in the structure of the prior art, the present disclosure will not be described one by one.
[0062] The lock body 100 is used to house components such as the bolt assembly 200 and the pawl assembly 300. In use, the lock system of this disclosure can be fixed by fixing the lock body 100 to the sliding door of a motor vehicle.
[0063] In one specific embodiment, the lock body 100 may include components such as a base plate, and correspondingly, the bolt component 200 and the pawl assembly 300 are rotatably disposed on the base plate of the lock body 100.
[0064] Figure 4 This is a structural schematic diagram of the working state of a lock system according to one embodiment of the present disclosure.
[0065] The latch component 200 of this disclosure has a first rotation axis and a first locking position and a second locking position. The first locking position can be a fully locked position, in which the lock system is in a locked state, and the second locking position can be a partially locked position, in which the lock system is in a partially locked state. Additionally, the latch component 200 may also include an unlocked position, in which the lock system is in an unlocked state. In this unlocked position, the latch component 200 can release the latch and unlock the lock system of this disclosure.
[0066] In other words, when the latch component 200 is driven and rotated, the latch component 200 can move to one of the first locked position, the second locked position, and the unlocked position. For example, with Figure 4 As shown, when the latch member 200 rotates counterclockwise, it can move from the first locked position to the second locked position, and when the latch member 200 rotates further counterclockwise, it can move from the second locked position to the unlocked position, thereby unlocking the lock system. Conversely, when the latch member 200 rotates clockwise, it can move from the unlocked position to the second locked position, and when the latch member 200 rotates further clockwise, it can move from the second locked position to the first locked position, thereby locking the lock system of this disclosure.
[0067] In one specific embodiment, the counterclockwise rotation of the latch component 200 can be achieved by the restoring force provided by a component such as a return spring, while the clockwise rotation of the latch component 200 can be driven by an electric locking device to achieve electric locking of the lock system of this disclosure. The electric locking device of this disclosure can be implemented using solutions in the prior art, which will not be described in detail here.
[0068] like Figure 3 and Figure 4As shown, the pawl assembly 300 of this disclosure includes a first pawl 310, a second pawl 320, and a sliding pawl 330. The first pawl 310 is used to restrict the latch member 200 to a first locked position, and the second pawl 320 is used to restrict the latch member 200 to a second locked position. The sliding pawl 330 is used to restrict the position of the first pawl 310 so that the first pawl 310 can restrict the latch member 200 to the first locked position. The sliding pawl 330 can be driven by the second pawl 320, causing the sliding pawl 330 to release the first pawl 310.
[0069] In some embodiments of this disclosure, the first pawl 310 has a first locking surface 311 and a first feature portion 312. The first locking surface 311 is used to engage with the first locking position (first locking surface) of the latch member 200 to lock the latch member 200 in the first locking position (fully locked position). The first feature portion 312 is used to cooperate with the sliding pawl 330, in which case the sliding pawl 330 pushes the first pawl 310 by pushing the first feature portion 312 to release the engagement of the first pawl 310 with the first locking position of the latch member 200, thereby unlocking the lock system.
[0070] The second pawl 320 has a second locking surface 321, a first groove feature 322, and a second groove feature 323. The second locking surface 321 is used to engage with the second locking position (the column structure on the latch member 200) of the latch member 200, locking the latch member 200 in the second locking position (half-locked position). The first groove feature 322 is set as an arc-shaped groove, and the rotation axis of the first pawl 310 is slidably disposed within the first groove feature 322. That is to say, through the setting of the first groove feature 322, the rotation axis of the first pawl 310 will not affect the rotation of the second pawl 320.
[0071] The second groove feature 323 is used to drive the sliding pawl 330 to slide out from between the first pawl 310 and the limiting member 340.
[0072] The sliding pawl 330 disclosed herein includes a shaft feature 331, wherein the shaft feature 331 is slidably and rotatably disposed in the second groove feature 323 of the second pawl 320, and the second pawl 320 drives the shaft feature 331 through the second groove feature 323, so that the sliding pawl 330 can slide out from between the first pawl 310 and the limiting member 340.
[0073] Meanwhile, the shaft feature 331 of the sliding pawl 330 can cooperate with the first feature 312 of the first pawl 310 to push the first feature 312 of the first pawl 310 and release the engagement of the first pawl 310 with the first locking position of the locking tongue component 200.
[0074] The reverse movement of the various components of the pawl assembly 300 of the present disclosure can be accomplished by the return force provided by the return spring, which will not be described again in detail by the present disclosure.
[0075] The lock system of the present disclosure further comprises a point detonator 400, which is a device that works in the event of a vehicle collision, etc., wherein the mover 410 of the point detonator 400 is used to generate linear motion when the point detonator 400 works. The point detonator 400 can be implemented by using products in the prior art, which will not be described again in detail by the present disclosure.
[0076] When the point detonator 400 works, the mover 410 of the point detonator 400 is used to push the lock tongue component 200 to rotate in the direction of the unlocking position.
[0077] That is to say, when the vehicle collides, the pawl assembly 300 will unlock the lock tongue component 200, and under normal circumstances, the lock tongue component 200 will move to the unlocking position under the action of the return spring; when the lock tongue component 200 is deformed and cannot move to the unlocking position, the driving force provided by the point detonator 400 can push the lock tongue component 200 from the full lock position or the half lock position to a position outside the half lock position, realizing the opening function of the vehicle door.
[0078] That is to say, when the point detonator 400 of the present disclosure works, it can push the lock tongue component 200 to move to the unlocking position and pass the half lock position.
[0079] The point detonator 400 of the present disclosure can be fixed on the bottom plate of the lock body 100 by a fixing frame and arranged inside the lock body 100.
[0080] In one embodiment, as shown in Figure 3 and Figure 4 The lock system of the present disclosure further comprises a push rod component 500, which has a second rotation axis, the point detonator 400 is used to push the push rod component 500 to rotate, and the push rod component 500 is used to push the lock tongue component 200 to rotate.
[0081] That is to say, the point detonator 400 of the present disclosure can directly push the lock tongue component 200 to rotate in the unlocking direction, or indirectly push the lock tongue component 200 to rotate in the unlocking direction through the push rod component 500.
[0082] In a preferred embodiment, the first rotation axis is parallel to the second rotation axis.
[0083] The lock system of the present disclosure further comprises an ice-breaking pull rod 600, which has the same rotation axis as the push rod component 500. At this time, when the ice-breaking pull rod 600 rotates, it can drive the lock bolt component 200 to rotate in the unlocking direction, so that when the lock bolt component 200 cannot be opened under the resetting force of the resetting spring after the vehicle is covered with ice and snow, the ice-breaking pull rod 600 can be pulled to make the lock bolt component 200 rotate in the unlocking direction, thereby breaking the ice and snow covering the outside of the vehicle.
[0084] That is, when the lock system does not comprise the ice-breaking pull rod 600, the push rod component 500 can be rotatably arranged on the lock body 100; when the lock system comprises the ice-breaking pull rod 600, the push rod component 500 and the ice-breaking pull rod 600 can be mounted on the same shaft component 550.
[0085] In the present disclosure, when the lock system comprises the ice-breaking pull rod 600, the push rod component 500 is used to push the ice-breaking pull rod 600 to rotate, and the ice-breaking pull rod 600 is used to push the lock bolt component 200 to rotate. Of course, the push rod component 500 of the present disclosure can also not push the ice-breaking pull rod 600 to rotate, but rotate independently and push the lock bolt component 200 to rotate.
[0086] Figure 5 And Figure 6 is a structural schematic view of a push rod assembly according to an embodiment of the present disclosure.
[0087] The push rod component 500 comprises fin parts 510, force receiving parts 520, force applying parts 530, and stop parts 540, etc.
[0088] The fin parts 510 of the present disclosure are generally formed as sheet-shaped parts and are arranged as two. Both of the two fin parts 510 are provided with through holes, and the shaft component 550 is arranged in the through holes, wherein the fin part 510 is arranged to be rotatable relative to the shaft component 550.
[0089] Moreover, the two fin parts 510 are arranged in parallel, and correspondingly, the two fin parts 510 are located at different positions in the axial direction of the shaft component 550. Taking the example that the shaft component 550 is arranged vertically, the fin part 510 is arranged generally horizontally. Among them, the two fin parts 510 can be connected through a connecting part, so that the distance between the fin parts 510 can be maintained.
[0090] The force receiving part 520 is connected to the fin part 510, wherein the force receiving part 520 is used to cooperate with the detonator 400 to receive the force applied by the detonator 400 to the push rod component 500. The force receiving part 520 of the present disclosure is formed as a vertically arranged plate-shaped structure, so that the force receiving part 520 has a larger contact area, thereby facilitating the receiving of the thrust applied by the detonator 400.
[0091] The force-applying part 530 is connected to the fin part 510 and the force-receiving part 520 so that the locking tongue part 200 is rotated through the contact between the force-applying part 530 and the locking tongue part 200.
[0092] In addition, such as Figure 7 As shown, the stop portion 540 is connected to the fin portion 510, and a spring 700 is provided between the stop portion 540 and the ice-breaking lever 600. The restoring force provided by the spring 700 keeps the push rod component 500 in its initial position. Specifically, the push rod component 500 can be restricted in position by, for example, the lock body 100, and the restoring force of the spring 700 keeps the push rod component 500 in its initial position. In this initial position, there is a gap between the push rod component 500 and the detonator 400. In one specific embodiment, the spring 700 can be a torsion spring, such as a double-wire torsion spring, which has a first part and a second part with different directions of rotation. Accordingly, one end of the first part and one end of the second part are connected to each other, and the connection is located in the middle of the double-wire spring. At this time, the connection between the first part and the second part of the double-wire spring is restricted in position, and the other end of the first part is in pressure contact with the stop 540, and the other end of the second part is connected to the ice-breaking lever 600. Thus, in the locking system of this disclosure, a spring can simultaneously provide a restoring force to the push rod component 500 and the ice-breaking lever 600.
[0093] Although the push rod component 500 of this disclosure is described using multiple components, this is merely for ease of description and does not imply that the push rod component 500 is formed separately and assembled together. In a preferred embodiment of this disclosure, the push rod component 500 is integrally formed.
[0094] When the lock system disclosed herein does not require emergency door opening due to a collision, after the pawl assembly is opened, only the ice-breaking lever can work normally. After unlocking, if the bolt component has not sprung out beyond the half-lock position, the ice-breaking lever can be used to push the bolt out beyond the half-lock position to open the door. When an emergency door opening command is issued due to a door collision, the ignition device is activated. The ignition device pushes the push rod component through its mover to push the bolt component out beyond the half-lock position, thereby enabling emergency door opening.
[0095] According to another aspect of this disclosure, a motor vehicle is provided, which includes the aforementioned side door lock.
