Description

Technical Field

[0001] This invention relates to the field of vehicle door lock technology, specifically to an emergency unlocking and stopping device, a door lock assembly, a vehicle door, and a vehicle. Background Technology

[0002] With the rapid development of my country's automobile industry, automobiles have gradually become a common means of transportation in our daily lives. To prevent danger caused by car doors opening while the car is in motion, locking and unlocking devices are usually installed on the door locks. While the car is in motion, the locking device can be used to lock the door to prevent it from opening. When it is necessary to open the door, the unlocking device can be used to unlock the door to facilitate opening.

[0003] With the increase in car use, car collisions are also occurring frequently. When a car collision occurs, it is necessary to open the car door to rescue the people inside. In order to avoid the car door being unable to be opened from the outside during rescue, cars are usually equipped with an automatic unlocking and stopping function. When a car collision occurs, the unlocking and stopping device can be controlled to automatically unlock the car door so that rescuers can rescue the people inside the car.

[0004] However, currently, the automatic unlocking of car doors during a collision is usually achieved by the vehicle's body control system receiving a collision verification signal, then energizing the door locks to unlock them. Alternatively, occupants can manually unlock the doors. However, this method is ineffective if a collision causes a power outage and the occupants lose their ability to move freely. In such cases, the door locks must be damaged to rescue the occupants, increasing repair costs. Summary of the Invention

[0005] This application provides an emergency unlocking and stopping device, a door lock assembly, a vehicle door, and a vehicle, to at least solve the technical problem in related technologies where the vehicle door cannot be unlocked or stopped when the vehicle experiences a power outage and the occupants lose their autonomy. The technical solution adopted by this invention is as follows:

[0006] According to a first aspect of this application, an emergency unlocking and stopping device is provided, applied to a vehicle door lock assembly. The emergency unlocking and stopping device includes a fixed base, a first elastic member, a rotating member, and an inertial member. The first elastic member is connected to the fixed base. The rotating member is connected to the first elastic member and rotatably connected to the fixed base, and is capable of rotating around a first axis between a first position and a second position. The rotating member has a pulling part eccentrically disposed relative to the first axis, and the pulling part is used to connect to a safety pin of the door lock assembly. When the rotating member is in the first position, it compresses the first elastic member to a compressed state, and the safety pin locks the vehicle door. When the rotating member is in the second position, it releases the first elastic member to a free state, and the safety pin unlocks the door. The inertial member is connected to the fixed base and is capable of moving from a third position to a fourth position under the action of inertia. When the inertial member is in the third position, it abuts against the rotating member to limit the rotating member to the first position. When the inertial member is in the fourth position, it releases the abutment against the rotating member, allowing the rotating member to rotate from the first position to the second position under the action of the first elastic member.

[0007] According to the above technical means, the first elastic element is connected to the fixed seat and the rotating element. The rotating element can rotate between the first position and the second position. The inertial element is connected to the fixed seat and can move from the third position to the fourth position under the action of inertia. When the rotating element is in the first position, it compresses the first spring to the compressed state, and the safety pin locks the door. At this time, the inertial element is in the third position and abuts against the rotating element, thereby limiting the rotating element to the first position.

[0008] When a vehicle collides, the inertial component moves from the third position to the fourth position under the action of inertia. At this time, the inertial component releases the restriction on the rotating component. Under the action of the first elastic component, the rotating component will rotate from the first position to the second position. During the process of the rotating component rotating from the first position to the second position, the pulling part will generate a pulling force on the safety pin of the door lock assembly, thereby pulling the safety pin to move. When the first elastic component is released to its natural state, the rotating component rotates to the second position. At this time, the pulling part pulls out the safety pin, thereby releasing the safety pin from locking the door.

[0009] By coordinating the inertial and rotating components, when a vehicle collision causes a power outage and the occupants lose their autonomy, the inertial component automatically rotates due to inertia, causing the rotating component to rotate and unlock the door. This allows the door to be opened from the outside for rescue of the occupants. Furthermore, the rescue process does not require damaging the door lock, and the door lock does not need to be repaired during vehicle maintenance, thus reducing maintenance costs.

[0010] In one possible implementation, the inertial component includes an inertial lock and a blocking boss. The inertial lock is rotatably connected to the fixed base and is capable of rotating from a third position to a fourth position around a second axis under the action of inertia. The blocking boss is fixed to the inertial lock and is located on the side of the second axis closer to the rotating component. When the inertial lock is in the third position, the blocking boss abuts against the rotating component. When the inertial lock is in the fourth position, the blocking boss releases its abutment against the rotating component.

[0011] Based on the above-mentioned technical means, by rotating the inertial lock from the third position to the fourth position, the structure of each component in the door lock assembly can be made more compact, thereby making effective use of space.

[0012] In one possible implementation, the rotating member includes a rotating shaft and a limiting block. The rotating shaft is rotatably connected to the fixed base and can rotate about its axis. The axial direction of the rotating shaft is consistent with the height direction of the vehicle. The limiting block is fixed to the rotating shaft and has a pulling part formed on it. When the inertia lock is in the third position, the limiting block and the blocking boss are arranged in sequence and abut against each other in the direction of rotation of the rotating member from the first position to the second position. When the inertia lock is in the fourth position, the blocking boss is located on the side of the limiting block closer to the inertia member.

[0013] According to the above-mentioned technical means, by blocking the boss to abut against the rotating part in the direction of the rotating part's rotation from the first position to the second position, the rotating part can be effectively confined to the first position, thereby improving the confining effect on the rotating part.

[0014] In one possible implementation, the blocking boss has a first guiding arc surface and a clearance notch on the side near the rotating member. Along the direction of rotation of the inertial lock from the third position to the fourth position, the clearance notch and the first guiding arc surface are arranged in sequence. During the rotation of the inertial lock from the third position to the fourth position, the blocking boss pushes the limiting block in the direction from the second position to the first position, and the first guiding arc surface can slide relative to the limiting block. When the inertial lock rotates to the fourth position, at least a portion of the limiting block is located in the clearance notch, and the rotating member rotates from the first position to the second position.

[0015] According to the above technical means, the first guiding arc surface can make the inertial lock move more smoothly from the third position to the fourth position under the action of inertia. By avoiding the gap, when the inertial lock rotates to the fourth position, it will no longer interfere with the rotating part, so that the rotating part can smoothly rotate from the first position to the second position, thereby enabling the emergency unlocking and stopping device to work effectively.

[0016] In one possible implementation, a limiting boss is formed on the inertial component, and a limiting component is provided on the fixed base. The limiting component and the limiting boss are arranged in sequence along the direction in which the inertial component rotates from the third position to the fourth position. When the inertial component is in the third position, the limiting component abuts against the limiting boss to limit the inertial component to be in the third position.

[0017] According to the above technical means, by abutting the limiting member with the limiting boss, the inertial member can be limited, so as to prevent the inertial member from rotating under the action of the rotating member and the first elastic member, thereby avoiding affecting the stability of the emergency unlocking and stopping device.

[0018] In one possible implementation, the inertial member further includes a second elastic member, which is connected to the fixed base and to the inertial member, for moving the inertial member from the fourth position to the third position; when the inertial member is in the third position, the second elastic member is in a natural state, and when the inertial member is in the fourth position, the second elastic member is compressed.

[0019] Based on the above technical means, the inertial component can be quickly reset by the second elastic element, which improves the ease of operation of the emergency unlocking and stopping device.

[0020] In one possible implementation, the first elastic element includes a first torsion spring, the axis of which coincides with the first axis, and one torsion arm of the first torsion spring is connected to a fixed base, and the other torsion arm of the first torsion spring is connected to a rotating element; and / or, the second elastic element includes a second torsion spring, the axis of which coincides with the second axis, and one torsion arm of the second torsion spring is connected to a fixed base, and the other torsion arm of the second torsion spring is connected to an inertial element.

[0021] Based on the above technical means, the first torsion spring can make the rotating part more uniformly stressed during rotation, thus making the rotation of the rotating part more stable and smoother; the second torsion spring can make the inertial part more uniformly stressed during rotation, thus making the rotation of the inertial part more stable and smoother.

[0022] According to a second aspect of this application, a door lock assembly is provided, including a base, the aforementioned emergency unlocking and stopping device, a first pull cable, and a safety pin. A first sliding hole extending along the length of the vehicle body is formed on the base. A fixing seat for the emergency unlocking and stopping device is engaged with the base. One end of the first pull cable is connected to a pulling part, and the other end of the first pull cable passes through the first sliding hole, and the first pull cable is slidable relative to the first sliding hole. The safety pin is located on one side of the base along the length of the vehicle and is connected to the other end of the first pull cable. The safety pin is used to lock the vehicle door. During the rotation of a rotating member from a first position to a second position, the pulling part pulls the first pull cable to slide, causing the first pull cable to pull the safety pin to move, thereby unlocking the door.

[0023] In one possible implementation, the door lock assembly further includes a stop button rotatably connected to the base. The rotation axis of the stop button is aligned with the height direction of the vehicle. The stop button is connected to one end of a first cable and is used to pull the first cable to move, thereby causing the first cable to pull the safety pin to move.

[0024] In one possible implementation, the rotation axis of the stop button coincides with the first axis; the rotating member has a circumferentially extending clearance portion around the first axis, the clearance portion having a starting end and a ending end, the starting end and the ending end being arranged sequentially along the direction of rotation of the rotating member from the first position to the second position, and the pull portion being located at the starting end; the door lock assembly also includes a first connecting rod, one end of the first connecting rod being connected to the stop button, the other end of the first connecting rod being slidably connected to the clearance portion, and one end of the first pull cable being connected to the first connecting rod; rotation of the stop button can drive the first connecting rod to slide between the starting end and the ending end, during the rotation of the rotating member from the first position to the second position, the first connecting rod is located at the starting end and abuts against the pull portion.

[0025] In one possible implementation, the base is further provided with a second sliding hole extending along the length of the vehicle body; the door lock assembly also includes an unlocking component, which includes a handle, a second cable, and a latch. The handle is rotatably connected to the base, and the axis of rotation of the handle is aligned with the height direction of the vehicle body; one end of the second cable is connected to the handle and is eccentrically positioned relative to the axis of rotation of the handle, and the other end of the second cable passes through the second sliding hole, and the second cable is slidable relative to the second sliding hole; the latch is located on one side of the base and is connected to the other end of the second cable, and the latch is used to close the vehicle door.

[0026] According to a third aspect provided in this application, a vehicle door is provided, including a door body and the aforementioned door lock assembly, the door lock assembly being disposed on the door body.

[0027] According to the fourth aspect provided in this application, a vehicle is provided, including the aforementioned door.

[0028] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0029] (1) The present invention, through the cooperation of an inertial component, a rotating component and a first elastic component, when a vehicle collision causes the entire vehicle to lose power and the occupants lose their autonomy, the inertial component can automatically rotate under the action of inertia, thereby causing the rotating component to rotate and drive the safety pin to unlock the door, so that the door can be opened from the outside of the vehicle to facilitate the rescue of the occupants. Furthermore, the rescue process does not require damage to the door lock, and the door lock does not need to be repaired during car repair, thereby reducing maintenance costs.

[0030] (2) The present invention uses an inertial lock to rotate and connect to a fixed base, so that the inertial lock can move from the third position to the fourth position, which can make the structure of each component in the door lock assembly more compact, thereby making effective use of space.

[0031] (3) By blocking the boss to abut against the rotating part in the direction of the rotating part rotating from the first position to the second position, the present invention can effectively limit the rotating part to the first position and improve the limiting effect on the rotating part.

[0032] (4) The present invention allows the inertial lock to move more smoothly from the third position to the fourth position under the action of inertia through the first guiding arc surface. By avoiding the gap, the rotating part will no longer be interfered with when the inertial lock rotates to the fourth position, so that the rotating part can smoothly rotate from the first position to the second position, thereby enabling the emergency unlocking and stopping device to work effectively.

[0033] (5) The present invention can limit the inertial component by abutting the limiting component with the limiting boss, thereby preventing the inertial component from rotating under the action of the rotating component and the first elastic component, thus avoiding affecting the stability of the emergency unlocking and stopping device.

[0034] (6) The present invention enables the inertial component to be quickly reset by the second elastic element, thereby improving the ease of operation of the emergency unlocking and stopping device.

[0035] (7) The present invention can make the rotating part more uniformly stressed during rotation by using the first torsion spring, thereby making the rotation of the rotating part more stable and smoother; the second torsion spring can make the inertial part more uniformly stressed during rotation, thereby making the rotation of the inertial part more stable and smoother.

[0036] It should be noted that the technical effects of any of the implementation methods in the second to fourth aspects can be found in the technical effects of the corresponding implementation methods in the first aspect, and will not be repeated here.

[0062] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0063] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0064] Car door locks are usually equipped with locking and unlocking devices. While the car is in motion, the locking device can be used to lock the door to prevent it from opening and causing danger. When it is necessary to open the door, the unlocking device can be used to unlock the door so that it can be opened.

[0065] However, current car unlocking devices typically receive collision verification signals from the vehicle's body control system and then energize the door locks based on these signals, thereby controlling the unlocking device to unlock the doors. Alternatively, occupants can manually control the unlocking device to unlock the doors. However, if a collision causes a power outage and the occupants lose their ability to move freely, the unlocking device cannot be controlled to unlock the doors, preventing them from being opened from the outside. Rescuing the occupants would require damaging the door locks, necessitating lock repair during vehicle maintenance and increasing repair costs.

[0066] This application provides a vehicle that can be an electric vehicle, a hybrid electric vehicle, a methanol vehicle, a gasoline vehicle, etc.

[0067] For ease of understanding, the vehicle provided in this application will be described in detail below with reference to the accompanying drawings.

[0068] The vehicle includes doors and a body. The doors are connected to the body and can be front doors, rear doors, or a tailgate. Each door includes a door body and a door lock assembly. The door lock assembly is located on the door body. In the following description, taking the front door as an example, the door lock assembly is located on the door body and is connected to the B-pillar of the body to achieve the closing and locking of the door. The door lock assembly is disconnected from the B-pillar of the body to achieve the opening and unlocking of the door.

[0069] Figure 1 This is one of the structural schematic diagrams of a door lock assembly according to an exemplary embodiment, such as... Figure 1 As shown, the door lock assembly includes a base 1 and an unlocking component 2. The base 1 is fixed to the car door, and the unlocking component 2 is connected to the base 1. The unlocking component 2 is used to close and open the car door.

[0070] The unlocking assembly 2 includes a handle 21, which is rotatably connected to the base 1. The axis of rotation of the handle 21 is aligned with the height direction of the vehicle body. Specifically, a fixed shaft 11 extending along the height direction of the vehicle body can be provided on the base 1, and the handle 21 can be rotatably connected to the fixed shaft 11, allowing the handle 21 to rotate around the fixed shaft 11. Alternatively, a bearing can be provided on the base 1, and a rotating shaft extending along the height direction of the vehicle body can be provided on the handle 21. The rotating shaft is connected to the bearing, and the handle 21 can rotate around its axis by rotating the rotating shaft.

[0071] In the following description, we will take as an example a fixed shaft 11 extending along the height direction of the vehicle body is provided on the base 1, the handle 21 is rotatably connected to the fixed shaft 11, and the handle 21 can rotate around the fixed shaft 11.

[0072] Figure 2 This is a second schematic diagram of a door lock assembly according to an exemplary embodiment, as shown below. Figure 2 As shown, a second sliding hole 12 extending along the length of the vehicle body is formed on the base 1. Specifically, a second locking rod is formed on the side of the base 1 near the B-pillar of the vehicle body, and the second sliding hole 12 is formed on the second locking rod.

[0073] The unlocking assembly 2 also includes a second cable 22 and a latch (not shown in the figure), with the latch located on one side of the base 1. Specifically, taking the front door rotating around the A-pillar of the vehicle body as an example, when the door is closed, the latch is located on the side of the base 1 closer to the B-pillar of the vehicle body; taking the door lock assembly located on the trunk door as an example, when the trunk door rotates around an axis extending along the height direction of the vehicle body, the latch can be located on one side of the base 1 in the width direction of the vehicle body, and when the trunk rotates around an axis extending along the width direction of the vehicle body, the latch can be located on one side of the base 1 in the height direction of the vehicle body.

[0074] The latch is used to close the vehicle doors. Specifically, taking the front door rotating around the A-pillar of the vehicle body as an example, after the latch extends into the lock hole in the B-pillar of the vehicle body, the connection between the latch and the lock hole keeps the door and the vehicle body in a fixed state, thus closing the door; after the latch retracts from the lock hole in the B-pillar of the vehicle body, the latch and the lock hole are disconnected, allowing the door and the vehicle body to move, that is, the door can rotate around the A-pillar of the vehicle body, thus opening the door.

[0075] One end of the second cable 22 is connected to the handle 21. Specifically, the end of the second cable 22 away from the B-pillar of the vehicle body is pressed onto the handle 21 through a die-casting head to achieve a fixed connection between the second cable 22 and the handle 21. One end of the second cable 22 (i.e., the end connected to the handle 21) is eccentrically positioned relative to the rotation axis of the handle 21, that is, in a direction perpendicular to the rotation axis of the handle 21, one end of the second cable 22 is spaced apart from the rotation axis of the handle 21, so that when the handle 21 rotates around its rotation axis, it can generate a pulling force on the second cable 22.

[0076] The other end of the second cable 22 passes through the second sliding hole 12 and is connected to the latch. The second cable 22 can slide relative to the second sliding hole 12. By turning the handle 21, the second cable 22 can be pulled to slide relative to the second sliding hole 12, thereby pulling the latch out of the lock hole so as to open the car door.

[0077] The second cable 22 includes a second cable wire 221 and a second cable head 222. One end of the second cable wire 221 is fixedly connected to the handle 21 through a die-casting head, and the other end of the second cable wire 221 passes through the second sliding hole 12 and is connected to the second cable head 222. The second cable head 222 is connected to the locking tongue, and the second cable wire 221 can slide relative to the second sliding hole 12.

[0078] Figure 3 This is a third schematic diagram of a door lock assembly according to an exemplary embodiment. After the car door is opened, in order to facilitate the reset of the handle 21 and the latch, so as to facilitate closing and opening the car door again, as shown in the diagram. Figure 3 As shown, a third torsion spring 23 can be sleeved on the fixed shaft 11, with one torsion arm of the third torsion spring 23 connected to the base 1 and the other torsion arm connected to the handle 21. During the process of rotating the handle 21 to pull the bolt out of the lock hole, the handle 21 will squeeze the torsion arm of the third torsion spring 23, thereby generating elastic force in the third torsion spring 23. After the bolt is pulled out of the lock hole, the handle 21 is released, and under the elastic force of the third torsion spring 23, the handle 21 will return to its original position, thereby pushing the bolt to return to its original position.

[0079] Figure 4 This is illustrated according to an exemplary embodiment. Figure 3 In the enlarged schematic diagram of the structure at point A, when the third torsion spring 23 pushes the handle 21 to reset, the handle 21 will collide with the base 1, thus producing an impact sound. To reduce this impact sound, as follows... Figure 4 As shown, a first buffer pad 13 can be provided on the base 1, and a first buffer part 211 is formed on the side of the handle 21 near the cable. The first buffer pad 13 is located on the side of the first buffer part 211 near the base 1. When the handle 21 is rotated to make the latch exit the lock hole, the first buffer part 211 moves away from the first buffer pad 13 as the handle 21 rotates. When the handle 21 is reset, the first buffer part 211 moves close to the first buffer pad 13 and collides with the first buffer pad 13. Under the buffering effect of the first buffer pad 13, the handle 21 can be prevented from directly colliding with the base 1, thereby reducing the impact sound when the handle 21 is reset.

[0080] The first buffer pad 13 can be an elastic component such as rubber, latex, or airbag.

[0081] If the door lock is closed only by using the latch, it is easy to accidentally open the door while the vehicle is in motion, which could lead to danger. Furthermore, after parking and leaving the vehicle, the door can be opened from the outside, making the vehicle vulnerable to theft, thus compromising vehicle safety.

[0082] Based on this, the door lock assembly also includes a safety pin (not shown in the figure), which is located on one side of the base 1 along the length of the vehicle. Specifically, taking the front door rotating around the A-pillar of the vehicle body as an example, when the door is closed, the safety pin is located on the side of the base 1 closer to the B-pillar of the vehicle body; taking the door lock assembly located on the trunk door as an example, when the trunk door rotates around an axis extending along the height of the vehicle body, the safety pin can be located on one side of the base 1 along the width of the vehicle body, and when the trunk rotates around an axis extending along the width of the vehicle body, the safety pin can be located on one side of the base 1 along the height of the vehicle body.

[0083] The safety pin is used to lock the door lock assembly, thereby locking the door to prevent it from being opened while the vehicle is in motion or from being opened from the outside after the vehicle has stopped, thus improving vehicle security.

[0084] Specifically, taking the front door rotating around the A-pillar of the vehicle body as an example, after the door is closed by the latch, the safety pin can be inserted into the safety pin hole in the B-pillar of the vehicle body. The safety pin engages in the safety pin hole, thus locking the door. When the handle 21 is turned accidentally, although the latch can be disengaged from the latch hole, the safety pin remains engaged in the safety pin hole, thus preventing the door from being opened. In addition, when opening the door from the outside of the vehicle, only the latch can be disengaged from the latch hole, and the safety pin remains engaged in the safety pin hole, thus preventing the door from being opened.

[0085] To unlock the car doors, such as Figure 1 As shown, the door lock assembly also includes a stop button 3 and a first pull cable 4. The stop button 3 is rotatably connected to the base 1, and the rotation axis of the stop button 3 is aligned with the height direction of the vehicle. Specifically, the stop button 3 can be rotatably connected to the fixed shaft 11, or a bearing can be provided on the base 1, and a rotating shaft can be provided on the stop button 3. The rotation of the stop button 3 can be achieved by connecting the rotating shaft to the bearing.

[0086] In the following description, we will take the example of the stop button 3 being rotatably connected to the fixed shaft 11.

[0087] like Figure 2 As shown, a first sliding hole 14 extending along the length of the vehicle body is also formed on the base 1. Specifically, a first locking rod 15 is also formed on the side of the base 1 near the B-pillar of the vehicle body, and the first sliding hole 14 is formed on the first locking rod 15.

[0088] One end of the first cable 4 is connected to the stop button 3. One end of the first cable 4 (i.e. the end connected to the stop button 3) is eccentrically set relative to the rotation axis of the stop button 3. By rotating the stop button 3, a pulling force can be generated on the first cable 4.

[0089] The other end of the first cable 4 passes through the first sliding hole 14 and is connected to the safety pin. The first cable 4 can slide relative to the first sliding hole 14. By rotating the stop button 3, the first cable 4 can be pulled to slide relative to the first sliding hole 14, thereby causing the first cable 4 to pull the safety pin out of the safety pin hole, so as to release the safety pin from the door.

[0090] The first cable 4 includes a first cable wire 41 and a first cable head 42. One end of the first cable wire 41 is fixedly connected to the stop button 3, and the other end of the first cable wire 41 passes through the first sliding hole 14 and is connected to the first cable head 42. The first cable head 42 is connected to the safety pin, and the first cable wire 41 can slide relative to the first sliding hole 14.

[0091] In addition, the locking of the door by inserting the safety pin into the safety pin hole and the locking of the door by removing the safety pin from the safety pin hole can be achieved by manually turning the stop button 3 by the people inside the vehicle, or by controlling the rotation of the stop button 3 by the body controller.

[0092] Figure 5 This is a partial cross-sectional view of a door lock assembly according to an exemplary embodiment. When the anti-rotating knob 3 is rotated, the anti-rotating knob 3 will collide with the base 1, producing an impact sound. To reduce this impact sound, as follows... Figure 5 As shown, a second buffer pad 16 is also provided on the fixed base. The second buffer pad 16 is located on the side of the stop button 3 near the base 1. When the stop button 3 is rotated, the stop button 3 will hit the second buffer pad 16, thereby preventing the stop button 3 from directly hitting the base 1 and reducing the impact sound generated when the stop button 3 rotates.

[0093] The second buffer pad 16 can be made of rubber, silicone, airbag, etc.

[0094] Based on this, Figure 6 This is a fourth schematic diagram of a door lock assembly according to an exemplary embodiment. The purpose is to enable the doors to automatically engage and lock without requiring power during a collision, thus preventing a power outage that could hinder rescue of occupants. Figure 6 As shown, the door lock assembly also includes an emergency unlocking device 5. The emergency unlocking device 5 is fixed to the base 1 and connected to the first cable 4, and is used to pull the safety pin out of the safety pin hole in the event of a vehicle collision to unlock the door.

[0095] Figure 7 This is the fifth schematic diagram of a door lock assembly according to an exemplary embodiment, as shown below. Figure 7 As shown, the emergency unlocking device 5 includes a fixing seat 51, which is snapped onto the base 1.

[0096] Specifically, Figure 8 This is illustrated according to an exemplary embodiment. Figure 1 An enlarged schematic diagram of the structure at point B is shown below. Figure 8 As shown, a first fixing plate 17 is provided on the base 1, and a first snap-fit ​​hole 171 is provided on the first fixing plate 17. A first snap-fit ​​plate 511 is provided on the fixing seat 51, and the first snap-fit ​​plate 511 is snapped into the first snap-fit ​​hole 171. Figure 9 This is illustrated according to an exemplary embodiment. Figure 7 An enlarged schematic diagram of the structure at point C is shown below. Figure 9 As shown, a second fixing plate 18 is also provided on the base 1. The second fixing plate 18 is arranged opposite to the first fixing plate 17. A second snap-fit ​​hole 181 is provided on the second fixing plate 18. A second snap-fit ​​plate 512 is provided on the fixing seat 51. The second snap-fit ​​plate 512 is arranged opposite to the first snap-fit ​​plate 511. The second snap-fit ​​plate 512 is snapped into the second snap-fit ​​hole 181.

[0097] Both the first locking plate 511 and the second locking plate 512 are elastic. The first locking plate 511 engages with the first locking hole 171, and the second locking plate 512 engages with the second locking hole 181, thus securing the fixing base 51 to the base 1. This facilitates the disassembly and installation of the fixing base 51 and the base 1. Alternatively, the fixing base 51 and the base 1 can also be engaged using other methods, such as locking with a slot or a clip, or a snap-fit ​​connection.

[0098] like Figure 6 As shown, the emergency unlocking and stopping device 5 also includes a first elastic element 52, a rotating element 53 and an inertial element 54. The first elastic element 52 is connected to the fixed base 51 and is connected to the rotating element 53. The rotating element 53 is rotatably connected to the fixed base 51. The rotating element 53 has a pulling part 531 that is eccentrically arranged relative to the first axis. The pulling part 531 is used to connect the safety pin of the door lock assembly.

[0099] For example, Figure 10 This is a cross-sectional structural schematic diagram of a door lock assembly according to an exemplary embodiment, such as... Figure 10 As shown, the first axis can coincide with the axis of the fixed shaft 11, that is, the fixed shaft 11 can pass through the base 1 and be connected to the fixed seat 51. The rotating part 53 is rotatably connected to the fixed shaft 11. At this time, the pulling part 531 can be connected to the end of the first cable 4 away from the safety pin. Thus, the first cable 4 can be moved by the rotation of the rotating part 53, thereby pulling the safety pin out of the safety pin hole to unlock the car door.

[0100] For example, the first axis can also be parallel to the axis of the fixed axis 11, that is, the rotating member 53 and the stop button 3 rotate around two different axes respectively. In this case, the stop button 3 is connected to the safety pin through the first cable 4, and the rotating member 53 is connected to the safety pin through another cable. In this case, the rotation of the rotating member 53 can pull the safety pin out of the safety pin hole, and can avoid the rotation of the stop button 3 and the rotation of the rotating member 53 from affecting each other.

[0101] The inertial member 54 is connected to the fixed base 51 and can move from the third position to the fourth position under the action of inertia. The rotating member 53 can rotate around the first axis between the first position and the second position. When the rotating member 53 is in the first position, it presses the first elastic member 52, so that the first elastic member 52 is in a compressed state. At this time, the safety pin locks the vehicle door, that is, the safety pin is inserted into the safety pin hole and the door is in a locked state. At this time, the inertial member 54 is in the third position and the inertial member 54 also abuts against the rotating member 53. Thus, the rotating member 53 is limited to the first position by the abutment between the inertial member 54 and the rotating member 53, so as to prevent the rotating member 53 from rotating under the elastic force of the first elastic member 52, thereby ensuring that the safety pin locks the door.

[0102] Figure 11 This is one of the schematic diagrams illustrating the positional relationship between the rotating member 53 and the inertial member 54 when the rotating member 53 is in a first position and the inertial member 54 is in a third position, according to an exemplary embodiment. Figure 11 As shown, when the vehicle is in normal driving condition, the safety pin locks the door. At this time, the rotating part 53 is in the first position and the inertial part 54 is in the third position.

[0103] Figure 12 This is a schematic diagram illustrating the positional relationship between the rotating member 53 and the inertial member 54 when the rotating member 53 is in the second position and the inertial member 54 is in the fourth position, according to an exemplary embodiment. Figure 12 As shown, when a vehicle is involved in a collision, the vehicle stops rapidly from its driving state due to the collision. At this time, the inertial component 54 will move from the third position to the fourth position under the action of inertia, thereby releasing the inertial lock from the rotating component 53. This allows the rotating component 53 to move from the first position to the second position under the action of the first elastic component 52.

[0104] After the rotating member 53 rotates to the second position, that is, when the rotating member 53 is in the second position, the elastic force of the first elastic member 52 is released, so that the first elastic member 52 is in a natural state, and the rotation of the rotating member 53 will cause the pulling part 531 to pull the safety pin, so that the safety pin releases the door from the lock.

[0105] It should be noted that the inertial component 54 has a relatively large mass. When the inertia generated during a vehicle collision reaches a certain preset value, the inertial component 54 will move significantly under the action of inertia, thereby moving the inertial component 54 from the third position to the fourth position, so that the inertial component 54 releases its contact with the rotating component 53.

[0106] With the cooperation of the inertial component 54 and the rotating component 53, when a vehicle collision occurs, the inertia of the inertial component 54 can release the restriction on the rotating component 53, and the rotation within the rotating component 53 can drive the safety pin to release the lock on the door. Thus, in the event that the vehicle loses power and the occupants lose their ability to move freely, the door can be opened from the outside to facilitate the rescue of the occupants, thereby reducing rescue time and improving rescue efficiency.

[0107] Furthermore, rescuing occupants from the vehicle does not require damaging the door lock assembly, and vehicle repairs do not require repairing the door lock assembly, thereby reducing vehicle maintenance costs.

[0108] The first elastic element 52 can be rubber, an air bladder, a tension spring, a compression spring, a torsion spring, etc. Here, we will take an example where the first axis coincides with the axis of the fixed shaft 11, and the first elastic element 52 is a first torsion spring 521. Figure 10 As shown, the axis of the first torsion spring 521 coincides with the first axis, and one torsion arm of the first torsion spring 521 is connected to the fixed base 51, while the other torsion arm of the first torsion spring 521 is connected to the rotating member 53.

[0109] Specifically, such as Figure 10 As shown, the rotating component 53 includes a rotating shaft 532 and a limiting block 533. The rotating shaft 532 is rotatably connected to the fixed seat 51, that is, a mounting shaft 513 is formed on the fixed seat 51. A mounting hole 5131 is formed in the mounting shaft 513, which passes through the fixed seat 51 along the height direction of the vehicle body. At least a part of the rotating shaft 532 is located in the mounting hole 5131 and can rotate in the mounting hole 5131, so as to realize the rotatable connection between the rotating shaft 532 and the fixed seat 51. The rotating shaft 532 can rotate around its axis, and the axial direction of the rotating shaft 532 is consistent with the height direction of the vehicle.

[0110] The limiting block 533 is fixed on the rotating shaft 532. A pulling part 531 is formed on the limiting block 533. The rotation of the rotating shaft 532 can drive the limiting block 533 to rotate, thereby driving the pulling part 531 to rotate as well, so that the pulling part 531 pulls the safety pin out of the safety pin hole, thereby unlocking the car door.

[0111] Figure 13 This is one of the partial structural schematic diagrams of a door lock assembly according to an exemplary embodiment, such as... Figure 13As shown, the first torsion spring 521 is sleeved on the mounting shaft 513, and one torsion arm of the first torsion spring 521 (such as...) Figure 13 The torque arm A1 shown is snapped onto the fixed base 51, and the other torque arm of the first torsion spring 521 (as shown) is... Figure 13 The torque arm A2 shown is engaged with the limiting block 533. When the rotating member 53 is in the first position, it will compress the torque arm of the first torsion spring 521, thereby causing the first torsion spring 521 to generate elastic force.

[0112] Furthermore, in order to facilitate assembly and to facilitate the control of the safety pin by the stop button 3 and the rotating part 53 respectively, the axis of the rotating shaft 532 is usually made to coincide with the first axis. That is, a rotating hole 5321 extending along the height direction of the vehicle body is formed in the rotating shaft 532. The fixed shaft 11 passes through the rotating hole 5321 and is connected to the fixed seat 51. The rotating shaft 532 is rotatably connected to the fixed shaft 11, so that the axis of the rotating shaft 532 coincides with the first axis by both the rotating shaft 532 and the stop button 3 being rotatably connected to the fixed shaft 11.

[0113] Based on this, when the first elastic element 52 drives the rotating element 53 to rotate from the first position to the second position, the first elastic element 52 will collide with the fixed seat 51 and produce a loud collision sound. In order to reduce this collision sound, such as Figure 1 As shown, a third buffer pad 55 is provided on the fixed base 51, and a buffer boss 5331 is provided on the limiting block 533 of the rotating member 53. Along the direction of rotation of the rotating member 53 from the first position to the second position, the buffer boss 5331 and the third buffer pad 55 are arranged in sequence. When the rotating member 53 rotates to the second position, the buffer boss 5331 and the third buffer pad 55 collide, thereby avoiding the collision between the rotating member 53 and the fixed base 51, thus reducing the impact noise during the rotation of the rotating member 53.

[0114] The third buffer can be made of rubber, latex, airbag, etc.

[0115] In some embodiments, when the rotation axis of the stop button 3 coincides with the first axis, that is, when both the stop button 3 and the rotating member 53 are rotatably connected to the fixed shaft 11, and both the rotating member 53 and the stop button 3 control the safety pin to unlock the door through the first cable 4, the movement of the first cable 4 driven by the stop button 3 will cause the rotating member 53 to rotate, which will affect the structural stability of the emergency unlocking device 5.

[0116] Based on this Figure 14 This is illustrated according to an exemplary embodiment. Figure 2 An enlarged schematic diagram of the structure at point D is shown below. Figure 14As shown, the rotating member 53 has a clearance portion 534 extending circumferentially around the first axis. Specifically, the clearance portion 534 is provided on the limiting block 533. The clearance portion can be a clearance groove, a clearance hole, a clearance guide rail, etc. Here, a clearance hole is used as an example for explanation.

[0117] The clearance portion 534 has a starting end 5341 and an ending end 5342, and rotates along the direction of rotation of the rotating member 53 from the first position to the second position (e.g., Figure 14 The direction shown is X), with the starting end 5341 and the ending end 5342 arranged in sequence. The door lock assembly also includes a first connecting rod 6, one end of which is connected to the stop button 3, and the other end of which is slidably connected to the clearance part 534. One end of the first pull cable 4 (i.e., the end away from the safety pin) is connected to the first connecting rod 6.

[0118] Rotating the stop button 3 can cause the first connecting rod 6 to slide between the starting end 5341 and the ending end 5342, thereby causing the first connecting rod 6 to slide the first cable 4, which in turn causes the first cable 4 to move the safety pin, so that the safety pin can lock and unlock the door.

[0119] Specifically, when the safety pin is released from the door by the stop button 3, the rotation direction of the stop button 3 is the same as the rotation direction of the rotating member 53 when the safety pin is released from the door by the rotating member 53, that is, both are the same as the direction in which the rotating member 53 rotates from the first position to the second position.

[0120] When the safety pin locks the door, the first connecting rod 6 is located at the starting end 5341 of the clearance part 534; during the process of rotating the stop button 3 to control the safety pin to unlock the door, the stop button 3 can drive the first connecting rod 6 to slide relative to the clearance part 534 from the starting end 5341 to the ending end 5342; during the process of the stop button 3 resetting, the stop button 3 can drive the first connecting rod 6 to slide relative to the clearance part 534 from the starting end 5341 to the ending end 5342.

[0121] By sliding the first connecting rod 6 with the avoidance part 534, the rotating part 53 will not rotate during the rotation of the safety pin, thereby avoiding the influence on the rotating part 53, thus ensuring the position and connection of the rotating part 53 and the inertial part 54, ensuring the structural stability of the emergency unlocking and stopping device 5, and thus ensuring that the emergency unlocking and stopping device 5 can work normally when a vehicle collision occurs.

[0122] The pulling part 531 is located at the starting end 5341 of the clearance part 534. Specifically, taking the clearance part 534 as a clearance hole as an example, the pulling part 531 can be the inner wall of the clearance slot at the starting end 5341, or it can be a push block provided at the starting end 5341. During the rotation of the rotating member 53 from the first position to the second position, the first connecting rod 6 is located at the starting end 5341 and abuts against the pulling part 531.

[0123] Specifically, when the safety pin locks the door, the first connecting rod 6 is located at the starting end 5341 of the avoidance part 534 and abuts against the pulling part 531. When the rotating member 53 rotates from the first position to the second position, it will drive the avoidance part 534 to rotate in the direction of the rotating member 53 rotating from the first position to the second position. This will drive the starting end 5341 and the pulling part 531 to rotate in the direction of the rotating member 53 rotating from the first position to the second position. This will enable the pulling part 531 to push the first connecting rod 6 to move, and then the first connecting rod 6 will pull the first cable 4 to move, so that the first cable 4 will pull the safety pin to release the door from the lock.

[0124] In some embodiments, the inertial member 54 can rotate from the third position to the fourth position or translate from the third position to the fourth position under the action of inertia.

[0125] For example, the inertial component 54 can be translated from the third position to the fourth position under the action of inertia. Figure 15 This is a second schematic diagram illustrating the positional relationship between the rotating member and the inertial member when the rotating member is in a first position and the inertial member is in a third position, according to an exemplary embodiment. Figure 15 As shown, the inertial component 54 can be a sliding block with a large mass. The fixed base 51 is provided with a sliding rod 514 extending along an axis perpendicular to the fixed shaft 11. The inertial component 54 is slidably connected to the sliding rod 514. When the rotating component 53 is in the first position and the inertial component 54 is in the third position, the end of the inertial component 54 near the sliding component abuts against the limiting block 533, thereby restricting the rotating component 53 to the first position.

[0126] When a vehicle collision occurs, the inertial member 54 will slide from the third position to the fourth position along the slide bar 514 under the action of inertia, thereby freeing the inertial member 54 from restricting the rotating member 53, so that the rotating member 53 can rotate from the first position to the second position under the action of the first elastic member 52, so that the safety pin can be released from locking the door.

[0127] For example, the inertial component 54 can rotate from the third position to the fourth position under the action of inertia. Figure 16 This is a second schematic diagram of a partial structure of a door lock assembly according to an exemplary embodiment, such as... Figure 16As shown, the inertial component 54 includes an inertial lock 541 and a blocking boss 542. The inertial lock 541 is rotatably connected to the fixed base 51 and can rotate from the third position to the fourth position around the second axis under the action of inertia, so that the inertial component 54 can move from the third position to the fourth position.

[0128] Specifically, an inertia shaft 515 is rotatably connected to the fixed base 51. The inertia shaft 515 can rotate around its axis, and the axis of the inertia shaft 515 is aligned with the height direction of the vehicle body. An inertia lock 541 is fixed to the inertia shaft 515 and can rotate synchronously with the inertia shaft 515. The axis of the inertia shaft 515 is the second axis.

[0129] The inertia lock 541 has a relatively large mass. When the inertia generated during a vehicle collision reaches a certain preset value, the inertia lock 541 will rotate significantly under the action of inertia, and drive the inertia shaft 515 to rotate, thereby enabling the inertia component 54 to rotate from the third position to the fourth position.

[0130] The blocking boss 542 is fixed on the inertia lock 541 and is located on the side of the second axis close to the rotating member 53. When the inertia lock 541 is in the third position, the blocking boss 542 abuts against the rotating member 53 so that the inertia member 54 abuts against the rotating member 53. When the inertia lock 541 is in the fourth position, the blocking boss 542 releases its abutment against the rotating member 53 so that the inertia member 54 releases its abutment against the rotating member 53.

[0131] Specifically, such as Figure 11 As shown, when the inertia lock 541 is in the third position, it rotates along the direction of the rotating member 53 from the first position to the second position (e.g., Figure 11 In the direction X shown, the limiting block 533 and the blocking boss 542 are arranged in sequence and abut against each other. By blocking the limiting block 533 through the blocking boss 542, the inertial member 54 blocks the rotating member 53, thereby limiting the rotating member 53 to the first position when the inertial member 54 is in the third position.

[0132] When a vehicle collision occurs, the inertia lock 541 rotates from the third position to the fourth position under the action of inertia, such as... Figure 12 As shown, when the inertia lock 541 is in the fourth position, the blocking boss 542 is located on the side of the limiting block 533 close to the inertia member 54, so that the blocking boss 542 and the limiting block 533 no longer abut, thereby releasing the restriction on the rotating member 53. The rotating member 53 can rotate from the first position to the second position under the action of the first elastic member 52, so that the safety pin can be released from locking the door.

[0133] The rotation direction of the inertial lock 541 can be the direction in which the inertial lock 541 blocks the boss 542 from moving away from the limit block 533 when the inertial lock 541 is in the third position (e.g., Figure 12The direction Y shown in the figure can also be used to block the boss 542 from moving away from the limit block 533 when the inertial lock 541 is in the third position (e.g., Figure 12 (The direction Z is shown in the figure). Here, we will take the rotation direction of the inertial lock 541 as the direction in which the inertial lock 541 blocks the boss 542 away from the limit block 533 when the inertial lock 541 is in the third position as an example.

[0134] Specifically, such as Figure 11 As shown, the blocking boss 542 has a first guide arc surface 5421 and a clearance notch 5422 on the side near the rotating member 53. Along the direction of rotation of the inertial lock 541 from the third position to the fourth position, the clearance notch 5422 and the first guide arc surface 5421 are arranged in sequence.

[0135] During the rotation of the inertial lock 541 from the third position to the fourth position, the blocking boss 542 pushes the limiting block 533 in the direction from the second position to the first position, and allows the first guide arc surface 5421 to slide relative to the limiting block 533; that is, the inertial lock 541 along... Figure 12 The direction Z shown in the figure is rotated. During this rotation, the blocking boss 542 abuts against the limiting block 533. The blocking boss 542 will squeeze and push the limiting block 533, and then the limiting block 533 will contact the first guide arc surface 5421, and the limiting block 533 will slide relative to the first guide arc surface 5421 until the inertial lock 541 rotates to the fourth position.

[0136] When the inertial lock 541 rotates to the fourth position, if Figure 12 As shown, the limiting block 533 no longer contacts the first guide arc surface 5421, and at least a portion of the limiting block 533 is located within the clearance notch 5422, thereby preventing the blocking boss 542 from blocking the limiting block 533. That is, the inertial member 54 no longer restricts the rotating member 53. The rotating member 53 will rotate from the first position to the second position under the action of the first elastic member 52, and in this process, it will drive the first cable 4 to move, so that the first cable 4 will drive the safety pin moving rod to unlock the door.

[0137] By making the rotation direction of the inertial lock 541 opposite to that of the rotating component 53, the inertial lock 541 can better abut against the rotating component 53, thereby increasing the stability of the connection between the two and enhancing the structural stability of the emergency unlocking and stopping device 5.

[0138] In some embodiments, to enhance the stability of the inertial element 54 in the third position, such as Figure 1 and Figure 16 As shown, a limiting boss 543 is formed on the inertial member 54. Specifically, the limiting boss 543 is formed on the inertial lock 541. A limiting member 516 is provided on the fixed base 51, which is positioned along the direction of rotation of the inertial member 54 from the third position to the fourth position (e.g., Figure 16In the direction M shown, the limiting member 516 and the limiting boss 543 are arranged in sequence, and when the inertial member 54 is in the third position, the limiting member 516 and the limiting boss 543 abut against each other to limit the inertial member 54 to be in the third position.

[0139] The limiting member 516 can be a protruding rib formed on the fixed base 51 or a stop block set on the fixed base 51. When the inertial member 54 is in the third position and the rotating member 53 is in the first position, the limiting member 516 blocks the inertial member 54, which can prevent the rotating member 53 from squeezing the inertial member 54 under the action of the first elastic member 52, thus causing the inertial member 54 to rotate, thereby further enhancing the structural stability of the inertial member 54 and the rotating member 53.

[0140] In some embodiments, since the derailleur 3 and the rotating member 53 are connected by the first connecting rod 6, and during a vehicle collision, as the rotating member 53 rotates from the first position to the second position, the pulling part 531 drives the first connecting rod 6 to rotate synchronously, thereby causing the first connecting rod 6 to drive the derailleur 3 to rotate. After the collision ends, the derailleur 3 can be reset by manually rotating it or by controlling the derailleur 3 to reset via the body control unit, thereby causing the derailleur 3 to drive the first connecting rod 6 to move, which in turn drives the rotating member 53 to reset, even if the rotating member 53 rotates to the first position.

[0141] After the rotating component 53 returns to the first position, in order to quickly reset the inertial component 54, such as... Figure 10 As shown, the inertial member 54 also includes a second elastic member 544, which is connected to the fixed base 51 and to the inertial member 54. When the inertial member 54 is in the third position, the second elastic member 544 is in a natural state. When the inertial member 54 is in the fourth position, the second elastic member 544 is compressed. That is, after a vehicle collision, the inertial member 54 moves from the third position to the fourth position under the action of inertia, thereby squeezing the second elastic member 544 and compressing it to make the second elastic member 544 elastic.

[0142] After the collision ends, the second elastic element 544 will push the inertial element 54 from the fourth position to the third position to reset the inertial element 54, thereby resetting the emergency unlocking device 5 for reuse.

[0143] The second elastic element 544 can be rubber, air bladder, tension spring, compression spring, torsion spring, etc. Here, we will take the second torsion spring 5441 as an example to illustrate the second elastic element 544.

[0144] Specifically, such as Figure 16 As shown, the axis of the second torsion spring 5441 coincides with the second axis, and one torsion arm of the second torsion spring 5441 is connected to the fixed base 51, while the other torsion arm of the second torsion spring 5441 is connected to the inertial member 54.

[0145] That is, the second torsion spring 5441 can be sleeved on the inertia shaft 515, and one torsion arm of the second torsion spring 5441 (such as...) Figure 16 The torque arm B1 shown is snapped onto the fixed base 51, and the other torque arm of the second torsion spring 5441 (such as...) Figure 16 The torque arm B2 shown is engaged with the inertial member 54. During the rotation of the inertial member 54 from the third position to the fourth position, it will compress the torque arm of the second torsion spring 5441, thereby generating elastic force in the second torsion spring 5441. This facilitates the inertial member 54 to reset under the action of the elastic force of the second torsion spring 5441 after the vehicle collision ends.
