Description

Technical Field

[0001] The present application relates to the technical field of vehicle collision unlocking, and in particular to a collision unlocking control device and a vehicle. Background Art

[0002] To ensure that occupants can open their doors and escape danger in the event of a collision, vehicles are typically equipped with a collision unlock feature. This feature automatically unlocks the vehicle via a drive motor in the event of a collision, preventing occupants from being trapped. However, this traditional collision unlock mechanism relies on complex mechanical structures and motor drives, which presents certain drawbacks.

[0003] First, the unlocking time of mechanical transmission is relatively long, usually requiring about 500 milliseconds of motor drive time to complete the unlocking action. In the event of a vehicle collision, if the power supply system in the vehicle is quickly powered off due to a violent impact, this time delay may prevent the unlocking drive from being completed. Secondly, collision accidents are often accompanied by strong impact forces, which may cause deformation or damage to the door or the lock body inside the door lock. In this case, even if the power supply is normal, the door lock may not be unlocked normally due to the mechanical structure of the lock being stuck. The above two defects will undoubtedly hinder the rapid escape of people in the car, delay rescue time, and even lead to tragedy. Utility Model Content

[0028] The embodiments of the present application respectively provide a collision unlocking control device and a vehicle, which will be described in detail below.

[0029] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the hardware structure of a first optional embodiment of a collision unlocking control device shown in an exemplary embodiment of the present application. Figure 1 As shown, the collision unlocking control device includes a collision detection module 110 for performing vehicle collision detection, a detonator 120 for blasting the locking mechanism in the lock body, and a detonation control module 130 for generating a blasting signal; the detonator 120 is arranged at the lock body of the vehicle door lock and cooperates with the locking mechanism. The locking mechanism is destroyed by detonating the detonator 120 to unlock the vehicle door; the collision detection module 110 is connected to the detonation control module 130, and the detonation control module 130 is connected to the detonator 120.

[0030] As can be seen, this embodiment can perform real-time collision detection through the collision detection module 110. When a collision is detected, the collision detection module 110 transmits a collision signal to the detonation control module 130, triggering the detonation control module 130 to generate a blasting signal, which detonates the detonator 120 to destroy the locking mechanism of the lock body to unlock the vehicle door. No motor drive is required, and the unlocking speed is extremely fast, approximately 30ms, an order of magnitude faster than the unlocking speed of the drive motor. Even if the power system is quickly cut off due to a vehicle collision, the vehicle door can still be unlocked in time, effectively avoiding the risk of being unable to unlock due to power interruption. Even if the vehicle door or lock body is deformed or damaged due to a vehicle collision, the detonator can still complete the door unlocking by destroying the locking mechanism of the lock body. This fast and reliable unlocking mechanism ensures that occupants can quickly escape the vehicle in the event of a collision, reducing the risk of entrapment and injury, thereby improving occupant safety.

[0031] According to the above description, in an exemplary embodiment, the collision detection module 110 can be a collision sensor, or it can be other equipment, devices or instruments that can perform collision detection and directly generate or generate a collision signal based on the detection results. As an example, in this embodiment or some other embodiments, the collision detection module 110 can be one or more collision sensors such as collision sensing sensors, acceleration sensors, pressure sensors, etc. There can be multiple collision sensors at different positions of the vehicle, which can be respectively set at the left front, right front, left middle, right middle, left rear and right rear of the car body. Of course, the collision detection module 110 can also be set as a collision sensor in the ABM (Air Bag Module, airbag module or airbag controller).

[0032] In an exemplary embodiment, the initiator 120 may include a gas generator that generates explosive gas, or other equipment, devices, or instruments capable of generating explosive combustion gas. For example, in this or other embodiments, the initiator 120 includes explosive fuel and a piston device. The high-pressure gas generated by the explosive combustion drives the piston device integrated therein to rapidly move toward the locking mechanism of the lock body and strike the locking mechanism, thereby destroying the locking mechanism.

[0033] In an exemplary embodiment, the vehicle door lock may be at least one of the left front door lock, the right front door lock, the left rear door lock, and the right rear door lock. As an example, in this embodiment or some other embodiments, the detonator 120 may be provided on the lock body of only the front door lock (including the left front door lock and the right front door lock) to cooperate with the locking mechanism.

[0034] In one exemplary embodiment, the initiator 120 cooperates with the locking mechanism, including being positioned around the locking mechanism or being positioned on the locking mechanism. In response to a blasting signal, the initiator 120 triggers an explosion to destroy the locking mechanism, thereby unlocking the vehicle door. The locking mechanism within the lock body is a key component for locking or unlocking the vehicle door, and therefore presents a major obstacle to escape for occupants in the event of a collision. By positioning the initiator 120 within the lock body and cooperating with the locking mechanism, detonating the initiator 120 destroys the locking mechanism, effectively opening the vehicle door.

[0035] The locking mechanism includes a catch, ratchet, and pawl. Within the door lock body, these three elements work together to lock and unlock the door. When the door is closed, the catch engages with the door's latch, and the pawl engages the catch, locking it and locking the door. To open the door, the pawl releases the catch, releasing the locking mechanism and unlocking the door. Therefore, the detonator 120 is located within the locking mechanism, specifically on any of the catch, ratchet, and pawl.

[0036] In one exemplary embodiment, the detonator 120 can be located at the latch plate in the locking mechanism. Detonating the detonator 120 destroys the latch plate, unlocking the door. Alternatively, the detonator 120 can be located at the ratchet wheel in the locking mechanism. Detonating the detonator 120 explosively destroys the ratchet wheel, unlocking the door. Alternatively, the detonator 120 can be located at the pawl wheel in the locking mechanism. Detonating the detonator 120 explosively destroys the pawl, unlocking the door. Since ratchets are typically made of plastic, destroying them is easier. Therefore, placing the detonator 120 at the ratchet wheel can improve the success rate of door unlocking. For example, in this or other embodiments, the detonator 120 can be mounted perpendicular to the ratchet wheel. In response to an explosion signal, the detonator 120 generates high-pressure gas through explosive combustion, driving a piston assembly to rapidly move toward the ratchet wheel and impact it, breaking it and thereby unlocking the door.

[0037] In an exemplary embodiment, the collision detection module 110 and the detonation control module 130 are connected via a hard wire to improve reliability, and the detonation control module 130 and the initiator 120 may be connected via a hard wire.

[0038] In an exemplary embodiment, the detonation control module 130 can be an ACU (Auto Controlled Unit), an ABM, or another ECU (Electronic Controller Unit) that rapidly responds to and generates a detonation signal upon receiving a collision signal. For example, upon receiving the collision signal, the ABM transmits the detonation signal to the detonator 120 via a hardwire. The detonator 120 then explodes and burns internally, generating high-pressure gas. This drives the piston assembly to rapidly move toward the ratchet, striking it and breaking it. This allows the spring to automatically reset the latch plate, allowing the door to open automatically.

[0039] In another exemplary embodiment, the collision detection module 110 may be an ABM or an ACU, and the detonation control module 130 may be a vehicle controller.

[0040] In an exemplary embodiment, Figure 2 As shown, the collision unlocking control device further includes an unlocking control module 140 for controlling the unlocking of the vehicle door lock; the unlocking control module 140 is connected to the detonation control module 130. As an example, the unlocking control module 140 and the detonation control module 130 are connected via a CAN line. After the detonation control module 130 receives the collision signal detected by the collision detection module 110, it transmits the signal to the unlocking control module 140, so that the unlocking control module 140 controls the unlocking of the vehicle door lock. Alternatively, the detonation control module 130 generates an unlocking request based on the collision signal detected by the collision detection module 110 and transmits the request to the unlocking control module 140, so that the unlocking control module 140 controls the unlocking of the vehicle door.

[0041] In another exemplary embodiment, Figure 3 As shown, the collision unlocking control device further includes an unlocking control module 140 for controlling the unlocking of the vehicle door lock; the unlocking control module 140 is connected to the collision detection module 110. As an example, the unlocking control module 140 and the collision detection module 110 can be connected wirelessly or by wire. When the collision detection module 110 sends the detected collision signal to the detonation control module 130, it can also send the collision signal to the unlocking control module 140, so that the unlocking control module 140 controls the unlocking of the vehicle door.

[0042] Figure 2 and Figure 3The illustrated embodiments all enable simultaneous detonation and actuation unlocking on a single vehicle. For example, a detonator 120 can be installed on the lock body of the left front door lock. Working in conjunction with the locking mechanism, the detonation control module 130, upon receiving a collision signal from the collision detection module 110, generates a detonation signal to detonate the detonator 120 installed on the lock body of the left front door lock. Furthermore, the unlocking control module 140 can receive a collision signal / unlock request from the detonation control module 130, or a collision signal from the collision detection module 110, to control the unlocking of other door locks. This ensures that at least one door can be successfully opened, allowing occupants to escape quickly. Furthermore, since only the locking mechanism of one door lock body is damaged, only one door lock body needs to be repaired or replaced, effectively reducing maintenance costs.

[0043] In an exemplary embodiment, the unlocking control module 140 may be at least one of a CEM (Central Electronic Module), a BCM (Body Control Module), a BDC (Body Domain Controller), or a DCM (Door Control Module), or other device, apparatus, or instrument capable of promptly controlling door unlocking upon receiving a collision signal or an unlock request. By way of example, the unlocking control module 140 may be any one of the CEM, BCM, BDC, or DCM, with the CEM, BCM, BDC, or DCM directly controlling door unlocking. Alternatively, the unlocking control module 140 may include a CEM and DCM, or a BCM and DCM, or a BDC and DCM. The CEM, BCM, or BDC communicates with the DCM to control door unlocking.

[0044] In a specific embodiment of the present application, the collision detection module 110 is a collision sensor, the detonation control module 130 is an ABM, and the unlocking control module 140 includes a BCM and a DCM; the ABM is connected to the collision sensor, the detonator 120 and the BCM respectively, and the BCM is connected to the DCM; the collision sensor transmits the collision signal to the ABM; after receiving the collision signal, the ABM generates a blasting signal to control the detonator 120 to detonate, so as to realize detonation unlocking. At the same time, the ABM transmits the collision signal to the BCM, and after receiving the collision signal, the BCM sends an unlocking request or unlocking signal to the DCM to realize drive unlocking.

[0045] In another specific embodiment of the present application, the collision detection module 110 is a collision sensor, the detonation control module 130 is an ABM, and the unlocking control module 140 includes a BCM and a DCM; the collision sensor is connected to the ABM and the BCM respectively, the ABM is connected to the detonator 120, and the BCM is connected to the DCM; the collision sensor transmits the collision signal to the ABM and the BCM respectively; after receiving the collision signal, the ABM generates a blasting signal to control the detonator 120 to detonate or detonate, so as to realize detonation unlocking; after receiving the collision signal, the BCM sends an unlocking request or an unlocking signal to the DCM to realize drive unlocking.

[0046] In an exemplary embodiment, Figure 4 As shown, the collision unlocking control device further includes a first switch 150 for enabling or disabling the detonation control module 130 from generating a blasting signal. First switch 150 is connected to detonation control module 130. For example, a user can enable or disable first switch 150 based on their needs. First switch 150 controls whether detonation control module 130 generates a blasting signal based on the user's activation or deactivation. When first switch 150 enables detonation control module 130 to generate a blasting signal, detonation control module 130 immediately generates a blasting signal upon receiving a collision signal, causing detonator 120 to detonate. When detonation control module 130 is disabled from generating a blasting signal, detonation control module 130 does not generate a blasting signal upon receiving a collision signal, and detonator 120 does not detonate. This embodiment enables flexible on / off switching of the detonation unlocking function based on user needs, improving the user experience.

[0047] In a specific embodiment of the present application, Figure 5 As shown, the detonation control module 130 is connected to the collision detection module 110, the initiator 120, and the first switch 150, respectively. The unlocking control module 140 is also connected to the collision detection module 110. When the first switch 150 activates the detonation control module 130 to generate a detonation signal, the collision detection module 110 transmits the detected collision signal to the detonation control module 130 and the unlocking control module 140. The detonation control module 130 generates a detonation signal to control the detonator 120 to detonate, and the unlocking control module 140 controls the vehicle door to unlock, thus implementing two collision unlocking modes: point unlocking and driven unlocking. When the first switch 150 deactivates the detonation control module 130 to generate a detonation signal, the collision detection module 110 transmits the detected collision signal to the detonation control module 130 and the unlocking control module 140. In this case, the detonation control module 130 cannot generate a detonation signal, and thus point unlocking is not executed. Only the unlocking control module 140 controls the vehicle door to unlock, thus implementing driven unlocking.

[0048] In another specific embodiment of the present application, Figure 6As shown, the detonation control module 130 is connected to the collision detection module 110, the detonator 120, the unlocking control module 140, and the first switch 150, respectively. As an example, the driven unlocking mode and the explosive unlocking mode are independent of each other. That is, the driven unlocking mode is always enabled. The explosive unlocking mode is enabled when the first switch 150 is enabled and the detonation control module 130 generates an explosive signal, and is disabled when the first switch 150 is disabled and the detonation control module 130 generates an explosive signal. When the first switch 150 is enabled and the detonation control module 130 generates an explosive signal, the collision detection module 110 transmits the detected collision signal to the detonation control module 130. The detonation control module 130 generates an explosive signal to control the detonator 120 to detonate, executing explosive unlocking. Simultaneously, the detonation control module 130 transmits a collision signal or an unlock request to the unlocking control module 140 to unlock the vehicle door, executing driven unlocking. In a scenario where the first switch 150 disables the detonation control module 130 from generating a blasting signal, the collision detection module 110 sends the detected collision signal to the detonation control module 130. The detonation control module 130 does not generate a blasting signal, and thus does not execute detonation unlocking. However, the detonation control module 130 can send a collision signal or an unlocking request to the unlocking control module 140 to control the unlocking of the vehicle door and execute drive unlocking.

[0049] As another example, the drive unlock mode and the detonation unlock mode are interrelated. That is, the detonation unlock mode is enabled or disabled when the first switch 150 is turned on or off, causing the detonation control module 130 to generate a blasting signal. The drive unlock mode is disabled when the detonation unlock mode is enabled, and enabled when the detonation unlock mode is disabled. If the first switch 150 is turned on and the detonation control module 130 generates a blasting signal, the collision detection module 110 transmits the detected collision signal to the detonation control module 130. The detonation control module 130 can generate a blasting signal to control the detonator 120 to detonate, executing the detonation unlock. In this case, the detonation control module 130 does not transmit a collision signal or an unlock request to the unlock control module 140, and thus does not execute the drive unlock. In a scenario where the first switch 150 disables the detonation control module 130 from generating a blasting signal, the collision detection module 110 sends the detected collision signal to the detonation control module 130. The detonation control module 130 does not generate a blasting signal, and thus does not execute detonation unlocking. However, the detonation control module 130 can send a collision signal or an unlocking request to the unlocking control module 140 to control the unlocking of the vehicle door and execute drive unlocking.

[0050] Both of the above examples can realize dynamic selection of unlocking methods and improve user experience.

[0051] In a specific embodiment of the present application, the first switch 150 can be a physical switch button set in the vehicle, or it can be a vehicle-mounted central control screen, or it can be a user mobile device such as a mobile phone, tablet, or laptop computer. For example, if the first switch 150 is a physical switch button, the physical switch button is connected to the detonation control module 130. The user can operate the switch button, and the switch button transmits different level signals (high level or low level) to the detonation control module 130 according to the switch change, thereby indicating whether the detonation control module 130 generates a blasting signal. If the first switch 150 is a vehicle-mounted central control screen / user mobile device, a soft switch can be set in the vehicle-mounted central control screen / user mobile device to enable or disable the detonation unlock (i.e., enable or disable the detonation control module 130 to generate a blasting signal). The user can turn the soft switch on or off in the vehicle-mounted central control screen / user mobile device. The vehicle-mounted central control screen / user mobile device generates different signals according to the user's on / off operation and sends them to the detonation control module 130, thereby indicating whether the detonation control module 130 generates a blasting signal.

[0052] In another exemplary embodiment, Figure 7 As shown, the collision unlocking control device also includes a second switch 160 for closing or disconnecting the connection between the detonation control module 130 and the initiator 120. Second switch 160 is disposed between the detonation control module 130 and the initiator 120. For example, the detonation control module 130 is hardwired to the initiator 120 via second switch 160. Users can close or open second switch 160 as needed to close or disconnect the connection between the detonation control module 130 and the initiator 120, thereby enabling control over communication between the two devices. When second switch 160 is closed, the initiator 120 can receive the blasting signal from the detonation control module 130 and initiate detonation. When second switch 160 is open, the initiator 120 cannot receive the blasting signal from the detonation control module 130, preventing detonation. This embodiment allows for flexible activation and deactivation of the detonation unlocking function based on user needs, improving the user experience.

[0053] See also Figure 8 , Figure 8 FIG. 1 is a schematic diagram of the hardware structure of a double unlocking mechanism collision unlocking control device according to a specific embodiment of the present application. Figure 8 As shown, the dual unlocking mechanism collision unlocking control device includes a collision sensor, an ABM, a BCM, a vehicle-mounted central control screen, and a detonator (i.e., a detonator) arranged at the ratchet of the door lock, wherein the ABM is respectively connected to the collision sensor, the vehicle-mounted central control screen, the BCM and the detonator, the collision sensor is used for collision detection, the vehicle-mounted central control screen is used to enable or disable the detonation of the door lock, the ABM is used to control the detonator detonation and communication with the BCM, and the BCM is used to control the unlocking of the door.

[0054] Figure 9 yes Figure 8 The schematic diagram of the working principle of the double unlocking mechanism collision unlocking control device in a specific embodiment is shown. Figure 9 As shown, the dual unlocking mechanism collision unlocking control device operates as follows: A soft switch on the vehicle's central control panel enables / disables the ABM detonating door locks (detonation unlocking), thereby enabling or disabling the ABM's generation of a detonation signal. For example, during a crash test, the user can disable the ABM detonation via the soft switch, allowing the ABM to transmit the collision signal received from the collision sensor to the BCM, which then performs the door unlocking, thus preventing the door locks from opening automatically after a collision and resulting in a penalty. Outside of a crash test, the user can enable the ABM detonation via the soft switch. Upon receiving the collision signal from the collision sensor, the ABM transmits a detonation signal (i.e., a detonation signal) to the detonator via a hardwire, triggering the detonator to detonate the ratchet that destroys the front door lock. This causes the latch to automatically reset under the action of a spring, allowing the door to open automatically. This solution directly controls the rapid ignition detonation of the door lock by the ABM, achieving an extremely fast detonation speed of approximately 30ms, an order of magnitude faster than the unlocking speed of the drive motor. This prevents unsuccessful door unlocking due to a rapid power outage during a collision. In addition, this solution can release the clamping plate and the door can be opened automatically even if the locking mechanism of the door lock body is deformed by directly destroying the ratchet.

[0055] In another exemplary embodiment of the present application, a vehicle is provided, including the collision unlocking control device provided in each of the aforementioned embodiments. This vehicle ensures that the doors can be unlocked promptly even in the event of a collision that causes a rapid loss of power to the power system, effectively avoiding the risk of unlocking due to power outages. Even if the doors or lock body are deformed or damaged by a collision, the explosive force of the detonator can still unlock the door. This fast and reliable unlocking mechanism ensures that occupants can quickly escape the vehicle in the event of a collision, reducing the risk of entrapment and injury, thereby improving occupant safety.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application.
