[0026] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
[0027] Please refer to the following Figure 1 A vehicle door hinge structure 100 according to an embodiment of the present invention is described.
[0028] Reference Figure 1 According to an embodiment of the present invention, a vehicle door hinge structure 100 includes: a vehicle door hinge, an electromagnetic lock 10 and a collision sensor. The vehicle door hinge is used to connect the vehicle door and the vehicle body; the electromagnetic lock 10 has a locked state and an unlocked state. In the locked state, the electromagnetic lock 10 locks the vehicle door hinge. In the unlocked state, the electromagnetic lock 10 releases the vehicle door hinge so that the vehicle door can be opened; the electromagnetic lock 10 is electrically connected to the collision sensor and is configured to switch between the unlocked state and the locked state according to the collision sensor.
[0029] During normal vehicle use, when a door needs to be opened, the electromagnetic lock 10 switches from a locked state to an unlocked state, releasing the door hinges and allowing the door to open. When the door needs to be closed, the door is in a closed position relative to the vehicle body, and the electromagnetic lock 10 switches from an unlocked state to a locked state, locking the door hinges and closing the door. If the vehicle is involved in a collision, the collision sensor detects a collision signal, and the electromagnetic lock 10 switches from a locked state to an unlocked state based on the collision signal. At this point, the electromagnetic lock 10 releases the door hinges, opening the door and allowing occupants to escape.
[0030] The vehicle door hinge structure 100 of the present invention is provided with an electromagnetic lock 10. When the vehicle is involved in a collision, the electromagnetic lock 10 switches from a locked state to an unlocked state according to a collision signal. The electromagnetic lock 10 actively releases the door hinge, the door opens, and the occupants of the vehicle can escape from the vehicle, thereby protecting the life safety of the occupants and improving the safety performance of the vehicle. At the same time, the electromagnetic lock 10 controls the door opening, which can increase the door opening speed, thereby reducing the time it takes for the occupants to escape from the vehicle, thereby ensuring the safety of the occupants in the vehicle. In addition, when the vehicle is not involved in a collision, the electromagnetic lock 10 locks the door hinge, thereby ensuring that the door can be closed normally, thereby ensuring the normal operation of the vehicle.
[0031] According to the vehicle door hinge structure 100 of the embodiment of the present invention, an electromagnetic lock 10 is provided, and the electromagnetic lock 10 actively releases the vehicle door hinge, so that the passengers in the vehicle can escape from the vehicle, thereby reducing the time for the passengers to escape from the vehicle, ensuring the life safety of the passengers in the vehicle, and improving the safety performance of the vehicle.
[0032] According to some embodiments of the present invention, referring to Figure 1 One of the electromagnetic lock 10 and the door hinge is provided with a lock catch, and the other is provided with a lock hole. In other words, the electromagnetic lock 10 can be provided with a lock catch and the door hinge is provided with a lock hole, or the door hinge can be provided with a lock catch and the electromagnetic lock 10 is provided with a lock hole, with the lock catch and the lock hole cooperating. This simplifies the cooperating structure of the lock catch and the lock hole, making it easier for the electromagnetic lock 10 to lock or release the door hinge, thereby improving the response speed of the electromagnetic lock 10 cooperating with the door hinge.
[0033] According to some embodiments of the present invention, referring to Figure 1 The vehicle door hinge structure 100 includes an explosive bolt 20 connected to the vehicle door hinge. Upon being triggered, the explosive bolt 20 is configured to separate the door hinge from the vehicle body. The explosive bolt 20 is electrically connected to a collision sensor. Thus, if a vehicle is severely deformed in a collision, rendering the door unable to open, the explosive bolt 20 activates to separate the door hinge from the vehicle body, thereby allowing occupants to escape and thus ensuring their safety.
[0034] According to some embodiments of the present invention, referring to Figure 1 The door hinge structure 100 also includes: a control circuit 30, the control circuit 30 includes: a power supply 31, a first branch 32, a second branch 33 and a control switch 36, the electromagnetic lock 10 is connected in series to the first branch 32, the explosive bolt 20 is connected in series to the second branch 33, and the control switch 36 is used to control the conduction and disconnection of the power supply 31 and the first branch 32 and the second branch 33.
[0035] In this way, the power supply 31 can provide power to the control circuit 30, and the first branch 32 and the second branch 33 are both connected to the power supply 31, so that the electromagnetic lock 10 and the explosive bolt 20 can be normally activated. The control switch 36 can control the conduction and disconnection of different branches, so that the corresponding branch can be selected for conduction based on the collision signal of the collision sensor. In addition, the provision of the control circuit 30 allows the electromagnetic lock 10 and the explosive bolt 20 to be controlled by the control circuit 30, thereby reducing the response time of the electromagnetic lock 10 or the explosive bolt 20, thereby saving the time required for the occupants to open the door and improving the safety performance of the vehicle.
[0036] According to some optional embodiments of the present invention, referring to Figure 1 The control circuit 30 further includes a third branch 34, one end of which is grounded and the other end of which is adapted to be connected to the power supply 31 via a control switch 36. Thus, the third branch 34 is provided so that, after the collision sensor receives a collision signal from the vehicle, the control switch 36 is connected to the third branch 34, the electromagnetic lock 10 is de-energized, and the electromagnetic lock 10 releases the door hinge, thereby allowing the door to open normally.
[0037] According to some optional embodiments of the present invention, referring to Figure 1 The control switch 36 is a single-pole triple-throw switch, and the power supply 31 is switchably connected to the first branch 32, the second branch 33, and the third branch 34. Thus, the single-pole triple-throw switch can simplify wiring and control the power supply 31 to be connected to three different circuits, thereby enabling the activation of different electrical components.
[0038] According to some embodiments of the present invention, referring to Figure 1 The control circuit 30 includes a first fuse resistor 37 connected in series with the second branch 33. This prevents accidental triggering of the explosive bolt 20 during vehicle repair and maintenance, thereby avoiding waste of resources. During vehicle repair and maintenance, the first fuse resistor 37 is removed, disconnecting the second branch 33 and preventing accidental triggering of the explosive bolt 20.
[0039] According to some embodiments of the present invention, referring to Figure 1 The control circuit 30 includes a fourth branch 35 and a capacitor 38. One end of the fourth branch 35 is grounded, and the other end is connected between the power supply 31 and the control switch 36. The capacitor 38 is connected in series with the fourth branch 35 and is used to power the explosive bolt 20. Therefore, in the event of a vehicle collision, the capacitor 38 can ensure that the explosive bolt 20 can be properly activated, thereby ensuring that the door and the body can be properly separated.
[0040] According to some optional embodiments of the present invention, referring to Figure 1The control circuit 30 further includes a second safety resistor 39 connected in series with the fourth branch 35. Thus, the second safety resistor 39 is provided to protect the capacitor 38 during the charging process of the capacitor 38, thereby ensuring the safe use of the capacitor 38.
[0041] According to the second embodiment of the present invention, the vehicle Figure 1 , including: a vehicle door, a vehicle body and the vehicle door hinge structure 100 of the first aspect of this embodiment, the vehicle door is connected to the vehicle body through the vehicle door hinge structure 100.
[0042] According to the vehicle of the embodiment of the present invention, by setting the door hinge structure 100 of the above-mentioned first embodiment and setting the electromagnetic lock 10, the electromagnetic lock 10 actively releases the door hinge, and the passengers in the vehicle can escape from the vehicle, thereby reducing the time for the passengers to escape from the vehicle, ensuring the life safety of the passengers in the vehicle, and improving the safety performance of the vehicle.
[0043] Furthermore, the vehicle also includes: a collection module, a data storage module, a calculation module and a comparison module.
[0044] The acquisition module collects door data to determine the current vehicle status. It includes high-precision sensors: strain sensors and displacement sensors are installed at key locations on the door, such as the frame and panel, to measure door deformation and position changes in real time. While the vehicle is in operation, the sensors continuously collect data from the door in various states, including normal driving, minor bumps, parking, and other non-collision situations, as well as data from various collision simulations. The collected data undergoes pre-processing, such as filtering and noise reduction, to improve accuracy.
[0045] The data storage module is used to store the current door status data.
[0046] The calculation module uses preprocessed data to build a deformation model for the door under different collision intensities. Finite element analysis and other methods can be used to determine the mathematical relationship between door deformation and collision energy, taking into account factors such as the door's material properties, structural characteristics, and collision angle.
[0047] The comparison module monitors sensor data in real time while the vehicle is in motion. It calculates door deformation, such as strain and displacement, and compares this data with the deformation model. Crash intensity assessment: Based on the matching results between the deformation and the deformation model, a quantitative assessment of the collision intensity is performed. Different levels can be set, such as mild collision (small deformation), moderate collision (moderate deformation), and severe collision (large deformation). A comprehensive assessment can also be made based on changes in vehicle speed and acceleration, as well as sensor data from other locations.
[0048] For example, through experiments and modeling, it is concluded that a door displacement of more than 5 cm and a strain of more than 0.1 is defined as a severe collision, a displacement of 2-5 cm and a strain between 0.05-0.1 is defined as a moderate collision, and a displacement of less than 2 cm and a strain less than 0.05 is defined as a mild collision.
[0049] When the vehicle is running, the door hinge structure 100 is opened. The specific control process of the door hinge structure 100 is as follows:
[0050] The vehicle feeds back current status signal information such as vehicle speed and information collected by the acquisition module to the data storage module. Collision sensors, pressure sensors, etc. installed in key parts of the vehicle detect and transmit in real time, and feeds back the thresholds set in the data storage module and collision history information to the calculation module. The calculation module analyzes and processes this information to obtain a data model for the current status and whether a collision has occurred. The comparison module compares the received signal with the obtained data model to determine the severity of the collision.
[0051] When the vehicle operates normally, the single-pole triple-throw switch is connected to the first branch 32 , and the electromagnetic lock 10 operates normally.
[0052] When the collision sensor transmits the collision signal to the calculation module, if the vehicle has a light collision, the door is slightly deformed, and a trigger instruction is sent to the electromagnetic lock 10. At this time, Figure 1 The single-pole triple-throw switch shown is disconnected from the first branch 32 and connected to the third branch 34. At the same time, the status signal of the electromagnetic lock 10 is fed back to the data storage module, the power supply 31 is disconnected from the electromagnetic lock 10, and the electromagnetic lock 10 releases the door hinge, so that the door can be opened.
[0053] If the vehicle is involved in a moderate or severe collision, the door cannot be opened normally even if the electromagnetic lock 10 is disconnected. Figure 1 The single-pole triple-throw switch shown is disconnected from the third branch 34 and connected to the second branch 33. The power supply 31 and the capacitor 38 are electrically connected to the explosive bolt 20. The explosive bolt 20 is activated, and the explosive bolt 20 disconnects the door hinge, separating the door from the vehicle body, allowing the occupants in the vehicle to escape from the vehicle.
