[0036] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0037] Reference below Figure 1-Figure 11 The accelerator pedal device 100 according to the embodiment of the present invention is described, which can achieve the separation effect without destroying its own structure, thereby reducing accident hazards and improving recycling rate.

[0038] Combination Figure 1-Figure 9 As shown, the accelerator pedal device 100 according to the first aspect of the embodiment of the present invention includes a base 10, a first pedal arm 20, a second pedal arm 30 and an electromagnetic locking assembly 40, one end of the first pedal arm 20 is rotatably arranged on the base 10, the other end of the first pedal arm 20 is provided with a mounting groove 21, one end of the second pedal arm 30 is arranged in the mounting groove 21, and one end of the second pedal arm 30 is provided with a locking matching portion 31, the other end of the second pedal arm 30 is provided with a pedal surface 32, the electromagnetic locking assembly 40 is arranged on the first pedal arm 20, the electromagnetic locking assembly 40 includes: an electromagnetic member 41 and a magnetic locking member 42, the electromagnetic member 41 and the magnetic locking member 42 are arranged at intervals, the magnetic locking member 42 is locked and matched with the locking matching portion 31, the electromagnetic member 41 in the power-on state magnetically acts on the magnetic locking member 42 to release the lock of the magnetic locking member 42 and the locking matching portion 31, so that one end of the second pedal arm 30 is disengaged from the mounting groove 21.

[0039] Specifically, the base 10, the first pedal arm 20 and the second pedal arm 30 are connected in sequence. The base 10 is connected and fixed to the vehicle body, and serves as a supporting carrier for the accelerator pedal device 100 to be installed on the vehicle body. One end of the first pedal arm 20 can rotate relative to the base 10, and one end of the second pedal arm 30 is connected to the other end of the first pedal arm 20. One end of the second pedal arm 30 is a pedal surface 32. In this way, the driver can step on the pedal surface 32 with different forces to make the second pedal arm 30 indirectly connected to it rotate at different angles relative to the base 10, thereby achieving control effects of different throttle sizes.

[0040] Furthermore, the mounting groove 21 at the other end of the first pedal arm 20 and the locking fitting portion 31 at one end of the second pedal arm 30 can be selectively locked and matched. When the entire vehicle is in a normal state, the locking fitting portion 31 on the second pedal arm 30 is locked and matched with the magnetic locking member 42 on the first pedal arm 20, so that the locking fitting portion 31 can be clamped in the mounting groove 21 of the first pedal arm 20 to prevent the second pedal arm 30 from falling off, thereby achieving a stable connection of the accelerator pedal device 100 and thus realizing the driver's stepping acceleration operation; when the entire vehicle detects a vehicle accident and triggers the fracture condition of the accelerator pedal device 100, the electromagnetic member 41 is energized and generates an electromagnetic force on the magnetic locking member 42, and the magnetic locking member 42 is disengaged from the lock under the action of the electromagnetic force. The second pedal arm 30 is moved in the direction of the locking fitting portion 31. When the magnetic locking piece 42 moves out of the locking fitting portion 31 of the second pedal arm 30, the second pedal arm 30 falls off from the mounting groove 21 of the first pedal arm 20, thereby achieving the effect of self-separation without damaging the accelerator pedal device 100, thereby avoiding the related hidden dangers caused by the accelerator pedal device 100 when a vehicle accident occurs; and when the electromagnetic member 41 stops being energized, the magnetic locking piece 42 can be restored to the original locking position under the action of external force, and the second pedal arm 30 can be reassembled into the first pedal arm 20. When the magnetic locking piece 42 is stuck in the locking fitting portion 31, the reassembly of the accelerator pedal device 100 is completed at this time, so that the accelerator pedal device 100 can continue to be used normally, thereby reducing the vehicle maintenance cost.

[0041] Therefore, by designing the device, when a vehicle accident occurs, the second pedal arm 30 can be separated from the base 10 without damaging its own structure, thereby reducing the risk of the accident.

[0042] According to some optional embodiments of the present invention, Figure 3 and Figure 7 As shown, the locking matching portion 31 is a locking groove, and the magnetic locking member 42 is configured as a locking block, and the locking block at least partially extends into the locking groove. Specifically, the locking matching portion 31 and the magnetic locking member 42 are respectively configured as a locking groove and a locking block that can be locked with each other, so that the second pedal arm 30 and the first pedal arm 20 can be locked and matched under the action of external force and connected as a whole, thereby realizing the normal stepping acceleration function of the accelerator pedal device 100. Among them, the locking block at least partially extends into the locking groove, so that the locking block can complete the locking and matching effect with the locking matching portion 31, and it is also convenient for the locking block to have a size margin to match other adjacent structures, thereby improving the practicality and scientific arrangement of the locking block.

[0043] According to some optional embodiments of the present invention, Figure 3 , Figure 4 and Figure 7As shown, the electromagnetic locking assembly 40 further includes a first elastic member 43 , which abuts between the first pedal arm 20 and the magnetic locking member 42 to provide elastic force for the magnetic locking member 42 to lock and cooperate with the locking cooperation portion 31 . Specifically, the first elastic member 43 abuts between the first pedal arm 20 and the magnetic locking member 42. When the vehicle is in a normal state, the first elastic member 43 is in a natural state or a slightly compressed state. When the magnetic locking member 42 moves toward one side of the first elastic member 43, the magnetic locking member 42 squeezes the first elastic member 43, and the first elastic member 43 generates an elastic force in the opposite direction, thereby ensuring the locking stability of the magnetic locking member 42 and the locking matching portion 31 in a normal state; when the vehicle detects a vehicle accident and triggers the rupture condition of the accelerator pedal device 100, the electromagnetic member 41 is energized to generate an electromagnetic force, and the electromagnetic force generates an external force on the first elastic member 43. The first elastic member 43 elastically deforms toward one side away from the locking matching portion 31, and the elastic force overcome by the electromagnetic force is less. In this way, the magnetic locking member 42 connected to the first elastic member 43 can be unlocked from the locking matching portion 31 more quickly, thereby improving the response speed of the magnetic locking member 42 unlocking from the locking matching portion 31, thereby reducing the harmfulness of the vehicle after an accident.

[0044] Specifically, combined Figure 3 , Figure 4 and Figure 7 As shown, the electromagnetic member 41 is an electromagnetic coil, which is sleeved on the outside of the first elastic member 43. The electromagnetic coil is established by the existence of a magnetic field around the wire when current passes through it. Winding it into a spiral shape can strengthen the magnetic field. When the electromagnetic coil is energized, the electromagnetic coil is equivalent to an electromagnet, and the polarity of the magnetic field formed at one end close to the magnetic locking member 42 is different from the polarity of the magnetic field at one end of the magnetic locking member 42 close to the electromagnetic coil. In this way, an electromagnetic force is formed on the magnetic locking member 42 to overcome the elastic force of the first elastic member 43 and move in the direction of disengaging from the locking matching portion 31, thereby smoothly achieving the breaking and separation effect of the accelerator pedal device 100.

[0045] According to some optional embodiments of the present invention, Figure 3 , Figure 4 and Figure 7 As shown, there are at least two electromagnetic locking assemblies 40, and at least two electromagnetic locking assemblies 40 are arranged on opposite sides of the first pedal arm 20. Specifically, at least two electromagnetic locking assemblies 40 are correspondingly arranged on opposite sides of the first pedal arm 20. Compared with a single electromagnetic locking assembly 40, the locking force points and force directions of the magnetic locking member 42 and the locking matching portion 31 can be increased, and the locking contact area of ​​the magnetic locking member 42 and the locking matching portion 31 can also be increased, thereby improving the locking stability and the force uniformity of the locking connection, thereby improving the practicality and reliability of the accelerator pedal device 100.

[0046] According to some optional embodiments of the present invention, Figure 3 , Figure 4 , Figure 7 and Fig. 9 As shown, the accelerator pedal device 100 also includes a second elastic member 50, which abuts against the bottom wall of the mounting groove 21 and the top of one end of the second pedal arm 30. When the magnetic locking member 42 and the locking matching portion 31 are unlocked, the second elastic member 50 provides elastic force for one end of the second pedal arm 30 to escape from the mounting groove 21.

[0047] Specifically, the second elastic member 50 abuts against the bottom wall of the mounting groove 21 and the top of one end of the second pedal arm 30. When the whole vehicle is in a normal state, the second elastic member 50 is in a compressed state. At this time, the second elastic member 50 generates an elastic force on the top of the second pedal arm 30 in a direction away from the first pedal arm 20, but the elastic force is not enough to overcome the combined force that puts the second pedal arm 30 in a locked state, thereby ensuring the locking stability of the magnetic locking member 42 and the locking matching portion 31 in a normal locked state. When the whole vehicle detects a vehicle accident and triggers the acceleration When the pedal device 100 is in a breaking condition, the electromagnetic component 41 is energized to generate electromagnetic force, and the magnetic locking component 42 moves toward the side away from the locking matching part 31 under the action of the electromagnetic force. At this time, the locking matching part 31 on the second pedal arm 30 is no longer subject to the locking force from the magnetic locking component 42. In this way, the second pedal arm 30 can be quickly detached from the mounting groove 21 of the first pedal arm 20 under the action of the elastic force of the second elastic component 50, thereby improving the response speed of the accelerator pedal device 100 when it is separated and broken, and then reducing the harm to the vehicle after an accident.

[0048] Combination Figure 3 and Fig.10 As shown, the control method of the accelerator pedal device 100 according to the second embodiment of the present invention includes the following steps: determining whether the vehicle meets the preset conditions; if so, controlling the electromagnetic component 41 to be energized so that the electromagnetic component 41 and the magnetic locking component 42 magnetically interact with each other, and the magnetic locking component 42 and the locking matching part 31 are unlocked, thereby allowing one end of the second pedal arm 30 to disengage from the mounting groove 21.

[0049] Specifically, the vehicle can use a video monitoring system including an image acquisition module, such as a camera, to acquire image information of the corresponding area outside the vehicle, and can also use a pressure sensing system to acquire force information of the corresponding area of ​​the vehicle, so as to determine whether the vehicle condition at this time meets the conditions for the accelerator pedal device 100 to be separated and broken by acquiring vehicle information, so as to match the locking or unlocking state of the magnetic locking member 42 and the locking matching portion 31 at this time according to the judgment result, thereby improving the intelligence and practicality of the accelerator pedal device 100. Among them, the vehicle is controlled by electronic signals in the process of automatically identifying whether an accident has occurred and analyzing and determining whether the accelerator pedal device 100 needs to be disconnected, thereby effectively improving the response speed.

[0050] According to some optional embodiments of the present invention, Fig.11 As shown, the preset conditions include: the vehicle's airbag is opened; and / or it is determined that the vehicle has collided, and the collision position is at least one of the front, left and right sides, and the collision acceleration is not less than a preset threshold. Specifically, when the vehicle detects that the airbag is opened, the vehicle cannot continue to drive at this time, and the vehicle reaches the preset condition of the accelerator pedal device 100 breaking, so that the second pedal arm 30 is automatically disconnected from the first pedal arm 20; when the vehicle is driving, the front or any of the two sides of the vehicle collides, and the collision acceleration is not less than a preset threshold, the vehicle reaches the preset condition of the accelerator pedal device 100 breaking, so that the second pedal arm 30 is automatically disconnected from the first pedal arm 20; otherwise, the accelerator pedal device 100 is maintained in an integrated connection state, thereby improving the practicality and intelligence of the accelerator pedal device 100.

[0051] In detail, when a vehicle collides, according to Newton's third law (force is mutual), the force applied by the user to the accelerator pedal device 100 will also be converted into a reaction force applied by the accelerator pedal device 100 to the user. In order to prevent the accelerator pedal device 100 from causing harm to the user, according to data calculation, the preset threshold value of the acceleration during a frontal collision of the vehicle does not exceed 20m / s2 (calculated based on an adult weighing 75kg, the accelerator pedal device 100 needs to automatically break before being subjected to an acceleration of 2g, and the reaction force of the accelerator pedal device 100 on the person under this collision force will not cause significant harm). For example, when the preset threshold value is 15m / s2, the acceleration generated at the moment of the frontal collision of the vehicle is 17m / s2, which exceeds 15m / s2, and the accelerator pedal device 100 automatically disconnects at this time, thereby preventing the driver from being harmed by the accelerator pedal device 100.

[0052] According to some optional embodiments of the present invention, Fig.11As shown, when determining that the vehicle has collided, the following steps are also included: detecting whether there is a driver in the driving seat; if not, controlling the electromagnetic component 41 to be non-energized. Specifically, when the vehicle collides, the vehicle detects and determines whether there is a driver in the driving seat, so that the judgment condition of the accelerator pedal device 100 breaking can be further refined. When there is no driver in the driving seat, the accelerator pedal device 100 is not subject to human operation, so there is no need to break, thereby avoiding the problem of the accelerator pedal device 100 being separated by mistake, and improving its intelligence and practicality. For example, when the vehicle is started, the pressure sensor of the main driver's seat pre-detects the driver's presence information. When it is detected that the main driver is carrying a driver, the vehicle's sensor monitoring system obtains and analyzes the collision position of the vehicle when the accident occurs. When it is detected that the collision position of the vehicle is located on the non-rear side, the vehicle's speed sensor system obtains the collision acceleration of the vehicle when the accident occurs and compares it with a preset threshold. When it is detected that the collision acceleration of the vehicle is not less than the preset threshold, at this time, on the basis of simultaneously satisfying the above three conditions, the accelerator pedal device 100 fracture condition is triggered, and the electromagnetic component When the accelerator pedal 100 is powered on, the magnetic locking member 42 is disengaged from the locking fitting portion 31 under the action of the electromagnetic force, and the second pedal arm 30 is disengaged from the mounting groove 21 of the first pedal arm 20. Otherwise, the connection state of the accelerator pedal device 100 is maintained. In this way, the accelerator pedal device 100 can be disconnected in an emergency without damaging the accelerator pedal device 100, thereby avoiding the related hidden dangers caused by the accelerator pedal device 100 when a vehicle accident occurs. Moreover, the accelerator pedal device 100 can still be reassembled after being disconnected, and the function of the accelerator pedal device 100 after assembly is not affected, thereby reducing the vehicle maintenance cost. For another example, when the vehicle is started, and when an accident occurs in the vehicle and the airbag is detected to be deployed, the vehicle can no longer continue to drive, and the accelerator pedal device 100 is automatically disconnected, so that the accelerator pedal device 100 can be prevented from being stuck at the maximum opening and causing the vehicle to accelerate out of control. At the same time, after the accelerator pedal device 100 is broken in time, it can also prevent the accelerator pedal device 100 from hurting the driver's feet and legs, thereby improving the protection of the driver.

[0053] The vehicle according to the third aspect of the present invention includes the accelerator pedal device 100 of the above-mentioned embodiment. With such arrangement, the vehicle having the accelerator pedal device 100 can achieve the effect of separating its own structure without destroying its own structure, thereby reducing the risk of accidents; and the accelerator pedal device 100 can be recycled and reassembled and continue to be used normally, thereby reducing the vehicle maintenance cost.
