Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an active center console flip cover device and a center console armrest. Background Technology

[0002] With the continuous improvement of automotive safety standards, occupant protection in side-impact scenarios has become a key research focus in the industry. Currently, most mainstream cars use a fixed-height design for the center console armrest and the storage compartment lid, which usually only has a daily opening and closing function (such as flipping upwards or sliding open from one side) and lacks a collision protection linkage mechanism.

[0003] There are two major safety hazards in side collisions of automobiles: First, the center console armrest is too low to provide effective support for the occupant's chest. The impact force can easily cause the occupant's body to shift towards the side or center of the collision area. The corner of the center console armrest can also make rigid contact with the occupant's ribs, causing rib contusions, fractures, and other injuries (C-NCAP regulatory scoring item). Second, the driver and front passenger are prone to shift towards the center of the vehicle in a side collision, resulting in head impact. Although existing remote airbags can provide some protection for the head, the flexible structure of the airbag is difficult to provide effective lateral support. When the collision acceleration is too high, there is a risk that the head and chest will be penetrated by the airbag (one of the main difficulties of C-NCAP remote virtual evaluation).

[0004] In existing technologies, protection against side collisions is mostly focused on strengthening the vehicle body structure and increasing airbag volume, without combining the structural function of the center console armrest cover with collision protection requirements. This results in a gap in the support and protection of the occupant's far side during a side collision, making it impossible to further reduce safety risks. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an active central control flip cover device and a central control armrest. The active central control flip cover device opens instantly upon impact, causing the flip cover to stand upright and form a continuous support surface with the outer side of the armrest box. This avoids direct rigid contact between the corner of the armrest box and the occupant's ribs, disperses the impact force, and significantly reduces the probability of serious injuries such as rib contusions and fractures.

[0006] To solve the above-mentioned technical problems, on the one hand, this utility model provides an active central control flip cover device, comprising: An actuator includes a fixed part, one end of which is fixedly connected to the inner wall of the armrest box. A swing arm is mounted on the fixed part, one end of which is rotatably connected to the fixed part, and the other end of which is fixedly connected to the flip cover of the armrest box. A sliding groove is formed in the fixed part, and a gunpowder storage slot is formed at one end of the sliding groove. Gunpowder is placed in the gunpowder storage slot and connected to an ignition wire. A slider is provided at one end of the swing arm and is slidably disposed in the sliding groove. The sliding groove is used to limit the sliding range of the slider, thereby limiting the rotation angle of the swing arm. When the flip cover is closed, the slider is located at the opening of the gunpowder storage slot. The triggering device includes a collision sensor and a controller. The collision sensor is used to detect side collision signals of the vehicle, and the controller is connected to the collision sensor and the ignition wire to determine whether the ignition conditions have been met after receiving the sensor signal.

[0007] In some embodiments, one end of the swing arm is provided with a rotating shaft, the swing arm is rotatably connected to the fixed part through the rotating shaft, and the slider is fixedly disposed on the rotating shaft.

[0008] In some embodiments, the slider is in contact with the wall of the groove.

[0009] In some embodiments, both the groove and the slider are fan-shaped, the centers of the fan-shaped rings corresponding to the groove and the slider are the same, and the axis of the rotating shaft passes through the center.

[0010] In some embodiments, the end of the rotating shaft away from the swing arm passes through the fixing part and is provided with a limiting member.

[0011] In some embodiments, the limiting member is threadedly connected to and welded to the rotating shaft.

[0012] In some embodiments, the groove is formed on the side of the fixed portion near the swing arm.

[0013] In some embodiments, the gunpowder is wrapped with a sealing layer, and the sealing layer is coated with a moisture-proof coating.

[0014] In some embodiments, the sealing layer is adhered to the wall of the drug storage tank.

[0015] On the other hand, this utility model provides a central control armrest, including the aforementioned active central control flip cover device, and also includes an armrest box, wherein the armrest box is provided with two split flip covers, and the flip covers and the armrest box are rotatably connected by hinges.

[0016] The beneficial effects of this utility model are as follows: 1. This utility model uses an active central control flip cover device to instantly open the flip cover upon impact, causing the flip cover to stand up and form a continuous support surface with the outer side of the armrest box, avoiding direct rigid contact between the corner of the armrest box and the occupant's chest ribs, dispersing the impact force, and significantly reducing the probability of serious injuries such as rib contusions and fractures.

[0017] 2. The active central control flip cover device of this utility model is integrated into the root of the rotating hinge of the storage box flip cover, realizing the integration of daily opening and closing function and collision protection function. It does not require additional space in the central control area, has a compact structure and does not damage the original interior layout.

[0018] 3. When the flip cover of this utility model is erected, it can serve as a physical positioning structure to assist the remote airbag in accurately positioning the occupant's head and chest, reducing the airbag's displacement during the collision process, allowing the airbag to more fully cover the key protection area, thereby enhancing the overall protective performance.

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] like Figure 1As shown, this utility model provides a central control armrest, including an armrest box 1, on which two hinged flaps 11 are provided, as shown in the figure. Figure 3 As shown, the flip cover 11 is rotatably connected to the inner wall of the armrest box 1 via a hinge 12. There are no latches between the flip cover 11 and the armrest box 1, meaning the flip cover 11 can be freely opened and closed. The width of the flip cover 11 is 5-15cm (set according to the vehicle model and the passenger's chest protection requirements). Figures 2 to 4 As shown, an active central control flip cover device is installed inside the armrest box 1. One end of the active central control flip cover device is fixedly connected to the armrest box 1, and the other end is fixedly connected to the flip cover 11. When the vehicle is involved in a side collision, the active central control flip cover device actively opens the flip cover 11, so that the flip cover 11 stands up and forms a support surface together with the outer side of the armrest box 1, avoiding direct rigid contact between the corner edge of the armrest box 1 and the occupant's chest ribs, and significantly reducing the probability of rib contusions, fractures and other injuries.

[0023] In addition, when the flip cover 11 is raised, it can work in conjunction with the remote airbag. The raised flip cover 11 can assist the airbag in positioning the occupant's head and chest, reduce airbag offset, and make the airbag more accurately cover the protected area, thereby improving the overall protection efficiency.

[0024] The active central control flip cover device includes an actuator 2 and a triggering device.

[0025] The actuator 2 includes a fixed part 21 and a swing arm 22.

[0026] like Figure 5 As shown, the fixing part 21 is whistle-shaped and includes a column and a plate. The outer circumferential surfaces of the plate and the column are integrally formed. A mounting hole 215 is provided at the end of the plate away from the column. The mounting hole 215 is used for fixing the plate to the inner wall of the armrest box 1 (which can be fixed by bolts). Figure 6 As shown, the column is cylindrical, with a shaft hole 214 on its axis. A sliding groove 211 is provided on one end face of the column. The sliding groove 211 is fan-shaped, and its center is located on the axis of the shaft hole 214. A gunpowder storage tank 212 is provided at one end of the sliding groove 211. The gunpowder is placed in the gunpowder storage tank 212 and is covered with a sealing layer. The sealing layer is coated with a moisture-proof coating and is adhered to the tank wall of the gunpowder storage tank 212. An ignition wire interface 213 is provided on the column.

[0027] like Figure 5 As shown, a swing arm 22 is provided on the fixed part 21, such as Figure 7As shown, a rotating shaft 23 is fixedly installed at one end of the swing arm 22. The rotating shaft 23 is perpendicular to the swing arm 22. One end of the rotating shaft 23 is inserted into the shaft hole 214 and rotatably connected to the fixing part 21. The other end of the swing arm 22 is used to fix the flip cover 11 (which can be fixed by bolts). A slider 231 is installed on the rotating shaft 23. The slider 231 can be fixed to the rotating shaft 23 by welding. The slider 231 is located in the slide groove 211. The slider 231 is fan-shaped. The center of the corresponding fan ring of the slide groove 211 and the slider 231 are the same. The slider 231 fits against the groove wall of the slide groove 211, so that when the rotating shaft 23 rotates, the slider 231 can rotate with the rotating shaft 23 and slide relative to the groove wall of the slide groove 211.

[0028] It should be noted that the connection between the slider 231 and the rotating shaft 23 should be strong enough to prevent the high-pressure gas generated by the gunpowder from breaking the connection. Specifically, its strength can be increased by checking the welding quality, increasing the thickness of the slider 231, and increasing the diameter of the rotating shaft 23.

[0029] The groove 211 is formed on the end face of the fixed part 21 near the swing arm 22. The end of the rotating shaft 23 away from the swing arm 22 passes through the fixed part 21 and is provided with a limiting member 232. The limiting member 232 is made of bolt. The limiting member 232 and the rotating shaft 23 are connected by threads and welded together. A gap is provided between the limiting member 232 and the fixed part 21. The limiting member 232 can restrict the rotating shaft 23 in the shaft hole 214 without affecting the normal rotation of the rotating shaft 23.

[0030] like Figure 8 As shown, the central angle of the slide groove 211 is 180° and the central angle of the slider 231 is 90°. When the flip cover 11 is closed, the slider 231 is located at the opening of the medicine storage tank 212. When the slider 231 rotates 90° along the slide groove 211, the flip cover 11 rotates from the closed state to the vertically open state, which does not affect the normal opening and closing of the flip cover 11.

[0031] The triggering device includes a collision sensor and a controller. The collision sensor is used to detect side collision signals of the vehicle (such as collision acceleration, impact force, etc.). The controller is connected to the collision sensor and the ignition wire. The collision trigger threshold is pre-stored in the controller. After receiving the collision sensor signal, the controller determines whether the ignition condition is met. If the condition is met, it sends an execution command to the actuator 2.

[0032] The working principle of this active central control flip cover device is as follows: Under normal conditions, the pivot 23 can rotate freely, and its function is the same as that of the hinge 12, which does not affect the normal use of the flip cover 11. When a car is involved in a side collision, the collision sensor detects that the collision acceleration, impact force and other signals exceed the preset threshold, and immediately converts the collision signal into an electrical signal and transmits it to the controller. After receiving the electrical signal, the controller completes signal analysis and threshold comparison within 10ms, confirms that the triggering conditions are met (excluding false triggering in non-collision scenarios such as road bumps and minor scratches), and sends an ignition command to the actuator 2. After receiving the command, the actuator 2 ignites the gunpowder in the gunpowder reservoir 212 via the ignition wire. The generated gas pushes the slider 231 to rotate the shaft 23 by 90°, and at the same time, it rotates the flip cover 11 by 90°, causing the flip cover 11 to open automatically. The opening process of the flip cover 11 takes no more than 50ms, ensuring that the height of the center console armrest is raised before the occupant's body shifts significantly. After the flip cover 11 is opened, the high-temperature and high-pressure gas in the gunpowder reservoir 212 and the slide 211 provides pressure support to the slider 231, ensuring that the flip cover 11 can form an effective support surface when open. On the one hand, the open flip cover 11 prevents the occupant's chest from making direct rigid contact with the corner of the center console, reducing the risk of rib injury. On the other hand, the physical blocking structure reduces the amount of displacement of the driver and occupant towards the center of the vehicle. At the same time, for vehicles equipped with remote airbags, it can also work in conjunction with the deployment of the remote airbag, working together with the open flip cover 11 to provide dual protection for the occupant's head and chest.

[0033] It should be noted that when a vehicle is involved in a side collision, the entire collision time is usually less than 150ms. Therefore, the gunpowder should be able to burn gradually and continuously produce gas within 150ms, so that the storage tank 212 and the slide 211 are always filled with high-temperature and high-pressure gas, ensuring that the flip cover 11 always provides effective support for personnel during this period.

[0034] In addition, multiple active central control flip devices can be set for each flip cover 11 to ensure stable support of the flip cover 11.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
