Description

Technical Field

[0001] This application relates to the field of transportation equipment technology, and in particular to a hinge mechanism, a spring-loaded device, and a vehicle. Background Technology

[0002] When pedestrians collide with vehicles such as cars, they are likely to hit the front of the vehicle with their legs as the center, and their heads are likely to hit the engine hood, or even have a secondary collision with hard parts such as the engine under the engine hood, resulting in more serious head injuries, or even death due to head impact.

[0003] Vehicles are generally equipped with a pop-up device. In the event of a collision, the hinge mechanism inside the pop-up device can lift one end of the engine hood, increasing the space between the engine hood and the engine. This provides pedestrians with sufficient buffer space to effectively reduce head injuries and also prevents their heads from making hard contact with components inside the engine compartment.

[0004] However, existing hinge mechanisms have the drawback of being difficult to reset after popping out, which makes the reuse process of the hinge mechanism cumbersome and the use cost of the hinge mechanism high. Utility Model Content

[0005] This application provides a hinge mechanism, a pop-up device, and a vehicle. The hinge mechanism includes a first link, a second link, and a drive rod connected to each other. When the drive rod is subjected to force, it can drive the first and second links to rotate accordingly, realizing the pop-up and / or reset process of the hinge mechanism. The pop-up or reset process can be achieved by changing the force on the drive rod, which is easy to control and improves the repeatability of the hinge mechanism's operation. Moreover, the internal structure of the hinge mechanism is simple, and the use and control cost of the hinge mechanism is low.

[0006] In a first aspect, this application provides a hinge mechanism applied to a vehicle. The hinge mechanism includes a first link, a second link, and a drive rod. The first link includes a first end and a second end, the first end being rotatably connected to a first structural member of the vehicle. The second link includes a third end and a fourth end, the third end being rotatably connected to the second end, and the fourth end being located on the side of the third end closer to the first end, the fourth end being rotatably connected to a second structural member of the vehicle. The drive rod includes a fifth end and a sixth end, the fifth end being drively connected to the first link, and the sixth end being located on the side of the fifth end closer to the first end and on the side of the first link opposite to the second link.

[0007] The sixth end is used to receive a first force, and the driving rod rotates around the sixth end in a first rotation direction to drive the first connecting rod to rotate around the first end. The second connecting rod moves with the second end and rotates around the second end, and the fourth end moves away from the first end. The sixth end is also used to receive a second force, and the driving rod rotates around the sixth end in a second rotation direction, which is opposite to the first rotation direction, to drive the first connecting rod to rotate around the first end. The second connecting rod moves with the second end and rotates around the second end, and the fourth end moves towards the first end.

[0008] Understandably, a hinge mechanism can have an extended state and a retracted state. When the fourth end moves away from the first end, the hinge mechanism is considered to switch from the retracted state to the extended state. When the fourth end moves closer to the first end, the hinge mechanism is considered to switch from the extended state to the retracted state.

[0009] In this embodiment, by setting the connection relationship between the first link, the second link, and the drive rod within the hinge mechanism, when the sixth end is subjected to a first force, the hinge mechanism can expand from the retracted state to the pop-out state; when the sixth end is subjected to a second force, the hinge mechanism retracts from the pop-out state to the retracted state. By changing the force on the sixth end of the drive rod, the opening and closing state of the hinge mechanism can be changed, making the pop-out or retraction process of the hinge mechanism simple, easy to control and change, with high repeatability of the action. Furthermore, the structure within the hinge mechanism is simple, and the use and control cost of the hinge mechanism is low.

[0010] In some possible implementations, the first connecting rod has a first sliding groove, which includes a first position and a second position. The first position is located on the side of the second position closer to the first end. The fifth end is provided with a slider, which is installed in the first sliding groove and can move between the first position and the second position. By installing the slider in the first sliding groove, when the slider moves within the first sliding groove, it can drive the first connecting rod to move together with the slider, thus realizing the transmission connection between the fifth end and the first connecting rod. The transmission structure between the drive rod and the first connecting rod is simple, with fewer parts, which helps to reduce the structural complexity and manufacturing cost of the hinge mechanism.

[0011] In some possible implementations, the first sliding groove is either a straight groove or a curved groove. By setting the first sliding groove to be a straight groove or a curved groove, it is ensured that when the slider moves within the first sliding groove, it can drive the first connecting rod to move.

[0012] In some possible implementations, the first sliding groove is a straight groove, the first connecting rod rotates about a first rotation center at the first end, and the second connecting rod rotates about a second rotation center at the second end; the extension direction of the first sliding groove is parallel to the line connecting the first rotation center and the second rotation center.

[0013] By setting the extension direction of the first sliding groove, it is beneficial to make full use of the space between the first rotation center and the second rotation center, so that the slider can move a longer path in a limited space, thereby driving the first link and the second link to move a longer stroke, effectively improving the lifting effect of the fourth end in the hinge mechanism.

[0014] In some possible implementations, the drive rod, the first link, and the second link are all plate-like structures, with the first link stacked between the second link and the drive rod. By setting the drive rod, the first link, and the second link to be plate-like structures and stacked, it is beneficial to improve the smoothness of the hinge mechanism's movement and avoid interference between the components within the hinge mechanism.

[0015] In some possible implementations, the hinge mechanism also includes a locking element located between the second end and the third end, which has a locked state and an unlocked state; when the locking element is in the locked state, it locks the second end and the third end, fixing them relative to each other; when the locking element is in the unlocked state, it unlocks the second end and the third end.

[0016] By setting a locking element, the relative movement of the second end and the third end can be selectively allowed, so that when the movement of the hinge mechanism is not required, the relative position of the second end and the third end is locked, ensuring the stability of the position of the hinge mechanism when it is in the retracted state.

[0017] In some possible implementations, the first link has a second sliding groove located at a second end and connected to the first sliding groove; the second sliding groove has a third position located on the side of the second position away from the first position, and the slider can move between the second and third positions; a locking member is provided corresponding to the third position, the locking member is in a locked state when the slider is in the third position, and in an unlocked state when the slider leaves the third position. By setting the locking member to correspond to the third position, the hinge mechanism switches between the locked and unlocked states as the slider's position changes, making the locking and unlocking process of the hinge mechanism simple to implement and easy to control.

[0018] In some possible implementations, the second sliding groove is an arc groove. By setting the second sliding groove to an arc groove, when the slider moves within the second sliding groove, the first and second connecting rods within the hinge mechanism remain relatively stationary, and the hinge mechanism remains in a retracted state. This helps ensure the stability of the relative positions of the second and third ends during unlocking or locking, thereby ensuring that the locking effect of the locking member is the same each time, supporting the reuse of the locking member, and improving the repeatability of the hinge mechanism's actions.

[0019] In some possible implementations, the second end is provided with a limiting hole, which connects to the third position of the second sliding groove. The third end is provided with a locking hole, and the locking element includes a moving block and an elastic element. When the slider is in the third position, it abuts against one end of the moving block that extends into the limiting hole, and the other end of the moving block extends into the locking hole. The elastic element is compressed, and the locking element is in a locked state. When the slider leaves the third position, it separates from the moving block, and the moving block disengages from the locking hole under the elastic force of the elastic element.

[0020] By setting an elastic element, the unlocking and locking process is realized by the cooperation between the elastic element and the slider. It is simple and easy to implement, which helps to simplify the structure of the locking element. Moreover, the hinge mechanism provided in this application embodiment does not require an additional device to control the unlocking and locking process of the locking element, which helps to reduce the structural complexity and manufacturing cost of the hinge mechanism, as well as improve the reusability of the hinge mechanism and reduce the operational difficulty of reusing the hinge mechanism.

[0021] In some possible implementations, the locking element further includes a fixed cover, which is fixed to the second end. The fixed cover has a receiving space and a through hole. The receiving space is located between the fixed cover and the second end, and the through hole connects the receiving space with the external space of the fixed cover. The elastic element is located within the receiving space. When the locking element is in the locked state, the elastic element abuts against one end of the moving block and the fixed cover, and the other end of the moving block passes through the through hole and extends into the locking hole. By providing the fixed cover, the locking element can be fixed to the first connecting rod, which improves the reliability and stability of the connection between the locking element and the first connecting rod, and improves the stability of the internal structure of the hinge mechanism.

[0022] In some possible implementations, when the locking member is in the locked state, the central axis of the limiting hole coincides with the central axis of the locking hole; when the locking member is in the unlocked state, the central axis of the limiting hole and the central axis of the locking hole are spaced apart. By setting the central axis of the limiting hole to coincide with the central axis of the locking hole when the locking member is in the locked state, the complexity of the moving block structure can be effectively reduced, and the moving path of the moving block can be parallel to the central axis of the limiting hole, which also helps to reduce the space occupied by the moving block.

[0023] In some possible implementations, the first link includes a first plate and a second plate, one end of the first plate forms a first end, the second plate is connected to the other end of the first plate, the other end of the first plate and the second plate together form a second end, and the second rotation center of the second end is located at the other end of the first plate;

[0024] The first link also includes a guide rail, which includes a first part forming a first sliding groove and a second part forming a second sliding groove. The first part is fixed to the first plate, and the second part is fixed to the first plate and the second plate.

[0025] The second link includes a third plate and a fourth plate arranged at an angle. One end of the fourth plate forms a fourth end. The third plate is connected to the other end of the fourth plate. The other end of the fourth plate and the third plate together form a third end. The third rotation center of the third end is located at the other end of the fourth plate.

[0026] When the slider is in the third position, the second plate and the third plate are at least partially facing each other, and the locking member is located between the second plate and the third plate.

[0027] By setting the second plate and the third plate to be at least partially opposite each other, it is beneficial to ensure the locking effect of the locking element. Furthermore, the locking element being located between the second plate and the third plate also helps to make full use of the space between the second plate and the third plate, thereby improving the compactness of the hinge mechanism structure.

[0028] In some possible implementations, the locking element is positioned corresponding to the second position. When the slider is in the second position, the locking element is in a locked state; when the slider leaves the second position, the locking element is in an unlocked state. By setting the locking element to correspond to the second position, the hinge mechanism switches between the locked and unlocked states as the slider's position changes, making the locking and unlocking process of the hinge mechanism simple to implement and easy to control.

[0029] In some possible implementations, the hinge mechanism includes a first fixing member for fixing a first structural component of the vehicle, and a first end rotatably connected to the first fixing member. In other words, the first end can be fixed to the first structural component by the first fixing member, which helps to reduce the compatibility requirements between the first end and the first structural component inside the vehicle, making the hinge mechanism easy to install in different vehicles and expanding the application scenarios of the hinge mechanism.

[0030] In some possible implementations, the hinge mechanism includes a second fixing member for securing a first structural member of the vehicle. A fourth end rests on the second fixing member, and when the sixth end receives a first force, the fourth end moves away from the second fixing member. When the hinge mechanism is in the retracted state, the fourth end rests on the second fixing member. By providing the second fixing member, the fourth end can prevent further movement of the fourth end towards the first end; that is, the second fixing member can act as a positioning element, ensuring the stability of the relative positions of the drive rod, the first link, and the second link during repeated hinge mechanism movements.

[0031] In some possible implementations, the hinge mechanism includes a connecting plate for fixing the second structural member of the vehicle, and a fourth end is rotatably connected to the connecting plate. In other words, the fourth end can be rotatably connected to the second structural member via the connecting plate. By setting the connecting plate, the difficulty of adapting the fourth end to the second structural member of the cover can be reduced, making the hinge mechanism easy to install in different vehicles and expanding the application environment of the hinge mechanism.

[0032] Secondly, this application also provides a spring-loaded device. The spring-loaded device includes a drive member and a hinge mechanism of any of the above possible implementations, wherein the drive member is used to output a first force and / or a second force to the sixth end.

[0033] In some possible implementations, the lifting device includes a torsion spring, which is elastically connected to the drive member and the drive rod. By incorporating the torsion spring, it can also undergo elastic deformation when the drive rod rotates, providing additional torque to the drive rod. This ensures that the torque provided by the drive mechanism is sufficient to meet the practical requirement of lifting the raised end of the cover by 100mm within 540ms.

[0034] Thirdly, this application also provides a means of transportation. The means of transportation includes a frame, a cover, and a spring-loaded device as described in any of the above possible implementations. The frame includes a first structural member, and the cover includes a second structural member. As the drive rod rotates in a first rotation direction, the distance between the raised end of the cover and the frame increases.

[0035] Understandably, when a pedestrian collides with a vehicle, the pedestrian is more likely to fall towards the raised end, making it easier for their head to hit the enclosure, or even collide with harder components like the engine housed underneath, resulting in more severe head injuries. By incorporating a spring-loaded device that moves the raised end of the enclosure relative to the frame, increasing the distance between the raised end and the frame, the cushioning space between the pedestrian's head and the frame when they are hit and fall can be effectively increased, reducing the impact on the pedestrian's head and preventing secondary collisions between the pedestrian's head and structural components inside the frame.

[0036] In some possible implementations, the vehicle includes a latch fixed to the locking end of the cover, spaced apart from the lifting end. The latch is used to lock the locking end of the cover to the frame. By using the latch, a detachable connection between the locking end of the cover and the frame is achieved. During normal use of the vehicle, the latch locks the locking end of the cover to the frame, ensuring good sealing of the space between the cover and the frame and preventing the cover from obstructing the user's view during normal use. When it is necessary to inspect or replace structural components placed between the cover and the frame, the latch can be manually unlocked to release the locking end and the frame, facilitating the user's inspection of the structural components.

[0037] In some possible implementations, the vehicle includes a controller mounted within the frame. A drive unit is electrically connected to the controller, which responds to a retraction signal and controls the drive unit to output a second force. By setting the controller to control the output of the drive unit, the coordination of the structural components within the vehicle can be improved. Furthermore, when the drive unit outputs the second force, the sixth end of the hinge mechanism is subjected to the second force, causing the hinge mechanism to retract automatically. This eliminates the need for the user to manually press the cover to reset it, resulting in a higher degree of automation for the vehicle and lower difficulty in resetting the cover.

[0038] In some possible implementations, the vehicle includes a central control screen, which is electrically connected to a controller. The central control screen responds to input operations and sends a response signal to the controller. By setting up a central control screen, the user's instructions can be transmitted to the controller, realizing information interaction between people and the vehicle.

[0039] In one possible implementation, the vehicle includes a radar electrically connected to a controller. The controller controls the drive component to output a first force when the information transmitted by the radar meets the lifting conditions. By incorporating the radar, the controller promptly controls the drive component to output the first force when it determines that the lifting conditions are met (e.g., when a pedestrian is too close to the vehicle and a collision is unavoidable). This causes the sixth end of the hinge mechanism to be subjected to the first force, thereby popping the hinge mechanism out. This results in a high degree of coordination among the internal structural components of the vehicle, a high degree of automation, and the popping device does not depend on user judgment; it can automatically pop out after the conditions are met, demonstrating high reliability.

[0063] It is understood that the specific embodiments described herein are merely illustrative of related embodiments and not intended to limit the scope of the embodiments. Furthermore, it should be noted that, for ease of description, the accompanying drawings only show the parts relevant to the embodiments. It should be understood that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0064] Please refer to the following: Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a vehicle 1000 provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the structure of the cover 200 in the first open position. Figure 3 yes Figure 1 The diagram shows the structure of the cover 200 in the second open position.

[0065] In some embodiments, the vehicle 1000 can be, for example, a vehicle or other related products capable of providing transportation services. A vehicle is a wheeled vehicle 1000 that travels on roads for passenger transport, goods transport, or special operations; vehicles may include, but are not limited to, automobiles or tractors. This application describes the vehicle 1000 as an automobile as an example; however, other types of vehicles 1000 can also adopt similar structures, which will not be elaborated upon further below.

[0066] Understandably, for ease of description, definitions will be used later in the text. Figure 1 The vehicle 1000 shown has a first direction X, a second direction Y, and a third direction Z, all of which are mutually perpendicular. The length direction of the vehicle 1000 can be parallel to the first direction X, the width direction of the vehicle 1000 can be parallel to the second direction Y, and the height direction of the vehicle 1000 can be parallel to the third direction Z. In other embodiments, the coordinate system of the vehicle 1000 can be flexibly set according to specific actual needs.

[0067] In some embodiments, the vehicle 1000 may include a frame 100 and a cover 200, with the cover 200 mounted on the frame 100. The frame 100 may be made of high-strength steel or aluminum alloy, etc., to provide strength support for the vehicle 1000 and to serve as a carrier for supporting, fixing, or connecting other structural components of the vehicle 1000, such as the cover 200, the controller 600, etc.

[0068] For example, the vehicle 1000 may have a compartment 11, and a cover 200 may be fitted over the opening of the compartment 11 and movably connected to the compartment 11. The compartment 11 may be formed by a portion of a frame 100, and the compartment 11 may be used to house other structural components within the vehicle 1000, such as an engine. The cover 200 fits over the opening of the compartment 11 to prevent external impurities such as water or dust from entering the compartment 11 and affecting the service life of the structural components housed within it.

[0069] For example, the cover 200 may include a locking end 21 and a lifting end 22 spaced apart along a first direction X. The vehicle 1000 may include a latch 23, which is fixed to the locking end 21 of the cover 200 and is used to lock the locking end 21 of the cover 200 to the frame 100. It is understood that by providing the latch 23, a detachable connection between the locking end 21 of the cover 200 and the frame 100 is achieved. For example, during normal use of the vehicle 1000 (such as... Figure 1(As shown in the diagram), the latch 23 can lock the locking end 21 of the cover 200 to the frame 100. Both the locking end 21 and the lifting end 22 of the cover 200 are in contact with the frame 100. It can also be considered that the cover 200 covers the frame 100, which can ensure that the accommodating compartment 11 has good sealing performance. In the following text, the position of the cover 200 at this time will be referred to as the initial position of the cover 200. Figure 2 As shown, when it is necessary to perform maintenance or replacement of the structural components inside the housing 11, the locking end 21 and the frame 100 can be unlocked by manually unlocking the latch 23. The lifting end 22 of the cover 200 is still in contact with the frame 100. The locking end 21 of the cover 200 can be manually lifted by the user and rotated around the lifting end 22 until it is spaced apart from the frame 100 in the third direction Z, so as to facilitate the user's maintenance process of the structural components inside the housing 11. In the following text, the position of the cover 200 at this time is referred to as the first open position of the cover 200.

[0070] In some embodiments, the vehicle 1000 may further include a pop-up device 300, which is installed between the cover 200 and the frame 100. The pop-up device 300 is used to move the cover 200 relative to the frame 100. For example, the pop-up device 300 may be positioned closer to the raised end 22 of the cover 200 than the locking end 21. It is understood that when a pedestrian collides with the vehicle 1000, the pedestrian is generally closer to the locking end 21 of the cover 200, and is more likely to fall from the locking end 21 towards the raised end 22, making it easier for the pedestrian's head to hit the cover 200, or even collide with harder components such as the engine inside the compartment 11 under the cover 200, resulting in more severe head injuries. By providing the pop-up device 300, and positioning it close to the raised end 22, the pop-up device 300 can move the cover 200 relative to the frame 100 to a second open position (e.g., Figure 3 As shown), at this time, the distance between the raised end 22 of the cover 200 and the frame 100 increases, which can effectively increase the buffer space between the pedestrian's head and the housing 11 when the pedestrian is hit and falls, so as to reduce the injury to the pedestrian's head and also avoid secondary collisions between the pedestrian's head and the structural components inside the housing 11. The pop-up device 300 can have an extended state and a retracted state, such as... Figure 1 and Figure 2 As shown, the pop-up device 300 is in the retracted state, and the cover 200 is in the initial position or the first open position. At this time, the lifting end 22 of the cover 200 is connected to the frame 100, and the distance between the lifting end 22 of the cover 200 and the frame 100 in the third direction Z is less than or equal to the distance between the locking end 21 of the cover 200 and the frame 100 in the third direction Z. Figure 3As shown, when the pop-up device 300 is in the pop-up state, the cover 200 is in the second open position. The distance between the raised end 22 of the cover 200 and the frame 100 in the third direction Z is greater than the distance between the locking end 21 of the cover 200 and the frame 100 in the third direction Z.

[0071] For example, the frame 100 may include a first structural member 12, the cover 200 may include a second structural member 24, and a pop-up device 300 may be connected between the first structural member 12 and the second structural member 24 to drive the second structural member 24 to move relative to the first structural member 12. The locking ends 21 of the first structural member 12 and the second structural member 24 relative to the cover 200 may both be closer to the lifting end 22. By switching between the pop-up state and the retracted state of the pop-up device 300, the first structural member 12 is moved closer to or further away from the second structural member 24, thereby realizing the opening and closing process of the lifting end 22 of the cover 200 relative to the frame 100. During the switching process between the retracted and extended states of the pop-up device 300, the latch 23 still locks the locking end 21 of the cover 200 and the frame 100. The second structural member 24 (i.e., the raised end 22 of the cover 200) rotates relative to the first structural member 12 (i.e., the frame 100) with the latch 23 as the pivot point, driven by the pop-up device 300, moving closer to or away from the first structural member 12.

[0072] In some embodiments, the vehicle 1000 may include a cabin 13, which is enclosed by another portion of the frame 100. The cabin 13 can provide space for users to sit and operate, thereby realizing the carrying function of the vehicle 1000. For example, the accommodating compartment 11 and the cabin 13 can be arranged along a first direction X, and the cabin 13 can be located on the side of the raised end 22 of the cover 200 opposite to the locking end 21 of the cover 200. When a pedestrian collides with the vehicle 1000, by setting a pop-up device 300 to increase the distance between the raised end 22 and the frame 100, the pedestrian can be prevented from being knocked into the cabin 13, thus avoiding greater losses to the user due to the collision.

[0073] In some embodiments, the vehicle 1000 may include a central control screen 400, which may be fixedly connected to the frame 100 and located within the cabin 13. It is understood that the central control screen 400's fixed connection to the frame 100 can be either contacting and connected to the frame 100, or connected to the frame 100 via other structural components of the vehicle 1000; this application embodiment does not limit this. For example, the central control screen 400 may integrate display and touch sensing functions. The display function of the central control screen 400 can be used to display text, images, videos, etc., and the touch sensing function can be used to detect user touch actions to achieve information interaction between the user and the vehicle 1000. The central control screen 400 may be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display, etc.; this application embodiment does not limit this. In some other embodiments, the central control screen 400 may not include touch sensing functionality, and this application embodiment does not limit this.

[0074] In some embodiments, the vehicle 1000 may include a radar 500, which may be fixedly connected to the frame 100. For example, the radar 500 may be a lidar 500, and the specific type of radar 500 is not limited in this application embodiment. The radar 500 can be used to detect the size of objects around the vehicle 1000, such as other vehicles, pedestrians, buildings, etc., and their distance from the vehicle 1000.

[0075] In some embodiments, the vehicle 1000 may include a controller 600, which may be fixedly connected to the frame 100. The controller 600 may be a central processing unit, or other general-purpose processors, digital signal processors, etc. The controller 600 is the control center of the vehicle 1000, connecting various parts of the vehicle 1000 through various interfaces and lines to coordinate the coordinated operation of the components within the vehicle 1000.

[0076] For example, the controller 600 can be electrically connected to the pop-up device 300. The controller 600 can control the switching of the pop-up device 300 between the pop-up state and the retracted state, which helps to reduce the difficulty of using the pop-up device 300 and makes the operation of the internal components of the vehicle 1000 highly automated. Specifically, the controller 600 can be used to respond to a pop-up signal to control the pop-up device 300 to pop up from the retracted state to the pop-up state; and / or, the controller 600 can also be used to respond to a retraction signal to control the pop-up device 300 to retract from the pop-up state to the retracted state.

[0077] The radar 500 can be electrically connected to the controller 600. The radar 500 can transmit the detected information to the controller 600 to provide the controller 600 with a basis for judgment. The controller 600 can make judgments based on the detected information and make corresponding responses. Specifically, when the controller 600 determines that the information transmitted by the radar 500 meets the lifting conditions, for example, when the radar 500 detects that the distance between the vehicle 1000 and the pedestrian is too small and a collision is unavoidable, the information transmitted by the radar 500 can be regarded as a pop-up signal by the controller 600. The controller 600 can respond to the pop-up signal and control the pop-up device 300 to pop up from the retracted state to the pop-up state, so as to increase the distance between the raised end 22 of the cover 200 and the frame 100, increase the buffer space between the cover 200 and the housing 11, and effectively reduce the injury to the pedestrian in the event of a collision. At this time, the cover 200 moves from the initial position to the second open position.

[0078] The central control screen 400 can be electrically connected to the controller 600. The central control screen 400 can respond to user input operations and send a retraction signal to the controller 600. After a collision occurs, the controller 600 can respond to the retraction signal and control the pop-up device 300 to retract from the popped-out state to the retracted state. That is, the pop-up device 300 drives the raised end 22 of the cover 200 to move towards the frame 100 until it contacts the frame 100. The cover 200 then returns from the second open position to the initial position to prepare for the next possible collision. The retraction process of the pop-up device 300 is simple and highly automated, avoiding the process of the user manually pushing the cover 200 back to the initial position. This helps reduce the difficulty of resetting the pop-up device 300 and increases the possibility of reusing the pop-up device 300. It is understood that users can send a retraction signal to the controller 600 through the touch sensing function of the central control screen 400. In some other embodiments, the vehicle 1000 may also include a voice assistant, and users can send a retraction signal to the controller 600 through voice input and other means to control the retraction process of the pop-up device 300. This application embodiment does not limit this.

[0079] Among them, Figure 1 In the vehicle 1000 shown, there can be two pop-up devices 300. Both pop-up devices 300 are located on the same side of the latch 23 and are spaced apart along the second direction Y. It is understood that the number of pop-up devices 300 in the vehicle 1000 can be less or more, and the structure of each pop-up device 300 can be the same or have slight differences. This application does not make strict limitations on this.

[0080] Understandable, Figure 1 , Figure 2 and Figure 3The diagram only schematically illustrates some of the components included in the vehicle 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 , Figure 2 and / or Figure 3 Restrictions.

[0081] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 2 The diagram shows a partial structural representation of the vehicle 1000 in some embodiments. Figure 5 yes Figure 3 The diagram shows the structure of the vehicle 1000 in some embodiments. Figure 4 The spring-loaded device 300 shown is in the retracted state. Figure 5 The pop-up device 300 shown is in the pop-up state.

[0082] In some embodiments, the pop-up device 300 may include a hinge mechanism 31 and a drive mechanism 32. The hinge mechanism 31 may have an extended state and a retracted state, and the drive mechanism 32 may be used to drive the hinge mechanism 31 to switch between the retracted state and the extended state, thereby realizing the switching of the pop-up device 300 between the retracted state and the extended state. The hinge mechanism 31 may be connected to the first structural member 12 (e.g., Figure 2 The drive mechanism 32 can be electrically connected to the controller 600 (as shown) between the second structural member 24 and the second structural member 24. Figure 1 As shown, the controller 600 can control the different forces provided by the drive mechanism 32 to the hinge mechanism 31, thereby driving the second structural member 24 (i.e., near the raised end 22 of the cover 200) to move closer to or further away from the first structural member 12.

[0083] When the pop-up device 300 is installed inside the vehicle 1000, the length direction of the pop-up device 300 can be parallel to the first direction X, the width direction of the pop-up device 300 can be parallel to the second direction Y, and the height direction of the pop-up device 300 can be parallel to the third direction Z. In some other embodiments, when the pop-up device 300 is installed inside the vehicle 1000, the length direction of the pop-up device 300 can also be set at an angle to the first direction X, and / or the width direction of the pop-up device 300 can also be set at an angle to the second direction Y, and / or the height direction of the pop-up device 300 can also be set at an angle to the third direction Z. This application embodiment does not limit this.

[0084] Please refer to the combination Figures 6 to 8B , Figure 6 yes Figure 4 The diagram shows the structure of the spring-loaded device 300. Figure 7 yes Figure 6The diagram shows a partial exploded view of the hinge mechanism 31. Figure 8A yes Figure 6 The diagram shows the structure of the first link 311. Figure 8B yes Figure 6 The first link 311 shown is a structural schematic diagram from another perspective.

[0085] In some embodiments, the hinge mechanism 31 may include a first link 311, which may be a generally "L"-shaped plate structure. The first link 311 may include a first plate 3111 and a second plate 3112, and the first plate 3111 and the second plate 3112 may be arranged at an included angle. The dimension of the first plate 3111 in its extending direction may be larger than the dimension of the second plate 3112 in its extending direction. The boundary line between the first plate 3111 and the second plate 3112 can be referenced. Figure 8A The dashed lines in the diagram are for illustrative purposes only. The actual shape, size, position, and structure of the first link 311 are not affected by these lines. Figures 6 to 8B The boundary line may be located in other positions in some other embodiments, and this application does not impose any restrictions.

[0086] For example, the first link 311 may include a first end 311a and a second end 311b. One end of the first plate 3111 (denoted as the first end 3111a of the first plate 3111) may form the first end 311a, and the second plate 3112 may be connected to the other end of the first plate 3111 (denoted as the second end 3111b of the first plate 3111). The other end of the first plate 3111 (i.e., the second end 3111b) and the second plate 3112 together form the second end 311b. It is understood that the first plate 3111 and the second plate 3112 are arranged at an angle, that is, the extending direction of the second plate 3112 intersects the arrangement direction of the first end 3111a and the second end 3111b. In some other embodiments, the first link 311 may not include the second plate 3112, the second end 311b may be formed by the second end 3111b of the first plate 3111, and the first link 311 may be straight or other shapes. This application does not limit this.

[0087] For example, the first plate 3111 may be provided with a first shaft hole 31111. The first plate 3111 has a first surface 31112 and a second surface 31113 disposed opposite each other in the second direction Y. The first shaft hole 31111 passes through the first surface 31112 and the second surface 31113, and the first shaft hole 31111 is located in the first end 3111a. The first shaft hole 31111 can be used to allow other structural components to be inserted into or pass through the first end 3111a of the first plate 3111, that is, the first end 311a of the first connecting rod 311, so as to realize the connection between the first end 311a of the first connecting rod 311 and other structural components. In some other embodiments, the first plate 3111 may not include the first shaft hole 31111, but includes a first boss. The first boss can be inserted into or pass through other structural components to realize the connection between the first end 311a of the first connecting rod 311 and other structural components. This application embodiment does not limit this.

[0088] For example, the first plate 3111 may be provided with a second shaft hole 31114, which can penetrate the first surface 31112 and the second surface 31113 and is located within the second end 3111b. The second shaft hole 31114 can be used to allow other structural components to be inserted into or pass through the second end 3111b of the first plate 3111, that is, the second end 311b of the first connecting rod 311, so as to connect the second end 311b of the first connecting rod 311 to other structural components. In some other embodiments, the first plate 3111 may not include the second shaft hole 31114, but may include a second boss, which can be inserted into or pass through other structural components to connect the second end 311b of the first connecting rod 311 to other structural components. This application embodiment does not limit this. It is understandable that the second shaft hole 31114 is located at the second end 3111b of the first plate 3111, and the first shaft hole 31111 is located at the first end 3111a of the first plate 3111. In other words, the first shaft hole 31111 and the second shaft hole 31114 are located at opposite ends of the first plate 3111.

[0089] For example, the first plate 3111 may include a first plate portion 31115, a connecting portion 31116, and a second plate portion 31117. The connecting portion 31116 is connected between the first plate portion 31115 and the second plate portion 31117, and the first plate portion 31115 is recessed relative to the second plate portion 31117 toward the side where the second surface 31113 is located. A first end 3111a is formed at the end of the first plate portion 31115, and a second end 3111b is formed at the end of the second plate portion 31117. In other words, a portion of the first plate 3111 (i.e., the connecting portion 31116) can be bent to connect the first end 3111a and the second end 3111b. In other words, the first shaft hole 31111 is provided in the first plate portion 31115, and the second shaft hole 31114 is provided in the second plate portion 31117. The first shaft hole 31111 and the second shaft hole 31114 are offset in the second direction Y. In some other embodiments, the first plate body 3111 may not include the connecting portion 31116, and the first end 3111a and the second end 3111b may be connected in a straight line.

[0090] For example, the first connecting rod 311 may further include a guide rail 3113, which may include a first portion 31131 and a second portion 31132. The first portion 31131 is fixed to the first plate 3111, and the second portion 31132 is fixed to the first plate 3111 and the second plate 3112. In some examples, the guide rail 3113 is disposed on the first surface 31112, and the first portion 31131 is fixed to the second plate portion 31117, located on the side of the second shaft hole 31114 facing the first shaft hole 31111, and the second portion 31132 is fixed to the second plate portion 31117 and the second plate 3112. In other embodiments, the guide rail 3113 may also be disposed at other positions of the first connecting rod 311, which is not limited in this application.

[0091] For example, the first link 311 may have a first sliding groove 31133, which is formed within the first portion 31131 of the guide rail 3113. In some examples, the first sliding groove 31133 may include a first position 3113a and a second position 3113b, which may be located at opposite ends of the first sliding groove 31133, with the first position 3113a located on the side of the second position 3113b closer to the first end 311a. The first sliding groove 31133 serves as a guide, allowing structural members mounted within it to move between the first position 3113a and the second position 3113b along the extending direction of the first sliding groove 31133.

[0092] In some examples, the first sliding groove 31133 can be a straight groove, and the extending direction of the first sliding groove 31133 is parallel to the line connecting the center of the first shaft hole 31111 and the center of the second shaft hole 31114. It is understood that, in this embodiment, due to the bending arrangement of the first plate portion 31115 and the second plate portion 31117, the line connecting the center of the first shaft hole 31111 and the center of the second shaft hole 31114 is staggered in the second direction Y. The line connecting the center of the first shaft hole 31111 and the center of the second shaft hole 31114 should be understood as the arrangement direction of the centers of the first shaft hole 31111 and the second shaft hole 31114 along the extending direction of the first connecting rod 311. In other embodiments, the extending direction of the first sliding groove 31133 may also intersect the line connecting the center of the first shaft hole 31111 and the center of the second shaft hole 31114, or the first sliding groove 31133 may be a curved groove or other shapes; this embodiment does not limit this.

[0093] For example, the first connecting rod 311 may have a second sliding groove 31134, which is located at the second end 311b and communicates with the first sliding groove 31133. The second sliding groove 31134 has a third position 3113c, which is located on the side of the second position 3113b away from the first position 3113a. It can be understood that the second sliding groove 31134 can be considered to be formed in the second part 31132 of the guide rail 3113, that is, the second sliding groove 31134 extends from the second plate portion 31117 to the second plate body 3112. Since the second plate body 3112 is set at an angle to the first plate body 3111, in other words, the first position 3113a and the second position 3113b are collinear, and the third position 3113c is bent relative to the second position 3113b.

[0094] In some examples, the second sliding groove 31134 can be an arc groove. It is understood that the second position 3113b can also be considered to be located at the junction of the second sliding groove 31134 and the first sliding groove 31133. That is, the second position 3113b and the third position 3113c can be considered to be the two opposite ends of the arc groove. The structural component installed in the second sliding groove 31134 can move between the second position 3113b and the third position 3113c along the extension direction of the second sliding groove 31134.

[0095] For example, the second end 311b may be provided with a limiting hole 31121, which can pass through the opposite sides of the first connecting rod 311 and connect to the third position 3113c of the second sliding groove 31134. In some other embodiments, the limiting hole 31121 may also be provided in other positions, which is not limited in this application embodiment.

[0096] In some examples, the second end 311b may be provided with a limiting groove 31122. The limiting groove 31122 can be considered to be formed by a portion of the second plate 3112 recessed towards the side where the first surface 31112 is located. The limiting groove 31122 can communicate with the limiting hole 31121. The central axis of the limiting groove 31122 may coincide with the central axis of the limiting hole 31121. The limiting groove 31122 can be used to install and accommodate other structural components, which helps to improve the space utilization of the first connecting rod 311.

[0097] Please refer to the following: Figure 6 , Figure 7 and Figure 9 , Figure 9 yes Figure 6 The second link 312 shown is a structural schematic diagram from another perspective.

[0098] In some embodiments, the hinge mechanism 31 may include a second link 312, which may be a plate structure. The second link 312 may include a third plate 3121 and a fourth plate 3122, and the fourth plate 3122 and the third plate 3121 may be arranged at an angle. The angle between the extending direction of the third plate 3121 and the extending direction of the fourth plate 3122 may be an obtuse angle, and the dimension of the fourth plate 3122 in its extending direction may be larger than the dimension of the third plate 3121 in its extending direction. The boundary line between the third plate 3121 and the fourth plate 3122 can be referenced. Figure 9 The dashed lines in the diagram are for illustrative purposes only; the actual shape, size, position, and structure of the second link 312 are not affected. Figure 6 , Figure 7 and / or Figure 9 The boundary line may be located in other positions in some other embodiments, and this application does not impose any restrictions.

[0099] For example, the second link 312 may include a third end 312a and a fourth end 312b. One end of the fourth plate 3122 (denoted as the fourth end 3122b of the fourth plate 3122) may form the fourth end 312b. The third plate 3121 may be connected to the other end of the fourth plate 3122 (denoted as the third end 3122a of the fourth plate 3122). The other end of the fourth plate 3122 (i.e., the third end 3122a) and the third plate 3121 together form the third end 312a. It is understood that the fourth plate 3122 and the third plate 3121 are arranged at an angle, that is, the extending direction of the third plate 3121 intersects with the arrangement direction of the third end 3122a and the fourth end 3122b. In some other embodiments, the second link 312 may not include the third plate 3121, the third end 312a may be formed by the third end 3122a of the fourth plate 3122, and the second link 312 may be straight or other shapes. This application does not limit this.

[0100] For example, the fourth plate 3122 may be provided with a third shaft hole 31221. The fourth plate 3122 has a third surface 31222 and a fourth surface 31223 disposed opposite to each other in the second direction Y. The third shaft hole 31221 penetrates the third surface 31222 and the fourth surface 31223, and the third shaft hole 31221 is located in the third end 3122a. The third shaft hole 31221 can be used to allow other structural members to be inserted into or pass through the third end 3122a of the fourth plate 3122, that is, the third end 312a of the second connecting rod 312, so as to realize the connection between the third end 312a of the second connecting rod 312 and other structural members. In some other embodiments, the fourth plate 3122 may not include the third shaft hole 31221, but includes a third boss. The third boss can be inserted into or pass through other structural members to realize the connection between the third end 312a of the second connecting rod 312 and other structural members. This application embodiment does not limit this.

[0101] For example, the fourth plate 3122 may be provided with a fourth shaft hole 31224, which can penetrate the third surface 31222 and the fourth surface 31223 and is located within the fourth end 3122b. The fourth shaft hole 31224 can be used to allow other structural components to be inserted into or pass through the fourth end 3122b of the fourth plate 3122, that is, the fourth end 312b of the second connecting rod 312, thereby connecting the fourth end 312b of the second connecting rod 312 with other structural components. In some other embodiments, the fourth plate 3122 may not include the fourth shaft hole 31224, but may include a fourth boss, which can be inserted into or pass through other structural components to connect the fourth end 312b of the second connecting rod 312 with other structural components. This application embodiment does not limit this. It is understandable that the third shaft hole 31221 is located at the third end 3122a of the fourth plate 3122, and the fourth shaft hole 31224 is located at the fourth end 3122b of the fourth plate 3122. In other words, the third shaft hole 31221 and the fourth shaft hole 31224 are located at opposite ends of the fourth plate 3122.

[0102] For example, the third end 312a may also include a locking hole 31211, which may extend through the opposite sides of the second link 312, and the locking hole 31211 is located on the side of the third shaft hole 31221 away from the fourth shaft hole 31224.

[0103] For example, the second link 312 may include a third plate portion 312c, a fourth plate portion 312d, and a fifth plate portion 312e connected in sequence, with the fourth plate portion 312d protruding relative to the third plate portion 312c and the fifth plate portion 312e toward the side where the third surface 31222 is located. The fourth shaft hole 31224 is located within the fifth plate portion 312e, the third shaft hole 31221 is located within the fourth plate portion 312d, and the locking hole 31211 is located within the third plate portion 312c. In other words, a portion of the second link 312 (i.e., the fourth plate portion 312d) may be bent, and the third shaft hole 31221, the fourth shaft hole 31224, and / or the locking hole 31211 may be offset in the second direction Y. In some other embodiments, the second link 312 may also be straight.

[0104] Please refer to the following: Figure 7 and Figure 10 , Figure 10 yes Figure 6 The diagram shows the structure of the drive rod 313 from another perspective.

[0105] In some embodiments, the hinge mechanism 31 may include a drive rod 313, which may be approximately a straight plate structure. For example, the drive rod 313 may include a fifth end 313a and a sixth end 313b, which may be opposite ends of the drive rod 313 in the extending direction of the drive rod 313.

[0106] In some examples, the fifth end 313a may be provided with a slider 3131, which can be used to install in other structural components to realize the connection between the drive rod 313 and other structural components.

[0107] In some examples, the sixth end 313b may be provided with a fifth shaft hole 3132, which can penetrate the driving rod 313 on opposite sides in the second direction Y. The fifth shaft hole 3132 can be used to allow other structural components to be inserted into or pass through the driving rod 313, thereby connecting the driving rod 313 with other structural components. In other embodiments, the driving rod 313 may not include the fifth shaft hole 3132, but may include a fifth boss, which can be inserted into or pass through other structural components to connect the sixth end 313b of the driving rod 313 with other structural components. This application does not limit this aspect.

[0108] For example, the hinge mechanism 31 may also include a pivot (not shown in the figure), which can be used to insert different structural components within the hinge mechanism 31 so that the hinge mechanism 31 can form a modular structure.

[0109] Please refer to the following: Figure 7 , Figures 10 to 12 , Figure 11 yes Figure 6 A schematic diagram showing the movement of slider 3131 within the hinge mechanism 31 in the second sliding groove 31134. Figure 12 yes Figure 6 This diagram illustrates the movement of slider 3131 within the hinge mechanism 31, specifically within the first sliding groove 31133. Figure 11 The slider 3131, indicated by the dashed line, is located in the third position 3113c. Figure 11 and Figure 12 The slider 3131, indicated by a solid line, is located at the second position 3113b. Figure 12 The slider 3131, indicated by the dashed line, is located at the first position 3113a. For details regarding the structure of the first connecting rod 311, please refer to [link to relevant documentation]. Figure 7 , Figure 8A and Figure 8B For detailed structural information on the second link 312, please refer to [link / reference needed]. Figure 7 and Figure 9 For details on the mechanism of drive lever 313, please refer to [link / reference]. Figure 7 and Figure 10 .

[0110] In some embodiments, the first link 311 may be driveably connected between the drive rod 313 and the second link 312. For example, the third end 312a may be rotatably connected to the second end 311b, the fourth end 312b is located on the side of the third end 312a near the first end 311a, the fifth end 313a is driveably connected to the first link 311, and the sixth end 313b is located on the side of the fifth end 313a near the first end 311a, and on the side of the first link 311 facing away from the second link 312. It is understood that in the relevant description herein, drive connections can be understood as two or more components being connected together by some assembly method to achieve force transmission.

[0111] The rotating shaft can pass through the second shaft hole 31114 and the third shaft hole 31221 (e.g. Figure 7 As shown, the third end 312a can be rotatably connected to the second end 311b via a rotating shaft, which helps improve the reliability of the rotation of the third end 312a relative to the second end 311b, as well as the stability of the connection between the second end 311b and the third end 312a. Both the second end 311b and the third end 312a rotate relative to each other about the central axis of the rotating shaft. In other words, the center of the second shaft hole 31114 is the second rotation center of the second end 311b, and the center of the third shaft hole 31221 is the third rotation center of the third end 312a. Both the third rotation center and the second rotation center are located on the central axis of the rotating shaft and are coaxially arranged.

[0112] During the rotation of the drive rod 313 around the sixth end 313b, the rotation center of the drive rod 313 is the center of the fifth shaft hole 3132, and the slider 3131 (as shown) Figure 10 The motion path shown should also be an arc centered on the center of the fifth shaft hole 3132. Therefore, when the slider 3131 is installed in the first sliding groove 31133, as shown... Figure 12 As shown, when the slider 3131 moves between the first position 3113a and the second position 3113b along the extension direction of the first sliding groove 31133, the linear movement of the slider 3131 along the first sliding groove 31133 will push the first sliding groove 31133, i.e. the first connecting rod 311, to rotate, thereby driving the second connecting rod 312, which is rotatably connected to the first connecting rod 311, to move. Since the first connecting rod 311 rotates with the first shaft hole 31111 of the first end 311a as the first rotation center, the second end 311b also rotates with the first end 311a as the rotation center, thereby driving the third end 312a to be subjected to force and move, thus realizing the transmission connection between the drive rod 313, the first connecting rod 311, and the second connecting rod 312.

[0113] In addition, such as Figure 11 As shown, when the slider 3131 is installed in the second sliding groove 31134, the slider 3131 is at the second position 3113b (combined with) along the extending direction (arc groove) of the second sliding groove 31134. Figure 11 (as shown) and the third position 3113c (in combination) Figure 11 As shown, the slider 3131 moves between the two positions. The arc motion of the slider 3131 within the second sliding groove 31134 also revolves around the sixth end 313b. Therefore, the movement of the slider 3131 within the second sliding groove 31134 does not generate additional torque on the first connecting rod 311. At this time, the first connecting rod 311 and the second connecting rod 312 remain relatively stationary. In this embodiment, the hinge mechanism 31 is considered to be in a retracted state whenever the slider 3131 is located at any position between the second position 3113b and the third position 3113c. When the slider 3131 is located at the first position 3113a, the hinge mechanism 31 is in an extended state.

[0114] By mounting the slider 3131 onto the first sliding groove 31133 and defining the groove shape of the first sliding groove 31133, the slider 3131 can drive the first connecting rod 311 to move together with it when it moves within the first sliding groove 31133. The transmission structure between the drive rod 313 and the first connecting rod 311 is simple and has fewer parts, which helps to reduce the structural complexity and manufacturing cost of the hinge mechanism 31. In some other embodiments, the fifth end 313a can also be connected to the first connecting rod 311 in other ways, which is not limited in this application. In this application embodiment, the first sliding groove 31133 is a straight groove to ensure that the slider 3131 can drive the first connecting rod 311 to move when it moves within the first sliding groove 31133. In some other embodiments, the first sliding groove 31133 can also be a curved groove or other shapes, as long as it can drive the first connecting rod 311 to move during the movement of the slider 3131, which is not limited in this application.

[0115] Furthermore, in this embodiment, by setting the sixth end 313b to be located on the side of the fifth end 313a close to the first end 311a, it is beneficial for the drive rod 313 to match the motion and space requirements of the hinge mechanism 31. Understandably, for example, during the movement of slider 3131 within the first sliding groove 31133, by setting the sixth end 313b to be located near the first end 311a of the fifth end 313a, the direction of the force exerted by slider 3131 on the first connecting rod 311 is set at an angle to the extension direction of the first connecting rod 311. In other words, the driving rod 313 pushes the first connecting rod 311 to rotate at an angle, which helps to convert more of the rotational motion of the driving rod 313 into linear motion of slider 3131 within the first sliding groove 31133. This effectively reduces the transmission loss between the driving rod 313 and the first connecting rod 311, allowing the first connecting rod 311 to rotate at a larger angle with a smaller torque. This improves the smoothness and fluidity of the rotation of the first connecting rod 311, ensuring the smoothness of the hinge mechanism 31 switching between the pop-out and retracted states.

[0116] Combination Figure 2 and Figure 6 As shown, when the hinge mechanism 31 is installed in the pop-up device 300 and in the vehicle 1000, the first end 311a can be rotatably connected to the first structural member 12 (i.e., the frame 100), the fourth end 312b is rotatably connected to the second structural member 24 (i.e., the raised end 22 of the cover 200), and the sixth end 313b is used for transmission connection to the drive mechanism 32. The drive mechanism 32 can output different forces to the sixth end 313b and utilize the transmission connection between the first link 311, the second link 312 and the drive rod 313 to realize different relative movements of the first link 311, the second link 312 and the drive rod 313, so as to drive the second structural member 24 to move closer to or away from the first structural member 12, thereby realizing the movement of the cover 200 between the initial position and the second open position.

[0117] In some examples, the hinge mechanism 31 may further include a first fixing member 316, which is used to fix and connect the first structural member 12 of the vehicle 1000. The first end 311a is rotatably connected to the first fixing member 316. In other words, the first end 311a can be rotatably connected to the first structural member 12 through the first fixing member 316, which helps to reduce the difficulty of adapting the first end 311a to the first structural member 12, making the hinge mechanism 31 easier to install in the vehicle 1000 and expanding the application scenarios of the hinge mechanism 31. In other embodiments, the hinge mechanism 31 may not include the first fixing member 316, and the first end 311a can contact and rotatably connect to the first structural member 12.

[0118] In some embodiments, the hinge mechanism 31 may further include a connecting plate 318, which can be used to fix and connect the second structural member 24 of the vehicle 1000, and the fourth end 312b is rotatably connected to the connecting plate 318. In other words, the fourth end 312b can be rotatably connected to the second structural member 24 through the connecting plate 318, so as to drive the second structural member 24 to move with the fourth end 312b. By providing the connecting plate 318, the difficulty of adapting the fourth end 312b to the second structural member 24 of the cover 200 can be reduced, making the hinge mechanism 31 easier to install inside the vehicle 1000, which is beneficial to expanding the application environment of the hinge mechanism 31. In some other embodiments, the fourth end 312b can contact and rotatably connect to the second structural member 24, and the hinge mechanism 31 may not include the connecting plate 318.

[0119] In some embodiments, the hinge mechanism 31 includes a second fixing member 317 for fixing the first structural member 12 of the vehicle 1000. The fourth end 312b rests on the second fixing member 317. When the sixth end 313b receives the first force F1, the fourth end 312b moves away from the second fixing member 317. In other words, when the hinge mechanism 31 is in the retracted state, the fourth end 312b rests on the second fixing member 317. The second fixing member 317 can prevent the fourth end 312b from continuing to move towards the first end 311a. In other words, the second fixing member 317 can play a positioning role, ensuring the stability and certainty of the positions of the drive rod 313, the first connecting rod 311, and the second connecting rod 312 each time the hinge mechanism 31 retracts from the pop-out state to the retracted state, thereby improving the repeatability of the hinge mechanism 31's operation.

[0120] Please refer to the following: Figure 12 and Figure 13 , Figure 13 yes Figure 12 The diagram shows a simplified representation of the mechanism of slider 3131 in the second position 3113b. Figure 13 The dashed line with an arrow indicates the direction of rotation. For ease of description, triangles with diagonal lines on the bottom indicate fixed points, solid sectors indicate rotatable parts in hinge mechanism 31, straight lines indicate parts in hinge mechanism 31 that can rotate, and circles with squares indicate parts that can move on the parts within hinge mechanism 31.

[0121] For example, the drive mechanism 32 can output a first force F1, the sixth end 313b is used to receive the first force F1, the drive rod 313 will rotate around the sixth end 313b in a first rotation direction to drive the first connecting rod 311 to rotate around the first end 311a, the second connecting rod 312 moves with the second end 311b and rotates around the second end 311b, and the fourth end 312b moves away from the first end 311a.

[0122] For example, with Figure 12 From the perspective shown, when the sixth end 313b is subjected to a first force F1 that causes the drive rod 313 to rotate counterclockwise, the slider 3131 can move from the second position 3113b toward the first position 3113a (at this time, the first rotation direction is counterclockwise) within the first sliding groove 31133. The movement of the slider 3131 can drive the first connecting rod 311 to rotate counterclockwise around the first end 311a as the first rotation center, and the third end 312a will move toward the side closer to the first end 311a under the drive of the second end 311b. And because the third end 312a is rotatably connected to the first end 311a... The second end 311b and the second link 312 will also rotate clockwise around the third end 312a as the rotation center, thereby driving the fourth end 312b of the second link 312 to move away from the first end 311a. The hinge mechanism 31 opens from the retracted state to the pop-out state, and the pop-up device 300 pops out from the retracted state to the pop-out state. Since the fourth end 312b is rotatably connected to the second structural member 24, that is, the second structural member 24 moves away from the first structural member 12 under the drive of the fourth end 312b, thereby realizing the rise of the raised end 22 of the cover 200 relative to the frame 100.

[0123] Please refer to the following: Figure 12 and Figure 14 , Figure 14 yes Figure 12 The diagram shown is a simplified representation of the mechanism of slider 3131 in the first position 3113a.

[0124] For example, the drive mechanism 32 can output a second force F2, the sixth end 313b is used to receive the second force F2, the drive rod 313 will rotate around the sixth end 313b in a second rotation direction to drive the first link 311 to rotate around the first end 311a, the second link 312 moves with the second end 311b and rotates around the second end 311b, and the fourth end 312b moves toward the first end 311a.

[0125] For example, with Figure 14From the perspective shown, when the sixth end 313b is subjected to a second force F2 that causes the drive rod 313 to rotate clockwise, the slider 3131 can move from the first position 3113a toward the second position 3113b within the first sliding groove 31133. The movement of the slider 3131 can drive the first connecting rod 311 to rotate clockwise around the first end 311a as the first rotation center. Furthermore, the third end 312a will move away from the first end 311a under the influence of the second end 311b. Since the third end 312a is also rotatably connected to the second end 311b, The second link 312 will also rotate counterclockwise around the third end 312a as the rotation center, thereby driving the fourth end 312b of the second link 312 to move towards the first end 311a. The hinge mechanism 31 retracts from the pop-out state to the retracted state, and the pop-up device 300 retracts from the pop-out state to the retracted state. Since the fourth end 312b is rotatably connected to the second structural member 24, that is, the second structural member 24 moves towards the first structural member 12 under the drive of the fourth end 312b, thereby realizing the retraction of the raised end 22 of the cover 200 relative to the frame 100.

[0126] In this embodiment, by changing the force on the drive rod 313, the hinge mechanism 31 can be switched between the pop-out state and the retracted state. The operation is simple and helps to simplify the difficulty and control cost of reusing the hinge mechanism 31.

[0127] Please refer to it again. Figure 7 and Figure 11 For example, the first link 311 can be stacked between the second link 312 and the drive link 313. In other words, the second link 312 and the drive link 313 can be located on opposite sides of the first link 311. In some other embodiments, the first link 311, the second link 312, and / or the drive link 313 can also be arranged in an overlapping manner. For example, a portion of the third end 312a and the fifth end 313a of the drive link 313 are located on the first surface 31112 of the first link 311. This embodiment of the application does not limit this. By arranging the drive link 313, the first link 311, and the second link 312 in a stacked manner, it is beneficial to improve the smoothness of the movement of the hinge mechanism 31 and avoid interference between the components within the hinge mechanism 31.

[0128] In some examples, the third surface 31222 of the second link 312 faces the second surface 31113 of the first link 311. In other words, the first plate portion 31115 (e.g.) Figure 8B (As shown) relative to the second plate portion 31117 (as shown) Figure 8B As shown) the fourth plate portion 312d is recessed towards the side of the second connecting rod 312. Figure 7 (As shown) relative to the third plate portion 312c (as shown) Figure 7(as shown) and the fifth plate 312e (as shown) Figure 7 (As shown) it protrudes towards the first link 311. By setting a portion of the first link 311 and / or a portion of the second link 312 to be bent, the motion and space requirements of the hinge mechanism 31 can be effectively matched. For example, by setting a portion of the second link 312 to be bent, the distance between the connection point of the first link 311 and the second link 312 (such as the area corresponding to the fourth plate portion 312d) can be shortened, that is, the distance between the third shaft hole 31221 and the second shaft hole 31114 can be shortened, and the length of the rotating shaft can be shortened, so as to reduce transmission loss and reduce the manufacturing cost of the hinge mechanism 31. In other positions of the second link 312 (such as the area corresponding to the third plate portion 312c and the fifth plate portion 312e), by setting a portion of the second link 312 to be bent, the distance between the first link 311 and the second link 312 can be increased, so as to reduce the friction between the first link 311 and the second link 312 and improve the smoothness of the movement of the hinge mechanism 31.

[0129] For example, the first link 311 rotates around the first rotation center of the first end 311a (i.e., the center of the first shaft hole 31111), and the second link 312 rotates around the second rotation center of the second end 311b (i.e., the center of the second shaft hole 31114). The extension direction of the first sliding groove 31133 is parallel to the line connecting the first rotation center and the second rotation center, which helps to make full use of the space between the first shaft hole 31111 and the second shaft hole 31114, so that the slider 3131 can move a longer path in a limited space, thereby driving the first link 311 and the second link 312 to move a longer stroke, effectively improving the lifting effect of the fourth end 312b of the hinge mechanism 31. In some examples, the distance between the first rotation center (i.e., the center of the first shaft hole 31111) and the second rotation center (i.e., the center of the second shaft hole 31114) can be equal to the distance between the third rotation center (i.e., the center of the third shaft hole 31221) and the fourth rotation center (i.e., the fourth shaft hole 31224), which is beneficial to improving the transmission efficiency within the hinge mechanism 31. For example, the distance between the first rotation center (i.e., the center of the first shaft hole 31111) and the second rotation center (i.e., the center of the second shaft hole 31114) is 115mm, and the distance between the third rotation center (i.e., the center of the third shaft hole 31221) and the fourth rotation center (i.e., the fourth shaft hole 31224) can also be 115mm. The distance from the rotation center of the sixth end 313b (i.e., the center of the fifth shaft hole 3132) to the slider 3131 (e.g.) Figure 10 The distance between the two ends (as shown) is 75mm. When the slider 3131 rotates 52.457° around the sixth end 313b, the fourth end 312b can be raised by 100mm within 540ms. The hinge mechanism 31 can realize the rapid unfolding process.

[0130] Please refer to the following: Figure 7 , Figures 15 to 17 , Figure 15 yes Figure 7 The diagram shows an exploded view of the locking element 315. Figure 16 yes Figure 6 A cross-sectional schematic diagram of a portion of the hinge mechanism 31 shown. Figure 17 yes Figure 6 A cross-sectional schematic diagram of part of the hinge structure when the slider 3131 is in the third position 3113c.

[0131] In some embodiments, the vehicle 1000 may include a locking member 315, which may be located between the second end 311b and the third end 312a. The locking member 315 has a locked state and an unlocked state. When the locking member 315 is in the locked state, the second end 311b and the third end 312a are locked, making the second end 311b and the third end 312a relatively fixed. When the locking member 315 is in the unlocked state, the second end 311b and the third end 312a are unlocked. By setting the locking member 315, the second end 311b and the third end 312a can be locked. When the hinge mechanism 31 does not need to move, the relative position of the second end 311b and the third end 312a can be locked, ensuring the stability of the position of the hinge mechanism 31 each time it returns to the retracted state. This increases the possibility of reusing the hinge mechanism 31 and also improves the flexibility of opening and closing the hinge mechanism 31.

[0132] For example, the locking member 315 is set to correspond to the third position 3113c. When the slider 3131 is in the third position 3113c, the locking member 315 is in the locked state; when the slider 3131 leaves the third position 3113c, the locking member 315 is in the unlocked state. It can be understood that by setting the locking member 315 to correspond to the third position 3113c, the hinge mechanism 31 switches between the locked and unlocked states as the position of the slider 3131 changes, making the locking and unlocking process of the hinge mechanism 31 simple to implement and easy to control.

[0133] The second sliding groove 31134 is an arc groove, which allows the first connecting rod 311 to remain stationary relative to the second connecting rod 312, regardless of whether the slider 3131 moves from the second position 3113b to the third position 3113c, or from the third position 3113c to the second position 3113b. This helps to ensure the stability of the relative position between the second end 311b and the third end 312a, thereby ensuring that the locking effect of the locking member 315 is the same each time, and supporting the reuse of the locking member 315 for multiple locking and unlocking.

[0134] When the slider 3131 is in the third position 3113c, the second plate 3112 and the third plate 3121 are at least partially facing each other, and the locking member 315 is located between the second plate 3112 and the third plate 3121. The at least partially facing arrangement of the second plate 3112 and the third plate 3121 can be such that at least part of the projection of the second plate 3112 onto the plane of the third plate 3121 is located within the third plate 3121. This arrangement ensures the locking effect of the locking member 315, and the location of the locking member 315 between the second plate 3112 and the third plate 3121 also helps to fully utilize the space between them, improving the compactness of the hinge mechanism 31 structure.

[0135] In some embodiments, the locking member 315 may include a movable block 3151 and an elastic member 3152; when the slider 3131 is in the third position 3113c, it abuts against one end of the movable block 3151 that extends into the limiting hole 31121, and the other end of the movable block 3151 extends into the locking hole 31211, the elastic member 3152 is compressed, and the locking member 315 is in a locked state; when the slider 3131 leaves the third position 3113c, it separates from the movable block 3151, and the movable block 3151 disengages from the locking hole 31211 under the elastic force of the elastic member 3152. When slider 3131 is in the third position 3113c, elastic element 3152 can be compressed, and moving block 3151 can be pushed into locking hole 31211, thereby locking the second end 311b and the third end 312a. When slider 3131 leaves the third position 3113c, moving block 3151 can be reset under the elastic force of elastic element 3152, releasing the lock on the second end 311b and the third end 312a. By setting elastic element 3152, the structure of locking element 315 is simplified, and the unlocking and locking process is achieved by the cooperation of elastic element 3152 and slider 3131. This is simple and easy to implement, and no additional device is needed to control the unlocking and locking of locking element 315. This helps to reduce the structural complexity and manufacturing cost of hinge mechanism 31, and also helps to improve the reusability of hinge mechanism 31 and reduce the operational difficulty of reusing hinge mechanism 31.

[0136] For example, the locking member 315 further includes a fixing cover 3153, which is fixed to the second end 311b. The fixing cover 3153 has a receiving space 31531 and a through hole 31532. The receiving space 31531 is located between the fixing cover 3153 and the second end 311b. The through hole 31532 connects the receiving space 31531 and the external space of the fixing cover 3153. The elastic member 3152 is located in the receiving space 31531. When the locking member 315 is in the locked state, the elastic member 3152 abuts against one end of the moving block 3151 and the fixing cover 3153, and the other end of the moving block 3151 passes through the through hole 31532 and extends into the locking hole 31211.

[0137] By setting the fixing cover 3153, the locking member 315 can be fixed to the first connecting rod 311 through the fixing cover 3153, which improves the reliability and stability of the connection between the locking member 315 and the first connecting rod 311, and improves the stability of the internal structure of the hinge mechanism 31.

[0138] In some examples, the movable block 3151 may include an abutment portion 31511, a stop portion 31512, and a locking portion 31513 connected in sequence. The dimensions of the abutment portion 31511 and the locking portion 31513 in the second direction Y are both smaller than the dimensions of the stop portion 31512 in the second direction Y. When the locking member 315 is in the unlocked state, the abutment portion 31511 extends into the limiting hole 31121, the stop portion 31512 is located in the limiting groove 31122, and the elastic member 3152 surrounds the outer periphery of the locking portion 31513 and is located between the stop portion 31512 and the fixing cover 3153. When the locking member 315 is in the locked state, the elastic member 3152 abuts against the stop portion 31512 and the fixing cover 3153, and the locking portion 31513 extends into the locking hole 31211. By setting the dimensions of the abutment portion 31511 and the locking portion 31513 in the second direction Y to be smaller than the dimensions of the stop portion 31512 in the second direction Y, the stop portion 31512 can act as a limit, ensuring that the locking member 315 is in the same position when it is in the unlocked state, and also ensuring the compression effect of the moving block 3151 on the elastic member 3152. In addition, by setting the stop portion 31512 to be located in the limiting groove 31122 when the locking member 315 is in the unlocked state, it is beneficial to improve the compactness of the hinge mechanism 31 arrangement when the locking member 315 is installed between the second end 311b and the third end 312a.

[0139] For example, when the locking member 315 is in the locked state, the central axis of the limiting hole 31121 coincides with the central axis of the locking hole 31211. When the locking member 315 is in the unlocked state, the central axis of the limiting hole 31121 and the central axis of the locking hole 31211 are spaced apart. By setting the central axis of the limiting hole 31121 to coincide with the central axis of the locking hole 31211 when the locking member 315 is in the locked state, the complexity of the moving block 3151 structure can be effectively reduced. The moving path of the moving block 3151 can be parallel to the central axis of the limiting hole 31121, which helps to reduce the space occupied by the moving block 3151.

[0140] Please refer to it again. Figure 6 In some embodiments, the drive mechanism 32 may include a drive member 321, and a drive rod 313 may be driveably connected to the drive member 321. The drive member 321 is used to output a first force F1 or a second force F2 to the sixth end 313b. The drive member 321 may be a structural component such as a motor or pneumatic motor; this embodiment does not limit its application. For example, the drive member 321 may be a motor, and the output shaft of the motor may be inserted into the fifth shaft hole 3132 of the sixth end 313b (e.g., ...). Figure 7 As shown, the drive unit 321 and the drive rod 313 are connected in a transmission manner.

[0141] Please refer to the following: Figure 1 , Figure 2 and Figure 6 As shown, when the pop-up device 300 is applied inside the vehicle 1000, the drive unit 321 can be electrically connected to the controller 600. When the information transmitted by the radar 500 meets the lifting conditions, the controller 600 controls the drive unit 321 to output a first force F1, which drives the drive rod 313 to rotate in the first rotation direction, thereby increasing the distance between the lifting end 22 of the cover 200 and the frame 100, increasing the buffer space between the cover 200 and the frame 100, and realizing the anti-collision protection of the vehicle 1000.

[0142] The controller 600 can also be used to respond to the retraction signal, control the drive unit 321 to output a second force F2, drive the drive rod 313 to rotate in the second rotation direction, thereby driving the raised end 22 of the cover 200 to move toward the frame 100, and realize the reset of the cover 200.

[0143] In this embodiment, the lifting and retraction of the pop-up device 300 can be achieved by controlling the output force of the driving component 321. The reset process of the pop-up device 300 is easy to achieve, without requiring the user to manually press the cover 200. The actions of the pop-up device 300 have high repeatability and a high degree of automation. Furthermore, in this embodiment, for example, during the pop-up process of the pop-up device 300, the driving rod 313 rotates along the first rotation direction, and the slider 3131 moves from the third position 3113c through the second position 3113b to the first position 3113a, first unlocking the locking component 315, and then achieving the lifting process. As another example, during the retraction process of the pop-up device 300, after the driving component 321 outputs the second force F2, the driving rod 313 rotates along the second rotation direction, and the slider 3131 moves from the first position 3113a through the second position 3113b to the first position 3113a. 113b moves to the third position 3113c, first realizing the retraction process of the hinge mechanism 31, and then realizing the locking process of the hinge mechanism 31. The internal components of the entire pop-up device 300 have a high degree of cooperation, and can smoothly realize the pop-up and retraction process. The hinge mechanism 31 can be unlocked or locked during the movement of the slider 3131, which simplifies the structural complexity of the pop-up device 300. There is no need to set up an additional device to control unlocking or locking, which reduces the control difficulty of the pop-up device 300, making the pop-up device 300 easy to repeat and highly reliable. For example, the fourth end 312b of the pop-up device 300 provided in this application embodiment can be raised by 100mm within 540ms. That is, the raised end 22 of the cover 200 can be lifted by 100mm within 540ms, which meets the actual need for the pop-up device 300 to quickly respond and drive the raised end 22 of the cover 200 to pop up, so as to form a collision protection for pedestrians. In some other embodiments, by changing the included angle, size and other related settings between the internal components of the hinge mechanism 31, different lifting effects of the raised end 22 of the cover 200 can also be achieved. This application embodiment does not limit this and can be changed according to actual needs.

[0144] For example, the drive mechanism 32 may include a torsion spring (not shown in the figures), which may be elastically connected to the drive member 321 and the drive rod 313. It is understood that, in this embodiment, by providing a torsion spring, the torsion spring can also undergo elastic deformation when the drive rod 313 rotates, providing additional torque to the drive rod 313 to ensure that the torque provided by the drive mechanism 32 is sufficient to meet actual usage requirements.

[0145] In some other embodiments, the first link 311 may not include the second plate 3112, and the second link 312 may not include the third plate 3121. That is, the guide rail 3113 may not include the third position 3113c, and the locking member 315 may be set corresponding to the second position 3113b. When the slider 3131 is in the second position 3113b, the locking member 315 is in a locked state, and when the slider 3131 leaves the second position 3113b, the locking member 315 is in an unlocked state. By aligning the locking member 315 with the second position 3113b, the locking state of the locking member 315 can be switched during the reciprocating motion of the slider 3131. The hinge mechanism 31 switches between the locked and unlocked states as the position of the slider 3131 changes, making the locking and unlocking process of the hinge mechanism 31 simple to implement and easy to control.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0147] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0148] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
