Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an interior panel structure and vehicle. Background Technology

[0002] A car consists of major structures such as a body frame, chassis, powertrain, and transmission. The body frame provides support and protection for the vehicle, while the chassis bears the components and ensures driving stability. The interior, as an important part of the car's interior, uses panels to conceal or display functional structures such as cup holders and ashtrays, combining aesthetics and practicality.

[0003] Currently, there are two main types of locking mechanisms for automotive interior panels when closed: one is to use spring preload to achieve locking, using the elastic force of the spring to maintain the closed position of the panel; the other is to use a latch structure for locking, using the cooperation of the latch and the latch to fix the panel.

[0004] However, existing locking mechanisms have some problems. While the spring preload structure is simple in design, the elastic element of the spring occupies a large space, limiting the flexibility of interior design. In addition, the spring is prone to aging and deformation after prolonged use, resulting in a decrease in the elastic force provided, causing the panel to open under its own weight, affecting the panel's closing effect. The latch structure, on the other hand, requires more parts, which not only increases the complexity of the components but also raises manufacturing costs and assembly difficulty. Utility Model Content

[0005] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide an interior panel structure and vehicle, which intends to achieve the opening or closing of the panel without increasing the internal space occupation through a novel design of the linkage transmission structure between the panel and the drive element, and to stably support the panel when it is closed to prevent the panel from opening on its own, so as to solve the problems of complex locking structure, large space occupation and insufficient locking stability of the panel in the prior art.

[0007] To achieve the above objectives, in a first aspect, this utility model provides an interior panel structure, comprising: The base has a storage compartment; the base has an opening that connects to the storage compartment. Panel, with an opening on the base that allows the panel to be movably connected; A drive assembly is mounted on the base; the drive assembly is movably connected to a panel to move the panel between a closed position of the enclosed storage compartment and an open position of the exposed storage compartment; the drive assembly includes a drive arm and a transmission linkage. One end of the drive arm is used to connect to the driver, and the other end of the drive arm is movably connected to one end of the transmission link; the end of the transmission link away from the drive arm is movably connected to the panel. A rotation axis and a reference plane are defined. The rotation axis passes through the rotation center of the drive arm and is used to enable the drive arm to rotate in a plane perpendicular to the rotation axis. The reference plane is perpendicular to the rotation axis. When the panel is moved to the closed position, the rotation center of the drive arm and the projections of the two movable connection points located at both ends of the transmission link onto the reference plane are on the same straight line.

[0008] In existing technologies, panels typically utilize spring preload to lock when closed. This involves pressing the panel against a limiting structure at the opening using the spring's elastic force, thus maintaining the panel's closure. However, because the spring needs to deform to generate this elastic force, it occupies a significant amount of space after deformation. Allowing this space restricts interior design flexibility. Furthermore, springs age over time, reducing the elastic force generated after deformation. This results in insufficient preload pressure provided by the spring to the panel, allowing the panel's weight to overcome the elastic force and open. This affects the panel's closing effect. When the panel is closed, it may be locked using a latch structure. This involves the latch and the latch working together to prevent the panel from moving in the opening direction, thus limiting and fixing the panel in the closed position. The latch structure requires more parts, including not only the latch and the latch, but also the mechanism that drives the latch to extend and retract, as well as the structure that fixes the latch and the latch. This increases the complexity of the parts, raises the component costs, and increases the manufacturing cost of the interior panel structure. Furthermore, each component needs to be assembled into its corresponding position, and the latch also needs to be installed opposite to the latch, making the assembly complex and precise. This application, through the above-mentioned solution, achieves the opening and closing of the panel by cooperating with the drive arm and transmission link in the drive assembly. When the panel moves to the closed position, the rotation center of the drive arm and the movable connection points at both ends of the transmission link are projected onto the same straight line, forming a mechanical dead point. Thus, without adding extra parts, the drive assembly that realizes the opening and closing of the panel can be directly used to keep the panel stably in the closed position. The structure is simple, and the locking stability will not decrease due to aging after long-term use. The interior of the car will not occupy space due to the additional panel locking structure.

[0009] In some embodiments of this application, the lower panel in the open position is positioned lower than the lower panel in the closed position, and the drive component is located inside the storage compartment on the side closer to the open position. When the panel is moved to the closed position, the drive arm is located on the side of the vertical direction closest to the closed position where its rotation center is located.

[0010] In this technical solution, the structural design places the opening at the top of the base. The panel opens by moving downwards, and the drive assembly can only open the panel by pulling downwards. At the mechanical dead point, the drive arm and transmission link do not overlap, thus reducing the length of the transmission link needed to connect the drive arm and the panel. This reduces the material and weight of the transmission link, lowering the manufacturing cost of the drive assembly and allowing the actuator to easily drive the transmission link via the drive arm, while also reducing the space occupied by the transmission link during movement. On the other hand, when the panel is closed, the drive arm is tilted, causing it to tend to swing downwards under its own weight. This is opposite to the direction the drive arm needs to move when opening the panel. Driven by the actuator, the drive arm first needs to rotate upwards to overcome its own weight and rotate from the tilted state to the vertical state. Only after crossing the vertical state can the drive arm swing downwards to open the panel. The drive arm's own weight can also prevent it from rotating in the direction of opening the panel to a certain extent, keeping the panel stably in the closed state and further improving the stability of the panel's closing and locking mechanism.

[0011] In some embodiments of this application, when the panel is moved to the closed position, the panel is embedded in the opening.

[0012] In the technical solution, the structural design allows the panel to fit tightly against the base when closed, effectively hiding the storage compartment and maintaining the cleanliness and aesthetics of the vehicle interior. Furthermore, due to the embedded design of the panel, the gap between the panel and the base can be reduced, decreasing the possibility of dust and debris entering and improving the overall quality of the interior. On the other hand, when the drive arm and transmission linkage start pulling the panel open from the dead point position, the panel can be dislodged downwards from the opening, thus moving downwards to the open position.

[0013] In some embodiments of this application, the lower panel in the open position is positioned higher than the lower panel in the closed position, and the drive component is located inside the storage compartment on the side away from the open position.

[0014] In this technical solution, the structural design provides an alternative way to open the panel. The opening is located at the bottom of the base, and the panel opens by moving upwards. The drive component is located at the bottom of the storage compartment, and it can only open the panel by pushing upwards. This design can be adapted to different vehicle models and interior layout requirements, making the interior panel structure more flexible. On the other hand, when the panel is closed, the drive arm and transmission link, which are at a mechanical dead point, overlap to a certain extent, and the drive arm is located below its rotation center. The drive arm can only rotate upwards to push the door panel open via the transmission link. Under its own weight, the drive arm tends to swing downwards, which is opposite to the direction the drive arm needs to rotate when opening the panel. The drive arm can, to a certain extent, prevent the drive arm from rotating in the direction of opening the panel by its own weight, keeping the panel stably in the closed state and further improving the stability of the panel closing and locking.

[0015] In some embodiments of this application, the base is provided with a slide groove, and the panel is provided with a slide block; the slide block is slidably connected to the slide groove; and the transmission link is movably connected to the slide block.

[0016] In the technical solution, the structural design provides a stable guide for the movement of the panel, enabling the panel to move more smoothly and steadily during opening and closing, avoiding jamming or shaking; on the other hand, the cooperation between the slide and the slide groove can limit the movement trajectory of the panel, ensuring that the panel accurately reaches the closed position, forming a mechanical dead point, and improving the stability and reliability of the interior panel structure.

[0017] In some embodiments of this application, when the panel is moved to the closed position, the panel closes the opening; when the panel is moved to the open position, the panel is located inside the storage compartment.

[0018] In the technical solution, the structural design allows the panel to move into the storage compartment when it is opened, thus hiding it inside the base without occupying additional interior space and improving space utilization. On the other hand, the direction of movement when the panel is opened allows the slide to be opened on the surface inside the storage compartment, eliminating the need to install a slide structure on the base, and making more effective use of the structural space.

[0019] In some embodiments of this application, the slide is provided with a sliding rod, which is slidably and rotatably disposed in a slide groove; when the panel is moved to the open position, the panel is flipped to the side where the opening is away from the closed position.

[0020] In the technical solution, the structural design allows the panel to be flipped open and completely frees up the space inside the storage compartment opposite the opening, so that the panel occupies less space after being stored in the storage compartment, thereby improving the utilization rate of the space inside the storage compartment.

[0021] In some embodiments of this application, the slide groove includes a first slide groove and a second slide groove, and the slide block includes a first slide block and a second slide block; the first slide block is slidably and rotatably disposed in the first slide groove, and the second slide block is slidably and rotatably disposed in the second slide groove.

[0022] In the technical solution, the structural design achieves control of the movement trajectory at both ends of the panel through the cooperation of two sliding blocks and sliding grooves, further enhancing the stability and flexibility of the panel movement, improving the positioning accuracy of the panel during opening and closing, and ensuring that the panel can accurately form a mechanical dead point in the closed position; on the other hand, it can also evenly distribute the force on the panel during the movement, reduce local stress concentration, and extend the service life of the interior panel structure.

[0023] In some embodiments of this application, the driver includes a drive motor and a drive gear; the drive gear is connected to the drive motor and is driven to rotate by the drive motor; a driven gear is mounted on the drive arm, and the driven gear is coaxial with the rotation center of the drive arm; a toothed synchronous belt is mounted between the drive gear and the driven gear; the diameter of the drive gear is smaller than the diameter of the driven gear.

[0024] In the technical solution, the structural design has high transmission efficiency and precision, enabling smooth and accurate driving. It effectively transmits the rotational motion of the drive motor to the drive arm, thereby driving the panel to move. On the other hand, since the diameter of the drive gear is smaller than that of the driven gear, it can play a role in speed reduction and torque increase during transmission, allowing the drive arm to drive the panel with greater torque. This ensures that the panel can overcome various resistances during opening and closing, smoothly reach the designated position, and improve the stability and reliability of the interior panel structure.

[0025] Secondly, this application provides a vehicle, including: Body; The interior panel structure shown above is installed inside the vehicle body.

[0026] In the technical solution, applying the aforementioned interior panel structure to vehicles can effectively solve the problems of the interior panel sagging when closed and the surface difference between it and surrounding parts, thereby improving the quality and aesthetics of the vehicle interior, enhancing the user experience, reducing the number of parts and space occupation by optimizing the locking structure of the interior panel, reducing manufacturing costs and assembly difficulty, improving the reliability and stability of the vehicle interior, and thus enhancing the vehicle's competitiveness in the market.

[0027] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] It should be noted that in the automotive industry, interior components are an important part of the car's interior. Functional structures 100 such as cup holders and ashtrays are usually located within interior components. These components typically have panels 300 installed on them. These panels 300 can open or close openings 202 within the interior components, thus concealing these functional structures 100 within the components and ensuring their aesthetics; or they can expose these functional structures 100 through the openings 202, allowing them to be accessed or used, thus ensuring the practicality of the interior components.

[0033] In existing technology, panel 300 is typically locked by spring preload when closed. That is, the elastic force of the spring presses panel 300 against the limiting structure of opening 202, thus keeping panel 300 closed to opening 202. Because the spring needs to deform to generate elastic force, it occupies a significant amount of space after deformation. To allow for the spring's deformation, the interior design is significantly constrained, affecting its flexibility. Furthermore, springs are prone to aging after prolonged use, leading to a decrease in the elastic force generated after deformation. This results in insufficient preload pressure provided by the spring to panel 300, causing panel 300's gravity to overcome the elastic force and close. Opening the panel 300 affects its closing effect. When closed, the panel 300 is locked using a latch structure. This means that the latch and the latch work together to prevent the panel 300 from moving in the opening direction, thus limiting and fixing the panel 300 in the closed position. The latch structure requires more parts, including not only the latch and the latch, but also the mechanism that drives the latch to extend and retract, as well as the structure that fixes the latch and the latch. This increases the complexity of the parts, increases the cost of components, and increases the manufacturing cost of the interior panel structure. In addition, each part needs to be assembled into its corresponding position, and the latch also needs to be installed opposite to the latch, which makes the assembly complex and precise.

[0034] Based on this, this application proposes an interior panel structure. When the panel 300 is in the closed position, the drive arm 401 and transmission link 402 in the drive assembly 400 that drives the panel 300 to open or close are set at the mechanical dead point, thereby achieving self-locking of the panel 300 when it is closed. This solves the problems of complex locking structure, large space occupation, and insufficient locking stability of the panel 300 in the prior art.

[0035] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0036] See Figures 1 to 7 In one illustrative embodiment of the interior panel structure of this application, the interior panel structure includes a base 200, which is the main structure of the interior components. The vehicle body has a cabin, and the base 200 is typically located within the cabin. A storage compartment 201 is provided inside the base 200, which is used to accommodate and house functional structures 100 such as cup holders and ashtrays. An opening 202 is provided in the base 200, which communicates with the storage compartment 201, allowing access to the cup holders, ashtrays, and other functional structures 100 within the storage compartment 201 through the opening 202.

[0037] See Figures 1 to 6In some embodiments, the interior panel structure also includes a panel 300, which is movably connected to an opening 202 on the base 200, so that the panel 300 can open or close the opening 202 to expose or hide the functional structures 100 such as cup holders and ashtrays in the storage compartment 201.

[0038] See Figures 1 to 6 In some embodiments, the interior panel structure further includes a drive assembly 400, which is disposed on the base 200 and movably connected to the panel 300. Driven by the drive assembly 400, the panel 300 moves between a closed position and an open position. When the panel 300 moves to the open position, the panel 300 opens the opening 202, exposing the storage compartment 201, thereby allowing access to and use of functional structures 100 such as cup holders and ashtrays within the storage compartment 201; when the panel 300 moves to the closed position, the panel 300 closes the opening 202, sealing the storage compartment 201 and concealing the functional structures 100 such as cup holders and ashtrays within the storage compartment 201.

[0039] See Figures 1 to 6 In some embodiments, the drive assembly 400 includes a drive arm 401, a transmission link 402, and a driver 403. The driver 403 is connected to one end of the drive arm 401, thereby enabling the drive arm 401 to rotate under the drive of the driver 403. The other end of the drive arm 401 is movably connected to one end of the transmission link 402, and the end of the transmission link 402 away from the drive arm 401 is movably connected to the panel 300, so that the rotating drive arm 401 drives the panel 300 to move through the transmission link 402, thereby enabling the panel 300 to move between a closed position and an open position.

[0040] See Figure 2 In some embodiments, the interior panel structure defines a rotation axis 500 and a reference plane. The rotation axis 500 passes through the rotation center of the drive arm 401, causing the drive arm 401 to rotate in a plane perpendicular to the rotation axis 500, and the transmission link 402 also moves in a plane perpendicular to the rotation axis 500. The reference plane is a plane perpendicular to the rotation axis 500.

[0041] See Figures 4 to 5In some embodiments, when the panel 300 is moved to the closed position, the rotation center of the drive arm 401 and the projections of the two movable connection points located at both ends of the transmission link 402 onto the reference plane are aligned on the same straight line, causing the crank-rocker structure formed by the drive arm 401 and the transmission link 402 to be in a dead-point position. When the panel 300 is in the closed position, the drive arm 401 and the transmission link 402 stop at the dead-point position. The crank-rocker structure formed by the drive arm 401 and the transmission link 402 cannot continue to operate through the dead-point. No matter how large the reaction force of the panel 300 on the crank-rocker structure is, it cannot make the crank-rocker structure operate. The crank-rocker structure stably supports the panel 300, keeping the panel 300 in the closed position, stably closing the opening 202 on the base 200, and stably sealing the storage compartment 201.

[0042] Through the above-described solution, the drive assembly 400 drives the panel 300 to open and close. At the same time, by utilizing the drive arm 401 and transmission link 402 in the drive assembly 400 to be at the dead point position when the panel 300 moves to the closed position, the panel 300 is stably held in the closed position. No additional structure is needed to lock the panel 300 in the closed position, which simplifies the interior panel structure, reduces the space occupied by the structure, and enables stable use for a long time.

[0043] See Figures 4 to 6 In some embodiments, the lower panel 300 in the open position is lower than the lower panel 300 in the closed position. This structural design provides an opening method for the panel 300, which moves from the closed position to the open position by moving downwards. This opening method of the panel 300 allows the opening 202 to be located at the top of the base 200, and the opening 202 can be oriented upwards to meet the need for items to be placed from top to bottom into the functional structure 100 of the storage compartment 201.

[0044] Furthermore, the drive assembly 400 is located within the storage compartment 201 on the side near the open position, thus distancing the drive assembly 400 from the closed position of the panel 300. When the drive assembly 400 drives the panel 300 to open, the panel 300 needs to be pulled towards the drive assembly 400 to move from the closed position to the open position. This structural design requires the drive arm 401 to move towards the open position of the panel 300 in order to pull the panel 300 open via the transmission link 402. Therefore, when the panel 300 is in the closed position, the drive arm 401 and the transmission link 402, which are at their dead points, are not overlapped. The transmission link 402 is positioned between the drive arm 401 and the panel 300. The transmission link 402 requires only a shorter length to connect the drive arm 401 and the panel 300, reducing the material and weight of the transmission link 402, resulting in less space occupied when the transmission link 402 moves, and also reducing the manufacturing cost of the drive assembly 400. In addition, the drive load of the actuator 403 when pulling the transmission link 402 through the drive arm 401 is reduced, thereby making it easier to open the drive panel 300.

[0045] Furthermore, when panel 300 moves to the closed position, drive arm 401 is located on the side of its rotation center in the vertical direction closer to the closed position, causing drive arm 401 to tilt away from the open position of panel 300. This structural design means that when panel 300 is opened, drive arm 401 rotates towards the open position. During this rotation, drive arm 401 needs to first rotate upward to a vertical position, then swing downward after passing the vertical position. When drive arm 401 rotates upward to a vertical position, it needs to overcome its own weight. When panel 300 is in the closed position, drive arm 401 tends to swing downward under its own weight, which is opposite to the direction drive arm 401 needs to move when opening panel 300. Drive arm 401 can, to a certain extent, prevent drive arm 401 from rotating towards opening panel 300 through its own weight, keeping panel 300 stably in the closed state, further improving the stability of panel 300's closing and locking.

[0046] See Figures 4 to 5 In some embodiments, when panel 300 is moved to the closed position, it is embedded in opening 202. This structural design allows panel 300 to be embedded in base 200 when closed, effectively concealing storage compartment 201 and ensuring a smooth outer surface of base 200, thus improving the neatness and aesthetics of the vehicle interior. Furthermore, the embedded design of panel 300 minimizes the gap between the edge of panel 300 and opening 202, reducing the likelihood of dust and debris entering storage compartment 201 and enhancing the overall quality of the interior.

[0047] Furthermore, as the drive arm 401 moves from the dead position toward the open position, the angle between the drive arm 401 and the transmission link 402 gradually decreases from 180 degrees. This reduces the distance between the movable connection point of the transmission link 402 on the panel 300 and the rotation center of the drive arm 401, causing the panel 300 to move downwards, disengage from the opening 202, and enter the storage compartment 201. This allows the panel 300 to be opened while embedded in the opening 202, and the opening of the panel 300 is not obstructed by the opening 202.

[0048] In some embodiments, the lower panel 300 in the open position is positioned higher than the lower panel 300 in the closed position. This structural design provides an alternative opening method for the panel 300, which moves from the closed position to the open position by moving upwards. This opening method of the panel 300 allows the opening 202 to be located at the bottom of the base 200, and the opening 202 can be arranged laterally to meet the need for items to be placed laterally into the functional structure 100 within the storage compartment 201.

[0049] Furthermore, the drive assembly 400 is located within the storage compartment 201 on the side away from the open position, making the drive assembly 400 close to the closed position of the panel 300. When the drive assembly 400 drives the panel 300 to open, the panel 300 needs to be pushed away from the drive assembly 400 to move the panel 300 from the closed position to the open position. This structural design requires the drive arm 401 to move closer to the open position of the panel 300 in order to push the panel 300 open via the transmission link 402. This results in a certain degree of overlap between the drive arm 401 and the transmission link 402 when the panel 300 is in the closed position, with the drive arm 401 located below its rotation center. When panel 300 is open, drive arm 401 rotates towards the open position. During this rotation, drive arm 401 needs to rotate upward and overcome its own weight. When panel 300 is in the closed position, drive arm 401 tends to swing downward under its own weight. This is opposite to the direction drive arm 401 needs to move when opening panel 300. Drive arm 401 can prevent drive arm 401 from rotating towards opening panel 300 to a certain extent by its own weight, so that panel 300 is stably kept in the closed state, further improving the stability of panel 300's closing and locking.

[0050] See Figures 1 to 7In some embodiments, the base 200 is equipped with a slide groove 203, and the panel 300 is equipped with a slide block 301. The slide block 301 is slidably connected to the slide groove 203, allowing it to move along the slide groove 203. A transmission link 402 is movably connected to the slide block 301, thereby connecting the transmission link 402 to the panel 300 via the slide block 301. This structural design, through the cooperation of the slide block 301 and the slide groove 203, provides stable guidance for the movement of the panel 300, enabling the panel 300 to move more smoothly and steadily during opening and closing, avoiding jamming or shaking. Furthermore, the cooperation of the slide block 301 and the slide groove 203 restricts the movement trajectory of the panel 300, ensuring that the panel 300 accurately reaches the closed position, forming a mechanical dead point, and improving the stability and reliability of the interior panel structure.

[0051] See Figures 4 to 6 In some embodiments, when panel 300 is moved to the closed position, it closes opening 202. When panel 300 is moved to the open position, it is located within storage compartment 201. This structural design allows panel 300 to move inward into storage compartment 201 when opened, thus concealing it within base 200 when in the open position, without occupying interior space outside base 200, thereby improving space utilization. Furthermore, the inward opening and concealment of panel 300 within storage compartment 201 allows the sliding groove 203 to be formed on the inner surface of storage compartment 201, eliminating the need for additional sliding groove 203 on base 200, and further utilizing structural space more effectively.

[0052] See Figures 3 to 6 In some embodiments, the slide 301 is provided with a sliding rod 302, which is disposed in the slide groove 203. This allows the slide 301 to rotate relative to the slide groove 203 as it moves along the slide groove 203, enabling the panel 300 to flip after opening inwards. When the panel 300 moves to the open position, it flips to the side of the opening 202 away from the closed position, thus removing the panel 300 from the space in the storage compartment 201 directly opposite the opening 202. This structural design allows the panel 300 to be hidden inside the storage compartment 201 by flipping after opening, freeing up space in the storage compartment 201 opposite the opening 202. This facilitates the placement of functional structures 100 such as cup holders and ashtrays in positions opposite the opening 202, improving the usability of the functional structures 100 and eliminating the obstruction of the functional structures 100 by the panel 300. Furthermore, the panel 300 occupies less space after being stored in the storage compartment 201, increasing the utilization rate of the space within the storage compartment 201.

[0053] See Figures 3 to 7In some embodiments, the slide 203 includes a first slide 2031 and a second slide 2032. The slide block 301 includes a first slide block 3011 and a second slide block 3012. The first slide block 3011 is slidably and rotatably disposed in the first slide block 2031, and the second slide block 3012 is slidably and rotatably disposed in the second slide block 2032. The first slide block 3011 and the second slide block 3012 are typically spaced apart and respectively disposed at both ends of the panel 300. This structural design, through the cooperation of two sets of sliding blocks 301 and sliding grooves 203, allows for control of the movement trajectory at both ends of the panel 300. The two movement trajectories enable posture control during panel 300 movement, enhancing both stability and flexibility. On one hand, it ensures that the panel 300 can accurately flip after opening, creating space opposite the opening 202 and improving the utilization of the storage compartment 201. On the other hand, it ensures that the panel 300 can accurately move to the closed position after closing, precisely stopping the drive arm 401 and transmission linkage 402 at the mechanical dead point. Furthermore, during panel 300 movement, force is distributed through the two sliding blocks 301. The pushing and pulling force of the drive assembly 400 on the panel 300 is transmitted to the sliding grooves 203 through the two sliding blocks 301, and the reaction force also acts on the panel 300 through the two sliding blocks 301. This evenly distributes the force on the panel 300 during movement, reducing localized stress concentration and extending the service life of the interior panel structure.

[0054] See Figures 3 to 6 In some embodiments, the driver 403 includes a drive motor 4031 and a drive gear 4032. The drive gear 4032 is connected to the output shaft of the drive motor 4031, causing the drive gear 4032 to rotate under the drive of the drive motor 4031. A driven gear 4033 is mounted on the drive arm 401, and the driven gear 4033 is coaxial with the rotation center of the drive arm 401. A toothed synchronous belt 4034 is installed between the drive gear 4032 and the driven gear 4033, so that the rotating drive gear 4032 drives the driven gear 4033 to rotate through the toothed synchronous belt 4034, thereby realizing the rotation of the drive arm 401. This structural design has transmission efficiency and precision, and can achieve smooth and accurate driving, effectively transmitting the rotational motion of the drive motor 4031 to the drive arm 401, thereby driving the panel 300 to move.

[0055] Furthermore, the diameter of the drive gear 4032 is smaller than the diameter of the driven gear 4033. This gear diameter relationship can reduce speed and increase torque during transmission, enabling the drive arm 401 to drive the panel 300 with greater torque. This ensures that the panel 300 can overcome various resistances during opening and closing, smoothly reach the designated position, and improve the stability and reliability of the interior panel structure.

[0056] Furthermore, to ensure smooth movement of the drive panel 300, two drive arms 401 and two transmission links 402 are provided in the drive assembly 400, forming two sets of crank-rocker structures. These two sets of crank-rocker structures are located on opposite sides of the storage compartment 201, creating a space between the two sets of crank-rocker structures where the storage compartment 201 and the opening 202 are directly opposite each other. The output shaft of the drive motor 4031 extends to both ends and is equipped with two driven gears 4033, which are respectively mounted on the two drive arms 401. A toothed synchronous belt 4034 is installed between each set of drive gears 4032 and driven gears 4033. The two transmission links 402 connect to both sides of the panel 300, allowing the drive motor 4031 to evenly transmit driving force to both sides of the panel 300, enabling smooth movement of the panel 300. The two sets of crank-rocker structures are concealed within the storage compartment 201, without obstructing the installation and use of the functional structure 100.

[0057] Furthermore, the inner wall of the storage compartment 201 is provided with a receiving groove 204, and the driven gear 4033 is disposed in the receiving groove. The drive arm 401 is divided into a first drive section 4011, a bending section 4013, and a second drive section 4012. The first drive section 4011 is connected to the driven gear 4033, and the second drive section 4012 is connected to the transmission link 402. The first drive section 4011 is connected to the second drive section 4012 through the bending section 4013, so that the first drive section 4011 and the second drive section 4012 are staggered in layers. The second drive section 4012 is closer to the inner side of the storage compartment 201 than the first drive section 4011. The first drive section 4011 can be set together with the connected driven gear 4033 in the receiving groove 204, and the driven gear 4033 and a part of the drive arm 401 are hidden, thereby avoiding the driven gear 4033 from colliding with the panel 300 or other structures in the storage compartment 201 during operation, and reducing the space occupied by the part of the drive arm 401 near its rotation center in the width direction of the storage compartment 201.

[0058] Furthermore, this application also provides a vehicle, which includes a body. The body is the core structure of the vehicle, including a chassis and body panels. The chassis provides basic support and driving functions for the vehicle, while the body panels constitute the vehicle's appearance and protect internal components. The vehicle further includes the aforementioned interior panel structure, which is installed inside the body. By integrating the optimized interior panel structure into the vehicle, the problems of the interior panel 300 sagging when closed and the surface difference between it and surrounding parts can be effectively solved, improving the quality and aesthetics of the vehicle interior, enhancing the user experience, and by optimizing the locking structure of the interior panel 300, reducing the number of parts and space occupation, lowering manufacturing costs and assembly difficulty, improving the reliability and stability of the vehicle interior, thereby enhancing the vehicle's competitiveness in the market.
