Description

Technical Field

[0001] This invention relates to the field of driving technology for vehicle interior functional components, specifically to a device for driving components such as vehicle storage box lids and cup holder lids to perform compound movements. Background Technology

[0002] As vehicles become more intelligent and interiors offer higher quality, users are demanding a better user experience from in-vehicle components. Some advanced features, such as automatically lifting cup holders or storage boxes with protective covers, require both the simultaneous rotation of the cover to open and the linear lifting of the built-in platform.

[0003] Currently, a common solution for achieving such complex actions is to use two independent drive devices, such as using one motor to drive the rotating cover and another motor or electromagnetic actuator to drive the lifting body. While this multi-drive solution can achieve the function, it also brings significant drawbacks: First, the system requires two independent power sources, transmission mechanisms, and control circuits, resulting in a complex overall structure, large space occupation, and a significant increase in manufacturing costs and weight; second, the synchronization between the two actions depends entirely on the precise timing matching of the control system, which is highly dependent on control software and sensor feedback, increasing system complexity and failure risk, and making it difficult to guarantee the consistency of actions after mechanical wear during long-term use; finally, the presence of multiple actuators also increases energy consumption and operating noise.

[0004] Therefore, the industry needs a more streamlined, reliable, and easy-to-control solution to achieve coordinated driving of rotation and linear motion, thereby improving the user experience while reducing costs and complexity. Summary of the Invention

[0005] In view of this, the present invention provides a vehicle-mounted single-motor linkage device and vehicle, which aims to achieve the goals of structural simplification, control simplification and motion coordination by synchronously driving rotary motion and linear motion through a single power source.

[0006] The objective of this invention is achieved through the following technical solution: A vehicle-mounted single-motor linkage device includes a motor, a rotating cover, a lifting body, and a linkage gear. The rotating cover has an arc-shaped extending cover groove, and the linkage gear is configured to be driven to rotate by the motor. One end face of the linkage gear has a groove, and one or more drive pins are fixedly mounted on the linkage gear. One or more drive pins are slidably embedded in one or more cover grooves, so that the rotation of the linkage gear can drive the rotating cover to rotate around a fixed axis. The lifting body has a sliding pin, which is slidably embedded in the groove on the end face of the linkage gear, so that the same rotation of the linkage gear can simultaneously drive the lifting body to move along a straight line.

[0007] This device utilizes a single motor and a linkage gear with two integrated output interfaces to achieve mechanical synchronous drive for rotary and linear motion. Its highly simplified structure significantly reduces the number of components, cost, and weight, while improving space utilization. Mechanical coupling ensures a precise and coordinated correspondence between the two motions, enhancing motion consistency. It eliminates the complex synchronization control and sensing requirements of multi-actuator systems, simplifying control logic and making system response more reliable. The transmission is smooth, with low noise, and it is easily designed to meet different performance requirements, providing an efficient and compact solution for achieving complex linkage functions in vehicle spaces.

[0008] Preferably, the groove is an inclined groove whose extending direction forms an angle with the radial direction of the linkage gear.

[0009] The inclined slot structure efficiently converts gear rotation into linear motion. Its inclined surface pushes the sliding pin to generate radial displacement, resulting in high conversion efficiency. The inclined slot angle can be customized to plan specific motion speed curves for the lifting body, meeting diverse functional requirements. This method features a direct and compact structure, strong manufacturing feasibility, and helps ensure smooth and precise motion conversion.

[0010] Preferably, it further includes a transmission assembly, which includes a worm gear connected to the output shaft of the motor, an input gear meshing with the worm gear, and a linkage gear meshing with the input gear.

[0011] Worm gear drives offer a high reduction ratio and a reverse self-locking capability. The high reduction ratio allows for the output of high torque using a small motor, ensuring powerful operation. The reverse self-locking feature allows the device to remain firmly in any position after power failure, preventing accidental movement and enhancing safety and ease of use. This reliable drivetrain structure helps optimize the overall layout.

[0012] Preferably, it also includes a base, on which a guide portion is provided, and the lifting body achieves linear movement by slidingly engaging with the guide portion.

[0013] The base and its guide section provide precise linear motion constraints for the lifting body, preventing swaying and jamming, and ensuring the accuracy of the motion trajectory. As a stable installation platform, the base facilitates modular integration and effectively distributes loads, improving the rigidity and durability of the entire device.

[0014] Preferably, it also includes a bracket, and the rotating cover is rotatably mounted on the bracket via a pivot.

[0015] The bracket and pivot shaft establish a stable center of rotation for the rotating cover, ensuring smooth and stable rotation. The split design facilitates the production, assembly, and maintenance of components, while enhancing the load-bearing capacity and long-term operational reliability of the rotating mechanism.

[0016] Preferably, there are multiple drive pins, and the number of cover grooves is the same as the number of drive pins and they correspond one-to-one.

[0017] The multi-drive-point design improves the force distribution of the rotating cover, reduces single-point stress and wear, and extends its service life. Multiple symmetrical drive points can balance lateral forces, making the rotation smoother and more stable, and improving the balance and reliability of the mechanism.

[0018] Preferably, there are multiple rotating covers, and each rotating cover engages with a drive pin via a cover groove.

[0019] This allows a single drive core to simultaneously control multiple rotating covers, greatly expanding the functional range, such as controlling multiple parallel covers. All cover movements are strictly synchronized, enabling complex multi-objective control with a minimal system, saving cost and space.

[0020] Preferably, the output shaft axis of the motor, the rotation axis of the linkage gear, and the linear motion direction of the lifting body are perpendicular or approximately perpendicular to each other.

[0021] This orthogonal layout makes the device structure extremely compact, minimizing its footprint and making it ideal for space-constrained in-vehicle environments. The clear power transmission path facilitates modular design and integration, providing greater flexibility for vehicle interior layout.

[0022] Preferably, the motor is a drive motor capable of receiving electrical signals and reversing in both directions.

[0023] The reversible motor enables the device to complete a full reciprocating cycle through switching electrical signal polarity, making control simple and direct. This forms the basis for achieving automated bidirectional motion, meets the practical needs of switching the state of onboard functional components, and enhances the level of intelligence.

[0024] A vehicle including an on-board single-motor linkage device as described in any of the preceding claims.

[0025] Integrating this device into a vehicle enables a single module to drive multiple interior functional components in a coordinated "flipping + lifting" motion, significantly enhancing the cabin's technological feel and user experience. Its streamlined, reliable, and easy-to-control features facilitate its adoption in vehicles, increasing the product's practicality and appeal.

[0026] The advantages of this invention compared to the prior art are: 1. Simplified Structure and Cost Advantages: By using a single motor in conjunction with a linkage gear that integrates dual output interfaces, the two independent drive systems in the traditional solution are replaced. This significantly reduces the number of drive motors, transmission components, and corresponding fixed structures, thereby reducing the material cost, overall weight, and assembly complexity of the device, and making the structural layout more compact, saving valuable vehicle space.

[0027] 2. Reliable Motion Synchronization: The opening of the rotating cover and the lifting of the lifting body originate from the same rotational input and are rigidly coupled through two sets of mechanical pairs: the drive pin and the cover slide groove, and the sliding pin and the gear slide groove. This mechanical linkage ensures a definite and inseparable phase and position correspondence between the two output movements, achieving inherent motion coordination and consistency without the need for electronic synchronization control, thus improving the smoothness and visual quality of the composite motion.

[0028] 3. Simplified Control and Enhanced Reliability: Since only simple start-stop and steering control of a single motor is required to complete the complex "rotation-linear" dual-stroke operation, the hardware circuitry and software logic of the control system are greatly simplified. This reduces reliance on sensor feedback and minimizes potential circuit or control program failure points, thereby contributing to improved overall system reliability and long-term stability.

[0029] 4. Self-locking and position-holding capabilities: When using a transmission assembly including a worm gear, the reverse self-locking characteristic of the worm gear transmission can be utilized. This allows the device to reliably remain at any position within its stroke after the motor is powered off, effectively preventing accidental movement of the rotating cover or lifting body due to vibration or external force, thus enhancing safety and user experience.

[0030] 5. Excellent scalability and adaptability: By setting multiple drive pins and corresponding cover grooves, larger or heavier rotating covers can be smoothly driven. Furthermore, a single linkage gear can simultaneously drive multiple independent rotating covers, achieving more complex functional layouts without increasing the number of drive cores, demonstrating excellent functional expansion potential. The compact orthogonal layout of the device also easily adapts to different vehicle interior installation spaces. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0050] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0051] This embodiment provides a vehicle-mounted single-motor linkage device, including: Motor 1; Four rotating covers 2, each of which has an arc-shaped sliding groove 21; Lifting body 3; A linkage gear 4 is configured to be driven to rotate by a motor 1; Among them, a slanted groove 41 is opened on one end face of the linkage gear 4, and four drive pins 42 are also circumferentially and evenly fixed on the linkage gear 4. The four drive pins 42 are slidably embedded in the cover grooves 21 of the four rotating covers 2, so that the rotation of the linkage gear 4 can synchronously drive the four rotating covers 2 to rotate around their respective fixed axes. A sliding pin 31 is fixedly installed on the lifting body 3. The sliding pin 31 is slidably embedded in the inclined groove 41 on the end face of the linkage gear 4, so that the same rotation of the linkage gear 4 can simultaneously drive the lifting body 3 to move in a straight line direction.

[0052] In this embodiment, the four rotating covers 2 are arranged in pairs and opposite each other to form a pair of openable covers that can be opened or closed in opposite directions, which are commonly used in hidden cup holders or storage boxes in vehicles.

[0053] By employing a single motor 1 as the power source and innovatively integrating two mechanical output interfaces—a drive pin 42 and an end face groove 41—on a single linkage gear 4, the single rotary input is synchronously converted into the rotational motion of the rotating cover 2 and the linear motion of the lifting body 3. This integrated synchronous drive architecture fundamentally simplifies the system structure, significantly reduces the number of drive components, directly lowers manufacturing costs and overall weight, and makes the structural layout more compact. Since the rotational and linear motions originate from the same power source and are rigidly coupled through the mechanical structure, their motion phases, speeds, and positions always maintain a precise and predetermined correspondence, ensuring the coordination and consistency of complex actions such as the cup holder popping out while the cover opens, thus improving the user experience. Mechanical synchronous linkage avoids the complex electrical synchronization control programs and sensor feedback systems required when using multiple independent motors or actuators, simplifying the control logic, reducing the complexity and cost of the control system, and improving the system's response speed and reliability. Furthermore, this structure relies on mature gear and sliding pair transmissions, resulting in smooth motion, low noise, and easy achievement of the required output speed and torque through reasonable gear ratio design, exhibiting good engineering adaptability. The entire device has a clear power transmission path and a high degree of component integration, which is conducive to modular design and assembly, providing an efficient and reliable solution for achieving complex actions within the vehicle space.

[0054] When it is necessary to close the rotating cover and lower the lifting body, the motor 1 receives a reverse signal and rotates in the opposite direction. Its drive pin 42 slides in the reverse direction within the cover groove 21 of each rotating cover 2, thereby driving all rotating covers 2 to rotate synchronously in the opposite direction until they are closed. Simultaneously, the wall of the inclined groove 41 on the end face of the linkage gear 4 acts on the sliding pin 31 of the lifting body 3, pushing the lifting body 3 to retract along the guide portion 61 of the base 6, returning it to its initial position. Thus, the closing of the rotating cover and the lowering of the lifting body can be mechanically and synchronously achieved through a single reverse rotation command from the motor.

[0055] In this embodiment, the slide groove 41 is an inclined groove whose extending direction forms an angle with the radial direction of the linkage gear 4.

[0056] Specifically defining the slide groove 41 as an inclined groove provides an efficient and direct rotary-linear motion conversion mechanism. When the linkage gear 4 rotates, the inclined surface of the groove generates a continuous radial force relative to the sliding pin 31, thereby smoothly converting the circular motion of the gear into precise linear displacement of the sliding pin 31 and the connected lifting body 3. The inclination angle of the groove determines the proportional relationship between the linear motion stroke and the gear rotation angle. By designing a specific groove profile, the motion curve of the lifting body 3 can be easily customized, such as achieving rapid start-up and slow descent or specific speed changes to meet different functional and experiential requirements. This conversion method has a compact structure, direct power transmission, controllable friction, and relatively simple processing and manufacturing, which helps to ensure the smoothness and reliability of the motion.

[0057] In this embodiment, a transmission assembly 5 is also included. The transmission assembly 5 includes a worm gear 51 connected to the output shaft of the motor 1, an input gear 52 meshing with the worm gear 51, and a linkage gear 4 meshing with the input gear 52.

[0058] By introducing a transmission assembly 5 containing a worm gear 51 and an input gear 52, a highly efficient and self-locking speed-reducing torque-increasing transmission chain is constructed. The worm gear drive achieves a large single-stage reduction ratio, allowing the use of a compact motor with a higher speed and lower rated torque. After reduction, it outputs sufficient torque to overcome motion resistance, ensuring the powerful and reliable operation of the rotating cover 2 and the lifting body 3. More importantly, the reverse self-locking characteristic of the worm gear drive prevents the load from driving the gear system in reverse when the motor 1 is de-energized. This allows the rotating cover 2 and the lifting body 3 to remain stably in any desired position without accidental movement or falling due to external forces or vibrations, enhancing the safety and user experience of the device. This transmission structure is flexible in its arrangement, helping to optimize the overall spatial layout of the device.

[0059] In this embodiment, a base 6 is also included, on which a guide portion 61 is provided. The lifting body 3 moves in a straight line by sliding with the guide portion 61.

[0060] By setting an independent base 6 with a guide section 61, precise and stable constraints and support are provided for the linear movement of the lifting body 3. The guide section 61 ensures that the lifting body 3 moves strictly along the preset linear trajectory, preventing it from swaying, jamming, or derailing during movement, thus guaranteeing the accuracy and repeatability of the action. As a stable installation platform, the base 6 effectively isolates the moving parts from the vehicle-mounted installation structure, facilitating the modular installation and debugging of the entire device. It also helps to bear and disperse the loads and vibrations generated during movement, improving the overall rigidity and service life of the structure.

[0061] In this embodiment, a bracket 7 is also included, and the rotating cover 2 is rotatably mounted on the bracket 7 via a pivot shaft 71.

[0062] By setting up an independent bracket 7 and configuring a pivot shaft 71 for the rotating cover 2, the fixed rotation center of the rotating cover 2 is clearly defined, and its rotational trajectory is strictly limited. The bracket 7 provides a stable mounting base for the entire rotating mechanism, ensuring the smoothness and consistency of the rotating cover 2's rotation around the axis, and avoiding shaking or abnormal noise caused by unstable support. This split design facilitates the independent processing, assembly, and maintenance of components such as the rotating cover 2, bracket 7, and linkage gear 4, improving the convenience of production and after-sales service, while also enhancing the load-bearing capacity and durability of the entire rotating motion pair.

[0063] In this embodiment, there are multiple drive pins 42, and the number of cover grooves 21 is the same as the number of drive pins 42 and they correspond to each other.

[0064] By employing multiple drive pins 42 in conjunction with a corresponding number of cover grooves 21, the stress distribution and motion balance of the rotating cover 2 can be significantly improved. Multiple contact points can more evenly distribute the drive load, reducing stress concentration at the contact point between a single drive pin 42 and the groove, thereby reducing wear, extending service life, and allowing the driving of larger or heavier rotating covers 2. The symmetrically arranged multiple drive points can effectively balance the lateral forces experienced by the rotating cover 2 during movement, preventing jamming or uneven wear caused by the additional torque generated by single-point drive, ensuring smoother and more stable rotation, and improving the reliability and smoothness of the mechanism's operation.

[0065] In this embodiment, there are multiple rotating covers 2, and each rotating cover 2 is engaged with a drive pin 42 through a cover groove 21 on it.

[0066] This design enables a single linkage gear 4 to synchronously drive multiple rotating covers 2 in coordinated motion. This greatly expands the functionality of the device; for example, it can simultaneously control the opening and closing of multiple storage box covers or function panels arranged side by side, achieving complex multi-objective synchronous control with the most streamlined drive system. All driven rotating covers 2 strictly follow the rotational speed and phase of the same linkage gear 4, ensuring a high degree of synchronization and consistency in their actions. There is no need to set up a separate drive and synchronization control system for each cover, maximizing cost, space, and control complexity savings while achieving complex visual effects or functional layouts.

[0067] In this embodiment, the output shaft axis of motor 1, the rotation axis of linkage gear 4, and the linear motion direction of lifting body 3 are all perpendicular or approximately perpendicular to each other.

[0068] This spatially orthogonal or near-orthogonal layout makes full use of three-dimensional space, resulting in a very compact structure and minimized overall volume, making it particularly suitable for placement in space-constrained vehicle environments. The power transmission path is clear, with each direction of motion not interfering with the others, facilitating mechanical analysis and structural optimization. The vertical layout also facilitates the modular design and integration of the motor, gearbox, and actuator, which is beneficial for heat dissipation and wiring harness arrangement. The compact "three-dimensional vertical" configuration reduces the device's encroachment on surrounding space, providing greater flexibility for vehicle interior design and making it easier to integrate into the overall cabin layout.

[0069] In this embodiment, motor 1 is a drive motor that can receive electrical signals and reverse direction.

[0070] The use of a reversible drive motor 1 allows the entire device to control the rotating cover 2 and the lifting body 3 to complete a full cycle of "opening-extending" and "closing-retracting" actions via a simple polarity-switching electrical signal. This achieves precise bidirectional control of complex actions. The user or vehicle control system can command the device to complete a full cycle with a single control command (such as voltage direction), and the control interface is simple and reliable. This bidirectional drive capability is fundamental to automated reciprocating motion, meeting the application requirements of in-vehicle functional components such as hidden cup holders and smart storage boxes that require frequent state switching, thus enhancing the device's intelligence and practicality.

[0071] The motor 1 is preferably a reversible DC motor, which is fixedly mounted to the base 6 or a fixed structure of the vehicle by fasteners. The non-output end of the motor 1 is typically provided with a motor cover 11, which is mainly used for protection, dust prevention, and aesthetics, and is a conventional accessory component in this field. The transmission assembly 5 includes a worm gear 51 fixed to the output shaft of the motor 1, and an input gear 52 meshing with the worm gear 51. The input gear 52 directly meshes with the linkage gear 4, thereby transmitting the power of the motor 1 to the linkage gear 4. The linkage gear 4 is rotatably supported on a fixed gear slot bracket 62 by bearings or bushings. The gear slot bracket 62 can be directly formed on the base 6 or fixed to the base 6 as a separate component. The four drive pins 42 are preferably evenly distributed along the circumference of the linkage gear 4. Each rotating cover 2 is rotatably mounted on the bracket 7 via its respective pivot shaft 71. The pivot shafts 71 of the four rotating covers 2 are coaxially arranged in pairs, thereby realizing two sets of opening movements. Example 2

[0072] This embodiment provides a vehicle that integrates an on-board single-motor linkage device as described in any of the preceding embodiments.

[0073] Specifically, the on-board single-motor linkage device is arranged as a functional drive module in a specific location in the vehicle interior, such as the center console storage area, the front of the armrest box, or the rear air vent control panel. The rotating cover of this device forms a visible functional panel or cover, and its lifting body serves as a support platform linked to the cover, together forming a hidden cup holder, a pop-up storage box, or an outlet mechanism for an intelligent fragrance system.

[0074] In this vehicle, the base or bracket of the on-board single-motor linkage device is securely mounted to the vehicle body or interior frame. The device's control circuitry is electrically connected to the vehicle's body control module or a dedicated convenience function controller, allowing the user to send a start signal to the motor via physical buttons, touchscreen commands, or voice control.

[0075] When the user issues an opening command, the vehicle control system provides a drive signal with the correct polarity to the motor. The motor starts and drives the linkage gear to rotate via the transmission assembly. The simultaneous rotation of the linkage gear, through its drive pin engaging with the cover's sliding groove, smoothly opens the rotating cover; simultaneously, through its end face's sliding groove engaging with the sliding pin on the lifting body, it synchronously pushes the lifting body out linearly. The opening angle of the rotating cover and the lifting height of the lifting body are uniquely determined by the rotation angle of the linkage gear, and the two are mechanically strictly synchronized, achieving an integrated and continuous action of "cover opening - platform rising," resulting in a smooth and technologically advanced visual effect. When closing is required, the control system reverses the motor polarity, and the device executes the opposite synchronous action of "cover closing - platform lowering" until it returns to its initial hidden state.

[0076] By integrating the aforementioned onboard single-motor linkage device into the vehicle, a highly integrated single drive module can replace similar complex functions that traditionally require multiple independent drives and complex control systems. This significantly simplifies the internal structural layout of the corresponding functional areas of the vehicle, saves installation space, and reduces wiring harness complexity and overall cost. Simultaneously, the reliable synchronization and simplified control requirements brought about by the mechanical linkage of this device also improve the consistency of operational response and long-term reliability of the corresponding vehicle functions, providing passengers with a convenient and high-quality interior interaction experience.
