Description

Spoiler control device, spoiler device and automobile

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 20, 2023, with application number 202311769015.X and application name “Spoiler Control Device, Spoiler Device and Automobile”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to, but are not limited to, the technical field of automobile parts, and in particular to a spoiler control device, a spoiler device, and an automobile. Background Art

[0003] Active spoilers in automobiles primarily optimize the vehicle's aerodynamic characteristics through adjustable components, enabling it to provide better stability and fuel economy under varying driving conditions. Currently, the primary transmission method for active spoilers in automobiles is to rotate an actuator to drive the drive rod of a multi-link mechanism, pushing the multi-link hinge to expand and retract. A less common transmission method involves rotating an actuator to drive a push-pull flexible shaft, which in turn pushes a sliding conduit to expand and retract. The former requires a dedicated actuator, resulting in a complex design, complex accessory connections, and high hinge quality requirements. The latter, on the other hand, requires a highly durable flocked push-pull flexible shaft and a matching high-strength metal flexible shaft conduit, resulting in low reliability.

Modes for Carrying Out the Invention

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. In the description of the present application, it should be understood that the terms "length", "upper", "lower", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0043] The relevant technical personnel of this application have noticed that the main transmission forms of the current active spoiler device of an automobile include a multi-link structure and a push-pull flexible shaft structure. In the multi-link structure, the actuator inputs the rotational motion to the driving rod of the multi-link mechanism to push the multi-link hinge to expand and retract. This structure requires the development of expensive dedicated actuators, and requires the design of hinges with complex structures and high weather resistance requirements when exposed to wet areas. Therefore, this structure is expensive and has a complex manufacturing process. In the push-pull flexible structure, the actuator inputs the rotational motion to the push-pull flexible shaft, and the flexible shaft pushes the sliding conduit to be pushed out and retracted. Although this structure can apply low-cost general actuators, it requires the use of high-durability flocked push-pull flexible shafts and matching high-strength metal flexible shaft conduits. The weight and cost are still high, and the durability of flocking still faces severe challenges in current applications.

[0044] In view of this, an embodiment of the present application provides a spoiler control device, which can not only further reduce costs but also has a simple manufacturing process and higher reliability.

[0045] The specific implementation of this application is described below through examples:

[0046] As shown in Figures 1 to 4, an embodiment of the present application provides a spoiler control device, comprising: a base support 100; a drive assembly 200 connected to the base support 100; a traction assembly 300 connected to the drive assembly 200; and a transmission assembly 400, wherein the transmission assembly 400 includes a guide seat 410 and a moving assembly 420, the guide seat 410 being connected to the base support 100; and the moving assembly 420 being movably disposed on the guide seat 410 and connected to the traction assembly 300. The drive assembly 200 is configured to pull the moving assembly 420 relative to the guide seat 410 via the traction assembly 300 to control the spoiler 700. Specifically, the base support 100 is used to support the drive assembly 200 and the transmission assembly 400, and is also used to connect to the vehicle body. The drive assembly 200 is a power source, generating traction through a motor or engine, thereby driving the traction assembly 300 to reciprocate. Driven by the drive assembly 200, the traction assembly 300 drives the mobile assembly 420 to reciprocate relative to the guide seat 410, thereby adjusting the angle of the spoiler 700. The spoiler 700 is connected to the mobile assembly 420. Through the cooperation of the drive assembly 200, the traction assembly 300, and the transmission assembly 400, effective control of the spoiler 700 is achieved. The movement mode of the spoiler 700 control device is simple and efficient, with high reliability, high maintenance efficiency, and easy maintenance.

[0047] As shown in FIG1 , in an embodiment of the present application, there are multiple transmission assemblies 400 , and the multiple transmission assemblies 400 are spaced apart. The multiple transmission assemblies 400 include a first transmission assembly 401 and a second transmission assembly 402 . The moving assembly 420 of the first transmission assembly 401 and the moving assembly 420 of the second transmission assembly 402 are connected to the same traction assembly 300 , and are used to move relative to the guide base 410 between a first position A and a second position B through the traction assembly 300 . Specifically, generally speaking, one transmission assembly 400 can control one spoiler 700 or control one side of the spoiler 700 . The more transmission assemblies 400 there are, the more spoilers 700 can be controlled, and the greater the range of adjustment of the spoiler 700 angle. Each transmission assembly 400 includes a guide base 410 and a moving assembly 420 . The guide base 410 includes an arc-shaped hollow pipe. The hollow design of the guide base 410 not only provides sufficient strength but also reduces weight. One end of the guide base 410 is connected to one side of the base bracket 100, and all guide bases 410 are connected to the same side of the base bracket 100. The moving assembly 420 is disposed on the guide base 410 and has a first position A and a second position B on the guide base 410. The moving assembly 420 can move back and forth between the first position A and the second position B under traction, thereby achieving control of the angle of the spoiler 700.

[0048] As shown in Figures 1 to 3, in the embodiment of the present application, the drive assembly 200 includes a rotating portion 210, and the traction assembly 300 is connected to the rotating portion 210. The rotating portion 210 rotates to drive the traction assembly 300 to move. When the rotating portion 210 rotates in a first rotational direction, the traction assembly 300 pulls the moving assembly 420 to move toward a first position A. When the rotating portion 210 rotates in a second rotational direction, the traction assembly 300 pulls the moving assembly 420 to move toward a second position B. The first rotational direction and the second rotational direction are opposite. It is understood that the rotating portion 210 can rotate in both a clockwise and counterclockwise direction, and different rotational directions will drive the traction assembly 300 to move in different directions. Therefore, when the rotating portion 210 rotates in a first rotational direction (clockwise), the traction assembly 300 moves along with the rotating portion 210, thereby driving the moving assembly 420 toward the first position A. Correspondingly, when the rotating portion 210 rotates in a second rotational direction (counterclockwise), the traction assembly 300 moves along with the rotating portion 210 in another direction, thereby driving the moving assembly 420 toward the second position B. Therefore, by rotating the rotating portion 210 in different directions, the movement direction of the moving assembly 420 can be controlled, thereby controlling the angle of the spoiler 700.

[0049] As shown in FIG1 , in the embodiment of the present application, the traction assembly 300 includes a first traction portion 310, a second traction portion 320, and a third traction portion 330. The first traction portion 310 is connected to the drive assembly 200 and the moving assembly 420 of the first transmission assembly 401. The second traction portion 320 is connected to the drive assembly 200 and the moving assembly 420 of the second transmission assembly 402. The third traction portion 330 connects the moving assembly 420 of the first transmission assembly 401 and the moving assembly 420 of the second transmission assembly 402. Specifically, the first traction portion 310 is used to pull the moving assembly 420 of the first transmission assembly 401 toward a first position A. Simultaneously, the moving assembly 420 drives the third traction portion 330 to pull the moving assembly 420 of the second transmission assembly 402 toward the first position A. The second traction portion 320 is used to pull the moving assembly 420 of the second transmission assembly 402 toward a second position B. Simultaneously, the moving assembly 420 drives the third traction portion 330 to pull the moving assembly 420 of the first transmission assembly 401 toward the second position B. Specifically, the traction assembly 300 consists of three sections: a first traction section 310, a second traction section 320, and a third traction section 330. One end of each of the first traction section 310 and the second traction section 320 is fixedly connected to the drive assembly 200. The first traction section 310 and the second traction section 320 extend in two directions. The other end of the first traction section 310 is fixedly connected to the moving assembly 420 on the first transmission assembly 401, while the other end of the second traction section 320 is fixedly connected to the moving assembly 420 on the second transmission assembly 402. The third traction section 330 connects the two moving assemblies 420. Thus, the first traction section 310, the second traction section 320, and the third traction section 330 form a traction loop.

[0050] It should be noted that the first pulling portion 310 is connected to the side of the moving assembly 420 closest to the base bracket 100, and the second pulling portion 320 is connected to the side of the moving assembly 420 further away from the base bracket 100. Because the first and second pulling portions 310, 320 extend in opposite directions, when the rotating portion 210 rotates in one direction, the first and second pulling portions 310, 320 are subjected to opposite pulling forces. When the rotating portion 210 rotates clockwise, the first pulling portion 310 is subjected to a pulling force toward the rotating portion 210, while the second pulling portion 320 is subjected to a pulling force away from the rotating portion 210 due to the combined pulling force of the third pulling portion 330. Therefore, when the rotating portion 210 rotates clockwise, the moving assembly 420 moves toward the first position A, and when the rotating portion 210 rotates counterclockwise, the moving assembly 420 moves toward the second position B.

[0051] It is worth noting that in some embodiments of the present application, the traction assembly 300 can also be an integral structure, that is, both ends of the traction assembly 300 are fixed to the rotating portion 210, and extend in two directions of the rotating portion 210 respectively, and the traction assembly 300 passes through the two moving assemblies 420 on the first transmission assembly 401 and the second transmission assembly 402. It should be noted that when the traction assembly 300 is an integral structure, the connection between the traction assembly 300 and the two moving assemblies 420 can be fixed. This can prevent the unfixed traction assembly 300 from sliding on the moving assembly 420 when the rotating portion 210 rotates, resulting in the inability to drive the moving assembly 420 to move to the first position A or the second position B.

[0052] It should be noted that the traction assembly 300 includes a rope structure, and the materials that can be selected include steel wire rope, nylon rope, carbon fiber rope and rope made of polymer material. The specific material can be selected according to the actual use scenario, and will not be described in detail here.

[0053] As shown in Figures 1 and 4, in the embodiment of the present application, the guide seat 410 has a guide channel 414 and a guide slit 411 connected to the guide channel 414. The moving assembly 420 includes a first moving portion 412, which is movably disposed in the guide channel 414; a second moving portion 413, which is movably disposed in the guide slit 411 and connected to the first moving portion 412 and the traction assembly 300. The traction assembly 300 pulls the second moving portion 413 along the guide slit 411 to move along the guide channel 414, thereby driving the first moving portion 412 to move along the guide channel 414. The first moving portion 412 moves to control the spoiler 700. Specifically, as described above, the guide seat 410 is an arc-shaped pipe, with the guide channel 414 inside the guide seat 410 and the guide slit 411 on the surface of the guide seat 410 connected to the guide channel 414. The moving assembly 420 comprises two parts: a first moving portion 412 and a second moving portion 413. The first moving portion 412 is slidably disposed within the guide channel 414, while the second moving portion 413 extends through the guide slit 411, with one end positioned outside the guide seat 410 and the other end positioned within the guide channel 414 and fixedly connected to the first moving portion 412. The traction assembly 300 is connected to both ends of the second moving portion 413. By rotating the rotating portion 210 in different directions, the traction assembly 300 can pull the second moving portion 413 in different directions. The second moving portion 413 then drives the first moving portion 412 to move back and forth within the guide channel 414, thereby controlling the spoiler 700.

[0054] As shown in Figures 1 to 3, in an embodiment of the present application, the drive assembly 200 further includes a drive unit 220, which is connected to the rotating unit 210; the traction assembly 300 is connected to the rotating unit 210; the rotating unit 210 includes a winding member 211 and a fixing member 212, the winding member 211 surrounds the fixing member 212, and the fixing member 212 is cooperatively connected to the drive unit 220. Specifically, the drive unit 220 is a power source capable of providing power, including a motor, an engine, etc., and the drive unit 220 drives the rotating unit 210 to rotate under the energy drive. For example, the drive unit 220 can be a linear motor or a servo motor, and the drive unit 220 includes an output shaft, and the fixing member 212 in the rotating unit 210 is fixedly connected to the output shaft of the drive unit 220. Under electric drive, the drive unit 220 rotates, thereby driving the rotating unit 210 to rotate together.

[0055] Optionally, in an embodiment of the present application, when the driving part 220 rotates, the rotating part 210 rotates therewith, and the traction component 300 is wound by the winding member 211, thereby shortening the size of the traction component 300 on one side, thereby pulling and moving the moving component 420, thereby controlling the spoiler 700.

[0056] As shown in Figures 1 to 3, in the embodiment of the present application, the rotating portion 210 is provided with a card interface 213, which is located between the winding member 211 and the fixing member 212. The winding member 211 is provided with a notch 214 extending along the card interface 213. The first traction portion 310 and / or the second traction portion 320 are provided with a card block 331, which cooperates with the card interface 213, and the first traction portion 310 and / or the second traction portion 320 are wound around the winding member 211 along the notch 214. Specifically, when the traction assembly 300 includes the first traction portion 310, the second traction portion 320, and the third traction portion 330, one end of the first traction portion 310 and the second traction portion 320 is provided with a card block 331, which is engaged with the card interface 213, and the first traction portion 310 and the second traction portion 320 are wound around the surface of the winding member 211 along the notch 214.

[0057] It should be noted that in the embodiment of the present application, in order to prevent the rotating portion 210 from simultaneously reeling in the first traction portion 310 and the second traction portion 320 during rotation, thereby causing the moving assembly 420 to excessively pull on the traction assembly 300, resulting in breakage or damage, during the initial stage of winding the first traction portion 310 and the second traction portion 320, the winding degrees of the first traction portion 310 and the second traction portion 320 can be precisely set, that is, when the first traction portion 310 is completely unwound, the second traction portion 320 is exactly in the reeling state. Therefore, by controlling the timing of reeling and unwinding and the length of the first traction portion 310 and the second traction portion 320, precise control of the spoiler 700 can be achieved.

[0058] As shown in FIG1 , in the embodiment of the present application, the transmission assembly 400 is provided with a pulley assembly 500, and the traction assembly 300 is disposed through the pulley assembly 500. The pulley assembly 500 is used to guide the traction assembly 300. Specifically, the pulley assembly 500 includes a first fixed pulley 510, a second fixed pulley 520, a third fixed pulley 530, and a fourth fixed pulley 540. The first fixed pulley 510 and the second fixed pulley 520 are fixedly disposed on the first transmission assembly 401 and are used to guide and limit the movement of the third traction unit 330 on the first transmission assembly 401. The third fixed pulley 530 and the fourth fixed pulley 540 are fixedly disposed on the second transmission assembly 402 and are used to guide and limit the movement of the second traction unit 320 on the second transmission assembly 402. It should be noted that the pulley assembly 500 may have more or fewer pulleys depending on the traction direction of the traction assembly 300. The specific number of pulleys can be selected based on actual conditions, and the embodiment of the present application will not be listed in detail here.

[0059] As shown in Figure 1, in this embodiment of the present application, a limiting tube 600 is sleeved over at least a portion of the structure of the traction assembly 300. The limiting tube 600 is used to limit the movement trajectory of the traction assembly 300. Specifically, the traction assembly 300 is a rope structure and cannot independently form a specific trajectory on the base bracket 100. To prevent the traction assembly 300 from abrading other components during movement, thereby causing damage to the circuit or devices, at least a portion of the structure or the entire structure of the traction assembly 300 is sleeved over the limiting tube 600. Encasing the traction assembly 300 with the limiting tube 600 not only protects the traction assembly 300 but also, if the limiting tube 600 is strong enough, can fix the trajectory of the traction assembly 300.

[0060] It is worth noting that the space between the first transmission assembly 401 and the second transmission assembly 402 is required to connect other components. Therefore, when the traction assembly 300 includes the second traction part 320, the second traction part 320 is fixed by being sleeved with the limiting tube 600, so that the second traction part 320 can be close to the bottom bracket 100, leaving sufficient space for the installation of other components.
