[0051] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0052] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0053] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0054] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0055] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0056] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0057] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0058] Figure 1 This is a schematic diagram of the tail fin system according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of a tail fin system according to one embodiment of the present disclosure from another angle.
[0059] like Figure 1 and Figure 2 As shown, the tail fin system disclosed herein may include components such as actuator 100, drive unit 200, and tail fin 300.
[0060] The actuator 100 disclosed herein is used to provide driving force. In one embodiment, the actuator 100 includes a motor and a gear driven by the motor; the gear is used to drive the flocked cable 110 to produce a displacement change. Preferably, two flocked cables 110 are provided, which can be arranged on both sides of the gear so that when the gear rotates, the flocked cables 110 can be driven to move at the same speed.
[0061] In one specific embodiment, the actuator 100 can use the structure in prior art CN116767360A. Based on this, the present disclosure will not make a detailed description of the structure of the actuator 100.
[0062] The driving device 200 is used to receive the driving force of the actuator 100 and generate movement; specifically, the flocking cable 110 is connected with the driving device 200, so that the driving device 200 generates linear movement through the pulling force of the flocking cable 110.
[0063] Figure 3 is a schematic diagram of the extended state of the driving device 200 according to one embodiment of the present disclosure. Figure 4 is a schematic diagram of the retracted state of the driving device 200 according to one embodiment of the present disclosure.
[0064] As shown in Figure 1 and Figure 2 The tail wing system of the present disclosure can further include a bottom plate 400 and a support frame 500; in actual use, the tail wing system of the present disclosure can be fixed by fixing the bottom plate 400 to the vehicle body of the vehicle. The support frame 500 of the present disclosure can be provided in two, and the two support frames 500 have the same structure, and the lower end of the support frame 500 is fixed to the bottom plate 400.
[0065] The two support frames 500 are arranged at different positions in the length direction of the tail wing 300. In one preferred embodiment, the two support frames 500 can be symmetrically arranged.
[0066] As shown in Figure 3 and Figure 4 The driving device 200 of the present disclosure is provided in the support frame 500, and the actuator 100 drives the driving device 200 to generate linear movement. Specifically, the driving device 200 of the present disclosure can include a housing 210 and a piston rod 220 slidably provided in the housing 210. The flocking cable 110 is connected with the piston rod 220, so that when the flocking cable 110 applies a pulling force to the piston rod 220, the piston rod 220 can slide relative to the housing 210 and move downward; in addition, the upward movement of the piston rod 220 can be achieved by the elastic force of the elastic component such as spring, of course, the upward movement of the piston rod 220 can also be driven by the flocking cable 110.
[0067] The housing 210 of the driving device 200 of the present disclosure is fixedly connected with the support frame 500 and is located inside the support frame 500, so that the driving device 200 of the present disclosure can be protected by the support frame 500, so that liquid such as rainwater cannot enter the driving device 200, so that the driving device 200 has a longer service life.
[0068] The driving device 200 is connected to the tail fin 300 through the linkage assembly 600, so that the tail fin 300 is in different postures through the movement of the driving device 200.
[0069] Specifically, when the driving device 200 is in the extended state, the tail fin 300 can be in the first posture, and at the same time, the tail fin 300 can provide the vehicle with the minimum downward pressure, that is, the first posture can be the initial state of the tail fin 300. When the driving device 200 is in the retracted state, the tail fin 300 can be in the second posture, that is, the maximum angle state, and at the same time, the tail fin can provide the vehicle with the maximum downward pressure. Of course, the driving device 200 can also be in a state between the extended state and the retracted state, and at this time, the tail fin 300 can be in a posture between the first posture and the second posture.
[0070] In the present disclosure, the tail fin 300 is hinged to the support frame 500 through a first hinge shaft 601; the tail fin 300 is hinged to the linkage assembly 600 through a second hinge shaft 602, wherein the first hinge shaft 601 and the second hinge shaft 602 are arranged in parallel. Moreover, when the tail fin system of the present disclosure is installed on the vehicle, the first hinge shaft 601 and the second hinge shaft 602 are both arranged horizontally and along the width direction of the vehicle; and moreover, the second hinge shaft 602 is located in front of the first hinge shaft 601.
[0071] Figure 5 is a structural schematic view of one state of the linkage assembly according to one embodiment of the present disclosure. Figure 6 is a structural schematic view of another state of the linkage assembly according to one embodiment of the present disclosure.
[0072] As shown in Figure 5 and Figure 6 , the linkage assembly 600 of the present disclosure includes components such as a first linkage 610, a second linkage 620, and a third linkage 630.
[0073] Among them, the driving device 200 of the present disclosure is arranged obliquely. When the tail fin system of the present disclosure is installed on the vehicle, in the direction from bottom to top, the driving device 200 is inclined backward, so that the included angle between the driving device 200 and the first linkage 610 of the present disclosure is obtuse; and when the driving device 200 of the present disclosure moves from the extended position to the retracted position, the included angle between the driving device 200 and the first linkage 610 gradually increases.
[0074] In the present disclosure, the upper end of the piston rod 220 is hinged to one end of the first connecting rod 610 through a third hinge shaft 603; the third hinge shaft 603 is also arranged horizontally.
[0075] The second connecting rod 620 is formed in a substantially triangular shape, wherein one corner of the second connecting rod 620 is hinged to the support frame 500 through a fourth hinge shaft 604; the other end of the first connecting rod 610 is hinged to the other corner of the second connecting rod 620 through a fifth hinge shaft 605.
[0076] The third connecting rod 630 is formed in an L-shaped member, one end of the third connecting rod 630 is hinged to the third corner of the second connecting rod 620 through a sixth hinge shaft 606, and the other end of the third connecting rod 630 is hinged to the tail fin 300 through the second hinge shaft 602.
[0077] In the tail fin system of the present disclosure, the first hinge shaft 601, the second hinge shaft 602, the third hinge shaft 603, the fourth hinge shaft 604, the fifth hinge shaft 605 and the sixth hinge shaft 606 are arranged parallel to each other.
[0078] Therefore, in the tail fin system of the present disclosure, when the driving device 200 is extended, the axes of the second hinge shaft 602, the fourth hinge shaft 604 and the sixth hinge shaft 606 are located in the same plane, and the sixth hinge shaft 606 is located between the second hinge shaft 602 and the fourth hinge shaft 604, thereby the connecting rod assembly 600 can be self-locked, at this time the tail fin can be stably maintained in the first posture (as shown in the Figure 5 Accordingly, the force applied by the gas to the tail fin cannot be transmitted to the actuator and the driving device, thereby reducing the control difficulty of the tail fin system.
[0079] When the driving device 200 is retracted, the axes of the second hinge shaft 602, the fourth hinge shaft 604 and the sixth hinge shaft 606 are located in the same plane, and the fourth hinge shaft 604 is located between the second hinge shaft 602 and the sixth hinge shaft 606. Therefore, the connecting rod assembly 600 can be self-locked, at this time the tail fin can be stably maintained in the second posture (as shown in the Figure 6 Accordingly, the force applied by the gas to the tail fin cannot be transmitted to the actuator and the driving device, thereby reducing the control difficulty of the tail fin system.
[0080] The driving device 200 and the connecting rod assembly 600 are arranged in two, each driving device 200 is connected to the tail fin 300 through a connecting rod assembly 600; the actuator 100 is used to drive the two driving devices 200 to move synchronously, thereby the tail fin system of the present disclosure can be stably maintained in each posture.
[0081] The tail wing system of the present disclosure further comprises a spoiler 700 fixed to the support frame 500 and located in front of the tail wing 300 to disturb the flowing gas through the spoiler 700, and the tail wing 300 is used to disturb the gas disturbed by the spoiler 700 again.
[0082] The tail wing system of the present disclosure drives the driving device through the flocked cable of the actuator, and then the driving device drives the tail wing to move through the linkage assembly, so that the vehicle has different depression forces; accordingly, the tail wing system of the present disclosure has a clever structure and is not prone to failure, that is, it has a long failure-free working time, and solves the technical problems proposed in the background art.
