Therefore, the number of parts is small, the assembly is simple, and the motor alone has no protruding output shaft, which can reduce its occupied volume.
根据本发明的一个实施例,驱动机构包括两个连杆组件,分别设置在驱动轴的两端,通过将其中一个连杆组件或两个连杆组件的第二连杆设置成可沿其长度方向伸缩,就可以调节扰流板的位置、角度,从而改变扰流板的姿态,使得扰流板能够准确地调整至设定位置。According to one embodiment of the present invention, the driving mechanism includes two connecting rod assemblies, which are respectively arranged at both ends of the driving shaft. By arranging one of the connecting rod assemblies or the second connecting rod of the two connecting rod assemblies to be retractable along their length direction, the position and angle of the spoiler can be adjusted, thereby changing the posture of the spoiler, so that the spoiler can be accurately adjusted to the set position.
根据本发明的一个实施例,通过沿驱动轴的轴向布置多个连杆组件可以更好地驱动扰流板,使得扰流板受力更均衡,转动时更稳定。According to one embodiment of the present invention, the spoiler can be better driven by arranging a plurality of connecting rod assemblies along the axial direction of the driving shaft, so that the spoiler is subjected to a more balanced force and is more stable when rotating.
根据本发明的一个实施例,通过在底板处巧妙地设置限位凸起,利用限位凸起的两个限位面来限定第一连杆的转动极限位置,而不用单独地设置专门的限位机构,因此简化了结构。According to an embodiment of the present invention, a limiting protrusion is cleverly provided on the bottom plate, and two limiting surfaces of the limiting protrusion are used to limit the rotation limit position of the first connecting rod without separately providing a special limiting mechanism, thereby simplifying the structure.
进一步地,通过检测电机的电流,并在堵转时电流大于预设值的特点来通过电机控制器控制电机停机,这样就不需要专门设置用于检测连杆组件是否到达极限位置的传感器,因此控制过程较为简单,采用的部件数量较少,成本低且易实现。Furthermore, by detecting the current of the motor and controlling the motor to stop through the motor controller when the current is greater than a preset value when the motor is stalled, there is no need to specially set up a sensor for detecting whether the connecting rod assembly has reached the limit position. Therefore, the control process is relatively simple, the number of components used is small, the cost is low and it is easy to implement.

FIG. 2 is a schematic diagram of the exploded structure of the diffuser system 100 and the vehicle body according to an embodiment of the present invention. FIG. 3 is a schematic diagram of the structure of the diffuser system 100 when the spoiler 22 is in the first position according to an embodiment of the present invention. FIG. 4 is a schematic diagram of the structure of the diffuser system 100 when the spoiler 22 is in the second position according to an embodiment of the present invention. FIG. 5 is a schematic diagram of the airflow when the spoiler 22 of the diffuser system 100 is in the second position according to an embodiment of the present invention. FIG. 6 is a schematic diagram of the airflow when the spoiler 22 of the diffuser system 100 is in the first position according to an embodiment of the present invention. The solid lines in FIG. 5 and FIG. 6 represent the bottom of the vehicle, and the dotted arrows are the airflow directions. The present invention provides a diffuser system 100 (also referred to as an air guide system) for a vehicle, as shown in FIG. 1. In one embodiment, the diffuser system 100 includes a support plate 10 and a diffuser device 20. As shown in FIG2 , the support plate 10 is used to be installed at the bottom of the vehicle, and the support plate 10 is provided with at least one opening 101. For example, the support plate 10 is a part of the rear bumper bottom guard plate, and can also be a plate member installed at the rear bumper bottom guard plate at the rear end of the vehicle. The diffuser device 20 includes a driving mechanism 21 and at least one spoiler 22. The driving mechanism 21 is arranged at the support plate 10. The spoiler 22 is arranged at the opening 101 and is connected to the driving mechanism 21. The driving mechanism 21 is used to drive the spoiler 22 to rotate relative to the support plate 10. The driving mechanism 21 is arranged to drive the spoiler 22 to rotate to a first position. When the spoiler 22 is in the first position (see FIG3 ), the spoiler 22 opens the opening 101. The driving mechanism 21 is arranged to drive the spoiler 22 to rotate to a second position (see FIG4 ). When the spoiler 22 is in the second position, the spoiler 22 closes the opening 101. In one embodiment, the spoiler 22 can also stay at any position between the first position and the second position, which is not limited here.
本实施例通过在车辆的底部通过带开口101的支撑板10安装扩散器装置20,该扩散器装置20包括可通过驱动机构21驱动的扰流板22,使得扰流板22能够关闭或打开支撑板10处的开口101。在扰流板22打开开口101时,一方面可以减弱或消除扩散器装置20后方的湍流(图5中的A为湍流),从而降低整车的空气阻力;另一方面在扰流板22打开开口101时(参见图6),扰流板22下方的气流流速大于扰流板22上方的气流流速,从而能够对整车提供下压力。综上,通过本实施例提供的扩散器装置,能够在不过多地增加整车阻力的前提下达到增加车辆下压力的效果,甚至能够达到减小整车阻力的同时提升整车下压力的效果。In this embodiment, a diffuser device 20 is installed at the bottom of the vehicle through a support plate 10 with an opening 101. The diffuser device 20 includes a spoiler 22 that can be driven by a driving mechanism 21, so that the spoiler 22 can close or open the opening 101 at the support plate 10. When the spoiler 22 opens the opening 101, on the one hand, the turbulence behind the diffuser device 20 (A in FIG. 5 is turbulence) can be weakened or eliminated, thereby reducing the air resistance of the entire vehicle; on the other hand, when the spoiler 22 opens the opening 101 (see FIG. 6), the air flow velocity below the spoiler 22 is greater than the air flow velocity above the spoiler 22, thereby providing downforce to the entire vehicle. In summary, through the diffuser device provided in this embodiment, the effect of increasing the downforce of the vehicle can be achieved without increasing the resistance of the entire vehicle too much, and even the effect of reducing the resistance of the entire vehicle while increasing the downforce of the entire vehicle can be achieved.
如图2所示,进一步的一个实施例中,扩散器系统100还包括安装支架30,安装支架30固定于支撑板10上,扩散器装置20固定在安装支架30上。一个实施例中,安装支架30环绕开口101设置,如图2中的环形件。As shown in Fig. 2, in a further embodiment, the diffuser system 100 further comprises a mounting bracket 30, the mounting bracket 30 is fixed on the support plate 10, and the diffuser device 20 is fixed on the mounting bracket 30. In one embodiment, the mounting bracket 30 is arranged around the opening 101, such as a ring member in Fig. 2.
由于上述的支撑板10可以是后保险杠底护板的一部分,也可以是安装在车辆后端的后保险杠底护板处的一个板件,考虑到后保险杠的外观美观性及其空气动力学性能,其外表面一般设置为平整表面,而由于支撑板10的工艺要求,较难直接在支撑板10内表面设置用于安装扩散器装置20的结构。因此通过设置安装支架30,先将安装支架30固定于支撑板10上,安装支架30上可以设置用于安装扩散器装置20的结构,既能够保证支撑板10的外观面的要求,同时又能够实现对扩散器装置20的可靠安装。在一实施例中,将安装支架30设置成环形件,可以粘结到支撑板10的靠近车内的一侧,然后安装支架30远离支撑板10的一侧再通过卡接等当时与扩散器装置20相连,使得用于扩散器装置20以及相应的连接结构均位于后保险杠靠近车内的一侧,以保证后保险杠的外观美观性。Since the support plate 10 can be a part of the rear bumper bottom guard plate, or a plate installed at the rear bumper bottom guard plate at the rear end of the vehicle, considering the appearance and aerodynamic performance of the rear bumper, its outer surface is generally set to a flat surface, and due to the process requirements of the support plate 10, it is difficult to directly set the structure for installing the diffuser device 20 on the inner surface of the support plate 10. Therefore, by setting the mounting bracket 30, the mounting bracket 30 is first fixed on the support plate 10, and the mounting bracket 30 can be set with a structure for installing the diffuser device 20, which can not only ensure the appearance requirements of the support plate 10, but also achieve reliable installation of the diffuser device 20. In one embodiment, the mounting bracket 30 is set as a ring member, which can be bonded to the side of the support plate 10 close to the interior of the vehicle, and then the side of the mounting bracket 30 away from the support plate 10 is connected to the diffuser device 20 by clamping, etc., so that the diffuser device 20 and the corresponding connection structure are both located on the side of the rear bumper close to the interior of the vehicle, so as to ensure the appearance of the rear bumper.
图7是根据本发明一个实施例的扩散器系统100的驱动机构21与扰流板22的装配结构示意图。如图7所示,一个实施例中,驱动机构21包括电机211、驱动轴212和至少一连杆组件213,图7以设置两个连杆组件213为例。可以理解的是,在其他实施例中,连杆组件213的数量也可以为1个、3个或3个以上。电机211用于输出转矩。驱动轴212与电机211的转子相连。FIG7 is a schematic diagram of the assembly structure of the drive mechanism 21 and the spoiler 22 of the diffuser system 100 according to an embodiment of the present invention. As shown in FIG7, in one embodiment, the drive mechanism 21 includes a motor 211, a drive shaft 212 and at least one connecting rod assembly 213, and FIG7 takes two connecting rod assemblies 213 as an example. It can be understood that in other embodiments, the number of connecting rod assemblies 213 can also be 1, 3 or more than 3. The motor 211 is used to output torque. The drive shaft 212 is connected to the rotor of the motor 211.
连杆组件213的固定端2131与驱动轴212固定连接,驱动轴212驱动连杆组件213的固定端2131转动。连杆组件213的自由端2132与扰流板22的自由端铰接,在驱动轴212的驱动下,连杆组件213带动扰流板22转动。The fixed end 2131 of the connecting rod assembly 213 is fixedly connected to the driving shaft 212, and the driving shaft 212 drives the fixed end 2131 of the connecting rod assembly 213 to rotate. The free end 2132 of the connecting rod assembly 213 is hinged to the free end of the spoiler 22, and under the drive of the driving shaft 212, the connecting rod assembly 213 drives the spoiler 22 to rotate.
一个实施例中,连杆组件213的至少一部分长度可调节。在驱动轴212转动至第一转动位置时(即驱动轴212转动一定角度时),通过调节该连杆组件213的至少一部分的长度,连杆组件213的自由端可在第一位置范围内调节,连杆组件213的自由端可分别调节并固定于至少第一调节位置和第二调节位置,第一调节位置和第二调节位置位于第一位置范围内。In one embodiment, at least a portion of the length of the connecting rod assembly 213 is adjustable. When the drive shaft 212 rotates to the first rotation position (i.e., when the drive shaft 212 rotates a certain angle), by adjusting the length of at least a portion of the connecting rod assembly 213, the free end of the connecting rod assembly 213 can be adjusted within the first position range, and the free end of the connecting rod assembly 213 can be adjusted and fixed to at least the first adjustment position and the second adjustment position, respectively, and the first adjustment position and the second adjustment position are located within the first position range.
本实施例通过将连杆组件213的至少一部分设置成长度可调,因此能够在驱动轴212转动至第一转动位置时,连杆组件213的自由端的位置可以调节,进而调节扰流板22的打开角度和姿态,以使得扰流板22的调节更灵活。In this embodiment, by arranging at least a portion of the connecting rod assembly 213 to be adjustable in length, the position of the free end of the connecting rod assembly 213 can be adjusted when the drive shaft 212 is rotated to the first rotation position, thereby adjusting the opening angle and posture of the spoiler 22, so that the adjustment of the spoiler 22 is more flexible.
一个实施例中,电机211的转子固连电机211的输出轴,电机211输出轴再与驱动轴212相连,例如通过联轴器等常用的轴连接方式。In one embodiment, the rotor of the motor 211 is fixedly connected to the output shaft of the motor 211 , and the output shaft of the motor 211 is further connected to the drive shaft 212 , for example, through a common shaft connection method such as a coupling.
图8是根据本发明一个实施例的扩散器系统100的电机211和驱动轴212的分解示意图。如图8所示,一个实施例中,电机211的转子设有安装孔201,驱动轴212穿设于安装孔201内且二者通过花键形成防转动连接。例如,转子的安装孔201内设有多条沿轴向延伸且凹陷的凹槽202,驱动轴212插入安装孔201内的部分的外表面设有与各个凹槽202匹配的筋条203,使得电机211的转子和驱动轴212形成防转动连接。FIG8 is an exploded schematic diagram of a motor 211 and a drive shaft 212 of a diffuser system 100 according to an embodiment of the present invention. As shown in FIG8, in one embodiment, the rotor of the motor 211 is provided with a mounting hole 201, the drive shaft 212 is inserted into the mounting hole 201, and the two are connected to each other in an anti-rotation manner through a spline. For example, a plurality of grooves 202 extending in the axial direction and concave are provided in the mounting hole 201 of the rotor, and a rib 203 matching each groove 202 is provided on the outer surface of the portion of the drive shaft 212 inserted into the mounting hole 201, so that the rotor of the motor 211 and the drive shaft 212 form an anti-rotation connection.
本实施例的电机211的转子设有安装孔201,用于插入部分的驱动轴212并与驱动轴212通过花键连接,因此省去了联轴器等轴连接部件,因此零件数量少,装配简单,且电机211单独没有突出的输出轴,可以减小其占用体积。The rotor of the motor 211 of this embodiment is provided with a mounting hole 201 for inserting part of the drive shaft 212 and being connected to the drive shaft 212 by a spline, thereby eliminating shaft connection components such as couplings. Therefore, the number of parts is small and the assembly is simple. In addition, the motor 211 alone does not have a protruding output shaft, which can reduce its occupied volume.
如图7所示,一个实施例中,连杆组件213包括第一连杆214和第二连杆215。第一连杆214的固定端与驱动轴212固定连接,第一连杆214的自由端与第二连杆215的一端铰接,第二连杆的另一端(即自由端)与扰流板22的自由端222铰接。扰流板22的铰接端221与扩散器装置20的固定部件铰接。As shown in FIG7 , in one embodiment, the connecting rod assembly 213 includes a first connecting rod 214 and a second connecting rod 215. The fixed end of the first connecting rod 214 is fixedly connected to the drive shaft 212, the free end of the first connecting rod 214 is hinged to one end of the second connecting rod 215, and the other end (i.e., the free end) of the second connecting rod is hinged to the free end 222 of the spoiler 22. The hinged end 221 of the spoiler 22 is hinged to the fixed component of the diffuser device 20.
本实施例中通过电机211驱动驱动轴212转动,驱动轴212带动第一连杆214和第二连杆215,进而带动扰流板22绕其铰接端转动,从而控制扰流板22的开启角度。In this embodiment, the motor 211 drives the drive shaft 212 to rotate, and the drive shaft 212 drives the first connecting rod 214 and the second connecting rod 215, thereby driving the spoiler 22 to rotate around its hinge end, so as to control the opening angle of the spoiler 22.
一个实施例中,第二连杆215设置成可沿其长度方向伸缩的部件,以便通过该调节驱动机构21的第二连杆215来更加精确的调节扰流板22的姿态。In one embodiment, the second connecting rod 215 is configured as a component that can be extended and retracted along its length direction, so that the posture of the spoiler 22 can be more accurately adjusted by adjusting the second connecting rod 215 of the driving mechanism 21 .
如图7中,一个实施例中,驱动机构21包括两个连杆组件213,分别连接于扰流板22的自由端的两侧。通过将其中一个连杆组件213或两个连杆组件213的第二连杆215设置成可沿其长度方向伸缩,就可以调节扰流板22的位置、角度,从而改变扰流板22的姿态,使得扰流板22能够准确地调整至设定位置。例如,在扰流板22转动至第一位置时,可以对两个连杆组件213的长度进行微调,进而使得扰流板22的姿态或角度更加满足要求,更加满足于对风阻和下压力的要求。同样的,在扰流板22转动至第二位置时,可以对两个连杆组件213的长度进行微调,使得扰流板22在开口内的位置更加符合要求,更加满足于对车辆外观面、风阻和下压力的要求。As shown in FIG. 7 , in one embodiment, the driving mechanism 21 includes two connecting rod assemblies 213, which are respectively connected to both sides of the free end of the spoiler 22. By setting the second connecting rod 215 of one of the connecting rod assemblies 213 or the two connecting rod assemblies 213 to be retractable along its length direction, the position and angle of the spoiler 22 can be adjusted, thereby changing the posture of the spoiler 22, so that the spoiler 22 can be accurately adjusted to the set position. For example, when the spoiler 22 rotates to the first position, the length of the two connecting rod assemblies 213 can be fine-tuned, so that the posture or angle of the spoiler 22 can be more satisfactory, and the requirements for wind resistance and downforce can be more satisfied. Similarly, when the spoiler 22 rotates to the second position, the length of the two connecting rod assemblies 213 can be fine-tuned, so that the position of the spoiler 22 in the opening can be more satisfactory, and the requirements for the vehicle appearance, wind resistance and downforce can be more satisfied.
在一个实施例中,两个连杆组件213分别设置在驱动轴212的两端,通过一个驱动轴212来带动两个连杆组件213运动,这样能够节省驱动轴212的数量并且保证两个连杆组件213的运动的同步性。In one embodiment, two connecting rod assemblies 213 are respectively disposed at both ends of the driving shaft 212 , and one driving shaft 212 is used to drive the two connecting rod assemblies 213 to move, which can save the number of driving shafts 212 and ensure the synchronization of the movement of the two connecting rod assemblies 213 .
另一个实施例中,驱动轴212的数量可以是两个,分别伸出于电机211的两侧且均由该电机211驱动,一个驱动轴212上至少连接有一个连杆组件。这样可以将电机211布置在中间位置,使得重量分布更均衡,也能缩短每根驱动轴212的长度,方便制造。In another embodiment, there can be two drive shafts 212, which extend from both sides of the motor 211 and are driven by the motor 211, and at least one connecting rod assembly is connected to each drive shaft 212. In this way, the motor 211 can be arranged in the middle position, so that the weight distribution is more balanced, and the length of each drive shaft 212 can be shortened, which is convenient for manufacturing.
图9是根据本发明一个实施例的扩散器系统100的扰流板22与连杆组件213连接处的局部放大图。图10是根据本发明一个实施例的扩散器系统100的销轴41的结构示意图。如图9所示,一个实施例中,扩散器装置20还包括第一连接轴,扰流板22和第二连杆215通过第一连接轴相连,第一连接轴包括销轴41和卡簧42,销轴41的一端设有沿其径向凸起的帽部411,销轴41穿过扰流板22和第二连杆215后的另一端卡接有卡簧42。可以在该销轴41远离帽部的一端的周面处设置环形凹槽412(参见图10),用于与卡簧42卡接。FIG9 is a partial enlarged view of the connection between the spoiler 22 and the connecting rod assembly 213 of the diffuser system 100 according to an embodiment of the present invention. FIG10 is a schematic diagram of the structure of the pin 41 of the diffuser system 100 according to an embodiment of the present invention. As shown in FIG9, in one embodiment, the diffuser device 20 further includes a first connecting shaft, and the spoiler 22 and the second connecting rod 215 are connected through the first connecting shaft. The first connecting shaft includes a pin 41 and a retaining spring 42. One end of the pin 41 is provided with a cap 411 protruding along its radial direction, and the other end of the pin 41 after passing through the spoiler 22 and the second connecting rod 215 is clamped with the retaining spring 42. An annular groove 412 (see FIG10) can be provided on the circumferential surface of the end of the pin 41 away from the cap, for clamping with the retaining spring 42.
本实施例中通过销轴41和卡簧42连接扰流板22和第二连杆215的方式可以简化装配过程。In this embodiment, the spoiler 22 and the second connecting rod 215 are connected by the pin 41 and the retaining spring 42 to simplify the assembly process.
另一个实施例中,扩散器装置20还包括第二连接轴,扰流板22和第二连杆215通过第二连接轴相连,第二连接轴包括螺纹配合的螺栓和轴套,轴套穿过扰流板22和第二连杆215后与螺栓拧紧。当然,轴套的一端也要设置沿径向凸起的帽部。In another embodiment, the diffuser device 20 further includes a second connecting shaft, the spoiler 22 and the second connecting rod 215 are connected via the second connecting shaft, the second connecting shaft includes a bolt and a sleeve with threaded fit, the sleeve passes through the spoiler 22 and the second connecting rod 215 and is tightened with the bolt. Of course, a cap portion protruding in the radial direction is also provided at one end of the sleeve.
如图7所示,一个实施例中,驱动机构21包括至少两个沿驱动轴212的轴向间隔布置的连杆组件213,第二连杆215分别与扰流板22的可自由旋转的两端铰接。As shown in FIG. 7 , in one embodiment, the driving mechanism 21 includes at least two connecting rod assemblies 213 spaced apart along the axial direction of the driving shaft 212 , and the second connecting rod 215 is respectively hinged to two freely rotatable ends of the spoiler 22 .
本实施例通过沿驱动轴212的轴向布置多个连杆组件213可以更好地驱动扰流板22,使得扰流板22受力更均衡,转动时更稳定。In this embodiment, a plurality of connecting rod assemblies 213 are arranged along the axial direction of the driving shaft 212 to better drive the spoiler 22, so that the force on the spoiler 22 is more balanced and the rotation is more stable.
图11是根据本发明一个实施例的扩散器系统100的扩散器装置20的分解结构示意图。一个实施例中,如图11所示,扩散器装置20还包括底板23和盖板24。底板23用于安装电机211和驱动轴212。盖板24与底板23相连且共同限定出用于容纳电机211、驱动轴212和部分连杆组件213的空间(参见图1)。底板23和盖板24可以通过紧固件固定连接,然后与安装支架30固定连接,扰流板22可以与底板23铰接(例如图7中的铰接轴27),或者,扰流板22也可以与美化板25铰接。FIG11 is a schematic diagram of the exploded structure of the diffuser device 20 of the diffuser system 100 according to an embodiment of the present invention. In one embodiment, as shown in FIG11 , the diffuser device 20 further includes a base plate 23 and a cover plate 24. The base plate 23 is used to install the motor 211 and the drive shaft 212. The cover plate 24 is connected to the base plate 23 and together defines a space for accommodating the motor 211, the drive shaft 212 and a portion of the connecting rod assembly 213 (see FIG1 ). The base plate 23 and the cover plate 24 can be fixedly connected by fasteners and then fixedly connected to the mounting bracket 30, and the spoiler 22 can be hinged to the base plate 23 (such as the hinge shaft 27 in FIG7 ), or the spoiler 22 can also be hinged to the beautification plate 25.
图12是根据本发明一个实施例的扩散器系统100的在限位凸起231处的结构示意图。如图11所示,一个实施例中,底板23设有限位凸起231,如图12所示,限位凸起231上设有第一限位面232,用于在扰流板22转动至第一位置时与第一连杆214抵接,并在第一限位面232和第一连杆214抵接时使得电机211断电。限位凸起231上还设有第二限位面233,用于在扰流板22转动至第二位置时与第一连杆214抵接,并在第二限位面233和第一连杆214抵接时使得电机211断电。一个实施例中,可以通过力传感器来监测第一连杆214的受力,当其受到压力时,说明与第一限位面232或第二限位面233抵接,此时就可以控制电机211断电。另一个实施例中,扩散器系统100还包括电机211控制器,电机211控制器用于监测电机211的电流,第一连杆214与第一限位面232或第二限位面233抵接时,电机211堵转使得电流大于预设值,电机211控制器用于在电流大于预设值时控制电机211停机。FIG. 12 is a schematic diagram of the structure of the diffuser system 100 at the limiting protrusion 231 according to an embodiment of the present invention. As shown in FIG. 11 , in one embodiment, the bottom plate 23 is provided with a limiting protrusion 231. As shown in FIG. 12 , the limiting protrusion 231 is provided with a first limiting surface 232, which is used to abut against the first connecting rod 214 when the spoiler 22 rotates to the first position, and the motor 211 is powered off when the first limiting surface 232 and the first connecting rod 214 abut. The limiting protrusion 231 is also provided with a second limiting surface 233, which is used to abut against the first connecting rod 214 when the spoiler 22 rotates to the second position, and the motor 211 is powered off when the second limiting surface 233 and the first connecting rod 214 abut. In one embodiment, the force on the first connecting rod 214 can be monitored by a force sensor. When it is subjected to pressure, it means that it abuts against the first limiting surface 232 or the second limiting surface 233, and the motor 211 can be controlled to be powered off. In another embodiment, the diffuser system 100 also includes a motor 211 controller, which is used to monitor the current of the motor 211. When the first connecting rod 214 abuts against the first limit surface 232 or the second limit surface 233, the motor 211 is blocked so that the current is greater than a preset value. The motor 211 controller is used to control the motor 211 to stop when the current is greater than the preset value.
本实施例通过在底板23处巧妙地设置限位凸起231,利用限位凸起231的两个限位面来限定第一连杆214的转动极限位置,而不用单独地设置专门的限位机构,因此简化了结构。In this embodiment, a limiting protrusion 231 is cleverly provided on the bottom plate 23 , and two limiting surfaces of the limiting protrusion 231 are used to limit the rotation limit position of the first connecting rod 214 , without separately providing a special limiting mechanism, thereby simplifying the structure.
进一步地,通过检测电机211的电流,并在堵转时电流大于预设值的特点来通过电机211控制器控制电机211停机,这样就不需要专门设置用于检测连杆组件213是否到达极限位置的传感器,因此控制过程较为简单,采用的部件数量较少,成本低且易实现。Furthermore, by detecting the current of the motor 211 and the characteristic that the current is greater than a preset value when the motor is stalled, the motor 211 is controlled to stop through the motor 211 controller. In this way, there is no need to specially set up a sensor for detecting whether the connecting rod assembly 213 has reached the extreme position. Therefore, the control process is relatively simple, the number of components used is relatively small, the cost is low and it is easy to implement.
如图11所示,一个实施例中,扩散器装置20还包括美化板25,固定连接于底板23远离盖板24的一侧。美化板25可以设有多个凸起的卡扣251,卡接在底板23上卡扣孔234内,美化板25背向盖板24的一侧设置为平整的平面,以使得扰流板22打开后露出平整的表面。As shown in FIG. 11 , in one embodiment, the diffuser device 20 further includes a beautifying plate 25, which is fixedly connected to a side of the bottom plate 23 away from the cover plate 24. The beautifying plate 25 may be provided with a plurality of protruding buckles 251, which are snapped into the buckle holes 234 on the bottom plate 23, and a side of the beautifying plate 25 facing away from the cover plate 24 is set as a flat plane, so that the spoiler 22 is opened to expose a flat surface.
由于底板23上设有许多功能特征,例如用于放置驱动轴212、电机211的限位特征,穿设电线的条形槽等,因此底板23的正反面都会形成凹凸的形状,本实施例通过在底板23的底面处设置美化板25,可以遮挡底板23的特征,在扰流板22打开后仍然是平整表面,从而起到美化的作用,同时起到不影响车辆的空气动力学性能的作用。Since the bottom plate 23 is provided with many functional features, such as the limiting features for placing the drive shaft 212 and the motor 211, the strip grooves for passing the wires, etc., the front and back surfaces of the bottom plate 23 will form a concave and convex shape. In this embodiment, a beautification plate 25 is provided on the bottom surface of the bottom plate 23 to cover the features of the bottom plate 23. After the spoiler 22 is opened, it is still a flat surface, thereby playing a beautification role, and at the same time does not affect the aerodynamic performance of the vehicle.
图13是根据本发明一个实施例的扩散器系统100的美化板25的结构示意图。如图13所示,进一步的一个实施例中,美化板25面向扰流板22一侧还设有用于容纳扰流板22的容纳槽252,以便在扰流板22不打开时共同形成一个平面,提高结构的整体外观美观性。Fig. 13 is a schematic diagram of the structure of the beautification plate 25 of the diffuser system 100 according to an embodiment of the present invention. As shown in Fig. 13, in a further embodiment, the beautification plate 25 is further provided with a receiving groove 252 for receiving the spoiler 22 on the side facing the spoiler 22, so as to form a plane together when the spoiler 22 is not opened, thereby improving the overall appearance of the structure.
进一步地,由于驱动机构21和扰流板22是位于美化板25的两侧的,而驱动机构21和扰流板22之间存在铰接连接点,因此美化板25上还设有开孔253,用于穿过驱动机构21和扰流板22之间的铰接连接结构。Furthermore, since the driving mechanism 21 and the spoiler 22 are located on both sides of the beautification plate 25, and there is a hinge connection point between the driving mechanism 21 and the spoiler 22, an opening 253 is also provided on the beautification plate 25 for passing through the hinge connection structure between the driving mechanism 21 and the spoiler 22.
如图11所示,一个实施例中,扰流板22包括粘结的上扰流片221和下扰流片222。As shown in FIG. 11 , in one embodiment, the spoiler 22 includes an upper spoiler piece 221 and a lower spoiler piece 222 that are bonded together.
本实施例的扰流板22包括上扰流片221和下扰流片222,因此结构强度更高。The spoiler 22 of this embodiment includes an upper spoiler piece 221 and a lower spoiler piece 222 , and thus has a higher structural strength.
进一步的一个实施例中,上扰流片221和下扰流片222之间的中部形成有空腔、周缘部通过黏胶223粘结,如图11所示,该黏胶223呈环状。In a further embodiment, a cavity is formed in the middle between the upper spoiler 221 and the lower spoiler 222, and the peripheral portions are bonded by adhesive 223, as shown in FIG. 11, and the adhesive 223 is ring-shaped.
本实施例将上扰流片221和下扰流片222的中部设置成空腔结构,能够进一步提高扰流板22的强度,另外,只在上扰流片221和下扰流片222的周缘处粘结黏胶223可以降低其加工难度,只需要将上扰流片221的底部的周缘和下扰流片222的顶部的周缘加工呈平面以便于有效贴合粘结即可。In this embodiment, the middle parts of the upper spoiler 221 and the lower spoiler 222 are arranged as a cavity structure, which can further improve the strength of the spoiler 22. In addition, the adhesive 223 is only bonded to the periphery of the upper spoiler 221 and the lower spoiler 222 to reduce the processing difficulty. It is only necessary to process the periphery of the bottom of the upper spoiler 221 and the periphery of the top of the lower spoiler 222 into a plane for effective bonding.
一个实施例中,扰流板22打开开口101时其自身的最低点不低于后保险杠的最低点。以保证扩散器装置20的设置不会改变后保险杠的最低位置。In one embodiment, when the spoiler 22 opens the opening 101, its lowest point is not lower than the lowest point of the rear bumper, so as to ensure that the setting of the diffuser device 20 does not change the lowest position of the rear bumper.
进一步的一个实施例中,扩散器系统100还包括控制器,控制器与驱动机构21连接,控制器用于输出控制指令,使得驱动机构21驱动扰流板22运动,以打开或关闭开口101。In a further embodiment, the diffuser system 100 further includes a controller, which is connected to the driving mechanism 21 , and is configured to output a control instruction so that the driving mechanism 21 drives the spoiler 22 to move so as to open or close the opening 101 .
本实施例通过控制器的设置可以实现扰流板22的自动开闭控制。In this embodiment, the automatic opening and closing control of the spoiler 22 can be achieved through the setting of the controller.
进一步的一个实施例中,控制器还用于获取车辆当前的行驶速度,并在确定行驶速度大于预设速度阈值时输出第一控制指令,以使得驱动机构21驱动扰流板22打开开口101。在确定行驶速度小于预设速度阈值且大于0时输出第二控制指令,以使得驱动机构21驱动扰流板22关闭开口101。在车辆处于静止状态、迎宾模式开启且检测到解锁信号时,控制扰流板22执行预设动作,预设动作以扰流板22关闭开口101为结束动作。In a further embodiment, the controller is further configured to obtain the current driving speed of the vehicle, and output a first control instruction when it is determined that the driving speed is greater than a preset speed threshold, so that the driving mechanism 21 drives the spoiler 22 to open the opening 101. When it is determined that the driving speed is less than the preset speed threshold and greater than 0, a second control instruction is output, so that the driving mechanism 21 drives the spoiler 22 to close the opening 101. When the vehicle is stationary, the welcome mode is turned on, and an unlocking signal is detected, the spoiler 22 is controlled to perform a preset action, and the preset action ends with the spoiler 22 closing the opening 101.
本实施例的扩散器系统100在车速较小时不开启扰流板22,在车速超过预设速度阈值时开启扰流板22,从而降低升力和风阻。并且在车辆进入迎宾模式且接收到解锁信号时控制扰流板22执行预设动作,以丰富车辆的迎宾响应效果,提高用户使用体验。The diffuser system 100 of this embodiment does not open the spoiler 22 when the vehicle speed is low, and opens the spoiler 22 when the vehicle speed exceeds a preset speed threshold, thereby reducing lift and wind resistance. And when the vehicle enters the welcome mode and receives an unlocking signal, the spoiler 22 is controlled to perform a preset action to enrich the vehicle's welcome response effect and improve the user experience.
一个实施例中,扰流板22位于第二位置时与水平面的夹角为25°-35°中的任一值。In one embodiment, when the spoiler 22 is in the second position, the angle between the spoiler 22 and the horizontal plane is any value between 25° and 35°.
本实施例将扰流板22的打开位置限定为与水平面的夹角为25°-35°中的任一值可以保证扩散器装置20起到较佳的降低升力和风阻的作用。In this embodiment, the opening position of the spoiler 22 is limited to any angle between 25° and 35° with the horizontal plane, which can ensure that the diffuser device 20 plays a better role in reducing lift and wind resistance.
进一步的一个实施例中,扩散器系统100还包括控制按键,用于在被操作时控制扰流板22总成的转动角度。控制按键可以设置在方便用户操作的位置处,在此不作限制。In a further embodiment, the diffuser system 100 further includes a control button for controlling the rotation angle of the spoiler 22 assembly when operated. The control button can be arranged at a position convenient for user operation, which is not limited here.
一个实施例中,扩散器系统100还包括声控单元,用于根据采集到的声音信息控制扰流板22总成的转动角度。In one embodiment, the diffuser system 100 further includes a sound control unit for controlling the rotation angle of the spoiler 22 assembly according to the collected sound information.
也就是说,本实施例中的扩散器装置20可以通过声音控制,通过识别用户语音的方式来自动调节扰流板22的转动角度,有助于驾驶员减少手动操作以减轻注意力的分散,从而有利于驾驶安全性的实现。That is to say, the diffuser device 20 in this embodiment can be controlled by sound, and the rotation angle of the spoiler 22 can be automatically adjusted by recognizing the user's voice, which helps the driver reduce manual operations to alleviate distraction, thereby facilitating the realization of driving safety.
