Technical Field

[0001] The utility model relates to an automobile spoiler device, in particular to an automobile spoiler accessory device with a main spoiler and an auxiliary spoiler. Background Art

[0002] Vehicles will be subject to air resistance during driving. The air passes over and under the vehicle at different speeds, which will produce a pressure difference and cause the vehicle to generate lift, which will affect the stability of the vehicle's driving.

[0003] To solve the above problems, vehicles usually install a rear wing at the trunk position to improve the stability of the vehicle's driving from an aerodynamic perspective.

[0004] But for high-performance vehicles such as sports cars, a single spoiler may not be able to achieve optimal performance requirements.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in this field. Utility Model Content

[0006] Purpose of the utility model: The technical problem to be solved by the utility model is to provide a car spoiler accessory device in view of the deficiencies in the prior art, which can solve the technical problem that the use of a single spoiler in the prior art cannot further optimize the aerodynamic characteristics of the vehicle.

[0007] In order to solve the above technical problems, the utility model discloses a vehicle spoiler accessory device, which comprises:

[0008] A base for connecting the vehicle body;

[0009] a main spoiler located above the base;

[0011] A driving unit mounted on the base, the driving unit being configured to drive the transmission mechanism;

[0012] and a secondary spoiler located below the main spoiler, wherein the secondary spoiler can be lifted and lowered relative to the base.

[0013] In one embodiment, the device comprises an elastic element, wherein the elastic element comprises a stationary connection end and an elastic lifting end, wherein the stationary connection end remains stationary relative to the base, and the elastic lifting end is fixedly connected to the auxiliary spoiler;

[0014] The elastic element can generate an elastic force on the secondary spoiler in an upward direction, and the elastic force causes the secondary spoiler to press directly or indirectly against the main spoiler, so that the secondary spoiler moves with the main spoiler;

[0015] When the secondary spoiler rises to a specified height along with the main spoiler, the main spoiler can continue to rise so that the secondary spoiler is detached from the main spoiler.

[0016] Furthermore, it also includes a limiting structure, which is arranged on the base; under the action of the elastic force generated by the elastic element in the ascending direction, the auxiliary spoiler rises synchronously with the main spoiler until the elastic lifting end abuts against the limiting structure, and the main spoiler can continue to rise to disengage the auxiliary spoiler from the main spoiler.

[0017] Optionally, the elastic element is a compression spring, and the stationary connection end of the elastic element is located below the elastic lifting end of the elastic element.

[0018] Optionally, the elastic element is a tension spring, and the stationary connection end of the elastic element is located above the elastic lifting end of the elastic element.

[0019] Optionally, the device comprises an independent guide member for guiding the elastic element, wherein the guide member is fixedly connected to the base indirectly or directly. The elastic element is coaxially sleeved on the outer side of the guide member.

[0020] Specifically, the transmission mechanism includes a first lifting assembly, a second lifting assembly and a conversion mechanism;

The sliding sleeve of the first lifting assembly is connected to the main spoiler via a first hinge shaft, and the sliding sleeve of the second lifting assembly is connected to the other end of the main spoiler via the conversion mechanism, and the conversion mechanism is used to convert the lifting motion of the sliding sleeve of the second lifting assembly relative to the sliding sleeve of the first lifting assembly into a flipping motion of the main spoiler around the first hinge shaft. When the two sliding sleeves are lifted and lowered synchronously, the transmission mechanism drives the main spoiler to perform only lifting motion.

[0023] The elastic element is coaxially sleeved on the outer peripheral wall of the guide sleeve in the transmission mechanism.

[0024] Specifically, the device comprises a secondary spoiler mounting bracket, and the secondary spoiler mounting bracket is fixedly connected to the elastic lifting end of the elastic element and the secondary spoiler, so that the elastic lifting end is fixedly connected to the secondary spoiler.

[0044] Example 1

[0045] like Figures 1 to 3 As shown, this embodiment discloses a spoiler attachment device for an automobile, which includes a base 1 for fixedly connecting the vehicle body, a main spoiler 2 located above the base 1, a transmission mechanism 3 installed on the base 1, a driving unit 4 installed on the base 1, and a secondary spoiler 5. The transmission mechanism 3 is connected to the main spoiler 2, and is used to drive the main spoiler 2 to move up and down and flip relative to the base 1. The driving unit 4 is used to drive the transmission mechanism 3. The secondary spoiler 5 is located below the main spoiler 2 and can be lifted and lowered relative to the base 1.

[0046] This embodiment adopts a main spoiler 2 and a secondary spoiler 5 located below the main spoiler 2, and the cooperation of the two can further optimize the aerodynamic characteristics of the vehicle.

[0047] Specifically, the transmission mechanism 3 includes a first lifting assembly, a second lifting assembly and a conversion mechanism 350 .

[0048] See also Figure 4 The first lifting assembly and the second lifting assembly adopt the same structure, including a screw rod 310, a sliding sleeve 320 and a guide sleeve 330. The screw rod 310 is inserted into the sliding sleeve 320 and forms a thread pair with the sliding sleeve 320, which is used to make the sliding sleeve 320 rise and fall relative to the screw rod 310 when the screw rod 310 rotates. The sliding sleeve 320 is slidably sleeved in the guide sleeve 330, and the guide sleeve 330 is fixedly connected to the base 1.

[0049] Each screw rod 310 is rotatably mounted on the base 1. The sliding sleeve 320 of the first lifting assembly is connected to the main spoiler 2 through the first hinge shaft 340, and the sliding sleeve 320 of the second lifting assembly is connected to the other end of the main spoiler 2 through the conversion mechanism 350. The conversion mechanism 350 is used to convert the lifting motion of the sliding sleeve 320 of the second lifting assembly relative to the sliding sleeve 320 of the first lifting assembly into the flipping motion of the main spoiler 2 around the first hinge shaft 340. When the two sliding sleeves 320 are lifted and lowered synchronously, the transmission mechanism 3 drives the main spoiler 2 to perform only lifting motion.

[0050] See also Figure 3 The conversion mechanism 350 may be a connecting rod, and the two ends of the connecting rod are respectively hinged to the sliding sleeve 320 of the second lifting assembly and the main spoiler 2. Figure 5 The conversion mechanism 350 can also be a slide groove. When the sliding sleeve 320 of the second lifting assembly moves up and down relative to the sliding sleeve 320 of the first lifting assembly, one end of the sliding sleeve 320 of the second lifting assembly slides in the slide groove to realize the flipping movement of the main spoiler 2 around the first hinge shaft 340.

[0051] Specifically, see Figure 1 The driving unit 4 includes a first driving unit for driving the first lifting assembly and a second driving unit for driving the second lifting assembly.

[0052] like Figure 6 As shown, the first driving unit and the second driving unit adopt the same mechanism, both including a driving motor 410 , a worm 420 connected to the driving motor 410 via a transmission shaft, and a worm wheel 430 meshing with the worm 420 .

[0053] The worm gear 430 of the first driving unit is coaxially fixedly connected to the lead screw 310 in the first lifting assembly, and the worm gear 430 of the second driving unit is coaxially fixedly connected to the lead screw 310 in the second lifting assembly.

[0054] In order to realize that the secondary spoiler 5 can be raised and lowered relative to the base 1, as shown in FIG. Figure 1 As shown, in this embodiment, the device includes an elastic element 6, which includes a stationary connection end 610 and an elastic lifting end 620. The stationary connection end 610 remains stationary relative to the base 1, and the elastic lifting end 620 is fixedly connected to the auxiliary spoiler 5.

[0055] like Figure 7 As shown, the elastic element 6 can generate an elastic force toward the ascending direction on the secondary spoiler 5, and the elastic force causes the secondary spoiler 5 to press directly or indirectly against the main spoiler 2, so as to make the secondary spoiler 5 follow the main spoiler 2. During the following process, the main spoiler 2 can only be raised or lowered or accompanied by the adjustment of the flip angle. When the secondary spoiler 5 rises to a specified height with the main spoiler 2, the main spoiler 2 can continue to rise to disengage the secondary spoiler 5 from the main spoiler 2, and further expand the flip angle.

[0056] In this embodiment, before the secondary spoiler 5 is separated from the primary spoiler 2, the secondary spoiler 5 is in contact with the primary spoiler 2 and has no spoiling effect; after the separation, the secondary spoiler 5 has a spoiling effect.

[0057] In some embodiments of the specified height, the device includes a limiting structure 51 for limiting the upper position of the secondary spoiler 5. Under the elastic force generated by the elastic element 6 in the ascending direction, the secondary spoiler 5 is synchronously lifted and lowered with the main spoiler 2 until the elastic lifting end 620 abuts against the limiting structure 51, and the main spoiler 2 can continue to rise so that the secondary spoiler 5 is disengaged from the main spoiler 2. The position of the limiting structure 51 defines the specified height. In a specific embodiment, see Figure 5 The limiting structure 51 is a crossbeam, and the crossbeam is connected between the guide sleeve 330 of the first lifting assembly and the guide sleeve 330 of the second lifting assembly.

[0058] It should be understood that the limiting structure 51 may be other structures, such as a boss structure provided on the outer side wall of the guide sleeve 330 .

[0059] In some embodiments of the elastic element 6, see Figure 1 The elastic element 6 is a compression spring, and the stationary connection end 610 of the elastic element 6 is located below the elastic lifting end 620 of the elastic element 6 .

[0060] In some other embodiments of the elastic element 6, see Figure 8The elastic element 6 is a tension spring, and the stationary connection end 610 of the elastic element 6 is located above the elastic lifting end 620 of the elastic element 6.

[0061] In order to guide the elastic element 6, in this embodiment, the elastic element 6 is guided by the transmission mechanism 3. Figure 1 As shown, the elastic element 6 can be coaxially sleeved on the outer peripheral wall of any guide sleeve 330 in the transmission mechanism 3 to guide the elastic element 6. Specifically, the outer peripheral wall of the guide sleeve 330 can be cylindrical.

[0062] It is worth noting that in some other embodiments, see Fig. 9 The device comprises an independent guide member 7 for guiding the elastic element 6, and the guide member 7 is directly or indirectly fixedly connected to the base 1. The elastic element 6 is coaxially sleeved on the outer side of the guide member 7.

[0063] like Figure 1 As shown, in some embodiments, the transmission mechanism 3 is provided with two sets, which are respectively arranged on opposite sides of the base 1, and the secondary spoiler 5 is located between the two transmission mechanisms. Therefore, when the elastic element 6 is guided by the transmission mechanism 3, the device includes a secondary spoiler mounting bracket 9, and the secondary spoiler mounting bracket 9 is fixedly connected to the elastic lifting end 620 of the elastic element 6 and the secondary spoiler 5, so that the elastic lifting end 620 is fixedly connected to the secondary spoiler 5.

[0064] In this embodiment, if Figure 2 As shown, the device includes a pressure plate 8, which is directly or indirectly fixedly connected to the bottom of the main spoiler 2. The main spoiler 2 can be pressed against the secondary spoiler 5 through the pressure plate 8 or against the secondary spoiler mounting bracket 9 fixedly connected to the secondary spoiler 5, thereby achieving indirect pressing of the main spoiler 2 against the secondary spoiler 5.

[0065] It should be understood that the device may not include a pressure plate, and the primary spoiler 2 can directly press against the secondary spoiler 5 .

[0066] It should be understood that the main spoiler 2 can be directly connected to the transmission mechanism 3. The main spoiler 2 can also be connected to the transmission mechanism 3 through the mainboard mounting plate 12. In this case, the first hinge shaft 340 and the slide slot are arranged on the mainboard mounting plate 12.

[0067] Example 2

[0068] Different from the first embodiment in which the elastic force of the elastic element is used to make the secondary spoiler 5 move with the main spoiler 2, the present embodiment uses an independent electric drive device to drive the secondary spoiler 5 to move up and down.

[0069] In this embodiment, see Fig.10The device includes a third transmission mechanism 10 for driving the auxiliary spoiler 5 to rise and fall, and a third driving unit 11 for driving the third transmission mechanism 10 . Both the third transmission mechanism 10 and the third driving unit 11 are installed on the base 1 .

[0070] The third transmission mechanism 10 can adopt the same structure as the first lifting assembly in the first embodiment. The third driving unit 11 can adopt the same structure as the first driving unit in the first embodiment.

[0071] Compared with the follow-up mode in Example 1, this embodiment directly drives the auxiliary spoiler 5 to rise and fall by setting a third transmission mechanism 10 and a third drive unit 11, so that the auxiliary spoiler 5 can be adjusted when the main spoiler 2 is in a low position state, thereby meeting the working conditions at different vehicle speeds.

[0072] The utility model provides a thought and method for a spoiler attachment device for an automobile. There are many methods and ways to implement the technical solution. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
