Description

Technical Field

[0001] This utility model belongs to the field of automotive spoiler technology, and particularly relates to automotive rear spoilers. Background Art

[0002] A car rear bumper spoiler is a component mounted on the bumper of a car, similar to an inverted aircraft tail fin. Its function is to effectively reduce air resistance generated when the vehicle is traveling at high speeds, which saves fuel and improves the stability of the vehicle. The shark fin-shaped spoiler can effectively prevent airflow from rolling up under the car, so that the upper and lower vortices at the rear are balanced, thereby reducing the car's air resistance.

[0003] In the existing technology, spoilers are all designed with a one-piece molding method. Since the spoiler is installed at the bottom of the car, when one of the guide fins on the spoiler is damaged, the spoiler needs to be replaced. Otherwise, it will affect the stability of the car. If it is replaced, the entire spoiler needs to be replaced, which will cost more and also waste resources. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a rear spoiler for automobiles.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a rear spoiler for automobiles, comprising a plate body, wherein a plurality of mounting slots are provided on the plate body, and mounting plates are respectively installed on the inner side of the plurality of mounting slots. A pair of guide fins are installed on the side of the mounting plates away from the mounting slots. A through hole is provided in the mounting slot, and a stop block is provided on the inner side of the through hole. A pair of connecting springs are provided on the side of the plate body away from the mounting plates, and the other ends of the pair of connecting springs are respectively connected to the stop block.

[0006] By adopting the above technical solution, the design of the mounting slot and mounting plate makes the installation process of the rear spoiler simpler and faster. Installers only need to insert the mounting plate into the mounting slot and secure it with the stop and connecting spring; no complex adjustments or calibrations are required. When maintenance or replacement of the rear spoiler is needed, simply loosening the connecting spring allows the mounting plate to be easily removed from the mounting slot. This design not only simplifies the maintenance process but also reduces maintenance costs.

[0007] Optionally, the plate is arc-shaped and is connected to the vehicle via expansion buckles.

[0008] By adopting the above technical solution, the plate is designed in an arc shape, which not only conforms to the streamlined design of the rear of the car, but also guides the airflow more effectively, reduces air resistance, and improves the stability of the vehicle.

[0009] Optionally, the opening ends of several mounting slots are respectively opened to the edge of the plate, and the two sides of the mounting slots are respectively provided with grooves for mounting the mounting plate.

[0010] By adopting the above technical solution, the opening end of the mounting groove is located at the edge of the plate, which allows the mounting plate to be directly inserted into the mounting groove from the edge without complicated positioning or adjustment steps. At the same time, the groove design provides additional guidance and support for the mounting plate, allowing it to slide into the mounting groove more smoothly during installation. This design not only simplifies the installation process but also improves installation efficiency, making it easier for users to complete the installation and disassembly work.

[0011] Optionally, rubber pads are respectively installed on the surface of the mounting plate and the inner side of the mounting groove, and the rubber pads on the inner side of the mounting groove are in contact with the end of the mounting plate.

[0012] By adopting the above technical solution, the design of the rubber pad can reduce the friction between the mounting plate and the mounting groove, reduce noise, and at the same time increase the sealing performance to prevent airflow from leaking from the gaps, thus ensuring the airflow guiding effect of the spoiler.

[0013] Optionally, connecting seats are installed on both sides of the stop block, and the side of the connecting seat closest to the plate is connected to the connecting spring.

[0014] By adopting the above technical solution, the connecting seat, as an intermediary structure between the connecting spring and the stop block, can ensure that the force line of the connecting spring acts more stably on the stop block; when the vehicle is driving on bumpy roads or encountering other dynamic loads, the connecting seat can effectively disperse and resist these forces, preventing the stop block or mounting plate from loosening or falling off due to uneven force, thereby improving the stability of the entire rear spoiler.

[0015] Optionally, the plate body has a plurality of pairs of fixing grooves on the side away from the mounting plate, and the plurality of pairs of fixing grooves are symmetrically distributed on both sides of the through hole, and one end of the connecting spring is connected to the inner sidewall of the fixing groove.

[0016] By adopting the above technical solution, the design of the fixing groove provides a stable fixing point for the connecting spring, ensuring that the connecting spring will not shift or fall off during installation, thus improving the overall stability.

[0017] Optionally, the mounting plate is integrally formed with the pair of guide fins.

[0018] By adopting the above technical solutions, the one-piece molding design not only simplifies the installation steps and reduces installation costs, but also improves the overall strength and stability.

[0019] Optionally, the surface of the guide fin is provided with a microporous structure.

[0020] By adopting the above technical solution, the microporous structure can reduce air resistance and promote airflow, while also having a certain noise reduction function, making the vehicle more stable and quiet when driving at high speed.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This utility model achieves modularity of the spoiler by designing a detachable mounting plate and guide fin. When a guide fin is damaged, it is not necessary to replace the entire spoiler; only the damaged guide fin and its corresponding mounting plate need to be replaced. This design greatly reduces maintenance costs and also reduces resource waste, reflecting the concepts of environmental protection and economy.

[0023] 2. The design of the mounting slot and stop, as well as the introduction of the connecting spring, makes the installation and removal of the mounting plate and guide fin plate simple and quick. This not only improves installation efficiency, but also reduces the technical requirements for installers, allowing ordinary car owners to easily complete the replacement or maintenance work.

[0024] 3. The spoiler design of this utility model has high flexibility and can be customized and installed according to different car models and individual needs. Its detachable guide fins provide car owners with more choices and customization space, meeting the actual needs of different users. Attached Figure Description

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] like Figure 1 As shown in Figure 4, the specific solution of the embodiment is as follows: a rear spoiler for a car, including a plate body 1, the plate body 1 being arc-shaped, the plate body 1 being connected to the car via expansion buckles. The arc-shaped design of the plate body 1 not only conforms to the streamlined design of the rear of the car, but also more effectively guides airflow, reduces air resistance, and improves the stability of the vehicle. The plate body 1 is connected to the car via expansion buckles, which is a simple and easy connection method that does not require complicated installation steps, while ensuring that the plate body 1 is firmly installed on the car and is not easy to fall off.

[0033] The plate 1 has several mounting slots 2. The design of the mounting slots 2 facilitates the installation and removal of the mounting plate 3. At the same time, the number and position of the mounting slots 2 can be designed according to actual needs to meet different vehicle models and personalized requirements. The opening ends of the mounting slots 2 are respectively opened to the edge of the plate 1. The two sides of the mounting slots 2 are respectively provided with grooves 201 for the mounting plate 3 to be installed. The opening of the grooves 201 ensures that the mounting plate 3 is stable and does not shake in the mounting slots 2, thereby improving the overall stability.

[0034] A mounting plate 3 is installed on the inner side of several mounting slots 2. The mounting plate 3 is made of high-strength material, such as lightweight high-strength alloy or carbon fiber composite material, which can reduce its weight and improve fuel economy. It can withstand the airflow impact generated when the vehicle is driving at high speed. Rubber pads 301 are installed on the surface of the mounting plate 3 and the inner side of the mounting slot 2, respectively. The rubber pads 301, such as silicone rubber, nitrile rubber or neoprene rubber, can meet the requirements of high temperature resistance, aging resistance and sealing performance. The rubber pads 301 are bonded to the mounting plate 3 and the mounting slot 2. The rubber pads 301 on the inner side of the mounting slot 2 are attached to the end of the mounting plate 3. The design of the rubber pads 301 can reduce the friction and noise between the mounting plate 3 and the mounting slot 2, while increasing the sealing performance and preventing airflow from leaking from the gaps.

[0035] A pair of air guide fins 4 are mounted on the side of the mounting plate 3 away from the mounting groove 2. The air guide fins 4 have a streamlined design, which not only conforms to aerodynamic principles but also enhances the overall aesthetics of the vehicle. The pair of air guide fins 4 can more effectively guide airflow, reduce air resistance, improve vehicle stability, simplify installation steps, and reduce installation costs. The mounting plate 3 and the pair of air guide fins 4 are integrally formed, which improves the overall strength and stability. The surface of the air guide fins 4 has a microporous structure, which can reduce air resistance and promote airflow, while also having a certain noise reduction function, making the vehicle more stable and quiet when driving at high speeds.

[0036] The mounting groove 2 has a through hole 5, and a stop block 6 is provided inside the through hole 5. Connecting seats 601 are installed on both sides of the stop block 6. The side of the connecting seat 601 close to the plate 1 is connected to the connecting spring 7. The stop block 6 is installed inside the through hole 5 of the mounting groove 2 to prevent the mounting plate 3 from falling out of the mounting groove 2.

[0037] Connecting seats 601 are installed on both sides of the stop block 6 to connect connecting springs 7, ensuring the stability of the mounting plate 3 in the mounting groove 2. A pair of connecting springs 7 are provided on the side of the plate 1 away from the mounting plate 3. The other end of the pair of connecting springs 7 is connected to the stop block 6 respectively. Several pairs of fixing grooves 101 are opened on the side of the plate 1 away from the mounting plate 3. The several pairs of fixing grooves 101 are symmetrically distributed on both sides of the through hole 5. One end of the connecting spring 7 is connected to the inner side wall of the fixing groove 101. The fixing grooves 101 are opened on the side of the plate 1 away from the mounting plate 3 and symmetrically distributed on both sides of the through hole 5. This design can ensure that the connecting spring 7 has a stable fixing point during installation, improving the overall stability. The design of the fixing groove 101 simplifies the installation steps of the connecting spring 7 and reduces installation costs and time.

[0038] The working principle of the above embodiment is:

[0039] Before installation, connect the connecting spring 7 to the stop block 6, and connect the plate 1 to the rear of the car using expansion buckles. Next, before installing the mounting plate 3, press the stop block 6 so that it is parallel to the mounting groove 2. At this time, the connecting spring 7 is in a stretched state. Then, slowly insert the mounting plate 3 along the opening end of the mounting groove 2 until it is completely inside the mounting groove 2. During this process, pay special attention to the contact between the rubber pad 301 on the surface of the mounting plate 3 and the rubber pad 301 on the inside of the mounting groove 2. Once the mounting plate 3 is fully in place, the stop block 6 will naturally spring back to its original position under the action of the connecting spring 7, pressing tightly against the side of the mounting plate 3 to further increase its stability. At this time, check whether the other end of the connecting spring 7 is firmly connected to the fixing groove 101 on the plate 1 to ensure the integrity and stability of the entire installation structure.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
