[0014] In a possible implementation, the spring piece includes a straight section and a bent section;

[0015] The straight section extends along the axial direction of the column, and the distance between the bent section and the side wall of the column gradually increases in a direction away from the straight section.

[0016] In a possible implementation, assuming that the length of the column is L1, and the length of the bending section is L2, then 1 / 2L1≤L2≤2 / 3L2.

DETAILED DESCRIPTION

[0055] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0056] The terms used in the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and are not intended to limit the present disclosure.

[0057] In the current market, in order to improve driving stability, more and more vehicles are equipped with tail wing assemblies at the rear. Installing the tail wing assembly on the vehicle can reduce the lift at the rear of the car, thereby improving the vehicle's grip.

[0058] In the related art, the rear cover outer plate has a mounting hole. The tail assembly includes a tail body, bolts, nuts and a rear cover outer plate. The rear cover outer plate has a mounting hole. The tail body is fixedly connected to the mounting hole through bolts and nuts. In the actual installation process, the tail body must first be arranged on the rear cover outer plate, and the bolts must be passed through the mounting holes. Then the rear cover outer plate is opened, and the nuts and bolts are connected inside the rear cover outer plate, so as to achieve the fixation of the tail assembly on the rear shell outer plate.

[0059] The tail body usually includes two sets of lifting mechanisms, one set of actuators and a base plate. The base plate is a double-layer structure of inner and outer plates, and the internal structure is fully reinforced, which makes the overall weight of the tail body heavier. Therefore, in the actual installation process, when the rear cover outer panel is opened, the rear cover outer panel and the tail body tilt. If protective measures are taken for the tail body outside the rear cover outer panel, the tail body will be at risk of falling due to its heavy weight. This may cause damage to the tail body, windshield, etc. or other surrounding parts.

[0060] In view of the above technical problems, an embodiment of the present disclosure provides a tail assembly, which can pre-hang the tail body on the rear cover outer panel to prevent the tail body from falling off during the process of opening the rear cover outer panel. The tail assembly provided by the embodiment of the present disclosure is exemplarily described below:

[0061] like Figure 1-Figure 4 As shown, the tail assembly includes a tail body 1, a first mounting stud 2, a buckle 3, a rear cover outer panel 4 and a nut. The first mounting stud 2 is fixed to the tail body 1, and the tail body 1 is located on the outside of the rear cover outer panel 4. The first mounting stud 2 passes through the first mounting hole 4a of the rear cover outer panel 4, and the nut is located on the inner side of the rear cover outer panel 4 and connected to the first mounting stud 2. The buckle 3 includes a column 31 and a plurality of spring pieces 32, the column 31 is connected to the tail body 1, and the plurality of spring pieces 32 are distributed on the outer wall of the column 31 along the circumferential direction, and the distance between the spring piece 32 and the side wall of the column 31 gradually increases along the direction close to the tail body 1. The column 31 and the spring piece 32 pass through the second mounting hole 4b of the rear cover outer panel 4, and the spring piece 32 abuts against the inner wall of the rear cover outer panel 4.

[0062] The spring sheet 32 ​​has an unfolded state and a stowed state. Figure 4 As shown, in the unfolded state, the maximum outer diameter of the plurality of spring pieces 32 is greater than the inner diameter of the second mounting hole 4b. Figure 5 As shown, in the storage state, the maximum outer diameter of the plurality of spring pieces 32 is less than or equal to the inner diameter of the second mounting hole 4b. In the storage state, the spring piece 32 can fit the outer wall of the column 31. When the spring piece 32 passes from the outside of the rear cover outer plate 4 into the inside thereof, under the pressure of the side wall of the second mounting hole 4b, the spring piece 32 gradually changes from the deployed state to the storage state. When the spring piece 32 passes from the inside of the rear cover outer plate 4 to the outside thereof, the spring piece 32 can be manually pressed to put the spring piece 32 in the storage state.

[0063] The technical solution provided by the embodiment of the present disclosure is that when the tail wing body 1 is installed on the rear cover outer panel 4, the buckle 3 is first aligned with the second mounting hole 4b, and the buckle 3 is passed through the second mounting hole 4b. Under the pressure of the side wall of the second mounting hole 4b, the spring piece 32 is deformed and gradually approaches the column 31, so that the spring piece 32 can smoothly pass through the second mounting hole 4b. After the spring piece 32 passes through the second mounting hole 4b, the spring piece 32 abuts against the inner wall of the rear cover outer panel 4. Then, the rear cover outer panel 4 is opened, and the tail wing body 1 is fixed to the rear cover outer panel by connecting the first mounting stud 2 and the nut. In the process of installing the nut, since the spring piece 32 abuts against the inner wall of the rear cover outer panel 4, the spring piece 32 can clamp the tail wing body 1 on the rear cover outer panel 4, thereby preventing the tail wing body 1 from falling off from the rear cover outer panel 4 when the rear cover outer panel 4 is opened.

[0064] In addition, when the empennage body 1 needs to be removed from the rear cover outer panel 4, the nut is first removed, and then the spring sheet 32 ​​is manually pressed to the storage state, so that the outer diameter of the spring sheet 32 ​​is smaller than the outer diameter of the second mounting hole 4b, and the spring sheet 32 ​​can be passed through the second mounting hole 4b, thereby removing the empennage assembly.

[0065] The following is an exemplary description of the implementation of the buckle 3.

[0066] In some examples, such as Figure 3 and Figure 4 As shown, the tail assembly also includes a second mounting stud 5, which is fixed to the tail body 1. The column 31 has a threaded hole 31a, which is connected to the second mounting stud 5. Before installing the tail body 1 on the rear cover outer panel 4, first connect the buckle 3 to the second mounting stud 5. Then pass the buckle 3 through the second mounting hole 4b. When it is necessary to remove the tail body 1 from the rear cover outer panel 4, the buckle 3 can be removed from the second mounting stud 5. In this way, the disassembly methods of the tail body 1 can be increased. If the spring piece 32 of the buckle 3 is difficult to be manually squeezed to the storage state, the buckle 3 can also be directly removed.

[0067] For example, Figure 7 As shown, the end of the column 31 away from the tail body 1 has a blind hole 31b, and the blind hole 31b is a hexagonal hole. When the tail body 1 needs to be removed from the rear cover outer plate 4, the nut is removed first. Then, an external hexagonal wrench can be inserted into the blind hole 31b to remove the buckle 3 from the second mounting stud 3, and then the second mounting stud 3 is taken out from the second mounting hole 4b, thereby completing the removal of the tail body 1.

[0068] In some other examples, the blind hole 31b may also be a cross hole or a slotted hole. In this way, the buckle 3 can be disassembled using a screwdriver.

[0069] It can be understood that, since the column 31 has both the blind hole 31 b and the threaded hole 31 a , the threaded hole 31 a is also configured as a blind hole.

[0070] In some examples, the second mounting stud 3 is implanted and welded on the empennage body 1. There will be welding slag at the connection between the second mounting stud 3 and the empennage body 1. In order to prevent the welding slag from squeezing the column 31 of the buckle 3, the height of the threaded hole 31a is set to be smaller than the length of the second mounting stud 3. In this way, after the buckle 3 and the second mounting stud 3 are tightened, the column 31 will not abut the connection between the second mounting stud 3 and the empennage body 1, so that the column 31 is not easily squeezed and deformed by the welding slag.

[0071] In some examples, such as Figure 1 As shown, the tail assembly includes two buckles 3 and a plurality of first mounting studs 2. The two buckles 3 are symmetrical about the symmetry axis A of the tail body 1, one or more first mounting studs 2 are arranged between the two buckles 3, and one or more first mounting studs 2 are arranged on both sides of the two buckles 3 respectively.

[0072] Since the buckles 3 only play a pre-hanging role, there is no need for too many buckles 3. The two buckles 3 are symmetrical about the symmetry axis A. When the tail body 1 is pre-hung on the rear cover outer plate 4, the force is more uniform.

[0073] In some examples, the plurality of spring pieces 32 are evenly distributed along the circumference of the column 31. In this way, when the tail wing body 1 is pre-hung on the rear cover outer panel 4, the force is more evenly applied.

[0074] In some examples, such as Figure 6 and Figure 7 As shown, the spring piece 32 includes a straight section 321 and a bent section 322. The straight section 321 extends along the axial direction of the column 31, and the distance between the bent section 322 and the side wall of the column 31 gradually increases in a direction away from the straight section 321.

[0075] When the tail body 1 tends to fall off, the bending section 322 will be greatly deformed. If the deformation of the bending section 322 is too large, it will cause the straight section 321 to deviate and deform. In this way, it can avoid the deformation of the bending section 322 relative to the straight section 321 to be too large, reducing the risk of the spring sheet 32 ​​being damaged.

[0076] The width of the straight section 321 along the circumferential direction may be equal to the width of the bent section 322 along the circumferential direction.

[0077] In some examples, such as Figure 7 As shown, assuming that the length of the column 31 is L1 and the length of the bent section 322 is L2, 1 / 2L1≤L2≤2 / 3L2. This facilitates the spring 32 to pass through the second mounting hole 4b from the outside of the rear cover outer plate 4 and be clamped on the inside of the rear cover outer plate 4.

[0078] If L2 is too small, the spring sheet 32 ​​will not be easily deformed, so that it will be difficult for the spring sheet 32 ​​to pass through the second mounting hole 4 b , making it difficult for the tail wing body 1 to be mounted on the rear cover outer panel 4 .

[0079] If L2 is too large, the bending section 322 will be too long, which makes it easy for the bending section 322 to deform. Before the first mounting stud 2 is connected to the nut, after the buckle 3 passes through the second mounting hole 4b from the outside of the rear cover outer panel 4, the bending section 322 is easily squeezed and deformed by the rear cover outer panel 4, which makes it easy for the buckle 3 to move axially, and then makes it easy for the tail body 1 to move axially.

[0080] In some examples, such as Figure 6 and Figure 7 As shown, the number of the spring pieces 32 is 2 to 5. In this way, it is advantageous to install the buckle 3 to the inner side of the rear cover outer plate 4, and it is also advantageous to disassemble the buckle 3.

[0081] If the number of the spring pieces 32 is too small, it will be difficult for the spring pieces 32 to be clamped on the inner side of the rear cover outer panel 4 , so that the tail wing body 1 still has the risk of falling off from the rear cover outer panel 4 .

[0082] When disassembling the empennage body 1, the spring pieces 32 need to be manually pressed to the storage state. Therefore, if there are too many spring pieces 32, it will be more difficult to manually press the spring pieces 32, which is not conducive to pressing the spring pieces 32 to the storage state.

[0083] Exemplarily, the number of the spring pieces 32 is three.

[0084] In some examples, such as Figure 6 and Figure 7 As shown, the side wall of the column 31 has a plurality of reinforcing ribs 311. The plurality of reinforcing ribs 311 are evenly distributed along the circumference of the column 31, and the reinforcing ribs 311 extend along the axial direction of the column 31, and each spring piece 32 is located between two adjacent reinforcing ribs 311. In this way, the structural strength of the column 31 can be strengthened, so that the buckle 3 is not easily damaged.

[0085] Exemplarily, one end of the reinforcing rib 311 away from the tail body 1 is connected to one end of the straight section 321 of the spring piece 32 away from the tail body 1 .

[0086] In some examples, such as Figure 6 As shown, along the radial direction of the column 31, the thickness of the reinforcing rib 311 is D1, and the thickness of the straight section 321 and the bent section 322 is D2, then D1 = D2. An escape groove is formed between two adjacent reinforcing ribs 311. In the storage state, the spring sheet 32 ​​is located in the escape groove, and the outer wall of the spring sheet 32 ​​and the outer wall of the reinforcing rib 311 can form a circle, which is conducive to the spring sheet 32 ​​passing through the second mounting hole 4b. In this way, it is convenient to install or remove the buckle 3.

[0087] Alternatively, in some other examples, D1 may also be greater than D2, which is not specifically limited in the embodiments of the present disclosure.

[0088] It can be understood that the number of the reinforcing ribs 311 is equal to the number of the spring pieces 32 .

[0089] In some examples, such as Figure 6 and Figure 7 As shown, there is a gap 30 between the side wall of the bending section 322 and the side wall of the reinforcing rib 311. In this way, when the spring sheet 32 ​​is in the stowed state, the side wall of the bending section 322 will not contact the side wall of the reinforcing rib 311. When the spring sheet 32 ​​is no longer under pressure, the spring sheet 32 ​​can automatically return to the unfolded state.

[0090] If the side wall of the bent section 322 contacts the side wall of the reinforcing rib 311, friction will be generated between the side wall of the bent section 322 and the side wall of the reinforcing rib 311, which is not conducive to the spring piece 32 automatically restoring from the storage state to the deployment state. If the spring piece 32 cannot automatically restore from the storage state to the deployment state during the process of the tail body 1, the buckle 3 cannot be engaged with the inner side of the rear cover outer plate 4, and the tail body 1 is easy to fall off from the rear cover outer plate 4.

[0091] In some examples, the buckle 3 is integrally injection molded, so that the column 31 and the spring sheet 32 ​​have a higher connection strength, so that the spring sheet 32 ​​is not easy to fall off from the column 31, thereby enhancing the connection strength between the tail assembly and the rear cover outer panel 4.

[0092] Exemplarily, the buckle 3 is made of plastic.

[0093] Of course, in other examples, the material of the buckle may also be metal, and the embodiments of the present disclosure do not specifically limit this.

[0094] In some examples, such as Figure 1 As shown, the two sides of the tail assembly also include a main positioning pin 6 and a secondary positioning pin 7. The rear cover outer panel 4 has corresponding main positioning holes and secondary positioning holes, the main positioning pin 6 extends into the main positioning hole, and the secondary positioning pin 7 extends into the secondary positioning hole, so as to realize the positioning of the tail assembly on the rear cover outer panel 4.

[0095] In some examples, the outer diameter of the column 31 is smaller than the inner diameter of the second mounting hole 4b. In this way, the side wall of the column 31 and the side wall of the second mounting hole 4b will not fit together. Therefore, the column 31 and the second mounting hole 4b will not radially limit the tail body 1. In this way, the side wall of the column 31 and the second mounting hole 4b will not affect the positioning function of the main positioning pin 6 and the auxiliary positioning pin 7, and the problem of over-positioning between the tail body 1 and the rear cover outer plate 4 can be avoided.

[0096] For example, Figure 1 As shown, a plurality of second mounting studs 3 are located between the main locating pins 6 and the auxiliary locating pins 7 .

[0097] The disclosed embodiment also provides a vehicle, the vehicle comprising the above-mentioned tail wing assembly.

[0098] The technical solution provided by the embodiment of the present disclosure is that before the tail wing body 1 is installed on the rear cover outer panel 4, the buckle 3 is first threadedly connected with the second mounting stud 3. Then the buckle 3 is aligned with the second mounting hole 4b, and the buckle 3 is passed through the second mounting hole 4b. Under the pressure of the side wall of the second mounting hole 4b, the spring sheet 32 ​​is deformed and gradually approaches the column 31, so that the spring sheet 32 ​​can smoothly pass through the second mounting hole 4b. After the spring sheet 32 ​​passes through the second mounting hole 4b, the spring sheet 32 ​​returns to the unfolded state. Then, the rear cover outer panel 4 is opened, and the tail wing body 1 is fixed to the rear cover outer panel 4 by connecting the first mounting stud 2 and the nut. In the process of installing the nut, since the spring sheet 32 ​​is in the unfolded state, the spring sheet 32 ​​can clamp the tail wing body 1 on the rear cover outer panel 4, thereby preventing the tail wing body 1 from falling off from the rear cover outer panel 4. Thereby preventing the tail wing body 1 from falling and colliding with other parts of the vehicle.

[0099] The present disclosure does not specifically limit the type of vehicle, for example, a sedan, a bus, a truck, a sport utility vehicle (SUV), etc.

[0100] The rear wing assembly in the disclosed embodiment can be installed in a hybrid electric vehicle (HEV), such as an extended-range vehicle, a plug-in vehicle, etc., and can also be used in a traditional fuel vehicle (Internal Combustion Engine, ICE).

[0101] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
