[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0038] like Figures 1-9 As shown, the car spoiler and its assembly method include a main board 1, a top plate 2 along the vehicle height direction, side plates 3 at both ends of the top plate 2 along the vehicle width direction, and a support plate 4 connected to the main board 1 on the lower side of the top plate 2. The side plates 3 are connected to the main board 1 via connecting seats 13. Specifically, the main board 1 is elongated, and there are two top plates 2 symmetrically arranged on the upper side of the main board 1. The support plate 4 is located on the lower side of the top plate 2, with one end of the top plate 2 extending beyond the main board 1 in the width direction. The support plate 4 supports the top plate 2, thereby achieving the desired spoiler assembly. The spoiler is stably placed on the motherboard 1. The connector 13 is T-shaped, with one end connected to the motherboard and the other end connected to the side plate 3. In this embodiment, the motherboard 1 is hollow, thereby reducing the weight of the spoiler. In this embodiment, the motherboard 1, top plate 2, support plate 4, connector 13 and side plate 3 are all integrally molded parts. In this embodiment, the above-mentioned components are injection molded. The overall spoiler is assembled from the above-mentioned components, realizing the manufacturing and assembly of the spoiler in this embodiment, thereby increasing the spoiler effect of the spoiler in this embodiment.

[0039] The top plate 2 set on the main board 1 and the side plates 3 set on both sides of the main board 1 turbulent the airflow when the car moves, reducing the lift at the rear of the vehicle, thereby improving the performance of the spoiler. The top plate 2 is bonded to the main board 1, and the side plates 3 are bonded to the main board 1 through the connecting seat 13, which facilitates the manufacture of the spoiler. Thus, the spoiler increases the turbulence performance while being easy to manufacture, making it more practical.

[0040] Specifically, refer to Figure 1 The main board 1 includes two symmetrically arranged wing plates 101. The wing plates 101 are connected to the support plate 4, and the support plate 4 is bonded to the top plate 2. The support plate 4 supports the top plate 2 on the wing plate 101, thereby ensuring the stable connection of the top plate 2 on the wing plate 101. The wing plate 101 is provided with a mounting bracket 26 on its lower side. The mounting bracket 26 is used to connect the spoiler to the rear cover of the car. Specifically, the support plate 4 is provided with an annular groove 28, which is provided on the four sides of the support plate 4.

[0041] Reference Figure 3 The wing plate 101 is provided with an installation groove 5, and a support platform 6 is provided in the installation groove 5. A top block 7 is provided on the support platform 6. A storage groove 8 is provided on the lower side of the top plate 2. The top block 7 abuts against the groove wall of the storage groove 8. The top plate 2 is bonded to the support platform 6. A first glue groove 10 is provided on the support platform 6 to prevent glue from overflowing into the installation groove 5. A locking block 9 and a limiting block 12 that cooperate with the support plate 4 are provided in the storage groove 8. The locking block 9 and the limiting block 12 are used to position the support plate 4 and the top plate 2 when they are bonded. Specifically, one end of the top plate 2 is placed in the installation groove 5, and the support platform 6 is placed in the storage groove 8. Then, the glue in the first glue groove 10 on the support platform 6 is bonded to the groove wall of the storage groove 8, and the top block 7 abuts against the side wall of the storage groove 8, thereby realizing the positioning of the top plate 2.

[0042] In this embodiment, the outline of the mounting groove 5 is the same as that of the top plate 2. One side of the mounting groove 5 is connected to the outside, thereby allowing one end of the top plate 2 to extend from the main plate 1. The support platform 6 is elongated, with four top blocks 7 on each of the two long sides along its length and one top block 7 on each of the two short sides along its width. The four top blocks 7 closest to the mounting groove 5 contact the wall of the receiving groove 8 of the top block 2, while the two top blocks 7 on the two short sides contact the wall of the receiving groove 8. Three limiting blocks 12 are provided along the length of the receiving groove 8. Limiting blocks 12 are distributed on the two side walls of the storage slot 8 in the width direction, and three locking blocks 9 are provided in the storage slot 8. The three locking blocks 9 are linearly distributed. The three locking blocks 9 and the three limiting blocks 12 contact the two long side walls of the support plate 4 respectively, while the two limiting blocks 12 contact the two short side walls of the support plate 4 respectively, thereby realizing the limiting of the support plate 4 in the storage slot 8. The locking blocks 9 are provided with arc-shaped surfaces to facilitate the insertion of the support plate 4 into the storage slot 8. The specific structure of the locking blocks 9 includes a long strip-shaped horizontal column and protrusions located at both ends of the horizontal column. The protrusions contact the side walls of the support plate 4.

[0043] Reference Figure 3The mounting groove 5 is provided with a boss 27, which is bonded to the support plate 4. The boss 27 is provided with a second glue groove 11 to prevent glue overflow. In this embodiment, the boss 27 and the support plate 6 are arranged side by side, and the boss 27 is close to the opening of the mounting groove 5, which facilitates the connection between the boss 27 and the support plate 4.

[0044] Reference Figures 1-3 The edge of the wing plate 101 is provided with a pointed tip, which makes it easy for the airflow to hit the tip and flow along the surface of the wing plate 101. The end of the top plate 2 that extends outside the main plate 1 is raised upward. When the airflow moves along the bottom plate 2, it flows upward, thereby increasing the turbulence effect. The upper and lower ends of the side plate 3 are raised in the direction away from the main plate 1 to increase the turbulence effect. The airflow moves along the surface of the side plate 3, thereby the airflow spreads outward, further increasing the turbulence effect.

[0045] Furthermore, the main board 1 has a wind-breaking protrusion 102 at the front end in the vehicle length direction and a wind-breaking groove 103 at the rear end in the vehicle length direction. The setting of the wind-breaking protrusion 102 and the wind-breaking groove 103 further facilitates the guidance of airflow, and facilitates the airflow to be dispersed to the general 101 through the wind-breaking protrusion 102, so as to contact the top plate 2 and realize the turbulence of airflow.

[0046] Reference Figures 8-9 The side plate 3 is provided with a receiving groove 29 to accommodate the end face of the connecting seat 13. A guide block 30 is provided in the receiving groove 29. The guide block 30 has an arc surface on the side facing out of the receiving groove 29. The arc surface facilitates the connection between the side plate 3 and the connecting seat 13. The side plate 3 and the connecting seat 13 are bonded together. The receiving groove 29 completely covers the end of the connecting seat 13, thereby ensuring the airflow on the side of the main board 1 after the connecting seat 13 and the side plate 3 are connected. The connecting seat 13 has an inner cavity 14 at one end near the side plate 3 to reduce the weight of the connecting seat 13. A reinforcing rib 15 is provided in the inner cavity 14 to strengthen the strength of the connecting seat 13. The connecting seat 13 has a third glue groove 16 to constrain the glue and prevent glue overflow. In this embodiment, the connecting seat 13 has four reinforcing ribs. The specific shape of the embedded rib 14 is adapted to the shape of the connecting seat 13, thereby facilitating the manufacturing of the connecting seat 13.

[0047] Reference Figure 3 , 4The connector 13 has a retainer 17, and the motherboard 1 has a side groove 18 that mates with the retainer 17. The retainer 17 is inserted into the side groove 18 to further increase the stability of the connector 13 after it is connected to the motherboard 1. The retainer 17 is connected to the motherboard 1 by bolts to fix the connector 13 and the motherboard 1 after they are snapped together. The connector 13 has a positioning post 19, and the motherboard 1 has a positioning hole 20 that mates with the positioning post 19. The positioning work is achieved when the connector 13 is connected to the motherboard 1 through the cooperation of the positioning post 19 and the positioning hole 20. In this embodiment, there are two positioning posts 19, one of which is circular and the other is rectangular. The corresponding positioning hole 20 on the end face of the motherboard 1 has a circular and a rectangular cross-section, thereby ensuring that the entire connector 13 does not change shape after the two positioning posts 19 are connected to the positioning hole 20. The shape of the positioning post 19 and the positioning hole 20 makes it easy to determine the specific posture of the connector 13 during installation, thus facilitating the assembly of the connector 13. The positioning post 19 is a cross post, which increases the strength of the positioning post 19. The connector 13 is provided with a fourth glue groove 21, which contains glue. The connector 13 is also bonded to the side of the main board 1 through the glue. The connector 13 and the main body 1 are stably connected by bolts and glue. The card holder 17 is provided with reinforcing protrusions 22, which increase the strength of the card holder 17. In this embodiment, the reinforcing protrusions 22 are long strips. The two reinforcing protrusions 22 are integrally formed with the card holder 17. The two reinforcing protrusions 22 are set at both ends on the ground of the card holder 17. The card holder 17 is provided with through holes for bolts to pass through, and the side groove 18 is provided with threaded holes that mate with bolts.

[0048] Reference Figures 1-3 The main board 1 has a reserved slot 23, which facilitates the tightening of bolts during the installation of the card holder 17. A cover plate 24 is provided in the reserved slot 23 to close the reserved slot 23. The cover plate 24 is bonded to the reserved slot 23 and the reserved slot 23 is connected to the side slot 18. The reserved slot 23 has a fifth glue groove 25 to prevent glue from spreading and to achieve stable installation of the cover plate 24 in the reserved slot 23. Specifically, the inner contour of the reserved slot 23 is a parallelogram, which is adapted to the shape of the side end of the main board 1, thereby facilitating the molding of the reserved slot 23. One side of the reserved slot 23 is connected to the outside of the main board 1, thereby facilitating the installation of the cover plate 24. The side plate 18 is located in the middle of the reserved slot 23.

[0049] An assembly method for the above-mentioned spoiler, the specific assembly steps are as follows:

[0050] Step 1: Adhere the two top plates 2 to the two support plates 4 respectively and fix them with adhesive. Specifically, fill the annular adhesive groove 28 on the support plate 4 with adhesive, place the support plate 4 in the storage groove 8 of the top plate 2, and guide it into the storage groove 8 through the locking block 9 in the storage groove 8 until the side wall of the support plate 4 abuts against the lower block 12 and the groove wall of the storage groove 8 abuts against the annular adhesive groove 28. After the abutment is completed, let it stand to allow the adhesive to cure.

[0051] Step 2: Adhere the two connecting seats 13 to the two side plates 3 respectively and fix them with adhesive. Specifically, fill the third adhesive groove 16 of the connecting seat 13 with adhesive, align the receiving groove 29 of the side plate 3 with the connecting seat 13, and guide the movement of the side plate 3 through the guide block 30 in the receiving groove 29. The receiving groove 29 abuts against the end face of the connecting seat 13. After the abutment is completed, let it stand to allow the adhesive to cure.

[0052] Step 3: After connecting the top plate 2 and the support plate 4, bond the whole to the main plate 1 and cure the adhesive. Specifically, apply adhesive to the first adhesive groove 10 of the support platform 6 in the mounting groove 5 of the two wing plates 101, and apply adhesive to the second adhesive groove 11 of the boss 27. Place the top plate 2 with the support plate 4 installed into the mounting groove 5. The top plate 2 is positioned by the top block 7 on the support platform 6 and the support plate 4. The top plate 2 moves down in the mounting groove 5 until the first adhesive groove 10 contacts the storage groove 8 of the top plate 2, and the lower end of the support plate 4 at the lower end of the top plate 2 abuts against the second adhesive groove 11. After the abutment is completed, let it stand to allow the adhesive to cure.

[0053] Step 4: Apply adhesive to connector 13 and insert it into the side of motherboard 1, then tighten the bolts. Specifically, fill the fourth adhesive groove 21 on the side of connector 13 with adhesive, insert the retainer 17 on connector 13 into the side groove 18 of motherboard 1, and connect the two positioning pins 19 on connector 13 with the two positioning holes 20 on motherboard 1. The fourth adhesive groove 21 of connector 13 abuts against the side wall of motherboard 1. Pass the bolt through the through hole on retainer 17 and connect it with the threaded hole on motherboard 1. After abutting, let it stand to allow the adhesive to cure.

[0054] Step 5: Adhere the cover plate 24 into the reserved groove 23. Specifically, fill the two fifth glue tanks 23 in the reserved groove 23 with glue, place the cover plate 24 in the reserved groove 23, and let the cover plate 24 abut against the fifth glue tank 23. After the abutment is completed, let it stand to allow the glue to cure.

[0055] Step 6: Connect the two connecting brackets 26 to the bottom of the two wing plates 101 with bolts.

[0056] During the actual assembly, the installation of the connecting seat 13 and the side plate 3, and the installation of the top plate 2 and the support plate 4 are carried out simultaneously, thereby achieving the overlap of the curing time of the adhesive of the two parts, reducing the overall assembly time. After the connecting seat 13 and the main board 1 are connected, the connecting seat 13 and the main board 1 are firmly connected by bolts. The installation of the connecting seat 13 before the installation of the main board 1 and the top plate 2 facilitates the reduction of the assembly time of the entire part and increases the assembly efficiency.
