Technical Field

[0001] This utility model belongs to the field of remote control model car technology, specifically relating to a car rear wing position adjustment structure. Background Technology

[0002] A car's rear spoiler is a ducktail-shaped protrusion installed at the rear of the car's trunk lid, and is part of an aerodynamic kit. Its scientific name is "spoiler" or "spoiler panel," and it is also known as "sled panel" abroad. By changing the direction of airflow, it converts the lift of the air on the vehicle body into downward pressure, making the vehicle more in line with the ground. Especially when driving at high speed or cornering, it can effectively enhance tire grip, prevent the vehicle from drifting or skidding, and can sort out the turbulent airflow at the rear of the vehicle, reduce the low-pressure area generated by vortices, thereby reducing air resistance.

[0003] Most existing model car rear wings use an integrated design, fixed to the rear of the car with screws, 3M adhesive, or special clamps. The structure is fixed, and after installation, it is inconvenient to move and adjust the position of the rear wing relative to the bracket. The front and rear positions of the rear wing cannot be manually adjusted according to the speed of the car and the characteristics of the race track, making it difficult to adjust the center of gravity of the vehicle. This makes it less suitable and practical for professional racing users. Utility Model Content

[0004] The purpose of this invention is to provide a car rear wing position adjustment structure. By rotating and loosening the fastening bolt, the pressure exerted on the rear wing by the fixing plate is reduced, and the position of the rear wing can be adjusted by sliding, thereby increasing or decreasing the length of the car body and adjusting the center of gravity of the vehicle. This allows different users to adjust the rear wing according to the vehicle speed and the characteristics of the competition venue, selectively enhancing the vehicle's stability or flexibility, and improving its applicability and practicality.

[0005] The specific technical solution adopted by this utility model is as follows: A car rear wing position adjustment structure includes a bracket, an adjustment frame, and a rear wing, wherein the rear wing is detachably connected to the adjustment frame via a fastening bolt.

[0006] The tail fin has symmetrical through slots running through its center.

[0007] The top of the slot is provided with a fixing plate, and the bottom of the fixing plate is fixed with a pad.

[0008] The top of the adjustment frame has symmetrically formed grooves with a length shorter than the through slot.

[0009] The pad passes through the slot and fits into the groove.

[0010] The fastening bolt is located at the end of the fixing plate and the pad, and the fastening bolt is threadedly connected to the pre-set hole in the groove.

[0011] The bottom of the tail fin has an integrally formed cover groove that slides with the adjustment frame.

[0012] The adjustment frame is configured as two symmetrical pieces, connected by a long bolt threaded at one end. The adjustment frame is connected to the bracket by a short bolt threaded at the other end, and the long bolt passes through the bracket.

[0013] The technical effect achieved by this utility model is as follows: by rotating and loosening the fastening bolt, the pressure exerted on the tail wing by the fixing plate is reduced, and the position of the tail wing can be adjusted by sliding, thereby increasing or shortening the vehicle length and adjusting the vehicle's center of gravity.

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figures 1-3As shown, a car rear wing position adjustment structure includes a bracket 1, an adjustment frame 2, and a rear wing 3. The adjustment frame 2 is provided as two symmetrical ones and is threadedly connected by a long bolt 203 at one end. The adjustment frame 2 is threadedly connected to the bracket 1 by a short bolt 202 at the other end. The long bolt 203 passes through the bracket 1. The rear wing 3 is detachably connected to the adjustment frame 2 by a fastening bolt 303. A through groove 302 is symmetrically opened in the middle of the rear wing 3. A fixing plate 304 is provided at the top of the through groove 302. A pad 305 is fixed at the bottom of the fixing plate 304. A groove 201 with a length shorter than the through groove 302 is symmetrically opened at the top of the adjustment frame 2. The pad 305 passes through the through groove 302 and matches and fits into the groove 201. The fastening bolt 303 is provided at the end of the fixing plate 304 and the pad 305. The fastening bolt 303 is threadedly connected to a pre-set hole in the groove 201. A cover groove 301 that slides with the adjustment frame 2 is integrally opened at the bottom of the rear wing 3.

[0018] According to the above structure, the bracket 1 is fixed to the top of the car trunk by bolts. The adjustment bracket 2 serves as the connection between the bracket 1 and the rear spoiler 3. The adjustment bracket 2 and the rear spoiler 3 can be removed from the bracket 1 by disassembling the short bolt 202 and the long bolt 203, avoiding repeated disassembly of the bracket 1, which would damage the fixing holes of the rear cover and increase the replacement cost. The short bolt 202 and the long bolt 203 are made of M3 series bolts and nuts, and the fastening bolt 303 is made of M4 series bolts. Furthermore, when it is necessary to adjust the front and rear position of the tail wing 3, the fastening bolt 303 can be loosened by wrench to reduce the pressure applied to the tail wing 3 by the fixing plate 304, so that the pad 305 is disengaged from the groove 201. At this time, the front and rear sliding tail wing 3 can be adjusted in front and rear position. Since the cover groove 301 is embedded in the top of the adjustment frame 2, the side plates on both sides of the cover groove 301 are blocked and restricted by the adjustment frame 2, which restricts the tail wing 3 to only move back and forth, but not left and right. Furthermore, after the position adjustment is completed, press the fixing plate 304 to make the pad 305 pass through the through groove 302 and re-fit into the groove 201. Rotate the fastening bolt 303 to press the fixing plate 304 tightly so that it is attached to the top of the tail fin 3 to complete the fixation. The length of the through groove 302 is greater than that of the groove 201, which can ensure the sliding distance of the tail fin 3. If the length of the through groove 302 is too short, the pad 305 will be blocked and restricted when the fixing plate 304 is pressed down after the tail fin 3 slides. Furthermore, moving the rear wing 3 rearward increases the vehicle's length and brings the weight closer to the rear, enhancing rear wheel grip and improving stability at high speeds; moving it forward shortens the vehicle, balances the center of gravity, improves steering response, and enhances steering agility and low-speed handling.

[0019] The working principle of this utility model is as follows: the bracket 1 is fixed to the top of the car trunk by bolts. The adjustment bracket 2 serves as the connection between the bracket 1 and the rear spoiler 3. The adjustment bracket 2 and the rear spoiler 3 can be removed from the bracket 1 by disassembling the short bolt 202 and the long bolt 203, which avoids repeated disassembly of the bracket 1, which would damage the fixing holes of the rear cover and increase the replacement cost. The short bolt 202 and the long bolt 203 are made of M3 series bolts and nuts, and the fastening bolt 303 is made of M4 series bolts. Furthermore, when it is necessary to adjust the front and rear position of the tail wing 3, the fastening bolt 303 can be loosened by wrench to reduce the pressure applied to the tail wing 3 by the fixing plate 304, so that the pad 305 is disengaged from the groove 201. At this time, the front and rear sliding tail wing 3 can be adjusted in front and rear position. Since the cover groove 301 is embedded in the top of the adjustment frame 2, the side plates on both sides of the cover groove 301 are blocked and restricted by the adjustment frame 2, which restricts the tail wing 3 to only move back and forth, but not left and right. Furthermore, after the position adjustment is completed, press the fixing plate 304 to make the pad 305 pass through the through groove 302 and re-fit into the groove 201. Rotate the fastening bolt 303 to press the fixing plate 304 tightly so that it is attached to the top of the tail fin 3 to complete the fixation. The length of the through groove 302 is greater than that of the groove 201, which can ensure the sliding distance of the tail fin 3. If the length of the through groove 302 is too short, the pad 305 will be blocked and restricted when the fixing plate 304 is pressed down after the tail fin 3 slides. Furthermore, moving the rear wing 3 rearward increases the vehicle's length and brings the weight closer to the rear, enhancing rear wheel grip and improving stability at high speeds; moving it forward shortens the vehicle, balances the center of gravity, improves steering response, and enhances steering agility and low-speed handling.
