Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a quick-installation and removal device for a modified rear wing. Background Technology

[0002] As a common exterior modification part, the installation method of a car rear wing directly affects the user experience and the integrity of the vehicle. In the existing installation methods, the fixing of car rear wings generally relies on bolt fastening structure. The installer needs to drill mounting holes in the trunk lid of the car, then pass the bolts on the rear wing base through the mounting holes, and use nuts and washers to lock them from the inside of the trunk lid.

[0003] The above installation method requires the use of professional tools such as wrenches, and the operator needs to enter the trunk to tighten it. The whole process is complicated, time-consuming and laborious. For car owners who need to temporarily remove the rear spoiler to pass the annual vehicle inspection or enter the automatic car wash, this disassembly and assembly process is extremely inconvenient and cannot meet the needs of quick installation or removal.

[0004] In addition, cars are constantly subjected to vibrations from road bumps and huge wind resistance at high speeds during driving. These external forces repeatedly impact the connection structure of the rear wing. Traditional bolted connections are at risk of loosening under long-term use. Once the connection fails, the rear wing may fall off during driving, causing serious safety accidents. Some simple quick-release structures cannot provide enough locking force to resist this continuous dynamic load, resulting in insufficient reliability of the connection of simple quick-release structures.

[0005] Therefore, this utility model proposes a modified tail wing quick installation and removal device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome and time-consuming installation and disassembly process, insufficient connection reliability, and safety hazards in the existing technology of quick installation and disassembly devices for modified tail wings, this utility model aims to provide a modified tail wing quick installation and disassembly device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a quick installation and removal device for a modified tail wing, including a mounting plate, a mounting base fixed on the mounting plate, and a tail wing plate that can be detachably installed on the mounting base. The bottom of the tail wing plate is fixedly connected to a first clamping plate and a second sliding plate.

[0008] A rotating plate is pivotally connected to the mounting base via a fixed column. The rotating plate is used to rotate unidirectionally when the first card is inserted, in order to lock the first card.

[0009] The mounting base is also equipped with a movable locking plate 2, which forms a mechanical engagement with the rotating plate to transmit force. When the locking plate 2 is moved, it drives the rotating plate to rotate in the opposite direction to release the locking of the locking plate 1.

[0010] The quick installation and removal device for the modified tail wing also includes an anti-loosening mechanism, which includes a limiting plate with a limiting groove and a rotating plate. The second sliding plate can be inserted into the limiting groove, and the rotating plate can be rotated to lock the inserted second sliding plate. The rotating plate has a slot, and the device also includes a screw that engages with the slot thread. The screw is used to lock the rotating plate.

[0011] Preferably, the modified tail wing quick installation and removal device further includes a fixing plate and a spring. The fixing plate is fixed inside the mounting base, and the spring is disposed between the fixing plate and the locking plate to reset the locking plate after it has been moved.

[0012] Preferably, the modified tail wing quick installation and removal device further includes a sliding plate 1 and a fixing plate 2. The fixing plate 2 is fixed in the mounting base, and the sliding plate 1 serves as a guide component when the tail wing is inserted, slidingly engaging with the fixing plate 2.

[0013] Preferably, a fixed column is fixed on the mounting base, and the rotating plate is sleeved on the fixed column and rotates around the axis of the fixed column.

[0014] Preferably, the anti-loosening mechanism further includes a mounting frame and a rotating column. The mounting frame is fixed to the limiting plate or the mounting plate, and the rotating plate is pivotally mounted on the mounting frame via the rotating column.

[0015] Preferably, after the screw is screwed into the slot, the end of the screw abuts against the limiting plate, thereby locking the rotating plate at an angle.

[0016] Preferably, the anti-loosening mechanism is located at the top of the mounting plate and is separate from the main locking mechanism used to accommodate the rotating plate.

[0017] Preferably, the limiting plate and the mounting base are integrally formed or fixedly connected.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, through the cooperation of a rotating plate set in the mounting base and a locking plate on the tail wing, achieves automatic locking by pushing the rotating plate to rotate in one direction when the locking plate is inserted, and unlocking by driving the rotating plate to rotate in the opposite direction by moving the second locking plate. This structural combination solves the problem that in the prior art, modifying the tail wing requires the use of tools to tighten multiple bolts, and the installation and disassembly process is time-consuming, labor-intensive, and cumbersome. It realizes the quick installation and disassembly of the tail wing without tools, greatly improving the convenience of operation.

[0020] 2. This utility model, by adding an anti-loosening mechanism consisting of a rotating plate and locking screws independently outside the main locking mechanism, locks the sliding plate two on the rear wing plate a second time. This solves the problem that the quick-disassembly structure in the prior art has insufficient connection reliability under the action of vehicle bumps and high-speed wind resistance, and there is a risk of loosening and safety hazards. It realizes double locking of the rear wing plate, ensures a stable and reliable connection, and significantly improves driving safety. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4This utility model embodiment provides a quick installation and removal device for a modified rear wing, including a mounting plate 1 as a base, which is used to fix the entire device to the surface of the vehicle body. A mounting seat 5 is fixedly connected to the mounting plate 1. The quick installation and removal device for a modified rear wing also includes a rear wing plate 3 detachably installed on the mounting seat 5. The bottom of the rear wing plate 3 is fixedly connected to a locking plate 4 for insertion and a sliding plate 201 as an anti-loosening component. The mounting seat 5 contains a main locking mechanism for quickly locking and releasing the rear wing plate 3. The core component of the main locking mechanism is a rotating plate 12. The rotating plate 12 is pivotally connected to the mounting seat 5 through a fixing post 11. A locking plate 8 for manual release is also slidably provided on the mounting seat 5. The locking plate 8 and the rotating plate 12 form a mechanical cooperation that can transmit force, which is used to drive the rotating plate 12 to rotate in the opposite direction to release the rear wing plate 3.

[0030] To support and reset the second clamping plate 8, a first fixing plate 6 is also fixedly connected inside the mounting base 5. A spring 7 is set between the first fixing plate 6 and the second clamping plate 8. To guide the insertion process of the tail fin 3, a second fixing plate 10 is also fixedly connected to the first fixing plate 6. A first sliding plate 9 is also fixedly connected to the bottom of the tail fin 3. The first sliding plate 9 serves as a guide component when the tail fin 3 is inserted and forms a sliding fit relationship with the second fixing plate 10.

[0031] like Figure 1 and Figure 4 As shown, the modified tail wing quick installation and removal device also includes an independent anti-loosening mechanism 2. The anti-loosening mechanism 2 is set at the top of the mounting plate 1 and is used to reinforce the tail wing plate 3 after the main locking is completed. The anti-loosening mechanism 2 includes a limiting plate 202, on which a limiting groove 203 is provided for the sliding plate 201 to be inserted. The anti-loosening mechanism 2 also includes a mounting bracket 204, which is fixed to the limiting plate 202 or the mounting plate 1. A rotating column 205 is rotatably mounted on the mounting bracket 204. A rotating plate 206 is pivotally mounted on the mounting bracket 204 through the rotating column 205 and is used to lock the sliding plate 201 inserted into the limiting groove 203 after rotation. A slot 207 is provided on the rotating plate 206. The device also includes a screw 208, which is threadedly engaged with the slot 207 to lock the angle of the rotating plate 206.

[0032] Please refer to Figure 1 and Figure 3The main locking mechanism is mainly composed of a rotating plate 12, a second locking plate 8, a fixed post 11, a first fixing plate 6, a spring 7, a first sliding plate 9, and a second fixing plate 10. The fixed post 11 is vertically fixed on the base plate of the mounting seat 5. The rotating plate 12 is sleeved on the fixed post 11 and can rotate around the axis of the fixed post 11. The rotating plate 12 has a cam profile that can cooperate with the first locking plate 4 and a limiting structure that can work with the second locking plate 8. The function of the rotating plate 12 is that when the first locking plate 4 is inserted, the rotating plate 12 is pushed and rotates in one direction. After passing the locking point, it reverses and locks the first locking plate 4, thereby preventing the first locking plate 4 from being pulled out.

[0033] To enable the unlocking function, a second locking plate 8 can be slidably installed inside the mounting base 5. The working end of the second locking plate 8 forms a mechanical engagement with the limiting structure of the rotating plate 12. When the second locking plate 8 is moved, the working end of the second locking plate 8 pushes the limiting structure of the rotating plate 12, forcing the rotating plate 12 to rotate in the unlocking direction, thereby releasing the locking of the first locking plate 4. In order to enable the second locking plate 8 to automatically return to the initial position after operation, the modified tail wing quick installation and removal device also includes a first fixing plate 6 and a spring 7. The first fixing plate 6 is fixedly connected inside the mounting base 5, and the two ends of the spring 7 abut against the first fixing plate 6 and the second locking plate 8 respectively. After the second locking plate 8 is moved and released, the elastic force stored in the spring 7 pushes the second locking plate 8 back to the standby position.

[0034] Please refer to Figure 1 and Figure 3 The bottom of the tail fin 3 has a corresponding locking plate 4 with an inclined or protruding structure that can push the rotating plate 12 to rotate. During the installation of the tail fin 3, when the locking plate 4 on the tail fin 3 is inserted into the mounting base 5 along with the sliding plate 9, the inclined or protruding structure of the locking plate 4 will first contact and push the cam profile of the rotating plate 12, so that the rotating plate 12 overcomes the internal reset resistance and rotates. When the locking plate 4 is fully inserted, the rotating plate 12 rotates past the critical point and rotates back a small angle under its own reset force or gravity, thereby locking the locking surface of the rotating plate 12 behind the locked edge of the locking plate 4, thus completing the locking of the tail fin 3. In order to ensure the smoothness and stability of the insertion process, a fixing plate 2 10 is also fixed in the mounting base 5. The sliding plate 9 at the bottom of the tail fin 3 and the fixing plate 2 10 form a stable sliding fit relationship, ensuring that the tail fin 3 can be automatically locked by simply aligning and inserting during installation, and can be easily pulled out by simply moving the locking plate 2 8 during disassembly, realizing efficient and convenient installation and disassembly.

[0035] As a preferred embodiment, to ensure that card plate 28 automatically returns to the standby position after the unlocking operation, please refer to... Figure 1 and Figure 2The quick installation and removal device for the modified tail wing also includes a fixing plate 6 and a spring 7. The fixing plate 6 is fixedly connected to the inside of the mounting base 5 by welding or bolts, serving as the fixing fulcrum of the spring 7. The spring 7 is located between the fixing plate 6 and the clamping plate 8, with its two ends abutting against the wall surface of the fixing plate 6 and the thrust surface of the clamping plate 8, respectively, and always applying a reset thrust toward the locking ready position to the clamping plate 8.

[0036] As another preferred embodiment, to enhance the guiding accuracy and smooth sliding of the tail fin 3 when inserted into the mounting base 5, and to prevent misalignment or jamming during installation, please refer to... Figure 3 The quick installation and removal device for the modified tail wing also includes a sliding plate 9 and a fixing plate 10. The fixing plate 10 is fixedly connected to the fixing plate 6 to form a fixed guide rail structure. The sliding plate 9 is fixedly connected to the bottom of the tail wing plate 3 and serves as an extension guide of the clamping plate 4. The outer contour of the sliding plate 9 and the inner wall of the fixing plate 10 form a precise sliding fit relationship, guiding the tail wing plate 3 to be inserted and pulled out along a predetermined trajectory.

[0037] As another preferred embodiment, please refer to Figure 3 A cylindrical fixing post 11 is vertically and fixedly connected to the base plate of the mounting base 5. A through hole adapted to the fixing post 11 is opened in the middle of the rotating plate 12. The rotating plate 12 is sleeved on the fixing post 11 through the through hole in the middle and can rotate freely around the central axis of the fixing post 11, thereby realizing the rotation locking action of the card plate 4.

[0038] As another preferred embodiment, in order to provide a stable pivot point for the rotating plate 206 in the anti-loosening mechanism 2 and ensure smooth rotation, please refer to... Figure 4 The anti-loosening mechanism 2 also includes a mounting frame 204 and a rotating column 205. The mounting frame 204 is fixed to the side of the limiting plate 202 or the top surface of the mounting plate 1 by bolts or welding. The rotating column 205 is rotatably mounted on the mounting frame 204. The rotating plate 206 is pivotally connected to the rotating column 205 through a pivot hole, so that it can rotate around the axis of the rotating column 205 to lock or release the sliding plate 201.

[0039] As another preferred embodiment, in order to achieve final locking of the rotating plate 206 and prevent accidental rotation during vehicle movement that could lead to anti-loosening failure, please refer to... Figure 4The rotating plate 206 has a slot 207 in the form of a radial or tangential threaded hole. The screw 208 is threaded into the slot 207. When the rotating plate 206 rotates to the position where it locks the sliding plate 201, the screw 208 is tightened. The end of the screw 208 extends forward and abuts tightly against the side wall of the limiting plate 202 or a specially designed recess. The angle of the rotating plate 206 is completely fixed by the friction or axial locking force generated, thus completing the final locking.

[0040] As another preferred embodiment, please refer to Figure 1 The anti-loosening mechanism 2 is located at the top of the mounting plate 1, while the main locking mechanism for quick insertion and removal, including the rotating plate 12 and the locking plate 8, is integrated inside the mounting base 5, making the user's operation steps clearer and more orderly.

[0041] As another preferred embodiment, in order to reduce the number of parts and enhance the overall structural strength and stability of the device, and reduce the potential risks caused by loosening of the connecting parts, the limiting plate 202 and the mounting base 5 can adopt an integral molding structure or a fixed connection structure formed by welding, high-strength bolts, etc., so that the base of the main locking mechanism and the base of the anti-loosening mechanism 2 form a rigid whole, thereby improving the reliability of the entire device.

[0042] Working principle:

[0043] When installing the tail fin 3, align the locking plate 4 at the bottom of the tail fin 3 with the mounting base 5, align the sliding plate 201 with the limiting groove 203 on the limiting plate 202, and then insert the tail fin 3 as a whole. During the insertion process, the front end of the locking plate 4 will push the rotating plate 12 to rotate around the fixing post 11. When the locking plate 4 is fully in the predetermined position, the rotating plate 12 will automatically rotate and lock the rear end of the locking plate 4 due to the one-way locking structure. At this time, the initial quick fixation of the tail fin 3 is completed. To reinforce it... To connect and prevent loosening, rotate the rotating plate 206 so that the locking edge of the rotating plate 206 locks the sliding plate 201, which is already in the limiting groove 203, preventing the sliding plate 201 from moving in the pulling direction. Finally, tighten the screw 208. The screw 208 engages with the slot 207 on the rotating plate 206 through a threaded engagement, and its end extends forward and presses against the limiting plate 202, thereby completely locking the angle of the rotating plate 206. This achieves secondary locking of the tail fin 3 and ensures the long-term reliability of the connection.

[0044] When disassembling the tail fin 3, first loosen the screw 208 counterclockwise to release the angle lock on the rotating plate 206. Then rotate the rotating plate 206 in the opposite direction to disengage it from the sliding plate 201. Next, manually move the locking plate 8. After the locking plate 8 moves, it will act on the rotating plate 12, releasing the one-way locking restriction of the rotating plate 12, allowing the rotating plate 12 to rotate in the opposite direction. At this time, pull the tail fin 3 outward directly, and the locking plate 4 will smoothly disengage from the locking of the rotating plate 12. After the locking plate 8 is released, the elastic force of the spring 7 will push the locking plate 8 to automatically reset. Through the synergistic action of the main locking mechanism and the anti-loosening mechanism 2, the problems of time-consuming tail fin installation and disassembly and unstable connection in the prior art are solved.
