Description

Technical Field

[0001] This invention relates to the field of plastic quick-assembly structure technology, specifically to a plastic quick-assembly structure for automobiles. Background Technology

[0002] Traditional car door panels, due to their sheet metal welding structure, are difficult to replace when damaged, requiring the replacement of the entire assembly and resulting in high repair costs. With the development of the automotive industry and the widespread use of plastic materials, traditional sheet metal welding structures will gradually be phased out. Most interior and exterior trim panels are injection molded. Interior trim parts, being plastic components, have diverse shapes and complex structures. The interior trim parts to be assembled need frequent assembly and connection with their counterparts located on the car body. To ensure a firm and reliable connection while facilitating disassembly, snap-fit ​​structures are often used to connect interior trim parts and their counterparts, making the operation simpler.

[0003] Existing traditional automotive plastic product assembly structures include screw connections, snap-fit ​​structures, and metal clips. These structures are not only difficult or impossible to disassemble, but also increase material costs, management costs, and production cycle time. Furthermore, the use of fasteners requires high precision between the two plastic parts. When plastic parts are deformed or have dimensional deviations, surface gaps or surface defects can easily occur after assembly. This not only affects the overall quality of the vehicle but also increases the difficulty of problem analysis and improvement, failing to meet people's usage needs. Summary of the Invention

[0017] This invention provides a quick-release plastic structure for automobiles, which has the following advantages:

[0018] This vehicle utilizes a plastic quick-assembly structure. Through the coordinated connection of locking blocks, fixing parts, slide rails, moving rails, tight blocks, rollers, side plates, sliding blocks, limit blocks, U-shaped grooves, trapezoidal blocks, and locking blocks, it solves the problems of slow installation, inaccurate locking, and slow installation and disassembly, resulting in significant cost waste. It allows for direct locking during operation, saving considerable time. Internal locking blocks further reduce installation and disassembly time, improving overall operating speed and efficiency, reducing operating costs, expanding its application range, and enhancing practicality. The coordinated connection of grooves, locking blocks, and the top cover facilitates easy connection between the operator and the vehicle during installation, increasing the tightness of the connection. The connection is more stable, robust, and reliable. When connected to the external protrusion via the internal connecting plate, the internal structure is more stable, increasing surface friction during operation. This provides greater stability for the operator, preventing slippage and damage to the equipment. During installation, the internal slide rails can be angled as needed for ease of use. Connecting with the internal moving track enhances stability during adjustment, allowing for faster internal track sliding and preventing damage to external components. This extends the lifespan of other internal parts. The simultaneous rotation of internal balls and rollers reduces friction while increasing movement speed, resulting in smoother force generation from the internal shaft for rapid operation. The internal triangular blocks can be adjusted by rotation and connect with the internal side plates, thereby improving installation speed, reducing operation time, and making the connection tighter. Used in conjunction with the internal side plates, it greatly improves operational safety. The connection between the fixing parts and the U-shaped groove creates a groove between the two components, facilitating direct installation and increasing tightness. Because the connection forms a matching groove, the equipment can be adjusted to meet different needs, increasing its range of applications and improving practicality. During installation, the U-shaped groove forms a channel, facilitating the installation of fixing parts. The height difference between the U-shaped groove and the trapezoidal block ensures a tighter contact during installation, increasing friction. The unequal angle formed by the U-shaped groove allows for adjustment of the U-shaped groove angle during installation. This reduces operability, makes the connection more compact, avoids complex installation, and prevents friction damage between components, reducing costs. The resulting thickness ratio reduces the internal area occupied by the friction block, making the installation and engagement tighter. The contrast with the reinforcing block reduces the pressure on the side support plates. Through the combined use of the friction block and reinforcing block, the surface strength of the equipment is higher, and it can withstand greater weight. During use, it disperses the contact force, reducing friction damage to the surface. The internal connecting plate makes the connection more secure, facilitating a tight connection between the locking block and the equipment during engagement. Its use with the internal second connecting plate makes installation faster and facilitates later disassembly and maintenance. The internal hydraulic device allows for extension.The extension mechanism, which works in conjunction with the internal top plate pillars, simplifies the operation of the locking block; simply press to extend it.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A roller 11 is arranged in parallel. A triangular block 12 is fixedly connected to the right side of the roller 11. A side plate 13 is fixedly connected to the lower part of the triangular block 12. A sliding block 14 is fixedly connected to the lower part of the side plate 13. A limit block 15 is fixedly connected to the lower left side of the sliding block 14. A fixed plate 16 is fixedly connected to the lower left side of the limit block 15. A U-shaped groove 17 is fixedly connected to the lower part of the fixed plate 16. A trapezoidal block 18 is fixedly connected to the left side of the U-shaped groove 17. A friction block 19 is fixedly connected to the lower part of the trapezoidal block 18. A reinforcing block 20 is fixedly connected to the right side of the friction block 19.

[0028] A locking block 21 is fixedly connected to the lower part of the reinforcing block 20. The locking block 21 includes a pressing block 2101, a first connecting plate 2102, a second connecting plate 2103, a fixing screw 2104, a hydraulic device 2105, a top column 2106, a top plate column 2107, and a vent hole 2108. The first connecting plate 2102 is fixedly connected to the right side of the pressing block 2101, and the second connecting plate 2103 is fixedly connected to the right side of the first connecting plate 2102. A locking device is fixedly connected to the middle of the second connecting plate 2103. A fixing screw 2104 is fixedly connected to the middle of the fixing screw 2104. A hydraulic device 2105 is fixedly connected to the right side of the hydraulic device 2105. A top column 2106 is fixedly connected to the right side of the hydraulic device 2105. A top plate column 2107 is fixedly connected to the right side of the top column 2106. A vent 2108 is fixedly connected to the right side of the top plate column 2107. A frame 22 is fixedly connected to the bottom of the locking block 21. A heat dissipation vent 23 is fixedly connected to the middle of the frame 22.

[0029] In this embodiment, the groove 1 and the locking block 2 form a detachable structure, and the length ratio of the upper cover plate 3 to the locking block 2 is 1:1. Through the cooperation and connection of the groove 1, the locking block 2 and the upper cover plate 3, it is easy for the operator to connect with the vehicle during installation, which can increase the tightness of the connection and make the connection more stable, firm and reliable.

[0030] In this embodiment, the connecting plate 4 and the protrusion 5 are connected by a snap-fit ​​mechanism, and the protrusion 5 and the fixing part 6 form an integral structure. When the internal connecting plate 4 is connected to the external protrusion 5, the internal structure is more stable, and the friction of the contact surface is greater during operation, so that the operator can operate more stably and avoid slipping and causing damage to the equipment.

[0031] In this embodiment, the slide rail 7 and the moving track 8 form a sliding structure. There is only one moving track 8, and the moving track 8 and the tight block 9 form a detachable structure. During installation, the internal slide rail 7 can be adjusted at an angle as needed to facilitate installation and use. At the same time, it connects with the internal moving track 8, making the adjustment more stable and allowing the internal track to slide faster. This also avoids damage to externally connected components and can improve the service life of other internal components.

[0032] In this embodiment, the ball 10 and the roller 11 form a rotating structure. There are multiple balls 10, and the central axes of the balls 10 and the roller 11 coincide. By rotating the internal balls 10 and roller 11 simultaneously, the friction is reduced while the moving speed is increased, making the force generated by the internal shaft more stable, so as to facilitate rapid adjustment.

[0033] In this embodiment, the triangular block 12 is connected to the side plate 13 by welding, and the side plate 13 is connected to the sliding block 14 by snap-fit. The internal triangular block 12 can be adjusted by rotation to connect with the internal side plate 13, thereby improving the installation speed, reducing the operation time, making the connection tighter, and greatly improving the operation safety when used with the internal side plate 13.

[0034] In this embodiment, the fixed part 6 and the U-shaped groove 17 form an upper boss structure. The fixed plate 16 is perpendicular to the movement trajectory of the movable part, and the fixed plate 16 and the U-shaped groove 17 form a matching limiting groove. The fixed part 6 and the U-shaped groove 17 are connected, and the two parts form a concave-convex groove, which facilitates direct installation and increases tightness. Since the connection forms a matching groove, the equipment can be adjusted according to different needs, increasing the range of use and improving practicality.

[0035] In this embodiment, the U-shaped groove 17 of the fixing part 6 forms a boss structure with a height-to-width ratio of 3.8:2. The trapezoidal block 18 has a trapezoidal structure with a height-to-thickness ratio of 2.5:2 and an obtuse angle. The quick-release side has an angle 20 degrees larger than the stop side. The trapezoidal block 18 and the fixing part 6 form a rotating structure for assembly. During installation, the U-shaped groove 17 forms a groove, which facilitates the installation of the fixing part 6. The height difference between the U-shaped groove 17 and the trapezoidal block 18 facilitates tighter contact during installation, increases friction, and forms an unequal angle with the connecting U-shaped groove 17. This allows for adjustment of the angle of the U-shaped groove 17 during installation, thereby reducing operability, making the connection more compact, avoiding complex installation, preventing friction damage between components, and reducing costs.

[0036] In this embodiment, the friction block 19 and the reinforcing block 20 are connected by welding, and the thickness ratio of the reinforcing block 20 to the friction block 19 is 2:1. This thickness ratio reduces the internal area occupied by the friction block 19, making the installation and engagement tighter. In contrast to the reinforcing block 20, it reduces the pressure on the support plates on both sides. Through the combined use of the friction block 19 and the reinforcing block 20, the surface strength of the equipment is higher, and it can bear a greater weight. During use, the contact force can be dispersed, reducing frictional damage to the surface.

[0037] In this embodiment, the pressing block 2101 and the first connecting plate 2102 are connected by a snap-fit ​​mechanism. The first connecting plate 2102 is a single plate, and the second connecting plate 2103 is symmetrical about the horizontal center line of the first connecting plate 2102. The connection is made more secure by the internal connecting plate, which makes it easier for the pressing block 21 to be tightly connected to the equipment when snapped in, and to cooperate with the internal second connecting plate 2103. This makes the installation faster and facilitates disassembly and maintenance in the future.

[0038] In this embodiment, the hydraulic device 2105 and the top column 2106 form a telescopic structure, and the top column 2106 and the top plate column 2107 are connected by a snap-fit. The internal hydraulic device 2105 can be extended to cooperate with the internal top plate column 2107 to extend, making the overall operation of the locking block 21 simpler. It can be extended by simply pressing.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] When in use, first use the bottom locking block 21 for positioning and fixing, then adjust the use according to the screw fastening components connected to the internal slide rail 7, adjust according to the needs of the installed equipment, then align and connect with the equipment through the top locking block 2, and use external force to directly lock it in place, adjust the angle through the U-shaped groove 17 and trapezoidal block 18 connected in the middle, and fix it with the reinforcing block 20, and the operation can be completed.

[0041] In summary, this vehicle-mounted plastic quick-release structure is simpler to operate, and the locking mechanism is faster during installation, saving a significant amount of time. It also makes the internal connections tighter, reducing equipment cost waste and facilitating installation and disassembly.
