Description
Technical Field
[0001] This utility model relates to the field of instrument panel technology, specifically to a snap-fit connection structure for a quick-release instrument panel assembly. Background Technology
[0002] In the field of automotive dashboard manufacturing, the installation and fixing method of the assembly components directly affects the production assembly efficiency and subsequent maintenance convenience. Currently, the connection between the dashboard assembly and the body structure is mostly achieved by threaded fasteners or one-time snap-fit. Among them, although the threaded connection has high reliability, the assembly process is cumbersome and time-consuming; while the traditional snap-fit structure is often simple in design and convenient to install, but lacks an effective locking and quick release mechanism.
[0003] There is currently an improved snap-fit connection scheme that attempts to balance installation efficiency and connection reliability. For example, a known instrument panel fixing structure uses a combination of insert plate and slot, and achieves initial fixing through the elastic deformation generated when the component is inserted. This scheme usually utilizes the elasticity of the plastic part itself to generate a snap-fit force, and separation is achieved by direct pulling or prying with auxiliary tools during disassembly.
[0004] However, the aforementioned existing technologies have significant limitations in practical applications. First, the snap-fit structure, which relies on material elasticity, is prone to fatigue and loosening after repeated disassembly and assembly, leading to decreased connection reliability. Second, the disassembly process often requires tools, and the operating force is difficult to control, potentially damaging components. Third, such structures lack effective secondary locking and automatic alignment functions, making them prone to abnormal noises and loosening under vehicle vibration conditions. These factors collectively restrict the maintenance efficiency and long-term reliability of the instrument panel assembly.
[0005] Based on this, this utility model designs a quick-release and detachable dashboard assembly snap-fit connection structure to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quick-disassembly and assembly snap-fit connection structure for the instrument panel assembly.
[0007] To achieve the above objectives, this utility model provides the following technical solution: A quick-release instrument panel assembly snap-fit connection structure includes a mounting base and an instrument panel body, as well as a reset mechanism, a spring-loaded mechanism, and a quick-release mechanism. A plug plate is fixedly connected to the bottom of the instrument panel body, and a first wedge block is fixedly connected to the outside of the plug plate. The mounting base has an internal cavity, and a slot is formed on the outside of the cavity. A rotating shaft is rotatably connected to the inside of the cavity, and a rotating plate is fixedly connected to the outside of the rotating shaft. A second wedge block is fixedly connected to the end of the rotating plate, and the inclined surface of the second wedge block matches the inclined surface of the first wedge block. The reset mechanism is installed on the outside of the rotating plate, the spring-loaded mechanism is installed on the inside of the cavity, and the quick-release mechanism is installed on the outside of the mounting base.
[0008] Furthermore, the slot mates with the insert plate and the first wedge block.
[0009] Furthermore, the reset mechanism includes an arc-shaped cylinder, an arc-shaped rod, a clamping plate, and a first compression spring. The arc-shaped cylinder is fixedly connected to the inner side of the cavity, the arc-shaped rod is fixedly connected to the outer side of the rotating plate, the clamping plate is fixedly connected to the end of the arc-shaped rod and slidably connected to the inner side of the arc-shaped cylinder, one end of the first compression spring is fixedly connected to the inner side of the arc-shaped cylinder, and the other end of the first compression spring is fixedly connected to the outer side of the clamping plate.
[0010] Furthermore, the card plate abuts against the inner side of the arc-shaped cylinder.
[0011] Furthermore, the rebound mechanism includes a second compression spring, a telescopic rod, and a top plate. The second compression spring and the telescopic rod are both fixedly connected to the inner bottom surface of the cavity. The top plate is fixedly connected to the top of the second compression spring and the telescopic rod, and the insert plate abuts against the upper end of the top plate.
[0012] Furthermore, the mounting base has a guide groove on its exterior, and the axes of the arc-shaped cylinder, arc-shaped rod, and guide groove all coincide with the axis of the rotating shaft.
[0013] Furthermore, the quick-release mechanism includes a slide rod and a control block. The slide rod is slidably connected to the inner side of the guide groove, and one end of the slide rod is fixedly connected to the outside of the rotating plate. The other end of the slide rod protrudes from the outer surface of the mounting base and is fixedly connected to the control block.
[0014] Furthermore, a mounting plate is fixedly connected to the bottom of the mounting base, and mounting holes are provided on the outside of the mounting plate.
[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. The quick-release and detachable instrument panel assembly snap-fit connection structure achieves automatic locking through inclined guide and elastic reset. During the insertion process, the interaction of the wedge blocks drives the rotating component to compress the spring. After passing the critical point, the spring force causes the contact surface to fit tightly to complete the self-locking. This process does not require additional operation, which significantly simplifies the installation steps. At the same time, the elastic pre-tightening force ensures a continuous and stable connection effect and effectively avoids loosening caused by vibration. 2. The quick-release instrument panel assembly features a snap-fit connection structure that combines external control with elastic ejection to achieve rapid separation. The locking state can be released by operating the external control component, while the built-in spring automatically and smoothly ejects the component. The entire disassembly process requires no tools, which not only protects the surface of the component from scratches but also greatly improves disassembly efficiency, providing great convenience for daily maintenance.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of 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 some, not all, of the embodiments of this utility model. 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.
[0020] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A quick-release instrument panel assembly snap-fit connection structure includes a mounting base 1 and an instrument panel body 2. The mounting base 1 serves as the basic carrier of the entire connection structure; its robust engineering plastic material ensures structural stability over long-term use. The instrument panel body 2, as a functional module requiring frequent disassembly and assembly, achieves a reliable connection with the mounting base 1 through this structure. It also includes a reset mechanism, a spring-loaded mechanism, and a quick-release mechanism. These three functional units work together to achieve the quick disassembly and assembly function of the connection structure. A plug plate 3 is fixedly connected to the bottom of the instrument panel body 2, serving as the main connecting element. The guide component, with its plate-like structure, provides a stable guiding function. The external of the insert plate 3 is fixedly connected to the first wedge block 4. The inclined surface design of the first wedge block 4 is a key element for achieving automatic locking. The interior of the mounting base 1 has a cavity 5, which serves as the accommodating space for each component. Its dimensions are precisely calculated to ensure that the movement of each component is not interfered with. The external of the cavity 5 has a slot 6, which serves as the guide channel for the insert plate 3. Its opening size matches the thickness of the insert plate 3. The slot 6 matches the insert plate 3 and the first wedge block 4. This precise fit ensures accurate positioning during installation.
[0021] A rotating shaft 7 is rotatably connected to the inner side of cavity 5. The rotating shaft 7 serves as the core support for the rotating component, and its axis position is carefully designed to ensure smooth rotation. A rotating plate 8 is fixedly connected to the outside of the rotating shaft 7. The rotating plate 8 acts as a force transmission medium, converting the squeezing force of the wedge block into rotational motion. A second wedge block 9 is fixedly connected to the end of the rotating plate 8. The second wedge block 9 and the first wedge block 4 form a mating pair. Their inclined surface angles are optimized to achieve smooth force transmission, and the inclined surfaces of the second wedge block 9 and the first wedge block 4 are matched. This inclined surface mating is the core mechanism for automatic locking and unlocking. A reset mechanism is installed outside the rotating plate 8. The main function of the reset mechanism is to provide restoring torque to ensure the stability of the locked state. The reset mechanism includes an arc-shaped cylinder 10, an arc-shaped rod 11, a locking plate 12, and a first compression spring 13. These components together constitute a precise... The elastic reset system consists of an arc-shaped cylinder 10 fixedly connected to the inner side of the cavity 5. The arc-shaped inner wall of the arc-shaped cylinder 10 provides a precise movement trajectory for the clamping plate 12. An arc-shaped rod 11 is fixedly connected to the outside of the rotating plate 8, accurately transmitting the rotational motion of the rotating plate 8 to the clamping plate 12. The clamping plate 12 is fixedly connected to the end of the arc-shaped rod 11. The clamping plate 12 serves as the force-bearing platform for the first compression spring 13. Its planar design ensures uniform force distribution. The clamping plate 12 is slidably connected to the inner side of the arc-shaped cylinder 10, ensuring the smoothness of the movement. One end of the first compression spring 13 is fixedly connected to the inner side of the arc-shaped cylinder 10, and the other end is fixedly connected to the outside of the clamping plate 12. The first compression spring 13 serves as an energy storage element, and its elastic coefficient is precisely calculated to provide a suitable reset force. The clamping plate 12 abuts against the inner side of the arc-shaped cylinder 10, ensuring effective force transmission.
[0022] The spring-back mechanism is installed inside the cavity 5. The main function of the spring-back mechanism is to provide initial separation force during disassembly to ensure a smooth disassembly process. The spring-back mechanism includes a second compression spring 14, a telescopic rod 15, and a top plate 16. These components together constitute a reliable elastic ejection system. The second compression spring 14 and the telescopic rod 15 are both fixedly connected to the bottom surface of the inner side of the cavity 5. The second compression spring 14 provides the main ejection force, while the telescopic rod 15 serves as a guide and limiter. The top plate 16 is fixedly connected to the top of the second compression spring 14 and the telescopic rod 15. As a component that directly contacts the insert plate 3, the planar design of the top plate 16 ensures uniform force distribution, and the insert plate 3 abuts against the upper end of the top plate 16. This contact relationship ensures the effective transmission of the ejection force.
[0023] The mounting base 1 has a guide groove 17 on its exterior. The arc trajectory of the guide groove 17 is precisely calculated to ensure that the movement trajectory of the slide rod 18 is concentric with the rotating shaft 7. The axes of the arc-shaped cylinder 10, the arc-shaped rod 11, and the guide groove 17 all coincide with the axis of the rotating shaft 7. This concentric design ensures the coordinated movement of each component. The quick-release mechanism is installed on the exterior of the mounting base 1. As a manual operation interface, the quick-release mechanism is designed with full consideration for ease of operation. The quick-release mechanism includes a slide rod 18 and a control block 19. The slide rod 18 is slidably connected to the inside of the guide groove 17. As a force transmission rod, the arc design of the slide rod 18 ensures a perfect fit with the guide groove 17. One end of the slide rod 18 is fixedly connected to the exterior of the rotating plate 8. This fixed connection ensures the effective transmission of operating force. The other end of the slide rod 18 protrudes from the outer surface of the mounting base 1 and is fixedly connected to the control block 19. The control block 19 serves as a manual operation interface, and its shape design conforms to the principles of ergonomics.
[0024] Mounting plate 20 is fixedly connected to the bottom of mounting base 1. Mounting plate 20 serves as a transition component for connection with vehicle structure. Its strength has been rigorously verified. Mounting holes 21 are provided on the outside of mounting plate 20. The size and position of mounting holes 21 are designed according to standard fixing points to ensure the reliability of installation.
[0025] In this embodiment, during installation, the insert plate 3 at the bottom of the instrument panel body 2 is aligned with the slot 6 on the mounting base 1 and a vertically downward force is applied. The insert plate 3 drives the first wedge block 4 into the cavity 5, and its inclined surface contacts the inclined surface of the second wedge block 9 at the end of the rotating plate 8 and generates compression. This inclined force forces the rotating plate 8 to rotate around the rotating shaft 7. The rotational movement drives the arc rod 11 fixed on the rotating plate 8 to deflect synchronously, causing the retaining plate 12 at the end of the arc rod 11 to slide along the inner wall of the arc cylinder 10 and compress the first compression spring 13 inside it to store elastic potential energy.
[0026] When the first wedge 4 completely passes the apex of the second wedge 9, the inclined plane extrusion force disappears, and the compressed first compression spring 13 immediately releases its energy, driving the clamping plate 12, the arc rod 11 and the rotating plate 8 assembly to rotate in the opposite direction to the initial vertical position. At this time, the lower plane of the first wedge 4 and the upper plane of the second wedge 9 form a stable contact, realizing mechanical interlocking.
[0027] At the same time, the insert plate 3 continuously presses against the top plate 16 during its descent, causing the second compression spring 14 and the telescopic rod 15 assembly below it to be compressed. The continuous upward rebound force generated by the second compression spring 14 ensures that the insert plate 3 assembly always has an upward movement tendency, effectively eliminating assembly gaps and enhancing the stability of the locking state.
[0028] During disassembly, a force is applied to the control block 19 installed outside the mounting base 1. This force is transmitted to the rotating plate 8 through the slide rod 18, forcing the rotating plate 8 to overcome the resistance of the first compression spring 13 and rotate around the rotating shaft 7. This causes the second wedge block 9 to disengage from the plane contact state with the first wedge block 4, releasing the mechanical interlock. After the lock is released, the elastic force stored in the compressed second compression spring 14 is released, and the insert plate 3 and the instrument panel body 2 are pushed upward smoothly through the top plate 16, achieving rapid and non-destructive separation. The entire disassembly and assembly process, through ingenious mechanism design, achieves rapid disassembly and assembly operations that can be completed without tools. It has the advantages of simple operation, reliable connection, and good repeatability.
[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
