[0002] The vehicle infotainment system (VIS) serves as a crucial bridge connecting the vehicle's internal and external devices. It not only expands functionality by connecting mobile phones, audio equipment, and other devices, but also allows users to access data stored in the vehicle's computer by connecting diagnostic instruments, thereby helping them understand the vehicle's operation and health status.

[0003] Deteriorating stability of the vehicle infotainment interface can lead to unstable power supply and data transmission anomalies, resulting in problems such as damage to external charging devices and interruption of file transfers. In severe cases, it can even affect the normal operation of the vehicle's electronic systems, potentially causing safety accidents. Therefore, the stability of the vehicle infotainment interface is crucial to the overall performance and user experience of the in-vehicle system. However, existing vehicle infotainment interfaces tend to deteriorate in stability over time due to loosening between the socket and connector. Therefore, we propose a new vehicle infotainment interface to improve the stability of the connection. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1) This device connects the plug and connector by connecting the hollow cylindrical shell and the hollow outer shell; then the U-shaped frame automatically resets and squeezes the clamping block, which squeezes the hollow outer shell, making the hollow outer shell and the hollow cylindrical shell fit tightly together and difficult to separate; the double insurance of normal plugging and squeezing to prevent separation makes the connection more stable; even after the vehicle interface has been running for a long time, the presence of squeezing force can still make the socket and connector stably connected.

Therefore, they should not be construed as limitations on this utility model.

[0032] Example:

[0033] Please see Figure 1-7 This utility model provides a technical solution: a stable vehicle interface, including a socket, with a connector detachably connected to the upper end of the socket. The socket includes a hollow cylindrical shell 12, with a bottom end plate 16 installed below the hollow cylindrical shell 12; the connector includes a hollow outer shell 26, with a top end plate 21 installed above the hollow outer shell 26; the upper end of the hollow cylindrical shell 12 and the lower end of the hollow outer shell 26 are inserted to complete the connection between the socket and the connector. The mating part between the hollow cylindrical shell 12 and the hollow outer shell 26 is designed as a non-circular structure to improve the torsional resistance of the connection part. The hollow cylindrical shell 12 and the bottom end plate 16 are connected by an insertion method. A snap-fit ​​female is provided on the outside of the hollow cylindrical shell 12, and a snap-fit ​​female is provided on the outside of the bottom end plate 16. The hollow cylindrical shell 12 and the bottom end plate 16 are connected by snap-fits. To prevent detachment, a one-way snap-fit ​​connection is used between the two. The bottom end plate 16 is used to connect to the vehicle end. The hollow outer shell 26 and the top sealing plate 21 are also connected by a plug-in method. A snap-on female buckle is provided on the outside of the hollow outer shell 26, and a snap-on female buckle is provided on the outside of the top sealing plate 21. The hollow outer shell 26 and the top sealing plate 21 are connected by snap-on. In order to prevent them from falling off, the two are connected by a one-way snap-on. The top sealing plate 21 is used to connect to the external device.

[0034] A wall panel 122 is provided on the inner side of the hollow cylindrical shell 12. A placement cavity is provided at the lower end of the inner cavity of the hollow cylindrical shell 12, and the placement cavity is located below the wall panel 122. A first support plate 13, a second support plate 14 and a first buffer pad 15 are placed in sequence from top to bottom on the inner side of the placement cavity, and the lower end of the first buffer pad 15 is in contact with the bottom sealing plate 16. The outer side of the first buffer pad 15 is wavy and has a certain elasticity. Through elastic support, the first buffer pad 15 is tightly attached to the bottom sealing plate 16. Similarly, the first support plate 13 and the second support plate 14 are tightly attached to each other, and the first support plate 13 is tightly attached to the hollow cylindrical shell 12, thereby ensuring the stability of the connection.

[0035] The inner cavity of the hollow outer shell 26 is provided with a second buffer pad 22, a third support plate 23, and a fourth support plate 24 from top to bottom. The upper end of the second buffer pad 22 is attached to the top sealing plate 21. The outer side of the second buffer pad 22 is also wavy and has a certain elasticity. It can be supported by elasticity to make itself fit tightly to the top sealing plate 21. Similarly, the fourth support plate 24 is tightly attached to the third support plate 23 and the hollow outer shell 26, thereby ensuring the stability of the connection.

[0036] The outer wall of the hollow outer shell 26 is provided with an outer sleeve 265, and an opening downward docking groove 266 is formed between the outer sleeve 265 and the hollow outer shell 26; when the upper end of the hollow cylindrical shell 12 is inserted into the hollow outer shell 26, the outer wall of the hollow cylindrical shell 12 is inserted into the docking groove 266, and the lower wall of the hollow outer shell 26 is inserted into the inner cavity of the hollow cylindrical shell 12; the stability of the vehicle interface connection is improved through double cooperation.

[0037] The outer wall of the outer shell 265 is movably connected to a U-shaped frame 28, and a reset shaft is provided at the connection between the U-shaped frame 28 and the outer shell 265. The reset shaft can be reset by a reset disc spring or other reset mechanism. The outer wall of the outer shell 265 is provided with a clamping block 261, which is integrally formed with the outer shell 265. The clamping block 261 is similar to a lever, with one end being a squeezing end. The squeezing end will squeeze the outer shell 265, thereby increasing the pressure between the outer shell 265 and the hollow cylindrical shell 12, thereby increasing the maximum static friction between the two and preventing the hollow outer shell 26 and the hollow cylindrical shell 12 from loosening. A hook plate is provided on one side of the extrusion end. When the U-shaped frame 28 rotates to the lower side of the hook plate, the U-shaped frame 28 can contact the hook plate. At this time, the U-shaped frame 28 has a tendency to reset, while the hook plate blocks the U-shaped frame 28, so that the U-shaped frame 28 will push the hook plate. The hook plate will push the extrusion end of the pressing block 261 to press the outer shell 265, thereby further preventing the hollow outer shell 26 from loosening with the hollow column shell 12.

[0038] Example 1:

[0039] Please see Figure 6-7A pushing groove 262 is provided on the outer wall of the outer shell 265. A pushing block 27 is slidably connected to the inner side of the pushing groove 262. The pressing end of the pressing block 261 is also provided with a release plate. When the pushing block 27 is pressed, the pushing block 27 will push the release plate, which will cause the pressing end to detach from the outer shell 265, thus facilitating the separation of the hollow cylindrical shell 12 from the hollow outer shell 26. When the release plate causes the pressing end to move, the pressing end will rotate, causing the hook plate to rotate. The rotation of the hook plate will cause its outer end to move towards the outer shell 265, thus making the U-shaped frame 28 no longer in contact with the hook plate, thereby allowing the U-shaped frame 28 to reset. In order to prevent the U-shaped frame 28 from rotating too much when resetting, limit protrusions are provided on the upper and lower sides of the outer wall of the outer shell 265. After installation, the U-shaped frame 28 is located between the upper and lower limit protrusions, which limit the rotation angle of the U-shaped frame 28.

[0040] The reset shaft is strip-shaped, with one end curved to facilitate rotation. A reset groove is formed on the side of the reset shaft near the outer casing 265, penetrating the shaft but not touching the U-shaped frame 28 body. The reset groove is V-shaped and located at the other end of the curved end of the reset shaft. A corresponding shaft groove is provided on the outer side of the outer casing 265, with a retaining groove on its outer wall. The curved end of the reset shaft is located within the shaft groove and can rotate. The corresponding end of the reset shaft in the reset groove is within the retaining groove and cannot rotate. When the U-shaped frame 28 rotates, the corresponding end of the reset shaft in the reset groove deforms, generating a force that causes the U-shaped frame 28 to tend to reset.

[0041] Example 2:

[0042] Please see Figure 3-4 6-7, A guide block is provided on the side wall of the placement cavity of the hollow cylindrical shell 12. The outer walls of the first support plate 13 and the second support plate 14 are provided with guide grooves corresponding to the guide blocks. The cooperation between the guide block and the guide groove stabilizes the first support plate 13 and the second support plate 14 and prevents them from rotating.

[0043] Similarly, guide strips are provided on the inner wall of the hollow shell 26, and grooves corresponding to the guide strips are provided on the outer sides of the third support plate 23 and the fourth support plate 24. The guide strips and the grooves cooperate to stabilize the third support plate 23 and the fourth support plate 24 and prevent them from rotating.

[0044] The first buffer pad 15 inside the hollow cylindrical shell 12 and the second buffer pad 22 inside the hollow outer shell 26 also need to be stabilized. Positioning posts are set below the first support plate 13 and the second support plate 14, and above the third support plate 23 and the fourth support plate 24. Positioning holes are opened below the second buffer pad 22, the third support plate 23 and the fourth support plate 24, and above the first buffer pad 15, the first support plate 13 and the second support plate 14. The positioning posts correspond to the positioning holes, so that the first buffer pad 15, the first support plate 13 and the second support plate 14 will not rotate relative to each other. Similarly, the second buffer pad 22, the third support plate 23 and the fourth support plate 24 will not rotate relative to each other. This avoids the internal wiring from twisting and wearing due to relative rotation. Reducing wear can also improve the stability of the vehicle interface.

[0045] Example 3:

[0046] Please see Figure 3 The hollow cylindrical shell 12 has threads on its outer side. During installation, the hollow cylindrical shell 12 needs to be fixed, and the threads facilitate this connection. A limiting ring 121 is provided on the outer side of the hollow cylindrical shell 12, located below the threads. When the hollow cylindrical shell 12 is fixed by the threads, its upper unthreaded end protrudes to facilitate docking with the hollow outer shell 26. A locking nut 11 is then screwed onto the outer side of the hollow cylindrical shell 12 to further reinforce the connection between the hollow cylindrical shell 12 and the external environment, preventing it from shaking. Furthermore, since there is a possibility of moisture seeping in through the threads of the hollow cylindrical shell 12, a sealing ring 17 is provided between the locking nut 11 and the limiting ring 121 to seal the connection and prevent water leakage.

[0047] Example 4:

[0048] Please see Figure 6-7 A mating plate 263 is provided at the lower end of the hollow outer shell 26. A sealing groove 264 is formed between the mating plate 263 and the outer shell 265, which communicates with the mating groove 266. A sealing sleeve 25 is fitted on the outside of the mating plate 263, and the sealing sleeve 25 is located inside the sealing groove 264. Through the sealing of the sealing sleeve 25, not only can it be waterproofed, but it can also enhance the friction coefficient between the hollow outer shell 26 and the hollow cylindrical shell 12, thereby increasing the maximum static friction between the two, thus stabilizing the hollow outer shell 26 and the hollow cylindrical shell 12.

[0049] Working principle: Pressing the push block 27 causes it to move downwards, squeezing open the clamping block 261. At this time, under the action of the reset shaft, the U-shaped frame 28 automatically returns to its original position, and then the plug is pulled out. During insertion, the push block 27 moves downwards, squeezing open the clamping block 261, and then the outer shell at the upper end of the hollow cylindrical shell 12 is inserted into the docking groove 266. At the same time, the docking plate 263 of the hollow outer shell 26 also enters the inner cavity of the hollow cylindrical shell 12, and the hollow cylindrical shell 12 and the hollow outer shell 26 are connected. Finally, the push block 27 is released, the clamping block 261 returns to its original position, and then the U-shaped frame 28 is rotated until it passes the push block 27. The U-shaped frame 28 is then released, and when it resets, it is blocked by the hook plate of the push block 27.
