Description

Technical Field

[0001] This utility model belongs to the field of vehicle infotainment accessories technology, specifically relating to a vehicle infotainment interface that increases safety and is less prone to detachment. Background Technology

[0002] Automotive wiring harnesses are a general term for the wiring used to transmit power and signals between various components inside a modern car. They are used extensively in the car manufacturing process. At the end of the wiring harness, a plug is usually installed to connect and transfer power and signals. The device used to help connect and fix the plug is called a connector.

[0003] To ensure the proper functioning of the vehicle's infotainment system, it connects to different modules via connectors and wires to achieve various functions. In existing technologies, the two connectors are mostly plugged into each other for secure connection. However, during prolonged vehicle operation, vibrations can cause displacement between the two connectors, leading to signal interruption. Alternatively, temperature changes can cause the connectors to shrink and deform, creating gaps and short circuits that disrupt the system's operation. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle infotainment interface that is safer and less prone to detachment, in order to solve the problems mentioned in the background art, such as the possibility of displacement between the two connectors due to vibration during long-term vehicle operation, causing signal disconnection, or the possibility of gaps and short circuits caused by temperature changes due to shrinkage and deformation of the two connectors, thus affecting the normal use of the vehicle infotainment system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle interface that enhances safety and prevents detachment, comprising a connector head one and a connector head two inserted into the outside of connector head one. A spring piece is fixed to one outer wall of connector head one, and two buckles are fixed to one outer wall of the spring piece. Two slots matching the buckles are symmetrically opened on one outer wall of connector head two. Two limiting brackets are fixed to one outer wall of connector head one, and a push-pull block is movably connected between the two limiting brackets. A limiting block for supporting the spring piece is integrally formed on one outer wall of the push-pull block. Through holes are opened on both outer walls of connector head one, and a fixing sleeve is fixed in each through hole on both sides of connector head one. A clamping plate is movably connected to one side of the fixing sleeve.

[0006] In a further embodiment, both ends of the fixed sleeve are provided with movable grooves, and a connecting rod that is fixedly connected to the clamp is movably connected in the movable groove of the fixed sleeve.

[0007] In a further embodiment, a limit ring is fixed to the outer wall of the connecting rod, and a support spring for supporting the limit ring is sleeved on the outside of the connecting rod.

[0008] In a further embodiment, a pressing block is fixed to the surface of the spring piece, and a positioning frame that is movably connected to the limiting frame is fixed to the surface of the push-pull block.

[0009] In a further embodiment, guide rods are fixed to both outer walls of the push-pull block, a limit slider is fixed to one outer wall of the guide rod, and a limit groove is provided in the limit frame for the limit slider to slide.

[0010] In a further embodiment, a pulling block is fixed to the end face of the connecting rod located outside the fixed sleeve, and an arc-shaped groove is provided on one side of the outer wall of the clamping plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This new, safer, and less prone-to-detach vehicle interface allows for a secure connection between connectors. After connector one and connector two are plugged in, the spring force of the spring clip engages the two clips on the spring clip into the two slots of connector two, ensuring a stable connection between them. This prevents connector one and connector two from separating due to vibration during long-term vehicle operation, thus avoiding short circuits. It also prevents connector one and connector two from separating due to shrinkage and deformation caused by temperature changes.

[0013] With the movable push block, after the buckle is inserted into the slot of connector two, the push block drives the limit block to move, so that the limit block is inserted into the bottom of the spring piece, which restricts the position of the spring piece and prevents the spring piece from moving accidentally, thereby ensuring the firmness of the connection between connector one and connector two.

[0014] The wire is inserted into connector one, and the support spring supports the limiting ring, so that the two clamps fit against both sides of the wire, which can fix the position of the wire and prevent the wire from shaking in connector one during vehicle operation, causing the wire to fall off and affecting the normal use of the vehicle's infotainment system. This added safe and non-detachable vehicle interface not only ensures a stable connection between connector one and connector two, but also fixes the wire and prevents poor contact caused by the wire shaking.

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0022] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0023] Please see Figure 1-4This utility model provides a vehicle interface that enhances safety and prevents detachment, including a connector 1 and a connector 2 inserted into the outside of connector 1. A spring piece 3 is integrally formed on one side of the outer wall of connector 1, and two latches 4 are integrally formed on one side of the outer wall of spring piece 3. Two symmetrically formed slots matching the latches 4 are provided on one side of the outer wall of connector 2. A pressing block 5 is fixed to the surface of spring piece 3. After connector 1 and connector 2 are inserted, the two latches 4 on spring piece 3 engage under the elastic force of spring piece 3. The two slots of connector 2 ensure a stable connection between connector 1 and connector 2, preventing them from separating due to vibration during long-term vehicle operation and causing a short circuit. It also prevents connector 1 and connector 2 from shrinking and deforming due to temperature changes, which could cause them to separate. By pressing block 5 and moving spring 3 downward, the clip 4 is separated from connector 2, thus completing the disassembly of connector 1 and connector 2.

[0024] One side of the outer wall of connector 1 has two integrally formed limiting brackets. A push-pull block 7 is movably connected between the two limiting brackets 6. One side of the outer wall of the push-pull block 7 has an integrally formed limiting block 8 for supporting the spring piece 3. After the buckle 4 is inserted into the slot of connector 2, the push block drives the limiting block 8 to move, so that the limiting block 8 is inserted into the bottom of the spring piece 3, which restricts the position of the spring piece 3 and prevents the spring piece 3 from moving accidentally, thereby ensuring the firmness of the connection between connector 1 and connector 2.

[0025] The surface of the push-pull block 7 is fixed with a positioning frame 9 that is movably connected to the limiting frame 6. The positioning frame 9 can limit the position of the push-pull block 7 and ensure the stability of the push-pull block 7 when moving between the two limiting frames 6. The outer walls on both sides of the push-pull block 7 are integrally formed with guide rods 10. A limiting slider 11 is fixed on one side of the outer wall of the guide rod 10. A limiting groove for the limiting slider 11 to slide is opened in the limiting frame 6. The limiting slider 11 slides in the limiting groove of the limiting frame 6, which can limit the movement path of the push block and also prevent the push block from slipping out between the two limiting frames 6.

[0026] Both sides of the outer wall of connector 1 have through holes, and fixing sleeves 12 are fixed in the through holes on both sides of connector 1 by screws. A clamping plate 14 is movably connected to one side of the fixing sleeve 12 and is movably connected to connector 1. Both ends of the fixing sleeve 12 have moving grooves, and connecting rods 13, which are fixedly connected to clamping plates 14, are movably connected in the moving grooves of the fixing sleeve 12. The connecting rods 13 have a cuboid structure to prevent them from shaking inside the fixing sleeves 12 and to prevent clamping plates 14 from shaking inside connector 1. A limit ring 15 is fixed to the outer wall of the connecting rod 13 by screws. The outer sleeve of the connecting rod 13 is fitted with a support spring 16 for supporting the limiting ring 15. The end face of the connecting rod 13 located outside the fixed sleeve 12 is fixed with a pull block 17 by screws. An arc-shaped groove is opened on one side of the outer wall of the clamping plate 14. The arc-shaped groove on the clamping plate 14 can better fit with the wire. The wire is inserted into the connector 1 and passes through the two clamping plates 14. The support spring 16 supports the limiting ring 15, so that the two clamping plates 14 fit against both sides of the wire and fix the position of the wire. This prevents the wire from shaking in the connector 1 during vehicle operation, causing the wire to fall off and affecting the normal use of the vehicle machine.

[0029] Working principle:

[0030] This enhanced vehicle interface, designed to be safer and less prone to detachment, works by using a pull block 17 to move the connecting rod 13 and clamping plate 14. Simultaneously, the limiting ring 15 presses against the support spring 16, causing the two clamping plates 14 to move away from each other. The wire is then inserted into connector 1 and passes through the two clamping plates 14. Releasing the pull block 17 resets the support spring 16, which then supports the limiting ring 15. This allows the two clamping plates 14 to adhere to both sides of the wire, fixing its position and preventing it from swaying within connector 1 during vehicle operation, which could cause the wire to detach and affect the normal operation of the vehicle interface.

[0031] After the wire is fixed, connector 1 is inserted into connector 2, and connector 2 is connected to the vehicle's infotainment system. At the same time, spring 3 is also inserted into connector 2. Under the elastic force of spring 3, the two clips 4 on spring 3 are inserted into the two slots of connector 2, so that connector 1 and connector 2 are stably connected. By pushing the block, the limiting block 8 is moved, so that the limiting block 8 is inserted into the bottom of spring 3, which restricts the position of spring 3 and supports spring 3 to prevent spring 3 from moving accidentally, thereby ensuring the firmness of the connection between connector 1 and connector 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
