Players that can be easily installed and removed not only enhance the driving experience but also increase the vehicle's usability. However, existing in-vehicle media players are prone to accidental dislodgement due to vehicle vibrations or bumps, potentially compromising driving safety.
[0004] Therefore, to address the aforementioned problems, a vehicle-mounted media player with a snap-fit structure is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a car audio player with a snap-fit structure, which aims to improve the problem that the car audio player is easily pulled out accidentally due to vehicle vibration or bumps during use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A vehicle-mounted media player with a snap-fit structure includes a central controller. An operating shell is fixedly connected to the outer front end of the central controller. An outer shell is provided on the outer rear end of the central controller. A snap-fit mechanism is provided on the outer wall of the outer shell. A positioning mechanism is provided on the rear side of the operating shell. A cable is electrically connected to the rear end of the central controller. A protective mechanism is provided on the rear side of the outer shell.
[0008] The fastening mechanism includes two plug-in blocks, with adjacent sides of the plug-in blocks fixedly connected to the two sides of the outer shell, and a pressing strip slidably connected inside the plug-in block. Multiple convex columns are fixedly connected to the outer wall of the pressing strip, and a threaded rod is rotatably connected inside the plug-in block. A drive bar is threadedly connected to the outer side of the threaded rod, and the outer inclined surface of the drive bar contacts the outer inclined surface of the pressing strip.
[0009] As a further description of the above technical solution:
[0010] The inner side of the plug block is provided with multiple oblique tooth grooves, and the inside of the plug block is provided with a locking groove;
[0011] As a further description of the above technical solution:
[0012] The plug block has a movable groove inside, and the outer side of the drive bar is slidably connected to the inside of the movable groove;
[0013] As a further description of the above technical solution:
[0014] The plug-in block has two fixedly connected internally, and the inner wall of the drive bar is slidably connected to the outer side of the two limiting rods.
[0015] As a further description of the above technical solution:
[0016] The positioning mechanism includes a positioning sleeve, one end of which is fixedly connected to the rear side of the operating shell, and the other end of which has a slot. A plurality of magnetic posts are fixedly connected to the rear side of the shell.
[0017] As a further description of the above technical solution:
[0018] The cable includes an electric wire, one end of which is electrically connected to the rear side of the central controller, and two snap-fit slots are provided on the outer side of the electric wire;
[0019] As a further description of the above technical solution:
[0020] The protective mechanism includes a rotating ring, which is rotatably connected to the rear side of the outer shell. Two extension rods are fixedly connected to the outer side of the rotating ring. A rotating rod is rotatably connected to the other end of the extension rod. A U-shaped snap-fit block is rotatably connected to the other end of the rotating rod. The adjacent ends of the U-shaped snap-fit block are detachably connected to the inside of the two snap-fit slots.
[0021] As a further description of the above technical solution:
[0022] The outer surface of the housing has two sliding grooves, and the outer side of the U-shaped snap-fit block is slidably connected to the inside of the sliding grooves.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the snap-fit position at the interface of the vehicle player is embedded into the middle cavity of the plug block, and the player is prevented from sliding out by the cooperation of the oblique tooth groove and the snap-fit groove. When it is necessary to remove the vehicle player, the drive bar moves linearly under the restriction of the limit bar by rotating the threaded rod. The oblique surface at the bottom of the drive bar presses against the oblique surface on the plug plate, causing the plug plate to deform outward and create a gap, thereby easily removing the player. This achieves stable locking of the player during bumps, avoids accidental slippage, improves driving safety, and allows for quick and non-destructive removal of the vehicle player during maintenance.
[0025] 2. In this utility model, the end of the wire is inserted into the rear structure of the central controller. The rotating ring is rotated to drive the extension rod to rotate synchronously, thereby causing the rotating rod and the U-shaped locking block to move. The two U-shaped locking blocks move towards each other under the restriction of the sliding groove, fixing the end of the wire in the locking groove, avoiding poor contact or falling off caused by vehicle bumps, and ensuring a firm electrical connection.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a car audio player with a snap-fit structure, including a central controller 1. An operating shell 2 is fixedly connected to the outer front end of the central controller 1. The operating shell 2 is used to operate the car audio player and has a sound hole. A housing 3 is provided on the outer rear end of the central controller 1. A snap-fit mechanism 4 is provided on the outer wall of the housing 3. A positioning mechanism 5 is provided on the rear side of the operating shell 2. A cable 6 is electrically connected to the rear end of the central controller 1. A protective mechanism 7 is provided on the rear side of the housing 3.
[0034] Reference Figures 1 to 3 The fastening mechanism 4 includes two plug-in blocks 401, with adjacent sides of the plug-in blocks 401 fixedly connected to both sides of the outer casing 3. Multiple oblique grooves 402 are formed on the inner side of each plug-in block 401, with the oblique direction of the grooves 402 aligned with the insertion direction of the vehicle-mounted player. The oblique grooves 402 engage with corresponding teeth in the vehicle interface (the corresponding teeth inside the vehicle interface are supported by rubber material, requiring external force to disengage in the reverse direction; the engagement of multiple sets of corresponding teeth with the oblique grooves 402 achieves a tight connection between the plug-in block 401 and the matching insert plate on the vehicle interface), creating a one-way anti-slip effect. This ensures that the player can only be locked in one direction during vibration, requiring external force to disengage in the reverse direction. A locking groove 403 is formed inside the plug-in block 401; the locking groove 403 is a transverse cavity inside the plug-in block 401 used to accommodate the matching insert plate. An extrusion strip 405 is slidably connected inside the plug-in block 401. The extrusion strip 405 is confined within the plug-in block 401 and is used to extrude the matching insert plate. Multiple convex posts 406 are fixedly connected to the outer wall of the extrusion strip 405. The convex posts 406 increase the local pressure on the matching insert plate, making it easier for the matching insert plate to detach from the plug-in block 401. A threaded rod 408 is rotatably connected inside the plug-in block 401. A drive strip 407 is threadedly connected to the outer side of the threaded rod 408. The outer inclined surface of the drive strip 407 contacts the outer inclined surface of the extrusion strip 405. When the threaded rod 408 rotates, the drive strip 407 pushes the extrusion strip 405 to move laterally, causing the insert plate to deform under pressure and create a gap, thus unlocking the plate. A movable groove 404 is formed inside the plug-in block 401. The outer side of the drive strip 407 is slidably connected to the inside of the movable groove 404, which provides space for the movement of the drive strip 407 and the extrusion strip 405.
[0035] The positioning mechanism 5 includes a positioning sleeve 501. One end of the positioning sleeve 501 is fixedly connected to the rear side of the operating housing 2, and the other end of the positioning sleeve 501 has a slot. The slot of the positioning sleeve 501 fits into the interface protrusion to form a physical limit, thereby ensuring the accurate installation position of the vehicle player while preventing the player from shifting. Multiple magnetic posts 502 are fixedly connected to the rear side of the housing 3. The magnetic posts 502 adhere to the metal parts of the vehicle interface for initial fixation.
[0036] Reference Figure 2and Figure 4 The cable 6 includes a wire 601. One end of the wire 601 is electrically connected to the rear side of the central controller 1. Two snap-fit slots 602 are provided on the outer side of the wire 601. The snap-fit slots 602 on the outer side of the end of the wire 601 are used to cooperate with the subsequent structure to form a locking structure, thereby ensuring the stability of the connection of the wire 601.
[0037] The protective mechanism 7 includes a rotating ring 701, which is rotatably connected to the rear side of the housing 3. Rotation of the rotating ring 701 enables the entire protective mechanism 7 to operate, reinforcing and protecting the connection point of the wire 601 to prevent loosening. Two extension rods 702 are fixedly connected to the outer side of the rotating ring 701, and these extension rods 702 are used to rotate the rotating ring 701. A rotating rod 703 is rotatably connected to the other end of each extension rod 702, and the rotation of the extension rod 702 drives the rotating rod 703 to rotate. A U-shaped locking block 704 is rotatably connected to the other end of the rotating rod 703. One end of the U-shaped locking block 704 is detachably connected to the inside of two locking slots 602. Rotation of the rotating rod 703 drives the U-shaped locking block 704 to move into the locking slots 602, thus forming a locking structure to ensure the stability of the wire 601 connection. The outer shell 3 has two sliding grooves 705. The outer side of the U-shaped snap block 704 is slidably connected to the inside of the sliding groove 705. The sliding groove 705 restricts the U-shaped block to move only in the axial direction, ensuring that the clamping force is concentrated on the radial direction of the wire 601 and preventing longitudinal dislodgement.
[0038] Working principle: When installing the car player, first insert the end of the wire 601 into the rear structure of the central controller 1, then rotate the rotating ring 701. The rotation of the rotating ring 701 drives the extension rod 702 to rotate synchronously. At the same time, the rotation of the extension rod 702 drives one end of the rotating rod 703 to move synchronously, thereby realizing the rotation of the rotating rod 703. The rotation of the rotating rod 703 drives the U-shaped locking block 704 to move. At the same time, due to the limiting effect of the sliding groove 705, the two U-shaped locking blocks 704 only move towards each other along the axial direction of the sliding groove 705, so that the upper end of the U-shaped locking block 704 is inserted into the locking groove 602 on the outside of the end of the wire 601 to lock it, thereby fixing the end of the wire 601 to prevent the end of the wire 601 from being loosened due to shaking when the vehicle is bumped.
[0039] Next, the entire car player is inserted into the designated position in the car. The car player is initially positioned and fixed by the cooperation of the magnetic post 502 with the car player interface and the insertion of the positioning sleeve 501. At the same time, the corresponding snap-fit position of the car player interface is inserted into the middle cavity of the plug-in block 401. The cooperation of the oblique tooth groove 402 and the engagement groove 403 makes it difficult for the car player to slide directly out of the car interface. At the same time, the insert plate matched with the plug-in block 401 presses the extrusion strip 405 into the movable groove 404, realizing the snap-fit of the entire car player. When it is necessary to remove the car player, the threaded rod 408 is rotated. The rotation of the threaded rod 408 drives the drive bar 407 to move linearly under the restriction of the two limit rods 409. The oblique surface at the bottom of the drive bar 407 presses the oblique surface on the extrusion strip 405, causing the extrusion strip 405 to move outward and generate an outward pushing force to deform the insert plate, thereby creating a gap between the insert plate and the plug-in block 401, which makes it easier to remove the entire car player.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
