Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, specifically a fixing device for a full LCD instrument combination. Background Technology

[0002] The instrument cluster is the core interface for drivers to interact with their vehicles. It displays operating parameters such as vehicle speed, mileage, fuel level, and RPM, as well as fault information. It is equipped with various indicator lights, including light signals and fault warnings. Modern instrument clusters use a modular design, integrating components such as microcontrollers (MCUs), stepper motors, circuit boards, and alarm buzzers.

[0003] Full LCD instrument clusters are widely used in modern automobiles due to their advantages such as rich display information and customizable interface. Currently, most full LCD instrument clusters are fixed by direct screw fastening, which presents problems of inconvenience in disassembly and assembly, requiring the removal of multiple screws. Repair and replacement are also cumbersome, time-consuming, and inconvenient to use. Therefore, a fixing device for full LCD instrument clusters is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for a full LCD instrument cluster, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for a full LCD instrument combination, comprising a mounting frame, wherein fixing blocks are uniformly fixedly connected to the rear side of the inner sidewall of the mounting frame, two positioning strips are symmetrically fixedly connected to the side of the inner sidewall of the mounting frame near the fixing blocks, two T-shaped slots are symmetrically opened on the front surface of the mounting frame, a blind groove is opened on one side of the inner sidewall of the T-shaped slot, a T-shaped insert is inserted into the inner sidewall of the T-shaped slot, a pressure strip is fixedly connected to one side of the T-shaped insert, a wedge plate is fixedly connected to the other side of the T-shaped insert, a sliding plate is fixedly connected to the inner sidewall of the blind groove, a sliding sleeve is slidably connected to the outer sidewall of the sliding plate, two springs are symmetrically fixedly connected between the inner sidewall of the sliding sleeve and the outer sidewall of the sliding plate, a retaining tooth is fixedly connected to the side of the sliding sleeve away from the sliding plate, a threaded cylinder is fixedly connected to the front surface of the sliding sleeve, a threaded rod is threadedly connected to the inner sidewall of the threaded cylinder, and a rotating block is fixedly connected to the front end of the threaded rod.

[0006] As a further preferred embodiment of this technical solution, the front surface of the fixing block is provided with fixing holes.

[0007] As a further preferred embodiment of this technical solution: a silicone strip is adhered to the front surface of the positioning strip.

[0008] As a further preferred embodiment of this technical solution: a rubber strip is adhered to the rear surface of the pressure strip.

[0009] As a further preferred embodiment of this technical solution: a rubber ring is bonded to the rear surface of the rotating block.

[0010] As a further preferred embodiment of this technical solution: the outer side wall of the rotating block is uniformly provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In operation, this invention uses external screws to lock the fixing block onto the car's dashboard. The full LCD instrument cluster is placed into the mounting frame to align with the positioning strip. The T-shaped insert is inserted into the T-slot and pressed down. The wedge plate moves backward along with the T-shaped insert. During this process, the wedge plate slides over and presses against the retaining teeth. The spring repeatedly extends and retracts until the pressure strip presses against the edge of the instrument cluster's dial. Under the spring's elasticity, the retaining teeth are pushed to lock the wedge plate, locking the wedge plate, T-shaped insert, and pressure strip. At this point, the pressure of the pressure strip allows for quick installation and fixation of the instrument cluster. Tightening the threaded rod causes the rotating block to press against the front surface of the mounting frame. The friction between the rotating block and the mounting frame locks the rotating block, thereby locking the retaining teeth and preventing them from loosening. When the instrument cluster needs to be disassembled, slightly loosening the threaded rod and moving the rotating block moves the retaining teeth away from the wedge plate, releasing the lock on the T-shaped insert and pressure strip. The instrument cluster can then be quickly removed by removing the T-shaped insert. The operation is simple and the disassembly and assembly are quick, providing convenience for users.

A threaded cylinder 16 is fixedly connected to the front surface of the sliding sleeve 11. A threaded rod 17 is threadedly connected to the inner wall of the threaded cylinder 16. A rotating block 18 is fixedly connected to the front end of the threaded rod 17. The fixing block 2 is locked to the dashboard of the car by means of external screws. Place the full LCD instrument cluster into the mounting frame 1, ensuring it aligns with the positioning strip 4. Insert the T-shaped insert 6 into the T-shaped slot 5 and press it down. The wedge plate 9 moves backward along with the T-shaped insert 6. During this process, the wedge plate 9 slides past and presses against the retaining teeth 13. The spring 12 repeatedly extends and retracts until the pressure strip 8 presses firmly against the edge of the instrument cluster's dial. Under the elastic force of the spring 12, the retaining teeth 13 are pushed to lock the wedge plate 9, thus locking the wedge plate 9, the T-shaped insert 6, and the pressure strip 8. At this point, the instrument cluster can be fully mounted using the clamping force of the pressure strip 8. The instrument can be quickly installed and fixed by tightening the threaded rod 17 so that the rotating block 18 presses against the front surface of the mounting frame 1. The rotating block 18 is locked by the friction between the rotating block 18 and the mounting frame 1, thereby locking the retaining tooth 13 and preventing it from loosening. When it is necessary to disassemble the instrument, the threaded rod 17 is loosened slightly and the rotating block 18 is moved to move the retaining tooth 13 away from the wedge plate 9, which can release the lock on the T-shaped insert 6 and the pressure strip 8. The instrument can be quickly removed by removing the T-shaped insert 6. The operation is simple and the disassembly and assembly are quick, bringing convenience to the user.

[0025] In this embodiment, specifically: a fixing hole 3 is provided on the front surface of the fixing block 2; so that the fixing block 2 can be locked to the car dashboard by means of an external screw in conjunction with the fixing hole 3.

[0026] In this embodiment, specifically: a silicone strip 14 is adhered to the front surface of the positioning strip 4; the silicone strip 14 can absorb the vibration force during the vehicle's operation and protect the instrument cluster.

[0027] In this embodiment, specifically: a rubber strip 15 is bonded to the rear surface of the pressure strip 8; the softness of the rubber strip 15 can prevent damage to the surface of the instrument combination.

[0028] In this embodiment, specifically: a rubber ring 19 is bonded to the rear surface of the rotating block 18; the rubber ring 19 can increase the friction between the rotating block 18 and the mounting frame 1.

[0029] In this embodiment, specifically: anti-slip textures 20 are evenly provided on the outer side wall of the rotating block 18; this facilitates the rotation of the rotating block 18 and reduces slippage.

[0030] The working principle of this utility model is as follows: The fixing block 2 is locked to the dashboard of the car using external screws. The full LCD instrument cluster is placed in the mounting frame 1 to fit against the positioning strip 4. The T-shaped insert 6 is inserted into the T-shaped slot 5 and pressed down. The wedge plate 9 moves backward along with the T-shaped insert 6. During this process, the wedge plate 9 slides past and presses against the retaining teeth 13. The spring 12 repeatedly extends and retracts until the pressure strip 8 presses against the edge of the instrument cluster dial. Under the elastic force of the spring 12, the retaining teeth 13 are pushed to lock the wedge plate 9, thus locking the wedge plate 9, the T-shaped insert 6, and the pressure strip 8. At this time, the... The clamping force of the pressure bar 8 enables the quick installation and fixation of the instrument cluster. Tightening the threaded rod 17 causes the rotating block 18 to press against the front surface of the mounting frame 1. The friction between the rotating block 18 and the mounting frame 1 locks the rotating block 18, thereby locking the retaining tooth 13 and preventing it from loosening. When it is necessary to disassemble the instrument cluster, slightly loosening the threaded rod 17 and moving the rotating block 18 will move the retaining tooth 13 away from the wedge plate 9, which will release the lock on the T-shaped insert 6 and the pressure bar 8. The instrument cluster can be quickly removed by removing the T-shaped insert 6. The operation is simple and the disassembly and assembly are quick, bringing convenience to the user.
