Description

Technical Field

[0001] The present invention relates to the technical field of automobile interior components, and in particular to a liquid crystal combination instrument installation structure, an installation method and a vehicle. Background Art

[0002] As the core component of vehicle information display, the LCD instrument cluster is usually integrated in the middle of the dashboard to provide the driver with key driving information such as vehicle speed, rotation speed, navigation, etc. As automobile design develops towards high-end and intelligent, suspended LCD instruments have gradually become the mainstream design due to their strong sense of technology and high space utilization. The installation structure of such instruments must take into account both mechanical reliability (such as shock resistance and anti-loosening) and visual aesthetics (such as seamless connection and hidden fixings) to avoid problems such as exposed gaps or complex structures caused by traditional fixing methods, thereby improving users' perception of interior quality.

[0003] There are currently two main ways to install LCD instruments: one is a solution that uses bolts to fix and covers. Specifically, the instrument is initially positioned using the locating pins on the dashboard, and then the instrument is fixed to the dashboard using bolts along the Z direction (vertical direction) or the X direction (horizontal direction), and finally the bolts are covered with an independent cover to hide the installation point. However, the assembly gap between the cover and the dashboard or instrument is difficult to completely eliminate, resulting in visible gaps that affect the overall aesthetics of the interior. The other is a buckle fixing solution that is fixed by directly buckling the clip with the slot on the dashboard. Although this method simplifies the assembly process, the mechanical strength of the buckle is low, and it is easy to loosen during vehicle vibration or long-term use, resulting in insufficient stability of the instrument.

[0004] In addition, the published patent CN115465098A proposes an instrument panel installation structure with an integral hat brim, which is fixed by adding wedge-shaped locking mechanisms on both sides of the instrument panel to cooperate with the instrument panel. This solution requires special tools to disassemble, and the wedge-shaped mechanism has high strength requirements for the instrument panel matching structure. If the strength is insufficient, it is easy to cause abnormal noise or functional failure risks.

[0005] Therefore, the prior art has the following technical problems:

[0006] ① Limited reliability: The anti-vibration performance of the snap-on fixing solution is poor, and it is easy to loosen after long-term use, affecting the safety of the instrument and user trust;

[0007] ② Complex structure: The wedge-shaped mechanism requires a complex locking structure to be added to the instrument panel, which results in redundant design of the instrument panel itself and places additional requirements on the strength of the mating parts of the instrument panel;

[0008] ③Inconvenient maintenance: Some solutions (such as wedge-shaped mechanisms) rely on special tools for disassembly and assembly, which increases the difficulty and cost of after-sales maintenance. Summary of the invention

[0009] In view of the deficiencies in the prior art, an object of the embodiments of the present invention is to provide a liquid crystal combination instrument installation structure with a suspension effect.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment proposes a liquid crystal combination instrument installation structure, which is used to be installed on an instrument panel 4, including an instrument screen 2, a decorative cover plate 1 and a decorative member 5; the instrument screen 2 includes a screen and a bracket 21, and the bracket 21 is arranged at the bottom of the back side of the screen;

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the front of the decorative cover plate 1 is provided with a concave platform 17, the back side of the concave platform 17 is provided with a back plate 16, a slot 15 is provided at the junction of the back plate 16 and the concave platform 17, the bracket 21 is inserted into the slot 15, the screen is connected to the back plate 16, and a set gap 18 is provided between the bottom side of the screen and the convex platform (as shown in FIG. Figure 6 The bracket 21 is located on the front side of the back panel 16, and the bracket 21 and the back panel 16 are mounted on the instrument panel 4; Figure 7 , Figure 8 , Fig. 9 As shown, the decorative member 5 is installed on the instrument panel 4 , an opening is provided in the middle of the decorative member 5 , and the decorative cover plate 1 is embedded in the opening of the decorative member 5 .

[0041] The instrument screen 2 includes a screen and a bracket 21. The bracket 21 is located at the bottom of the back side of the screen. This structural design is to support the screen and facilitate connection with the decorative cover plate 1. The design of the front concave platform 17 and the back plate 16 of the decorative cover plate 1, as well as the setting of the slot 15, allows the bracket 21 of the instrument screen 2 to be inserted into it to achieve preliminary positioning and connection. The screen is connected to the back plate 16, and there is a set gap 18 between the bottom side of the screen and the boss. The gap 18 is 2-4mm, preferably 3mm. The setting of this gap 18 is to avoid the screen and the boss directly contacting to produce abnormal noise and other problems, and it is also beneficial to the visual beauty, and the overall visual effect will not be affected by the gap 18 being too large. The bracket 21 and the back plate 16 are installed on the instrument panel 4. This is the connection method of the entire installation structure and the instrument panel 4. The decorative part 5 is installed on the instrument panel 4, and the opening in the middle allows the instrument screen 2 to be embedded, so that the instrument screen 2 can be covered and decorated, and the overall aesthetics can be improved. Under the premise of meeting the basic fixing requirements, while meeting the performance of stability, reliability, safety, etc., the visual experience of the driver and passengers is improved.

[0042] The decorative cover plate 1 is provided with two slots 15, which are respectively arranged on the left and right sides of the concave platform 17. The instrument screen 2 is provided with two brackets 21, which are respectively inserted into the two slots 15. The cooperation between the double slots 15 and the double brackets 21 enhances the installation stability and avoids the screen tilting or vibration noise caused by uneven force on one side. The slots 15 are distributed on the left and right sides of the concave platform 17, so that the brackets 21 are symmetrically embedded, ensuring the positioning accuracy of the instrument screen 2 in the horizontal direction, and dispersing the pressure of the instrument screen 2 on the decorative cover plate 1, reducing the risk of structural deformation in long-term use, and improving the reliability and stability of the installation structure.

[0043] The back plate 16 of the decorative cover plate 1 is provided with a first mounting hole 11 and a first pin hole 12, and the back of the screen is provided with a screw hole corresponding to the position of the first mounting hole 11 and a pin corresponding to the position of the first pin hole 12. After the initial positioning is achieved by the positioning pin, the screw is passed through the mounting hole to complete the fastening. This design ensures the assembly accuracy of the decorative cover plate 1 and the instrument screen 2. The pin hole positioning can prevent the component from shifting during the screw tightening process. At the same time, the distribution position of the first mounting hole 11 optimizes the connection strength and prevents the screen from cracking due to local stress concentration.

[0044] The lower side of the concave platform 17 is provided with a second mounting hole 13 and a second pin hole 14, the corresponding positions of the bracket 21 are provided with a third mounting hole and a third pin hole, and the corresponding positions of the instrument panel 4 are provided with a screw hole and a pin. The second mounting hole 13 and the second pin hole 14 on the lower side of the concave platform 17 are aligned with the third mounting hole and the third pin hole of the bracket 21, and then matched with the screw hole and the pin hole of the instrument panel 4.

[0045] This multi-level positioning design realizes the precise assembly of the instrument screen 2-decorative cover 1-instrument panel 4 layer by layer. This connection method can achieve a close connection between the various components and improve the stability of the entire installation structure. At the same time, through this connection method, the instrument assembly 3 (including the instrument screen 2 and the decorative cover 1) can be firmly fixed on the instrument panel 4, ensuring that there will be no loosening and other problems during the driving of the vehicle, ensuring the normal use and safety of the instrument.

[0046] A snap-on protrusion is provided on the back side of the decorative part 5, and a corresponding snap-on slot is provided on the instrument panel 4, and the snap-on protrusion is snapped into the slot; or, a snap-on slot is provided on the back side of the decorative part 5, and a corresponding snap-on protrusion is provided on the instrument panel 4, and the snap-on protrusion is snapped into the slot. Both schemes realize the rapid disassembly and assembly of the decorative part 5 through the snap-on structure without the need for additional tools. The elastic fit between the snap-on protrusion and the snap-on slot can compensate for the assembly gap 18 and prevent the decorative part 5 from loosening. Moreover, this connection method is also convenient for later disassembly and maintenance, and the decorative part 5 can be easily removed from the instrument panel 4. The decorative cover plate 1 adopts a reasonable matching surface and reasonable size to ensure that the visible area of ​​the decorative cover plate 1 assembled on the instrument panel 4 is minimized while ensuring that the decorative part 5 can be disassembled.

[0047] In summary, the installation structure is aimed at the floating instrument screen 2. By adding a decorative cover plate 1 and first assembling it with the instrument screen 2, the floating effect of the instrument screen 2 is achieved, and the seamless aesthetic requirements are achieved through the reasonable design of the gap 18. At the same time, the two slots 15 added at the reasonable position of the decorative cover plate 1 can avoid the two screw installation structures of the instrument screen 2, realize the screw connection of the instrument screen 2, and ensure the reliability of the screen.

[0048] Example 2

[0049] This embodiment proposes a method for installing the liquid crystal combination instrument installation structure based on the embodiment 1, comprising the following steps:

[0050] like Fig.10 As shown, first, the bracket 21 is inserted into the slot 15 of the decorative cover plate 1 to form the instrument assembly 3, then the assembly is fixed to the instrument panel 4, and finally the decorative part 5 is installed to cover the installation point. The step of pre-installing the instrument assembly 3 guides the positioning of the bracket 21 through the slot 15 to avoid the limitation of the operating space when directly assembling it to the instrument panel 4; the final installation of the decorative part 5 ensures that it is not interfered with by other parts during the assembly process, and the fixing can be completed by pressing, simplifying the process. This method realizes concealed installation through staged assembly, while reducing the dependence on the operator's operating accuracy.

[0051] Preliminary positioning is performed by passing two locating pins through the first pin hole 12 and the pin hole on the back of the screen, and the instrument screen 2 and the decorative cover plate 1 are connected by passing four screws through the first mounting hole 11 and the threaded hole on the back of the screen. Preliminary positioning is performed by passing the locating pins through the first pin hole 12 and the pin hole on the back of the screen. The locating pins can ensure the accurate relative position between the decorative cover plate 1 and the screen, and provide a precise positioning reference for subsequent connections. Then, the instrument screen 2 and the decorative cover plate 1 are connected by screws passing through the first mounting hole 11 and the threaded hole on the back of the screen. The screw connection provides a tight mechanical connection, so that the instrument screen 2 and the decorative cover plate 1 can be tightly combined to form a stable whole, ensuring the structural strength and stability of the instrument assembly 3.

[0052] In the process of assembling the decorative cover plate 1 and the instrument screen 2 to form the instrument assembly 3, ensure that there is a gap 18 between the screen of the instrument screen 2 and the concave platform 17 of the decorative cover plate 1. The existence of the gap 18 can avoid direct contact between the screen and the concave platform 17, and prevent abnormal noise due to vibration and other reasons during the driving of the vehicle. At the same time, a suitable gap 18 is also conducive to visual beauty, and the overall visual effect will not be affected due to an excessively large gap 18, nor will the screen and the concave platform 17 interfere with each other due to an excessively small gap 18, affecting the normal use of the instrument.

[0053] Preliminary positioning is performed by passing a locating pin through the third pin hole of the bracket 21, the second pin hole 14 of the decorative cover 1 and the pin hole of the instrument panel 4 in sequence, and the instrument assembly 3 is connected to the instrument panel 4 by passing a screw through the third mounting hole of the bracket 21, the second mounting hole 13 of the decorative cover 1 and the threaded hole of the instrument panel 4.

[0054] The positioning pins pass through the pin holes of the bracket 21, the decorative cover plate 1 and the instrument panel 4 in sequence, forming a three-level serial positioning, ensuring the coaxiality of the three holes, and providing an accurate positioning reference for subsequent connections. Then, the instrument assembly 3 is connected to the instrument panel 4 by screws passing through the third mounting hole of the bracket 21, the second mounting hole 13 of the decorative cover plate 1 and the threaded hole of the instrument panel 4. The screw connection provides a tight mechanical connection, so that the instrument assembly 3 can be firmly fixed on the instrument panel 4, ensuring the stability and safety of the instrument during vehicle driving.
