Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automotive interior parts, and particularly relates to a liquid crystal combined instrument mounting structure, a mounting method and a vehicle. BACKGROUND

[0002] As a core component of vehicle information display, the liquid crystal combined instrument is usually integrated in the middle of the instrument panel to provide the driver with key driving information such as vehicle speed, rotating speed and navigation. With the development of high-end and intelligent design of automobiles, the suspended liquid crystal instrument gradually becomes the mainstream design due to its strong sense of technology and high space utilization rate. The mounting structure of such an instrument needs to consider both mechanical reliability (such as anti-vibration and anti-loosening) and visual aesthetics (such as seamless connection and hidden fixing), so as to avoid the problems such as exposed gap or complex structure caused by traditional fixing methods, thereby improving the user's perception of interior quality.

[0003] Currently, there are mainly two installation methods for the liquid crystal instrument: one is a scheme of bolt fixing combined with cover plate covering. Specifically, the instrument is preliminarily positioned by the positioning pin on the instrument panel, and then the instrument is fixed to the instrument panel in the Z direction (vertical direction) or X direction (horizontal direction) using a bolt, and finally the bolt is covered with an independent cover plate to hide the mounting point. However, the assembly gap between the cover plate and the instrument panel or the instrument is difficult to completely eliminate, resulting in a visible gap that affects the overall aesthetics of the interior. The other is a buckle fixing scheme, which directly buckles the buckle and the clamping groove on the instrument panel to achieve fixation. 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 screen mounting structure with an integral brim, which is fixed by adding a wedge-shaped locking mechanism on both sides of the instrument screen and cooperating with the instrument panel. This scheme needs to be disassembled with a special tool, and the wedge-shaped mechanism has a high strength requirement for the cooperation structure of the instrument panel. If the strength is insufficient, it may cause abnormal noise or functional failure risk.

[0005] Therefore, the existing technology has the following technical problems:

[0006] ① Limited reliability: the anti-vibration performance of the buckle fixing scheme is poor, and it is easy to loosen during long-term use, affecting the safety of the instrument and the user's trust;

[0007] ② Structural complexity: the wedge-shaped mechanism needs to add a complex locking structure to the instrument screen, resulting in redundant design of the instrument screen body and additional requirements for the strength of the instrument panel cooperation part;

[0037] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment proposes a liquid crystal instrument cluster mounting structure for mounting on a dashboard 4, including an instrument panel 2, a decorative cover plate 1, and a decorative component 5; the instrument panel 2 includes a screen and a bracket 21, the bracket 21 being disposed at the bottom of the back side of the screen;

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the decorative cover plate 1 has a recessed platform 17 on its front side, and a back plate 16 on its rear side. A slot 15 is provided at the junction of the back plate 16 and the recessed 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 protrusion (e.g., ...). Figure 6 (As shown); 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; as shown Figure 7 , Figure 8 , Figure 9 As shown, the decorative element 5 is installed on the dashboard 4, and the decorative element 5 has an opening in the middle, and the decorative cover plate 1 is embedded in the opening of the decorative element 5.

[0041] The instrument screen 2 comprises a screen and a support 21 located at the bottom of the back side of the screen, which is designed to support the screen and facilitate connection with the decorative cover plate 1. The design of the front recessed platform 17 and the back plate 16 of the decorative cover plate 1, as well as the setting of the slot 15, enables the support 21 of the instrument screen 2 to be inserted into the slot 15, achieving 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, which is 2-4 mm, preferably 3 mm. The gap 18 is set to avoid the problem of abnormal sound caused by direct contact between the screen and the boss, and is also conducive to visual aesthetics, without affecting the overall visual effect due to the gap 18 being too large. The support 21 and the back plate 16 are installed on the instrument panel 4, which is the connection mode 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 can embed the instrument screen 2, which can cover and decorate the instrument screen 2, and improve the overall aesthetics. Under the premise of meeting the basic fixing requirements, it meets the performance of stability, reliability, safety and other performances, and improves the visual experience of the driver and passenger.

[0042] The decorative cover plate 1 is provided with two slots 15, and the two slots 15 are respectively arranged on the left and right sides of the recessed platform 17. The instrument screen 2 is provided with two supports 21, and the two supports 21 are respectively inserted into the two slots 15. The cooperation of the double slots 15 and the double supports 21 enhances the installation stability, avoids the screen tilt or vibration abnormal sound caused by uneven force on one side. The slots 15 are distributed on the left and right sides of the recessed platform 17, so that the supports 21 are symmetrically embedded, ensuring the positioning accuracy of the instrument screen 2 in the horizontal direction, and dispersing the pressure of the weight 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 preliminary positioning is achieved by the positioning pin, the screw passes 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 assembly from shifting during screw tightening, and the distribution position of the first mounting hole 11 optimizes the connection strength, avoiding screen cracking due to local stress concentration.

[0044] The lower side of the recessed platform 17 is provided with a second mounting hole 13 and a second pin hole 14, and the support 21 is provided with a third mounting hole and a third pin hole at the corresponding position. The instrument panel 4 is provided with a screw hole and a pin hole at the corresponding position. After the second mounting hole 13 and the second pin hole 14 on the lower side of the recessed platform 17 are aligned with the third mounting hole and the third pin hole of the support 21, they are matched with the screw hole and the pin hole of the instrument panel 4.

[0045] The multi-stage positioning design realizes the precise assembly of the instrument screen 2-decorative cover plate 1-instrument panel 4 layer by layer. Such a connection mode can realize the close connection between each component and improve the stability of the entire installation structure. At the same time, through this connection mode, the instrument assembly 3 (including the instrument screen 2 and the decorative cover plate 1) can be firmly fixed on the instrument panel 4, ensuring that there is no problem such as loosening during vehicle driving, and ensuring the normal use and safety of the instrument.

[0046] The back side of the decorative part 5 is provided with a buckle protrusion, and the instrument panel 4 is provided with a corresponding clamping groove, and the buckle protrusion is clamped in the clamping groove; or the back side of the decorative part 5 is provided with a clamping groove, and the instrument panel 4 is provided with a corresponding buckle protrusion, and the buckle protrusion is clamped in the clamping groove. Both schemes realize the quick disassembly and assembly of the decorative part 5 without the need for additional tools. The elastic cooperation of the buckle protrusion and the clamping groove can compensate for the assembly gap 18 and avoid loosening of the decorative part 5. Moreover, this connection mode is also convenient for disassembly and maintenance in the later period, and the decorative part 5 can be easily disassembled from the instrument panel 4. The decorative cover plate 1 adopts a reasonable matching profile and a reasonable size to ensure that the decorative cover plate 1 on the instrument panel 4 can be minimized under the premise of disassembly of the decorative part 5.

[0047] In summary, the installation structure is aimed at the suspended instrument screen 2, and the decorative cover plate 1 is newly added and assembled with the instrument screen 2 first to realize the suspended effect of the instrument screen 2, and through the reasonable gap 18 design, the seamless and aesthetic requirements are achieved. At the same time, the two insertion grooves 15 added at a reasonable position of the decorative cover plate 1 can avoid the two screw mounting structures of the instrument screen 2, realize the screw connection of the instrument screen 2, and ensure the reliability of the screen.

[0048] Embodiment 2

[0049] The embodiment proposes an installation method based on the liquid crystal combination instrument installation structure of embodiment 1, comprising the following steps:

[0050] As shown in Figure 10 , first, insert the bracket 21 into the insertion groove 15 of the decorative cover plate 1 to form the instrument assembly 3, second, fix the assembly to the instrument panel 4, and finally install the decorative part 5 to cover the mounting point. The pre-installation of the instrument assembly 3 is guided by the insertion groove 15 to position the bracket 21, avoiding the limitation of the operation space when directly assembled to the instrument panel 4; the final installation of the decorative part 5 ensures that it is not interfered by other components during the assembly process, and the fixing can be completed by pressing, simplifying the process. This method realizes hidden installation through phased assembly, while reducing the dependence on the operation accuracy of workers.

[0051] The instrument panel 2 and the decorative cover plate 1 are connected by preliminary positioning through the positioning pin passing through the first pin hole 12 and the pin hole on the back of the screen, and four screws passing through the first mounting hole 11 and the threaded hole on the back of the screen. The instrument panel 2 and the decorative cover plate 1 are connected by preliminary positioning through the positioning pin passing through the first pin hole 12 and the pin hole on the back of the screen, and the positioning pin can ensure the relative position between the decorative cover plate 1 and the screen, and provide accurate positioning reference for subsequent connection. Then the instrument panel 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, and the screw connection provides a tight mechanical connection, so that the instrument panel 2 and the decorative cover plate 1 can be tightly combined together 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 panel 2 to form the instrument assembly 3, the screen of the instrument panel 2 and the recess 17 of the decorative cover plate 1 have a gap 18. The existence of the gap 18 can avoid direct contact between the screen and the recess 17, and prevent abnormal noise caused by vibration during vehicle driving. At the same time, appropriate gap 18 is also beneficial to the visual beauty, which will not affect the overall visual effect because the gap 18 is too large, and will not cause mutual interference between the screen and the recess 17 because the gap 18 is too small, affecting the normal use of the instrument.

[0053] The positioning pin passes through the third pin hole of the bracket 21, the second pin hole 14 of the decorative cover plate 1 and the pin hole of the instrument panel 4 in sequence to preliminarily position, and the instrument assembly 3 and the instrument panel 4 are connected by the screw 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.

[0054] The positioning pin passes through the pin holes of the bracket 21, the decorative cover plate 1 and the instrument panel 4 in sequence to form three-stage serial positioning, ensuring the coaxiality of the three hole positions, and providing accurate positioning reference for subsequent connection. Then the instrument assembly 3 and the instrument panel 4 are connected by the screw 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, and 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.
