Abstract

The present application relates to the field of vehicle-mounted floating screen, and discloses a vehicle-mounted floating instrument device and an assembling method thereof. In the whole process of assembling the floating instrument, the installation of the machine body and the mounting bracket is connected through the inner shell and the bracket, so that the assembly stress of extruding the rear cover during installation is reduced. Moreover, the original mode of connecting the rear shell and the display module by using solid adhesive is changed into the mode of using liquid AB glue for bonding, so that the assembly stress generated during assembly can be better absorbed, the liquid AB glue will not extrude the display screen due to deformation, and the whole machine body is not fixed by using a buckle device. Through the above improvements, the display screen can be prevented from being extruded by the buckle or being extruded and deformed by the assembly stress during assembly, or the unevenness of the rear cover bonding surface itself, so that the uneven brightness can be finally avoided.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle-mounted floating screens, in particular to a vehicle-mounted floating instrument device and an assembling method thereof. BACKGROUND

[0002] With the development of the automotive electronics industry, most automobile manufacturers adopt the floating instrument scheme. Nowadays, the vehicle-mounted floating instrument is developing towards small screens and diversified appearances. In the production of traditional floating instruments, many use adhesive parts to bond the display screen and the rear cover. During the fixing process of the device, many buckle structures are often used for fixing. This will cause the deformation of the rear cover due to assembly stress during the assembly of the display screen and the rear cover, or the unevenness of the rear cover bonding surface itself is transmitted to the glass cover plate of the display module through the adhesive, or the buckles connected in the floating instrument are extruded due to the deformation of the rear cover caused by assembly stress, which will cause the entire screen to appear uneven brightness due to the extrusion of the buckles on the display screen. The use of buckles for fixing will also cause the buckles to produce abnormal noise due to friction during use. In addition, the appearance of the rear cover of the traditional floating instrument is single, and the mounting bracket of the automobile is also designed on the rear cover, so that the fixing method of the entire rear cover is not suitable for multiple vehicle models, and the adaptability is poor and not flexible. SUMMARY

[0003] To solve the above problems, the present application provides a new type of floating instrument device, which replaces the traditional adhesive with AB glue dispensing and bonding, and changes the structure for reasonable layout, thereby reducing the use of buckles, reducing the occurrence of abnormal noise, preventing the display screen from appearing uneven brightness due to extrusion caused by assembly stress, and increasing the appearance of the rear cover through hot melting, and designing the mounting bracket flexibly, so that the floating instrument can adapt to more vehicle models.

[0004] The object of the present application is achieved by the following technical solutions:

[0005] A vehicle-mounted floating instrument device, comprising: a display assembly, a circuit board, a first shell, a first AB glue bonding layer, a second shell, and a mounting bracket.

[0006] The first shell is provided with a mounting hole, the second shell is arranged inside the first shell, and the second shell is connected with the mounting bracket arranged outside the first shell through the mounting hole;

[0007] The display assembly, the circuit board, and the second shell are sequentially installed, and the circuit board is arranged in the second shell, and the display assembly is bonded to the first shell through the first AB glue bonding layer.

[0008] The instrument mainly fixes the display assembly and the circuit board on the first shell, and then fixes and connects the display assembly and the second shell through the AB glue part. When the first shell and the second shell are fixed by the AB glue, a part of the second shell passes through the first shell and is screw-fixedly connected with the rear mounting bracket. This connection mode avoids the auxiliary fixation by buckles and reduces the abnormal sound caused by the friction between the buckles. Moreover, the connection mode without buckles and with the AB glue can effectively avoid the suspension instrument during assembly, avoid the assembly stress during the pressing of the rear shell in the traditional assembly, cause the deformation of the rear shell, and cause the deformation of the buckles. Finally, the buckles extrude the display board, or the deformation of the rear cover caused by the assembly stress or the unevenness of the pasting surface of the rear cover is transmitted to the glass cover plate of the display module through the pasting part, and finally the entire screen has the problem of uneven brightness. Moreover, the protruding part of the second shell is screw-fixed with the external mounting bracket, thereby avoiding the extrusion of the mounting bracket and the first shell, i.e., the rear cover of the equipment, and reducing the occurrence of the assembly stress that causes the deformation of the rear shell.

[0014] The mounting groove is used for mounting the circuit board in the second shell and protecting the circuit board. The first cavity and the second cavity in the mounting groove are mainly used for reserving space for electrical elements on the circuit board in the second shell, so as to prevent the electrical elements from colliding with the second shell during installation. The connection between the protrusion and the groove on the inside and outside of the shell is designed as an inclined surface, so as to prevent the components from being scratched and damaged due to collision during installation.

When the two are connected, the AB adhesive is uniformly coated on the second adhesion area to form the first AB adhesive adhesion layer, and then the second shell is positioned and installed to connect the first adhesion area and the second adhesion area. This method replaces the traditional double-sided adhesive with an AB adhesive adhesion method. The liquid AB adhesive can absorb assembly stress during adhesion compared to the solid adhesive, thereby preventing device deformation and damage to components caused by extrusion between components.

[0021] In some embodiments, the first shell is a one-piece structure;

[0022] Alternatively, the first shell includes a bottom shell, a face shell, and the face shell is fixed on the bottom shell by hot melting;

[0024] The first shell has multiple properties, which can be a single appearance property formed by one-piece injection molding of the bottom shell, the face shell, and the middle frame, or a form without the middle frame, or a combination of the face shell, the middle frame, the bottom shell, and even more appearance properties. Among them, in addition to the first one-piece injection molding method, the other multiple face frame combination methods are hot melting combination. The flexible combination of the face frame and the rear cover can make the appearance property of the bottom shell more abundant, and the hot melting connection method can also make the rear shell more beautiful as a whole, and can reduce the use of buckling fixation. Compared with the use of buckling connection, the whole is more stable and there is no abnormal sound.

[0025] In some embodiments, the mounting bracket includes a bracket body, two first fixing grooves are arranged at both ends of the bracket body, and the bracket body is provided with two mounting extension parts and two clamping parts; the mounting extension parts are connected at both ends of the bracket body, and mounting screw holes are arranged at the free ends of the mounting extension parts; and the clamping parts are bent and arranged on the bracket body.

[0030] S3, fixedly connecting the display module and the mounting bracket.

[0031] The display assembly and the circuit board are fixed on the second shell through screws, and then the assembled assembly is arranged in the first shell, the first fixing block at the rear of the second shell protrudes from the rear of the first shell, and the mounting bracket is installed on the first fixing block through the first groove. In the installation process, the buckling docking step is not required, stress caused by buckling can be effectively prevented, deformation of the buckle is avoided, and finally the situation of extruding other components is avoided.

[0032] In some embodiments, in step S1, further comprising:

[0033] S11, placing the circuit board on the back plate screw column of the display assembly, and connecting the wire of the display assembly with the circuit board;

[0034] S12, placing the second shell on the circuit board, and locking and fixing the display assembly, the circuit board and the second shell through bolts.

[0038] S22, the display module is installed into the second mounting slot, and the display assembly is adhered to the first AB glue adhesion layer.

[0039] The first adhesion area on the first shell is uniformly dispensed by the dispensing machine through the dispensing limiters to form the first AB glue adhesion layer, and the second adhesion area on the display assembly is fixedly bonded through the first AB glue adhesion layer. This method replaces the traditional bonding of the bonding member with the AB glue bonding form, which can reduce the use of buckles and improve the absorption of assembly stress of the suspended instrument during assembly.

[0040] In some embodiments, it also includes applying AB glue to the mounting position of the first shell to form a second AB glue adhesion layer.

[0041] By using the AB glue film inside to fix, the buckle used for fixing can be replaced to improve the overall stability, and the tensile strength of the glue is stronger, which can absorb more assembly stress.

[0042] In some embodiments, the AB glue is a mixed liquid mixed according to a ratio of 1:10 of EL RT 776CN mixed liquid and Cat.T75 mixed liquid.

[0047] In some embodiments, in step S13, it also includes placing the first fixing slot of the mounting bracket on the first fixing block, and locking and fixing the mounting bracket and the second shell by bolts.

[0048] The mounting bracket and the suspended instrument body are connected by only the first fixing groove and the first fixing block, and the first fixing block is arranged on the second shell in the first shell, so that the direct connection of the mounting bracket and the first shell can be effectively reduced, and the first fixing groove and the first fixing block are fixed through the hole in the upper part, so that the direct connection of the mounting bracket and the first shell during assembly can be reduced, and the assembly stress generated by the extrusion of the rear shell and the mounting bracket during the traditional assembly process is weakened, so that the deformation of the rear shell caused by the assembly stress is avoided, and the extrusion of the display screen caused by the deformation of the rear shell is avoided, so that the brightness of the display screen is not uniform.

[0049] The vehicle-mounted suspended instrument device and the assembly method thereof have the following effects:

[0050] 1. Compared with the traditional suspended instrument, during the assembly of the entire suspended instrument, the installation of the machine body and the mounting bracket is connected through the inner shell and the bracket, the assembly stress caused by the extrusion of the rear cover during installation is reduced, the original connection mode of the rear shell and the display module by using the solid adhesive is changed to the connection mode by using the liquid AB glue, the assembly stress generated during assembly can be better absorbed, the liquid AB glue will not cause the problem of extrusion of the display screen caused by deformation, the liquid AB glue can also absorb the problem of unevenness of the adhesive surface of the rear shell, and the entire machine body is not fixed by using the buckle structure, and the above improvements can prevent the display screen from being extruded by the buckle or the deformation of the rear cover caused by the assembly stress or the unevenness of the adhesive surface of the rear cover, which is transmitted to the glass cover plate of the display module through the adhesive, and finally leads to the brightness unevenness of the entire screen.

[0051] 2. The second shell is directly connected with the mounting bracket, and the AB glue is used instead of the original adhesive, so that the entire suspended instrument does not need to be fixed by using the buckle, and the use of the buckle can avoid the abnormal sound of the entire suspended instrument during use.

[0052] 3. The first shell is mainly composed of a bottom shell, a middle frame and a surface shell, and the middle frame can be removed as a decorative frame during assembly, the bottom shell, the middle frame and the surface shell can be integrally injection molded in the early production, in this way, the first shell can be provided with different appearance properties by using non-heat melting materials, or the middle frame as a decorative shell can be removed, and the surface shell and the bottom shell are connected by heat melting, in this way, the design without the decorative frame has a simple appearance, or the bottom shell, the middle frame and the surface shell are not designed integrally but connected by heat melting materials, in this way, the surface processing technology such as spraying and electroplating can be used for processing, so that the appearance properties are more diverse.

[0053] 4.

[0132] Embodiment 5,

[0133] To solve the problems of the above-mentioned traditional suspension instrument device scheme, a brand-new suspension instrument device scheme is proposed, which realizes flexible and variable vehicle installation device and appearance attributes, and solves the problems of uneven display screen brightness, scratches and abnormal sound during assembly. The device composition is as shown in Figure 1 The device composition is as shown in the figure: composed of a display assembly 100, a circuit board 200, a mounting bracket 600, a first AB adhesive layer 400, and a first housing 500.

[0134] The assembly sequence of the new suspension instrument device scheme is as follows:

[0135] First process: placing the circuit board 200 on the back plate screw column 110 of the display assembly 100 and inserting the wire

[0136] Second process: placing the second housing 300 on the display assembly 100 and locking the fixing screws;

[0137] Third process: bonding the components assembled in the above process together with the first AB adhesive layer 400 and the first housing 500;

[0138] Fourth process: placing the mounting bracket 600 behind the second housing 300, and finally locking the fixing screws.

[0139] The key point of this scheme is to optimize the assembly sequence, first install the display assembly 100, the circuit board 200, and the second housing 300, and finally bond the appearance plastic component through the first AB adhesive layer 400, effectively blocking the transmission and generation of screen stress in the traditional suspension instrument scheme, and the new suspension instrument adopts the liquid AB adhesive bonding method, which can also well absorb the assembly stress, thereby preventing the display module from appearing uneven display screen brightness.

[0140] Secondly, the appearance part of the new suspension instrument device is connected by hot melting, the whole device scheme has no buckle design, and the generation of abnormal sound problems can be effectively reduced. Figure 5 As shown in the figure, the first shell 500 is composed of a bottom shell 530, a middle frame 520 and a face shell 510, and the device mode can be flexibly changed to realize one, two or three appearance attributes. For example, when the vehicle factory modeling requires only one appearance attribute, the three parts can be designed and manufactured as one part. When the vehicle factory modeling requires two appearance attributes, the middle frame 520 can be cancelled, and the bottom shell 530 and the face shell 510 can be hot melted. When the vehicle factory requires three appearance attributes, the bottom shell 530, the middle frame 520 and the face shell 510 can be hot melted.

[0141] In addition, the mounting device of the new suspension instrument is controlled by a part mounting bracket 600, and only the device of the part needs to be modified during design to match other vehicle mounting schemes, so that flexibility and variability are realized, and the compatibility of the scheme is greatly improved.
