[0040] like Figure 1 and Figure 2 In some embodiments, the instrument panel assembly includes a display module 100. Exemplarily, the display module 100 may be a touch liquid crystal module (TLCM). The display module 100 may include a cover plate 110 (e.g., a glass cover plate) and a display panel 130. The cover plate 110 may be bonded to the light-emitting side of the display panel 130 via an optical adhesive layer (e.g., OCA or OCR). The side of the cover plate 110 connected to the display panel 130 is also connected to a back plate 120. The back plate 120 includes a bottom plate 121 and side plates 122 arranged along the circumferential edge of the bottom plate 121. The side plates 122 and the bottom plate 121 are combined to form a receiving cavity of the back plate 120. At least part of the display panel 130 may be located in the receiving cavity of the back plate 120.

[0041] When the display panel 130 is a liquid crystal display panel, a backlight unit for providing backlight to the liquid crystal display panel may be further disposed in the receiving cavity of the back plate 120. For example, the backlight unit may include a backlight source, a light guide plate, an optical film layer, and the like.

[0042] In order to install the display device on the instrument panel frame of the vehicle, the instrument panel assembly further includes a housing 200 for installing the display module 100, such as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The housing 200 includes a front housing 210 and a rear housing 220. For example, the front housing 210 and the rear housing 220 can be provided with buckles that can cooperate with each other to enable the front housing 210 and the rear housing 220 to be clamped together. In order to install the display module 100, the rear housing 220 is provided with a first accommodating space 221. The front housing 210 is provided with a first accommodating space 221 in the thickness direction (such as Figure 5 and Figure 6 A through-mounting hole 211 is provided on the front housing 210 (in the Z direction), and the through-mounting hole 211 communicates with the first accommodating space 221. During assembly, an adhesive layer 300 (e.g., a VHB layer) can be provided on a side of the front housing 210 away from the rear housing 220 (hereinafter referred to as the exposed side) and surrounding the through-mounting hole 211. The back panel 120 of the display module 100 passes through the through-mounting hole 211 from the exposed side of the front housing 210. The cover plate 110 of the display module 100 is bonded to the front housing 210 via the adhesive layer 300, and a pressure-maintaining action is performed to ensure full contact between the front housing 210 and the cover plate 110 of the display module 100.

[0043] After the front shell 210 and the cover plate 110 are bonded together, the rear shell 220 is clamped to the front shell 210 to pre-fix the front shell 210 and the rear shell 220. At this time, at least a portion of the back plate 120 passing through the mounting hole 211 can be located in the first receiving space 221 of the rear shell 220.

[0044] After the above pre-fixation is completed, multiple screws are installed from the side of the rear shell 220 away from the front shell 210. The screws pass through the rear shell 220 and are threadedly connected to the bottom plate 121 of the back plate 120, thereby completing the assembly of the display module 100 and the outer shell 200.

[0045] The housing 200 may be a sheet metal part, a die-cast part or a plastic part.

[0046] Due to the limitations of processing methods, sheet metal parts can only correspond to limited shapes and structures, and it is difficult to meet the special needs of most customers on the market for shapes and structures.

[0047] Die castings are formed by pouring. Although they can be flexibly adapted in terms of shape, they also have two limiting factors. First, die castings are heavy, and it is difficult for die castings with larger shapes to meet the more stringent weight requirements. Second, die castings are expensive, and the cost of remolding is also high.

[0048] Compared to sheet metal, plastic parts can be formed into a variety of shapes and structures; compared to die-cast parts, plastic parts are weight-controlled and cost-effective. Compared to sheet metal and die-cast parts, plastic parts have lower structural strength. However, for structural parts with wide shapes and large support surfaces, the structural strength of plastic parts made of PC and ABS can generally meet user requirements.

[0049] Combine Figure 3 、 Figure 4 and Figure 5 To ensure that the housing 200 matches the mounting structure of the vehicle instrument panel frame and the external structure of the display module 100, the housing 200 is designed to be relatively complex. Furthermore, vehicle manufacturers have strict weight requirements for instrument panel assemblies. To meet these requirements, in some embodiments, the housing 200 of the instrument panel assembly is made of plastic.

[0050] After the instrument panel assembly is installed on the vehicle's instrument panel frame, part of the front shell 210 will be directly displayed to the user as an exterior part. Based on the consideration of aesthetics, the front shell 210 adopts a narrow frame design. Figure 3 and Figure 5 , along the first direction (such as Figure 3 and Figure 5 The edge of the mounting hole 211 and the edge of the front shell 210 define a front shell frame 212. Figure 3 and Figure 5 In the direction of , the front shell frame 212 is located above and below the display module 100.

[0051] When the housing 200 is a plastic part, the width of the front housing frame 212 is narrow and its own strength is low. Although the front housing frame 212 is connected to the cover plate 110 through the adhesive layer 300, the narrow width of the front housing frame 212 makes the layout space of the adhesive layer 300 limited, and the adhesive force provided by the adhesive layer 300 to the front housing frame 212 is also weak. Figure 5 and Figure 6 It can be seen that there is no structure inside the housing 200 that can provide support for the front housing frame 212. Figure 6 When an external force F is applied to the front shell frame 212, the adhesive layer 300 between the front shell frame 212 and the cover plate 110 is likely to fail under the action of the external force F, causing the front shell frame 212 to bend toward the rear shell 220, affecting product quality.

[0052] In order to solve the above problem, one way is to increase the viscosity of the adhesive layer 300 so that the adhesive layer 300 can generate a greater force on the front shell frame 212.

[0053] However, firstly, since the layout space of the adhesive layer 300 at the front shell frame 212 is relatively small, it is difficult to make the force generated by the adhesive layer 300 sufficient to counteract the external force F; secondly, there are many factors that affect the viscous force generated by the adhesive layer 300. For example, since the front shell 210 is an exterior part, its surface will be painted. After actual measurement, it was found that the dyne value of the surface treated with paint will decrease, which will make the adhesive layer 300 more likely to fail; for example, if the adhesive layer 300 is contaminated by dust and debris during the layout, bonding and pressure holding process, it will also make the adhesive layer 300 more likely to fail. For the above factors, although the area on the front shell 210 where the adhesive layer 300 is laid can be covered by a jig so that the surface of the area is not covered by paint, and the surface of the front shell 210 where the adhesive layer 300 is laid can be kept clean by standardizing the gluing operation (for example, wiping the surface of the front shell 210 in advance), preventing the adhesive layer 300 from being contaminated, and ensuring sufficient pressure holding time. However, the above method places a great challenge on the process side, and it is difficult to ensure stable product quality after mass production.

[0054] Another way to solve the above problem is to increase the thickness of the front shell frame 212 so that the front shell frame 212 itself has greater compressive strength.

[0055] However, firstly, increasing the material thickness will cause stress marks to appear on the front shell 210, affecting the appearance of the front shell 210; secondly, the shrinkage and deformation of the thicker front shell 210 during the formation process will also be aggravated; finally, due to the space limitation of the dashboard, the space for increasing the thickness of the front shell 210 is also relatively small. If the external force F is large, the front shell frame 212 still has the risk of detaching from the adhesive layer 300 and loosening.

[0056] In order to better solve the above problems, Figure 7 and Figure 8 As shown, this embodiment provides a display device, including: a rear shell 220, provided with a first accommodating space 221; a front shell 210, connected to the rear shell 220, and extending along the thickness direction of the front shell 210 (such as Figure 8 A mounting through hole 211 is provided through the front shell 210 along the Z direction, and the mounting through hole 211 is connected to the first accommodating space 221; along the first direction, a front shell frame 212 is defined between the edge of the mounting through hole 211 and the edge of the front shell 210, and the first direction is perpendicular to the thickness direction of the front shell 210; the display module 100 includes a stacked cover plate 110 and a back plate 120 along the thickness direction of the front shell 210; the cover plate 110 is connected to the side of the front shell 210 away from the rear shell 220, and at least a part of the back plate 120 is installed in the first accommodating space 221 through the mounting through hole 211; the support structure 400 is respectively connected to the back plate 120 and the front shell frame 212, and the support structure 400 is used to support the front shell frame 212 at least along the thickness direction of the front shell 210.

[0057] Exemplarily, the support structure 400 may be located between the back plate 120 and the front shell frame 212 , or located on a side of the front shell frame 212 close to the rear shell 220 .

[0058] Illustratively, along the thickness direction of the front shell 210, the orthographic projection of the cover plate 110 on the surface of the front shell 210 completely covers the mounting through hole 211, and the area on the surface of the front shell 210 covered by the above orthographic projection is provided with an adhesive layer 300, which is used to connect the cover plate 110 and the front shell 210 respectively.

[0059] In combination with the above content, the reason why a structure for supporting the front shell frame 212 (hereinafter referred to as the internal support structure) is not provided on the front shell 210 and the rear shell 220 is, on the one hand, due to factors such as molding accuracy, it is very likely that the protruding length of the internal support structure is relatively short, so that the free end of the internal support structure cannot abut against the structural part on the opposite side (for example, the end of the internal support structure provided on the front shell 210 cannot abut against the rear shell 220), thereby causing the internal support structure to fail to play a good supporting role, or, the protruding length of the internal support structure is relatively long, so that after the front shell 210 and the rear shell 220 are connected, the front shell frame 212 bends outward under the action of the internal support structure, affecting the appearance; on the other hand, since the structures of the front shell 210 and the rear shell 220 themselves are relatively complex, if an internal support structure is provided on the front shell 210 and the rear shell 220, the preparation cost of the front shell 210 and the rear shell 220 will be further increased, which is not conducive to mass production.

[0060] Therefore, in this embodiment, the support structure 400 is connected to the back panel 120 of the display module 100. Without changing the structure of the front shell 210 and the structure of the rear shell 220, the back panel 120 can provide supporting force to the front shell frame 212 through the support structure 400. The supporting force can support the front shell frame 212 at least along the thickness direction of the front shell 210, that is, the supporting force can resist the pressure of the external force F on the front shell frame 212.

[0061] The display device provided in this embodiment is provided with a support structure 400 connected to the back panel 120 of the display module 100 and the front housing frame 212 of the front housing 210, respectively. The back panel 120 can provide support for the front housing frame 212 through the support structure 400. When the front housing frame 212 is pressed by an external force, the above support force can support the front housing frame 212 at least along the thickness direction of the front housing 210, thereby preventing the front housing frame 212 from bending or deforming under the action of the external force.

[0062] At the same time, the cover plate 110 of the display module 100 can also cover the support structure 400 to prevent the support structure 400 from causing adverse effects on the appearance of the display device.

[0063] like Figure 7 and Figure 8In some embodiments, the back panel 120 includes a bottom panel 121, and a side panel 122 connected to the bottom panel 121 and arranged along the circumferential edge of the bottom panel 121; the bottom panel 121 and the cover panel 110 are spaced apart, and the side panel 122 is located between the bottom panel 121 and the cover panel 110; the support structure 400 includes a support frame 410, which is connected to the side of the bottom panel 121 away from the cover panel 110; the support frame 410 includes a support claw 411, which abuts against the surface of the side of the front shell frame 212 away from the cover panel 110.

[0064] Exemplarily, the support frame 410 further includes a frame body 413, through which the support frame 410 is connected to the bottom plate 121. The support claw 411 is connected to the frame body 413 and extends from the frame body 413 toward the front shell frame 212 until the support claw 411 abuts against the surface of the front shell frame 212.

[0065] For example, Figure 7 , along the extension direction of the front shell frame 212 (such as Figure 7 In the X direction in the middle of the front shell frame 212, the support claw 411 abuts against the middle of the front shell frame 212. Due to the long extension length of the front shell frame 212, the middle of the front shell frame 212 has the weakest compressive strength, that is, it is most susceptible to bending and deformation due to external pressure. Therefore, the support claw 411 can be abutted against the middle of the front shell frame 212 to support the position of the front shell frame 212 that is most susceptible to bending and deformation, thereby effectively reducing the risk of bending and deformation of the front shell frame 212.

[0066] When an external force presses on the front shell frame 212, the force that causes the front shell frame 212 to bend toward the rear shell 220 is the force acting along the thickness direction of the front shell 210 toward the rear shell 220. When the supporting claws 411 abut against the side surface of the front shell frame 212 away from the cover plate 110, the force exerted by the supporting claws 411 on the front shell frame 212 is along the thickness direction of the front shell 210 toward the cover plate 110, which can more effectively resist the external force and prevent the front shell frame 212 from bending and deforming, which may lead to problems such as loosening and debonding of the front shell frame 212.

[0067] At the same time, since the support frame 410 is in contact with the front shell frame 212, there is no need to modify the structure of the front shell 210, the process feasibility is high, and the installation cost is low.

[0068] like Figure 7 and Figure 8 In some embodiments, the support frame 410 is a sheet metal structure. The support frame 410 is provided with a folded edge near the front shell frame 212 , and the folded edge is bent toward the front shell frame 212 to form a support claw 411 .

[0069] like Figure 8Along the thickness direction of the front shell 210 , since the gap between the back plate 120 and the rear shell 220 is small, the support frame 410 is selected to be a sheet metal structure with a thin thickness and a strength at least higher than that of the front shell 210 .

[0070] At the same time, since the surface of the bottom plate 121 is relatively flat, the structure of the support frame 410 can also be designed to be relatively simple. When the support frame 410 is made of sheet metal, a portion of the sheet metal can be directly used as the frame body 413 of the support frame 410, and the area of the sheet metal close to the front shell frame 212 can be bent so that the sheet metal edge of this area is bent toward the front shell frame 212 to form a support claw 411, and the side wall of the sheet metal (the side wall is parallel to the thickness direction of the sheet metal) can serve as the end of the support claw 411 and abut against the surface of the front shell frame 212. In summary, when the support frame 410 is a sheet metal structural member, not only is the material cost low, but the processing is also relatively simple, which helps to reduce the preparation cost of the support frame 410 and is conducive to mass production.

[0071] like Figure 8 In some embodiments, a claw fold 414 is provided at the end of the support claw 411 close to the front shell frame 212 , and the plate surface of the claw fold 414 abuts against the front shell frame 212 .

[0072] In order to enable the support claw 411 to better support the front shell frame 212, the contact area between the support claw 411 and the front shell frame 212 can be increased. Since the thickness of the sheet metal is relatively thin, if the side wall of the sheet metal is abutted against the surface of the front shell frame 212, the contact area between the support claw 411 and the front shell frame 212 will be smaller. In order to improve this problem, the support claw 411 can be bent on one side near the front shell frame 212 to form a claw fold 414. Since the claw fold 414 is the plate surface of the sheet metal facing the front shell frame 212, it is larger than the side wall area of the sheet metal. Therefore, when the plate surface of the claw fold 414 abuts against the front shell frame 212, the support claw 411 and the front shell frame 212 can have a larger contact area.

[0073] In some embodiments, the thickness of the support frame 410 is 0.5 mm to 2 mm.

[0074] For example, the thickness of the support frame 410 may be 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0075] Since sheet metal is a metal part, even if it is relatively thin, it can still have greater strength than plastic parts. At the same time, precisely because of the above-mentioned characteristics of sheet metal parts, when the sheet metal part is used as support frame 410, the thin support frame 410 can be well adapted to the relatively narrow space inside the housing 200 without changing the original product shape of the housing 200, thus having strong versatility.

[0076] like Figure 7 、 Figure 9a and Figure 9b In some embodiments, along the extension direction of the front shell frame 212 (such as Figure 7 In the X direction), at least two supporting claws 411 are arranged at intervals.

[0077] At least two supporting claws 411 can support different positions of the front shell frame 212, which can better prevent the front shell frame 212 from bending and deforming, thereby causing problems such as loosening and debonding of the front shell frame 212.

[0078] like Figure 7 、 Figure 8 、 Figure 9a and Figure 9b In some embodiments, at least two positioning protrusions 123 are provided on a side of the bottom plate 121 away from the cover plate 110 , and positioning holes 412 corresponding to the positioning protrusions 123 are provided on a side of the support frame 410 close to the bottom plate 121 .

[0079] Illustratively, the positioning protrusion 123 may be integrally formed and connected to the bottom plate 121 .

[0080] Illustratively, the positioning hole 412 may be a through hole (ie, passing through the support frame 410 ) or a blind hole (ie, not passing through the support frame 410 ).

[0081] Exemplarily, the positioning hole 412 may be provided on the frame body 413 of the support frame 410 .

[0082] When assembling the support frame 410 (at this time the display module 100 has been connected to the front shell 210), the positioning holes 412 of the support frame 410 can be matched with the positioning protrusions 123 on the bottom plate 121. When all the positioning protrusions 123 are respectively inserted into the corresponding positioning holes 412, the pre-positioning of the support frame 410 and the back plate 120 can be completed, and then the support frame 410 and the back plate 120 can be connected.

[0083] The pre-positioning of the support frame 410 and the back plate 120 can ensure that the support claw 411 can abut against the preset position of the front shell frame 212, which helps the support claw 411 to effectively support the front shell frame 212.

[0084] like Figure 9a and Figure 9b In some embodiments, the positioning hole 412 is arranged along the extension direction of the front shell frame 212 (eg Figure 9a There are two positioning holes 412 spaced apart in the X direction, wherein the cross-sectional shape of one positioning hole 412 matches the cross-sectional shape of the corresponding positioning protrusion 123, and the other positioning hole 412 is an oblong hole, the major axis of the oblong hole is parallel to the extension direction of the front shell frame 212.

[0085] by Figure 9a The structure and direction in the figure are used as an example to illustrate. The cross-sectional shape of the positioning protrusion 123 on the left is circular, and the cross-sectional shape of the corresponding positioning hole 412 is also circular and the diameter matches. The positioning protrusion 123 on the right is the same as the positioning protrusion 123 on the left, and the positioning hole 412 on the right is an oblong hole. The longitudinal minor axis of the oblong hole matches the diameter of the positioning protrusion 123, and the transverse major axis of the oblong hole is larger than the diameter of the positioning protrusion 123. When the oblong positioning hole 412 and the positioning protrusion 123 cooperate, the longitudinal position of the support frame 410 can be limited. When the circular positioning hole 412 and the positioning protrusion 123 cooperate, the transverse and longitudinal positions of the support frame 410 can be limited. The reason why one of the positioning holes 412 is designed as an oblong hole is to reduce the precision requirements for the spacing size between the two positioning protrusions 123, which helps to reduce processing difficulty and preparation costs.

[0086] like Figure 9b In some embodiments, the support frame 410 is connected to the base plate 121 via fasteners 500 .

[0087] Exemplarily, the fastener 500 is a screw, a rivet or a pin; when the fastener 500 is a screw, it passes through the support frame 410 and is threadedly connected to the base plate 121; when the fastener 500 is a rivet, it passes through the support frame 410 and is riveted to the base plate 121; when the fastener 500 is a pin, it passes through the support frame 410 and is interference-connected to the base plate 121.

[0088] Connecting the support frame 410 to the base plate 121 through the fasteners 500 helps to reduce the difficulty of preparation, assembly difficulty and preparation cost.

[0089] like Figure 8 In some embodiments, a protruding mounting protrusion 124 is provided on a side of the bottom plate 121 away from the cover plate 110 , and the mounting protrusion 124 is provided with a mounting hole 125 matching the fastener 500 .

[0090] Exemplarily, the support frame 410 is provided with a groove matching the mounting protrusion 124 (when the support frame 410 is a sheet metal part, the groove can be formed by bending) to ensure that the positioning protrusion 123 on the base plate 121 can cooperate with the positioning hole 412 of the support frame 410.

[0091] Exemplarily, the mounting hole 125 is a threaded hole or a through hole with a smooth wall.

[0092] Since the fastener 500 is connected to the base plate 121, it is necessary to provide a matching mounting hole 125 on the base plate 121. However, if the base plate 121 is relatively thin, the fastener 500 is likely to pass through the mounting hole 125 and enter the interior of the display module 100, thereby adversely affecting the internal structural layers of the display module 100. To avoid this problem, this embodiment provides a mounting protrusion 124 on the base plate 121 to increase the thickness of the base plate 121. This ensures that when the fastener 500 engages with the mounting hole 125, it can both securely secure the support frame 410 and the base plate 121 and prevent the fastener 500 from entering the interior of the display module 100.

[0093] In some embodiments, the support frame 410 is adhesively connected to the bottom plate 121 .

[0094] When the gap between the base plate 121 and the rear shell 220 is not sufficient to accommodate the exposed portion of the fastener 500 (such as the nut of a screw), the support frame 410 and the base plate 121 can also be connected by a strong adhesive (such as double-sided tape) so that the support frame 410 can be installed in a space with a relatively small internal space, further improving the versatility of the support frame 410.

[0095] like Figure 10 In some embodiments, at least a portion of the side panel 122 is located in the mounting through hole 211 , and the support structure 400 includes an adhesive layer 420 , which is disposed between the front shell frame 212 and the side panel 122 .

[0096] For example, the adhesive layer 420 may be a room temperature vulcanized rubber layer (RTV layer).

[0097] An adhesive layer 420 is evenly coated over a large area on the outer surface of the side panel 122 close to the front shell frame 212. The adhesive layer 420 generates a force on the front shell frame 212 by relying on its own viscosity. The force can pull and support the front shell frame 212 at least along the thickness direction of the front shell 210. When the front shell frame 212 is pressed by an external force, the force can resist the external force to reduce the risk of bending and deformation of the front shell frame 212, which helps to avoid debonding of the front shell frame 212 and the cover plate 110.

[0098] At the same time, the cost of the adhesive layer 420 is low, and setting the adhesive layer 420 does not require structural changes to the front shell 210, the back panel 120 and the rear shell 220. Therefore, it has strong versatility, especially for the situation where the structures of the front shell 210, the back panel 120 and the rear shell 220 have been fixed or have been completed, which is conducive to mass production.
