Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted display screens, in particular to a double-screen structure. Background Art

[0002] When setting up a dual-screen structure for an entertainment system in a car, before the dual-screen structure is attached, the plastic front frame used to fix the screen assembly is generally assembled into one piece with a sheet metal bracket. Since the plastic front frame with a complete structural surface design has poor flatness and a certain structural strength, it is difficult for the sheet metal bracket to correct local deformation of the plastic front frame to ensure that the plastic front frame has a higher flatness, resulting in light leakage.

[0003] Moreover, the sheet metal bracket is only fixed to the plastic front frame with screws on the lower side, and the upper side of the sheet metal bracket is not fixed to the plastic front frame with any support, which does not provide an ideal correction effect on the plastic front frame. In addition, the sheet metal bracket adopts a stamping molding process without post-processing, and there is a stress release phenomenon after long-term static storage.

[0004] In addition to the clip-on fixation, the plastic front frame and the rear shell in the dual-screen structure are also fixed with screws, making the plastic front frame susceptible to backward pulling force. Summary of the invention

[0028] See again Figure 2 and Figure 3 The dual-screen structure provided by the embodiment of the utility model includes a plastic rear shell 100, a PCB assembly 200, a die-casting bracket 300, a plastic front frame 400 and a dual-screen assembly 500; the die-casting bracket 300 is fixedly connected to the plastic rear shell 100; the PCB assembly 200 is arranged between the plastic rear shell 100 and the die-casting bracket 300, and is fixedly connected to the first end surface of the die-casting bracket 300; the plastic front frame 400 is provided with a hollow structure 410, and the plastic front frame 400 is fixedly connected to the second end surface of the die-casting bracket 300; the dual-screen assembly 500 is snapped onto the plastic front frame 400, and the dual-screen assembly 500 is adapted to the hollow structure 410.

[0029] In this embodiment, the difference from the existing dual-screen structure in which the plastic front frame adopts a complete structural surface design is that the plastic front frame 400 is provided with a hollow structure 410, and the plastic front frame 400 is fixedly connected to the second end face of the die-cast bracket 300. The hollow structure 410 reduces the overall strength of the plastic front frame 400, but before the screen is attached, the plastic front frame 400 and the die-cast bracket 300 are assembled into one body, and the die-cast bracket 300 is specifically used to ensure the flatness of the plastic front frame 400. Even after the dual-screen structure is installed and left to stand for a period of time, because the die-cast bracket 300 adopts a die-casting molding process, the die-cast bracket 300 does not need to release stress, and will not cause light leakage in the overall structure.

[0030] In one embodiment, if Figure 3 As shown, the hollow structure 410 on the plastic front frame 400 includes a first hollow groove 411 and a second hollow groove 412 , and the second hollow groove 412 is located at one side of the first hollow groove 411 .

[0031] In this embodiment, in order to adapt and install the dual screen assembly 500 on the plastic front frame 400, it can be specifically configured that the hollow structure 410 includes a first hollow groove 411 and a second hollow groove 412, and the first hollow groove 411 and the second hollow groove 412 are arranged at intervals (that is, the second hollow groove 412 is located on one side of the first hollow groove 411, and there is a certain distance between the two). Through this configuration, the dual screen assembly can be firmly connected to the plastic front frame, and the above two hollow grooves can serve as a storage space and fixing structure for the two screens in the dual screen assembly.

[0032] When implementing it, Figure 1 and Figure 3 As shown, the dual screen assembly 500 includes a first screen assembly 510 and a second screen assembly 520; when the dual screen assembly 500 is snapped onto the plastic front frame 400, the first screen assembly 510 is located in the first hollow groove 411, and the second screen assembly 520 is located in the second hollow groove 412. By providing two hollow grooves on the plastic front frame, the dual screen assembly can be more adapted to achieve fixed installation of the dual screen assembly. The PCB assembly 200 includes a first PCB assembly 210 and a second PCB assembly 220; when the PCB assembly 200 is snapped onto the plastic front frame 400, the first PCB assembly 210 is connected to the first screen assembly 510, and the second PCB assembly 220 is connected to the second screen assembly 520.

[0033] In one embodiment, if Figure 3 As shown, the plastic front frame 400 is fixedly connected to the second end surface of the die-cast bracket 300 through a plurality of connecting pieces.

[0034] In this embodiment, the connecting member can be a screw, and the plastic front frame 400 is screwed to the second end surface of the die-cast bracket 300 by a plurality of screws. The die-cast bracket 300 is extended and extended as a whole, completely covering the bonding area between the supporting plastic front frame 400 and the dual-screen assembly 500, making the overall structure more compact and less prone to light leakage.

[0035] In one embodiment, if Figure 2 As shown, a plurality of front frame buckles 420 are disposed on the end surface of the plastic front frame 400 facing the die-cast bracket 300 , so as to buckle the plastic front frame 400 to the plastic rear shell 100 .

[0036] In this embodiment, during specific implementation, a plurality of front frame buckles 420 may be provided on the first end face of the plastic front frame 400, and a plurality of rear shell male buckles may be provided on the end face of the plastic rear shell 100 facing the die-casting bracket 300; wherein, the first end face of the plastic front frame 400 is the end face thereof facing the die-casting bracket 300, and the second end face of the plastic front frame 400 is the end face thereof facing away from the die-casting bracket 300. When the plastic front frame 400 is fixedly connected to the second end face of the die-casting bracket 300, some avoidance grooves may be adaptively provided on the die-casting bracket 300 so that the plurality of front frame buckles 420 pass through the die-casting bracket 300, and then are snapped with the plurality of rear shell male buckles on the plastic rear shell 100. It can be seen that the plastic front frame is not only fixedly connected to the second end face of the die-casting bracket through a plurality of connectors, but also snapped to the plastic rear shell through the front frame buckles, thereby realizing a stable fixation of the plastic front frame.

[0037] In one embodiment, if Figure 3 , Figure 4 as well as Figure 5 As shown, the die-cast bracket 300 includes a bracket body 310, a plurality of positioning columns 320 and a plurality of raised bases 330; wherein the plurality of positioning columns 320 are arranged on the second end face of the bracket body 310, and the plurality of raised bases 330 are arranged on the first end face of the bracket body 310; the first end face of the bracket body 310 is the end face of the bracket body 310 facing the PCB assembly 200, and the second end face of the bracket body 310 is the end face of the bracket body 310 facing the plastic front frame 400.

[0038] In this embodiment, the first end face of the bracket body 310 can be regarded as the first end face of the die-cast bracket 300, and the second end face of the bracket body 310 can be regarded as the second end face of the die-cast bracket 300. When the plastic front frame 400 is fixedly connected to the second end face of the die-cast bracket 300, the plurality of positioning posts 320 provided on the second end face of the bracket body 310 support the plastic front frame 400 through the plurality of positioning posts 320 to prevent the plastic front frame 400 from deforming toward the second end face of the die-cast bracket 300 when it is connected to the die-cast bracket and the plastic rear shell. Moreover, the provided raised base can also serve as a connector mounting seat between the plastic rear shell.

[0039] In one embodiment, if Figure 4 As shown, the plurality of positioning posts 320 are disposed around the outer edge of the second end surface of the bracket body 310 .

[0040] In the present embodiment, a plurality of positioning posts 320 are disposed around the outer edge of the second end surface of the bracket body 310 because the plurality of positioning posts 320 do not need to be aligned with the first hollow groove 411 and the second hollow groove 412 on the plastic front frame 400, but are aligned with the non-hollow area on the plastic front frame 400 to support the plastic front frame 400, thereby preventing the plastic front frame 400 from being deformed toward one side of the second end surface of the die-cast bracket 300 when it is connected to the die-cast bracket and the plastic rear shell.

[0041] Moreover, when specifically setting a plurality of positioning posts 320, the distribution positions of a plurality of front frame buckles 420 set on the end surface of the plastic front frame 400 facing the die-cast bracket can also be referred to, so that a plurality of positioning posts 320 are distributed around or near a plurality of front frame buckles 420. In this way, the supporting force of a plurality of positioning posts 320 on the non-hollow area on the plastic front frame 400 offsets most of the pulling force generated by the plurality of front frame buckles 420 being connected to other structures (such as a plurality of rear shell male buckles on the plastic rear shell 100) to maintain the flatness of the plastic front frame.

[0042] In one embodiment, if Figure 4 as well as Figure 5 As shown, the plurality of raised bases 330 include a first raised base 331, a second raised base 332, a third raised base 333, a fourth raised base 334 and a fifth raised base 335; the distances between the first raised base 331, the second raised base 332 and the third raised base 333 and the bottom end of the bracket body 310 belong to a first preset distance interval; the distances between the fourth raised base 334 and the fifth raised base 335 and the bottom end of the bracket body belong to a second preset distance interval.

[0043] In this embodiment, the spacing between the first raised base 331, the second raised base 332 and the third raised base 333 and the bottom end of the bracket body 310 belongs to the first preset distance interval, indicating that the first raised base 331, the second raised base 332 and the third raised base 333 are basically located at the same height, but not necessarily completely aligned. Similarly, the spacing between the fourth raised base 334 and the fifth raised base 335 and the bottom end of the bracket body belongs to the second preset distance interval, indicating that the fourth raised base 334 and the fifth raised base 335 are basically located at the same height, but not necessarily completely aligned. By setting the above five raised bases, it can be installed on the car as a mounting structure for the entire dual-screen structure through the plastic rear shell, and can also be used as a connector mounting seat between the plastic rear shell.

[0044] In one embodiment, if Figure 3 As shown, the first protruding base 331 is provided with a first connecting member through hole 3311 , and the third protruding base 333 is provided with a second connecting member through hole 3331 .

[0045] In this embodiment, connecting member through holes can be selectively provided on some of the raised bases. Specifically, a first connecting member through hole 3311 is provided on the first raised base 331, and a second connecting member through hole 3331 is provided on the third raised base 333. By providing at least the above two connecting member through holes, the connecting member can enter the connecting member through hole again after passing through the plastic back shell, thereby realizing a fixed connection between the die-cast bracket and the plastic back shell.

[0046] In one embodiment, if Figure 3 As shown, the plastic back shell 100 includes a back shell body 110, and the back shell body 110 is provided with a first mounting groove 111, a second mounting groove 112, a third mounting groove 113, a fourth mounting groove 114 and a fifth mounting groove 115; wherein, the first mounting groove 111 is aligned with the first protruding base 331, the second mounting groove 112 is aligned with the second protruding base 332, the third mounting groove 113 is aligned with the third protruding base 333, the fourth mounting groove 114 is aligned with the fourth protruding base 334, and the fifth mounting groove 115 is aligned with the fifth protruding base 335.

[0047] In this embodiment, in order to adapt to the five raised bases on the die-cast bracket 300, five corresponding mounting grooves can be set on the rear shell body 110, and each mounting groove is aligned with a raised base. When each raised base passes through the corresponding mounting groove, the entire dual-screen structure is installed on the car as a mounting structure.

[0048] In one embodiment, if Figure 3 As shown, the plastic back shell 100 is also provided with a first connecting member mounting through hole 121 and a second connecting member mounting through hole 122; wherein, the first connecting member mounting through hole 121 is located below the first mounting groove 111 and is opposite to the first connecting member through hole 3311; the second connecting member mounting through hole 122 is located below the third mounting groove 113 and is opposite to the second connecting member through hole 3331.

[0049] In this embodiment, when the first connecting member mounting through hole 121 and the second connecting member mounting through hole 122 are also provided on the plastic rear shell 100, a first connecting member such as a first screw passes through the first connecting member mounting through hole 121 and enters the first connecting member through hole 3311, and a second connecting member such as a second screw passes through the second connecting member mounting through hole 122 and enters the second connecting member through hole 3331, thereby screwing and fixing the die-cast bracket 300 to the plastic rear shell 100, transferring the force to the die-cast bracket, and preventing the plastic front frame from being subjected to more force.
