Description

Technical Field

[0001] The utility model relates to the field of automobile intelligent cockpits, and in particular to a vehicle-mounted rear-seat entertainment ceiling screen. Background Art

[0002] With the rise of the new energy industry, people's requirements for car riding comfort are getting higher and higher. The entertainment display screen in the second row of the car can provide a comfortable riding environment for the second row passengers. The display screen can be folded and attached to the roof when not in use, and then flipped open when in use. In the existing technology, in order to improve the support strength of the display screen when folded and prevent the motor from bearing excessive load, a hole is usually opened on the side of the display screen housing. After folding, a lock tongue is inserted into the hole to support the display screen. This method has high strength requirements for the hole, and the lock tongue acts directly on the hole. Long-term use of this method can easily cause the hole to deform and affect the shape of the housing, causing the lock tongue to shift or the screen to fall off. Utility Model Content

[0003] In view of this, the utility model provides a high-strength vehicle-mounted rear-seat entertainment ceiling screen.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A vehicle-mounted rear entertainment ceiling screen includes a rear cover, a middle frame fixed within the rear cover, and a display screen fixed to the middle frame. The middle frame is a rectangular frame structure. Locking blocks are provided at the middle positions of opposite sides of the middle frame. The locking blocks are provided with locking tongue sleeves. Mounting holes are provided on the rear cover at positions opposite to the locking blocks. The locking tongue sleeves are fixed to the locking blocks after passing through the mounting holes. The locking tongue sleeves are provided with insertion holes, and the insertion holes are exposed outside the rear cover.

[0006] In the above technical solution, after the ceiling screen is folded under the drive of the motor, the external lock tongue can be inserted into the insertion hole of the lock tongue cover, so that the motor and the lock tongue can jointly support the ceiling screen, thereby enhancing the overall stability of the ceiling screen. The lock tongue cover passes through the mounting hole on the outer shell and is fixed to the lock block located on the middle frame. This design allows the lock tongue cover to be used as a detachable and replaceable component. As the active component of the lock tongue, the lock tongue cover can not only reduce the force applied to the mounting hole on the back cover, effectively preventing deformation of the mounting hole, but also serve as a fixing structure between the middle frame and the back cover, so that the middle frame can be stably fixed in the back cover to prevent shaking or falling off, thereby further improving the overall structural strength of the entertainment screen.

[0007] In addition, the locking blocks are set in the middle position of the opposite sides of the middle frame instead of the edge position, so that the locking blocks have a larger support area, and the edges of the middle frame do not need to use a thicker structure to support the locking blocks. This not only reduces the thickness of the middle frame, making the ceiling screen lighter as a whole, but also makes the edges of the middle frame thinner, thereby effectively reducing the border of the display screen, increasing the screen size, and giving the display screen a better viewing experience.

[0008] Optionally, in a possible implementation, the locking block is provided with a mounting cavity having an opening, and the lock tongue sleeve is inserted into the mounting cavity through the opening.

[0009] In the above technical solution, by providing a mounting cavity with an opening on the lock block, the lock bolt cover can be easily inserted or removed from the opening, thereby providing a certain positioning effect, allowing the lock bolt cover to be accurately installed on the lock block. In addition, because the lock bolt cover is easy to replace, when the lock bolt cover needs to be replaced due to wear or damage, only the lock bolt cover needs to be replaced, which greatly saves replacement costs.

[0010] Optionally, in a possible implementation, the lock tongue sleeve is fixed in the installation cavity by interference fit, or is fixed in the installation cavity by bolts.

[0011] In the above technical solution, the bolt cover is fixed in the mounting cavity through an interference fit, leveraging the tight compression between the materials to achieve extremely high stability and durability. This gap-free connection effectively resists vibration and impact during long-term use, reducing wear and extending the life of the lock. Furthermore, if bolts are used for fixing, the physical fastening ensures the bolt cover's secure position in the mounting cavity, maintaining its position even under high-intensity use and preventing it from loosening or falling off.

[0012] Optionally, in a possible implementation, a lock hole and a through hole are respectively provided on the inner top and bottom of the mounting cavity, the lock hole and the through hole are arranged relative to each other, the lock tongue sleeve has an upper limit hole, the limit hole is located between the lock hole and the through hole, and the bolt passes through the through hole, the limit hole and the lock hole in sequence.

[0013] In the above technical solution, the layout of the through-hole, stopper hole, and lock hole ensures that the bolt can be accurately positioned and securely fixed to the bolt cover when it passes through the through-hole, stopper hole, and lock hole. The design of the stopper hole not only restricts the vertical movement of the bolt cover, but also effectively prevents the bolt cover from shifting horizontally through the tightening action of the bolt, ensuring a stable connection between the bolt cover and the mounting cavity.

[0014] Optionally, in a possible implementation, a limiting protrusion is provided on the lock tongue sleeve, the limiting protrusion is located at the outer edge of the insertion hole, and the limiting protrusion abuts against the locking block.

[0015] In the above technical solution, the design of the limiting ridge forms a physical barrier, effectively preventing the lock bolt cover from accidentally falling off during installation or use. At the same time, it can also make it easier to position the lock bolt cover during installation, reducing installation errors.

[0016] Optionally, in a possible implementation, a plurality of positioning components are provided on a side of the middle frame facing the back cover, a card plate matching the plurality of positioning components is provided on the back cover, and the positioning components are provided on the card plate.

[0017] In the above technical solution, the positioning component is combined with the matching card plate set on the back cover to form an efficient and precise positioning mechanism, which ensures that the middle frame and the back cover can be positioned quickly and accurately during assembly, greatly reducing the assembly difficulty and error, and improving production efficiency and assembly quality.

[0018] Optionally, in a possible implementation, the positioning assembly includes two elastic clamping blocks arranged opposite to each other, and the clamping plate is clamped between the two elastic clamping blocks.

[0019] In the above technical solution, the clamping plate simply snaps between the two elastic clamping blocks, simplifying the assembly process and reducing the need for skilled operators. Furthermore, the natural elasticity of the elastic clamping blocks ensures a secure connection between the clamping plate and the positioning assembly. Furthermore, the elastic clamping blocks not only provide a secure connection but also effectively absorb and reduce vibration and noise generated by the lock's operation.

[0020] Optionally, in a possible implementation, a first reinforcing rib is provided on the middle frame, and a second reinforcing rib is provided inside the back cover.

[0021] In the above technical solution, the middle frame and the back cover are both thin structures. Therefore, the design of the first reinforcing ribs and the second reinforcing ribs can effectively increase the structural strength of the middle frame and the back cover, optimize the stress distribution of the entertainment screen, and improve the overall compression, torsion and impact resistance of the entertainment screen.

[0022] Optionally, in a possible implementation, a circuit board electrically connected to the display screen is installed on a side of the middle frame facing the back cover, and a threading hole is further provided on the middle frame.

[0023] In the above technical solution, the circuit board is directly installed on the middle frame and connected to the display screen through the wire holes. This design not only facilitates the installation of the circuit board, but also helps to optimize the electromagnetic environment inside the entertainment screen. Through reasonable line layout and shielding measures, electromagnetic interference and noise can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 6 This embodiment provides a vehicle-mounted rear-seat entertainment ceiling screen, comprising a rear cover 1, a middle frame 2 fixed within the rear cover 1, and a display screen 3 fixed to the middle frame 2. The middle frame 2 is a rectangular frame structure. Locking blocks 4 are provided at the center of opposite sides of the middle frame 2. The locking blocks 4 are provided with locking tongue sleeves 5. Mounting holes 11 are provided on the rear cover 1 at positions opposite to the locking blocks 4. The locking tongue sleeves 5 pass through the mounting holes 11 and are fixed to the locking blocks 4. The locking tongue sleeves 5 are provided with insertion holes 51, which are exposed on the exterior of the rear cover 1. Specifically, the rear cover 1 has a structure with a rectangular hole at the top. The middle frame 2 is fixed to the inner side of the rear cover 1. The display screen 3 is a rectangular plate structure that matches the rectangular hole at the top of the rear cover 1. The display screen 3 can be fixed to the middle frame 2 by bonding and is used to close the rectangular hole at the top of the rear cover 1. In addition, two locking blocks 4 are located on the two width sides of the middle frame 2, respectively.

[0035] After the ceiling screen of this embodiment is folded under the drive of the motor, the external lock tongue can be inserted into the insertion hole 51 of the lock tongue cover 5, so that the motor and the lock tongue can jointly support the ceiling screen, thereby enhancing the overall stability of the ceiling screen. The lock tongue cover 5 passes through the mounting hole 11 on the outer shell and is fixed to the lock block 4 located on the middle frame 2. This design allows the lock tongue cover 5 to be used as a detachable and replaceable component. The lock tongue cover 5, as the active component of the lock tongue, can not only reduce the force applied to the mounting hole 11 on the back cover 1, effectively preventing the mounting hole 11 from deforming, but also serve as a fixing structure between the middle frame 2 and the back cover 1, so that the middle frame 2 can be stably fixed in the back cover 1 to prevent shaking or falling off, thereby further improving the overall structural strength of the entertainment screen.

[0036] In addition, the locking blocks 4 are arranged in the middle position of the opposite sides of the middle frame 2 rather than at the edge position, so that the locking blocks 4 have a larger supporting area, and the edges of the middle frame 2 do not need to use a thicker structure to support the locking blocks 4, which not only reduces the thickness of the middle frame 2, making the ceiling screen lighter as a whole, but also makes the edges of the middle frame 2 thinner, thereby effectively reducing the border of the display screen 3, increasing the screen size, and providing the display screen 3 with a better viewing experience.

[0037] Please refer to Figure 3 and Figure 4In this embodiment, the lock block 4 is provided with an opening in the mounting cavity 41, and the bolt sleeve 5 is inserted into the mounting cavity 41 through the opening. By providing the mounting cavity 41 with an opening in the lock block 4, the bolt sleeve 5 can be easily inserted or removed from the opening, thereby providing a certain positioning effect, allowing the bolt sleeve 5 to be accurately installed on the lock block 4. Furthermore, because the bolt sleeve 5 is easy to replace, when the bolt sleeve 5 needs to be replaced due to wear or damage, only the bolt sleeve 5 needs to be replaced, significantly saving replacement costs.

[0038] In this embodiment, the bolt cover 5 is fixed in the mounting cavity 41 by an interference fit or by bolts. Specifically, the bolt cover 5 can be made of plastic and can be elastically engaged in the mounting cavity 41. Alternatively, the bolt cover 5 and the mounting cavity 41 can be loosely fitted and fixed by bolts.

[0039] Specifically, the bolt cover 5 is secured within the mounting cavity 41 via an interference fit, leveraging the tight compression between the materials to achieve exceptional stability and durability. This gap-free connection effectively resists vibration and impact during long-term use, reducing wear and extending the lifespan of the lock. Furthermore, bolted fastening ensures the bolt cover 5's physical securement within the mounting cavity 41, maintaining its position and preventing it from loosening or falling out, even under intense use.

[0040] When the lock tongue cover 5 is fixed in the installation cavity 41 by bolts, a lock hole 43 and a through hole 42 are respectively provided at the top and bottom of the inner side of the installation cavity 41. The lock hole 43 and the through hole 42 are arranged opposite to each other. The lock tongue cover 5 has an upper limit hole 52, and the limit hole 52 is located between the lock hole 43 and the through hole 42. The bolt passes through the through hole 42, the limit hole 52 and the lock hole 43 in sequence. Specifically, the through hole 42, the limit hole 52 and the lock hole 43 are coaxially arranged. The lock hole 43 is a threaded hole. The bolt is inserted into the limit hole 52 from the bottom of the through hole 42 until it is threadedly connected to the lock hole 43. The end of the bolt abuts against the lock tongue cover 5, that is, the lock tongue cover 5 and the locking block 4 are fixedly connected by the bolt.

[0041] The arrangement of the through hole 42, the limiting hole 52, and the locking hole 43 in this embodiment ensures that the bolt can accurately position and firmly secure the bolt cover 5 when passing through the through hole 42, the limiting hole 52, and the locking hole 43. The design of the limiting hole 52 not only limits the vertical movement of the bolt cover 5, but also effectively prevents the bolt cover 5 from shifting in the horizontal direction through the tightening action of the bolt, thereby ensuring a stable connection between the bolt cover 5 and the mounting cavity 41.

[0042] Please refer to Figure 4 and Figure 6In this embodiment, a limiting protrusion 53 is provided on the lock tongue cover 5. The limiting protrusion 53 is located at the outer edge of the insertion hole 51 and abuts against the lock block 4. Specifically, the limiting protrusion 53 extends radially outward from the opening and is located at the end of the opening. The outer edge of the limiting protrusion 53 matches the installation opening on the rear cover 1, and the limiting protrusion 53 abuts the opening of the installation cavity 41.

[0043] The design of the limiting ridge 53 forms a physical barrier, effectively preventing the bolt cover 5 from accidentally falling off during installation or use. At the same time, it can also make it easier to position the bolt cover 5 during installation, reducing installation errors.

[0044] Please refer to Figure 4 and Figure 5 In this embodiment, multiple positioning components are provided on the side of the middle frame 2 facing the back cover 1. A card plate 12 is provided on the back cover 1 to match the multiple positioning components, and the positioning components are mounted on the card plate 12. The positioning components, combined with the matching card plate 12 provided on the back cover 1, form an efficient and precise positioning mechanism, ensuring that the middle frame 2 and back cover 1 can be quickly and accurately positioned during assembly, greatly reducing assembly difficulty and errors, and improving production efficiency and assembly quality.

[0045] The positioning assembly of this embodiment includes two elastic blocks 21 arranged opposite to each other, and the card plate 12 is clamped between the two elastic blocks 21. The two elastic blocks 21 are provided with opposite arc edges to facilitate the clamping of the card plate 12 between the two elastic blocks 21.

[0046] The clamping plate 12 simply snaps between the two elastic clamping blocks 21, simplifying the assembly process and reducing the need for skilled operators. Furthermore, the natural elasticity of the elastic clamping blocks 21 ensures a secure connection between the clamping plate 12 and the positioning assembly. Furthermore, the design of the elastic clamping blocks 21 not only provides a secure connection but also effectively absorbs and reduces vibration and noise generated by the lock's operation.

[0047] Please refer to Figure 2 and Figure 3 In this embodiment, a first reinforcing rib 22 is provided on the middle frame 2, and a second reinforcing rib 13 is provided inside the back cover 1. Both the middle frame 2 and the back cover 1 are relatively thin structures. Therefore, the design of the first reinforcing rib 22 and the second reinforcing rib 13 effectively increases the structural strength of the middle frame 2 and the back cover 1, optimizes the stress distribution of the entertainment screen, and improves the overall compression, torsion, and impact resistance of the entertainment screen.

[0048] It should be noted that a circuit board 6 electrically connected to the display screen 3 is mounted on the side of the middle frame 2 facing the rear cover 1. The middle frame 2 is also provided with threading holes 23. When connecting the circuit board 6 and the display screen 3, the cables can be passed through the threading holes 23 to establish a connection between the two. The design of directly mounting the circuit board 6 on the middle frame 2 and connecting it to the display screen 3 through the threading holes 23 not only facilitates the installation of the circuit board 6, but also helps optimize the electromagnetic environment within the entertainment screen. Through reasonable circuit layout and shielding measures, electromagnetic interference and noise can be reduced.
