Description

Technical Field

[0001] This invention relates to the field of display device accessories, and in particular to a mechanism for a car roof-mounted display screen. Background Technology

[0002] The existing methods for installing roof-mounted rear seat displays in automobiles include: automobile modification and the original display configuration in the automobile.

[0003] (1) Car modification: Mostly ceiling-mounted displays, with a rotating shaft at one end and a magnetic connection to the car roof at the other. A motor controls the rotation of the display to open or close it. The stability of the display opening and closing is ensured only by the self-locking force of the motor. If there is shaking on a bumpy road, the display may fall off.

[0004] (2) Existing Car Display Screen Configuration: A rotating shaft is installed at the front of the display screen, and a pin telescopic device is installed at the rear. The pin is inserted into the rear of the display screen to close it, and pulled out to open it. The pin is controlled by an actuator. When the screen is to be opened, the actuator controls the pin to retract. After retraction, the motor starts working, and the display screen rotates and descends around the rotating shaft until it is fully open. When the screen is to be closed, the motor works, causing the display screen to rotate and rise around the rotating shaft to the fully closed position. The actuator then controls the pin to insert into the groove structure at the other end of the display screen to ensure the stability of the screen when closed. This mechanism has two internal motion control systems, making it complex and costly. Furthermore, if the display screen malfunctions, the plastic cover on the roof needs to be removed, and the entire assembly needs to be removed from the roof for replacement, resulting in high repair costs.

[0005] The current installation method of roof-mounted rear seat displays in automobiles results in slightly smaller screen sizes and lacks an independent locking mechanism. Modifications to the vehicle rely on the motor itself for opening and closing. The original display configuration in the car is locked by a motor after opening. The smoothness of opening and closing the display cannot be guaranteed, posing a risk of the display shaking or falling off the roof. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a vehicle roof-mounted display screen mechanism that is simple in structure, has a single control system, and has good stability, in order to address the above-mentioned shortcomings.

[0007] This invention is achieved through the following technical solution:

[0008] A vehicle roof-mounted display screen mechanism includes two symmetrically arranged half-side mechanisms, each half-side mechanism comprising:

[0009] A screen mounting bracket is fixedly connected to the rear of the display screen along the side of the display screen;

[0010] A sliding mechanism is hinged to one end of the screen mounting bracket and can slide along the first top guide rail; and

[0011] A fixing block is fixed to the first top guide rail and hinged to the middle of the screen fixing frame via a connecting rod;

[0012] The sliding mechanism slides along the first top guide rail from a position away from the fixed block to a position close to the fixed block, and the device gradually changes from a closed state to an open state.

[0013] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the sliding mechanism includes:

[0014] The slider is installed in the first top guide rail and is hinged to one end of the screen fixing frame;

[0015] A locking block, one end of which is hinged to the slider; when the locking block rotates about one end as an axis, causing the other end to engage in the guide rail limiting groove of the first top guide rail, the device is in a closed state; and

[0016] A drive slider is connected to a motor and the locking block; the motor drives the drive slider to move, and the drive slider drives the locking block to rotate and slide along the first top guide rail.

[0017] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the locking block is provided with a stepped locking block trajectory groove along the length direction of the first roof-mounted guide rail; the driving slider is provided with a driving slider foot that is slidably connected to the locking block trajectory groove; the driving slider foot slides along the locking block trajectory groove to rotate the locking block.

[0018] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the locking block trajectory groove includes a first-order horizontal groove, a second-order horizontal groove, and a vertical groove connecting the first-order horizontal groove and the second-order horizontal groove. The first-order horizontal groove, the second-order horizontal groove, and the vertical groove are all inclined in the direction of the stepped trend.

[0019] Furthermore, the aforementioned automotive roof-mounted display screen mechanism further includes a second roof-mounted guide rail arranged parallel to the first roof-mounted guide rail; the drive slider is mounted on the second roof-mounted guide rail.

[0020] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the fixing block is provided with an opening groove along the length direction of the first roof-mounted guide rail, and the locking block is provided with a locking block sliding foot that can enter from the opening end of the opening groove and slide therewith.

[0021] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the opening slot includes a flat slot extending inward from the opening end and parallel to the first roof-mounted guide rail, and an inclined slot extending obliquely from the flat slot; the locking block slides along the first roof-mounted guide rail toward the fixing block, and the sliding foot of the locking block enters from the opening end into the flat slot and engages with the inclined slot, and the device is in the open state.

[0022] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the other end of the locking block is provided with a limiting structure to limit the angle at which its other end engages with the guide rail limiting groove.

[0023] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, a boss extends outward from the edge of the fixing block, and a groove is provided on the edge of the screen fixing frame to cooperate with the boss; when the device is in the closed state, the boss and the groove are locked together.

[0024] Furthermore, in the aforementioned automotive roof-mounted display screen mechanism, the screen mounting bracket includes:

[0025] A side fixing member is disposed on the side of the display screen and connected to the sliding mechanism and the connecting rod; and

[0026] A connector extends from the side of the side fastener toward the rear of the display screen and is locked to the rear of the display screen by screws.

[0027] The advantages and effects of this invention are:

[0028] 1. The automotive roof-mounted display screen mechanism provided by this invention uses only a sliding mechanism to control the opening or closing state. It adopts a separate control system, has a simple, mature, and reliable structure, good stability, can accommodate large-size displays, and has high platform applicability.

[0029] 2. The opening or closing state of the automotive roof-mounted display screen mechanism provided by the present invention is mechanically locked, which can effectively prevent the display screen from shaking or falling off, and also protect the motor of the control system and extend its service life.

[0030] 3. The automotive roof-mounted display screen mechanism provided by this invention can be installed separately on the roof reinforcement beam, and then the display screen is installed. The screen fixing bracket is locked to the rear of the display screen with screws. When disassembling the display screen, there is no need to remove other accessories, only the rear screws need to be removed, which provides convenience for the replacement and maintenance of the display screen.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Figure 1This diagram illustrates the closed state of the automotive roof-mounted display screen mechanism provided by the present invention. The mechanism includes two symmetrically arranged half-side mechanisms, with the display screen 1 positioned between them. The two half-side mechanisms synchronously move the display screen 1 between closed and open states. Each half-side mechanism includes a screen mounting bracket 2, a first top-mounted guide rail 3, a sliding mechanism 4, and a fixing block 5. The screen mounting bracket 2 is fixedly connected to the rear of the display screen 1 along its side. This rear connection maximizes the use of space on both sides of the display screen. For maintenance and disassembly, the display can be removed by detaching the rear connection without disassembling the entire mechanism. The first top-mounted guide rail 3 is fixed to the roof reinforcement beam, and the sliding mechanism 4 is mounted on the first top-mounted guide rail 3. The sliding mechanism 4 is hinged to one end of the screen mounting bracket 2 (usually the upper end adjacent to the display screen) and can slide along the first top-mounted guide rail 3. The fixing block 5 is fixed to the first top-mounted guide rail 3 and hinged to the middle of the screen mounting bracket 2 via a connecting rod 6. Specifically, one end of the connecting rod 6 is hinged to the fixed block 5, and the other end is hinged to the middle of the screen mounting bracket 2. The sliding mechanism 4 slides along the first top guide rail 3 from a position away from the fixed block 5 to a position close to the fixed block 5, and the car roof display mechanism gradually changes from a closed state to an open state, while the display screen 1 changes from a closed state parallel to the car roof (e.g., ...). Figure 1 Change to the opening position at the angle required by the customer (e.g.) Figure 12 From the closed state to the open state, this automotive roof-mounted display mechanism can achieve an angle range of 0 to 130° with the vehicle roof. The specific fully open angle can be set according to the customer's actual needs. In the preferred open state, the display screen is at a 105° angle with the vehicle roof.

[0051] Specifically, such as Figure 16 As shown, the screen mounting bracket 2 includes a side fixing member 23 disposed on the side of the display screen 1 and a connecting member 22 extending from the side of the side fixing member 23 toward the rear of the display screen 1. The side fixing member 23 is connected to the sliding mechanism 4 and the connecting rod 6 respectively. That is, the end of the side fixing member 23 adjacent to the upper end of the display screen is hinged to the sliding mechanism 4, and the middle part of the side fixing member 23 is hinged to the fixing block 5 through the connecting rod 6. The connecting member 22 is locked to the rear of the display screen 1 by screws, so that the rear of the display screen 1 is fixedly connected to the screen mounting bracket 2. The screen mounting bracket 2 of the half-side mechanism device may have at least two connecting members 22 extending from the side of one side fixing member 23, and the two connecting members 22 have a certain stable distance between them.

[0052] like Figure 2 , 3As shown, the sliding mechanism 4 includes a slider 41, a locking block 42, and a driving slider 43. The slider 41 is mounted within the first top-mounted guide rail 3 and slides along it, hinged to one end of the screen mounting bracket 2 (usually the upper end adjacent to the display screen). The locking block 42 is positioned along the length of the first top-mounted guide rail 3, with one end hinged to the slider 41. When the locking block 42 rotates around one end, the other end can engage with the guide rail limiting groove 31 of the first top-mounted guide rail 3, placing the automotive roof-mounted display screen mechanism in a closed and locked state. Figure 4 As shown. The drive slider 43 is connected to the motor and the locking block 42. The motor drives the drive slider 43 to move, and the drive slider 43 drives the locking block 42 to rotate around one end of its axis, causing the other end of the locking block 42 to engage or pull out of the guide rail limiting groove 31. After the other end of the locking block 42 is pulled out of the guide rail limiting groove 31 or engaged in front of the guide rail limiting groove 31, the drive slider 43 can drive the locking block 42 to move, and the locking block 42 drives the slider 41 to slide along the first top guide rail 3. Specifically, as shown... Figure 4 , 5 As shown in Figure 6, the locking block 42 is provided with a stepped locking block track groove 44 along the length direction of the first top guide rail 3, and the driving slider 43 is provided with a driving slider foot 45 that is slidably connected to the locking block track groove 44. Figure 3 As shown, the drive slider 43 is mounted on the second top guide rail 32, which is parallel to the first top guide rail 3 and positioned on the roof reinforcing beam. Specifically, it is preferably as follows... Figure 13 As shown, the first top guide rail 3 and the second top guide rail 32 can be connected side by side and integrally formed, or it can be understood as forming two parallel grooves on one guide rail. The driving slider foot 45 slides along the locking block trajectory groove 44 to rotate the locking block 42. Specifically, the stepped locking block trajectory groove 44 includes a first-order horizontal groove, a second-order horizontal groove, and a vertical groove connecting the first-order horizontal groove and the second-order horizontal groove. The first-order horizontal groove, the second-order horizontal groove, and the vertical groove are all inclined in the direction of the stepped trend. A limiting structure 46 is provided at the other end of the locking block to limit the angle at which its other end is engaged in the guide rail limiting groove 31, so as to facilitate being pulled out. The driving slider foot 45 slides from Figure 4 Slide to the position shown Figure 5 The position shown allows the locking block 42 to rotate about one end of its axis, while the other end is pulled out from the guide rail limiting groove 31; from Figure 5 Slide to the position shown Figure 6 At the indicated position, the drive slider 43 moves the locking block 42, which in turn moves the slider 41 along the first top guide rail 3. The slider 41 then moves the upper end of the screen mounting bracket 2 along the first top guide rail 3, causing the car roof display mechanism to be positioned as shown. Figure 7 The image shows the partially open state.

[0053] like Figure 8As shown, the fixing block 5 has an opening groove 51 along the length of the first top guide rail 3, and the locking block 42 has a locking block sliding foot 47. The locking block 42 slides along the first top guide rail 3 to the position of the fixing block 5, and the locking block sliding foot 47 can enter from the opening end 52 of the opening groove 51 and slide into the opening groove 51. Specifically, the opening groove 51 includes a flat groove extending inward from the opening end 52 and parallel to the first top guide rail 3, and an inclined groove extending obliquely from the flat groove. The locking block 42 slides along the first top guide rail 3 towards the fixing block 5, as... Figure 8 As shown, the locking block sliding foot 47 enters the flat groove from the open end 52 and continues to slide until... Figure 11 As shown, the vehicle's roof-mounted display screen mechanism is engaged with the inclined slot at the indicated position, and is in the open / locked state. Figure 10 , 12 As shown.

[0054] like Figure 14 As shown, a boss 53 extends outward from the edge of the fixing block 5, and a groove 21 that mates with the boss 53 is provided on the edge of the screen fixing bracket 2. Figure 15 As shown, when the vehicle roof display mechanism is in the closed state, the boss 53 engages with the groove 21 to form a closed and locked state. That is, when the vehicle roof display mechanism is in the closed state, the boss 53 engages with the groove 21 on the lower side of the display screen, and the other end of the locking block 42 is engaged in the guide rail limiting groove 31 on the upper side of the display screen, so both the upper and lower sides of the display screen are locked and protected.

[0055] When the car roof-mounted display mechanism is in the closed state, the other end of the locking block is engaged in the guide rail limiting groove. The guide rail limiting groove restricts the X-axis (sliding direction) movement of the locking block. The cross-section of the first top-mounted guide rail provides Y-axis limiting for the locking block. The Z-axis limiting structure of the drive slider presses down on the locking block, limiting its Z-axis movement and ensuring the locking stability of the mechanism in the closed state. The drive slider moves along the locking block's trajectory groove, pulling the locking block out of the guide rail limiting groove. After the locking block is unlocked, it drives the slider to cause the display screen to begin flipping. The bottom surface of the locking block slides seamlessly with the Z-axis functional surface of the first top-mounted guide rail. Subsequently, the drive slider and the locking block connect as one unit along the first top-mounted guide rail, moving into the fixed block trajectory groove. The locking block's sliding foot moves along the fixed block trajectory groove to the X-axis locking position. Then, the drive slider moves along the locking block trajectory groove to its end, limiting the locking block in the Z-axis direction, thereby locking the car roof-mounted display mechanism in the open state and ensuring its stability. The automotive roof-mounted display mechanism occupies little space in the Y direction, and its length can be quickly adjusted to fit the opening in the vehicle's roof without any changes to the mechanism's principle. The platform also offers high scalability. When the mechanism is closed, the protrusions on the fixing block and the grooves on the screen mounting bracket limit the display's movement in the X and Z directions, preventing vibrations, noises, and the risk of detachment on winding roads.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made within the protection scope of the present invention should be considered to fall within the protection scope of the present invention.
