Description

Technical Field

[0001] This invention relates to the field of vehicle display technology, and in particular to a vehicle display that is easy to store and retract. Background Technology

[0002] Currently, with the development of the automotive industry, the level of in-vehicle information technology and people's demands for technological sophistication are also increasing. Vehicles are typically equipped with in-vehicle displays. These displays are located on the vehicle's dashboard and can be used to display information, such as navigation information, video information, or audio information.

[0003] Drivers often use in-vehicle displays for navigation when encountering unfamiliar roads. When the driver doesn't need the display, it's exposed on the outside of the dashboard, easily attracting the driver's attention and affecting driving safety. Therefore, in-vehicle displays usually need to be equipped with a folding mechanism to store them inside the dashboard. This requires designing the display as a foldable dual-screen structure, making the structure of the display and its folding mechanism complex and the folding operation inconvenient. Furthermore, in actual use, because the foldable dual-screen structure has gaps for rotation, dust can easily enter the screens through these gaps, requiring screen cleaning and maintenance. In addition, the presence of hinges in the foldable dual-screen structure prevents a unified large-screen appearance, affecting the user experience. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by designing an easy-to-fold vehicle display screen. It uses a single display panel with a folding rod to achieve flip-out storage, resulting in a simple structure and convenient folding operation. The cleaning layer enables automatic cleaning, providing both dust protection and screen protection, reducing maintenance operations. It also features an integrated large screen visual effect, improving the user experience.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a retractable vehicle-mounted display screen, comprising: An instrument mounting platform has a first snap-fit ​​groove at its lower part and a storage groove at its upper part. A cleaning layer is provided on the bottom inner wall of the storage groove, and a horizontally arranged retractable rod is slidably provided on the top inner wall of the storage groove. A second snap-fit ​​groove is provided on the bottom surface of the retractable rod. The display panel has a connecting base mounted on its upper part, which is pivotally connected to the outer end of the retractable rod. An operating structure is pivotally connected to the lower part of the display panel, a portion of which is exposed and protrudes from the side wall of the display panel away from the retractable rod. The operating structure has a latching structure, which is exposed on the side wall of the display panel near the retractable rod. When the latching structure is engaged in the first latching slot, the display panel is vertical and relatively perpendicular to the retractable rod. When the latching structure is engaged in the second latching slot, the display panel is horizontal and relatively fitted against the retractable rod. When the display panel in a horizontal position extends outward or retracts inward relative to the storage slot, a portion of the exposed operating structure protruding from the side wall of the display panel contacts the cleaning layer and generates friction. The driving torque generated by the friction force on the operating structure causes the operating structure to rotate, so that the latching structure disengages from the second latching slot to release the display panel, or the latching structure engages with the second latching slot to position the display panel.

[0006] Preferably, the outer end of the retractable rod is provided with a movable groove, a centering shaft is provided in the movable groove, and the connecting seat is provided with a centering hole for the centering shaft to be rotatably connected.

[0007] Preferably, an elastic pin is provided on the inner wall of the movable slot, and a first positioning slot and a second positioning slot are offset on the outer wall of the connecting seat, with the included angle between the first positioning slot and the second positioning slot being 90°; when the display panel is in a horizontal state and is relatively attached to the retracting rod, the ball end of the elastic pin abuts against the inner wall of the first positioning slot; when the display panel is in a vertical state and is relatively perpendicular to the retracting rod, the ball end of the elastic pin abuts against the second positioning slot.

[0008] Preferably, a guide groove is provided through the lower part of the display panel, an operating shaft is provided in the guide groove, the operating structure is a ring structure, the operating structure is sleeved on the operating shaft, and the inner wall of the guide groove includes two guide walls arranged opposite to each other, the guide walls abutting against the outer wall of the operating structure.

[0009] Preferably, when the display panel is in contact with the opposite side of the retractable rod, the guide groove corresponds to and communicates with the second snap-fit ​​groove; when the display panel is in contact with the opposite side of the instrument mounting platform, the guide groove corresponds to and communicates with the first snap-fit ​​groove. The inner wall of the guide groove includes a first limiting wall and a second limiting wall. The snap-fit ​​structure swings within the space between the first limiting wall and the second limiting wall. When the first limiting wall abuts against the snap-fit ​​structure, the snap-fit ​​structure extends to the opening side of the guide groove and is engaged in the first snap-fit ​​groove or the second snap-fit ​​groove. When the second limiting wall abuts against the snap-fit ​​structure, the snap-fit ​​structure disengages from the first snap-fit ​​groove or the second snap-fit ​​groove and does not extend to the opening side of the guide groove.

[0010] Preferably, the second limiting wall is provided with an adsorption part, both the adsorption part and the snap-fit ​​structure are made of magnetic material, and the magnetic force between the adsorption part and the snap-fit ​​structure is an attraction force; when the display panel in the horizontal state retracts inward relative to the storage groove, a part of the exposed operating structure protruding on the side wall of the display panel contacts the cleaning layer and generates friction. The driving torque formed by the friction force acting on the operating structure is greater than the resisting torque formed by the magnetic adsorption between the adsorption part and the snap-fit ​​structure, so that the operating structure can rotate relative to the guide groove and the adsorption part is disengaged from the second limiting wall.

[0011] Preferably, the top inner wall of the storage slot is provided with a sliding groove for the retractable rod to slide and connect, the length of the sliding groove is greater than the length of the storage slot, the retractable rod is provided with a positioning strip extending along its length direction, and the inner wall of the sliding groove is provided with a positioning groove for the positioning strip to slide and connect.

[0012] Preferably, it further includes a translation drive device for driving the retractable rod to translate. The translation drive device includes a drive mounting block, a rotating mechanism, and a drive gear. The rotating mechanism is disposed on the drive mounting block, and the drive gear is disposed on the rotating end of the rotating mechanism. The top surface of the instrument mounting platform has a connecting groove that communicates with the slide groove. The drive mounting block is installed in the connecting groove, so that the drive gear extends into the slide groove. The top surface of the retractable rod near the connecting groove has a rack groove extending along its length direction, and the rack groove meshes with the drive gear.

[0013] Preferably, an installation plate is installed on the bottom inner wall of the storage tank, and the installation plate has an installation groove for installing the cleaning layer.

[0014] Preferably, the instrument mounting platform is hollow inside to form a storage cavity, and a retrieval port communicating with the storage cavity is provided through the side wall of the instrument mounting platform. The retrieval port is located above the first buckle groove. When the buckle structure is engaged in the first buckle groove, the display panel abuts or gaps against the side wall of the instrument mounting platform, so that the display panel covers the retrieval port.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The user controls the display panel in a horizontal position to extend outward or retract inward relative to the storage slot, completing the operation of the vehicle display screen. During the operation, the display panel is automatically released when pulled out, pressing its display surface against the cleaning layer for automatic cleaning, thanks to the friction between the cleaning layer and the operating mechanism. When the display panel is pushed in, it is automatically locked, keeping its display surface in slight contact with the cleaning layer, thus achieving both dust prevention and screen protection. This vehicle display screen uses a single display panel with a retraction lever for flip-and-store storage, featuring a simple structure and convenient operation. The cleaning layer enables automatic cleaning, providing both dust prevention and screen protection, reducing maintenance operations, and also offers the visual effect of an integrated large screen, improving the user experience.

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0019] refer to Figures 1 to 5 A retractable vehicle display screen includes an instrument panel mounting platform 1, a display panel 2, and a translation drive device 3. The lower part of the instrument panel mounting platform 1 has a first latching groove 101, and the upper part of the instrument panel mounting platform 1 has a storage slot 102 for storing the display panel 2. A horizontally arranged retractable rod 4 is slidably mounted on the top inner wall of the storage slot 102, and a second latching groove 401 is provided on the bottom surface of the retractable rod 4. The top inner wall of the storage slot 102 has a sliding groove 103 for sliding connection of the retractable rod 4. The length of the sliding groove 103 is greater than the length of the storage slot 102. The retractable rod 4 is provided with a positioning strip 402 extending along its length. The inner wall of the sliding groove 103 has a positioning groove 104 for sliding connection of the positioning strip 402, allowing the retractable rod 4 to translate horizontally and extend outward or retract inward relative to the storage slot 102.

[0020] The translation drive device 3 is used to drive the retractable rod 4 to translate. The translation drive device 3 includes a drive mounting block 31, a rotating mechanism 32 and a drive gear 33. The rotating mechanism 32 is disposed on the drive mounting block 31, and the drive gear 33 is disposed on the rotating end of the rotating mechanism 32. The top surface of the instrument mounting platform 1 is provided with a connecting groove 105 that communicates with the slide groove 103. The drive mounting block 31 is installed in the connecting groove 105, so that the drive gear 33 extends into the slide groove 103. The top surface of the retractable rod 4 near the connecting groove 105 is provided with a rack groove 403 extending along its length direction. The rack groove 403 has a plurality of rack protrusions arranged in a linear array. The rack groove 403 meshes with the drive gear 33.

[0021] A cleaning layer 5 is provided on the bottom inner wall of the storage slot 102. The cleaning layer 5 can be made of materials such as non-woven fabric or polyurethane sponge. Preferably, an installation plate 6 is installed on the bottom inner wall of the storage slot 102. The installation plate 6 has an installation groove 601 for installing the cleaning layer 5, so that the user can remove and replace the cleaning layer 5. The installation plate 6 is slidably connected to the storage slot 102. The opposite sides of the installation plate 6 and the storage slot 102 are respectively provided with a positioning protrusion and a positioning groove (not shown in the figure). When the installation plate 6 is inserted into the storage slot 102 and is in place, the positioning protrusion is squeezed into the positioning groove to position the installation plate 6 in the storage slot 102.

[0022] A connecting seat 201 is installed on the upper part of the display panel 2. The connecting seat 201 is fixed to the back side of the display panel 2 by bolt connection, and the top surface of the connecting seat 201 mates with the top surface of the display screen. A movable groove 404 is provided on the outer end of the retractable rod 4. A centering shaft 405 is provided in the movable groove 404. A centering hole 202 is provided through the connecting seat 201 for the centering shaft 405 to rotate and connect, so that the connecting seat 201 is pivotally connected to the outer end of the retractable rod 4.

[0023] An operating structure 7 is pivotally connected to the lower part of the display panel 2. A portion of the operating structure 7 is exposed and protrudes from the side wall of the display panel 2 away from the retractable lever 4. The side wall of the display panel 2 away from the retractable lever 4 is the display side of the display panel 2. A latching structure 701 is provided on the operating structure 7, and the latching structure 701 is exposed on the side wall of the display panel 2 near the retractable lever 4. When the latching structure 701 is engaged in the first latching groove 101, the display panel 2 is in a vertical state and is relatively perpendicular to the retractable lever 4; when the latching structure 701 is engaged in the second latching groove 401, the display panel 2 is in a horizontal state and is relatively attached to the retractable lever 4.

[0024] A guide groove 21 is provided through the lower part of the display panel 2. An operating shaft 2101 is provided inside the guide groove 21. The operating structure 7 is a ring structure and is sleeved on the operating shaft 2101 to center the operating structure 7. The inner wall of the guide groove 21 includes two guide walls 211 arranged opposite to each other, and a first limiting wall 212 and a second limiting wall 213 arranged opposite to each other. The guide walls 211 abut against the outer wall of the operating structure 7 to guide the rotation of the operating structure 7. The first limiting wall 212 and the second limiting wall 213 are located on the back side of the display panel 2. When the operating structure 7 rotates, the latching structure 701 swings in the space between the first limiting wall 212 and the second limiting wall 213.

[0025] refer to Figures 1 to 12 When the display panel 2 in a horizontal state extends outward or retracts inward relative to the storage groove 102, a portion of the exposed and protruding operating structure 7 on the side wall of the display panel 2 comes into contact with the cleaning layer 5 and generates friction. The driving torque formed by the friction force on the operating structure 7 drives the operating structure 7 to rotate, so that the latching structure 701 is disengaged from the second latching groove 401 to release the display panel 2, or the latching structure 701 is engaged in the second latching groove 401 to position the display panel 2.

[0026] When using this vehicle display screen, the user only needs to control the extension lever 4 to extend outward, so that the horizontal display panel 2 extends outward relative to the storage slot 102. The side wall of the display panel 2 away from the extension lever 4 is the display surface. A part of the exposed and protruding operating structure 7 on the side wall of the display panel 2 comes into contact with the cleaning layer 5 and generates friction. The driving torque formed by the friction force on the operating structure 7 drives the operating structure 7 to rotate until the second limiting wall 213 abuts against the latching structure 701, so that the latching structure 701 disengages from the second latching slot 401, and the latching structure 701 does not extend to the opening side of the guide slot 21, so that the display panel 2 has the tendency to rotate relative to the extension lever 4 under its own weight. During the process of the display panel 2 extending outward relative to the storage slot 102, the display surface of the released display panel 2 is pressed onto the cleaning layer 5 so that the cleaning layer 5 cleans the display surface of the display panel 2.

[0027] Until the display panel 2 is completely detached from the storage slot 102, the display panel 2 rotates downward to a vertical position under its own weight. The user controls the retraction lever 4 to retract inward so that the display panel 2 is attached to the side wall of the instrument mounting platform 1. When the display panel 2 is attached to the opposite side of the instrument mounting platform 1, the guide groove 21 corresponds to and communicates with the first snap-fit ​​groove 101. Then, the user controls the operating structure 7 to rotate until the first limiting wall 212 abuts against the snap-fit ​​structure 701. The snap-fit ​​structure 701 extends to the opening side of the guide groove 21 and snaps into the first snap-fit ​​groove 101 to position the display panel 2.

[0028] When storing the vehicle display screen, the user controls the operating mechanism to rotate, causing the latching structure 701 to rotate until it abuts against the second limiting wall 213. At this time, the latching structure 701 does not extend to the opening side of the guide groove 21, and the latching structure 701 is disengaged in the first latching groove 101. The user then controls the retracting rod 4 to extend outward so that the display panel 2 can be rotated upward to a horizontal position, so that the horizontal display panel 2 is in contact with the retracting rod 4. When the opposite sides of the display panel 2 and the retracting rod 4 are in contact, the guide groove 21 corresponds to and communicates with the second latching groove 401. Afterward, the user controls the retracting rod 4 to retract inward so that the horizontal display panel 2 is in contact with the guide groove 2. As the storage slot 102 retracts inward, a portion of the exposed and protruding operating structure 7 on the side wall of the display panel 2 comes into contact with the cleaning layer 5, generating friction. The driving torque formed by the friction acting on the operating structure 7 drives the operating structure 7 to rotate until the latching structure 701 abuts against the first limiting wall 212. At this point, the latching structure 701 extends to the opening side of the guide groove 21 and latches into the second latching groove 401, thereby positioning the display panel 2. This allows the display surface of the display panel 2 to make slight contact with the cleaning layer 5, protecting the display surface of the display panel 2 and preventing a large area of ​​the display surface of the display panel 2 from being squeezed onto the cleaning layer 5.

[0029] The user controls the display panel 2 in a horizontal position to extend outward or retract inward relative to the storage slot 102, completing the retraction and unfolding operation of the vehicle display screen. During the retraction and unfolding process, with the help of the frictional cooperation between the cleaning layer 5 and the operating structure 7, the display panel 2 is automatically released when it is pulled out, so that its display surface is pressed onto the cleaning layer 5 for automatic cleaning. When the display panel 2 is pushed in, it is automatically locked so that its display surface is kept in slight contact with the cleaning layer 5, thus taking into account both dust prevention and screen protection. The vehicle display screen uses a single display panel 2 with the unfolding rod 4 to achieve flip storage. The structure is simple and the unfolding and unfolding operation is relatively convenient. Automatic cleaning is achieved through the cleaning layer 5, which takes into account both dust prevention and screen protection, reducing maintenance operations. When in use, the vehicle display screen also has the visual effect of an integrated large screen, improving the user experience.

[0030] refer to Figure 3 , Figure 4 , Figure 7 , Figure 8The second limiting wall 213 is embedded with an adsorption part 2102. Both the adsorption part 2102 and the snap-fit ​​structure 701 are made of magnetic materials. The magnetic force between the adsorption part 2102 and the snap-fit ​​structure 701 is an attraction force. When the snap-fit ​​connector is disengaged and enters the guide groove 21, the adsorption part 2102 can use magnetic force to adsorb the snap-fit ​​structure 701, preventing the snap-fit ​​structure 701 from moving and extending to the outside of the display panel 2 after the user controls the display panel 2 to avoid interfering with the fit between the display panel 2 and the instrument mounting platform 1. When the display panel 2 in the horizontal state retracts inward relative to the storage groove 102, a part of the exposed and protruding operating structure 7 on the side wall of the display panel 2 comes into contact with the cleaning layer 5 and generates friction. The driving torque formed by the friction acting on the operating structure 7 is greater than the resisting torque formed by the magnetic adsorption between the adsorption part 2102 and the snap-fit ​​structure 701, so that the operating structure 7 can rotate relative to the guide groove 21 and the adsorption part 2102 is disengaged from the second limiting wall 213.

[0031] refer to Figure 3 , Figure 5 , Figure 10 , Figure 12 An elastic pin 406, which can be a ball screw, is provided on the inner wall of the movable groove 404. A first positioning groove 203104 and a second positioning groove 204104 are offset on the outer wall of the connecting seat 201, and the included angle between the first positioning groove 203104 and the second positioning groove 204104 is 90°. When the display panel 2 is in a horizontal state and is relatively attached to the retracting rod 4, the ball end of the elastic pin 406 abuts against the inner wall of the first positioning groove 203104 to achieve pre-positioning of the display panel 2, thereby helping the display panel 2 maintain a horizontal state. When the display panel 2 is in a vertical state and is relatively perpendicular to the retracting rod 4, the ball end of the elastic pin 406 abuts against the second positioning groove 204104 to achieve pre-positioning of the display panel 2, thereby helping the display panel 2 maintain a vertical state. The driving torque generated by the gravity of the display panel 2 acting on the connector 201 is greater than the resisting torque generated by the clamping force of the elastic pin 406 acting on the connector 201.

[0032] refer to Figure 1 , Figure 9 The instrument mounting platform 1 has a hollow interior forming a storage cavity 106. A retrieval port 107, which communicates with the storage cavity 106, is provided through the side wall of the instrument mounting platform 1. The retrieval port 107 is located above the first latching groove 101, so that after the display panel 2 is stored, the user can retrieve or place items into the storage cavity 106 through the retrieval port 107. When the display panel 2 is unfolded, the latching structure 701 is engaged in the first latching groove 101. The display panel 2 and the side wall of the instrument mounting platform 1 are in contact or clearance fit, so that the display panel 2 covers the retrieval port 107, thereby hiding the retrieval port 107.

[0033] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments.
