Description

Technical Field

[0001] This utility model relates to the technical field of small vulcanizing machines, and more particularly to an in-vehicle display device. Background Technology

[0002] With the rapid development of intelligent in-vehicle devices, in-vehicle displays have become an indispensable part of modern automobiles. In-vehicle displays are typically used to show navigation information, entertainment content, vehicle status information, and more, providing drivers and passengers with a wealth of information services.

[0003] However, existing in-vehicle display devices have the following problems in practical use:

[0004] First, traditional vehicle-mounted display devices are usually fixed in place, with the display screen and the vehicle host integrated into one design. When the display screen malfunctions or needs maintenance, it is often necessary to disassemble the entire device or perform complex disassembly and assembly operations, resulting in high maintenance costs and cumbersome operations.

[0005] Secondly, although some in-vehicle display devices support screen removal, the removal process requires special tools and is complicated, making it difficult for users to complete the disassembly and assembly themselves. They must rely on professional technicians, which increases the inconvenience of use and maintenance.

[0006] Furthermore, existing detachable displays lack effective locking mechanisms, making them prone to loosening or detachment due to vibration or impact during vehicle operation, posing a safety hazard. Additionally, the removal and installation of the displays lack automated assistance, relying entirely on manual operation, resulting in a poor user experience. Utility Model Content

[0007] Technical problems to be solved

[0008] The technical problem this utility model aims to solve is to provide a vehicle-mounted display device. The coordinated operation of the locking mechanism and the telescopic mechanism enables the fully automated removal and installation of the display screen, avoiding the complexity of manual operation. The locking mechanism ensures that the display screen will not be accidentally detached or stolen during vehicle operation. The telescopic mechanism allows the display screen to be completely stored in the housing when not in use, saving interior space. Users can remove and install the display screen without complicated operations, making operation more convenient.

[0009] Technical solution

[0010] The solution adopted by this utility model to solve the above-mentioned technical problems is an in-vehicle display device, including...

[0011] The casing has an opening at its front end;

[0012] A display screen is disposed within the housing, and one end of the display screen is exposed through the opening;

[0013] A locking mechanism, located within the housing, is used to lock or release the display screen;

[0014] A telescopic mechanism, disposed within the housing, is used to drive the display screen to extend out of the housing through the opening or retract into the housing;

[0015] When the display screen needs to be removed, the locking mechanism releases the display screen, and the telescopic mechanism drives the display screen to extend out of the housing through the opening; after the display screen is removed, the telescopic mechanism operates and retracts to its original position; after the display screen is returned to the housing, the locking mechanism operates and locks the display screen.

[0016] Using the above solution, the vehicle display screen can be removed at any time for use as a tablet (such as for outdoor navigation or rear-seat entertainment), and then automatically reset and fixed by the locking mechanism, solving the problem of the single function of traditional vehicle screens; the telescopic mechanism and the locking mechanism work in sequence (unlock first → push out → retract → lock); unlocking before pushing out solves the pain point of "requiring tools to disassemble" vehicle display screens; the automatic reset function of the telescopic mechanism (retracting after removing the display screen) avoids leaving empty slots, meeting the dustproof and waterproof requirements of vehicle equipment; the locking mechanism fixes the display screen by physical engagement (not pure magnetic attraction) when the vehicle is bumpy, combined with the surrounding structure of the receiving slot inside the housing, reducing the risk of unlocking; the telescopic mechanism is completely hidden inside the housing, and the display screen is flush with the housing when it retracts, which is in line with the trend of thinner and lighter vehicle equipment.

[0017] In some embodiments, the locking mechanism includes a first locking member and a second locking member arranged sequentially along the same direction; and the first locking member and the second locking member are capable of moving closer to each other along their arrangement direction to lock the display screen or moving further apart to release the display screen.

[0018] Using the above solution, the locking mechanism uses the relative movement of the first locking member and the second locking member to achieve locking / releasing. Furthermore, when moving towards each other, it applies balanced pressure to both sides of the display screen to ensure that the display screen is subjected to uniform locking force and avoids deformation of the screen frame caused by unilateral force.

[0019] In some embodiments, the first locking member and the second locking member are respectively provided with a first locking part and a second locking part at their ends that are far apart from each other; the display screen is provided with a first locking engagement part that can cooperate with the first locking part and a second locking engagement part that can cooperate with the second locking part at both ends of the arrangement direction of the first locking member and the second locking member.

[0020] In some embodiments, both the first locking engagement portion and the second locking engagement portion are groove structures.

[0021] By adopting the above solution, the concave-convex mating structure of the locking part and the locking mating part ensures the accuracy and repeatability of the display screen installation position.

[0022] In some embodiments, the housing includes an outer frame, a skeleton, and an inner frame arranged sequentially from the outside to the inside; the front end of the outer frame is provided with the opening so that after the outer frame is assembled to the skeleton, a receiving groove for receiving the display screen is formed; a receiving space for receiving the locking mechanism and the telescopic mechanism is formed between the skeleton and the inner frame.

[0023] In some embodiments, the frame is provided with a first opening and a second opening at both ends of the arrangement direction of the first locking member and the second locking member, respectively;

[0024] The first locking member includes a first movable part disposed at the rear of the frame, a first locking part disposed at the front of the frame, and a first connecting part connected between the first movable part and the first locking part. The first connecting part is adapted to the first opening, and the distance between the wall of the first opening and the first connecting part is at least greater than the travel of the first movable part.

[0025] The second locking member includes a second moving part disposed at the rear of the frame, a second locking part disposed at the front of the frame, and a second connecting part connecting the second moving part and the second locking part. The second connecting part is adapted to the second opening, and the distance between the wall of the second opening and the second connecting part is at least greater than the travel of the second moving part.

[0026] By adopting the above scheme, the cooperation between the first opening and the first connecting part, as well as the cooperation between the second opening and the second connecting part, ensures the accuracy of the movement trajectory of the first locking member and the second locking member.

[0027] In some embodiments, a drive motor is further included, the output end of which is connected to a transmission shaft. The transmission shaft includes a drive portion disposed between the first locking member and the second locking member. The drive portion includes a first drive portion and a second drive portion arranged circumferentially spaced apart, the first drive portion and the second drive portion being symmetrically arranged. Furthermore, a first return spring is connected between the first locking member and the housing, and a second return spring is connected between the second locking member and the housing.

[0028] When the drive motor rotates forward, it drives the transmission shaft to rotate forward, causing the drive unit to rotate so that the first drive unit and the second drive unit rotate to abut against the first locking member and the second locking member, and drive the first locking member and the second locking member to move away from each other to release the display screen; when the drive motor rotates in reverse, it drives the transmission shaft to rotate in reverse, causing the drive unit to rotate so that the first drive unit and the second drive unit rotate to disengage from the first locking member and the second locking member, and the first locking member and the second locking member move closer to each other under the restoring force of the first return spring and the second return spring respectively to lock the display screen.

[0029] In some embodiments, one end of the first return spring is fixed to the frame via a fixed shaft, and the other end is fixed to the first moving part of the first locking member via a fixed shaft. The end of the first return spring connected to the frame is closer to the second locking member. One end of the second return spring is fixed to the frame via a fixed shaft, and the other end is fixed to the second moving part of the second locking member via a fixed shaft. The end of the second return spring connected to the frame is closer to the first locking member. This allows the first and second return springs to be stretched after the first and second locking members move away from each other. Then, after the first and second driving parts rotate to disengage from the first and second locking members, the rebound force of the first and second return springs will drive the first and second locking members to move closer to each other and lock the display screen.

[0030] In some embodiments, the first movable part and the second movable part are provided with a hollow structure to install the first return spring and the second return spring; and the first movable part and the second movable part are provided with multiple mounting holes, and the frame is also provided with multiple mounting holes to facilitate the installation of return springs of various specifications.

[0031] In some embodiments, a transmission tooth is connected to the output end of the drive motor, and the transmission shaft is connected to the transmission tooth to realize power transmission; a fixed plate is also connected to the drive motor, and the transmission tooth passes through the fixed plate and is connected to the output end of the drive motor; a limiting part is formed by the protrusion of the outer wall of the transmission tooth, and the fixed plate is provided with an arc-shaped limiting groove for limiting the movement stroke of the limiting part. When the drive motor rotates forward or reverse, it will drive the limiting part to rotate forward or reverse along the limiting groove; the drive motor constrains the rotation angle through the limiting groove (arc-shaped groove + limiting part).

[0032] The above solution has a protruding first drive part and a second drive part to form a cam structure, which divides the movement of the first locking member and the second locking member into a rapid separation section and a stable holding section, ensuring that the first locking member and the second locking member are completely disengaged when the display screen is released; the design of the first return spring and the second return spring allows the first locking member and the second locking member to automatically return to the locked position when there is no motor drive, avoiding the "half-locked" state.

[0033] In some embodiments, the telescopic mechanism includes a telescopic plate disposed in front of the first locking member and the second locking member. The drive motor is capable of driving the telescopic plate to move in the direction of the opening to eject the display screen from the housing; and is capable of driving the telescopic plate to move away from the opening so that the telescopic plate forms a receiving groove for receiving the display screen within the housing.

[0034] In some embodiments, the telescopic plate is disposed opposite to the front end of the frame and is attached to the outer surface of the frame. The telescopic rod of the telescopic plate passes through the frame to realize that the telescopic rod drives the telescopic plate to extend and retract synchronously. In addition, a magnetic attraction structure is provided in the middle of the telescopic plate, and the display screen is attached to the telescopic plate through the magnetic attraction structure to ensure that the display screen and the telescopic plate are tightly attached.

[0035] In some embodiments, the telescopic plate is provided with a sensor for sensing the display screen. After the display screen is removed, a signal is sent to drive the motor to reverse and retract the telescopic plate. After the display screen is placed in, a signal is sent to drive the motor to reverse and enable the first locking member and the second locking member to operate, thereby locking the display screen.

[0036] Using the above solution, the locking and telescopic actions can be controlled simultaneously by the drive motor, simplifying the control system; the telescopic plate forms a receiving groove when it retracts, maximizing the use of the internal space; after the display screen is removed, the sensor triggers the drive motor to reverse, and the telescopic plate automatically retracts, preventing dust accumulation; the locking mechanism will only be activated after the display screen is detected to be fully in place (sensor triggered).

[0037] In some embodiments, a first tooth condition and a second tooth condition are provided behind the first locking member and the second locking member, and the first tooth condition and the second tooth condition are arranged opposite to each other above and below the transmission shaft; a transmission gear portion is provided behind the drive portion of the transmission shaft; a first spur tooth portion and a second spur tooth portion capable of meshing with the transmission gear portion are respectively provided at the ends of the first tooth condition and the second tooth condition that are close to each other, and the drive portion and the transmission gear portion are integrally formed on the transmission shaft.

[0038] In some embodiments, the system further includes two supports fixed to the rear of the frame. One support has a space between it and the frame for the first movable part of the first locking member to move, and the support has a rib to abut against the first movable part. The support also has a first through hole, and the first tooth condition is always placed in the first through hole to further limit the movement of the first tooth condition. The other support has a space between it and the frame for the second movable part of the second locking member to move, and the support has a rib to abut against the second movable part. The support also has a second through hole, and the second tooth condition is always placed in the second through hole to further limit the movement of the second tooth condition.

[0039] Using the above scheme, the transmission shaft integrates a coaxial drive unit and a gear unit, realizing a single drive motor driving two mechanisms (locking mechanism and telescopic mechanism); through the cooperation of the transmission gear unit and the first and second spur gear units, the precise conversion from rotary motion to linear motion is achieved.

[0040] In some embodiments, the first tooth condition and the second tooth condition are respectively provided with a first stroke groove and a second stroke groove at their ends that are far apart from each other in the arrangement direction of the first locking member; at least two telescopic rods are provided behind the telescopic plate, and the two telescopic rods are respectively provided with a first motion shaft placed in the first stroke groove and a second motion shaft placed in the second stroke groove;

[0041] The first travel groove includes a first segment, a second segment, and a third segment arranged sequentially. The first segment and the third segment are linear travel segments. The third segment is arranged close to the first straight tooth portion and is closer to the display screen direction than the first segment. The second segment is an inclined travel segment connecting the first segment and the second segment.

[0042] The second travel groove includes a fourth segment, a fifth segment, and a sixth segment arranged in sequence. The fourth segment and the sixth segment are linear travel segments. The sixth segment is arranged close to the second straight tooth portion and is closer to the display screen direction than the fourth segment. The fifth segment is an inclined travel segment connecting the fourth segment and the sixth segment.

[0043] During the process where the drive motor rotates forward to drive the transmission shaft to rotate forward, and drives the drive unit and the transmission gear unit to rotate synchronously forward; the drive unit is rotated so that the first drive unit and the second drive unit rotate to abut against the first locking member and the second locking member, and drive the first locking member and the second locking member to move in a direction away from each other to release the display screen; the transmission gear unit rotates and drives the first gear condition and the second gear condition to move in a direction away from each other, and during this process, the first motion shaft is always placed in the first segment, and the second motion shaft is always placed in the fourth segment;

[0044] After the first and second locking members release the display screen, the drive motor continues to rotate forward, driving the drive unit and the transmission gear unit to rotate forward synchronously. The first and second drive units are in a resisting state with the first and second locking members. The first and second gears continue to move in a direction away from each other. The first motion shaft enters the second section and moves along the second section, and the second motion shaft enters the fifth section and moves along the fifth section, so that the telescopic rod and the telescopic plate are driven to move towards the opening to push the display screen out of the housing. When the first motion shaft enters the third section and the second motion shaft enters the fifth section, the telescopic rod and the telescopic plate stop extending, and the display screen is just fully extended.

[0045] After the display screen is removed, the drive motor reverses and drives the transmission shaft to reverse, which in turn drives the drive unit and the transmission gear unit to reverse synchronously. The first drive unit and the second drive unit are in abutting state with the first locking member and the second locking member. The first gear condition and the second gear condition continue to move towards each other. The first motion shaft enters the second section and moves along the second section. The second motion shaft enters the fifth section and moves along the fifth section, so that the telescopic rod and the telescopic plate are driven to move away from the opening. When the first motion shaft enters the first section and the second motion shaft enters the fourth section, the drive motor stops running, so that the telescopic plate forms a receiving groove for receiving the display screen in the housing.

[0046] After the display screen is placed into the receiving slot, the drive motor reverses and drives the transmission shaft to reverse, which in turn drives the drive unit and the transmission gear unit to reverse synchronously. The first drive unit and the second drive unit rotate until they disengage from the first locking member and the second locking member. Under the restoring force of the first return spring and the second return spring, the first locking member and the second locking member move closer to each other to lock the display screen, and the drive motor stops running.

[0047] In some embodiments, two vertically arranged telescopic rods are provided on one side of the telescopic plate, with the two telescopic rods positioned opposite each other above and below the first tooth condition, and both ends of the first motion shaft are fixed inside the two telescopic rods; two vertically arranged telescopic rods are provided on the other side of the telescopic plate, with the two telescopic rods positioned opposite each other above and below the second tooth condition, and both ends of the second motion shaft are fixed inside the two telescopic rods.

[0048] Using the above scheme, a three-segment travel groove design achieves precise timing coordination control of the vehicle display telescopic mechanism and the locking mechanism, enabling locking-extension-retraction-locking. In the first stage (unlocking): the first motion shaft remains stationary in the first segment's linear groove, and the second motion shaft remains stationary in the fourth segment's linear groove. At this time, the movement of the first and second tooth conditions only drives the separation of the first and second locking components; the telescopic plate does not move. In the second stage (extension): the first motion shaft enters the second segment's inclined section, and the second motion shaft enters the fifth segment's inclined section, converting the horizontal movement of the first and second tooth conditions into the telescopic movement of the telescopic rod. In the third stage (reset): the third / sixth segment's linear groove is synchronized with the reset of the first and second locking components, ensuring that the telescopic mechanism only begins to extend (second / fifth segment) after the locking mechanism is fully unlocked (first / fourth segment completed), and also ensuring that the locking mechanism only closes after the display screen is fully retracted.

[0049] In some embodiments, the driving portion includes a shaft portion, and a first driving portion and a second driving portion formed by outwardly protruding ends opposite to the shaft portion; the first driving portion includes a first arcuate transition portion extending between the shaft portion and a first arcuate portion connecting with the first arcuate transition portion, and the second driving portion includes a second arcuate transition portion extending between the shaft portion and a second arcuate portion connecting with the second arcuate transition portion; the first arcuate portion has a greater extension distance in the radial direction relative to the first arcuate transition portion, forming a convex contour feature; the second arcuate portion has a greater extension distance in the radial direction relative to the second arcuate transition portion, forming a convex contour feature; the first locking member and the second locking member are respectively provided with a first arcuate protrusion and a second arcuate protrusion at their respective ends close to each other;

[0050] Furthermore, during the rotation of the drive unit to the point where the first arc-shaped protrusion moves from the shaft portion along the first arc-shaped transition portion to the first arc portion and the second arc-shaped protrusion moves from the shaft portion along the second arc-shaped transition portion to the second arc portion, the first locking member and the second locking member move away from each other until the display screen is completely released; during the operation of the drive motor driving the telescopic plate to move towards the opening, the first arc-shaped protrusion moves away from the first arc-shaped transition portion along the first arc portion, and the second arc-shaped protrusion moves away from the second arc-shaped transition portion along the second arc portion; during the operation of the drive motor driving the telescopic plate to move away from the opening, the first arc-shaped protrusion moves towards the first arc-shaped transition portion along the first arc portion, and the second arc-shaped protrusion moves towards the second arc-shaped transition portion along the second arc portion; when the drive unit rotates to the point where the first arc-shaped protrusion moves from the first arc portion along the first arc-shaped transition portion to the shaft portion and the second arc-shaped protrusion moves from the second arc portion along the second arc-shaped transition portion to the shaft portion, the first locking member and the second locking member move closer to each other until the display screen is completely locked.

[0051] In some embodiments, the size of the first opening for the first connecting portion to move is sufficient to allow the first arcuate protrusion to move to the most protruding part of the first arcuate portion; the size of the second opening for the second connecting portion to move is sufficient to allow the second arcuate protrusion to move to the most protruding part of the second arcuate portion.

[0052] Using the above scheme, the first and second arc-shaped transition portions provide a smooth force transmission transition, enabling the first and second locking members to achieve progressive movement; the first and second arc-shaped portions provide stable support when the first and second locking members are fully released, ensuring that the first and second locking members remain stable in the correct position, providing a reliable foundation for subsequent telescopic movements; during the rotation of the drive unit, the first arc-shaped protrusion moves from the shaft portion along the first arc-shaped transition portion to the first arc-shaped portion, and the second arc-shaped protrusion moves from the shaft portion along the second arc-shaped transition portion to the second arc-shaped portion, driving the first and second locking members to completely separate. During this process, the first motion shaft remains stationary within the straight groove of the first section, while the second motion shaft... The telescopic plate remains stationary within the straight groove of the fourth segment and does not move. The first arc-shaped protrusion moves along the first arc portion, and the second arc-shaped protrusion moves along the second arc portion. The first and second locking members remain unlocked. During this process, the first motion shaft is in the inclined section of the second segment, and the second motion shaft is in the inclined section of the fifth segment. The telescopic plate extends / retracts. The first arc-shaped protrusion moves from the first arc portion along the first arc transition portion to the shaft portion, and the second arc-shaped protrusion moves from the second arc portion along the second arc transition portion to the shaft portion. The first and second locking members approach and lock the display screen. During this process, the first motion shaft remains stationary within the straight groove of the first segment, and the second motion shaft remains stationary within the straight groove of the fourth segment. The telescopic plate does not move. Beneficial effects

[0082] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0083] like Figures 1-13As shown, this utility model provides a vehicle-mounted display device, including a housing 100 with an opening 101 at its front end; a display screen 200 disposed within the housing 100, with one end of the display screen 200 protruding through the opening 101; a locking mechanism 300 disposed within the housing 100 for locking or releasing the display screen 200; and a telescopic mechanism 400 disposed within the housing 100 for driving the display screen 200 to extend out of the housing 100 through the opening 101 or retract into the housing 100. When the display screen 200 needs to be removed, the locking mechanism 300 operates to release the display screen 200, and then the telescopic mechanism 400 operates to drive the display screen 200 to extend out of the housing 100 through the opening 101. After the display screen 200 is removed, the telescopic mechanism 400 operates and retracts to its original position. After the display screen 200 is returned to the housing 100, the locking mechanism 300 operates and locks the display screen 200. Using the above solution, the vehicle display screen 200 can be removed at any time for use as a tablet (such as for outdoor navigation or rear-seat entertainment), and then automatically reset and fixed by the locking mechanism 300, solving the problem of the single function of traditional vehicle screens; the telescopic mechanism 400 and the locking mechanism 300 work in sequence (unlock first → push out → retract → lock); the unlocking before pushing out solves the pain point of the vehicle display screen 200 "requiring tool disassembly"; the automatic reset function of the telescopic mechanism 400 (retracting after removing the display screen 200) avoids leaving empty slots, meeting the dustproof and waterproof requirements of vehicle equipment; the locking mechanism 300 fixes the display screen 200 by physical engagement (not pure magnetic attraction) when the vehicle is bumpy, and combined with the surrounding structure of the receiving slot 104 in the housing 100, it reduces the risk of unlocking; the telescopic mechanism 400 is completely hidden inside the housing 100, and the display screen 200 is flush with the housing 100 when it retracts, which is in line with the trend of thinner and lighter vehicle equipment.

[0084] In some embodiments, the locking mechanism 300 includes a first locking member 301 and a second locking member 302 arranged sequentially along the same direction; and the first locking member 301 and the second locking member 302 can move closer to each other along their arrangement direction to lock the display screen 200 or move further apart to release the display screen 200. Using the above scheme, the locking mechanism 300 achieves locking / releasing through relative movement of the first locking member 301 and the second locking member 302, and when moving towards each other, applies balanced pressure to both sides of the display screen 200, ensuring that the display screen 200 is subjected to uniform locking force and avoiding deformation of the screen frame caused by unilateral force. In some embodiments, a first locking portion 3011 and a second locking portion 3021 are respectively provided at the ends of the first locking member 301 and the second locking member 302 that are far apart from each other; the display screen 200 is provided at both ends located along the arrangement direction of the first locking member 301 and the second locking member 302 with a first locking engagement portion 201 that can cooperate with the first locking portion 3011 and a second locking engagement portion 202 that can cooperate with the second locking portion 3021. In some embodiments, both the first locking engagement portion 201 and the second locking engagement portion 202 are groove structures. Using the above solution, the concave-convex engagement structure of the locking portion and the locking engagement portion ensures the accuracy and reproducibility of the installation position of the display screen 200.

[0085] In some embodiments, the housing 100 includes an outer frame 102, a skeleton 103, and an inner frame arranged sequentially from the outside to the inside; the front end of the outer frame 102 is provided with the opening 101, so that after the outer frame 102 is assembled to the skeleton 103, a receiving groove 104 for receiving the display screen 200 is formed; a receiving space for receiving the locking mechanism 300 and the telescopic mechanism 400 is formed between the skeleton 103 and the inner frame. In some embodiments, the skeleton 103 is provided with a first opening 1031 and a second opening 1032 at both ends of the arrangement direction of the first locking member 301 and the second locking member 302, respectively; the first locking member 301 includes a first moving part 3012 arranged at the rear of the skeleton 103, a first locking part 3011 arranged at the front end of the skeleton 103, and a first connecting part 3013 connecting the first moving part 3012 and the first locking part 3011, the first connecting part 3013 being adapted to the first opening 1031, and the wall of the first opening 1031 and the first locking part 402 being connected to the first locking member 302. The distance between the connecting portions 3013 is at least greater than the travel distance of the first moving portion 3012; the second locking member 302 includes a second moving portion 3022 disposed behind the frame 103, a second locking portion 3021 disposed at the front end of the frame 103, and a second connecting portion 3023 connecting the second moving portion 3022 and the second locking portion 3021. The second connecting portion 3023 is adapted to the second opening 1032, and the distance between the wall of the second opening 1032 and the second connecting portion 3023 is at least greater than the travel distance of the second moving portion 3022. Using the above scheme, the cooperation between the first opening 1031 and the first connecting portion 3013, and the cooperation between the second opening 1032 and the second connecting portion 3023, ensure the accuracy of the movement trajectories of the first locking member 301 and the second locking member 302.

[0086] In some embodiments, a drive motor 500 is further included, the output end of which is connected to a transmission shaft 501. The transmission shaft 501 includes a drive portion 5011 disposed between the first locking member 301 and the second locking member 302. The drive portion 5011 includes a first drive portion 5012 and a second drive portion 5013 arranged circumferentially spaced apart, the first drive portion 5012 and the second drive portion 5013 being symmetrically arranged. A first return spring 303 is connected between the first locking member 301 and the housing 100, and a second return spring 304 is connected between the second locking member 302 and the housing 100. When the drive motor 500 rotates forward, driving the transmission shaft 501 to rotate forward, the drive... Part 5011 is driven to rotate, causing the first driving part 5012 and the second driving part 5013 to rotate to abut against the first locking member 301 and the second locking member 302, and driving the first locking member 301 and the second locking member 302 to move away from each other to release the display screen 200; when the drive motor 500 reverses and drives the transmission shaft 501 to reverse, the driving part 5011 is driven to rotate, causing the first driving part 5012 and the second driving part 5013 to rotate to disengage from the first locking member 301 and the second locking member 302, and the first locking member 301 and the first locking member 301 respectively approach each other under the restoring force of the first return spring 303 and the second return spring 304 to lock the display screen 200. In some embodiments, one end of the first return spring 303 is fixed to the frame 103 by a fixed shaft, and the other end is fixed to the first moving part 3012 of the first locking member 301 by a fixed shaft. The end of the first return spring 303 connected to the frame 103 is closer to the second locking member 302. One end of the second return spring 304 is fixed to the frame 103 by a fixed shaft, and the other end is fixed to the second moving part 3022 of the second locking member 302 by a fixed shaft. The end of the second return spring 304 connected to the frame 103 is closer to the first locking member 301. This allows the first return spring 303 and the second return spring 304 to be stretched after the first locking member 301 and the second locking member 302 move away from each other. Then, after the first driving part 5012 and the second driving part 5013 rotate to disengage from the first locking member 301 and the second locking member 302, the rebound force of the first return spring 303 and the second return spring 304 will drive the first locking member 301 and the second locking member 302 to move closer to each other and lock the display screen 200. In some embodiments, the first moving part 3012 and the second moving part 3022 are provided with a hollow structure to install the first return spring 303 and the second return spring 304; and the first moving part 3012 and the second moving part 3022 are provided with a plurality of mounting holes, and the frame 103 is also provided with a plurality of mounting holes to facilitate the installation of return springs of various specifications.In some embodiments, a transmission gear 502 is connected to the output end of the drive motor 500, and the transmission shaft 501 is connected to the transmission gear 502 to realize power transmission; a fixing plate 503 is also connected to the drive motor 500, and the transmission gear 502 passes through the fixing plate 503 and is connected to the output end of the drive motor 500; a limiting part 5021 is formed by protrusions on the outer wall of the transmission gear 502, and the fixing plate 503 is provided with an arc-shaped limiting groove 5031 for limiting the movement stroke of the limiting part 5021. When the drive motor 500 rotates forward or reverse, it will drive the limiting part 5021 to rotate forward or reverse along the limiting groove 5031; the drive motor 500 constrains the rotation angle through the limiting groove 5031 (arc-shaped groove + limiting part 5021). Using the above scheme, the drive unit 5011 has a protruding first drive unit 5012 and a second drive unit 5013 to form a cam structure, so that the movement of the first locking member 301 and the second locking member 302 is divided into a rapid separation section and a stable holding section, ensuring that the first locking member 301 and the second locking member 302 are completely disengaged when the display screen 200 is released; the design of the first return spring 303 and the second return spring 304 makes the first locking member 301 and the second locking member 302 automatically return to the locked position when there is no motor drive, avoiding the "half-locked" state.

[0087] In some embodiments, the telescopic mechanism 400 includes a telescopic plate 401 disposed in front of the first locking member 301 and the second locking member 302. The drive motor 500 can drive the telescopic plate 401 to move towards the opening 101 to eject the display screen 200 from the housing 100; and can drive the telescopic plate 401 to move away from the opening 101 so that the telescopic plate 401 forms a receiving groove 104 for receiving the display screen 200 within the housing 100. In some embodiments, the telescopic plate 401 is disposed opposite to the front end of the frame 103 and is in contact with the outer surface of the frame 103. The telescopic rod 402 of the telescopic plate 401 passes through the frame 103 to realize that the telescopic rod 402 drives the telescopic plate 401 to extend and retract synchronously; and a magnetic attraction structure 406 is provided in the middle of the telescopic plate 401. The display screen 200 is attracted to the telescopic plate 401 through the magnetic attraction structure 406 to ensure a tight fit between the display screen 200 and the telescopic plate 401. In some embodiments, the telescopic plate 401 is provided with a sensor 405 for sensing the display screen 200. After the display screen 200 is removed, a signal is sent to drive the motor 500 to reverse and retract the telescopic plate 401. After the display screen 200 is placed in, a signal is sent to drive the motor 500 to reverse and enable the first locking member 301 and the second locking member 302 to operate, thereby locking the display screen 200. With the above scheme, the locking and telescopic actions can be controlled simultaneously by the drive motor 500, simplifying the control system. When the telescopic plate 401 retracts, it forms a receiving groove 104, maximizing the use of internal space. After the display screen 200 is removed, the sensor 405 triggers the drive motor 500 to reverse, and the telescopic plate 401 automatically retracts, preventing dust accumulation. The locking mechanism 300 will only be activated after the display screen 200 is detected to be fully in place (triggered by the sensor 405).

[0088] In some embodiments, a first tooth condition 600 and a second tooth condition 700 are provided behind the first locking member 301 and the second locking member 302, and the first tooth condition 600 and the second tooth condition 700 are arranged opposite to each other above and below the drive shaft 501; a transmission gear portion 5014 is provided behind the drive portion 5011 on the drive shaft 501; a first spur tooth portion 601 and a second spur tooth portion 701 that can mesh with the transmission gear portion 5014 are respectively provided at the ends of the first tooth condition 600 and the second tooth condition 700 that are close to each other, and the drive portion 5011 and the transmission gear portion 5014 are integrally formed on the drive shaft 501. In some embodiments, the system further includes two brackets 800 fixed to the rear of the frame 103. One bracket 800 has a space between it and the frame 103 for the first moving part 3012 of the first locking member 301 to move. The bracket 800 is provided with a rib to abut against the first moving part 3012. The bracket 800 is also provided with a first through hole 801. The first tooth condition 600 is always placed in the first through hole 801, further limiting the movement of the first tooth condition 600. The other bracket 800 has a space between it and the frame 103 for the second moving part 3022 of the second locking member 302 to move. The bracket 800 is provided with a rib to abut against the second moving part 3022. The bracket 800 is also provided with a second through hole 802. The second tooth condition 700 is always placed in the second through hole 802, further limiting the movement of the second tooth condition 700. Using the above scheme, the transmission shaft 501 integrates the coaxial drive unit 5011 and the gear unit, realizing the driving of two mechanisms (locking mechanism 300 and telescopic mechanism 400) by one drive motor 500; through the cooperation of the transmission gear unit 5014 and the first spur gear unit 601 and the second spur gear unit 701, the precise conversion from rotary motion to linear motion is realized. In some embodiments, the first tooth condition 600 and the second tooth condition 700 are respectively provided with a first travel groove 602 and a second travel groove 702 at their ends that are far apart from each other in the arrangement direction of the first locking member 301; at least two telescopic rods 402 are provided behind the telescopic plate 401, and the two telescopic rods 402 are respectively provided with a first motion shaft 403 placed in the first travel groove 602 and a second motion shaft 404 placed in the second travel groove 702; the first travel groove 602 includes a first segment 6021, a second segment 6022 and a third segment 6023 arranged in sequence, the first segment 6021 and the third segment 6023 are linear travel, the third segment 6023 is arranged close to the first straight tooth portion 601, and the third segment 6023 is closer to the display screen 200 direction than the first segment 6021; the second segment 6022 is an inclined travel connecting the first segment 6021 and the second segment 6022.The second travel groove 702 includes a fourth segment 7021, a fifth segment 7022, and a sixth segment 7023 arranged sequentially. The fourth segment 7021 and the sixth segment 7023 are linear travel segments. The sixth segment 7023 is arranged close to the second spur gear portion 701 and is closer to the display screen 200 than the fourth segment 7021. The fifth segment 7022 is an inclined travel segment connecting the fourth segment 7021 and the sixth segment 7023. The drive motor 500 drives the transmission shaft 501 to rotate forward, and drives the drive unit 5011 and the transmission gear unit 5014 to rotate forward synchronously. The drive unit 501... 1 is rotated so that the first drive unit 5012 and the second drive unit 5013 rotate to abut against the first locking member 301 and the second locking member 302, and drive the first locking member 301 and the second locking member 302 to move in a direction away from each other to release the display screen 200; the transmission gear unit 5014 rotates and drives the first gear condition 600 and the second gear condition 700 to move in a direction away from each other, and in this process, the first motion shaft 403 is always placed in the first segment 6021, and the second motion shaft 404 is always placed in the fourth segment 7021; the first locking member 301 and the second locking member 302 release the display screen 200. After 00, the drive motor 500 continues to rotate forward, driving the drive unit 5011 and the transmission gear unit 5014 to rotate synchronously forward. The first drive unit 5012 and the second drive unit 5013 are in abutting state with the first locking member 301 and the second locking member 302. The first gear condition 600 and the second gear condition 700 continue to move in a direction away from each other. The first motion shaft 403 enters the second segment 6022 and moves along the second segment 6022. The second motion shaft 404 enters the fifth segment 7022 and moves along the fifth segment 7022, so that the telescopic rod 402 and the telescopic plate 401 are driven to move closer to the opening. The first drive shaft 403 moves in the direction of 101 to push the display screen 200 out of the housing 100 until the first drive shaft 403 enters the third segment 6023 and the second drive shaft 404 enters the fifth segment 7022. At this point, the telescopic rod 402 and the telescopic plate 401 stop extending, and the display screen 200 is fully extended. After the display screen 200 is removed, the drive motor 500 reverses and drives the transmission shaft 501 to reverse, which in turn drives the drive unit 5011 and the transmission gear unit 5014 to reverse synchronously. The first drive unit 5012 and the second drive unit 5013 are in a resisting state with the first locking member 301 and the second locking member 302.The first tooth condition 600 and the second tooth condition 700 continue to move toward each other. The first motion shaft 403 enters the second segment 6022 and moves along the second segment 6022. The second motion shaft 404 enters the fifth segment 7022 and moves along the fifth segment 7022, so that the telescopic rod 402 and the telescopic plate 401 are driven to move away from the opening 101. When the first motion shaft 403 enters the first segment 6021 and the second motion shaft 404 enters the fourth segment 7021, the drive motor 500 stops running, so that the telescopic plate 401 forms a retractable shape within the housing 100. The display screen 200 is placed in the receiving slot 104; after the display screen 200 is placed in the receiving slot 104, the drive motor 500 reverses, drives the transmission shaft 501 to reverse, and drives the drive part 5011 and the transmission gear part 5014 to reverse synchronously; the first drive part 5012 and the second drive part 5013 rotate until they disengage from the first locking member 301 and the second locking member 302, and the first locking member 301 and the second locking member 302 move closer to each other under the restoring force of the first return spring 303 and the second return spring 304 respectively until they lock the display screen 200, and the drive motor 500 stops running.

[0089] In some embodiments, two vertically arranged telescopic rods 402 are provided on one side of the telescopic plate 401, with the two telescopic rods 402 positioned opposite each other at the top and bottom of the first tooth condition 600, and both ends of the first motion shaft 403 are fixed inside the two telescopic rods 402; two vertically arranged telescopic rods 402 are provided on the other side of the telescopic plate 401, with the two telescopic rods 402 positioned opposite each other at the top and bottom of the second tooth condition 700, and both ends of the second motion shaft 404 are fixed inside the two telescopic rods 402. Using the above scheme, through the three-segment travel groove design, precise timing coordination control of the locking-extension-retraction-locking of the telescopic mechanism 400 and the locking mechanism 300 of the vehicle display screen 200 is achieved; First stage (unlocking): The first motion shaft 403 is stationary in the linear groove of the first segment 6021, and the second motion shaft 404 is stationary in the linear groove of the fourth segment 7021. At this time, the movement of the first tooth condition 600 and the second tooth condition 700 only drives the separation of the first locking member 301 and the second locking member 302, and the telescopic plate 401 does not move; Second stage (extension): The first motion shaft 403 enters the tilting section of the second segment 6022. Within the inclined section, the second motion shaft 404 enters the inclined section of the fifth segment 7022, converting the horizontal movement of the first tooth condition 600 and the second tooth condition 700 into the telescopic movement of the telescopic rod 402; in the third stage (reset): the linear groove of the third segment 6023 / sixth segment 7023 is synchronized with the reset of the first locking member 301 and the second locking member 302, ensuring that the telescopic mechanism 400 only begins to extend (second segment 6022 / fifth segment 7022) after the locking mechanism 300 is fully unlocked (first segment 6021 / fourth segment 7021 is completed), and also ensuring that the locking mechanism 300 only closes after the display screen 200 is fully retracted.In some embodiments, the drive portion 5011 includes a shaft portion 5015, and a first drive portion 5012 and a second drive portion 5013 formed by outwardly protruding two opposite ends of the shaft portion 5015; the first drive portion 5012 includes a first arcuate transition portion 5012a extending between the shaft portion 5015 and a first arcuate portion 5012b connected to the first arcuate transition portion 5012a; the second drive portion 5013 includes a second arcuate transition portion 5013a extending between the shaft portion 5015 and a second arcuate portion 5013b connected to the second arcuate transition portion 5013a; the first arcuate portion 5012b is opposite to the first arcuate transition portion 5012a. The transition portion 5012a has a greater extension distance in the radial direction, forming a convex contour feature; the second arc portion 5013b has a greater extension distance in the radial direction relative to the second arc transition portion 5013a, forming a convex contour feature; the first locking member 301 and the second locking member 302 are respectively provided with a first arc protrusion 3014 and a second arc protrusion 3024 at their respective ends close to each other; and, when the driving part 5011 rotates to the point where the first arc protrusion 3014 moves along the first arc transition portion 5012a by the shaft portion 5015 to the first arc portion 5012b and the second arc protrusion 3024 move along the second arc transition portion 5012a by the shaft portion 5015, the first arc portion 5012b and the second arc protrusion 3024 move along the second arc transition portion 5012a by the shaft portion 5015. During the movement of the arc-shaped transition portion 5013a to the second arc portion 5013b, the first locking member 301 and the second locking member 302 move away from each other until the display screen 200 is completely released; during the operation of the drive motor 500 driving the telescopic plate 401 to move towards the opening 101, the first arc-shaped protrusion 3014 moves away from the first arc-shaped transition portion 5012a along the first arc portion 5012b, and the second arc-shaped protrusion moves away from the second arc-shaped transition portion 5013a along the second arc portion 5013b; during the operation of the drive motor 500 driving the telescopic plate 401 to move away from the opening 101... In the process, the first arc-shaped protrusion 3014 moves along the first arc portion 5012b to approach the first arc-shaped transition portion 5012a, and the second arc-shaped protrusion moves along the second arc portion 5013b to approach the second arc-shaped transition portion 5013a; when the drive portion 5011 rotates to the point where the first arc-shaped protrusion 3014 moves from the first arc portion 5012b along the first arc-shaped transition portion 5012a to the shaft portion 5015 and the second arc-shaped protrusion 3024 moves from the second arc portion 5013b along the second arc-shaped transition portion 5013a to the shaft portion 5015, the first locking member 301 and the second locking member 302 move closer to each other to completely lock the display screen 200.In some embodiments, the size of the first opening 1031 for the first connecting portion 3013 to move is sufficient to allow the first arcuate protrusion 3014 to move to the most protruding part of the first arcuate portion 5012b; the size of the second opening 1032 for the second connecting portion 3023 to move is sufficient to allow the second arcuate protrusion 3024 to move to the most protruding part of the second arcuate portion 5013b. Using the above scheme, the first arcuate transition portion 5012a and the second arcuate transition portion 5013a provide a smooth force transmission transition, enabling the first locking member 301 and the second locking member 302 to achieve progressive movement; the first arcuate portion 5012b and the second arcuate portion 5013b provide stable support when the first locking member 301 and the second locking member 302 are fully released, ensuring that the first locking member 301 and the second locking member 302 remain stable in the correct position, providing a reliable foundation for subsequent telescopic movements; in the driving...
