[0043] The following uses Figures 2 to 17 This invention describes a preferred embodiment of the vehicle-mounted display device according to the present invention.

[0044] like Figure 2 and Figures 3A to 3C As shown, the vehicle-mounted display device includes a display screen 1, a base plate 5, a top cover plate 12, and two symmetrically arranged side brackets 21, each side bracket 21 being provided with a guide mechanism. More specifically, in this embodiment, the guide mechanism includes, for example, a first guide member 23 and a second guide member 25 fixedly connected to each side bracket 21. The first guide member 23 is provided with a straight guide groove 231 (see reference). Figure 9 The second guide member 25 is provided with a curved guide groove (see reference). Figures 6A to 6C The curved guide groove includes a straight segment 251 parallel to the straight guide groove 231 and a curved segment 252 (e.g., an arc segment) extending from the end of the straight segment 251. The top of each side bracket 21 is connected to the upper cover plate 12, and the bottom of each side bracket 21 is connected to the base plate 5, for example, via a second guide member 25, thereby integrally forming the housing of the vehicle-mounted display device. This housing defines a cavity for accommodating the display screen 1, and one end of the housing has an opening H for the display screen 1 to extend out of the cavity.

[0045] In addition, the vehicle-mounted display device also includes a transmission arm assembly, a cable assembly, and a drive mechanism for moving the display screen 1 between a retracted position and an extended position, and between an extended position and a usage position. The display screen 1 is flat; in the retracted position, it is completely retracted into the cavity of the housing and arranged parallel to its translational direction; in the extended position, it is completely extended out of the cavity of the housing and arranged parallel to its translational direction; and in the usage position, it is completely extended out of the cavity of the housing and flipped to face the user for viewing and operation.

[0046] More specifically, in this embodiment, as Figure 2 , Figures 6A to 6Cas well as Figure 9 As shown, the transmission arm assembly includes a first transmission arm 2, a second transmission arm 3, and a connecting rod 26. The first end 201 of the first transmission arm 2 is hinged to the display screen 1, and the second end 202 of the first transmission arm 2 is hinged to the first hinged end 261 of the connecting rod 26. One end 301 of the second transmission arm 3 is hinged to the display screen 1, and the second transmission arm 3 is hinged to the second hinged end 262 of the connecting rod 26 via a hinged portion 302. Furthermore, the second transmission arm 3 is provided with a first sliding portion, such as a slider 303, capable of sliding along a straight guide groove 231, and the connecting rod 26 is provided with a second sliding portion, such as a sliding pin 263, capable of sliding along the straight segment 251 and the curved segment 252 of a curved guide groove.

[0047] like Figure 2 , Figures 4A to 4C as well as Figure 7A and Figure 7B As shown, the cable assembly includes a reel 15, a reversing disc 6, and a cable. The cable is wound around both the reel 15 and the reversing disc 6 and connected to the drive arm assembly. More specifically, in this embodiment, the cable assembly includes a first cable 10, a second cable 11, a cable bracket 19, a pressure cap 20, and two first elastic elements 27 (e.g., springs). The cable bracket 19 is fixedly connected to the connecting portion 304 of the second drive arm 3 and is provided with a first receiving cavity 191 and a second receiving cavity 192. The first end of the first cable 10 is provided with a first end 101 that is received in the first receiving cavity 191, so as to be connected to the second drive arm 3 through the first end 101 and the cable bracket 19, and the second end of the first cable 10 is provided with a second end 102 that is fixedly connected to the reel 15. The first end of the second pull cable 11 is provided with a third end 111 that is accommodated in the second accommodating cavity 192, and is connected to the second transmission arm 3 through the third end 111 and the pull cable bracket 19. The second end of the second pull cable 11 is provided with a fourth end 112 that is fixedly connected to the winding reel 15. A first elastic member 27 is accommodated in the first accommodating cavity 191 and is elastically compressed between the cavity wall of the first accommodating cavity 191 and the first end 101. Another first elastic member 27 is accommodated in the second accommodating cavity 192 and is elastically compressed between the cavity wall of the second accommodating cavity 192 and the third end 111. Thus, by pressing the first end 101 and the third end 111 against the cavity walls of the first accommodating cavity 191 and the second accommodating cavity 192 respectively, the first pull cable 10 and the second pull cable 11 are always kept taut. The pressure cap 20 is fixedly connected to the pull cable bracket 19 and is used to hold the two first elastic members 27 in the first accommodating cavity 191 and the second accommodating cavity 192 respectively.

[0048] The drive mechanism is, for example, a motor 16 connected to a winding reel 15. More specifically, in this embodiment, such as Figure 2 , Figures 4A to 4C as well as Figure 8 As shown, the motor assembly of the vehicle-mounted display device includes a support plate 14, a motor 16, and a motor bracket 17. The motor 16 is mounted to the motor bracket 17, which is fixedly connected to the top surface of the support plate 14. The support plate 14 is fixedly connected to the upper cover plate 12. A cable reel 15 is mounted to a first mounting base 13, which is fixedly connected to the bottom surface of the support plate 14. This allows the motor shaft 161 of the motor 16 to pass through the support plate 14 and connect to the cable reel 15, enabling the cable reel 15 to rotate around its central axis when the motor shaft 161 rotates. Furthermore, a steering wheel 6 is mounted to a second mounting base 7, which is fixedly connected to the upper cover plate 12.

[0049] When it is necessary to move the display screen 1 from the storage position to the use position, the motor 16 drives the reel 15 along the first direction (i.e., Figure 7A The first pull cable 10, which is reversed by the reversing disc 6, is wound around the reel 15 via its second end 102, while the second pull cable 11 is unwound around the reel 15 via its fourth end 112. The movement of the first end 101 of the first pull cable 10 and the third end 111 of the second pull cable 11 then moves the cable support 19 and the second transmission arm 3. At this time, the slider 303 on the second transmission arm 3 slides along the straight guide groove 231, and the sliding pin 263 on the connecting rod 26 slides along the straight section 251 of the curved guide groove, thereby moving the display screen 1 from the retracted position to the extended position. Then, the slider 303 on the second transmission arm 3 continues to slide along the straight guide groove 231, and the sliding pin 263 on the connecting rod 26 slides along the curved section 252 of the curved guide groove, thereby flipping the display screen 1 from the extended position to the usage position.

[0050] When it is necessary to move the display screen 1 from the usage position to the storage position, the motor 16 drives the reel 15 along a second direction opposite to the first direction (i.e., ... Figure 7A The clockwise rotation of the first pull cable 10, which is redirected by the reversing disc 6, causes the first pull cable 10 to unwind around the reel 15 via its second end 102, while the second pull cable 11 winds up around the reel 15 via its fourth end 112. The movement of the first end 101 of the first pull cable 10 and the third end 111 of the second pull cable 11 then moves the cable support 19 and the second transmission arm 3. At this time, the slider 303 on the second transmission arm 3 slides along the straight guide groove 231, and the sliding pin 263 on the connecting rod 26 slides along the curved segment 252 of the curved guide groove, thereby causing the display screen 1 to flip from the use position to the extended position. Then, the slider 303 on the second transmission arm 3 continues to slide along the straight guide groove 231, and the sliding pin 263 on the connecting rod 26 slides along the straight segment 251 of the curved guide groove, thereby causing the display screen 1 to translate from the extended position to the retracted position.

[0051] like Figures 5A to 5C As shown, in this embodiment, the vehicle-mounted display device preferably also includes a third elastic element 28 (e.g., a torsion spring). More specifically, the third elastic element 28 is sleeved on a mounting shaft 29 to be disposed on the back side of the display screen 1 via the mounting shaft 29. The first end 281 of the third elastic element 28 is connected to the back side of the display screen 1, and the second end 282 of the third elastic element 28 is connected to the first transmission arm 2. During the process of the display screen 1 flipping from the use position to the extended position, the third elastic element 28 is compressed and stores energy due to the relative rotation of the display screen 1 and the first transmission arm 2. During the process of the display screen 1 flipping from the extended position to the use position, the third elastic element 28 can assist in pushing the display screen 1 to overcome its own gravity and flip from the extended position to the use position by releasing elastic potential energy during the relative rotation of the display screen 1 and the first transmission arm 2.

[0052] like Figure 10A and Figure 10B As shown, the vehicle-mounted display device also preferably includes a cable chain 9 with a curved structure through which the power supply wire connected to the display screen 1 passes. The cable chain 9 is connected to the transmission arm assembly to move with the transmission arm assembly along the translational direction of the display screen 1, serving to protect the wire and prevent it from becoming entangled, worn, or broken as it moves with the display screen 1. More specifically, in this embodiment, the vehicle-mounted display device includes a third guide member 8 and a cable chain bracket 18. One end 901 of the cable chain 9 is connected to the second transmission arm 3, for example, below the cable support 19, via the cable chain bracket 18, so that the movement of the second transmission arm 3 can drive the cable chain 9 to move. The two sidewalls 801 of the third guide member 8 define guide grooves for guiding the cable chain 9 to move along the translational direction of the display screen 1.

[0053] like Figures 11A to 17 As shown, the vehicle-mounted display device preferably also includes a door cover 4, two guide brackets 22 fixedly connected to each side bracket 21 and spaced apart in the translational direction of the display screen 1, and two symmetrically arranged door cover guide rod assemblies 24. In this embodiment, especially as Figure 11B , Figure 12B and Figure 17As shown, the door cover 4 includes a body 41, two connecting arms 42 extending from both sides of the body 41, and a gear 43 disposed at the end of each connecting arm 42. The door cover 4 is hinged to each side bracket 21 of the housing via a pivot 44 extending from each gear 43. Each door cover guide rod assembly 24 includes a door cover guide rod, which is movably disposed on two guide brackets 22 of the corresponding side bracket 21 along the translation direction of the display screen 1, and is provided with a rack 2411 extending along the translation direction of the display screen 1 and meshing with the corresponding gear 43. Thus, the movement of the door cover guide rod along the translation direction of the display screen 1 can drive the gear 43 to rotate, thereby causing the body 41 of the door cover 4 to move relative to the housing at the obstruction opening H (reference). Figures 3A to 3C The display 1 is flipped between the closed position and the open position of the cavity that exposes the opening H to allow the display 1 to extend out of the housing.

[0054] like Figure 11B , Figure 12B as well as Figures 13A to 13C As shown, in this embodiment, each door cover guide rod assembly 24 includes a first bracket 241, a second bracket 242, a connecting rod 243, a third bracket 244, and a second elastic element 245 (e.g., a spring). The first bracket 241 is provided with a rack 2411 and a first connecting block 2412. The second bracket 242 is provided with a second connecting block 2421, a sleeve 2422, and a stop block 2423. One end of the connecting rod 243 is fixedly connected to the first connecting block 2412 by a first screw 246, and the other end of the connecting rod 243 is fixedly connected to the second connecting block 2421 by a first screw 246. Thus, the first bracket 241 and the second bracket 242 are connected to each other through the connecting rod 243 to form a door cover guide rod that can move along the translation direction of the display screen 1. The third bracket 244 includes a base 2441 and sleeve rods 2442 and mounting portions 2443 extending from both sides of the base 2441, wherein the third bracket 244 is fixedly connected to the housing by a second screw 247 passing through the mounting portion 2443, for example, fixedly connected to the side bracket 21, a sleeve 2422 is movably sleeved on the sleeve rod 2442, and a second elastic member 245 is provided between the door cover guide rod and the housing, more specifically, sleeved on the sleeve 2422 and the sleeve rod 2442 between the stop block 2423 and the base 2441.

[0055] like Figures 14A to 16B As shown, the second transmission arm 3 is equipped with a trigger part, such as a protrusion 305. When the display screen 1 is in such a state... Figure 14A When the display screen 1 is in the extended position or in the extended position, the protrusion 305 of the second transmission arm 3 and the stop 2423 of the door cover guide rod are spaced apart in the translational direction of the display screen 1. During the translational movement of the display screen 1 from the extended position to the retracted position, when the display screen 1 reaches the position shown... Figure 14BWhen the display screen 1 is in the middle position as shown, the protrusion 305 begins to contact the stop 2423, and then moves from that middle position to the position shown. Figure 14C During the process of retracting the door cover into the storage position, the door cover guide rod is moved synchronously along the translation direction by pushing the stop 2423, so that the second elastic member 245 is compressed and stored between the stop 2423 and the base 2441, and the movement of the rack 2411 drives the gear 43 to rotate, thereby causing the body 41 of the door cover 4 to flip to the closed position to block the opening H of the housing.

[0056] As the display screen 1 moves from the storage position toward the extension position, the thrust exerted by the protrusion 305 on the stop 2423 is released, allowing the second elastic member 245 to push the door cover guide rod to move along the translation direction of the display screen 1 by releasing elastic potential energy. The movement of the rack 2411 can drive the gear 43 to rotate, thereby causing the body 41 of the door cover 4 to flip toward the open position to expose the opening H of the housing, so that the display screen 1 can extend out of the cavity of the housing through the opening H.

[0057] Therefore, in this vehicle display device, when the display screen 1 moves, the door cover 4 can be made to follow the movement through the door cover guide rod assembly 24, without the need to set an additional drive mechanism for the door cover 4, thus simplifying the overall structure and reducing costs.
