[0041] This embodiment provides a display screen base structure that allows for the detachable installation of the display screen, facilitating its fixation or removal and thus improving the passenger experience.

[0042] Please see Figures 1-8 A display screen base structure includes a housing, a claw assembly, an ejector assembly, and a drive assembly. The claw assembly, ejector assembly, and drive assembly are all installed in the housing. The display screen 10 is clipped onto the upper surface of the housing. The drive assembly is used to drive the claw assembly to lock or unlock the display screen 10, and also to drive the ejector assembly to eject or retract the display screen 10.

[0043] Specifically, please refer to Figure 1 The housing consists of an upper shell 11 and a lower shell 12 that fit together. The upper shell 11 and the lower shell 12 cooperate to form an installation space. The upper shell 11 and the lower shell 12 are provided with multiple sets of corresponding screw holes around their circumference. After the claw assembly, the ejection assembly and the drive assembly are assembled into the installation space, multiple screws are used to pass through the multiple screw holes of the upper shell 11 one by one and screw them into the corresponding screw holes of the lower shell 12 to complete the assembly of the display screen base structure.

[0044] In this embodiment, a mounting groove is provided on the upper surface of the housing. For example, the mounting groove is formed on the surface of the upper housing 11. The display is secured in the mounting groove to prevent the edges of the display from being bumped or knocked during use.

[0045] Preferably, a silicone sleeve is provided inside the mounting groove, and the silicone sleeve is sandwiched between the display screen 10 and the mounting groove. With the above arrangement, when subjected to external impact, the silicone sleeve provides cushioning for the display screen 10 and prevents the display screen 10 from bumping against the mounting groove.

[0046] Specifically, please refer to Figures 2-4 The claw assembly includes a claw 21, which slides along a first direction and is confined within the housing, i.e., within the installation space. The first direction is the width direction of the display screen 10. One end of the claw 21 extends out of the housing. Correspondingly, a slot is provided on the first sidewall 101 of the display screen 10, which is one side along the length direction of the display screen 10. Through the above configuration, the claw 21 can slide along the first direction to engage or disengage from the slot, thereby achieving the fixing and disassembly of the display screen 10.

[0047] Optionally, the silicone sleeve and the groove wall of the mounting groove are respectively provided with a first groove and a second groove for the claw 21. During the sliding of the claw 21 along the first direction, it passes through the second groove and the first groove in sequence and is finally locked in the groove of the display screen 10.

[0048] This embodiment provides a structure in which the claw 21 slides and limits its position within the installation space. For example, please refer to... Figure 2 and Figure 3 The claw assembly also includes a connector 22. One end of the claw 21 extending into the installation space is connected to the connector 22. The connector 22 is slidably mounted on the inner wall of the upper shell 11 along a first direction. With the above configuration, the drive assembly drives the connector 22 to slide along the first direction, thereby enabling the claw 21 to engage or disengage from the slot of the display screen 10.

[0049] Preferably, please refer to Figure 3 The top of the connector 22 is provided with a first groove 2221 along the first direction. Please refer to [link / reference]. Figure 4 The housing is provided with a first guide member 111 fixed inside along the first direction. In this embodiment, the first guide member 111 is fixed to the inner wall of the upper housing 11 and is slidably engaged in the first sliding groove 2221. Through the above arrangement, the reliability of the claw 21 sliding along the first direction is improved and its deviation is prevented.

[0050] The cross-sectional shape of the first slide groove 2221 is arc-shaped, T-shaped or rectangular. In this embodiment, the cross-section of the first slide groove 2221 is arc-shaped.

[0051] To further improve the reliability of the sliding of the chuck 21, please refer to [link / reference needed]. Figure 5 In this embodiment, a guide rod 112 is inserted inside the claw 21. The guide rod 112 is arranged along the first direction, and both ends of the guide rod 112 are fixed inside the housing. For example, a through groove is formed inside the claw 21 along the first direction, and the guide rod 112 is inserted into the through groove with both ends fixed to the inner wall of the upper housing 11. Through the above arrangement, the guide rod 112 further restricts the sliding direction of the claw 21, ensuring that the claw 21 always slides along the guide rod 112, that is, ensuring that the claw 21 slides along the first direction.

[0052] In other feasible embodiments, multiple guide rods 112 are inserted at intervals inside each claw 21, and each guide rod 112 is arranged along a first direction to further improve the reliability of the sliding of the claw 21.

[0053] Optionally, the gap between the guide rod 112 and the through groove inside the claw 21 is set to 0.05mm, which ensures the assembly strength of the guide rod 112 and the claw 21, and also ensures that the claw 21 slides smoothly.

[0054] Preferably, the claw assembly may further include two claws 21. Accordingly, two slots are correspondingly provided on the first sidewall 101 of the display screen 10. The two claws 21 slide along the first direction and can be respectively locked in the two slots to improve the fixing effect on the display screen 10.

[0055] When the jaw assembly includes two jaws 21, both jaws 21 are connected to the connector 22. For example, please refer to... Figure 3 The connector 22 includes an n-shaped rod 221 and a sliding rod 222. One end of the sliding rod 222 is connected to the middle region of the n-shaped rod 221. Two claws 21 are respectively disposed at the two ends of the n-shaped rod 221, and the claws 21 are disposed away from the sliding rod 222. A first groove 2221 is disposed at the top of the sliding rod 222. Preferably, the distance between the two claws 21 and the same end of the sliding rod 222 is equal to ensure that the two claws 21 can simultaneously engage or disengage from their corresponding grooves.

[0056] The drive assembly is configured to drive the claw 21 to slide along a first direction. Specifically, the drive assembly includes a drive member 41 and a first drive unit, the drive member 41 being used to drive the first drive unit to drive the claw 21 to slide along the first direction.

[0057] For example, please refer to Figure 5 and Figure 6 The first drive unit includes a first gear 42, a rack 43, a second gear 44, and a third gear 45. The output end of the drive unit 41 is driven to connect to the first gear 42 to drive the first gear 42 to rotate. The top surface of the rack 43 is provided with a first tooth segment 431, and the first gear 42 meshes with the first tooth segment 431. The bottom surface of the rack 43 is provided with a second tooth segment 432, and the second gear 44 meshes with the second tooth segment 432. Furthermore, the second gear 44 and the third gear 45 are coaxially mounted, and the bottom surface of the other end of the pawl 21 is provided with a fourth tooth segment 211, and the third gear 45 meshes with the fourth tooth segment 211.

[0058] Preferably, the first tooth segment 431, the second tooth segment 432 and the fourth tooth segment 211 are all arranged along the first direction.

[0059] Through the above settings:

[0060] The driving component 41 drives the first gear 42 to rotate clockwise. Since the first gear 42 meshes with the first tooth segment 431 on the top surface of the rack 43, it drives the rack 43 to slide in the direction of extending out of the installation space. Furthermore, since the second gear 44 and the third gear 45 are coaxially mounted, and the second gear 44 meshes with the second tooth segment 432 on the bottom surface of the rack 43, during the process of the rack 43 sliding in the direction of extending out of the installation space, it drives the second gear 44 and the third gear 45 to rotate counterclockwise. Since the third gear 45 meshes with the fourth tooth segment 211, it further drives the pawl 21 to slide to disengage from the slot.

[0061] The driving component 41 drives the first gear 42 to rotate counterclockwise. Since the first gear 42 meshes with the first tooth segment 431 on the top surface of the rack 43, it drives the rack 43 to slide in the direction of extending into the installation space. Furthermore, since the second gear 44 and the third gear 45 are coaxially mounted, and the second gear 44 meshes with the second tooth segment 432 on the bottom surface of the rack 43, during the process of the rack 43 sliding in the direction of extending into the installation space, it drives the second gear 44 and the third gear 45 to rotate clockwise. Since the third gear 45 meshes with the fourth tooth segment 211, it further drives the pawl 21 to slide to lock in the slot.

[0062] It should be noted that the length of the second tooth segment 432 provided on the bottom surface of the rack 43 is preset. When the second gear 44 rotates from one end of the second tooth segment 432 to the other end of the second tooth segment 432, the pawl 21 can be fully engaged or disengaged from the slot.

[0063] Optionally, the drive component 41 is fixed to the inner wall of the upper shell 11, and the drive assembly also includes a mounting bracket 40. The mounting bracket 40 is disposed on the inner wall of the upper shell 11 and has multiple mounting positions. The second gear 44 is rotatably mounted on one of the mounting positions.

[0064] Further optional, please refer to Figure 4 and Figure 6 A second guide member 401 and a third guide member 402 are fixedly fixed on the mounting bracket 40 at intervals along the first direction. A second slide groove 433 and a third slide groove 434 are provided at intervals on the top surface of the rack 43. The first tooth segment 431 is located between the second slide groove 433 and the third slide groove 434. The second guide member 401 is slidably disposed in the second slide groove 433, and the third guide member 402 is slidably disposed in the third slide groove 434. During the sliding process of the rack 43, the second guide member 401 and the third guide member 402 play a guiding role for the rack 43 to avoid the rack 43 from deviating.

[0065] The cross-sectional shape of the second slide groove 433 and the third slide groove 434 is arc-shaped, T-shaped or rectangular. In this embodiment, the cross-section of the second slide groove 433 and the third slide groove 434 is T-shaped, which has the function of improving the assembly strength with the second guide member 401 and the third guide member 402.

[0066] Preferably, the gap between the second guide 401 and the second slide groove 433 is 0.05mm, and the gap between the third guide 402 and the third slide groove 434 is also set to 0.05mm, which can ensure that the second guide 401 does not disengage and that the rack 43 can slide smoothly.

[0067] Please see Figure 2 The ejection assembly includes an ejection block 31, which is arc-shaped and rotates to eject or retract the display screen 10 into the mounting slot. In this embodiment, the rotation of the ejection block 31 is confined to the inside of the housing, i.e., the mounting space, and the ejection block 31 is located close to the first side wall 101. The rotation trajectory of the ejection block 31 smoothly connects with the arc it forms.

[0068] Accordingly, a through slot is provided at the bottom of the mounting slot, and the top of the ejector block 31 can pass through the through slot to extend out of the housing and attach to the bottom surface of the display screen 10.

[0069] Further, please refer to Figure 2 and Figure 4 An internal limiting member 113 is fixedly provided in the housing. The limiting member 113 provides support for the ejector block 31 and guides its sliding. For example, the limiting member 113 includes a fixed portion 1131 and an arc-shaped portion 1132. One end of the fixed portion 1131 is fixed inside the housing, specifically to the inner wall of the upper shell 11. One end of the arc-shaped portion 1132 is connected to the other end of the fixed portion 1131, and the other end of the arc-shaped portion 1132 extends away from the fixed portion 1131. (See [reference needed]). Figure 7 Furthermore, the side wall of the ejector block 31 is provided with an arc-shaped groove 311, which extends to the bottom of the ejector block 31. The arc-shaped part 1132 is slidably engaged in the arc-shaped groove 311, and the ejector block 31 is always confined in the arc-shaped groove 311 during the sliding process.

[0070] Preferably, in this embodiment, two limiting members 113 are provided at intervals inside the shell. The arc-shaped portions 1132 of the two limiting members 113 are respectively slidably engaged in the arc-shaped grooves 311 on opposite sides of the ejector block 31, further improving the support and guiding effect on the ejector block 31.

[0071] Optionally, a magnetic element 32 is embedded in the top of the ejector block 31, so that the top of the ejector block 31 can be attached to the bottom surface of the display screen 10 to prevent the display screen 10 from falling. Further optionally, a silicone pad 33 is laid on the top of the ejector block 31 to cushion the hard contact between the ejector block 31 and the display screen 10.

[0072] The drive assembly also includes a second drive unit configured to drive the ejector block 31 to rotate, thereby ejecting the display screen 10 out of the mounting slot, or retracting the display screen 10 into the mounting slot.

[0073] Specifically, please refer to Figure 2 and Figure 8 The second drive unit includes a fourth gear 46, a fifth gear 47, and a sixth gear 48 rotatably mounted inside the housing. The fifth gear 47 and the sixth gear 48 are coaxially mounted. Furthermore, the bottom surface of the rack 43 is provided with a third tooth segment 435 spaced apart from the second tooth segment 432. The third tooth segment 435 is closer to the first sidewall 101 than the second tooth segment 432. The fourth gear 46 meshes with the third tooth segment 435, and the fifth gear 47 meshes with the fourth gear 46. Furthermore, the ejector block 31 is arc-shaped, and the side of the ejector block 31 facing away from the first sidewall 101 is an arc-shaped surface. The fifth tooth segment 312 is provided on the arc-shaped surface, and the sixth gear 48 meshes with the fifth tooth segment 312.

[0074] For example, the third tooth segment 435 is arranged along the first direction, and the fourth gear 46 and the fifth gear 47 are rotatably mounted on other mounting positions on the mounting bracket 40.

[0075] Through the above settings:

[0076] When the second gear 44 rotates from one end of the second tooth segment 432 to the other end of the second tooth segment 432, the pawl 21 completely disengages from the slot. At this time, the fourth gear 46 engages with one end of the third tooth segment 435. The drive unit 41 continues to drive the first gear 42 to rotate clockwise, and then continues to drive the rack 43 to slide in the direction of extending out of the installation space. Since the fourth gear 46 is engaged with the third tooth segment 435 at this time, it drives the fourth gear 46 to rotate counterclockwise. Furthermore, since the fifth gear 47 is engaged with the fourth gear 46, it will drive the fifth gear 47 to rotate clockwise, thereby driving the sixth gear 48, which is coaxially mounted with the fifth gear 47, to rotate clockwise synchronously. Since the sixth gear 48 is engaged with the fifth tooth segment 312 of the ejector block 31, the ejector block 31 gradually ejects the display screen 10 during the clockwise rotation of the sixth gear 48.

[0077] When the display screen 10 needs to be reinstalled into the mounting slot, the drive unit 41 drives the first gear 42 to rotate counterclockwise, causing the rack 43 to slide along the direction of extending into the mounting space, which in turn drives the fourth gear 46 to rotate clockwise, and further drives the fifth gear 47 and the sixth gear 48 to rotate counterclockwise. During the counterclockwise rotation of the sixth gear 48, the ejector block 31 gradually retracts the display screen 10 into the mounting slot.

[0078] In this embodiment, multiple magnetic suction elements 32 are fixed at intervals on the side of the housing away from the top-out block 31. The magnetic suction elements 32 are used to hold the display screen 10 tightly, thereby preventing the display screen 10 from falling off.
