Description

Technical Field

[0001] This application relates to the field of vehicle screen technology, and in particular to a screen flipping mechanism and a vehicle. Background Technology

[0002] In vehicle interior design, screens located in the secondary dashboard area (especially in the rear seats) have become an important feature for enhancing the driving and riding experience. To ensure comfortable use, the screen needs to be tilted upwards at a specific angle. Most secondary dashboard screens in related technologies use a fixed mounting structure, maintaining a preset angle on the dashboard. This causes the screen to protrude from the dashboard, resulting in a significant amount of interior space occupied by the screen. Furthermore, the protruding screen affects the appearance of the secondary dashboard, thus impacting the overall simplicity and refinement of the vehicle interior. Utility Model Content

[0003] In view of this, this application aims to propose a screen flipping mechanism to reduce the screen's occupation of the vehicle's interior space and improve the space utilization rate of the vehicle.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A screen flipping mechanism includes a base, a mounting seat and a driving part disposed on the base, and a transmission assembly disposed between the mounting seat and the driving part; The transmission assembly includes a driving member disposed on the drive shaft of the drive unit, a driven member disposed on the mounting base, and a traction member connecting the driving member and the driven member together. When the driving unit drives the active member to rotate, the traction member can slide relative to the active member and the driven member respectively, and drive the mounting base to flip along a preset flipping trajectory.

[0005] Furthermore, the active component has a first portion coaxially disposed with the drive shaft, and a second portion eccentrically disposed on one side of the first portion; The traction member is located between the second part and the driven member.

[0006] Furthermore, the first part includes a transmission wheel disposed on the drive shaft, the second part includes a transmission rod disposed on the transmission wheel, and the driven member includes a connecting shaft disposed on the mounting base, the connecting shaft being arranged perpendicularly to the transmission rod; The traction component includes a first cylinder that is slidably sleeved on the transmission rod, and a second cylinder that is slidably sleeved on the connecting shaft.

[0007] Furthermore, a limiting part is provided between the base and the mounting base, the limiting part being used to limit the displacement of the mounting base along the axial direction of the connecting shaft.

[0008] Furthermore, the limiting part includes a limiting groove provided on the base and a limiting block provided on the mounting base; The limiting groove is set along the preset flipping trajectory, and the limiting block is inserted into the limiting groove and abuts against the two side walls of the limiting groove.

[0009] Furthermore, the limiting block is provided with an elastic sheet, the elastic sheet having an elastic protrusion that protrudes away from the limiting block; The elastic protrusion presses against the bottom wall of the limiting groove and is used to apply damping force to the movement of the mounting seat.

[0010] Furthermore, the base is provided with a guide groove, and the mounting seat is provided with a guide post inserted into the guide groove; In the vertical direction of the vehicle, the guide groove is a downward-protruding arc-shaped groove, which defines the preset flipping trajectory.

[0011] Furthermore, the base is provided with a detection unit, which is used to detect the position of the mounting base.

[0012] Furthermore, the base is provided with a sliding groove spaced apart from the guide groove, and the mounting seat is provided with a slider, which is slidably disposed in the sliding groove and can guide the mounting seat to rotate; The detection unit includes a first switch and a second switch spaced apart between the guide groove and the slide groove along the length direction of the guide groove. The guide post can trigger the first switch, and the slider can trigger the second switch.

[0013] Compared with related technologies, this application has the following advantages: (1) The screen flipping mechanism described in this application sets a mounting seat for installing the screen on the base and drives the active component to rotate by the driving part on the base. The driven component on the mounting seat can be moved by the traction component, and the mounting seat can be flipped along the preset flipping trajectory, thereby realizing the screen flipping. This not only improves the comfort of passengers, but also enables the screen to be stored by flipping the screen, solving the problem of traditional fixed screens occupying too much space in the vehicle. This improves the space utilization rate in the vehicle and enhances the overall user experience.

[0014] (2) By setting a first part coaxial with the drive shaft and an eccentric second part, when the first part is driven to rotate, the second part can convert the rotational motion of the first part into linear motion in two directions. By setting the traction member between the second part and the driven member, the second part can drive the driven member to move through the traction member, which can ensure that the power transmission of the drive part is smoothly transmitted to the mounting base, so as to ensure that the mounting base flips along the preset trajectory.

[0015] (3) By setting the first part and the second part as a transmission wheel and a transmission rod respectively, the structure is simple and reliable, and can ensure the smooth transmission of power. In addition, the first cylinder can adapt to the rotation of the transmission rod and ensure the stable transmission of power to the connecting shaft. At the same time, by cooperating with the connecting shaft and the second cylinder, the second cylinder can slide along the axial direction of the connecting shaft, thereby ensuring the stable connection between the connecting shaft and the transmission rod when the transmission rod moves in the second direction. Furthermore, the second cylinder can rotate around the connecting shaft to adapt to the angle change of the mounting base when the screen is flipped, prevent transmission jamming, and ensure the smoothness of the screen flipping action.

[0016] (4) By setting the limiting part, the displacement of the mounting base along the connecting shaft can be effectively limited, avoiding left and right offset during screen flipping, and ensuring the stability of screen installation and the accuracy of the flipping trajectory.

[0017] (5) Through the cooperation of the limiting groove and the limiting block, the limiting block can abut against the two side walls of the limiting groove to effectively limit the displacement of the mounting seat along the connecting shaft. Moreover, the structure is simple and easy to design and implement. In addition, the limiting groove can constrain the movement trajectory of the limiting block to limit the rotation trajectory of the mounting seat, thereby preventing the mounting seat from shaking or deviating from the preset trajectory during the rotation process, and further ensuring the accuracy of screen rotation.

[0018] (6) By setting up elastic sheets and elastic protrusions, by driving the elastic protrusions to abut against the bottom wall of the limiting groove, a uniform damping force can be applied to the movement of the mounting base, slowing down the flipping speed, while enhancing the stability of the screen flipping process and avoiding impact caused by flipping too fast.

[0019] (7) By combining the guide groove and the guide post, the guide groove can guide the guide post to move along the preset trajectory, thereby limiting the rotation trajectory and rotation stroke of the mounting base by limiting the movement trajectory of the guide post, further improving the stability of the mounting base and screen rotation. Moreover, this structure is simple and easy to process and manufacture.

[0020] (8) By setting a detection unit on the base, the flip position of the mounting base can be detected in real time, and a control signal can be provided for the start and stop of the drive unit. This ensures that when the mounting base is flipped to the preset position, it can be maintained at the preset flip angle by stopping the drive unit, thus ensuring the stability and consistency of the flipping action.

[0021] (9) By setting a first switch and a second switch, and being able to be triggered by the slider and guide post respectively, the dual detection of the mounting base at the flip limit position can be realized, thereby effectively controlling the start and stop of the drive unit, ensuring the stability and consistency of the flipping action, avoiding excessive flipping of the mounting base and structural damage, and improving the reliability of the screen flipping mechanism.

[0022] Another object of this application is to provide a vehicle equipped with a screen flipping mechanism as described above.

[0023] The vehicle described in this application and / or the screen flipping mechanism described above have the same technical effects as related technologies, and will not be described again here. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a screen flipping mechanism.

[0032] In related technologies, screens located on the secondary instrument panel often adopt a fixed installation structure. The screen always maintains a preset angle on the secondary instrument panel, causing the screen to protrude from the instrument panel. This results in the screen area occupying more interior space, and the protruding screen affects the appearance of the secondary instrument panel, thereby affecting the overall simplicity and refinement of the vehicle interior.

[0033] In view of this, in order to overcome the shortcomings of related technologies, the screen flipping mechanism of this embodiment combines... Figure 1 , Figure 9 As shown, the overall design includes a base 1, a mounting base 2 and a drive unit 103 disposed on the base 1, and a transmission assembly disposed between the mounting base 2 and the drive unit 103.

[0034] The transmission assembly includes a driving member 3 mounted on a drive shaft 1031 of the drive unit 103, a driven member mounted on the mounting base 2, and a traction member 5 connecting the driving member 3 and the driven member. When the drive unit 103 drives the driving member 3 to rotate, the traction member 5 can slide relative to the driving member 3 and the driven member respectively, and drive the mounting base 2 to rotate along a preset rotation trajectory.

[0035] Therefore, by setting a mounting seat 2 for installing the screen on the base 1, and using the drive unit 103 on the base 1 to drive the active member 3 to rotate, the driven member on the mounting seat 2 can be moved by the traction member 5, and finally the mounting seat 2 can be flipped along the preset flipping trajectory, thereby realizing the flipping of the screen. This not only improves the comfort of passengers, but also allows the screen to be stored by flipping it, solving the problem of fixed screens occupying too much space in the vehicle, thereby improving the space utilization rate in the vehicle and improving the overall user experience.

[0036] Based on the above overview, specifically, the screen flipping mechanism of this embodiment includes a first state and a second state. In the first state, the screen can flip open along with the mounting base 2 for easy use. In the other state, the screen flips back to its original position along with the mounting base 2, and is in a stored, unused state.

[0037] Combination Figure 4 As shown, the screen flipping mechanism of this embodiment is located in the sub-dashboard of the vehicle, particularly on the sub-dashboard of the rear row. The base 1 of this embodiment is connected to the sub-dashboard, and the base 1 includes a groove structure formed by a bottom plate 101 and a side plate 102. The groove structure is recessed towards the side of the sub-dashboard away from the occupants, and the top of the groove structure is open to facilitate the installation and arrangement of the screen.

[0038] Based on this, the mounting base 2 and the transmission assembly are both located in the recessed structure, thereby preventing the mounting base 2 and the transmission assembly from protruding from the sub-dashboard, reducing the space occupied by the mounting base 2 and the transmission assembly, and avoiding the transmission assembly from being exposed and affecting the refinement of the vehicle interior.

[0039] In addition, combined Figure 1 As shown, the mounting base 2 in this embodiment has multiple mounting holes 201 for mounting the screen, and the mounting base 2 also has positioning protrusions 202 protruding towards the screen. During screen installation, the positioning protrusions 202 can be inserted into the positioning holes on the back of the screen to ensure accurate alignment between the screen and each mounting hole 201. Subsequently, the screen can be mounted on the mounting base 2 using fasteners such as bolts to ensure a stable connection between the mounting base 2 and the screen, and to ensure that the screen can rotate with the mounting base 2.

[0040] In some exemplary embodiments, the driving member 3 has a first portion coaxially arranged with the drive shaft 1031, and a second portion eccentrically disposed to one side of the first portion. The traction member 5 is disposed between the second portion and the driven member. In a specific implementation, the flipping axis of the mounting base 2 in this embodiment is parallel to the second direction.

[0041] Understandably, to drive the mounting base 2 to rotate around the second direction, the driven member needs to move around the rotation axis of the mounting base 2. In this case, viewed from the second direction, during the rotation of the mounting base 2, the driven member will simultaneously move upwards in the first and third directions. Due to the structural constraints of the mounting base 2, the distance between the driven member and the rotation axis remains constant. Therefore, when the driven member is subjected to an upward driving force in the first or third direction, it can move around the rotation axis, thereby completing the rotation action of the mounting base 2.

[0042] Based on this, by setting a first part coaxial with the drive shaft 1031 and an eccentric second part, when the first part is driven to rotate, the second part, due to its eccentric setting, can rotate around the drive shaft 1031 along with the first part. At this time, the second part moves synchronously upward in the second and third directions, thereby enabling the second part to convert the rotational motion of the first part into linear motion in both directions.

[0043] For example, when the drive shaft 1031 is parallel to the first direction, the second part moves in the second direction and the third direction upward as the first part rotates. When the second part moves in the third direction, it can apply a driving force in the third direction to the driven member via the traction member 5, thereby causing the mounting base 2 to flip.

[0044] Therefore, by placing the traction member 5 between the second part and the driven member, the second part can drive the driven member to move through the traction member 5, which can ensure that the power transmission of the drive unit 103 is smoothly transmitted to the mounting base 2, so as to ensure that the mounting base 2 rotates along the preset trajectory.

[0045] It is worth mentioning that in this embodiment, the axial direction of the drive shaft 1031 is parallel to the first direction, and the first part rotates around the first direction. Accordingly, in this embodiment, the drive shaft 1031 is rotatably mounted on a side plate 102 of the base 1 perpendicular to the first direction, and the drive part 103 is provided on the side of the side plate 102 away from the mounting base 2, so as to prevent the drive part 103 from occupying the space inside the base 1 and to avoid interference between the drive part 103 and the transmission assembly and the mounting base 2.

[0046] Meanwhile, the first, second, and third directions of this embodiment can be set to the front-rear, left-right, and up-down directions of the vehicle, respectively. In this case, the screen can face the front of the driver and passengers for easy use. Of course, the three directions of this embodiment can also be adjusted to other directions according to actual use needs to facilitate screen rotation and use.

[0047] Combination Figure 5 , Figure 10As shown, in some exemplary embodiments, the first part includes a transmission wheel 301 mounted on the drive shaft 1031, the second part includes a transmission rod 302 mounted on the transmission wheel 301, and the driven member includes a connecting shaft 4 mounted on the mounting base 2, the connecting shaft 4 being arranged perpendicularly to the transmission rod 302. Figure 15 As shown, the traction component 5 includes a first cylinder 501 slidably sleeved on the transmission rod 302 and a second cylinder 502 slidably sleeved on the connecting shaft 4.

[0048] By setting the first part and the second part as a transmission wheel 301 and a transmission rod 302 respectively, the structure is simple and reliable, ensuring smooth power transmission. Furthermore, combined with... Figure 6 , Figure 11 As shown, by setting the first cylinder 501, relative rotation occurs between the first cylinder 501 and the transmission rod 302, thus avoiding transmission interference.

[0049] It is understandable that when the transmission rod 302 moves synchronously upwards in the second and third directions with the rotation of the transmission wheel 301, the transmission rod 302 can apply a driving force to the connecting shaft 4 in the third direction through the traction member 5, thereby driving the mounting base 2 to rotate. As the mounting base 2 rotates, the connecting shaft 4 will not only move along the third direction with the transmission rod 302, but will also move in the first direction. Therefore, combined with... Figure 7 , Figure 12 As shown, by setting the first cylinder 501, the first cylinder 501 can move along the transmission rod 302 in the first direction to eliminate the transmission interference between the connecting shaft 4 and the transmission rod 302 in the first direction, and ensure the stable transmission of power to the connecting shaft 4.

[0050] Meanwhile, by cooperating with the connecting shaft 4 and the second cylinder 502, the second cylinder 502 can slide along the axial direction of the connecting shaft 4, thereby ensuring a stable connection between the connecting shaft 4 and the transmission rod 302 when the transmission rod 302 moves in the second direction, and eliminating motion interference between the connecting shaft 4 and the transmission rod 302 in the second direction.

[0051] Furthermore, the second cylinder 502 can rotate around the connecting shaft 4 to adapt to the angle change of the mounting base 2 when the screen is flipped, avoid transmission jamming between the traction component 5 and the mounting base 2, and ensure the smoothness of the screen flipping action.

[0052] In specific implementation, the drive unit 103 of this embodiment can be a drive motor, and the output shaft of the drive motor can be connected to the drive shaft 1031 through a gear transmission structure to drive the drive shaft 1031 and the transmission wheel 301 to rotate. Alternatively, the output shaft of the drive motor can be directly coaxially connected to the drive shaft 1031 to directly drive the transmission wheel 301 to rotate. Of course, the drive unit 103 of this embodiment can also use other conventional drive mechanisms that can drive the drive shaft 1031 to rotate, ultimately achieving the flipping of the mounting base 2.

[0053] Of course, the driving component in this embodiment can also adopt other structural forms, such as an eccentric shaft. When the driving component is an eccentric shaft, the first part of this embodiment is a first shaft body, and the second part is a second shaft body arranged eccentrically with respect to the first shaft body. The second shaft body can be directly disposed on one side of the first shaft body, or a connecting part for connecting the second shaft body can be formed on the first shaft body. In this case, the first shaft body is coaxially connected to the drive shaft 1031, or the eccentric shaft is integrally formed with the drive shaft 1031, which can drive the rotation of the mounting base 2.

[0054] Combination Figure 3 , Figure 4 As shown, in some exemplary embodiments, a limiting part is provided between the base 1 and the mounting base 2 to limit the axial displacement of the mounting base 2 along the connecting shaft 4. By providing the limiting part, the axial displacement of the mounting base 2 along the connecting shaft 4 can be effectively limited, preventing left and right offset during screen flipping and ensuring the stability of screen installation and the accuracy of the flipping trajectory.

[0055] Specifically, the limiting part in this embodiment includes a limiting groove 1011 provided on the base 1 and a limiting block 203 provided on the mounting base 2. The limiting groove 1011 is set along a preset flipping trajectory, and the limiting block 203 is inserted into the limiting groove 1011 and abuts against the two side walls of the limiting groove 1011.

[0056] By cooperating with the limiting groove 1011 and the limiting block 203, the limiting block 203 can abut against the two side walls of the limiting groove 1011 to effectively limit the displacement of the mounting base 2 along the connecting shaft 4. Moreover, the structure is simple and easy to manufacture. Furthermore, the limiting groove 1011 can constrain the movement trajectory of the limiting block 203 to limit the flipping trajectory of the mounting base 2, thereby preventing the mounting base 2 from shaking or deviating from the preset trajectory during the flipping process, further ensuring the accuracy of screen flipping. In specific implementation, the limiting groove 1011 of this embodiment is provided on the bottom plate 101 of the base 1 and extends along the first direction.

[0057] Furthermore, in combination Figure 3 , Figure 14As shown, in some exemplary embodiments, the limiting block 203 is provided with an elastic sheet 2031, the elastic sheet 2031 having an elastic protrusion 2032 protruding in a direction away from the limiting block 203. The elastic protrusion 2032 presses against the bottom wall of the limiting groove 1011 and is used to apply a damping force to the movement of the mounting base 2.

[0058] By setting the elastic sheet 2031 and the elastic protrusion 2032, by driving the elastic protrusion 2032 to abut against the bottom wall of the limiting groove 1011, a uniform damping force can be applied to the movement of the mounting base 2, slowing down the flipping speed, while enhancing the stability of the screen flipping process and avoiding impact caused by flipping too fast.

[0059] In specific implementation, the first limiting groove 1011 is an arc-shaped groove, and the elastic protrusions 2032 are configured as two separate locations at both ends of the elastic sheet 2031 in the first direction. This ensures that during the rotation of the mounting base 2, the elastic protrusions 2032 on the elastic sheet 2031 remain in contact with the bottom of the limiting groove 1011, thus ensuring a damping effect during the rotation of the mounting base 2. Simultaneously, the elastic sheet 2031 is bolted to the bottom of the limiting block 203, and the bolt is bolted between the two elastic protrusions 2032.

[0060] In addition, to improve the installation efficiency of the elastic sheet 2031 on the limiting block 203, positioning grooves are provided on both sides of the elastic sheet 2031. Corresponding to the positioning grooves, the limiting block 203 is provided with downward protruding positioning protrusions, and the positioning protrusions on each side are respectively inserted into the positioning grooves on the corresponding sides, so that the elastic protrusion 2032 can also be quickly positioned on the limiting block 203.

[0061] In some of the exemplary implementations, combined with Figure 4 , Figure 8 and Figure 13 As shown, the base 1 is provided with a guide groove 1021, and the mounting base 2 is provided with a guide post 204 inserted into the guide groove 1021. In the vertical direction of the whole vehicle, the guide groove 1021 is a downwardly protruding arc-shaped groove, which defines a preset flipping trajectory.

[0062] By cooperating with the guide groove 1021 and the guide post 204, the guide groove 1021 can guide the guide post 204 to move along a preset trajectory, thereby limiting the flipping trajectory and flipping stroke of the mounting base 2 by limiting the movement trajectory of the guide post, and further improving the flipping stability of the mounting base 2 and the screen.

[0063] In specific implementation, the guide groove 1021 of this embodiment extends along an arc-shaped trajectory. The center of the arc-shaped trajectory of the guide groove 1021 coincides with the flip axis of the mounting base 2 to ensure that the mounting base 2 rotates stably around the flip axis.

[0064] In addition, both ends of the mounting base 2 in this embodiment are provided with guide posts 204, and the base 1 is provided with two guide grooves 1021 corresponding to the two guide posts 204, so as to further ensure the stability of the mounting base 2 when flipping. At the same time, a connecting rod 206 is provided between the two guide posts 204 to ensure the connection stability between the mounting base 2 and the two guide posts 204.

[0065] In some of the exemplary implementations, combined with Figure 9 As shown, a detection unit 6 is provided on the base 1, which detects the position of the mounting base 2. By providing the detection unit 6 on the base 1, the flip position of the mounting base 2 can be detected in real time, providing a control signal for the start and stop of the drive unit 103. This ensures that when the mounting base 2 is flipped to the preset position, it can be maintained at the preset flip angle by stopping the drive unit 103, thus ensuring the stability and consistency of the flipping action.

[0066] Among them, combined Figure 8 , Figure 9 and Figure 13 As shown, in one specific embodiment, the base 1 is provided with a sliding groove 1022 spaced apart from the guide groove 1021, and the mounting base 2 is provided with a slider 205. The slider 205 is slidably disposed in the sliding groove 1022 and can guide the mounting base 2 to rotate. The detection unit 6 includes a first switch 601 and a second switch 602 spaced apart between the guide groove 1021 and the sliding groove 1022 along the length direction of the guide groove 1021. The guide post 204 can trigger the first switch 601, and the slider 205 can trigger the second switch 602.

[0067] By setting the first switch 601 and the second switch 602, which can be triggered by the slider 205 and the guide post 204 respectively, dual detection of the mounting base 2 at the extreme position of the flip can be achieved. This effectively controls the start and stop of the drive unit 103, ensuring the stability and consistency of the flipping action, avoiding structural damage caused by excessive flipping of the mounting base 2, and improving the reliability of the screen flipping mechanism. At the same time, the cooperation between the slide groove 1022 and the slider 205 can also provide support and guidance for the mounting base 2, ensuring that the mounting base 2 flips along the preset trajectory, further improving the stability of the flipping of the mounting base 2.

[0068] In specific implementation, the sliders 205 in this embodiment are also configured as two at both ends of the mounting base 2, and the base 1 is provided with grooves 1022 corresponding to the two sliders 205 one by one. At the same time, the grooves 1022 are also arc-shaped grooves, and the center of the arc trajectory of the groove 1022 coincides with the center of the arc trajectory of the guide groove 1021, so as to ensure that the grooves 1022 and the guide grooves 1021 can jointly guide the mounting base 2 to rotate along the same flip axis, further ensuring the stability of the mounting base 2 and the screen flipping.

[0069] In addition, combined Figure 8 , Figure 13 As shown, in this embodiment, both the first switch 601 and the second switch 602 are microswitches, with their trigger ends facing the guide groove 1021 and the slide groove 1022, respectively. The first switch 601 is located at the end of the guide groove 1021 near the drive unit 103. When the screen flipping mechanism is in the first state, the guide post 204 can abut against the trigger end of the first switch 601 to trigger it. The second switch 602 is located at the end of the slide groove 1022 away from the drive unit 103. When the screen flipping mechanism is in the second state, the slider 205 can abut against the trigger end of the second switch 602 to trigger it. Therefore, when the first switch 601 and the second switch 602 are triggered, they can send a switch signal, and the control unit of the drive unit 103 can rotate a preset angle to start or stop based on this switch signal.

[0070] Furthermore, in combination Figure 16 As shown, in this embodiment, a circuit board 603 for mounting the first switch 601 and the second switch 602 is provided between the guide groove 1021 and the slide groove 1022. The circuit board 603 is connected to the drive unit 103 via a wiring harness 604, so that the first switch 601 and the second switch 602 can control the start and stop of the drive unit 103. Of course, the first switch 601 and the second switch 602 in this embodiment can also be other conventional switches known to those skilled in the art, such as Hall switches, photoelectric switches, etc., which can be triggered by the corresponding slider 205 or guide post 204 when the mounting base 2 is flipped to the preset position.

[0071] Furthermore, viewed from the second direction, both the guide post 204 and the slider 205 in this embodiment are elongated oval to ensure smooth sliding within the slide groove 1022 and guide groove 1021. Simultaneously, corresponding to the slide groove 1022 and guide groove 1021, the base 1 in this embodiment is provided with a protective cover plate 7. The protective cover plate 7 can shield the slide groove 1022 and guide groove 1021 to prevent external impurities from entering and affecting the smooth sliding of the slider 205 and guide post 204, thereby ensuring the smooth rotation of the mounting base 2.

[0072] Specifically, combined Figure 8 , Figure 13 and Figure 16As shown, in this embodiment, the circuit board 603, which carries the first switch 601 and the second switch 602, is located on the outside of the protective cover 7 to facilitate the maintenance and replacement of the first switch 601, the second switch 602, and the circuit board 603. Meanwhile, the protective cover 7 has two hollowed-out portions 701 corresponding to the slide groove 1022 and the guide groove 1021, respectively. The guide post 204 has a first trigger piece 2041 for abutting the trigger end of the first switch 601, and the slider 205 has a second trigger piece 2051 for abutting the trigger end of the second switch 602. The first trigger piece 2041 and the second trigger piece 2051 can pass through the corresponding hollowed-out areas to trigger the first switch 601 and the second switch 602, thereby ensuring the reliability of the detection unit 6 while utilizing the protective cover 7 for protection.

[0073] It is worth noting that, regarding the screen flipping mechanism of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 16 As shown, it may include, for example, a base 1, a mounting base 2 and a drive unit 103 disposed on the base 1, and a transmission assembly disposed between the mounting base 2 and the drive unit 103.

[0074] The transmission assembly includes a driving member 3 mounted on a drive shaft 1031 of the drive unit 103, a driven member mounted on the mounting base 2, and a traction member 5 connecting the driving member 3 and the driven member. When the drive unit 103 drives the driving member 3 to rotate, the traction member 5 can slide relative to the driving member 3 and the driven member respectively, and drive the mounting base 2 to rotate along a preset rotation trajectory.

[0075] Specifically, the driving member 3 protects the transmission wheel 301 mounted on the drive shaft 1031 and the transmission rod 302 mounted on the transmission wheel 301. The driven member includes a connecting shaft 4 mounted on the mounting base 2, which is arranged perpendicularly to the transmission rod 302. The traction member 5 includes a first cylinder 501 slidably sleeved on the transmission rod 302 and a second cylinder 502 slidably sleeved on the connecting shaft 4.

[0076] Furthermore, a limiting part is provided between the base 1 and the mounting base 2. The limiting part includes a limiting groove 1011 on the base 1 and a limiting block 203 on the mounting base 2. The limiting groove 1011 is set along a preset flipping trajectory, and the limiting block 203 is inserted into the limiting groove 1011 and abuts against the two side walls of the limiting groove 1011. The limiting block 203 is provided with an elastic piece 2031, which has an elastic protrusion 2032 protruding away from the limiting block 203. The elastic protrusion 2032 presses against the bottom wall of the limiting groove 1011 and is used to apply a damping force to the movement of the mounting base 2.

[0077] Additionally, the base 1 is provided with a guide groove 1021, and the mounting base 2 is provided with a guide post 204 inserted into the guide groove 1021. In the vertical direction of the vehicle, the guide groove 1021 is a downwardly protruding arc-shaped groove, defining a preset flipping trajectory. The base 1 is provided with a sliding groove 1022 spaced apart from the guide groove 1021, and the mounting base 2 is provided with a slider 205, which slides within the sliding groove 1022 and guides the mounting base 2 to flip. The detection unit 6 includes a first switch 601 and a second switch 602 spaced apart between the guide groove 1021 and the sliding groove 1022 along the length of the guide groove 1021. The guide post 204 can trigger the first switch 601, and the slider 205 can trigger the second switch 602.

[0078] In the preferred embodiment of the screen flipping mechanism above, the specific settings and arrangements of the base 1, mounting base 2, transmission components, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the base 1, mounting base 2, and transmission components can also be referred to the descriptions in the above exemplary embodiments.

[0079] In this embodiment, the above design is adopted. By using the driving part 103 on the base 1 to drive the active member 3 to rotate, and by using the traction member 5 to drive the driven member on the mounting seat 2 to move, the mounting seat 2 can be flipped along the preset flipping trajectory, thereby realizing the screen flipping. This reduces the screen's occupation of the vehicle's interior space. At the same time, by flipping the screen, the screen can be stored, improving the space utilization rate inside the vehicle and ultimately enhancing the overall user experience of the vehicle.

[0080] An embodiment of the second aspect of this application provides a vehicle equipped with a screen flipping mechanism as described above.

[0081] In this embodiment, the vehicle, through the aforementioned screen flipping mechanism, utilizes the cooperation between the drive unit 103 and the transmission component to drive the mounting base 2 equipped with the screen to flip, thereby achieving screen flipping. This reduces the screen's occupation of the vehicle's interior space, thereby improving the space utilization and refinement of the interior, as well as the overall user experience of the vehicle.
