[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0032] Please see Figure 1 This application provides a drive mechanism 100, a central control screen device 700 configured with the drive mechanism 100, and a transport vehicle 1000 configured with the central control screen device 700. In this embodiment, the transport vehicle 1000 is a means of transportation for transporting goods or carrying people. In this embodiment, the type of transport vehicle 1000 may include vehicles (cars, trucks, etc.), aircraft (helicopters, passenger planes, etc.), and ships (cargo ships or passenger ships, etc.). In this embodiment, the structure of the transport vehicle 1000 is specifically described using a vehicle as an example. In this embodiment, the transport vehicle 1000 may include a vehicle body 900, which constructs the main structure of the transport vehicle 1000 and defines spaces such as a cockpit, passenger cabin, and cargo hold.

[0033] Please see Figure 1 and Figure 2 In this embodiment, the transport vehicle 1000 also includes a control device 800, which is mounted on the vehicle body 900. The driver operates the control device 800 to change the forward direction and other states of the transport vehicle 1000. In this embodiment, the transport vehicle 1000 can be a vehicle, and the vehicle body 900 has a driver's seat 910 and a passenger seat 920. The control device 800 is located approximately in front of the driver's seat 910, and this front is roughly in the same direction as the forward direction of the transport vehicle 1000. In this embodiment, the control device 800 includes a steering wheel. In other embodiments, the transport vehicle 1000 can be an aircraft, and the control device 800 includes a control stick, rudder pedals, etc.

[0034] In this embodiment, the transport vehicle 1000 also includes a central control screen device 700, which is installed on the vehicle body 900. The central control screen device 700 is used to interact with the driver to assist the driver in operating the transport vehicle 1000. The vehicle body 900 has a central control console 930, which is located between the driver's seat 910 and the passenger seat 920. The central control console 930 is located on one side of the driver's seat 910 and the control device 800. The central control screen device 700 is installed on the central control console 930 so that the driver can view the images or data displayed on the central control screen device 700. The central control console 930 has a generally table-like structure, and the volume control knob, headlight buttons, and other adjustment structures of the transport vehicle 1000 can be integrated into the central control console 930. In this embodiment, the central control screen device 700 includes a display 600, which is mounted on the central control panel 930. The display 600 can be used to display maps, driving data of the transport vehicle 1000 (such as driving speed, driving time, etc.), and the status of the transport vehicle 1000 (such as wheel pressure, parking image, etc.).

[0035] In this embodiment, the central control screen device 700 may further include a drive mechanism 100, which is connected between the central control panel 930 and the display 600. The drive mechanism 100 is used to drive the display 600 to move relative to the central control panel 930 or the driver's seat 910. The drive mechanism 100 includes a base 10, a guide assembly 20, a mounting bracket 30, and a drive assembly 40. The guide assembly 20 is mounted on the base 10, the mounting bracket 30 is used to mount the display 600, and the mounting bracket 30 is slidably mounted on the guide assembly 20 and moves under the guidance of the guide assembly 20. The drive assembly 40 is mounted on the base 10 and is drivenly connected to the mounting bracket 30, driving the mounting bracket 30 to move. In this embodiment, the base 10 is mounted on the central control panel 930.

[0036] Please see Figure 3 and Figure 4 In this embodiment, the guide component 20 includes a first guide segment 21 and a second guide segment 22 that are connected to each other. The extension direction of the first guide segment 21 intersects the extension direction of the second guide segment 22. The first guide segment 21 is defined to extend along a first direction A, and the second guide segment 22 is defined to extend along a second direction B. The first direction A and the second direction B intersect. The mounting bracket 30 is provided with at least one sliding connection portion 33, which can be slidably connected to the first guide segment 21 and also slidably connected to the second guide segment 22.

[0037] In practical applications, the sliding connection 33 is slidably connected to one of the first guide segment 21 and the second guide segment 22. As an example, the sliding connection 33 is slidably connected to the first guide segment 21, and the mounting bracket 30 moves along a first direction A under the guidance of the first guide segment 21; the sliding connection 33 is also slidably connected to the second guide segment 22, and the mounting bracket 30 moves along a second direction B under the guidance of the second guide segment 22. The movement directions of the mounting bracket 30 under the guidance of the first guide segment 21 and the second guide segment 22 are different, and the two movement directions intersect. In this embodiment, the first guide segment 21 and the second guide segment 22 are connected to each other. After the first guide segment 21 finishes guiding the mounting bracket 30, the second guide segment 22 immediately continues to guide the movement of the mounting bracket 30. It is known that the mounting bracket 30 moves in different directions under the guidance of the first guide section 21 and the second guide section 22. Therefore, as the sliding connection part 33 finishes cooperating with the first guide section 21 and begins to cooperate with the second guide section 22, the mounting bracket 30 gradually deflects as a whole, so as to gradually switch from the state of moving along the first direction A to the state of moving along the second direction B.

[0038] In this embodiment, the first guide segment 21 has a relatively long extension length, allowing the mounting bracket 30 to slide a certain distance along the first direction A. The second guide segment 22 has a relatively short extension length, and the sliding connecting part 33 slides a certain distance under the guidance of the second guide segment 22 before reaching the end of the second guide segment 22, at which point the mounting bracket 30 stops rotating. In this embodiment, with the sliding connecting part 33 reaching the end of the second guide segment 22, the driver can more easily observe the content on the display 600. In other embodiments, the extension lengths of the first guide segment 21 and the second guide segment 22 are set according to requirements.

[0039] In summary, in this embodiment, the drive mechanism 100 includes a base 10, a guide component 20, a mounting bracket 30, and a drive component 40. The guide component 20 is mounted on the base 10, and the mounting bracket 30 is used to mount the display 600. The mounting bracket 30 is slidably mounted on the guide component 20 and moves under the guidance of the guide component 20. The drive component 40 is mounted on the base 10 and is driven by the mounting bracket 30, driving the mounting bracket 30 to move. In this embodiment, the guide component 20 includes a first guide segment 21 and a second guide segment 22 that are connected to each other. The extension direction of the first guide segment 21 intersects the extension direction of the second guide segment 22, such that the movement direction of the mounting bracket 30 under the guidance of the first guide segment 21 is different from the movement direction of the mounting bracket 30 under the guidance of the second guide segment 22. The mounting bracket 30 is provided with at least one sliding connection part 33, which can be slidably connected to the first guide section 21 or the second guide section 22, so that the drive mechanism 100 can drive the mounting bracket 30 to move along the extension direction of the first guide section 21 or the second guide section 22. When the mounting bracket 30 transitions from the first guide section 21 to the second guide section 22, the mounting bracket 30 can deflect.

[0040] In this embodiment, the guide component 20 and the mounting bracket 30 can cooperate with each other to automatically drive the mounting bracket 30 and the display 600 to deflect. There is no need to set up an additional drive structure for driving the mounting bracket 30 to rotate. The number of components in the drive mechanism 100 is small, avoiding excessive weight of the drive mechanism 100 and reducing the cost of the drive mechanism 100. The mounting bracket 30 can deflect automatically without generating instructions to control the rotation of the mounting bracket 30, reducing the data calculation work of the background program, omitting the time for responding to control instructions, and improving the driving efficiency of the drive mechanism 100.

[0041] In this embodiment, the mounting bracket 30 has two sliding connection portions 33, which are located on opposite sides of the mounting bracket 30. Each sliding connection portion 33 is slidably connected to one of the first guide segment 21 and the second guide segment 22. As an example, both sliding connection portions 33 of the mounting bracket 30 can be slidably connected to the first guide segment 21, and the two sliding connection portions 33 are arranged along a first direction A. The mounting bracket 30 moves along the first direction A under the guidance of the first guide segment 21. Alternatively, both sliding connection portions 33 of the mounting bracket 30 can be slidably connected to the second guide segment 22, and the mounting bracket 30 moves along a second direction B under the guidance of the second guide segment 22. The movement directions of the mounting bracket 30 under the guidance of the first guide segment 21 and the second guide segment 22 are different, and the two movement directions intersect. With this configuration, the connection between the mounting bracket 30 and the guide assembly 20 is relatively stable, and the movement state of the mounting bracket 30 is relatively stable, which can reduce the degree of shaking of the mounting bracket 30 and the display 600 during movement.

[0042] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the two sliding connection portions 33 are defined as the first sliding portion 331 and the second sliding portion 332. When the mounting bracket 30 is slidably connected to the first guide segment 21, the first sliding portion 331 is located on the side of the mounting bracket 30 closer to the second guide segment 22. The first guide segment 21 and the second guide segment 22 are connected to each other, allowing the mounting bracket 30 to transition from a state slidably connected to the first guide segment 21 to a state where at least a portion of its structure is slidably connected to the second guide segment 22. Please refer to [link to relevant documentation]. Figure 6 During this transition process, the first sliding part 331 is slidably connected to the second guide section 22, and the second sliding part 332 is slidably connected to the first guide section 21. Under the combined guiding action of the first guide section 21 and the second guide section 22, the mounting bracket 30 is in a state of gradual deflection, so that the structure of the mounting bracket 30 gradually separates from the first guide section 21, and the degree of cooperation between the mounting bracket 30 and the second guide section 22 gradually increases. In this embodiment, the mounting bracket 30 can also transition from a state connected to the second guide section 22 to a state connected to the first guide section 21. During this process, the mounting bracket 30 is also in a state of gradual deflection.

[0043] Please see Figure 5 and Figure 6In this embodiment, the mounting bracket 30 is initially positioned and slidably connected to the first guide segment 21. In actual application scenarios, the drive mechanism 100 drives the mounting bracket 30 to move along the first direction A until the mounting bracket 30 is located at one end of the first guide segment 21 near the second guide segment 22. The drive mechanism 100 continues to drive the mounting bracket 30 to move, causing the first sliding part 331 to disengage from the first guide segment 21 and slide to be slidably connected to the second guide segment 22. The mounting bracket 30 as a whole begins to deflect. Subsequently, the drive mechanism 100 continues to drive the mounting bracket 30 to move. The first sliding part 331 moves under the guidance of the second guide segment 22, and the second sliding part 332 moves under the guidance of the first guide segment 21. The mounting bracket 30 as a whole continues to deflect.

[0044] In this embodiment, the first guide segment 21 has a relatively long extension length, and the first sliding part 331 and the second sliding part 332 can be slidably connected to the first guide segment 21 simultaneously, allowing the mounting bracket 30 to slide along the first direction A. The second guide segment 22 has a relatively short extension length, and the first sliding part 331 slides a certain distance under the guidance of the second guide segment 22 before reaching the end of the second guide segment 22. At this point, the second sliding part 332 is still slidably engaged with the first guide segment 22. In this embodiment, with the first sliding part 331 reaching the end of the second guide segment 22, the driver can more easily observe the content on the display 600.

[0045] In other embodiments, the extension length of the second guide segment 22 is set according to requirements. For example, the extension length of the second guide segment 22 is also relatively long. After the first sliding part 331 slides to the second guide segment 22, the drive mechanism 100 continues to drive the mounting bracket 30 to move. The mounting bracket 30 as a whole continues to deflect and gradually detaches from the first guide part 231 until the second sliding part 332 detaches from the first guide segment 21 and connects with the second guide segment 22. Then, the drive mechanism 100 drives the mounting bracket 30 to move along the second direction B.

[0046] Please see Figure 1 and Figure 2In this embodiment, the central control screen device 700 is mounted on the central control panel 930, and the drive mechanism 100 can drive the display 600 to deflect towards the driver's seat 910. Specifically, the base 10 is mounted on the central control panel 930, the guide assembly 20 is connected to the side of the base 10 away from the central control panel 930, the mounting bracket 30 is slidably mounted on the guide assembly 20, and the display 600 is mounted on the mounting bracket 30 and located on the side of the mounting bracket 30 away from the central control panel 930, so that the driver can easily observe the display screen of the display 600. In this embodiment, the direction from the passenger seat 920 to the driver's seat 910 is approximately the same as the extension direction (first direction A) of the first guide section 21. The first guide section 21 is approximately parallel to the base 10. The mounting bracket 30 has sliding connecting portions 33 on opposite sides, and the height of these two sides relative to the base 10 is approximately the same. Under the guidance of the first guide section 21, the mounting bracket 30 can move in a direction closer to the driver's seat 910 to shorten the distance between the driver's seat 910 and the display 600, so that the driver can observe or operate the display 600. When the driver observes or operates the display 600, the driver's body does not need to move or turn significantly, and the driver's field of vision does not need to shift significantly. The driver's field of vision can be switched quickly to ensure driving safety.

[0047] In this embodiment, the second guide segment 22 is connected to the end of the first guide segment 21 near the driver's seat 910. The first guide segment 21, the second guide segment 22 and the control device 800 are arranged in sequence. The second guide segment 22 is located between the first guide segment 21 and the control device 800. The second guide segment 22 extends relative to the first guide segment 21 in the direction close to the base 10. In practical applications, the sliding connection 33 (or the first sliding part 331) disengages from the first guide section 21 and slides to connect to the second guide section 22. The height of the side of the mounting bracket 30 closest to the driver's seat 910 relative to the base 10 decreases, creating a height difference between the opposite sides of the mounting bracket 30 and the base 10. This allows the mounting bracket 30 to have a deflected motion, causing the display screen of the monitor 600 to be tilted towards the driver's seat 910 and the driver. This facilitates the driver's quick identification and recognition of the content on the display screen, shortens the time the driver spends observing the monitor 600, and allows the driver to quickly take appropriate actions, reducing the time the driver spends operating the monitor 600, ensuring driving safety, and improving the user's driving experience. In other embodiments, the extension direction of the second guide section 22 relative to the first guide section 21 can be determined based on the actual relative positional relationship of the center console 930, base 10, guide assembly 20, mounting bracket 30, and other structures.

[0048] Please see Figure 7In this embodiment, the guide assembly 20 includes two guide members 23 arranged side by side, and a mounting bracket 30 located between the two guide members 23. The mounting bracket 30 is slidably connected to each of the two guide members 23. Each guide member 23 has a bent structure and includes at least two sequentially connected guide portions, with the extension directions of adjacent guide portions intersecting. Each guide member 23 includes a first guide portion 231 and a second guide portion 232 that are connected to each other, with the extension directions of the first guide portion 231 and the second guide portion 232 intersecting. The first guide portions 231 of both guide members 23 extend along a first direction A, and the two first guide portions 231 are arranged side by side to define a first guide segment 21; the second guide portions 232 of both guide members 23 extend along a second direction B, and the two second guide portions 232 are arranged side by side to define a second guide segment 22; the first guide portion 231 and the second guide portion 232 of each guide member 23 are connected to each other, so that the first guide segment 21 and the second guide segment 22 are connected to each other. In this embodiment, the mounting bracket 30 is located between the two guide members 23 and slides with each of the two guide members 23. The sliding connection between the mounting bracket 30 and the guide assembly 20 is relatively stable, which makes the movement of the mounting bracket 30 and the display 600 relatively smooth.

[0049] Please see Figure 7 and Figure 8 In this embodiment, the guide member 23 has a groove structure with multiple groove segments extending in different directions. The first guide portion 231 includes a first guide groove 2311, and the second guide portion 232 includes a second guide groove 2321. The first guide groove 2311 and the second guide groove 2321 are in communication with each other. In this embodiment, when the sliding connecting portion 33 is slidably connected to the first guide segment 21, the sliding connecting portion 33 can be slidably fitted into the two first guide grooves 2311 respectively. When the sliding connecting portion 33 is slidably connected to the second guide segment 22, the sliding connecting portion 33 can be slidably fitted into the two second guide grooves 2321 respectively.

[0050] To facilitate understanding of the structure of the mounting bracket 30, it is defined that the mounting bracket 30 has left and right sides and top and bottom sides. When the mounting bracket 30 cooperates with the first guide section 21, the left and right sides of the mounting bracket 30 are arranged along the first direction A, and the two guide members 23 are respectively located on the top and bottom sides of the mounting bracket 30. In an embodiment where the mounting bracket 30 has one sliding connection part 33, the sliding connection part 33 is located on the left (or right) side of the mounting bracket 30 to be close to the second guide section 22. In an embodiment where the mounting bracket 30 has two sliding connection parts 33, the two sliding connection parts 33 are distributed on the left and right sides of the mounting bracket 30, and the structure of each sliding connection part 33 is distributed on the top and bottom sides of the mounting bracket 30.

[0051] Please see Figure 4 In this embodiment, the sliding connection portion 33 includes two protrusion structures 333, which are located on the upper and lower sides of the mounting bracket 30 and respectively engaged with the corresponding guide members 23. In other embodiments, the sliding connection portion 33 may include two embedded shafts or embedded pins; or, the guide member 23 may be an elongated rod-shaped structure, and the sliding connection portion 33 may include two annular structures, which are slidably fitted onto the outer periphery of the rod-shaped structure. In this embodiment, the openings of the two first guide grooves 2311 are arranged opposite each other, the openings of the two second guide grooves 2321 are arranged opposite each other, and the two protrusion structures 333 of the sliding connection portion 33 are located on the upper and lower edges of the mounting bracket 30, respectively, and the connection between the mounting bracket 30 and the guide assembly 20 is relatively stable.

[0052] In some other embodiments, the guide assembly 20 may further include a third guide segment, which may be connected to the end of the first guide segment 21 away from the second guide segment 22. The extension direction of the third guide segment is different from the extension direction of the first guide segment 21, so that the mounting bracket 30 is in a deflected motion state as it moves from the first guide segment 21 to the third guide segment, allowing the mounting bracket 30 to have multiple motion states under the action of the guide assembly 20. In such embodiments, the extension direction of the third guide segment relative to the first guide segment 21 and the second guide segment 22 can be specifically set according to actual needs to limit the deflection direction of the mounting bracket 30 (and the display 600). In some other embodiments, the guide assembly 20 may include four or more guide segments.

[0053] Please see Figure 3 , Figure 4 and Figure 6In this embodiment, the mounting bracket 30 is rotatably connected to the drive assembly 40. When the mounting bracket 30 is in a deflected motion state, the mounting bracket 30 rotates relative to the drive assembly 40 about a specified axis P. The specified axis P is perpendicular to the extension direction of the first guide segment 21 and the extension direction of the second guide segment 22, respectively. When the mounting bracket 30 transitions from the first guide segment 21 to the second guide segment 22, the mounting bracket 30 deflects relative to the first guide segment 21. The mounting bracket 30 deviates from the first guide segment 21 and pushes the drive assembly 40 away from the first guide segment 21. In this embodiment, the mounting bracket 30 and the drive assembly 40 are rotatably connected, which can reduce the force exerted by the mounting bracket 30 on the drive assembly 40, prevent the drive assembly 40 from undergoing significant positional deflection or deformation, protect the structure of the drive assembly 40 and the base 10, and also prevent the structure of the drive assembly 40 from restricting the deflection of the mounting bracket 30. This allows the sliding connection portion 33 of the mounting bracket 30 to smoothly disengage from the first guide portion 231 and slidably connect with the second guide portion 232, enabling the drive mechanism 100 to effectively drive the mounting bracket 30 and the display 600 to deflect. In this embodiment, the drive assembly 40 is connected to the side of the mounting bracket 30 away from the second guide portion 232 to reduce the impact of the mounting bracket 30 on the drive assembly 40 during deflection.

[0054] In this embodiment, the drive mechanism 100 further includes a rotating connector 50, which includes a rotating shaft portion 51 and a connecting portion 52 connected to each other. The rotating shaft portion 51 has a cylindrical structure and is rotatably connected to the mounting bracket 30. The connecting portion 52 is connected to the drive assembly 40, so that the mounting bracket 30 and the drive assembly 40 are rotatably connected. In this embodiment, the mounting bracket 30 is provided with a rotating mating groove 314, and the rotating shaft portion 51 is rotatably mounted in the rotating mating groove 314. In the assembled state, the axial direction of the rotating shaft portion 51 is perpendicular to the extension direction of the first guide portion 231 and the extension direction of the second guide portion 232, respectively. In this embodiment, the rotating mating groove 314 is located on the side of the mounting bracket 30 away from the display 600, that is, the side facing the base 10, so that the central control screen device 700 is neater and more aesthetically pleasing. In this embodiment, a connecting rod 53 is connected between the rotating shaft portion 51 and the connecting portion 52. The connecting rod 53 extends relative to the rotating shaft portion 51 in a direction away from the mounting bracket 30, so that the connecting portion 52 is away from and avoids the mounting bracket 30, thereby preventing the connecting portion 52 from affecting the rotation of the rotating shaft portion 51.

[0055] Please see Figure 9 and Figure 10In this embodiment, the drive assembly 40 includes a rotary drive component 41, a gear 42, and a transmission component 43. The rotary drive component 41 is mounted on the base 10 and has an output shaft. The gear 42 is connected to the output shaft to rotate under the drive of the rotary drive component 41. The transmission component 43 meshes with the gear 42 to drive the mounting bracket 30. The transmission component 43 is connected to the connecting part 52, and its position relative to the connecting part 52 remains approximately unchanged. In this embodiment, the rotary drive component 41 may include a stepper motor, a servo motor, etc. In this embodiment, the transmission component 43 and the mounting bracket 30 can be both drive-connected and rotatably connected, making the position of the mounting bracket 30 relative to the drive assembly 40 more flexible. This reduces the impact of the mounting bracket 30's deflection on the drive assembly 40, and the transmission component 43 is driven through the meshing relationship, resulting in a more stable driving effect. In this embodiment, the rotary drive 41 is mounted on the side of the base 10 facing away from the mounting bracket 30, the output shaft passes through the base 10 and extends to the side of the base 10 facing the mounting bracket 30, and the gear 42 is located on the side of the base 10 facing the mounting bracket 30 and connected to the output shaft, and meshes with the transmission component 43. In other embodiments, the drive assembly 40 may have other types of drive methods, such as screw drive, hydraulic drive, etc.

[0056] Please see Figure 9 and Figure 10 In this embodiment, the transmission component 43 includes a flexible shaft 431, which has a connecting end (not shown in the figure) and a movable end 4318. The connecting end is connected to the base 10, and the movable end 4318 is connected to the connecting part 52. A helical structure 4311 is provided on the outer periphery of the flexible shaft 431, which meshes with the gear 42. In practical applications, the gear 42 rotates and meshes with the helical structure 4311, and the flexible shaft 431 moves along its axial direction (the extension direction of the flexible shaft 431) to drive the mounting bracket 30 to move. The flexible shaft 431 is lightweight, which makes the overall weight of the drive mechanism 100 lighter. The flexible shaft 431 is also flexible and easily deformable, resulting in less resistance to the deflection movement of the mounting bracket 30, which facilitates smoother deflection of the mounting bracket 30. In other embodiments, the transmission component 43 may be a gear 42, a chain, etc.

[0057] In this embodiment, there are two flexible shafts 431, which are respectively connected to the connecting part 52 and spaced apart from each other. The gear 42 is located between the two flexible shafts 431 and can mesh with at least one of the two flexible shafts 431 to ensure the stability of the transmission relationship. In some other embodiments, there may be only one flexible shaft 431. The flexible shaft 431 is relatively long, so when the mounting bracket 30 deflects, the offset of the flexible shaft 431 is small, preventing the flexible shaft 431 from disengaging from the gear 42. The base 10 may be provided with multiple fixing clips or other structures to hold the flexible shaft 431 and support it. In this embodiment, the transmission component 43 also includes a protective sleeve 432, through which the flexible shaft 431 passes, with the movable end 4318 exposed relative to the protective sleeve 432. The protective sleeve 432 can protect the spiral structure 4311 on the surface of the flexible shaft 431.

[0058] Please see Figure 9 In this embodiment, the mounting bracket 30 includes a sliding bracket 31. The two sliding connecting parts 33 mentioned above are located on the left and right sides of the sliding bracket 31, respectively. Multiple protrusion structures 333 are connected to the upper and lower sides of the sliding bracket 31, so that the sliding bracket 31 can be slidably mounted on the guide assembly 20. The mounting bracket 30 also includes a connecting bracket 32, which is connected to the display 600. The connecting bracket 32 ​​is detachably connected to the sliding bracket 31, for example, by snap-fit ​​connection or fastener through-connection. In this embodiment, the connecting bracket 32 ​​can be pre-installed with the display 600 and then installed on the sliding bracket 31, which facilitates the assembly of the drive mechanism 100 and the display 600.

[0059] In this embodiment, the sliding bracket 31 includes a main body 311, an extension 312, and a mating connection 313. The sliding connection 313 is disposed on the main body 311, and the rotating mating groove 314 is disposed on the main body. The main body 311 is slidably connected to the guide assembly 20. The extension 312 is connected between the main body 311 and the mating connection 313. The extension 312 extends relative to the main body 311 in a direction away from the base 10. The mating connection 313 is detachably connected to the connecting bracket 32. In this embodiment, the mating connection 313 is positioned away from and avoids the base 10, facilitating the connection between the mating connection 313 and the connecting bracket 32, and allowing the display 600 to move away from and avoid structures such as the guide assembly 20 and the base 10. In this embodiment, the specific structures of the extension 312 and the mating connection 313 are not limited, as long as their specific structures satisfy the connection and mating relationship described above.

[0060] This application provides a driving mechanism 100, which includes a base 10, a guide component 20, a mounting bracket 30, and a driving component 40. The guide component 20 is mounted on the base 10, and the mounting bracket 30 is used to mount a display 600. The mounting bracket 30 is slidably mounted on the guide component 20 and moves under the guidance of the guide component 20. The driving component 40 is mounted on the base 10 and is driven by the mounting bracket 30, driving the mounting bracket 30 to move. In this embodiment, the guide component 20 includes a first guide segment 21 and a second guide segment 22 that are connected to each other. The extension direction of the first guide segment 21 intersects the extension direction of the second guide segment 22, such that the movement direction of the mounting bracket 30 under the guidance of the first guide segment 21 is different from the movement direction of the mounting bracket 30 under the guidance of the second guide segment 22. The mounting bracket 30 is provided with at least one sliding connection part 33, which can be slidably connected to the first guide section 21 or the second guide section 22, so that the drive mechanism 100 can drive the mounting bracket 30 to move along the extension direction of the first guide section 21 or the second guide section 22. When the mounting bracket 30 transitions from the first guide section 21 to the second guide section 22, the mounting bracket 30 can deflect.

[0061] In this embodiment, the guide component 20 and the mounting bracket 30 can cooperate with each other to automatically drive the mounting bracket 30 and the display 600 to deflect. There is no need to set up an additional drive structure for driving the mounting bracket 30 to rotate. The number of components in the drive mechanism 100 is small, avoiding excessive weight of the drive mechanism 100 and reducing the cost of the drive mechanism 100. The mounting bracket 30 can deflect automatically without generating instructions to control the rotation of the mounting bracket 30, reducing the data calculation work of the background program, omitting the time for responding to control instructions, and improving the driving efficiency of the drive mechanism 100.
