[0028] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0029] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0030] In a vehicle, the central control screen is a display screen located in the cab that can adjust the air conditioning, audio, etc. inside the vehicle. Some applications can only be used in portrait mode, so in many current vehicles, the central control screen can be rotated. In related technologies, a drive motor and mechanical transmission components such as a reducer and a gear rack are connected to the vehicle body, and the transmission component is connected to the central control screen. The drive motor drives the transmission component to move, thereby driving the central control screen to rotate.

[0031] However, in the above-mentioned vehicles, the central control screen can only be driven to rotate by a driving motor. It is understandable that when the motor is controlled, the motor can be started or stopped by triggering a button on the central control screen. For some special groups, such as the elderly, they may not be able to use the central control screen proficiently, which makes the central control screen less convenient to use.

[0032] Therefore, the embodiment of the present application provides a vehicle, which changes the mechanical transmission mode of the central control screen to a magnetic force driving the central control screen to rotate, so that the central control screen can be driven to rotate not only in an active manner, that is, driven to rotate by a motor, but also in a passive manner, for example, by applying an external force on the central control screen. In this way, for some special people, even if they cannot operate the central control screen, they can still realize the rotation of the central control screen.

[0033] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] See also Figures 1 to 3 , Figure 1 A three-dimensional schematic diagram of a partial structure of a vehicle provided in an embodiment of the present application, Figure 2 for Figure 1 A schematic diagram of the local structure of Figure 3 for Figure 2 A schematic diagram of the enlarged local structure at A in the middle. As shown in the figure, this embodiment provides a vehicle, including a vehicle body and a central control screen 1, a cab is formed at the front of the vehicle body (not shown in the figure), and the central control screen 1 is located in the cab. As can be seen from the above, in some specific scenarios, the central control screen 1 needs to be rotated to a vertical screen state for use, so the central control screen 1 can be rotatably connected to the vehicle body. In this embodiment, specifically, the central control screen 1 is rotatably connected to the vehicle body through the first rotating part 2.

[0035] Generally, in order to rotate the central control screen 1, a corresponding driving mechanism needs to be set up, and the rotation of the central control screen 1 is realized by the driving of the driving mechanism. As can be seen from the above, when the central control screen 1 can only be driven to rotate by the driving mechanism, it will make the use of the central control screen 1 less convenient for some specific people.

[0036] Therefore, the vehicle provided in this embodiment also includes a driving mechanism 3, a first magnetic part 4 and a second magnetic part 5. The driving mechanism 3 is connected to the vehicle body and has a second rotating part 31 that can rotate; the first magnetic part 4 is arranged on the first rotating part 2; the second magnetic part 5 is arranged on the second rotating part 31, and is arranged opposite to and interacts with the first magnetic part 4; wherein, when the second rotating part 31 rotates, it can drive the first rotating part 2 to rotate through the magnetic force generated between the first magnetic part 4 and the second magnetic part 5, thereby driving the central control screen 1 to rotate.

[0037] Thus, by providing the driving mechanism 3, the first magnetic member 4 and the second magnetic member 5, not only the central control screen 1 can be driven to rotate by the driving mechanism 3, but also, when the driving mechanism 3 is not working, the central control screen 1 can be rotated by applying an external force to the central control screen 1, for example, by applying an external force to the central control screen 1 by hand. This arrangement allows some specific groups of people, such as the elderly, to rotate the central control screen 1 without touching the central control screen 1 or pressing a button, thereby improving the convenience of using the central control screen 1.

[0038] In addition, when the driving mechanism 3 is damaged and cannot work normally, external force can be applied to the central control screen 1 to drive the central control screen 1 to rotate, so as to improve the performance of the vehicle provided in this embodiment.

[0039] Moreover, in the related art, if the central control screen is blocked by an obstacle and cannot rotate, the drive motor may still be working. At this time, the transmission components such as gears and racks connected between the drive motor and the central control screen cannot move normally, which will cause wear, shortening the service life of the transmission components and further shortening the service life of the drive mechanism. In the present embodiment, there is no provision of transmission components such as gears and racks. Even if the central control screen 1 is blocked by an obstacle and cannot be driven to rotate by the drive mechanism 3, at this time, since the first magnetic part 4 and the second magnetic part 5 cooperate with each other through magnetic force and do not need to contact, the wear and tear in the related art will not occur. In this way, the service life of the drive mechanism 3, the first magnetic part 4 and the second magnetic part 5 that drive the central control screen 1 to rotate in the present embodiment is longer, so that the central control screen 1 can maintain normal rotation for a long time.

[0040] It can be understood that if you want to drive the first rotating part 2 to rotate by the magnetic force generated between the first magnetic part 4 and the second magnetic part 5, then the magnetic poles of the side of the first magnetic part 4 facing the second magnetic part 5 and the side of the second magnetic part 5 facing the first magnetic part 4 should be opposite. For example, if the magnetic pole of the side of the first magnetic part 4 facing the second magnetic part 5 is the north magnetic pole N, then the magnetic pole of the side of the second magnetic part 5 facing the first magnetic part 4 is the south magnetic pole S; if the magnetic pole of the side of the first magnetic part 4 facing the second magnetic part 5 is the south magnetic pole S, then the magnetic pole of the side of the second magnetic part 5 facing the first magnetic part 4 is the north magnetic pole N.

[0041] Among them, the driving mechanism 3 can be a motor, and the second rotating part 31 can be connected to the motor shaft of the motor or formed by part of the motor shaft of the motor; it can also be a form of a motor combined with a transmission assembly, the motor is connected to the transmission assembly, the transmission assembly is connected to the second rotating part 31, or a partial structure of the transmission assembly forms the second rotating part 31, and the transmission assembly is driven to move by the rotation of the motor shaft of the motor, thereby driving the second rotating part 31 to rotate.

[0042] In a specific implementation of this embodiment, the driving mechanism 3 includes a driving member 32 and a transmission assembly 33, both of which are connected to the vehicle body; the second rotating part 31 is formed on the transmission assembly 33, and the driving member 32 is used to drive the transmission assembly 33 to move to drive the second rotating part 31 to rotate.

[0043] Among them, the driving member 32 can drive the motor, and since the rotation speed of the motor shaft of the motor is relatively fast, the central control screen 1 does not need a faster rotation speed. Therefore, the transmission assembly 33 can be a worm gear reducer, and the motor shaft of the driving motor is connected to the input shaft of the worm gear reducer; part of the structure of the output shaft of the worm gear reducer forms the second rotating part 31, or the second rotating part 31 is connected to the output shaft of the worm gear reducer.

[0044] In a specific implementation of this embodiment, in order to reduce the manufacturing cost of the driving mechanism 3, the second rotating portion 31 is formed by a partial structure of the output shaft of the worm gear reducer.

[0045] In this way, the active rotation of the central control screen 1 can be achieved through the cooperation between the motor and the worm gear reducer.

[0046] It should be noted that in this embodiment, the motor can be electrically connected to the control module of the vehicle, and corresponding function buttons can be set on the central control screen 1 to control the start and stop of the motor. Here, there is no specific restriction on the control method of the motor.

[0047] Furthermore, in some cases, such as when the vehicle is bumpy, if the first magnetic component 4 and / or the second magnetic component 5 is hit, the magnetism of the first magnetic component 4 and / or the second magnetic component 5 may be attenuated. When the magnetism of either the first magnetic component 4 or the second magnetic component 5 is attenuated, when the second rotating part 31 rotates, the uncertainty of whether the magnetic force between the first magnetic component 4 and the second magnetic component 5 can drive the first rotating part 2 to rotate will increase. Therefore, in order to avoid this situation, in some embodiments, the first rotating part 2 is provided with a plurality of first magnetic components 4 distributed at intervals along its circumference, and the second rotating part 31 is provided with a plurality of second magnetic components 5 distributed at intervals along its circumference; the plurality of first magnetic components 4 and the plurality of second magnetic components 5 are arranged in a one-to-one correspondence.

[0048] In this way, even when the magnetism of one or several first magnetic parts 4 and / or the second magnetic parts 5 decays, it is difficult to affect the rotation of the first rotating part 2. At this time, the magnetic force generated between the remaining first magnetic parts 4 and the second magnetic parts 5 can still enable the second rotating part 31 to drive the first rotating part 2 to rotate, and then drive the central control screen 1 to rotate, so that the central control screen 1 can maintain normal rotation for a long time.

[0049] From the above, it can be seen that in the related art, the transmission assembly connected between the motor and the central control screen may fail due to wear. In an optional implementation of the present embodiment, in order to avoid the occurrence of this phenomenon to a greater extent, it is necessary to maintain a certain distance between the first magnetic part 4 and the second magnetic part 5, and to maintain a certain distance between the second rotating part 31 and the first rotating part 2.

[0050] Therefore, the vehicle provided in this embodiment further includes a thrust bearing 6, and the first rotating part 2 and the second rotating part 31 are arranged at intervals along the axial direction of the thrust bearing 6 and sleeved on the thrust bearing 6; wherein, the first magnetic part 4 and the second magnetic part 5 are arranged relative to each other in the axial direction of the thrust bearing 6 and have a spacing. In this way, through the setting of the thrust bearing 6, a certain spacing can be maintained between the first magnetic part 4 and the second magnetic part 5 and between the first rotating part 2 and the second rotating part 31, which can avoid wear between the first magnetic part 4 and the second magnetic part 5 and between the first rotating part 2 and the second rotating part 31 to a certain extent, improve the rotation performance of the central control screen 1, and at the same time, the first rotating part 2 and the second rotating part 31 can still maintain normal relative movement.

[0051] Please combine Figure 4 , Figure 4 for Figure 2Cross-sectional view along the axial direction. In order to enable both the first rotating part 2 and the second rotating part 31 to be sleeved on the thrust bearing 6, in this embodiment, a first mounting hole 22 is provided on the side of the first rotating part 2 facing the second rotating part 31, and a second mounting hole 312 is provided on the side of the second rotating part 31 facing the first rotating part 2, and both ends of the thrust bearing 6 extend into the first mounting hole 22 and the second mounting hole 312 respectively.

[0052] In order to make the magnetic force generated between each set of relative first magnetic parts 4 and second magnetic parts 5 approximately equal, so that the central control screen 1 can rotate at a uniform speed, in some embodiments, multiple first magnetic parts 4 have the same shape and volume, and multiple second magnetic parts 5 have the same shape and volume. In this way, the magnetic force generated by each set of relative first magnetic parts 4 and second magnetic parts 5 is equal in an ideal state, so that the stability of the central control screen 1 during the rotation process can be improved, so as to enhance the experience of the central control screen 1.

[0053] Furthermore, in order to facilitate the arrangement of the first magnetic member 4 and the second magnetic member 5, in some embodiments, the first magnetic member 4 and the second magnetic member 5 have the same shape and the same volume. In this way, when the first magnetic member 4 is arranged on the first rotating part 2 and the second magnetic member 5 is arranged on the second rotating part 31, it is convenient to determine the positions of the first magnetic member 4 and the second magnetic member 5, which can improve the installation efficiency of the first magnetic member 4 and the second magnetic member 5.

[0054] It should be noted that the first magnetic member 4 can be bonded to the first rotating part 2, and the second magnetic member 5 can be bonded to the second rotating part 31. Here, the connection method between the first magnetic member 4 and the first rotating part 2 and the connection method between the second magnetic member 5 and the second rotating part 31 are not specifically limited.

[0055] In this embodiment, both the first magnetic member 4 and the second magnetic member 5 are permanent magnets. In some other embodiments, the first magnetic member 4 and the second magnetic member 5 may also be other magnetic members, as long as magnetic force can be generated between the first magnetic member 4 and the second magnetic member 5. Here, there is no specific limitation on the types of the first magnetic member 4 and the second magnetic member 5.

[0056] Please combine Figure 5 and Figure 6 , Figure 5 A schematic diagram of the positional relationship between the first rotating part and the second rotating part in a vehicle provided in an embodiment of the present application, Figure 6 for Figure 5 Cross-sectional view along direction BB.

[0057] It can be understood that the magnitude of the magnetic force generated between the first magnetic part 4 and the second magnetic part 5 is also related to the distance between the first magnetic part 4 and the second magnetic part 5. In the present embodiment, if the distance between any two relative groups of the first magnetic part 4 and the second magnetic part 5 is inconsistent, it will also affect the rotation speed of the central control screen 1 during the rotation process, and reduce the stability of the central control screen 1 during the rotation process.

[0058] Therefore, in order to make the distance between each relatively arranged first magnetic member 4 and second magnetic member 5 equal, in some optional embodiments, the first rotating part 2 has a first end face 21 arranged facing the second rotating part 31, the second rotating part 31 has a second end face 311 arranged facing the first rotating part 2, and the first end face 21 is arranged in parallel with the second end face 311; the first magnetic member 4 is arranged on the first end face 21, and the second magnetic member 5 is arranged on the second end face 311. In this way, when the first end face 21 is parallel to the second end face 311, and when multiple first magnetic members 4 have the same shape and equal volume, and multiple second magnetic members 5 have the same shape and equal volume, the distance between multiple relatively arranged first magnetic members 4 and second magnetic members 5 can be kept consistent, so that the magnitude of the magnetic force generated between each relatively arranged first magnetic member 4 and second magnetic member 5 is consistent. In this way, the stability of the central control screen 1 during the rotation process can be further improved.

[0059] In order to realize the rotational connection between the first rotating part 2 and the vehicle body and the fixation of the driving mechanism 3, in this embodiment, the vehicle body includes a vehicle body main body (not shown in the figure) and a fixing plate 7 connected to the vehicle body main body; the fixing plate 7 has a first transfer hole 71, and the first rotating part 2 is rotationally connected to the first transfer hole 71 and connected to the central control screen 1 through the first transfer hole 71. In this way, the rotational connection between the first rotating part 2 and the vehicle body can be realized, and then the rotational connection between the central control screen 1 and the vehicle body can be realized.

[0060] Please combine Figure 7 , Figure 7 for Figure 1 In order to achieve the connection between the central control screen 1 and the first rotating part 2, the vehicle provided in this embodiment also includes a connecting plate 8, the central control screen 1 is mounted on the connecting plate 8; the first rotating part 2 is connected to the connecting plate 8 through the first adapter hole 71.

[0061] Specifically, the connecting plate 8 is detachably connected to the first rotating part 2, for example, detachably connected via threaded fasteners, and the central control screen 1 is detachably connected to the connecting plate 8, and may also be detachably connected via threaded fasteners.

[0062] Furthermore, the connecting plate 8 may include a first connecting plate 81 and a second connecting plate 82 that are perpendicular to each other, the first connecting plate 81 is arranged parallel to the fixing plate 7 and is detachably connected to the first rotating part 2, and the central control screen 1 is detachably connected to the second connecting plate 82. Here, the shape of the connecting plate 8 is not specifically limited.

[0063] In order to facilitate the assembly of the first rotating part 2 of the driving mechanism, the driving mechanism 3 and the connecting plate 8, measures such as reducing the mass can be adopted. For example, in this embodiment, the first rotating part 2 and the second rotating part 31 are both hollow structures, and a weight-reducing hole 811 corresponding to the inner hole of the first rotating part 2 is opened on the first connecting plate 81. In this way, the assembly efficiency of the vehicle provided by this embodiment can be improved.

[0064] Specifically, the inner hole of the first rotating part 2 also includes a first weight-reducing hole section 23 connected to the first mounting hole 22, and the inner hole of the second rotating part 31 also includes a second weight-reducing hole section 313 connected to the second mounting hole 312, and the aperture of the first mounting hole 22 is larger than the aperture of the first weight-reducing hole section 23, and the aperture of the second mounting hole 312 is larger than the aperture of the second weight-reducing hole section 313.

[0065] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
