[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Currently, there is only a mechanism on the market for rotating the central control screen, and there is no mass-produced model with a central control screen that can move laterally, that is, a sliding mechanism that can carry the central control screen for laterally movement has not yet been developed.

[0038] The embodiments of the present invention provide a sliding mechanism for lateral movement of a vehicle-mounted central control screen and a vehicle, which can solve the problem in the related art that as the co-pilot's demand for audio and video entertainment increases, adding a multimedia screen on the co-pilot side will significantly increase the cost of the entire vehicle.

[0039] See also Figure 1 , Figure 2 and Fig. 9 As shown, a sliding mechanism for lateral movement of a vehicle-mounted central control screen provided by an embodiment of the present invention may include: an integrated track 1, the integrated track 1 includes a main body 11 and two guide bars 12 connected to opposite sides of the main body 11, the main body 11 and the guide bar 12 are integrally formed, that is, the extension direction of the guide bar 12 can be the same as the extension direction of the main body 11, when the sliding mechanism is installed on the vehicle, the main body 11 and the guide bar 12 both extend along the width direction of the vehicle, and the main body 11 and the two guide bars 12 form a receiving space 13, that is, the top surface of the guide bar 12 will be higher than the top surface of the main body 11, which is convenient for guiding, and at the same time, the guide bars 12 located on both sides of the main body 11 and the surface of the main body 11 form the above-mentioned receiving space 13, and the guide bar 12 is provided with a sliding Block 14, the slider 14 can slide along the conductor, and the slider 14 can fit with the gap between the conductors; screw rod 2, the screw rod 2 is arranged in the receiving space 13, that is, the screw rod 2 can be partially or completely received in the receiving space 13, and the screw rod 2 is arranged in parallel with the guide bar 12, and a transmission block 21 is sleeved on the screw rod 2, one end of the screw rod 2 is connected to the driving mechanism 3, and the screw rod 2 can be driven to rotate around its axis by the driving mechanism 3, and the transmission block 21 sleeved on the screw rod 2 can be threadedly engaged with the screw rod 2, so that when the screw rod 2 rotates, the screw rod 2 can drive the transmission block 21 to realize lateral movement along the axis of the screw rod 2; and screen bracket 4, the screen bracket 4 is fixed to the slider 14, and the screen bracket 4 is fixed to the transmission block 21. The fixing here can be welding fixing or bolt fixing.

[0040] In the embodiment of the present invention, since the driving mechanism 3 can drive the screw rod 2 to rotate around its axis, the screw rod 2 will drive the transmission block 21 engaged with it to move laterally along the axis of the screw rod 2, and the screen bracket 4 is fixed to the transmission block 21. When the transmission block 21 moves laterally, it will drive the screen bracket 4 to achieve lateral movement, thereby realizing the movement of the screen bracket 4 between the main driving side and the co-pilot side. In addition, the screen bracket 4 is also fixed to the sliders 14 on both sides of the screw rod 2. The two sliders 14 are both mounted on the fixed guide bar 12. During the lateral movement of the screen bracket 4, the load can be transferred to the integrated track 1 through the sliders 14 on both sides, and the screen bracket 4 is constrained not to rotate around the axis of the screw rod 2, that is, there is only one degree of freedom; at the same time, since the screen bracket 4 is fixed on the transmission block 21 and the slider 14, after the screen bracket 4 fixes the vehicle-mounted central control screen, the transmission block 21 and the slider 14 can ensure the stability of the screen bracket 4 after it bears the load of the vehicle-mounted central control screen. When the co-driver needs to use the vehicle's central control screen, the driving mechanism 3 is used to drive the screen bracket 4 to move the vehicle's central control screen laterally to the co-driver's side. When the driver needs to use the vehicle's central control screen, the driving mechanism 3 is used to drive the screen bracket 4 to move the vehicle's central control screen in the opposite direction to the driver's side.

[0041] The present invention uses an integrated track 1, so that the two guide bars 12 on both sides of the main body 11 are integrally formed with the main body 11. After the integrated track 1 is formed, the relative position between the two guide bars 12 is fixed. In the subsequent assembly process, the two guide bars 12 will not move relative to each other, and there is no installation accuracy difference between them. After the integrated track 1 is installed, the parallelism between the two guide bars 12 is good, and the slider 14 is not prone to getting stuck due to changes in the spacing between the two guide bars 12 during the lateral movement between the two guide bars 12. Furthermore, when the vehicle-mounted central control screen is installed on the screen bracket 4, the vehicle-mounted central control screen will apply a load to the screen bracket 4. Since the screen bracket 4 is a cantilever structure extending from the integrated track 1 toward a side perpendicular to the length direction of the integrated track 1, the loads acting on the two guide bars 12 are unequal. For example, the load on the guide bar 12 on the side close to the vehicle-mounted central control screen will be relatively larger, and the load on the other guide bar 12 will be relatively smaller, causing the integrated track 1 to deform. In the present invention, since the guide bar 12 is integrally formed with the main body 11, when the integrated track 1 is deformed, the two guide bars 12 will deform at the same time, that is, even if the guide bar 12 is deformed subsequently, the difference between the two guide bars 12 after deformation is almost non-existent, further avoiding the jamming problem of the slider 14.

[0042] See also Figure 3 , Figure 4 and Figure 8As shown, in some embodiments, two sliders 14 may be sleeved on each guide bar 12, and the two sliders 14 on each guide bar 12 are arranged at intervals, so that the connecting line of the four sliders 14 on the two guide bars 12 forms a quadrilateral structure. That is, the four sliders 14 are spaced from each other, wherein the quadrilateral structure may be a rectangle, a diamond or other shapes. In this embodiment, the sliders 14 on the two guide bars 12 are decomposed into four points, which is equivalent to the four points (that is, the four sliders 14) moving on two straight lines (that is, the two guide bars 12). The movement of each slider 14 is not affected by other sliders 14. The four sliders 14 can tolerate parallelism during the movement on the guide bar 12, thereby improving the smoothness of sliding.

[0043] Preferably, the width of the slider 14 along the axial direction of the screw rod 2 is smaller than the width of the slider 14 along the radial direction of the screw rod 2. The larger width along the radial direction of the screw rod 2 can ensure a larger contact area between the slider 14 and the screen bracket 4, and ensure the stability of contact and force transmission, while the smaller width along the axial direction can minimize the size of the slider 14 along the axial direction of the screw rod 2. When viewed along the axial direction of the screw rod 2, the slider 14 is closer to a smaller point. When the width of the slider 14 along the axial direction of the screw rod 2 is longer, the movement of the slider 14 on the guide bar 12 is equivalent to the movement of one line (that is, the slider 14) and another line (that is, the guide bar 12). This will cause the slider 14 to maintain a high degree of parallelism with the guide bar 12 to achieve sliding. The slider 14 in this embodiment has a smaller width along the axial direction of the screw rod 2, and can almost be regarded as a point moving on the line. The slider 14 does not need to maintain a high degree of parallelism with the conductor to achieve smooth sliding.

[0044] In some embodiments, see Figure 3 and Figure 6As shown, the screen bracket 4 may have two first mounting plates 411, and the two first mounting plates 411 are respectively fixedly fitted with the two sliders 14, that is, the first mounting plates 411 are parallel to the surfaces of the sliders 14, so that the first mounting plates 411 can be fitted with the sliders 14; the screen bracket 4 may also be provided with a second mounting plate 412 between the two first mounting plates 411, and the second mounting plate 412 is recessed from the connection with the first mounting plates 411 in a direction away from the transmission block 21, so that the second mounting plates 412 form a cavity structure, that is, the two first mounting plates 41 1 are respectively located on opposite sides of the second mounting plate 412, and the positions of the two first mounting plates 411 are lower, and the position of the second mounting plate 412 is relatively higher. In this way, the height of the screen bracket 4 can be reduced as a whole when the screen bracket 4 is installed; the transmission block 21 is at least partially accommodated in the cavity structure, and the top surface of the transmission block 21 is fitted and fixed with the second mounting plate 412, wherein the fixation here can also be welding fixation or bolt fixation. Due to the limited space in the vehicle, the transmission block 21 and the screen bracket 4 are designed to overlap at least partially, which can reduce the overall height of the sliding mechanism and save space. That is, in this embodiment, the transmission block 21 does not penetrate the second mounting plate 412, and the transmission block 21 is located inside the second mounting plate 412 and is fitted and fixed with the inner wall surface of the second mounting plate 412.

[0045] In some preferred embodiments, see Figure 5 and Figure 7As shown, the screen bracket 4 has two first mounting plates 411, and the two first mounting plates 411 are respectively fixed to the two sliders 14, and the screen bracket 4 is also provided with a second mounting plate 412 between the two first mounting plates 411, and the second mounting plate 412 is recessed from the connection with the first mounting plates 411 in the direction away from the transmission block 21, so that the second mounting plate 412 forms a cavity structure; wherein, the second mounting plate 412 is also provided with a through hole 413 penetrating through its thickness, wherein one through hole 413 can be provided, and also a plurality of through holes 413 can be provided; the transmission block 21 is at least partially accommodated in the cavity structure, and the top of the transmission block 21 is inserted into the through hole 413, and the top of the transmission block 21 contacts the inner wall of the through hole 413. In this embodiment, the transmission block 21 can have four side walls all in contact with the inner wall of the through hole 413, or two or three side walls in contact with the inner wall of the through hole 413. Since the transmission block 21 basically moves along the axial direction of the screw rod 2 during use, the transmission block 21 will not slip out of the through hole 413 in the thickness direction of the screen bracket 4. Therefore, the transmission block 21 here contacts the inner wall of the through hole 413 to drive the screen bracket 4 to move, and there is no need to fix the transmission block 21 to the second mounting plate 412. In this arrangement, since the transmission block 21 and the second mounting plate 412 are not fixed, it can be ensured that the stress on the transmission block 21 will not be transmitted to the screen bracket 4. For example, when the screw rod 2 is deformed, the stress on the screw rod 2 will not be transmitted to the second mounting plate 412 through the transmission block 21.

[0046] In some optional embodiments, see Figure 1 and Figure 3 As shown, the two ends of the integrated track 1 are equipped with a reduction bearing seat 5, the reduction bearing seat 5 is provided with a worm gear, the worm gear is fixed to the screw 2, the reduction bearing seat 5 also includes a worm engaged with the worm gear, and the worm is connected to the driving mechanism 3. Among them, the driving mechanism 3 can be a motor or a hydraulic drive, etc. The driving mechanism 3 can drive the worm to rotate around its axis, and then drive the gear and the screw 2 to rotate through the worm. In this embodiment, by setting a worm gear structure, the rotation of the driving mechanism 3 can be reduced to achieve deceleration and distance increase.

[0047] For further information, see Figure 7As shown, the transmission block 21 can be accommodated in the accommodation space 13, so that the transmission block 21 and the integrated track 1 can at least partially overlap in the height direction, and the height of the sliding mechanism can be reduced while ensuring the volume of the transmission block; and the transmission block 21 can have a first sliding surface 211, and the main body 11 has a fitting surface 111, and the fitting surface 111 is arranged parallel to the first sliding surface 211. There is a gap between the first sliding surface 211 and the fitting surface 111, so as to avoid the friction between the first sliding surface 211 and the fitting surface 111 being large and hindering the movement of the transmission block 21.

[0048] See also Figure 4 , Figure 6 to Figure 7 As shown, in some embodiments, the cross section of the guide bar 12 is preferably circular, and the two opposite sides of the main body 11 further have side surfaces 112, and the side surfaces 112 are connected to the fitting surface 111 through the guide bar 12, wherein the fitting surface 111 can be the upper surface of the main body 11, and the side surfaces 112 are the front and rear side surfaces 112 of the main body 11; a matching cavity 141 can be provided in the slider 14, and the inner contour shape of the matching cavity 141 matches the outer contour shape of the guide bar 12, that is, the matching cavity 141 and the cross-sectional shape of the guide bar 12 are substantially the same, and the inner diameter of the matching cavity 141 is preferably larger than the outer diameter of the guide bar 12, so that the slider 14 and the guide bar 12 are in a uniform relationship. After the guide bar 12 is assembled, there is a gap between the slider 14 and the guide bar 12, and the slider 14 is clamped on the guide bar 12 through the matching cavity 141. One side of the slider 14 is also provided with an opening, and the width of the opening is smaller than the diameter of the matching cavity 141, that is, the central angle of the cross section of the matching cavity 141 is greater than 180 degrees, so as to prevent the slider 14 from falling off the guide bar 12 after being installed on the guide bar 12; the slider 14 is provided with a first contact surface 142 and a second contact surface 143 on opposite sides of the opening, respectively, the first contact surface 142 is parallel to the fitting surface 111, and the second contact surface 143 is parallel to the side surface 112. There is a gap between the first contact surface 142 and the fitting surface 111, and there is also a gap between the second contact surface 143 and the side surface 112.

[0049] In some optional embodiments, see Figure 1 and Fig. 9 As shown, the sliding mechanism may further include a base 6, the main body 11 is fixedly mounted on the base 6, and the plate surface of the main body 11 is in contact with the base 6, so that the contact area between the integrated track 1 and the base 6 is larger, and the integrated track 1 can transfer more load to the base 6; there is a gap between the bottom surface of the slider 14 and the base 6, wherein a gap is set between the slider 14 and the base 6 to ensure that the base 6 does not hinder the sliding of the slider 14.

[0050] In some embodiments, see Fig. 9 As shown, the sliding mechanism may also include a base 6 and a cover shell 7 mounted on the base 6, wherein the base 6 and the cover shell 7 may be connected by bolts, and the base 6 and the cover shell 7 form a receiving cavity, and the receiving cavity receives the integrated track 1 and the screw rod 2. Of course, the slider 14, the transmission block 21, etc. are also received in the receiving cavity; one side of the base 6 may be provided with a slot 61, and the slot 61 is connected to the receiving cavity, and the screen bracket 4 is fixed to the slider 14 through the slot 61. In this embodiment, the base 6 and the cover shell 7 are used to wrap all the components inside, and almost only the slot 61 structure can be seen from the outside, and the overall appearance is less affected. In addition, the reduction bearing seat 5 can be connected to the base 6 by bolts.

[0051] In some embodiments, see Figure 7 As shown, the transmission block 21 is further provided with a second sliding surface 212 and a third sliding surface 213, and the second sliding surface 212 and the third sliding surface 213 are respectively provided on opposite sides of the slider 14; each slider 14 is provided with a fourth sliding surface 144, and the fourth sliding surfaces 144 of the two sliders 14 are respectively parallel to the second sliding surface 212 and the third sliding surface 213. Wherein, the transmission block 21 can be arranged between two sliders 14 on two guide bars 12, so that the second sliding surface 212 and the third sliding surface 213 are opposite to the fourth sliding surface 144, and the transmission block 21 can also be arranged between two sliders 14 on the same guide bar 12, so that the second sliding surface 212 and the fourth sliding surface 144 are staggered, and the third sliding surface 213 and the fourth sliding surface 144 are staggered. When the second sliding surface 212 and the third sliding surface 213 are disposed opposite to the fourth sliding surface 144 , there is a gap between the second sliding surface 212 and the fourth sliding surface 144 , and there is a gap between the third sliding surface 213 and the fourth sliding surface 144 .

[0052] For further information, see Figure 6 and Figure 7 As shown, the second slip surface 212 is spaced apart from the first slip surface 211, and the second slip surface 212 is connected to the first slip surface 211 through a first connecting surface 214. When the second slip surface 212 is opposite to the fourth slip surface 144, the first connecting surface 214 and the corresponding fourth slip surface 144 and the fitting surface 111 form a first cavity; the third slip surface 213 is spaced apart from the first slip surface 211, and the third slip surface 213 is connected to the first slip surface 211 through a second connecting surface 215. When the third slip surface 213 is opposite to the fourth slip surface 144, the second connecting surface 215 and the corresponding fourth slip surface 144 and the fitting surface 111 form a second cavity.

[0053] Preferably, the screen bracket 4 may include a main screen bracket 41 and a sub-screen bracket 42. The main screen bracket 41 is arranged parallel to the screw rod 2 and the guide bar 12. The sub-screen bracket 42 is basically perpendicular to the main screen bracket 41. The sub-screen bracket 42 and the main screen bracket 41 can be connected by bolts. Of course, the sub-screen bracket 42 can also be arranged to be rotatable relative to the main screen bracket 41 to adjust the inclination angle of the vehicle-mounted central control screen. The vehicle-mounted central control screen can be installed on the sub-screen bracket 42.

[0054] Furthermore, the sliding mechanism of the embodiment of the present invention may also include a control panel 8 installed on the base 6 by bolts. The control panel 8 is connected to the drive mechanism 3 by signal. The control principle of the sliding mechanism is: after the control panel 8 receives the operation instruction, the drive mechanism 3 drives the screw rod 2 to rotate through the deceleration and torque increase with the reduction bearing seat 5, and the screw rod 2 drives the transmission block 21 to move laterally, and then the screen bracket 4 also moves laterally. In order to ensure the single degree of freedom of lateral movement and the stability after bearing the load of the screen, the screen bracket 4 is required to transfer the load to the integrated track 1 through the slider 14 and constrain it not to rotate, that is, it has only one degree of freedom.

[0055] The sliding mechanism provided in the embodiment of the present invention can meet the functional requirements of the lateral sliding of the vehicle-mounted central control screen required by the current market and customers, so that the car has a higher sense of technology and improves the brand's technological level; and the structure is simple and compact, and the integrated track 1 embeds the screw rod 2 and the transmission block 21 in the middle of the span, which can not only greatly improve the bearing torque, but also ensure the compactness of the space, and at the same time ensure the parallelism of the two guide bars 12; at the same time, the sliding mechanism has a modular adaptive design, which can adapt to the movement of different spans, can change the high cost of dual screens, and at the same time can bring a sense of ritual of on-demand movement.

[0056] An embodiment of the present invention further provides a vehicle, which includes a cab and a sliding mechanism installed in the cab for lateral movement of the above-mentioned vehicle-mounted central control screen, wherein the vehicle-mounted central control screen is fixedly provided on a screen bracket 4 of the sliding mechanism.
