Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

At present, only a mechanism capable of rotating the central control screen in a certain angle is available in the market, and no central control screen of a mass-production vehicle type can move transversely, namely a sliding mechanism capable of moving transversely for bearing the central control screen is not developed.

The embodiment of the invention provides a sliding mechanism for transverse movement of a vehicle-mounted central control screen and a vehicle, which can solve the problem that in the related art, along with the requirement of a passenger car on audio-video entertainment, a multimedia screen is added on the passenger car side, and the cost of the whole vehicle is greatly increased.

Referring to fig. 1, 2 and 9, a sliding mechanism for lateral movement of a vehicle central control panel according to an embodiment of the present invention may include: the integrated rail 1 comprises a main body 11 and two guide bars 12 connected to two opposite sides of the main body 11, the main body 11 and the guide bars 12 are integrally formed, that is, the extending direction of the guide bars 12 may be the same as the extending direction of the main body 11, when the sliding mechanism is installed on a vehicle, the main body 11 and the guide bars 12 both extend along the width direction of the vehicle, and the main body 11 and the two guide bars 12 enclose an accommodating space 13, that is, the top surface of the guide bars 12 is higher than the top surface of the main body 11, so that guiding is facilitated, meanwhile, the guide bars 12 located at two sides of the main body 11 and the surface of the main body 11 enclose the accommodating space 13, and the guide bars 12 are sleeved with sliders 14, the sliders 14 may slide along the conductors, and the sliders 14 may be in clearance fit with the conductors; the screw rod 2 is arranged in the accommodating space 13, that is, the screw rod 2 can be partially accommodated in the accommodating space 13 or can be completely accommodated in the accommodating space 13, the screw rod 2 is arranged in parallel with the guide bar 12, a transmission block 21 is sleeved on the screw rod 2, one end of the screw rod 2 is connected with the driving mechanism 3, the screw rod 2 can be driven to rotate around the axis of the screw rod 2 through the driving mechanism 3, and the transmission block 21 sleeved on the screw rod 2 can be in threaded engagement 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 transverse movement along the axis of the screw rod 2; and the screen support 4 is fixed with the sliding block 14, and the screen support 4 is fixed with the transmission block 21. The fixing here may be welding fixing or fixing by bolts.

In the embodiment of the invention, the driving mechanism 3 can drive the screw rod 2 to rotate around the axis of the screw rod 2, so that the screw rod 2 can drive the transmission block 21 meshed with the screw rod to transversely move along the axis of the screw rod 2, the screen support 4 is fixed with the transmission block 21, the transmission block 21 can drive the screen support 4 to transversely move together when transversely moving, so that the screen support 4 can move between a main driving side and an auxiliary driving side, the screen support 4 is also fixed with the sliding blocks 14 on two sides of the screw rod 2, the two sliding blocks 14 are sleeved on the fixed guide bars 12, and in the transverse moving process of the screen support 4, the load can be transmitted to the integrated track 1 through the sliding blocks 14 on the two sides, and the screen support 4 is restrained from rotating around the axis of the screw rod 2, namely, only has one degree of freedom; meanwhile, as the screen support 4 is fixed on the transmission block 21 and the sliding block 14, after the screen support 4 fixes the vehicle-mounted central control screen, the transmission block 21 and the sliding block 14 can ensure the stability of the screen support 4 after bearing the load of the vehicle-mounted central control screen. When the auxiliary driver needs to use the vehicle-mounted central control screen, the driving mechanism 3 is used for driving the screen support 4 to drive the vehicle-mounted central control screen to transversely move to the auxiliary driver side, and when the main driver needs to use the vehicle-mounted central control screen, the driving mechanism 3 is used for driving the screen support 4 to drive the vehicle-mounted central control screen to reversely move to the main driver side.

According to the invention, the integrated track 1 is used, so that the two guide bars 12 on the two sides of the main body 11 are integrally formed with the main body 11, after the integrated track 1 is formed, the relative positions of the two guide bars 12 are fixed, in the subsequent assembling process, the two guide bars 12 do not move relatively, and the two guide bars 12 are not poor in installation precision, so that after the integrated track 1 is installed, the parallelism between the two guide bars 12 is good, and the problem of clamping stagnation caused by the change of the distance between the two guide bars 12 is solved in the process that the sliding block 14 transversely moves between the two guide bars 12. Moreover, when the vehicle-mounted central control panel is mounted on the screen support 4, the vehicle-mounted central control panel applies a load to the screen support 4, and the screen support 4 is of a cantilever structure extending from the integrated rail 1 to one side perpendicular to the length direction of the integrated rail 1, so that the loads acting on the two guide bars 12 are unequal, for example, the load on the guide bar 12 close to the side of the vehicle-mounted central control panel is relatively large, and the load on the other guide bar 12 is relatively small, so that the integrated rail 1 deforms.

Referring to fig. 3, 4 and 8, in some embodiments, two sliders 14 may be sleeved on each of the guide bars 12, and the two sliders 14 on each of the guide bars 12 are spaced apart from each other, so that a connecting line of the four sliders 14 on the two guide bars 12 forms a quadrilateral structure. That is, the four sliders 14 are all spaced from each other, wherein the quadrilateral structure may be a rectangle, a diamond or other shape, in this embodiment, the sliders 14 on the two guide bars 12 are divided into four points, which is equivalent to that the four points (that is, the four sliders 14) move on two straight lines (that is, the two guide bars 12), the motion of each slider 14 is not affected by the other sliders 14, and the parallelism of the four sliders 14 can be maintained during the movement of the four sliders 14 on the guide bars 12, so that the smoothness of the sliding is improved.

Preferably, the width of the slider 14 in the axial direction of the lead screw 2 is smaller than the width of the slider 14 in the radial direction of the lead screw 2. Wherein, the width along the radial direction of the screw rod 2 is larger, which can ensure that the contact area of the slide block 14 and the screen bracket 4 is larger, ensure the stability of contact and force transmission, the width along the axial direction is smaller, so that the size of the slide block 14 along the axial direction of the screw rod 2 can be reduced as much as possible, and when viewed along the axial direction of the screw rod 2, the slide block 14 is closer to a smaller point, since the movement of the slide 14 on the bar 12 corresponds to the movement of one line (i.e., the slide 14) on the other line (i.e., the bar 12) when the width of the slide 14 in the axial direction of the screw 2 is long, this results in that the slide 14 must maintain a high degree of parallelism with the bar 12 to be slid, the width of the sliding block 14 in the axial direction of the screw rod 2 is small, and the sliding block can almost completely be regarded as a point moving on a line, and the sliding block 14 can realize smooth sliding without keeping high parallelism with a conductor.

In some embodiments, referring to fig. 3 and 6, the screen bracket 4 may have two first mounting plates 411, and the two first mounting plates 411 are respectively and correspondingly attached to the two sliders 14, that is, the first mounting plates 411 are parallel to the surface of the sliders 14, so that the first mounting plates 411 may be attached to the sliders 14; the screen bracket 4 may further include a second mounting plate 412 between the two first mounting plates 411, the second mounting plate 412 is formed by being recessed from a connection portion with the first mounting plates 411 to a direction away from the transmission block 21, so that the second mounting plate 412 encloses a cavity structure, that is, the two first mounting plates 411 are respectively located at two opposite sides of the second mounting plate 412, the positions of the two first mounting plates 411 are lower, and the position of the second mounting plate 412 is higher, so that the height of the screen bracket 4 can be integrally reduced when the screen bracket 4 is mounted; the transmission block 21 is at least partially accommodated in the cavity structure, the top surface of the transmission block 21 is fixedly attached to the second mounting plate 412, the transmission block 21 and the screen support 4 are at least partially overlapped due to limited space in the vehicle, and therefore the overall height of the sliding mechanism can be reduced, and space is saved. That is, in the present embodiment, the transmission block 21 does not penetrate the second mounting plate 412, and the transmission block 21 is positioned inside the second mounting plate 412 and is attached and fixed to the inner wall surface of the second mounting plate 412.

In this embodiment, the transmission block 21 may be in contact with the inner wall of the through hole 413 through four side walls, or in contact with the inner wall of the through hole 413 through two or three side walls, because the transmission block 21 basically moves along the axial direction of the screw rod 2 in the using process, the transmission block 21 does not separate from the through hole 413 in the thickness direction of the screen support 4, so the transmission block 21 contacts with the inner wall of the through hole 413, the screen support 4 can be driven to move, the transmission block 21 does not need to be fixed to the second mounting plate 412, and thus the transmission block 21 and the second mounting plate 412 are not fixed, so that the stress on the transmission block 21 can be ensured not to be transmitted to the screen support 4, for example, when the screw rod 2 deforms, the stress on the screw rod 2 cannot be transmitted to the second mounting plate 412 through the transmission block 21.
