Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise indicated, directional terms such as "upper, lower, left, right, front, rear" and the like are used to indicate an azimuth or a positional relationship based on that shown in the drawings, merely to facilitate description of the present disclosure and to simplify description, and do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth, as well as a specific azimuth configuration and operation, and thus should not be construed as limiting the present disclosure. Alternatively, the "up, down, left, right, front, rear" herein may be the same as the "up, down, left, right, front, rear" direction when the vehicle is in a normal running state. The inner and outer parts can be the inner and outer parts of the contour of the relevant parts.

Furthermore, unless otherwise indicated, terms such as "first" and "second" are used merely to distinguish one element from another element and are not of sequential or importance. In addition, the connection mentioned in the present disclosure may be directly connected or may be connected by using an intermediate member, which is not limited in the present disclosure.

The main reason that the existing display screen has poor stability in the open state is that the display screen is only supported by the root shaft (such as the second rotating shaft of the present disclosure) in the open state (such as the fully open state), so the stability is poor, and the display screen is not suitable for a large display screen.

In view of this, as shown in fig. 1 to 17, the present disclosure provides a mounting apparatus 100 for a display screen 200, the mounting apparatus 100 including a mounting base 10, a support bar 20, and a slider 30, the slider 30 being slidably disposed on the mounting base 10 along a first direction, the slider 30 being provided with a connection portion 31 (hereinafter, a second rotation axis) for hinging with the display screen 200, a first end of the support bar 20 being hinged with the mounting base 10, a second end of the support bar 20 being hinged with the display screen 200, the slider 30 being configured to, when moved along the first direction, enable the display screen 200 to be moved in the first direction and rotate the display screen 200 relative to the mounting base 10 about the first rotation axis, so that the display screen 200 is switched between a closed position (as in fig. 3) and a fully opened position (as in fig. 5).

When installed, the mount 10 may be attached to the roof of the vehicle cabin, with reference to fig. 1-5, and the display screen 200 has a closed position, a fully open position, and an intermediate position between the fully open and closed positions. When the display screen 200 needs to be switched between the closed position and the fully opened position, referring to fig. 1 to 3, the sliding member 30 is driven to slide in the first direction by driving the sliding member 30, or, referring to fig. 15 and 16, by driving the supporting rod 20 to rotate around the hinge point between the supporting rod 20 and the mounting base 10, the sliding member 30 is driven to slide in the first direction, so that the display screen 200 is driven to move in the first direction and rotate around the first rotation axis relative to the mounting base 10, so that the display screen 200 is switched between the closed position and the fully opened position.

In the mounting apparatus 100 provided in the present disclosure, since the support bar 20 is provided, the support bar 20 can also support the display screen 200 in addition to the connection portion 31 (e.g., the second rotation shaft) of the slider 30. Accordingly, the stability of the support of the display screen 200, particularly, the stability of the support when the display screen 200 is in the open state can be improved. The arrangement of the support bar 20 can improve the stability of the display screen 200 during the running of the vehicle when the vehicle is in a running state. Compared with the prior art in which only the scheme of rotating shaft support is adopted, the mounting device 100 provided by the present disclosure can promote the stability of the mounting of the display screen 200, so that the mounting device 100 can adapt to the display screen 200 with a larger size, in other words, the vehicle can adopt the display screen 200 with a larger size.

The present disclosure is not limited to the number of support bars 20 and sliders 30, and may have any number of support bars 20. Alternatively, as shown in fig. 1, 2, 16 and 17, in some embodiments of the present disclosure, the number of the support bars 20 is two, the two support bars 20 are spaced apart in the second direction, the two support bars 20 are used to support both ends of the display screen 200 in the second direction, the number of the sliders 30 may be two, the two sliders 30 are spaced apart in the second direction, and the two sliders 30 are used to hinge with both ends of the display screen 200 in the second direction, wherein the second direction intersects the first direction. Here, the first direction may be the same as the longitudinal direction (front-rear direction) of the vehicle, and the second direction may be the same as the width direction (left-right direction) of the vehicle. By providing the two support bars 20 and supporting both ends of the display screen 200, the reliability of supporting the display screen 200 can be further improved, so that the stability of the installation of the display screen 200 can be improved.

In the present disclosure, the hinge connection between the support rod 20 and the mounting base 10 may be referred to as a first hinge point), the hinge connection between the support rod 20 and the display screen 200 may be referred to as a second hinge point, and the hinge connection between the slider 30 and the display screen 200 may be referred to as a third hinge point. In order to smoothly switch the display screen 200 between the fully opened position and the closed position, referring to fig. 1 to 5, the connection portion 31 is provided for hinge points hinged with the display screen 200 and hinge point interval arrangement between the second end of the support lever 20 and the display screen 200. I.e. the third hinge point is spaced apart from the second hinge point on the display screen 200.

To further enhance the stability of the display screen 200 in the open state, optionally, as shown in fig. 1 and 16, the mounting apparatus 100 may be configured such that when the display screen 200 is in the open position, the hinge point between the support bar 20 and the mount 10 (i.e., the first hinge point), the hinge point on the support bar 20 for hinging with the display screen 200 (i.e., the second hinge point), and the hinge point on the slider 30 for hinging with the display screen 200 (i.e., the third hinge point) may be configured as three vertices of a triangle, i.e., the three hinge points of the first hinge point, the second hinge point, and the third hinge point are located at three vertex positions of the triangle, so that the support bar 20, the display screen 200, and the mount 10 may be structurally configured as a triangular support structure. The triangle support stability is good, and the stability of the display screen 200 in the running process of the vehicle can be effectively ensured.

The shape of the support rod 20 is not limited in this disclosure, alternatively, as shown in fig. 3 to 5, the support rod 20 may include a first arc-shaped section 201 and a second arc-shaped section 202 connected, where an end of the first arc-shaped section 201 away from the second arc-shaped section 202 is used for hinging with the mounting base 10, an end of the second arc-shaped section 202 away from the first arc-shaped section 201 is used for hinging with the display screen 200, the first arc-shaped section 201 protrudes in a direction away from the mounting base 10, and the second arc-shaped section 202 protrudes in a direction close to the mounting base 10. By the design, space is saved, and the structural compactness of the mounting device 100 is improved.

In general, mechanical devices cannot be tightly fitted for assembly or design reasons, and there may be a large gap between the parts that need to perform the rotation and the parts that are fixed relative thereto. The transmission precision between parts is possibly reduced, and the problems of impact noise, increased part wear and the like are caused by the existence of gaps.

In view of this, in order to eliminate the gap in the driving chain of the mounting apparatus 100, the compactness of the structure is improved, and optionally, as shown in fig. 1, 2 and 16, in some embodiments of the present disclosure, the mounting apparatus 100 further includes a torsion spring 40 for eliminating the gap, one of the second end of the support rod 20 and the display screen 200 is provided with a first rotation shaft 21, the other is provided with a first mounting hole 2203, the first rotation shaft 21 is used to pass through the first mounting hole 2203, for example, the second end of the support rod 20 is provided with the first rotation shaft 21, the display screen 200 is provided with the first mounting hole 2203, the support rod 20 is hinged to the display screen 200 through the first rotation shaft 21 or the first mounting hole 2203, the torsion spring 40 is sleeved on the first rotation shaft 21, and one end of the torsion spring 40 is connected to the support rod 20, and the other end is used to the display screen 200, wherein the axial direction of the first rotation shaft 21 is the same as the second direction.

By providing the torsion spring 40, the clearance of the driving chain of the mounting device 100 can be advantageously eliminated under the torsion force provided by the torsion spring 40, for example, referring to fig. 1 and 14, the clearance between the second end of the support rod 20 and the first lug 2201 on the display screen mounting seat 10 can be eliminated, and the clearance between the first end of the support rod 20 and the connecting position of the mounting seat 10 can be eliminated, thereby reducing abnormal noise during operation. In addition, the torsion spring 40 may also act to offset a portion of the weight of the display screen 200, facilitating a larger size display screen 200 to which the mounting apparatus 100 may be adapted.

As shown in fig. 6, the second end of the support rod 20 may be provided with a receiving groove 24, and the torsion spring 40 is at least partially disposed in the receiving groove 24, so that by providing the receiving groove 24, a space for accommodating the torsion spring 40 may not be reserved between the second end of the support rod 20 and a mounting portion (such as the first lug 2201) on the display screen 200, thereby being beneficial to saving space and improving structural compactness.

To avoid the first shaft 21 from being accidentally removed from the first mounting hole 2203, the mounting device 100 further includes a first stop nut 161, as shown in fig. 1 to 3, the first stop nut 161 being mounted on a portion of the first shaft 21 passing through the first mounting hole 2203 and configured to cooperate with the first ledge 2201 on the display screen 200 to avoid the first shaft 21 from being axially removed from the first mounting hole 2203.

The specific structure of the connection portion 31 of the slider 30 for connecting the display screen 200 is not limited in the present disclosure, alternatively, as shown in fig. 2 and 11, in one embodiment of the present disclosure, the connection portion 31 is configured as one of a second rotation shaft and a second mounting hole 2204, a central axis of the second rotation shaft is the first rotation axis, and the second rotation shaft is used to rotatably pass through the second mounting hole 2204, where the other one of the second rotation shaft and the second mounting hole 2204 is located on the display screen 200, for example, the connection portion 31 is configured as the second rotation shaft, and the second mounting hole 2204 is located on the display screen 200, and an axial direction of the second rotation shaft may be the same as the second direction.

In order to avoid the second shaft from being accidentally removed from the second mounting hole 2204, optionally, as shown in fig. 2, the mounting device 100 further includes a second stop nut 162, where the second stop nut 162 is mounted on a portion of the second shaft passing through the second mounting hole 2204 and is configured to cooperate with the second lug 2202 on the display screen 200, so as to avoid the second shaft from being axially removed from the second mounting hole 2204.

It will be appreciated that in other embodiments of the present disclosure, a snap ring may be employed in place of the second stop nut 162.

To enhance the degree of automation of the switching of the display screen between the closed and fully open positions, the mounting device 100 may further comprise a driving mechanism, see fig. 1 and 2, optionally for driving the slider 30 to slide in a first direction to move the display screen 200 in the first direction and rotate about a first rotation axis relative to the mounting base 10; alternatively, referring to fig. 16 and 17, the driving mechanism is configured to drive the support rod 20 to rotate about a hinge point (i.e., a first hinge point) between the support rod 20 and the mounting base 10, and drive the slider 30 to slide in a first direction, so as to drive the display screen 200 to move in the first direction and rotate about a first rotation axis relative to the mounting base 10.

It will be appreciated that in other embodiments of the present disclosure, no drive mechanism may be provided and that manual actuation of the display screen 200 between the closed and open positions may be employed.

The specific structure of the driving mechanism is not limited in the present disclosure as long as switching of the display screen 200 between the closed position and the fully open position can be achieved.
