DETAILED DESCRIPTION

[0028] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0029] Embodiment 1

[0030] As shown in Figure 1 and Figure 2 , the present embodiment provides a multi-dimensional adjusting mechanism for vehicle-mounted display, which comprises a slide rail 1, a slide base 2 is slidingly installed on the slide rail 1, and the slide rail 1 is connected with a center console through fixed seats 3 at both ends; the slide base 2 can be translated along the slide rail 1, and can be translated by a driver or a passenger, or can be translated by a motor and a lead screw, specifically, the motor is installed on the fixed seat 3, the lead screw driven by the motor is rotatably installed on the fixed seat 3 and penetrates through the slide base 2; this is prior art, which will not be described too much here; a spherical adjusting block 4 is installed on the slide base 2, and a display is connected with the adjusting block 4 through a connecting assembly 5; the connecting assembly 5 comprises a sleeve 501 fixedly connected to the adjusting block 4, a connecting rod 502 with a square cross section is slidingly installed in the sleeve 501, and an outer end of the connecting rod 502 is fixedly connected with the display; the connecting rod 502 can reciprocatingly slide under the limitation of the sleeve 501, so as to adjust the distance between the display and the center console, i.e. to adjust the distance between the display and the face of the passenger or the driver.

[0031] The adjusting block 4 can be rotated in different directions on the slide base 2 to ensure that the display can face the face of the driver or the passenger, it should be noted that the driver or the passenger can adjust the display by hand, but the amplitude of rotation of the adjusting block 4 is limited due to the positional relationship between the connecting assembly 5 and the slide base 2, and the amplitude of adjustment of the display is also limited; the adjustment of the display within the limited amplitude is sufficient to meet the demand of most people that the display faces their own face.

[0032] In addition, since the length and width of the display are inconsistent, the driver or passenger needs to adjust the display to different states, i.e. a horizontal state and a vertical state, in different use scenarios; for example, the display needs to be placed horizontally when watching a movie, and the display needs to be placed vertically when browsing a webpage; the driver or passenger can directly rotate the display, and the adjusting block 4 will rotate around the center line of the sleeve 501.

[0033] As shown in Figure 1 , Figure 3 and Figure 5 , the vehicle-mounted display multi-dimensional adjusting mechanism further comprises a limiting assembly 6 for limiting the adjusting block 4, so that the adjusting block 4 will not rotate relative to the sliding seat 2, thereby ensuring that the display will not rotate due to bumps transmitted to the vehicle during driving; the limiting assembly 6 comprises a limiting sleeve 601 fixedly connected to the surface of the adjusting block 4, a sliding block 602 slidably installed in the limiting sleeve 601, and two limiting blocks 603 fixedly installed on the sliding block 602 and extending to the outside of the limiting sleeve 601; the sliding seat 2 is provided with a cavity 201, the surface of the cavity 201 facing the adjusting block 4 is a partial spherical surface, and the virtual sphere where the spherical surface is located has the same center as the adjusting block 4; a plurality of limiting grooves 202 cooperating with the limiting blocks 603 are formed on the inner wall of the cavity 201; the end face of the limiting block 603 located outside the limiting sleeve 601 is hemispherical, and the limiting groove 202 is also hemispherical and cooperates with the end face of the limiting block 603; the distance between adjacent two limiting grooves 202 is equal to the distance between the two limiting blocks 603; in the initial state, the limiting block 603 is not in contact with the limiting groove 202, and the adjusting block 4 can freely rotate within a certain range; when the sliding block 602 drives the limiting block 603 to move outward under the action of an external force, the limiting block 603 approaches the spherical part of the inner wall of the cavity 201 and finally enters the limiting groove 202; since the end face of the limiting block 603 is hemispherical, and the limiting groove 202 is also hemispherical and cooperates with the end face of the limiting block 603, the limiting block 603 can enter the corresponding limiting groove 202 when the adjusting block 4 is rotated to different angles; it should be noted that the number of limiting grooves 202 is limited, and the angle of the display relative to the center console is different when the two limiting blocks 603 enter different limiting grooves 202; according to the number of limiting grooves 202, the number of states that the display can stably maintain is also different, and the number of stable states of the display that can be provided by the embodiment is sufficient to ensure the normal use of different drivers and passengers (i.e. to meet the requirement that the faces of the driver and the passenger are directly opposite the display).

[0034] It should be noted that during the process of slider 602 moving limit block 603 toward the spherical part of the inner wall of cavity 201, limit block 603 may not be able to be aligned with the corresponding limit groove 202. In this case, limit block 603 may be in contact with the inner wall of cavity 201 but not enter the limit groove 202. At this time, the driver or passenger only needs to gently rotate the display to make a slight adjustment to the angle of adjustment block 4 so that limit block 603 can enter the limit groove 202. After limit block 603 enters the limit groove 202, even if there are bumps during vehicle movement, adjustment block 4 can remain relatively stationary with slide block 2, thereby ensuring the relative stationarity of display and center console.

[0035] This embodiment also provides a display assembly, including the above-mentioned multi-dimensional adjustment mechanism for vehicle display.

[0036] Example 2

[0037] like Figure 2 As shown, based on the previous embodiment, the slide 2 of this embodiment has a threaded groove, and an internal threaded cylinder 604 is installed in the threaded groove. The axis of the internal threaded cylinder 604 passes through the center of the ball of the adjusting block 4, and the axis of the internal threaded cylinder 604 coincides with the center line of the connecting rod 502. A pressure ring 605 that coincides with its axis is fixedly installed on the internal threaded cylinder 604. The inner ring surface of the pressure ring 605 is in contact with the surface of the adjusting block 4, and a rubber sheet 606 is attached to the inner ring surface of the pressure ring 605.

[0038] After the driver or passenger adjusts the angle of the display with one hand, they reach behind the display with the other hand to rotate the internal threaded cylinder 604. During the rotation, the internal threaded cylinder 604 moves axially toward the slide block 2. The pressure ring 605 will rotate with the internal threaded cylinder 604 and move toward the slide block 2. Finally, the inner ring surface of the pressure ring 605 will fit against the surface of the adjusting block 4 located outside the slide block 2, pressing the adjusting block 4 tightly onto the slide block 2, further limiting the state of the adjusting block 4, and ensuring that the adjusting block 4 will not rotate relative to the slide block 2. The rubber sheet 606 increases the friction force on the adjusting block 4, further ensuring the stability of the adjusting block 4 during vehicle operation.

[0039] like Figure 2 , Figure 3 and Figure 4As shown, the slider 602 and the limiting sleeve 601 are fixedly connected with the extension spring 607, the slider 602 is fixedly installed with the control rod 608 extending to the inside of the adjusting block 4 and penetrating the ball center of the adjusting block 4, the end of the control rod 608 is fixedly installed with the circular control plate 609; the surface of the control plate 609 is uniformly fixedly installed with at least four driven sheets 610 along the circumference thereof, the adjusting block 4 is slidingly installed with the driving sheet 611 corresponding to the position of each driven sheet 610, the outer end of the driving sheet 611 is fixedly connected with the circular sheet 612; the circular sheet 612 is mostly located inside the adjusting block 4, and the rest is located outside the adjusting block 4, the circular sheet 612 can slide linearly in the adjusting block 4; when the control plate 609 slides toward the side of the limiting sleeve 601, the control rod 608 and the slider 602 follow the control plate 609 to move synchronously, the limiting block 603 will enter the corresponding limiting groove 202, and the extension spring 607 is stretched.

[0040] As shown in Figure 2 The end face of the driven sheet 610 close to the driving sheet 611 is semicircular, and the end face of the driving sheet 611 close to the driven sheet 610 is semicircular. In the initial state, the two are attached, and the attachment position can ensure that the driving sheet 611 can push the driven sheet 610 to slide toward the side of the adjusting block 4 when the driving sheet 611 slides toward the inside of the adjusting block 4, so as to drive the control plate 609 to slide toward the side of the limiting sleeve 601 through the driven sheet 610, thereby making the limiting block 603 enter the corresponding limiting groove 202.

[0041] It should be noted that no matter how the adjusting block 4 rotates, as long as the adjusting block 4 is within the rotation amplitude range, at least one circular sheet 612 can be attached to the circular sheet 612 and pushed to slide toward the inside of the adjusting block 4 during the rotation and movement of the inner threaded cylinder 604 to the adjusting block 4; as long as one circular sheet 612 slides toward the inside of the adjusting block 4, the corresponding driving sheet 611 can push all the driven sheets 610 and the control plate 609 to translate; in this way, the driver can realize the compression of the adjusting block 4 and the control of the limiting block 603 through the rotation of the inner threaded cylinder 604, which double guarantees the stability of the adjusting block 4; when the display angle needs to be changed, the driver or passenger only needs to rotate the inner threaded cylinder 604 in the opposite direction, the stretched extension spring 607 will automatically recover and drive the slider 602 to slide relative to the limiting sleeve 601 to reset, and the control rod 608, the control plate 609 and the driven sheet 610 are also reset; the driven sheet 610 pushes the driving sheet 611 and the circular sheet 612 to reset.

[0042] As shown in Figure 2 and Figure 4As shown, the surface of the sleeve 501 is provided with an air hole 503 communicating with the inside of the sleeve 501 at the position close to the adjusting block 4 on the side of the connecting rod 502; the surface of the connecting rod 502 towards the adjusting block 4 is fixedly provided with a sealing sheet 504; the control rod 608 penetrates the adjusting block 4 and extends into the inside of the sleeve 501, and a rubber block 613 is fixedly installed on the control rod 608 at the position corresponding to the air hole 503; when the driver or passenger pushes or pulls the display, the display will drive the connecting rod 502 to slide in the sleeve 501, and a gap is left between the connecting rod 502 and the end surface of the sleeve 501, so that the outside air can exchange with the air in the sleeve 501 at the left side of the left end surface of the connecting rod 502 through the gap; the outside air exchanges with the air in the sleeve 501 at the right side of the left end surface of the connecting rod 502 through the air hole 503; during the process that the driver or passenger adjusts the angle and the telescopic length of the display, the air hole 503 is in a smooth state; during the process that the driver or passenger rotates the inner threaded cylinder 604 after adjusting the angle and the telescopic length of the display, the control rod 608 will drive the rubber block 613 to move to the position corresponding to the air hole 503, the air hole 503 is blocked by the rubber block 613, and the outside air of the sleeve 501 cannot exchange with the air in the sleeve 501 through the air hole 503; since the air is difficult to be greatly compressed, the relative position of the connecting rod 502 and the sleeve 501 is not easy to change; in this way, in this embodiment, the driver realizes the compression of the adjusting block 4 by the compression ring 605 and the control of the limiting block 603 by the sliding block 602 through one action of rotating the inner threaded cylinder 604, so that the limiting block 603 enters into the corresponding limiting groove 202, and the telescopic position of the connecting rod 502 is also positioned by sealing the air hole 503, which greatly improves the convenience of adjustment.

[0043] Embodiment 3

[0044] As shown in Figure 6 , Figure 7 and Figure 8 , on the basis of the last embodiment, the fixed seat 3 in this embodiment is fixedly provided with a rack 7 parallel to the sliding rail 1, the sliding seat 2 is rotatably provided with a rotating shaft 8, the sliding seat 2 is further provided with a clamping assembly 9 for clamping the rotating shaft 8 so that the rotating shaft 8 cannot rotate, and the rotating shaft 8 is fixedly provided with a gear 10 engaged with the rack 7; the clamping assembly 9 comprises two clamping plates 901 symmetrically arranged on both sides of the rotating shaft 8 and slidingly installed on the surface of the sliding seat 2, and the end surface of the clamping plate 901 towards the rotating shaft 8 cooperates with the surface of the rotating shaft 8; the clamping plate 901 is fixedly provided with a first wedge-shaped block 902; the sliding seat 2 is slidingly provided with a sliding rod 903 at the position corresponding to each first wedge-shaped block 902, and the sliding rod 903 is parallel to the axis of the inner threaded cylinder 604; one end of the sliding rod 903 penetrates into the threaded groove of the inner threaded cylinder 604, and the other end of the sliding rod 903 is fixedly provided with a second wedge-shaped block 904 cooperating with the corresponding first wedge-shaped block 902; the sliding rod 903 in this embodiment is of elastic telescopic structure.

[0045] When the sliding seat 2 translates along the slide rail 1, the gear 10 and the rotating shaft 8 are in a rolling state, the clamping plate 901 does not apply pressure to the rotating shaft 8, and the clamping assembly 9 does not clamp the rotating shaft 8; when the driver or the passenger rotates the inner threaded cylinder 604 to move the inner threaded cylinder 604 axially towards the sliding seat 2, the end surface of the inner threaded cylinder 604 towards the sliding seat 2 will abut against the end surface of the sliding rod 903 and push the sliding rod 903 to translate axially along the inner threaded cylinder 604; in this process, the end surface of the sliding rod 903 rotates relative to the inner threaded cylinder 604 and an interaction force is generated between the end surface of the sliding rod 903 and the inner threaded cylinder 604; the sliding rod 903 translates synchronously with the second wedge block 904, and the second wedge block 904 pushes the corresponding first wedge block 902 and the clamping plate 901 to move towards the rotating shaft 8 until the clamping plate 901 abuts against and is pressed on the rotating shaft 8; as the driver or the passenger continues to rotate the inner threaded cylinder 604, the sliding rod 903 is compressed instead of translating, and correspondingly, the pressure transmitted by the sliding rod 903 to the first wedge block 902 and the clamping plate 901 through the second wedge block 904 also increases, and the clamping force applied by the clamping plate 901 to the rotating shaft 8 also increases, thereby limiting the rotation of the rotating shaft 8; the rotating shaft 8 cannot rotate, the gear 10 cannot rotate, and the sliding seat 2 cannot continue to translate along the slide rail 1, thereby achieving the positioning effect of the sliding seat 2.

[0046] In summary, in the embodiment, the driver or the passenger can realize four effects through the action of rotating the inner threaded cylinder 604: first, the compression of the adjusting block 4 by the compression ring 605 limits the relative rotation of the adjusting block 4 and the sliding seat 2; second, the control of the sliding block 602 on the limiting block 603 enables the limiting block 603 to enter the corresponding limiting groove 202, further ensuring that the adjusting block 4 cannot rotate relative to the sliding seat 2; both of the above limit the relative rotation of the display and the center console; third, the positioning of the extension position of the connecting rod 502 through the sealing air hole 503 ensures that the distance between the display and the center console does not change; fourth, the relative position of the sliding seat 2 and the center console is limited, ensuring that the sliding seat 2 and the display do not translate relative to the center console during vehicle driving.

[0047] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is self-evident that those skilled in the art can modify the described embodiments in various manners without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are merely illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
