DETAILED DESCRIPTION

[0067] The in-vehicle display device refers to a display screen installed inside a car. As an important interface for human-vehicle interaction, the in-vehicle display device mainly provides driving assistance and entertainment. In the prior art, most in-vehicle display devices are fixedly installed, and the angle of the display device screen cannot be adjusted.

[0068] In addition, the structure for realizing the rotation of the display device in the prior art is also relatively complex, with many parts, resulting in a complex assembly process. Therefore, this embodiment provides a display device to solve the above technical problems.

[0069] like Figure 1The figure shows a schematic diagram of the structure of the display device 1, which includes a bracket 11, a display device 12 and a drive assembly 13. The bracket 11 is used to be fixedly installed in the installation cavity of the instrument panel and / or the seat. Specifically, the bracket 11 may be provided with a mounting hole 111, and the installation cavity may be provided with a mounting groove (not shown in the figure). The bracket 11 is fixed in the installation cavity by connecting the mounting groove with a fixing member such as a screw or a bolt through the mounting hole 111. The display device 12 and the drive assembly 13 are both installed on the bracket 11, and the drive assembly 13 can drive the display device 12 to rotate relative to the bracket 11.

[0070] In this embodiment, the rotation angle of the display device 12 can be adjusted by controlling the driving component 13. For example, when the position of the display device 12 needs to be changed, the driving component 13 can be started by a control button (which can be a physical button or a virtual button displayed on the display device 12). The driving component 13 drives the display device 12 to rotate, thereby adjusting the viewing angle of the display device 12.

[0071] Specifically, Figure 2 FIG. 1 is a schematic diagram of the structure of the display device 12. The display device 12 includes a display module 122, a housing 121 for mounting the display module 122, and a first shaft portion 121b and a second shaft portion 121c located on both sides of the housing 121. The display module 122 is an electronic component for displaying images, text, and other information. The housing 121 is used to support the display module 122 and other electronic components (not shown in the figure). Figure 1 and Figure 2 The first shaft portion 121 b is connected to the driving assembly 13 , and the second shaft portion 121 c is rotatably mounted on the bracket 11 .

[0072] In this embodiment, the driving assembly 13 drives the first shaft portion 121b to rotate, and the first shaft portion 121b drives the housing 121 to rotate, so as to realize the rotation of the display device 12, thereby achieving the purpose of controlling the driving assembly 13 to adjust the rotation angle of the display device 12. At the same time, when the first shaft portion 121b drives the housing 121 to rotate, the second shaft portion 121c rotates synchronously with the housing 121, and the second shaft portion 121c supports the housing 121, so that the housing 121 is rotatably mounted on the bracket 11.

[0073] The driving assembly 13 is located at the side end of the display device 12 , and is fixedly connected to the bracket 11 . The bracket 11 is provided with an avoidance portion (not shown in the figure), and part of the first shaft portion 121b passes through the avoidance portion and is connected to the driving assembly 13 .

[0074] like Figure 3The figure shows a schematic diagram of the connection between the housing 121 and the first shaft portion 121b and the second shaft portion 121c. In some embodiments, at least one of the first shaft portion 121b and the second shaft portion 121c is formed integrally with the housing 121. That is, in this embodiment, the display device 12 is integrated with the first shaft portion 121b and / or the second shaft portion 121c, and then connected to the drive assembly 13 through the first shaft portion 121b to form a set of rotatable mechanisms to realize the rotation and sudden stop functions of the display device 12, thereby achieving the purpose of reducing the number of parts and simplifying the assembly process. In addition, this embodiment shortens the connection dimension chain, reduces tolerance accumulation, and improves assembly accuracy by adopting an integrated shaft design.

[0075] The shell 121, the first shaft portion 121b and the second shaft portion 121c may be specifically formed by: the shell 121, the first shaft portion 121b and the second shaft portion 121c may be integrally injection molded, so as to have the characteristics of fast molding, stable overall structure, high quality, cost saving, etc. Alternatively, the shell 121 and the first shaft portion 121b may be integrally injection molded, and the second shaft portion 121c may be fixed to the shell by auxiliary parts such as positioning tooling. Alternatively, the shell 121 and the second shaft portion 121c may be integrally injection molded, and the first shaft portion 121b may be fixed to the shell 121 by auxiliary parts such as positioning tooling. Alternatively, the shell 121, the first shaft portion 121b and the second shaft portion 121c may be molded separately, and after the shell 121, the first shaft portion 121b and the second shaft portion 121c are respectively molded, the first shaft portion 121b and the second shaft portion 121c may be coaxially fixed to the two sides of the shell 121 by auxiliary parts such as positioning tooling.

[0076] like Figure 4 The figure shows a schematic diagram of the driving assembly 13. In some embodiments, the driving assembly 13 is located at the side end of the display device 12. The driving assembly 13 includes a housing 131, a motor 132, a gear set (not shown in the figure) and a transmission member 133. The housing 131 is fixedly connected to the bracket 11. The motor 132, the gear set and the transmission member 133 are all mounted on the housing 131, and the gear set and the transmission member 133 can rotate relative to the housing 131. The driving end of the motor 132 is connected to the gear set, and the output end of the gear set is connected to the transmission member 133, and the transmission member 133 is connected to the first shaft portion 121b. The motor 132 drives the transmission member 133 to rotate by driving the gear set, and the transmission member 133 drives the first shaft portion 121b to rotate, thereby driving the display device 12 to rotate.

[0077] Among them, the motor 132 can adopt a damping motor, and the gear set is an existing gear assembly for realizing power transmission between two shafts that are far apart. It can be composed of multiple gears of different sizes. All gears maintain the same rotation speed to ensure transmission efficiency. The specific structure is not elaborated in this embodiment.

[0078] The following focuses on describing the specific connection structure between the first shaft portion 121 b and the transmission member 133 .

[0079] Please continue to refer to Figure 4 A groove 131a is provided on one side of the housing 131 facing the display device 12, and the transmission member 133 is provided in the groove 131a and can rotate relative to the groove 131a. Figure 3 and Figure 4 The transmission member 133 is provided with a matching groove 133a, and the first shaft portion 121b matches with the matching groove 133a to realize the connection between the transmission member 133 and the first shaft portion 121b, so that the transmission member 133 and the first shaft portion 121b rotate synchronously. In this embodiment, by providing the matching groove 133a on the transmission member 133, a part of the first shaft portion 121b is inserted into the matching groove 133a to achieve matching with the transmission member 133, which can reduce the matching space between the transmission member 133 and the first shaft portion 121b, which is conducive to reducing the overall volume of the display device 1 and reducing the installation space required for the display device 1.

[0080] Please continue to refer to Figure 3 and Figure 4 , along the direction where the first shaft portion 121b is connected to the second shaft portion 121c, the cross section of the first shaft portion 121b and the cross section of the matching groove 133a are non-circular, and the rotation axis of the first shaft portion 121b coincides with the rotation axis of the transmission member 133. In this embodiment, the matching surface of the first shaft portion 121b and the matching groove 133a is set to be non-circular, which can stop the matching of the transmission member 133 and the first shaft portion 121b, ensure accurate and stable transmission between the transmission member 133 and the first shaft portion 121b, and ensure the rotation accuracy of the display device 12.

[0081] Specifically, in some embodiments, along the direction in which the first shaft portion 121b is connected to the second shaft portion 121c, the cross section of the first shaft portion 121b and the cross section of the matching groove 133a can both be regular polygons. Exemplarily, the first shaft portion 121b can be a regular prism structure, and the cross section of the first shaft portion 121b is a regular polygon. Correspondingly, the cross section of the matching groove 133a is also a regular polygon, ensuring that the first shaft portion 121b and the matching groove 133a are matched. In this embodiment, by setting the cross sections of the first shaft portion 121b and the matching groove 133a to matching regular polygons, the first shaft portion 121b and the transmission member 133 are prevented from slipping during the transmission process, thereby ensuring the transmission efficiency of the transmission member 133 and the first shaft portion 121b. At the same time, it is conducive to achieving the coincidence of the rotation axis of the transmission member 133 with the rotation axis of the first shaft portion 121b, thereby ensuring the stability of the rotation of the display device 12.

[0082] Among them, Figure 4As shown, in this embodiment, the first shaft portion 121b can be a regular hexagonal prism, and the corresponding matching groove 133a is a regular hexagon. Alternatively, the first shaft portion 121b can also be a regular pentagonal prism, a regular heptagonal prism, a regular octagonal prism, etc., as long as the shape of the first shaft portion 121b matches the shape of the matching groove 133a.

[0083] Alternatively, in some embodiments, in the outer circumferential surface of the first shaft portion 121b and the inner side wall of the matching groove 133a, along the circumference of the first shaft portion 121b, one is provided with uniformly distributed protrusions (not shown in the figure), and the other is provided with uniformly distributed recesses (not shown in the figure), and the protrusions cooperate with the recesses. Exemplarily, the first shaft portion 121b can be a spline shaft structure, specifically an internal spline shaft or an external spline shaft. When the first shaft portion 121b is an external spline shaft, the outer circumferential surface of the first shaft portion 121b is uniformly provided with protrusions, which are key blocks, and the inner side wall of the matching groove 133a is uniformly provided with recesses, which are key slots. Through the cooperation of the key block and the key slot, the transmission member 133 can be kept to rotate synchronously with the first shaft portion 121b. When the first shaft portion 121b is an internal spline, the outer peripheral surface of the first shaft portion 121b is evenly provided with recessed portions, which are keyways, and the inner side wall of the matching groove 133a is evenly provided with raised portions, which are key blocks. The key blocks cooperate with the keyways to keep the transmission member 133 and the first shaft portion 121b rotating synchronously.

[0084] Alternatively, in some embodiments, the first shaft portion 121b and the matching groove 133a may also adopt other corresponding shapes to match each other to ensure that the first shaft portion 121b and the transmission member 133 rotate synchronously, which is not specifically limited in this embodiment.

[0085] like Figure 5 FIG. 1 is a cross-sectional view of a display device 1. Figure 6 for Figure 5 Schematic diagram of the matching position of the first shaft portion 121b and the transmission member 133. Figure 6 As shown, the first shaft portion 121 b cooperates with the transmission member 133 , and the two can be connected via a connecting member 134 .

Figure 8As shown, a weight-reducing hole 121b2 and a connecting groove 121b3 are also provided at one end of the first shaft portion 121b facing the bottom wall of the matching groove 133a. The connecting groove 121b3 is used to cooperate with the connecting member 134. The weight-reducing hole 121b2 and the connecting groove 121b3 will be described in detail below.

[0088] Fig. 9 FIG. 1 is a cross-sectional view of the drive assembly 13, which shows a cross-sectional view of the housing 131 and the transmission member 133. Fig. 9 As shown, the transmission member 133 is installed in the housing 131, and the transmission member 133 is provided with a matching groove 133a. The inner side wall of the matching groove 133a is provided with a second tapered surface 133a1, and the cross-sectional area of ​​the second tapered surface 133a1 gradually decreases in the direction away from the first shaft portion 121b. As shown in the figure, the bottom wall of the matching groove 133a is also provided with a connecting hole 133a2 for matching with the connecting member 134, and the housing 131 is also provided with an avoidance hole 131b, and the avoidance hole 131b is used to avoid the connecting member 134 from connecting the transmission member 133 and the first shaft portion 121b from the outside. The connecting hole 133a and the avoidance hole 131b will be described in detail below.

[0089] Please refer to Figure 6 , Figure 8 and Fig. 9 , the first conical surface 121b1 and the second conical surface 133a1 abut against each other when the first shaft portion 121b and the matching groove 133a are matched. In this embodiment, when the first shaft portion 121b and the matching groove 133a are matched, the first conical surface 121b1 and the second conical surface 133a1 are matched to achieve the taper match between the first shaft portion 121b and the transmission member 133, so that there is no matching gap between the first shaft portion 121b and the matching groove 133a, thereby ensuring the coaxiality of the transmission member 133 and the first shaft portion 121b.

[0090] Please continue to refer to Figure 6 , Figure 8 and Fig. 9 The driving assembly 13 includes a connecting member 134, which connects the transmission member 133 and the first shaft portion 121b to fix the transmission member 133 and the first shaft portion 121b. Specifically, a connecting hole 133a2 is provided on the bottom wall of the matching groove 133a, and a connecting groove 121b3 is provided on one end of the first shaft portion 121b facing the bottom wall of the matching groove 133a. The connecting member 134 can pass through the connecting hole 133a2 and connect with the connecting groove 121b3 to fix the transmission member 133 and the first shaft portion 121b, thereby further ensuring stable transmission of the transmission member 133 and the first shaft portion 121b.

[0091] The connecting member 134 may be a bolt, a screw or the like, and the inner wall of the connecting hole 133a2 and the connecting groove 121b3 may be provided with threads. At least two connecting members 134 may be provided, for example, three or four connecting members 134 may be provided.
