Description

[[Technical Field]]

[0001] The present disclosure relates to a display device and a mounting member. [[Background Art]]

[0002] In recent years, with the popularization of vehicle driving assistance systems, imaging devices are increasingly being mounted on vehicles. In addition, an imaging device and an electronic mirror are mounted in the vehicle compartment, and an image of the rear of the vehicle captured by the imaging device is displayed on the electronic mirror. For example, the electronic mirror is attached to a vehicle-side base via an attachment member fixed to the electronic mirror. [[Prior Art Literature]] [[Patent Literature]]

[0003] [[Patent Document 1]] US Patent No. 10190610 Specification [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] For example, when the mounting member is a leaf spring and structured to be fixed to the electronic mirror, since the electronic mirror is heavy, it is necessary to increase the spring load of the mounting member. In addition, when the spring load is high, the mounting member requires a large force when attaching the mounting member to the vehicle-side base. Therefore, for example, when attaching an electronic mirror to a vehicle-side base, an operator needs to perform the attachment work using a jig, which leads to deteriorated workability and increased process load, so there is room for further improvement.

[0005] The present disclosure provides a display device and a mounting member that can reduce the number of work steps. [[Means for Solving the Problem]]

[0006] The display device according to this disclosure comprises a support member, a mounting member, and a fixing member. The support member supports a housing that encloses a display panel. The mounting member comprises a plurality of arms. The fixing member fixes the support member and the mounting member. Each arm has a first opening into which a projection of the support member is inserted, and the first width, which is the horizontal dimension from one end of the arm to one end of the first opening, is different from the second width, which is the horizontal dimension from one end of the arm to the other end of the arm that is different from one end of the first opening. [Effects of the Invention]

[0007] The display device and mounting member described herein can reduce the amount of work required. [Brief explanation of the drawing]

[0009] Hereinafter, embodiments of the display device according to this disclosure will be described with reference to the drawings.

[0010] (Embodiment) Figure 1 is a schematic diagram showing an example of an electronic mirror system 3 according to an embodiment. Figure 1 shows a vehicle 5 on which the electronic mirror system 3 is installed. The electronic mirror system 3 comprises an imaging device 1 and an electronic mirror 2.

[0011] The imaging device 1 is an on-board camera mounted on the vehicle 5 and is installed on the outside or inside of the vehicle body 6. The imaging device 1 may be installed at the rear end of the vehicle body 6 to capture images of the rear, at the end near the door of the vehicle body 6 to capture images of the side, or at the front end of the vehicle body 6 to capture images of the front.

[0012] The electronic mirror 2 is located inside the vehicle compartment 7. The electronic mirror 2 is an example of a display device. The electronic mirror 2 has a display panel 21, and can display images acquired by the imaging device 1 on the display panel 21. The display panel 21 is an example of a display panel. The electronic mirror 2 is configured to be switchable between display mode and mirror mode. In display mode, the display panel on the electronic mirror 2 displays images captured by the imaging device 1, and the electronic mirror 2 functions as a display. In mirror mode, the display panel on the electronic mirror 2 is turned off, and the electronic mirror 2 functions as a mirror.

[0013] Figure 1 illustrates a configuration in which the imaging device 1 is installed on the rear end 61 of the vehicle body 6, and the electronic mirror 2 is applied to an electronic mirror system for rearward visibility. The electronic mirror system for rearward visibility is also called an electronic rearview mirror. The imaging device 1 acquires an image of the rear of the vehicle body. The electronic mirror 2 can display the image of the rear of the vehicle body captured by the imaging device 1.

[0014] Fig. 2 is a side view showing an example of the mounting configuration of the electronic mirror 2 according to the embodiment. Fig. 2 is a side view of the vehicle compartment 7 viewed from the negative direction of the Y-axis. A pedestal 71 for mounting the electronic mirror 2 is provided in the vehicle compartment 7. The pedestal 71 is mounted on the inner side of the roof portion 62 (see Fig. 1) of the vehicle 5. The pedestal 71 may be mounted on the inner side of the windshield of the vehicle 5. The electronic mirror 2 includes a display panel 21, an operation switch 22, a housing 23, a support member 24, and a mounting member 25.

[0015] The display panel 21 is, for example, a liquid crystal panel, an organic EL panel, or the like. The operation switch 22 is provided at a lower portion of the housing 23. The display panel 21 is an example of a display panel. A user switches between the display mode and the mirror mode of the electronic mirror 2 by operating the operation switch 22. The housing 23 is a member that contains the display panel 21. Further, the housing 23 is supported by the pedestal 71 via the support member 24.

[0016] The support member 24 is a member having one end connected to the housing 23 and the other end connected to the pedestal 71 to support the housing 23. The support member 24 is made of, for example, aluminum alloy die-cast steel. The mounting member 25 is a member fixed to the support member 24 and mounted to the pedestal 71. The mounting member 25 is made of, for example, stainless steel. Note that the materials of the support member 24 and the mounting member 25 are not limited thereto.

[0017] Note that in Fig. 2 and the drawings relating to the electronic mirror 2 described below, the mutually orthogonal X-axis, Y-axis, and Z-axis respectively mean the front-rear direction, the left-right direction, and the up-down direction of the electronic mirror 2. Further, in the following description, when simply described as the X direction, the Y direction, or the Z direction, it means the respective axial direction, and includes both the positive direction and the negative direction.

[0018] Furthermore, when the direction is identified as the positive direction of the X-axis, it is one direction from the rear side to the front side; when identified as the positive direction of the Y-axis, it is one direction from the left side to the right side; and when identified as the positive direction of the Z-axis, it is one direction from the upper side to the lower side. When the direction is identified as the negative direction of the X-axis, it is one direction from the front side to the rear side; when identified as the negative direction of the Y-axis, it is one direction from the right side to the left side; and when identified as the negative direction of the Z-axis, it is one direction from the lower side to the upper side.

[0019] Figure 3 is a schematic diagram showing an example of the mounting configuration of the electronic mirror 2 according to the embodiment. Figure 3 shows a support member 24, a mounting member 25, a fixing member 26, and a pedestal 71. The fixing member 26 is inserted into an opening 251 of the mounting member 25 to fix the support member 24 and the mounting member 25. The fixing member 26 is, for example, a screw. Note that the fixing member 26 is not limited to a screw.

[0020] The mounting member 25 is located between the support member 24 and the pedestal 71. A protrusion 241 of the support member 24 is inserted into an opening 252 of the mounting member 25. The support member 24 to which the mounting member 25 is fixed is attached to the pedestal 71 by inserting the mounting member 25 into the pedestal 71 and rotating the mounting member 25 about an axis in the positive direction of the Z-axis, for example.

[0021] Figure 4 is a schematic diagram showing an example of the mounting member 25 according to the embodiment. The mounting member 25 shown in Figure 4 is a schematic diagram viewed from a surface facing the pedestal 71. The mounting member 25 has an opening 251 and an opening 252, and includes a plurality of first arms 253, a plurality of second arms 254, a plurality of reinforcing portions 255, and a plurality of reinforcing portions 256.

[0022] The opening 251 is an opening for inserting the fixing member 26 from the surface facing the pedestal 71. The opening 251 is an example of a second opening. The opening 251 is located approximately at the center of the mounting member 25. The opening 252 is an opening for inserting the protrusion 241 of the support member 24 from the surface facing the support member 24. The opening 252 is an example of a first opening.

[0023] The first arm 253 and the second arm 254 are members that extend radially along the opening 251, and each arm has the aforementioned opening 252. The first arm 253 and the second arm 254 are collectively referred to simply as arms.

[0024] The horizontal length from one end of the first arm 253 to one end of the opening 252 is defined as width L1, and the horizontal length from the other end of the first arm 253 (different from the one end) to the other end of the opening 252 (different from the one end) is defined as width L2. Width L1 is different from width L2. For example, as shown in Figure 4, width L1 is smaller than width L2.

[0025] The horizontal length from one end of the second arm 254 to one end of the opening 252 is defined as width L11, and the horizontal length from the other end of the second arm 254 (different from one end) to the other end of the opening 252 (different from one end) is defined as width L21. Width L11 is different from width L21. For example, as shown in Figure 4, width L11 is smaller than width L21. Widths L1 and L11 are examples of the first width. Widths L2 and L21 are examples of the second width.

[0026] The reinforcing portion 255 is a reinforcing member that extends horizontally along the radial direction centered on the opening 251, from approximately the center of the opening 251 toward the width L2 of the first arm 253. The reinforcing portion 256 is a reinforcing member that extends radially along the radial direction centered on the opening 251, from approximately the center of the opening 251 toward the opening 252 of the second arm 254. The horizontal length of the reinforcing portion 255 may be longer than the radial length of the reinforcing portion 256. The mounting member 25 does not necessarily have to include the reinforcing portion 256.

[0027] The worker attaches the mounting member 25 to the base 71 by rotating it around the positive Z-axis (arrow R1 shown in Figure 4). Next, the state in which the mounting member 25 is attached to the base 71 will be explained using Figure 5.

[0028] Figure 5 is a cross-sectional view showing an example of the mounting configuration of the mounting member 25 according to the embodiment. Figure 5 shows the protruding portion 241 of the support member 24, the mounting member 25, and the base 71. The mounting member 25 is provided with an insertion portion 258 for inserting into the base 71.

[0029] The insertion portion 258 is a member that extends from one end of the first arm 253 and the second arm 254, facing the opening 252 from the positive direction of the Z axis. The insertion portion 258 also has a tip portion 257 that is inserted into the base 71. The mounting member 25 has a rib 259 provided between one end of the first arm 253 and the second arm 254 and the insertion portion 258. In the case of the first arm 253, the rib 259 extends in the height direction at a position with a width L2 of the first arm 253. In the case of the second arm 254, the rib 259 extends in the height direction at a position with a width L21 of the second arm 254.

[0030] The protruding portion 241 of the support member 24 is inserted into the opening 252 of the mounting member 25 and is engaged with the recess 711 of the base 71. The worker inserts the insertion portion 258 of the mounting member 25 into the base 71, presses the protruding portion 241 of the support member 24 against the recess 711 of the base 71, and rotates the mounting member 25 around the axis in the positive direction of the Z axis. As a result, the tip of the insertion portion 258 rides up onto the base 71, and the mounting can be achieved by the engagement of the protruding portion 241 of the support member 24 and the recess 711 of the base 71.

[0031] Next, the state of the insertion portion 258 of the mounting member 25 when the mounting member 25 is rotated in the positive Z-axis direction will be explained using Figures 6 and 7. Figures 6 and 7 are schematic diagrams showing an example of the mounting configuration of the mounting member 25 according to the embodiment. Figures 6 and 7 show the mounting member 25 and the base 71. In Figures 6 and 7, the insertion portion 258 of the mounting member 25 is in a state where it has been rotated by an operator around the axis in the positive Z-axis direction (arrow R1) relative to the base 71. Also, the width L1 (width L11) is located on the side into which the base 71 to which the mounting member 25 is attached is inserted.

[0032] In Figure 6, when the insertion portion 258 of the mounting member 25 is inserted into the base 71, the tip portion 257 of the insertion portion 258 comes into contact with the base 71. Also, the surface C1 of the tip portion 257 that is in contact with the base 71 twists in the direction of arrow T1, causing a large displacement of the width L1 of the mounting member 25. At that time, the rib 259 reduces the displacement of the insertion portion 258 of the mounting member 25 in the X-axis direction. Furthermore, in Figure 7, once the insertion portion 258 of the mounting member 25 is fully inserted into the base 71, the twist of the tip portion 257 of the insertion portion 258 is released in the direction of arrow T2, generating a pressing force against the base 71.

[0033] When an operator attaches the electronic mirror 2 to the vehicle-side base 71, the surface C1 of the tip 257 of the insertion portion 258 that contacts the base 71 twists in the direction of arrow T1, causing a large displacement of the width L1 of the mounting member 25, thus eliminating the need for significant force. Furthermore, since the operator does not need to exert much force, the use of jigs for installation becomes unnecessary, improving work efficiency and reducing the process load, thus reducing the number of work hours.

[0034] Furthermore, when the electronic mirror 2 is attached to the base 71 on the vehicle side, the tip 257 of the insertion part 258 generates a pressing force against the base 71. Therefore, even if the vehicle 5 vibrates while driving, the electronic mirror 2 will not detach from the base 71.

[0035] As described above, the electronic mirror 2 according to this embodiment includes a support member 24 that supports a housing 23 containing a display panel, a mounting member 25 having a plurality of arms, and a fixing member 26 that fixes the support member 24 and the mounting member 25. The arms have a first opening into which a protruding portion 241 of the support member 24 is inserted, and the first width, which is the horizontal dimension from one end of the arm to one end of the first opening, is different from the second width, which is the horizontal dimension from a different end of the arm to a different end of the first opening. The first width is located on the side into which the base 71 for attaching the mounting member 25 is inserted, and the first width is smaller than the second width.

[0036] For example, when an operator attaches the electronic mirror 2 to the vehicle-side base 71, the surface C1 of the tip 257 of the insertion portion 258 that contacts the base 71 twists in the direction of arrow T1, causing a large displacement of the width L1 of the mounting member 25, thus eliminating the need for significant force. As a result, the operator does not need to exert much force, eliminating the need for installation work using jigs, improving work efficiency and reducing the process load, thus reducing the number of work hours. Therefore, the electronic mirror 2 according to this embodiment can reduce the number of work hours.

[0037] Furthermore, the mounting member 25 has a second opening into which the fixing member 26 is inserted, and the second opening is located approximately at the center of the mounting member 25. In addition, the mounting member 25 is provided with a reinforcing portion 255 that extends horizontally along the radial direction centered on the second opening, from approximately the center toward the second width. The mounting member 25 also has a rib 259 that extends in the height direction at the position of the second width of the arm.

[0038] For example, the mounting member 25 has a second opening positioned approximately at the center of the mounting member 25, and is equipped with a reinforcing portion 255. This makes it easier for the surface C1 of the tip portion 257 of the insertion portion 258 that contacts the base 71 to twist when an operator attaches the electronic mirror 2 to the base 71 on the vehicle side, contributing to a larger displacement of the width L1 of the mounting member 25. In addition, the mounting member 25 has a rib 259, which reduces the displacement of the insertion portion 258 of the mounting member 25 in the X-axis direction.

[0039] The embodiments described above can also be modified and implemented as appropriate by changing some of the configurations or functions of each of the devices described above. Therefore, the following describes modifications of the embodiments described above as other embodiments. In the following, we will mainly describe the differences from the embodiments described above, and will omit detailed explanations of points that are common with what has already been described.

[0040] (First variation) For example, when the electronic mirror 2 is mounted on the base 71, if a user or worker adjusts the angle of the electronic mirror 2, slight sliding may occur on the surface C1 that contacts the base 71 and the tip 257 of the mounting member 25, or noise may be generated due to vibration of the mounting member 25. Therefore, in the first modified example, a structure for reducing vibration of the mounting member 25 will be explained using Figure 8.

[0041] Figure 8 is a schematic diagram showing an example of the mounting configuration of the electronic mirror 2 according to the first modified example. Figure 8 shows a support member 24, a mounting member 25, a fixing member 26, a first vibration damping member 27, and a second vibration damping member 28. The first vibration damping member 27 and the second vibration damping member 28 are members that dampen the vibration of the mounting member 25. The first vibration damping member 27 and the second vibration damping member 28 are made of, for example, rubber material or resin material.

[0042] The rubber material is, for example, butyl rubber, silicone rubber, or ethylene propylene rubber. The resin material is, for example, a urethane-based material. The first vibration damping member 27 is located between the mounting member 25 and the fixing member 26. The second vibration damping member 28 is located between the support member 24 and the mounting member 25.

[0043] The fixing member 26 is inserted in the negative direction of the Z-axis into the opening of the first vibration damping member 27, the opening 251 of the mounting member 25, and the opening of the second vibration damping member 28, thereby fixing the support member 24, the first vibration damping member 27, the second vibration damping member 28, and the mounting member 25.

[0044] As described above, the electronic mirror 2 according to the first modified example comprises a support member 24 that supports a housing 23 containing a display panel, a mounting member 25 having a plurality of arms, a fixing member 26 that fixes the support member 24 and the mounting member 25, a first vibration damping member 27 that dampens vibrations of the mounting member 25, and a second vibration damping member 28 that dampens vibrations of the mounting member 25. The first vibration damping member 27 is located between the mounting member 25 and the fixing member 26, and the second vibration damping member 28 is located between the support member 24 and the mounting member 25.

[0045] This makes it possible to reduce, for example, the slight sliding motion that occurs on the surface C1 that contacts the base 71 and the tip 257 of the mounting member 25 when the user or worker adjusts the angle of the electronic mirror 2 while it is mounted on the base 71, as well as the generation of noise due to vibrations of the mounting member 25.

[0046] (Second variation) In the first modified example described above, the electronic mirror 2 was described as comprising a first vibration damping member 27 and a second vibration damping member 28, but it is not limited to this. For example, the electronic mirror 2 may comprise at least one of the first vibration damping member 27 and the second vibration damping member 28.

[0047] The electronic mirror 2 according to the second modified example comprises a support member 24 that supports a housing 23 containing a display panel, a mounting member 25 having a plurality of arms, and a fixing member 26 that fixes the support member 24 and the mounting member 25. The electronic mirror 2 also comprises at least one of a first vibration damping member 27 that dampens vibrations of the mounting member 25 and a second vibration damping member 28 that dampens vibrations of the mounting member 25, the first vibration damping member 27 being located between the mounting member 25 and the fixing member 26, and the second vibration damping member 28 being located between the support member 24 and the mounting member 25.

[0048] According to at least one embodiment described above, it is possible to reduce the amount of work required.

[0049] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of Symbols]
