Transport equipment

The present disclosure relates to a display device, and more particularly to a display device of a transportation device having a first seating area.

Due to the limited space for accommodating the screen, the rear seat screens of existing transportation devices are usually of relatively small size, and the rear seat passengers have a low level of comfort in viewing the screen images.

Therefore, a display device design is needed that can improve the comfort of passengers viewing screen images.

To solve the above problems, the disclosed embodiment provides a display device located in a transportation device having a first seating area, including a display unit, a mechanical platform, and a mechanical axis group. The mechanical platform is arranged corresponding to the first seating area. The mechanical axis group is arranged on the mechanical platform, including a first axis, a second axis, a third axis, and a fourth axis. The first axis is connected to the display unit and drives the display unit to move along a horizontal direction. The second axis is connected to an upper end of the display unit and drives the display unit to rotate around a second axis. The third axis is connected to the second axis. The fourth axis is connected to the third axis and drives the display unit to rotate around a third axis.

To solve the above problems, the disclosed embodiment further provides a transport device, including a first seating area, a display device, a top, a storage space, and a control interface. The top corresponds to the first seating area. The storage space is configured to store the display device and is disposed adjacent to the top. The control interface is electrically connected to the display device. When the control interface provides an unfolding signal to the display device, the display device moves away from a storage position. When the control interface provides a storage signal to the display device, the display device moves toward the storage position.

That is, the display unit 140 is also accommodated on the top 110, and the display unit 140 is accommodated above the first seat area 120. In some embodiments, the display unit 140 is located in the accommodation position 253, and the accommodation position 253 is between the mechanical platform 150 and the first top 110, but the present disclosure is not limited thereto.

Please refer to Figure 2, Figure 3A, Figure 3B and Figure 3C. Figure 2 is a schematic diagram of the display unit 140, the mechanical platform 150, and the mechanical axis group 160 according to some embodiments of the present disclosure. Figure 3A is a schematic diagram of the mechanical axis group 160 driving the display unit 140 to move relative to the mechanical platform 150 according to some embodiments of the present disclosure. Figure 3B is a schematic diagram of the mechanical axis group 160 driving the display unit 140 to move relative to the mechanical platform 150 according to some embodiments of the present disclosure. Figure 3C is a schematic diagram of the mechanical axis group 160 driving the display unit 140 to move relative to the mechanical platform 150 according to some embodiments of the present disclosure.

As shown in FIG. 2 , FIG. 3A , FIG. 3B , and FIG. 3C , the mechanical shaft assembly 160 may be disposed on the mechanical platform 150 , and the mechanical shaft assembly 160 may connect the display unit 140 to the mechanical platform 150 .

The mechanical platform 150 may include a body 151 , guide rails 152 , slide rails 153 , and a motor 154 . The mechanical axis assembly 160 may include a first axis 161 , a second axis 162 , a third axis 163 , a transverse axis 164 , and a fourth axis 165 .

One end of the first shaft portion 161 may be connected to the upper end of the display unit 140 , and the other end of the first shaft portion 161 may be connected to the horizontal shaft 164 .

The motor 154 of the mechanical platform 150 can drive the transverse axis 164 to move, so that the first axis 161 can move along the guide rail 152 set on the body 151 of the mechanical platform 150.

The guide rail 152 can extend along the horizontal direction HD, so that the first axis 161 can drive the display unit 140 to move along the horizontal direction HD. According to some embodiments of the present disclosure, the mechanical axis assembly 160 can have two first axis portions 161 to be more stably connected to the display unit 140. In some embodiments, the display unit 140 moves a distance from the accommodation space 211 (or the accommodation position 253) along the guide rail 152 to the folded position (not shown) via the first axis portion 161, but the present disclosure is not limited thereto.

The second shaft 162 may be disposed between the two first shafts 161. One end of the second shaft 162 may be connected to the upper end of the display unit 140, and the other end of the second shaft 162 may be connected to the third shaft 163. Also, the second shaft 162 may drive the display unit 140 to rotate around a second axis AX2.

The third shaft portion 163 may be disposed between the two first shaft portions 161. One end of the third shaft portion 163 may be connected to the second shaft portion 162, and the other end of the third shaft portion 163 may be connected to the fourth shaft portion 165.

The fourth axis 165 may be disposed between the third axis 163 and the body 151 of the mechanical platform 150. One end of the fourth axis 165 may be connected to the third axis 163, and the other end of the fourth axis 165 may be connected to the transverse axis 164. Therefore, the fourth axis 165 may be indirectly connected to the first axis 161.

When the motor 154 of the mechanical platform 150 drives the transverse axis 164 to move, the fourth axis 165 can move along the slide rail 153 of the mechanical platform 150. The slide rail 153 is connected to the body 151 of the mechanical platform 150.

Moreover, the slide rail 153 extends along the horizontal direction HD below the main body 151 of the mechanical platform 150, and in a cross-sectional direction, the sliding track of the slide rail 153 passes upward through the main body 151 of the mechanical platform 150 at the end 150' of the mechanical platform 150 (Figure 3A).

When the fourth axis 165 moves along the slide rail 153 of the mechanical platform 150, the third axis 163 will also move along with the fourth axis 165, thereby driving the display unit 140 to move.

According to some embodiments of the present disclosure, the third axis portion 163 can drive the display unit 140 to rotate around a third axis AX3.

A width 150W of the mechanical platform 150 may be smaller than a width 140W of the display unit 140, and the mechanical platform 150 may have a hole 150a. In this way, the size of the mechanical platform 150 can be reduced, and the weight of the mechanical platform 150 can be reduced, thereby reducing costs or reducing power consumption (fuel consumption) of the transport device during travel.

Please refer to FIG. 4, which is a schematic diagram of a transport device 200 according to some embodiments of the present disclosure. It should be noted that although FIG. 4 shows the transport device 200 as a car, the present disclosure is not limited thereto. The transport device 200 may be similar to the transport device 100, and will not be described in detail here.

The transportation device 200 may include a first top portion 210 , a first seating area 220 , a second seating area 230 , a display unit 240 , a driving source 270 , and a second top portion 290 .

The first top 210, the first seating area 220 and the second seating area 230 may be similar to the top 110, the first seating area 120 and the second seating area 130, and will not be described in detail herein.

The transport device may further include a housing space 211 corresponding to the first top portion 210, and the housing space 211 may accommodate the display unit 240. In this embodiment, the housing space 211 may be located above the first seating area 220, and in the normal direction of the transport device 200, the projection of the housing space 211 overlaps the first top portion 210, in other words, the display unit 240 may be accommodated above the first seating area 220. Similarly, the second top portion 290 may correspond to the second seating area 230; in other words, the second top portion 290 may be located above the second seating area 230, and the second top portion 290 may be the ceiling inside the transport device 200. In some embodiments, the accommodation space may be a space between seats (eg, a driver's seat and a passenger seat) and the top of the transport device, or may be a closed space or a semi-open space enclosed by a housing (not shown) for accommodating the display unit 240, but is not limited thereto.

According to some embodiments of the present disclosure, the transportation device 200 is typically designed such that a distance S1 between the first seating area 220 and a first top 210 above the first seating area 220 may be greater than a distance S2 between the second seating area 230 and a second top 290 above the second seating area 230 .

Therefore, accommodating the display unit 240 in the first top portion 210 above the first seating area 220 can effectively utilize the space between the user and the first top portion 210 above the first seating area 220, and can reduce the possibility of users sitting in the second seating area 230 feeling oppressed.

Furthermore, since the first top portion 210 above the first seating area 220 can accommodate a display unit 240 of a larger size, the user can have a better viewing experience.

The driving source 270 can drive the display unit 240. According to some embodiments of the present disclosure, the driving source 270 can drive the display unit 240 to move from the accommodation position 253 (which can be located in the accommodation space 211) to an extended position 251, or the driving source 270 can drive the display unit 240 to move from the extended position 251 to the accommodation position 253.

When the display unit 240 is not in use, the display unit 240 can be placed in the accommodation position 253 to reduce damage to the display unit 240 and to reduce injuries to the user caused by hitting the display unit 240. For example, after the transport device 200 is parked, when the display unit 240 is not in use, or when no one is sitting in the second seat area 230, the display unit 240 can be placed in the accommodation position 253.

According to some embodiments of the present disclosure, when the display unit 240 is located in the accommodation position 253, a display panel 241 of the display unit 240 may face the first top portion 210 of the transport device 200. However, according to some other embodiments of the present disclosure, when the display unit 240 is located in the accommodation position 253, a display surface 241 of the display unit 240 may face away from the first top portion 210 of the transport device 200.

When the display unit 240 is to be used, the display unit 240 may be located at the unfolded position 251 so that the user can view the content displayed by the display unit 240 .

According to some embodiments of the present disclosure, the unfolded position 251 may be between the first seating area 220 and the second seating area 230. According to some embodiments of the present disclosure, when the display unit 240 is at the unfolded position 251, the display surface 241 of the display unit 240 may face the second seating area 230, so that the user sitting in the second seating area 230 can view the content displayed by the display unit 240.

The transport device 200 may further include a control interface (see FIG. 8 ). The control interface includes, but is not limited to, a circuit board, a controller, a transceiver, or other suitable control elements. The control interface may be electrically connected to the display unit 240 to provide different signals to the display unit 240. When the control interface provides an unfolding signal to the display unit 240, the display unit 240 may move away from the accommodation position 253, and the display unit 240 may move toward the unfolded position 251.

When the control interface provides an accommodation signal to the display unit 240 , the display unit 240 can move toward the accommodation position 253 , and the display unit 240 can move away from the unfolded position 251 .

The transport device 200 may include a sensor (not shown). According to some embodiments of the present disclosure, the sensor may be a positioning sensor or a force sensor, but the present disclosure is not limited thereto.

According to some embodiments of the present disclosure, a positioning sensor or a force sensor may be disposed on the display unit 240, or on a mechanical platform (similar to the mechanical platform 150) that supports the display unit 240.

According to some embodiments of the present disclosure, the positioning sensor can sense the position of the display unit 240. For example, the positioning sensor can sense whether the display unit 240 is located at the accommodation position 253 or the unfolded position 251.

According to some embodiments of the present disclosure, when the control interface provides an expansion signal to the display unit 240, and when the positioning sensor senses that the display unit 240 is not in the expanded position 251, the driving source 270 drives the display unit 240 to move toward the expanded position 251 until the positioning sensor senses that the display unit 240 is in the expanded position 251.

According to some embodiments of the present disclosure, when the control interface provides an accommodation signal to the display unit 240, and when the positioning sensor senses that the display unit 240 is not in the accommodation position 253, the driving source 270 drives the display unit 240 to move toward the accommodation position 253 until the positioning sensor senses that the display unit 240 is in the accommodation position 253.

According to some embodiments of the present disclosure, the force sensor can sense whether the display unit 240 is subjected to external force. For example, the force sensor can sense whether the display unit 240 contacts or hits other objects, such as a user or other components of the transport device 200, during movement.

According to some embodiments of the present disclosure, when the driving source 270 drives the display unit 240 to move toward the expanded position 251, and when the display unit 240 touches or collides with the user or other components of the transportation device 200, the force sensor can provide a signal to the driving source 270 to cause the driving source 270 to drive the display unit 240 to stop moving or move toward the accommodating position 253.

According to some embodiments of the present disclosure, when the driving source 270 drives the display unit 240 to move toward the accommodation position 253, and when the display unit 240 touches or collides with the user or other components of the transportation device 200, the force sensor can provide a signal to the driving source 270 to cause the driving source 270 to drive the display unit 240 to stop moving or move toward the unfolded position 251.

According to some other embodiments of the present disclosure, when the control interface provides an expansion signal to the display unit 240, the driving source 270 drives the display unit 240 to move toward the expansion position 251 for an expansion time, so that the display unit 240 is located at the expansion position 251.

According to some other embodiments of the present disclosure, when the control interface provides an accommodation signal to the display unit 240, the driving source 270 drives the display unit 240 to move toward the accommodation position 253 for an accommodation time, so that the display unit 240 is located at the accommodation position 253.

Please refer to FIG. 5 , which is a schematic diagram showing the unit 240 at different positions.

In the embodiment of FIG. 5 , the folded position 252 may be between the accommodation position 253 and the unfolded position. The folded position 252 and the accommodation position 253 may be separated by a distance S3. According to some embodiments of the present disclosure, the distance S3 may be parallel to the horizontal direction HD.

When the display unit 240 is at the folded position 252 , the display unit 240 can be quickly moved to the accommodating position 253 or the unfolded position 251 .

For example, when the user does not use the display unit 240 temporarily, the display unit 240 can be folded in the folded position 252, so that when the user wants to use the display unit 240, the display unit 240 can be quickly moved to the unfolded position 251.

For example, when encountering an emergency situation (eg, emergency braking, collision, etc.), the display unit 240 can be quickly moved from the extended position 251 to the retracted position 252 to reduce the possibility of the user colliding with the display unit 240.

According to some embodiments of the present disclosure, the display unit 240 may move along the horizontal direction HD between the accommodation position 253 and the folded position 252. According to some embodiments of the present disclosure, when the display unit 240 moves along the horizontal direction HD between the accommodation position 253 and the folded position 252, the display unit 240 may not rotate.

For example, if the display unit 240 is located in the accommodation position 253, the display surface 241 of the display unit 240 faces the first top portion 210 of the transport device 200, then when the display unit 240 is located in the folded position 252, the display panel 241 of the display unit 240 faces the first top portion 210 of the transport device 200.

In the embodiment of FIG. 5 , the control interface (see FIG. 8 ) may provide a folding signal to the display unit 240 . Furthermore, when the control interface provides the folding signal to the display unit 240 , the display unit 240 may move toward the folded position 252 .

According to some embodiments of the present disclosure, the display unit 240 can move from the accommodation position 253 to the folded position 252. According to some embodiments of the present disclosure, the display unit 240 can move from the extended position 251 to the folded position 252.

According to some embodiments of the present disclosure, the sensor of the transport device 200 may also be an optical sensor, an ultrasonic sensor, etc., but the present disclosure is not limited thereto.

The sensor can detect the position of the user, and then adjust the distance from the storage position 253 to the folded position 252. For example, the sensor can sense the position of the second seat area 230, the body shape of the user, whether there is a child seat, or whether there are other obstructions, etc., to determine the distance from the storage position 253 to the folded position 252.

In this way, the display unit 240 can be reduced from contacting or impacting the user or other components of the transportation device 200 when moving.

According to some embodiments of the present disclosure, the sensor may be disposed in the middle of the first seat area 220. For example, when the first seat area 220 is the area from the driver's seat to the passenger seat, the sensor may be disposed in the central control area (between the driver's seat and the passenger seat).

According to some embodiments of the present disclosure, the sensor may be disposed at a corner of the top of the transport device 200. For example, the sensor may be disposed at a corner of the second top portion 290 above the second seating area 230 to sense the position of the second seating area 230, the size of the user, whether there is a child seat, or whether there are other obstructions.
